Compared with the prior art, the invention has the beneficial effects that: the user lies on the bed body, the head of the user is rested on the pillow, and the moxibustion cabin slides to the body treatment part of the user.

During the moxa stick of will pointing to then inserts the main part pipe on the moxa-moxibustion unit, pull out the sealed lid on the moxa-moxibustion storehouse relevant position to insert the moxa-moxibustion unit in the moxa-moxibustion slot, annular negative pressure groove is relative with the smoking mouth this moment, and annular air channel is relative with the negative pressure mouth.

When the negative pressure source is communicated with the smoke exhaust joint, smoke and ash generated by burning the moxa sticks enter the negative pressure source from the mesh plate through the smoke suction holes, the smoke suction ports, the smoke suction channels and the smoke exhaust joint under the action of negative pressure, so that the treatment of the smoke and the ash is realized.

When the negative pressure source is communicated with the negative pressure joint, the suction force generated by the negative pressure is transmitted to the annular vent groove through the negative pressure channel a, the negative pressure channel b and the negative pressure port, the elastic extension tube is communicated with the annular vent groove through the negative pressure vent hole, and finally the elastic extension tube moves downwards due to the suction of the negative pressure; the push head on the elastic extension tube is clamped with the moxa stick, so that the moxa stick moves downwards along with the elastic extension tube; when the negative pressure source is not communicated with the negative pressure joint, the elastic extension tube moves upwards under the action of the elasticity of the elastic extension tube, but the position of the moxa stick is not changed along with the rising of the elastic extension tube because the chuck on the moxa stick clamping ring is mutually clamped with the moxa stick.

When the centrifugal exhaust fan as a negative pressure source works, the motor drives the centrifugal fan blades to rotate, so that negative pressure is generated at the air suction through hole, smoke and ash extracted from each moxibustion unit are discharged from the smoke discharge pipe joint, and finally, the smoke and the ash are discharged to the outside through the smoke discharge pipe connected with the smoke discharge pipe joint.

The driving gear at the tail end of the motor output shaft is meshed with the reduction gear a to perform primary speed reduction, the reduction gear b which is coaxially and fixedly connected with the reduction gear a is meshed with the driven gear on the circular valve disc to perform secondary speed reduction, the circular valve disc rotates slowly, the gating valve port is communicated with the air suction joints intermittently, and finally the air suction joints generate negative pressure intermittently.

When the negative pressure filter assembly as a negative pressure source works, the motor rotates to drive the magnetic turntable a to rotate, the magnetic turntable a and the magnetic turntable b attract each other, so that the magnetic turntable b drives the water wheel to rotate, negative pressure is generated near the water wheel due to the rotation of the water wheel, gas in the ventilating pipe flows from top to bottom, and smoke and ash in the moxibustion cabin enter the ventilating pipe through the gate valve; when gas passes through the pneumatic wind wheel, the gas can push the gas wind wheel to rotate, the pneumatic wind wheel drives the valve plate to rotate, the gating valve hole on the valve plate is intermittently communicated with each air exhaust joint, only a small amount of moxibustion units are communicated with the negative pressure filtering component at the same time, so that the smoke suction hole can form large negative pressure, and smoke and ash generated by moxa sticks can be fully sucked away.

The water in the inner diversion barrel rotates at high speed along the barrel wall of the inner diversion barrel under the drive of the water wheel to form a dynamic water film, so that after the smoke flows out of the vent pipe, the smoke rotates along with the water film on the inner wall of the inner diversion barrel, the smoke and the water film are contacted, particulate matters and ash in the smoke are dissolved in the water, the water on the upper part of the water film reaches a side leakage hole, part of the water enters between the outer barrel and the inner diversion barrel through the side leakage hole, most of the particulate matters are removed through the absorption of filter cotton, the filtered water flows to the bottom of the outer barrel, the other part of the water and the filtered gas enter the upper end of the exhaust hood through the exhaust hole, the gas flows to the outside through the exhaust pipe joint through the exhaust pipe, the water from bottom to top flows into the spray plate through the exhaust plate, and uniformly drops into the inner diversion barrel from the, the filtering effect is enhanced; under the action of centrifugal force generated by water around the water wheel, water at the bottom in the outer barrel is thrown into the flow guiding inner barrel through the backflow hole a, the backflow hole b and the backflow hole c in sequence so as to carry out next circulation.
