Referring to fig. 8-12, and additionally to other figures, fig. 8 is a schematic structural view of the water tank with the body and the cover separated in one embodiment. Fig. 9 is a schematic structural view of a tank body in an embodiment. FIG. 10 is a cross-sectional view of the water tank in a vertical direction in one embodiment. Fig. 11 is a sectional view of the tank body in a vertical direction in one embodiment. Fig. 12 is a schematic structural view of a 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 reservoir space 212 therein. The mist outlet channel 213 may be surrounded by at least part of the reservoir space 212. The mist outlet passage 213 is integrally formed with the water tank. In addition, the mist outlet passage 213 may be provided on the base 1. Specifically, the liquid storage space 212 may be an annular space, and the middle passage is the mist outlet passage 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 channel 213 is elongated, and the mist generating device 4 includes two ultrasonic atomization devices disposed at two ends of the mist outlet channel 213 along the length direction thereof. Of course, in some embodiments, the liquid storage space 212 and the mist outlet channel 213 may also be arranged side by side, that is, the liquid storage space 212 is arranged on one side of the mist outlet channel 213, and the specific structure is not described in detail here.

With continued reference to fig. 10, the mist outlet channel 213 in the mist flowing direction at least includes a flow guiding section 2131 and a mist collecting section 2132 located downstream of the flow guiding section 2131, in this embodiment, the flow guiding section 2131 is located below the mist collecting section 2132, 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 section 2132. The fog gathering section 2132 is generally arranged above the highest water level line of the water tank 2, the fog gathering section 2132 is arranged in the projection area below the liquid inlet 225, liquid flowing down from the liquid inlet 225 can directly fall onto the outer surface of the fog gathering section 2132, then the liquid is gathered with the liquid in the water tank 2 along the outer surface of the fog gathering section 2132, and no obvious water falling sound is generated in the whole process. In one embodiment, the cross-sectional area of the mist focusing section 2132 decreases gradually in the direction of mist flow. The whole mist collecting section 2132 is in a shape with a narrow top and a wide bottom, at this time, water drops directly flow to the outer surface of the mist collecting section 2132 and then are prevented from flowing downwards until the water drops are converged into the solution, and the impact sound generated by the water drops and the outer surface of the mist collecting section 2132 is extremely small and can be ignored. With continued reference to fig. 10, mist focusing segment 2132 terminates in a spray nozzle 2133, which spray nozzle 2133 is elongated. The spray nozzle 2133 is long, so that the spraying effect can be effectively improved, and the aesthetic feeling of sprayed mist can be improved. In one embodiment, the cross-sectional area of the flow guide section 2131 decreases gradually in the direction of mist flow, and the angle of inclination of the flow guide section 2131 is less than the angle of inclination of the mist focusing section 2132. Along the flow direction of the mist, the cross-sectional area of the mist outlet channel is gradually reduced, on one hand, the mist spraying speed is increased, and on the other hand, the condensed liquid drops can slide along the wall surface. Further, the mist collecting section 2132 contracts faster than the flow guiding section 2131, so that the mist outlet speed can be further increased, and the mist can be sprayed farther or higher. In one embodiment, a top wall 221 is provided directly above the inlet 225, the top wall 221 being inclined to direct droplets collected on the top wall 221 toward the inlet 225. In one embodiment, the mist focusing section 2132 is provided with a grasping configuration. Further, the grabbing structure comprises two handles 217 symmetrically arranged on two sides of the fog gathering section 2132, so that a user can conveniently take the water tank 2 or the base 1.

Referring to fig. 8, 13 and 14, fig. 13 is a schematic structural view of a tank cover according to an embodiment. Fig. 14 is a cross-sectional view of the cover shown in fig. 13 in the transverse direction. The cover 22 of the water 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, which includes a bottom wall 222 and a side wall 223, and which may contain a liquid. When the mist outlet channel 213 is located in the middle of the water tank 2, the first cavity at least partially surrounds the mist outlet channel 213. In one embodiment, the cover 22 further includes an elongated mist outlet 224. The elongated mist outlet 224 communicates with the mist outlet passage 213, and mist is discharged out of the humidifier 100 through the mist outlet 224. By adopting the long strip-shaped mist outlet 224, the mist sprayed by the humidifier 100 is a long mist belt, so that the appearance 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 two liquid inlets 225 are respectively positioned at two opposite sides of the elongated mist outlet 224. When the mist outlet passage 213 is located at one side of the water tank 2, the first cavity is adjacent to the mist outlet passage 213. The cover 22 further includes a liquid inlet 225 communicating between the reservoir space 212 and the first cavity, the liquid inlet 225 being at least partially located 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 flows into the water tank 2 through the liquid inlet 225 on the side wall 223, so that the water is added to the humidifier 100. By opening part of the liquid inlet 225 to the side wall 223, the sundries can be effectively prevented from falling into the water tank 2 through the liquid inlet 225 without arranging a cover. When the cover can be removed or pivotally connected, the user can also access or pivot the cover 22 through the opening of the side wall 223, which is more convenient.

With continued reference to fig. 13 and 14, to further reduce debris such as dust from falling directly into the tank 2, at least a portion of the inlet port 225 is located directly below the top wall 221. I.e. the top wall 221 covers at least most of the liquid inlet 225, further the top wall 221 may cover the liquid inlet 225 entirely. Like this, set up inlet 225 under the roof 221, in the place that particulate matter such as some dusts is more, the dust etc. can directly fall into roof 221 and diapire 222, and only very few dust can get into water tank 2 through inlet 225, avoids most dust and tiny granule to fall into water tank 2, causes the water in the water tank 2 to be polluted or the delivery port of water tank 2 to be blockked up.

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

With continued reference to fig. 13-14, in one embodiment, the cover 22 may further include a mist outlet 224, the mist outlet 224 being in communication with the mist outlet channel 213 (see fig. 10). The side wall 223 is recessed toward the mist outlet 224 to form a portion of the liquid inlet 225. When the mist outlet 224 is a long strip, the liquid inlet 225 is also long, so that the liquid inlet area can be effectively increased without increasing the height of the cover 22. In a further embodiment, a water baffle 226 is provided below the top wall 221 opposite the liquid inlet 225. The water deflector 226 is opposite the inlet 225 in the side wall 223 and has the main function of directing the liquid towards the inside 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 provided on the side wall 223 as well as on the bottom wall 222.

Referring to fig. 3 and 15-19, with additional reference to the remaining figures, fig. 15 is a cross-sectional view of an embodiment of a humidifier taken along a horizontal plane. Fig. 16 is a schematic structural view of an atomization bin according to an embodiment. Fig. 17 is a cross-sectional view of the atomization cartridge of fig. 16 taken along the longitudinal direction. Fig. 18 is a cross-sectional view of the base of the humidifier in a lateral direction in one embodiment. Fig. 19 is a cross-sectional view of a humidifier in a lateral direction in one embodiment. The direction of the arrows in fig. 19 is the mist flow direction. As shown in fig. 3, in order to further increase the mist output and ensure "fineness" of the mist, the air outlet 152 of the air supply passage 151 is disposed obliquely with respect to the mist generating device 4. Since the airflow from the outlet port is diffused, the oblique arrangement here is understood to mean that at least the center line of the outlet port is offset from the region corresponding to the mist generating device, i.e., the airflow from the outlet port 152 is not directed toward the region where the mist generating device 4 is located, but is offset from the region. Specifically, the fan installation cavity includes an air supply passage 151, and an air flow from an air outlet 152 of the air supply passage 151 deviates from a region corresponding to the mist generating device 4 in the vertical direction. The air outlet can be an air outlet hole, and can also be an air outlet position formed by matching the air outlet hole with other structures, for example, the air outlet hole is very large, one part of the air outlet hole faces the fog generating device, the part of the air outlet hole facing the fog generating device is shielded, and only one part of the air outlet hole is left to deviate from the fog generating device. With this arrangement, the airflow can directly blow to the objects around the mist generating device 4 (the inner wall 214 of the water tank 2, i.e. the mist outlet channel), i.e. the airflow blows from the air outlet and then directly enters the mist outlet channel, without passing through a circuitous channel, and then directly blows to the inner wall 214, and then the airflow turns along the inner wall 214, specifically, the airflow at the air outlet 152 flows around at least part of the noise reducing device 51 after flowing out in the tangential direction of the noise reducing device 51. The arrangement that the airflow flows around the mist generating device 4 and simultaneously sends out the mist generated by the mist generating device 4 through the mist outlet channel 213 can ensure that the mist generated by the mist generating device 4 is not directly blown away but is carried by the airflow to be sent out of the humidifier 100, and can also ensure that the blown mist is more fine.

In order to prevent the generation of the falling water noise, referring to fig. 16 and 17, a noise reducing device 51 is disposed above the mist generating device 4, the noise reducing device 51 includes a plurality of first brackets 511 extending in a direction away from the mist generating device 4, the plurality of first brackets 511 are disposed at intervals in a ring shape, the first brackets 511 have opposite ends in a length direction thereof, one end of the first bracket 511 away from the mist generating device 4 is provided with a collecting plate 514, and the other end of the first bracket 511 is mounted on the base 1. The noise reduction device 51 is arranged in a hollow cylindrical structure, the surface of the noise reduction device is in a grid shape, the top surface of the noise reduction device is in a flat plate structure, the noise reduction device 51 is covered above the fog generation device 4, fog generated by the ultrasonic fog generation device 4 directly hits the collecting plate 514 and then flows back to the liquid surface along the brackets 183, and the fog is emitted through gaps among the brackets 183. The plurality of first brackets 511 have a certain inclination angle, that is, the top ends of the first brackets 511 are gathered 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, the plurality of second brackets 512 are disposed at intervals on the outer periphery 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 supports 512 is provided with curb plate 513, the upper end of curb plate 513 and the upper end sealing connection of second support 512, curb plate 513 covers the periphery of locating mist generating device 4, curb plate 513 encloses and establishes into the atomizing chamber, curb plate 513 covers establish with mist generating device 4 periphery, seted up the inlet opening on the curb plate 513, communicate with water tank installation cavity 17, liquid enters into the atomizing intracavity through the inlet opening. When the humidifier 100 is in operation, the liquid in the atomization chamber is atomized into mist, and the mist flows out from the gaps between the second brackets 512 and the gaps between the first brackets 511. The airflow blown by the fan 3 is then ejected from the spray port 2133. The top end of the second bracket 512 is lower than the collecting plate 514. The downward angled airflow is facilitated to rotate around 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, i.e., the top ends of the second brackets 512 are outwardly diffused.

Referring to fig. 18 and others, in one embodiment, the outlet 152 is above the collection plate 514 of the noise reducer 51. Like this can effectually prevent that the droplet that fog generating device 4 produced from splashing to air outlet 152, enter into the fan installation intracavity through air outlet 152, make fan 3 and some components and parts wet, cause the 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 the blown mist is relatively small. In order to increase the mist output, a baffle 521 is disposed outside the air outlet 152, the air guiding device 52 includes a baffle 521 disposed at the air outlet 152, 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. It is understood that the air outlet 152 may be configured to blow air obliquely downward to deviate from the mist generating device, and the air outlet may be configured to deviate from the position of the mist generating device 4 and to take the lowest mist, specifically, the air flow blowing obliquely downward may rotate around the mist generating device 4 after being blocked by the wall surface of the mist outlet channel 213, and simultaneously take a large amount of mist to be sprayed from the spray opening 2133 of the mist outlet channel 213. The shape of the air outlet 152 may be configured to be directed 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 outlet 152 and the noise reducer 51. In one embodiment, the deflector 522 is substantially tangential to the outer periphery of the noise reducer 51 for directing the airflow substantially tangentially to the outer periphery of the noise reducer 51. The air deflector 522 may be directly disposed at the air outlet 152 of the cover 12, and another function of the air deflector 522 is to further prevent small droplets generated by the mist generator 4 from splashing to the air outlet 152.

Referring to fig. 18, in another embodiment, the humidifier 100 further includes a wind guiding device 52 disposed outside the air outlet 152, and the wind guiding device 52 is configured to cooperate with the air outlet 152 to guide the air to flow obliquely downward. The air guide device 52 is provided with an air guide plate 522, and the air guide plate 522 is used for guiding the air flow to move along the tangential direction of the periphery of the noise reduction device 51. That is, the air deflector 522 is used to block the air flow from moving toward the direction of the noise reducer 51, in one embodiment, the air deflector 522 is substantially tangent to the outer circumference of the noise reducer 51, and the air deflector 522 further functions to prevent small droplets generated by the mist generator 4 from splashing to the air outlet 152. The air guiding device 52 includes a baffle 521 disposed at the air outlet 152, wherein the baffle 521 is disposed at the outer side of 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, part of the air flow is blocked by the baffle 521 after being blown out from the air outlet 152, then flows downwards and is merged with other air flows flowing out from the air outlet 152 to form an oblique downward air flow, and the oblique downward air flow deviates from the position of the mist generating device 4, so that the air flow rotates around the mist generating device 4 after being blocked by the wall surface of the mist outlet channel 213, and simultaneously carries a large amount of mist to be sprayed out from the spray opening 2133 of the mist outlet channel 213, and therefore, 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 deflector 52 are integrally formed, hereinafter referred to as the atomization bin 5. The atomizing bin 5 is installed on the base 1, further, the atomizing bin 5 is installed on the cover body 12, the cover body 12 defines an air supply channel 151 and an atomizer mounting hole, the mounting space of the water tank 2 is oval, 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 placed at the two ends of the long axis direction of the mounting space of the water tank 2. The atomization chamber 5 is disposed above the air supply duct, and the mist outlet channel 213 covers the atomization chamber 5, at this time, the mist generated by the mist generator 4 is carried by the airflow generated by the fan 3 and is sprayed to the outside of the humidifier 100 along the mist outlet channel 213.

The invention also provides an upper water adding humidifier 100 which comprises a base 1 and a water tank 2. A mist generating device 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 the body 21 defines a liquid storage space 212 therein.

A mist outlet channel 213 is arranged in the base 1 or the water tank 2, wherein the mist outlet channel 213 at least comprises a flow guide section 2131 and a mist collecting section 2132 located at the downstream of the flow guide 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 drip onto the outer surface of the mist collecting section 2132 and then flow into the liquid storage space 212. The above structure can effectively avoid the water falling sound generated after the liquid is dripped into the water tank 2 from the liquid inlet 225.

While embodiments of the invention have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable in various fields of endeavor to which the invention pertains, and further modifications may readily be made by those skilled in the art, it being understood that the invention is not limited to the details shown and described herein without departing from the general concept defined by the appended claims and their equivalents.
