Description

Technical Field

[0001] The present invention relates to the technical field of hair removal devices, and in particular to a hair removal device with dual cooling fans and a heat dissipation control method thereof. Background Art

[0002] When the hair removal device in the prior art is working, a large amount of heat is generated by the body, so a radiator needs to be provided inside the body to dissipate the heat. The radiator inside the traditional hair removal device with dual cooling fans usually adopts cooling fins, or cooling fins plus cooling fans to dissipate heat, and generally only one cooling fan is used.

[0003] When the hair removal device is working at a high power level, high temperature heat will be generated in the body. Traditional cooling fans need to use high-power fans to dissipate heat to ensure that the hair removal device can work normally. However, high-power fans are large in size, which undoubtedly makes the size of the hair removal device larger and inconvenient for users to carry out. When the hair removal device is working at a low power level, the temperature of the heat generated in the body is relatively low. The hair removal device can work normally by simply increasing the air volume of the cooling fins. At this time, if a large cooling fan with high power is used for heat dissipation, it will undoubtedly lead to energy waste.

[0004] Therefore the prior art needs to be improved and enhanced. Summary of the invention

For those of ordinary skill in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0038] In addition, the terms "first" and "second" etc. used in this application can be used to describe various elements in this article, but these elements are not limited by these terms. These terms are only used to distinguish the first element from another element. When used here, the singular "one", "one" and "said / the" can also include plural forms, unless the context clearly indicates another way.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0040] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] like Figure 1 and Figure 2 As shown, the hair removal device with dual cooling fans provided by the present invention comprises a shell 1, a laser module 2 and a control module are arranged in the shell 1, a heat conducting block 3 is arranged on the backlight side of the laser module 2, the heat conducting block 3 is connected to a heat dissipation pipe 4, heat dissipation fins 5 are arranged on the heat dissipation pipe 4, a temperature sensor, a first cooling fan 6 and a second cooling fan 7 are arranged on the cooling fins, the first cooling fan 6 and the second cooling fan 7 are arranged adjacent to each other, so that the wind force can be concentrated when the two cooling fans work at the same time, the control module is connected to the temperature sensor, the cooling fan and the laser module 2, and when the hair removal device with dual cooling fans is working, the control module is used to separately control the operation of the first cooling fan 6 and the second cooling fan 7 according to the temperature of the cooling fins 5.

[0042] It is understandable that the control module can control the first cooling fan 6 and the second cooling fan 7 to work at the same time, or can only control the first cooling fan 6 or the second cooling fan 7 to work, that is, the heat dissipation system of the hair removal device with dual cooling fans can present a multi-level heat dissipation degree design, which is used to select a suitable heat dissipation method for the heat dissipation fins 5 at different temperatures, thereby greatly reducing energy loss. It should be noted that the temperature of the heat dissipation fins 5 can have a certain degree of representation of the temperature of the laser module 2, that is, the temperature on the heat dissipation fins 5 is close to the temperature of the laser module 2.

[0043] Compared with the prior art, in the technical solution of the present invention, the temperature of the cooling fins 5 is detected by the temperature sensor, and the control module can control the working mode of the first cooling fan 6 and the second cooling fan 7 according to the temperature, thereby achieving the best cooling effect while effectively saving energy consumption.

[0044] Furthermore, the rated power of the first cooling fan 6 is different from the rated power of the second cooling fan 7. It is understandable that when the user uses different gears for hair removal, the control module can select the cooling fan with a suitable rated power for heat dissipation according to the actual heat generation situation, that is, the rated power of the first cooling fan 6 is different from that of the second cooling fan 7, which can cover the heat dissipation conditions under various temperature environments as much as possible. For example, when the ambient temperature is low, using a cooling fan with a lower power can maximize the reduction of energy loss.

[0045] Furthermore, the fan blades of the first cooling fan 6 and the second cooling fan 7 have different inclination angles. It should be noted that the different inclination angles of the fan blades of the two cooling fans will result in different air outlet directions of the first cooling fan 6 and the second cooling fan 7, that is, the inclination angles of the fan blades of the first cooling fan 6 and the second cooling fan 7 will affect whether the air outlet of the cooling fan is more concentrated or dispersed, and the different inclination angles of the fan blades of the first cooling fan 6 and the second cooling fan 7 can achieve a variable airflow direction blowing on the cooling fins 5, that is, it can achieve airflow passing through various parts of the cooling fins 5, thereby achieving heat dissipation of the cooling fins 5, and the heat dissipation effect is better.

[0046] Furthermore, the projected area of ​​the side of the heat dissipation fin 5 where the heat dissipation fan is located is smaller than the sum of the areas of the air outlet surfaces of the first heat dissipation fan 6 and the second heat dissipation fan 7. That is, the air outlet surfaces of the first heat dissipation fan 6 and the second heat dissipation fan 7 cover the entire heat dissipation fin 5, which can ensure that the heat dissipation fan dissipates heat from various parts of the heat dissipation fin 5, and the heat dissipation effect is better.

[0047] Furthermore, the air outlet area of ​​the first cooling fan 6 is smaller than the air outlet area of ​​the second fan. It should be noted that, when the air outlet area of ​​the cooling fan determines the size of the air outlet of the cooling fan, using two cooling fans with different air outlet areas can meet the heat generated when the hair removal device with dual cooling fans works at different gears, ensuring that the cooling fan can be used to dissipate heat when the hair removal device with dual cooling fans works at different gears, thereby maximizing energy saving.

[0048] Furthermore, a buckle 8 is provided on the cooling fan, and a bayonet 9 is provided on the cooling fin 5, and the buckle 8 is engaged with the bayonet 9. It can be understood that the cooling fan is engaged with the cooling fin 5, which facilitates the installation of the cooling fan and the cooling fin 5, and the cooling fan is directly engaged with the cooling fin 5, eliminating the need for a traditional fan bracket, which can make the hair removal device with dual cooling fans smaller in size and convenient for users to carry when going out.

[0049] Furthermore, an air inlet 10 is provided on the shell 1, and the cooling fan is located between the air inlet 10 and the cooling fins 5. The air inlet 10 is convenient for rapid air intake, so that the cooling fan blows the airflow toward the cooling fins 5, which has a better heat dissipation effect on the cooling fins 5.

[0050] The present invention provides a heat dissipation control method for a hair removal device with dual heat dissipation fans, comprising:

[0051] When the hair removal device with dual cooling fans operates at a first preset gear, the control module controls the first cooling fan to operate;

[0052] When the hair removal device with dual cooling fans operates at a second preset gear, the control module controls the second cooling fan to operate;

[0053] When the hair removal device with dual cooling fans operates at the third preset gear, the control module controls the first cooling fan and the second cooling fan to operate simultaneously, wherein the power of the first preset gear, the second preset gear and the third preset gear increases sequentially, and the rated power of the first cooling fan is less than the rated power of the second cooling fan.

[0054] In one embodiment, the first preset gear is the first gear, the second preset gear is the second gear, and the third preset gear is the third gear. When the hair removal device with dual cooling fans works in the first gear, it is in a relatively low power state, and the degree of hair removal is relatively mild. The heat generated by the laser module of the hair removal device with dual cooling fans is also relatively low. When the hair removal device with dual cooling fans works in the second gear, it is in a medium power state, the degree of hair removal is moderate, and the heat generated by the laser module is high. When the hair removal device with dual cooling fans works in the third gear, the heat generated by the laser module is relatively high. Different users will choose a working gear suitable for them for hair removal, and for different working gears, the control module will also control the first cooling fan and the second cooling fan to dissipate heat in different ways.

[0055] It can be understood that the greater the heating power, the more heat is generated during operation, that is, the higher the temperature. The control module can select different heat dissipation methods for heat dissipation according to the heat generated by different preset gears of the hair removal device with dual cooling fans, that is, by only controlling the first cooling fan to work or only controlling the second cooling fan to work, or controlling the first cooling fan and the second cooling fan to work at the same time, the air output of the cooling fan can be matched with the temperature in the environment, ensuring that the appropriate air output can be used to dissipate heat at the appropriate temperature.

[0056] Compared with the prior art, the technical solution of the present invention can control the appropriate air volume according to the appropriate temperature, greatly reducing energy loss and preventing the need for excessive air volume to dissipate heat due to too low a temperature, which would lead to excessive waste of energy.

[0057] Furthermore, when the hair removal device with dual cooling fans operates at a first preset gear, the step of the control module controlling the first cooling fan to operate includes:

[0058] When the temperature sensor detects that the temperature of the heat dissipation fins is within a first preset temperature range, the first heat dissipation fan operates periodically and intermittently;

[0059] When the temperature sensor detects that the temperature of the heat dissipation fins is within the second preset temperature range, the first heat dissipation fan continues to work;

[0060] Among them, the second preset temperature range is greater than the first preset temperature range, and the sum of the first preset temperature range and the second range value is equal to the temperature value range generated by the cooling fins when the hair removal device with dual cooling fans works at the first preset gear.

[0061] In one embodiment, when the hair removal device with dual cooling fans operates at the first preset gear, the temperature value range generated by the cooling fins is (30°, 40°], then the first preset temperature range is (30°, 35°], and the second preset temperature range is (35°, 40°], that is, when the temperature is low, the control module can control the first cooling fan to work indirectly, and when the temperature is high, the first cooling fan is controlled to work continuously to meet the heat dissipation needs, which can effectively reduce energy consumption.

[0062] Furthermore, when the hair removal device with dual cooling fans operates at a second preset gear, the step of the control module controlling the second cooling fan to operate includes:

[0063] When the temperature sensor detects that the temperature of the heat dissipation fin is within a third preset temperature range, the second heat dissipation fan continues to operate at a low speed;

[0064] When the temperature sensor detects that the temperature of the heat dissipation fin is within the fourth preset temperature range, the second heat dissipation fan continues to operate at a high wind speed;

[0065] Among them, the fourth preset temperature range is greater than the third preset temperature range, and the sum of the third preset temperature range and the fourth range value is equal to the temperature value range generated by the cooling fins when the hair removal device with dual cooling fans works at the second preset gear.

[0066] In one embodiment, when the hair removal device with dual cooling fans operates at the second preset gear, the temperature value range generated by the cooling fins is (40°, 50°], then the second preset temperature range is (40°, 45°], and the third preset temperature range is (45°, 50°], that is, when the temperature is low, the control module can control the first cooling fan to continue to operate at a low wind speed gear, and when the temperature is high, the first cooling fan is controlled to continue to operate at a high wind speed gear to meet the heat dissipation needs, which can effectively reduce energy consumption.

[0067] Furthermore, when the hair removal device with dual cooling fans operates at a third preset gear, the step of the control module controlling the first cooling fan and the second cooling fan to operate simultaneously includes:

[0068] When the temperature sensor detects that the temperature of the heat dissipation fins is within a fifth preset temperature range, the first heat dissipation fan and the second heat dissipation fan work alternately;

[0069] When the temperature sensor detects that the temperature of the heat dissipation fins is within a sixth preset temperature range, the first heat dissipation fan and the second heat dissipation fan work simultaneously and continuously;

[0070] Among them, the sixth preset temperature range is greater than the fifth preset temperature range, and the sum of the fifth preset temperature range and the sixth range value is equal to the temperature value range generated by the cooling fins when the hair removal device with dual cooling fans works at the third preset gear.

[0071] In one embodiment, when the hair removal device with dual cooling fans works at the third preset gear, the temperature value range generated by the cooling fins is (50°, 60°], then the fifth preset temperature range is (50°, 55°], and the sixth preset temperature range is (55°, 60°], that is, when the temperature is low, the control module can control the first cooling fan and the second cooling fan to work alternately, that is, after the first cooling fan works for a period of time, it is replaced by the second cooling fan to work for a period of time, and this is an alternating cycle; when the temperature is high, the first cooling fan is controlled to work continuously to meet the heat dissipation needs, which can effectively reduce energy consumption.

[0072] In summary, the hair removal device with dual cooling fans provided by the present invention has different rated powers of the first cooling fan and the second cooling fan, which can cover the cooling conditions under various temperature environments as much as possible. The fan blades of the first cooling fan and the second cooling fan have different inclination angles, which can ensure that air flows through all parts of the cooling fins, thereby achieving heat dissipation for the cooling fins, and the heat dissipation effect is better. The projected area of ​​the side of the cooling fin where the cooling fan is located is smaller than the sum of the areas of the outlet surfaces of the first cooling fan and the second cooling fan, which can ensure that the cooling fan can dissipate heat for all parts of the cooling fins, and the heat dissipation effect is better. According to the present invention, according to the temperature of the cooling fins detected by the temperature sensor, the control module can select to individually control the first cooling fan and the second cooling fan for heat dissipation according to the temperature, thereby greatly reducing energy loss.

[0073] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, which all belong to the protection scope of the present invention.
