Description

Technical Field

[0001] This utility model relates to a push-button shower head. Background Technology

[0002] Showerheads are now a necessity in our lives. To meet people's different water output requirements, modern showerheads are multifunctional, meaning they can produce various water spray effects. To achieve different water spray effects, a switching mechanism is needed. In rod-shaped showerheads, due to their circular shape, these showerheads generally use a push-button switching method. The main mechanism involves the shaft involved in the switching seal moving axially in the same direction as the water inlet. However, this structure can easily cause the shaft to be affected by direct water pressure or water pressure imbalance. The water pressure is concentrated in one direction and increases with the increase of water pressure, which will increase the force required for switching. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a push-button shower head.

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

[0005] A push-button shower head includes a housing, within which a matching inlet pipe and valve seat are disposed. An inlet is formed between the inlet pipe and the valve seat. The shower head also includes a valve core capable of axial movement within the inlet pipe and valve seat. The valve core has a water passage that communicates with the inlet. A water outlet is disposed around the periphery of the valve core, maintaining connection with the inlet. Sealing rings are disposed on the outer periphery of the valve core at both axial ends of the water outlets; one sealing ring maintains contact with the inlet pipe, and the other sealing ring maintains contact with the valve seat.

[0006] In this embodiment of the utility model, a sealing group is formed between two sealing rings located on the outer periphery of the valve core, and a vent hole is also included, which can be connected to the two sides of the sealing group.

[0007] In this embodiment of the utility model, the water inlet pipe includes an inner pipe and an outer pipe, and a water inlet channel is formed between the inner pipe and the outer pipe. The water inlet channel can be connected to the water inlet. The valve seat is inserted into the inner circumference of the outer pipe, and a sealing element is provided between the outer circumference of the valve seat and the outer pipe.

[0008] In this embodiment of the utility model, one end of the valve core is inserted into the inner tube, and the end of the valve core inserted into the inner tube is sealed. A sealing ring is provided between the outer periphery of the end of the valve core inserted into the inner tube and the inner tube. Another sealing ring is located on the outer periphery of the middle part of the valve core. A cavity is formed between one end of the valve core and the inner tube, and the cavity is connected to the vent hole.

[0009] In this embodiment of the utility model, a spring sheet is provided on the outer periphery of the water inlet pipe, and a snap-fit ​​block is provided on the spring sheet. The peripheral side wall of the housing is provided with a snap-fit ​​interface that can cooperate with the snap-fit ​​block to fix the water inlet pipe to the housing. The outer periphery of the valve seat is provided with a snap-fit ​​part, and the outer pipe side wall is provided with a snap-fit ​​opening. The snap-fit ​​part can cooperate with a buckle to fix the valve core to the water inlet pipe.

[0010] In this embodiment of the utility model, a sliding block that can cooperate with the valve core is also included. A push button is provided on the housing, and the push button can cooperate with the sliding block to enable the sliding block and the valve core to move axially synchronously within the housing. The sliding block is provided with a water outlet that can communicate with the water passage. A water outlet component is also provided inside the housing, and the water outlet component is provided with at least two axially distributed water outlet openings, and the water outlet can communicate with the water outlet openings.

[0011] In this embodiment of the present invention, a snap-fit ​​protrusion is provided on the outer periphery of the other end of the valve core, and a snap-fit ​​opening is provided on the inner periphery of the sliding block. The snap-fit ​​protrusion can engage with the snap-fit ​​opening so that the valve core can move axially synchronously with the sliding block.

[0012] In this embodiment of the utility model, the sliding block is provided with a sealing gasket at the water outlet, and the sealing gasket can be connected to the water outlet component around the water outlet opening.

[0013] In this embodiment of the utility model, the water outlet is provided with a groove, and a matching spring and a ball are provided in the groove.

[0026] 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 utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," 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 utility model according to the specific circumstances.

[0028] 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.

[0029] Referring to the accompanying drawings, a push-button shower head includes a housing 10, which can also be considered an outer shell. Inside the housing are a cooperating inlet pipe 20 and a valve seat 30. An inlet 11 is formed between the inlet pipe and the valve seat. More specifically, the inlet is located between the inner pipe and the valve seat. The shower head also includes a valve core 40 capable of axial movement (A) within the inlet pipe and valve seat. The inlet pipe and valve seat are fixed relative to the housing. The valve core has a water passage 41 that communicates with the inlet. Water flowing through the water passage flows towards the rear end and, after passing through a switching device, exits from different water outlets. It is a water stop; the valve core is provided with a water inlet 42 on its periphery, that is, the water passage is radially water-intake through the water inlet, which can be elongated because the valve core can move axially. The water inlet can maintain connection with the water inlet; a sealing ring 43 is provided on the outer periphery of the valve core at both ends of the water inlet. One sealing ring can maintain cooperation with the water inlet pipe, and the other sealing ring can maintain cooperation with the valve seat. In one embodiment, the sealing ring is an oil-based sealing ring; the side water inlet, that is, the radial water inlet, is balanced by the oil seals on both sides of the axis to avoid the influence of water pressure.

[0030] Preferably, a sealing group is formed between the two sealing rings located on the outer periphery of the valve core, and a vent hole 21 is also included. The vent hole can be connected to the two sides of the sealing group, so that the atmosphere is matched with the two sides of the two sealing rings, realizing the connection between the two oil seals and the atmosphere, balancing the water pressure, and reducing the impact of water pressure on the movement of the valve core (that is, water flow switching).

[0031] Furthermore, the water inlet pipe includes an inner pipe 22 and an outer pipe 23, forming a water inlet channel 24 between the inner and outer pipes. The water inlet channel can be connected to the water inlet. The valve seat is inserted into the inner circumference of the outer pipe, and a sealing element 31 is provided between the outer circumference of the valve seat and the outer pipe. It cooperates with two sealing rings to ensure that the water flow can only flow from the water inlet channel to the water passage without leakage. The gap between the valve seat and the water inlet pipe allows communication with the atmosphere, which cooperates with the two sides of the oily sealing ring to balance the water pressure. One end of the valve core is inserted into the inner tube. The end of the valve core inserted into the inner tube is sealed, that is, this section is blocked. In other words, the valve core allows water to enter radially and exit axially from the other end. A sealing ring is provided between the outer circumference of the end of the valve core inserted into the inner tube and the inner tube. Another sealing ring is located on the outer circumference of the middle part of the valve core and cooperates with the valve seat. A cavity 25 is formed between one end of the valve core and the inner tube. The cavity is connected to a vent hole. The size of the cavity changes with the size of one end of the valve core. However, the setting of the vent hole can ensure that the pressure in the cavity remains balanced when the valve core moves and is not affected by the movement of the valve core.

[0032] Furthermore, a spring piece 26 is provided on the outer periphery of the water inlet pipe, and a snap-fit ​​block 27 is provided on the spring piece. A snap-fit ​​interface 12 that can cooperate with the snap-fit ​​block is provided on the peripheral side wall of the housing to fix the water inlet pipe to the housing. A snap-fit ​​part 32 is provided on the outer periphery of the valve seat, and a snap-fit ​​opening 28 is provided on the side wall of the outer pipe. The snap-fit ​​part can cooperate with the snap-fit ​​to fix the valve core to the water inlet pipe, thus achieving the fixed connection of the valve seat, the water inlet pipe and the housing.

[0033] Preferably, it also includes a device for switching water flow, mainly comprising: a sliding block 50 that cooperates with the valve core; a push button 13 provided on the housing, the push button being able to cooperate with the sliding block so that the sliding block and the valve core can move axially synchronously within the housing; the sliding block being provided with a water outlet 51 that can communicate with a water passage; and a water outlet component 60 provided inside the housing, the water outlet component being provided with at least two axially distributed water outlet openings 61, the water outlet being able to communicate with the water outlet openings, each water outlet opening serving a water splash function. A locking protrusion 44 is provided on the outer periphery of the other end of the valve core, and a locking opening 53 is provided on the inner periphery of the sliding block, the locking protrusion being able to engage with the locking opening so that the valve core and the sliding block can move axially synchronously. By pushing the push button, the sliding block is driven to move axially, and the sliding block moves in conjunction with the valve core. The sliding block is equipped with a sealing gasket 63 at the water outlet. The sealing gasket can be connected to the water outlet component around the water outlet. The sealing gasket can adopt the structure of a cat's eye gasket to achieve end face sealing, ensure the overall structure is airtight, and prevent water leakage.

[0034] Furthermore, the water outlet component is provided with a groove 64, and a matching spring 71 and a ball bearing 72 are disposed within the groove. The sliding block is provided with axially distributed stop grooves 52, the number of which can be adapted to the number of water outlet openings. When the ball bearing is inserted into a stop groove, the water outlet can be adapted to and connected with a water outlet opening, that is, to complete one switching of water flow. A sealing ring 65 is also provided between the other end of the valve core and the sliding block.
