Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a small-sized food processing machine. Background Technology

[0002] Existing food processors, such as soy milk makers, blenders, or food processors that do not require hand washing, typically prepare hot soy milk. After the food processor finishes making the soy milk, users need to pour out the hot liquid and wait for it to cool before drinking it, which takes a long time and affects the user experience.

[0003] The applicant previously disclosed a food processing machine in a patent application with publication number CN110876570A. The machine uses a cooling device installed between the shell and the mixing cup to cool the outer wall of the inner cup above the water level indicator. The cooling device includes a fan mounted on the shell and blowing air onto the outer wall of the inner cup for cooling.

[0004] The above solution primarily utilizes a fan to cool and eliminate the foam at the top, preventing spillage. While the fan does dissipate heat from the soy milk, it mainly blows air onto the cup above the water level indicator, resulting in localized cooling and a slow cooling rate for the soy milk inside. Furthermore, the space between the outer shell and the mixing cup houses multiple components such as heating elements and controls. While the fan is cooling the mixing cup, the airflow encounters significant obstruction as it passes through these components, further slowing down airflow within the space. This results in poor heat dissipation for the mixing cup, leaving a long waiting time before the soy milk can be consumed. Additionally, the fan's placement between the outer shell and the mixing cup increases the outer diameter of the shell, making it bulky and inconvenient for users to handle.

[0005] In addition, some existing pressure food processors maintain high pressure inside the cup to cook soy milk and improve its smooth texture. During the soy milk making process, these food processors may cause excessive pressure inside the cup, resulting in overflow or the lid bulging, posing a safety hazard. Therefore, these pressure food processors also need a cooling structure that can quickly cool down to reduce the pressure inside the cup. Utility Model Content

[0006] This invention provides a small-volume food processing machine that solves the problem of how to reasonably arrange the fan within a limited outer shell space, so as to solve the problem of faster heat dissipation of the cup body without increasing the overall size of the machine to make it convenient for users to handle.

[0007] The technical solution adopted in this utility model is as follows:

[0008] This utility model provides a small-volume food processor, including a cup body, a shell that seals with the cup body, a motor disposed inside the shell and located below the cup body, and a handle located on the side of the cup body. A crushing device is disposed inside the cup body, and the rotating shaft of the motor passes through the bottom wall of the cup body and is connected to the crushing device for transmission. The shell has an air inlet and an air outlet located below the cup body. A first fan is disposed at the air inlet to draw outside air into the shell body, and a second fan is disposed at the air outlet to draw air out of the shell body to the outside. Both the first fan and the second fan are disposed facing the cup body.

[0009] This utility model provides a small-sized food processor. The outer shell has an air inlet and an air outlet located below the cup. The air inlet is equipped with a first fan that draws outside air into the outer shell, and the air outlet is equipped with a second fan that draws air out of the outer shell to the outside. This allows the first and second fans to be installed in the space below the cup. The first and second fans can share the radial space of the cup, avoiding increasing the radial dimension of the food processor and making the food processor compact. This also avoids the difficulty of users picking up and putting down the food processor by holding the handle, making it more convenient and labor-saving to use. Under this premise, both the first and second fans are oriented towards the cup body. When the first and second fans are working, cold air from the outside enters through the air inlet, directly exchanges heat with the cup body, and then exits through the air outlet. The first fan then replenishes the outer shell with cold air, thereby achieving airflow circulation and cooling of the cup body. Since the first and second fans are located at the air inlet and air outlet respectively, they work together to provide power for airflow circulation, accelerate the airflow speed within the outer shell, thereby improving heat exchange efficiency, enhancing the cup body's heat dissipation efficiency, accelerating the cooling of the cup body and the liquid inside, reducing the waiting time for the user to drink, and improving the user experience.

[0010] In addition, because the cup cools down faster, for food processors that require pressure cooking, the first and second fans can be activated to quickly cool the cup after the pressure holding period, achieving the purpose of rapid pressure release without the need to release hot steam, making it safe to use.

[0011] In a preferred embodiment, both the first fan and the second fan are located below the motor and are arranged laterally toward the bottom wall of the cup.

[0012] By horizontally positioning the first and second fans, airflow can be directed directly to the bottom wall of the cup, further accelerating the cooling process. By placing both fans horizontally below the motor and towards the bottom wall of the cup, they can be partially stacked below the motor, further reducing the radial dimension of the fan arrangement. This reduces the radial dimension of the lower part of the casing, specifically the radial dimension surrounding the motor. The overall dimensions are uniform from top to bottom, making it convenient for users to handle and saving kitchen space.

[0013] More preferably, both the air inlet and the air outlet are located on the bottom wall of the housing, with the first fan facing the air inlet and the second fan facing the air outlet.

[0014] Alternatively, the housing may include a bottom wall, side walls, and an arc-shaped transition wall connecting the bottom wall and side walls, with both the air inlet and air outlet located on the transition wall.

[0015] By opening both the air inlet and the air outlet on the bottom wall of the outer casing, with the first fan facing the air inlet and the second fan facing the air outlet, the airflow driven by the first fan blows vertically upwards directly onto the cup body. Similarly, the airflow driven by the second fan vertically carries away the heat from the cup body. The airflow is smooth and does not need to change its direction, thereby reducing airflow loss, improving heat dissipation efficiency, and accelerating the cooling speed of the cup body and the liquid inside.

[0016] Of course, whether the air inlet and outlet are located on the transition wall or the bottom wall of the outer shell, the horizontal arrangement of the first and second fans allows the airflow to blow directly onto the bottom wall of the cup, further accelerating the cooling speed of the cup.

[0017] In addition, the air inlet and outlet are both located on the transition wall, which can prevent water and debris on the workbench from being sucked into the housing through the air inlet. This avoids water entering the housing and damaging electrical components such as motors, thus extending their service life. It also prevents debris from entering the housing and interfering with airflow circulation, ensuring heat dissipation.

[0018] In a preferred embodiment, both the first fan and the second fan are inclinedly arranged above the motor, the air inlet is opened on the side wall of the housing and adjacent to the first fan, and the air outlet is opened on the side wall of the housing and adjacent to the second fan.

[0019] Alternatively, both the first fan and the second fan are inclinedly arranged below the motor, and the air inlet and air outlet are opened on the bottom wall of the housing;

[0020] Alternatively, both the first and second fans are inclinedly arranged below the motor. The housing includes a bottom wall, side walls, and an arc-shaped transition wall connecting the bottom wall and side walls. The air inlet and air outlet are both opened on the transition wall. The first fan is directly opposite the air inlet, and the second fan is directly opposite the air outlet.

[0021] By tilting both the first and second fans, whether above or below the motor, it is possible to increase the size of a single fan to improve the airflow area without increasing its radial space occupied in the housing after installation. This results in high space utilization, thereby increasing airflow to accelerate cup cooling while simultaneously achieving space compactness and minimizing the overall size of the machine.

[0022] When the first fan and the air inlet are directly opposite each other, and the second fan and the air outlet are directly opposite each other, the smoothness of airflow is improved, airflow loss is reduced, and the heat dissipation speed is increased.

[0023] In a preferred embodiment, the housing is provided with a motor cover that surrounds the motor. The motor cover is integrally formed with a first bracket near the air inlet and a second bracket near the air outlet. The first fan and the second fan are respectively fixed on the first bracket and the second bracket.

[0024] Preferably, the motor cover includes a first cover and a second cover that are separately disposed, the first cover and the second cover are docked and fixed to surround the motor, the first bracket is integrally formed on the first cover, and the second bracket is integrally formed on the second cover.

[0025] By incorporating a motor cover, the motor can be enclosed and isolated, preventing motor dust from splashing or obstructing airflow, and reducing the impact of motor heat on the cup's cooling system. The motor can be independently cooled by a dedicated cooling fan, ensuring effective heat dissipation for the cup. The motor cover is integrally formed with a first bracket near the air inlet and a second bracket near the air outlet. The first and second fans are respectively fixed to the first and second brackets. This further integrates the fan mounting brackets with the motor cover, resulting in a compact structure and easy installation.

[0026] The motor cover includes a first cover and a second cover that are separately configured. The first cover and the second cover are docked and fixed to surround the motor, which realizes the simple installation of the first cover and the second cover with the motor and the high assembly efficiency. At the same time, the first fan can be fixed to the first bracket to form an installation module, and the second fan is fixed to the second bracket to form a module. After the first cover and the second cover are fixed, the first fan and the second fan are fixedly installed, which improves the assembly efficiency.

[0027] In a preferred embodiment, a motor bracket is provided between the motor and the cup body. The motor bracket has a first extension extending toward the air inlet and a second extension extending toward the air outlet. The first fan and the second fan are respectively fixed to the first extension or the second extension.

[0028] By setting up a motor bracket, the motor is fixedly installed to the cup body. At the same time, the motor bracket is integrated with a first extension and a second extension, thereby realizing the integrated installation of the first fan and the second fan. The structure is compact, the space is used reasonably, and the whole machine is miniaturized.

[0029] In a preferred embodiment, the housing is provided with a plurality of upwardly extending air intake plates, which divide the inner cavity of the housing into an air intake duct and an air outlet duct, and the first fan and the second fan are respectively disposed in the air intake duct and the air outlet duct.

[0030] By setting up air intake plates, multiple air intake plates divide the inner cavity of the outer casing into air intake ducts and air exhaust ducts, so that the airflow drawn in by the first fan and the airflow drawn out by the second fan do not interfere with each other, thereby improving airflow efficiency, reducing airflow loss, and improving heat dissipation efficiency.

[0031] In a preferred embodiment, the upper part of the cup body is exposed from the outer shell, the top end of the outer shell is sealed and fitted to the bottom of the side wall of the cup body, the upper end of the handle is fixedly connected to the upper part of the cup body, the bottom wall of the cup body, the outer peripheral wall of the motor and the outer shell together form a cooling cavity, and the first fan and the second fan are both disposed in the cooling cavity.

[0032] In a preferred embodiment, the top of the cup body is provided with an outwardly extending flange, a sealing ring is fitted under the flange, the top of the outer shell extends to press against the sealing ring, the handle is fixedly connected to the outer shell, an extension cavity is formed between the side wall of the cup body and the outer shell, a cooling cavity communicating with the extension cavity is formed between the bottom wall of the cup body, the outer peripheral wall of the motor and the outer shell, and both the first fan and the second fan are disposed in the cooling cavity.

[0033] Whether the outer shell is sealed to the bottom of the side wall of the cup or extends to the flange of the cup to press the sealing ring, the outer shell and the cup body are sealed together, so that a closed chamber is formed between the cup body and the outer shell. The airflow driven by the first fan and the second fan can circulate in the closed chamber to achieve rapid heat dissipation of the cup body.

[0034] By sealing the top of the outer shell to the bottom of the side wall of the cup body, the cup body is partially exposed, improving visibility and enhancing the user experience. By extending the top of the outer shell to press against the sealing ring and abutting against the flange of the cup body, an extended cavity is formed between the side wall of the cup body and the outer shell. The airflow driven by the first and second fans can flow into the extended cavity to dissipate heat from the outer peripheral wall of the cup body, increasing the contact area between the airflow and the cup body and improving heat dissipation efficiency.

[0035] In a preferred embodiment, the cup body is covered with a cup lid, and the cup body and the cup lid together form a sealed pulping chamber. A pressure relief hole and a pressure relief valve installed at the pressure relief hole are provided through the cup lid.

[0036] By incorporating a pressure relief valve, the pressure inside the cup is released when the preset pressure is reached, ensuring safe use and enabling pressure slurry making, thus improving the smooth texture of the soy milk. Furthermore, the presence of a first and second fan allows for flexible control during the slurry making process to provide initial cooling and pressure relief to the cup. If the pressure remains too high, the pressure relief valve opens, providing a second layer of pressure relief protection.

[0037] In a preferred embodiment, the food processing machine further includes a control device installed in the housing and a detection device connected to the control device and extending into the cup body. The detection device is used to detect the air pressure signal inside the cup body, and the control device controls the start and stop of the first fan and the second fan according to the air pressure signal detected by the detection device.

[0038] By setting up control and detection devices, the first and second fans can be controlled by the control device and respond quickly according to the air pressure signal in the pulping chamber. At the same time, since the detection device can detect the pressure in the pulping chamber in real time, the fans can be started according to the actual pressure to adjust the pressure in the pulping chamber throughout the pulping stage of the food processing machine, instead of having to wait for the pressure to reach the preset value as with the traditional pressure relief valve, which is usually opened for pressure relief adjustment after pulping is completed. Therefore, the timing of pressure adjustment is more flexible, timely and accurate. Attached Figure Description

[0046] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0047] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0050] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0051] like Figure 1 As shown, in one embodiment of this utility model, a small-volume food processor is provided, including a cup body 10, a housing 30 that is sealed to the cup body 10, a motor 40 disposed inside the housing 30 and located below the cup body 10, and a handle 50 located on the side of the cup body 10. A crushing device 11 is disposed inside the cup body 10. The rotating shaft of the motor 40 passes through the bottom wall of the cup body 10 and is connected to the crushing device 11 for transmission. The housing 30 has an air inlet 31 and an air outlet 32 ​​located below the cup body 10. A first fan 61 is disposed at the air inlet 31 to draw outside air into the housing 30, and a second fan 62 is disposed at the air outlet 32 ​​to draw air out of the housing 30 to the outside. Both the first fan 61 and the second fan 62 are disposed facing the cup body 10.

[0052] The small-sized food processor provided by this utility model has an air inlet 31 and an air outlet 32 ​​located below the cup body 10 in the outer casing 30. The air inlet 31 is equipped with a first fan 61 that draws outside air into the outer casing 30, and the air outlet 32 ​​is equipped with a second fan 62 that draws air out of the outer casing 30 to the outside. This allows the first fan 61 and the second fan 62 to be installed in the space of the outer casing 30 below the cup body 10. The first fan 61 and the second fan 62 can share the radial space of the cup body 10, avoiding the need to increase the radial dimension of the food processor, thus achieving a compact size. This avoids the need for users to exert effort when handling the food processor. Users can easily pick up and put down the food processor by holding the handle 50, making it more convenient and labor-saving to use. Under this premise, both the first fan 61 and the second fan 62 are positioned facing the cup body 10. When the first fan 61 and the second fan 62 are working, cold air from the outside enters through the air inlet 31, directly exchanges heat with the cup body 10, and then exits through the air outlet 32. The first fan 61 then replenishes the cold air into the outer shell 30, thereby achieving airflow circulation to achieve circulating heat dissipation of the cup body 10. Since the first fan 61 and the second fan 62 are located at the air inlet 31 and the air outlet 32 ​​respectively, they together provide power for the airflow circulation, accelerate the airflow speed in the outer shell 30, thereby improving heat exchange efficiency, improving the heat dissipation efficiency of the cup body 10, accelerating the cooling of the cup body 10 and the liquid inside the cup, reducing the waiting time required for the user to drink, and improving the user experience.

[0053] In addition, because the cup body 10 cools down faster, for food processors that require pressure cooking, the cup body 10 can be quickly cooled down by starting the first fan 61 and the second fan 62 after the pressure holding is completed, so as to achieve the purpose of rapid pressure release without the need to release hot steam, making it safe to use.

[0054] like Figure 1 As shown, in a preferred embodiment, the cup body 10 is covered with a cup lid 20, and the cup body 10 and the cup lid 20 together form a sealed pulping chamber. A heating tube 12 is fixed on the outside of the cup body, and a pressure relief hole and a pressure relief valve 21 installed at the pressure relief hole are provided through the cup lid 20.

[0055] By setting a pressure relief valve 21, the pressure inside the cup body 10 is released when the preset pressure is reached, ensuring safe use and enabling pressure slurry making, thus improving the smooth texture of the soy milk. Furthermore, due to the presence of a first fan 61 and a second fan 62, the first and second fans can be flexibly controlled during the slurry making process to provide initial cooling and pressure relief to the cup body 10. If the pressure remains too high, the pressure relief valve 21 opens to release pressure, achieving a second layer of pressure relief protection.

[0056] like Figure 1As shown, in a preferred embodiment, the food processor further includes a control device 90 installed within the housing 30 and a detection device 80 connected to the control device and extending into the cup body 10. The detection device is used to detect the air pressure signal within the cup body 10, and the control device controls the start and stop of the first fan 61 and the second fan 62 based on the air pressure signal detected by the detection device. Figure 1 As shown, the detection device is a temperature sensor, which indirectly detects the air pressure signal by detecting the temperature inside the cup. In fact, the detection device can also be a pressure sensor.

[0057] By setting up control and detection devices, the first fan 61 and the second fan 62 can be controlled by the control device and respond quickly according to the air pressure signal in the pulping chamber. At the same time, since the detection device can detect the pressure in the pulping chamber in real time, the fans can be started according to the actual pressure to adjust the pressure in the pulping chamber throughout the pulping stage of the food processing machine, instead of having to wait for the pressure to reach the preset value as in the traditional pressure relief valve 21, which is usually opened for pressure relief adjustment after pulping is completed. Therefore, the timing of pressure adjustment is more flexible, timely and accurate.

[0058] It should be noted that this utility model does not limit the arrangement of the first fan 61 and the second fan 62. For example, any one of the following embodiments 1-6 can be used:

[0059] Implementation Example 1, such as Figure 1-5 As shown, the first fan 61 and the second fan 62 are both located below the motor 40 and are arranged horizontally toward the bottom wall of the cup body 10.

[0060] By horizontally positioning the first fan 61 and the second fan 62, airflow can be directed directly to the bottom wall of the cup body 10, further accelerating the cooling speed of the cup body 10. By placing both the first fan 61 and the second fan 62 horizontally below the motor 40 and towards the bottom wall of the cup body 10, the first fan 61 and the second fan 62 can be partially stacked below the motor 40, further reducing the radial dimension of the first fan 61 and the second fan 62 after they are arranged, thereby reducing the radial dimension of the lower part of the outer casing 30, i.e., the radial dimension of the part of the outer casing 30 surrounding the motor 40. The overall appearance of the machine is uniform in size from top to bottom, making it convenient for users to handle and reducing the space occupied in the kitchen.

[0061] Preferably, such as Figure 1 , 4 As shown, both the air inlet 31 and the air outlet 32 ​​are located on the bottom wall of the outer casing 30. The first fan 61 is directly opposite the air inlet 31, and the second fan 62 is directly opposite the air outlet 32.

[0062] More preferably, an upwardly arched step is provided on the bottom wall of the outer casing 30, and the air inlet 31 and the air outlet 32 ​​are provided on the step to prevent water from the work surface from entering the outer casing.

[0063] In this embodiment, both the air inlet 31 and the air outlet 32 ​​are located on the bottom wall of the outer casing 30. The first fan 61 is directly opposite the air inlet 31, and the second fan 62 is directly opposite the air outlet 32. This allows the airflow driven by the first fan 61 to blow vertically upwards directly onto the cup body 10. Similarly, the airflow driven by the second fan 62 vertically carries away the heat from the cup body 10. The airflow is smooth and does not need to change its direction, thereby reducing airflow loss, improving heat dissipation efficiency, and accelerating the cooling rate of the cup body 10 and the liquid inside the cup.

[0064] This utility model does not limit the fixing method of the first fan 61 and the second fan 62. In this embodiment, for example... Figure 1 As shown, a motor cover 41 surrounding the motor 40 is provided inside the outer casing 30, combined with... Figure 2 , 3 As shown, the motor cover 41 is integrally formed with a first bracket 413 near the air inlet 31 and a second bracket 414 near the air outlet 32. The first fan 61 and the second fan 62 are respectively fixed to the first bracket 413 and the second bracket 414 by screws 63.

[0065] Combination Figure 2 , 3 As shown, preferably, the motor cover 41 includes a first cover 411 and a second cover 412 that are separately disposed. The first cover 411 and the second cover 412 are mated and fixed to surround the motor 40. A first bracket 413 is integrally formed on the first cover 411, and a second bracket 414 is integrally formed on the second cover 412. The first cover 411 and the second cover 412 can be fixed by snap-fit ​​or screws.

[0066] By providing a motor cover 41, the motor cover 41 can surround and isolate the motor 40. On the one hand, it prevents the carbon powder from the motor 40 from splashing indiscriminately or obstructing airflow. On the other hand, it reduces the impact of the heat from the motor 40 on the heat dissipation of the cup body 10. The motor 40 can be independently equipped with a cooling fan for heat dissipation, ensuring the heat dissipation effect of the cup body 10. The motor cover 41 is integrally formed with a first bracket 413 near the air inlet 31 and a second bracket 414 near the air outlet 32. The first fan 61 and the second fan 62 are respectively fixed to the first bracket 413 and the second bracket 414. This further integrates the fan mounting bracket with the motor cover 41, resulting in a compact structure and easy installation.

[0067] The motor cover 41 includes a first cover 411 and a second cover 412 that are separately arranged. The first cover 411 and the second cover 412 are connected to surround the motor 40, so as to realize the simple installation of the first cover 411 and the second cover 412 with the motor 40 and the high assembly efficiency. At the same time, the first fan 61 can be fixed by the first bracket 413 to form an installation module, and the second fan 62 is fixed by the second bracket 414 to form a module. After the first cover 411 and the second cover 412 are fixed, the first fan 61 and the second fan 62 are fixedly installed, which improves the assembly efficiency.

[0068] Of course, in other embodiments, preferably, a motor bracket is provided between the motor 40 and the cup body 10. The motor bracket has a first extension extending toward the air inlet 31 and a second extension extending toward the air outlet 32. The first fan 61 and the second fan 62 are respectively fixed on the first extension or the second extension.

[0069] By setting a motor bracket, the motor 40 is fixedly installed with the cup body 10. At the same time, the motor bracket is integrally provided with a first extension and a second extension, thereby realizing the integrated installation of the first fan 61 and the second fan 62. The structure is compact, the space is used reasonably, and the whole machine is miniaturized.

[0070] It is understood that the above-described fixing method for the first and second fans can also be applied to other embodiments of this utility model.

[0071] In addition, as a preferred option, such as Figure 2 , 5 As shown, the housing 30 has multiple upward-extending air intake plates 70 inside. The air intake plates can be set on the base of the housing or on the inner side wall of the housing. The multiple air intake plates 70 divide the inner cavity of the housing 30 into an air inlet duct and an air outlet duct. The first fan 61 and the second fan 62 are respectively set in the air inlet duct and the air outlet duct.

[0072] like Figure 2 As shown, preferably, the air intake plate divides the inner cavity of the outer casing 30 into an air inlet duct, an air outlet duct, and a heat dissipation channel for accommodating the control device.

[0073] By setting up air intake plates 70, multiple air intake plates 70 divide the inner cavity of the outer shell 30 into an air intake duct and an air outlet duct, so that the airflow drawn in by the first fan 61 and the airflow drawn out by the second fan 62 do not interfere with each other, thereby improving the airflow efficiency, reducing airflow loss, and improving heat dissipation efficiency.

[0074] like Figure 1As shown in this embodiment, the top of the cup body 10 is provided with an outwardly extending flange 13, and a sealing ring 14 is fitted under the flange 13. The top of the outer shell 30 extends to the flange 13 to press the sealing ring 14. The handle 50 is fixedly connected to the outer shell 30. An extension cavity 35 is formed between the side wall of the cup body 10 and the outer shell 30. A cooling cavity 34 communicating with the extension cavity 35 is formed between the bottom wall of the cup body 10, the outer peripheral wall of the motor 40 and the outer shell 30. The first fan 61 and the second fan 62 are both arranged in the cooling cavity 34.

[0075] Of course, in other embodiments of this utility model, optionally, the upper part of the cup body 10 is exposed from the outer shell 30, the top end of the outer shell 30 is sealed and fitted to the bottom of the side wall of the cup body 10, the upper end of the handle 50 is fixedly connected to the upper part of the cup body 10, the bottom wall of the cup body 10, the outer peripheral wall of the motor 40 and the outer shell 30 together form a cooling cavity 34, and the first fan 61 and the second fan 62 are both arranged in the cooling cavity 34.

[0076] It is understandable that whether the outer shell 30 is sealed and fitted onto the bottom of the side wall of the cup body 10 or extends to the flange of the cup body 10 to press the sealing ring, the outer shell 30 and the cup body 10 are sealed together, so that a closed chamber is formed between the cup body 10 and the outer shell 30. The airflow driven by the first fan 61 and the second fan 62 can circulate in the closed chamber to achieve rapid heat dissipation of the cup body 10.

[0077] By sealing the top of the outer shell 30 to the bottom of the side wall of the cup body 10, the cup body 10 is partially exposed, improving visibility and enhancing the user experience. By extending the top of the outer shell 30 to press the sealing ring and abutting against the flange of the cup body 10, an extension cavity 35 is formed between the side wall of the cup body 10 and the outer shell 30. The airflow driven by the first fan 61 and the second fan 62 can flow into the extension cavity 35 to dissipate heat from the outer peripheral wall of the cup body 10, increasing the contact area between the airflow and the cup body 10 and improving heat dissipation efficiency.

[0078] In Implementation Example 2, both the first fan 61 and the second fan 62 are located below the motor 40 and are arranged laterally toward the bottom wall of the cup body 10. Unlike Implementation Example 1, the outer casing 30 includes a bottom wall, a side wall, and an arc-shaped transition wall 33 connecting the bottom wall and the side wall. The air inlet 31 and the air outlet 32 ​​are both opened in the transition wall 33.

[0079] Of course, whether the air inlet 31 and the air outlet 32 ​​are located on the transition wall 33 or the bottom wall of the outer shell 30, the horizontal arrangement of the first fan 61 and the second fan 62 allows the airflow to blow directly onto the bottom wall of the cup body 10, further accelerating the cooling speed of the cup body 10.

[0080] In addition, in this embodiment, both the air inlet 31 and the air outlet 32 ​​are located on the transition wall 33, which can prevent water and debris on the workbench from being sucked into the housing 30 through the air inlet 31, avoid water entering the housing 30 and damaging electrical components such as the motor 40, and extend service life. It also prevents debris from entering the housing 30 and interfering with airflow circulation, thus ensuring heat dissipation.

[0081] In Implementation Example 3, both the first fan 61 and the second fan 62 are located above the motor 40. In this implementation example, the drive shaft driven by the motor protrudes from above the motor and extends to reserve sufficient space between the motor 40 and the cup body 10. The first fan 61 and the second fan 62 are located between the cup body 10 and the motor 40 and are arranged laterally toward the bottom wall of the cup body 10.

[0082] Preferably, the housing is provided with an inwardly extending air inlet near the first fan and an air outlet near the second fan, with the air inlet and air outlet located in the air inlet and air outlet respectively.

[0083] In Example 4, the first fan 61 and the second fan 62 are both inclined and positioned above the motor 40. The air inlet 31 is located on the side wall of the housing 30 and is adjacent to the first fan 61, and the air outlet 32 ​​is located on the side wall of the housing 30 and is adjacent to the second fan 62.

[0084] Of course, as a preferred option, the air inlet can be placed on one side of the handle to cool the handle and prevent users from getting their hands burned when they pick it up.

[0085] In Example 5, the first fan 61 and the second fan 62 are both inclinedly arranged below the motor 40, and the air inlet 31 and the air outlet 32 ​​are opened on the bottom wall of the housing 30.

[0086] In Example 6, the first fan 61 and the second fan 62 are both inclinedly arranged below the motor 40. The housing 30 includes a bottom wall, a side wall, and an arc-shaped transition wall 33 connecting the bottom wall and the side wall. The air inlet 31 and the air outlet 32 ​​are both opened on the transition wall 33. The first fan 61 is directly opposite the air inlet 31, and the second fan 62 is directly opposite the air outlet 32.

[0087] It should be noted that in implementation examples 4, 5, and 6, by tilting both the first fan 61 and the second fan 62, whether above or below the motor 40, it is possible to increase the radial space occupied by each fan in the housing 30 without increasing the airflow area. This results in high space utilization, thereby increasing airflow to accelerate the cooling of the cup 10 while simultaneously achieving a compact design and a smaller overall size. When the first fan 61 is directly opposite the air inlet 31 and the second fan 62 is directly opposite the air outlet 32, airflow smoothness is improved, airflow loss is reduced, and heat dissipation speed is increased.
