[0030] The following is a detailed description of a multi-nozzle, multi-channel spray gun according to the present invention, with reference to the accompanying drawings.

[0031] Combined with appendix Figure 1-11 The specific implementation process of this utility model of a multi-nozzle, multi-channel spray gun is as follows:

[0032] Example 1

[0033] A multi-nozzle, multi-channel spray gun includes a main channel 1, a spray gun base 2, and a drive and steering mechanism. The main channel 1 is used to transport water flow, and its front end and / or rear end are equipped with multi-channel nozzles 3 to achieve multi-angle and multi-range spraying. The rear end of the main channel 1 is connected to the spray gun base 2, which serves as the main support part of the spray gun and provides a foundation for the installation and connection of various components.

[0034] The drive steering mechanism includes a drive nozzle 4 and a steering mechanism. The rear end of the drive nozzle 4 is connected to the spray gun seat 2, and the front end faces the steering mechanism, which is used to introduce water flow into the steering mechanism and drive it to rotate. The steering mechanism is fixedly connected to the main water channel 1, and its rear end is connected to the spray gun seat 2. The rotation of the steering mechanism drives the main water channel 1 and the multi-channel nozzle 3 to adjust the spraying direction.

[0035] The multi-channel sprinkler head 3 includes a water channel connecting pipe 5, a sprinkler water channel 6, and a spray head 7. The water channel connecting pipe 5 connects to the main water channel 1, introducing water flow into the sprinkler water channel 6. Several sprinkler water channels 6 are provided, all connected to the water channel connecting pipe 5, to achieve simultaneous or independent spraying. The spray head 7 is located at the end of the sprinkler water channel 6 and is used to spray water out in a specific shape and angle.

[0036] Depending on actual needs, the multi-channel sprinkler head 3 can be installed at the front end of the main waterway 1, which can directly expand the spraying range at the front end. In this case, the number of sprinkler channels 6 on the multi-channel sprinkler head 3 can be one or more, with additional... Figure 1 , 3 Examples of spray gun structures with three and four nozzle channels 6 are shown respectively. The multi-channel nozzle 3 can be oriented in any direction, and it can be fixedly connected to the main channel 1 or detachably connected, such as by threaded connection; all of these should be within the scope of protection of this application.

[0037] The spray gun base 2 is provided with an auxiliary water outlet channel 9 that communicates with its interior. There are several auxiliary water outlet channels 9, and each auxiliary water outlet channel 9 is connected to a steerable nozzle 10 at its end, which further increases the spraying flexibility and range of the spray gun.

[0038] A steering switch 11 is provided at the connection between the steering mechanism and the base to control the engagement and disengagement of the steering mechanism. The steering switch 11 includes a base connecting sleeve 12, a steering worm 13, a worm sleeve 14, a switch handle 15, and an eccentric shaft 16. The base connecting sleeve 12 is fixed to one side of the base, and the worm sleeve 14 is disposed inside the base connecting sleeve 12 and rotatably connected to it. The steering worm 13 is disposed inside the worm sleeve 14, and one end of the eccentric shaft 16 is eccentrically connected to the steering worm 13, while the other end is connected to the shaft of the drive worm 20 inside the steering mechanism. A switching groove 17 is provided on the base connecting sleeve 12, and the switch handle 15 is located within the switching groove 17 and passes through the worm sleeve 14 to connect to the steering worm 13. Pulling the switch handle 15 to slide within the switching groove 17 can cause the steering worm 13 to engage or disengage with the steering gear inside the spray gun holder 2, thereby controlling the steering function of the steering mechanism.

[0039] The steering mechanism includes a waterproof gearbox 18, a drive sleeve 19, and a drive worm gear 20. One end of the drive sleeve 19 is connected to the base connecting sleeve 12, and the other end is connected to the waterproof gearbox 18. The waterproof gearbox 18 is connected to and fixed to the main waterway 1 via a steering limit bracket 21, and the turbine 29 at the upper end of the waterproof gearbox 18 is rotatably positioned in the water spray direction of the drive nozzle 4. The drive worm gear 20 is rotatably disposed within the drive sleeve 19, with one end connected to the power output end of the waterproof gearbox 18 and the other end connected to the eccentric shaft 16. Through the transmission action of the waterproof gearbox 18, smooth steering of the steering mechanism can be achieved.

[0040] The waterproof gearbox 18 includes a housing 22, inside which is a speed-regulating gear set 23 for adjusting steering speed. A speed-regulating switch 24, meshing with the speed-regulating gear set 23, is located on the side wall of the housing 22, allowing the user to adjust the steering speed according to actual needs. The power input end of the speed-regulating gear set 23 is connected to a turbine 29 via a rotating shaft, and the power output end is connected to a drive worm gear 20. A waterproof sleeve 25, fitted over the rotating shaft, prevents water from entering the housing 22, ensuring the sealing performance of the waterproof gearbox 18.

[0041] The steering limit bracket 21 includes a gearbox connecting plate 26, a limiting cavity 27, and a tension adjustment seat 28. The gearbox connecting plate 26 is detachably connected to the waterproof gearbox 18 for easy maintenance and replacement. The limiting cavity 27 is located at the end of the gearbox connecting plate 26 and is used to limit the rotation range of the steering mechanism. The tension adjustment seat 28 is located on top of the limiting cavity 27 and fits over the outside of the main waterway 1. The tension can be adjusted by adjusting the tension bolts, thereby adjusting the fixing tightness and rotational flexibility of the steering mechanism.

[0042] Example 2

[0043] Compared with Example 1, the difference in this example is:

[0044] A multi-channel nozzle 3 is located at the rear of the main waterway 1. A detachable nozzle 8 can be installed at the front end of the main waterway 1 to meet different spraying needs. Similarly, a multi-channel nozzle 3 can also be installed at the front end of the main waterway 1. The multi-channel nozzle 3 can be oriented in any direction and can be fixedly or detachably connected to the main waterway 1, such as through a threaded connection. All of these should be within the scope of protection of this application.

[0045] In this embodiment, since a multi-channel nozzle 3 is provided at the rear of the main waterway 1, an auxiliary water outlet channel 9 may not be provided on the spray gun seat 2.

[0046] To meet the needs of some users, an auxiliary water outlet channel 9 can also be set on the spray gun base 2. In this case, the number of auxiliary water outlet channels 9 should not be too many, and one is generally sufficient. If the user uses a water pump with higher power to connect the spray gun of this utility model, the number of auxiliary water outlet channels 9 can also be increased accordingly, and several can be set. Each auxiliary water outlet channel 9 is connected to a steerable nozzle 10 at its end, further increasing the spraying flexibility and range of the spray gun.

[0047] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
