[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.
[0027] Please also read Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a hot air infrared therapy device 100 according to one embodiment of the present invention. Figure 2 for Figure 1 The structure diagram of the hot air infrared therapy device 100 shown in another perspective is as follows. Figure 3 for Figure 1 A cross-sectional schematic diagram of a hot air infrared therapy device 100 is shown.
[0028] The hot air infrared therapy device 100 provided by the present invention is used for emitting hot air, which can soothe the peripheral nerves and capillaries of the human body by utilizing the suitable temperature and blowing characteristics of the hot air, and at the same time help the sweat glands of the human epidermis to excrete, and has better therapeutic effect.
[0029] The hot air infrared therapy device 100 includes a shell 10, a heating element (not shown), a fan (not shown), a power source 20 and a guide tube 30. The heating element, the fan and the power source 20 are all accommodated inside the shell 10. One end of the guide tube 30 extends into the shell 10, and the other end extends out of the shell 10.
[0030] The shell 10 is used to protect the heating element, fan and power source 20, and isolate the relatively fragile heating element, fan and power source 20 in the hot air infrared therapy device 100 from the external environment, so as to prevent the external environment from interfering with the normal operation of the heating element, fan and power source 20; the heating element is used for heat supply, and the fan is used to fan the air on the surface of the heating element and form forced convection; the power source 20 is used to drive the fan to rotate; the guide tube 30 is used to guide the discharge of hot air, so that the hot air infrared therapy device 100 has targeting and can achieve directional emission to specific parts of the user.
[0031] The heating element is heated by the supply of external energy, and supplies the heat energy generated by itself to the air convection generated by the fan through the fan, thereby forming hot air; the hot air is then blown to the specific part of the user under the guidance of the guide tube 30, soothing the peripheral nerves and capillaries in the specific part of the user, helping the user's epidermal sweat glands to excrete, thereby realizing the physical therapy and health care function for the user.
[0032] Specifically, the shell 10 is roughly in the shape of a long tube, which includes a first shell 11 and a second shell 12. The interiors of the first shell 11 and the second shell 12 are hollow and can be assembled with each other. The assembled first shell 11 and the second shell 12 form an internal hollow accommodating chamber 101, and the heating element, fan and power source 20 are all accommodated in the accommodating chamber 101.
[0033] In this embodiment, the first shell 11 and the second shell 12 are two symmetrical assembled structures. The first shell 11 and the second shell 12 are assembled in half to form the shell 10. The first shell 11 and the second shell 12 are assembled in half to facilitate the installation of the heating element, the fan and the power source 20. The threaded connection method has better connection reliability and convenient assembly and disassembly.
[0034] It is understandable that in other embodiments, the first shell 11 and the second shell 12 may be assembled in other ways besides being assembled in half, and the first shell 11 and the second shell 12 may be fixed in other ways such as snap-fitting, gluing, etc.
[0035] In the present invention, the approximately middle portion of the shell 10 is tilted outward to form a grip portion 13, which is composed of a portion of the first shell 11 and a portion of the second shell 12. The grip portion 13 is for the user to hold, thereby facilitating the user's use.
[0036] The tilted setting of the grip portion 13 can facilitate the user's grip, and the housing 10 and the guide tube 30 form an overall gun-like shape, thereby improving the appearance and convenience of use. The middle part of the grip portion 13 is narrower than the end part, which further facilitates the user's grip.
[0037] In the present invention, a switch button 14 and a mode button 15 are provided on the outer surface of the shell 10. The switch button 14 is used by the user to control the start and stop of the hot air infrared therapy device 100, and the mode button 15 is used by the user to control the operating mode of the hot air infrared therapy device 100, such as changing the wind speed or temperature of the hot air output by the hot air infrared therapy device 100.
[0038] Furthermore, the switch button 14 and the mode button 15 use a key body with the same structure to increase the structural interchangeability of the hot air infrared therapy device 100 and improve the reliability and stability of the entire device.
[0039] In the present invention, a ventilation hole 16 is opened at one end of the shell 10 relatively far away from the guide tube 30. The ventilation hole 16 is the air inlet of the hot air infrared therapy device 100. The fan rotates and inhales cold air from the external environment through the ventilation hole 16, and then blows it onto the heating element to form hot air.
[0040] Furthermore, there are a plurality of ventilation holes 16, which are provided in the form of a grid hole group at one end of the housing 10 relatively far from the guide tube 30. A large number of ventilation holes 16 is helpful to improve the blowing efficiency of the fan.
[0041] The heating element is electrically connected to an external power source through a wire medium 21, and can generate heat under the energy supply of the external power source and heat the cold air rolled by the fan. The external power source can be an AC mains used in households, or a DC power such as a battery.
[0042] Furthermore, the heating element may be a heating wire or a ceramic heater, as long as the heating element can generate heat energy and heat the cold air rolled by the fan.
[0043] The fan is arranged corresponding to the heating element and can rotate under the drive of the power source 20, so as to inhale cold air from the external environment through the ventilation holes 16 and blow the cold air over the heating element, so that the self-rolling airflow is heated by the heating element and becomes hot air.
[0044] In this embodiment, the fan is a turbo fan, thereby reducing the fan's requirement on the overall space size of the housing 10, which helps to reduce the overall size of the hot air infrared therapy device 100. It is understood that in other embodiments, the fan may also be an axial flow fan.
[0045] The power source 20 is connected to the fan and can drive the fan to rotate. In this embodiment, the power source 20 is a brushless motor, and the fan is mounted on the motor shaft of the brushless motor and rotates with the rotation of the motor shaft, thereby rolling the air inside the housing 10. Since the brushless motor has very low signal interference to electronic components, stable operation, relatively low noise, and relatively low maintenance cost, the use of a brushless motor as the power source 20 can further improve the stability and reliability of the hot air infrared therapy device 100.
[0046] It is understandable that in other embodiments, the power source 20 may also adopt other types of motors such as a brushed motor, as long as the power source 20 can drive the fan to rotate.
[0047] In this embodiment, an infrared emitting element (not shown) is further provided in the hot air infrared therapy device 100. By integrating the infrared therapy function into the hot air infrared therapy device 100, the therapy effect of the hot air infrared therapy device 100 is improved.
[0048] Furthermore, the infrared emitting element uses a emitting lamp to generate infrared rays, and the infrared emitting element is electrically connected to an external power source or a battery provided inside the hot air infrared therapy device 100 through a wire medium or the like. The infrared emitting element radiates infrared rays under the energy supply of electric energy, and radiates them onto the human body through the guide tube 30, thereby achieving physical therapy for specific parts of the user.
[0049] It can be understood that the present invention does not limit the infrared emitting element to using an emitting lamp to generate infrared rays; in other embodiments, the infrared emitting element can also be integrated on a heating element, in which case the outer surface of the heating element is coated with a rare earth coating, which releases visible light when the heating element is energized, and the rare earth coating changes the frequency range of the visible light under the action of heat and forms infrared rays.
[0050] The guide tube 30 is roughly a cylindrical tube with a hollow interior, one end of which extends into the shell 10 and is connected to the accommodating cavity 101 inside the shell 10, and the other end extends out of the shell 10; the guide tube 30 can guide the radiation direction of infrared rays and hot air, and its own guiding function makes the hot air infrared therapy device 100 as a whole have a targeted function, which can radiate designated parts of the human body at a fixed point, and has a significant improvement in user experience.
[0051] In this embodiment, the guide tube 30 is a hollow straight tube. It is understood that in other embodiments, the guide tube 30 can also be a hollow curved tube or other shapes of pipes.
[0052] Please also read Figure 4 , Figure 4 for Figure 3 The hot air infrared therapy device 100 is shown as an enlarged schematic diagram at A. In order to overcome the noise problem generated by the traditional hot air infrared therapy device during therapy, the hot air infrared therapy device 100 provided by the present invention is provided with a sound absorbing hole 41 on the inner wall of the guide tube 30. When the noise generated by the fan, the power source 20 and other devices due to their own operation is transmitted outward through the inner wall of the guide tube 30, the air particles will vibrate and rub against the hole wall formed by the sound absorbing hole 41, thereby converting part of the sound energy into heat energy, so that the noise generated by the hot air infrared therapy device 100 gradually decays as the propagation distance along the guide tube 30 increases, thereby reducing the noise of the hot air infrared therapy device 100 and improving the user experience.
[0053] Furthermore, there are multiple sound absorbing holes 41, which are arranged one by one along the axial direction of the guide tube 30, and the distance between two adjacent sound absorbing holes 41 is equal. Such arrangement can improve the efficiency of sound energy conversion, so that noise can be more efficiently converted into heat energy.
[0054] It is understandable that in other embodiments, the multiple sound absorbing holes 41 may also be arranged in other ways such as a ring-shaped arrangement, as long as the multiple sound absorbing holes 41 can achieve the conversion of sound energy.
[0055] In one embodiment of the present invention, a porous sound-absorbing element 42 is also provided on the inner wall of the guide tube 30, and the porous sound-absorbing element 42 is made of porous material; when the noise generated by the hot air infrared therapy device 100 enters the porous material, the dense holes inside the porous material will cause the air particles to vibrate and rub against the hole walls, so that part of the sound energy is further converted into heat energy, thereby further reducing the noise of the hot air infrared therapy device 100 and improving the user experience.
[0056] Furthermore, the porous sound absorbing element 42 can be made of organic fiber sound absorbing material, inorganic fiber sound absorbing material, inorganic foam sound absorbing material or foam plastic sound absorbing material. The present invention does not limit the specific material of the porous sound absorbing element 42, as long as the porous sound absorbing element 42 can achieve noise reduction.
[0057] In one embodiment of the present invention, the guide tube 30 adopts a two-section structure, which includes an air outlet portion 31 and a guide portion 32, the air outlet portion 31 and the guide portion 32 are coaxial and interconnected; the sound absorption hole 41 and the porous sound absorption element 42 are both arranged on the inner wall of the guide portion 32.
[0058] The air outlet portion 31 serves as an air outlet, which is connected to the outside and the guide portion 32; the guide portion 32 serves as a guiding part, which is used to guide the hot air, so that the hot air can be smoothly ejected out of the hot air infrared therapy device 100 through the air outlet portion 31.
[0059] In this embodiment, the inner diameter of the air outlet portion 31 is smaller than the inner diameter of the guide portion 32. Such a configuration can increase the wind speed at the air outlet and improve the user experience.
[0060] Furthermore, a guide slope 33 is provided between the air outlet portion 31 and the guide portion 32, and the guide slope 33 connects the air outlet portion 31 and the guide portion 32 and enables a smooth transition between the two. The setting of the guide slope 33 reduces the energy loss of the hot air at the air outlet and can avoid the introduction of noise.
[0061] In one embodiment of the present invention, a spoiler 43 is further provided on the inner wall of the guide portion 32. The spoiler 43 is protruded from the inner wall of the guide portion 32 and is used to disturb the hot air so that the hot air is sprayed onto the human body in a rolling turbulent manner, further improving the user experience.
[0062] It can be understood that the spoiler 43 can be formed integrally with the guide portion 32, or can be a separate structure and arranged on the inner wall of the guide portion 32 by welding, gluing, etc.
[0063] First, the spoiler is used for spoiling, and then the guiding slope 33 is used for downstream flow, so that the user can first contact with the relatively smooth hot air, and the center of the hot air convection forms turbulence, which has a better experience effect. Of course, without considering the user experience and the physiotherapy effect, the guiding slope 33 and the spoiler 43 can also be removed at the same time, and the step surface formed between the guide part 32 and the air outlet part 31 can be used for spoiling. In this way, the manufacturing cost of the hot air infrared physiotherapy device 100 is relatively low, which has certain cost advantages.
[0064] In one embodiment of the present invention, an energy stone ring (not shown) is also provided on the inner wall of the guide portion 32. The energy stone ring is made of tourmaline and rare earth materials. The energy stone ring can generate negative oxygen ions, thereby regulating the air quality and further ensuring the therapeutic effect and user experience.
[0065] Specifically, tourmaline has spontaneous permanent electrical polarity, which creates a permanent electrostatic field around the tourmaline particles, which can cause slight and continuous ionization of moisture in the surrounding air to produce negative oxygen ions. The concentration of negative oxygen ions released by tourmaline is related to the strength of its spontaneous polarization effect. Tourmaline with a stronger polarization effect can increase the concentration of negative oxygen ions produced by the energy stone ring. Rare earth materials mixed with tourmaline can enhance the polarization effect of tourmaline and have a better therapeutic effect.
[0066] The hot air infrared therapy device 100 provided by the present invention has sound absorption holes 41 on the inner wall of the air guide duct 30, and the noise reduction ability of the sound absorption holes 41 is utilized to reduce the noise of the hot air infrared therapy device 100, thereby improving user experience and product competitiveness, and has broad application prospects.
[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0068] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
