The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0026] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0027] refer to Figure 1 、 Figure 2 as well as Figure 3 As shown, the faucet with a spray gun according to the embodiment of the present invention includes a faucet body and a spray gun connected to the faucet body, the spray gun includes a spray gun body 110, a spray gun outlet pipe 120 connected to the spray gun body 110, and a spray gun switch 130 connected to the spray gun body 110 for controlling the on and off of the spray gun outlet pipe 120; the faucet body includes a shell 210, a nozzle body 220 connected to the shell 210, and a switch valve 230 connected to the top of the shell 210, and the shell 210 is connected to the inside of the nozzle body 220. The sealing valve core 300 and the flow channel valve core 400, the sealing valve core 300 is connected to the switch valve 230, the flow channel valve core 400 is axially spaced apart with a valve core water inlet hole 410 and a valve core water outlet hole 420, the flow channel valve core 400 is circumferentially provided with a water nozzle outlet channel 430 connected to the water nozzle body 220, the water nozzle outlet channel 430 is connected to the valve core water outlet hole 420, the bottom of the valve core water outlet hole 420 is connected to the spray gun water outlet channel 440, and the spray gun water outlet channel 440 is connected to the spray gun water outlet pipe 120.

[0028] During actual use, through the design of the above-mentioned flow channel valve core 400, when the spray gun switch 130 is pressed, the spray gun water outlet pipe 120 is connected to the outside world. At this time, the residual air pressure in the spray gun water outlet pipe 120 will escape into the outside air. The pressure in the spray gun water outlet pipe 120 is less than the pressure of the nozzle water outlet 430. The direction of water flow passes through the valve core water outlet hole 420 directly through the spray gun water outlet 440 and then through the spray gun water outlet pipe 120 to the spray gun body 110 for ejection. The air diversion is guided to the water diversion hole to realize the water diversion function. There is no need to install any additional water divider or switching valve. The overall structure is simple, the failure rate is low, the replacement is convenient, and the maintenance cost is low.

[0029] In some specific embodiments of the present invention, it may also have the following additional technical features: the valve core water outlet hole 420 includes a first water outlet hole 421 and a second water outlet hole 422 connected in sequence along the water flow direction, and the diameter of the first water outlet hole 421 is larger than the diameter of the second water outlet hole 422.

[0030] In some specific embodiments of the present invention, the following additional technical features may be provided: the first water outlet hole 421 and the second water outlet hole 422 are connected via a diameter-reducing hole 423 .

[0031] Through the above design, the flow rate of water flowing out of the second water outlet 422 is faster. When switching from water outlet of the nozzle to water outlet of the spray gun, the water flows into the spray gun outlet channel 440 faster, thereby reducing the diversion into the water outlet channel 430 of the nozzle.

[0032] In some specific embodiments of the present invention, it may also have the following additional technical features: the nozzle outlet 430 is connected to the second water outlet hole 422, and the connection point between the nozzle outlet 430 and the second water outlet hole 422 is a diversion port 431, and the diversion port 431 is located above the spray gun outlet 440.

[0033] Some specific embodiments of the present invention may also have the following additional technical features: the spray gun water outlet 440 is connected to the bottom of the diversion port 431, and the diameter of the spray gun water outlet 440 is larger than the diameter of the diversion port 431. Specifically, when the water flows from the large diameter to the small diameter, a higher pressure will be generated at the diversion port 431. If the spray gun switch 130 is turned on at this time, the water in the diversion port 431 will flow into the spray gun water outlet 440 with a lower pressure.

[0034] In some specific embodiments of the present invention, it may also have the following additional technical features: the spray gun water outlet 440 includes a first water outlet 441 and a second water outlet 442 which are connected in sequence along the direction of water flow, the first water outlet 441 is connected to the diversion port 431, and the second water outlet 442 is connected to the spray gun water outlet pipe 120, and the diameter of the first water outlet 441 is smaller than the diameter of the second water outlet 442.

[0035] Through the above design, the diameter of the spray gun water outlet 440 gradually increases along the direction of water flow, thereby gradually reducing the pressure of the water flowing through it. When switching from water outlet of the nozzle to water outlet of the spray gun, the high-pressure water flow enters the spray gun water outlet 440 and continues to reduce pressure, making the pressure change of the water flow sprayed from the spray gun water outlet 440 to the spray gun water outlet pipe 120 and then to the spray gun body 110 more obvious and from large to small, thereby making the water flow smoother and the diversion effect better.

[0036] In some specific embodiments of the present invention, the following additional technical features may also be provided: the diameter of the first water outlet hole 421 is the same as the diameter of the valve core water inlet hole 410 .

[0037] Some specific embodiments of the present invention may also have the following additional technical features: a corresponding escape space 211 is provided on the inner wall of the housing 210 corresponding to the nozzle outlet 430. The presence of the escape space 211 allows more water to remain between the housing 210 and the outer surface of the flow channel valve core 400, thereby generating a greater resistance pressure. When the spray gun switch 130 is turned on, the resistance pressure is greater than the pressure in the spray gun outlet 440 and the external air pressure, causing the water to be diverted to flow toward the spray gun body 110 and finally sprayed out from the spray gun body 110.

[0038] In some specific embodiments of the present invention, it may also have the following additional technical features: the valve core water inlet hole 410 is connected to the cold and hot water inlet pipes 500.

[0039] In some specific embodiments of the present invention, the following additional technical features may be provided: a mesh liner 221 is connected to the water outlet of the nozzle body 220. The mesh liner 221 is used to make the water outlet more uniform and reduce the impact force.

[0040] Working principle and working process:

[0041] When the switch valve 230 is closed, the blocking valve core 300 and the flow channel valve core 400 are tightly sealed and abutted. At this time, the valve core water outlet 420 and the valve core water inlet 410 are not connected, and no water flows out of the water nozzle or the spray gun body 110.

[0042] When the switch valve 230 is opened, the spray gun switch 130 is closed, the blocking valve core 300 is separated from the flow channel valve core 400, and the valve core water outlet hole 420 is connected to the valve core water inlet hole 410. Since the spray gun switch 130 is closed, the water cannot flow out of the spray gun body 110, and flows through the nozzle outlet channel 430 to the nozzle body 220, and finally flows out from the mesh 221;

[0043] When the switch valve 230 is opened and the spray gun switch 130 is turned on, the sealing valve core 300 is separated from the flow channel valve core 400. At this time, the valve core water outlet 420 is connected to the valve core water inlet 410. Since the spray gun switch 130 is turned on, the spray gun body 110 is connected to the outside world. The pressure in the spray gun water outlet 440 and the spray gun water outlet pipe 120 is lower than the pressure in the nozzle water outlet 430. The water flow begins to divert, and eventually the water level in the nozzle body 220 drops and no longer flows out, and the water flows out through the spray gun body 110.

[0044] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
