Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an electronic atomizer. Background Technology

[0002] Some electronic atomizers include a supply chamber that provides the atomizing matrix to the atomizing reservoir. The reservoir houses an atomizing component, which is surrounded by a wicking cotton. This cotton absorbs the atomizing matrix from the supply chamber and transfers it to the atomizing component, which then atomizes the matrix. In some supply chambers, a porous wicking medium is used to control the flow rate of the atomizing matrix to the reservoir, preventing leakage due to oversaturation of the wicking cotton. However, existing porous wicking media have poor contact with the wicking cotton, resulting in poor fluid conduction between them. Utility Model Content

[0003] The main objective of this application is to provide an electronic atomizer that solves the technical problem of poor liquid conduction by existing porous liquid-conducting media and liquid-conducting cotton.

[0017] Optionally, the liquid storage tank includes an upper shell, a sealing seat, and a base. The sealing seat is disposed between the upper shell and the base and seals the upper shell and the base. The liquid inlet cylinder is formed in the base. The air return hole is opened in the upper shell. The sealing seat has an air-avoiding opening corresponding to the liquid inlet cylinder. The atomizing component is disposed in the upper shell and its bottom end is sealed and inserted into the sealing seat.

[0018] The first liquid guiding medium is disposed inside the upper shell. A return air cavity is formed between the top surface of the first liquid guiding medium and the top wall of the upper shell. A vertically penetrating return air channel is formed in the first liquid guiding medium, and the cross-sectional area of ​​the return air channel is 0.3-2 mm. 2 The bottom surface of the first liquid guiding medium is connected to the sealing seat, the top surface of the sealing seat is recessed downward to form a return air channel, the top surface of the liquid inlet cylinder is hollowed out downward to form a return air port, the outside atmosphere, the return air hole, the return air chamber, the return air channel, the return air port, the return air gap and the liquid supply chamber are connected in sequence, and the return air flow route is formed by the return air chamber, the return air channel, the return air channel and the return air port.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0038] This application discloses an electronic atomizer, which includes a liquid storage chamber, a first liquid guiding medium, a second liquid guiding medium, an atomizing component, and a supply chamber. An inlet cylinder is formed on one side of the liquid storage chamber. The first liquid guiding medium is disposed within the liquid storage chamber. The second liquid guiding medium is also disposed within the liquid storage chamber, with one end of the second liquid guiding medium disposed within and connected to the inlet cylinder, and the other end of the second liquid guiding medium sleeved within the first liquid guiding medium. The interference fit between the second and first liquid guiding media is 0–1.5 mm. The atomizing component is disposed within the liquid storage chamber and sleeved within the first liquid guiding medium, and is connected to the first liquid guiding medium. The supply chamber is sealed and connected to the inlet cylinder, and is connected to the second liquid guiding medium.

[0039] In the electronic atomizer of this application, the second liquid guiding medium is sleeved within the first liquid guiding medium, with an interference fit of 0–1.5 mm. This sleeved assembly method, compared to the traditional end-face contact assembly method, increases the contact area between the second and first liquid guiding media, thereby increasing the liquid guiding speed and preventing the atomizing core of the atomizing component from dry burning. It also reduces the risk of leakage due to localized accumulation of the atomizing matrix. When the interference fit is greater than 0, the pre-tightening force of the interference fit effectively prevents the second and first liquid guiding media from momentarily separating, thus avoiding sudden interruption of liquid guiding. The atomizing matrix can penetrate from the second liquid guiding medium to the first liquid guiding medium at a relatively stable rate, resulting in highly uniform vapor concentration and fineness, and a more ideal flavor.

[0040] Please combine Figures 1 to 7 The following will mainly describe the specific structure of the electronic atomizer 10.

[0041] The electronic atomizer 10 of this application includes a liquid storage chamber 100. The liquid storage chamber 100 includes an upper shell 110, a sealing seat 120, and a base 130. The bottom end of the upper shell 110 is open. The sealing seat 120 is disposed between the upper shell 110 and the base 130. The sealing seat 120 is made of an elastic material. The upper shell 110 and the base 130 are both made of rigid materials. The sealing seat 120 is interference-sealed to connect the upper shell 110 and the base 130.

[0042] The top wall of the liquid storage tank 100 is provided with a vent 111 that connects to the outside atmosphere. The vent 111 is located on the top wall of the upper shell 110. The number of vents 111 can be at least one, and is not specifically limited. Preferably, there are two vents 111. The top inner wall of the upper shell 110 extends downward to form a first limiting rib 112 and a second limiting rib 113.

[0043] The top surface of the sealing seat 120 is recessed downward to form a return air passage 121. The return air passage 121 includes a first passage 122, a second passage 123 and a third passage 124. The second passage 123 is arc-shaped and the middle part of the second passage 123 is connected to the third passage 124. The first passage 122 is not connected to the second passage 123 / third passage 124.

[0044] A liquid inlet cylinder 131 is formed on one side of the liquid storage tank 100, and the liquid inlet cylinder 131 is formed at the bottom end of the base 130. The sealing seat 120 has an air vent 125 corresponding to the liquid inlet cylinder 131, such as... Figure 7 As shown, one end of the first channel 122 is connected to the air vent 125, and the other end of the first channel 122 passes through the sealing seat 120. Both ends of the second channel 123 are connected to the air vent 125, and the end of the third channel 124 away from the second channel 123 passes through the sealing seat 120.

[0045] The liquid inlet cylinder 131 includes a first section 132 and a second section 133 connected to each other. The diameter of the first section 132 is smaller than the diameter of the second section 133, and the first section 132 is closer to the upper shell 110 than the second section 133. Multiple spikes 134 are formed extending from the inner wall of the liquid inlet cylinder 131. These spikes 134 are spaced apart circumferentially along the liquid inlet cylinder 131 and are formed inside the top of the liquid inlet cylinder 131, i.e., inside the top of the first section 132. A return air port 136 is formed by hollowing out the top surface of the liquid inlet cylinder 131 (i.e., the top surface of the first section 132). The return air port 136 includes a first port 137, a second port 138, and a third port 139 spaced apart, arranged circumferentially along the first section 132. One end of the first channel 122 is opposite to and connected to the first opening 137. The two ends of the second channel 123 are opposite to and connected to the second opening 138 and the third opening 139, respectively.

[0046] The electronic atomizer 10 of this application includes a first liquid guiding medium 200, which is disposed within a liquid storage chamber 100. The first liquid guiding medium 200 is capable of drawing in and transferring the atomizing matrix. A return airflow path is formed between the first liquid guiding medium 200 and the wall of the liquid storage chamber 100, and the top end of the return airflow path (when the electronic atomizer 10 is upright) is connected to a return air port 111.

[0047] The first liquid guiding medium 200 is specifically disposed inside the upper shell 110. The first limiting rib 112 abuts against the top surface of the first liquid guiding medium 200, and the bottom surface of the first liquid guiding medium 200 is connected to the sealing seat 120. A return air cavity 114 is formed between the top surface of the first liquid guiding medium 200 and the top wall of the upper shell 110, and the return air cavity 114 is connected to the return air hole 111. The first limiting rib 112 cooperates with the sealing seat 120 to fix the first liquid guiding medium 200. The first limiting rib 112 is used to assist the top surface of the first liquid guiding medium 200 and the top inner wall of the upper shell 110 in forming the aforementioned return air cavity 114. The number of first limiting ribs 112 can be multiple, thereby improving the installation effect of the first liquid guiding medium 200 in the liquid storage tank 100.

[0048] The first liquid guiding medium 200 is hollowed out to form a vertically penetrating return air channel 220 (when the electronic atomizer 10 is upright), the cross-sectional area of ​​the return air channel 220 is 0.3-2 mm. 2 The optimal cross-sectional area of ​​the return air duct 220 is 0.4–0.6 mm². 2 The return air channel 220 connects the return air chamber 114 and the return air passage 121. The aforementioned return air passage is formed by the return air chamber 114, the return air channel 220, the return air passage 121, and the return air port 136. The return air channel 220 is formed at the edge of the first liquid guiding medium 200. The return air channel 220 penetrates the first liquid guiding medium 200 in the horizontal direction (when the electronic atomizer 10 is upright). Therefore, the return air channel 220 is not easily sealed by the atomizing matrix liquid, and can have a better air circulation effect. The return air channel 220 includes a first channel 221 and a second channel 222, which are respectively formed on both sides of the first liquid guiding medium 200. The top of the first groove 221 is connected to the return air chamber 114, and the bottom of the first groove 221 is connected to the end of the first channel 122 away from the first opening 137. The top of the second groove 222 is connected to the return air chamber 114, and the bottom of the second groove is connected to the end of the third channel away from the second channel 123.

[0049] The electronic atomizer 10 of this application includes a second liquid guiding medium 300, which is disposed within a liquid storage chamber 100. The second liquid guiding medium 300 can draw in and transfer the atomizing matrix. One end of the second liquid guiding medium 300 is disposed within and connected to the liquid inlet cylinder 131, and the other end of the second liquid guiding medium 300 is sleeved within a first liquid guiding medium 200. The first liquid guiding medium 200 is hollowed out to form a through hole 210, and the second liquid guiding medium 300 is sleeved within the through hole 210. The interference fit between the second liquid guiding medium 300 and the first liquid guiding medium 200 (i.e., the through hole 210) can be 0 to 1.5 mm. The second liquid guiding medium 300 and the first liquid guiding medium 200 can be interference-fitted, that is, the interference fit between the two is greater than 0. Furthermore, the interference between the second liquid guiding medium 300 and the first liquid guiding medium 200 may include, but is not limited to, 0.5-1.5 mm, 0.5-1.0 mm, 0.3-1.2 mm, 0.8-1.1 mm, 0.4-0.7 mm, or 1.2-1.5 mm.

[0050] The second liquid guiding medium 300 is specifically connected to multiple clips 134 inside the liquid inlet cylinder 131. Through the connection of these clips 134, the second liquid guiding medium 300 is less likely to fall off due to gravity. When the second liquid guiding medium 300 is interference-fitted with the first liquid guiding medium 200 (interference greater than 0), the second liquid guiding medium 300 is even less likely to fall off due to gravity. A return air gap 135 is formed between the second liquid guiding medium 300 and the liquid inlet cylinder 131, and the return air gap 135 connects to the return air port 136. The first groove 221 is closer to the second liquid guiding medium 300 than the second groove 222.

[0051] The liquid guiding capacity of the second liquid guiding medium 300 can be greater than or equal to that of the first liquid guiding medium 200. The length direction of the second liquid guiding medium 300 can be parallel to the vertical direction (when the electronic atomizer 10 is upright). The second liquid guiding medium 300 can penetrate (specifically, it can penetrate in the vertical direction) the first liquid guiding medium 200, that is, the through hole 210 of the first liquid guiding medium 200 is penetrating in the vertical direction. The return air hole 111 of the upper shell 110 is set close to the second liquid guiding medium 300, thereby improving the return air effect of the second liquid guiding medium 300. The second limiting rib 113 formed in the upper shell 110 is set close to the return air hole 111 (because the return air hole 111 is set close to the second liquid guiding medium 300), and the second limiting rib 113 abuts against the top surface of the second liquid guiding medium 300. The second limiting rib 113 is used to cooperate with the liquid inlet cylinder 131 (specifically, multiple spurs 134) to fix the second liquid guiding medium 300.

[0052] The electronic atomizer 10 of this application includes a guide tube 600, which can be made of a rigid material (such as metal or plastic). The guide tube 600 is sleeved inside the liquid inlet tube 131 and located below a plurality of clips 134. The bottom end of the second liquid guiding medium 300 is located inside the guide tube 600 and spaced apart from it, meaning there is a fitting gap between the guide tube 600 and the second liquid guiding medium 300. This fitting gap can be formed by creating a groove in the second liquid guiding medium 300 to fit with the guide tube 600. The groove is not limited to square grooves, V-shaped grooves, etc., and can also be formed by fitting with a regular contour. The cross-sectional area of ​​the gap between the guide tube 600 and the second liquid guiding medium 300 is 0.1–30 mm. 2 The inner cavity of the guide cylinder 600 (i.e., the aforementioned fitting clearance) is connected to the return gas clearance 135. The guide cylinder 600 is connected to the inner wall of the first section 132, and the guide cylinder 600 and the first section 132 can be interference-fitted, bonded, or screwed together. The guide cylinder 600 can protect the second liquid guiding medium 300.

[0053] The electronic atomizer 10 of this application includes an atomizing component 400, which is disposed within a liquid storage chamber 100 and sleeved within a first liquid guiding medium 200, and is connected to the first liquid guiding medium 200. The atomizing component 400 is used to draw atomizing matrix from the first liquid guiding medium 200 and atomize the atomizing matrix. The atomizing component 400 is specifically disposed within an upper shell 110 and its bottom end is sealed and inserted into a sealing seat 120. The axial direction of the atomizing component 400 is parallel to the vertical direction (when the electronic atomizer 10 is upright). The atomizing component 400 is closer to the center of the first liquid guiding medium 200 than the second liquid guiding medium 300, thereby providing more uniform liquid supply in the circumferential direction of the atomizing component 400, and the atomizing core of the atomizing component 400 is less prone to local dry burning. The arc-shaped second channel 123 formed by the sealing seat 120 surrounds the atomizing component 400. As a result, the return air channel 121 is set more evenly on the sealing seat 120, thus the exhaust effect is better.

[0054] The electronic atomizer 10 of this application includes a liquid supply chamber 500, which stores a large capacity of atomizing matrix. The liquid supply chamber 500 is detachably and sealed to the inlet cylinder 131, and the liquid supply chamber 500 is connected to a second liquid guiding medium 300. Through the liquid guiding of the second liquid guiding medium 300 and the first liquid guiding medium 200, the atomizing matrix in the liquid supply chamber 500 can be transferred to the atomizing assembly 400. The liquid supply chamber 500 includes a connecting cylinder 510, and a guide cylinder 600 is spaced apart from the second section 133 of the inlet cylinder 131. The connecting cylinder 510 of the liquid supply chamber 500 is detachably connected between the guide cylinder 600 and the inlet cylinder 131 (specifically the second section 133). The connecting cylinder 510 connects (interference fit, adhesive, or screw connection, etc.) the second section 133, and the guide cylinder 600 is used to guide the connecting cylinder 510 into the second section 133. The guide cylinder 600 and the outer wall of the connecting cylinder 510 can be spaced apart or slidably connected. The external atmosphere, return air hole 111, return air chamber 114, return air channel 220, return air passage 121, return air inlet 136, return air gap 135 and liquid supply chamber 500 are connected in sequence.

[0055] In this electronic atomizer 10, the second liquid guiding medium 300 is fitted inside the first liquid guiding medium 200, and the interference fit is 0-1.5mm. This fitting assembly method has many advantages over the traditional end-face contact assembly method: (1) Improves the stability and consistency of the atomized taste. The fitting eliminates interface transmission fluctuations through the large contact area and tight fit. The atomizing matrix can penetrate from the second liquid guiding medium 300 to the first liquid guiding medium 200 at a stable rate. The concentration and fineness of the atomized smoke are highly uniform, which improves the consistency of the user's inhalation taste. (2) Extends the service life of the atomizing core and the whole device. The improved liquid guiding speed and dry burning prevention directly reduce the losses of the atomizing core of the atomizing component 400 caused by local high temperature dry burning, such as the melting of the heating wire and carbonization of the liquid guiding medium, and extend the replacement cycle of the atomizing core; on the other hand, when the interference fit is greater than 0, the pre-tightening force of the interference fit can offset the contact gap caused by temperature changes or vibration during long-term use of the electronic atomizer 10, and prevent the liquid guiding medium from slowly detaching due to the increase in gap, thereby reducing the failure of the whole machine caused by liquid guiding failure and extending the overall service life of the product. (3) Enhance the reliability and safety of the usage scenario. In scenarios such as transportation bumps, daily shaking or drops by users, the tight connection of the fitting can effectively prevent the instantaneous detachment that is easy to occur in traditional end face contact, and avoid sudden dry burning caused by sudden interruption of liquid guiding; at the same time, uniform liquid guiding can reduce the risk of leakage caused by local atomizing matrix accumulation, and improve the safety and cleanliness of the product in portable usage scenarios. (4) Expand the range of atomizing matrix compatibility. The larger contact area and more stable liquid guiding channel provided by the socket can be adapted to atomizing matrices of different viscosities: for thick atomizing matrices, the larger contact area can reduce liquid guiding resistance and ensure smooth supply of atomizing matrices; for thin atomizing matrices, the tight fit can reduce the rapid penetration of atomizing matrices caused by excessive gaps (avoiding liquid accumulation in the atomizing core), enabling the product to be compatible with more types of atomizing matrices.

[0056] In this electronic atomizer 10, the outside atmosphere, return air port 111, return air chamber 114, return air channel 220, return air passage 121, return air inlet 136, return air gap 135, and liquid supply chamber 500 are connected in sequence. When the electronic atomizer 10 is upright, because the liquid supply chamber 500 is located below the liquid storage chamber 100, the liquid supply chamber 500 does not supply liquid, and the first liquid guiding medium 200 is in an unsaturated state due to user inhalation. Therefore, the return air path (including the return air chamber 114, return air channel 220, return air passage 121, and return air inlet 136) is not sealed by the atomizing matrix liquid and is in an open state. Both the liquid storage chamber 100 and the liquid supply chamber 500 are connected to the outside. The high pressure generated in the liquid storage chamber 100 due to the operation of the atomizing component 400 can be released to the outside atmosphere in a timely manner, so the liquid storage chamber 100 will not leak. When the electronic atomizer 10 is inverted, if the first liquid guiding medium 200 is in an unsaturated state, the return flow path is open, and the liquid supply chamber 500 supplies liquid to the first liquid storage chamber 100 through the second liquid guiding medium 300. As the liquid flows out, the air pressure in the liquid supply chamber 500 decreases. The opening of the return flow path allows the negative pressure in the liquid supply chamber 500 to be relieved in time, and the atomizing matrix can maintain smooth outflow. When the first liquid guiding medium 200 is saturated with liquid, the return flow path is sealed by the atomizing matrix, and the atomizing matrix in the liquid supply chamber 500 stops flowing out, so the liquid storage chamber 100 will not leak.

[0057] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
