Description

Technical Field

[0001] This utility model relates to the field of hair removal device technology, and in particular to a hair removal device with dual cooling fans. Background Technology

[0002] Existing hair removal devices generate a lot of heat when in operation, so a heat sink is needed inside the device to dissipate heat. Traditional hair removal devices usually use heat sinks or a combination of heat sinks and a cooling fan for heat dissipation, and usually only one cooling fan is used.

[0003] When the hair removal device operates at high power, it generates high temperatures. Traditional cooling fans require high-powered fans to dissipate heat and ensure the device functions properly. However, high-powered fans are bulky, making the device larger and less convenient for users to carry around. When the device operates at low power, the heat generated is lower, and only a slight increase in airflow to the cooling fins is needed for normal operation. Using a high-powered cooling fan in this case would be a waste of energy.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention provides a hair removal device with dual cooling fans, which can select one or two cooling fans for heat dissipation according to the working conditions of the hair removal device, thereby greatly reducing energy consumption.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hair removal device with dual cooling fans includes a housing, in which a laser module and a control module are disposed. The laser module is connected to a heat dissipation pipe via a heat-conducting block. One end of the heat dissipation pipe is connected to a heat dissipation fin. An air inlet is disposed on the housing. Two cooling fans are disposed on the heat dissipation fin. The control module is connected to the cooling fans and the laser module. The two cooling fans are disposed adjacent to each other, and the cooling fans are located between the air inlet and the heat dissipation fin.

[0008] Furthermore, the projected area of ​​the side of the heat dissipation fin where the cooling fan is located is smaller than the sum of the areas of the air outlet surfaces of the two cooling fans.

[0009] Furthermore, the rated power of the two cooling fans is different.

[0010] Furthermore, the blades of the two cooling fans have different tilt angles.

[0011] Furthermore, the cooling fan is provided with a buckle, and the cooling fins are provided with a locking slot, and the buckle engages with the locking slot.

[0012] Furthermore, a temperature sensor for detecting the heat dissipation fins is provided inside the housing, and the temperature sensor is connected to the control module.

[0013] Furthermore, the control module includes a control circuit, which includes a control chip, a first resistor, a second resistor, a first MOSFET, and a second MOSFET. The PA1 pin of the control chip is connected to the gate of the first MOSFET through the first resistor. The source of the first MOSFET is connected to one of the cooling fans. The PA0 pin of the control chip is connected to the gate of the second MOSFET through the second resistor. The source of the second MOSFET is connected to another cooling fan. The drains of the first MOSFET and the drains of the second MOSFET are grounded.

[0014] Furthermore, when the temperature sensor detects that the temperature of the heat sink fins is greater than a preset temperature, the control module controls the two cooling fans to work simultaneously.

[0015] Furthermore, when the temperature sensor detects that the temperature of the heat sink fins is lower than a preset temperature, the control module controls one of the heat sink fans to operate.

[0016] Furthermore, the exhaust surface areas of the two cooling fans are different.

[0017] Compared to existing technologies, the hair removal device with dual cooling fans provided by this utility model includes a housing, within which a laser module and a control module are housed. The laser module is connected to a heat dissipation pipe via a heat-conducting block, and one end of the heat dissipation pipe is connected to a heat dissipation fin. An air inlet is provided on the housing, and two cooling fans are mounted on the heat dissipation fins. The control module is connected to the cooling fans and the laser module. The two cooling fans are arranged adjacent to each other, with each fan positioned between the air inlet and the heat dissipation fins. This utility model allows for the selection of one or two cooling fans for heat dissipation based on the operating conditions of the hair removal device, significantly reducing energy consumption.

[0032] like Figure 1 and Figure 2As shown, the hair removal device with dual cooling fans 7 provided by this utility model includes a housing 1. A laser module 2 and a control module are disposed inside the housing 1. The laser module 2 is connected to a heat dissipation pipe through a heat-conducting block 3. The heat-conducting block 3 can direct the heat energy generated by the laser module 2 to a designated position, which is convenient for the design of the hair removal device. One end of the heat dissipation pipe is connected to a heat dissipation fin 5. An air inlet 6 is provided on the housing 1. Two cooling fans 7 are provided on the heat dissipation fin 5. The control module is connected to the cooling fans 7 and the laser module 2. The two cooling fans 7 are arranged adjacent to each other, which can concentrate the airflow when the two cooling fans 7 work at the same time. The cooling fans 7 are located between the air inlet 6 and the heat dissipation fin 5. The air inlet 6 facilitates rapid air intake, allowing the cooling fans 7 to blow the airflow towards the heat dissipation fin 5, which has a better heat dissipation effect on the heat dissipation fin 5.

[0033] It should be noted that the control module can control both cooling fans 7 to work simultaneously or one of the cooling fans 7 to work. That is, it can dissipate heat from the heat sink 5 in different ways according to the heat generated by the laser module 2. It can be understood that different users will choose different working levels for hair removal, and the working power of different working levels is different. Therefore, the heat generated by different working levels is different. The control module can select an appropriate heat dissipation method to dissipate heat from the cooling fan 7 according to the actual temperature of the heat sink 5.

[0034] Compared with the prior art, the technical solution of this utility model can select one or two cooling fans 7 for heat dissipation according to the working status of the hair removal device, which greatly reduces energy consumption.

[0035] Furthermore, the projected area of ​​the side of the heat dissipation fin 5 where the cooling fan 7 is located is smaller than the sum of the areas of the air outlet surfaces of the two cooling fans 7. That is, the air outlet surface of the cooling fan 7 covers the entire heat dissipation fin 5, which can ensure that the cooling fan 7 dissipates heat from all parts of the heat dissipation fin 5, resulting in better heat dissipation effect.

[0036] Furthermore, the rated power of the two cooling fans 7 is different. It is understood that when a user uses different speed settings for hair removal, the control module can select the appropriate rated power of the cooling fan 7 for heat dissipation based on the actual heat generation, thereby minimizing energy loss.

[0037] Furthermore, the blades of the two cooling fans 7 have different tilt angles. It should be noted that the different tilt angles of the blades of the two cooling fans 7 result in different airflow directions. That is, the tilt angle of the blades of the cooling fans 7 affects whether the airflow from the cooling fans 7 is more concentrated or dispersed. The different tilt angles of the blades of the two cooling fans 7 allow for a varied airflow direction onto the heat dissipation fins 5, ensuring that airflow passes over all parts of the heat dissipation fins 5, thereby achieving better heat dissipation.

[0038] Furthermore, the cooling fan 7 is provided with a clip 8, and the heat dissipation fin 5 is provided with a locking slot 9, with the clip 8 engaging with the locking slot 9. It can be understood that the engagement between the cooling fan 7 and the heat dissipation fin 5 facilitates their installation, and the direct engagement eliminates the need for a traditional fan bracket, allowing for a smaller size of the hair removal device and making it more convenient for users to carry when out and about.

[0039] Furthermore, a temperature sensor for detecting the heat dissipation fins 5 is provided inside the housing 1, and the temperature sensor is connected to the control module. The temperature sensor can detect the temperature of the heat dissipation fins 5, thereby transmitting the temperature signal to the control module. The control module controls the cooling fan 7 to operate in different modes for heat dissipation based on the temperature signal, effectively improving the heat dissipation efficiency.

[0040] Furthermore, such as Figure 3 , Figure 4 and Figure 5 As shown, the control module includes a control circuit, which includes a control chip U, a first resistor R1, a second resistor R2, a first MOSFET Q1, and a second MOSFET Q2. The PA1 pin of the control chip U is connected to the gate of the first MOSFET Q1 through the first resistor R1. The source of the first MOSFET Q1 is connected to one of the cooling fans 7. The PA0 pin of the control chip U is connected to the gate of the second MOSFET Q2 through the second resistor R2. The source of the second MOSFET Q2 is connected to another cooling fan 7. The drains of the first MOSFET Q1 and the second MOSFET Q2 are grounded. It is understood that the control chip U is model FT61FC45_TRB. Through the PA0 and PA1 pins, the two cooling fans 7 can be controlled individually, allowing both cooling fans 7 to operate simultaneously or one cooling fan 7 to operate independently, thereby achieving better heat dissipation.

[0041] Furthermore, when the temperature sensor detects that the temperature of the heat dissipation fins 5 is higher than the preset temperature, the control module controls the two cooling fans 7 to work simultaneously. It can be understood that when the temperature of all three heat dissipation fins 5 is higher than the preset temperature, it indicates that the hair removal device is operating at a higher power level, generating more heat. Therefore, the two cooling fans 7 need to work simultaneously to dissipate heat from the heat dissipation fins 5, ensuring the hair removal device can function normally.

[0042] Furthermore, when the temperature sensor detects that the temperature of the heat dissipation fins 5 is lower than a preset temperature, the control module controls one of the cooling fans 7 to operate. It is understood that when the temperature of the heat dissipation fins 5 is lower than the preset temperature, it means that the heat generated during the operation of the hair removal device is lower. Therefore, only one cooling fan 7 is needed for heat dissipation, eliminating the need to turn on both cooling fans 7 simultaneously, effectively reducing energy consumption.

[0043] Furthermore, the two cooling fans 7 have different exhaust surface areas. It should be noted that the exhaust surface area of ​​the cooling fan 7 determines the air volume of the cooling fan 7. Using two cooling fans 7 with different exhaust surfaces can meet the heat generated when the hair removal device is working at different speeds, ensuring that the cooling fans 7 can be used to dissipate heat when the hair removal device is working at different speeds, thereby maximizing energy savings.

[0044] In summary, the hair removal device with dual cooling fans provided by this utility model has cooling fans whose exhaust surfaces cover the entire heat dissipation fins, ensuring effective heat dissipation for all parts of the fins. The different tilt angles of the two fan blades ensure airflow across all parts of the heat dissipation fins, further enhancing cooling efficiency. The different rated power of the two fans allows for selection of the appropriate fan, minimizing energy consumption. This utility model allows for the selection of one or two cooling fans based on the device's operating conditions, significantly reducing energy loss.

[0045] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the scope of protection of the present invention.
