DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 In this embodiment, a residential building bathroom exhaust device includes a mounting plate 1, a fan cover 2 is fixedly mounted on the top of the mounting plate 1, a ventilation fan 3 is arranged inside the fan cover 2, a first connecting air duct 4 is fixedly mounted on the top of the fan cover 2, a bathroom environment optimization mechanism 5 is arranged on the top of the first connecting air duct 4, and a second connecting air duct 6 is fixedly mounted on the top of the bathroom environment optimization mechanism 5;

[0026] The toilet environment optimization mechanism 5 includes an equipment box 501, a connecting pipe 502, an ultrasonic atomizing nozzle 503, a floral water storage tank 504, a small delivery pump 505, an ultrasonic generator 506, an air nozzle 507, a small fan 508, a filter box 509, a filter element 510, an air heating box 511 and an air heating rod 512. The equipment box 501 is fixedly installed on the top of the first connecting air duct 4, and the connecting pipe 502 is fixedly installed inside the equipment box 501. The ultrasonic atomizing nozzle 503 is fixedly installed on the inner left wall of the connecting pipe 502. A floral water storage tank 504 is fixedly installed inside the equipment box 501, a small delivery pump 505 is fixedly installed inside the equipment box 501, an ultrasonic generator 506 is fixedly installed inside the equipment box 501, an air nozzle 507 is fixedly installed on the inner right wall of the connecting pipe 502, a small fan 508 is fixedly installed inside the equipment box 501, a filter box 509 is fixedly installed inside the equipment box 501, a filter element 510 is arranged inside the filter box 509, an air heating box 511 is fixedly installed inside the equipment box 501, and an air heating rod 512 is arranged inside the air heating box 511.

[0027] Specifically, the floral water storage tank 504 stores floral water, which can absorb and neutralize odor molecules in the air, remove persistent or stubborn odors inside the bathroom, and can repel mosquitoes to a certain extent, making the environment inside the bathroom more comfortable.

[0028] Specifically, the function of the filter element 510 inside the filter box 509 is to prevent the outside air drawn by the small fan 508 from containing dust and particulate matter. The filter element 510 includes a glass fiber filter plate and an activated carbon filter plate. The glass fiber filter plate is mainly used to intercept larger particles of impurities, such as dust, particulate matter, etc.; while the activated carbon filter plate mainly absorbs harmful gases and odors in the air, preventing the outside air drawn by the small fan 508 from affecting the air quality inside the bathroom.

[0029] Specifically, the ultrasonic generator 506 generates high-frequency vibration and transmits it to the ultrasonic atomizing nozzle 503, so that the floral water delivered by the small delivery pump 505 inside the ultrasonic atomizing nozzle 503 produces tiny water droplets. These water droplets carry fragrance and are spread in the air inside the bathroom under the action of the ventilation fan 3, adsorbing and neutralizing odor molecules in the air, and removing the odor in the internal environment of the bathroom.

[0030] To sum up, the bathroom exhaust device of the residential building, through the bathroom environment optimization mechanism 5, when the exhaust inside the bathroom is completed, controls the ventilation fan 3 to reverse and supply air to the inside of the bathroom. At this time, the ultrasonic generator 506 activates the ultrasonic atomizing nozzle 503, and vibrates the liquid in the floral water storage tank 504 drawn by the small delivery pump 505 into tiny water droplets. These water droplets carry fragrance and are spread in the air inside the bathroom under the action of the ventilation fan 3, adsorbing and neutralizing odor molecules in the air, and removing the odor existing in the internal environment of the bathroom.

[0031] Furthermore, in the exhaust device for the bathroom of the residential building, the outside air extracted by the small fan 508 is filtered by the filter element 510 inside the filter box 509, then enters the interior of the air heating box 511 and is heated by the air heating rod 512, and enters the bathroom through the air nozzle 507 under the action of the ventilation fan 3 to heat the inside of the bathroom, so that the temperature inside the bathroom is always maintained at a high state. On the one hand, in winter or in a cold environment, it provides users with a warm and comfortable use environment, and on the other hand, it helps to accelerate the evaporation of moisture on the ground, which can effectively reduce slip accidents caused by moisture, improve the safety of the bathroom, and solve the problem that the bathroom exhaust device lacks the function of deeply optimizing the internal environment of the bathroom and removing odors. It mainly relies on physical methods to discharge air and supplement fresh air from the outside, which has limited effect on solving the problem of persistent or stubborn odors in the bathroom and the problem that the ground is in a wet state for a long time and is easy to slide.
