[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] This application provides a technical solution: A type of feminine wash nozzle, please refer to Figures 1-14 The device includes a grip tube 10, which has an upper cavity 100, a middle cavity 102 and a lower cavity 101 connected in sequence. Specifically, the upper side wall of the middle cavity 102 is provided with an outlet 103 that communicates with the upper cavity 100, and the lower side wall of the middle cavity 102 is provided with an inlet 104 that communicates with the lower cavity 101. The water first enters the lower chamber 101, then flows into the middle chamber 102 from the inlet 104, and then flows into the upper chamber 100 from the outlet 103.

[0030] The nozzle 12 is fixed to one end of the grip tube 10 and communicates with the upper cavity 100. The nozzle 12 has a nozzle 13 at its opening. The nozzle 13 has multiple microholes communicating with the inside of the nozzle 12. Water flows into the nozzle 12 from the upper cavity 100 and finally sprays out from the nozzle 13. The nozzle 12, grip tube 10 and nozzle 13 are all existing conventional technologies. In this application, the nozzle 12 and grip tube 10 can be welded and fixed. The nozzle 13 can be threaded to the nozzle 12. Of course, the threaded connection can be sealed with a sealing structure (e.g., rubber sealing ring) to prevent water leakage.

[0031] The bottom end of the grip 10 is fixed with a threaded connector 11, which facilitates connection with an external water pipe joint.

[0032] Press switch 2; Press switch 2 is located in the middle cavity 102 and is used to control the connection or disconnection of water flow; Specifically, press switch 2 is used to control the connection or disconnection of water inlet 104 and water outlet 103. When press switch 2 connects water inlet 104 and water outlet 103, water can flow smoothly from water inlet 104 into the middle cavity 102, and then from water outlet 103 into the upper cavity 100; When press switch 2 disconnects water inlet 104 and water outlet 103, water cannot flow from the middle cavity 102 to water outlet 103, and water cannot enter the upper cavity 100.

[0033] See Figures 4-10The push switch 2 in this application includes a tube body 20, a valve plate 26, an elastic component 27, and a push rod 25. One end of the central cavity 102 extends to the outside of the grip tube 10 to form an internal threaded ring 105. The tube body 20 is threadedly connected to the internal threaded ring 105. The interior of the central cavity 102 is a cylindrical cavity. One end of the tube body 20 is provided with a limiting protrusion ring 23. The outer wall of the tube body 20 near the limiting protrusion ring 23 is provided with an external thread that matches the internal threaded ring 105. During installation, the section of the tube body 20 without external threads can be inserted into the central cavity 102 first, and then the external threaded part of the tube body 20 can be threadedly connected to the internal threaded ring 105 until the limiting protrusion ring 23 is pressed against the end of the internal threaded ring 105. A sealing ring is bonded to the side of the limiting protrusion 23 near the internal threaded ring 105. When the limiting protrusion 23 is pressed against the end of the internal threaded ring 105, the sealing ring can achieve a sealing effect.

[0034] Of course, the inner wall of the middle cavity 102 is provided with a limiting ring 108 integrally formed with the gripping tube 10. The limiting ring 108 is located between the outlet 103 and the inlet 104. The outer wall of the tube body 20 is provided with a step 21 at the other end. A sealing ring is fitted on the step 21 and the sealing ring is adhered to the step 21. When the external thread of the tube body 20 is threadedly connected to the internal thread ring 105, and the limiting protrusion ring 23 is pressed against the end of the internal thread ring 105, the step 21 and the limiting ring 108 are also pressed tightly. The sealing ring on the step 21 will be pressed by the step 21 and the limiting ring 108 to achieve a sealing effect. In this application, one end of the pressing rod 25 extends to the outside of the internal threaded ring 105, and the other end of the pressing rod 25 is fixedly connected to the valve plate 26. The valve plate 26 is located at the other end of the pipe body 20. The two ends of the elastic member 27 are respectively connected to the inner wall of the middle cavity 102 and the valve plate 26. The water inlet 104 is located below the elastic member 27. The elastic member 27 can be a compression spring. The elastic member 27 can push the valve plate 26 to the other end of the pipe body 20. A sealing ring is sleeved on the side of the valve plate 26 near the pipe body 20. At the same time, the sealing ring is bonded and fixed to the valve plate 26. When the valve plate 26 is at the other end of the pipe body 20, the sealing ring on the valve plate 26 can play a sealing role and prevent the water flowing into the water inlet 104 from entering the pipe body 20. When the pressing rod 25 is pushed to separate the valve plate 26 from the pipe body 20, the water can flow into the pipe body 20 from the water inlet.

[0035] To facilitate the flow of water from the pipe body 20 into the upper cavity 100, multiple through grooves 200 are provided along the circumference of the outer wall of the pipe body 20. The through grooves 200 are connected to the inside of the pipe body 20 and are located below and connected to the outlet 103. Thus, when the push rod 25 is pushed to separate the valve plate 26 from the pipe body 20, water can flow into the pipe body 20 from the inlet 104. Then, the water flows through the through grooves 200 and the outlet 103 and finally into the upper cavity 100.

[0036] The outer wall of the tube body 20 is provided with an annular groove 201, and a first sealing ring 22 is fitted inside the annular groove 201. When the tube body 20 is placed in the middle cavity 102, the first sealing ring 22 can seal the connection between the outer wall of the tube body 20 and the inner wall of the middle cavity 102. Of course, multiple annular grooves 201 can be provided, and each annular groove 201 is provided with a first sealing ring 22 to enhance the sealing effect.

[0037] In this application, an annular groove 202 is provided inside the tube body 20, and a second sealing ring 24 is embedded in the annular groove 202. The second sealing ring 24 can play a sealing role and further enhance the sealing effect on the tube body 20. The pressing rod 25 passes through the second sealing ring 24, and the second sealing ring 24 abuts against the pressing rod 25. The pressing rod 25 can move relative to the second sealing ring 24.

[0038] It is worth noting that all the sealing rings in this application can be made of silicone.

[0039] The grip tube 10 is provided with a frame 106, which is integrally formed with the grip tube 10, and the internal threaded ring 105 is located inside the frame 106.

[0040] Pressing element 30 is located at the pressing end of the pressing switch 2. Specifically, pressing element 30 is slidably inserted into the frame 106 and connected to one end of the pressing rod 25.

[0041] The pressing member 30 has a first position and a second position. When the pressing member 30 is in the first position (the valve plate 26 abuts against the other end of the pipe body 20), the pressing switch 2 controls the water flow to be disconnected. When the pressing member 30 is in the second position (the pressing member 30 slides into the frame 106 and abuts against the frame 106, so that the pressing member 30 can no longer slide into the frame 106), the pressing switch 2 controls the water flow to be connected. At this time, the valve plate 26 is separated from the pipe body 20, and the water flow can flow into the pipe body 20 from the inlet 104. Then the water flow passes through the through groove 200 and the outlet 103, and finally flows into the upper cavity 100. An adjusting block 32 is slidably mounted on a pressing member 30. The pressing member 30 has a groove 300 on the side away from the grip tube 10, and the bottom of the groove 300 is connected to the outside. The adjusting block 32 is slidably connected in the groove 300. Specifically, sliders 33 are fixedly connected to both sides of the inner wall of the groove 300, and sliding grooves 320 are provided on both sides of the adjusting block 32. The two sliders 33 are slidably adapted to the two sliding grooves 320 respectively. Pushing the adjusting block 32 can achieve sliding.

[0042] It is worth noting that a rubber friction plate is fixedly connected to the inner wall of the slide groove 320. The rubber friction plate is in contact with the slider 33 to increase the friction. Under the action of the weight of the adjusting block 32 itself, it will not slide in the groove 300. Only when a pushing force is applied manually will the adjusting block 32 slide.

[0043] When the pressing member 30 is in the second position, moving the adjusting block 32 downwards will limit the pressing member 30 to the second position, and moving the adjusting block 32 upwards will release the limitation on the pressing member 30. Specifically, a first limiting groove 107 is provided at the bottom of the frame 106. When the pressing member 30 is in the second position, moving the adjusting block 32 downwards will insert the lower part of the adjusting block 32 into the first limiting groove 107. The bottom of the adjusting block 32 is provided with a U-shaped second limiting groove 321. The second limiting groove 321 forms two vertical plates at the bottom of the adjusting block 32. When the pressing member 30 is in the second position, the vertical plate at the rear of the bottom of the adjusting block 32 is exactly above the first limiting groove 107. The bottom of the adjusting block 32, with its front vertical plate positioned just outside the frame 106, allows the adjusting block 32 to slide downwards, enabling the rear vertical plate to insert into the first limiting groove 107, thus limiting the adjusting block 32 and consequently limiting the pressing member 30. At this time, the pressing member 30 drives the pressing rod 25 to push the valve plate 26 to remain separated from the pipe body 20, allowing the nozzle to spray water continuously. This way, when continuous water output from the nozzle is required, the operator does not need to hold the switch down for an extended period, reducing hand fatigue.

[0044] To facilitate the thumb pushing of the adjustment block 32, a finger groove 322 is provided on the adjustment block 32, which makes it easy for the operator to put the thumb into the finger groove 322. The finger groove 322 is recessed from the edge to the center, and the design of the finger groove 322 also makes it easy to push the adjustment block 32.

[0045] It is worth noting that a circular groove 301 is provided in the groove 300, and a through hole 302 is provided in the circular groove 301. A threaded groove 250 is provided at the center of one end of the pressing rod 25. It also includes a bolt. The bolt passes through the through hole 302 and is threadedly connected to the threaded groove 250, so that the pressing part 30 and the pressing rod 25 can be connected together.

[0046] The pressing member 30 has a receiving groove 303 on the side near the grip tube 10. Two positioning protrusions 31 are fixedly connected in the receiving groove 303 near the through hole 302. One end of the pressing rod 25 is located in a positioning groove 251 that corresponds to the position of the two positioning protrusions 31 and is of the same size. The positioning protrusions 31 can be inserted into the positioning groove 251. At this time, the through hole 302 corresponds exactly to the thread groove 250. After the positioning protrusions 31 are inserted into the positioning groove 251, the pressing rod 25 will not rotate when the bolt is tightened, which facilitates the tightening of the bolt. The design of the round groove 301 facilitates the receiving end of the bolt.

[0047] The feminine wash nozzle of this application, when in use: When short-term control of the nozzle water output is required, or when multiple short-term control of the nozzle water output and subsequent shut-off are needed: the user holds the handle 10 and presses the pressing element 30 with their thumb. The pressing element 30 will drive the pressing rod 25 to push the valve plate 26 away from the pipe body 20, causing the valve plate 26 to separate from the pipe body 20. At this time, the water will flow from the inlet 104 into the middle cavity 102, then into the pipe body 20, and from the through groove 200 to the outlet 103, entering the upper cavity 100, and finally spraying out from the nozzle. During this time, the elastic component 27 is continuously compressed. When the nozzle water output is not needed, the user slowly releases the pressing element 30 with their thumb. Under the elastic force of the elastic component 27, the valve plate 26 will be pushed back to its original position and abut against the pipe body 20 to achieve a seal, preventing water from entering the pipe body 20. The pressing element 30 will also be reset.

[0048] When short-term control of the nozzle's water output is required, the user holds the handle 10 and presses the press member 30 with their thumb. The press member 30 drives the press rod 25 to push the valve plate 26 away from the pipe body 20, causing the valve plate 26 to separate from the pipe body 20. At this time, water flows from the inlet 104 into the middle cavity 102, then into the pipe body 20, flows from the through groove 200 to the outlet 103, enters the upper cavity 100, and finally sprays out from the nozzle. During this time, the elastic component 27 is continuously compressed. When the press member 30 can no longer be pressed, the user flicks the adjusting block 32 downwards with their thumb, allowing the vertical plate on the rear side of the adjusting block 32 to insert into the first limiting groove 107, thus limiting the adjustment block 32. The pressing element 30 is limited, at which point the pressing element 30 drives the pressing rod 25 to push the valve plate 26 to continuously separate from the pipe body 20, allowing the nozzle to continuously spray water. When the pressing element 30 is released, it will not reset. In this way, when the nozzle needs to continuously spray water, the operator does not need to hold the switch for a long time, reducing hand fatigue. When the pressing element 30 needs to be reset, the thumb pushes the adjusting block 32 upward, which can disengage the vertical plate on the rear side of the adjusting block 32 from the first limiting groove 107. When the pressing element 30 is released, it can be reset under the action of the elastic component 27. At the same time, the valve plate 26 resets and abuts against the pipe body 20 to achieve a seal, preventing water from entering the pipe body 20.

[0049] It is worth noting that all of the above water control operations can be performed with one hand. This frees up the other hand when actually using the spray nozzle for rinsing, making it easier to use a brush or apply cleaning solution to the spray nozzle, thus improving its practicality.

[0050] It is worth noting that when the pressing component 30 is in the reset state, the rear side of the adjusting block 32 is located in front of the frame 106, so the adjusting block 32 can be removed directly, which facilitates loosening the bolts and disassembling the pressing component 30.
