Description

Technical Field

[0001] The utility model relates to the technical field of electric water faucets, in particular to an assembly structure of a touch sensing component. Background Art

[0002] Electric water faucets are widely used in home kitchens and public washrooms because of their instant heating function. Based on the needs of liquid flow interruption function, internal heating, or temperature and time display on the digital display screen, a trigger component is usually set to trigger such functions. Common trigger components usually use far-infrared sensors to trigger the opening and closing of the above functions based on the user's approach. However, there is a situation where the user is only approaching or passing by and performing other actions. For example, in the use of home kitchens, when the user is only near the faucet and doing other actions, the electric water faucet using far-infrared sensors will also misjudge that water is needed and automatically perform water flow conduction or heating and other actions by mistake, so the signal collection is not accurate enough. Utility Model Content

An open groove connected to the mounting groove is also formed on the side wall of the water tank cover, and the touch sensor sheet at least partially passes through the open groove from the outside to the inside and abuts against the outer wall of the water outlet elbow.

[0008] Preferably, the main body of the touch sensor sheet is in a transverse "V" shape in the cross-sectional direction, the touch sensor sheet is elastic and the protruding portion abuts against the outer wall of the water outlet elbow.

[0021] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the following embodiments are combined with the accompanying drawings to specifically describe the utility model. The radial inward direction along the inner tank of the electric water faucet is defined as the direction from outside to inside in this embodiment.

[0022] See also Figure 1 system Figure 6 As shown in , the touch sensing component assembly structure provided in this embodiment is suitable for configuring the touch sensing component in an electric water faucet, the electric water faucet comprises a water tank cover 1 which is longitudinally penetrated and has a water through hole 10, and a water outlet elbow 2 which is rotatably configured on the water tank cover 1 at the lower end, and the water outlet elbow 2 is at least partially made of metal material; wherein,

[0023] The touch sensing component includes a touch sensing sheet 3 and an electrical connection 4 electrically connected to the touch sensing sheet 3. The touch sensing sheet 3 is fixedly mounted on the water tank cover 1 and contacts the metal material portion of the water outlet elbow 2. The end of the electrical connection 4 facing away from the touch sensing sheet 3 extends into the electric water faucet and is electrically connected to the control circuit board 5 in the electric water faucet.

[0024] Based on the above, the touch sensing component assembly structure is used to configure the touch sensing component in the electric water faucet. The electric water faucet includes a water tank cover 1, a water outlet elbow 2, and a control circuit board 5. The touch sensing component includes a touch sensing piece 3 and an electrical connection 4. The water outlet elbow 2 is at least partially made of metal material. The touch sensing piece 3 always keeps in contact with the metal material portion of the water outlet elbow 2. When the user touches any position or a specific position of the water outlet elbow 2, a trigger condition can be formed to prompt the electric water faucet to perform working states such as water outlet or heating. It is more intelligent, convenient, reasonable and reliable, and avoids the situation where, for example, a solution using a far-infrared sensor as a trigger component is misjudged based on the user passing by or approaching.

[0025] In a preferred embodiment, the upper end of the water tank cover 1 is also formed with an upper open mounting groove 11 around the water through hole 10, and the lower end of the water outlet elbow 2 can be rotatably assembled in the mounting groove 11. The side wall of the water tank cover 1 is also provided with an open groove 12 connected to the mounting groove 11, and the touch sensor sheet 3 at least partially passes through the open groove 12 from the outside to the inside and abuts against the outer wall of the water outlet elbow 2. Figure 2 and Figure 3 As shown, the main part of the touch sensing sheet 3 is in a horizontal "V" shape in the cross-sectional direction, and the touch sensing sheet 3 is elastic and the protruding part abuts against the outer wall of the water outlet elbow 2. It can ensure that the touch sensing sheet 3 and the water outlet elbow 2 are always in abutment when the water outlet elbow 2 is rotated to any angle. In addition, the water outlet elbow 2 can also be designed as a fixed structure that cannot be rotated or is limited to a certain angle of rotation, but is not limited to this.

[0026] As a further preferred embodiment, the touch sensing sheet 3 is fixed to the water tank cover 1 by screws, and a wiring groove 7 is formed on the outer wall of the inner tank 6 of the electric water faucet in an inwardly recessed direction, and the electrical wiring 4 is arranged in the wiring groove 7. Furthermore, a wire pressing cover plate 8 is clamped on the wiring groove 7 to hide and protect the electrical wiring 4. Furthermore, the wiring groove 7 is a strip groove structure extending along the longitudinal direction of the outer wall of the inner tank 6, and the water tank cover 1 is detachably assembled on the upper end of the inner tank 6.

[0027] As a further preferred embodiment, the entire water outlet elbow 2 is made of metal, that is, the user can trigger the touch sensor sheet 3 by touching any position of the water outlet elbow 2. Obviously, it is also possible to consider setting a metal ring on the outer wall of one end of the water outlet elbow 2 and extending it in the direction of the other end to form a contact area, which can also be changed to a structure in which the touch sensor sheet 3 can be triggered only when the contact area is touched for the above technical purpose.

[0028] In addition, the electric water faucet includes an inner tank 6, a water inlet assembly 16 and a water outlet assembly mounted at the upper and lower ends of the inner tank 6, and a water storage and heating chamber is formed in the inner tank 6, a water inlet channel is formed in the water inlet assembly 16, and a water outlet channel is formed in the water outlet assembly, and the water through hole 10 serves as a part of the water outlet channel. An on-off control device 15 electrically connected to the control circuit board 5 is also provided on the water inlet assembly 16, and the on-off control device 15 is used to control the on-off relationship between the water inlet channel and the water storage and heating chamber. However, it is obvious that it can also be considered to be arranged in the water outlet assembly, or one is provided in the water inlet assembly 16 and the water outlet assembly respectively, and it is not limited to this. Furthermore, the on-off control device 15 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.

[0029] The electric water faucet in this embodiment also includes a housing 13 arranged outside the inner tank 6, a control valve assembly arranged on one side of the inner tank 6 and used to control the flow of liquid after passing through the on-off control device 15 and the flow between the water storage and heating chamber, an electric heating pipe 14 arranged in the inner tank 6, and a digital display assembly arranged on the inner tank 6 and the housing 13. In consideration of simple wiring, the electrical connection 4 is electrically connected to the control circuit board 5 via the wire board 9 of the digital display assembly. At the same time, the control circuit board 5 assembly is also connected to a power line extending outward from the housing 13, which is a common structure in the field of electric water faucets or a structure that can be ignored in this solution, so it is omitted in this embodiment. And. The control circuit board 5 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 3 and the solenoid valve to act, the control solenoid valve is switched to a closed state again to block the water inlet channel and the water storage and heating chamber, or after the control valve assembly is switched to a closed state, the solenoid valve is prompted to switch to a closed state, which can be based on the user's choice and usage requirements. The metal material is preferably stainless steel but may also be copper, iron, aluminum or other alloys.

[0030] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
