Description

Technical Field

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

[0002] As people's living standards improve, their demands for kitchen showerheads are also increasing. From single-function to dual-function, and then to triple-function, they have evolved to adapt to the ever-expanding water usage scenarios in the kitchen. Current kitchen showerheads use two independent valve mechanisms, and the third function generally requires holding down the valve to release water. The rocker handles the first and second functions, while the third function requires pressing and releasing the button to reset. The drawbacks of this design are twofold: firstly, it can only achieve three functions and cannot switch between more than three; secondly, this operation can lead to hand fatigue and pain due to prolonged use. Utility Model Content

[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 this utility model is as follows:

[0005] The water outlet device according to an embodiment of the present utility model includes:

[0006] The valve body has an inlet, a main water chamber, a branch water chamber, a reset channel, a switching channel, and at least two outlet channels. The inlet is connected to the main water chamber. The main water chamber has a reset valve port and a switching valve port. The reset valve port is located above the switching valve port. The reset channel is connected to the reset valve port. One end of the switching channel is connected to the switching valve port, and the other end is connected to the branch water chamber. Each outlet channel is connected to the branch water chamber.

[0007] The reset assembly includes a main valve stem and a first elastic element. The main valve stem has a sealing portion located inside the main water chamber. The main valve stem can move upward to block the reset valve port with the sealing portion, and the main valve stem can move downward to block the switching valve port with the sealing portion. The first elastic element provides a downward elastic force to the main valve stem.

[0008] The switching assembly includes a water distribution plate, a switching rod, and a second elastic element. The water distribution plate is located inside the water distribution chamber and has a water passage portion. The switching rod is movably engaged with the water distribution plate. When the switching rod moves downward, it can drive the water distribution plate to rotate so that the water passage portion connects to one of the water outlet channels. The second elastic element provides an upward elastic force to the water distribution plate.

[0009] The rocker plate is rotatable relative to the valve body. The switching rod can be moved downward by an external force, which will cause one end of the rocker plate to press down, so that the other end of the rocker plate will lift the main valve rod upward.

[0010] The water outlet device according to the embodiment of this utility model has at least the following beneficial effects:

[0011] In the initial state, the first elastic element drives the sealing part on the main valve stem to block the switching valve port. Water flowing in from the inlet enters the reset channel through the reset valve port. When the main valve stem is pulled up, the sealing part moves upward with the main valve stem, blocking the reset valve port. At this time, the back pressure in the main water chamber overcomes the elastic force of the first elastic element, allowing the sealing part to remain in the position of blocking the reset valve port even without external force, thus keeping the water flow towards the switching channel. A rocker arm is installed between the main valve stem and the switching rod for linkage. In the initial state, the main valve stem is always in the reset position under the action of the first elastic element. When the switching rod is pressed, one end of the rocker arm is pressed down by the pressure of the switching rod, and the other end of the rocker arm will deflect upward at a certain angle, simultaneously driving the main valve stem upward, opening the switching channel. At this time, pressing the switching rod can realize the switching of at least two water circuits. Regardless of the position, as long as the main valve stem is pressed, it can directly switch to the reset water circuit. When the water is turned off, because the inlet pressure is zero, the main valve stem will reset under the action of the first elastic element, realizing automatic reset when the water is turned off. This invention can automatically reset to the set initial reset function after the water is turned off. It can also be forcibly reset to the reset function during use. The rotating water distribution plate switching structure can realize multi-functional water circuit switching. You only need to press the switching lever to switch functions, without having to hold it down, making it more convenient and easier to use.

[0012] According to some embodiments of the present invention, the valve body further forms a check cavity, the first end of the check cavity is connected to the reset valve port, the second end of the check cavity is connected to the reset channel, and a check valve is provided in the check cavity to prevent water from flowing from the second end of the check cavity to the first end.

The lower part of the main valve stem is located inside the water passage cavity, the reset valve port, and the switching valve port. The upper end of the main valve stem extends out of the valve body. The wall of the water passage cavity is provided with a water outlet, which communicates with the reset channel. The first elastic element is disposed inside the water passage cavity. The upper end of the first elastic element abuts against the top wall of the water passage cavity, and the lower end of the first elastic element abuts against the main valve stem.

[0014] According to some embodiments of the present invention, the valve body is further provided with a mounting hole, the mounting hole being coaxially arranged with the water passage cavity, the main valve stem passing through the mounting hole, and the main valve stem and the mounting hole being in a sliding sealing fit.

[0015] According to some embodiments of the present invention, the switching rod is provided with a first abutting surface, the main valve rod is provided with a second abutting surface, one end of the rocker is provided with a first abutting part, and the other end is provided with a second abutting part. The first abutting part is located below the first abutting surface, and the second abutting part is located below the second abutting surface. When the switching rod is subjected to an external force and moves downward, the first abutting surface can abut against the first abutting part, and at the same time, the second abutting surface abuts against the second abutting part.

[0016] According to some embodiments of the present invention, the reset channel and each of the water outlet channels correspond to a water outlet pattern, wherein the water outlet pattern of one of the water outlet channels is the same as the water outlet pattern of the reset channel.

[0017] According to some embodiments of this utility model, it also includes a water outlet cover. The valve body has a water outlet end face, and the water outlet end face is provided with at least three water outlet holes. One of the water outlet holes is a first water outlet hole, and another water outlet hole is a second water outlet hole. The first water outlet hole is connected to the reset channel, and the second water outlet hole and the remaining water outlet holes are respectively connected to the water outlet channel one by one.

[0035] Reference Figure 1-9 A water outlet device, comprising:

[0036] The valve body 100 comprises an inlet 110, a main water chamber 120, a distribution chamber 130, a reset channel 140, a switching channel 150, and at least two outlet channels 160. The inlet 110 is connected to the main water chamber 120. The main water chamber 120 has a reset valve port 121 and a switching valve port 122. The reset valve port 121 is located above the switching valve port 122. The reset channel 140 is connected to the reset valve port 121. One end of the switching channel 150 is connected to the switching valve port 122, and the other end is connected to the distribution chamber 130. Each outlet channel 160 is connected to the distribution chamber 130. In this embodiment, there are four outlet channels 160.

[0037] The housing 200 and the valve body 100 are installed inside the housing 200;

[0038] The reset assembly includes a main valve stem 300 and a first elastic member 400. The main valve stem 300 has a sealing part 310 located in the main water chamber 120. The main valve stem 300 can move upward to block the reset valve port 121 with the sealing part 310, and the main valve stem 300 can move downward to block the switching valve port 122 with the sealing part 310. The first elastic member 400 provides a downward elastic force to the main valve stem 300.

[0039] The switching assembly includes a water distribution plate 500, a switching rod 600, and a second elastic element 700. The water distribution plate 500 is located inside the water distribution chamber 130. The water distribution plate 500 is provided with a water passage 510. The switching rod 600 is movably engaged with the water distribution plate 500. When the switching rod 600 moves downward, it can drive the water distribution plate 500 to rotate, so that the water passage 510 connects to one of the water outlet channels 160. The second elastic element 700 provides an upward elastic force to the water distribution plate 500.

[0040] The rocker plate 800 is rotatable relative to the valve body 100. The switching rod 600 can be moved downward by external force and drive one end of the rocker plate 800 to press down, so that the other end of the rocker plate 800 lifts the main valve rod 300 upward.

[0041] Working principle: In the initial state, the first elastic element 400 drives the sealing part 310 on the main valve stem 300 to block the switching valve port 122. The water flow from the inlet 110 will enter the reset channel 140 through the reset valve port 121. When the main valve stem 300 is pulled up, the sealing part 310 moves up with the main valve stem 300 and blocks the reset valve port 121. At this time, the back pressure in the main water chamber 120 will overcome the elastic force of the first elastic element 400, so that the sealing part 310 can remain in the position of blocking the reset valve port 121 even without external force, thereby keeping the water flow towards the switching channel 150. A rocker arm 800 is installed between the main valve stem 300 and the switching rod 600 for linkage. Initially, the main valve stem 300 is always in the position of blocking the switching valve port 122 under the action of the first elastic element 400. When the switching rod 600 is pressed, one end of the rocker arm 800 is pressed down by the pressure of the switching rod 600, and the other end of the rocker arm 800 deflects upward at a certain angle, simultaneously driving the main valve stem 300 upward, opening the switching channel 150. At this time, pressing the switching rod 600 can achieve water circuit switching for at least two functions. Regardless of the current position, pressing the main valve stem 300 will directly switch to the reset water circuit. When the water is turned off, because the inlet pressure is zero, the main valve stem 300 will reset under the action of the first elastic element 400, achieving automatic reset when the water is turned off.

[0042] In some embodiments of this utility model, the valve body 100 further forms a check cavity 170. The first end of the check cavity 170 is connected to the reset valve port 121, and the second end of the check cavity 170 is connected to the reset channel 140. A check valve 171 is provided in the check cavity 170 to prevent water from flowing from the second end of the check cavity 170 to the first end. The check valve 171 ensures that the reset channel 140 does not flow back and will not affect the movement state of the main valve stem 300.

[0043] In some embodiments of this utility model, the valve body 100 further forms a water passage cavity 180, which is located above the main water cavity 120. The water passage cavity 180, the reset valve port 121, and the switching valve port 122 are coaxially arranged. The reset valve port 121 connects the water passage cavity 180 and the main water cavity 120. The lower part of the main valve stem 300 is located in the water passage cavity 180, the reset valve port 121, and the switching valve port 122. The upper end of the main valve stem 300 extends out of the valve body 100. The cavity wall of the water passage cavity 180 is provided with a water passage port 181, which communicates with the reset channel 140. The first elastic member 400 is disposed in the water passage cavity 180. The upper end of the first elastic member 400 abuts against the top wall of the water passage cavity 180, and the lower end of the first elastic member 400 abuts against the main valve stem 300. The sealing part 310 is disc-shaped, and a rubber ring is fitted around its outer periphery. The rubber ring can seal against the inner wall of the reset valve port 121 and the switching valve port 122 to achieve a water sealing effect.

[0044] In some embodiments of this utility model, the valve body 100 also has a mounting hole, which is coaxially arranged with the water passage cavity 180. The main valve stem 300 passes through the mounting hole, and the main valve stem 300 and the mounting hole are in a sliding seal fit. To facilitate the molding of the valve body 100 and the installation of various components, the valve body 100 is composed of a main body 190, a first fixing cover 191, a second fixing cover 192, a welding plate 193, a first side cover 194, and a second side cover 195. The water passage cavity 180, the water outlet 181, the reset valve port 121, and the mounting hole are formed on the first fixing cover 191. The first fixing cover 191 is installed above the main water passage cavity 120. The welding plate 193, the second fixing cover 192, and the main body 190 form a water separation cavity 130 and a switching channel 150.

[0045] In some embodiments of this utility model, the switching lever 600 is provided with a first abutment surface 621, the main valve stem 300 is provided with a second abutment surface 321, one end of the rocker 800 is provided with a first abutment portion 810, and the other end is provided with a second abutment portion 820. The first abutment portion 810 is located below the first abutment surface 621, and the second abutment portion 820 is located below the second abutment surface 321. When the switching lever 600 moves downward under external force, the first abutment surface 621 can abut against the first abutment portion 810, and at the same time, the second abutment surface 321 abuts against the second abutment portion 820. In the initial state, the first abutment surface 621 is higher than the second abutment surface 321, and sufficient clearance space is left between the first abutment surface 621 and the first abutment portion 810 for the main valve stem 300 to complete the pressing stroke. Specifically, the switching lever 600 consists of a first lever body 610 and a first button cover 620. The first button cover 620 is fixed to the top of the first lever body 610, and a first abutting surface 621 is formed on the inner side of the first button cover 620. The main valve lever 300 consists of a second lever body 320 and a second button cover 330. The second button cover 330 is fixed to the top of the second lever body 320, and a second abutting surface 321 is formed on the second lever body 320. The first button cover 620 and the second button cover 330 provide users with a good pressing feel. The outer casing 200 is provided with two through holes for the first button cover 620 and the second button cover 330 to pass through.

[0046] In some embodiments of this utility model, the reset channel 140 and each water outlet channel 160 correspond to a water outlet pattern, wherein the water outlet pattern of one water outlet channel 160 is the same as the water outlet pattern of the reset channel 140. Pressing the switching lever 600 can also switch to the water outlet pattern of the reset water path, which is convenient to operate and does not require switching between two buttons.

[0047] In some embodiments of this utility model, a water outlet cover 900 is also included. The valve body 100 forms a water outlet end face with five water outlet holes. One water outlet hole is a first water outlet hole 196, and another water outlet hole is a second water outlet hole 197. The first water outlet hole 196 is connected to the reset channel 140, and the second water outlet hole 197 and the other three water outlet holes are respectively connected to the water outlet channel 160. The water outlet cover 900 is connected to the water outlet end face and has four water outlet chambers. The first water outlet hole 196 and the second water outlet hole 197 are connected to one of the water outlet chambers, and the other three water outlet chambers are connected to the other three water outlet holes respectively. The reset channel 140 and one of the water outlet channels 160 share a water outlet chamber, so that the reset channel 140 and one of the water outlet channels 160 can both output the same type of water, such as sparkling water.

[0048] In some embodiments of this utility model, the top of the water distribution cavity 130 is formed with a shaft hole 131 and a water outlet 132. The number of water outlets 132 is the same as the number of water outlet channels 160. The water outlets 132 are arranged in a ring array with the shaft hole 131 as the center. The water outlets 132 are connected to the water outlet channels 160 one by one. The switching rod 600 passes through the shaft hole 131. The water distribution plate 500 abuts against the top of the water distribution cavity 130. The water passage part 510 is aligned with one of the water outlets 132. The plate body of the water distribution plate 500 blocks the other water outlets 132. The second elastic member 700 is located below the water distribution plate 500. The upper end of the second elastic member 700 abuts against the water distribution plate 500, and the lower end of the second elastic member 700 abuts against the cavity wall of the water distribution cavity 130.

[0049] In some embodiments of this utility model, the switching lever 600 and the water distribution plate 500 are movably engaged by a pressing and rotating structure. The pressing and rotating structure includes a first ratchet 520 disposed on the end face of the water distribution plate 500 and a second ratchet 630 disposed on the outer periphery of the switching lever 600. The number of the first ratchet 520 and the second ratchet 630 is the same as the number of the water outlet channels 160. The first ratchet 520 is arranged circumferentially along the water distribution plate 500, and the second ratchet 630 is arranged at intervals circumferentially along the switching lever 600. A limiting groove 640 is formed between two adjacent second ratchet 630s. The hole wall of the shaft hole 131 is provided with a vertical... The limiting rib 133 slides in engagement with the limiting groove 640. The upper end face of the first ratchet 520 is a first inclined surface 521, which slopes downward circumferentially. The lower end face of the second ratchet 630 is a second inclined surface 631. The first inclined surface 521 and the second inclined surface 631 engage and abut. In the initial state, the uppermost end of the first inclined surface 521 is higher than the lowermost end of the limiting rib 133. In the switching state, the downward movement of the switching rod 600 can push the first ratchet 520 to move along the limiting rib 133 until the uppermost end of the first inclined surface 521 is lower than the lowermost end of the limiting rib 133. Furthermore, the bottom surface of the limiting rib 133 is a third inclined surface 1331, which can engage with the first inclined surface 521. In the initial state, the water distribution plate 500, under the action of the second elastic element 700, seals several water outlets 132, connecting only one water outlet channel 160. When the switching rod 600 overcomes the elastic force of the second elastic element 700 and pushes the water distribution plate 500 to move, the water distribution plate 500 will detach from the top of the water distribution cavity 130. When the switching rod 600 moves to the uppermost end of the first inclined surface 521 below the lowermost end of the limiting rib 133, under the action of the second elastic element 700, the water distribution plate 500 rotates along the second inclined surface 631 at a certain angle, until the first inclined surface 521 contacts the third inclined surface 1331, and the force is released. At this time, under the action of the second elastic element 700, the first inclined surface 521 slides along the third inclined surface 1331, causing the water distribution plate 500 to rotate again until the side of the first ratchet 520 acts on the limiting rib 133 again, completing one switching action.

[0050] In some embodiments of this utility model, the valve body 100 is provided with a mounting base 198, and the rocker plate 800 is rotatably connected to the mounting base 198 via a rotating shaft. The rotating shaft is located between the first abutment portion 810 and the second abutment portion 820 of the rocker plate 800.

[0051] Although embodiments of the present 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 present invention, the scope of which is defined by the claims and their equivalents.
