Description

Technical Field

[0001] The present application relates to the technical field of electronic atomization, and in particular to an atomizer and an electronic atomization device. Background Art

[0002] As a substitute for traditional cigarettes, electronic atomization devices usually include a power supply device and an atomizer. The power supply device is used to supply power to the atomizer. The atomizer usually includes a hollow shell and an atomizer assembly arranged inside the shell. The shell is also provided with an atomization channel and a liquid storage chamber for supplying atomized liquid to the atomizer assembly. The bottom of the liquid storage chamber has an oil outlet for assembling the atomizer assembly. The atomizer assembly usually includes an oil guide body and a heating body. The oil guide body is used to guide the atomized liquid supplied by the liquid storage chamber to the heating body. The heating body is used to heat the atomized liquid supplied by the atomizer storage chamber to form an inhalable aerosol leading to the atomization channel.

[0003] In order to quickly supply liquid and ensure that it has a certain strength, the traditional oil guide body is usually designed with a groove for guiding liquid on its liquid suction surface (the oil guide body has a liquid suction surface facing the liquid storage chamber and an atomizing surface arranged opposite to the liquid suction surface). However, when the atomized liquid is relatively viscous, the bubbles generated by ventilation are easily stuck in the above-mentioned grooves. The bubbles stuck in the above-mentioned grooves are difficult to float to the liquid surface of the atomized liquid in the liquid storage chamber, thereby causing the liquid suction surface of the oil guide body to be blocked, and then causing the heating element to dry burn and produce a burnt smell due to insufficient liquid supply. In addition, in order to improve the sealing performance, a sealing structure that at least partially abuts against the edge of the liquid suction surface of the heating element is usually provided. At the same time, the bottom of the liquid storage chamber is used to assemble the liquid suction surface of the corresponding heating element in the oil outlet hole of the atomizing assembly. The above-mentioned sealing structure and step further increase the distance from the inner bottom wall of the above-mentioned groove to the inner bottom wall of the liquid storage chamber, so that the bubbles generated by ventilation are more likely to be stuck in the above-mentioned groove.

[0035] Reference Figures 1 to 9 , an atomizer according to an embodiment of the present application includes a housing 100 and an atomization assembly.

[0036] Specifically, the housing 100 is provided with a liquid storage chamber 110 for storing atomized liquid, the housing 100 has a barrier wall 120 located at the bottom of the liquid storage chamber 110, the barrier wall 120 has a first surface a constituting the inner bottom wall of the liquid storage chamber 110 and a second surface b opposite to the first surface a, an oil outlet hole 121 is provided on the barrier wall 120 that penetrates the first surface a and the second surface b in the longitudinal direction, the atomization assembly includes an oil guide body 200 and a heating body 300, the oil guide body 200 has a liquid suction end and an atomization end that are arranged oppositely, and the heating body 300 is at least partially arranged at the guide body 200. The atomizing end of the oil body 200, the oil guide body 200 is at least partially accommodated in the oil outlet hole 121, and the liquid suction end of the oil guide body 200 has a liquid suction surface c for contacting the atomized liquid in the liquid storage chamber 110, and the liquid suction surface c can guide the contacted atomized liquid to the atomizing end of the oil guide body 200, so that the atomized liquid can be heated and atomized by the heating element 300 to form an inhalable aerosol, and the height of the liquid suction surface c along the longitudinal direction is lower than the first surface a of the barrier wall 120, wherein the maximum distance between the liquid suction end of the oil guide body 200 and the first surface a of the barrier wall 120 is less than 0.5 mm. It should be noted that the above-mentioned longitudinal direction is the X direction in the accompanying drawings.

[0037] The inventor of the present application discovered during the research and development process that there is usually an area not filled by the oil guide body 200 on one side of the oil outlet hole 121 near the liquid storage chamber 110 for assembling the atomization assembly on the shell 100 of the traditional atomizer, and the area will be filled with the atomized liquid stored in the liquid storage chamber 110 (for the convenience of expression, the area is hereinafter referred to as "the area filled with the atomized liquid in the oil outlet hole 121"). Since the area filled with the atomized liquid in the oil outlet hole 121 is usually narrow, when the atomized liquid is relatively viscous, the area filled with the atomized liquid in the oil outlet hole 121 is not conducive to the passage of bubbles generated by ventilation, so that during the use of the atomizer, the bubbles generated by ventilation are easily stuck in the oil outlet hole 121, thereby preventing the atomized liquid in the liquid storage chamber 110 from entering the oil outlet hole 121, reducing the amount of liquid supplied from the liquid storage chamber 110 to the liquid suction end of the oil guide body 200, thereby causing the heating element 300 to dry burn and produce a burnt smell due to insufficient liquid supply, thereby affecting the user's experience. In order to solve the above-mentioned problems, the inventors of the present application proposed the atomizer of the above-mentioned embodiment of the present application. Since the height of the liquid absorption surface c along the longitudinal direction is adjusted, and at the same time, the liquid absorption end of the oil guide body 200 is not provided with a groove structure for liquid conduction, and in addition, the oil outlet hole 121 is not provided with a step structure for cooperating with the liquid absorption end of the oil guide body 200 to limit the position, therefore, it is helpful to reduce the area filled with atomized liquid in the oil outlet hole 121, that is, it can reduce the area in the oil outlet hole 121 where bubbles are easily stuck, thereby helping to reduce the situation where bubbles generated by ventilation are stuck in the oil outlet hole 121, and further helping to reduce the situation where the heating element 300 is dry-burned and produces a burnt smell due to insufficient liquid supply.

[0038] It should be noted that, in some of the embodiments, in order to ensure that the oil-conducting body 200 has a certain structural strength, the oil-conducting body 200 is made of a hard porous material. Specifically, the oil-conducting body 200 can be made of porous ceramics or porous glass, which is not limited here.

[0039] It should be noted that, in some other embodiments, the height of the liquid absorption surface c in the longitudinal direction may also be flush with the first surface a of the barrier wall 120, that is, the maximum distance between the liquid absorption end of the oil guide body 200 and the first surface a of the barrier wall 120 is 0 mm, which can also reduce the area in the oil outlet hole 121 where bubbles are easily stuck, thereby preventing bubbles generated by ventilation from being stuck in the oil outlet hole 121, which is not limited here.

[0040] It should be noted that, in some other embodiments, at least part of the liquid absorption surface c is higher in the longitudinal direction than the first surface a of the barrier wall 120, which can also reduce the area in the oil outlet hole 121 where bubbles are easily stuck, thereby preventing bubbles generated by ventilation from getting stuck in the oil outlet hole 121, which is not limited here.

It should be emphasized that the liquid absorbing surface c is formed on the protrusion 210, that is, the protrusion 210 is not a protruding structure protruding from the liquid absorbing surface c.

[0043] Reference Figure 4 In some embodiments, the protrusion 210 is wedge-shaped, so that two inclined liquid absorption surfaces c are formed on the protrusion 210, so that the bubbles generated by ventilation can be guided into the liquid storage chamber 110 by the inclined liquid absorption surfaces c, thereby preventing the bubbles generated by ventilation from being stuck in the oil outlet hole 121.

[0044] It should be noted that in some other embodiments, the protrusion 210 may also be in a pyramidal shape, such as a triangular pyramid, a quadrangular pyramid, etc., so that the liquid suction end of the oil guide body 200 has at least three inclined liquid suction surfaces c, which is not limited here.

[0047] It should be noted that, in some of the embodiments, a limiting structure is provided between the oil guide body 200 and the housing 100. Specifically, the limiting structure is disposed between the atomizing end of the oil guide body 200 and the housing 100, and will not increase the area filled with the atomized liquid in the oil outlet hole 121, that is, will not increase the area in the oil outlet hole 121 where bubbles are easily stuck, thereby helping to prevent bubbles generated during ventilation from being stuck in the oil outlet hole 121.

The top of the shell 100 has an opening connected to the liquid storage chamber 110, and a first sealing member 400 is provided at the top opening of the shell 100.

[0051] Reference Figures 6 to 9 In some other embodiments, the limiting structure includes an annular limiting portion 220 disposed at the atomizing end of the oil guide body 200, the outer diameter of the annular limiting portion 220 is greater than the aperture of the oil outlet hole 121, and the annular limiting portion 220 is located outside the liquid storage chamber 110 and is used to cooperate with the blocking wall 120 to limit the oil guide body 200, so as to limit the oil guide body 200 from the side of the oil outlet hole 121 close to the liquid storage chamber 110 to leave the oil outlet hole 121. During assembly, the atomizing assembly is assembled from the outside of the liquid storage chamber 110 to the oil outlet hole 121 in the longitudinal direction. The annular limiting portion 220 disposed at the atomizing end of the oil guide body 200 cooperates with the blocking wall 120 to limit the area filled with atomized liquid in the oil outlet hole 121, that is, the area in the oil outlet hole 121 where bubbles are easily stuck will not be increased, which is conducive to preventing bubbles generated during ventilation from being stuck in the oil outlet hole 121.
