Description

Automatic temperature-regulating type radix aconiti lateralis preparata cake moxibustion device

Technical Field

The invention relates to an appliance for separating monkshood cake moxibustion.

Background

Monkshood moxibustion belongs to one of the separated moxibustion methods. The application of this method is first reported in Tang Dynasty Sun Simiao, Chin jin Fang. The radix Aconiti lateralis Preparata slice moxibustion and radix Aconiti lateralis Preparata cake moxibustion are divided. Cutting radix Aconiti lateralis, grinding, making into radix Aconiti lateralis cake with certain thickness, needling the middle part of the cake, and placing on acupuncture point to moxibustion with moxa cone; radix Aconiti lateralis may also be mixed with other adjuvants to make radix Aconiti lateralis cake, and moxibustion is performed by puncturing several holes with a needle and placing moxa cone thereon. In the prior practical application, the distance between the moxa cone and the monkshood cake is mainly adjusted through manual operation, so that the temperature of the monkshood cake acting on a human body is controlled, scalding is avoided, and the moxibustion effect is kept.

Some devices for completing moxibustion treatment operations exist in published literature documents, such as an automatic temperature-adjusting moxibustion instrument, a control method and a system of the automatic temperature-adjusting moxibustion instrument, which are disclosed in patent document with application publication number CN105919799A, the temperature is mainly adjusted and controlled through ventilation, the adjusting effect is limited, and automatic adjustment cannot be realized; the "drug-blocking moxibustion device" disclosed in the utility model patent publication No. CN206044975U can adjust the temperature of the drug-blocking moxibustion device acting on the human body by adjusting the relative position of the base 1 and the rear cover 2, but requires manual adjustment. The patent document with application publication number CN 108553288A discloses a medicine-separated moxibustion device, which controls the rotation of a motor by controlling a controller in the process of medicine-separated moxibustion, so as to automatically adjust the distance between a moxa column and the skin of an acupuncture point, and realize the automatic adjustment of the temperature of the medicine-separated moxibustion. But the mechanism is complex, and the distance adjustment can be realized only by a power supply, a worm gear mechanism driven by a motor and a temperature sensor.

The bimetallic strip is also called as a thermal bimetallic strip, and because the thermal expansion coefficients of all the sheet layers are different, when the temperature changes, the deformation of the active layer is larger than that of the passive layer, so that the whole bimetallic strip can bend towards one side of the passive layer, and the curvature of the composite material changes to generate deformation. Wherein, the active layer with higher expansion coefficient is called as the active layer; the lower expansion coefficient is called the passive layer. According to the difference of materials, the deformation temperature of the bimetallic strip is different, for example, the bimetallic strip with the temperature of 55-45 ℃ is deformed (in a bending state) when exceeding 55 ℃, and is deformed and restored (in a straight state) when reaching 45 ℃. GB/T4461-2007 thermal bimetallic strip specifies the brand, size, shape and permissible deviation of the thermal bimetallic strip, technical requirements, test methods, inspection rules, packaging, labeling and quality certificates. Although the design and application of the bimetallic strip in the field of electrical appliances, particularly low-voltage electrical appliances, have been well-developed and deeply researched, the bimetallic strip is applied as an actuating mechanism of an electrical appliance switch.

In the prior art, there are also bimetal strips used in moxibustion instruments, such as "frame type moxibustion instrument" disclosed in the utility model patent publication with the publication number CN2467068Y, in which the bimetal strip is provided at the position of the ventilation opening of the upper cover. The bimetallic strip covers and closes the vent when being bent and is opened when being reset, so that the temperature is automatically controlled; the utility model discloses a thermal power and electric dual-purpose portable moxibustion device, which is published in the utility model patent with the publication number of CN 202942397U, and adopts a normally closed bimetallic strip temperature controller to control the on-off of the circuit of a Ptc heating element. But the automatic control of the distance between moxa cone and monkshood cake can not be realized.

Detailed Description

Referring to the attached drawings, reflecting a specific structure of the invention, the automatic temperature-regulating type radix aconiti lateralis preparata cake moxibustion device comprises a copper base 2, wherein a sealing lantern ring 101 of a sucker 1 is sleeved outside the lower end part of the base 2. So as to position and fix the appliance on the skin of the human body.

The internal thread of the upper port of the base 2 is connected with the external thread on the side wall of the bottom of the upper cover 3 to form a sealed threaded connection. Meanwhile, the open lower port of the inner cavity of the base 2 is sealed by the monkshood cake 8 nested inside, so that the inner cavities of the base 2 and the upper cover 3 are integrally kept in a sealing state with certain strength, and the air exchange between the base and the outside is mainly completed by the outer vent hole 301 and the inner vent hole 501.

Nested a sliding sleeve 5 in the inner chamber of upper cover 3, the moxa cone 9 is installed to 5 interior devices of sliding sleeve, and the device pressure spring 7 that resets between the top of moxa cone 9 and the 3 inner chamber tops of upper cover, 7 one end of pressure spring that resets act on 3 tops of upper cover, and the other end acts on 9 tops of moxa cone, and its elasticity is ensured that sliding sleeve 5 possesses a decurrent pressure:

a heat insulation sheet 6 with a heat conduction middle hole 601 is arranged in the inner cavity of the base 2 above the monkshood cake 8; bimetallic strip 4 is installed to 6 tops of heat insulating sheet, bimetallic strip 4's passive layer up, 2 inner chamber lateral walls of root 401 rigid coupling bases of bimetallic strip 4, and bimetallic strip 4's free end is equipped with gyro wheel 402, and gyro wheel 402 rolls in order to realize lifting function in the bottom surface of end box 502 during deformation, and the gyro wheel makes the contact and the motion of bimetallic strip and end box more smooth, avoids the card that probably takes place to pause. In this example, the number of the bimetal 4 is two symmetrically distributed, and one or more bimetal 4 may be provided, and a plurality of the bimetal 4 are uniformly distributed on the circumferential surface below the bottom surface of the bottom case 502. The bimetallic strip can be produced by purchasing products with corresponding marks according to the trade names of the bimetallic strip and the hot bimetallic strip or by self-processing according to a known method. Mainly considering thermal sensitivity indexes such as temperature curvature, specific bending and the like.

The door element 602 that opens/closes the thermally conductive central hole 601 is hinged to the insulating sheet 6 made of glass fiber by means of a rotating shaft 603, and the rotating shaft 603 is provided with a return torsion spring (not shown in the figure) that keeps the door element 602 in an open position. The door element 602 is connected to the free end of the bimetal 4 (or a plurality of bimetal) by a cable 604, the cable 604 passes through a guide sleeve 605 to adjust the pulling direction of the cable 604, and the guide sleeve 605 can be replaced by a guide wheel or the like. When the bimetallic strip 4 deforms, the free end of the bimetallic strip pulls the door element 602 to rotate around the rotating shaft 603 by overcoming the resistance of the reset torsion spring through the pull rope 604, and the heat conduction central hole 601 is closed to isolate the lower end of the burning moxa cone 9 from directly roasting the monkshood cake 8; when the deformation of the bimetallic strip 4 is recovered, the pulling cable 604 is loosened, and the return torsion spring drives the door element 602 to return to open the heat conducting central hole 601, thereby recovering the direct roasting of the monkshood cake 8 by the burning lower end of the moxa cone 9.

The sliding sleeve 5 is provided with a bottom box 502 made of metal mesh, and the bottom surface of the bottom box 502 is supported on the passive layer of the bimetallic strip 4; the elasticity of the return compression spring 7 ensures that the sliding sleeve 5 has a downward pressure to ensure that the sliding sleeve and the sliding sleeve are in contact to fully realize heat exchange, so that the heat generated by the combustion of the moxa cone 9 at the lower end can be directly transmitted to the bimetallic strip 4 besides radiation. In other embodiments, the bottom surface of the bottom case 502 may be provided with a groove for receiving the bimetal 4. To further ensure a sufficiently immediate exchange of heat.

The side wall of the upper cover 3 is provided with an outer vent hole 301, and the side wall of the sliding sleeve 5 is correspondingly provided with an inner vent hole 501; when the bimetallic strip 4 deforms, the sliding sleeve 5 is pushed to move upwards, the outer vent hole 301 and the inner vent hole 501 are in a staggered state, so that oxygen supply is reduced, and the combustion degree of the moxa cone 9 is reduced; when the bimetallic strip 4 is deformed and restored, the reset pressure spring 7 pushes the sliding sleeve 5 to reset downwards through the moxa cone 9, and the outer vent hole 301 and the inner vent hole 501 are in a superposed state to keep ventilation and oxygen supply. The return compression spring 7 also keeps the burning lower end of the moxa cone 9 not detached from the base case 502 due to the combustion shortening, but always in close contact with the metal mesh.

The side wall of the metal mesh of the bottom box 502 is nested and matched with the inner cavity of the port on the base 2; as mentioned above, when the deformation occurs, the bottom case 502 rises, and the sidewall of the bottom case 502 contacts the sidewall of the inner cavity of the upper port of the base 2 for heat conduction and dissipation. In other embodiments, the bottom case 502 is provided with a heat dissipation structure, such as grooves, ribs, or holes on the outer surface for ventilation and heat dissipation, to improve the heat dissipation efficiency. When the deformation is recovered, the side wall of the bottom box 502 is separated from the side wall of the inner cavity of the upper port of the base 2, and the heat conduction is stopped.

The use method of the appliance comprises the following steps:

1. the burning moxa cone 9 is ignited and the lower end is inserted into the sliding sleeve 5, and the weight of the moxa cone 6 required for completing one moxibustion therapy is not more than 3 g;

2. the upper cover 3 is spirally connected with the upper port of the bottom box 2;

3. a monkshood cake 8 is arranged in the lower port of the base 2;

4. the base 2 is placed on corresponding acupuncture points of a human body for moxibustion, and the position of the heat conduction middle hole 601 is aligned to the acupuncture points of the human body to obtain the effect of fixed-point moxibustion;

5. in the moxibustion process, along with the accumulation of heat, when the bimetallic strip 4 reaches the deformation temperature of 55 ℃, the quadruple temperature adjusting mechanism is automatically started at the same time:

firstly, the free end of the bimetallic strip 4 lifts the sliding sleeve 5 to change the distance between the moxa cone 9 and the monkshood cake 9;

secondly, the free end of the bimetallic strip 4 drives the door element 602 to close the heat conducting middle hole 601 through the inhaul cable 604;

both of them can directly lower the temperature of the monkshood cake 8, thereby reliably lowering the sensible temperature.

Thirdly, the bottom box 502 formed by the metal mesh is contacted with the copper base 2, so that the heat on the metal mesh is rapidly conducted, dissipated and cooled;

fourthly, the sliding sleeve 5 is lifted, and the inner and outer ventilation holes 501 and 301 are closed in a staggered way, so as to directly reduce the burning degree of the moxa cone 9.

The temperature of the bimetallic strip 4 and the atmosphere thereof is automatically reduced under the composite action of the quadruple effect, and the quadruple temperature adjusting mechanism automatically resets along with deformation recovery when the temperature falls back to 45 ℃ which is the set temperature of the bimetallic strip 4. The operation is repeated and circulated. It is worth noting that when the deformation occurs, the moxibustion is still performed as often as possible without interruption, since no manual intervention is required. The patient can carry out the moxibustion by himself without any inconvenience. The heat effect is an important role in moxibustion, and the thermal stimulation of moxibustion not only involves the epidermis, but also affects the hypodermis and the muscular layer. Temperature is one of the important biophysical factors in the moxibustion treatment process. The heat generated by burning moxibustion is transmitted into human body via acupoints, and has effects of dredging channels and collaterals, invigorating qi and blood, tonifying deficiency, tonifying yang, warming channels, dispelling cold, and preventing and treating diseases. Thus, the sustained and proper warm stimulation is kept, and the moxibustion effect is improved.

The above-mentioned implementation is only for clearly illustrating the technical solutions of the present invention, and is not to be construed as limiting the present invention in any way. The present invention has many known alternatives and modifications in the art, which fall within the scope of the present invention without departing from the spirit of the present invention.
