Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a planar honeycomb ceramic heating element and atomizer. Background Technology

[0002] Existing ceramic heating elements typically have a large oil reservoir on the back of the heating resistor, as shown in Chinese utility model patent CN202120881237.0. This method does not allow for precise control of the oil conduction rate, which leads to inaccurate control of the amount of smoke. On the other hand, the contact area between the ceramic body and the e-liquid is small, resulting in limited smoke volume; and the possibility of leakage is relatively high. Utility Model Content

[0003] In view of the above situation, it is necessary to propose a planar honeycomb ceramic heating element and atomizer with easily controllable oil conduction rate.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a planar honeycomb ceramic heating element, comprising:

[0005] A ceramic body, one side of which has at least one set of honeycomb oil storage holes, each set of honeycomb oil storage holes including at least 2 oil storage holes, and the oil storage holes in each set of honeycomb oil storage holes are symmetrically arranged about the center of the ceramic body;

[0006] The heating resistor is exposed or protrudes from the side of the ceramic body facing away from the opening of the oil reservoir hole. The heating resistor includes a first lead, a heating body, and a second lead connected in sequence.

[0007] Furthermore, the honeycomb oil storage hole group includes a first honeycomb oil storage hole group and a second honeycomb oil storage hole group. The diameter of the first honeycomb oil storage hole group is larger than that of the second honeycomb oil storage hole group. The oil storage holes of the first honeycomb oil storage hole group and the oil storage holes of the second honeycomb oil storage hole group are arranged in rows and alternate with each other.

[0008] Furthermore, it also includes a third honeycomb oil storage hole group, the diameter of which is larger than that of the second honeycomb oil storage hole group and smaller than that of the first honeycomb oil storage hole group, and the oil storage holes of the third honeycomb oil storage hole group are located near the end of the ceramic body.

[0009] Furthermore, the depth of each group of honeycomb oil storage holes is the same.

[0010] Furthermore, the outer edge of the heating resistor is provided with several pins extending into the ceramic body.

[0011] Furthermore, the locking pin is in the shape of a "T" or "L".

[0012] Furthermore, the pins of the first and second pins are larger than the pins on the heating element.

[0013] Furthermore, there is a gap between the oil storage hole and the retaining foot.

[0014] Furthermore, the depth of the oil storage hole is 0.6-0.9 times the height of the ceramic.

[0015] This invention also provides an atomizer, including the aforementioned planar honeycomb ceramic heating element.

[0016] The beneficial effects of this utility model are as follows: a honeycomb oil storage hole group is opened on the ceramic body, each group of honeycomb oil storage holes has at least 2 oil storage holes, and the oil storage holes are symmetrically arranged, resulting in balanced heat generation and heat conduction. By controlling the diameter of the oil storage holes, the oil guiding rate can be controlled more precisely. Moreover, compared with the structure of the oil storage tank, the oil storage holes can increase the contact area between the ceramic body and the e-liquid, thereby enabling a larger amount of smoke, and the e-liquid is less likely to leak from the outer wall of the ceramic body.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of a planar honeycomb ceramic heating element and atomizer, in conjunction with the accompanying drawings and embodiments, is provided. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0027] Please refer to Figures 1-5 A planar honeycomb ceramic heating element, comprising:

[0028] The ceramic body 100 has at least one set of honeycomb oil storage hole groups 110 on one side. Each set of honeycomb oil storage hole groups 110 includes at least two oil storage holes 114. The oil storage holes 114 in each set of honeycomb oil storage hole groups 110 are symmetrically arranged with respect to the center of the ceramic body 100.

[0029] The heating resistor 200 is exposed or protrudes from the side of the ceramic body 100 facing away from the opening of the oil reservoir 114. The heating resistor 200 includes a first pin 210, a heating body 220 and a second pin 230 connected in sequence.

[0030] A honeycomb oil storage hole group 110 is formed on the ceramic body 100. Each honeycomb oil storage hole group 110 has at least two oil storage holes 114, and the oil storage holes 114 are symmetrically arranged to achieve heat generation and heat conduction balance. By controlling the pore size of the oil storage holes 114, the oil guiding rate can be controlled more precisely. Moreover, compared with the structure of the oil storage tank, the oil storage holes 114 can increase the contact area between the ceramic body 100 and the e-liquid, thereby enabling a larger amount of smoke and making it less likely for the e-liquid to leak from the outer wall of the ceramic body 100.

[0031] Please refer to Figure 1 and Figure 3 The honeycomb oil storage hole group 110 includes a first honeycomb oil storage hole group 111 and a second honeycomb oil storage hole group 112. The diameter of the pores in the first honeycomb oil storage hole group 111 is larger than that in the second honeycomb oil storage hole group 112. The oil storage holes 114 of the first honeycomb oil storage hole group 111 and the oil storage holes 114 of the second honeycomb oil storage hole group 112 are arranged in rows and alternate with each other. The combination of large and small holes can increase the amount of smoke through the large holes and control the oil guiding rate more precisely through the small holes.

[0032] Please refer to Figure 1 and Figure 3It also includes a third honeycomb oil storage hole group 113. The diameter of the third honeycomb oil storage hole group 113 is larger than the diameter of the second honeycomb oil storage hole group 112 but smaller than the diameter of the first honeycomb oil storage hole group 111. The oil storage holes 114 of the third honeycomb oil storage hole group 113 are located near the end of the ceramic body 100. The sidewall of the ceramic body 100 at the end generally has a thicker thickness, and setting a larger hole diameter can increase the amount of smoke. It is understood that each honeycomb oil storage hole group 110 can be arranged horizontally or vertically. When arranged horizontally, the third honeycomb oil storage hole group 113 is located at the top and bottom ends; when arranged vertically, the third honeycomb oil storage hole group 113 is located at the left and right ends.

[0033] Preferably, the depth of each group of honeycomb oil storage holes 110 is the same. This reduces variables, allowing the oil guiding rate to be controlled only by the hole diameter, which is convenient for calculation, precise for control, and can also reduce leakage.

[0034] Generally, the heating resistor 200 can be mounted on the ceramic body 100 using a printing process, or it can be integrally formed with the ceramic body 100 using a sintering process. For details, please refer to [link / reference needed]. Figure 4 and Figure 5 The heating resistor 200 has several retaining feet 240 extending into the ceramic body 100 along its outer edge. That is, the retaining feet 240 are sintered inside the ceramic body 100. Generally, when the heating resistor 200 is arranged horizontally, the retaining feet 240 are usually located at the upper and lower ends of the heating resistor 200.

[0035] Please refer to Figure 4 The 240 clamping feet are in a "T" or "L" shape. This design uses horizontal retaining strips to improve connection stability, and the process is simple and convenient, requiring only cutting or stamping.

[0036] Please refer to Figure 4 The locking pin 240 of the first pin 210 and the second pin 230 is larger than the locking pin 240 on the heating body 220. Setting a larger locking pin 240 on the pin provides greater stability.

[0037] Please refer to Figure 5 There is a gap between the oil reservoir 114 and the retaining foot 240. This is to prevent the retaining foot 240 from directly contacting the e-liquid, which would cause the ceramic body 100 to lose its filtering effect. Understandably, this gap can be a height gap or a horizontal gap.

[0038] Preferably, the depth of the oil storage hole 114 is 0.6-0.9 times the height of the ceramic.

[0039] Typically, both the ceramic body 100 and the heating resistor 200 can be made of existing materials. For example, the ceramic body 100 can be made of quartz as the main component, and the heating resistor 200 can be made of nickel-chromium alloy. The first pin 210 and the second pin 230 can be electroplated with copper, silver or gold as needed to improve conductivity.

[0040] The first pin 210 and the second pin 230 are generally in the form of a sheet. The shape of the heating body 220 can be set as needed, preferably a mesh, a continuous S-shape, a continuous triangle, a square waveform, etc.

[0041] Understandably, the oil reservoir 114 can be configured according to the heating resistor 200. Specifically, the depth, aperture, and array shape of the oil reservoir 114 can be designed according to the shape of the heating resistor 200, heat conduction, etc.

[0042] This invention also provides an atomizer, including the aforementioned planar honeycomb ceramic heating element.

[0043] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0044] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0045] In summary, the planar honeycomb ceramic heating element provided by this utility model has honeycomb oil storage hole groups on the ceramic body. Each group of honeycomb oil storage holes has at least two oil storage holes, and the oil storage holes are symmetrically arranged, resulting in balanced heat generation and conduction. By controlling the diameter of the oil storage holes, the oil guiding rate can be controlled more precisely. Moreover, compared with the oil storage tank structure, the oil storage holes can increase the contact area between the ceramic body and the e-liquid, thereby enabling a larger amount of smoke and preventing the e-liquid from leaking from the outer wall of the ceramic body.
