[0004] However, in patent authorization number CN217131396U, since wet film 1 and wet film 2 seal the inner side of the humidifying box, when wet film 1 and wet film 2 are completely soaked, although they can humidify the air, they are not conducive to the flow of air, thereby reducing the air output and being not conducive to heating. Therefore, we propose a humidification structure for heating, ventilation and air conditioning engineering to solve the above problems. Utility Model Content

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] Example

[0036] See also Figure 1-6 A humidifying structure for heating, ventilation and air conditioning engineering includes a heating and ventilation duct 1 and a humidifying box 2 conductively connected to the heating and ventilation duct 1. A wet film 3 is installed on the inner side of the humidifying box 2. A plurality of wet films 3 are arranged at equal intervals on the inner side of the humidifying box 2, and adjacent wet films 3 are staggered up and down. The plurality of wet films 3 divide the inner side of the humidifying box 2 into a continuous S-shaped flow channel.

[0037] The bottom of the humidifying box 2 is provided with strip-shaped through holes 4 corresponding to two adjacent wet films 3;

[0038] A water tank 5 is provided below the strip-shaped through hole 4, the top opening of which is fixedly connected to the edge of the bottom wall of the humidifying box 2. A spray pipe 6 is installed on the inner side of the water tank 5 corresponding to the strip-shaped through hole 4. An atomizing nozzle 7 extending to the inner side of the strip-shaped through hole 4 is installed on the outer wall of the spray pipe 6, and a plurality of atomizing nozzles 7 are equidistantly arranged in the axial position of the spray pipe 6.

[0039] A water pump 8 is mounted on the outside of the water tank 5 through a bracket. A connecting pipe 9 is connected between the water outlet of the water pump 8 and the spray pipe 6, and a water pumping pipe 10 is connected between the water inlet of the water pump 8 and the water tank 5.

[0040] It should be noted that when the humidifying structure of the heating, ventilation and air-conditioning project is in use, an appropriate amount of water is first added to the water tank 5. When the heating, ventilation and air-conditioning are used to transport hot air through the heating and ventilation duct 1, the water pump 8 works and the water in the water tank 5 is transported to the spray pipe 6 through the connecting pipe 9 using the suction pipe 10. Then, the wet film 3 is sprayed through the atomizing nozzle 7 under the action of pressure. After the hot air enters the inner side of the humidifying box 2, the hot air is humidified by impacting the wet film 3, and the excess hot air continues to flow on the inner side of the humidifying box 2 through the continuous S-shaped flow channel separated by the wet film 3. The hot air in the flow process is humidified by the water mist continuously sprayed by the atomizing nozzle 7. Finally, the humidified hot air is transported to the room through the heating and ventilation duct 1, which not only can humidify the hot air well, but also ensures the air output, which is beneficial to heating and heat collection.

[0041] like Figure 1 、 Figure 4 As shown, a liquid level sensor 11 is installed on the bottom wall of the humidifying box 2, and the detection end of the liquid level sensor 11 corresponds to the inner cavity of the water tank 5;

[0042] The side wall of the water tank 5 away from the water pump 8 is connected to a water inlet pipe 12, and a solenoid valve 13 is installed on the water inlet pipe 12;

[0043] The outer wall of the humidifying box 2 is equipped with a control host 14;

[0044] The output end of the liquid level sensor 11 is electrically connected to the input end of the control host 14 , and the output end of the control host 14 is electrically connected to the input end of the solenoid valve 13 ;

[0045] It should be noted that the water inlet pipe 12 is connected to the municipal pipeline through a pipeline, and the pressure is supplied by the municipal pipeline. The maximum and minimum monitoring water levels are set for the liquid level sensor 11 through the control host 14. When the liquid level sensor 11 detects the minimum water level, the signal is transmitted to the control host 14. When the control host 14 sends a signal, the solenoid valve 13 opens, and water is poured into the water tank 5 through the water inlet pipe 12. When the liquid level sensor 11 detects the maximum water level, the solenoid valve 13 is controlled to close, and the water tank 5 can be automatically replenished with water.

[0046] The model of the liquid level sensor 11 can be UB500-18GM75-U-V15, and the model of the control host 14 can be J4125-IT-17CM.

[0047] like Figure 5 As shown, the end of the spray pipe 6 away from the water pump 8 is arranged in a closed structure;

[0048] It should be noted that the pressure in the spray pipe 6 is prevented from leaking out, so that the atomizing nozzle 7 can spray the water in the spray pipe 6 out.

[0049] like Figure 1、 Figure 2 、 Figure 6 As shown, the inner side of the port of the heating and ventilation duct 1 is fixedly connected to a limiting flange 15, and the limiting flange 15 is arranged around a circle. The side of the limiting flange 15 close to the port of the heating and ventilation duct 1 is detachably connected to a filter 16;

[0050] The outer wall of the filter 16 is inlaid with a sealing strip 17 that fits tightly against the inner wall of the heating and ventilation duct 1;

[0051] It should be noted that the filter screen 16 is limited by the limiting flange 15, and the sealing strip 17 is used to fill the gap between the filter screen 16 and the heating and ventilation duct 1, so that dust can be well trapped.

[0052] like Figure 6 As shown, grooves 18 are symmetrically formed on the inner edge of the filter 16;

[0053] It should be noted that, by manually inserting a finger into the groove 18 , it is convenient to disassemble the filter 16 and clean the dust attached to its surface.

[0054] During use: first, add an appropriate amount of water to the water tank 5. When the heating ventilation duct 1 uses HVAC to transport hot air, the water pump 8 works and uses the pumping pipe 10 to transport the water in the water tank 5 to the spray pipe 6 through the connecting pipe 9. Then, under the action of pressure, the wet film 3 is sprayed through the atomizing nozzle 7. After the hot air enters the inner side of the humidifying box 2, the hot air is humidified by impacting the wet film 3, and the excess hot air continues to flow inside the humidifying box 2 through the continuous S-shaped flow channel separated by the wet film 3. The hot air in the flow process is humidified by the water mist continuously sprayed by the atomizing nozzle 7. Finally, the humidified hot air is transported to the room through the heating ventilation duct 1.

[0055] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
