[0035] To make the technical problems solved by the present utility model, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the present utility model will be further described below with reference to the drawings and through specific implementation manners. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the present utility model are shown in the drawings rather than all of them.

[0036] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0037] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0038] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on the top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under" and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is lower than that of the second feature. In the description of this embodiment, if not otherwise specified, "a plurality of" specifically refers to two or more.

[0039] In the description of this embodiment, the terms such as "above", "below", "right", etc., indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] In the purification device in the prior art, the spray head is fixedly installed on the purification box body, the distance between the spray head and the inlet pipe is fixed and unchanged, and the cleaning process of the spray head has many steps, which is not convenient for operation and will also lead to a reduction in the sealing performance of the purification device and a low cleaning efficiency.

[0041] For this reason, this embodiment provides a purification device with high flexibility and good absorption effect on the substance to be purified. Exemplarily, the substance to be purified can be oil fume steam or other substances, and this embodiment does not make any limitation thereto. The following content of this embodiment will take the oil fume steam as an example of the substance to be purified for illustration.

[0042] As Figures 1 to 3 shown, the purification device includes a purification box body 100, a spray assembly 200 and an inlet pipe 600 that are all arranged in the purification box body 100. Among them, the spray assembly 200 is used to spray a purification liquid 1 into the purification box body 100, and the inlet pipe 600 is used to input oil fume steam into the purification box body 100. In this embodiment, the purification liquid 1 in the purification box body 100 can have a certain depth, so that the oil fume steam can precipitate better. The purification liquid is used for adsorbing and purifying the oil fume steam. Exemplarily, the purification liquid can be water or a solution added with cleaning components.

[0043] As Figure 1As shown, the spraying assembly 200 includes a spray head 210, and the spray head 210 is adjustably disposed in the purification box body 100, that is, the spray head 210 is movably disposed in the purification box body 100. The adjustable position of the spray head 210 in the purification box body 100 enables the spray head 210 to move closer to or away from the inflow pipe 600, so that the distance between the spray head 210 and the inflow pipe 600 is adjustable.

[0044] When using the purification device provided in this embodiment, the spray head 210 is adjustably disposed in the purification box body 100. When the flow rate of the oil fume steam at the outlet 610 of the inflow pipe 600 is low, the spray head 210 can be adjusted to move closer to the inflow pipe 600, so that the purification liquid sprayed by the spray head 210 can better mix with the oil fume steam discharged from the outlet 610 of the inflow pipe 600, thereby improving the purification effect on the oil fume steam. When the flow rate of the oil fume steam at the outlet 610 of the inflow pipe 600 is very high, in order to prevent the high-speed oil fume steam from hitting the spray head 210 and affecting the effect of the purification liquid sprayed by the spray head 210, the spray head 210 can be adjusted to move away from the inflow pipe 600, thereby reducing the adhesion of the oil fume steam on the surface of the spray head 210 and reducing the cleaning frequency of the spray head 210.

[0045] In the purification device provided in this embodiment, the spraying assembly 200 and the inflow pipe 600 are both disposed in the purification box body 100, and the spray head 210 of the spraying assembly 200 is adjustably disposed in the purification box body 100, so that the distance between the spray head 210 and the inflow pipe 600 is adjustable. According to different application scenarios, the distance between the spray head 210 and the inflow pipe 600 is adjusted, so that the spray head 210 can be more flexible and can also improve the purification and absorption effect on the object to be purified.

[0046] In some alternative embodiments, the purification device further includes a driving member 300. The driving member 300 is connected to the spray head 210 and is used to drive the spray head 210 to move in the purification box body 100 to realize the adjustable position of the spray head 210 in the purification box body 100. In some alternative embodiments, the driving member 300 is disposed in the purification box body 100. By providing the driving member 300, the automatic driving of the spray head 210 is realized, the automation degree of the purification device is improved, and the displacement accuracy of the spray head 210 is also ensured. For example, the driving member 300 can be a linear driving component such as an electric push rod, a cylinder, or a linear motor, and this embodiment does not limit this.

[0047] Optionally, as Figure 1 shown, the spraying assembly 200 further includes a telescopic pipe 220 connected to and communicating with the spray head 210, wherein the axial dimension of the telescopic pipe 220 is variable to cooperate with the movement of the spray head 210.

[0048] Specifically, one end of the telescopic pipe 220 is located inside the purification box body 100 and is connected and communicated with the spray head 210. The other end of the telescopic pipe 220 extends outside the purification box body 100 and is communicated with the liquid box 60 storing the purification liquid 1, so as to be able to input the purification liquid into the spray head 210. The purification liquid 1 with a certain pressure flows through the telescopic pipe 220 and then enters the spray head 210 and is sprayed out by the spray head 210. When the driving member 300 drives the spray head 210 to move, the spray head 210 drives the telescopic pipe 220 to expand and contract along its axial direction. By arranging the telescopic pipe 220, the spray head 210 can still maintain the communication state with the liquid box 60 after the position changes, thereby ensuring the normal operation of the spray assembly 200.

[0049] In some alternative embodiments, please continue to refer to Figure 1 , the telescopic pipe 220 includes a connected telescopic section 221 and a pipe joint 222. The telescopic section 221 is telescopically arranged inside the purification box body 100, and one end of the telescopic section 221 is connected and communicated with the spray head 210. The other end of the telescopic section 221 is connected and communicated with the pipe joint 222. The pipe joint 222 is arranged on the box wall of the purification box body 100 and extends outside the purification box body 100. The pipe joint 222 is used to be connected with the liquid inlet pipe 30, so as to be communicated with the liquid box 60 through the liquid inlet pipe 30.

[0050] By arranging the telescopic section 221 inside the purification box body 100, when the size of the telescopic section 221 changes, it will not affect the sealing of the purification box body 100. The pipe joint 222 is a straight pipe section, and the pipe joint 222 is arranged on the box wall of the purification box body 100 to facilitate the sealing between the pipe joint 222 and the box wall of the purification box body 100.

[0051] In some embodiments, as Figure 2 shown, the telescopic section 221 is spiral and located inside the purification box body 100; in some other alternative embodiments, the telescopic pipe 220 can be a telescopic pipe, a bellows pipe, etc., and the present embodiment does not limit this.

[0052] Optionally, as Figure 1 shown, the purification device further includes a second sealing structure 500. The box wall of the purification box body 100 is provided with a second through hole 120. The pipe joint 222 passes through the second through hole 120, and the second sealing structure 500 is hermetically arranged between the hole wall of the second through hole 120 and the pipe joint 222, and is used to seal the gap between the hole wall of the second through hole 120 and the pipe joint 222, thereby ensuring the sealing performance of the purification box body 100 and the purification device.

[0053] It should be noted that the pipe joint 222 can be fixedly arranged on the purification box body 100 through the second sealing structure 500. For example, the second sealing structure 500 is clamped on the box wall of the purification box body 100, and the pipe joint 222 is fixed by the frictional force between the pipe joint 222 and the second sealing structure 500, thereby realizing the fixation of the spraying assembly 200.

[0054] Exemplarily, the second sealing structure 500 is a sealing ring, and the sealing ring is sleeved outside the pipe joint 222.

[0055] Optionally, please continue to refer to Figure 2 and Figure 3 , a limiting protrusion 230 is arranged on the outer wall of the pipe joint 222. The limiting protrusion 230 is located outside the purification box body 100, and the radial length of the limiting protrusion 230 is greater than the aperture of the second through hole 120, so as to limit the minimum length of the part of the pipe joint 222 located outside the purification box body 100. When the spray head 210 moves, the pipe joint 222 will not completely enter the purification box body 100 under the pulling of the spray head 210, but always has a part located outside the purification box body 100, ensuring the normal use of the spraying assembly 200 and improving the reliability of the purification device.

[0056] Exemplarily, the limiting protrusion 230 is annular, so that there is a large contact area between the limiting protrusion 230 and the box wall of the purification box body 100, further reducing the possibility of the limiting protrusion 230 passing through the second through hole 120.

[0057] Optionally, the limiting protrusion 230 and the telescopic pipe 220 are of an integrally formed structure to have a high connection strength.

[0058] Optionally, as Figure 1 shown, the driving member includes a connected driving main body 310 and an output end 320. The driving main body 310 is arranged on the box wall of the purification box body 100 and extends outside the purification box body 100. The output end 320 is movably arranged inside the purification box body 100 and is connected to the spray head 210.

[0059] Further optionally, please continue to refer to Figure 1 , the purification device further includes a first sealing structure 400. A first through hole 110 is provided on the box wall of the purification box body 100. The driving main body 310 passes through the first through hole 110, and the first sealing structure 400 is hermetically arranged between the hole wall of the first through hole 110 and the driving main body 310, and is used to seal the gap between the hole wall of the first through hole 110 and the outer side wall of the driving main body 310, improving the sealing performance of the purification device and avoiding affecting the sealing performance of the purification device due to the setting of the driving member 300. Exemplarily, the first sealing structure 400 can be a sealing ring, and the sealing ring is sleeved outside the driving main body 310.

[0060] It should be noted that the driving member 300 can be fixedly arranged on the purification box body 100 through the first sealing structure 400. For example, the first sealing structure 400 is clamped on the box wall of the purification box body 100, and the driving member 300 is fixed by the frictional force between the driving main body 310 and the second sealing structure 500.

[0061] Optionally, as Figure 2 shown, the spraying assembly 200 is arranged on an end wall of the purification box body 100 that is inclined relative to the liquid level of the purification liquid, so as to improve the supporting effect of the end wall on the spraying assembly 200, reduce the probability of the spraying assembly 200 shaking, and improve the stability of the connection between the spraying assembly 200 and the purification box body 100.

[0062] Exemplarily, as Figure 1 shown, one end of the purification box body 100 includes a vertical end wall 101 vertically connected to the bottom wall of the purification box body 100 and an inclined end wall 102 inclined relative to the vertical end wall 101. The inclined end wall 102 is inclined relative to the liquid level of the purification liquid. Specifically, the inclined end wall 102 inclines towards the inside of the purification box body 100, and the spraying assembly 200 is installed on the inclined end wall 102, that is, the second through hole 120 is opened on the inclined end wall 102 to improve the supporting effect of the inclined end wall 102 on the spraying assembly 200.

[0063] Exemplarily, the first through hole 110 is also arranged on the inclined end wall 102, so that the driving member 300 can be supported and fixed through the inclined end wall 102, improving the stability of the installation of the driving member 300 on the purification box body 100.

[0064] In this embodiment, as Figure 1 shown, the purification box body 100 includes a box body 130, a box cover 150 and a gasket 140. The box body 130 is connected to the box cover 150, and the gasket 140 is located between the box body 130 and the box cover 150 for sealing the gap therebetween. The inflow pipe 600 is arranged on the box cover 150. In some embodiments, the inflow pipe 600 is arranged perpendicular to the box cover 150.

[0065] Further optionally, as Figure 2 shown, the outlet 610 of the inflow pipe 600 located inside the purification box body 100 faces the spray head 210 and is inclined relative to the liquid level of the purification liquid 1, so that the outlet 610 has a larger spraying area, further improving the spraying efficiency of the oil fume vapor.

[0066] The spray head 210 in this embodiment has a purification position and a cleaning position, wherein, Figure 2 is a schematic diagram when the spray head 210 is in the purification position, Figure 3 is a schematic diagram when the spray head 210 is in the cleaning position. When the spray head 210 is in the purification position, as Figure 2As shown, the spray head 210 is located above the purification liquid 1 and is oppositely arranged with the outlet 610 of the inlet pipe 600. For example, the outlet 610 and the spray head 210 are oppositely arranged in the center line direction of the outlet 610, so that the oil fume vapor ejected from the outlet 610 can fully contact and mix with the purification liquid 1 ejected from the spray head 210. When the spray head 210 is in the cleaning position, as Figure 3 shown, the spray head 210 contacts the purification liquid 1 in the purification box body 100, so that the purification liquid 1 can be used for cleaning the spray head 210, improving the convenience of cleaning the spray head 210.

[0067] It should be noted that the positions of the cleaning position and the purification position relative to the purification box body 100 can be adjusted according to actual needs, and this embodiment does not limit this. There can be multiple purification positions in this embodiment. In other words, all positions that satisfy the spray head 210 being located above the purification liquid 1 and being oppositely arranged with the outlet 610 of the inlet pipe 600 can be purification positions. The driving member can drive the spray head 210 to move between multiple purification positions, so that the spray head 210 moves closer to or farther away from the inlet pipe 600.

[0068] In this embodiment, the driving member 300 drives the spray head 210 to move between the cleaning position and the purification position, realizing the multiple uses of the driving member 300 and blocking the function of the driving member 300.

[0069] Specifically, after the spray head 210 is used for a long time, oil stains will adhere to the surface of the spray head 210, thereby affecting the spraying of the purification liquid 1 by the spray head 210. The purification liquid 1 in the purification box body 100 has components that can decompose oil stains. By controlling the contact between the spray head 210 and the purification liquid 1 for a period of time, the purification liquid 1 can decompose the oil stains on the surface of the spray head 210. At the same time, when the spray head 210 is in the spraying state, it will vibrate. The vibration of the spray head 210 and the decomposition of the purification liquid 1 act on the oil stains on the spray head 210 simultaneously, so that the oil stains can be removed smoothly, realizing the cleaning of the spray head 210.

[0070] For the purification device provided in this embodiment, when the spray head 210 is working normally, the position of the spray head 210 can be adjusted to be located above the purification liquid 1, that is, in the purification position, so that the spray head 210 does not contact the purification liquid 1. When the spray head 210 needs to be cleaned, the spray head 210 can be adjusted to contact the purification liquid 1, that is, the spray head 210 is in the cleaning position. Through the soaking and decomposition of the oil stains on the spray head 210 by the purification liquid 1, the removal of the oil stains on the spray head 210 can be realized, and then the cleaning of the spray head 210 can be realized. There is no need to disassemble the purification box body 100, nor to disassemble the spray assembly 200 from the purification box body 100, which will not affect the sealing performance of the purification device, reduce the steps of cleaning the spray head 210, and improve the cleaning efficiency.

[0071] Exemplarily, the spray head 210 can be immersed in the purification liquid 1 to improve the cleaning effect. Of course, it can be understood that it can also be that the surface of the spray head 210 where the spray holes are provided is in contact with the purification liquid 1, and other parts are not in contact with the purification liquid 1. This embodiment does not limit this.

[0072] Optionally, the axis of the spray head 210 is perpendicular to the inclined end wall 102, and the spray head 210 is adjustably arranged in the purification box body 100 along the direction of its axis, so as to facilitate the spray head 210 to move towards the direction close to the purification liquid 1, and further facilitate the contact between the spray head 210 and the purification liquid 1.

[0073] When it is necessary to clean the spray head 210 provided in this embodiment, control the driving member 300 to start. The output end 320 of the driving member 300 drives the spray head 210 to move from the purification position to the cleaning position until the spray head 210 is located at the cleaning position. At this time, the purification liquid 1 immerses the spray head 210 to be able to decompose the oil stains on the spray head 210. The spray head 210 can be located at the cleaning position for a preset time duration, and during this process, the spray head 210 continuously sprays the purification liquid 1, so that the spray head 210 can vibrate, which helps to remove the oil stains.

[0074] Optionally, the purification device further includes a liquid level detection component 700, a third sealing structure 800, a primary filter screen 910 and a secondary filter screen 920. The liquid level detection component 700 is installed on the box cover 150, and the third sealing structure 800 is used to seal the gap between the liquid level detection component 700 and the hole wall on the box cover 150 to ensure the sealing performance of the purification box body 100. The primary filter screen 910 and the secondary filter screen 920 are both arranged in the purification box body 100 and are used to filter the purification liquid 1 in the box body.

[0075] This embodiment also provides a cooking appliance, including the above purification device. The cooking appliance provided in this embodiment is easy to clean and has a high cleaning efficiency. The cooking appliance provided in this embodiment includes, but is not limited to, an oven, a steam box, a steam oven combination, etc.

[0076] As Figure 4 shown, the cooking appliance further includes an inner container (not shown), and the inlet pipe 600 communicates with the purification box body 100 and the inner container, so that the oil fume steam generated in the inner container can enter the purification box body 100 through the inlet pipe 600.
