Description

Technical Field

[0001] The utility model relates to the technical field of oil fume purifiers, in particular to a silent oil fume purifier. Background Art

[0002] A fume purifier is a device for treating oil fume waste gas, which mainly includes a fume hood, ventilation ducts, exhaust fans, purification equipment and mufflers. The purification equipment generally adopts a "static + mechanical" dual purification structure, that is, the negatively charged ions generated by the static electrode can effectively capture small-size oil fume particles, and then through mechanical multi-stage filtration, the oil fume particles can be effectively removed to achieve a purification effect.

[0003] Most of the existing silent oil fume purifiers directly pass the oil fume through the filter and then discharge it outward. After a long period of accumulation, the grease will slowly flow down along the filter into the collection tank for collection. This collection method has a low oil collection and filtration efficiency. After long-term use, the filtering effect of the range hood will be further reduced, and it is not easy to clean the grease, which still causes many inconveniences when using it.

[0004] Therefore, we propose a silent oil fume purifier to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0023] See also Figure 1 - Figure 3 A silent oil fume purifier comprises a shell 1 and a connecting pipe 2 fixedly installed on the upper end of the shell 1, a smoking pipe 3 is installed at one end of the connecting pipe 2, a trumpet-shaped pipe 21 is fixedly installed at one end of the connecting pipe 2, a suction fan 22 is fixedly installed inside the connecting pipe 2, a chamber 11 is opened inside the shell 1, one end of the connecting pipe 2 extends into the lower end of the chamber 11, a foam board 12 is slidably connected in the chamber 11, an oil storage component 4 is installed on the side wall of the shell 1, an opening 15 is opened on the side wall of the shell 1, a slider 151 is slidably connected in the opening 15, and a slide groove 152 is opened at the upper end of the opening 15.

[0024] When the oil fume purifier is used, the suction fan 22 is started, and the oil fume is sucked from the smoking pipe 3 by the suction fan 22. The airflow enters the connecting pipe 2 along the trumpet-shaped pipe 31 and finally flows into the interior of the chamber 11. A certain amount of water is initially injected into the chamber 11. The sucked oil fume gas is directly passed into the water at the lower end of the chamber 11 along the connecting pipe 2. After the oil fume is passed into the water, the grease particles in the oil fume remain on the water surface. When the grease layer gradually increases, the grease layer will lift the foam board 12 upward, and the foam board 12 will lift upward. When it rises to the opening 15, the foam board 12 lifts the slider 151 upwards. As the gas continuously enters the interior of the chamber 11, the air pressure in the chamber 11 increases, and the slider 151 is lifted upwards until it slides in the slide groove 152. At this time, part of the grease will automatically enter the interior of the oil storage component 4. The device can directly pass the oil fume gas into the water, use water to separate the grease particles in the oil fume gas and keep them on the water surface, and when the grease accumulates to a certain amount, it is automatically sucked into the interior of the oil storage component 4 for storage, which is convenient for cleaning. Example

[0025] See also Figure 2 - Figure 6 The oil storage assembly 4 includes an oil storage shell 41 fixedly mounted on the side wall of the shell 1, an oil storage chamber 42 is provided in the oil storage shell 41, an oil inlet 44 is provided on the side of the oil storage shell 41, the oil inlet 44 is connected with the opening 15, and an air outlet 43 is provided at the upper end of the oil storage shell 41. With the cooperation between the oil storage shell 41, the oil storage chamber 42, the oil inlet 44, the opening 15 and the air outlet 43, when the oil storage chamber 42 is connected with the chamber 11, the gas will flow out along the air outlet 43.

[0026] A fixed plate 13 is fixedly installed on the inner wall of the chamber 11, and a piston slider 14 is slidably connected to the inside of the chamber 11. The fixed plate 13 and the foam plate 12 are respectively provided with an air outlet 2 131 and an air outlet 3 121. With the cooperation between the chamber 11, the fixed plate 13, the piston slider 14, the foam plate 12, the air outlet 2 131 and the air outlet 3 121, the piston slider 14 will be lifted upward when the gas in the chamber 11 increases.

[0027] An opening 141 is provided on the piston slider 14, and a movable component 16 is installed in the opening 141. The movable component 16 includes a fixed tube 161 fixedly installed in the opening 141, and four air outlets 162 are equidistantly provided on the side wall of the fixed tube 161. A telescopic ring 163 is fixedly installed on the upper end of the piston slider 14, and a spring 164 is fixedly installed between the upper and lower ends of the inner wall of the telescopic ring 163. The telescopic ring 163 and the spring 164 are sleeved on the outer side of the fixed tube 161. With the cooperation between the piston slider 14, the opening 141, the fixed tube 161, the four air outlets 162, the telescopic ring 163 and the spring 164, the telescopic ring 163 blocks the four air outlets 162 in a natural state, and the piston slider 14 can be lifted upward.

[0028] An opening 17 is provided at the upper end of the shell 1, and an exhaust assembly 18 is installed in the opening 17. The exhaust assembly 18 includes an exhaust pipe 181 fixedly installed in the opening 17, and a movable cover 182 is slidably connected to the upper end of the exhaust pipe 181. A spring 183 is fixedly installed between the side wall of the movable cover 182 and the upper wall of the shell 1. With the cooperation between the shell 1, the opening 17, the exhaust pipe 181, the movable cover 182 and the spring 182, when the airflow is large enough, the movable cover 182 can be lifted upward to exhaust air outward from the exhaust pipe 181.

[0029] A smoking port 31 is provided at one end of the smoking pipe 3, an oil storage ring 32 is fixedly installed on the side wall of the smoking pipe 3, and a filter 33 is fixedly installed in the middle of the oil storage ring 32. With the cooperation between the smoking pipe 3, the smoking port 31, the oil storage ring 32 and the filter 33, the oil smoke will be filtered through the filter 33 before entering the chamber 11, and the oil storage ring 32 can intercept the oil stains remaining on the side wall of the smoking pipe 3 and retain them therein.

[0030] When the oil fume purifier is used, the suction fan 22 is started, and the suction fan 22 sucks the oil fume into the smoking pipe 3 along the smoking port 31. The oil fume completes the first filtration through the filter 33 and enters the interior of the smoking pipe 3. A part of the oil fume will remain on the inner wall of the oil suction pipe 3. After a long period of accumulation, the oil droplets will flow down along the side wall of the oil suction pipe 3 into the oil storage ring 32. The suction fan 22 sucks the oil fume into the connecting pipe 2 and passes it into the chamber 11. At this time, the gas in the chamber 11 is getting more and more, the piston slider 14 is lifted upward, and the grease layer in the chamber 11 gradually becomes thicker. The telescopic ring 163 contacts the opening 17. When the piston slider 14 is continuously lifted, the telescopic ring 163 is squeezed and compressed. At this time, the fixed pipe 161 slides into the exhaust pipe 181 , the fixed tube 161 pushes the movable cover 182 upwards, and after the movable cover 182 is pushed open, the gas is discharged outwardly along the air outlet four 162, so that the air pressure in the chamber 11 is reduced. However, since there is only one air outlet four 162 to exhaust outwards, when the grease layer becomes thicker, the foam board 12 lifts the slider 151. At this time, the chamber 11 and the oil storage chamber 42 are connected, and part of the gas flows outwardly along the air outlet one 43. At this time, an external suction force is generated at the opening 15, and the grease at the opening 15 is sucked into the inside of the oil storage chamber 42 for storage. When the device is in use, the gas sucked in by the suction fan 22 increases the air pressure in the chamber 11, and the grease is automatically sucked out by the increased air pressure. The grease can be easier to clean by introducing the fumes into water.
