Description

The utility model relates to devices for spraying aerosol cans (aerosol cans can be of different types) and can be used in the medical and construction fields for painting and varnish work.

The most popular area of application of the proposed device for semi-automatic spraying of aerosol cans is the generation of a test signal for online operational remote monitoring of the performance of fire smoke detectors. The maximum accuracy and reliability of testing fire smoke detectors is shown by the so-called functional test. A functional test is usually understood as checking the operation of a detector using chemical, physical or combined effects on a special measurement chamber or sensitive element of the detector. To test smoke and gas detectors, a special device containing an aerosol is used. This device is used to spray aerosol cans containing a smoke simulator and/or carbon monoxide directly onto a smoke detector. When testing, the problem of access to the detector often arises, since it may be located in a hard-to-reach place, for example, when testing smoke detectors located in industrial premises with high ceilings. In this case, aerosol spray devices mounted on a telescopic rod are used, which significantly simplifies and speeds up the inspection process “from the floor,” reducing work at height, and reducing the cost of using lifting structures.

The technical problem to be solved by the claimed utility model is the creation of a simple design of a device for semi-automatic spraying of aerosol cans, ensuring ease of use.

The technical result is achieved due to the inventive design of a device for spraying aerosol cans, containing a lid and a base connected to each other using a tongue-and-groove connection,

wherein the base is made in the form of a hollow cylinder,

and the lid is made in the form of two hollow coaxial cylinders of different diameters and a central hole made on the side of the smaller cylinder,

and is equipped with a movable starting lever, consisting of two movable plates, located stepwise one above the other between two fastening plates, which are integral with the cover,

in this case, the movable and fastening plates are secured to each other using a bolted connection,

the movable trigger lever is equipped with a trigger element made in the form of a hollow parallelepiped and located above the central hole in the cover.

L-shaped grooves can be made on the outer side surface of the base, located symmetrically opposite each other relative to the axis of symmetry of the base.

The device can be equipped with a fastening element made in the form of a parallelepiped, with at least one eye and located on the outer surface of the base.

Fig. 7 shows a photograph of the spraying device assembled with an inserted aerosol can.

A device for spraying aerosol cans contains a cover 1 and a base 2, into which an aerosol can 3 is installed. The cover 1 and the base 2 are connected to each other using a tongue-and-groove connection. On the outer side surface of the base 2 there are L-shaped grooves 4 located symmetrically opposite each other relative to the axis of symmetry of the base. Cover 1 is made in the form of two hollow coaxial cylinders of different diameters and with a central hole. On the inner surface of the cover 1, protrusions 5 are located symmetrically relative to its axis of symmetry. When connecting the cover 1 with the base 2 to each other, the protrusions 5 enter the L-shaped grooves 4 of the base 2, thereby forming a tongue-and-groove connection. Then the cover 1 is turned so that the protrusions 5 are in the horizontal part of the L-shaped grooves 4, thereby achieving high tightness and reliability of the connection between the cover and the base.

The cover 1 is equipped with a movable trigger lever, consisting of the first 6 and second 7 movable plates, installed in stages: the first movable plate 6 is installed above the second 7 movable plate. The first 6 and second 7 movable plates are located between the fastening plates 5, which are one piece with the cover 1. The first 6 and second 7 movable plates and the fastening plates 5 are secured to each other using a bolted connection with a gap with the possibility of free upward and downward movement of the movable plates 6 and 7. The bolts are installed in coaxial holes 9 in the movable plates 6 and 7 and in the fastening plates 8. It is preferable to use self-locking nuts to create a more reliable connection between the movable and fastening plates.

The movable trigger lever is equipped with a trigger element 10, made in the form of a hollow parallelepiped and located at the end of the first movable plate 6, located above the central hole in the cover 1. It is preferable to position the trigger element 10 at an angle to the first movable plate 6 for more efficient spraying due to complete contact starting element 10 to the spray head of the aerosol can 3.

The device is equipped with a fastening element 11, made in the form of a parallelepiped, with at least one eye 12 and located on the outer side surface of the base 1. The fastening element 11 is used for fastening the device for spraying aerosols on a rod using harnesses and is used if it is necessary to spray aerosols cylinders in hard-to-reach and high-lying places when testing smoke detectors. The fastening element 11 can be made with a curved outer surface to ensure a tighter fit of the base 2 to the rod. It is preferable to have two eyes 12 on the fastening element 11 to ensure more reliable fixation of the device on the rod. All components of the proposed device can be manufactured using 3D printing from polymers, for example, PLA, ABS.

The device for spraying aerosol cans operates as follows.

An aerosol can 3 is installed in the base 2, then covered with a lid 1 and the lid is screwed on so that the protrusions 5 are in the horizontal part of the L-shaped grooves 4. The can is sprayed as follows. The user lowers the movable trigger lever down by pressing the protruding end of the second movable plate 7, due to which the part of the first movable plate 6 in contact with it tends upward, and the other end of the first movable plate 6, equipped with the trigger element 10, moves downward, resulting in pressure ( pressing) on the spray head of the cylinder 3.

If it is necessary to spray an aerosol in hard-to-reach places, for example, when checking smoke detectors located on the ceiling, the base 2 is secured to a telescopic rod using clamps threaded through the eyes 12 on the fastening element 11. The convex surface of the fastening element 11 ensures a tight fit of the base 2 to the rod . A fishing line is threaded into a hole previously made in the protruding end of the second movable plate 7. The other end of the line can be attached to the other end of the rod in the reel. Pressing on the spray head of the cylinder occurs in a similar way due to the tension of the fishing line as it is wound in the reel.
