[0046] Electronic atomizing devices integrate circuit boards with spaced-apart electrodes and microphones. Current technologies typically use multiple spaced-apart seals on the circuit board, with at least one seal for sealing the electrode and at least one seal for sealing the microphone. However, this assembly process requires individual assembly of these seals, increasing assembly steps and potentially leading to increased cumulative tolerances. Furthermore, to effectively limit the movement of these seals, multiple positioning grooves are needed on the circuit board and the support components within the electronic atomizing device, adding to the manufacturing process.

[0047] Based on this, in order to solve the above problems, this application designs a sealing element that can simultaneously seal the microphone and electrode body on the circuit board, thereby simplifying the number of internal components of the electronic atomizing device, reducing assembly steps to reduce tolerance accumulation, and effectively saving material costs and assembly costs.
