Description

Technical Field

[0001] The utility model relates to the technical field of bathroom products, in particular to a water outlet switching device. Background Art

[0002] Currently, there is a switching device provided on the shower head that can be used to switch the water outlet, so as to realize the switching of water outlets to different water outlets;

[0003] The more common switching operation methods are: pressing a button multiple times to realize cyclic switching of water outlet routes between multiple gears, that is, each time a button is pressed, it switches to the next gear. This method cannot guarantee that the water route desired by the user will be switched in one operation, and the operation is not convenient enough; setting multiple buttons and switching to the corresponding water outlet route by pressing different buttons has a more complicated structure and requires the user to operate different buttons in different positions, which is also not convenient enough.

[0004] Currently, there is a need for a water outlet switching device that is more convenient to operate. Utility Model Content

[0005] The purpose of the utility model is to provide a water outlet switching device, and the technical problem to be solved is how to make the water outlet switching operation more convenient.

[0006] In order to achieve the above objectives, the solution of the present invention is:

[0007] A water outlet switching device comprises a valve housing, a water distribution plate, a separator and a valve stem;

[0008] A valve cavity is formed in the valve housing, and the valve cavity has a water inlet and at least one water outlet connected to the outside of the valve housing. A water outlet surface is formed on the inner wall of the valve cavity, and the water outlets are all located on the water outlet surface.

[0009] The water distribution plate is attached to the water outlet surface, and a water distribution port is passed through the water distribution plate. The water flow entering the valve cavity from the water inlet is located on the side of the water distribution plate facing away from the water outlet surface.

[0010] The separator is fixedly arranged in the valve cavity, extending and fitting to the side of the water distribution plate facing away from the water outlet surface;

[0011] A ball head is formed in the middle of the valve stem, and the ball head is clamped between the inner wall of the valve cavity and the top surface of the partition to form a ball head hinge structure. One end of the valve stem extends out of the valve housing, and the other end of the valve stem cooperates with the water diversion plate as a hole column. A hole column cooperation structure is formed on the side of the water diversion plate facing away from the water outlet surface, so that when it swings, the water diversion plate is driven to slide on the water outlet surface, so that the water diversion port is aligned with different positions on the water outlet surface, so that the water diversion port can be docked or misaligned with at least one water outlet.

[0012] Furthermore, when the water diversion plate slides on the water outlet surface, it can slide to the point where the water diversion port is simultaneously offset to each water outlet, or docked to at least one water outlet;

[0013] Alternatively, when the water diversion plate slides on the water outlet surface, the water diversion port is only used for switching and docking with different water outlets.

[0014] Furthermore, the valve stem is located on the side of the water diversion plate facing away from the water outlet surface, and a plurality of water outlets and a water stop are provided on the water outlet surface. The water stop is used to seal the water diversion outlets. The water stop and the water outlets are arranged around the valve stem. When the valve stem is perpendicular to the water diversion plate, the water diversion outlet is aligned with the center of the arrangement position of each water outlet and the water stop.

[0015] Furthermore, an elastic member is provided, which is located in the valve cavity and elastically pressed against the side of the water diversion plate facing away from the water outlet surface, so as to form a water seal between the water diversion plate and the water outlet surface.

[0016] Furthermore, a valve stem through-hole is formed on the water diversion plate, and the valve stem is inserted into the valve stem through-hole from the side of the water diversion plate facing away from the water outlet surface, and cooperates with the gap of the valve stem through-hole to form a hole-column matching structure, thereby being able to drive the water diversion plate to slide on the water outlet surface.

[0017] Furthermore, the middle portion of the valve stem through-hole is inwardly retracted, and both ends gradually expand outwardly from the middle portion into a trumpet shape, and the valve stem passes through the middle portion of the valve stem through-hole.

[0018] Furthermore, a fixed valve plate is installed on the inner wall of the valve cavity, and the water outlet surface is located on the fixed valve plate.

[0019] Furthermore, the water outlet surface is a plane, and the partition extends and fits to the side of the water diversion tray that is away from the water outlet surface. Furthermore, the water outlet surface is a concave spherical surface.

[0020] Furthermore, the center of the concave spherical surface of the water outlet surface is consistent with the center of the ball head.

[0021] Furthermore, a button is provided, which is located at one end of the valve stem extending out of the valve housing. The button is disc-shaped, perpendicular to the valve stem, with its center fixed on the valve stem and extending outward on all sides.

[0022] After adopting the above solution, the beneficial effects of the utility model are:

[0023] (1) A valve cavity is formed in the valve housing, and the valve cavity has a water inlet and at least one water outlet that are connected to the outside of the valve housing. A water outlet surface is formed on the inner wall of the valve cavity, and the water outlets are all located on the water outlet surface. The water distribution plate is attached to the water outlet surface, and the water distribution plate is penetrated by the water distribution plate. The middle part of the valve stem is spherically hinged on the valve housing, one end of the valve stem extends out of the valve housing, and the other end is matched with the water distribution plate, so that when it swings, the water distribution plate is driven to slide on the water outlet surface, so that the water distribution outlet is aligned with different positions on the water outlet surface. Therefore, by pressing the button in the corresponding direction to shake the valve stem to the corresponding direction, the water distribution outlet can be connected to the corresponding water outlet, or misplaced to the corresponding water outlet, so as to switch the water outlet, which is more convenient to operate;

[0024] (2) The water flow entering the valve cavity from the water inlet is located on the side of the water distribution plate facing away from the water outlet surface. The water pressure acts on the side of the water distribution plate facing away from the water outlet surface, pressing the water distribution plate onto the water outlet surface. The greater the water pressure, the greater the pressure, which helps to form a water seal between the water distribution plate and the water outlet surface.

[0025] (3) When the water pressure is low, the water separator is pressed against the water outlet surface by the elastic member to form a water seal. When the water pressure increases, the water separator is pushed against the water outlet surface by the water pressure to strengthen the water seal, thereby minimizing the resistance of the water separator sliding on the water outlet surface, making it easier to operate the valve stem for swinging.

[0026] (4) By separating the ball head from the water distribution plate, not only a floating seal is achieved, but also the ball head is miniaturized, which further reduces the space of the mechanism and is more conducive to being installed on a smaller bathroom water outlet device.

DETAILED DESCRIPTION

[0036] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] In the claims, specification and the above-mentioned drawings of the present invention, unless otherwise expressly defined, directional words, such as the use of terms such as "center", "transverse", "longitudinal", "horizontal", "vertical", "top", "bottom", "inside", "outside", "up", "down", "front", "back", "left", "right", "clockwise", "counterclockwise" and the like to indicate directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, so they cannot be understood as limiting the specific scope of protection of the present invention.

[0038] The utility model provides a water outlet switching device, and provides the following two specific embodiments:

[0039] Example 1

[0040] like Figure 1-6As shown, it includes a valve housing 1, a water distribution plate 2, a separator 14, a valve stem 4 and an elastic member 3; a valve cavity 5 is formed in the valve housing 1, and the valve cavity 5 has a water inlet 6 and at least one water outlet 7 leading to the outside of the valve housing 1. The number of the water inlet 6 and the water outlet 7 is not specifically limited. A water outlet surface 8 is formed on the inner wall of the valve cavity 5, and the water outlets 7 are all located on the water outlet surface 8. In this embodiment, the water outlet surface 8 is a plane. Of course, in other embodiments, it can also be other non-planar shapes; the water distribution plate 2 is attached to the water outlet surface 8, and the water distribution plate 2 is penetrated by a water distribution port 9; the separator 14 is fixedly arranged in the valve cavity 5, extending and attached to the back of the water distribution plate 2 The shape of one side of the water outlet surface 8 is not specifically limited, as long as it does not completely block the water flow and can limit the water diversion plate 2 from turning over and moving in its direction; the elastic member 3 is located in the valve cavity 5 and is elastically pressed against the side of the water diversion plate 2 facing away from the water outlet surface 8. The pressure of the elastic member 3 on the water diversion plate 2 is set so that when the water pressure in the valve cavity 5 is low, a water seal can be formed between the water diversion plate 2 and the water outlet surface 8 (the water seal mentioned in this article refers to preventing water from entering between the water diversion plate 2 and the water outlet surface 8). The setting position of the water inlet 6 satisfies the requirement that the water flow entering the valve cavity 5 from the water inlet 6 flows into the water diversion plate 2 facing away from the water outlet surface 8. On one side of the water outlet surface 8, the water diverter disc 2 can be pushed toward the water outlet surface 8 by water pressure, and as the water pressure in the valve chamber 5 increases, the pressure of the water diverter disc 2 on the water outlet surface 8 also increases accordingly, so that when the water pressure in the valve chamber 5 increases, a water seal is formed between the water diverter disc 2 and the water outlet surface 8; the valve stem 4 is located on the side of the water diverter disc 2 facing away from the water outlet surface 8, and a ball head 22 is formed in the middle of the valve stem 4. The ball head 22 is clamped between the inner wall of the valve chamber 5 and the top surface of the partition 14 (referring to the side of the partition facing away from the water diverter disc) to form a ball head hinge structure. The top end of the valve stem 4 extends out of the valve housing 1 and has a button 11, which is in the shape of a disk. shaped, perpendicular to the valve stem 4, with the center position fixed on the valve stem 4 and extending outward on all sides, and then by pressing different positions of the edge of the button 11, the valve stem 4 can be driven to swing accordingly, which is convenient and labor-saving to operate. The bottom end of the valve stem 4 extends into the valve cavity 5 and movably cooperates with the water diversion plate 2. The structure of the movable cooperation is not specifically limited. The preferred embodiment is given later. As long as the bottom end of the valve stem 4 is swung in one direction, the water diversion plate 2 can be driven to slide synchronously in that direction, so that the water diversion port 9 is aligned with different positions on the water outlet surface 8, so that the water diversion port 9 can be docked or misaligned with at least one water outlet 7.

[0041] The setting of the water outlet 7 can be the following two more specific implementation methods: Implementation method 1, when the water diversion plate 2 slides on the water outlet surface 8, it can slide to make the water diversion port 9 simultaneously offset to each water outlet 7 to stop water, or dock with at least one water outlet 7 to start water outlet. In the scheme where multiple water outlets 7 are set, water outlet can also be switched by docking with different water outlets 7; Implementation method 2, when the water diversion plate 2 slides on the water outlet surface 8, the water diversion port 9 is only used to switch and dock with different water outlets 7, and is only used for water outlet switching.

[0042] Preferably, a plurality of water outlets 7 and a water stop 10 are provided on the water outlet surface. The water stop 10 is used to block the water diversion port 9. The water stop 10 and the water outlets 7 are arranged around the valve stem 4. When the valve stem 4 is perpendicular to the water diversion disk 2, the water diversion port 9 is aligned with the center of the arrangement position of the water outlet 7 and the water stop 10. Then, by pushing the valve stem 4 from the middle position (the position perpendicular to the water diversion disk 2) in different directions, the corresponding water outlet mode is switched or the water outlet is turned off, which makes the operation clearer.

[0043] In a more specific embodiment, the water outlet 7 is more specifically three, namely the first water outlet 15, the second water outlet 16 and the third water outlet 17. When the valve stem 4 is in the middle position, the water outlet 9 is simultaneously connected to the first water outlet 15, the second water outlet 16 and the third water outlet 17. The arrangement positions of the three water outlets 7 and the water stop 10 are specifically such that when the front of the button 11 is pressed, the end of the valve stem 4 outside the valve cavity 5 swings forward, while the end inside the valve cavity 5 swings backward, driving the water diversion plate 2 to slide backward, so that the water diversion port 9 only docks with the water stop 10. When the rear of the button 11 is pressed , the end of the valve stem 4 located outside the valve cavity 5 swings backward, and the end located inside the valve cavity 5 swings forward, driving the water diversion plate 5 to slide forward, so that the water diversion port 9 only connects to the first water outlet 15. When the left part of the button 11 is pressed, the end of the valve stem 4 located outside the valve cavity 5 swings left, and the end located inside the valve cavity 5 swings right, driving the water diversion plate 5 to slide right, so that the water diversion port 9 only connects to the second water outlet 16. When the right part of the button 11 is pressed, the end of the valve stem 4 located outside the valve cavity 5 swings right, and the end located inside the valve cavity 5 swings left, driving the water diversion plate 5 to slide left, so that the water diversion port 9 only connects to the third water outlet 17.

[0044] In order to make the structure more concise, the preferred movable connection structure of the valve stem 4 and the water diversion plate 5 is as follows: a valve stem through-hole 12 is formed on the water diversion plate 2, and the valve stem 4 is inserted into the valve stem through-hole 12, and is loosely matched with the valve stem through-hole 12, thereby driving the water diversion plate 2 to slide on the water outlet surface 8. In order to make the valve stem 4 and the valve stem through-hole 12 fit more accurately and move smoothly, the middle part of the valve stem through-hole 12 is retracted, and the two ends gradually expand outward from the middle to form a trumpet shape, and the valve stem 4 passes through the middle part of the valve stem through-hole 12.

[0045] Since the water outlet surface 8 is prone to wear, a fixed valve plate 13 is preferably installed on the inner wall of the valve cavity 5, and the water outlet surface 8 is located on the fixed valve plate 13, so that the fixed valve plate 13 can be made of a more wear-resistant material relative to the valve housing 1.

[0046] Preferably, to facilitate the installation of the elastic member 3, the elastic member 3 is a spring, and a spring installation cavity 18 for inserting the spring is formed on the partition 14. The elastic member 3 is limited in the installation cavity 18 to avoid failure after moving with the water distribution plate 2.

[0047] The preferred structure of the water outlet switching device when installed in a bathroom water outlet device is as follows. The bathroom water outlet device in this embodiment is specifically a shower head, but is not limited to this. The shower head includes a shower head panel 19 and a shower head handle 20. The button 11 is located on the outside of the shower head handle 20 and is located in a position that is easy for the user's thumb to operate when holding the shower head handle 20. The shower head panel 19 has multiple groups of water outlet holes, and each water outlet 7 is correspondingly connected to one group of water outlet holes.

[0048] Example 2

[0049] Key References Figure 7 、 Figure 8 As shown, the only difference between Example 2 and Example 1 is that the water outlet surface 8 is an arc surface, specifically a concave spherical surface, and the center of the concave spherical surface is preferably consistent with the center of the ball head 22. The partition 14 and the water diversion plate 2 are arranged at intervals, and preferably, the end of the valve stem 4 located in the valve housing 1 is connected to the water diversion plate 2 through a hole column and a linear sliding connection, and the straight line in the linear sliding direction passes through the center of the ball head 22, and the elastic member 3 is sleeved on the outer periphery of the valve stem 4 and swings together with the swing of the valve stem 4. Such a setting can make the process of swinging the valve stem 4 by operating the button 11 smoother.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the design of this case. Any equivalent changes made based on the key design of this case shall fall within the scope of protection of this case.
