Description

Technical Field

[0001] The invention relates to the technical field of physical therapy apparatus, in particular to a treatment head and a far-infrared treatment apparatus. Background Art

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

[0003] The existing far-infrared therapeutic device mainly includes two heating schemes: the first is to use infrared bulbs as heating sources, and use the far-infrared rays emitted by infrared bulbs to heat the human body for treatment; the second is to use electric heating methods, such as ceramic heating plates or heating elements, to emit far-infrared rays through the heat generated after power is turned on, and then treat the human body. The design of these therapeutic devices needs to consider heating efficiency, heat distribution uniformity and heat dissipation of the equipment.

[0004] However, the existing design of heating sources often fails to effectively isolate heat from being transferred to the non-heating area of ​​the shell surface, which directly affects the concentration of thermal radiation and the therapeutic effect. Since the efficiency of thermal radiation cannot be effectively controlled, part of the heat is inevitably dissipated to the non-heating area of ​​the device shell, which not only reduces the utilization efficiency of thermal energy, but also increases the temperature of the device shell, which may cause users to feel uncomfortable or even burn during use. Summary of the invention

[0005] The main purpose of the present invention is to provide a treatment head and a far-infrared treatment device, which are designed to isolate heat from being transferred to the shell surface of non-heating areas to improve user experience.

[0010] A fan is arranged in the heat-insulating cavity and corresponding to the vent, and is used for guiding external air to enter the vent.

[0011] In one embodiment, the outer shell includes a base and an element plate, the base and the element plate are connected to enclose and form a heat-insulating cavity, and the heat-generating shell is accommodated in the heat-insulating cavity; the base is provided with the vent.

[0012] In one embodiment, the base includes a base body and a guide ring disposed on the base body, the base is provided with a first through hole connected to the heat insulation cavity, the guide ring is accommodated in the heat insulation cavity and is disposed around the periphery of the first through hole; the bottom wall surface of the base body is provided with the vent;

[0013] The element plate includes a cover body and a plug-in ring. The cover body is provided with a second through hole. The plug-in ring is arranged on a side of the cover body close to the first through hole and around the periphery of the second through hole. The plug-in ring is plugged into the guide ring.

[0014] In one embodiment, the outer wall of the guide ring is provided with a first through hole; the outer wall of the plug-in 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 piece. The first locking seat is arranged on the seat body and one end of the first locking seat is passed through the first through hole to be located on the inner side of the guide ring. A first locking groove is opened on the side of the first locking seat away from the seat body; one end of the first locking piece 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 wall of the seat body is provided with a third through hole communicating with the heat insulation cavity, and the base further comprises an outlet pipe, and the outlet pipe is inserted into the third through hole to be connected with the seat body.

[0017] In one embodiment, a heat-conducting protrusion is formed on a side of the heat-conducting cover close to the heat-generating element and corresponding to the heat-generating element, a heat-conducting groove is formed on a side of the heat-conducting protrusion facing away from the heat-conducting cover, and the heat-conducting groove and the bottom wall of the first mounting groove are combined to form a heat-conducting cavity; the heat-generating element is accommodated in the heat-conducting cavity.

[0018] In one embodiment, the treatment head also includes a second connection structure, which includes a clamping column and a clamping seat, the clamping seat is provided with a clamping groove, one of the clamping column and the clamping seat is arranged on the heat-conductive cover and adjacent to the heat-conductive protrusion, and the other of the clamping column and the clamping seat is arranged on the heating base, and the clamping column is inserted into the clamping groove to connect the heat-conductive cover and the heating base.

[0022] The treatment head designed in the present invention includes a heating base, a heating element and a heat-conducting cover. The first mounting groove formed inside the heating base is used to accommodate the heating element, while the heat-conducting cover covers part of the groove and forms a first thermal insulation gap between the heat-conducting cover and the groove wall of the heating base. Since the heat-conducting cover covers part of the groove of the heating element and the existence of the first thermal insulation gap, there is no direct contact between the heating base and the heat-conducting cover. Heat is mainly transferred to the heat-conducting cover by thermal radiation rather than directly by heat conduction, so that the thermal radiation can be more concentratedly directed to the treatment area, reducing the transfer of heat to the non-heating area (mainly the area not used for directly emitting heat for treatment, such as the side wall of the heating base) of the outer shell surface, thereby improving the utilization efficiency of thermal energy. In addition, air or other materials with low thermal conductivity efficiency (such as asbestos or organic thermal insulation materials) can be used as thermal insulation media between the first thermal insulation gap, thereby further reducing the shell temperature of the non-heating area on the front side of the treatment head. In addition, in order to prevent the shell temperature of the non-heating area on the rear side from being too high, a relatively sealed ventilation gap is designed between the outer shell and the heating shell, which effectively isolates the heating shell and the outer shell, reducing the heat directly transferred to the outer shell. In addition, a fan is arranged on the outer shell to guide the cold air from the outside into the ventilation gap, thereby taking away the heat around the heating shell, and the operation of the fan can make the air in the ventilation gap flow, thereby effectively absorbing the heat transferred from the heating shell, avoiding the accumulation of heat in the local area, and thus making the heat of the heating shell no longer dissipate to the non-heating area of ​​the outer shell, and the utilization efficiency of thermal energy is improved, and more heat is directed to the area that needs treatment. In summary, the treatment head provided by the present invention optimizes the heat transfer path of the front and rear sides of the treatment head by setting the first insulation gap and the ventilation gap, which not only reduces the unnecessary loss of heat, but also significantly improves the heating efficiency and heat distribution uniformity of the far-infrared therapeutic device, ensuring the safety of the equipment and the comfort experience of the user.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0037] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] The invention provides a treatment head for a far-infrared treatment apparatus.

[0039] See also Figure 1 To Figure 6, in one embodiment, the treatment head includes a heating shell, a heating element, an outer shell and a fan, the heating shell includes a heating base and a heat-conducting cover, a first mounting groove is formed inside the heating base, and a slot connected to 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 part of the slot, and a first heat-insulating gap is formed between the edge of the heat-conducting cover and the slot wall of the first mounting groove; the heating element is arranged on the heating base and accommodated in the first mounting groove; a heat-insulating cavity is formed inside the outer shell, the heating shell is accommodated in the heat-insulating cavity, and a ventilation gap is formed between the inner side wall of the outer shell and the outer side wall of the heating shell; a ventilation opening connected to the ventilation gap is opened on the outer side wall of the outer shell; the fan is arranged in the heat-insulating cavity and is arranged corresponding to the ventilation opening, so as to guide outside air into the ventilation cavity.

[0040] The treatment head designed in the present invention includes a heating base, a heating element and a heat-conducting cover. The first mounting groove formed inside the heating base is used to accommodate the heating element, while the heat-conducting cover covers part of the groove and forms a first thermal insulation gap between the heat-conducting cover and the groove wall of the heating base. Since the heat-conducting cover covers part of the groove of the heating element and the existence of the first thermal insulation gap, there is no direct contact between the heating base and the heat-conducting cover. Heat is mainly transferred to the heat-conducting cover by thermal radiation rather than directly by heat conduction, so that the thermal radiation can be more concentratedly directed to the treatment area, reducing the transfer of heat to the non-heating area (mainly the area not used for directly emitting heat for treatment, such as the side wall of the heating base) of the outer shell surface, thereby improving the utilization efficiency of thermal energy. In addition, air or other materials with low thermal conductivity efficiency (such as asbestos or organic thermal insulation materials) can be used as thermal insulation media between the first thermal insulation gap, thereby further reducing the shell temperature of the non-heating area on the front side of the treatment head. In addition, in order to prevent the shell temperature of the non-heating area on the rear side from being too high, the present application designs a relatively sealed ventilation gap between the outer shell and the heating shell, which effectively isolates the heating shell and the outer shell, reducing the heat directly transferred to the outer shell. In addition, a fan is arranged on the outer shell to guide the cold air from the outside into the ventilation gap, thereby taking away the heat around the heating shell, and the operation of the fan can make the air in the ventilation gap flow, thereby effectively absorbing the heat transferred from the heating shell, avoiding the accumulation of heat in the local area, and thus making the heat of the heating shell no longer dissipate to the non-heating area of ​​the outer shell, and the utilization efficiency of thermal energy is improved, and more heat is directed to the area that needs treatment. In summary, the treatment head provided by the present invention optimizes the heat transfer path of the front and rear sides of the treatment head by setting the first insulation gap and the ventilation gap, which not only reduces the unnecessary loss of heat, but also significantly improves the heating efficiency and heat distribution uniformity of the far-infrared therapeutic device, ensuring the safety of the equipment and the comfort experience of the user.

[0041] It should be noted that in order to form the first thermal insulation gap, it is necessary to ensure that when the thermally conductive cover is installed on the heating base, its edge will not be aligned with the edge of the mounting groove, thereby forming a circle of gap between the contact edges of the thermally conductive cover and the heating base. When installing the thermally conductive cover and the heating base, a second locking seat and a second locking member can be provided. Specifically, the second locking seat is provided on the thermally conductive cover, and the second locking seat is provided with a locking groove; one end of the second locking member passes through the heating base and is locked in the locking groove, thereby ensuring the fixation between the thermally conductive cover and the heating base, preventing relative movement, and maintaining the stability of the heat conduction path. At the same time, the connection structure is also convenient for future disassembly and maintenance, and only the second locking member needs to be loosened or locked. The second locking member can be a bolt, a screw, a pin or other similar fastener, and the specific shape and size depend on the design of the equipment and the required fixing strength. Furthermore, to ensure the stability of the connection, multiple second locking members and multiple second locking seats can be used for combined fixing. Multiple second locking seats can be arranged at intervals along the circumference of the heat-conducting cover, and the first connection structure is arranged at equal distances or at specific design intervals along the circumference (i.e., circumferential direction) of the heat-conducting cover, so as to ensure that the heat-conducting cover is evenly stressed on the heating base, thereby improving the stability of the overall structure and the efficiency of heat conduction. This multi-point fixing design enhances the structural strength of the entire infrared treatment head, and can maintain the firmness of the connection even in long-term use or under the influence of external vibration.

[0042] In one embodiment, the outer shell includes a base and an element plate, the base and the element plate are connected to enclose a heat-insulating cavity, the heat-generating shell is contained in the heat-insulating cavity; the base is provided with the vent. The design of the heat-insulating cavity provides an insulation layer between the heat-generating shell and the outer shell, which helps to reduce the direct transfer of heat to the outer shell, thereby reducing the surface temperature of the outer shell. The setting of the element plate ensures that the user will not directly contact the heat-generating shell during use, thereby improving the safety of the device. Through the vent and the fan on the base, the external cold air is sucked into the heat-insulating cavity and contacts the heat-generating shell, taking away the heat, thereby reducing the temperature of the heat-generating shell and cooling the outer shell at the same time.

[0043] It should be noted that the element plate is a medical device that uses specific electromagnetic waves for treatment. This treatment plate is coated with a scientific formula based on the various elements required by the human body. Under the action of temperature, it can generate oscillating signals with characteristic information of various elements. After these signals enter the human body with infrared rays, they resonate with the corresponding elements in the body, thereby activating the activity of various enzymes in the body, enhancing the absorption of deficient elements, adjusting the relative balance of elements in the body, inhibiting the increase of free radicals in the body, repairing microcirculation channels, etc., so as to improve the body's own immune function and disease resistance.

[0044] In one embodiment, the base includes a base body and a guide ring disposed on the base body, the base is provided with a first through hole connected to the heat insulation cavity, the guide ring is accommodated in the heat insulation cavity and is disposed around the periphery of the first through hole; the bottom wall of the base body is provided with the vent; the element plate includes a cover body and a plug-in ring, the cover body is provided with a second through hole, the plug-in ring is disposed on a side of the cover body close to the first through hole and is disposed around the periphery of the second through hole, and the plug-in ring is plugged into the guide ring. The design of the guide ring and the plug-in ring ensures the precise docking between the element plate and the base, improves the accuracy and convenience of assembly, and the structure in which the plug-in ring is plugged into the guide ring provides a stable fixation for the element plate, prevents the element plate from accidentally moving or falling off during use, and improves the safety of the equipment. This design allows the element plate to be easily disassembled and reinstalled, which is convenient for maintenance and cleaning of the equipment. In other embodiments, the element plate and the base can also be connected together through a variety of structures, such as: screw fixation, screw holes are designed at corresponding positions of the base and the element plate, and the two are tightly fixed together by screws and nuts; snap connection, snaps and slots are designed on the edges of the base and the element plate, and the element plate is snap-connected to the base by pressing or sliding; magnet adsorption, magnets are installed on the contact surface of the base and the element plate, and the two are adsorbed together by magnetic force, which is convenient for quick disassembly and installation.

[0045] In one embodiment, the outer wall of the guide ring is provided with a first through hole; the outer wall of the plug-in ring is provided with a second through hole; the base further includes a first connection structure, the first connection structure includes a first locking seat and a first locking member, the first locking seat is provided on the base body and one end of the first locking seat is passed through the first through hole to be located on the inner side of the guide ring, and the first locking seat is provided with a first locking groove on the side 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. During installation, the plug-in ring is inserted into the guide ring to ensure that the two are aligned, one end of the first locking member is passed through the first through hole of the guide ring and the second through hole of the plug-in ring, and the first locking member is locked in the first locking groove, thereby fixing the element plate and the base. Through the first connection structure, the connection between the element plate and the base is more secure and not easy to loosen. When the element plate needs to be disassembled for maintenance or cleaning, it is only necessary to loosen the first locking member, which is easy to operate. The first locking member may be a bolt, a screw, a pin or other similar fasteners, and the specific shape and size depend on the design of the device and the required fixing strength.

[0046] In one embodiment, the outer wall of the seat body is provided with a third through hole connected to the heat insulation cavity, and the base further comprises an outlet pipe, which is plugged into the third through hole to be connected to the seat body. Through the design of the heat insulation cavity and the outlet pipe, the internal high temperature area can be effectively isolated from the external environment, protecting the wires and lines from heat damage. The use of the outlet pipe avoids direct exposure of the wires to the outside, reducing safety hazards caused by wire wear or contact with high temperatures, and the design of the outlet pipe facilitates the replacement and maintenance of the wires, and the operation can be performed without completely disassembling the equipment.

[0047] In one embodiment, a heat-conducting protrusion is formed on a side of the heat-conducting cover close to the heating element corresponding to the heating element, and a heat-conducting groove is formed on a side of the heat-conducting protrusion away from the heat-conducting cover, and the heat-conducting groove and the bottom wall of the first mounting groove are enclosed to form a heat-conducting cavity; the heating element is accommodated in the heat-conducting cavity. The heat-conducting protrusion is usually designed to enhance heat conduction. It can be a protruding part on the heat-conducting cover, which is convenient for close contact with the heating element (such as an electric heating pipe) to increase the contact area, thereby more directly transferring heat from the heating base to the heat-conducting cover, and improving the heat conduction efficiency. The shape and size of the heat-conducting protrusion usually match the shape of the heating element to ensure the maximum thermal contact area. The design of the heat-conducting groove helps to guide the heat from the heating element to the heat-conducting cover and dissipate it through the heat-conducting cover. The heat-conducting groove can also serve as a channel for air circulation to help dissipate heat.

[0048] In one embodiment, the treatment head further includes a second connection structure, the second connection structure includes a clamping column and a clamping seat, the clamping seat is provided with a clamping groove, one of the clamping column and the clamping seat is arranged on the heat-conducting cover and is arranged adjacent to the heat-conducting protrusion, the other of the clamping column and the clamping seat is arranged on the heat-generating base, and the clamping column is inserted into the clamping groove to connect the heat-conducting cover and the heat-generating base. Providing the second connection structure near the heat-conducting protrusion can ensure the continuity and efficiency of the heat conduction path and reduce thermal resistance. The clamping column is inserted into the clamping groove. This insertion method can be achieved by buckle, thread or other mechanical connection methods. This connection method ensures the precise alignment and firm connection between the heat-conducting cover and the heat-generating base, while allowing for rapid disassembly and reassembly under certain circumstances.

[0049] In one embodiment, the heating shell further includes a heat insulation cover, a second mounting groove is formed on one side of the heat insulation cover, the heating base is accommodated in the second mounting groove, and a second heat insulation gap is formed between the outer side surface of the heating base and the groove wall of the second mounting groove. The first heat insulation gap reduces direct heat conduction between the heating base and the heat conductive cover, while the second heat insulation gap prevents heat from being transferred from the heating base to the heat insulation cover. This design makes the heat more concentrated on being emitted in the form of thermal radiation through the heat conductive cover, thereby improving the utilization efficiency of thermal energy. The first heat insulation gap and the second heat insulation gap together constitute a double-layer treatment head, which further reduces the temperature of the device housing, reduces the risk of users accidentally contacting high-temperature surfaces during use, and helps to achieve a more uniform heat distribution, thereby improving the effect of far-infrared treatment.

[0050] Similarly, when installing the heating base and the heat shield, a locking seat and a locking member can be provided. Specifically, the locking seat is provided on the heating base, and a locking groove is provided on the locking seat; one end of the locking member passes through the heat shield and is locked in the locking groove, thereby ensuring the fixation between the heating base and the heat shield, preventing relative movement, and maintaining the stability of the heat conduction path. At the same time, the connection structure is also convenient for future disassembly and maintenance, and only needs to loosen or lock the locking member. The locking member can be a bolt, screw, pin or other similar fastener, and the specific shape and size depend on the design of the equipment and the required fixing strength.

[0051] See also Figure 7 The present invention also provides a far-infrared therapeutic apparatus, including a support frame and a therapeutic head. The specific structure of the therapeutic head refers to the above embodiment. Since the far-infrared therapeutic apparatus adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the outer shell of the therapeutic head is arranged on the support frame.

[0052] In one embodiment, the outer shell is rotatably arranged relative to the support frame. The rotatable arrangement of the outer shell greatly improves the flexibility of the therapeutic device, and the user can adjust the treatment head to the most suitable angle according to his or her needs, thereby improving the comfort and effect of the treatment, and further making the therapeutic device more widely applicable to various parts of the body, such as the back, legs, arms, etc., thereby increasing the scope of application of the therapeutic device.

[0053] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
