TECHNICAL FIELD

[0001] The utility model relates to a point gum technical field, especially in a kind of quantitative spray mechanism. BACKGROUND

[0002] Atomization refers to the operation of dispersing liquid into small droplets by nozzle or high-speed airflow, and the methods of liquid atomization include pressure atomization, rotating disc atomization, gas atomization and acoustic atomization, etc., which convert liquid into small droplets and spray in mist form. High-pressure air atomization is usually used for atomization of low-viscosity liquids (such as low-viscosity glue), and the atomized liquid can improve the uniformity of spraying. However, the atomizer in the prior art cannot accurately control the amount of spray. SUMMARY

[0003] The technical problem to be solved by the utility model is to provide a quantitative spray mechanism, which improves the fineness and uniformity of atomized particles and improves the accuracy and consistency of atomized particle output.

[0004] To solve the above technical problems, the utility model adopts the technical scheme of a quantitative spray mechanism, comprising: a body, a discharge guide groove is formed on the lower end face of the body, a feed cavity is formed inside the body above the discharge guide groove, a partition layer is formed between the lower end of the feed cavity and the discharge guide groove, a plurality of through holes are formed on the partition layer and spaced apart, the through holes communicate the feed cavity and the discharge guide groove, the upper end of the feed cavity communicates with the outlet end of a three-way connector, one inlet end of the three-way connector is connected with the discharge end of a screw valve through a pipeline, the other inlet end of the three-way connector is connected with a gas supply unit through a pipeline, the feed end of the screw valve is connected with a liquid supply unit through a pipeline, and a plurality of heating rods are embedded and installed outside the feed cavity in the body.

[0005] The further improved scheme in the above technical scheme is as follows:

[0006] 1. In the above scheme, a pressure regulating valve is installed on the pipeline connecting the gas supply unit and the three-way connector.

[0007] 2. In the above scheme, a mist atomizing nozzle is installed on the lower end of the body and communicates with the discharge guide groove.

[0008] 3. In the above scheme, the body is a metal heat-conducting body.

[0009] 4. In the above scheme, a temperature sensor is embedded and installed in the body.

[0010] 5. In the above scheme, the upper end face of the main body is provided with an installation groove that communicates with the upper end of the feeding chamber, and a feeding baffle embedded in the installation groove is fixedly installed on the main body by a pressure block.

[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0012] This utility model relates to a quantitative spraying mechanism. A discharge guide groove is formed on the lower end face of the main body. An inlet chamber is formed inside the main body above the discharge guide groove. A partition layer is formed between the lower end of the inlet chamber and the discharge guide groove, spaced apart from each other. Several through holes are spaced apart on this partition layer, connecting the inlet chamber and the discharge guide groove. The upper end of the inlet chamber is connected to the outlet end of a three-way connector. One inlet end of the three-way connector is connected to the outlet end of a screw valve via a pipeline, and the other inlet end of the three-way connector is connected to an air supply unit via a pipeline. The inlet end of the screw valve is connected to a liquid supply unit via a pipeline. Several spaced heating rods are embedded and installed inside the main body, outside the inlet chamber. High temperature causes the liquid quantitatively input into the inlet chamber by the screw valve to rapidly vaporize. The high-pressure gas entering the inlet chamber then propels the quantitatively vaporized steam outward from the discharge guide groove, forming a spray. This improves both the fineness and uniformity of the atomized particles and the accuracy and consistency of the atomized particle output. Attached Figure Description
