Referring to fig. 8-12, and additionally referring to other drawings, fig. 8 is a schematic structural view of a water tank with a body and a cover separated in an embodiment. Fig. 9 is a schematic structural view of a water tank body according to an embodiment. Fig. 10 is a cross-sectional view of a water tank in a vertical direction in an embodiment. Fig. 11 is a sectional view of the water tank body in the vertical direction according to an embodiment. Fig. 12 is a schematic structural view of a water tank body according to an embodiment. As shown in fig. 8 and 9, the water tank 2 includes a body 21 defining a top opening 218 and a cover 22 provided to the top opening 218. The body 21 defines a liquid storage space 212 therein. The mist outlet duct 213 may be surrounded by at least part of the liquid storage space 212. The mist outlet duct 213 is integrally formed with the water tank. In addition, the mist outlet duct 213 may be provided in the base 1. Specifically, the liquid storage space 212 may be an annular space, and the middle channel is the mist outlet channel 213. Specifically, a liquid storage space 212 is defined between an outer wall 211 and an inner wall 214 of the body 21, a mist outlet channel 213 is formed inside the inner wall 214, and the outer wall 211 and the inner wall 214 are integrally formed. In one embodiment, the mist outlet duct 213 is elongated, and the mist generating device 4 includes two ultrasonic atomizing devices disposed at both ends of the mist outlet duct 213 in the longitudinal direction thereof. Of course, in some embodiments, the liquid storage space 212 and the mist outlet duct 213 may be disposed side by side, that is, the liquid storage space 212 is disposed at one side of the mist outlet duct 213, and the specific structure will not be described herein.

With continued reference to fig. 10, the mist outlet duct 213 includes at least a diversion segment 2131 and a mist collecting segment 2132 located downstream of the diversion segment 2131 in the mist flow direction, and in this embodiment, the diversion segment 2131 is located below the mist collecting segment 2132, and the cover 22 includes a liquid inlet 225 communicating with the liquid storage space 212, and a projection of the liquid inlet 225 in the vertical direction falls on an outer surface of the mist collecting segment 2132. The mist collecting section 2132 is generally disposed above the highest water level line of the water tank 2, and the mist collecting section 2132 is disposed in a projection area below the liquid inlet 225, so that liquid flowing down from the liquid inlet 225 can directly fall onto the outer surface of the mist collecting section 2132, and then is converged with the liquid in the water tank 2 along the outer surface of the mist collecting section 2132, so that no obvious water falling sound can be generated in the whole process. In one embodiment, the cross-sectional area of the mist collecting segment 2132 gradually decreases in the mist flow direction. So that the whole mist collecting segment 2132 is in a shape with a narrow upper part and a wide lower part, at this time, after water drops drop on the outer surface of the mist collecting segment 2132, the water drops directly flow downwards until being converged into solution, and the impact sound generated by the water drops and the outer surface of the mist collecting segment 2132 is extremely small and can be ignored. With continued reference to fig. 10, the mist segment 2132 terminates in a spray opening 2133, the spray opening 2133 being elongated. The spray opening 2133 is long, which can effectively improve the spray effect and increase the aesthetic feeling of the sprayed mist. In one embodiment, the cross-sectional area of the deflector 2131 is gradually reduced in the direction of mist flow, and the angle of inclination of the deflector 2131 is smaller than the angle of inclination of the mist gathering section 2132. Along the flow direction of the mist, the cross-sectional area of the mist outlet channel is gradually reduced, on the one hand, the spraying speed of the mist is increased, and on the other hand, the condensed liquid drops can slide along the wall surface. Further, the shrinkage of the mist collecting segment 2132 is faster than the shrinkage of the flow guiding segment 2131, and such a structure can further improve the mist outlet speed, and further or higher the mist is sprayed. In one embodiment, a top wall 221 is disposed directly above the liquid inlet 225, the top wall 221 being inclined to direct liquid droplets that collect on the top wall 221 toward the liquid inlet 225. In one embodiment, the mist gathering section 2132 is provided with a gripping structure. Further, the grabbing structure comprises two handles 217 symmetrically arranged on two sides of the mist collecting section 2132, so that a user can conveniently extract the water tank 2 or the base 1.

Referring to fig. 8, 13 and 14, fig. 13 is a schematic structural diagram of a water tank cover in an embodiment. Fig. 14 is a cross-sectional view of the cover of fig. 13 in a lateral direction. The cover 22 of the tank 2 is detachably disposed at the top opening 218 or the cover 22 is pivotally connected to the body 21. The cover 22 includes a top wall 221, wherein a portion of the top wall 221 of the cover 22 is recessed downward to form a first cavity, the first cavity including a bottom wall 222 and a side wall 223, the first cavity being capable of containing a liquid. When the mist outlet duct 213 is located in the middle of the water tank 2, the first cavity at least partly encloses the mist outlet duct 213. In one embodiment, the cover 22 also includes an elongated mist outlet 224. The elongated mist outlet 224 communicates with the mist outlet duct 213, and mist is discharged out of the humidifier 100 through the mist outlet 224. The long-shaped mist outlet 224 is adopted, so that mist sprayed by the humidifier 100 is a long mist zone, and the humidifier is more attractive. When the first cavity is an annular first cavity, the elongated mist outlet 224 is configured to be surrounded by the first cavity. The liquid inlets 225 are two, and are respectively positioned at two opposite sides of the long-strip-shaped mist outlet 224. When the mist outlet duct 213 is located at one side of the water tank 2, the first cavity is adjacent to the mist outlet duct 213. The cover 22 further includes a fluid inlet 225 communicating with the fluid storage space 212 and the first cavity, the fluid inlet 225 being at least partially disposed on the sidewall 223. When the liquid inlet 225 is located on the side wall 223, a user can directly inject water into the first cavity in the using process, and the liquid can flow into the water tank 2 through the liquid inlet 225 on the side wall 223, so that the water adding of the humidifier 100 is completed. By opening part of the liquid inlet 225 to the side wall 223, sundries can be effectively reduced from falling into the water tank 2 through the liquid inlet 225 without providing a cover. When the cover is removable or pivotally connected, the user can also take or pivot the cover 22 through the opening of the side wall 223, which is more convenient to use.

With continued reference to fig. 13 and 14, in order to further reduce the direct fall of debris such as dust into the interior of the tank 2, at least a portion of the inlet 225 is located directly below the top wall 221. I.e. the top wall 221 covers at least a major part of the inlet 225, further, the top wall 221 may entirely cover the inlet 225. In this way, the liquid inlet 225 is disposed under the top wall 221, where some dust and other particles are relatively more, the dust and other dust can fall directly into the top wall 221 and the bottom wall 222, while only a very small amount of dust can enter the water tank 2 through the liquid inlet 225, so that most dust and fine particles are prevented from falling into the water tank 2, and water in the water tank 2 is polluted or the water outlet of the water tank 2 is blocked.

Referring to fig. 12, in one embodiment, the mist outlet opening 213 is provided with a handle 217 at an end near the cover 22. The two handles 217 are respectively disposed at opposite sides of the mist outlet channel 213, so that a user can conveniently extract the water tank 2 or the whole humidifier 100.

With continued reference to fig. 13-14, in one embodiment, the cover 22 includes a fog outlet 224, and the fog outlet 224 communicates with the fog outlet channel 213 (see fig. 10). The side wall 223 is recessed toward the direction of the mist outlet 224 to form a part of the liquid inlet 225. When the mist outlet 224 is elongated, the liquid inlet 225 is also elongated, so that the liquid inlet area can be effectively increased without increasing the height of the cover 22. In a further embodiment, a water deflector 226 is provided below the top wall 221 opposite the liquid inlet 225. The water deflector 226 is opposite the inlet 225 of the side wall 223 and serves mainly to direct the liquid to the interior of the tank 2.

To further prevent debris from entering the interior of the tank 2, in one embodiment, the inlet 225 is provided with a filter structure (not shown) adjacent the bottom wall 222. The filter structure may be disposed on the side wall 223 or on the bottom wall 222.

Referring to fig. 3 and 15-19, with additional reference to the other figures, fig. 15 is a cross-sectional view of an embodiment of a dehumidifier in a horizontal direction. Fig. 16 is a schematic structural view of an embodiment of an atomization cartridge. Fig. 17 is a cross-sectional view of the atomizing cartridge of fig. 16 in a longitudinal direction. Fig. 18 is a cross-sectional view of a base of a humidifier in a lateral direction according to one embodiment. Fig. 19 is a cross-sectional view of a humidifier in an embodiment in a lateral direction. The arrow direction in fig. 19 is the mist flow direction. As shown in fig. 3, in order to further increase the amount of mist to be discharged and to ensure the "fineness" of the mist, the air outlet 152 of the air supply duct 151 is inclined with respect to the mist generating means 4. Since the airflow blown out from the air outlet is in a diffuse shape, the inclined arrangement is understood to mean that at least the center line of the air outlet is deviated from the area corresponding to the mist generating means, i.e. the airflow blown out from the air outlet 152 is deviated from the area where the mist generating means 4 is located, instead of being opposed to the area. Specifically, the blower mounting chamber includes an air supply passage 151, and the air flow from an air outlet 152 of the air supply passage 151 is deviated from a region corresponding to the mist generating device 4 in the vertical direction. The air outlet can be an air outlet hole or an air outlet position formed after the air outlet hole is matched with other structures, for example, the air outlet hole is large, a part of the air outlet hole is opposite to the mist generating device, a part of the air outlet hole opposite to the mist generating device is shielded, and only a part of the air outlet hole is left to deviate from the mist generating device. With this arrangement, the air flow is blown directly onto the object (the inner wall 214 of the water tank 2, i.e., the mist outlet duct) on the outer periphery of the mist generating means 4, i.e., the air flow is blown out from the air outlet and then directly into the mist outlet duct, without going through a detour duct, and then directly blown to the inner wall 214, and then the air flow is turned along the inner wall 214, specifically, the air flow of the air outlet 152 flows around at least part of the noise reducing means 51 after flowing out in the tangential direction of the noise reducing means 51. The air flow flows around the mist generating device 4 and simultaneously sends the mist generated by the mist generating device 4 out through the mist outlet channel 213, so that the mist generated by the mist generating device 4 is not blown away directly, but is carried by the air flow to be sent out of the humidifier 100, and the blown mist can be ensured to be finer.

In order to prevent the occurrence of water falling noise, referring to fig. 16 and 17, a noise reduction device 51 is provided above the mist generating device 4, the noise reduction device 51 includes a plurality of first brackets 511 extending in a direction away from the mist generating device 4 and a plurality of first brackets 511 being provided in a ring-like interval, the first brackets 511 have opposite ends along a length direction thereof, one end of the first brackets 511 away from the mist generating device 4 is provided with a collecting plate 514, and the other end of the first brackets 511 is mounted on the base 1, wherein a part of water mist generated from the mist generating device 4 is excited, and if the water drops fall back to the liquid surface, the falling noise occurs particularly in quiet. The noise reduction device 51 is arranged in a hollow columnar structure, the surface of the noise reduction device 51 is in a grid shape, the top surface of the noise reduction device is in a flat plate-shaped structure, the noise reduction device 51 is covered above the fog generation device 4, fog generated by the ultrasonic fog generation device 4 can directly strike the collecting plate 514 and then flow back to the surface of liquid along the brackets 183, and the fog can be dispersed out through gaps between the brackets 183. The plurality of first brackets 511 have a certain inclination angle, that is, the top ends of the first brackets 511 gather together to form a truncated cone shape with a narrow top and a wide bottom.

With continued reference to fig. 16 and 17, the noise reducer 51 further includes a plurality of second brackets 512, wherein the plurality of second brackets 512 are disposed at annular intervals on the outer circumferences of the plurality of first brackets 511, and an annular channel is formed between the plurality of first brackets 511 and the plurality of second brackets 512. The periphery of a plurality of second support 512 is provided with curb plate 513, and the upper end of curb plate 513 and the upper end sealing connection of second support 512, curb plate 513 cover the periphery of locating fog generating device 4, and curb plate 513 encloses to establish into the atomizing chamber, and curb plate 513 cover establishes with fog generating device 4 periphery, has seted up the inlet opening on the curb plate 513, communicates with water tank installation cavity 17, and liquid enters into the atomizing intracavity through the inlet opening. When the humidifier 100 is operated, the liquid in the atomizing chamber is atomized into mist, and the mist flows out from the gaps between the plurality of second brackets 512 and the gaps between the plurality of first brackets 511. The air stream blown out by the blower 3 is then ejected from the spray opening 2133 with the coil. The top end of the second bracket 512 is lower than the collecting plate 514. The downward flow of air is conveniently rotated about the first support 511 to carry the mist out of the humidifier 100. The plurality of second brackets 512 also have a certain inclination angle, and the inclination angle of the second brackets 512 is opposite to that of the first brackets 511, that is, the top ends of the second brackets 512 spread outwards.

Referring to fig. 18 and other figures, in one embodiment, the air outlet 152 is above the collection plate 514 of the noise reducer 51. Therefore, the small liquid drops generated by the mist generating device 4 can be effectively prevented from splashing to the air outlet 152, and enter the fan installation cavity through the air outlet 152, so that the fan 3 and some components are affected with damp to cause damage. Since the air outlet 152 is higher than the collecting plate 514, the air flow blown out from the air outlet 152 is relatively upward, and the amount of blown mist is small. In order to increase the amount of mist, a baffle 521 is disposed on the outer side of the air outlet 152, and the air guiding device 52 includes a baffle 521 disposed at the air outlet 152, where the baffle 521 is disposed on the outer side of the air outlet 152 and the lower edge of the baffle 521 is lower than the upper edge of the air outlet 152. It will be appreciated that the air outlet 152 may be configured such that the air flow blown out is inclined downward away from the mist generating device, so that the air flow may deviate from the position of the mist generating device 4 and may carry the mist at the lowermost portion of the roll, specifically, the air flow blown out along the inclined downward rotates around the mist generating device 4 after being blocked by the wall surface of the mist outlet duct 213, and simultaneously carries a large amount of mist to be sprayed out from the mist outlet 2133 of the mist outlet duct 213. The air outlet 152 may be shaped to face obliquely downward, and the specific structure will not be described in detail here.

Referring to fig. 16, an air deflector 522 is provided between the air outlet 152 and the noise reduction device 51. In one embodiment, the air deflector 522 is substantially tangential to the outer perimeter of the noise reducer 51 for directing the airflow in a direction substantially tangential to the outer perimeter of the noise reducer 51. The air deflector 522 may be directly disposed at the air outlet 152 on the cover 12, and another function of the air deflector 522 is to further prevent the droplets generated by the mist generating device 4 from splashing into the air outlet 152.

Referring to fig. 18, in another embodiment, the humidifier 100 further includes an air guiding device 52 disposed outside the air outlet 152, and the air guiding device 52 is configured to cooperate with the air outlet 152 to guide the airflow to flow obliquely downward. The air guide 52 is provided with an air guide plate 522, and the air guide plate 522 is used for guiding the air flow to move in the tangential direction of the outer periphery of the noise reduction device 51. That is, the air deflector 522 is used to block the air flow from moving towards the direction of the noise reducer 51, in one embodiment, the air deflector 522 is substantially tangential to the periphery of the noise reducer 51, and another function of the air deflector 522 is to further prevent the droplets generated by the mist generating device 4 from splashing into the air outlet 152. The air guiding device 52 includes a baffle 521 disposed at the air outlet 152, where the baffle 521 is disposed outside the air outlet 152 and a lower edge of the baffle 521 is lower than an upper edge of the air outlet 152. The baffle 521 and the air outlet 152 have a certain distance, and a part of air flow is blown out from the air outlet 152 and then blocked by the baffle 521, then flows downwards and merges with other air flows flowing out from the air outlet 152 to form an obliquely downward air flow, and the obliquely downward air flow rotates around the mist generating device 4 after being blocked by the wall surface of the mist outlet channel 213 due to the deviation of the position of the mist generating device 4, and simultaneously carries a large amount of mist to be sprayed out from the mist outlet 2133 of the mist outlet channel 213, so that the mist outlet amount can be effectively increased.

With continued reference to fig. 2 and 15-18, in one particular embodiment, the noise reducer 51 and the air guide 52 are integrally formed, hereinafter referred to as the atomizing cartridge 5. The atomizing bin 5 is mounted on the base 1, further, the atomizing bin 5 is mounted on the cover 12, the cover 12 defines an air supply channel 151 and an atomizer mounting hole, the mounting space of the water tank 2 is elliptical, the humidifier 100 comprises two air supply channels, the air outlet directions of the air outlets 152 of the two air supply channels are basically parallel, and the two ultrasonic atomizers are respectively arranged at two ends of the long axis direction of the mounting space of the water tank 2. The atomizing bin 5 is arranged above the air supply duct, and meanwhile, the mist outlet channel 213 is covered on the outer side of the atomizing bin 5, and at this time, mist generated by the mist generating device 4 is carried by air flow generated by the fan 3 and is sprayed to the outside of the humidifier 100 along the mist outlet channel 213.

The application also provides an upper water adding humidifier 100, which comprises a base 1 and a water tank 2. A mist generating means 4 for generating mist is provided in the base 1. The water tank 2 is disposed on the base 1, and the water tank 2 includes a body 21 defining a top opening 218 and a cover 22 disposed on the top opening 218, and a liquid storage space 212 is defined in the body 21.

The base 1 or the water tank 2 is internally provided with a mist outlet channel 213, wherein the mist outlet channel 213 at least comprises a diversion section 2131 and a mist collecting section 2132 positioned at the downstream of the diversion section 2131 along the mist flowing direction, the cover 22 comprises a liquid inlet 225 communicated with the liquid storage space 212, and liquid flowing down from the liquid inlet 225 can drop to the outer surface of the mist collecting section 2132 and then flow into the liquid storage space 212. The structure can effectively avoid the water falling sound generated after the liquid is dripped into the water tank 2 from the liquid inlet 225.
