Abstract

The application discloses a heat insulation pipe assembly and an electronic cigarette. The heat insulation pipe assembly is convenient to manufacture, saves manufacturing cost and has good heating effect.

Description

Heat insulation pipe assembly and electronic cigarette

Technical Field

The invention relates to the technical field of electronic cigarettes, in particular to a heat insulation pipe assembly and an electronic cigarette.

Background

Along with the development of the times, the health of individuals and others harmful to smoking becomes the mainstream cognition of society; electronic cigarettes are accepted by more and more smokers as alternative products to cigarettes.

The electronic cigarette is a non-burning electronic cigarette, has the efficacy similar to that of common cigarettes, can refresh, satisfies the smoking addiction, and enables smokers to produce euphoria and relaxation; the electronic cigarette mainly comprises tobacco tar (containing nicotine, essence, propylene glycol solvent and the like), a heating system, a power supply and a filter tip, wherein the cigarette is heated and baked through a heating tube of the heating system, and smoke is generated for a user to inhale, so that the same feeling as smoking is achieved.

The existing baking type electronic cigarette is characterized in that the cigarette oil is baked at the high temperature of 300-400 ℃ through the heating wire in the ceramic heating tube to achieve an atomization effect, but because the external temperature of the ceramic heating tube is very high, part of heat is lost through heat radiation and heat transfer, the shell and the circuit board are easy to heat, the temperature is increased, a user is easy to scald the hand when holding the electronic cigarette, and the circuit board is also easy to overheat to damage and fail; the electronic cigarette is difficult to generate enough smoke because of insufficient heating heat, and the user has poor smoking experience effect.

There are vacuum tube heat insulation modes on the market, but the vacuum heat insulation tube is complex in manufacturing process, is manufactured in a vacuum environment, has high requirements on equipment and environment during detection, and is inconvenient to produce.

Disclosure of Invention

The present invention provides a heat insulating tube assembly which aims to solve the above problems.

According to a first aspect of the present application, there is provided a heat insulation pipe assembly for an electronic cigarette, which includes an inner wall pipe, an aerogel member and an outer wall pipe, wherein the aerogel member is sleeved outside the inner wall pipe, and the outer wall pipe is sleeved outside the aerogel member and connected to the inner wall pipe.

In the heat insulating pipe assembly of the present invention, both ends of the outer wall pipe are welded to the outer wall pipe, respectively.

In the heat insulating pipe assembly of the present invention, the distance between the outer wall pipe and the inner wall pipe is equal to the thickness of the aerogel member.

In the heat insulating pipe assembly of the present invention, the inner wall pipe is a straight tubular member or a tubular member having a reduced mouth at both ends.

According to a second aspect provided by an embodiment of the present application, an electronic cigarette is provided, which includes the heat insulation pipe assembly described above.

The technical scheme provided by the embodiment of the application can have the following beneficial effects: compared with a vacuum tube scheme, the heat insulation tube component is low in manufacturing environment requirement, does not need to be manufactured in a vacuum environment, reduces power consumption for creating the vacuum environment, and is more environment-friendly; and the manufacturing process is simpler and more convenient, and simultaneously, the requirements on equipment and environment during detection are reduced.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

It is also to be understood that the terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be further understood that the term "and/or" as used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.

Referring to fig. 1-2, the present invention discloses a heat insulation pipe assembly 20 for an electronic cigarette, wherein the heat insulation pipe assembly 20 is sleeved outside a heating device (such as a tubular heating element, a sheet heating element, etc.) of the electronic cigarette. The heat insulating tube assembly 20 comprises an inner wall tube 21, an aerogel piece 22 and an outer wall tube 23 which are sequentially arranged from inside to outside, wherein the aerogel piece 22 is sleeved outside the inner wall tube, the outer wall tube 23 is sleeved outside the aerogel piece 22, the outer wall tube 23 is connected with the inner wall tube 21, a containing cavity for containing the aerogel piece is formed between the outer wall tube and the inner wall tube, and the aerogel piece 22 is sealed between the outer wall tube 23 and the inner wall tube 21.

The principle of the device is as follows: the heat generated by the heating device of the electronic cigarette is transferred to the inner wall tube 21 of the heat insulation tube assembly 20, the heat transfer effect is reduced and the heat loss is reduced through the heat insulation effect of the aerogel piece 22, so that the temperature of the outer wall tube 23 is very low, and the use of users is convenient. Through verification, the use effect of the technical scheme of the application is similar to that of the vacuum heat insulation pipe. Compared with the vacuum tube scheme, the technical scheme of the application has low requirements on the manufacturing environment, does not need to be manufactured in a vacuum environment, reduces the power consumption for creating the vacuum environment, is more environment-friendly, has simpler manufacturing process, and simultaneously reduces the requirements on equipment and environment during detection.

In an alternative embodiment, the ends of the outer wall tube 23 are joined by welding to seal the aerogel member 22 between the inner wall tube 21 and the outer wall tube 23. Dust can be generated after the aerogel is used for a long time, and leakage of the dust can be reduced by sealing the aerogel between the outer wall pipe 23 and the inner wall pipe 21, so that user experience is prevented from being influenced. The distance between the outer wall tube 23 and the inner wall tube 21 is approximately equal to the thickness of the aerogel member 22. The inner wall tube 21 is a straight tubular member or a tubular member having a reduced mouth at both ends.

While the invention has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
