A valve core capable of controlling a communication passage and a faucet

Abstract

The application relates to a valve core and a faucet with controllable communication channels, which comprises a swing arm, a rotary connecting piece, a dial, a lower porcelain sheet, an upper porcelain sheet, a front sheet, a shell, a limiting column, a movable piece and a spring. The limiting column is arranged in the shell, the dial is provided with the movable piece, and the spring abuts against the movable piece and the upper porcelain sheet. The movable piece blocks the limiting column, so that the dial cannot move outward in a straight line, and the limiting column abuts against the movable piece to move left and right. The communication groove of the upper porcelain sheet is located at the right upper corner outside the flow guide groove. When the vertical swing arm limiting column is close to the middle position and the left position of the limiting table, the first water inlet hole and the second water inlet hole are disconnected and communicated. When the limiting column is close to the right position of the limiting table, the first water inlet hole and the second water inlet hole are communicated with the communication groove. When the inclined swing arm limiting table right position is close to the limiting column, the limiting column is blocked by the movable piece and cannot directly vertically swing, and the arc-shaped movable piece outer straight surface guides the dial to rotate and move to the middle position of the limiting table. The valve core can independently select the shortest waterway communication channel, and is more energy-saving.

Description

Technical Field

[0001] This invention belongs to the field of faucet technology, specifically relating to a valve core and faucet with controllable communication channels. Background Technology

[0002] The water circulation system of a "zero cold water" water heater typically uses a pre-buried return pipe at the furthest end or an "H-type check valve" to form a water circuit.

[0003] Patent application number 2022102559791 discloses a valve core and a faucet, which connects the water circuit when closed, replacing the "H-type one-way valve".

[0004] The "zero cold water" water heater's water circulation system has multiple water outlets. Regardless of which water outlet is using the water, it circulates from the furthest water outlet and cannot connect to the nearest water outlet. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention provides a valve core with a controllable communication channel. By setting a movable part on the valve core paddle, the movement trajectory of the faucet handle is blocked by the movable part, and the movement trajectory from open to closed can only reach the middle or left position of the limit platform, thus disconnecting the water passages of the first and second water inlets. When closed, rotating the handle toward the right position of the limit platform connects the water passages of the first and second water inlets.

[0006] The technical problem to be solved by this invention is achieved through the following technical solution:

[0007] A valve core for controlling communication channels includes a rocker arm, a rotating connector, a paddle, a lower ceramic plate, an upper ceramic plate, a front plate, a housing, a limiting post, a movable part, and a spring;

[0008] The swing arm is connected to the rotating connector, the rotating connector is connected to the upper end of the outer shell, the front piece is connected to the lower end of the outer shell, the inner side of the front piece is connected to the front of the lower ceramic piece, the upper ceramic piece is attached to the back of the lower ceramic piece, the upper ceramic piece is fixedly connected to the lever, the outer shell is provided with a limiting post, the lever is provided with a movable part, the lever and the upper ceramic piece are moved by the swing arm, and the rotating connector is rotated by the swing arm.

[0009] Preferably, the movable part is provided with a movable part guide surface and an upper spring post, and the outer straight surface of the movable part is set in an arc shape in the direction from the middle position to the right position of the limiting platform.

[0010] Preferably, the movable component blocks the limiting post, preventing the lever from moving outward in a straight line.

[0011] Preferably, the movable component is provided with a movable component guide surface.

[0012] Preferably, the limiting post presses against the guide surface of the movable part, causing the lever to move left and right.

[0013] Preferably, the lever is provided with a limiting hole for the moving part to pass through.

[0014] Preferably, the connecting groove on the lower end face of the upper ceramic tile is located at the upper right corner outside the guide groove.

[0015] Preferably, a lower spring hole is provided on the upper end face of the upper ceramic tile.

[0016] Preferably, the spring abuts against the movable member.

[0017] Preferably, when the valve core swing arm is vertically closed, the left-turning swing arm limiting post of the rotating connector presses against the guide surface of the movable part and moves to the right of the limiting platform. The upper ceramic plate guide groove covers the lower ceramic plate water outlet hole, and the connecting groove simultaneously covers the first water inlet hole and the second water inlet hole.

[0018] A faucet having a valve core with the aforementioned controllable communication channel.

[0019] The beneficial effects of this invention are:

[0020] 1. The valve core of the present invention has a movable part set in the paddle. When the faucet is closed, rotating the handle toward the hot water direction connects the water circuit. It is applied to the water circulation system of a "zero cold water" water heater.

[0021] 2. The valve core of this invention has an independently selectable shortest water path connection channel, which is more energy-efficient;

[0022] 3. When the faucet handle with the valve core of this invention is turned off from hot and cold water circuits when it is turned off, it avoids the water circuit being connected at multiple points due to forgetting to return the handle to its original position, which is in line with user habits.

[0037] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the specific implementation methods, structural features and effects of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0038] To address the limitation of existing faucets that only connect water channels when closed but not disconnect them, this invention provides a valve core and faucet with controllable connection channels. By incorporating a movable component in the valve core's lever, the faucet can disconnect the water channel when the handle is in the cold water or mixed hot and cold water position, and connect the water channel when it is in the hot water position. The faucet's handle movement trajectory from open to closed disconnects the hot and cold water channels, preventing the return of the handle from causing multiple points of connection in the water channel.

[0039] This embodiment provides a valve core that can control the communication channel. The valve core includes a rocker arm 12, a rotating connector 13, a paddle 1, a lower ceramic plate 3, an upper ceramic plate 2, a front plate 10, a housing 11, a limiting post 4, a movable part 7, and a spring 9.

[0040] like Figure 1 The valve core components are positioned as follows: the swing arm 12 is connected to the rotating connector 13, the rotating connector 13 is connected to the upper end of the valve core housing 11, the valve core front plate 10 is connected to the lower end of the valve core housing 11, the inner side of the valve core front plate 10 is connected to the front of the lower ceramic plate 3, the upper ceramic plate 2 is attached to the back of the lower ceramic plate 3, the upper ceramic plate 2 is fixedly connected to the lever 1, the lever 1 and the upper ceramic plate 2 are moved by the lower end of the swing arm 12, the rotating connector 13 is rotated by the swing arm 12, the swing arm 12 drives the lever 1 and the upper ceramic plate 2 to move inside the housing 11, the lever 1 is provided with a movable part 7, and the spring 9 pushes the upper ceramic plate 2.

[0041] like Figure 2 As shown, the lower end face of the upper ceramic plate 2 is provided with a guide groove 20 and a connecting groove 21, with the connecting groove 21 located at the upper right corner outside the guide groove 20.

[0042] like Figure 3 As shown, a lower spring hole 17 is provided on the upper end face of the upper ceramic tile 2. Figure 4 As shown, a limiting post 4 is provided inside the outer shell 11, and the inner surface 19 of the limiting post is straight.

[0043] like Figure 5 As shown, the movable part 7 is provided with a movable part guide surface 16, a movable part top surface 25, an upper spring post 26, a movable part outer straight surface 15, and a spring 9 for the movable part 7.

[0044] The lower end of the spring abuts against the lower spring hole of the ceramic plate, and the upper end abuts against the upper spring post of the movable part. The movable part abuts against the end face of the lever through the limiting platform hole and the top surface of the movable part, thus limiting the rising height of the movable part.

[0045] like Figure 6 As shown, the lever 1 is provided with a limiting platform 5 and a lever hole 26. The limiting platform 5 has a flange with a center position 6, a right position 8, and a lever end face 14, with a limiting platform hole 18 provided at the center and right positions.

[0046] The movable part 7 passes through the limiting platform hole 18. The top surface 25 of the movable part is pressed against the end face 14 of the lever by the elastic force of the spring 9. The outer straight surface 15 of the movable part is set in an arc shape in the direction from the middle position 6 to the right position 8 of the limiting platform 5. The guide surface 16 of the movable part is set in an inclined surface in the direction from the middle position 6 to the right position 8 of the limiting platform 5.

[0047] like Figure 7 As shown, the inclined pressure swing arm 12 (when in the open state) is located to the left. The diagram shows the positional relationship between the faucet handle in the hot water direction, the upper ceramic plate 2, the lower ceramic plate 3, the limit post 4, and the movable part 7.

[0048] The inclined pressure swing arm (when in the open state) is in the positive direction, and the upper ceramic plate guide groove simultaneously covers the lower ceramic plate water outlet, the first water inlet, and the second water inlet. The connecting groove is located outside the first water inlet.

[0049] When the inclined pressure swing arm (in the open state) turns to the left, the inner straight surface of the limit column moves to the right of the limit platform corresponding to the outer straight surface of the moving part; the upper ceramic plate guide groove covers the lower ceramic plate water outlet and the first water inlet, and the connecting groove is located outside the first water inlet and the second water inlet.

[0050] When the inclined swing arm (in the open state) is located to the left, the right side of the limiting platform is close to the limiting post of the outer shell. The inner straight surface of the limiting post is blocked by the outer straight surface of the moving part and cannot directly press down the swing arm. The lever cannot move directly outward. Guided by the outer straight surface of the arc-shaped moving part and driven by the rotating connecting part, the lever rotates so that the limiting post avoids the right side of the limiting platform and slides to the middle position of the limiting platform.

[0051] That is, when the faucet is turned off, the handle can only return to the middle or left position, and the first and second water inlets are disconnected.

[0052] The outer straight surface 15 of the moving part blocks the limit post, and the inner straight surface 19 prevents the vertical swing arm 12 from directly reaching the right position 8 of the limit platform 5. For example... Figure 6 The outer straight surface 15 of the movable part is set in an arc shape from the middle position 6 to the right position 8 of the limiting platform 5. Guided by the arc-shaped outer straight surface 15 of the movable part, the faucet handle slides to the middle position. When the faucet is turned off, the connection between the hot and cold water circuits is disconnected, avoiding the problem of multiple water circuit connections caused by forgetting to return the handle to its original position, which conforms to user habits.

[0053] like Figure 8 The diagram shows the positional relationship of the swing arm 12, rotating connector 13, front piece 10, paddle 1, upper ceramic piece 2, limit post 4, and movable part 7.

[0054] When the vertical valve core swing arm 12 (in the closed state) rotates the faucet handle rotating connector 13 to the left, the limit post 4 presses down the movable part 7 to the right position 8 of the limit platform 5. The faucet is in the hot water closed state.

[0055] The vertical valve core swing arm (in the closed state) has its limiting platform in the middle position close to the outer shell limiting post. The upper ceramic guide groove only covers the lower ceramic outlet hole, and the connecting groove is located on one side of the first inlet hole.

[0056] When the vertical valve core swing arm is in the closed state, the rotating connector rotates the swing arm to the left, the limit post presses against the guide surface of the movable part, and the height of the movable part is reduced and it moves to the right of the limit platform; the upper ceramic plate guide groove only covers the lower ceramic plate water outlet hole, and the connecting groove covers the first water inlet hole and the second water inlet hole at the same time.

[0057] like Figure 9 As shown in the diagram, the upper and lower ceramic tiles are positioned in the closed state: the lower end face of the upper ceramic tile 2 is attached to the back of the lower ceramic tile 3, the guide groove 20 covers the water outlet 22, and the connecting groove 21 covers both the first water inlet 23 and the second water inlet 24. When the faucet is closed, the handle faces the direction of hot water to connect the water path.

[0058] like Figure 10As shown, the vertical valve core swing arm 12 (in the closed state) rotates the faucet handle. Since the movable part guide surface 16 is set as an inclined surface in the direction from the middle position 6 to the right position 8 of the limit platform 5, the limit column 4 slides and pushes the movable part guide surface 16 in the motion state diagram.

[0059] like Figure 11 As shown, when faucet 27 is closed, rotating the handle towards the hot water position connects the hot and cold water channels at this water point. When faucet 28 is closed, rotating the handle towards the furthest point disconnects the water channel. The "zero cold water" circulation system circulates in a closed loop from faucet 27.

[0060] like Figure 12 As shown, this embodiment provides a paddle movable part 7 and a spring 9 with a lateral abutment structure. This movable part 7 does not have a guide surface, and the limiting post 4 slides and pushes the movable part 7 to move sideways.

[0061] The method for connecting the upper and lower ceramic tiles, the guide groove, the water outlet, the first water inlet, and the second water inlet in this invention to cover the positions is prior art and will not be described here.

[0062] This invention provides a faucet with a valve core that controls the connection channel. When the faucet is turned on or off, the handle (movement trajectory) disconnects the hot and cold water circuits, preventing multiple water circuit connections caused by forgetting to return the handle to its original position, and conforming to user habits. When the faucet is closed, the handle is facing the hot water direction to connect the water circuit.

[0063] The above description also allows for various modifications, such as setting the limiting post to an active state, setting the movable part to a fixed state, connecting the movable part to a paddle or to a ceramic plate, changing the position of the guide surface, and interchangeable left and right positions as well as hot and cold water inlet holes. Any modifications, variations, or changes to the equivalent principles made by those skilled in the art using the same functionality as this invention are within the scope of this invention's claims, and are not limited to those disclosed in the embodiments. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of this invention, and all such modifications or substitutions should be considered within the protection scope of this invention.
