[0027] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0028] Figure 1 This is a schematic diagram of the overall structure of a combined air handling unit according to one embodiment of the present disclosure.

[0029] Figure 2 This is a schematic diagram of the retractable push-pull mechanism 2 of a combined air handling unit according to one embodiment of the present disclosure.

[0030] Figure 3 This is a schematic diagram of the quick-access insertion mechanism 3 and the air purification mechanism 4 of a combined air handling unit according to one embodiment of the present disclosure.

[0031] like Figures 1-3 As shown, the combined air handling unit disclosed herein may include components such as: a main body 1, a retractable push-pull mechanism 2, a quick-access insertion mechanism 3, and an air purification mechanism 4.

[0032] like Figure 1 and Figure 3 As shown, in a preferred embodiment, an air inlet pipe 11 is fixedly connected to the air inlet end on the front of the main body 1, and universal wheels with locking wrenches are fixedly installed at the four corners of the bottom of the main body 1.

[0033] Therefore, the casters can be used to move the main body 1, and after the movement is completed, the casters can be locked with a locking wrench to prevent the main body 1 from moving freely.

[0034] It should also be noted that the main body 1 is a solution already disclosed in the prior art and is not a necessary technical feature of this application. Therefore, its specific structure will not be described in detail here.

[0035] like Figure 2As shown, in the present disclosure, the storage type push-pull mechanism 2 includes two ear plates 21, both of which are fixedly arranged on the right side of the main body 1. The side close to each other of the two ear plates 21 is rotatably connected with a movable block 22 through a pin shaft. The movable block 22 is provided with an arc-shaped avoiding surface 23 on the bottom of one side of the main body 1. The top of the two movable blocks 22 is fixedly provided with a push-pull rod 24.

[0036] Thus, in order to facilitate the movement of the main body 1, the push-pull rod 24 can drive the movable block 22 to rotate until the push-pull rod 24 rotates to a horizontal state. In this process, the arc-shaped avoiding surface 23 forms an avoidance relative to the side wall of the main body 1. When the push-pull rod 24 rotates to the horizontal state, the movable block 22 is blocked relative to the inner wall of the main body 1, so that the push-pull rod 24 remains in a horizontal state for easy pushing and pulling. The push-pull rod 24 in the vertical storage state can reduce the occupation of space.

[0037] As shown, Figure 3 In a preferred embodiment, the quick plug-in mechanism 3 includes an annular insertion slot 31 provided at the end of the air inlet pipe 11. A plurality of accommodating grooves 32 are uniformly provided on the outer side of the air inlet pipe 11. The accommodating grooves 32 are in communication with the annular insertion slot 31 and the inner side of the accommodating grooves 32 is slidingly provided with a limiting steel ball 33. The bottom of the limiting steel ball 33 extends to the inner side of the annular insertion slot 31. An adjusting sleeve 34 is sleeved and arranged on the outer side of the air inlet pipe 11. The outer side of the air inlet pipe 11 and the inner side of the adjusting sleeve 34 are both provided with threads. The air inlet pipe 11 is threadedly connected with the adjusting sleeve 34. The side of the adjusting sleeve 34 is fixedly provided with a limiting ring 35. The inner side of the limiting ring 35 is provided with an annular stepped groove 36. The inner wall of the annular stepped groove 36 compresses the limiting steel ball 33. The quick plug-in mechanism 3 further includes an annular insertion plate 37 fixedly arranged on the side of the annular frame 41 and slidingly inserted into the inner side of the annular insertion slot 31. The outer side of the annular insertion plate 37 is provided with an annular limiting groove 38. The bottom of the limiting steel ball 33 extends to the inner side of the annular limiting groove 38 to form a lock.

[0038] Thus, in order to assemble the quick plug-in mechanism 3, first, the adjusting sleeve 34 is sleeved and fixed on the outer side of the air inlet pipe 11 through threads, while avoiding the limiting ring 35 from blocking the accommodating grooves 32. Then, the plurality of limiting steel balls 33 are respectively placed into the inner side of the plurality of accommodating grooves 32. Then, the adjusting sleeve 34 is rotated to drive the limiting ring 35 to block the plurality of accommodating grooves 32. At this time, the accommodating grooves 32 are located at the left end of the inner side of the annular stepped groove 36. Thus, the assembly operation is completed.

[0039] When the air purification mechanism 4 is subsequently installed and fixed, the annular plug plate 37 is inserted into the inside of the annular slot 31 until the annular frame 41 is attached to the end of the air inlet pipe 11, in the process, the limiting steel ball 33 is pushed by the annular plug plate 37 and moves out of the containing groove 32, at this time, the containing groove 32 is located at the left end inside the annular stepped groove 36, due to the blockage of the inner wall of the annular stepped groove 36, the limiting steel ball 33 cannot fall out of the containing groove 32, and when the annular frame 41 is attached to the end of the air inlet pipe 11, the limiting steel ball 33 is in line with the annular limiting groove 38, then the adjusting sleeve ring 34 is rotated, and the adjusting sleeve ring 34 drives the limiting ring 35 to move synchronously, when the limiting ring 35 moves, the plurality of limiting steel balls 33 are pushed by the inner wall of the annular stepped groove 36, and then the limiting steel balls 33 move in the containing groove 32 and enter the inside of the annular limiting groove 38, thereby realizing the locking of the annular plug plate 37, compared with the prior art, the structure of the utility model is relatively simple, can be more convenient for assembly, and the practicality is better, and in addition, when the air purification mechanism 4 is installed, it is not necessary to be accurately aligned locally, and it can be inserted directly, which is more convenient in actual use.

[0040] As shown in Figure 3 The air purification mechanism 4 comprises an annular frame 41, and an air filter screen 42 is fixedly arranged inside the annular frame 41.

[0041] Therefore, when external air is sucked into the air inlet pipe 11 by the main body 1, the air filter screen 42 filters and purifies the air to ensure the air quality.

[0042] In addition, it should be further pointed out that the contents not described in detail in the specification belong to the prior art known to those skilled in the art.

[0043] Those skilled in the art should understand that the above embodiments are only for clearly illustrating the present disclosure, and are not intended to limit the scope of the present disclosure. Based on the above disclosure, other changes or modifications can also be made by those skilled in the art, and these changes or modifications are still within the scope of the present disclosure.
