[0030] Insert one end of the nozzle body 3 into the connector 2, and insert one end of the nozzle pipe 1 into the connector 2 and abut against the nozzle body 3, and then firmly connect the three. The cleaning liquid in the nozzle pipe 1 finally enters the nozzle body 3 from the position of the through hole 202.

[0031] The nozzle body 3 includes a drum-shaped airbag tensioner 303 located outside the joint 2, a trumpet ring 301 is fixed to the end of the drum-shaped airbag tensioner 303 away from the joint 2, a trumpet mouth 3012 is opened in the trumpet ring 301, and a triangular ring 302 with a triangular cross-section is fixed to the inner wall of the trumpet ring 301 on one side of the trumpet mouth 3012, a connecting ring 304 is fixed to the end of the drum-shaped airbag tensioner 303 away from the trumpet mouth 3012, a flange 305 is fixed to the end of the connecting ring 304 away from the drum-shaped airbag tensioner 303, the flange 305 is located in the inner cavity of the joint 2, and the connecting ring 304 is located in the through hole 202;

The drum-shaped airbag tensioner 303 is located outside the joint 2. When connecting the glass tube body 4, it is inserted from the outside of the bell mouth 3012, and the end of the glass tube body 4 enters the drum-shaped airbag tensioner 303 and abuts against the pipe head 104 at the end of the nozzle 1, so that the cleaning water can enter the glass tube body 4 for cleaning. At the same time, the triangular ring 302 will wrap around the outer periphery of the glass tube body 4 to achieve a certain sealing treatment;

[0033] The outer side of the bell mouth 3012 is fixed with a fixing ring 3011 distributed in a circular array, and the outer end surface of the joint 2 outside the through hole 202 is fixed with support rods 5 distributed in a circular array, and one end of the support rod 5 away from the joint 2 is fixedly connected to the corresponding support rod 5;

[0034] The outside of the bell mouth 3012 is fixed to the support rod 5 by a fixing ring 3011. Since the bell mouth 3012 and the drum-shaped airbag tensioner 303 are both made of soft materials, they are easily deformed when inserted into the glass tube body 4. After being supported by the support rod 5, when the glass tube is inserted from the outside into the bell mouth 3012, the bell mouth 3012 will not be squeezed and deformed toward the drum-shaped airbag tensioner 303, so the nozzle body 3 can have a longer service life.

[0035] According to the cleaning process requirements of the automatic cleaning line, the cleaning process will be exposed to a large amount of corrosive cleaning agents. Combined with the fragile properties of the glass tube itself, the nozzle is required to have good flexibility, resistance to bending and cracking, wear resistance, weather resistance, heat resistance, chemical corrosion resistance and other properties during the cleaning process. Therefore, the nozzle body 3 is made of Hypalon material as a whole. Hypalon is a chlorinated elastomer. Especially in harsh environments, Hypalon material exhibits long life and stability.

[0036] A through pipe head 104 is fixed on one end face of the nozzle 1 extending into the joint 2, and a flange 305 is located between the one end face of the nozzle 1 extending into the joint 2 and the inner end face of the joint 2;

The pipe head 104 enters the through hole 202 but does not extend out of the through hole 202. The end of the pipe head 104 away from the nozzle 1 is flush with the outer end surface of the joint 2. The nozzle 1 is also provided with a through flow channel 101, and the flow channel 101 is equal to the inner diameter of the pipe head 104.

[0039] When installing the nozzle body 3, extend its flange 305 into the joint 2 and fit closely against the inner wall of the joint 2. The position of the connecting ring 304 matches the position of the through hole 202 of the joint 2. Then extend the drum-shaped airbag tensioner 303 and the bell mouth 3012 out of the joint 2. Then insert the nozzle 1 into the joint 2 for connection, while abutting against the flange 305 to keep it stable. The pipe head 104 at the end of the nozzle 1 will extend into the inner cavity of the flange 305 and the connecting ring 304, thereby connecting the inner cavity of the nozzle body 3 with the flow channel 101 in the nozzle 1 to facilitate the transportation of the cleaning liquid.

[0040] A glass tube body 4 is inserted into the drum-shaped airbag tensioner 303 and the bell mouth 3012, and one end of the glass tube body 4 extending into the drum-shaped airbag tensioner 303 contacts the tube head 104, so that the cleaning liquid in the nozzle 1 is directly input into the glass tube. The inner diameter of the glass tube body 4 is smaller than the inner diameter of the flow channel 101; the high-pressure cleaning liquid generated by the equipment can fully rinse the inner cavity of the glass tube.

[0041] The large inner diameter port of the bell mouth 3012 is located on a side away from the drum-shaped airbag tensioner 303, and part of the triangular ring 302 is located inside the drum-shaped airbag tensioner 303, and the inner wall of the triangular ring 302 contacts the outer wall of the glass tube body 4;

[0042] When the pressure of the cleaning liquid passing through the nozzle body 3 is greater, part of the cleaning liquid enters the drum-shaped airbag tensioner 303 and impacts the outside of the triangular ring 302. At this time, the drum-shaped airbag tensioner 303 is pressurized and tightened, and the triangular ring 302 is also under pressure, so that it is pressed more firmly on the outer wall of the glass tube body 4, and the sealing and wrapping performance is better.

[0043] The end of the nozzle 1 extending into the connector 2 is provided with an external thread 102, and the inner wall of the connector 2 is provided with a thread groove 204, and the nozzle 1 is fixed to the connector 2 by screwing the external thread 102 and the thread groove 204;

[0044] The end of the nozzle 1 is initially fixed to the joint 2 by screwing the external thread 102 and the thread groove 204 .

[0045] The end surface of the nozzle 1 extending into the joint 2 is provided with screw holes 103 distributed in a circular array, and the end of the joint 2 outside the through hole 202 is provided with screw holes 203 distributed in a circular array, and the bolts 201 are screwed into the screw holes 203, and the tail ends of the bolts 201 pass through the flange 305 and then screwed into the corresponding screw holes 103;

[0046] After the nozzle 1 and the joint 2 are initially fixed, the bolt 201 is screwed into the outside of the joint 2, and the bolt 201 is screwed into the second screw hole 203 in turn, passes through the flange 305, and is screwed into the first screw hole 103 to achieve a fixed connection between the nozzle 1, the joint 2 and the nozzle body 3, thereby increasing stability, avoiding loosening of the nozzle 1 and the joint 2, and avoiding the problem of insufficiently stable installation of the nozzle body 3.

[0047] The specific working principle of the utility model is as follows: first, install the nozzle body 3, extend its flange 305 into the joint 2, and close to the inner wall of the joint 2, the position of the connecting ring 304 is matched with the position of the through hole 202 of the joint 2, and then extend the drum-shaped airbag tightening member 303 and the bell mouth 3012 out of the joint 2, and then insert the nozzle 1 into the joint 2 for connection, and the end of the nozzle 1 is screwed with the thread groove 204 through the external thread 102 to achieve preliminary fixation with the joint 2. At this time, the nozzle head 1 at the end of the nozzle 1 is 04 will extend into the inner cavity of the flange 305 and the connecting ring 304, thereby connecting the inner cavity of the nozzle body 3 with the flow channel 101 in the nozzle 1, and the drum-shaped airbag tensioner 303 and the bell mouth 3012 are located outside the joint 2, and then the bolt 201 is screwed into the outer joint 2, and the bolt 201 is screwed into the screw hole 203 in turn, passes through the flange 305, and is screwed into the screw hole 103 to achieve the fixed connection between the nozzle 1, the joint 2 and the nozzle body 3. Subsequently, when the glass tube body 4 is connected, it is pulled out from the bell mouth 3 012 is inserted from the outside, the end of the glass tube body 4 enters the drum-shaped airbag tightening member 303, and abuts against the tube head 104 at the end of the nozzle 1. The triangular ring 302 will wrap around the outer periphery of the glass tube body 4 to achieve a certain sealing treatment. During this process, the outside of the bell mouth 3012 is fixed to the support rod 5 by the fixing ring 3011. When the glass tube is inserted from the outside to the inside of the bell mouth 3012, the bell mouth 3012 will not be squeezed and deformed toward the drum-shaped airbag tightening member 303. The cleaning liquid is then input into the nozzle 1. The cleaning agent with a certain pressure enters the inner cavity of the glass tube body 4 through the nozzle body 3. When the cleaning liquid pressure through the nozzle body 3 is greater, part of the cleaning liquid enters the drum-shaped airbag tensioner 303 and impacts the outside of the triangular ring 302. At this time, the drum-shaped airbag tensioner 303 is pressurized and tightened, and the triangular ring 302 is also under pressure, so that it is more firmly pressed on the outer wall of the glass tube body 4, with good sealing and wrapping performance, and the main part of the cleaning liquid is rushed into the glass tube body 4 for flushing.
