[0032] In view of the technical problems described in the background art, such as Figure 1-14 As shown, a novel air pump is provided, comprising: a housing 1, wherein the housing 1 has an installation space inside; a latch 2 is provided on the left and right sides of the upper end face of the housing 1, and a latching strip 3 extending radially inside the housing 1 is provided on both sides of the latch 2, the latching strip 3 having a gap on both sides; and a handle 4, which is installed on the upper end face of the housing 1, and a hook 5 is provided at both ends of the handle 4, the two ends of the handle 4 being fastened to the latch 2 by the hook 5.

[0033] In the above, the housing 1 is the outer shell of the new air pump. The housing 1 has an installation space and is equipped with components such as a motor and a fan. The motor drives the fan to achieve air inflation. Since this is existing technology and not an improvement of this technical solution, it will not be described in detail.

[0034] Two symmetrical bayonet slots 2 are arranged on the upper left and right sides of the casing 1. Each bayonet slot 2 has radially extending retaining strips 3 on both sides, with gaps between the retaining strips 3 to accommodate the hooks 5 of the handle 4. The handle 4 is designed with hooks 5 at its end face, which are arrow-shaped. During assembly, the hooks 5 at both ends of the handle 4 are inserted into the bayonet slots 2. The retaining strips 3 are opened by the action of the hooks 5. When the hooks 5 are pressed into place, the retaining strips 3 are locked onto the hooks 5, completing the assembly operation.

[0035] In the above technical solution, the handle 4 can be quickly installed and firmly fixed by the elastic snap-fit ​​structure between the hook 5 and the bayonet 2. The installation is convenient, saves installation parts, and reduces costs.

[0036] like Figure 7-10 As shown, the upper surface of the housing 1 has at least one inflation position 6; the inflation position 6 includes a through hole 7 on the upper surface of the housing 1, a mounting bracket 8 located below the through hole 7 and connected to the inner wall of the housing 1, a switch 9 on the mounting bracket 8, and an air nozzle 10 installed at the through hole 7; the air nozzle 10 has a hollow structure, and a contact bone 11 is provided at the lower part of the air nozzle 10, the contact bone 11 extending to the position of the switch 9; wherein, when the air nozzle 10 is pressed from the outside, the contact bone 11 triggers the switch 9 to connect the circuit and drive the motor to blow air.

[0037] The above describes an integrated inflation position 6. The number of inflation positions 6 can be selected according to actual usage requirements, which will not be elaborated further. To facilitate the installation of the switch 9, a mounting bracket 8 is designed below the through hole 7. The mounting bracket 8 is integral with the housing 1 and is used to install the switch 9, which can be a micro switch. The air nozzle 10 is installed at the through hole 7, and the lower part of the air nozzle 10 extends to the contact point 11 of the micro switch 9.

[0038] When in use, pressing the air nozzle 10 will trigger the switch 9 by touching the bone position 11, directly driving the motor to blow air. Releasing the air nozzle 10 will turn off the switch 9 and the motor will shut off. It is easy to use.

[0039] refer to Figure 11-12As shown, the housing 1 includes an upper shell 12 and a lower shell 13 disposed below the upper shell 12; the upper shell 12 has an upper rim 14 surrounding the upper shell 12, and a first connecting post 15 is provided at each of the four corners of the inner wall of the upper shell 12, the top of the first connecting post 15 protruding from the upper rim 14; the lower shell 13 has a lower rim 16 surrounding the lower shell 13, and a second connecting post 17 is provided at each of the four corners of the inner wall of the lower shell 13 to cooperate with the first connecting post 15, the top of the second connecting post 17 being lower than the lower rim 16, and the top of the second connecting post 17 having a recessed slot 18; wherein, when the upper shell 12 and the lower shell 13 are connected, the top of the first connecting post 15 is placed in the slot 18 of the second connecting post 17.

[0040] In a preferred embodiment, the housing 1 includes an upper shell 12 and a lower shell 13, which are connected by four-corner alignment. Specifically, the top of the first connecting post 15 of the upper shell 12 is a tapered guide head, and the slot 18 of the second connecting post 17 of the lower shell 13 is a matching tapered groove, which guides the initial alignment. During the locking stage, screws are passed through the through holes 7 of the second connecting post 17 and the threaded holes of the first connecting post 15 in sequence and tightened, so that the upper edge 14 and the lower edge 16 are completely fitted together. The slot 18 is used for positioning to ensure assembly accuracy, reduce assembly difficulty, and enhance the overall stability of the housing.

[0041] like Figure 13-14 The lower end of the air nozzle 10 is provided with a buckle 19 on its circumferential edge; when the air nozzle 10 is assembled into the through hole 7, the buckle 19 abuts against the circumferential edge of the through hole 7.

[0042] To simplify the installation of the air nozzle 10 and improve its stability, a buckle 19 is provided at the lower end of the air nozzle 10. When installing the air nozzle, if the lower end of the air nozzle 10 is placed inside the through hole 7 and moves downward, the buckle 19 will push out from the side and abut against the lower edge of the through hole 7 when the lower end of the air nozzle 10 moves to the lower edge of the through hole 7.

[0043] like Figure 9-10 As shown, the air nozzle 10 has a radially protruding step 20 on its circumferential surface; the step 20 is used to seal the edge gap of the through hole 7 when the air nozzle 10 is pressed by external force.

[0044] In actual use, when the air nozzle 10 is pressed down to start the motor, air will come out from the through hole 7. There is a gap at the edge of the through hole 7, which causes hot air to blow onto the hand. By adding a step 20 around the outer periphery of the air nozzle 10, it can fit against the end face of the housing 1, and the hot air will not blow onto the hand.

[0045] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
