TECHNICAL FIELD

[0001] The utility model relates to electronic atomization equipment technical field, especially relate to a liquid storage structure and atomizer. BACKGROUND

[0002] The atomizer is usually used as a cigarette substitute or a medical atomization treatment device, and a common atomizer takes an electronic cigarette as an example. The atomization device is generally a porous liquid absorbing material such as porous ceramic or porous cotton, which uses capillary action to conduct an atomization substrate (tobacco tar) from a liquid storage bin or a liquid storage medium to a heating body, and generates an aerosol for use by heating the atomization substrate with the heating body.

[0003] A common porous liquid absorbing medium includes oil storage cotton, which has a proximal liquid absorbing surface close to an oil injection port and a distal liquid guiding surface close to an atomization center. During the process of injecting oil into the oil cup, the tobacco tar first contacts the liquid absorbing surface of the oil storage cotton (porous medium) close to the oil injection port, and then spreads to the distal liquid guiding surface through the capillary action of the oil storage cotton. However, due to the small pores, the absorption efficiency of the oil storage cotton (porous medium) is slow, and the oil storage cotton (porous medium) cannot quickly reach a saturated state, resulting in that the atomizer cannot obtain enough tobacco tar and atomize in a short time, and the atomizer occurs dry burning. SUMMARY

[0004] The main purpose of the utility model is to provide a liquid storage structure and an atomizer, which can solve the problem of slow absorption of the oil storage cotton (porous medium) in the prior art.

[0005] To achieve the above-mentioned purpose, on the one hand, the application provides a liquid storage structure, which includes a body with a porous structure, the body has a proximal end and a distal end, and at least one liquid-impermeable flow guide channel extends from the proximal end to the distal end.

In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many different ways other than those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as understood by those skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments of the present application and are not intended to limit the present application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] In the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0026] The atomizer can be used in different fields, such as medical atomization, cosmetic atomization, cigarette replacement, etc., mainly using heating to atomize the substrate to generate aerosol, and the atomized substrate can be a liquid medicine, a nutrient solution or other liquid substrate with special aroma composition, etc. When the atomizer works, the atomized substrate is atomized by the atomization assembly to form aerosol. The existing atomization methods can be heating or non-heating, wherein the heating methods include resistance heating, electromagnetic heating, laser heating, infrared heating and microwave heating, etc.; the non-heating methods include ultrasonic atomization, pressure atomization, mechanical vibration atomization and compressed air atomization, etc.

[0027] As shown in Figures 1 to 5 The present application provides a liquid storage structure, which comprises a body 21 with a porous structure, the body 21 has a proximal end 200 and a distal end 201, at least one liquid-impermeable flow channel 22 extends from the proximal end 200 to the distal end 201.

[0028] Specifically, referring to Figure 2As shown, the body 21 of the liquid storage structure 20 has a surface, part of the surface has a plurality of liquid permeable holes 210 penetrating into the interior of the body 21, and part of the surface is provided with a flow guide 22 without the liquid permeable holes 210. In some embodiments, the end of the liquid storage structure 20 that is preferentially in contact with the liquid can be defined as the "proximal end 200", and the position where the liquid is finally in contact with the liquid can be defined as the "distal end 201". It can be understood that in some environments where the liquid is injected or absorbed by the liquid storage structure 20, the top of the liquid storage structure 20 is preferentially in contact with the liquid, and then the liquid gradually permeates to various positions of the liquid storage structure 20 through the liquid permeable holes 210 by the self-weight of the liquid, so the top of the liquid storage structure 20 can also be defined as the "proximal end 200", and the bottom of the liquid storage structure 20 is defined as the distal end 201. In addition, see Figure 2 As shown, the "proximal end 200" can also be the end of the liquid storage structure 20 arranged in the atomizer close to the oil injection port 11, and the position away from the oil injection port 11 is defined as the "distal end 201".

[0029] It can be understood that the "liquid impermeable" in the foregoing can mean that the liquid cannot penetrate into the interior of the body 21 from the liquid permeable holes 210 on the surface of the body 21 under the surface tension. It can also mean that the liquid cannot penetrate into the liquid permeable holes 210 on the surface of the body 21.

[0030] There are many ways to close the liquid permeable holes 210, including but not limited to melting, coating, etc. For example, when the liquid storage structure 20 is a meltable oil storage cotton, the hole of the liquid permeable hole 210 can be closed by melting on the surface of the oil storage cotton; or the liquid permeable holes 210 on the preset flow guide 22 path can be closed by coating adhesive or filling material.

[0031] The surface of the liquid storage structure 20 is provided with a plurality of flow guides 22, and the plurality of flow guides 22 can be reasonably distributed on the surface of the liquid storage structure 20. In addition, the plurality of flow guides 22 has at least one common communication, which can serve as the proximal end 200 that preferentially receives the liquid. For example Figure 3 Or Figure 4 As shown, the liquid storage structure 20 is provided with a main flow channel, and a plurality of sub-flow channels 220 extend from the main flow channel to multiple directions of the liquid storage structure 20. The main flow channel or the sub-flow channel 220 can be annularly arranged on the surface of the liquid storage structure 20. It can be understood that the communication can be defined as the proximal end 200 of the liquid storage structure 20, and when the liquid flows into the proximal end 200, the liquid can be dispersed into each flow guide 22 connected.

[0032] The liquid storage structure 20 is provided with multiple guide channels 22, of which at least some guide channels 22 are provided on the surface of the liquid storage structure 20, and some guide channels 22 extend into the interior of the liquid storage structure 20. For example, the liquid storage structure 20 is a cube with multiple guide channels 22. Some guide channels 22 extend from one side of the surface of the liquid storage structure 20 to the other side, and some guide channels 22 penetrate through the liquid storage structure 20, running from one side of the liquid storage structure 20 to the other side.

[0033] In some embodiments, at least a portion of the flow channels 22 extend to the distal end 201 on both sides of the proximal end 200 of the liquid storage structure 20, and are either interconnected or disconnected at the distal end 201. When liquid permeates from the top to the bottom of the liquid storage structure 20 by its own weight, even if the multiple flow channels 22 are not interconnected near the bottom of the liquid storage structure 20, it will not significantly affect the liquid absorption of the liquid storage structure 20. See also Figure 4 As shown, some of the guide channels 22 extend to the bottom on both sides of the top of the liquid storage structure 20 and form a connection near the bottom.

[0034] See Figure 5 As shown, a guide hole 221 is provided along the extension path of the guide channel 22, extending into the interior of the liquid storage structure 20. When the liquid flows along the guide channel 22, some of the liquid can penetrate approximately vertically into the bottom of the liquid storage structure 20 through the guide hole 221, thereby accelerating the absorption efficiency of the liquid inside the liquid storage structure 20.

[0035] The flow guide hole 221 can connect the proximal end 200 of the liquid storage structure 20 to the distal end 201 of the liquid storage structure 20, and the flow guide hole 221 can also act as a capillary, guiding the liquid that is preferentially close to the distal end 201 of the liquid storage structure 20 to the proximal end 200 through capillary action. The flow guide hole 221 can be axially extended or curved.

[0036] On the other hand, the aforementioned liquid storage structure 20 can be used in an atomizer. This application provides an atomizer having an oil cup 10 and the aforementioned liquid storage structure 20. The oil cup 10 has a liquid storage chamber 12 for receiving liquid. The liquid storage structure 20 can be installed in the liquid storage chamber 12 and absorb liquid atomizing matrix (e-liquid) in the liquid storage chamber 12.

[0037] See Figure 1 As shown, the oil cup 10 has an oil inlet 11 through which the atomizing matrix can be injected into the liquid storage chamber 12. The side of the liquid storage structure 20 closest to the oil inlet 11 can be defined as the proximal end 200. The oil inlet 11 is sealed by a sealing element 13.

[0038] In some embodiments, the atomizer further has an atomizing assembly arranged in the oil cup 10, the atomizing assembly and the inner wall of the oil cup 10 form a liquid storage cavity 12 for storing liquid, the outer wall of the atomizing assembly is attached to the liquid storage structure 20, and the atomizing assembly comprises an atomizing chamber for atomizing the liquid, the atomizing chamber is communicated with the liquid storage cavity 12 through a liquid inlet hole, and part of the flow guide channel 22 on the liquid storage structure 20 can be communicated with or close to the liquid inlet hole. When the liquid is injected into the liquid storage cavity 12, at least part of the liquid can preferentially approach the liquid inlet hole along the flow guide channel 22 and enter the atomizing chamber through the liquid inlet hole.

[0039] The above only describes some or preferred embodiments of the present application, neither the text nor the drawings can limit the scope of protection of the present application, any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the scope of protection of the present application.
