Description

Technical Field

[0001] This invention belongs to the field of bathroom technology, and specifically relates to a two-inlet, two-outlet valve core. Background Technology

[0002] A valve core is a control component inside a valve (such as a faucet, mixing valve, shower switch, etc.). Its main function is to control the opening and closing of fluids, the flow rate, and the water temperature.

[0003] For example, Chinese patent CN222351511U discloses a valve core and faucet, including a valve plate control assembly with a control water channel, a base, and a water outlet controlled by the valve plate control assembly. The valve plate control assembly includes a stationary valve plate and a moving valve plate. The moving valve plate has a mixing chamber that is connected to the water outlet. The stationary valve plate and the base are provided with two water inlet channels. It also includes a valve stem and a rotating component. The valve stem can rotate to control the water temperature. The valve stem can translate on the first moving groove of the rotating component, thereby driving the moving valve plate to move synchronously so that the mixing chamber is connected to the water inlet channel, realizing the water outlet of the valve core.

[0004] This type of valve core controls the rotation of the moving valve plate via the valve stem, thus controlling the opening and closing of the fluid and adjusting the water temperature. However, it is not suitable for simultaneous use with a kitchen faucet and a waterfall shower. Therefore, an applicant developed a dual-inlet, dual-outlet valve core and water outlet device (publication number CN213206642U). This valve core has two water outlets, which can be used to connect to a faucet and a waterfall shower respectively. Water temperature can be adjusted by rotating the valve core horizontally. However, this type of valve core uses a lever to control the sliding of the moving plate, thereby switching the water outlet path or adjusting the water flow. The distinction between adjusting the water flow and switching the water outlet path is not clear, making it difficult for users to accurately control these two functions. In other words, the design of this valve core is unreasonable, inconvenient to use, and very likely to cause users to accidentally switch the water path when adjusting the water flow. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a two-inlet, two-outlet valve core. The technical problem to be solved by this invention is: how to effectively improve the ease of use of the dual-water-circuit valve core.

[0006] The above-mentioned technical objectives of the present invention can be achieved through the following technical solutions: A dual-inlet, dual-outlet valve core includes a housing, a fixed valve plate, a movable valve plate, a base, and a control component. The housing has an inner cavity, in which the fixed and movable valve plates are stacked. The base is connected to the housing and limits the position of the fixed valve plate. The fixed valve plate has two symmetrically arranged water passages, one cold water inlet, one hot water inlet, and one outlet. The second water passage includes a second cold water inlet, a second hot water inlet, and a second outlet. The control component is connected to the movable valve plate, which has an eccentrically arranged connecting groove. The control component controls the movable valve plate to rotate, causing the connecting groove to connect the first or second water passage. The control component also controls the movable valve plate to slide, thereby controlling the communication area between the first cold water inlet and / or the first hot water inlet and the first outlet, or controlling the communication area between the second cold water inlet and / or the second hot water inlet and the second outlet.

[0007] In the aforementioned two-inlet, two-outlet valve core, the base has a cold water channel, a hot water channel, an outlet channel one, and an outlet channel two. The cold water channel is connected to both cold water outlet one and cold water outlet two. The hot water channel is connected to both hot water outlet one and hot water outlet two. The outlet channel one is connected to outlet one, and the outlet channel two is connected to outlet two.

[0008] In the aforementioned two-inlet, two-outlet valve core, the base has a hook and a limiting post, the outer shell has a groove that mates with the hook, and the limiting post abuts against the side wall of the inner cavity.

[0009] In the aforementioned two-inlet, two-outlet valve core, the control component includes a valve stem, a connecting seat, and a paddle. The connecting seat is rotatably disposed in the inner cavity. The valve stem is hinged to the connecting seat, and the outer end of the valve stem is located outside the outer shell. The paddle is slidably connected to the lower end of the connecting seat and is connected to the movable valve plate. The valve stem can drive the paddle to rotate and / or slide.

[0010] In the aforementioned two-inlet, two-outlet valve core, the side of the connecting seat is provided with a protrusion, and the inner cavity has a stroke groove for the protrusion to rotate.

[0011] In the above-mentioned two-inlet and two-outlet valve core, the protrusion has an assembly groove facing the stroke groove. A preload spring and a ejector pin are provided in the assembly groove. The stroke groove has a positioning groove. When the assembly groove rotates to the positioning groove, the preload spring pushes the ejector pin into the positioning groove. At this time, the connecting groove is covered by the fixed valve plate.

[0012] In the above-mentioned two-inlet, two-outlet valve core, the positioning groove is located in the middle of the stroke groove, and the side wall of the positioning groove has a guide surface.

[0013] In the above-mentioned two-inlet, two-outlet valve core, the first cold water inlet and the first hot water inlet are both located outside the first outlet, and the second cold water inlet and the second hot water inlet are both located outside the second outlet; a sealing surface is provided between the first cold water inlet and the second cold water inlet, and the sealing surface can cover the connecting groove.

[0014] In the aforementioned two-inlet, two-outlet valve core, the bottom of the connecting seat has a guide groove, and the paddle has a guide strip that slides with the guide groove; the lower part of the protrusion has an arc-shaped protrusion, and the guide strip has a clearance groove that matches the arc-shaped protrusion.

[0015] In the aforementioned two-inlet, two-outlet valve core, the lower end of the base has a connecting foot, which is penetrated by a cold water channel, a hot water channel, an outlet channel one, and an outlet channel two, and each of the cold water channel, the hot water channel, the outlet channel one, and the outlet channel two is provided with a threaded joint.

[0016] In summary, the advantages of this invention compared to the prior art are as follows: Cold water enters the valve core through the cold water channel, and hot water enters the valve core through the hot water channel. The cold water channel simultaneously supplies water to both cold water inlet 1 and cold water inlet 2, and the hot water channel simultaneously supplies water to both hot water inlet 1 and hot water inlet 2. Rotating the control component drives the moving valve plate to rotate. When the connecting groove connects to water circuit 1, the connecting groove connects cold water inlet 1 and / or hot water inlet 1 to outlet 1, and water can then be discharged from outlet channel 1. Rotating the control component in the opposite direction, so that the connecting groove connects to water circuit 2, the connecting groove connects cold water inlet 2 and / or hot water inlet 2 to outlet 2, and water can then be discharged from outlet channel 2. In other words, the horizontal rotation of the moving valve plate can achieve switching between the two water circuits and water temperature adjustment. The outlet water temperature of the two water circuits is independently controlled and does not interfere with each other. When the control component controls the switching of water circuits, the operation direction is opposite. The design is reasonable and can effectively improve the ease of use of the dual water circuit valve core and avoid user misoperation.

[0017] When the moving valve plate rotates horizontally, the valve core only discharges the basic water flow, which is suitable for small water flow situations. The user can drive the moving valve plate to slide by moving the valve rod, thereby increasing the connection area between cold water port one and / or hot water port one and outlet one (or the connection area between cold water port two and / or hot water port two and outlet two), thus increasing the water flow.

[0018] When the moving valve plate rotates horizontally, water circuit one connects to outlet one first, meaning cold water flows out of outlet one first. As the moving valve plate continues to increase its rotation amplitude, hot water outlet one can connect to outlet one, thereby increasing the outlet water temperature. Similarly, water circuit two connects to outlet two first, meaning that when the valve core is opened, cold water is discharged first, and the outlet water temperature is adjusted according to actual needs, which is more in line with the user's usage habits.

Detailed Implementation

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] A type of two-inlet, two-outlet valve core, such as Figures 1-11 As shown, the device includes a housing 100, a fixed valve plate 200, a movable valve plate 300, a base 400, and a control component 500. The housing 100 has an inner cavity 110. The fixed valve plate 200 and the movable valve plate 300 are stacked in the inner cavity 110. The base 400 is connected to the housing 100 and limits the position of the fixed valve plate 200. The fixed valve plate 200 has two symmetrically arranged water passages 210 and 220. Water passage 210 includes a cold water inlet 211, a hot water inlet 212, and an outlet 213. Water passage 220 includes a cold water inlet 221, a hot water inlet 222, and an outlet 223. The control component 500 is connected to the movable valve plate 300. The upper end of the control component 500 is located outside the housing 100. The movable valve plate 300 has an eccentrically arranged connecting groove 310. The control component 500 controls the rotating valve plate 300 to make the connecting groove 310 connect water passage 210 or water passage 220; The control component 500 controls the sliding of the movable valve plate 300, thereby controlling the communication area between the cold water inlet 211 and / or the hot water inlet 212 and the outlet 213, or controlling the communication area between the cold water inlet 221 and / or the hot water inlet 222 and the outlet 223, thereby adjusting the water output of the outlet 213 or the outlet 223.

[0023] When the connecting groove 310 is connected to water passage 210, the connecting groove 310 connects the cold water inlet 211 and / or the hot water inlet 212 to the outlet 213, allowing cold water and / or hot water to be discharged from the connecting groove 310 and the outlet 213. At this time, the connecting groove 310 is always connected to the outlet 213. Adjusting the connection ratio between the cold water inlet 211, the hot water inlet 212, and the connecting groove 310 adjusts the water temperature at the outlet 213. When water passage 220 is connected, the passive valve plate 300 is closed. Similarly, when the connecting groove 310 is connected to water passage 220, the connecting groove 310 connects the cold water port 221 and / or the hot water port 222 to the outlet 223. By adjusting the connection ratio between the cold water port 221, the hot water port 222 and the connecting groove 310, the outlet water temperature of outlet 223 can be adjusted. At this time, the passive valve plate 300 of water passage 210 is closed. This valve core only allows one water passage to be opened at a time.

[0024] like Figures 5-7 As shown, the base 400 has a cold water channel 410, a hot water channel 420, a first outlet channel 430, and a second outlet channel 440. The opening of the end of the cold water channel 410 near the fixed valve plate 200 is enlarged, and the cold water channel 410 can simultaneously connect to the first cold water port 211 and the second cold water port 221, supplying water to both the first and second cold water ports simultaneously. The opening of the hot water channel 420 near the fixed valve plate 200 is enlarged, and the hot water channel 420 can simultaneously connect to the first hot water port 212 and the second hot water port 222, supplying water to both the first and second hot water ports simultaneously. The first outlet channel 430 is connected to the first outlet 213, and the second outlet channel 440 is connected to the second outlet 223.

[0025] The base 400 is provided with hooks 450 and limiting posts 460 at intervals. The outer shell 100 has a groove 120 that mates with the hooks 450. The limiting posts 460 abut against the side wall of the inner cavity 110 to prevent abnormal deformation of the outer shell 100. The side wall of the fixed valve plate 200 has a limiting groove 230 that matches the limiting post 460. The limiting post 460 and the limiting groove 230 cooperate to limit the circumferential movement of the fixed valve plate 200, thereby preventing the fixed valve plate 200 from shifting relative to the base 400.

[0026] like Figures 1-6 As shown, the control assembly 500 includes a valve stem 510, a connecting seat 520, and a paddle 530. The connecting seat 520 is rotatably disposed on the upper end of the inner cavity 110. The valve stem 510 is hinged to the connecting seat 520, and the outer end of the valve stem 510 is located outside the outer shell 100. The paddle 530 is slidably connected to the lower end of the connecting seat 520, and the lower end of the paddle 530 is engaged with the movable valve plate 300. The valve stem 510 can drive the paddle 530 and the movable valve plate 300 to rotate and / or slide synchronously.

[0027] Furthermore, the side of the connecting seat 520 is provided with a protrusion 521, and the inner cavity 110 has a stroke groove 130 for the protrusion 521 to rotate, that is, the stroke groove 130 controls the rotation stroke of the connecting seat 520 and the moving valve plate 300.

[0028] The protrusion 521 has an assembly groove 522 facing the stroke groove 130. A preload spring 5221 and a ejector pin 5222 are arranged in sequence in the assembly groove 522. The preload spring 5221 presses the outer end of the ejector pin 5222 against the stroke groove 130, thereby increasing the rotation resistance of the connecting seat 520. The stroke groove 130 has a positioning groove 131. After the assembly groove 522 rotates to the direction of the positioning groove 131, the preload spring 5221 pushes the end of the ejector pin 5222 into the positioning groove 131. At this time, the connecting groove 310 is covered by the fixed valve plate 200, and the valve core is in the closed state. In this embodiment, the positioning groove 131 serves as the center of the switching stroke between water path one 210 and water path two 220, and provides a signal when the valve core is closed. It is necessary to further increase the external force applied to the valve stem 510 to rotate the connecting seat 520, so that the ejector pin 5222 can be dislodged from the positioning groove 131, thereby opening the valve core. This also improves the user's operating feel when switching water paths.

[0029] The positioning groove 131 is located in the middle of the stroke groove 130, and the side wall of the positioning groove 131 has a guide surface 132, which is used to guide the end of the ejector pin 5222 into and out of the positioning groove 131.

[0030] Cold water inlet 1 (211) and hot water inlet 1 (212) are both located outside outlet 1 (213), and cold water inlet 221 and hot water inlet 222 are both located outside outlet 223. A sealing surface 240 is provided between cold water inlets 1 (211) and 221. When the passive valve plate 300 of water passage 1 (210) and water passage 2 (220) is covered, the sealing surface 240 on the fixed valve plate 200 completely covers the connecting groove 310. At this time, the valve core is in the closed state, and even if the valve stem 510 is moved, water will not flow from water passage 1 (210) or water passage 2 (220). In addition, when the valve stem 510 is rotated so that the moving valve plate 300 connects to water passage 1 (210) or water passage 2 (220), the connecting groove 310 first connects to cold water inlet 1 (211) or cold water inlet 2 (221). That is, when the valve core is opened, cold water is discharged first, and the outlet water temperature is adjusted according to actual needs.

[0031] The bottom of the connector 520 has a guide groove 523, and the paddle 530 has a guide strip 531 that slides with the guide groove 523; the protrusion 521 has an arc-shaped protrusion 5211 below it, and the guide strip 531 has a relief groove 532 that matches the arc-shaped protrusion 5211, thereby preventing the paddle 530 from being mistakenly installed on the connector 520.

[0032] The lower end of the base 400 is penetrated by a cold water channel 410, a hot water channel 420, a first water outlet channel 430, and a second water outlet channel 440. The lower end of the base 400 has a positioning foot 470 that mates with a faucet.

[0033] like Figures 12-13As shown, in some embodiments, the lower end of the base 400 has a connecting foot 480, which is penetrated by a cold water channel 410, a hot water channel 420, a first water outlet channel 430, and a second water outlet channel 440, and each of the cold water channel 410, the hot water channel 420, the first water outlet channel 430, and the second water outlet channel 440 is provided with a threaded joint 481.

[0034] The working principle of this invention is as follows: Cold water enters the valve core through the cold water channel 410, and hot water enters the valve core through the hot water channel 420. The cold water channel 410 simultaneously supplies water to cold water inlet 211 and cold water inlet 221, and the hot water channel 420 simultaneously supplies water to hot water inlet 212 and hot water inlet 222. Rotating the valve stem 510 drives the connecting seat 520, the lever 530, and the moving valve plate 300 to rotate simultaneously. When the connecting groove 310 connects to the water passage 210, the connecting groove 310 connects cold water inlet 211 and / or hot water inlet 212 to the outlet 213, and the water can then be discharged sequentially from the outlet 213 and the outlet channel 430.

[0035] When the valve stem 510 is rotated in the opposite direction, the ejector pin 5222 will automatically engage with the positioning groove 131. This vibration of the valve stem 510 will then signal to the user that the control of water circuit 1 210 has ended. After the ejector pin 5222 passes the positioning groove 131, the connecting groove 310 will connect to water circuit 220. That is, the connecting groove 310 connects the cold water inlet 221 and / or the hot water inlet 222 to the outlet 223, and the water can then be discharged from the outlet 223 and the outlet channel 2 440 in sequence. The valve plate 300 can switch the water outlet of water circuit 1 210 and water circuit 2 220 by rotating horizontally; at the same time, by controlling the connection ratio between the connecting groove 310 and the cold water port 1 211 and the hot water port 1 212 through the valve stem 510, the water outlet temperature of water outlet 1 213 can be adjusted; by controlling the connection ratio between the connecting groove 310 and the cold water port 221 and the hot water port 222, the water outlet temperature of water outlet 223 can be adjusted. The water outlet temperature and water flow of the two water circuits are independently controlled and do not interfere with each other. When the valve stem 510 switches the water outlet circuit, the operation direction is opposite.

[0036] Taking water circuit 210 as an example: When the moving valve plate 300 rotates horizontally, the connection area between the cold water inlet 211 and / or the hot water inlet 212 and the outlet 213 remains constant. The valve core only discharges the basic water flow, which is suitable for low-flow water use. The user can drive the moving valve plate 300 to slide by moving the valve rod 510, thereby increasing the connection area between the cold water inlet 211 and / or the hot water inlet 212 and the outlet 213, and thus increasing the water flow of the outlet 213. The water flow control of water circuit 220 is the same as that of water circuit 210.

[0037] In addition, when the moving valve plate 300 rotates horizontally, water circuit 210 is first connected to outlet 213 via cold water port 211, meaning cold water flows out of outlet 213 first. As the moving valve plate 300 continues to increase its rotation amplitude, hot water port 212 can then connect to outlet 213, thereby increasing the outlet water temperature. Similarly, water circuit 220 is also first connected to outlet 223 via cold water port 221. In other words, when the valve core is opened, cold water is discharged first, and the user can then adjust the outlet water temperature according to actual needs.
