[0030] Example:

[0031] This utility model discloses a filter that improves ash storage capacity, as shown in the following embodiment. Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The filter housing includes a housing 1, a filter element 2, and a filter element holder 3. The filter element 2 has a ring-shaped cylindrical structure and is fitted onto the filter element holder 3. The filter element 2 can be purchased commercially without modification. The housing 1 has an internal cavity 11, and the filter element holder 3 is embedded in the housing 1 and located within the cavity 11. At least one air inlet 12 is provided on the circumferential sidewall of the housing 1; in this specific example, four air inlets 12 are provided. The air inlets 12 are located away from the bottom of the housing 1 and close to its upper edge. In the usage state, the opening 13 of the housing 1 faces upwards. Figure 1 As shown, multiple air inlets 12 are evenly spaced around the circumference of the housing 1 and are at the same height. By changing the air inlets 12 from bottom to side air intake, the intake is changed from a single air inlet 12 to multi-directional air intake, which increases the air intake volume and makes the air intake smoother. After dust is blocked by the filter element 2, it can accumulate at the bottom of the housing 1. The accumulated dust is less likely to affect the bottom because the air inlets 12 are relatively high. The housing 1 can collect dust and the dust is not easy to escape from the air inlets 12, thereby improving the overall air intake reliability and extending the cleaning and maintenance cycle.

[0032] refer to Figure 3 and Figure 4The filter element holder 3 includes a main frame 31 and a bottom tray 32. The outer diameters of both the filter element 2 and the bottom tray 32 are smaller than the inner diameter of the outer shell 1. A protruding post 321 is provided at the center of the bottom tray 32. Multiple support posts 311 are provided on the main frame 31, and the support posts 311 abut against the protruding post 321. The filter element 2 is fitted onto the support posts 311. The assembly structure of the filter element holder 3 facilitates the replacement or cleaning of the filter element 2. The support posts 311 limit the position of the filter element 2, keeping it in a stable position and preventing deformation, thus providing support for the filter element 2.

[0033] exist Figure 4 In this case, the outer periphery of the bottom tray 32 is provided with multiple protrusions 322, which are used to abut against the inner wall of the outer shell 1. In this way, the bottom tray 32 can be better secured in the inner cavity of the outer shell 1.

[0034] To reduce weight and material costs, the support column 311 is a hollow structure, with one end resting against the bottom tray 32 and the other end having an opening 312 on the upper surface of the main frame 31. This opening 312 can further collect dust. The air here has been filtered by a filter element, so there is relatively little dust.

[0035] A mounting groove 313 is provided in the middle of the top of the main frame 31. A connecting pipe 314 is provided in the center of the mounting groove 313. A sealing ring 315 and an anti-slip block 316 are provided on the connecting pipe 314. A claw 317 is provided on the mounting groove 313 at the position directly opposite to the anti-slip block 316. The end of the anti-slip block 316 has a guide bevel 318.

[0036] Connecting pipe 314 serves as the air outlet, and its structure facilitates pipe installation and prevents detachment, effectively improving installation reliability. A flexible hose can typically be fitted onto connecting pipe 314.

[0037] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
