[0002] Due to building ventilation and energy-saving requirements, opening windows are often set on building curtain walls for ventilation. Opening windows have a large effective ventilation area, but the setting of opening windows, especially after the windows are opened, makes the building facade messy, which has a great impact on the appearance of the building. The setting of opening windows also greatly increases the cost and also affects the safe use of the curtain wall. Therefore, most of the curtain wall ventilators on the market are used to achieve curtain wall ventilation. Curtain wall ventilators are an additional device (supporting product) of the curtain wall. Their function is to replace the traditional window ventilation method for air exchange. Compared with other types of ventilators, they also have sound insulation, heat insulation, wind and rainproof and other properties. They are installed and used in conjunction with the curtain wall, have a switch that can be opened and closed, and are used in places where people are active indoors.

[0003] When the curtain wall ventilator is in use, a filter element is installed inside it to prevent external dust from entering the room. After a period of use, the filter element needs to be replaced. However, after opening the outer cover of the curtain wall ventilator, the curtain wall ventilator and the external ventilation are not cut off. Therefore, when the filter element is replaced, the external airflow still blows inward, which will cause the dust on the filter element to be pushed and scattered into the indoor air, which is not conducive to maintaining the indoor air quality. Based on this, a new type of hidden ventilation dust collector for building curtain walls is provided. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 In the embodiment of the utility model, a novel building curtain wall hidden ventilation dust collector comprises a ventilation assembly 1 having a shell 101, a cover plate 102, a filter element 103, and an air inlet 104. The cover plate 102 is rotatably connected to one end of the shell 101, and the air inlet 104 is provided at the other end of the shell 101. The filter element 103 is installed on the inner side of the shell 101. A blocking seat 3 for blocking the air inlet 104 is provided on the inner side of the shell 101. Concave grooves 2 are provided at the upper and lower ends of the inner wall of the shell 101. A linkage assembly 4 connected to the cover plate 102 and the blocking seat 3 is provided on the inner side of the concave groove 2. The linkage assembly 4 is used to transmit the power of rotating the cover plate 102 to the blocking seat 3 to realize the blocking and unblocking of the concave groove 2 by the blocking seat 3.

[0023] The linkage assembly 4 includes a Z-shaped slider 401, a moving block 402, a moving column 403, a guide rail 404, a fixed block 405 and a linkage rod 406;

[0024] The Z-shaped slider 401 is slidably connected to the inner side of the concave groove 2, and one end of the Z-shaped slider 401 extends to the inner side of the housing 101 and is fixedly connected to the blocking seat 3. The moving block 402 is distributed at the bottom of the other end of the Z-shaped slider 401 and is slidably connected to the inner side of the concave groove 2. The moving column 403 is fixed to the top of the moving block 402 and extends to the inner side of the Z-shaped slider 401. The guide rail groove 404 is opened at the position where the Z-shaped slider 401 contacts the moving column 403, and the moving column 403 and the guide rail groove 404 are in a slidably connected state.

[0025] The fixed block 405 is fixed to one end surface of the cover plate 102 close to the housing 101, the linkage rod 406 is located between the fixed block 405 and the moving block 402, and the two ends of the linkage rod 406 are rotatably connected to the top of the fixed block 405 and the bottom of the moving block 402 respectively;

[0026] The top view cross section of the guide groove 404 is in an inclined state, and the end of the guide groove 404 facing the center line of the Z-shaped slider 401 is away from the cover plate 102, and the other end of the guide groove 404 is close to the cover plate 102;

[0027] The sealing seat 3 is composed of a plurality of conical plugs and a rectangular frame. The number of the conical plugs matches the number of the air inlet holes 104 and the positions correspond one to one. The rectangular frame connects the plurality of conical plugs into a whole. The Z-shaped slider 401 is fixedly connected to the rectangular frame.

[0028] In this embodiment, it should be noted that: a ventilation hole for airflow is provided inside the cover plate 102, and the external air enters the housing 101 through the air inlet 104, and is filtered by the filter element 103, and finally enters the room through the ventilation hole, thus ensuring indoor ventilation and dust prevention (it should be noted that: at this time, the blocking seat 3 and the air inlet 104 are separated);

[0029] When the filter element 103 needs to be replaced, the cover plate 102 is opened. When the cover plate 102 is rotated and opened, the linkage rod 406 can be pulled by the fixed block 405. The linkage rod 406 will pull the moving block 402, so that the moving block 402 moves toward the inner wall of the shell 101. The moving block 402 will drive the moving column 403 to move along the inner wall track of the guide rail groove 404. Since the moving track of the moving column 403 is a straight line, and the track of the guide rail groove 404 is an oblique line, the moving column 403 will squeeze the inner wall of the moving rail groove 404 during this process, so that Z The Z-shaped slider 401 moves horizontally, and the moving direction of the Z-shaped slider 401 is perpendicular to the moving direction of the moving block 402. The Z-shaped slider 401 will push the blocking seat 3 to move toward the air inlet 104, and finally the sealing block on the blocking seat 3 will completely block the air inlet 104. In this way, when the cover 102 is opened, the air inlet 104 is blocked, so that the external airflow cannot enter the shell 101. At this time, the filter element 103 can be replaced without being affected by the external airflow. The replacement of the filter element 103 is more convenient and will not cause dust to be scattered.

[0030] Please refer to Figures 3-4 The outer walls of the moving block 402 are formed with limiting blocks at both ends, and the inner side of the concave groove 2 is provided with limiting grooves for the limiting blocks to slide in a limited manner.

[0031] In this embodiment: this structure can realize the limited movement of the moving block 402 so that it will not fall off.

[0032] Please refer to Figures 2 to 4 The width of the vertical groove where the concave groove 2 contacts the bent portion of the Z-shaped slider 401 is greater than the thickness of the bent portion of the Z-shaped slider 401, and the width of the transverse groove at the top of the concave groove 2 is greater than the width of the straight edge at the top of the Z-shaped slider 401, so as to provide space for the horizontal movement of the Z-shaped slider 401;

[0033] The linkage components 4 are symmetrically arranged in two groups, which are used to improve the operating stability of the device.

[0034] In this embodiment: the concave groove 2 can provide space and limit for the movement of the Z-shaped slider 401, and the upper and lower groups of linkage components 4 are set up to make the movement of the blocking seat 3 synchronized up and down, thereby realizing the synchronous blocking operation of the air inlet 104.
