First embodiment

Fig. 1 is a schematic structural diagram of a liquid storage device according to a first embodiment of the invention. Referring to fig. 1, a liquid storage device according to the present embodiment for absorbing, storing and releasing liquid includes a porous body made of bonded fibers, including a low-density portion 20, a high-density portion 22, and a descending capillary portion 21 disposed between the low-density portion 20 and the high-density portion 22, an ascending capillary pressure of the descending capillary portion 21 being gradually decreased from the high-density portion 22 to the low-density portion 20; the high-density portion 22 has a cross-sectional area of 10 to 80% of a cross-sectional area of the low-density portion 20, and the low-density portion 20 has a density of 10 to 80% of a density of the high-density portion 22, wherein the liquid storage device further includes a preheating part 31 for preheating the liquid stored in the porous body. The liquid emitting device using the liquid storage device of the present invention, such as electric mosquito repellent, air freshener, electronic cigarette, etc., uses the high-density part 22 or the end face of the high-density part 22 as the liquid emitting part. Thus, when the liquid is discharged, the liquid is concentrated from the low-density portion 20 to the high-density portion 22, so that the liquid emitting apparatus using the porous body can emit the effective components of the liquid more uniformly, reduce the residual amount, and reduce pollution and resource waste. Further, the liquid storage apparatus 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 the preheating, thereby enhancing the effect of atomization.

For example, when a liquid having a high viscosity such as a fine oil is stored in the liquid storage device, the preheating unit 31 may heat the liquid in the porous body to lower the viscosity and improve the fluidity. Therefore, the liquid emission device adopting the liquid storage device can control the enrichment of essential oil through the descending of the ascending capillary pressure of the porous body, effectively improve the uniformity of atomization and volatilization and greatly reduce the residual quantity in the porous body. Since liquids with high viscosity such as essential oils are generally expensive, the residual amount in the porous body can be greatly reduced and the waste of resources can be effectively reduced by using the liquid storage device according to the present invention. Further, since the liquid stored therein can be sufficiently discharged by using the liquid storage device according to the present invention, the porous body can be miniaturized.

According to the liquid storage device, the cross sectional area of the connection between the descending capillary part 21 and the high-density part 22 is 10% -80%, preferably 25% -65% of the cross sectional area of the connection between the descending capillary part 21 and the low-density part 20. The density of the low-density portion 20 is 10% to 80%, preferably 25% to 65%, of the density of the high-density portion 22.

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 difference in density between the low-density portion 20 and the high-density portion 22 is sufficiently large, and the effect of enriching the liquid from the low-density portion 20 to the high-density portion 22 is sufficiently good; still further increasing the density difference between the low-density portion 20 and the high-density portion 22, i.e., when the ratio of the density of the low-density portion 20 to the density of the high-density portion 22 is less than 10%, results in an increase in production cost and difficulty in manufacturing. When the ratio of the density of the low-density portion 20 to the density of the high-density portion 22 is greater than 80%, the difference in density between the low-density portion 20 and the high-density portion 22 is excessively small, the effect of enriching the liquid from the low-density portion 20 to the high-density portion 22 is insignificant, and the liquid stored in the porous body is difficult to be sufficiently released, resulting in excessive liquid remaining in the porous body, and excessive residual amount, which results in waste of resources.

The high-density portion 22 has a density of 0.08 to 0.55g/cc, preferably 0.15 to 0.45 g/cc; the low-density portion 20 has a density of 0.03 to 0.35g/cc, preferably 0.05 to 0.25 g/cc; g/cc is grams per cubic centimeter. When the density of the low-density portion 20 is less than 0.03g/cc, the low-density portion 20 is difficult to mold and difficult to manufacture. When the density of the low-density portion 20 is more than 0.35g/cc, the liquid-absorbing ability of the low-density portion 20 is too strong, and the liquid is released, it becomes difficult for the liquid to be enriched from the low-density portion 20 to the high-density portion 22, so that the residual amount of the liquid in the porous body becomes too large, resulting in a waste of resources.

When the density of the high-density portion 22 is less than 0.08g/cc, the liquid-absorbing capacity of the high-density portion 22 is too weak, and when the liquid is discharged, the liquid is difficult to be enriched from the low-density portion 20 to the high-density portion 22. When the density of the high-density portion 22 is more than 0.55g/cc, the production is difficult.

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

When the ratio of the rising capillary pressure of the low-density portion 20 to the rising capillary pressure of the high-density portion 22 exceeds 80%, a large amount of liquid is absorbed into the descending capillary portion 21 and the low-density portion 20, and the liquid stored in the porous body is difficult to be sufficiently released, so that the liquid remaining in the porous body is excessive, and the remaining amount is too large, resulting in waste of resources. When the ratio of the rising capillary pressure of the low-density portion 20 to the rising capillary pressure of the high-density portion 22 is less than 10%, the liquid-absorbing ability of the low-density portion 20 is too small to facilitate the absorption and storage of liquid in the porous body.

The ratio of the capillary pressure increase of the low-density portion 20 to the capillary pressure increase of the high-density portion 22 in the present embodiment is preferably in the range of 25% to 65%.

The preheating part 31 in the present embodiment may be configured to accommodate and preheat the porous body, i.e., the porous body is entirely or at least the high-density portion 22 is installed in the preheating part 31. The shaped pre-heating element 31 allows the porous body to be easily shaped to form the tapered capillary portion 21 and the high density portion 22 in the appropriate shape. I.e. the high-density portion 22 and the tapered capillary portion 21, may be formed by radially pressing the porous material from the outside to the inside by the preheating member 31.

When the low-density part 20 or the high-density part 22 and the tapered capillary part 21 are in a split structure, the preheating part 31 facilitates close contact between the materials, so that liquid can smoothly circulate between the materials.

In this embodiment, the high-density portion 22 and the tapered capillary portion 21 are shaped into a desired shape when the porous material is assembled with the preheating part 31. In this case, a porous material having a uniform density before installation is selected, and the porous material is molded into a porous body having a desired shape by the shape of the preheating member 31 at the time of installation, that is, the porous body is formed by radially pressing an integrated porous material having a uniform density from the outside to the inside by the preheating member 31 as shown in fig. 1. The scheme is convenient to produce and manufacture and low in cost.

The warming member 31 may be pre-assembled with the porous body and then mounted to the liquid dispensing device. Alternatively, the preheating member 31 may be provided on the liquid dispensing apparatus, and the porous body may be assembled with the preheating member 31. The preheating part 31 is preferably provided on the liquid dispersion device in view of easy replacement of the porous body for storing the liquid.

The liquid storage device may further include a porous body accommodating chamber 5, the porous body accommodating chamber 5 may be used to accommodate a porous body, and a sealing cover (not shown) may be added on the top of the porous body accommodating chamber 5 to seal, transport and store the porous body, so as to ensure that the volatilization amount of the porous body storing liquid before use is reduced as much as possible.

As shown in the sectional view a-a in fig. 1, the inner diameter of the porous-body accommodating chamber 5 in the present embodiment is slightly larger than the maximum diameter of the porous body, and pores 51 are formed to facilitate the opening of the air passage between the porous body and the outside after assembly, thereby ensuring that the liquid stored in the porous body can be enriched to the high-density portion 22.

As shown in the cross-sectional view B-B in fig. 1, the inner wall of the preheating part 31 in this embodiment is provided with at least one ventilation groove 52, and preferably 2 to 6 grooves 52, and in this embodiment 3 grooves 52 are provided, and the grooves 52 are communicated with the aperture 51. When the preheating part 31 can be assembled with the porous body, the groove 52 can ensure that the air path of the porous body is open to the outside. Of course, one or more vent holes (not shown) may be provided in the preheating member 31 to communicate with the pores 51, thereby ensuring that the porous body is open to the outside air passage.

The porous body is made by bonding filaments or staple fibers, and the bonding method may be bonding means such as an adhesive or thermal bonding.

The fiber fineness of the prepared porous body is between 0.2 and 30 deniers. Denier is the mass in grams of 9000m long fibers at a nominal moisture regain. The fiber size of the porous bodies made according to the present invention is preferably 1 denier to 15 denier, most preferably 2 denier to 6 denier.

The fiber component for preparing the porous body can be single-component fiber, such as PE, PP, PET, PBT, PTT, nylon 6, nylon 66, polylactic acid and the like, or bi-component fiber, such as PE/PP, PE/PET, PP/PET, EVA/PET, PBT/PET, nylon 6/nylon 66 and the like, or a mixture of the single-component fiber and the bi-component fiber.

The porous body is provided with an inner hole at the radial center. The porous body in the present invention is a porous material made of bonded fibers, but may be made of sponge, porous plastic, felt, or the like. Through certain process control, the axial strength of the bonded fiber porous body can be higher than the radial strength, so that the radial compression and the axial assembly are facilitated. The inner hole can be formed while the fibers are bonded, so that the insertion of an auxiliary component is facilitated.

The porous body comprises a low-density part 20, a descending capillary part 21 and a high-density part 22, and is integrated or split. The integrated structure is convenient to assemble and low in cost, and the split structure has more choices in material selection of each part.

When the low-density part 20 and the tapered capillary part 21 are integrated, the rising capillary pressure of the low-density part 20 and the portion where the tapered capillary part 21 borders is the same as the rising capillary pressure of the low-density part 20. When the high-density portion 22 and the tapered capillary portion 21 are integrated, the rising capillary pressure at the interface between the high-density portion 22 and the tapered capillary portion 21 is the same as the rising capillary pressure of the high-density portion 22. When the low-density portion 20, the descending capillary portion 21 and the high-density portion 22 are separated, the ascending capillary pressure at the junction of the low-density portion 20 and the descending capillary portion 21 and the ascending capillary pressure of the low-density portion 20 may be the same or different, and the ascending capillary pressure at the junction of the high-density portion 22 and the descending capillary portion 21 and the ascending capillary pressure of the high-density portion 22 may be the same or different, according to the selection of materials.

The invention can adopt the integral porous material to radially compress to form the high-density part 22 and the descending capillary part 21, thereby not only meeting the requirement on the ascending capillary pressure, but also reducing the parts and being convenient for manufacturing. The ascending capillary pressure of the tapered capillary portion 21 is tapered from the high-density portion 22 toward the low-density portion 20, and in this case, the performance of the portion of the tapered capillary portion 21 near the high-density portion 22 is close to the high-density portion 22, and the performance of the portion thereof near the low-density portion 20 is close to the low-density portion 20. This structure ensures both the reliability of liquid storage and the reliability of liquid enrichment into the high-density portion 22 when the liquid is dispensed.

The radial center of the low-density portion 20, the tapered capillary portion 21, or the high-density portion 22 may be formed with a through hole to facilitate insertion of the auxiliary member during assembly. When the high-density portion 22, the tapered capillary portion 21, or the low-density portion 20 has a through hole, the above cross-sectional area does not include the cross-sectional area of the hole.

Compared with the prior art, the liquid emission device using the liquid storage device of the embodiment has the advantages of less residual liquid amount, simple structure and easiness in manufacturing.

Second embodiment

Fig. 2 is a schematic structural diagram of a liquid storage device according to a second embodiment of the invention. The structure of this embodiment is similar to that of the first embodiment, and the same parts as those of the first embodiment are not described again in the description of this embodiment.

Referring to fig. 2, a liquid storage device according to the present embodiment for absorbing, storing and releasing liquid includes a porous body made of bonded fibers, including a low-density portion 20, a high-density portion 22, and a descending capillary portion 21 disposed between the low-density portion 20 and the high-density portion 22, an ascending capillary pressure of the descending capillary portion 21 being gradually decreased from the high-density portion 22 to the low-density portion 20; the high-density portion 22 has a cross-sectional area of 10 to 80% of a cross-sectional area of the low-density portion 20, and the low-density portion 20 has a density of 10 to 80% of a density of the high-density portion 22, wherein the liquid storage device further includes a preheating part 32 for preheating the liquid stored in the porous body.

The porous body in this embodiment is formed by radially pressing a unitary porous material having a uniform density from the inside to the outside by the preheating member 32.

The preheating part 32 may be a preheating wick inserted into the porous body. The preheating core includes a large diameter portion, a decreasing diameter portion, and a small diameter portion corresponding to the high density portion 22, the decreasing capillary portion 21, and the low density portion 20, respectively. The small diameter portion extends from the joint end surface of the tapered capillary portion 21 and the low density portion 20 to the other end surface, and the length of the small diameter portion may be zero or may extend all the way to the other end surface of the low density portion 20.

The pre-heat wick may be pre-assembled with the porous body and then mounted to the liquid dispensing device. Alternatively, the pre-heating core may be disposed on the liquid dispensing device and the porous body may be assembled with the pre-heating core. In view of the ease of replacement of the porous body for storing the liquid, it is preferable that the preheating wick be provided on the liquid dispensing device.

To facilitate the insertion of the preheating core into the porous body, the radial center of the porous body may be provided with an inner hole. The small diameter portion of the preheating core may be formed in a conical shape.

Through the technical scheme of this embodiment, it is convenient to produce, low cost. The preheating part 32 can not only mold the porous material into the porous body with the required shape, but also preheat the porous body from the inside to the outside, especially the preheating part 32 is arranged to extend to the other end face of the low density part 20, the preheating part 32 can preheat the high density part 22, the tapered capillary part 21 and the low density part 20 at the same time, and the liquid in the porous body can be effectively heated, so that the viscosity is reduced and the fluidity is improved.

Meanwhile, the preheating part 32 is set in a diameter-variable structure, that is, the diameter gradually increases from the low-density part 20 to the high-density part 22, so that the preheating effect is gradually enhanced from the low-density part 20 to the high-density part 22, which is more favorable for the enrichment of liquid to the high-density part 22, and thus the liquid emitting device adopting the porous body can more uniformly emit the effective components of the liquid, reduce the residual quantity, and reduce pollution and resource waste.

The liquid storage device may further include a porous body accommodating chamber 5, the porous body accommodating chamber 5 may be used to accommodate a porous body, and a sealing cover (not shown) may be added on the top of the porous body accommodating chamber 5 to seal, transport and store the porous body, so as to ensure that the volatilization amount of the porous body storing liquid before use is reduced as much as possible.

As shown in the sectional view of C-C in fig. 2, at least one ventilation groove 52 is provided on the inner wall of the porous-body accommodating chamber 5 in the present embodiment, and preferably 2 to 6 grooves 52, in the present embodiment 3 grooves 52 are provided. The grooves 52 ensure that the porous body is in open communication with the outside when the preheating part 32 is assembled with the porous body. Of course, the inner diameter of the porous-body accommodating chamber 5 may be set slightly larger than the maximum diameter of the porous body, so that pores (not shown) are formed between the porous-body accommodating chamber and the porous body, thereby ensuring that the air passage of the porous body to the outside is open.

When the liquid emitting device of the liquid storage device, such as electric mosquito repellent, air freshener, electronic cigarette and other products, is adopted, the preheating component 32 can heat the liquid in the porous body, so that the viscosity of the liquid is reduced, the fluidity of the liquid is improved, and the liquid is enriched from the low-density part 20 to the high-density part 22 when the liquid is released, so that the liquid emitting device adopting the porous body can more uniformly emit the effective components of the liquid, reduce the residual quantity, and reduce pollution and resource waste.

The fiber component for preparing the porous body can be single-component fiber, such as PE, PP, PET, PBT, PTT, nylon 6, nylon 66, polylactic acid and the like, or double-component fiber, such as PE/PP, PE/PET, PP/PET, EVA/PET, PBT/PET, nylon 6/nylon 66 and the like, or a mixture of the single-component fiber and the double-component fiber. The fiber fineness of the porous body is between 0.2 and 30 deniers, and the porous body can be made of fibers with single fineness or fibers with multiple deniers.

The liquid storage device in this embodiment may further include a porous body accommodating chamber 5, the porous body accommodating chamber 5 may be used to accommodate a porous body, and a sealing cover (not shown) may be added on the top of the porous body accommodating chamber 5 to seal, transport and store the porous body, so as to ensure that the volatilization amount of the porous body storing liquid before use is reduced as much as possible.

The inner diameter of the porous-body accommodating chamber 5 is set slightly larger than the maximum diameter of the porous body, so that pores 51 are formed between the porous-body accommodating chamber and the porous body, thereby ensuring an open air passage of the porous body to the outside.

By applying the first liquid emitting device of the liquid storage device of the invention, the liquid emitting promoting part 4 is close to or contacts the high-density part 22, so that the liquid essence enriched in the high-density part 22 can be emitted conveniently when air circulates.

Since the rising capillary pressure of the high-density portion 22 is the largest, the liquid in the porous body is constantly enriched to the high-density portion when the liquid in the high-density portion 22 is consumed. The preheating unit 32 can heat the liquid in the porous body to lower the viscosity and improve the fluidity. Compared with a liquid carrier with uniform density without a preheating component, the porous body of the invention can make the dispersion amount of the liquid more uniform and more completely release the liquid stored in the porous body.

The structure of this embodiment is similar to that of the third embodiment, and the parts that are the same as those of the third embodiment are not described again in the description of this embodiment.

As shown in FIG. 4, the liquid dispensing device comprises a liquid dispensing-promoting portion 4 and the liquid storage device described above, and the liquid dispensing-promoting portion 4 is adjacent to or in contact with the porous body high-density portion 22.

The liquid storage device in the embodiment is used for absorbing, storing and releasing liquid, and comprises a porous body, wherein the porous body is made of bonded fibers and comprises a low-density part 20, a high-density part 22 and a descending capillary part 21 arranged between the low-density part 20 and the high-density part 22, and the ascending capillary pressure of the descending capillary part 21 is gradually reduced from the high-density part 22 to the low-density part 20; the high-density portion 22 has a cross-sectional area of 10 to 80% of a cross-sectional area of the low-density portion 20, and the low-density portion 20 has a density of 10 to 80% of a density of the high-density portion 22, wherein the liquid storage device further includes a preheating part 32 for preheating the liquid stored in the porous body. The liquid emanation device further comprises an integrated stand 6 for mounting the liquid emanation initiation means 4 and/or the pre-heating means 32.

As shown in fig. 4, the porous body in this embodiment is formed by simultaneously radially pressing the integrated porous material having a uniform density from the outside to the inside and radially pressing the integrated porous material from the inside to the outside through the integrated jig 6 and the preheating part 32. The preheating part 32 may be a preheating wick inserted into the porous body. By the combined action of the integration shelf 6 and the preheating part 32, the low-density portion 20, the high-density portion 22, and the tapered capillary portion 21 provided between the low-density portion 20 and the high-density portion 22 can be more reliably formed.

Fifth embodiment

FIG. 5 is a schematic view of a third fluid dispensing device incorporating a reservoir of the present invention. The present embodiment has a similar structure to the fourth embodiment, and the same parts as the fourth embodiment are not described again in the description of the present embodiment.

As shown in FIG. 5, the liquid dispensing device comprises a liquid dispensing-promoting portion 4 and the liquid storage device described above, and the liquid dispensing-promoting portion 4 is adjacent to or in contact with the porous body high-density portion 22.

The liquid storage device in the embodiment is used for absorbing, storing and releasing liquid, and comprises a porous body, wherein the porous body is made of bonded fibers and comprises a low-density part 20, a high-density part 22 and a descending capillary part 21 arranged between the low-density part 20 and the high-density part 22, and the ascending capillary pressure of the descending capillary part 21 is gradually reduced from the high-density part 22 to the low-density part 20; the cross-sectional area of the high-density portion 22 is 10-80% of the cross-sectional area of the low-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 includes a preheating part 31 and a preheating part 32 for preheating the liquid stored in the porous body.

The preheating component 31 may serve as an integrated rack for assembling the liquid emanation-activating portion 4 and/or the preheating component 32. The preheating part 32 may be a preheating wick inserted into the porous body.

As shown in fig. 5, the porous body in this embodiment is formed by simultaneously radially pressing the uniform-density integrated porous material from the outside to the inside and radially pressing the same from the inside to the outside by the preheating part 31 and the preheating part 32.

By the cooperation of the preheating part 31 and the preheating part 32, the low-density portion 20, the high-density portion 22, and the tapered capillary portion 21 disposed between the low-density portion 20 and the high-density portion 22 can be more reliably formed. Meanwhile, the preheating part 32 preheats the porous body from the inside to the outside while the preheating part 31 preheats the porous body from the outside to fully heat the liquid in the porous body, so that the viscosity of the liquid is reduced and the fluidity of the liquid is improved.

In summary, the porous body and the liquid emission device using the porous body of the invention gasify or atomize liquid, and the preheating component for preheating the liquid in the porous body is arranged, so that the liquid emission is more stable, the residual quantity is lower, and the porous body is small and exquisite in structure and convenient to carry and use; if a coloring matter is added to the liquid, the state of use of the liquid in the porous body can also be judged from the change in color of each part of the porous body.
