Description

Technical Field

[0001] This utility model relates to the field of bathroom fixtures, and in particular to a quick-start spray gun. Background Technology

[0002] The spray gun is connected to the water pipe and is used at a distance from the faucet. Therefore, the spray gun is equipped with a switch to independently control the water output. The current spray gun switches are opened and closed by rotating a lever or a button. The structure of the button is similar to the push-button switch of a ballpoint pen. It is submerged in the water circuit. Over time, the spring is prone to corrosion and is affected by the water pressure. The higher the water pressure, the more difficult it is to open and close. Utility Model Content

[0003] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the purpose of this invention is to provide a spray gun with an opening and closing structure that does not immerse itself in water.

[0004] To achieve the above objectives, embodiments of this utility model provide a quick-start spray gun, comprising: The frame has a first channel for water to flow in, and a second channel is formed at the end of the first channel. One end of the second channel has an outlet. The valve core is movably located inside the second channel. The valve core is connected to the button. The button and the frame form a temporary locking structure through a locking component located outside the frame. The locking assembly includes a slide rail located on at least one side of the frame and a lever that slides within the slide rail. The slide rail consists of a forward section and a backward section connected end to end, forming a first stable point and a second stable point at the junction of the two sections. One end of the lever slides within the slide rail and stops at different stable points in sequence, while the other end of the lever is hinged to a button.

[0005] According to an embodiment of the present invention, a quick-switch spray gun is designed such that pressing a button causes a pull rod to slide within a slide rail. When the pull rod stops at a stable point, the button stops, thereby causing the valve core to remain stationary, which in turn affects the flow of water in the second channel.

[0006] In addition, the quick-start spray gun proposed according to the above embodiments of this utility model may also have the following additional technical features: Optionally, the second channel has an annular protrusion inside, which makes the inner diameter of the second channel form a locally narrow section. The valve core locally forms a protrusion outward along the annular shape. When the valve core moves, the protrusion cooperates with the narrow section to close or open the second channel.

[0007] Optionally, it also includes a housing fitted over the frame, and the button is movable within the housing.

[0008] Optionally, the forward section is located at the upper part of the slide, the backward section is located at the lower part of the slide, and the first stable point and the second stable point are located on the same horizontal plane.

[0009] Furthermore, the advancing segment arches forward and upward from the first stable point, then bends sharply downward and backward after passing the second stable point to connect with the second stable point. The retreating segment extends forward and downward, forming a parallel segment before bending sharply backward and connecting with the first stable point in a straight line.

[0010] Optionally, one end of the pull rod is hinged to the button, which can swing up and down. The button is provided with a support member that abuts against the pull rod, so that the downward swing of the pull rod does not exceed the lowest point of the backward segment.

[0013] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0014] This utility model allows the button to be pressed, causing the pull rod to slide within the slide. When the pull rod stops at a stable point, the button comes to rest, thus keeping the valve core stationary and affecting the flow of water in the second channel.

[0015] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0016] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0017] Figures 1 to 6 A quick-start spray gun according to the present invention includes: The frame 1 has a first channel 11 inside which water flows in, and a second channel 12 at the end of the first channel 11. One end of the second channel 12 has an outlet 121. The valve core 2 is movably located inside the second channel 12 and is connected to the button 3. The button 3 forms a temporary locking structure with the frame 1 through a locking component located outside the frame 1. One end of the first channel 11 has an external thread and is screwed and sealed to the water inlet pipe to provide water inlet. The second channel 12 is open at both ends. One end is blocked by the valve core 2, which has a sealing ring so that it can maintain a sealing effect even if it moves. The outlet 121 at the other end has a cavity and multiple through holes to spray water out.

[0018] Specifically, the second channel 12 has an annular protrusion inside, which makes the inner diameter of the second channel 12 form a locally narrow section. The valve core 2 forms a protrusion along the annular direction. When the valve core 2 moves, the protrusion cooperates with the narrow section to close or open the second channel 12.

[0019] The locking assembly includes a slide rail 4 located on at least one side of the frame 1 and a lever 5 that slides within the slide rail 4. The slide rail 4 is composed of a forward section 41 and a backward section 42 connected end to end, and a first stable point 43 and a second stable point 44 are formed at the junction of the two sections. One end of the lever 5 slides within the slide rail 4 and stops at different stable points in sequence, while the other end of the lever 5 is hinged to the button 3.

[0020] Optionally, the forward section 41 is located at the upper part of the slide 4, and the backward section 42 is located at the lower part of the slide 4. The first stable point 43 and the second stable point 44 are located on the same horizontal plane. Further, the forward section 41 arches forward and upward from the first stable point 43, passes the second stable point 44, and then bends at an acute angle backward and downward to connect with the second stable point 44. The backward section 42 extends forward and downward, forms a parallel section, and then bends backward at an acute angle, connecting with the first stable point 43 in a straight line. The slide 4 of this design is shaped like a flattened heart. Therefore, when the button 3 is pressed, the lever 5 starts from the first stable point 43, is pushed forward, and then contacts the arched forward section 41, causing the lever 5 to lift up. Following the forward section 41, it falls down after reaching the vicinity of the second stable point 44. Due to the acute angle bend backward, the falling distance is limited and will not exceed the second stable point 44. At this time, the button retracts, causing the lever 5 to retract and engage with the second stable point 44.

[0021] Press the button again, and lever 5 is pushed out from the second stable point 44. Under the influence of gravity, lever 5 will continue to fall until it enters the lowest point of the backward segment 42. At this time, the push rod continues to move forward, and lever 5 will continue to slide forward in the parallel segment. The purpose of the parallel segment is to provide a cushioning effect. In order for lever 5 to fully enter the backward segment 42 after button 3 is pressed, the travel of button 3 will be greater than the swing distance of lever 5. Therefore, the parallel segment allows lever 5 to slide a certain distance, providing a cushioning feel to the button.

[0022] Within the slide rail 4, lever 5 starts from the first stable point 43. At this point, the button is retracted to its maximum position, and the valve is closed. Pressing the button causes lever 5 to move forward from the first stable point 43 along the forward section 41, lifting upward until it enters the second stable point 44. Then, valve core 2 opens the first channel 11, and water flows out from the outlet 121. Releasing button 3 causes the lever to spring back, thus stabilizing lever 5 at the second stable point 44. At this point, valve core 2 remains in the open state.

[0023] Press the button again, starting from the second stable point 44. Since the button still has a forward travel, the lever 5 is pushed forward until it fully enters the retraction section 42. When the button 3 is released and springs back, the lever 5 is brought back to the first stable point 43, and the valve core 2 is closed.

[0024] Specifically, the end of the pull rod 5 is bent inward into the slide rail 4, and the cross-section of the pull rod 5 is circular, so the inwardly bent part can slide in the slide rail 4.

[0025] Optionally, one end of the pull rod 5 is hinged to the button 3, which can swing up and down. The button 3 is provided with a support member, which abuts against the pull rod 5 so that the downward swing of the pull rod 5 does not exceed the lowest point of the backward segment 42.

[0026] Optionally, it also includes a housing 6, which is fitted onto the frame 1, and the button 3 moves within the housing 6.
