An electronic cigarette vaporization apparatus 100 according to an embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.
Referring to FIG. 1 to FIG. 8, an electronic cigarette vaporization apparatus 100 according to an embodiment of the present disclosure includes a housing 10, a vaporization assembly 20, and a first seal member 30. An e-liquid storage tank 13 and the vaporization assembly 20 are arranged in the housing 10. The housing 10 is made of an elastic translucent material or an elastic transparent material. The e-liquid storage tank 13 is configured to store e-liquid in a liquid form, and the vaporization assembly 20 is mainly configured to vaporize liquid such as e-liquid to generate aerosol (vapor). An airflow channel 11 in communication with external air is provided on the housing 10. Air in the environment and the vapor generated by heating and vaporizing by the vaporization assembly 20 is introduced and exported through the airflow channel 11.
The vaporization assembly 20 mainly includes a porous body and a heating body, and the porous body uses a porous ceramic structure. The porous body has a liquid absorbing surface and a vaporization surface that are oppositely arranged, and the heating body is arranged on the vaporization surface of the porous body. The e-liquid is conducted to the vaporization surface through the liquid absorbing surface, is vaporized under the action of the heating body to form the vapor, and is exported from the vaporization surface. At least one vent channel 21 is provided on the porous body, an end of the vent channel 21 is in communication with the e-liquid storage tank 13, and an other end of the vent channel 21 is in communication with the external air.
The first seal member 30 is sleeved on the vaporization assembly 20, a first through hole 32 is provided on the first seal member 30, and the first through hole 32 is used for the first seal member 30 to conduct air and e-liquid. The first seal member 30 seals the vaporization assembly 20, to prevent the e-liquid in the e-liquid storage tank from flowing into the vaporization cavity from places other than the liquid absorbing surface. The first seal member 30 includes at least one seal portion 31 corresponding to the vent channel 21. The seal portion 31 opens and closes the vent channel 21 to allow the external air to enter the e-liquid storage tank 13 and prevent liquid in the e-liquid storage tank 13 from flowing out.
When a user inhales, a sensor in the electronic cigarette is triggered, which sends a signal to drive the vaporization assembly 20 to start heating. The liquid in the porous body is heated and vaporized on the vaporization surface, and the vaporized vapor enters the airflow channel 11 of the housing 10 through the vaporization cavity and is inhaled by the user. When the e-liquid in the e-liquid storage tank decreases gradually, air pressure in the e-liquid storage tank 13 drops, forming a negative pressure. The air pressure in the vaporization cavity 71 is relatively high, and the air pushes away the seal portion 31 and then flows into the e-liquid storage tank 13, to implement air pressure balance. In this way, it is ensured that sufficient e-liquid is absorbed on the porous body to maintain a vaporization effect.
In the present disclosure, in an operating process of the electronic cigarette vaporization apparatus 100, the e-liquid enters the porous body from the liquid absorbing surface of the porous body, is heated by the heating body on the vaporization surface of the porous body, and is vaporized to form vapor and is then exported. Because the e-liquid is continuously consumed by vaporization, the e-liquid storage tank 13 is in a state of negative pressure in this case, and the external air needs to be replenished to the liquid absorbing surface to restore balance of the internal and external pressure difference. In this case, the seal portion 31 in the first seal member 30 is pushed away and deformed by an air flow, and the seal portion 31 opens the vent channel 21. The air enters the e-liquid storage tank 13 through the vent channel 21, which implements a good vent effect and avoids problems of poor e-liquid supply and core burnt.
Therefore, in the electronic cigarette vaporization apparatus 100 of the present disclosure, by providing a vent channel 21 on the vaporization assembly 20, one seal portion 31 corresponding to the vent channel 21 is provided on the first seal member 30, and the vent channel 21 is opened and closed through the seal portion 31, so that the external air enters the e-liquid storage tank 13. In this way, air pressure balance in the electronic cigarette vaporization apparatus 100 is implemented, and smooth liquid supply of the electronic cigarette vaporization apparatus 100 is ensured, to enable the electronic cigarette vaporization apparatus 100 to implement complete vaporization, and improve user experience. In addition, the electronic cigarette vaporization apparatus 100 may further prevent the liquid in the e-liquid storage tank 13 from flowing out, preventing e-liquid leakage.
According to an embodiment of the present disclosure, referring to FIG. 1, FIG. 7, and FIG. 8, the vent channel 21 passes through along an extending direction from the liquid absorbing surface to the vaporization surface. When the e-liquid storage tank 13 is in a negative pressure state, the seal portion 31 opens the vent channel 21, and the air enters the e-liquid storage tank through the vent channel 21, so that the internal air pressure and the external air pressure are balanced and the e-liquid supply is smoother.
In the present disclosure, the seal portion 31 is switchable between a first state and a second state. The seal portion 31 is in the first state. In this case, the seal portion 31 closes the vent channel 21, to prevent the liquid in the e-liquid storage tank 13 from flowing out. When the seal portion 31 is in the second state, the seal portion 31 opens the vent channel 21, to allow the external air to enter the e-liquid storage tank 13 through the vent channel 21, the internal and external pressure difference of the e-liquid storage tank 13 is balanced, and the e-liquid supply is smoother.
Optionally, the seal portion 31 is in the second state. The seal portion 31 is deformed toward the e-liquid storage tank 13 to open the vent channel 21, to allow the external air to enter the e-liquid storage tank 13. The seal portion 31 is in the first state. The seal portion 31 is deformed toward the vaporization assembly 20 to close the vent channel 21.

The second seal member 60 is mounted in the housing 10. In addition, an outer edge of the second seal member 60 abuts against an inner wall of the housing 10, so that the second seal member 60 and the housing 10 are enclosed to form the e-liquid storage tank 13.
According to an embodiment of the present disclosure, when an air pressure in the e-liquid storage tank 13 is greater than or equal to an external atmospheric pressure, the seal portion 31 is in the first state. In this case, the seal portion 31 closes the vent channel 21, to prevent the liquid in the e-liquid storage tank 13 from flowing out. When the air pressure in the e-liquid storage tank 13 is less than the external atmospheric pressure, the seal portion 31 is in the second state.

When the seal portions 31 are in the first state, each seal portion 31 respectively covers a vent channel 21 corresponding to the seal portion 31. The first seal member 30 uses an elastic material member. For example, the first seal member 30 and the seal portion 31 are made of a material with a specific elastic deformation capacity such as soft rubber, to ensure that the seal portion 31 is deformed when the seal portion 31 is switched between the first state and the second state, to open or close the vent channel 21. According to an embodiment of the present disclosure, the first seal member 30 is made of silica gel material, and the seal portion 31 is made of a silica gel sheet.
According to an embodiment of the present disclosure, referring to FIG. 7 and FIG. 8, the vent channel 21 is a groove provided on an outer surface of the porous body, and the groove passes through the porous body along the extending direction from the liquid absorbing surface to the vaporization surface. The first seal member 30 is sleeved on the vaporization assembly 20, and the groove matches an inner wall of the first seal member 30 to form the vent channel 21.
In the present disclosure, the quantity of vent channels 21 is more than one, and the vent channels 21 are spaced on an outer side wall of the porous body. The quantity of seal portions 31 and arrangement positions of the seal portions 31 are in a one-to-one correspondence with the vent channels 21. It should be noted that a shape of the groove is not particularly limited. In different embodiments, a cross-sectional shape of the groove may be further a triangle, a rectangle, or an irregular shape with an opening on a side surface. Due to the opening on the side surface of the groove, when the porous body is assembled, the opening on the side surface of the groove is closed by the first seal member 30, to form the vent channel.
In an embodiment, the vent channel 21 is a through hole running through the porous body along the extending direction from the liquid absorbing surface to the vaporization surface. Optionally, the quantity of vent channels 21 is more than one, and the vent channels 21 are spaced on an inner edge of an outer periphery of the porous body. A cross section of the through hole may be in a shape of a circle. It should be noted that a shape of the through hole is not particularly limited.

In addition, the quantity of seal portions 31 and arrangement positions of the seal portions 31 are in a one-to-one correspondence with the vent channels 21.
In some specific embodiments of the present disclosure, as shown in FIG. 3 and FIG. 4, using the extending direction from the liquid absorbing surface to the vaporization surface as a preset direction, a cross section of the first seal member 30 perpendicular to the preset direction is an elongated structure, and multiple seal portions 31 are located on two ends of the elongated structure.

Certainly, a person skilled in the art can understand that a specific quantity of seal portions 31 and a specific size and thickness of each seal portion 31 can be specifically limited according to actual needs.
In an embodiment of the present disclosure, as shown in FIG. 3 and FIG. 4, an upper edge of the first seal member 30 abuts against the vaporization assembly 20, and the seal portion 31 is located on an inner wall of the upper edge of the first seal member.
In the present disclosure, as shown in FIG. 1 and FIG. 2, the first cover body 40 is in interference fit with the first seal member 30, and the first seal member 30 is in interference fit with the vaporization assembly 20. The first seal member 30 is in interference fit with the vaporization assembly 20.
According to an embodiment of the present disclosure, a vaporization cavity 71 is formed between the vaporization surface of the porous body and the second cover body 50, and vapor generated after vaporization is introduced into the vaporization cavity 71 and is finally exported through the airflow channel 11. Multiple vent holes 51 in communication with the airflow channel 11 are provided on the second cover body 50. Air enters into the vaporization cavity 71 through the vent hole 51. The multiple vent holes 51 cause the air to flow in evenly, and maintain the vapor in the vaporization cavity 71 and the air evenly mixed. The evenly arranged multiple vent holes 51 also increase air resistance when the air flows in. The user can feel sufficient air resistance when inhaling through the airflow channel 11, which improves an experience effect of inhaling vapor.

In an optional embodiment, an end of the vent channel 21 is in communication with the e-liquid storage tank 13, an other end of the vent channel 21 is in communication with the vaporization cavity 71, and the vent channel 21 is in communication with the external air through the vaporization cavity 71. When the air pressure of the e-liquid storage tank 13 decreases due to reduction of the e-liquid, because the vaporization cavity 71 is in communication with the air inlet hole 12, the air pressure of the vaporization cavity 71 is consistent with the outside world, which is higher than the air pressure of the e-liquid storage tank 13. Therefore, the seal portion 31 is pushed away by the air on a side of the vaporization cavity 71, and the air enters the e-liquid storage tank 13, to implement air pressure balance.

Certainly, in the present disclosure, other structures of the electronic cigarette vaporization apparatus 100 may be understandable and may be implemented, and are not described in detail in the present disclosure.
In summary, in the electronic cigarette vaporization apparatus 100 of the present disclosure, by providing a vent channel 21 on the vaporization assembly 20, one seal portion 31 corresponding to the vent channel 21 is provided on the first seal member 30, and the vent channel 21 is opened and closed through the seal portion 31, so that the external air may enter the e-liquid storage tank 13. In this way, air pressure balance in the electronic cigarette vaporization apparatus 100 is implemented, and smooth liquid supply of the electronic cigarette vaporization apparatus 100 is ensured, to enable the electronic cigarette vaporization apparatus 100 to implement complete vaporization, and improve user experience. In addition, the electronic cigarette vaporization apparatus may further prevent the liquid in the e-liquid storage tank 13 from flowing out, causing e-liquid leakage.
According to the present disclosure, an electronic cigarette is further provided, which includes the electronic cigarette vaporization apparatus 100 described in the foregoing embodiments. Because the electronic cigarette vaporization apparatus 100 according to the present disclosure has the foregoing technical effects, the electronic cigarette according to the embodiments of the present disclosure should also have a corresponding technical effect. In other words, the electronic cigarette of the present disclosure may effectively resolve problems of poor liquid supply and e-liquid leakage in the housing 10.
In the present disclosure, referring to FIG. 1 and FIG. 2, a principle of the electronic cigarette is that the liquid in the e-liquid storage tank 13 is introduced into the liquid absorbing surface of the vaporization assembly 20. When a user inhales, a sensor in the electronic cigarette is triggered, which sends a signal to drive the vaporization assembly 20 to start heating. The liquid is heated and vaporized on the vaporization surface, and the air flows in through the air inlet hole 12, to take away the vapor and air in the vaporization cavity 71. The vapor and air enter the airflow channel 11 through the first cover body 40 and a channel on the second seal member 60, and finally enter the mouth of the user. When the e-liquid in the e-liquid storage tank decreases, air pressure in the e-liquid storage tank 13 drops, forming a negative pressure. The air pressure on a side in the vaporization cavity 71 is relatively high, and the air pushes away the seal portion 31 and then flows into the e-liquid storage tank 13, to implement air pressure balance. Further, sufficient e-liquid may be absorbed on the porous body to maintain an effect of generating vapor.
Due to addition of a through hole or a groove (vent channel 21) on the porous body of the vaporization assembly 20, in an operating process of the electronic cigarette, the e-liquid passes through an e-liquid channel from the liquid absorbing surface to the vaporization surface, and the air is replenished to the e-liquid storage tank 13 through the added vent channel 21, thereby implementing a good vent effect. A phenomenon of e-liquid leakage and poor e-liquid flowing has been avoided.
In the present disclosure, other structures of the electronic cigarette vaporization apparatus 100 may be understandable and may be implemented, and are not described in detail in the present disclosure.
Although some specific embodiments of the present disclosure have been described in detail through examples, a person skilled in the art should understand that the foregoing examples are for description only, and not intended to limit the scope of the present disclosure. It should be understood by a person skilled in the art that modifications may be made to the foregoing embodiments without departing from the scope and spirit of the present disclosure. The scope of the present disclosure is limited by the appended claims.
