Definitions
- Embodiments of this application relate to the field of electronic atomization technologies, and in particular, to an atomizer and an electronic atomization device.
- aerosol-providing articles for example, e-cigarette devices.
- the devices generally include e-liquid.
- the e-liquid is heated to be atomized, so as to generate an inhalable vapor or aerosol.
- the e-liquid may include nicotine and/or fragrance and/or an aerosol-generation article (for example, glycerol), except for the 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 atomize the absorbed e-liquid.
- micropores in the porous body are used as channels for the e-liquid to infiltrate and flow to an atomization 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, atomized, and consumed, and then the bubbles emerge from a liquid absorbing surface and then enter the liquid storage cavity.
- 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 atomization surface through the micropore channels of the porous ceramic body for atomization.
- the air outside the liquid storage cavity can hardly pass through the micropore channels of the porous ceramic body to enter the liquid storage cavity in a short time, slowing down a speed of conveying the e-liquid to the atomization surface, and insufficient e-liquid supplied to the heating element will cause a temperature of the heating element to be excessively high, resulting in decomposition and volatilization of e-liquid components to generate harmful substances such as formaldehyde.
- An embodiment of this application provides an atomizer, including a housing, where the housing is internally provided with:
- a first groove is provided on the side surface of the holder, and the first channel portion is defined and formed between the first groove and the sealing element.
- a depth dimension of the first groove is greater than a width dimension.
- a second groove is provided on the upper surface of the holder, and the second channel portion is defined and formed between the second groove and the sealing element.
- a width dimension of the second groove is greater than a depth dimension.
- the first channel portion includes an extending direction different from that of the second channel portion.
- the first channel portion is basically perpendicular to the second channel portion.
- an extension length of the first channel portion is greater than an extension length of the second channel portion.
- the sealing element at least partially covers the holder and exposes an air inlet end and/or an air outlet end of the air channel.

- the power supply mechanism 200 includes a sensor 250 , configured to sense an inhalation airflow generated by the atomizer 100 during inhalation, so that the controller 220 controls the battery core 210 to supply power to the atomizer 100 according to a detection signal of the sensor 250 .

The heating element heats at least a part of the liquid substrate in the liquid guide element to generate an aerosol when powered on.
- the liquid guide element includes flexible fibers such as cotton fibers, non-woven fabrics, and glass fiber ropes, or includes porous materials with a microporous structure, such as porous ceramics.

- a side of the porous body 30 facing away from the atomization surface 310 is in fluid communication with the liquid storage cavity 12 , so as to absorb the liquid substrate, then a microporous structure inside the porous body 30 transmits the liquid substrate to the atomization surface 310 to be heated and atomized to form the aerosol, and the formed aerosol is released or escapes from the atomization surface 310 into the atomization chamber 340 .
- the heating element 40 is formed on the atomization surface 310 ; and after assembly, the second electrical contact 21 abuts against the heating element 40 , so as to supply power to the heating element 40 .
