Description

Technical Field

[0001] This application relates to the field of filter technology, and in particular to an anti-clogging filter. Background Technology

[0002] Air filters are used to remove impurities from gases. Existing air filters consist of a housing, filter element, and air pipe connector. Gas passes through the filter element's filter material to achieve the effect of filtering impurities. The existing filter element consists of a filter screen and a support frame. However, during operation, impurities in the air adhere to the filter screen. After prolonged use, excessive impurities accumulate on the screen, clogging it and reducing the airflow of the filter, thus lowering its processing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an anti-clogging filter element that addresses the shortcomings and deficiencies of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The device includes a mounting base, a filter element, and a top cover. The filter element is located between the mounting base and the top cover. The filter element includes a mounting frame and multiple filter screens. Multiple inclined baffles are evenly arranged from top to bottom on the outer periphery of the mounting frame. The inclined baffles are inclined outward from top to bottom. The upper end of the inclined baffle is connected and fixed to the side wall of the mounting frame. There is a vent hole between the lower end of the inclined baffle and the mounting frame. The filter screen is horizontally arranged in the vent hole.

[0006] Preferably, the mounting frame is composed of multiple splicing frames, the inclined baffle is located at the lower end of the splicing frame, the upper end of the splicing frame is inserted into the lower end of the inclined baffle of another splicing frame, four fixing rods are evenly inserted into the outer periphery of the inclined baffle, and fixing holes for the fixing rods to be inserted and fixed are evenly opened on the outer side wall of the upper end of the splicing frame.

[0007] Preferably, the upper surface of the filter screen has four grooves evenly distributed around its circumference, and the fixing rod is embedded and fixed in the grooves.

[0008] Preferably, the inner sidewall of the groove is disposed on the clamping block, and the clamping block is clamped and fixed to the sidewall of the fixing rod.

[0009] Preferably, the outer end of the fixing rod is rotatably connected to a pull ring.

[0010] Preferably, a vibration motor is provided on the lower end face of the mounting base.

[0011] Preferably, the upper end of the uppermost splicing frame is provided with a first connecting seat, the upper end of the first connecting seat being inserted and fixed inside the upper end cover, and the lower end of the lowermost splicing frame is provided with a second connecting seat, the second connecting seat being inserted and fixed inside the mounting base.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. When the filter element is in operation, outside air passes through the filter screen of the vent hole, which then filters out impurities. Since the filter screen is placed horizontally and located at the lower end of the inclined baffle, when the filter element stops working, the impurities attached to the filter screen will move downwards and fall to the bottom of the mounting base under the action of gravity. This allows the filter screen to filter the air normally when the filter element starts working again, preventing impurities from clogging the filter screen and improving the stability of the filter element.

[0014] 2. When the filter element stops working, start the vibration motor to make the filter element shake, so that impurities can be quickly removed from the filter screen and impurities stuck in the filter screen can fall downwards, further improving the stability of the filter element.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] This application discloses an anti-clogging filter element.

[0022] Reference Figure 1The system includes a mounting base 1, a filter element 2, and an upper cover 3. The filter element 2 is located between the mounting base 1 and the upper cover 3. A water outlet pipe 4 is inserted and fixed to the middle of the upper end of the upper cover 3. The mounting base 1 is located above the upper cover 3. A first connecting seat 5 is fixed to the lower periphery of the upper cover 3 by bolts. A second connecting seat 6 is fixed to the upper periphery of the mounting base 1 by bolts. The upper end of the filter element 2 is installed and fixed to the lower end of the first connecting seat 5, and the lower end of the filter element 2 is installed and fixed to the upper end of the second connecting seat 6.

[0023] Reference Figure 2 and Figure 3 The filter element 2 includes a mounting frame 7 and multiple filter screens 8. The mounting frame 7 is composed of multiple splicing frames 9. An inclined baffle 10 is integrally provided on the lower periphery of the splicing frame 9. The inclined baffle 10 is placed inclined outward from top to bottom. An annular vent hole 11 is formed between the lower end of the inclined baffle 10 and the upper end of the splicing frame 9 below. The filter screen 8 is in the shape of a ring and is located in the vent hole 11. Four through holes 12 are evenly opened in the inner periphery of the side wall of the inclined baffle 10. Four fixing holes 13 are evenly opened in the outer periphery of the upper end of the splicing frame 9. The through holes 12 and the fixing holes 13 are radially corresponding. A fixing rod 14 is inserted and slidably inserted into the through hole 12. The inner end of the fixing rod 14 is inserted and fixed in the fixing hole 13. When the filter element is in operation, outside air passes through the filter screen 8 of the vent 11, which then filters impurities. Since the filter screen 8 is placed horizontally and located at the lower end of the inclined baffle 10, when the filter element stops working, the impurities attached to the filter screen 8 will move downwards and fall to the inner bottom of the mounting base 1 under the action of gravity, so that when the filter element starts working again, the filter screen 8 can filter the air normally, preventing impurities from clogging the filter screen 8.

[0024] Reference Figure 4 The filter screen 8 consists of four filter frames 15 and a fixing ring 16. The four filter frames 15 are installed and fixed on the upper end face of the fixing ring 16. A groove 17 is formed between two adjacent filter frames 15. The fixing rod 14 is embedded and fixed in the groove 17. A clamping block 18 is integrally fixed at both ends of the filter frame 15. The clamping block 18 is located on the side wall of the groove 17 and abuts against the side wall of the fixing rod 14.

[0025] The outer end of the fixing rod 14 is rotatably connected to a pull ring 19. When it is necessary to disassemble the fixing rod 14, the pull ring 19 can be pulled to disengage the fixing rod 14 from the fixing hole 13, and then the splicing frame 9 can be disassembled.

[0026] Reference Figure 1 The vibration motor 20 is fixed to the lower end of the mounting base 1 by bolts. When the vibration motor 20 is started, the filter element shakes, causing impurities to quickly detach from the filter screen 8 and allowing impurities stuck in the filter screen 8 to fall downwards.

[0027] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
