Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a humidifying device. Background Art

[0002] The water tank of the humidifying device in the prior art includes a tank cover and a tank body. Generally, the tank body and the tank cover are connected by ultrasonic welding or the process of adding rubber in in-mold forming to prevent water leakage.

[0003] Ultrasonic welding refers to using high-frequency vibration waves to transfer to the surfaces of two objects to be under the condition of so that the surfaces of the two objects are mutually and form the between molecular layers. Generally, the water tank is made of plastic. Under the action of ultrasonic vibration, the thermoplastic plastic generates heat due to the friction between surface molecules, so that the tank body and the tank cover are welded together. Although the tank body and the tank cover are welded together and cannot be separated, the water inlet and the water outlet can be arranged on the tank cover. The water inlet can supply humidifying liquid to flow into the water tank, and the water outlet can supply the water pump in the tank body to pump water upwards to realize the humidifying function.

[0004] Adding rubber in in-mold forming, that is, the processing method of secondary forming, refers to re-forming the profile obtained by the primary forming of the polymer material to obtain the final pattern of the product. This technology is applicable to and is carried out under the condition of lower than the polymer flow temperature or melting temperature, and the re-forming of the material is realized through viscoelastic deformation. For example, for some humidifying devices, the tank cover is opened to realize water injection, cleaning and inspection, so the tank cover and the tank body are detachable structures. Rubber is provided between the tank cover and the tank body. Through secondary forming, the rubber is combined with the tank cover. Specifically, the rubber is re-formed through viscoelastic deformation and forms an integral non-detachable structure with the tank cover, thereby improving the sealing performance.

[0005] Since the water tank using ultrasonic welding must be provided with a water inlet and a water outlet, and the tank cover and the tank body using in-mold forming to add rubber are detachable structures, no matter what, the risk of water leakage from the water tank after the humidifying device is toppled cannot be completely avoided. After the water leaks out, it is easy to spread to the charged components in the machine body, resulting in a short circuit of the humidifying device. Utility Model Content

[0050] ​The side wall connects the base 14 and the top shell 13, and includes a front shell 11 and a rear shell 12. The rear shell 12 is detachably connected to the front shell 11, and the water tank 20 can be disassembled and assembled from the humidifying device through the detachable connection.

[0051] In this embodiment, the rear shell 12 is arranged on the back of the shell 10 and is in the shape of a flat plate. The front shell 11 is a structure formed by being arranged on the front and two opposite sides of the shell 10. From the cross-section, the front shell 11 is in the shape of a "匚", and after being connected with the rear shell 12, the cross-section is in the shape of a "口". In other optional embodiments, the front shell 11 and the shell 10 can be opposite to the shapes in this embodiment, for example, the front shell 11 can also be only arranged on the front of the shell 10 and is in the shape of a flat plate, and the rear shell 12 is a structure formed by being arranged on the back and two opposite sides of the shell 10, and from the cross-section, it is in the shape of a "匚", and after being connected with the front shell 11, the cross-section is in the shape of a "口". In other optional embodiments, the cross-sections of the front shell 11 and the rear shell 12 are both in the shape of a "匚", and the cross-section formed after the two are connected is in the shape of a "口". In other optional embodiments, the cross-sections of the front shell 11 and the rear shell 12 are both in the shape of an "L", and the cross-section formed after the two are connected is in the shape of a "口". The front shell 11 and the rear shell 12 can be detachably connected by means of screw connection, snap connection, plug connection, etc.

[0052] In this embodiment, according to the position and shape of the front shell 11, the front shell 11 is divided into a front panel 111 and a side panel 112.

[0055] As Figure 5 , Figure 6 and Figure 12 shown, the water tank 20 is disposed above the base 14. The water tank 20 has a box-shaped structure formed by six surfaces surrounding each other. The water tank 20 includes a water tank cover and a box body. An opening is provided on the box body, and the water tank cover covers the opening of the box body. The water tank cover is located on one of the six surfaces of the water tank 20. The water tank 20 includes a top surface, four side surfaces, and a bottom surface. Considering factors such as gravity and the fluidity of water, the water tank cover is usually disposed on the top surface of the water tank 20. The top surface of the water tank 20 is an opening structure that can cooperate with the water tank cover, and the water tank cover can cover the top surface of the water tank 20.

[0056] The electrical part includes a main control board 31 and a circuit board 32, which are used to control the operation of the humidifying device. The electrical part is disposed close to the top shell 13. The main control board 31 is disposed at a corner below the top shell 13 and beside the air outlet. The circuit board 32 is disposed below the main control board 31.

[0057] As Figures 4 to 13 shown, a water separation part 40 is provided between the electrical part and the water tank 20. The water separation part 40 is disposed inside the outer shell 10. The water separation part 40 includes a water tank accommodating part 41, a circuit board box accommodating part 43, and a main control board waterproof part 42. The water separation part 40 further includes a connecting section that connects the water tank accommodating part 41, the circuit board box accommodating part 43, and the main control board waterproof part 42 into a whole.

[0058] The main control board waterproof part 42, the circuit board box accommodating part 43, and the water tank accommodating part 41 are arranged in a position from top to bottom in the direction of the normal use state of the humidifying device. That is to say, the main control board waterproof part 42 is disposed above the circuit board box accommodating part 43, and the water tank accommodating part 41 is disposed below the circuit board box accommodating part 43. In this embodiment, in order to improve the sealing performance, the main control board waterproof part 42, the circuit board box accommodating part 43, and the water tank accommodating part 41 are integrally formed. In other alternative embodiments, the main control board waterproof part 42, the circuit board box accommodating part 43, and the water tank accommodating part 41 can be separate components and combined by means of snap connection or the like.

[0059] The water tank accommodating part 41 is structured to at least partially surround the water tank 20. In this embodiment, it is formed in a cuboid shape with two openings by connecting four flat plates. One opening faces the bottom of the humidifying device, and the other opening faces the back of the humidifying device. The base 14 covers the opening facing the bottom of the humidifying device to jointly form a hollow structure with the water tank accommodating part 41 that can accommodate the water tank 20. The shape of the hollow structure is consistent with that of the water tank 20. Specifically, the water tank 20 is cuboid, and the hollow structure is a cuboid slightly larger than the water tank 20 so that the hollow structure can accommodate the water tank 20. The other opening facing the back of the humidifying device is used to insert or remove the water tank 20. After the rear shell 12 is installed, it can cover the opening facing the back of the humidifying device to prevent the water tank 20 from slipping out of the opening facing the back of the humidifying device. The water tank accommodating part 41 includes an inner side 411 of the water tank accommodating part and an outer side 412 of the water tank accommodating part. The inner side 411 of the water tank accommodating part faces the side that surrounds the water tank 20. The outer side 412 of the water tank accommodating part is opposite to the inner side 411 of the water tank accommodating part and faces the side of the housing 10.

[0060] As Figure 2 and Figure 7 shown, a water blocking rib 50 is provided between the water blocking part 40 and the housing 10. The water blocking rib 50 includes a blocking rib 51.

[0061] The blocking rib 51 is provided on the housing 10 and is a protrusion protruding and extending from the housing 10 in the direction towards the water blocking part 40. Further, in order to improve the sealing performance between the housing 10 and the water blocking part 40, the blocking rib 51 is fitted to the water tank accommodating part 41. In this embodiment, in the direction of the normal use state, the blocking rib 51 is fitted to the top surface of the outer side 412 of the water tank accommodating part. The blocking rib 51 is in a narrow strip shape, and the width and thickness of the blocking rib 51 are set according to actual requirements. In other embodiments, the blocking rib 51 is fitted to the side surface of the water tank accommodating part 41.

[0062] The position of the retaining rib 51 can also be selected according to the shapes of the front shell 11 and the rear shell 12, combined with the position of the second drainage hole 102 described below. Specifically, the retaining rib 51 can be arranged on other surfaces of the shell 10 without the second drainage hole 102, that is, when the second drainage hole 102 is arranged on the rear shell 12 and on the back of the shell 10, then the retaining rib 51 can be arranged on the front and side of the shell 10, that is, the retaining rib 51 can be arranged on the front shell 11, or on the front shell 11 and the rear shell 12. In this embodiment, since the rear shell 12 is arranged on the back of the shell 10 and is in the shape of a flat plate, the front shell 11 is a structure formed by being arranged on the front and two opposite sides of the shell 10, and the cross section is in the shape of a "匚", then the retaining rib 51 can be arranged on the front shell 11, extending from one end of the front shell 11 connected to the rear shell 12 to the other end of the front shell 11 connected to the rear shell 12, so as to form a surrounding edge. In other optional embodiments, since the front shell 11 is disposed on the front of the outer shell 10 and is in the shape of a flat plate, and the rear shell 12 is a structure formed by being disposed on the back and two opposite sides of the outer shell 10, and the cross section is in the shape of a "匚", then the retaining ribs 51 can be disposed on the front shell 11 and the rear shell 12, and the head and tail of the retaining ribs 51 of the front shell 11 are connected to the retaining ribs 51 of the rear shell 12 to form a surrounding edge. In other optional embodiments, the cross sections of the front shell 11 and the rear shell 12 are both in the shape of a "匚", and the cross sections formed by the two being matched and connected are in the shape of a "口", or the cross sections of the front shell 11 and the rear shell 12 are both in the shape of an "L", and the cross sections formed by the two being matched and connected are in the shape of a "口", then the retaining ribs 51 can be disposed on the front shell 11 and the rear shell 12, and the head and tail of the retaining ribs 51 of the front shell 11 are connected to the retaining ribs 51 of the rear shell 12 to form a surrounding edge.

[0063] like Figure 10 and Figure 11 As shown, the water barrier 50 also includes a protruding rib 52, which is provided on the water barrier 40 and is a protrusion extending from the water barrier 40 toward the outer shell 10, that is, the protruding rib 52 faces the side direction of the outer shell 10. In order to enhance the sealing performance between the water barrier 40 and the outer shell 10, the protruding rib 52 can contact the outer shell 10. According to the shapes of the front shell 11 and the rear shell 12 mentioned above, the protruding rib 52 can contact the front shell 11 and / or the rear shell 12. In this embodiment, the protruding rib 52 contacts the front shell 11.

[0064] like Figure 12 and Figure 13 As shown, the ribs 52 include a first rib 521 and a second rib 522. The first rib 521 extends from the top shell 13 toward the base 14, and is a multi-layer square bent arch structure. Further, the first rib 521 is detachably connected to the fixing rib 113 described below, so that the shell 10 is connected to the water barrier 40. The second rib 522 is provided on the outside of the water tank accommodating portion 41, and is a rib extending from the front side of the shell 10 to the back side.

[0065] likeFigure 2 As shown in the figure, in this embodiment, the front shell 11 further includes a fixing rib 113, which is provided at a position close to the connection between the front shell 11 and the rear shell 12, and is a protrusion extending from the front shell 11 towards the water-proof part 40. Specifically, the fixing rib 113 is provided on the side panel 112 of the front shell 11, and extends in a forked manner from one end where the front shell 11 is connected to the rear shell 12. Moreover, the closer it is to the front direction of the outer shell 10, the thinner the thickness of the fixing rib 113 and the larger the forked angle, gradually tending to be flush with the side panel 112.

[0066] The first rib 521 includes a first connecting plate 5211 and two first side plate bodies 5212 located on both sides of the first connecting plate 5211, and through holes are provided on the first connecting plate 5211. The first connecting plate 5211 and the two first side plate bodies 5212 enclose an accommodating area for the fixing rib 113. The fixing rib 113 includes a second connecting plate 1131 and two second side plate bodies 1132 located on both sides of the second connecting plate 1131, and threaded holes are provided on the second connecting plate 1131. After the water-proof part 40 is assembled with the front shell 11, the fixing rib 113 is located in the accommodating area surrounded by the first rib 521. The first connecting plate 5211 and the second connecting plate 1131 are close to or in contact with each other, the through holes and the threaded holes are aligned, and fasteners are screwed into the through holes and the threaded holes to achieve the detachable connection between the first rib 521 and the fixing rib 113. The fasteners can be screws.

[0067] The number of the first ribs 521 and the fixing ribs 113 is set according to actual needs. In this embodiment, three fixing ribs 113 are provided on the side panel 112 opposite to the circuit board box accommodating part 43, while four fixing ribs 113 are provided on the other side panel 112. Three first ribs 521 are provided on the side of the water-proof part 40 where the circuit board box accommodating part 43 is located, while four first ribs 521 are provided on the other side. The first ribs 521 and the fixing ribs 113 are connected in one-to-one correspondence.

[0068] The front shell 11 and the water-proof part 40 are connected through the first ribs 521 and the fixing ribs 113, which can effectively prevent the outer shell 10 from shaking during use. The multiple first ribs 521 and the multiple fixing ribs 113 are connected in one-to-one correspondence, which is beneficial to ensuring the stability of the outer shell 10, enabling the outer shell 10 to be stably matched with the water-proof part 40, thereby ensuring that the blocking rib 51 is in contact with the water tank accommodating part 41 and improving the sealing performance.

[0069] The outer shell 10 is provided with a drain hole, which is communicated with the water tank accommodating part 41 and is used to drain the liquid leaked from the water tank 20 outside the humidifying device. According to the different positions of the drain hole, the drain hole includes a first drain hole 101 and a second drain hole 102, and the number of the drain holes is set according to actual needs.

The first drain hole 101 is distributed around the base 14 and is close to the position where the base 14 is connected to the front shell 11. Specifically, the first drain hole 101 includes a front drain hole 1011 and a side drain hole 1012. The front drain hole 1011 is opposite to the lower area below the front of the housing 10, and the side drain holes 1012 are respectively opposite to the lower areas on the two sides of the housing 10. Side drain holes 1012 are provided on both sides of the front drain hole 1011. The number of the front drain hole 1011 and the side drain holes 1012 can be one or more. In this embodiment, there are a total of four front drain holes 1011, which are distributed at intervals. There are a total of six side drain holes 1012, with three provided on each side of the front drain hole 1011, and they are distributed at intervals.

[0071] The second drain hole 102 is provided on the rear shell 12 and is used to drain the liquid leaked from the water tank 20 when the humidifying device is tilted backward. As Figure 1 and Figure 12 shown, in this embodiment, the second drain hole 102 is located at the air inlet, and the liquid is discharged outside the humidifying device through the grille at the air inlet. In other embodiments, the second drain hole 102 can be separated from the air inlet. Specifically, it can be provided below the air inlet, or opposite to another opening on the back of the water tank 20 accommodating part facing the humidifying device. Its shape can be set as a plurality of small holes or in a grille shape.

[0072] As Figures 4 to 6 、 Figures 10 to 12 shown, the humidifying device further includes a volute 60.

In this embodiment, the volute 60 and the water separation part 40 are integrally formed. In other embodiments, the volute 60 can be a separate component and is combined with the water separation part 40 by means of snap connection or the like.

[0073] As Figure 6 and Figure 9 shown, the main control board waterproof part 42 is provided outside the blow port 90 of the volute 60, extends from the base 14 towards the top shell 13 and surrounds the main control board 31, and is used to block the liquid from flowing into the main control board 31. One side of the main control board waterproof part 42 faces the main control board 31, and the other side is in contact with the front shell 11.

[0074] As Figure 6 and Figure 8As shown, the humidifying device further includes a circuit board box 33, and the circuit board box 33 is disposed on the water separation part 40. A circuit board box receiving part 43 is provided on the water separation part 40 for receiving the circuit board box 33. The circuit board box receiving part 43 extends in the direction of the front case 11 and contacts the front case 11. Further, the circuit board box receiving part 43 is located on one side of the air outlet 90 of the volute 60 and has a structure extending in the direction of the side surface facing the outer case 10, and contacts the side panel 112 of the front case 11 to form a space capable of surrounding the circuit board box 33. The shape of the circuit board box receiving part 43 is the same as that of the circuit board box 33. In this embodiment, the circuit board box 33 is in the shape of a cuboid, and the circuit board box receiving part 43 is a cuboid slightly larger than the circuit board box 33 so that the circuit board box receiving part 43 can accommodate the circuit board box 33. Specifically, three flat plates extend from one side of the air outlet 90 of the volute 60 in the direction of the side surface of the outer case 10. After the three flat plates are connected, the circuit board box receiving part 43 is provided with an opening facing the back direction of the outer case 10, and the opening can be covered by the structure of the filter placement part 70 described below. In other embodiments, the circuit board box receiving part 43 may be four flat plates extending from one side of the air outlet 90 of the volute 60 in the direction of the side panel 112 of the front case 11, and the four flat plates are vertically connected end to end to form a cuboid shape.

[0075] As Figure 8As shown, the circuit board box 33 includes a box body 331 and a box cover 332. The box body 331 is provided with a receiving port for accommodating the circuit board 32. The box cover 332 is used to cover the receiving port. The box body 331 is in a shape that can receive the circuit board 32. In this embodiment, the circuit board 32 is square, and the box body 331 is square. In order to smoothly put the circuit board 32 in, the receiving port is also square. The box cover 332 is roughly flat and consistent with the shape of the receiving port. The so-called roughly flat means that in order to connect the box body 331 with the box cover 332, the box cover 332 surrounds the periphery of the receiving port and extends a convex edge toward the box body 331, hereinafter referred to as the box cover convex edge. A waterproof structure 333 is provided between the box body 331 and the box cover 332. The waterproof structure 333 is a groove formed around the receiving port and is provided on the box body 331 and / or the box cover 332. Specifically, the waterproof structure 333 can be provided only on the box body 331, and the waterproof structure 333 is a groove formed by the L-shaped edges extending from the four sides of the storage opening of the box body 331 toward the outside of the box body 331 and the four sides of the box body 331, and the convex edge of the box cover 332 is inserted into the waterproof structure 333, so that the box body 331 and the box cover 332 form a closed space. The waterproof structure 333 can also be provided only on the box cover 332, and the waterproof structure 333 is a groove formed by the L-shaped edges extending from the convex edge of the box cover toward the outer circumference of the box cover 332 and the convex edge of the box cover, and the four sides of the storage opening of the box body 331 are inserted into the waterproof structure 333, so that the box body 331 and the box cover 332 form a closed space. In this embodiment, the waterproof structure 333 is provided on the box body 331 and the box cover 332, and the grooves of the box body 331 and the grooves of the box cover 332 overlap alternately, so that the box body 331 and the box cover 332 form a closed space. The so-called closed means that liquid can be prevented from flowing into the circuit board 32 through the connection position between the box body 331 and the box cover 332, causing the circuit board 32 to short-circuit.

[0076] like Figure 5 As shown, the humidifier further includes a filter placement portion 70. The filter placement portion 70 is disposed between the water-isolating portion 40 and the rear shell 12, and is used to place a filter. The filter is directly opposite to the air inlet and the suction port 80, and is disposed between the air inlet and the suction port 80, so as to filter and purify the air entering from the air inlet, so that the air is discharged from the air supply port through the suction port 80 via the inside of the volute 60. The filter placement portion 70 is also provided with a through port, so that the water tank 20 passes through the filter placement portion 70 and enters the water tank accommodating portion 41.

[0077] The water-isolating function of the water-isolating portion 40 of the humidifying device according to the embodiment of the present utility model will be described below according to the tilting direction of the humidifying device.

[0078] (1) The humidifier is tilted forward

[0079] When the humidifying device falls to the ground with its front side tilted, the liquid in the water tank 20 leaks out of the water tank 20. Since the water tank 20 is at least partially surrounded by the water tank accommodating portion 41, and the water tank accommodating portion 41 and the base 14 provided with the first drainage hole 101 form a hollow structure, the liquid cannot immediately flow around the inside of the humidifying device after the front side of the humidifying device is tilted, that is, the liquid is blocked by the inner side 411 of the water tank accommodating portion and fails to flow towards the top shell 13. Since the base 14 is provided with the first drainage hole 101, the liquid blocked by the inner side 411 of the water tank accommodating portion from flowing towards the top shell 13 gradually flows towards the base 14. Most of the liquid will first be discharged out of the humidifying device through the front drainage hole 1011. In the case of a large amount of liquid, after the water level of a part of the liquid reaches the position of the side drainage hole 1012, it will also be discharged through the side drainage hole 1012. And another part of the liquid that has not been discharged from the drainage hole will flow in along the gap between the front panel 111 of the front shell 11 and the outer side 412 of the water tank accommodating portion. Since the front shell 11 is provided with a retaining rib 51, the retaining rib 51 contacts the outer side 412 of the water tank accommodating portion, making it difficult for the liquid to pass through. And in the normal use state, the retaining rib 51 is arranged above the outer side 412 of the water tank accommodating portion, and the surrounding edge formed by the retaining rib 51 has a certain width, so that even if the liquid reaches the outer side 412 of the water tank accommodating portion, it is difficult to cross the retaining rib 51 and flow towards the electrical part. At this time, the liquid blocked by the retaining rib 51 will eventually also flow towards the base 14 and be discharged through the front drainage hole 1011.

[0080] (2) Humidifying device falls to the ground with its side tilted

[0081] When the humidifying device falls to the ground with its side tilted, the liquid in the water tank 20 leaks out of the water tank 20. Since the water tank 20 is at least partially surrounded by the water tank accommodating portion 41, and the water tank accommodating portion 41 and the base 14 provided with the first drainage hole 101 form a hollow structure, the liquid cannot immediately flow around the inside of the humidifying device after the side of the humidifying device is tilted, that is, the liquid is blocked by the inner side 411 of the water tank accommodating portion and fails to flow towards the top shell 13. Since the base 14 is provided with the first drainage hole 101, the liquid blocked by the inner side 411 of the water tank accommodating portion from flowing towards the top shell 13 gradually flows towards the base 14. Most of the liquid will first be discharged out of the humidifying device through the side drainage hole 1012. In the case of a large amount of liquid, after the water level of a part of the liquid reaches the position of the front drainage hole 1011, it will also be discharged through the front drainage hole 1011. And another part of the liquid that has not been discharged from the drainage hole will flow in along the gap between the side panel 112 of the front shell 11 and the outer side 412 of the water tank accommodating portion. Since the water blocking portion 40 is provided with a protruding rib 52, the protruding rib 52 contacts the fixing rib 113 of the front shell 11, strengthening the sealing performance and making it difficult for the liquid to flow towards the top shell 13.

[0082] The following mainly describes the water-blocking function of the water-blocking part 40 when the other side of the circuit board box 33 and the main control board 31 is tilted. The parts that are the same as the above description will not be repeated. When a small amount of liquid flows through the gap between the rib 52 and the fixing rib 113 to the circuit board box 33, since the water-blocking part 40 is provided with a circuit board box receiving part 43 that can accommodate the circuit board box 33, the side protruding edge of the circuit board box receiving part 43 facing the side of the housing 10 contacts the side panel 112 of the front case 11, making it difficult for the liquid to pass through the circuit board box receiving part 43 and contact the circuit board box 33. Even if a small amount of liquid flows into the circuit board box receiving part 43, since the circuit board box 33 is provided with a waterproof structure 333, the waterproof structure 333 is a structure in which the groove of the box body 331 and the groove of the box cover 332 are overlapped in an alternating manner, so that the box body 331 and the box cover 332 form a sealed space to prevent the liquid from flowing into the circuit board box 33 through the connection position between the box body 331 and the box cover 332, resulting in a short circuit of the circuit board 32. Further, since the water-blocking part 40 is also provided with a main control board waterproof part 42, which extends from the base 14 towards the top case 13 and surrounds the main control board 31, one side of the main control board waterproof part 42 faces the main control board 31, and the other side is attached to the front case 11, which can block the liquid from flowing into the main control board 31 through the gap between the front case 11 and the main control board waterproof part 42. And even if the liquid flows in through the direction of the top case 13, since the other side of the main control board waterproof part 42 is attached to the front case 11, it can also block the liquid from flowing into the main control board 31 through the gap between the front case 11 and the main control board waterproof part 42, effectively avoiding the short circuit caused by the main control board 31 getting wet. Under multiple protections, the waterproof performance of the humidifying device is improved, and the safety of the humidifying device is ensured.

[0083] (3)Backward tilting of the humidifying device

[0084] When the humidifying device is tilted backward to the ground, the liquid in the water tank 20 leaks out of the water tank 20. Since the filter placement part 70 is provided with a through hole, the liquid flows out from the through hole and spreads to the rear case 12. Since the rear case 12 is provided with a second drain hole 102, in this embodiment, the second drain hole 102 is provided at the air inlet, and the air inlet is provided with a grille structure, so that the liquid can flow out from the grille to the outside of the humidifying device, avoiding the safety risk of the liquid staying in the humidifying device.

[0085] In summary, the humidifying device of the present utility model has at least the following beneficial effects:

[0086] The water-blocking part 40 of the humidifying device of the present utility model includes a water tank receiving part 41, and the water tank receiving part 41 is structured to at least partially surround the water tank 20, so that the liquid leaked from the water tank 20 after the humidifying device is tilted cannot immediately flow around the inside of the humidifying device. That is, the liquid is blocked by the inner side 411 of the water tank receiving part and cannot flow towards the top case 13.

[0087] On the front shell 11 of the humidifying device of the present utility model, there is a retaining rib 51. The retaining rib 51 is in contact with the water tank accommodating part 41, making it difficult for liquid to pass through. And in the normal use state, the retaining rib 51 is located above the outer side 412 of the water tank accommodating part. The surrounding edge formed by the retaining rib 51 makes it difficult for the liquid to flow over the retaining rib 51 to the electrical part even if it reaches the outer side 412 of the water tank accommodating part, strengthening the sealing performance.

[0088] The base 14 of the humidifying device of the present utility model is provided with a first drain hole 101. The liquid blocked by the inner side of the accommodating part of the water tank 20 from flowing towards the top shell 13 will flow towards the base 14 and be discharged through the first drain hole 101, preventing the liquid from staying in the humidifying device and posing a safety risk.

[0089] The rear shell 12 of the humidifying device of the present utility model is provided with a second drain hole 102. When the humidifying device is tilted and lands on its back, the liquid can flow out of the humidifying device through the second drain hole 102, avoiding the liquid staying in the humidifying device and posing a safety risk.

[0090] The water blocking part 40 of the humidifying device of the present utility model is provided with a protruding rib 52. The protruding rib 52 is in contact with two opposite side surfaces of the front shell 11, making it difficult for the liquid overflowing from the water tank 20 to flow towards the top shell 13, strengthening the sealing performance.

[0091] The circuit board box 33 of the humidifying device of the present utility model is provided with a waterproof structure 333. The waterproof structure 333 forms a groove around the receiving opening and is provided on the box body 331 and / or the box cover 332 to form a sealed space between the box body 331 and the box cover 332, preventing the liquid from flowing into the circuit board box through the connection position between the box body 331 and the box cover 332, effectively avoiding the short circuit of the humidifying device caused by the circuit board 32 getting wet.

[0092] The water blocking part 40 of the humidifying device of the present utility model further includes a circuit board box receiving part 43 for accommodating the circuit board box 33. It is a structure extending towards the side surface facing the outer shell 10 and is in contact with the front shell 11 to form a sealed space, making it difficult for the liquid to pass through the circuit board box receiving part 43 to contact the circuit board box 33, effectively avoiding the short circuit of the humidifying device caused by the circuit board 32 getting wet.

[0093] The water isolation part 40 of the humidifying device of the present utility model further includes a main control board waterproof part 42, which extends from the base 14 towards the top shell 13 and is arranged around the main control board 31. One side of the main control board waterproof part 42 faces the main control board 31, and the other side is attached to the front shell 11, which can prevent liquid from flowing into the main control board 31 through the gap between the front shell 11 and the main control board waterproof part 42. And even if the liquid flows in through the direction of the top shell 13, since the other side of the main control board waterproof part 42 is attached to the front shell 11, it can also prevent the liquid from flowing into the main control board 31 through the gap between the front shell 11 and the main control board waterproof part 42, effectively avoiding the short circuit of the humidifying device caused by the wetting of the main control board 31.
