Description

Technical Field

[0001] The utility model belongs to the field of air filters, and particularly relates to an air filter air supply port structure. Background Technique

[0002] Air filters play a crucial role in our lives. They can effectively purify the air and provide us with a healthy living and working environment.

[0003] At present, the air supply ports of air filters usually have air outlets around the perimeter. Although this design can achieve a relatively wide air coverage to a certain extent, the dispersed air volume is not conducive to centralized purification of specific areas. When it is necessary to focus on purifying a certain local area in a room, the air outlet around the perimeter makes it difficult to concentrate the wind force, and the purification effect is greatly reduced. For example, in some newly decorated rooms, there may be more harmful gases released by a certain piece of furniture, and centralized air supply is required for rapid purification, but the dispersed air volume cannot meet this demand. Especially when placed in a corner or against a wall, the air outlet efficiency is severely reduced. Since the air supply port has air outlets around the perimeter, some air outlets will be blocked when against a wall or in a corner.

[0004] To solve this problem, we propose an air filter air supply port structure. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an air filter air supply port structure to solve the problems raised in the above background technique.

A closed block is provided inside the air supply port. An assembly block is provided behind the closed block. Both the closed block and the assembly block are of a quarter-circular structure;

[0007] Two installation card slots are opened behind the closed block. The assembly block is connected to the two installation card slots through installation bars;

[0008] A rotating rod is installed behind the closed block. The lower end of the rotating rod is connected to an adjustment motor. The output shaft of the adjustment motor is connected to the rotating rod.

[0009] As a preferred implementation manner, a plurality of air outlet holes are opened around the air supply port.

[0010] As a preferred implementation manner, installation blocks are respectively connected to the four perimeters above the air supply port. Fixing holes are respectively opened in the middle of each installation block.

[0012] As a preferred embodiment, a side ring is respectively arranged on the left and right sides inside the closed bottom cylinder. A guide rod is installed inside the right side ring, and the upper end of the guide rod is connected below the air supply port.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 to 3 , the present invention provides a technical solution: the structure of the air filter air supply opening 1, including: the air supply opening 1 and the air outlet hole 4. There is a closing block 5 inside the air supply opening 1, and an assembly block 41 is arranged behind the closing block 5. Both the closing block 5 and the assembly block 41 are of a quarter-circular structure;

[0026] Two mounting slots 10 are opened behind the closing block 5, and the assembly block 41 is connected to the two mounting slots 10 through the mounting strip 7;

[0027] A rotating rod 6 is installed behind the closing block 5, and the lower end of the rotating rod 6 is connected to an adjusting motor 11, and the output shaft of the adjusting motor 11 is connected to the rotating rod 6.

[0028] A plurality of air outlet holes 4 are opened around the air supply opening 1.

[0029] Around the upper part of the air supply opening 1, a mounting block 2 is respectively connected, and a fixing hole 3 is respectively opened in the middle of each mounting block 2.

[0030] A closed bottom cylinder 8 is installed below the air supply opening 1, and a support base 9 is connected below the closed bottom cylinder 8.

[0031] On the left and right sides inside the closed bottom cylinder 8, a side ring 13 is respectively arranged, and a guide rod is installed inside the right side ring 13, and the upper end of the guide rod is connected to the lower part of the air supply opening 1.

[0032] The two side rings 13 are respectively connected to the adjusting motor 11 through the side connecting rods 12.

[0033] The inner wall of the left side ring 13 is provided with internal threads, and a threaded rod 14 is connected inside the left side ring 13 through threads.

[0034] A servo motor 15 is installed inside the support base 9, and the output shaft of the servo motor 15 is connected to the threaded rod 14.

[0035] Please refer to Figures 1 to 3 , as the first embodiment of the present utility model: In actual use, the mounting block 2 can be connected to the air filter by bolts passing through the fixing holes 3 to complete the installation of the air supply port 1. When it is necessary to adjust to the concentrated air outlet state on one side, the adjusting motor 11 can be driven to drive the rotating rod 6 to rotate. The rotating rod 6 can drive the assembling block 41 to rotate through the closing block 5, so that the closing block 5 and the assembling block 41 rotate to block the air outlet holes 4 on the other side, thereby enabling concentrated air outlet through the opposite side and improving the air outlet efficiency;

[0036] And if the shielding range of the closing block 5 and the assembling block 41 is large, the assembling block 41 can be lifted upward to disconnect the mounting strip 7 from the mounting slot 10, and thus the disassembly of the assembling block 41 can be quickly completed. After disassembly, the air outlet can be blocked by the closing block 5. The shielding range of the closing block 5 is small, and then a larger range of concentrated air outlet can be achieved, which can be flexibly selected according to actual use requirements.

[0037] Please refer to Figures 1 to 3 , as the second embodiment of the present utility model: When it is not necessary to block the air outlet holes 4 and four-sided air outlet is required, the servo motor 15 is driven to reverse the threaded rod 14. The threaded rod 14 rotates within the left side ring 13, thereby being able to drive the left side ring 13 to descend. Furthermore, the adjusting motor 11 is driven to descend through the side connecting rod 12. The adjusting motor 11 then drives the closing block 5 and the assembling block 41 to descend through the rotating rod 6, so that they no longer block the air outlet holes 4, and thus four-sided air outlet is achieved. It can be flexibly selected according to actual use scenarios. While descending, the adjusting motor 11 drives the right side ring 13 to descend along the guide rod path through the right side connecting rod 12, improving the stability of the descent of the closing block 5.

[0038] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
