Description

Technical Field

[0001] This utility model belongs to the field of oxygen valve technology, specifically, it relates to an oxygen valve diaphragm and an oxygen valve. Background Technology

[0002] Currently, rubber diaphragms on the market are mainly made of rubber or a rubber-steel composite. Patent CN2632401Y provides a pressure regulating valve diaphragm, including a rubber substrate, with a composite membrane underneath that is resistant to deformation, pressure, and corrosion. The composite membrane can be made of materials such as aluminum foil or polyester. This rubber composite diaphragm combines the corrosion resistance and elasticity of rubber diaphragms with improved resistance to deformation and pressure. Its pressure-bearing strength, swelling resistance, and corrosion resistance are significantly superior to currently used single-layer rubber pressure regulating diaphragms.

[0003] However, the diaphragm cannot rebound quickly, and when the internal space of a rubber-steel composite diaphragm is limited, the thickness of the steel must be reduced. Thinner steel is more susceptible to deformation due to external forces or stress. This prevents the rubber from effectively transferring the rebound force to the steel, leading to valve opening and closing failures. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of this utility model is to provide an oxygen valve diaphragm and an oxygen valve.

[0005] An oxygen valve diaphragm according to the present invention includes: a sealing part, a deformable part, and a fixing part; The deformable part is disposed between the sealing part and the fixing part; The oxygen valve diaphragm of the sealing part is a plastic sheet, which is used to block or loosen the outlet of the oxygen valve. The oxygen valve diaphragm of the deformable part is an elastic component, and the deformable part is used to connect the sealing part and the fixing part; The fixing part is used for the installation of the oxygen valve diaphragm, and the oxygen valve diaphragm is installed at the outlet of the oxygen valve. The elastic component is provided with a corrugated structure, which can rebound after deformation, and is used to apply pressure to the oxygen valve diaphragm in the direction of the outlet after deformation.

[0006] Preferably, the fixing part includes a sealing structure for sealing the oxygen valve by compression.

[0007] Preferably, the fixing part includes a positioning hole for positioning the oxygen valve diaphragm in the oxygen valve.

[0008] Preferably, the elastic component is silicone.

[0009] Preferably, the plastic sheet is a polycarbonate plastic sheet.

[0010] This utility model also provides an oxygen valve, employing the oxygen valve diaphragm described in any one of the above-mentioned embodiments, comprising: The oxygen valve body includes: a pressure-applying component, an air outlet, and an oxygen valve outlet; The end face of the plastic sheet of the oxygen valve diaphragm facing the outlet is a sealing end face, and the other side is a pressure-applying end face; the pressure-applying component is disposed on the pressure-applying end face of the plastic sheet; When air is drawn into the outlet of the oxygen valve, the force on the sealing end face is greater than the force on the pressure end face, the plastic sheet leaves the outlet hole, the corrugated structure on the elastic component deforms, and the oxygen valve opens. When the oxygen valve stops drawing air from its outlet, the deformed corrugated structure rebounds, applying pressure to the oxygen valve diaphragm in the direction of the outlet. The pressure-applying component also applies pressure to the sealing end face. The force on the sealing end face is less than the force on the pressure-applying end face. The pressure-applying component presses the plastic sheet tightly against the outlet, and the oxygen valve closes.

[0011] Preferably, the pressure-applying element is a spring.

[0012] Preferably, the pressure-applying component further includes an adjustable device disposed behind the spring, the adjustable device being used to adjust the force applied by the spring to the pressure-applying end face.

[0013] Compared with the prior art, the present invention has the following beneficial effects: An oxygen valve diaphragm is constructed using a composite of a plastic sheet and an elastic component. The elastic component features a corrugated structure, which, upon deformation, applies pressure towards the outlet to the diaphragm, counteracting the pressure at the outlet. This allows the plastic sheet to effectively seal the outlet, ensuring the oxygen valve remains closed. Furthermore, the plastic sheet is resistant to deformation, preventing the seal from detaching from the outlet and ensuring smooth opening of the oxygen valve. Attached Figure Description

[0015] The diagram shows: Detailed Implementation

[0016] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0017] like Figures 1-3 As shown, this embodiment provides an oxygen valve diaphragm, including: a sealing part 11, a deformable part 12, and a fixing part 13; The deformable part 12 is disposed between the sealing part 11 and the fixing part 13; The oxygen valve diaphragm of the sealing part 11 is made of plastic sheet, which is used to block or loosen the outlet 2 of the oxygen valve; The oxygen valve diaphragm of the deformable part 12 is an elastic component, and the deformable part is used to connect the sealing part and the fixing part. The fixing part 13 is used for the installation of the oxygen valve diaphragm 1, which is installed at the outlet port 2 of the oxygen valve. The elastic component of the deformable part 12 is provided with a corrugated structure 121, which can rebound after deformation and is used to apply pressure to the oxygen valve diaphragm 1 in the direction of the outlet 2 after deformation.

[0018] The fixing part 13 includes a sealing structure 131, which is used to seal the oxygen valve by compression.

[0019] The fixing part 13 includes a positioning hole 132, which is used to position the oxygen valve diaphragm 1 in the oxygen valve.

[0020] The elastic component of the deformable part 12 is made of silicone.

[0021] The plastic sheet of the sealing part 11 is a polycarbonate plastic sheet.

[0022] This embodiment also provides an oxygen valve, including: Oxygen valve diaphragm 1, which is any one of the oxygen valve diaphragms mentioned above; The oxygen valve body includes: a pressure-applying component 3, an air outlet 2, and an oxygen valve outlet 4; The end face of the plastic sheet of the oxygen valve diaphragm 1 facing the outlet 2 is the sealing end face 111, and the other side is the pressure end face 112; the pressure-applying component 3 is disposed on the pressure end face 112 of the plastic sheet. When oxygen is drawn into the outlet 4 of the oxygen valve, the force on the sealing end face 111 is greater than the force on the pressure end face 112, the plastic sheet of the deformable part 12 leaves the outlet hole 2, the corrugated structure 121 on the elastic component deforms, and the oxygen valve opens. When the oxygen valve outlet 4 stops drawing air, the deformed corrugated structure 121 rebounds, applying pressure to the oxygen valve diaphragm 1 in the direction of the outlet 2, and the pressure-applying component 3 applies pressure to the sealing end face. The force on the sealing end face 111 is less than the force on the pressure-applying end face 112. The pressure-applying component 3 presses the plastic sheet tightly against the outlet 2, and the oxygen valve closes.

[0023] The pressure-applying component 3 is a spring 31.

[0024] An adjustable device 32 is provided at the rear of the spring 31. The adjustable device 32 is used to adjust the force applied by the spring 31 to the pressure end face 112.

[0025] In one embodiment, the oxygen valve diaphragm 1 is a circular thin sheet; the oxygen valve diaphragm 1 is installed in the oxygen body through the positioning hole 132.

[0026] The function of the sealing structure 131 is to seal the oxygen valve by compression, thereby controlling the internal pressure difference.

[0027] A spring 31 is applied to the end face of the pressure end face 112. There is an adjustable device 32 behind the spring 31 to adjust the force applied by the spring 31 to the pressure end face 112.

[0028] When the pressure end face 112 is under stress, it applies downward pressure to the sealing end face 111, causing the sealing end face 111 to block the air outlet 2, thus closing the oxygen valve.

[0029] When the user is inhaling, gas is drawn out from the oxygen valve outlet 4. At this time, the negative pressure of the internal ring decreases, and the force on the sealing end face 111 is greater than the force on the pressure end face 112. That is, the pressure at the outlet 2 is greater than the sealing force applied by the sealing end face 111. At this time, the sealing end face 111 is pushed upward, and oxygen comes out from the outlet 2.

[0030] At this time, the corrugated structure 121 on the elastic component deforms. Specifically, the corrugated structure 121 is a silicone corrugated groove. Because the elasticity of the silicone will cause the corrugated structure 121 to drive the plastic sheet of the sealing part 11 to recover downward. At this time, the sealing end face 111 and the pressure end face 112 of the plastic sheet of the sealing part 11 both rebound downward.

[0031] When the user stops inhaling, the rebound force caused by the deformation of the corrugated structure 121 will cause the sealing end face 111 and the pressure end face 112 of the plastic sheet of the oxygen outlet sealing part 11 to return to the initial position. At this time, the force on the sealing end face 111 is less than the force on the pressure end face 112, that is, the sealing force of the plastic sheet is greater than the force of the air outlet 2, and the air outlet 2 is closed.

[0032] By using plastic sheets to seal the air outlet 2, the problem of unevenness caused by easy deformation of the original steel material can be solved.

[0033] Even slight deformation of the steel material can cause the sealing end face 111 of the plastic sheet to detach from the vent hole 2, resulting in valve failure to open.

[0034] By employing a silicone corrugated structure with silicone corrugated grooves, a downward rebound force is applied to the plastic sheet when it is lifted, so that together with the downward pressure applied by the spring, it can counteract the pressure at the vent, allowing the sealing end face to effectively seal the vent.

[0035] By employing a silicone sealing structure, it can be ensured that the pressure difference inside the valve will not be affected by external air pressure.
