Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of embodiment in many different forms than those described herein and those skilled in the art will be able to make similar modifications without departing from the spirit of the application and therefore the application is not limited to the specific embodiments disclosed below. Furthermore, well-known features may be omitted or simplified in order not to obscure the described embodiments.
Referring now to the drawings, wherein like reference numerals refer to like parts throughout the several views, FIGS. 1A, 1B, and 1C show assembled and exploded schematic views of a selection assembly 100 for an inflatable product 500 (FIG. 5), such as an inflatable mattress, an inflatable table and chair, an inflatable swimming pool, and other inflatable articles 500. Inflatable product 500 includes a plurality of air chambers, and selection assembly 100 includes a plurality of air outlets corresponding to the aforementioned air chambers, each air outlet configured to communicate at least one air chamber with the environment external to inflatable product 500 such that air from the external environment can enter the air chamber. As shown in FIG. 5, the inflatable product 500 includes an inflatable body, such as two air chambers, wherein the inflatable body includes a first air chamber 502 and a second air chamber 504, and correspondingly, as shown in FIG. 1C, the selection assembly 100 includes a first air outlet 112 and a second air outlet 114 corresponding to the first air chamber 502 and the second air chamber 504, respectively.
With continued reference to fig. 1A, 1B, and 1C, the selection assembly 100 includes a housing 102, the housing 102 defining a selection chamber 110 and an inflator attachment portion 104, hereinafter referred to as the attachment portion 104. As shown in fig. 1B, the selection assembly 100 further includes a cover 106, the cover 106 covering an opening 107 defined by the attachment portion 104. The cover plate 106 is provided with an air inlet 108, and the air inlet 108 is communicated with a first inner area 120 defined by the selection chamber 110, and allows external air to enter the first inner area 120. The air inlet 108 may be a three-in-one air nozzle or a through hole may be formed in the cover plate 106 according to different embodiments, which is exemplified by a three-in-one air nozzle in this embodiment. During inflation, the air outlet of the air pump is connected to the air inlet 108, and outside air is delivered into the first interior region 120 via the air inlet 108. Air within inflatable product 500 exits first interior region 120 during deflation and is then discharged into the external environment through air inlet 108.
The attachment portion 104 is configured to form a substantially airtight seal with a surface of the inflatable product 500. The attachment portion 104 is typically welded into a surface opening of the inflatable product 500 or may be secured to the inflatable product 500 in a different manner, thereby forming a substantially airtight seal between the selection module 100 and the inflatable product 500.
The selection chamber 110 is configured to be inserted into the inflatable product 500 such that the selection chamber 110 is disposed substantially inside the inflatable product 500, as shown in fig. 5. As shown in fig. 1B and 1C, the first air outlet 112 and the second air outlet 114 are respectively provided on the chamber walls 116, 117 of the selection chamber 110, both communicating with the first interior region 120, and air enters the first interior region 120 through the air inlet 108 and then optionally enters the first air chamber 502 through the first air outlet 112, or enters the second air chamber 504 through the second air outlet 114, or enters both the first air chamber 502 and the second air chamber 504 through the first air outlet 112 and the second air outlet 114.
As shown in fig. 1C, the first air outlet 112 is provided with a first air valve 122 for closing or opening the same, and the second air outlet 114 is provided with a second air valve 124 for closing or opening the same. In the absence of external forces, the first air valve 122 closes the first air outlet 112 and the second air valve 124 closes the second air outlet 114; the first air outlet 112 may be opened when an external force is applied to the first air valve 122 to open it, and the second air outlet 114 may be opened when an external force is applied to the second air valve 124 to open it. An alternative configuration of the first gas valve 122 or the second gas valve 124 is described below using the first gas valve 122 as an example. The first air valve 122 may include an air permeable mesh enclosure 131 disposed over the first air outlet 112, a pressure plate 133 disposed within the mesh enclosure 131, a sealing ring 135 disposed on the pressure plate 133, and a spring 137 disposed between the pressure plate 133 and the mesh enclosure 131. Without the action of external force, the spring 137 presses the pressing plate 133 and the sealing ring 135 toward the first air outlet 112, so that the sealing ring 135 is pressed against the first air outlet 112 to close the first air outlet 112; the external force can overcome the elastic force of the spring 137 to push the pressing plate 133 to move toward the mesh cover 131, so that the sealing ring 135 is separated from the first air outlet 112, and the first air outlet can be opened.
As shown in fig. 1B, a valve switch 140 is disposed in the first inner area 120 for opening the first air outlet 112 or the second air outlet 114, and the valve switch 140 can selectively open the first air valve 122 or the second air valve 124 to selectively open the first air outlet 112 or the second air outlet 114. When the first air outlet 112 is open and the second air outlet 114 is closed, air entering the first interior region 120 from the air inlet 108 enters the first plenum 502 via the first air outlet 112; when the first air outlet 112 is closed and the second air outlet 114 is open, air entering the first interior region 120 from the air inlet 108 enters the second plenum 504 via the second air outlet 114; when both the first air outlet 112 and the second air outlet 114 are open, air entering the first interior region 120 from the air inlet 108 enters the first plenum 502 and the second plenum 504 via the first air outlet 112 and the second air outlet 114, respectively; when both the first air outlet 112 and the second air outlet 114 are closed, air within the first interior region 120 cannot enter the first plenum 502 and the second plenum 504. Conversely, if no air enters the air inlet 108 and the air pressure of the first air chamber 502 or the second air chamber 504 is greater than the external ambient air pressure, the air in the first air chamber 502 or the second air chamber 504 can enter the first inner region 120 through the opened first air outlet 112 or the opened second air outlet 114, and then can be exhausted from the external environment through the air inlet 108.
Referring to fig. 1D, the valve switch 140 may include a shaft rotating body 142, the shaft rotating body 142 having a rotation axis 400, the shaft rotating body 142 may rotate about the rotation axis 400, and the shaft rotating body 142 rotates to selectively open the first air valve 122 or the second air valve 124. Specifically, the outer surface of the pivoting body 142 is provided with a protrusion protruding outwards, the protrusion abuts against and acts on the first air valve 122 or the second air valve 124 to open the first air valve 122 or the second air valve 124, the number of the protrusions is set according to actual requirements, and when one protrusion is provided, the first air valve 122 and the second air valve 124 cannot be opened at the same time. The protrusion cannot be disposed in the direction in which the rotation axis 400 extends, which ensures that the protrusion can change positions along with the rotation of the shaft rotating body 142, thereby achieving the effect of selectively operating the first air valve 122 or the second air valve 124.
In one embodiment, as shown in fig. 1D, the pivoting body 142 is substantially in the shape of a ratchet wheel, and has a first protrusion 146 and a second protrusion 147 on the outer edge thereof, and the first protrusion 146 or the second protrusion 147 may be offset from the first air valve 122 or the second air valve 124 or abut against the first air valve 122 or the second air valve 124 to act on the first air valve 122 or the second air valve 124 as the pivoting body 142 rotates. The shape of the shaft main body 142 can be selected according to specific requirements, and for example, the shaft main body can be wheel-shaped, disc-shaped, spherical, etc., and the position of the protrusion on the shaft main body 142 can be adaptively set according to the positions of the first air valve 122 and the second air valve 124, for example, the protrusion can be on the periphery or the disc surface of the disc-shaped, etc.
When the pivoting body 142 is pivoted to this position, as shown in fig. 2A, the first protrusion 146 acts on the first air valve 122, the second protrusion 147 acts on the second air valve 124, and both the first air outlet 112 and the second air outlet 114 are open, air can be discharged (or introduced) from the first air outlet 112 and the second air outlet 114. As shown in fig. 2B, when the pivoting body 142 is rotated to this point, the second protrusion 147 is misaligned with both the first air valve 122 and the second air valve 124, the first protrusion 146 acts on the second air valve 124, the second air outlet 114 is opened, the first air outlet 112 is closed, and air can be discharged only from the second air outlet 114. As shown in fig. 2C, when the pivoting body 142 is pivoted to this position, the first projection 146 and the second projection 147 are offset from the first air valve 122 and the second air valve 124, and the first air outlet 112 and the second air outlet 114 are closed, so that air cannot be discharged. As shown in fig. 2D, when the pivoting body 142 is pivoted to the position, the first protrusion 146 is offset from both the first air valve 122 and the second air valve 124, and the second protrusion 147 acts on the first air valve 122, so that the first air outlet 112 is opened, the second air outlet 114 is closed, and air can be discharged from the first air outlet 112.
It should be understood that the number of the protrusions is not limited to the above-given examples, and those skilled in the art can arrange an appropriate number of the protrusions according to the selection mode, the number of the air outlets, the single rotation angle of the shaft rotating body, and the like. Other embodiments regarding the number of protrusions provided will be apparent from the examples below. As regards the other number of embodiments of air outlets or air chambers, the implementation of the solution is possible without any inventive effort for the skilled person, since it is only a simple increase or decrease in the number, and the present application is not illustrated in detail.
The selection assembly 100 may also include a drive mechanism for driving rotation of the shaft rotating body 142. In one embodiment, the driving mechanism may be a manual rotation mechanism (not shown) disposed on the cover 106, a rotation shaft of the manual rotation mechanism is disposed in the shaft main body 142 along a rotation axis 400 and is fixedly connected to the shaft main body 142, and the shaft main body 142 can be rotated around the rotation axis by rotating the manual rotation mechanism. The manual turning mechanism may be, for example, a knob, a rocker, or the like. The state of the selection component 100 corresponding to the position where the manual rotation mechanism rotates may be marked on the manual rotation mechanism or the cover plate 106, for example, the state is marked by "off" corresponding to both the first air valve 122 and the second air valve 124 being closed, the state is marked by "on" corresponding to both the first air valve 122 and the second air valve 124 being open, the state is marked by "first" corresponding to both the first air valve 122 and the second air valve 124 being closed, and the state is marked by "second" corresponding to both the first air valve 122 and the second air valve 124 being open, so that the selection component is conveniently rotated to a desired state when in use.
