In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.

Fig. 1 and 2 show an exploded view of an assembled humidifier and a longitudinal sectional view of an assembled humidifier, respectively, according to the present invention. The specific structure of the humidifier of the present invention will be described below with reference to fig. 1 and 2. As shown in fig. 1, the humidifier has an inner and outer tube structure, and includes an outer tube 1 and an inner tube 2. The structure and positional relationship of the outer cylinder 1 and the inner cylinder 2 are clearly shown in fig. 2. As shown in fig. 2, the longitudinal section of the outer tub 1 resembles an "H" shape, i.e. a first diaphragm 11 is provided within the outer tub 1 and the outer tub 1 has an outer top rim 121. The inner cylinder 2 is located inside the outer cylinder 1 and has a longitudinal section similar to an "H", i.e. a second diaphragm 21 is provided within the inner cylinder 2 and the inner cylinder 2 has an inner top rim 221. Wherein, form the water tank space 3 of water storage on the second diaphragm 21, be equipped with water tank lower nozzle 26 on the second diaphragm 21, be provided with water level control switch 27 in the water tank lower nozzle 26, the bottom of inner tube 2 is shelved on the first diaphragm 11 of urceolus 1. The humidifier further comprises a mist outlet cover 6, the mist outlet cover 6 is positioned at the top of the humidifier, the mist outlet cover 6 is in sealing connection with the outer top edge 121 of the outer barrel 1, mist is prevented from being scattered from the periphery of the mist outlet cover 6, and the sealing mode can be a mode that sealing rings are arranged on the periphery of the mist outlet cover 6 or sealing rings are arranged on the inner periphery of the top edge 121 of the outer barrel 1. Further, as shown, the outer top rim 121 of the outer cylinder 1 is higher than the inner top rim 221 of the inner cylinder 2, that is, the entirety of the inner cylinder 2 is disposed inside the outer cylinder 1, and the outer cylinder 1 covers the entire outer circumference of the inner cylinder 2. It will be appreciated that the outer diameter of the inner barrel 2 is slightly smaller than the inner diameter of the outer barrel 1 so that the inner barrel 2 can be placed inside the outer barrel 1 while ensuring that the gap between the two is as small as possible.

Therefore, the inner and outer cylinder structures of the humidifier eliminate joints between the upper part and the lower part in the prior art, so that even if the water-supply sealing mechanism fails, water cannot overflow from the joints and flow to the tabletop or the ground, and problems and/or potential safety hazards caused by overflow around the humidifier are avoided. And, because the urceolus 2 has wrapped whole inner tube 2, eliminated the assembly gap of traditional humidifier basin and water tank, solved the big and inhomogeneous problem of this assembly gap. This is because of this structure, the outward appearance of humidifier forms a seamless barrel, and its whole is neater, pleasing to the eye.

Further, the first diaphragm 11 of the outer tub 1 divides the wall of the outer tub 1 into upper and lower parts, namely an upper outer tub wall 12 located above the first diaphragm 11, and a lower outer tub wall 13 located below the first diaphragm 11, the upper outer tub wall 12 covering the entire outer circumference of the inner tub 2, and an outer top edge 121 of the outer tub 1, i.e., a top edge 121 of the upper outer tub wall 12. The lower part of the inner cylinder 1 is provided with a transverse second diaphragm 21, and likewise the second diaphragm 21 divides the wall of the inner cylinder 2 into an upper and a lower part, namely an upper inner cylinder wall 22 located above the second diaphragm 21 and a lower inner cylinder wall 23 located below the second diaphragm 21. I.e. the bottom of the lower inner cylinder wall 23 rests on the first diaphragm 11. Likewise, the inner top rim 221 of the inner barrel 2 is the top rim 221 of the upper inner barrel wall 22.

With further reference to fig. 2, the water tank space 3 on the second diaphragm 21 of the inner cylinder 2 is surrounded by the second diaphragm 21 and the upper inner cylinder wall 22, and the upper end thereof is open, and the water tank space 3 can accommodate all the water required by the humidifier in operation, and a user can add the required water thereto from the open upper portion thereof. The second diaphragm 21 of the inner cylinder 2, the lower inner cylinder wall 23 and the first diaphragm 11 of the outer cylinder 1 enclose a further space 4, namely a sump space 4, the sump space 3 being in communication with the sump space 4 via a sump drain 26, water in the sump space 3 being able to flow into the sump space 4.

It can be seen that there is no seam between the water tank space 3 and the water tank space 4 of the humidifier of the present invention, and therefore, even if the water-discharging sealing mechanism of the water tank space 3 fails, water in the water tank space 4 does not overflow to flow to the table or the floor.

As shown in fig. 1 and 2, the humidifier further includes an atomizing device 5 and a bottom cover 7, and their positional connection relationship with the outer tub 1 and/or the inner tub 2 will be described below in connection with the specific structures of the outer tub 1 and the inner tub 2.

The structure of the outer tube 1 in the humidifier of the present invention will be described in detail with reference to fig. 2 and fig. 3a and 3 b. As shown in the figure, the first diaphragm 11 of the outer cylinder 1 is provided with a mounting hole 16, through which mounting hole 16 the upper part of the atomizing device 5 can pass, while the lower part of the atomizing device 5 is mounted and fixed on the mounting hole 16. The first diaphragm 11 is further provided with two upwardly extending channels, namely a drainage channel 14 and an air outlet channel 15. The drain channel 14 is open at both ends, with a drain inlet 141 at the top and a drain outlet 142 at the bottom. When a large amount of water is poured due to misoperation, the water in the water tank space 3 exceeds the warning water level line, and the excessive water flows downwards from the water drainage channel 14 and flows to the desktop or the ground, so that a user can easily find and timely handle the water so as not to cause accidents. An air outlet 151 is arranged at a position of the air outlet channel 15 close to the top end, the bottom of the air outlet channel 15 is connected with a fan 152, and the fan 152 is arranged below the first diaphragm 11. External air enters the air outlet channel 15 from the fan 152 and is blown out from the air outlet 151 to control the direction of mist. In order to avoid that water flows backward from the air outlet 151 into the interior of the humidifier to damage the internal electric parts, the height of the air outlet 151 is designed to be higher than the highest water level in the water tank space 3. In addition, as shown in the figure, in order to save space, the water drainage channel 14 and the air outlet channel 15 may be integrally formed, but are isolated from each other.

The structure of the inner tube 2 in the humidifier of the present invention will be described in detail with reference to fig. 2 and 4. The second diaphragm 21 of the inner cylinder 2 is provided with an atomization channel 24, the lower end of the atomization channel 24 is connected with the upper part of the atomization device 5, the top end of the atomization channel 24 is provided with a mist outlet 241, and mist formed by the atomization device 5 is discharged from the mist outlet 241 along the atomization channel 24. The discharged mist may be dispersed in a target direction under the control of the wind blown out from the air outlet 151. The second diaphragm 21 is further provided with an upwardly extending cover 25, and the cover 25 has a space for accommodating the drain passage 14 and the air outlet passage 15 therein, and the cover 25 just covers the drain passage 14 and the air outlet passage 15 when the inner cylinder 2 is assembled in the outer cylinder 1. The cover 25 is provided with openings (not shown) corresponding to the drain port 141 and the air outlet 151.

Further, a water level control switch 27, preferably a valve body, is provided for opening or closing the drain port 26, thereby controlling the amount of water entering the sump space 4 from the tank space 3. In addition, as shown in fig. 2, in order to match the operation of the water level control switch 27, a float 17 is provided in the water tank space 4, the float 17 corresponds to the position of the water level control switch 27, and a locking portion (not shown) for restricting the float 17 from floating up and down is provided on the outer periphery thereof. The float 17 cooperates with a water level control switch 27 to control the flow of water from the tank space 3 to the tank space 4. The specific structure and working principle of the water level control switch 27 and the float 17 are all the prior art, and the specific reference is shown in the Chinese patent document CN206504431U. As described above, if the water level control switch 27 and/or the float 17 is/are out of order, the drain port 26 cannot be closed in time because of the inner and outer cylinder structure of the humidifier, nor does the water in the water tank space 4 overflow from the periphery thereof.

Therefore, in order to solve the overflow problem, the humidifier of the present invention is provided with multiple guarantees, firstly, the water level control switch 27 at the water outlet 26 of the water tank space 3 and the float 17 ensure that the water entering the water tank space 4 is proper, secondly, even if the water level control switch 27 and/or the float 17 are out of order, the water in the water tank space 4 cannot overflow, and finally, if too much water is injected by misoperation, the excessive water can flow downwards to the ground or the table surface from the water discharge channel 14 in time, so that users can find and process in time.

Further, the structure of the humidifier is convenient for integrally moving the humidifier, a user can lift the whole humidifier by grasping the upper end of the wall of the outer barrel 1 by hand, the humidifier is convenient to move, and the humidifier can be moved without grasping the stable water tank and the water tank at the same time as in the prior art. Meanwhile, the inner cylinder 1 can be lifted singly, in order to facilitate lifting the inner cylinder 1, a lifting structure (not shown) such as a lifting handle can be arranged at the top of the inner cylinder 1, or the inner cylinder 1 can be lifted by grasping the top end of the atomizing channel 24 or the cover 25 on the inner cylinder 1 without arranging the lifting structure, and the water can be added into the water tank space 3 without moving the whole humidifier, so that the water adding process is simple and convenient.
