Description

Technical Field

[0001] This invention relates to the field of hair cutting equipment technology, and more specifically to a hair shaver with a cooling function. Background Technology

[0002] In existing technologies, hair shavers mainly rely on repeated relative friction between moving and stationary blades to cut hair. During long-term operation, the contact surfaces of the moving and stationary blades will generate a lot of heat due to frequent friction. As the overall temperature of the shaver head continues to rise, it will accelerate the wear of the shaver head and shorten its service life. On the other hand, the high temperature of the shaver head will directly contact the user's skin, causing a burning discomfort and possibly even low-temperature burns, affecting the user experience. Summary of the Invention

[0003] In view of this, the present invention provides a shaver with a cooling function.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A shaver with a cooling function includes a moving blade and a stationary blade. The moving blade is reciprocally mounted on the stationary blade. The stationary blade and the moving blade have corresponding stationary blade teeth and moving blade teeth on at least one side of the same side. A heat sink is provided between the moving blade and the stationary blade. One end of the heat sink is connected to the moving blade and / or the stationary blade. During the reciprocating motion of the moving blade, the heat sink is driven to move, thereby generating airflow to achieve cooling.

[0006] Preferably, the heat sink includes a heat sink body and a plurality of heat sink fins. The heat sink body has a centrally located shaft structure, and the heat sink fins are evenly distributed on the heat sink body with the central axis of the shaft structure as the center.

[0007] Preferably, the heat sink body is arranged in a semi-circular structure, the shaft structure is located at the center of the heat sink body, and the heat sink fins are spaced apart on the side of the shaft structure away from the heat sink body.

[0008] Preferably, a transmission rack is provided on the stationary or moving blade, and a gear structure is provided on the outer periphery of the heat sink body. The gear structure meshes with the transmission rack, and one end of the shaft structure is rotatably connected to the moving blade. During the reciprocating movement of the moving blade, the heat sink is driven to roll back and forth along the length direction of the transmission rack through the shaft structure. During the rolling of the heat sink, the heat sink fins fan the air to form an airflow, thereby achieving cooling.

[0009] Preferably, the transmission rack and the stationary cutter are separate structures. The stationary cutter is provided with a rack elastic positioning structure, which includes a positioning frame protruding from the stationary cutter and an elastic element disposed within the positioning frame. A rack movable opening is opened on one side of the positioning frame. The transmission rack is disposed within the positioning frame. One end of the transmission rack extends out of the positioning frame through the rack movable opening and abuts against the heat dissipation component. The two ends of the elastic element abut against the inner wall of the transmission rack and the positioning frame, respectively.

[0010] Preferably, the heat sink is connected to a moving blade and a stationary blade at both ends, the heat sink body is a circular sheet structure, the shaft structure is coaxial with the heat sink and is not clearly visible on one end face of the heat sink body, and the heat sink fins are radially distributed at equal intervals on the shaft structure with the shaft structure as the center and are connected to the heat sink body.

[0011] Preferably, an eccentric transmission end is provided on the end face of the heat sink away from the shaft structure. The eccentric transmission end is eccentrically positioned with respect to the center of the heat sink body. The eccentric transmission end is connected to the moving blade. During the reciprocating movement of the moving blade, the heat sink will be driven to rotate eccentrically around the shaft structure through the eccentric transmission end, thereby driving the heat sink on the shaft structure to rotate synchronously.

[0012] Preferably, the end of the shaft structure away from the heat sink body extends to form a stationary blade connection end coaxially arranged with the shaft structure, and a stationary blade rotating hole corresponding to the stationary blade connection end is opened on the stationary blade, and the stationary blade connection end extends into the stationary blade rotating hole and is rotatably connected to the stationary blade.

[0014] Preferably, the heat sink on the heat sink is at least partially close to the stationary blade tooth portion, and the heat sink 6 cools the stationary blade tooth portion by driving the heat sink 6 to fan out after the heat sink rotates.

[0015] The beneficial effects of this invention are as follows: During the reciprocating movement of the moving blades to trim the hair, the heat sink moves synchronously, causing the heat sink to generate directional airflow that directly acts on the area where the blades generate heat through friction. This promptly removes the heat generated by the relative friction between the moving and stationary blades, preventing the blade area temperature from rising rapidly after prolonged use and avoiding burning discomfort for the user during shaving. It also slows down the aging and deformation of plastic components and metal blades due to high temperatures, extending the overall lifespan of the shaver. Moreover, this structure does not require additional independent cooling components such as motors and fans, thus not significantly increasing the overall size and production cost of the shaver, nor consuming additional electricity. The overall structure is simple and compatible with existing shaver manufacturing processes. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The present invention will now be further described with reference to the accompanying drawings.

[0031] This invention provides the following technical solution:

[0032] As attached Figure 1-12 As shown, the present invention discloses a shaver with a cooling function, including a moving blade 1 and a stationary blade 2. The moving blade 1 is reciprocally mounted on the stationary blade 2. The stationary blade 2 and the moving blade 1 have corresponding stationary blade teeth 3 and moving blade teeth 4 on at least one side of the same side. A heat sink 5 is provided between the moving blade 1 and the stationary blade 2. One end of the heat sink 5 is connected to the moving blade 1 and / or the stationary blade 2. During the reciprocating motion of the moving blade 1, the heat sink 5 is driven to move, thereby generating airflow to achieve cooling. Specifically, in this design, as the moving blade 1 reciprocates to trim the hair, it drives the heat sink 5 to move synchronously. The heat sink 5 generates directional airflow with the movement of the moving blade, which directly acts on the area where the blade friction generates heat. This promptly removes the heat generated by the relative friction between the moving blade 1 and the stationary blade 2, preventing the blade area temperature from rising rapidly after prolonged use. This prevents users from experiencing burning discomfort during shaving and also slows down the aging and deformation of plastic components and metal blades due to high temperatures, extending the overall lifespan of the shaver. Moreover, this structure does not require additional independent cooling components such as motors and fans, thus not significantly increasing the overall size and production cost of the shaver, nor consuming additional electricity. The overall structure is simple and compatible with existing shaver manufacturing processes.

[0033] Reference Appendix Figure 1-12The heat sink 5 includes a heat sink body 51 and a plurality of heat sink fins 6. A shaft structure 7 is centrally located on the heat sink body 51, and the heat sink fins 6 are evenly distributed on the heat sink body 51 with the central axis of the shaft structure 7 as the center. Specifically, in this embodiment, the plurality of heat sink fins 6 evenly distributed on the heat sink 5 with the central axis of the shaft structure 7 as the center can significantly increase the contact area between the heat sink 5 and the air, accelerate the transfer and dissipation of heat, thereby effectively improving the heat dissipation efficiency of the heat sink 5 and ensuring that the heat generated during the operation of the equipment can be promptly discharged and dissipated into the external environment, maintaining the stability of the internal temperature of the equipment.

[0034] Reference Appendix Figure 2-5 The heat sink body 51 is semi-circular in shape, the shaft structure 7 is located at the center of the heat sink body 51, and the heat sink fins 6 are spaced apart on the side of the shaft structure 7 away from the heat sink body 51. Specifically, in this embodiment, the semi-circular structure of the heat sink body 51 increases the contact area with air, thereby improving heat dissipation efficiency; the shaft structure 7, located at the center of the heat sink body 51, ensures that the heat sink body 51 rotates smoothly around the shaft structure 7, guaranteeing the stability of the heat dissipation process; the heat sink fins 6, spaced apart on the side of the shaft structure 7 away from the heat sink body 51, can form convection during rotation, further accelerating the heat dissipation rate.

[0035] Reference Appendix Figure 2-5The stationary blade 2 or the moving blade 1 is provided with a transmission rack 8, and the heat sink body 51 is provided with a gear structure 9 on its outer periphery. The gear structure 9 is meshed with the transmission rack 8. One end of the shaft structure 7 is rotatably connected to the moving blade 1. During the reciprocating movement of the moving blade 1, the heat sink 5 is driven to reciprocate along the length direction of the transmission rack 8 through the shaft structure 7. During the rolling of the heat sink 5, the heat sink 6 fanns the air to form an airflow, thereby achieving cooling. Specifically, in this embodiment, when the moving blade 1 reciprocates between the stationary blades 2, the moving blade 1 drives the shaft structure 7, which is rotatably connected to it, to reciprocate synchronously. The shaft structure 7 then pushes the heat sink body 51 so that the gear structure 9 on its outer periphery remains engaged with the transmission rack 8 and rolls along the length of the transmission rack 8. During the rolling process, the heat sink 5's own heat sink 6 continuously generates relative motion with the surrounding air as it rolls. The fanning effect of the heat sink 6 carries away the heat from the working area of ​​the tool with the airflow, thereby achieving real-time cooling of the moving blade 1 and the stationary blades 2. Since the meshing transmission between the gear structure 9 and the transmission rack 8 has a definite transmission ratio, the rolling speed of the heat sink 5 is matched with the reciprocating speed of the moving blade 1, ensuring that the heat dissipation efficiency of the heat sink 5 changes synchronously with the working intensity of the tool, avoiding insufficient or excessive heat dissipation. At the same time, the rotatable connection design between the shaft structure 7 and the moving blade 1 allows the heat sink 5 to roll freely while moving with the moving blade 1, reducing mechanical resistance during transmission and ensuring the smoothness of the tool's cutting action and the stability of the heat sink 5's rotation.

[0036] Reference Appendix Figure 2-5The transmission rack 8 and the stationary cutter 2 are arranged in a separate structure. The stationary cutter 2 is provided with a rack elastic positioning structure. The rack elastic positioning structure includes a positioning frame portion 10 protruding from the stationary cutter 2 and an elastic element 11 disposed in the positioning frame portion 10. A rack movable opening 12 is opened on one side of the positioning frame portion 10. The transmission rack 8 is disposed in the positioning frame portion 10. One end of the transmission rack 8 extends out of the positioning frame portion 10 through the rack movable opening 12 and abuts against the heat sink 5. The two ends of the elastic element 11 abut against the inner wall of the transmission rack 8 and the positioning frame portion 10, respectively. Specifically, in this embodiment, the transmission rack 8 and stationary cutter 2 are designed as separate units, which reduces the machining accuracy requirements of both, facilitates separate manufacturing and assembly, and improves production efficiency. The rack elastic positioning structure on the stationary cutter 2 can provide stable guidance and limit for the transmission rack 8 through the positioning frame 10, ensuring that the transmission rack 8 will not deviate during movement and guaranteeing the accuracy of transmission. The elastic element 11 inside the positioning frame 10 has its two ends abutting against the inner wall of the transmission rack 8 and the positioning frame 10, respectively. It can continuously apply elastic force to the transmission rack 8 using its own elasticity, so that one end of the transmission rack 8 always extends out of the positioning frame 10 through the rack movable opening 12 and tightly abuts against the heat sink 5, avoiding gaps between the transmission rack 8 and the heat sink 5 that would affect the transmission effect. At the same time, during transmission, the elastic element 11 can also play a buffering role, reducing rigid collisions between the transmission rack 8 and the inner wall of the positioning frame 10, reducing component wear, and extending service life.

[0037] Reference Appendix Figure 6-9In another embodiment, the heat sink 5 is connected to a moving blade 1 and a stationary blade 2 at both ends, respectively. The heat sink body 51 is a circular sheet structure. The shaft structure 7 is coaxially arranged with the heat sink body 51 on one side end face of the heat sink body 51. The heat sink fins 6 are radially distributed at equal intervals on the shaft structure 7 and connected to the heat sink body 51. Specifically, in this embodiment, the moving blade 1 and the stationary blade 2 are connected to both ends of the heat sink body 51, so that the heat generated by the moving blade 1 and the stationary blade 2 during operation can be quickly transferred to the heat sink 5. The circular sheet structure of the heat sink body 51 increases the contact area with air, which is beneficial for heat dissipation. The coaxial arrangement of the shaft structure 7 with the heat sink body 51 on one side end face of the heat sink body 51 ensures a stable connection and coaxiality between the shaft structure 7 and the heat sink body 51, avoiding vibration and uneven heat distribution caused by eccentricity. Heat sinks 6 are radially distributed at equal intervals on the shaft structure 7 with the shaft structure 7 as the center and are connected to the heat sink body 51. This radially distributed heat sink 6 further increases the heat dissipation area. At the same time, the equal interval ensures that heat can be evenly diffused from the shaft structure 7 and the heat sink 5 to the surrounding air, improving the overall heat dissipation efficiency. This effectively reduces the working temperature of the moving blade 1 and the stationary blade 2, ensuring the stability of their working performance and service life.

[0038] Reference Appendix Figure 6-9 An eccentric transmission end 13 is provided on the end face of the heat sink body 51 away from the shaft structure 7. The eccentric transmission end 13 is eccentrically positioned with respect to the center of the heat sink body 51. The eccentric transmission end 13 is connected to the moving blade 1. During the reciprocating movement of the moving blade 1, it drives the heat sink 5 to rotate eccentrically around the shaft structure 7 via the eccentric transmission end 13, thereby driving the heat sink 6 on the shaft structure 7 to rotate synchronously. Specifically, in this embodiment, when the moving blade 1 moves, it drives the eccentric transmission end 13 to move synchronously. Since the eccentric transmission end 13 is eccentrically positioned with respect to the heat sink body 51, the movement of the eccentric transmission end 13 is converted into the reciprocating oscillation of the heat sink body 51 around the shaft structure 7. Through the reciprocating oscillation of the heat sink body 51, the airflow speed around the heat sink body 51 can be accelerated, thereby improving the heat dissipation efficiency of the heat sink 5.

[0039] Reference Appendix Figure 6-9The shaft structure 7 extends from the end furthest from the heat sink body 51 to form a stationary blade connecting end 14 coaxially arranged with the shaft structure 7. A stationary blade rotating hole 15 corresponding to the stationary blade connecting end 14 is formed on the stationary blade 2. The stationary blade connecting end 14 extends into the stationary blade rotating hole 15 and is rotatably connected to the stationary blade 2. Specifically, in this embodiment, the shaft structure 7 and the stationary blade connecting end 14 are integrally formed. The outer diameter of the stationary blade connecting end 14 is smaller than the outer diameter of the shaft structure 7, forming a stepped transition. The diameter of the stationary blade rotating hole 15 matches the outer diameter of the stationary blade connecting end 14. After the stationary blade connecting end 14 extends into the stationary blade rotating hole 15, its outer circumferential surface fits against the inner wall surface of the stationary blade rotating hole 15, achieving stable rotation of the stationary blade 2 around the stationary blade connecting end 14.

[0040] Reference Appendix Figure 10-12 In another embodiment, the transmission rack 8 and the moving blade 1 are integrally formed. The transmission rack 8 protrudes from the end face of the moving blade 1 near the stationary blade 2. The moving blade 1 has a heat sink connecting groove 16, and the stationary blade 2 has a heat sink rotating hole 17. The heat sink 5 is provided with an upper connecting end 19 and a lower connecting end 20 corresponding to the heat sink connecting groove 16 and the heat sink rotating hole 17, respectively. The upper connecting end 19 and the lower connecting end 20 extend into the heat sink connecting groove 16 and the heat sink rotating hole 17, respectively, and connect with the moving blade 1 and the stationary blade 2. Specifically, in this embodiment, the integral molding of the transmission rack 8 and the moving blade 1 enhances the connection strength between them, ensuring that there is no relative displacement during power transmission and improving the stability and reliability of the transmission. The transmission rack 8 protrudes from the end face of the moving blade 1 near the stationary blade 2, making its placement more reasonable and avoiding excessive space occupation, thus contributing to the compactness of the overall structure. A heat sink connection groove 16 is provided on the moving blade 1, providing an installation position for the upper connection end 19 of the heat sink 5, enabling a stable connection between the heat sink 5 and the moving blade 1. A heat sink rotating hole 17 is provided on the stationary blade 2, for... The lower connecting end 20 of the heat sink 5 provides a rotation support point, allowing the heat sink 5 to rotate around the lower connecting end 20. The heat sink 5 is provided with an upper connecting end 19 and a lower connecting end 20 corresponding to the heat sink connecting groove 16 and the heat sink rotating hole 17, respectively. The upper connecting end 19 and the lower connecting end 20 extend into the heat sink connecting groove 16 and the heat sink rotating hole 17, respectively, and connect to the moving blade 1 and the stationary blade 2. In this way, when the moving blade 1 moves relative to the stationary blade 2, the heat sink 5 can rotate accordingly with the movement of the moving blade 1, thereby dissipating the heat generated by the moving blade 1 and the stationary blade 2 during operation through the heat sink 5 in a timely manner, improving the overall heat dissipation effect and ensuring the normal operation of the equipment.

[0041] Reference Appendix Figure 1-12The heat sink 6 on the heat sink 5 is at least partially close to the stationary blade teeth 3. After the heat sink 5 rotates, it drives the heat sink 6 to fan and cool the stationary blade teeth 3. Specifically, in this embodiment, the stationary blade teeth 3 and the moving blade teeth 4 are each composed of several spaced-apart stationary and moving blade teeth. The hair is trimmed after being bitten by the stationary and moving blade teeth. During the trimming process, most of the frictional heat is concentrated at the tooth position. The heat sink 6 is at least partially close to the stationary blade teeth, which can directly cool the area with the most concentrated heat generation, maximize the cooling effect, and prevent the temperature of the teeth from rising and being transferred to the gripping position. It directly removes heat from the heat source, resulting in higher cooling efficiency.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
