Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] As shown in the attached Figures 1 to 3 A multifunctional ammonia water nozzle shown in the figure includes an ammonia water connecting pipe 1. A flange 2 is connected to the bottom of the ammonia water connecting pipe 1. One end of the ammonia water connecting pipe 1 away from the flange 2 is connected to an ammonia water nozzle 3. A limit sealing ring 4 is arranged on the inner wall of the middle part of the ammonia water nozzle 3. A nozzle 5 is embedded at the opening of the ammonia water nozzle 3. Clamping grooves 7 are arranged in an array on the inner wall of the middle part of the ammonia water nozzle 3. A top block 8 is arranged on the inner wall of the clamping groove 7. One end of the top block 8 is connected to an ejector rod 9. The end of the ejector rod 9 away from the top block 8 passes through the ammonia water nozzle 3 and is connected to a pressing block 10. A first spring 11 is sleeved on the outer wall of the ejector rod 9 at the bottom of the pressing block 10. The bottom end of the first spring 11 abuts against the outer wall of the ammonia water nozzle 3. Clamping strips 12 are arranged in an array on the outer wall of the nozzle 5. The clamping strips 12 are embedded in the clamping grooves 7.

[0025] Among them, the limit sealing ring 4 plays a role in limit sealing to prevent ammonia water from leaking from the connection between the nozzle 5 and the ammonia water spray head 3. The nozzle 5 is connected to the ammonia water spray head 3 by fitting the clamping strip 12 into the clamping groove 7. When it is necessary to replace different types of nozzles 5 to meet the requirements, the pressing block 10 can be pressed. The pressing block 10 pushes the ejector rod 9 to translate into the clamping groove 7. The translation of the ejector rod 9 pushes the top block 8 to move, thereby pushing the clamping strip 12 to contract inward. The second spring 13 is compressed and contracted, so that the clamping strip 12 is removed from the clamping groove 7. The nozzle 5 can be pulled out for replacement. During installation, the nozzle 5 is inserted into the ammonia water spray head 3, and the clamping strip 12 is compressed and contracted. When the clamping strip 12 moves to the clamping groove 7, the second spring 13 rebounds to make the clamping strip 12 fit into the clamping groove 7, thus realizing the replacement and installation of the nozzle 5 without tools.

[0026] Embodiment 2

[0027] On the basis of Embodiment 1, the solution in Embodiment 1 is further refined and introduced in combination with the following specific working methods, as Figures 1 to 4 shown, and the details are described below:

[0028] As a preferred implementation manner, one end of the clamping strip 12 is movably connected to the nozzle 5 through a rotating shaft, and a second spring 13 is arranged between the inner wall of one side of the clamping strip 12 and the nozzle 5; further, the clamping strip 12 is movable at the rotating shaft connection, and the second spring 13 is compressed and rebounds.

[0029] As a preferred implementation manner, a sealing ring 6 is connected to one end of the nozzle 5 close to the ammonia water spray head 3, and the sealing ring 6 abuts against the limit sealing ring 4; further, the sealing ring 6 abuts against the limit sealing ring 4 to play a sealing role to prevent leakage at the connection.

[0030] As a preferred implementation manner, a sealing plug 14 is arranged on the side of the clamping strip 12 away from the sealing ring 6, and the sealing plug 14 abuts against the opening of the ammonia water spray head 3; further, the sealing plug 14 also plays a sealing role, and cooperates with the sealing ring 6 and the limit sealing ring 4 to play a double-sealing role.

[0031] As a preferred implementation manner, water spraying inclined openings 15 are arranged at one end of the nozzle 5 away from the ammonia water spray head 3; further, the ammonia water can be diffused and sprayed through the water spraying inclined openings 15.

[0032] As a preferred implementation manner, a movable shaft 16 is connected to the inner wall of one side of the ammonia water spray head 3 through a bearing, and a spiral impeller 17 is key-connected to the outer wall of the middle part of the movable shaft 16; further, the movable shaft 16 can rotate in the ammonia water spray head 3, and the rotation of the movable shaft 16 drives the spiral impeller 17 to rotate.

[0033] As a preferred embodiment, a driving motor 18 is provided on the outer wall of one side of the ammonia water spray head 3, and the output end of the driving motor 18 is connected to the movable shaft 16; further, the driving motor 18 can drive the movable shaft 16 to rotate, and the rotation of the movable shaft 16 drives the spiral impeller 17 to rotate. The rotation of the spiral impeller 17 drives the ammonia water in the spray head 5 to rotate and flow, increasing the spraying speed of the ammonia water, improving the impact force, and enhancing the spraying effect.

[0034] As a preferred embodiment, the sealing plug 14, the limit sealing ring 4 and the sealing ring 6 are all made of rubber material; further, the sealing plug 14, the limit sealing ring 4 and the sealing ring 6 are all made of butyl rubber or ethylene propylene rubber material, which can withstand the erosion of ammonia water and play a good sealing role.

[0035] The working process of the present utility model is as follows: First, the ammonia water connecting pipe 1 is connected to the ammonia water pipe through the flange 2, and the nozzle 5 is connected to the ammonia water spray head 3 by the clamping strip 12 being embedded in the clamping groove 7. When it is necessary to replace different types of nozzles 5 to meet the requirements, the pressing block 10 can be pressed. The pressing block 10 pushes the ejector rod 9 to translate into the clamping groove 7. The translation of the ejector rod 9 pushes the top block 8 to move, thereby pushing the clamping strip 12 to contract inward, and the second spring 13 is compressed and contracted. As a result, the clamping strip 12 is removed from the clamping groove 7, and the nozzle 5 can be pulled out for replacement. During installation, the nozzle 5 is inserted into the ammonia water spray head 3, and the clamping strip 12 is compressed and contracted. When the clamping strip 12 moves to the clamping groove 7, the clamping strip 12 is embedded in the clamping groove 7 through the resilience of the second spring 13, so as to realize the replacement and installation of the nozzle 5 without tools. The driving motor 18 can drive the movable shaft 16 to rotate, the rotation of the movable shaft 16 drives the spiral impeller 17 to rotate, and the rotation of the spiral impeller 17 drives the ammonia water in the spray head 5 to rotate and flow, increasing the spraying speed of the ammonia water, improving the impact force, and enhancing the spraying effect. The above is the working principle of the multifunctional ammonia water nozzle.

[0036] Finally: The above description is only a preferred embodiment of the present utility model and is not used to limit the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
