Description

Technical Field

[0001] This utility model relates to the field of dust suppression technology, specifically a ventilation and dust suppression device for indoor decoration. Background Technology

[0002] In the field of interior decoration, dust has always been a major problem that plagues construction workers, residents and the environment. From a health perspective, harmful substances in dust can threaten human health. From an environmental perspective, it not only pollutes the indoor and outdoor environment but also affects air quality. From a construction perspective, dust can reduce construction efficiency and increase construction costs. Against this backdrop, ventilation and dust reduction technology for interior decoration has emerged, and its development process is closely linked to the current predicament.

[0003] Relying on the pores of filter media to intercept dust, the high concentration and uneven particle size of decoration dust can easily clog the pores of the filter media, resulting in reduced dust removal efficiency and the need for frequent filter media replacement. This not only increases the cost of consumables, but also causes the dust attached to the filter media to fall off during the replacement process, causing secondary pollution. To address this, we propose a ventilation and dust suppression device for indoor decoration. Utility Model Content

[0004] The purpose of this utility model is to provide a ventilation and dust suppression device for indoor decoration.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ventilation and dust removal device for indoor decoration, comprising a mobile box, wherein the interior of the mobile box is provided with a ventilation component and a dust removal component;

[0006] The dust removal assembly includes a water tank, a dust collection box, a positioning plate, an air inlet pipe, and a connecting box. The side of the dust collection box is rotatably connected to the inside of the water tank, and the inner wall of the dust collection box is rotatably connected to the side of the positioning plate. The two ends of the air inlet pipe are respectively connected to the positioning plate and the inner wall of the water tank, and the side of the connecting box is connected to the side of the water tank.

[0007] The ventilation assembly includes an electric fan, a dust collection bucket, and a connecting pipe. One end of the dust collection bucket is connected to the interior of the connecting box, and one end of the connecting pipe is connected to the air inlet of the electric fan.

[0008] As a further embodiment of this utility model: a servo motor is connected to the lower end face of the mobile box, and the output end of the servo motor passes through the inner wall of the water tank and is connected to the center of the lower end face of the dust removal box.

[0009] As a further embodiment of this utility model: one end of the air inlet pipe is connected to the inside of the connecting box, and the other end of the air inlet pipe is connected to the inside of the dust removal box.

[0010] As a further embodiment of this utility model: the side of the electric fan is connected to the inner wall of the mobile box, and the side of the dust collection hopper is connected to the inner wall of the mobile box.

[0011] As a further embodiment of this utility model, the lower end face of the dust collector is provided with a through hole.

[0012] As a further embodiment of this utility model: a drain pipe is provided on the lower end face of the water tank, and a water filling pipe is provided on the side of the water tank. Both the drain pipe and the water filling pipe are sealed with sealing caps on their sides.

[0013] As a further embodiment of this utility model: the other end of the connecting pipe is connected to the interior of the water tank.

[0014] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0015] 1. This utility model uses a servo motor to drive the dust collection box to rotate, which generates centrifugal force in the dust-laden air entering the dust collection box. The denser dust particles are thrown against the inner wall of the dust collection box, and then come into full contact with the clean water in the water tank and are adsorbed. At the same time, the through hole at the bottom of the dust collection box allows the wastewater that has adsorbed the dust to flow back to the water tank, preventing the dust from being stirred up again. Compared with a single filtration method, this dual dust collection design can separate dust in the air more efficiently, especially for particles such as cement dust and wood dust commonly found in decoration, and the purification effect is more stable.

[0016] 2. This utility model uses an electric fan in the ventilation component to create negative pressure, which can not only actively draw in dusty air for purification, but also drive indoor air circulation. The purified air can flow back into the room or be exhausted outdoors. This solves the problem of excessive dust during decoration and improves the current situation of poor air circulation and strong odor, thus meeting the dual needs of ventilation and dust control in the decoration environment.

[0017] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0026] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Please see the appendix Figure 1 -Appendix Figure 6 The present invention provides a ventilation and dust removal device for indoor decoration, comprising a mobile box 1, wherein a ventilation component 2 and a dust removal component 3 are provided inside the mobile box 1;

[0028] In embodiment 1, the dust removal assembly 3 includes a water tank 31, a dust collection box 33, a positioning plate 34, an air inlet pipe 35, and a connecting box 36. The side of the dust collection box 33 is rotatably connected to the inside of the water tank 31, and the inner wall of the dust collection box 33 is rotatably connected to the side of the positioning plate 34. Both ends of the air inlet pipe 35 are respectively connected to the positioning plate 34 and the inner wall of the water tank 31. The side of the connecting box 36 is connected to the side of the water tank 31. A servo motor 32 is connected to the lower end of the moving box 1. The output end is connected to the center of the lower end face of the dust collector box 33 through the inner wall of the water tank 31. One end of the air inlet pipe 35 is connected to the inside of the connecting box 36, and the other end of the air inlet pipe 35 is connected to the inside of the dust collector box 33. The lower end face of the dust collector box 33 is provided with a through hole. The lower end face of the water tank 31 is provided with a drain pipe. The side of the water tank 31 is provided with a water filling pipe. The sides of the drain pipe and the water filling pipe are sealed with sealing caps. The other end of the connecting pipe 23 is connected to the inside of the water tank 31.

[0029] Specifically, the output end of the servo motor 32 is coaxially connected to the center of the lower end face of the dust collection box 33, rather than a normal fixed connection. This design ensures that the dust collection box 33 is subjected to uniform force when rotating, avoiding uneven dust adsorption caused by eccentric rotation. At the same time, the servo motor 32 can adjust its speed. For example, when facing high concentrations of dust generated by wall grinding, the speed can be increased to enhance centrifugal force and improve dust separation efficiency.

[0030] The side of the positioning plate 34 is rotatably connected to the inner wall of the dust collector 33, and one end of the air inlet pipe 35 is connected to the positioning plate 34. On the one hand, the positioning plate 34 can fix the position of the air inlet pipe 35 in the dust collector 33, so as to prevent the air inlet pipe 35 from moving and causing the airflow channel to shift when the dust collector 33 rotates. On the other hand, the rotatable connection structure between the positioning plate 34 and the dust collector 33 can reduce the frictional wear of the air inlet pipe 35 when the dust collector 33 rotates, extend the service life of the components, and ensure that the airflow enters the dust collector 33 stably.

[0031] The through hole on the lower end face of the dust collector 33 is not a single round hole, but a number of small holes evenly distributed. This design allows the wastewater that adsorbs dust to flow back to the bottom of the water tank 31 quickly and evenly, preventing the wastewater from accumulating in the dust collector 33 and blocking the airflow channel. At the same time, the multiple small holes can prevent larger dust particles (such as wood chips) from falling directly into the water tank 31 and causing the drain pipe to be blocked, thus indirectly reducing the frequency of operation and maintenance.

[0032] In embodiment 2, the ventilation component 2 includes an electric fan 21, a dust collection hopper 22, and a connecting pipe 23. One end of the dust collection hopper 22 is connected to the interior of the connecting box 36, and one end of the connecting pipe 23 is connected to the air inlet of the electric fan 21. The side of the electric fan 21 is connected to the inner wall of the mobile box 1, and the side of the dust collection hopper 22 is connected to the inner wall of the mobile box 1.

[0033] Specifically, the side of the vacuum hopper 22 is connected to the inner wall of the mobile box 1, and its open end faces the outside of the mobile box 1. The open end of the vacuum hopper 22 adopts a trumpet-shaped design instead of a straight cylinder. The trumpet-shaped structure can expand the suction range of dust-laden air. For example, for local work points during decoration (such as window sill sanding or cabinet installation), the position of the mobile box 1 can be adjusted so that the open end of the vacuum hopper 22 is close to the work point, reducing dust diffusion. At the same time, the inner wall of the vacuum hopper 22 is made of smooth plastic material, which can prevent dust from accumulating in the vacuum hopper 22 and ensure smooth airflow into the connecting box 36.

[0034] Working principle: First, open the sealing cap of the water inlet pipe on the side of the water tank 31 and inject sufficient clean water into the water tank 31 (for subsequent dust adsorption). After filling, tighten the sealing cap to ensure the water tank 31 is airtight and prevent water leakage during subsequent operation. After the electric fan 21 is connected to the power supply, it starts to work. Its air inlet is connected to the inside of the water tank 31 through the connecting pipe 23. When running, a negative pressure (air pressure lower than the indoor atmospheric pressure) is formed in the channel formed by the connecting pipe 23, the connecting box 36, and the dust collection bucket 22. The dust-laden air in the room is first sucked in under the action of negative pressure. The dust collection hopper 22 (an open structure that expands the suction range and specifically absorbs dust from the renovation area) then carries the dust-laden air into the connecting box 36, where initial airflow is gathered. The dust removal component 3 is the core of the dust filtration system. Through a triple action of airflow guidance, rotational dust removal, and water adsorption, it separates and traps the dust in the air. Specifically, the dust-laden air in the connecting box 36 is guided into the dust removal box 33 through the air inlet pipe 35. One end of the air inlet pipe 35 is connected to the connecting box 36, and the other end is connected to the dust removal box 33. 3. The dust collector 33 maintains a relatively stable connection with the air inlet pipe 35 through the positioning plate 34 (the positioning plate 34 is rotatably connected to the inner wall of the dust collector 33 to prevent the airflow channel from being disrupted when the dust collector 33 rotates); the servo motor 32 on the lower end face of the moving box 1 is powered on and started, its output end penetrates the inner wall of the water tank 31 and is fixedly connected to the center of the lower end face of the dust collector 33, driving the dust collector 33 to rotate around the central axis inside the water tank 31. During the rotation, the dust-laden air inside the dust collector 33 will generate centrifugal force, causing the denser dust particles to move towards the dust collector 33. The inner wall is close; some of the clean water in the water tank 31 will enter the rotating dust collection box 33. The dust particles close to the inner wall of the dust collection box 33 will come into full contact with the clean water and be adsorbed under the action of centrifugal force (the surface tension of water can capture dust). The wastewater that adsorbs dust will flow back to the bottom of the water tank 31 through the through hole at the lower end of the dust collection box 33, realizing the separation of dust and air. The purified air can be directly discharged outdoors through the exhaust end of the electric fan 21, completely replacing the dust-containing air in the room and further enhancing the ventilation and dust reduction effect. At this point, the entire process is completed.
