A mist outlet is provided on the cover body. An atomizing chamber is defined in the pot body. The atomizing chamber is arranged to be connected to the mist outlet. A heating disk is also provided inside the pot body and at the bottom of the heating liner. The humidifier uses the above structure to first heat the heating liner through the heating disk, so that the water in the heating liner boils and then generates steam. The steam is finally discharged from the humidifier through the mist outlet. However, during use of the humidifier with this structure, the steam will be directly ejected from the cover through the mist outlet. Moreover, when the humidifier is hit and turned over or tilted, the hot water in the heating liner will overflow, and the overflow speed is relatively fast, so that the user cannot avoid it in time, which can easily cause serious scalding accidents. Therefore, the applicant provides a new solution that can replace the above-mentioned existing technology through structural improvement and perfection for consumers to choose and use.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] First embodiment:

[0022] As shown in Figures 1 to 3, a heating humidifier includes a pot body 1 with an inner pot 3 inside and a cover 2 movably arranged at the mouth of the inner pot 3. The cover 2 and the inner pot 3 together define a heating chamber A for heating water to boiling, and the cover 2 is provided with a steam outlet 201 connected to the heating chamber A. The inner pot 3 is detachably provided with an inner cover 4 adapted to its mouth, and the inner cover 4 is provided with a plurality of connecting holes 401 connecting the heating chamber A and the steam outlet 201.

[0023] The inner cover 4 of this structure can close the mouth of the inner pot 3, so that the boiling water in the inner pot 3 is isolated from the steam, so that the inner cover 4 has the function of preventing the water in the inner pot from overflowing and reducing the noise generated during boiling. Moreover, when the humidifier turns over or tips over, it can reduce the overflow of hot water and reduce the speed of overflow, thus avoiding the hot water from being directly sprayed out, thereby improving the safety of the humidifier. The structure is simple, and the inner cover 4 of this structure is added to the heating humidifier, and the increase in production cost is limited.

[0024] In this embodiment, the connecting through hole 401 and the steam outlet 201 are staggered. This solution can prevent steam from spraying out directly, thereby improving the safety of the humidifier.

[0025] A supporting ledge 301 is provided on the rim of the inner pot 3. The edge of the inner lid 4 rests on the supporting ledge 301, so that the inner lid 4 can be placed on the mouth of the inner pot 3 in a sealed manner. The inner lid 4 of this structure is independent of the pot body 1 and the surface cover 2. After the surface cover 2 is opened, the inner lid 4 can be removed, which makes it easy to clean the inner lid 4. In addition, the supporting ledge 301 ensures that the inner lid 4 is placed on the mouth of the inner pot 3 and is not easily displaced.

[0026] The edge of the inner cover 4 extends upward with a cover side wall 402, and the cover side wall 402 is provided with an outer flange 405 resting on the support lap 301; the outer flange 405 cooperates with the support lap 301 to play a positioning role; and a concave condensate collecting groove 403 is formed on the inner cover 4, and the condensate collecting groove 403 corresponds to the steam outlet 201; during use, the inner cover 4 will be heated by the steam and have a certain temperature. When condensate is formed on the bottom surface of the surface cover 2 and drips into the condensate collecting groove 403 for collection, the inner cover 4 is used to heat the condensate to a certain extent, and then flows back into the inner pot 3 through the connecting through hole 401, so that the temperature of the refluxed condensate is not too low, thereby reducing the impact on the heating efficiency of the inner pot 3.

[0027] An elastic sealing ring 6 is connected to the bottom of the cover 2, and the elastic sealing ring 6 elastically presses against the edge of the inner pot 3; in this embodiment, the elastic sealing ring 6 mainly presses against the supporting edge 301 and forms a sealing structure, so that when the humidifier is turned over or tilted, hot water can only overflow through the connecting through hole 401, greatly reducing the overflow amount and overflow speed.

[0028] A handle 7 is connected to the middle portion of the inner cover 4, and a number of connecting through holes 401 are evenly distributed along the circumference of the handle 7. When the surface cover 2 is placed on the inner pot 3, the bottom surface of the surface cover 2 is pressed against the top of the handle 7. The handle is fastened to the inner cover 4 by screws, and the handle 7 is preferably made of plastic material, which will not be heated in a high temperature environment, so that the user will not be burned when holding the handle 7 to remove the inner cover 4. During use, since the surface cover 2 is pressed against the handle 7, the inner cover 4 is tightly covered on the mouth of the inner pot 3 and will not be lifted or displaced by the high-pressure steam, while improving the sealing between the inner cover 4 and the inner pot 3.

[0029] The middle portion of the inner cover 4 is provided with a secondary sunken condensation water return groove 404 , in which a plurality of connecting through holes 401 are provided; the condensation water return groove 404 can increase the speed of condensation water return.

[0030] The inner cover 4 and the connecting through hole 401 are made of a metal sheet in one piece; the metal material will not deform and will not release odor and harmful substances during high-temperature heating.

[0031] The pot body 1 includes an outer shell 11 and an inner liner 12 connected to the inside of the outer shell 11. One side of the surface cover 2 is flipped and hinged to the outer shell 11. A heating device 13 is provided at the bottom of the inner cavity of the inner liner 12. The inner pot 3 is detachably arranged in the inner cavity of the inner liner 12 and is placed above the heating device 13; the heating device 13 can be a heating plate, and the inner pot 3 is heated by the heating plate so that the water in the inner pot boils and generates steam.

[0032] Second embodiment:

[0033] The structure and principle of the second embodiment are basically the same as those of the first embodiment. The difference is that, as shown in Figure 4, the connecting hole 401 is coaxially arranged with the steam outlet 201, but a shielding structure 5 is provided above the connecting hole 401, and a horizontal connecting channel 501 is formed between the shielding structure 5 and the connecting hole 401; the shielding structure 5 is preferably integrally formed with the inner cover 4 through sheet metal, and the diameter of the shielding structure 5 is greater than or equal to the diameter of the connecting hole 401, and the circuitous path can also be used to prevent direct steam injection.

[0034] Third embodiment:

[0035] The third embodiment differs from the first embodiment in that, as shown in FIG5 , the inner cover 4 is detachably connected to the bottom of the surface cover 2, and the inner cover 4 is spaced apart from the steam outlet 201 above and below. When the surface cover 2 is placed on the inner pot 3, the inner cover 4 is closed and is placed on the mouth of the inner pot 3. This embodiment mainly connects the inner cover 4 to the surface cover 2. When the surface cover is placed on the inner pot 3, the inner cover 4 is placed on the mouth of the inner pot 3, which makes the operation simpler. In addition, the inner cover 4 can also be removed from the surface cover 2 for easy cleaning.

[0036] In addition, at least a portion of the steam outlet 201 is made of silicone material, which can prevent the plastic part from aging after long-term use.

[0037] The above is a preferred embodiment of the present invention, which shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are within the scope of the present invention as claimed, which is defined by the appended claims and their equivalents.
