Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to a cooking utensil. Background Art

[0002] Cooking appliances (such as rice cookers, pressure cookers, etc.) include an outer cover and an internal heat preservation cover assembly. The heat preservation cover assembly generally needs to be fixed to the base of the outer cover to ensure its assembly stability. In order to facilitate the fixation of the heat preservation cover assembly and the arrangement of components such as the pressure switch at the bottom of the heat preservation cover assembly, an opening is provided at the bottom of the outer cover. The assembler fixes the heat preservation cover assembly, arranges the internal wiring harness, and adjusts the pressure of the pressure switch through the opening. Finally, the bottom plate is fixed to the bottom of the outer cover, and the opening is closed to complete the assembly.

[0003] However, the bottom opening of the outer cover is mostly circular. When the machine is small, such as a 2L or 3L machine, the bottom space is often very small, and the bottom opening of the outer cover becomes smaller, resulting in less space for assembly personnel to operate, which is not conducive to assembly operations, resulting in low production efficiency of the production line. In addition, the shape of the bottom plate is adapted to the shape of the circular opening, which is also circular, making it difficult to position the circular bottom plate during assembly. During assembly, the assembler needs to identify the position of the screw holes or certain specific structures to snap them together, which also reduces the assembly efficiency invisibly.

[0004] In addition, the base plate of a small-capacity cooking appliance is also small in size. When the base plate is fixed to the bottom of the outer cover, it is difficult for the base plate to effectively cover the fixing holes, screws and other fixing parts on the outer cover or the insulation cover assembly, leaving part of the fixing structure exposed, affecting the appearance quality of the entire machine and giving users a poor product experience. Utility Model Content

[0005] The utility model provides a cooking utensil to solve the problems that the opening at the bottom of the existing small-capacity cooking utensil is small, the operating space is limited, resulting in greater difficulty in assembly, and the bottom plate is difficult to position during assembly, resulting in low assembly efficiency, and the bottom plate is difficult to effectively shield the fixed structure.

[0006] The technical solution adopted by the utility model is:

[0007] A cooking utensil comprises an outer shell and a base plate, wherein a mounting opening is provided at the bottom of the outer shell, and the base plate covers the mounting opening. A mounting platform is provided at the bottom of the outer shell, and the mounting opening is provided at the mounting platform. At least one side of the mounting platform extends radially outwardly along the outer shell to form a fixed position, and the base plate is provided with a laterally protruding positioning skirt corresponding to the fixed position, and the positioning skirt cooperates with the fixed position to position the base plate.

[0008] The cooking utensil of the present invention also has the following additional technical features:

[0009] The edge of the mounting opening has a flared portion protruding laterally toward the outside of the mounting opening, and a mounting portion protruding laterally toward the inside of the mounting opening. The mounting portion is provided with a fixing hole. When the bottom plate is fixed to the shell, the bottom plate covers the fixing hole.

[0010] The flared portion and the mounting portion are both located in the fixed position.

[0011] The cooking appliance further comprises a heat-insulating cover arranged inside the shell, the bottom wall of the heat-insulating cover is provided with a fixing part and a pressure switch, the fixing part is arranged corresponding to the fixing hole, and the pressure switch is located in the flared part.

[0012] A fixing buckle is arranged in the installation sink, and a matching part is arranged on the peripheral side of the base plate. The base plate can be rotated in the installation sink to have an unlocked state in which the fixing buckle is loose from the matching part, and a locked state in which the fixing buckle is screwed with the matching part.

[0013] The edge of the positioning skirt has a contact arc surface, and the side wall of the mounting sink has a matching arc surface at the outer edge of the fixed position, and the curvature of the matching arc surface is smaller than that of the contact arc surface; or, the matching arc surface has a first arc segment and a second arc segment, and when the base plate is in the unlocked state, the contact arc surface is tangent to the first arc segment, and when the base plate is in the locked state, the contact arc surface is tangent to the second arc segment.

[0014] The fixing positions are located at two opposite sides of the installation opening, the bottom plate comprises a main body, and the positioning skirt is arranged at two opposite sides of the main body along the radial direction of the main body.

[0015] The bottom of the shell is also provided with a plurality of supporting feet, which are spaced apart along the circumference of the shell and staggered with the fixing position.

[0016] The shell is provided with a wire channel, and the edge of the installation opening is also provided with a wire passing notch connected to the wire channel. The wire passing notch is staggered with the fixing position. When the bottom plate is fixed to the shell, the bottom plate blocks the wire passing notch.

[0017] The base plate also includes a body, the positioning skirt is located at the periphery of the body, the body has a central area and an edge area surrounding the periphery of the central area, the central area is provided with a first air inlet hole, and the edge area is provided with a second air inlet hole.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0019] 1. In the utility model, a mounting platform is provided at the bottom of the shell, and the mounting opening is provided inside the mounting platform, so that when the bottom plate is assembled, it can cooperate with the mounting platform to form a lateral positioning of the bottom plate, and at the same time, it can ensure that the mounting opening is fully covered after the bottom plate is assembled in place. In addition, the mounting platform extends outward to form a fixed position, and the edge of the bottom plate protrudes laterally to form a positioning skirt, so that the mounting platform and the bottom plate are a non-circular structure as a whole, and the shapes of the two are adapted, thereby playing a circumferential positioning role in the assembly of the bottom plate. The assembler can put the positioning skirt into the fixed position to complete the positioning of the bottom plate. Compared with both being circular, the assembler can simply and clearly select the reference position and quickly complete the positioning and matching of the two, thereby greatly reducing the difficulty of assembling the bottom plate and improving the assembly efficiency of the bottom plate.

[0020] In addition, since the installation sink extends laterally to form a fixed position, the area of ​​the installation sink is increased, which helps to expand the installation opening outward at the position corresponding to the fixed position to increase the area of ​​the installation opening. Especially for small-capacity cooking utensils, it is more convenient for assemblers to fix the shell and the insulation cover and adjust the pressure, thereby further improving the assembly efficiency. Moreover, the fixed position also provides a larger installation space for fixing the shell and the insulation cover. The fixed structure can be set in the fixed position, so that the fixed structure does not need to occupy the space inside the installation opening, which improves the flexibility of the fixed structure arrangement position, facilitates the fixing of the shell and the insulation cover, and also ensures the area of ​​the installation opening, which is convenient for wiring and other assembly operations. Since the bottom plate is provided with the positioning skirt corresponding to the fixed position, after the bottom plate is assembled, even if the fixed structure is set in the fixed position, the positioning skirt can also form a certain shielding for the fixed position, so that the fixed structure will not be exposed, ensuring the appearance quality of the cooking utensil and improving the user experience.

[0021] 2. As a preferred embodiment of the utility model, the edge of the mounting opening has a flared portion that protrudes laterally toward the outside of the mounting opening, and a mounting portion that protrudes laterally toward the inside of the mounting opening, and the mounting portion is provided with a fixing hole, and when the bottom plate is fixed to the shell, the bottom plate blocks the fixing hole. The edge of the mounting opening expands outward to form the flared portion, and the mounting opening is designed to be larger without affecting the position of the supporting feet at the bottom of the shell. At the same time, the mounting portion protrudes toward the inside of the mounting opening to fix the thermal insulation cover, leaving enough operating space for the assemblers, and the bottom plate can be used to cover it. Such a design can not only allow the assemblers to have a larger space for wire arrangement, voltage adjustment and other operations during assembly, thereby improving assembly efficiency, but also cover the fixing holes while facilitating the fixing of the thermal insulation cover, thereby beautifying the appearance of the entire machine, achieving multiple goals at one stroke.

[0022] 3. As a preferred embodiment of the utility model, a fixing buckle is provided in the installation sink, and a matching part is provided on the peripheral side of the base plate, and the base plate can rotate in the installation sink to have an unlocked state in which the fixing buckle is loose from the matching part, and a locked state in which the fixing buckle is screwed with the matching part. The base plate and the shell are screwed together and fixed, which not only realizes the rapid assembly and disassembly of the two, saves assembly and disassembly time, and improves assembly efficiency, but also reduces the assembly difficulty of the base plate by the screwing and fixing method. At the same time, the processing of the fixing buckle and the matching part is relatively simple, and the stability of the two after the cooperation is also relatively high, which can further improve the assembly efficiency and save production costs.

[0023] 4. As a preferred embodiment of the present invention, the edge of the positioning skirt has a contact arc surface, and the side wall of the mounting sink has a matching arc surface at the outer edge of the fixed position, and the curvature of the matching arc surface is smaller than that of the contact arc surface. When assembling the base plate, first place the base plate into the mounting sink so that the positioning skirt is located in the fixed position, and then rotate the base plate so that the fixing buckle and the matching portion match. Since the positioning skirt needs to rotate relative to the mounting sink, the mounting boss needs to leave space for the base plate to rotate. By designing the matching arc surface to have a curvature smaller than that of the contact arc surface, the curvature of the matching arc surface is smaller than that of the contact arc surface, thereby forming a space for the positioning skirt to rotate, so that the positioning skirt can rotate between the locked position and the unlocked position without being stopped by the matching arc surface. Only when the positioning skirt is rotated into place, it contacts with the matching arc surface to form a stop, forming a prompt for the base plate to be rotated into place.

[0024] 5. As a preferred embodiment of the present invention, the fixed position is located on two opposite sides of the installation opening, the base plate includes a main body, and the positioning skirt is relatively arranged on both sides of the main body along the radial direction of the main body. The positioning skirts with wing-shaped structures on both sides of the base plate are arranged one-to-one with the fixed positions on both sides of the installation sink, forming positioning and limiting for both sides of the base plate, which not only ensures the accuracy of the positioning of the base plate, but also facilitates fixing on both sides of the base plate, making the base plate more stable and the force on both sides more uniform, avoiding the base plate from tilting. At the same time, during assembly, the assemblers can apply force to the positioning skirts on both sides at the same time to fix the base plate, which improves the operating feel and reduces the difficulty of operation, while also balancing the force on both sides of the base plate, making it convenient for the assemblers to operate.

[0042] like Figure 1 , Figure 2 , Figure 3As shown, a cooking utensil comprises a shell 1 and a base plate 2, wherein a mounting opening 13 is provided at the bottom of the shell 1, and the base plate 2 covers the mounting opening 13, and a mounting sink 11 is provided at the bottom of the shell 1, wherein the mounting opening 13 is provided at the mounting sink 11, and at least one side of the mounting sink 11 extends radially outwardly along the shell 1 to form a fixing position 12, and a laterally protruding positioning skirt 21 is provided on the base plate 2 corresponding to the fixing position 12, and the positioning skirt 21 cooperates with the fixing position 12 to position the base plate 2.

[0043] In the utility model, a mounting platform 11 is provided at the bottom of the housing 1, and the mounting opening 13 is provided inside the mounting platform 11, so that when the bottom plate 2 is assembled, it can cooperate with the mounting platform 11 to form a lateral positioning of the bottom plate 2, and at the same time, it can ensure that the mounting opening 13 is fully covered after the bottom plate 2 is assembled in place. In addition, the mounting platform 11 extends outward to form a fixed position 12, and the edge of the bottom plate 2 protrudes laterally to form a positioning skirt 21, so that the mounting platform 11 and the bottom plate 2 are a non-circular structure as a whole, and the shapes of the two are adapted, so as to play a circumferential positioning role in the assembly of the bottom plate 2. The assembler can put the positioning skirt 21 into the fixed position 12 to complete the positioning of the bottom plate 2. Compared with both being circular, the assembler can simply and clearly select the reference position and quickly complete the positioning and matching of the two, thereby greatly reducing the difficulty of assembling the bottom plate 2 and improving the assembly efficiency of the bottom plate 2.

[0044] In addition, since the installation sink 11 extends laterally to form the fixing position 12, the area of ​​the installation sink 11 is increased, which helps to expand the installation opening 13 outward at the position corresponding to the fixing position 12 to increase the area of ​​the installation opening 13. Especially for small-capacity cooking utensils, it is more convenient for assemblers to fix the shell 1 and the heat preservation cover 3 and adjust the pressure, thereby further improving the assembly efficiency. Moreover, the fixing position 12 also provides a larger installation space for fixing the shell 1 and the heat preservation cover 3. The fixing structure can be set in the fixing position 12, so that the fixing structure does not need to occupy the space inside the installation opening 13, which improves the flexibility of the fixed structure arrangement position, facilitates the fixing of the shell 1 and the heat preservation cover 3, and also ensures the area of ​​the installation opening 13, which is convenient for wiring and other assembly operations. Since the bottom plate 2 is provided with the positioning skirt 21 corresponding to the fixing position 12, after the bottom plate 2 is assembled, even if a fixing structure is set in the fixing position 12, the positioning skirt 21 can form a certain shielding for the fixing position 12 so that the fixing structure will not be exposed, thereby ensuring the appearance quality of the cooking utensil, avoiding contamination of the fixing structure, and improving the user experience.

[0045] Preferably, if Figure 2 As shown, the area of ​​the installation opening 13 is smaller than the area of ​​the installation sink 11, that is, the edge of the installation opening 13 is still a certain distance away from the side wall of the installation sink 11, and the area of ​​the base plate 2 is adapted to the installation sink 11, thereby ensuring that the installation opening 13 can be completely covered after the base plate 2 is assembled.

[0046] As a preferred embodiment of the present invention, Figure 1 , Figure 2 As shown, the edge of the mounting opening 13 has a flared portion 14 that protrudes laterally toward the outside of the mounting opening 13, and a mounting portion 15 that protrudes laterally toward the inside of the mounting opening 13. The mounting portion 15 is provided with a fixing hole 151. When the bottom plate 2 is fixed to the housing 1, the bottom plate 2 blocks the fixing hole 151.

[0047] The edge of the mounting opening 13 expands outward to form the flared portion 14, and the mounting opening 13 is designed to be larger without affecting the position of the supporting feet 17 at the bottom of the housing 1. At the same time, the mounting portion 15 protrudes into the mounting opening 13 to fix the heat preservation cover 3, leaving enough operating space for the assembler.

[0048] It is understandable that the assembly steps of the bottom plate 2 are to first place the bottom plate 2 into the mounting sink 11, so that it cooperates with the mounting sink 11 to form a position, and then fix the bottom plate 2 to the housing 1 by means of snap connection, screws, etc. It should be noted that in this embodiment, it is only necessary to ensure that the bottom plate 2 and the housing 1 are in a fixed state and the fixing hole 151 is blocked. After the bottom plate 2 is placed in the mounting sink 11 and before it is fixed to the housing 1, it may block at least part of the fixing hole 151, or it may not block the fixing hole 151.

[0049] Furthermore, if Figure 2 As shown, the flared portion 14 and the mounting portion 15 are both located in the fixing position 12 .

[0050] The flared portion 14 and the mounting portion 15 are both located in the fixed position 12, which can not only expand the area of ​​the mounting opening 13 and improve the installation space, but also can use the positioning skirt 21 of the wing-shaped structure of the bottom plate 2 to cover it. Such a design can not only allow assemblers to have a larger space for wiring harness arrangement, voltage adjustment and other operations during assembly, thereby improving assembly efficiency, but also can cover the fixing hole 151 while facilitating the fixation of the insulation cover 3, thereby beautifying the appearance of the entire machine and achieving multiple goals at one stroke.

[0051] Preferably, if Figure 4 , Figure 5As shown, the cooking appliance further includes a heat preservation cover 3 disposed inside the outer shell 1 , the bottom wall of the heat preservation cover 3 is provided with a fixing portion 31 and a pressure switch 32 , the fixing portion 31 is arranged corresponding to the fixing hole 151 , and the pressure switch 32 is located in the flared portion 14 .

[0052] The pressure switch 32 is arranged corresponding to the flared portion 14. On the one hand, there is a large operating space at the flared portion 14, and the assembler can easily install the pressure switch 32 and perform pressure adjustment operations, which is less difficult to assemble and improves production efficiency. On the other hand, the pressure switch 32 is deviated from the center of the bottom of the heat preservation cover 3, so as to avoid other components at the bottom of the heat preservation cover 3 (such as the heating device pins, the temperature measuring parts, etc.), so that the structural layout of the bottom of the heat preservation cover 3 is more reasonable, which is convenient for assembly operations.

[0053] Preferably, if Figure 2 , Figure 3 As shown, the fixing position 12 is located at two opposite sides of the installation opening 13 , the bottom plate 2 includes a body 22 , and the positioning skirt 21 is arranged at two opposite sides of the body 22 along the radial direction of the body 22 .

[0054] Specifically, the body 22 is circular, and the positioning skirt 21 is an airfoil structure arranged on both sides of the body 22. There are two flaring parts 14 and two mounting parts 15, and one flaring part 14 and one mounting part 15 are arranged in each fixing position 12. Among them, one flaring part 14 and one mounting part 15 form a component, and one of the above components is arranged on each side of the mounting opening 13, and the two components are centrally symmetrically distributed about the center of the shell 1. The bottom wall of the thermal insulation cover 3 is also provided with two fixing parts 31, which correspond to the fixing holes 151 respectively and are fastened by screws.

[0055] The positioning skirts 21 with wing-shaped structures on both sides of the bottom plate 2 are arranged in a one-to-one correspondence with the fixing positions 12 on both sides of the installation sink 11, forming positioning and limiting positions on both sides of the bottom plate 2, which not only ensures the accuracy of the positioning of the bottom plate 2, but also facilitates fixing on both sides of the bottom plate 2, making the bottom plate 2 more stable and the forces on both sides more uniform, avoiding the bottom plate 2 from tilting. At the same time, during assembly, the assembler can apply force to the positioning skirts 21 on both sides at the same time to fix the bottom plate 2, improve the operating feel, reduce the difficulty of operation, and balance the forces on both sides of the bottom plate 2, making it convenient for the assembler to operate.

[0056] Of course, the number of the fixing positions 12 of the mounting platform 11 may be other numbers, such as one, or more than two. The number of the positioning skirts 21 on the base plate 2 corresponds to the number of the fixing positions 12, which is not limited here.

[0057] It should be noted that the present invention does not limit the fixing method of the bottom plate 2 and the housing 1, and the bottom plate 2 and the housing 1 can be fixed by snap-fit ​​fixing, screw fixing, etc. As a preferred embodiment, Figure 1 , Figure 6 , Figure 7 As shown, a fixing buckle 16 is provided in the mounting sink 11, and a matching portion 23 is provided on the peripheral side of the base plate 2. The base plate 2 can rotate in the mounting sink 11 to have an unlocked state in which the fixing buckle 16 and the matching portion 23 are loose, and a locked state in which the fixing buckle 16 and the matching portion 23 are screwed together.

[0058] The base plate 2 and the shell 1 are screwed and fixed together, which not only realizes the rapid assembly and disassembly of the two, saves assembly and disassembly time and improves assembly efficiency, but also reduces the assembly difficulty of the base plate 2. At the same time, the processing of the fixing buckle 16 and the matching part 23 is relatively simple, and the stability of the two after matching is also relatively high, which can further improve assembly efficiency and save production costs.

[0059] This embodiment does not limit the location of the matching portion 23. In a preferred embodiment, Figure 3 As shown, the bottom plate 2 includes a body 22 and the positioning skirt 21 located on at least one side of the body 22, and the matching portions 23 are arranged at intervals along the circumference of the bottom plate 2 as a whole, that is, the positioning skirt 21 is provided with the matching portions 23, and the body 22 is also provided with the matching portions 23. Of course, the matching portions 23 can also be provided only on the body 22 or the positioning skirt 21, which is not limited here.

[0060] In a specific embodiment, Figure 6 , Figure 7 As shown, the fixing buckle 16 has a transverse snap interface, and the matching portion 23 is a snap notch set at the edge of the bottom plate 2, and the width of the snap notch is greater than the width of the fixing buckle 16. During assembly, the fixing buckle 16 is first passed through the snap notch, and then the bottom plate 2 is rotated so that the edge of one side of the snap notch enters the fixing buckle 16 from the transverse snap interface to complete the snap connection. The matching portion 23 can also be other structures, for example, the matching portion 23 is a matching buckle that can be rotatably matched with the fixing buckle 16, etc., which is not limited here.

[0061] In one embodiment, if Figure 6 , Figure 7 As shown, the edge of the positioning skirt 21 has a contact arc surface 211 , and the side wall of the mounting sink 11 has a matching arc surface 121 at the outer edge of the fixing position 12 , and the curvature of the matching arc surface 121 is smaller than that of the contact arc surface 211 .

[0062] When assembling the base plate 2, first place the base plate 2 into the mounting sink 11 so that the positioning skirt 21 is located in the fixed position 12, and then rotate the base plate 2 so that the fixing buckle 16 and the matching portion 23 match. Since the positioning skirt 21 needs to rotate relative to the mounting sink 11, the mounting boss needs to leave space for the base plate 2 to rotate. By designing the matching arc surface 121 to have an arc smaller than the contact arc surface 211, the curvature of the matching arc surface 121 is smaller than the curvature of the contact arc surface 211, thereby forming a space for the positioning skirt 21 to rotate, so that the positioning skirt 21 can rotate between the locked position and the unlocked position without being stopped by the matching arc surface 121. Only when the positioning skirt 21 is rotated into place, it contacts the matching arc surface 121 to form a stop, forming a prompt for the base plate 2 to rotate into place.

[0063] In another embodiment, the mating arc surface 121 has a first arc segment and a second arc segment. When the base plate 2 is in the unlocked state, the contact arc surface 211 is tangent to the first arc segment. When the base plate 2 is in the locked state, the contact arc surface 211 is tangent to the second arc segment.

[0064] In this embodiment, the matching arc surface 121 is not a continuous arc, but includes multiple arc segments. When the positioning skirt 21 rotates to the unlocked position with the bottom plate 2, the contact arc surface 211 at the edge of the positioning skirt 21 is tangent to the first arc segment, prompting the bottom plate 2 to rotate in place. When the positioning skirt 21 rotates to the locked position with the bottom plate 2, the contact arc surface 211 is tangent to the second arc segment. In this way, the curvature of the first arc segment and the second arc segment can be flexibly set according to the two position states of the positioning skirt 21.

[0065] In a preferred embodiment, Figure 1 , Figure 2 As shown, a plurality of supporting feet 17 are further provided at the bottom of the housing 1 , and the supporting feet 17 are spaced apart along the circumference of the housing 1 and are staggered with the fixing position 12 .

[0066] Since the fixing position 12 extends laterally outward, the support foot 17 is staggered with the fixing position 12, so that the space at the bottom of the outer shell 1 can be more reasonably utilized, the radial dimension of the outer shell 1 can be effectively reduced, and the bottom structure of the outer shell 1 can be more compact. Such a structural arrangement has significant advantages especially in small-capacity cooking utensils.

[0067] Preferably, if Figure 1 , Figure 2 As shown, the housing 1 is provided with a wiring channel 18, and the edge of the mounting opening 13 is also provided with a wire passing notch 19 connected to the wiring channel 18. The wire passing notch 19 is staggered with the fixing position 12. When the bottom plate 2 is fixed to the housing 1, the bottom plate 2 blocks the wire passing notch 19.

[0068] After the heat preservation cover 3 is fixed to the shell 1, the connection wires of each electrical component can be passed from the installation port 13 through the wire notch 19 into the wire harness channel 18. The wire notch 19 is misaligned with the fixed position 12, and the wiring position is also misaligned with the fixed position 12 and the positioning position of the bottom plate 2 to avoid interference and optimize the bottom structure layout of the shell 1. After the bottom plate 2 is fixed to the shell 1, the bottom plate 2 cooperates with the wire notch 19 to form a wire port, so that the two cooperate to form a limit for the wire harness, improve the constraint on the wire harness, and optimize the overall wiring regularity.

[0069] Preferably, if Figure 3 As shown, the base plate 2 also includes a main body 22, the positioning skirt 21 is located on the periphery of the main body 22, the main body 22 has a central area and an edge area surrounding the periphery of the central area, the central area is provided with a first air inlet hole 24, and the edge area is provided with a second air inlet hole 25.

[0070] External air flow can enter the interior of the shell 1 through the first air inlet hole 24 and the second air inlet hole 25 to cool the heat preservation cover 3 and the components at the bottom of the heat preservation cover 3. The air flow enters from the bottom of the cooking utensil, so that the user cannot see the first air inlet hole 24 and the second air inlet hole 25 in normal use, thereby ensuring the appearance quality of the cooking utensil. In addition, the bottom air intake allows the cold air to contact the bottom of the heat preservation cover 3 first, thereby centrally cooling the bottom of the heat preservation cover 3 and improving the heat dissipation efficiency.

[0071] Specifically, the first air inlet hole 24 and / or the second air inlet hole 25 may extend in the radial direction of the bottom of the housing 1 in a long strip shape, or may extend in a rotating and curved manner. Further, the bending directions of the first air inlet hole 24 and the second air inlet hole 25 may be opposite (i.e., one of them is curved in the counterclockwise direction, and the other is curved in the clockwise direction), or may be the same (i.e., both are curved in the counterclockwise or clockwise direction), which is not limited here.

[0072] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.
