Description

Technical Field

[0001] This utility model relates to the field of moxibustion technology, specifically to a wall-mounted moxibustion smoke purification system. Background Technology

[0002] Moxibustion is a traditional Chinese medicine therapy that involves burning moxa wool on specific areas of the body to generate heat that stimulates acupoints, regulating the balance of Yin and Yang, Qi and Blood in the internal organs, and addressing imbalances in the body's constitution and disease response. For a long time, moxibustion has been used to treat various ailments due to its simplicity, convenience, ease of use, and affordability.

[0003] However, moxibustion is not as widely used in clinical practice as acupuncture, largely because the process inevitably produces odors and releases large amounts of smoke, polluting the treatment environment and posing certain unresolved safety hazards. With increasing environmental and health awareness, the issue of moxibustion smoke has become a significant obstacle to the inheritance and development of moxibustion therapy.

[0004] Clinically, the emission of moxibustion smoke currently relies mainly on measures such as opening windows for ventilation and central smoke extraction systems. However, most hospital acupuncture departments have rudimentary equipment, and ventilation and insulation cannot be simultaneously ensured. Only a few well-equipped tertiary hospitals or high-end clinics have the commonly available vertical smoke extraction systems. Currently, various vertical smoke extraction systems on the market connect the exhaust pipe to the moxibustion smoke purifier. Their advantage is that they can be moved as needed, but smoke extraction is incomplete, the internal filter has a short lifespan, and the smoke purifier is bulky, occupying valuable clinic space. Alternatively, there is the option of installing exhaust ducts, a concept derived from the smoke extraction devices in Korean barbecue restaurants. The exhaust vent can be adjusted by sliding along a track to cover from head to toe. However, such devices are cumbersome and have only one exhaust vent, suitable only for patients undergoing moxibustion while lying down, and not suitable for multi-site moxibustion. Therefore, the safe emission of moxibustion smoke is a key factor affecting the clinical application of moxibustion therapy, and solving this problem is urgent.

[0005] Chinese utility model patent application number 201620000610.6 discloses a moxibustion smoke emission device, including a smoking hose, a flue, and a central smoke exhaust device. Multiple branch smoke pipes are provided on the side wall of the flue, and these branch smoke pipes are connected to the exhaust hose via four-way fittings. During moxibustion, moxibustion smoke is inhaled through an adjustable smoke inlet and discharged along the smoking hose and flue to the central smoke exhaust device. This patent avoids the drawbacks of traditional moxibustion, improves the treatment environment for moxibustion, and avoids the safety hazards of medical personnel and patients inhaling moxibustion smoke. However, it also has the problem that the branch smoke pipes need to be manually operated, making it inconvenient to use.

[0006] Chinese utility model patent application number 202120415619.4 discloses a mobile moxibustion smoke exhaust device, including a moving track installed on the ceiling, a moving winch installed on the moving track, and a smoke exhaust device vertically connected to the moving winch via a hoisting line. The smoke exhaust device has an internal smoke exhaust duct. A smoke exhaust hood is connected to the bottom of the smoke exhaust device, and the smoke exhaust hood is connected to the inlet of the internal smoke exhaust duct of the smoke exhaust device. The smoke exhaust device has a smoke exhaust pipe, which is connected to an external purification device through a smoke exhaust outlet on the room wall or ceiling. This patent does not rely on manual operation; it only requires a handheld remote control, enabling remote operation, saving manpower, and making it more convenient to use. However, this patent uses a moving winch and a hoisting line to raise and lower the smoke exhaust hood. During the raising and lowering process, the smoke exhaust hood is prone to swaying, and the hoisting line may break after prolonged use and aging. Summary of the Invention

A second receiving groove 523 is provided at the bottom of the second through hole 521. A filter box 53 is detachably connected to the second receiving groove 523. By using the filter box 53, impurities in the smoke are initially removed. The main components that easily cause blockage of the exhaust pipe 6 are filtered by the filter box 53, making the exhaust pipe 6 less prone to blockage by components in the smoke, reducing the cleaning frequency of the flue and alleviating maintenance pressure.

[0041] In this embodiment, a smoke guide 54 is fitted inside the second sleeve 522. A filter cotton 55 is attached to the inner wall of the smoke guide 54, and the filter cotton 55 is embedded between the outer wall of the smoke guide 54 and the inner wall of the second sleeve 522. An annular protrusion 541 protrudes outward from the bottom outer edge of the smoke guide 54, and the annular protrusion 541 abuts against the bottom of the second sleeve 522. The filter cotton 55 can absorb smoke stains and impurities, making it easier to keep the inside of the exhaust pipe 6 clean and less prone to dust accumulation, thus reducing the need for frequent cleaning.

[0042] In this embodiment, the filter box 53 includes a bottom cover 531 and an annular mesh frame 532 embedded in the bottom cover 531. A third through hole 533 is formed in the middle of the annular mesh frame 532, and a fourth through hole 534 is formed in the middle of the bottom cover 531. An annular side groove 530 is formed at the bottom of the third through hole 533, and a filter screen 535 is embedded in the annular side groove 530. The bottom of the filter screen 535 abuts against the inner side wall of the bottom cover 531. Specifically, the inner side wall of the bottom cover 531 has a plurality of vertically arranged positioning blocks 536 arranged in a ring array. The outer side wall of the annular mesh frame 532 has positioning holes 537 corresponding to the positions of each positioning block 536, and each positioning block 536 is embedded in the corresponding positioning hole 537. The filter screen 535 can initially remove impurities in the smoke. The main components that easily cause blockage of the exhaust pipe 6 are filtered by the filter box 53, making the exhaust pipe 6 less likely to be blocked by components in the smoke, reducing the cleaning frequency of the exhaust pipe and alleviating the maintenance pressure.

[0043] In this embodiment, the inner top wall of the second receiving groove 523 is provided with an annular protrusion 524 protruding downwards, and the bottom of the annular protrusion 524 abuts against the top of the annular mesh frame 532. The above structure can form a filtration space between the annular mesh frame 532 and the smoke guide duct 54, thereby improving the filtration effect.

[0044] In this embodiment, the outer wall of the bottom cover 531 has at least two locking blocks 538 arranged in a ring. The second receiving groove 523 has an L-shaped slot 525 corresponding to the position of each locking block 538, and each locking block 538 can be rotated and locked into the corresponding L-shaped slot 525. The above structure facilitates the installation and removal of the filter box 53.

[0045] In this embodiment, a circuit board 31 is fixed inside the hoisting box 3, and a display screen 520 is embedded in the side wall of the second fixing base 52. A remote control receiver (not shown in the figure) is installed on the circuit board 31. The circuit board 31 is electrically connected to the exhaust fan 7, the electric push rod 8, the display screen 520, and the remote control receiver. Specifically, the display screen is a touch screen. By using the touch screen, the lifting and lowering operation and the smoke exhaust opening and closing can be performed manually by touch. By using the remote control receiver, the electric push rod 8 can be controlled remotely from a distance without contact to perform the lifting and lowering operation and the smoke exhaust opening and closing. Both operation methods are available, making it convenient to use.

[0046] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
