[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] Refer to Figures 1 to 15 As shown, in a preferred embodiment of the present invention, a flow - regulating spray gun includes a main body assembly 1, a switching assembly 2 and a flow - regulating assembly 3 provided in the main body assembly 1. Water flow enters from the water inlet end of the main body assembly 1, passes through the opened flow - regulating assembly 3, and flows out through the water outlet channel selected and determined by the switching assembly 2 for use.

[0041] The main body assembly 1 has a water inlet channel and at least two water outlet channels. The switching assembly 2 is provided between the water inlet channel and the water outlet channels so that the switching assembly 2 selects one of the water outlet channels to communicate with the water inlet channel.

[0042] The main body assembly 1 includes a housing 11, a body 13 provided in the housing 11, a base 14 provided below the body 13, and a water - passing channel 12 communicated with the body 13. The water - passing channel 12 is provided at one end away from the base 14. In this embodiment, there are two water outlet channels. The water outlet channels are provided on the body 13 and penetrate the base 14. Both the switching assembly 2 and the flow - regulating assembly 3 are inserted on the body 13. The water inlet channel is provided on the water - passing channel 12. Water flow enters from the water - passing channel 12, flows to the body 13 and flows out from the base 14.

[0043] The housing 11 has a cavity, an inlet hole, an outlet hole and a switching hole communicating with the cavity. The switching hole is arranged above the outlet hole, and the inlet hole and the outlet hole are arranged away from each other. The water inlet end of the water passage 12 penetrates through the inlet hole. The body 13 is arranged at one end of the cavity far from the inlet hole. The switching assembly 2 is inserted into the body 13 and penetrates through the switching hole. An outlet body 15 corresponding to the base 14 is covered on the outlet hole.

[0044] The body 13 has a valve cavity opened in the middle and two switching cavities arranged on both sides of the valve cavity. The flow control valve core 34 of the flow control assembly 3 is arranged in the valve cavity. The base 14 has a flow through hole corresponding to the switching cavity. The switching assembly 2 has two sets of switching structures, and the two switching structures are distributed in the two switching cavities so that the water flow can be selected to flow into one of the flow through holes. The flow control valve core 34 is arranged between the switching assemblies 2, which can reduce the volume of the spray gun. It can ensure that the volume of the spray gun does not increase under the condition of increasing the water outlet function and adjustable flow, and has stronger practicability compared with the single-function spray guns on the market at present. In this embodiment, the water outlet water path corresponding to the flow through hole close to the water passage 12 is the particle water outlet water path, and the water outlet water path corresponding to the flow through hole far from the water passage 12 is the spray gun water outlet water path.

[0045] In other embodiments, the number of the switching cavities can be three, four, five, etc. The switching cavities can be arranged around the valve cavity. The body 13 is correspondingly provided with the same number of water outlet water paths. The flow through holes on the base 14 still correspond to the switching cavities. The switching assembly 2 has corresponding switching structures, so that the spray gun can have more groups of water outlets and the switching can be completed through the switching assembly 2. This functional requirement can be selected and configured according to the needs of customers. No matter how many water outlet switches there are, they are all within the protection scope of the present invention.

[0046] The outlet body 15 is provided with an outlet corresponding to the flow through hole. The water flow flows through the switching selection of the switching assembly 2 to the corresponding flow through hole on the base 14 and flows out for use from the outlet.

[0047] The switching component 2 is a seesaw multi-axis control structure, and the seesaw multi-axis control structure includes a switching member 21 and at least two switching structures connected below the switching member 21. In this embodiment, the switching component 2 is a seesaw two-axis control structure, which includes the switching member 21 and two switching structures connected below the switching member 21. Each switching structure has a switching rod 22 and a seal sleeved on the switching rod 22. The switching structure is inserted into the switching cavity, and the seal is arranged at one end close to the flow-through hole, and the seal blocks or moves away from the flow-through hole to prevent or allow water flow to pass through.

[0048] A clamping joint is arranged at one end of the switching rod 22 close to the switching member 21, and a clamping position corresponding to the switching cavity is arranged on one side of the switching member 21 close to the switching rod 22. The clamping joint is clamped in the clamping position to make the switching rod 22 and the switching member 21 clamped to each other. In this embodiment, there are two switching rods 22, and the clamping positions correspond to the switching rods 22 and are arranged away from each other, thus forming the seesaw two-axis control structure. Press the position of the switching member 21 corresponding to any one of the switching rods 22, and the corresponding seal blocks the corresponding flow-through hole and makes the other flow-through hole unblocked.

[0049] The flow regulating component 3 also has a connecting structure connected above the flow regulating valve core 34 and a regulating knob 32 connected to one end of the connecting structure away from the flow regulating valve core 34. A through groove is formed on the upper wall surface of the housing 11, and the through groove is arranged between the inlet and the switching port. The regulating knob 32 is movably penetrated through the through groove; the connecting structure has an adjusting wheel 33 sleeved on the flow regulating valve core 34 and a connecting rod 31 movably connected to the adjusting wheel 33. By operating the regulating knob 32 to drive the connecting rod 31 to drive the adjusting wheel 33 to rotate, the flow regulating valve core 34 is driven to rotate to adjust the flow rate.

[0050] The flow regulating valve core 34 has a movable valve plate and a static valve plate which are rotatably and correspondingly arranged. The static valve plate has water passing holes 341 corresponding to the flow-through holes, and the multiple water passing holes 341 are arranged away from each other; the movable valve plate has at least one water passing hole 342, and water flow can pass through only when the water passing hole 342 is communicated with any one of the water passing holes 341. In this embodiment, there are two water passing holes 342, and the two water passing holes 342 are arranged away from each other. The distances between the two water passing holes 342 and the two water passing holes 341 are the same. By relatively rotating the movable valve plate and the static valve plate, it can be ensured that the water passing holes 341 and the water passing holes 342 coincide or are away from each other. Both the movable valve plate and the static valve plate are made of ceramic sheets, which have good sealing performance, strong reliability, and can ensure the stability of flow rate adjustment and water switching, as well as ensure the service life.

[0051] The inner wall surface of the adjusting wheel 33 is provided with internal spline teeth, and the flow regulating valve core 34 is provided with external spline teeth on the side close to the adjusting wheel 33. The internal spline teeth are inserted into the external spline teeth so that when the adjusting wheel 33 rotates, it can drive the flow regulating valve core 34 to rotate, causing the moving valve plate and the static valve plate to rotate relative to each other. The outer wall surface of the adjusting wheel 33 is annularly provided with first engaging teeth, and the second engaging teeth are provided in the length direction of one end of the connecting rod 31 close to the adjusting wheel 33. The first engaging teeth and the second engaging teeth are engaged with each other so that the connecting rod 31 can drive the adjusting wheel 33 to rotate. When the adjustment knob 32 is manipulated, the connecting rod 31 moves with the adjustment knob 32 and drives the adjusting wheel 33 to rotate, thereby controlling the rotation of the flow regulating valve core 34, and further performing flow rate adjustment and water on / off control.

[0052] The working principle of the present invention is briefly described as follows:

[0053] Reference Figure 5 and Figure 6 As shown in the figure, when the adjustment knob 32 moves forward, the connecting rod 31 drives the adjusting wheel 33 to rotate counterclockwise. The adjusting wheel 33 drives the flow regulating valve core 34 to open, and the overlapping area of the water passing hole 341 and the water passing through hole 342 gradually becomes larger, thereby increasing the water inlet area. At the same time, one end of the switching member 21 close to the water passing channel 12 is pressed down, and the switching rod 22 at one end of the switching member 21 close to the water passing channel 12 moves downward to block the corresponding flow hole, thereby blocking the water outlet path of the granular water. The switching rod 22 at the end far from the water passing channel 12 moves upward to open the corresponding flow hole, thereby enabling the water outlet path of the spray gun water to discharge water.

[0054] Reference Figure 7 and Figure 8 As shown in the figure, when the adjustment knob 32 moves backward, the connecting rod 31 drives the adjusting wheel 33 to rotate clockwise. The adjusting wheel 33 drives the flow regulating valve core 34 to close, and the overlapping area of the water passing hole 341 and the water passing through hole 342 gradually becomes smaller, thereby closing the water inlet area. At the same time, even if one end of the switching member 21 close to the water passing channel 12 is in the pressed-down state, and the switching rod 22 at the end far from the water passing channel 12 moves upward to open the corresponding flow hole, the water path of the spray gun water still cannot be unblocked to discharge water.

[0055] Reference Figure 9 and Figure 10As shown, the tuning knob 32 moves forward, the connecting rod 31 drives the adjusting wheel 33 to rotate counterclockwise, the adjusting wheel 33 drives the flow control valve core 34 to open, and the overlapping area of the water passing hole 341 and the water passing hole 342 gradually increases, thereby increasing the water inlet area. At the same time, the end of the switching member 21 away from the water passing channel 12 is pressed down, the switching member 21 drives the switching rod 22 at the end away from the water passing channel 12 to move downward to block the corresponding flow hole, thereby blocking the water outlet path of the spray gun water, and the switching rod 22 at the end close to the water passing channel 12 moves upward to open the corresponding flow hole, thereby allowing the water outlet path of the granular water to discharge water.

[0056] Reference Figure 11 and Figure 12 As shown, the tuning knob 32 moves backward, the connecting rod 31 drives the adjusting wheel 33 to rotate clockwise, the adjusting wheel 33 drives the flow control valve core 34 to close, and the overlapping area of the water passing hole 341 and the water passing hole 342 gradually decreases, thereby closing the water inlet area. At the same time, even if the end of the switching member 21 away from the water passing channel 12 is in a pressed-down state, the switching rod 22 at the end close to the water passing channel 12 moves upward to open the corresponding flow hole, but the water path of the granular water still cannot be unblocked to discharge water.

[0057] Reference Figure 13 As shown, when the overlapping area of the water passing hole 341 and the water passing hole 342 is in a completely overlapping state, the area through which water can flow is the largest. Reference Figure 14 As shown, when the water passing hole 341 and the water passing hole 342 are in a partially overlapping state, the water flow area decreases and is in a low-flow state. Reference Figure 15 As shown, when the water passing hole 341 and the water passing hole 342 are in a completely non-overlapping state, water cannot pass through and is in a closed state.

[0058] In the present invention, by providing a switching assembly 2 and a flow control assembly 3 in the main body assembly 1, and embedding the flow control valve core 34 of the flow control assembly 3 into the switching assembly 2 to reduce the volume of the spray gun, it is possible to ensure that the volume of the spray gun does not increase while increasing the water outlet function and adjustable flow, making it small and delicate, ensuring that the spray gun does not occupy bathroom space and meeting the user's usage requirements; by connecting the tuning knob 32 through a connection structure and then connecting it to the flow control valve core, the tuning knob 32 has both the functions of turning the water on and off and adjusting the flow rate, and the operation is simple and convenient; and by using ceramic sheets for the moving valve plate and the static valve plate of the flow control valve core 34, the sealing performance is good, the reliability is strong, and the stability of flow rate adjustment and water on / off can be ensured, guaranteeing the switching life; by setting the switching assembly 2 as a seesaw dual-axis control structure, the influence of water pressure on the switching force can be reduced, ensuring that the switching feel is light and making the user feel comfortable when using.
