Description

Technical Field

[0001] This utility model belongs to the field of moxibustion therapy smoke treatment technology, specifically a smoke recovery pipeline assembly. Background Technology

[0002] Existing moxibustion devices produce smoke during moxibustion due to the burning of moxa sticks or moxa wool. This smoke can be bothersome for users and pollute the surrounding environment. Most existing smoke recovery devices use an end-collecting hood located on the outside of the moxibustion device, employing negative pressure to draw the smoke into a collection box for treatment before discharging. For example, CN210934258U uses an in-box smoke purification device. However, this approach has certain shortcomings:

[0003] 1. Direct negative pressure recovery through the smoking hood can easily cause the airflow at the moxibustion site to carry away some heat, resulting in a cold sensation at the moxibustion site. This not only makes the moxibustion effect unsatisfactory but may even aggravate the symptoms.

[0004] 2. Because the smoke contains moxa oil and particulate matter, if the smoke is processed inside the box, it will result in moxa oil, particulate matter, and moisture remaining on the inner wall of the pipe. Utility Model Content

[0005] The technical problem to be solved by this utility model is:

[0006] 1. Direct negative pressure recovery through the smoking hood can easily cause some heat to be carried away from the moxibustion site, resulting in a cold sensation at the moxibustion site. This not only makes the moxibustion effect unsatisfactory but also aggravates the symptoms.

[0007] 2. Because the smoke contains moxa oil and particulate matter, if the smoke is processed inside the box, moxa oil, particulate matter, and moisture will remain on the inner wall of the pipe, making the pipe prone to mold growth.

[0008] To solve the above-mentioned technical problems, the inventors of this utility model, through practice and summarization, have derived the technical solution of this utility model, which adopts the following technical solution:

[0009] A smoke recovery duct assembly includes a joint duct component, one end of which is a smoke inlet and the other end is a smoke outlet. A filter structure is installed at the smoke inlet. The end of the filter structure away from the joint duct component is a closed structure, and the periphery of the filter structure is a smoke filtration section.

[0010] In a preferred embodiment, a smoke baffle is installed on the side of the filter structure away from the smoke inlet end. The smoke baffle extends freely from the center outward to the outer periphery of the filter structure, and a groove is provided circumferentially on the side of the smoke baffle facing the filter structure.

[0011] In a preferred embodiment, the distance between the outer peripheral surface of the smoke shield and the outer peripheral surface of the filter structure in the horizontal projection plane is 5-35mm.

[0012] In a preferred embodiment, the bottom surface of the smoke shield gradually shifts towards the filter structure on the side furthest from the center.

[0013] In a preferred embodiment, the smoke shield is a barrel-shaped structure, and the smoke shield is fitted onto the side of the filter structure away from the joint pipe fitting.

[0014] In a preferred embodiment, the joint pipe fitting includes a pipe body and a joint, and both the pipe body and the joint are provided with multiple adjacent pipe bodies connected by the joint.

[0015] In a preferred embodiment, the tube body includes a middle tube and T-shaped end tubes connected to both ends. Each end of the joint is provided with an earmuff extending away from the middle. The interior of both the earmuff and the joint is a hollow structure. Damping structures are installed at corresponding positions of the earmuff and the T-shaped end tube.

[0016] In a preferred embodiment, the damping structure includes a serrated annular structure disposed on the T-shaped end tube and the joint, and an adjustment structure is installed on the joint for adjusting the damping structure.

[0017] In a preferred embodiment, the adjustment structure includes an adjustment knob, a lead screw, and a nut. The nut is fixed inside the earcup, the lead screw is rotatably mounted on the earcup corresponding to the position of the nut, and one end of the lead screw is threadedly connected to the nut. The adjustment knob is mounted on the lead screw and located on the outside of the earcup.

[0018] In a preferred embodiment, a valve is rotatably installed inside the T-shaped end tube near the filter structure. A connecting frame is installed on the valve, and the connecting frame is rotatably installed on the joint. An opening and closing knob is installed on the connecting frame, and the opening and closing knob is fitted onto the outside of the lead screw.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This utility model uses a detachable filter structure at the smoke inlet of the pipe to filter and remove moxa oil and particles from the smoke inlet. This can avoid the problem of pollution inside the pipe and the closed structure at the end of the filter structure can prevent the airflow from being directly drawn out, which would cause the moxibustion site to feel cold.

[0021] 2. In this utility model, after the filter structure has been used for a period of time, the moxa oil on the surface is prone to dripping under the action of gravity. The smoke baffle extends outward and a groove is set on it. The groove can prevent the moxa oil from dripping directly. Secondly, the outer part of the bottom surface can guide the smoke to the smoke filter part.

[0022] 3. This novel jointed pipe fitting features a hollow structure, allowing for multi-angle and multi-dimensional adjustment via the pipe body and joint. A damping structure and adjustable damping mechanism are incorporated at the joint, facilitating angle adjustment. Furthermore, a valve is installed within the T-shaped end pipe near the smoke filter structure, enabling opening and closing. The internal rotating opening and closing mechanism provides a better seal compared to traditional rotary valves, reducing smoke leakage. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Example 1

[0036] like Figure 1 , 2 As shown in Figure 3, a smoke recovery duct assembly includes a joint duct component 100. One end of the joint duct component 100 is a smoke inlet end 110 and the other end is a smoke outlet end 120. A filter structure 130 is installed on the smoke inlet end 110 (in a detachable manner, such as by threaded connection or snap-fit). The end of the filter structure 130 away from the joint duct component 100 is a closed structure, and the periphery of the filter structure 130 is a smoke filtering part.

[0037] In practical implementation, a smoke collection hood is installed at the end of the joint pipe component 100 near the smoke inlet 110. The smoke collection hood covers the top of the moxibustion device. The generated moxa smoke enters the smoke inlet 110 through the filter structure and is discharged from the smoke outlet 120. The discharge can be powered by natural upward airflow or by negative pressure suction. Because the filter structure 130 has a closed end, it cannot directly and quickly discharge the smoke, which causes the airflow to be reversed. This solves the problem of the moxibustion site becoming cold.

[0038] Example 2

[0039] The following improvements were made based on Example 1, such as... Figure 2 , 3 As shown, a smoke-blocking cover 131 is installed on the side of the filter structure 130 away from the smoke inlet 110. The smoke-blocking cover 131 extends freely outward from the center to the outer periphery of the filter structure 130, and a groove 132 is circumferentially provided on the side of the smoke-blocking cover 131 facing the filter structure 130. After the filter structure 130 has been used for a period of time, the filtered moxa oil will accumulate and is prone to dripping under the action of gravity. The groove 132 can catch the moxa oil and prevent it from dripping and contaminating the moxibustion site.

[0040] By limiting the outward extension of the smoke baffle 131, the problems of oil collection, flow guidance and smoke retention can be taken into account. The distance between the outer peripheral surface of the smoke baffle 131 and the outer peripheral surface of the filter structure 130 in the horizontal projection plane is 5-35mm.

[0041] Utilizing the structural constraints of the bottom surface to ensure smoke diversion, such as Figure 4 As shown, the bottom surface of the smoke shield 131 moves away from the filter structure 130 along the side away from the center and then towards the filter structure 130.

[0042] Example 3

[0043] The following improvements were made based on Example 1, such as... Figure 5 , 6 As shown, the smoke shield 131 is barrel-shaped and is fitted onto the side of the filter structure 130 away from the joint pipe fitting 100. The barrel-shaped structure helps to catch the moxa oil and prevent it from dripping. The height of the smoke shield 131 is 5-10mm, and the effective smoke filtration height of the smoke filtering part is approximately 1 to 10 times the height of the smoke shield.

[0044] Example 4

[0045] The following improvements were made based on Example 1, such as... Figure 1 , Figure 5 , Figures 7 to 9 As shown, the articulated pipe fitting 100 includes a pipe body 140 and an articulated fitting 150. Both the pipe body 140 and the articulated fitting 150 are provided with multiple adjacent pipe bodies 140 connected by the articulated fitting 150. The angle of the pipe body 140 is adjusted by the articulated fitting 150, thereby determining the position and angle of the end filter structure 130.

[0046] The tube body 140 includes a middle tube 141 and T-shaped end tubes 142 connected to both ends (except for the middle tube 141 connected to the filter structure 130, only one end of the middle tube 141 is connected to the T-shaped end tube 142). The joint member 150 has earmuffs 151 extending away from the center at both ends. Both the earmuffs 151 and the joint member 150 have hollow interiors. Damping structures 152 are installed at corresponding positions on the earmuffs 151 and the T-shaped end tubes 142. The damping structures 152 allow for angle adjustment of adjacent middle tubes 141 without affecting the connection between the joint member 150 and the tube body 140.

[0047] The damping structure 152 includes serrated annular structures disposed on the T-shaped end tube 142 and the joint 150. Two serrated annular structures are used to adjust the angle and provide constraint after adjustment. An adjustment structure is installed on the joint 150 for adjusting the damping structure 152. The adjustment structure includes an adjustment knob 155, a lead screw 153, and a nut 154. The nut 154 is fixed inside the earcup 151. The lead screw 153 is rotatably mounted on the earcup 151 corresponding to the position of the nut 154, with one end of the lead screw 153 threadedly connected to the nut 154. The adjustment knob 155 is mounted on the lead screw 153 and located on the outside of the earcup 151. Rotating the adjustment knob 155 rotates the lead screw 153, bringing the nut 154 closer to the adjustment knob 155, thereby causing the two earcups 151 to move closer together, thus damping the overall structure.

[0048] Example 5

[0049] The following improvements were made based on Example 4, such as... Figures 7 to 11 As shown, a valve 156 is rotatably installed inside the T-shaped end pipe 142 near the filter structure 130. A connecting bracket 157 is mounted on the valve 156, and the connecting bracket 157 is rotatably mounted on the joint 150. An opening / closing knob 158 is mounted on the connecting bracket 157, and the opening / closing knob 158 is fitted onto the outside of the lead screw 153. The valve 156 is rotated by rotating the opening / closing knob 158, thus achieving an active opening and closing function. Compared with the previous flap valve, this provides a better sealing effect and prevents smoke leakage.

[0050] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
