[0033] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0034] Reference Figures 1-4 This utility model provides an air pump with an automatic air extraction function, including a shell 1, which includes an upper shell 2 and a lower shell 3. The lower shell 3 has an air extraction port 31 and a detection port 32 at its front end, which are covered by a cover plate 33. The end face of the cover plate 33 has an air inlet 34. A circuit board 4 is provided inside the lower shell 3 at its rear end. The circuit board 4 has a connecting end 41, which is connected to the detection port 32 through a first flexible hose 42. An air pump 5 is provided at the middle end of the lower shell 3. The air pump 5 is connected to a stop valve 52 through a second flexible hose 51. The stop valve 52 is connected to the air extraction port 31. The air pump 5 is electrically connected to the circuit board 4. A bracket is mounted at the rear end of the lower shell 3. The battery compartment 35 has multiple connecting grooves 36 on both sides of the lower housing 3. Each connecting groove 36 contains a spring 37, which is horizontally installed on one side of the connecting groove 36. One end of the spring 37 is fitted with a locking block 38. The outer wall of the lower housing 3, opposite to the connecting groove 36, has a sliding groove 39. A sliding block 6 is provided in the sliding groove 39 and is connected to the locking block 38. The upper housing 2 and the lower housing 3 have a connecting plate 21 at the position opposite to the connecting groove 36. The connecting plate 21 and the locking block 38 have a locking groove 22 at the position opposite to the locking block 38. The surface of the lower housing 3 has a display screen 7 with a control button 71. The display screen 7 and the control button 71 are connected to the circuit board 4.

[0035] By configuring the outer casing 1 into an upper casing 2 and a lower casing 3, and then inserting the connecting plate 21 into the connecting groove 36, the connection is completed sequentially by sliding the sliding block 6 to insert the connecting plate 21 and then engaging the locking block 38 into the locking groove 22. When disassembly is needed, the sliding block 6 can be slid backward for disassembly. By sequentially installing the parts into the lower casing 3, the connections between the parts can be clearly seen after opening the upper casing 2, allowing for easy inspection without the need for sequential disassembly and inspection. The structure is relatively simple. Furthermore, by replacing the solenoid valve with the air check valve 52, no electricity is required. In case of problems, direct replacement is possible without the need for electrical connections, making replacement very convenient.

[0036] The working principle of the air pump is as follows: after the battery is powered on, double-clicking the control button 71 twice will send a command to the air pump 5 to work and draw air through the air inlet 34 and the air outlet 31. When the programmed air pressure value is reached, the air pump 5 will stop working. During this time, the air pressure sensor chip on the circuit board 4 will also work to sense whether the air pressure inside the suction cup has reached the set value. If the air pressure drops to the set danger value, it will send a command to the air pump 5 to immediately start the air pumping work until the set value is reached. The air pressure sensor chip will continue to monitor the air pressure inside the suction cup cylinder.

[0037] According to some embodiments of this utility model, optionally, a sponge sheet 7 is provided at the air inlet 34. This serves as a filter to prevent dust from entering the valve body and causing blockage.

[0038] According to some embodiments of this utility model, optionally, a cover 8 is hinged to the tail of the lower housing 3. This is for easy battery replacement after opening.

[0039] According to some embodiments of this utility model, optionally, a Type-C interface 43 is provided on one side of the circuit board 4. This interface can be used for data transmission or for charging a battery after connecting it to the circuit board 4.

[0040] According to some embodiments of this utility model, optionally, the height of the sliding block 6 will not protrude beyond the sliding groove 39. This avoids the situation where the air pump gets stuck on the inner wall of the suction cup insertion point and is damaged when it is inserted into the suction cup.

[0041] According to some embodiments of this utility model, optionally, there are no fewer than six connecting slots 36. Multiple slots are configured to maintain connectivity, preventing the upper and lower housings from quickly separating even if one becomes loose.

[0042] According to some embodiments of this utility model, optionally, the outer wall of the front end of the lower housing 3 is provided with multiple sealing rings 9. This ensures a good seal when inserted into the suction cup, preventing air leakage during operation.

[0043] According to some embodiments of this utility model, optionally, the cover plate 33 is connected to the front end of the lower housing 3 by screws. This provides good connectivity for the cover plate 33 and makes it convenient to replace the sponge sheet 7 when needed.

[0044] According to some embodiments of this utility model, optionally, the locking block 38 is made of metal, and the inner wall of the slot 22 is provided with a magnet 23. This allows the locking block 38 to be attracted when inserted, ensuring good connectivity.

[0045] It should be understood that the embodiments disclosed herein are not limited to the specific processing steps or materials disclosed herein, but should be extended to equivalent substitutions of such features as understood by those skilled in the art. It should also be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting.

Therefore, phrases or "embodiments" appearing in various places throughout the specification do not necessarily refer to the same embodiment.
