The present invention provides a brush head for cleaning electrically heated smoking articles for cleaning smoking articles with elongate heaters, for example, US patent 2015136154a1 by philips morris corporation discloses a smoking article for use in an aerosol generating device, comprising: an aerosol-forming substrate located at an upstream-most end of a smoking article; and a support element immediately downstream of the aerosol-forming substrate. The support element abuts the aerosol-forming substrate and the aerosol-forming substrate is configured to be pierceable by a heating element of the aerosol-generating device having a diameter between about 40% and about 70% of the diameter of the aerosol-forming substrate without significant deformation of the smoking article. The support element is configured to inhibit downstream movement of the aerosol-forming substrate during insertion of the heating element of the aerosol-generating device into the aerosol-forming substrate. Smoking articles for use with such smoking articles, as described in US2015163859a1 of philips morris corporation, the housing of the aerosol generating device defining a cavity open at the proximal (or mouth) end for receiving an aerosol generating article for consumption; an aerosol-forming substrate is pushed inside the housing to be in heat-transferable proximity with a heater inserted into an aerosol-forming article, the release of a selected volatile compound being controlled while the release of an undesired compound is controlled by controlling the maximum operating temperature of the electrically heated aerosol-generating system below a selected value.

As shown in FIG. 1, the present embodiment provides a brush head for cleaning an electrically heated smoking article. In some embodiments, the brush head may be configured with a drive, such as a micro motor, or the like, for driving it 360 degrees. When the toothbrush is used, the brush head is inserted into a cigarette accommodating cavity of a smoking set, and the brush head moves in a 360-degree rotating motion, a left-right oscillating motion and/or an up-down motion at a certain speed under the control of the driver.

Wherein, the electric heating smoking set comprises a containing cavity for containing cigarettes, and the brush head comprises at least one bracket 1 inserted into the containing cavity, wherein the number of the brackets 1 is determined according to the requirement. Each support 1 comprises at least one top main body 11 corresponding to the bottom wall of the accommodating cavity and at least one side extension body 12 extending along the depth direction of the accommodating cavity, first bristles 21 are arranged on each top main body 11, second bristles 22 are arranged on each side extension body 12, and the length of the first bristles 21 extending from the top main body 11 is larger than the length of the second bristles 22 extending from the side extension bodies 12.

Wherein, the first brush 21 and the second brush 22 extend radially from the top body 11 and the side extension 12, respectively.

The top body 11 and the side extension 12 are preferably integrally formed. The top body 11 and the side extension 12 may be connected by welding or the like.

The first bristles 21 and the second bristles 22 respectively include at least bristles of thermoplastic material and/or bristles of absorbent material. It includes but is not limited to the following cases: the first bristles 21 and the second bristles 22 each include bristles of thermoplastic material and bristles of absorbent material; alternatively, the first bristles 21 are bristles of thermoplastic material and the second bristles 22 are bristles of absorbent material; alternatively, the second bristles 22 are bristles of thermoplastic material, and the first bristles 21 are bristles of absorbent material; alternatively, the first bristles 21 and the second bristles 22 are both bristles of thermoplastic material; alternatively, the first bristles 21 and the second bristles 22 are both bristles of an absorbent material.

The adsorptive material can clean away residual liquid in the cigarette accommodating cavity, such as oily liquid generated by heating smoke substances, and can carry some cleaning solvents, such as 2-butoxyethanol, glycol ether, mineral oil, ethyl acetate, isopropanol, ethanol, isoamyl acetate, isoamyl butyrate, ethyl hexanoate and the like, so as to soften, dissolve and/or decompose deposits or residues, particularly dirt which is difficult to clean, such as residue formed by drying and solidifying tar after being heated and tightly adsorbing on a heater or the accommodating cavity. The cleaning solvent weakens the adsorption force between the sediments or residues and the smoking set, and the sediments or residues and the smoking set are easy to fall off by matching with the friction caused by the rotation of the bristles, so that the cleaning purpose is achieved. The thermoplastic material brush hair has the hardness and the elasticity that are bigger than the adsorptivity material brush hair, and it can produce the frictional force that is bigger than the adsorptivity material brush hair in the circumferential motion process, makes the residue drop more easily, and two kinds of brush hairs cooperate and use, can full play respective characteristics and compensate the defect of single brush hair, and the cleaning performance who plays strengthens greatly.

The thermoplastic material comprises a thermoplastic plastic material and a thermoplastic rubber material; the adsorptive material comprises foamed plastic, foamed rubber, natural fiber and artificial fiber. Thermoplastic rubber materials (TPR materials) including Thermoplastic vulcanizates (TPV), Thermoplastic polyurethane elastomers (TPU); the thermoplastic material comprises: ethylene-vinyl acetate copolymer (EVA), Polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), polylactic acid (PLA), Polystyrene (PS), nylon (PA), Polycarbonate (PC), Polyurethane (PU).

In some embodiments, the top body 11 is an arcuate bar and the side extensions 12 are straight bars that meet the ends of the arcuate bar. In other embodiments, top body 11 is Π -shaped. In other embodiments, the side extensions 12 may be square, oval, wavy, etc.

In some embodiments, the angle between the top body 11 and the side extension 12 at the intersection position may be 0 °, and the angle may be substantially inverted U-shaped, in which case the number of the brackets 1 may be two or three, thereby enclosing the heating element therein. In other embodiments, the angle between the top body 11 and the side extension 12 is 90 °. In other embodiments, the angle between the top body 11 and the side extension 12 is between 0 ° and 90 °, such as 60 °, 80 °, etc.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
