Description

Technical Field

[0001] The utility model belongs to the field of oxygen generators, and particularly relates to an oxygen delivery device. Background Art

[0002] An oxygen generator can provide high-concentration oxygen for patients to help improve respiratory function and increase blood oxygen saturation. In a medical environment, oxygen generators are usually used to treat various cardiopulmonary diseases, such as dyspnea caused by chronic obstructive pulmonary disease, pneumonia, heart disease, etc.

[0003] In an oxygen generator, air is mainly screened by a molecular sieve tank, and the screened oxygen is stored in an oxygen tank. Because of the need to maintain airtightness, the connection between the oxygen tank and the molecular sieve tank needs to be connected through a hose and a sealing valve. This connection method makes it not very convenient to replace the oxygen tank. Because most of the existing connections between the sealing valve and the hose are through screwed connectors. Every time the oxygen tank is full and needs to be replaced with an empty tank, the screwed connector needs to be unscrewed. Summary of the Utility Model

[0004] Technical problem to be solved: How to conveniently replace the oxygen tank.

[0005] Technical solution: The utility model provides an oxygen delivery device, which includes a main body component and a separation component: The main body component includes an oxygen generator. A horizontal partition is installed in the inner tank of the oxygen generator to divide its inner tank into upper and lower tanks. An air storage tank and a molecular sieve tank are placed side by side in the upper tank. The molecular sieve tank is fixed to the partition, and rigid tubes are connected to the tops of both of them. The end of the rigid tube on the air storage tank communicates with a rubber head that can be elastically inserted into the other rigid tube; The separation component includes two horizontally arranged and symmetrically front and rear through grooves opened on the partition. A sleeve frame for clamping and sleeving the air storage tank is connected to the partition through the grooves in a clamping and sliding manner; In addition, on the one hand, a driving mechanism for driving the sleeve frame to slide along the groove is arranged in the lower tank; On the other hand, an automatic closing mechanism that can automatically close after no external gas enters is arranged in the rigid tube on the air storage tank.

[0006] Further, the automatic closing mechanism includes a connecting frame installed in the rigid tube. One end of the connecting frame is connected to a spring. One end of the spring is connected to a rubber ball. A connecting ring fixed in the rigid tube is arranged at the end of the rubber ball away from the spring. The inner diameter of the connecting ring is smaller than the diameter of the rubber ball. In the initial state, the rubber ball blocks the inner diameter of the connecting ring.

[0007] Further, the driving mechanism includes two mounting plates symmetrically left and right about the groove and fixedly connected to the bottom end of the partition. A horizontal bidirectional lead screw is connected between the two mounting plates through bearings. A U-shaped sliding frame is threadedly penetrated through the bidirectional lead screw. The top end of the sliding frame passes through the groove and is fixed to the bottom end of the sleeve frame; At the same time, a rotating mechanism for driving the bidirectional lead screw to rotate is also arranged on one of the mounting plates.

[0008] Further, the rotating mechanism includes a servo motor mounted on the mounting plate, and gears that are fixedly sleeved on the output shaft of the servo motor and the outer peripheral side of the bidirectional lead screw and mesh with each other.

[0009] Further, the tail end of the rubber head communicates with a metal pipe, and an external thread is provided on the outer peripheral side of the metal pipe; at the same time, an internal thread is provided inside the nozzle of the rigid pipe on the gas storage tank, so that the rubber head can be screwed and connected to the rigid pipe through the metal pipe.

[0010] Technical effect: In the present utility model, under the action of the driving mechanism, the sleeve can be driven to move along the sliding groove, so that the sleeve can drive the gas storage tank away from the molecular sieve tank, so that the two rigid pipes are separated. At this time, the rubber head is detached from the rigid pipe on the molecular sieve tank. In this state, the self-closing mechanism in the rigid pipe on the gas storage tank closes the rigid pipe, making the gas storage tank airtight. In this way, by moving the gas storage tank away from the molecular sieve tank, it can be disconnected from the molecular sieve tank and automatically sealed at the same time, facilitating the replacement of the gas storage tank.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0019] The oxygen delivery device provided by this specific embodiment, as Figure 1 and Figure 3 shown, includes a main body member and a separation member, where:

[0020] The main body member includes an oxygen generator 1. A horizontal partition 2 is installed in the inner tank of the oxygen generator 1 to divide its inner tank into upper and lower tanks. An air storage tank 3 and a molecular sieve tank 4 are placed side by side in the upper tank. The molecular sieve tank 4 is fixed to the partition 2, and the top ends of both are connected to a rigid tube 5. The end of the rigid tube 5 on the air storage tank 3 is connected to a rubber head 6 that can be elastically inserted into another rigid tube 5. That is to say, the left rigid tube 5 is connected to the right rigid tube 5 through the rubber head 6.

[0021] The separation member includes two horizontally symmetric front and rear through grooves 7 formed in the partition 2. A sleeve 8 for clamping and sleeving the air storage tank 3 is connected to the partition 2 through the grooves 7 in a clamping and sliding manner; in addition, on the one hand, a driving mechanism 9 for driving the sleeve 8 to slide along the groove 7 is provided in the lower tank, as Figure 2 shown. The driving mechanism 9 includes two mounting plates 901 symmetrically arranged about the groove 7 and fixedly connected to the bottom end of the partition 2. A horizontal bidirectional lead screw 902 is connected between the two mounting plates 901 through a bearing. A U-shaped sliding frame 903 is threadedly penetrated through the bidirectional lead screw 902. The top end of the sliding frame 903 passes through the groove 7 and is fixed to the bottom end of the sleeve 8; at the same time, a rotating mechanism 904 for driving the bidirectional lead screw 902 to rotate is also provided on one of the mounting plates 901. The rotating mechanism 904 includes a servo motor 90401 installed on the mounting plate 901. The output shaft of the servo motor 90401 and the outer peripheral side of the bidirectional lead screw 902 are fixedly sleeved with mutually meshing gears 90402; on the other hand, an automatic closing mechanism 10 that can automatically close after no external gas enters is provided in the rigid tube 5 on the air storage tank 3, as Figure 5As shown, the self-closing mechanism 10 includes a connecting frame 1001 installed in the hard tube 5, one end of the connecting frame 1001 is connected to a spring 1002, one end of the spring 1002 is connected to a rubber ball 1003, and the end of the rubber ball 1003 away from the spring 1002 is provided with a connecting ring 1004 fixed in the hard tube 5, the inner diameter of the connecting ring 1004 is smaller than the diameter of the rubber ball 1003, and in the initial state, the rubber ball 1003 blocks the inner diameter of the connecting ring 1004. In this way, when the hard tube 5 on the left is separated from the hard tube 5 on the right, because no gas is rushed into the gas storage tank 3, the rubber ball 1003 is reset to plug the connecting ring 1004 under the action of the spring 1002, so that the hard tube 5 is sealed, and when oxygen rushes in, the oxygen impacts the rubber ball 1003, so that the connecting ring 1004 is opened, and these two situations correspond exactly to whether the rubber head 6 is plugged into the other hard tube 5.

[0022] In addition, in order to facilitate the replacement and connection of the rubber head 6, as Figure 4 As shown, the tail end of the rubber head 6 is connected to a metal tube, and an external thread 11 is provided on the outer peripheral side of the metal tube; at the same time, an internal thread 12 is provided inside the pipe mouth of the hard tube 5 on the gas storage tank 3, so that the rubber head 6 can be screwed and connected with the hard tube 5 through the metal tube.
