  • Publication number: 20150125798
    Abstract: A heat gun adapter is an apparatus that allows the use of a heat gun in order to ignite the fuel pellets within the combustion chamber of a pellet burner, specifically manually-ignited gravity-fed pellet burner. The heat gun adapter features a base plate that is placed over the combustion chamber access port after the combustion chamber end plate is removed. A nozzle port is present in order to allow a heat gun to be inserted through the base plate. The heat gun is guided through an annular guide that is positioned concentrically with the nozzle port. The annular guide additionally serves to hold the heat gun in place without user assistance after the heat gun is inserted. The heat gun adapter is held in place between a first track and a second track on the combustion chamber by a lip.

  • Publication number: 20080276479
    Abstract: Disclosed is a hair dryer capable of improving convenience in handling, changing a temperature range of a blown air variously, and generating anions in the blown air. The hair dryer includes a manipulating panel (12) in which switches (S1,S2,S3,S4) are independently mounted, a first microprocessor (MPU1)(100) for transmitting an input signal input from each switch to a second microprocessor (MPU2)(200), and a second microprocessor (MPU2)(200) for controlling operation the driving motor according to the input signal and classifying a connection interval of electric current applied to the heating coil (C). The hair dryer allows a temperature range to be variously controlled, so the hair dryer may be utilized in more various fields, and because of using a single heating coil C, the hair dryer has very simple inner configuration, thereby reducing manufacture costs remarkably.

  • Patent number: 7428785
    Abstract: A hair dryer in which the direction of a palm of a user gripping the hair dryer is same as the direction of wind blown from the hair dryer. A blowing pipe is coupled to a case and has an air outlet at one end. A heater for heating air is provided inside the case. A fan for blowing air toward the heater and the air outlet is provided inside the case. A grip part, which is designed to be gripped by a human hand, is coupled to a portion of the case opposite to the air outlet. A handle is mounted to the grip part so as to prevent the grip part from being released from the band.

  • Patent number: 7326883
    Abstract: A housing and a base formed integrally with the housing or attached thereto. An array of louvres is attached to or formed integrally with the housing. An electric motor-driven fan is located within the housing and blows air toward the louvres. An electric heating element is situated within the housing between the fan and the array of louvres. This avoids subjecting the fan to excessive heat of the heating element and reduces turbulence of airflow past the louvres, thereby reducing operational noise levels.

  • Patent number: 7300484
    Abstract: A blower has a carrying frame provided with a base plate. A fan with a fan housing is mounted on the carrying frame. The fan housing has an intake opening that faces the base plate and is spaced from the base plate. An intake gap is formed between the base plate and the fan housing. An internal combustion engine drives the fan in order to take in working air through the intake opening and to blow out the working air through a blower tube. A leaf shield for preventing leaves and debris from entering the fan housing is provided and covers the intake gap. The leaf shield is made of a foam material having coarse pores to allow unimpaired intake of the working air and to prevent leaves or other debris from adhering to the leaf shield.

  • Patent number: 7095953
    Abstract: The device comprises a container (1) of active substance in liquid form, which is sealed by means of a permeable membrane (3) which lets the active substance vapour pass and prevents the passage of liquid, being completed with a porous support (5) on the inner face of the membrane (3), so as to take the active substance to the centre of the membrane (3), this being warmed by a heater element (9) with pins (10) which are coupled directly onto the pins (8) of a socket plug (7), via which the device is powered, so that the evaporation of the active substance takes place by warming and it issues to the exterior by ways of slots (12) provided in a housing (11) which joins the container (1) to the socket plug (7). The assembly forms a disposable device, although the container (1) can be embodied so that it is interchangeable.

  • Patent number: 7002442
    Abstract: A safety switch apparatus for disabling the operation of a hand-held appliance, e.g., a hair dryer, during periods of nonuse such as when the appliance is put down on a prescribed surface or placed in a non-functional position such as being held under a user's arm. In a first implementation, a sensor is coupled to control circuitry within the appliance to remove power from portions of the device, e.g., its motor and/or heater, when the appliance is proximate to an externally-provided magnetic field preferably provided from a magnetic element typically contained within a pad placeable on a work surface, within the work surface, or a wearable piece of clothing. In a second implementation, the converse occurs, i.e., a sensor is used to sense the presence of a user and to disable operation when the user is no longer present.
