Description

Technical Field

[0001] This invention relates to the field of faucet technology, and in particular to a water outlet device. Background Technology

[0002] Kitchen faucets have become an indispensable product in our daily lives. Most kitchen faucets on the market today use hot and cold water valves to control the water flow, and the valve handles are typically located near the inside of the countertop. Because of this placement, users have to bend over to operate the faucet, which can easily cause back pain for those who frequently work in the kitchen. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the aforementioned technical problems in the related art. To this end, the present invention proposes a water outlet device.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] A water outlet device according to an embodiment of the present invention includes:

[0006] The first fixed component has a water inlet, a receiving cavity, a first water outlet channel and a guide hole, wherein the receiving cavity is connected to the first water outlet channel;

[0007] A valve core assembly is disposed within the accommodating cavity. The valve core assembly includes a second fixed component, a diaphragm, a movable pin, and a pressing mechanism. The diaphragm is installed in the second fixed component and divides the interior of the second fixed component into a first cavity, a second cavity, and a third cavity. A first water passage hole is formed on the diaphragm. The first cavity communicates with the second cavity through the first water passage hole. The second cavity communicates with the water inlet. The third cavity communicates with the accommodating cavity. A sealing portion is formed between the second cavity and the third cavity. The first cavity is provided with a pressure relief hole, which communicates with the accommodating cavity. One end of the movable pin has a sealing portion, and the other end is connected to the pressing mechanism.

[0008] The pressing mechanism has a switchable first state and a second state. In the first state, the sealing part blocks the pressure relief hole, and the water pressure in the first cavity drives the diaphragm to press against the sealing part to block the communication between the second cavity and the third cavity. In the second state, the sealing part disengages from the pressure relief hole, and the water pressure in the second cavity drives the diaphragm to disengage from the sealing part to connect the second cavity and the third cavity.

[0009] The control component includes a movable ring and a push rod. The movable ring is slidably connected to the first fixed member and has a ramp. The push rod passes through the guide hole, and its upper end is connected to the pressing mechanism. The lower end of the push rod can abut against the ramp. The movable ring can slide relative to the first fixed member and push the push rod up through the ramp. The push rod can drive the pressing mechanism to switch between a first state and a second state.

[0010] The water outlet device according to embodiments of the present invention has at least the following beneficial effects:

[0011] 1. This invention utilizes a pressing mechanism to drive a movable pin. The movable pin opens or closes the pressure relief hole through a sealing part. The opening and closing of the pressure relief hole directly affects the pressure changes in the second and first cavities located on the upper and lower sides of the diaphragm, thereby affecting the water flow direction. When the pressure relief hole is closed (corresponding to the first state of the pressing mechanism), the water pressure in the first cavity is greater than that in the second cavity. The diaphragm deforms upward and presses against the sealing part to block the connection between the second and third cavities. At this time, the device is in the water-off state. When the pressure relief hole is open (corresponding to the second state of the pressing mechanism), the first cavity is connected to the outside air. The water pressure in the second cavity is greater than that in the first cavity. The diaphragm deforms downward and disengages from the sealing part. The second cavity is connected to the third cavity, and the third cavity becomes the main water outlet passage, achieving the water outlet effect.

[0012] 2. The control component of this invention is used to control the opening and closing of the valve core assembly. In use, the movable ring is pushed horizontally. During this process, the ramp on the movable ring pushes the push rod upward, thereby driving the pressing mechanism to complete one state switch. Thus, each time the movable ring is pushed, the push rod can drive the pressing mechanism to switch between the first state and the second state, realizing the function of turning the water on and off.

[0013] 3. The water outlet device of this invention can be installed at the water outlet end of a faucet, relatively close to the human body, allowing people to easily turn the water flow on and off simply by pushing the movable ring without bending over. This method is low-cost and easy to operate. The water outlet device can also be used as a connector in showerheads, faucets, and other applications requiring on / off water flow, demonstrating high versatility.

[0044] Reference Figure 1-13 A water outlet device, comprising:

[0045] The first fixed component 100 has an inlet 111, a receiving cavity 112, a first water outlet channel 114 and a guide hole 115. The inner peripheral wall of the inlet 111 has internal threads for connecting with products such as faucets and shower heads. The receiving cavity 112 is connected to the inlet 111 and the first water outlet channel 114.

[0046] The valve core assembly 200 is disposed in the accommodating cavity 112. The valve core assembly 200 includes a second fixed member, a diaphragm 220, a movable pin 230, and a pressing mechanism 300. The diaphragm 220 is installed in the second fixed member and divides the interior of the second fixed member into a first cavity 240, a second cavity 250, and a third cavity 260. The diaphragm 220 has a first water passage hole 221. The first cavity 240 communicates with the second cavity 250 through the first water passage hole 221. The second cavity 250 communicates with the water inlet 111. The third cavity 260 communicates with the accommodating cavity 112. A sealing part 271 is formed between the second cavity 250 and the third cavity 260. The first cavity 240 has a pressure relief hole 281, which communicates with the accommodating cavity 112. One end of the movable pin 230 has a sealing part 231, and the other end is connected to the pressing mechanism 300.

[0047] The pressing mechanism 300 has a switchable first state and a second state. In the first state, the sealing part 231 blocks the pressure relief hole 281, and the water pressure in the first cavity 240 drives the diaphragm 220 to press against the sealing part 271 to block the communication between the second cavity 250 and the third cavity 260. In the second state, the sealing part 231 disengages from the pressure relief hole 281, and the water pressure in the second cavity 250 drives the diaphragm 220 to disengage from the sealing part 271 to connect the second cavity 250 and the third cavity 260.

[0048] The control assembly includes a movable ring 400 and a push rod 500. The movable ring 400 is slidably connected to the first fixed member 100. The movable ring 400 has a ramp 410. The push rod 500 passes through the guide hole 115. The upper end of the push rod 500 is connected to the pressing mechanism 300. The lower end of the push rod 500 can abut against the ramp 410. The movable ring 400 can slide relative to the first fixed member 100 and push the push rod 500 through the ramp 410. The push rod 500 can drive the pressing mechanism 300 to switch between a first state and a second state.

[0049] Working principle: In the initial state, water flows from the inlet 111 to the second cavity 250 and then through the first water passage 221 to the first cavity 240. When the pressure relief hole 281 is closed, the first cavity 240 and the second cavity 250 are filled with water. This invention utilizes the pressing mechanism 300 to drive the movable pin 230. The movable pin 230 opens or closes the pressure relief hole 281 through the sealing part 231. The opening and closing of the pressure relief hole 281 directly affects the pressure changes in the second cavity 250 and the first cavity 240 located on the upper and lower sides of the diaphragm 220, thus affecting the water flow direction. When the pressure relief hole 281 is closed (corresponding to the first state of the pressing mechanism 300), the water pressure in the first cavity 240 is greater than the water pressure in the second cavity 250. The diaphragm 220 deforms upwards and presses against the sealing part 271 to block the connection between the second cavity 250 and the third cavity 260. At this time, the device is in the water-off state. When the pressure relief hole 281 is open (corresponding to the second state of the pressing mechanism 300), the first chamber 240 is connected to the outside air, and the water pressure in the second chamber 250 is greater than that in the first chamber 240. The diaphragm 220 deforms downwards and disengages from the sealing part 271, connecting the second chamber 250 to the third chamber 260. The third chamber 260 becomes the main water outlet passage, achieving the water outlet effect. The control component of this invention is used to control the opening and closing of the valve core assembly 200. In use, the movable ring 400 is pushed horizontally. During this process, the ramp 410 on the movable ring 400 pushes the push rod 500 upwards, thereby driving the pressing mechanism 300 to complete one state switch. Thus, each time the movable ring 400 is pushed, the push rod 500 drives the pressing mechanism 300 to switch between the first and second states, realizing the function of switching the water supply on and off.

[0050] In some embodiments of the present invention, reference is made to... Figure 5-7The pressing mechanism 300 includes a pusher tooth 310, a rotating tooth 320, and a second elastic member 330. A second fixing member has a mounting hole 291 communicating with a receiving cavity 112. The inner wall of the mounting hole 291 is alternately provided with a first rib 292 and a first groove 293 along its circumference. The upper end of the first rib 292 forms a first inclined surface 294, a second inclined surface 295, and a second groove 296. The second groove 296 is located between the first inclined surface 294 and the second inclined surface 295. The first groove 293 is lower than the second groove 296. The lower end of the pusher tooth 310 is connected to a push rod 500. The outer peripheral wall of the pusher tooth 310 is provided with a second rib 311. The pusher tooth 310 is located within the mounting hole 291, and the second rib 311... The push tooth 310 is slidably fitted into the first groove 293. The top of the push tooth 310 has several third inclined surfaces 312 along its circumference. The rotating tooth 320 is coaxially fitted with the push tooth 310. The outer peripheral wall of the rotating tooth 320 has a third rib 321. The bottom of the third rib 321 forms a fourth inclined surface 322. The inclinations of the first inclined surface 294, the second inclined surface 295, the third inclined surface 312, and the fourth inclined surface 322 are consistent. The third rib 321 is located above the push tooth 310 and can alternately enter the first groove 293 and the second groove 296. The rotating tooth 320 is connected to the movable pin 230. The upper end of the second elastic member 330 abuts against the second fixed member, and the lower end of the second elastic member 330 abuts against the rotating tooth 320. Water flowing from the pressure relief hole 281 can flow through the gap between the mounting hole 291 and the pressing mechanism 300 to the outlet 121. The pressing mechanism 300 adopts a ballpoint pen refill structure. In the first state, the third protrusion 321 is located in the first groove 293, and the third inclined surface 312 abuts against the fourth inclined surface 322. During switching, the push tooth 310 is pushed upward, which drives the rotating tooth 320 to move upward along the axial direction. When the fourth inclined surface 322 of the rotating tooth 320 moves higher than the first inclined surface 294, the push tooth 310 continues to push, and the rotating tooth 320 will rotate around the center under the action of the second elastic element 330. During this process, the fourth inclined surface 322 slides along the first inclined surface 294 until the third protrusion 321 slides into the second groove 296, completing the switch from the first state to the second state. During the next switch, the pusher tooth 310 is pushed upwards, which in turn drives the rotating tooth 320 to move upwards axially. When the fourth inclined surface 322 of the rotating tooth 320 moves higher than the second inclined surface 295, the pusher tooth 310 continues to push, and the rotating tooth 320 rotates around the center under the action of the second elastic element 330. During this process, the fourth inclined surface 322 slides along the second inclined surface 295 until the third protrusion 321 slides into the first groove 293, completing the switch from the second state to the first state. Because the first groove 293 is lower than the second groove 296, the rotating tooth 320 can stop at two height positions. At the same time, the rotating tooth 320 is connected to the movable pin 230, so that the movable pin 230 also stops at different height positions.

[0051] In some embodiments of the present invention, the movable pin 230 passes through the pressure relief hole 281, and a water-passing gap is left between the outer peripheral wall of the movable pin 230 and the pressure relief hole 281. The sealing part 231 is provided at the upper end of the movable pin 230 and located in the first cavity 240. The first state is when the third protrusion 321 enters the first groove 293, and the second state is when the third protrusion 321 enters the second groove 296. When the pressing mechanism 300 switches from the second state to the first state, the movable pin 230 moves downward to make the sealing part 231 press against the pressure relief hole 281. When the rotating tooth 320 is located in the higher position of the second groove 296, the rotating tooth 320 will drive the movable pin 230 to push upward, so that the sealing part 231 of the movable pin 230 is disengaged from the pressure relief hole 281. At this time, the first cavity 240 is connected to the outside, and the water outlet device is in the water outlet state. When the rotating tooth 320 is in the lower position of the first groove 293, the lower end face of the sealing part 231 will abut against the outer peripheral surface of the pressure relief hole 281, thereby sealing the pressure relief hole 281. At this time, the water outlet device is in the water-off state. It can be understood that in order to improve the sealing effect of the sealing part 231, a sealing gasket can be installed on the pressure relief hole 281, so that the lower end face of the sealing part 231 abuts against the sealing gasket.

[0052] In some embodiments of the present invention, reference is made to... Figure 10-11 The rotating gear 320 has a mating hole 323, and the lower end of the movable pin 230 is inserted into the mating hole 323. The lower surface of the diaphragm 220 has a protrusion 222, which is located directly above the sealing part 231. When the pressing mechanism 300 switches from the second state to the first state, the movable pin 230 can move downward by its own weight and the water pressure in the first cavity 240. When the pressing mechanism 300 switches from the first state to the second state, the bottom wall of the mating hole 323 pushes the movable pin 230. The mating hole 323 and the movable pin 230 are in abutting contact but not fixedly connected. Without the protrusion 222, when the movable pin 230 moves upward, the upper surface of the sealing part 231 may press tightly against the lower surface of the diaphragm 220, causing the water pressure below the sealing part 231 to be greater than the water pressure above it. This would affect the movable pin 230's ability to fall down on its own. The protrusion 222 ensures that there is always space between the upper surface of the sealing part 231 and the lower surface of the diaphragm 220, allowing water to create pressure on the upper surface of the sealing part 231, helping the movable pin 230 to reset. Furthermore, the movable pin 230 is made of metal and can fall under its own weight. It should be noted that the mating hole 323 is mainly for ease of installation, but the connection between the movable pin 230 and the rotating tooth 320 is not limited to the above-described relationship. The movable pin 230 and the rotating tooth 320 can also be fixedly connected, allowing the movable pin 230 to move synchronously with the rotating tooth 320.

[0053] In some embodiments of the present invention, reference is made to... Figure 3 and Figure 14The first fixed component 100 includes an upper body 110 and a lower body 120. An inlet 111, a receiving cavity 112, and a guide hole 115 are formed in the upper body 110. The lower body 120 is located below the upper body 110. A movable ring 400 is located between the upper body 110 and the lower body 120, and the movable ring 400 slides with both the upper body 110 and the lower body 120. A connecting post 113 is formed in either the upper body 110 or the lower body 120, and the upper body 110 and the lower body 120 are fixedly connected by the connecting post 113. The connecting post 113 is hollow inside, forming a first water outlet channel 114. The lower body 120 has an outlet 121, and the first water outlet channel 114 communicates with the outlet 121. The movable ring 400 has a clearance opening 420, and the connecting post 113 is located in the clearance opening 420. Furthermore, the outlet 121 may be provided with internal threads for connection to faucets, shower heads, and other products. The movable ring 400 is confined between the upper body 110 and the lower body 120. The movable ring 400 can only move in the horizontal direction. When the movable ring 400 slides horizontally, the clearance opening 420 moves relative to the fixed connecting post 113. This ensures that the movable ring 400 has enough stroke to trigger the push rod 500, and also ensures that the position of the connecting post 113 is fixed and not affected by the movement of the movable ring 400.

[0054] In some embodiments of the present invention, reference is made to... Figure 2-3 and Figure 14 The movable ring 400 has a first groove 430 at its bottom and a second groove 122 at its top. The first groove 430 and the second groove 122 are perpendicular to each other. The control component also includes a cross key 700, which is formed by connecting a first flat key and a second flat key. The first flat key is located above the second flat key, and the first flat key and the second flat key are perpendicular to each other to form a cross shape. The first flat key slides in the first groove 430, and the second flat key slides in the second groove 122. The cross key 700 allows the movable ring 400 to have only two degrees of freedom in the plane (such as forward and backward and left and right directions), thus inhibiting the circumferential rotation of the movable ring 400.

[0055] In some embodiments of the present invention, a conical groove is formed in the middle of the movable ring 400, the ramp 410 is the inner wall surface of the conical groove, and the push rod 500 is coaxially arranged with the central axis of the conical groove, so that when the movable ring 400 is pushed in any direction, the push rod 500 can be pushed evenly and smoothly through the conical groove to make it rise and fall along the axial direction.

[0056] In some embodiments of the present invention, a first elastic element 600 is also included. The first elastic element 600 is located within the receiving cavity 112 and provides a downward elastic force to the push rod 500. When the user pushes the movable ring 400, the ramp 410 overcomes the elastic force of the first elastic element 600, pushing the push rod 500 upward and triggering the switching state of the pressing mechanism 300. When the external force pushing the movable ring 400 is eliminated, the first elastic element 600 pushes the push rod 500 downward, and the movable ring 400 is reset through the interaction between the ramp 410 and the push rod 500. The first elastic element 600 improves the operating feel and user comfort, and ensures that the movable ring 400 returns to the reference position after each action, preparing for the next pushing operation. It should be noted that the first elastic element 600 is not a necessary component in the present invention. The push rod 500 can reset the movable ring 400 by its own gravity or by manually pushing the movable ring 400. The first elastic element 600 is mainly used to improve convenience and operating feel.

[0057] In some embodiments of the present invention, reference is made to... Figure 2-4 The lower end of the push rod 500 has a fifth inclined surface 510, which forms a sliding fit with the ramp 410. The fifth inclined surface 510 and the ramp 410 form a surface contact, which increases the contact area compared to point contact. Under the same force, it significantly reduces the pressure on the contact surface, thereby reducing wear during long-term use. Moreover, the inclined surface fit has a larger force-bearing area, making the force transmission more continuous and stable, and avoiding jamming or impact.

[0058] In some embodiments of the present invention, reference is made to... Figure 8-13 The second fixing component includes a valve cover 270 and a diaphragm seat 280. The diaphragm seat 280 is located below the valve cover 270. A diaphragm 220 is sandwiched between the valve cover 270 and the diaphragm seat 280. The diaphragm 220 and the diaphragm seat 280 form a first cavity 240. A pressure relief hole 281 is opened in the diaphragm seat 280. Concentric outer ring ribs 272 and inner ring ribs are formed on the lower side of the valve cover 270. The outer ring ribs 272, the inner ring ribs, and the diaphragm 220 form an annular second cavity 250. The valve cover 270 forms a third cavity 260, with an inner rib for the sealing part 271. A vertical water inlet channel 273 and a horizontal second water outlet channel 274 are also formed on the valve cover 270. The upper end of the water inlet channel 273 communicates with the water inlet 111, and the lower end of the water inlet channel 273 communicates with the second cavity 250. The second water outlet channel 274 is located above the second cavity 250, with its inner end communicating with the third cavity 260 and its outer end communicating with the receiving cavity 112. Figure 12-13As shown, the projected area of ​​the first cavity 240 on the lower surface of the diaphragm 220 is S1, the projected area of ​​the third cavity 260 on the upper surface of the diaphragm 220 is S2, and the projected area of ​​the second cavity 250 on the upper surface of the diaphragm 220 is S1-S2. Assuming the inlet water pressure is P0, the diaphragm 220 is subjected to an upward sealing pressure P=P0*(S1-(S1-S2))=P0*S2, meaning the greater the inlet water pressure, the stronger the seal. When the second cavity 250 is connected to the third cavity 260, the projected area of ​​the upper surface of the diaphragm 220 subjected to water pressure changes from S1-S2 to S1, while the projected area of ​​the lower surface of the diaphragm 220 subjected to water pressure is almost 0.

[0059] In some embodiments of the present invention, reference is made to... Figure 6 and Figure 10 The second fixing component also includes a valve body 290, with a mounting hole 291 formed in the valve body 290. A valve cover 270 and a diaphragm seat 280 are installed in the valve body 290. A water passage space is formed between the inner wall of the valve body 290 and the valve cover 270 and diaphragm seat 280. The outer end of the second water outlet channel 274 communicates with the water passage space. A second water passage hole 297 is opened on the valve body 290, and the water passage space communicates with the receiving cavity 112 through the second water passage hole 297. The receiving cavity 112 communicates with the water outlet 121. The valve body 290 is used to integrate and install components such as the valve cover 270 and the diaphragm seat 280, making the valve core assembly 200 modular, facilitating assembly and maintenance, and improving the overall structural stability.

[0060] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
