PATENT OFFICE

The present invention relates to a portable apparatus for the generation and delivery of Formaldehyde for disinfection purposes. The apparatus is especially for household use pathological disorders in the nasal and respiratory tracts and can easily, even in your pocket, to be carried around. The formaldehyde production is extremely strong, there the atmospheric air before its mixing with the vapors as opposed to that already known apparatus is performed so that a good heating of the same by the the heat released by the process of oxidation is obtained, and indeed without this Ways premature mixing of the atmospheric air with the alcohol vapors takes place.

The attached drawing shows:

Fig. Ι a section through the apparatus.

Fig. 2 shows a side view during the filling process.

Fig. 3 shows the apparatus enclosed in a container.

Fig. 4 is a top view.

The outer container 1, e.g. B. an ordinary water glass, takes the frustoconical, above with a flange 2 ^a resting, the wick tube piece 2 * receiving insert 2 below. In the latter an also conical, provided with air holes, top and bottom open insert 8 is again bent by a right angle to the Flantsch i ^a, provided with air holes 80 Flantsches 8 ^a hooked. Above the insert 8 there is arranged an attachment ring 8 ^C provided with slots 8 /, which is covered by a dome 10 provided ^{with corresponding slots io c} and button io ^e. The latter is attached to a flange io ^a resting on the flange 8 ^a and provided with air holes io ^fe . By rotating the dome, the various air holes can be closed more or less or completely. The various flanges are easily detachably connected to one another by overlapping fingers 8 ^, 8 ^e. In the insert 8, a platinum-plated disc 9 provided with air channels is arranged.

The whole apparatus can be put into a container for the purpose of transport, as can be seen in FIG. can be used.

The apparatus is operated in the following manner.

Methyl alcohol is poured into the container 1, sucked up through the wick 7 and ignited within the insert 2. All air holes are to be kept open, as can be seen in FIG. 1. As soon as the platinum-coated disk 9 is brought to the glowing heat, which can easily be observed through the air holes, all air holes are opened by turning the dome
and thereby suffocate the flame.

The dome is now turned back again so that the air holes are open and produced the lamp then continues to formaldehyde vapors, the incoming air being well preheated through the wall of the insert 8 until the supply of methyl alcohol is exhausted, or until the dome is turned the outside air is shut off again. Due to the annular space between the exterior

closed

container ι and insert 2 a Heifswerden of the container 1 is prevented.

Claims (2)

Patent Claims: 1. Apparatus with adjustable air inlet openings for generating formaldehyde, characterized by a space formed between the insert 8 and the insert 2 in which the air entering through the air holes 8s and required for aldehyde formation is caused by the heat released during the oxidation in the insert 8 is preheated. 2. Embodiment of the apparatus according to claim i, consisting of two preferably frustoconical inserts 2 and 8, the outer insert 2 rests on the edge of the container receiving the methyl alcohol and in the base plate a wick mouthpiece 2 * carries, and the inner one, open at the bottom and inside with a platinized disc 9 provided insert 8 by means of a flange 8 ^a provided with air holes 8 ^ arranged rotatably on the flange i ^{a of} the insert 2 and from a provided with slots io ^e and over the attachment ring 8 ^C , which has corresponding slots, and pushed by means of an with air holes \ o ^h provided bent Flantsches io "rotatably arranged Dom is covered 10th 1 sheet of drawings.
