The nozzle 111 is a flat round mouth, similar to an ellipse, and is used to control the spray shape of the dry ice spray. Specifically, the inner diameter of the nozzle inlet end 112 is larger than the inner diameter of the nozzle 111, that is, the nozzle body 11 is a centralized spraying structure, similar to a wedge-shaped mouth, which can concentrate the dry ice entering from the nozzle inlet end 112 and spray it out from the nozzle 111. This wedge-shaped mouth can speed up the spraying speed.

[0036] The ice crushing section 12 is connected to the nozzle body 11 , and specifically, the ice crushing section 12 is connected to the nozzle inlet end 112 .

[0037] One end of the ice crushing section 12 is an ice inlet 122, and the other end is an ice crushing port 121. The ice crushing section 12 is connected to the nozzle connection end 112 through the ice crushing port 121. That is, the dry ice introduced through the ice inlet 122 of the ice crushing section 12 is crushed once through the ice crushing port 121, and then introduced into the nozzle body 11 through the nozzle connection end 112, and sprayed out through the nozzle 111.

[0038] The ice crushing port 121 may preferably be a slot structure with a plurality of cylindrical holes. Preferably, the diameter of the holes is 3.6-5.5 mm. This makes the dry ice ejected through the holes on the ice crushing port 121 more finely broken and uniform. Specifically, the ice crushing port 121 is a slot structure with a smaller diameter in a direction away from the nozzle inlet end 112, specifically a semi-ellipsoid or hemispherical shape with holes.

Specifically, the rough processing ice crushing rack 123 includes one ice crushing bar or two or more intersecting ice crushing bars.

[0040] Preferably, the rough processing ice crushing rack 123 is composed of two ice crushing bars, and the two vertically intersecting ice crushing bars form a cross ice crushing rack 1231, and a plurality of fan-shaped holes are arranged between the two vertically intersecting ice crushing bars.

[0041] Specifically, the middle of the rough processing ice crushing rack 123 is a cross ice crushing rack 1231. Through the cross design, the dry ice is roughly crushed. The dry ice is first crushed into smaller pieces and crushed once to prevent blockage in the subsequent ice crushing port 121 during the secondary ice crushing, thereby improving the ice crushing efficiency and ice crushing effect.

[0042] Preferably, the cross ice crushing rack 1231 is composed of two vertically intersecting ice crushing strips, and a plurality of fan-shaped holes are left between the two vertically intersecting ice crushing strips. The area of ​​the fan-shaped holes is preferably much larger than the area of ​​the cylindrical holes at the ice crushing port 121, which is conducive to breaking large pieces of dry ice and then roughly crushing the dry ice.

[0043] The external thread of the ice crushing port 121 can be connected to the nozzle connecting end 112 by threading, so that the connection is more stable and can be easily disassembled, cleaned and replaced.

[0044] Preferably, the inner diameter of the ice inlet 122 is greater than or equal to the inner diameter of the ice crushing port 121 , so that the dry ice can be ejected from the holes on the ice crushing port 121 after being squeezed.

[0045] A solder deburring device comprises the above-mentioned solder deburring nozzle device 1 and an ice maker 2, wherein the solder deburring nozzle device 1 is connected to the ice maker 2. Specifically, the ice maker 2 is connected to the solder deburring nozzle device 1 through a connecting pipe 21. More specifically, the ice maker 2 is connected to the inlet of an external spray gun through the connecting pipe 21, and the end of the external spray gun is connected to the solder deburring nozzle device 1.

[0046] Preferably, the ice maker 2 may be provided with a temperature controller and a pressure controller so as to control the temperature of the dry ice and the pressure at which the dry ice is discharged.

Specifically, the inner diameter of the nozzle inlet end 112 is larger than the inner diameter of the nozzle 111, that is, the nozzle body 11 is a centralized spraying structure, similar to a wedge-shaped opening, which can concentrate the dry ice entering from the nozzle inlet end 112 and spray it out from the nozzle 111. This wedge-shaped opening can speed up the spraying speed. The ice crushing section 12 is connected to the nozzle body 11, and specifically, the ice crushing section 12 is connected to the nozzle inlet end 112.

[0050] The nozzle device 1 for removing solder burrs of this embodiment can be used to eject crushed ice to remove burrs on the solder. Specifically, dry ice is introduced from the crushing ice section 12, crushed once by the crushing ice section 12, and then introduced into the nozzle body 11 from the nozzle inlet end 112, and ejected from the nozzle 111 after being squeezed. The ejected dry ice is finely crushed and uniform, and can evenly cover the solder, freezing and removing the burrs on the solder.

[0051] Example 2

[0052] A nozzle device 1 for removing solder burrs, such as Figure 1-3 Compared with Example 1, the ice crushing section 12 is optimized.

The ice crushing section 12 is connected to the nozzle connection end 112 through the ice crushing port 121. That is, the dry ice introduced through the ice inlet 122 of the ice crushing section 12 is crushed once through the ice crushing port 121, and then introduced into the nozzle body 11 through the nozzle connection end 112, and sprayed out through the nozzle 111.

[0054] The ice crushing port 121 may preferably be a slot structure with a plurality of cylindrical holes. Preferably, the diameter of the holes is 3.6-5.5 mm. This makes the dry ice ejected through the holes on the ice crushing port 121 more finely broken and uniform. Specifically, the ice crushing port 121 is a slot structure with a smaller diameter in a direction away from the nozzle inlet end 112, specifically a hemispherical shape with holes.

[0055] The ice crushing port 121 is connected to the nozzle connection end 112 by threads, so that the connection is more stable and can be easily disassembled, cleaned and replaced.

[0056] Preferably, the inner diameter of the ice inlet 122 is greater than or equal to the inner diameter of the ice crushing port 121 , so that the dry ice can be ejected from the holes on the ice crushing port 121 after being squeezed.

Specifically, a cross ice crushing rack 1231 is provided in the middle of the rough processing ice crushing rack 123. Through the cross design, the dry ice is roughly crushed, and the dry ice is first crushed into smaller pieces for a first crushing, so as to prevent the subsequent ice crushing port 121 from being blocked during the second crushing, thereby improving the ice crushing efficiency and ice crushing effect.

[0061] Preferably, the cross ice crushing rack 1231 is composed of two vertically intersecting ice crushing strips, and a plurality of fan-shaped holes are left between the two vertically intersecting ice crushing strips. The area of ​​the fan-shaped holes is preferably much larger than the area of ​​the cylindrical holes at the ice crushing port 121, which is conducive to breaking large pieces of dry ice to perform rough crushing of the dry ice.
