[0002] An electronic atomizer is a device that generates mist by heating tobacco oil, and users simulate smoking by inhaling the mist. Currently, electronic cigarette atomizers on the market are usually filled with tobacco oil by opening oil filling holes on both sides, and the tobacco oil is injected from the oil filling holes on both sides.

[0003] This oil filling method has the following problems: Since the location of the oil filling hole is usually close to the side of the device, it may be difficult for users to accurately control the flow of liquid, especially when the liquid level in the liquid container is low, which may cause excessive liquid to enter the device, causing oil leakage or affecting the normal operation of the device. If the user accidentally pours the liquid outside the device during the oil filling process, or the liquid overflows due to careless operation, there will be a risk of liquid leakage; this will not only cause waste, but may also cause the surface of the device to become sticky and even affect the user's hand hygiene. In addition, the efficiency of oil injection on both sides is low.

[0004] Therefore, when designing an electronic atomizer, it is necessary to carefully consider the advantages and disadvantages of different oil filling methods, and weigh and select the most appropriate oil filling method based on user needs and overall considerations of product design.
