[0031] The following further describes the present invention in conjunction with the drawings and specific embodiments.

[0032] Certain directional terms used hereinafter to describe the accompanying drawings, such as "inner", "outer", "upper", "lower" and other directional terms, will be understood to have their normal meanings and refer to those directions involved when normally viewing the accompanying drawings. Unless otherwise specified, the directional terms described in this specification are generally in accordance with the conventional directions understood by those skilled in the art.

[0033] The terms "first", "the first", "second", "the second" and their similar terms used in the present invention do not indicate any order, quantity or importance in the present invention, but are used to distinguish one component from other components.

[0034] Referring to Figures 1-11 , a press-type water outlet device 100, comprising: a housing 1, which includes a valve chamber 11 and a water inlet passage 12, a first water outlet passage 13 and a second water outlet passage 14 communicating with the valve chamber 11, wherein the outlet 131 of the first water outlet passage 13 is inclined upward or vertically upward; a pressing and switching device 2, slidably arranged axially in the valve chamber 11, which is used to connect the water inlet passage 12 with the first water outlet passage 13 or the second water outlet passage 14; a shielding piece 3, arranged on the pressing and switching device 2, when the pressing and switching device 2 slides and switches to connect the water inlet passage 12 and the second water outlet passage 14, the shielding piece 3 slides along with the pressing and switching device 2 and shields the outlet 131 of the first water outlet passage 13.

[0035] In this embodiment, for the convenience of users, the angle between the outlet 131 of the first water outlet passage 13 and the horizontal plane is 0°-90°.

[0036] The housing 1 includes an outer shell 15, a water dividing body 16 and a water outlet body 17. The water dividing body 16 and the water outlet body 17 are detachably clamped together and define the water inlet passage 12, the first water outlet passage 13 and the second water outlet passage 14. The valve chamber 11 extends in the water dividing body 16 and the water outlet body 17. The inlet 132 of the first water outlet passage 13 and the inlet 142 of the second water outlet passage 14 are arranged on the water outlet body 17. The outlet 141 of the second water outlet passage 14 is inclined downward or vertically downward. A bubbler assembly 4 is further arranged at the outlet 141 of the second water outlet passage 14, and the bubbler assembly 4 can be used by users for conventional operations such as washing hands.

[0037] The outer shell 15 is sleeved outside the water distributor 16 and the water outlet body 17. Specifically, one end of the water distributor 16 is provided with a water inlet 161, which is communicated with an external water source. The other end of the water distributor 16 is detachably clamped with the water outlet body 17. The water outlet body 17 is provided with a lug snap ring 171 extending towards the water distributor 16. The water distributor 16 radially extends out a clamping block 162. The water distributor 16 is butted with the water outlet body 17 to make the lug snap ring 171 and the clamping block 162 clamped.

[0038] A flow stabilizer 5 is arranged in the first water outlet channel 13. In some simple replacements, the flow stabilizer can also be replaced with a flow limiter. A flow rectifier 6 is also arranged adjacent to the outlet of the first water outlet channel 13. The flow stabilizer 5 is arranged on the water outlet body 17, and the flow rectifier 6 is arranged on the water outlet body 17. The flow stabilizer 5 can limit the flow rate passing through the first water outlet channel 13 per unit time to a constant value. The flow rectifier 6 can shape the water passing through the outlet of the first water outlet channel 13 into a required shape, such as sheet water, columnar water, etc. The combined action of the flow stabilizer 5 and the flow rectifier 6 can prevent the water pressure of the water flow ejected from the outlet 131 of the first water outlet channel 13 from being too large or too small, resulting in the user being splashed by water when gargling.

[0039] The valve cavity 11 extends from one end to the other end along the length direction of the housing 1. The inlet 132 of the first water outlet channel 13, the outlet 121 of the water inlet channel 12, and the inlet 142 of the second water outlet channel 14 are sequentially arranged at intervals along the axial direction of the valve cavity 11. The pressing and switching device 2 includes a switching shaft 21 sliding in the valve cavity 11. The switching shaft 21 is provided with a communication space. The switching shaft 21 slides back and forth to make the outlet 121 of the water inlet channel 12 communicate with the inlet 132 of the first water outlet channel 13 or the inlet 142 of the second water outlet channel 14 through the communication space respectively.

[0040] The switching shaft 21 slides a certain distance to make the communication space communicate with the water inlet channel 12 and the first water outlet channel 13. This sliding distance is greater than the dimension of the outlet 131 of the first water outlet channel 13 along the sliding direction of the switching shaft 21, which can prevent the first water outlet channel 13 from being conducted due to the user's misoperation when a part of the shielding piece 3 still shields the outlet 131 of the first water outlet channel 13.

[0041] The push-to-switch device 2 also includes a sealing member 22 which is circumferentially arranged and presses against the inner wall of the valve cavity 11. The connecting space is separated into a first connecting interval 2111 and a second connecting interval 2112 by the sealing member 22. The first connecting interval 2111 is connected to the inlet 132 of the first water outlet channel 13, and the second connecting interval 2112 is connected to the inlet 142 of the second water outlet channel 14. The sliding of the switching shaft 21 drives the sealing member 22 to slide and connects the outlet 121 of the water inlet channel 12 to the first connecting interval 2111 or the second connecting interval 2112. The push-to-switch device 2 also includes two waterproof pads 24 which are axially spaced on both sides of the sealing member 22. The two waterproof pads 24 are spaced apart from the sealing member 22 and define the first connecting interval 2111 and the second connecting interval 2112.

[0042] See also Figure 4 When the second connecting interval 2112 connects the water inlet channel 12 and the second water outlet channel 14, the shielding piece 3 shields the outlet 131 of the first water outlet channel 13, and water flows into the bubbler assembly 4 and flows out downward.

[0043] See also Figure 5 When the pressing switching device 2 slides to the point where the shielding piece 3 does not cover the outlet 131 of the first water outlet channel 13, the second connecting gap 2112 is still connected to the water inlet channel 12 and the second water outlet channel 14, which can ensure that water flows into the first water outlet channel 13 when the shielding piece 3 covers the outlet 131 of the first water outlet channel 13.

[0044] See also Figure 6 When the push-to-switch device 2 slides to connect the first connecting interval 2111 to the water inlet channel 12 and the first water outlet channel 13, water flows through the flow stabilizer 5 and the rectifier 6 and then sprays out from the first water outlet channel 13 in an upward tilt or vertically upward direction. Specifically, the angle between the outlet 131 of the first water outlet channel 13 and the horizontal plane is 70 degrees.

[0045] The push-to-switch device 2 further includes a button 25 and an intermittent motion mechanism 26, wherein the intermittent motion mechanism 26 is connected to the button 25 and the switch shaft 21 by transmission, and the button 25 is acted upon by an external force and drives the switch shaft 21 through the intermittent motion mechanism 26 to move between a first switching position connected to the inlet 132 of the first water outlet channel 13 and a second switching position connected to the inlet 142 of the second water outlet channel 14, and the intermittent motion mechanism 26 enables the switch shaft 21 to slide axially along the valve chamber 11 and be fixed between the first switching position and the second switching position.

[0046] The intermittent motion mechanism 26 also includes a return spring 261 that presses between the switching shaft 21 and the housing 1. One end of the switching shaft 21 is connected to an upper ratchet element 262. One end of the button 25 has a lower ratchet element 263 and slides in the valve chamber 11. Pressing the button 25 drives the lower ratchet element 263 to transmit the upper ratchet element 262 to slide back and forth intermittently, thereby realizing the back and forth sliding of the switching shaft 21.

[0047] Specifically, the upper ratchet element 262 has a disc-shaped upper disk body 2621, and has a plurality of ratchets protruding in the direction opposite to the pressing direction of the button 25. The outer peripheral wall surface of the upper disk body 2621 cooperates with the inner peripheral wall surface of the valve cavity 11 and slides in the inner peripheral wall surface of the valve cavity 11. The lower ratchet element 263 has a disc-shaped lower disk body 2631, and has a plurality of ratchets protruding in the direction of the pressing direction of the button 25. The outer peripheral wall surface of the lower disk body 2631 cooperates with the inner peripheral wall surface of the valve cavity 11 and slides in the inner peripheral wall surface of the valve cavity 11. The upper ratchet element 262 and the lower ratchet element 263 are in abutment with each other, and the inner peripheral wall of the valve cavity 11 also has a convex strip 266 for slidingly guiding the lower ratchet element 263. The ratchet element 263 and the convex strip 266 constitute a mechanism based on the structural principle of the automatic pen. Each time the button 25 is pressed, the upper ratchet element 262 rotates circumferentially by a certain angle. Since each ratchet of the upper ratchet element 262 has a limiting groove 264 and a giving groove 265 on both sides, when the upper ratchet element 262 falls back onto the convex strip 266 under the action of the spring, the convex strip 266 will fall on the limiting groove 264 or the giving groove 265 in turn. When the convex strip 266 passes through the giving groove 265, the switching shaft 21 switches to one of the first switching position and the second switching position. When the convex strip 266 abuts against the limiting groove 264, the switching shaft 21 switches to the other of the first switching position and the second switching position.

[0048] Specifically, the convex strip 266 passes through the give way groove 265 and allows the switching shaft 21 to slide freely in the valve cavity 11. Due to the action of the spring, the switching shaft 21 and the button 25 are kept away from the valve cavity 11. When the convex strip 266 falls into the limit groove 264, the upper ratchet element 262 is restricted from sliding in the valve cavity 11. Because the upper ratchet element 262 can rotate relative to the axis of the switching shaft 21, the rotation of the upper ratchet element 262 during the switching process will not drive the switching shaft 21 to rotate. The upper ratchet element 262 only transmits its axial movement along the valve cavity to the switching shaft 21, so that the switching shaft 21 intermittently switches between the first switching position and the second switching position.

[0049] As described above, it is only the preferred specific implementation manner of the present invention. However, the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention who makes non-substantial modifications to the present invention using this concept shall fall within the scope of infringement of the protection scope of the present invention.
