[0005] The humidifier of the present invention includes a main unit and a heating element, the main unit includes a base and a water tank, the water tank is arranged on the upper side of the base and connected to the base, the water tank is provided with a first clamping part, and the base is provided with a first conductive part; the heating element is arranged in the water tank, the heating element is provided with a second clamping part and a second conductive part, the second clamping part is clamped with the first clamping part, and the second conductive part is detachably connected to the first conductive part.

[0006] The humidifier of the present invention is provided with a first clamping portion on the water tank, a first conductive portion on the base, and a second clamping portion and a second conductive portion on the heating element. The second clamping portion is clamped with the first clamping portion to achieve connection between the heating element and the water tank, and the second conductive portion is connected with the first conductive portion to achieve electrical connection between the heating element and the host. When it is necessary to clean the scale on the heating element, the second clamping portion is separated from the first clamping portion, and the second conductive portion is separated from the first conductive portion, so that the heating element can be disassembled, thereby improving the convenience of disassembly of the heating element and making it easier for users to clean the heating element.

[0007] Optionally, one of the first conductive part and the second conductive part is a conductive plate, and the other of the first conductive part and the second conductive part is a conductive needle, and the conductive needle is in contact with the conductive plate.

[0008] By bringing the conductive pins into contact with the conductive plate, the electrical connection between the heating element and the main unit is achieved. This allows the heating element to be removed from the main unit simply by separating the second clipping portion from the first clipping portion, eliminating the need to specifically remove the electrical connection between the heating element and the main unit. This further improves the ease of disassembly and cleaning of the heating element.

[0009] Optionally, one of the first conductive part and the second conductive part is a conductive plate, and the other of the first conductive part and the second conductive part is a conductive needle, and the conductive needle is in contact with the conductive plate.

[0015] By arranging the slot opening toward one side of the water tank, the slot and the buckle can be reliably positioned in the vertical direction, thereby improving the connection reliability between the heating element and the water tank.

[0018] By aligning the first and second mating surfaces, the reliability of the connection between the heating element and the water tank can be improved. By arranging the first mating surface to gradually tilt downward away from the slot, the first and second mating surfaces gradually align as the clip is inserted into the slot, and gradually separate as the clip is removed from the slot. Thus, even if there are machining errors between the first and second mating surfaces, the connection and removal of the clip to the slot can be guaranteed, thereby improving the reliability of the humidifier.

[0019] By providing a plurality of first and second clamping portions, the connection reliability between the heating element and the water tank can be improved, further improving the reliability of the humidifier.

[0021] Optionally, the base body further includes a connecting base, the connecting base being connected to the base, and the conductive base being connected to the connecting base. By providing the connecting base, the connecting base can be configured as an insulating base, thereby achieving insulation between the conductive base and the base.

[0022] Optionally, the conductive seat is arranged on the lower side of the connecting seat; the connecting seat is provided with a plurality of through-holes, the number of the first conductive parts is multiple, the first conductive parts correspond to the through-holes one by one, and each of the first conductive parts protrudes upward from the corresponding through-hole.

[0023] By arranging the corresponding perforation for each first conductive part to protrude upward, not only can the insulation between two adjacent first conductive parts be achieved by utilizing the hole wall of the perforation, but also the position limitation of the connecting seat and the conductive seat in the circumferential direction of the water tank can be achieved.

[0024] Optionally, the connecting base is provided with a third clamping portion, and the conductive base is provided with a fourth clamping portion, wherein the third clamping portion is clamped with the fourth clamping portion.

[0025] Optionally, the heating element includes a mounting seat and a heating element, the heating element is connected to the mounting seat, the second clamping portion is provided on the mounting seat, and the second conductive portion is provided on the heating element.

[0026] By configuring the heating element to include a mounting base and a heating element, and arranging the second clamping portion on the mounting base, the structure of the original heating element can be maintained, or only the structure of the second conductive portion of the original heating element can be changed.

[0045] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0046] like Figures 1 to 3 As shown, the humidifier 100 of the embodiment of the present invention includes a main unit and a heating element 3. The main unit includes a base 1 and a water tank 2. The water tank 2 is arranged on the upper side of the base 1 and connected to the base 1. The water tank 2 is provided with a first clamping portion 201, the base 1 is provided with a first conductive portion 101, and the heating element 3 is provided with a second clamping portion 301 and a second conductive portion 302. The second clamping portion 301 is clamped to the first clamping portion 201, and the second conductive portion 302 is detachably connected to the first conductive portion 101.

[0047] The humidifier 100 of the embodiment of the present invention is provided with a first clamping portion 201 on the water tank 2, a first conductive portion 101 on the base 1, and a second clamping portion 301 and a second conductive portion 302 on the heating element 3. The second clamping portion 301 is clamped with the first clamping portion 201 to achieve connection between the heating element 3 and the water tank 2, and the second conductive portion 302 is connected with the first conductive portion 101 to achieve electrical connection between the heating element 3 and the host. When it is necessary to clean the scale on the heating element 3, the second clamping portion 301 is separated from the first clamping portion 201, and the second conductive portion 302 is separated from the first conductive portion 101, so that the heating element 3 can be disassembled, thereby improving the convenience of disassembling the heating element 3 and making it easier for users to clean the heating element 3.

[0048] In some embodiments, as Figure 3 and Figure 4 As shown, one of the first conductive part 101 and the second conductive part 302 is a conductive plate, and the other of the first conductive part 101 and the second conductive part 302 is a conductive needle, which contacts the conductive plate.

[0049] For example, the first conductive part 101 is a conductive plate, and the second conductive part 302 is a conductive needle.

[0050] By contacting the conductive pins with the conductive plate, the electrical connection between the heating element 3 and the main unit is achieved. When removing the heating element 3, the heating element 3 can be removed from the main unit by simply separating the second clamping portion 301 from the first clamping portion 201. There is no need to specifically remove the electrical connection between the heating element 3 and the main unit. This further improves the ease of disassembly of the heating element 3 and makes it easier for the user to clean the heating element 3.

[0051] Alternatively, as Figure 3 and Figure 4 As shown, the conductive pin is a spring conductive pin.

[0052] By setting the conductive needle as a spring conductive needle, elastic contact is achieved between the first conductive part 101 and the second conductive part 302 , which is beneficial to improving the contact reliability of the first conductive part 101 and the second conductive part 302 , thereby improving the reliability of the humidifier 100 .

[0053] In some embodiments, as Figure 3 、 Figures 5 to 7 As shown, one of the first clamping portion 201 and the second clamping portion 301 is a clamping slot, and the other of the first clamping portion 201 and the second clamping portion 301 is a buckle.

[0054] For example, the first clamping portion 201 is a clamping slot, and the second clamping portion 301 is a buckle, and the buckle is clamped with the clamping slot.

[0055] By setting one of the first clamping portion 201 and the second clamping portion 301 as a clamping slot and the other as a buckle, not only the structures of the first clamping portion 201 and the second clamping portion 301 are simplified, but also the processing and manufacturing of the humidifier 100 is facilitated.

[0056] Optionally, the notch 202 of the card slot faces one circumferential side of the water tank 2 , so that the buckle is engaged with or separated from the card slot when the heating element 3 rotates along the circumference of the water tank 2 .

[0057] For example, when the heating element 3 rotates clockwise, the buckle comes out of the slot opening 202, so that the buckle is separated from the slot; when the heating element 3 rotates counterclockwise, the buckle enters the slot through the slot opening 202, so that the buckle is engaged with the slot.

[0058] By arranging the notch 202 of the card slot toward one side of the circumference of the water tank 2, the card slot and the buckle can be reliably limited in the vertical direction, thereby improving the connection reliability between the heating element 3 and the water tank 2. In addition, the heating element 3 can be disassembled by rotating it, further improving the convenience of disassembly of the heating element 3.

[0059] Optionally, the upper side wall of the slot forms a first mating surface, and the first mating surface is arranged to gradually tilt downward in a direction away from the slot opening 202. Figure 7 As shown, the upper surface of the buckle forms a second mating surface 3011, and the second mating surface 3011 is in contact with the first mating surface.

[0060] It is understandable that there may be processing errors between the first mating surface and the second mating surface 3011. If the first mating surface and the second mating surface 3011 are both set to be parallel to the horizontal plane, it may cause the buckle to be difficult to mate with the slot.

[0061] By aligning the first and second mating surfaces, the connection reliability between the heating element 3 and the water tank 2 can be improved. By arranging the first mating surface to gradually tilt downward away from the notch 202, the first and second mating surfaces gradually align during insertion of the clip into the slot, and gradually separate during removal from the slot. Thus, even if there are machining errors between the first and second mating surfaces 3011, the connection and removal of the clip to the slot can be ensured, thereby improving the reliability of the humidifier 100.

[0062] Optionally, there are multiple first clamping parts 201 and multiple second clamping parts 301 , and the multiple first clamping parts 201 are arranged at intervals along the circumference of the water tank 2 , and the second clamping parts 301 correspond to the first clamping parts 201 one by one.

[0063] For example, the number of the first clamping portions 201 and the number of the second clamping portions 301 are both three, and the three first clamping portions 201 are evenly spaced along the circumference of the water tank 2 .

[0064] By providing a plurality of the first clamping parts 201 and the second clamping parts 301 , the connection reliability between the heating element 3 and the water tank 2 can be improved, and the reliability of the humidifier 100 can be further improved.

[0065] In some embodiments, as Figure 1 、 Figure 3 and Figure 4 As shown, the base body 1 includes a base 11 and a conductive base 12 . The conductive base 12 is detachably connected to the base 11 , and the first conductive portion 101 is disposed on the conductive base 12 .

[0066] By configuring the seat body 1 to include the base 11 and the conductive seat 12 , the conductive seat 12 is detachably connected to the base 11 , so that the conductive seat 12 can be replaced.

[0067] Alternatively, as Figure 1 、 Figure 3 and Figure 4As shown, the base body 1 further includes a connecting base 13 , which is connected to the base 11 , and the conductive base 12 is connected to the connecting base 13 .

[0068] It is understandable that the first conductive portion 101 and the base 11 need to be insulated.

[0069] By providing the connecting base 13, the connecting base 13 can be set as an insulating base, and the insulating base is used to achieve insulation between the conductive base 12 and the base 11. In this way, insulation between the first conductive part 101 and the base 11 is easily achieved.

[0070] Alternatively, as Figure 4 As shown, the conductive base 12 is disposed on the lower side of the connecting base 13. The connecting base 13 is provided with a plurality of through-holes 131. There are a plurality of first conductive portions 101, and the plurality of first conductive portions 101 correspond to the plurality of through-holes 131 one by one. Each first conductive portion 101 protrudes upwards from the corresponding through-hole 131.

[0071] For example, the number of the through-holes 131 and the number of the first conductive parts 101 are both two, one of the first conductive parts 101 is electrically connected to the positive pole of the power supply, and the other first conductive part 101 is electrically connected to the negative pole of the power supply.

[0072] By setting the corresponding through hole 131 protruding upward from each first conductive part 101, not only can the hole wall of the through hole 131 be used to achieve insulation between two adjacent first conductive parts 101, but also the connection seat 13 and the conductive seat 12 can be limited in the circumferential direction of the water tank 2.

[0073] Alternatively, as Figure 3 As shown, the connecting seat 13 is provided with a third clamping portion 132 , and the conductive seat 12 is provided with a fourth clamping portion 121 . The third clamping portion 132 is clamped with the fourth clamping portion 121 .

[0074] By engaging the third engaging portion 132 with the fourth engaging portion 121 , the connection between the connecting seat 13 and the conductive seat 12 is achieved, which facilitates the disassembly of the connecting seat 13 and the conductive seat 12 , thereby further facilitating the replacement of the conductive seat 12 .

[0075] Optionally, the connecting base 13 and the water tank 2 are connected via fasteners, for example, the connecting base 13 and the water tank 2 are connected via bolts or screws.

[0076] In some embodiments, as Figure 1 、 Figure 3 and Figure 4 As shown, the heating element 3 includes a mounting seat 31 and a heating element 32 . The heating element 32 is connected to the mounting seat 31 . The second clamping portion 301 is provided on the mounting seat 31 , and the second conductive portion 302 is provided on the heating element 32 .

[0077] The heating element 32 is used to heat the water in the water tank 2 .

[0078] By configuring the heating element 3 to include a mounting base 31 and a heating element 32, and disposing the second clamping portion 301 on the mounting base 31, the structure of the original heating element 32 can be maintained, or only the structure of the second conductive portion 302 of the original heating element 32 can be changed. This can reduce the design and manufacturing costs of the heating element 32, which is conducive to reducing the cost of the humidifier 100.

[0079] Alternatively, as Figure 3 and Figure 5 As shown, the heating element 3 further includes a sealing ring 33 , which is connected to the mounting seat 31 and is sealed with the water tank 2 .

[0080] By providing the sealing ring 33 , the sealing between the heating element 3 and the water tank 2 can be improved, thereby preventing the first conductive part 101 and the second conductive part 302 from contacting the water in the water tank 2 , thereby improving the safety of the humidifier 100 .

[0081] Alternatively, as Figure 3 and Figure 5 As shown, the sealing ring 33 and the mounting seat 31 are both annular. The sealing ring 33 is sleeved on the outside of the heating element 32 , and the mounting seat 31 is sleeved on the outside of the sealing ring 33 .

[0082] By designing the sealing ring 33 , the mounting seat 31 and the heating element 32 as described above, the assembly of the heating element 3 is facilitated, which is beneficial to improving the assembly efficiency of the humidifier 100 and reducing the cost of the humidifier 100 .

[0083] Optionally, the sealing ring 33 is a silicone ring, and the sealing ring 33 and the heating element 32 are interference fit, and the mounting seat 31 and the sealing ring 33 are interference fit.

[0084] like Figure 8 As shown, the humidifier 100 further includes a mist guide pipe 4 and an upper cover 5 . The upper cover 5 is connected to the water tank 2 . The mist guide pipe 4 is arranged in the water tank 2 . The heating element 3 is arranged in the mist guide pipe 4 .

[0085] In the humidifier 100 of the embodiment of the present utility model, the sealing ring 33 is sleeved on the heating element 32, and the mounting base 31 is sleeved on the sealing ring 33 to complete the assembly of the heating element 3. The first conductive part 101 of the conductive base 12 passes through the through-hole 131 of the connecting base 13, and the conductive base 12 is clamped with the connecting base 13. By rotating the heating element 3, the second clamping part 301 of the heating element 3 is clamped with the first clamping part 201 of the water tank 2. At the same time, the second conductive part 302 of the heating element 3 is in sliding contact with the first conductive part 101 of the conductive base 12 to supply power to the heating element 32 for heating. The heating element 32 heats the water in the mist guide tube 4, and the formed steam flows out through the outlet of the mist guide tube 4. The above design of the humidifier 100 improves the cleaning convenience of the heating element 3, and effectively improves the problem of low thermal efficiency of the heating element 3 due to the constant cleaning of the scale on the heating element 3.

[0086] Although the embodiments of the present invention have been shown and described above, it is understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments made by ordinary technicians in this field are all within the scope of protection of the present invention.
