[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] The embodiment of the present application provides a portable inflation and deflation pump, which can solve the problem in the related art that it is difficult to control the tire pressure when deflating the tire.

[0031] See also Figures 1 to 3As shown, an embodiment of the present application provides a portable air charging and discharging pump, including a shell 1, a gas pipeline 2, a control unit and an operation panel 8; the gas pipeline 2 includes a first pipeline 21 located in the shell 1 and a second pipeline 22 connected to the first pipeline 21 and located outside the shell 1, and the first pipeline 21 is connected to a deflation valve 3 and a pressure sensor 4; the deflation valve 3 and the pressure sensor 4 are both connected to the control unit, and the control unit is used to automatically close the deflation valve 3; the operation panel 8 is connected to the control unit, and an adjustment button 81 is provided on the operation panel 8 for presetting the air pressure value.

[0032] In actual use, the tire can be connected to the inflation and deflation pump, and then the deflation valve 3 is used to deflate the tire through the second pipe 22 and the first pipe 21 in sequence. At this time, since the pressure sensor 4 is connected to the first pipe 21 of the inflation and deflation pump, the deflation valve 3 is also connected to the first pipe 21, and the deflation valve 3 and the pressure sensor 4 are both connected to the control unit, the pressure sensor 4 can transmit the monitored data information to the control unit, and the control unit controls the deflation valve 3 to close. In actual operation, the operation panel 8 is connected to the control unit, and the adjustment button 81 of the operation panel 8 can be used to preset the air pressure value, and then the inflation and deflation pump is started. When the deflation valve 3 of the inflation and deflation pump deflates to the preset air pressure value, the pressure sensor 4 can transmit the monitored data information to the control unit, and the control unit controls the deflation valve 3 to close, thereby avoiding the situation that when the tire is manually deflated, the tire is deflated more or less due to inadequate judgment of the tire pressure.

[0033] In some optional embodiments, such as Figure 3 and Figure 5 As shown, the pump core 7 for inflating is also included, and the pump core 7 is connected to the pressure sensor 4 and the control unit. In actual use, the pump core 7 is used to inflate the tire, and the pump core 7 is connected to the pressure sensor 4 and the control unit. The tire pressure to which the tire needs to be inflated can be preset according to the actual situation. Specifically, the air pressure value is preset by using the adjustment button 81 of the operation panel 8, and then the pump core 7 is inflated. When the pressure sensor 4 detects that the air pressure reaches the preset value, the data information is fed back to the control unit, and the control unit controls the pump core 7 to close and stop inflating.

[0034] When the vehicle is driving normally, the tire needs to be inflated to ensure that it has sufficient tire pressure. When the vehicle is climbing a slope on a slippery road in rainy and snowy weather, it is often necessary to temporarily deflate the tire to reduce the tire pressure. The inflation and deflation pump of the present application can use the adjustment button 81 of the operation panel 8 to preset the air pressure value that needs to be adjusted, and then automatically stop the inflation or deflation operation of the pump body in time through the control unit, so as to achieve quantitative inflation or deflation of the tire, and can standardize the inflation or deflation amount, solving the problem that the amount of deflation or inflation of the tire is difficult to grasp and control due to inadequate judgment of the tire pressure. In actual use, the control unit is integrated on a circuit board and arranged in the housing 1.

[0035] In some optional embodiments, such as Figure 3 and Figure 4 As shown, the air release valve 3 is in an "L"-shaped structure, and an opening 31 for discharging gas is provided on the air release valve 3. One end of the air release valve 3 is fixedly connected to the first pipeline 21, and the air release valve 3 is in an "L"-shaped structure, which is convenient for reducing the occupied space, thereby optimizing the layout space in the housing 1. The air release valve 3 is provided with an opening 31 for discharging gas. A plurality of openings 31 can be provided according to actual needs, and the size can be set according to actual conditions to ensure that the air release valve 3 can be smoothly deflated with the help of the opening 31.

[0036] In some optional embodiments, such as Figure 1 and Figure 2 As shown, a joint 221 for connecting to a wheel is provided at one end of the second pipe 22, and the joint 221 is butted against the wheel so that the entire pump body is connected to the wheel.

[0037] In some optional embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the pump core 7 and the deflation valve 3 are connected to a motor 5 for providing power, and the motor 5 is connected to a battery system 6. The motor 5 provides power for the pump core 7 and the deflation valve 3, and the battery system 6 supplies power to the motor 5.

[0038] In some optional embodiments, such as Figure 1 and Figure 2 As shown, the housing 1 is in a "T"-shaped structure, including an upper housing 11 in a rectangular parallelepiped structure and a lower housing 12 in a cylindrical structure, and the lower housing 12 is perpendicular to the upper housing 11. All parts are integrated in the housing 1 in a "T"-shaped structure. The "T"-shaped structure makes the housing 1 similar to a hammer-shaped structure, which is convenient to carry and hold. In some actual use situations, an inclined surface section 111 for transition is provided between two adjacent surfaces of the upper housing 11. The provision of the inclined surface section 111 can reduce the occupied space of the entire upper housing 11 and make the transition between two adjacent surfaces of the upper housing 11 smoother.

[0039] Specifically, Figure 3 and Figure 5 As shown, the motor 5 and the battery system 6 are both arranged in the lower housing 12, and the pump core 7, the first pipe 21, the air release valve 3 and the pressure sensor 4 are all arranged in the upper housing 11. In actual use, the motor 5 and the battery system 6 are both located in the lower housing 12, and the motor 5 and the battery system 6 are arranged in the vertical direction. The surface of the lower housing 12 can be set to a cylindrical structure or a rectangular parallelepiped structure to reduce the occupied space and facilitate carrying and holding.

[0040] In some optional embodiments, such as Figure 3 and Figure 4 As shown, a connector 32 for connecting the first pipe 21 is provided on one side of the air release valve 3, and the connector 32 includes a plurality of hollow truncated cone-shaped connecting sections 321 connected in sequence, and the bottom area of ​​each connecting section 321 close to the first pipe 21 is smaller than the bottom area of ​​the end away from the first pipe 21. The provision of the connector 32 can ensure a good fixed connection between the air release valve 3 and the first pipe 21, and improve the airtightness of the overall structure.

[0041] Specifically, the connecting piece 32 includes a plurality of hollow truncated cone-shaped connecting sections 321 connected in sequence, and the bottom area of ​​each connecting section 321 close to the end of the first pipe 21 is smaller than the bottom area of ​​the end away from the first pipe 21. A protruding structure matching the connecting piece 32 is provided on the inner wall of the first pipe 21. The setting of the connecting section 321 ensures that when the connecting piece 32 is inserted into the first pipe 21 for fixation, the connecting section 321 contacts the inner wall of the first pipe 21, preventing the connecting piece 32 from easily falling out of the first pipe 21, thereby enhancing the tightness and reliability of the structural connection and ensuring the airtightness of the overall structure.

[0042] In actual use, the above-mentioned connecting pieces 32 may also be provided at both ends of the pressure sensor 4 to improve the airtightness of the connection between the first pipeline 21 and the pressure sensor 4 .

[0043] In some use cases, the portable air pump of the present application can integrate a voice control module and a Bluetooth communication unit. The voice control module can facilitate the user to control the pump body, and the Bluetooth communication unit can connect the pump body to a mobile phone. When encountering adverse conditions such as rain and snow, the user can connect the pump body via Bluetooth and remotely control the pump body to improve the convenience of operation. In addition, the pump body can be equipped with a large-capacity rechargeable battery and a dual redundant power supply through an external vehicle power supply through a power interface to ensure that the range of the pump body power and air pressure values ​​is large, so that the pump body can be applied to different sizes of vehicles including passenger cars, off-road vehicles, commercial vehicles, etc.
