[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] A type of housing for an air cooler, such as Figures 1 to 9 As shown, it includes a base 1 and a top cover 3. An integrally formed outer shell 2 is detachably connected between the base 1 and the top cover 3. The side wall of the outer shell 2 has an air inlet 4 and an air outlet 5 corresponding to the fan.

[0030] It should be noted that the outer shell 2 in the prior art is usually assembled from multiple parts. In this embodiment, the outer shell 2 is a one-piece molded structure, which eliminates the assembly steps of the outer shell 2, reduces the overall number of parts, simplifies the structure, and can effectively improve the production efficiency of the outer shell 2. Moreover, the one-piece molded structure significantly improves the structural strength and consistency of the outer shell 2, making it suitable for mass production.

[0031] The base 1 and the outer shell 2 are kept relatively fixed by a locking structure 6. In this embodiment, the locking structure 6 includes positioning buckles 61 rotatably disposed on both sides of the base 1, through holes 62 on both sides of the base 1, and positioning holes 63 on both sides of the outer shell 2. Preferably, there are four positioning buckles 61, through holes 62, and positioning holes 63.

[0032] The positioning buckle 61 has a positioning protrusion 611 and a through hole 62 for the positioning protrusion 611 to pass through. The positioning hole 63 is adapted to the positioning protrusion 611. When the positioning buckle 61 is rotated, the positioning buckle 61 drives the positioning protrusion 611 to pass through the through hole 62 and insert into the positioning hole 63, or the positioning buckle 61 drives the positioning protrusion 611 to sequentially disengage from the positioning hole 63 and the through hole 62.

[0033] When the positioning buckle 61 is rotated, causing the positioning protrusion 611 to pass through the through hole 62 and insert into the positioning hole 63, the base 1 and the outer shell 2 remain relatively fixed due to the restriction of the positioning protrusion 611. Conversely, when the positioning buckle 61 is rotated, causing the positioning protrusion 611 to successively disengage from the positioning hole 63 and the through hole 62, the relatively fixed state between the base 1 and the outer shell 2 is released due to the loss of the restriction of the positioning protrusion 611, and the base 1 and the outer shell 2 can be separated. The relative fixation or release of the relative fixation between the base 1 and the outer shell 2 can be achieved by rotating the positioning buckle 61. The disassembly and assembly operation is simple, which can effectively improve the disassembly and assembly efficiency and facilitate later maintenance.

[0034] Alternatively, the locking structure 6 can also use a pin, which is adapted to the through hole 62 and the positioning hole 63. By passing the pin through the through hole 62 and inserting it into the positioning hole 63, the base 1 and the outer shell 2 can be kept relatively fixed by the pin. Conversely, by disengaging the pin from the positioning hole 63 and the through hole 62 in sequence, the relatively fixed state of the base 1 and the outer shell 2 can be released.

[0035] Both sides of the base 1 are provided with a pivot part 7, which is integrally formed with the base 1. One end of the positioning buckle 61 has a pivot hole 8 for the pivot part 7 to pass through. The pivot part 7 and the pivot hole 8 cooperate to realize the rotation of the positioning buckle 61. The pivot part 7 and the positioning buckle 61 correspond one-to-one.

[0036] The base 1 and the outer shell 2 are clamped together with a mounting base 24 for installing the fan. By installing the fan on the mounting base 24, there is no need to set up an installation structure for the fan on the outer shell 2, which can further simplify the structure of the outer shell 2 and reduce the difficulty of manufacturing the outer shell 2.

[0037] The mounting base 24 has several mounting holes 13, and the outer shell 2 has several mounting holes 14. The mounting holes 13 and the mounting holes 14 correspond to each other. By using screws to engage the mounting holes 13 and the corresponding mounting holes 14, the base 1 and the outer shell 2 can be fixed relative to each other, and it is also convenient for disassembly and maintenance in the future.

[0038] The mounting base 24 is located inside the base 1. The base 1 has several positioning grooves 11. The lower surface of the mounting base 24 has several positioning protrusions 12. The positioning protrusions 12 are respectively inserted into the corresponding positioning grooves 11. The positioning grooves 11 limit the positioning protrusions 12. By limiting the mounting base 24 by the base 1 and limiting the positioning protrusions 10 by the positioning grooves 11, the relative stability between the mounting base 24 and the base 1 can be effectively ensured, thereby facilitating the assembly of the mounting base 24 and the base 1.

[0039] The mounting base 24 has a positioning protrusion 10, and the outer shell 2 is sleeved on the outside of the positioning protrusion 10. By restricting the outer shell 2 through the positioning protrusion 10, the relative stability between the outer shell 2 and the mounting base 24 can be effectively ensured, thereby facilitating the assembly of the mounting base 24 and the outer shell, and also facilitating the alignment of the mounting hole 13 and the mounting hole 24, thus improving the assembly efficiency of the mounting base 24 and the outer shell 2.

[0040] The base 1 has a supporting protrusion 9 inside. The upper end surface of the supporting protrusion 9 abuts against the lower surface of the mounting base 24, and the lower end surface of the outer shell 2 abuts against the upper surface of the mounting base 24, so that the base 1 and the outer shell 2 cooperate to clamp the mounting base 24.

[0041] The top cover 3 includes a cover body 31 and a cover plate 32. The cover plate 32 is placed on the cover body 31 and the two are detachably connected. Specifically, the side wall of the cover plate 32 is provided with a snap-fit ​​protrusion 22, and the side wall of the cover body 31 is provided with a connecting through hole 23. The snap-fit ​​protrusion 22 is snapped into the connecting through hole 23. Through the snap-fit ​​cooperation between the snap-fit ​​protrusion 22 and the connecting through hole 23, the relative stability of the cover body 31 and the cover plate 32 is ensured, and the cover body 31 and the cover plate 32 are also convenient for disassembly and maintenance.

[0042] Furthermore, the cover 31 has several slots 20, and the lower surface of the cover plate 32 has several inserts 21. The inserts 21 are inserted into the corresponding slots 20. By determining the relative position of the inserts 21 and the slots 20, the position of the cover plate 32 on the cover 31 can be quickly determined, and the engagement of the snap-fit ​​protrusion 22 and the connecting through hole 23 can be quickly completed, thereby effectively improving the assembly efficiency of the cover 31 and the cover plate 32.

[0043] The upper end of the outer shell 2 has a limiting protrusion 15, and the cover 31 is sleeved on the outside of the limiting protrusion 15. The cover 31 seals the upper end of the outer shell 2. The limiting protrusion 15 effectively ensures the relative stability of the outer shell 2 and the cover 31, which facilitates the assembly of the two.

[0044] Furthermore, the side wall of the limiting protrusion 15 is provided with several connecting holes 16, and the inner side wall of the cover 31 is provided with several buckles 17. The several buckles 17 are respectively engaged with the corresponding connecting holes 16. Through the engagement of the buckles 17 and the connecting holes 16, the relative stability of the cover 31 and the outer shell 2 can be effectively guaranteed.

[0045] Furthermore, the cover 31 has several mounting holes 18, and the outer shell 2 has several mounting holes 19. The mounting holes 18 and 19 correspond to each other. By using screws to engage the mounting holes 18 and 19, the cover 31 and the outer shell 2 can be fixed to each other, and the disassembly and maintenance can be facilitated later.

[0046] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
