Description

Technical Field

[0001] This invention belongs to the field of air purification and separation technology, specifically relating to a device for absorbing and purifying moxibustion smoke. Background Technology

[0002] While moxibustion treats diseases, the burning of moxa wool also produces smoke (moxa smoke). The smoke contains a large amount of particulate matter, which deteriorates the indoor environment. Prolonged exposure to moxa smoke can irritate the respiratory tract and cause symptoms such as coughing and throat discomfort. The smoke problem is the most important factor hindering the development and promotion of moxibustion. Therefore, it is necessary to absorb and purify the moxa smoke to separate harmful substances.

[0003] In existing technologies, vertical filter cloths are used, allowing water to flow downwards from above the filter cloth to form a water curtain. When flue gas passes through, the water absorbs and removes particulate matter. To improve the filtration effect, multiple layers of the water curtain are often used. However, due to the resistance encountered when flue gas passes through the water curtain, using multiple layers reduces the efficiency of flue gas passage, resulting in a lack of significant improvement in the absorption effect of flue gas particles. Summary of the Invention

[0004] This invention provides a moxibustion smoke absorption and purification device, which solves the technical problem in related technologies where setting multiple layers of water curtain reduces the efficiency of smoke passage, resulting in a lack of significant improvement in smoke particle absorption.

[0005] This invention provides a moxibustion smoke absorption and purification device, including a housing, a water tank at the upper end of the housing, a filter chamber below the water tank, a filter mechanism inside the filter chamber, and multiple sets of filter separation components arranged from top to bottom. Each filter separation component includes a conical cover fixedly installed with the housing, and multiple slots are formed in the circumferential direction of the conical cover. A filter cloth is fixedly installed inside the slots. A fan blade is provided above each set of filter separation components. The moxibustion smoke absorption and purification device also includes an air intake component, a power component, and a water intake component. The air intake component is used to draw moxibustion smoke into the filter chamber, the water intake component is used to pump water onto the filter cloth, and the power component is used to drive the fan blades to rotate so that the fan blades transport the moxibustion smoke downward.

[0007] Preferably, the power assembly includes an outer tube, which is rotatably mounted in the middle of the inner side of the housing. A motor is provided at the bottom of the housing to drive the outer tube to rotate. The upper end of the conical cover is attached to the outer wall of the outer tube, and the fan blades are fixed on the outer tube.

[0009] Preferably, the upper end of the filter chamber is provided with an air inlet that communicates with the filter chamber and is connected to the output end of the air pump; one side of the lower part of the filter chamber is provided with an air outlet; and the bottom of the filter chamber is provided with a water outlet.

[0010] Preferably, the moxibustion smoke absorption and purification device also includes a water pump, the input end of which is connected to the water outlet at the bottom of the filter chamber, the output end of which is connected to the water tank, and the upper end of the water pipe extends into the bottom of the inner side of the water tank.

[0011] Preferably, a cleaning component is provided directly below each filter separation component. The cleaning component includes an annular tube with elastic plates corresponding to the slots on the annular tube. The elastic plates are located directly below the filter cloth. Multiple support rods are installed on the lower side of the annular tube and are fixedly installed on the housing. One of the support rods is connected to the output end of the second water pump as a pipe. The second water pump pumps water into the annular tube through the support rod.

[0012] Preferably, each elastic sheet is provided with multiple water outlet components. Each water outlet component includes a housing, which is fixed to the elastic sheet. The two ends of the housing have an outlet and an inlet, respectively. The outlet faces one side of the filter cloth, and the inlet is located inside the annular tube.

[0013] Preferably, the inner part of the outer casing is provided with a ball bearing and a spring, and the two ends of the spring are pressed together with the outer casing and the spring, thereby pressing the ball bearing at the inlet position.

Thus, even with multiple layers of filtration and separation components, the moxibustion smoke still has high permeability, improving the absorption effect of particulate matter.

The moxibustion smoke collides with the water at high speed, and the moxibustion smoke can be encapsulated and settled by the water, thereby filtering out the moxa oil in the moxibustion smoke.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] like Figures 1-8 As shown, a moxibustion smoke absorption and purification device includes a housing 1, a water tank 11 at the upper end of the housing 1, a filter chamber 12 below the water tank 11, a filter mechanism inside the filter chamber 12, and the filter mechanism includes multiple sets of filter separation components 3 arranged from top to bottom.

[0021] In the above technical solutions, such as Figures 3-7 As shown, the filter separation assembly 3 includes a conical cover 31 fixedly installed with the housing 1. The conical cover 31 has multiple holes and slots 32 in the circumferential direction. Filter cloth 33 is fixedly installed inside the holes and slots 32. Each filter separation assembly 3 is provided with a fan blade 4 above it.

[0022] It should be noted that the material of filter cloth 33 can be polypropylene (PP) meltblown cloth, polytetrafluoroethylene (PTFE) filter cloth, etc.

[0023] In the above technical solutions, such as Figure 1 As shown, the moxibustion smoke absorption and purification device also includes an air intake component 2, which is used to draw moxibustion smoke into the filter chamber 12. Specifically, the air intake component 2 includes an air pump 21, a smoke hood 22 and an air pipe 23. The input end of the air pump 21 is connected to the smoke hood 22 through the air pipe 23, and the output end of the air pump 21 is connected to the interior of the filter chamber 12.

[0024] It should be noted that the upper end of the filter chamber 12 is provided with an air inlet 13 that communicates with the filter chamber 12. The air inlet 13 is connected to the output end of the air pump 21. The conical cover 31 is installed on the air inlet 13, and the smoking hood 22 is also installed on the air inlet 13 through a bracket. An air outlet 14 is provided on one side of the lower part of the filter chamber 12. The moxibustion smoke is pumped into the interior of the filter chamber 12 by the air intake component 2, and after being filtered by the filter separation component 3, it is discharged from the air outlet 14.

[0025] In the above technical solutions, such as Figure 3 As shown, the moxibustion smoke absorption and purification device also includes a power component 5, which is used to drive the fan blades 4 to rotate so that the fan blades 4 can transport the moxibustion smoke downward. Specifically, the power component 5 includes an outer tube 51, which is rotatably installed in the middle of the inner side of the housing 1. A motor 52 is provided at the bottom of the housing 1, which is used to drive the outer tube 51 to rotate. The upper end of the conical cover 31 is attached to the outer wall of the outer tube 51, and the fan blades 4 are fixed on the outer tube 51.

[0026] It should be noted that the lower and upper ends of the outer tube 51 are rotatably connected to the lower and upper ends of the housing 1, respectively. The lower end of the outer tube 51 has a larger diameter, which can accommodate the motor 52. The motor 52 is located at the bottom of the outer tube 51 and is mounted on the housing 1. The output end of the motor 52 is fixedly connected to the outer tube 51 through a connector, so that the motor 52 can drive the outer tube 51 to rotate. When the outer tube 51 rotates, it can drive the fan blade 4 to rotate together.

[0027] In the above technical solutions, such as Figure 3 and Figure 5 As shown, the moxibustion smoke absorption and purification device also includes a water inlet assembly 6, which is used to pump water onto the filter cloth 33. Specifically, the water inlet assembly 6 includes an inner tube 61, the upper end of which is fixed to the top of the housing 1. The outer side wall of the inner tube 61 is attached to the inner side wall of the outer tube 51. The side wall of the outer tube 51 has a side opening 511 corresponding to the fan blade 4. A water pipe 62 is fixedly installed on the inner side of the inner tube 61. The upper end of the water pipe 62 is located inside the water tank 11. Several spray pipes 63 are fixedly connected to the water pipe 62. The ends of the spray pipes 63 penetrate the side wall of the inner tube 61 and can be attached to the outer side wall of the outer tube 51. The ends of the spray pipes 63 face the blade 41 of the fan blade 4 from the side opening 511.

[0028] It should be noted that, since the upper end of the outer tube 51 is rotatably connected to the upper end of the housing 1, and the upper end of the inner tube 61 is fixed to the top of the housing 1, the water tank 11 is designed as a ring structure. An outlet is provided at the bottom of the filter chamber 12, and a water pump is installed on the outside of the housing 1. The input end of the water pump is connected to the outlet at the bottom of the filter chamber 12, and the output end of the water pump is connected to the water tank 11. The upper end of the water pipe 62 extends into the bottom of the inner side of the water tank 11. With the water pipe 62 inside the water tank 11, the water pump draws the water from the bottom of the filter chamber 12 back into the water tank 11. Under pressure, the water enters through the water pipe 62 and is sprayed out from the nozzle 63.

[0029] It should also be noted that the purpose of the side opening 511 is to enable the nozzle 63 to spray water onto the fan blade 4 from the side opening 511. During the rotation of the outer tube 51, the nozzle 63 is always able to spray water onto the fan blade 4 through the side opening 511.

[0030] In this embodiment, the specific implementation method is as follows: The device is placed at the location where moxibustion smoke needs to be processed. The air intake assembly 2, water pump 1, and motor 52 are activated. The air pump 21 draws in the smoke generated by burning moxa wool from the smoke hood 22, which then enters the interior of the filter chamber 12 through the air pipe 23 and the air inlet 13. The water pump 1 pumps water from the water tank 11 into the water pipe 62. Water is sprayed from the front end of the nozzle 63 through the side opening 511, wetting the filter cloth 33 and allowing it to flow downwards. The water can also pass through the filter cloth 33 and flow down to the lower layer of the filter separation assembly 3. The motor 52 drives the outer pipe 51 to rotate, which in turn drives the fan blades 4 to rotate. The fan blades 4 push the moxibustion smoke downwards, filtering it as it passes through the filter cloth 33, and finally discharging it from the air outlet 14. Specifically, during the absorption and purification of moxibustion smoke, the air intake assembly 2 draws the moxibustion smoke into the filter chamber 12 through the air inlet 13. At this time, the moxibustion smoke is located at the top of the filter chamber 12 and flows downward through the filter cloth 33 under the pumping pressure of the air pump 21. As the moxibustion smoke passes through the filter cloth 33, the particulate matter in the moxibustion smoke is filtered out by the filter cloth 33. Because water flows downward on the filter cloth 33, the particulate matter will flow downward along the upper surface of the filter cloth 33, so that the particulate matter will not always accumulate on the filter cloth 33, thus improving the particulate matter processing capacity of the filter cloth 33. However, since the filter separation assembly 3 is provided with multiple sets, the resistance is relatively large when the smoke flows downward. Therefore, in this embodiment, the motor 52 drives the outer tube 51 and the fan blades 4 to rotate. The blades 41 of the fan blades 4 are tilted, so that the blades 41 can push the moxibustion smoke downward, that is, increase the pushing force on the moxibustion smoke. And each layer has fan blades 4 to push, thereby improving the flowability of the moxibustion smoke and improving the separation and purification efficiency. In the above process, the water sprayed from the nozzle 63 hits the blades 41. Since the blades 41 are rotating, they can disperse the water, causing the water to splash everywhere. The moxibustion smoke collides with the water at high speed, and the moxibustion smoke in the moxibustion smoke can be wrapped by the water and settle.

[0031] The above technical solution utilizes an inclined, water-soaked filter cloth 33 to filter particulate matter from the moxibustion smoke as it passes through. By employing multiple layers of filtration and separation components 3, with fan blades 4 positioned above each layer, the fan blades 4 provide downward thrust to the moxibustion smoke. Therefore, even with multiple layers of filtration and separation components 3, the moxibustion smoke maintains high permeability, improving the absorption of particulate matter. Furthermore, by spraying water from the nozzle 63 onto the fan blades 41, the blades 41 disperse the water, causing it to splash everywhere. The high-speed collision between the moxibustion smoke and water encapsulates and settles the moxibustion smoke, thus filtering out the moxa oil within the smoke.

[0032] When installing filter cloth 33, it should not be taut. Therefore, during use, the middle part of filter cloth 33 may sink slightly. In this case, particles will accumulate in the middle of filter cloth 33, affecting its filtration effect. Therefore, the following technical solution is proposed.

[0033] like Figures 9-10 As shown, a cleaning component 7 is provided directly below each filter separation component 3. The cleaning component 7 includes an annular tube 71. An elastic sheet 72 corresponding to the slot 32 is provided on the annular tube 71. The elastic sheet 72 is located directly below the filter cloth 33. Multiple support rods 73 are installed on the lower side of the annular tube 71. The support rods 73 are fixedly installed on the housing 1. One of the support rods 73 is connected to the output end of the second water pump as a pipe. The second water pump pumps water into the annular tube 71 through the support rod 73.

[0034] It should be noted that the elastic sheet 72 is made of rubber. Water is supplied from the support rod 73 to the inside of the annular pipe 71 by the water pump 2. After the water enters, under the action of pressure, the elastic sheet 72 expands towards the filter cloth 33. After the elastic sheet 72 contacts the filter cloth 33, it lifts the filter cloth 33 upward, thereby eliminating the grooves generated when the filter cloth 33 is in use. During the lifting process, the water flowing downward along the upper surface of the filter cloth 33 can flush the particles separated on the filter cloth 33 upward, thereby improving the filtration and separation capacity of the filter cloth 33.

[0035] Furthermore, such as Figure 10 As shown, each elastic sheet 72 is provided with multiple water outlet components 74. The water outlet component 74 includes a housing 741, which is fixed to the elastic sheet 72. The two ends of the housing 741 have an outlet 742 and an inlet 743, respectively. The outlet 742 faces the side of the filter cloth 33, and the inlet 743 is located inside the annular tube 71.

[0036] Furthermore, the interior of the housing 741 is provided with a ball 744 and a spring 745. The two ends of the spring 745 are pressed against the housing 741 and the spring 745, thereby pressing the ball 744 at the position of the inlet 743. The diameter of the ball 744 is smaller than the inner diameter of the housing 741.

[0037] It should be noted that in the initial state, the spring 745 is compressed, the ball bearing 744 blocks the inlet 743, and after the water pump 2 pumps water into the annular tube 71, the elastic plate 72 expands upward to lift the filter cloth 33. The pressure continues to increase, overcoming the pressure of the spring 745 and lifting the ball bearing 744. Thus, the water inside the annular tube 71 can be sprayed upward from the outlet 742 through the inlet 743. On the one hand, this can increase the fluidity of the water on the surface of the filter cloth 33. On the other hand, the outlet 742 presses against the filter cloth 33, and when the water is sprayed out, it can vibrate the filter cloth 33, further causing the particles on the filter cloth 33 to flow downward quickly.

[0038] like Figure 7 As shown, a number of side grooves 311 are provided at the outer edge of the conical cover 31. A support frame 8 is fixedly installed inside the side grooves 311, and a filter cloth 81 is installed inside the support frame 8.

[0039] It should be noted that the water flowing downward along the upper surface of filter cloth 33 gathers at the lower side of the upper surface of the conical cover 31 and can flow downward through filter cloth 81. Filter cloth 81 can be made of a material with good permeability, such as gauze, so that the water can flow downward quickly.

[0040] Working principle: Place this device at the location where moxibustion smoke needs to be treated, and process it according to the following procedure.

[0041] Air pump 21 draws in the smoke from burning moxa wool through the smoke hood 22, which then enters the uppermost part of the filter chamber 12 via the air pipe 23 and air inlet 13. Water pump 1 pumps water from the water tank 11 into the water pipe 62, and water is sprayed from the front end of the nozzle 63 through the side opening 511, hitting the blades 41 and wetting the filter cloth 33, which then flows downwards. Motor 52 drives the outer pipe 51 and fan blades 4 to rotate, and the fan blades 4 push the moxibustion smoke downwards. During this process, the moxibustion smoke flows downwards and is filtered as it passes through the filter cloth 33. Particulate matter in the moxibustion smoke is filtered out by the filter cloth 33. Because water flows downwards on the filter cloth 33, the particulate matter flows downwards along the upper surface of the filter cloth 33. The blade 41 disperses the water, causing it to splash everywhere. The moxibustion smoke collides with the water at high speed, and the moxibustion smoke inside the smoke is encapsulated and settled by the water. The filtered moxibustion smoke is finally discharged from the outlet 14. After a period of use, water is supplied from the support rod 73 to the inside of the annular pipe 71 by the second water pump. Under pressure, the elastic plate 72 expands towards the filter cloth 33. After the elastic plate 72 contacts the filter cloth 33, it pushes the filter cloth 33 upward. The pressure continues to increase, overcoming the pressure of the spring 745 and pushing the ball 744 upward. Thus, the water inside the annular pipe 71 can be sprayed upward from the outlet 742 through the inlet 743. This increases the fluidity of the water on the surface of the filter cloth 33 and also vibrates the filter cloth 33, causing the particles on the filter cloth 33 to flow downward quickly.

[0042] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
