Description

A utility model is claimed - a portable device for boiling water, which can be used, for example, as a tourist or camping equipment. Such a device can be used in extreme conditions, since dry fuel is used as a heat source for boiling a liquid.

Primitive devices for heating a liquid are known, for example, an alcohol lamp. This is a device that allows you to boil a small amount of liquid in a vessel, while burning a certain amount of alcohol in a closed flask. An open flame is used in the spirit lamp, which is extremely uneconomical.

It is a well-known tourist device manufactured by our industry, which allows you to heat a small amount of liquid using dry fuel. This device contains a combustion chamber into which dry fuel is placed and into which a container with liquid is inserted. However, this device is inconvenient for use, since it is a tall narrow can into which it is inconvenient to insert and remove a container of water.

The closest is a device for boiling water (certificate of the Russian Federation for utility model No. 5844 of 11/05/96). The device comprises a combustion chamber consisting of two parts, the outer part of the chamber having a larger diameter than the inner one, and a flask for accommodating the vessel with the liquid. The flask is made with the possibility of fixation in the upper part of the outer chamber and has a diameter exceeding the diameter of this chamber. This device is not convenient enough and safe when using it.

The inventive portable device for boiling water, as well as known, also contains a combustion chamber consisting of two parts, the outer part of the chamber having a larger diameter than the inner one, and a flask for accommodating a vessel with liquid, made with the possibility

fixation in the upper part of the outer chamber and having a diameter greater than the diameter of this chamber.

The problem solved by this utility model was to increase the convenience and safety of using the device.

The technical result, which consists in increasing the safety and economy of the consumption of dry fuel, is achieved by the fact that on the upper part of the outer chamber there are four hook-shaped protrusions located inwardly opposite each other, segmental protrusions made towards the outer chamber are made on the upper part of the internal combustion chamber. In the lower part of the outer chamber, a door is fixed that covers the hole for filling the fuel. The flask is made with a deep slot and with two holes coaxially located in its upper part.

The execution on the upper part of the outer chamber of four hook-shaped protrusions located inward against each other, provides a reliable installation of the vessel with the liquid, which increases the convenience and safety when using the device.

Performing on the upper part of the internal combustion chamber of segmental protrusions, deployed towards the outer chamber, provides directional distribution of the flame gas flow, which contributes to the economical consumption of fuel.

The fastening in the lower part of the outer chamber of the door covering the hole for filling the fuel provides regulation of the air supply to the combustion chamber and protection of the flame from blowing by the wind, which also increases the economy of dry fuel consumption.

The implementation of the flask with a deep slot ensures reliable fastening of the handle of the vessel with liquid (for example, mugs) in the device, which increases the convenience and safety of using the device.

The implementation of the flask with two holes coaxially located in its upper part, provides suspension of the device in case

the impossibility of installing it on the ground or on another supporting surface, which increases the convenience when using the device.

The inventive device is illustrated using the drawings, where Fig. 1 is a side view of a portable device for boiling water, and Fig. 2 is a top view of a portable device.

The portable device contains a bulb 1 shaped and a combustion chamber consisting of an outer 2 and an inner 3 chambers. On the upper part of the outer chamber 2 there are four hook-shaped protrusions 4 located inward against each other. On the upper part of the internal combustion chamber 3, segmental protrusions 5 are made, deployed in the direction of the outer chamber 2. In the lower part of the outer chamber 2, a door 6 is fixed, covering the hole for filling the fuel (not shown in the drawing). The door 6 can be fixed, for example, on the hinges 7 or in another way of fastening. On the side opposite the door 6 of the bottom of the outer chamber 2, a slot 8 is made for additional air supply and removal of the flame from the walls of the combustion chamber. The base 9 of the outer combustion chamber 2 is connected to the base (not shown) of the inner combustion chamber 3, for example, with a rivet or bolt (not shown). The combustion chamber is made of non-combustible material.

The flask 1 is made with a deep slot 10 and with two holes 11, coaxially located in its upper part. In the lower part of the flask 1, a small slot 12 is made for fixing the flask 1 on the external combustion chamber 2 using a clamp (not shown in the drawing).

Overall dimensions of the portable device in assembled form:

diameter - up to 100 mm, height - up to 130 mm, but the device can be manufactured in other sizes.

The device is stored and transported assembled and used as follows.

The bulb 1 rises up the outer chamber 2 and is fixed in the upper position by a latch. Opening the door 6 through the hole in the inner chamber

combustion 3, a dry fuel tablet is laid and set on fire. The door is left ajar. A vessel with liquid, for example, a mug, is mounted on hook-shaped protrusions 4 of the outer chamber 2, while the handle of the mug is lowered into the slot 10 of the flask 1. For faster boiling, the mug is covered with a lid. To boil a mug of water in the summer, 1 tablet is enough, in the winter - 1.5 tablets.

At the end of boiling, the mug is removed from the device by the handle (the handle can be wrapped with adhesive tape, electrical tape or other materials, or you can use a tack, rag). After cooling, the device is assembled in the reverse order, the mug can be inserted into the flask 1 with the bottom up. The device is compact, easily extends and folds.

Such a portable device can be easily manufactured at home and in the conditions of any mechanical plant, does not require expensive materials, is convenient and safe to use, economical and compact.
