Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of humidifiers, in particular to a novel double-layer circulation humidifier. Background Art
[0002] Humidifiers are mainly used for heating and humidifying the gas in a ventilator to increase the humidity and temperature of the gas inhaled by patients, making the patients more comfortable when inhaling the gas. The working principle of the humidifier is to heat the water in the humidifier and then evaporate the water. The evaporated water vapor is mixed with the relatively dry gas input, and the mixed gas is provided to the patients.
[0003] The evaporated water vapor exists in the humidifier. Under the conditions of high humidity and uneven temperature, saturated condensation is likely to occur, resulting in large heat loss and power loss of the humidifier. At the same time, when adding water to the humidifier and moving the ventilator, the water in the water tank is likely to flow back into the machine interior or the pipeline interior, causing damage to the machine. In addition, in the case of large flow, water is likely to accumulate in the ventilator pipeline due to splashing, which brings a bad experience to users. Content of the Utility Model
[0004] Therefore, the utility model provides a novel double-layer circulation humidifier to solve the above problems in the prior art.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] According to the first aspect of the utility model, a novel double-layer circulation humidifier includes:
[0007] An upper cover, which is installed on the outer side of the upper end of the water box lower shell through a hinge shaft, and a double-layer partition is fixedly installed inside the upper cover. An air passage is opened on the left side inside the double-layer partition, and a front top cavity located above the double-layer partition is arranged inside the upper end of the upper cover;
[0008] A connecting pipe, which is arranged in the middle of the double-layer partition and behind the air passage, and a prefabricated passage is penetrated and opened inside the connecting pipe;
[0009] Inside the upper end of the upper cover, and a sandwich structure located inside the upper cover is arranged at the lower end of the double-layer partition;
[0010] A rear top cavity, which is arranged inside the upper end of the upper cover and behind the upper layer of the double-layer partition.
[0011] Further, an air inlet communicated with the air passage is penetrated and opened on the left side inside the upper cover, and the lower end of the air passage is inclined.
[0012] Further, a water storage cavity is arranged inside the water box lower shell, and the water storage cavity is located below the connecting pipe.
[0013] Furthermore, a sealing ring is provided at the connection between the lower shell of the water box and the upper cover, and a prefabricated opening is penetrated and provided on the right side of the lower end of the upper cover.
[0014] Furthermore, an air outlet is penetrated and provided inside the left wall of the upper cover and is located directly behind the air inlet, and the air outlet is arranged corresponding to the sandwich structure.
[0015] Furthermore, the lower end of the connecting pipe is inclined.
[0016] Furthermore, a heating plate is provided at the bottom of the lower shell of the water box and is located below the water storage cavity.
[0017] The utility model has the following advantages:
[0018] 1. Through the air path channel, dry and normal-temperature air enters the upper cover from the air inlet, and through the air path channel, the relatively dry and normal-temperature air is first introduced into the front top cavity, then bypasses to the connecting pipe, and vertically enters the lower shell of the water box through the prefabricated channel and enters the water storage cavity filled with heated warm water, which is convenient for heating the normal-temperature air.
[0019] 2. Through the rear top cavity, the normal-temperature dry air in the rear top cavity is relatively low in temperature. Before the normal-temperature air in the rear top cavity enters the water storage cavity, it can also be preheated by the humid and hot air in the sandwich structure through the double-layer partition. At the same time, due to the isolation of the rear top cavity, the overall heat loss is effectively prevented, and the heat utilization rate is improved.
[0020] 3. Through the design of the upper and lower layers of the double-layer partition, the whole can prevent backflow, avoiding the water in the lower shell of the water box from entering the machine interior or the breathing pipeline. In addition, it can ensure that during the operation of the ventilator, the water splashed by the airflow will not enter the machine interior or the breathing pipeline.

[0027] Embodiment 1
[0028] As Figures 1 to 4 shown, the novel double-layer circulation humidifier in the first aspect embodiment of the present utility model includes: The upper cover 2 is installed on the outer side of the upper end of the lower shell 1 of the water box through a hinge shaft. The upper cover 2 is of an openable structure. An air outlet 11 located directly behind the air inlet 5 is penetrated and opened inside the left wall of the upper cover 2. Before use, the air outlet 11 can be docked and installed with an external breathing pipeline. A sealing ring 3 is provided at the connection between the lower shell 1 of the water box and the upper cover 2. The sealing ring 3 can ensure the sealing effect when the upper cover 2 is closed. And a double-layer partition board 4 is fixedly installed inside the upper cover 2. The double-layer partition board 4 is fixedly installed inside the upper end of the upper cover 2. The air passage structure of the double-layer partition board 4 is integrally arranged front and back. The space inside the upper cover 2 is divided into two vertically distributed layers by the double-layer partition board 4;
[0029] An air inlet 5 communicating with the air passage 6 is formed through the left side inside the upper cover 2, and the lower end of the air passage 6 is inclined. An air passage 6 is formed inside the left side of the double-layer partition 4, which facilitates introducing air into the front top cavity 7 through the air passage 6. A front top cavity 7 is arranged inside the upper end of the upper cover 2 above the double-layer partition 4. A connecting pipe 8 is arranged in the middle of the double-layer partition 4 and behind the air passage 6, and a prefabricated passage 9 is formed through the inside of the connecting pipe 8. A water storage cavity 15 is arranged inside the water box lower shell 1, and the water storage cavity 15 is located below the connecting pipe 8. A heating plate 12 is arranged at the bottom of the water box lower shell 1 below the water storage cavity 15. Before use, water is first injected into the water storage cavity 15 and heated by the heating plate 12. During use, dry and normal-temperature air enters the upper cover 2 from the air inlet 5, and through the air passage 6, the relatively dry and normal-temperature air is first introduced into the front top cavity 7, then bypasses to the connecting pipe 8, vertically enters the water box lower shell 1 through the prefabricated passage 9, and enters the water storage cavity 15 filled with heated warm water. The lower end of the connecting pipe 8 is inclined, which increases the mixing area of the evaporated water vapor;
[0030] A sandwich structure 13 located inside the upper cover 2 is arranged at the lower end of the double-layer partition 4. A prefabricated opening 10 is formed through the right side at the lower end of the upper cover 2, and an air outlet 11 is arranged corresponding to the sandwich structure 13. The air is heated by the relatively hot water body in the water storage cavity 15 and mixed with the evaporated water vapor, then bypasses to the prefabricated opening 10 formed in the double-layer partition 4, and the mixed gas vertically upward and then backward enters the sandwich structure 13 in the middle of the double-layer partition 4, so that the humid and hot mixed air leaves the upper cover 2 through the air outlet 11 and enters the external breathing pipeline;
[0031] A rear top cavity 14 is arranged inside the upper end of the upper cover 2 and behind the double-layer partition 4. The rear top cavity 14 contains normal-temperature dry air with a lower temperature. Before the normal-temperature air in the rear top cavity 14 enters the water storage cavity 15, it can also be preheated by the humid and hot air in the sandwich structure 13 through the double-layer partition 4. At the same time, due to the isolation of the rear top cavity 14, the overall heat loss is effectively prevented, and the heat utilization rate is improved;
[0032] The design of the air passage in the double-layer partition 4 enables the whole to prevent backflow. During the daily handling of the ventilator, when the machine sways or tilts, and the overall tilt angle in any direction does not exceed 90°, the water in the water box lower shell 1 will not enter the machine interior or the breathing pipeline. In addition, it can ensure that during the operation of the ventilator, the water splashed by the airflow will not enter the machine interior or the breathing pipeline either.
