Abstract: The present application belongs to the technical field of humidification devices which comprises a detachably connected main unit and a water tank. An atomizing chamber is formed in the main unit, with a water inlet and an overflow port in the atomizing chamber. The atomizing chamber has a with a rim that surrounds the water inlet. Both the overflow port and the water inlet are connected to the water tank. A water stop valve is provided on the main unit which is used to close the overflow port when the main unit is detached from the water tank. Besides normal operation, the humidifier is capable of preventing the liquid to be atomized from dripping onto objects such as the ground or table after the main unit is detached from the water tank, thereby improving the user experience.

Abstract: A dust-air separation device and vacuum cleaner comprises a housing with an air inlet channel, a cyclone separation chamber, and a dust collection chamber, the air inlet channel and the dust collection chamber are connected to the cyclone separation chamber, and an air outlet is formed on the housing; the inner peripheral wall of the cyclone separation chamber is provided with an air deflector extending along the flow direction of the airflow in the cyclone separation chamber. A first separator and the second separator are respectively located on opposite sides of the air deflector along the axial direction of the cyclone separation chamber, and the first separator and the second separator are both connected to the air outlet. The dust-air separation device reduces filter clogging and sudden drops in suction power such that the device has better vacuuming performance.

Abstract: A base of a humidifier includes a housing, an air outlet assembly, and a first partition. The housing includes a receiving chamber, a first air inlet, and a second air inlet. The air outlet assembly is disposed in the receiving chamber and includes a fan, a temperature and humidity sensor, and an aroma component. The first partition is disposed in the receiving chamber and configured to spatially separate the temperature and humidity sensor from the fan and the aroma component. The fan is configured to introduce a first airflow from the first air inlet to pass through the temperature and humidity sensor, and reach the fan; introduce a second airflow flow from the second air inlet to pass through the aroma component without passing through the temperature and humidity sensor, and reach the fan; and discharge the first second airflow out of the receiving chamber through the air outlet.

Abstract: A mounting bracket for an electronic device is provided. The mounting bracket includes a first mounting member and a second mounting member. The first mounting member is configured to detachably accommodate a body of the electronic device and limit a position of the body. The second mounting member is configured to detachably accommodate an adaptor of the electronic device and limit a position of the adaptor. The first mounting member is fixedly connected to the second mounting member.

Abstract: A data processing method is provided. A terminal device encrypts a target instruction and a first identifier using a first key to obtain a first ciphertext; and sends the first ciphertext to an IoT device through an IoT platform. The IoT device decrypts the first ciphertext using a second key to obtain the target instruction and the first identifier; determines whether the first identifier matches a second identifier stored locally and comes to a matching result, the first key and the second key being negotiated by the terminal device and the IoT device; and obtains a second cipher text by encrypting the matching result using the second key. The terminal device receives the second ciphertext returned by the IoT device through the IoT platform; decrypts the second ciphertext using the first key to obtain a decryption result; and performs a corresponding operation using the decryption result.

Abstract: A control system for a terminal device includes a retrieval circuitry, a computing circuitry, a power circuitry, and a control circuitry. The retrieval circuitry is arranged to receive a plurality of electrical signals transmitted from a sensor of the terminal device. The electrical signals correspond to a first operational status thereof. The computing is arranged to determine a first variable value based on the electrical signals and a reference value. The power circuitry is arranged to retrieve a remaining power level of the terminal device, and determine a second variable value based on the remaining power level. The control circuitry is arranged to drive the terminal device to switch from the first operational status to the second operational status when the first variable value is greater than the second variable value.

Abstract: An air purifying prompting system includes an air purifying system and a prompting server wirelessly communicated with the air purifying system. The air purifying system includes an air purifying processor, an air filter communicating with the air purifying processor, a positioning module for positioning the air purifying system, and an air quality sensor for detecting air quality around the air purifying system, wherein the prompting server is arranged to generate an air filter usage time data. The air filter usage time is used to activate generation of air filter prompting signals to the air purifying system.

Abstract: A humidifier includes a base housing having a receiving cavity and an air outlet, a water tank having a vapor outlet, a vaporizing arrangement having a vaporizer and a fan, and a waterproof arrangement. The waterproof arrangement includes a blocking member movably mounted on the base housing to selectively move between an opened position and a closed position, wherein when the water tank is detached from the base housing, the blocking member is driven to block the air outlet so as to prevent water from passing through the air outlet, wherein when the water tank is attached on the base housing, the blocking member is driven to unblock the air outlet so as to allow air created by the fan to flow through the air outlet.

Abstract: A network configuration method for an IoT device is implemented by a terminal device. The method includes receiving attribute information broadcasted by N IoT devices, N being an integer greater than 1; determining a target IoT device from the N IoT devices based on at least one of: whether the attribute information broadcasted by the N IoT devices includes a selected identifier, or a first selection instruction input by a user; establishing a first communication connection with the target IoT device; sending a query request to the target IoT device to have the target IoT device return a network list corresponding to the target IoT device; determining a target network from the network list; and sending configuration information of the target network to the target IoT device so that the target IoT device performs network configuration based on the configuration information of the target network.
