For example, in the utility model patent with patent application number 2021211833705, a hair growth cap is proposed, which includes a shell, a hair growth component and a battery assembly. The shell is a cap-shaped structure and has an inner surface that encloses the head. The hair growth component includes a light board installed on the inner surface of the shell. The battery assembly is installed on the shell and electrically connected to the light board. When the light board is powered on, the light source can be raised to the head to promote hair growth; in addition, the shell can be installed on a hat for use, which is easy to use and highly portable.

[0004] However, in actual use, it was found that as the hair growth components and battery components would continue to generate heat, the performance of related components would decline, affecting the treatment effect; it would also cause the temperature inside the hat to rise, causing discomfort to the user's head. Therefore, there is an urgent need to design a new hair growth cap. Utility Model Content

[0039] See attached Figure 1 -Attached Figure 7 A hair growth cap with heat dissipation function comprises a shell 1, a lamp 2, an air supply member 3 and a control unit 4; the shell 1 is installed in the cap P, and an air flow channel 10 connected to the outside is formed between the outer wall of the shell 1 and the inner surface of the cap P, and a sleeve cavity 110 for enclosing the head is provided inside the shell 1; the lamp 2 is installed on the shell 1, and the light emitted by the lamp 2 can be transmitted into the sleeve cavity 110; the air supply member 3 is installed on the shell 1 and is located in the air flow channel 10 to transport the heat in the air flow channel 10 to the outside; the control unit 4 is installed in the shell 1 and is electrically connected to the lamp 2 and the air supply member 3.

[0040] Specifically, when in use, the cap P is held in the hand to enclose the sleeve cavity 110 of the shell 1 around the head to complete the wearing, and then the lamp 2 is started through the control unit 4. The light transmitted by the lamp 2 into the sleeve cavity 110 can stimulate the scalp cells, promote hair growth, and prevent hair loss. During the working process, the heat generated by the lamp 2 and the control unit 4 is conducted to the air flow channel 10 through the shell 1. At this time, the air supply part 3 is started through the control unit 4, and the air supply part 3 draws the external air into the air flow channel 10, and then discharges the heat-carrying gas to the outside to achieve heat dissipation and cooling.

[0041] In summary, the utility model designs a sleeve cavity 110 in the shell 1 to enclose the head, so that the shell 1 can be stably placed on the user's head, and designs a control unit 4 to control the start and stop of the lamp body, so that the light emitted by the lamp body can illuminate the head to promote hair growth; because the hat P is used with the shell 1, it is convenient for users to wear and carry, and the air flow channel 10 between the hat P and the shell 1 can buffer the heat generated by the shell 1, and the design of the air supply part 3 is used to take away the heat in the air flow channel 10, which can not only avoid overheating of the lamp 2 and the control unit 4 and cause performance degradation, thereby ensuring the treatment effect, but also keep the internal temperature of the hat P within a suitable range, thereby improving the comfort of use.

[0042] It should be noted that it is currently known on the market that low-energy laser irradiation can stimulate the scalp and promote hair growth, but considering the possible existence of other astigmatism that can stimulate scalp hair growth, the present invention does not limit the light emitted by the lamp; however, in this embodiment, low-energy laser is preferably used.

[0043] See attached Figure 1 -Attached Figure 7 The shell 1 includes a bottom shell 11, a connecting shell 12 and a top cover 13; the bottom shell 11 is made of transparent material, the sleeve cavity 110 is arranged in the bottom shell 11, and the lamp 2 is installed on the bottom shell 11; the connecting shell 12 is installed on the bottom shell 11 and encloses the lamp 2, and the air supply component 3 and the control unit 4 are both installed on the connecting shell 12; the top cover 13 is installed on the connecting shell 12, and the air flow channel 10 is arranged between the outer wall of the top cover 13 and the inner surface of the hat P. An accommodating cavity 120 for enclosing the air supply component 3 and the control unit 4 is also formed between the top cover 13 and the connecting shell 12, and an air inlet 131 and an air outlet 132 connected to the air flow channel 10 and the air supply component 3 are opened on the side wall of the accommodating cavity 120.

[0044] Specifically, when in use, the lamp 2 is started by the control unit 4, and the light emitted by the lamp 2 passes through the bottom shell 11 to the sleeve cavity 110 to irradiate the scalp for hair growth treatment; during use, the lamp 2 and the control unit 4 will generate heat, causing the temperature of the accommodating cavity 120 to rise, and the top shell will transfer the heat in the accommodating cavity 120 to the air flow channel 10. At this time, the air supply component 3 is started, and the gas entrained with heat in the air flow channel 10 is drawn into the air inlet 131 by the air supply component 3, and discharged to the outside from the air outlet 132, thereby completing the gas circulation inside the hat P, so that the internal temperature of the hat P is maintained within an appropriate range.

[0045] The housing 1 is assembled by means of the bottom shell 11 , the connecting shell 12 and the top cover 13 , which is convenient for production and processing, as well as for installation, disassembly and maintenance of the lamp 2 and the control unit 4 , thus improving convenience.

[0046] It should be noted that the inner surface of the sleeve cavity 110 is generally designed to be arc-shaped to prevent the bottom shell 11 from hitting the head and improve wearing comfort. In order to make the shell 1 more stably placed on the head, the inner surface size of the sleeve cavity 110 can also be customized according to the size of the head; in addition, the bottom shell 11 can be made of transparent plastic, fiberglass and other light-transmitting materials. Due to the variety of related materials, this is not restricted in the present invention.

[0047] See attached Figure 1 -Attached Figure 7 The air supply member 3 is a fan 30, and the connecting shell 12 is provided with a fixing seat 121 in the accommodating cavity 120. The fan 30 is installed on the fixing seat 121, and the air suction end and the air exhaust end of the fan 30 are respectively connected to the air inlet 131 and the air outlet 132.

[0048] Specifically, the fixing seat 121 can limit the fan 30. After the fan 30 is started by the control unit 4, the exhaust end of the fan 30 draws the hot gas in the air flow channel 10 through the air inlet 131, and under the action of wind, the exhaust end of the fan 30 sprays the hot gas out of the air outlet 132 to the outside, so as to reduce the internal temperature of the hat P, ensure the stable operation of the lamp 2 and the control unit 4, and improve the comfort of use.

[0049] It should be noted that, in addition to the fan 30, the air supply member 3 may also use a blower with greater power or other equipment capable of pumping gas. Due to the variety of related structures, this is not limited in the present invention.

[0050] See attached Figure 1 -Attached Figure 7 There are various types of lamps 2 with therapeutic effects, which are not listed one by one in the utility model. For the convenience of understanding, in this embodiment, the lamp 2 includes a plurality of laser light bars 20, and a plurality of limiting grooves 111 are arranged in an array on the top surface of the bottom shell 11. The plurality of laser light bars 20 are installed one by one in the plurality of limiting grooves 111, and the bottom shell 11 is synchronously attached to the plurality of laser light bars 20.

[0051] Among them, the limiting groove 111 can limit the left and right deviation of the laser light bar 20, and the bottom shell 11 can limit the up and down movement of the laser light bar 20, so that the laser lamp body is stably installed on the bottom shell 11; and the array design of multiple limiting grooves 111 allows multiple laser light bars 20 to be evenly distributed on the bottom shell 11 to more comprehensively irradiate the scalp, thereby improving the use effect.

[0052] See attached Figure 1 -Attached Figure 7 The bottom shell 11 and the top cover 13 can both be made of heat-conducting materials. This design allows the bottom shell 11 to transfer the heat generated by the laser light bar 20 when it is working to the accommodating cavity 120 more quickly, while the top cover 13 can transfer the heat in the accommodating cavity 120 to the airflow channel 10 more quickly, so as to effectively improve the heat dissipation efficiency.

[0053] See attached Figure 1 -Attached Figure 7 A heat dissipation hole 133 connected to the air flow channel 10 is also provided on the side wall of the accommodating cavity 120 .

[0054] Specifically, during use, the heat in the accommodating cavity 120 can be dissipated into the air flow channel 10 through the heat dissipation holes 133 to further improve the heat dissipation efficiency.

[0055] See attached Figure 1 -Attached Figure 7The bottom shell 11 is provided with a plurality of legs 112 extending downward on each side of the sleeve cavity 110 , and a card slot P1 opening upward is provided on the bottom edge of the inner surface of the hat P, and the plurality of legs 112 can be inserted into or detached from the card slot P1 .

[0056] Specifically, during installation, the housing 1 is placed inside the hat P, and then the bottom side of the inner surface of the hat P is moved to align the card slot P1 with the plurality of legs 112, so that the housing 1 can be fixed inside the hat P. The user can hold the brim of the hat P to wear the housing 1 normally, thereby improving the convenience of use.

[0057] When disassembling, the hat P is removed from the head, the bottom side of the inner surface of the hat P is moved to make the card slot P1 disengage from the plurality of legs 112, and then the housing 1 is taken out from the inner surface of the hat P.

[0058] Therefore, the supporting foot 112 and the card slot P1 are used in combination, so that the housing 1 can be disassembled and assembled, which is convenient for the user to clean the hat P and maintain the components inside the housing 1.

[0059] See attached Figure 1 -Attached Figure 7 The control unit 4 includes a circuit board 41, which is installed in the housing 1 and electrically connected to the lamp component 2 and the air supply component 3 to control the start and stop of the lamp component 2 and the air supply component 3.

[0060] Specifically, by presetting the corresponding control program on the control unit 4, the lamp component 2 and the air supply component 3 can be started and stopped at a scheduled time; in addition, by installing a signal receiving module on the circuit board 41, the start and stop of the lamp component 2 and the air supply component 3 can be controlled by a remote control device such as a mobile phone; since the relevant technology is relatively conventional in the electronic field, the specific circuit structure is not further elaborated in the present utility model.

[0061] See attached Figure 1 -Attached Figure 7 The control unit 4 also includes a sensing switch 42, which is installed on the inner wall of the sleeve cavity 110 and is electrically connected to the circuit board 41 to monitor whether the head enters the sleeve cavity 110, thereby controlling the start and stop of the lamp component 2 and the air supply component 3.

[0062] Specifically, when the sensing switch 42 detects that the head enters the sleeve cavity 110, the sensing switch 42 feeds back a signal to the circuit board 41, so that the circuit board 41 controls the lamp 2 and the air supply 3 to start; similarly, when the sensing switch 42 does not detect that the head enters the sleeve cavity 110, the sensing switch 42 does not feed back a signal to the circuit board 41, and the circuit board 41 controls the lamp 2 and the air supply 3 to turn off; therefore, the design of the sensing switch 42 can improve the degree of intelligence to further improve the convenience of use.

[0063] Furthermore, if the lighting component 2 and the air supply component 3 are to be started at different times, a temperature sensor (not shown in the figure) electrically connected to the circuit board 41 may be provided in the housing 1 to monitor the internal temperature of the hat P through the temperature sensor (not shown in the figure) to individually control the start and stop of the air supply component 3, so that the air supply component 3 is in a normally open state to reduce power consumption.

[0064] It should be noted that the technology of controlling the start and stop of parts such as the lamp 2 by using the induction switch 42 and the circuit board 41 is relatively common in the electronic field, so its specific working principle and circuit structure are not elaborated in detail in the utility model.

[0065] See attached Figure 1 -Attached Figure 7 The control unit 4 further includes a plurality of buttons 43, which are mounted on the housing 1 and are electrically connected to the circuit board 41 to control the start and stop of the lamp component 2 and the air supply component 3 respectively.

[0066] Specifically, when the induction switch 42 is not provided or the induction switch 42 is damaged, the user can manually press the corresponding button 43 to send a command to the circuit board 41 to control the start and stop of the lamp component 2 and the air supply component 3 respectively.

[0067] It should be noted that the technology of controlling the start and stop of parts such as the lamp 2 by using the button 43 and the circuit board 41 is relatively common in the electronic field, so its specific working principle and circuit structure are not elaborated in detail in the utility model.

[0068] See attached Figure 1 -Attached Figure 7 Regarding the power consumption of the lamp 2 and the air supply 3, the circuit board 41 can be directly connected to a mobile power supply or other power supply equipment for power supply. However, considering that this method is more troublesome, in the utility model, the control unit 4 also includes a battery 44 and a charging terminal 45. The battery 44 is installed in the shell 1, and the charging terminal 45 is installed on the shell 1. The circuit board 41 is electrically connected to the battery 44 and the charging terminal 45.

[0069] Specifically, when in use, the battery 44 can first supply power to the circuit board 41. According to the feedback information from the induction switch 42, the button 43, etc., the circuit board 41 can connect or disconnect the circuit with the lamp 2 and the air supply part 3, and then control the start and stop of the lamp 2 and the air supply part 3; when charging, use a charging cable to plug into the charging terminal 45, and the charging terminal 45 stores the electricity in the battery 44 through the circuit board 41 for the lamp 2 and the air supply part 3 to use.

[0070] It should be noted that the technology of using the battery 44 and the circuit board 41 to supply power to the lamp 2 and other parts, and the technology of charging the battery 44 through the charging terminal 45 and the circuit board 41, are relatively common in the electronic field, so the specific working principle and circuit structure are not elaborated in detail in the utility model.

[0071] See attached Figure 1 -Attached Figure 7 The button 43 and the charging terminal 45 are both located in the sleeve cavity 110 .

[0072] Specifically, under this design, the user can normally press the button 43 and connect the charging cable without taking the shell 1 out from the inner surface of the hat P, thereby improving the convenience of use.

[0073] It should also be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
