Shaving system

Abstract

The invention relates to shaving systems containing a handle and replaceable cartridges and allowing a liquid to be supplied to the skin of the user during use. A shaving system comprises a handle (1) having an internal channel (2) for passing liquid; an adapter head (3) on the proximal end of the handle (1), having a slot-type channel (4) which communicates with the channel (2) of the handle (1); a cartridge holder (5) in the form of a floating arm which has an internal slot-type channel (6) and is disposed on the proximal end of the head (3), said slot-type channel communicating with the slot-type channel (4) of the head (3); a replaceable cartridge (7) and an adapter (8) connected to a liquid supply and having an internal channel (9) for passing liquid. The connections between adapter (8) and handle (1), handle (1) and head (3), and head (3) and cartridge holder (5) are made detachable by means of a pin/plug connection. The result is an improved quality of shaving and rinsing of the shaver, as well as reduced design complexity.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention is illustrated by the drawings, where:

(2) FIG. 1 shows a longitudinal section of the device assembly;

(3) FIG. 2 shows an exploded view of the shaving system of FIG. 1; and

(4) FIG. 3 shows a section of the attachment with a toothbrush.

DETAILED DESCRIPTION

(5) Referring now to the drawings, in a preferred embodiment of the disclosure, the shaving system includes a handle (1) with an inner channel (2) for passing liquid having proximal and distal ends; head (3) at the proximal end of the handle (1) with a slot-type channel (4) interconnected with the channel (2) of the handle (1); a cartridge holder (5) in the form of a floating arm with an inner slot-type channel (6) at the proximal end of the head (3) and interconnected with the slot-type channel (4) of the head (3); a removable cartridge (7) and adapter (8) connected to the liquid source with an inner channel (9) for passing liquid. The connection between the adapter (8) and handle (1), handle (1) and head (3), and head (3) and cartridge holder (5) are made detachable by means of a pin/plug connection.

(6) The distal end of the handle (1) is provided with a socket (10) for a pin/plug proximal end of the adapter (8). Mounted on the handle (1) can be a mechanism (11) controlling the flow of liquid in channel (2). The design of the mechanism is not disclosed in detail, but it is known from the prior art and, for example, is the same as in the prototype. Or a section of the channel (2) can be made of an elastic tubing and opening/closing the channel will occur by pressing a button located on the outer surface of the handle. Or the flow control will be performed in the following positions of the mechanism: “open”, “closed”, “more-less”. Mechanism (11) may be absent altogether, and the flow control can be performed directly by the tap water faucet. The cartridge holder (5) is provided with an internal perforated partition (12), which prevents clogging of the slot-type channel (4) of the head (3). At least one extending fin (13) of the holder (5) is made elastic, which helps with installing and securing of the cartridge (7). The connection between cartridge (7) and cartridge holder (5) is configured to allow cartridge floating, which increases the convenience of use and the shaving quality of various body parts.

(7) The models of the shaving sticks with floating heads or elastic (flexible) proximal section of the handle are well known from the prior art. The distal section of the adapter (8) may contain a male (or female) thread (14) or a circular collar (15) for connecting to a water source. In the specific embodiment, a circular collar (16) is provided on the outer surface of the pin/plug end (11) of the adapter (8), while inside the socket (10) at the distal end of the handle (1) along the channel (2), a spring-loaded bushing (17) is installed configured to move across the socket and having an inner diameter matching the outer diameter of the collar. When the adapter is not inserted into the handle, the spring causes a displacement of the bushing in the axial direction relative to the longitudinal axis of channel (2). To insert an adapter into the handle, for example, by using a button, the bushing is moved to a position, in which the axis of the bushing (17) matches the axis of the inserted end of the adapter. After collar (16) passes through the bushing (17), and the end of the adapter is firmly pressed against the elastic ring gasket (18) installed within slot (10) in the direction of water flow, the button is released and adapter (8) is fixed in handle (1).

(8) But this is only a single example of a specific embodiment. There are numerous reliable sealed designs of the pin/plug connection of the (pipeline) parts. Obviously, the shaving stick can be used in the usual way, without using an adapter. Attachment (19), which houses head (20) with cleaning members and which contains a channel interconnected with the channel (2) in the handle (1) and with the outer surface of the head, is installed in the handle (1) and allows to perform oral care. This expands the field of application of the device elements. Toothbrushes with liquid supplied to the head are known: RU 2601930, RU 2549315, and RU 2455914.

(9) The device is easy to manufacture, intuitive to assemble, and convenient to use. When shaving, water acts as a lubricant. Cleaning of the blades from removed hair is also provided, which improves the quality and convenience of shaving. Conditions are created for adopting new models of cartridges in already existing handle with the head, which will reduce consumer expenses. An additional oral care attachment will allow using the handle with the adapter from a razor, which will also reduce consumer expenses. It should be noted that the provided description of the specific embodiment of the invention is given for illustration purposes, since various changes and modifications within the scope of the invention defined by the claims will be obvious for those skilled in the art.

(10) The description of the present disclosure has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the disclosure. In particular, features from one embodiment can be used with another embodiment. The embodiments were chosen and described to best explain the principles of the disclosure and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
