DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of this patent will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this patent. Obviously, the described embodiments are only a part of the embodiments of this patent, rather than all of the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this patent.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4This patent provides a technical solution: a moisture-proof and dust-proof bathroom heater, which includes a first housing 1. A heating lamp 2 is fixedly installed inside the first housing 1. A second housing 3 is fixedly installed on the right side of the first housing 1. An exhaust fan 4 is fixedly installed inside the second housing 3. A dust-absorbing cotton 5 is provided inside the second housing 3. A hole body 6 is provided on the dust-absorbing cotton 5. A filter screen 7 is fixedly installed at the bottom of the second housing 3. The second housing 3 and the filter screen 7 are detachably connected;

[0020] As Figure 2 shown, the hole body 6 is an irregular hole body, which can avoid excessive obstruction of the air flow by the dust-absorbing cotton 5. At the same time, the dust-absorbing cotton 5 can secondarily adsorb the dust entering the second housing 3 to avoid increasing the burden on the exhaust fan 4.

[0021] Threaded grooves 8 are provided at the four corners of the bottom of the first housing 1. A rubber ring 9 and a transparent plate 10 are provided at the bottom of the first housing 1. Through holes 11 are provided at the four corners of the bottom of the transparent plate 10. Bolts 12 are provided inside the through holes 11. The top ends of the bolts 12 penetrate through the rubber ring 9 and are screwed into the threaded grooves 8. The top of the transparent plate 10 is closely attached to the bottom of the rubber ring 9. The top of the rubber ring 9 is closely attached to the bottom of the first housing 1;

[0022] An annular groove 13 is provided at the bottom of the first housing 1. A convex ring portion 14 is integrally formed at the top of the rubber ring 9. The size and shape of the convex ring portion 14 match the internal size and shape of the annular groove 13. The convex ring portion 14 is inserted into the annular groove 13, and the convex ring portion 14 is closely attached to the inside of the annular groove 13.

[0023] Specifically, positioning grooves 15 are provided on the left and right sides of the top of the transparent plate 10. Positioning posts 16 are integrally formed on the left and right sides of the bottom of the rubber ring 9. The positioning posts 16 are completely inserted into the positioning grooves 15.

[0024] By setting the positioning posts 16 to be completely inserted into the positioning grooves 15, it is used to limit the pressing and fitting positions of the transparent plate 10 and the rubber ring 9 to avoid skewing.

[0025] Specifically, an annular groove 17 is provided on the inner side wall of the through hole 11. An annular ring 18 is integrally formed on the side wall of the bolt 12. The annular ring 18 is located inside the annular groove 17.

[0026] By setting the annular ring 18 to be located inside the annular groove 17, it is used to increase the integral effect of the bolt 12 and the transparent plate 10, and avoid the bolt 12 falling out of the through hole 11 and causing part loss after the transparent plate 10 is disassembled.

[0027] Specifically, the side wall of the bolt 12 does not contact the inner side wall of the through hole 11.

[0028] Specifically, the diameter of the annular ring 18 matches the inner diameter of the annular groove 17, and the outer side wall of the annular ring 18 is relatively attached and slid against the inner side wall of the annular groove 17.

[0029] By the side wall of the bolt 12 not contacting the inner side wall of the through hole 11, wear of the thread on the side wall of the bolt 12 when the bolt 12 rotates can be avoided. At the same time, by the outer side wall of the ring 18 fitting and sliding relative to the inner side wall of the ring groove 17, the movement track of the bolt 12 is defined, so that the bolt 12 can only move up and down in the through hole 11, avoiding the bolt 12 from skewing in the through hole 11 during installation.

[0030] Specifically, clamping rings 19 are attached to both the top and bottom of the dust-absorbing cotton 5, and the outer side wall of the clamping ring 19 is fixedly installed on the inner side wall of the second housing 3.

[0031] By providing two clamping rings 19, the dust-absorbing cotton 5 is clamped.

[0032] Working principle: The first housing 1 and the second housing 3 are embedded in the ceiling in the bathroom. The rubber ring 9 and the convex ring portion 14 are used to enhance the sealing effect of the first housing 1, avoiding water vapor from entering the first housing 1. The exhaust fan 4 extracts the air in the bathroom, and the air flow passes through the filter screen 7 and the dust-absorbing cotton 5, and the dust in the air flow can be adsorbed by the filter screen 7 and the dust-absorbing cotton 5.
