Problems solved by technology

When the vent hole is blocked, it is difficult for the outside cold air to enter, so that only the heated and atomized smoke escapes downstream from the vent hole without the outside air to carry and cool it. In this case, the temperature of the sucked smoke will increase Too high, the concentration is high, the suction resistance is large, which seriously affects the suction experience
Most of the existing solutions use the method of preheating the heating element, but this method will greatly increase the cost of the entire atomization device, and it cannot fundamentally solve the problem that the vent hole is blocked and cannot be pumped

Embodiment 1

[0047] like figure 1 As shown, a composite heating element 1 with multiple air holes includes a ceramic substrate 101 and a heating element 102 . The ceramic substrate 101 is a hollow columnar structure, made of alumina, and has a diameter of 5 mm.

[0048] The ceramic base 101 is provided with two ventilation holes, one of which runs through the center of the ceramic base 101 and is the main ventilation hole 10102 , with a diameter of 2 mm, a material selected from alumina, a porosity of 55%, and a pore diameter of 35 μm. Two auxiliary ventilation holes 10101 are provided bypassing the main ventilation hole 10102 , and the auxiliary ventilation holes 10101 penetrate through the ceramic base 101 and are parallel to the main ventilation hole 10102 .

[0049] The auxiliary ventilation hole 10101 is also inserted with an auxiliary ventilation pipe 103 whose wall material is impermeable to e-liquid, the height of the auxiliary ventilation pipe 103 is not less than the height of t...

Embodiment 2

[0053] The preparation method of a composite heating element with multiple ventilation holes described in Embodiment 1, the method comprises the following steps:

[0054] (1) At least one auxiliary ventilation tube 103 is prepared by injection molding or die casting or sintering or machining.

[0055] (2) Obtaining the first ceramic body by injection molding or tape casting, and opening the longitudinal center of the first ceramic body to form the main ventilation hole 10102, and at the same time embedding the auxiliary ventilation pipe 10101 in the first ceramic body The bypass of the body main vent hole 10102 obtains the second ceramic green body.

[0056] (3) The heating element is embedded on the surface of the main vent hole to obtain a third ceramic body.

[0057] (4) Sintering and molding the third ceramic green body to obtain a composite heating element with multiple air holes.

Embodiment 3

[0059] like Figure 5 As shown, an atomizing device with a composite heating element with multiple ventilation holes. The device includes a composite heating body 1 , an air pipe 2 , an oil storage bin 3 , a sealing silicone 4 , a suction nozzle 5 and a power source 6 .

[0060] The oil storage bin 3 is a hollow structure, and the upper part is tightly connected with the sealing silica gel 4 .

[0061]The composite heating element 1 is located inside the airway pipe 2 and has a hollow columnar structure. The axial outer surface of the composite heating element 1 is a liquid absorption surface, and the axial inner surface of the main vent hole 10102 is an atomizing surface.

[0062] The air duct 2 is a hollow tubular structure, located inside the oil storage bin, with oil inlet holes on both sides, and a composite heating element 1 on the inner side.

[0063] The power supply 6 is installed at the bottom of the entire atomizing device for controlling the output of the entire ...

Abstract

The invention provides a composite heating element with multiple vent holes and a preparation method thereof, the heating element comprises a ceramic substrate (101) and a heating element (102), the ceramic substrate (101) is provided with at least two vent holes, one vent hole is a main vent hole (10102) and longitudinally penetrates through the ceramic substrate (101); at least one auxiliary vent hole (10101) is further formed in a bypass of the main vent hole (10102), the auxiliary vent hole (10101) also longitudinally penetrates through the ceramic base body (101), and an auxiliary vent pipe (103) is arranged in the auxiliary vent hole (10101), and the wall material of the auxiliary vent pipe (103) does not permeate tobacco tar. According to the composite heating body, the auxiliary ventilation pipe is additionally arranged, tobacco tar can be isolated and prevented from permeating, and the problem that a ventilation hole of an existing electronic atomization device is blocked due to tobacco tar permeation and aerogel condensation, and suction cannot be achieved is solved. The preparation method of the composite heating body is simple and is very suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of electronic atomization, and in particular relates to a composite heating element with multiple ventilation holes. Background technique [0002] Electronic atomization refers to the atomization of liquid into small aerogel particles by heating or ultrasonic vibration. With the continuous improvement and innovation of atomization technology, the technology has been widely used in the field of household and medical treatment, such as humidifiers, aroma diffusers and medical atomization treatment. [0003] The electronic atomization device is mainly composed of an atomizer and a power supply, and the core component of the atomizer is a heating body. At present, most of the heating elements of electronic atomization devices on the market are made of porous ceramics. However, the overall performance of the ceramic heating element is poor, especially the existing vertical ceramic heating element, which is gene...
