Referring to fig. 2, the cup lid 11 covers the cup body 12 and encloses a humidification chamber 14, and water for humidifying oxygen can be stored in the humidification chamber 14.

As shown in fig. 1, the cup cover 11 has a pair of air exchanging joints 15 respectively communicating with the humidification chamber 14, and it can be understood that one air exchanging joint of the pair of air exchanging joints 15 enters the humidification chamber 14, and oxygen enters the humidification chamber 14 through the humidification tube 41 shown in fig. 3, and then is discharged out of the humidification chamber 14 through the other air exchanging joint of the pair of air exchanging joints 15, so as to complete the humidification of oxygen. Of course, the specific structure of the humidifying tube is not limited in the present application, as long as the humidifying of the oxygen can be completed in the humidifying cavity, for example, the humidifying tube 41 may not extend into the water, and the oxygen is humidified through the surface of the water.

Fig. 4 provides a schematic structural diagram of an oxygen generator body 20 of an oxygen generator, as shown in fig. 4, the oxygen generator body 20 has an exhaust nozzle 21 and an air return nozzle 22, the exhaust nozzle 21 and the air return nozzle 22 are arranged along the same direction, see fig. 1 simultaneously, a pair of air change connectors 15 are arranged along the same inserting direction, therefore, the humidification cup 10 can be inserted and installed along the direction of the arrow in fig. 2 directly to the direction close to the oxygen generator body 20, until the humidification cup 10 is located at the installation position, so that the pair of air change connectors 15 are respectively inserted and matched with the exhaust nozzle 21 and the air return nozzle 22, and the preliminary inserting and installing of the humidification cup 10 and the oxygen generator body 20 is completed. When the humidification cup 10 is located at the installation position, the pair of air exchange connectors 15 are respectively connected with the exhaust nozzle 21 and the air return nozzle 22 in an inserting mode and then communicated, oxygen in the oxygen generator enters water for humidification through the exhaust nozzle 21, the air exchange connectors and the humidification pipe 41, the humidified oxygen returns to the oxygen generator through the air exchange connectors and the air return nozzle 22, and the humidified oxygen is transmitted to a patient through a pipeline of the oxygen generator for use.

Through setting up a pair of joint 15 of taking a breath along the same grafting direction, can be along this grafting direction grafting can install humidifying cup 10 to the mounted position when installing humidifying cup 10 to oxygenerator body 20, easy operation, the water in the humidifying cup needs comparatively frequent change, therefore humidifying cup need often take off from the mounted position, consequently directly along the mode very convenient operation of grafting direction installation and dismantlement, can try to be used for the user demand of frequent loading and unloading. And the ventilation joint 15 of the humidification cup 10 can form an oxygen loop with the oxygen generator body 20, and oxygen enters the humidification chamber 14 from the oxygen generator and then returns to the oxygen generator, so that the humidification cup 10 does not need an external pipeline, the operation of connecting the pipeline to the humidification cup 10 by a user is cancelled, and the operation steps of the user are reduced. Meanwhile, the possibility that the humidifying cup is connected with the oxygen generator body to fail due to the fact that a user mistakenly touches the external pipeline is reduced or even avoided.

With continuing reference to fig. 1 and 2, the humidification cup 10 further comprises a latch 13 having a locking portion 131, the locking portion 131 shown in fig. 2 is located at the locking position, the locking portion 131 is embedded in the detachment preventing portion 23 of the oxygen generator body 20, and the detachment preventing portion 23 can limit the humidification cup 10 from being detached from the installation position in a direction opposite to the direction of the arrow in fig. 2 by abutting against the locking portion 131. When the locking part 131 is moved downward in fig. 2 to be out of the abutment of the slip-off preventing part 23, the humidifying cup 10 can be moved in the direction opposite to the arrow direction in the figure to be separated from the oxygen generator body 20.

Through setting up fastener 13, can restrict the humidifying cup 10 that is located the mounted position, in order to restrict humidifying cup 10 and can break away from the mounted position easily, and then make the exhaust nozzle of taking a breath joint and oxygenerator body, return the air nozzle only realize sealed effect can, need not to restrict the removal of humidifying cup through too tight interference fit, therefore, the user only needs to make the closure portion of fastener remove to the unblock position from the closure position, can take out the humidifying cup from the mounted position easily, when the humidifying cup is pegged graft to the oxygenerator body, when taking a breath joint and exhaust nozzle peg graft, the closure portion of fastener cooperates so that the humidifying cup is located the mounted position with the portion of taking a breath of oxygenerator body. Moreover, the plugging of the ventilation joint, the exhaust nozzle and the air return nozzle can be kept stable and effective for a long time through the matching of the clamping piece and the anti-dropping part.

In the embodiment shown in fig. 2, the retaining portion 23 is a groove, and the locking portion 131 is a protrusion, and the locking portion 131 is inserted into the retaining portion 23 through the locking portion 131 to complete the locking of the locking portion 131 and the retaining portion 23. Of course, the locking part and the anti-slip part can adopt other locking modes as long as the anti-slip part can limit the position of the locking part.

In an alternative implementation manner of the engaging member, as can be seen in fig. 1, fig. 2 and fig. 5, the engaging member 13 has an operating portion 132, and the operating portion 132 and the locking portion 131 are located on the same extension arm of the engaging member 13, so that the operating portion 132 can drive the locking portion 131 to move downward from the locking position in fig. 2 to the unlocking position, and a user can press the operating portion 132 with a finger when gripping the cup body 12, so that the operating portion 132 can drive the locking portion 131 to move. As shown in fig. 5, the front end surface of the locking portion 131 may be configured as an inclined surface, so when a user installs the humidification cup 10 to the installation position, the support portion 24 of the oxygen generator body 20 may actively guide the locking portion 131 to be located at the unlocking position, and as the humidification cup 10 continues to move to the installation position, until the locking portion 131 moves to the locking position matching with the anti-release portion 23, the installation of the humidification cup 10 is completed, and the user only needs to hold the cup body 12 or the cup cover 11 to complete the installation, which is simple in operation. When the humidification cup 10 needs to be taken down from the installation position, a user can hold the cup cover 11 or the cup body 12, and simultaneously press the operation part 132 with one finger, so that the locking part is separated from the locking position, the humidification cup 10 can be taken out, water changing and other operations are carried out, and the operation is simple.

Of course, the manner in which the operation portion drives the locking portion to move is not limited to the manner in which the operation portion moves up and down, and it can be understood by those skilled in the art that the operation portion can drive the locking portion to move horizontally to lock the locking portion and the disengagement preventing portion, and the horizontal movement drives the locking portion to move from the locking position to the unlocking position, so that any manner in which the operation portion drives the locking portion to move between the locking position and the unlocking position is within the scope of the present application.

The latch is further optimized in that, as shown in fig. 1, 2 and 5, the latch 13 further has a resilient support 133 connected to the locking portion 131, and as shown in fig. 5, the latch 13 has two extending arms, and the two extending arms can support each other, that is, the extending arm at the lower side can support the support arm at the upper side and has a tendency to move upward, and the locking portion 131 and the operating portion 132 are located on the extending arm at the upper side, and the extending arm at the lower side forms the resilient support 133, so that the latch 13 can be mounted on the cup lid 11, and the locking portion 131 and the operating portion 132 can extend out of the hole on the cup lid 11 through the support of the resilient support 133, so that the locking portion 131 abutted by the retaining portion 23 can limit the movement of the humidification cup through the sidewall of the abutting hole. In a natural state, the elastic support portion 133 supports the locking portion 131 in the state shown in fig. 1, so that the elastic support portion 133 can support the locking portion 131 in the locking position when the humidification cup 10 is installed in the installation position, and similarly, when the locking portion 131 is located in the unlocking position by pressing the operation portion 132 and then the pressing is released, the elastic support portion 133 can support the locking portion 131 to return to the locking position, thereby maintaining the continuous and stable locking.

Of course, as will be understood by those skilled in the art, the elastic support portion may be an independent elastic body, such as a spring, besides being integrally formed with the operation portion, one end of the elastic body is fixedly connected to the cup cover, and the other end of the elastic body is connected to the locking portion, so as to realize the pushing action of the locking portion.

In an alternative embodiment of the humidification cup, as shown in fig. 1, the cup cover 11 is provided with an insertion portion 111 arranged along an insertion direction, the insertion portion 111 encloses an insertion cavity 112, and the pair of air exchange connectors 15 are arranged in the insertion cavity 112. Corresponding to the insertion part 111, see fig. 3 and 4, the oxygen generator body 20 has a support part 24, the exhaust nozzle 21 and the air return nozzle 22 are located in the support part 24, the support part 24 can be inserted and matched with the insertion part 111, specifically, in a specific embodiment, the inner side wall of the support part 24 is abutted to the outer side wall of the insertion part 111, when the humidification cup 10 is inserted, the inner side wall of the support part 24 can provide a guiding function for the insertion part 111, the guiding function can enable the insertion of the air exchange connector 15 with the exhaust nozzle 21 and the air return nozzle 22 to be more accurate, on the other hand, the movement of the humidification cup 10 can be limited in the direction perpendicular to the insertion direction, and further the air exchange connector 15 and the exhaust nozzle 21 which are inserted and connected with each other are prevented from rotating relatively to affect the air tightness. The engaging member 13 can also be disposed in the inserting cavity 112, and the locking portion 131 extends upward from the hole formed by the inserting portion 111, so that the structure is compact, and the locking portion can be locked with the disengagement preventing portion more stably because the inserting portion and the supporting portion do not move relatively in the vertical direction after being inserted into each other.

The further optimization of the matching of the insertion part 111 and the support part 24 is that, as shown in fig. 3, the insertion part 111 and the support part 24 are inserted to form a closed ventilation cavity 25, i.e. the outer side wall of the insertion part 111 can be attached to the inner side wall of the support part 24, the ventilation joint 15 is inserted into the ventilation cavity 25 together with the exhaust nozzle 21 and the air return nozzle 22, and the ventilation cavity 25 is separated from the outside, so that the insertion part of the ventilation joint 15 and the oxygen generator body 20 can be closed, and is not polluted or affected by external factors, and meanwhile, the closed ventilation cavity can reduce the leakage of oxygen to the outside as much as possible, thereby further ensuring that the oxygen can be fully utilized.

Referring to fig. 9, the cap 11 further includes a pressure relief passage 16, the pressure relief passage 16 is communicated with the wetting chamber 14 through a pressure relief hole 18, a pressure relief member 17 is shown in a blocking position in fig. 9, and the pressure relief member 17 blocks the pressure relief hole under the action of gravity. When oxygen in the humidification cavity 14 can not be discharged, and the pressure in the humidification cavity 14 is increased, the pressure pushes the pressure release part 17 upwards to the opening position, and the humidification cavity 14 is communicated with the pressure release channel 16 when the pressure release part 17 is located at the opening position, so that the pressure release of the humidification cavity 14 is realized, and when the pressure in the humidification cavity 14 is normal, the pressure release part 17 is located at the blocking position to prevent the oxygen from leaking from the pressure release hole 18. The pressure relief member can therefore keep the pressure in the humidification chamber 14 relatively constant. Meanwhile, when the pressure relief piece 17 is located the open position, when oxygen is discharged through the gap between the pressure relief hole 18 and the inner wall of the pressure relief piece 17 and the inner wall of the pressure relief channel 16, the oxygen flows through the gap rapidly to cause disordered flow, so that the oxygen can vibrate to emit obvious sound, further the pressure in the humidification cup 10 of the user is reminded to increase, the user can find and check the reasons in time, the potential safety hazard that the oxygen can not be normally output to the patient can be found in time, the danger of the patient caused by oxygen deficiency can be avoided as far as possible, and the treatment or recuperation effect can be ensured.

In an alternative implementation manner of the oxygen generator, referring to fig. 2 or fig. 3, the oxygen generator body 20 has a mounting groove 26, a supporting surface 261 is formed on a bottom surface of the mounting groove 26, when the humidification cup 10 is located at the mounting position, the supporting surface 261 can be upwards abutted against the cup body 12 of the humidification cup 10, and a supporting force of the supporting surface 261 can offset the gravity of the humidification cup 10 to a certain extent, so as to reduce a vertical force between the insertion part 111 and the supporting part 24. Meanwhile, the supporting surface 261 can also play a certain degree of guiding role, when the humidification cup 10 is installed to the installation position, the bottom of the cup body 12 can be firstly lapped on the supporting surface 261 to complete preliminary installation, then the insertion part 111 is aligned with the supporting part 24, and the humidification cup 20 is moved along the insertion direction to complete installation.

A further optimization of the mounting groove 26 is that the depth of the mounting groove 26 in the plug-in direction of the wetting cup 10 is not more than one third of the diameter of the cup body 12. Referring to fig. 2, the depth L of the mounting groove 26 is less than one third of the diameter R of the cup body 12, and referring to fig. 6, the depth L is not greater than R, which facilitates the grasping of the portion of the cup body 12 exposed outside the mounting groove 26 by a user, thereby facilitating the user to complete the assembly and disassembly of the humidification cup 10.

Another optimization to mounting groove 26 lies in, is formed with brace 42 along the circumferential direction of cup in the mounting groove 26, but brace 42 on the one hand butt cup is in order to prevent that the cup from taking place to rock about, but on the other hand brace can butt cup make and have the gap between cup and the mounting groove, and then convenience of customers's the operation of snatching. And the butting of the limiting ribs on the cup body can limit the inserting depth of the humidification cup, so that the humidification cup is located at the optimal position.

In the insertion fit manner of the ventilation joint 15 with the exhaust nozzle 21 and the air return nozzle 22, the ventilation joint 15 can be directly sleeved with the exhaust nozzle 21 and the air return nozzle 22 for insertion fit. Or in another embodiment, the oxygen generator body 20 and the humidification cup 10 are in plug fit through the flexible connector 30. Referring to fig. 7 and 8, the flexible connection member 30 includes a first passage 31 and a second passage 32, when in use, the first passage 31 and the second passage 32 of the flexible connection member 30 can be firstly sleeved on the pair of ventilation connectors 15, referring to fig. 10, and then the humidification cup 10 is installed on the oxygen generator body 20 along the insertion direction thereof, so that the first passage 31 and the second passage 32 of the flexible connection member 30 are respectively sleeved on the exhaust nozzle 21 and the air return nozzle 22, referring to fig. 3, wherein the ventilation connectors 15, the exhaust nozzle 21 and the air return nozzle 22 with the same caliber can be selected, when in insertion, the ventilation connectors 15 can be abutted against the exhaust nozzle to give a user feedback that the humidification cup is already installed, and the problems of detachment or oxygen leakage caused by tight or loose insertion of the humidification cup 10 into the oxygen generator body 20 can be avoided as much as possible.

Through setting up flexible connection spare 30, can make flexible connection spare 30 and the 15 interference fit of joint of taking a breath, flexible connection spare 30 and exhaust nozzle, suction nozzle interference fit simultaneously can increase the interference fit seal area of grafting cooperation department to make oxygen be difficult for leaking from grafting department. And the end part of the flexible connecting piece can be arranged into a structure with an expanded end part as shown in figure 3, so that the expanded structure can play a certain guiding plugging role during plugging, the plugging fault-tolerant rate is higher, and the plugging success rate is further improved. Meanwhile, the first passage and the second passage are combined on the flexible connecting piece, so that the probability of successful splicing of the pair of air exchange connectors with the air exhaust nozzle and the air inlet nozzle can be improved, and the adverse effects on splicing caused by the deformation of the pair of air exchange connectors, the air exhaust nozzle or the air return nozzle can be reduced or overcome.

In a specific implementation mode, the flexible connecting piece can be integrated with the air exchange joint of the humidification cup in an injection molding mode, or the flexible connecting piece is integrated with the exhaust nozzle and the air inlet nozzle of the oxygen generator in an injection molding mode, one end, which is used for plugging, of the flexible connecting piece is provided with an outward chamfer so as to form an expansion structure, and therefore the flexible connecting piece can be fixed stably when the flexible connecting piece plays a good guiding plugging effect, and further the flexible connecting piece is prevented from dropping and losing effects. In another specific embodiment, the end part of the air exchange joint can be directly provided with an outward chamfer, and the air exchange joint is directly inserted with the exhaust nozzle and the air inlet nozzle in a guiding way through the chamfer.
