[0062] The present application provides a top water-adding type humidifier, in order to make the purpose, technical scheme and effect of the present application more clear and explicit, the present application is further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0063] In the description of the present application, it should be understood that the terms "top", "bottom", "left", "right" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, and a particular orientation configuration and operation, therefore, it cannot be understood as a limitation on the present application. In addition, "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more features. In the description of the present application, unless otherwise specified, the meaning of "multiple" is two or more.

[0064] Please refer to Figures 1-4As shown, the application provides a top water adding humidifier, which comprises a base 1, a water tank 2 detachably arranged on the base 1, a mist outlet cover 3 arranged on the water tank 2, an atomizing sheet 4 arranged at the bottom of the water tank 2, and an atomizing circuit board 5; the base 1 is provided with a containing cavity 101; the atomizing circuit board 5 is provided with a power supply circuit arranged in the containing cavity 101 and electrically connected with the atomizing sheet 4 for controlling high-frequency oscillation of the atomizing sheet 4.

[0065] Further, the top water adding humidifier further comprises a protective box 6, a male connector 7, a connector female seat 8 and a first PCB board 9; the protective box 6 is detachably arranged at the bottom of the water tank 2; the male connector 7 is fixedly arranged at the upper part of the base 1 and electrically connected with the atomizing circuit board 5; the connector female seat 8 is embedded at the bottom of the protective box 6 and used for connecting the male connector 7, and the connector female seat 8 is provided with a downwardly open plug-in interface 81; the first PCB board 9 is arranged in the protective box 6 and used for mounting the connector female seat 8, and the first PCB board 9 is electrically connected with the atomizing sheet 4.

[0066] The application can make the atomizing sheet 4 and the atomizing circuit board 5 conductive by connecting the male connector 7 with the connector female seat 8 when the water tank 2 is placed on the base 1, so that the top water adding humidifier can work normally, and the atomizing sheet 4 and the atomizing circuit board 5 do not need to be always connected, thus, when the user needs to clean the water tank 2, the water tank 2 can be completely separated from the base 1, so as to facilitate the user to clean the water tank 2, and the situation that the cleaning water enters the base 1 and damages the electrical elements in the base 1 does not occur.

[0067] In addition, the protective box 6 can protect the electrical elements in the protective box 6 when the user cleans the water tank 2, so that the electrical elements in the protective box 6 are not in contact with water, and the top water adding humidifier is not easy to be damaged.

[0068] As shown in the drawings, Figure 14 and Figure 15As shown, in an embodiment, the top water adding humidifier further comprises a float liquid level switch, specifically, the float liquid level switch comprises a guide cylinder 10, a magnetic float 11, a limiting piece 12 and a dry reed 13. Wherein, the guide cylinder 10 is vertically arranged at the bottom of the water tank 2; the magnetic float 11 is internally provided with a magnet, and the magnetic float 11 is movably sleeved on the guide cylinder 10 and can float up and down with the water level fluctuation in the water tank 2; the dry reed 13 is arranged in the guide cylinder 10, and the lower end of the dry reed 13 is located in the protection box 6 and is electrically connected with the first PCB 9 and the atomizing sheet 4 respectively.

[0069] When the water in the water tank 2 is used up, the magnetic float 11 contacts the bottom of the water tank 2, at this time, the dry reed 13 is in an open state, even if the water tank 2 is placed on the base 1, the atomizing sheet 4 cannot be conductive with the atomizing circuit board 5, so that the dry burning state of the top water adding humidifier can be prevented; after adding water into the water tank 2, the magnetic float 11 can float upwards, at this time, the dry reed 13 is in a closed state under the action of the magnetic force, so that the atomizing sheet 4 is conductive with the atomizing circuit board 5, and the top water adding humidifier can work normally.

[0070] Further, the limiting piece 12 is arranged at the top of the guide cylinder 10, which is used for limiting the magnetic float 11, so that the magnetic float 11 can be ensured not to be separated from the guide cylinder 10. When there is water in the water tank 2, the magnetic float 11 can always act on the dry reed 13, so that when there is water in the water tank 2, the top water adding humidifier cannot normally atomize.

[0071] As shown in the drawings, Figure 11 In an embodiment, the water tank 2 is a light-transmitting water tank comprising polypropylene material, and the top water adding humidifier further comprises:

[0072] An air outlet pipe 14, which is vertically arranged in the water tank 2;

[0073] A reinforcing rod 15, which is vertically arranged at the air outlet of the air outlet pipe 14.

[0074] By arranging the reinforcing rod 15 at the air outlet of the air outlet pipe 14, after the water tank 2 is demolded, the air outlet of the air outlet pipe 14 will not be deformed due to the polypropylene material not being cooled and shaped, which is beneficial to improve the qualified rate of the water tank 2.

[0075] As shown in the drawings, Figure 6 and Figure 7As shown in the figure, in an embodiment, the top water feeding humidifier further comprises a heat dissipation fin group 16 arranged at the bottom of the atomization circuit board 5, a triode 17 arranged on the atomization circuit board 5 and attached to the heat dissipation fin group 16, and a fan 18 arranged in the accommodating cavity 101. The suction port of the fan 18 faces the heat dissipation assembly, and the outlet of the fan 18 is located below the air outlet pipe 14 and is used to suck the heat on the heat dissipation assembly into the air outlet pipe 14. By facing the heat dissipation assembly with the suction port of the fan 18, when the top water feeding humidifier works, the fan 18 sucks the heat on the heat dissipation assembly and brings the heat into the water tank 2 through the air outlet pipe 14, so that the water in the water tank 2 is more easily atomized, thereby not only effectively cooling the triode 17, but also improving the mist output of the top water feeding humidifier. The fan 18 only needs to maintain the air volume required for mist output, without the need to set multiple suction ports and increase the air volume of the fan 18, so that the energy consumption of the top water feeding humidifier will not increase.

[0076] As shown in the figure, Figure 3 In an embodiment, the top water feeding humidifier further comprises a second PCB board 19 and an LED lamp 20. The second PCB board 19 is arranged in the protective box 6, and the second PCB board 19 is electrically connected with the first PCB board 9, so that the second PCB board 19 can also be powered when the male connector 7 is connected with the female connector 8; the LED lamp 20 is arranged on the second PCB board 19, so that the LED lamp 20 can emit light of different colors when the top water feeding humidifier works. Since the water tank 2 is a light-transmitting water tank, when the LED lamp 20 emits light, the water tank 2 can be lighted and show different colors, so that the top water feeding humidifier has more ornamental value during use.

[0077] As shown in the figure, Figure 8 In an embodiment, the top water feeding humidifier further comprises a key 21 and a third PCB board 22. The key 21 is arranged on the side wall of the base 1; the third PCB board 22 is connected with the key 21, and the third PCB board 22 is electrically connected with the atomization circuit board 5, so that the third PCB board 22 can also be powered when the atomization circuit board 5 is powered.

[0078] By arranging the key 21 and the third PCB board 22, the microcontroller on the atomization circuit board 5 can receive different adjustment signals, for example, the adjustment signal can be an adjustment signal of the oscillation frequency of the atomization sheet 4, so that the user can adjust the oscillation frequency of the atomization sheet 4 by pressing or touching the key 21, thereby adjusting the mist output of the top water feeding humidifier.

[0079] In addition, since the button 21 for regulating different functions of the humidifier is not arranged on the atomization circuit board 5, the area of the atomization circuit board 5 can be reduced, and the upper water filling type humidifier does not need to have a large volume.

[0080] In an embodiment, in order to control the LED lamp 20 to emit different light by pressing or touching the button 21, the third PCB board 22 is also electrically connected with the male connector 7, so that when the third PCB board 22 receives the instruction of the button 21, the third PCB board 22 can directly transmit the control signal to the second PCB board 19 through the male connector 7 and the female connector 8, so that the microcontroller on the atomization circuit board 5 is not needed to control the LED lamp 20 to emit light, and the control of the LED lamp 20 is more convenient.

[0081] As shown in Figure 5 , in an embodiment, the base 1 comprises a base shell 102 and a bottom plate 103 which is detachably arranged on the base shell 102; the base shell 102 and the bottom plate 103 form the accommodating cavity 101; the upper part of the bottom plate 103 is provided with a recess 1031 for positioning the bottom of the water tank 2, so as to facilitate the user to assemble the water tank 2 to the base 1.

[0082] As shown in Figure 1 and Figure 5 , in an embodiment, the recess 1031 is provided with a cavity 1032 for accommodating the protection box 6, the bottom of the cavity 1032 is provided with a drain hole 1033, and the bottom of the base shell 102 is provided with a water outlet hole 1021; the base 1 further comprises:

[0083] a flow guide cylinder 104 which is vertically and fixedly arranged on the bottom of the bottom plate 103, and the upper part of the flow guide cylinder 104 is arranged around the drain hole 1033.

[0084] Since the user may add too much water into the water tank 2 when filling water, and the water may overflow from the air outlet pipe 14 to the bottom plate 103, the embodiment is provided with the drain hole 1033 at the bottom of the cavity 1032, so that the water overflowing on the bottom plate 103 can flow into the cavity 1032 from the recess 1031, and then flow into the accommodating cavity 101 through the drain hole 1033, and then be discharged from the bottom of the base shell 102; and the arrangement of the flow guide cylinder 104 can avoid the water from splashing onto the atomization circuit board 5.

[0085] As shown in Figure 10 and Figure 16As shown, in an embodiment, the top water feeding humidifier further comprises a floating energy gathering ring 23. The floating energy gathering ring 23 is provided with an energy gathering channel 2331 opposite to the atomizing sheet 4, and the floating energy gathering ring 23 is movably sleeved on the air outlet pipe 14. By movably sleeving the floating energy gathering ring 23 on the air outlet pipe 14, and by using the limiting and guiding effect of the air outlet pipe 14 on the floating energy gathering ring 23, when the floating energy gathering ring 23 floats up and down with the water level, the energy gathering channel 2331 of the floating energy gathering ring 23 can still be opposite to the atomizing sheet 4, and will not be deviated, so that the water column generated by the oscillation of the atomizing sheet 4 can be splashed out of the water surface, and the top water feeding humidifier can normally generate mist.

[0086] As shown in the drawings, Figure 16 In an embodiment, the floating energy gathering ring 23 is provided with a through hole 2341 suitable for the air outlet pipe 14 to pass through, and the floating energy gathering ring 23 comprises a limiting plate 231. The limiting plate 231 is vertically provided with multiple limiting plates, and is distributed around the air outlet pipe 14. One side of the limiting plate 231 is connected with the inner wall of the through hole 2341, and the other side is abutted with the outer wall of the air outlet pipe 14. In this way, by the effect of the multiple limiting plates 231, the floating energy gathering ring 23 cannot move in the horizontal direction, and can only float up and down in the same vertical direction, so as to ensure that the energy gathering channel 2331 of the floating energy gathering ring 23 is always opposite to the atomizing sheet 4, and the top water feeding humidifier can normally generate mist.

[0087] As shown in the drawings, Figure 16 In an embodiment, the floating energy gathering ring 23 comprises a floating plate 232, an energy gathering column 233, a mounting column 234, and a reinforcing rib 235. The floating plate 232 is provided with two parallel floating plates. The energy gathering column 233 is used for opening the energy gathering channel 2331, and is arranged between the two floating plates 232. The mounting column 234 is used for opening the through hole 2341, and is arranged between the two floating plates 232. The reinforcing rib 235 is vertically provided with multiple reinforcing ribs, and is located between the two floating plates 232. In this way, when the atomizing sheet 4 oscillates at a high frequency, the floating energy gathering ring 23 can be prevented from being easily deformed, and can be used for a long time.

[0088] As shown in the drawings, Figure 16 In an embodiment, the reinforcing rib 235 can also be connected with the energy gathering column 233. In this way, the energy gathering column 233 can be further prevented from being deformed, and the energy gathering channel 2331 can still effectively gather energy after a long time, so as to ensure that the water column generated by the oscillation of the atomizing sheet 4 can be splashed out of the water surface, and the top water feeding humidifier can normally generate mist.

[0089] As shown in the drawings, Figure 10 and Figure 12As shown, in one embodiment, the top-fill humidifier further includes a handle 24. The handle 24 is rotatably disposed inside the water tank 2, and a water-filling indicator 241 is provided on the grip portion of the handle 24. By providing the water-filling indicator 241 on the grip portion of the handle 24, when the user adds water to the water tank 2, the handle 24 is parallel to the bottom of the water tank 2 inside the water tank 2. Therefore, when the water level in the water tank 2 overflows the water-filling indicator 241, the user can easily know that the water level has reached the maximum allowable water volume of the water tank 2, thereby ensuring that the distance between the bottom of the energy-concentrating channel 2331 and the atomizing plate 4 is maintained within the normal range, and the floating energy-concentrating ring 23 can effectively concentrate energy.

[0090] In one embodiment, the water addition indicator 241 may be the word MAX.

[0091] like Figure 10 and Figure 13 As shown, in one embodiment, the top-fill humidifier further includes a handle base 25. The handle base 25 is disposed on the inner wall of the water tank 2, and the handle base 25 is provided with a limiting groove 251 for limiting the swing angle of the handle 24, so that the handle 24 can only swing between two directions: parallel to the bottom of the water tank 2 and perpendicular to the bottom of the water tank 2. In this way, through the limiting effect of the limiting groove 251, it can be ensured that the handle 24 is parallel to the bottom of the water tank 2 when the user adds water to the water tank 2, so that the water filling indicator 241 can serve as a reminder to the user.

[0092] like Figure 12 As shown, in one embodiment, the handle 24 is provided with a first protrusion 242 and a second protrusion 243 at both ends. The first protrusion 242 and the second protrusion 243 are perpendicular to each other. The first protrusion 242 and the second protrusion 243 are provided on the cylindrical structure 244 at the end of the handle 24. The handle base 25 is provided with a through hole 2341 suitable for the cylindrical structure 244, the first protrusion 242 and the second protrusion 243 to pass through. Two baffles 252 are horizontally provided in the limiting groove 251. During the swinging process of the handle 24, the first protrusion 242 and the second protrusion 243 can swing with the handle 24. Therefore, by providing baffles 252 on both sides of the cylindrical structure 244 to block the first protrusion 242 and the second protrusion 243, the swing angle of the handle 24 can be limited.

[0093] like Figure 6 and Figure 7As shown in the figure, in an embodiment, the fin group 16 comprises a heat-conducting plate 161 and fins 162. The heat-conducting plate 161 is in contact with the triode 17, and the heat-conducting plate 161 and the fins 162 can be made of aluminum alloy or copper. The fins 162 are equidistantly spaced, and the fins 162 are connected to the heat-conducting plate 161 and located between the heat-conducting plate 161 and the fan 18. In this embodiment, the equidistantly spaced fins 162 are arranged on the heat-conducting plate 161, which can increase the heat dissipation area of the fin group 16. With the cooperation of the fan 18, the triode 17 can be effectively cooled.

[0094] As shown in the figure, Figure 1 in an embodiment, the water outlet hole 1021 is located below the fin group 16. When the fan 18 is working, the air outside the top water filling type humidifier can be sucked into the top water filling type humidifier through the water outlet hole 1021, and then the air flows through the fin group 16, so that the heat on the fin group 16 is effectively sucked and sent to the water tank 2 provided with the air outlet pipe 14 by the fan 18, thereby effectively cooling the triode 17.

[0095] As shown in the figure, Figure 8 in an embodiment, the top water filling type humidifier further comprises a blocking strip 26 arranged in the accommodating cavity 101 and located above the water outlet hole 1021. In this embodiment, the blocking strip 26 is arranged above the water outlet hole 1021, so that the air can be sucked into the top water filling type humidifier without affecting the air, and the user's fingers can be prevented from entering the accommodating cavity 101. Especially when the top water filling type humidifier is not powered off, the user can be prevented from contacting the electrical elements in the accommodating cavity 101, and no safety hazard will occur.

[0096] As shown in the figure, Figure 9 in an embodiment, the mist outlet cover 3 comprises a mist outlet upper cover 31, a mist guide channel 32, a cover body 33, and a mist blocking plate 34. The mist outlet upper cover 31 is detachably arranged on the upper part of the water tank 2. The mist guide channel 32 is detachably arranged on the mist outlet upper cover 31 and used for guiding water mist out of the cover body 33. The cover body 33 is fixed on the mist guide channel 32 by a buckle, and the cover body 33 is provided with a first mist outlet 331 for mist outlet. The mist blocking plate 34 is arranged in the mist guide channel 32, and the mist blocking plate 34 and the mist guide channel 32 form a second mist outlet 35 staggered with the first mist outlet 331, so that the water mist can flow in the mist guide channel 32 in a zigzag manner, thereby preventing large droplets from being directly sprayed out of the first mist outlet 331 and wetting the desktop.

[0097] As shown in the figure, Figure 1As shown, in one embodiment, the base 1 further comprises a surrounding plate 105 arranged on the bottom of the bottom plate 103, which surrounds the fan 18, so that even if the user introduces water into the air outlet pipe 14 during the water adding process and the water enters the fan 18, the water on the fan 18 will not splash onto the atomization circuit board 5 due to the blocking of the surrounding plate 105, thereby not only prolonging the service life of the atomization circuit board 5, but also ensuring the electrical safety.

[0098] In summary, the present application provides an upper water adding type humidifier, which has the following advantages compared with the existing upper water adding type humidifier:

[0099] (1) The present application sets a male connector electrically connected with the atomization circuit board on the base, sets a connector female seat on the bottom of the water tank and a first PCB board electrically connected with the atomization sheet and used for mounting the connector female seat, when the water tank is placed on the base, the atomization sheet and the atomization circuit board are connected by connecting the male connector with the connector female seat, so that the humidifier can work normally, without the atomization sheet and the atomization circuit board always being connected, thus when the user needs to clean the water tank, the water tank can be completely separated from the base, thereby facilitating the user to clean the water tank, and without worrying about the cleaning water entering the base and damaging the electrical elements in the base;

[0100] (2) The present application sets a protection box on the bottom of the water tank, and sets the first PCB board and the atomization sheet in the protection box, so that when the user cleans the water tank, the protection box can protect the electrical elements therein, so that the electrical elements in the protection box will not be in contact with water, further making the upper water adding type humidifier not easy to be damaged;

[0101] (3) The present application sets a floating energy gathering ring movable sleeve on the air outlet pipe, and uses the limiting and guiding effect of the air outlet pipe on the floating energy gathering ring, so that when the floating energy gathering ring floats up and down with the water level, the energy gathering channel of the floating energy gathering ring can still be opposite to the atomization sheet, without deviation, thereby not only ensuring that the water column caused by the oscillation of the atomization sheet can be splashed out of the water surface, but also ensuring that the humidifier can normally generate mist;

[0102] (4) The present application sets the air suction port of the fan towards the heat dissipation assembly, when the humidifier works, the fan sucks the heat on the heat dissipation assembly, and brings the heat into the water tank through the air outlet pipe, so that the water in the water tank is more easily atomized, thereby not only effectively cooling the triode, but also improving the mist output of the humidifier. Compared with the existing humidifier products, the present application only needs the fan to maintain the air output amount meeting the mist output requirement, without setting multiple air suction ports and increasing the air output amount of the fan, so that the energy consumption of the humidifier will not increase.

[0103] It can be understood that, for those ordinary skilled in the art, equivalent replacements or changes can be made according to the technical solutions and the inventive concept of the present application, and all the changes or replacements shall fall within the protection scope of the appended claims of the present application.
