Description

Technical Field

[0001] This invention relates to household appliances, and in particular to a stable food processing machine. Background Technology

[0002] To enhance the product's appearance, existing food processing machines, such as soy milk makers and blenders, are designed with a uniform cylindrical shape from top to bottom. This means that all components except the handle are housed within a cylinder. To accommodate these components within the limited horizontal space, the overall height of the machine is increased.

[0003] To lower the machine's center of gravity, the processing motor is typically placed below the machine body or cup assembly. For example, the blender disclosed in utility model patent CN211299644U (hereinafter referred to as patent 1) has the drive device 2 installed in the lower chamber 107, which is located below the stirring chamber 503. However, the stirring chamber 503 is a cylindrical cavity. Under the rotation of the blade assembly 6, the liquid spirals upward within the stirring chamber 503. This regular flow of liquid reduces the contact between the material and the blade assembly 6, resulting in low pulverization efficiency and effect. Especially for large-capacity models, since the blade assembly 6 is located at the bottom of the stirring chamber 503, when preparing large quantities of material, the material spirals upward with the liquid to the upper part of the stirring chamber 503, making it difficult for it to fall back to the vicinity of the blade assembly 6 at the bottom. This creates a pulverization blind zone, significantly reducing the chance of material contact with the blade assembly 6 and affecting the overall uniformity of material pulverization, leading to even worse pulverization efficiency and effect.

[0004] Therefore, in order to improve the crushing efficiency and effect, existing technologies often place the processing motor on the machine head. For example, a blender disclosed in utility model patent CN215457447U (hereinafter referred to as patent 2) has the motor 08 installed inside the machine head 1. Since part of the machine head extends into the inner cavity of the glass, it occupies part of the space inside the glass, reducing the space inside the glass. When the liquid flows in the inner cavity of the glass, it will encounter resistance and fall back when it hits the machine head, thereby changing the flow path of the liquid and increasing the probability of contact between the material in the liquid and the crushing blade 12. Therefore, the crushing efficiency and effect can be improved. Especially when making large-volume materials, the part of the machine head that extends into the inner cavity of the glass can greatly increase the chance of the material encountering resistance and falling back when it hits the machine head, greatly increasing the probability of contact between the material and the crushing blade, thereby improving the uniformity of material crushing and thus improving the crushing efficiency and effect of the material. However, the model with the motor mounted on top in Patent 2 has a higher center of gravity than the model with the motor mounted on the bottom in Patent 1, which affects the stability of the food processing machine. The food processing machine is prone to being top-heavy during operation, resulting in greater vibration and noise, and may even tip over. Summary of the Invention

[0005] The purpose of this invention is to provide a stable food processing machine that, while ensuring the crushing efficiency and effect of the head-mounted food processing machine and meeting the production capacity requirements, solves the problem of poor working stability of the food processing machine, effectively lowers the center of gravity of the machine, and increases its working stability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a stable food processing machine, comprising a machine head and a cup assembly with a processing motor inside. The cup assembly includes a cup body, a connecting bracket, and a shell. The connecting bracket is fitted onto the outer bottom of the cup body and fixedly connected to the outer bottom of the cup body. The shell is fitted onto the outer side of the connecting bracket and fixedly connected to the connecting bracket. The height of the upper edge of the fixed connection point between the connecting bracket and the outer bottom of the cup body from the inner bottom surface of the shell is h1. The height of the top surface of the cup body from the inner bottom surface of the shell is h2, 0.3≤h1 / h2≤0.45. The height of the outer bottom surface of the cup body from the inner bottom surface of the shell is H, 35mm≤H≤80mm.

[0007] Furthermore, the cup assembly also includes a circuit board. The bottom of the connecting bracket has an extension extending toward the bottom surface of the housing. The inner side of the extension forms a first receiving space, and the circuit board is fixed within the first receiving space. The height of the circuit board from the bottom surface of the housing is no more than 0.5H. By adopting the aforementioned technical solution, not only is the height of the circuit board reduced, but the overall center of gravity of the cup assembly is also lowered. Furthermore, the height of the first receiving space can be compressed, preventing an increase in the height of the connecting bracket. The first receiving space can constrain the circuit board, improving the stability and reliability of the circuit board after it is fixed.

[0008] Furthermore, the extension includes a plurality of support columns extending toward and fixed to the bottom surface of the housing, the plurality of support columns defining a first receiving space;

[0009] Alternatively, the extension includes a limiting ring extending towards the bottom surface of the housing. The inner wall of the limiting ring defines a first receiving space, and a gap for drainage is formed between the outer side of the limiting ring and the inner wall of the housing. Using the first technical solution, because there is a large gap between adjacent support columns, it is less likely to collide with the circuit board during installation, thus reducing installation efficiency and facilitating heat dissipation. In another technical solution, the limiting ring surrounds the circuit board, providing better stability. Simultaneously, the gap between the outer side of the limiting ring and the inner wall of the housing allows water entering the housing to flow downwards quickly and promptly, preventing water from lingering on the connecting bracket and flowing onto the circuit board. This effectively prevents the circuit board from contacting water during normal use. Furthermore, drainage holes can be provided on the bottom surface of the housing to promptly drain water from the inside, preventing water accumulation on the bottom of the housing from contacting the circuit board.

[0010] Furthermore, the extension is provided with a plurality of limiting ribs for increasing the strength of the connecting bracket, and the limiting ribs laterally limit the circuit board;

[0011] Alternatively, the cup assembly may further include a circuit board bracket, with the circuit board mounted on the bracket and fixed within the first receiving space. The extension has multiple limiting ribs to increase the strength of the connecting bracket, and these ribs laterally limit the circuit board bracket. Using the first technical solution, the limiting ribs can improve the structural strength of the extension and also laterally limit the circuit board. By contacting the circuit board with the limiting ribs, the contact area between the extension and the circuit board is reduced, enabling multi-point positioning of the circuit board. This facilitates effective heat dissipation gaps around the circuit board, ensuring long-term reliable operation of the components on the circuit board. In another technical solution, adding a circuit board bracket facilitates encapsulating the circuit board within the bracket, further improving the long-term reliability of the circuit board.

[0012] Furthermore, the connecting bracket includes a partition, forming a second accommodating space above the partition and a first accommodating space below the partition. The height of the second accommodating space is H2, and the height of the first accommodating space is H1, where H2 > H1. Using the aforementioned technical solution, the heater can be located within the second accommodating space, separated from the first accommodating space and from the circuit board assembly, reducing the thermal impact of the heater on the circuit board assembly. The fact that H2 is larger than H1 serves two purposes: firstly, it lowers the height of the partition, allowing the center of gravity of the connecting bracket to be at a lower position; secondly, it increases the volume of the second accommodating space, facilitating the placement of components such as the heater and temperature controller, and maintaining a thermal insulation gap between the heater and the connecting bracket, further reducing the impact of the heat generated by the heater on the circuit board.

[0013] Furthermore, the cup assembly also includes a circuit board and a circuit board bracket. The circuit board is horizontally fixed within the circuit board bracket, and the circuit board bracket is installed within the first accommodating space and fixed against the partition. By adopting the aforementioned technical solution, since the circuit board bracket and the connecting bracket are fixed as one unit, the weight of the circuit board bracket can further reduce the center of gravity of the combined structure with the connecting bracket.

[0014] Furthermore, the partition is provided with a through hole, which is covered by the circuit board bracket from bottom to top. By adopting the aforementioned technical solution, on the one hand, the addition of the circuit board bracket helps to lower the center of gravity of the cup assembly. Furthermore, the addition of the through hole reduces the amount of material used in the partition, lowering costs. On the other hand, when it is necessary to inspect the components in the second accommodating space, only the circuit board bracket needs to be disassembled, without disassembling the connecting bracket, which greatly facilitates the inspection and maintenance of the components in the second accommodating space.

[0015] Furthermore, the cup body includes a glass cup body and a heating plate. The bottom end of the glass cup body is open. The top end of the connecting bracket is connected to the glass cup body and fixes the heating plate to the bottom end of the glass cup body. The heating plate is sunk into the connecting bracket and forms a crushing chamber. The outer bottom surface of the heating plate forms the outer bottom surface of the cup body.

[0016] Alternatively, the cup body is a glass cup body, the bottom of the glass cup body is closed, and the outer bottom surface of the glass cup body is the outer bottom surface of the cup body;

[0017] Alternatively, the cup body includes a glass cup body with an open bottom. The top of the connecting bracket forms a heating plate, and the top of the heating plate is fitted onto the outer bottom of the glass cup body and fixedly connected to it. Using the first technical solution, compared to the flat structure of the heating plate in existing technologies, with the same production capacity, allowing the heating plate to sink into the connecting bracket and form a pulverizing chamber lowers the liquid level, further reducing the machine's center of gravity during operation. The smaller volume of the pulverizing chamber formed by the heating plate allows for pulverizing in a small space, improving pulverizing efficiency and effect. Using the second technical solution, the glass cup body has higher integrity and strength, and the bottom wall of the glass cup body lowers the center of gravity of the cup body, which also helps to lower the machine's center of gravity. Using the third technical solution, integrating the heating plate into the connecting bracket increases the weight of the connecting bracket, lowering the overall center of gravity of the cup body assembly.

[0018] Furthermore, the connecting bracket is provided with an upwardly extending connecting ring, which defines a second receiving space. The connecting ring is fixedly connected to the bottom of the cup body. A handle is provided on the outer side of the cup body assembly, with the top end of the handle fixed to the mouth of the cup body and the bottom end of the handle fixedly connected to the connecting ring. By adopting the aforementioned technical solution, not only can better heat insulation be achieved, but the connecting ring structure also has higher strength, can be used to connect both the cup body and the handle, and increases the weight of the connecting bracket, thus lowering the overall center of gravity of the cup body assembly.

[0019] Furthermore, the top of the shell has a first constriction, and the bottom of the cup has a second constriction. The first constriction is fitted around the outer periphery of the second constriction and fixedly connected to form an annular cavity. A decorative ring is provided on the outer periphery of the first constriction, and the decorative ring is located within the annular cavity. By adopting the aforementioned technical solution, because the structural strength of the constriction is relatively improved, the fitting and fixing of the first and second constrictions not only achieves a better connection and fixation effect, but the shell can also protect the bottom periphery of the cup, reducing the possibility of the cup breaking upon impact. The decorative ring can enhance the aesthetics of the machine, and placing the decorative ring within the annular cavity can reduce the likelihood of wear on the decorative ring, increasing its service life.

[0020] After adopting the above technical solution, the present invention has the following advantages: First, the processing motor is placed inside the machine head to ensure better crushing efficiency and effect. Under the premise of meeting the production capacity requirements, that is, the inner cavity volume of the cup will not be reduced. In order to lower the center of gravity of the machine, the internal space structure of the shell is designed. First, a connecting bracket is used to connect and fix the cup body to the housing in the vertical direction, achieving a top-to-bottom connection between the cup body, connecting bracket, and housing. This allows the bottom of the housing to support the cup body, ensuring the stability of the cup assembly when placed. Second, by limiting the appropriate height of the connection between the connecting bracket and the cup body, the center of gravity of the connecting bracket is effectively limited. This ensures that the connecting bracket, in addition to connecting and fixing the cup body to the housing, can also lower the machine's center of gravity. This not only lowers the center of gravity of the connecting bracket itself but also lowers the center of gravity of the cup assembly through its combined effect, thereby lowering the machine's center of gravity. Finally, the height of the internal installation space of the housing is controlled. H must not only accommodate the installation of components such as the connecting bracket, circuit board, and temperature controller but also not exceed the height of commonly used processing motors, ensuring that the overall height of the cup assembly is lowered, thus lowering its center of gravity.

[0040] It should be understood that in this invention, "multiple" refers to two or more.

[0041] The following is for reference. Figures 1 to 6 The technical solutions of the present invention will be described in detail with reference to specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0042] like Figure 1As shown, this invention provides a stable food processing machine, including a machine head 1 with a processing motor 11 inside and a cup assembly. The cup assembly includes a cup body 2, a connecting bracket 3, and a housing 4. In this invention, the processing motor 11 is placed inside the machine head 1 to ensure better pulverization efficiency and effect. Under the premise of meeting the production capacity requirements, that is, the internal volume of the cup body 2 will not decrease. In order to lower the center of gravity of the machine, the internal spatial structure of the housing 4 is designed. Specifically, the connecting bracket 3 is fitted onto the bottom outer side of the cup body 2 and fixedly connected to the bottom outer side of the cup body 2. The housing 4 is fitted onto the outside of the connecting bracket 3 and fixed to the bottom end of the connecting bracket 3. Thus, the connecting bracket 3 is used to achieve the connection and fixation of the cup body 2 and the housing 4 in the height direction. This design achieves a top-to-bottom connection and fixation between the cup body 2, connecting bracket 3, and housing 4, allowing the bottom of housing 4 to support the cup body 2 and ensure the stability of the cup assembly when placed. The height of the upper edge of the fixed connection point between the connecting bracket 3 and the bottom outer side of the cup body 2 from the inner bottom surface of housing 4 is h1, and the height of the top surface of the cup body 2 from the inner bottom surface of housing 4 is h2, where 0.3 ≤ h1 / h2 ≤ 0.45. For example, h1 / h2 can be chosen as 0.3, 0.32, 0.35, 0.38, 0.4, 0.42, or 0.45, etc. By limiting the appropriate height of the fixed connection between the connecting bracket 3 and the cup body 2, the center of gravity height of the connecting bracket 3 is effectively limited, ensuring that the connecting bracket 3, in addition to supporting the cup body 2 and housing 4, also ensures the stability of the cup assembly. The connection and fixation of component 4 can also be used to lower the machine's center of gravity. Compared to the motherboard frame in the existing technology CN215457447U, it not only lowers the center of gravity of the connecting bracket 3 itself, but also lowers the center of gravity of the cup assembly by having a combined effect on it, thereby lowering the machine's center of gravity. Since this invention is aimed at a cylindrical model with a basically uniform size from top to bottom, the installation space cannot be increased laterally. In order to reserve space for installing other components, such as circuit boards and temperature controllers, h1 should not be too small, that is, h1 / h2 is generally not less than 0.3. Moreover, if h1 is too small, the height dimension of the connecting bracket 3 is limited, and the weight reduction makes it difficult to have a combined effect on the cup assembly to lower its center of gravity. If h1 / h2 exceeds 0.45, the effect of lowering the center of gravity cannot be significantly achieved, so it is also undesirable. In addition, the height of the installation space inside the shell 4 is also controlled. Specifically, the height H between the outer bottom surface of the cup body 2 and the inner bottom surface of the shell 4 is 35mm≤H≤80mm. For example, H can be selected as 35mm, 40mm, 44mm, 48mm, 50mm, 55mm, 60mm, 66mm, 70mm, 72mm, 78mm or 80mm, etc. That is, in addition to meeting the installation of components such as the connecting bracket 3, circuit board 5, and temperature controller, H should not exceed the height of the commonly used processing motor 11 to ensure that the height of the entire cup body assembly can be lowered, thereby lowering its center of gravity.If H is too small, the reason is similar to that if h1 is too small: the height of the connecting bracket 3 is limited, and the weight decreases, making it difficult to have a combined effect on the cup assembly to lower its center of gravity. If H is too large, it will increase the installation height of the cup 2, which will undoubtedly increase the center of gravity of the entire cup assembly. Using metal or high-density plastic for the connecting bracket 3 will be more effective in lowering the center of gravity.

[0043] In one embodiment, the bottom end of the connecting bracket 3 can be fixedly connected to the inner bottom surface of the housing 4. In another embodiment, the bottom end of the connecting bracket 3 can also be fixedly connected to the bottom end of the inner side surface of the housing 4. Specifically, regarding the fixing method between the connecting bracket 3 and the outer bottom of the cup body 2, a threaded connection can be used. For example, in one embodiment, an internal thread is provided on the inner top side of the connecting bracket 3 and extends to the top surface. Therefore, the upper edge of the fixing connection point between the connecting bracket 3 and the outer bottom of the cup body 2 can be considered the top surface of the connecting bracket 3. In another embodiment, after the connecting bracket 3 and the outer bottom of the cup body 2 are fixedly connected, the top of the connecting bracket 3 can continue to extend upwards to a certain height, and the upper edge of the fixing connection point between the connecting bracket 3 and the outer bottom of the cup body 2 will be lower than the top surface of the connecting bracket 3. Alternatively, the connecting bracket 3 and the cup body 2 can also be connected using common methods such as adhesive bonding.

[0044] In one embodiment, the cup assembly further includes a circuit board 5. To install and fix the circuit board 5 without affecting the connection and fixation between the connecting bracket 3 and the housing 4, an extension extending towards the bottom surface of the housing 4 can be provided at the bottom of the connecting bracket 3. A first receiving space 301 is formed on the inner side of the extension. The circuit board 5 is fixed in the first receiving space 301. The height H' of the circuit board 5 from the inner bottom surface of the housing 4 is not greater than 0.5H. This not only lowers the height position of the circuit board 5, but also helps to lower the overall center of gravity of the cup assembly. It also compresses the height of the first receiving space 301, preventing an increase in the height of the connecting bracket 3. The circuit board 5 can be a power circuit board 5, an operation circuit board 5, etc. The first receiving space 301 can constrain the circuit board 5, improving the stability and reliability of the circuit board 5 after it is fixed. When the area of ​​the circuit board 5 is large, it needs to be placed horizontally in the first receiving space 301. In short, the smallest size is selected as the height dimension.

[0045] Specifically, the extension can adopt different structural forms, such as reference Figure 2 and Figure 3In one embodiment, the extension includes a plurality of support columns 31 extending toward and fixed to the bottom surface of the housing 4, defining a first accommodating space 301. Because there is a large gap between adjacent support columns 31, it is less likely to collide with the circuit board 5 during installation, thus reducing the installation efficiency of the circuit board 5 and also facilitating heat dissipation of the circuit board 5. In another embodiment, the extension may also include a limiting ring extending toward the bottom surface of the housing 4. The inner wall of the limiting ring defines the first accommodating space 301. The limiting ring can surround the circuit board 5, providing better stability for its fixation. Simultaneously, a gap for drainage is formed between the outer side of the limiting ring and the inner wall of the housing, allowing water entering the housing to flow downwards quickly and promptly, preventing water from lingering on the connecting bracket and flowing onto the circuit board. This effectively prevents the circuit board from contacting water during normal use. Additionally, drainage holes can be provided on the bottom surface of the housing to promptly drain water entering the housing, preventing water accumulation on the bottom of the housing from contacting the circuit board.

[0046] To improve the structural strength of the extension, multiple limiting ribs 32 can be provided on the extension to increase the strength of the connecting bracket 3. For example, the limiting ribs 32 can be provided on the side of the support column 31, which can also improve the strength of the support column 31. At the same time, the limiting ribs 32 can be used to laterally limit the circuit board 5. By contacting the circuit board 5 with the limiting ribs 32, the contact area between the extension and the circuit board 5 is reduced, and multi-point positioning of the circuit board 5 can be achieved. This is conducive to obtaining an effective heat dissipation gap on the outer periphery of the circuit board 5, which is beneficial to heat dissipation of the circuit board 5 and ensures the long-term reliable operation of the components on the circuit board 5.

[0047] In addition to directly fixing the circuit board 5 to the first accommodating space 301, in another embodiment, the cup assembly can also be designed to include a circuit board bracket 51. Specifically, the circuit board 5 is first installed on the circuit board bracket 51, and the circuit board 5 is fixed in the first accommodating space 301 by the circuit board bracket 51. This makes it easier to encapsulate the circuit board 5 in the circuit board bracket 51, further improving the reliability of the circuit board 5 in long-term operation. In order to improve the structural strength of the extension and limit the circuit board bracket 51, the extension is provided with a plurality of limiting ribs 32 for increasing the strength of the connecting bracket 3. The limiting ribs 32 laterally limit the circuit board bracket 51.

[0048] Since a heater, such as a heating element or heating film, is typically installed at the bottom of the cup body 2, a connecting bracket 3 can be designed, including a partition 33. The connecting bracket 3 forms a second receiving space 302 above the partition 33 and a first receiving space 301 below the partition 33. The height of the second receiving space 302 is H2, and the height of the first receiving space 301 is H1, where H2 > H1. The heater can be located within the second receiving space 302, separated from the first receiving space 301 and from the circuit board assembly, thus reducing the thermal impact of the heater on the circuit board assembly. H2 can be understood as the vertical height from the upper surface of the partition 33 to the top surface of the connecting bracket 3. If the connecting bracket 3 has an upwardly extending connecting ring 34, then the top surface of the connecting ring 34 is the top surface of the connecting bracket 3. The bottom end of the cup 2 can also extend into the second accommodating space 302 and connect with the connecting ring 34. H1 can be understood as the vertical height from the lower surface of the partition 33 to the bottom surface of the connecting bracket 3. If the bottom of the connecting bracket 3 has a downwardly extending support column 31, then the bottom surface of the support column 31 is the bottom surface of the connecting bracket 3. H2 is larger than H1. On the one hand, it lowers the height of the partition 33, which can lower the center of gravity of the connecting bracket 3. On the other hand, it can increase the volume of the second accommodating space 302, which is beneficial for setting up components such as heaters and temperature controllers and maintaining a heat insulation gap between the heater and the connecting bracket 3, further reducing the impact of the heat generated by the heater on the circuit board 5. Considering the need to accommodate both the lower center of gravity and heat insulation effects, the connecting bracket 3 can be made of a plastic with a larger sealing capacity.

[0049] The circuit board 5 can be directly fixed in the first accommodating space 301 and installed on the partition 33. Alternatively, the circuit board assembly can include the circuit board 5 and the circuit board bracket 51, with the circuit board 5 horizontally fixed to the circuit board bracket 51. The circuit board bracket 51 is installed in the first accommodating space 301 and fixed against the partition 33. Since the second accommodating space 302 needs to house some components, a through hole 331 can be provided in the partition 33 to improve the convenience of maintenance. The circuit board bracket 51 covers the through hole 331 from bottom to top. On the one hand, the addition of the circuit board bracket 51 helps to lower the center of gravity of the cup assembly. On this basis, the addition of the through hole 331 can reduce the amount of material used in the partition and reduce costs. On the other hand, when it is necessary to maintain the components in the second accommodating space 302, only the circuit board bracket 51 needs to be removed, without disassembling the connecting bracket 3. The circuit board bracket 51 covers the through hole 331 from bottom to top, sealing the through hole 331. This effectively reduces the amount of heat from the second accommodating space entering the first accommodating space through the through hole 331, thus reducing the impact of the heater's heat on the circuit board.

[0050] To achieve better heat insulation, an upwardly extending connecting ring 34 can be provided on the connecting bracket 3. Specifically, this refers to a protruding ring on the partition 33. The connecting ring 34 not only defines the second receiving space 302 but also is fixedly connected to the bottom of the cup body 2. A handle 6 is provided on the outer side of the cup body assembly. The top end of the handle 6 is fixed to the mouth of the cup body 2, and the bottom end of the handle 6 is also fixedly connected to the connecting ring 34. The connecting ring 34 not only has higher structural strength and can be used to connect both the cup body 2 and the handle 6, but also increases the weight of the connecting bracket 3 and lowers the overall center of gravity of the cup body assembly.

[0051] Combination Figure 2 and Figure 4 In one embodiment, the top of the housing 4 has a first constriction 401, and the bottom of the cup 2 has a second constriction 201. The first constriction 401 fits around the second constriction 201, forming an annular cavity 200. A decorative ring 7 is provided on the outer periphery of the first constriction 401, and the decorative ring 7 is located within the annular cavity 200. Because the structural strength of the constriction is relatively improved, the first constriction 401 and the second constriction 201 are fitted and fixed together, which not only achieves a better connection and fixation effect, but also allows the housing 4 to protect the bottom periphery of the cup 2, reducing the possibility of the cup 2 breaking due to impact. The decorative ring 7 can increase the aesthetics of the machine, and placing the decorative ring 7 within the annular cavity 200 can reduce the probability of wear on the decorative ring 7 and increase its service life. In another embodiment, the top of the housing 4 can be lower than the top of the connecting bracket 3, which is equivalent to wrapping a part of the connecting bracket 3. In another embodiment, the top of the housing 4 can continue to extend upward to wrap the cup 2, reaching as high as the outer side of the top port of the cup.

[0052] In one embodiment, the cup body 2 includes a glass cup body 21 and a heating plate 22. The bottom end of the glass cup body 21 is open. The top end of the connecting bracket 3 is connected to the glass cup body 21 and fixes the heating plate 22 to the bottom end of the glass cup body 21. The heating plate 22 sinks into the connecting bracket 3 and forms a crushing chamber 221. The outer bottom surface of the heating plate 22 forms the outer bottom surface of the cup body 2. The structure of the heating plate 22 can generally be a metal plate and a heating tube. The heating tube is fixed to the outer wall of the metal plate. A sealing gasket 23 can be set between the bottom of the glass cup 21 and the heating plate 22 to improve the sealing performance. To increase the reliability of the connection and fixation between the glass cup 21 and the heating plate 22, the sealing gasket 23 and the connecting bracket 3, a positioning step 35 can be set on the inner side of the top of the connecting bracket 3. The edge of the heating plate 22 is provided with a flange 222. After the glass cup 21 and the connecting bracket 3 are connected in place, the bottom surface of the glass cup 21 presses the sealing gasket 23 and the flange 222 of the heating plate 22 onto the positioning step 35. The inner side of the top of the connecting bracket 3 can also restrict the sealing gasket 23 from deforming outward to ensure that it reliably seals the bottom surface of the glass cup 21 and the flange 222 of the heating plate 22. Compared to the flat structure of the heating plate 22 in existing technologies, by submerging the heating plate 22 into the connecting bracket 3 to form the pulverizing chamber 221 for the same production capacity, the liquid level will decrease, allowing the machine's center of gravity to be further lowered during operation. Furthermore, the pulverizing chamber 221 formed by the heating plate 22 has a smaller volume, enabling pulverization in a smaller space, which is beneficial for improving pulverization efficiency and effectiveness.

[0053] like Figure 5 As shown, in one embodiment, the cup body is a glass cup body 21, the bottom of the glass cup body 21 is closed, and the outer bottom surface of the glass cup body 21 is the outer bottom surface of the cup body. To achieve heating, a heating film 211 can be attached to the outer bottom surface of the glass cup body 21. In this embodiment, since a heating film is used instead of a heating tube, the space occupied is reduced, so H can be selected with a smaller value, further lowering the center of gravity of the machine.

[0054] like Figure 6 As shown, in one embodiment, the cup body is a glass cup body 21 with an open bottom. A heating plate 22 is formed on the top of the connecting bracket 3, and the top of the heating plate 22 is fitted over the outer bottom of the glass cup body 21 and fixedly connected to it. The heating plate 22 is integrated into the connecting bracket 3, which increases the weight of the connecting bracket 3 and lowers the overall center of gravity of the cup assembly. In this embodiment, since the heating plate 22 and the connecting bracket 3 form an integral structure, H can be selected as a smaller value.

[0055] In addition to the preferred embodiments described above, the present invention has other embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection claimed by the present invention.
