The lifting mechanism 221 is arranged based on the first water collecting trough 271. A second water collecting trough 272 is arranged below the two ends of the conveying mechanism 21.

[0051] A sensor is provided at each cleaning or washing position and at the electric push rod 261. The sensor is used to detect the glassware 3, such as a laser sensor, etc. The sensor is linked with the water supply pump 281, the drainage pump 282, the conveying mechanism 21, the electric push rod 261 and each electric valve (the sensor is connected to the single-chip microcomputer, and the single-chip microcomputer is connected to the water supply pump 281, the drainage pump 282, the conveying mechanism 21, the electric push rod 261 and each electric valve).

[0052] The principle of the present invention is:

[0053] During the use of the present invention, the glassware 3 to be cleaned is placed on the conveying mechanism 21 (such as Figure 1 The glassware 3 is opened downward and placed on two chain conveyor belts at the same time; it is transported to the internal cleaning device 22 and the external cleaning device 24 via the conveying mechanism 21.

[0054] When the sensor senses the glassware 3, the conveying mechanism 21 stops moving. At this time, the glassware 3 is located above the internal cleaning device 22. At this time, the water supply pump 281 operates to supply water to the piston chamber 2211 (the corresponding electric valve is opened). Under the action of water pressure, the internal cleaning brush 224 rises. When the piston 2212 reaches the height of the first conveying branch pipe, the cleaning water enters the first conveying main pipe through the first conveying branch pipe. During the process, the first conveying branch pipe with a suitable height can be selected according to the type of glassware 3. When the cleaning water enters the first conveying main pipe, due to The first venturi tube 2221 on the main pipe can draw the cleaning liquid in the first cleaning liquid storage box 223 into the main pipe and mix it with the cleaning water. The mixed cleaning water enters the internal cleaning brush 224 through the first connecting cavity 2214 and the first rotating joint 2215. At this time, the cleaning water is sprayed out through the first pushing mechanism 2244 and drives the internal cleaning brush 224 to rotate, thereby realizing the rotation cleaning of the inside of the glassware 3; the sensor can also measure the height of the glassware 3, and can realize automatic adjustment and cleaning of glassware 3 at different heights.

[0055] At the same time, the water inlet pipe 244 is connected to the faucet or the booster pump. Taking the faucet as an example, turn on the faucet, and the water in the faucet reaches the external cleaning brush 243 through the second delivery pipe 245 (the corresponding electric valve is opened). On the one hand, it absorbs the cleaning liquid, and on the other hand, it rotates under the action of water force to clean the outside of the glass container 3. It should be noted that the external cleaning brush 243 includes two groups, one group plays a pushing role, and the other group plays a rotating role, so as to clean the entire internal and external surfaces of the glass container 3.

[0056] When cleaning is completed, the drainage pump 282 pumps out the water in the piston chamber 2211, the piston 2212 moves downward and drives the internal cleaning brush 224 to descend, and the glassware 3 after cleaning can go to the next position; by analogy, after the glassware 3 is cleaned for a certain period of time at each cleaning position, it is pushed forward for cleaning in turn (taking the equal spacing of each cleaning position and the cleaning position as an example, when the first glassware 3 passes the sensor above the electric push rod 261, the telescopic rod of the electric push rod 261 extends to limit the glassware 3 behind, and when the first glassware 3 reaches the first cleaning position, the telescopic rod of the electric push rod 261 retracts and releases the limit, and so on; when the cleaning positions and the cleaning positions are not equidistant, it is necessary to determine the action time of the electric push rod 261 according to the spacing and the running speed of the conveying mechanism 21. The process involves relatively simple control and will not be repeated), and then washed with water for cleaning, and finally intercepted and collected at the outlet of the conveying mechanism 21. At this time, the experimenter can take the cleaned glassware 3 and put it into the oven for drying.

[0057] During the cleaning process, the cleaning water can be quickly discharged through the plate chain conveyor belt, and then discharged to the second water collecting tank 272 through the first water collecting tank 271, and then discharged.

[0058] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
