DETAILED DESCRIPTION

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 This utility model provides a technical solution: a high-pressure ammonia spraying device, including a spray gun 1, a nozzle 2 and a connecting pipe 3 mounted on the spray gun 1 body, both connected to the spray gun 1. A first connector 4 is welded to the bottom end of the connecting pipe 3, a second thread 401 is formed on the inner wall of the first connector 4, a second connector 5 is provided at the bottom end of the first connector 4, and a third thread 501 adapted to the second thread 401 is formed on the outer wall of the second connector 5. The first connector 4 and the second connector 5 are threadedly connected to facilitate the installation and disassembly of the first connector 4 and the second connector 5. A first thread 301 is formed on the inner wall of the connecting pipe 3, and a filter connecting post 7 is disposed in the cavity formed by the first connector 4 and the second connector 5. A fourth thread 701 adapted to the first thread 301 is formed on the surface of the filter connecting post 7. The connecting pipe 3 and the filter connecting post 7 are threadedly connected to facilitate the quick installation and disassembly of the filter connecting post 7 and the connecting pipe 3. The filter assembly is connected to one end of the filter connection column 7 and is used to filter impurities in the ammonia water.

[0025] The filter assembly includes a filter 8 welded to the end of the filter connecting post 7. A placement groove 801 is formed on one side wall of the filter 8 near the second connecting head 5. A filter screen 9 is disposed in the inner cavity of the filter 8. A connecting block 10 is welded to the circumferential side wall of the filter screen 9. The connecting block 10 is inserted into the groove cavity of the placement groove 801 to facilitate the installation and removal of the filter screen 9. A positioning hole 1001 is formed on the surface of the connecting block 10. The filter assembly also includes a groove 802 formed on one side wall of the filter 8. A positioning rod 803 is disposed in the inner cavity of the groove 802. One end of the positioning rod 803 passes through the groove cavity wall of the groove 802 and is inserted into the cavity of the positioning hole 1001. The other end of the positioning rod 803 extends to the outside of the filter 8. The purpose of this is to position the connecting block 10, thereby positioning and fixing the filter screen 9, so that it is installed in the filter 8. A lever 806 is welded to the end of the positioning rod 803 away from the connecting block 10. This lever 806 facilitates the movement of the positioning rod 803. A movable plate 804 is welded to the surface of the positioning rod 803 within the groove 802. A spring 805 is fitted onto the surface of the positioning rod 803 on the side of the movable plate 804 away from the connecting block 10. This spring 805 compresses the spring 805 when the positioning rod 803 moves away from the filter screen 9, i.e., when the positioning rod 803 is withdrawn from the positioning hole 1001. This allows the movable plate 804 to compress the spring 805, so that when the lever 806 is released, the spring 805 automatically resets the positioning rod 803. A supply pipe 6 is connected to the surface of the second connector 5 to facilitate the introduction of ammonia into the ammonia spraying device. A central guide hole 201 is provided at the axis of the nozzle 2. The outer circumference of the central guide hole 201 is provided with external guide holes 202 on the nozzle 2. There are six external guide holes 202 arranged in a circumferential array. By adding six external guide holes 202 and one central guide hole 201 inside the nozzle 2, the high-pressure ammonia water enters the nozzle 2 and is diverted after passing through the six external guide holes 202 and one central guide hole 201, which increases the flow rate of ammonia water into the nozzle 2, improves the spraying effect, and makes the sprayed high-pressure ammonia water uniform and has a wide coverage.

[0026] After entering the cavity formed by the first connector 4 and the second connector 5 through the supply pipe 6, it must pass through the filter 8 and its internal filter screen 9 before entering the connecting pipe 3 through the filter connecting column 7, and then through the connecting pipe 3 into the spray gun 1, and finally sprayed out by the nozzle 2. Impurities in the ammonia water flowing through the filter screen 9 are filtered out by the filter screen 9, thus avoiding the clogging of the nozzle 2 after long-term use. In order to avoid excessive accumulation of impurities on the surface of the filter screen 9 after long-term use, it can be removed from the end of the first connector 4 by screwing on the second connector 5, and then removed from the end of the connecting pipe 3 by screwing on the filter connecting column 7. Then, by moving the toggle block 806, the positioning rod 803 can be pulled out from the positioning hole 1001, and the filter screen 9 can be removed for cleaning.
