This part of the temperature rise is heat loss, which is not conducive to improving thermal efficiency. The heat is eventually transferred to the plastic parts in contact with the metal electrode. Long-term use will easily cause the plastic to age, affecting the product's service life. Utility Model Content

[0034] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0035] Example:

[0036] See also Figure 1 An embodiment of the utility model provides an electronic atomization device, including an atomizer 10 and a power supply assembly 20, wherein the power supply assembly 20 is electrically connected to the atomizer 10. Specifically, the power supply assembly 20 and the atomizer 10 may be detachably connected or non-detachably connected, and the present application does not impose any specific limitation on this.

[0037] See also Figures 2 to 7 The atomizer 10 includes an oil cup 1 and an atomizer assembly 2. The oil cup 1 is provided with a liquid storage chamber 11; the atomizer assembly 2 includes an atomizer core 21 and an electrode assembly 22, the atomizer core 21 is in liquid communication with the liquid storage chamber 11, the atomizer core 21 is in contact with and electrically connected to the electrode assembly 22, a portion of the electrode assembly 22 is located in the liquid storage chamber 11, and a portion of the electrode assembly 22 is located outside the liquid storage chamber 11 and is electrically connected to the power supply assembly 20, so that the power supply assembly 20 supplies power to the atomizer core 21.

[0038] Since the electrode assembly 22 is partially located in the liquid storage chamber 11 and the atomizer core 21 is in contact with the electrode assembly 22, when the atomizer core 21 is working, the heat conducted from the atomizer core 21 to the electrode assembly 22 can be conducted to the atomized liquid stored in the liquid storage chamber 11, thereby preheating the atomized liquid; moreover, the power supply assembly 20 supplies power to the atomizer core 21 through the electrode assembly 22, so that the electrode assembly 22 serves as both a conductive component of the atomizer core 21 and a preheating component of the atomized liquid, thereby simplifying the structure. At the same time, the heat generated by the electrode assembly 22 itself during conduction and the heat conducted by the atomizer core 21 can be conducted to the atomized liquid through the portion located in the liquid storage chamber 11, thereby reducing energy loss and improving energy utilization.

[0039] It should be noted that the atomizer core 21 can be made of conductive ceramics that can conduct electricity and generate heat as a whole, foam metal, non-conductive porous glass, ordinary porous ceramics and other materials. When the atomizer core 21 is made of ceramics, for the atomizer liquid with a high viscosity, it has great resistance to the bubbles generated during the ventilation process, causing the bubbles to be stuck on the ceramic surface and unable to rise, hindering the ceramic from continuously absorbing the atomizer liquid. When the atomizer liquid is preheated and the temperature rises (for example, the temperature reaches 50°C), the viscosity will drop significantly, thereby avoiding the poor liquid flow due to the high viscosity of the atomizer liquid, and further avoiding the dry burning of the ceramic due to insufficient liquid supply.

[0040] See also Figure 3 , Figure 4 and Figure 6 The electrode assembly 22 is provided with a clamping structure, and the atomizer core 21 is fixedly connected to the electrode assembly 22 through the clamping structure, so that the atomizer core 21 is fixed to the electrode assembly 22 by using the clamping structure, and the integrated assembly of the atomizer assembly 2 can be realized. The atomizer assembly 2 also includes a fixing frame 23; the electrode assembly 22 is provided with two electrode members 222, one of the two electrode members 222 is a positive electrode, and the other is a negative electrode. The two electrode members 222 are fixed to the fixing frame 23 and are spaced apart. The clamping structure is a clamping groove 221 provided between the two electrode members 222, and the atomizer core 21 is clamped and fixed in the clamping groove 221, so that the atomizer core 21 is clamped and fixed by the two electrode members 222.

[0041] In some embodiments, at least a portion of at least one electrode member 222 is located in the liquid storage chamber 11. For example, a portion of one electrode member 222 may be located in the liquid storage chamber 11, or portions of two electrode members 222 may be located in the liquid storage chamber 11. Figure 4 As shown, preferably, parts of the two electrode members 222 are both located in the liquid storage chamber 11, which is beneficial for preheating the atomized liquid.

[0042] See also Figure 6 and Figure 7The electrode member 222 is a metal sheet. The sheet shape of the electrode member 222 can make it have excellent elasticity, which can prevent the problem of ceramic cracking caused by excessive contact pressure between the electrode member 222 and the atomizer core 21; moreover, the fixing frame 23 is a plastic part. The sheet-shaped electrode member 222 can be fixed inside the fixing frame 23 by injection molding to prevent leakage due to assembly gaps. The electrode member 222 is made of metal and has excellent thermal conductivity and electrical conductivity.

[0043] See also Figure 5 , Figure 6 and Figure 7 In some embodiments, a clamping groove 2221 is provided on one side of the two electrode members 222 that are arranged opposite to each other, and the two clamping grooves 2221 form at least a part of the clamping groove 221, wherein the clamping groove 221 is adapted to the atomizer core 21, and the inner wall of the clamping groove 221 supports and clamps the atomizer core 21. According to actual needs, the clamping groove 2221 can be formed by bending the electrode member 222, for example, first bending the electrode member 222 by 90° in a direction perpendicular to its thickness direction, then bending the electrode member 222 by 90° in a length direction, and then bending the electrode member 222 by 90° in a direction perpendicular to its thickness direction, thereby bending to form the clamping groove 2221; the side wall of the clamping groove 2221 and its opening adjacent to each other supports the atomizer core 21.

[0044] It should be understood that by providing a card slot 2221 on the electrode sheet and utilizing the card space to card the atomizer core 21, the atomizer core 21 can be supported by the side wall provided adjacent to the card slot 2221 and its opening, so that it is not necessary to closely match with the bottom plate of the atomizer core 21, and the ceramic atomizer core 21 can be prevented from being broken due to overpressure during assembly. In addition, the sheet-shaped electrode member 222 can be bent to form the card slot 2221, or it can be bent to form a contact portion 2226 that contacts the power supply component 20, and the power supply component 20 can be a battery rod, so that the outlet position connected to the battery rod PIN pin is not affected by the assembly position, and can be set arbitrarily, with stronger compatibility.

[0047] It should be noted that when the atomizer core 21 is made of conductive ceramics, foam metal and other materials that can conduct electricity and generate heat as a whole, the atomizer core 21 does not need to be separately provided with a heating part connected between the two pins 212; when the atomizer core 21 is made of non-conductive porous glass, ordinary porous ceramics and other materials, a heating part connected between the two pins 212 needs to be provided.

[0048] See also Figure 3 , Figure 4 and Figure 5 The electrode member 222 is provided with a hollow structure, wherein the hollow structure of the portion of the electrode member 222 located in the liquid storage chamber 11 forms a transmission hole 2223, and the transmission hole 2223 runs through the thickness direction of the electrode member 222. The transmission hole 2223 is used to provide a delivery channel for the atomized liquid, which can prevent the uneven drop in the liquid level of the atomized liquid around one end of the electrode member 222 extending into the liquid storage chamber 11; the hollow structure of the portion of the electrode member 222 located outside the liquid storage chamber 11 forms a through hole 2224, and the through hole 2224 can reduce heat loss and heating resistance.
