Description

Technical Field

[0001] The utility model belongs to the technical field of air duct cleaning, and in particular relates to a ventilation duct opening cleaning device. Background Art

[0002] Ventilation ducts are systems used to ventilate buildings or other enclosed spaces. They are typically made of metal, plastic, or other durable materials. With the acceleration of urbanization and industrialization, air pollution has become a serious problem, and the importance of ventilation ducts has become increasingly prominent. By introducing fresh air, ventilation ducts effectively reduce the concentration of harmful substances such as carbon dioxide and formaldehyde indoors, thereby ensuring the comfort and health of people in offices, homes, and public spaces. Ventilation ducts not only help regulate air humidity but also expel hot air in the summer and maintain a comfortable indoor temperature in the winter. This regulation not only improves people's quality of life but also contributes to energy conservation and emission reduction, in line with the concept of sustainable development. A well-functioning ventilation system helps prevent moisture and mold, extend the life of building structures, and reduce repair and maintenance costs.

[0003] However, even filtered air can still contain tiny dust particles. These particles are carried into ventilation ducts by the airflow and can accumulate near the duct openings over time. Static electricity can affect the duct walls or duct openings, attracting fine airborne particles to the surface, eventually leading to the formation of a dust layer. This can affect indoor air quality, increase the concentration of airborne pollutants, and significantly impact the health of residents and workers.

[0004] In summary, existing ventilation ducts have the problem of easy accumulation of dust. Utility Model Content

[0005] In view of this, the utility model provides a ventilation duct opening cleaning device, which can solve the problem that dust is easily deposited in the existing ventilation duct.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a ventilation duct opening cleaning device, comprising an air duct opening, wherein the air duct opening is used to exhaust air into the room, wherein a baffle is provided on the air duct opening, and the baffle is detachably connected to the air duct opening, and a plurality of cross-shaped air outlets are provided on the baffle, and the air outlets are used to accelerate the flow rate of air, and a cleaning component is detachably connected to the air outlet, and the cleaning component is used to clean dust deposited on the air outlet.

[0008] The technical effects of a ventilation duct cleaning device provided by the present invention are as follows: by setting air outlets, the Venturi principle can be fully utilized. When the outlet area of ​​the fluid is reduced, the speed of the fluid passing through these air outlets will increase. Increasing the flow rate can discharge air faster to facilitate rapid ventilation and promote the entry of fresh air, thereby improving the ventilation efficiency of indoor and outdoor air; at the same time, high-speed air outlet can more effectively take away heat, thereby improving the cooling effect and making the indoor environment cooler and more pleasant; the setting of multiple air outlets can reduce the noise and vibration that may be generated when the fluid flows out, because when the fluid exits from multiple small holes, its dispersion performance is better and it is not easy to cause obvious eddies and turbulence. By setting a cleaning component, the dust accumulated at the air outlet can be cleaned, thereby ensuring the restoration of normal ventilation effect and the smooth flow of air. Cleaning can reduce the corrosion or damage of dust and impurities to the internal parts of the equipment, extend the service life of the equipment, and reduce maintenance costs.

[0009] On the basis of the above technical solution, the ventilation duct opening cleaning device of the present invention can also be improved as follows:

[0011] The benefits of this improved solution include: By providing a cross-shaped air outlet, air can be evenly distributed in four directions, effectively maintaining a balanced temperature and humidity within the space. Cross-shaped air outlets are often elegantly designed, making them more attractive. They also reduce pressure loss and noise levels during airflow, improving user comfort.

[0012] Furthermore, the first air outlet channel and the second air outlet channel have the same size and structure, and the first air outlet channel and the second air outlet channel are surrounded by the metal strip, and the metal strip is fixedly connected to the baffle. The metal strip is a circular structure, and the center of the metal strip is the midpoint of the first air outlet channel and the second air outlet channel. The diameter of the metal strip is greater than the length of the first air outlet channel.

[0013] Furthermore, the cleaning assembly includes a cover body, a magnet, a first connecting rod, a second connecting rod, a fixing piece, a first wiping head and a second wiping head, a circle of the magnets is fixedly connected to the lower bottom surface of the cover body, one end of the second connecting rod is fixedly connected to the upper top surface of the fixing piece, the other end of the second connecting rod passes through one end of the lower bottom surface of the first connecting rod and extends to the outside of the first connecting rod, the first connecting rod and the second connecting rod are rotatably connected, the first wiping head and the second wiping head are respectively fixedly connected to the two ends of the fixing piece, the first connecting rod passes through the midpoint of the cover body and extends to the interior of the cover body, and the cover body is rotatably connected to the first connecting rod.

[0014] The beneficial effect of adopting the above-mentioned improvement scheme is that by providing a magnet, it is possible to avoid relative sliding between the cover and the baffle of the first wiping head and the second wiping head during operation, which may result in inadequate cleaning.

[0015] Furthermore, the magnet is adapted to the metal bar.

[0016] Furthermore, the first wiping head and the second wiping head are adapted to the first air outlet channel and the second air outlet channel.

[0017] Furthermore, the connection point between the second connecting rod and the fixing member is the midpoint of the fixing member.

[0018] Furthermore, the first connecting rod is an L-shaped structure, and the length of the lower half of the first connecting rod is half the length of the fixing member.

[0019] Furthermore, a rocker is fixedly connected to one end of the first connecting rod located on the outside of the cover body.

[0020] The beneficial effect of adopting the above-mentioned improvement scheme is that the air outlet can be cleaned manually, which helps to control the intensity of cleaning.

[0021] Furthermore, one end of the first connecting rod located outside the cover body is fixedly connected to the output end of the motor.

[0022] The beneficial effects of adopting the above-mentioned improvement scheme are: the air outlet can be cleaned by means of a motor, which improves the efficiency and convenience of cleaning and reduces labor costs and working time.

[0023] Compared with the prior art, the beneficial effects of the ventilation duct cleaning device provided by the present invention are as follows: by setting the air outlet, the Venturi principle can be fully utilized. When the outlet area of ​​the fluid is reduced, the speed of the fluid passing through these air outlets will increase. Increasing the flow rate can discharge the air faster to facilitate rapid ventilation and promote the entry of fresh air, thereby improving the ventilation efficiency of indoor and outdoor air. At the same time, high-speed air outlet can more effectively take away heat, thereby improving the cooling effect and making the room cooler and more pleasant. The setting of multiple air outlets can reduce the noise and vibration that may be generated when the fluid flows out, because when the fluid exits from multiple small holes, its dispersion performance is better and it is not easy to cause obvious eddies and turbulence. By setting a cleaning component, the dust accumulated at the air outlet can be cleaned, thereby ensuring the restoration of normal ventilation effect and the smooth flow of air. Cleaning can reduce the corrosion or damage of dust and impurities to the internal parts of the equipment, extend the service life of the equipment, and reduce maintenance costs.

The metal strip 123 is a circular structure, and the center of the metal strip 123 is the midpoint of the first air outlet channel 121 and the second air outlet channel 122. The diameter of the metal strip 123 is greater than the length of the first air outlet channel 121.

[0035] Furthermore, in the above technical solution, the cleaning assembly 13 includes a cover body 131, a magnet 132, a first connecting rod 133, a second connecting rod 134, a fixing member 135, a first wiping head 136 and a second wiping head 137.

The first wiper 136 and the second wiper 137 are respectively inserted into the first air outlet channel 121 and the second air outlet channel 122. When the first wiper 136 and the second wiper 137 are fully inserted into the air outlet 12, the bottom surface of the cover 131 is exactly in contact with the baffle 11. The position of the cover 131 is adjusted so that the magnet 132 and the metal strip 123 completely overlap.
