Description

Air pump blower Technical Field

[0001] This invention relates to the field of inflation technology, and more particularly to an integrated air inflator and blower. Background Technology

[0002] An air pump is an inflation tool widely used in inflation services for inflatable equipment such as tires, balloons, and air mattresses. It inflates by drawing in outside air and expelling it into the equipment. To add a blower function, an additional blower device is often included within the air pump. However, these air pumps with built-in blowers are relatively large and inconvenient to carry.

[0003] Application content

[0004] The purpose of this invention is to provide an integrated air pump and blower, which aims to solve the technical problem of the large size of air pumps with blower devices.

[0005] To achieve the above objectives, the present invention provides an integrated air pump and blower as defined in the claims.

[0006] The air pump and blower provided by this invention are driven by the same motor when inflating and / or blowing air. Therefore, compared with the prior art, the space occupied by the additional motor can be reduced, thereby reducing the size of the outer shell and thus reducing the volume and weight of the air pump and blower, which is convenient for carrying and use.

[0022] As shown in Figures 1 and 2, the air pump and blower integrated machine provided in this embodiment of the invention includes an air pump 10, a blower device 20, a motor 30, and a housing 40, such as an outer shell 40.

[0023] The motor 30 is connected to the blower 20 and the air pump 10 to drive the blower 20 and / or the air pump 10.

[0024] The air pump 10, the blower 20, and the motor 30 are all housed inside the outer casing 40.

[0025] In a preferred embodiment, the blower 20, the motor 30, and the air pump 10 are arranged sequentially along a first direction of the housing 40 (e.g., the length or width direction of the housing; Figure 2 shows the length direction).

[0026] An air inlet 40a is provided on the outer casing 40. A blower 20 (e.g., an impeller 20, as shown in Figure 4) is disposed adjacent to the air inlet 40a. Airflow enters the blower 20 from the air inlet 40a on the outer casing and then enters the blower passage 40b. The blower passage 40b is used to guide the flow of the blower airflow within the casing 40. The blower passage 40b is connected to the blower 20 and also to the air outlet 50.

[0027] Preferably, a portion of the blower channel 40b is located between the air pump 10 and the housing 40; more preferably, the space between the air pump 10 and the housing 40 forms a portion of the blower channel 40b.

[0028] Moreover, preferably, a portion of the blower channel 40b is located between the motor 30 and the housing 40, and more preferably, the space between the motor 30 and the housing 40 forms a portion of the blower channel 40b.

[0029] The outer casing 40 is provided with a first interface 51 and a second interface 52. The first interface 51 is used to receive an external blower, and the second interface 52 is used to receive an external inflation device. The first interface 51 includes an air outlet 51a, and the second interface 52 includes an air outlet 52a. The first interface 51 / air outlet 51a is connected to the blower 20 to supply air to the blower 20, and the second interface 52 / air outlet 52a is connected to the air pump 10 to supply air to the air pump 10.

[0030] In a preferred embodiment, the second interface 52 is disposed within the first interface 51. For example, the interface formed at the connection between the first interface 51 and the housing 40 completely covers the interface formed at the connection between the second interface 52 and the housing 40. More preferably, the second interface 52 and the first interface 51 are coaxially arranged, for example, the second interface 52 and the first interface 51 form an inner and an outer concentric ring / circle.

[0031] In another embodiment, the first interface 51 and the second interface 52 can be two interfaces that do not overlap with each other, that is, two independent interfaces.

[0032] 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. The present invention can select to use either the air pump 10 or the blower device 20, or use both the air pump 10 and the blower device 20 simultaneously, depending on the usage scenario.

[0033] It should be noted that the present invention preferably uses the same motor 30 to drive the blower 20 and the air pump 10. For example, the present invention preferably uses only one motor 30 to drive the air pump 10 and the blower 20.

[0034] The motor 30 is driven to the blower 20, and the motor 30 is driven to the air pump 10.

[0035] For example, as shown in Figure 8, one output end (output shaft) 302 of the motor 30 is connected to the blower 20, for example, to the impeller of the blower 20, driving the impeller to rotate; the other output end (output shaft) 301 of the motor 30 is connected to the air pump 10, for example, to the piston assembly 11 of the air pump. For example, the output end 301 of the motor has a gear assembly, and the piston assembly 11 of the air pump also has a gear assembly. Through the meshing of the gear assemblies, the motor drives the piston assembly 11 and drives the piston rod to move.

[0036] Preferably, the output shaft 302 of the motor 30 connected to the blower 20 and the output shaft 301 of the motor 30 connected to the air pump 10 are collinear (located on the same line), or even coaxial (belonging to the same output shaft). For example, the output shaft 302 and the output shaft 301 are outputs from the same rotating shaft within the motor 30.

[0037] In the embodiment shown in Figure 8, the motor 30 is connected to the blower 20 and the air pump 10 via the output terminals 302 and 301 located on the left and right sides, respectively.

[0038] In another embodiment, the motor 30 can also be sequentially connected to the blower 20 and the air pump 10 via the output terminal on the same side (e.g., the output terminal 301 on the left side). For example, the output terminal 301 of the motor 30, along the axial direction, is first connected to the blower 20 (e.g., the impeller of the blower 20 is fixedly connected to the output terminal 301 by a fastener), and then connected to the air pump 10 (e.g., the air pump 10 is connected to the output terminal 301 by a gear assembly).

[0039] The motor 30 of the present invention can simultaneously drive the air pump 10 and the blower 20.

[0040] In a preferred embodiment, when the motor 30 is running, both the air pump 10 and the blower 20 are running simultaneously. When the motor 30 stops, both the air pump 10 and the blower 20 stop.

[0041] In another embodiment, the motor 30 of the present invention can also drive the air pump and the blower 20 to operate separately. That is, the motor 30 can be configured to drive the air pump 10 to operate alone in the air pumping mode, while the blower 20 does not operate, and / or the motor 30 can also be configured to drive the blower 20 to operate alone in the blower mode, while the air pump 10 does not operate.

[0042] It should be noted that the first interface 51 and the second interface 52 of the present invention can be a combined interface, or the first interface 51 and the second interface 52 can be independent interfaces.

[0043] This embodiment of an air pump and blower unit allows the air pump 10 to inflate the device through the second interface 52, and the blower 20 to blow air onto the device through the first interface 51. Furthermore, both the air pump 10 and the blower 20 are driven by the same motor 30 during inflation and / or blowing. Therefore, compared to existing technologies, 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 unit, making it easier to carry and use. For example, in practical applications, the air pump and blower unit can be used as an emergency device in a car, and therefore is typically kept in the car for extended periods. Reducing the size and weight of the air pump and blower unit makes it more convenient for carrying and emergency use in a car.

[0044] As shown in Figures 1 and 2, in this embodiment of the invention, the blower 20 and the air pump 10 are sequentially arranged along a first direction a. Preferably, the first direction a is the extension direction of the length of the outer casing 40, i.e., the longitudinal direction of the outer casing 40. This arrangement allows the blower 20 and the air pump 10 to be more compactly housed within the outer casing 40, which is beneficial for structural integration within the outer casing 40 and further miniaturizes the integrated air blower and air pump, making it easier to carry and use.

[0045] As shown in Figures 1 and 2, in this embodiment of the invention, the outer casing 40 has an air outlet 50 at its end along the first direction a, which includes a first interface 51. 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 50 through the blower channel 40b, for example, to the air outlet 51a. It is 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 and blower unit. 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.

[0046] For example, the space between the air pump 10 body and the inner wall of the housing 40 forms at least a partial blower channel 40b. This simplifies the construction of the integrated air pump and blower, reduces its weight for easier portability, and ensures that when the blower 20 discharges air along the blower channel 40b, the airflow in the blower channel 40b provides sufficient and stable ambient airflow for the air pump 10. When the air pump 10 is operating, the airflow in the blower channel 40b, as ambient gas, can directly enter the air pump 10; therefore, this arrangement also benefits the airflow and discharge of the air pump 10.

[0047] As shown in Figures 1 and 2, in this embodiment of the invention, one end of the outer casing 40 is provided with an air inlet 40a, for example, an air inlet 40a is provided at the beginning along the first direction a. It should be noted that since the blower device 20 and the air pump 10 are arranged sequentially along the first direction a, the air inlet of the blower device 20 is close to the air inlet 40a. This facilitates the introduction of outside air into the air pump and blower unit via the blower device 20. Combined with the aforementioned first interface 51 being located at the end of the outer casing 40 along the first direction a, the air inlet and outlet of the blower device 20 are arranged along the length of the outer casing 40. Under the guidance of the blower device 20, the air can flow rapidly along the first direction a. This further facilitates the air outlet of the blower device 20, enabling it to provide a large amount of gas to the equipment being blown.

[0048] As shown in Figures 1 and 2, in this embodiment of the invention, 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 the gas entering the blower channel 40b can be considered ambient gas. It enters from the air inlet of the air pump 10, and 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 invention, the blower device 20 can guide and accelerate the entry of outside air into the blower channel 40b, providing a stable and sufficient ambient gas for the air pump 10 to improve inflation efficiency. Of course, when the blower device 20 is not working, outside gas can also pass through the blower device 20 and enter the blower channel 40b to enter the air pump 10, enabling the air pump 10 to inflate. In addition, both the first interface 51 and the second interface 52 are located at the end of the outer casing 40, which allows the user to easily connect the device to be inflated and / or the device to be blown, for convenient use.

[0049] As shown in Figures 1 and 2, in this embodiment of the invention, 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 integrated air pump and blower more compact and rational in structure. Furthermore, placing the motor 30 between the air pump 10 and the blower 20 allows the blower 20 to be closer to the air inlet 40a, facilitating the blower 20 in guiding outside air into the integrated air pump and blower. 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 integrated air pump and blower for easier carrying and use. Of course, in other embodiments, the motor 30 can also be located on the side of the blower 20 away from the air pump 10. That is, the motor 30, the blower 20, and the air pump 10 are arranged sequentially along the first direction a.

[0050] As shown in Figures 1 and 2, in this embodiment of the invention, one end of the motor 30 is provided with a first output shaft 301, and the other end of the motor 30 is provided with a second output shaft 302. 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.

[0051] In some embodiments, a clutch is provided between the first output shaft of the motor 30 and the first drive shaft of the air pump 10, and / or, a clutch 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 engage the clutch 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 independently; or individually engage the clutch between the second output shaft of the motor 30 and the second drive shaft of the blower 20 to drive the blower 20 independently; or simultaneously engage the clutches at both ends of the motor 30 to allow the motor 30 to simultaneously drive both the air pump 10 and the blower 20.

[0052] In some embodiments, a clutch 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 engage the clutch 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 both the air pump 10 and the blower 20; alternatively, the clutch can be left undisturbed to drive the blower 20 alone.

[0053] 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 is provided between the second output shaft of the motor 30 and the second drive shaft of the blower 20. Thus, the user can engage the clutch 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 can be left undisturbed to drive the air pump 10 alone.

[0054] For example, the clutch 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 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 clutch is not energized, the input end and the output end are disconnected, and torque cannot be transmitted. When the 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 can also be other types of clutches, which will not be elaborated here.

[0055] As shown in Figures 1 to 3, in this embodiment of the invention, the air compressor and blower also includes an air duct component 60.

[0056] The air duct component 60 is located in the air outlet direction of the blower 20. The air duct component 60 facilitates the guidance of airflow from the blower 20 into the blower channel 40b. For a more compact structure, the air duct component 60 is preferably installed around at least a portion of the motor 30 (or air pump 10).

[0057] For example, the air duct component 60 has a mounting hole 60a, where at least one of the blower 20, motor 30, and air pump 10 is fixed. On one hand, the air duct component 60 securely mounts at least one of the blower 20, motor 30, and air pump 10. On the other hand, the air duct component 60 can serve as an internal air guide structure for the integrated blower and air pump, directing the airflow from the blower 20 into the blower channel 40b to facilitate the air output from the blower 20 and the air output from the air pump 10. It should be noted that the air duct component 60 can be used alone to fix one of the blower 20, motor 30, and air pump 10, or it can fix two or more of these components simultaneously, as long as the air duct component 60 ensures smooth air output from the blower 20 and the air output from the air pump 10.

[0058] As shown in Figures 2 and 3, exemplarily, the periphery of the air duct component 60 is adapted to and snapped into the inner wall of the housing 40, thereby securely installing the air duct component 60 to provide stable support for at least one of the installed blower 20, motor 30, and air pump 10. In another embodiment, the air duct component 60 and the housing 40 can be integrally formed.

[0059] As shown in Figures 1 to 3, 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 integrated blower and air pump.

[0060] As shown in Figures 2 and 3, exemplarily, the motor 30 is secured to the mounting hole 60a of the air duct component 60. When the motor 30 is located between the blower 20 and the air pump 10, the motor 30 can be securely 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 installation of the motor 30.

[0061] As shown in Figures 1 to 3, in this embodiment of the invention, the integrated air compressor and blower further includes an air duct component 60. The air duct component 60 has an air through hole 60b, and the blower device 20 has an air outlet. The air outlet is connected to the air outlet 51a through the air through hole 60b. The air duct component 60 can guide the air out of the blower device 20, thereby facilitating air output from the blower and improving blower efficiency.

[0062] As shown in Figures 2 and 3, 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 blower unit and guide the airflow from the blower device 20, improving blower efficiency.

[0063] As shown in Figures 1 and 2, in this embodiment of the invention, 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. As shown in Figure 2, when the blower 20 is running, the air it discharges passes through the blower through-hole 60b, the blower channel 40b, and the air outlet 51a, realizing the air outlet of the blower 20.

[0064] As shown in Figures 1 and 4, in this embodiment of the invention, the blower 20 includes an impeller, and a motor 30 is connected to the impeller to drive the impeller to rotate. The rotation of the impeller guides the air from the inlet of the blower 20 to the outlet, thus achieving air output.

[0065] As shown in Figures 1 and 4, in this embodiment of the invention, the drive axis (rotation axis) 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 airflow from the blower 20.

[0066] As shown in Figures 1 and 4, in this embodiment of the invention, the impeller includes a rotating component 21 and a plurality of blades 22. The rotating component 21 is connected to the motor 30, and the plurality of blades 22 are connected around the periphery of the rotating component 21.

[0067] Preferably, the impeller also has a baffle plate 23. Preferably, the baffle plate 23 is located on a plane perpendicular to the rotation axis of the impeller (first direction a). The baffle plate 23 is disposed on the side near the air inlet 40a. The baffle plate 23 is used to block the airflow from flowing towards the air inlet, thereby causing the airflow to flow towards the air outlet. In addition, since the blades 22 of the blower 20 are often relatively large, the baffle plate 23 can also play a fixing and reinforcing role, preventing the blades 22 from breaking during rotation.

[0068] The rotating component 21 and multiple blades 22 are connected to the baffle plate 23. The multiple blades 22 have air inlets on their periphery and air outlets on the side of the multiple blades 22 away from the baffle plate 23. The rotating component 21 is driven to rotate by the motor 30, which in turn drives 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, so as to realize the air outlet of the blower 20.

[0069] In one embodiment, the plane / arc surface where the blade 22 is located is perpendicular to the baffle 23; in other words, the plane / arc surface where the blade 22 is located is parallel to the rotation axis (first direction a) of the impeller 22. In another embodiment, to enhance the direction of airflow, the plane / arc surface where the blade 22 is located may not be perpendicular to the baffle 23; in other words, the plane / arc surface where the blade 22 is located is not parallel to the rotation axis (first direction a) of the impeller 22, but forms a certain angle of inclination.

[0070] In this embodiment, the baffle 23 is positioned facing the air inlet 40a to prevent external dust from directly entering the blower 20 and other structures, thus ensuring the stable operation of the integrated air pump and blower. Of course, in other embodiments, the baffle 23 may be omitted. In this case, the side of the multiple blades 22 facing the air inlet 40a becomes the air intake, and the airflow flows directly along the impeller's axial direction to achieve air outlet for the blower 20. Especially when the plane / arc surface of the blades 22 is not parallel to the rotation axis (first direction a) of the impeller 22, forming a certain tilt angle, airflow can still be directed towards the outlet direction even without the baffle.

[0071] As shown in Figure 3b, the air duct component 60 of the present invention has an inner wall 601, an outer wall 602, and a plurality of partitions 603 located between the inner wall 601 and the outer wall 602.

[0072] The outer wall 602 can be a ring (or part of a ring); the inner wall 601 can be a ring (or part of a ring).

[0073] The inner wall 601 forms a mounting hole 60a. This hole can be used to mount at least a portion of the motor 30 or the air pump 10, resulting in a more compact structure.

[0074] A notch 60c can also be formed on the outer wall 602 and the inner wall 601. For example, it can be used for wiring of the motor 30.

[0075] A plurality of baffles 603 are provided between the inner wall 601 and the outer wall 602. Preferably, the plane / arc surface where the baffles 603 are located is not parallel to the rotation axis (first direction a) of the impeller 22, but forms a certain inclination angle (as shown in Figure 3b), thereby forming a guide air duct 60b from the air inlet direction to the air outlet direction (from the air inlet 40 to the blower channel 40b).

[0076] As shown in Figures 1 and 4, in this embodiment of the invention, the blower through-hole (guide duct) 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, thus improving the blowing efficiency of the blower device 20.

[0077] 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 partitions 603 to form the aforementioned inclined air through holes 60b.

[0078] As shown in Figure 1, in this embodiment of the invention, the air pump and blower also includes an air outlet pipe 54 for air outlet of the air pump 10.

[0079] The air pump 10 includes a piston assembly 11 and a piston conduit 12. The piston assembly 11 is connected to the piston conduit 12, and the piston conduit 12 is connected to an air outlet 52a via an air outlet pipe 54. The piston assembly 11 has a retractable piston located in the piston conduit 12. A motor 30 is connected to the piston assembly 11 to drive the piston to reciprocate within the piston conduit 12. For example, the motor 30 drives the piston assembly 11 via gear engagement, and the piston assembly 11 is connected to a drive piston rod, which moves within the piston conduit 12.

[0080] In one embodiment, the air pump 10 is a piston pump, with one side of the piston assembly 11 serving as an air inlet. A motor 30 drives the piston to reciprocate within the piston channel 12. For example, the motor 30 can drive the transmission component of the piston assembly 11 to rotate, thereby causing one end of the piston to oscillate. While one end of the piston oscillates, the other end reciprocates within the piston channel 12, repeatedly forcing gas into the piston channel 12. This allows high-pressure gas to be discharged from the outlet pipe 54 and the outlet port 52a, thus outputting high-pressure air. Of course, in other embodiments, the air pump 10 can also be a diaphragm pump.

[0081] For example, one 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 invention, 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.

[0082] As shown in Figures 1 and 2, in this embodiment of the invention, 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, enabling it to be more compactly housed within the housing 40. This facilitates structural integration within the housing 40 and further miniaturizes the air pump / blower unit, making it easier to carry and use.

[0083] As shown in Figures 1 and 2, in this embodiment of the invention, 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 outer casing 40, resulting in a more compact structure within the casing 40 and facilitating structural integration. 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 ensures smoother airflow and prevents mutual interference between the air pump and blower, facilitating its use.

[0084] As shown in Figures 1 and 5, in this embodiment of the invention, an air nozzle structure 50 is also provided. The air nozzle structure 50 includes the aforementioned first interface 51 and second interface 52, with the second interface 52 disposed within the first interface 51. The first interface 51 is used to receive an external blower, and the second interface 52 is used to receive an external inflation device.

[0085] 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.

[0086] 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 via 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 select a mode (or in the default mode) to turn on the blower 20 while the air pump 10 is operating, 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.

[0087] In addition, embodiments of the present invention can also receive a blower through the first interface 51 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 select a mode according to needs (or in the default mode) to turn on the air pump 10 while the blower device 20 is working, 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.

[0088] As shown in Figures 1 and 5, in this embodiment of the invention, 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, and an air outlet channel is formed between the inner wall of the air outlet pipe 54 and the air outlet hole 52a. The air outlet channel 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, and 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.

[0089] 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.

[0090] 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.

[0091] As shown in Figure 6, in this embodiment of the invention, 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. Alternatively, 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.

[0092] As shown in Figure 6, in this embodiment of the invention, 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 pump and blower to operate independently during air and air output, facilitating use. Of course, in other embodiments, the multiple air outlets 51a can be connected into one, with air output achieved through a large air outlet.

[0093] 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.

[0094] As shown in Figure 6, in a preferred embodiment of the present invention, multiple air outlets 51a are arranged around an air outlet 52a. For example, the multiple air outlets 51a are arranged around the air outlet 52a as the center. In this way, when air is discharged through the blower 20, the multiple air outlets 51a can all dissipate heat and cool the second interface 52, so even if the user accidentally touches the second interface 52, they can avoid being burned by the second interface 52, thus improving the user experience. In addition, this arrangement allows the air pump and blower to achieve balanced and stable air output and / or airflow.

[0095] As shown in Figure 6, 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 are thus 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.

[0096] As shown in Figures 1 and 6, in this embodiment of the invention, 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 and air output effects, so as to facilitate the use of the air pump blower.

[0097] 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.

[0098] As shown in Figure 6, in this embodiment of the invention, the first interface 51 has a first end that is away from the air compressor / blower, and the second interface 52 has a second end that is away from the air compressor / blower. 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 air compressor / blower from the first interface 51. This further prevents the user from directly contacting the second interface 52 and being burned by it.

[0099] As shown in Figure 6, in this embodiment of the invention, the first interface 51 protrudes from the surface of the outer casing 40. This facilitates the connection between the first interface 51 and the device to be blown, and also allows the second interface to be located inside the air blower unit, with the first interface 51 facing the air blower unit.

[0100] As shown in Figure 6, in this embodiment of the invention, 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.

[0101] As shown in Figure 6, in this embodiment of the invention, 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.

[0102] As shown in Figure 7, in this embodiment of the invention, the nozzle structure 50 further includes a fixing member, which is disposed at 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 secures the nozzle structure 50 to the blowing device, facilitating the blowing of air by the blowing device or the inflation of the inflation device.

[0103] As shown in Figure 7, in this embodiment of the invention, the fixing member may include a first fixing member 71, which is arranged around the outside of the first interface 51, for guiding 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.

[0104] As shown in Figure 7, 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 and blower 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.

[0105] As shown in Figure 7, 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 device to be blown, thereby improving the blowing efficiency of the air pump and blower.

[0106] In another embodiment, the fixing member may include 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.

[0107] 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 and blower 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.

[0108] 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 pump and blower.

[0109] Furthermore, the fasteners of the present invention can be a set of components, such as a set including a first fastener 71 and a second fastener 72. When receiving an external blower, the first fastener 71 is used to connect the air blower of the present invention and the device to be blown. When receiving an external inflation device, the second fastener 72 is used instead to connect the air blower of the present invention and the device to be inflated.

[0110] In the air pump and blower integrated machine of the present invention, the fixing member is snap-fitted or threadedly connected to the device to be blown or inflated. This ensures a secure connection between the fixing member and the device to be blown or inflated, thereby achieving stable blowing and inflation.

[0111] As shown in Figures 1 and 2, in this embodiment of the invention, the air pump and blower also includes a switch (not shown). The switch is located on the outer casing 40 and is used to control the air pump and blower to enter different modes, such as air pumping mode, blower mode, or air pump and blower mode. Through the switch, the user can select the operating mode of the air pump and blower 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 integrated air pump and blower can be used to inflate the equipment 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 integrated air pump and blower can be used to blow air onto the equipment to be inflated. In the inflation and blower mode, the motor 30 drives both the air pump 10 and the blower 20 simultaneously, and the integrated air pump and blower can be used to blow air onto the equipment to be inflated, while the air pump 10 increases the air volume. Alternatively, the integrated air pump and blower can also be used to inflate the equipment to be inflated, with the air pump 10 inflating the equipment, while the blower 20 cools the nozzle structure 50 through the air outlet.

[0112] As shown in Figures 1 and 2, in this embodiment of the invention, the air pump and blower also includes an energy storage module (not shown) and an emergency start-up power output interface (not shown). The energy storage module is housed within the outer casing 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 a vehicle through the emergency power output interface, for example, for emergency vehicle starting. This makes the air pump and blower more portable and easier to use. It should be noted that the energy storage module of this invention can also be used to power the motor 30, enabling the motor 30 to perform corresponding operations.

[0113] As shown in Figures 1 and 2, in this embodiment of the invention, the air pump and 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 these 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.

[0114] The aforementioned electrical connection interfaces can be located on the housing 40 for easy connection and use.

[0115] As shown in Figures 1 and 2, in this embodiment of the invention, the air pump and blower 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.

[0116] As shown in Figures 1 and 2, in this embodiment of the invention, the air pump and 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 pump and blower.

[0117] As shown in Figures 1 and 2, in this embodiment of the invention, the air pump and blower also includes a main control board (not shown). The main control board is connected to various electrical connection interfaces, charging interfaces, energy storage modules, switches, motors 30 and other electrical components to achieve the corresponding control requirements.

[0118] As shown in Figures 1 and 2, in this embodiment of the invention, the outer casing 40 includes a first casing 41 and a second casing 42, both extending along a first direction a. The first casing 41 has a mounting groove 41a, and the aforementioned air nozzle structure 50 and air inlet 40a are both located on the first casing 41. When installing the blower 20, motor 30, and air pump 10, the air pump 10 and 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, motor 30, and air pump 10 are installed inside the outer casing 40.

[0119] As shown in Figures 1 and 2, in this embodiment of the invention, 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 blower.

[0120] 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 and blower more compact and facilitating its portability and use.

[0121] Another embodiment of the present invention is shown in Figures 9a and 9b. The difference between this embodiment and the embodiments shown in Figures 1 and 2 is that the air pump and blower shown in Figures 9a and 9b use an L-shaped air pump. As shown in Figure 9b, the direction a of the drive shaft of the motor 30 driving the air pump (as shown in Figure 8, the direction a of the motor output shaft 301 driving the piston assembly 11) is perpendicular to the movement direction b of the piston rod of the air pump (i.e., the longitudinal direction of the piston pipe 12), i.e., it is L-shaped. This is a characteristic of commercially available L-shaped air pumps.

[0122] In the embodiments shown in Figures 9a and 9b, the blower 20, motor 30, and air pump 10 of the present invention are all housed within the housing 40. The housing 40 has an air inlet 40a. The blower 20 (e.g., an impeller 20, as shown in Figure 4) is positioned adjacent to the air inlet 40a and is driven by the motor 30. The same motor 30 is used not only to drive the blower 20 but also to drive the air pump 10.

[0123] For example, as shown in Figure 8, the motor 30 is connected to the blower 20 and the air pump 10 via output terminals 302 and 301 located on the left and right sides, respectively. For example, output shafts 302 and 301 may originate from the same rotating shaft within the motor 30. In another embodiment, the motor 30 may also be connected to the blower 20 and the air pump 10 sequentially via output terminals on the same side (e.g., output terminal 301 on the left side).

[0124] In this embodiment, the blower 20, motor 30, and air pump 10 are preferably arranged sequentially along a first direction a (the direction of the length or width of the housing 40, where the first direction a in FIG. 9b is the width direction). However, since the air pump itself is L-shaped, the blower 20, motor 30, and air pump 10 together form an L-shaped structure.

[0125] The housing 40 has an air duct 40b inside.

[0126] Preferably, a portion of the blower channel 40b is located between the air pump 10 and the housing 40; more preferably, the space between the air pump 10 and the housing 40 forms a portion of the blower channel 40b.

[0127] The housing 40 can refer to the outer shell frame of the air compressor / blower, or it can be the inner shell frame (e.g., the inner shell frame 410 in Figure 9b). As shown in Figure 9b, the blower channel 40b may also be formed by a portion of the outer shell frame 40 and a portion of the inner shell frame 410.

[0128] Moreover, preferably, a portion of the blower channel 40b is located between the motor 30 and the housing 40, and more preferably, the space between the motor 30 and the housing 40 forms a portion of the blower channel 40b.

[0129] More preferably, the air compressor and blower also includes an air duct component 60 (as shown in Figure 3). The air duct component 60 is located in the air outlet direction of the blower 20. The air duct component 60 facilitates the guidance of airflow from the blower 20 into the blower channel 40b. To make the structure more compact, the air duct component 60 is preferably installed around at least a portion of the motor 30 (or the air pump 10). For example, the air duct component 60 is provided with a mounting hole 60a, in which at least one of the motor 30 and the air pump 10 is fixed.

[0130] The outer casing 40 is provided with an air outlet 50. The air outlet 50 may include a first interface 51 and a second interface 52. The first interface 51 is used to receive an external blower, and the second interface 52 is used to receive an external inflation device. The outlet end of the air pump 10 may be connected to an air outlet pipe 54.

[0131] In this embodiment, the parts that are the same as those in the embodiments of Figure 1 and Figure 2 will not be described again.

[0132] It is worth noting that due to the L-shaped air pump design, the overall blower channel 40b also presents an L-shape. For example, one part is the airflow channel formed by the space between the motor 30 and the housing 40, and another part is the airflow channel formed by the space between the piston pipe 12 and the housing 40. The two are perpendicular to each other and form an L-shape.

[0133] Correspondingly, the air outlet 50 (first interface 51 and second interface 52) is also located on the housing surface perpendicular to the air inlet 40a. Therefore, the overall blower duct is L-shaped.

[0134] Furthermore, as shown in Figure 9b, the air pump and blower can also have an energy storage module 90, a main control board 80, etc., installed inside the casing. For example, the energy storage module 90 and / or the main control board 80 can be located in the space / corner outside the L-shaped blower channel 40b (e.g., the space / corner outside the blower channel 40b is divided by the inner casing frame 410).

[0135] The L-shaped structure design of this embodiment can effectively utilize two-dimensional space and prevent the unidirectional dimensions of the finished product from being too long and narrow, which may be beneficial for reducing storage size.
