Description

Technical Field

[0001] The invention relates to the technical field of kitchen and bathroom equipment, and in particular to an induction faucet water outlet device. Background Art

[0002] With the advancement of technology and the continuous development of the economy, household kitchen and bathroom equipment has gradually developed towards miniaturization and intelligence. A large number of semi-automatic or fully automatic equipment has appeared in ordinary people's homes, improving the convenience of people's use of equipment in daily life.

[0003] Among such devices, there is a type of faucet device that senses water by induction. It senses objects through infrared and other methods, and will dispense water when the presence of an object is sensed. This allows users to control the water flow without touching any object when their hands are stained with dirt or when washing dishes with detergent. The operation is convenient and the environment is easy to keep clean.

[0004] However, there are some problems in the production and use of this type of induction faucet water outlet device. The induction assembly is generally integrated with the controller at one time, and the induction assembly is easily affected by objective environmental factors such as the operating voltage. The actual detection distances of various induction assemblies after being connected to the controller vary greatly, affecting the normal use of the equipment. The controller often needs to be modified during the adaptation of the induction assembly, and the manufacturing process is labor-intensive. Moreover, if the induction assembly needs to be replaced during the user's use of the equipment, a professional is required to modify it or replace the induction assembly together with the controller, which is inconvenient to maintain and has high costs. Summary of the invention

[0005] Therefore, it is necessary to provide an induction faucet water outlet device to solve the problem in the prior art that the controller often needs to be modified during the adaptation of the induction assembly, which is inconvenient to maintain and has high costs.

[0006] To achieve the above-mentioned purpose, the inventor provides an induction faucet water outlet device, including a housing, a solenoid valve, a first processor, an induction assembly and a signal line interface;

[0007] The housing includes a water inlet and a water outlet;

[0008] The solenoid valve is arranged in the housing, and the water inlet of the housing is connected with the water outlet through the solenoid valve;

[0009] The first processor is in communication with the solenoid valve, and is used to receive a signal from the sensing assembly and control the opening and closing of the solenoid valve;

[0010] The sensing assembly is connected to the shell, and includes a sensor and a second processor. The sensor is communicatively connected to the second processor, and the second processor is communicatively connected to the first processor via a signal line interface. The second processor is used to receive analog signals from the sensor and send digital signals to the first processor.

[0011] Furthermore, the solenoid valve comprises a valve body and a valve head, the valve body is provided with a water inlet end and a water outlet end, the valve head is arranged in the valve body, and a fluid channel is provided between the inner wall of the valve body and the valve body.

[0012] Furthermore, there are two induction assemblies, which are respectively arranged toward the bottom and the side of the shell.

[0013] Furthermore, the end of the signal line interface connected to the first processor uses a 5-core line interface, and the end of the signal line interface facing the second processor uses a 5-core, 4-core or 3-core line interface.

[0014] Furthermore, the sensing assembly is embedded on the shell.

[0015] Furthermore, the induction faucet water outlet device also includes a grounding wire, and the grounding wire is connected to the first processor through a wire.

[0016] Furthermore, the second processor is selected from MCU.

[0018] Furthermore, a threaded groove is provided at the water inlet end of the shell, and the threaded groove at the water inlet end of the shell is adapted to a threaded interface provided on the faucet.

[0019] Different from the prior art, the above technical solution has the following advantages: by setting an independent sensing assembly connected to the first processor, a second processor is used to convert the analog signal output by the sensor into a digital signal, and the digital signal is transmitted to the first processor, thereby avoiding the measurement accuracy of the sensor being affected by external factors or replacement. The sensor signal received by the second processor is defaulted to a standard signal, and the corresponding signal is continuously transmitted to the first processor, thereby ensuring the accuracy of the signal value, reducing the workload of adjusting the sensing assembly during the production process, and making the sensing assembly form an integral unit. When replacement is needed, only the sensing assembly unit needs to be replaced to avoid replacement of the overall electronic components, reduce maintenance costs, and ensure the convenience of equipment maintenance.

[0029] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0030] Please also read Figure 1 as well as Figure 3 The present embodiment discloses an induction faucet water outlet device, including a housing 101, a solenoid valve 201, a first processor 301 and a sensing assembly 401. The housing 101 is provided with a water inlet 102 and a water outlet. (In the present embodiment, the water inlet 102 is arranged at the top of the housing 101, and the water outlet is arranged at the bottom of the housing 101. In other embodiments, the water inlet and the water outlet may be arranged along the water flow direction in the housing, for example, the water inlet is arranged at the side of the housing, and the water outlet is arranged at the top or bottom of the housing, or when the housing is a U-shaped structure, it is arranged at the two ends of the U-shaped structure of the housing.) The solenoid valve 201 is arranged in the housing 101. The solenoid valve 201 includes a water inlet end and a water outlet end. The water inlet end of the solenoid valve 201 faces the water inlet 102 of the housing 101, and the water outlet end of the solenoid valve 201 faces the water outlet of the housing 101. The first processor 301 is connected to the solenoid valve 201 through a data line communication, and is arranged in the housing 101 (in this embodiment, the first processor can realize independent operation in the housing through an independent space or a preset waterproof structure in the housing. In other embodiments, it can also be assembled on the outside of the housing and separated from the water flow area to achieve a waterproof effect). The sensing assembly 401 includes a sensor 402 and a second processor 403. The detection end of the sensor 402 faces the outside of the housing 101. The data transceiver end of the sensor 402 is connected to the second processor 403 through a data line, and the second processor 403 is connected to the first processor 301 through a data line.

[0031] According to the above structure, in the actual assembly process of the inductive faucet water outlet device, the second processor of the inductive assembly is connected to the first processor through a data line. After the inductive assembly starts working, the inductive assembly sends the sensed analog signal to the second processor. The second processor receives the analog signal sent by the inductive assembly and sends a digital signal to the first processor. After the first processor receives the signal from the second processor, the electromagnetic valve transmits an opening or closing signal to control the opening and closing of the electromagnetic valve. By setting the second processor, the signal output by each inductive assembly is defaulted to a standard distance signal, so that if each inductive assembly outputs different analog signals due to manufacturing tolerance, the influence on the default detection distance of the first processor is avoided. The accuracy of the signal value is guaranteed, and the workload of adjusting the inductive assembly during the production process is reduced. During the maintenance process, only the data line on the inductive assembly needs to be separated from the first processor, and the inductive assembly can be reused after it is replaced. Only the inductive assembly unit needs to be replaced, which avoids the need to replace the overall electronic components when the first processor, the second processor and the inductive assembly are integrated on the entire circuit board, thereby reducing the maintenance cost and ensuring the convenience of equipment maintenance.

[0032] See also Figure 2 In some preferred embodiments, the solenoid valve 201 includes a valve body 202 and a valve head 203. The water inlet and the water outlet of the solenoid valve 201 are arranged on the valve body 202. The valve head 203 is assembled in the valve body 202. A fluid channel is arranged between the inner side of the valve body 202 and the valve head 203. The end of the valve head 203 faces the water outlet of the valve body 202. By arranging the valve body and the valve head arranged in the valve body, a fluid channel with space all around is formed in the valve body. The valve head realizes water flow control by opening and closing the water outlet, thereby increasing the water flow of the solenoid valve and preventing the solenoid valve from being easily clogged.

[0033] In some preferred embodiments, there are two sensing assemblies, and the sensing ends of the sensors of the two sensing assemblies are respectively directed toward the side and bottom of the housing. By providing two sensing assemblies, the side and bottom of the induction faucet water outlet device are detected, which is convenient for increasing the detection range to adapt to various daily usage situations.

[0034] See also Figure 1 In some preferred embodiments, a signal line interface is further included. The second processor 403 of the sensing assembly 401 is connected to the first processor 301 via the signal line interface. The signal line interface is divided into two parts, one part of which is connected to the first processor 301, and the other part of which is connected to the second processor 403. The signal line interface connected to the first processor 301 is a 5-core interface, and the signal line interface connected to the second processor 403 can be a 5-core, 4-core or 3-core interface. By setting the signal line interface,

[0035] After the first processor is connected to the induction assembly, the first processor will send a request signal (handshake). When the induction assembly has a response signal feedback, indicating that the handshake is successful, the digital signal serial communication is output, the signal connection is made and the solenoid valve is driven to work; when the response signal from the induction assembly cannot be received within a certain preset time after the request signal is sent, the first processor automatically recognizes and switches to the analog signal channel to connect the signal drive circuit. It is convenient to combine and separate the induction assembly and the first processor, and when the induction assembly is switched to analog signal transmission or digital signal transmission, the 5-core interface used by the analog signal or the 3-core or 4-core interface used by the digital signal can be identified by the first processor.

[0036] See also Figure 1 In some preferred embodiments, the sensing assembly 401 is embedded in the shell 101. By embedding the sensing assembly in the shell, the detection end of the remote sensing device and the shell surface are in the same plane, reducing the protrusion on the surface of the water outlet device. The sensing assembly embedded in the shell surface is easy to be noticed by the user, which facilitates the use of the water outlet device.

[0037] See also Figure 3 In some preferred embodiments, a grounding wire 601 is further included, and the grounding wire 601 is connected to the first processor 301. By setting the grounding wire, it is convenient to guide the instantaneous large current to avoid damage to the electrical components in the water outlet device.

[0038] In some preferred embodiments, the second processor is an MCU.

[0039] In certain preferred embodiments, the shell has a threaded groove on the water inlet, and the threaded groove of the shell water inlet is matched with a preset threaded interface on the water outlet device. By providing the threaded groove and the matching threaded interface, the assembly and disassembly of the water outlet device is facilitated.

[0040] In the above embodiment, the first processor can realize the opening and closing of the solenoid valve through an amplifier and other devices. Amplifying the signal to realize the control of the valve body is an existing common technology and will not be elaborated here.

[0041] It should be noted that, although the above embodiments have been described in this article, the scope of patent protection of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, changes and modifications made to the embodiments described herein, or equivalent structures or equivalent process changes made using the contents of the present specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the patent of the present invention.
