Description

Technical Field

[0001] The present disclosure relates to the field of pump technology, and in particular to an air pump device and a receiving assembly. Background Art

[0002] Most of the current air pump devices use a single pump mode, for example, a single centrifugal pump is used, but the centrifugal pump cannot meet the high pressure requirements and is not suitable for some inflatable objects with pressure requirements; or a single plunger high-pressure pump is used, and although the plunger high-pressure pump can meet the high pressure requirements, the flow rate is low. For items such as inflatable boards and inflatable beds, the inflation time required is long and the inflation efficiency is too low.

[0003] In addition, in the current air pump device, the battery pack is pluggable and the battery compartment for accommodating the battery pack is arranged in the vertical direction and is arranged vertically parallel to the air pump. The battery pack in the battery compartment relies on its own gravity to achieve electrical connection with the electrical connector. However, this arrangement will increase the lateral width of the air pump device, inevitably making the output end face of the device wider, and for some scenes where the inflation interface of the inflatable object is constrained by other surrounding components, resulting in a small operable space left around the inflation interface, the wide output end face makes the air pump device unfavorable for carrying out inflation work. And the above-mentioned arrangement makes it difficult to arrange the wires inside the device, affecting the operation of the pump. In addition, because the battery pack relies on its own gravity to achieve electrical connection with the electrical connector, most battery packs are directly placed vertically in the battery compartment or simply fixed by tape. The air pump will vibrate during long-term operation, causing the battery pack to shake, affecting the reliability of the battery pack, and then affecting the normal operation of the air pump.

DETAILED DESCRIPTION

[0047] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0048] According to one embodiment of the present disclosure, the utility model provides an air pump device. Figure 1-15 As shown, an air pump device includes a housing 1, a battery compartment 3, a battery pack 2 pluggably connected to the battery compartment 3, and an elastic member 4; the housing 1 includes a housing body 11 and a battery compartment cover 12 that can be opened or covered on the housing body, and the battery compartment cover 12 can expose the battery pack 2 when opened; the battery compartment 3 is formed in the housing 1 along the horizontal direction so that the battery pack 2 can be pluggably connected to the battery compartment 3 along the horizontal direction;

[0049] The elastic member 4 is mounted on the battery compartment cover 12 , and is configured to form an elastic pressing force on the battery pack 2 to drive the battery pack 2 to be pressed against the electrical connector 31 when the battery compartment cover 12 and the shell body 11 are closed.

[0050] In this application, the horizontal direction is also the lateral direction. Figure 1 The direction shown in the X direction, the vertical direction is Figure 1 The direction shown in the Z direction.

[0051] In the air pump device of the present application, the battery compartment 3 is formed in the shell 1 along the horizontal direction, so that the battery pack 2 can also be plugged and connected to the battery compartment 3 in the horizontal direction. The advantage of such a setting is that it is convenient for arranging the cables of the air pump assembly and the battery pack in the shell, and it improves the space utilization rate in the shell, saves the width of the device in the lateral direction (horizontal direction), thereby reducing the lateral width of the output end of the device and improving the operation flexibility of the device. And because the battery compartment cover 12 can be opened or covered on the shell body 11, when the battery compartment cover 12 is opened, the battery pack 2 in the shell can be exposed, so that the battery pack 2 can be taken out / put in from the battery compartment more conveniently. And the present application arranges an elastic member 4 on the battery compartment cover. When the battery compartment cover 12 and the shell body 11 are covered, the elastic member 4 can press the battery pack 2 against the electrical connector 31, reducing the shaking of the battery pack 2 during the operation of the device, thereby ensuring the reliability of the battery pack.

[0052] For example, the elastic member 4 may be installed on the battery compartment 3, and the elastic member 4 is configured to form an elastic pressing force on the battery pack 2 to drive the battery pack 2 to be pressed against the electrical connector 31 when the battery compartment cover 12 and the housing body 11 are closed. When the battery compartment cover 12 is closed on the battery compartment, the elastic member 4 on the battery compartment protrudes to press the battery pack, thereby pressing the battery pack 2 against the electrical connector 31.

[0053] In this embodiment, the elastic member 4 is configured to form an elastic pressing force on the battery pack 2, so the elastic member 4 is preferably made of metal material. The elastic member 4 made of metal material has high strength and can maintain elastic force for a long time, thereby improving the service life of the device. In addition, the elastic member 4 can also be a flexible material, such as a silicone material, which can prevent water from entering the battery compartment and can also press the battery pack 2.

[0054] For example, the elastic member 4 is a spring sheet, the first end of which is mounted on the battery compartment cover 12 through the first connector 13, and the second end is used to form an elastic pressing force on the battery pack 2. The second end of the spring sheet is generally in an outwardly convex arc-shaped structure, and when the battery compartment cover 12 and the shell body 11 are covered, the second end of the spring sheet has a pressing force on the battery pack 2 in the direction of the electrical connector 31, so that the battery pack 2 is tightly connected to the electrical connector 31.

[0055] For example, in order to facilitate the insertion and removal of the battery pack 2 in the battery compartment 3, a connected reserved space is formed in the battery compartment 3 near the battery compartment cover 12 and protrudes upward to facilitate the operator's operation.

[0056] For example, in this embodiment, the battery pack 2 is connected to the control circuit board 8 through the electrical connector 31, so that the battery pack 2 supplies power to the entire device through the control circuit board 8. For example, the control circuit board 8 is connected to the air pump assembly 6, buttons and sensors in the device, and the battery pack 2 supplies power to the air pump assembly 6, buttons and sensors through the electrical connector 31.

[0057] For example, Figure 3 , Fig.11 As shown, the air pump device of the present application also includes a charging interface 17, which is arranged in the shell and avoids the battery pack 2; the charging interface 17 is used to connect to the control circuit board 8. The charging interface 17 is a wired charging interface. The charging interface 17 is used to electrically connect to an external power line. The charging interface 17 is arranged toward the opening of the battery compartment cover 12, and the charging interface 17 is a certain distance away from the battery compartment cover 12 (the battery pack 2 protrudes a certain distance from the charging interface 17), which is convenient for the user to grab the battery pack 2 while facilitating the connection of the data line (power line). The charging interface 17 supplies power to the operation of the entire device through the control circuit board 8. For example, the charging interface 17 can be electrically connected to the air pump assembly 6, buttons and sensors through the control circuit board 8 to supply power to the operation of the air pump assembly 6, buttons and sensors.

[0058] The present application provides two different options for the working power supply of the entire device by setting up a battery pack 2 for power supply and a charging interface 17 for power supply. When using it, the user can choose one of the methods according to actual needs, which is simple and convenient.

[0059] Preferably, the air pump device further includes an electrical connector 31 and a charging interface 17 respectively connected to the control circuit board, the charging interface 17 is arranged in the battery compartment, and the charging interface 17 and the electrical connector 31 are plugged in the same direction, wherein:

[0060] Along the direction of the electrical connector 31 plugging the battery pack 2, the distance between the charging interface 17 and the electrical connector 31 is smaller than the length of the battery pack 2. When the battery pack 2 is plugged into the electrical connector 31, the battery pack 2 and the charging interface 17 are kept adjacent to each other, and the battery pack 2 protrudes from the charging interface 17. That is, when the battery compartment cover is opened, the upper and lower surfaces of the battery pack 2 located in the battery compartment 3 are partially exposed to the external space, so that the battery pack 2 can be grabbed, making it convenient for the user to disassemble the battery pack 2.

[0061] On the other hand, along the direction of the electrical connector 31 plugging the battery pack 2, the distance between the charging port 17 and the shaft bracket 5 is less than the distance that the battery pack 2 protrudes from the charging port 17. That is, the battery pack 2 protrudes from the charging port 17 and the shaft bracket 5.

[0062] More preferably, along the direction of the electrical connector 31 plugging into the battery pack 2 , the distance between the charging port 17 and the pivot bracket 5 is relatively small.

[0063] In one embodiment, the air pump device of the present application further includes a shaft bracket 5, the shaft bracket 5 is rotatably connected to the first end of the battery compartment cover 12, and the second end of the battery compartment cover 12 is detachably connected to the shell body 11; wherein the shaft bracket 5 is fixedly installed inside the shell body 11. In the present application, the shaft bracket 5 is built-in, making the overall appearance of the device more concise.

[0064] For example, Figure 3 , Figure 11-15 As shown, the rotating shaft bracket 5 includes a bracket main body 51, and the bracket main body 51 is fixedly connected to the shell body 11;

[0065] The hook portion 52 is formed on one side of the bracket body portion 51 . The hook portion 52 is buckled onto the connecting shaft 121 at the first end of the battery compartment cover 12 , so that the battery compartment cover 12 can rotate around the hook portion 52 .

[0066] For example, Figure 5 , Figure 8 As shown, the shell body 11 is enclosed by an upper shell 112 and a lower shell 113, and the upper shell 112 and the lower shell 113 are detachably fixedly connected, for example, they are fixedly connected by screws. The bracket body 51 is generally a flat rectangular structure, and a mounting hole 511 is formed in the bracket body 51. Connecting columns 111 extend outward from the inner wall surface of the lower shell 113 of the shell body 11 and the corresponding positions of the inner wall surface of the upper shell 112. The shape of the connecting column 111 is adapted to the mounting hole 511. When the upper shell 112 and the lower shell 113 are fixed, the connecting column 111 is passed through the mounting hole 511 to limit and fix the bracket body 51 in the shell body 11. In order to save the internal space of the shell, the bracket body 51 is arranged at the bottom of the shell body 11, that is, at the bottom of the battery compartment.

[0067] The hook portion 52 is generally a semicircular hook-shaped structure. The hook portion 52 is hooked on the connecting shaft 121 at the first end of the battery compartment cover 12 through its notch, and the battery compartment cover 12 below the connecting shaft 121 is provided with an escape opening 122 for avoiding the hook portion 52 .

[0068] like Figure 9-14 As shown, the second end of the battery compartment cover 12 is detachably connected to the housing body 11. Specifically, the battery compartment 12 is generally in an arc-shaped structure, and is enclosed together with the upper shell 112 and the lower shell 113 to form the housing 1 structure. The battery compartment cover 12 is arranged on one side of the battery compartment 3, and when the battery compartment cover 12 is opened, the battery pack 2 in the battery compartment can be exposed.

[0069] The battery compartment cover 12 is snap-connected to the lower shell 113 of the housing body through the snap assembly 14. Specifically, an open mounting groove 123 is provided at the second end of the battery compartment cover 12, and the snap assembly 14 is installed on the mounting groove 123. The snap assembly 14 includes a snap body 141 and a spring 142. The left and right sides of the snap body 141 are respectively provided with a slide groove 1411, and a slide rail 1231 adapted to the slide groove 1411 is provided at a corresponding position of the mounting groove 123 in the vertical direction. The snap body 141 is installed on the slide rail 1231 of the mounting groove through the slide groove, and the outer side surface of the snap body 141 is exposed outside the mounting groove. By manually toggling the snap body 141, the snap body can slide up and down in the mounting groove along the vertical direction.

[0070] A protruding engaging portion 1412 is formed on the top of the buckle body 141, and a slot 1131 adapted to the engaging portion 1412 is formed at a corresponding position of the lower shell 113. The bottom of the buckle body 141 is fixedly connected to the first end of the spring 142, and the second end of the spring 142 abuts against the mounting groove 123. In addition, since the first connecting member 13 is also installed on the battery compartment cover, the first connecting member 13 not only fixes the first end of the spring sheet, but also restricts the buckle assembly 14 in the mounting groove.

[0071] Therefore, when the battery compartment cover 12 needs to be opened, the buckle body 141 is pushed downward, and the spring 142 is compressed, so that the engaging portion 1412 is separated from the engaging slot 1131 of the lower shell 113, and the battery compartment cover 12 is rotated to rotate downward around the hook portion 52. When the battery compartment cover 12 needs to be closed with the housing body 11, the battery compartment cover is rotated until the engaging portion 1412 is close to the engaging slot of the lower shell, and the buckle body 141 is pushed downward to move the engaging portion 1412 downward to avoid the lower shell, so that the battery compartment cover and the lower shell are aligned, and the buckle body is released, so that the buckle body moves upward under the action of the spring, and the engaging portion 1412 is locked in the engaging slot 1131, and the battery compartment cover 12 is closed.

[0072] For example, Figure 5 , Figure 8 As shown, a first guide portion 1121 is provided on the inner wall surface of the upper shell 112, and a second guide portion 1132 is provided on the inner wall surface of the lower shell 113 at a position corresponding to the first guide portion 1121. Correspondingly, guide grooves 21 are respectively opened on both sides of the battery pack 2, and the guide grooves cooperate with the first guide portion and the second guide portion to guide the insertion and removal of the battery pack 2.

[0073] In one embodiment, Fig.15 As shown, the rotating shaft bracket 5 further includes a limiting protrusion 53, which is disposed behind the hook portion 52 and connected to the bracket body 51. The limiting protrusion 53 is used to limit the rotation range of the battery compartment cover.

[0074] like Fig.15 As shown, an opening slot 54 with openings on both sides is formed between the hook portion 52 and the bracket body 51, and a limiting protrusion 53 is provided on the opening slot 54 and extends downward. The limiting protrusion 53 can limit the rotation range of the battery compartment cover 12. Specifically, as Fig.11 As shown, when the battery compartment cover 12 rotates around the hook portion 52 to a certain angle, the edge of the battery compartment cover can abut against the limiting protrusion 53, and the limiting protrusion prevents the battery compartment cover from further rotating, limiting it to the maximum opening and closing angle, and keeping the battery compartment cover at the maximum rotation angle. Therefore, by providing the limiting protrusion 53, the present application can make the battery compartment cover easy to insert and remove the battery pack 2 when opened, and also avoid the battery compartment cover 12 from being damaged due to free fall due to gravity.

[0075] For example, the shaft bracket 5 is an integrally formed structure consisting of a bracket body 51, a hook portion 52 and a limiting protrusion 53. For example, the shaft bracket can be integrally formed by a mold, so that the shaft bracket is simple and convenient to manufacture and maintains a certain strength.

[0076] In one embodiment, Figure 3 As shown, the air pump device of the present application also includes an air pump assembly 6, which is used for providing a pluggable battery compartment 3 for the battery pack 2. The battery compartment 3 is formed in the shell 1 along the horizontal direction, and the battery compartment 3 is away from and arranged along the axial direction of the output end of the air pump assembly 6.

[0077] In the air pump device of the present application, the battery compartment 3 is formed in the shell in the horizontal direction (lateral direction) and is arranged away from the air pump assembly 6, and the battery compartment 3 is arranged along the axial direction of the output end of the air pump assembly, so that the lateral width of the air pump device is reduced and the wiring of the air pump assembly is convenient. In addition, because the air pump assembly 6 and the battery compartment 3 are arranged along the axial direction of the air pump assembly, the lateral width of the output end of the air pump device only needs to be designed according to the spacing between the first air inlet and the output port of the air pump assembly, so that compared with the current air pump device, the lateral width of the output end face of the air pump device of the present application (the first air inlet 611 and the output port 621 are collectively referred to as the output end, and the shell end face where the output end is located is named the output end face) is further reduced, so that the constraint of the filling / discharging port of the object to be filled / discharged is small, especially for some scenes where the filling / discharging port of the object to be filled / discharged is affected by other surrounding components, resulting in a small space left around the filling / discharging port. The output end face of the air pump device of the present application has a smaller lateral width, which enables the device to operate more flexibly.

[0078] Further, such as Figure 3-5As shown, the air pump assembly 6 has a first air inlet 611 and an outlet 621. The first air inlet 611 and the outlet 621 are arranged on the same side and away from the battery compartment, and the distance between the two is 50% to 80% of the horizontal width of the battery compartment.

[0079] The first air inlet 611 and the outlet 621 are arranged on the same side and away from the battery compartment 3. The battery compartment 3 and the first air inlet 611 and the outlet 621 are kept on opposite sides of the air pump assembly 6, which can improve the operation flexibility of the device. The spacing between the first air inlet 611 and the outlet 621 of the air pump assembly is small, only 50% to 80% of the horizontal width of the battery compartment, so that the end face of the output end of the device is also reduced, which can make the device more flexible in charging / discharging operations.

[0080] For example, Figure 3-5 As shown, the air pump assembly 6 includes a first air pump 61, and the first air pump 61 has a first air inlet 611 and an air outlet 612;

[0081] The second air pump 62 has a second air inlet, an outlet 621 and an output branch 622 communicating with the outlet 621 . The output branch 622 is communicated with the air outlet 612 via a one-way valve.

[0082] For example, the first air pump is a low-pressure centrifugal pump, and the second air pump is a high-pressure plunger pump. The low-pressure centrifugal pump is an air pump that can be used for both charging and discharging. The low-pressure centrifugal pump has a high flow rate but low pressure, and the high-pressure plunger pump has a high pressure but low flow rate. This application connects the two, and the inflation can be faster and more efficient in the dual-pump mode. For example, when the inflatable object is inflated, the output port 621 can be connected to the inflation interface of the inflatable object, and the first air inlet 611 of the low-pressure centrifugal pump inhales outside air and flows to the output port 621 through a one-way valve to inflate the inflatable object quickly. The high-pressure plunger pump works at the same time, inhaling outside air from the second air inlet and inflating the inflatable object quickly through the output port 621. Therefore, when inflating, this application can adopt a dual-pump mode, and the dual pumps work at the same time, so that the object can be quickly filled with air, and when the high-pressure plunger pump works, the inflatable object can reach a set pressure value. The inflation time is faster and more efficient in the dual-pump mode.

[0083] When the device of the present application is used to quickly deflate the object to be deflated, the second air pump does not work, and only the first air pump works. The first air inlet is connected to the deflation interface of the object to be deflated, and the first air pump (centrifugal pump) works to quickly pump out the gas in the object to be deflated and discharge the gas through the output port 621.

[0084] For example, Figure 4-5 , Figure 8As shown, the air pump device of the present application also includes an air pump compartment 7 for accommodating the air pump assembly, and the air pump compartment 7 and the battery compartment 3 are formed in the shell 1 and are separated and arranged in the upper and lower directions along the vertical direction. Specifically, the shell 1 can separate the air pump compartment and the battery compartment in the following manner: the inner wall surface of the upper shell 112 of the shell body 1 is horizontally connected with a first partition plate 15, and the first partition plate 15 divides the upper shell 112 into two parts, and the inner wall surface of the lower shell 113 is correspondingly horizontally connected with a second partition plate 16, and the second partition plate 16 divides the lower shell 113 into two parts, and when the upper shell 112 and the lower shell 113 are fixed, the first partition plate and the second partition plate are aligned, so that the upper shell / lower shell, the first partition plate 15, and the second partition plate 16 of the upper half are enclosed to form the air pump compartment 7, and the air pump assembly 6 is installed in the air pump compartment 7. The upper shell / lower shell, the first partition plate and the second partition plate and the battery compartment cover of the lower half are enclosed to form a battery compartment 3, in which the battery pack 2 can be placed, so that the axial direction of the battery pack and the direction of the dual air pump output are arranged perpendicularly. Among them, the first air inlet 611 and the outlet 621 of the air pump assembly 6 are exposed outside the shell 1. Among them, the charging interface 17 is installed on the first partition plate 15 and the second partition plate 16. When the upper shell and the lower shell are fixed, the charging interface 17 is arranged toward the battery compartment cover 12, and the charging interface 17 is located above the battery pack 2 to avoid the battery pack 2.

[0085] In one embodiment, Figure 1 , Figure 5 , Figure 8 As shown, the air pump device of the present application also includes a control circuit board 8 and a button 9. The control circuit board 8 is arranged in the shell, and the control circuit board 8 is electrically connected to the air pump assembly 6; the button 9 is connected to the control circuit board 8, and the button 9 is used to output an adjustment signal to the control circuit board, and the control circuit board 8 adjusts the output power of the air pump assembly according to the adjustment signal.

[0086] like Figure 5 , Figure 8 As shown, in this embodiment, the control circuit board 8 is installed on the inner wall of the upper shell 112 and retained on the radial side of the air pump assembly 6. The control circuit board 8 and the air pump assembly 6 are placed together in the air pump compartment 7 and are maintained at a distance from the battery compartment 3.

[0087] In this embodiment, the button 9 is arranged on the outer surface of the upper shell 112 and is connected to the control circuit board 8. The button 9 is used to output an adjustment signal to the control circuit board 8, and the control circuit board 8 adjusts the output power of the air pump assembly 6 according to the adjustment signal.

[0088] For example, the purpose of adjusting the output power can be achieved by controlling the output pressure of the second air pump. Specifically, an air pressure sensor is provided in the housing body 11 and near the output port 621. The air pressure sensor is used to detect the air pressure value of the gas output from the output port 621 in real time and transmit it to the control circuit board. Therefore, when it is necessary to adjust the output pressure of the air pump assembly, the control circuit board receives and determines the predetermined pressure value transmitted by the button 9, and after comparing it with the air pressure value received in real time, adjusts the output air pressure of the second air pump, thereby achieving the purpose of adjusting the output power of the air pump assembly.

[0089] Alternatively, the output power of the air pump assembly can be adjusted by adjusting the gas flow rate of the output port 621 of the air pump assembly 6. Specifically, an air flow sensor is provided in the housing body 11 and near the output port 621, and the air flow sensor is used to detect the air flow value of the gas output from the output port 621 in real time and transmit it to the control circuit board 8. Therefore, when it is necessary to adjust the output flow rate of the air pump assembly, the control circuit board receives and determines the predetermined flow value delivered by the key, and after comparing it with the air flow value received in real time, controls and adjusts the gas flow rates of the first air pump and the second air pump, so that the output gas of the air pump assembly reaches the predetermined flow value, thereby achieving the purpose of adjusting the output power of the air pump assembly.

[0090] In the present application, by setting the button 9, dust or water can be prevented from entering the device, thereby effectively maintaining the normal operation of the device.

[0091] Of course, the button 9 can also be replaced by a roller, which is connected to the control circuit board through a position encoder, and the output power of the air pump assembly can be adjusted by rolling the roller. In order to prevent sand and dust from entering the device, a sealing ring can also be added to the roller shaft to prevent sand and dust from entering.

[0097] Along the direction of the electrical connector 31 plugging the battery pack 2, the distance between the charging port 17 and the rotating shaft bracket 5 is smaller than the distance that the battery pack 2 protrudes from the charging port 17.
