[0034] The present application embodiment discloses an air pump housing that is easy to install. Figure 1An air pump housing that is easy to install includes a pump housing 1, an end cover 2 and a locking assembly 3, wherein the end cover 2 is connected and fixed to the end of the pump housing 1 through the locking assembly 3.

[0035] Reference Figure 1 , Figure 2 and Figure 3 , the end at which the pump casing 1 is connected and fixed to the end cover 2 is the front end of the pump casing 1. In order to improve the noise reduction performance of the air pump housing, a noise reduction layer 11 is placed inside the pump casing 1. The noise reduction layer 11 is composed of a plate containing sound-absorbing material. An insertion portion 21 is integrally formed at one end at which the end cover 2 is connected and fixed to the pump casing 1, that is, at the rear end of the end cover 2. The insertion portion 21 is used to insert into the interior of the pump casing 1. An air intake pipe 22 is provided at the end of the end cover 2 that is away from the insertion portion 21. The air intake pipe 22 penetrates to the rear end of the insertion portion 21.

[0036] Reference Figure 2 , Figure 3 and Figure 4 In order to improve the sealing performance when the end cover 2 is fixed to the pump casing 1, a first sealing groove 12 is opened at the front end of the pump casing 1, and a second sealing groove 23 is opened at the rear end where the end cover 2 abuts against the pump casing 1. The first sealing groove 12 and the second sealing groove 23 are aligned to form a complete sealing cavity, and a sealing ring 121 is placed in this complete sealing cavity.

[0037] Reference Figure 2 , Figure 3 and Figure 4 The locking assembly 3 includes a locking block 31, a threaded ring groove 32, a plurality of equally spaced latches 33 and a hook column 34. The locking block 31 is welded to the inner wall of the pump casing 1 near the front end. In order to prevent the locking block 31 from being blocked by the noise reduction layer 11, an avoidance hole 111 is opened at the position where the noise reduction layer 11 is aligned with the locking block 31, and the locking block 31 can pass through the noise reduction layer 11 through the avoidance hole 111.

[0038] Reference Figure 3 and Figure 4 The threaded groove 32 is formed on the outer wall of the insertion portion 21, and the locking block 31 is used to slide in the threaded groove 32. In the present embodiment, according to the size of the insertion portion 21 and in order to facilitate the installation and removal of the end cover 2 and the pump casing 1, it is preferred to form a circle of threaded groove 32 on the insertion portion 21. Therefore, when fixing the end cover 2 and the pump casing 1, it is only necessary to rotate the end cover 2 one circle. When the end cover 2 is disconnected from the pump casing 1, it is only necessary to rotate the end cover 2 one circle in the opposite direction.

[0039] Reference Figure 3 , Figure 4 and Figure 5, an entry end 321 and a locking end 322 are respectively provided at both ends of the threaded groove 32, the entry end 321 is located at the end of the insertion portion 21 away from the end cover 2, and the locking end 322 is located at the end of the insertion portion 21 close to the end cover 2, and an entry channel 3211 is provided at the end of the entry end 321 away from the end connected to the threaded groove 32, and the entry channel 3211 extends toward the rear end of the insertion portion 21 and penetrates the rear end of the insertion portion 21, so that the locking block 31 slides into the entry end 321 through the entry channel 3211, and the locking block 31 can slide in the threaded groove 32;

[0040] Reference Figure 4 and Figure 5 A locking channel 3221 is provided at the end of the locking end 322 that is away from the threaded ring groove 32, and the locking channel 3221 extends toward the front end of the insertion portion 21, and a locking groove 3222 is provided at the end of the locking channel 3221 that is away from the locking end 322, and the width of the locking channel 3221 is smaller than the width of the locking groove 3222. When the end cover 2 is rotated one circle, the locking block 31 slides to the locking end 322 of the threaded ring groove 32. Since the width of the locking channel 3221 is smaller than the width of the locking groove 3222, it is necessary to apply a certain pressure to the end cover 2 so that the locking block 31 enters the locking channel 3221 and then enters the locking groove 3222 to be locked, that is, the end cover 2 is fixed to the front end of the pump casing 1.

[0041] Reference Figure 1 and Figure 4 Several equidistantly distributed latches 33 are welded on the outer wall of the pump casing 1 near the front end. In the present embodiment, according to the size of the pump casing 1 and to facilitate the installation and disassembly of the air pump housing, four latches 33 are preferably arranged on the outer wall of the pump casing 1 near the front end. The latches 33 include a hook portion 331 and a pull portion 332. The hook portion 331 is located on the outer wall of the pump casing 1 near the end cover 2, and the pull portion 332 is arranged away from the hook portion 331.

[0042] Reference Figure 3 and Figure 4 The hook column 34 is arranged on the outer wall of the end cover 2 near the rear end. Since the hook column 34 is used in conjunction with the buckle 33, in the present embodiment, four equidistantly distributed hook columns 34 are welded on the outer wall of the end cover 2 near the rear end. The hook column 34 is used to engage with the hook portion 331. Therefore, when the hook portion 331 is engaged with the hook column 34, it is only necessary to pull the pull portion 332 in the direction away from the hook portion 331 to further improve the stability of the connection between the end cover 2 and the pump casing 1. When the end cover 2 needs to be removed from the upper end of the pump casing 1, it is only necessary to pull the pull portion 332 in the direction of the hook portion 331 to remove the hook portion 331 from the hook column 34.

[0043] The implementation principle of an air pump housing that is easy to install in the embodiment of the present application is as follows: after aligning the entry channel 3211 with the locking block 31, the insertion portion 21 is inserted into the interior of the pump housing 1. While the insertion portion 21 is inserted into the interior of the pump housing 1, the locking block 31 moves in the entry channel 3211. When the locking block 31 moves to the entry end 321 through the entry channel 3211, the insertion portion 21 cannot continue to extend into the pump housing 1 in the direction toward the rear end. At this time, the end cover 2 is rotated in one direction to rotate the insertion portion 21 into the pump housing 1. At the same time, the locking block 31 is rotated along the threaded ring groove 32 to the locking end 322. When the locking block 31 moves After the locking end 322 is moved into the locking end, the end cover 2 is not easy to rotate in this direction, and a certain pressure is applied to the end cover 2 toward the pump casing 1, so that the locking block 31 passes through the locking channel 3221 and enters the locking groove 3222 to lock with the locking groove 3222, completing the fixation of the pump casing 1 and the end cover 2. Finally, the hook portion 331 is buckled on the hook column 34, and the pull portion 332 is pulled in the direction away from the hook portion 331 to fix the hook portion 331 on the hook column 34. Repeat this action four times, which is beneficial to further improve the stability of the pump casing 1 and the end cover 2 when they are fixed, and is beneficial to facilitate the maintenance personnel to install the air pump housing;

[0044] When it is necessary to inspect or replace parts of the air pump, the lever portion 332 is pushed in the direction of the hook portion 331 to loosen the hook portion 331 and the hook column 34. Repeat this action four times to disconnect the hook portion 331 and the hook column 34, pull the intake pipe 22, so that the locking block 31 disengages from the locking groove 3222 and moves into the threaded ring groove 32 through the locking channel 3221. The end cover 2 can be rotated in another direction to rotate the insertion portion 21 out of the pump casing 1. When the locking block 31 moves to the entry end 321, the end cover 2 is not easy to rotate in this direction, and the end cover 2 can be pulled out in the direction away from the pump casing 1. At this time, the locking block 31 disengages from the threaded ring groove 32 through the entry channel 3211, and the disassembly of the pump casing 1 and the end cover 2 is completed.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
