[0068] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0069] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0070] It should also be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or may be connected to an intermediary component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through an intermediary component.

[0071] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0072] like Figure 1 and Figure 2 As shown, the air pumping device provided in this embodiment includes an air pump 10, a blower 20, and a motor 30.

[0073] The motor 30 is driven by the blower 20, and the motor 30 is driven by the air pump 10. The air pump 10 and the blower 20 are driven by the same motor 30.

[0074] It should be noted that this application uses only one motor 30 to drive the air pump 10 and the blower 20. Furthermore, the motor 30 can drive both the air pump 10 and the blower 20 simultaneously, or it can drive each of them separately. That is, the motor 30 can drive the air pump 10 independently while the blower 20 remains stationary, or the motor 30 can drive the blower 20 independently while the air pump 10 remains stationary.

[0075] In this embodiment of the air pump and blower, both the air pump 10 and the blower device 20 are driven by the same motor 30 during inflation and / or blowing. Therefore, compared to the prior art, this reduces the space occupied by the additional motor 30, allowing for a smaller outer casing 40, thus reducing the size and weight of the air pump and blower, making it easier to carry and use. For example, in practical applications, the air pump and blower can be used as an emergency device in a car, and therefore, it is generally placed in the car for extended periods. Reducing the size and weight of the air pump and blower makes it more convenient for carrying and emergency use in the car.

[0076] like Figure 1 and Figure 2 As shown, the air pumping device provided in this embodiment includes an air pump 10, a blower 20, a motor 30, and a housing 40.

[0077] The air pump 10, the blower device 20, and the motor 30 are all housed inside the housing 40. The housing 40 has a first interface 51 and a second interface 52. The first interface 51 is used to receive the blower device externally, and the second interface 52 is used to receive the inflation device externally. The first interface 51 includes an air outlet 51a, and the second interface 52 includes an air outlet 52a. The air outlet 51a is connected to the blower device 20 to supply air to the blower device 20, and the air outlet 52a is connected to the air pump 10 to supply air to the air pump 10.

[0078] It is important to understand that when the air pump 10 inflates the device to be inflated through the second interface 52, it can inject high-pressure gas into the device. Therefore, the device to be inflated is generally a device that requires high-pressure gas, such as a car tire. When the blower device 20 blows air into the device to be blown through the first interface 51, it can quickly inject a large amount of gas into the device. Therefore, the device to be blown is generally a device that requires a large amount of gas, such as an air mattress. This application can choose to use either the air pump 10 or the blower device 20, or both, depending on the application scenario.

[0079] It should be noted that the first interface 51 and the second interface 52 of this application can be a combined interface, or the first interface 51 and the second interface 52 can be independent interfaces.

[0080] In this embodiment of the air pump and blower, the air pump 10 can inflate the device to be inflated through the second interface 52, and the blower 20 can blow air onto the device to be inflated through the first interface 51. By housing the air pump 10, the blower 20, and the motor 30 within the housing 40, the space occupied by the additional motor can be reduced, thereby shrinking the housing and reducing the size and weight of the air pump and blower, making it easier to carry and use.

[0081] like Figure 1 and Figure 2 As shown in the embodiment of this application, the blower 20 and the air pump 10 are arranged sequentially along the first direction a. The first direction a is the direction in which the length of the housing 40 extends. This arrangement allows the blower 20 and the air pump 10 to be more compactly housed within the housing 40, which is beneficial for structural integration within the housing 40 and further miniaturizes the air pump, making it easier to carry and use.

[0082] like Figure 1 and Figure 2 As shown in this embodiment, the outer casing 40 has a first interface 51 at its end along the first direction a, and a blower channel 40b is provided between the air pump 10 and the inner wall of the outer casing 40. The blower device 20 is connected to the air outlet 51a through the blower channel 40b. It can be understood that there is a certain distance between the first interface 51 and the blower device 20, and the blower channel 40b can guide the air discharged by the blower device 20. This facilitates the directional airflow of the blower device 20. Furthermore, since the blower channel 40b directly utilizes the space between the blower device 20 and the inner wall of the outer casing 40, it does not additionally occupy the space of the air pump. It should be noted that in this embodiment, the blower channel 40b can be a pipe provided between the air pump 10 and the inner wall of the outer casing 40, or it can be a channel formed by the space between the air pump 10 body and the inner wall of the outer casing 40.

[0083] For example, the space between the body of the air pump 10 and the inner wall of the housing 40 forms at least a partial air passage 40b. In this way, on the one hand, the structure of the air pump and blower can be simplified and its weight reduced for easy carrying; on the other hand, when the blower 20 discharges air along the air passage 40b, the air in the air passage 40b can also enter directly from the air inlet of the air pump 10. Therefore, this arrangement is also beneficial for the air pump 10 to discharge air.

[0084] like Figure 1 and Figure 2 As shown in the embodiment of this application, the outer casing 40 has an air inlet 40a at its first end along the first direction a. It should be noted that since the blower 20 and the air pump 10 are arranged sequentially along the first direction a, the air inlet of the blower 20 is close to the air inlet 40a, thus facilitating the introduction of outside air into the air-blowing equipment. Combined with the aforementioned first connection located at the end of the outer casing 40 along the first direction a, the air inlet and outlet of the blower 20 are arranged along the length of the outer casing 40. Under the guidance of the blower 20, the air can flow rapidly along the first direction a. This is more conducive to the air outlet of the blower 20, so as to provide a large amount of gas to the equipment being blown.

[0085] like Figure 1 and Figure 2 As shown in the embodiment of this application, the outer casing 40 has a second interface 52 at its end along the first direction a. Air flows in through the air inlet 40a, and gas can enter from the air inlet of the air pump 10. Under the operation of the air pump 10, high-pressure gas is discharged from the second interface 52 to provide high-pressure gas to the device to be inflated. It should be noted that in this application, the air from the outside can be accelerated into the air pump 10 by the guide of the blower 20 to improve the inflation efficiency. Of course, when the blower 20 is not working, the outside gas can also pass through the blower 20, for example, through the impeller of the blower 20, and then through the blower through hole 60b of the air duct component 60, flowing into the blower channel 40b to enter the air pump 10, so as to realize the inflation of the air pump 10. In addition, the first interface 51 and the second interface 52 are both located at the end of the outer casing 40, which makes it convenient for the user to connect the device to be inflated and / or the device to be inflated for use.

[0086] like Figure 1 and Figure 2 As shown in the embodiment of this application, the motor 30 is located between the air pump 10 and the blower 20. The motor 30 can be close to both the blower 20 and the air pump 10, facilitating a more convenient drive connection between the motor 30, the air pump 10, and the blower 20. The structural connection is simple, requiring no additional lengthening of the drive shaft, making the air pump device more compact and rational in structure. Furthermore, this arrangement allows the blower 20 to be closer to the air inlet 40a, facilitating the blower 20 to guide outside air into the air pump device. It can be understood that with this arrangement, the air pump 10, motor 30, and blower 20 are sequentially arranged along the first direction a, and the overall structure better fits the shape of the outer casing 40, further miniaturizing the air pump device for easier carrying and use. Of course, in other embodiments, the motor 30 may also be located on the side of the blower 20 away from the air pump 10. For example, the output shaft of the motor 30 may be connected to the second drive shaft of the blower 20, which in turn may be connected to the first drive shaft of the air pump 10. In this way, the motor 30 can drive the blower 20 and the air pump 10 to operate, thereby achieving air output and ventilation.

[0087] like Figure 1 and Figure 2 As shown in the embodiment of this application, one end of the motor 30 is provided with a first output shaft (not shown), and the other end of the motor 30 is provided with a second output shaft (not shown). The first output shaft is used to drive the air pump 10, and the second output shaft is used to drive the blower device 20. In this way, the motor 30 can drive the blower device 20 and the air pump 10 to operate, so as to realize air output and airflow.

[0088] In some embodiments, a clutch device is provided between the first output shaft of the motor 30 and the first drive shaft of the air pump 10, and a clutch device is also provided between the second output shaft of the motor 30 and the second drive shaft of the blower 20. Thus, the user can, as needed, individually close the clutch device between the first output shaft of the motor 30 and the first drive shaft of the air pump 10 to drive the air pump 10 alone; or individually close the clutch device between the second output shaft of the motor 30 and the second drive shaft of the blower 20 to drive the blower 20 alone; or simultaneously close the clutch devices at both ends of the motor 30 to allow the motor 30 to simultaneously drive both the air pump 10 and the blower 20.

[0089] In some embodiments, a clutch device is provided between the first output shaft of the motor 30 and the first drive shaft of the air pump 10, and the second output shaft of the motor 30 and the second drive shaft of the blower 20 are directly connected. Thus, the user can close the clutch device between the first output shaft of the motor 30 and the first drive shaft of the air pump 10 as needed, so that the motor 30 can simultaneously drive the air pump 10 and the blower 20; or, the clutch device can be left undone to drive the blower 20 alone.

[0090] In some embodiments, the first output shaft of the motor 30 and the first drive shaft of the air pump 10 are directly connected, and a clutch device is provided between the second output shaft of the motor 30 and the second drive shaft of the blower 20. Thus, the user can close the clutch device between the second output shaft of the motor 30 and the second drive shaft of the blower 20 as needed, so that the motor 30 can simultaneously drive both the air pump 10 and the blower 20; alternatively, the clutch device can be left undone to drive the air pump 10 alone.

[0091] For example, the clutch device includes an electromagnetic friction clutch. The electromagnetic friction clutch includes an input end, an output end, an electromagnetic plate, a friction plate, and an armature. The electromagnetic plate and the friction plate are disposed on the input end, which is connected to the output shaft. The armature is disposed on the output end, which is connected to the drive shaft. When the electromagnetic friction clutch is not energized, the input end and the output end are disconnected, and torque cannot be transmitted. When the electromagnetic friction clutch is energized, the armature is attracted to the friction plate by the electromagnetic plate, and torque can be transmitted between the input end and the output end, so that the output shaft of the motor 30 drives the corresponding drive shaft. Of course, the clutch device can also be other types of clutches, which will not be elaborated here.

[0092] like Figures 1 to 3As shown in the embodiment of this application, the air compressor also includes a duct component 60. The duct component 60 has a mounting hole 60a, and at least one of the blower 20, motor 30, and air pump 10 is fixed to the mounting hole 60a. The duct component 60 securely mounts at least one of the blower 20, motor 30, and air pump 10. Furthermore, the duct component 60 serves as an internal air guide structure for the air compressor, facilitating the air output of the blower 20 and the air output of the air pump 10. It should be noted that the duct component 60 can be used to fix one of the blower 20, motor 30, and air pump 10 individually, or simultaneously to fix two or more of them, as long as the duct component 60 ensures smooth air output from the blower 20 and the air output from the air pump 10.

[0093] like Figure 2 and Figure 3 As shown, exemplarily, the periphery of the air duct component 60 is adapted to and snapped into the inner wall of the housing 40, so that the air duct component 60 can be securely installed to provide stable support for at least one of the installed blower 20, motor 30 and air pump 10.

[0094] like Figures 1 to 3 As shown, exemplarily, the mounting hole 60a is located at the center of the air duct component 60 in the housing 40 perpendicular to the first direction a. This allows at least one of the blower 20, motor 30, and air pump 10 to be securely mounted in the center of the housing 40, facilitating the overall centered placement of the blower 20, motor 30, and air pump 10 within the housing 40. In particular, it ensures that the impeller of the blower 20 is centered, resulting in a compact and integrated arrangement of the blower 20 within the housing. In this example, the air inlet 40a, air outlet 52a, and air outlet 51a are also located at the center of the housing 40 perpendicular to the first direction a, facilitating stable and balanced airflow from the air pump.

[0095] like Figure 2 and Figure 3 As shown, exemplarily, the mounting hole 60a of the air duct component 60 secures the motor 30. When the motor 30 is located between the blower 20 and the air pump 10, the motor 30 can be firmly engaged within the mounting hole 60a, ensuring stable drive of the air pump 10 and / or the blower 20. In this example, one end of the motor 30 is adapted to the mounting hole 60a to achieve a secure mounting of the motor 30.

[0096] like Figures 1 to 3As shown in the embodiment of this application, the air-blowing device further includes an air duct component 60, which has an air-blowing through hole 60b. The blower device 20 has an air outlet, which is connected to the air outlet 51a through the air-blowing through hole 60b. The air duct component 60 can guide the air outlet of the blower device 20, thereby facilitating air outlet for the blower device and improving the blowing efficiency.

[0097] like Figure 2 and Figure 3 As shown, exemplarily, the blower through-hole 60b is arranged around the outer periphery of the air duct component 60. This allows the blower through-hole 60b to be positioned opposite the air outlet of the blower device 20, facilitating the guidance of airflow from the blower device 20. Specifically, the blower device 20 is arranged around the mounting hole 60a. In this way, the air duct component 60 can both stabilize the internal structure of the air pump and guide the airflow from the blower device 20, thereby improving the blowing efficiency.

[0098] like Figure 1 and Figure 2 As shown in the embodiment of this application, the blower 20, motor 30, and air pump 10 are sequentially arranged along the first direction a. The air duct component 60 is located near the blower 20. The mounting hole 60a is used to fix the end of the motor 30 near the blower 20, so that the second output shaft of the motor 30 can stably support and drive the blower 20 to move. A blower through-hole 60b is arranged around the mounting hole 60a. One end of the blower through-hole 60b is connected to the air outlet of the blower 20, and the other end is connected to the blower channel 40b formed between the motor 30, air pump 10, and the inner wall of the housing 40. Thus, the air outlet of the blower 20 is sequentially connected to the air outlet 51a through the blower through-hole 60b and the blower channel 40b. Figure 2 As shown, when the blower 20 is running, the air it discharges can pass through the blower through hole 60b, the blower channel 40b and the air outlet 51a to realize the air outlet of the blower 20.

[0099] like Figure 1 and Figure 4 As shown in the embodiment of this application, the blower 20 includes an impeller, and a motor 30 is connected to the impeller to drive the impeller to rotate. With the rotation of the impeller, air in the inlet of the blower 20 can be guided to the outlet to achieve air output.

[0100] like Figure 1 and Figure 4 As shown in the embodiment of this application, the drive shaft of the impeller extends along the first direction a. This allows the impeller to discharge air along the first direction a. Combined with the above embodiment, this allows the air discharged by the blower 20 to be discharged from the air outlet 51a along the first direction a, thus facilitating efficient air discharge from the blower 20.

[0101] like Figure 1 and Figure 4 As shown in this embodiment, the impeller includes a rotating component 21, a baffle plate 23, and multiple blades 22. The rotating component 21 is connected to a motor 30, and the multiple blades 22 are connected around the periphery of the rotating component 21. The rotating component 21 and the multiple blades 22 are connected to the baffle plate 23. An air inlet is provided on the periphery of the multiple blades 22, and an air outlet is provided on the side of the multiple blades 22 facing away from the baffle plate 23. The rotating component 21 is driven to rotate by the motor 30, thereby causing the multiple blades 22 to rotate around the rotating component 21. Through the rotation of the multiple blades 22, the air around the multiple blades 22 is guided to the air outlet. The airflow flows from the side of the impeller to the axial direction, thereby realizing the air outlet of the blower 20. In this embodiment, the baffle plate 23 is arranged facing the air inlet 40a, which can prevent external dust from directly entering the blower 20 and other structures, so as to ensure that the air pump can work stably. Of course, in other embodiments, the baffle plate 23 may not be provided. In this case, the side of the multiple blades 22 facing the air inlet 40a is the air inlet, and the airflow flows directly along the axial direction of the impeller to realize the air outlet of the blower 20.

[0102] like Figure 1 and Figure 4 As shown in the embodiment of this application, the blower through-hole 60b is inclined along the first direction a towards the rotation direction of the plurality of blades 22. It should be noted that when the plurality of blades 22 rotate to discharge air, the discharged airflow is not arranged along the axial direction of the impeller, but rather at a certain angle to the circumferential direction of the impeller. The inclined arrangement of the blower through-hole 60b allows it to adapt to the airflow of the blower device 20, enabling the blower device 20 to efficiently discharge a large amount of air, thereby improving the blowing efficiency of the blower device 20.

[0103] For example, the air duct component 60 is provided with a plurality of air through holes 60b, and adjacent air through holes 60b are provided with inclined baffles to form the aforementioned inclined air through holes 60b.

[0104] like Figure 1As shown in the embodiment of this application, the air pump also includes an air outlet pipe 54. The air pump 10 includes a piston assembly 11 and a piston pipe 12. The piston assembly 11 is connected to the piston pipe 12, and the piston pipe 12 is connected to the air outlet 52a through the air outlet pipe 54. The piston assembly 11 is provided with a retractable piston, which is located in the piston pipe 12. The motor 30 is connected to the piston assembly 11 to drive the piston to reciprocate within the piston pipe 12. It can be understood that the air pump 10 is a piston pump. One side of the piston assembly 11 is the air inlet. The motor 30 drives the piston to reciprocate within the piston pipe 12. Specifically, the motor 30 can drive the transmission component of the piston assembly 11 to rotate, thereby causing one end of the piston to swing. When one end of the piston swings, the other end can reciprocate within the piston pipe 12 to repeatedly pressurize the gas into the piston pipe 12, thereby discharging the high-pressure gas from the air outlet pipe 54 and the air outlet 52a to output high-pressure air. Of course, in other embodiments, the air pump 10 may also be a diaphragm pump.

[0105] For example, the end of the piston pipe 12 is sleeved on the inner wall of the air outlet pipe 54. In this way, the piston pipe 12 can be stably connected to the air outlet 52a through the air outlet pipe 54, facilitating stable air output. In this application, the air pump 10 can be selectively installed at different positions along the first direction a of the housing 40 as needed. Thus, by simply replacing the air outlet pipe 54 with one of different lengths, the air pump 10 and the air outlet 52a can be connected to ensure stable air output.

[0106] like Figure 1 and Figure 2 As shown in the embodiment of this application, the piston assembly 11, piston pipe 12, and air outlet pipe 54 are arranged sequentially along the first direction a. This arrangement allows the air pump 10 to better fit the shape of the housing 40, so that it can be more compactly installed inside the housing 40, which is beneficial to the structural integration inside the housing 40, and further makes the air pump device miniaturized, so as to facilitate its portability and use.

[0107] like Figure 1 and Figure 2 As shown in the embodiment of this application, both the piston pipe 12 and the air outlet pipe 54 extend along the first direction a. This arrangement, on the one hand, allows parts of the air pump 10 and its connected structures to better fit the shape of the housing 40, resulting in a more compact structure within the housing 40 and facilitating structural integration within the housing 40. On the other hand, when the air pump 10 discharges air, it also discharges air along the first direction a. Combined with the above embodiment, the air outlet direction of the blower 20 is along the first direction a. This makes the air discharge and airflow of the air pump / blower device more smooth and prevents mutual interference, thus facilitating its use.

[0108] like Figure 1 and Figure 5 As shown in the embodiment of this application, an air nozzle structure 50 is also provided. The air nozzle structure 50 includes the first interface 51 and the second interface 52 mentioned above, and the second interface 52 is disposed within the first interface 51.

[0109] It should be noted that since the air pump 10 outputs high-pressure gas, when the high-pressure gas is released through the air outlet 52a, it will generate high temperature at the second interface 52, which can easily burn the human body.

[0110] The nozzle structure 50 of this embodiment can inflate the device to be inflated and the blower to be blown. When inflating the device to be inflated through the second interface 52 and the air pump 10, the second interface 52 is located inside the first interface 51, preventing the user from directly contacting the second interface 52 and being burned. Furthermore, the user can simultaneously turn on the blower 20 as needed, allowing air from the blower 20 to pass through the air outlet 51a. Since the second interface 52 is located inside the first interface 51, the air passing through the air outlet 51a can dissipate heat and cool the second interface 52, preventing burns even if the user accidentally touches it, thus improving the user experience. It should be noted that when inflating the device to be inflated, the user can also choose not to turn on the blower 20, but only turn on the air pump 10 to inflate the device through the air outlet 52a.

[0111] In addition, this embodiment of the application can also receive the blower through the second interface 52 and blow air onto the blower through the blower device 20. Since the second interface 52 is located inside the first interface 51, the user can simultaneously turn on the air pump 10 as needed, so that the gas discharged by the air pump 10 overlaps with the gas discharged by the blower device 20, thereby increasing the air volume and blowing pressure of the blower device 20 and improving the blowing efficiency. It should be noted that when blowing air onto the blower, the user can also choose not to turn on the air pump 10, but only turn on the blower device 20 to blow air onto the blower through the air outlet 51a.

[0112] like Figure 1 and Figure 5As shown in this embodiment, the air nozzle structure 50 further includes an air outlet pipe 54. One end of the air outlet pipe 54 is connected to an air outlet hole 52a. An air outlet channel is formed between the inner wall of the air outlet pipe 54 and the air outlet hole 52a, which is used to supply air to the air pump 10. The other end of the air outlet pipe 54 can be connected to the air pump 10. The gas discharged by the air pump 10 will pass through the air outlet channel and enter the device to be inflated. The specific connection method between the air outlet pipe 54 and the air pump 10 can be referred to the above. In this embodiment, since the air outlet pipe 54 is connected to the air outlet hole 52a, when the air pump 10 inflates the device to be inflated, the high-pressure gas is discharged through the air outlet channel. In this way, the high-pressure gas will be discharged from the air outlet pipe 54 or the air outlet hole 52a, reducing the heat directly generated on the second interface 52. Therefore, the temperature of the second interface 52 can be reduced to a certain extent, avoiding burns to the user.

[0113] For example, one end of the vent pipe 54 is flush with the outer surface of the second interface 52. In this way, the second interface 52 is actually sleeved on the end of the vent pipe 54. The high-pressure gas is actually released from the end of the vent pipe 54, which reduces the heat generated on the second interface 52. Therefore, the temperature of the second interface 52 can be reduced to a certain extent to avoid scalding the user.

[0114] For example, the vent pipe 54 has a stepped protrusion on its periphery. When one end of the vent pipe 54 is connected to the vent hole 52a, one end of the vent pipe 54 is adapted to and embedded in the vent hole 52a, and the stepped protrusion abuts against the side of the second interface 52 facing the housing 40. In this way, a stable connection between the vent pipe 54 and the vent hole 52a is achieved.

[0115] like Figure 6 As shown in this embodiment, the outer casing 40 is further provided with a fixing component 53. One end of the fixing component 53 surrounds and wraps around the second interface 52, and the other end of the fixing component 53 is connected to the inner wall of the first interface 51. The fixing component 53 securely connects the first interface 51 and the second interface 52, ensuring stable support for the second interface 52, which in turn allows for stable connection to the air pump 10 for air output. Of course, in other embodiments, the other end of the fixing component 53 can be fixedly connected to the outer casing 40 to stably support the second interface 52.

[0116] like Figure 6As shown in this embodiment, multiple air outlets 51a are provided, and these multiple air outlets 51a are spaced apart from the air outlets 52a. The multiple air outlets 51a increase the airflow, thereby achieving a better blowing effect for the blower device 20. Furthermore, the multiple air outlets 51a are spaced apart from the air outlets 52a, allowing the air blower to operate independently when discharging air and air, facilitating its use. Of course, in other embodiments, the multiple air outlets 51a can be connected into one, with airflow achieved through a single large air outlet.

[0117] For example, the space between the second interface 52 and the first interface 51 is divided into multiple air outlets 51a by the fixing component 53, so that the second interface 52 is supported and air can be discharged through the air outlets 51a.

[0118] like Figure 6 As shown in the embodiment of this application, multiple air outlets 51a are arranged in a circle around the air outlet 52a. In this way, when air is expelled through the blower 20, all the air outlets 51a can dissipate heat and cool the second interface 52, preventing burns even if the user accidentally touches the second interface 52, thus improving the user experience. Furthermore, this arrangement allows the air pump to maintain a balanced and stable airflow and / or air volume.

[0119] like Figure 6 As shown, exemplarily, the fixing component 53 includes a plurality of connectors 531 arranged at intervals around the second interface 52. The two ends of each connector 531 are respectively connected to the inner wall of the first interface 51 and the outer wall of the second interface 52. The plurality of surrounding air outlets 51a can be formed by the inner wall of the first interface 51, the plurality of connectors 531, and the outer wall of the second interface 52. Furthermore, the connectors 531 are wider at both ends and narrower in the middle. This ensures stable and reliable support for the second interface 52 and maximizes the size of the air outlets 51a, ensuring a larger airflow. Furthermore, the plurality of connectors 531 are evenly spaced around the second interface 52. For example, the fixing component 53 includes three connectors 531 evenly spaced around the second interface 52.

[0120] like Figure 1 and Figure 6 As shown in the embodiment of this application, an air outlet channel is formed between the outer shell 40, the fixing component 53, the air outlet 51a, and the outer wall of the air outlet pipe 54. The air outlet channel is used to supply air to the blower 20. In this way, the air outlet channel and the air outlet channel are independent of each other and do not affect each other, which can ensure better air outlet and air outlet effects, so as to facilitate the use of the air pumping device.

[0121] For example, the air outlet channel is connected to the aforementioned blower channel 40b, and the air discharged by the blower device 20 passes through the blower channel 40b and the air outlet channel to achieve air outlet.

[0122] like Figure 6 As shown in the embodiment of this application, the first interface 51 has a first end that is away from the air pump, and the second interface 52 has a second end that is away from the air pump. The second end is located on the side of the first end facing the outer casing 40. It can be understood that the second interface 52 is located inside the first interface 51 facing the air pump. In this way, it can further prevent the user from directly contacting the second interface 52 and being burned by the second interface 52.

[0123] like Figure 6 As shown in the embodiment of this application, the first interface 51 protrudes from the surface of the housing 40. This facilitates the connection between the first interface 51 and the blower, and also enables the second interface to be located inside the first interface 51 facing the blower.

[0124] like Figure 6 As shown in the embodiment of this application, the first interface 51, the second interface 52 and the fixing member are all integrally formed on the outer shell 40. That is to say, when making the outer shell 40, part of the structure of the air nozzle structure 50 can be directly formed by injection molding, thereby improving the structural strength of the air nozzle structure 50.

[0125] like Figure 6 As shown in the embodiment of this application, both the first interface 51 and the second interface 52 are circular interfaces to facilitate connection with the device to be blown and the device to be inflated.

[0126] like Figure 7 As shown in the embodiment of this application, the nozzle structure 50 further includes a fixing member, which is disposed on the first interface 51 or the second interface 52. The fixing member is used to fix the nozzle structure 50 to the blowing device or the inflation device. The fixing member fixes the nozzle structure 50 to the blowing device or the inflation device to the inflation device.

[0127] like Figure 7 As shown in the embodiment of this application, the fixing member includes a first fixing member 71, which is arranged around the outside of the first interface 51, and is used to guide the air outlet of the blower 20 to the device to be blown. This facilitates blowing air onto the device to be blown. It should be noted that when blowing air onto the device to be blown, the blower 20 and the air pump 10 can be turned on simultaneously to blow air onto the device to be blown, thereby increasing the air volume, or the blower 20 can be turned on alone to blow air onto the device to be blown.

[0128] like Figure 7As shown, exemplarily, the outer side of the first interface 51 is provided with a protrusion, and the inner wall of the interface of the first fixing member 71 connecting to the first interface 51 is provided with an L-shaped snap-fit ​​groove. One end of the L-shaped snap-fit ​​groove is connected to the outside of the interface of the first fixing member 71. When connecting the first fixing member 71, the user can fit the interface of the first fixing member 71 onto the outside of the first interface 51, so that the protrusion is placed in the L-shaped snap-fit ​​groove. Then, by rotating the interface of the first fixing member 71, the protrusion is locked into the L-shaped snap-fit ​​groove, and the interface of the first fixing member 71 is not easily disengaged along the axial direction of the first interface 51, so as to achieve a stable connection between the first fixing member 71 and the first interface 51. This ensures that the air pump can achieve stable air blowing through the first fixing member 71. Of course, in other embodiments, the interface of the first fixing member 71 and the first interface 51 can also be connected by other snap-fit ​​methods, or by magnetic attraction or thread, without limitation.

[0129] like Figure 7 As shown, for example, the first fixing member 71 is horn-shaped. Specifically, the end of the first fixing member 71 with a larger circumference is fixed to the air nozzle interface, and the end of the first fixing member 71 with a smaller circumference extends outward to facilitate airflow and increase the airflow velocity into the air-blowing device to improve the blowing efficiency of the air-blowing device.

[0130] In this embodiment, the fixing member further includes a second fixing member, which is arranged around the air outlet 52a and the air outlet 51a to guide the air output from the air pump 10 to the device to be inflated. This facilitates the inflation of the device. It should be noted that when inflating the device, both the blower 20 and the air pump 10 can be turned on simultaneously to dissipate heat from the second interface 52 while inflating, or the air pump 10 can be turned on alone to inflate the device.

[0131] For example, the inner wall of the second interface 52 or the inner wall of the air outlet pipe 54 is provided with internal threads, and the interface end of the second fixing member is provided with external threads. The second fixing member and the air nozzle structure 50 are connected by threads to achieve a stable connection between the second fixing member and the air nozzle structure 50. This ensures that the air pump can achieve stable inflation through the second fixing member. Of course, in other embodiments, the interface of the second fixing member and the second interface 52 can also be connected by a snap-fit ​​method or a magnetic method, without limitation.

[0132] For example, the second fixing member is horn-shaped. Specifically, the end of the second fixing member with a larger circumference is fixed to the air nozzle structure 50, and the end of the second fixing member with a smaller circumference extends outward to facilitate air guidance and increase the air flow rate into the device to be inflated, thereby improving the inflation efficiency of the air blower.

[0133] In the air-blowing device of this application, the fixing component is snap-fitted or threadedly connected to the device to be blown or inflated. This ensures a secure connection between the fixing component and the device to be blown or inflated, thereby achieving stable blowing and inflation.

[0134] like Figure 1 and Figure 2 As shown in the embodiment of this application, the air pump also includes a switch (not shown), which is located on the housing 40. The switch is used to control the air pump to enter either an air pumping mode, a blower mode, or an air pumping and blower mode. Through the switch, the user can select the operating mode of the air pump to improve the user experience. In the inflation mode, the motor 30 drives only the air pump 10 without driving the blower 20, and the air pump and blower can be used to inflate the device to be inflated; in the blower mode, the motor 30 drives only the blower 20, while the air pump 10 does not operate, and the air pump and blower can be used to blow air onto the device to be inflated; in the air pump and blower mode, the motor 30 drives both the air pump 10 and the blower 20 simultaneously, and the air pump and blower can be used to blow air onto the device to be inflated, while the air pump 10 increases the air volume. Alternatively, the air pump and blower can also be used to inflate the device to be inflated, inflating it through the air pump 10, while the blower 20 cools the nozzle structure 50 through the air outlet.

[0135] like Figure 1 and Figure 2 As shown in the embodiment of this application, the air pump also includes an energy storage module (not shown) and an emergency start-up power output interface (not shown). The energy storage module is located inside the housing 40, and the emergency start-up power output interface is electrically connected to the energy storage module. The energy storage module can store electrical energy, and when needed, it can provide emergency power to the vehicle through the emergency power output interface, for example, for emergency vehicle starting. This makes the air pump more portable and easier to use. It should be noted that the energy storage module of this application can also be used to power the motor 30, enabling the motor 30 to perform corresponding operations.

[0136] like Figure 1 and Figure 2 As shown in the embodiments of this application, the air compressor / blower also includes one or more of the following: a USB interface, an AC socket, a DC interface, and a cigarette lighter socket. The USB interface, AC socket, DC interface, emergency start-up power output interface, and cigarette lighter socket are electrically connected to the energy storage module. Power can be supplied to other electronic devices through various electrical connection interfaces. The type of electrical connection interface can be varied depending on the different electronic devices to achieve multi-functional power supply.

[0137] The aforementioned electrical connection interfaces can be located on the housing 40 for easy connection and use.

[0138] like Figure 1 and Figure 2 As shown in the embodiment of this application, the air pump also includes an inverter module (not shown). The energy storage module is connected to the electrical connection interface of the energy storage device through the inverter module to provide AC power to the electrical connection interface.

[0139] like Figure 1 and Figure 2 As shown in the embodiment of this application, the air blower also includes a charging interface (not shown). The charging interface is electrically connected to the energy storage module and is located on the outer casing 40. The charging interface is used to charge the energy storage module so as to charge the energy storage module for convenient use of the air blower.

[0140] like Figure 1 and Figure 2 As shown in the embodiment of this application, the air pumping device is also equipped with a main control board (not shown in the figure). The main control board is connected to various electrical connection interfaces, charging interfaces, energy storage modules, switches, motors 30 and other electrical components to realize the corresponding control requirements.

[0141] like Figure 1 and Figure 2 As shown in the embodiment of this application, the outer casing 40 includes a first casing 41 and a second casing 42. Both the first casing 41 and the second casing 42 extend along a first direction a. The first casing 41 is provided with a mounting groove 41a, and the aforementioned air nozzle structure 50 and air inlet 40a are both provided on the first casing 41. When installing the blower 20, the motor 30, and the air pump 10, the air pump 10 and the motor 30 can be fixed to the bottom of the mounting groove 41a with screws. The air duct component 60 is installed at the end of the motor 30 near the air inlet 40a, and the mounting hole 60a of the air duct component 60 is nested in the end of the motor 30. The motor 30 is connected to the blower 20 through a second output shaft and supports the blower 20. The second casing 42 covers the opening of the mounting groove 41a and is connected to the first casing 41, so that the blower 20, the motor 30, and the air pump 10 are placed inside the outer casing 40.

[0142] like Figure 1 and Figure 2 As shown in the embodiment of this application, the main control board, energy storage module, etc. are installed inside the housing 40 and can be located at the blower channel 40b. In this way, when the air is blown out through the blower device 20, the main control board, energy storage module, etc. can also be cooled down to ensure the stable operation of the air blowing device.

[0143] For example, the main control board, energy storage module, etc., can be installed on the side of the motor 30 and / or air pump 10 away from the bottom of the mounting slot 41a, and located on the side of the air duct component 60 away from the blower 20, so as to ensure stable air output from the blower 20 and securely install the main control board, energy storage module, etc. At the same time, this arrangement can make full use of the redundant space inside the housing 40, eliminating the need for additional space for installation, making the internal structure of the air pump more compact and facilitating its portability and use.

[0144] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the content of this application's specification and drawings under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
