Technical Field

[0001] The utility model relates to the technical field of electric water faucets, in particular to a touch-controlled electric water faucet. Background Art

[0002] Electric water faucets are widely used in home kitchens and public washrooms because of their instant heating function. Based on the need for the liquid flow cut-off function, a control valve assembly is usually provided to realize the manual control of the liquid flow cut-off function. At the same time, for the convenience and intelligence of use, it is also considered to set an on-off electrical device inside the electric water faucet to control the liquid flow cut-off, and design a trigger component on the electric water faucet to trigger the working state of the on-off electrical device. The conventional method is to design a far-infrared sensor on the body or faucet of the electric water faucet, and trigger the action by approaching the user. However, there is a situation that the user only approaches or passes by and performs other actions. For example, in the use of a home kitchen, when the user only performs other actions near the faucet, the electric water faucet using a far-infrared sensor will also misjudge that water is needed and automatically perform the water flow conduction action by mistake, so the signal acquisition has the problem of inaccuracy.

[0034] The touch sensing sheet 4 is fixedly mounted in the main body 1 and contacts the metal material portion of the water outlet pipe 3;

[0035] In addition, a control circuit board 8 electrically connected to the on-off control device 2 and the touch sensing sheet 4 is arranged in the main body 1. The touch sensing sheet 4 is located above the control circuit board 8 and can trigger the touch sensing sheet 4 when the user touches the trigger area, thereby changing the working state of the on-off control device 2 through the control circuit board 8.

[0036] Based on the above technical solution, the touch-controlled electric water faucet includes a main body 1, an on-off control device 2, a water outlet pipe 3, a touch-sensitive sheet 4, and a control circuit board 8. The main body 1 is provided with a water storage and heating chamber 5, a water inlet channel 6, and a water outlet channel 7. The outer surface of the main body is provided with a trigger area made of a metal material. The touch-sensitive sheet 4 is in contact with or electrically connected to the trigger area. When a user touches the trigger area, the on-off control device 2 can be triggered to change the purpose of liquid flow interruption in the main body 1. The faucet is more intelligent and convenient, and the liquid flow interruption control is more reasonable and reliable, avoiding the misjudgment of conducting the liquid flow based on the user passing by or approaching, for example, in a solution using a far-infrared component as a trigger component.

Furthermore, the water outlet pipe 3 is made of metal material as a whole, that is, the user can trigger the sensing contact sheet by touching any position of the water outlet pipe 3. However, it is obvious that it is also possible to consider setting a metal ring on the outer wall of one end of the water outlet pipe 3 and extending in the direction of the other end to form a contact area, which can also be changed to a structure in which the sensing contact sheet can be triggered only when the contact area is touched for the above technical purpose, and is not limited to this.

[0041] As a further preferred embodiment, Figure 2 and Figure 3 As shown in the figure, the main body 1 includes an inner tank 18, a water inlet assembly 9 and a water outlet assembly 10 mounted on the upper and lower ends of the inner tank 18, and a water storage and heating chamber 5 is formed in the inner tank 18, a water inlet channel 6 is formed in the water inlet assembly 9, and a water outlet channel 7 is formed in the water outlet assembly 10. The on-off control device 2 is mounted on the water inlet assembly 9 and is used to control the on-off relationship between the water inlet channel 6 and the water storage and heating chamber 5. However, it is obvious that it can also be considered to be arranged in the water outlet assembly 10, or one is set in the water inlet assembly 9 and the water outlet assembly 10 respectively, and it is not limited to this. Furthermore, the on-off control device 2 is a bistable solenoid valve. In specific applications, as a component for on-off control, it can also be considered to be designed as a motor + rack + blocking block, etc., and it is not limited to this.

[0042] In a preferred embodiment, the water outlet assembly 10 includes a water tank cover 11, and a water through hole 12 running longitudinally through the water tank cover 11 is formed in the water tank cover 11, and the water through hole 12 serves as a part of the water outlet channel 7. The upper end of the water tank cover 11 also forms an upper open mounting groove around the water through hole 12, and the lower end of the water outlet pipe 3 can be rotatably assembled in the mounting groove. Furthermore, an open groove 13 connected to the mounting groove is formed on the side wall of the water tank cover 11, and the touch sensor sheet 4 at least partially passes through the open groove 13 from the outside to the inside and abuts against the outer wall of the water outlet pipe 3. In addition, the water outlet pipe 3 can also be designed as a fixed and non-rotatable structure or a structure that is limited to a certain angle of rotation, but is not limited to this. Further, in combination with Figure 4 As shown, the main part of the touch sensing sheet 4 is in a horizontal "V" shape in the cross-sectional direction, and the touch sensing sheet 4 is elastic and the protruding part abuts against the outer wall of the water outlet pipe 3.

That is, this solution can also use the casing 19 as a part of the triggering component, rather than being limited to the water outlet pipe, so that the sensing method is more diversified. Specifically, the touch sensing sheet 4 can be connected to the metal material portion of the casing 19 via screws or wires, or directly contact the casing 19 after the touch sensing sheet 4 is fixed to the water tank cover 11, so as to achieve the above purpose, so that the user can also play this function by touching the casing 19. At the same time, similar to the above, the casing 19 can be made of metal material as a whole, or metal inserts can be additionally arranged on the casing 19 and extended to the periphery of the casing 19 to form a triggering area.

In consideration of simple wiring, the touch sensing connection line 14 is electrically connected to the control circuit board 8 via the wire board 15 of the digital display assembly 20. At the same time, the control circuit board 8 assembly is also connected to a power line extending outward from the housing 19, which is a common structure in the field of electric water faucets or a structure that can be ignored and omitted in this scheme, so it is omitted in this embodiment, but it should not be the reason for its unimplementability. In addition, the electric water faucet with a vertical structure adopted in this embodiment, and the water outlet assembly 10 is at the bottom and the water inlet assembly 9 is at the top, but it is also applicable to the electric water faucet with the inner tank 18 arranged horizontally, and the water inlet and outlet directions can also be changed based on needs. Whether the water outlet pipe 3 adopts a curved pipe or a straight pipe is determined based on its water outlet direction, and is not limited to this. The control circuit board 8 is also preset with a delay switch, for example, after a certain period of time after the user's touch triggers the touch sensor sheet 4 and the electromagnetic valve to operate, the control battery valve is switched to a closed state again to block the water inlet channel 6 and the water storage heating chamber 5, or after the control valve assembly 16 is switched to a closed state, the electromagnetic valve is switched to a closed state, which can be determined based on the user's choice and usage requirements. The above-mentioned metal material is preferably stainless steel, but it can also be, for example, copper, iron, aluminum or other alloys.

[0046] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive.
