Description

The field of technology.

The utility model relates to hand-held devices in the field of household appliances such as fans and fans. It serves to create and regulate the air flow in rooms and/or outdoors. The device is intended for blowing users in hot weather, distributing hot steam and cold air in saunas and baths, for fanning fire and dispersing insects.

The level of technology.

There are many designs of fans and fans. In particular, from patent documents CN 205358557 U, 07/06/2016; CN 106263346 A, 01/04/2017; CN 2138416 Y, 07/21/1993; CN 102641028 A, 05/08/2015; JP 2001128717 A, 05/15/2001, which include a frame, mainly of an annular shape, a separate handle, which is attached to the frame with connecting elements, as well as a paper, leather or fabric web, which is attached to the frame.

All these designs consist of many separate structural elements, the presence of which leads to the fact that the resulting product has a fairly significant weight and is very laborious to manufacture.

The fan described in the patent JP 2002142825 A, May 21, 2002 is made in the form of a frame made of a bent element made of plastic, wood or metal, with the formation of a closed annular contour. A cover made of stretchable fabric is put on the formed contour, and the ends of the element are fastened with a grip to form a handle.

The disadvantage of this fan is its insufficient reliability and durability, since the stretchable fabric of the cover stretches over time and loses its properties, which subsequently leads to a loose fit of the cover to the frame and, accordingly, its jumping off the frame with the active use of the fan.

The well-known fan from the patent CN 207220367, 04/13/2018 is made of a ring frame with stiffeners inside it and a handle. A cover in the shape of a semicircle is put on the frame, while the frame with stiffeners and a handle are made of bamboo.

The disadvantages of this device include the significant complexity of the design of the frame, made with stiffeners.

The fan from patent AT 411128 B, 10/27/2003, includes a flexible frame of a drop-shaped closed shape made of spring wire or fiberglass, the ends of which are connected together and inserted into the sleeve, and the internal space of the frame is filled with either leather or fabric, which is dressed on the frame by means of tunnel formed in the canvas by bending its edge.

The disadvantage of this design is the problematic and injury risk of its use in rooms with high temperatures (up to 100°C or more) due to the large weight and the use of metal or glass elements in its design.

One of the analogues is a device according to patent RU 178725 U1, 04/18/2018. This device for manual control of the air flow in the steam room is made in the form of a frame made of an extended bent element made of non-resinous wood species, with the formation of a closed elongated drop-shaped frame contour, in the space of which a woven fabric is placed, made with the possibility of fixing it on the bent element by threading the latter into a through tunnel channel formed in the web by bending its edge, while the ends of the element form a handle for gripping the device by the user and are interconnected by a fastening element made of fibrous material.

The disadvantage of this analog is its lack of reliability and durability, the complexity of manufacturing, and the use of a single woven fabric, which allows the weakening of the pressure of the air flow due to the passage of air through the fabric. The complexity of manufacturing lies in the fact that, according to the analog, it is necessary to form a tunnel channel by turning the edges of the web, and then pushing a frame into this channel, which can damage the ends of the web.

The closest in essence and achieved technical result is the design of the fan, disclosed in the patent RU 205219 U1, 07/05/2021. This device for creating and distributing air flows contains a base of an elastically bent rod, the end parts of which are fastened together by a cord wrapped around them. In the upper part, the device has a rounded shape, which narrows towards the end parts of the rod, fastened together, forming the handle of the device, while the base part is covered by two webs sewn together by a seam outside the outer perimeter of the curved upper part of the rod. At the ends of the rod there are plugs in the form of caps that cover the sharp edges of the ends of the rod.

The disadvantages of the closest analogue are: the danger of sharp edges on the edges of the handle rod; the complexity of manufacturing a cover by sheathing it over an already finished device; fullness of the frame rod, which reduces the rigidity of the structure and increases the weight; fastening the ends of the rod into the handle only with a cord, which, with loosening and damage during operation, leads to a violation of the rigidity and integrity of the entire structure; the inability to remove the woven cover for washing or replacing without damaging it.

Disclosure of the essence of the utility model.

The technical problem to be solved by the device is the elimination of the listed shortcomings of the closest analogue. The technical result is to increase the strength and, as a consequence, the reliability and durability of the device; weight reduction and, as a result, ease of use.

The technical result is achieved as follows. The device for creating and distributing air flows contains a frame made of a hollow rod elastically bent into a teardrop shape with partitions (1). Such a rod makes the frame more rigid with significantly less weight than a solid rod of the closest analogue. This provides a more comfortable application, especially during prolonged use (waving) and gives greater strength to the entire device. The ends of the rod (2) are machined from sharp edges and fastened together with polymer clamps/tapes (3), forming the handle of the device (5). Finishing the ends from sharp corners makes the product safer and eliminates the need for caps. A cord (4) is tightly wound around the handle with a loop at the end so that you can hang the device. Clamps ensure that the handle of the device is not likely to fall apart and / or loosen in case of damage, spreading or stretching of the cord. They also make it possible to replace the cord after it is worn out without violating the integrity of the device design. A cover (6) made of two identical teardrop-shaped sheets connected to each other by a zipper (7) is tightly put on a large part of the frame from the wide side. It is much easier to make such a cover than to sheathe a finished device. It is easy to remove for washing or replace if necessary, unlike the impossibility of doing this with a close analogue.

The device is illustrated by drawings. On FIG. 1 shows a rod with partitions (1), bent into a teardrop shape, with the ends (2) fastened with bands/clamps (3). On FIG. 2 shows a cover (6) made of two identical drop-shaped sheets connected to each other by a zipper (7). On FIG. 3 shows the finished device with a cord (4) wound around the ends of the rod to shape the handle (5).

Implementation of the utility model.

The device is made as follows: A hollow rod with partitions (1), mainly from a bamboo trunk, is elastically (without kinks) bent into an appropriate teardrop shape. The ends of the rod (2) are placed parallel to each other or slightly overlapped, fastening them together with two polymer clamps/tapes (3), forming the handle of the device (5) and giving a general shape to the frame in the form of a tennis racket. A cord (4) is tightly wound around the handle with a loop at the end so that you can hang the device. Next, a separately made cover is taken from two identical drop-shaped canvases (6) connected by a zipper (7), and is put on the frame by threading the latter through the zipper opening with the handle forward. The zipper closes - the product is ready.

The device works as follows. The proposed device is designed to create an air flow and/or to evenly distribute air in a closed room, such as hot steam and cold air in a steam room or sauna. To create an air flow, the device perform reciprocating movements in space with the hands of one or both hands, holding the device by the handle (4). Thanks to the put on cover, moving in space, the device creates an air flow, since air is not passed through it.
