Detailed ways

The utility model will be further described below in conjunction with accompanying drawing.

FIG. 1 shows a humidifier 10 for a ventilator according to the present invention. The humidifier 10 is used to humidify the breathable gas discharged from the blower device, so that the user can inhale the breathable gas with a fixed humidity, thereby making him feel comfortable.

As shown in FIGS. 1 , 3 and 4 , the humidifier 10 includes a channel carrier 7 . The channel carrier 7 can be in the shape of a tube, a cuboid or other shapes, and it is made of materials such as resin, plastic, ceramics, metal or glass. Channels 6 are formed in channel carrier 7 . The channel 6 can be straight, curved, spiral or S-shaped, etc. The channel 6 is connected with the air outlet of the blower device of the ventilator, so as to receive the breathable gas discharged from the blower device. The cross-street surface of the channel 6 can be circular, polygonal or other shapes, and the breathable gas discharged from the blower device flows inside it. Wherein, the fan device is well known to those skilled in the art and will not be described in detail here.

In order to realize the humidification function of the humidifier 10 , the humidifier 10 also includes a tubular heating element 8 embedded in the channel 6 , and a liquid supply unit 9 for supplying liquid to the inner surface of the tubular heating element 8 . Wherein, the tubular heating element 8 is a common electric heater, a flexible electric heater or a tube formed by winding resistance wires. For the convenience of installation, the tubular heating element 8 is preferably a flexible electric heater. The flexible electric heater is preferably a polyimide film electric heater.

In the prior art, the heater at the bottom of the water tank of the humidifier is used to heat the water in the entire water tank, so that the heating rate becomes slower, the evaporation rate becomes slower, the heat loss increases, and electric energy is wasted. Under the same power condition, since the tubular heating element 8 of the humidifier 10 of the present invention heats less water, it has a higher heating rate and evaporation rate than the prior art, thereby reducing heat loss, Then make full use of electric energy. Thus, the humidifier 10 is capable of evaporating a large amount of liquid in a short period of time to meet the required humidity of the breathable gas.

As shown in FIG. 1 , the liquid supply unit 9 may include a liquid source 901 (such as a water source) and a liquid supply component 902 . The liquid supply assembly 902 is used to continuously and evenly arrange the liquid in the liquid source 901 on the inner surface of the tubular heating element 8 . In one embodiment, the liquid supply assembly 902 may be a nozzle connected to a pump. In another embodiment, the liquid supply assembly 902 includes a liquid suction and water supply pipe 902a attached to the inner surface of the tubular heating element 8, and a suction pipe 902a for sucking liquid from the liquid source 901 and supplying it to the liquid suction and water supply pipe 902a. Liquid member 902b. The liquid suction supply mode is more suitable for the tubular heating element 8 than the spray liquid supply mode, because the liquid in the liquid suction replenishment pipe 902a can automatically inhale the required liquid through the liquid suction member 902b after evaporation, thereby helping to save Energy; and the spray liquid supply method not only needs to spend extra electric energy, but also needs to strictly control the spray liquid volume of the nozzle.

In one embodiment, one end of the liquid absorbing member 902b is connected to the water absorbing and replenishing pipe 902a, while the other end penetrates the tubular heating element 8 and the channel carrier 7 in the radial direction and extends into the liquid source 901, which is shown in Fig. 1 and Fig. 2 shows at the same time. In this way, the liquid suction and replenishment pipe 902a and the tubular heating element 8 can be fixed in the channel carrier 7 to a certain extent. The tubular heating element 8 includes a positioning structure (not shown) provided on the inner wall for positioning the liquid suction and replenishment pipe 902a. The positioning structure includes protrusions respectively provided at both ends of the liquid suction and replenishment pipe 902 a and fixedly connected to the inner wall of the tubular heating element 8 .

In the embodiment shown in Fig. 3, the length of the liquid suction and replenishment pipe 902a is shorter than the length of the tubular heating element 8, thereby preventing the liquid supplied by the liquid absorption and replenishment pipe 902a from flowing from both ends of the tubular heating element 8. Walk. The liquid absorption and replenishment pipe 902a and the liquid absorption member 902b can be integrally formed by sponge or water absorption fiber material, of course, they can also be formed in a separate structure. Compared with the split-type structure, the one-piece structure has a better liquid absorption effect, and can save production costs at the same time.

Wherein, the air inlet pipe 3 can be connected with the air outlet of the blower device, and the air outlet pipe 4 is connected with the user's nasal cavity and/or oral cavity through the breathing mask assembly. The respiratory mask assembly is well known to those skilled in the art and will not be described in detail here.

In this embodiment, the outlet of the air inlet pipe 3 and the inlet of the air outlet pipe 4 are connected through the channel 6 of the channel carrier 7, that is, the two ends of the channel carrier 7 are respectively fixedly sleeved on the outlet end of the air inlet pipe 3 and the outlet end of the air outlet pipe 4. outside the end of the inlet end, so that the channel carrier 7 can be fixed between the inlet pipe 3 and the outlet pipe 4 . Through these two methods, on the one hand, the communication between the ventilator and the breathing mask assembly can be realized, and on the other hand, the tubular heating element 8 can be positioned between the air inlet pipe 3 and the air outlet pipe 4 .

In an embodiment not shown, one end of the channel carrier 7 is fixed to the outlet end of the air inlet pipe 3 , and the other end communicates with the inlet end of the air outlet pipe 4 through the accommodation chamber 5 above the liquid surface. In another embodiment not shown, one end of the channel carrier 7 is fixed to the inlet end of the air outlet pipe 4 , and the other end communicates with the outlet end of the air inlet pipe 3 through the accommodation chamber 5 above the liquid surface. Through these two methods, the communication between the ventilator and the breathing mask assembly can also be realized.

Compared with the prior art, the humidifier 10 for a ventilator according to the present invention has a higher heating rate and evaporation rate, thereby reducing heat loss and making full use of electric energy. Thus, the humidifier 10 for a ventilator according to the present invention can promote the evaporation of a large amount of liquid in a short period of time, thereby satisfying the required humidity of the breathable gas.

In addition, the utility model provides a ventilator including the above humidifier 10 .
