Description

Technical Field

[0001] This application relates to the field of curtain wall ventilation technology, specifically a curtain wall ventilation structure. Background Technology

[0002] With the rapid development of the modern construction industry, glass curtain walls have been widely used in various high-rise buildings due to their beauty and transparency. Ventilated curtain walls, as a new type of curtain wall that combines energy saving and ventilation, retain the advantages of traditional glass curtain walls while achieving orderly exchange of air inside and outside the building through a rationally designed airflow channel.

[0003] For example, patent CN222295395U discloses a ventilated curtain wall structure, which includes: a curtain wall body, a frame, a cleaning brush, baffles, a worm gear, and a worm wheel. This invention, by setting several baffles, can adjust the ventilation rate and is suitable for different weather conditions.

[0004] In the aforementioned patented ventilated curtain wall structure, the baffle is located inside the frame. To observe its opening and closing range, the cover plate must be opened and the screen must be viewed, making it inconvenient for users to visually judge the ventilation level. Furthermore, in terms of dust prevention and cleaning, it relies solely on a cleaning brush fixed above the screen, which is pulled to clean the screen. This cleaning method is relatively simple and cannot thoroughly remove tightly attached or complex dirt, easily causing the screen mesh to become clogged. During long-term use, the cleaning brush will also accumulate a certain amount of dust and impurities on its surface, further affecting the cleaning effect on the screen and increasing the possibility of screen mesh clogging. Therefore, it is necessary to provide a curtain wall ventilation structure to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved in this application is to provide a curtain wall ventilation structure to solve the problems in the above-mentioned patents, such as the inconvenience of intuitively judging the opening and closing range of the baffle, the single cleaning method of the mesh panel leading to incomplete cleaning, and the easy adhesion of impurities to the cleaning brush, which affects the cleaning effect and easily causes mesh blockage.

[0007] The technical solution adopted by this application to solve its technical problem is: a curtain wall ventilation structure, comprising:

[0008] The curtain wall body has a ventilation box installed at its lower end, an exhaust plate installed on one side of the ventilation box, and multiple exhaust holes provided on the exhaust plate.

[0009] A wind speed regulating component is installed inside the ventilation box. The wind speed regulating component includes a bidirectional lead screw rotatably connected inside the ventilation box. Two sliders are sleeved on the shaft of the bidirectional lead screw. An intermediate plate is installed on each slider. A baffle plate adapted to the exhaust hole is installed on each intermediate plate.

[0010] A filter assembly is installed inside the ventilation box. The filter assembly includes a filter frame that slides inside the ventilation box. Each side of the filter frame is provided with a limiting groove. An adapter plate slides in each limiting groove. A cleaning brush plate is installed on the adapter plate. A filter screen plate adapted to the cleaning brush plate is installed inside the filter frame.

[0011] Furthermore, the baffle plate is tightly fitted to the exhaust plate and is adapted to block the exhaust hole.

[0012] Furthermore, two guide rods are installed at each end of the ventilation box, and guide sleeves that can slide along the axial direction of the guide rods are installed on the wind baffle.

[0013] Furthermore, the cleaning brush plate is equipped with multiple brushes.

[0014] Furthermore, the upper part of the adapter plate penetrates through the filter frame and extends to the outside of the ventilation box, where a connecting rod is installed.

[0015] Furthermore, a second handle is installed on the connecting rod.

[0016] Furthermore, the exhaust plate is made of aluminum alloy.

[0017] The beneficial effects of this application are as follows: The curtain wall ventilation structure provided by this application can flexibly adjust the degree of obstruction of the exhaust hole by the wind baffle through the setting of the slider, intermediate plate and wind baffle in the wind speed adjustment component, so as to achieve precise control of ventilation volume and intuitively see the adjustment status. This solves the problem of difficulty in judging the opening and closing of traditional baffles. At the same time, in the filter component, the cleaning brush can be driven by the adapter plate to effectively clean the filter screen, solving the problem of the traditional cleaning method being relatively simple and easy to clog the filter screen.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] like Figure 1 and 2As shown, this application provides a curtain wall ventilation structure, including a curtain wall body 1. The curtain wall body 1 is the basic frame of the entire curtain wall ventilation structure, which plays the role of supporting and installing other components. It is the main part of the curtain wall structure. A ventilation box 2 is fixedly installed at the lower end of the curtain wall body 1. The ventilation box 2 provides a special channel for the circulation of air in the curtain wall structure, so that air can enter from the outside and flow into the room in an orderly manner. It is a space for air exchange.

[0032] An air inlet plate 21 is bolted to the other side of the ventilation box 2. Multiple air inlet holes 211 are spaced apart on the air inlet plate 21. These air inlet holes 211 are the entrances for outside air to enter the ventilation box 2. An exhaust plate 22 is bolted to one side of the ventilation box 2. Multiple exhaust holes 221 are spaced apart on the exhaust plate 22. These exhaust holes 221 are the exits for air inside the ventilation box 2 to enter the room. Air enters the room through these holes to complete the ventilation process. The multiple air inlet holes 211 and the multiple exhaust holes 221 are interconnected.

[0033] like Figure 3 and Figure 4 As shown, a wind speed regulating component 3 is installed inside the ventilation box 2. This component is used to regulate the ventilation volume of air entering the room through the exhaust hole 221. The wind speed regulating component 3 includes a bidirectional lead screw 31 rotatably connected to one side of the ventilation box 2. One end of the bidirectional lead screw 31 passes through the ventilation box 2 and is fixedly mounted with an adjusting knob (not shown in the figure). The user can rotate the bidirectional lead screw 31 by rotating the adjusting knob, which is the driving component for adjusting the windshield position. Two sliders 32 are threadedly connected to the body of the bidirectional lead screw 31, and a middle slider is fixedly mounted on each slider 32. A baffle plate 34 is fixedly installed on one side of the middle plate 33. The baffle plate 34 is tightly attached to the exhaust plate 22 and is suitable for blocking the exhaust hole 221. The rotation of the bidirectional screw 31 drives the two sliders 32 threaded to it to move in opposite directions or away from each other. The power is then transmitted through the middle plate 33 to make the baffle plate 34 move synchronously, thereby adjusting the degree of blocking of the exhaust hole 221 on the exhaust plate 22 and ultimately controlling the amount of ventilation. At the same time, the position of the baffle plate 34 can be observed through the exhaust hole 221, thereby intuitively reflecting the degree of ventilation.

[0034] Two guide rods 35 are fixedly installed at both ends inside the ventilation box 2. Guide sleeves 36 that can slide along the axial direction of the guide rods 35 are fixedly installed on the baffle plate 34. The guide rods 35 provide a track for the sliding of the guide sleeves 36, and play a guiding and limiting role in the movement of the baffle plate 34 to prevent it from deviating.

[0035] like Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, a filter assembly 4 is installed inside the ventilation box 2. The filter assembly 4 filters the air entering the ventilation box 2, intercepts and reduces impurities in the air, such as dust and insects. At the same time, the filter components can be easily cleaned through an operable cleaning structure to prevent clogging and ensure smooth ventilation and cleanliness of the indoor air. This solves the problem of incomplete cleaning and easy clogging of the screen in traditional structures. The filter assembly 4 includes a filter frame 41 that slides inside the ventilation box 2. The filter frame 41 provides an installation and support frame for the components of the filter assembly 4 and is the basic structure of the filter assembly 4.

[0036] Limiting grooves 42 are provided on both sides of the filter frame 41, and a transition plate 43 slides in each limiting groove 42. The limiting groove 42 provides a track for the sliding of the transition plate 43 and restricts the movement direction of the transition plate 43. A cleaning brush plate 44 is fixedly installed at the lower end of each transition plate 43. Multiple brushes (not marked in the figure) are fixedly installed on the cleaning brush plate 44. The multiple brushes on the cleaning brush plate 44 are used to clean the dust attached to the surface of the filter plate and ensure the filtration effect of the filter plate.

[0037] The upper part of the adapter plate 43 passes through the filter frame 41 and extends to the outside of the ventilation box 2, where a connecting rod 45 is fixedly installed. A second handle 48 is fixedly installed in the center of the connecting rod 45, and a first handle 47 is fixedly installed in the center of the upper end of the filter frame 41. A detachable filter screen 46 is installed inside the filter frame 41. The filter screen 46 filters the air entering the ventilation box 2, blocking dust and other impurities from entering the room. The detachable design facilitates cleaning and replacement. Specifically, the filter frame 41 can be pulled out of the ventilation box 2 through the first handle 47, which facilitates the overall maintenance of the filter assembly 4. By holding the second handle 48, the connecting rod 45, the adapter plate 43, and the cleaning brush plate 44 at the lower end can be moved to clean the filter screen 46. This solves the problem of the single cleaning method in the traditional structure and improves the cleaning effect of the filter assembly 4.

[0038] Working principle: When ventilation is required, outside air first enters the ventilation box 2 through the air inlet 211 on the air inlet plate 21. The incoming air first passes through the filter plate 46 in the filter assembly 4. The filter plate 46 filters the air, and the filtered clean air continues to flow in the ventilation box 2.

[0039] If the ventilation volume needs to be adjusted, the user can rotate the adjustment knob at the end of the bidirectional lead screw 31. When the bidirectional lead screw 31 is rotated, the two sliders 32 connected to it will move in opposite directions or away from each other along the lead screw. The sliders 32 drive the baffle 34 to move synchronously through the intermediate plate 33. The baffle 34 moves smoothly under the guidance and limiting action of the guide rod 35 and the guide sleeve 36, changing the degree of obstruction of the exhaust holes 221 on the exhaust plate 22. When the baffles 34 are close to each other, the number of blocked exhaust holes 221 increases and the ventilation volume decreases; when the baffles 34 are far apart, the number of blocked exhaust holes 221 decreases and the ventilation volume increases. The filtered air enters the room through the adjusted exhaust holes 221, completing the ventilation process.

[0040] When a lot of dust adheres to the surface of the filter screen 46, affecting ventilation, the user can hold the second handle 48 and move it up and down. The second handle 48 drives the connecting rod 45 to move, and the connecting rod 45 drives the adapter plate 43 to slide up and down along the limiting grooves 42 on both sides of the filter frame 41. The cleaning brush plate 44 at the lower end of the adapter plate 43 moves synchronously. The brush on the cleaning brush plate 44 will wipe the surface of the filter screen 46 to remove the dust and reduce the occurrence of mesh blockage. If the filter screen 46 needs to be thoroughly cleaned or replaced, the filter frame 41 can be pulled out of the ventilation box 2 through the first handle 47. After cleaning the filter screen 46, the filter frame 41 can be slid back into the ventilation box 2 for continued use.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
