Description

CROSS REFERENCE TO RELATED APPLICATION(S)

This application claims priority to Chinese Patent Application No. 201922061877.2, entitled “Atomization assembly and electronic cigarette” and submitted to China National Intellectual Property Administration on Nov. 26, 2019, the entire contents of which are incorporated herein by reference.

The heating element includes a heating portion configured for generating heat and a conductive pin portion, wherein the heating portion is configured for heating the e-liquid transmitted by the porous body to form an aerosol for inhalation.
During the process of smoking of electronic cigarette, as the e-liquid in the e-liquid storage cavity is continuously consumed on the porous body, a situation of negative pressure will occur in the closed liquid storage cavity; in order to offset the negative pressure to reach an air pressure balance, the external atmospheric pressure will continuously supplement air into the liquid storage cavity through the porous body, which is the phenomenon of liquid bubbling we have ever seen. Since the liquid guide for atomization and the air pressure compensation both act at one same position of the porous body, in addition, the direction of liquid guide is downward while the direction of air pressure compensation is upward, namely, the liquid and the air flow in opposite directions, the air pressure compensation will influence the supply of liquid guide and leads to the occurrence of burnt smell.

DETAILED DESCRIPTION

For a better understanding, the present disclosure is described below in further detail in conjunction with accompanying drawings and specific embodiments.

Embodiment 1

With reference to FIG. 1 to FIG. 4 , the present disclosure provides an atomization assembly, including an e-liquid reservoir 1, a porous body 2, a heating element 3, an electrode 4 and a magnetic element 5, wherein the e-liquid reservoir 1 includes an aerosol channel a, an e-liquid storage cavity b used for storing an e-liquid, and an air inlet channel communicated with outside of the atomization assembly. The e-liquid reservoir 1 includes an e-liquid storage sleeve 11, a sealing seat 12, a fixing seat 13 and a blocking seat 14; the e-liquid storage sleeve 11 includes a sleeve body portion 111 and a tube body portion 112, the tube body portion 112 is accommodated in the sleeve body portion 111, an inner space of the tube body portion 112 forms the aerosol channel a, the e-liquid storage cavity b is formed between the tube body portion 112 and the sleeve body portion 111, and the e-liquid storage cavity b is arranged surrounding the aerosol channel a.
The sealing seat 12 is accommodated in the e-liquid storage sleeve 11 and is sleeved on the porous body 2, and a peripheral surface of the sealing seat 12 presses against the e-liquid storage sleeve 11 elastically to seal the cavity opening of the e-liquid storage cavity b. The sealing seat 12 includes a first perforation 121, a second perforation 122 and a third perforation 123; both of the first perforation 121 and the third perforation 123 are communicated with the e-liquid storage cavity b. The second perforation 122 is located between the first perforation 121 and the third perforation 123 and is spaced from the first perforation 121 and the third perforation 123. A first end of the tube body portion 112 is connected to the sleeve body portion 111, and a second end of the tube body portion 112 is inserted into the second perforation 122.
The fixing seat 13 is installed on an end part of the e-liquid storage sleeve 11 and located on an end surface of the e-liquid storage sleeve 11. The fixing seat 13 and the e-liquid storage sleeve 11 are in interference fit or buckled connection, etc., and no concrete limitation is made here. In the present embodiment, the fixing seat 13 and the e-liquid storage sleeve 11 are in interference fit, a peripheral surface of the fixing seat 13 is further sleeved with a sealing ring 6, and the sealing ring 6 presses against an inner wall surface of the e-liquid storage sleeve 11 elastically. The fixing seat 13 presses against the sealing seat 12, the fixing seat 13 includes the first e-liquid holding tank 131, and the first e-liquid holding tank 131 faces the porous body 2, thereby being able to collect the e-liquid leaking from the porous body 2 or a condensed e-liquid formed on the aerosol channel a.
The fixing seat 13 includes an air inlet 132, the air inlet 132 passes through a bottom wall of the first e-liquid holding tank 131, and an air exit of the air inlet 132 is higher than the bottom wall of the first e-liquid holding tank 131, thereby being able to prevent the e-liquid inside the first e-liquid holding tank 131 flowing out from the air inlet 132 and better avoiding leakage of e-liquid. The blocking seat 14 is located between the porous body 2 and the fixing seat 13 and presses against the porous body 2, so that the porous body 2 is more firmly fixed. The blocking seat 14 includes an air groove 141, a bottom wall of the air groove 141 includes an air through-hole 142, and the air through-hole 142 is communicated with the first e-liquid holding tank 131 and the air groove 141. In the present embodiment, the blocking seat 14 is made of a silicone material, which can better seal the porous body 2. The air inlet 132 serves as the air inlet channel. It is understandable that the structure of the e-liquid reservoir 1 may be arranged as needed, as long as it can be configured for storing an e-liquid, and no concrete limitation is made for the structure here.
The porous body 2 is used for adsorbing the e-liquid in the e-liquid storage cavity b, the porous body 2 includes an e-liquid guide wall 21 and an air inlet wall 22, and the e-liquid guide wall 21 is configured for guiding the e-liquid in the e-liquid storage cavity b to the heating element 3 to atomize. The air in the air inlet channel can flow into the e-liquid storage cavity b through the air inlet wall 22, which means the porous body 2 does not require an extra air hole for air admission and only needs the micropores of the material of the air inlet wall 22 itself for air admission. When the atmospheric pressure inside the e-liquid storage cavity b is smaller than the atmospheric pressure outside the atomization assembly, the air outside the atomization assembly passes through the air inlet channel and enters the e-liquid storage cavity b from the air inlet wall 22, so that the atmospheric pressure inside the e-liquid storage cavity b is equal to or tends to be equal to the atmospheric pressure outside the atomization assembly.
It is understandable that the speed of the air to flow into the e-liquid storage cavity b is determined by the size of the micropore of the material of the air inlet wall 22 itself and the difference in atmospheric pressure between inside of the e-liquid storage cavity b and outside of the atomization assembly. The blocking seat 14 is configured for guiding an airflow entering from the air inlet 132 onto the e-liquid atomization surface 21. Arrows shown in FIG. 2 indicate the flow direction of air during the operation of the atomization assembly.
The porous body 2 may be a porous ceramic body or a fibrous body, etc., and no concrete limitation is made here. In the present embodiment, the porous body 2 includes a first recess 23, a second recess 24 and a blocking wall 25 located between the first recess 23 and the second recess 24; the first recess 23 corresponds to the first perforation 121 in position, and the second recess 24 corresponds to the third perforation 123 in position. Both of the first recess 23 and the second recess 24 are communicated with the e-liquid storage cavity b; an inner wall surface of the first recess 23 and an inner wall surface of the second recess 24 form an e-liquid contact surface p1, and the porous body 2 adsorbs the e-liquid in the e-liquid storage cavity b by means of the e-liquid contact surface p1.
It is understandable that the e-liquid contact surface p1 refers to a surface of the porous body 2 which is configured for absorbing the e-liquid in the e-liquid storage cavity b by contacting the e-liquid flowing downward from the e-liquid storage cavity b; the e-liquid in the e-liquid storage cavity b enters the porous body 2 through this surface; the e-liquid contact surface p1 may be constructed by a plane or a curved surface, and there may be one or more planes or curved surfaces.
A bottom wall of the first recess 23 forms the e-liquid guide wall 21 of which a bottom surface forms the e-liquid atomization surface P2, and the porous body 3 provides, through the e-liquid atomization surface P2, the absorbed e-liquid to the heating element 3 to atomize. A bottom wall of the second recess 24 forms an air inlet wall 22 of which a bottom surface forms the air inlet surface p3, and the air inlet surface p3 is used for allowing air to flow into the porous body 2 and flow into the e-liquid storage cavity b by means of the porous body 2; the distance between the air inlet surface p3 and the e-liquid contact surface p1 is smaller than the distance between the e-liquid atomization surface p2 and the e-liquid contact surface p1, which means the air inlet wall 22 has a smaller thickness than the e-liquid guide wall 21; therefore, external air may flow into the e-liquid storage cavity b relatively smoothly.
Specifically, a surface of the porous body 2 away from the e-liquid storage cavity b is a bottom surface p4 for the heating element 3 to attach onto, both of the e-liquid atomization surface p2 and the air inlet surface p3 are located within the bottom surface p4, and the bottom surface p4 is a plane, that is to say, the e-liquid atomization surface p2 and the air inlet surface p3 are located within one same plane, which facilitates manufacturing. It is understandable that the heating element 3 may be completely located within the e-liquid atomization surface p2, also may be extended onto the air inlet surface p3, and no concrete limitation is made here. The blocking wall 25 includes an air hole 26 which is communicated with the aerosol channel a, the e-liquid guide wall 21 and the air inlet wall 22 are located at two opposite sides of the position of the air hole 26 respectively, making the overall ventilation relatively smoother. Since the bottom wall of the first recess 23 forms the e-liquid guide wall 21, a side wall of the first recess 23 can also provide e-liquid for the e-liquid guide wall 21, thereby better ensuring sufficient supply of e-liquid.
Between the bottom wall of the air groove 141 and the porous body 2 is formed an atomization channel c which is configured for allowing an aerosol formed by atomization of e-liquid to flow through; the atomization channel c is communicated with the air inlet 132, the air hole 26 and the aerosol channel a, so as to discharge the aerosol formed by atomization of e-liquid to the outside of the atomization assembly. Both of the e-liquid atomization surface p2 and the air inlet surface p3 are located inside the atomization channel c, which not only facilitates the discharge of aerosol to the outside of the atomization assembly, but also minimizes, during the process of smoking, the difference in atmospheric pressure between insides of the e-liquid storage cavity b and the atomization channel c, so that the e-liquid may easily flow onto the e-liquid atomization surface p2. During smoking, external air flows into the atomization channel c from the air inlet 132, and then, together with the aerosol inside the atomization channel c, passes through the air hole 26 and the aerosol channel a to be discharged to the outside of the atomization assembly.
At least part of the heating element 3 is in contact with the e-liquid guide wall 21 so as to atomize the e-liquid on the e-liquid guide wall 21, which means the heating element 3 may be embedded into the e-liquid guide wall 21 and partially extended onto the e-liquid atomization surface p2, or the heating element 3 is an electric heating circuit printed onto the e-liquid atomization surface p2, or one end of the heating element 3 is located on the e-liquid atomization surface p2 and the other end is located on the air inlet surface p3. Therefore, the heating element 3 is completely or at least in part in contact with the e-liquid guide wall 21, and no concrete limitation is made here.
In the present embodiment, the heating element 3 includes a heating section 31, an extending section 32, a first electrical connection portion 33 and a second electrical connection portion 34; the heating section 31 is attached onto the e-liquid guide wall 21 and is connected to the first electrical connection portion 33; the heating section 31 is located within the e-liquid atomization surface p2, which means the heating section 31 is arranged extending on the e-liquid atomization surface p2, thereby being able to fully atomize the e-liquid on the e-liquid atomization surface p2. A first end of the extending section 32 is connected to a first end of the heating section 31, the first electrical connection portion 33 is connected to a second end of the heating section 31, and a second end of the extending section 32 is connected to the second electrical connection portion 34; the extending section 32 has a greater cross-sectional area than the heating section 31. The extending section 32 is arranged deviating from the e-liquid atomization surface p2 and is attached onto the porous body 2, thereby being able to avoid, during operation, dry burning occurring at an area of the porous body 2 where the extending section 32 is located.
Preferably, at least part of the extending section 32 is attached onto the air inlet surface p3, and a contact area between the extending section 32 and the porous body 2 is greater than a contact area between the heating section 31 and the porous body 2, thereby being able to reduce the likelihood of the e-liquid dropping from the extending section 32. It is understandable that the heating element 3 may be a metal wire, also may be an electric heating circuit printed onto the porous body 2, and no concrete limitation is made here, as long as it can be electrified to generate heat. In addition, in some embodiments, the heating element 3 is completely located on the e-liquid atomization surface p2, and the porous body 2 may not be provided with the first recess 23. Of course, the porous body 2 may not be provided with the second recess 24 either, as long as the distance between the air inlet surface p3 and the e-liquid contact surface p1 is smaller than the distance between the e-liquid atomization surface p2 and the e-liquid contact surface p1.
The electrode 4 is fixed on the fixing seat 13; one end of the electrode 4 presses against the heating element 3, and the other end of the electrode 4 is electrically connected to the battery assembly. In the present embodiment, there are two electrodes 4; one electrode presses against the first electrical connection portion 33 and the other electrode presses against the second electrical connection portion 24. The magnetic element 5 is fixed on the fixing seat 13 for magnetic connection with the battery assembly, so that the connection is more secure.
The present disclosure further provides an electronic cigarette, including an atomization assembly and a battery assembly configured for supplying power to the atomization assembly, wherein the atomization assembly is the one described above, having the same technical effect. The battery assembly is of an available technology, and no concrete limitation is made for the structure here.
Due to the fact that the porous body 2 includes the e-liquid atomization surface p2 and the air inlet surface p3 that are separately arranged, the distance between the air inlet surface p3 and the e-liquid contact surface p1 is smaller than the distance between the e-liquid atomization surface p2 and the e-liquid contact surface p1, and air can flow into the e-liquid storage cavity b through the air inlet surface p3, thus, the atmospheric pressure inside the e-liquid storage cavity b is equal to or not so different from the atmospheric pressure outside the atomization assembly, the e-liquid inside the e-liquid storage cavity b can smoothly flow onto the e-liquid guide wall 21, with sufficient supply of e-liquid. When the heating element 3 generates heat, the e-liquid guide wall 21 can provide sufficient e-liquid, and therefore burnt smell can be avoided.

Specifically, the tank opening of the second e-liquid holding tank 143 is arranged facing the air inlet wall 22, to better collect the e-liquid dropping or leaking from the air inlet wall 22.

With reference to FIG. 6 , the present embodiment is similar to Embodiment 1 in structure, with the main difference lying in that the blocking seat 14 includes a second e-liquid holding tank 143, of which a tank opening is arranged facing the porous body 2. Specifically, the tank opening of the second e-liquid holding tank 143 is arranged facing the entire bottom surface of the porous body 2, to better collect the e-liquid dropping or leaking from the porous body 2. In the present embodiment, an air inlet groove is located on a side wall of the blocking seat 14. According to the present embodiment, the second e-liquid holding tank 143 has a larger space and can contain more e-liquid.
