[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] See Figures 1-9 This portable air pump includes a pump body 1, which has a storage cavity 11 for storing objects. The outer side of the pump body 1 is open at the position corresponding to the storage cavity 11 and is provided with a cover 2. The cover 2 is detachable from the pump body 1. The cover 2 is provided with a plurality of latching parts 21, where a plurality of latching parts 21 means that the number of latching parts 21 is greater than or equal to two.

[0027] The pump body 1 is provided with a buckle hole 12 corresponding to the buckle part 21. The buckle part 21 and the buckle hole 12 are engaged with each other to connect and fix the cover 2 to the pump body 1 and close the storage cavity 11. Alternatively, the buckle part 21 and the buckle hole 12 can be separated to disassemble the cover 2 from the pump body 1 and open the storage cavity 11. Since no additional locking parts are required between the cover 2 and the pump body 1, the production cost of the equipment is reduced. Moreover, the use of multiple buckle parts 21 and buckle holes 12 can greatly improve the connection strength between the cover 2 and the pump body 1 and reduce the chance of the storage cover accidentally falling off.

[0028] Furthermore, the latching part 21 extends downward and can be elastically reset. The latching part 21 is provided with a first guide slope 211, and the edge of the latching hole 12 is provided with a second guide slope 121 corresponding to the first guide slope 211. The first guide slope 211 and the second guide slope 121 are inclined from bottom to top and towards the front. The first guide slope 211 and the second guide slope 121 slide to make the latching part 21 elastically deform. The lower end of the latching part 21 is vertically offset from the periphery of the latching hole 12, so that the latching part 21 is elastically reset and engages with the latching hole 12. This makes the installation and connection of the latching part 21 and the latching hole 12 smoother and improves the user's feel.

[0029] Furthermore, the surface of the cover 2 is provided with a hollow hole 22 at a position adjacent to the buckle part 21. The buckle part 21 can elastically deform toward the side of the hollow hole 22. The hollow hole 22 can further save the material cost of the cover 2, and at the same time, it is beneficial for the buckle part 21 to undergo better elastic deformation.

[0030] Furthermore, during the installation of the cover 2 and the pump body 1, the user can determine the position of the latching part 21 by the position of the hollow hole 22, thereby enabling better alignment of the latching part 21 and the latching hole 12 and improving the installation accuracy of the cover 2 and the pump body 1.

[0031] Furthermore, the pump body 1 is provided with a recessed step 13 at the position corresponding to the buckle hole 12. The buckle hole 12 is set on the recessed step 13, and a gap is formed between the periphery of the buckle hole 12 and the periphery of the recessed step 13. The user can easily insert his / her finger into the recessed step 13 to press the buckle part 21, making it more convenient for the user to open the storage cavity 11.

[0032] Furthermore, the pump body 1 includes a front shell 14 and a bottom shell 15. The front shell 14 and the bottom shell 15 are connected and fixed by a locking mechanism and can be detached from each other. The bottom shell 15 has an electrical cavity 16, and a pumping assembly 3 for supplying air to the outside is provided in the electrical cavity 16. The receiving cavity 11 is integrally formed with the front shell 14, and the receiving cavity 11 and the electrical cavity 16 are separated from each other. The front shell 14 and the bottom shell 15 can be manufactured and processed separately, which simplifies the manufacturing process of the pump body 1.

[0033] Furthermore, a limiting edge is provided on the lower periphery of the front shell 14, which is matched with the inner wall of the bottom shell 15. A limiting platform is provided on the outer periphery of the limiting edge, which abuts against the upper periphery of the bottom shell 15, thereby improving the installation accuracy between the front shell 14 and the bottom shell 15 and improving production efficiency.

[0034] Furthermore, the outer wall of the bottom shell 15 is provided with an air inlet 151. The electrical cavity 16 and the air inlet 151 are located on the front and rear sides of the storage cavity 11, respectively. An airflow channel is formed between the bottom outer side of the storage cavity 11 and the bottom shell 15. The air inlet 151 is connected to the pumping assembly 3 through the airflow channel. The storage cavity 11 can relatively narrow the width of the airflow channel, so that the airflow speed can be increased when passing through the airflow channel, which is beneficial to improving the pumping efficiency of the pumping assembly 3.

[0035] Furthermore, a control switch assembly 4 is provided on the side of the bottom shell 15 facing away from the storage cavity 11, and the cover 2 and the storage cavity 11 do not affect the layout of the control switch assembly 4.

[0036] The control switch assembly 4 is electrically connected to the air pump assembly 3, and the user can control the working status of the air pump assembly 3 through the control switch assembly 4.

[0037] Furthermore, a limiting hook 23 is provided on the other side of the cover 2 in the front-rear direction opposite to the buckle part 21, and a limiting hole 17 corresponding to the limiting hook 23 is provided on the pump body 1. The limiting hook 23 is inserted into the limiting hole 17 to limit the fit between the cover 2 and the pump body 1. The cover 2 can swing around the limiting hook 23 to make the buckle part 21 and the buckle hole 12 engage or disengage with each other. The fit between the limiting hook 23 and the limiting hole 17 can further improve the stability of the connection structure between the cover 2 and the pump body 1, further reduce the chance of the cover 2 accidentally falling off the pump body 1, and also improve the installation accuracy of the cover 2 and the pump body 1.

[0038] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
