Description

Technical Field

[0001] The present application relates to the technical field of portable devices, and in particular to an air pump and an air pump assembly thereof. Background Art

[0002] An electric air pump is a widely used portable electronic device that can inflate objects such as car tires, motorcycle tires, bicycle tires, footballs, and basketballs at a set pressure by means of electric power.

[0003] However, the existing electric air pump has a relatively single function and cannot well meet people's increasingly diverse use needs. When other types of blowing or suction operations (such as blowing off fallen leaves, vacuuming a vacuum bag) are required, other blowing and suction devices are often needed.

[0004] Therefore, it is urgently hoped to provide an air pump that has more functions and meets different usage requirements. Summary of the invention

[0005] The air pump and air pump assembly provided by the present application can at least partially overcome the defect of the existing portable air pumps having a single function.

[0006] In the first aspect, the present application provides an air pump, comprising: an air pump body, an air filling nozzle, a first opening end and a vent, the first opening end and the air filling nozzle being located on the same end surface of the air pump body; an air flow channel connecting the first opening end and the vent; the air flow channel is formed inside the air pump body; an air flow driving device housed in the air pump body, configured to perform one or more of the following functions: compressing the gas inhaled through the vent and pumping it out from the air filling nozzle; driving gas to enter from the first opening end and leave from the vent via the air flow channel; and driving gas to enter from the vent and leave from the first opening end via the air flow channel.

[0007] In the second aspect, the present application provides an air pump assembly. The air pump assembly includes: the air pump as described above; the air nozzle of the air pump is a threaded interface; and at least one air nozzle accessory; the air nozzle accessory includes: an accessory body; the interior of the accessory body is hollow, and has a working end face and a joint end face that are separated from each other; an accessory bracket fixed inside the accessory body; at least a portion of the accessory bracket is hollowed out to allow gas to pass through the accessory body; a threaded connector fixed to the accessory bracket; the threaded connector protrudes from the accessory bracket; wherein, in response to the threaded connector being detachably threadedly connected to the air nozzle, the joint end face of the accessory body is in contact with the end face of the air pump body, and the accessory body covers the first open end of the air pump.

[0008] At least one advantage of the air pump and air pump assembly provided by the embodiments of the present application is that by adding additional air flow channels and related supporting structures, the air pump has both blowing and suction functions on the basis of the inflation function, which can more comprehensively meet people's various usage needs and reduce the number of devices that need to be carried. Moreover, the connection interfaces required for the air pump to perform different functions are arranged on the same end surface, which can facilitate the assembly and disassembly of the air pump accessories and further enhance the user experience.

[0056] The present application is described in detail below in conjunction with specific embodiments. It should be emphasized that the following description is merely illustrative and is not intended to limit the scope of the present application and its application.

[0057] It should be noted that, unless otherwise clearly specified and limited, the terms "center", "longitudinal", "lateral", "up", "down", "vertical", "horizontal", "inside", "outside", etc. used in this specification indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. Terms such as "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium.

[0058] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features; thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; "multiple" means two or more; "and / or" includes any and all combinations of one or more related listed items. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0059] 1. Explanation of terms:

[0060] "End face" refers to the surface formed by the end of an object or structure in the direction of its main axis. It is located at both ends of the object or structure, and its shape depends on the overall shape and design of the object or structure.

[0061] "Several" is an indefinite word that means one or more. It can indicate a smaller number or a larger number. It is intended to indicate the non-specificity of the number and to allow the number to be adjusted as needed in actual applications.

[0062] The term "peripheral surface" refers to the continuous outer surface of an object or structure excluding the end surfaces at both ends, which constitutes the interface between the object or structure and the surrounding environment.

[0063] "Airflow channel" refers to a specific path or spatial structure in an object or structure used to guide and control the flow of gas. It provides a physical space for gas flow and has a clear gas inlet and gas outlet.

[0064] "Surround" means that the structural element surrounds a specific structural element or region in all or most directions, forming a complete or nearly complete surrounding state, and is not used to imply a specific shape.

[0065] "Assembly" refers to the process of combining two or more independent parts or sub-assemblies according to a predetermined design and method to form a more complex functional unit or complete product.

[0066] "Inflating function" refers to the ability of the device to deliver compressed air or gas into a closed container or system in a controlled manner to reach a specific high pressure level. It is suitable for application scenarios that require precise and higher pressure.

[0067] The "blowing function" refers to the ability of the device to generate a continuous, low-pressure but high-flow airflow. Compared with the inflation function, it focuses more on the volume of the airflow rather than the pressure output, and is suitable for application scenarios such as blowing away objects or filling deformable containers.

[0068] The "suction function" refers to the ability of the device to create a negative pressure or vacuum state to inhale and collect air, gas or light substances. This can be achieved by reversing the airflow direction of the blowing function, and is suitable for recycling deformable containers and cleaning applications.

[0069] 2. About the air pump:

[0070] Figure 1 This is a schematic diagram of the structure of the air pump provided in an embodiment of the present application from a front perspective. Figure 2 This is a schematic diagram of the structure of the air pump provided in an embodiment of the present application from a back perspective. Figure 3 A cross-sectional view of an air pump provided in an embodiment of the present application.

[0071] The air pump has multifunctional characteristics. In addition to providing basic inflation functions, it can also switch between blowing and inhaling functions to meet the needs of use in different scenarios.

[0072] like Figure 1 and Figure 2 As shown, the air pump includes: an air pump body 10 and a plurality of openings opened at different positions on the surface of the air pump body 10 .

[0073] The air pump body 10 is the main structure of the entire air pump, which can be set to any type of size and shape according to the actual needs, and is composed of one or more different structural parts, which are not specifically limited here.

[0074] For example, the air pump body 10 can be roughly divided into a main body portion 11 and a grip portion 12. The main body portion 11 is an elongated three-dimensional structure extending along an axis to a certain length, while the grip portion 12 is a strip-shaped structure extending from the main body portion 11 along another axis to a certain length.

[0075] In the present application, since the main body 11 is the main part of the entire air pump body 10, the axial direction of the main body 11 is called the "main axis", and the two end faces of the main body 11 that are opposite to each other on the main axis are respectively called the first end face S11 and the second end face S12.

[0076] For details, please continue to refer to Figure 1 and Figure 2 There is a certain angle between the extending direction of the grip portion 12 and the main axis, so that a corresponding inclination angle is formed between the grip portion 12 and the main body 11, so that the user can hold the air pump more comfortably when using it. For example, the extending direction of the grip portion 12 can form an angle of approximately 90° with the main axis of the main body 11.

[0077] Of course, other suitable preset angles may be selected according to actual needs, or an angle adjustment mechanism may be provided to enable the tilt angle between the grip portion 12 and the main body portion 11 to be adjustable.

[0078] The above opening is a gap area that allows gas to pass through so that gas enters or leaves the air pump body. The multiple gaps can be divided into: a vent 20, an air filling nozzle 21 and a first opening end 31 according to their arrangement positions and functions.

[0079] The vent 20 and the inflation nozzle 21 cooperate with each other to realize the inflation function. A continuous air duct is formed between the two, so that external air can enter the interior of the air pump body 10, and after being compressed, it leaves the air pump body at a set pressure.

[0080] The vent 20 also cooperates with the first open end 31 to realize the blowing / inhaling function. When the inhaling function is used, the gas inside the air pump body is quickly discharged through the vent 20, thereby forming a certain negative pressure at the first open end 31, so that the external air is drawn into the air pump body. When the blowing function is used, the external air is drawn into the air pump body through the vent 20, and blown out at a relatively fast speed at the first open end 31.

[0081] In addition, the ventilation holes 20 opened on the air pump body can cooperate with each other to form gas exchange between the air inside the air pump body and the external air. Through gas exchange, the heat generated by the devices and functional modules inside the air pump body can be taken away more quickly, thereby achieving a good heat dissipation effect.

[0082] Specifically, the vent 20 may include an air inlet 22 and a second open end 32. The air inlet 22 cooperates with the inflation nozzle 21 to realize the inflation function, and the second open end 32 cooperates with the first open end 31 to realize the blowing / inhaling function.

[0083] A heat dissipation hole is formed between the air inlet 22 and the second open end 32 , and a corresponding heat dissipation function is exerted by exchanging gas between the inside and outside of the air pump body.

[0084] The above-mentioned multiple different openings can be selectively arranged at any suitable position of the air pump body 10 according to actual needs, and different effects can be obtained accordingly.

[0085] For example, Figure 1 and Figure 2 As shown, the air inlet 22 can be arranged at the bottom of the gripping portion 12 to avoid unnecessary obstruction when the air pump is working. Figure 1 and Figure 2 The second opening end 32 can be arranged on the outer peripheral surface of the main body part 11, and is arranged circumferentially around the main axis, so as to facilitate the movement of gas between the first opening end 31 and the second opening end 32, reduce the structural design difficulty of the air flow channel connecting the two, and help provide a better blowing / inhaling effect.

[0086] Preferably, the first opening end 31 and the inflation nozzle 21 are disposed on the same end surface of the air pump body. Figure 1 and Figure 2 As shown, the first opening end 31 and the inflation nozzle 21 are both arranged on the first end surface S11 of the air pump body, wherein the inflation nozzle 21 is located at the center of the first end surface S11, and the first opening end 31 is arranged around the inflation nozzle 21.

[0087] By arranging the first opening end 31 and the inflation nozzle 21 on the same end surface, the openings required for the inflation function, the suction function and the blowing function are arranged on the same surface, thereby facilitating the user's operation and providing a compact structural design.

[0088] Figure 3 FIG. 1 shows an exemplary air flow channel in the air pump body 10 for connecting the first opening end 31 and the second opening end 32. Of course, those skilled in the art can also adjust the physical shape, size and extension path of the air flow channel C according to actual needs, without being limited to Figure 3 As shown, it is sufficient to enable communication between the first open end 31 and the second open end 32 .

[0089] The "airflow driving device" is a general term for the related structures and components that provide driving force for the gas to move or flow in the air pump body. It is completely housed inside the air pump body 10 and can perform the inflation function, the blowing function or the suction function according to the external operation instructions applied by the user.

[0090] For example, when performing the inflation function, the airflow driving device is used to compress the gas inhaled through the air inlet 22, and pump the compressed gas with the expected pressure out from the inflation nozzle 21. When performing the inhalation function, the airflow driving device is used to provide a positive driving force to drive the external gas to be inhaled by the first opening end 31 and leave from the second opening end 32 through the airflow channel. When performing the blowing function, the airflow driving device is used to provide a reverse driving force to drive the gas to enter from the second opening end and blow out from the first opening end through the airflow channel.

[0091] Therefore, by further adding a new airflow driving device, a first opening end, a second opening end and an airflow channel connecting the first opening end and the second opening end on the basis of the traditional air pump, the air pump can have inflation function, blowing function and suction function, so as to better meet the user's needs for multi-purpose portable devices.

[0092] 2. About airflow drive device:

[0093] Figure 4 A cross-sectional view of an air pump provided in an embodiment of the present application. Figure 4 As shown, the airflow driving device may include: a first gas driving unit 41 , a second gas driving unit 42 and an energy storage unit 43 .

[0094] The first gas drive unit 41 is a power component designed to realize the blowing function and the suction function. It can be implemented by any suitable type of fan device (for example, a high-speed brushless motor with built-in fan blades and a brushed high-speed motor with fan blades installed at the motor output shaft end) according to the actual needs, as long as it can provide a driving force that meets the design requirements, the driving gas enters from the first opening end 31 and leaves from the second opening end 32 through the air flow channel, and the driving gas enters from the second opening end 32 and leaves from the first opening end 31 through the air flow channel.

[0095] The second gas drive unit 42 is a power component designed to realize the inflation function. It can also select any suitable type or model of air pump mechanism (for example, a vane air pump mechanism or a piston air pump mechanism) according to the actual needs, as long as it can provide the compression capacity that meets the design requirements, compress the gas sucked in by the air inlet 22 and pump it out from the inflation nozzle 21 through the corresponding connecting pipe at the expected air pressure.

[0096] The energy storage unit 43 is a device that can store electrical energy by chemical energy conversion. For example, a battery pack composed of a plurality of battery cells connected in series and / or in parallel is used as a power source for the air pump to supply power to the first gas drive unit 41 and the second gas drive unit 42.

[0097] Specifically, in order to reasonably utilize the space, the air pump body is provided as compact as possible. Figure 4 , the first gas driving unit 41 and the plurality of battery cells 431 may be arranged in the main body portion 11 , while the second gas driving unit 42 may be arranged in the grip portion 12 .

[0098] Thus, the second gas driving unit 42 can compress the air sucked from the air inlet 22 located at the end of the gripping portion 12 , and pump the compressed air out from the inflation nozzle 21 .

[0099] Alternatively, the arrangement positions of the first gas drive unit 41 and the second gas drive unit 42 may also be interchanged. For example, the first gas drive unit 41 is arranged in the grip portion, while the second gas drive unit 42 is arranged in the main body portion.

[0100] For further information, please refer to Figure 4 It is also possible to arrange the first gas driving unit 41 along the main axis and arrange the plurality of battery cells 431 around a portion of the edge of the first gas driving unit 41 to provide a more compact main body 11.

[0101] Thus, the first gas driving unit 41 can provide a positive driving force or a reverse driving force to drive air to flow in the air flow channel inside the main body portion 11 , thereby forming a negative pressure suction or blowing gas at the first opening end 31 .

[0102] Alternatively, one of the first gas drive unit and the second gas drive unit may be omitted. For example, when the gas drive unit has strong performance and can support a wide range of gas pressure regulation, the airflow drive device may also include only one gas drive unit and a corresponding energy storage unit.

[0103] Thus, the gas drive unit can, based on externally applied operating instructions, drive gas to enter from the first opening end 31 and leave from the second opening end 32 via the air flow channel, or drive gas to enter from the second opening end 32 and leave from the first opening end 31 via the air flow channel, or compress the air inhaled through the air intake port 22 and pump the compressed air out from the inflation nozzle 21.

[0104] 3. About the main part of the air pump:

[0105] Figure 5A schematic diagram of partial structural decomposition of the air pump provided in an embodiment of the present application. Figure 6 This is a schematic diagram of an exploded view of the air pump provided in an embodiment of the present application.

[0106] In some embodiments, Figure 5 As shown, the main body 11 includes: a main shell 111 and a main bracket 112 .

[0107] The main housing 111 is the outer surface of the main body 11, which is used to surround and protect the internal components and form a specific outer contour. It can be set to a suitable thickness, size and shape according to the actual needs, so as to provide an appropriate accommodation space inside. For example, Figure 5 The generally cylindrical shape is shown.

[0108] For details, please continue to refer to Figure 5 The main shell 111 can be formed by a shell body 1101, a cover plate 1102 and a connecting ring 1103.

[0109] One end of the shell body 1101 is open, and a receiving space for accommodating the main bracket 112 is formed inside. The main bracket 111 is assembled and fixed inside the shell body 1101. The cover plate 1102 is fixed to the bracket end of the main bracket 111. The connecting ring 1103 is located between the shell body 1101 and the cover plate 1102.

[0110] The two sides of the connecting ring 1103 that are away from each other on the main axis are respectively engaged with the open end of the shell body 1101 and the cover plate 1102, thereby enclosing and forming a complete main shell 111 that surrounds the main bracket 112.

[0111] Thus, the cover plate 1102 constitutes the first end surface S11 of the air pump body, and the closed end of the shell body 1101 opposite to the open end constitutes the second end surface S12 of the air pump body. The connecting ring 1103 is a structural member with a plurality of through holes (for example, a metal ring with mesh holes), and the second open end 32 is formed by these through holes.

[0112] The main bracket 112 is a structural frame that is received and fixed inside the main housing 111 and is used to fix and support various functional components. In this application, the space formed by the main bracket 112 and used to fix and accommodate functional components is referred to as an installation position.

[0113] For example, the main bracket 112 may form a first installation position for accommodating the first gas drive unit 41 and a second installation position for accommodating the battery cell 431. The number of the second installation positions is consistent with the number of battery cells.

[0114] In addition, at least a portion of the main bracket 112 is physically connected to the main housing 111 to ensure that the main bracket 112 remains fixed in the main housing 111. Figure 3 As shown, a portion of the main bracket 112 can be engaged with the main shell 111 through a first buckle B01, so that the main bracket 112 is fixedly connected to the main shell 111.

[0115] Furthermore, the main bracket 112 cooperates with the main housing 111 to form a required air flow channel. Figure 8 As shown, the main support 112 may be provided with ventilation holes 1123 for gas to pass through, so as to form the above-mentioned air flow channel.

[0116] Moreover, these ventilation holes 1123 make the main bracket 112 have a hollow structural design, and can also reduce the physical weight of the main bracket 112.

[0117] Specifically, Figure 7 and Figure 8 As shown, the main support 112 may include a first support end 1121a, a second support end 1121b, and a spacing structure 1122 located between the first support end and the second support end.

[0118] The first bracket end 1121a is the portion close to the first end face of the air pump body. The second bracket end 1121b is the portion close to the second end face of the air pump body. The spacing structure 1122 extending along the main axis forms the above-mentioned first installation position and second installation position, which are respectively used to accommodate the first gas drive unit 41 and the battery cell 431.

[0119] A plurality of mutually spaced battery cells 431 may be connected in series or in parallel via electrical connectors 44 to form a complete energy storage unit to provide and output a required voltage.

[0120] Based on the above-mentioned position setting method of the main bracket 112, in some embodiments, please continue to refer to Figure 7 The inflation nozzle 21 can be arranged at the center of the first bracket end 1121a. Accordingly, the cover plate 1102 is provided with a through hole adapted to the position of the inflation nozzle 21, so that the inflation tube or similar external accessories can smoothly establish a detachable sealed connection with the inflation nozzle 21 to complete the inflation of the inflatable object.

[0121] Preferably, if Figure 6As shown, a shock-absorbing pad 53 may be sandwiched between the inflation nozzle 21 and the cover plate 1102. The shock-absorbing pad 53 is made of an elastic material (for example, soft glue or other flexible materials) and is sleeved on the outer periphery of the inflation nozzle 21, thereby forming an elastic buffer interlayer between the inflation nozzle 21 and the cover plate 1102. The buffer interlayer formed by the shock-absorbing pad 53 can prevent the two from generating noise due to mutual vibration and collision during inflation.

[0122] In other embodiments, please refer to Figure 7 The first opening end 31 can also be arranged at the first bracket end 1121a, and is realized by a central hole opened at the first bracket end 1121a. Accordingly, a grid 1104 is arranged at a position area of ​​the cover plate 1102 opposite to the central hole of the first bracket end 1121a, so as to guide the gas to pass through the first opening end 31 smoothly.

[0123] Preferably, if Figure 1 As shown, the grille 1104 may be composed of a plurality of blade structures in a radial shape. These blade structures extend outward from the central inflation nozzle, and the extending direction is inclined at a certain angle, rather than being completely straight.

[0124] Therefore, when the airflow passes through the grille 1104, the inclined blade structure can guide the airflow to produce a rotational motion, so that the airflow can be more evenly distributed throughout the first opening end 31, effectively improving the uniformity of the airflow and reducing the airflow noise.

[0125] 4. About the grip part of the air pump body 12:

[0126] In some embodiments, please refer to Figure 5 The holding portion 12 may be composed of a holding inner cover 121 , a holding outer cover 122 , an end connecting ring 123 and a holding foot pad 124 .

[0127] The grip inner cover 121 is a shell component that surrounds and accommodates the second gas drive unit 42 , and provides an internal space that is compatible with the second gas drive unit 42 .

[0128] For example, Figure 5 FIG. 1 shows a structural implementation in which a portion 121 a of the grip inner cover 121 is integrally formed with the main body portion 111 , and another independent portion 121 b of the grip inner cover 121 is fixedly connected to the integrally formed portion 121 a by screws 92 .

[0129] Alternatively, the independent part 121b and the main body integrally formed part 121a may also be fixedly connected by means of snap fastening or gluing.

[0130] The grip outer cover 122 is sleeved outside the grip inner cover 121 to form the main outer surface of the grip portion 12. The terminal connection ring 123 can be a mesh structure (eg, an annular metal mesh) with a plurality of through holes to form the air inlet 22 mentioned above.

[0131] The terminal connection ring 123 can be locked and fixed on the grip inner cover 121 by any suitable type of fixing connection method such as screws. Thus, the terminal connection ring 123 can prevent the grip outer cover 122 from coming out, and its position is also fixed. The grip foot pad 124 is fixedly covered on the bottom end of the terminal connection ring 123 to form a complete grip part 12.

[0132] 5. About the main bracket:

[0133] Fig. 9 This is a schematic diagram of the exploded structure of the main support provided in the embodiment of the present application. Fig. 9 As shown, the main support 112 may be composed of a first battery cell support 112 a and a second battery cell support 112 b .

[0134] The first battery holder 112a and the second battery holder 112b have a matching structure design, and the two are fixedly connected by any suitable type of method ( Fig. 9 The figure shows, by way of example, the use of screws to fix the connection to form the main bracket 112.

[0135] The first battery cell support 112a includes: a first support end 1121a and a first spacing structure 1122a. Similarly, the second battery cell support 112b includes: a second support end 1122b and a second spacing structure 1122b.

[0136] The first spacing structure 1122a and the second spacing structure 1122b respectively provide a mounting hole H1 on the main axis and a plurality of battery cell slots H2 arranged along the circumference of the mounting hole ( Fig. 9 2 ) The mounting hole H1 and each of the battery cell slots H2 are holes spaced apart from each other.

[0137] Thus, when the first cell holder 112a and the second cell holder 112b are fixedly connected so that the two ends of the first spacing structure 1122a and the second spacing structure 1122b are engaged with each other, the mounting holes formed by the two spacing structures will cooperate to form the above-mentioned first mounting position for mounting and placing the first gas drive unit 41. The corresponding cell slots formed by the two spacing structures will cooperate to form the above-mentioned second mounting position for mounting and placing the cell 431.

[0138] Alternatively, when the battery cell and the first gas drive unit have a specific axial length, the first spacing structure 1122a and the second spacing structure 1122b may not be engaged with each other, and there may be a certain gap. It is only necessary to ensure that the battery cell and the first gas drive unit can be stably clamped and fixed between the first battery cell holder 112a and the second battery cell holder 112b.

[0139] Specifically, the first installation position and the second installation position formed in the main bracket 112 are both arranged along the axis direction of the air pump body. Therefore, the battery cell 431 assembled and fixed at the second installation position is also arranged along the same axis direction, so that the center of gravity of the entire air pump body is stable, which is convenient for holding the air pump and effectively improves the use experience of the air pump.

[0140] 6. About the lighting function of the air pump:

[0141] In some embodiments, please refer to Figure 1 The air pump may also be provided with an additional lighting device 60 on the first end surface S11 of the air pump body to provide a lighting function for the user.

[0142] Thus, when the lighting device 60 is turned on, light can be emitted to illuminate the area in front of the first end surface S11 of the air pump. This design also facilitates users to establish connections between other accessories and the air nozzle or the first opening end disposed on the first end surface S11 in a dark environment.

[0143] For details, please continue to refer to Figure 5 The lighting device 60 may include: a lamp panel 61 and a lampshade 62 .

[0144] The lamp board 61 is fixed to the first bracket end 1121a and is arranged around the first open end 31. The lampshade 62 has a size adapted to the lamp board 61 and is fixedly connected to the cover plate 1102 to cover the lamp board 61, thereby protecting the lamp board 61 and focusing light.

[0145] For example, Figure 5 A ring-shaped lamp panel 61 and a lamp cover are shown in the figure, but those skilled in the art will appreciate that a lamp panel and a lamp cover of any other suitable shape or size may be used according to actual needs.

[0146] in addition, Figure 5 The lamp panel 61 is also fixed to the bracket end of the main bracket 112 by means of screws 93, and the lampshade 62 is fixed to the cover plate 1102 by means of snap connection. However, those skilled in the art will appreciate that any other suitable type of fixed connection method may be used to achieve the fixed connection between the lamp panel, the lampshade, the cover plate and the bracket end.

[0147] Alternatively, other similar structures may be used to implement the lighting device 60, without limitation. Figure 5 For example, the cover plate 1102 and the lampshade 62 are directly formed into a complete structure, and the function of the annular lampshade is realized by arranging a corresponding transparent area on the cover plate 1102 .

[0148] 7. About the interactive components of the air pump:

[0149] In some embodiments, please refer to Figure 2 The air pump further includes: a plurality of interactive components 70 arranged on the second end surface S12 of the air pump body.

[0150] The interactive component 70 is a functional component that enables the user to interact with the air pump. It serves as a bridge for information transmission, allowing the user to input data, issue instructions, and obtain feedback information from the air pump. Fig.13 As shown, the interactive component 70 may include a display area 71 that provides visual feedback information and a control button 72 that receives user input data and instructions.

[0151] Specifically, Fig.11 As shown, the display area 71 and the control button 72 can be realized by a circuit component 80 fixed to the second bracket end 1121b.

[0152] The circuit assembly 80 can be integrated with corresponding electronic devices and functional circuits according to actual needs, and is composed of one or more components (for example, a key circuit for sensing touch operations, a display assembly for presenting visual information, and a control circuit, etc.).

[0153] In some embodiments, Fig.12 As shown, an appropriate gap R1 may be retained between the circuit assembly 80 fixed to the second bracket end 1121b and the second spacing structure 1122b so that the gas can smoothly enter the air duct R2 located in the first installation position.

[0154] By providing a variety of interactive components on the second end face of the air pump, the user can conveniently control and operate the air pump and switch between a variety of functions, thereby effectively improving the user experience.

[0155] 8. About the interactive process of the air pump:

[0156] Fig.13 It is a schematic diagram of the control button 72 provided in an embodiment of the present application. Fig.14 Schematic diagram of the display area 71 provided in the embodiment of the present application. Fig.13 and Fig.14, describing in detail the interaction process between the user and the air pump when using the air pump.

[0157] In some embodiments, Fig.13 As shown, the control buttons 72 are configured as: a start button 721 , a mode selection button 722 , a lighting function button 723 , an air pressure increase button 724 , and an air pressure decrease button 725 .

[0158] like Fig.14 As shown, the display area 71 has a first visual content 711 displaying air pressure units, a second visual content displaying air pressure values, and a third visual content displaying a plurality of inflation modes, a blowing mode, and an inhalation mode.

[0159] The air pressure units in the first visual content 711 are set to KPA, BAR and PSI. The second visual content uses two sets of display values ​​with different font sizes to respectively present the current real-time air pressure value 712a of the air pump and the set air pressure setting value 712b. The third visual content is represented by different icons: blowing mode 713a, suction mode 713b, inflation mode 713c for inflating car tires, inflation mode 713d for inflating motorcycle tires, inflation mode 713e for inflating bicycle tires, and inflation mode 713f for inflating balls.

[0160] 1) Turn off / start the air pump:

[0161] When the air pump is in the off state, the display area 71 is off and no feedback information is displayed. Only the control button 72 appears on the second end face of the air pump body. At this time, the user can start the air pump by long pressing the start button 721 to put the air pump into the on state. After the air pump is turned on, the display area 71 will show Fig.14 The interactive interface shown.

[0162] 3) Air pressure unit selection:

[0163] After the air pump is turned on, the user can switch between the three different air pressure units by short pressing the mode selection button 722. In the display area 71, the selected air pressure unit will be lit up and can be visually observed. The unselected ones are in an off state and are not displayed.

[0164] 4) Air pressure adjustment:

[0165] After the air pump is turned on, the user can also increase the air pressure setting value by short pressing the air pressure increase button 724, and reduce the air pressure setting value by short pressing the air pressure decrease button 725. The display area 71 will display the current air pressure setting value 712b in real time as the user operates.

[0166] 5) Inflation mode selection:

[0167] The above four inflation modes are pre-set in the air pump to facilitate users to quickly adjust and reduce the frequency and number of operations. The default inflation parameters are set for different mode usage scenarios.

[0168] The user can switch between the four inflation modes by short pressing the mode selection button 722. The icon corresponding to the currently selected inflation mode will be lit, and the icon of the inflation mode not selected will not be displayed.

[0169] In addition, the air pressure setting value 712b of the currently selected inflation mode will also be displayed synchronously in the second visual content, so that the user can intuitively know the air pressure conditions under different inflation modes.

[0170] 6) Free inflation mode:

[0171] After the air pump is turned on, the user can also enter the free inflation mode by short pressing the start button 721. In the free inflation mode, the air pump directly inflates and displays the current real-time air pressure value.

[0172] 7) Lighting function:

[0173] The lighting function is designed as a control method for cyclic switching between three different states: lighting-flashing-off. After the air pump is turned on, the user first short presses the lighting function button 723 to activate the lighting function of the air pump. At this time, the lighting device located on the first end face of the air pump body lights up to serve as a lighting function. Then, on this basis, short press the lighting function button 723 again to switch the air pump to the flashing function. At this time, the lighting device 60 flashes at a set frequency to serve as a call for help. Finally, short press the lighting function button 723 again in the flashing state to turn off the lighting function. At this time, the lighting device is extinguished.

[0174] 8) Blowing / inhaling function:

[0175] After the air pump is turned on, the user can switch between the blowing mode, the suction mode and the four inflation modes by short pressing the mode selection button 722. Similarly, the icon corresponding to the currently selected mode will be lit, and the icon of the unselected mode will not be displayed, so as to provide the user with feedback on the current working status of the air pump.

[0176] 9. Assembly process of the air pump:

[0177] The following Figure 6 As an example, the decomposed structure diagram of the air pump shown in the figure is combined with Figure 5 , Fig. 9 as well as Fig.12 , describe the assembly process of the air pump in detail.

[0178] Assembly process of the main bracket:

[0179] like Fig. 9 As shown, the battery cell 431 and the first gas drive unit 41 are respectively installed in the mounting holes H1 and the battery slots H2 corresponding to the first battery cell holder 112a and the second battery cell holder 112b. Then, the first battery cell holder 112a and the second battery cell holder 112b are locked and fixedly connected using screws 91.

[0180] Finally, the first negative electrode nickel sheet 441 and the first connecting nickel sheet 442 are spot welded to the end of the battery cell 431 on the side of the first battery cell holder 112a, and the second negative electrode nickel sheet 443 and the second connecting nickel sheet 444 are spot welded to the end of the battery cell 43 on the side of the second battery cell holder 112b, so that multiple battery cells 431 are connected in series to form an energy storage unit.

[0181] Thus, the assembly is obtained as Figure 7 and Figure 8 As shown, a main bracket is mounted with a battery cell and a first gas drive unit.

[0182] like Fig.12 As shown, the first circuit main board 81 is fixed to the second bracket end of the second battery bracket 112b where the second negative nickel sheet 443 and the second connecting nickel sheet 444 have been welded, using screws 94, and the second circuit main board 82 and the screen bracket 83 are locked and fixed together using screws 95. Finally, the second circuit main board 82 and the screen bracket 83, which have been locked and fixed together, are fixed in a stacked manner on the first circuit main board 81 that has been fixed to the second battery bracket 112b using screws 96, and the shock absorbing pad 53 is sleeved on the inflation nozzle 21.

[0183] Thus, the assembly is obtained as Fig.10 and Fig.11 As shown, the main bracket with shock absorbing pads and circuit components installed.

[0184] like Figure 6 As shown, after one end of the air pipe 51 is connected to the compressed air output end of the second gas drive unit 42, both are assembled into the main housing 111 at the same time. Subsequently, the other end of the air pipe 51 is connected to the inflation nozzle 21 provided on the first battery holder 112a, and the main holder 111 equipped with the shock absorbing pad and the circuit assembly is inserted into the housing body 1101 through the opening end of the housing body 1101.

[0185] At this time, a plurality of buckles arranged in the circumferential direction at the open end of the shell body 1101 are buckled with matching buckle grooves on the first battery holder 112 a , so that the main holder 112 is fixed in the shell body 1101 .

[0186] Furthermore, screws may be used to lock and fix the main bracket 112 inside the shell body 1101 to ensure a stable and reliable connection between the two.

[0187] like Figure 5 As shown, the independent part 121 b of the grip inner cover is locked and fixed to the integrally formed part 121 a of the grip inner cover 121 using screws 92 to form a complete grip inner cover 121 .

[0188] Then, after the holding outer cover 122 and the end connecting ring 123 are sequentially mounted on the holding inner cover 121, the end connecting ring 123 is locked and fixed on the holding inner cover 121 using screws, and the holding foot pad 124 is mounted and fixed on the bottom opening of the end connecting ring 123 to complete the assembly of the holding part.

[0189] Please continue reading Figure 5 , assemble the connecting ring 1103 to the open end of the shell body 11 , and cover the cover plate 1102 to the end of the main bracket 112 and fix it.

[0190] Specifically, Fig.18 As shown, the cover plate 1102 and the first battery holder 112a are buckled together by the second buckle B02, and the fixed connection between the two is achieved by the buckle connection. The second buckle B02 can be set to multiple, evenly arranged around the circumference of the cover plate and the first battery holder 112a.

[0191] Then, the lamp board 61 is installed inside the lamp slot formed by the cover plate 1102, and the lamp board 61 and the cover plate 1102 are fixed together to the bracket end of the main bracket by screw locking.

[0192] Finally, the lampshade 62 is fixed above the lamp slot of the cover plate 1102 by a detachable fixing connection method such as a snap connection, so that the cover is sleeved on the lamp board 61, and the assembly of the main body is completed.

[0193] 10. Gas flow path of the air pump:

[0194] When the air pump performs the inflation function: Fig.15 and Fig.16As shown, the external air is sucked into the inside of the gripping part 11 through the air inlet 22. After being compressed by the second gas driving unit 42 accommodated in the gripping part 11, the compressed gas is output from the top of the second gas driving unit 42, passes through the air pipe 51 bent at approximately 90 degrees, reaches the inflation nozzle 21 located at the end of the first bracket, and is pumped out from the inflation nozzle 21.

[0195] When the air pump performs the blowing function, Fig.17 and Fig.18 As shown, under the drive of the first gas driving unit 41, the external air enters the space between the main housing 111 and the main bracket 112 through the second opening end 32 formed by the connecting ring 1103. Then, it enters the internal air duct of the first installation position through the gap between the second spacing structure and the circuit assembly 80. Finally, it is blown out from the first opening end 31 formed at the end of the first bracket at an accelerated speed.

[0196] When the air pump performs the suction function, Fig.19 and Fig. 20 As shown, the first gas driving unit 41 provides a reverse driving force, so that the external air enters the internal air duct of the first installation position through the first opening end 31. Then, the air passes through the gap between the second spacing structure and the circuit assembly 80 and enters the space between the main housing 111 and the main bracket 112. Finally, the air leaves the main body 11 from the second opening end 32 formed by the connecting ring.

[0197] 11. Connection method of air pump and air nozzle accessories:

[0198] Based on the air pump provided by one or more of the above embodiments, the present application further provides a series of air nozzle accessories used in conjunction with the air pump. These air nozzle accessories are detachably connected to the air pump to meet the needs of different usage scenarios.

[0199] Fig.21 Schematic diagram of the air pump assembly provided in the embodiment of the present application. Fig.21 As shown, the inflation nozzle 21 of the inflation pump 1 uses a threaded interface. One end of the external air pipe 2a is connected to the inflation nozzle 21 by a threaded connection, and the other end of the external air pipe 2a is connected to the inflated object (for example, a tire or a ball) to complete the inflation operation.

[0200] Fig. 22 This is a schematic diagram of an air pump assembly provided in another embodiment of the present application, which shows a variety of air nozzle accessories used in conjunction with the blowing function and the inhalation function, in addition to the external air tube used in the inflation function.

[0201] like Fig. 22As shown, the air nozzle accessories include: three types of blowing nozzle accessories with different air outlet diameters and an air suction nozzle accessory 2c. Of course, those skilled in the art can also choose to set other air nozzle accessories with more quantities or specifications according to actual needs, which is not specifically limited here.

[0202] In this application, for the sake of simplicity, the blowing nozzle accessory with the largest outlet diameter is called the "first blowing nozzle accessory 2b1", the blowing nozzle accessory with a medium outlet diameter is called the "second blowing nozzle accessory 2b2", and the blowing nozzle accessory with the smallest outlet diameter is called the "third blowing nozzle accessory 2b3".

[0203] Among them, the first blowing nozzle accessory 2b1 can be used in scenarios where larger blowing objects (for example, inflatable beds and inflatable boats) are used. The second blowing nozzle accessory 2b2 can be used in scenarios where some small and medium-sized blowing objects (for example, household inflatable pillows, inflatable mattresses) are used. The third blowing nozzle accessory 2b3 is used in scenarios where small blowing objects (for example, swimming rings, small inflatable dolls) or blowing and cleaning are used. The suction nozzle accessory 2c can be used in scenarios where the blowing object is quickly recovered or the vacuum bag is vacuumed. It can quickly extract the residual air inside the suction object to reduce its occupied volume.

[0204] Traditionally, the main blowing / vacuuming device and the matching air nozzle accessory are connected by a snap connection or a magnetic connection. In the process of implementing this application, the applicant found that the snap connection and the magnetic connection have the following problems:

[0205] When using snap-on or magnetic connections, it is difficult to ensure that the valve accessories have appropriate holding force or assembly torque. For example, when the snap-on fit is too tight, although it can provide sufficient assembly torque for the valve accessories, it also makes it difficult to disassemble. If the snap-on fit is loose, the gap between the two at the connection will be too large, and abnormal noise will easily occur.

[0206] Similarly, if the magnetic attraction of the magnetic connection design is too strong, it will make the nozzle accessories difficult to remove. If the magnetic attraction is too weak, it will not be able to resist the power of the air flow, and the nozzle accessories will easily fall off when the blowing power is high.

[0207] Accordingly, the applicant utilizes an air nozzle with a threaded interface and specifically provides an air nozzle accessory with a specific structural setting, so that a reliable and easy-to-load and unload connection is formed between the air nozzle accessory and the air pump, thereby effectively overcoming the defects of traditional snap connections and magnetic connections.

[0208] The following combination Figure 23 to Figure 25 Taking the first blowing nozzle accessory 2b1 as an example, the specific structural setting of the air nozzle accessory and the connection method of the air nozzle accessory and the air pump are described in detail.

[0209] like Fig.23 and Fig.24 As shown, the air valve accessory may include: an accessory body 201 , an accessory bracket 202 and a threaded connector 203 .

[0210] The accessory body 201 is a component that is hollow inside and open at both ends, through which gas can pass or flow, and the speed and pressure increase or decrease due to the change in the cross-sectional size of the accessory body 201.

[0211] The two end surfaces that are opposite to each other on the axis can be respectively referred to as the "working end surface S21" and the "joining end surface S22". The working end surface S21 is provided with an air outlet, while the joining end surface S22 is the end surface that is joined to the first end surface of the air pump.

[0212] Specifically, the engaging end surface may be configured to have a suitable size so that after the air nozzle fitting is assembled and fixed to the air pump, the first open end 31 of the air pump can be completely covered.

[0213] The accessory bracket 202 is fixed inside the accessory body 201. It provides a certain rigidity as a mounting support frame and forms a mounting position for the threaded connector 203. At least a part of the structure of the accessory bracket 202 is hollowed out to allow gas to pass through smoothly.

[0214] Specifically, the accessory bracket 202 can be fixedly connected to the accessory body 201 by any suitable type of fixed connection method, including but not limited to: ultrasonic welding, snap connection, adhesive connection or tight fit connection.

[0215] The threaded connector 203 is a reliable connection structure protruding from the accessory bracket 202. It has a size and shape that matches the inflation nozzle 21. The user can screw the gas nozzle accessory to form a threaded connection between the threaded connector 203 and the inflation nozzle 21.

[0216] In actual use, Fig.25 As shown, when the threaded connector 203 is fixedly connected to the inflation nozzle 21, the joint end face of the accessory body 201 will fit with the end face of the air pump 1, and the first open end 31 of the air pump will be completely covered in the accessory body 201, forming a continuous air duct, so that airflow is blown out of the air outlet of the working end face of the accessory body.

[0217] In some embodiments, in order to further improve the tightness of the connection between the air pump 1 and the air nozzle accessory 2, please continue to refer to Fig.24The contact area 33 where the first end surface of the air pump body 10 and the joint end surface of the accessory body 201 meet can be set to have a certain elastic deformation ability.

[0218] Therefore, when there is a mutual squeezing pressure between the accessory body 201 and the air pump body 10, the contact area with elastic deformation ability can fully fill the gap between the two by deformation, thereby providing better air tightness.

[0219] Specifically, the first end surface of the air pump body 10 may be provided with a contact area with elastic deformation in a variety of different ways. For example, the contact area of ​​the cover plate 1102 may be made of a soft rubber material using a two-color injection molding technique. Alternatively, a ring structure with elastic deformation capability may be made of a soft rubber material, and then fixed to the cover plate 1102 by a fixed connection method such as bonding, to form a contact area with elastic deformation capability.

[0220] It should be noted that although Figure 23 to Figure 25 Taking the first blowing nozzle accessory 2b1 as an example, the airtight connection between the nozzle accessory and the air pump body is described. However, based on the same inventive idea, Fig.21 The second blowing nozzle accessory 2b2, the third blowing nozzle accessory 2b3 and the suction nozzle accessory 2c shown can also adopt the same structural design and be airtightly connected to the air pump 1 through the same connection method.

[0221] Fig.26 This is a cross-sectional view of the second blowing nozzle accessory 2b2 provided in an embodiment of the present application. Fig. 27 This is a schematic structural diagram of the second blowing nozzle accessory 2b2 provided in an embodiment of the present application.

[0222] like Fig.26 and Fig. 27 As shown, the second blowing nozzle accessory 2b2 also has: an accessory body 201, an accessory bracket 202 and a threaded connector 203. It can be detachably fixedly connected to the air pump 1 by the same threaded connection method as the first blowing nozzle accessory 2b1.

[0223] Preferably, an additional concave-convex area 204 may be provided on the outer surface of the accessory body 201. The concave-convex area increases the friction between the user's fingers and the air nozzle accessory, so as to facilitate the screwing operation.

[0224] Please continue reading Fig. 27 The joint end surface S22 of the second blowing nozzle accessory 2b2 can maintain the same structure as the joint end surface of the first blowing nozzle accessory 2b1, so that the two blowing nozzle accessories have commonality and can be easily replaced.

[0225] Fig.28This is a cross-sectional view of the third blowing nozzle accessory 2b3 provided in an embodiment of the present application. Fig.29 This is a schematic structural diagram of the third blowing nozzle accessory 2b3 provided in an embodiment of the present application.

[0226] like Fig.28 and Fig.29 As shown, different from the air outlet design of the first air blowing nozzle accessory 2b1 and the second air blowing nozzle accessory 2b2, the air outlet of the third air blowing nozzle accessory 2b3 on the working end surface S21 is flat in shape, and can be more easily inserted into a smaller space.

[0227] Of course, the third blowing nozzle accessory 2b3 also has an accessory body 201, an accessory bracket 202 and a threaded connector 203, and forms the same joint end surface S22 as the second blowing nozzle accessory 2b2 to ensure the versatility of the air nozzle accessory.
