[0028] As Figs. 1 to 3 shown, the embodiment of the utility model provides a public toilet is with removing peculiar smell device, including for purifying public toilet peculiar smell purification framework 1, the bottom of purification framework 1 is connected with purification liquid storage bottle 2, purification framework 1's input end bolt connection has air inlet pipeline 4, and the output end of purification framework 1 is equipped with drive assembly 3, and one side of purification framework 1 is fixedly connected with mounting seat 6, when the air quality monitoring sensor in public toilet detects peculiar smell or harmful gas concentration to be overproof, the whole removing peculiar smell device starts to work, and each component in the inside of purification framework 1, including heating wire in purification liquid storage bottle 2, enters standby state, prepares to carry out air purification, and the air with peculiar smell is inhaled into the inside of purification framework 1 through air inlet pipeline 4. The design of air inlet pipeline 4 optimizes the air flow path, reduces vortex and resistance, ensures that air can smoothly and efficiently enter the device, and at the same time, the heating wire in the inside of purification liquid storage bottle 2 starts to work, heats the purification liquid (usually a chemical solution with the ability to adsorb and decompose peculiar smell, harmful gas). As the temperature rises, the purification liquid begins to evaporate, producing steam with a purification effect, which enters the inside of purification framework 1 through a specific channel and mixes well with the inhaled peculiar smell air. The active ingredients in the steam chemically react or physically adsorb with the odor molecules and harmful gases in the air, converting them into harmless or low-toxic substances, thereby achieving air purification. The drive assembly 3 at the output end of purification framework 1 pushes the purified air to circulate, ensuring the continuous progress of the entire purification process. After a series of purification treatments inside purification framework 1, the peculiar smell and harmful gases are effectively removed, and the air becomes fresh. The purified air returns to the public toilet, providing a healthy and comfortable environment for users.

[0029] The above-mentioned scheme needs to be explained that drive assembly 3 is the existing public technology, therefore does not carry out too much repetition.

[0030] In this embodiment, as Fig. 3The auxiliary assembly is used for enhancing the flow rate of the inflowing gas, and is connected with the air inlet pipeline 4. The auxiliary assembly comprises a connecting piece 401 which is bolted with the input end of the purification frame 1. One side of the connecting piece 401 is fixedly connected with a pipeline body 402. A partition cavity 404 is formed in the inner wall of the pipeline body 402. An inclined booster plate 405 is fixedly connected to the inner wall of the partition cavity 404. An installation rack is fixedly connected to the inner end of the pipeline body 402. A booster fan 407 is rotatably connected to the installation rack. The edge of the booster fan 407 is located at one side of the partition cavity 404. The end of the fan blade of the booster fan 407 is inclined. A flow-through channel is formed in the pipeline body 402. The flow-through channel is formed in the inner wall of the air inlet end of the pipeline body 402. A plurality of annularly distributed communication holes 403 are formed in the flow-through channel and are in communication with the partition cavity 404. An outwardly protruding guide ring 5 is fixedly connected to the inner wall of the flow-through channel. The guide ring 5 is located at one side of the communication hole 403. A helical drainage groove 406 is formed in the inner wall of the flow-through channel. When the public toilet odor removal device is started, the booster fan 407 in the auxiliary assembly is also started. At this time, the booster fan 407 starts to rotate and generates suction force to prepare to suck external air. Under the action of the suction force of the booster fan 407, the external air enters the pipeline body 402 through the air inlet pipeline 4. The air first enters the partition cavity 404. Due to the inclined arrangement of the booster plate 405, the air is subjected to a certain guiding and accelerating action in the partition cavity 404. The accelerated air in the partition cavity 404 enters the flow-through channel through the annularly distributed communication holes 403. In this process, the guide ring 5 plays a role in further guiding the flow direction of the air to ensure that the air can smoothly enter the flow-through channel. At the same time, the design of the helical drainage groove 406 causes the air to form a vortex flow in the flow-through channel, further increasing the flow rate and turbulence of the air. The accelerated and vortex-flowing air finally enters the purification system through the input end of the purification frame 1 for subsequent purification treatment. The rotation of the booster fan 407 generates suction force, which is the main power source for driving the air flow. By adjusting the rotating speed of the booster fan 407, the air suction amount and flow rate can be controlled. The design of the partition cavity 404 provides a pre-acceleration space for the air. The inclined booster plate 405 further guides the flow direction of the air and increases its kinetic energy. The annularly distributed communication holes 403 ensure that the air can uniformly enter the flow-through channel from the partition cavity 404. The guide ring 5 plays a role in further guiding the flow direction of the air to prevent excessive resistance of the air in the flow-through channel. The design of the helical drainage groove 406 causes the air to form a vortex flow in the flow-through channel. This flow mode not only increases the flow rate and turbulence of the air, but also helps to improve the purification efficiency.

[0031] The utility model provides a working principle, when the air quality monitoring sensor in public toilet detects peculiar smell or harmful gas concentration is overproof, the whole peculiar smell removal device starts work, each component in the inside of purification frame 1, including the heating wire in the purification liquid storage bottle 2, enters standby state, prepares air purification, when the peculiar smell removal device of public toilet starts, the booster fan 407 in auxiliary component also starts along with it. The design of the air inlet pipe 4 optimizes the air flow path, reduces the vortex and resistance, ensures that the air can smoothly and efficiently enter the device, at the same time, the heating wire in the inside of the purification liquid storage bottle 2 starts work, heats the purification liquid (usually a chemical solution with the ability of adsorbing and decomposing peculiar smell and harmful gas). With the increase of temperature, the purification liquid starts to evaporate, generates steam with purification effect, the steam enters the inside of the purification frame 1 through a specific channel, fully mixes with the inhaled peculiar smell air, the active ingredients in the steam and the peculiar smell molecules and harmful gas in the air occur chemical reaction or physical adsorption, convert them into harmless or low-toxic substances, so as to realize air purification, the driving assembly 3 at the output end of the purification frame 1 pushes the circulating flow of the purified air, ensures the continuous progress of the whole purification process, after a series of purification treatment in the inside of the purification frame 1, the peculiar smell and harmful gas are effectively removed, the air becomes fresh, the purified air returns to the public toilet, provides a healthy and comfortable environment for the user.
