Description

Technical Field

[0001] The utility model relates to the technical field of air humidification, in particular to a mist guide pipe and a steam humidifier. Background Art

[0002] A steam humidifier is a humidifier with a heating function, which can generate hot steam and send it into the air for thermal humidification. Figure 1-Figure 3 ) is mainly composed of a fan, a heating component, a water tank, a mist guide pipe and a steam hood. Under the action of the fan, the hot steam generated by the heating component after heating the water will be sent into the mist guide pipe and dissipated into the air. For this reason, it is necessary to open an air outlet on the mist guide pipe. The air outlet of the mist guide pipe of some existing steam humidifiers is opened at a position close to the air inlet of the mist guide pipe, and an annular flow channel is set in the mist guide pipe to guide the steam. However, the annular flow channel of the mist guide pipe can easily cause the steam to overflow from the gap of the steam humidifier due to the existence of resistance during the flow process, causing steam leakage. After the steam leaks, part of the steam will be condensed in some structures inside the steam humidifier to form condensed water, which will cause a short circuit in the circuit or damage to the circuit board. At this time, in order to ensure the safety of the circuit, higher requirements will be placed on the sealing inside the steam humidifier. Utility Model Content

[0037] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0038] Please refer to Figure 3-Figure 7 A steam humidifier includes a base 1, a mist guide pipe 2, a fan, a heating component 3, a water tank 4 and a steam cover 5; the base 1 has an installation cavity 11 for accommodating the mist guide pipe 2, and the bottom of the mist guide pipe 2 and the inner wall of the installation cavity 11 form a mist guide cavity 12. The mist guide pipe 2 includes an annular guide member 21 and a pipe body 22 for connecting the heating component 3 with the steam cover 5; the pipe body 22 has an air inlet 221; the annular guide member 21 is arranged in the pipe body 22 and forms an annular flow channel 210 with the inner wall of the pipe body 22, and an air outlet 211 is opened on the annular guide member 21; the air outlet 211 is located at a position of the annular guide member 21 away from the air inlet 221; the air inlet 221 is connected with the air outlet 211 through the annular flow channel 210.

[0039] It is understandable that by setting the air outlet 211 at a position far away from the air inlet 221, the airflow flows from the air inlet 221 into the annular flow channel 210, flows along the annular flow channel 210, and enters the interior of the tube body 22 from the air outlet 211. Since the air outlet 211 is located on the annular flow channel 210, the flow resistance of the steam in the annular flow channel 210 is reduced, and the problem of steam leakage is solved from the source.

[0040] In some embodiments, the tube body 22 and the annular guide member 21 form an air inlet cavity 222 for communicating with the steam hood 5, and the air inlet 221 is opened on one side of the air inlet cavity 222. The formation of the air inlet cavity 222 plays a guiding role for the steam.

[0041] In some embodiments, the air outlet end of the mist guide pipe 2 also has a steam outlet connector 23 for connecting to the steam hood 5 .

[0042] In some embodiments, the steam humidifier further includes a heating component 3, a water tank 4 and a steam hood 5; the water tank 4 is connected to the heating component 3; and the mist guide cavity 12 is connected to the heating component 3 and the steam hood 5 respectively.

[0043] In some embodiments, the mist guide pipe 2 is detachably connected to the heating component 3 and the steam hood 5, respectively, to facilitate cleaning of the mist guide pipe 2, the heating component 3 and the steam hood 5, thereby preventing scale adhesion from causing pipe blockage and affecting the service life of the steam humidifier.

[0044] In some embodiments, the air inlet chamber 222 of the mist guide pipe 2 is covered outside the steam outlet pipe of the heating component 3, and the steam outlet joint 23 of the mist guide pipe 2 is sleeved outside the air inlet end of the steam hood 5, which can improve the sealing between the mist guide pipe 2 and the heating component 3 and the steam hood 5, and reduce the probability of steam leakage.

[0045] In some embodiments, the plane where the water outlet 41 of the water tank 4 is located is higher than the plane where the water inlet 31 of the heating component 3 is located. Specifically, the heating component 3 and the water tank 4 are connected through a U-shaped water pipe 6, and the water outlet 41 of the water tank 4 and the water inlet 31 of the heating component 3 are on planes at different heights, so that a pressure difference is formed at both ends of the water pipe 6 to ensure that the water tank 4 can continuously supply water to the heating component 3 and improve the smoothness of water inlet.

[0046] In some embodiments, the air inlet 221 and the air outlet 211 are respectively located on both sides of the radial direction of the annular guide member 21. When the air inlet 221 and the air outlet 211 are in this position, the resistance to steam flow on both sides of the annular flow channel 210 can remain relatively balanced, further reducing the probability of steam leakage.

[0047] In some embodiments, the annular guide member 21 and the tube body 22 are integrally formed to improve sealing performance.

The mist guide pipe 2 comprises an annular flow guide 21 and a pipe body 22 for connecting the heating assembly 3 with the steam cover 5; the pipe body 22 has an air inlet 221; the annular flow guide 21 is arranged in the pipe body 22 and forms an annular flow channel 210 with the inner wall of the pipe body 22, and an air outlet 211 is opened on the annular flow guide 21; the air inlet 221 and the air outlet 211 are respectively located on both sides of the annular flow guide 21 in the radial direction; the air inlet 221 is communicated with the air outlet 211 through the annular flow channel 210. Preferably, the annular flow guide 21 and the tube body 22 are integrally formed.

Specifically, the heating component 3 and the water tank 4 are connected through a U-shaped water pipe 6.

[0052] The working principle of this embodiment is:
