Description

Technical Field

[0001] This application relates to the technical field of kitchen appliances, and in particular to a portable oil fume removal device. Background Technology

[0002] During cooking, a mixture of gases is produced due to the decomposition, volatilization, and oxidation of food at high temperatures. These fumes contain a large number of harmful substances, such as particulate matter, volatile organic compounds, aldehydes, and hydrocarbons, posing a serious threat to human health and the atmospheric environment. Long-term inhalation of cooking fumes can lead to respiratory diseases, cardiovascular diseases, and other health problems; at the same time, cooking fume emissions are also a significant source of air pollution.

[0003] To reduce the problem of cooking fume emissions, catering fume purification devices are widely used. They are mainly used in conjunction with cooking utensils used on family dining tables to separate the cooking fumes into grease and smoke, and purify the smoke.

[0004] A patent with publication number CN210717740U discloses a negative ion oil fume purification system, including an oil fume hood, a filter screen, a negative ion generator, an oil fume purification device, an exhaust fan, a flue, and a main controller. The filter screen, the oil fume purification device, and the exhaust fan are connected in series through the flue. The filter screen is located on the user side. The negative ion generator is located on the inner wall of the flue between the filter screen and the oil fume purification device. The oil fume hood is located outside the filter screen. The negative ion generator, the oil fume purifier, and the exhaust fan are all connected to the main controller.

[0005] However, the aforementioned negative ion fume purification system is quite large, making it inconvenient for daily transport and use. Utility Model Content

[0006] To effectively solve the above problems, this application provides a portable oil fume removal device.

[0007] This application provides a portable oil fume removal device, which adopts the following technical solution:

[0008] A portable oil fume removal device includes a base, a suction module and a processing module disposed on the base. The processing module includes a filter component, an oil fume purification component and an air outlet. The suction module includes a suction pump and an air inlet. An air duct connecting the suction module and the processing module is disposed on the base. The air duct is located below the processing module, and the air inlet and air outlet are located on both sides of the air duct.

[0009] By adopting the above technical solution, external oil fumes enter the equipment through the air inlet under the suction of the suction pump, and pass through the filter component and the oil fume purification component in sequence. When the high-temperature gaseous oil fumes flow through the filter component, the gaseous grease in the oil fumes liquefies upon contact with the cooler filter component, condenses into liquid grease, and adheres to the filter component. The filtered oil fumes then reach the oil fume purification component, which purifies the smoke particles in the oil fumes. The purified oil fumes are then discharged through the air outlet, improving the purification effect of oil fumes and reducing the pollution of some harmful substances in oil fumes to the atmosphere and human body. Furthermore, compared with existing technologies, this equipment has a simple structure, small size, and is easy for users to handle and use.

[0010] Optionally, the base is provided with a first housing and a second housing. The first housing covers the periphery of the suction pump, and the air inlet is located at the top of the first housing. The filter assembly and the oil fume purification assembly are installed in the second housing from bottom to top, and their air outlets are located at the top of the second housing.

[0022] The present application will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments are merely specific illustrations of the present application, and their purpose is to enable those skilled in the art to better understand the technical solutions of the present application, and should not be regarded as limitations on the present application.

[0023] In the description of this application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0024] This application discloses a portable oil fume removal device, such as... Figure 1 and Figure 2 As shown, the system includes a base 1, a suction module 2 and a processing module 3 mounted on the base 1. The suction module 2 includes a suction pump 21 and an air inlet 22. The processing module 3 includes a filter assembly 31, an oil fume purification assembly 32 and an air outlet 33 arranged in sequence. The base 1 is provided with an air duct 4 connecting the suction module 2 and the processing module 3. The air duct 4 is located below the processing module 3. The air inlet 22 and the air outlet 33 are located on both sides of the air duct 4.

[0025] External oil fumes enter the device through the air inlet 22 under the suction of the suction pump 21, and pass through the filter component 31 and the oil fume purification component 32 in sequence. When the high-temperature gaseous oil fumes flow through the filter component 31, the gaseous grease in the oil fumes liquefies upon contact with the relatively cool filter component 31, condenses into liquid grease, and adheres to the filter component 31. The filtered oil fumes then reach the oil fume purification component 32, where the smoke particles in the oil fumes are purified. The purified oil fumes are then discharged through the air outlet 33, improving the purification effect of the oil fumes and reducing the pollution of some harmful substances in the oil fumes to the atmosphere and human body. Moreover, compared with the existing technology, this device has a simple structure, small size, and is easy for users to handle and use.

[0026] Specifically, a first housing 5 with a bottom opening is fixedly mounted on the base 1. A suction pump 21 is fixedly mounted on the base 1, with the first housing 5 covering the outside of the suction pump 21. An air inlet 22 is located at the top of the first housing 5. A cavity 11 communicating with the air duct 4 is located inside the base 1 and below the suction pump 21. An air vent 12 is provided on the base 1 to connect the air inlet 22 and the cavity 11, so that external fumes, under the suction force of the suction pump 21, enter the cavity 11 through the air inlet 22 and the air vent 12, and then enter the processing module 3 through the air duct 4. In other embodiments, a first rim extending upwards is provided on the base 1 and around the suction pump 21, with the first housing 5 sleeved on the outside of the first rim or threadedly connected to the first rim.

[0027] A second housing 6 is provided on the base 1 and on one side of the first housing 5. The bottom of the second housing 6 is open. A second perimeter 13 extending upward is provided on the base 1. The second housing 6 is sleeved on the outside of the second perimeter 13 or the second housing 6 is threadedly connected to the second perimeter 13. The filter assembly 31 and the fume purification assembly 32 are installed in the second housing 6 from bottom to top. The air outlet 33 is located at the top of the second housing 6. The fumes entering through the air passage 4 pass through the filter assembly 31 and the fume purification assembly 32 in sequence. The purified fumes are discharged from the air outlet 33.

[0028] An oil collecting trough 14 is provided on the base 1 and below the processing module 3. The oil collecting trough 14 is connected to the air duct 4 so that the oil fumes passing through the air duct 4 enter the oil collecting trough 14, enter the interior of the second housing 6, and pass sequentially through the filter assembly 31 and the oil fume purification assembly 32. When the gaseous grease in the oil fume comes into contact with the relatively cool filter assembly 31, it liquefies, condenses into liquid grease, and adheres to the filter assembly 31. Then, under the action of gravity, it drips down into the oil collecting trough 14, facilitating the collection of liquid grease. The diameter of its second surrounding edge 13 is larger than the opening diameter of the oil collecting trough 14, so that the second housing 6 covers the oil collecting trough 14, preventing liquid grease from dripping to other parts of the base 1.

[0029] It should be noted that the top of the second housing 6 is open and covered with a cover 61, which covers the outside of the second housing 6, and the air outlets 33 are evenly distributed on the cover 61. The second housing 6 is detachably connected to the second perimeter 13 and the cover 61, which facilitates the cleaning or replacement of the inside of the second housing 6, the filter assembly 31 and the oil fume purification assembly 32, and helps to improve the purification effect of oil fumes.

[0030] The suction module 2 also includes a fan blade 23 connected to the suction pump 21. The fan blade 23 is located inside the cavity 11 and corresponds to the air duct 4. The suction pump 21 drives the fan blade 23 to rotate, which can assist the suction pump 21 in sucking external oil fumes into the cavity 11. Under the rotation of the fan blade 23, the oil fumes are blown through the air duct 4 to the oil receiving tank 14 and the interior of the second housing 6, so that the oil fumes pass through the filter assembly 31 and the oil fume purification assembly 32. The purified oil fumes are discharged from the air outlet 33. At the same time, it can also help the suction pump 21 dissipate heat and prevent the suction pump 21 from overheating and being damaged.

[0031] Combination Figure 3 The filter assembly 31 includes a fixing member 311 and at least two layers of filter screens 312. The at least two layers of filter screens 312 are installed on the fixing member 311, which can further improve the separation effect of gaseous grease and smoke particles and improve the purification effect of oil fume. It should be noted that there is a gap between the second perimeter 13 and the oil receiving groove 14. The fixing member 311 is placed in the gap to facilitate the installation and removal of the filter screens 312. At the same time, the filter screens 312 are located above the oil receiving groove 14 so that the liquid grease on the filter screens 312 can drip down into the oil receiving groove 14 and prevent the liquid grease from dripping to other positions of the base 1.

[0032] The inner wall of the second housing 6 is provided with a mounting groove 62, which extends to the bottom wall of the second housing 6. The mounting groove 62 is arranged around the circumference of the second housing 6, and its bottom wall abuts against the second perimeter 13. The inner wall of the mounting groove 62 is located above the fixing member 311, which can fix the filter assembly 31, thereby facilitating the installation and replacement of the filter assembly 31, helping to improve the filtration effect of the filter assembly 31, and thus improving the overall purification effect.

[0033] Furthermore, a spiral blade 63 is also provided inside the second housing 6. The spiral blade 63 is attached to the inner wall of the second housing 6 to form a spiral flue 64 inside the second housing 6. The oil fume purification component 32 includes at least two negative ion generators 321 disposed within the spiral flue 64. The negative ion generators 321 generate high voltage through a pulsed circuit, causing oxygen molecules in the air to ionize and generate negative ions. These negative ions have a strong adsorption capacity and can combine with positively charged particles such as smoke particles in the oil fume to form larger particles, which then settle downwards to the filter component 31, thereby achieving the effect of purifying the oil fume and reducing the pollution of the atmosphere by the discharged oil fume. Moreover, as the oil fume moves upward along the spiral flue 64, it ensures that the oil fume passes through the area where the negative ion generators 321 are located, thereby improving the purification effect of the oil fume.

[0034] The negative ion generator 321 includes an ion generating section, a high-voltage power supply, and a housing control section. The ion generating section is located inside the second housing 6, while the high-voltage power supply and housing control section are located outside the second housing 6. This effectively reduces the adhesion of impurities in oil fumes to the high-voltage power supply and housing control section, thus minimizing their impact on the lifespan of the negative ion generator 321. A protective shell is provided outside the second housing 6, enclosing the high-voltage power supply and housing control section and providing protection for them.

[0035] Because the spiral blade 63 is fitted against the inner wall of the second housing 6, it can be initially fixed. Furthermore, the gap between the spiral blade 63 and the filter assembly 31 is small. When the spiral blade 63 moves downwards under gravity, the filter assembly 31 can support the spiral blade 63 without affecting the negative ion generator 321. In other embodiments, the top of the spiral blade 63 is fixedly attached to the cover 61.

[0036] To improve the purification effect of cooking fumes, negative ion generators 321 are installed at the front, middle and end of the spiral flue 64, which can purify the undecomposed smoke particles at the front, thereby further improving the purification effect of cooking fumes.

[0037] An oil collection box 15, which is detachably installed on the base 1 and below the oil collection tank 14, communicates with the oil collection tank 14. The liquid grease adsorbed on the filter assembly 31 drips downwards into the oil collection tank 14 under the action of gravity, and then drips down along the oil collection tank 14 into the oil collection box 15. The user can remove the oil collection box 15 to process the collected grease. The oil collection tank 14 is funnel-shaped to facilitate the downward dripping of grease from the oil collection tank 14 into the oil collection box 15.

[0038] Example 2:

[0039] The difference between this embodiment and embodiment 1 is that: a first housing 5 and a second housing 6 are provided on the base 1. The first housing 5 covers the periphery of the suction pump 21, and the air outlet 33 is located at the top of the first housing 5; the filter assembly 31 and the oil fume purification assembly 32 are installed in the second housing 6 from top to bottom, and its air inlet 22 is located at the top of the second housing 6.

[0040] The inner wall of the second housing 6 is provided with a mounting groove 62, which extends upward to the top wall of the second housing 6. The fixing member 311 of the filter assembly 31 is installed in the mounting groove 62, and the cover 61 is located above the filter assembly 31.

[0041] External fumes enter the second housing 6 through the air inlet 22 under the suction of the suction pump 21, and pass through the filter assembly 31 and the fume purification assembly 32 in sequence. When the high-temperature gaseous fumes flow through the filter assembly 31, the gaseous grease in the fumes liquefies upon contact with the cooler filter assembly 31, condenses into liquid grease, and adheres to the filter assembly 31. The liquid grease drips downwards onto the spiral blades 63 under gravity, and then drips down along the spiral blades 63 into the oil collection tank 14. The filtered fumes flow downwards along the spiral flue 64. The negative ions generated by the negative ion generator 321 can combine with positively charged particles such as smoke particles in the fumes to form larger particles, which then sink downwards into the oil collection tank 14. The purified fumes enter the cavity 11 through the air duct 4 and are discharged through the air outlet 12. While purifying the fumes, this process also prevents the fumes from adhering to the suction pump 21 and the fan blades 23.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
