Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0031] In the description of the present invention, it should be noted that the terms "upper", "inner", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are directions or positional relationships in which the inventive product is usually placed when in use. These are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0032] Please combine Figure 1 and Figure 2 The present invention provides a toilet waste gas deodorizer 100, including a waste gas treatment chamber 110, a filter 120, a catalytic component 130 and a photocatalytic light source 140.

[0033] The exhaust gas treatment chamber 110 has an air inlet and an air outlet respectively located at its two ends. The filter 120 is arranged in the exhaust gas treatment chamber 110 and close to the air inlet. The catalytic component 130 is coated with a photocatalyst and has a plurality of pores, the size of which is adjustable. The photocatalytic light source 140 is arranged between the filter 120 and the catalytic component 130.

[0034] Through the above-mentioned arrangement, when the toilet waste gas deodorizer 100 is used to purify the waste gas to be purified, the waste gas enters the waste gas treatment chamber 110 through the air inlet of the waste gas treatment chamber 110, and is filtered by the filter 120. After the waste gas to be purified is purified under the irradiation of the photocatalytic light source 140 and the action of the catalytic component 130, it is discharged to the external environment through the pores and the air outlet of the catalytic component 130. When the above-mentioned toilet waste gas deodorizer 100 purifies the waste gas to be treated, since the pore size of the catalytic component 130 is adjustable, the pore size can be adjusted according to the content of harmful gases in the waste gas to be purified, thereby effectively ensuring that the waste gas is completely purified, so as to improve the purification effect of the toilet waste gas deodorizer 100.

[0035] The shape of the exhaust gas treatment chamber 110 can be arbitrary, such as bottle-shaped or cylindrical, which is not specifically limited here and can be set according to actual needs.

[0037] Optionally, in this embodiment, the filter 120 includes an activated carbon honeycomb filter layer, which is arranged in the exhaust gas treatment chamber 110 at one end close to the air inlet to filter the gas entering the exhaust gas treatment chamber 110 through the air inlet, and the activated carbon honeycomb filter layer is coated with a photocatalyst on the side close to the photocatalytic light source 140.

[0038] In order to facilitate the placement of the filter 120 in the exhaust gas treatment chamber 110 , in the present embodiment, the filter 120 further includes a rubber spring sheet, and the activated carbon honeycomb filter layer is fixed in the exhaust gas treatment chamber 110 via the rubber spring sheet.

[0041] Among them, the filler can include at least one of multiple elastic spheres such as polypropylene (PP) ball fillers, acrylonitrile butadiene styrene (ABS) ball fillers, polystyrene (PS) ball fillers or suspended fluidized bed filler (MBBR) ball fillers, so as to form pores when the multiple elastic spheres are placed in the containing structure. It can also be made of plastic or rubber with pores, so as to change the size of the pores when the cover moves along the axial direction of the containing cavity.

[0042] Optionally, in this embodiment, the filler includes a plurality of PP ball fillers coated with a photocatalyst.

[0043] The bottom of the accommodating cavity or the cover is arranged at a side close to the filter 120 , and the cover or the bottom of the accommodating cavity is arranged side by side with the filter 120 in the exhaust gas treatment cavity 110 .

[0044] In order to facilitate adjustment of the size of the pore, in the present embodiment, a plurality of limit assemblies are provided in the accommodating cavity and are respectively used to control the distance between the cover body and the accommodating cavity.

[0045] Through the above arrangement, when the concentration of the exhaust gas to be purified is different, the cover body can be set at different distances from the accommodating cavity through different limiting components, so as to adjust the pore size to adjust the reaction time and achieve the purpose of achieving the best purification effect.

[0046] In order to further improve the purification effect and enable the photocatalytic light source 140 to irradiate as many areas as possible, in this embodiment, the containing structure includes a wire mesh cage, which includes a wire mesh cage cavity and a wire mesh cover arranged in the wire mesh cage cavity and capable of moving along the axial direction of the wire mesh cage cavity.

[0047] The containing structure comprises a wire mesh cage, which comprises a wire mesh cage cavity and a wire mesh cover which is arranged in the wire mesh cage cavity and can move along the axial direction of the wire mesh cage cavity.

[0056] By arranging a plurality of ultraviolet lamps on the inner wall of the exhaust gas treatment chamber 110, it is effectively ensured that light irradiation at different positions in the exhaust gas treatment chamber 110 is uniform, so that the purification effect of the exhaust gas to be purified is better.

[0057] When the cross section of the exhaust gas treatment chamber 110 is rectangular or square, the number of the ultraviolet lamps is 4, and they are respectively arranged on the four side walls of the exhaust gas treatment chamber 110 .
