Detailed Implementation

[0038] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0039] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] 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.

[0041] See Figure 1-7 This utility model provides a hot mist humidifier with good cooling effect, including a heating inner tank 1 and an upper cover assembly 2 covering the top of the heating inner tank 1. The heating inner tank 1 has a water storage cavity for storing water inside, and a heating module is provided at the bottom of the heating inner tank 1. The heating module can heat the water in the water storage cavity to generate hot mist, and then the hot mist rises and is discharged to the outside through the upper cover assembly 2 to humidify the surrounding air.

[0042] Specifically, the upper cover assembly 2 includes an upper cover 21, a lower cover 22 arranged vertically and horizontally with respect to the upper cover 21, and an airbag 23 surrounding the upper cover 21 and the lower cover 22; wherein the upper cover 21, the lower cover 22 and the airbag 23 form a cavity, the lower cover 22 has a plurality of first steam discharge holes 2221 communicating with the cavity, and the upper cover 21 has a plurality of second steam discharge holes 211 communicating with the cavity.

[0043] Therefore, based on the above structure, when the inner liner 1 is heated to generate hot mist, the hot mist flows upward and flows into the clamping cavity through several first steam discharge holes 2221, and then flows in the clamping cavity and is discharged to the outside through several second steam discharge holes 211.

[0044] To ensure that the temperature of the hot fog does not become too high when it is discharged, this application provides an air supply component 4 for cooling the hot fog. The air supply component 4 is located outside the heating inner liner 1 and is used to generate cold air. The airbag 23 has several first air inlets 231 that connect to the clamping cavity. The cold air generated by the air supply component 4 can enter the clamping cavity through the several first air inlets 231 and come into contact with the hot fog in the clamping cavity to cool the hot fog.

[0045] Therefore, by setting the air supply component 4 on the outside of the heating inner liner 1, the cold air generated by the air supply component 4 can be sent into the clamping cavity and come into contact with the hot mist to cool it down. Then, when the hot mist is discharged through the second steam discharge hole 211, its temperature has been reduced to a low level. At this time, even if the user accidentally comes into contact with the steam, he will not be burned, thereby improving the safety of the product.

[0046] See Figure 4 Specifically, the air supply assembly 4 includes an air supply element 41 and an air supply bracket 42. The air supply bracket 42 has a through groove extending along the height direction to form an air duct. The air inlet of the air duct is connected to the air outlet of the air supply element 41, and the air outlet of the air duct is connected to a plurality of first air inlets 231. Thus, the cold air generated from the air outlet of the air supply element 41 can enter the clamping cavity along the air duct and the plurality of first air inlets 231 and cool the hot fog. Preferably, the air supply element 41 has a volute fan.

[0047] Furthermore, it also includes an inner liner shell 3 disposed outside the heating inner liner 1, the inner liner shell 3 and the heating inner liner 1 enclosing to form an installation cavity, the air supply assembly 4 being disposed within the installation cavity; wherein, the inner liner shell 3 includes a shell 31, a bottom cover 33 disposed at the bottom of the shell 31 and a top cover 32 disposed at the top of the shell 31, the top cover 32 having an air inlet cavity 321 respectively connected to a ventilation duct outlet and a plurality of first air inlets 231; the bottom cover 33 having a plurality of second air inlets 331 respectively connecting to the outside and the installation cavity.

[0048] Therefore, when the air supply element 41 is activated, external air can enter the mounting cavity through several second air inlets 331, then enter from the air inlet end of the air supply element 41 and be discharged from the air outlet end of the air supply element 41. Subsequently, the cold air flows along the air duct and enters the air inlet cavity 321, and finally enters the clamping cavity through several first air inlets 231 to achieve the cooling of the hot fog.

[0049] Preferably, the air supply component 4 is provided in two sets, and the two sets of air supply components 4 are respectively located on both sides of the heating inner liner 1, which not only increases the air intake volume, but also makes the air intake more uniform, thereby further improving the cooling effect on the hot fog.

[0050] See Figure 5 The lower cover 22 is made of stainless steel. Specifically, the lower cover 22 includes a stainless steel cover plate 221 and a stainless steel steam outlet 222. The stainless steel cover plate 221 has an opening in the middle, and the stainless steel steam outlet 222 is located at the opening. The stainless steel steam outlet 222 has the aforementioned first steam discharge hole 2221 on its side wall.

[0051] Preferably, a plurality of first steam exhaust holes 2221 are respectively disposed on the left and right sides of the stainless steel steam nozzle 222. Similarly, a plurality of first air inlets 231 are respectively disposed on the left and right sides of the airbag 23, and the plurality of first steam exhaust holes 2221 and the plurality of first air inlets 231 are arranged opposite to each other. This arrangement allows the hot mist discharged from the first steam exhaust holes 2221 to directly collide with the cold air flowing in from the first air inlets 231, thereby achieving rapid cooling of the hot mist and greatly improving the cooling efficiency.

[0052] More specifically, a number of first steam exhaust holes 2221 are arranged at intervals along the circumference of the stainless steel steam outlet 222 to form a steam exhaust grille, and a number of first air inlets 231 are arranged at intervals along the circumference of the airbag 23 to form an air inlet grille. The length and width of the air inlet grille are greater than the length and width of the steam exhaust grille so that the air inlet area is larger than the steam exhaust area, thereby enabling the hot fog to be fully covered and cooled, preventing some hot fog from not being cooled, and greatly improving the cooling effect.

[0053] In addition, the lower cover 22 is made of stainless steel. When the hot mist flows upward and comes into contact with the stainless steel lower cover 22, the temperature of the hot mist can be rapidly reduced, thus achieving initial cooling of the hot mist. Subsequently, the cooled hot mist can enter the clamping cavity through the first steam exhaust hole 2221 and come into contact with the cold air supplied by the air supply component 4 to achieve secondary cooling. Finally, the hot mist, after two cooling processes, is discharged to the outside through the second steam exhaust hole 211. For details on the flow path of the hot mist and the flow path of the cold air, please refer to [reference needed]. Figure 7 .

[0054] In addition, in this embodiment, both the top cover 21 and the airbag 23 are plastic parts. By reducing the temperature of the hot mist in the clamping cavity to a lower temperature, the problem of plastic aging and powdering caused by prolonged contact of hot mist with the plastic parts can be avoided, thereby improving the service life of the product parts.

[0055] Furthermore, it also includes a first sealing ring 24 fitted onto the outer wall of the airbag 23. When the upper cover assembly 2 is placed on top of the heating inner liner 1, the first sealing ring 24 extends into the heating inner liner 1 and abuts against the inner wall of the heating inner liner 1 to achieve a seal. The first sealing ring 24 has a double-layer sealing ring structure, meaning that the outer wall of the first sealing ring 24 has two convex edges 241 arranged at intervals, both of which abut against the inner wall of the heating inner liner 1 to achieve a seal.

[0056] Therefore, by providing two protruding edges 241 on the first sealing ring 24, a gas protective layer can be formed after the two protruding edges 241 abut against and seal with the inner wall of the heating inner liner 1, thereby ensuring that the temperature of the heating inner liner 1 is not easily transferred to the external space, thus ensuring the heat preservation performance of the heating inner liner 1.

[0057] In addition, the bottom of the upper cover 21 is also provided with a retaining ring 212, and the bottom of the retaining ring 212 is fitted with a second sealing ring 25. The second sealing ring 25 abuts against the top of the airbag 23 to achieve a seal, thereby ensuring the airtightness of the cavity.

[0058] In addition, the top cover assembly 2 also includes a handle 26 provided on the top cover 21. Users can grab the handle 26 to place the top cover assembly 2 on the top of the heating inner liner 1 or to remove the top cover assembly 2 from the top of the heating inner liner 1, which is very convenient.

[0059] In summary, the hot mist humidifier with good cooling effect provided by this utility model has the following beneficial effects:

[0060] (I) The hot mist humidifier of this utility model provides an air supply component 4 outside the heating inner tank 1. The cold air generated by the air supply component 4 can be sent into the clamping cavity and come into contact with the hot mist to cool it down.

At this time, even if the user accidentally comes into contact with the steam, he will not be burned, thereby improving the safety of the product.

[0061] (II) The hot mist humidifier of this utility model, by arranging a plurality of first steam exhaust holes 2221 opposite to a plurality of first air inlets 231, allows the hot mist discharged from the first steam exhaust holes 2221 to directly collide with the cold air flowing in from the first air inlets 231, thereby achieving rapid cooling of the hot mist and improving cooling efficiency. Furthermore, the air intake area formed by the plurality of first air inlets 231 is larger than the steam exhaust area formed by the plurality of first steam exhaust holes 2221, thus enabling complete coverage of the hot mist for cooling, preventing some hot mist from remaining uncooled, and greatly improving the cooling effect.

[0062] (III) The lower cover 22 of this utility model's hot mist humidifier is made of stainless steel. When the hot mist flows upward and comes into contact with the stainless steel lower cover 22, the temperature of the hot mist can be rapidly reduced, thereby achieving initial cooling of the hot mist. In addition, since the upper cover 21 and the air bladder 23 are both plastic parts, by reducing the temperature of the hot mist in the cavity to a lower temperature, problems such as plastic aging and powdering caused by prolonged contact between the hot mist and the plastic parts can be avoided, thereby improving the service life of the product components.
