Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly water-cooled fume hood technology, specifically an environmentally friendly water-cooled fume hood. Background Technology

[0002] Water-cooled fume hoods are a new type of environmentally friendly product, typically made of stainless steel. Features include fully automatic control, fire resistance, and a water spray system that separates the hood from the exhaust duct, preventing the spread of heat from the air intake. They are also aesthetically pleasing, durable, and easy to clean, as oil stains do not easily accumulate. Single and double water-cooled fume hoods are available. Water-cooled fume hoods can achieve an oil purification rate of over 90%, with oil and odor isolation capabilities reaching 93%, and a 55% chance of effectively solving air pollution and wall staining problems.

[0003] A search revealed that Chinese patent application number 202121236337.4 discloses an environmentally friendly water-cooled fume hood, comprising an outer shell, a gas collection hood, a liquid storage tank, an air inlet, a water inlet pipe, and a mixing tank. The liquid storage tank is connected to the outer shell and communicates with the interior of the outer shell. A control valve is provided on the drain pipe a on the bottom surface of the liquid storage tank. The air inlet connects the lower end face of the outer shell and the side end face of the liquid storage tank. An air inlet chamber communicating with the outer shell is provided inside the air inlet. An air inlet is provided on the lower end face of the air inlet. Multiple sets of exhaust devices are provided on the upper end face of the outer shell. The gas collection hood is connected to the upper end face of the outer shell and covers the outside of the multiple sets of exhaust devices. An exhaust pipe is provided on the gas collection hood. The mixing tank is connected to the inner wall of the outer shell through multiple sets of connecting rods. A drain pipe b communicating with the interior of the mixing tank is provided on the lower end face of the mixing tank. Multiple nozzles are evenly distributed on the drain pipe b. A flow control valve is provided on the water inlet pipe. The water inlet pipe connects to the outer shell and extends into the outer shell in a sealed manner to communicate with the mixing tank. This invention can purify and adsorb oil fumes, preventing them from polluting the environment.

[0004] Although the aforementioned patent can purify and absorb oil fumes, preventing them from polluting the environment, in actual use, the patent lacks a height adjustment structure, making it difficult to adjust its height after installation. This means it cannot be adjusted according to the amount of oil fumes produced by the dish or the user's height, which may reduce the smoke extraction effect and thus reduce the practicality of the patent.

[0005] Therefore, it is necessary to modify the environmentally friendly water-cooled fume hood in the above patent to effectively prevent the problem that the height of the environmentally friendly water-cooled fume hood cannot be adjusted after installation. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 3As shown, this utility model provides an environmentally friendly water-cooled fume hood, including a mounting frame 1. A drive box 2 is fixedly connected to the front of the mounting frame 1. A drive motor 3 is fixedly connected to the inner wall of the drive box 2. A rotating shaft 4 is fixedly connected to the output end of the drive motor 3. Bearing seats 5 are symmetrically sleeved on the surface of the rotating shaft 4, and the bearing seats 5 are fixedly connected to the drive box 2. A first helical gear 6 is symmetrically sleeved on the surface of the rotating shaft 4. A second helical gear 7 meshes with the bottom of the first helical gear 6. A threaded rod 8 is fixedly connected to the inner wall of the second helical gear 7, and the surface of the threaded rod 8 is rotatably connected to the drive box 2 through a bearing component. A bearing block 9 is rotatably connected to the bottom of the threaded rod 8, and the back of the bearing block 9 is fixedly connected to the mounting frame 1. A threaded block 10 is threadedly connected to the surface of the threaded rod 8, and the threaded block 10 is slidably connected to the mounting frame 1. A connector 11 is fixedly connected to the front of the threaded block 10, and the main body 12 of the water-cooled fume hood is fixedly connected to the front of the connector 11.

[0022] refer to Figure 3 The bottom of the drive box 2 is symmetrically fixedly connected with a limiting strip 13. The inner wall of the limiting strip 13 is provided with a sliding groove 14. A slider 15 is slidably connected inside the sliding groove 14, and the slider 15 is fixedly connected to the threaded block 10.

[0023] As a technical optimization of this utility model, by setting the limiting bar 13, the sliding groove 14 and the slider 15, the movement trajectory of the threaded block 10 can be limited, and the stability of the threaded block 10 during movement can be improved.

[0024] refer to Figure 1 , Figure 2 and Figure 3 A limiting groove 16 is provided on the front of the limiting strip 13, and a limiting block 17 is symmetrically fixedly connected to the back of the water-cooled fume hood body 12, with the limiting block 17 slidingly connected to the limiting groove 16.

[0025] As a technical optimization of this utility model, the setting of the limiting groove 16 and the limiting block 17 can help support the water-carrying fume hood body 12 and improve the stability of the water-carrying fume hood body 12 when it is raised and lowered.

[0026] refer to Figure 1 and Figure 2 The bottom of the support block 9 is fixedly connected to a tripod 18, and the other side of the tripod 18 is fixedly connected to the mounting bracket 1.

[0027] As a technical optimization of this utility model, the setting of the tripod 18 can improve the support strength of the bearing block 9 and strengthen the connection between the bearing block 9 and the mounting frame 1.

[0028] refer to Figure 1 and Figure 2 The top of the main body 12 of the water-cooled fume hood is connected to a retractable exhaust pipe 19.

[0029] As a technical optimization of this utility model, the retractable exhaust pipe 19 can be used to extend and retract the exhaust pipe according to the lifting and lowering of the water-cooled fume hood body 12, thereby preventing the leakage of oil fumes.

[0030] refer to Figure 1 and Figure 2 The front of the main body 12 of the water-cooled fume hood is provided with a lifting switch 20, and the lifting switch 20 is electrically connected to the drive motor 3.

[0031] As a technical optimization of this utility model, the lifting switch 20 makes it easy for the user to start the drive motor 3, thereby facilitating the lifting and lowering of the water-cooled fume hood body 12.

[0032] The working principle and usage process of this utility model are as follows: First, the device is installed in the designated position through the pre-drilled holes on the mounting bracket 1. Then, the device is connected to an external power supply device. When the user needs to adjust the height of the environmentally friendly water-cooled fume hood, they only need to press the lifting switch 20 to start the drive motor 3 to rotate forward or reverse. This drives the rotating shaft 4 and the first helical gear 6 to rotate forward or reverse. Since the first helical gear 6 meshes with the second helical gear 7, it drives the second helical gear 7 and the threaded rod 8 to rotate forward or reverse, thereby achieving the lifting and lowering movement of the threaded block 10. Then, through the connecting piece 11, the water-cooled fume hood body 12 can be lifted and lowered. At this time, the slider 15 on the threaded block 10 slides in the sliding groove 14, and the limiting block 17 slides in the limiting groove 16, thus assisting in supporting the water-cooled fume hood body 12. This allows the water-cooled fume hood body 12 to rise and fall along with the threaded block 10, thereby enabling the height of the water-cooled fume hood body 12 to be adjusted according to the degree of oil fume from the dish and the user's height.
