Description

Technical Field

[0001] The present invention relates to the field of sanitation, and more particularly to a water discharge device.

Background Art

[0002] Conventional sanitary water discharge devices such as multifunctional foamers, faucet heads or showers are generally provided with components such as a rotatable housing, a push-pull mandrel, or a push button to generate different forms of water discharge shapes and switch the water discharge path in the water discharge device.

[0003] Generally, the above water discharge device requires active operation to obtain the necessary water discharge state for the user. And the user may forget how the water discharge device was switched to the previous water discharge state by the previous operation until the next time the water discharge device is turned on after use. The user cannot specify what water discharge shape the water discharge device generates. Therefore, there is a risk that an inappropriate water discharge shape will collide with the use environment and splash.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The technical problem to be solved by the present invention is to provide a water discharge device that can return to the initial water discharge state when the water flow is stopped.

Means for Solving the Problems

[0005] In order to solve the above technical problem, the technical solution adopted by the present invention is as follows.

[0006] The water discharge device includes a water passage section and a water discharge section, wherein the water passage section has a plurality of jet holes in the circumferential direction, the water discharge section has different water flow paths, the water passage section and the water discharge section are rotatably connected, the jet holes communicate with the different water flow paths as the water passage section and the water discharge section rotate relative to each other, the water passage section has a first position limiting section in the axial direction, the water discharge section has a first support section in the axial direction, and further includes a slider and an elastic means, the slider has a second support The device includes a support portion and a second position limiting portion, the first position limiting portion being connected to the second position limiting portion of the slider such that the slider is movable only along the axial direction of the water discharge portion, the elastic means supporting the slider in the axial direction, the second support portion of the slider being in contact with or separated from the first support portion in the axial direction, and the slider and the water discharge portion communicating with each other through different water flow paths and jet holes as the second support portion and the first support portion rotate relative to each other.

[0007] The water discharge device according to the present invention is used by being attached to a faucet directed towards a kitchen or toilet. When water flows from the faucet, the water flow is ejected from the jet hole into the water flow path, and as it leaves the water discharge device from the water flow path, it creates a first type of water discharge shape. At the same time, the water flow causes the slider to move synchronously along the axial direction of the first mounting through hole in the water discharge direction, and the second support part of the slider separates from the first support part of the water discharge part, while the elastic means accumulates elasticity. When water passes through, rotating the water discharge part makes it possible to align the other water flow path with the jet hole, causing the water flow to leave the water discharge device from the other water flow path and form a second type of water discharge shape. At the same time, this rotation also causes the first support part of the water discharge part to rotate toward the second support part of the slider, so that the two come into close proximity or contact with each other. If the water supply is stopped while the second type of water discharge shape is being generated, the elastic means releases its elasticity and returns to the initial state. In this process, the slider moves axially in the water supply direction by an elastic means, pressing the second support portion of the slider against the first support portion. The axial motion of the slider is converted into circumferential rotation of the water discharge portion by the contact of the second support portion against the first support portion, and the water discharge portion returns to its initial circumferential position until the slider returns to its initial axial position. [Effects of the Invention]

[0008] The beneficial effects of the present invention are as follows: Regardless of the water flow state or shape that occurs during use, the water dispensing device returns to its initial state when the water flow is stopped due to the operation of its internal components. This makes it easier for users to understand what shape of water will occur each time they use the device, thereby improving their experience of using the water dispensing device.

[Modes for carrying out the invention]

[0010] To explain in detail the technical content, objectives, and effects of the present invention, the following description will be provided with reference to the drawings and embodiments.

[0011] Referring to Figures 1 to 13, the water discharge device includes a water passage section 10 and a water discharge section 20. The water passage section 10 is provided with a plurality of jet holes 11 in the circumferential direction, and specifically, a plurality of jet holes 11 distributed in the circumferential direction on the axial end face of the water passage section 10 are installed. The water discharge section 20 is provided with different water flow paths, and the water passage section 10 and the water discharge section 20 are rotatably connected. The jet holes 11 communicate with the different water flow paths as the water passage section 10 and the water discharge section 20 rotate relative to each other. The water passage section 10 is provided with a first mounting through hole 12 along the axial direction. The first mounting through hole 12 is provided with a first position limiting portion 121 along the axial direction on its inner wall. The water discharge section 20 is provided with a second mounting through hole 21 along the axial direction. The second mounting through hole 21 is provided with a first support portion 211 on its inner wall. The water discharge device includes a slider 31 and an elastic means 32. The slider 31 includes a second support portion 311 and a second position limiting portion 312. The slider 31 is provided in a first mounting through hole 12 of the water passage portion 10. The first position limiting portion 121 in the first mounting through hole 12 is connected to the second position limiting portion 312 of the slider 31, so that the slider 31 can move in the first mounting through hole 12 only along the axial direction. The elastic means 32 supports the slider 31 in the axial direction. The water passage portion 10 is attached to the second mounting through hole 21 of the water discharge portion 20 by passing through the first mounting through hole 12. The second support portion 311 of the slider 31 is in contact with or separated from the first support portion 211 of the second mounting through hole 21 in the axial direction, and the slider 31 and the water discharge portion 20 can communicate with each other through different water flow paths and jet holes 11 by the relative rotation of the second support portion 311 and the first support portion 211.

[0012] When no water is flowing from the faucet, the jet hole 11 aligns with the water flow path, the second support portion 311 of the slider 31 is sufficiently close to or in contact with the first support portion 211 of the water discharge portion 20, and the slider 31 is in a stable position due to the support of the elastic means 32. When water is flowing from the faucet, the slider 31 is subjected to water pressure, and if the water pressure is greater than the elasticity of the elastic means 32, the slider 31 moves axially through the first mounting through hole 12 in the direction of water discharge. This movement causes the second support portion 311 of the slider 31 and the first support portion 211 of the water discharge portion 20 to separate. The elastic means 32 is in a state of accumulating elasticity, and at the same time, the water flow passes through the jet hole 11 and is ejected into the water flow path, leaving the water discharge device from the water flow path, and the first type of water discharge shape is generated. When water is flowing, the user rotates the water outlet 20 (in this case, it may be defined as the water outlet 20 rotating in the first direction), causing the other water flow path to align with the jet hole 11, and the water flow to separate from the water outlet device from that water flow path, resulting in a second type of water discharge shape. The rotation of the water outlet 20 also causes the first support portion 211 of the water outlet 20 to rotate toward the second support portion 311 of the slider 31, bringing the local parts of the two into close proximity or contact. Due to the sustained role of water pressure, the elastic means 32 continuously maintains a state of accumulating elasticity. When the water flow is closed and the water supply to the faucet is stopped while the second type of water discharge shape is generated, the elastic means 32 loses its restriction due to water pressure, releases its elasticity, and returns to its initial state. As the elastic means 32 returns to its initial state, the slider 31 moves axially toward the water supply direction due to its elasticity, and the second support portion 311 of the slider 31 presses against the first support portion 211 while contacting it, causing it to rotate. The axial motion of the slider 31 is converted from pressing against the first support 211 by the second support 311 to circumferential rotation of the water discharge section 20 (at this time, the water discharge section 20 rotates in a second direction opposite to the first direction). When the slider 31 returns to its initial axial position, the water discharge section 20 also returns to its initial circumferential position.

[0013] It is understood that, when no water is flowing, even if the second support portion 311 and the first support portion 211 are in their initial positions, they are sufficiently close to or in contact with each other, and the water discharge portion 20 is rotatable by external force (in all embodiments, the water discharge portion 20 is not locked). However, in this state, in order to rotate the water discharge portion 20, it is necessary to overcome the support force of the elastic means 32. In other words, when an external force is applied to the water discharge portion 20, the first support portion 211 drives the slider 31, overcoming the support force of the elastic means 32 and moving to the water discharge end of the first mounting through hole 12, the water discharge portion 20 rotates to its final position, and if the external force is not maintained, the water discharge portion 20 cannot be kept in the switched position. When the external force is removed, the elastic means 32 drives the slider 31 back to its initial position, and the water discharge portion 20 moves in conjunction to return to its initial position. The elastic means 32 in this application may be a compression spring or a torsion spring.

[0014] In some embodiments, the water flow paths are provided in only two groups, with inlets for the two groups of water flow paths provided on the water supply side of the discharge section 20, and the inlets for the first group of water flow paths 23 and the second group of water flow paths 24 are arranged in a staggered pattern. The discharge section 20 has outlets for the two groups of water flow paths on the discharge side. The outlet of the first group of water flow paths 23 is enclosed by the outlet of the second group of water flow paths 24. In such an arrangement, water discharge is realized in both the inner and outer rings, that is, at the outlet of the first group of water flow paths 23, the discharge section 20 has a relatively large discharge surface and generates a clustered shape, which is water consisting of bubbles, clear water, spray water, sheet-like water, or shower water consisting of multiple thin water columns. The second water flow path 24 has a discharge section 20 at its outlet with a relatively small discharge area, generating a ring-shaped flow around the axis of the discharge section 20. This ring-shaped flow around the axis may be a typical shower stream or a shower stream consisting of multiple thin water columns. The ring-shaped water may also be high-pressure water.

[0015] In some embodiments, the slider 31 appears at the opening of one end on the water supply side in the first mounting through hole 12 on the top surface. When water is flowing, all the water pressure is received by the top surface of the slider 31, overcoming the elastic force of the elastic means 32, and the slider 31 smoothly moves axially in the water discharge direction through the first mounting through hole 12, and the second support portion 311 of the slider 31 disengages from the first support portion 211 in the water discharge portion 20, ensuring that the water discharge portion 20 can rotate without hindrance and can maintain its position even when rotated.

[0016] In some embodiments, it further includes a water discharge panel connected to the water discharge end of the water discharge portion 20. By interposing the elastic means 32 between the slider 31 and the water discharge panel, when there is no external force acting (here, the external force includes the pressure due to water pressure and the force from the person rotating the water discharge portion 20), the two can maintain stability in the relative position. That is, the slider 31 is located in the first mounting through hole 12 at a position away from the water discharge end in the first mounting through hole 12, and its second support portion 311 abuts against the first support portion 211.

[0017] In some embodiments, by providing a sealing portion 33 between the slider 31 and the first mounting through hole 12, it is possible to avoid the situation where when water flows, the water flow overflows from between the slider 31 and the first mounting through hole 12, and finally the discharged water shape is deformed or becomes water droplets. The sealing portion 33 may be an O-ring seal, but a Y-ring seal is more preferable.

[0018] In some embodiments, at least one of the first support portion 211 and the second support portion 311 is similar to a column. Preferably, at least one of the first support portion 211 and the second support portion 311 is a wedge shape or a cuboid. In order to realize that the slider 31 moves axially through the first mounting through hole 12 and at the same time the water discharge portion 20 is driven to rotate in the circumferential direction, when using the design of a structure similar to a column, a wedge shape or a cuboid for the support portion, a mechanism in the shape of a wedge can be configured between the two to convert linear motion into rotational motion. That is, the first support portion 211 is located on one side close to the water supply direction, the second support portion 311 is located on one side close to the water discharge direction, the second support portion 311 supports the first support portion 211, and the axial movement of the slider 31 can be changed into the circumferential rotation of the water discharge portion 20. Such a design has the highest efficiency in power transmission, a simple structure, and excellent stability.

[0019] In some embodiments, the first position limiting portion 121 and the second position limiting portion 312 are fitted to each other. Specifically, they are combined by a concave groove and a convex ridge. Either one of the two position limiting portions may be installed as a concave groove and the other as a convex ridge. Such a design can ensure that the slider 31 moves precisely along the axial direction and can ensure that the slider 31 accurately drives the water discharge portion 20 to rotate without itself generating rotation, with high power transmission efficiency and can improve the reliability of the product.

[0020] In some embodiments, the first mounting through hole 12 is provided with a notch 122 on the side wall, and the first support portion 211 extends from the notch 122 into the first mounting through hole 12. And it can be ensured that when the first support portion 211 and the second support portion 311 are combined and operate, it is easier for them to contact and abut against each other.

[0021] In some embodiments, a first position limiting plate 13 is provided on the water passage section 10, and a second position limiting plate 22 is provided on the water discharge section 20. The first position limiting plate 13 and the second position limiting plate 22 have overlapping movement trajectories in the circumferential direction, and the first position limiting plate 13 can come into contact with or separate from the second position limiting plate 22 as the water passage section 10 and the water discharge section 20 rotate relative to each other. Installing two position limiting plates limits the angle at which the water discharge section 20 rotates relative to the water passage section 10. Designing this angle ensures that, when the two position limiting plates are in contact with each other, the projections of the multiple jet holes 11 in the water passage section 10 are placed on the water discharge section 20 in the axial direction and fall into the inlets of different water flow paths. As a result, even when the water passage section 10 and the water discharge section 20 are located at different rotation limit positions, it is possible to ensure that the water flow ejected from the injection hole 11 enters the corresponding water flow path at that time, and that the water flow ultimately passes through the water flow path before being output to the outside.

[0022] In some embodiments, the water passage section 10 is provided with a protrusion 14 on the outside of the hole wall in the first mounting through hole 12. The water discharge section 20 is connected to the water passage section 10 with the protrusion 14 abutting against the bottom side of the hole wall in the second mounting through hole 21. Such a configuration is relatively simple yet stable, and by rotating the water discharge section 20 over the water passage section 10, it is possible to switch the communication between different water flow paths in the jet hole 11 and the water discharge section 20.

[0023] In some embodiments, the slider 31 is an integrated unit.

[0024] In some embodiments, the slider 31 has a detachable configuration. When the slider 31 has a detachable configuration, the slider 31 includes a pressure receiving portion 313 and a sliding portion 314, a second support portion 311 and a second position limiting portion 312 are installed on the sliding portion 314, the pressure receiving portion 313 is attached to the sliding portion 314, the pressure receiving end face of the pressure receiving portion 313 is located at the water supply end of the water passage portion 10, the sliding portion 314 is located at the water discharge end of the first mounting through hole 12 which is close to the water passage portion 10, and the elastic means 32 and the sliding portion 314 are in contact with each other. The above-described split configuration simplifies installation. Specifically, when installing, the water passage section 10 is first attached to the water discharge section 20, then the pressure receiving section 313 is attached to the first mounting through-hole 12 from one side of the water passage section 10, and then the sliding section 314 is attached to the first mounting through-hole 12 from one side of the water discharge section 20. When attaching the sliding section 314, it is necessary to simultaneously ensure that the second support section 311 is aligned with the first support section 211 and that the sliding section 314 and the pressure receiving section 313 are fitted together. The pressure receiving section 313 is for receiving pressure from the water flow, and it is necessary to install it so that the surface facing the water flow is as large as possible. When the pressure receiving section 313 is in its highest position, it is aligned with the first mounting through-hole 12, and the area of ​​the surface facing the water flow is installed so that it is as close as possible to the opening area of ​​the first mounting through-hole 12. When the pressure receiving section 313 is in the lowest position, it is positioned higher than the first mounting through hole 12, and the radius of the surface facing the water flow is set to be as close as possible to the distance from the center of the water passage section 10 to the injection hole 11.

[0025] Referring to Figures 1 to 13, the first embodiment of the present invention is as follows.

[0026] The water discharge device may be used as a foaming device attached to a faucet, and includes a water passage section 10 and a water discharge section 20. The water passage section 10 has a plurality of jet holes 11 arranged in the circumferential direction, and a first mounting through hole 12 arranged in the axial direction. One surface of the first mounting through hole 12 extends toward the water discharge direction, and an opening is provided on one side of the other surface toward the water supply direction. The first mounting through hole 12 has a first position limiting section 121 that exhibits a convex shape on its inner wall and is installed to extend in the axial direction. The water passage section 10 has a convex protrusion 14 extending radially on its outer wall. The water discharge section 20 is provided with different water flow paths. The water discharge section 20 has a second mounting through hole 21 arranged in the axial direction at its center. The inlet of the different water flow path goes around to the second mounting through hole 21, and a first support section 211 is provided on the hole wall of the second mounting through hole 21. The discharge section 20 is connected to the water passage section 10 so as to be rotatable relative to it, by contacting the protrusion 14 on the outer wall of the first mounting through hole 12 in the water passage section 10 through the discharge end of the second mounting through hole 21. The jet holes 11 communicate with different water flow paths as the water passage section 10 and the discharge section 20 rotate relative to each other. The number of jet holes 11 is half the sum of the number of inlets for all water flow paths.

[0027] In this embodiment, only two groups of water flow paths are provided, and only two groups of water flow path inlets are provided on the water supply side of the water discharge section 20. Each group of water flow paths has only eight inlets, and the inlets of the first group of water flow paths 23 and the inlets of the second group of water flow paths 24 are arranged in a staggered pattern. The water discharge section 20 has outlets for only two groups of water flow paths on the water discharge side, and the outlet of the first group of water flow paths 23 is enclosed by the outlet of the second group of water flow paths 24. With this setup, water discharge is realized in both the inner and outer rings. That is, at the outlet of the first group of water flow paths 23, the water discharge section 20 generates a clustered shape with a relatively large discharge area, while at the outlet of the second group of water flow paths 24, the water discharge section 20 generates a ring-shaped shape with a relatively small discharge area around the center. However, the clustered shape is bubble water, and the ring-shaped shape around the center is a shower water flow consisting of a thin shape with only a few columns.

[0028] The water passage section 10 has a first position limiting plate 13 on its outer wall, and the water discharge section 20 has a second position limiting plate 22 on its outer wall, with a circumferential rotation space between the first position limiting plate 13 and the second position limiting plate 22. The first position limiting plate 13 and the second position limiting plate 22 have overlapping movement trajectories in the circumferential direction, and the first position limiting plate 13 rotates relative to the water discharge section 20 by the water passage section 10, and is in contact with or separated from the second position limiting plate 22. When the first position limiting plate 13 and the second position limiting plate 22 are in contact at only two places, the jet holes 11 will align perfectly with the inlets of different water flow paths.

[0029] The water passage section 10 is provided with a slider 31 and an elastic means 32 sequentially in the first mounting through hole 12 along the water discharge direction. The elastic means 32 is provided in the first group water flow path 23 and supports the slider 31. The top surface of the slider 31 appears outside the water supply end of the first mounting through hole 12. A sealing section 33 is provided between the slider 31 and the first mounting through hole 12. The first mounting through hole 12 also has a notch 122 in its side wall, and the first support section 211 extends radially into the first mounting through hole 12 via the notch 122.

[0030] The slider 31 has a sectional configuration. The slider 31 includes a pressure receiving portion 313 and a sliding portion 314. The second support portion 311 and the second position limiting portion 312 are installed on the sliding portion 314, and the pressure receiving portion 313 is attached to the sliding portion 314. The pressure receiving end face of the pressure receiving portion 313 is located at the water supply end of the water passage portion 10, and the sliding portion 314 is located at the water discharge end of the first mounting through hole 12 which is close to the water passage portion 10. The elastic means 32 and the sliding portion 314 are in contact, and when the pressure receiving portion 313 is in its highest position, it is aligned with the first mounting through hole 12, and the area of ​​the pressure receiving end face of the pressure receiving portion 313 is smaller than the opening area of ​​the first mounting through hole 12.

[0031] When the slider 31 is attached to the first mounting through hole 12, its second position limiting portion 312 and the first position limiting portion 121 of the first mounting through hole 12 are fitted together by a combination of recessed grooves and protrusions in the axial direction, ensuring that the slider 31 can move only in the axial direction but cannot rotate circumferentially relative to the water passage portion 10. In addition, when the slider 31 is in the lowest position in the first mounting through hole 12, the bottom of the side wall of the pressure receiving portion 313 can come into contact with the tip of the first position limiting portion 121, thereby ensuring that the slider 31 does not fall out of the first mounting through hole 12. At the same time, the first support portion 211 of the water discharge portion 20 supports the second support portion 311 of the slider 31, and both the first support portion 211 and the second support portion 311 are wedge-shaped. The first support portion 211 and the second support portion 311 constitute a wedge-shaped power transmission mechanism, and both are capable of relative movement in the circumferential and axial directions of the water discharge portion 20 along the wedge-shaped inclination. Specifically, when the wedge-shaped inclination of the first support portion 211 faces the water discharge direction and the wedge-shaped inclination of the second support portion 311 faces the water supply direction, and neither the slider 31 nor the water discharge portion 20 receives water pressure, the second support portion 311 can always be in contact with the first support portion 211 by supporting the slider 31 with the elastic means 32. The wedge-shaped power transmission mechanism is such that when the slider 31 moves axially due to an external force, the water discharge portion 20 rotates in the circumferential direction, or when the water discharge portion 20 rotates circumferentially, the slider 31 moves in the axial direction.

Any equivalent substitutions obtained using the contents described in the specification and drawings of the present invention, or any application directly or indirectly to the relevant art, should likewise be included within the scope of the claims of the present invention.
