DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0029] Example:

[0030] Reference Figure 1-Figure 4 The embodiment of the utility model provides a low-noise wall oxygen delivery device for hospital use, comprising a bottle body 1, an end cap 2 is detachably installed on the upper port of the bottle body 1, a flow meter 3 for monitoring the oxygen flow, an air inlet pipe 4 for connecting to an oxygen concentrator, an air outlet pipe 5 for discharging oxygen, and a regulating valve 6 for regulating the oxygen flow are installed on the end cap 2, and also includes: a vertical pipe 7 for delivering oxygen into the bottle body 1, which is fixedly installed at the output end of the air inlet pipe 4; wherein, the lower end of the vertical pipe 7 is fixedly connected to a hollow disc 8 connected thereto, and the lower end of the hollow disc 8 is fixedly connected to a plurality of circumferentially distributed branch pipes 9, the number of the branch pipes 9 is 4-10, and the preferred number of the present application is 6.

[0031] Specifically, when in use, the oxygen discharged from the air inlet pipe 4 will be delivered to the vertical pipe 7, the vertical pipe 7 will deliver the oxygen to the hollow disc 8, the hollow disc 8 will divide the oxygen equally into multiple branch pipes 9, and the multiple branch pipes 9 will deliver the equally divided oxygen into the liquid; because the oxygen is equally divided into multiple groups, the multiple branch pipes 9 will discharge small bubbles in various directions of the liquid respectively. Small bubbles of the same volume will produce more surface area, so that the energy generated during vibration is more dispersed, resulting in relatively small noise; thus, the noise of the bottle body 1 can be effectively reduced. At the same time, the oxygen can be fully contacted with the liquid to ensure the humidity of the oxygen.

[0032] In order to cushion the vibration of the bubbles, the above-mentioned multiple branch pipes 9 are all connected with a buffer plate 11 through a sliding component; at the same time, in order to further ensure the buffer performance and safety of the buffer plate, the material of the buffer plate 11 is transparent medical silicone. In order to make the buffer plate always suspended on the surface of the liquid, the sliding component adopted in the embodiment of the utility model includes a sleeve 10 longitudinally slidably connected to the outer wall of the branch pipe 9, and the outer ring shape of the axial end face of the branch pipe 9 is hexagonal; a connecting plate 13 is fixedly connected to the sleeve 10. The buffer plate 11 is fixedly connected to the top of the connecting plate 13, and the top of the connecting plate 13 is fixedly connected with a floating plate 12 that can float on the surface of the liquid. The buffer plate 11 is parallel to the bottom of the bottle body 1, and the buffer plate 11 is provided with evenly distributed buffer holes 17.

[0033] Specifically, during use, the buoyancy of the floating plate 12 will block the buffer plate 11 on the surface of the liquid. When the water level in the bottle body 1 drops, the floating plate 12 will also drop synchronously with the buffer plate 11; after the branch pipe 9 discharges the tiny bubbles, the tiny bubbles will float to the surface of the liquid and eventually burst on the surface of the liquid. At this time, the water mist and vibration generated by the burst will be blocked by the buffer plate 11 with the buffer hole 17, and the buffer plate 11 can reduce the noise generated when the bubbles burst, thereby making the bottle body 1 quieter.

[0034] In order to make the chess and cards float toward the connecting plate, a curved tube 14 is fixedly connected to the lower end of the branch tube 9, and the output end of the curved tube 14 faces the upper port of the bottle body 1; wherein the connecting plate 13 is inclined to the buffer plate 11, and the output end of the curved tube 14 faces the lower end inclined surface of the connecting plate 13.

[0035] Specifically, when the branch pipe 9 discharges oxygen, the curved pipe 14 discharges the bubbles generated by the oxygen toward the inclined connecting plate 13. When the bubbles float upward, they roll or slide along the inclined surface of the inclined connecting plate 13, so that the bubbles can be in more sufficient contact with the liquid to ensure the humidity of the oxygen.

[0036] In another embodiment, the inclination angles of all the connecting plates 13 are different, so that the bubbles discharged from each curved tube 14 will not float to the liquid surface at the same time, thus preventing all the bubbles from bursting at the same time and generating loud noise.

[0037] The researchers analyzed that in order to enable the connecting plate to also buffer the noise generated by the bubbles, a plurality of evenly distributed fine holes 16 are provided on the outer wall of the connecting plate 13. When the bubbles slide along the surface of the connecting plate 13, the fine holes 16 can cause the bubbles to encounter resistance and cause some of the bubbles to split into multiple small bubbles again, which can further reduce the noise generated by the bubbles.

[0038] In order to reduce the noise generated by the bottle body, a cover shell 15 is fixedly provided on the outer wall of the bottle body 1, and a sound insulation gap is provided between the inner wall of the cover shell 15 and the outer wall of the bottle body 1. The material of the cover shell 15 is the same as that of the bottle body 1. When imaging is generated in the bottle body 1, the cover shell 15 and the sound insulation gap can achieve a sound insulation effect, thereby reducing the impact of noise on the surrounding environment.

[0039] The diameter of the circle formed by the above-mentioned multiple buffer plates 11 is half the diameter of the bottle body 1, that is, the buffer plates 11 are at the same distance from the inner wall of the bottle body 1 and the axis of the bottle body 1, so the buffer plates 11 can buffer and reduce noise of bubbles and liquid more efficiently.

[0040] like Figure 5 As shown, the connection plate 13 is in the shape of a tile, and the concave surface of the connection plate 13 is arranged downward. When the bubble floats to the inclined surface of the connection plate 13, the concave surface can prevent the floating position of the bubble from being offset, and the bubble floats to the buffer plate 11 more accurately.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
