The utility model relates to electronic atomization technical field, specifically disclose an atomization device, include: casing, be equipped with liquid storage cavity, atomization air channel and detection air channel in casing, liquid storage cavity is connected with atomization air channel, and detection air channel is connected with atomization air channel, and airflow sensor, airflow sensor sets up in casing, and airflow sensor sets up in detection air channel, wherein, atomization device is in storage and transportation state, and the up and down direction is parallel with vertical direction, in the up and down direction, the position of airflow sensor in casing is higher than the bottom of liquid storage cavity. Make atomization device in warehousing, transportation, use process, airflow sensor is always in the position above the bottom of liquid storage cavity, if liquid leakage or condensate is produced when sucking occurs in liquid storage cavity, and liquid leakage and condensate flow according to gravity downwards, will not flow to the airflow sensor located above, can guarantee that liquid leakage will not enter airflow sensor, will not damage airflow sensor, and will not cause airflow sensor false start.

The invention discloses an elevator star sealing contactor contact adhesion test method, which comprises a display system, a control system, a driving system and an execution system, and is characterized in that the control system comprises a solid-state relay, and the display system comprises a switch; the test method comprises the following steps: S1, a variable voltage regulator is adopted to supply power to a system, and voltage is regulated to a voltage value matched with the load demand of a tested elevator star sealing contactor; s2, outputting a solid-state signal through a control system, controlling a solid-state relay to work in a random voltage switching SCR output mode, and shortening the link transmission time and controlling the detected star sealing contactor to act at high frequency by utilizing the high-speed response low-delay characteristic of the solid-state relay; meanwhile, feedback signals of a solid-state relay are collected, and the delay time of a control system of the system is obtained through calculation of a built-in algorithm of the control system, so that the contact feedback time of the star sealing contactor is accurately calculated. The testing process is transparent, data are clear, real-time monitoring is achieved, and results are judged in real time.
