Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 to 6, a force-saving water outlet device with a hidden water outlet according to an embodiment of the present invention includes a main body 10, a first water outlet nozzle 20, a valve core 60, and a telescopic mechanism 30, wherein the water outlet device may be a faucet, a pull head, a shower head, or a spray rod, and the water outlet device is described in detail below with reference to the pull head as an example.
The main body 10 includes a main body 11 and a casing 12, the casing 12 is a cylindrical structure with two ends penetrating, the main body 11 has a water inlet passage 111, a valve chamber 114 and a first valve port 112. The first nozzle 20 is telescopically installed in the main body 10, the first nozzle 20 has a first outlet 21, and the first outlet 21 is communicated with the water inlet channel 111 through a first valve port 112.
The valve core 60 slides in the valve cavity 114 and is in linkage fit with the first water nozzle 20 to open and close the first valve port 112, and a force balance part 61 is formed on the valve core 60, and the function of the force balance part 61 is described in detail below.
The telescoping mechanism 30 is movably disposed in the main body 10 and is in linkage fit with the valve core 60 and the first water outlet nozzle 20, the telescoping mechanism 30, the valve core 60 and the first water outlet nozzle 20 are coaxially arranged, and the valve core 60 is located between the telescoping mechanism 30 and the first water outlet nozzle 20. When the first nozzle 20 is pressed, the valve core 60 slides between the first position and the second position along the axial direction of the main body 10 under the action of the telescopic mechanism 30.
When the valve core 60 is in the first position, the valve core 60 opens the first valve port 112 and the first water nozzle 20 slides to an extended position relative to the main body 10 so that the first water outlet 21 is exposed out of the main body 10, and at this time, the force balance portion 61 receives a water pressure acting force opposite to the water flow direction in the valve core 60, so that the valve core 60 is in a state of being balanced by the water pressure acting force; thus, when the first water outlet nozzle 20 is pressed in a water outlet state of the first water outlet nozzle 20, the water pressure acting force applied to the valve core 60 is balanced, and the pressing force for driving the first water outlet nozzle 20 does not need to overcome the water pressure acting force additionally, so that labor can be saved, and the operation hand feeling is better. Make when first delivery port 21 goes out water through setting up stress balance portion 61, case 60 can receive the water pressure effort opposite with the rivers opposite direction in the case 60 to make the water pressure effort that case 60 received balanced, design benefit, simple structure.
When the valve core 60 is in the second position, the valve core 60 closes the first valve port 112 and the first water nozzle 20 slides to a retracted position relative to the main body 10 to hide the first water outlet 21 in the main body 10.
The valve core 60 is provided with a first sealing member 63 and a second sealing member 64, the first sealing member 63 seals or opens the first valve port 112, and the second sealing member 64 is arranged on the force balance part 61 and is in sealing sliding fit with the inner wall of the valve cavity 114. When the valve core 60 is located at the first position, the direction of the water pressure received by the force balance portion 61 is opposite to the direction of the water pressure received by other portions of the valve core 60 except the force balance portion 61, so that the acting force of the water flow on the direction in which the valve core 60 slides along the first water outlet nozzle 20 and extends out of the main body 10 can be counteracted, and the acting force of the water pressure received by the valve core 60 keeps balance. The first seal 63 is preferably an O-ring seal and the second seal 64 is preferably a Y-ring seal.
The side of the force balance part 61 facing away from the first sealing element 63 and the inner wall of the valve cavity 14 form a sealing cavity 1141, and the sealing cavity 1141 is provided with an exhaust hole 1142 communicating with the outside, so as to prevent the sealing cavity 1141 from being suppressed, and to enable the first water nozzle 20 to be smoothly pressed.
In the water outlet device of the present embodiment, the first water nozzle 20 is disposed at one end of the housing 12 in the axial direction, when the first water nozzle 20 is located at the extended position, the first water outlet 21 is exposed from the end of the housing 12 to the housing 12, and when the first water nozzle 20 is located at the retracted position, the first water outlet 21 is retracted from the end of the housing 12 to the housing 12. When the first water outlet nozzle 20 is at the extended position, the first water outlet 21 is exposed out of the housing 12, the valve core 60 opens the first valve port 112, and the water inlet channel 111 is communicated with the first water outlet 21 through the first valve port 112; when the first water nozzle 20 is in the retracted position, the first water outlet 21 is hidden in the housing 12, the valve core 60 closes the first valve port 112, and the water inlet channel 111 is disconnected from the first water outlet 21.
In the process that the first water outlet nozzle 20 moves from the retracted position to the extended position, after the first water outlet 21 is completely exposed out of the main body 10, the water inlet channel 111 is communicated with the first water outlet 21; during the movement of the first nozzle 20 from the extended position to the retracted position, just before the first outlet 21 retracts into the main body 10, the water inlet channel 111 is disconnected from the first outlet 21. Therefore, the problem that water splashes everywhere due to the fact that a part of the water flowing out of the first water outlet 21 is sprayed onto the main body 10 can be avoided, and the use experience is better.
In this embodiment, in the process that the first water nozzle 20 moves from the retracted position to the extended position, the stroke of the first water nozzle 20 moving until the first water outlet 21 is completely exposed from the main body 10 is less than or equal to the stroke of the valve core 60 moving until the first valve port 112 is just opened; in the process that the first water outlet nozzle 20 moves from the extended position to the retracted position, the stroke of the first water outlet nozzle 20 moving to the first water outlet 21 just retracting into the main body 10 is greater than or equal to the stroke of the valve core 60 moving to just close the first valve port 112, so that the problem that water flows everywhere due to the fact that a part of water flowing out from the first water outlet 21 sprays onto the main body 10 can be avoided, and the use experience is better.

When the pushing element 32 pushes the rotating element 33 until the rotating element 33 loses the circumferential limit with the sleeve 31, the rotating element 33 rotates by a preset angle to be clamped with the first positioning slot 311 or the second positioning slot 312 under the action of the first ratchet tooth 321 and the second ratchet tooth 331. The pushing member 32 is pushed to reciprocate to drive the rotating member 33 to alternately engage with the first positioning slot 311 and the second positioning slot 312, so that the pushing member 32 moves relative to the sleeve 31, and the pushing member 32 drives the first water outlet nozzle 20 to move between the extended position and the retracted position through the valve core 60.
