Description

Technical Field

[0001] This utility model relates to the field of physiotherapy equipment technology, and in particular to a treatment head and a far-infrared therapy device. Background Art

[0002] A far-infrared therapy device is a medical device that uses far-infrared rays to treat the human body. It primarily works by emitting far-infrared rays to heat human tissue, thereby promoting blood circulation, enhancing cell vitality, relieving muscle pain, and improving metabolism. This device is widely used in home healthcare, medical rehabilitation, and beauty care.

[0003] Existing far-infrared therapy devices mainly employ two heating methods: the first uses an infrared bulb as the heat source, utilizing the far-infrared rays emitted by the bulb to heat and treat the body; the second uses electric heating, such as ceramic heating plates or heating elements, which emit far-infrared rays through the heat generated after being powered on, thereby treating the body. The design of these devices needs to consider heating efficiency, uniform heat distribution, and heat dissipation.

[0004] However, existing heating source designs often fail to effectively prevent heat transfer to the non-heated areas of the outer casing, directly affecting the concentration of heat radiation and the therapeutic effect. Because the efficiency of heat radiation cannot be effectively controlled, some heat inevitably dissipates to the non-heated areas of the outer casing. This not only reduces the efficiency of heat utilization but also increases the temperature of the device's outer casing, potentially causing discomfort or even burns to the user during use. Utility Model Content

[0005] The main purpose of this invention is to provide a treatment head and a far-infrared therapy device, which aims to solve the problem of overheating of the treatment head's outer shell and improve the user experience.

[0007] The heating housing is housed inside the outer shell, and the outer side wall of the heating housing is spaced apart from the inner side wall of the outer shell to form a ventilation gap;

[0008] The outer wall of the outer casing is provided with a ventilation opening that connects to the ventilation gap;

[0009] The heating element is housed inside the heating housing;

[0010] The fan is located inside the outer casing and is positioned corresponding to the vent, and is used to guide outside air into the ventilation gap.

[0011] In one embodiment, the outer casing includes a base and an element plate, the base and the element plate are connected to enclose and form a heat insulation cavity, and the heating shell is housed in the heat insulation cavity; the base has the ventilation opening.

[0012] In one embodiment, the base includes a seat body and a guide ring disposed on the seat body. The base has a first through hole communicating with the heat insulation cavity. The guide ring is accommodated in the heat insulation cavity and disposed around the periphery of the first through hole. The bottom wall surface of the seat body has the ventilation opening.

[0013] The element plate includes a cover and a plug ring. The cover has a second through hole. The plug ring is located on the side of the cover near the first through hole and is arranged around the periphery of the second through hole. The plug ring is inserted into the guide ring.

[0014] In one embodiment, the outer side wall of the guide ring is provided with a first through hole; the outer side wall of the insertion ring is provided with a second through hole;

[0015] The base also includes a first connecting structure, which includes a first locking seat and a first locking member. The first locking seat is disposed on the base body and one end of the first locking seat passes through the first through hole to be located inside the guide ring. A first locking groove is provided on the side of the first locking seat away from the base body. One end of the first locking member passes through the first through hole and the second through hole and is locked in the first locking groove.

[0016] In one embodiment, the outer side wall of the base is provided with a third through hole communicating with the heat insulation cavity, and the base also includes a cable outlet tube, which is inserted into the third through hole to connect with the base.

[0017] In one embodiment, the cover has a plurality of spaced-apart perforated grooves.

[0018] In one embodiment, the outer casing further includes a dam body disposed on the base and housed in the heat insulation cavity, the dam body being arranged around the periphery of the vent to form a mounting groove;

[0019] The fan is housed within the mounting slot.

[0020] In one embodiment, the heating housing includes a heating base and a heat-conducting cover. A first mounting groove is formed inside the heating base, and a slot communicating with the first mounting groove is opened on one side of the heating base. The heat-conducting cover is accommodated in the first mounting groove and covers the slot. The heating element is disposed on the heating base and accommodated in the first mounting groove.

[0021] In one embodiment, a third through hole is provided in the bottom wall of the first mounting groove;

[0024] The treatment head provided by this utility model features a relatively sealed ventilation gap between the outer shell and the heating shell. This ventilation gap effectively isolates the heating shell and the outer shell, reducing the heat directly transferred to the outer shell. Furthermore, a fan on the outer shell guides cool outside air into the ventilation gap, thereby removing heat from the area surrounding the heating shell. The fan's operation also circulates the air within the ventilation gap, effectively absorbing the heat transferred from the heating shell and preventing heat accumulation in localized areas. In summary, on the one hand, the ventilation gap and fan design prevent heat loss from the heating shell to non-heated areas of the outer shell, improving heat utilization efficiency and directing more heat to the area requiring treatment. On the other hand, the surface temperature of the outer shell can be effectively controlled, enhancing the overall safety of the device. Users no longer need to worry about overheating of the treatment head's outer shell when using the far-infrared therapy device, thus providing a more comfortable and safer experience.

[0036] This utility model proposes a treatment head 100 for use in a far-infrared therapy device.

[0037] Please see Figures 1 to 4In one embodiment, the present invention provides a treatment head 100 for use in a far-infrared therapy device. The treatment head 100 includes an outer shell 4, a heating shell 1, a heating element 2, and a fan. The heating shell 1 is housed inside the outer shell 4, and the outer side wall of the heating shell 1 is spaced apart from the inner side wall of the outer shell 4 to form a ventilation gap. The outer side wall of the outer shell 4 has a ventilation opening 414 connected to the ventilation gap. The heating element 2 is housed inside the heating shell 1. The fan is located inside the outer shell 4 and is positioned corresponding to the ventilation opening 414 to guide outside air into the ventilation gap.

[0038] The treatment head 100 provided by this utility model features a relatively sealed ventilation gap between the outer shell 4 and the heating shell 1. This ventilation gap effectively isolates the heating shell 1 and the outer shell 4, reducing the heat directly transferred to the outer shell 4. Furthermore, a fan on the outer shell 4 guides cool outside air into the ventilation gap, thereby removing heat from the area surrounding the heating shell 1. The fan's operation also circulates the air within the ventilation gap, effectively absorbing the heat transferred from the heating shell 1 and preventing heat accumulation in localized areas. In summary, on the one hand, the ventilation gap and fan design prevent heat from the heating shell 1 from dissipating to non-heated areas of the outer shell 4, improving heat utilization efficiency and directing more heat to the area requiring treatment. On the other hand, the surface temperature of the outer shell 4 can be effectively controlled, enhancing the overall safety of the device. Users no longer need to worry about overheating of the treatment head 100's outer shell when using the far-infrared therapy device, thus providing a more comfortable and safer experience.

[0039] In one embodiment, the outer casing 4 includes a base 41 and an element plate 42. The base 41 and the element plate 42 are connected to enclose and form a heat insulation cavity, in which the heating shell 1 is housed. The base 41 has a vent 414. The design of the heat insulation cavity creates a heat insulation layer between the heating shell 1 and the outer casing 4, which helps to reduce the direct transfer of heat to the outer casing 4, thereby lowering the surface temperature of the outer casing 4. The element plate 42 ensures that the user will not directly contact the heating shell during use, improving the safety of the device. Through the vent 414 on the base 41 and the action of the fan, external cold air is drawn into the heat insulation cavity and comes into contact with the heating shell 1, carrying away heat and thus lowering the temperature of the heating shell 1, while also cooling the outer casing 4.

[0040] It should be noted that Element Plate 42 is a medical device that uses specific electromagnetic waves for treatment. This treatment plate is formulated with a scientifically blended formula based on various elements required by the human body. Under temperature, it generates oscillating signals carrying characteristic information of various elements. These signals, along with infrared rays, enter the human body and resonate with corresponding elements, thereby activating the activity of various enzymes, enhancing the absorption of deficient elements, adjusting the relative balance of elements in the body, inhibiting the increase of free radicals, and repairing microcirculation channels, thus improving the body's immune function and disease resistance.

[0041] In one embodiment, the base 41 includes a seat body 411 and a guide ring 412 disposed on the seat body 411. The base 41 has a first through hole communicating with the heat insulation cavity. The guide ring 412 is accommodated in the heat insulation cavity and is disposed around the periphery of the first through hole. The bottom wall surface of the seat body 411 has a vent 414. The element plate 42 includes a cover body 421 and a plug ring 422. The cover body 421 has a second through hole. The plug ring 422 is disposed on the side of the cover body 421 near the first through hole and is disposed around the periphery of the second through hole. The plug ring 422 is inserted into the guide ring 412. The design of the guide ring 412 and the insertion ring 422 ensures precise alignment between the element plate 42 and the base 41, improving assembly accuracy and convenience. The insertion ring 422, inserted into the guide ring 412, provides stable fixation for the element plate 42, preventing accidental movement or detachment during use and enhancing equipment safety. This design also allows for easy disassembly and reinstallation of the element plate 42, facilitating equipment maintenance and cleaning. In other embodiments, the element plate 42 and the base 41 can be connected using various structures, such as: screw fixing (screw holes are designed at corresponding positions on the base 41 and the element plate 42, and screws and nuts are used to secure them together); snap-fit ​​connection (snap-fits and slots are designed on the edges of the base 41 and the element plate 42, allowing the element plate 42 to be snap-fitted to the base 41 by pressing or sliding); and magnetic attraction (magnets are installed on the contact surfaces of the base 41 and the element plate 42, using magnetic force to attract them together, facilitating quick disassembly and installation).

[0042] In one embodiment, the outer wall of the guide ring 412 has a first through hole; the outer wall of the plug ring 422 has a second through hole; the base 41 further includes a first connecting structure, which includes a first locking seat 3 and a first locking member. The first locking seat 3 is disposed on the base body 411, and one end of the first locking seat 3 passes through the first through hole to be located inside the guide ring 412. A first locking groove is formed on the side of the first locking seat 3 away from the base body 411; one end of the first locking member passes through the first through hole and the second through hole and is locked in the first locking groove. During installation, the plug ring 422 is inserted into the guide ring 412, ensuring that the two are aligned. One end of the first locking member passes through the first through hole of the guide ring 412 and the second through hole of the plug ring 422, locking the first locking member in the first locking groove, thereby fixing the element plate 42 and the base 41. The first connecting structure makes the connection between the element plate 42 and the base 41 more secure and less prone to loosening. When the element plate 42 needs to be disassembled for maintenance or cleaning, simply loosen the first locking element; the operation is simple. The first locking element can be a bolt, screw, pin, or other similar fastener, the specific shape and size of which depend on the design of the equipment and the required fixing strength.

[0043] In one embodiment, the outer wall of the base 411 has a third through hole communicating with the heat insulation cavity. The base 41 also includes a cable outlet 413, which is inserted into the third through hole to connect with the base 411. The design of the heat insulation cavity and the cable outlet 413 effectively isolates the internal high-temperature area from the external environment, protecting the wires and wiring from heat damage. The use of the cable outlet 413 avoids direct exposure of the wires, reducing safety hazards caused by wire wear or contact with high temperatures. Furthermore, the design of the cable outlet 413 facilitates wire replacement and maintenance, allowing operation without completely disassembling the equipment.

[0044] In one embodiment, the cover 421 has a plurality of spaced-apart perforated slots. These slots increase the heat dissipation area of ​​the element plate 42, allowing heat to dissipate more effectively and reducing the surface temperature of the element plate 42, thus preventing burns to the user. The perforated design also reduces the overall weight of the element plate 42, making the treatment head 100 lighter and easier to operate and use.

[0045] In one embodiment, the outer casing 4 further includes a dam 53, which is disposed on the base 41 and housed within the insulation cavity. The dam 53 is arranged around the periphery of the vent 414 to form a mounting groove; the fan is housed within the mounting groove. Through the mounting groove formed by the dam 53, the fan can be stably mounted on the base 41, reducing vibration and noise and improving the overall stability of the equipment.

[0046] In one embodiment, the heating housing 1 includes a heating base 11 and a heat-conducting cover 12. A first mounting groove 111 is formed inside the heating base 11, and a slot communicating with the first mounting groove 111 is opened on one side of the heating base 11. The heat-conducting cover 12 is accommodated in the first mounting groove 111 and covers the slot. The heating element 2 is disposed on the heating base 11 and accommodated within the first mounting groove 111. Through the coverage of the heat-conducting cover 12, heat can be more evenly distributed on the heat-conducting cover 12, improving thermal efficiency, reducing energy loss, and ensuring that the device can safely and effectively generate far-infrared rays.

[0047] To enhance the connection stability between the heat-conducting cover 12 and the heating base 11, in one embodiment, a third through hole is provided on the bottom wall of the first mounting groove 111. The treatment head 100 also includes a second connecting structure, which includes a second locking seat and a second locking member. The second locking seat is located on the side of the heat-conducting cover 12 near the third through hole, and a second locking groove is provided on the second locking seat corresponding to the third through hole. One end of the second locking member passes through the third through hole and is locked in the second locking groove. The second connecting structure ensures the fixation between the heat-conducting cover 12 and the heating base 11, prevents relative movement, and maintains the stability of the heat conduction path. At the same time, the second connecting structure also facilitates future disassembly and maintenance, as only the second locking member needs to be loosened or tightened. The second locking member can be a bolt, screw, pin, or other similar fastener, and its specific shape and size depend on the design of the device and the required fixing strength.

[0048] This utility model also provides a far-infrared therapy device, including a treatment head 100. The specific structure of the treatment head 100 is as described in the above embodiments. Since the far-infrared therapy device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
