Background

An electronic atomizing device is a device for atomizing a substrate to be atomized into aerosol, and is widely used in daily life.

Typically, electronic nebulizers comprise only one nebulizer, and nebulizers are only capable of storing one type, i.e. one type of matrix to be nebulized, having one taste. On the one hand, only one atomizer can be designed to be relatively large in volume so as to store relatively more capacity of the substrate to be atomized, so that the atomization core in the atomizer can work for a long time in an accumulated mode, and the working performance of the atomization core can be reduced before the substrate to be atomized is completely consumed, so that the atomization effect such as taste generated by the operation of the atomization core is attenuated, the suction taste of a user is reduced, and the user experience is poor. On the other hand, in the case that some users want to obtain more than one taste, the atomizer in the electronic atomization device needs to be replaced or refilled, and the operation mode of obtaining more tastes is complicated, so that the user experience is poor. In addition, for the existing electronic atomization device with a relatively detachable top cover with a suction nozzle, the reliability of positioning and fixing of the top cover is low especially after multiple disassembly and assembly, atomized matrixes have risks of leakage, and the stability of the components in the electronic atomization device is reduced due to positioning deviation caused by disassembly and assembly of the top cover, so that the defects of reduced assembly stability and reduced working stability are caused.
