Description

Technical Field

[0001] The utility model relates to the technical field of water outlet switching devices, and particularly relates to a push-button type water outlet switching device. Background Art

[0002] There are the following two common water outlet switching designs on water outlet switching devices; one is to set a button, and by pressing the button multiple times, the water outlet switching device can be cycled among multiple water outlet gears. In this design, usually, the user cannot switch to the water outlet gear they want with one key; the other is to set multiple buttons, and pressing the corresponding button will switch to the corresponding water outlet gear. In this design, although it can achieve switching to the desired water outlet gear with one key, the user needs to press different buttons at multiple places, and the operation is not convenient enough. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a push-button type water outlet switching device, and the technical problem to be solved is how to achieve one-key switching among multiple water outlet gears only by operating one button.

[0004] To achieve the above purpose, the solution of the utility model is: a push-button type water outlet switching device, including a valve housing, a water distribution plate, a button, and a push rod;

[0005] A valve cavity is formed inside the valve housing. There is a water inlet and at least one water outlet that leads to the outside of the valve housing in the valve cavity. A water outlet plane is formed on the inner wall of the valve cavity, and all the water outlets are located on the water outlet plane;

[0006] The bottom surface of the water distribution plate is attached to the water outlet plane. The water distribution plate is penetrated up and down with water distribution ports. The water flow entering the valve cavity from the water inlet is on the side where the top surface of the water distribution plate is located. The middle of the top surface of the water distribution plate is high and the surrounding is low;

[0007] The button is located outside the valve housing and on the side of the water distribution plate facing away from the water outlet plane. The button is in a disc shape and is ball-jointed to the valve housing in the middle;

[0008] A plurality of push rods are provided. The plurality of push rods are distributed around the position where the button is ball-jointed to the valve housing. Each push rod respectively slides into the valve cavity, the top ends respectively abut against the bottom surface of the button, and the bottom ends respectively abut against the top surface of the water distribution plate, and respectively form a wedge fit with different positions on the top surface of the water distribution plate;

[0009] So that when the button swings around the ball-joint, it can drive each push rod to insert or retract into the valve cavity, and the inserted push rod can push the water distribution plate to translate and slide along the water outlet plane, align the water distribution ports with different positions on the water outlet plane, and further enable the water distribution ports to be docked or misaligned with at least one water outlet.

[0010] Further, a cage is fixedly arranged in the valve cavity. The cage is attached to the side of the water distribution plate facing away from the water outlet plane, and the water distribution plate translates and slides between the cage and the water outlet plane.

[0011] Further, a longitudinally extending limiting groove is arranged on the cage, and a limiting portion protrudes from the side wall of the push rod. The limiting portion is held in the limiting groove to limit the rotation of the push rod around its own axis.

[0012] Further, a sealing ring is clamped between the cage and the top surface of the valve cavity, and one sealing ring is provided corresponding to each push rod. Each push rod penetrates into a sealing ring with interference fit for water sealing.

[0013] Further, the water distribution plate is located between the push rods, and its top surface is conical. An inclined wedge surface matching the inclined direction of the corresponding position on the top surface of the water distribution plate is arranged at the bottom side of each push rod.

[0014] Further, an elastic member is also arranged in the valve cavity. The elastic member elastically pushes against the water distribution plate towards the direction of the water outlet plane.

[0015] Further, the top end of the push rod is hemispherical.

[0016] Further, four push rods are provided. The four push rods are evenly distributed around the position where the button is ball-jointed to the valve housing.

[0017] Further, a plurality of water outlet ports are arranged on the water distribution plate. The plurality of water outlet ports are arranged in a surrounding manner. When the button swings to be parallel to the water distribution plate, the water distribution ports are aligned with the center of the arrangement positions of the water outlet ports.

[0018] Further, when the water distribution plate translates and slides on the water outlet plane, it can slide to make the water distribution ports misaligned with all the water outlet ports at the same time, or dock with at least one water outlet port;

[0019] Or, when the water distribution plate translates and slides on the water outlet plane, the water distribution ports are only used to switch and dock with different water outlet ports.

[0020] After adopting the above scheme, the beneficial effect of the utility model is that since the button is ball-hinged on the valve housing, and multiple push rods are distributed around the position of the button ball-hinged on the valve housing, and each push rod slides into the valve cavity respectively, and the top end rests on the bottom surface of the button respectively. Therefore, when the button is pressed to make the button swing to one direction, the button will push down the push rod in that direction, so that these push rods are inserted into the valve cavity. Since the bottom end of each push rod forms an oblique wedge fit with the top surface of the water diversion plate which is high in the middle and low around, these push rods will push the water diversion plate to slide in the corresponding direction on the horizontal plane, so that the water diversion port on the water diversion plate is aligned with the water outlet at the corresponding position on the horizontal plane, so that the water outlet discharges water, or the water outlet at the corresponding position is staggered to stop the water outlet from discharging water. When multiple water outlets are set, the water diversion port can be aligned with the water outlet at different positions by pressing the button in different directions, so that one-key switching between multiple water outlet gears can be completed by operating only one button.

DETAILED DESCRIPTION

[0028] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the claims, description and the above-mentioned drawings of the present utility model, unless otherwise clearly defined, for orientation terms, such as the use of terms "center", "lateral", "longitudinal", "horizontal", "vertical", "top", "bottom", "inner", "outer", "upper", "lower", "front", "rear", "left", "right", "clockwise", "counterclockwise", etc. to indicate the orientation or position relationship is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it should not be construed as limiting the specific protection scope of the present utility model.

[0030] The present utility model provides a push-button type water outlet switching device, as Figure 1-6 shown, for being installed on the handle 16 of a hand-held water outlet device to perform water outlet switching on the hand-held water outlet device (the so-called water outlet switching means enabling different water outlet holes to discharge water), and of course, it can also be used on other water outlet devices, not limited thereto. The rocker button water outlet switching device specifically includes a valve housing 1, a water distribution plate 2, a button 3 and a push rod 4. Specifically, in this embodiment, the valve housing 1 is arranged inside the handle 16;

[0031] A valve cavity 5 is formed inside the valve housing 1. The valve cavity 5 has a water inlet 6 leading to the outside of the valve housing 1 and at least one water outlet 7. The valve cavity 5 intakes water through the water inlet 6 and discharges water through the water outlet 7. A water outlet plane 8 is formed on the inner wall of the valve cavity 5, and the water outlets 7 are all located on the water outlet plane 8;

[0032] The bottom surface of the water distribution plate 2 is attached to the water outlet plane 8 to form a water seal with the water outlet plane 8 (the so-called water seal means that water flow cannot enter between the water distribution plate 2 and the water outlet plane 8). The water distribution plate 2 is vertically penetrated with a water distribution port 9. The setting position of the water distribution port 9 only needs to satisfy that the water flow entering the valve cavity 5 from the water inlet 6 flows into the side where the top surface of the water distribution plate 2 is located (i.e., the side of the water distribution plate 2 facing away from the water outlet plane 8). The middle of the top surface of the water distribution plate 2 is high and the periphery is low, preferably in a conical shape;

[0033] The button 3 is located outside the valve housing 1 and in this embodiment, it also protrudes outside the handle 16 for the thumb of the user to press when holding the handle 16. The button 3 is located on the side of the water distribution plate 2 facing away from the water outlet plane 8. The button 3 is in a disc shape and is ball-jointed to the valve housing 1 in the middle, and the so-called ball joint forms a ball hinge structure;

[0034] There are multiple push rods 4, and the multiple push rods 4 are distributed around the position of the key 3 ball-jointed to the valve housing 1. Each push rod 4 slides into the valve cavity 5 respectively, and the tops respectively abut against the bottom surface of the key 3. To make the movement smoother, it is preferred that the top of the push rod 4 is hemispherical. The water distribution plate 2 is located between the push rods 2. The bottoms of the push rods 4 respectively abut against different positions around the top surface of the water distribution plate 2. An inclined wedge surface 14 matching the inclined direction of the corresponding position on the top surface of the water distribution plate 2 is provided on the bottom side of each push rod 4 to form an inclined wedge fit with different positions on the top surface of the water distribution plate 2 respectively;

[0035] Furthermore, when pressing the key 3 in one direction, when the key 3 swings around the ball-joint, it can drive the push rod 4 in this direction to be inserted into the valve cavity 5, so that the inserted push rod 4 pushes the water distribution plate 2 to translate and slide along the water outlet plane 8. When the water distribution plate 2 slides horizontally, it pushes the other push rods 4 to retract from the valve cavity 5 to make way. By translating and sliding the water distribution plate 2, the water outlet 9 can be aligned with different positions on the water outlet plane 8, and then the water outlet 9 can be docked or misaligned with at least one water outlet 7.

[0036] Specifically, the setting of the water outlet 7 can be the following two more specific implementation manners: Implementation manner one, when the water distribution plate 2 translates and slides on the water outlet plane 8, it can slide to make the water outlet 9 misaligned with each water outlet 7 at the same time to stop water, or dock with at least one water outlet 7 to open the water outlet. In the scheme where there are multiple water outlets 7, the water outlet can also be switched by docking with different water outlets 7; Implementation manner two, when the water distribution plate 2 translates and slides on the water outlet plane 8, the water outlet 9 is only used to switch and dock different water outlets 7 and is only used for water outlet switching. In the embodiment with multiple water outlets 7, the water outlet 9 can be designed to be able to align with multiple water outlets 7 at the same time.

[0037] To improve the stability during use, it is preferred that a cage 10 is fixedly arranged in the valve cavity 5. The cage 10 is attached to the side of the water distribution plate 2 facing away from the water outlet plane 8. The cage is provided with a hollow structure and does not affect the water flow. The water distribution plate 2 translates and slides between the cage 10 and the water outlet plane 8. Furthermore, the cage 10 can limit the water distribution plate 2 from flipping and tilting; In order to keep the inclined wedge surfaces 14 on the bottom sides of the push rods 4 always match the inclined direction of the corresponding positions on the top surface of the water distribution plate 2, a longitudinally extending limiting groove 11 is provided on the cage 10, and a limiting portion 12 protrudes from the side wall of the push rod 4. The limiting portion 12 is kept in the limiting groove 11 to limit the push rod 4 from rotating around its own axis; To achieve the water seal between the push rod 4 and the valve housing 1, a sealing ring 13 is clamped between the cage 10 and the top surface of the valve cavity 5, and one sealing ring 13 is provided corresponding to each push rod 4. Each push rod 4 passes through one sealing ring 13 with an interference fit to perform the water seal.

[0038] An elastic member 15 is further disposed in the valve cavity 5. The elastic member 15 elastically pushes against the water distribution plate 2 towards the direction of the water outlet plane 8. The water flow entering the valve cavity 5 from the water inlet 6 is located on the side of the water distribution plate 2 facing away from the water outlet plane 8. The water pressure acts on the side of the water distribution plate 2 facing away from the water outlet plane 8, pressing the water distribution plate 2 against the water outlet plane 8. The greater the water pressure, the greater the pressure, which helps to form a water seal between the water distribution plate 2 and the water outlet plane 8. The elastic member 15 elastically pushes against the water distribution plate 2 towards the direction of the water outlet plane 8, so that when the water pressure in the valve cavity 1 is relatively low, the water distribution plate 2 can be pressed against the water outlet plane by the elastic member 15, and a water seal can still be formed. The elastic member is preferably a spring sandwiched between the water distribution plate 2 and the cage 10 and is limited on the water distribution plate 2 and moves translationally with the water distribution plate 2.

[0039] Specifically, in this embodiment, four push rods 4 are provided. The four push rods 4 are evenly distributed around the position where the button 3 is spherical-jointed to the valve housing 1. Four water outlets 7 are also provided. The four water outlets 7 are arranged in a circular pattern and correspond to the directions of the four push rods 4 respectively. Of course, the number of water outlets 7 can also be set in other ways. When the button 3 swings to be parallel to the water distribution plate 2, the water distribution ports 9 are aligned with the centers of the positions where the water outlets 7 are arranged.

[0040] Preferably, a fixed valve plate 17 is disposed in the valve cavity 5. The water outlet plane 8 is formed on the fixed valve plate 17. The fixed valve plate can be made of a material more wear-resistant than the valve housing 1 to improve the durability during use.

[0041] The above are only the preferred embodiments of the present invention and do not limit the design of this case. All equivalent changes made according to the key design of this case fall within the protection scope of this case.
