A sterilization and disinfection device includes a housing. A control board, a humidification water tank, a humidification water trough, an ultrasonic humidifier and an ozone water tank are provided inside the housing. The humidification water trough communicates with a humidification outlet through a humidification pipe. A humidification air input channel is connected to a humidification fan connected to a humidification air inlet. The ozone water tank is equipped with an electrolytic ozone generator. The ozone water tank communicates with an ozone gas outlet through an ozone gas output pipe and a mixing chamber. The ozone water tank communicates with a water filling port through a water filling pipe. An ozone fan is installed in an ozone air inlet. The control board is electrically connected to the button display panel, the ultrasonic humidifier, the electrolytic ozone generator, the ozone fan, the humidification fan and the power inlet, respectively.

Disclosed are devices, systems and methods for controlling scent delivery by a scented article for beverage containers. In some aspects, a scent delivery system includes a cap attachable to a beverage container; and a scented article that couples to the cap, wherein the cap comprises a base, a movable component coupled to the base and able to move between a first position and a second position, and a scent chamber including an encasement to which the scented article is attached, the encasement coupled to the movable component or the base, wherein a portion of the scented article is exposed to air from an outside environment with respect to the cap when the movable component is in the second position, and wherein the encasement creates a contact seal to enclose the scented article within the scent chamber and lock in the scent when the movable component is in the first position.

The present invention relates to a solid fragrance composition which can improve the load rate of a fragrant material, can selectively load a fragrance which can be acquired during the aging process of a mixed fragrant material, maintain the fragrance from the beginning of the loading, and improve the longevity of the fragrance at a uniform strength. In addition, the issue of being harmful to the human body can be resolved by reducing powder flying around, and stability at a high temperature can be improved so as to be applied in various environments.

A display container for displaying an aromatic botanical specimen includes: (a) a container body for enclosing the botanical specimen and scented air having a scent of the botanical specimen; (b) at least one scent discharge port in the container body; and (c) an air pump coupled to the container body and operable to discharge the scented air from within the container body to the environment through the scent discharge port.

Systems and methods for detecting, capturing and/or disinfecting viruses. A water trap system includes a water-filled container through which air is introduced into a water-filled container. Charged viruses, bacteria and other contaminants become trapped in the water-filled container as they are entrapped by oppositely charged atoms (e.g., oxygen). Another device incorporates an electric field created by a pair of electrodes with an outer surface heated to a threshold temperature significant enough to disinfect viruses that come into contact therewith. Another device is a portable inhaler for detecting the polarity of airborne viruses and counting the positive and negative electrical charges of airborne viruses with tolerances of a few charged particles per cubic centimeter by sampling several hundred cubic centimeters of air per second. Consequently, the portable inhaler is capable of quickly and efficiently detecting whether a person has contracted a virus (e.g., COVID-19 virus).

A scent dispenser/absorber includes a container, an invertible lid reversibly attached to an open end of the container, a vented cage, and a scent cartridge housed within the cage after being procured from a repository or so-called “scent library.” In an “off” condition or state, the scent cartridge/cage combination is received in an interior chamber of the container, where the scent cartridge is out of communication with the surrounding environment and therefore incapable of performing scent dispensing or absorbing functions. The scent dispenser/absorber can be switched to an “on” condition or state by manually inverting the lid and hence the associated cage/scent cartridge combination such that the scent cartridge can be positioned externally of the container, where it can communicate with the surrounding environment to perform a desired scent dispensing or absorbing function. In an “on” condition, scent molecules originating from an odorant contained in a reticulated, hydrophilic inner core of the scent cartridge pass through a thermoplastic outer skin of the scent cartridge before being diffused into the surrounding environment.

A scent producing assembly includes a self-contained module comprising an absorptive matrix infused with a volatile composition and a housing. The housing includes a receptacle shaped to receive the module, at least one energy source (1004), such as an electrically heated plate, and at least one air gap (2062) located between the energy source and the receptacle. Heat from the energy source is transferred to air within the at least one air gap and to the module, which creates a draft through the at least one air gap that enhances release of the volatile composition from the heated module.

A portable scent dispensing ashtray includes an enclosure and a lid. The enclosure comprises an ash retaining portion, an absorbent retaining portion, and a dispenser retaining portion. An absorbent is retained by the absorbent retaining portion. A dispenser is retained by the dispenser retaining portion and stores odor neutralizing matter that is to be absorbed by the absorbent. The lid is rotatably attached to an upper end of the enclosure such that the lid opens or closes. When the lid opens, the ash retaining portion is exposed allowing ash or waste to be deposited into or removed from the ash retaining portion. When the lid closes, the lid activates the dispenser causing the odor neutralizing matter to be released and absorbed by the absorbent. The ashtray is portable and fits into any standard cup holder. The ashtray automatically provides odor neutralization without having to carry a separate odor neutralizing spray.

A multifunctional physical store system with automatic sterilization and disinfection functions includes a central process device, and a disinfection device, an order device, a sterilization device, and a serve device that are coupled with the central process device. The system is applied to a physical store. The disinfection device is applied for carrying out the disinfection operation on the environment of the physical store. The sterilization device is applied for carryout surface sterilization on the people entering the store. The order device and the serve device are applied for people to order and acquire meals. Therefore, the application of various devices facilitates a nearly dust-free and sterile environment in the store, lowering the possibility of virus or bacterial infection between people in the operation area and the customers.

A shoe care apparatus including a chamber including an air inlet and an air outlet; a first duct connected to the air outlet and having an evaporator and a condenser arranged inside; a second duct connected to the first duct and the air inlet; a holder arranged in the chamber and connected to the air inlet; a fan configured to circulate air through the first duct, the second duct, the holder, the chamber; a compressor configured to discharge a refrigerant to the condenser; a first temperature sensor configured to measure a first temperature of air heated by the condenser; and a controller configured to determine a target temperature of the heated air based on the user input, operate the compressor at the operation frequency based on the target temperature and outside air temperature, and control the operation frequency of the compressor based on the target temperature and the first temperature.
