Description

Technical Field

[0001] The utility model relates to the technical field of oil fume purification, in particular to an oil fume purification device. Background Art

[0002] At present, in the related technology, the purifier generally uses the activated carbon layer on the filter net to filter the air. When the purifier purifies the air, water vapor will be adsorbed on the activated carbon filter cotton, causing the activated carbon filter cotton to be contaminated, resulting in a decrease in the filtering effect of the purification component, thereby affecting the working efficiency of the purifier. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] To this end, a first aspect of the utility model provides an oil fume purification device.

[0005] In view of this, the first aspect of the utility model provides an oil fume purification device, comprising: a shell, a condensation net, a purification component, a fan component and a liquid receiving portion. The shell has a cavity, an air inlet and a first air outlet, the air inlet is connected to the first air outlet through the cavity; the condensation net is arranged at the air inlet; the purification component is arranged in the cavity, and the fan component is arranged in the cavity, the fan component can drive the gas outside the oil fume purification device to enter the cavity through the condensation net, and after the driven gas passes through the purification component, it is discharged from the cavity through the first air outlet, in the projection of the height direction of the shell, the liquid receiving portion is located between the purification component and the condensation net, and the liquid flowing down the condensation net can flow into the liquid receiving portion.

[0006] A fume purification device provided in the present application includes a shell. The shell surrounds a cavity. The cavity connects the air inlet and the first air outlet so that the gas can flow between the air inlet and the first air outlet. A fan assembly is arranged in the cavity, and the purification assembly is arranged in the cavity so that the gas in the cavity flows from the purification assembly to the fan assembly, reducing the gas backflow to the side of the purification assembly close to the air inlet, avoiding the purified gas from being contaminated, thereby further improving the filtering efficiency of the purification assembly. When the fume purification device is in working state, the fan assembly drives the gas outside the fume purification device into the cavity, and then the gas is filtered by the purification assembly and flows out of the cavity through the first air outlet. In this process, the external gas includes water vapor, and a condensation net is provided at the air inlet of the shell. The wind component drives the gas outside the oil fume purification device to enter the cavity after passing through the condensation net at the air inlet, and then is discharged from the cavity through the first exhaust port after being filtered by the purification component; on the one hand, by providing the condensation net at the air inlet, the user can observe the cleanliness of the condensation net at any time, which is convenient for the user to clean and replace the condensation net. On the other hand, by providing the condensation net at the air inlet, through the cooperation of the condensation net and the purification component, the oil fume purification device can purify the air while the condensation net of the oil fume purification device condenses the gas passing through the condensation net, liquefies the water vapor in the gas and precipitates it from the gas, thereby reducing the amount of water vapor carried in the gas passing through the purification component, reducing the pollution of the purification component by water vapor, and thus improving the working efficiency of the oil fume purification device.

[0007] When the oil fume purification device is working, the gas can flow along the thickness direction of the oil fume purification device, enter the cavity through the condensation net arranged at the air inlet, and then flow along the height direction of the shell, thereby ensuring the filtering effect of the purification component on the gas while reducing the lateral size of the purification component, and reducing the size of the space occupied by the purification component on the horizontal plane in the oil fume purification device, thereby reducing the area occupied by the oil fume purification device when placed, allowing the oil fume purification device to be flexibly placed, and also making the appearance of the oil fume purification device thinner and lighter, improving the aesthetics while making it more convenient to move and store.

[0008] At the same time, the liquid receiving part can recycle the liquid condensed by the condensation net, improve the working effect of the oil fume purification device, avoid the damage of the condensed water to the oil fume purification device, facilitate the user to deal with the condensed waste water, simplify the treatment work, and improve the working efficiency of the oil fume purification device.

[0009] The liquid receiving part can guide the condensed waste water and make it flow out of the oil fume purification device in a directional manner, which is convenient for the discharge of the condensed water. At the same time, the liquid receiving part can also be set to store the condensed waste water, so that the waste water can be stored in the liquid receiving part after condensation, which is convenient for the user to uniformly treat the condensed waste water after use, reduce the difficulty of treatment, and improve the working effect of the oil fume purification device.

[0010] Furthermore, the liquid receiving part and the purification component can be provided as an integrated structure, thereby facilitating the production and installation of the liquid receiving part and reducing production costs. The liquid receiving part and the purification component can also be provided as a split connection, thereby enabling the liquid receiving part to be disassembled and the waste water in the liquid receiving part to be poured out when there is too much condensed waste water stored in the liquid receiving part, thereby improving the treatment efficiency of the condensed waste water.

[0011] Furthermore, the oil fume purification device of the present application can also be used to purify high-temperature oil fume and water vapor generated in various cooking scenarios, condense the water vapor through a condensation net, and then filter the oil fume through a purification component.

[0012] Furthermore, the condensation net may be arranged on a side of the air inlet away from the cavity, so that the condensation net and the purification component are effectively separated in space, thereby preventing condensed water generated on the condensation net from contaminating the purification component.

[0013] Furthermore, the condensation net can be used as a filter, so that larger particles in the gas passing through the condensation net are blocked outside the condensation net, thereby achieving a filtering effect.

[0014] Furthermore, the condensation net includes a filter net and an aluminum net. The aluminum net is arranged on the filter net or the aluminum net and the filter net are attached to each other. The filter net blocks larger particles in the gas passing through the condensation net outside the condensation net to achieve a filtering effect. The aluminum net condenses water vapor in the gas passing through the condensation net.

[0015] Furthermore, the purification component can be arranged close to the air inlet, thereby facilitating the user to replace the purification component.

[0016] In addition, the oil fume purification device in the above technical solution provided by the utility model may also have the following additional technical features:

[0017] In some technical solutions of the present utility model, optionally, the condensation net, the purification component and the fan component are arranged along the height direction.

[0018] In this embodiment, the condensation net, the purification component and the fan component are arranged along the height direction, that is, the condensation net is on the top wall of the purification component. When the oil fume purification device is working, the fan component drives the gas, and the condensation net of the oil fume purification device condenses the gas passing through the condensation net. The condensation net precipitates water vapor in the gas from the gas, thereby reducing the amount of water vapor carried in the gas passing through the purification component, reducing the pollution of the water vapor to the purification component, and thus improving the working efficiency of the oil fume purification device.

[0019] The condensation net, purification component and fan component are arranged in the height direction, and the airflow flows in the thickness direction. After passing through the condensation net, the airflow passes through the purification component in the height direction, so that the interior of the cavity no longer needs to reserve space for gas flow on the side of the purification component away from the condensation net, thereby reducing the size of the oil fume purification device in the thickness direction, which is conducive to the lightweight design of the oil fume purification device.

[0020] Furthermore, in the height direction, the height of the condensation net is higher than the height of the purification component, but the condensation net and the purification component are staggered in the thickness direction.

[0021] In the height direction, the height of the purification component is higher than that of the fan component, and the purification component and the fan component are opposite or staggered in the thickness direction.

[0022] In some technical solutions of the present utility model, optionally, the condensation net is inclined downward relative to the height direction.

[0023] In this embodiment, the condensation net is arranged to be tilted downward relative to the height direction. Under the influence of gravity, the condensation water adsorbed by the condensation net is effectively drained and collected along the surface of the condensation net to the edge of the condensation net and then falls down. The condensation water attached to the condensation net is reduced, which reduces the rate at which the condensation water affects the passage of the gas through the condensation net, prevents the condensation water on the condensation net from directly dripping onto the purification component, and reduces the contamination of the purification component by the condensation water.

[0024] Furthermore, the inclination angle of the condensation net relative to the height direction is within an angle range such that the condensed water on the condensation net can flow along the condensation net to the edge of the condensation net due to its own gravity.

[0025] In some technical solutions of the present invention, optionally, the condensation net is located at the top of the liquid receiving portion, and in the height direction, the middle part of the condensation net is higher than the edge of the condensation net.

[0026] In this embodiment, when the condensation net is arranged on the top of the liquid receiving part, the middle of the condensation net is higher than the edge of the condensation net in the height direction. That is, the condensation net is arranged to be higher in the middle, and at least the edges on both sides are lower than the middle of the condensation net. The condensed water generated by the condensation net flows from various positions of the condensation net to the edge of the condensation net due to its own gravity, preventing the condensed water on the condensation net from directly dripping on the purification component, thereby reducing the contamination of the purification component by the condensed water.

[0027] Furthermore, when the condensation net is arranged parallel or nearly parallel to the top of the purification component, the condensation net can be a conical surface with a high middle and low edges, so that the condensed water on the condensation net can be more easily drained and collected along the surface of the condensation net due to its own gravity, while preventing the condensed water on the condensation net from dripping directly onto the purification component.

[0028] In some technical solutions of the present utility model, the purification assembly also includes a first bracket and a purification component. The first bracket is connected to the shell and is located in the cavity. The first bracket includes an installation cavity. The purification component is arranged in the installation cavity, and the purification component is a porous adsorption filter.

[0029] In this embodiment, the purification component includes a first bracket and a purification component. The first bracket is connected to the shell and is located in the cavity. The purification component is arranged on the first bracket and arranged along the first direction. By arranging the purification component of the purification component in the installation cavity of the first bracket, the first bracket plays a role in protecting and supporting the purification component in the installation cavity, and at the same time, the gas flow rate passing through the purification component can be large and stable, thereby improving the filtering efficiency of the purification component. The purification component is set as a porous adsorption filter to filter the gas passing through the purification component.

[0030] Furthermore, the porous adsorption filter can be activated carbon or an electrostatic module.

[0031] Furthermore, the activated carbon can be honeycomb activated carbon, which ensures a good filtering effect while being convenient for users to clean it after use, thereby ensuring the normal operation of the oil fume purification device.

[0032] Furthermore, the first bracket and the shell are detachably connected, so that the user can take out the first bracket after the oil fume purification device stops working.

[0033] Furthermore, the installation cavity of the first bracket and the purification component are detachable structures, so that when the oil fume purification device stops working, it is convenient for the user to take out the purification component.

[0034] In some technical solutions of the utility model, the liquid receiving portion further includes a liquid storage cavity, which is located on one side of the installation cavity, or is arranged around the installation cavity, and the liquid storage cavity can store liquid flowing down the condensation net.

[0035] In this embodiment, a liquid storage chamber is provided on one side of the first bracket or around the installation cavity. The liquid storage chamber collects and stores condensed water generated by condensed water vapor on the condensation net, preventing the condensed water from flowing into the installation cavity and then contaminating the purification components in the installation cavity.

[0036] Furthermore, the first bracket and the liquid storage chamber are detachable structures, so that the user can pour out the condensed water in the liquid storage chamber after use.

[0037] Furthermore, the liquid storage chamber and the installation chamber are an integrated structure, so that the production cost of the liquid storage chamber and the installation chamber is low, and it is convenient for the user to clean the liquid storage chamber and the installation chamber at the same time.

[0038] In some technical solutions of the utility model, the liquid receiving portion further includes a guide channel, one end of which can receive the liquid flowing down from the condensation net, and the other end of which extends to the liquid storage chamber.

[0039] In this embodiment, the liquid receiving portion further includes a guide channel, and one end of the guide channel can receive the liquid flowing down from the condensation net, and the other end extends into the liquid storage cavity, so that the condensed water on the condensation net flows along the condensation net to the liquid receiving portion between the condensation net and the purification component due to its own gravity. Since one end of the guide channel can receive the liquid flowing down from the condensation net, the condensed water is guided by the guide channel connected to the liquid receiving portion to the liquid storage cavity of the first bracket, and the guide channel plays a role in guiding the condensed water, thereby reducing the condensed water from flowing to the purification component in the installation cavity.

[0040] In some technical solutions of the present utility model, the liquid receiving portion is arranged on the first bracket.

[0041] In this embodiment, the liquid receiving portion is disposed on the first bracket, and the first bracket provides fixed support for the liquid receiving portion to facilitate installation of the liquid receiving portion.

[0042] Specifically, the liquid receiving part and the first bracket can be set to be connected in an integrated manner to improve assembly efficiency, or the liquid receiving part and the first bracket can be set to be connected in a split manner to improve the flexibility of installation of the liquid receiving part, facilitate removal of the liquid receiving part, process condensed water, and also facilitate cleaning of the liquid receiving part.

[0043] In some technical solutions of the present utility model, the guide channel extends obliquely downward from the liquid receiving portion toward the liquid storage cavity.

[0044] In this embodiment, the guide channel extends downwardly from the liquid receiving portion toward the liquid storage chamber. The inclined guide channel can accelerate the discharge of condensed waste liquid, facilitate the recovery and treatment of condensed waste liquid, and avoid the accumulation of condensed waste liquid in the oil fume purification device.

[0045] In some technical solutions of the utility model, the oil fume purification device further includes: a second bracket, an air intake component and a pressure plate. The second bracket is connected to the housing; the air intake component is connected to the second bracket, and the air intake component is provided with an air inlet; the condensation net covers the air inlet and is located on a side of the air intake component close to the cavity; the pressure plate is connected to the second bracket and is pressed on a side of the condensation net away from the air intake component.

[0046] In this embodiment, the oil fume purification device includes a second bracket. The second bracket is connected to the air intake component and the pressure plate, respectively, and is used to support and fix the air intake component and the pressure plate. At the same time, when a large amount of air flows through the condensation net through the air inlet, the gas force generated will act on the condensation net. By setting the condensation net to cover the air inlet of the air intake component, the pressure plate of the second bracket is pressed on the side of the condensation net away from the air intake component. The cooperation between the air intake component and the pressure plate plays a role in fixing the condensation net, thereby reducing the deviation of the condensation net when it is subjected to gas force.

[0047] In some technical solutions of the present invention, the second bracket is connected to the first bracket, and the second bracket and the first bracket are an integrated structure or a split structure.

[0048] In this embodiment, the first bracket and the second bracket are provided as an integrated structure, thereby reducing the production cost.

[0049] By arranging the first bracket and the second bracket as a split structure, it is convenient for a user to replace the first bracket and the second bracket separately, thereby reducing maintenance costs.

[0050] In some technical solutions of the present utility model, the air intake component protrudes from the side wall of the second bracket, and the air intake port faces the bottom of the shell.

[0051] In this embodiment, the air intake component is arranged to protrude from the side wall of the second bracket, and the air intake port faces the bottom of the shell, so that the air intake component can easily collect gas moving upward and in the direction of the air intake port.

[0052] Furthermore, when the oil fume purification device is used to purify the oil fume generated by cooking utensils in various cooking environments, it is convenient to collect the oil fume generated by cooking utensils in various cooking environments.

[0053] In some technical solutions of the utility model, the fan assembly includes: a volute, an impeller and a driving component. The volute is connected to the housing, and is provided with a second air outlet, which is opposite to the first air outlet; the impeller is arranged in the volute; the power output end of the driving component is connected to the impeller, and can drive the impeller to rotate.

[0054] In this embodiment, the power output of the driving component of the fan assembly can drive the impeller of the fan assembly to rotate, and the air in the volute of the fan assembly is discharged from the volute through the second air outlet. At the same time, by setting the second air outlet of the volute opposite to the first air outlet, it is convenient for the air in the cavity to flow out of the oil fume purification device through the volute, and at the same time, the gas backflow to the side of the purification assembly close to the air inlet is reduced, so as to avoid the purified gas being contaminated and needing to pass through the purification assembly again, thereby further improving the filtering efficiency of the purification assembly.

[0055] Furthermore, the impeller can be a forward centrifugal impeller, which, in conjunction with the volute, can generate a greater wind pressure, thereby improving the filtering effect of the purification component and thus improving the working efficiency of the oil fume purification device.

[0056] Furthermore, the driving component is a motor commonly seen in daily life.

[0057] In some technical solutions of the utility model, the condensation net is a metal net or a plastic net, and the purification component is an adsorption filter material.

[0058] In this embodiment, by setting the condensation net to be a metal material, the heat dissipation of the condensation net can be fast, and by setting the condensation net to be a plastic net, the weight of the condensation net can be reduced, which is convenient for injection molding production of the condensation net. The purification component can be set as an adsorption filter material, thereby ensuring the purification effect while improving the production efficiency of the purification component.

[0059] Furthermore, the material of the condensation net can also be other materials with good heat dissipation and high heat resistance, such as aluminum, stainless steel and plastic.

[0060] Furthermore, the adsorption filter material can be activated carbon, electrostatic adsorption filter material, PP substrate, HAPA net and HAPA net of composite activated carbon.

The cavity 110 connects the air inlet 120 and the first air outlet 130, so that the gas can flow between the air inlet 120 and the first air outlet 130. A purification component 300 and a fan component 400 are arranged in the cavity 110. When the oil fume purification device 10 is in working state, the fan component 400 drives the gas outside the oil fume purification device 10 into the cavity 110, and then the gas is filtered by the purification component 300 and flows out of the cavity 110 through the first air outlet 130. During this process, the external gas includes water vapor, and a condensation net 200 is set at the air inlet 120 of the shell 100. The wind component drives the gas outside the oil fume purification device 10 to enter the cavity 110 after passing through the condensation net 200 at the air inlet 120, and then is discharged from the cavity 110 through the first exhaust port after being filtered by the purification component 300. On the one hand, by setting the condensation net 200 at the air inlet 120, the user can observe the cleanliness of the condensation net 200 at any time, which is convenient for the user to clean and replace the condensation net 200. On the other hand, by setting a condensation net 200 at the air inlet 120 and through the cooperation between the condensation net 200 and the purification component 300, the oil fume purification device 10 can purify the air while the condensation net 200 of the oil fume purification device 10 condenses the gas passing through the condensation net 200, liquefies the water vapor in the gas and precipitates it from the gas, thereby reducing the amount of water vapor carried in the gas passing through the purification component 300, reducing the pollution of the purification component 300 by water vapor, and thus improving the working efficiency of the oil fume purification device 10.

[0080] The liquid receiving portion 314 can guide the condensed waste water and make it flow out of the oil fume purification device 10 in a directional manner, which is convenient for the discharge of the condensed water. At the same time, the liquid receiving portion 314 can also be set to store the condensed waste water, so that the waste water can be stored in the liquid receiving portion 314 after condensation, which is convenient for the user to uniformly treat the condensed waste water after use, reduce the difficulty of treatment, and improve the working effect of the oil fume purification device 10.

[0081] Furthermore, the liquid receiving portion 314 and the oil fume purification device 10 may be provided as an integrated structure, thereby facilitating the production and installation of the liquid receiving portion 314 and reducing production costs. The liquid receiving portion 314 and the oil fume purification device 10 may also be provided as a split connection, thereby enabling the liquid receiving portion 314 to be disassembled and the wastewater in the liquid receiving portion 314 to be poured out when too much condensed wastewater is stored in the liquid receiving portion 314, thereby improving the treatment efficiency of the condensed wastewater.

[0082] Furthermore, the oil fume purification device 10 of the present application can also be used to purify high-temperature oil fume and water vapor generated in various cooking scenarios, condense the water vapor through the condensation net 200, and then filter the oil fume through the purification component 300.

[0083] Furthermore, the condensation net 200 may be disposed at a side of the air inlet 120 away from the cavity 110 , so that the condensation net 200 and the purification component 300 are effectively separated in space, thereby preventing the condensed water generated on the condensation net 200 from contaminating the purification component 300 .

[0084] Furthermore, the condensation net 200 can be used as a filter to block larger particles in the gas passing through the condensation net 200 from outside the condensation net 200, thereby achieving a filtering effect.

The main body portion 150 includes: a first housing 151, and the first housing 151 is detachably connected to the main body portion 150 or connected to a rotating shaft. By disassembling the first housing 151 or rotating it relative to the main body portion 150, it is convenient for the user to disassemble and observe the fan assembly 400 in the main body portion 150.

[0089] The condensation net 200 , the purification assembly 300 and the fan assembly 400 are arranged along the height direction A.

[0090] In this embodiment, if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, by arranging the condensation net 200, the purification component 300 and the fan component 400 along the height direction, that is, the condensation net 200 is on the top wall of the purification component 300, when the oil fume purification device 10 is working, the fan component 400 drives the gas, and the condensation net 200 of the oil fume purification device 10 condenses the gas passing through the condensation net 200, and precipitates water vapor in the gas from the gas, thereby reducing the amount of water vapor carried in the gas passing through the purification component 300, reducing the pollution of the purification component 300 by water vapor, and thus improving the working efficiency of the oil fume purification device 10.

[0091] The condensation net 200, the purification component 300 and the fan component 400 are arranged in the height direction, and the airflow flows in the thickness direction. After passing through the condensation net 200, the airflow passes through the purification component 300 in the height direction, so that the interior of the cavity no longer needs to reserve space for gas flow on the side of the purification component 300 away from the condensation net 200, thereby reducing the size of the oil fume purification device 10 in the thickness direction, which is conducive to the lightweight design of the oil fume purification device 10.

[0092] Further, in the height direction, the height of the condensation net 200 is higher than the height of the purification assembly 300, but the condensation net 200 and the purification assembly 300 are staggered in the thickness direction.

[0093] In the height direction, the height of the purification component 300 is higher than the height of the fan component 400, and the purification component 300 and the fan component 400 are opposite or staggered in the thickness direction.

[0094] This embodiment provides an oil fume purification device 10. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0095] The condensation net 200 is inclined downward relative to the height direction A.

[0096] In this embodiment, if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, by setting the condensation net 200 to be tilted downward relative to the height direction A, the condensed water adsorbed by the condensation net 200 will be effectively drained and collected along the surface of the condensation net 200 to the edge of the condensation net 200 under the influence of its own gravity, and then fall down, the condensed water attached to the condensation net 200 is reduced, which plays a role in reducing the rate at which the condensed water affects the passage of the gas through the condensation net 200, and prevents the condensed water on the condensation net 200 from directly dripping onto the purification component 300, thereby reducing the contamination of the purification component 300 by the condensed water.

[0097] Furthermore, the inclination angle of the condensation net 200 relative to the height direction A is within an angle range such that the condensed water on the condensation net 200 can flow along the condensation net 200 to the edge of the condensation net 200 due to its own gravity.

[0098] This embodiment provides an oil fume purification device 10. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0099] The condensation net 200 is located at the top of the liquid receiving portion 314 , and in the height direction, the middle of the condensation net 200 is higher than the edge of the condensation net 200 .

[0100] In this embodiment, if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the condensation net 200 is arranged at the top of the liquid receiving portion 314, the middle of the condensation net 200 is higher than the edge of the condensation net 200 in the height direction. That is, the condensation net 200 is arranged to be high in the middle, and at least the edges on both sides are lower than the middle of the condensation net 200. The condensed water adsorbed by the condensation net 200 flows from various positions of the condensation net 200 to the edge of the condensation net 200 due to its own gravity, preventing the condensed water on the condensation net 200 from directly dripping on the purification component 300, thereby reducing the contamination of the purification component 300 by the condensed water.

[0101] Furthermore, when the condensation net 200 is arranged parallel or nearly parallel to the top of the purification component 300, the condensation net 200 can be a conical surface with a high middle and low edges, so that the condensed water on the condensation net 200 can be better drained and collected along the surface of the condensation net 200 due to its own gravity, while preventing the condensed water on the condensation net 200 from dripping directly onto the purification component 300.

[0102] This embodiment provides an oil fume purification device 10. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0103] The purification component 300 also includes a first bracket 310 and a purification component 320. The first bracket 310 is connected to the shell 100 and is located in the cavity 110. The first bracket 310 includes an installation cavity 311; the purification component 320 is arranged in the installation cavity 311, and the purification component 320 is a porous adsorption filter.

[0104] In this embodiment, if Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the purification component 300 includes a first bracket 310 and a purification component 320. The first bracket 310 is connected to the housing 100 and is located in the cavity 110. The purification component 320 is arranged on the first bracket 310 and arranged in the height direction. By setting the purification component 320 of the purification component 300 in the installation cavity 311 of the first bracket 310, the first bracket 310 plays a role in protecting and supporting the purification component 320 in the installation cavity 311, and at the same time, the gas flow rate passing through the purification component 300 can be large and stable, which improves the filtration efficiency of the purification component 300. It can also make the gas in the cavity 110 flow from the purification component 300 to the fan component 400, reduce the gas backflow to the side of the purification component 300 close to the air inlet 120, avoid the purified gas from being contaminated, and further improve the filtration efficiency of the purification component 300. The purification component 320 is set as a hole adsorption filter to filter the gas passing through the purification component 300.

[0105] Furthermore, the porous adsorption filter can be activated carbon or an electrostatic module.

[0106] Specifically, the activated carbon can be honeycomb activated carbon, which ensures a good filtering effect while being convenient for users to clean it after use, thereby ensuring the normal operation of the oil fume purification device 10.

[0110] The liquid receiving portion 314 further includes a liquid storage cavity 312 , which is located on one side of the mounting cavity 311 , or is arranged around the mounting cavity 311 , and the liquid storage cavity 312 can store liquid flowing down from the condensation network 200 .

[0111] In this embodiment, if Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the liquid receiving portion 314 also includes a liquid storage chamber 312. By arranging the liquid storage chamber 312 on one side of the first bracket 310 or around the installation chamber 311, the liquid storage chamber 312 collects and stores the condensed water adsorbed on the condensation net 200 to prevent the condensed water from flowing into the installation chamber 311, thereby preventing the condensed water from contaminating the purification component 300 in the installation chamber 311.

[0112] Furthermore, the first bracket 310 and the liquid storage chamber 312 are detachable structures, so that the user can pour out the condensed water in the liquid storage chamber 312 after use.

[0113] Furthermore, the liquid storage chamber 312 and the installation chamber 311 are an integrated structure, so that the production cost of the liquid storage chamber 312 and the installation chamber 311 is low, and it is convenient for the user to clean the liquid storage chamber 312 and the installation chamber 311 together.

[0114] This embodiment provides an oil fume purification device 10. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0115] The liquid receiving portion 314 further includes a guide channel 313 , one end of which is capable of receiving the liquid flowing down from the condensation network 200 , and the other end of which extends to the liquid storage chamber 312 .

[0116] In this embodiment, if Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the liquid receiving portion 314 also includes a guide channel 313, and one end of the guide channel 313 can receive the liquid flowing down from the condensation net 200, and the other end extends into the liquid storage chamber 312. The condensed water on the condensation net 200 flows along the condensation net 200 to the liquid receiving portion 314 between the condensation net 200 and the purification component 320 due to its own gravity. Since one end of the guide channel 313 can receive the liquid flowing down from the condensation net 200, the condensed water is guided by the guide channel 313 connected to the liquid receiving portion 314 to the liquid storage chamber 312 of the first bracket 310, which plays a role in guiding the condensed water, thereby reducing the condensed water from flowing to the purification component 300 in the installation chamber 311.

[0117] This embodiment provides an oil fume purification device 10. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0118] The liquid receiving portion 314 is disposed on the first bracket 310 .

[0120] Specifically, the liquid receiving part 314 and the first bracket 310 can be set to be connected in an integrated manner, thereby improving the assembly efficiency, or the liquid receiving part 314 and the first bracket 310 can be set to be connected in a split manner, which can improve the flexibility of installing the liquid receiving part 314, facilitate the removal of the liquid receiving part 314, handle the condensed water, and also facilitate the cleaning of the liquid receiving part 314.

[0121] This embodiment provides an oil fume purification device 10. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0122] The guiding channel 313 extends obliquely downward from the liquid receiving portion 314 toward the liquid storage chamber 312 .

The second bracket 500 is respectively connected to the air intake component 600 and the pressing plate 700, and is used to support and fix the air intake component 600 and the pressing plate 700. At the same time, when a large amount of air flows through the condensation net 200 through the air inlet 120, the gas force generated will act on the condensation net 200. By setting the condensation net 200 to cover the air inlet 120 of the air intake component 600, the pressing plate 700 of the second bracket 500 is pressed on the side of the condensation net 200 away from the air intake component 600. The cooperation between the air intake component 600 and the pressing plate 700 plays a role in fixing the condensation net 200, thereby reducing the displacement of the condensation net 200 when it is subjected to gas force.

[0127] Furthermore, the second bracket 500 and the shell 100 are detachably connected or connected by a rotating shaft, so that the purification component 300 in the cavity 110 can be easily taken out after the oil fume purification device 10 is working.

[0134] This embodiment provides an oil fume purification device 10. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0135] The air inlet component 600 protrudes from the side wall of the second bracket 500 , and the air inlet 120 faces the bottom of the housing 100 .

[0136] In this embodiment, if Figure 6 , Figure 7 and Figure 8 As shown, by arranging the air intake component 600 to protrude from the side wall of the second bracket 500 and the air inlet 120 to face the bottom of the housing 100 , the air intake component 600 can easily collect gas moving upward and in the direction of the air inlet 120 .

At the same time, by setting the second air outlet 411 of the volute 410 opposite to the first air outlet 130, it is convenient for the air in the cavity 110 to flow out of the oil fume purification device 10 through the volute 410, and at the same time, the gas backflow to the side of the purification assembly 300 close to the air inlet 120 is reduced, so as to avoid the purified gas from being polluted. The polluted gas needs to pass through the purification assembly 300 again, thereby further improving the filtering efficiency of the purification assembly 300.
