Description

Technical Field

[0001] The present invention relates to the technical field of personal care products, in particular to a temperature control method for a shaver and the shaver. Background Art

[0002] A razor cuts hair by rotating or oscillating its blades at high speeds, which can easily cause the blade mesh to heat up, causing a burning sensation on the skin and even redness and swelling, severely impacting the user experience. Consequently, razors with cooling functions are now available on the market, offering users a cool feeling during shaving. However, since these only have a simple cooling function, when the cooling capacity of the cooling module is excessive, the temperature of the blade structure can easily drop too low, causing the skin to feel excessively cold; when the cooling capacity of the cooling module is insufficient, the temperature of the blade structure can easily rise, causing the skin to feel insufficiently cool. Therefore, existing razors with cooling functions still have room for improvement. Summary of the Invention

Therefore, they cannot be understood as limiting the present invention.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] See also Figures 1 to 5 The present invention discloses a temperature control method for a shaver and a shaver. The shaver includes a cutter head structure, a control module and a detection structure. The cutter head structure includes a mounting seat 11, a cutter assembly 12 and a cooling module 13. The mounting seat 11 is provided with a first mounting port 111, the cutter assembly 12 is provided at the first mounting port 111, and the cooling module 13 is provided at the mounting seat 11.

[0027] It is understandable that the refrigeration module 13 has a cooling end 131 and a heat dissipation end 132 . The heat dissipation end 132 acts on the cooling end 131 to reduce the temperature of the cooling end 131 . The cooling end 131 is used to reduce the thermal sensitivity of the human body.

[0028] The temperature control method includes:

[0029] Step S1: After the cooling function of the shaver is turned on, the first detection component 101 of the detection structure 10 obtains the temperature of the cutter head structure, and the control module controls the cooling module 13 to operate according to the temperature obtained by the first detection component 101; specifically, when the temperature obtained by the first detection component 101 is greater than or within a first preset range, the control module controls the cooling module 13 to operate normally for cooling; when the temperature obtained by the first detection component 101 is lower than the first preset range, the control module controls the cooling module 13 to suspend operation.

[0030] With such a configuration, the cooling end 131 of the refrigeration module 13 can reduce the thermal sensitivity of human skin, preventing the human skin from feeling hot or even red and swollen. More importantly, the control module controls the operation of the refrigeration module 13 in the cutter head structure according to the temperature obtained by the first detection component 101, thereby achieving the purpose of controlling the refrigeration capacity of the refrigeration module 13. In this way, the problem of excessive refrigeration capacity causing the user to feel excessively cold, and the problem of insufficient refrigeration capacity causing the user to feel insufficiently cool are avoided. This allows the temperature of the cutter head structure to be maintained in a comfortable temperature range, further optimizing the user's experience.

[0031] It is understandable that in order to better control the operation of the refrigeration module 13, it is very important to detect the temperature of the refrigeration module 13. Figure 2 and Figure 3As shown, further, in this embodiment, the first detection component 101 is used to obtain the temperature of the refrigeration module 13, and the control module 10 can control the operation of the refrigeration module 13 according to the temperature of the refrigeration module 13; specifically, the first detection component 101 and the refrigeration module 13 are in direct thermal contact to improve the accuracy and practicality of temperature detection.

[0032] It can be understood that the temperature of the cooling end 131 of the refrigeration module 13 has the most direct and important impact on the degree of coldness felt by the user. Therefore, preferably, in this embodiment, the first detection component 101 is in direct thermal contact with the cooling end 131 of the refrigeration module 13 to obtain the temperature of the cooling end 131 of the refrigeration module 13. The control module 10 can control the operation of the refrigeration module 13 according to the temperature of the cooling end 131 of the refrigeration module 13, thereby accurately controlling the degree of coldness felt by human skin.

[0033] Of course, in some other embodiments, the first detection element 101 may also be in direct thermal contact with the heat dissipation end 132 of the refrigeration module 13 to obtain the temperature of the heat dissipation end 132 of the refrigeration module 13 .

[0034] It should be noted that, in some other embodiments, the detection structure 10 may further include other detection components to obtain the temperature of structures such as the mounting seat 11 or the cutter assembly 12, and this is not limited here.

[0035] Specifically, in this embodiment, the cutter head structure also includes a first heat dissipation frame 14, which is in thermal contact with the heat dissipation end 132 of the refrigeration module 13. The first heat dissipation frame 14 is formed of a heat-conducting material. The first heat dissipation frame 14 has good thermal conductivity and can quickly and fully absorb the heat transferred from the heat dissipation end 132 of the refrigeration module 13, thereby improving the cooling efficiency and cooling effect of the cooling end 131 of the refrigeration module 13, further improving the user experience.

[0036] Furthermore, in this embodiment, the temperature control method further includes:

[0037] Step S2: The second detection component 102 of the detection structure 10 obtains the temperature of the first heat dissipation rack 14; when the temperature obtained by the first detection component 101 is greater than or within the first preset range, and when the temperature obtained by the second detection component 102 is lower than or within the second preset range, the control module controls the refrigeration module 13 to work normally to perform cooling; when the temperature obtained by the second detection component 102 is higher than the second preset range, regardless of any value of the temperature obtained by the first detection component 101, the control module controls the refrigeration module 13 to stop working.

[0038] In this way, the control module can control the operation of the refrigeration module 13 according to the temperature of the first heat dissipation frame 14, and can realize dual temperature detection of different positions of the cutter head structure through the first detection member 101 and the second detection member 102, thereby making the temperature control of the cutter head structure further intelligent, ensuring that the shaver has excellent intelligent refrigeration function, and further improving the user experience; similarly, the second detection member 102 is in direct thermal contact with the first heat dissipation frame 14 to improve the accuracy and practicality of temperature detection.

[0039] Specifically, the first detection element 101 and the second detection element 102 can be, but are not limited to, an NTC, a thermocouple, a temperature control IC, or an infrared temperature control sensor switch. The first detection element 101 and the second detection element 102 can transmit the detected temperature signal to the control module, and the control module then controls the operation of the cooling module 13 based on the input temperature signal. This is a technical means well known to those skilled in the art and will not be described in detail here.

[0040] Preferably, in this embodiment, both the first detection element 101 and the second detection element 102 use NTC. It can be understood that NTC refers to a thermistor with a negative temperature coefficient and whose resistance decreases exponentially with increasing temperature. It has many advantages such as being sensitive to temperature, low in price, fast in response speed, wide in operating temperature range and good in interchangeability.

[0041] Specifically, in this embodiment, the first preset range is 9°C to 13°C, and the second preset range is 48°C to 52°C.

[0042] Furthermore, in this embodiment, the temperature control method includes the following steps:

[0043] Step S3: When the working time of the refrigeration module 13 reaches the rated working time, the control module controls the refrigeration module 13 to stop working.

[0044] For example, the rated working time is configured to be 7 minutes. Specifically, when the shaver is working and the cooling function is turned on, the temperature of the cooling end 131 of the cooling module 13 starts to drop from room temperature and reaches the first preset range after 1 minute. In the next 6 minutes, the temperature of the cooling end 131 of the cooling module 13 is kept within 9°C-13°C. The cooling function of the cooling module 13 is automatically terminated after the working time of the cooling module 13 reaches 7 minutes; and, even if the working time of the cooling module 13 has not reached the rated working time, as long as the temperature of the first heat dissipation frame 14 is higher than the second preset range, the control module immediately controls the cooling module 13 to stop working and stop the cooling function, so that the cooling module 13 will not be burned due to the excessive temperature difference between hot and cold.

[0045] It should be noted that, in some other embodiments, the rated working time may also be configured to be 5 minutes, 6 minutes, or 8 minutes, etc., which is not the only limitation here.

[0046] like Figure 4 and Figure 5 As shown, further, in this embodiment, the cutter assembly 12 can float relative to the first mounting port 111. When the mounting seat 11 is in contact with the human skin, the cutter assembly 12 is pressed downward. The mounting seat 11 is also provided with a second mounting port 112. The cooling end 131 of the refrigeration module 13 is at least partially exposed at the second mounting port 112 to contact the human skin, thereby reducing the thermal sensitivity of the human skin.

[0047] Preferably, in this embodiment, the refrigeration module 13 includes a cooling element and a semiconductor refrigeration element, so that the cooling element is the cooling end 131 of the refrigeration module 13, and the semiconductor refrigeration element is the heat dissipation end 132 of the refrigeration module 13; wherein, the cooling element is at least partially exposed from the second mounting port 112 to be in direct contact with human skin, the cold surface of the semiconductor refrigeration element is in direct thermal contact with the cooling element, and the hot surface of the semiconductor refrigeration element is in direct thermal contact with the first heat dissipation frame 14, so that the semiconductor refrigeration element can absorb the heat of the cooling element and transfer the heat to the first heat dissipation frame 14, so that the cooling element is maintained in a lower temperature range, thereby achieving the purpose of reducing the thermal sensitivity of human skin.

[0048] Semiconductor coolers also offer the following advantages: 1. Environmentally friendly: They require no refrigerant and are pollution-free. They operate continuously, have no rotating parts, no gyration effects, and no sliding components, and are solid-state components. 2. Noiseless: Unlike traditional mechanical refrigeration devices, thermoelectric coolers generate virtually no electronic interference during operation. They can be connected to sensitive electronic sensors without disrupting their operation, and they produce no noise at all. 3. Precise temperature control: Semiconductor coolers are current-converting components that can precisely control temperature within a 0.1°C range by controlling the input current. Combined with temperature sensing and control technology, they can be easily remotely, programmably, or computer-controlled, facilitating the integration of automated control systems. 4. High reliability: Due to their solid-state construction, semiconductor coolers offer high reliability. Although this varies depending on the application conditions, the lifespan of semiconductor coolers can typically exceed 200,000 hours.

[0049] like Figure 3 As shown, specifically, in this embodiment, the cooling member includes a body 1311 and three cooling arms 1312, and the three cooling arms 1312 are radially connected to the body 1311. Of course, in some other embodiments, the cooling arms 1312 can also be but not limited to being arranged around the cutter assembly 12, which is not limited here.

[0050] Preferably, in this embodiment, the cooling element is formed of a heat-conducting metal. In this way, the cooling element has the advantages of low price, stable structure, easy production and long service life. More importantly, it can better absorb heat, thereby better reducing the thermal sensitivity of human skin. Admittedly, in some other embodiments, the cooling element can also be formed of, but not limited to, heat-conducting materials such as stone mill or silicone rubber, which is not limited here.

[0051] It should be noted that, in some other embodiments, the refrigeration module 13 may also include, but is not limited to, a refrigerant structure or a magnetic refrigeration structure, etc., which is not limited here.

[0052] like Figure 2 and Figure 3 As shown, further, in this embodiment, the cutter head structure also includes a fixing frame 19, the first heat dissipation frame 14 supports the fixing frame 19 and the refrigeration module 13, the fixing frame 19 is clamped between the first heat dissipation frame 14 and the cooling element, and the semiconductor refrigeration element is embedded in the fixing frame 19, so as to improve the installation stability and working stability of the semiconductor refrigeration element, and avoid the semiconductor refrigeration element from shaking or falling off, thereby ensuring the overall cooling efficiency of the refrigeration module 13.

[0053] Specifically, in this embodiment, the shaver also includes a second heat dissipation frame 15 and a drive assembly 16. The second heat dissipation frame 15 is also formed of a heat-conducting material. The drive assembly 16 is used to drive the cutter assembly 12 to work. The drive assembly 16 is clamped between the first heat dissipation frame 14 and the second heat dissipation frame 15. In this way, the first heat dissipation frame 14 and the second heat dissipation frame 15 can also absorb the heat generated by the drive assembly 16, so that the drive assembly 16 is in a lower temperature range when working, thereby extending the working life of the drive assembly 16.

[0054] Specifically, in this embodiment, the control module includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, the steps of the above-mentioned temperature control method for the shaver are implemented.

[0055] Preferably, in this embodiment, the shaver further includes an inner liner 17, and the control module, the first heat dissipation frame 14, the second heat dissipation frame 15 and the drive assembly 16 are all located inside the inner liner 17. In this way, on the one hand, the inner liner 17 can play a heat-insulating role to prevent the temperature of the outer shell 18 for the user to hold from being too high. On the other hand, the inner liner 17 can also play a waterproof role to prevent the electronic components inside the shaver from becoming damp and failing.

[0056] In summary, the temperature control method of the shaver provided by the present invention includes the above-mentioned steps S1, S2 and S3. With such a configuration, on the one hand, when the refrigeration function is turned on, the temperature of the cooling end 131 of the refrigeration module 13 can be maintained within a first preset range, and the user will not feel too cold due to excessive refrigeration capacity, nor will the user feel insufficient coolness due to insufficient refrigeration capacity, thereby allowing the user to obtain the best shaving experience; on the other hand, it can avoid the problem of the refrigeration module 13 being easily burned due to the large temperature difference between the first heat dissipation frame 14 and the refrigeration module 13, and can also avoid the problem of the temperature of the first heat dissipation frame 14 abnormally rising due to the excessive refrigeration capacity of the refrigeration module 13, thereby improving the working safety and service life of the refrigeration module 13, saving electricity, and ensuring that the refrigeration function of the shaver is not damaged.

[0057] The technical means disclosed in the solutions of the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
