[0027] The following will describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0028] As Figures 1 to 7 shown, the present utility model discloses an energy-saving and efficient steam humidifier, which includes a water tank 1. A steam cylinder 2 with an opening at the bottom is provided in the water tank 1. The steam cylinder 2 has a receiving cavity 21 communicating with the bottom opening. A water injection structure 3 capable of slowly introducing the water in the water tank 1 into the receiving cavity 21 is provided between the water tank 1 and the steam cylinder 2. A heating plate 4 capable of heating the water in the receiving cavity 21 is provided below the steam cylinder 2. An exhaust port 22 for discharging water vapor is opened on the steam cylinder 2. The water injection structure 3 includes a sealing ring 31 arranged around the bottom opening of the steam cylinder 2, and a first water injection hole 32 communicating the water tank 1 with the receiving cavity 21 is opened on the sealing ring 31.

[0029] The water tank 1 is provided on the inner liner and can store the water source for humidification. The steam cylinder 2 is provided with a receiving cavity 21 to accommodate the water to be heated. The water injection structure 3 can control the water in the water tank 1 to enter the receiving cavity 21. The bottom of the steam cylinder 2 has an opening, which is convenient for the heating plate 4 below the steam cylinder 2 to heat the water in the receiving cavity 21. The sealing ring 31 is arranged around the steam cylinder 2 to prevent water from directly flowing into the receiving cavity 21. The number and size of the first water injection holes 32 can be adjusted according to actual needs. In the embodiment, the number of the first water injection holes 32 is two and they are arranged at the lower part of the sealing ring 31. Through the first water injection holes 32, the water in the water tank 1 slowly and stably enters the receiving cavity 21. The heating plate 4 heats the water in the receiving cavity 21 to evaporate it into steam, and the steam is discharged through the opening 22, thereby achieving the humidification purpose.

[0030] By providing a water injection structure 3 that can control the slow and steady entry of water into the accommodation chamber 21 of the steam cylinder 2, the heating plate 4 only needs to heat the water in the accommodation chamber 21 to generate steam, reducing unnecessary heating, lowering energy consumption, and improving heating efficiency. By providing a sealing ring 31 arranged around the steam cylinder 2 and a first water injection hole 32 that connects the water tank 1 to the accommodation chamber 21, the heating plate 4 only needs to heat a small amount of water that enters the accommodation chamber 21 through the first water injection hole 32. Only a small amount of water needs to be heated each time, and steam can be generated more quickly. By arranging the steam cylinder 2 inside the water tank 1, while the structure is compact, heat dissipation can be reduced, and the overall energy utilization efficiency can be improved.

[0031] A groove 11 is provided at the bottom of the water tank 1, the steam cylinder 2 is arranged inside the groove 11, at least one sealing flange 33 is provided on the outer wall of the sealing ring 31, the outer end of the sealing flange 33 abuts against the inner wall of the groove 11, a second water injection hole 34 is provided on the sealing flange 33, and the height of the first water injection hole 32 is lower than the height of the sealing flange 33.

[0032] The groove 11 can ensure that the steam cylinder 2 is stably placed inside the water tank 1. The sealing flange 33 can be made of an elastic material, so that the sealing flange 33 can closely fit the inner wall of the groove 11. The outer end of the sealing flange 33 abuts against the inner wall of the groove 11 to ensure that water can only enter the accommodation chamber 21 through a specified path. The height of the first water injection hole 32 is lower than the height of the sealing flange 33 to ensure that water needs to pass through the second water injection hole 34 and the first water injection hole 32 in sequence before entering the accommodation chamber 21. By the cooperation of the second water injection hole 34 and the first water injection hole 32, the speed and amount of water entering the accommodation chamber 21 can be jointly controlled.

[0033] Specifically, the number of the sealing flanges 33 is two, and the two sealing flanges 33 are arranged at intervals in the up and down direction.

[0034] With the two sealing flanges 33 arranged at intervals in the up and down direction, a better water blocking effect can be achieved, restricting the direct entry of water flow into the accommodation chamber 21. Compared with only arranging one sealing flange 33, the two sealing flanges 33 arranged at intervals can play a better water blocking role and enhance the stability of the system.

[0035] In the embodiment, the cross-sectional shape of the sealing flange 33 is an inverted triangle shape, which improves stability while reducing weight.

[0036] The second water injection hole 34 includes an upper water injection hole 341 provided on the sealing flange 33 located above and a lower water injection hole 342 provided on the sealing flange 33 located below. The lower water injection hole 342 is provided below the upper water injection hole 341, which can reduce the flow of water and improve the stability of the humidifier when working with less water volume.

[0037] The second water injection hole 34 is arranged outside the sealing flange 33. The inner wall of the groove 11 and the sealing flange 33 jointly guide the water flow into it, which can reduce the acting force of the water flow on the sealing flange 33 while maintaining the structural integrity of the sealing flange 33.

[0038] In the embodiment, a boss 12 is arranged in the middle of the groove 11. The boss 12 is used to prevent the deformation of the bottom position of the water tank 1.

[0039] A heat insulation layer is arranged on the outer wall of the steam cylinder 2, so as to reduce the heat of the water in the steam cylinder 2 to the water tank and reduce the heat dissipation.

[0040] A heat insulation cover 5 is sleeved outside the steam cylinder 2, and a water injection gap 6 for the water in the water tank 1 to flow into the groove 11 is left between the heat insulation cover 5 and the bottom of the water tank 1.

[0041] Through the setting of the heat insulation cover 5, the heat dissipation of the steam cylinder 2 during the heating process can be effectively reduced, thereby improving the heating efficiency. The water injection gap 6 can ensure that the water can flow smoothly from the water tank 1 into the groove 11 and then into the accommodation cavity 21 of the steam cylinder 2.

[0042] A support flange 51 is arranged around the lower part of the heat insulation cover 5, and a spacing convex point 52 is arranged below the support flange 51.

[0043] In the embodiment, the number of the spacing convex points 52 is three and they are arranged equidistantly around the support flange 51. The distance between the heat insulation cover 5 and the water tank 1 is maintained through the spacing convex points 52 to ensure the smoothness of the water injection gap 6.

[0044] In the embodiment, an installation groove 35 is formed in the inner wall of the sealing ring 31, and an installation flange 24 that can cooperate with the installation groove 35 is arranged at the bottom of the steam cylinder 2. Through the setting of the installation groove 35 and the installation flange 24 that cooperates with the installation groove 35, the stable installation of the sealing ring 31 and the steam cylinder 2 is ensured, and the sealing ring 31 is prevented from shifting due to water flow impact or water level change.

[0045] The diameter of the steam cylinder 2 gradually increases from the exhaust port 22 end to the open end. The exhaust port 22 is arranged at the top of the steam cylinder 2. While ensuring the uniform discharge of steam from the opening 22, the contact area between the bottom of the steam cylinder 2 and the heating plate is large, thereby accelerating the heating speed of the water in the accommodation cavity 21 and enabling the rapid generation of steam to achieve the humidification purpose.

[0046] A steam pipe 23 is arranged at the exhaust port 22 end of the steam cylinder 2, and the steam is guided to be discharged quickly and concentrated through the steam pipe 23. The steam cylinder 2 and the steam pipe 23 are integrally formed, which improves the structural strength between the steam cylinder 2 and the steam pipe 6, reduces the stress concentration caused by reasons such as thermal expansion and contraction, and improves the durability.
