The shape of the main body 110 is not limited in this design, and the main body 110 may be designed into any suitable shape according to practical needs, for example, a substantially cylindrical shape as shown in fig. 1 or a substantially prismatic shape as shown in fig. 2. When installed in a blower, the blower provides an installation space (e.g., the installation cavity 220 in the embodiments below) that provides an installation wall (e.g., the inner cavity wall of the installation cavity 220 in the embodiments below). Based on this, at least part of the outer wall of the main body 110 may be adapted to the shape of the installation wall surface to be designed in a straight surface shape, a cambered surface shape or a concave-convex surface shape, so as to increase the adaptation degree between the main body 110 and the installation wall surface, so that the connection between the two is more compact.

The size of the main body 110 is not limited in this design, and can be specifically adjusted according to the size of the installation space provided by the blower:

in one embodiment, the dimensions of the main body 110 may be designed to correspond to a specific, different specification series, depending on the different installation spaces provided by the blower, such that there is a one-to-one correspondence in dimensions between the main body 110 and the blower.

The first support structure 140 may be provided in one or at least two, and may be supported between any surface of the body 110 and the installation wall surface, according to actual needs. To improve the fit of the first support structure 140, in one embodiment, the first support structure 140 is made of an elastic material. The first support structure 140 may be embodied as a spring member, a rubber block, a foam cushion, or the like. The first supporting structure 140 supported by the elastic material can form different thicknesses under different deformation degrees, so that different dimensional deviations between the outer surface of the main body 110 and the mounting wall surface can be adapted, and the first supporting structure 140 and the main body 110 and the first supporting structure 140 are elastically abutted against the mounting wall surface, so that the liquid storage part 100 can be effectively protected.

Of course, the material of the main body 110 is not limited in this design, and the main body 110 may be made of, for example, ceramic material, soft rubber material, etc. according to practical needs. Wherein, when the main body 110 is made of a rigid material, the whole body of the main body 110 is formed with sufficient structural strength to effectively protect the hair care substances stored therein; on the contrary, when the main body 110 is made of an elastic material, at least the outer wall of the main body 110 can be elastically deformed under the action of an external force, so that the compensation of the dimensional deviation between the main body 110 and the installation wall surface can be achieved without additionally providing the first support structure 140 as described above.

In addition, in an embodiment, the liquid storage portion 100 further includes an adsorption structure 130, and the adsorption structure 130 is accommodated in the cavity 111 and is used for adsorbing the hair care substance. The adsorption structure 130 is, for example, sponge, absorbent cotton, polyester, etc., and is capable of adsorbing and gathering the hair care substance in liquid state, so as to prevent the hair care substance in liquid state from flowing or overflowing in the cavity 111 of the main body 110 in an disordered manner.

Further, in an embodiment, at least a portion of the adsorption structure 130 is disposed adjacent to the opening 112, and the rest of the adsorption structure 130 may be disposed near the bottom of the cavity 111, so that after the adsorption structure 130 adsorbs the hair care material and the hair care material is uniformly impregnated in the adsorption structure 130, the hair care material in the cavity 111 is guided to be adjacent to the opening 112, so that, especially when the capacity of the hair care material in the cavity 111 is low, it is still ensured that sufficient hair care material is accumulated at the opening 112, so that the hair care material can be more quickly and completely discharged through the opening 112 when driven by an external force.

The openings 112 of the main body 110 may be provided in one or more, wherein when the openings 112 are provided in a plurality, the orientations of the plurality of openings 112 may be the same or may be at least partially different. Particularly when at least some of the plurality of openings 112 are oriented differently, the hair care substance can be discharged from multiple directions simultaneously, which facilitates rapid generation of the hair care substance during operation of the hair dryer.

The fine filter structure 120 is capped at one or more openings 112 such that the hair care material discharged through any of the openings 112 can pass through the fine filter structure 120. It will be appreciated that the fine filter structure 120 can serve three functions, one of which is to filter out other impurities and pass substantially only the hair care material; secondly, the passing hair care substances can be thinned when external force driving, namely working state is achieved; thirdly, when no external force is used for driving, namely, in a non-working state, the fine filtering structure 120 causes a certain obstruction to the hair care substances entering and exiting the cavity 111, thereby helping to slow down the volatilization speed of the hair care substances from the cavity 111 and reducing the consumption of the hair care substances. Wherein, the types of other impurities are different according to the specific protection requirements of the hair care substance, for example, when the hair care substance is an essential oil product and moisture doping is reduced as much as possible during the preservation process, the fine filtration structure 120 can be embodied as a waterproof and breathable structure, such as a waterproof and breathable film; when the hair care material is a solvent-based product and it is desired to supplement a certain amount of water to maintain a desired concentration during storage, the fine filter structure 120 may be embodied as a moisture permeable and breathable structure, such as a moisture permeable and breathable film; when the hair care material is protected from light during its storage, the fine filter structure 120 may be embodied as a light-shielding breathable type structure, such as a light-shielding breathable film. And are not limited.

In this embodiment, the fine filter structure 120 is a porous and breathable structure. It will be appreciated that the porous structure of the fine filter structure 120 may be a macroporous structure that is visible to the naked eye of a user or a fine porous structure that is more difficult to see by the naked eye of a user. The fine filter structure 120 is at least permeable to gas, thereby ensuring that fine molecules of the hair care substance can be smoothly discharged out of the cavity 111 when driven by an external force.

Further, in an embodiment, the fine filtering structure 120 may be a unidirectional permeable structure, specifically, for example, a unidirectional permeable membrane or a unidirectional breathable membrane. In addition, the unidirectional permeation direction of the fine filtration structure 120 is from inside to outside, so that the hair care substances in the cavity 111 are not influenced to be outwards dispersed, and meanwhile, the impurities outside the liquid storage part 100 can be prevented from influencing the purity of the hair care substances in the cavity 111.

Further, in an embodiment, the fine filter structure 120 may be a porous ceramic. It can be understood that the porous ceramic material is prepared by taking high-quality raw materials such as corundum sand, silicon carbide, cordierite and the like as main materials through molding and special high-temperature sintering processes, has the advantages of high temperature resistance, high pressure resistance, acid resistance, alkali resistance, organic medium corrosion resistance, good biological inertia, controllable pore structure, high open porosity, long service life, good product regeneration performance and the like, and is suitable for more precisely filtering and separating hair care substances in the embodiment.

In view of the above, the fine filter structure 120 may be specifically provided as a breathable film material integrated with an auxiliary function. The thickness of the air-permeable membrane is relatively thin, is easy to obtain, contributes to reducing the burden on the overall structure and quality of the liquid storage portion 100, and is easier to connect with the main body 110.

In practical applications, when the main body 110 and the fine filtering structure 120 are made of the same material, and the fine filtering function is formed only by, for example, forming fine holes, the main body 110 and the fine filtering structure 120 can be integrally formed. In general, when the main body 110 and the fine filtering structure 120 are made of different materials, in one embodiment, the liquid storage portion 100 further includes a sealing structure, and the sealing structure is connected to the fine filtering structure 120 and the main body 110 in a sealing manner. The sealing structure can seal the junction between the main body 110 and the fine filtering structure 120, so as to avoid forming a gap between the main body and the fine filtering structure, and the hair care substance overflows through the gap.

The sealing structure may be, for example, a sealing ring, and the sealing ring may be made of rubber, metal, or the like, without limitation. Furthermore, in one embodiment, a heat seal may also be formed between body 110 and fine filter structure 120 by means of a heat press. If at least one of the main body 110 and the fine filter structure 120 is made of a hot melt material, a thermal compression process may be directly performed between the main body 110 and the fine filter structure 120; if the main body 110 and the fine filter structure 120 are not made of a hot melt material, a sealing structure can be formed between the main body 110 and the fine filter structure 120 by an additional hot melt material and a thermal compression process.
