Description

Technical Field

[0001] This disclosure relates to the field of air pump technology, and more particularly to air pump devices and air pump modules. Background Technology

[0002] Traditional electric air pumps typically only have a unidirectional inflation function. To deflate, they rely on an external manual exhaust valve or a separate pumping system, resulting in inconvenience and low efficiency. Some products with bidirectional airflow control rely on complex solenoid valves or multi-channel switching systems, which suffer from numerous parts, high failure rates, poor airtightness, and high costs.

[0003] In addition, the core components of the air pump in the current products (air pump assembly, reversing assembly, valve assembly, etc.) are often assembled in a decentralized manner, which makes the assembly process complex, maintenance difficult, and sealing failures easy to occur in vibration environments.

[0004] As users demand more multifunctional and intelligent operation, the number of air pump parts that need to be assembled will continue to increase, which will greatly affect assembly efficiency. Therefore, there is an urgent need for a new type of electric air pump solution that is highly integrated in structure, reliable in operation, and quick in switching. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this disclosure is to provide an air pump device and an air pump module to solve the problem that the large number of parts to be assembled in the air pump affects the assembly efficiency in the related art.

[0007] In an embodiment of the first aspect, the air pump unit includes: an air pump housing, in which the air guide cavity is formed, and the air intake port and the air exhaust port are arranged at intervals on a surface; the surface is adjacent to the wall of the pump housing where the second air vent is located, so that it can be moved relative to the second air vent to make the air intake port or the air exhaust port communicate with the second air vent; and an air pump body, which is fixedly disposed in the air guide cavity.

[0008] In a first aspect embodiment, the air pump module further includes a driven part integrally connected to the air pump unit, and the guiding mechanism includes: a driver fixed to the receiving cavity and a driving part driven by it, the driving part being movably connected to the driven part; or, the air pump module further includes: a driver integrally connected to the air pump unit and a driving part driven by it; the guiding mechanism includes: a driven part fixed to the receiving cavity.

[0009] In an embodiment of the first aspect, the driver is implemented as a drive motor, the driving part is driven to rotate by the drive motor, and the driving part and the driven part constitute a transmission mechanism that converts rotational motion into linear motion; or, the driver drives the driving part in a linear motion manner.

[0010] In an embodiment of the first aspect, the driving part includes a gear, and the driven part includes a rack; or, the driving part includes a screw, and the driven part includes a nut; or, the driving part includes a telescopic member that is retractable along the moving direction, and the driven part includes a connecting part connected to the telescopic member.

[0011] In an embodiment of the first aspect, the pump housing exposes an operating component, and the receiving cavity contains at least one circuit board that operates in conjunction with the operating component, one of the circuit boards being a control circuit board electrically connected to and controlling a driver that provides power for the movement of the air pump module.

[0012] In a first aspect embodiment, the receiving cavity forms a bearing surface corresponding to the position of the air pump module. The bearing surface is provided with the second air vent and a cavity structure. The cavity structure is connected to the first air vent. When one of the exhaust port and the extraction port is connected to the second air vent, the cavity structure is connected to the other of the exhaust port and the extraction port, forming a positive / reverse airflow path between the first air vent and the second air vent through the air guide cavity and the cavity structure.

[0013] In an embodiment of the first aspect, the air pump device includes: a limiting component, fixedly disposed in a receiving cavity and having a through gap, and spaced apart from the inner wall of the receiving cavity to form a limiting space communicating with the through gap; the air pump module passes through the through gap and is contained in the limiting space in a limiting manner, and is guided in its direction of movement by the limiting space.

[0014] In an embodiment of the first aspect, the air pump device includes: a position sensor disposed in the receiving cavity, corresponding to a predetermined position during the movement of the air pump module, for cooperating with a detection part on the air pump device that reaches the predetermined position to generate a signal indicating that the air pump module has moved to a first position that disconnects the airflow path; a circuit board electrically connected to the position sensor, the air pump unit, and the driver; the driver providing power for the movement of the air pump module.

[0015] A second aspect of this disclosure provides an air pump module movably disposed in an air pump device, comprising: an air pump unit including an air guide chamber and an air intake port and an exhaust port connected thereto, allowing the connection between the air intake port and the exhaust port and two air inlets of the air pump device to be switched at different locations reached by the movable device, so as to open or close airflow paths in different directions between the two air inlets.

This disclosure innovatively provides a modular air pump module, which can be moved to different positions to switch between charging and discharging, and has advantages such as high modularity, easy assembly, simple air path switching, good sealing performance, and integrated charging and discharging connection.

[0017] The disclosed air pump device, on the one hand, breaks through the traditional structure that relies on valves to switch air paths, but instead treats the air pump module as a movable unit, using drive transmission to change its position and guide the airflow path for charging / discharging. It features high integration, eliminating complex components such as multi-channel connectors, simplifying the internal structure, supporting complete replacement, and significantly reducing maintenance difficulty. At the same time, due to the shortened flow path and low resistance, it increases the effective airflow per unit time.

[0018] On the other hand, a combination of planar sealing and sliding sealing can be used to improve sealing reliability.

[0019] On the other hand, the power cord can be hidden in the cover, making it neat and beautiful, suitable for use in various scenarios such as home, car, and outdoors. Attached Figure Description

[0046] Currently, the core components of the air pump in the product (air pump assembly, reversing assembly, valve assembly, etc.) are often assembled in a decentralized manner, which makes the assembly process complex, maintenance difficult, and prone to sealing failure in vibration environments.

[0047] As users demand more multifunctional and intelligent operation, the number of air pump parts that need to be assembled will continue to increase, which will greatly affect assembly efficiency. Therefore, there is an urgent need for a new type of electric air pump solution that is highly integrated in structure, reliable in operation, and quick in switching.

[0048] In view of this, the present disclosure provides an air pump device that adopts an integrated modular design of air pump module. By driving the movement of the air pump module, bidirectional inflation / deflation is achieved. It is easy to assemble and can reuse the air inlet to achieve inflation / deflation. The structure is simple and solves the problems in related technologies.

[0049] Please see Figure 1 and Figure 2 . Figure 1 A schematic diagram of the overall structure of the air pump device in one view of an embodiment of this disclosure is shown. Figure 2 A schematic diagram of the overall structure of the air pump device from another perspective.

[0050] The air pump device 100 includes a pump housing 110. The pump housing 110 is provided with a receiving cavity 1100 (see...). Figure 3 The pump housing 1100 includes a first vent 1101 and a second vent 1102 connected to it. The receiving cavity 1100 is located inside the pump housing 110. Figure 1 In this design, the first vent 1101 is located at the top of the pump housing 110. As an example, the first vent 1101 may be provided with a grille structure. On one hand, the grille structure can protect the interior of the pump housing 110 while allowing ventilation, preventing foreign objects from falling in or users from touching internal components. On the other hand, the grille structure can also fill the first vent 1101 to form an aesthetically pleasing, flat structure. Figure 2 The second vent 1102 is shown in the diagram, and it may be exemplarily located at the bottom of the pump housing 110. Optionally, the periphery of the second vent 1102 on the outward side may also be fixedly covered with a cage or fence structure to form a protective function.

[0051] Exemplarily, the pump housing 110 exposes an operating component 120, which may be located on the top of the pump housing 110. The operating component 120 may be implemented as a button (such as an inflation button, an deflation button), etc., but is not limited thereto. Exemplarily, the air pump device 100 may have a power cord 154 for connecting to an external power source, and the top of the pump housing 110 may also be provided with a wire groove 1112 to embed and accommodate the power cord 154, which is neat, aesthetically pleasing, and space-saving.

[0052] You can refer to them together. Figure 3As shown, to facilitate the installation of internal components, the pump housing 110 may include an upper and lower jointed face cover 1110 and a bottom shell 1120, which together form the receiving cavity 1100. In some examples, the face cover 1110 and the bottom shell 1120 can be fixedly connected by a snap-fit ​​method, such as a snap-fit ​​structure between their mating edges, to achieve screwless fixing. Alternatively, in other embodiments, the face cover 1110 and the bottom shell 1120 can also be fixedly connected by screws. Of course, the snap-fit ​​connection method is more convenient.

[0053] exist Figure 3 The image, by way of example, illustrates an air pump module 130 disposed in a receiving cavity 1100 and a guide mechanism 140 that moves in conjunction with it. The air pump module 130 is movably disposed in the receiving cavity 1100 so as to move to different positions to facilitate the inflation and deflation path between the first air inlet 1101 and the second air inlet 1102. Figure 3 The image also shows a second circuit board 152 in the air pump device 100, which is electrically connected to the power line 154. As an example, the movement can be linear, such as sliding along a straight or curved trajectory.

[0054] Further as Figure 4 As shown, an exemplary demonstration Figure 3 A further disassembled structural diagram of the middle cover 1110 and its connected components.

[0055] exist Figure 4 Optionally, the air pump device 100 may further include at least one circuit board that operates in conjunction with the control component 120. The receiving cavity 1100 contains at least one circuit board that operates in conjunction with the control component 120. Operational conjunction means that the control component is manipulated, triggering the function control of the circuit board. For example, the figure shows a first circuit board 151 and a second circuit board 152 arranged vertically. As an example, the first circuit board 151 may be a button circuit board that operates in conjunction with a button, and may be equipped with a microswitch that can be triggered by pressing a button to generate a corresponding button signal output. The second circuit board 152 is electrically connected to the first circuit board 151. The second circuit board 152 may be implemented as a control circuit board, which can generate control signal outputs for the corresponding charging / discharging function of the air pump device 100 based on the button signal.

[0056] In some embodiments, the bottom surface of the cover 1110 may extend out with multiple mounting members (such as threaded post holes) for fixing the first circuit board 151 and the second circuit board 152. As an optional example, the first circuit board 151 can be directly fixed to the mounting member (e.g., with screws). As an optional example, the second circuit board 152 can be snapped into a mounting bracket 153, which is fixedly connected to the mounting member (e.g., with screws). The power cord 154 is electrically connected to the second circuit board 152 and spirals upwards through the through-hole 1111 of the cover 1110 into the communicating wire groove 1112, and can be removed from the wire groove 1112. Optionally, the inner wall of the wire groove 1112 may be provided with a latching element, such as spaced elastic protrusions, to hold the power cord 154 in place, preventing it from falling off or tangling. Placing the power cord 154 on the surface of the cover 1110 makes it easier to carry, avoids tangling, and makes operation more convenient, and is also more suitable for use in scenarios with limited space, such as vehicle-mounted inflatable devices.

[0057] Optionally, to restrict the movement of the power cord 154 leading out from the second circuit board 152, the through hole 1111 may be located in the wire hole post 1113 extending downward from the cover 1110. Further optionally, a notch may be formed at the lower end of the wire hole post 1113, and a wire retainer 155 may be provided at the notch. The first arc-shaped groove of the wire retainer 155 and the second arc-shaped groove at the lower end of the wire hole post 1113 together form a circular opening to restrict the power cord 154. For example, it can be used to clamp and fix the power cord 154. As an example, the wire retainer 155 may also be fixedly connected to the cover 1110 by a mounting member (e.g., fixed with a stud screw).

[0058] One of the air pump module 130 and the guide mechanism 140 may include a driver to provide a driving force for moving the air pump module 130 in the direction guided by the guide mechanism 140.

[0059] like Figure 5 , Figure 6 , Figure 7 and Figure 8 The diagram illustrates the structure of the air pump module 130. Figure 5 A schematic diagram of the air pump module 130 in an embodiment of this disclosure is shown from one perspective. Figure 6 A structural schematic diagram of the air pump module 130 from another perspective. Figure 7 An exploded view of the air pump module 130 is shown. Figure 8 A cross-sectional view of the air pump module 130 is shown.

[0060] The air pump module 130 is movably disposed within the receiving cavity 1100. The movement trajectory of the air pump module 130 can be a straight line or a curve. As an example, the receiving cavity 1100 is rectangular, and its length direction (e.g., Figure 4 The direction of arrow A is defined as the direction of movement of the air pump module 130. The air pump module 130 can move linearly along its length within the receiving cavity 1100.

[0061] exist Figure 6 In the middle, the air pump unit 131 includes an air intake port 1311, an exhaust port 1312, and an air guide chamber 1313 communicating between them (see Figure 8 (As shown). The suction port 1311 and exhaust port 1312 are respectively designed to communicate with the second vent when the air pump module 130 moves to different positions. Therefore, the arrangement of the suction port 1311 and exhaust port 1312 is coordinated with the movement of the air pump module 130. For example, in this embodiment, the air pump module 130 can move along the length of the receiving cavity, and the suction port 1311 and exhaust port 1312 are located on the bottom surface of the air pump unit 131 and arranged along the length direction.

[0062] exist Figure 7The air pump unit 131 may further include an air pump upper cover 1314, an air pump motor 1315, a motor bracket 1316, an impeller 1317, and an air pump lower cover 1318. The air pump upper cover 1314 may have a connecting cavity with two downwardly open ends. The air pump lower cover 1318 is designed for a sealed connection with the air pump upper cover 1314. The top of the air pump lower cover 1318 has a suction chamber 13181 and an exhaust chamber 13182, which are respectively sealed and connected to the two open ends of the connecting cavity. Specifically, the suction chamber 13181 and the exhaust chamber 13182 may be recessed and respectively incorporated into the downwardly opening ends of the air pump upper cover 1314 to form a connection. The suction chamber 13181 communicates with its lower suction port 1311, and the exhaust chamber 13182 communicates with its lower exhaust port 1312. Therefore, when the upper cover 1314 and the lower cover 1318 of the air pump are sealed together, connecting the suction chamber 13181, the exhaust chamber 13182, and the connecting chamber, a guide chamber 1313 connecting the suction port and the exhaust port 1312 can be constructed. The air pump motor 1315, the motor bracket 1316, and the impeller 1317 can be arranged coaxially in sequence. The air pump motor 1315 is fixed to the motor bracket 1316, and its output shaft passes through the central hole of the motor bracket 1316 and is fixedly connected to the center of the impeller 1317 to drive the impeller 1317 to rotate, thereby forming an airflow from the suction port 1311 through the guide chamber 1313 to the exhaust port 1312. The air pump motor 1315, the motor bracket 1316, and the impeller 1317 are shaped to fit into the communicating space between the suction chamber 13181 and one of the corresponding open ends of the air pump upper cover 1314. Specifically, the suction chamber 13181 and its corresponding open end can be cylindrical, and the air pump motor 1315, motor bracket 1316, and impeller 1317 are also cylindrical in shape. As an example, the periphery of the open end of the air pump cover 1314 can be formed with an annular groove 13151 with an opening facing downward (formed in the gap between the sub-cylinders of the air pump cover 1314 corresponding to the suction port 1311 and the exhaust port 1312 respectively), so as to fit and press the motor bracket 1316 onto the lower cover 1318 of the air pump to fix the motor bracket 1316 and the air pump motor 1315.

[0063] exist Figure 8 The image exemplarily illustrates the path of airflow from the intake port 1311 to the exhaust port 1312 when the air pump motor 1315 is operating, driving the impeller 1317 to rotate.

[0064] In this embodiment, optionally, the air pump module 130 includes a driven portion 132 integrally connected to the air pump unit 131. In this embodiment, the driven portion 132 is implemented as a rack for meshing with the gear of the guide mechanism 140. When the gear rotates, it travels along the rack, causing relative movement of the air pump module 130. Exemplarily, the lower cover 1318 of the air pump is provided with a groove 13183 into which the gear can be accommodated. The rack is located on one side of the groove 13183 and can extend along the groove 13183. When the air pump module 130 is installed into the receiving cavity 1100, it is configured such that the groove 13183 is aligned with the direction of movement (i.e., in example, the length direction of the receiving cavity 1100).

[0065] like Figure 9 The present invention provides a schematic diagram of the structure of the guide mechanism 140 in an embodiment of the present disclosure.

[0066] Alternatively, in this embodiment, the guide mechanism 140 can be implemented as a modular drive module for easy assembly.

[0067] Exemplarily, the guiding mechanism 140 may include a driver 141 and a driving part 142 connected to it. The driver 141 may be implemented as a drive motor. The driver 141 may be fixed in the receiving cavity 1100, for example, by snap-fit, screw locking, etc. The driver 141 may be fixed in the receiving cavity 1100, for example, fixed to a cavity wall such as a side wall or bottom wall. For example, the housing of the driver 141 may extend radially with a plurality of ears with mounting holes to correspond to the screw holes extending from the cavity wall of the receiving cavity 1100 to form a screw lock. Alternatively, a snap-fit ​​method may be used, and it is not limited thereto. In this embodiment, the driving part 142 may be implemented as a gear, which may be connected to the output shaft of the driver 141 to be driven to rotate. The gear meshes with the driven part 132, which is implemented as a rack. When the gear rotates, it can move relative to the rack.

[0068] The height of the gear can be higher than the height of the slide groove 13183, so that the driver 141 can maintain a certain distance from the slide groove 13183 to avoid interference.

[0069] It is worth mentioning that, in some other embodiments, the drive module can also be integrated into the air pump module 130, integrally connected with the air pump unit 131, and movable together. In this case, the guide mechanism 140 can be implemented as including a driven part 132, fixed to the receiving cavity 1100. Specifically, the lower cover of the air pump unit 131 may have a portion for mounting the drive module, such as a mounting surface or a recess. The drive module can be fixed upright or inverted (e.g., by snap-fit ​​or screw-locking) at this portion, keeping its drive part 142 exposed and aligned with the driven part 132. The driven part 132 is fixed to the cavity wall of the receiving cavity 1100, allowing for relative movement. In a specific application example, the drive module can be fixedly installed at the end of the lower cover away from the main body of the air pump unit 131 (for example, the end near the rack in the figure). The driver 141 is fixed above the lower cover, and its output shaft passes through the lower cover to its bottom and is connected to the drive part 142 (such as a gear). In this embodiment, the rack, which serves as the guide mechanism 140, can be fixed at the position where the side wall of the receiving cavity 1100 is adapted to the height of the gear and combined.

[0070] In other embodiments, the guide mechanism 140 may also include a telescopic member, which is restricted to telescoping along the direction of movement, and the air pump unit 131 is connected to the telescopic member to move with it. Specifically, the guide mechanism 140 may be implemented as a cylinder, fixed in the receiving cavity 1100, and its piston is fixedly connected as a telescopic member to the connecting portion of the air pump unit 131, which is the driven part 141. In this embodiment, the air pump module 130 may only include the air pump unit 131, without including the driven part 141.

[0071] Therefore, the specific integrated structure of the air pump module 130 can vary and is not limited to the diagram shown.

[0072] It is understood that the movement is linear, along a straight line or curve, while the output shaft of the drive 141, which serves as its power source, rotates. Therefore, a transmission mechanism is required between the driving part 142 and the driven part 141 to convert rotational motion into linear movement.

[0073] In some examples, the driving part 142 and the driven part 132 can form a transmission mechanism that converts rotational motion into linear motion, such as the gear and rack transmission mechanism shown in the figure. Of course, this implementation is not limited to this; the transmission mechanism can also be a threaded connection mechanism. For example, if the driving part 142 is a screw and the driven part 132 is a nut threadedly fitted onto the screw, then the driver 141 drives the screw to rotate.

[0074] In other examples, the driver 141 can also be connected to and drive the driving part 142 by a transmission mechanism that converts rotational motion into linear motion. In this case, the driving part 142 and the driven part 132 can be directly selected as structures that can undergo relative linear motion, such as sliders and slide rails / grooves, without having to use transmission mechanisms that convert rotation to linear motion, such as threads or gear meshing.

[0075] It is also worth mentioning that, in this embodiment, as Figure 4 As shown, the first circuit board 151, the second circuit board 152, and the guide mechanism 140 are positioned on both sides of the air pump module 130 along the length of the receiving cavity 1100, resulting in a balanced layout of components within the receiving cavity 1100. However, in other embodiments, the first circuit board 151, the second circuit board 152, and the guide mechanism 140 can also be arranged vertically on the same side of the air pump module 130 to reduce the space occupied, adapting to scenarios where the air pump device 100 needs to be smaller and more compact.

[0076] Please refer to Figure 10 and Figure 11 ,like Figure 10 The diagram illustrates the structure of the air pump module 130 and the guide mechanism 140 disposed in the receiving cavity 1100 according to an embodiment of this disclosure. Figure 11 The diagram shows a cross-sectional view of the air pump module 130 being fixed in the receiving cavity 1100.

[0077] Can be combined Figure 3 , Figure 4As shown, the air pump module 130 can be fixed in the receiving cavity 1100 by a limiting component 160. A limiting space is formed between the limiting component 160 and the opposing inner wall of the receiving cavity 1100. Specifically, the limiting component 160 can abut against an upper surface of the air pump module 130 to confine it within the limiting space between the limiting component 160 and its opposing wall surface (e.g., the bottom surface) of the receiving cavity 1100. For example, the limiting component 160 can abut against the protruding edge of the lower cover of the air pump module 130. Specifically, the limiting component 160 includes a pair of limiting members 161, which abut against the protruding edges of the lower cover 1318 of the air pump module 130 on both sides. The limiting component 160 has a through gap communicating with the limiting space, which can be formed by the gap between the pair of limiting members 161, allowing the air pump module 130 to partially pass through. Exemplarily, the upper cover 1314 of the air pump module 130 passes through the through gap and is fixedly spliced ​​with the lower cover 1318. The bottom of the air pump module 130 (the bottom of the lower cover) can be embedded in a groove provided on the bottom wall of the receiving cavity 1100 that matches the gap. In some embodiments, the limiting component 160 can be fixed to the inner wall of the receiving cavity 1100 by screwing. For example, the bottom of the two opposite side walls of the receiving cavity 1100 extending along the length direction are respectively formed with protrusions, and the upper surface of the protrusions is provided with screw holes. A pair of limiting members 161 are respectively placed on one protrusion, and the mounting holes 1611 thereon can correspond to the positions of the screw holes so that screws can be fastened to fix the limiting members 161 to the two side walls of the receiving cavity 1100. In other embodiments, the limiting component 160 can also be fixed to the inner wall of the receiving cavity 1100 by a snap-fit ​​structure, and is not limited to the illustration. To facilitate positioning and alignment for installing the limiting member 161, a positioning mechanism with a concave-convex fit can also be provided between the boss and the limiting member 161. Figure 12 The image shows a boss with a notch 1105, but in other embodiments it can also be a protrusion, and is not limited thereto.

[0078] Thus, the air pump module 130 is restricted to move within the limiting space. The limiting space can restrict the air pump module 130 in the depth direction of the receiving cavity 1100 and in other lateral directions besides the direction of movement (e.g., if the direction of movement is the length direction of the receiving cavity 1100, then the other lateral directions can be the width direction), guiding the air pump module 130 to move only along the specified direction of movement. Specifically, the bottom surface of the air pump module 130 can be embedded in a groove in the bottom wall of the receiving cavity 1100, and the extension direction of the groove in the bottom wall of the receiving cavity 1100 accommodating the air pump module 130 and / or the through gap can be consistent with the direction of movement (e.g., the length direction of the receiving cavity 1100 as indicated by arrow A). Preferably, when the air pump module 130 moves in the moving direction, the lower cover of the air pump module 130 can be constrained by the vertical and horizontal bidirectional constraints of the bottom wall (below) of the receiving cavity 1100 and the limiting member 161 (above), ensuring that the air pump module 130 can only move in the horizontal moving direction specified by the constraint. This can significantly improve the stability of the air pump module 130 during the moving process.

[0079] The second vent 1102 can be connected to the inflatable object, and the first vent 1101 can be connected to the outside environment (such as the atmosphere). Inflating refers to drawing gas in through the first vent 1101 and filling the inflatable object through the second vent 1102, thereby inflating the inflatable object. Deflating refers to extracting gas from the inflatable object through the second vent 1102 and releasing it to the outside environment through the first vent 1101, thereby deflating the inflatable object.

[0080] Please see Figure 12 , Figure 13 , Figure 14 and Figure 15 This is used to explain the principle of how the movement of the air pump module 130 enables the connection of the charging and discharging paths.

[0081] The receiving cavity 1100 of the pump housing has a bearing surface on the side corresponding to the position of the air pump module. In the figure, the bearing surface is an example of the inner bottom wall surface in the bottom shell 1120. Figure 12A schematic diagram of the inner bottom wall structure of the bottom shell 1120 in this embodiment is shown. The inner bottom wall of the bottom shell 1120 forms a bearing surface 1121 that matches the shape of the bottom surface of the air pump module 130. The bearing surface 1121 is provided with the second vent 1102 and cavity structures corresponding to the exhaust port 1312 and the suction port 1311 of the air pump module 130, respectively. The cavity structures can communicate with the first vent 1101. When one of the exhaust port 1312 and the suction port 1311 is connected to the second vent 1102 (a sealed connection can be achieved through the compressed sealing ring 1103), the cavity structure can communicate with the other of the exhaust port 1312 and the intake port, thereby forming a forward / reverse airflow path between the first vent 1101 and the second vent 1102 through the air guide cavity 1313 and the cavity structure.

[0082] exist Figure 12 In the example, the cavity structure includes a first recess 1122 and a second recess 1123. The first recess 1122 and the second recess 1123 may be formed by recesses on opposite sides of the bearing surface of the portion of the cavity 1100 adjacent to the inner end of the second vent 1102. The first recess 1122, the second vent 1102 and the second recess 1123 are arranged along the moving direction.

[0083] For example, the bottom wall of the pump housing 110 (i.e., the bottom wall of the receiving cavity 1100) is provided with a groove on the outer periphery of the second vent 1102, and a sealing ring 1103 can be embedded in the groove. Figure 3 , Figure 4 (Also shown in the image), the sealing ring 1103 can be kept in a state of being clamped and compressed by the air pump module 130 and the inner bottom wall of the pump housing 110, thereby maintaining the sealed connection between the second air vent 1102 and the air pump module 130.

[0084] exist Figure 13 In the first position, the air pump module 130 is closed by the bearing surface 1121 of the bottom wall of the receiving cavity 1100. At this time, the airflow path between the first vent 1101 and the second vent 1102 is disconnected, and the air pump device 100 does not perform the charging / discharging action. Specifically, the bearing surface 1121, which is relatively protruding between the first recess 1122 and the second recess 1123, abuts against the bottom surface of the air pump module 130, and its size is sufficient to cover and close the air intake port 1311 and the exhaust port 1312, cutting off the airflow path.

[0085] exist Figure 14In this configuration, when inflation is required, the user can operate the control component 120, such as by pressing the "inflate button". The second circuit board 152 controls the start of the electric pump motor 1315 and the driver 141 (in this embodiment, a drive motor). The air pump motor 1315 drives the impeller 1317 to rotate, generating airflow. The driver 141 rotates forward, driving the gear-rack mechanism to move the air pump module 130. Specifically, as shown... Figure 14 The device moves from the first position (in the example, to the left) to the second position. At this time, the suction port 1311 connects to the first recess 1122 to the first vent 1101, and the exhaust port 1312 connects to the second vent 1102. External airflow enters the inflatable material via the first vent 1101 → first recess 1122 → suction port 1311 → air guide chamber 1313 → exhaust port 1312 → second vent 1102. Simultaneously, the exhaust port 1312 and the second vent 1102 are sealed together. Optionally, the diameter of the exhaust port 1312 is smaller than that of the second vent 1102, allowing it to be compressed and sealed with the sealing ring 1103 on the outer periphery of the second vent 1102 and the bottom bearing surface 1121 of the air pump lower cover 1318, ensuring airtightness during inflation and enabling smooth and efficient inflation output.

[0086] exist Figure 15 In this system, when it is necessary to deflate the inflated object, the user can operate the control component 120, such as by pressing the "deflate button". The electric pump motor 1315 and the driver 141 are started by the second circuit board 152. The air pump motor 1315 drives the impeller 1317 to rotate, generating airflow (which can be reversed or maintain the original direction, depending on the design of the impeller 1317). The driver 141 reverses direction, pushing the air pump module 130 to move in the opposite direction (in this example, to the right) to the third position. At this time, the suction port 1311 is connected to the second vent 1102, and the exhaust port 1312 is connected to the first vent 1101 via the second recess 1123. The gas in the inflated object is discharged to the outside through the second vent 1102 → suction port 1311 → air guide chamber 1313 → exhaust port 1312 → second recess 1123 → first vent 1101. The suction port 1311 and the second vent 1102 can be sealed together. Specifically, the diameter of the suction port 1311 is smaller than that of the second vent 1102. It can be used to compress and seal with the sealing ring 1103 on the outer periphery of the second vent 1102 and the bearing surface 1121 on the bottom of the air pump cover 1318 to ensure air tightness during the venting process, so that the venting is smooth and efficient.

[0087] After deflation or inflation is complete, the actuator 141 can be reversed and reset to restore the air pump module 130 to its original state. Figure 13 The first position in the process is to cut off the inflation / deflation path.

[0088] In some embodiments, the driver 141 can drive the air pump module 130 to move according to a preset stroke, so that the moving module accurately reciprocates between a first position and a second or third position, thereby triggering the air pump motor 1315 and the driver 141 to cooperate in completing the charging / discharging stop and reset actions. Alternatively, in other embodiments, the position can be determined by detecting the torque of the driver 141 (based on the detected current value) through stop movement. Alternatively, in some embodiments, a position sensor can be set to monitor the movement of the air pump module 130 into position, such as detecting reaching the first, second, or third position, to determine the status. In some embodiments, the position sensor can be contact type (such as a microswitch, pressure sensor, etc.) or non-contact type (such as a photoelectric sensor, etc.).

[0089] like Figure 16 The diagram shown illustrates the structure for position detection of the air pump module 130 in this embodiment of the present disclosure.

[0090] exist Figure 16 In this embodiment, a position sensor 170 is disposed within the receiving cavity 1100, corresponding to a predetermined position during the movement of the air pump module 130. The air pump module 130 is provided with a detection unit 13184 that cooperates with the position sensor 170. In this embodiment, the cooperation state of the position sensor 170 and the detection unit 13184 may occur when the air pump module 130 is in an initial first position. In other embodiments, the position sensor 170 and the detection unit 13184 may also be disposed corresponding to a second position and / or a third position for determining whether the position is in place.

[0091] In some embodiments, when the detected unit 13184 moves to a position detected by the position sensor 170, the position sensor 170 may output a signal indicating a change in signal value. For example, if the micro switch is not pressed when the unit is not in position, a signal with a value of "0" is generated; or if the micro switch is pressed when the unit is in position, a signal with a value of "1" is generated.

[0092] In this embodiment, the position sensor 170 is a contact sensor, such as a microswitch. The detected part 13184 is a protrusion that extends from the air pump module 130 toward the position sensor 170 and can touch and press the position sensor 170 when moved to the corresponding position. As an example, the protrusion may be formed by the lower cover protruding outward to the side. Optionally, the protrusion may be of a gradually changing size along the direction of movement (e.g., gradually increasing and then decreasing). The protrusion causes the microswitch to press, thus changing the signal output by the position sensor 170.

[0093] Combined with the previous Figure 3 The second circuit board 152 is electrically connected to the position sensor 170. The second circuit board 152 can determine whether the air pump module 130 has returned to the first position after performing an inflation / deflation operation to move based on the signal from the position sensor 170.

[0094] Based on the above embodiments, the electrical connection parts are summarized to obtain the structure of the circuit system.

[0095] like Figure 17 The diagram shows a schematic of the circuit system of the air pump device 100 in an embodiment of this disclosure.

[0096] The first circuit board 151, in conjunction with the control components, can be a button circuit board. The first circuit board 151 is electrically connected to the second circuit board 152. The second circuit board 152 is electrically connected to the power supply line 154. The second circuit board 152 is electrically connected to the air pump motor 1315, the driver 141, and the position sensor 170.

[0097] Thus, the control component 120, the first circuit board 151, the second circuit board 152, the air pump motor 1315, and the driver 141 can form a control path for the user to control the inflation / deflation and for the air pump module 130 to move into position. The second circuit board 152 can determine whether the air pump module 130 has correctly reset to the first position after the inflation / deflation action is completed, based on the signal from the position sensor 170.

[0098] Alternatively, the air pump device 100 may further include a pressure sensor 190 electrically connected to the second circuit board 152 for detecting the inflation / deflation pressure. When the inflation / deflation pressure reaches a corresponding threshold, inflation / deflation can be stopped, and then the air pump module 130 is driven to reset to the first position.

[0099] In summary, this disclosure provides an air pump device and an air pump module, comprising: a pump housing having a receiving cavity and a first air inlet and a second air inlet connected thereto; an air pump module movably disposed within the receiving cavity, including an air pump unit; the air pump unit including an air guide cavity and an air intake port and an air exhaust port connected thereto; and a guiding mechanism fixedly disposed within the receiving cavity and movably connected to the air pump module, allowing the air pump module to be guided to different positions to switch the communication relationships between the air intake port and the air exhaust port and the first air inlet and the second air inlet, respectively, thereby opening or closing airflow paths in different directions between the first air inlet and the second air inlet. The air pump device of this disclosure has advantages such as high modularity, ease of assembly, simple air path switching, good sealing performance, and integrated charging and discharging connection.

[0100] The disclosed air pump device, on the one hand, breaks through the traditional structure that relies on valves to switch air paths, but instead treats the air pump module as a movable unit, using drive transmission to change its position and guide the airflow path for charging / discharging. It features high integration, eliminating complex components such as multi-channel connectors, simplifying the internal structure, supporting complete replacement, and significantly reducing maintenance difficulty. At the same time, due to the shortened flow path and low resistance, it increases the effective airflow per unit time.

[0101] On the other hand, a combination of planar sealing and sliding sealing can be used to improve sealing reliability.

[0102] On the other hand, the power cord can be hidden in the cover, making it neat and beautiful, suitable for use in various scenarios such as home, car, and outdoors.

[0103] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
