Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The utility model is further described below in conjunction with embodiments.

[0033] The terms “left”, “right”, “front”, “back”, “up” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0034] Example 1

[0035] Please refer to the instruction manual Figure 1-8 A humidification device for a ventilator includes a shell 1, a heating mechanism 6 and a water storage mechanism 3.

[0036] One side of the housing 1 is open and the other side is provided with a pipeline mechanism 2 .

[0037] Specifically, the pipeline mechanism 2 includes a pipeline 21, a hose 22 and a clamping plate 25. The pipeline 21 is installed on the shell 1, one end of which is located inside the shell 1, and the other end passes through the outside of the shell 1 and is provided with a retaining ring 26. One end of the hose 22 is movably inserted on the outside of the other end of the pipeline 21 and can abut against the retaining ring 26, and a limiting ring 23 is provided on the outside of this end. A plurality of clamping plates 25 are evenly distributed on the outer side of the limiting ring 23 in the circumferential direction. The clamping plates 25 are connected to the outer side of the limiting ring 23 through elastic connecting blocks 24, and the clamping plates 25 are bent inward in a hook shape near the end of the pipeline 21.

[0038] By putting the hose 22 on the outer wall of the pipe 21, the limit ring 23 is moved to drive the clamping plate 25 to cooperate and lock with the retaining ring 26. When the device needs to be removed, the clamping plate 25 is pressed away from the retaining ring 26 to move the clamping plate 25 outward to release the lock with the retaining ring 26, making it convenient to remove the hose 22.

[0039] The heating mechanism 6 includes a heating wire 61, a slot 62 and a movable plate 66. The slot 62 is opened at the bottom of the inner cavity of the shell 1, and the heating wire 61 is installed in the slot 62. The movable plate 66 is located at the top of the slot 62 and its end close to the opening of the shell 1 is rotatably connected to the slot 62 through a rotating shaft 65. A spring 64 is connected between the movable plate 66 and the bottom of the slot 62 so that the other end of the movable plate 66 can be ejected from the slot 62. A push switch 63 is provided at the end of the bottom of the slot 62 away from the opening of the shell 1. The push switch 63 is electrically connected to the heating wire 61. When the other end of the movable plate 66 is pressed into the slot 62, the push switch 63 will be pressed and abut against the heating wire 61.

[0040] The water storage mechanism 3 includes a water tank 31, which is slidably installed at the open part of the outer shell 1. A cover 32 is provided on the top of the water tank 31, and a pipe 2 35 is provided on the side of the cover 32 close to the pipe mechanism 2. When the water tank 31 is moved into the outer shell 1, the pipe 2 35 will dock with the pipe mechanism 2, and the bottom of the water tank 31 will press the movable plate 66 into the slot 62.

[0041] During specific use, the water tank 31 filled with water is moved into the interior of the shell 1, so that the pipe 35 is connected to the pipe mechanism 2. During the movement of the water tank 31, the movable plate 66 is pushed into the slot 62, thereby triggering the press switch 63, so that the heating wire 61 starts to heat, and the movable plate 66 is heated by the heating wire 61 to transfer the heat to the water storage mechanism 3. After the water in the water tank 31 is used up, the water tank 31 is pulled out, and then the movable plate 66 is ejected from the slot 62 under the action of the spring 64, and the press switch 63 can be separated to turn off the heating of the heating wire 61. By automatically cutting off the power when the water storage mechanism 3 is taken out of the shell 1 and stopping the heating, it is avoided that the personnel forget to cut off the power during operation, causing the entire device to be heated all the time, thereby wasting electricity.

[0042] Preferably, the bottom of the water tank 31 is made of heat-conducting metal material, which can better transfer heat to the water to be heated.

[0043] Furthermore, one side of the top of the water tank 31 is rotatably connected to the lid 32 via a hinge 34, and a lock 33 is provided on the other side of the top of the water tank 31 to facilitate opening the lid 32. The lock 33 can be a conventional technical product sold on the market to detachably connect the water tank 31 and the lid 32.

[0044] Preferably, a limiting assembly 5 is also included, which includes a limiting slide rail 51 and a slide groove 52. The slide groove 52 is opened on the inner wall of the shell 1. The limiting slide rail 51 is installed on the outer side of the water tank 31 and is slidably connected to the slide groove 52. The water tank 31 is limited by the slide groove 52 to avoid position displacement.

[0045] In one embodiment, a liquid level monitoring mechanism 4 is also included, which includes a liquid level display column 41, a liquid level sensor 44, a buzzer 47 and an energizing component. The liquid level display column 41 is installed on the outside of the water tank 31 through a fixing column 48 and is connected to the bottom of the water tank 31 through a pipe 43. The bottom of the liquid level display column 41 is flush with the bottom of the inner cavity of the water tank 31. A scale 42 is provided on the outside of the liquid level display column 41. The liquid level sensor 44 is installed on the bottom of the inner cavity of the water tank 31. The buzzer 47 is installed on the outside of the water tank 31 and is electrically connected to the liquid level sensor 44. The energizing component is used to energize the liquid level sensor 44 and the buzzer 47.

[0046] Furthermore, the power supply component includes a plug 45 and a socket 46. The plug 45 is installed on the side of the water tank 31 close to the pipeline mechanism 2 and is electrically connected to the liquid level sensor 44 and the buzzer 47 respectively. A power supply is provided on the side of the inner cavity of the shell 1 away from its opening, and the socket 46 is provided on the side of the power supply close to the water tank 31. When the water tank 31 is moved into the shell 1, the plug 45 will dock with the socket 46.

[0047] Move the water tank 31 into the housing 1 and insert the plug 45 into the socket 46. Water flows into the liquid level display column 41 through the pipe 3 43. The liquid level in the device can be observed through the scale 42 on the liquid level display column 41. When the liquid level is lower than the liquid level sensor 44, the circuit is turned on and the buzzer 47 makes a sound to remind the staff to add water. By reminding the staff of the liquid level in the device, it is avoided that the water in the device is consumed due to negligence at work, which may damage the patient's respiratory tract.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
