SPECIFIC IMPLEMENTATION

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.

[0025] As Figure 1 The utility model discloses a humidification device, including base 1, be connected with temperature knob 2 and switch 3 of setting on base 1, temperature knob 2 is used for controlling humidification device to adjust in the preset temperature range, switch 3 is used for controlling the start-stop of humidification device, be provided with heating bottom plate 4 on base 1, be provided with humidification cavity 5 on heating bottom plate 4, be provided with air inlet 7 and air outlet 8 respectively on humidification cavity 5, the position that air inlet 7 and air outlet 8 are connected with humidification cavity 5 are opened with the hole, be provided with air inlet pipe 9 on the one end of air inlet 7 away from humidification cavity 5, be provided with first heating part 12 on air inlet 7, and the inside diameter of first heating part 12 is same with the outside diameter of air inlet 7.

[0026] Specifically, an air outlet 8 is provided with an air outlet pipe 11 at the end away from the humidification chamber 5, and a second heating part 13 is sleeved on the air outlet 8, and the inner diameter of the second heating part 13 is the same as the outer diameter of the air outlet 8.

[0027] When in use, dry air enters the humidification chamber 5 through the air inlet pipe 9 and the air inlet 7 in sequence. The heating base plate 4 starts to work, raising the water temperature inside the humidification chamber 5. As the water temperature rises, the water gradually evaporates into water vapor. The generated water vapor mixes fully with the delivered dry gas to ensure that each part of the gas is fully humidified and heated.

[0028] More specifically, the surface of the humidification chamber 5 is equipped with a water level gauge for staff to directly observe water level changes, and a float plate 6 is installed inside the humidification chamber 5, such as... Figure 2 As shown, the float 6 is a perforated plate that can float up and down inside the humidification chamber 5. A first pressure sensor 14 is installed inside the humidification chamber 5 near the air inlet 7, and a second pressure sensor 15 is installed inside the humidification chamber 5 near the heating base plate 4. Multiple first pressure sensors 14 and second pressure sensors 15 are provided, and both first pressure sensors 14 and second pressure sensors 15 are connected to an audible and visual alarm.

[0029] It should be noted that there is a gap between the second pressure sensor 15 and the heating base plate 4, so as to ensure that when the second pressure sensor 15 is under pressure and alarms, the humidifier can still perform normal humidification while the operator is operating the ventilator without stopping it, thus avoiding dry burning and affecting the service life of the humidifier.

[0030] In use, the operator adds an appropriate amount of distilled or sterile water to the humidification chamber 5. As the water level gradually rises, the float 6 floats upward until it touches the first pressure sensor 14, transmitting a signal to the audible and visual alarm to prevent water overflow during operation due to excessively high water levels, which could damage the electronic components inside the ventilator. As the water level gradually decreases, the float 6 floats downward until it touches the second pressure sensor 15, transmitting a signal to the audible and visual alarm to prevent poor humidification or dry burning of the heating element due to excessively low water levels. Connecting the first pressure sensor 14 and the second pressure sensor 15 to the audible and visual alarm is a common practice among those skilled in the art, and therefore will not be elaborated upon in this embodiment. In the above process, the float 6, in conjunction with the first pressure sensor 14, the second pressure sensor 15, and the audible and visual alarm, can precisely control the water level inside the humidification chamber 5, ensuring the normal operation of the humidification device.

[0031] To solve the problem of uneven and insufficient mixing of air and water vapor, one end of the air inlet 7 penetrates the humidification cavity 5 and is close to the first pressure sensor 14, when the air flows to the air inlet 7, the air can be uniformly mixed in the water level and water vapor, and at the same time the first heating part 12 heats the air, so as to accelerate the movement speed of air molecules and make the movement more intense, which will greatly increase the probability of mutual collision and diffusion of the air molecules, thereby promoting mixing. In addition, the floating plate 6 is provided as a porous plate, and when the water vapor flows through the floating plate 6, it will be divided into many small streams, and the different small streams and the heated air will be interpenetrated and mixed, thereby improving the uniformity of mixing.

[0032] Further, the temperature sensor 10 is arranged inside the air outlet 8 close to the humidification cavity 5, which can identify the temperature of the passing gas in real time, and when the temperature is greatly different from the comfortable temperature of the human body, the second heating part 13 is prompted to work to compensate the temperature of the gas in the air outlet 8, so as to ensure the comfort of the air inhaled by the patient.

[0033] The utility model discloses still a kind of breathing machine comprising the humidification device, air compressor is arranged in the other end of air inlet pipe 9, and the air outside can be inhaled and compressed, to provide sustained stable airflow for breathing machine, to meet the demand of gas when breathing machine works normally. Air outlet pipe 11 other end is provided with breathing mask, and breathing mask is as the interface of gas delivery, and suitable gas is accurately guided to the nasal cavity and oral cavity of patient, so that patient can inhale these gases.

[0034] In operation, the air compressor is started to send the air outside into the humidifying device, when the air flows through the air inlet 7 after passing through the air inlet pipe 9, the first heating part 12 performs the heating treatment on the air, so as to make the air molecules move more violently into the inside of the humidifying cavity 5. At the same time, the switch 3 of the humidifying device is started, and the temperature knob 2 is adjusted to make the heating bottom plate 4 start heating, and the moisture in the humidifying cavity 5 is evaporated into water vapor under the action of heating, when the water vapor flows through the porous plate floating plate 6, it will be divided into many small air flows, and the different small air flows and the heated air are interpenetrated and mixed with each other, so as to improve the mixing uniformity. Then, the air after heating and humidifying passes through the air outlet 8, and the temperature sensor 10 can identify the temperature of the air in real time, when it is identified that the temperature of the air is greatly different from the comfortable temperature of the human body, the second heating part 13 starts to work to compensate the temperature of the air to be inhaled by the human body, so as to ensure the comfort of the air inhaled by the patient. Finally, the suitable air is sent to the breathing mask through the air outlet pipe 11, and then is accurately guided to the nasal cavity and oral cavity of the patient, so that the patient can inhale the air. It should be noted that when the distilled water or sterile water is added to the humidifying cavity 5 by the worker, if the added moisture is too much, the floating plate 6 will float upward until it touches the first pressure sensor 14, and the signal is transmitted to the sound and light alarm to alarm, so as to prevent the problem that the water level is too high to cause the water to overflow when the humidifying device works, and damage the electronic elements in the breathing machine. When the humidifying device works for a period of time, the water level in the humidifying cavity 5 gradually decreases, and the signal is transmitted to the sound and light alarm to alarm, so as to prevent the problem that the water level is too low to cause poor humidifying effect and dry burning of the heating element.
