[0043] The present application will be further described below in conjunction with the accompanying drawings and specific embodiments: Figures 1-7

[0044] ​​First of all, it needs to be explained here: in the description of the present application, if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and other orientation words appear, the orientation or position relationship indicated thereby is based on the orientation or position relationship shown in the drawings, and is only for the convenience of description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application; in addition, if the terms "first", "second", "third" and the like appear, they are only for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the present application, unless otherwise explicitly specified and limited, if the terms "mounting", "connecting", "connecting" appear, they should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, interference fit, transition fit and other limit connection, or integral connection; it can be directly connected, or indirectly connected through an intermediate medium; therefore, for those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] As shown in Figures 1 to 7 A mouthpiece assembly, comprising: a main body 2, a filter screen 3, a shielding plate 4, the main body 2 has a smoke inlet 21 on the front side and a smoke outlet 22 located at the lower part of the main body 2, the lower part of the main body 2 has a plate body 23 constituting the lower boundary of the smoke inlet 21; the filter screen 3 is fixed on the front side of the main body 2 and shields part of the smoke inlet 21, the lower end of the filter screen 3 is provided with an abutting portion 31, at least one magnetic component 311 is fixed on the abutting portion 31; the shielding plate 4 is located at the lower part of the filter screen 3, the shielding plate 4 comprises a main plate 41, side edges 42 located on both sides of the main plate 41, a limiting portion 43 located at the lower part of the main plate 41, a clamping groove 421 is arranged in the middle of the side edge 42, a positioning shaft 5 is fixed on the side wall 25 of the main body 2, the shielding plate 4 is clamped on the positioning shaft 5 through the clamping groove 421, so that the shielding plate 4 can rotate relative to the positioning shaft 5, the shielding plate 4 can be separated from the positioning shaft 5, the limiting portion 43 is connected to the lower end of the side edge 42 at both ends and forms a containing groove 44; wherein the shielding plate 4 can rotate between a first position and a second position; in the first position, the upper end of the shielding plate 4 can abut on the abutting portion 31 and be magnetically connected with the magnetic component 311, the limiting portion 43 at the lower part of the shielding plate 4 can abut on the plate body 23; in the second position, a gap 6 is formed between the upper end of the shielding plate 4 and the abutting portion 31, and the limiting portion 43 at the lower part of the shielding plate 4 abuts on the rear wall 24 of the main body 2 and closes the smoke outlet 22 of the main body 2.

[0046] In the present application, under normal working conditions, the shielding plate 4 is in the first position, and the shielding plate 4 is clamped on the positioning shaft 5 fixed on the side wall 25 of the main body 2 through the clamping groove 421 in the middle of the two side edges 42 of the shielding plate 4, realizing the rotatable connection with the main body 2. At this time, the upper end of the shielding plate 4 can abut against the abutting portion 31 at the lower end of the filter screen 3, and is magnetically connected by means of at least one magnetic component 311 fixed on the abutting portion 31, thereby ensuring the stable fixing of the upper end of the shielding plate 4, and at the same time, the limiting portion 43 of the lower part of the shielding plate 4 can abut against the plate body 23 constituting the lower boundary of the smoke inlet 21. Such a design enables the shielding plate 4 to play a certain shielding and protection role on the area below the smoke inlet 21 when the shielding plate 4 is in the first position, preventing the abnormal flow or leakage of oil fume in this area, and ensuring that the oil fume can flow more smoothly through the smoke inlet 21 into the main body 2 and then be discharged from the smoke outlet 22 at the lower part of the main body 2 after being treated.

[0047] When certain specific operations such as cleaning and maintenance are required, the shielding plate 4 can be rotated from the first position to the second position. During the rotation process, the shielding plate 4 rotates around the positioning shaft 5, and when it reaches the second position, a gap 6 is formed between the upper end of the shielding plate 4 and the abutting portion 31, so that the area originally shielded by the shielding plate 4 is opened, facilitating related operations such as cleaning of the filter screen 3 and other components. At the same time, the limiting portion 43 of the lower part of the shielding plate 4 abuts against the rear wall 24 of the main body 2 and closes the smoke outlet 22 of the main body 2. This step is mainly to prevent external impurities, tools, cleaning agents, etc. from entering the main body 2 through the smoke outlet 22 when performing specific operations, so as to ensure that the internal environment of the main body 2 is relatively closed, and to avoid unnecessary pollution or interference during maintenance and cleaning.

[0048] The design of the shielding plate 4 clamped on the positioning shaft 5 through the clamping groove 421 enables the shielding plate 4 to rotate relative to the positioning shaft 5 to adapt to different working conditions and operation requirements, and also enables the shielding plate 4 to be separated from the positioning shaft 5, so that the shielding plate 4 can be completely disassembled for more thorough cleaning or component replacement when needed. This combination of detachable and rotatable connection greatly improves the maintainability of the whole head assembly. The shielding plate 4 plays different protection roles in different positions. In the first position, it protects the area below the smoke inlet 21 to ensure normal flow of oil fume; in the second position, it closes and protects the smoke outlet 22 to prevent external impurities from entering the main body 2. This multi-directional protection function enables the head assembly to better protect the internal environment and ensure the working effect during the whole working process and maintenance stage.

[0049] The rotation operation of the shielding plate 4 between the first position and the second position is relatively simple, and only needs to apply appropriate external force to rotate it around the positioning shaft 5 to complete the position conversion.

[0050] Specifically, asFigure 2 、 Figure 3 、 Figure 4 As shown, the rear wall 24 of the main body 2 has a convex cavity 241 protruding toward the rear side, and the convex cavity 241 has a first wall 2411 and a second wall 2412. The second wall 2412 is vertically arranged, and the first wall 2411 and the second wall 2412 form an angle α, and the angle α is 150°-170°. In the first position, the first wall 2411 is parallel to the filter 3, and the second wall 2412 is parallel to the main board 41 of the baffle 4.

[0051] During the operation of the integrated stove, the oil smoke needs to flow along a specific path inside the main body 2 so as to be efficiently inhaled.

[0052] When in the first position, the first wall 2411 is parallel to the filter 3, and the second wall 2412 is parallel to the main plate 41 of the shielding plate 4. This parallel relationship allows the oil smoke, after passing through the filter 3, to continue flowing in a direction that is more aligned with the first wall 2411 and the second wall 2412. This is like laying a "track" for the oil smoke, allowing it to flow more smoothly and naturally, reducing resistance caused by sudden changes in direction or airflow turbulence, thereby improving the efficiency of oil smoke exhaust.

[0053] Specifically, if Figures 1-7 As shown, it also includes a storage rack 7, at least two hand-tightening nuts 8 are threadedly connected to the first wall 2411, and the storage rack 7 includes a storage plate 71 and a connecting frame 72. The connecting frame 72 is fixed to the lower plate surface of the storage plate 71, and the connecting frame 72 has a connecting wall 721. The connecting wall 721 can be tightly attached to the first wall 2411, and the storage plate 71 remains in a horizontal state. A bayonet 7211 is provided on the connecting wall 721, and the bayonet 7211 is provided on the hand-tightening nut 8. The front end of the storage plate 71 is against the top of the main body 2, and the rear end of the storage plate 71 does not exceed the upward extension line of the second wall 2412.

[0054] The rack 7 is installed by engaging at least two hand-tightening nuts 8 threadedly connected on the first wall 2411 with the bayonet holes 7211 on the rack 7 connecting frame 72. This installation method does not require complicated tools. The user simply needs to manually tighten the hand-tightening nuts 8 and snap them into the bayonet holes 7211 on the connecting wall 721 to complete the installation. This simple and quick operation can be easily completed by even non-professionals, greatly reducing the difficulty of installation and improving the convenience of users when installing or removing the rack 7.

[0055] The cooperation of the multiple hand nuts 8 and the bayonet 7211 forms a multi-point connection between the rack 7 and the first wall 2411 of the main body 2. Compared with a single-point connection, this multi-point connection can more evenly distribute the weight of the items carried by the rack 7.

[0056] The connecting wall surface 721 of the connecting frame 72 can be tightly attached to the first wall 2411, further enhancing the stability of the storage rack 7 during use, ensuring that the storage rack 7 can remain stable when placing items and will not easily sway or tip over.

[0057] The front end of the storage plate 71 abuts against the top of the main body 2, and the rear end does not exceed the upward extension line of the second wall 2412. Such a design makes the layout of the storage rack 7 in space very reasonable, which fully utilizes the space near the cavity 241 of the convex portion of the rear wall 24 of the main body 2, and will not cause space waste or interference with other components due to the excessive size of the storage rack 7.

[0058] Specifically, as shown in Figure 2 , the two ends of the filter screen 3 abut against the rear wall 24 of the main body 2.

[0059] When the two ends of the filter screen 3 abut against the rear wall 24 of the main body 2, a stable support structure is formed. At this time, the abutting relationship between the filter screen 3 and the rear wall 24 of the main body 2 can better resist these external forces and reduce displacement caused by external forces.

[0060] Specifically, as shown in Figure 3 , Figure 4 , two connecting ears 32 are arranged on the filter screen 3, which are distributed at the two ends of the abutting portion 31. The side wall 25 of the main body 2 is provided with screw holes 251 corresponding to the connecting ears 32. In the first position, the shielding plate 4 can shield the connecting ears 32.

[0061] The connecting ears 32 on the filter screen 3 and the corresponding screw holes 251 on the side wall 25 of the main body 2 can be stably connected through bolts or other connecting members. This connection method makes the installation of the filter screen 3 on the front side of the main body 2 more firm. In the first position, the shielding plate 4 can shield the connecting ears 32, making the appearance of the whole head assembly more tidy and unified.

[0062] Specifically, in the first position, the lower end of the filter screen 3 is farther away from the outer edge 252 of the side wall 25 of the main body 2 than the upper end of the filter screen 3. The upper end of the shielding plate 4 is farther away from the outer edge 252 of the side wall 25 of the main body 2 than the lower end of the shielding plate 4. The filter screen 3, the shielding plate 4, and the side wall 25 of the main body 2 form a smoke gathering area 9. The outer edge 252 of the side wall 25 is the edge portion of the side wall 25 of the main body 2 away from the rear wall 24.

[0063] In the working process of the integrated cooker, the oil fume generated will spread within a certain range, and at this time, the lower end of the filter screen 3 is farther away from the outer edge 252 of the side wall 25 of the main body 2 than the upper end, the upper end of the shielding plate 4 is farther away from the outer edge 252 of the side wall 25 of the main body 2 than the lower end, and the side wall 25 of the main body 2, together, form the smoke gathering area 9. The special shape and layout make the oil fume be effectively gathered in the area. After the oil fume enters the area, the formation of the smoke gathering area 9 plays a guiding role in the direction of the oil fume flow, which is more easily sucked in by being blocked by the two side walls 25.

[0064] In the prior art, the oil fume is easy to disperse to the two sides after contacting the top.

[0065] At the same time, the design can leave more space in the front side area of the head assembly. The shielding plate 4 and the filter screen 3 are recessed towards the inside, which is roughly corresponding to the height of the frying pan. When the frying pan is flipped, more space is left for the flipping of the frying pan.

[0066] An integrated cooker comprising the above head assembly.

[0067] A cleaning method of a head assembly, comprising the following steps:

[0068] S1, ensuring that the power of the integrated cooker is turned off and the equipment is fully cooled to room temperature;

[0069] In step S1, it is clearly required to ensure that the power of the integrated cooker is turned off and the equipment is fully cooled to room temperature. This is the first step of the whole cleaning process. By turning off the power, the safety risk of electric shock and scalding of the operator caused by accidental touch of the switch or electrical failure can be completely eliminated. Cooling the equipment to room temperature avoids the possibility of scalding the operator by high-temperature components, and provides a safe and reliable environment for subsequent cleaning operations, fully ensuring the personal safety of the operator during the cleaning process.

[0070] S2, precisely acting on the lower end of the shielding plate 4, and continuously applying the pressure until the shielding plate 4 is accurately rotated to the second position. At this time, a specific gap 6 will be formed between the upper end of the shielding plate 4 and the abutting part 31 of the lower end of the filter screen 3, and the limiting part 43 of the lower part of the shielding plate and the rear wall 24 of the main body 2 are in close abutting state, so as to ensure that the smoke outlet 22 of the lower part of the main body 2 is closed;

[0071] In step S2, the lower end of the shielding plate 4 is precisely acted on and a moderate and uniform manual pressure is applied to facilitate rotation thereof. This precise and standardized operation mode helps to avoid damage to the shielding plate 4 and the connecting structure of the shielding plate 4 and the side wall 25 of the main body 2 due to excessive force, uneven force or improper operation, and the shielding plate 4 is rotated to the accurate position through a smooth rotation movement, which not only ensures that the shielding plate 4 can be switched to the second position for easy cleaning, but also maintains the structural integrity of the shielding plate 4 and related components, thereby prolonging the service life of the components.

[0072] S3, cleaning the inner wall of the main body 2;

[0073] During the cleaning process, the internal cleaning agent can be received through the accommodating groove 44 on the shielding plate 4, thereby reducing the entry of the cleaning agent and oil into the volute.

[0074] S4, when the cleaning operation of the main body 2 is completed, the shielding plate 4 is disassembled and cleaned to ensure that the shielding plate 4 returns to a clean state that meets the requirements for reuse after cleaning;

[0075] During the entire cleaning process, by rotating the shielding plate 4 to the second position and closing the smoke outlet 22, the shielding plate 4 is disassembled and cleaned separately after the interior is cleaned, thereby avoiding secondary pollution.

[0076] S5, after the shielding plate 4 is cleaned and meets the cleaning standards, the shielding plate 4 is reinstalled on the positioning shaft 5 of the side wall 25 of the main body 2 according to the correct installation steps, so as to smoothly and accurately rotate the shielding plate 4 from the second position to the first position, and realize stable magnetic attraction connection with the magnetic component 311 fixed on the abutting portion 31; at the same time, the limiting portion 43 of the lower portion of the shielding plate 4 abuts on the plate body 23 constituting the lower boundary of the smoke inlet 21 again.

[0077] It should be noted that the above embodiments are only used to illustrate the technical solutions described in the present application and not to limit the technical solutions described in the present application. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the skilled in the art can still modify or equivalently replace the present application, and all technical solutions and improvements that do not deviate from the spirit and scope of the present application should be covered in the scope of the claims of the present application.
