Abstract
Description
Technical Field
[0001] This utility model relates to a liquid injection device, specifically to a nozzle. Background Technology
[0002] The water pipe connector of the high-pressure liquid nozzle can rotate relative to the nozzle to achieve different types of water flow being sprayed outward from the nozzle. For example, the patent document with authorization announcement number CN 201161216Y discloses a quick-switching combination nozzle, which mainly uses a rotating spray body to rotate relative to a fixed spray body, so that nozzles of different shapes located on the circumference of the rotating spray body are respectively connected to the channel outlet on the fixed spray body, thereby forming a multi-nozzle rotation switching structure. Utility Model Content
[0003] The technical problem solved by this utility model is to improve the existing nozzles to form different types of nozzles, so that the water flow they spray is not limited to different angles, thereby expanding the application range of the nozzles.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-pressure liquid nozzle, including a water pipe connector, a fixed part fixedly connected to the water pipe connector, and a movable part sleeved around the fixed part. The fixed part is provided with a water outlet channel communicating with the water pipe connector. The front end of the movable part is provided with several nozzles. Any nozzle can communicate with the water outlet channel due to the rotation of the movable part relative to the fixed part. The several nozzles include a type I nozzle and a type II nozzle. When the type I nozzle is connected to the water outlet channel, water from the water outlet channel is directly sprayed outward through the type I nozzle. The type II nozzle is connected to the water outlet channel through a guide cavity. Water from the water outlet channel enters the guide cavity and is then sprayed outward through the type II nozzle.
[0005] One type of nozzle comprises several nozzles of different shapes, with the water jets directed outward at different angles. The water jets from the second type of nozzle, guided by a guide cavity, exhibit a different shape than those from the first type. This expands the application range of the nozzle of this application.
[0006] The movable part includes a nozzle component with several nozzles, and a cylindrical movable part body. A first sealing ring and a second sealing ring separate the space between the nozzle component and the movable part body to form the guide cavity.
[0007] A flow guiding structure is installed inside the guiding cavity, through which water is ejected from the second type of nozzle. For example, the flow guiding structure has a spiral structure, through which water is ejected from the second type of nozzle, resulting in a spiral-shaped water flow.
[0008] The nozzle component has a convex structure, and the water flow channel of a type of nozzle is integrated on the convex structure. A first sealing ring is set on the convex structure to block the communication between the type of nozzle and the guide cavity. The main body of the movable part has a concave structure inside, and the convex structure fits into the concave structure.
[0009] The rotation center line of the movable part coincides with the center line of the water pipe connector. The water pipe connector is connected to the tail end of the fixed part. Thus, the water pipe connector is located at the center of the fixed part, and when the movable part rotates on the fixed part, the water pipe connector is also located at the center of the movable part. Unlike existing technologies where the water pipe connector is off-center from the nozzle, this design makes the entire nozzle shape regular and aesthetically pleasing, and also provides the user with a good operating feel.
[0010] Each nozzle is connected to the water outlet channel, which in turn is connected to the water pipe connector. Water from the water pipe passes through the water pipe connector and the water outlet channel before being ejected from the nozzle. Several nozzles have different shapes, and the user can rotate the movable part relative to the fixed part. Different nozzles are connected to the water outlet channel, resulting in different water jet shapes to suit different usage scenarios.
[0011] The fixed part has a connector at its tail, and the movable part connects to the connector, axially pressing the parts in the movable part together. The entire high-pressure liquid nozzle has no external connecting parts such as screws, bolts, or pins, making it appear simple and aesthetically pleasing. Furthermore, the axial pressing of the movable part with the connector results in a slender shape for the entire high-pressure liquid nozzle, improving the grip during use.
[0012] The connector includes a disc-shaped fixing part and a cylindrical movable part sleeved on the water pipe joint. The disc-shaped fixing part is fixedly engaged with the water pipe joint, and the cylindrical movable part is pivotally connected to the disc-shaped fixing part. The movable part is screwed onto the cylindrical movable part.
[0013] Alternatively, a radial limiting device is provided between the outer perimeter of the fixed part and the inner wall of the movable part, which can limit the position where any nozzle connects with the water outlet channel.
[0014] Regarding the radial limiting device: The fixed part is divided into a rotating section and a positioning section. The periphery of the positioning section is provided with several slots. The inner wall of the movable part is provided with a spring piece. The spring piece has a protrusion. The protrusion can engage with any slot due to the rotation of the movable part relative to the fixed part.
[0015] Regarding the radial limiting device: When the user rotates the movable part, the spring bends towards the inner wall of the movable part, and the protrusion disengages from the engaged slot, sliding along the outer wall of the positioning section. After the movable part rotates a certain angle relative to the fixed part, the protrusion aligns with the next slot, the bent spring returns to its original position, and the protrusion engages with that slot, achieving temporary positioning of the movable part relative to the fixed part. At this time, one of the nozzles is connected to the water outlet channel. To connect other nozzles to the water outlet channel, the user continues to rotate the movable part, causing the protrusion on the spring to engage with other slots. When the protrusion on the spring engages with any slot, the water outlet channel connects to the corresponding nozzle.
[0016] Regarding the radial limiting device: In this invention, the rotating section and the positioning section are arranged back and forth along the axial direction of the fixed part. The front end of the rotating section mates with the front end of the movable part, which has several nozzles. This requires a sufficiently large area, and therefore a sufficiently large outer diameter. However, unlike existing technologies, this invention uses a spring clip for positioning the movable part relative to the fixed part. This spring clip engages with a latch on the positioning section. Since the outer diameter of the positioning section is smaller than that of the rotating section, the spring clip in this invention does not require the fixed part to have an enlarged outer diameter. The outer diameter of the fixed part only needs to accommodate the placement of all nozzles. Thus, compared to existing technologies, the outer diameter of the movable part surrounding the fixed part is correspondingly reduced, which is beneficial for the miniaturization and weight reduction of the high-pressure liquid nozzle. Moreover, since the fixed part is divided into a rotating section and a positioning section, the movable part surrounding the fixed part is elongated, making it easier for the user to grip and improving the operating feel.
[0017] Alternatively, an axial limiting device is provided between the fixed part and the moving part, which can limit the position where any nozzle connects with the water outlet channel.
[0018] Regarding the axial limiting device: The axial limiting device includes an axial spring and a steel ball disposed between the fixed part and the movable part. The axial spring and the steel ball abut against each other, and the steel ball engages with the positioning recess of the movable part.
[0019] Regarding the axial limiting device: When the user rotates the movable part, the steel ball moves away from the positioning recess on the end face of the nozzle and along the end face of the nozzle. After the movable part rotates a certain angle relative to the fixed part, the steel ball aligns with the next positioning recess. Under the action of the axial spring, the steel ball engages with the positioning recess, achieving temporary positioning of the movable part relative to the fixed part. At this time, one of the nozzles is connected to the water outlet channel. To connect other nozzles to the water outlet channel, the user continues to rotate the movable part, causing the steel ball to engage with other positioning recesses. When the steel ball engages with any positioning recess, the water outlet channel connects to the corresponding nozzle.
[0020] This application has the following technical effects:
[0021] First, among several nozzles, one type of nozzle focuses on solving the angle problem of the jet water flow, while the second type of nozzle solves the shape problem of the jet water flow.
[0022] Secondly, the user can rotate the movable part, and different nozzles are connected to the water outlet channel. The angle and shape of the water jets from the nozzles are different to adapt to different usage scenarios.
[0023] Third, the entire high-pressure liquid nozzle has no connecting parts such as screws, bolts, or pins on the outside, making it look simple and beautiful; moreover, the moving part and the connecting part axially press the parts in the moving part, making the entire high-pressure liquid nozzle slender and improving the grip during use.
[0024] Fourth, the spring of the radial limiting device does not require the outer diameter of the fixed part to be enlarged. The outer diameter of the fixed part only needs to meet the setting of all nozzles, which is conducive to the miniaturization and weight reduction of the high-pressure liquid nozzle. Moreover, since the fixed part is divided into a rotating section and a positioning section, the movable part sleeved on the periphery of the fixed part is slender, which is convenient for users to hold and improves the feel of operation.

[0051] First Embodiment
[0052] Combination Figure 1 , Figure 4 , Figure 5 , Figure 14 A high-pressure liquid nozzle includes a water pipe connector 10, a fixed part 20 fixedly connected to the water pipe connector, and a movable part 30 sleeved around the fixed part. The fixed part has a water outlet channel 201 communicating with the water pipe connector. The front end of the movable part has a plurality of nozzles 301. Any nozzle can communicate with the water outlet channel due to the rotation of the movable part relative to the fixed part. The fixed part is divided into a rotating section 21 and a positioning section 22. The periphery of the positioning section has a plurality of latches 23. The inner wall of the movable part is provided with a spring piece 31. The spring piece has a protrusion 310. The protrusion can cooperate with any latch due to the rotation of the movable part relative to the fixed part.
[0053] In actual use, the user moves the movable part 30, enabling any nozzle 301 to connect with the water outlet channel 201. The water outlet channel connects with the water pipe connector 10, and water from the water pipe passes through the water pipe connector 10 and the water outlet channel 201 before being sprayed out from the nozzle 301. Since the nozzles 301 have different shapes, the user can rotate the movable part 30 relative to the fixed part 20. Different nozzles 301 connect with the water outlet channel 201, resulting in different water jet shapes to suit different usage scenarios.
[0054] When the protrusion 310 on the spring piece 31 engages with any of the latches 23, the water outlet channel 201 connects with the corresponding nozzle. Initially, the protrusion 310 of the spring piece engages with one latch. The user rotates the movable part 30, causing the spring piece 31 to bend towards the inner wall of the movable part, accumulating elastic potential energy. The protrusion 310 then leaves the latched latch and slides along the outer wall of the positioning section 22. After the movable part 30 rotates a certain angle relative to the fixed part 20, the protrusion 310 aligns with the next latch, the bent spring piece returns to its original position, the elastic potential energy is released, and the protrusion 310 engages with the latch, achieving temporary positioning of the movable part 30 relative to the fixed part 20. At this time, the corresponding nozzle among the several nozzles connects with the water outlet channel 201. To connect other nozzles 301 with the water outlet channel 201, the user continues to rotate the movable part 30, causing the protrusion 310 on the spring piece 31 to engage with other latches 23.
[0055] Combination Figure 4 , Figure 5 The inner wall of the movable part 30 is provided with a pair of spring slots 32, and the two ends of the spring 31 are fitted in the pair of spring slots. The protrusion 310 is located in the middle of the spring and protrudes towards the center of the movable part.
[0056] Combination Figure 13 , Figure 14 The axis of the rotating section 21 coincides with the axis of the positioning section 22. The water outlet channel 201 is a curved waterway. The inlet end of the water outlet channel is located inside the positioning section 22, and the outlet end is located inside the outlet cavity 210 of the rotating section. The outlet end of the water outlet channel is offset from the center of the rotating section. The water pipe connector 10 is connected to the tail end of the positioning section 22. Thus, the water pipe connector 10 is located at the center of the fixed part 20, and the movable part 30 rotates on the fixed part, with the water pipe connector also located at the center of the movable part 30. This design differs from the prior art where the water pipe connector is offset from the center of the nozzle, resulting in a more regular and aesthetically pleasing overall nozzle shape.
[0057] The water outlet chamber 210 includes a small circular outlet chamber 211 connected to the water outlet end of the water outlet channel 201, a semi-circular chamber 212 connected to the small circular outlet chamber, and a large circular chamber 213 connected to the semi-circular chamber. The small circular outlet chamber 211 and the semi-circular chamber 212 are filled with water guide components 24, each with a water guide hole 240 that connects to the water outlet end of the water outlet channel 201. The movable part 30 includes a nozzle component 36 at its front end. The nozzle component is disc-shaped and fixedly fitted to the main body of the movable part. The nozzle component 36 has several nozzles 301. The tail of the nozzle component 36 fits into the large circular chamber 213. The nozzle component rotates with the main body of the movable part, and different nozzles 301 can connect with the water guide holes 240 on the water guide component, enabling different nozzles to communicate with the water outlet channel 201.
[0058] Combination Figure 2, Figure 3 , Figures 6 to 10 The water pipe connector 10 is fitted with a disc-shaped fixing member 33 and a cylindrical movable member 34. The disc-shaped fixing member is fixedly engaged with the water pipe connector 10, and the cylindrical movable member is pivotally connected to the disc-shaped fixing member. A U-shaped clamp 11 is engaged on the water pipe connector to restrict the axial displacement of the cylindrical movable member. The movable part 30 is screwed onto the cylindrical movable member, realizing the fixed connection between the movable part 30 and the cylindrical movable member 34. Since the U-shaped clamp 11 restricts the axial displacement freedom of the cylindrical movable member 34, the cylindrical movable member can rotate in place relative to the water pipe connector 10. The cylindrical movable member 34 drives the movable part 30 to rotate synchronously, realizing the rotation of the movable part 30 relative to the fixed part 20 and the water pipe connector 10. The disc-shaped fixing member 33 is provided with a limiting edge to circumferentially limit the rotation of the cylindrical movable member 34, so that the rotation center axis of the cylindrical movable member 34 coincides with the center axis of the cylindrical movable member 34 as much as possible.
[0059] Because the tail of the movable part 30 is screwed to the cylindrical movable member 34, the movable part tends to shift rearward relative to the cylindrical movable member 34. This tendency causes the nozzle member 36 located within the movable part 30 to press against the fixed part 20, which in turn presses against the water pipe connector 10. Subsequently, the U-shaped clip 11 engages with the water pipe connector 10, restricting the axial degree of freedom of the cylindrical movable member 34. Thus, the axial relative positions of the nozzle member 36, the fixed part 20, and the water pipe connector 10 are locked, but the rotational degree of freedom of the movable part 30 relative to the fixed part 20 is not affected.
[0060] The water pipe connector 10 is provided with a retaining ring 12 and circumferentially distributed stop blocks 13. The inner wall of the disc-shaped fixing member 33 is provided with a circumferential limiting groove 330 that mates with the stop blocks. The rear end face of the disc-shaped fixing member is limited by the retaining ring, and the front end face of the disc-shaped fixing member is limited by the U-shaped clamp 11. The stop blocks 13 mate with the circumferential limiting groove 330, thus restricting the rotational freedom of the disc-shaped fixing member 33 relative to the water pipe connector 10. The U-shaped clamp 11 and the retaining ring 12 limit the front and rear end faces of the disc-shaped fixing member 33, thus restricting the axial displacement freedom of the disc-shaped fixing member 33. In this way, the disc-shaped fixing member 33 is fixed to the water pipe connector 10.
[0061] The U-shaped clamp 11 restricts the axial displacement freedom of the disc-shaped fixing member 33 and also restricts the axial displacement freedom of the cylindrical movable member 34. The cylindrical movable member 34 has an inner hole and a U-shaped clamp slot 341. The inner diameter of the U-shaped clamp slot is larger than the inner diameter of the inner hole 342 of the cylindrical movable member. The U-shaped clamp slot and the inner hole of the cylindrical movable member are arranged front and rear. The front end of the disc-shaped fixing member 33 has an extension piece 332, which fits in the inner hole 342 of the cylindrical movable member. The U-shaped clamp 11 fits in the U-shaped clamp slot and also fits in the U-shaped clamp groove 101 of the water pipe connector. Because the inner diameter of the U-shaped locking slot is larger than the inner diameter of the cylindrical movable part's inner hole 342, the forward axial displacement freedom of the cylindrical movable part 34 is restricted, and the backward axial displacement freedom of the cylindrical movable part 34 is restricted by the disc-shaped fixing part 33. Thus, the axial displacement freedom of the cylindrical movable part 34 is restricted, but the rotational freedom of the cylindrical movable part 34 relative to the water pipe connector 10 is not affected. The U-shaped locking part 11 effectively restricts the axial displacement freedom of both the disc-shaped fixing part 33 and the cylindrical movable part 34.
[0062] like Figure 6 As an improvement, a stop 343 is provided at the tail of the cylindrical movable part 34, and a ratchet 35 that can engage with the stop is provided on the inner wall of the tail of the movable part 30. After the movable part 30 and the cylindrical movable part 34 are screwed to the bottom, the ratchet 35 contacts and engages with the stop 343. The stop prevents the movable part 30 from rotating in one direction relative to the cylindrical movable part 34 and restricts its reverse rotation. In this way, when the movable part 30 rotates relative to the fixed part 20 to adjust the position of the nozzle 301, the movable part 30 and the cylindrical movable part 34 will not become loose due to the reverse rotation of the movable part 30 relative to the fixed part 20.
[0063] Combination Figure 13 , Figure 14 The fixed part 20 has a rearwardly extending strip 25 at its tail end, and the water pipe connector 10 has an axially extending strip groove 102 at its front end. The strip fits into the strip groove and extends rearward into the inner hole 331 of the disc-shaped fixing member. The disc-shaped fixing member 33, which is sleeved on the water pipe connector 10, can press the strip 25 together, stabilizing the connection between the fixed part 20 and the water pipe connector 10, and making them coaxial. Moreover, the cooperation between the strip 25 and the strip groove 102 restricts the rotational freedom of the fixed part 20 relative to the water pipe connector 10, improving the stability of the fixed connection between the two.
[0064] Second Embodiment
[0065] like Figures 15 to 17A high-pressure liquid nozzle includes a water pipe connector 10, a fixed part 20 fixedly connected to the water pipe connector, and a movable part 30 sleeved around the fixed part. The fixed part is provided with a water outlet channel 201 communicating with the water pipe connector. The front end of the movable part is provided with a plurality of nozzles. Any nozzle can communicate with the water outlet channel due to the rotation of the movable part relative to the fixed part. The plurality of nozzles include a first type of nozzle 301 and a second type of nozzle 302.
[0066] When a Class I nozzle is connected to the water outlet channel, water from the water outlet channel is sprayed directly outward through the Class I nozzle. When a Class II nozzle is connected to the water outlet channel through a guide cavity 362, water from the water outlet channel enters the guide cavity and is then sprayed outward through the Class II nozzle.
[0067] Combination Figure 16 , Figure 17 The movable part 30 includes a nozzle element 36 with a plurality of nozzles, and a cylindrical movable part body 300. A first sealing ring 371 and a second sealing ring 372 separate the space between the nozzle element and the movable part body to form the guide cavity 362.
[0068] like Figure 16 , Figure 17 , Figure 19 A flow guiding structure 363 is provided inside the guide cavity 362, through which water is ejected from the second type of nozzle 302. Specifically, water from the water outlet channel enters the guide cavity 362 through the inlet 366 of the guide cavity, and after passing through the flow guiding structure 363, the water is ejected from the second type of nozzle 302.
[0069] like Figure 17 , Figure 19 The nozzle component 36 has a convex structure 364, and the water flow channel of the nozzle 301 is integrated on the convex structure. A first sealing ring 371 is provided on the convex structure to block the communication between the nozzle and the guide cavity 362. The interior of the movable part main body 300 has a concave structure 39, and the convex structure fits into the concave structure.
[0070] like Figure 16 An axial limiting device is provided between the fixed part 20 and the movable part 30. The axial limiting device can limit the position where any nozzle connects with the water outlet channel.
[0071] like Figure 18 The axial limiting device includes an axial spring 381 and a steel ball 38 disposed between the fixed part 20 and the movable part 30. The axial spring abuts against the steel ball, and the steel ball cooperates with the positioning recess 365 of the movable part.
[0072] The user rotates the movable part 30, causing the steel ball 38 to move away from the positioning recess 365 on the end face of the nozzle component 36 and along the end face of the nozzle component. After the movable part 30 rotates a certain angle relative to the fixed part 20, the steel ball 38 aligns with the next positioning recess 365. Under the action of the axial spring 381, the steel ball 38 engages in the positioning recess, achieving temporary positioning of the movable part relative to the fixed part. At this time, one of the nozzles is connected to the water outlet channel. To connect other nozzles to the water outlet channel, the user continues to rotate the movable part 30, causing the steel ball 38 to engage with other positioning recesses. When the steel ball engages with any positioning recess 365, the water outlet channel connects to the corresponding nozzle.
[0073] Type 1 nozzles 301 include several nozzles of different shapes, with the water jets directed outward at different angles. Type 2 nozzles 302, due to the guidance of the guide cavity 362, exhibit a different shape from the water jets from Type 1 nozzles. For example, the guide structure 363 has a spiral structure, such as... Figure 19 Water is then ejected from the spiral structure through the second type of nozzle 302, resulting in a spiral-shaped water flow.
[0074] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
