Description

Technical Field

[0001] This utility model belongs to the field of atomizing devices, specifically relating to a quantitative atomizing device with automatic liquid injection function. Background Technology

[0002] Existing equipment typically employs multi-stage spraying technology or novel powder materials to improve atomization effect and efficiency. However, in practical applications, atomization efficiency is still difficult to achieve ideal values. Problems such as high energy consumption, large equipment size, and complex operation continue to hinder the widespread application and large-scale industrial production of powder spraying equipment.

[0003] In existing technologies, the atomization volume of the device is difficult to control during use, resulting in the loss and waste of disinfectant, improper use of disinfectant, and unstable disinfectant reflux.

[0004] Therefore, a quantitative atomizing device with automatic liquid injection function is proposed. It can automatically and accurately control the atomization volume according to the preset disinfectant volume. The atomizing device with automatic quantitative liquid addition function adopts a combination of mechanical and electrical control to accurately control the liquid level and avoid the unstable backflow situation relying solely on the height difference of the parts.

The atomizing pump applies pressure to the inside of the atomizing cup through the transfer pipe, causing the liquid inside the atomizing cup to form mist and spray out from the atomizing interface. When there is too much liquid inside the atomizing cup, the dual-head peristaltic pump draws the excess liquid back into the atomizing cup through the second water outlet pipe and flows back into the storage bottle through the first water inlet pipe.

[0008] Preferably, the liquid storage bottle includes a fixing tube, a rubber stopper, a first circular hole, a second circular hole, a first water outlet pipe, and a first water inlet pipe; the fixing tube is threaded onto the upper end of the liquid storage bottle, and the rubber stopper is fixedly connected to the upper end of the fixing tube.

[0014] The beneficial effects of this invention are as follows: Liquid is placed inside the storage bottle, and the dual-head peristaltic pump and atomizing pump are turned on. The dual-head peristaltic pump draws the liquid from the storage bottle into the atomizing cup through the first outlet pipe and the second inlet pipe. The atomizing pump applies pressure to the inside of the atomizing cup through the transfer pipe, causing the liquid inside the atomizing cup to form mist which is then sprayed out from the atomizing interface. When there is too much liquid inside the atomizing cup, the dual-head peristaltic pump draws the excess liquid back through the second outlet pipe and flows it back into the storage bottle through the first inlet pipe. This solves the problems of existing devices where the liquid injection volume is difficult to control, leading to disinfectant loss and waste, improper use of disinfectant, and unstable disinfectant return.
