[0027] Reference Figure 1 The handheld electric pumping device includes a main unit 7 and a detachable battery assembly 1.

[0028] Reference Figure 2 The top of the main body 7 is provided with a storage cavity 11, the front edge of the storage cavity 11 is provided with an axis hole, the mouth of the storage cavity 11 is provided with a cavity cover 13, the front edge of the cavity cover 13 is provided with a hinge shaft 131, the hinge shaft 131 is connected to the axis hole of the front edge of the storage cavity 11, and the cavity cover 13 is hinged to the front edge of the storage cavity 11. Figure 2 、 Figure 4 and Figure 5 A lock latch is provided between the rear edge of the cavity cover 13 and the storage cavity 11. Specifically, the lock latch is a push-type latch comprising a latch body 17 and a locking tongue 18. The locking tongue 18 is provided on the surface of the cavity cover 13 facing the storage cavity 11, near the rear edge of the cavity cover 13, while the latch body 17 is provided at the rear edge of the storage cavity 11. When the cavity cover 13 is in the locked state, pressing the rear edge of the cavity cover 13 disengages the locking tongue 18 from the latch body 17, placing the cavity cover 13 in the unlocked state. When the cavity cover 13 is in the unlocked state, pressing the rear edge of the cavity cover 13 engages the locking tongue 18 with the latch body 17, placing the cavity cover 13 in the locked state.

[0029] In this embodiment, by setting a storage cavity 11 and a cavity cover 13 on the top of the main unit 7, the connectors and the like of the electric pumping device can be stored in the storage cavity 11 on the main unit 7, thereby preventing the connectors and the like from being lost or forgotten.

[0030] The cavity cover 13 is connected to the main unit 7 in a hinged manner and combined with a push-type lock, which not only makes it easy to open and close the cavity cover 13 and facilitates quick access to the matching connectors, but also prevents the lock from being exposed when the cavity cover 13 is locked, making the appearance of the main unit 7 neater.

[0031] It should be noted that the use of a push-type lock is only a preferred embodiment. The lock between the storage cavity 11 and the cavity cover 13 can also be a rotary lock. Specifically, a vertical axis is provided on the main unit 7 near the rear edge of the storage cavity 11, and the vertical axis is connected to a horizontal bolt. By changing the position of the horizontal bolt around the vertical axis, the cavity cover 13 is locked and unlocked. The lock between the storage cavity 11 and the cavity cover 13 can also be a latch lock. Specifically, a latch that can slide in the front-to-back direction is provided on the main unit 7 near the rear edge of the storage cavity 11. By changing the position of the latch in the front-to-back direction, the cavity cover 13 is locked and unlocked.

[0032] Preferably, a torsion spring is provided on the hinge shaft 131 of the cavity cover 13. When the cavity cover 13 is closed, the torsion spring is in an energy storage state. In this way, when the cavity cover 13 is unlocked, the torsion spring releases energy, causing the cavity cover 13 to automatically open, thereby making it more convenient to use.

[0033] Reference Figure 2 The storage cavity 11 is provided with a storage rack 12. When in use, the connectors of the electric pumping device are placed on the storage rack 12. The storage rack 12 forms a limit function for the connectors, etc., which can prevent the connectors, etc. from moving and colliding in the storage cavity 11.

[0034] Reference Figure 3 The storage rack 12 comprises a base plate with a valve needle receiving slot 15, a tapered connector receiving slot 14, and a T-connector receiving slot 16. The base plate's outer contour matches the outer contour of the storage chamber 11. In this embodiment, the storage rack 12 is constructed from a plate body with receiving slots. Simply forming slots that match the connectors on the plate body facilitates manufacturing. The integrated valve needle receiving slot 15, tapered connector receiving slot 14, and T-connector receiving slot 16 allow the rack 12 to store two connectors and a valve needle.

[0035] The base of the rack 12 is preferably a foam board or a sponge board. Foam boards and sponge boards are light, low-cost, and have good elasticity. The rack 12 made of foam boards or sponge boards is not only light, but also can use the inherent elasticity of the foam boards or sponge boards to fix accessories, without the need for a special fixing structure.

[0036] Reference Figure 1 The bottom end of the host 7 includes a handheld portion 3, and the battery assembly 1 is detachably connected to the handheld portion 3. When the power of the battery assembly 3 is exhausted, the battery assembly 3 can be removed and replaced with a spare battery assembly to continue working.

[0038] Combine Figure 1 and Figure 6 The bottom end of the handheld portion 3 is provided with a battery connecting seat 2, and the bottom end of the battery connecting seat 2 is provided with a receiving cavity 20, and the two opposite sides of the receiving cavity 20 are provided with connecting grooves 19. Correspondingly, the two sides of the battery assembly 1 are provided with connecting protrusions 22 and positioning protrusions 21. When connecting, align the connecting protrusion 22 of the battery assembly 1 with the front end of the connecting groove 19 on the battery connecting seat 2, push the battery assembly 1 backward, insert the connecting protrusion 22 into the connecting groove 19, and place the top end of the battery assembly 1 into the receiving cavity 20 at the bottom end of the battery connecting seat 2. The positioning protrusion 21 abuts against the front end of the battery connecting seat 2, thus completing the connection between the battery assembly 1 and the handheld portion 3. The state after connection is as follows: Figure 1 In this embodiment, the battery assembly 1 is assembled in a sliding manner.

[0039] Optionally, the battery assembly 1 can also be assembled by snap-fitting. Specifically, a battery accommodating cavity is provided at the bottom end of the handheld portion 3, and a snap-fitting structure is provided at the edge of the mouth of the battery accommodating cavity. The battery assembly 1 is installed in the battery accommodating cavity and is retained in the battery accommodating cavity by the snap-fitting structure.

[0040] In this embodiment, the battery assembly 1 is disposed on the handheld portion 3 so that the center of gravity of the handheld electric pump is close to the handheld portion 3 , which is convenient for handheld operation.

[0041] Reference Figure 1 The front end of the main unit 7 is provided with an air supply pipe 9, the front end of the air supply pipe 9 is provided with an air supply joint 10, and the rear end of the air supply pipe 9 extends into the main unit 7 and is connected to the air outlet of the air pump.

[0042] The rear end of the host 7 is provided with a control panel 6, which is provided with an air pressure setting key 5 and an air pump start key 4. The air pressure setting key 5 and the air pump start key 4 are connected to the air pump control circuit 24 in the host 7 (see FIG. Figure 7 ) are electrically connected to form the air pump 25 (see Figure 7 ) automatic control circuit.

[0043] The handheld portion 3 is provided with a trigger 8, and a control switch 23 is provided inside the handheld portion 3 corresponding to the trigger 3. The control switch 23 is connected to the air pump control circuit 24 (see Figure 7) are electrically connected to form the air pump 25 (see Figure 7 ) manual control circuit.

[0044] This embodiment includes an automatic air pump control circuit and a manual air pump control circuit, enabling both automatic and manual inflation. During automatic inflation, the target air pressure is preset using the air pressure setting key 5, and the air pump 25 is then activated using the air pump start key 4. When the preset target air pressure is reached, the automatic air pump control circuit controls the air pump to stop. During manual inflation, the trigger 8 is pulled, triggering the control switch 23. The control switch 23 outputs a start signal, activating the air pump 25. When the trigger 8 is released, the control switch 23 outputs a stop signal, deactivating the air pump 25.
