[0033] Reference Figure 1 、 Figure 2 、 Figure 5 , the utility model provides an embodiment: a spray device, including a frame 1, which stabilizes the device and plays a fixing role on the main pipe 13 and the water tank 8. The front end of the frame 1 is fixedly connected to a fixing frame 3, so that the upper end part of the nozzle 2 can be plugged into the fixing frame 3 through the fixing effect. The upper end of the fixing frame 3 is plugged with a nozzle 2. The nozzle 2 is a prior art. The water flow can be sprayed out through the head by connecting the hose 5 at the bottom. The rear end of the nozzle 2 is provided with a button. When the button is pressed, the water flow stops spraying. The front end of the frame 1 is provided with a water outlet mechanism 4. The outlet The water mechanism 4 includes a branch pipe 401, which diverts the water in the main pipe 13 through the branch pipe 401. There are multiple groups of water outlet mechanisms 4, and each water outlet mechanism 4 can be used separately to control a single nozzle 2 to spray water. The nozzle 2 is linearly connected to the branch pipe 401 through a hose 5. One end of the hose 5 is fixedly connected to the lower end of the nozzle 2, and the other end of the hose 5 is fixedly connected to the front end of the branch pipe 401, so that the water flows from the branch pipe 401 to the nozzle 2 through the hose 5. The hose 5 is flexible, allowing the user to adjust the position and angle of the nozzle 2 according to actual needs.

[0034] refer to Figure 2-Figure 4The inner wall of the frame 1 is fixedly connected with a main pipe 13, so that water can flow from the main valve 9 through the main pipe 13 to the branch pipe 401 for the water flow transmission effect. The upper end of the main pipe 13 is fixedly connected with a water tank 8, so that water can be stored in the water tank 8. The upper end of the water tank 8 is provided with a pressurizing mechanism, which includes a pressurizing device 7. The pressurizing device 7 at the upper end pressurizes the upper end air in the water tank 8 to pressurize the internal water, so that the pressure of the water flowing out of the nozzle 2 is higher. The intensity of the large spray is higher. By pressurizing, the main valve 9 can be made not to be connected to the water flow, and the water in the device can be discharged by pressurizing. When the main valve 9 is closed and there is enough water in the water tank 8, the device can be used by pressurizing the booster 7 without inputting a water source. The lower end of the booster 7 is fixedly connected to the upper end of the water tank 8, and the left end of the booster 7 is fixedly connected to the ventilation pipe 11, so that the air passes through the ventilation pipe 11 to pressurize the booster 7. The inner wall of the left end of the frame 1 is fixed to the outer wall of the main pipe 13. Fixed connection, the main pipe 13 passes through the left end outer wall of the frame 1, the lower left end of the main pipe 13 is fixedly connected to the right end of the main valve 9, the main valve 9 is a prior art, which can allow water to flow from the main valve 9 into the main pipe 13, or it can be closed to block water from entering, the left end outer wall of the frame 1 is fixedly connected to the right end of the ventilation pipe 11, so that the frame 1 provides a fixing effect for the ventilation pipe 11, the inner wall of the frame 1 is slidably connected with a linkage rod 10, the linkage rod 10 moves laterally in the frame 1 to provide a guide for it, and the linkage rod 10 is fixedly connected to the left end outer wall of the frame 1. The right end is fixedly connected with a handle 6, and the fixedly connected linkage rod 10 can be pulled by the handle 6 to move horizontally. The outer wall of the linkage rod 10 is fixedly connected with a baffle 17, and the baffle 17 is elastically connected to the frame 1 through a spring A18. One end of the spring A18 is fixedly connected to the outer wall of the baffle 17, and the other end of the spring A18 is fixedly connected to the inner wall of the frame 1. The spring A18 fixes the linkage rod 10 without being affected by external force, and different effects will be produced when forces in different directions are applied to the handle 6.

[0035] refer to Figure 3 、 Figure 5The left end of the main pipe 13 is fixedly connected to the pressure relief pipe 12. The inner wall of the pressure relief pipe 12 is slidably connected to a blocking bead 14. The blocking bead 14 is elastically connected to the pressure relief pipe 12 via a spring B15. One end of the spring B15 is fixedly connected to the blocking bead 14. The other end of the spring B15 is fixedly connected to the inner wall of the pressure relief pipe 12. The rear end of the pressure relief pipe 12 is fixedly connected to the outer wall of the water storage tank 8. When the handle 403 on the water outlet mechanism 4 is closed, the water flow will instantly squeeze the main pipe 13. This pressure is transferred to the blocking bead 14 through the pressure relief pipe 12. When the water flow squeezes the blocking bead 14, it compresses the spring B15. At this time, the blocking bead 14 no longer blocks the water flow. The pressure relief pipe 12 is connected to the water storage tank 8, allowing the water to flow into the water storage tank 8 through the pressure relief pipe 12. When the water pressure is restored, the spring B15 will reset the blocking bead 14 to prevent the water from passing through the pressure relief pipe 12.

[0036] refer to Figure 3 、 Figure 6 The inner wall of the branch pipe 401 is rotatably connected to a water control shaft 402, and a channel is provided in the water control shaft 402 to allow water to flow through. When the water control shaft 402 rotates, the channel is not connected to the pipe and will block the flow of water. The upper end of the water control shaft 402 is fixedly connected to a handle 403, and the rotation of the handle 403 drives the water control shaft 402 to rotate. The lower end of the water control shaft 402 is fixedly connected to a steering shaft 404, and the steering shaft 404 can also make the water control shaft 402 rotate. The bottom end of the handle 403 is rotatably connected to the inner wall of the branch pipe 401, and the upper end of the steering shaft 404 is rotatably connected to the inner wall of the branch pipe 401. The handle 403 and the steering shaft 404 pass through the branch pipe 401 and are connected to the water control shaft 402, and The connection is sealed to prevent water from flowing out. The outer wall of the linkage rod 10 is fixedly connected to the concave block 16. Pulling the linkage rod 10 will drive the concave block 16 to move. The outer wall of the bottom end of the steering shaft 404 contacts the outer wall of the concave block 16. The concave block 16 is arc-shaped at the contact point between the concave block 16 and the steering shaft 404. The steering shaft 404 is circular. When the concave block 16 moves, the steering shaft 404 will rotate clockwise through the arc surface protruding from the bottom. When the front end concave block 16 pushes the steering shaft 404 to rotate backward, the water control shaft 402 will be closed. When the rear end concave block 16 pushes the steering shaft 404 to rotate counterclockwise, the water control shaft 402 will be opened. When the linkage rod 10 is not moved, the concave block 16 will not affect the steering shaft 404.

[0037] Working principle: When the spray device needs to be used, take out the spray head 2 from the fixing frame 3, turn the handle 403 to turn on the switch, and then you can use a single group of spray devices. When pulling the handle 6, pull it backward to make the concave block 16 connected to the linkage rod 10 drive each group of steering shafts 404 to rotate clockwise, so that all the water control shafts 402 on the water outlet mechanisms 4 are closed. When pushing the handle 6 forward, the rear end concave block 16 drives each group of steering shafts 404 to rotate counterclockwise, so that the upper water control shafts 402 of all water outlet mechanisms 4 are opened. If the water control shaft 402 is already opened, the movement of the rear end concave block 16 will not contact the steering shaft 404 and will not change its open state. Vice versa, rotating the handle 403 of a group of water outlet mechanisms 4 alone will not affect the linkage rod 10.

[0038] The pressurizer 7 can be used to pressurize the air in the water tank 8, which will also put pressure on the water in the water tank 8. When the spray device is used, the water pressure is stronger, and the water output by the nozzle 2 can be sprayed farther and stronger. When there is enough water in the water tank 8, close the main valve 9 to allow the pressurizer 7 to continuously pressurize the water tank 8, so that the device can be used alone outdoors or in scenes where it is not connected to other water sources. When the outside temperature is very low, the water in the device needs to be drained. Turn on all switches and turn on the pressurizer 7 to drain the water in the device through air pressure squeezing.

[0039] When the device is used and the switch is turned off at the same time, a strong water hammer effect will be generated to cause pressure on the main pipe 13. At this time, the blocking bead 14 inside the pressure relief pipe 12 will be squeezed due to the excessive water pressure. At this time, the water pressure is greater than the thrust of the spring B15. The blocking bead 14 no longer blocks the water flow, allowing part of the water to flow into the water tank 8. When the water pressure returns to normal level, the spring B15 will reset the blocking bead 14 to block the water from passing through. By releasing part of the water, the pressure in the main pipe 13 is reduced, which is beneficial to extending the life of the device.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
