[0022] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] See also Figures 1 to 4 The utility model provides an installation structure of an air duct 1 and a filter screen 2, comprising:

[0024] The air duct 1 is formed with a ventilation cavity 101 arranged along the length direction thereof, and a mounting opening 102 formed on the side of the air duct 1, and the ventilation cavity 101 is connected to the mounting opening 102;

[0025] The filter screen 2 is slidably disposed in the ventilation cavity 101 through the mounting opening 102, and a gap is formed between the filter screen 2 and the air duct 1;

[0026] The gasket 3 is sleeved on the circumference of the filter screen 2 to seal the gap.

[0027] In this embodiment, a ventilation cavity 101 is formed inside the air duct 1 along its length direction for air circulation. A mounting port 102 is also provided on one side of the air duct 1. The mounting port 102 is connected to the ventilation cavity 101. A gap is formed between the filter 2 and the air duct 1, which facilitates the installation and removal of the filter 2. The filter 2 slides into the ventilation cavity 101 through the mounting port 102. The filter 2 can be easily inserted or removed for easy cleaning or replacement. This sliding installation method simplifies the maintenance process and improves efficiency. In order to ensure that the gap between the ventilation cavity 101 and the filter 2 can be effectively sealed and prevent dust or impurities from bypassing the filter 2 and directly entering the ventilation cavity 101, a gasket 3 is provided on the circumferential surface of the filter 2, and the gasket 3 is in close contact with the inner wall of the air duct 1, thereby achieving a good sealing effect; furthermore, the gasket 3 can also be used to compensate for the installation gap between the filter 2 and the air duct 1, thereby avoiding the problem of intermittent abnormal noise between the filter 2 and the air duct 1 due to unstable wind pressure caused by other factors such as unstable motor voltage of the wind source equipment when the air is supplied by the air duct 1.

[0028] The ventilation cavity 101 is provided with a slot 103 , and the gasket 3 is disposed in the slot 103 .

[0029] In this embodiment, a slot 103 is additionally provided inside the ventilation cavity 101 in order to better fix the gasket 3 and prevent the gasket 3 from being displaced under the impact of airflow. The gasket 3 is not only sleeved on the circumferential surface of the filter 2, but its outer edge is also embedded in the slot 103 in the ventilation cavity 101, so that the gasket 3 can be more firmly fixed in the designated position. At the same time, the close fit between the slot 103 and the gasket 3 further enhances the sealing performance, effectively preventing unfiltered air or impurities from bypassing the filter 2 and directly entering the ventilation cavity 101.

[0030] The material of the pad 3 is a compressible material.

[0031] In this embodiment, the compressible material (such as rubber, silicone) has good elasticity and can be deformed under the action of external force to fill the gap between the filter 2 and the air duct 1, thereby providing an excellent sealing effect. When the gasket 3 is pressed between the filter 2 and the air duct 1, it can effectively close the tiny gap and prevent unfiltered air or impurities from bypassing the filter 2 and entering the ventilation cavity 101. The compressible material can also absorb some vibration and noise, and can reduce the noise during equipment operation. The compressible gasket 3 can effectively reduce the vibration and noise caused by airflow and improve the working environment.

[0032] The gasket 3 is provided with a mounting groove 301 , and the filter screen 2 is clamped in the mounting groove 301 .

[0033] In this embodiment, a mounting groove 301 is provided on the gasket 3, so that the filter 2 can be precisely inserted therein, thereby ensuring the accurate position of the filter 2 in the ventilation cavity 101 and avoiding the movement or vibration of the filter 2 under the action of the airflow. The filter 2 is tightly combined with the mounting groove 301 on the gasket 3, further enhancing the sealing performance of the entire gasket 3. The filter 2 is inserted into the mounting groove 301, which not only ensures that the gap between the filter 2 and the air duct 1 is completely closed, but also reduces the possibility of air passing directly without passing through the filter 2, thereby improving the filtering efficiency.

[0034] The installation opening 102 is detachably provided with a sealing plate 4 for blocking or opening the installation opening 102 . When the sealing plate 4 blocks the installation opening 102 , the sealing plate 4 abuts against the gasket 3 .

[0035] In this embodiment, by providing a detachable sealing plate 4, the user can block or open the installation port 102 at any time according to actual needs, allowing the filter 2 to be quickly installed and removed. When the sealing plate 4 blocks the installation port 102, it abuts against the gasket 3 to form a double sealing barrier and limit guarantee, further preventing abnormal noise from occurring between the filter 2 and the air duct 1.

[0036] The sealing plate 4 is fixed to the mounting opening 102 by screws.

[0037] In this embodiment, screw fixing provides a strong and reliable connection method, ensuring the stability and sealing of the sealing plate 4 when sealing the installation port 102. During the installation or disassembly process, the contact pressure between the sealing plate 4 and the gasket 3 can be fine-tuned by tightening or loosening the screws to achieve the best sealing effect.

[0038] A positioning groove 5 is formed at one end of the sealing plate 4 facing the installation opening 102 , so as to allow a portion of the gasket 3 to extend into the positioning groove 5 .

[0039] In this embodiment, the positioning groove 5 is designed to allow the gasket 3 to partially extend therein, forming an additional sealing layer. When the sealing plate 4 blocks the installation opening 102, the close contact between the gasket 3 and the positioning groove 5 can effectively prevent air from leaking from the junction of the sealing plate 4 and the gasket 3, thereby significantly improving the sealing performance. The cooperation between the positioning groove 5 and the gasket 3 not only enhances the sealing performance, but also helps to increase the structural stability of the sealing plate 4. After the gasket 3 extends into the positioning groove 5, it can play a certain supporting and limiting role, preventing the sealing plate 4 from being deformed or displaced under airflow impact or long-term use.

[0040] This embodiment also proposes a central air conditioner, which includes the installation structure of the air duct 1 and the filter 2 mentioned above. The specific structure of the central air conditioner refers to the above embodiment. Since this central air conditioner adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
