Description

Technical Field

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

[0002] Ceramic atomizers are widely used heating devices in electronic cigarettes. They offer uniform heating, strong chemical stability, and fine atomization. Traditional ceramic atomizers use a single piece of ceramic with a heating resistor on one side for heating, relying on the microporous structure of the ceramic itself for liquid intake. This method results in a slow liquid intake rate and is only suitable for low-concentration liquids.

[0003] To improve the liquid inlet rate and accommodate liquids with higher concentrations, the existing method is to create a large-capacity oil reservoir on the ceramic heating element, but this method still cannot meet market demands. Utility Model Content

[0004] In view of the above situation, it is necessary to propose a ceramic heating element suitable for high-concentration liquid atomization.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a ceramic heating element, one end of which is a heating end and the other end is a liquid inlet end. The liquid inlet end is provided with a groove that opens away from the heating end. The groove has an expansion section that expands in the direction away from the heating end. The liquid inlet end is provided with a plurality of liquid inlet holes.

[0006] Furthermore, the groove also includes a liquid storage section that extends outward along the end of the expansion section away from the heating end.

[0007] Furthermore, the liquid storage section and the expansion section are connected by a concave arc surface transition.

[0008] Furthermore, the end face of the liquid inlet, the expansion section, and the bottom of the groove are all provided with a plurality of liquid inlet holes.

[0009] Furthermore, the depth of several of the liquid inlet holes is the same, and the bottom of the liquid inlet hole is 0.8-1.2 mm away from the heating end.

[0010] Furthermore, the two opposite edges of the liquid inlet end are provided with side grooves.

[0011] Furthermore, the expansion segment expands outward in the form of an inclined plane or a concave arc.

[0012] Furthermore, the outer contour of the groove is waist-shaped, elliptical, or a symmetrical polygon.

[0013] Furthermore, the heating end is provided with a heating resistor, which is sintered with the ceramic heating element, and the outer edge of the heating resistor is provided with several claws extending into the ceramic heating element.

[0014] Furthermore, the liquid inlet is positioned away from the clamping claw.

[0015] The beneficial effects of this invention are as follows: the liquid inlet end of the ceramic heating element adopts a combination of groove and liquid inlet hole, which further increases the liquid inlet volume and the contact area between the ceramic heating element and the liquid, allowing the ceramic heating element to make deeper contact with the liquid, fully improving the utilization rate of the ceramic heating element, making it suitable for high-concentration liquids, and generating a larger amount of smoke. The groove is provided with an expansion section, which not only increases the volume of the groove, but also facilitates the entry of liquid and improves the liquid conduction rate.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the ceramic heating element of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] Please refer to Figures 1-5 A ceramic heating element 100, one end of which is a heating end 110 and the other end is a liquid inlet end 120. The liquid inlet end 120 is provided with a groove 121 that opens away from the heating end 110. The groove 121 has an expansion section 1212 that expands in the direction away from the heating end 110. The liquid inlet end 120 is provided with a plurality of liquid inlet holes 122.

[0027] The liquid inlet 120 of the ceramic heating element 100 adopts a combination of a groove 121 and a liquid inlet hole 122, which further increases the liquid inlet volume and the contact area between the ceramic heating element 100 and the liquid. This allows the ceramic heating element 100 to have deeper contact with the liquid, fully improving the utilization rate of the ceramic heating element 100. It is suitable for high-concentration liquids and can generate a larger amount of smoke. The groove 121 is provided with an expansion section 1212, which not only increases the volume of the groove 121, but also facilitates the entry of liquid and improves the liquid conduction rate.

[0028] Please refer to Figure 2 and Figure 4 , Figure 5 The groove 121 also includes a liquid storage section 1211, which extends outward along the end of the expansion section 1212 away from the heating end 110. The liquid storage section 1211 increases the capacity of the groove 121 and makes it easier for the liquid inlet hole 122 within the groove 121 to absorb liquid. Generally, the liquid storage section 1211 extends vertically outward, or it extends obliquely outward with an angle smaller than the angle of the expansion section 1212.

[0029] Please refer to Figure 2 and Figure 4 , Figure 5 The liquid storage section 1211 and the expansion section 1212 are connected by a concave arc surface. This facilitates the smooth passage of liquid into the bottom of the groove 121. Preferably, the depth of the expansion section 1212 is the same as the depth of the liquid storage section 1211.

[0030] Please refer to Figure 1 and Figure 2 The end face of the liquid inlet 120, the expansion section 1212, and the bottom of the groove 121 are all provided with a number of liquid inlet holes 122. It can be understood that the liquid inlet holes 122 are mainly concentrated in the groove 121, that is, the bottom of the groove 121 and the expansion section 1212, and a few are provided on the end face of the liquid inlet 120 according to the residual area.

[0031] Preferably, the various inlet holes 122 have the same depth, and the bottom of each inlet hole 122 is 0.8-1.2 mm away from the heating end 110. With the inlet holes 122 having the same depth, the guide flow rate can be more precisely controlled simply by adjusting the diameter of the inlet holes 122. The 0.8-1.2 mm distance between the inlet holes 122 and the end face of the heating end 110 prevents leakage.

[0032] Please refer to Figure 1 The liquid inlet end 120 has two opposite edges with side grooves 123. The side grooves 123 can facilitate the installation and positioning of the ceramic heating element 100, that is, they can be used as limiting grooves and / or positioning grooves.

[0033] Preferably, the expansion section 1212 expands outward with an inclined surface or a concave arc surface. The inclination angle of the expansion section 1212 is generally 30-60 degrees, preferably 45 degrees.

[0034] Preferably, the outer contour of the groove 121 is waist-shaped, elliptical, or a symmetrical polygon. This improves the uniformity of liquid inflow.

[0035] Please refer to Figures 3-5 The heating end 110 is provided with a heating resistor 200, which is sintered integrally with the ceramic heating element 100. The outer edge of the heating resistor 200 is provided with several claws 240 extending into the ceramic heating element 100. Generally, the heating resistor 200 includes an integrally formed positive electrode 210, a main body 220, and a negative electrode 230. Claws 240 can be provided on the positive electrode 210, the main body 220, and the negative electrode 230.

[0036] Please refer to Figures 3-5 The liquid inlet 122 is positioned to avoid the clamp 240. Preferably, the clamps 240 on the positive and negative electrodes are horizontally offset to avoid the liquid inlet 122, and the clamps 240 on the main body 220 have a height gap with the liquid inlet 122.

[0037] The liquid inlet holes 122 are generally arranged in an orderly manner. Please refer to... Figure 2 It has 7 rows of inlet holes 122, with the same diameter for inlet holes in the same row. The diameter of the inlet hole 122 located in the middle of the bottom of the groove 121 (i.e., the 4th row from the left) is 0.7 mm, the diameter of the two inlet holes 122 on both sides of the bottom of the groove 121 is 0.8 mm, the diameter of the inlet hole 122 on the expansion section 1212 is 0.6 mm, and the diameter of the two inlet holes 122 on the end face is 0.7 mm. Alternatively, the diameter of the inlet holes 122 gradually decreases from the middle to both sides.

[0038] 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.

[0039] 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.

[0040] In summary, the ceramic heating element provided by this utility model employs a combination of a groove and an inlet hole at its liquid inlet end, further increasing the liquid inlet volume and the contact area between the ceramic heating element and the liquid. This allows for deeper contact between the ceramic heating element and the liquid, significantly improving its utilization rate. It is suitable for high-concentration liquids and can generate a larger amount of smoke. The groove is designed with an expansion section, which not only increases the volume of the groove but also facilitates liquid entry and improves the liquid conduction rate.
