Description

Technical Field

[0001] The utility model relates to the technical field of waterway control, and particularly relates to a dual waterway control structure. Background Art

[0002] With the improvement of living standards, it is difficult for traditional sanitary products to meet people's needs in terms of functions, styles and qualities. Therefore, there are an endless stream of faucets with diverse styles and intelligent functions on the market. For example, electronic sanitary products such as induction kitchen faucets, touch kitchen faucets, digital display constant temperature faucets, and digital display showers have been gradually popularized in the market.

[0003] When consumers choose electronic sanitary products, they usually focus on their stability during use. The core of electronic sanitary products is the solenoid valve, which is used to control the opening and closing of the waterway. When there is no power or an electronic failure occurs, the solenoid valve cannot be used normally, resulting in the inability of the electronic sanitary product to discharge water and affecting the user experience.

[0004] Therefore, how to ensure the normal water discharge of electronic sanitary products when the solenoid valve cannot be used normally is the problem to be solved in this case. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a dual waterway control structure to solve the above technical problems and enable normal water discharge of the waterway when the solenoid valve cannot be used normally.

[0006] To achieve the above object, the solution of the utility model is: a dual waterway control structure, including a valve seat, a solenoid valve diaphragm, a driving rod and a solenoid valve driving member;

[0007] An inlet channel and an outlet channel are formed in the valve seat. The inlet channel and the outlet channel are communicated through a water passing port in the valve seat. One side of the solenoid valve diaphragm faces the water passing port and is used for pressing and blocking the water passing port. The other side separates a back pressure chamber in the valve seat. The back pressure chamber is communicated with the inlet channel. A pressure relief channel is also provided, which communicates the back pressure chamber with the outlet channel. The solenoid valve driving member opens or blocks the pressure relief channel. When the pressure relief channel is blocked, water flows from the inlet channel into the back pressure chamber to form back pressure, and the water pressure pushes against the solenoid valve diaphragm from the back pressure chamber to block the water passing port. When the pressure relief channel is opened, the back pressure chamber is communicated with the water passing port, and the water pressure pushes against the solenoid valve diaphragm from the inlet channel to open the water passing port. The driving rod is installed on the valve seat, and one end extends into the side of the solenoid valve diaphragm facing away from the back pressure chamber and is used to push against the solenoid valve diaphragm to open the water passing port.

[0008] Further, the solenoid valve diaphragm is an elastic pad that can elastically deform. When it deforms in the direction away from the water passing port, the water passing port is opened. When it deforms in the direction towards the water passing port, the water passing port is closed.

[0009] Furthermore, a plug is formed on the side of the solenoid valve diaphragm facing the water outlet, and the plug is a conical structure.

[0010] Furthermore, an elastic member is arranged in the back pressure chamber, one end of the elastic member abuts against the diaphragm of the solenoid valve, and the other end of the elastic member abuts against the inner side wall of the back pressure chamber.

[0011] Furthermore, the elastic member is a conical spring.

[0012] Furthermore, it also includes a water passing part, which is arranged in the valve seat and forms the water passing port. The water inlet channel surrounds the outer periphery of the water passing port and leads to one end of the water passing port, and the other end of the water passing port is connected to the water outlet channel.

[0013] Furthermore, a mounting channel for inserting a driving rod is provided on the valve seat. The mounting channel faces the solenoid valve diaphragm and is located on the side of the solenoid valve diaphragm away from the back pressure chamber. The driving rod and the mounting channel are connected by threads and are sealed in the mounting channel. The inner end of the driving rod is against the solenoid valve diaphragm, and a knob is fixed to the outer end of the driving rod. The driving knob rotates, driving the driving rod to rotate relative to the mounting channel so as to move closer to or away from the solenoid valve diaphragm.

[0014] Furthermore, the solenoid valve driving component includes a solenoid valve body and a piston. The solenoid valve is electrically connected to an external power supply. When the solenoid valve is in a non-working state, the piston blocks the pressure relief channel. When the solenoid valve is in a working state, the piston is driven to move away from the pressure relief channel to open the pressure relief channel.

[0015] After adopting the above scheme, the beneficial effect of the utility model is that: by setting two control modes for opening the waterway on the same waterway, one is the solenoid valve control, and the other is the mechanical control mode of the driving rod, in one of which, the solenoid valve driving member can open the pressure relief channel, relieve the pressure on the back pressure chamber, so that the water pressure pushes the solenoid valve diaphragm from the side of the water inlet channel, opens the water outlet, connects the water inlet channel with the water outlet channel, and realizes water discharge, and when the solenoid valve driving member closes the pressure relief channel, back pressure is formed in the back pressure chamber, the solenoid valve diaphragm blocks the water outlet, isolates the water inlet channel from the water outlet channel, and disconnects the waterway; in the second of which, by setting a driving rod, the driving rod is installed on the valve seat and extends into one side of the solenoid valve diaphragm, and pushes the solenoid valve diaphragm from the side facing away from the back pressure chamber to open the water outlet and realize water discharge; the two control modes are independent of each other and can be switched with each other. When the solenoid valve is powered off, the water outlet can be opened by the driving rod to realize water discharge, and the structure is more compact. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0026] The following will make a detailed description of the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0027] In the claims, description and above-mentioned drawings of the present utility model, unless otherwise clearly defined, for orientation terms, such as using terms "center", "horizontal", "longitudinal", "level", "vertical", "top", "bottom", "inner", "outer", "upper", "lower", "front", "rear", "left", "right", "clockwise", "counterclockwise", etc. to indicate orientation or position relationship is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as limiting the specific protection scope of the present utility model either.

[0028] As Figures 1 to 8 shown, the present utility model provides a water path dual control structure, with a focus on combining Figures 1 to 3As shown in the figure, it includes a valve seat 1, a solenoid valve diaphragm 2, a drive rod 3 and a solenoid valve driver 4; an inlet channel 5 and an outlet channel 6 are formed in the valve seat 1, and the inlet channel 5 and the outlet channel 6 are communicated through a water passing port 7 in the valve seat 1. One side of the solenoid valve diaphragm 2 faces the water passing port 7 and is used to press and seal the water passing port 7. The other side separates a back pressure chamber 8 in the valve seat 1. The back pressure chamber 8 is communicated with the inlet channel 5. Specifically, a first through hole 22 is provided on the solenoid valve diaphragm 2, and the first through hole 22 communicates the back pressure chamber 8 with the inlet channel 5 (as Figure 8 shown), a pressure relief channel 9 is also provided in the back pressure chamber 8, and the pressure relief channel 9 communicates the back pressure chamber 8 to the outlet channel 6. The solenoid valve driver 4 opens or blocks the pressure relief channel 9. When the pressure relief channel 9 is blocked, as water continuously flows in, the water flows from the inlet channel 5 into the back pressure chamber 8. After the water enters the back pressure chamber 8, a back pressure is formed in the back pressure chamber 8, and the water pressure pushes against the solenoid valve diaphragm 2 from the back pressure chamber 8, so that the solenoid valve diaphragm 2 seals the water passing port 7. When the pressure relief channel 9 is opened, the back pressure chamber 8 is communicated with the water passing port 7, that is, the back pressure chamber 8 is simultaneously communicated with the outlet channel 6, and the pressure in the back pressure chamber 8 is released, so that the pressure in the inlet channel 5 is higher than the pressure in the back pressure chamber 8, and the water pressure pushes against the solenoid valve diaphragm 2 from the inlet channel 5, opening the water passing port 7, and communicating the inlet channel 5 and the outlet channel 6. The drive rod 3 is installed on the valve seat 1, and one end extends into the side of the solenoid valve diaphragm 2 facing away from the back pressure chamber 8 and is used to push against the solenoid valve diaphragm 2 to open the water passing port 7. It is possible to push against the solenoid valve diaphragm 2 through the drive rod 3 to open the water passing port 7 and communicate the inlet channel 5 and the outlet channel 6 when the solenoid valve driver 4 does not work.

[0029] Focusing on Figure 2 and Figures 5 - 6 shown, a plug 21 is formed on the side of the solenoid valve diaphragm 2 facing the water passing port 7. The plug 21 is a conical structure, and the conical structure is provided to facilitate guiding the plug 21 to be inserted into the water passing port 7 and can provide a sealing effect.

[0030] In this specific embodiment, the solenoid valve diaphragm 2 is an elastic pad and can elastically deform. When it deforms in the direction away from the water passing port 7, the water passing port 7 is opened. When it deforms in the direction of the water passing port 7, the water passing port 7 is closed. Of course, in other embodiments, the solenoid valve diaphragm 2 can also be a piston, which is slidably arranged in the valve seat 1 and can approach or move away from the water passing port 7. When approaching the water passing port 7, it seals the water passing port 7, and when moving away from the water passing port 7, it opens the water passing port 7.

[0031] Focusing on Figure 6As shown in the figure, an elastic member 10 is disposed in the back pressure chamber 8. One end of the elastic member 10 abuts against the solenoid valve diaphragm 2, and the other end abuts against the inner side wall of the back pressure chamber 8, which can further block the solenoid valve diaphragm 2 on the water passing port 7 and restrict the solenoid valve diaphragm 2 from moving away from the water passing port 7. The elastic member 10 is a conical spring. Specifically, the conical end abuts against the solenoid valve diaphragm 2, and the stability is better.

[0032] Focusing on Figure 5 As shown in the figure, the solenoid valve driving member 4 includes a solenoid valve body 13 and a piston 18. The solenoid valve body 13 is electrically connected to an external power supply. When the solenoid valve body 13 is in a non-operating state, the piston 18 blocks the pressure relief passage 9. In the operating state, the piston 18 is driven to move away from the pressure relief passage 9 to open the pressure relief passage 9. Specifically, one end of the piston 18 facing the pressure relief passage 9 is a sealing head for sealing the pressure relief passage 9, and the end facing away from the pressure relief passage 9 is a moving iron core. After the solenoid valve body 13 is energized, an electromagnetic force is generated to attract the moving iron core. This is the prior art and will not be specifically described here. After the moving iron core is lifted, it can drive the sealing head to move away from the pressure relief passage 9, thereby opening the pressure relief passage 9.

[0033] Focusing on Figure 7 and Figure 8 As shown in the figure, it further includes a water passing member 11. The water passing member 11 is disposed in the valve seat 1. The water passing member 11 forms the water passing port 7. A plurality of water passing through holes 14 are arranged in an array around the outer periphery of the water inlet 7. When the water passing member 11 is installed in the valve seat 1, the water inlet passage 5 can be communicated with the water passing through holes 14, and then surround the outer periphery of the water passing port 7 and conduct to one end of the water passing port 7. The water flow can pass through the water passing through holes 14 from the water inlet passage 5 and reach below the solenoid valve diaphragm 2. When the solenoid valve diaphragm 2 opens the water passing port 7, it flows into the water passing port 7. The other end of the water passing port 7 is communicated with the water outlet passage 6, so that the water flow entering the water passing port 7 flows out from the water outlet passage 6. Figure 7 The arrow in Figure 8 indicates the water flow direction, and the arrow in

[0034] Focusing on Figures 5 - 6 and Figure 8As shown, it also includes a mounting seat 15, which is mounted on the valve seat 1 and is located on the side of the solenoid valve diaphragm 2 away from the water outlet 7. The back pressure chamber 8 is formed between the mounting seat 15 and the solenoid valve diaphragm 2. The solenoid valve driving member 4 is detachably mounted on the mounting seat 15. The mounting seat 15 is formed with a pressure relief hole 16 on the side facing the solenoid valve driving member 4. The piston 18 is directly opposite to the pressure relief hole 16 to block the pressure relief hole 16. A connecting through hole 17 is provided on the water passing member 11. The connecting through hole 17 connects the water outlet channel 6 with the pressure relief channel 9. The mounting seat 15 is provided with a plurality of second through holes 19 on the top wall of the back pressure chamber 8. The plurality of second through holes 19 are arranged around the outer periphery of the pressure relief hole 16 and pass through the back pressure chamber 8. When the piston 18 opens the pressure relief hole 16, the back pressure chamber 8 is connected with the pressure relief hole 16 through the second through hole 19, and can then be connected with the water outlet 7 through the pressure relief channel 9 and the connecting through hole 17.

[0035] Focus on combination Figure 2 and Figure 6 As shown, the valve seat 1 is provided with a mounting channel 12 for inserting the drive rod 3, the mounting channel 12 is opposite to the solenoid valve diaphragm 2, and is located on the side of the solenoid valve diaphragm 2 away from the back pressure chamber 8. The drive rod 3 is connected to the mounting channel 12 through a threaded connection and is sealed in the mounting channel 12. Specifically, the outer periphery of the drive rod 3 is provided with an external thread 32, and the mounting channel 12 is provided with an internal thread 121. A water seal is provided between the side of the external thread 32 of the drive rod 3 close to the solenoid valve diaphragm 2 and the mounting channel 12. The inner end of the drive rod 3 is against the solenoid valve diaphragm 2, and a knob 31 is fixed to the outer end of the drive rod 3. The drive knob 31 is rotated to drive the drive rod 3 to rotate relative to the mounting channel 12. A drive groove 33 is provided on the knob 31. The drive groove 33 can be a straight groove or a cross groove, and a bolt driver or other tools can be inserted to drive the knob 31 to rotate.
