The sound-absorbing cotton structure includes sound-absorbing cotton pasted on the flat surface inside the metal cabin structure and buffer cotton for reducing the vibration of the fan 28 during operation. The surface of the buffer cotton for reducing the vibration of the fan 28 during operation is tightly attached to the metal volute surface of the centrifugal fan 28 after pasting. The double-inlet volute centrifugal fan 28 takes in air from both sides of the volute and discharges air through the air outlet.

[0046] The middle cabinet structure includes a main cabinet structure and an air outlet cabinet structure 7. The main cabinet structure is connected to one side of the main cabin structure where the fan is installed. The main cabinet structure includes a cabinet structure, a comprehensive purification system section, a control system, and a sound-absorbing cotton. The cabinet structure includes a bottom plate structure 26, left and right side wooden board structures 12, a rear full-sealed plate structure 29, a metal lining plate structure 18, a bottom inner lining plate structure 24, a front plate structure 13, and a rear enclosure structure 6. The bottom plate structure 26 is provided with a connecting hole for connecting to a metal base structure 8, a vent for matching the airflow of a double-inlet volute centrifugal fan 28 structure, and a front metal slot 15.

The cross-section of the air inlet channel structure gradually increases along the surface of the metal lining structure 18. The cross-sectional area of ​​the cross-section of the air inlet channel structure is the largest when it reaches the cross-section of the comprehensive purification system section. When the cross-section of the comprehensive purification system section is the largest, the overall surface wind speed of the incoming airflow can be reduced. Furthermore, the integrated purification system section can be in contact with the passing airflow for a longer time, and the long contact time can make the integrated purification system section achieve a more optimized purification effect. The lower edge of the metal lining plate structure 18 has an upwardly flanged narrow section flat surface, and the flanged narrow section flat surface is flush with the front sides of the left and right wooden board structures. A through hole is set on the flat surface of the flanged narrow section, and a nut is welded on the back of the through hole, and the nut is used to connect the fastening bolts of the front plate structure 13. Corrugated sealing cotton is pasted on the flat surface of the flanged narrow section. The bottom inner lining plate structure 24 is set near the bottom plate structure 26 at the lower part of the semi-enclosed channel structure.

The lining plate structure 24 can place the flat mechanical filter of the integrated purification system section. The front plate structure 13 includes a front plate, a tongue structure, and a safety switch touch structure. Bolt holes are set on both sides of the upper part of the front plate. The metal tongue structure 16 is a metal tongue piece connected on both sides of the lower edge of the front plate structure 13. The front plate structure 13 is installed by inserting the metal tongue structure 16 at the bottom into the front metal slot 15 on the bottom plate structure 26, and the upper two sides are connected and fixed with the metal lining plate structure 18 through the bolt holes on the front plate structure 13 using special bolts. The safety switch trigger structure is a device that can trigger the safety switch installed on the front plate structure 13. The safety switch trigger structure will only trigger the safety switch installed on the inner side of the left wooden board structure 12 after the front plate structure 13 is installed. The rear panel structure 6 is connected to the width ends of the left and right wooden board structures 12. There is a certain distance between the rear panel structure 6 and the rear full sealing plate structure 29. The rear panel structure 6 is a left-right symmetrical structure. The middle part of the rear panel structure 6 is hollowed out as a whole. The rear panel structure 6 can be embedded in the air outlet side cabinet structure 7. The left and right wooden board structures 12 are provided with metal slides and rails for placing the primary filter 19 and the high-voltage electrostatic module 20 in the comprehensive purification system section at the lower edge of the metal lining plate structure 18 installation position.

[0048] The comprehensive purification system section includes a primary filter 19 , a high-voltage electrostatic module 20 , a high-efficiency filter 21 , a first gas adsorption 22 , a second gas adsorption 23 , and a third gas adsorption 25 .

[0049] The primary filter 19 and the high-voltage electrostatic module 20 are installed on the metal slide grooves and rails of the left and right wooden boards 12 .

[0050] The primary filter 19 is a primary filter cotton structure fixed with a metal grid. The primary filter 19 can filter larger particles. Furthermore, it can protect the service life of the secondary filter element. The high-voltage electrostatic module 20 forces the particles passing through to be charged through high-voltage discharge at the cathode. Furthermore, the charged particles are supplemented when passing through the collection section due to the traction of the potential difference. The high-voltage electrostatic module 20 can capture most of the aerosol particles released by tobacco combustion. The aerosol particles contain liquid substances such as tar and nicotine. The high-voltage electrostatic module 20 removes most of the liquid substances in advance. Furthermore, the subsequent high-efficiency filter 21 and gas adsorption filter element are protected. The high-voltage electrostatic module 20 can be reused many times by means of cleaning, drying, etc. The location where the high-voltage electrostatic module 20 is placed is a certain distance away from the location where the high-efficiency filter 21 is placed. The high-efficiency filter 21 and the gas adsorption layer are both in the form of a flat plate structure. The high-efficiency filter 21 is arranged behind the high-voltage electrostatic module 20. On the one hand, the high-voltage electrostatic module 20 can better protect the service life of the high-efficiency filter element 21. On the other hand, the particles passing through the high-voltage electrostatic module 20 are more easily actively adsorbed by the surface of the high-efficiency filter 21 due to the electrostatic attraction in the microscopic state after being charged. Further, the purification effect of the high-efficiency filter 21 arranged after the high-voltage electrostatic module 20 is better. The gas adsorption layer is arranged after the high-efficiency filter 21. After the airflow is filtered by the high-voltage electrostatic module 20 and the high-efficiency filter 21, there are basically no liquid particles, which can effectively protect the gas adsorption layer. The gas adsorption layer is filled with different types of adsorbents using plastic honeycombs. The first gas adsorption layer 22, the second gas adsorption layer 23, and the third gas adsorption layer 25 are mainly used to adsorb harmful gases released by cigarette combustion. The adsorbents configured for the first gas adsorption layer 22, the second gas adsorption layer 23, and the third gas adsorption layer 25 are different, and the types of adsorbed gases are also different.

The main board is the circuit control system of the purification device. The display panel port is reserved on the main board. Further, it is convenient to upgrade the display end of the equipment in the future. The safety switch can ensure that the whole machine is automatically powered off after opening the front panel structure 13. Further, to protect the safety of the personnel who open the cover, the transformer is used to output different voltages in conjunction with the main board. The driving power supply of the high-voltage electrostatic module 20 is a transformer that converts the AC220V voltage into a DC8000V / 4000V high voltage. The socket strip is convenient for maintenance personnel to open the cover and use it for maintenance after power off. The socket strip is powered after the front panel structure 13 is opened and the whole machine is powered off. The silencer is pasted inside the air inlet channel surrounded by the left and right side wooden board structures 12, the rear full-sealing plate structure 29, and the metal lining plate structure 18 in the upper part of the cabinet structure. The cabinet structure 7 on the air outlet side is placed on the air outlet side cabin structure of the base structure 8 and embedded in the rear enclosure structure 6 on the rear side of the main cabinet structure. The cabinet structure 7 on the air outlet side includes a front plate, a rear plate, a left plate, a right plate, an upper sealing plate, and silencer. The upper part of the front plate is provided with an air outlet 5 of the purification device. The cross-sectional area of ​​the air outlet 5 must reach a certain area. The air outlet 5 is arranged in a certain rule. The form of the air outlet 5 is not limited to the louver form or the flat plate form. The rear plate is embedded with a nut connected to the rear full-sealing plate structure 29 of the main cabinet structure. The upper sealing plate uses a metal flat plate to seal the upper opening of the cabinet. The lower opening of the cabinet is directly connected to the air outlet channel of the metal base structure 8. The silencer is pasted on the inner side of the cabinet 6 on the air outlet side. The tabletop structure includes a tabletop 4, a wooden lining structure 17, an air inlet structure 2, and an ashtray structure. The tabletop 4 is supported by the wooden lining structure 17, and the tabletop 4 and the wooden lining structure 17 are bonded by structural adhesive.
