Description
Technical Field
[0001] This application relates to the field of air pump technology, and more particularly to an integrated pump. Background Technology
[0002] As a core device for transporting gas, air pumps are widely used in various technical fields such as medical and health care, home appliances, pneumatic tools, and automation equipment. Their working stability, ease of assembly, airflow adjustment flexibility, and noise reduction performance directly affect the user experience of end products.
[0003] An integrated pump can be understood as a pump and valve integrated into one, which integrates the pump body and solenoid valve. Currently, the pressure holding function of integrated pumps mainly relies on the pump body. This method not only makes the pump body structure cumbersome, but also makes the integrated pump structure occupy a large space and difficult to miniaturize. At the same time, its pressure holding effect is also poor. Utility Model Content
[0004] The purpose of this application is to provide an integrated pump that solves at least one of the above-mentioned technical problems.
[0005] To solve the above-mentioned technical problems, this application provides an integrated pump, including a motor, a lower shell assembly, an air pump assembly, a middle shell assembly locking and fixing component, and an upper shell assembly; The lower shell assembly has a first receiving cavity suitable for accommodating the air pump assembly. The motor is connected to the lower shell assembly and is suitable for driving the air pump assembly to operate. The middle shell assembly and the side wall of the lower shell assembly have communicating slots. There are at least two slots arranged opposite to each other. The slots are provided with the locking member, which is used to fix the lower shell assembly and the middle shell assembly. The upper shell assembly includes an upper shell having a second accommodating cavity, a fixing plate, and a check valve module disposed in the second accommodating cavity. The check valve module is disposed on the fixing plate and one end is connected to the middle shell assembly. The fixing plate is fixedly disposed inside the upper shell. A locking block is provided on the outer wall of the middle shell assembly. A locking groove adapted to the locking block is provided on the upper shell. The upper shell is detachably disposed on the middle shell assembly. In the above implementation process, this solution fundamentally solves the core pain points of existing integrated pumps—namely, their cumbersome structure, large space occupation, poor pressure holding effect, and inconvenient assembly—by constructing an integrated structure of "motor-lower shell assembly-air pump assembly-middle shell assembly-upper shell assembly." The first accommodating cavity of the lower shell assembly provides precise installation space for the air pump assembly, ensuring its operational stability. At least two locking slots and matching locking components positioned opposite each other on the sidewalls of the middle shell assembly and the lower shell assembly enable rapid positioning and secure fixing of both components, ensuring uniform stress distribution in the structural connection. The design ensures stability and prevents loosening due to vibration during operation, while also simplifying the assembly process. Fixing can be completed without complex tools, significantly improving production efficiency. The upper shell assembly achieves a detachable connection through the matching of clips and slots. This facilitates later maintenance and replacement of the check valve module, reducing maintenance costs. Furthermore, the check valve module is integrated into the second accommodating cavity of the upper shell assembly, with one end directly connected to the middle shell assembly, optimizing the airflow transmission path, effectively preventing gas backflow, and significantly improving pressure holding performance. This solves the problem of poor pressure holding performance caused by existing integrated pumps relying on the pump body itself. The highly integrated overall structure eliminates redundant components, significantly reducing the equipment size and contributing to the miniaturization of the integrated pump design.
[0006] Preferably, the middle shell assembly includes a top shell, a middle shell, and a valve plate disposed between the top shell and the middle shell; the top shell is provided with a partition boss on the side near the valve plate, the partition boss separates the top shell to form a first cavity and a second cavity surrounding the first cavity, and an airflow channel communicating between the first cavity and the second cavity is formed on the partition boss; A first air outlet and a second air outlet are formed in the first cavity, and the two ends of the airflow channel are respectively the second air outlet located in the first cavity and the third air outlet located in the second cavity; the first air outlet is connected to the outside; It also includes an adjustment assembly, which includes a movable member, an adjustment member, and an elastic member disposed between the movable member and the adjustment member. The movable member is blocked at the third vent hole, and the adjustment member is adjustablely disposed on the top shell to move away from or closer to the movable member. In the above implementation process, this solution establishes an airflow channel between the first and second cavities, enabling them to connect under specific conditions, thereby allowing for adjustment of the pressure-holding capacity. Specifically, the structural design of "movable part blocking the third air outlet + adjusting part adjusting distance + elastic part buffering" in this solution achieves precise and continuous adjustment of airflow parameters. The blocking state of the movable part on the third air outlet directly determines the airflow conduction from the second cavity to the first cavity. The adjusting part, by adjusting its position on the top shell (such as by thread adjustment), can gradually change the distance between itself and the movable part, and then change the blocking force of the movable part through the compression / reset of the elastic part. When the adjusting part is close to the movable part, the compression of the elastic part increases, and the blocking force of the movable part on the third air outlet is enhanced, requiring greater air pressure to push out the movable part and connect the first and second cavities. Conversely, when the adjusting part is far away from the movable part, the compression of the elastic part decreases, and a smaller air pressure is required to push out the movable part. This purely mechanical adjustment structure does not require complex electronic control modules, which not only reduces manufacturing costs but also reduces the risk of circuit failure.
[0007] Preferably, at least two first air outlets are provided, and a first plug-in seat is provided on the side of the top shell facing away from the valve plate, and each first plug-in seat communicates with one of the first air outlets; One end of the check valve module is adapted to be inserted into the first socket; In the aforementioned implementation process, this solution significantly improves the versatility, ease of assembly, and sealing reliability of the integrated pump through the design of multiple first air outlets and first connectors. The inclusion of at least two first air outlets enables the integrated pump to simultaneously output multiple airflows, meeting the needs of scenarios requiring multi-station air supply, such as simultaneously supplying air to different air paths of multiple small pneumatic components or medical devices, greatly expanding the product's application scenarios. The first connector on the side of the top shell facing away from the valve plate corresponds one-to-one with each first air outlet, providing a precise positioning and installation structure for the check valve module. One end of the check valve module can be directly inserted into the connector, simplifying and maximizing assembly efficiency without complex connection procedures. This not only improves production assembly efficiency but also reduces the risk of sealing failure due to assembly errors. The cooperation between the connector and the check valve module forms a tight connection structure, effectively preventing airflow leakage at the connection point and further enhancing the pressure-holding effect of the integrated pump. Furthermore, the independent design of the multiple first air outlets ensures that each airflow path does not interfere with the others, guaranteeing stable pressure and flow rate for each output airflow and improving the product's reliability. The modular design of this structure also facilitates later maintenance. When a certain gas circuit fails, the corresponding check valve module can be repaired separately.
[0008] Preferably, the check valve module includes a coil frame, a coil body, and an air nozzle. The coil body is disposed on the coil frame, and the air nozzle is disposed at one end of the coil frame and adapted to extend into the first plug-in socket. An air outlet pipe and a pressure relief seat communicating with the air nozzle are provided at the end of the coil frame away from the air nozzle. A first through hole for the air outlet pipe to extend out is formed on the upper housing. Preferably, a first groove is provided on the pressure relief seat, and sound-absorbing cotton is provided in the first groove; In the above process, the sound-absorbing cotton has excellent sound absorption and noise reduction performance, which can effectively absorb the turbulent noise and impact noise generated by the high-speed airflow during the pressure relief process, significantly reducing the overall operating noise of the integrated pump and making the product more suitable for noise-sensitive scenarios. The groove on the pressure relief seat provides a precise installation and positioning space for the sound-absorbing cotton, which can prevent the sound-absorbing cotton from shifting, falling off or deforming under the impact of the pressure relief airflow, ensuring the durability and stability of the sound-absorbing effect, and avoiding noise reduction failure due to changes in the position of the sound-absorbing cotton.
[0009] Preferably, a sealing ring is provided on the outer peripheral wall of the air nozzle; In the above implementation process, the sealing ring is made of elastic material, which can fill the tiny gap between the air nozzle and the first connector to form a tight sealing structure, effectively preventing gas leakage at the connection and improving the pressure holding effect of the integrated pump. The elasticity of the sealing ring gives it a certain deformation capacity, which can adapt to the small dimensional deviations or installation angle deviations that occur during assembly, reducing the requirements for assembly precision, improving the assembly qualification rate, reducing product scrap due to assembly errors, and lowering production costs. At the same time, the elastic sealing ring can also reduce the hard contact friction between the air nozzle and the first connector, playing a buffering role during assembly and disassembly, reducing the wear of components, extending the service life of the air nozzle and connector, and improving the overall durability of the product.
[0010] Preferably, the movable member includes a curved part and a plunger part, the plunger part is adapted to extend into the airflow channel, and the curved part is adapted to fit against the edge of the third air outlet to block the third air outlet; a first mounting hole is provided on the side wall of the top shell, an internal thread is provided in the first mounting hole, the outer wall of the adjusting member is provided with an external thread that matches the first mounting hole, and the adjusting member is adjustablely disposed in the first mounting hole; In the above implementation process, the plunger part is designed to extend directly into the airflow channel to form a sliding fit structure of "plunger-channel": on the one hand, the plunger part fits against the inner wall of the airflow channel, which can restrict the movable part to move only along the axial direction of the airflow channel, and avoid the movable part from being laterally offset due to airflow impact or vibration during the adjustment process; furthermore, on the other hand, the plunger part can also play a "flow limiting and guiding" role for the airflow, preventing the airflow from directly impacting the non-blocking area of the movable part when passing through the airflow channel, reducing the interference of airflow turbulence on the adjustment accuracy, and making the airflow pressure change more stable.
[0011] Preferably, the air pump assembly includes a cup module, a cup holder, and an eccentric wheel. The cup module is mounted on the cup holder, the eccentric wheel is rotatably connected to the cup holder, and the motor is connected to the eccentric wheel to drive the eccentric wheel to rotate.
[0012] In the above process, the motor drives the eccentric wheel to rotate, the eccentric wheel causes the leather cup holder to move, which in turn drives the leather cup module to move. The movement of the leather cup module further promotes the change of airflow to achieve air intake and exhaust.
[0013] Preferably, the lower housing assembly is provided with a first air guide shaft and a second air guide shaft along the axial direction of the motor drive shaft toward the motor side. A first air guide hole communicating with the accommodating cavity is formed on the first air guide shaft, and a second air guide hole communicating with the accommodating cavity is formed on the second air guide shaft. The diameter of the first air guide hole is larger than that of the second air guide hole. In the above implementation process, the air guiding structure of traditional air pumps is mostly a single air guiding hole, and the position is arbitrary. When the single air guiding hole is blocked, the path is completely closed. In this solution, an additional air guiding hole is added on the basis of the single air guiding hole, which can be understood as a main air guiding hole and a secondary air guiding hole. The diameter of the secondary air guiding hole is smaller than that of the main air guiding hole. Under normal conditions, the airflow mainly passes through the main air guiding hole (because the diameter of the secondary air guiding hole is smaller, the resistance is greater, so the airflow relies more on the main air guiding hole). The dual-hole design of this solution can reduce the problem of single hole blockage and achieve a longer effective service life.
[0014] Preferably, a first air inlet is formed on the partition boss, and the first air inlet communicates with the second cavity; a second through hole corresponding to the first air inlet is provided on the valve plate, and a first diaphragm is provided on the second through hole, the first diaphragm being adapted to abut against the first air inlet; The middle shell is provided with a third through hole communicating with the second through hole; the middle shell is also provided with a plurality of fourth through holes, the valve plate is provided with a fifth through hole corresponding to the fourth through hole, and a second diaphragm is provided on the fifth through hole, the second diaphragm being adapted to abut against the fourth through hole; The fifth through hole is connected to the first cavity; In the above process, when the airflow in the second cavity enters the second through hole through the first air inlet, it will push out the first diaphragm, thereby connecting the first air inlet and the second through hole. If it is in the opposite direction, since the first diaphragm abuts against the first air inlet, the airflow can only move unidirectionally from the first air inlet to the second through hole. The airflow enters the first cavity through the fourth through hole on the middle shell and then through the fifth through hole on the valve plate. After that, it is discharged through the first air outlet. When it enters the fifth through hole from the fourth through hole, it will cause the second diaphragm to open so that the fourth through hole and the fifth through hole can be connected. Conversely, since the second diaphragm abuts against the fourth through hole, if the airflow enters the fourth through hole from the fifth through hole, the second diaphragm cannot open, thereby realizing unidirectional delivery.
[0015] Compared with existing technologies, the beneficial effects of this application are as follows: This solution, by constructing an integrated structure of "motor-lower shell assembly-air pump assembly-middle shell assembly-upper shell assembly," fundamentally solves the core pain points of existing integrated pumps, such as cumbersome structure, large space occupation, poor pressure holding effect, and inconvenient assembly; the first accommodating cavity of the lower shell assembly provides precise installation space for the air pump assembly, ensuring the stability of the air pump assembly during operation; at least two locking slots and matching locking parts arranged opposite to the side walls of the middle shell assembly and the lower shell assembly realize rapid positioning and firm fixation of the two, ensuring not only the structural connection The uniform force distribution prevents loosening due to vibration during operation and simplifies the assembly process, allowing for fixation without complex tools and significantly improving production efficiency. The upper shell assembly achieves detachable connection through the matching of blocks and slots, facilitating future maintenance and replacement of the check valve module and reducing maintenance costs. Furthermore, the check valve module is integrated into the second accommodating cavity of the upper shell assembly, with one end directly connected to the middle shell assembly, optimizing the airflow transmission path, effectively preventing gas backflow, and significantly improving pressure holding performance. This solves the problem of poor pressure holding performance caused by existing integrated pumps relying on the pump body itself. The highly integrated overall structure eliminates redundant components, significantly reducing the equipment size and contributing to the miniaturization of the integrated pump design.

[0021] To further understand the utility model content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings: Example
[0022] As a core device for transporting gas, air pumps are widely used in various technical fields such as medical and health care, home appliances, pneumatic tools, and automation equipment. Their working stability, ease of assembly, airflow adjustment flexibility, and noise reduction performance directly affect the user experience of end products.
[0023] An integrated pump can be understood as a pump and valve integrated into one unit, combining the pump body and solenoid valve. Currently, the pressure-holding function of integrated pumps mainly relies on the pump body. This method not only results in a cumbersome pump body structure and a large space occupation, making miniaturization difficult, but also leads to poor pressure-holding performance. To solve the above technical problems, this embodiment provides the following technical solution: For details, please see Figure 1-7 This embodiment provides an integrated pump, including a motor 10, a lower shell assembly 20, an air pump assembly 30, a middle shell assembly 70, a locking and fixing component 40, and an upper shell assembly 50; Specifically, the lower shell assembly 20 forms a first receiving cavity 21 suitable for accommodating the air pump assembly 30, the motor 10 is connected to the lower shell assembly 20 and is suitable for driving the air pump assembly 30 to operate; the middle shell assembly 70 and the side wall of the lower shell assembly form a communicating locking groove 41, at least two locking grooves 41 are provided and are arranged opposite to each other, and a locking member is provided on the locking groove 41, the locking member is used to fix the lower shell assembly 20 and the middle shell assembly 70; Furthermore, in one embodiment, the locking member can be C-shaped, with both ends of the C-shape able to engage with the locking grooves 41 on the side walls of the lower shell assembly 20 and the middle shell assembly 70, so as to fix the lower shell assembly 20 and the middle shell assembly 70.
[0024] For further details, please see Figure 1-2There are four locking components, which fix the lower shell assembly 20 and the middle shell assembly 70 in four positions respectively.
[0025] Specifically, the upper shell assembly 50 includes an upper shell 51 with a second accommodating cavity, a fixing plate 52, and a check valve module 53 disposed in the second accommodating cavity. The check valve module 53 is disposed on the fixing plate 52 and one end is connected to the middle shell assembly 70. The fixing plate 52 is fixedly disposed in the upper shell 51. A locking block 711 is provided on the outer wall of the middle shell assembly 70. A locking groove 511 adapted to the locking block 711 is provided on the upper shell 51. The upper shell 51 is detachably disposed on the middle shell assembly 70. In the above solution, this solution fundamentally solves the core pain points of existing integrated pumps—such as cumbersome structure, large space occupation, poor pressure holding effect, and inconvenient assembly—by constructing an integrated structure of "motor 10 - lower shell assembly 20 - air pump assembly 30 - middle shell assembly 70 - upper shell assembly 50." The first accommodating cavity 21 of the lower shell assembly 20 provides precise installation space for the air pump assembly 30, ensuring the stability of the air pump assembly 30 during operation. At least two locking slots 41 and matching locking parts are arranged opposite to the side walls of the middle shell assembly 70 and the lower shell assembly 20, realizing rapid positioning and firm fixation of both, which not only ensures the structural connection... The uniform force distribution prevents loosening due to vibration during operation and simplifies the assembly process, allowing for fixation without complex tools and significantly improving production efficiency. The upper shell assembly 50 achieves a detachable connection through the matching of the locking block 711 and the locking slot 511. This facilitates the maintenance and replacement of the check valve module 53 later, reducing maintenance costs. Furthermore, the check valve module 53 is integrated into the second accommodating cavity of the upper shell assembly 50, with one end directly connected to the middle shell assembly 70, optimizing the airflow transmission path, effectively preventing gas backflow, and significantly improving pressure holding performance. This solves the problem of poor performance caused by existing integrated pumps relying on the pump body for pressure holding. The highly integrated overall structure eliminates redundant components, significantly reducing the size of the equipment and contributing to the miniaturization of the integrated pump design.
[0026] For details, please see Figure 4-5 The middle shell assembly 70 includes a top shell 71, a middle shell 72, and a valve plate 73 disposed between the top shell 71 and the middle shell 72; a partition boss 712 is provided on the side of the top shell 71 near the valve plate 73, the partition boss 712 partitions the top shell 71 to form a first cavity 713 and a second cavity 714 surrounding the first cavity 713, and an airflow channel communicating between the first cavity 713 and the second cavity 714 is formed on the partition boss 712; Specifically, a first vent 715 and a second vent 716 are formed in the first cavity 713, and the two ends of the airflow channel are the second vent 716 located in the first cavity 713 and the third vent 717 located in the second cavity 714, respectively; the first vent 715 is connected to the outside. For further details, please see Figure 2 and Figure 7 It also includes an adjustment component 60, which includes a movable member 61, an adjustment member 62, and an elastic member 63 disposed between the movable member and the adjustment member 62. The movable member is blocked at the third vent 717, and the adjustment member 62 is adjustablely disposed on the top shell 71 to move away from or closer to the movable member. In the above scheme, an airflow channel is provided between the first cavity 713 and the second cavity 714, allowing them to be connected under specific conditions, thereby enabling adjustment of the pressure-holding capacity. Specifically, the structural design of "movable part blocking the third vent 717 + adjusting part 62 adjusting the distance + elastic part 63 buffering" in this scheme achieves precise and continuous adjustment of airflow parameters. The blocking state of the movable part on the third vent 717 directly determines the airflow conduction from the second cavity 714 to the first cavity 713. The adjusting part 62 is adjusted in position on the top shell 71 (e.g., by thread adjustment). The distance between the adjusting member and the movable member can be gradually changed, thereby changing the sealing force of the movable member through the compression / reset of the elastic member 63. When the adjusting member 62 is close to the movable member, the compression of the elastic member 63 increases, and the sealing force of the movable member on the third air outlet 717 is enhanced. A larger air pressure is required to push out the movable member and connect the first cavity 713 and the second cavity 714. Conversely, when the adjusting member 62 is far away from the movable member, the compression of the elastic member 63 decreases. At this time, a smaller air pressure is required to push out the movable member. This purely mechanical adjusting structure does not require a complex electronic control module, which not only reduces manufacturing costs but also reduces the risk of circuit failure.
[0027] For details, please see Figure 2 and Figure 4 At least two first vent holes 715 are provided. A first plug-in seat 54 is provided on the side of the top shell 71 facing away from the valve plate 73. Each first plug-in seat 54 is connected to a first vent hole 715. Furthermore, one end of the check valve module 53 is adapted to be inserted into the first socket 54; In the above solution, the design of multiple first air outlets 715 and first connectors 54 significantly improves the versatility, ease of assembly, and sealing reliability of the integrated pump. The presence of at least two first air outlets 715 enables the integrated pump to output multiple airflows simultaneously, meeting the needs of scenarios requiring multi-station air supply, such as simultaneously supplying air to different air paths of multiple small pneumatic components or medical devices, greatly expanding the product's application scenarios. The first connector 54 on the side of the top shell 71 facing away from the valve plate 73 is connected to each first air outlet 715, providing a precise positioning and installation structure for the check valve module 53. One end of the check valve module 53 can be directly inserted into the connector, making the assembly process simple and efficient, eliminating the need for complex connection procedures. This not only improves production assembly efficiency but also reduces the risk of sealing failure due to assembly errors. The cooperation between the connector and the check valve module 53 forms a tight connection structure, effectively preventing airflow leakage at the connection point and further enhancing the pressure-holding effect of the integrated pump. Furthermore, the independent design of the multiple first air outlets 715 ensures that the airflows do not interfere with each other, guaranteeing stable pressure and flow rate for each output airflow and improving product reliability. The modular design of this structure also facilitates later maintenance; if a fault occurs in a particular air path, the corresponding check valve module 53 can be repaired individually.
[0028] For details, please see Figure 3 The check valve module 53 includes a coil frame 531, a coil body 533, and an air nozzle 532. The coil body 533 is disposed on the coil frame 531, and the air nozzle 532 is disposed at one end of the coil frame 531 and is adapted to extend into the first plug-in seat 54. An air outlet pipe 534 communicating with the air nozzle 532 and a pressure relief seat 535 are provided at the end of the coil frame 531 away from the air nozzle 532. A first through hole 512 for the air outlet pipe 534 to extend is formed on the upper housing 51.
[0029] Specifically, a first groove is provided on the pressure relief seat 535, and sound-absorbing cotton 536 is provided in the first groove; In the above solution, the sound-absorbing cotton 536 has excellent sound absorption and noise reduction performance, which can effectively absorb the turbulent noise and impact noise generated by the high-speed airflow during the pressure relief process, significantly reducing the overall operating noise of the integrated pump and making the product more suitable for noise-sensitive scenarios. The groove on the pressure relief seat 535 provides a precise installation and positioning space for the sound-absorbing cotton 536, which can prevent the sound-absorbing cotton 536 from shifting, falling off or deforming under the impact of the pressure relief airflow, ensuring the durability and stability of the sound-absorbing effect, and avoiding noise reduction failure due to changes in the position of the sound-absorbing cotton 536.
[0030] Specifically, a sealing ring 537 is provided on the outer peripheral wall of the air nozzle 532; In the above solution, the sealing ring 537 is made of elastic material, which can fill the tiny gap between the air nozzle 532 and the first connector 54 to form a tight sealing structure, effectively preventing gas leakage at the connection and improving the pressure holding effect of the integrated pump. The elasticity of the sealing ring 537 gives it a certain deformation capacity, which can adapt to the small dimensional deviations or installation angle deviations generated during assembly, reducing the requirements for assembly accuracy, improving the assembly qualification rate, reducing product scrap due to assembly errors, and lowering production costs. At the same time, the elastic sealing ring 537 can also reduce the hard contact friction between the air nozzle 532 and the first connector 54, playing a buffering role during assembly and disassembly, reducing the wear of components, extending the service life of the air nozzle 532 and the connector, and improving the overall durability of the product.
[0031] For details, please see Figure 7 The movable part includes a curved part 612 and a plunger part 611. The plunger part 611 is adapted to extend into the airflow channel, and the curved part 612 is adapted to fit against the edge of the third air outlet 717 to block the third air outlet 717. A first mounting hole 719 is provided on the side wall of the top shell 71. An internal thread is provided in the first mounting hole 719. An external thread that matches the first mounting hole 719 is provided on the outer wall of the adjusting member 62. The adjusting member 62 is adjustable and disposed in the first mounting hole 719. In the above scheme, the plunger part is designed to extend directly into the airflow channel, forming a sliding fit structure of "plunger-channel": on the one hand, the plunger part fits against the inner wall of the airflow channel, which can restrict the movable part to move only along the axial direction of the airflow channel, and avoid the movable part from being laterally offset due to airflow impact or vibration during the adjustment process; furthermore, on the other hand, the plunger part can also play a "flow limiting and guiding" role for the airflow, preventing the airflow from directly impacting the non-blocking area of the movable part when passing through the airflow channel, reducing the interference of airflow turbulence on the adjustment accuracy, and making the airflow pressure change more stable.
[0032] For details, please see Figure 6 The air pump assembly 30 includes a cup module 31, a cup holder 32, and an eccentric wheel 33. The cup module 31 is mounted on the cup holder 32, and the eccentric wheel 33 is rotatably connected to the cup holder 32. The motor 10 is connected to the eccentric wheel 33 to drive the eccentric wheel 33 to rotate.
[0033] In the above scheme, the motor 10 drives the eccentric wheel 33 to rotate, the eccentric wheel 33 causes the leather cup holder 32 to move, which in turn drives the leather cup module 31 to move. The movement of the leather cup module 31 further promotes the change of airflow to achieve air intake and exhaust.
[0034] Specifically, the lower housing assembly 20 is provided with a first air guide shaft 22 and a second air guide shaft 23 along the axial direction of the drive shaft of the motor 10 towards the motor 10. A first air guide hole 221 communicating with the accommodating cavity is formed on the first air guide shaft 22, and a second air guide hole 231 communicating with the accommodating cavity is formed on the second air guide shaft 23. The diameter of the first air guide hole 221 is larger than that of the second air guide hole 231. In the above solutions, the air guiding structure of traditional air pumps is mostly a single air guiding hole, and its position is arbitrary. When this single air guiding hole is blocked, the path is completely closed. In this solution, an additional air guiding hole is added to the single air guiding hole, which can be understood as a main air guiding hole and a secondary air guiding hole. The diameter of the secondary air guiding hole is smaller than that of the main air guiding hole. Under normal conditions, the airflow mainly passes through the main air guiding hole (because the diameter of the secondary air guiding hole is smaller, the resistance is greater, so the airflow relies more on the main air guiding hole). The dual-hole design of this solution can reduce the problem of single-hole blockage and achieve a longer effective service life.
[0035] Specifically, a first air inlet 718 is formed on the partition boss 712, and the first air inlet 718 communicates with the second cavity 714; a second through hole 731 corresponding to the first air inlet 718 is provided on the valve plate 73, and a first diaphragm 732 is provided on the second through hole 731, the first diaphragm being adapted to abut against the first air inlet 718. Furthermore, the middle shell 72 is provided with a third through hole 721 communicating with the second through hole 731; the middle shell 72 is also provided with a plurality of fourth through holes 722, the valve plate 73 is provided with a fifth through hole 733 corresponding to the fourth through hole 722, and a second diaphragm 734 is provided on the fifth through hole 733, the second diaphragm 734 being adapted to abut against the fourth through hole 722; Specifically, the fifth through hole 733 is connected to the first cavity 713; In the above scheme, when the airflow in the second cavity 714 enters the second through hole 731 through the first air inlet 718, it will push out the first diaphragm 732, thereby connecting the first air inlet 718 and the second through hole 731. However, if it is in the opposite direction, since the first diaphragm 732 abuts against the first air inlet 718, the airflow can only move unidirectionally from the first air inlet 718 towards the second through hole 731. The airflow further passes through the fourth through hole 722 on the middle shell 72. The airflow enters the first cavity 713 through the fifth through hole 733 on the valve plate 73, and then exits through the first air outlet 715. When the airflow enters the fifth through hole 733 from the fourth through hole 722, it will cause the second diaphragm 734 to open so that the fourth through hole 722 and the fifth through hole 733 can communicate. Conversely, since the second diaphragm 734 abuts against the fourth through hole 722, if the airflow enters the fourth through hole 722 from the fifth through hole 733, the second diaphragm 734 cannot open, thus realizing unidirectional delivery.
[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application shall fall within the scope of the technical solution of this application.
