[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 atomizing dispensing device. 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. The inlet chamber is located inside the main body and outside the main body.

A mesh layer is installed on the upper surface of the partition layer, with the mesh aperture of the mesh layer covering the through holes being smaller than the outer diameter of the heat-conducting particles. The liquid quantitatively fed into the feed chamber by the screw valve is rapidly vaporized through high temperature. Then, the quantitative vapor obtained by the vaporization is output from the discharge guide channel to form a spray through the high-pressure gas entering the feed chamber. The heat-conducting particles increase the contact area and heating uniformity between the liquid and the heat source in the feed chamber, thereby improving the atomization efficiency, the fineness and uniformity of the atomized particles, and the accuracy and consistency of the atomized particle output.

[0020] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0021] Example 1: An atomizing dispensing device includes: a body 1, a discharge guide groove 2 formed on the lower end surface of the body 1, an inlet chamber 3 formed inside the body 1 and above the discharge guide groove 2, a partition layer 4 formed between the lower end of the inlet chamber 3 and the discharge guide groove 2, a plurality of through holes 41 spaced apart on the partition layer 4 connecting the inlet chamber 3 and the discharge guide groove 2, the upper end of the inlet chamber 3 being connected to the outlet end of a three-way connector 6, and one inlet end of the three-way connector 6 being connected to a pipe The feed end 131 of the screw valve 13 is connected to the discharge end 131 of the screw valve 13. The other inlet end of the three-way connector 6 is connected to the air supply unit 141 through the pipeline. The feed end 132 of the screw valve 13 is connected to the liquid supply unit 142 through the pipeline. Several heating rods 5 are embedded and installed in the body 1 and located outside the feed chamber 3. The feed chamber 3 is filled with heat-conducting particles. A mesh layer 7 is provided on the upper surface of the partition layer 4. The mesh aperture of the mesh layer 7 covering the through hole 41 is smaller than the outer diameter of the heat-conducting particles.

[0022] The screw valve, in conjunction with a three-way connector, quantitatively feeds liquid (such as distilled water or ethanol) into the feed chamber of the spray unit. The feed chamber is maintained at a constant temperature (e.g., 200°C, which can be adjusted according to the physicochemical properties of the liquid) by the heating rod. The liquid entering the feed chamber vaporizes under high temperature. During this process, the heat-conducting particles filling the feed chamber greatly increase the contact area between the liquid and the heat source, which also improves the uniformity of liquid heating, thereby increasing the vaporization speed and efficiency as well as the uniformity of steam formation.

[0023] The aforementioned mesh layer 7 is a metal mesh layer.

[0024] A pressure regulating valve 143 is installed on the pipeline connecting the gas supply unit 141 and the three-way connector 6.

[0025] The lower end of the aforementioned body 1 is equipped with an atomizing nozzle 9 that communicates with the discharge guide 2.

[0026] The aforementioned body 1 is a metal thermally conductive body.

[0027] A temperature sensor 8 is embedded in the aforementioned body 1.

The other inlet end of the three-way connector 6 is connected to the air supply unit 141 through the pipeline. The feed end 132 of the screw valve 13 is connected to the liquid supply unit 142 through the pipeline. Several heating rods 5 are embedded and installed in the body 1 and located outside the feed chamber 3. The feed chamber 3 is filled with heat-conducting particles. A mesh layer 7 is provided on the upper surface of the partition layer 4. The mesh aperture of the mesh layer 7 covering the through hole 41 is smaller than the outer diameter of the heat-conducting particles.

[0029] The hot steam formed by rapid vaporization is blown out by the gas that enters the feed chamber through the same three-way connector;

[0030] In the above process, the amount of liquid supplied to the feed chamber can be adjusted by adjusting the motor speed of the screw valve, thereby adjusting the final amount of steam sprayed to adapt to different detection environments and detection requirements; the amount of air injected into the feed chamber can also be adjusted by adjusting the pressure regulating valve, thereby adjusting the output rate of a certain amount of steam to match different spraying requirements.

[0031] The aforementioned mesh layer 7 is a metal mesh layer.

[0032] A pressure regulating valve 143 is installed on the pipeline connecting the gas supply unit 141 and the three-way connector 6.

[0033] A temperature sensor 8 is embedded in the aforementioned body 1.

[0034] The aforementioned heat-conducting particles are metal particles.

[0035] The upper end face of the aforementioned body 1 has an installation groove 10 that communicates with the upper end of the feeding chamber 3, and a feeding baffle 11 embedded in the installation groove 10 is fixedly installed on the body 1 by a pressure block 12.

[0036] The feed baffle 11 has a feed hole 111 extending along its length. The pressure block 12 has a feed groove 121 that mates with the feed hole 111 on its lower surface facing the feed baffle 11. The feed groove 121 is connected to the outlet end of the tee connector 6 through a pipeline.

[0037] The length of the feed groove 121 is the same as the length of the feed hole 111, the width of the feed groove 121 is greater than the width of the feed hole 111, and the length of the feed hole 111 is the same as the width of the upper end of the feed chamber 3.

[0038] The working principle of this utility model is as follows:

[0039] The screw valve, in conjunction with a three-way connector, quantitatively feeds liquid (such as distilled water or ethanol) into the feed chamber of the spray unit. The feed chamber is maintained at a constant temperature (e.g., 200°C, which can be adjusted according to the physicochemical properties of the liquid) by the heating rod. The liquid entering the feed chamber vaporizes under high temperature. During this process, the heat-conducting particles filling the feed chamber greatly increase the contact area between the liquid and the heat source, which also improves the uniformity of liquid heating, thereby improving the vaporization speed and efficiency as well as the uniformity of steam formation.

[0040] The hot steam generated by rapid vaporization is blown out through the atomizing nozzle under the action of the gas that enters the feed chamber through the same three-way connector;

[0041] In the above process, the amount of liquid supplied to the feed chamber can be adjusted by adjusting the motor speed of the screw valve, thereby adjusting the final amount of steam sprayed to adapt to different detection environments and detection requirements; the amount of air injected into the feed chamber can also be adjusted by adjusting the pressure regulating valve, thereby adjusting the output rate of a certain amount of steam to match different spraying requirements.

[0042] When using the above-mentioned atomizing dispensing equipment, the liquid quantitatively input into the feed chamber by the screw valve is rapidly vaporized by high temperature. Then, the quantitative vapor obtained by the vaporization is output from the discharge guide groove to form a spray by the high-pressure gas entering the feed chamber. The contact area between the liquid and the heat source in the feed chamber and the uniformity of heating are increased by heat-conducting particles, thereby improving the atomization efficiency, the fineness and uniformity of the atomized particles, and the accuracy and consistency of the output of atomized particles.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
