Description

Breathing device capable of continuously generating negative ions

Technical Field

The invention relates to a breathing device capable of continuously generating negative ions, in particular to a breathing device which not only has a filtering function, but also can continuously generate air negative ions, and belongs to the technical field of medical health and daily protective articles.

Background

The air anion is beneficial to improving respiratory function, optimizing skin state, enhancing cardiovascular function, reducing blood pressure, and recovering the health of patients with cardiovascular and cerebrovascular diseases; can improve the self life vitality of human body and improve the endocrine function; can also improve allergic constitution, enhance immunity, regulate autonomic nerve, resist free radical oxidation, eliminate active oxygen, activate cells, promote cell function, and enhance body resistance; however, the service life of the negative ions is usually about several seconds to tens of seconds, if the negative ion generating end is far away from the respiratory tract opening, the negative ions are difficult to enter the respiratory tract, and the negative ions are very easy to combine with the particles suspended in the air, so that a large amount of fine particles are loosely aggregated into larger ' pollution particle groups ', and the pollution particle groups ' unconsciously enter the human body along with the breathing, and the loosely combined ' pollution particle groups ' are rapidly separated into a plurality of finer particles in the respiratory tract, are difficult to be removed by a mucous cilia removing system of the respiratory tract, and cause more serious damage to the human body.

To address the pathogenic particulate matter in the air, wearing various respiratory protective masks has been a routine choice for humans; in addition to the filtering effect of the filtering unit, the better breathing protective mask in the prior art is also provided with the anion unit, so that the anion can be inhaled in a short distance while the cleaner air is inhaled; chinese patent publication No. CN212065769U discloses an N95 type anion mask, but the mask is not provided with a reliable sealing unit, and particulate matter easily enters from the side of the mask and combines with anions to enter into a breathing passage, causing harm to human body, and the amount of anions generated by the anion coating adopted in the mask is small, and the service life is short; chinese patent publication No. CN211861897U discloses a mask with an anion unit, in which although an arc-shaped frame attached to a human face is provided on the outer periphery of the mask body, the anion generator is not connected to a structure for supplying and/or recovering electrons, and thus air anions cannot be continuously generated.

In order to guarantee the breathing safety and fully exert the breathing gain function of the negative ions, a specially designed breathing device capable of continuously generating the clean negative ions is urgently needed to be developed.

Disclosure of Invention

The invention aims to provide a breathing device capable of continuously generating negative ions, which comprises a filtering unit, a sealing unit and a negative ion unit, wherein at least the periphery of the sealing unit is in conformal fit with skin at the corresponding position of a face; the air outside the outer respiratory cavity is filtered by the filtering unit, flows through the negative ion generating end to generate air negative ions to be sucked into the respiratory tract of a human body, and also comprises an electron supply part and/or a negative ion generating end anti-condensation part; the electron supply component is directly or indirectly connected with the negative ion unit; the filter unit, the sealing unit and the like described in the present invention may be constructed of one or more members.

The filtering unit is in a single blade shape and is connected with the sealing unit in a sealing way, or the front blade and the rear blade in the blade shape can be connected into an assembly in a sealing way and then are connected with the sealing unit in a sealing way.

Free electrons released by the negative ion generating end of the negative ion unit are mainly captured by oxygen molecules to form negative ions, the breathing device is usually difficult to obtain continuous electron supply through connecting the ground when in use, if sufficient electron supply is not available, the quantity of the free electrons released by the negative ion generating end of the breathing device is rapidly and greatly reduced and even returns to zero, and the requirement that the breathing device continuously provides the negative ions for the respiratory tract of a human body cannot be met.

In order to ensure more stable, continuous and high-concentration supply of negative ions, an implementation mode of an electron supply component is provided, wherein the electron supply component is at least positioned in a part of a breathing outer cavity and is adjacent to a negative ion generating end, the electron supply component is in a specific shape including a fence shape, a brush shape, a sheet shape, a honeycomb shape, a net shape and a strip shape, and the electron supply component is connected with a power line and/or a functional ground line of a negative ion unit; the electron supply part is made of materials rich in free electrons and/or easy to flow on the free electrons, such as various metals, conductive rubber, conductive ceramics, piezoelectric materials and the like.

In another implementation of the electron supply component, the electron supply component is distributed on the component forming the external breathing cavity and can cover all or part of the area of the component; the electronic supply component can also directly participate in the formation of the external respiratory cavity, namely the electronic supply component simultaneously becomes a component for forming the external respiratory cavity; electrons on negative ions which are not inhaled into a human body in the breathing outer cavity can be recovered to the negative ion unit through the electron supply part.

In another implementation manner of the electronic supply component, the electronic supply component is a frenum which can transmit electrons and is in contact with the head, neck and skin of a user, the frenum which can transmit electrons is directly or indirectly connected with a power line and/or a functional ground wire of the anion unit, free electrons on the surface of a human body continuously enter the anion unit through the frenum, and the huge body surface area of the human body can continuously obtain the free electrons from the surrounding space.

In order to avoid negative ions from flowing back to the negative ion generating end and entering the respiratory tract in an ideal laminar flow mode, the negative ion respirator also comprises a negative ion channel communicated with the respiratory outer cavity, the negative ion channel is provided with a channel air inlet and a channel air outlet, the channel air inlet is connected with a filtering unit, external air enters the negative ion channel through the filtering unit and then enters the respiratory outer cavity through the channel air outlet; at least the negative ion generating end of the negative ion unit is arranged in the air outlet of the channel of the negative ion channel or in the adjacent area, so that the purified air is ensured to capture free electrons released by the negative ion generating end to generate clean air negative ions.

Furthermore, in order to inhale a larger amount of air negative ions, the air outlet of the negative ion channel arranged on the respiratory outer cavity is adjacent to and faces the human respiratory tract opening; the air outlet structure can be specifically arranged according to different people, for example, an opposite mouth part is used by a pharyngitis patient, an opposite nostril is used by a rhinitis patient, and the air outlet structure can also be arranged in an adjustable direction.

Because liquid water can seriously influence the negative ion generating end to release free electrons, in order to prevent water vapor from condensing near the negative ion generating end, the negative ion generating end anti-condensation component is a one-way air valve structure, the one-way air valve is opened when breathing in, and the negative ion generating end is directly communicated with the opening of a respiratory tract; when the user exhales, the one-way air valve is closed to prevent the exhaled water vapor from contacting the negative ion generating end.

Another way to realize the anti-condensation component of the anion generating end is to arrange a heating structure near the anion generating end to prevent the condensation of water vapor.

In order to avoid negative ions entering the filter material and neutralizing positive charges on the filter material to influence the filtering effect and the service life, an air channel is arranged between the filtering unit and the breathing outer cavity, a mesh-shaped, needle-shaped and annular electric conductor is arranged in the air channel, and electrons on the negative ions are absorbed by the electric conductor with larger surface area and cannot enter the filter material.

The part of the sealing unit, which is contacted with the skin, consists of a nose area, an oral area and an oral-nasal transition area which are connected into a whole, and in order to realize dynamic sealing, the sealing unit also comprises at least one elastic unit which can be contacted with the oral area of the sealing unit; one end of the elastic unit is connected with the sealing unit, when a user closes the mouth, the lower jaw joint is closed, the skin of the mouth area of the face is tightly contacted with the mouth area of the sealing unit, and the elastic unit is pressed by the corresponding part of the mouth area of the sealing unit to generate deformation and/or displacement and store energy elastically; when the mouth is opened, the lower jaw joint is opened to drive the skin of the mouth area of the face to move downwards and backwards, the stress on the elastic unit is partially relieved, the elastic potential energy is released, and the elastic unit is reversely deformed and/or displaced so as to drive the mouth area of the sealing unit to synchronously move downwards and backwards, so that the dynamic sealing with the skin of the mouth area of the face is realized, and the generation of clean negative ions is ensured.

The elastic unit action target area is positioned at the mouth area part of the sealing unit contacted with the skin under the lower lip or at the mouth area part of the sealing unit contacted with the skin of the cheeks at two sides; the elastic unit can directly or indirectly act on the target area, and the indirect action means that the elastic unit directly acts on the sealing unit which is not in direct contact with the skin and then transmits the force to the mouth area part of the sealing unit which is in contact with the skin.

In order to improve the transmission of the elastic force and avoid the loss of the elastic force caused by the absorption of the elastic force part by the excessively flexible sealing unit, the elastic unit is connected with the opening area of the sealing unit through a hard connecting seat.

In order to increase the freedom of movement, facilitate adjustment and better realize dynamic sealing, the elastic unit is a joint type elastic unit which can be one-section or multi-section and comprises a ball-and-socket joint, a pulley joint, an oval joint, a saddle joint and the like; the elastic unit and the sealing unit can be connected in a plug-in mode, and installation and adjustment are convenient.

The face mask further comprises a fan unit, the unit is started when the user feels sultry, the fan unit drives external environment air to flow through the negative ion generating end, and condensation of water vapor at the negative ion generating end during expiration is avoided.

For aesthetic purposes, a sheet-like cover shell is included which is fastened to the device during use, and a strap is attachable to the cover shell.
