DETAILED DESCRIPTION

[0035] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application.

[0036] In the description of the present application, it should be explained that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the modules or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, therefore it cannot be understood as a limitation of the present application.

[0037] 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 the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application.

[0038] Referring to Figures 1-7 The present application provides a multi-layer cooling hot mist humidifier, which comprises an inner container shell 3, a heating inner container 1 placed in the inner container shell 3, and an upper cover assembly 2 covering the inner container shell 3 and located at the top of the heating inner container 1. The inner part of the heating inner container 1 is provided with a water storage cavity for storing water. The bottom of the heating inner container 1 is provided with a heating module, which can heat the water in the water storage cavity to generate hot steam. The hot steam can be discharged from the upper cover assembly 2 to realize humidification of the surrounding air.

[0039] Specifically, referring to Figures 3-4The upper cover assembly 2 comprises, from top to bottom, an upper cover 21, a middle cover 22, and a lower cover 23. The lower cover 23 and the middle cover 22 form a first clamping cavity therebetween, and the middle cover 22 and the upper cover 21 form a second clamping cavity therebetween. The middle cover 22 is provided with a gas guide pipe 27 penetrating the middle cover 22 and communicating with the first clamping cavity and the second clamping cavity respectively. The lower cover 23 is provided with a plurality of first steam discharge holes 231 communicating with the first clamping cavity. The upper cover 21 is provided with a plurality of second steam discharge holes 211 communicating with the second clamping cavity.

[0040] Thus, the hot steam generated by the heating inner container 1 can enter the first clamping cavity through the plurality of first steam discharge holes 231, flow in the first clamping cavity, enter the second clamping cavity through the gas guide pipe 27, flow in the second clamping cavity, and finally be discharged through the plurality of second steam discharge holes 211. The flow path of the hot steam is shown by arrows in Figure 5 .

[0041] Preferably, the lower cover 23 and the middle cover 22 are made of stainless steel. The upper cover 21 is further provided with a stainless steel condensing cover 28 corresponding to the gas outlet of the gas guide pipe 27.

[0042] Thus, by providing the first clamping cavity and the second clamping cavity, when the hot steam flows in the first clamping cavity, it can contact the stainless steel lower cover 23 and the stainless steel middle cover 22 to rapidly reduce the temperature. When the steam enters the second clamping cavity through the gas guide pipe 27, the steam is discharged from the small cross-sectional area of the gas guide pipe 27 and contacts the large space, so the temperature of the steam rapidly decreases. When the steam is discharged from the gas guide pipe 27 and sprayed onto the stainless steel condensing cover 28, the temperature of the steam can be further reduced. Finally, when the steam flows in the second clamping cavity and is discharged through the second steam discharge holes 211, the steam has been reduced to a low temperature, so even if a user accidentally contacts the steam, the user will not be scalded, thereby improving the safety of the product in use.

[0043] Referring back to Figures 3-6 , the bottom of the upper cover 21 further extends a ring-shaped stop ring portion 212. The bottom wall of the upper cover 21, the inner side wall of the stop ring portion 212, and the top wall of the middle cover 22 form the second clamping cavity therebetween. The bottom of the stop ring portion 212 is further sleeved with a second sealing ring 252, which abuts against the top wall of the middle cover 22 to achieve sealing. In addition, the upper cover assembly 2 further comprises an air bag 24 which is annularly arranged on the outer circumferential side of the upper cover 21 and connected with the outer edge of the middle cover 22 and the outer edge of the lower cover 23. The bottom wall of the upper cover 21, the outer side wall of the stop ring portion 212, the top wall of the middle cover 22, and the inner side wall of the air bag 24 form a third clamping cavity which surrounds the outer periphery of the second clamping cavity. The air bag 24 is provided with a plurality of air inlet holes 241 and air outlet holes 242 which respectively communicate with the third clamping cavity and the external air.

[0044] Therefore, by arranging the third clamping cavity, external air can enter the third clamping cavity and flow to take away heat, thereby playing a role in cooling, and further improving the cooling effect of the steam.

[0045] In the embodiment, a plurality of air inlet holes 241 are arranged on the left and right sides of the air bag 24, and a plurality of air outlet holes 242 are arranged on the front and rear sides of the air bag 24.

[0046] Referring to Figure 5 Further, a gap is formed between the inner container shell 3 and the heating inner container 1 to form an air inlet cavity, the bottom of the inner container shell 3 is provided with an air inlet hole 31 communicating with the air inlet cavity, and the air inlet cavity is in communication with the air inlet hole 241 of the air bag 24; in addition, grooves 243 are arranged on the front and rear sides of the air bag 24, and a plurality of air outlet holes 242 are arranged in the grooves 243. The grooves 243 can form a gap with the inner container shell 3 to form an air outlet cavity.

[0047] Therefore, external air can enter the air inlet cavity through the air inlet hole 31, then enter the third clamping cavity through the plurality of air inlet holes 241, and finally flow out through the plurality of air outlet holes 242 and the air outlet cavity, thereby taking away heat to achieve further cooling. The cold air flow path is indicated by arrows as shown in Figure 7 .

[0048] Of course, it should be noted that in other embodiments, a fan can also be arranged between the inner container shell 3 and the heating inner container 1 to accelerate the flow speed of the cold air, thereby improving the effect of cooling the steam, which is not limited herein.

[0049] In the embodiment, the upper cover 21 and the air bag 24 are plastic parts, and by reducing the temperature of the steam to a lower temperature, problems such as aging and powdering of the plastic parts caused by long-term contact of hot steam with the plastic parts can be avoided, thereby improving the service life of product parts.

[0050] Referring again to Figures 3-6 It also includes a first sealing ring 251 sleeved on the outer sidewall of the air bag 24, when the upper cover assembly 2 is arranged on the top of the heating inner container 1, the first sealing ring 251 extends into the heating inner container 1 and abuts against the inner sidewall of the heating inner container 1 to achieve sealing. The first sealing ring 251 is a double-layer sealing ring structure, that is, an upper and lower spaced two flanges 2511 are arranged on the outer sidewall of the first sealing ring 251, and the two flanges 2511 abut against the inner sidewall of the heating inner container 1 to achieve sealing.

[0051] Therefore, by arranging two flanges 2511 on the first sealing ring 251, a gas protection layer can be formed after the two flanges 2511 abut against and seal the inner sidewall of the heating inner container 1, thereby ensuring that the temperature of the heating inner container 1 is not easily transmitted to the external space, and further ensuring the heat preservation performance of the heating inner container 1.

[0052] Referring back to Figures 3-6 The middle cover 22 is further provided with a plurality of water inlet holes 221 respectively connecting the first clamping cavity and the second clamping cavity and a one-way valve sealing ring 26 arranged at the water inlet hole 221, wherein the one-way valve sealing ring 26 can move upward and seal the plurality of water inlet holes 221 to prevent the steam in the first clamping cavity from entering the second clamping cavity through the water inlet hole 221 when the steam is discharged; when water needs to be added to the heating inner container 1, water can be added to the upper cover 21, and the water in the upper cover 21 can enter the second clamping cavity through the plurality of second steam discharge holes 211 and push the one-way valve sealing ring 26 to move downward and open the water inlet hole 221, at this time, the water in the second clamping cavity can enter the first clamping cavity through the plurality of water inlet holes 221, and finally be discharged into the heating inner container 1 through the plurality of first steam discharge holes 231.

[0053] Therefore, by arranging the one-way valve sealing ring 26, not only can the steam be prevented from running out through the water inlet hole 221, but also the water can enter the first clamping cavity through the water inlet hole 221 when water is added, achieving two purposes at once.

[0054] It should be noted that the one-way valve sealing ring 26 of the present application can be purchased on the market, and its working principle belongs to the prior art, so it will not be described in the present application.

[0055] In addition, the upper cover assembly 2 further comprises a handle 29 arranged on the upper cover 21, and the user can grasp the handle 29 to cover the upper cover assembly 2 on the top of the heating inner container 1 or take out the upper cover assembly 2.
