Description

Technical Field

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

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

[0003] However, the existing electric air pumps have relatively single functions and cannot well meet people's increasingly diverse usage needs. When other types of blowing or suction operations are required (such as blowing away fallen leaves and sucking air to evacuate a vacuum bag), other blowing and suction devices are often needed.

[0004] Therefore, there is an urgent need to provide an air pump that combines more functions and meets different usage requirements. Summary of the Utility Model

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

The first open end is opened on the surface of the air pump main body; the ventilation port is opened on the surface of the air pump main body and is located at a different position from the first open end; an air flow channel connecting the first open end and the ventilation port; the air flow channel is formed inside the air pump main body; and an air flow driving device housed inside the air pump main body. It is configured to perform one or more of the following functions: compressing the gas inhaled through the ventilation port and pumping it out from the inflation nozzle; driving the gas to enter from the first open end and leave from the ventilation port through the air flow channel; and driving the gas to enter from the ventilation port and leave from the first open end through the air flow channel.

[0007] Second aspect, an embodiment of 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 fitting; the air nozzle fitting includes: a fitting body; the interior of the fitting body is hollow and has a working end face and a joining end face facing away from each other; a fitting bracket fixed inside the fitting body; at least a part of the fitting bracket is hollowed out to allow gas to pass through the fitting body; a threaded connector fixed on the fitting bracket; the threaded connector protrudes from the fitting bracket; wherein, in response to the threaded connector being detachably threadedly connected to the air nozzle, the joining end face of the fitting body fits against the end face of the air pump body, and the fitting body covers the first open end of the air pump.

[0008] At least one advantage of the air pump and the air pump assembly provided by the embodiments of the present application is that: by adding additional air flow channels and related supporting structures, on the basis of the air inflation function of the air pump, it can also simultaneously have a blowing function and a suction function, thus more comprehensively meeting people's various usage needs, reducing the number of devices to be carried and improving the usage experience.

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

[0057] It should be noted that unless otherwise clearly specified and defined, the terms "center", "longitudinal", "transverse", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present application. The terms "installed", "connected", "connected", "fixed", etc. 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 only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features; the meaning of "a plurality" is two or more; "and / or" includes any and all combinations of one or more of the related listed items. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0059] I. Term Explanation:

[0060] "End face" refers to the surface formed at 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 quantifier indicating one or more. It can represent either a relatively small number or a relatively large number, aiming to illustrate the non-specificity in quantity and allowing the quantity to be adjusted according to needs in actual applications.

[0062] "Outer peripheral surface" refers to the continuous outer surface of an object or structure excluding the end faces at both ends. It constitutes the interface between the object or structure and the surrounding environment.

[0063] "Air flow channel" refers to a specific path or spatial structure within an object or structure for guiding and controlling 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 a structural element encloses a specific structural element or area in all or most directions. It forms a complete or nearly complete surrounding state without implying a specific shape.

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

[0066] "Inflation function" refers to the ability of a 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 applicable to application scenarios that require precise and relatively high pressures.

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

[0068] "Suction function" refers to the ability of a device to create a negative pressure or vacuum state to suck in and collect air, gas, or lightweight substances. It can be achieved by reversing the airflow direction of the blowing function and is applicable to application scenarios such as recovering variable containers and cleaning.

[0069] II. Regarding the inflator pump:

[0070] Figure 1 The following is a schematic structural diagram of the inflator pump provided by the embodiment of the present application from the front view. Figure 2 The following is a schematic structural diagram of the inflator pump provided by the embodiment of the present application from the back view. Figure 3 The following is a cross-sectional view of the inflator pump provided by the embodiment of the present application.

[0071] This inflator pump has the characteristic of multiple functions. In addition to providing the basic inflation function, it can also switch between the blowing function and the suction function to meet the usage requirements in different scenarios.

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

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

[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 openings 20 provided on the air pump body can cooperate with each other to enable gas exchange between the air inside the air pump body and the external air. Thus, through the gas exchange method, 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 above-mentioned ventilation openings 20 may include: an air intake 22 and a second opening end 32. The air intake 22 cooperates with the inflation nozzle 21 to achieve the inflation function, while the second opening end 32 cooperates with the first opening end 31 to achieve the blowing / suction function.

[0083] A heat dissipation hole is jointly formed between the air intake 22 and the second opening end 32, and the corresponding heat dissipation function is exerted through the gas exchange 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 on the air pump body 10 according to actual needs, and different effects can be obtained accordingly.

[0085] For example, as Figure 1 and Figure 2 shown, the air intake 22 can be arranged at the bottom of the holding part 12 to avoid unnecessary obstruction during the operation of the inflator. Or, please continue to refer to Figure 1 and Figure 2 , the second opening end 32 can be arranged on the outer peripheral surface of the main body part 11, 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 / suction effect.

[0086] Preferably, the above-mentioned first opening end 31 and the inflation nozzle 21 are arranged on the same end face of the air pump body. For example, as Figure 1 and Figure 2 shown, both the first opening end 31 and the inflation nozzle 21 are arranged on the first end face S11 of the air pump body. The inflation nozzle 21 is located at the center of the first end face S11, and the first opening end 31 is arranged around the inflation nozzle 21.

[0087] In this way, arranging the first opening end 31 and the inflation nozzle 21 on the same end face enables the openings required for the inflation function, the suction function, and the blowing function to be arranged on the same surface, thus bringing convenience to the operation of the user and also enabling a compact structural design.

[0088] Figure 3Exemplarily shown inside the air pump main body 10 is an air flow channel 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, not limited to Figure 3 as shown, as long as the connection between the first opening end 31 and the second opening end 32 can be achieved.

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

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

[0091] Thus, by further adding a new air flow driving device, a first opening end, a second opening end, and an air flow channel connecting the first opening end and the second opening end on the basis of a traditional inflator, the inflator can be equipped with inflation function, blowing function, and suction function, better meeting the needs of users for multi-purpose portable devices.

[0092] II. Regarding the air flow driving device:

[0093] Figure 4 This is a cross-sectional view of the inflator provided by the embodiment of the present application. In some embodiments, as Figure 4 shown, the air flow driving device may include: a first gas driving unit 41, a second gas driving unit 42, and an energy storage unit 43.

[0094] Among them, the first gas driving unit 41 is a power component designed to implement the blowing function and the suction function. Any suitable type of fan device can be selected according to actual needs (for example, a high-speed brushless motor with a built-in wind blade and a brushed high-speed motor with a wind blade installed at the output shaft end of the motor), as long as it can provide the driving force meeting the design requirements to drive gas to enter from the first opening end 31, leave from the second opening end 32 through the air flow channel, and drive gas to enter from the second opening end 32 and leave from the first opening end 31 through the air flow channel.

[0095] The second gas driving unit 42 is a power component designed to implement the inflation function. Similarly, any suitable type or model of air pump core (for example, a vane-type air pump core or a piston-type air pump core) can be selected according to actual needs, as long as it can provide the compression capacity to meet the design requirements, compress the gas inhaled by the compression suction port 22 and pump it out from the inflation nozzle 21 at the expected air pressure through the corresponding connecting pipe.

[0096] The energy storage unit 43 is a device capable of storing electrical energy in the form of chemical energy conversion. For example, a battery pack composed of several battery cells in series and / or parallel is used as the power source of the air pump to supply power to the first gas driving unit 41 and the second gas driving unit 42.

[0097] Specifically, in order to make reasonable use of space and provide an air pump body with a relatively small occupied volume and compactness as much as possible. Please continue to refer to Figure 4 and arrange the first gas driving unit 41 and multiple battery cells 431 in the main body part 11 while arranging the second gas driving unit 42 in the holding part 12.

[0098] Thus, the second gas driving unit 42 can compress the air inhaled from the suction port 22 at the end of the holding part 12 and pump the compressed air out from the inflation nozzle 21.

[0099] Alternatively, the arrangement positions of the above-mentioned first gas driving unit 41 and second gas driving unit 42 can also be interchanged. For example, arrange the first gas driving unit 41 in the holding part while arranging the second gas driving unit 42 in the main body part.

[0100] Furthermore, please continue to refer to Figure 4 and a more compact main body part 11 can also be provided by arranging the first gas driving unit 41 along the main axis and arranging multiple battery cells 431 around a part of the edge of the first gas driving unit 41.

[0101] Thus, the first gas driving unit 41 can provide a forward driving force or a reverse driving force to drive the air to flow in the air flow channel inside the main body part 11, so as to form negative pressure suction or blow out gas at the first opening end 31.

[0102] Alternatively, one of the above-mentioned first gas driving unit and second gas driving unit can be omitted. For example, when the gas driving unit has strong performance and can support a wide range of gas pressure regulation, the air flow driving device can also only include one gas driving unit and the 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 5 A 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 housed and fixed inside the main housing 111, and is a structural framework for fixing and supporting various functional components. In this application, the space formed by the main bracket 112 for fixing and accommodating functional components is called the installation position.

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

[0114] In addition, at least a part of the main bracket 112 has a physical connection with the main housing 111 to ensure that the main bracket 112 is fixed within the main housing 111. For example, as Figure 3 shown, a part of the main bracket 112 can be snap-fitted with the main housing 111 through the first snap B01, so that the main bracket 112 is fixedly connected to the main housing 111.

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

[0116] Moreover, these ventilation holes 1123 give the main bracket 112 a hollow structural design, and can also play the role of reducing the physical weight of the main bracket 112.

[0117] Specifically, as Figure 7 and Figure 8 shown, the main bracket 112 can include a first bracket end 1121a, a second bracket end 1121b, and a spacer structure 1122 located between the first bracket end and the second bracket end.

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

[0119] Multiple mutually spaced battery cells 431 can be connected in series or in parallel through electrical connectors 44 to form a complete energy storage unit to provide and output the required voltage.

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

[0121] Preferably, as Figure 6 shown, a shock pad 53 can also be clamped between the inflation nozzle 21 and the cover plate 1102. The shock pad 53 is made of an elastic material (for example, soft rubber or other flexible materials), and is sleeved on the outer periphery of the inflation nozzle 21, so as to form an elastic buffer layer between the inflation nozzle 21 and the cover plate 1102. Based on the buffer layer formed by the shock pad 53, noise generated by the mutual vibration and collision of the two can be avoided during inflation.

[0122] In some other embodiments, please continue to refer to Figure 7 , the first open end 31 can also be provided at the first bracket end 1121a, which is realized by a central hole opened in the first bracket end 1121a. Correspondingly, a grille 1104 is provided in the position area of the cover plate 1102 opposite to the central hole of the first bracket end 1121a to guide the gas to smoothly pass through the first open end 31.

[0123] Preferably, as Figure 1 shown, the grille 1104 can be composed of a plurality of blade structures presenting a radial shape. These blade structures extend outward from the central inflation nozzle, and the extension direction is inclined at a certain angle and not completely straight.

[0124] Thus, when the air flow passes through the grille 1104, the inclined blade structure can guide the air flow to generate a rotational movement, so that the air flow can be more evenly distributed over the entire first open end 31, effectively improving the uniformity of the air flow and reducing the air flow noise.

[0125] IV. Regarding the holding part 12 of the air pump body:

[0126] In some embodiments, please continue to refer to Figure 5 , the holding part 12 can be composed of a holding inner cover 121, a holding outer cover 122, a terminal connecting ring 123, and a holding foot pad 124.

[0127] Among them, the holding inner cover 121 is a housing component that surrounds and houses the second gas driving unit 42. It provides an internal space adapted to the second gas driving unit 42.

[0128] Exemplarily, Figure 5As shown in the figure, a part 121a of the holding inner cover 121 is integrally formed with the main body part 111, and another independent part 121b of the holding inner cover 121 is fixedly connected to the integrally formed part 121a by a screw 92.

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

[0130] The holding outer cover 122 is sleeved outside the holding inner cover 121 to form the main outer surface of the holding part 12. The end connecting ring 123 can be a mesh structure (for example, a ring-shaped metal mesh) provided with a plurality of through holes to form the above-mentioned air inlet 22.

[0131] The end connecting ring 123 can be locked and fixed on the holding inner cover 121 by any suitable type of fixed connection means such as screws. Thus, the end connecting ring 123 can play a role in restricting the holding outer cover 122 from coming off, and its position is also fixed together. The holding foot pad 124 is fixedly covered at the bottom end of the end connecting ring 123 to form a complete holding part 12.

[0132] V. Regarding the main bracket:

[0133] Figure 9 It is a schematic exploded view of the main bracket provided by the embodiment of the present application. As Figure 9 shown, the main bracket 112 can be composed of a first battery cell bracket 112a and a second battery cell bracket 112b.

[0134] The first battery cell bracket 112a and the second battery cell bracket 112b have a mutually paired structural design, and the two are fixedly connected by any suitable type of fixed connection means ( Figure 9 exemplarily shown in the figure as being fixedly connected by a screw 91) to form the main bracket 112.

[0135] Among them, the first battery cell bracket 112a includes: a first bracket end 1121a and a first spacer structure 1122a. Similarly, the second battery cell bracket 112b includes: a second bracket end 1122b and a second spacer structure 1122b.

[0136] The first spacer structure 1122a and the second spacer structure 1122b respectively provide a mounting hole H1 on the main axis and a plurality of battery cell slots H2 arranged circumferentially along the mounting hole ( Figure 9 exemplarily shown in the figure as having 3 battery cell slots). The mounting hole H1 and each battery cell slot H2 are holes spaced apart from each other.

[0137] Thus, when the first battery cell bracket 112a and the second battery cell bracket 112b are fixedly connected such that the two ends of the first spacer structure 1122a and the second spacer structure 1122b are joined to each other, the mounting holes formed by the two spacer structures will cooperate to form the above-mentioned first mounting position for mounting and placing the first gas driving unit 41. The correspondingly formed battery cell slots of the two spacer structures will cooperate to form the above-mentioned second mounting position for mounting and placing the battery cell 431.

[0138] Alternatively, when the battery cell and the first gas driving unit have specific axial lengths, the first spacer structure 1122a and the second spacer structure 1122b may not be joined to each other and there may be a certain gap, as long as it is ensured that the battery cell and the first gas driving unit can be stably clamped and fixed between the first battery cell bracket 112a and the second battery cell bracket 112b.

[0139] Specifically, both the first mounting position and the second mounting position formed in the main bracket 112 are arranged along the axial direction of the air pump body. Thus, the battery cell 431 assembled and fixed in the second mounting position is also arranged along the same axial direction, thereby stabilizing the center of gravity of the entire air pump body, facilitating the holding of the inflator pump, and effectively enhancing the user experience of the inflator pump.

[0140] VI. Regarding the lighting function of the inflator pump:

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

[0142] Thus, when the lighting device 60 is lit, it can emit light to illuminate the area in front of the first end face S11 of the inflator pump. Such a design also facilitates the user to establish a connection between other accessories and the inflating nozzle or the first opening end provided on the first end face S11 in a dark environment.

[0143] Specifically, please continue to refer to Figure 5 , the lighting device 60 may include: a lamp board 61 and a lamp shade 62.

[0144] Among them, the lamp board 61 is fixed to the first bracket end 1121a and is disposed around the first opening end 31. The lamp shade 62 has a size adapted to the lamp board 61, and it is fixedly connected to the cover plate 1102 and sleeved on the lamp board 61 to protect the lamp board 61 and concentrate the light.

[0145] Exemplarily, Figure 5 shows a ring-shaped lamp board 61 and a lamp shade, but those skilled in the art can understand that other lamp boards and lamp shades of any suitable shape or size may also be used according to actual needs.

[0146] In addition, Figure 5 it is also shown that the lamp board 61 is fixed to the end of the bracket of the main bracket 112 by means of screwing with screws 93, and the lamp cover 62 is fixed to the cover plate 1102 by means of snap connection. However, those skilled in the art can understand that any other suitable type of fixed connection method can also be used to achieve the fixed connection between the lamp board, the lamp cover, the cover plate and the bracket end.

[0147] Alternatively, other similar structures can also be used to implement the above lighting device 60, not limited to Figure 5 the shown situation. For example, the cover plate 1102 and the lamp cover 62 are directly formed into a complete structure, and the function of the annular lamp cover is realized by setting corresponding transparent areas on the cover plate 1102.

[0148] VII. Interaction components of the air pump:

[0149] In some embodiments, please continue to refer to Figure 2 , the air pump further includes: a plurality of interaction components 70 provided on the second end face S12 of the air pump body.

[0150] The interaction component 70 is a functional component that realizes the interaction between the user and the air pump. As a bridge for information transmission, it enables the user to input data, issue instructions and obtain feedback information of the air pump. For example, as Figure 13 shown, the interaction component 70 may include a display area 71 that feeds back information in a visual form and control buttons 72 that receive the user's input data and instructions.

[0151] Specifically, as Figure 11 shown, both the display area 71 and the control buttons 72 can be implemented by a circuit component 80 fixed to the end of the second bracket 1121b.

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

[0153] In some embodiments, as Figure 12 shown, an appropriate gap R1 can be reserved between the circuit component 80 fixed to the end of the second bracket 1121b and the second spacer structure 1122b, so that 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, users can conveniently control and operate the air pump, easily switch between multiple functions, and effectively improve the user experience.

[0155] VIII. Interaction process of the air pump:

[0156] Figure 13 It is a schematic diagram of the control button 72 provided in an embodiment of the present application. Figure 14 It is a schematic diagram of the display area 71 provided in an embodiment of the present application. The following combines Figure 13 and Figure 14 to describe in detail the interaction process between the user and the air pump when using the air pump.

[0157] In some embodiments, as Figure 13 shown, the control button 72 is set as: start button 721, mode selection button 722, lighting function button 723, air pressure increase button 724, and air pressure decrease button 725.

[0158] As Figure 14 shown, in the display area 71, there is a first visual content 711 for displaying the air pressure unit, a second visual content for displaying the air pressure value, and a third visual content for displaying various inflation modes, blowing modes, and suction modes.

[0159] Among them, the air pressure unit in the first visual content 711 is set as 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 respectively uses different icons to vividly represent: 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) Air pump shutdown / startup:

[0161] When the air pump is in the shutdown state, the display area 71 is turned off and no feedback information is shown. 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 make the air pump enter the startup state. After the air pump is started up, the interaction interface shown in Figure 14 will be presented in the display area 71.

[0162] 3) Air pressure unit selection:

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

[0164] 4) Air pressure increase and decrease adjustment:

[0165] After the air pump is turned on, the user can also increase the air pressure setting value by briefly pressing the air pressure increase button 724, and decrease the air pressure setting value by briefly pressing the air pressure decrease button 725. The display area 71 will show the current air pressure setting value 712b in real time according to the user's operation.

[0166] 5) Inflation mode selection:

[0167] The above four inflation modes are pre-set in the air pump to facilitate the user to quickly adjust, reduce the operation frequency and times. For different mode usage scenarios, default inflation parameters are set.

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

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

[0170] 6) Free inflation mode:

[0171] After the air pump is turned on and started, the user can also enter the free inflation mode by briefly pressing the start button 721 once. 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 to control the cycle switching among three different states: lighting - flashing - extinguishing. After the air pump is turned on and started, the user first briefly presses the lighting function button 723 to start the lighting function of the air pump. At this time, the lighting device on the first end face of the air pump body is lit to play a lighting role. Then, on this basis, briefly press the lighting function button 723 again, and the air pump will switch to the flashing function. At this time, the lighting device 60 flashes at a set frequency to play a role in calling for rescue. Finally, briefly press the lighting function button 723 again in the flashing state, and the lighting function will be turned off. At this time, the lighting device goes out.

[0174] 8) Blowing / Suction Function:

[0175] After the air pump is powered on and starts up, the user can switch between the above-mentioned blowing mode, suction mode, and four inflation modes by pressing the mode selection button 722 briefly. Similarly, the icon corresponding to the currently selected mode will be lit, and the icons of the unselected modes will not be displayed to feedback the current working state of the air pump to the user.

[0176] IX. Assembly Process of the Air Pump:

[0177] The following takes Figure 6 the schematic diagram of the disassembled structure of the air pump shown as an example, combined with Figure 5 , Figure 9 and Figure 12 , to describe the assembly process of the air pump in detail.

[0178] Assembly Process of the Main Bracket:

[0179] As shown in Figure 9 , the battery cell 431 and the first gas driving unit 41 are respectively installed into the corresponding mounting holes H1 in the first battery cell bracket 112a and the battery cell slot H2 in the second battery cell bracket 112b. Then, use the screw 91 to lock and fixedly connect the first battery cell bracket 112a and the second battery cell bracket 112b.

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

[0181] Thus, the main bracket with the battery cell and the first gas driving unit installed, as shown in Figure 7 and Figure 8 , is assembled.

[0182] As shown in Figure 12 , use the screw 94 to fix the first circuit main board 81 to the second bracket end of the second battery cell bracket 112b where the second negative nickel sheet 443 and the second connecting nickel sheet 444 have been welded, and use the screw 95 to lock and fix the second circuit main board 82 and the screen bracket 83 together. Finally, use the screw 96 to stack and fix the second circuit main board 82 and the screen bracket 83 that have been locked and fixed together on the first circuit main board 81 that has been fixed to the second battery cell bracket 112b, and sleeve the shock pad 53 on the inflation nozzle 21.

[0183] Thus, the assembled product is obtained as shown in Figure 10 andFigure 11 As shown, the main bracket installed with shock pads and circuit components.

[0184] As Figure 6 shown, after one end of the air pipe 51 is connected to the compressed air output end of the second gas driving unit 42, the two are assembled into the interior of the main housing 111 simultaneously. Subsequently, the other end of the air pipe 51 is connected to the inflation nozzle 21 provided on the first battery cell bracket 112a, and the main bracket 111 installed with shock pads and circuit components is inserted into the housing body 1101 through the open end of the housing body 1101.

[0185] At this time, a plurality of buckles provided at the open end of the housing body 1101 in the circumferential direction are engaged with the paired buckle grooves on the first battery cell bracket 112a, so that the main bracket 112 is fixed within the housing body 1101.

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

[0187] As Figure 5 shown, screws 92 are used to lock and fix the independent part 121b of the inner grip cover to the integrally formed part 121a of the inner grip cover 121 to form a complete inner grip cover 121.

[0188] Then, after the outer grip cover 122 and the end connecting ring 123 are sequentially sleeved on the inner grip cover 121, in a way of locking and fixing with screws, the end connecting ring 123 is locked and fixed on the inner grip cover 121, and the grip foot pad 124 is sleeved and fixed at the bottom opening of the end connecting ring 123 to complete the assembly of the grip part.

[0189] Please continue to refer to Figure 5 , the connecting ring 1103 is assembled to the open end of the housing body 11, and the cover plate 1102 is covered and fixed to the end of the main bracket 112.

[0190] Specifically, as Figure 18 shown, the cover plate 1102 and the first battery cell bracket 112a are engaged with each other through the second buckle B02, and the fixed connection between the two is realized through the buckle connection method. The second buckle B02 can be set to be multiple and evenly arranged in the circumferential direction of the cover plate and the first battery cell bracket 112a.

[0191] Then, the lamp board 61 is installed into the lamp slot formed by the cover plate 1102, and in a way of locking and fixing with screws, the lamp board 61 and the cover plate 1102 are fixed together at the bracket end of the main bracket.

[0192] Finally, the lampshade 62 is detachably and fixedly connected by snap connection or the like, and is snap-fixed above the lamp slot of the cover plate 1102, so that it covers the lamp board 61, completing the assembly of the main body part.

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

[0194] When the air pump performs the inflation function: As Figure 15 and Figure 16 shown, the external air is inhaled into the interior of the holding part 11 through the suction port 22. After being compressed by the second gas driving unit 42 housed in the holding part 11, the compressed gas is output from the top of the second gas driving unit 42, and after passing through the trachea 51 bent approximately 90°, it reaches the inflation nozzle 21 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, as Figure 17 and Figure 18 shown, driven by 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 open end 32 formed by the connecting ring 1103. Subsequently, it enters the internal air duct at the first installation position through the gap between the second spacer structure and the circuit assembly 80. Finally, it is accelerated and blown out from the first open end 31 formed at the end of the first bracket.

[0196] When the air pump performs the suction function, as Figure 19 and Figure 20 shown, the first gas driving unit 41 provides a reverse driving force, so that the external air enters the internal air duct at the first installation position through the first open end 31. Subsequently, it enters the space between the main housing 111 and the main bracket 112 through the gap between the second spacer structure and the circuit assembly 80. Finally, it leaves the main body part 11 from the second open end 32 formed by the connecting ring.

[0197] XI. Connection method between the air pump and the nozzle fitting:

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

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

[0200] Figure 22 Schematic diagram of an air pump assembly provided by another embodiment of the present application. It shows various nozzle accessories used in the blowing function and the suction function, in addition to the external air pipe used in the inflation function.

[0201] As Figure 22 shown, the nozzle accessories include: three blowing nozzle accessories with different outlet diameter specifications and a suction nozzle accessory 2c. Of course, those skilled in the art can also select and set other more numbers or specifications of nozzle accessories according to actual needs, which are not specifically limited here.

[0202] In the present application, for the sake of simplicity of description, the blowing nozzle accessory with the largest outlet diameter is called "the first blowing nozzle accessory 2b1", the blowing nozzle accessory with the 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 for larger blowing objects (such as inflatable beds and inflatable boats). The second blowing nozzle accessory 2b2 can be used in scenarios for some medium and small blowing objects (such as household inflatable pillows and inflatable mattresses). The third blowing nozzle accessory 2b3 is used in scenarios for small blowing objects (such as swimming rings and small inflatable dolls) or blowing for cleaning. The suction nozzle accessory 2c can be used in scenarios for the rapid recovery of blowing objects or the evacuation of vacuum bags. It can quickly extract the residual air inside the suction object to reduce its occupied volume.

[0204] Traditionally, a detachable connection method such as snap connection or magnetic attraction connection is adopted between the blowing / suction main device and the supporting nozzle accessories. During the implementation of the present application, the applicant found the following problems with snap connection and magnetic attraction connection:

[0205] When using snap connection or magnetic attraction connection, it is difficult to ensure that the nozzle accessory has an appropriate holding force or assembly torque. For example, when the snap fit is too tight, although it can provide sufficient assembly torque for the nozzle accessory, it also causes the problem of difficult disassembly. If the snap fit is loose, it will result in a large gap at the connection between the two and is prone to abnormal noise.

[0206] Similarly, if the magnetic attraction force in the magnetic attraction connection design is too large, it will be difficult to disassemble the nozzle accessory. Once the magnetic attraction force is too small, it cannot resist the power of the air flow and is prone to cause the nozzle accessory to fall off when the blowing power is large.

[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-assemble and unassemble 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 Figures 23 to 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 Figure 23 and Figure 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, Figure 25As shown, when the threaded connector 203 is fixedly connected to the inflating nozzle 21, the joint end face of the fitting body 201 will be in contact with the end face of the air pump 1, and the first open end 31 of the inflating pump is completely covered within the fitting body 201, forming a continuous air duct, such that there is an air flow blowing out from the air outlet of the working end face of the fitting body.

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

[0218] Thus, when there is a mutual extrusion pressure between the fitting body 201 and the air pump body 10, the contact area with elastic deformation ability can fully fill the gap between the two through deformation, providing better airtightness.

[0219] Specifically, the contact area with elastic deformation ability can be set on the first end face of the air pump body 10 in a variety of different ways. For example, using two-color injection molding technology, the contact area of the cover plate 1102 is made of a soft rubber material. Or, after making an annular structure with elastic deformation ability using a soft rubber material, it is fixed to the cover plate 1102 through a fixed connection method such as bonding, to form a contact area with elastic deformation ability.

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

[0221] Figure 26 This is a cross-sectional view of the second blowing nozzle fitting 2b2 provided by the embodiment of the present application. Figure 27 This is a structural schematic diagram of the second blowing nozzle fitting 2b2 provided by the embodiment of the present application.

[0222] As Figure 26 and Figure 27 shown, the second blowing nozzle fitting 2b2 also has: a fitting body 201, a fitting bracket 202, and a threaded connector 203. It can be detachably fixedly connected to the air pump 1 through the same threaded connection method as the above-mentioned first blowing nozzle fitting 2b1.

[0223] Preferably, additional concave-convex regions 204 may be provided on the outer surface of the fitting body 201. The concave-convex regions increase the friction between the user's finger and the nozzle fitting, facilitating the screwing operation.

[0224] Please continue to refer to Figure 27 , the joint end face S22 of the second blowing nozzle fitting 2b2 may have the same structure as the joint end face of the first blowing nozzle fitting 2b1, so that the two blowing nozzle fittings are universal and can be conveniently replaced and used.

[0225] Figure 28 FIG. is a cross-sectional view of the third blowing nozzle fitting 2b3 provided by an embodiment of the present application. Figure 29 FIG. is a schematic structural view of the third blowing nozzle fitting 2b3 provided by an embodiment of the present application.

[0226] As Figure 28 and Figure 29 shown, different from the outlet designs of the first blowing nozzle fitting 2b1 and the second blowing nozzle fitting 2b2, the outlet of the third blowing nozzle fitting 2b3 on the working end face S21 is flat, and it can be inserted into a smaller space more conveniently.

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

[0228] Figure 30 FIG. is a cross-sectional view of the suction nozzle fitting 2c provided by an embodiment of the present application. Figure 31 FIG. is a schematic structural view of the suction nozzle fitting 2c provided by an embodiment of the present application. Figure 32 FIG. is an exploded structural view of the suction nozzle fitting 2c provided by an embodiment of the present application.

[0229] As Figure 30 and Figure 31 shown, the suction nozzle fitting 2c also has a fitting body 201, a fitting bracket 202, and a threaded connector 203, and forms the exactly same joint end face S22 as the first blowing nozzle fitting 2b1, the second blowing nozzle fitting 2b2, and the third blowing nozzle fitting 2b3 to ensure the universality among any nozzle fittings.

[0230] Different from the blowing nozzle fitting, the suction nozzle fitting forms a suction port on the working end face S21. It can form a local negative pressure to achieve the function of sucking air.

[0231] In some embodiments, the suction nozzle fitting 2c may also be designed as a detachable separating component to achieve effects such as facilitating component replacement and improving adaptability. AsFigure 32 As shown, the fitting body 201 may include: a first part 201a and a second part 201b.

[0232] Among them, the first part 201a and the second part 201b are two detachable and connected independent components. The fitting bracket 202, the threaded connector 203, and the concave-convex area 204 are arranged on the first part 201a, and the second part 201b forms a working end face S21, which is provided with a suction port.

[0233] Thus, the user can independently replace the second part 201b according to the actual situation while keeping the first part 201a unchanged to meet the requirements of different scenarios. Or, the first part 201a and the second part 201b can be disassembled to facilitate cleaning of components such as the filter screen or the sealing ring in the suction nozzle fitting 2c.
