Description

A push-to-switch shower head Technical Field

[0001] This utility model relates to the field of bathroom product technology, and more specifically, to a push-switch shower head. Background Technology

[0002] Most push-button switch showerheads on the market are designed with a push button connected to a lever, which drives the switching mechanism to rotate the water distribution plate, thus switching the water spray pattern. The switching mechanism, typically located on the back of the water outlet component, is a ratchet mechanism, linkage mechanism, or worm gear mechanism. Because existing switching mechanisms are bulky and require significant structural space, it's difficult to add other functional structures to the water outlet component to maintain the overall size of the showerhead, resulting in relatively limited functionality for existing push-button switch showerheads. Summary of the Invention

[0003] This utility model discloses a push-to-switch shower head, which aims to improve the problem of the large size of existing switching mechanisms.

[0004] The present invention adopts the following solution:

[0005] A push-to-switch shower head includes a body having a water inlet channel, a water distribution chamber, and at least two water outlet channels. A water distribution plate is disposed in the water distribution chamber. The water distribution plate is configured to be driven by a switching element to control the water inlet channel to switchly connect or disconnect with each water outlet channel. The switching element includes a gear and a rack. By operably pushing a push button exposed on the body, the rack is moved in conjunction with the push button, which in turn causes the gear meshing with the rack to drive the water distribution plate, which is coaxially arranged with the rack, to rotate.

[0006] As a further improvement, an installation cavity is provided between the water distribution cavity and the water inlet channel, and a control valve for controlling the opening and closing of the water inlet channel and the water distribution cavity is installed in the installation cavity.

[0007] As a further improvement, the mounting cavity is located at the end of the water inlet channel and is provided on the extension line of the handle.

[0008] As a further improvement, the control valve is connected to a switch exposed on the back of the body, and the opening and closing of the control valve is controlled by pressing the switch.

[0009] As a further improvement, the water distribution chamber is located on one side of the mounting chamber, the water inlet of the water distribution chamber is connected to the water outlet of the mounting chamber, and the water outlet of the water distribution chamber is provided with multiple water outlets, each water outlet channel being configured to correspond and connect with a water outlet.

[0010] As a further improvement, the water distribution plate is provided with a water distribution port. When the water distribution port is aligned and connected with the water outlet, the water flow can enter the water outlet channel from the water distribution port.

[0011] As a further improvement, the rack is arranged along the extension direction of the handle and is at least partially installed inside the handle.

[0012] As a further improvement, the push button is located on the front of the handle and connected to a movable part fitted on the inner water inlet tube. Pushing the push button causes the movable part to move the rack.

[0013] As a further improvement, the movable part is provided with a socket, and the push button is provided with a buckle for engaging with the socket.

[0014] As a further improvement, a hook is provided on one side of the moving part, and a locking part is provided on the rack for connecting with the hook.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] 1. The switching mechanism is designed as a gear and rack mechanism, which reduces the need for connecting rods, ratchet wheels, rocker arms, and other structures. It directly converts linear motion into the circular motion of the water distribution plate, resulting in a simple structure and small size. This reduces the internal space occupied by the switching mechanism, allowing for the addition of other functional structures to the main body, thus enriching the shower head's functionality and enhancing its market competitiveness. Furthermore, the gear and rack transmission is smooth, enabling stepless adjustment, and the rack length can be selected according to water distribution needs, ensuring high compatibility.

[0017] 2. The rack is arranged along the extension direction of the handle and is at least partially installed inside the handle to further reduce the structural space occupied by the switching components, making the arrangement of other functional structures more convenient.

[0018] 3. An installation cavity is provided between the water distribution chamber and the water inlet channel. By controlling the control valve in the installation cavity, the water flow of the shower head can be paused, i.e., it is in a dripping state. This avoids water temperature changes caused by turning the faucet on and off, or makes it convenient to control the water flow when holding the shower head without having to operate it at the faucet end, thus improving the user experience.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Examples

[0033] Referring to Figures 1 to 11, this embodiment provides a push-to-switch shower head, including a body 1. The body 1 has a water inlet channel 11, a water distribution chamber 12, and at least two water outlet channels 13. A water distribution plate 2 is disposed in the water distribution chamber 12. The water distribution plate 2 is configured to be driven by a switching element 3 to control the water inlet channel 11 to switch between being connected to or disconnected from each water outlet channel 13. The switching element 3 includes a gear 31 and a rack 32. By pushing the push button 4 exposed on the body 1 in an operable manner, the rack 32 is moved in conjunction with the push button 4, which in turn causes the gear 31 meshing with the rack 32 to drive the water distribution plate 2, which is coaxially arranged with the rack 32, to rotate.

[0034] It should be noted that in this embodiment, the switching component 3 is set as a gear and rack mechanism, which can reduce the need for connecting rods, ratchet, rocker arms, and other structures, directly converting linear motion into the circular motion of the water distribution plate 2. This results in a simple structure and small size, thereby reducing the internal space occupied by the switching component 3 on the main body 1. This allows for the addition of other functional structures to the main body 1, enriching the shower head's functions and enhancing its market competitiveness. Furthermore, the gear 31 and rack 32 provide smooth transmission, enabling stepless adjustment. The length of the rack 32 can also be selected according to the water distribution needs, offering high compatibility.

[0035] In a preferred embodiment, the rack 32 is arranged along the extension direction of the handle 14 and is at least partially installed inside the handle 14, thereby further reducing the structural space occupied by the switching element 3 and making the arrangement of other functional structures more convenient. For example, the handle 14 is provided with a water inlet inner tube 141, the water inlet channel 11 is provided in the water inlet inner tube 141, the push button 4 is arranged on the front of the handle 14 and connected to the moving element 5 sleeved on the water inlet inner tube 141, and the moving element 5 drives the rack 32 to move by pushing the push button 4.

[0036] In one embodiment, the movable member 5 is provided with a guide groove, and the inner water inlet pipe 141 is provided with a guide rail. The guide groove cooperates with the guide rail to enable the movable member 5 to move linearly along the guide rail. Specifically, the movable member 5 is provided with a socket 51, and the push button 4 is provided with a buckle 41 for engaging with the socket 51. A hook portion 52 is provided on one side of the movable member 5, and a locking portion 321 for connecting with the hook portion 52 is provided on the rack 32.

Further, the control valve 6 is connected to a switch 7 exposed on the back of the main body 1, and the opening and closing of the control valve 6 is controlled by pressing the switch 7. In one embodiment, controlling the opening and closing of the control valve 6 realizes the function of pausing the water flow of the shower head, i.e., keeping it in a dripping state, thereby avoiding changes in water temperature caused by turning the faucet on and off, or facilitating water flow control when holding the shower head without needing to operate it at the faucet end, thus improving the user experience. The switch 7 and the push button 4 are located on different sides to avoid user misoperation. The control valve 6 can be a switch valve, the structure and principle of which are existing technologies and will not be described in detail here.

[0038] In another embodiment, the mounting cavity 15 is located at the end of the water inlet channel 11 and is positioned on the extension line of the handle 14 to make the structure more compact. The water distribution cavity 12 is located on one side of the mounting cavity 15, and the water inlet end of the water distribution cavity 12 is connected to the water outlet end of the mounting cavity 15. The water outlet end of the water distribution cavity 12 is provided with multiple water outlets, and each water outlet channel 13 is configured to correspond and communicate with each water outlet. The water distribution plate 2 is provided with a water distribution port 21. When the water distribution port 21 is aligned and connected with the water outlet, water can flow from the water distribution port 21 into the water outlet channel 13. For example, the main body 1 is provided with three water outlet channels 13, the water outlet end of the water distribution cavity 12 is provided with six water outlets, two water outlets are symmetrically arranged and communicate with the same water outlet channel 13, and two water distribution ports 21 are symmetrically arranged on the water distribution plate 2 to ensure the water flow rate. Preferably, at least one water outlet channel 13 is configured to communicate with the spray gun nozzle 16 on the side of the body 1, so that the shower head has a spray gun function for user convenience.
