Description

Technical Field

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

[0002] Ventilation ducts are a system of pipes used to transport air, regulate indoor air quality, and control temperature and humidity. They are usually installed inside or outside a building as part of the building's ventilation and air conditioning system. Ventilation ducts can improve the indoor environment by transporting fresh air, removing stale air, controlling air circulation, and distributing heat. The air entering the ventilation system may carry tiny particles such as dust, fine particles, and flying dust. These particles may be deposited at the entrance of the ventilation duct during air flow. If the entrance of the ventilation system is exposed to the outdoors and the ambient humidity is high, the moisture may cause the deposition of dirt. Moisture makes it easier for particles in the air to adhere to the walls of the duct. The dirt may contain organic matter, bacteria, mold, etc., which will release bad odors when they accumulate and decompose on the ventilation duct. The accumulation of dirt may hinder air circulation and reduce the efficiency of the ventilation system.

[0003] In summary, there is a problem of dirt accumulation and odor generation at the entrance of the existing ventilation duct. Utility Model Content

[0004] In view of this, the utility model provides a ventilation duct inlet dust cleaning device, which can solve the problem of dirt accumulation and odor generation at the inlet of the existing ventilation duct.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a dust cleaning device for the inlet of a ventilation duct, comprising an air duct, wherein the air duct is provided with an air outlet, and the air duct is used to transport air into a room, wherein a slide groove and a cleaning device are provided inside the air duct, the slide groove is slidably connected to the cleaning device, the slide groove is used to drive the cleaning device to move inside the air duct, and the cleaning device is used to clean the inner wall of the air duct.

[0007] The technical effects of a dust cleaning device for a ventilation duct inlet provided by the utility model are as follows: by setting up an air duct, it is possible to ensure sufficient circulation of air inside and outside the building by conveying air, thereby maintaining the freshness of the indoor air; by setting up a slide groove, it is possible to guide the cleaning device to move along a fixed path on the inner wall of the air duct, ensuring that the dirt attached to the inner wall of the air duct on this path can be cleaned off, and at the same time, the slide groove can ensure that the cleaning device can move smoothly inside the air duct, thereby improving the cleaning efficiency; by setting up a cleaning device, it is possible to physically clean the dirt on the inner wall of the air duct, which helps to maintain the smoothness and normal operation of the air duct, and can also prevent the accumulation of dirt and reduce the occurrence of odor; by setting up a metal block and a magnetic ring, the position of the cleaning device can be limited, so that it can be fixed at the same position for a long time, thereby achieving precise cleaning.

[0008] On the basis of the above technical solution, the dust cleaning device for the ventilation duct inlet of the utility model can also be improved as follows:

[0009] Wherein, the cleaning device comprises a slider and a spring, the slider is adapted to the slide groove, one end of the spring is fixedly connected to the slider, and a metal block is fixedly connected to the top of the slider.

[0010] The beneficial effect of adopting the above-mentioned improvement scheme is: by setting a spring, the first brush or the second brush can swing back and forth inside the air duct, so that the cleaning range is expanded to cover a wider area. At the same time, the spring can shake under the push of wind, which can reduce the waste of resources.

[0011] Furthermore, the other end of the spring is fixedly connected to the first brush, and the first brush is a long strip structure.

[0012] The beneficial effect of adopting the above-mentioned improvement scheme is that by providing the first brush, the lower bottom surface of the inner wall of the air duct can be cleaned, which helps to remove the dirt accumulated on the lower bottom surface.

[0013] Furthermore, the length of the first brush is the same as the diameter of the inner wall of the air duct.

[0014] Furthermore, the other end of the spring is fixedly connected to a ventilation sheet, the ventilation sheet is a circular ring structure, and a second brush is fixedly connected to the outer ring of the ventilation sheet.

[0015] The beneficial effect of adopting the above-mentioned improvement scheme is that by providing the ventilation sheet and the second brush, the inner wall of the entire air duct can be cleaned, thereby expanding the cleaning range and reducing the probability of odor occurrence.

[0016] Furthermore, the size of the ventilation sheet is smaller than the size of the inner wall of the air duct, and the overall diameter of the ventilation sheet and the second brush is the same as the diameter of the inner wall of the air duct.

[0017] Furthermore, the slider is a letter T-shaped structure.

[0018] The beneficial effect of adopting the above-mentioned improvement scheme is that by setting the shape of the sliding block to be a letter T, the cleaning device can be prevented from falling off from the sliding groove.

[0019] Furthermore, a magnet ring is detachably connected to the outer wall of the air duct, and the magnet ring is a semicircular ring structure.

[0020] The beneficial effect of adopting the above-mentioned improvement scheme is that by providing the magnet ring, it can fit the shape of the air duct and prevent the magnet ring from falling off.

[0021] Furthermore, the curvature of the magnet ring is the same as the curvature of the outer wall of the air duct, and the length of the straight-line distance between the two ends of the magnet ring is 3 / 4 of the diameter of the air duct.

[0022] Furthermore, the air duct is made of plastic.

[0023] Compared with the prior art, the beneficial effects of the dust cleaning device at the inlet of the ventilation duct provided by the utility model are as follows: by setting up the air duct, it is possible to ensure sufficient circulation of air inside and outside the building by conveying air, thereby maintaining the freshness of the indoor air; by setting up the slide groove, it is possible to guide the cleaning device to move along a fixed path on the inner wall of the air duct, ensuring that the dirt attached to the inner wall of the air duct on this path can be cleaned off, and at the same time, the slide groove can ensure that the cleaning device can move smoothly inside the air duct, thereby improving the cleaning efficiency; by setting up the cleaning device, the dirt on the inner wall of the air duct can be cleaned in a physical manner, which helps to maintain the smoothness and normal operation of the air duct, and can also prevent the accumulation of dirt and reduce the occurrence of odor; by setting up the metal block and the magnetic ring, the position of the cleaning device can be limited, so that it can be fixed in the same position for a long time, thereby achieving precise cleaning.
