Description

The invention relates to household appliances, in particular, to a nozzle device that is installed on a hair clipper and can be used in the field of hairdressing as a universal accessory for any type of hair clipper.

The use of nozzles on hair clippers allows you to create popular with young people options for haircuts with a fixed hair length or to create options for patterns on the temples or nape.

The removable nozzle of a hair clipper is known from the prior art, the technical solution of which is disclosed in the published application for invention RU No. 2007126418 A dated 01/20/2009. The nozzle is made with the possibility of connecting it to the body of the hair clipper and has a forming support surface on the skin and a window for indicating the height of cutting, which is associated with the digital display scale.

Also known is the nozzle of the hair clipper, which is described in the patent for utility model RU No. 169198 U, op. 03/09/2017, "Nozzle for cutting the cut ends of long hair" and adopted by the applicant as an analogue of the prototype. The specified nozzle contains a platform (case) with two lateral protruding parallel plates between which the clamping axis is fixed, a bed (clamping plate) with hair dividers in the front part, having in the middle part a protrusion located between the body and the clamping axis, pivotally connected to the body and located with a gap between them to pass the hair strands in the direction from the body towards the hair separator, while the bed is equipped with additional hair dividers in the back, the said protrusion is made in the form rectangular plate with oval-shaped peak, the top of which, laterally arranged notches, and the platform is configured to slide for a removable fastener for mounting the nozzle on the blade unit hair clipper.

The disadvantages of the above nozzles are: cutting the hair from the bottom to the top only along the vertical axis, getting a cut of hair of a constant height, when cutting hair it is impossible to make a smooth transition from short to long hair, it is impossible to control the cut simultaneously in horizontal and vertical planes to achieve a given size cutting height in millimeters, you need to use several nozzles, and of different sizes, in addition, each nozzle works in a set only with the types defined for it and types of hair clippers, and the haircut is at least an hour.

The task in the development of the nozzle is to create a universal nozzle with increased energy efficiency, in terms of using it for all types and types of hair clippers, to ensure a smooth transition from short to long hair when cutting hair, the possibility of obtaining an “oblique” hair cut and expanding the range of Hairstyles options and haircuts and the possibility of reducing the time of haircuts to 20-40 minutes. The technical results of the claimed nozzle are to ensure a smooth transition from short to long hair when cutting hair, to perform the necessary hair cut, to ensure hair cut with simultaneous control of hair cuts in horizontal and vertical planes, to prevent shredded hair from getting into the airways of the hairdresser and client, as well as to reduce time haircuts hair. These technical results are achieved in that the nozzle of the hair clipper containing the movable bed and the platform is additionally equipped with a fork lever made with protrusions on the inside and a shank with a half ring, a spring-type latch installed inside the platform, an emphasis, a coil spring and prongs , while the bed of the nozzle is made with the possibility of installing a hair clipper on it, the platform is made with protrusions and curly holes on the inner sides, and the bed with holes To the protrusions of the platform with grooves, the fork lever has a rotation axis coaxial with the holes made in the platform, and is mounted to move the said protrusions on its inner side along the counter radius hole of the platform and an oval hole in the bed, and the bed from the outside, below the oval hole, is made with recesses that end with protrusions, coil springs are located in the said recesses with the lower plane resting on the protrusions of the bed, and the upper plane - on the protrusions of the platform, which Single provided with recesses with the springs disposed therein and a notch on a toothed rear side.

The proposed nozzle works as follows.

The nozzle consists of a movable bed 1 with a comb (pos. Not indicated), a fixed platform 2, a fork lever 3 with projections 10 on the inside and a shank 18 with a half ring 21, a spring-type latch 5 installed inside the platform 2, a stop 19, a coil spring 22 and the tooth protrusion 20 in its lower part.

Bed 1 is intended for installation in it of the body 4 of the hair clipper with fixation by means of a latch 5 of a spring type. In the nozzle, the bed 1 is mounted inside the platform 2, and in the process of cutting the hair, the bed in the platform moves in the vertical direction. Such a movement of the bed is ensured by the presence of protrusions 6 of the platform, made on its inner sides, corresponding to the protrusions of the platform 2, grooves 7 of the bed 1, fork lever 3, which has an axis of rotation 8, coaxial with the axial holes 9 of the platform 2. The protrusions 10 of the fork also contribute to the movement of the bed 1 the lever 3, made on its inner side, which "go" along the figured hole 11 of the platform 2 and the oval hole 12 in the movable bed 1. When the fork lever 3 moves around the axis 8, its inner protrusions 10 act on the upper or lower plates the oval holes 12 of the bed 1 and raise or lower it inside the platform 2, depending on the direction of rotation of the fork lever 3 around the axis 8. Response to the protrusions of the platform grooves 7 in the bed 1 and the figured holes 11 in the platform 2 determine the range of movement of the bed 1 in the vertical direction .

The bed 1 from its outer side, below the mating grooves 7 has recesses 13, which end with protrusions 14. In the recesses 13 are coil springs 15, which contact the protrusions 14 of the box 1 with the lower part of the turns and the protrusions 6 of the platform 1 with the upper part.

With the vertical movement of the stock 1, the springs 15 are compressed and, in the extreme upper position of the stock 1, the coil springs 15 are in a compressed state. When the stock 1 moves from the upper position to the lower, coil springs 15 are unclenched and push the bed 1 down. The fixed platform 2 has recesses 16, which are similar in shape and arrangement to the recesses 13 of the bed 1, in which the coil springs 15 are located. In the back of the platform 2 has a gear notch 17.

After installing the body 4 of the machine for cutting hair into the nozzle and fixing the last latch 5 of the spring type, the hairdresser takes the machine in his hand, while the body 4 of the machine is located in the hollow between the thumb and forefinger. The hairdresser introduces the index or middle finger of the brush into the hole formed by the shank 18 and the movable half ring 21 of the fork lever 3.

Further, pressing the finger to the brush or pushing it, the hairdresser rotates the fork lever 3 around the axis 8, while raising or lowering the bed 1 inside the platform 2. To prevent spontaneous lowering of the bed 1 under the action of coil springs 15, the nozzle has a fixation of the position of the bed 1 on a certain height relative to the lower plane of the platform 2. The position of the bed is fixed by a stop 19 installed inside the fork lever 3, teeth-protrusions 20 made in the lower part of the fork lever 3, a coil spring 22 and cog that notch 17 in the back of the platform 2.

The stop 19 of the fork lever 3 is spring-loaded with a cylindrical spring 22. The latter abuts against the stop 19 on one side and the fork lever 3 on the other side, the spring 22 being connected to the movable half ring 21. In the released state, the spring 22 pushes the stop 19 forward, and it has teeth 20 falls into the serrated notches 17. Thus, the position of the bed 1 is fixed at the desired height relative to the lower plane of the platform 2, that is, at the desired height of the hair cut. The fixing step is directly dependent on the distance between the recesses of the serrated notch 17. To defocus the bed and move it up or down, the hairdresser pulls the half ring 21 with the index or middle finger of the hand, thereby removing the teeth-protrusions 20 from engagement with the serrated notch 17, compresses the spring 22 and releases the fork lever 3 for free movement about the axis 8. To re-fix the bed 1, the hairdresser releases the half ring 21, and it together with the stop 19 connected to it, under the action of the previously compressed spring 22 d moves forward and introduces the tooth-protrusion 20 into engagement with the gear notch 17.
