Fragrance dispensers with features that are capable of reducing wastage of fragrance, or of conserving fragrance, are disclosed. Such a fragrance dispenser may have a configuration that collects fragrance that is expelled from the fragrance dispenser, but has not vaporized or atomized sufficiently to dissipate into the environment, as well as fragrance that condenses immediately after it has been expelled from the fragrance dispenser. A spill-resistant bottle that may be used with a fragrance dispenser has a shape that orients an opening of the bottle in a somewhat upward orientation to prevent fragrance from spilling out when the bottle is tipped over. Fragrance dispensers with configurations that generate vortices to deliver fragrance into the surrounding environment are also disclosed.

A heater arrangement for a volatile material dispenser includes a cylinder defining an opening and a resistor embedded in the cylinder. The dispenser further includes a housing configured to receive a refill containing a volatile material and a wick. The housing includes a first cavity configured to support the heater arrangement. Further, the dispenser is configured such that, when the refill is received within the housing, the opening receives the wick therein so that a radial gap is formed between the heater arrangement and the wick.

The present invention discloses a novel multipurpose fast dehumidification device, in which materials with different functions can be placed simultaneously or separately, such as moisture absorption materials, aromatic materials, mosquito repelling (insect repelling) materials or deodorization materials. The present invention comprises a base, a placement frame and a circulation mechanism One end of the placement frame is movably connected with the base, and the other end of the placement frame is movably connected with the circulation mechanism; and the moisture absorption materials are placed in the placement frame. After the device is started, air in an environment is sucked by the circulation mechanism, then reaches the placement frame, and then is discharged from the placement frame after being dehumidified. The present invention has the beneficial effects that the structure is simple, and the use is convenient; the complicated structure of a traditional dehumidifier is abandoned, and the cost of a product is reduced to a maximum degree; at the same time, a single dehumidification function is expanded, which can play a role in different use scenes. That is, besides the dehumidification function, functions of atmosphere creation, mosquito repelling (insect repelling), deodorization and the like can also be realized.

To provide an aroma diffusing device and a method of controlling an aroma diffusing device that can enable a plurality of functions to be achieved by operation inputs to one operation input part.

Provided is an aroma diffusing device including: a perfume holding part in which a perfume is held; an air blowing source configured to supply air to the perfume holding part; an aroma discharge part through which the air having passed through the perfume holding part is discharged; an operation input part on which an operation input for the air blowing source is performed by a user; and an air blowing source control part configured to control a supply state of the air on the basis of an operation input on the one operation input part.

A ventilation-type UV light includes a light body, an air guide structure provided at the bottom of the light body, a UV module, a fan and two air inlets; the air guide structure and the light body enclose to form a mounting space, the UV module is installed inside the mounting space; the fan is provided inside the air guide structure, the bottom of the air guide structure is provided with air outlets, the air inlets are provided on the periphery or bottom of the ventilation-type UV light in an encircling way, and both the air inlets and the air outlets access the mounting space. Air can flow into the mounting space along the air inlets and then can be discharged downward via the air outlets after being sterilized and disinfected by the UV module in the mounting space.

An air sterilizing device has a casing, a wheel disc covered with microporous structures, a blower, and a sterilizing module. The casing has an air inlet and an air outlet. The blower located in the casing introduces the external air from the air inlet, and the external air is filtered and sterilized by the wheel disc and the sterilizing module. The filtered and sterilized air is discharged from the air outlet. The sterilizing module locates next to the wheel disc for sterilizing the air flowing through the sterilizing module and also for sterilizing the wheel disc by the relative rotation between the wheel disc and the sterilizing module. Bacteria and viruses attached to the wheel disc are eliminated, and the filtration and sterilization functions of the wheel disc are maintained. The efficacy and the efficiency of the air sterilizing device are therefore improved.

A compact diffuser integrates an atomizer and droplet separator into a surrounding sleeve, threadable to a bottle neck as an assembly. The assembly fits into a base, housing a motor and air pump, sealing the sleeve to a silo in the housing. Controls set time span of intermittent operation, intervening delay, and volumetric flow rate. The assembly pops into (and out of) the top end of a silo in the base, registering (aligning) circumferentially and axially to seal an air path from the pump to the atomizer. Access for applying force to the bottom of the assembly facilitates popping out the assembly when empty, or to simply change scent by changing out the assembly. Entire assemblies may be stored to simplify exchange and reduce chances for spills from reservoirs.

Disclosed herein is a diffuser air purification unit. The diffuser air purification unit can comprise a diffuser, a filtration chamber, a purification chamber, a blower, a housing, and a control module. The filtration chamber can be configured to receive air through the diffuser from an external setting in which the diffuser air purification unit is installed and to cause a filtration of the air when the air flows through the filtration chamber. The purification chamber can be configured to receive the air from the filtration chamber and to cause a purification of the air when the air flows through the purification chamber. The blower can be configured to intake the air from the external setting through the diffuser, the filtration chamber, and the purification chamber and to expel the air into the external setting. The housing can at least partially enclose the filtration chamber and the purification chamber. The control module can be secured to the housing and be configured to control an operation of the diffuser air purification unit.

A portable airborne pathogen control apparatus and system. Aspects of the present disclosure provide for a portable airborne pathogen control apparatus configured to be selectively positioned within an interior room and configured to enable a floor-to-ceiling flow of air within the interior room. The portable airborne pathogen control apparatus may comprise a housing with an air intake disposed at a lower area of a base housing and an air outlet disposed at an upper area of an elongated duct extending from the base housing. A blower fan housed within an interior chamber of the housing may be configured to direct a floor-to-ceiling flow of air through the interior chamber from the air intake to the air outlet. A volume of air directed through the interior chamber of the housing may be disinfected using one or more UV-C emitters and/or cold plasma generator(s) housing in the interior chamber of the housing.

A dispensing system includes a composition that includes one or more of a deodorizing composition, a fragrancing composition, or a cleaning composition. The system includes a container having a body. The composition is disposed within the container, and a pressure within the container is at least 930 kPa. The system further includes an actuator assembly coupled with the container. The actuator assembly includes a housing, an actuator positioned within the housing and comprising a fluid passageway in fluid communication with the composition, and a nozzle insert disposed within the fluid passageway. The nozzle insert defines a nozzle orifice having an orifice diameter of between about 0.335 mm and about 0.385 mm, and the composition comprises a compressed gas and between about 5% and about 10% by volume ethanol.
