  • Patent number: 10788224
    Abstract: A water-cooled fan includes a body having an air inlet and an air outlet; a fan unit corresponding to the air inlet or the air outlet; an installation slot placed between the air inlet and the air outlet; and a water supply unit disposed above the installation slot. A method for controlling a multifunctional fan includes configuring a functional space and providing a water supply unit at a top end of the functional space; optionally providing a honeycomb or an air filter unit in the functional space; and when the honeycomb is provided in the functional space, providing, by the water supply unit, dampening water for the honeycomb. The present invention can selectively achieve the effect of air humidification or air purification by using a honeycomb or an air filter unit as needed, and the water-cooled fan of the present invention has high intelligence. A multi-purpose set reduces the cost.

    Abstract: A device and a method for continuous and adjustable dosage of fluids at low pressure. The invention is self-cleaning and low tech. It consists of a tapering dosage unit in which a filling, which allows fluids to pass in the longitudinal direction of the dosage unit, is inserted. At the outlet end of the dosage unit, a venturi tube is located which clamps the filling and thereby create a nozzle opening that fits the fluids viscosity and the pressure for a given desired dosage. When the dosage unit clogs, a flushing can be obtained by either increasing the pressure of the fluid and thereby forcing a flexible dosage unit to increase the sectional area and allow cleaning or in the same way through a mechanical opening of the dosage unit.

  • Patent number: 7883028
    Abstract: A device adapted to provide volatile liquid material to an atmosphere, comprising a reservoir containing volatile liquid material, a rod-like transfer member extending therefrom and adapted to transfer liquid from the reservoir, and at least one diffusion surface adapted to receive the liquid from the transfer member and facilitate its evaporation into the atmosphere, the diffusion surface extending essentially laterally from the transfer member and comprising at least one non-integral, non-porous sheet bearing a surface capillarity, which sheet has an extent and a capillarity sufficient to allow an appropriate evaporation. The device is cheap and easy to construct, versatile and diffuses odor without major changes of the odor over time.

  • Patent number: 7819336
    Abstract: A fragrance is held in one or more layers of a three-layer liquid mixture. The three layers are mutually immiscible to form an aesthetically pleasing effect while the specific gravities of the layers are adjusted so as to provide for their transfer to the atmosphere via a simple wick. Such adjustment is determined as a function of the wicking material that is used. The formulation of the mixture involves the combination of two mutually immiscible non-aqueous components that are temporarily rendered miscible during the formulation process.

  • Patent number: 7798422
    Abstract: A cedar oil evaporator includes: a housing having openings therein for ventilation of air; a reservoir within the housing containing cedar oil; and a carrier for wicking away the cedar oil from the reservoir for dispersing cedar oil via air that passes through the housing. Each carrier is a length of cotton twine having a diameter of one-sixteenth of an inch or smaller and a length of twelve and one-half feet or longer. The housing includes a door movable about a hinge between a first position, wherein the reservoir is accessible for removal from the housing; and a second position, wherein the reservoir is inaccessible for removal. An extent of the carrier that is received within the reservoir for immersion in the cedar oil preferably represents 10% or less of the overall length of the carrier, the remainder being randomly exposed within the interior space of the housing.

  • Patent number: 7785699
    Abstract: A protective covering constructed from an electrostatically charged sheet having a top and bottom surface and an absorbent layer. The absorbent layer has top and bottom surfaces, the bottom surface of the absorbent layer being bonded to the top surface of the electrostatically charged sheet. The absorbent layer is divided into a plurality of cells for containing liquid spilled on the absorbent layer. The absorbent layer can be constructed from paper, open cell foam, fibrous mat, or any other absorbent material. In the preferred embodiment of the present invention, the cells are constructed by providing hydrophobic barriers in the absorbent layer. The barriers can be constructed from paraffin, plastic, or any other material that can penetrate the absorbent layer. In one embodiment of the present invention, a hydrophobic layer is bonded to the top surface of the absorbent layer.
