[0003] During the carbon dioxide cleaning process, a cleaning nozzle is used to spray the dry ice after the carbon dioxide solidifies. However, the interior of the existing cleaning nozzle only throttles the carbon dioxide liquid through a venturi tube and does not have a certain adjustment structure, which results in the same spray speed of the carbon dioxide liquid. It is not convenient to spray when the spraying area is small, the spraying efficiency is low, and condensation water is easy to appear on the surface of the nozzle. Summary of the invention

[0007] As a preferred embodiment of the present invention, a rubber sleeve is fixedly connected to the interior of the annular groove, and the rubber sleeve is sleeved on the surface of the lead sleeve.

[0008] As a preferred embodiment of the present invention, both sides of the lead sleeve 1 are provided with oblique openings, and the width of the inner wall of the oblique openings is smaller than the wall thickness of the lead sleeve 1.

[0009] As a preferred embodiment of the present invention, the maximum diameter of the adjusting cone is smaller than the minimum inner diameter of the venturi tube, and pull plates are fixedly connected to both sides of the lead sleeve.

[0011] To achieve the above object, the present invention also provides a working method for cleaning a nozzle with carbon dioxide, characterized in that the working method is as follows:

[0012] Inject the treated liquid carbon dioxide into the Venturi tube, rotate the nozzle, move the support tube downward, and drive the adjusting cone to get stuck in the Venturi tube, thereby reducing the outflow of liquid carbon dioxide and increasing the outflow speed of liquid carbon dioxide. After forming a solid state, it is sprayed out from the top of the nozzle. Compressed air is injected into lead sleeve 1 and lead sleeve 2 through the air supply pipe and takes away the cold generated by the nozzle.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention drives the regulating cone through the support tube of the nozzle to clamp into the minimum inner diameter of the venturi tube, thereby reducing the outflow of liquid carbon dioxide, increasing the outflow speed of liquid carbon dioxide, and making the efficiency of liquid carbon dioxide to form a solid state higher. The air supply mechanism then insulates the surface and interior of the nozzle to reduce the cold amount on the nozzle surface and the generation of condensed water on the surface of the nozzle, thereby having the advantage of high spraying efficiency.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] refer to Figure 1An air supply mechanism 7 is provided on the surface of the nozzle 3, and the air supply mechanism 7 includes a lead sleeve 1 71, a lead sleeve 2 72, an annular groove 73 and an air supply pipe 74. The lead sleeve 1 71 is fixedly connected to the surface of the nozzle 3, the lead sleeve 2 72 is fixedly connected to the inside of the nozzle 3, the annular groove 73 is opened at the top of the mounting sleeve 1, and the bottom end of the lead sleeve 1 71 extends to the inside of the annular groove 73. The air supply pipe 74 is connected to the tops of both sides of the lead sleeve 1 71, and the nozzle 3 is connected to the lead sleeve 1 71 through the through hole 6.

[0028] As a technical optimization solution of the present invention, by providing the annular groove 73, the lead sleeve 71 can be limited, thereby avoiding the shaking of the lead sleeve 71 when moving, and improving the stability of the lead sleeve 71.

[0029] refer to Figure 1 The inside of the annular groove 73 is fixedly connected with a rubber sleeve 8, and the rubber sleeve 8 is sleeved on the surface of the lead sleeve 71.

[0030] As a technical optimization solution of the present invention, by providing the rubber sleeve 8, the friction between the lead sleeve 71 and the annular groove 73 can be increased, thereby avoiding the phenomenon that the lead sleeve 71 and the nozzle 3 are prone to rotation, and improving the stability of the nozzle 3.

[0031] refer to Figure 1 Both sides of the lead sleeve 71 are provided with oblique openings 9 , and the width of the inner wall of the oblique openings 9 is smaller than the wall thickness of the lead sleeve 71 .

[0032] As a technical optimization solution of the present invention, by providing the oblique opening 9, the air supply pipe 74 can blow the air on the surface of the lead sleeve 71, thereby increasing the air flow speed on the surface of the lead sleeve 71.

[0033] refer to Figure 3 The maximum diameter of the adjusting cone 5 is smaller than the minimum inner diameter of the venturi 2, and the pull plates 10 are fixedly connected to both sides of the lead sleeve 71.

[0034] As a technical optimization solution of the present invention, by providing a pull plate 10, the friction between the user's hand skin and the nozzle 3 can be increased, making it easier for the user to rotate the nozzle 3 and avoiding the user's hand from sliding on the surface of the nozzle 3, resulting in the inability to effectively rotate the nozzle 3.

[0035] refer to Figure 1 The number of through holes 6 is greater than six, and the through holes 6 are evenly distributed. The top of the adjusting cone 5 is fixedly connected with a T-shaped rod 11, and the tops of both sides of the T-shaped rod 11 are fixedly connected to the inside of the supporting tube 4.

[0036] As a technical optimization solution of the present invention, by providing the T-shaped rod 11, the adjusting cone 5 can be positioned, thereby avoiding the phenomenon that the connection between the adjusting cone 5 and the supporting tube 4 is easily damaged, and improving the stability of the adjusting cone 5.

[0037] The working principle and use process of the present invention are as follows: when in use, the user first injects the treated liquid carbon dioxide into the interior of the venturi 2, and then rotates the nozzle 3 so that the nozzle 3 drives the support tube 4 to move downward through the cooperation of the threads, and the support tube 4 drives the adjusting cone 5 to be stuck in the minimum inner diameter of the venturi 2, thereby reducing the outflow of liquid carbon dioxide and increasing the outflow speed of liquid carbon dioxide. The efficiency of forming a solid state through the adjusted carbon dioxide is higher, and after forming a solid state, it is sprayed out from the top of the nozzle 3. Since the temperature of carbon dioxide drops sharply after changing from liquid to solid, the nozzle 3 will become cold, thereby forming condensed water on the nozzle 3. Since the thermal conductivity of lead is low, the lead sleeve 1 71 and the lead sleeve 2 72 will protect the nozzle 3, reduce the thermal conductivity efficiency, and prevent the heat of normal temperature air from contacting the nozzle 3. At the same time, compressed air will be injected into the interior of the lead sleeve 1 71 and the lead sleeve 2 72 through the air supply pipe 74 and take away the cold generated by the nozzle 3, thereby reducing the generation of condensed water on the surface of the nozzle 3, thereby achieving a higher spraying efficiency.

[0038] To sum up: the carbon dioxide cleaning nozzle, in which the nozzle 3 drives the adjusting cone 5 through the supporting tube 4 to be stuck into the minimum inner diameter of the venturi tube 2, reduces the outflow of liquid carbon dioxide, increases the outflow speed of liquid carbon dioxide, and makes the efficiency of liquid carbon dioxide to form a solid state higher. The air supply mechanism 7 then insulates the surface and interior of the nozzle 3 to reduce the cold amount on the surface of the nozzle 3 and the generation of condensed water on the surface of the nozzle 3, thereby having the advantage of higher spraying efficiency. It solves the problem that the interior of the existing cleaning nozzle only throttles the carbon dioxide liquid through the venturi tube and does not have a certain adjustment structure, resulting in the same spray speed of the carbon dioxide liquid, which is not convenient for spraying when the spraying area is small and the spraying efficiency is low. At the same time, it avoids the problem that condensed water is easy to appear on the surface of the nozzle.
