Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a food processor with good heat dissipation effect. Background Art

[0002] Existing food processors generally include a main body and a cup assembly detachably arranged on the main body. The cup assembly includes a cup, a motor arranged below the cup, and a cup base fixedly connected to the bottom of the cup. When a user uses the food processor, food materials are put into the cup, and the motor drives a crushing device to rotate at a high speed to realize the processing of the food materials. At present, most food processors use series-wound motors. During the high-speed rotation of the series-wound motor, a relatively high amount of heat will be generated. In order to dissipate the heat of the motor, for example, Chinese Utility Model Patent CN209712650U discloses a wall-breaking cooking machine provided with an air inlet pipe. A blower is arranged in the main body, and the blower is used to make indoor air enter the main body from the indoor air inlet of the base, and then enter the cup base through the air inlet pipe to dissipate the heat of the motor. After the air flow passes through the motor, it enters the main body through the air outlet holes of the air guide plate and is discharged through the main body. In addition to the above solutions, the applicant has also developed a food processor using a brushless motor. By replacing the series-wound motor with a brushless motor, not only can the noise during operation be reduced, but also the temperature rise of the motor can be reduced. In order to control components such as the brushless motor, a power supply board for controlling the operation of components such as the brushless motor is necessarily provided in the food processor. The working temperature of the electronic devices on the power supply board directly determines their service life and stability. During the working process, the power supply board will generate a certain amount of heat, especially the IPM module cooperating with the brushless motor will generate a relatively high amount of heat. If the above heat dissipation method is adopted and the brushless motor and the power supply board are arranged in the same heat dissipation channel, it will cause the heat dissipated by the brushless motor to heat the air flow in the heat dissipation channel, resulting in a reduction in the temperature difference between the heated air flow and the power supply board, and further causing a poor heat dissipation effect of the power supply board. The continuous temperature rise of the power supply board will cause the devices on the power supply board to fail due to overheating, thereby affecting the performance of the food processor and reducing its working reliability. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a food processor with good heat dissipation effect, so as to solve the problem that the power supply board and the brushless motor in the existing food processor are located in the same heat dissipation channel, resulting in mutual interference in heat dissipation between the two, and the low heat dissipation efficiency causes the power supply board and the brushless motor to easily overheat and fail.

[0004] To achieve the above object, the utility model provides a food processor with good heat dissipation effect, which includes a main body and a cup assembly detachably arranged on the main body. The cup assembly includes a cup body, a brushless motor arranged below the cup body, and a cup base fixedly connected to the bottom of the cup body. The cup base and the cup body enclose an installation cavity for accommodating the brushless motor. The main body includes a main body housing formed with an accommodation cavity, and a power board cooperating with the brushless motor is arranged in the accommodation cavity. A first heat dissipation channel communicating with the outside and dissipating heat from the brushless motor is formed in the installation cavity, and a second heat dissipation channel communicating with the outside and dissipating heat from the power board is formed in the accommodation cavity. The first heat dissipation channel and the second heat dissipation channel are not communicated with each other.

[0005] In this application, by using a brushless motor and relying on the characteristics of the brushless motor, when the user uses the food processor to process food materials, the noise generated by the rotation of the motor is lower, achieving the effect of noise reduction. At the same time, the brushless motor can achieve frequency conversion control, enabling the food processor to control the brushless motor to output different speeds according to different food materials and processing processes, which can make the processing effect of the food materials better and the processing more sufficient, improving the output taste of the food materials. Moreover, the brushless motor occupies less space, which helps to improve the compactness of the internal structure of the whole machine, reduce the occupied space of the food processor, and facilitate the user to store it.

[0006] At the same time, a first heat dissipation channel communicating with the outside and dissipating heat from the brushless motor is formed in the installation cavity, and a second heat dissipation channel communicating with the outside and dissipating heat from the power board is formed in the accommodation cavity, enabling the brushless motor and the power board to dissipate heat respectively in the first heat dissipation channel and the second heat dissipation channel, effectively reducing the temperature rise of the brushless motor and the power board, avoiding the situation that the obvious temperature rise of the brushless motor and the power board leads to accelerated aging, greatly improving the heat dissipation effect and reliability of the power board and the brushless motor, helping to extend the service life of the brushless motor and the power board, and ensuring its working stability.

[0007] At the same time, the first heat dissipation channel and the second heat dissipation channel are not communicated with each other, so that the air flow entering the first heat dissipation channel can only dissipate heat from the brushless motor, and the air flow entering the second heat dissipation channel can only dissipate heat from the power board. The heat dissipation processes do not interfere with each other, avoiding the situation that the air flow after dissipating heat from the brushless motor dissipates heat from the power board again due to the connection of the first heat dissipation channel and the second heat dissipation channel, resulting in a smaller temperature difference between the subsequent air flow passing through the power board and the power board or even the temperature of the air flow being higher than the temperature of the power board, causing a poor heat dissipation effect or even a temperature rise of the power board. It can effectively improve the heat dissipation efficiency, and the air flow can quickly discharge outward after passing through the brushless motor and the power board, improving the flow rate of the air flow in the first heat dissipation channel and the second heat dissipation channel, and further improving the air flow rate passing through the brushless motor and the power board per unit time, thereby further enhancing the heat dissipation efficiency.

[0008] In a preferred implementation of a food processor with good heat dissipation, the brushless motor includes a motor housing and a motor body disposed inside the motor housing. The first heat dissipation channel includes a heat dissipation cavity formed by enclosing the motor housing, an air inlet channel and an air outlet channel communicating with the heat dissipation cavity.

[0009] By setting the first heat dissipation channel to include a heat dissipation cavity formed by enclosing the motor housing, an air inlet channel and an air outlet channel communicating with the heat dissipation cavity, the outside air flow can enter the heat dissipation cavity through the air inlet duct to dissipate heat from the motor body. Thus, the air flow can be focused to effectively dissipate heat from the heating component, the motor body, of the brushless motor, further improving the heat dissipation efficiency and avoiding the situation where the air flow scatters after entering the first heat dissipation channel, resulting in less air flow passing through the motor body and poor heat dissipation effect. At the same time, the air flow after dissipating heat from the motor body can be directly discharged outward through the air outlet channel, reducing the residence time of the hot air in the cup holder and increasing the gas flow rate.

[0010] In a preferred implementation of a food processor with good heat dissipation, the air inlet channel includes a cup holder air inlet provided on the side wall of the cup holder and communicating with the outside, and a motor air inlet provided on the motor housing. The air outlet channel includes a cup holder air outlet provided on the side wall of the cup holder and communicating with the outside, and a motor air outlet provided on the motor housing.

[0011] By setting the air inlet channel to include a cup holder air inlet provided on the side wall of the cup holder and communicating with the outside and a motor air inlet provided on the motor housing, and the air outlet channel to include a cup holder air outlet provided on the side wall of the cup holder and communicating with the outside and a motor air outlet provided on the motor housing, the heat dissipation path of the air flow to the brushless motor is: cup holder air inlet - motor air inlet - heat dissipation cavity - motor body - motor air outlet - cup holder air outlet, so that the flow path of the air flow in the cup holder is the shortest, further shortening the residence time of the air flow in the cup holder, increasing the air flow rate passing through the motor body per unit time, and thus further improving the heat dissipation efficiency of the brushless motor.

[0012] In a preferred implementation of a food processor with good heat dissipation, an installation groove is provided at the top of the main body, the cup body assembly is detachably disposed in the installation groove, and avoidance openings for avoiding the cup holder air inlet and the cup holder air outlet are provided on the groove wall of the installation groove.

[0013] By providing an installation groove at the top of the main body and detachably installing the cup assembly in the installation groove, the contact area between the cup assembly and the main body is increased to effectively limit the cup assembly, ensuring the stability of the connection and cooperation between the cup assembly and the main body. This avoids the situation where the cup assembly vibrates greatly or even topples during food processing due to unstable cooperation with the main body, ensuring its working stability. At the same time, the groove wall of the installation groove is provided with avoidance openings for the air inlet and outlet of the cup holder, enabling external air to enter the cup holder through the avoidance openings when entering, and also allowing the airflow after cooling the brushless motor to quickly discharge to the outside through the avoidance openings when discharging to the outside. This effectively avoids the situation where the installation groove blocks the airflow, resulting in a slow airflow rate and poor heat dissipation effect, ensuring the heat dissipation effect of the brushless motor.

[0014] In a preferred implementation of a food processor with good heat dissipation, the air inlet channel includes a first air inlet duct provided in the installation cavity and communicating with the heat dissipation cavity, and a second air inlet duct provided in the accommodation cavity and communicating the first air inlet duct with the outside. The air outlet channel includes a first air outlet duct provided in the installation cavity and communicating with the heat dissipation cavity, and a second air outlet duct provided in the accommodation cavity and communicating the first air outlet duct with the outside.

[0015] By setting the air inlet channel as the first air inlet duct and the second air inlet duct and the air outlet channel as the first air outlet duct and the second air outlet duct, the airflow needs to pass through the main body first before entering the heat dissipation cavity when entering, and also needs to pass through the main body before discharging to the outside when discharging. This increases the probability of the airflow colliding with various components inside the main body when passing through the main body, and thus can achieve noise reduction when the airflow passes through the main body, helping to improve the noise reduction effect and avoiding the situation of relatively large noise discharged to the outside.

[0016] In a preferred implementation of a food processor with good heat dissipation, the second heat dissipation channel includes a third air inlet of the main body housing and a third air outlet of the main body housing, and the power board is arranged between the third air inlet of the main body and the third air outlet of the main body.

[0017] By including the third air inlet of the main body housing and the third air outlet of the main body housing in the second heat dissipation channel, the airflow for cooling the power board enters the main body through the third air inlet of the main body to effectively cool the power board, and the airflow after heat dissipation discharges to the outside through the third air outlet of the main body. And the power board is arranged between the third air inlet of the main body and the third air outlet of the main body, enabling the airflow to completely pass through the power board before discharging to the outside, greatly increasing the contact area and time between the airflow and the power board, and thus improving the heat dissipation efficiency of the airflow to the power board.

[0018] In a preferred implementation of a food processor with good heat dissipation effect, an air guide cover is also provided in the main body shell and is arranged above the power board. The second heat dissipation channel also includes a heat dissipation cavity formed by the air guide cover and the power board. The third main body air inlet and the third main body air outlet are connected to the heat dissipation cavity.

[0019] By also providing an air guide cover above the power board in the main body shell, the air guide cover and the power board cooperate to form a heat dissipation cavity, so that the airflow entering the main body shell can enter the heat dissipation cavity through the guidance of the air guide cover, so that more airflow passes through the power board, thereby achieving effective heat dissipation of the power board, the main heat-generating component, and further improving the heat dissipation effect, avoiding the situation where the airflow entering the main body shell through the air inlet is scattered, resulting in less airflow flowing through the power board and causing poor heat dissipation effect. At the same time, the heat dissipation cavity is connected to the third host air inlet and the third host air outlet, and the air guide cover connects the third host air inlet and the third host air outlet, so that the heat dissipation airflow path in the main body shell is the third host air inlet-heat dissipation cavity-third host air outlet, thereby achieving the maximum heat dissipation efficiency of the power board, which helps to further improve the heat dissipation effect.

[0020] In a preferred implementation of a food processor with good heat dissipation effect, the power board is also covered with heat dissipation fins, a plurality of heat dissipation fins are arranged side by side, and an air guide gap is formed between two adjacent heat dissipation fins, and the air guide gap is in the same direction as the gas flow in the heat dissipation cavity; or,

[0021] The air guide gap is perpendicular to the gas flow direction in the heat dissipation cavity.

[0022] By covering the power board with heat dissipation fins, and arranging a plurality of heat dissipation fins side by side, and forming an air guide gap between two adjacent heat dissipation fins, the airflow passing through the vicinity of the power board can be quickly propagated outward through the heat dissipation fins, and at the same time, the formation of the air guide gap allows the heat dissipation air to quickly take away the heat on the heat dissipation fins through the air guide gap, further improving the heat dissipation efficiency. In addition, the air guide gap is in the same direction as the gas flow in the heat dissipation cavity, so that the airflow can pass through the air guide gap more quickly, thereby further improving the heat dissipation effect.

[0023] By setting the air guide gap to be perpendicular to the gas flow direction in the heat dissipation cavity, the airflow needs to go through multiple circuitous bends in the air guide gap after entering the host housing before it can flow to the third host air outlet, thereby increasing the residence time of the airflow in the host housing and further improving the heat dissipation effect.

[0024] In a preferred implementation of a food processor with good heat dissipation effect, a heat dissipation fan is further provided in the second heat dissipation channel.

[0025] By providing a cooling fan in the second cooling channel, the air flow rate in the second cooling channel is further increased by the driving of the cooling fan, so that the air flow rate passing through the power supply board per unit time is further increased, and the cooling effect on it is further improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] To more clearly illustrate the overall concept of the present utility model, the following will be described in detail by way of example in combination with the accompanying drawings of the specification.

[0037] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0038] As Figures 1 to 7 shown, the present utility model provides a food processor with good heat dissipation effect, including a main body 2 and a cup assembly detachably disposed on the main body 2. The cup assembly includes a cup body 1, a brushless motor 7 disposed below the cup body 1, and a cup base 6 fixedly connected to the bottom of the cup body 1. The cup base 6 and the cup body 1 enclose an installation cavity for accommodating the brushless motor 7. The main body 2 includes a main body housing 21 forming an accommodation cavity. A power board 3 cooperating with the brushless motor 7 is disposed in the accommodation cavity. A first heat dissipation channel communicating with the outside and dissipating heat from the brushless motor 7 is formed in the installation cavity, and a second heat dissipation channel communicating with the outside and dissipating heat from the power board 3 is formed in the accommodation cavity. The first heat dissipation channel and the second heat dissipation channel do not communicate with each other.

[0039] In this application, by using the brushless motor 7 and relying on the characteristics of the brushless motor 7, when the user uses the food processor to process food materials, the noise generated by the rotation of the motor is lower, achieving the effect of noise reduction. At the same time, the brushless motor 7 can achieve variable frequency control, enabling the food processor to control the brushless motor 7 to output different speeds according to different food materials and during the processing process, which can make the processing effect of the food materials better and the processing more sufficient, improving the output taste of the food materials. Moreover, the brushless motor 7 occupies less space, which helps to improve the compactness of the internal structure of the whole machine, reduce the occupied space of the food processor, and facilitate the user to store.

[0040] At the same time, a first heat dissipation channel communicating with the outside and dissipating heat from the brushless motor 7 is formed in the installation cavity, and a second heat dissipation channel communicating with the outside and dissipating heat from the power board 3 is formed in the accommodation cavity, enabling the brushless motor 7 and the power board 3 to respectively dissipate heat in the first heat dissipation channel and the second heat dissipation channel, effectively reducing the temperature rise of the brushless motor 7 and the power board 3, avoiding the situation that the obvious temperature rise of the brushless motor 7 and the power board 3 causes their aging to accelerate, greatly improving the heat dissipation effect and reliability of the power board 3 and the brushless motor 7, helping to extend the service life of the brushless motor 7 and the power board 3, and ensuring their working stability.

[0041] Meanwhile, the first heat dissipation channel and the second heat dissipation channel are not communicated with each other, so that the airflow entering the first heat dissipation channel can only dissipate heat from the brushless motor 7, and the airflow entering the second heat dissipation channel can only dissipate heat from the power supply board 3. The heat dissipation processes do not interfere with each other, avoiding the situation that the airflow after dissipating heat from the brushless motor 7 dissipates heat from the power supply board 3 again due to the communication between the first heat dissipation channel and the second heat dissipation channel, resulting in a smaller temperature difference between the subsequent airflow passing through the power supply board 3 and the power supply board 3 or even the temperature of the airflow being higher than that of the power supply board 3, causing a poor heat dissipation effect or even temperature rise of the power supply board 3. It can effectively improve the heat dissipation efficiency, and the airflow can be quickly discharged outwards after passing through the brushless motor 7 and the power supply board 3, improving the flow rate of the airflow in the first heat dissipation channel and the second heat dissipation channel, and further increasing the air volume passing through the brushless motor 7 and the power supply board 3 per unit time, thereby further enhancing the heat dissipation efficiency.

[0042] As a preferred embodiment of the present application, as Figures 3 to 7 shown, the brushless motor 7 includes a motor housing 72 and a motor body 71 disposed inside the motor housing 72. The first heat dissipation channel includes a heat dissipation cavity 73 formed by enclosing the motor housing 72, an air inlet channel, and an air outlet channel communicating with the heat dissipation cavity 73.

[0043] By setting the first heat dissipation channel to include the heat dissipation cavity 73 formed by enclosing the motor housing 72, an air inlet channel, and an air outlet channel communicating with the heat dissipation cavity 73, the outside airflow can enter the heat dissipation cavity 73 through the air inlet duct to dissipate heat from the motor body 71, so that the airflow can be focused to effectively dissipate heat from the heat-generating component, the motor body 71, of the brushless motor 7, further improving the heat dissipation efficiency, avoiding the situation that the airflow entering the first heat dissipation channel spreads out and the airflow passing through the motor body 71 is less, resulting in a poor heat dissipation effect. At the same time, the airflow after dissipating heat from the motor body 71 can be directly discharged outwards through the air outlet channel, reducing the residence time of the hot air in the cup holder 6 and increasing the gas flow rate.

[0044] It should be noted that the present application does not specifically limit the air inlet channel and the air outlet channel in this embodiment, and it can be any one of the following embodiments:

[0045] Embodiment 1: As Figure 3 、 Figure 4 shown, in this embodiment, the air inlet channel includes a cup holder air inlet 61 provided on the side wall of the cup holder 6 and communicating with the outside, and a motor air inlet 721 provided on the motor housing 72. The air outlet channel includes a cup holder air outlet 62 provided on the side wall of the cup holder 6 and communicating with the outside, and a motor air outlet 722 provided on the motor housing 72.

[0046] By setting the air inlet passage to include a cup base air inlet 61 provided on the side wall of the cup base 6 and communicating with the outside, and a motor air inlet 721 provided on the motor housing 72, and the air outlet passage including a cup base air outlet 62 provided on the side wall of the cup base 6 and communicating with the outside, and a motor air outlet 722 provided on the motor housing 72, the heat dissipation path of the airflow to the brushless motor 7 is: cup base air inlet 61 - motor air inlet 721 - heat dissipation cavity 73 - motor body 71 - motor air outlet 722 - cup base air outlet 62, so that the flow path of the airflow in the cup base 6 is the shortest, thereby further shortening the residence time of the airflow in the cup base 6, increasing the airflow volume passing through the motor body 71 per unit time, and thus further improving the heat dissipation efficiency of the brushless motor 7.

[0047] Further, as Figure 2 , Figure 4 shown, an installation groove 22 is provided at the top of the main body 2, the cup body assembly is detachably arranged in the installation groove 22, and the groove wall of the installation groove 22 is provided with avoidance openings 213 for avoiding the cup base air inlet 61 and the cup base air outlet 62.

[0048] By providing an installation groove 22 at the top of the main body 2 and detachably arranging the cup body assembly in the installation groove 22, the contact area between the cup body assembly and the main body 2 is increased to effectively limit the cup body assembly, ensure the stability of the connection and cooperation between the cup body assembly and the main body 2, avoid the situation that the cup body assembly vibrates greatly or even topples during food processing due to unstable cooperation with the main body 2, and ensure its working stability. At the same time, the groove wall of the installation groove 22 is provided with avoidance openings 213 for avoiding the cup base air inlet 61 and the cup base air outlet 62, so that the outside air can enter through the avoidance openings 213 when entering the cup base 6, and at the same time, the airflow after dissipating heat from the brushless motor 7 can also be quickly discharged to the outside through the avoidance openings 213, effectively avoiding the situation that the installation groove 22 blocks the airflow and causes the airflow flow rate to be slow, resulting in poor heat dissipation effect, and ensuring the heat dissipation effect of the brushless motor 7.

[0049] It should be further noted that the cooperation between the cup body assembly and the main body 2 in this application is not limited to the above settings. It can also be that an installation platform is formed on the top surface of the main body 2, and the cup body assembly is directly fixedly installed above the installation platform; or a ring rib extending upward is formed on the top surface of the main body 2, and the cup body assembly is installed in the ring rib, and the height of the ring rib is not higher than the heights of the cup base air inlet 61 and the cup base air outlet 62.

[0050] Embodiment 2: As Figure 6 , Figure 7As shown, in this embodiment, the air intake channel includes a first air intake duct provided in the installation cavity and communicating with the heat dissipation cavity 73, and a second air intake duct provided in the accommodation cavity and communicating the first air intake duct with the outside. The air outlet channel includes a first air outlet duct provided in the installation cavity and communicating with the heat dissipation cavity 73, and a second air outlet duct provided in the accommodation cavity and communicating the first air outlet duct with the outside.

[0051] By setting the air intake channel as the first air intake duct and the second air intake duct, and the air outlet channel as the first air outlet duct and the second air outlet duct, when the air flow enters the heat dissipation cavity 73, it needs to pass through the main unit 2 first and then enter the heat dissipation cavity 73. At the same time, when the air flow is discharged to the outside, it also needs to pass through the main unit 2 before being discharged to the outside, so that the probability of collision between the air flow and the components inside the main unit 2 is increased when passing through the main unit 2. Furthermore, the air flow can achieve noise reduction and noise elimination when passing through the main unit 2, which helps to improve the noise reduction effect and avoid the situation of relatively large noise discharged to the outside.

[0052] As a preference under this embodiment, as Figure 6 、 Figure 7 shown, the first air intake duct includes a cup holder air intake 61 provided on the bottom wall of the cup holder 6, the second air intake duct includes a first main unit air outlet 215 provided on the top wall of the main unit housing 21 and vertically aligned with the cup holder air intake 61, and a first main unit air intake 214 provided on the side wall or the bottom wall of the main unit housing 21.

[0053] As a preference under this embodiment, as Figure 6 、 Figure 7 shown, the first air outlet duct includes a cup holder air outlet 62 provided on the bottom wall of the cup holder 6, the second air outlet duct includes a second main unit air intake 217 provided on the top wall of the main unit housing 21 and vertically aligned with the cup holder air outlet 62, and a second main unit air outlet 216 provided on the side wall or the bottom wall of the main unit housing 21.

[0054] As a preferred embodiment of the present application, as Figure 6 、 Figure 7 shown, the second heat dissipation channel includes a third main unit air intake 211 and a third main unit air outlet 212 provided on the main unit housing 21, and the power board 3 is arranged between the third main unit air intake 211 and the third main unit air outlet 212.

[0055] By including a second heat dissipation channel with a third host air inlet 211 and a third host air outlet 212 provided on the host housing 21, the airflow for dissipating heat from the power board 3 enters the host 2 through the third host air inlet 211 to effectively dissipate heat from the power board 3. At the same time, the airflow after heat dissipation is discharged outward through the third host air outlet 212. And the power board 3 is arranged between the third host air inlet 211 and the third host air outlet 212, so that the airflow can be completely discharged to the outside after passing through the power board 3, greatly increasing the contact area and time between the airflow and the power board 3, thereby improving the heat dissipation efficiency of the airflow for the power board 3.

[0056] As a preference under this embodiment, as Figure 2 shown, a wind guide cover 8 covering the upper part of the power board 3 is further provided in the host housing 21. The second heat dissipation channel further includes a heat dissipation cavity 73 formed by the cooperation of the wind guide cover 8 and the power board 3. The third host air inlet 211 and the third host air outlet 212 communicate with the heat dissipation cavity 73.

[0057] By further providing a wind guide cover 8 covering the upper part of the power board 3 in the host housing 21, and the wind guide cover 8 and the power board 3 cooperate to form a heat dissipation cavity 73, the airflow entering the host housing 21 can be guided into the heat dissipation cavity 73 through the wind guide cover 8, enabling more airflow to pass through the power board 3, thereby achieving effective heat dissipation of the main heat-generating component, the power board 3, further improving its heat dissipation effect, and avoiding the situation where the airflow entering the host housing 21 through the air inlet spreads out, resulting in less airflow passing through the power board 3 and poor heat dissipation effect. At the same time, the heat dissipation cavity 73 communicates with the third host air inlet 211 and the third host air outlet 212, realizing that the wind guide cover 8 connects the third host air inlet 211 and the third host air outlet 212, so that the heat dissipation airflow path in the host housing 21 is the third host air inlet 211 - heat dissipation cavity 73 - third host air outlet 212, thus achieving the maximum heat dissipation efficiency for the power board 3 and helping to further improve the heat dissipation effect.

[0058] Furthermore, as Figure 2 shown, heat dissipation fins 4 are further covered on the power board 3. A plurality of heat dissipation fins 4 are arranged side by side, and a wind guide gap is formed between adjacent two heat dissipation fins 4.

[0059] By further covering heat dissipation fins 4 on the power board 3, and a plurality of heat dissipation fins 4 are arranged side by side, and a wind guide gap is formed between adjacent two heat dissipation fins 4, the airflow near the power board 3 can quickly spread out through the heat dissipation fins 4. At the same time, the formation of the wind guide gap enables the heat dissipation air to quickly take away the heat on the heat dissipation fins 4 through the wind guide gap, further improving the heat dissipation efficiency.

[0060] It should be noted that the present application does not specifically limit the relative relationship between the air guiding gap and the air flow direction in the heat dissipation cavity 73, and it can be any one of the following embodiments:

[0061] Embodiment 1: As shown in Figure 2 , the air guiding gap is in the same direction as the gas flow direction in the heat dissipation cavity 73.

[0062] By setting the air guiding gap in the same direction as the gas flow direction in the heat dissipation cavity 73, the air flow can pass through the air guiding gap more quickly, thereby further improving the heat dissipation effect.

[0063] Embodiment 2: In this embodiment, the air guiding gap is perpendicular to the gas flow direction in the heat dissipation cavity 73.

[0064] By setting the air guiding gap perpendicular to the gas flow direction in the heat dissipation cavity 73, the air flow needs to pass through multiple detours and bends in the air guiding gap after entering the main body housing 21 before it can flow to the third main body air outlet 212, which increases the residence time of the air flow in the main body housing 21, and thus can further improve the heat dissipation effect.

[0065] As a preferred embodiment of the present application, as shown in Figure 2 , a heat dissipation fan 5 is further provided in the second heat dissipation channel.

[0066] By providing a heat dissipation fan 5 in the second heat dissipation channel, the air flow rate in the second heat dissipation channel is further increased by the drive of the heat dissipation fan 5, thereby further increasing the air flow rate passing through the power supply board 3 per unit time and further improving its heat dissipation effect.
