Description

Technical Field

[0001] The present invention relates to the technical field of intelligent bathrooms, in particular to an induction control handle, a combination device of the induction control handle and an electric control valve core, and an induction faucet. Background Art

[0002] The structure of the existing common faucet is as follows Figures 1-2 As shown, it includes a common faucet body 1', a mechanical ceramic valve core 2', a common handle 3', a decorative cover 4', a set screw 5', a flange 6' and a buckle cap 7'. The water outlet control of the common faucet adopts a mechanical ceramic valve core 2', which is installed in the cavity of the common faucet body 1', and the common handle 3' is connected to the valve stem of the mechanical ceramic valve core 2'. The operation mode is to manually lift and rotate the handle to realize the on-off of the water flow, the flow rate adjustment, and the mixing ratio adjustment of hot and cold water.

[0003] With the advancement of technology and the improvement of people's requirements for hygiene, induction-controlled faucets have gradually entered people's lives and partially replaced ordinary faucets. However, the processing of induction faucets and their accessories is much more complicated than that of ordinary faucets. The existing structures of induction faucets are mainly the following two types:

[0004] 1. Install the induction element on the faucet body and set a separate electric control box at the lower end of the faucet, such as the structure of patent CN209781740U and patent CN203248766U. This structure requires the electric control box to be installed under the basin. If the electric control box fails, it is necessary to disassemble many parts under the basin, which is troublesome to repair.

[0005] 2. Installing sensing elements and electronic control devices in the faucet body cavity, such as the structure of patent CN105864492B. The body cavity of this structure requires a large space to install the electronic control device, and if the electronic control device fails, the faucet needs to be disassembled for repair.

[0006] Since the above two induction faucet structures are completely different from the internal structures of existing ordinary faucets and cannot be compatible, if an ordinary faucet is to be replaced with an induction faucet, the original ordinary faucet needs to be discarded and the entire faucet needs to be replaced with an induction faucet, which is time-consuming and labor-intensive and also causes a huge waste of resources.

By designing the water inlet of the main body sleeve 3, a valve core structure of a flow regulating type and a cold and hot mixed temperature regulating type can be designed. The following is an explanation of the two valve core structures.

[0092] 1. Electric control valve core for flow adjustment

[0093] like Figures 15 to 22 As shown, the flow regulating type electric control valve core includes a pulse valve, a water distribution turntable 3, a body sleeve 3 and several sealing rings.

[0094] The pulse valve uses a bistable pulse valve 1, and its structure is as follows Fig.15 The bistable pulse valve 1 comprises: a housing 11, a coil core assembly 12, a moving iron core 13, a return spring 14, a plug 15, an upper valve seat 16, a rubber membrane 17, a lower valve seat 18 and an anti-blocking needle spring 19.

[0095] Combination Fig.16 As shown, the shell 11 is hollow inside and has a smooth inner wall.

One end of the pressure relief column 161 corresponds to the position of the plug 15, and the plug 15 blocks the pressure relief hole 162 or separates from the pressure relief hole 162 under the action of the moving iron core 13. The lower valve seat 18 is clamped with the upper valve seat 16, and the lower valve seat 18 and the upper valve seat are sealed and arranged in the shell 11. The edge of the lower valve seat 18 is provided with a valve body water inlet 181, a water outlet column 182 is provided in the middle of the lower valve seat 18, a valve body water outlet 183 is provided in the middle of the water outlet column 182, and a rib 184 is provided at the end of the lower valve seat 18. The rubber membrane 17 is provided between the upper valve seat 16 and the lower valve seat 18, and a through hole 171 and a pressure-increasing hole 172 are provided on the rubber membrane 17. The pressure relief column 161 is inserted into the through hole 171 to connect the pressure relief hole 162 with the valve body water outlet 183. The anti-blocking needle spring 19 is installed between the rubber membrane 17 and the upper valve seat 16.

[0096] The water distribution turntable 2 is provided with a water distribution port 21 and a turntable water outlet 22. Fig.17 As shown, the inner wall of the water-dividing turntable 2 is provided with two positioning ribs 23 cooperating with the ribs 184, and a positioning boss 24 is provided on the turntable water outlet 22 of the water-dividing turntable 2. After the ribs 184 of the lower valve seat 18 are inserted into the two positioning ribs 23 of the water-dividing turntable 2, the water-dividing turntable 2 and the bistable pulse valve are fixed and do not rotate relative to each other. The water-dividing port is connected with the water inlet of the valve body. A second sealing groove 185 is provided at the end of the water outlet column 182 of the lower valve seat 18, and a second sealing ring 42 is installed in the second sealing groove 185. The water outlet column 182 and the second sealing ring 42 are inserted into the positioning boss 24 to realize the sealed communication between the turntable water outlet 22 and the valve body water outlet 183.

[0097] The outer wall of the shell 11 is provided with a first sealing groove 111, and a first sealing ring 41 is installed in the first sealing groove 111. The body sleeve 3 is sleeved on the outside of the water distribution turntable 2 and the bistable pulse valve 1, and the inner wall of the body sleeve 3 is sealed and connected with the first sealing ring 41.

[0098] The outer wall of the body sleeve 3 is provided with an outer wall sealing groove 33, and an outer wall sealing ring 43 is installed in the outer wall sealing groove 33. The outer periphery of the end faces of the body water inlet 31 and the body water outlet 32 ​​is provided with an end face sealing groove 34, and an end face sealing ring 44 is installed in the end face sealing groove 34. The provision of the outer wall sealing ring 43 and the end face sealing ring 44 facilitates the valve core of the present invention to be integrally installed in the inner wall cavity of the induction faucet body for sealing and use.

[0099] like Fig. 20 As shown, a body water inlet 31 and a body water outlet 32 ​​are arranged on the body sleeve 3 of the flow regulating electric control valve core.

[0100] The shell 11 is provided with a snap-in groove 112 for cooperating with an external part, and the end of the body shell 3 is provided with a protrusion 35 for cooperating with an external part.

[0101] The flow-adjustable electric control valve core can control the on / off of the water source and adjust the flow rate.

[0102] The principle of controlling the water source on and off is as follows: the docking terminal 121 is electrically connected to the output terminal 62 of the induction control handle. When the power is not turned on, Fig.18 As shown, the moving iron core 13 and the plug 15 are located at the bottom, and the plug 15 blocks the pressure relief hole 162. At this time, the water flow direction is as shown by the arrow in the figure, and can only flow under the rubber membrane 17 and cannot enter the valve body water outlet 183. At this time, the water flow is disconnected. Fig.19 As shown, the external control circuit gives a pulse current to the coil core group 12 through the docking terminal 121. The coil is energized to generate a magnetic field, which makes the moving iron core 13 move upward. The moving iron core 13 drives the plug 15 to disengage from the pressure relief hole 162. The pressure makes the rubber membrane 17 move upward. At this time, the water flow direction is shown by the arrow in the figure. The water flows from the main body water inlet 31 through the water diversion port 21 and then enters the valve body water inlet 181, and flows out through the valve body water outlet 183, through the turntable water outlet 22, and then flows out from the main body water outlet 32.

[0103] The principle of adjusting the flow rate is as follows: rotate the bistable pulse valve 1, so that the water distribution turntable 2 fixed to it and the body sleeve 3 fixed on the external part rotate relative to each other. Fig.21 As shown, when the water diversion port 21 and the water inlet 31 of the main body completely overlap, the water flow rate is the largest. During the rotation process, the overlapping portion of the water diversion port 21 and the water inlet 31 of the main body becomes smaller, thereby reducing the water flow rate. Fig. 22 shown.

[0105] like Figures 23 to 25As shown, the difference between the electric control valve core and the electric control valve core of the flow regulating type is that two body water inlets 31 are provided on the body sleeve 3, namely the cold water inlet 311 and the hot water inlet 312. The electric control valve core 9 can realize the function of controlling the on and off of the water source and adjusting the water temperature. The principle of controlling the on and off of the water source is the same as that of the electric control valve core of the flow regulating type.

[0106] The principle of controlling the water temperature is: connect the cold water inlet 311 to the cold water pipe, and connect the hot water inlet 312 to the hot water pipe. Rotate the bistable pulse valve 1, so that the water distribution disc 2 fixed to it and the body sleeve 3 fixed on the external part rotate relative to each other. Fig.24 As shown, when the water outlet 21 completely overlaps with the cold water inlet 311 and the hot water inlet 312, the cold water inlet amount is the same as the hot water inlet amount, and the water temperature is moderate. Fig.25 As shown, during the process of the water-dividing rotating disk 2 rotating toward the cold water inlet 311, the overlapping portion of the water-dividing rotating disk 21 and the hot water inlet 312 becomes smaller, the hot water inlet amount decreases, and the water temperature is adjusted lower. Similarly, during the process of the water-dividing rotating disk 2 rotating toward the hot water inlet 312, the overlapping portion of the water-dividing rotating disk 21 and the cold water inlet 311 becomes smaller, the cold water inlet amount decreases, and the water temperature is adjusted higher.
