[0002] Electronic atomizers are increasingly pursuing low resistance, high burst and large capacity. For large capacity, the larger the amount of oil, the greater the oil pressure, and the more likely it is to leak during product transportation; it is also very easy to have abnormalities such as gurgling, oil flying, and oil explosion during inhalation. Therefore, whether it is the atomizer core, integrated cotton, the entire oil cup or even the entire device, it is necessary to maintain air pressure balance. At present, after smoking or in high and low temperature environments, a conventional atomizer will form a negative pressure in the oil storage tank, and the high pressure in the oil storage chamber cannot be discharged or the low pressure in the oil storage chamber has no air replenishment, which will cause the oil to fail to quickly enter the heating core. Smoking again will burn the heating core due to insufficient oil supply, and there will be oil leakage problems. Utility Model Content

[0019] In order to make the purpose, technical solution and advantages of the embodiments disclosed in the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present utility model.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0021] The electronic atomizer includes a battery module (not shown), an oil cup assembly (not shown) and an atomizer core assembly 100. The atomizer core assembly 100 and the oil cup assembly are combined to form an atomizer body, wherein the oil cup assembly contains smoke oil, and the atomizer core assembly 100 is upright and fixed in the middle of the oil cup. The atomizer core assembly 100 can heat the atomized smoke oil to generate smoke. The oil cup assembly is located on the outer peripheral side of the atomizer core assembly 100 and is also filled with integrated cotton. The integrated cotton is a plant fiber with strong oil absorption ability. The smoke oil is locked in the integrated cotton to reduce the fluidity of the smoke oil and reduce the risk of leakage of the atomizer.

[0022] As the core component of the electronic atomizer, the atomizer core assembly 100 can heat the e-liquid to generate aerosol for the user to inhale. The quality of the aerosol generation is closely related to the atomizer core assembly 100. The present disclosure provides an atomizer core assembly 100 including an internally hollow atomizer tube 3, an oil-conducting cotton 2 and a heating element 1. The oil-conducting cotton 2 is a hub for the transfer of e-liquid. Under the action of capillary action, the e-liquid on the integrated cotton is transported to the heating element 1. The heating element 1 is heated to generate heat to atomize the e-liquid into an aerosol for the user to inhale. The heating element 1 is a mesh with a preset structure. During assembly, the flat mesh heating element 1 is first laid flat on the middle of the oil-conducting cotton 2, and then a cylindrical supporting rod is placed in the middle of the heating element 1. The oil-conducting cotton 2 and the heating element 1 are wrapped together with the supporting rod and then inserted into the atomizer tube 3 for fixing, and then the excess oil-conducting cotton 2 is cut off with pliers. The oil-conducting cotton 2 after winding has a cylindrical oil-conducting body 21 and a long strip-shaped clamping portion 22 located on one side of the oil-conducting body 21. The atomizing tube 3 is a cylindrical tube with a hollow interior. A plurality of oil inlet holes 311 are arranged at intervals along the circumferential side wall of the atomizing tube 3 in the middle of the atomizing tube 3. The side wall of the atomizing tube 3 is provided with at least one pressure relief hole 312, and the pressure relief hole 312 is located at one end of the oil inlet hole 311. Figure 1 As shown, the atomizer core assembly 100 includes a heating element 1, an oil-conducting cotton 2 and an atomizer tube 3 from the inside to the outside. The heating element 1 is wound into a cylindrical shape, and the oil-conducting cotton 2 wraps the heating element 1. When the oil-conducting cotton 2 is embedded in the atomizer tube 3, the outer side of the oil-conducting cotton 2 fits with the hole wall of the oil inlet hole 311, so that the smoke oil can quickly flow from the oil inlet hole 311 to the oil-conducting cotton 2. Each pressure relief hole 312 is located above the oil-conducting cotton 2 and does not overlap with the oil-conducting cotton 2. It can be understood that when the oil-conducting cotton When the atomizer tube 2 is inserted into the atomizer tube 3, the oil-conducting cotton 2 does not contact the pressure relief hole 312, the pressure relief hole 312 is completely unobstructed, and there is a gap between the outer wall of the atomizer tube 3 and the oil-conducting cotton 2. In this way, when negative pressure appears in the atomizer core assembly 100, the gas can be exhausted through the pressure relief hole 312 in the atomizer tube 3, thereby maintaining the air pressure balance in the oil tank. Of course, the smoke oil in the oil cup can also enter the end of the oil-conducting cotton 2 through the pressure relief hole 312, which can accelerate the oil guiding rate.

[0023] In one embodiment, see Figure 1-3, the number of the pressure relief holes 312 is the same as the number of the oil inlet holes 311. Optionally, the number of the oil inlet holes 311 and the number of the pressure relief holes 312 are two respectively, and the two oil inlet holes 311 and the two pressure relief holes 312 are symmetrically distributed on the side wall of the atomization tube 3, respectively, and the oil inlet hole 311 and the pressure relief hole 312 closest to it are coaxially distributed. The atomization tube 3 is divided into an upper end 33 and a corresponding lower end 34. When the atomization tube 3 is placed upright, the pressure relief hole 312 is located above the oil inlet hole 311. Furthermore, any one of the pressure relief holes 312 and the corresponding oil inlet hole 311 are interconnected to form an annular opening 31. It can be understood that when the oil-conducting cotton 2 is inserted into the atomizing tube 3, most of the openings 31 are blocked by the oil-conducting cotton 2, while the remaining openings 31 are located in the oil-conducting cotton 2 and are not blocked, that is, the openings 31 are set higher than the oil-conducting cotton 2, and the blocked portion at the openings 31 is configured as an oil inlet hole 311, while the unblocked portion at the openings 31 is configured as a pressure relief hole 312. Here, the gas can be exhausted through the pressure relief hole 312 on the atomizing tube 3 to maintain the air pressure balance of the oil tank. The pressure relief hole 312 also has an oil guiding function, and the smoke oil in the oil-conducting cotton 2 can also enter the end of the oil-conducting cotton 2 through the pressure relief hole 312 to speed up the oil guiding speed. This structure is ingenious and low-cost, and does not require additional pressure relief holes 312.

[0024] Specifically, the end of the pressure relief hole 312 farthest from the oil-conducting cotton 2 is the highest point of the pressure relief hole 312, and the distance from the highest point of the pressure relief hole 312 to the closest end of the oil-conducting cotton 2 is H, where H≧0.5 cm, so that the pressure relief hole 312 can be effectively formed to facilitate exhaust.

[0025] Furthermore, two slots 32 are provided in the atomizing tube 3 . Figure 3 As shown, two slots 32 and two openings 31 are spaced apart on the side wall of the atomizer tube 3. The slot 32 extends from the upper end 33 of the atomizer tube 3 to the lower end 34 of the atomizer tube 3, but does not penetrate the entire atomizer tube 3. The slot 32 is V-shaped or U-shaped. When the oil-conducting cotton 2 wrapped with the heating element 1 is assembled into the atomizer tube 3, the clamping portion 22 of the oil-conducting cotton 2 is embedded into one of the slots 32, so that the oil-conducting cotton 2 is firmly fixed in the atomizer tube 3. The clamping portion 22 on the oil-conducting cotton 2 has the function of stabilizing the oil-conducting cotton 2 and is also conducive to accelerating the guiding of the tobacco oil in the oil cup to the heating element 1, thereby accelerating the oil guiding rate.

[0026] Of course, in another embodiment, see Figure 4 and Figure 5, the atomizing tube 3 has a slot 32 and three openings 31, and the three openings 31 and one slot 32 are evenly distributed along the circumference of the atomizing tube 3. Three openings 31 are provided in the atomizing tube 3, and the lower part of each opening 31 is configured as an oil inlet hole 311, and the upper part is configured as a pressure relief hole 312. The end of the pressure relief hole 312 farthest from the oil-conducting cotton 2 is the highest point of the pressure relief hole 312, and the distance between the highest point of the pressure relief hole 312 and the end of the oil-conducting cotton 2 closest to it is H, H≧0.5cm, so that the pressure relief hole 312 can be effectively formed to facilitate exhaust.

[0027] The oil conduction speed of the atomizer core assembly was tested according to the scheme mentioned in the patent "CN202210881039.3-A method for testing the oil conduction speed of the atomizer core". There are 3 groups of atomizer core assemblies with pressure relief holes and 3 groups of atomizer core assemblies without pressure relief holes. The experimental test samples are the same except whether they have pressure relief holes. The initial oil conduction speeds of the atomizer cores are measured respectively, and the data are as follows:

[0028] serial number Initial weight / g Weight after 10S / g Mass increase / g 1# 0.596 0.717 0.121 2# 0.595 0.683 0.088 3# 0.595 0.689 0.094

[0029] Table 1 Oil guide speed of atomizer core with pressure relief hole

[0030] serial number Initial weight / g Weight after 10S / g Mass increase / g 1# 0.615 0.686 0.071 2# 0.612 0.688 0.076 3# 0.611 0.691 0.08

[0031] Table 2 Oil guide speed of atomizer core without pressure relief hole

[0032] By comparing the two sets of data, it can be clearly seen that the initial oil guide speed of the atomizer tube with a pressure relief hole is increased by 33.6% compared with that without a pressure relief hole.

[0033] The above are only specific embodiments of the present invention, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
