New description: [New technical field] This is a kind of magnetic exhaust valve, which has good adhesion and is not easy to leak. It can set the appropriate threshold pressure to avoid the magnetic exhaust valve being too sensitive, and can be applied to Personal protective equipment and shoes (bottom) exhaust. [Prior Art] _ Referring to the first figure, the exhaust valve structure of the conventional respiratory protection device (for example, a mask) includes at least: a respiratory protection device 81, an exhaust gas body 82 disposed on the respiratory protection device 81, and a circular cushion 83, the exhaust valve body 82 is provided with a rib 821, a blocking portion 822, a plurality of ventilation openings 823 and a fixing convex portion 824; the center of the circular cushion 83 is fixed at the center The convex portion 824 is fixed, and the outer edge of the circular cushion 83 contacts the supporting portion 822. ^ When the user inhales, as shown in the second figure, the air pressure in the respiratory protection device 81 is lower than the external air pressure, since the circular cushion 83 is removed from the rib 821 and the stop portion from 2 _ As a result, the gas cannot flow into the vent opening 823, and it is in a "closed" state. At this time, most of the outside air penetrates through the respiratory protection device 81 (as indicated by arrow F1), but there is still a small amount. The gas flows in through the gap between the cushion 83 and the stopper 822 (as indicated by the arrow F2), causing a problem of a slight leak, which is in the ward (having high infectivity and high silk) or full of poisonous nucleus In Wei, it is possible to inhale 14 high-grade pathogenic bacteria, high-sensitivity virus or poisonous nucleus. When the user exhales, as shown in the third figure, the air pressure in the respiratory protection device 81 is higher than the external air pressure, and the circular cushion 83 is blown away from the stopper 822 (at least 5 M329356 is partially left) Therefore, most of the gas leaves through the vent opening 823 (as indicated by arrow F3), and is in an "open" state, and part of the exhaust gas is discharged to the outside through the respiratory protection device 81 (such as the arrow " However, if the user exhales a little, the traditional breathing apparatus exhaust valve may open, the reaction is too sensitive, it is easy to cause high infectious bacteria, high... Infectious virus or toxic gas countercurrent Into the user's mouth. • In addition, since the circular cushion 83 must be a soft material, the contact with the stopper 822 cannot be closely contacted, and gas leakage or adhesion is not completely serious. The problem 'especially in the ward (high infectious disease g and highly infectious virus) or in an environment full of toxic gases, it is more harmful to the human body. Therefore, it is necessary to develop a new technology to solve the traditional structure. [New content] The main purpose of this creation is to provide a magnetic row _, which has good adhesion and is not easy to leak. 丨, the second purpose of this creation is to provide a magnetic exhaust valve that can set the appropriate door. The pressure to avoid the magnetic exhaust valve is too sensitive. The purpose of this creation is to provide a magnetic row _, which can be applied to personal protective equipment and shoes (bottom) exhaust. This creation provides a magnetic exhaust The valve comprises: a valve seat, which is separated by a solid object - an internal space and an external space, the valve seat has at least one first, a fixed port, a contact portion and a ventilation 6 M329356 ★ - The diaphragm that deforms and returns to the original shape has a second fixing portion and a second contact portion, and the at least one of the i-closed position and the -opening position; wherein the first contact portion and the second contact portion Between the occurrence of a predetermined magnetic attraction 'by this', the value of the (10) miscellaneous clock minus the material of the clock is defined as the air pressure difference, when the air pressure difference is greater than the predetermined door strength, the diaphragm is The closed position is moved to the starting position, By arming position to the closed position. "The above object of the present invasive money classification points, still from the detailed description of the embodiments thereof, New York, _ with the accompanying drawings, the gain insight. The following embodiments are described in detail with reference to the drawings: [Embodiment] Referring to the fourth, fifth and sixth figures, the present invention is a magnetic exhaust enthalpy comprising: a valve seat 10, The utility model is configured to be fixed on the object 90 to separate an inner space 10A and an outer space side. The valve seat ω has at least a first fixing portion, a first contact portion 12 and a venting portion 13; Recovering the original diaphragm 20, the diaphragm 2 has at least a second fixing portion 21 and a second contact portion 22, and the diaphragm 2 is deformable at least between a closed position P1 and an open position P2. Wherein, a predetermined magnetic attraction force F is generated between the first contact portion 12 and the second contact portion 22 (as shown in FIG. 6), whereby the air pressure of the internal space 1A is subtracted from the external space. The value of the air pressure of 10B is defined as the air pressure difference Δρ. When the air pressure difference Δρ is greater than a predetermined threshold pressure, the diaphragm 20 is moved from the closed position P1 to the open M329356 open position P2, and vice versa. Move to the closed position P2. This is the magnetic exhaust valve of this creation. Referring to the fifth figure, assuming that the object 90 is implemented in a personal protective device (such as a mask), the object 90 is covered in a breathing area (such as the mouth and the nose), and the internal space is located between the personal protective device and the breathing portion. The external space 1〇B is the external environment. When the first contact portion 12 and the second contact portion 22 are attracted to each other due to the magnetic attraction force F, the film 20 is sealed on the fixing portion 10 at the position of the closing portion | position P1 〇 At the time of inhalation, since the gas flows from the external space 10B to the internal space 1A, the first and second contact portions 12 and 22 are mutually attracted by the magnetic attraction force F, and then subjected to strong air pressure suppression ( The more the suction is applied, the greater the generated air pressure, so that the diaphragm 2 is tightly closed to the closed position P1 of the fixed portion 10 (may also return from the open position P2 to the closed position P1) It is effective to prevent any dangerous gas from passing through the four spaces 10B through the first and second contact portions 12 and 22 while inhaling, and ► infiltrating into the internal space 10A. When the gas pressure is discharged, the air pressure difference ΔΡ of the air pressure of the inner space 10A minus the air pressure of the outer space 10B is greater than a predetermined threshold pressure; then the diaphragm 2 is closed from the closed position P1 (the second contact portion 22 contacts the first A contact portion 2) is moved to the open position P2G, and the first contact portion 22 is separated from the first contact portion 12), and the discharged gas flows from the internal space 10A through the vent portion 13 to the external space ιο. Of course, if the air pressure difference ΔΡ generated by slight exhalation is less than the predetermined threshold pressure, the diaphragm 20 is still in the closed position pi and does not operate, so as to avoid the magnetic exhaust valve 8 M329356 being too sensitive to the third figure. The thickness of the diaphragm 20 can be gradually decreased from the second fixing (four) to the first contact portion 22. ^第帛-Contacts 12 and 22 have the following cooperative embodiments: i The first contact portion 12 is a magnet (for example, the magnetic strength is in the range of ι 〇〇 Gauss to two _ ' the second contact portion 22 is The magnet attracts the material. The λ-contact portion 22 is a magnet (10) such as a magnetic strength between a Gaussian and a 500-scores--the 4th-contact portion 12 is a material that can be attracted by a magnet. * Ρ] The second contact portions 12 and 22 are magnets and are attracted to each other (as shown in the eighth figure). The shape of the diaphragm 2 is selected from the group consisting of a circular shape (as shown in the fourth figure), a fan shape (as shown in the ninth figure), and a rectangular shape (as shown in the tenth figure). As shown in Fig. 11, the object 90 can be implemented on a shoe (e.g., a sole) in addition to being implemented in a personal protective device. The advantages and effects of this creation are as follows: [1] Good adhesion is not easy to leak. Since the first contact portion and the second contact portion of the present invention have a predetermined magnetic attraction force, the degree of adhesion is better, and air leakage is less likely to occur, thereby improving the safety in use. [2] The appropriate threshold pressure can be set to avoid the magnetic exhaust valve being too sensitive. With the appropriate magnetic attraction force, the magnetic exhaust valve is opened when the air pressure difference is greater than a predetermined threshold pressure, thus avoiding the problem that the magnetic exhaust valve is too sensitive. [3] Applicable to personal protective equipment and shoes (bottom) exhaust. This creation can be applied not only to the 9 M329356 personal protective gear, but also to the exhaust valve of the shoe (bottom). When the magnetic exhaust valve is closed, it can prevent the splash of water from __, so at least Personal protective gear and exhaust structure of the sole. The above is only a summary of the details of the invention, and any fresh modifications and variations to the embodiments are intended to be departing from the spirit and scope of the present invention. From the above detailed description, it can be made clear to the skilled person that the creation can achieve the above-mentioned purpose, and has already met the requirements of the Patent Law, and proposes a new patent application.
