Description

Technical Field

[0001] The utility model relates to the field of oxygen concentrators, in particular to an oxygen humidification cup structure and an oxygen concentrator comprising the same. Background Art

[0002] The oxygen humidifier cup in the oxygen concentrator is an important accessory in the oxygen concentrator. Its main function is to humidify the oxygen produced by the oxygen concentrator so that the oxygen becomes moist before inhalation and reduces discomfort to the respiratory tract.

[0003] In existing oxygen concentrators, the oxygen humidification cup is separated from the oxygen supply pipe outside the oxygen concentrator. The oxygen humidification cup returns the humidified oxygen to the pipe inside the oxygen concentrator and outputs it from the oxygen outlet on the oxygen concentrator body. The oxygen supply pipe is installed on the oxygen outlet on the oxygen concentrator body. This method will cause the humidity of the oxygen humidified by the oxygen humidification cup to decrease after passing through the pipe inside the oxygen concentrator. For example, water vapor will condense on the inner wall of the pipe inside the oxygen concentrator, resulting in the humidity of the oxygen finally entering the oxygen supply pipe cannot be guaranteed. Utility Model Content

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and to provide an oxygen humidification cup structure and an oxygen concentrator including the same.

[0005] According to one aspect of the present invention, an oxygen humidification cup structure is provided, comprising:

[0006] The cup body has an air inlet and an air outlet on the top;

[0007] An adapter, an air inlet pipe is provided at the bottom of the adapter, a connecting pipe is provided on the side of the adapter that is connected to the air inlet pipe and is used to connect to the oxygen outlet of the oxygen concentrator, an air outlet pipe is provided on the adapter, the bottom of the air outlet pipe extends from the bottom of the adapter, a socket for connecting the oxygen supply pipe is provided on the top of the adapter, the top of the air outlet pipe is located in the socket, the air inlet pipe is plugged into the air inlet, the bottom of the air outlet pipe is plugged into the air outlet, and the adapter is detachably connected to the cup body; and

[0008] The rubber cover can cover the socket or open the socket.

[0009] The oxygen humidification cup structure of the utility model is installed on the oxygen concentrator, the connecting pipe on the adapter is communicated with the oxygen outlet on the oxygen concentrator, and the end of the oxygen supply pipe connected to the nasal plug oxygen inhalation tube or the oxygen inhalation nasal mask is installed on the socket. When the oxygen concentrator is working, the oxygen produced by the oxygen concentrator enters the cup body through the connecting pipe, the air inlet pipe, and the air inlet. After being moistened by water in the cup body, the oxygen is discharged to the nasal plug oxygen inhalation tube or the oxygen inhalation nasal mask through the air outlet, the air outlet pipe, the socket, and the oxygen supply pipe in sequence for the user to breathe. The water content of the oxygen discharged from the oxygen supply pipe is increased, thereby realizing oxygen humidification. When the oxygen supply pipe is removed from the socket, the rubber cover can be closed on the top of the socket to prevent foreign matter from entering. Or dust enters the socket, ensuring hygiene and safety. The oxygen humidification cup structure of the utility model outputs the oxygen humidified by the cup body directly to the oxygen supply pipe outside the oxygen concentrator. The humidified oxygen does not need to be output back to the pipeline inside the oxygen concentrator, which can avoid the condensation of water vapor carried by the humidified oxygen in the pipeline inside the oxygen concentrator, ensuring the humidity of the oxygen entering the oxygen supply pipe. In addition, the oxygen supply pipe outside the oxygen concentrator is detachably connected to the adapter, and the adapter is detachably connected to the cup body. The oxygen humidification cup structure and the oxygen supply pipe outside the oxygen concentrator can be transported and stored as a whole. At the same time, it is also convenient to clean the adapter and the cup body separately to ensure hygiene and safety.

[0010] Furthermore, it also includes a cap and a pressure relief block. The top of the cup body is provided with a convex ring and a pressure relief hole. The pressure relief hole is located at the bottom of the space enclosed by the convex ring. The side wall of the convex ring is provided with a notch. The bottom of the cap body is provided with a convex column. The pressure relief block is provided with a concave cavity. The bottom of the convex column is inserted into the cavity. The cap cover is provided on the top of the convex ring. The bottom of the adapter is provided with an accommodating cavity. The cap body is accommodated in the accommodating cavity.

[0011] When the air pressure in the cup is less than or equal to the set value, the pressure relief block blocks the pressure relief hole.

[0012] When the air pressure in the cup body is greater than the set value, the pressure relief block is separated from the pressure relief hole and the gas in the cup body can be discharged through the notch on the side wall of the convex ring.

[0013] Therefore, since the bottom of the boss is inserted in the cavity, the pressure relief block has an up and down floating space at the bottom of the boss. When the pressure of the oxygen in the cup body is greater than the set value, the oxygen in the cup body will push the pressure relief block upward through the pressure relief hole to separate the pressure relief block from the pressure relief hole. At this time, part of the oxygen will leak out through the notch on the side wall of the convex ring. When the air pressure in the cup body is less than or equal to the set value, the pressure relief block will block the pressure relief hole downward under the action of its gravity, thereby ensuring that the pressure of the oxygen in the cup body remains within a reasonable range. The presence of the boss on the cap body can ensure that the pressure relief block is always located directly above the pressure relief hole to prevent the pressure relief block from being displaced during the up and down floating process. Moreover, the presence of the accommodating cavity can ensure that the cap body is always covered on the top of the convex ring, ensuring that the bottom of the boss on the cap body can always be inserted into the cavity on the pressure relief block, ensuring that the pressure relief block is always located directly above the pressure relief hole.

[0014] Furthermore, a bendable strip is provided on the side of the plastic cover, with the end of the strip positioned on the socket. Therefore, when the oxygen supply tube outside the oxygen concentrator is removed from the socket on the adapter, the strip can be bent to fit the plastic cover over the top of the socket, preventing foreign matter and dust from entering the socket and ensuring sanitation and safety. The end of the strip positioned on the socket prevents the plastic cover from being lost.

[0015] Furthermore, a lifting portion is provided on the side of the rubber cover, so that the rubber cover can be easily removed from the socket by the lifting portion.

[0016] Furthermore, the top of the adapter is equipped with anti-slip protrusions. Therefore, when installing the oxygen humidification cup structure on the oxygen concentrator, the connecting tube connected to the oxygen outlet of the oxygen concentrator is located on the side of the adapter. Therefore, it is necessary to push the adapter horizontally to insert the connecting tube into the oxygen outlet of the oxygen concentrator. The anti-slip protrusions on the adapter can prevent slipping when pushing the adapter horizontally.

[0017] Furthermore, the top of the cup body is open, and a cup lid is provided on the top of the cup body, which is threadedly connected to the cup body. The air inlet, air outlet, convex ring, and pressure relief hole are all provided on the cup lid. Therefore, the detachable connection between the cup lid and the cup body also facilitates cleaning of the interior of the cup body and the cup lid.

[0018] Furthermore, the bottom of the cup body is open and is provided with a heat-conducting cover. The bottom of the cup body is provided with a convex edge extending outward, and the heat-conducting cover is provided with an inner groove facing the center of the heat-conducting cover. The convex edge of the cup body is inserted into the inner groove. Therefore, a heating component can be provided on the oxygen concentrator. After the oxygen humidification cup structure is installed on the oxygen concentrator, the heating component can heat the heat-conducting cover, and the heated heat-conducting cover can heat the water in the cup body. The controller of the oxygen concentrator controls the heating component to maintain the temperature of the water in the cup body within a certain range, ensuring that the humidified oxygen maintains a certain temperature, allowing the user to breathe comfortable oxygen.

[0019] Furthermore, two sloped slots are provided on the inner wall of the socket, and the slots are provided with a card slot for matching with the end of the oxygen supply tube. The external oxygen supply tube of the oxygen concentrator can be installed with an end head, and plug-ins arranged obliquely are respectively provided on both sides of the end head (the shape of the plug-in is adapted to the shape of the slot), and a buckle is formed on the plug-in (the shape of the buckle is adapted to the shape of the slot), and the external oxygen supply tube of the oxygen concentrator can be snapped into the slot on the socket through the buckles on the two plug-ins on the end head, ensuring that the end head of the external oxygen supply tube of the oxygen concentrator can be firmly plugged into the socket and will not be easily dislodged. When the external oxygen supply tube of the oxygen concentrator needs to be removed from the socket on the adapter, the two plug-ins on the end head of the oxygen supply tube are held and pressed inwardly, the buckles on the plug-in are dislodged from the slots, and then the oxygen supply tube is pulled out outward. The installation and removal of the external oxygen supply tube of the oxygen concentrator are very convenient, and the obliquely arranged plug-ins on the end head of the oxygen supply tube not only facilitates the insertion of the end head into the socket, but also ensures that the buckles on the plug-in are snapped outward into the slots on the slot and will not be easily dislodged.

[0020] Furthermore, a receiving groove is provided on the top of the adapter, the bottom of the socket is received in the receiving groove, and the socket and the adapter are fixed by screws. Therefore, this ensures that the socket can be firmly installed on the adapter and minimizes oxygen leakage in the socket.

[0021] The utility model also provides an oxygen concentrator, which includes the aforementioned oxygen humidification cup structure, wherein a connecting pipe is communicated with the oxygen outlet of the oxygen concentrator, and the plug socket is connected to the oxygen supply pipe.

[0022] In the oxygen concentrator of the present invention, the oxygen humidified by the cup body is directly output to the oxygen supply pipe outside the oxygen concentrator. The humidified oxygen does not need to be output back to the pipeline inside the oxygen concentrator, which can avoid condensation of water vapor carried by the humidified oxygen in the pipeline inside the oxygen concentrator, thereby ensuring the humidity of the oxygen entering the oxygen supply pipe. In addition, the oxygen supply pipe outside the oxygen concentrator is detachably connected to the adapter, and the adapter is detachably connected to the cup body. The oxygen humidification cup structure and the oxygen supply pipe outside the oxygen concentrator can be transported and stored as a whole. At the same time, it is also convenient to clean the adapter and the cup body separately to ensure hygiene and safety. BRIEF DESCRIPTION OF THE DRAWINGS

The shape of the receiving groove 27 is adapted to the outer shape of the socket 24, and the inner wall shape of the socket 24 is adapted to the shape of the end of the oxygen supply pipe outside the oxygen concentrator. The bottom of the socket 24 is accommodated in the receiving groove 27, and the socket 24 and the adapter 2 are fixed by screws. In this way, it can ensure that the socket 24 can be firmly installed on the adapter 2, and it can also be In order to minimize the leakage of oxygen in the socket 24, the top of the outlet pipe 23 is located in the socket 24, the air inlet pipe 21 is plugged into the air inlet 11, and the bottom of the outlet pipe 23 is plugged into the air outlet 12. Sealing rings (not shown) are installed on the air inlet pipe 21 and the air outlet pipe 23 to ensure the sealing of the connection. The adapter 2 is detachably connected to the cup body 1, and the adapter 2 can be directly removed from the cup cover 101 of the cup body 1. In this way, it is convenient to clean the adapter 2, the cup body 1 and the cup cover 101 separately to ensure hygiene and safety; when the oxygen humidification cup structure is installed on the oxygen concentrator, the connecting pipe 22 on the adapter 2 is connected to the oxygen outlet on the oxygen concentrator. When the oxygen concentrator is working, the oxygen produced by the oxygen concentrator enters the cup body 1 through the connecting pipe 22, the air inlet pipe 21, and the air inlet 11. The oxygen is moistened by the water in the cup body 1 and is discharged to the socket 24 through the air outlet 12 and the outlet pipe 23 in turn.

[0032] The top of the cup body 1 is provided with a convex ring 13 and a pressure relief hole 14. Figure 3 and Figure 4, the convex ring 13 and the pressure relief hole 14 are arranged on the cup cover 101 of the cup body 1, the convex ring 13, the pressure relief hole 14 and the cup cover 101 can be integrally formed, the top of the cup cover 101 is integrally formed with a convex ring 13 that protrudes upward, and the cup cover 101 is formed with a pressure relief hole 14, and the pressure relief hole 14 is located at the bottom of the space enclosed by the convex ring 13, and the side wall of the convex ring 13 is formed with a notch 131 near the top of the convex ring 13, and the top of the notch 131 is open, and the bottom of the cap body 4 is formed with a convex column 41, and the pressure relief block 5 is formed with a concave cavity 51, the cross section of the cavity 51 can be circular, the inner diameter of the cavity 51 is larger than the diameter of the protrusion 41, the bottom of the protrusion 41 is inserted into the cavity 51, the cap body 4 is covered on the top of the protrusion ring 13, in order to ensure that the cap body 4 can be firmly covered on the top of the protrusion ring 13, the top of the protrusion ring 13 is formed with a circle of bosses close to the inner wall, and the inner wall of the cap body 4 is formed with a circle of steps that adapt to the bosses on the protrusion ring 13. When the cap body 4 is covered on the top of the protrusion ring 13, the bosses on the protrusion ring 13 The platform is inserted into the cap body 4 and presses upward on the step on the inner wall of the cap body 4; since the bottom of the boss 41 is inserted into the cavity 51, the pressure relief block 5 has an upper and lower floating space at the bottom of the boss 41. When the air pressure in the cup body 1 is less than or equal to the set value, the pressure relief block 5 blocks the pressure relief hole 14 downward under the action of its own gravity. At this time, the bottom of the boss 41 does not contact the inner bottom of the cavity 51, providing floating space for the pressure relief block 5 to float upward.

In this way, when the oxygen supply pipe outside the oxygen concentrator is removed from the socket 24, the rubber cover 3 can be covered on the top of the socket 24 to prevent foreign matter or dust from entering the socket 24, ensuring hygiene and safety. When the oxygen supply pipe needs to be installed, the rubber cover 3 can be removed from the socket 24. Since the end of the belt body 31 of the rubber cover 3 is fixed on the socket 24, the rubber cover 3 will not be lost.

[0036] See Figure 1 and Figure 2 A lifting portion 32 is formed on the side of the rubber cover 3, and the rubber cover 3 can be easily removed from the socket 24 through the lifting portion 32.

[0037] See Figure 3 and Figure 4 The bottom of the cup body 1 is open, and a heat-conducting cover 102 is installed at the bottom of the cup body 1.

After the oxygen humidification cup structure is installed on the oxygen concentrator, the heating component can heat the heat-conducting cover 102 at the bottom of the cup body 1. The heated heat-conducting cover 102 can heat the water in the cup body 1. The controller of the oxygen concentrator can maintain the temperature of the water in the cup body 1 within a certain range by controlling the heating component, ensuring that the humidified oxygen maintains a certain temperature, so that the user can breathe comfortable oxygen.

[0038] See Figure 3The inner wall of the socket 24 is formed with two relatively inclined slots 241, and a card slot 2411 is formed on the slot 241. The oxygen supply pipe outside the oxygen concentrator can be installed with an end. The two sides of the end are respectively provided with plug-ins arranged obliquely and adapted to the shape of the slot 241. The plug-in is formed with a buckle adapted to the shape of the card slot 2411. In this way, the oxygen supply pipe outside the oxygen concentrator can be snapped into the card slot 2411 on the socket 24 through the buckles on the two plug-ins on the end, ensuring that the end of the oxygen supply pipe outside the oxygen concentrator can be firmly fixed. The oxygen supply tube outside the oxygen concentrator is easily removed after being plugged into the socket 24.

The oxygen is moistened by the water in the cup body 1 and then passes through the air outlet 12, the air outlet The trachea 23, the socket 24, and the oxygen supply tube are discharged to the nasal plug oxygen inhalation tube or the oxygen inhalation nasal mask for the user to breathe. The water content of the oxygen discharged from the oxygen supply tube increases, thereby realizing the humidification of the oxygen. When the oxygen supply tube is removed from the socket 24, the rubber cover 3 can be covered on the top of the socket 24 to prevent foreign matter or dust from entering the socket 24, thereby ensuring hygiene and safety. The oxygen humidification cup structure of the utility model, the oxygen humidified by the cup body 1 is directly output to the oxygen supply tube outside the oxygen concentrator, and the humidified oxygen does not need to be input back to the pipeline inside the oxygen concentrator, which can avoid the water vapor carried by the humidified oxygen in the oxygen concentrator. Condensation occurs in the pipes at the bottom of the cup body 1, ensuring the humidity of the oxygen entering the oxygen pipe. At the same time, the heating component on the oxygen concentrator can heat the heat-conducting cover 102 at the bottom of the cup body 1, and the heated heat-conducting cover 102 can heat the water in the cup body 1. The controller of the oxygen concentrator can maintain the temperature of the water in the cup body 1 within a certain range by controlling the heating component, ensuring that the humidified oxygen maintains a certain temperature, allowing the user to breathe comfortable oxygen.

It is also convenient to clean the adapter 2, the cup body 1 and the cup cover 101 separately to ensure hygiene and safety. At the same time, when the air pressure in the cup body 1 is less than or equal to the set value, the pressure relief block 5 blocks the pressure relief hole 14 downward under the action of its own gravity. When the air pressure in the cup body 1 is greater than the set value, the oxygen in the cup body 1 will push the pressure relief block 5 upward through the pressure relief hole 14, and part of the oxygen will leak out through the notch 131 on the side wall of the convex ring 13, ensuring that the pressure of the oxygen in the cup body 1 is maintained in a reasonable range.
