Abstract

Use: clean the walls of the aquarium. SUMMARY OF THE INVENTION: The device comprises a holder and a scraper in the form of an elastic sucker with a cylindrical internal cavity and an annular protrusion on the inner edge of the working surface of the scraper, the efficiency of which is enhanced by rarefaction in the internal cavity. 1 il.

Description

The invention relates to aquarium fish farming, in particular, to means for cleaning the inner surface of the walls of amateur aquariums designed to contain, breed and display aquatic organisms,

Aquariums of the standard type, rectangular of ordinary glass in a metal frame or solid organic glass, have now found the most common.

To saturate the water with oxygen, aquatic plants are placed in the aquarium and illuminated for several hours a day. Plants in the light absorb carbon dioxide emitted by aquarium fish, and give up oxygen. At the same time, they absorb organic and inorganic substances from water. With the correct ratio of the number of aquatic organisms in the aquarium, a biological equilibrium is created, at which a change of water and aeration are even harmful. It is enough from time to time to add to the aquarium the settled water to replace the evaporated water, remove accumulated sediments at the bottom and periodically clean the inner walls of the aquarium from contamination. This can be done with the help of sand, gauze, foam sponge, etc.

However, the use of a tampon made of foam rubber and other listed materials does not provide effective quality cleaning of the walls of the aquarium, since plaque on the walls is formed mainly by green and brown microalgae that have strong adhesion to the surface of the glass and which cannot be cleaned with soft materials. Therefore, for a more efficient cleaning, a razor blade inserted into a special long-handled mandrel is used.

The disadvantage of such a device is that it must be pressed against the walls when it is moved during cleaning, which is not very convenient, since the quality of cleaning from uneven pressure is reduced. In addition, a blade tool cannot be effectively used in view of possible damage to the cleaning surface and for cleaning artificial glass aquariums.

Along with the listed cleaning agents, an aquarium cleaning device is known which consists of a suction tube which acts as a holder,

a tapered nozzle fitted with an elastic tapered suction cup having an outer edge that acts as a scraper when the device is moved along the wall of the aquarium. To remove scrape discs, the suction cup is located coaxially with a nozzle to form a gap communicating with the tube.

The said device can be used to clean the vertical walls of amateur aquariums from both normal and plexiglass without applying forced pressure on the walls by the person performing the cleaning,

However, since the plaque formed on the inner walls of the aquarium consists mainly of hard-to-clean microalgae with strong adhesion to the glass, and the suction scraper has only an external scrubbing edge that slips during the cleaning process on the remaining cut algae, the required quality of cleaning (complete removal of plaque to transparency aquarium walls) is not reached. Due to this drawback, the known device can be used in conjunction with the blade tool described above to achieve a high-quality cleaning.

The purpose of the invention is to improve the quality of cleaning.

This is achieved by the fact that in the device containing the holder with a scraper in the form of an elastic suction cup, having an internal cavity and an annular working surface, the inner edge of the working surface has an annular protrusion located in the internal cavity of the suction cup, and to facilitate the collection and removal of contaminants the internal cavity is made in the form of a cylinder.

The drawing shows the device section.

The device consists of a removable suction cup 1 with an annular working surface and made of elastic material, a holder 2 with a handle 3. The suction cup 1 contains an outer 4 and an inner 5 edge to scrape dirt. Edge 5 has an annular protrusion 6 located along the inner cavity 7 forming a vacuum chamber. In addition, the cavity 7, together with the protrusion 6, is designed to receive and maintain scraped deposits for the period of cleaning and has the shape of a cylinder. On top of the suction cup 1 is covered with a decorative cap 8,

The cleaning of the aquarium is performed as follows.

The working surface of the sucker 1 is moistened with water, perch it in the water of the aquarium,

applied to the surface of the wall from the inside of the aquarium and pressed against it. When pressing the suction cup 1 is deformed, the internal volume of its cavity 7

decreases and at the same time most of the air is displaced into the atmosphere. Upon termination of the force action, the sucker 1, under the action of elastic forces, tries to regain its original shape. Interior

0, the volume increases, the air pressure in it decreases, and with atmospheric pressure the sucker presses against the wall of the aquarium and is held in this position. The outer 4 and inner 5 edges, being in the stressed state, are sufficiently rigid to perform the function of the scraper. Using the holder 2 with the handle 3, the sucker 1 is inserted into the underwater part of the aquarium and in smooth movements.

0 is moved in different directions, observing through the glass of the aquarium the process of cleaning and the accumulation in the cavity 7 of the scrape scratched from the walls. Cleaning is carried out continuously in water, which prevents atmospheric air from entering the cavity 7 of the suction cup 1, which contributes to the stability of the suction cup 1 against the wall of the aquarium. During the cleaning process, the annular protrusion 6, carrying the edge 5 and located in cavity 7, is surrounded by a low pressure area, which ensures that the inner edge 5 is pressed against the surface to be cleaned regardless of filling the cavity 7 with cleanings and facilitates detachment of microalgae from the walls of the aquarium . The protrusion 6 can also serve as a means indicating that the cavity 7 of the sucker 1 has to be emptied.

0At the end of cleaning one of the walls

the aquarium or, if the protrusion 6 is exceeded by scraped deposits, the suction cup 1 is pulled into the aquarium top part and, lifting the outer edge 4, provides 5 access of the atmospheric air into the cavity 7 of the suction cup 1 and removes the device from the aquarium, while the annular protrusion 6 ensures that the scraped mass is retained knowledge in cavity 7 until its emptying. After clearing cavity 7 from collected sediments, the device is again ready to continue cleaning.

The device for cleaning the walls of the aquarium is simple in design, inexpensive to manufacture, and ensures reliable, fast and high-quality cleaning of the walls without disturbing the biological balance established earlier in the aquarium. The collected sediments (microalgae) can be dried and used as an additive in

dry food for fish. In view of the removable design, the suction cup can be used as a suction holder for various items in the aquarium. In the inner cavity of the suction cup, a swab made of foam rubber or other porous material can be placed, fixed between the annular protrusion and the bottom of the suction cup. Claim 1. Device for cleaning the walls of an aquarium containing a holder with a scraper attached to it in the form of an elastic 0 suction cups with an internal cavity forming a vacuum chamber and an annular working surface, on the outer edge of which there is an annular protrusion, characterized in that, in order to improve the quality of cleaning, the inner edge of the working surface also has an annular protrusion. 2.
