Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a cooking electric cooker. Background Technology

[0002] Currently, most electric hot pots produce a large amount of pungent odors, steam, and unpleasant fumes during use, which greatly affects the dining environment.

[0003] Related technologies typically involve an air duct inside the electric hot pot, within which a fan and filter are installed. The fan draws in cooking fumes from around the pot, which are then filtered and discharged. Oil droplets from the fumes adhere to the filter, eventually affecting its filtration efficiency. Therefore, the filter needs to be disassembled for cleaning or replacement. However, during filter installation and removal, the oil residue on the filter can easily contaminate the user's fingers and even cause other unnecessary contamination to other structures. Utility Model Content

[0004] Therefore, it is necessary to provide a cooking electric cooker that, while satisfying the requirement of oil fume filtration, facilitates the disassembly and assembly of the filter components and reduces user hand contamination and other unnecessary pollution from other structures.

[0005] An electric cooking pot includes a base and a pot body mounted on the base. The base has an air duct with an air inlet and an air outlet. The electric cooking pot also includes a fan and a first filter structure. The fan and the first filter structure are spaced apart in the air duct along the airflow direction. The first filter structure includes a mounting frame and a filter element connected to the mounting frame. The air duct has an air duct wall. The mounting frame is detachably connected to the air duct wall and has a ventilation channel for gas flow.

[0006] Understandably, during cooking, the fumes produced inside the pot are drawn into the duct by the fan. As the air flows towards the outlet, it passes through the first filter structure, where oil droplets adhere to the filter. The filtered air is then discharged from the outlet. The mounting bracket supports the filter, ensuring its stable installation within the duct and reducing the risk of it swaying with the airflow. Because the mounting bracket is detachably connected to the duct wall, the first filter structure can be easily and quickly disassembled and reassembled relative to the base. Furthermore, during disassembly and assembly, direct contact with the filter is unnecessary; only the mounting bracket is required, thus reducing hand contamination and other unnecessary contamination from other components.

[0007] In some embodiments, the base is provided with an assembly notch communicating with the air duct, through which the first filter structure can be inserted into the air duct.

[0008] This design allows for easy assembly and disassembly of the first filter structure via a pull-out mechanism, without the need to disassemble the pot body and base, making operation more convenient.

[0009] In some embodiments, one of the assembly frame and the air duct wall is provided with a snap-fit ​​arm, and the other is provided with a snap-fit ​​part surrounding a snap-fit ​​hole, wherein the snap-fit ​​arm engages with the snap-fit ​​hole and the snap-fit ​​part.

[0010] This design allows for a detachable connection between the assembly frame and the duct wall, improves assembly reliability, and reduces the risk of the first filter structure swaying due to airflow.

[0011] In some embodiments, the end face of the card hole facing the air duct along its own axis is a limiting end face, the card arm has a limiting card protrusion, the card arm passes through the card hole, and the limiting card protrusion abuts against the limiting end face for limiting.

[0012] In other words, by using the inward end face of the card hole as the limiting end face to cooperate with the limiting card protrusion, it is equivalent to increasing the lever arm of the two cooperating and limiting along the insertion direction of the card arm, thereby improving the reliability of the connection.

[0013] In some embodiments, the locking hole includes a limiting section and a guide section connected to the limiting section. The diameter of the limiting section is larger than the diameter of the guide section, and the end face of the guide section facing away from the limiting section serves as the limiting end face. The locking arm includes a force-applying section and a deformation section connected to the force-applying section. The force-applying section and the deformation section are set at an angle. The force-applying section is limited by the limiting section, the deformation section passes through the guide section, and the limiting locking protrudes from the deformation section.

[0014] Understandably, by utilizing the contact engagement between the limiting protrusion and the force application section and the limiting end face and the limiting surface respectively, the upper and lower limits of the first filter structure are achieved, thereby improving the reliability of the connection.

[0015] In some embodiments, the guide segment is gradually extended from the limiting end face toward a direction away from the limiting end face; and / or, there is an assembly gap between the limiting segment and the force-applying segment; and / or, the limiting card is provided with a guide slope.

[0016] Understandably, the gradually widening design causes the guide section's hole wall to be inclined, guiding the snap-fit ​​arm to extend in and ensuring that the deformation section has sufficient deformation space; the assembly gap design makes it easier for the user to apply force to the force application section, thereby disassembling the first filter structure; the guide incline reduces the interference of the limit snap-fit ​​protrusion on the snap-fit ​​arm's insertion hole, facilitating the smooth sliding of the snap-fit ​​arm into the guide section.

[0017] In some embodiments, the assembly frame is provided with an assembly slot, and at least a portion of the filter element is disposed within the assembly slot.

[0018] This design increases the connection area between the filter element and the mounting frame, thereby improving connection reliability and preventing the filter element from easily detaching.

[0019] In some embodiments, the filter element is snap-fitted into the mounting bracket, and / or the filter element is bonded to the mounting bracket.

[0020] Understandably, when using snap-fit, it facilitates the disassembly of the filter element, allowing for separate cleaning of both the filter element and the mounting bracket, and also facilitating direct replacement of the filter element, thus reducing costs. When using adhesive bonding, it effectively improves the connection reliability between the filter element and the mounting bracket, preventing the filter element from falling off during use. When snap-fit ​​and adhesive bonding are used together, the connection reliability is significantly improved.

[0021] In some embodiments, the assembly frame includes an assembly frame and a plurality of support ribs connected to the assembly frame, the plurality of support ribs being spaced apart along the length of the assembly frame to separate a plurality of spaced ventilation channels.

[0022] Understandably, using multiple support ribs can improve the structural strength of the assembly rack and reduce the risk of damage to the assembly rack due to force during assembly and disassembly.

[0023] In some embodiments, the base has extensions protruding on both sides along a first direction, the extensions being located on the outer periphery of the pot body, and each extension having an air outlet.

[0024] This design leaves unvented space around the pot, allowing users to sit comfortably in this space, reducing gas interference and further improving the dining environment.

[0025] In some embodiments, the first filter structure is positioned close to the air outlet.

[0026] In other words, the first filter structure is placed downstream of the fan along the airflow direction to ensure that the gas flowing out of the air outlet is fully filtered by the first filter structure.

[0027] In some embodiments, the air inlet is located in the middle of the base, the middle of the pot body is provided with a through partition, the partition surrounds the outer periphery of the air inlet, the air outlet is located on the outer periphery of the pot body, and the cooking electric cooker further includes a second filter structure, the second filter structure is located at the air inlet of the air duct and is at least partially located within the space surrounded by the partition, and the second filter structure is detachably connected to the base.

[0028] Understandably, the baffle can separate the food from the first filter structure, and the second filter structure works in conjunction with the first filter structure to form a dual filter, which significantly improves the filtration effect. Moreover, because the baffle is located in the middle, it can reduce the size of the second filter structure while ensuring sufficient suction space in the circumference of the pot, thus improving the purification efficiency. The second filter structure is also easy to disassemble and assemble. Attached Figure Description

[0043] Please see Figures 1 to 5 One embodiment of this application provides a cooking electric cooker, including a base 10 and a pot body 20 mounted on the base 10. The base 10 is provided with an air duct 101, which has an air inlet 1011 and an air outlet 1012. The cooking electric cooker also includes a fan 30 and a first filter structure 40, which are spaced apart within the air duct 101 along the airflow direction. The first filter structure 40 includes a mounting frame 41 and a filter element 42 connected to the mounting frame 41. The air duct 101 has an air duct wall, and the mounting frame 41 is detachably connected to the air duct wall and is provided with a ventilation channel 4101 for gas flow.

[0044] It should be noted that the airflow direction is the direction in which the gas flows from the air inlet 1011 to the air outlet 1012 under the action of the fan 30. Figure 3 The direction indicated by the middle arrow is the airflow direction. In actual use, the electric cooker also includes a heating structure 50, which is located at the bottom of the pot body 20.

[0045] When the heating structure 50 is turned on to cook the food in the pot 20, water vapor and oil fumes are generated. At this time, the fan 30 can be turned on to draw the air around the pot 20 into the air duct 101 through the air inlet 1011. As the oil fumes flow towards the air outlet 1012, they pass through the first filter structure 40, and oil droplets can adhere to the filter element 42. The filtered air is then discharged from the air outlet 1012. The mounting bracket 41 can support the filter element 42, ensuring that the filter element 42 is stably mounted in the air duct 101 and reducing the risk of the filter element 42 swaying with the airflow. In addition, the ventilation channel 4101 on the mounting bracket 41 reduces the obstruction to the airflow and ensures normal gas flow. Because the mounting bracket 41 is detachably connected to the duct wall, the first filter structure 40 can be assembled and disassembled as a whole relative to the base 10. Especially during assembly, this not only reduces assembly errors but also ensures the assembly accuracy of the filter element 42, avoiding filtration dead zones caused by the misalignment of the filter element 42. Furthermore, during assembly and disassembly, there is no need to directly contact the filter element 42; only the mounting bracket 41 needs to be in contact, reducing user hand contamination and unnecessary contamination from other structures, and improving the protection of the filter element 42. At the same time, due to the detachable connection between the mounting bracket 41 and the duct wall, if the filter element 42 is a reusable component, it facilitates the cleaning of the first filter structure 40, eliminating the risk of cleaning fluid flowing into other structures inside the base 10 during the cleaning process; if the filter element 42 is made of cotton material, it is easy to replace.

[0046] In some embodiments, the first filter structure 40 can be located near the air outlet 1012, that is, downstream of the fan 30 along the airflow direction, to ensure that the gas flowing out of the air outlet 1012 is fully filtered by the first filter structure 40. Of course, the first filter structure 40 can also be located near the air inlet 1011, that is, upstream of the fan 30 along the airflow direction, to ensure that the flue gas flowing to the fan 30 has been filtered, reducing the pollution of the fan 30 by the flue gas.

[0047] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments, the base 10 is provided with an assembly notch 102 for connecting the ventilation duct 101, and the first filter structure 40 can be inserted into the ventilation duct 101 through the assembly notch 102. That is to say, by using the assembly notch 102, the first filter structure 40 can be easily disassembled and assembled by pulling, without disassembling the pot body 20 and the base 10, making the operation more convenient; moreover, the assembly notch 102 can also limit the position of the first filter structure 40, improving the assembly reliability of the first filter structure 40.

[0048] In some specific embodiments, the base 10 includes an upper shell 11 and a lower shell 12 connected to each other. The two shells are fastened together to form an air duct 101. Therefore, the inner walls of the upper shell 11 and the lower shell 12 forming the air duct 101 both serve as air duct walls. The bottom of the lower shell 12 is provided with an assembly notch 102 to facilitate the assembly and disassembly of the first filter structure 40 from the bottom of the cooking rice cooker. Of course, the assembly notch 102 may be provided on the side wall of the lower shell 12 or the side wall of the upper shell 11, or both the side walls of the upper shell 11 and the lower shell 12 may be provided with communicating assembly notches 102, as long as it facilitates the assembly of the first filter structure 40 by pulling it out.

[0049] A seal may be provided between the first filter structure 40 and the side wall of the assembly notch 102 to ensure airtightness during installation and reduce oil fume leakage. Specifically, when the first filter structure 40 is inserted into the air duct 101 through the assembly notch 102, the edge of the assembly frame passes through the assembly notch 102, and a seal is provided between the two. This is only an example.

[0050] In actual use, the upper shell 11 is also provided with a heat insulation plate 13 on the side opposite to the lower shell 12, and the pot body 20 with the heating structure 50 welded on it is supported by the heat insulation plate 13.

[0051] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments, one of the assembly frame 41 and the duct wall is provided with a snap-fit ​​arm 61, and the other is provided with a snap-fit ​​part 62 forming a snap-fit ​​hole 621. The snap-fit ​​arm 61 engages with the snap-fit ​​part 62 through the snap-fit ​​hole 621. This arrangement allows for the detachable connection of the assembly frame 41 relative to the duct wall; moreover, the snap-fit ​​engagement improves assembly reliability, ensuring that the first filter structure 40 is securely installed in the duct 101 without significant external force, reducing the risk of the first filter structure 40 shaking due to excessive airflow velocity.

[0052] In some specific embodiments, the assembly notch 102 is located at the bottom of the lower shell 12, the snap-fit ​​part 62 is located on the lower shell 12, and the snap-fit ​​hole 621 communicates with the assembly notch 102. The snap-fit ​​arm 61 is located at the bottom of the assembly frame 41. As the first filter structure 40 is inserted through the assembly notch 102, the snap-fit ​​arm 61 and the snap-fit ​​hole 621 are engaged and positioned. The top of the assembly frame 41 abuts against the upper shell 11 and may be provided with a sealing element to ensure the sealing of the abutment, so that the oil fumes flowing into the air duct 101 can flow fully to the filter element 42. The snap-fit ​​part 62 is integrally formed with the lower shell 12, and the snap-fit ​​arm 61 is integrally formed with the assembly frame 41.

[0053] Alternatively, the snap-fit ​​part 62 can be provided on the upper shell 11, the snap-fit ​​arm 61 can be provided on the top of the assembly frame 41, and the bottom of the assembly frame 41 can abut against the lower shell 12. Alternatively, both the upper shell 11 and the lower shell 12 can have snap-fit ​​parts 62, and the top and bottom of the assembly frame 41 can also have snap-fit ​​arms 61. Or, the snap-fit ​​part 62 can be provided on the assembly frame 41, and the snap-fit ​​arm 61 can be provided on either the upper shell 11 or the lower shell 12. This is merely an example.

[0054] In some specific embodiments, multiple snap-fit ​​arms 61 are provided and arranged at intervals along the length of the assembly frame 41. Each snap-fit ​​arm 61 corresponds to a snap-fit ​​part 62 to improve assembly reliability.

[0055] In other embodiments, the mounting bracket 41 can also be connected to the duct wall by screws to allow for detachment.

[0056] Please see Figure 1 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the end face of the locking hole 621 facing the air duct 101 along its own axial direction is a limiting end face 6213. The locking arm 61 has a limiting locking protrusion 613 protruding from it. The locking arm 61 passes through the locking hole 621, and the limiting locking protrusion 613 abuts against the limiting end face 6213 for limiting. Taking the first filter structure 40 being inserted into the assembly notch 102 from bottom to top as an example, the locking part 62 protrudes from the inner wall of the lower shell 12. The axial direction of the locking hole 621 is vertical and passes through the locking part 62 along its own axial direction. The limiting end face 6213 is located at the protruding end of the locking part 62 facing the air duct 101. In this way, not only is it prevented from the first filter structure 40 from detaching from the assembly notch 102, but the distance between the limiting locking protrusion 613 and the assembly notch 102 is also increased, which is equivalent to increasing the lever arm and making the connection more reliable.

[0057] Alternatively, the wall of the card hole 621 may have a card groove recessed radially outward, with the limiting card protrusion 613 extending into the card groove for limiting.

[0058] like Figures 4 to 6 As shown, in some embodiments, the locking hole 621 includes a limiting section 6211 and a guide section 6212 connected to the limiting section 6211. The diameter of the limiting section 6211 is larger than the diameter of the guide section 6212. The end face of the guide section 6212 facing away from the limiting section 6211 serves as a limiting end face 6213. The locking arm 61 includes a force-applying section 611 and a deformation section 612 connected to the force-applying section 611. The deformation section 612 and the force-applying section 611 are arranged at an angle. The force-applying section 611 is limited by the limiting section 6211, the deformation section 612 is accommodated in the guide section 6212, and the limiting locking protrusion 613 protrudes from the deformation section 612.

[0059] The limiting segment 6211 is located below the guiding segment 6212, and because the diameter of the limiting segment 6211 is larger than that of the guiding segment 6212, a limiting surface 6214 is provided between the limiting segment 6211 and the guiding segment 6212. Therefore, when the latching arm 61 is inserted from bottom to top, the limiting latch protrusion 613 is squeezed by the hole wall of the guiding segment 6212, causing the deformation segment 612 to deform until the limiting latch protrusion 613 moves to the end of the guiding segment 6212 away from the limiting segment 6211 and loses its squeezing effect. The deformation segment 612 then recovers and the limiting latch protrusion 613 is limited to the limiting end face 6213. In addition, the force-applying segment 611 can abut against the limiting surface 6214 to limit the insertion depth of the latching arm 61. Thus, by utilizing the contact engagement between the limiting protrusion 613 and the force application section 611 and the limiting end face 6213 and the limiting surface 6214 respectively, the upper and lower limits of the first filter structure 40 are achieved, thereby improving the reliability of the connection.

[0060] Specifically, the deformation section 612 includes an inclined section and an L-shaped section. The horizontal part of the L-shaped section is connected to the assembly frame 41, and the vertical part is connected to the inclined section. This arrangement can reduce the component forces in other directions, further improve the structural strength of the snap-fit ​​arm 61, and extend its service life.

[0061] like Figure 5 As shown, furthermore, the guide section 6212 gradually expands from the limiting end face 6213 toward the direction away from the limiting end face 6213. Specifically, the guide section 6212 gradually expands from top to bottom in the vertical direction. This arrangement facilitates the insertion of the guide latch arm 61 into the latch hole 621 and adapts to the inclined deformation section 612, ensuring that the deformation section 612 has a certain amount of room to move. The limiting latch protrusion 613 is provided with a guide slope 6131, the inclination direction of which is the same as that of the guide section 6212, which facilitates the smooth sliding of the guide latch arm 61 into the guide section 6212. At the same time, there is an assembly gap between the hole wall of the limiting section 6211 and the force application section 611, which allows the user to apply force to the force application section 611 from the assembly gap to deform the latch arm 61 and release the latch, thus satisfying the disassembly of the first filter structure 40.

[0062] Please see Figures 4 to 6 In some embodiments, the assembly frame 41 is provided with an assembly groove 4102, and at least a portion of the filter element 42 is disposed in the assembly groove 4102. That is, the assembly frame 41 is recessed along its own thickness direction to form the assembly groove 4102, so as to constrain the filter element 42 around its perimeter through the assembly groove 4102, which not only increases the connection area with the filter element 42, but also improves the connection reliability and prevents the filter element 42 from easily detaching.

[0063] Furthermore, the assembly frame 41 includes an assembly frame 411 and multiple support ribs 412 connected to the assembly frame 411. The multiple support ribs 412 are spaced apart along the length of the assembly frame 411 to create multiple spaced ventilation channels 4101. Specifically, the length of the assembly frame 411 is angled to the airflow direction, specifically vertically, to ensure that the filter element 42 can face the airflow directly and effectively filter the air. The assembly frame 411 is a rectangular frame, and the arrangement of the multiple support ribs 412 increases the structural strength of the assembly frame 41 itself. The multiple support ribs 412 can support the filter element 42, preventing it from deforming due to airflow. The aforementioned snap-fit ​​arm 61 can be connected to one of the support ribs 412. The dimension of the support rib 412 along the thickness direction of the assembly frame 411 is smaller than the dimension of the assembly frame 411, thus forming the aforementioned assembly groove 4102, which facilitates the installation of the filter element 42. The width of the support rib 412 located in the middle can be slightly larger than that of the other support ribs 412, and the aforementioned snap-fit ​​arm 61 can be connected to the support rib 412 located in the middle, thereby ensuring structural strength and uniform stress distribution.

[0064] Furthermore, the filter element 42 can be snapped into the mounting bracket 41. For example, the side wall of the filter element 42 has a snap-fit ​​protrusion, and the groove wall of the mounting slot 4102 has a snap-fit ​​groove, with the snap-fit ​​protrusion snapping into the groove. Alternatively, the snap-fit ​​protrusion can be located on the groove wall of the mounting slot 4102, and the snap-fit ​​hole 621 can be located on the side wall of the filter element 42. The snap-fit ​​protrusion can be hemispherical, with the snap-fit ​​groove fitting accordingly. The key is to ensure the reliable connection between the filter element 42 and the mounting bracket 41.

[0065] In other words, the snap-fit ​​design facilitates the disassembly of the filter element 42, allowing for separate cleaning of both the filter element 42 and the mounting bracket 41, and enabling direct replacement of the filter element 42 without replacing the entire first filter structure 40, thus reducing costs. Alternatively, the filter element 42 can also be fixed to the mounting bracket 41 with screws.

[0066] Alternatively, the filter element 42 can be bonded to the mounting frame 41. That is, adhesive can be applied evenly to the aforementioned multiple support ribs 412, and then the filter element 42 can be pressed into the mounting groove 4102 to achieve bonding and fixation. This bonding and fixing method effectively improves the connection reliability between the filter element 42 and the mounting frame 41, preventing the filter element 42 from falling off during use.

[0067] Another replaceable filter element 42 is snapped into and bonded to the mounting frame 41, which significantly improves the reliability of the connection.

[0068] In some embodiments, the filter element 42 may be made of fiber cotton with a fine pore structure. Alternatively, the filter element 42 may be a negative ion generator, in which case a positive ion plate is also provided in the air duct 101. The negative ions generated by the negative ion generator diffuse into the air duct 101 and combine with the gas, and move towards the positive ion plate under the action of the electric field force, thereby causing the flue gas particles to be deposited on the positive ion plate, thus achieving filtration.

[0069] Please see Figure 1 , Figure 2 , Figure 3 and Figure 7 In some embodiments, the base 10 has extensions 103 protruding on both sides along a first direction. The extensions 103 are located on the outer periphery of the pot body 20, and each extension 103 has an air outlet 1012. The first direction is... Figure 7 The left and right directions are reserved in this way, which ensures that there is space for steam to escape in the front and back directions of the pot body 20, making it easier for users to sit in the front and back directions of the pot body 20, reducing gas interference and further improving the dining environment.

[0070] like Figures 1 to 4 As shown, specifically, each of the two extensions 103 has a first filter structure 40 installed on its opposite side, dividing the air duct 101 into a central region and two side regions. The flue gas flowing into the central region from the air inlet 1011 needs to pass through the first filter structure 40 to the side regions, and then be discharged from the air outlet 1012. The upper shell 11, on the side opposite to the lower shell 12, has multiple spaced, elongated second ventilation holes 1101, which together define the air outlet 1012. This arrangement, while allowing for air discharge, prevents food items from falling into the air duct 101; furthermore, this arrangement allows for upward exhaust, facilitating the re-extraction and filtration of the discharged gas, thus improving the filtration effect.

[0071] Alternatively, an annular air outlet 1012 may be provided on the outer periphery of the pot body 20.

[0072] Please see Figure 1 , Figure 2 , Figure 3 and Figure 7In some embodiments, the air inlet 1011 is located in the middle of the base 10, and the pot body 20 has a through partition 21 in the middle, which surrounds the outer periphery of the air inlet 1011. The air outlet 1012 is located on the outer periphery of the pot body 20. The cooking electric cooker also includes a second filter structure 80, which is located at the air inlet 1011 of the air duct 101 and is at least partially located within the space surrounded by the partition 21. The second filter structure 80 is detachably connected to the base 10. It can be understood that the partition 21 separates the food from the first filter structure 40, preventing the food from dripping into the air duct 101 when boiling and affecting the second filter structure 80 and the fan 30. Moreover, this arrangement, while reducing the size of the second filter structure 80, ensures sufficient suction space around the pot body 20, improving purification efficiency. The second filter structure 80 is used to filter the oil fumes at the air inlet 1011, and the first filter structure 40 is used to filter the oil fumes flowing towards the air outlet 1012, thus forming a dual filtration system and improving the oil fume purification effect. During use, after removing the pot body 20, the second filter structure 80 can be completely exposed, making it easy to disassemble the second filter structure 80 relative to the base 10.

[0073] The second filter structure 80 includes a protective cover 81 surrounding a cylindrical cavity 8101 and a filter screen 82 disposed within the cylindrical cavity 8101 and connected to the protective cover 81. The cylindrical cavity 8101 is connected to the air inlet 1011 of the air duct 101. A portion of the protective cover 81 protrudes from the partition 21 and has multiple spaced first ventilation holes 8102 at the protrusion, facilitating the direct flow of oil fumes into the cylindrical cavity 8101 and their filtration by the filter screen 82. The protective cover 81 is detachably connected to the base 10, for example, by means of screws or clips; alternatively, the base 10 has a positioning groove, into which the bottom of the protective cover 81 is inserted for positioning. The partition 21 of the pot body 20 limits the radial movement of the second filter structure 80. The top of the partition 21 has a limiting flange that abuts against the protective cover 81 to limit the displacement of the second filter structure 80 along the axial direction (i.e., vertical direction) of the pot body 20.

[0074] Furthermore, the cooking rice cooker also includes a support base 70, which is disposed on the base 10 and serves to support the second filter structure 80, so that the top of the protective cover 81 protrudes beyond the top of the partition 21. The support base 70 includes a support portion 71 and a reinforcing portion 72 connected to the support portion 71. The support portion 71 is supported on the base 10 and surrounds the outer periphery of the reinforcing portion 72. The bottom of the protective cover 81 is placed on the support portion 71. The reinforcing portion 72 increases the structural strength of the support base 70 and improves the support stability; and the arrangement of multiple through holes 7201 on the reinforcing portion 72 facilitates gas flow.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
