The water pipe 11 connects the first connecting hole 7 and the second connecting hole 8, and the second connecting hole 8 is provided with a sealing device 12.

[0029] In further detail, the first connecting hole 7 is provided with a first through hole 13 connected to the water pipe 11, the second connecting hole 8 is provided with a second through hole 14 connected to the water pipe 11, the second through hole 14 is provided with a first sealing groove 15 on the side close to the water pipe 11, the sealing device 12 includes a sealing cover 16 and a sealing convex ring 17 provided on the periphery of the sealing cover 16, the sealing convex ring 17 is used to be inserted into the first sealing groove 15, the first sealing groove 15 is provided with a limit block 18 for limiting the sealing convex ring 17 from leaving, the sealing convex ring 17 is provided with a limit slide groove 19 for inserting the limit block 18, the sealing convex ring 17 is provided with a plurality of third through holes 20 on one end close to the sealing cover 16, and the sealing cover 1 6 is used to seal the second through hole 14. At the same time, in order to prevent leakage, a first sealing groove 15 and a sealing convex block are specially provided to increase the sealing performance. At the same time, the movement of the sealing device 12 is limited by providing a limit block 18 and a limit slide groove 19 to prevent the sealing convex ring 17 from completely leaving the first sealing groove 15. When the connecting member 9 is inserted into the first connecting hole 7 and the second connecting hole 8, the sealing cover 16 will be pushed out inward, so that the third through hole 20 is exposed in the water pipe 11. At this time, water can be added or water vapor can leave from here and enter the room. The sealing convex ring 17 can also be replaced by a connecting rod, and the third through hole 20 is no longer needed. The humidification effect will be better, but the sealing performance is reduced.

[0030] To further explain, the connecting piece 9 includes a connecting pipe 21 and a ejector pin 22 arranged in the connecting pipe 21, the ejector pin 22 is provided with a plurality of connecting strips 23 and reinforcing strips 24, the connecting strips 23 are used to connect the connecting pipe 21, the reinforcing strips 24 are used to connect the side wall of the ejector pin 22 and the connecting strips 23, the ejector pin 22 is used to lift the sealing cover 16, the first connecting hole 7 and the second connecting hole 8 are both provided with a second sealing groove 25, the second sealing groove 25 is used for the connecting pipe 21 to be inserted, the length of the ejector pin 22 exceeds the pipe mouth of the connecting pipe 21, the connecting strips 23 and the reinforcing strips 24 are provided to strengthen the ejector pin 22 from bending, and reduce the inability to eject the third through hole 20 due to the bending of the ejector pin 22.

[0031] To elaborate further, a first positioning protrusion 26 is provided on the top surface of the electric heater body 1, a positioning groove 27 is provided on the bottom surface of the electric heater body 1, a first connecting hole 7 is provided at the first positioning protrusion 26, and a second connecting hole 8 is provided in the positioning groove 27. This arrangement is used to facilitate the quick connection of two electric heater bodies 1. The modules of the present application are stacked vertically to increase the heating area, but a maximum of three can be installed at a time. They can be arranged in an arranged manner in the horizontal direction, so there is no need to connect horizontally.

[0032] To elaborate further, a third connecting hole 28 is further provided in the positioning groove 27 and the first positioning protrusion 26. The third connecting hole 28 is used for inserting the connecting member 9. In the present application, there are only two first connecting holes 7 and second connecting holes 8, so the effect of fixing only through the first connecting holes 7 and the second connecting holes 8 is not very good, and there is a possibility of tipping forward. Therefore, a third connecting hole 28 is provided in a place where there are no first connecting holes 7 and the second connecting holes 8, for inserting the connecting member 9 for fixing, thereby increasing the fixing effect. A card block can be added to the connecting member 9 to perform a snap connection to the third connecting hole 28, thereby further increasing the fixing performance.

[0033] To elaborate further, the water tank 10 is arranged at the bottom of the heating device 4, and the water tank 10 is provided with two extension blocks 29. The two extension blocks 29 are arranged on both sides of the heating device 4. The water tank 10 is in direct contact with the heating device 4 through the extension blocks 29. The extension blocks 29 need to be made of materials with good thermal conductivity to facilitate heating of the water tank 10, increase the temperature of the liquid, increase the evaporation effect of the liquid, and play a role in humidification.

[0034] To elaborate further, an air guide plate 30 is provided on the top of the side of the heating device 4 away from the blowing device 3, and a secondary air outlet 31 is provided on the electric heater body 1 near the air guide plate 30. The secondary air outlet 31 is aligned with the first connecting hole 7. This setting is used to guide the wind generated by the blowing device 3 to the top of the first connecting hole 7 to accelerate the evaporation of the liquid inside the water pipe 11.

[0035] To be more specific, the filtering device 2 uses a filter screen, the blowing device 3 uses a fan, and the heating device 4 uses a PCT heating plate, and this arrangement uses the prior art.

[0036] In further detail, the electric heater body 1 is provided with a power cord 32 and a receiving groove 33 for receiving the power cord 32. The power cord 32 is used to obtain an external power source and can also be connected to an adjacent electric heater body 1. The receiving groove 33 is provided for convenient storage.

[0037] In further detail, the electric heater body 1 is also provided with a support base 34, and the support base 34 is provided with a support foot 36 and a second positioning protrusion 35 for inserting into the positioning groove 27. A group of electric heater bodies 1 only requires one support base 34. This setting is used to suspend the electric heater body 1, reduce contact with the ground, and reduce power consumption.
