Description

Technical Field

[0001] This invention relates to a single-button shower head with a pause function for water flow. Background Technology

[0002] Most single-button multi-functional showerheads on the market do not have a pause function (pause function does not mean no water flow, but rather a low water flow rate, such as <0.5 gpm / min). Showerheads with a pause function have separate water distribution and pause functions, requiring two separate locations for purging. This results in a larger overall size and more complex structure. Furthermore, when switching to the pause function, the water flow direction and the switching indicator cause the required force to be too high, leading to an imbalance in the force required during the entire replacement process. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a single-button shower head with a pause water function.

[0004] This invention is achieved through the following technical solution:

[0005] A single-button shower head with a pause function includes a water outlet body with a central cavity. The water outlet body is provided with a water outlet and a water channel that can communicate with the cavity. The water outlet and water channel are distributed on the outer periphery of the water outlet body. It also includes an upper cavity that can communicate with the cavity body. The upper cavity is provided with a rotatable water distribution plate. The lower end of the water distribution plate can be connected to the upper end of the cavity body. The water distribution plate is provided with a baffle that can block the water outlet end of the water channel.

A first mating surface is provided on one side of the first protrusion, and a second mating surface is provided on one side of the second protrusion. The first mating surface and the second mating surface cooperate to enable the gear to drive the ratchet to rotate synchronously.

[0012] In this embodiment of the invention, a latch is also provided on the rotating shaft. The latch restricts the gear and ratchet on the rotating shaft. The ratchet is located above the gear.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] Referring to the accompanying drawings, a single-button showerhead with a pause function includes a water outlet body 10 with a central cavity 11. The water outlet body has a water outlet 12 and a water channel 13 that communicates with the cavity. The water outlet and water channel are distributed on the outer periphery of the water outlet body, forming a ring around the outer periphery of the cavity. This arrangement makes the overall layout of the water outlet body more compact, providing a basis for a smaller showerhead design. It also includes an upper cavity 14 that communicates with the cavity. The upper cavity has a rotatable water distribution plate 20. The lower end of the water distribution plate can be fitted and connected to the upper end of the cavity, forming a sealed fit. The water distribution plate has a feature that can block... The baffle 21 of the water outlet 19 (or the inlet connecting the water channel to the cavity) is in a state of water suspension when it is engaged with the water outlet. The middle of the water distribution plate is provided with a channel 22 that connects the cavity and the upper cavity. Because the water flows horizontally into the cavity from the water channel, and the water distribution plate and the outlet are sealed together, the water can only flow upward from the cavity, through the channel from the lower end of the water distribution plate to the upper end of the water distribution plate, that is, into the upper cavity. The water distribution plate located next to the channel is provided with a water outlet 23 that connects to the outlet, and then flows to the outlet through the water outlet. Multiple outlets can be provided, and each outlet corresponds to the water path 15 of the corresponding water spray. Water flows downward from the outlet and then flows out horizontally. In one embodiment, the inlet water flow and the outlet water flow can occur on the same horizontal plane, which can effectively reduce the thickness of the shower head and make it more compact. The text is mainly described with the downward water flow direction as the reference direction.

[0032] Preferably, the upper surface of the water outlet body is provided with at least two water outlets. The specific number of water outlets and water channels depends on the amount of functional water required by the specific shower head. Each water outlet corresponds to a water channel 15 with different water spray patterns in the water outlet body. The water outlets, water channels, and water passages are distributed in a ring on the outer periphery of the cavity, making the whole more compact. The water outlets and the upper opening of the cavity are provided with sealing rings 90 that can seal with the lower end face of the water distribution plate to ensure that there is no leakage. The water flow in the cavity can only flow to the water channel in sequence through the channel, the water inlet, and the water outlet.

[0033] In use, the water outlet of the water channel can flow laterally into the cavity, and the baffle can be inserted vertically into the cavity and rotate synchronously with the water distribution plate within the cavity. The channel is located on the inner circumference of the baffle. Because the water channel and the baffle are laterally matched, the force on the water distribution plate and the baffle during rotation is a tangential force, so the water flow will not exert excessive force on the water distribution plate, thus avoiding a strong feeling of force during switching. The lower end of the cavity is also provided with an annular groove 16, and the lower end of the baffle can be inserted into the annular groove. The side wall of the annular groove can abut against the baffle, which can prevent the baffle from deforming under water pressure and can also reduce the thickness of the baffle, thus providing a basis for a more compact design for the entire shower head product.

[0034] Preferably, it also includes a water inlet body 30, which can be connected to a water outlet body, and an upper cavity 14 can be formed between the water inlet body and the water outlet body. The water distribution plate is set in the upper cavity body and can be sealed with the water outlet body. For details, refer to the position of the sealing ring. A water inlet channel 31 is provided in the water inlet body, which can be connected to a water channel, so that the water flow in the water inlet channel is guided to the water outlet body.

[0035] Furthermore, the lower end of the water distribution plate is provided with a baffle that can be inserted into the cavity, and the upper end of the water distribution plate is provided with a rotating shaft 24. An opening is provided on the water inlet at the upper cavity to allow one end of the rotating shaft to extend. Similarly, the opening and the rotating shaft are sealed. The rotating shaft can rotate synchronously with the water distribution plate. Preferably, the rotating shaft, the water distribution plate, and the channel are coaxially arranged. A transverse flow channel 25 is provided between the rotating shaft and the water distribution plate, so that the water in the cavity can flow into the upper cavity. The flow channel can be connected to the vertically arranged channel. One end of the rotating shaft can extend out of the upper cavity and connect to the drive mechanism. The drive mechanism can drive the rotating shaft to rotate.

[0036] The driving mechanism is described below. It includes a ratchet 50 and a gear 40 that cooperate with each other. The ratchet and the rotating shaft can be connected by a key and keyway. The ratchet is sleeved on the outer circumference of the rotating shaft and can rotate synchronously with it. Similarly, the gear is also sleeved on the outer circumference of the rotating shaft. At first, the gear rotates the water inlet body. The rotation of the gear can indirectly drive the rotating shaft to rotate. When the gear rotates in the reverse direction, it cannot drive the rotating shaft to rotate in the reverse direction as well. The gear has a first protrusion 41 arranged in a ring on one end face facing the ratchet, and the ratchet has a second protrusion 51 arranged in a ring on one end face facing the gear. A first mating surface 42 is provided on one side of the first protrusion, and a second mating surface 52 is provided on one side of the second protrusion. The first mating surface and the second mating surface cooperate to enable the gear to drive the ratchet to rotate synchronously. Through the abutting cooperation of the first mating surface and the second mating surface, the gear can drive the ratchet to rotate. This can be said to be a forward rotation.

[0037] When the gear rotates in the reverse direction, a latch 70 is also provided on the rotating shaft. The latch restricts the gear and ratchet on the rotating shaft. The ratchet is located above the gear. A spring 71 is also provided between the ratchet and the latch. The ratchet can also move axially along the rotating shaft, thus ensuring that the spring always exerts a force on the ratchet to move axially toward the gear. Although the ratchet and the gear will move and separate axially relative to each other, a first inclined surface 43 is provided on the other side of the first protrusion, and a second inclined surface 53 is provided on the other side of the second protrusion. The first inclined surface and the second inclined surface are matched. The gear rotates, while the ratchet moves axially but does not rotate. When the gear reverses, the ratchet moves axially between the first and second inclined surfaces because the gear does not move axially relative to the rotating shaft. This causes the ratchet to move axially and separate from the gear, compressing the spring. In this state, the ratchet, rotating shaft, water distribution plate, and baffle do not rotate until the gear reverses completely. At this point, the ratchet moves axially toward the gear under the action of the spring, thus pre-fitting the first and second mating surfaces, facilitating the next rotation of the ratchet rotating shaft, water distribution plate, and baffle by the gear.

[0038] More specifically: the drive mechanism also includes a moving block 60, on which a rack 61 is provided to drive the gear to rotate. A return spring 62 is also provided between the moving block and the water inlet body. The return spring enables the rack to reciprocate, that is, the rack advances a certain distance, driving the gear, ratchet, and rotating shaft to rotate. Then, under the action of the return spring, the gear reverses, and the gear and the moving block return to the initial position. In this way, the moving block can be consistently driven to move the ratchet and rotating shaft to rotate in one direction. It also includes an elastic plate 63, one end of which is connected to the water inlet body, and the other end of which can cooperate with the ratchet teeth 54 of the ratchet to prevent the ratchet from rotating in the opposite direction.

[0039] Furthermore, it also includes a connector 81, the middle of which is hinged to the water inlet body. One end of the connector is connected to the moving block, and the other end is connected to the button 82. Pressing the button can drive the connector to rotate, thereby moving the moving block, and finally causing the ratchet, rotating shaft, water distribution plate, and baffle to rotate a certain angle. After releasing the button, under the action of the return spring, the moving block, connector, and button are reset, and the ratchet (axial movement), rotating shaft, water distribution plate, and baffle do not rotate. Pressing the button again causes the ratchet, rotating shaft, water distribution plate, and baffle to rotate a certain angle again, thus switching the function.

[0040] More specifically, this invention requires a sealed connection between the inlet and outlet water bodies. First, water flows through the inlet channel of the inlet water body into the cavity connected to the outlet water body. Then, it flows into the upper cavity formed by the connection of the outlet and inlet water bodies. A water distribution plate is designed between the cavity and the upper cavity. The center of the water distribution plate is hollow, forming a channel, allowing water to flow through the channel in the hollow part of the water distribution plate into the upper cavity. Additionally, a baffle is located below the water distribution plate. When the baffle rotates to the water inlet end of the water channel, the side of the baffle is pressed tightly against the side of the water inlet end, almost completely blocking the water flow. Only a small amount of water flows into the upper cavity through the gap between the inner peripheral wall of the cavity and the outer peripheral wall of the baffle. Simultaneously, the side wall of the annular groove supports the baffle, preventing deformation and retraction caused by the impact of the inlet water pressure, which would enlarge the gap between the inner peripheral wall of the cavity and the outer peripheral wall of the baffle, thus increasing the water flow. Because it is a side seal, the force on the water distribution plate during rotation is a tangential force, so it does not cause a significant force sensation. Next, the water distributor has inlets connecting different water flow paths, and the water distributor and the water outlet are sealed by a specially shaped sealing ring. When a finger presses the button, the button pushes the moving part and rack forward through the connecting part that acts as an intermediate transmission. The rack drives the drive gear to rotate, and the first protrusion on the upper end of the drive gear pushes the second protrusion on the lower end of the ratchet that cooperates with it to rotate, which simultaneously drives the water distributor plate that cooperates with the ratchet to rotate. The rotation of the water distributor plate switches between different water outlet functions and creates a pause in water flow. Under the compression force of the cylindrical spring 26, the bottom surface of the water distributor plate is tightly sealed with the specially shaped sealing ring. Since a return spring is installed between the moving block, the rack and the water inlet, when the button is pressed, the return spring is compressed. When the button is released, the return spring is released under the action of the restoring force, pushing the rack to move backward, and then pushing the button back to its original position through the intermediate connecting part. During the return movement, the rack drives the drive gear to rotate, while the ratchet does not rotate. Preferably, one end of the button is hinged to the water inlet.
