A purification component 6 is installed on top of the reverse-blade fan 5 inside the mounting housing 1, which purifies the airflow. The component 6 is located on top of the reverse blade fan 5 and at the bottom of the activated carbon mesh 10, which facilitates the extraction of air. After filtration, the air is sprayed with fragrance gas from the air freshener bottle 601 in the purification component 6, thereby improving the purification effect on bathroom odors. The purification component 6 includes an air freshener bottle 601, a signal receiver 602, a signal line 603, and a solenoid valve 604 installed on one side of the air freshener bottle 601. A baffle 7 is provided at the bottom of the mounting shell 1. The air freshener bottle 601 is an automatic spray type, and the nozzle is equipped with a solenoid valve 604.

[0025] The buckle body 8, which is fixed inside the mounting shell 1 and installed in conjunction with the baffle 7, has a mesh design on both sides inside the baffle 7 to prevent insects from flying into the positive blade fan 4 and the negative blade fan 5. The buckle body 8 is made of plastic, which facilitates the assembly of the baffle 7 to the bottom of the mounting shell 1. A dust exhaust shell 9 is fixedly connected to one side of the mounting shell 1. A pipe is provided on the side of the dust exhaust shell 9 to facilitate the drainage and flow of gas. An activated carbon mesh 10 is inserted into one side inside the mounting shell 1. A drive assembly 11 for cleaning the activated carbon mesh 10 is fixedly connected to one side of the mounting shell 1. By installing the drive assembly 11 on one side of the mounting shell 1, the impurities filtered on the top of the activated carbon mesh 10 can be automatically cleaned, reducing the frequency of manual cleaning and lowering maintenance costs. The drive assembly 11 includes a motor 1101. Dust exhaust pipes 12 are fixedly connected to both sides of the top of the mounting shell 1.

[0026] Support plates 13 are provided on both the front and rear sides of the bottom of the activated carbon mesh 10. These support plates 13 are fixed to the front and rear sides inside the mounting shell 1, providing bottom support and assisting in the insertion and installation of the activated carbon mesh 10. The two sides of the support plates 13 are fixedly connected to the partition plate 3 and the mounting shell 1, respectively. A dust collection shell 14 for collecting dust is inserted into the bottom of the inner cavity of the dust discharge shell 9. The front side of the dust collection shell 14 is recessed and fixedly connected to a handle 15. By inserting the dust collection shell 14 into the dust discharge shell 9, the activated carbon mesh 10 can be controlled by a drive assembly. The dust removed by component 11 is guided by the dust discharge shell 9 and falls into the interior of the dust collection shell 14 for collection, improving the convenience of dust cleaning. The handle 15 inside the groove of the dust collection shell 14 makes it easy to remove the dust collection shell 14 from the inside of the dust discharge shell 9 for cleaning. A reinforcing block 21 is fixedly connected to the bottom of the dust discharge shell 9. The reinforcing block 21 is fixed between the mounting shell 1 and the dust discharge shell 9, which can improve the connection strength between the dust discharge shell 9 and the mounting shell 1 and ensure the stability of the two for long-term use. One side of the reinforcing block 21 is fixedly connected to the mounting shell 1.

[0027] The motor 1101 is fixed to one side of the mounting housing 1. The output end of the motor 1101 extends into the interior of the mounting housing 1 and is fixedly connected to a screw 1102. An internal threaded plate 1103 is threaded onto the surface of the screw 1102. A brush plate 1104 is fixedly connected to the bottom of the internal threaded plate 1103. The motor 1101 is electrically connected to an external control panel via a cable. When the operator needs to automatically clean the activated carbon mesh 10, the motor 1101 is started. At this time, the screw 1102 begins to rotate, cooperating with the internal threaded plate 1103 to perform limited movement on the surface of the slide rod 1105. As the internal threaded plate 1103 moves, the brush plate 1104 sweeps away the dust and guides the dust on the top of the activated carbon mesh 10 to one side for cleaning. At the same time, the motor 1101 can reciprocate to ensure the thoroughness of the cleaning process and guarantee the cleanliness of the brushing effect. The internal threaded plate 1103 has a sliding rod 1105 slidably connected inside at the end away from the screw 1102. The two ends of the sliding rod 1105 are fixedly connected to the partition plate 3 and the mounting shell 1, respectively. The bottom of the brush plate 1104 is in active contact with the activated carbon mesh 10.

[0028] One side of the activated carbon mesh 10 extends through to the outside of the mounting shell 1 and is fixedly connected to a connecting plate 16. The connecting plate 16 extends to the outside of the slot and cooperates with the positioning plate 17 fixed on one side of the dust discharge shell 9. When the user needs to replace or maintain the activated carbon mesh 10, he pulls the pull rod 20 to disengage the insertion rod 19 from the inside of the positioning plate 17 and simultaneously compresses the spring 18. At this time, the user can pull the connecting plate 16 to remove the activated carbon mesh 10. Similarly, the reverse operation can be used to reset and install the activated carbon mesh 10. A slot for disassembling the activated carbon mesh 10 is opened on one side inside the mounting shell 1. The positioning plate 17 is fixedly connected to one side inside the dust discharge shell 9. The bottom of the connecting plate 16 is fixedly connected to a spring 18. The bottom of the spring 18 is fixedly connected to an insertion rod 19. The top of the insertion rod 19 is fixedly connected to a pull rod 20 that extends through to the outside of the connecting plate 16.

[0029] A signal receiver 602 is installed on the top of an air freshener bottle 601. A pressure gauge 605 is fixedly connected to one side of the air freshener bottle 601. The signal receiver 602 is connected to the solenoid valve 604 at the outlet of the air freshener bottle 601 and the pressure gauge 605 via a signal line 603. When air purification is required, the signal receiver 602 is controlled via the control panel to open the solenoid valve 604 on the air freshener bottle 601 and spray out the freshener. At this time, the freshener is between the activated carbon mesh 10 and the reverse blade fan 5. The reverse blade fan 5 is then controlled to filter the outside air through the activated carbon mesh 10 and mix it with the freshener before it is discharged into the room from the bottom of the baffle 7, thus purifying the indoor air.

[0030] Working principle: When it is necessary to extract gas from the bathroom, the control panel installed on the wall turns on the forward-leaf fan 4 to draw the gas through the mounting shell 1 into the dust exhaust pipe 12 and guide it out. If the user needs to purify the bathroom odor, the forward-leaf fan 4 is turned off, and then the reverse-leaf fan 5 is turned on to draw outside air through the dust exhaust pipe 12 into the space between the partition 3 and the reverse-leaf fan 5. Then, the control panel controls the signal receiver 602 to open the solenoid valve 604 on the air freshener bottle 601 and spray the freshener. At this time, the freshener is between the activated carbon mesh 10 and the reverse-leaf fan 5. Then, by controlling the reverse-leaf fan 5, the outside air is filtered through the activated carbon mesh 10 and discharged into the room from the bottom of the baffle 7 along with the freshener, purifying the indoor air. If the user needs to clean the activated carbon mesh 10, the drive motor 1101 is started. At this time, the screw 1102 starts to rotate and cooperates with the internal thread plate 1103 to move in a limited position on the surface of the slide rod 1105. As the internal thread plate 1103 moves, the brush plate 1104 will sweep away the dust and guide the dust on the top of the activated carbon mesh 10 to the inside of the dust discharge shell 9 on one side, and then fall into the dust collection shell 14 for collection.
