[0066] Note that the CPA P device 1 A has an LCD (Liquid Crystal Display) separately. ) Or an organic EL (Electro-Luminescence) display, etc. may be provided. Here, the display unit may be provided in the blower unit 100 or the humidifying unit 200 A. Further, the operation unit 1 3 1 does not have to be a button having a physical shape as shown in FIGS. 1 to 3, but may be a touch panel or the like provided on the display surface of the LCD, for example. Of the operation unit 131, the buttons other than the button for switching the power supply of CPAP device 1A to ◯N / 〇FF may be provided in the humidification unit 200A.

[0067] Here, in the first usage state, the first outlet port 1 2 2 provided in the first housing 1 10 and the connection port 2 2 1 provided in the second housing 2 10 Are connected. As a result, in the first use state, the second flow passage 2 25 is connected to the downstream side of the first flow passage 1 20.

[0068] Therefore, in the first use state, the air sucked from the first inlet port 1 2 1 is driven by the blower 1 4 0, so that the first flow passage 1 2 0 and the second flow It is discharged from the second outlet 2 2 2 via the route 2 2 5 in this order. The air discharged from the second outlet 22 2 is then sent to the airway of the user via the hose 300 and the mask 400. That is, in the first usage state, the first inlet port 1 2 1 functions as an intake port for sucking air into the CPAP device 1 A, and the second outlet port 2 2 2 functions as the CPAP device 1 2 A. It will function as an exhaust port that discharges air from the inside of 1 A.

[0069] Fig. 6 is a schematic cross-sectional view showing the connection structure of the humidifying unit and the air blowing unit in the CPAP device according to the first embodiment. With reference to FIG. 6, the connection structure between the humidifying unit 200 A and the air blowing unit 100 will be described. Specifically, the specific shapes of the connection port 2 21 and the first outlet 1 2 2 will be described.

[0070] As shown in Fig. 6, the second outlet 2222 has a first outer connecting portion R1 on the outer peripheral surface to which the hose 300 is detachably fitted. The inner diameter of the second outlet port 2 22 is larger than the inner diameter of the connection port 2 21.

[0071] The first outlet port 1 2 2 has the same outer shape as that of the first outer connecting portion R 1. 〇 2020/175032 16 卩 (: 170? 2020 /004111

It has an outer connecting portion 82 on the outer peripheral surface. The first outlet port 1 2 2 has an inner connection portion 8 3 on which the connection port 2 2 1 is removably fitted, on its inner peripheral surface.

[0072] The first outlet 1 2 2 has the first inner peripheral surface 1 2 2 the second inner peripheral surface 1 2 2

Has 1 220. The first inner peripheral surface 1 2 2 ₃ is provided on the opening end side. The inner connecting portion 3 is provided on the first inner peripheral surface 1 2 2 3 2.

The second inner peripheral surface 1 2 2 ₃ is located upstream of the first inner peripheral surface 1 2 2 _{3 in the} air blowing direction. The inner diameter of the second inner peripheral surface 1 22 2 is smaller than the inner diameter of the first inner peripheral surface 1 2 2 3. The inner diameter of the second inner peripheral surface 1 2 2 13 is substantially the same as the inner diameter of the connection port 2 2 1. The stepped portion 1 220 connects the first inner peripheral surface 1 2 2 3 and the second inner peripheral surface 1 2 2 sill.

[0074] When the humidifying unit 2800 is attached to the blower unit 100, the connection port 2 2 1 is kneaded inside the first inner peripheral surface 1 2 2 3. As described above, since the inner diameter of the second inner peripheral surface 1 2 2 匕 is almost the same as the inner diameter of the connection port 2 2 1, the second inner peripheral surface 1 2 2 Pressure loss can be reduced when air is blown. In addition, wind noise can be reduced by reducing pressure loss.

[0075] In the state where the connection port 2 2 1 is squeezed inside the first inner peripheral surface 1 2 2 3, the second inner peripheral surface 1 2 2 and the inner peripheral surface of the connection port 2 2 1 It is preferable that they are continuous. As a result, pressure loss can be reduced even at the connection end, and wind noise can be further reduced.

[0076] Further, since the first outlet port 1 2 2 has a configuration in which the connection port 2 2 1 is fitted inside, the inner diameter of the connection port 2 2 1 is smaller than that in the configuration where the connection port is fitted outside. It's getting smaller. Therefore, the flow velocity of the air blown into the mixing chamber 2 17 through the connection port 2 21 can be increased. As a result, the agitation of air in the mixing chamber 2 17 can be promoted, and the water 5 01 as fine droplets can be effectively mixed in the air. As a result, the air can be efficiently humidified.

Further, the inner diameter of the second outlet port 2 22 is larger than the inner diameter of the connection port 2 21. As a result, when the air is discharged from the mixing chamber 2 17 through the connection port 2 21 the flow velocity becomes slower than when it is introduced into the mixing chamber 2 17. this child 〇 2020/175032 17 卩(: 170? 2020/004111

Also by the above, it is possible to effectively mix the moisture 50 1 into the air introduced from the connection port 2 21.

As shown in Fig. 7, when the second outlet port 2 22 is provided on the upper surface of the second housing 210, the second outlet port 2 22 is dislocated from the axial direction of the connection port 2 21. Located in the open position. Specifically, the axial direction of the second outlet 2 2 2 may be a direction intersecting the axial direction of the connecting port 2 2 1, for example, a direction perpendicular to the axial direction of the connecting port 2 2 1. It may be. Further, the axial direction of the second outlet port 2 22 may have a relationship between the axial direction of the connection port 2 21 and the twist position.

[0079] In such a case, the air introduced into the mixing chamber 217 is directly supplied to the second outlet port.

Since it is possible to suppress the movement toward 2 2 2, it is possible to more effectively stir the air in the mixing chamber 2 17.

[0080] As shown in Fig. 6 again, the inner connecting portion 3 and the second outer connecting portion 2 are

1 The outlets 1 2 2 are provided so as to overlap each other in the radial direction. As a result, as compared with the structure in which the inner connecting portion 8 3 is provided on the upstream side of the second outer connecting portion 2 in the blowing direction, the insertion area of the connecting port 2 21 can be shortened.

[0081] Furthermore, the device 18 is sandwiched between the first outlet 1 2 2 and the connecting port 2 2 1 when the connecting port 2 2 1 is kneaded in the first outlet 1 2 2. Further, a seal part 500 is provided. The seal portion 500 is arranged between the outer peripheral surface of the connection port 2 21 and the first inner peripheral surface 1 22 8. The seal portion 500 has an annular shape and is made of, for example, a rubber member having elasticity such as packing.

[0082] As described above, by providing the seal portion 500 between the connection port 2 21 and the first outlet port 1 2 2, the first outlet port 1 2 2 is separated from the first housing 1 1 0. Even if the connection port 2 21 is provided so as to project and project from the second housing 210, it is possible to easily prevent air leakage.

[0083] The seal portion 500 is fixed to the first inner peripheral surface 1223, for example. More specifically, the seal portion 500 has an annular shape provided on the first inner peripheral surface 1 2 2 3. 〇 2020/175032 18 卩 (: 170? 2020 /004111

It is pressed into the groove. In this way, by providing the seal portion 500 near the opening end of the first outlet port 122, even if the seal portion 500 is deteriorated, the seal portion 500 can be easily formed. Can be exchanged.

[0084] Further, the first outlet 1 2 2 projects from the first housing 1 10 and the connection 2 2 1

2 By being provided so as to project from the housing 210, the first outlet 1 2 2 is provided in the annular recess in which a part of the first side 1 1 3 and the second side 2 1 3 is annularly recessed. As compared with the case where the connection port 2 21 is provided, the internal space of the first housing 1 10 and the internal space of the second housing 2 10 become wider. This makes it easier to arrange a member such as silencer _ 150 in the internal space.

[0085] FIG. 8 is a diagram showing how foreign matter is suppressed from entering at the inlet of the blower unit in the 0 device according to the first embodiment.
