Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] Reference Figures 1 to 3 According to a first aspect of the present invention, a gas equipment air filter assembly includes a filter box 200 and a filter element 300. The filter box 200 has an open-top filter chamber 210 inside. The filter box 200 has a cover plate 100 on top that can cover the open-top of the filter chamber 210. The cover plate 100 has an air inlet 110 communicating with the filter chamber 210. The side wall of the filter box 200 has an air outlet 220 communicating with the filter chamber 210. The filter element 300 is usually a filter screen or filter cotton. The filter element 300 is located in the filter chamber 210. The cover plate 100 has an installation port 120 at a position corresponding to the filter element 300. The filter element 300 can pass through the installation port 120 to enter or leave the filter chamber 210.

[0032] By adopting the above structure, when the filter element 300 needs to be cleaned, it can be quickly removed from the mounting port 120 for cleaning. After cleaning, the filter element 300 can be quickly reinstalled into the air filter assembly through the mounting port 120. Compared with traditional gas equipment air filter assemblies, the air filter assembly of this embodiment of the present invention, by providing the mounting port 120, enables quick disassembly and installation of the filter element 300. The disassembly and installation operations are simple and convenient, facilitating the cleaning of the filter element 300.

[0033] It should be noted that air can flow into the filter chamber 210 from the air inlet 110, and the air flows through the filter element 300 in the filter chamber 210 and flows out from the air outlet 220. During this process, the filter element 300 filters the air.

[0034] It should be noted that in some embodiments, the edge of the cover plate 100 has a flange, which can enhance the structural strength of the cover plate 100 and make the cover plate 100 less prone to bending deformation or breakage.

[0035] It is understood that the filter element 300 is usually a filter screen or filter cotton, but depending on actual needs, the filter element 300 can also use other types of air filter materials, and this utility model does not make specific limitations in this regard.

[0036] Reference Figure 1 In some embodiments of this utility model, a cover 400 is also included, which is detachably installed on the cover plate 100 and covers the installation opening 120.

[0037] By adopting the above structure, after the filter element 300 is installed in the filter chamber 210, covering the mounting port 120 with the cover 400 can prevent dust and impurities from entering the filter chamber 210 from the mounting port 120; the cover 400 can also fix the filter element 300 in place, preventing the filter element 300 from falling off the mounting port 120; the cover 400 can also seal the mounting port 120, preventing air entering the filter chamber 210 from flowing out from the mounting port 120 and affecting the air intake efficiency, or preventing outside air from flowing in from the mounting port 120 and affecting the filtration effect.

[0038] It is understood that the cover 400 is usually a plate-shaped structure, which makes the cover 400 and the cover 100 more flat and aesthetically pleasing when installed on the cover plate 100. However, depending on actual needs, the cover 400 can also be a block-shaped structure, a box-shaped structure or other structures. This utility model does not make specific limitations on this.

[0039] Reference Figure 1In some embodiments of this utility model, the cover 400 has a first connecting hole 410, and the periphery of the mounting opening 120 has a second connecting hole 121. The first connecting hole 410 corresponds to the second connecting hole 121, and the connector passes through the first connecting hole 410 and the second connecting hole 121 so that the cover 400 and the cover plate 100 are detachably connected.

[0040] By adopting the above structure, the connector can securely install the cover 400 on the cover plate 100, making it difficult for the cover 400 to fall off the cover plate 100, ensuring the normal operation of the cover 400. Furthermore, the connector is a detachable connection, which allows the cover 400 to be easily removed from the cover plate 100 or installed on the cover plate 100.

[0041] It should be noted that the cover 400 has a first connecting hole 410 on all four sides, and the mounting port 120 has a second connecting hole 121 on all four sides. Thus, the connectors are distributed around the cover 400 for connection, making the connection more stable and preventing one end of the cover 400 from lifting up.

[0042] It is understood that the connector is usually a screw or bolt. Depending on the actual needs, the connector can also be other connecting parts such as a connecting pin. This utility model does not make any specific limitation on this.

[0043] In daily use, rainwater can easily enter the filter box 200 from the air inlet 110. At the same time, condensation can easily occur in the filter box 200. Excessive accumulation of rainwater and condensation in the filter box 200 can affect the normal operation of the air filter components. For example, long-term accumulation of rainwater and condensation in the filter box 200 can easily breed bacteria. Excessive accumulation of rainwater and condensation can easily flow out from the air outlet 220 and damage other equipment.

[0044] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the bottom of the filter box 200 is provided with a water outlet 230.

[0045] By adopting the above structure, the outlet 230 can discharge rainwater and condensate water and other wastewater from the filter box 200, thus preventing rainwater and condensate water and other wastewater from accumulating in the filter box 200 for a long time or in excessive amounts.

[0046] It should be noted that the outlet 230 is connected to a pipe and guides rainwater and condensate water and other wastewater to the outside through the pipe, or guides rainwater and condensate water and other wastewater to the wastewater collection device through the pipe.

[0047] Reference Figure 1 and Figure 2In some embodiments of this utility model, the water outlet 230 is located at the lowest point of the bottom of the filter box 200.

[0048] By adopting the above structure, wastewater such as rainwater and condensate will flow to the lowest point of the bottom of the filter box 200 under the action of gravity. Therefore, setting the outlet 230 at the lowest point of the bottom of the filter box 200 helps to discharge wastewater such as rainwater and condensate from the filter box 200 more quickly.

[0049] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the sidewall of the filter box 200 is provided with an inwardly bent flange 240.

[0050] By adopting the above structure, the flange 240 can enhance the strength of the side wall of the filter box 200, making the filter box 200 less prone to bending and deformation. In some embodiments, the filter element 300 abuts against the flange, and the flange plays a role in fixing, supporting and sealing the filter element 300.

[0051] Reference Figure 1 and Figure 3 In some embodiments of this utility model, a double-layer sleeve 500 is also included. The double-layer sleeve 500 is installed at the air inlet 110. The double-layer sleeve 500 includes an inner sleeve 510 and an outer sleeve 520. An air inlet channel 521 is provided between the inner sleeve 510 and the outer sleeve 520. An air outlet channel 511 is provided inside the inner sleeve 510. The air inlet channel 521 connects to the filter chamber 210. A clearance hole 250 is provided on the bottom wall of the filter box 200. The inner sleeve 510 extends into the filter chamber 210 and is inserted into the clearance hole 250. The outer wall of the inner sleeve 510 is sealed to the inner wall of the clearance hole 250. The air inlet channel 521 is the channel for air to enter the filter chamber 210, and the air outlet channel 511 is the channel for exhausting exhaust gases such as smoke from other components to the outside.

[0052] By adopting the above structure, the double-layer sleeve 500 allows the air intake and exhaust processes to occur at the same location, thereby saving space and reducing costs. Since exhaust gases such as smoke are generally at a higher temperature than air, the double-layer sleeve 500 allows the exhaust gases to heat the air in the air intake channel 521 during the exhaust process in the air outlet channel 511, thus reducing heat loss and increasing thermal efficiency. Sealing the outer wall of the inner sleeve 510 with the inner wall of the relief hole 250 prevents air from flowing out of the relief hole 250 from the filter chamber 210, which would affect the air intake filtration effect.

[0053] It should be noted that the outer sleeve 520 can extend through the air inlet 110 into the filter chamber 210, or it can abut against the cover plate 100; the inner sleeve 510 can extend through the relief hole 250 into the outside of the filter box 200, or it can abut against the inner wall of the filter box 200.

[0054] It should be noted that in some embodiments, the air inlet channel 521 is provided with reinforcing ribs 530. The reinforcing ribs 530 can enhance the structural strength between the inner sleeve 510 and the outer sleeve 520, and can also prevent the inner sleeve 510 from shaking due to the impact of flowing gas. The reinforcing ribs 530 can also guide the air in the air inlet channel 521, so that the air flows through the air inlet channel 521 in a more orderly manner.

[0055] It is understood that the outer wall of the inner sleeve 510 can achieve a sealing effect by tightly adhering to the inner wall of the relief hole 250, or by setting a sealing structure between the outer wall of the inner sleeve 510 and the inner wall of the relief hole 250, such as setting a sealing ring, sealing plate or other sealing structure. This utility model does not make specific limitations in this regard.

[0056] Reference Figure 1 and Figure 3 In some embodiments of this utility model, the inner sleeve 510 and the outer sleeve 520 are coaxially arranged.

[0057] By adopting the above structure, the coaxial arrangement of the inner sleeve 510 and the outer sleeve 520 allows air to flow more evenly through the air inlet channel 521, improving air intake efficiency. Simultaneously, exhaust gases such as smoke in the air outlet channel 511 can more evenly heat the air in the air inlet channel 521. The coaxial arrangement also ensures more even stress distribution on the inner sleeve 510 and the outer sleeve 520.

[0058] Reference Figure 1 and Figure 3 In some embodiments of this utility model, the upper end of the inner sleeve 510 is at a higher horizontal height than the upper end of the outer sleeve 520.

[0059] By adopting the above structure, exhaust gases such as smoke are discharged to the outside through the exhaust duct 511, and air flows into the intake duct 521 from all sides of the outer sleeve 520. The inner sleeve 510, which is at a higher horizontal height, can prevent the exhaust gases discharged in the exhaust duct 511 from being sucked back into the intake duct 521, so that the exhaust gases are discharged more cleanly and thoroughly.

[0060] A gas appliance according to a second aspect of the present invention includes a gas appliance body, the gas appliance body being configured with a gas appliance air filter assembly as described in the above embodiment.

[0061] The gas appliance of this embodiment employs the aforementioned air filter assembly. When the filter element 300 needs cleaning, it can be quickly removed from the mounting port 120 for cleaning. After cleaning, the filter element 300 can be quickly reinstalled into the air filter assembly through the mounting port 120. Compared to traditional gas appliance air filter assemblies, the air filter assembly of this embodiment, with its mounting port 120, enables quick disassembly and installation of the filter element 300. The disassembly and installation operations are simple and convenient, facilitating the cleaning of the filter element 300.

[0062] It should be noted that the cover plate 100 can be part of the housing of the gas equipment; the cover plate 100 can also be an independent component, in which case the housing of the gas equipment has an opening for installing the cover plate 100 and installing the cover plate 100 in this opening.

[0063] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
