[0023] The mouth body 10 is provided with a limiting groove 11 and a connecting groove 12 which are communicated with each other at both ends, the side wall of the limiting groove 11 is inclined to form a first inclined surface 111 near one end of the connecting groove 12, the flow guide block 30 is provided with a flow guide hole 31, one end of the flow guide block 30 abuts on the first inclined surface 111, and the other end abuts on the threaded sleeve 40, and the connecting end of the threaded sleeve 40 is connected in the connecting groove 12 through threaded rotation.

[0024] When the nozzle is used, the cooling water passes through the threaded sleeve 40 and the flow guide hole 31 to enter the plurality of spray ports 21, and under the guidance of the second guide surface 212, the cooling water flows into the middle part of the spray port 21. According to the principle of Bernoulli's law, the flow space of the cooling water in the plurality of spray ports 21 becomes smaller, which causes the flow rate to increase and the pressure to decrease. When the cooling water flows to the first guide surface 211, the cooling water is sprayed to the surrounding under the guidance of the first guide surface 211 and the pressure, forming a certain atomization effect and improving the atomization amount of the nozzle spray.

[0025] With reference to Figure 1 , the two sides of the flow guide hole 31 are inclined to form a third guide surface 311 and a fourth guide surface 312.

[0026] When the cooling water passes through the threaded sleeve 40 to enter the flow guide hole 31, the cooling water flows into the middle part of the flow guide hole 31 under the guidance of the fourth guide surface 312. According to the principle of Bernoulli's law, the flow space of the cooling water in the middle part of the flow guide hole 31 becomes smaller, which causes the flow rate to increase and the pressure to decrease. When the cooling water flows to the third guide surface 311, the cooling water is sprayed to the surrounding under the guidance of the third guide surface 311 and the pressure, performing preliminary atomization and enabling the plurality of spray ports 21 to fully contact the cooling water for further atomization, thereby improving the atomization effect.

[0028] The flow guide block 30 is elastically arranged, the second inclined surface 32 is tightly attached to the first inclined surface 111, forming a sealing effect, so that the cooling water can only pass through the flow guide hole 31 to enter the spray port 21, thereby ensuring the preliminary atomization effect of the cooling water.

[0029] With reference to Figures 1-3 , the fixed end of the threaded sleeve 40 is provided with a threaded groove 42.

[0030] When the threaded sleeve 40 is installed, it can be installed at the corresponding position through the threaded groove 42, so that it is convenient to disassemble and maintain in the later period.
