Description

Technical Field

[0001] This utility model relates to electronic cigarettes, specifically to an electronic cigarette heating tube with a thermal buffer zone. Background Technology

[0002] Current e-cigarettes typically consist of a tobacco section and a sponge filter. Ideally, when the e-cigarette is heated inside the heating element, only the tobacco section is heated. However, in reality, some heat is always conducted through the heating element to the sponge filter, which heats the sponge and produces an off-flavor, affecting the taste of the e-cigarette. Summary of the Invention

[0003] The purpose of this invention is to provide an electronic cigarette heating tube with a heat buffer zone to overcome the defect of existing electronic cigarette heating tubes where the heating sponge affects the taste.

[0004] To achieve the aforementioned objectives, the technical solution of this utility model is as follows: An electronic cigarette heating element with a thermal buffer zone includes a tube body and a heating element. The heating element is fixed to the outside of the tube body and to one end of the tube body. The other end of the tube body has several annular perforations. The annular perforations are composed of several through holes arranged circumferentially along the tube body. The length of the connecting area between the through holes in the circumferential direction of the tube body is less than the length of the through holes in the circumferential direction of the tube body. The annular perforations are parallel to each other, and the through holes of each annular perforation are opposite to the connecting areas of the adjacent annular perforations in the axial direction of the tube body.

[0005] Furthermore, the through hole is rectangular or elliptical in shape.

[0006] Furthermore, the through hole is a slit.

[0007] Furthermore, the width of the slit in the axial direction of the tube body is 10-1000 μm.

[0008] Furthermore, the through holes have the same length in the axial direction of the pipe body, and the adjacent area has the same length in the circumferential direction of the pipe body.

[0009] Furthermore, the ratio of the length of the adjoining area in the circumferential direction of the pipe body to the length of the through hole in the axial direction of the pipe body is 1:1.1-100.

[0010] Furthermore, the tube body is made of aluminum, aluminum alloy, titanium, or titanium alloy, and the surface of the tube body has a ceramic coating formed by AO / MAO / TECO treatment.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows: This invention relates to an electronic cigarette heating tube with a heat buffer zone. The heating element is located at one end of the tube body, while the other end consists of a heat buffer zone composed of multiple ring-shaped perforations. When the heating element heats the tobacco at one end of the tube body, the heat generated is blocked by the heat buffer zone and does not heat the sponge at the other end of the tube body. This solves the problem in existing electronic cigarettes where heating the sponge produces an off-flavor that affects the taste of the cigarette. Attached Figure Description

[0014] Example

[0015] like Figure 1 and 2 As shown, an electronic cigarette heating element with a heat buffer zone includes a tube body 1 and a heating element 2. The heating element 2 is fixed to one end of the outer side of the tube body 1, and the other end of the tube body 1 has a heat buffer zone 3 composed of several annular perforations. The annular perforations consist of several through holes 301 arranged circumferentially along the tube body 1, and the length of the connecting area 302 between the through holes 301 in the circumferential direction of the tube body is less than the length of the through holes 301 in the circumferential direction of the tube body. The annular perforations are parallel to each other, and in the axial direction of the tube body, the through holes 301 of each annular perforation are opposite to the connecting areas 302 of the adjacent annular perforations.

[0016] The through-hole 301 is a slit of uniform length. The tube body 1 is made of aluminum alloy, and its surface has a ceramic coating formed by TECO treatment. The advantage of this treatment is that the slit can be made on the tube body first, followed by TECO treatment. An insulating ceramic coating will be simultaneously formed on the inner wall, outer wall, and edges of the slit of the tube body 1, facilitating the subsequent layering of the heating element 2 circuitry (such as wrapping a mesh heating wire or printing heating traces) on the outer side of the tube body. The minimum width of the slit varies depending on the oxidation process used (length refers to the distance between the front and rear ends of the through-hole in the circumferential direction of the tube body, and width refers to the distance between the two sides of the through-hole in the axial direction of the tube body). For example, with TECO treatment, the minimum width of the slit can be as low as 10μm, while the maximum width is limited by the tube body material and the overall structural strength of the tube body.

[0017] When the heating element 2 heats the tobacco at one end of the tube 1, heat is conducted from one end of the tube 1 to the other end through the connecting areas of each ring. However, the heat conduction path is greatly restricted by the slits between adjacent connecting areas. The shorter the length of the connecting area 302, the better the heat barrier effect of the heat buffer (but similarly, the minimum length of the connecting area 302 is also limited by the tube material and the overall structural strength of the tube). After being blocked by the slits, the heat generated at one end of the tube is difficult to conduct to the other end due to the heat buffer 3, and will not heat the sponge at the other end of the tube. This solves the problem of existing electronic cigarettes where heating the sponge produces an odor that affects the taste of the cigarette.
