Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for moxibustion equipment, specifically to a moxibustion smoke exhaust pipe, which is used to promptly exhaust the smoke generated during moxibustion treatment to improve the air quality of the moxibustion operating environment. Background Technology

[0002] During moxibustion treatment, the burning of moxa sticks produces a large amount of smoke. This smoke contains various components, which not only permeate the air and affect the comfort of the treatment environment, but may also pose certain health risks to the operators and patients. Therefore, it is necessary to use a smoke exhaust pipe to vent the smoke outdoors.

[0003] Currently, there are some moxibustion smoke exhaust pipes on the market, but these existing technologies have the following problems and drawbacks:

[0004] 1. Poor adjustment flexibility: Most existing moxibustion exhaust pipes have a fixed structure, making it difficult to adjust flexibly according to the specific location of the moxibustion equipment and the smoke generation. For example, some exhaust pipes can only be extended or retracted in one direction, and cannot achieve multi-dimensional and all-round position adjustment. When the location of the moxibustion equipment changes or the site layout changes, the existing exhaust pipes often cannot accurately align with the smoke emission point, resulting in poor smoke extraction effect.

[0005] 2. Complex operation: Although some existing smoke exhaust ducts have certain adjustment functions, the operation process is complicated and cumbersome. For example, the adjustment mechanism of some smoke exhaust ducts is not reasonably designed, requiring operators to use special tools to disassemble and assemble them multiple times to complete the adjustment. This not only increases the workload of operators but also reduces work efficiency. Moreover, the complicated operation process can easily lead to inaccurate adjustment and affect the smoke exhaust effect.

[0006] 3. Insufficient Stability: During smoke extraction, the exhaust duct needs to withstand a certain amount of suction and its own weight. Some existing exhaust ducts suffer from insufficient stability due to unreasonable structural design. For example, the expansion joints of some exhaust ducts are not securely connected, and they are prone to swaying or loosening during expansion and contraction. This not only affects the smoke extraction effect but may also pose safety hazards. Utility Model Content

[0007] To overcome the problems of poor adjustment flexibility, complex operation, and insufficient stability of existing moxibustion smoke exhaust pipes, this utility model provides a moxibustion smoke exhaust pipe with a horizontal drive component, a vertical drive component, and a circumferential drive component, which realizes multi-dimensional and flexible adjustment function, is easy to operate and has high stability, can effectively improve the moxibustion smoke exhaust effect, and improve the moxibustion operation environment.

[0008] The technical solution adopted by this utility model to solve its technical problem is as follows: a moxibustion smoke exhaust pipe, including a bend, which is divided into a first bend and a second bend. The side of the first bend is provided with a bracket for connecting to a wall. A horizontal flexible tube for lateral expansion and contraction is provided between the first bend and the second bend. A vertical flexible tube for longitudinal expansion and contraction is provided vertically downward at the other end of the second bend. A lateral drive component is provided below the horizontal flexible tube to control its lateral expansion and contraction. A longitudinal drive component is provided above the second bend to control the vertical flexible tube for longitudinal expansion and contraction. A circumferential drive component is provided below the lateral drive component to control the circumferential rotation of the smoke exhaust pipe.

[0009] The aforementioned moxibustion smoke exhaust pipe has a transverse drive component including a frame, a cantilever, a screw, a first motor, and a screw sleeve. The frame is connected to the first bend pipe and one side is connected to the wall via a hinged bracket. The cantilever is fitted inside the frame, the screw is located inside the frame, and the first motor is arranged at one end. The screw sleeve is located inside the cantilever and meshes with the screw.

[0010] The aforementioned moxibustion smoke exhaust duct, the horizontal drive component also includes a slider and a slide rail, the slider is connected to the cantilever, and the slide rail is located inside the frame and adapted to the slider.

[0011] The above-mentioned moxibustion smoke exhaust pipe has a longitudinal drive component including a frame plate, a second motor, a shaft, a drum, and a sling. The frame plate is placed horizontally on top of the second bend, the shaft is located inside the frame plate and has a second motor at one end, the drum is symmetrically located on the upper part of the shaft, one end of the sling is connected to the drum, and the other end is fastened to the end of the vertical hose.

[0012] The aforementioned moxibustion smoke exhaust duct also includes a guide wheel in its longitudinal drive assembly. The guide wheel is located on the upper part of the frame plate and provides rolling support for the suspension cable.

[0013] The aforementioned moxibustion smoke exhaust duct has a circumferential drive component including a third motor and gears. The third motor is vertically mounted on the upper part of the frame connected to the wall. The gears are divided into a driving gear, a variable speed gear, and a driven gear. The driving gear is located on the upper part of the output shaft of the third motor, the driven gear is located at the end of the frame, and the variable speed gear is mounted on the upper part of the frame through a bushing and meshes with the driving gear and the driven gear on both sides respectively.

[0014] The aforementioned moxibustion smoke exhaust pipe has a shaft cylinder at the end of the frame that is connected to the frame base via a bearing, and a driven wheel is provided at the lower end of the shaft cylinder.

[0015] The above-mentioned moxibustion smoke exhaust pipe has its two ends of the horizontal flexible tube connected to the first bend and the second bend via clamps.

[0016] The above-mentioned moxibustion smoke exhaust pipe has its upper end of the vertical flexible tube connected to the second bend pipe by a clamp.

[0017] The aforementioned moxibustion smoke exhaust pipe is secured to the upper part of the drum by rivets.

[0018] The beneficial effects of this utility model are:

[0019] 1. Flexible Adjustment and Precise Smoke Exhaust: By setting up horizontal, vertical, and circumferential drive components, the smoke exhaust duct achieves flexible adjustment in three dimensions: horizontal, vertical, and circumferential. The horizontal drive component allows the flexible horizontal hose to extend and retract according to the horizontal distance between the moxibustion device and the wall, ensuring that the smoke exhaust duct is accurately aligned with the smoke-generating area. The vertical drive component controls the extension and retraction of the vertical hose to adapt to changes in the layout of moxibustion devices or venues at different heights, ensuring that the smoke exhaust duct always maintains a suitable smoke exhaust height. The circumferential drive component drives the entire smoke exhaust duct to rotate circumferentially, further adjusting the smoke exhaust direction to ensure efficient smoke exhaust. This multi-dimensional and all-round adjustment function greatly improves the adaptability and smoke exhaust effect of the smoke exhaust duct, effectively solving the problem of poor adjustment flexibility of existing smoke exhaust ducts.

[0020] 2. Simple and efficient operation: Each drive component is rationally designed and easy to operate. In the horizontal drive component, the first motor drives the screw to rotate, which in turn drives the cantilever to move within the frame through the screw sleeve, realizing the extension and retraction of the horizontal flexible hose. In the vertical drive component, the second motor drives the shaft to rotate, and the drum winds up or unwinds the sling, controlling the extension and retraction of the vertical flexible hose. In the circumferential drive component, the third motor drives the drive wheel to rotate, which in turn drives the driven wheel to rotate through the speed-changing wheel, causing the frame to rotate the exhaust pipe circumferentially. Operators only need to control the corresponding motor switches to easily adjust the position of the exhaust pipe without the need for complicated disassembly and assembly using special tools, greatly reducing the difficulty of operation and improving work efficiency.

[0021] 3. Stable Structure and Reliable Safety: The structural design fully considers stability and safety. In the lateral drive assembly, the cooperation of slide rails and sliders ensures the smooth movement of the cantilever within the frame, preventing swaying. In the longitudinal drive assembly, the slings are supported by the rolling of guide wheels, reducing friction and making the extension and retraction of the vertical hose smoother. The guide wheels also stabilize the slings. In the circumferential drive assembly, the variable speed wheel not only adjusts the transmission ratio but also enhances transmission stability. Furthermore, all connections between components use reliable methods such as clamp connections and bolt connections, ensuring the overall structural stability of the exhaust duct. During exhaust, it can withstand a certain amount of suction and its own weight without loosening or deformation, effectively eliminating safety hazards and extending the service life of the exhaust duct.

[0028] The moxibustion smoke exhaust duct involved in this embodiment has an ingenious overall structural design, possessing multi-dimensional adjustment functions such as lateral and longitudinal extension and circumferential rotation. It can flexibly adapt to the needs of moxibustion smoke exhaust positions in different locations, effectively improving the smoke exhaust effect. Figure 1-4 As shown, the exhaust duct mainly consists of a bend for basic support, a horizontal drive assembly 5, a longitudinal drive assembly 6, and a circumferential drive assembly 7. The bend is divided into a first bend 1 and a second bend 2, which are connected by a horizontal flexible hose 3. The other end of the second bend 2 is connected to a vertical flexible hose 4. The horizontal drive assembly 5 is used to control the extension and retraction of the horizontal flexible hose 3, the longitudinal drive assembly 6 is used to control the extension and retraction of the vertical flexible hose 4, and the circumferential drive assembly 7 is used to drive the entire horizontal drive assembly 5 and the bend to rotate circumferentially, thereby realizing the flexible adjustment of the exhaust duct in space.

[0029] The bend is the basic support structure of the smoke exhaust duct, consisting of a first bend 1 and a second bend 2. The side of the first bend 1 has a bracket for connection to the wall, which initially fixes the first bend 1 to the wall, providing a stable support foundation for the entire smoke exhaust duct. A horizontal flexible hose 3, which provides lateral expansion and contraction, is arranged between the first bend 1 and the second bend 2. Made of flexible material, the horizontal flexible hose 3 has good extensibility and flexibility, allowing it to expand and contract under the action of the lateral drive component 5, thereby adjusting the length of the smoke exhaust duct in the horizontal direction. Both ends of the horizontal flexible hose 3 are connected to the first bend 1 and the second bend 2 respectively via clamps. This connection method is simple and reliable, easy to install and disassemble, and also ensures the sealing of the connection to prevent smoke leakage. At the other end of the second bend 2, a vertical flexible hose 4, which provides longitudinal expansion and contraction, is arranged vertically downwards. Also made of flexible material, the vertical flexible hose 4 can expand and contract vertically under the action of the longitudinal drive component 6 to adapt to smoke exhaust needs at different heights. The upper end of the vertical flexible hose 4 is also connected to the second bend 2 via clamps to ensure the stability and sealing of the connection.

[0030] The lateral drive assembly 5 is a key component for controlling the extension and retraction of the horizontal flexible hose 3. It mainly includes a frame 51, cantilever 52, support tube 53, slide rod 54, first motor 55, screw 56, screw sleeve 57, slide rail 58, and slider 59. The frame 51 is located below the first bend 1 and connected to it by bolts. This connection method makes the frame 51 and the first bend 1 form a whole, enhancing the stability of the structure. One side of the frame 51 is connected to the wall via a hinged bracket. This hinged method allows the frame 51 to rotate circumferentially within a certain range, facilitating the subsequent circumferential drive assembly 7. The work provides a foundation. A reciprocating cantilever 52 is arranged inside the frame 51. The cantilever 52 can perform linear reciprocating motion inside the frame 51, thereby realizing the telescopic operation of the horizontal flexible hose 3. A screw 56, connected to the frame 51 along its axial direction via a bearing seat, is arranged inside the frame 51. The screw 56 can rotate stably under the support of the bearing seat. A first motor 55, which drives the screw 56 to rotate via a coupling, is also arranged inside the frame 51. The first motor 55 provides power for the rotation of the screw 56. A threaded sleeve 57, meshing with the screw 56, is arranged inside the cantilever 52. When the first... When the motor 55 drives the screw 56 to rotate, the sleeve 57 moves along the axial direction of the screw 56, thereby driving the cantilever 52 to produce linear reciprocating motion inside the frame 51. This transmission method via the screw 56 and sleeve 57 has the advantages of high transmission accuracy and good stability, ensuring smooth and reliable extension and retraction of the cantilever 52. To improve the smoothness of the reciprocating motion of the cantilever 52, a slider 59 connected to it is arranged below the cantilever 52, and a slide rail 58 adapted to the slider 59 is arranged inside the frame 51 along its axial direction. When the cantilever 52 moves inside the frame 51... At the same time, the slider 59 will slide back and forth along the surface of the slide rail 58, thereby avoiding direct contact wear between the cantilever 52 and the frame 51, reducing friction, and making the reciprocating movement of the cantilever 52 smoother. At the same time, the cooperation between the slide rail 58 and the slider 59 can also play a guiding role, ensuring that the movement direction of the cantilever 52 is accurate. Meanwhile, support tubes 53 and slide rods 54 can be added on both sides of the horizontal flexible tube 3 to support and prevent deformation from falling. One end of the support tube 53 is connected to the first bent tube 1, and one end of the slide rod 54 is connected to the second bent tube 2. The support tube 53 and the slide rod 54 are fitted together in a sliding connection.

[0031] The longitudinal drive assembly 6 is used to control the extension and retraction of the vertical flexible hose 4. It mainly includes a frame plate 61, a second motor 62, a shaft 63, drums 64, slings 65, and guide wheels 66. The frame plate 61 is horizontally positioned on top of the second bend 2, providing a mounting base for the other components of the longitudinal drive assembly 6. A shaft 63, connected to the frame plate 61 via a bearing seat, is horizontally positioned on its upper part. The shaft 63 can rotate stably under the support of the bearing seat. A second motor 62, connected to one end of the shaft 63 via a coupling, provides power for the rotation of the shaft 63. Two drums 64, symmetrically arranged and keyed to the upper part of the shaft 63, rotate synchronously with the shaft 63. A sling 65, which can be wound around, is fixed to the upper part of the drum 64 by rivets. The other end of the sling 65 is connected to the end of the vertical flexible hose 4. When the second motor 62 drives the shaft 63 to rotate, the drum 64 will rotate accordingly, thereby performing winding or unwinding operations on the sling 65. When the drum 64 winds up the sling 65, the vertical hose 4 will contract under the tension of the sling 65; when the drum 64 unwinds the sling 65, the vertical hose 4 will unfold under its own weight. In this way, the vertical hose 4 can be adjusted for extension and retraction in the vertical direction. In order to avoid friction between the sling 65 and the frame plate 61, which would cause the sling 65 to wear or break, a guide wheel 66 is arranged on the upper part of the frame plate 61 to provide rolling support for the sling 65. The guide wheel 66 can provide support and guidance during the movement of the sling 65, reduce the friction between the sling 65 and the frame plate 61, extend the service life of the sling 65, and also ensure the smoothness of the extension and retraction operation of the vertical hose 4.

[0032] To facilitate adjustment of the exhaust duct's spatial position and better adapt to the required exhaust locations within the site, a circumferential drive assembly 7 is arranged at the lower end of the horizontal drive assembly 5 to drive its circumferential rotation. The circumferential drive assembly 7 mainly includes a third motor 71 and gears. The third motor 71 is vertically arranged on the upper part of a frame connected to the wall, providing power for circumferential rotation. A gear for driving the frame 51 to rotate circumferentially is arranged on one side of the third motor 71. The gear consists of a driving gear 72, a variable speed gear 73, and a driven gear 74. The driving gear 72 is keyed to the upper part of the output shaft of the third motor 71. When the third motor 71 starts, the driving gear 72 rotates synchronously with the output shaft. A shaft sleeve connected to the frame base via bearings is arranged at the end of the frame 51. The driven gear 74 is bolted to the lower end of the shaft sleeve, connecting the frame 51 and the driven gear 74 through the shaft sleeve. The driving wheels 74 are connected together, so that the frame 51 can rotate synchronously with the rotation of the driven wheel 74. The variable speed wheel 73 is arranged on the upper part of the frame through a bushing. The two sides of the variable speed wheel 73 are respectively meshed with the driving wheel 72 and the driven wheel 74. The number of teeth of the variable speed wheel 73 is 2 to 5 times that of the driving wheel 72, and the number of teeth of the variable speed wheel 73 is the same as that of the driven wheel 74. This gear transmission design can reduce the high speed from the third motor 71 to a suitable speed for the frame 51 to rotate, so as to achieve smooth circumferential rotation adjustment. When the third motor 71 drives the driving wheel 72 to rotate, the driving wheel 72 drives the driven wheel 74 to rotate through the variable speed wheel 73, thereby causing the frame 51 to drive the entire smoke exhaust pipe to rotate circumferentially, thereby adjusting the spatial position of the smoke exhaust pipe so that it can be accurately aligned with the smoke emission point generated by moxibustion, thus improving the smoke exhaust efficiency.

[0033] Working Principle: In actual use, when the horizontal length of the exhaust pipe needs to be adjusted, the first motor 55 is started. The first motor 55 drives the screw 56 to rotate, and the screw sleeve 57 drives the cantilever 52 to move inside the frame 51, thereby realizing the extension and retraction of the horizontal flexible hose 3, and thus adjusting the length of the exhaust pipe in the horizontal direction. When the vertical height of the exhaust pipe needs to be adjusted, the second motor 62 is started. The second motor 62 drives the shaft 63 to rotate, and the drum 64 winds up or unwinds the sling 65, causing the vertical flexible hose 4 to contract or expand under the drive of the sling 65, thereby adjusting the height of the exhaust pipe in the vertical direction. When the spatial position of the exhaust pipe needs to be adjusted, the third motor 71 is started. The third motor 71 drives the frame 51 to rotate circumferentially through gear transmission, thereby causing the entire exhaust pipe to rotate and accurately align with the emission point of the smoke generated by moxibustion. Through the coordinated adjustment of the horizontal, vertical and circumferential directions, the exhaust pipe can flexibly adapt to the needs of the moxibustion smoke emission position in different venues, effectively improving the smoke emission effect and providing good air quality assurance for the moxibustion treatment environment.

[0034] Before installing the moxibustion exhaust duct, a detailed survey of the moxibustion operation site is required to determine the main placement location of the moxibustion equipment and the approximate area where smoke is generated. The load-bearing capacity of the wall and the available installation space must also be considered. Based on the survey results, a suitable wall location should be selected as the fixing point for the exhaust duct, ensuring that the location meets the installation requirements without excessively interfering with the normal use of the site. First, the first bend 1 is fixed to the wall using a bracket. Then, one end of the horizontal flexible hose 3 is connected to the first bend 1 using a clamp. Finally, the second bend 2 is connected to the other end of the horizontal flexible hose 3 using a clamp. Finally, connect the upper end of the vertical hose 4 to the second bend 2 using clamps. During assembly, pay attention to the tightness and sealing of the connections between components to prevent flue gas leakage. Then connect the first motor 55 in the horizontal drive assembly 5, the second motor 62 in the vertical drive assembly 6, and the third motor 71 in the circumferential drive assembly 7 to the power supply. When connecting electrical circuits, strictly follow electrical safety regulations to ensure that the circuit connections are firm and well-insulated, avoiding safety hazards such as leakage and short circuits. At the same time, equip each motor with a corresponding control switch for convenient subsequent operation and control.

[0035] When the position of the moxibustion device does not match the initial horizontal length of the exhaust duct, the horizontal length needs to be adjusted. The operator starts the first motor 55 by controlling the control switch of the first motor 55 in the horizontal drive assembly 5. The first motor 55 drives the screw 56 to rotate, and the screw sleeve 57 drives the cantilever 52 to move inside the frame 51. If it is necessary to increase the horizontal length of the exhaust duct, the first motor 55 rotates forward, and the screw sleeve 57 drives the cantilever 52 to extend outward, and the horizontal flexible tube 3 extends accordingly. If it is necessary to decrease the horizontal length of the exhaust duct, the first motor 55 rotates in reverse, and the screw sleeve 57 drives the cantilever 52 to retract inward, and the horizontal flexible tube 3 retracts accordingly. During the adjustment process, the operator should closely observe the movement of the cantilever 52 to ensure that its movement is smooth and without jamming. At the same time, the operator can judge whether the adjustment has achieved the expected effect by observing the extension and contraction of the horizontal flexible tube 3. When the horizontal length of the exhaust duct is adjusted to the appropriate position, the control switch of the first motor 55 is turned off.

[0036] When the height of the moxibustion device changes or the vertical height of the exhaust pipe needs to be adjusted to better meet exhaust requirements, the vertical height is adjusted. The operator starts the second motor 62 by controlling the control switch of the second motor 62 in the longitudinal drive assembly 6. The second motor 62 drives the shaft 63 to rotate, and the drum 64 winds up or unwinds the sling 65. If it is necessary to increase the vertical height of the exhaust pipe, the second motor 62 rotates forward, the drum 64 winds up the sling 65, and the vertical hose 4 contracts under the tension of the sling 65. If it is necessary to decrease the vertical height of the exhaust pipe, the second motor 62 rotates in reverse, the drum 64 unwinds the sling 65, and the vertical hose 4 unfolds under its own weight. During the adjustment process, it is important to observe the expansion and contraction of the vertical hose 4 to ensure smooth movement and avoid overstretching or compression. When the vertical height of the exhaust pipe is adjusted to the appropriate position, the control switch of the second motor 62 is turned off.

[0037] When the position of the moxibustion device shifts or the exhaust direction of the smoke duct needs to be changed, circumferential position adjustment is performed. The operator starts the third motor 71 by controlling the control switch of the third motor 71 in the circumferential drive assembly 7. The third motor 71 drives the drive wheel 72 to rotate, and the drive wheel 72 drives the driven wheel 74 to rotate through the gear wheel 73, thereby causing the frame 51 to drive the entire smoke duct to rotate circumferentially. During the adjustment process, the operator should slowly rotate the third motor 71 and observe the rotation of the smoke duct to ensure that it rotates smoothly without shaking. At the same time, pay attention to the outlet direction of the smoke duct to ensure that it is accurately aligned with the smoke emission point generated by moxibustion. After the circumferential position of the smoke duct is adjusted to the appropriate position, turn off the control switch of the third motor 71.

[0038] After adjusting the position of the exhaust duct, activate the exhaust equipment in the moxibustion area. This equipment can be a fan, etc. The suction generated by the fan draws the smoke produced during moxibustion into the exhaust duct. During the exhaust process, the operator must closely monitor the exhaust effect, observe for any smoke leaks in the exhaust duct, and check if the smoke is discharged smoothly at the duct outlet. If the exhaust effect is poor, it may be due to inaccurate adjustment of the exhaust duct position or a malfunction of the exhaust equipment. In this case, the operator can fine-tune the position of the exhaust duct again based on the actual situation, or check the operating status of the exhaust equipment and troubleshoot any problems promptly. After the moxibustion operation is completed, turn off the exhaust equipment. Then, if necessary, the exhaust duct can be restored to its initial state or kept in its current state for future use. If the exhaust duct needs to be disassembled, disassemble each component in reverse order of installation and store the components properly for future installation.

[0039] In summary, the moxibustion smoke exhaust pipe involved in this embodiment, through its ingenious structural design and multi-dimensional adjustment function, achieves flexible adjustment of the smoke exhaust pipe in spatial position. It has the advantages of simple structure, convenient operation, high adjustment precision, and good smoke exhaust effect, and has broad market application prospects.
