Description

Technical Field

[0001] The utility model belongs to the field of oral care products, and particularly relates to a leak-proof electronic oral spray device. Background Art

[0002] A spray device, i.e., an oral sprayer, is used for spraying oral medications. For a traditional pressing-type oral sprayer, the user needs to frequently operate it to achieve spraying, inevitably resulting in uneven spraying, which is inconvenient to use. Moreover, the sprayed medications are in the form of tiny droplets that concentrate on the inner wall of the oral cavity, prone to overdosage, large loss, and waste of medications. In addition, the pressing-type oral sprayer relies on a pressurizing structure inside it to achieve pressurized liquid spraying, with a complex structure and a relatively large volume, which is not conducive to the assembly and application of the oral sprayer.
