Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, specifically to a household water purifier luminous logo control system. Background Technology

[0002] As people's living standards improve, their requirements for drinking water quality are also increasing, leading to the widespread use of household water purifiers. Currently, household water purifiers on the market are constantly innovating in terms of appearance design and functionality to meet users' dual needs for aesthetics and functionality.

[0003] Illuminated logos, as a common product identification and decorative element, can enhance a product's overall image and recognizability. However, most existing illuminated logos for household water purifiers use a constant or fixed flashing pattern, failing to intelligently control their illumination based on the purifier's actual operating status. This fixed illumination pattern not only wastes energy but also fails to provide users with intuitive information about the purifier's operating status. When the purifier is not producing water, the continuously lit logo increases energy consumption and may cause unnecessary light interference to users in certain situations (such as at night). Conversely, when the purifier is producing water, the logo may not illuminate promptly, making it difficult for users to determine from a distance whether the purifier is working, thus reducing product convenience and user experience. Therefore, it is necessary to design a device and method that can intelligently control the illumination of the logo based on whether the household water purifier is producing water to solve the aforementioned problems. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a household water purifier illuminated logo control system, thereby solving the problem mentioned in the background art that the illuminated logo of the water purifier cannot be intelligently controlled according to the actual working status of the water purifier.

[0005] To achieve the above technical objectives, this utility model proposes the following technical solution: a household water purifier illuminated logo control system, comprising a detection module, a control circuit, and an illuminated logo. The control circuit includes a signal processing module, a control module, and a drive module. The detection module is used to detect the presence or absence of water flow in the water purifier pipeline. The signal processing module is used to receive the electrical signal output by the detection module and amplify and filter it. The control module is used to receive the signal processed by the signal processing module and determine whether the water purifier is in water production state according to preset logic. The drive module is used to control the illumination of the illuminated logo according to the signal output by the control module. The output terminal of the detection module is connected to the input terminal of the signal processing module, the output terminal of the signal processing module is connected to the input terminal of the control module, the output terminal of the control module is connected to the input terminal of the drive module, and the output terminal of the drive module is connected to the input terminal of the illuminated logo.

[0006] Furthermore, the detection module is a flow sensor, which is installed on the water inlet pipe of the water purifier near the water inlet.

[0007] Furthermore, the flow sensor is a Hall effect flow sensor or an electromagnetic flow sensor.

[0008] Furthermore, the driving module employs a transistor driving circuit or a field-effect transistor driving circuit.

[0009] Furthermore, the illuminated logo uses LED lights as the light-emitting element and is installed on the outer shell of the water purifier.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses intelligent control to turn the luminous logo on and off. When the water purifier is not producing water, the luminous logo will automatically turn off, avoiding unnecessary power consumption, reducing the overall energy consumption of the product, and conforming to the concept of energy conservation and environmental protection.

[0011] 2. Users can easily determine whether the water purifier is producing water from a distance by observing the illumination of the logo, without needing to approach the purifier to check other working status indicator lights or displays. This provides users with a more intuitive and convenient indication of the product's working status, improving the user experience.

[0012] 3. The intelligent control luminous logo, as a novel design element, can enhance the overall technological feel and intelligence of household water purifiers, strengthen the product's competitiveness in the market, and improve the product's brand image. Attached Figure Description

[0014] In the diagram, 1 is the detection module; 2 is the control circuit; 3 is the signal processing module; 4 is the control module; 5 is the drive module; and 6 is the illuminated logo. Detailed Implementation

[0015] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] This utility model provides a control system for a household water purifier's illuminated logo, including a detection module 1, a control circuit 2, and an illuminated logo 6. Both the control circuit 2 and the illuminated logo 6 are powered by the water purifier's main power supply system, which is typically AC power (e.g., 220V). The AC signal, after being stepped down, rectified, filtered, and stabilized by a transformer, outputs a DC voltage suitable for the control circuit and the illuminated logo 6. The control circuit 2 includes a signal processing module 3, a control module 4, and a drive module 5. The detection module 1 detects the presence or absence of water flow in the water purifier's pipeline to determine whether the water purifier is in water production mode. The signal processing module 3 receives the electrical signal output by the detection module 1 and amplifies and filters it to improve the stability and reliability of the signal, facilitating subsequent identification and processing by the microcontroller chip. The control module 4 receives the signal processed by the signal processing module 3 and determines whether the water purifier is in water production mode according to preset logic. If a water flow signal is detected, the water purifier is in water production mode, and the microcontroller chip outputs a high-level signal; if no water flow signal is detected, the water purifier is not in water production mode, and the microcontroller chip outputs a low-level signal. The driving module 5 is used to control the illumination of the luminous logo 6 according to the signal output by the control module 4. The output of the detection module 1 is connected to the input of the signal processing module 3, the output of the signal processing module 3 is connected to the input of the control module 4, the output of the control module 4 is connected to the input of the driving module 5, and the output of the driving module 5 is connected to the input of the luminous logo 6.

[0017] like Figure 1As shown, the control circuit is constructed by soldering various electronic components of the signal processing module 3, including amplifiers and filters, onto the circuit board. The circuit connections are made according to the designed circuit schematic. The control module uses a microcontroller chip, which is soldered onto the circuit board and connected to external power to ensure normal operation. The electronic components of the drive module are also soldered onto the circuit board, and the wires connecting the drive module, control module, and the illuminated logo are connected. The drive module can use common drive circuit forms such as transistor drive circuits or field-effect transistor drive circuits. Taking a transistor drive circuit as an example, the signal output from the microcontroller chip is connected to the base of the transistor, and the illuminated logo is connected between the collector of the transistor and the positive terminal of the power supply. When the base receives a high-level signal, the transistor conducts, and current flows through the illuminated logo, causing it to light up. When the base receives a low-level signal, the transistor is cut off, and the illuminated logo goes out. In use, when the household water purifier starts producing water, the water flow is detected by the detection module 1, which converts the water flow signal into an electrical signal output. This electrical signal is amplified and filtered by the signal processing module before being transmitted to the microcontroller chip. The microcontroller chip analyzes and judges the received signals. After confirming that the water purifier is in water production mode, it outputs a high-level signal to the drive module 5. Upon receiving the high-level signal, the drive module 5 turns on the circuit to provide working voltage for the illuminated logo, thus making the illuminated logo appear and intuitively indicating to the user that the water purifier is producing water. When the household water purifier stops producing water, there is no water flow in the pipeline, and the detection module 1 cannot detect the water flow signal, so it outputs a low-level signal. This signal is processed by the signal processing module 3 and transmitted to the microcontroller chip. The microcontroller chip determines that the water purifier is in a non-water production state and outputs a low-level signal to the drive module 5. Upon receiving the low-level signal, the drive module 5 turns off the circuit, the illuminated logo 6 loses its working voltage, and the illuminated logo stops displaying.

[0018] The detection module 1 is a flow sensor, which is installed on the inlet pipe of the water purifier.

[0019] like Figure 1As shown, flow sensors can include Hall effect flow sensors and electromagnetic flow sensors. Their working principle is based on the fact that water flowing through the flow sensor causes changes in certain physical quantities, such as magnetic field changes and electromagnetic induction. The flow sensor converts these changes into an electrical signal output. For example, with a Hall effect flow sensor, when water flows through, the magnetic material in the water causes the Hall element inside the sensor to generate a Hall voltage proportional to the flow rate. By detecting this voltage, the water flow status can be determined. The flow sensor is securely fixed to the pipeline using the matching fasteners. Then, the output signal line of the flow sensor is connected to the input terminal of the signal processing module. If a Hall effect flow sensor with a suitable pipe diameter is selected, the flow sensor should be installed near the inlet of the water purifier's inlet pipe, according to the water purifier's pipeline structure, ensuring a stable water flow through the flow sensor and that the installation process does not affect the pipeline's sealing or the normal flow of water.

[0020] The driving module 5 adopts a driving circuit such as a transistor driving circuit or a field-effect transistor driving circuit. Taking the transistor driving circuit as an example, the signal output by the microcontroller chip is connected to the base of the transistor, and the light-emitting logo 6 is connected between the collector of the transistor and the positive terminal of the power supply. When the base receives a high-level signal, the transistor is turned on, and the current flows through the light-emitting logo 6 to make it light up; when the base receives a low-level signal, the transistor is turned off, and the light-emitting logo 6 is turned off.

[0021] The illuminated logo 6 uses LED lights as the light-emitting element and is installed on the outer shell of the water purifier.

[0022] like Figure 1 As shown, the luminous logo 6 uses LED lights as the light-emitting element, which has the advantages of high luminous efficiency, long life and low power consumption. The LED lights can be arranged to form various shapes and patterns of logos or illuminate logo stickers according to product design requirements. The LED lights are connected to the driver module 5 through wires and can be turned on and off under the control of the driver module 5.

[0023] Debugging: After completing the installation of the device, connect the power supply to the water purifier and start it to enter the water production state. Observe whether the flow sensor can accurately detect the water flow signal, whether the signal processing module 3 can effectively process the signal output by the flow sensor and transmit it to the microcontroller chip, whether the microcontroller chip can correctly output the control signal to the drive module according to the received signal, and whether the drive module 5 can control the illuminated logo 6 to light up normally. If the illuminated logo 6 is found not to light up or to light up abnormally, check whether the connections between the components are loose, whether there are short circuits or open circuits in the circuit, and make corresponding adjustments and repairs. When the water purifier stops producing water, observe whether the illuminated logo 6 can turn off in time. If there is a problem, troubleshoot and solve it as well. After repeated debugging, ensure that the entire device can stably and accurately control the lighting of the illuminated logo 6 according to the water production status of the household water purifier.

[0024] Operating principle: When the household water purifier starts producing water, water flows through the pipe equipped with a flow sensor. The flow sensor detects the water flow signal and converts it into an electrical signal. This electrical signal is amplified and filtered by the signal processing module 3 before being transmitted to the microcontroller chip. The microcontroller chip analyzes and judges the received signal. After confirming that the water purifier is producing water, it outputs a high-level signal to the drive module 5. Upon receiving the high-level signal, the drive module 5 activates the circuit, providing operating voltage to the illuminated logo 6, causing the LED to light up and thus displaying the illuminated logo 6, intuitively indicating to the user that the water purifier is producing water. When the household water purifier stops producing water, no water flows through the pipe, the flow sensor cannot detect a water flow signal, and outputs a low-level signal. This signal is processed by the signal processing module 3 and transmitted to the microcontroller chip. The microcontroller chip determines that the water purifier is not producing water and outputs a low-level signal to the drive module 5. Upon receiving the low-level signal, the drive module 5 cuts off the circuit, the illuminated logo 6 loses its operating voltage, the LED turns off, and the illuminated logo stops displaying.
