Description

Technical Field

[0001] The present invention relates to the field of sanitary ware, in particular to a shower head and a urinal with adjustable water outlet amplitude. Background Art

[0002] Current urinal nozzle technology faces significant challenges in universality and integration. Traditional nozzles require customization of specific water outlet angles based on the shape and size of different urinals, resulting in the need to develop specialized nozzles for each new product, which compromises component universality. While existing adjustable-angle nozzles achieve angle adjustment through gear transmission, the two adjustment arms utilize a gear meshing structure. To ensure water flow from the outlet, this meshing structure must clear the outlet, occupying too much space to accommodate other functional components. Furthermore, due to the limited size of the urinal nozzle, the rotation axes of the two adjustment arms of this meshing structure are relatively far from the nozzle's axis, limiting the range of rotation of the adjustment arms and making it difficult to meet the needs of urinals requiring large-angle flushing. Summary of the Invention

[0003] The main purpose of the present invention is to overcome the defects in the prior art in which the adjustment arms of the nozzles adopt a gear meshing structure, the rotation axes of the two adjustment arms are far away from the nozzle axis, and the rotation range is limited. A nozzle and urinal with adjustable water outlet amplitude are proposed, which will reduce the distance between the rotation axis of the adjustment structure and the nozzle axis, reduce the radial occupied space, and increase the adjustable angle.

[0004] The present invention adopts the following technical solutions:

[0005] A sprinkler with adjustable water outlet amplitude comprises a main body, which is provided with a water inlet channel and a water outlet chamber connected to the water inlet channel, and also comprises an adjusting component and a transmission component. The adjusting component comprises two adjusting parts which are arranged in the water outlet chamber in a manner rotatable around the water inlet channel, the two adjusting parts forming a water outlet between the two ends away from the water inlet channel, and a water spraying channel connecting the water inlet channel and the water outlet is also formed between the two adjusting parts; the transmission component is respectively connected to the two adjusting parts, and is constructed to move as one of the two adjusting parts rotates and push the other of the two adjusting parts to rotate in the opposite direction, so that the two adjusting parts move toward or away from each other to adjust the water outlet amplitude.

[0006] The rotation axes of the two adjusting members are coaxially arranged, parallel to the central axis of the water inlet channel, and the projection points of the rotation axes on the radial section of the water inlet channel are located within the contour range of the water inlet channel.

[0007] The movement trajectory of the regulating member away from the end of the water inlet channel is an arc, and the projection point of the center of the arc on the radial section of the water inlet channel is located within the contour range of the water inlet channel.

[0008] The radial cross section of the body is a circle, and the projection point of the rotation axis of the adjusting member on the radial cross section of the water inlet channel coincides with the center of the circle.

[0009] The main body is also provided with a transmission cavity, which is located on the side of the water outlet cavity facing away from the water inlet channel; a transmission connector extending to the transmission cavity is provided at the end of the adjusting member where the water outlet is located; the transmission component is arranged in the transmission cavity and is transmission-connected to the two transmission connectors; by rotating the transmission connector of any adjusting member, the transmission assembly links the transmission connector of the other adjusting member to rotate in the opposite direction.

[0010] The adjusting parts are arranged along the radial direction of the water outlet cavity and the first ends thereof are respectively provided with shaft sleeves extending along the axial direction of the water outlet cavity. The two shaft sleeves of the two adjusting parts are coaxially nested and rotatably arranged in the water inlet channel. The second ends of the adjusting parts are provided with transmission connecting parts.

[0011] The transmission connecting part includes a bending section and an extension section. The bending section is connected to the end of the water outlet of the adjusting part and is bent along the axial direction of the water outlet cavity toward the transmission cavity. The extension section is connected to the bending section and extends radially along the water outlet cavity into the transmission cavity to connect with the transmission component.

[0012] A protrusion is provided on the side of the bending section away from the water outlet chamber to facilitate the control of the rotation of the transmission connecting part; the extending section is also provided with a first connecting part to be connected to the transmission part.

[0013] The transmission component includes two transmission members, which are arranged along the radial direction of the transmission cavity. The first ends of the two transmission members are provided with gears that mesh with each other, and the gear shafts are parallel to the axial direction of the transmission cavity. The second ends of the two transmission members are provided with second connecting parts to respectively connect to corresponding transmission connecting members; rotating any transmission connecting member causes the other transmission connecting member to rotate in the opposite direction through the gear meshing transmission, thereby realizing the toward or away movement of the two adjusting members.

[0014] An axially protruding first limiting portion is also provided in the transmission cavity. The first limiting portion is located between the two transmission members. When the two transmission members move toward each other and abut against the first limiting portion, the water discharge amplitude is minimized.

[0015] The main body is provided with a main body, a guide plate and a cover body; the main body is provided with an axially extending water inlet channel, and the axial end of the main body is provided with a radially extending guide part; the guide plate and the guide part are relatively fixed and a water outlet cavity is formed between the two; the cover body is provided outside the end of the main body and a transmission cavity is formed between the cover body and the guide plate; the transmission connecting piece is sleeved on the outer peripheral edge of the guide plate, and the cover body is provided with a notch at the location of the transmission connecting piece, and the notch is located on the side of the cover body close to the water outlet cavity.

[0016] The side wall of the water outlet cavity connected to the water inlet channel is also provided with an axially protruding second limiting portion, and the second limiting portion extends radially along the water outlet cavity. When the two adjusting members move back to back and abut against the second limiting portion, the water outlet amplitude is maximum.

[0017] The invention also includes a sensing module, which is axially arranged in the body and located on the side of the water inlet channel away from the water outlet. The sensing module is provided with a sensing end, which is located at the end where the transmission cavity of the body is located.

[0018] A urinal comprises a urinal body, and is characterized in that it also comprises the above-mentioned nozzle with adjustable water outlet amplitude.

[0019] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, the adjustment assembly is arranged to be rotatable around the water inlet channel, and cooperates with the transmission component to make the two adjustment parts move towards or away from each other to adjust the water outlet amplitude of the water outlet, reduce the distance between the rotation axis of the adjustment structure and the axis center of the nozzle, reduce the radial occupied space, and increase the adjustable angle.

[0021] 2. In the present invention, the adjustment assembly and the transmission component are designed in an axial layered manner, and the transmission cavity is independently arranged behind the water outlet cavity, which reduces the radial space occupation and makes the overall structure more compact.

[0022] 3. In the present invention, the rotation support of the adjusting member is achieved through a coaxially nested sleeve structure, which maximizes the relative displacement within a limited space, thereby obtaining a larger opening and closing stroke and a wider water outlet amplitude adjustment range.

[0023] 4. In the present invention, the transmission connector adopts a combined design of a bending section and an extension section to achieve axial to radial spatial conversion, ensuring that the motion transmission between the adjustment component and the transmission component is not interfered with.

[0024] 5. In the present invention, the gear transmission structure is arranged in an independent transmission cavity, which is separated from the water outlet cavity, thereby improving the sealing performance and effectively preventing leakage problems caused by gear meshing clearance.

[0025] 6. In the present invention, a first limiting portion and a second limiting portion are provided to control the movement range of the adjusting member by mechanical contact, thereby ensuring that the water outlet amplitude is always kept within a preset range.

[0026] 7. In the present invention, a modular layered design is adopted to separate the water outlet guide layer from the angle adjustment transmission layer, thereby simplifying the structure and improving reliability; sufficient remaining space is reserved in the radial direction, providing a structural basis for the installation of the sensing module.

[0027] 8. In the present invention, the exposed transmission connector protrusion design allows the water outlet amplitude to be manually adjusted without tools, making the operation simple and quick.

[0028] 9. In the present invention, a notch is provided on the cover to expose the transmission connector, which not only maintains concealment but also provides operating space, facilitates adjustment and does not affect the overall appearance. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. DETAILED DESCRIPTION

[0046] The present invention is further described below through specific embodiments.

[0047] See also Figures 1 to 13 A nozzle with adjustable water outlet angle includes a main body 10, an adjustment assembly 20, and a transmission component 30. The main body 10 is provided with a water inlet channel 11a and a water outlet chamber 14 connected to the water inlet channel 11a. Water flows into the water outlet chamber 14 through the water inlet channel 11a. The adjustment assembly 20 includes two adjustment members 21 rotatably arranged around the water inlet channel 11a within the water outlet chamber 14. The two adjustment members 21 form a water outlet 14a between two ends away from the water inlet channel 11a. A water spray channel 28 is also formed between the two adjustment members 21, connecting the water inlet channel 11a and the water outlet 14a. Water flows through the water spray channel 28 and is sprayed out of the water outlet 14a. The transmission component 30 is connected to each of the two adjusting members 21. It is configured to move as one of the adjusting members 21 rotates, pushing the other adjusting member 21 in the opposite direction. This causes the two adjusting members 21 to move toward or away from each other, changing the distance between the ends of the adjusting members 21 facing away from the water inlet channel 11a. This adjusts the water flow amplitude of the water outlet 14a. The water flow amplitude is defined as the opening and closing angle a of the water outlet 14a formed by the relative movement of the two adjusting members 21.

[0048] Among them, the rotation axes of the two adjusting parts 21 are coaxially arranged, and their rotation axes are parallel to the central axis of the water inlet channel 11a, and the projection point of the rotation axis on the radial section of the water inlet channel 11a is located within the contour range of the water inlet channel 11a. This way of the rotation axis being within the range of the water inlet channel 11a enables the adjusting part 21 to rotate around the water inlet channel 11a, and the rotation axis does not need to occupy the space of the water outlet chamber 14, ensuring that the rotation of the adjusting part 21 will not block the water inlet channel 11a and will not interfere with its water spraying, thereby ensuring the water output and realizing the compact layout of the adjustment structure.

[0049] Furthermore, the motion trajectory of the end of the adjusting member 21 away from the water inlet channel 11a is designed to be a circular arc, with the projection of the arc's center onto a radial cross-section of the water inlet channel 11a falling within the contour of the channel 11a. This arc-shaped motion trajectory prevents the adjusting member 21 from extending outside the water outlet chamber 14 when rotated at different angles. Furthermore, the nearly circular arc design effectively reduces the radial dimensions of the water outlet chamber 14. This compact structural design reduces the overall radial footprint of the showerhead, thereby providing greater freedom in the design of the urinal's interior surface.

[0050] In actual application, the radial cross-section of the main body 10 adopts a circular design, and the projection point of the rotation axis of the adjustment member 21 on the radial cross-section of the water inlet channel 11a coincides with the center of the circle. This design further reduces the distance between the rotation axis and the main body axis, which not only reduces the radial space occupied by the adjustment component 20, but also increases the adjustable angle range of the water outlet 14a, while maintaining the simplicity and reliability of the structure. In the present invention, the main body 10 is also provided with a transmission chamber 15, which is located on the side of the water outlet chamber 14 facing away from the water inlet channel 11a. The ends of the two adjustment members 21 near the water outlet 14a are each provided with a transmission connector 22 extending to the transmission chamber 15; the transmission component 30 is arranged in the transmission chamber 15 and is transmission-connected to the two transmission connectors 22; by rotating the transmission connector 22 of any adjustment member 21, the transmission component 30 is driven to rotate in the opposite direction of the transmission connector 22 of the other adjustment member 21, so that the two adjustment members 21 move toward or away from each other to adjust the water outlet amplitude.

[0051] The adjustment assembly 20 and the transmission component 30 are designed in an axial layered manner, and the transmission chamber 15 is independently arranged behind the water outlet chamber 14, reducing the radial space occupied by the traditional parallel layout; the double adjustment member 21 is linked through the transmission connector 22 extending to the transmission chamber 15, avoiding interference of the transmission component 30 with the water inlet channel 11a.

[0052] The two adjusting members 21 are arranged radially along the water outlet chamber 14. The first opposite ends of the two adjusting members 21 are respectively provided with a shaft sleeve 23 extending axially along the water outlet chamber 14. The two shaft sleeves 23 are coaxially nested and then rotatably arranged in the water inlet channel 11a. The two shaft sleeves 23 have different diameters and are nested. They are assembled in the water inlet channel 11a in a coaxial nesting manner to form a compact rotating support structure. The two adjusting members 21 and the shaft sleeves 23 form an adjustable fan-shaped water spray channel that is sealed at the connection to prevent water leakage. The second end of the adjusting member 21 is close to the water outlet 14a and is provided with a transmission connector 22. This design achieves the maximum relative displacement of the adjusting member 21 in a limited radial space through coaxial rotation, and can obtain a larger opening and closing stroke. The nested structure of the two shaft sleeves 23 not only ensures the concentricity of the rotation of the adjusting member 21, but also avoids the space waste of the traditional parallel layout, providing a structural basis for expanding the water outlet amplitude adjustment range.

[0053] See also Figure 6 The transmission connector 22 includes a bent section 24 and an extension section 25. The bent section 24 is connected to the end of the adjustment assembly 20 near the water outlet 14a. Specifically, the bent section 24 originates at the second end of the adjustment member 21 and extends axially along the water outlet chamber 14 by a predetermined length to exit the water outlet chamber 14. The extension section 25 is connected to the bent section 24. Specifically, the extension section 25 extends radially from the end of the bent section 24 along the water outlet chamber 14 into the transmission chamber 15 to connect with the transmission component 30. This structure achieves rotational motion transmission between the adjustment assembly 20 and the transmission component 30 through axial-to-radial spatial conversion.

[0054] Furthermore, to facilitate the rotation of the transmission connector 22, a protrusion 27 is provided at a suitable location on at least one transmission connector 22, facilitating manual torque control of the rotation of the transmission connector 22. Specifically, the protrusion 27 can be formed on the outer periphery of the second end of the adjustment member 21 and / or on the side of the bent section 24 away from the water outlet chamber 14. The extension section 25 also has a first connecting portion 26, which is connected to the transmission component 30 via the first connecting portion 26.

[0055] The transmission component 30 of the present invention can adopt a single transmission arm connected between the transmission connectors 22 of the two adjustment members 21, and a corresponding limiting structure is set in conjunction with the main body 10 to limit the movement of the transmission arm in a predetermined direction. When one adjustment member 21 is pushed, the transmission arm moves in the predetermined direction and pushes the other adjustment member 21 to move in the opposite direction. Alternatively, two transmission members 31 are used in conjunction with a gear transmission method to realize transmission. Specifically, taking the transmission component 30 adopting a gear transmission method as an example, it includes two transmission members 31 arranged along the radial direction of the transmission chamber 15, and the first ends of the two transmission members 31 are provided with mutually meshing gears 32. The rotating shafts 12d of the two gears 32 are parallel to the axial direction of the transmission chamber 15. The gear 32 transmission structure is set in the transmission chamber 15 and separated from the water outlet chamber 14, so that the angle adjustment component of the water outlet chamber 14 can adopt a more rigorous sealing structure, effectively avoiding the leakage problem caused by the meshing gap of the gears 32.

[0056] The second ends of the two transmission members 31 are provided with a second connecting portion 33, which is used to connect to the first connecting portion 26 of the corresponding transmission connector 22. The first connecting portion 26 and the second connecting portion 33 can be implemented using a concave-convex fit or other similar structure. For example, the first connecting portion 26 is configured as a boss, and the second connecting portion 33 is configured as a slot. The rotatable connection is achieved by inserting the boss into the slot. The slot can be a U-shaped slot or a circular slot. When any transmission connector 22 is rotated, its rotational torque is transmitted to the corresponding transmission member 31 through the second connecting portion 33. After the mutually meshing gears 32 change the direction of motion, it drives the other transmission member 31 to rotate in the opposite direction, thereby driving the other transmission connector 22 to rotate in the opposite direction synchronously.

[0057] The transmission cavity 15 is also provided with an axially protruding first limiting portion 12a. The first limiting portion 12a is located between the two transmission members 31. When the two transmission members 31 move toward each other and abut against the first limiting portion 12a, the water discharge amplitude is minimized. The first limiting portion 12a is provided between the relative motion paths of the two transmission members 31. The first limiting portion 12a and the opposing end surfaces of the two transmission members 31 serve as stop surfaces 12b. When the two transmission members 31 move toward each other during the transmission process, when their end surfaces contact the stop surfaces 12b of the first limiting portion 12a, the relative displacement of the two transmission members 31 reaches the minimum spacing allowed by the design, i.e., the transmission members are in the minimum water discharge amplitude working state (e.g., 60°). See FIG. Figure 10 .

[0058] The side wall of the water outlet cavity 14 communicating with the water inlet channel 11a is further provided with an axially protruding second limiting portion 12c, which extends radially along the water outlet cavity 14. When the two adjusting members 21 move back to back and abut against the second limiting portion 12c, the water outlet amplitude is the largest (for example, 160°). Figure 12The present invention provides an axially protruding second stopper 12c on the sidewall of the connecting area between the outlet chamber 14 and the inlet channel 11a. This second stopper 12c extends radially along the outlet chamber 14 to form a mechanical barrier. When the two adjusting members 21 move in opposite directions until they contact the second stopper 12c, their displacement reaches the maximum stroke allowed by the design.

[0059] The present invention mechanically limits the movement of the adjusting member 21 toward and away from each other by providing a first limiter 12a and a second limiter 12c, respectively. The first limiter 12a defines the minimum travel of the adjusting member 21, while the second limiter 12c defines the maximum travel of the adjusting member 21. The synergistic action of these two limiters controls the range of motion of the adjusting member 21, ensuring that the water flow amplitude remains within a predetermined range, such as, but not limited to, 60°-160°. This mechanical contact approach to limiting the range of motion provides a simple and reliable structure.

[0060] The main body 10 is provided with a main body 11, a guide vane 12 and a cover 13. The main body 11 is provided with an axially extending water inlet channel 11a, which serves as a conveying path for the fluid medium. A guide portion 11c is provided at one axial end of the main body 11, and the guide portion 11 extends radially. The guide vane 12 is assembled to the axial end of the water inlet channel 11a, namely the guide portion 11c, by a fixed connection. The guide vane 12 and the guide portion 11c can be connected to each other by ultrasonic welding or other common fixing methods, and ensure that the rotational movement of the adjustment member 21 is not affected. There is a specific distance between the guide vane 12 and the guide portion 11c to form a water outlet chamber 14. A fan-shaped water spray channel 28 is formed between the two adjustment members 21 and the guide vane 12 and the guide portion 11c. The cover 13 serves as an external protective component and is installed on the outside of the end of the main body 11 in a hood-type manner. The cover 13 and the main body 11 can be fixed by screw locking or threaded fitting. A transmission cavity 15 is formed between the inner wall of the cover 13 and the guide plate 12 .

[0061] Through holes 34 are provided on the gears 32 of the two transmission members 31. Two rotating shafts 12d are provided on the side wall where the transmission cavity 15 of the guide vane 12 is located, near the relative position of the shaft sleeve 23 of the adjustment member 21. The through holes 34 of the gears 32 can be rotatably sleeved on the rotating shafts 12d to achieve rotational connection. The transmission connector 22 is sleeved on the outer edge of the guide vane 12. The cover body 13 is provided with a notch 13a where the transmission connector 22 is located. The notch 13a is located on the side of the cover body 13 close to the water outlet cavity 14 and is highly concealed. The notch 13a is provided to expose the transmission connector 22 and provide the necessary operating space for the transmission connector 22. The angle can be directly adjusted without removing the cover body 13. In actual application, the notch 13a can be provided on the cover body 13 at the positions of both transmission connectors 22, or at the position of one of the transmission connectors 22.

[0062] In the present invention, in the radial direction of the main body 10, the guide plate 12, the water outlet chamber 14 and the transmission chamber 15 only occupy a local space, and sufficient remaining space is reserved in the radial direction, providing a structural basis for the installation of the sensing module 50. The sensing module 50 is axially arranged in the main body 10 and is located on the side of the water inlet channel 11a away from the water outlet 14a. In specific implementation, the sensing module 50 is positioned and installed through the radial mounting hole 11b provided on the main body 11. The mounting hole 11b is located in the remaining space of the main body 10 except the water outlet chamber 14 and the transmission chamber 15. The sensing module 50 and the main body 11 can be fixed with a concave and convex snap-on type to ensure a stable and secure installation. The sensing module 50 is internally integrated with a signal detection functional unit, and its sensing end 51 extends to the end where the transmission chamber 15 is located, and is finally positioned at a specific position on the cover body 13. An assembly hole is provided on the cover body 13 to install the sensing end 51. The spatial layout and connection relationship between each component have been rationally designed to ensure the functional realization while achieving the compact structure and easy assembly.

[0063] Based on this, see Figure 14 The present invention also provides a urinal comprising a urinal body 40 and the aforementioned adjustable-flow showerhead. The showerhead body 11 is inserted into the mounting hole. A nut 41, washer 42, and rubber pad 43 are fitted onto the body to secure the showerhead. The water outlet 14a, cover 13, and sensor 51 are positioned toward the toilet bowl. The showerhead's water inlet channel 11a is connected to a water supply pipe, which is controlled by a solenoid valve to open or close the water supply.

[0064] After the showerhead of the present invention is installed on the urinal body 40, to adjust the water flow rate, the protrusion 27 on any transmission connector 22 is manipulated to rotate the transmission connector 22. The rotational torque is transmitted to the corresponding transmission member 31. After the mutually meshing gears 32 change the direction of movement, the other transmission member 31 is driven to rotate in the opposite direction, thereby causing the other transmission connector 22 to rotate in the opposite direction synchronously, thereby adjusting the water flow rate.

[0065] In this invention, the outlet cavity 14 and adjustment assembly 20 form the water outlet diversion layer, while the transmission cavity 15 and transmission component 30 form the angle adjustment transmission layer. This modular layered design allows for tool-free adjustment, enabling convenient adjustment of the urinal showerhead's water outlet amplitude. The sensing end 51 of the sensor module 50 extends to the end of the transmission cavity 15 and is used to detect the showerhead's operating status.
