Description

Technical Field

[0001] This utility model relates to kitchen and bathroom products, and more particularly to water outlet devices. Background Technology

[0002] Existing pull-out faucets typically have multiple internal water channels, with various outlet holes on the outlet cover corresponding to each channel, each outlet producing a different type of water spray. The water channels are switched by operating a valve core, thereby changing the water spray pattern.

[0003] For example, Chinese patent CN210196557U discloses a multi-functional pull-out shower head, including a switching component and an inlet component and an outlet component connected to the inlet / outlet ends of the switching component. The switching component includes a switching component body, a first switching component, a second switching component, and a first button. Both the first and second switching components are connected to the first button. The switching component body has a first water passage chamber and a second water passage chamber. Each of the first and second water passage chambers has one inlet and two outlets. The first switching component controls the opening and closing of the two outlets of the first water passage chamber, and the second switching component controls the opening and closing of the two outlets of the second water passage chamber. The inlet component is used to control the water inflow of the switching component. This utility model controls the first and second switching components by setting the first button, thereby controlling the water outlet state of the first and second water passage chambers.

[0004] However, in existing technologies, the water spray from pull-out faucets is generally a switch between jet water, shower water, aerated water, or sheet water, which does not have a dynamic water spray effect, cannot achieve wide coverage, and cannot meet the needs of users.

[0032] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0033] refer to Figures 1-14 This embodiment provides a pull-out faucet, including a fixed base 1, a pull-out tube 2, and a water outlet device 3 disposed at the end of the pull-out tube 2. The water outlet device 3 has three water outlet modes: shower water outlet, oscillating water outlet, and aerobic water outlet, to enrich the water outlet patterns of the pull-out faucet.

[0034] Therefore, the water outlet device 3 includes a housing 31, a switching component placed inside the housing 31, and a water outlet module composed of a shower water outlet component 32, an oscillating water outlet component 33, and an aerosol water outlet component 34; the switching component is used to switch the water outlet of the shower water outlet component 32, the oscillating water outlet component 33, or the aerosol water outlet component 34.

[0035] Specifically, the housing 31 is provided with a first water inlet channel 311, a second water inlet channel 312, and a third water inlet channel 313. The switching assembly includes a first switching element 35 and a second switching element 36. The first switching element 35 is used to open or close the connection between the first water inlet channel 311 and the pull-out pipe 2. When the connection between the first water inlet channel 311 and the pull-out pipe 2 is closed, the second water inlet channel 312 and the third water inlet channel 313 are connected to the pull-out pipe 2. The second switching element 36 is located at the connection between the second water inlet channel 312 and the third water inlet channel 313 and the pull-out pipe 2. When the second switching element 36 is in the initial position, the third water inlet channel 313 is open. When the user operates the second switching element 36, the third water inlet channel 313 is closed and the second water inlet channel 312 is opened. Correspondingly, the first water inlet channel 311 is connected to the oscillating water outlet component 33 to achieve oscillating water outlet, the second water inlet channel 312 is connected to the shower head water outlet component 32 to achieve aerated water outlet, and the third water inlet channel 313 is connected to the aerated water outlet component 34 to achieve aerated water outlet.

[0036] The first switching component 35 includes a button 351, a first water distribution body 352, and a first switching shaft 353. The first water distribution body 352 has a first water passage hole 3521 communicating with the first water inlet channel 311, the second water inlet channel 312, and the third water inlet channel 313. The first switching shaft 353 is disposed inside the first water distribution body 352, and a first sealing gasket 3531 is provided on the first switching shaft 353. The first switching shaft 353 is movably connected to the inner wall of the outer casing 31 through a first reset member 354, which is a spring. The button 351 is in a transmission engagement with the first switching shaft 353. When the button 351 is not pressed, the first switching shaft 353 is in its initial position. At this time, the first sealing gasket 3531 closes the connection between the first water passage hole 3521 and the first water inlet channel 311, and opens the connection between the first water passage hole 3521 and the second water inlet channel 312 and the third water inlet channel 313. When button 351 is pressed, the first switching shaft 353 moves to the second position. At this time, the first sealing gasket 3531 opens the connection between the first water passage 3521 and the first water inlet channel 311, and closes the connection between the first water passage 3521 and the second water inlet channel 312 and the third water inlet channel 313. Therefore, by simply pressing button 351, the water output of the oscillating water outlet assembly 33 can be switched.

[0037] The second switching component 36 includes a button 361, a second water distribution body 362, and a second switching shaft 363. The second water distribution body 362 has a second water passage hole 3621 communicating with the second water inlet channel 312 and the third water inlet channel 313. The second switching shaft 363 is disposed inside the second water distribution body 362, and a second sealing gasket 3631 is provided on the second switching shaft 363. The second switching shaft 363 is movably connected to the inner wall of the outer casing 31 through a second reset member 364, which is a spring. The button 361 is in a transmission engagement with the second switching shaft 363. When the button 361 is not pressed, the second switching shaft 363 is in its initial position. At this time, the second sealing gasket 3631 opens the connection between the second water passage hole 3621 and the second water inlet channel 312, and closes the connection between the second water passage hole 3621 and the third water inlet channel 313. When button 361 is pressed, the second switching shaft 363 moves to the second position. At this time, the second sealing gasket 3631 opens the connection between the second water passage 3621 and the first water inlet channel 311, and closes the connection between the second water passage 3621 and the second water inlet channel 312 and the third water inlet channel 313. Therefore, pressing button 361 can switch the water output of the shower head water outlet assembly 32. When neither button 351 nor button 361 is pressed, the aerosol water outlet assembly 34 can output water. When the first switching shaft 353 is moved to the second position by pressing button 351, the first reset member 354 is compressed and accumulates elastic reset force. When the user releases button 351, the elastic reset force can drive button 351 to reset and move back to the initial position. When the second switching shaft 363 is moved to the second position by pressing button 361, the second reset member 364 is compressed and accumulates elastic reset force. When the user releases button 361, the water pressure force F1 and the elastic reset force F2 of the second reset member 364 act on the second sealing gasket 3631 respectively. The magnitudes of the forces are the same and the directions are opposite, maintaining balance in this state. When the faucet handle turns off the water or button 351 is pressed to switch to the swing water outlet component 33, the water flow in front of the second sealing gasket 3631 stops, and the water pressure acting on the second sealing gasket 3631 is lost. At this time, the second reset member 364 can drive button 361 to reset to the initial position.

[0038] In this embodiment, the shower head water outlet assembly 32, the aerator water outlet assembly 34, and the oscillating water outlet assembly 33 are arranged concentrically from the outside to the inside along the radial direction. The shower head water outlet assembly 32 and the aerator water outlet assembly 34 are widely used in the prior art, so their specific structures will not be elaborated on in this embodiment. The following mainly describes the oscillating water outlet assembly 33.

[0039] The oscillating water outlet assembly 33 includes: an inclined water body 331, a rotating component 332, and a water outlet 333. The water outlet 333 is provided with at least two water outlet holes 3331, and the water outlet direction of the at least two water outlet holes 3331 is radial. Specifically, the two water outlet holes 3331 are respectively deviated from the vertical direction of the water outlet 333 by a certain angle, so that the two water outlet holes 3331 form a certain angle (i.e., radial). In this specific embodiment, three water outlet holes 3331 are provided. The middle water outlet hole 3331 is vertical, and the other two are on the left and right sides of the middle water outlet hole, respectively deviated from the vertical direction by a certain angle. Thus, the water outlet direction of the three water outlet holes 3331 is radial. By setting the water outlet direction of the water outlet holes 3331 radially, the water outlet coverage of the water outlet holes 3331 can be increased. Combined with the oscillation of the water outlet 333, the water outlet coverage area of ​​the water outlet 3331 can be further increased.

[0040] To achieve the oscillating effect, the inclined water body 331 is used to adjust the water flow into a vortex, which drives the rotating component 332 to rotate. The rotating component 332 has an eccentric groove 3321 circumferentially arranged on the side facing the water outlet 333, and the upper end of the water outlet 333 is placed in the eccentric groove 3321. The eccentric groove 3321 refers to the dynamically changing distance between the eccentric groove 3321 and the outer wall of the rotating component 332 along its circumference. Therefore, when the rotating component 332 rotates, the eccentric groove 3321 rotates relative to the water outlet 333, causing the side wall of the eccentric groove 3321 to press against the water outlet 333 and drive the water outlet 333 to oscillate along its axial direction, achieving the oscillating water discharge effect. Taking the vertical position of the water outlet 333 as 0°, the oscillation range of the water outlet 333 in this embodiment is -12° to 12°.

[0041] In order to allow the water outlet 333 to be connected to the eccentric groove 3321, the water outlet 333 includes a ball-head swing arm 3332 placed in the eccentric groove 3321. This allows the water outlet 333 to be connected to the eccentric groove 3321, while the eccentric groove 3321 can also rotate relative to the water outlet 333.

[0042] Furthermore, the inclined water body 331 is provided with a plurality of inclined water holes 3311 spaced along the circumference to adjust the water flow passing through the inclined water holes 3311 into a vortex. The function of the inclined water holes 3311 is to change the axial water flow into a tangential flow. After the tangential water flow hits the blades 3312 of the rotating component 332, it can drive the rotating component 332 to rotate, thereby causing the eccentric groove 3321 to rotate relative to the water outlet 333.

[0043] To connect the inclined water body 331 and the rotating member 332, a connecting post 3313 extends from the side of the inclined water body 331 toward the rotating member 332, and the connecting post 3313 extends into the rotating member 332 so that the rotating member 332 has rotational freedom relative to the inclined water body 331.

[0044] Furthermore, to enhance the cleaning effect of the oscillating water outlet assembly 33, the three water outlet holes 3331 are arranged in a straight line in the radial direction of the water outlet 333. This creates a blade-like water outlet effect, resulting in a strong water impact and good cleaning power.

[0045] The aforementioned oscillating water outlet assembly 33 is installed in the water outlet device 3. The water outlet device 3 includes a spout seat 37 for mounting the spout 333. The spout 333 extends radially outward with a limiting protrusion 3333. The spout seat 37 has a limiting groove 371 that mates with the limiting protrusion 3333. The limiting protrusion 3333 and the limiting groove 371 engage circumferentially with the spout 333. This restricts the rotation of the spout 333, creating a linear oscillating dynamic water outlet instead of a circular (elliptical or circular) rotational water outlet. This oscillating water outlet assembly 33 increases the water outlet range, significantly improving the cleaning range and cleaning power when used for washing dishes in a kitchen space. Furthermore, in this embodiment, the side of the water outlet 333 and the water outlet seat 37 are fitted with an arc surface, which can make way for the swing of the water outlet 333, and at the same time, it is not necessary to set a sealing gasket between the water outlet 333 and the water outlet seat 37.

[0046] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
