A cylindrical humidifier, including a housing, a water tank, an atomization assembly, and a water feed assembly. The water tank is mounted in the housing, and is detachably connected to the atomization assembly. A lower end of the atomization assembly is arranged in the housing while an upper end thereof is detachably connected to a top end of the housing. The water feed assembly is mounted at the bottom of the atomization assembly and the water tank. The water feed assembly includes a lever bracket, a sealing bar, a pushing block, a spring, a pushing ball, a pushing bar, and a float. Water entering the water tank is controlled through the water feed assembly, so that the humidifier can maintain a constant water depth, and is always kept in the best working state, thereby achieving the maximum atomization efficiency.

A humidifying apparatus includes a nozzle and a base on which the nozzle is mounted. The nozzle has respective first and second air inlets, air outlets and interior passages for conveying air therefrom and thereto. The nozzle defines a bore through which air outside the humidifying apparatus is drawn by air emitted from the air outlets. The base generates first and second air flows through the respective first and second interior passages, and a water reservoir. First and second air passageways convey the first and second air flows to the respective first and second air inlets. As the second air passageway conveys the second air flow over the water in the reservoir, water stored in the reservoir is agitated. An ultraviolet radiation generator irradiates the agitated water for a period of time before water stored in the reservoir is atomized to increase the humidity of the second air flow.

The disclosure is related to a blowing apparatus with expandable functions, an expansion device, and an operating method. The blowing apparatus has an electrical interface used to connect one of the expansion devices with various functions. The blowing apparatus has a control unit used to identify an operating mode of the expansion device connected with the blowing apparatus. A control signal is therefore generated. According to the control signal, the control unit controls rotating speed of a fan unit and a heating temperature of a heating unit. The expansion device can be disposed with a mist unit having a container and a mist generating unit. The mist unit sprays the mist to an outlet cap of the expansion device. The blowing apparatus then blows the mist out of the outlet cap by means of the rotating speed of fan unit and the temperature of heating unit.

A portable misting fan in which the user controls the spray mist and the fan operation separately. A lower compartment stores a fluid and a pump provides the pressure to propel the fluid through a delivery tube to a spray nozzle. The flow of fluid to the nozzle is controlled by a valve that is operated by the user pushing a button. An upper compartment houses a fan which is powered by batteries and provides an air stream that is directed to the user. The fan is mounted in a fan housing in the upper compartment that is pivotally connected to the upper housing. There axe passageways in the fan housing and pivot connection for receiving the fluid delivery tube and electrical wires so that all they are all internal to the misting fan.

A cap assembly for conveying air into the interior of a container and water from the interior of the container, the cap assembly comprising a valve moveable from a first position, in which the cap assembly is closed, to a second position, in which the cap assembly is open to permit the flow of air and water through the cap assembly, the cap assembly further comprising at least two apertures through which the air and water can flow when the cap assembly is open, wherein the apertures are offset with respect to one another in a direction along the longitudinal axis of the cap assembly.

A humidifying apparatus comprising a base comprising a chamber, a water tank removably mounted on the base for supplying water to the chamber, an impeller and a motor for driving the impeller to generate an air flow, an inlet duct for conveying the air flow to the chamber, humidifying means for humidifying the air flow with water from the chamber, and an outlet duct for conveying the humidified air flow from the chamber, wherein a lower surface of the water tank, which in use supports the water tank on the base, comprises a recessed portion for receiving water overflow from the chamber.

A humidifying system having a housing one or more water filters in fluid communication with a water source, a water purifier in fluid communication with the water filters, and a water storage tank in fluid communication with the water purifier. The system further includes a water reservoir in fluid communication with the water purifier and the water storage tank, a sterilizer in communication with water carried by the water storage tank, and a dispensing line that extends to a position external to the housing. The system yet further includes a dry mist generator to generate a dry mist using water from the water storage tank, an ozone generator to generate ozone to be mixed with the dry mist and expelled from the housing via the dispensing line. The system further includes a system controller in communication with the sterilizer, the dry mist generator, and the ozone generator.

An evaporation heater arranged in a constant-temperature high-humidity storage, the evaporation heater includes a water storage tank arranged in a lower part of an enclosure of the evaporation heater; a temperature regulator configured to set water stored in the water storage tank to a target temperature; and an air blowing mechanism which is arranged in front in an air-blowing direction with respect to the water storage tank and which is configured to blow air to water in the water storage tank, set the temperature inside the constant-temperature high-humidity storage to the target temperature, and hold the humidity inside the constant-temperature high-humidity storage at saturated humidity.
