Description

Technical Field

[0001] The present specification relates to the technical field of small household appliances, and in particular to a grinding assembly and a food processor. Background Art

[0002] Most existing food processors heat the food through a heating plate at the bottom, and then crush the food through a knife assembly. The knife assembly crushes the food by stirring the turbulent flow to make the food hit the blade and chop the food, which makes the food not delicate enough and has a poor taste.

[0003] In order to solve this problem, some products (such as original grinding soymilk machines) replace the crushing blade with a grinding component, which squeezes and grinds the ingredients to improve the taste. However, the grinding component has a low rotation speed, and when cooking some sticky ingredients (such as rice), the ingredients stick to the bottom seriously and are prone to scorching. Utility Model Content

[0004] The purpose of the present application is to provide a grinding component and a food processor, wherein the grinding component can improve the taste of food and avoid the problem of food burnt due to the low rotation speed of the grinding head component.

[0005] The present application discloses a grinding assembly, which includes a heating plate and a grinding head assembly. The heating plate includes a plate body and a heating element, the plate body includes a plate bottom and a plate side wall surrounding the plate bottom, and the heating element is arranged on the plate side wall. The grinding head assembly is assembled on the plate bottom, and includes an inner grinding head and an outer grinding head, the inner grinding head is inserted into the outer grinding head, and the inner grinding head and the outer grinding head rotate relative to each other. The grinding assembly includes a feed inlet and a discharge port, and the heating element is located between the feed inlet and the discharge port.

[0006] As in the above arrangement, the inner grinding head and the outer grinding head rotate relative to each other to achieve a crushing effect, so that the food materials are crushed by grinding and extrusion, and the food materials are more delicate and have a better taste. In addition, because the heating element is arranged on the side wall of the plate, and the heating element is located between the feed port and the discharge port, after the heating element heats the side wall of the plate, the heat is transferred to the bottom of the plate through the side wall of the plate, and then the food on the bottom of the plate is heated, avoiding direct heating of the bottom of the plate, and making the food materials heated more evenly. Therefore, the above arrangement can also avoid the phenomenon of the bottom of the plate being burnt due to the low rotation speed of the grinding head assembly.

[0007] Furthermore, the grinding assembly includes a temperature measuring assembly arranged on the disc body, and the temperature measuring portion of the temperature measuring assembly protrudes from the bottom of the disc. A feed port is arranged at the bottom end of the grinding head assembly. Along the circumference of the outer grinding head, the angle of the temperature measuring portion of the temperature measuring assembly deviating from the feed port is a, 30°≤a≤330°.

[0008] As set above, 30°≤a≤330° can make the temperature measuring component (especially the temperature measuring part) avoid the feed port, so as to prevent the temperature measuring part of the temperature measuring component from affecting the feeding effect of the feed port.

[0009] Further, a feed port is provided at the bottom end of the grinding head assembly, and along the axial direction of the grinding head assembly, the height of the heating element at least partially overlaps with the height of the feed port. Alternatively, a discharge port is provided at the bottom end of the grinding head assembly, and along the axial direction of the grinding head assembly, the height of the heating element at least partially overlaps with the height of the discharge port.

[0010] As described above, since the height of the heating element at least partially overlaps with the height of the feed port, the heating element is located within the surface area of ​​the feed port, and the effect of feeding the feed port to drive the flow of food (such as siphon effect) can increase the flow rate of food on the inner surface of the side wall of the plate corresponding to the heating element, sucking away the food and cleaning the food on the side wall of the plate, thereby reducing the amount of food adhering to the inner surface of the side wall of the plate and preventing the side wall of the plate from being burned. The height of the heating element at least partially overlaps with the height of the discharge port, and the food is usually sprayed out from the discharge port after being ground, which is also conducive to increasing the flow rate on the inner surface of the side wall of the plate corresponding to the heating element, thereby cleaning the food on the side wall of the plate and preventing the side wall of the plate from being burned.

[0011] Furthermore, along the axial direction of the grinding head assembly, the height of the feed port relative to the bottom of the disc is L, the height of the heating element relative to the bottom of the disc is P, and P≤L.

[0012] As set up above, since P≤L, the effect of the food flow caused by the feeding through the feed port (such as siphon effect) can better absorb the food on the inner surface of the side wall of the dish corresponding to the heating element, clean up the food on the side wall of the dish, and thus reduce the amount of food adhering to the inner surface of the side wall of the dish, avoiding the side wall of the dish from being burned.

[0013] Further, the grinding assembly comprises a knife assembly and a rotating shaft, wherein the rotating shaft is connected to the inner grinding head or the outer grinding head. The knife assembly is connected to the rotating shaft and is spaced apart from the grinding head assembly in the axial direction of the rotating shaft.

[0014] As set up above, since the rotating shaft is connected to the knife assembly, the rotating shaft and the inner grinding head or the outer grinding head, when the inner grinding head or the outer grinding head rotates, the corresponding inner grinding head or the outer grinding head will drive the knife assembly to rotate synchronously, so that the rotation of the knife assembly can generate turbulence, and the turbulence can promote the movement of food in the cavity surrounded by the bottom and the side walls of the plate (the cavity of the heating plate), improve the fluidity of the food, and thereby prevent the food from sticking to the bottom and / or the side walls of the plate, and prevent the bottom and / or the side walls of the plate from being burned.

[0015] Furthermore, the grinding head assembly includes a feed port; along the axial direction of the grinding head assembly, the distance from the top of the feed port to the bottom of the disc is L; the distance from the knife assembly to the bottom of the disc is H; 10mm≤HL≤50mm.

[0016] As set above, 10mm≤HL≤50mm ensures that the knife assembly is lower than the bottom of the plate, so that the knife assembly is closer to the area where food is easy to stick. The turbulence generated by the rotation of the knife assembly improves the turbulence effect in the area where food is easy to stick, thereby increasing the possibility of debonding of stuck food, reducing food sticking, and avoiding sticking to the bottom and / or burning of the side walls of the plate.

[0017] Furthermore, the heating element is arranged around the disk side wall so that the disk side wall has a cold end area, and the grinding component includes a temperature measuring component, which is arranged on the bottom of the disk or the disk side wall and corresponds to the cold end area.

[0018] As set above, the temperature of the cold end area is lower than the temperature of other places on the side wall of the disk. The temperature measuring component corresponds to the cold end area. Therefore, the temperature measured by the temperature measuring component can better reflect the actual temperature of the heating disk, ensuring accurate temperature measurement.

[0019] Furthermore, along the radial direction of the disc bottom, the distance between the temperature measuring component and the outer grinding head is D2, the maximum distance between the outer grinding head and the side wall of the disc is D1, and 2mm≤D1-D2≤25mm.

[0020] As set above, since 2mm≤D1-D2≤25mm, when the temperature measuring component needs to be assembled on the side wall of the disk, there is enough area on the side wall of the disk to install the temperature measuring component; when the temperature measuring component needs to be set on the bottom of the disk, the distance ensures that the temperature measuring component will not be too close to the external grinding head, thereby ensuring the feeding efficiency of the feed port, because being too close to the external grinding head will affect the feeding efficiency of the feed port.

[0021] Further, the disk sidewall is a curved surface, and / or the cavity enclosed by the disk sidewall and the disk bottom gradually increases in a direction away from the disk bottom.

[0022] As set up as above, since the side wall of the dish is a curved wall, compared with a flat plate-shaped side wall, the contact area between the heating element and the side wall of the dish can be increased, so that the food can be better heated by the heating element, and the heating efficiency and energy utilization rate can be improved. Moreover, the contact area is relatively large, which can also avoid the side wall of the dish from being burned due to heat concentration. In addition, the side wall of the dish is a curved wall, which can make the space enclosed by the side wall of the dish and the bottom of the dish smaller (for example, the height of the heating dish is reduced to make the enclosed space smaller). In the case where the grinding assembly includes a knife assembly, the small space can make the turbulence effect better, and further avoid the food sticking to the bottom of the dish and / or the side wall of the dish. Since the cavity gradually increases in the direction away from the bottom of the dish, it ensures that the space is small and the turbulence effect is good, and further avoids the food sticking to the bottom of the dish and / or the side wall of the dish.

[0023] Another aspect of the present application provides a food processor, the food processor comprising a main unit, a mixing cup and any one of the aforementioned grinding components. The disk is disposed at the bottom of the mixing cup, the main unit comprises a driving device and a control panel, the control panel controls the driving device to drive one of the inner grinding head and the outer grinding head to rotate relative to the other, and controls the heating element to heat.

[0024] As configured above, the food processor at least has the beneficial effects of the grinding component.

[0025] In some embodiments, the food processor includes a cup holder and a bottom cover, the heating plate is fixed between the cup holder and the bottom cover, the bottom cover is assembled with the cup holder and includes a accommodating cavity; the plate bottom includes a mounting hole passing through the plate bottom; the outer grinding head includes a mounting section, the inner grinding head is fixed to a rotating shaft, the rotating shaft is rotatably connected to a bearing assembly inside the mounting section, and the mounting section passes through the mounting hole; the food processor also includes a fixing ring and a sealing member fixed to the fixing ring; the fixing ring and the sealing member are both located in the accommodating cavity, and are connected to the mounting section by threads or snaps so that the outer grinding head is pressed against the plate bottom; the sealing member is in sealing contact with the cavity wall of the accommodating cavity.

[0026] As set up above, the threaded connection or snap connection is achieved by rotating the fixing ring, and then the outer grinding head (or the assembly consisting of the outer grinding head and the inner grinding head) is assembled or disassembled from the heating plate, thereby facilitating the assembly and disassembly of the outer grinding head (or the assembly consisting of the outer grinding head and the inner grinding head).

[0035] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this specification.

[0036] The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this specification. The singular forms "a", "the" and "the" used in this specification and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0037] Next, the embodiments of this specification are described in detail.

[0038] See also Figure 3 , Figure 5 and Figure 6 Combined with Figure 1 and Figure 2The present application discloses a grinding assembly 21, which includes a heating plate 213 and a grinding head assembly. The grinding head assembly includes an outer grinding head 212 and an inner grinding head 211. The heating plate 213 includes a plate body 2133 and a heating element 2131, and the plate body 2133 includes a plate bottom 21331 and a plate side wall 21332 surrounding the plate bottom 21331. In this way, the plate body 2133 includes a cavity 2134. The structures of the plate bottom 21331 and the plate side wall 21332 are not limited to the structures described below. See Figure 5 and Figure 6 Combined with Figure 3 , the heating element 2131 is arranged on the side wall 21332 of the disk. In an embodiment of the present application, the outer grinding head 212 is assembled on the bottom 21331 of the disk. The outer grinding head 212 is provided with a feed port 2121, and the feed port 2121 is located at the bottom end of the grinding head assembly. The inner grinding head 211 is located inside the outer grinding head 212, and forms a grinding channel 210 with the outer grinding head 212, and the grinding channel 210 connects the feed port 2121 and the outside of the grinding assembly 21. Technicians can understand that the inner wall of the outer grinding head 212 is provided with external grinding teeth, and the inner grinding head 211 is provided with internal grinding teeth. In the above arrangement, the inner grinding head 211 rotates while the outer grinding head 212 is stationary. In other embodiments, the inner grinding head 211 may be stationary while the outer grinding head 212 rotates. In the above embodiment, the feed port 2121 is located at the bottom end of the grinding head assembly, so that the grinding head assembly feeds (ingredients) at the bottom end, and the ingredients are discharged from the top end after being ground. As a variation of this embodiment, the feed port 2121 may also be located at the top end of the grinding head assembly, and the discharge port may be located at the bottom end of the grinding head assembly. For the various embodiments of the present application, the respective structures of the feed port and the discharge port are not limited, as long as feeding and discharging can be achieved. The grinding assembly includes a feed port and a discharge port, and the heating element is located between the feed port and the discharge port.

[0039] As described above, the inner grinding head 211 and the outer grinding head 212 rotate relative to each other, so that the outer grinding teeth of the outer grinding head and the inner grinding teeth of the inner grinding head rotate relative to each other, which plays a crushing role. The food is crushed by grinding and extrusion (that is, the large pieces of food are finally turned into particles), which can obtain a better taste. In addition, the heating element 2131 is arranged on the side wall 21332 of the plate, and the heating element is located between the feed port and the discharge port. After the heating element 2131 heats the side wall 21332 of the plate, the heat is transferred to the bottom 21331 of the plate through the side wall 21332 of the plate, and then the food on the bottom 21331 of the plate is heated, avoiding direct heating of the bottom 21331 of the plate, so that the food can be heated more evenly. Therefore, the above-mentioned setting can avoid the phenomenon of the bottom 21331 of the plate being burnt due to the low rotation speed of the grinding head assembly.

[0040] In some embodiments, Figure 4As shown, the grinding assembly 21 includes a temperature measuring assembly 2132 arranged on the disc body 2133, and the temperature measuring portion 21321 of the temperature measuring assembly 2132 protrudes from the disc bottom 21331. A feed port 2121 is arranged at the bottom end of the grinding head assembly. Along the circumference of the outer grinding head 212, the angle at which the temperature measuring assembly 2132 deviates from the feed port 2121 is a, and a=90 degrees. However, based on the role of a described later, the technicians can understand that 30°≤a≤330°, for example, 30°, 35°, 38°, 45°, 48°, 50°, 55°, 58°, 65°, 70°, 75°, 78°, 80°, 85°, 90°, 93°, 95°, 98°, 105°, 110°, 115°, 118°, 120°, 123°, 130°, 135°, 138°, 140°, 143°, 145°, 148°, 150°, 155°, 160°, 170°, 180°, 190°, 200°, 210°, 220°, 230°, 240°, 250°, 260°, 270°, 280°, 290°, 300°, 310°, 320° or 330°.

[0041] As set above, 30°≤a≤330° can make the temperature measuring component 2132 (especially the temperature measuring part) avoid the feed inlet 2121, so as to prevent the temperature measuring part 21321 of the temperature measuring component from affecting the feed effect (such as siphon effect) of the feed inlet. Because the temperature measuring part 21321 protrudes from the bottom 21331 of the dish, if the temperature measuring part 21321 is too close to the feed inlet 2121, it will block the food from entering the feed inlet and reduce the feed efficiency, thus affecting the working efficiency of the food processor.

[0042] In some embodiments, Figure 5 , Figure 6 and Figure 7 As shown, the bottom end of the grinding head assembly is provided with a feed port 2121. Along the axial direction of the grinding head assembly, the height of the heating element 2131 at least partially overlaps with the height of the feed port 2121. Figure 6 The P and L at least partially overlap. The heating element is located between the feed port and the discharge port by at least partially overlapping. Figure 6 Complete overlap is shown in the figure, but technicians can understand based on subsequent effects that it can also be partial overlap as long as the described effect can be achieved.

[0043] As set up as above, since the height of the heating element 2131 at least partially overlaps with the height of the feed port 2121, the heating element 2131 is located within the surface area of ​​the feed port 2121. The feed port 2121 drives the flow of food (such as siphon effect) to increase the flow rate of food on the inner surface of the dish side wall 21332 corresponding to the heating element 2131, suck the food away, clean up the food on the dish side wall 21332, and thereby reduce the amount of food adhering to the inner surface of the dish side wall, avoiding the dish side wall 21332 from being burned.

[0044] In some other embodiments, a discharge port is provided at the bottom end of the grinding head assembly; along the axial direction of the grinding head assembly, the height of the heating element 2131 at least partially overlaps with the height of the discharge port. In this way, the heating element is located between the feed port and the discharge port by at least partially overlapping.

[0045] As set up above, when the height of the heating element and the height of the discharge port at least partially overlap, the food is usually sprayed out from the discharge port after being ground, which is also beneficial to increase the flow rate on the inner surface of the side wall of the dish corresponding to the heating element, and then clean up the food on the side wall of the dish to avoid burning the side wall of the dish.

[0046] In some embodiments, Figure 5 , Figure 6 and Figure 7 As shown, along the axial direction of the grinding head assembly, the height of the feed port 2121 relative to the disc bottom 21331 is L, and the height of the heating element 2131 relative to the disc bottom 21331 is P, P≤L. The further size range is 5mm≤P≤L≤55mm, and the preferred selection range is 10-25mm.

[0047] As set up above, since P≤L, the effect of the flow of food caused by the feeding at the feed port 2121 (such as siphon effect) can better suck away the food on the inner surface of the dish side wall 21332 corresponding to the heating element 2131, clean up the food on the dish side wall 21332, and thereby reduce the amount of food adhering to the inner surface of the dish side wall 21332, avoiding the dish side wall 21332 from being burned.

[0048] like Figure 3 and Figure 6 Combined with Figure 4 and Figure 5As shown, the grinding assembly 21 includes a knife assembly 2161 and a rotating shaft 2162. The knife assembly 2161 in the embodiment of the present application includes a blade and related components for fixing and assembling the blade and the rotating shaft 2162. The rotating shaft 2162 is connected to the inner grinding head 211, and there is no limit on how to link, as long as the inner grinding head 211 can be rotated as described later. When the rotating shaft 2162 is driven, the inner grinding head 211 and the knife assembly 2161 rotate synchronously. The rotating shaft 2162 drives the inner grinding head 211 to rotate. For example, the inner grinding head 211 includes a through hole, and the rotating shaft 2162 is arranged through the through hole. The cross section of the through hole and the cross section of the corresponding section of the rotating shaft 2162 are both polygonal, and the polygonal flat structure is formed after being interlaced, so that the inner grinding head 211 can be driven to rotate. Of course, when the outer grinding head rotates and the inner grinding head is stationary, the rotating shaft 2162 is connected to the outer grinding head, and then, the rotation of the rotating shaft 2162 drives the outer grinding head to rotate.

[0049] As set up above, since the rotating shaft 2162 is connected to the knife assembly 2161, the rotating shaft 2162 and the inner grinding head or the outer grinding head, when the inner grinding head or the outer grinding head rotates, the corresponding inner grinding head or the outer grinding head will drive the knife assembly to rotate synchronously, so that the rotation of the knife assembly 2161 can generate turbulence, and the turbulence can promote the movement of the food in the cavity surrounded by the bottom and the side walls of the plate (the cavity of the heating plate), improve the fluidity of the food, and thereby prevent the food from sticking to the bottom and / or the side walls of the plate, and prevent the bottom and / or the side walls of the plate from being burned. For example, when the food processor cooks some sticky food (such as rice), it can prevent the food from sticking to the bottom and / or the side walls, causing the bottom and / or the side walls of the plate to be burned.

[0050] like Figure 6 As shown, the grinding head assembly includes a feed port 2121; along the axial direction of the outer grinding head 212, the distance between the top of the feed port 2121 and the bottom 21331 of the disc is L; the distance between the knife assembly 2161 and the bottom 21331 is H; 10mm≤HL≤50mm, for example, 10mm, 15mm, 18mm, 20mm, 25mm, 28mm, 30mm, 33mm, 35mm, 38mm, 40mm, 43mm, 45mm, 48mm or 50mm.

[0051] As set above, 10mm≤HL≤50mm ensures that the knife assembly 2161 is lower than the bottom of the plate 21331, so that the knife assembly 2161 is closer to the area where the food is easy to stick. The turbulence generated by the rotation of the knife assembly 2161 improves the turbulence effect in the area where the food is easy to stick, thereby increasing the possibility of debonding of the stuck food, reducing the adhesion of the food and avoiding sticking to the bottom.

[0052] like Figure 3 Combined with Figure 4 and Figure 6As shown, the heating element 2131 is arranged around the disk side wall 21332 so that the disk side wall 21332 has a cold end area 21333. For example, when the heating element 2131 is a heating tube, the heating tube includes two terminals 21334, and the area between the other terminals 21334 on the disk side wall 21332 is the cold end area. The grinding assembly 21 includes a temperature measuring assembly 2132, which is arranged on the disk bottom 21331 or the disk side wall 21332 and corresponds to the cold end area 21333.

[0053] As set above, the temperature of the cold end area 21333 is lower than the temperature of other places on the disk side wall 21332, and the temperature measuring component 2132 corresponds to the cold end area 21333. Therefore, the temperature measured by the temperature measuring component 2132 can better reflect the actual temperature of the heating disk 213, ensuring accurate temperature measurement.

[0054] like Figure 6 As shown, along the radial direction of the disk bottom 21331, the distance between the temperature measuring component 2132 and the outer grinding head 212 is D2. Figure 6 Although the temperature measuring component 2132 is not shown in the figure, the mounting hole 21320 for mounting the temperature measuring component 2132 is shown. Therefore, the mounting hole 21320 can be used as a reference. The maximum distance between the outer grinding head 212 and the disc side wall 21332 is D1, 2mm≤D1-D2≤25mm. In the present application, the disc side wall 21332 is a curved surface, so it is the maximum distance.

[0055] As set above, since 2mm≤D1-D2≤25mm, when the temperature measuring component 2132 needs to be assembled on the disk side wall 21332, there is enough area on the disk side wall 21332 to install the temperature measuring component 2132; when the temperature measuring component 2132 needs to be set on the disk bottom 21331, the distance ensures that the temperature measuring component 2132 will not be too close to the outer grinding head 212, thereby ensuring the feeding efficiency of the feed port 2121, because being too close to the outer grinding head 212 will affect the feeding efficiency of the feed port.

[0056] like Figure 6 As shown, the disk side wall 21332 is a curved wall. However, based on subsequent effects, as long as the disk side wall 21332 is a curved wall, the curved wall can also be a wavy curved surface, etc.

[0057] As described above, since the side wall 21332 of the plate is a curved wall, compared with the side wall 21332 of the plate being flat, the contact area between the heating element 2131 and the side wall 21332 of the plate can be increased, so that the food can be better heated by the heating element, and the heating efficiency and energy utilization rate can be improved. Moreover, the relatively large contact area can also avoid the heat concentration and the burning of the side wall 21332 of the plate. In addition, the side wall 21332 of the plate being a curved wall can make the space enclosed by the side wall and the bottom of the plate smaller (for example, the height of the heating plate is reduced to make the enclosed space smaller). In the case where the grinding assembly includes a knife assembly, the small space can make the turbulence effect better, and further avoid the food from sticking to the bottom of the plate and / or the side wall of the plate.

[0058] like Figure 6 , Figure 5 and Figure 4 As shown, the cavity 2134 enclosed by the disk sidewall 21332 and the disk bottom 21331 gradually increases in size in a direction away from the disk bottom 21331. Figure 5 As shown by arrow f.

[0059] As configured above, since the cavity 2134 gradually increases in size in the direction away from the bottom 21331 of the dish, the space is kept small so as to achieve a good turbulence effect, further preventing food from sticking to the bottom and / or side walls of the dish.

[0060] See also Figure 1 , Figure 2 and Figure 3 On the other hand, the present application discloses a food processor, which includes a main unit 3, a blending cup 22 and any one of the aforementioned grinding components 21. The disk 2133 is disposed at the bottom of the blending cup 22, and the main unit 3 includes a driving device and a control panel, and the control panel controls the driving device to drive one of the inner grinding head 211 and the outer grinding head 212 to rotate relative to the other, and controls the heating element 2131 to heat. In an embodiment of the present application, the blending cup 22, the grinding component 21 and the handle component 23 fixed to the blending cup 22 together constitute a blending cup component 2, and a cup cover component 1 is provided on the top of the blending cup component 2. The main unit 3 also includes a cup holder 31 and a bottom cover 32, and the bottom cover 32 is assembled with the cup holder 31.

[0061] like Figure 6 , Figure 5 and Figure 8 Combined with Figure 3 and Figure 1As shown, the heating plate 213 is fixed between the cup holder 31 and the bottom cover 32, and the bottom cover 32 is assembled with the cup holder 31 and includes a receiving cavity 321. The food processor also includes a fixing ring 214 and a sealing member 215 fixed to the fixing ring 214. The plate bottom 21331 includes a mounting hole penetrating the plate bottom 21331. The outer grinding head 212 includes a mounting section 2122.

[0062] Based on the above structure, the assembly process of the outer grinding head 212 (or the assembly consisting of the outer grinding head 212 and the inner grinding head 211) is as follows:

[0063] First, the inner grinding head 211 is fixed to the rotating shaft 2162, and the rotating shaft 2162 is rotatably connected to the bearing assembly 216 inside the mounting section 2122, so that the inner grinding head 211, the outer grinding head 212 and the rotating shaft 2162 are assembled into a whole.

[0064] Secondly, the mounting section 2122 passes through the mounting hole; the fixing ring 214 and the sealing member 215 are both located in the accommodating cavity 321, and the fixing ring 214 is connected to the mounting section 2122 by threads. As the threads are tightened, the tensioning force causes the outer grinding head 212 to press against the disc bottom 21331. The sealing member 215 is in sealing contact with the cavity wall of the accommodating cavity 321. Of course, based on the idea of ​​generating tension by the threaded connection, the threads can also be replaced by a buckle structure.

[0065] As set up above, the threaded connection or snap connection is achieved by rotating the fixing ring 214, and then the outer grinding head 212 (or the assembly consisting of the outer grinding head 212 and the inner grinding head 211) is assembled or disassembled from the heating plate 213, thereby facilitating the assembly and disassembly of the outer grinding head 212 (or the assembly consisting of the outer grinding head 212 and the inner grinding head 211).
