Therefore, they should not be construed as limitations on this utility model.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] See Figures 1-4 This utility model provides a steam sterilizer with high drying efficiency, including a base 1, a heating inner liner 2 disposed on the base 1 for generating steam, and a steaming cage 3 placed on the base 1 and located above the heating inner liner 2. The steaming cage 3 is connected to the heating inner liner 2, and items to be sterilized (such as baby bottles, nipples, etc.) are placed inside the steaming cage 3. The steam generated by the heating inner liner 2 can enter the steaming cage 3 to sterilize the items at high temperature.

[0037] The base 1 is equipped with a hot air drying assembly 4, which includes a mounting bracket 41 with an internal annular air duct 411, an air supply element 42 connected to the annular air duct 411, and a heating element 43 located at the air outlet of the air supply element 42. The heating inner liner 2 is provided with several air outlet holes 23 connected to the annular air duct 411, and the base 1 is also provided with several air inlets. Thus, under the action of the air supply element 42, external air can enter the base 1 through several air inlets and be heated by the heating element 43 to form hot air. The hot air then enters the steamer 3 through the annular air duct 411 and several air outlet holes 23 to achieve drying.

[0038] Therefore, the steam sterilizer of this utility model, by adding an annular air duct 411, allows hot air to first enter the annular air duct 411 and form a vortex before entering the steamer 3 for drying, thereby ensuring that all areas in the steamer 3 are dried simultaneously, thus effectively shortening the drying time and improving the drying efficiency.

[0039] In this embodiment of the invention, the air supply element 42 is a fan; the heating element 43 is a PTC heating element.

[0040] See Figure 3The mounting bracket 41 is also equipped with an air inlet duct 412, and the air supply element 42 is located at the air inlet of the air inlet duct 412. The air outlet of the air inlet duct 412 is tangentially arranged with the side wall of the annular air duct 411, so that the hot air can move in a spiral along the side wall of the annular air duct 411 to form a spiral upward vortex. In addition, the air outlet of the air inlet duct 412 is also equipped with an air guide grille 413, which is parallel to the tangential line of the side wall of the annular air duct 411, so as to effectively ensure the consistency of the hot air flow direction and avoid turbulence.

[0041] Furthermore, a partition plate 414 is provided in the annular air duct 411 near the air outlet of the air inlet pipe 412, so that the hot air coming out of the air outlet of the air inlet pipe 412 can only enter from one side of the annular air duct 411, thereby maximizing the guarantee that all hot air flows in the same direction and avoiding the situation where hot air cancels each other out due to different flow directions.

[0042] In this embodiment, the mounting bracket 41 is made of high-temperature resistant plastic or metal material to avoid aging, powdering and other problems caused by high-temperature steam.

[0043] See Figure 2 and Figure 4 The heated inner liner 2 includes a cup-shaped inner liner body 21, the top of which is provided with a flange 22, which is formed by multiple bending. A through groove is formed in the middle of the mounting bracket 41, through which the inner liner body 21 passes and is hung on the mounting bracket 41 via the flange 22. An annular air duct 411 is arranged around the outer periphery of the inner liner body 21, and several air outlets 23 are provided on the flange 22.

[0044] Therefore, when hot air enters the annular air duct 411 and forms a spiral upward vortex, it can enter the steamer 3 through several air outlets 23 to achieve high-temperature disinfection of items.

[0045] Furthermore, the base 1 also includes a support frame 5 installed at the bottom of the mounting bracket 41. A heating plate 6 is mounted on the support frame 5. When the inner liner 21 is attached to the mounting bracket 41 via the flange 22, the heating plate 6 abuts against the bottom of the inner liner 21 to transfer heat, thereby heating the water inside the inner liner 21 and turning it into steam. Preferably, the heated inner liner 2 is made of stainless steel.

[0046] In order to further improve the thermal conductivity of the heating inner liner 2, the outer bottom surface of the inner liner body 21 is provided with a sandwich layer 24, and an outer bottom layer 25 is fixed to the outside of the sandwich layer 24; preferably, the sandwich layer 24 is an aluminum plate; the outer bottom layer 25 is made of stainless steel.

[0047] Therefore, when the heating plate 6 comes into contact with the outer bottom layer 25, the heat can be quickly conducted to the inner liner body 21 through the interlayer 24, thereby improving the efficiency of steam generation and thus improving the efficiency of steam sterilization.

[0048] See also Figures 1-4 The steamer 3 is made of stainless steel. The steamer 3 includes a first steamer box 31 placed on a base 1 and located above the heating inner liner 2. The first steamer box 31 has a first sterilization chamber 311 formed within it, and a first vent 312 at its bottom, connecting the heating inner liner 2 and the first sterilization chamber 311. The first steamer box 31 also includes several bottle holders 313 for holding baby bottles.

[0049] Therefore, the steam generated by heating the inner liner 2 can enter the first sterilization chamber 311 through several first vent holes 312 to achieve high-temperature sterilization of the baby bottle.

[0050] Furthermore, the steamer 3 also includes a second steamer box 32 placed on the first steamer box 31. The second steamer box 32 has a second sterilization chamber 321 formed inside it. The bottom of the second steamer box 32 has a second air vent 322 that connects the first sterilization chamber 311 and the second sterilization chamber 321 respectively. In addition, the steamer 3 also includes a steamer lid 33 that covers the top of the second steamer box 32 and seals the second sterilization chamber 321.

[0051] Therefore, the high-temperature steam entering the first sterilization chamber 311 can enter the second sterilization chamber 321 through several second vents 322, thereby sterilizing the nipples, spoons and other items placed in the second sterilization chamber 321 at high temperature.

[0052] Therefore, both the heating inner liner 2 and the steamer 3 are made of stainless steel, which can avoid problems such as aging and powdering of plastic products as they are used for a long time. At the same time, it can also avoid the problem of residual plastic odor, making the product safer and more hygienic.

[0053] In summary, the steam sterilizer with high drying efficiency provided by this utility model has the following beneficial effects:

[0054] (I) The steam sterilizer of this utility model, by adding an annular air duct 411, allows hot air to first enter the annular air duct 411 and form a vortex before entering the steamer 3 for drying, thereby ensuring that all areas in the steamer 3 are dried simultaneously, thus effectively shortening the drying time and improving the drying efficiency.

[0055] (II) The steam sterilizer of this utility model, by setting the air outlet of the air inlet pipe 412 tangentially to the side wall of the annular air duct 411, allows hot air to move in a spiral motion along the side wall of the annular air duct 411 to form a spiral upward vortex; in addition, by setting the air guide grille 413 at the air outlet of the air inlet pipe 412 and arranged parallel to the tangential line of the side wall of the annular air duct 411, the consistency of the hot air flow direction can be effectively guaranteed.
