Description

Technical Field

[0001] The present application relates to the technical field of dust removal and ventilation devices, and specifically to a dust removal and ventilation device for a cosmetics workshop. Background Art

[0002] As people's pursuit of beauty grows, the cosmetics industry has developed rapidly. During the processing and production of cosmetics, a large amount of dust and gases with various fragrances or odors are easily generated, which brings troubles to manufacturers. Dust removal and ventilation devices suitable for cosmetics workshops are particularly important.

[0003] A Chinese patent discloses a dust removal and ventilation device for a cosmetics workshop, with the authorization announcement number CN212692025U. The patent includes a fixed frame, a bellows is fixedly installed at the rear end of the fixed frame, a power mechanism is fixedly installed inside the bellows, a filter plate mechanism is clamped inside the fixed frame, the power mechanism penetrates the filter plate mechanism and is rotatably connected with the filter plate mechanism, and the fixed frame includes two symmetrically arranged clamping grooves, the two clamping grooves are fixedly installed on both sides of the front end of the bellows, a waste water tank is fixedly installed at the front end of the two clamping grooves, and an extrusion spring is fixedly installed inside the clamping grooves. The dust removal and ventilation device for a cosmetics workshop can clean the filter plate by setting a cleaning brush to rotate through a motor, and can also supply water to the cleaning brush through a limiting water ring, so that the filter plate can be cleaned, which solves the problem of poor exhaust caused by lack of cleaning of the filter plate in the prior art. However, the filter plate is cleaned by a cleaning brush, and the dust that falls off after cleaning is not collected. The dust is easy to fall and scatter, polluting the workshop environment again. In addition, the above device also supplies water in the limiting water ring into the cleaning brush to clean the filter plate, which makes the filter plate surface wet. The wet filter plate surface is more likely to absorb dust and particulate matter in the air, causing secondary contamination that is difficult to remove. Therefore, those skilled in the art provide a dust removal and ventilation device for a cosmetics workshop to solve the problems raised in the above background technology. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present application provides a dust removal and ventilation device for a cosmetics workshop, which solves the problems mentioned in the above background technology.

[0006] (II) Technical solution

[0007] To achieve the above purpose, the present application is implemented through the following technical solutions: A dust removal and ventilation device for a cosmetics workshop, comprising a shell, both ends of the shell are set as an opening structure, a filter screen plate with a movable structure is installed inside the shell, and the upper and lower ends of the filter screen plate are fixedly connected to a connecting plate that slides inside the shell, and three springs are equidistantly installed between one side of the two connecting plates and the inner wall of the shell;

[0008] A driving assembly for driving the connecting plate to move toward one side of the spring is arranged inside the shell and above the top connecting plate; the driving assembly comprises a rotating shaft rotatably connected inside the shell and above the connecting plate, two fixing sleeves symmetrically fixedly connected to the outside of the rotating shaft, four rotating rods equidistantly and symmetrically fixedly connected to the outside of the corresponding fixing sleeves, and a motor fixedly connected to the outside of the shell, the rotating rods can contact the connecting plate when rotating, and one end of the rotating shaft close to the motor passes through the inside of the shell and is fixedly connected to the output shaft of the motor;

[0009] A dust collecting groove is installed inside the bottom side of the shell and on a side of the filter screen plate away from the spring.

[0010] By adopting the above technical solution, the motor drives the fixed sleeve to rotate while driving the rotating rod to rotate. The rotating rotating rod contacts the connecting plate at the top of the filter screen, so that the filter screen can be driven to move to the side of the spring to compress the spring under the pushing action of the rotating rod. When the rotating rod continues to rotate and separates from the connecting plate, the filter screen can be better pushed to move to the side away from the spring under the action of the spring, realizing the vibration operation of the filter screen, which is similar to the slapping operation, and can better clean the dust accumulated on the filter screen to avoid affecting the filtering effect of the filter screen. At the same time, the dust dropped by the vibration falls into the dust collecting tank and can be collected in a centralized manner to facilitate subsequent processing, which has a better overall cleaning effect on the filter screen and is highly practical.

[0011] Preferably, an air inlet duct is fixedly connected to the inside of an opening of the shell near the dust collecting groove, and an exhaust fan is fixedly connected to the outside of another opening of the shell.

[0012] By adopting the above technical solution, the air inlet pipe is connected to the exhaust port of the cosmetics workshop, and can be used to draw air from the internal space of the workshop under the action of the exhaust fan to achieve ventilation of the workshop.

[0013] Preferably, an air duct valve is installed at one end of the air inlet duct close to the dust collecting tank.

[0014] By adopting the above technical scheme, the direction of the exhaust fan's internal motor can be controlled to switch the exhaust fan between forward and reverse rotation. The exhaust fan turns in the opposite direction to blow air to one side of the filter plate, and at the same time, the air duct valve is operated to cut off the air inlet duct. Under the vibration of the exhaust fan and the filter plate, the dust on the filter plate can be better cleaned, thereby ensuring the cleaning quality.

[0015] Preferably, the dust collecting tank is connected to the housing by bolts.

[0016] By adopting the above technical solution, the dust collecting trough installed by bolts has a stable connection and is easy to disassemble and assemble, thereby facilitating the cleaning of the dust collecting trough after disassembly.

[0017] Preferably, the dust collecting trough is configured as a trapezoidal structure.

[0018] By adopting the above technical solution, the dust collecting trough with a trapezoidal structure has an inclined structure, which is conducive to the dust sliding to the bottom of the dust collecting trough for collection.

[0019] Preferably, the motor and the exhaust fan are both electrically connected to an external control device.

[0020] By adopting the above technical solution, it is convenient to control the operating status of the motor and the exhaust fan, so as to facilitate the operation of the device.

[0021] (III) Beneficial effects

[0022] The present application provides a dust removal and ventilation device for a cosmetics workshop. The beneficial effects are as follows:

[0023] 1. The dust removal and ventilation device used in the cosmetics workshop sets the filter plate as an active structure under the action of a spring. The set driving component can realize the vibration operation of the filter plate, which is similar to a patting action, and can better clean the dust accumulated on the filter plate; at the same time, the dust dropped by the vibration falls into the dust collecting tank and can be collected centrally to facilitate subsequent processing. The overall cleaning effect of the filter plate is better and the practicability is strong.

[0024] 2. The cosmetics workshop uses a dust removal and ventilation device. By setting a duct valve on the air inlet duct to control the on-and-off of the air inlet duct, the reverse action of the exhaust fan can better clean the dust vibrating inside the filter plate, ensuring the cleaning quality.
