Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine fumigation, in particular to a smoke exhaust device for traditional Chinese medicine fumigation. Background Art

[0002] Chinese medicine fumigation is also known as Chinese medicine fumigation therapy, Chinese medicine steam bath therapy, medicine penetration therapy and hot mist therapy. It is a comprehensive chemical and physical therapy with hot medicine steam as the therapeutic factor. It is widely used in many aspects such as leisure health care, rehabilitation and clinical treatment of mental illness. Chinese medicine fumigation requires Chinese medicine to be placed in a high-pressure container for steaming, and then the steam containing Chinese medicine ingredients vaporized after steaming is sprayed through a pipe. However, the steaming of Chinese medicine will inevitably produce smoke, not only steam containing Chinese medicine ingredients, but also gases that have no effect on the efficacy of Chinese medicine, such as water vapor. Then the infiltration of such smoke will affect the effect of steam containing Chinese medicine ingredients, that is, it will affect the efficacy of Chinese medicine. Then the treatment of this smoke is what needs to be paid attention to in the work of Chinese medicine fumigation.

[0003] The Chinese patent authorization announcement number is CN211326751U, and the authorization announcement date is August 25, 2020. A traditional Chinese medicine fumigation instrument is disclosed, including a chassis in the shape of a hollow cavity and a controller arranged inside the chassis; a traditional Chinese medicine heating and evaporation device for heating the traditional Chinese medicine and generating steam is arranged inside the chassis through a sliding and pulling structure, and a drainage structure for discharging waste liquid is arranged at the bottom of the traditional Chinese medicine heating and evaporation device. The tops of the left and right sides of the traditional Chinese medicine heating and evaporation device are respectively connected by an exhaust connection structure to provide a jet cantilever with a hollow interior for conveying steam and a steam nozzle arranged at the end of the jet cantilever for spraying steam; a steam cooling mechanism for cooling the steam conveyed in the jet cantilever to meet the spraying requirements is coated on the outer wall of the jet cantilever; the controlled ends of the steam cooling mechanism, the traditional Chinese medicine heating and evaporation device and the drainage structure are respectively connected to the output end of the controller; the exhaust connection structure is connected to a liquid reflux mechanism for conveying the reflux liquid condensed under the action of the steam cooling mechanism. The shortcoming of this technical solution is that after the Chinese medicine steam is evaporated by the Chinese medicine heating evaporation device, it directly enters the exhaust pipe through the steam exhaust pipe, and then is sprayed under the guidance effect of the jet cantilever, but the gas during the fumigation of the Chinese medicine is not processed at all, so that too much water vapor or smoke generated during fumigation may enter the jet cantilever, which will have an adverse effect on the steam containing the Chinese medicine ingredients and affect the efficacy of the Chinese medicine.

[0004] In summary, a selective control can be set for the smoke generated during the fumigation of traditional Chinese medicine, so that the steam can be selectively utilized or discharged, which is convenient for the rational use of traditional Chinese medicine. Summary of the invention

[0005] The invention aims to overcome the deficiency of the prior art that the gas produced by the fumigation of traditional Chinese medicine is transported together, and provides a smoke exhaust device for the fumigation of traditional Chinese medicine which is equipped with a gas guide which can selectively perform gas guiding work.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A smoke exhaust device for Chinese medicine fumigation, comprising a chassis, on which a jet cantilever, a high-pressure container, a Chinese medicine heating and evaporating device, a switch assembly, a single-chip microcomputer and a connecting cylinder are installed, the high-pressure container is communicated with the Chinese medicine heating and evaporating device, the Chinese medicine heating and evaporating device is electrically connected to the single-chip microcomputer, the single-chip microcomputer is electrically connected to the switch assembly, an exhaust pipe and an air inlet pipe are installed on the high-pressure container, the exhaust pipe is communicated with one end of the jet cantilever, a connecting sleeve is installed at the other end of the jet cantilever, the connecting sleeve is communicated with the connecting sleeve, a jet pipe is installed on the connecting sleeve, a jet port is provided at the connection between the jet pipe and the connecting sleeve, a vent is provided at the connection between the connecting sleeve and the connecting sleeve, a moving block is installed in the connecting sleeve, a blockage and a control block are installed on the moving block, the position of the blockage corresponds to the position of the jet port on the left and right, the right end of the moving block matches the vent, and the right end of the control block is connected to the left end of the moving block, The control block is provided with a plurality of air ports which are evenly distributed. A control shaft is installed on the left end of the control block. One end of the control shaft is connected to the control block, and the other end of the control shaft passes through a connecting sleeve and is placed outside the air injection pipe.

[0007] This design allows the high-pressure container, the Chinese medicine heating evaporation device, the switch component, the single-chip microcomputer and the connecting tube to be installed on the chassis, so that the high-pressure container is connected to the Chinese medicine heating evaporation device. The Chinese medicine heating evaporation device here is electrically connected to the single-chip microcomputer, and the single-chip microcomputer is electrically connected to the switch component. In this way, the control electrical signal can be transmitted to the single-chip microcomputer through the control of the switch component. After the single-chip microcomputer processes the signal, it transmits the electrical signal to the Chinese medicine heating evaporation device. Then, the Chinese medicine heating evaporation device can evaporate the Chinese medicine in the high-pressure container. Moreover, an exhaust pipe and an air inlet pipe are installed on the high-pressure container, the exhaust pipe is connected with one end of the jet cantilever, and a connecting sleeve is installed on the other end, the connecting tube is connected with the connecting sleeve, and a jet pipe is installed on the connecting sleeve, a jet port is provided at the connection between the jet pipe and the connecting sleeve, and a vent is provided at the connection between the connecting sleeve and the connecting tube, a moving block is also installed in the connecting sleeve, a plug and a control block are installed on the moving block, the position of the plug corresponds to the position of the jet port on the left and right, and the right end of the moving block matches the vent, the right end of the control block is connected to the left end of the moving block, and a number of air ports are evenly distributed on the control block, not only that, the left end of the control block A control shaft is installed on the end, one end of the control shaft is connected to the control block, and the other end is placed outside the jet pipe through the connecting sleeve. In the process of evaporation of the high-pressure container, evaporated water vapor or gas generated by heating will be discharged through the exhaust pipe. In this way, you can first choose to control the end of the control shaft outside the jet pipe, and let the end of the control shaft in the connecting sleeve control the moving block to move left, so that the blockage on the moving block moves accordingly until it blocks the jet port corresponding to the left and right of the current position and the blockage. At the same time, the vent blocked by the moving block is also opened, so that the evaporated gas will be introduced into the connecting tube through the vent, and will not be discharged through the jet port. Then the gas in the connecting tube can return to the high-pressure container through the air inlet pipe to enter the heating and evaporation environment of traditional Chinese medicine. This cycle can allow the substances in the gas to evaporate repeatedly. Finally, the moving block can be controlled to move to the right to block the air vent. The blockage leaves the position where the jet is blocked, allowing the gas to pass through the air port on the control block and be discharged toward the jet. This is how the traditional Chinese medicine fumigation work is carried out. The movement of the moving block here to block and open the air vent achieves the purpose of installing a device that can selectively guide the gas.

[0008] Preferably, the jet port is placed at the upper end of the connecting sleeve, an air inlet is provided at the lower end of the connecting sleeve, the jet cantilever is connected to the connecting sleeve through the air inlet, and the moving block is in contact with the upper end of the connecting sleeve through a blockage.

This means that the moving block can be moved to the left so that the blockage on the moving block blocks the jet port at the upper end of the connecting sleeve, and the gas entering from the air inlet at the lower end of the connecting sleeve can only be introduced into the connecting tube through the vent, or the moving block can be moved to the right so that the moving block blocks the vent, and the blockage opens the jet port, and the gas entering from the air inlet automatically floats upward and is discharged through the jet port, that is, it is convenient to control the moving block to carry out the guided floating work of the gas.

[0009] Preferably, a moving plate is installed on the left end of the control block, the control shaft is connected to the control block through the moving plate, and the outer edge of the moving plate contacts the inner wall of the connecting sleeve.

The high-pressure container 6 here is equipped with an exhaust pipe 16 and an air inlet pipe 29, the exhaust pipe 16 is connected to one end of the jet cantilever 14, and the other end of the jet cantilever 14 is equipped with a connecting sleeve 12, and the connecting tube 32 is connected to the connecting sleeve 12, and the jet pipe 11 is installed on the connecting sleeve 12. The connection between the jet pipe 11 and the connecting sleeve 12 is provided with a jet port 34, and the jet port 34 is placed at the upper end of the connecting sleeve 12, and the lower end of the connecting sleeve 12 is provided with an air inlet 35, and the jet cantilever 14 is connected to the connecting sleeve 12 through the air inlet 35, and the connecting sleeve 12 is connected to the connecting tube 32. A vent 33 is provided at the connection, and a moving block 37 is installed in the connecting sleeve 12, and a plug 38 and a control block 36 are installed on the moving block 37. The position of the plug 38 corresponds to the position of the air jet 34 on the left and right. The right end of the moving block 37 matches the vent 33, and the right end of the control block 36 is connected to the left end of the moving block 37. The control block 36 not only has a plurality of air ports 39 evenly distributed, but also is installed with a moving plate 41. The outer edge of the moving plate 41 is in contact with the inner wall of the connecting sleeve 12, and the end of the control shaft 40 on the moving plate 41 passes through the connecting sleeve 12 and is placed outside the air jet pipe 11. In this way, the control structure at the connecting sleeve 12 can be known.

[0028] In addition, one end of the jet pipe 11 is connected to the connecting sleeve 12, and the other end is equipped with a cylindrical head 9, on which a fan 10 is installed, and a cavity 7 is provided in the cylindrical head 9, one end of the fan 10 is connected to the cavity 7, and the other end is provided with an air outlet 44, and the temperature sensor 28 installed in the cavity 7 is electrically connected to the single-chip microcomputer 5, and the single-chip microcomputer 5 is also electrically connected to the display 16 on the chassis 1, so that the outlet of smoke exhaust or Chinese medicine fumigation can be clearly understood, and the fan 10 here is not only provided with a cavity 27, but also equipped with a motor 4 electrically connected to the single-chip microcomputer 5 2. A first end ring 45 and a second end ring 46 are installed in the cavity 27. A motor shaft can be set on the motor 42. The first end ring 45 and the second end ring 46 can be connected to the motor shaft, and the two ends of the blade 43 can be connected to the first end ring 45 and the second end ring 46 respectively. The blade 43 includes a plurality of blades, and the spacing between adjacent blades 43 increases from the center of the fan 10 to the edge of the fan 10. A plurality of baffles 30 are also installed in the cavity 27. The first end ring 45 is connected to the fan 10 through the baffle 30. In this way, the structural characteristics of the fan 10 are known.

[0029] In this way, the Chinese medicine fumigation work can be carried out. After the control switch door 2 closes the chassis 1, the end of the control shaft 40 outside the connecting sleeve 12 can be manually controlled first, so that the movable plate 41 connected to the control shaft 40 drives the control block 36 and the movable block 37 to move left and right, until the movable plate 41 is blocked by the left arm of the connecting sleeve 12 and cannot continue to move. During the movement of the movable plate 41, the inner wall of the connecting sleeve 12 is the limit of the movable plate 41 to prevent the movable plate 41 from tilting and falling when moving, and the plug 38 on the movable block 37 moves along the movement of the movable block 37, which will smoothly block the jet port 34, and the vent 33 will be smoothly opened, and then through the control of the switch assembly 21 electrically connected by the plug, the motor 42, the Chinese medicine heating evaporation device 22 and the water pump 24 start working at the same time, and the motor shaft on the motor 42 can drive the first end ring 45 and the second end ring 46 to rotate, that is, drive the rotation of the blade 43, then the blade 43 has the effect of absorbing gas. The Chinese medicine heating and evaporation device 22 has the effect of heating and evaporating the Chinese medicine in the high-pressure container 6, and the water pump 24 draws the cooling liquid water in the water collecting tank 23 into the cooling water pipe 17, so that the cooling water is introduced into the cooling water bag 13, and the cooling water contacts the jet cantilever 14 wrapped by the cooling water bag 13 and flows downward until it flows into the recovery water tank 20 through the return pipe 18. The Chinese medicine heating and evaporation device 22 heats and evaporates the Chinese medicine in the high-pressure container 6, which will produce steam and smoke. Opening the valve 15 allows the steam and smoke to float upward under the guiding effect of the jet cantilever 14. The floating steam and smoke here are always floating under the cooling effect of the cooling water. Of course, in order to further cool, there can also be a device with a cooling effect in the connecting sleeve 12, such as a bag that can be used to introduce cooling water, so that the steam and smoke will also contact the cooling bag. Here, the steam will become liquid when it is cooled, and the liquid water cannot be smoothly discharged through the jet port 34 (the jet port 34 here can also be optionally installed with a screen, and the plug 38 can be smaller than the jet port 34 in width), and can only be introduced into the connecting tube 32 through the vent 33, and the air inlet pipe 29 in the connecting tube 32 allows the introduced gas or liquid water to flow back into the high-pressure container 6. Of course, the valve 2 31 on the air inlet pipe 29 must be opened to open the air inlet pipe 29. Of course, the smoke can be discharged through the air jet 34, and the smoke can be discharged again and again in a cycle.

[0030] Then the control shaft 40 can be controlled to move rightward again, until the blockage 38 on the moving block 37 is blocked by the right end of the connecting sleeve 12 and cannot move further, so that the moving block 37 is inserted into the vent 33, and the jet 34 is opened, and the injection of cooling water can be stopped in the cooling bag at this time, so that the steam can smoothly pass through the jet 34, under the guidance of the jet pipe 11, it floats into the cavity 7 of the column head 9, and then it can be discharged through the air outlet 44. Of course, for the fumigator, the temperature of the steam is also important, and the temperature sensor 28 installed in the cavity 7 can sense the temperature of the steam at all times, and transmit this temperature information to the single-chip microcomputer 5, and then display it on the display 16 after the single-chip microcomputer 5 processes it. When the displayed temperature is suitable for fumigation, then the air outlet 44 can be directed to the fumigator to smoothly carry out the fumigation work. Here, the moving block 37 is driven by the control shaft 40 to guide the floating of steam and smoke, and the purpose of installing the guide work of selectively carrying out gas is achieved.
