Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a soybean milk machine. Background Art

[0002] The invention patent with application number 200910246661.1 discloses a food processing machine, wherein a sanitary protective sleeve is provided at the lower end of the machine head, a heating part made of metal material is provided at the lower part of the sanitary protective sleeve, and a heating device connected to the heating part by heat conduction is provided at the heating part, and the heat of the heating device can be dissipated to various parts of the heating part, thereby expanding the heating area, solving the problem of slurry burning, and achieving high thermal efficiency. However, since an upper connecting part connected to the machine head is provided at the upper end of the sanitary protective sleeve, and the motor is wrapped in the lower cover of the machine head, the motor and the heating device are installed in the same installation cavity surrounded by the sanitary protective sleeve and the upper cover of the machine head, and the installation cavity cannot be directly connected to the outside world to form a closed cavity, and the installation cavity cannot directly communicate with the outside world for airflow conduction. When the heating device is working, the air pressure in the closed installation cavity increases, which easily causes the gas in the sanitary protective sleeve to expand and deform the protective sleeve, or even rupture and damage, posing a safety hazard. In addition, the hot air flow from the heating device will be directly transferred to the motor, and the motor is immersed in the boiling slurry at the same time, causing the temperature of the motor to rise higher, posing a risk of burning out the motor and reducing the life of the motor. Utility Model Content

[0003] The utility model provides a soymilk machine which, based on utilizing a machine head to heat a cup body, solves the problems in the prior art of deformation of the machine head and potential safety hazards caused by increased air pressure in the installation cavity during operation due to the closed installation cavity where the heating device is located, and the problem of increased temperature of the motor caused by greater radiation heat from the heating device to the motor.

[0004] The technical solution adopted by the utility model is:

[0005] The utility model provides a soymilk machine, comprising a cup body and a machine head buckled on the cup body, the machine head comprising a metal lower cover, an upper cover covering the metal lower cover, a mounting seat arranged in the metal lower cover, a motor and a heating element, the mounting seat is provided with a mounting cavity, the motor is fixedly installed in the mounting cavity, the rotating shaft of the motor passes through the mounting seat and the metal lower cover, extends into the cup body and is connected to a crushing knife, a heating cavity for installing the heating element is provided between the mounting seat and the metal lower cover, the heating cavity is isolated from the mounting cavity and are not connected to each other, and the upper cover is provided with an air vent for connecting the heating cavity with the outside.

[0006] The soymilk maker provided by the utility model has an installation cavity provided in the installation base, the motor is fixedly installed in the installation cavity, and a heating cavity for installing the heating element is provided between the installation base and the metal lower cover, so that the heating element and the motor can be installed in two different spaces respectively, and the heating cavity and the installation cavity are isolated and not connected to each other. Therefore, the heat generated by the heating element during operation is only diffused in the heating cavity and then transferred to the liquid in the cup body through the metal lower cover, which can improve the slurry heating efficiency. At the same time, the heat of the heating element will not directly flow into the installation cavity for installing the motor, thereby achieving isolation between the motor and the heat, preventing a large amount of heat from the heating element from being transferred to the motor, and at the same time, the heating cavity is used to form an air layer to have a heat insulating effect between the installation cavity and the high-temperature slurry in the cup body, preventing the heat of the high-temperature slurry from being transferred to the motor, thereby improving the temperature rise of the motor and extending the service life of the motor. In addition, by arranging an air hole in the upper cover to connect the heating chamber with the outside world, when the heating element is in working state, the hot air in the heating chamber expands and the air pressure rises. The heating chamber can achieve air pressure balance with the outside world through the air hole, thereby preventing safety problems caused by excessive pressure in the heating chamber. The use is safe and the metal lower cover is prevented from expanding and deforming, thereby ensuring a reliable connection with the upper cover and a reliable machine head structure. In addition, when the heating element stops working, the air temperature in the heating chamber drops, and the cold air from the outside enters the heating chamber through the air hole to take away the heat in the heating chamber, dissipate the heat from the heating element, prevent the machine head from being hot or the slurry from sticking to the metal lower cover of the machine head, and indirectly take away the heat of the motor in the heating chamber, indirectly dissipate the heat from the motor in the installation chamber, thereby extending the service life of the motor.

[0007] In a preferred embodiment, an opening is provided at the upper end of the mounting seat, a first mounting portion and a second mounting portion located radially outward of the first mounting portion are provided at the bottom of the upper cover, the upper end of the mounting seat is sealingly connected to the first mounting portion so that the upper cover and the mounting seat enclose the mounting cavity, and the upper end of the metal lower cover is fixedly connected to the second mounting portion.

[0008] By setting an opening at the upper end of the mounting seat, it is convenient to install the motor into the mounting seat, and the assembly is simple. At the same time, the upper end of the mounting seat is sealed and connected to the first mounting part so that the upper cover and the mounting seat can enclose the mounting cavity to form the mounting cavity, thereby realizing sealed isolation between the mounting cavity and the heating cavity. The hot air flow in the heating cavity cannot flow into the mounting cavity, thereby reducing the heat radiation of the heating element to the motor and improving the temperature rise of the motor. Moreover, the first mounting part and the second mounting part are respectively used to limit the mounting seat and the metal lower cover, so that enough space is reserved between the first mounting part and the second mounting part for the heating cavity to directly communicate with the air vent through the outside of the mounting seat. There is no need to set up a separate conducting structure, which simplifies the internal structure of the machine head, simplifies the installation of the mounting seat, ensures the stable connection between the mounting seat, the metal lower cover and the upper cover, and improves the overall structural reliability of the machine head.

[0009] In a preferred embodiment, a sealing member is provided between the first mounting portion and the mounting seat, and the mounting seat is fixedly mounted in the metal lower cover. After the metal lower cover is fixedly connected to the second mounting portion, the mounting seat and the first mounting portion clamp the sealing member;

[0010] In a preferred embodiment, the first mounting portion is a rib extending downward, the mounting seat is screwed onto the rib and a sealing member is sandwiched between the mounting seat and the rib.

[0011] By providing a sealing member between the first mounting portion and the mounting seat, on the one hand, the sealing isolation effect between the mounting cavity and the heating cavity is further improved; on the other hand, after the metal lower cover is fixedly connected to the second mounting portion, the mounting seat and the first mounting portion clamp the sealing member, which is beneficial for the sealing member to also play the role of a soft connection between the first mounting portion and the mounting seat, thereby preventing the increase of the overall tolerance caused by the matching process between the metal lower cover and the upper cover, and making the assembly and fixation more reliable.

[0012] In a preferred embodiment, an opening and a first flange extending outward from the opening are provided at the upper end of the mounting seat, the first flange is sealingly overlapped on the top of the metal lower cover so that the mounting seat and the metal lower cover are enclosed to form the heating chamber, and an air guide tube is provided between the upper cover and the mounting seat, and an air passage connecting the heating chamber with the air vent is formed inside the air guide tube.

[0013] An opening is arranged at the upper end of the mounting seat and a first flange extending outward from the opening, so that the first flange is supported on the top of the metal lower cover, and pre-fixation is achieved during the assembly process of the machine head, which is convenient for assembly. The mounting seat and the metal lower cover are then combined to form the heating chamber, thereby improving the sealing and waterproof properties of the heating chamber, achieving sealed isolation between the mounting chamber and the heating chamber, and the hot air flow in the heating chamber cannot flow into the mounting chamber, thereby reducing the heat radiation of the heating element to the motor and improving the temperature rise of the motor. An air guide tube is arranged between the upper cover and the mounting seat, and an air permeable channel is formed inside the air guide tube to connect the heating chamber with the air vent, so that the heating chamber can be smoothly connected with the outside world, thereby achieving stable air pressure during operation, preventing deformation of the metal lower cover, and improving safety in use.

[0014] In a preferred embodiment, one end of the air guide cylinder is fixed to the upper cover and communicated with the air vent, and the other end passes through the mounting seat and extends into the heating chamber;

[0015] Alternatively, one end of the air guide cylinder is fixed to the mounting seat and communicated with the heating chamber, and the other end of the air guide cylinder and the mounting chamber are both communicated with the outside through the air vent.

[0016] No matter one end of the air guide cylinder is fixed directly to the upper cover or to the mounting seat, it can realize smooth conduction between the heating chamber and the outside world, ensuring safe use. Since the upper cover has a simple structure, the air guide cylinder is installed on the upper cover, which is convenient for production and manufacturing. During the assembly process, the air guide cylinder is inserted through the mounting seat and extended into the heating chamber to cooperate with the mounting seat, which makes the assembly simple and reliable. One end of the air guide cylinder is fixedly installed on the mounting seat, and the other end of the air guide cylinder and the mounting chamber are connected to the outside world through the air vent. While achieving heat dissipation of the motor, the air vent is shared, and there is no need to set another through hole on the upper cover to dissipate heat from the mounting chamber of the motor, and the structure is simple.

[0017] In a preferred embodiment, the top of the metal lower cover is provided with a second flange extending outward to support the first flange, a sealing ring is crimped between the first flange and the second flange, and the first flange, the second flange and the upper cover are fixed together.

[0018] By providing a second flange extending outward on the top of the metal lower cover, a larger matching area is provided between the mounting seat and the metal lower cover, thereby improving the sealing of the connection position, thereby ensuring the isolation effect between the mounting cavity and the heating cavity, and improving the temperature rise of the motor. At the same time, the first flange, the second flange and the upper cover are fixed together in one step, simplifying the assembly process.

[0019] In a preferred embodiment, the heating chamber includes a first chamber formed between the bottom wall of the mounting base and the bottom wall of the metal lower cover and a second chamber formed between the side wall of the mounting base and the side wall of the metal lower cover, the first chamber is connected to the second chamber, the heating element is arranged in the first chamber, and the second chamber extends to the side of the motor.

[0020] The heating chamber includes a first chamber and a second chamber. The second chamber realizes the vertical expansion of the heating space, so that the heating element has sufficient heating area during operation, and the slurry is heated more evenly along the axial direction of the cup body, further improving the heating efficiency. At the same time, the second chamber is connected with the air vent to achieve good airflow conduction, and the risk of gas expansion in the heating chamber causing deformation of the metal lower cover is prevented. Since the second chamber extends to the side of the motor, the second chamber forms an air insulation layer isolated between the installation chamber and the slurry in the cup body. The thermal conductivity of air is lower than that of the metal lower cover. Therefore, during the operation of the heating element, more heat of the heating element will be transferred to the cup body through the metal lower cover, reducing the heat transferred to the installation chamber, while improving the slurry heating efficiency and reducing the temperature rise of the motor. In addition, after the heating element stops working, while the installation chamber itself is connected to the outside world to dissipate heat for the motor, the air vent of the heating chamber can be used to connect with the outside world, thereby forming a second heat dissipation channel in the heating chamber to dissipate heat for the motor, the heating element and the head as a whole, and improving the service life of the head.

[0021] In a preferred embodiment, the second chamber is an annular cavity surrounding the outer circumference of the installation cavity, and the annular cavity is arranged around the outer circumference of the motor.

[0022] By setting the second chamber as an annular chamber and surrounding the outer circumference of the motor, the heat in the heating chamber can be transferred outward more evenly along the circumference of the machine head, realizing all-round three-dimensional heating and further improving the heating efficiency. At the same time, an all-round air insulation layer is formed along the circumference of the motor, reducing the heat transfer from all directions of the heating element to the motor, thereby improving the temperature rise of the motor.

[0023] In a preferred embodiment, the mounting seat is offset relative to the metal lower cover.

[0024] Since the motor has a certain radial dimension, the mounting seat needs to have a larger size to accommodate the motor. Therefore, in the case where the metal lower cover is small in size, by offsetting the mounting seat relative to the metal lower cover, the internal space of the metal lower cover can be fully and reasonably utilized radially while the motor is reasonably installed. Even if the motor mounting seat occupies a large space, a heating chamber can still be separated in the lower cover, thereby achieving improved slurry heating efficiency and improved temperature rise of the motor. Offsetting the mounting seat relative to the metal lower cover can help reduce the overall radial dimension of the machine head and achieve reasonable utilization of the internal space of the machine head.

[0025] In a preferred embodiment, the outlet end of the heating element is bent vertically upward and extends into the second chamber.

[0026] By bending the lead end of the heating element vertically upward and extending it into the second chamber, the lead arrangement of the heating element is facilitated and the lead winding is prevented. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In the present utility model, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0041] like Figure 1-4As shown, the utility model provides a soymilk machine in one embodiment, including a cup body 10 and a machine head 20 buckled on the cup body 10, the machine head 20 includes a metal lower cover 21, an upper cover 22 covering the metal lower cover 21, a mounting seat 23 arranged in the metal lower cover 21, a motor 24 and a heating element 25, the mounting seat 23 is provided with a mounting cavity 26, the motor 24 is fixedly installed in the mounting cavity 26, the rotating shaft 241 of the motor 24 passes through the mounting seat 23 and the metal lower cover 21 and extends into the cup body 10 and is connected to a crushing knife 27, a heating cavity 28 for installing the heating element 25 is provided between the mounting seat 23 and the metal lower cover 21, the heating cavity 28 is isolated from the mounting cavity 26 and is not connected to each other, and the upper cover 22 is provided with an air vent 29 connecting the heating cavity 28 with the outside.

[0042] In this embodiment, by providing a mounting cavity 26 in the mounting seat 23, the motor 24 is fixedly installed in the mounting cavity 26, and a heating cavity 28 for installing the heating element 25 is provided between the mounting seat 23 and the metal lower cover 21, so that the heating element 25 and the motor 24 can be installed in two different spaces respectively, and the heating cavity 28 and the mounting cavity 26 are isolated and not connected to each other. Therefore, when the heating element 25 is working, Figure 3 As shown, the heat generated by the heating element 25 is only diffused in the heating chamber 28 and then transferred to the liquid in the cup body 10 through the metal lower cover 21, which can improve the slurry heating efficiency. At the same time, the heat of the heating element 25 will not directly flow into the installation chamber 26 where the motor 24 is installed, thereby isolating the motor 24 from the heat and preventing a large amount of heat from the heating element 25 from being transferred to the motor 24. At the same time, the heating chamber 28 is used to form an air layer to insulate the installation chamber 26 and the high-temperature slurry in the cup body 10, preventing the heat of the high-temperature slurry from being transferred to the motor 24, thereby improving the temperature rise of the motor 24 and extending the service life of the motor 24. In addition, Figure 3 As shown, by setting an air vent 29 connecting the heating chamber 28 with the outside world on the upper cover 22, when the heating element 25 is in working state, the hot air in the heating chamber 28 expands and the air pressure rises. The heating chamber 28 can achieve air pressure balance with the outside world through the air vent 29, thereby preventing safety problems caused by excessive pressure in the heating chamber 28, ensuring safe use, and preventing the metal lower cover 21 from expanding and deforming, ensuring a reliable connection with the upper cover 22, and making the head 20 structure reliable; Figure 4 As shown, when the heating element 25 stops working, the air temperature in the heating chamber 28 drops, and the cold air from the outside enters the heating chamber 28 through the air vents 29 to take away the heat in the heating chamber 28, dissipating the heat of the heating element 25, preventing the machine head 20 from getting too hot or the slurry from sticking to the metal lower cover 21 of the machine head 20, and indirectly taking away the heat of the motor 24 in the heating chamber 28, indirectly dissipating the heat of the motor 24 in the installation chamber 26, thereby extending the service life of the motor 24.

[0043] It should be noted that in the present invention, the sealing isolation method between the heating chamber 28 and the installation chamber 26 can be selected from any one of the following implementation examples 1 or 2:

[0044] Implementation example 1, such as Figure 3 As shown, the upper end of the mounting seat 23 is provided with an opening, the bottom of the upper cover 22 is provided with a first mounting portion 221 and a second mounting portion 222 located radially outside the first mounting portion 221, the upper end of the mounting seat 23 is sealed and docked with the first mounting portion 221 so that the upper cover 22 and the mounting seat 23 enclose a mounting cavity 26, and the upper end of the metal lower cover 21 is fixedly connected with the second mounting portion 222 by screws.

[0045] By setting an opening at the upper end of the mounting seat 23, it is convenient to install the motor 24 into the mounting seat 23, and the assembly is simple. At the same time, the upper end of the mounting seat 23 is sealed and connected with the first mounting part 221 so that the upper cover 22 and the mounting seat 23 are enclosed to form a mounting cavity 26, thereby realizing a sealed isolation between the mounting cavity 26 and the heating cavity 28. The hot air flow in the heating cavity 28 cannot flow into the mounting cavity 26, thereby reducing the heat radiation of the heating element 25 to the motor 24, improving the temperature rise of the motor 24, and using the first mounting part 221 and the second mounting part 222 to limit the mounting seat 23 and the metal lower cover 21 respectively, so that enough space is reserved between the first mounting part 221 and the second mounting part 222 for the heating cavity 28 to directly pass through the outside of the mounting seat 23 and communicate with the air vent 29, without the need to set a separate conducting structure, thereby simplifying the internal structure of the head 20, simplifying the installation of the mounting seat 23, ensuring a stable connection between the mounting seat 23, the metal lower cover 21 and the upper cover 22, and improving the overall structural reliability of the head 20.

[0046] In this implementation example, the fixed position of the mounting seat 23 cannot be selected as any one of the following embodiments 1 or 2:

[0047] In Embodiment 1, a sealing member 223 is provided between the first mounting portion 221 and the mounting seat 23, and the mounting seat 23 is fixedly mounted in the metal lower cover 21. After the metal lower cover 21 is fixedly connected to the second mounting portion 222, the mounting seat 23 and the first mounting portion 221 clamp the sealing member 223;

[0048] In the second embodiment, the first mounting portion 221 is a rib extending downward, the mounting seat 23 is screwed onto the rib and a sealing member 223 is sandwiched between the rib.

[0049] For example, threads are provided on the upper end of the mounting seat 23 and on the surrounding reinforcement, and the mounting seat 23 and the surrounding reinforcement threads cooperate; or, a turn buckle is provided on the upper end of the mounting seat 23, and a buckle position is provided on the surrounding reinforcement, so that the mounting seat 23 and the surrounding reinforcement turn buckle cooperate.

[0050] By providing a sealing member 223 between the first mounting portion 221 and the mounting seat 23, on the one hand, the sealing isolation effect between the mounting cavity 26 and the heating cavity 28 is further improved; on the other hand, after the metal lower cover 21 is fixedly connected to the second mounting portion 222, the mounting seat 23 and the first mounting portion 221 clamp the sealing member 223, which is beneficial for the sealing member 223 to simultaneously play the role of a soft connection between the first mounting portion 221 and the mounting seat 23, thereby preventing the increase of the overall tolerance caused by the cooperation between the metal lower cover 21 and the upper cover 22, and making the assembly and fixation more reliable.

[0051] Implementation Example 2, such as Figure 5 As shown, an opening and a first flange 231 extending outward from the opening are provided at the upper end of the mounting seat 23, and the first flange 231 is sealed and overlapped on the top of the metal lower cover 21 so that the mounting seat 23 and the metal lower cover 21 are enclosed to form a heating chamber 28, and an air guide tube 30 is provided between the upper cover 22 and the mounting seat 23, and an air permeable passage connecting the heating chamber 28 with the air vent 29 is formed inside the air guide tube 30.

[0052] By setting an opening at the upper end of the mounting seat 23 and a first flange 231 extending outward from the opening, the first flange 231 is supported on the top of the metal lower cover 21, and pre-fixation is achieved during the assembly process of the machine head 20, which is convenient for assembly. Then, the mounting seat 23 and the metal lower cover 21 are enclosed to form a heating chamber 28, which improves the sealing and waterproof properties of the heating chamber 28, and achieves a sealed isolation between the mounting chamber 26 and the heating chamber 28. The hot air flow in the heating chamber 28 cannot flow into the mounting chamber 26, thereby reducing the heat radiation of the heating element 25 to the motor 24 and improving the temperature rise of the motor 24. By setting an air guide tube 30 between the upper cover 22 and the mounting seat 23, an air permeable channel is formed inside the air guide tube 30 to connect the heating chamber 28 with the air vent 29, so that the heating chamber 28 can be smoothly connected with the outside world, the air pressure is stable during operation, the metal lower cover 21 is prevented from deformation, and the safety of use is improved.

[0053] In implementation example 2, if Figure 5 As shown, one end of the air guide cylinder 30 is fixed to the upper cover 22 and communicated with the air vent 29, and the other end passes through the mounting seat 23 and extends into the heating chamber 28. Of course, the arrangement of the air guide cylinder can also be: one end of the air guide cylinder 30 is fixed to the mounting seat 23 and communicated with the heating chamber 28, and the other end of the air guide cylinder 30 and the mounting chamber 26 are both communicated with the outside through the air vent 29.

[0054] Whether one end of the air guide tube 30 is directly fixed to the upper cover 22 or fixed to the mounting seat 23, it can achieve smooth conduction between the heating chamber 28 and the outside world, ensuring safety in use. Since the upper cover 22 has a simple structure, the air guide tube 30 is installed on the upper cover 22, which is convenient for production and manufacturing. During the assembly process, the air guide tube 30 is inserted through the mounting seat 23 and extended into the heating chamber 28 to cooperate with the mounting seat 23, and the assembly is simple and reliable; one end of the air guide tube 30 is fixedly installed on the mounting seat 23, and the other end of the air guide tube 30 and the mounting chamber 26 are connected to the outside world through the air vent 29. While achieving heat dissipation of the motor 24, the air vent 29 is shared, and there is no need to set another through hole on the upper cover 22 to dissipate heat from the mounting chamber 26 of the motor 24, and the structure is simple.

[0055] like Figure 5 As shown, in this embodiment, the fixing method of the mounting base 23 can be optionally as follows: a second flange 211 extending outwardly to support the first flange 231 is provided on the top of the metal lower cover 21, a sealing ring is crimped between the first flange 231 and the second flange 211, and the first flange 231, the second flange 211 and the upper cover 22 are fixed together.

[0056] By providing a second flange 211 extending outward on the top of the metal lower cover 21, a larger matching area is provided between the mounting seat 23 and the metal lower cover 21, thereby improving the sealing of the connection position, thereby ensuring the isolation effect between the mounting cavity 26 and the heating cavity 28, and improving the temperature rise of the motor 24. At the same time, the first flange 231, the second flange 211 and the upper cover 22 are fixed together in one step, thereby simplifying the assembly process.

[0057] It should be noted that the present invention does not limit the shape of the heating chamber 28. In the implementation example 1, Figure 1-4 As shown, the heating chamber 28 includes a first chamber 281 formed between the bottom wall of the mounting base 23 and the bottom wall of the metal lower cover 21 and a second chamber 282 formed between the side wall of the mounting base 23 and the side wall of the metal lower cover 21. The first chamber 281 is connected to the second chamber 282, the heating element 25 is arranged in the first chamber 281, and the second chamber 282 extends to the side of the motor 24.

[0058] Specifically, the second chamber 282 is an annular cavity surrounding the outer periphery of the mounting cavity 26 , and the annular cavity is arranged around the outer periphery of the motor 24 .

[0059] By setting the second chamber 282 as an annular cavity and surrounding the outer periphery of the motor 24, the heat of the heating cavity 28 can be transferred outward more evenly along the circumference of the head 20, realizing all-round three-dimensional heating and further improving the heating efficiency. At the same time, an all-round air insulation layer is formed along the circumference of the motor 24, reducing the heat transfer from all directions of the heating element 25 to the motor 24, thereby improving the temperature rise of the motor 24.

[0060] The heating chamber 28 includes a first chamber 281 and a second chamber 282. The second chamber 282 realizes the vertical expansion of the heating space, so that the heating element 25 has a sufficient heating area during operation. Figure 3 As shown, the slurry is heated more evenly along the axial direction of the cup body 10, further improving the heating efficiency. At the same time, the second chamber 282 is connected to the air vent 29 to achieve good airflow conduction, thereby preventing the risk of gas expansion in the heating chamber 28 causing deformation of the metal lower cover 21. Since the second chamber 282 extends to the side of the motor 24, the second chamber 282 forms an air insulation layer that isolates the installation chamber 26 from the slurry in the cup body 10. The thermal conductivity of air is lower than that of the metal lower cover 21. Therefore, during the operation of the heating element 25, more heat from the heating element 25 will be transferred to the cup body 10 through the metal lower cover 21, reducing the heat transferred to the installation chamber 26, thereby improving the slurry heating efficiency and reducing the temperature rise of the motor 24. In addition, after the heating element 25 stops working, as shown in FIG. Figure 4 As shown, while the installation cavity 26 itself is connected to the outside world to dissipate heat for the motor 24, the air vent 29 of the heating cavity 28 can be used to connect to the outside world, thereby forming a second heat dissipation channel in the heating cavity 28 to achieve heat dissipation for the motor 24, the heating element 25 and the head 20 as a whole, thereby increasing the service life of the head 20.

[0061] Preferably, the outlet end of the heating element 25 is bent vertically upward and extends into the second chamber 282 .

[0062] By bending the lead end of the heating element 25 vertically upward and extending it into the second chamber 282, the lead arrangement of the heating element 25 is facilitated and the lead winding is prevented.

[0063] Of course, in another embodiment, the mounting seat 23 is offset relative to the metal lower cover 21, so that the heating chamber 28 includes a first chamber 281 and a second chamber 282, and the second chamber 282 realizes the vertical expansion of the heating space. Specifically, there is a space between one side of the mounting seat 23 and the metal lower cover 21 to form the second chamber 282, and the other side is in contact with the metal lower cover 21, or the second chamber 282 in the heating chamber 28 is an annular chamber, and the radial width of the annular chamber on both sides of the mounting seat 23 is different.

[0064] Since the motor 24 has a certain radial dimension, the mounting seat 23 needs to have a larger size to accommodate the motor 24. Therefore, in the case where the metal lower cover 21 is small in size, by offsetting the mounting seat 23 relative to the metal lower cover 21, the motor 24 can be reasonably installed while the radial internal space of the metal lower cover 21 is fully and reasonably utilized. Even if the mounting seat 23 of the motor 24 occupies a large space, the heating chamber 28 can still be separated in the lower cover, thereby achieving improved slurry heating efficiency and improved temperature rise of the motor 24. Offsetting the mounting seat 23 relative to the metal lower cover 21 can help reduce the overall radial dimension of the head 20 and achieve reasonable utilization of the internal space of the head 20.
