Abstract

The invention relates to means for human hygiene, and in part to designs of shaving devices intended for mechanical hair removal. The present electric shaver with a cylindrical cutting unit consists of a housing, in which are provided an electric drive and an AAA-type battery, an on/off pushbutton, a hermetic cap and a rod, round plate-like blades which are fixedly secured to the rod, a hollow mesh tube and a movable rotating support segment. The rod having the round plate-like blades secured thereto is positioned inside the hollow mesh tube and is rigidly affixed at one end to the reciprocating electric drive, while the other end of the rod is free and unsecured; one side of the hollow mesh tube is provided with apertures of a normal diameter, while the other side is provided with apertures of a larger diameter. In order to prevent the likelihood of transverse deformation of the cylindrical cutting unit during shaving, a movable rotating support segment is installed on the shaver housing.

Description

 Description of the invention

Electric Shaver with Cylindrical Cutting Block

The invention relates to human hygiene, in particular, the design of shaving devices designed to remove hair mechanically.

Known is an electromechanical mesh-type shaving device, the design of which consists of a cutting mechanism (knife block) with comb knives that perform reciprocating movements and a U-like mesh knife, an analogue (in the way of use) which is currently commercially available from PANASONIC- (ES3042) -

(http://www.panasonic.ua/products/health_beauty/mens_care/ shaver / ES3042S503) or a rotary-type electromechanical shaving device, the design of which consists of a cutting mechanism (knife block) with round knives that rotate and round mesh knife, the analogue (in the way of use) of which is also currently commercially available by PHILIPS- (АТ890) - (http://www.philips.Ua/c/mens-shaving/aquatouch-dualprecision-blades-flexing-heads-at890_16 / prd /),

 electric drive and housing.

 The disadvantage of these electromechanical devices is that the existing models have large enough overall dimensions, mainly depending on the AC source, high cost, short life of mesh knives, design complexity, a large number of mechanical structural elements and, mainly, the inability to use them simultaneously dry and wet shaving.

 The closest to the claimed invention in terms of essential features there is an analogue to the document

 CN 203156794 U dated 08/28/2013 .; which also has a cylindrical cutting element in its design (a hollow mesh tube and a rod with round plate knives fixed on it). The main disadvantage of these devices and the closest analogue of the document

 CN 203156794 U dated 08/28/2013 there is an imperfection and cumbersome design, which entails complexity and complexity in production and inconvenience in

 use.

 The main task of the invention is to change the design of the cutting knives and the design of the cutting unit

shaving electromechanical device in order to reduce overall dimensions, reduce the cost of production and assembly of the device, giving the device a convenient and aesthetic appearance.

The task that was set is solved in such a way that in the electromechanical shaving device, in the design of which there is a mechanism for cutting with knives, the new is that

 the design of the cutting mechanism (knife block) is made in the form of a hollow mesh tube, in which round plate knives are fixedly fixed on the rigid rod, which, with the help of an electric drive, perform a quick reciprocating movement together with the rod, which on the other is free and loose and is supported by movable rotational support segment.

This form of the cutting mechanism (knife block) makes it possible to reduce the dimensions of the shaving device to almost the diameter of an AAA battery, use the device for both dry and wet shaving, significantly reduce the cost of manufacturing and assembling the device, increase reliability and convenience of the device due to the simplicity of design. Also, an important feature of this device is that one side of the hollow mesh tube is made with

 holes of the usual diameter (0, 1 mm), and the other with holes of a larger diameter (0.3 mm), which will allow shaving longer hair without additional effort and time, and shaving through the holes of the movable rotational support segment will allow you to leave after shaving on the area of skin that shaves, the hair is the same length. When performing construction

 an electric razor with a cylindrical cutting unit sealed in places of detachable connection, a power button and a place of contact of a movable element (rod) with the body, there is a possibility

 use of the device when completely immersed in water.

The technical essence of the proposed electric razor with a cylindrical cutting unit is explained by drawings, in which:

 9. AAA battery

 An electric razor with a cylindrical cutting block consists of a housing 4, in which a reciprocating electric drive 8 and an AAA 9 type battery, a power on / off push button 3, an airtight cover 5, which is attached to the housing 4 and is designed to protect the electric actuator, are located - progressive

movement 8 and the battery type AAA 9 from moisture and other foreign objects and substances, as well as for charging or replacing spent batteries type AAA 9, rod 6, which is connected to the electric drive back and forth movement 8 and to which it is transmitted back and forth movement electric drive 8, fixedly mounted on the stem 6 of circular plate knives 7, which are placed inside a hollow mesh tube with holes of different diameters 1 and a movable rotational support segment 2, which rotates around axis of the cutting unit and the housing 4 and is designed to prevent lateral deformation of the cylindrical cutting unit which can occur when excessive pressed against the cutting unit to the cylindrical body portion, which shaves.

 Electric razor with a cylindrical cutting unit operates as follows. A nominally charged AAA 9 type battery is installed in the housing 4 in compliance with the polarity and is closed by a sealed cover 5. The stem 6 with the circular blade knives 7 fixed on it is rigidly attached to

 reciprocating electric drive 8. Hollow mesh tube with holes of different diameters by screwing or in some other way

 attached to the housing 4 in such a way that the stem 6 with the circular blade knives 7 fixed on it are located inside the hollow mesh tube with holes of different diameters 1. The movable rotational support segment 2 is connected to the housing 4 using a quick movable locking mechanism (for example, groove). By pressing the push button

power on / off 3 voltage from the AAA 9 type battery is supplied to the electric drive 8 - reciprocating, which in turn gives reciprocating movement of the stem 6 with the circular plate knives fixed on it 7. The hair that falls into the holes of the hollow mesh tube with holes of different diameters 1 is cut off with round plate knives 7 due to the tight contact of the walls of the hollow mesh tube with holes of different diameters 1 s the cutting surfaces of round plate knives 7. After the shaving process is completed, the movable rotational support segment 2 is removed from the body 4, then

hollow mesh tube with holes of different diameters 1 is disconnected from the electric shaver body 4, rod 6 s

motionless fixed on it round plate knives 7 are disconnected from the electric drive reciprocating movement 8 and are washed under a stream of water to clean the dirt from the remnants of the foam and hair.
