Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1 to fig. 3, which are schematic structural views of the anti-backflow humidification water tank of the breathing machine provided by the present invention. The anti-backflow humidifying water tank of the respirator comprises an upper cover 10, a lower cover 20 fixedly connected with the upper cover 10, a sealing strip 30 arranged at the joint of the upper cover 10 and the lower cover 20, a plurality of buckles 40 rotatably connected with the upper cover 10, a heating plate 50 fixedly connected with the lower cover 20, and a sealing ring 60 arranged between the lower cover 20 and the heating plate 50 and fixedly connected with the lower cover 20. It is conceivable that the anti-backflow humidification water tank of the ventilator further includes other functional modules, such as connecting components, assembling components, etc., but these are well known to those skilled in the art and will not be described in detail herein.

The upper cover 10 includes a ladder face 11, one set up in air inlet 12 on the ladder face 11, one set up in gas outlet 13 on the ladder face 11, one set up in the upper cover 10 orientation the guiding device 14 of lower cover 20 one side, and a plurality of set up in the upper cover 10 orientation the domatic 15 of lower cover 20 one side. The ladder face 11 is a plane, the upper cover 10 passes through the ladder face 11 and outside inlet channel and outlet channel butt, in order to realize the breathing machine prevent flowing backward the outflow of the dry air current of the entering of humidifying water pitcher and humidifying air current. The air inlet 12 is used for the external drying air to enter the humidifying water tank. The air outlet 13 is used for discharging wet hot air flow in the humidifying water tank. The air inlet 12 with the gas outlet 13 set gradually in the middle part of ladder face 11 to when the humidifying water pitcher is inclined or when rocking, the wet and hot water in the anti-flowing backward humidifying water pitcher of breathing machine is difficult to follow the air inlet 12 gets into in the breathing machine, just the wet and hot water in the anti-flowing backward humidifying water pitcher of breathing machine is difficult to follow gas outlet 13 gets into patient's end, thereby reaches the effect of preventing flowing backward. The flow guiding device 14 includes a flow guiding block 141 disposed between the air inlet 12 and the air outlet 13. The flow guide block 141 extends towards the direction of the air outlet 13, so that the air flow can flow along the flow guide block 141 after entering from the air inlet 12, and flows out from the air outlet 13 after being mixed with the damp and hot water, thereby achieving the effect of humidifying the air flow. The guide block 141 plays a role of guiding the air flow. The slope surface 15 is respectively connected with the air inlet 12 and the air outlet 13. When water reaches the high side of position that upper cover 10 with step surface 11 is connected and with the internal surface that lower cover 20 set up relatively, domatic 15 can guide water to the upper cover with the low side of position that step surface 11 is connected and with the internal surface that lower cover 20 set up relatively flows, thereby can not follow air inlet 12 with gas outlet 13 flows, thereby further prevents that the water in the humidifying water pitcher from flowing backward. Because the air inlet 12 with the air outlet 13 set up in the middle part of ladder face 11 domatic 15's drainage and water conservancy diversion piece 141 can lead the humid air current the air outlet 13 can not follow the air inlet 12 water conservancy diversion, thereby work as during the slope of humidifying water pitcher sets up, in this embodiment, humidifying water pitcher inclination is 20 degrees humidifying water pitcher is rotatory 360 degrees around its central axis and can not appear water and follow air inlet 12 or the air outlet 13 flows.

The lower cap 20 is shaped to match the upper cap 10. The lower cover 20 may include a plurality of ribs engaged with the plurality of hooks 40 in a one-to-one correspondence, an inner cavity for containing water, and an opening for installing the heating plate 50. The lower cover 20 is provided with a graduation line 21 for limiting the water level of the lower cover, in this embodiment, the graduation line 21 includes a 100% graduation line and a 50% graduation line, and the graduation line 21 is provided at one side of the lower cover 20 for limiting the water level of the water added in the lower cover 20.

The sealing strip 30 is used for connecting the upper cover 10 and the lower cover 20 to prevent air leakage at the connection between the upper cover 10 and the lower cover 20. The sealing tape 30 may be rubber, paper, metal, or plastic.

The clip 40 is used for fixing the upper cover 10 and the lower cover 20 and preventing the relative movement between the upper cover 10 and the lower cover 20.

The heating plate 50 is used to convert electrical energy into heat energy to heat the water in the humidification water tank to a temperature at which the patient feels more comfortable when the patient absorbs the hot and humid water vapor.

The sealing ring 60 is used to connect the lower cover 20 and the heating plate 50 to prevent the water in the humidification water tank from overflowing between the lower cover 20 and the heating plate 50. The seal ring 60 may be rubber, paper, metal, or plastic.

The lower cover 20, the sealing ring 60 and the heating plate 50 are connected by bolts.

Compared with the prior art, the utility model provides a breathing machine prevent flowing backward humidifying water pitcher is through setting up an air inlet 12 to and a gas outlet 13, just air inlet 12 with gas outlet 13 set gradually in the middle part of ladder face 11, thereby when the water level of lower cover 20 is located scale mark 21, work as when breathing machine prevent flowing backward the humidifying water pitcher by the slope, breathing machine prevent flowing backward the wet hot water in the humidifying water pitcher difficult follow air inlet 12 gets into in the breathing machine, just breathing machine prevent flowing backward the wet hot water in the humidifying water pitcher difficult follow gas outlet 13 gets into patient's end, thereby reaches the effect of preventing flowing backward. Meanwhile, the arrangement of the flow guide block 141 enables the air flow to flow along the flow guide block 141 after entering from the air inlet 12, and the air flow is mixed with the damp and hot water and then flows out from the air outlet 13, so that the situation of backflow from the air inlet 12 cannot occur, and the backflow is further prevented.

The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
