Description

Technical Field

[0001] This utility model relates to the field of ice spray guns, and in particular to ice spray gun nozzles for dry ice cleaning machines. Background Technology

[0002] A dry ice cleaner is a type of cleaning machine that uses high-pressure air to propel dry ice particles through an ice spray gun onto the work surface that needs cleaning. The physical reaction caused by the temperature difference causes different substances to detach at different contraction rates. Currently, most cleaning machines on the market have small-diameter nozzles, resulting in lower efficiency for large-area cleaning, and they either lack ice-crushing capabilities or have complex structures. Utility Model Content

[0003] The technical problem this invention aims to solve is: to address the technical problems described in the background art, this invention provides an ice spray nozzle for a dry ice cleaning machine. The dry ice is pulverized by an ice crushing head, increasing the pressure as the dry ice travels from the container to the spray chamber, and is then ejected outwards through the conical spray chamber, thereby increasing the release flow rate, cleaning area, and efficiency.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A dry ice cleaning machine ice spray gun nozzle includes an ice spray gun nozzle body, a connector at one end of the ice spray gun nozzle body, and a nozzle at the other end of the ice spray gun nozzle body. The ice spray gun nozzle body has a cavity and a spray cavity. The connector, the cavity, and the spray cavity are connected in sequence. An ice crushing head is fixed in the cavity. The spray cavity is a conical cavity. The smaller opening of the spray cavity is connected to the cavity, and the larger opening of the spray cavity is the nozzle.

[0006] Specifically, the ice crusher head is olive-shaped.

[0007] Specifically, the nozzle is square.

[0008] Specifically, the smaller opening of the spray chamber is a circular opening.

[0009] Specifically, the opening connecting the cavity and the spray cavity is a conical opening.

[0010] Specifically, the connector is a round tube with threads on its inner wall.

[0011] The beneficial effects of this utility model are as follows: This utility model provides an ice spray nozzle for a dry ice cleaning machine. Dry ice is pulverized by an ice crushing head, increasing the pressure as the dry ice travels from the container to the spray chamber, and is then ejected outwards through the conical spray chamber, thereby increasing the release flow rate, cleaning area, and efficiency.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the internal structure of this utility model.

[0018] Combined with appendix Figure 1 and attached Figure 2 As shown, a dry ice cleaning machine ice spray gun nozzle includes an ice spray gun nozzle body 1, a connector 2 at one end of the ice spray gun nozzle body 1, and a nozzle 3 at the other end of the ice spray gun nozzle body 1. The ice spray gun nozzle body 1 has a cavity 4 and a spray cavity 5. The connector 2, the cavity 4, and the spray cavity 5 are connected in sequence. An ice crushing head 6 is fixed in the cavity 4. The spray cavity 5 is a conical cavity. The smaller opening of the spray cavity 5 is connected to the cavity 4, and the larger opening of the spray cavity 5 is the nozzle 3.

[0019] The ice crusher head 6 is olive-shaped.

[0020] Nozzle 3 is a square opening.

[0021] The smaller opening of the spray chamber 5 is a round opening.

[0022] The opening connecting the cavity 4 and the spray cavity 5 is a conical opening.

[0023] Connector 2 is a round tube with threads on its inner wall.

[0024] The working principle of this application is as follows: Compressed air mixed with dry ice enters the nozzle body 1 of the ice spray gun from the connector 2. After the dry ice impacts the ice crushing head 6, it will be partially broken into smaller pieces and evenly divided into two streams of mixed dry ice airflow by the ice crushing head 6. The two streams of airflow carrying dry ice continue to pass over the ice crushing head 6, mix and collide with each other, and some of the dry ice will become even smaller. The compressed air accumulates in the cavity 4. At this time, the compressed air pressure is relatively high and needs to be released. The connection between the cavity 4 and the spray chamber 5 is a conical opening. When the compressed air passes through the conical opening, the pressure gradually increases as the pipe becomes narrower. When the compressed air enters the circular opening at the feed end of the spray chamber 5, the pressure increases further. As it flows towards the nozzle 3, the pressure is gradually released and the flow rate increases further. The compressed air flows into the conical spray chamber 5 from the smaller circular opening and finally exits from the square nozzle 3. The pressure is gradually released further and the flow rate increases further. The increased flow rate means increased cleaning power, thus improving efficiency.

[0025] This application can make the dry ice finer and increase the nozzle diameter without reducing the spray pressure, thereby increasing the cleaning area and efficiency per unit time.

[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
