Description

Technical Field

[0001] This utility model relates to the field of electronic atomization equipment technology, and in particular to an atomizing fluid channel and an atomizer. Background Technology

[0002] Atomizers are commonly used as cigarette alternatives or medical nebulization therapy devices. A common example is the electronic cigarette, which is an electronic device used to generate an aerosol from an atomizing matrix for the user to inhale. The atomizing matrix can be liquid (e.g., e-liquid) or solid or gel (e.g., tobacco paste).

[0003] Existing e-cigarettes typically use multiple containers to store e-liquid, thereby extending the e-cigarette's lifespan. At least one container supplying e-liquid to the atomizer coil contains a liquid-guiding element that absorbs e-liquid from other connected containers. When multiple containers are connected, the liquid flow between them relies entirely on the liquid-guiding element. Initially, during the first period of use, e-liquid is released into the atomizer coil too quickly, and the heating structure cannot atomize it promptly, leading to e-liquid overflow and negatively impacting the user experience. Utility Model Content

[0004] The main purpose of this invention is to propose an atomizing fluid channel that can solve the problem of excessively fast liquid transfer efficiency between multiple liquid storage containers in the existing atomizer technology.

[0005] To achieve the above objectives, this application provides an atomizing fluid channel, comprising:

[0006] A metal tube, one end of which is open and the other end is closed, and a liquid outlet hole is provided on the side wall of the metal tube, which communicates with the open end to allow fluid to pass through.

[0007] Porous ceramic is sintered inside the metal tube.

[0008] In some embodiments, the porous ceramic is at least partially exposed at the open end.

[0009] In some embodiments, the area between the end face of the porous ceramic and the end face of the open end is a clearance zone.

[0010] In some embodiments, the cross-section of the liquid outlet includes, but is not limited to, circular, Y-shaped, cross-shaped, elongated, star-shaped, or rhomboid shapes.

[0011] In some embodiments, the porous ceramic is at least partially exposed outside the metal tube through the liquid outlet hole.

[0012] In some embodiments, at least one flow channel is defined between the porous ceramic and the inner wall of the metal tube, and the flow channel communicates with the liquid outlet.

[0013] On the other hand, this application also provides an atomizer, which includes a housing, wherein a liquid storage chamber and an atomizing fluid channel as described in any of the foregoing embodiments are disposed within the housing, wherein the atomizing fluid channel is at least partially disposed within the liquid storage chamber.

[0014] In some embodiments, a liquid storage cotton is provided inside the liquid storage chamber, and the atomizing fluid channel is at least partially surrounded by the liquid storage cotton.

[0015] In some embodiments, the atomizer further includes a closure element detachably connected to the housing, the closure element being used to close the opening end.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects: during the process of replenishing the atomizing matrix in the atomizer, the porous ceramic inside the metal tube can slow down the flow rate or velocity of the atomizing matrix between containers, making it less likely for the atomizing matrix to overflow, and the air inside the container can be easily discharged in time through the fluid channel.

[0028] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this 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 commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] This application provides an atomizing fluid channel, comprising a metal tube and a porous ceramic. For example... Figures 1 to 6 As shown, one end of the metal tube 11 is an open end and the other end is a closed end. The side wall of the metal tube 11 is provided with a liquid outlet hole 110 that communicates with the open end to allow fluid to pass through. The porous ceramic 12 is sintered inside the metal tube 11.

[0031] Specifically, the metal tube 11 is hollow inside, with at least one end having an opening communicating with the outside. A liquid outlet hole 110 is provided on the wall of the metal tube 11, guiding liquid into the metal tube 11. The fluid can be directed to a predetermined destination through the liquid outlet hole 110. For example... Figure 1As shown, the metal tube 11 is closed at one end and open at the other end. The open end serves as the liquid inlet of the atomizing fluid channel 1, and multiple liquid outlet holes 110 are provided on the side wall between the open end and the closed end. The cross-section of the liquid outlet holes 110 includes, but is not limited to, circular, Y-shaped, cross-shaped, elongated, star-shaped, or rhomboid shapes.

[0032] Understandably, the metal tube 11 can be a straight tube or a bent tube. The metal tube 11 is made of food-grade material, such as stainless steel.

[0033] The porous ceramic 12 can be made by filling the metal tube 11 with ceramic raw materials (clay) and then solidifying the ceramic raw materials in the metal tube 11 through a sintering process to form a porous ceramic 12 that is not easily deformed. The porous ceramic 12 has a capillary effect, which can quickly absorb liquid. At the same time, the porous ceramic 12 reduces the flow cross-sectional area of ​​the metal tube 11, thereby reducing the rate at which the fluid passes through the metal tube 11.

[0034] In some embodiments, a height difference is predetermined between the end face of the porous ceramic 12 and the end face of the open end. For example... Figure 2 As shown, the end face of the porous ceramic 12 near the opening of the metal tube 11 defines a groove with the inner wall of the metal tube 11. When the atomizing fluid channel 1 is guided, the fluid quickly enters the groove, is then slowly absorbed by the porous ceramic 12, and is guided to the liquid outlet 110 through capillary action. The fluid is then released to the desired destination through the liquid outlet 110.

[0035] In some embodiments, the porous ceramic 12 is at least partially exposed at the open end of the metal tube 11. Specifically, as Figure 3 As shown, the porous ceramic 12 protrudes from the open end of the metal tube 11.

[0036] In some embodiments, the porous ceramic 12 at least partially penetrates the liquid outlet 110, exposed outside the metal tube 11. For example... Figure 4 As shown, a portion of the porous ceramic 12 protrudes from the metal tube 11 through the liquid outlet hole 110. Fluid is released outside the metal tube 11 through the capillary action of the porous ceramic 12.

[0037] At least one flow channel is defined between the porous ceramic 12 and the inner wall of the metal tube 11, and the flow channel is connected to the liquid outlet 110. The flow cross-sectional area formed by the flow channel is larger than the cross-sectional area of ​​the hole on the porous ceramic 12, allowing some liquid or air to flow quickly through the flow channel to the desired destination.

[0038] In some embodiments, such as Figure 5 As shown, the inner wall of the metal tube 11 is recessed, so that at least part of the inner wall forms a gap with the surface of the porous ceramic 12 to form a flow channel A111.

[0039] In some embodiments, such as Figure 6As shown, a flow channel B120 is formed by a depression on the surface of the porous ceramic 12. The flow channel B120 extends along the flow direction of the metal pipe 11 on the surface of the porous ceramic 12. The outer surface of the porous ceramic 12 quickly guides the liquid through the flow channel B120, while the micropores inside the porous ceramic 12 slow down and enhance the liquid storage.

[0040] On the other hand, this application also provides an atomizer 100, which includes a housing, a liquid storage chamber 1010 and an atomizing fluid channel 1 disposed within the housing, wherein the atomizing fluid channel 1 is at least partially disposed within the liquid storage chamber 1010, and the liquid storage chamber 1010 is used to store an atomizing matrix for generating an aerosol. The atomizing fluid channel 1 includes any of the above embodiments, and the liquid outlet 110 on the atomizing fluid channel 1 communicates with the liquid storage chamber 1010.

[0041] During the replenishment of the atomizing matrix in the atomizer 100, the atomizing matrix enters from the open end of the metal tube 11 and slowly penetrates into one end of the liquid outlet 110 under the capillary action of the porous ceramic 12, and is released from the liquid outlet 110 into the liquid storage chamber 1010.

[0042] In some embodiments, such as Figures 7-8 As shown, the atomizer 100 includes a first housing 101 having a liquid storage chamber 1010 and a second housing 102 having a liquid supply chamber 1020. The portion of the atomizing fluid channel 1 having a liquid outlet 110 is housed in the liquid storage chamber 1010, and the open end of the atomizing fluid channel 1 is used to connect to the liquid supply chamber 1020.

[0043] During the replenishment of the atomizing matrix in the atomizer 100, the open end of the atomizing fluid channel 1 is connected to the liquid supply chamber 1020. When the atomizing matrix flows, the porous ceramic 12 slows down the flow rate or velocity of the atomizing matrix between containers within the metal tube 11, and guides it to the liquid outlet 110 through capillary absorption by the porous ceramic 12. After the flow rate of the atomizing matrix is ​​reduced, it is less likely to overflow, and the gas in the container can also be discharged through the guide groove in the atomizing fluid channel 1.

[0044] In some embodiments, a liquid storage cotton is provided inside the liquid storage chamber 1010, and the atomizing fluid channel 1 is at least partially surrounded by the liquid storage cotton. The atomizing matrix is ​​fed into the liquid storage chamber 1010 through the liquid outlet 110 and is absorbed and stored by the liquid storage cotton.

[0045] In some embodiments, the atomizer 100 further includes a closure member for sealing the open end of the atomizing fluid channel 1. The closure member is detachably connected to the housing, for example, by a threaded connection, a plug-in connection, or other detachable means.

[0046] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
