This application claims priority to Chinese Patent Application No. 202120513630.4, filed with the China National Intellectual Property Administration on Mar. 11, 2021 and entitled “VAPORIZER AND ELECTRONIC VAPORIZATION DEVICE”, which is incorporated herein by reference in its entirety.
TECHNICAL FIELDEmbodiments of this application relate to the field of electronic vaporization technologies, and in particular, to a vaporizer and an electronic vaporization device.
BACKGROUNDThere are aerosol-providing products, 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 a fragrance composite and/or an aerosol-generation article (for example, glycerol). In addition to the fragrance composite 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 enter a liquid storage cavity from the outside to serve as a supplement 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 is consumed, the liquid storage cavity is gradually in a negative pressure state, preventing fluid transfer 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 e-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.
SUMMARYAn embodiment of this application provides a vaporizer, configured to vaporize a liquid substrate to generate an aerosol, and including:
-
- a housing, where a liquid storage cavity configured to store a liquid substrate is formed in the housing;
- a vaporization assembly, having a vaporization surface and configured to vaporize at least part of the liquid substrate to generate an aerosol;

Through the vaporizer, the air channel supplements air to the liquid storage cavity from a position avoiding the interference fit region of the seal element, to relieve or balance a negative pressure of the liquid storage cavity, and a size of the air channel can be prevented from becoming uncontrollable due to squeezing and deformation of the interference fit region of the seal element.

In a preferred implementation, the seal element includes a first seal element arranged between the support and the vaporization assembly; and a first avoidance groove adjacent to the first part is arranged on the first seal element, and the second part is defined between the first avoidance groove and an inner surface of the holding space.
-
- two convex edges are arranged on the first seal element, and the first avoidance groove is formed by a gap between the at least two convex edges.
In a preferred implementation, a protruding height of the convex rib is greater than or equal to a protruding height of the at least two convex edges.
In a preferred embodiment, the second part is constructed to extend in a longitudinal direction of the vaporizer.
In a preferred implementation, the first part and the second part are substantially perpendicular to each other.
In a preferred implementation, the vaporization assembly includes a liquid channel running through the vaporization assembly in a length direction, and is in fluid communication with the liquid storage cavity through the liquid channel to absorb the liquid substrate.

Another embodiment of this application further provides a vaporizer, configured to vaporize a liquid substrate to generate an aerosol, and including:
-
- a liquid storage cavity, configured to store a liquid substrate;
- a vaporization assembly, configured to receive the liquid substrate of the liquid storage cavity and vaporize the liquid substrate to generate an aerosol;

An embodiment of this application further provides an electronic vaporization device, including a vaporizer configured to vaporize a liquid substrate to generate an aerosol, and a power supply mechanism configured to supply power to the vaporizer. The vaporizer includes the vaporizer described above.
In this application, by using the interference fit region which allows the air channel to avoid the flexible seal element, an air flow area of the air channel may be effectively prevented from a change as a result of a squeezing action from an interference fit while ensuring a sealing performance. As a result, efficiency of air entering the liquid storage cavity is difficult to meet design requirements, ensuring consistency of the air channel, and improving stability of product performances.

Further, in a more preferred implementation, a protruding height of the first convex rib 53 is greater than or equal to a protruding height of the convex edge 521, so as to avoid the convex edge 521 being squeezed by an inner wall of the holding space 64 of the support 60 and causing the first avoidance groove 52 to shrink and deform after assembly.
