Abstract: A multifunctional infrared induction water sprinkler includes a water inlet pipe (10), an infrared induction control device (20) connected with the water inlet pipe (10), and a water outlet device (30), wherein the water outlet device (30) is connected with the infrared induction control device (20) through a universal joint (301); the infrared induction control device (20) includes an infrared pyroelectric probe, a pre-amplifier, a central processing unit, an electromagnetic valve actuator and an electromagnetic valve which are connected in sequence, and further includes an irrigating/repelling selection controller, a sprinkling duration regulator and a sprinkling interval regulator which are connected with the central processing unit. The multifunctional infrared induction water sprinkler can effectively repel animals to protect gardens, lawns and nursery gardens against damage and can also automatically spray water to irrigate gardens, lawns, nursery gardens and the like, and water resources can be saved.

Abstract: The invention relates to a novel mouse repeller including a cavity defined by a shell and a base, and a power rectification and supply part, an ultrasonic output module and a negative ion generator which are located in the cavity, wherein the power rectification and supply part supplies power to the ultrasonic output module and the negative ion generator, the ultrasonic output module includes an ultrasonic transducer protruding out of the shell, and the negative iron generator includes a discharge electrode plate which is a detachable and cleanable electrode plate. The novel mouse repeller is of an integrated structure and has a remarkable mouse repelling effect; meanwhile, the adopted detachable and cleanable electrode plate is high in power and can be reused after being detached and cleaned, so that a powerful negative ion emitting effect is maintained, and the use cost is obviously reduced.

Abstract: An automatic goods consumption judgment system includes a container tray system, a sensor measurement system, a supporting system, a mobile terminal device, a data transmission unit, a control and data processing system, and a cloud computer. Using the Internet of Things and cloud services, the consumption tendency and consumption state of goods are automatically measured in real time through the system, data are uploaded to a cloud server, and the cloud server sends analyzed and processed data to the terminal device used by users; customers are reminded of the consumption tendency and consumption state of goods according to the analysis and judgment obtained through cloud service computation, the consumption speed of goods and the fact whether required goods need to be prepared in advance or not are determined according to the analysis and judgment.
