[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] like Figure 1 and Figure 2 As shown, the air-inflating and air-blowing machine provided in the embodiment of the present invention includes an air pump 10 , an air-blowing device 20 , a motor 30 and a shell 40 , such as a casing 40 .

[0040] The motor 30 is connected to the blowing device 20 and the air pump 10 to drive the blowing device 20 and / or the air pump 10 to operate.

[0041] The air pump 10 , the blowing device 20 and the motor 30 are all disposed in the housing 40 .

[0042] In a preferred embodiment, the blowing device 20, the motor 30, and the air pump 10 are sequentially arranged along a first direction of the housing 40 (for example, the length or width direction of the housing, Figure 2 The length direction is shown).

[0043] The housing 40 is provided with an air inlet 40a. The air blowing device 20 (for example, an impeller 20, such as Figure 4 The airflow enters the air blowing device 20 from the air inlet 40a on the housing, and then enters the air blowing channel 40b. The air blowing channel 40b is used to guide the circulation of the air blowing airflow in the housing 40. The air blowing channel 40b is connected to the air blowing device 20 and is also connected to the air outlet 50.

[0044] Preferably, a portion of the air blowing channel 40 b is located between the air pump 10 and the housing 40 . Further preferably, the space between the air pump 10 and the housing 40 forms a portion of the air blowing channel 40 b .

[0045] Moreover, preferably, a portion of the air blowing passage 40 b is located between the motor 30 and the housing 40 , and further preferably, a space between the motor 30 and the housing 40 forms a portion of the air blowing passage 40 b .

[0046] The housing 40 is provided with a first interface 51 and a second interface 52. The first interface 51 is used to receive an external air blowing device, and the second interface 52 is used to receive an external inflatable 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 air blowing device 20 for the air blowing device 20 to discharge air, and the second interface 52 / air outlet 52a is connected to the air pump 10 for the air pump 10 to discharge air.

[0047] In a preferred embodiment, the second interface 52 is disposed inside 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. Further preferably, the second interface 52 is coaxially disposed with the first interface 51, for example, the second interface 52 and the first interface 51 form concentric rings / concentric circles, one inside and one outside.

[0048] In another embodiment, the first interface 51 and the second interface 52 may be two interfaces that do not overlap each other, that is, two independent interfaces.

[0049] It should be noted that when the air pump 10 inflates the device to be inflated through the second interface 52, high-pressure gas can be injected into the device to be inflated. Therefore, the device to be inflated is generally a device that needs to be injected with high-pressure gas, such as a tire of a car. When the air blowing device 20 blows air into the device to be inflated through the first interface 51, a large amount of gas can be quickly injected into the device to be inflated. Therefore, the device to be inflated is generally a device that needs a large amount of gas, such as an air mattress. The present invention can choose to use the air pump 10 or the air blowing device 20 according to the usage scenario, or use the air pump 10 and the air blowing device 20 at the same time.

[0050] It should be noted that the present invention preferably uses the same motor 30 to drive the blowing device 20 and the air pump 10. For example, the present invention preferably only has one motor 30 to drive the air pump 10 and the blowing device 20 to operate.

[0051] The motor 30 is drivingly connected to the blowing device 20 , and the motor 30 is drivingly connected to the air pump 10 .

[0052] For example Figure 8 As shown, one output end (output shaft) 302 of the motor 30 is connected to the air blowing device 20, for example, connected to the impeller of the air blowing device 20, to drive the impeller to rotate; the other output end (output shaft) 301 of the motor 30 is connected to the air pump 10, for example, connected 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 assembly, the motor drives the piston assembly 11 and drives the piston rod to move.

[0053] 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 (belong to the same output shaft). For example, the output shaft 302 and the output shaft 301 are output from the same rotating shaft in the motor 30.

[0054] exist Figure 8 In the illustrated embodiment, the motor 30 is drivingly connected to the blowing device 20 and the air pump 10 via output terminals 302 and 301 located on the left and right sides, respectively.

[0055] In another embodiment, the motor 30 may also be connected to the blower 20 and the air pump 10 in sequence through the output end on the same side (e.g., the output end 301 on the left side). For example, the output end 301 of the motor 30 is first connected to the blower 20 along the axial direction (e.g., the impeller of the blower 20 is fixedly connected to the output end 301 through a fixing member), and then connected to the air pump 10 (e.g., the air pump 10 is connected to the output end 301 through a gear assembly).

[0056] The motor 30 of the present invention can drive the air pump 10 and the blowing device 20 to operate simultaneously.

[0057] In a preferred embodiment, when the motor 30 is running, the air pump 10 and the air blowing device 20 are both running at the same time. When the motor 30 stops, the air pump 10 and the air blowing device 20 are both stopped.

[0058] In another embodiment, the motor 30 of the present invention can also drive the air pump and the blowing device 20 to operate separately, that is, the motor 30 can be configured to drive the air pump 10 to operate alone while the blowing device 20 does not operate in the inflation mode, and / or the motor 30 can also be configured to drive the blowing device 20 to operate alone while the air pump 10 does not operate in the blowing mode.

[0059] It should be noted that the first interface 51 and the second interface 52 of the present invention may be a combined interface. Of course, the first interface 51 and the second interface 52 may also be independent interfaces.

[0060] In the present embodiment, the air pump 10 can inflate the device to be inflated through the second interface 52, and the air blowing device 20 can blow air to the device to be blown through the first interface 51. Moreover, when inflating and / or blowing, the air pump 10 and the air blowing device 20 are driven by the same motor 30, so compared with the prior art, the space occupied by the additional motor 30 can be saved, and the outer shell 40 can be reduced to reduce the volume and weight of the air pump and air blower, which is convenient for carrying and use. For example, in actual application scenarios, the air pump and air blower can be used as an emergency device for a car, so it is generally placed in the car for a long time. Reducing the volume and weight of the air pump and air blower can make it more convenient to carry and use in emergencies.

[0061] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the air blowing device 20 and the air pump 10 are arranged in sequence along the first direction a. Preferably, the first direction a is the extension direction of the length of the housing 40, that is, the longitudinal direction of the housing 40. Such an arrangement can make the air blowing device 20 and the air pump 10 more compactly arranged in the housing 40, which is conducive to the structural integration in the housing 40, and further makes the air blowing machine miniaturized for easy carrying and use.

[0062] like Figure 1 and Figure 2As shown, in the embodiment of the present invention, an air outlet 50 is provided at the end of the shell 40 along the first direction a, and the air outlet 50 includes a first interface 51. An air blast channel 40b is provided between the air pump 10 and the inner wall of the shell 40, and the air blast device 20 is connected to the air outlet 50 through the air blast channel 40b, for example, connected to the air outlet hole 51a. It can be understood that there is a certain distance between the first interface 51 and the air blast device 20, and the air blast channel 40b can guide the air discharged by the air blast device 20 to discharge. In this way, it is conducive to the directional air discharge of the air blast device 20. In addition, since the air blast channel 40b directly utilizes the space between the air blast device 20 and the inner wall of the shell 40, it will not occupy additional space of the air blasting machine. It should be noted that in this embodiment, the air blast channel 40b can be a pipe provided between the air pump 10 and the inner wall of the shell 40, and of course, it can also be a channel formed by the space between the air pump 10 body and the inner wall of the shell 40.

[0063] Exemplarily, the space between the air pump 10 body and the inner wall of the housing 40 forms at least part of the air blowing channel 40b. In this way, on the one hand, the structure of the air pump 10 can be simplified, and its weight can be reduced for easy carrying; on the other hand, when the air blowing device 20 blows air along the air blowing channel 40b, the airflow in the air blowing channel 40b can also provide sufficient and stable ambient airflow for the air pump 10. When the air pump 10 is working, the airflow in the air blowing channel 40b can directly enter the air pump 10 as the ambient gas of the air pump. Therefore, such a setting is also beneficial to the airflow and air outlet of the air pump 10.

[0064] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, an air inlet 40a is provided at one end of the outer shell 40, for example, an air inlet 40a is provided at the head end along the first direction a. It should be noted that since the air blowing device 20 and the air pump 10 are arranged in sequence along the first direction a. Therefore, the air inlet of the air blowing device 20 is close to the air inlet 40a. In this way, it is convenient to introduce the outside air into the air blowing machine through the air blowing device 20. In combination with the above-mentioned first interface 51 being arranged at the end of the outer shell 40 along the first direction a, the air inlet and air outlet of the air blowing device 20 are arranged along the length direction of the outer shell 40, and under the guidance of the air blowing device 20, the air can flow rapidly along the first direction a. In this way, it is more conducive to the air outlet of the air blowing device 20 so as to provide a large amount of gas to the equipment to be blown.

[0065] like Figure 1 and Figure 2As shown, in the embodiment of the present invention, a second interface 52 is provided at the end of the housing 40 along the first direction a. The gas flowing into the air through the air inlet 40a and entering the air blast channel 40b can be used as ambient gas and enter from the air inlet of the air pump 10, and under the operation of the air pump 10, the high-pressure gas is discharged from the second interface 52, so as to provide high-pressure gas to the equipment to be inflated. It should be noted that in the present invention, the outside air can be accelerated to enter the air blast channel 40b through the guidance of the air blast device 20, so as to provide the air pump 10 with stable and sufficient ambient gas to improve the inflation efficiency. Of course, when the air blast device 20 is not working, the outside gas can also pass through the air blast device 20 and enter the air blast channel 40b to enter the air pump 10, so as to inflate the air pump 10. In addition, the first interface 51 and the second interface 52 are both arranged at the end of the housing 40, so that the user can conveniently connect the equipment to be blown and / or the equipment to be inflated for easy use.

[0066] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the motor 30 is arranged between the air pump 10 and the blower 20. The motor 30 can be close to the blower 20 and the air pump 10, which makes it more convenient for the motor 30 to be driven and connected with the air pump 10 and the blower 20, and the structural connection is simple, and there is no need to extend the drive shaft additionally, so that the structure of the air pump and blower is more compact and reasonable. In addition, by arranging the motor 30 between the air pump 10 and the blower 20, the blower 20 can also be closer to the air inlet 40a, so that the blower 20 can guide the outside air into the air pump and blower. It can be understood that after such arrangement, the air pump 10, the motor 30, and the blower 20 are arranged in sequence along the first direction a, and the whole can also better fit the shape of the housing 40, further making the air pump and blower miniaturized, so as to facilitate its carrying and use. Of course, in other embodiments, the motor 30 can also be arranged on the side of the blower 20 away from the air pump 10. That is, the motor 30, the blowing device 20, and the air pump 10 are arranged in sequence along the first direction a.

[0067] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, a first output shaft 301 is provided at one end of the motor 30, and a second output shaft 302 is provided at the other end of the motor 30. The first output shaft is used to drive the air pump 10, and the second output shaft is used to drive the blower 20. In this way, the blower 20 and the air pump 10 can be driven by the motor 30 to achieve air and wind output.

[0068] 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. In this way, the user can close 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 to operate alone according to the use needs; or close 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 to operate alone; or, the clutches at both ends of the motor 30 can be closed at the same time to enable the motor 30 to drive the air pump 10 and the blower 20 to operate at the same time.

[0069] 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 is directly connected to the second drive shaft of the air blowing device 20. In this way, the user can close the clutch between the first output shaft of the motor 30 and the first drive shaft of the air pump 10 according to the use needs, so that the motor 30 drives the air pump 10 and the air blowing device 20 to operate at the same time; or, the clutch can be not activated to drive the air blowing device 20 alone to operate.

[0070] In some embodiments, the first output shaft of the motor 30 is directly connected to the first drive shaft of the air pump 10, and a clutch is provided between the second output shaft of the motor 30 and the second drive shaft of the air blowing device 20. In this way, the user can close the clutch between the second output shaft of the motor 30 and the second drive shaft of the air blowing device 20 according to the use needs, so that the motor 30 drives the air pump 10 and the air blowing device 20 to operate at the same time; or, the clutch can be not activated to drive the air pump 10 alone to operate.

[0071] Exemplarily, 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 the friction plate are arranged on the input end, and the input end is connected to the output shaft. The armature is arranged on the output end, and the output end is connected to the drive shaft. When the clutch is not powered, the input end and the output end are disconnected and the torque cannot be transmitted. When the clutch is powered, the armature is adsorbed on the friction plate through the electromagnetic plate, and the 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 described here.

[0072] like Figure 1 As shown in FIG. 3 , in the embodiment of the present invention, the air-inflating and air-blowing machine further includes an air duct component 60 .

[0073] The air duct member 60 is located in the air outlet direction of the air blowing device 20. The air duct member 60 is conducive to guiding the airflow from the air blowing device 20 to the air blowing channel 40b. In order to make the structure more compact, the air duct member 60 is preferably installed at a position surrounding at least a portion of the motor 30 (or the air pump 10).

[0074] For example, the air duct component 60 is provided with a mounting hole 60a, and at least one of the air blowing device 20, the motor 30 and the air pump 10 is fixed to the mounting hole 60a. On the one hand, the air duct component 60 provided can stably mount at least one of the air blowing device 20, the motor 30 and the air pump 10. On the other hand, the air duct component 60 can serve as an air guide structure inside the air blowing machine to direct the airflow of the air blowing device 20 into the air blowing channel 40b, so as to facilitate the air outlet of the air blowing device 20 and the air outlet of the air pump 10. It should be known that the air duct component 60 can be used to fix one of the air blowing device 20, the motor 30 and the air pump 10 alone, or to fix two or more of the air blowing device 20, the motor 30 and the air pump 10 at the same time, as long as the air duct component 60 can ensure the smooth air outlet of the air blowing device 20 and the smooth air outlet of the air pump 10.

[0075] like Figure 2 As shown in FIG3 , illustratively, the circumferential side of the air duct member 60 is adapted to and snapped onto the inner wall of the housing 40, so that the air duct member 60 can be stably installed to achieve stable support for at least one of the installed blower device 20, motor 30, and air pump 10. In another embodiment, the air duct member 60 and the housing 40 can be integrated.

[0076] like Figure 1 As shown in FIG. 3 , illustratively, the mounting hole 60a is located in the middle of the air duct component 60 on the housing 40 perpendicular to the first direction a, so that at least one of the blower 20, the motor 30 and the air pump 10 can be stably mounted in the middle of the housing 40, so that the blower 20, the motor 30 and the air pump 10 are centrally arranged in the housing 40 as a whole, and in particular, the impeller of the blower 20 can be centrally arranged, so that the blower 20 is compactly arranged in the housing as a whole. In this example, the air inlet 40a, the air outlet 52a and the air outlet 51a are also located in the middle of the housing 40 perpendicular to the first direction a, so as to facilitate the stable and balanced air and wind outlet of the blower.

[0077] like Figure 2 As shown in FIG. 3 , the mounting hole 60a of the air duct member 60 fixes the motor 30. When the motor 30 is located between the air blowing device 20 and the air pump 10, the motor 30 can be firmly clamped in the mounting hole 60a and ensure stable driving of the air pump 10 and / or the air blowing device 20. In this example, one end of the motor 30 is adapted to the mounting hole 60a to achieve stable installation of the motor 30.

[0078] like Figure 1 As shown in FIG3 , in the embodiment of the present invention, the air blowing machine further includes an air duct member 60, the air duct member 60 is provided with an air blowing through hole 60b, the air blowing device 20 is provided with an air outlet, and the air outlet is connected to the air outlet hole 51a through the air blowing through hole 60b. The air duct member 60 can guide the air blowing device 20 to discharge air, so as to treat the air blowing device to discharge air, thereby improving the air blowing efficiency.

[0079] like Figure 2 As shown in FIG. 3 , the blast holes 60b are exemplarily arranged around the outer periphery of the air duct member 60. The blast holes 60b can be arranged opposite to the air outlet of the air blast device 20, so as to guide the air outlet of the air blast device 20. Specifically, the air blast device 20 is arranged around the mounting hole 60a, so that the air duct member 60 can stabilize the internal structure of the air blast device on the one hand, and guide the air outlet of the air blast device 20 on the other hand, so as to improve the air blast efficiency.

[0080] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the air blowing device 20, the motor 30 and the air pump 10 are arranged in sequence along the first direction a, the air duct component 60 is arranged at a position close to the air blowing device 20, and the mounting hole 60a is used to fix the end of the motor 30 close to the air blowing device 20, so that the second output shaft of the motor 30 can stably support and drive the air blowing device 20 to move. The air blowing through hole 60b is arranged around the mounting hole 60a, one end of the air blowing through hole 60b is connected to the air outlet of the air blowing device 20, and the other end is connected to the air blowing channel 40b formed between the motor 30, the air pump 10 and the inner wall of the outer shell 40. In this way, the air outlet of the air blowing device 20 is connected to the air outlet 51a through the air blowing through hole 60b and the air blowing channel 40b in sequence. As shown Figure 2 As shown, when the air blowing device 20 is in operation, the air discharged therefrom can pass through the air blowing through hole 60 b , the air blowing passage 40 b and the air outlet hole 51 a , so that the air blowing device 20 can discharge air.

[0081] like Figure 1 and Figure 4 As shown, in the embodiment of the present invention, the air blowing device 20 includes an impeller, and the motor 30 is connected to the impeller to drive the impeller to rotate. Under the rotation of the impeller, the air in the air inlet of the air blowing device 20 can be guided to the air outlet to achieve air outlet.

[0082] like Figure 1 and Figure 4As shown, in the embodiment of the present invention, the driving axis (rotation axis) of the impeller is extended along the first direction a. In this way, the impeller can discharge air along the first direction a. In combination with the above embodiment, the air discharged by the air blowing device 20 can be discharged from the air outlet 51a along the first direction a, so as to facilitate efficient air discharge of the air blowing device 20.

[0083] like Figure 1 and Figure 4 As shown, in the embodiment of the present invention, the impeller includes a rotating member 21 and a plurality of blades 22 . The rotating member 21 is connected to the motor 30 , and the plurality of blades 22 are connected around the circumference of the rotating member 21 .

[0084] Preferably, the impeller further has a windshield 23. Preferably, the windshield 23 is located on a plane perpendicular to the rotation axis (first direction a) of the impeller. The windshield 23 is arranged on a side close to the air inlet 40a. The windshield 23 is used to block the airflow from flowing in the direction of the air inlet, thereby promoting the airflow to flow in the direction of the air outlet. In addition, since the blades 22 of the air blowing device 20 are often relatively large in area, the windshield 23 can also play a fixing and strengthening role to prevent the blades 22 from breaking when rotating.

[0085] The rotating member 21 and the plurality of blades 22 are connected to the wind shield 23. An air inlet is provided around the plurality of blades 22, and an air outlet is provided on the side of the plurality of blades 22 away from the wind shield 23. The rotating member 21 is driven to rotate by the motor 30 to drive the plurality of blades 22 to rotate around the rotating member 21. Through the rotation of the plurality of blades 22, the air around the plurality of blades 22 is guided to the air outlet, and the airflow flows from the side of the impeller to the axial direction, so that the air blowing device 20 can discharge air.

[0086] In one embodiment, the plane / arc surface where the blade 22 is located is perpendicular to the wind shield 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, in order to strengthen the direction of the wind, the plane / arc surface where the blade 22 is located may be non-perpendicular to the wind shield 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 inclination angle.

[0087] In this embodiment, the windshield 23 is arranged toward the air inlet 40a, which can prevent external dust from directly entering the air blowing device 20 and other structures, so as to ensure that the air blowing machine can work stably. Of course, in other embodiments, the windshield 23 may not be arranged, so that the side of the multiple blades 22 facing the air inlet 40a is the air inlet part, and the airflow flows directly along the axial direction of the impeller to realize the air outlet of the air blowing device 20. In particular, when the plane / arc surface where the blades 22 are located is not parallel to the rotation axis (first direction a) of the impeller 22, and a certain inclination angle is formed, even without a windshield, the airflow can flow in the air outlet direction.

[0088] like Figure 3b As shown, the air duct member 60 of the present invention comprises 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 .

[0089] The outer wall 602 may be in the shape of a ring (or a part of a ring); the inner wall 601 may be in the shape of a ring (or a part of a ring).

[0090] The inner wall 601 forms a mounting hole 60a, which can be used to mount at least a part of the motor 30 or the air pump 10 therein, thereby making the structure more compact.

[0091] A notch 60c may also be formed on the outer wall 602 and the inner wall 601, for example, for routing the wires of the motor 30.

[0092] A plurality of partitions 603 are provided between the inner wall 601 and the outer wall 602. Preferably, the plane / arc surface where the partition 603 is located is not parallel to the rotation axis (first direction a) of the impeller 22, but forms a certain inclination angle (such as Figure 3b As shown), a guide air duct 60b is formed from the air inlet direction to the air outlet direction (from the air inlet 40 to the air blast passage 40b).

[0093] like Figure 1 and Figure 4 As shown, in the embodiment of the present invention, the blast hole (guide air duct) 60b is arranged along the first direction a, tilted toward 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 has a certain angle with the circumference of the impeller. The blast hole 60b can adapt to the outlet airflow of the blast device 20 through the above-mentioned tilted arrangement, so that the blast device 20 can efficiently discharge a large amount of air, thereby improving the blast efficiency of the blast device 20.

[0094] Exemplarily, the air duct member 60 is provided with a plurality of air blast holes 60b, and adjacent air blast holes 60b are provided with obliquely disposed partitions 603 to form the above-mentioned obliquely disposed air blast holes 60b.

[0095] like Figure 1 As shown, in the embodiment of the present invention, the air pump and blower also includes an air outlet pipe 54 for the air outlet of the air pump 10.

[0096] 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, and the piston is provided in the piston pipe 12. The motor 30 is connected to the piston assembly 11 to drive the piston to reciprocate in the piston pipe 12. For example, the motor 30 drives the piston assembly 11 through gear meshing, and the piston assembly 11 is connected to drive the piston rod, and the piston rod moves in the piston pipe 12.

[0097] In one embodiment, the air pump 10 is a piston pump, one side of the piston assembly 11 is an air inlet, and the motor 30 drives the piston to reciprocate in the piston pipe 12. For example, the motor 30 can drive the transmission member of the piston assembly 11 to rotate, thereby driving one end of the piston to perform a yaw motion. When one end of the piston performs a yaw motion, the other end can reciprocate in the piston pipe 12 to repeatedly press the gas into the piston pipe 12, and then the high-pressure gas can be discharged from the outlet pipe 54 and the outlet hole 52a to output high-pressure air. Of course, in other embodiments, the air pump 10 can also be a diaphragm pump.

[0098] Exemplarily, 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 hole 52a through the air outlet pipe 54 to facilitate stable air outlet. In the present invention, the air pump 10 can be selectively installed at different positions of the housing 40 along the first direction a as needed. In this way, the air pump 10 and the air outlet hole 52a can be connected by simply replacing the air outlet pipe 54 of different lengths to ensure stable air outlet.

[0099] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the piston assembly 11, the piston pipe 12 and the air outlet pipe 54 are arranged in sequence along the first direction a. Such an arrangement can make the air pump 10 more consistent with the shape of the housing 40, and be arranged more compactly in the housing 40, which is conducive to the structural integration in the housing 40, and further makes the air pump 10 miniaturized for easy carrying and use.

[0100] like Figure 1 and Figure 2As shown, in the embodiment of the present invention, the piston pipe 12 and the air outlet pipe 54 are both extended along the first direction a. Such an arrangement, on the one hand, can make the partial structure of the air pump 10 and the connected structure more consistent with the shape of the outer shell 40, so that the structure inside the outer shell 40 is more compact, which is conducive to the integration of the structure inside the outer shell 40. On the other hand, when the air pump 10 is exhausting air, it is also exhausting air along the first direction a. Combined with the above embodiment, the air outlet direction of the blowing device 20 is exhausting air along the first direction a. In this way, the air outlet and air outlet of the air pump and blower can be more comfortable, will not affect each other, and are easy to use.

[0101] like Figure 1 and Figure 5 As shown, in the embodiment of the present invention, a gas nozzle structure 50 is also provided, and the gas nozzle structure 50 includes the above-mentioned first interface 51 and the second interface 52, and the second interface 52 is arranged in the first interface 51. The first interface 51 is used to receive an external air blowing device, and the second interface 52 is used to receive an external inflatable device.

[0102] It should be noted that since the gas output by the air pump 10 is high-pressure gas, when the high-pressure gas is discharged through the air outlet 52a, high temperature will be generated at the second interface 52, which may easily burn the human body.

[0103] The air nozzle structure 50 of this embodiment can be used to inflate the inflatable device and blow air to the air blowing device. When the inflatable device is inflated through the second interface 52 and the inflatable device is inflated through the air pump 10, since the second interface 52 is located in the first interface 51, the user can avoid direct contact with the second interface 52 and being burned by the second interface 52. In addition, the user can select a mode according to demand (or in the default mode), and turn on the air blowing device 20 while the air pump 10 is working, so that the wind of the air blowing device 20 can pass through the air outlet 51a. Since the second interface 52 is located in the first interface 51, the wind passing through the air outlet 51a can further dissipate heat and cool the second interface 52. Even if the user accidentally touches the second interface 52, it can avoid being burned by the second interface 52, thereby improving the user's experience. It should be noted that when inflating the inflatable device, the user can also not turn on the air blowing device 20, but only turn on the air pump 10 to inflate the inflatable device through the air outlet 52a.

[0104] In addition, the embodiment of the present invention can also receive an external blower device through the first interface 51, and blow air to the blower device 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), and turn on the air pump 10 while the blower device 20 is working, so that the gas discharged by the air pump 10 coincides 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 to the blower device, the user may not turn on the air pump 10, but only turn on the blower device 20 to blow air to the blower device through the air outlet 51a.

[0105] like Figure 1 and Figure 5 As shown, in the embodiment of the present invention, the air nozzle structure 50 also includes an air outlet pipe 54, one end of which is connected to the 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, and the air outlet channel is used for the air pump 10 to exhaust air. 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 of the air outlet pipe 54 and the air pump 10 can refer to the above. In this embodiment, since the air outlet pipe 54 is connected to the air outlet hole 52a, when the inflatable device to be inflated is inflated by the air pump 10, the high-pressure gas is exhausted through the air outlet channel. In this way, the high-pressure gas will be exhausted from the position of the air outlet pipe 54 or the air outlet hole 52a, reducing the heat directly generated to the second interface 52, thereby reducing the temperature of the second interface 52 to a certain extent to avoid scalding the user.

[0106] Exemplarily, one end of the air outlet pipe 54 is flush with the outer surface of the second interface 52, so that the second interface 52 is actually sleeved on the end of the air outlet pipe 54, and the high-pressure gas is actually discharged from the end of the air outlet pipe 54, reducing 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.

[0107] Exemplarily, a step protrusion is provided on the circumferential side of the outlet pipe 54. When one end of the outlet pipe 54 is connected to the outlet hole 52a, one end of the outlet pipe 54 is adapted and embedded in the outlet hole 52a, and the step protrusion is pressed against the side of the second interface 52 facing the inside of the shell 40, so as to achieve a stable connection between the outlet pipe 54 and the outlet hole 52a.

[0108] like Figure 6As shown, in the embodiment of the present invention, the housing 40 is further provided with a fixing component 53, one end of the fixing component 53 surrounds and wraps 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 is provided to stably connect the first interface 51 and the second interface 52 to ensure that the second interface 52 can be stably supported, and the second interface 52 can be stably connected to the air pump 10 for the air pump 10 to exhaust air. Of course, in other embodiments, the other end of the fixing component 53 can be fixedly connected to the housing 40 to stably support the second interface 52.

[0109] like Figure 6 As shown, in the embodiment of the present invention, a plurality of air outlet holes 51a are provided, and the plurality of air outlet holes 51a are spaced apart from the air outlet hole 52a. The air output can be increased by providing the plurality of air outlet holes 51a, so as to achieve a better blowing effect of the blowing device 20. Moreover, the plurality of air outlet holes 51a are spaced apart from the air outlet hole 52a, so that the air blowing machine can be independent of each other when blowing air and blowing gas, so as to facilitate use. Of course, in other embodiments, the plurality of air outlet holes 51a can be connected into one, and the air outlet is achieved through a large air outlet.

[0110] Exemplarily, the area between the second interface 52 and the first interface 51 is divided into a plurality of air outlets 51 a by the fixing assembly 53 , so that the second interface 52 is supported and air can be discharged through the air outlets 51 a .

[0111] like Figure 6 As shown, in a preferred embodiment of the present invention, a plurality of air outlet holes 51a are arranged around the air outlet hole 52a. For example, a plurality of air outlet holes 51a are arranged around the air outlet hole 52a as the center. In this way, when the plurality of air outlet holes 51a discharge air through the air blowing device 20, they can all dissipate heat and cool down the second interface 52. Even if the user touches the second interface 52 by mistake, the user can avoid being burned by the second interface 52, thereby improving the user experience. In addition, such an arrangement enables the air blowing machine to also discharge air and / or air in a balanced and stable manner.

[0112] like Figure 6As shown, exemplarily, the fixing assembly 53 includes a plurality of connectors 531 arranged at intervals around the second interface 52, and the two ends of the connectors 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 constructed through the inner wall of the first interface 51, the plurality of connectors 531 and the outer wall of the second interface 52. Further, the ends of the connectors 531 are narrow in the middle, so that, on the one hand, stable and reliable support for the second interface 52 can be ensured, and on the other hand, the air outlet 51a can be enlarged as much as possible to ensure that the air outlet 51a can discharge a larger amount of air. Further, the plurality of connectors 531 are evenly spaced around the second interface 52. For example, the fixing assembly 53 includes three connectors 531 evenly spaced around the second interface 52.

[0113] like Figure 1 and Figure 6 As shown, in the embodiment of the present invention, an air outlet channel is formed between the housing 40, the fixing assembly 53, the air outlet hole 51a and the outer wall of the air outlet pipe 54, and the air outlet channel is used to supply air to the air blowing device 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 blowing machine.

[0114] Exemplarily, the air outlet channel is connected to the above-mentioned air blowing channel 40b, and the air discharged by the air blowing device 20 passes through the air blowing channel 40b and the air outlet channel to achieve air outlet.

[0115] like Figure 6 As shown, in the embodiment of the present invention, the first interface 51 is provided with a first end away from the inflator and blower, and the second interface 52 is provided with a second end away from the inflator and blower, and the second end is located on the side of the first end facing the housing 40. It can be understood that the second interface 52 is located inside the first interface 51 facing the inflator and blower, so that the user can be further prevented from directly contacting the second interface 52 and being burned by the second interface 52.

[0116] like Figure 6 As shown, in the embodiment of the present invention, the first interface 51 protrudes from the surface of the housing 40. In this way, on the one hand, it is convenient to connect the first interface 51 with the device to be blown, and on the other hand, it can also realize the structure in which the second interface is located inside the first interface 51 facing the air blowing machine.

[0117] like Figure 6 As shown, in the embodiment of the present invention, the first interface 51, the second interface 52 and the fixing part are all integrally formed on the outer shell 40. That is to say, when manufacturing 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.

[0118] like Figure 6 As shown, in the embodiment of the present invention, the first interface 51 and the second interface 52 are both circular interfaces, so as to facilitate connection with the equipment to be blown and the equipment to be inflated.

[0119] like Figure 7 As shown, in the embodiment of the present invention, the air nozzle structure 50 further includes a fixing member, which is arranged at the first interface 51 or the second interface 52, and is used to be fixedly connected to the device to be blown or the device to be inflated. The air nozzle structure 50 is fixed to the air-using device by the fixing member, so as to blow air to the device to be blown or inflate the device to be inflated.

[0120] like Figure 7 As shown, in the embodiment of the present invention, the fixing member may include a first fixing member 71, and the first fixing member 71 is disposed around the outside of the first interface 51, and is used to at least guide the air outlet of the blowing device 20 to the equipment to be blown. In this way, it is convenient to blow air to the equipment to be blown. It should be noted that when blowing air to the equipment to be blown, the blowing device 20 and the air pump 10 can be turned on at the same time to blow air to the equipment to be blown at the same time to increase the blowing volume, and the blowing device 20 can be turned on alone to blow air to the equipment to be blown.

[0121] like Figure 7 As shown, exemplarily, a protrusion is provided on the outer side of the first interface 51, and an L-shaped snap-in groove is provided on the inner wall of the interface of the first fixing member 71 connected to the first interface 51, and one end of the L-shaped snap-in 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 sleeve the interface of the first fixing member 71 on the outer side of the first interface 51 so that the protrusion is placed in the L-shaped snap-in groove, and then rotate the interface of the first fixing member 71 so that the protrusion is stuck in the L-shaped snap-in groove, and the interface of the first fixing member 71 is not easy to be 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. To ensure that the air blowing machine can achieve stable 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-in methods, or can also be connected by magnetic attraction or threading, without limitation.

[0122] like Figure 7 As shown, exemplarily, the first fixing member 71 is trumpet-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 wind guidance, while increasing the air flow rate of the equipment to be blown, so as to increase the blowing efficiency of the air-blowing machine.

[0123] In another embodiment, the fixing member may include a second fixing member, which is disposed around the air outlet 52a and the air outlet 51a, and is used to guide the air outlet of the air pump 10 to the device to be inflated. In this way, it is convenient to inflate the device to be inflated. It should be noted that when blowing air for the device to be inflated, the blowing device 20 and the air pump 10 can be turned on at the same time to dissipate heat and cool the second interface 52 while inflating, and the air pump 10 can be turned on alone to inflate the device to be inflated.

[0124] Exemplarily, the inner wall of the second interface 52 or the inner wall of the air outlet pipe 54 is provided with an internal thread, the interface end of the second fixing member is provided with an external thread, and 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 blowing machine 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-on method or a magnetic method, without limitation.

[0125] Exemplarily, the second fixing member is trumpet-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, thereby increasing the air flow rate of the inflatable device to be inflated, so as to improve the inflation efficiency of the inflator.

[0126] In addition, the fixing member of the present invention may be a set of kits, such as a kit including a first fixing member 71 and a second fixing member 72. When the blower is received outside, the first fixing member 71 is used to connect the blower and the device to be blown. When the inflatable device is received outside, the second fixing member 72 is used to connect the blower and the device to be inflated.

[0127] In the inflating and blowing machine of the present invention, the fixing part is connected to the equipment to be blown or inflated by snapping or threading, so as to ensure the stable connection between the fixing part and the equipment to be blown or inflated, so as to achieve stable blowing and inflation.

[0128] like Figure 1 and Figure 2As shown, in the embodiment of the present invention, the inflator and blower machine further includes a switch (not shown), which is disposed on the housing 40. The switch is used to control the inflator and blower machine to enter different modes, such as an inflating mode, a blowing mode, or an inflating and blowing mode. Through the provided switch, the user can select the use mode of the inflator and blower machine to improve the user experience. Among them, in the inflation mode, the motor 30 only drives the air pump 10 to operate, but does not drive the blowing device 20 to operate, and the air inflation and blowing machine can be used to inflate the inflatable device; the blowing mode is that the motor 30 only drives the blowing device 20 to operate, and the air pump 10 does not operate, and the air inflation and blowing machine can be used to blow air to the inflatable device; the inflation and blowing mode is that the motor 30 simultaneously drives the air pump 10 and the blowing device 20 to operate, and the air inflation and blowing machine can be used to blow air to the inflatable device, and the air output volume is increased by the air pump 10, or, the air inflation and blowing machine can also be used to inflate the inflatable device, inflate it by the air pump 10, and the blowing device 20 can cool the air nozzle structure 50 by the air output.

[0129] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, the air pump and blower also includes an energy storage module (not shown) and an emergency starting power supply output interface (not shown), the energy storage module is arranged in the housing 40, and the emergency starting power supply output interface is electrically connected to the energy storage module. Electric energy can be stored through the energy storage module, and when necessary, emergency power supply can be supplied to the car through the emergency power supply output interface, for example, emergency starting of the car can be provided. In this way, the air pump and blower is more convenient to carry and use. It should be known that the energy storage module of the present invention can also be used to power the motor 30 to enable the motor 30 to perform corresponding work.

[0130] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the inflator and blower also includes one or more of a USB interface, an AC socket, a DC interface, and a cigarette lighter socket, and the USB interface, AC socket, DC interface, emergency start power output interface, and cigarette lighter socket are electrically connected to the energy storage module. Other electronic devices can be powered through various electrical connection interfaces, and the type of electrical connection interface can be changed accordingly according to different electronic devices to achieve multi-functional power supply.

[0131] The above-mentioned various electrical connection interfaces can be provided on the housing 40 for easy connection and use.

[0132] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the air-inflating and air-blowing machine further includes an inverter module (not shown), and the energy storage module is connected to the electrical connection interface of the energy storage device through the inverter module to provide alternating current to the electrical connection interface.

[0133] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, the air pump and blower also includes a charging interface (not shown), which is electrically connected to the energy storage module. The charging interface is arranged on the housing 40, and 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.

[0134] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the air-inflating and blowing machine is also provided with a main control board (not shown in the figure), and 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 corresponding control requirements.

[0135] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the housing 40 includes a first housing 41 and a second housing 42, both of which are extended along the first direction a, and the first housing 41 is provided with a mounting groove 41a, and the above-mentioned air nozzle structure 50 and the air inlet 40a are both provided on the first housing 41. When installing the air blowing device 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 by screws, the air duct component 60 is installed at one end of the motor 30 close to 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 air blowing device 20 through the second output shaft, and supports the air blowing device 20, the second housing 42 covers the opening of the mounting groove 41a and is connected to the first housing 41, so that the air blowing device 20, the motor 30 and the air pump 10 are installed and placed in the housing 40.

[0136] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the above-mentioned main control board, energy storage module, etc. are installed in the outer shell 40, and can be arranged at the blowing channel 40b. In this way, when air is discharged through the blowing device 20, the main control board, energy storage module, etc. can also be cooled and dissipated to ensure the stable operation of the air-blowing machine.

[0137] Exemplarily, the main control board, energy storage module, etc. can be installed on the side of the motor 30 and / or the air pump 10 away from the bottom of the installation slot 41a, and located on the side of the air duct component 60 away from the air blowing device 20, so as to ensure the stable air discharge of the air blowing device 20 and stably install the main control board, energy storage module, etc. At the same time, such a setting can also make full use of the redundant space in the housing 40, without the need for additional space for installation, making the internal structure of the air blowing machine more compact, which is convenient for carrying and using.

[0138] Another embodiment of the present invention is Figure 9a and Figure 9b As shown. Figure 1 and Figure 2 The difference between the shown embodiments is that Figure 9a and Figure 9b The air pump shown in the figure uses an L-shaped air pump. Figure 9b As shown, the motor 30 drives the driving shaft of the air pump in the direction a (as shown in FIG. Figure 8 The direction a) of the motor output shaft 301 of the middle driving piston assembly 11 is perpendicular to the moving 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 feature of the commercially available L-shaped air pump.

[0139] exist Figure 9a and Figure 9b In the embodiment shown, the blower device 20, the motor 30, and the air pump 10 of the present invention are all arranged in a housing 40. The housing 40 is provided with an air inlet 40a. The blower device 20 (for example, an impeller 20, such as Figure 4 The motor 30 is arranged adjacent to the air inlet 40a and driven by the motor 30.
