Description

Technical Field

[0001] The utility model relates to the technical field of air pump application, in particular to a charging and discharging air interface structure. Background Art

[0002] Inflatable products are becoming more and more popular among consumers due to their small size, convenience for carrying and collection. Inflatable products on the market, such as inflatable mattresses, inflatable beds, inflatable sofas, inflatable pillows, inflatable footrests and inflatable toys, are mostly inflated into the cavity through air valves, and inflatable products can be transformed into various specific shapes. In order to make the inflation and deflation operation more convenient, built-in air pumps fixedly installed on inflatable products have appeared on the market.

[0003] The built-in air pump is fixedly installed on the inflatable product. A built-in air pump can only be used one-to-one with the inflatable product, and it is not convenient to charge and repair the air pump. Once the air pump is damaged, it either takes a lot of time and energy to repair it, or it is connected to the inflatable product and discarded together.

[0004] In view of this, there are currently structures on the market that can separate the movement of the air pump from the inflatable product. For example, a utility model patent with a publication number of CN219691779U and a publication date of September 15, 2023 discloses a waterproof air pump with a detachable movement, which includes a waterproof housing and an air pump movement detachably connected to the waterproof housing. The air pump movement can be disassembled and separated as a whole relative to the housing, which is convenient for the maintenance or replacement of the air pump movement. One air pump movement can be used with multiple inflatable products, which is flexible and convenient to use. However, when the air pump is applied to inflatable products, the air pump can only inflate the inflatable product. If deflation is required or manual inflation is required when the air pump movement is damaged, an additional deflation valve can only be set on the inflatable product to achieve this, resulting in a complex structure of the inflatable product, and the user's inflation and deflation operations are troublesome, and the user's inflation and deflation operations are low in convenience and flexibility. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide an inflation and deflation interface structure, through which the inflatable product can be inflated and deflated without additionally providing an air valve on the inflatable product, thereby improving the convenience of the inflation and deflation operation.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] The accommodating chamber is connected to the valve body chamber through the first air hole; the push rod is connected to the inside of the shell, and its lower end movably abuts against the one-way valve; one end of the elastic fixing member is connected to the bottom cover, and the other end abuts against the lower end of the one-way valve; the one-way valve abuts against the lower end of the shell through the elastic fixing member, and seals the first air hole to cut off the communication between the accommodating chamber and the valve body chamber.

[0009] The interface shell also includes an upper cover which is sealed and connected to the upper end of the shell.

[0010] The upper cover is provided with a third air hole, and the third air hole is provided with a valve plug.

[0011] The upper cover is connected to the shell through threaded engagement; or, one end of the upper cover is hinged to the shell, and the other end is connected to the shell through an upper cover fastener.

[0012] The inner side wall of the shell is formed with a sliding groove, and the push rod is installed in the sliding groove.

[0013] A limit block is formed at the lower part of the push rod. When the push rod moves downward to a set stroke, the limit block presses against the bottom of the shell.

[0014] The outer side of the push rod is matched with a push rod matching piece, which is fixedly connected in the shell; the push rod matching piece is provided with a sliding limit groove, and the upper part of the push rod is provided with a clamping block, which is matched in the sliding limit groove, and the lower part of the sliding limit groove is formed with a clamping groove that matches the clamping block and limits the movement of the clamping block.

[0015] The one-way valve comprises a valve seat and a one-way valve plate arranged on the valve seat. The valve seat is provided with a valve hole. The one-way valve is located on the lower end surface of the valve seat and is sealed on the valve hole.

[0016] After adopting the above solution, the utility model sets a push rod that cooperates with the one-way valve on the interface shell, so that the interface shell can be inflated and deflated with the help of a built-in air pump, and can also be deflated independently, without the need to set an additional air valve on the inflatable product. At the same time, based on this structure, it also provides users with a variety of options for inflation and deflation, improving the convenience of users. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] like Figure 1-5 As shown, this embodiment discloses a gas charging and discharging interface structure, which includes an interface shell 100, and the interface shell 100 includes a shell 110 and a bottom cover 120 connected to the lower end of the shell 110. Among them, a first air hole 112 is provided at the bottom of the shell 110, and a receiving chamber 111 is formed inside the shell 110, and a push rod 140 that can move up and down is provided in the receiving chamber 111. A second air hole 122 is provided at the bottom of the bottom cover 120, and a valve body chamber 121 is formed inside the bottom cover 120, and a one-way valve 160 and an elastic fixing member 170 are provided in the valve body chamber 121.

[0045] The accommodating chamber 111 is connected to the valve body chamber 121 through the first air hole 112; the push rod 140 is connected to the inside of the housing 110, and its lower end movably abuts against the one-way valve 160. One end of the elastic fixing member 170 is connected to the bottom cover 120, and the other end abuts against the lower end of the one-way valve 160. The one-way valve 160 abuts against the lower end of the housing 110 through the elastic fixing member 170, and seals the first air hole 112, thereby blocking the communication between the accommodating chamber 111 and the valve body chamber 121.

[0046] The inflation and deflation interface structure of this embodiment is applied to inflatable products, and the shell can be welded to the inflatable product when in use.

[0047] like Figure 6As shown, when inflating an inflatable product, the air pump can be installed in the accommodating chamber 111 to inflate directly without holding the air pump. The air pump is installed in the accommodating chamber 111, and then the air pump is started. Under the action of the air pump, the one-way valve 160 opens, and the gas enters the inflatable product through the air pump, the first air hole 112, the valve body chamber 121 and the second air hole 122. The entire inflation process does not require the user to hold the air pump.

[0048] like Figure 7 As shown, when the inflatable product needs to be deflated, the air pump is taken out of the accommodating chamber 111, and then the push rod 140 is pushed downward, and the lower end of the push rod 140 pushes at least a portion of the one-way valve 160 away from the housing 110, and compresses the elastic fixing member 170, so that the accommodating chamber 111 and the valve body chamber 121 are connected. At this time, the gas inside the inflatable product will be discharged to the outside through the second air hole 122, the valve body chamber 121 and the accommodating chamber 111, thereby achieving the deflation of the inflatable product.

[0049] It can be seen that, through the inflation and deflation interface structure of this embodiment, inflation and deflation can be performed with the help of a built-in air pump, and deflation operations can also be performed independently, without the need to additionally provide an air valve on the inflatable product.

[0050] In this embodiment, a sliding groove 113 is formed on the inner wall of the housing 110 , and the push rod 140 is installed in the sliding groove 113 .

[0051] The outer side of the push rod 140 is matched with a push rod matching piece 150, and the push rod matching piece 150 is fixedly connected in the housing 110. A sliding limit groove 151 is provided on the push rod matching piece 150, and a clamping block 141 is provided on the upper part of the push rod 140, and the clamping block 141 is matched in the sliding limit groove 151. A clamping groove 152 is formed at the lower part of the sliding limit groove 151 to match the clamping block 141 and limit the movement of the clamping block 141. The outer side of the push rod 140 refers to the side of the push rod 140 away from the side wall of the housing 110. In this embodiment, the push rod matching piece 150 and the housing 110 are fixed in the following manner: a fixing groove is provided on the inner side wall of the housing 110, and the push rod matching piece 150 is installed in the fixing groove, and the lower end is clamped with the housing 110 through a buckle.

[0052] When the push rod 140 is pushed downward, the block 141 slides in the sliding limit groove 151. When the block 141 slides into the groove 152, the push rod 140 is released, and the push rod 140 can be kept in the groove 152. At this time, part of the one-way valve 160 is always away from the bottom of the housing 110, and the accommodating chamber 111 and the valve body chamber 121 are always connected. This makes it unnecessary for the user to always press down the push rod 140 when inflating and deflation.

[0053] In addition, a limit block 142 is formed at the lower part of the push rod 140. When the push rod 140 moves down to a set stroke, the limit block 142 presses against the bottom of the housing 110 to limit the push rod 140 from moving further downward. Of course, the control of the downward stroke of the push rod 140 can also be achieved by the sliding limit slot 151.

[0054] In this embodiment, the interface housing 100 further includes an upper cover 130, which is sealed to the upper end of the housing 110. Specifically, a sealing ring may be provided on the upper cover 130 to ensure the sealing between the housing 110 and the upper cover 130. The provision of the upper cover 130 may improve the sealing performance of the inflation and deflation interface and prevent the inflatable product from leaking.

[0055] The upper cover 130 is provided with a third air hole 131, and the third air hole 131 is provided with a valve plug 132. Figure 8 As shown, when the air pump adapted for the accommodating chamber 111 cannot be used normally, the upper cover 130 is covered on the shell 110, and then other electric air pumps or manual air pumps are used to inflate the inflatable product through the third air hole 131, thereby ensuring normal inflation of the inflatable product.

[0056] like Fig. 9 and Fig.10 As shown, the upper cover 130 is connected to the housing 110 by threaded engagement, wherein Fig. 9 The following is a normal thread connection. Fig.10 The 1 / 4 thread connection is shown. Alternatively, Figure 1 and Figure 4 As shown, one end of the upper cover 130 is hinged to the housing 110, and the other end is connected to the housing 110 through the upper cover fastener 133. The upper cover fastener 133 is movably mounted on the housing 110 through the fastener spring 134. When the upper cover 130 is closed downward on the housing 110, the upper cover 130 pushes the upper cover fastener 133 to move outward. When the upper cover 130 is closed in place, the fastener spring 134 pushes the upper cover fastener 133 to fasten in the upper cover 130. Alternatively, as Fig.11 and Fig.12 As shown, one end of the upper cover 130 is hinged to the housing 110, and the other end is connected to the housing 110 through an upper cover fastener 133. The upper cover fastener 133 is movably mounted on the upper cover 130 through a fastener spring 134. When the upper cover 130 is covered downward on the housing 110, the housing 110 pushes the upper cover fastener 133 to move inward. When the upper cover 130 is covered in place, the fastener spring 134 pushes the upper cover fastener 133 to be fastened in the housing 110.

[0057] In this embodiment, the one-way valve 160 includes a valve seat 161 and a one-way valve plate 163 disposed on the valve seat 161. The valve seat 161 is provided with a valve hole 162. The one-way valve 160 is located at the lower end surface of the valve seat 161 and is blocked on the valve hole 162. A sealing ring is provided on the valve seat 161 to ensure that the one-way valve 160 can be sealed and connected to the lower end of the housing 110.

[0058] In summary, the key point of the utility model is that the utility model provides a push rod 140 that cooperates with a one-way valve 160 on the interface housing 100, so that the interface housing 100 can be inflated and deflated with the help of a built-in air pump, and can also be deflated independently, without the need to provide an additional air valve on the inflatable product. At the same time, based on this structure, it also provides users with a variety of options for inflation and deflation, thereby improving the convenience of users.

[0059] The above description is only an embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
