Definitions

• the hair styling appliance The hair styling appliance
• the present invention relates to a hair styling device with a hand part, a shaped rod connected to the hand part, an evaporator, a tank from which the evaporator can be supplied with evaporating liquid, and a metering device with which the amount of evaporating liquid entering the evaporator can be controlled.
• the tank being movable, preferably axially displaceable in the longitudinal direction of the device, and the metering device being operable by moving the tank.
• DE 100 12 194 A1 and DE 100 12 193 A1 each show, as a hair styling device of the type mentioned at the outset, a steam styling rod, which has a water tank on the front side of the molding rod opposite the hand part, from which water is metered into or onto the metering device via a metering device Evaporator can be brought, so that a burst of steam or a steam flow exits through the shaped rod on the hair wrapped around it.
• the metering device in this case comprises a wick emerging from the tank, which can be moved towards an evaporator surface by pressing the tank into the molding rod and releases water droplets onto the latter.
• the tank is to be pressed in via a deformable membrane, so that water pushes through the wick and is applied to the evaporator in the form of drops. Since this is often more liquid than is to be evaporated, special means must be provided to convey excess liquid from the evaporator chamber back into the tank.
• the present invention is based on the object of creating an improved hair styling device of the type mentioned, which avoids disadvantages of the prior art and further develops the latter in an advantageous manner.
• the handling of the steam function and the associated evaporation liquid tank should preferably be improved. According to the invention, this object is achieved by a hair styling device according to claim 1.
• Preferred embodiments of the invention are the subject of the dependent claims.
• an actuation button is therefore provided on the handpiece, which is connected to the metering device and allows the metering device to be actuated with the hand gripping the handpiece.
• One-hand operation of the device including steam discharge is possible, which considerably facilitates the handling of the device, especially at the back of the head.
• the actuation button located on the handpiece can be used to conveniently control when and how much evaporation liquid gets into the evaporator and steam is discharged from the molded rod.
• the tank is movably mounted and the metering device is actuated by a corresponding movement of the tank.
• the tank is preferably axially displaceable in the longitudinal direction of the device. If the tank is moved into a first end position, liquid can get from the tank into the evaporator and evaporate there. If the tank is moved to a second end position, the liquid supply to the evaporator is interrupted.
• the tank is advantageously arranged on the end section of the shaped rod opposite the hand part. This enables a compact design of the device to be achieved.
• the tank in a further development of the invention is connected via a connecting piece to the actuation button provided on the hand part, so that the tank can be moved via the actuation button and the liquid supply into the evaporator can thus be controlled.
• the connecting piece between the tank and the actuation button serves not only to connect these two components.
• the connecting piece advantageously forms a heat protection cover which covers the heatable shaped rod.
• the connection piece or the heat protection cover can in principle be shaped differently.
• the connecting piece extends in a half-shell shape around or along the shaped rod essentially over its entire length.
• a particularly easy-to-assemble design is achieved in that the tank, the connecting piece and the actuation button are integrally formed in one piece with one another, preferably injection molded from plastic.
• the actuation button for actuating the metering device or for displacing the tank can be arranged at various points on the hand part. According to a particularly favorable arrangement, the actuation button is located at the end of the hand part on the form rod or the transition between the hand part and the form rod in the region of a thumb or index finger of the hand gripping the hand part. If the hair styling device has a jaw that can be swiveled open and closed, with which hair can be pressed onto the stylus, the actuation button for the steam function is preferably located on an actuation button for the side of the device opposite the jaw.
• the tank arranged on the end face of the shaped rod can also be gripped and moved directly in order to cause the liquid to be fed into the evaporator.
• the tank is thus assigned two operating sections, which can be operated with one hand or two hands.
• the control of the liquid supply into the evaporator by moving the tank can be achieved in that the metering device has a wick which passes through a tank wall opposite the evaporator and can be moved by moving the tank towards or away from an evaporator surface. If the wick is moved onto the evaporator surface, liquid is evaporated from the wick. However, if the wick is moved away from the evaporator surface, the generation of steam is prevented.
• the tank can be moved towards the evaporator to such an extent that the protruding wick comes into engagement with the evaporator surface, that is to say it lies directly on it. However, the travel of the tank is preferably limited, so that the wick cannot be pressed excessively onto the evaporator surface.
• the wick is divided into several end sections at its end facing the evaporator surface.
• the wick preferably has an approximately V-shaped fanning out and the evaporator surface has a complementary V-shaped contour so that the wick with the V-shaped fanning out can be moved onto the evaporator surface.
• the wick forming a capillary can be arranged or aligned differently.
• the wick extends eccentrically into the tank, ie it is arranged laterally offset radially to a tank wall. This makes it easier to suck up liquid residues in the tank when the tank is only low.
• the tank can be detachably inserted into the head piece of a heating tube cover, which surrounds the evaporator or delimits an evaporator chamber, wherein it is preferably secured by an elastic locking device.
• the tank wall can have a preferably integrally molded wick guide, which can be inserted axially into an evaporator chamber wall, wherein the latching device is preferably provided between the evaporator chamber wall and the tank, which prevents the tank from slipping out unintentionally, but permits axial movement of the tank.
• the detent lock can be achieved by means of a locking spring which is fixed on the device side and can be snapped onto a protrusion on the tank.
• a U-shaped spring clip can be provided, which can spring open radially, slide over a radial projection provided thereon when the wick guide is inserted, and / or snap into a radial undercut on the wick guide.
• a radial seal is provided in a further development of the invention between the wick guide and the recess in the evaporator chamber wall into which the wick guide is inserted.
• the radial seal is preferably designed such that it allows the wick guide to be axially displaceable and seals in several axial positions of the tank.
• An advantageous embodiment of the invention is that a lip seal is preferably provided with a double lip.
• the tank can be pretensioned into its position preventing the liquid supply by means of a spring device.
• a spring-loaded stamp is provided on the head piece of the heating tube cover, in which the tank is seated with its wick guide, which presses against the tank bottom.
• the movement of the stamp is preferably limited by means of stops.
• the end positions of the spring plunger define the two operating positions of the tank, namely the position that prevents the liquid supply and the position that causes the liquid supply.
• a further development of the invention provides a vent valve for the tank, through which a corresponding amount of air can be returned to the tank when liquid escapes from the tank.
• the vent valve can in principle be provided at various points on the tank. According to a preferred embodiment of the Invention, the vent valve can be installed directly next to the wick guide in the adjacent tank bottom section.
• the tank In order to improve the filling of the tank, the tank has a lid which is covered by a device section when the tank is assembled and can only be accessed or opened when the tank is disassembled. This prevents the entire hair styling device from being held under a tap for filling the tank.
• the tank In order to be able to open the lid, the tank must first be removed from the rest of the device.
• a swivel lid and / or a stopper can be provided as a lid, which allows the tank to be opened easily.
• the entire metering device assembly does not have to be unscrewed from the tank in order to be able to fill it.
• the lid conveniently closes the tank in a liquid-tight manner.
• the lid of the tank can be arranged on a tank lid section which, when the tank is assembled, lies under the clamping jaw which interacts with the shaped rod.
• the tank as a whole can have an approximately crescent-shaped cross section with a flat side on which the tank cap is provided.
• the tank is preferably located with the flat side under the clamping jaw of the device in the half of the device cross section opposite the clamping jaw.
• the radially offset wick can be arranged towards the flat side.

• the hair styling device shown in the figures is a so-called straightener, with which curly or frizzy hair can be pulled straight, but can also be brought into any other desired shape. It is designed as a gas-operated steam styling rod, in which an evaporator is heated by means of a gas burner and generates steam.
• the device has an essentially cylindrical handle 1 on which the device can be gripped.
• a stylus 2 is attached to the face of the hand part 1, with which the hair can be shaped or processed.
• a clamping jaw 3 lies in the shape of a half shell on a lateral surface side of the heated shaped rod 2 and can be pivoted away from the shaped rod 2 by means of a rocker button 4.

• the special arrangement and design of the tank cap 17 ensures two things: On the one hand, the device is prevented from being kept under a tap for filling the tank, since the tank cap can only be opened in the disassembled position of the tank 15. On the other hand, the arrangement of the fuel cap 17 under a cover, which is formed by the clamping jaw 3, prevents the fuel cap 17 from opening unintentionally during operation.
• a metering device 19 is provided between the tank 15 and the evaporator 9, which allows a metered delivery of liquid from the tank to the evaporator.
• the metering device 19 comprises a wick 20 in the form of a folded felt plate, which is accommodated in an axially extending wick guide 21 with a precise fit.
