Respirators are commonly worn by a person over the respiratory tract for at least two of the most typical purposes: 1) to prevent the entry of contaminants or particles into the wearer's respiratory tract; 2) to protect other people or things from exposure to pathogens or other types of contaminants exhaled by the user. In the first case, the respiratory mask is worn in an environment where the air contains particles harmful to the wearer, such as in a body shop. In the second case, the respiratory mask is worn in an environment where there is a risk of transmission of contamination to other persons or things, such as in an operating room or in a clean room.

From the prior art commercially available domestic masks (front parts of gas masks) MGP, MGP-V (TU G-10-1105-82), MB-2 (3688.00.00 TU) with an exhalation unit containing two identical exhalation valves arranged in series one after the other on coaxially threaded cylindrical saddles.

A disadvantage of the design of the known exhalation unit of these masks is the significant distance of the exhalation valves from each other due to the presence and impossibility of implementing communication functions and obtaining additional options necessary to ensure human life.

Known respirator, in which to improve the output of exhaled air from the internal airspace of the respirator to the base of the mask can be attached to the exhalation valve. The use of an exhalation valve also creates more comfortable conditions for the user due to the faster removal of warm and moist exhaled air from the internal space of the respirator (RF patent 2434658, IPC A62B 7/10 (2006.01); publ. 27.11.2011). However, the presence of two independent valves makes the design heavier, moreover, the respirator does not have the function of switching the user with other subjects.

A valve-intercom with an exhalation valve is known, including a membrane element in the form of a rigid disk-shaped body and an exhalation valve made of elastic material, which is a figured part in the form of a body of rotation with an annular niche, a central hole and an elastic element in the form of a shell of rotation. The membrane element is located opposite the central hole and is installed in the annular niche of the rotation body, on the outer surface of which a split plastic clip is installed with an interference fit. EFFECT: improved performance of the device: reduction in weight, reduction in dimensions (RF patent No. 2340374, IPC A62B 18/00 (2006.01), A62B 9/00 (2006.01); publ. 10.12.2008). However, this device does not provide the ability to transmit sound over a considerable distance while providing the user with additional services that improve the quality of use of protective equipment.

The closest to the claimed solution is the invention "Respiratory protection device" / "Respiratory protection device" (US patent No. US9901758, publ. 27.02.2018). The respiratory protection device comprises a face mask configured to cover at least the mouth and nostrils of the wearer and allow inhalation air to enter the inside of the face mask when worn; a voice amplifier including at least a microphone and a speaker; a detection unit configured to detect, directly or indirectly, changes in internal pressure on the inside of the face mask when worn due to inhalation and exhalation of the wearer; power supply unit; and a control unit electrically connected to the voice amplifier and the detection unit. The control unit controls to put the speech amplifier into operation or inoperative state based on the result of comparing the information from the detection unit with the determination reference in the control unit.

The disadvantage of this device is the inability to use it on other protective equipment. In particular, the valve cannot be separated from the respiratory protective device while retaining the useful properties of the device for use on other respiratory protective equipment.

The technical task is to create a multifunctional reusable valve on various protective equipment, which makes it possible to increase communication between users and the devices they use in the course of their activities with increased comfort.

To solve the set technical problem, the valve, placed on the face protection means, contains a body made in the form of a shell, which is a hollow cylinder, on one side of which there is a support platform. A threaded thread is made in the upper part of the side of the body. In the valve support area, inhalation and exhalation membranes are made, while the inhalation membrane is connected to a shell containing a threaded thread on the inner side, while the edge of the outer end of the shell is made pointed. On the support platform of the valve - its front side - there is a communication node, including a microphone, speaker, bluetooth, connected to a power source. The shell connected to the inhalation membrane is connected to a sleeve with an external thread containing a flange covering the pointed part of the shell. In order to be able to screw any functional elements onto the valve, for example, an adapter for communication with other devices, a thread and longitudinal ribs are made on the side wall of the valve to prevent hands from slipping when screwing other devices onto the valve. The pointed part of the edge of the outer end of the shell can be made in the form of teeth that enhance the cutting ability of the edge.

The essence of the claimed technical solution is illustrated by drawings:

The valve includes a housing 1 containing a support pad 2. In the upper part of the side 3 of the housing 1, threaded threads 4 and longitudinal ribs 5 are made. , bluetooth 13, connected to a power source or a means of connecting to a power source (not shown in the figures). The inhalation membrane 6 is connected to the attachment point 10, made in the form of a section of a hollow pipe - a shell, on the inside of which a thread 11 is applied, and the edge 12 is made pointed.

The valve body 1 is made in the form of a segment of a hollow pipe - a shell, from the outside, the outer side is closed by a support platform 2, made in the form of a disk, which serves to fix the working elements of the valve, in particular the inhalation membrane 6 / exhalation 7, microphone 8, speaker 9, bluetooth 13. Communication devices can be combined into a single standard communication node, depending on the use of component parts.

In the upper part of the side side 3 of the valve body 1, a threaded thread 4 is made, which serves to connect various external devices (directly to it or through an adapter - adapter), for example, a filter, an air purifier, an oxygen cylinder, a fan. In addition, on the outer side of the side wall 3 of the housing 1, longitudinal ribs 5 are made, designed to reduce sliding and scrolling of the valve when connecting external devices. In this case, the longitudinal ribs 5 can be made at an angle or replaced by a notch.

The fastening unit is intended for fastening the multifunctional valve on the surface of the product (mask, respirator, scarf, balaclava collar, etc.). The lower sharp edge 12, possibly made with teeth, is designed to cut through the fabric on which the valve is attached using a clamping element, made, for example, in the form of a sleeve containing an external thread for attaching to the shell with screwing on a screw thread 11 or a nut, which allows fasten the cut parts of the fabric to the valve, as is done with the grommet, ensuring that the valve is securely attached. The bushing flange makes it possible to close the sharp edge of the pointed edge 12 and exclude unwanted contacts with surfaces adjacent to the assembly: clothing, the user's body. This sleeve performs a clamping function, securing the valve to the object of attachment. In this case, the threaded thread can be applied to the outer surface of the shell of the mount 10, and the threaded sleeve or nut will contain an internal thread, causing a reliable fixation of the valve on the surface of the protective element (mask, respirator, balaclava, scarf, etc.). As a fixing element, a system of push buttons-fasteners can be used, which are based on the principle of operation of a hidden spring. However, the elastic properties of such a connection weaken over time, and the valve fixation loses its reliability.

The communication node is made multifunctional, allowing to provide reliable communication with the outside world due to the presence of a microphone directed inside the valve and a speaker directed outward, communication devices, such as the WF module, Bluetooth. The standard electronic circuit of a wireless sound transmitting amplifying device for a valve with a bluetooth function, shown in Fig. 5, allows the implementation of the sound transmission function. To implement the valve, a HIPER Protey Mini mini speaker, 5 W, Cyan can be used. The device may contain a charging connector: USB Type-C.

The ability to connect additional external devices to the multifunctional valve enhances its versatility, allowing you to implement additional functions, such as supplying the user with oxygen through an Armed 7F-5L oxygen concentrator connected to the valve, an inhaler, etc.

This device can be implemented in mass production using modern equipment and standard components.
