When the pre-filter tube 800 is detached, the smoke exhaust tube is pulled (i.e., the smoke exhaust tube deviates from the bent tube part 820 along the axial direction of the retainer ring 211 a), so that the smoke exhaust tube is separated from the bent tube part 820, the end part of the smoke exhaust tube is buckled on the retainer ring 211a, specifically, the smoke exhaust tube deviates from the pre-filter tube 800, and the smoke exhaust tube cannot influence the axial movement of the pre-filter tube 800 in the axial direction of the pre-filter tube 800, namely, the smoke exhaust tube cannot prevent the pre-filter tube 800 from deviating from the tool head body 210. After the new pre-filter tube 800 is inserted into the tool head body 210, the smoke exhaust tube is connected to the bent tube portion 820 through the collar 211a (i.e., the smoke exhaust tube is close to the bent tube portion 820 in the axial direction of the collar 211 a). The embodiments of the invention can solve the technical problem that the preposed filter tube 800 is shielded by the smoke exhaust tube during drawing, and can solve the technical problem that the smoke exhaust tube is temporarily stored and hung after being detached.

In the present invention, the straight tube portion 810 means that its axis is a straight line or an approaching straight line; the straight tube portion 810 may also be a reducer, i.e. the inner diameter and/or outer diameter of the straight tube portion 810 may have a gradual change/abrupt change along the axial direction, for example, the inner wall of the straight tube portion 810 is provided with a groove around the axis, and the groove is used for accommodating the adsorbent and the filter material. The bent pipe portion 820 means that its axial line is significantly bent (i.e., significantly extends along a curve).

In some embodiments of the invention, the straight tube portion 810 and the bent tube portion 820 are detachably connected. The embodiments of the invention can solve the technical problems that the easily-polluted parts need to be smaller and the physical therapy use cost needs to be lower. In some embodiments of the present invention, the prefilter pipe 800 further comprises a soft sleeve 830, one end of the bent pipe portion 820 near the straight pipe portion 810 is provided with a ring groove, an inner wall of one end of the soft sleeve 830 is provided with a flange for snapping the ring groove, and the other end of the soft sleeve 830 is used for embracing one end of the straight pipe portion 810 near the bent pipe portion 820. The embodiments of the invention can solve the technical problems that frequently replaced parts need to be easily detached and the connection of the continuously utilized parts needs to be firm.

In some embodiments of the present invention, the straight tube portion 810 is made of one of PPS plastic, PPS plus glass fiber, nylon plus glass fiber, stainless steel, aluminum alloy, and tin plate. The embodiments of the invention can solve the technical problem of material cost of frequently replaced parts.

In some embodiments of the invention, the filter structure comprises one or more of an ash barrier layer, a grease adsorbing layer, an air purifying layer, and an odor adsorbing layer. The embodiments of the invention can solve the technical problem of oil, smoke and/or peculiar smell generated by the combustion of the physiotherapy material.

The ash barrier layer can be steel mesh, aluminum mesh, sponge, nylon mesh, cotton mesh, non-woven fabric and the like; the grease adsorption layer can be classic oil absorption cotton, honeycomb porous plate and the like; the air purification layer can be HEPA, activated carbon and the like; the peculiar smell adsorption layer can be a high-molecular porous material layer, a silica gel layer, a ceramic layer, an active carbon layer, a diatomite layer and the like.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
