Description

  The present invention relates to a stagnation heater, and more particularly, to a stagnation heater that heats a heat conducting member using a coiled tube and indirectly transmits heat energy to a diseased part of a user by a contact member.

  In recent years, with the rapid development of the economy, the lives of modern people have gradually become wealthy, and people are not satisfied with just being satisfied with clothing and food as they were in the past, and they are beginning to emphasize quality of life and medical health. However, because the rhythm and tempo of modern people are getting faster and faster, the stress of work is also increasing, and if you can't relax your body and feeling properly, it becomes a very serious problem physiologically and psychologically, and your body pain Or upsets easily. Therefore, many people have a physical and mental relaxation effect through Satsuma or massage. However, Satsuma completely stimulates the acupoints of the human body and adjusts the functions of the body by the force of manual massage, but the effect of Satsuma by the general public is not significant.

  In the Chinese medical culture, “Acupuncture, Acupuncture, Drugs, Suction Balls, Massage” is collectively called the five major therapies. “Acupuncture” refers to mogaku acupuncture, which is based on the principle that heat conduction is used to introduce the amount of heat generated after burning the cord into the acupuncture point via the body surface, and the pain is stimulated through thermal stimulation. It is also called “warm acupuncture” because it can alleviate and induce disease resistance. In addition to effectively relieving fatigue of the human body, warm acupuncture has a remarkable effect of regulating blood pressure, breathing, pulse, heart rate, nerves, and blood vessels. Since acupuncture does not stimulate the acupuncture points in the body using acupuncture as a medium unlike acupuncture, it has a relatively high level of acceptance by the general public and is gradually becoming popular in recent years.

  Since acupuncture therapy stimulates and induces the meridians and acupoints of the human body mainly through thermal energy, thermal energy is not always generated by the “medicinal herb combustion” method. Many of the commercially available hot water heaters generate heat energy by an electric heating method so that the affected area of the user is swallowed, and the therapeutic effects of hot water, massage and massage can be realized through heat. Referring to FIG. 1, a conventional hot water heater 1 includes a grip portion 11, lamp heat source means 12, and a heat storage portion 13. The grip portion 11 is a hollow tube body in which a lamp socket 110 is provided. The lamp heat source means 12 is mounted on the lamp socket 110. The heat storage section 13 covers the grip 11 and corresponds to one end of the lamp heat source means 12. After the lamp heat source means 12 is energized, the light is stored on the heat storage section 13. By projecting to the heat storage unit 13 and projecting the heat energy to the heat storage unit 13, the user can swallow the affected part with the warm water heater 1 and perform a massage.

However, regardless of the warm water heater 1 or various commercially available warm water heaters, there are many inconveniences in actual use, and the user's willingness to use is reduced as follows. .
(1) Low heat transfer effect: Referring to FIG. 1, the hot water heater 1 generates heat energy by the lamp heat source means 12, and after the lamp heat source means 12 is energized, it generates light and heat energy, ie, lamp Most of the electric energy received by the heat source means 12 is converted into light, and the remaining part is converted into heat energy, so that the conversion efficiency of the hot water heater 1 is too low. In addition to this, since the lamp heat source means 12 and the heat storage section 13 do not contact each other, the heat energy generated by the lamp heat source means 12 is transmitted to the heat storage section 13 by radiation (passing light) or convection (passing air). In addition, heat energy is lost during the transmission process. From this, it can be seen that there is still much room for improvement in the heat generation principle of the hot water heater 1 both in terms of conversion efficiency and transmission effect.
(2) Power consumption is large: In addition to the hot water heater 1 shown in FIG. 1, there is a hot water heater that generates heat by using a heating wire or an electric heating plate. However, the power consumption of the heating wire or the heating plate is extremely large, and the power consumption is excessive, which reduces the willingness of general users to purchase and makes it difficult to spread and sell.
(3) Non-uniform temperature: Since acupuncture therapy requires pressing the affected area for a certain period of time, “uniform thermal energy” and “high temperature” are one of the major factors that affect the effectiveness of thermal therapy. . Taking the warmer 1 shown in FIG. 1 as an example, the heat storage unit 13 is made of a metal material, so that the heat energy generated by the lamp heat source means 12 can be quickly transmitted to the affected part. However, if the electric power control in the hot water heater 1 is unstable and the generated thermal energy is excessive, the user can easily be burned easily, and conversely, an injury will occur. There are some manufacturers who have produced a case of a warmer using an insulating material. However, since the heat conduction of the insulating material is relatively slow, problems such as uneven heat energy or inability to maintain temperature for a long time are likely to occur.

  Therefore, how to design a stagnation warming device that not only combines thermal energy conduction and conversion efficiency but also allows the user to perform thermal therapy by outputting thermal energy stably will be solved by the present invention. It became an important issue.

  In light of the problem that the conversion and transfer efficiency of thermal energy existing in various current hot water heaters is too low, and the stable and uniform temperature cannot be maintained, the inventor has intensively researched, tested and improved over the years through research and development experience. As a result, we finally devised the stagnation heater of the present invention and expect to solve the above-mentioned many problems effectively.

  The purpose of the present invention is to have the advantages of low power and high conversion rate, to ensure the uniformity of thermal energy distribution and accuracy of temperature range, and to effectively improve the convenience and therapeutic effect of acupuncture therapy. The aim is to provide a possible sipable warmer.

In order to achieve the above object, a stagnation heater of the present invention includes a pedestal, a contact member, a control circuit, a coil tube, and a heat conduction member. The pedestal has a receiving groove recessed at one end, and a first assembly portion is provided at a position close to the receiving groove.
The contact member is made of an insulating material (e.g., a wooden warm wharf), and is provided with a second assembly part at one end, and the second assembly part can be connected to the first assembly part ( Example: Locking or screwing), a closed space is formed by sealing the receiving groove.
The control circuit is provided in the accommodation groove, and is electrically connected to a power supply unit (eg, a power outlet, a battery), and can generate a drive signal by power supplied from the power supply unit.
The coil tube is fixed in a closed space, has a hollow insulating seat and a heating coil, and the heating coil is wound around the insulating seat and is electrically connected to the control circuit. When the drive signal is direct current, heat energy can be generated by passing a direct current, and when the drive signal is alternating current, an alternating magnetic field is generated in a closed space by passing an alternating current. To do.
The heat conducting member is made of a metal material and has an induction part and a conduction part. The induction portion has a structure corresponding to the insulating seat, and can be inserted at a position corresponding to the heating coil in the insulating seat. The conduction part has one end connected to the induction part and the other end abutted to the inner wall surface of the contact member, and the heat energy generated by the heating coil is contact member in the order of the insulating seat, the induction part, and the conduction part. The heat energy generated by the induction current generated by the induction portion by the electromagnetic induction by the alternating magnetic field generated by the heating coil can be transmitted to the contact member.

In the present invention, the drive signal generated from the control circuit can be an alternating current. Moreover, an induction current generate | occur | produces in the induction | guidance | derivation part of a heat conductive member by a heating coil generating an alternating magnetic field in closed space by passage of alternating current. The heat conduction member generates heat by the induced current and can transmit heat energy to the contact member.
The method of generating heat energy by the coiled tube and transferring the heat energy indirectly to the affected part of the user by the heat conducting member is low power (about 2 to 5 W) and has a merit of high conversion rate. It is possible to guarantee the uniformity of the thermal energy distribution and the accuracy of the temperature range (40-50 ° C.), and to effectively improve the convenience and therapeutic effect of the acupuncture therapy.

(First embodiment)
FIG. 2 shows a stagnation heater according to the first embodiment of the present invention. The stagnation heater 2 according to this embodiment includes a pedestal 21, a contact member 22, a control circuit 23, a coil tube 24, and a heat conducting member 25. A receiving groove 210 is recessed at one end of the pedestal 21, and a first assembly portion 211 is provided at a position close to the receiving groove 210. The contact member 22 is made of an insulating material (in this embodiment, it is woody, but in fact any non-metallic insulating material can be used), and the structure is a hollow housing. A second assembly portion 221 is provided around one end of the contact member 22, and a contact arc surface 222 is provided at the other end.
In the present embodiment, the first assembly portion 211 is a concave groove, the second assembly portion 221 protrudes and can be fixed in the first assembly portion 211 by a packing method, and the inside of the contact member 22 is hollow. A closed space is formed between the housing groove 210 and the housing groove 210. However, in another preferred embodiment of the present invention, the structure of the assembly parts 211 and 221 is not limited to this, and the assembly parts 211 and 221 can also be coupled to each other by a method such as screwing or locking. This point will be described in advance.

  The control circuit 23 is provided in the accommodation groove 210 and receives power supplied from the power supply means 20 by being electrically connected to the power supply means 20 (e.g., power outlet, battery), and also has a drive signal. Can be generated. The coil tube 24 is fixed in a closed space and includes an insulating seat 241 and a heating coil 242. In the present embodiment, the insulating seat 241 has a hollow shape and is provided with a stopper 243 at one end. The heating coil 242 can receive a drive signal by being wound around the intermediate portion of the insulating seat 241 and electrically connected to the control circuit 23.

  The heat conducting member 25 is made of a metal material, and includes a guiding portion 251 and a conducting portion 252, and the structure of the guiding portion 251 matches the insulating seat 241, so that the position corresponding to the heating coil 242 in the insulating seat 241. Can be inserted into. One end of the conductive portion 252 is connected to the guide portion 251, and its cross-sectional width matches the length of the stop portion 243, so that it can abut on the stop portion 243. A conductive arc surface 253 is provided at the other end of the conductive portion 252, the structure of the conductive arc surface 253 matches the structure of the contact arc surface 222, and the other end of the conductive portion 252 is in close contact with the inner wall surface of the contact member 22. Thus, the heat energy generated by the heating coil 242 can be sequentially transmitted to the outside of the contact member 22 through the insulating seat 241, the induction portion 251, and the conduction portion 252.

  Next, it will be respectively described that the stagnation heater 2 of the present invention can be operated normally regardless of the use of direct current or alternating current. When the drive signal is direct current, the heating coil 242 has a constant and non-negligible resistance (the resistance calculation formula of the conductive wire is Formula 1), and the power is obtained by Formula 2. According to the actual test of the inventor, when the driving signal is supplied with a fixed voltage of 12 volts and the heating coil 242 has 1500 turns (in the preferred embodiment of the present invention, the number of turns of the heating coil 242 is 500 to 2500 turns). 1), the current on the heating coil 242 is about 0.2 milliamps, that is, the power is about 4-5 watts, and the prior art lamp heat source means 12 shown in FIG. (The power of a general incandescent bulb is about 70-100 watts). In this case, the temperature on the heating coil 242 is about 50 ° C., the temperature on the outside of the contact member 22 is about 45 ° C., the overall thermal energy loss is extremely low, and the thermal energy distribution is uniform.

  Further, when the drive signal is alternating current, the operating state of the heating coil 242 can be inferred from Equation 3 and Equation 4 of electromagnetic induction. An alternating magnetic field can be generated in 220. The lines of magnetic force generated by the alternating magnetic field can generate a significant change in magnetic flux density in the heat conducting member 25, and the heat conducting member 25 can generate thermal energy by generating an induced current therein by electromagnetic induction.

In summary, when the drive signal is a direct current, the heating coil 242 can generate thermal energy by passing a direct current. Alternatively, when the drive signal is alternating current, the heating coil 242 can generate an alternating magnetic field in the closed space 220 due to the passage of the alternating current. Therefore, the heating coil 242 is thermally conductive or electromagnetically induced through the heat conduction member 25. The induction portion 251 can be heated and heat energy can be sequentially transmitted to the outside of the contact member 22 through the insulating seat 241, the induction portion 251, and the conduction portion 252. With this, the massaging warmer 2 can achieve the following effects.
(1) Uniform heat transfer: The heat energy generated in the coil tube 24 is indirectly transferred to the insulating contact member 22 by the metal heat conduction member 25, so the temperature on the outside of the contact member 22 A temperature range that is uniform and hardly loses and that is suitable for hot water (that is, 40 to 50 ° C.) can be maintained for a long time. In addition to this, referring to FIG. 2, the thermal energy on the contact member 22 is concentrated on the portion in contact with the heat conducting member 25 (that is, the tip of the contact member 22), but the thermal energy generated by the coil tube 24 is also Since the air in the enclosed space 220 can be guided to other parts of the contact member 22, the side edge portion of the contact member 22 still has a certain degree of heat, and the stagnation heater 2 has a relatively large temperature range. Make it.
(2) High thermal conductivity: Since both the coil tube 24 and the heat conductive member 25 are sealed in the closed space 220, they are less likely to be lost during the heat energy transfer process. As described above, according to the test results of the inventor, when the temperature of the heating coil 242 is 50 ° C., the outside temperature of the contact member 22 is still maintained at about 45 ° C., and the thermal conductivity is excellent from now on. I understand.
(3) Low power: Compared with the stagnation heater 1 shown in FIG. 1, the present invention uses the coiled tube 24 to heat and does not need to project light and is relatively high in energy efficiency. It can work well just by using a power source (about 2-5 watts). In addition, referring to FIG. 2, since the power supply requirement of the present invention is low, the control circuit 23 can also be connected to a USB connection jack by a connection cable, and the user can connect the USB connection jack to an electronic device (for example, a personal computer, By plugging it into a USB port of a notebook computer (that is, it can supply a fixed voltage of 5 volts), you can do warmth anywhere and anytime.
(4) Compact structure: In addition, in the present invention, the structure of the coil tube 24 and the heat conducting member 25 is very simple and does not occupy an excessive volume space. This is advantageous for users.

(Second embodiment)
A stagnation heater according to the second embodiment of the present invention is shown in FIG. For convenience of explanation, components such as the insulating seat 241 and the heat conducting member 25 are omitted in FIG. The heating coil 242 can be further divided into a first coil part 242a and a second coil part 242b. One end of the first coil portion 242a is connected to the control circuit 23, and the connection side A is provided at the other end. One end of the second coil portion 242b is connected to the other end of the first coil portion 242a, and a connection side B is also provided at the other end. When the switching circuit 231 and the light emitting diode 232 are further provided on the control circuit 23, and the control circuit 23 is in operation, the light emitting diode 232 projects light to the user and the hot water heater 2 is currently in operation. You can be informed. The free end of the switching means 231 connects the connection sides A and B on the first coil part 242a or the second coil part 242b in a selectable manner. With this, the user can selectively adjust the connection state of the switching means 231 (for example, attaching a toggle switch on the pedestal) to change the degree of heat generation of the heating coil 242. When the first coil part 242a has 1000 turns and the second coil part 242b has 500 turns, when the switching means 231 is connected to the connection side B of the second coil part 242b, these coil parts 242a, Since current passes over 242b, regardless of resistance or generated alternating magnetic field, both are relatively large, and the contact member can be held at a suitable temperature (about 40-45 ° C.).

  On the contrary, when the switching means 231 is connected to the connection side A of the first coil part 242a, only the current of the first coil part 242a passes through the heating coil 242 at this time. The contact member can be kept at a relatively moderate temperature (about 38 to 40 ° C.). Referring to FIGS. 2 to 3, the user can adjust the magnitude of the thermal energy output from the stagnation heater 2 according to his / her needs, but the adjustment method of the stagnation heater 2 is not limited to this. The stagnation heater 2 can also achieve the purpose of changing the temperature outside the contact member 22 by changing the magnitude of the drive signal output from the power supply means 20.
