Description

Technical Field

[0001] This application relates to the field of massage equipment, and in particular to massage heads and fascia guns with hot and cold switching control. Background Technology

[0002] Fascia guns, as highly efficient muscle relaxation tools, have been widely used in post-exercise muscle recovery and daily massage. However, traditional fascia gun heads mostly only have a single vibration massage function, which cannot meet users' diverse treatment needs. With the advancement of technology and people's increasing demand for health, alternating hot and cold therapy, due to its unique advantages such as promoting blood circulation, accelerating inflammation reduction, and relieving pain, has been widely used in the medical and rehabilitation fields.

[0003] Initially, the back cover was used to create hot and cold zones, but because it was a static structure, the experience was not good. Therefore, manufacturers designed the massage head to achieve both hot and cold compresses and impact massage. Currently, most solutions use semiconductor cooling chips and fans for heat dissipation, which can achieve a certain amount of energy transfer and hot and cold switching. However, the process of cooling with a fan will cause energy loss, and apart from solving the heat dissipation problem, it cannot further control the hot and cold of the massage head. Utility Model Content

[0004] The purpose of this invention is to provide a massage head with heat and cold conversion control, which aims to solve the heat dissipation problem of the massage head while also controlling the heat and cold of the massage head.

[0005] This utility model discloses a massage head with hot and cold conversion control, the massage head comprising:

[0006] The working head includes a first housing, a temperature-sensitive contact pad, and a semiconductor cooling chip. The first housing is provided with a first mounting part and a second mounting part. The first mounting part is embedded with the temperature-sensitive contact pad that contacts the skin, and the second mounting part is embedded with the semiconductor cooling chip. The temperature-sensitive contact pad is in contact with the semiconductor cooling chip.

[0007] The heat dissipation section includes a second housing and a water cooling assembly. The first housing and the second housing are snapped together to form a receiving cavity. The water cooling assembly is disposed inside the receiving cavity and abuts against the mounting surface of the semiconductor cooling chip on the second mounting section.

[0008] The connector includes a third housing and a power conversion assembly. The power conversion assembly is located inside the cavity of the third housing. One end of the third housing abuts against the inner wall of the second housing, and the other end is fixed with the power conversion assembly to connect to an external power source. The power conversion assembly is electrically connected to the water-cooling assembly and the semiconductor refrigeration chip, respectively.

[0009] Optionally, the water-cooling assembly has a heat-conducting end face that contacts the semiconductor cooling chip and a plurality of communicating internal channels, wherein the internal channels are filled with high-performance phase change material.

[0010] Optionally, the water-cooling assembly further includes a micropump electrically connected to the power conversion assembly to drive the high-performance phase change material to circulate within the internal channel.

[0011] Optionally, the second housing includes a housing base and a top cover, with the two ends of the housing base respectively engaging with the first housing and the top cover to form the receiving cavity, and the top cover being sleeved on one end of the third housing that extends into the second housing.

[0012] Optionally, the housing has heat sinks perpendicular to the mating plane and heat dissipation slots leading to the outside, and a plurality of the heat sinks surround to form a support frame, which cooperates with the first housing to fix the water cooling assembly.

[0013] Optionally, a cooling fan facing the water-cooling assembly is provided at the center of the support frame.

[0014] Optionally, the second housing further includes a control board, which is snapped between the upper cover and the end of the third housing that extends into the second housing. The control board integrates a control chip that is electrically connected to the power conversion component, the water cooling component, and the thermoelectric cooler.

[0015] Optionally, the third housing further includes an anti-slip component, which is fitted onto the outside of the third housing and has a plurality of raised anti-slip strips on its surface.

[0016] Optionally, the surface material of the temperature-sensitive contact patch includes at least one of the following types: metal, ceramic, or glass.

[0017] This utility model also proposes a fascia gun, which includes a gun body and a massage head with hot and cold switching control as described above, the massage head being mounted on the gun body.

[0018] This invention discloses a massage head with heat and cold conversion control. Through the combination of a built-in temperature-sensing contact plate and a semiconductor cooling chip, the massage head can sense and respond to skin temperature in real time, thereby intelligently adjusting the heat and cold output to adapt to the massage needs and skin temperatures of different users. The direct contact between the water-cooling component and the semiconductor cooling chip greatly enhances heat dissipation efficiency, thus helping to maintain the stable performance of the semiconductor cooling chip during long-term operation, extending its service life, and reducing the risk of overheating. The water-cooling component can absorb or release heat and carry this heat to other parts for heat dissipation or heating, thereby realizing the heat and cold conversion control of the massage head. The massage head achieves a high degree of integration through the snap-fit ​​design of the first, second, and third housings, making the overall structure more compact, easy to carry and use, and effectively reducing production costs and assembly complexity.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model proposes a massage head with hot and cold switching control, comprising:

[0031] The working head 1 includes a first housing 11, a temperature-sensitive contact piece 12, and a semiconductor cooling chip 13. The first housing 11 is provided with a first mounting part 111 and a second mounting part 112. The first mounting part 111 is embedded with the temperature-sensitive contact piece 12 that contacts the skin, and the second mounting part 112 is embedded with the semiconductor cooling chip 13. The temperature-sensitive contact piece 12 is in contact with the semiconductor cooling chip 13.

[0032] The heat dissipation part 2 includes a second housing 21 and a water cooling assembly 22. The first housing 11 is snapped into the second housing 21 to form a receiving cavity. The water cooling assembly 22 is disposed inside the receiving cavity. The water cooling assembly 22 abuts against the mounting surface of the semiconductor cooling chip 13 on the second mounting part 112.

[0033] The plug-in part 3 includes a third housing 31 and a power conversion component 32. The power conversion component 32 is located in the cavity of the third housing 31. One end of the third housing 31 abuts against the inner wall of the second housing 21, and the other end is fixed with the power conversion component 32 to plug in an external power source. The power conversion component 32 is electrically connected to the water cooling component 22 and the semiconductor refrigeration chip 13, respectively.

[0034] In this embodiment, the massage head mainly consists of a working head 1, a heat dissipation part 2, and a plug-in part 3. The working head 1 is the core part of the massage head, including a first housing 11, a temperature-sensing contact piece 12, and a semiconductor cooling chip 13. The first housing 11 serves as a support structure, and its surface is provided with two mounting parts: a first mounting part 111 and a second mounting part 112. The temperature-sensing contact piece 12 is embedded in the first mounting part 111, and it directly contacts the user's skin to sense skin temperature. The semiconductor cooling chip 13 is embedded in the second mounting part 112, and it is in close contact with the temperature-sensing contact piece 12. Based on the temperature changes sensed by the temperature-sensing contact piece 12, the semiconductor cooling chip 13 can automatically adjust its cooling or heating state to achieve temperature regulation of the massage head.

[0035] The heat dissipation section 2 includes a second housing 21 and a water-cooling assembly 22. The second housing 21 is snapped into the first housing 11, forming a receiving cavity between them. The water-cooling assembly 22 is installed in the receiving cavity and directly abuts against the mounting surface of the semiconductor cooling chip 13 on the second mounting section 112 for effective heat dissipation or heating to achieve rapid temperature changes.

[0036] The connector 3 serves as a bridge connecting the massage head to an external power source, primarily consisting of a third housing 31 and a power conversion assembly 32. One end of the third housing 31 abuts against the inner wall of the second housing, while the other end is fixed with the power conversion assembly 32. Located within the cavity of the third housing 31, the power conversion assembly 32 converts the external power source into DC power or AC power of a specific voltage level required by various parts of the massage head. Simultaneously, the power conversion assembly 32 is also electrically connected to the water-cooling assembly and the thermoelectric cooler 13, providing them with necessary power support. The shape and size of the third housing 31 are selected based on the overall design of the massage head and the connection requirements of the external power source. The third housing 31 incorporates internal snap-fit ​​positions that match the external power source, ensuring a secure connection between the massage head and the external power source.

[0037] In this embodiment, the temperature-sensing contact 12 can be one of metal, ceramic or glass. Different material selections will directly affect the thermal response speed, thermal conductivity and durability of the temperature-sensing contact 12, and can be selected according to the actual situation. The semiconductor cooling chip 13, also known as a thermoelectric cooling chip, is a device that uses the Peltier effect to achieve cooling or heating effects. Its working principle is based on the thermoelectric effect, that is, when direct current passes through two different semiconductor materials (usually P-type and N-type), heat absorption and heat release will be generated at the two ends of the thermocouple respectively.

[0038] like Figure 2 As shown, in some embodiments, the water-cooling assembly 22 consists of a heat-conducting end face and several interconnected internal channels. The heat-conducting end face is in close contact with the thermoelectric cooler 13 to ensure that heat can be efficiently transferred from the thermoelectric cooler 13 to the water-cooling assembly 22; the internal channels form a circulation path for the coolant, used to carry away heat from the heat-conducting end face or transfer heat to the heat-conducting end face for the control of the hot and cold conversion of the massage head.

[0039] The water-cooling assembly 22 also includes a micro-pump, which is electrically connected to the power conversion assembly 32 to drive the high-performance phase change material to circulate within the internal channels. The micro-pump is positioned to ensure uniform and efficient flow of coolant through contact with the semiconductor cooling chip 13. Driven by the micro-pump, the phase change material continuously absorbs or releases heat from its heat-conducting end face and carries this heat to other parts for heat dissipation or heating, thereby achieving temperature control of the massage head.

[0040] like Figure 2 and Figure 4 As shown, in some embodiments, the second housing 21 mainly consists of a base 211 and a top cover 212. The base 211 is the main supporting structure of the heat dissipation part 2, and the top cover 212 is used to seal the top of the accommodating cavity, protecting the internal components from external interference and damage. The accommodating cavity is a closed space formed by the base 211, the top cover 212, and the first housing 11, used to accommodate components such as the water-cooling component 22 and the semiconductor cooling chip 13. The top cover 212 is also fitted onto the end of the third housing 31 that extends into the second housing 21, ensuring a good connection between the third housing 31 and its internal power conversion component 32 and the second housing 21, further enhancing the structural stability.

[0041] The housing 211 has a heat sink 23 formed inside, perpendicular to the mating plane. By increasing the heat exchange area between the housing 211 and the air, and through its vertical arrangement, heat can be transferred more effectively from the inside to the external environment, thereby improving heat dissipation efficiency. The heat sink 23 is typically made of metal to have good thermal conductivity, enabling it to quickly transfer the heat generated inside the massage head to the heat sink 23. Figure 5As shown, in addition to the heat sink 23, the housing 211 also has heat dissipation slots 2111 formed inside, leading to the outside. The function of the heat dissipation slots 2111 is to allow air to circulate between the heat sinks 23, thereby carrying away the heat on the heat sinks 23, ensuring that the air can flow smoothly over the heat sinks 23, while avoiding interference with other parts of the massage head. Among them, several heat sinks 23 form a support frame, which provides additional support for the water-cooling component 22. Through cooperation with the first housing 11, the support frame can stabilize the position of the water-cooling component 22 in the accommodating cavity, preventing it from moving or vibrating during operation due to the vibration of the massage head, thereby ensuring the overall performance and stability of the massage head.

[0042] Furthermore, a cooling fan 24 is positioned at the center of the support frame, facing the water-cooling assembly 22. The cooling fan 24 generates airflow to accelerate the airflow around the water-cooling assembly 22, thereby removing more heat. The cooling fan 24, together with the heat sink 23 and the heat dissipation slots 2111, constitute a new heat dissipation system outside the water-cooling assembly 22. The heat sink 23 improves heat dissipation efficiency by increasing its surface area, the heat dissipation slots 2111 provide additional heat exhaust channels, and the cooling fan 24 accelerates heat transfer and dissipation by generating airflow. The synergistic effect of these three components makes the massage head even more effective in heat dissipation, further ensuring stable performance under various operating conditions.

[0043] like Figure 5 As shown, in some embodiments, the second housing 21 further includes a control board 213. The control board 213 integrates a control chip electrically connected to the power conversion component 32, the water cooling component 22, and the thermoelectric cooler 13, for controlling the heat dissipation and heat absorption of the water cooling component 22 and the cooling and heating of the thermoelectric cooler 13. The control board 213 is snapped between the upper cover 212 and the end of the third housing 31, and its edge position has good sealing performance to ensure that it can effectively seal the gap and prevent moisture, dust, and other impurities from entering the plug-in part 3 and the inside of the control chip, ensuring the safe and stable operation of the internal components of the plug-in part 3 and the control chip, thereby avoiding performance degradation or failure caused by impurities entering. In addition, the control board 213 also helps to improve the overall structural strength of the massage head. By increasing the number and tightness of the connection points, the control board 213 makes the connection between the second housing 21 and the third housing 31 more stable, thereby enhancing the durability and reliability of the massage head.

[0044] like Figure 5As shown, in some embodiments, the anti-slip component 311 is sleeved on the third housing 31. The anti-slip component 311 is also provided with a number of raised anti-slip strips at the position where it contacts the outside. The raised anti-slip strips can increase the friction between the anti-slip component and the user's hand, thereby reducing the possibility of slippage when the user rotates the anti-slip component. This makes the installation, disassembly or adjustment of the massage head smoother and reduces the risk of the massage head becoming loose or damaged due to improper operation.

[0045] In summary, the massage head with heat and cold conversion control disclosed in this utility model, through the combination of the built-in temperature-sensing contact plate 12 and the semiconductor cooling plate 13, allows the massage head to sense and respond to skin temperature in real time, thereby intelligently adjusting the heat and cold output to adapt to the massage needs and skin temperatures of different users; the water-cooling component 22, through its internal heat-conducting end face and connected internal channels, as well as the filled high-performance phase change material, can absorb or release heat and carry this heat to other parts for heat dissipation or heating, thereby realizing the heat and cold conversion control of the massage head; the first housing 11, the second housing 21, and the third housing 31 are connected by a snap-fit ​​method, forming a compact and easily disassembled structure, without... Not only does it facilitate assembly and maintenance, but it also reduces production costs; the design of the heat sink 23 and heat dissipation slots 2111 in the second housing 21 increases the heat dissipation area and improves heat dissipation efficiency, and also enhances the structural stability through the support frame formed by the heat sink 23; the arrangement of the heat sink 23, heat dissipation slots 2111 and cooling fan 24 in the second housing 21 can further accelerate heat dissipation, which helps maintain the stable performance of the semiconductor cooling chip 13 under long-term operation, extends its service life, and reduces the risk of overheating; the temperature-sensitive contact pad 12 is made of materials such as metal, ceramic or glass, providing different tactile sensations and temperature conduction properties to meet the needs and preferences of different users.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
