Description

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of horticultural irrigation tools, and in particular, relates to a spray gun with convenient and quick water discharge.BACKGROUND

[0002] A horticultural spray gun is a device used for horticultural work, usually connected to a faucet or hose, for irrigating plants, cleaning gardens, spraying fertilizers or chemicals, and so on. The spray pattern, spray intensity and spray range are usually adjustable to meet the water demand of different kinds of plants and the requirements of horticultural work. In the process of social development, the emergence and popularization of horticultural spray guns reflect people's concern for horticulture, agriculture and the environment, as well as technological advancements and changes in lifestyles. Prior to the agricultural revolution, people relied mainly on hand watering or natural precipitation to meet the water needs of crops. This approach was inefficient and susceptible to climatic and seasonal constraints, resulting in unstable yields. With the acceleration of urbanization and industrialization, the demand for horticulture in densely populated cities and peri-urban areas has been increasing. The emergence of horticultural spray guns meets the needs of urban residents for landscaping and greening public spaces, and has become an important tool for urban gardeners.

[0003] Existing horticultural spray guns usually require fine-tuning to control the water discharge when in use, and fine-tuning the water discharge usually requires the user to rotate and adjust several times, which is relatively cumbersome to operate, especially for unfamiliar or inexperienced users, it may take more time and energy to master the correct operation method. Due to the complex structure of the spray gun with fine-tuning water discharge, the maintenance and cleaning are relatively difficult. Regular cleaning and maintenance are required, otherwise problems such as blockage or water leakage are prone to occur, which affects the use effect. Document D1 (US 3294362 A) discloses a gun for dispensing fluid materials under pressure, comprising a body defining a material chamber having an inlet and an outlet and a material supply passage communicatively coupled with said inlet, valve means operable in the chamber to open and close said outlet and including a reciprocable rod projecting axially into the chamber having a U-shaped yoke at the rear end thereof and a hollow balanced closure piston mounted on the rod and adapted to sealingly seat within said outlet, a guide member fixedly mounted encircling said valve rod and projecting guidably into said piston, spring means operably coupled to said valve means yieldably urging the latter to a normally closed position, and trigger means pivotally mounted on said gun body having a laterally projecting pin fixed thereto embraced by said valve rod yoke whereby pivotal movement of said trigger imparting arcuate movement to said pin produces a substantially axial force on said valve rod to shift the valve to its open position, said piston exhibiting a relatively small effective area exposed to pressure of said material in the chamber to enable actuation of said valve means opening said outlet with a minimum force exerted on said trigger.

[0004] In conclusion, the existing horticultural spray gun has the problem that the operation is cumbersome and the water cannot be quickly discharged.SUMMARY

[0020] In a further aspect, the following operation illustrates an example method for controlling the spray gun using the spray gun described herein.

[0021] When the spray gun with convenient and quick water discharge is used, a water flow stays in the water inlet pipe 12 due to the blocking of the stopper 144, and when the nozzle 13 needs to spray water, a lever 15 is held to rotate a knob 141, the knob 141 drives a connecting shaft 143 to rotate, and the connecting shaft 143 simultaneously drives a vertical baffle plate 142, a stopper 144 and a bump 16 to rotate. As the stopper 144 and the bump 16 rotate tightly against an inner wall of the water spray gun body 10 to expose a water outlet of the water inlet pipe 12, the water flow flows into the water spray gun body 10 from the water inlet pipe 12, and as the vertical baffle plate 142 and a water inlet of the nozzle 13 are consistent in size, water does not flow out of the water spray gun body 10. Then, the handle 11 is moved such that a bottom end of the handle 11 approaches towards the water inlet pipe 12, and as one end of the handle 11 is movably connected to the water spray gun body 10, a top end of the handle 11 moves in a direction away from the water inlet pipe 12, driving the knob 141 to move backward, the knob 141 drives the connecting shaft 143 and the vertical baffle plate 142 to slide inside the water spray gun body 10, and a gap appears between the vertical baffle plate 142 and a water inlet of the nozzle 13, and the water flow flows from the water spray gun body 10 to the nozzle 13 through the gap to be eventually sprayed out.

[0022] When the spray gun with convenient and quick water discharge is to be stopped, the handle 11 is released to reset the control assembly 14, and the vertical baffle plate 142 blocks the water inlet of the nozzle 13, by which the water flow of the water spray gun body 10 cannot flow out; the knob 141 is rotated to drive the stopper 144 to rotate and return to position, and the stopper 144 blocks a water outlet of the water inlet pipe 12, and the water in the water inlet pipe 12 cannot enter the water spray gun body 10; and repeatedly moving the handle 11 can drain the water from the spray gun body 10.

[0023] In the above technical solution, the control assembly 14 includes the knob 141, the vertical baffle plate 142, the connecting shaft 143 and the stopper 144, the knob 141 is fixedly connected to one end of the connecting shaft 143, the connecting shaft 143 passes through the handle 11 and the water spray gun body 10 and extends to the interior of the water spray gun body 10, the other end of the connecting shaft 143 is fixedly connected to the vertical baffle plate 142, and the stopper 144 is fixedly connected to a lower part of the vertical baffle plate 142.

[0024] Further, in the above technical solution, the stopper 144 is located directly above the water outlet of the water inlet pipe 12, and the stopper 144 is in contact with an inner wall of the water spray gun body 10.

[0025] Further, in the above technical solution, one end of a bump 16 is fixedly connected to an upper part of the vertical baffle plate 142, the other end of the bump 16 is in contact with the inner wall of the water spray gun body 10, and the size of the vertical baffle plate 142 is consistent with the size of the water inlet of the nozzle 13.

[0026] Further, in the above technical solution, the lever 15 is fixedly connected to the knob 141, and the knob 141 has a round table-shaped structure.

[0027] Further, in the above technical solution, a surface of the stopper 144 in contact with the inner wall of the water spray gun body 10 has an arc-shaped structure, and the stopper 144 is matched with the inner wall of the water spray gun body 10.

[0028] Further, in the above technical solution, a surface of the bump 16 in contact with the inner wall of the water spray gun body 10 has an arc-shaped structure, and the bump 16 is matched with the inner wall of the water spray gun body 10.

[0029] Specifically, the principles of the present disclosure are as follows.

As the stopper 144 and the bump 16 rotate tightly against an inner wall of the water spray gun body 10 to expose a water outlet of the water inlet pipe 12, the water flow flows into the water spray gun body 10 from the water inlet pipe 12, and as the vertical baffle plate 142 and a water inlet of the nozzle 13 are consistent in size, water does not flow out of the water spray gun body 10. Then, the handle 11 is moved such that a bottom end of the handle 11 approaches towards the water inlet pipe 12, and as one end of the handle 11 is movably connected to the water spray gun body 10, a top end of the handle 11 moves in a direction away from the water inlet pipe 12, driving the knob 141 to move backward, the knob 141 drives the connecting shaft 143 and the vertical baffle plate 142 to slide inside the water spray gun body 10, and a gap appears between the vertical baffle plate 142 and a water inlet of the nozzle 13, and the water flow flows from the water spray gun body 10 to the nozzle 13 through the gap to be eventually sprayed out.

[0030] When the spray gun with convenient and quick water discharge is to be stopped, the handle 11 is released to reset the control assembly 14, and the vertical baffle plate 142 blocks the water inlet of the nozzle 13, by which the water flow of the water spray gun body 10 cannot flow out; the knob 141 is rotated to drive the stopper 144 to rotate and return to position, and the stopper 144 blocks a water outlet of the water inlet pipe 12, and the water in the water inlet pipe 12 cannot enter the water spray gun body 10; and repeatedly moving the handle 11 can drain the water from the spray gun body 10.
