[0045] Portable range hoods are used in a wide range of scenarios. Since they are easy to carry around, users can easily use this product to filter oil fumes and avoid polluting the environment, whether they are camping outdoors or barbecuing outdoors. However, for different scenarios, the concentration of oil fumes that need to be filtered by portable range hoods is different. If only a fixed filter device is used, it is impossible to balance the flow rate of oil fume processing and the efficiency of oil fume purification, resulting in the inability to quickly process light oil fumes, and in heavy oil fume scenarios, it is easy for oil fumes to be discharged without being completely purified. Moreover, fixing the filter device in the portable range hood will make it complicated for users to replace the filter device, and it is easy to dirty their hands and cannot be handled cleanly.

[0046] To solve this problem, the present invention discloses a portable range hood. Figure 4 , Figure 5 and Figure 8 As shown, the portable range hood includes a body 100, a fan assembly 200 disposed inside the body, a first filter device 300 disposed on one side of the body, and a second filter device 400 disposed on the other side of the body. The body 100 is opened at both ends to form a hollow cylindrical structure, and a fume passage 120 is formed in the body 100, wherein one end of the body 100 forms an air inlet 121 of the portable range hood, and the other end forms an air outlet 122 of the portable range hood, and a first connecting device 110 is provided at the air outlet 122, and the first connecting device 110 cooperates with a second connecting device 420 disposed on the second filter device 400 to realize a detachable connection between the second filter device 400 and the body 100. Optionally, the first connecting device 110 is an iron sheet, and the second connecting device 420 is a magnet, and the detachable connection between the second filter device 400 and the body 100 is realized by magnetic force. By providing a second filter device 400 that is convenient for installation and disassembly relative to the main body 100, the user can adjust the air volume and oil fume filtering capacity of the portable range hood by disassembling and assembling the second filter device 400. The disassembly and assembly process is quick and easy to operate, will not cause pollution to the user's hands, and is easy to market.

[0047] Specifically, the body 100 includes a front cover 130 disposed at the air inlet 121, a grid 140 disposed at the air outlet 122, and a support portion 150 disposed below. The body 100 ensures the stable placement of the portable range hood through the support portion 150, and accommodates the fan assembly 200 in the oil fume passage 120 through the front cover 130 and the grid 140. When the fan assembly 200 starts to work, the fan assembly 200 guides the airflow to be sucked in from the front cover 130 at the air inlet 121, passes through the oil fume passage 120, and then is discharged from the grid 140.

[0048] Alternatively, if Figure 3 As shown, a counterweight block 151 is provided in the support portion 150, and the counterweight block 151 ensures that the portable range hood is stably placed in any scenario. Figure 2 and Figure 3 As shown, the support portion 150 is provided with a battery compartment 152 and a power socket 153, so that the user can use the portable range hood in scenarios with or without an external power supply. Figure 1 and Figure 2 As shown, a handle 160 is pivotally connected to the body 100 , and the handle 160 can rotate around the body 100 to provide a structure convenient for users to carry when the portable range hood needs to be moved, making the portable range hood more convenient and easy to use.

[0049] Furthermore, if Figure 1 and Figure 3 As shown, the first filter device 300 is clamped at the center of the front cover 130, and the front cover 130 is clamped and connected with the body 100, so that the user can remove the front cover 130 from the body 100 to clean or replace the first filter device 300. Further, a wrench 131 is provided on the front cover 130 to facilitate the user to install or remove the front cover 130. Further, after the first filter device 300 is clamped at the center of the front cover 130, it is arranged perpendicular to the path of the airflow to ensure that the oil smoke sucked into the oil smoke channel 120 passes through the first filter device 300. Optionally, the first filter device 300 is an activated carbon filter, a stainless steel filter or a filter formed of other materials to quickly absorb particles and droplets in the oil smoke without affecting the airflow rate.

[0050] In one embodiment, Figure 4As shown, the portable range hood further includes a third filter device 500, which is clamped between the first filter device 300 and the fan assembly 200 and is arranged perpendicular to the path of the airflow, so as to further purify the oil smoke passing through the first filter device 300 and improve the purification effect of the oil smoke. Since the third filter device 500 is clamped between the first filter device 300 and the fan assembly 200, the third filter device 500 can be conveniently and quickly taken out for cleaning or replacement after the front cover 130 is removed, which is simple and clean to operate without contaminating the user's hands. Further, for light oil smoke scenes, the third filter device 500 can be removed, and only the first filter device 300 is retained in front of the fan assembly 200 to avoid affecting the airflow flow and avoiding dispersing the airflow through the oil smoke channel 120, so that the oil smoke passes through the fan assembly 200 and passes through the second filter device 400 more concentratedly, achieving more efficient filtering and purification of the oil smoke; and for heavy oil smoke scenes, the third filter device 500 can be installed to increase the purification effect of the oil smoke, reduce the burden of the first filter device 300 and the second filter device 400, and extend the service life of the first filter device 300 and the second filter device 400. Optionally, the third filter device 500 is an activated carbon filter, a stainless steel filter or a filter formed of other materials, and the third filter device 500 can use a filter structure different from the first filter device 300 to adsorb pollutants of different sizes and shapes in the oil smoke.

[0051] Furthermore, if Figure 6 and Fig. 9 As shown, the second filter device 400 is arranged at the air outlet 122 and corresponds to the grid 140, and the second filter device 400 is perpendicular to the air flow path of the oil smoke through the oil smoke channel 120 to ensure that all the oil smoke output from the air outlet 122 passes through the second filter device 400 before being discharged from the portable range hood.

[0052] In one embodiment, Figure 4As shown, the second filter device 400 includes a main body 410 and a filter 430, wherein the main body 410 is an annular structure, and the filter 430 is clamped at the center of the main body 410 and arranged perpendicular to the axial direction of the main body 410, so as to ensure that the filter 430 is arranged perpendicular to the airflow path of the oil smoke when the second filter device 400 is connected to the main body 100. The second connecting device 420 is arranged on the side of the main body 410 facing the main body 100, and the second filter device 400 and the main body 100 are disassembled and assembled through the cooperation of the second connecting device 420 and the first connecting device 110 on the main body 100; the handle 411 is arranged on the side of the main body 410 away from the main body 100, so as to facilitate the user to install the second filter device 400 on the main body 100 or remove it from the main body 100. Optionally, the second connecting device 420 is a magnet, and the first connecting device 110 is an iron sheet. The second filtering device 400 is detachably connected to the main body 100 through magnetic force, so that the user can install or remove the second filtering device 400 according to different scenarios to adjust the filtering and purification effect of the portable range hood on oil fumes.

[0053] Specifically, the filter 430 is an activated carbon filter, a stainless steel filter or a filter formed of other materials. The filter 430 can use a filter structure different from the first filter device 300 and the third filter device 500 to adsorb pollutants of different sizes and shapes in the oil fume. Further, by adjusting the material, thickness, area, density and / or porosity of the filter 430, the filter 430 has a stronger filtering and purifying ability for oil fume than the first filter device 300 and the third filter device 500, so as to ensure that the purification ability of the portable range hood for oil fume can be improved after the second filter device 400 is installed, so that the user can install or remove the second filter device 400 as needed to adjust the filtering and purification effect of the portable range hood for oil fume. Optionally, the filter 430 is a plasma filter.

[0054] In another embodiment, if Figure 5 and Figure 6As shown, the second filter device 400 includes a main body 410, a filter cover 450 and a filter 430, wherein the filter cover 450 is connected to the main body 410 by clamping, so as to clamp and fix the filter 430 inside the second filter device 400. Further, the filter cover 450 is arranged on a side of the main body 410 away from the main body 100, and a handle 411 is provided on the filter cover 450, so that after the filter cover 450 is clamped with the main body 410, the user can quickly install the second filter device 400 on the main body 100 or remove it from the main body 100 through the handle 411.

[0055] Specifically, Figure 5 As shown, the second connecting device 420 is provided on one side of the main body 410 facing the main body 100, and the second connecting device 420 cooperates with the first connecting device 110 on the main body 100 to realize the disassembly and assembly of the second filter device 400 and the main body 100. Optionally, the second connecting device 420 is a magnet, and the first connecting device 110 is an iron sheet, and the detachable connection between the second filter device 400 and the main body 100 is realized by magnetic force, so that the user can install or remove the second filter device 400 according to different scenarios to adjust the filtering and purification effect of the portable range hood on oil smoke.

[0056] Furthermore, if Figure 6 As shown, the main body 410 is annular in structure and is arranged corresponding to the grid 140 at the air outlet 122 of the main body 100 to ensure that the oil smoke passing through the oil smoke channel 120 and output from the air outlet 122 all enters the second filter device 400 through the main body 410. Furthermore, the filter cover 450 is hollowed out to form a filter grid 451 corresponding to the position of the filter 430 to perform the last step of adsorption on the oil smoke passing through the filter 430, thereby improving the filtering and purification effect of the second filter device 400 on the oil smoke. Specifically, the grid density of the filter grid 451 is less than the grid density of the grid 140 at the air outlet 122 to ensure that the purified oil smoke can be smoothly discharged from the second filter device 400.

[0057] Specifically, the filter 430 is an activated carbon filter, a stainless steel filter or a filter formed of other materials. The filter 430 can use a filter structure different from the first filter device 300 and the third filter device 500 to adsorb pollutants of different sizes and shapes in the oil fume. Further, by adjusting the material, thickness, area, density and / or porosity of the filter 430, the filter 430 has a stronger filtering and purifying ability for oil fume than the first filter device 300 and the third filter device 500, so as to ensure that the purification ability of the portable range hood for oil fume can be improved after the second filter device 400 is installed, so that the user can install or remove the second filter device 400 as needed to adjust the filtering and purification effect of the portable range hood for oil fume. Optionally, the filter 430 is a plasma filter.

[0058] In yet another embodiment, Figure 7 , Figure 8 and Fig. 9 As shown, the second filter device 400 includes a main body 410, a filter 430 and a filter mounting sleeve 440. The main body 410 and the filter mounting sleeve 440 are both annular structures, and the outer diameter of the filter mounting sleeve 440 is adapted to the inner diameter of the main body 410, so as to facilitate the clamping of the filter mounting sleeve 440 inside the main body 410. Further, the filter mounting sleeve 440 accommodates the filter 430, and when the filter mounting sleeve 440 is clamped in the main body 410, it is ensured that the filter 430 is arranged perpendicular to the air flow path of the oil smoke in the oil smoke channel 120, so as to ensure that after the second filter device 400 is connected to the main body 100, the oil smoke output from the air outlet 122 all enters the second filter device 400 and passes through the filter 430, so as to achieve further filtering and purification of the oil smoke.

[0059] Specifically, Fig.10 and Fig.11 As shown, both ends of the filter installation sleeve 440 extend radially toward the center of the filter installation sleeve 440, and a circle of clamping protrusions 441 are formed at both ends of the filter installation sleeve 440. The filter installation sleeve 440 accommodates the filter 430 in the center through the clamping protrusions 441 and ensures the specific setting direction of the filter 430. Optionally, the filter installation sleeve 440 is a flexible silicone sleeve, so that the filter 430 can be easily clamped between the two circles of the clamping protrusions 441, and the filter 430 can be taken out of the filter installation sleeve 440, which is convenient for users to clean and replace the filter 430.

[0060] Specifically, the filter 430 is an activated carbon filter, a stainless steel filter or a filter formed of other materials. The filter 430 can use a filter structure different from the first filter device 300 and the third filter device 500 to adsorb pollutants of different sizes and shapes in the oil fume. Further, by adjusting the material, thickness, area, density and / or porosity of the filter 430, the filter 430 has a stronger filtering and purifying ability for oil fume than the first filter device 300 and the third filter device 500, so as to ensure that the purification ability of the portable range hood for oil fume can be improved after the second filter device 400 is installed, so that the user can install or remove the second filter device 400 as needed to adjust the filtering and purification effect of the portable range hood for oil fume. Optionally, the filter 430 is a plasma filter.

[0061] Furthermore, if Fig.10 and Fig.11 As shown, a clamping piece 442 is formed on the outer wall of the filter installation sleeve 440 extending radially outward, so that the outer diameter of the filter installation sleeve 440 is increased at the clamping piece 442 to facilitate the clamping and fixing of the filter installation sleeve 440 and the main body 410. Furthermore, the filter installation sleeve 440 is extended axially to form a handle 443 to facilitate the user to take the filter installation sleeve 440 out of the main body 410, making the disassembly and assembly of the second filter device 400 more convenient and quick.

[0062] Specifically, Fig.11 and Fig.12 As shown, a slot 412 is provided on the inner wall of the main body 410 corresponding to the clamping piece 442 of the filter mounting sleeve 440, so that the inner diameter of the main body 410 at the slot 412 matches the outer diameter of the filter mounting sleeve 440 at the clamping piece 442, and the clamping piece 442 is accommodated by the slot 412 to achieve the clamping of the filter mounting sleeve 440 at the center position of the main body 410.

[0063] Furthermore, if Figure 8As shown, the second connecting device 420 is provided on the side of the main body 410 facing the main body 100, and the second connecting device 420 cooperates with the first connecting device 110 on the main body 100 to realize the disassembly and assembly of the second filter device 400 and the main body 100; the handle 411 is provided on the side of the main body 410 away from the main body 100, so as to facilitate the user to install the second filter device 400 on the main body 100 or remove it from the main body 100. Optionally, the second connecting device 420 is a magnet, and the first connecting device 110 is an iron sheet, and the detachable connection between the second filter device 400 and the main body 100 is realized by the action of magnetic force, so as to facilitate the user to install or remove the second filter device 400 according to different scenarios, so as to adjust the filtering and purification effect of the portable range hood on oil smoke.

[0064] Furthermore, if Figure 7 and Fig.11 As shown, the main body 410 fixes the filter installation sleeve 440 at the center of the main body 410 through the card cover 413 and the baffle 416, wherein the card cover 413 is detachably connected to the main body 410 through the buckle 415, and the baffle 416 is a circle of protrusions formed by extending radially toward the center of the main body 410 on one side of the main body 410. The card cover 413 cooperates with the baffle 416 to fix the filter 430 at the center of the second filter device 400, so as to ensure that the filter 430 is arranged perpendicular to the air flow path of the oil smoke in the oil smoke channel 120, so as to ensure that after the second filter device 400 is connected to the main body 100, all the oil smoke output from the air outlet 122 enters the second filter device 400 and passes through the filter 430, so as to further filter and purify the oil smoke.

[0065] Optionally, the installation mode of the filter installation sleeve 440 relative to the main body 410 can be adjusted by changing the relative position relationship between the card cover 413 and the baffle 416 on the main body 410. When the baffle 416 is a circle of protrusions formed on the side of the main body 410 away from the main body 100, the card cover 413 is correspondingly arranged on the side of the main body 410 facing the main body 100. At this time, the card cover 413 is provided with a yielding portion 414 at the position corresponding to the second connecting device 420, so that the second connecting device 420 can extend and cooperate with the first connecting device 110 to realize the detachable connection between the second filter device 400 and the main body 100. At the same time, the filter installation sleeve 440 under this setting needs to be disassembled from the side of the main body 410 facing the main body 100, that is, the second filter device 400 needs to be removed from the main body 100 before the filter installation sleeve 440 and the filter 430 are disassembled, so that the setting of the filter 430 in the second filter device 400 is more stable. In another configuration, the baffle 416 is a circle of protrusions formed on the side of the main body facing the main body 100, and the card cover 413 is correspondingly arranged on the side of the main body away from the main body 100. At this time, the filter installation sleeve 440 is disassembled from the side of the main body 410 away from the main body 100, and the card cover 413 is removed from the main body 410 to remove the filter installation sleeve 440 from the main body 410, so as to clean or replace the filter 430, which is convenient for users to operate.

[0066] The present invention increases the filtering structure on the portable range hood by providing a second filtering device detachably connected to the main body. At the same time, the user can disassemble and assemble the second filtering device according to the needs of the cooking process or kitchen conditions, so as to timely adjust the filtering capacity of the portable range hood. The filtering capacity can be adjusted without shutting down the portable range hood, and the operation is convenient and quick. At the same time, the disassembly and assembly is aimed at the entire second filtering device, and the user does not need to touch the filter that absorbs the oil fume particles. Therefore, the user can quickly and cleanly replace the filter, avoiding the user's hands from being stained with oil, and the use is more convenient and comfortable.

[0067] In summary, the present invention discloses a portable range hood, comprising a body, a fan assembly, a first filter device and a detachable second filter device.
