[0003] Existing household air conditioners can generally only draw air from the room and then send it back to the room after heat exchange, but cannot introduce fresh air from the outside. Therefore, after long-term operation of household air conditioners in a relatively closed indoor environment, the air conditioner filter will be seriously dusty, the indoor air will be extremely polluted, and it is easy to produce odor. In addition, although the air outlet of existing household air conditioners has a large air volume, the human body feels poor. Long-term blowing can easily cause physical discomfort, and the elderly, children, etc. are prone to colds or rheumatism and other diseases.

[0004] In the related art, an air treatment module is provided in the air conditioner, and a purification module is provided in the air treatment module. The purification module can filter out liquid or solid particles in the polluted air, thereby purifying and treating the air, and improving the air purification performance of the air conditioner. However, after the air conditioner is used for a long time, a large amount of dust particles and harmful bacteria will adhere to the purification module, and the filter device needs to be frequently removed for cleaning, which is cumbersome and seriously affects the user's comfort.

[0005] Meanwhile, in the prior art, although a structure for detachably installing a purification module is provided on the fresh air device of the fresh air fan, a filter or purification module is detachably installed on the air inlet side of the air inlet module close to the fan module to filter the air delivered to the room. However, in order to ensure the purification effect, the purification module generally cuts off the entire air supply passage and is assembled with the drawer opening, and the size of the drawer opening is basically the same as that of the purification module, resulting in problems such as the purification module not being smoothly drawn and not being easy to disassemble or fix.

When the abutting column 1302c slides to the fixing port 1301b, the abutting column 1302c rotates under the compression of the elastic member 801d, so that the groove 1302b on the sliding part 1302a can be clamped on the guide inclined surface 1301c and / or the limiting protrusion 1301d. At this time, the elastic member 801d is compressed and fixed. The extrusion generates elastic potential energy, and the push switch is in a closed state, thereby locking the purification device 12; the purification device 12 is pressed again, and the abutment column 1302c rotates in the opposite direction again under the compression of the elastic member 801d, so that the groove 1302b on the sliding portion 1302a is disengaged from the guide slope 1301c and / or the limiting protrusion 1301d, and the push switch is in an open state. At this time, the elastic potential energy of the elastic member 801d is released, thereby opening the purification device 12.

[0086] As a preferred example of the present invention, Fig.10 As shown, a limit plate 902 is provided at the front end of the plug interface 9, and the limit plate 902 is used to limit the insertion displacement of the purification device 12. The limit plate 902 is arranged at any position inside the port of the plug interface 9, and a pull-out plate 1205 is arranged at the front end of the main board 1201 on the purification device 12. After the purification device 12 is installed in place in the plug interface 9, the pull-out plate 1205 can be extended into the plug interface 9 and limited by the limit plate 902. As an example of the present invention, the front end of the plug interface 9 is a shrinking port or a step-shaped structure with a gradually smaller cross-section. This setting facilitates the sealing of the limit pull-out plate 1205 at the front end of the plug interface 9, ensuring that the purification device 12 is assembled with the plug interface 9 to avoid air leakage. Preferably, the limit plate 902 can be provided at one, or two or more can be provided. As an example of the present invention, the limit plate 902 is provided at the front end of the stroke groove 801b on the left volute 801 and / or the right volute 802.

[0087] This arrangement facilitates the position limiting of the purification device 12 after it is inserted into the plug port 9, thereby ensuring the accuracy and reliability of locking the purification device 12 when it is pushed and pulled into place.

[0088] As a preferred example of the present invention, the front end of the purification device 12 and the front end of the plug interface 9 are plugged into and matched with the limiting groove 903 through a limiting component 1207 .

[0090] Preferably, Fig.19 , Fig. 20 As shown, the limit assembly 1207 is arranged on the pull-out plate 1205, and the limit assembly 1207 includes a limit pin and a hinge column 1207c. The limit pin is hingedly fixed to the pull-out plate 1205 through the hinge column 1207c, and the limit section 1207a can extend into the limit groove 903 for limiting under the action of rotation of the limit pin. The limit groove 903 is arranged at the front end of the limit plate 902.

[0091] Furthermore, the limiting pin includes a limiting section 1207a, and one end of the limiting section 1207a is hingedly connected to the hinge column 1207c.

[0092] Furthermore, the limiting pin further includes a handle 1207b, and the limiting section 1207a and the handle 1207b are respectively arranged on both sides of the hinge column 1207c. This arrangement facilitates the limiting section 1207a to rotate by rotating the handle 1207b, thereby conveniently and reliably realizing the insertion and limiting or separation of the limiting section 1207a and the limiting groove 903.

[0093] Preferably, a counterweight portion 1207d is provided at the end of the limiting segment 1207a away from the handle 1207b. The counterweight portion can be made of a material with a relatively high density, such as metal or non-metal material, such as granite, iron, copper, etc. This arrangement enables the limiting segment 1207a of the limiting component 1207 to be fixed in place under the action of its own weight after being inserted into the limiting groove 903, thereby achieving self-locking and preventing the limiting component 1207 from being separated from the limiting groove 903 due to shaking or accidental collision.

[0094] Preferably, a torsion spring is arranged between the limiting assembly 1207 and the pull plate 1205. This arrangement enables the counterweight on the limiting segment 1207a to drive the limiting segment 1207a to slide into the limiting groove 903 under the action of its own weight, and the torsion spring is deformed to generate elastic force to fix the limiting segment 1207a, thereby preventing the limiting segment 1207a from deflecting in the opposite direction after the user lets go.

[0095] Preferably, one or more limiting components 1207 may be provided on the pull-out plate 1205 .

When the abutting column 1302c slides to the fixing port 1301b, the abutting column 1302c rotates under the compression of the elastic member 801d, so that the sliding portion 1302a is moved forward. The groove 1302b on the part 1302a can be snapped onto the guide slope 1301c and / or the limiting protrusion 1301d. At this time, the push switch is in a closed state, the purification device 12 is installed in place, and the front end of the purification device 12 is locked with the volute assembly 8 through the limiting assembly 1207; when the purification device 12 needs to be removed, the limiting pin of the limiting assembly 1207 is rotated so that the limiting section 1207a of the limiting pin is separated from the limiting groove 903, and the elastic potential energy of the elastic member 801d is released, so that the purification device 12 is opened. This setting discloses a structure in which the positioning column 801c is set at the rear end of the travel groove 801b, and the positioning hole 1206 is set on the purification device 12 to realize that the purification device 12 can be automatically ejected when it is pulled out.
