[0028] Please refer to Figure 1 , Figure 2 and Figure 3 The present embodiment provides a small-volume portable air pump 100, including a shell 110 and an air-filling assembly 120. The air-filling assembly 120 includes a driver 121, a torque amplifier 122, and a cylinder 123 linearly arranged along a first direction in the shell 110. The driver 121 is driven and connected to the cylinder 123 via the torque amplifier 122. The driver 121 drives the cylinder 123 to perform piston motion through the torque amplifier 122 to realize pressurized gas delivery.

[0029] The arrangement of the driver 121, the torque amplifier 122 and the cylinder 123 is a straight line arrangement or a nearly straight line arrangement. The driver 121, the torque amplifier 122 and the cylinder 123 are arranged more regularly in the housing 110, so that the reserved storage space for the battery 140 in the housing 110 is larger, thereby increasing the volume of the battery 140 and increasing the working time of the small-volume portable air pump 100. It should be noted that the first direction can be arranged along the length direction of the housing 110.

[0030] The torque is increased by the torque amplifier 122 to increase the piston movement efficiency, so that the small-volume portable air pump 100 can achieve high-pressure delivery when it is started, so as to increase the use conditions of the small-volume portable air pump 100. Among them, the torque amplifier 122 is a multi-gear transmission.

[0031] It should be noted that the driver 121 may adopt a brushless motor, which can use a smaller motor on the basis of the same performance, thereby saving the internal space of the housing 110 and reducing the overall volume of the housing 110.

[0032] The small-volume portable air pump 100 provided in the present application includes a shell 110 and an inflatable component 120. The inflatable component 120 includes a driver 121, a torque amplifier 122 and a cylinder 123 arranged linearly along a first direction in the shell 110, so that the inflatable component 120 is arranged more regularly in the shell 110, so that the battery 140 storage space reserved in the shell 110 is larger. The driver 121 is driven and connected to the cylinder 123 through the torque amplifier 122. The driver 121 drives the cylinder 123 to perform piston movement through the torque amplifier 122 to achieve pressurized gas delivery. The torque is increased by the torque amplifier 122 to increase the piston movement efficiency, so that the small-volume portable air pump 100 can achieve high-pressure delivery when it is started.

[0033] In a feasible embodiment of the present application, Figure 1 , Figure 2 and Figure 3 As shown, an air inlet 111 and an air outlet 112 are provided on the shell 110. The air inlet 111 is located on the side of the driver 121 away from the cylinder 123, and the air outlet 112 is located on the side of the cylinder 123 away from the driver 121. The air inlet 111 and the air outlet 112 are connected to form a heat dissipation duct, and the driver 121, the torque amplifying device 122 and the cylinder 123 are arranged on the heat dissipation duct.

[0034] The driver 121, the torque amplifying device 122 and the cylinder 123 are arranged linearly, the air inlet 111 is located on the side of the driver 121 away from the cylinder 123, and the air outlet 112 is located on the side of the cylinder 123 away from the cylinder 123, so that the air inlet 111, the driver 121, the torque amplifying device 122, the cylinder 123 and the air outlet 112 are arranged linearly, and the external air enters the shell 110 through the air inlet 111, passes through the driver 121, the torque amplifying device 122 and the cylinder 123 in turn, and is discharged from the air outlet 112 to achieve heat dissipation for the driver 121, the torque amplifying device 122 and the cylinder 123, so that the air circulating in the heat dissipation duct formed by the air inlet 111 and the air outlet 112 can simultaneously dissipate heat for the driver 121, the torque amplifying device 122 and the cylinder 123.

[0035] Filters are provided at the air inlet 111 and the air outlet 112 respectively to prevent external debris from entering the housing 110 through the air inlet 111 and the air outlet 112. The filters are detachably mounted on the housing 110, thereby facilitating replacement and maintenance of the filters.

[0036] In a feasible embodiment of the present application, Figure 1 , Figure 2 and Figure 3As shown, one end of the output shaft of the driver 121 is connected to the torque amplifying device 122 , and the other end is provided with a cooling fan 130 , and the cooling fan 130 corresponds to the position of the air inlet 111 .

When the driver 121 moves, the cooling fan 130 can be driven to rotate when the small portable air pump 100 is inflated to accelerate the air flow rate in the shell 110. The cooling fan 130 improves the heat dissipation efficiency of the small portable air pump 100 to avoid heating of the driver 121 during the restart process.

[0038] At the same time, one end of the output shaft of the driver 121 is connected to the torque amplifier 122, and the other end of the output shaft of the driver 121 is connected to the cooling fan 130, which can improve the heat dissipation efficiency and save the working space of the small-volume portable air pump 100, making the layout of the components in the housing 110 more reasonable and compact.

[0041] For example, a first mounting groove and a second mounting groove arranged along a second direction are provided in the shell 110, the driver 121, the torque amplifying device 122 and the cylinder 123 are linearly arranged in the first mounting groove, and the battery 140 is provided in the second mounting groove, so that the layout of the components in the shell 110 is more reasonable and compact, saving the overall volume of the shell 110. It should be noted that the second direction is perpendicular to the length direction of the shell 110.

[0042] For example, Figure 4As shown, the inflatable component 120 and the battery 140 can also be arranged along the first direction, that is, the driver 121, the torque amplifying device 122, the cylinder 123 and the battery 140 are arranged in a straight line or approximately in a straight line, that is, the length direction of the battery 140 is consistent with the length direction of the shell 110, so that the layout of the components in the shell 110 is more reasonable and compact, so as to reduce the overall volume of the inflator.

[0043] In a feasible embodiment of the present application, Figure 1 , Figure 2 and Figure 3 As shown, the cylinder 123 includes a cylinder body 1231 and a piston member 1232 disposed in the cylinder body 1231 .
