Description

Technical Field

[0001] This utility model relates to courtyard equipment, and more specifically, to a courtyard equipment with an automatic switching function. Background Technology

[0002] Garden equipment includes waterfalls, fountains, drip irrigation, and other similar devices. These typically include a control unit with a control board that connects to peripheral devices to control their lighting, fountains, drip irrigation, etc. Therefore, existing garden equipment includes batteries and mechanical switches. The mechanical switch controls the on / off operation of the equipment. After the product is packaged at the factory, the mechanical switch disconnects the control board from the battery, preventing battery depletion during long-distance transportation and storage, which would affect user experience. However, existing mechanical switches not only increase costs but also negatively impact product design. Utility Model Content

[0003] To address the technical problem that existing garden equipment with mechanical switches not only increases costs but also negatively impacts product design, this invention provides a garden equipment with an automatic switching function.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is to design a courtyard device with an automatic switching function, including a battery. The courtyard device with the automatic switching function also includes:

[0005] Controller;

[0006] An electronic switch, which is connected to the controller and the battery;

[0007] A power module is connected between the controller and the electronic switch;

[0008] A light sensor is used to sense light. The light sensor is connected to the controller and the electronic switch. When the light sensor is placed in a light-shielding container, it sends a light-shielding control signal to control the electronic switch to disconnect the controller from the power module. When the light sensor is not placed in the light-shielding container, it sends an activation signal to control the electronic switch to turn on. The battery supplies power to the controller through the electronic switch and the power module. The controller outputs a control level to keep the electronic switch on.

[0009] The courtyard equipment with automatic switching function also includes:

[0010] A sampling circuit is connected to the photosensitive device and the controller. The sampling circuit samples the output voltage of the photosensitive device and outputs a first control signal to the electronic switch when the sampled voltage is lower than a first voltage value, thereby controlling the electronic switch to disconnect the electrical connection between the controller and the power module. When the sampled voltage is within a second voltage threshold range, a second control signal is output.

[0011] The light-sensing device is a solar panel or a photosensitive element.

[0012] The electronic switch includes:

[0013] The fifth resistor has one end connected to the photosensitive device;

[0014] The base of the first transistor is connected to the other end of the fifth resistor, and its emitter is grounded.

[0015] The sixth resistor has one end connected to the base of the first transistor and the other end grounded.

[0016] The first field-effect transistor has its gate connected to the collector of the first transistor, its drain connected to the battery, and its source connected to the power module.

[0017] The fourth resistor has one end connected to the drain of the first field-effect transistor and the other end connected to the gate of the first field-effect transistor.

[0018] The sampling circuit includes:

[0019] The second resistor has one end connected to the photosensitive device;

[0020] The third resistor has one end connected to the other end of the second resistor, and the other end grounded.

[0021] The controller has a sampling terminal and a first control signal output terminal. The sampling terminal is connected to the other end of the second resistor, and the first control signal output terminal is connected to one end of the fifth resistor. The first control signal outputs the control level and the first control signal.

[0022] The courtyard equipment with automatic switching function also includes:

[0023] The positive terminal of the second diode is connected to the output terminal of the first control signal, and the negative terminal is connected to one end of the fifth resistor.

[0024] The courtyard equipment with automatic switching function also includes:

[0025] The first resistor has one end connected to the photosensitive device and the other end connected to one end of the fifth resistor.

[0026] The courtyard equipment with automatic switching function also includes:

[0027] The first diode has its positive terminal connected to the photosensitive device and its negative terminal connected to the battery.

[0028] The courtyard equipment with automatic switching function also includes:

[0030] The courtyard equipment with automatic switching function also includes:

[0031] An electrical connector that is electrically connected to the controller.

[0032] This invention comprises a battery, a controller, an electronic switch, a power module, and a photosensitive device. The photosensitive device senses light and, when it is placed in a light-shielding container, sends a light-shielding control signal to control the electronic switch to disconnect the controller from the power module. When the photosensitive device is not placed in the light-shielding container, it sends an activation signal to control the electronic switch to conduct. The battery supplies power to the controller through the electronic switch and the power module, and the controller outputs a control level to keep the electronic switch conducting. Therefore, after the product is packaged in a box at the factory, the box acts as a light-proof container, preventing the light sensor from detecting light. This triggers a light-blocking control signal that disconnects the controller from the power module via the electronic switch. At this point, the controller enters a sleep state, and the product's power consumption is at the microamp level or even lower. This ensures the battery can retain energy during long-term transportation or storage without depletion. When the product is removed from the box, the light sensor detects light and triggers an activation signal that turns on the electronic switch. The battery then powers the controller through the electronic switch and power module. The controller outputs a control level to keep the electronic switch on, allowing for immediate use without requiring the user to charge the product or find a power source. This design not only reduces cost but also simplifies the product's appearance by eliminating the mechanical switch, improving design and ease of use. Attached Figure Description

[0033] The present invention will now be described in detail with reference to the embodiments and accompanying drawings, wherein:

[0034] Figure 1 This is a schematic diagram of the courtyard device with automatic switching function of this utility model;

[0035] Figure 2 This is a circuit diagram of a specific embodiment of the courtyard equipment with automatic switching function of this utility model. Detailed Implementation

[0036] The specific embodiments of this utility model are further described below with reference to the accompanying drawings:

[0037] Please see also Figures 1 to 2 This utility model of a garden device with automatic switching function includes a battery 1, a controller 2, an electronic switch 3, a power module 4, a light sensor 5, and a sampling circuit 6. Wherein:

[0038] Battery 1 is used to provide power to the controller, power module, etc. Of course, an external power source can also be connected to the battery to supplement the battery and provide power to the controller, power module, etc.

[0039] Controller 2 primarily functions as a control unit. It is fabricated on a circuit board to form a control board, and is used to control the operation of the garden equipment. In this specific embodiment, the controller is implemented using a CPU or MPU and its peripheral circuitry; specifically, it can be implemented using the STC15W408AS chip and its peripheral circuitry. Electronic switch 3, power module 4, sampling circuit 6, and other drive circuits can all be fabricated on the same control board to simplify circuit board connection and installation as much as possible.

[0040] Electronic switch 3 is connected to the controller and the battery. The electronic switch is mainly used to control the on / off state of the power module, serving as the power on / off function. When the electronic switch is off, the controller is in the off state; when the electronic switch is on, the controller is powered on and activated, entering the working state.

[0041] The power module 4 is connected between the controller and the electronic switch. The power module is mainly used for voltage supply control, thereby providing operating power to the controller.

[0042] A light sensor 5 is used to sense light. The light sensor is connected to the controller and the electronic switch. When the light sensor is placed in a light-shielding container, it sends a light-shielding control signal to control the electronic switch to disconnect the controller from the power module. When the light sensor is not placed in the light-shielding container, it sends an activation signal to control the electronic switch to turn on. The battery supplies power to the controller through the electronic switch and the power module. The controller outputs a control level to keep the electronic switch on. The light sensor is a solar panel or a photosensitive element. Since garden equipment usually has a solar panel, in this specific embodiment, the light sensor is a solar panel.

[0043] Therefore, after the product is packaged in a box at the factory, the box acts as a light-proof container, preventing the light sensor from detecting light. This triggers a light-blocking control signal that disconnects the controller from the power module via the electronic switch. At this point, the controller enters a sleep state, and the product's power consumption is at the microamp level or even lower. This ensures the battery can retain energy during long-term transportation or storage without depletion. When the product is removed from the box, the light sensor detects light and triggers an activation signal that turns on the electronic switch. The battery then powers the controller through the electronic switch and power module. The controller outputs a control level to keep the electronic switch on, allowing for immediate use without requiring the user to charge the product or find a power source. This design not only reduces cost but also simplifies the product's appearance by eliminating the mechanical switch, improving design and ease of use.

[0044] The sampling circuit 6 is connected to the photosensitive device and the controller. The sampling circuit samples the output voltage of the photosensitive device and outputs a first control signal to the electronic switch when the sampled voltage is lower than a first voltage value, thereby controlling the electronic switch to disconnect the electrical connection between the controller and the power module. When the sampled voltage is within a second voltage threshold range, the sampling circuit outputs a second control signal.

[0045] After the controller is powered on, it samples the output voltage of the light sensor through a sampling circuit. For example, the sampled voltage data of the solar panel at night is 10-3000, while the sampled voltage is less than 10 after the solar panel is placed in the packaging box. Therefore, a first voltage value of 10 and a second voltage threshold of 10-300 can be used. When the sampled voltage is less than 10, the controller determines that the product has been placed in the packaging box and outputs a first control signal to the electronic switch, controlling the electronic switch to disconnect the electrical connection between the controller and the power module, thus completely turning off the power to the product. When the sampled voltage is between 10-300, the controller determines it is nighttime and outputs a second control signal to put the garden equipment into night mode, controlling the lights, motors, etc., to turn on.

[0046] In this specific embodiment, the electronic switch includes a fifth resistor R5, a first transistor Q2, a sixth resistor R6, a first field-effect transistor Q1, and a fourth resistor R4. Wherein:

[0047] One end of the fifth resistor R5 is connected to the photosensitive device.

[0048] The base of the first transistor Q2 is connected to the other end of the fifth resistor, and the emitter is grounded.

[0049] One end of the sixth resistor R6 is connected to the base of the first transistor, and the other end is grounded.

[0050] The gate of the first field-effect transistor Q1 is connected to the collector of the first transistor, its drain is connected to the battery BT1, and its source is connected to the power module.

[0051] One end of the fourth resistor R4 is connected to the drain of the first field-effect transistor, and the other end is connected to the gate of the first field-effect transistor.

[0052] In this specific embodiment, the sampling circuit includes a second resistor R2 and a third resistor R3. Wherein:

[0053] One end of the second resistor R2 is connected to the photosensitive device.

[0054] One end of the third resistor R3 is connected to the other end of the second resistor, and the other end is grounded.

[0055] The controller has a sampling terminal (AD I / O) and a first control signal output terminal (I / O 1). The sampling terminal is connected to the other end of the second resistor, and the first control signal output terminal is connected to one end of the fifth resistor. The first control signal outputs the control level and the first control signal. The controller can also output control signals to control other functional modules through other control signal output terminals (I / O 2, I / O 3, I / O 4).

[0056] In this specific embodiment, the courtyard device with automatic switching function further includes a second diode D2, the positive terminal of which is connected to the first control signal output terminal, and the negative terminal is connected to one end of the fifth resistor.

[0057] In this specific embodiment, the courtyard device with automatic switching function further includes a first resistor R1, one end of which is connected to the photosensitive device, and the other end is connected to one end of the fifth resistor.

[0058] In this specific embodiment, the courtyard device with automatic switching function further includes a first diode D1, the positive terminal of the first diode D1 being connected to the photosensitive device, and the negative terminal being connected to the battery.

[0059] To facilitate the management of charging and discharging, in this specific embodiment, the courtyard device with automatic switching function further includes a charging and discharging module, which is connected between the battery, the negative terminal of the first diode, and the drain of the first field-effect transistor.

[0060] To facilitate connection between peripheral devices and the controller, the yard appliance with automatic switching function also includes an electrical connector, which is electrically connected to the controller. This allows for pluggable connection to peripheral devices, making installation, disassembly, and use of the yard appliance more convenient. Even when the control board is in sleep mode, its control over peripheral devices remains active. However, since the device and control board are separated during packaging, the entire product remains in a low-power state. After unpacking, the user needs to connect the device to the control board via the electrical connector, facilitating both separation from the packaging and connection after unpacking.

[0061] The working principle of this utility model is as follows:

[0062] 1. When there is sufficient light, the light-sensing device, such as the solar panel, generates a voltage level that drives the first transistor Q2 through the first resistor R1, pulling down the base voltage of the first field-effect transistor Q1. Then, the first field-effect transistor Q1 turns on, and the battery or power supply provides power to the power module, powering on the microprocessor U1.

[0063] 2. After the microprocessor U1 is powered on, it first outputs a control level from the first control signal output terminal I / O 1 to keep the first field-effect transistor Q1 and the first transistor Q2 conducting, so that the battery supplies power to the product or product module.

[0064] 3. After power-on, the microprocessor U1 samples, calculates, and analyzes the voltage levels of the AD I / O port. If a specific set value is reached, for example, the voltage level at night is 10-300, while the voltage level inside the packaging box is <10, then the microprocessor determines it is nighttime when the voltage level is between 10 and 300, and can control functions such as turning on lights and motors. Conversely, if the voltage level is greater than 300, the microprocessor determines it is daytime. If the voltage level is less than 10, the microprocessor assumes the product is already in the packaging box and outputs a control signal to turn off the power. Simultaneously, because the solar panel inside the packaging box will not have the voltage level to activate the electronic switch, the product's power is completely shut off.

[0065] 4. When the user takes the product out of the packaging box, the light sensor will detect the light and start the product from step 1. This achieves the function of an electronic switch without relying on any mechanical switch to turn off the product's power.

[0066] This invention can be used in garden products such as solar-powered waterfall ambient lights with batteries, watering devices, oxygen pumps, floating fountains, ordinary fountains, and solar-powered artificial waterfalls.

[0067] This utility model has the following advantages:

[0068] 1. It can save the cost of mechanical switches and the cost of assembling this switch;

[0069] 2. The absence of mechanical switches allows for better design of the product's appearance;

[0070] 3. For products that come into contact with water or are used outdoors, there is no need to consider the waterproofing of mechanical switches, which can save costs;

[0071] 4. The product is controlled by light-sensing intelligence, saving time and effort;

[0072] 5. After the product is packed into the box, it will immediately shut down under the control of the electronic switch, which avoids the problem of the product running out of battery power during transportation and storage and eliminates the safety hazards of the product during transportation.

[0073] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
