Description

Technical Field

[0001] The utility model relates to a fine water mist nozzle, and relates to the technical field of nozzle equipment. Background Art

[0002] A watering can is a commonly used water spraying device in people's daily life. The liquid in the can can be sprayed out for use by simply pressing the trigger on the spray head. The structure is simple and easy to use.

[0003] In the existing manual spray nozzle structure, the piston is pushed to move and pump water by pressing the trigger, and the nozzle adjusts the water column form, that is, an adjustment from a coarse water column to a water mist form. However, due to different requirements for the particle size of the water column or water mist in actual use, most of the existing spray nozzles can only spray coarse particles of water column or water mist, which leads to uneven wetting and poor use effect when used in some special cases. The patent technology with announcement number CN220657944U discloses an ultra-fine spray nozzle and an ultra-fine spray nozzle containing it, which relates to the field of spray nozzles, including a nozzle body, a baffle is provided in the nozzle body, a spray eye is penetrated on the baffle, and liquid is sprayed from the spray eye. A plurality of guide plates are arranged in a circular array on the inner side of the baffle in the nozzle body, one side of the guide plate is tangent to the spray eye, and a guide groove is formed between adjacent guide plates, and the guide groove is a straight groove. In the present application, the liquid is broken into extremely fine mist through two accelerated rotations (the liquid completes the first accelerated rotation along the guide plate and the second accelerated rotation at the end of the guide groove). The present application can spray the liquid in the bottle into a mist with a particle diameter less than 20um, thereby enhancing the user experience. However, in this structure, only the guide plate is set on the same plane to simply divide the water flow, so that the water flow rotates to obtain a fine water mist effect. The fine water mist effect obtained by a simple passive method is still limited. Utility Model Content
