Detailed Description

The following detailed description of embodiments of the utility model is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the utility model is not limited to the specific embodiments.

Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.

As shown in fig. 1, a humidifying cup 100 according to an embodiment of the present utility model includes a cup body 10, a cup cover 20, and a ventilation structure 30.

Wherein, a humidifying space with an open top is formed in the cup body 10, the cup cover 20 covers the opening of the cup body 10, and the ventilation structure 30 is arranged on the cup cover 20 and comprises an air inlet pipe 31 and an air outlet pipe 32 which are communicated with the humidifying space in the cup body 10. When the air inlet pipe 31 and the air outlet pipe 32 are arranged on the cup cover 20 and are connected with an external oxygen generator, the cup body 10 can be directly separated from the cup cover 20 when water in the cup needs to be replaced, the whole humidifying cup 100 does not need to be separated from the oxygen generator, and the operation steps are simplified.

A bypass hole 3111 is formed on the air inlet pipe 31 to prevent water in the humidifying cup 100 from flowing back to the oxygenerator due to excessive internal and external pressure difference of the humidifying cup during switching of the oxygenerator or due to other reasons, so that the oxygenerator is failed or even damaged, and the bypass hole 3111 is located in the humidifying space.

As shown in fig. 2, the air inlet pipe 31 includes an inner pipe 311 and a branch pipe 312 which are connected, wherein the branch pipe 312 is disposed in the humidification space, one end of the inner pipe 311 passes through the cup cover 20 and extends out of the humidification space, and a bypass hole 3111 is opened on the inner pipe 311.

In this embodiment, the branch pipe 312 may be extended into the water in the cup body 10 through a connected hose or a hard pipe, and oxygen flows through the branch pipe 312 through the inner pipe 311, is introduced into the water through the connected hose or hard pipe, is humidified, enters the humidification space, and is output through the air outlet pipe 32.

In fig. 2, the bypass hole 3111 is provided at the end of the inner tube 311, so that it is possible to prevent the water in the humidifying cup 100 from flowing back to the external oxygenerator when the oxygenerator is turned on or off, or even damaged during use.

Further, in order to prevent the hose connected to the branch pipe 312 from being bent to affect the use effect, the branch pipe 312 is disposed perpendicular to the inner pipe 311 and parallel to the axial direction of the cup body 10. This arrangement ensures that the hose is in a straight position communicating the manifold 312 with the water in the bowl 10, ensuring that the interior of the hose is clear and that the transfer of oxygen is not affected by folding.

Meanwhile, a pressure relief pipe 21 is further arranged on the cup cover 20, a pressure relief channel is arranged in the pressure relief pipe 21 and used for communicating the inside and the outside of the humidifying space, and a gravity block 211 capable of axially moving is arranged in the pressure relief channel. Specifically, when a fault occurs, a pressure difference exists between the inside and the outside of the humidifying cup 100, when the internal pressure is too high, the gravity block 211 is jacked up upwards, part of oxygen flows out through the pressure release channel, the pressure difference between the inside and the outside is recovered, the gravity block 211 falls under the action of gravity and blocks the pressure release channel, and the humidifying cup 100 can only be communicated with the outside through the air inlet pipe 31 and the air outlet pipe 32.

As shown in fig. 2, the pressure release channel communicates with the humidification space through the hole 212. In a preferred embodiment, the aperture of the aperture 212 is smaller than the aperture of the pressure relief channel. In this arrangement, the working accuracy of the pressure relief tube 21 can be improved, and the hole 212 is provided at the bottom of the pressure relief tube 21.

Meanwhile, the pressure relief passage communicates with the external space through the window 213. In fig. 1, the window 213 is provided on the side wall of the pressure relief tube 21 outside the humidification space.

Preferably, a sound prompting device (not shown) can be arranged at the window, and when the internal oxygen flows out, the prompting device can make a sound to remind an operator that the oxygen generator may have a fault and needs to be overhauled.

It should be appreciated that the weight 211 is not preferably configured to be too heavy to be lifted, resulting in excessive internal and external pressure differentials across the humidifying cup 100, separation of the cup 10 from the cap 20, or other failure.

As shown in fig. 1 and 2, a pointed cone 2111 is provided at the top of the gravity block 211, and a limiting hole 2112 extending upward is provided at the top of the pressure release channel in cooperation with the pointed cone 2111 to limit the movement of the gravity block 211.

Specifically, the cup cover 20 is fixed with the cup body 10, in this embodiment, a threaded fixing mode is adopted, that is, engaged threads are arranged on the contact surface of the cup cover 20 and the cup body 10, and the cup body 10 is rotated to fix with the cup cover 20. In other embodiments, a snap fit or other means of securing may be used, and the present embodiment is not limited.

As shown in fig. 3, the present embodiment further provides an oxygenerator 200, which includes the above-described humidifying cup 100. An oxygen inlet hole 220 and an oxygen delivery hole 210 are formed in the outer wall of the oxygen generator 200, an air inlet pipe 31 on the humidifying cup 100 is inserted into the oxygen inlet hole 210, and an air outlet pipe 32 is inserted into the oxygen inlet hole 220. Oxygen generated by the oxygenerator 200 during operation flows into the humidifying cup 100 through the oxygen transferring hole 210 and the air inlet pipe 31, is humidified by water in the cup, and then is transferred back to the oxygenerator 200 through the air outlet pipe 32 and the oxygen inlet hole 220, and is supplied to a user.

Preferably, in order to improve the fixing effect of the humidifying cup 100 and the oxygenerator 200, the ends of the air inlet pipe 31 and the air outlet pipe 32 are provided with the protruding parts 33, as shown in fig. 2, so that a larger friction force can be provided when the humidifying cup is inserted into the oxygenerator 200, the humidifying cup is better fixed in the oxygenerator 200, and the humidifying cup 100 is prevented from falling off during movement.
