first embodiment

FIG. 1 is a schematic structural diagram of a liquid storage device according to a first embodiment of the present invention. Referring to FIG. 1 , a liquid storage device according to the present embodiment is used for absorbing, storing and releasing liquid. The liquid storage device includes a porous body, and the porous body is made of fiber bonding and includes a low-density part 20 and a high-density part 22 and the decreasing capillary portion 21 disposed between the low-density portion 20 and the high-density portion 22, the ascending capillary pressure of the decreasing capillary portion 21 decreases from the high-density portion 22 to the low-density portion 20; the cross-sectional area of the high-density portion 22 is low 10-80% of the cross-sectional area of the density portion 20, and the density of the low-density portion 20 is 10-80% of the density of the high-density portion 22, wherein the liquid storage device further comprises a liquid storage device for preheating the liquid stored in the porous body. Preheat part 31 . The liquid emitting device using the liquid storage device of the present invention, such as electric mosquito coils, air fresheners, electronic cigarettes and other products, uses the high-density part 22 or the end face of the high-density part 22 as the liquid emitting part. In this way, when the liquid is released, the liquid is enriched from the low-density part 20 to the high-density part 22, so that the liquid distribution device using this porous body can more uniformly distribute the active components of the liquid, reduce the residual amount, and reduce pollution and resource waste. In addition, the liquid storage device further includes a preheating part 31 for preheating the liquid stored in the porous body, and the fluidity of the liquid stored in the porous body can be improved by preheating, thereby improving the effect of atomization.

For example, when a liquid with high viscosity such as essential oil is stored in the liquid storage device, the preheating part 31 can heat the liquid in the porous body to reduce the viscosity and improve the fluidity. Therefore, the liquid emitting device using this liquid storage device can control the enrichment of essential oils by decreasing the ascending capillary pressure of the porous body, effectively improve the uniformity of atomization and volatilization, and greatly reduce the residual amount in the porous body. Since high-viscosity liquids such as essential oils are usually expensive, using the liquid storage device according to the present invention can greatly reduce the residual amount in the porous body, and can effectively reduce the waste of resources. In addition, since the liquid storage device according to the present invention can sufficiently release the liquid stored therein, the porous body can be miniaturized.

In the liquid storage device of the present invention, the cross-sectional area of the decreasing capillary portion 21 bordering the high-density portion 22 is 10%-80% of the cross-sectional area bordering the decreasing capillary portion 21 and the low-density portion 20, preferably 25%-65% . In addition, the density of the low density portion 20 is 10% to 80% of the density of the high density portion 22, preferably 25% to 65%.

When the ratio of the density of the low-density portion 20 to the density of the high-density portion 22 is equal to 10%, the density difference between the low-density portion 20 and the high-density portion 22 is sufficiently large that the liquid flows from the low-density portion 20 to the high-density portion 22 The enrichment effect is good enough; further increasing the density difference between the low-density part 20 and the high-density part 22, that is, when the ratio of the density of the low-density part 20 to the density of the high-density part 22 is less than 10%, will lead to Production costs increase and manufacturing is difficult. When the ratio of the density of the low-density part 20 to the density of the high-density part 22 is greater than 80%, the density difference between the low-density part 20 and the high-density part 22 is too small, and the liquid flows from the low-density part 20 to the high-density part 22 The enrichment effect is not obvious, and the liquid stored in the porous body is difficult to be fully released, resulting in too much liquid remaining in the porous body, and the residual amount is too large, resulting in waste of resources.

The density of the high-density portion 22 is between 0.08-0.55g/cc, preferably 0.15-0.45g/cc; the density of the low-density portion 20 is between 0.03-0.35g/cc, preferably 0.05-0.25g/cc; g/cc is grams per cubic centimeter. When the density of the low-density portion 20 is less than 0.03 g/cc, it is difficult to mold the low-density portion 20 and manufacture is difficult. When the density of the low-density portion 20 is greater than 0.35 g/cc, the liquid-absorbing ability of the low-density portion 20 is too strong, and when the liquid is released, it is difficult for the liquid to accumulate from the low-density portion 20 to the high-density portion 22, so that the liquid in the porous body remains. Excessive quantities lead to waste of resources.

When the density of the high-density portion 22 is less than 0.08 g/cc, the liquid-absorbing ability of the high-density portion 22 is too weak, and when the liquid is released, it is difficult for the liquid to accumulate from the low-density portion 20 to the high-density portion 22 . When the density of the high-density portion 22 is greater than 0.55 g/cc, it is difficult to manufacture.

The rising capillary pressure of the low density part 20 is 10%-80% of the rising capillary pressure of the high density part 22, for example, the rising capillary pressure of the low density part 20 is 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%. When the ratio of the rising capillary pressure of the low-density part 20 to the rising capillary pressure of the high-density part 22 is larger, it is more difficult for the liquid to accumulate from the low-density part 20 to the high-density part 22 . When the ratio of the rising capillary pressure of the low-density part 20 to the rising capillary pressure of the high-density part 22 is smaller, the liquid is more likely to be enriched from the low-density part 20 to the high-density part 22 .

When the ratio of the ascending capillary pressure of the low-density part 20 to the ascending capillary pressure of the high-density part 22 exceeds 80%, a large amount of liquid will be absorbed into the descending capillary part 21 and the low-density part 20, and it is difficult for the liquid stored in the porous body to be sufficient. Released, resulting in too much liquid remaining in the porous body, and the residual amount is too large, resulting in waste of resources. When the ratio of the rising capillary pressure of the low density part 20 to the rising capillary pressure of the high density part 22 is lower than 10%, the liquid absorption capacity of the low density part 20 is too small, which is not conducive to the absorption and storage of liquid in the porous body.

The ratio of the rising capillary pressure of the low-density portion 20 to the rising capillary pressure of the high-density portion 22 in the present embodiment preferably ranges from 25% to 65%.

The preheating part 31 in this embodiment can be configured to accommodate and preheat the porous body, that is, all or at least the high-density part 22 of the porous body is installed in the preheating part 31 . The preheating part 31 made into a certain shape can easily shape the porous body, so as to form the decreasing capillary part 21 and the high density part 22 in proper shape. That is, the high-density portion 22 and the decreasing capillary portion 21 may be formed by radially extruding the porous material from the outer to the inner side of the preheating member 31 .

When the low-density part 20 or the high-density part 22 and the decreasing capillary part 21 are separate structures, the preheating part 31 helps the materials to be in close contact, so that the liquid flows smoothly between the parts.

In this embodiment, when the porous material is assembled with the preheating part 31, the high-density portion 22 and the decreasing capillary portion 21 are molded into a desired shape. In this case, the porous material with the same density before installation is selected, and the shape of the preheating part 31 is used to shape the porous material into a porous body of the required shape during installation, that is, as shown in FIG. A one-piece porous material of uniform density is formed by radial extrusion from the outside to the inside. The solution is convenient to manufacture and has low cost.

The preheating part 31 can be pre-assembled with the porous body and then mounted on the liquid dispensing device. Alternatively, the preheating part 31 may be arranged on the liquid distribution device, and then the porous body and the preheating part 31 may be assembled. Considering that the porous body for storing the liquid is easy to replace, it is preferable to provide the preheating part 31 on the liquid emitting device.

The liquid storage device can also include a porous body accommodating chamber 5, which can be used to accommodate the porous body, and a sealing cover (not shown) can be installed on the top of the porous body accommodating chamber 5 to seal, transport and store the porous body. body, to ensure that the volatilization of the porous body storing the liquid is minimized before use.

As shown in the cross-sectional view of A-A in FIG. 1 , the inner diameter of the porous body accommodating chamber 5 in this embodiment is slightly larger than the maximum diameter of the porous body to form pores 51, so as to facilitate the smooth air passage between the porous body and the outside after assembly, thereby It is ensured that the liquid stored in the porous body can be enriched to the high density part 22 .

As shown in the cross-sectional view of B-B in FIG. 1 , the inner wall of the preheating component 31 in this embodiment is provided with at least one ventilation groove 52 . A groove 52 communicates with the hole 51 . When the preheating part 31 can be assembled with the porous body, the groove 52 can ensure that the air passage between the porous body and the outside is unobstructed. Of course, one or more ventilation holes (not shown) may also be provided in the preheating component 31 to communicate with the pores 51, so as to ensure that the air passage between the porous body and the outside is unobstructed.

The porous body is made by bonding filaments or short fibers, and the bonding method can be bonding methods such as adhesives or thermal bonding.

The fineness of the fibers made into the porous body is between 0.2 denier and 30 denier. Denier refers to the mass grams of 9000m long fibers at a given moisture regain. The fineness of the fibers made into the porous body of the present invention is preferably 1 denier to 15 denier, and most preferably 2 denier to 6 denier.

The fiber components that make the porous body can be monocomponent fibers, such as PE, PP, PET, PBT, PTT, nylon 6, nylon 66, polylactic acid, etc., or bicomponent fibers, such as PE/PP, PE/ PET, PP/PET, EVA/PET, PBT/PET, Nylon/PET, Nylon 6/Nylon 66, etc., or a mixture of monocomponent fibers and bicomponent fibers.

The radial center of the porous body is provided with an inner hole. In the present invention, the porous body is a porous material made by bonding fibers, but it can also be made of sponge, porous plastic or felt. Through certain process control, the axial strength of the bonded fiber porous body can be higher than the radial strength, which is convenient for both radial compression and axial assembly. It is also possible to form an inner hole at the same time as the fiber is bonded to facilitate the insertion of auxiliary components.

The porous body includes a low-density part 20 , a decreasing capillary part 21 and a high-density part 22 , which are integrated or separated. The one-piece structure is easy to assemble and the cost is low, and the split-type structure has more choices in the material selection of each part.

When the low density portion 20 and the decreasing capillary portion 21 are integrated, the rising capillary pressure at the border of the low density portion 20 and the decreasing capillary portion 21 is the same as the rising capillary pressure of the low density portion 20 . When the high density portion 22 and the decreasing capillary portion 21 are integrated, the rising capillary pressure at the border of the high density portion 22 and the decreasing capillary portion 21 is the same as the rising capillary pressure of the high density portion 22 . When the low-density part 20 , the decreasing capillary part 21 and the high-density part 22 are separated, according to the choice of materials, the rising capillary pressure at the border of the low-density part 20 and the decreasing capillary part 21 and the rising capillary pressure of the low-density part 20 The rising capillary pressure where the high density portion 22 borders the decreasing capillary portion 21 and the rising capillary pressure at the high density portion 22 may be the same or different, which may be the same or different.

In the present invention, the high-density part 22 and the decreasing capillary part 21 can be formed by radial compression of an integrated porous material, which not only meets the requirements for the rising capillary pressure, but also reduces the number of parts and is convenient for manufacture. The ascending capillary pressure of the decreasing capillary portion 21 decreases from the high density portion 22 to the low density portion 20. In this case, the performance of the portion of the decreasing capillary portion 21 close to the high density portion 22 is close to the high density portion 22, while it is close to the low density portion. The performance of the portion 20 is close to that of the low density portion 20 . This structure can not only ensure the reliability of liquid storage, but also ensure the reliability of liquid accumulation in the high-density portion 22 when the liquid is distributed.

A through hole may be formed in the radial center of the low-density portion 20 , the decreasing capillary portion 21 , or the high-density portion 22 to facilitate the insertion of auxiliary components during assembly. When the high-density portion 22 , the decreasing capillary portion 21 or the low-density portion 20 has through holes, the above-mentioned cross-sectional area does not include the cross-sectional area of the hole.

Compared with the prior art, the liquid emitting device applying the liquid storage device of this embodiment has less residual liquid, simple structure and easy manufacture.
