Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0018] The specific embodiments of the utility model will be described in detail below in combination with the drawings.

[0019] Please refer to Figure 1 The first embodiment of the utility model discloses a zero-power consumption power supply device, which comprises a substrate, a battery module, a switch module and a switch tube module arranged on the substrate, one end of the switch module is electrically connected with the output end of an external controller, the control end of the switch tube module is electrically connected with the other end of the switch module, the first end of the switch tube module is electrically connected with the battery module, and the second end of the switch tube module is electrically connected with the power supply end of an external controller.

[0020] The switch module is configured to detect whether there is a key operation, and the switch tube module is configured to turn on or turn off the connection between the battery module and the external controller.

[0021] Specifically, in the embodiment, the circuit structure of the zero-power consumption power supply device is as shown in the figure Figure 1 The device increases a non-self-locking key detection circuit on the circuit, SW1, that is, the switch module is connected to the MCU to judge whether there is a key operation.

[0022] When the product is working normally, the controller MCU of the remote controller controls Q1, that is, the switch tube module to turn on to realize continuous power supply and meet the normal power supply use; when the product completes the periodic work and enters standby, the control switch tube module Q1 is cut off to realize zero-power consumption standby.

[0023] The zero-power consumption power supply device realizes the zero-power consumption state of the circuit by using the combination of the controller MCU, the MOS tube, the diode and the non-self-locking switch. Specifically, when the controller MCU does not need to perform data processing or control operation, its static current is zero, thereby avoiding continuous discharge of the battery and effectively prolonging the service life of the battery.

[0024] Preferably, the switch tube module is a PMOS tube.

[0025] Preferably, the control end of the switch tube module is the gate of the PMOS tube, the first end of the switch tube module is the source of the PMOS tube, and the second end of the switch tube module is the drain of the PMOS tube.

[0026] Specifically, in the present embodiment, the PMOS tube is a P-type metal-oxide-semiconductor field-effect transistor, and its conduction is achieved by applying a voltage lower than the source voltage to the gate. When the gate voltage decreases to a certain extent relative to the source voltage, a conductive channel will be formed in the channel region of the PMOS tube, allowing current to flow from the source to the drain. Specifically, when the gate voltage is lower than the source voltage, an N-type conductive channel will be formed in the P-type semiconductor material below the gate, which allows electrons to flow, thereby realizing the conduction of the PMOS tube. By adjusting the gate voltage, the width of the conduction channel and the degree of conduction can be controlled, thereby controlling the size of the current.

[0027] In the present embodiment, when the switch module is connected, the gate of the PMOS tube is grounded, a voltage difference is formed between the gate and the source, and the PMOS tube is turned on, so that the battery module is connected to the controller of the remote controller and powers the controller of the remote controller. Conversely, when the switch module is disconnected, the PMOS tube is not turned on, and the battery module does not power the controller of the remote controller.

[0028] It should be noted that in other embodiments, other types of switch tube modules can also be used, which are not limited here, but these solutions are within the protection scope of the present application

[0030] Specifically, in the present embodiment, the ADC battery voltage detection module is configured to detect the voltage state of the battery module; when it is detected that the battery is in a low power state, one end BAT_AD of the ADC battery voltage detection module detects that the PMOS tube is controlled by the controller MCU to cut off the battery, effectively preventing the risk of battery leakage.

[0031] The zero-power consumption power supply device selects low-power consumption power electronic devices such as MOS tubes and diodes by reasonable selection and control of power electronic devices, reduces power loss and heat generation, and realizes efficient power management.

[0032] Briefly speaking, the zero-power consumption power supply device adopts a large-capacity battery, and when the battery power is lower than a certain value, the power supply is disconnected by the control circuit to prevent over-discharge of the battery; by reducing the power consumption of the remote controller, the frequency of battery replacement and charging is reduced, and the user experience is improved.

[0033] Preferably, it further comprises a shell, and the substrate is arranged inside the shell.

[0034] Specifically, in the present embodiment, the substrate serves as the central frame of the zero-power consumption power supply device, carrying devices such as battery modules, switch modules, and switch tube modules, ensuring their correct installation and electrical connection. The design of the shell fully considers dustproof, moistureproof, and impact resistance to protect the internal components from the external environment, and also facilitates the installation and maintenance of the entire device.

[0035] In summary, the zero-power consumption power supply device reduces the power consumption of the remote controller by optimizing the circuit design of the remote controller and using low-power consumption power electronic devices. The specific implementation can be to use low-power consumption MCUs and control circuits, and to completely cut off the power supply when the remote controller is not working, achieving zero power consumption. In addition, the zero-power consumption power supply device can effectively reduce the consumption of the battery due to its low power consumption and efficient power management, thereby reducing the amount of discarded batteries and being beneficial to environmental protection. In general, the zero-power consumption power supply device has the advantages of low power consumption, high efficiency, convenient use, energy saving, and environmental protection, etc., and has significant superiority compared with the prior art.

[0037] Preferably, it further comprises a controller arranged inside the remote controller body, one end of the switch module is electrically connected with the output end of the controller, and the second end of the switch tube module is electrically connected with the power supply end of the controller.

[0038] Preferably, it further comprises a remote radio frequency module arranged inside the remote controller body, the input end of the remote radio frequency module is electrically connected with the output end of the controller, and the remote radio frequency module is configured to emit radio frequency signals to control corresponding electronic equipment.

[0039] Specifically, in the present embodiment, the zero-power supply device can be applied to a remote controller, and due to its zero power consumption and efficient power management, the power consumption of the remote controller is greatly reduced. This makes the battery replacement and charging of the remote controller more convenient, and improves the user experience. By optimizing the circuit design of the remote controller, such as adopting filter circuit and voltage stabilizing circuit, the anti-interference ability and power stability of the remote controller are improved.

[0040] In addition, it should be noted that the zero-power supply device, due to its low power consumption, high efficiency and easy implementation, can not only be applied to remote controllers, but also be applied to other battery-powered products, such as smart home devices, wearable devices, shower type cold air remote controllers, water spray switching remote controllers, smart faucet remote controllers, toilet remote controllers, etc., and has wide application prospects.
