[0002] In the catering industry, a range hood is a necessary device, which is a kitchen appliance used to purify the kitchen environment. It is installed above the kitchen stove, and can quickly extract the waste generated by the stove combustion and the harmful oil fumes generated during the cooking process from the human body, discharge them outdoors, and at the same time condense and collect the oil fumes, reduce pollution, purify the air, and have the safety guarantee functions of preventing poison and explosion. During the actual use of the range hood, due to the position deviation between the range hood and the cooking area, the oil fumes are likely to flow out from both sides of the range hood, resulting in insufficient inhalation of the oil fumes and being likely to affect the surrounding environment. Content of the Utility Model

[0003] (1) Technical Problems to be Solved

[0004] In view of the deficiencies of the prior art, the utility model provides an environment-friendly range hood for catering, which solves the problems that during the use process, due to the position deviation between the range hood and the cooking area, the oil fumes are likely to flow out from both sides of the range hood, resulting in insufficient inhalation of the oil fumes and being likely to affect the surrounding environment.

[0005] (2) Technical Solutions

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: an environment-friendly range hood for catering, including a ventilation cylinder with a ventilation fan installed inside, a exhaust pipe for discharging fumes is connected to the top of the ventilation cylinder, a mounting plate is connected to the bottom of the ventilation cylinder, an aluminum foil composite pipe communicating with the ventilation cylinder is installed at the bottom of the mounting plate, a smoke collecting hood is connected to the bottom of the aluminum foil composite pipe, a smoke filtering component is installed inside the smoke collecting hood, a telescopic pipe is connected to the top of the smoke collecting hood, and a connection groove adapted to the telescopic pipe is provided at the bottom of the mounting plate.

[0007] Further, the smoke filtering component includes an iron bracket, a magnetic bracket installed inside the smoke collecting hood, and a water-absorbing filter paper between the two. The water-absorbing filter paper is provided with dense pores for the oil fumes to pass through. An oil cup is connected to the bottom of the magnetic bracket. A water storage cylinder is installed on the outer wall of the smoke collecting hood. A cotton rope is connected inside the water storage cylinder. One end of the cotton rope penetrates through the water storage cylinder and the smoke collecting hood and extends to the side of the iron bracket close to the water-absorbing filter paper. A through hole adapted to the cotton rope is provided at the bottom of the side wall of the water storage cylinder, and waterproof treatment is done at the through hole, and water will not flow out from the gap. The water in the water storage cylinder flows to the water-absorbing filter paper through the cotton rope by capillary action, making it wet. When the oil fumes pass through the water-absorbing filter paper, the oil fumes are easy to mix with the water, thereby improving the adsorption effect on the oil stains in the oil fumes, further reducing the impurities in the discharged oil fumes, and being beneficial to reducing the impact on the environment.

[0008] Furthermore, a plug rod is installed on the magnetic bracket, and a limiting ring adapted to the plug rod is installed on the side wall of the iron bracket.

[0009] Furthermore, a negative pressure fan is installed inside the smoke collecting hood and above the iron bracket. The negative pressure fan can improve the absorption effect of the smoke collecting hood on the oil fume.

[0010] Furthermore, there are two telescopic tubes located on both sides of the aluminum foil composite tube. The telescopic tube is composed of two sleeves that are sleeved with each other and will not separate. The two sleeves are in frictional contact. A screw rod threadedly connected to it penetrates through the bottom side of the outer wall of the top sleeve. The end of the screw rod abuts against the outer wall of the bottom sleeve, which can limit the length change of the telescopic tube. When the two sleeves are severely worn later, the length can still be controlled. A disc is provided at the top of the top sleeve, and the disc extends into the inner shell of the connection groove to prevent the telescopic tube from separating from the mounting plate.

[0011] Furthermore, both the iron bracket and the magnetic bracket are arc-shaped structures that bulge downward. The iron bracket, the water-absorbing filter paper, and the magnetic bracket are distributed from top to bottom in sequence. When the magnetic bracket is magnetically adsorbed below the iron bracket, its magnetic force can support the total weight of its own weight, the water-absorbing filter paper, and the oil cup full of oil stains.

[0012] (III) Beneficial Effects

[0013] The utility model provides an environment-friendly range hood for catering. It has the following beneficial effects:

[0014] 1. For this environment-friendly range hood for catering, by connecting an aluminum foil composite tube between the smoke collecting hood and the ventilation cylinder, the smoke collecting hood can move horizontally and vertically below the mounting plate. When cooking operations such as flipping the wok are required, it can be lifted to prevent the spatula from hitting the range hood. When the range hood is not directly above the cooking area, the smoke collecting hood can be moved to be directly above the cooking area to improve the absorption effect of the oil fume, and prevent the oil fume from spreading due to the deviation between the range hood and the cooking area, thus polluting the air.

[0015] 2. For this environment-friendly range hood for catering, the water in the water storage cylinder flows to the water-absorbing filter paper through the cotton rope by capillary action, making it wet. When the oil fume passes through the water-absorbing filter paper, the oil fume is easily mixed with water, thereby improving the adsorption effect on the oil stains in the oil fume, reducing the impurities in the discharged oil fume, and being beneficial to reducing the impact on the environment. At the same time, most of the oil stains adhere to the water-absorbing filter paper, and the magnetic bracket can be pulled down to be taken out, which greatly facilitates the cleaning operation of the range hood.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] An embodiment of the present utility model provides an environment-friendly range hood for catering, as Figures 1-6 shown, which includes a ventilation cylinder 2 with a ventilation fan installed inside. The top of the ventilation cylinder 2 is connected to an exhaust pipe 3 for exhausting smoke. The bottom of the ventilation cylinder 2 is connected to a mounting plate 1. The bottom of the mounting plate 1 is installed with an aluminum foil composite pipe 4 communicated with the ventilation cylinder 2. The aluminum foil composite pipe 4 is a mature existing product and is often used as the exhaust pipe of a range hood, having the performance of being bendable and telescopic. The bottom of the aluminum foil composite pipe 4 is connected to a smoke collecting hood 5. A smoke filtering component is installed inside the smoke collecting hood 5. The top of the smoke collecting hood 5 is connected to a telescopic pipe 6. The telescopic pipe 6 can fix the bottom end of the easily deformable aluminum foil composite pipe 4. A connection groove 7 adapted to the telescopic pipe 6 is provided at the bottom of the mounting plate 1. By connecting the aluminum foil composite pipe 4 between the smoke collecting hood 5 and the ventilation cylinder 2, the smoke collecting hood 5 can move horizontally and vertically below the mounting plate 1. When cooking operations such as flipping the wok are required, it can be moved upward to prevent the spatula from hitting the range hood. When the range hood is not directly above the cooking area, the smoke collecting hood 5 can be moved to be directly above the cooking area to improve the absorption effect of the smoke and prevent the smoke from spreading due to the deviation between the range hood and the cooking area, thus polluting the air.

[0025] Specifically, the smoke filtering component includes an iron bracket 8, a magnetic bracket 9 installed in the smoke collecting hood 5, and a water-absorbing filter paper 10 between the two. The water-absorbing filter paper 10 is provided with dense pores for the passage of oil fume. A grease cup 14 is connected to the bottom of the magnetic bracket 9. A water storage cylinder 11 is installed on the outer wall of the smoke collecting hood 5. A cotton rope 12 is connected inside the water storage cylinder 11. One end of the cotton rope 12 penetrates through the water storage cylinder 11 and the smoke collecting hood 5 and extends to the side of the iron bracket 8 close to the water-absorbing filter paper 10. A through hole adapted to the cotton rope 12 is provided at the bottom of the side wall of the water storage cylinder 11, and waterproof treatment is performed at the through hole, so that water will not flow out from the gap. The water in the water storage cylinder 11 flows to the water-absorbing filter paper 10 through the cotton rope 12 by capillary action, making it wet. When the oil fume passes through the water-absorbing filter paper 10, the oil fume is easy to mix with water, thereby improving the adsorption effect on the oil stains in the oil fume, reducing the impurities in the discharged oil fume, and being beneficial to reducing the impact on the environment.

[0026] Specifically, a plug rod 15 is installed on the magnetic bracket 9, and a limiting ring adapted to the plug rod 15 is installed on the side wall of the iron bracket 8.

[0027] Specifically, a negative pressure fan 13 is installed above the iron bracket 8 in the smoke collecting hood 5. The negative pressure fan 13 can improve the absorption effect of the smoke collecting hood 5 on the oil fume. A control switch electrically connected to the negative pressure fan 13 and the ventilation fan is installed on the outer wall of the smoke collecting hood 5.

[0028] Specifically, there are two telescopic pipes 6 and they are located on both sides of the aluminum foil composite pipe 4. The two telescopic pipes 6 are connected by an arc rod. The telescopic pipe 6 is composed of two sleeves that are sleeved with each other and will not separate. There is frictional contact between the two sleeves. A screw rod is threaded through the bottom side of the outer wall of the top sleeve. The end of the screw rod abuts against the outer wall of the bottom sleeve, which can limit the length change of the telescopic pipe 6, so that when the two sleeves are severely worn later, the length can still be controlled. A disc is provided at the top of the top sleeve, and the disc extends into the inner shell of the connection groove 7 to prevent the telescopic pipe 6 from separating from the mounting plate 1. The disc slides in the connection groove 7, thereby controlling the relative position of the telescopic pipe 6 and the mounting plate 1.

[0029] Specifically, both the iron bracket 8 and the magnetic bracket 9 are arc-shaped structures that bulge downward. The iron bracket 8, the water-absorbing filter paper 10, and the magnetic bracket 9 are distributed from top to bottom in sequence. When the magnetic bracket 9 is magnetically adsorbed below the iron bracket 8, its magnetic force can support the total weight of its own weight, the water-absorbing filter paper 10, and the grease cup 14 full of oil stains. The outer wall of the plug rod 15 is provided with an external thread. After the plug rod 15 penetrates through the limiting ring, a nut can be screwed on its outer wall to improve the fixing stability.

[0030] Working principle: When in use, an aluminum foil composite pipe 4 is connected between the smoke collecting hood 5 and the ventilation pipe 2, enabling the smoke collecting hood 5 to move horizontally and vertically below the mounting plate 1. When performing operations such as flipping the wok during cooking, it can move upward to prevent the spatula from hitting the range hood. When the range hood is not directly above the cooking area, the smoke collecting hood 5 can be moved to be directly above the cooking area to improve the absorption effect of oil fumes, preventing the oil fumes from spreading due to the deviation between the range hood and the cooking area and polluting the air. The water in the water storage cylinder 11 flows to the water absorption filter paper 10 through the cotton rope 12 by capillary action, making it moist. When the oil fumes pass through the water absorption filter paper 10, the oil fumes are easily mixed with the moisture, thereby improving the adsorption effect on the oil stains in the oil fumes. The accumulated oil stains gradually flow into the oil cup 14 for collection.
