Detailed implementation manners

[0024] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

The filter and dust removal device for a fan provided by the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] As Figures 1 to 4 shown, the filter and dust removal device for a fan provided in this embodiment mainly includes a mounting sleeve 1, an inner sleeve 2, a dust-proof net 4, a rotating sleeve 5, and a discharge cylinder 9.

[0027] Specifically, the installation sleeve 1 is fixedly installed with the outer frame at the rear end of the fan, so that the device is connected to the fan. An inner sleeve 2 is arranged in the inner cavity of the installation sleeve 1. Through the arrangement of the inner sleeve 2, it is convenient to install the driving motor of the fan in the inner sleeve 2, saving installation space. A dust-proof net 4 is fixedly installed between the inner sleeve 2 and the installation sleeve 1. Through the arrangement of the dust-proof net 4, when the fan is in use, most of the dust and particulate matter are blocked on the outer wall of the dust-proof net 4. A rotating sleeve 5 is sleeved on the outer wall of the inner sleeve 2. The rotating sleeve 5 is rotationally matched with the inner sleeve 2, that is, the inner sleeve 2 is fixed and the rotating sleeve 5 can rotate along the outer wall of the inner sleeve 2. A first gear 18 is evenly arranged on the outer wall of the rotating sleeve 5, and a second gear 17 is evenly arranged on the inner wall of the installation sleeve 1. A discharge cylinder 9 is arranged between the rotating sleeve 5 and the installation sleeve 1. A third gear 16 is evenly arranged on the front outer wall of the discharge cylinder 9. The third gear 16 meshes with the first gear 18 and the second gear 17 respectively. Through the design of the above gear structure, when the rotating sleeve 5 is rotated, through the meshing of the first gear 18 and the third gear 16 and the meshing of the third gear 16 and the second gear 17, the discharge cylinder 9 can rotate circularly in the track between the installation sleeve 1 and the inner sleeve 2, and at the same time, the discharge cylinder 9 itself can rotate. A plurality of groups of dust-cleaning sponges 15 are fixedly installed on one end outer wall of the discharge cylinder 9. The dust-cleaning sponges 15 rotate circularly and rotate by themselves in the track between the installation sleeve 1 and the inner sleeve 2 along with the discharge cylinder 9. In this way, the friction between the dust-cleaning sponges 15 and the dust-proof net 4 can be realized, and the dust on the outer wall of the dust-proof net 4 can be wiped off. Rectangular dust-collecting grooves 14 are respectively opened at both ends of the dust-cleaning sponges 15. The dust wiped by the dust-cleaning sponges 15 enters the rectangular dust-collecting grooves 14 along the outer wall of the dust-cleaning sponges 15, that is, the rectangular dust-collecting grooves 14 are used to collect the dust wiped by the dust-cleaning sponges 15. A baffle block 13 is fixedly installed in the inner cavity of the discharge cylinder 9. The baffle block 13 is located at the center position behind the rectangular dust-collecting groove 14. Through the rotation of the discharge cylinder 9, the dust enters the rear end of the discharge cylinder 9 from the periphery of the baffle block 13, and the baffle block 13 can prevent the dust from flowing back. A threaded port 21 is opened at the tail end of the discharge cylinder 9. A discharge valve port 22 is in threaded fit with the threaded port 21. When it is necessary to pour the dust in the discharge cylinder 9, the discharge cylinder 9 is taken out along the tooth gap, and the discharge valve port 22 of the discharge cylinder 9 is taken out to clean the dust in the discharge cylinder 9.

[0028] The working process is as follows: When dust needs to be cleaned, rotate the rotating sleeve 5. Through the meshing of the first gear 18 and the third gear 16 and the meshing of the third gear 16 and the second gear 17, the discharge cylinder 9 can rotate circularly within the track between the mounting sleeve 1 and the inner sleeve 2, and at the same time, it can rotate itself. Through the friction between the dust cleaning sponge 15 and the dust-proof net 4, the dust on the outer wall of the dust-proof net 4 is wiped off and enters the rectangular dust collection groove 14 along the outer wall of the dust cleaning sponge 15. Through the self-rotation of the discharge cylinder 9, the dust enters the rear end from around the baffle block 13, and the dust is cleaned and collected. When the dust in the discharge cylinder 9 needs to be emptied, the discharge cylinder 9 is taken out along the tooth gap, and the discharge valve port 22 is taken out to clean the dust in the discharge cylinder 9. After cleaning, it is reinstalled.

[0029] As a preferred implementation manner of the embodiment of the present invention, the discharge valve port 22 includes: a tail end plate 12, a threaded connection block 11 and a knob 19. The tail end plate 12 is fixedly connected to the threaded connection block 11 and the knob 19, and the threaded connection block 11 is threadedly connected to the threaded port 21. The setting of the threaded connection block 11 makes it convenient for the discharge valve port 22 to be screwed to the threaded port 21 of the discharge cylinder 9. When taking out the discharge valve port 22, the knob 19 can be manually rotated, making it convenient and labor-saving to take out the discharge valve port 22. Further, as a preferred implementation manner of the embodiment of the present invention, the outer wall of the knob 19 is uniformly provided with anti-slip teeth, making it labor-saving when manually rotating the knob 19.

[0030] As a preferred implementation manner of the embodiment of the present invention, an arc-shaped baffle ring 10 is provided behind the baffle block 13, and the arc-shaped baffle ring 10 is located at the edge position of the inner wall of the discharge cylinder 9. Although there is the baffle block 13 to block the dust, there will still be dust backflow through the gaps around the baffle block 13. By setting the arc-shaped baffle ring 10, the backflow route of the dust changes from a straight line to a bent line, reducing the dust backflow without restricting the entry of dust.

[0031] As a preferred implementation manner of the embodiment of the present invention, in order to more conveniently install the device with the fan, several groups of buckles 3 are fixedly installed on the outer wall of one end of the mounting sleeve 1, and the buckles 3 are directly clamped to the outer frame at the rear end of the fan, which is convenient for installation and disassembly.

[0032] As a preferred implementation manner of the embodiment of the present invention, a handle 6 is fixedly installed at the outer end of the rotating sleeve 5. When cleaning the dust, it is necessary to rotate the rotating sleeve 5. Direct rotation is necessarily laborious. By fixedly installing a handle 6 at the outer end of the rotating sleeve 5 and then rotating the handle to drive the rotating sleeve 5 to rotate, it is convenient and labor-saving.

[0033] An embodiment of the present invention provides a preferred implementation manner. An outer clamping plate 7 is arranged in the inner cavity of the mounting sleeve 1. The outer clamping plate 7 is rotationally matched with the rotating sleeve 5, that is, the outer clamping plate 7 is fixed and the rotating sleeve 5 can rotate along the inner wall of the outer clamping plate 7. The outer clamping plate 7 is detachably clamped with the mounting sleeve 1. The main function of the outer clamping plate 7 is to clamp the rotating sleeve 5 and facilitate manual disassembly and cleaning.

[0034] The rotating sleeve 5 is rotatably installed on the outer wall of the inner sleeve 2. When the rotating sleeve 5 is rotated, it is easy for the rotating sleeve 5 to move back and forth along the outer wall of the inner sleeve 2. Therefore, an embodiment of the present invention provides a preferred implementation manner. A limiting ring 8 is fixedly installed on the outer wall of the inner sleeve 2. A limiting groove 20 that cooperates with the limiting ring 8 is provided on the inner wall of the rotating sleeve 5. The rotating sleeve 5 is clamped with the inner sleeve 2 through the limiting groove 20 and the limiting ring 8, restricting the forward and backward movement of the rotating sleeve 5 along the outer wall of the inner sleeve 2.
