[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) In the present invention, when air circulates from bottom to top inside the body, it passes through multiple filter plates for filtration. During self-cleaning, the receiving cylinder moves upward to block the air inlet pipe, and the top end of the top plate contacts the bottom end of the ejector rod. Subsequently, the fan motor passes a reverse current, causing the fan blades to rotate for air back-blowing.

[0017] (2) In this invention, air enters the ammonia removal tank through the connecting pipe, enabling the air to contact water and dissolve ammonia into the water, which facilitates the treatment of air containing ammonia. When the air enters the treatment tank, it continuously passes through the desiccant and activated carbon, thereby drying the air and absorbing odors, improving the cleaning effect of the air.

[0018] (3) After the drive motor is started in this invention, the rotating shaft rotates. Since the driving gear meshes with the driven gear, the first roller and the two second rollers rotate, causing the first blade and the second blade to break the bubbles flowing through the water, enabling the air to fully contact the water, improving the ammonia absorption effect, preventing ammonia from being discharged into the external environment, and protecting the organisms in the external environment.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1 is given by Figures 1 - 6 The present invention includes a body 1, an intake pipe 2 is installed on the front of the body 1, a connecting pipe 3 is installed on the top of the body 1, an impurity filtration component 4 is installed inside the body 1, and a deodorization component 5 is installed on one side of the body 1;

[0030] The deodorization component 5 includes an ammonia removal tank 501 installed on one side of the machine body 1. One end of the connecting pipe 3 penetrates into the interior of the ammonia removal tank 501. A bubble destruction unit 502 is installed inside the ammonia removal tank 501. A suspension rod 507 is installed at the bottom of the ammonia removal tank 501. A treatment tank 504 is installed at the bottom end of the suspension rod 507. A partition 505 is installed inside the treatment tank 504. Exhaust holes 506 are evenly formed on the partition 505 and at the bottom end of the treatment tank 504. The interior of the ammonia removal tank 501 is filled with water. An inlet and a drain are installed on the ammonia removal tank 501. A connecting pipe 503 is installed at the top of the ammonia removal tank 501. The connecting pipe 503 is located on the side of the bubble destruction unit 502 away from the connecting pipe 3. The bottom end of the connecting pipe 503 is connected to the position above the partition 505 of the treatment tank 504. A desiccant is filled above the partition 505, and activated carbon is filled below the partition 505. Air enters the ammonia removal tank 501 from the connecting pipe 3, causing the air to contact the water and dissolve ammonia in the water, facilitating the treatment of air ammonia. When the air enters the treatment tank 504, the air continuously passes through the desiccant and activated carbon, thereby drying the air and absorbing odors, improving the cleaning effect of the air.

[0031] The bubble destruction unit 502 includes a first roller 5021 disposed inside the ammonia removal tank 501.

After the driving motor 5024 is started, the rotating shaft 5023 rotates. Since the driving gear 5025 meshes with the driven gear 5029, the first roller 5021 and the two second rollers 5026 rotate, so that the first blades 5022 and the second blades 5027 destroy the bubbles flowing through the water, enabling the air to fully contact the water, improving the ammonia absorption effect, preventing ammonia from being discharged into the external environment, and protecting the organisms in the external environment.

[0032] The impurity filtering component 4 includes a receiving cylinder 401 disposed inside the machine body 1. The outer wall of the receiving cylinder 401 is in close contact with the inner wall of the machine body 1. The bottom end of the receiving cylinder 401 is fixedly connected to the output end of the air cylinder 402. The air cylinder 402 is fixedly installed on the inner bottom wall of the machine body 1. The receiving cylinder 401 is located below the air inlet pipe 2. The top end of the receiving cylinder 401 is equiangularly installed with top rods 406. The top end of the top rod 406 is installed with a filtering unit 407. An external dust discharge groove 403 is opened on one side of the machine body 1 away from the connecting pipe 3. A door body 404 is installed inside the external dust discharge groove 403. An internal dust discharge groove 405 is opened on one side of the receiving cylinder 401 close to the external dust discharge groove 403. The filtering unit 407 includes a cylinder body 4071. The outer wall of the cylinder body 4071 is in close contact with the inner wall of the machine body 1. The bottom end of the cylinder body 4071 is installed with a bottom plate 4072. The bottom plate 4072 is arranged in a ring shape. Filtering plates 4074 are equidistantly arranged inside the cylinder body 4071. The outer wall of the filtering plate 4074 is in close contact with the inner wall of the cylinder body 4071. Filtering holes 4075 are evenly opened on the filtering plate 4074. The aperture of the filtering holes 4075 on the filtering plates 4074 from top to bottom increases in sequence. Springs are equiangularly installed at the bottom end of the filtering plate 4074. Adjacent two filtering plates 4074 are connected by springs. The spring at the bottom end of the lowermost filtering plate 4074 is fixedly connected to the bottom plate 4072. Above the cylinder body 4071 is provided with a top plate 4076. The top plate 4076 and the uppermost filtering plate 4074 are connected by a spring. Movable rods 4077 are equiangularly installed at the bottom end of the top plate 4076. The movable rods 4077 are movably installed inside movable grooves 4073. The movable grooves 4073 are equiangularly opened at the top end of the cylinder body 4071. A top block 4078 is installed at the top end of the top plate 4076. The top block 4078 is hemispherical. A fan motor 408 is installed inside the machine body 1. The fan motor 408 is located above the top plate 4076. Fan blades 409 are equiangularly installed on the outer side of the output shaft of the fan motor 408. A side plate 410 is installed on the output shaft of the fan motor 408. A top rod 411 is installed at the bottom of one end of the side plate 410. The end of the top rod 411 is spherical. The top rod 411 is located above the top block 4078. When the air flows upward inside the machine body 1, it passes through multiple filtering plates 4074 for filtering. During self-cleaning, the receiving cylinder 401 moves upward to block the air inlet pipe 2. The top end of the top plate 4076 contacts the bottom end of the top rod 411. Subsequently, a reverse current is introduced into the fan motor 408, causing the fan blades 409 to rotate for air back-blowing. At the same time, the top rod 411 continuously passes over the top block 4078, causing the springs to vibrate. Then, under the action of the back-blowing and the spring vibration, the dust on the filtering plates 4074 is shaken off into the receiving cylinder 401, completing self-cleaning and facilitating subsequent use.

[0033] Working principle: When in use, the fan motor 408 is turned on, causing the fan blade 409 to rotate with the output shaft, driving the air inside the high-speed rail toilet to enter the machine body 1 from the air inlet pipe 2. Subsequently, the air moves upward and is filtered by multiple filter plates 4074, then moves above the top plate 4076, while the impurities remain on the filter plates 4074. The filtered air enters the ammonia removal tank 501 from the connecting pipe 3. Subsequently, the ammonia in the air dissolves in water, and the air with ammonia removed enters the treatment tank 504 from the communicating pipe 503. Desiccants and activated carbon are filled on the upper and lower sides of the partition plate 505 respectively. When the air passes through the desiccants and activated carbon, the moisture and odor in the air are removed, thereby improving the air purification effect. When the air passes through the ammonia removal tank 501, the driving motor 5024 is turned on, causing the rotating shaft 5023 to rotate, and thus the first roller 5021 to rotate. The driving gear 5025 meshes with the driven gear 5029, causing the first roller 5021 and the two second rollers 5026 to rotate, and thus the first blade 5022 and the second blade 5027 to break the bubbles flowing through the water, enabling the air to fully contact the water and improving the ammonia absorption effect. After the air treatment is completed, through the cylinder 402, the receiving cylinder 401 is pushed upward to block the air inlet pipe 2. At this time, the bottom end of the ejector rod 411 contacts the top end of the top plate 4076. Subsequently, the fan motor 408 is supplied with reverse current, causing the fan blade 409 to rotate in the reverse direction, pushing the upper air to pass through the filter plate 4074 from top to bottom for back blowing. At the same time, the output shaft of the fan motor 408 rotates, driving the ejector rod 411 to continuously pass through the top block 4078, and then pushing the top plate 4076 to move up and down reciprocally, causing the springs on the filter plate 4074 to vibrate. Under the action of the spring vibration and air back blowing, the dust falls into the receiving cylinder 401, facilitating dust cleaning. Subsequently, the output end of the cylinder 402 drives the receiving cylinder 401 to return to its original position, and the external dust discharge groove 403 is opened to clean the dust from the internal dust discharge groove 405.
