The outer wall of the electric valve 401 is fixedly connected with a transmission wire, and the bottom of the transmission wire is fixedly connected with a liquid level sensor 402, so that the liquid level sensor 402 controls the electric valve 401 through the transmission wire, and the outer wall of the liquid level sensor 402 is fixedly connected with a ring body 403, so that the liquid level sensor 402 is driven to move simultaneously during the vertical movement of the ring body 403, and an adjustment mechanism 5 is provided on the ring body 403.

[0034] Reference Figure 3 The adjustment mechanism 5 includes a guide rod 501, the top of the guide rod 501 is fixedly connected to the top outer wall of the humidification tank 2, and the bottom of the guide rod 501 is fixedly connected to the top of the base 1, so that the humidification tank 2 and the base 1 provide a supporting and fixing effect for the guide rod 501 and the caliper 502, the outer wall of the guide rod 501 is slidably connected to the ring body 403, and cooperates with the caliper 502 and the guide rod 501 to ensure the stability of the ring body 403 during vertical movement, the top outer wall of the humidification tank 2 is fixedly connected with the caliper 502, and the bottom of the caliper 502 is fixedly connected to the top of the base 1.

[0035] Reference Figure 4-Figure 5 The outer wall of the ring body 403 is fixedly connected to the sliding shell 503, and the inner wall of the sliding shell 503 is slidably connected to the outer wall of the caliper 502, so as to keep the inner wall of the sliding shell 503 moving vertically along the outer wall of the caliper 502. The outer wall of the sliding shell 503 is rotatably connected to the inner rod 504, and the outer wall of the inner rod 504 is fixedly connected to the clamping block 510, so that the inner rod 504 drives the clamping block 510 to rotate, and the outer wall of the clamping block 510 is clamped with the protrusion set on the outer wall of the caliper 502, so as to achieve the effect of fixing the vertical position of the sliding shell 503, the outer wall of the clamping block 510 is fixedly connected to one end of the spiral spring 7, and the other end of the spiral spring 7 is fixedly connected to the inner wall of the sliding shell 503, and the clamping block 510 is kept in a horizontal state by the force of the spiral spring 7.

[0036] Reference Figure 4-Figure 5The outer wall of the inner rod 504 is slidably connected with a sleeve 505, and the sleeve 505 can move laterally along the outer wall of the inner rod 504. The outer wall of the sleeve 505 is fixedly connected to the limiting block 508, and the outer wall of the sliding shell 503 is fixedly connected to the limiting cylinder 509. The outer wall of the limiting cylinder 509 is provided with a limiting groove, and the outer wall of the limiting block 508 is plugged into the inner wall of the limiting groove. By plugging, the sleeve 505 is fixed by the limiting block 508, and the inner rod 504 and the block 510 are also fixed. The inner wall of the sleeve 505 is connected to the reset spring 5 06 is fixedly connected, and the other end of the reset spring 506 is fixedly connected to the outer wall of the inner rod 504. With the force of the reset spring 506, the sleeve 505 is kept moving inward, so that the limit block 508 set on the outer wall of the sleeve 505 is kept in an inserted and fixed state with the limit groove. The inner wall of the sleeve 505 is fixedly connected with a rectangular block 507, and a sliding groove is provided at one end of the inner rod 504. The inner wall of the sliding groove is slidably connected with the outer wall of the rectangular block 507, so that when the sleeve 505 is fixed, the inner rod 504 cannot rotate due to the design of the rectangular block 507.

[0037] Working principle: During the use of the humidification tank 2, in cooperation with the water replenishment mechanism 4, the liquid level stored in the inner wall of the humidification tank 2 is sensed by the liquid level sensor 402, and when the liquid level is lower than the sensing height of the liquid level sensor 402, the electric valve 401 is controlled to open through the transmission wire, so that the liquid in the water replenishment pipe 3 is discharged downward to the inner wall of the humidification tank 2, thereby achieving the effect of automatic water replenishment.

[0038] At the same time, considering that different patients can adjust the water replenishment level of the water replenishment mechanism 4 according to their own needs when using the humidification tank 2, the user pulls the sleeve 505 outward to separate the limit block 508 set on the top of the sleeve 505 from the inner wall of the limit cylinder 509, thereby achieving the purpose of releasing the fixing effect of the sleeve 505, and vertically moving the sliding shell 503 to make the sliding shell 503 move vertically along the outer wall of the caliper 502. Since the fixing effect of the sleeve 505 and the inner rod 504 is released, during the vertical movement of the sliding shell 503, the outer wall of the block 510 will be aligned with the inner wall of the caliper 502. The outer wall is squeezed and rotated, so that the protrusion set on the outer wall of the caliper 502 and the rotated block 510 are misaligned and passed, so as to achieve the effect of changing the vertical position of the sliding shell 503 and the liquid level sensor 402. After adjusting to a suitable height, by loosening the sleeve 505, the reset spring 506 drives the sleeve 505 to reset inward, so that the limit block 508 on the outer wall of the sleeve 505 is plugged into the limit cylinder 509, so as to achieve the effect of limiting and fixing the inner rod 504 and the block 510, thereby ensuring the stability of the vertical position of the sliding shell 503 after adjustment, and facilitating the adaptation of different patients.

[0039] After passing through, the force of the spiral spring 7 drives the block 510 to rotate and reset. During the vertical adjustment of the sliding shell 503, the block 510 keeps colliding and rotating with the caliper 502, providing a certain sense of frustration, further ensuring the accuracy when adjusting the sliding shell 503.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
