Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygen generation equipment technology, and more specifically, it relates to a protective oxygen generation device. Background Technology
[0002] Electronic oxygen concentrators are commonly found in pharmacies. They use a process where oxygen from the air is oxidized and reduced in a solution to produce oxygen, thus avoiding the dangerous hydrogen gas produced by water electrolysis. The machines operate relatively quietly, but these products require very strict handling and usage. They must never be tilted or inverted, otherwise the solution will flow into the oxygen delivery tube and be sprayed into the nasal cavity, causing serious injury to the user.
[0003] Currently available oxygen generators only have anti-collision and vibration damping devices such as rubber strips and springs on the equipment shell, which can alleviate the impact of external forces on the oxygen generator, but cannot deal with the problem of solution leakage. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a protective oxygen generating device that can prevent the solution from being inhaled.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A protective oxygen generator includes a housing with an inlet valve installed on it. The outlet of the inlet valve is connected to a solution tank, which is spherical. A support is fixed inside the housing, and several struts are fixed on the support. The struts are evenly distributed along the tank and together clamp the tank. The tank can rotate between the struts. A counterweight is provided at the bottom of the tank. A cooling tank is connected to the exhaust port at the top of the tank, and an exhaust valve and a pressure reducing valve are connected to the outlet of the cooling tank.
[0007] The present invention is further configured such that the counterweight is disposed inside the tank.
[0008] The present invention is further configured such that: a plurality of steel balls are rolled on the end face of the support rod facing the tank body, and the steel balls abut against the tank body.
[0009] The present invention is further configured such that: a baffle ring is provided around the outside of the exhaust port, one end of the baffle ring is fixed to the inner wall of the tank, the ring wall of the baffle ring is inclined, the other end of the baffle ring extends toward the center of the tank, a baffle net is installed on the opening of the baffle ring away from the exhaust port, and dehumidifying cotton is filled between the baffle net and the exhaust port.
[0010] The present invention is further configured such that: an air inlet is provided on the tank body, the air inlet is located on the side of the tank body near the air inlet valve, one end of the air inlet on the outside of the tank body is connected to the air inlet valve, and one end of the air inlet on the inside of the tank body is connected to a dispersion plate, the dispersion plate being located inside the solution in the tank body.
[0011] The present invention is further configured such that: a control assembly is installed inside the housing, and the intake valve, cooling tank, exhaust valve and pressure reducing valve are all electrically connected to the control assembly.
[0012] The advantages of this utility model are:
[0013] 1. The solution tank is spherical, with a counterweight fixed at the bottom and the vent at the top. The tank is held in place by several struts, with several steel balls between the struts and the tank. The tank can rotate freely between the struts. When the equipment is tilted or inverted, the tank can always remain upright due to the counterweight, thus preventing the solution from entering the vent.
[0014] 2. A retaining ring is installed at the exhaust port. The ring wall is set at an angle. The large diameter end of the retaining ring is connected to the inner wall of the tank, and the small diameter end of the retaining ring faces the solution. When the equipment is impacted and the solution vibrates, the solution will splash upward along the tank wall and be blocked by the retaining ring. Finally, it drips back to the bottom along the retaining ring, thus preventing the solution from leaking out. Attached Figure Description

[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art described in this application.
[0023] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.
[0024] Please see Figure 1-5 The present invention provides the following technical solution:
[0025] A protective oxygen generator includes a housing 1, an inlet valve 2 installed on the housing 1, an outlet of the inlet valve 2 connected to a solution tank 3, an exhaust port 36 at the top of the tank 33 connected to a cooling tank 4, an exhaust valve 5 and a pressure reducing valve 6 connected to the outlet of the cooling tank 4, and a control assembly 7 installed inside the housing 1. The inlet valve 2, cooling tank 4, exhaust valve 5 and pressure reducing valve 6 are all electrically connected to the control assembly 7, forming the main body of the oxygen generator.
[0026] The solution tank 3 has a spherical body 33. A support 31 is fixed inside the outer shell 1. Several support rods 32 are fixed on the support 31. The support rods 32 are evenly distributed along the tank body 33. The support rods 32 together clamp the tank body 33. The tank body 33 can rotate between the support rods 32. A counterweight 34 is provided at the bottom of the tank body 33. The counterweight 34 is located inside the tank body 33 and does not interfere with the support rods 32.
[0027] Several steel balls 321 are rolled on the end face of the support rod 32 facing the tank 33. The steel balls 321 abut against the tank 33, and the tank 33 can easily rotate between the support rods 32. When the equipment tilts or is inverted, the counterweight 34 is always located at the bottom of the tank 33 under the action of gravity, so that the tank 33 maintains an upright state. The solution in the tank 33 will not cover the exhaust port 36 at the top, thereby preventing the solution from escaping.
[0028] A retaining ring 37 is provided around the outside of the vent 36. The ring wall of the retaining ring 37 is inclined. The large-diameter end of the retaining ring 37 is fixed to the inner wall of the tank 33, and the small-diameter end of the retaining ring 37 faces the solution side. The retaining ring 37 is coaxial with the vent 36. When the equipment is impacted, the solution in the tank 33 will oscillate and surge upward along the inner wall of the tank 33. The solution will hit the retaining ring 37 and then drip back to the bottom of the tank 33 along the outer wall of the retaining ring 37, without entering the vent 36, thus preventing the solution from leaking out.
[0029] A baffle 38 is installed at the small diameter end of the baffle ring 37. A dehumidifying cotton 39 is filled between the baffle 38 and the exhaust port 36. The reduced gas passes through the dehumidifying cotton 39 before being discharged. This process can absorb a small amount of moisture in the gas and prevent the solution from escaping with the moisture.
[0030] An air inlet 35 is provided on the tank body 33. The air inlet 35 is located on the side of the tank body 33 near the air inlet valve 2. One end of the air inlet 35 on the outside of the tank body 33 is connected to the air inlet valve 2. The other end of the air inlet 35 on the inside of the tank body 33 is connected to a dispersion plate 8. The dispersion plate 8 is placed in the solution in the tank body 33 and can disperse the incoming gas, promote the contact between the gas and the solution, and improve the reduction effect.
[0031] Specifically, the tank body 33 of the solution tank 3 is spherical, and a counterweight 34 is fixed at the bottom of the tank body 33. The exhaust port 36 is located at the top. The tank body 33 is clamped and fixed by several support rods 32. Several steel balls 321 are arranged between the support rods 32 and the tank body 33. The tank body 33 can rotate freely between the support rods 32. When the equipment is tilted or inverted, the tank body 33 can always maintain an upright state due to the effect of the counterweight 34, thereby preventing the solution from entering the exhaust port 36.
[0032] A retaining ring 37 is provided at the exhaust port 36. The ring wall of the retaining ring 37 is set in an inclined direction. The large diameter end of the retaining ring 37 is connected to the inner wall of the tank 33, and the small diameter end of the retaining ring 37 faces the solution. When the equipment is impacted and the solution vibrates, the solution will splash upward along the tank wall and be blocked by the retaining ring 37. Finally, it drips back to the bottom along the retaining ring 37, thus preventing the solution from leaking out.
