This application claims priority to Chinese Patent Application No. 202010545792.6, entitled “E-CIGARETTE VAPORIZER AND E-CIGARETTE” filed with the China National Intellectual Property Administration on Jun. 16, 2020, which is incorporated herein by reference in its entirety.
Embodiments of this application relate to the field of e-cigarette technologies, and in particular, to an e-cigarette vaporizer and an e-cigarette
There are aerosol-providing articles, for example, e-cigarette devices. The devices generally include e-liquid. The e-liquid is heated to be vaporized, so as to generate an inhalable vapor or aerosol. The e-liquid may include nicotine and/or ultraviolet fragrance and/or an aerosol-generation article (for example, glycerol) in addition to the ultraviolet fragrance in the e-liquid.
An existing e-cigarette device generally includes a porous ceramic body that has a large amount of micropores provided inside and is configured to absorb and conduct the e-liquid, and a heating element is arranged on a surface of the porous ceramic body and configured to heat and vaporize the absorbed e-liquid. The micropores in the porous body are used as channels for the e-liquid to infiltrate and flow to a vaporization surface, and also used as air exchange channels for air to replenish and enter a liquid storage cavity from the outside to maintain balance of the air pressure in the liquid storage cavity after the e-liquid in the liquid storage cavity is consumed, so that bubbles are generated in the porous ceramic body when the e-liquid is heated, vaporized, and consumed, and then the bubbles emerge from a liquid absorbing surface and then enter the liquid storage cavity.
For the existing e-cigarette device, as the e-liquid in the liquid storage cavity arranged inside is consumed, the liquid storage cavity is gradually in a negative pressure state, to prevent fluid transmission to a certain extent, so that the e-liquid is less conveyed to the vaporization surface through the micropore channels of the porous ceramic body for vaporization. Particularly, when the existing e-cigarette device is in a continuous inhaling and use state, the air outside the liquid storage cavity is difficult to pass through the micropore channels of the porous ceramic body to enter the liquid storage cavity in a short time, to slow down the speed of conveying the q-liquid to the vaporization surface, and insufficient e-liquid supplied to the heating element will cause the temperature of the heating element to be excessively high, resulting in decomposition and volatilization of the e-liquid components to generate harmful substances such as formaldehyde.
In order to resolve the problems in the prior art that a negative pressure formed in an e-cigarette liquid storage cavity during use affects e-liquid conveying, embodiments of this application provide an e-cigarette vaporizer for promoting smooth transmission of e-liquid and an e-cigarette.

In some embodiments, the rigid support frame may be substantially in a ring shape with a lower end being an opening, and an inner space thereof is used for accommodating and holding the flexible silicone sleeve 50 and the porous body 30.
The flexible silicone base 70 is arranged on an end portion of the liquid storage cavity 12 facing the far end, and a shape of the flexible silicone base matches a cross section of an inner contour of the outer housing 10, to seal the liquid storage cavity 12 and prevent the liquid substrate from leaking out from the liquid storage cavity 12. Further, to prevent shrinkage and deformation of the flexible silicone base 70 made of a flexible material from affecting the sealing tightness, the rigid support frame 60 is accommodated in the flexible silicone base 70 to support the flexible silicone base.
After mounting, to ensure smooth conveying of the liquid substrate and output of the aerosol, a first liquid guide channel 71 for the liquid substrate to flow through is provided on the flexible silicone base 70, a second liquid guide channel 61 is correspondingly provided on the rigid support frame 60, and a third liquid guide channel 51 is provided on the flexible silicone sleeve 50.

In this embodiment, a specific distance is maintained between the vaporization surface 32 and the end cover 20, and at least a part of a vaporization chamber is surrounded by the vaporization surface 32 and the end cover 20 and is formed for the aerosol to escape. Certainly, on one hand, the vaporization chamber is in airflow communication with the air inlet hole 24 on the end cover 20 and is configured for the external air to enter the vaporization chamber; and on the other hand, the vaporization chamber is in airflow communication with the vapor conveying tube 11 and is configured to output the aerosol generated by and escaping from the vaporization surface 32.
After a negative pressure vacuum is generated in the liquid storage cavity 12 with the consumption of the liquid substrate, to ensure that the liquid substrate can still be smoothly absorbed by the porous body 30, an air channel is also provided in the vaporizer 100. Further referring to
Further, a thickness and a position of the first blocking part 73 are designed, and the thickness is between 0.2 mm and 0.5 mm. In addition, in some embodiments, the first blocking part 73 is thinner than other parts of the flexible silicone base, so that the first blocking part 73 is easier to deform. In addition, hardness of a material used for the flexible silicone base 70 may range from 20 A to 40 A in Shore Hardness A. Therefore, after the negative pressure in the liquid storage cavity 12 is gradually increased, the pressure is transmitted through fluid, so that a pressure at an upper end of the first blocking part 73 is reduced, to allow the upper end of the first blocking part to tilt up and deform shown in
It can be learned from

After the groove is mounted, the air channel is formed between the groove 63a and an inner wall of the flexible silicone base 70a for air in the vaporization chamber to enter the liquid storage cavity 12.

Alternatively, in another optional embodiment,
According to the vaporizer and the e-cigarette, a flexible silicone component can be elastically deformed in response to the negative pressure in the liquid storage cavity due to flexibility, so as to open the air channel, so that the external air can pass through the air channel and enter the liquid storage cavity to partially relieve a negative pressure degree, so as to smoothly convey the liquid substrate.
Certainly, in the foregoing embodiments, the flexible component has a deformation resistance capability, to allow the air channel inside the liquid storage cavity 12 to be in a normally closed state during non-inhalation during use, so that the liquid storage cavity 12 is maintained in a specific negative pressure state. During inhalation, only when the negative pressure inside the liquid storage cavity 12 is increased to exceed a specific critical threshold, the flexible component is deformed in response to the change of the negative pressure for air to enter. Therefore, a case that the liquid storage cavity 12 is not in a constant normal pressure state can be prevented, and the liquid substrate can be prevented from leaking through the porous body 30.
