Embodiment Construction

[0044] exist figure 1 and 2 A first embodiment of the handpiece according to the invention is shown in FIG. 2 , which is designated overall with the reference numeral 10 . The handpiece 10 comprises a housing 12 formed from two half-shells 14 , 16 which are connected to each other, preferably screwed or riveted. The handpiece 10 is substantially tubular and has an inlet section 18 and an outlet section 20 , which merge into one another at an angle of the order of 45°.

[0045] On its rear side 22 facing away from the outlet section 20, the inlet section 18 has an inlet 24 into which a feed line 26 leads, which connects the handpiece 10 to a steam injection device (not shown in the figure). , and feed hot water vapor to the handpiece 10 . The feed line 26 comprises a protective hose 28 which is clamped between the two half-shells 14 and 16 and which surrounds an inner hose 30 which conducts steam. The inner hose 30 extends inside the housing 12 as far as the output section ...

Abstract

The invention relates to a handpiece (10) for a steam jet device having a housing (12) which has an inlet (24) for a feed line and an outlet (48) for a discharging line and in which a metering valve (32) is arranged with a valve housing (34), in which a valve body (52) is mounted which can be displaced to and fro linearly in a displacement direction, wherein the valve body is coupled to an actuating member (78) which is held movably on the housing and can be moved by the user counter to the action of a spring force. In order to develop the handpiece in such a way that it makes particularly sensitive metering of the steam discharge possible, it is proposed according to the invention that at least one spring element is arranged laterally next to the valve housing (34), which at least one spring element loads the valve body (52) with a spring force which is oriented parallel to the displacement direction.

Description

technical field [0001] The invention relates to a handpiece for a steam injection device, which has a housing with an inlet for a feed line and an outlet for a discharge line, in which a valve housing is arranged. A metering valve, in which a valve body is supported in a linear reciprocating direction in the direction of displacement, wherein the valve body is connected to an operating mechanism movably held on the housing, and the user can counteract the action of the spring force Move the operating mechanism. Background technique [0002] Handpieces of this type are used, for example, on steam jet devices for cleaning in housework. The steam injection device includes a steam generator with which water vapor can be generated and then fed to the handpiece through a feed line. Use the hand piece to direct the water vapor at the surface to be cleaned. The amount of steam output per unit time can be metered by the user. For this purpose, a metering valve with a linearly dis...
