In this embodiment, the pressing piece 3 is a silicone pad. The pressing piece 3 can also be made of elastic materials such as acrylic glue, polyurethane glue, rubber, etc.

[0088] like Figures 10 to 13 As shown, a sealing member 6 is provided between the box body 11 and the box cover 12. Specifically, the sealing member 6 is provided between the top surface of the box body 11 and the top surface of the box cover 12. The top surface of the box cover 12 is the inner wall surface of the top plate body 121. The top surface of the box cover 12 is opposite to the top surface of the box body 11. The sealing member 6 is made of an elastic material, and the sealing member 6 can be a silicone pad. The sealing member 6 can also be made of elastic materials such as acrylic glue, polyurethane glue, rubber, etc.

[0089] In this embodiment, the sealing member 6 is a square surrounding structure as a whole, and is made of silicone. The sealing member 6 includes a covering portion 61 and a raised portion 62. The so-called covering here can be a complete surrounding cover or a partial surrounding cover. The covering portion 61 is arranged near the edge of the storage port, surrounding and covering the relative positions of the box body 11 and the box cover 12. In this embodiment, the covering portion 61 is arranged to surround and cover the box body 11. From the cross-section, the covering portion 61 is concave, and the concave position of the covering portion 61 is the top position of the four side walls surrounding the box body 11, and the top of the side wall here is the position of the side wall close to the top surface of the box body 11. It can be understood that the covering portion 61 is formed by two hollow rectangular surrounds of similar shape but different sizes being spliced ​​together through a connecting portion, hereinafter referred to as the large rectangular surround and the small rectangular surround, the large rectangular surround is arranged outside the small rectangular surround, and the connecting portion is the large rectangular surround extending toward the small rectangular surround, thereby connecting the large rectangular surround with the small rectangular surround, the large rectangular surround is opposite to the outer surfaces of the four side walls of the box body 11, and the small rectangular surround is opposite to the inner surfaces of the four side walls of the box body 11, that is, the side walls of the box body 11 are sandwiched between the large rectangular surround and the small rectangular surround.

[0090] The covering portion 61 includes an inner side 611 and an outer side 612 of the covering portion. The inner side 611 of the covering portion is a side facing the box body 11, that is, a recessed area surrounding a portion of the four side walls of the box body 11, and the outer side 612 of the covering portion is a side facing the box cover 12, that is, the opposite side of the inner side 611 of the covering portion.

[0091] The raised portion 62 is provided on the surface of the covering portion 61. In the present embodiment, the raised portion 62 is provided on the outer side 612 of the covering portion and is convex toward the box cover 12. From the cross-section, the raised portion 62 is a convex point in the middle of the outer side 612 of the covering portion. Specifically, from the overall perspective, the raised portion 62 is a raised edge extending from the top of the covering portion 61 to the top surface of the box cover 12. The raised portion 62 can conflict with the inner wall surface of the box cover 12, that is, the raised portion 62 can conflict with the top surface of the box cover 12.

[0092] The side of the cavity 102 facing the electrical box 1 is provided with an electrical mating part 7, specifically located between the two limiting parts 922, and the number of its electrical mating parts 7 is the same as that of the electrical connector 2, and the spacing distance of each electrical mating part 7 corresponds to the spacing distance of each electrical connector 2, so that the electrical mating part 7 and the electrical connector 2 can be smoothly aligned. The cavity 102 is provided with a waterproof fixing structure 8 that can fix the electrical mating part 7 and prevent liquid from entering. The waterproof fixing structure 8 is similar to the stacked structure formed by the electrical connector 2 passing through the pressing part 3, the contact plate fixing plate 4, and the contact plate 5 in sequence. Specifically, the waterproof fixing structure 8 includes a fastener 83, a contact fixing plate 82, and a second contact plate 81. The fastener 83, the contact fixing plate 82 and the second contact plate 81 are all provided with openings through which the electrical mating component 7 can pass, and the number of openings is the same. The plurality of electrical mating components 7 are arranged one by one with the openings of the plurality of fasteners 83, the openings of the plurality of contact fixing plates 82, and the openings of the plurality of second contact plates 81, and the electrical mating components 7 and the openings are arranged coaxially. Among them, the diameter of the opening of the fastener 83 is less than or equal to the diameter of the electrical mating component 7. The fastener 83 is in the shape of a flat plate and is made of an elastic material, so that even if the diameter of the opening of the fastener 83 is less than or equal to the diameter of the electrical mating component 7, the electrical mating component 7 can pass through the opening of the fastener 83 to achieve an interference fit. In this embodiment, the fastener 83 is a silicone pad.

[0093] The structure of the second embodiment is described below.

[0094] The same structures as those of the first embodiment will not be described in detail, and only the differences are described below.

[0095] Fig.14 It is a schematic diagram of a box body of a second embodiment of the utility model (with the sealing member removed); Fig.15 A schematic diagram of a box body according to a second embodiment of the present utility model (showing a sealing member); Fig.16 A schematic diagram of a box cover and a sealing member according to a second embodiment of the present invention; Fig.17 This is a schematic diagram of a sealing member according to a second embodiment of the present utility model; Fig.18 This is a second schematic diagram of a sealing member according to the second embodiment of the present utility model.

[0096] like Fig.14 and Fig.15 As shown, the electrical box 1 further includes a partition plate 13. The partition plate 13 is disposed in the electrical box 1, and is disposed near the position where the electrical connector 2 penetrates the electrical box 1, and the electrical connector 2 penetrates the partition plate 13. The partition plate 13 has two opposite sides, one side of the partition plate 13 and the inner wall surface of the box body 11 enclose a water storage area 14, and the other side of the partition plate 13 and the inner wall surface of the box body 11 enclose a storage area 15, and the electrical components are located in the storage area 15.

[0097] In this embodiment, the partition plate 13 is a plate-like body with a bend extending from the bottom surface of the box body 11 toward the top surface of the box body 11. The electrical connector 2 passes through the first side wall 111 of the box body 11, and the partition plate 13 is arranged close to the first side wall 111, and the middle section of the partition plate 13 is parallel to the first side wall 111. The box body 11 includes a first side wall 111, a second side wall, a third side wall and a fourth side wall, the first side wall 111 is opposite to the second side wall, the third side wall is opposite to the fourth side wall, and the two ends of the partition plate 13 are respectively connected to the third side wall and the fourth side wall of the box body 11. Due to the effect of the partition plate 13, the internal space of the electrical box 1 is divided into a water storage area 14 and a receiving area 15, and the volume of the receiving area 15 is greater than the volume of the water storage area 14. Correspondingly, the receiving port is also divided to form a first receiving port arranged above the water storage area.

[0098] Specifically, the water storage area, located near the edge of the storage port, is used to store water that has seeped in from the electrical connector 2, and to prevent the water that has seeped in from the electrical connector 2 from further flowing to the location where the electrical components are located. The curved sections at both ends of the partition plate 13 are formed to accommodate the shapes of the clamp 3 and the contact plate fixing plate 4. The partition plate 13, the clamp 3, the contact plate fixing plate 4 and the contact plate 5 form a structure that is stacked in sequence. The partition plate 13 is provided with through openings, and the number of the through openings is consistent with the number of the through openings, the waterproof openings, the fixing openings and the electrical connector 2, and the central axis of the through openings is on the same straight line as the central axis of the electrical connector 2, the through openings and the waterproof openings, so that the electrical connector 2 can smoothly pass through the through openings, the through openings, the waterproof openings and the fixing openings in sequence.

[0099] like Figures 15 to 18 As shown, a seal 6 is provided between the box body 11 and the box cover 12. Specifically, the seal 6 is provided between the top surface of the box body 11 and the top surface of the box cover 12. The seal 6 is a square surrounding structure as a whole, and includes a covering portion 61 and a protruding portion 62.

[0100] The covering portion 61 is disposed near the edge of the receiving opening, surrounding and covering the position where the box body 11 and the box cover 12 are opposite to each other. From the longitudinal section, the covering portion 61 is concave. Different from the first embodiment, a part of the concave position of the covering portion 61 is the top of the four side walls surrounding the box body 11, where the top of the side wall is the position where the side wall is close to the top surface of the box body 11, and the other part extends from a position close to and corresponding to the position where the electrical connector 2 passes through the electrical box 1 to the partition plate 13. Specifically, a part of the covering portion 61 extends from the top of the first side wall 111 to the top of the partition plate 13 to cover the first receiving opening corresponding to the water storage area 14. It can be understood that, different from the first embodiment, the small rectangular surrounding edge is an irregular rectangle. Specifically, due to the position of the partition plate 13, the position of the small rectangular surrounding edge close to the first side wall 111 is not located on the inner surface of the first side wall 111 of the box body 11 in this embodiment, but is located at the position where the partition plate 13 is away from the first side wall 111. In addition, the irregular rectangle here is also set according to the shape of the partition plate 13, so that the covering portion 61 and the partition plate 13 are closely fitted, and the sealing effect is better.

[0101] The covering portion 61 includes an inner side 611 and an outer side 612 . The inner side 611 is the side facing the box body 11 , that is, the recessed position surrounding the box body 11 . The outer side 612 is the side facing the box cover 12 , that is, the opposite side of the inner side 611 .

[0102] The raised portion 62 is disposed on the outer side 612 of the covering portion and faces the box cover 12. In this embodiment, from the longitudinal section, the raised portion 62 is a convex point on the outer side 612 of the covering portion. Specifically, the raised portion 62 is a raised edge extending from the upper side of the covering portion 61 to the top surface of the box cover 12. Different from the first embodiment, due to the partition plate 13, the raised portion 62 is also disposed at the position of the covering portion 61 above the partition plate 13. That is, from the cross section, the shape of the raised portion 62 is consistent with the shape of the box body 11 and the partition plate 13.

[0103] Next, the structure of the third embodiment will be described. Fig.19 A schematic diagram of an electrical box according to a third embodiment of the present invention (showing a seal)

[0104] The same structures as those of the second embodiment will not be described in detail, and only the differences are described below. Fig.19 As shown, the structure of the electrical box 1 of the third embodiment is the same as that of the second embodiment, and only the sealing member 6 is different.

[0105] The covering portion 61 is disposed near the edge of the receiving opening, surrounding and covering the relative positions of the box body 11 and the box cover 12. Specifically, the concave position of the covering portion 61 is the top position of the four side walls surrounding the box body 11 and the top position of the partition plate 13, where the top of the side wall is the position of the side wall close to the top surface of the box body 11, and the top of the partition plate 13 is the position of the partition plate 13 close to the top surface of the box body 11. Different from the second embodiment, the covering portion 61 does not cover the first receiving opening corresponding to the water storage area 14, but is a hollow structure disposed around the edge of the first receiving opening.

[0106] Next, the structure of the fourth embodiment will be described. Fig. 20 This is a simplified cross-sectional view of an electrical box according to a fourth embodiment of the present invention.

[0107] The structures of the fourth embodiment that are the same as those of the first embodiment will not be described in detail, and only the differences are described below. Fig. 20 As shown, the shape of the sealing member 6 is the same as that of the first embodiment, but due to the different structure of the box cover 12, the installation direction and position are also different.

[0108] The main point is that the box cover 12 also includes a rib 123. The rib 123 is a rib that protrudes from the top plate 121 of the box cover 12 toward the box body 11 and is formed along the edge of the receiving opening. The covering portion 61 surrounds and covers the rib 123, and the rib 123 is embedded in the covering portion 61 of the sealing member 6.

[0109] The covering portion 61 includes an inner side 611 and an outer side 612 of the covering portion. The inner side 611 of the covering portion is a side facing the box cover 12, that is, a concave position surrounding the rib 123 of the box cover 12, and the outer side 612 of the covering portion is a side facing the box body 11, that is, the other side opposite to the inner side 611 of the covering portion. The raised portion 62 is provided on the outer side 612 of the covering portion and faces the box body 11. The raised portion 62 is opposite to the top surface of the box body 11, and the raised portion 62 can conflict with the top surface of the box body 11.

[0110] When assembling the box body 11, the seal 6 and the box cover 12, first align the inner side 611 of the covering portion of the seal 6 with the rib 123 of the box cover 12, and apply external force to the seal 6 so that the rib 123 is pressed into the inner side 611 of the covering portion, thereby completing the assembly of the seal 6 and the box cover 12. Then, the box cover 12 is buckled at the receiving opening of the box body 11, and external force is applied to the box cover 12, so that the outer side 612 of the covering portion of the seal 6 fits with the top surface of the box body 11, and the protrusion 62 contacts the top surface of the box body 11, thereby completing the assembly of the box body 11, the seal 6 and the box cover 12.

[0111] Optionally, a concave portion is formed by the top surface of the side wall of the box body 11 being concave downward, and the concave portion is extended along the circumferential direction of the box body 11, and the concave portion is adapted to the convex portion 62, and the convex portion 62 can be embedded in the concave portion. The convex portion 62 is embedded in the concave portion, which is conducive to further improving the sealing performance.

[0112] Next, the structure of the fifth embodiment will be described. Fig.21 This is a simplified cross-sectional view of an electrical box according to a fifth embodiment of the present invention.

[0113] The structures of the fifth embodiment that are the same as those of the second embodiment will not be described in detail, and only the differences are described below. Fig.21 As shown, the shape of the sealing member 6 is the same as that of the second embodiment, but due to the different structure of the box cover 12, the installation direction and position are also different.

[0114] The main point is that the box cover 12 further includes a rib 123. The rib 123 is a rib that protrudes from the top plate 121 of the box cover 12 toward the box body 11 and is formed along the edge of the receiving opening. The covering portion 61 is arranged around and covers the rib 123.

[0115] The covering portion 61 includes an inner side 611 and an outer side 612 of the covering portion. The inner side 611 of the covering portion is a side facing the box cover 12, that is, a concave position of the rib 123 surrounding the box cover 12, and the outer side 612 of the covering portion is a side facing the box body 11, that is, the other side opposite to the inner side 611 of the covering portion. The raised portion 62 is provided on the outer side 612 of the covering portion and faces the box body 11. A part of the raised portion 62 is opposite to the top surface of the box body 11, and a part of the raised portion 62 is opposite to the top surface of the partition plate 13.

[0116] When assembling the box body 11, the seal 6 and the box cover 12, first align the inner side 611 of the covering portion of the seal 6 with the rib 123 of the box cover 12, and apply external force to the seal 6 so that the rib 123 is pressed into the inner side 611 of the covering portion, thereby completing the assembly of the seal 6 and the box cover 12. Then, the box cover 12 is buckled at the receiving opening of the box body 11, and external force is applied to the box cover 12, so that the outer side 612 of the covering portion of the seal 6 fits with the top surface of the box body 11 and the top surface of the partition plate 13, and the protrusion 62 contacts the top surface of the box body 11 and the top surface of the partition plate 13, thereby completing the assembly of the box body 11, the seal 6 and the box cover 12.

[0117] Optionally, the top surface of the side wall of the box body 11 is recessed downward to form a first recessed portion, and the top surface of the partition plate 13 is recessed downward to form a second recessed portion, the first recessed portion is extended along the circumferential direction of the box body 11, and the second recessed portion is extended along the length direction of the partition plate 13. The first recessed portion and the second recessed portion are both matched with the raised portion 62, and the raised portion 62 can be embedded in the first recessed portion and the second recessed portion. The raised portion 62 is embedded with the first recessed portion and the second recessed portion, which is conducive to further improving the sealing performance.

[0118] Next, the structure of the sixth embodiment will be described. Fig. 22 It is a simplified cross-sectional view of an electrical box according to a sixth embodiment of the present utility model.

[0119] The same structures as those of the third embodiment will not be described in detail, and only the differences are described below. Fig. 22 As shown, the shape of the sealing member 6 is the same as that of the third embodiment, but due to the different structure of the box cover 12, the installation direction and position are also different.

[0120] The main point is that the box cover 12 also includes a protruding rib 123. The protruding rib 123 is a peripheral edge that protrudes from the top plate 121 of the box cover 12 toward the box body 11 and is arranged along the edge of the storage opening. The covering portion 61 surrounds and covers the protruding rib 123. The protruding rib 123 includes a first protruding rib 1231 opposite to the top surface of the box body 11 and a second protruding rib 1232 opposite to the top surface of the partition plate 13.

[0121] The covering portion 61 includes an inner side 611 and an outer side 612 of the covering portion. The inner side 611 of the covering portion is a side facing the box cover 12, that is, a concave position surrounding the first protruding rib 1231 and the second protruding rib 1232 of the box cover 12. The outer side 612 of the covering portion is a side facing the box body 11, that is, the other side opposite to the inner side 611 of the covering portion. The raised portion 62 is provided on the outer side 612 of the covering portion and faces the box body 11. A part of the raised portion 62 is opposite to the top surface of the box body 11, and a part of the raised portion 62 is opposite to the top surface of the partition plate 13.

[0122] When assembling the box body 11, the seal 6 and the box cover 12, first align the inner side 611 of the covering portion of the seal 6 with the first protruding rib 1231 and the second protruding rib 1232 of the box cover 12, and apply external force to the seal 6 so that the first protruding rib 1231 and the second protruding rib 1232 are pressed into the inner side 611 of the covering portion 61, thereby completing the assembly of the seal 6 and the box cover 12. Then, the box cover 12 is buckled at the receiving opening of the box body 11, and external force is applied to the box cover 12, so that the outer side 612 of the covering portion of the seal 6 fits with the top surface of the box body 11 and the top surface of the partition plate 13, and the protruding portion 62 contacts the top surface of the box body 11 and the top surface of the partition plate 13, thereby completing the assembly of the box body 11, the seal 6 and the box cover 12.

[0123] The implementation methods of the first embodiment, the second embodiment, the third embodiment and the fourth embodiment of the present utility model are described in detail below. The implementation methods of other embodiments may refer to the implementation methods of the first embodiment, the second embodiment, the third embodiment and the fourth embodiment.

[0124] Implementation of the first embodiment:

[0125] When the water tank 91 needs to be cleaned, the water tank 91 is taken out of the cavity 102 of the humidifying device 100. After the water tank 91 is taken out as a whole, the water tank cover 911 is opened to clean the water tank cover 911. During the cleaning process, water will splash onto the outer surface of the box cover 12. The top surface of the box cover 12 is located outside the top surface of the box body 11, covering the storage port of the electrical box 1. The four side plates 122 and the top plate 121 of the box cover 12 surround the four side walls of the box body 11, forming a structure that can wrap the box body 11, so that it is difficult for water to enter between the box body 11 and the box cover 12. Even if a small amount of water enters between the box body 11 and the box cover 12, since a sealing member 6 is provided between the box body 11 and the box cover 12, the sealing member 6 is an elastic silicone pad, which improves the sealing between the top surface of the box body 11 and the top surface of the box cover 12. In addition, the sealing member 6 is provided with a covering portion 61 and a protruding portion 62. The concave position of the covering portion 61 is the top position of the four side walls surrounding the box body 11, and it is difficult for water to enter the electrical box 1 from between the inner side 611 of the covering portion and the box body 11. The raised portion 62 is a raised edge extending from the upper side of the covering portion 61 to the top surface of the box cover 12, which can make the seal 6 fit the box cover 12 more closely. Even if the top surface of the box cover 12 is uneven, the outer side 612 of the covering portion can be compressed to contact the top surface of the box cover 12, so that it is difficult for water to enter the electrical box 1 from between the outer side 612 of the covering portion and the box cover 12, thereby preventing the electrical components in the electrical box 1 from being soaked in water and causing a short circuit in the product.

[0126] In addition, during the cleaning process of the water tank cover 911, water may also splash onto the electrical connector 2 exposed outside the electrical box 1. When the water passes through the through-hole along the electrical connector 2, the pressing member 3 is provided near the position where the electrical box 1 and the electrical connector 2 are connected, and the pressing member 3 is in close contact with the electrical connector 2. The pressing member 3 is an elastic silicone pad, and the diameter of the waterproof opening is less than or equal to the diameter of the electrical connector 2, which can achieve an interference fit between the waterproof opening and the electrical connector 2, so that the waterproof opening is in close contact with the electrical connector 2, so that the water is blocked at the waterproof opening, and it is difficult to enter the fixed opening through the waterproof opening and reach the contact plate 5 in the electrical box 1, thereby improving the sealing of the electrical box 1 and ensuring the safety of the humidifier 100.

[0127] When cleaning is completed, the water tank cover 911 is installed and fixed back on the water tank 91, and the water tank 91 is aligned with the cavity 102 and pushed in. At the same time, the guide part 921 of the electrical box 1 is aligned with the limiting part 922 of the cavity 102. Since the guide part 921 is provided with a first sliding surface 9211 and a second sliding surface 9212, and the limiting part 922 is provided with a first guide surface 9221 and a second guide surface 9222, when the guide part 921 is pushed in, its "knife tip" position will first contact with the second guide surface 9222, so that it slides toward the inside of the slot 9223, and then the first sliding surface 9211 contacts with the first guide surface 9221. Under the guidance of the first guide surface 9221, the first sliding surface 9211 slides over the first guide surface 9221, so that the guide part 921 smoothly enters the inside of the slot 9223. After fully entering, the second guide surface 9222 fits with the second sliding surface 9212. In addition, since the slot 9223 is a matching structure with a wide entrance and a narrow interior, after the guide part 921 enters the slot 9223 , the guide part 921 is not likely to slide out due to the narrow interior.

[0128] The guide portion 921 and the limiting portion 922 cooperate with each other to precisely align the electrical fitting 7 with the electrical connector 2. At the same time, the box cover 12 is fixed in the cavity 102, which prevents the box cover 12 from deforming during use, thereby preventing a larger gap between the box body 11 and the box cover 12, or a larger gap between the box body 11 and the contact plate fixing plate 4, which makes it easier for liquid to enter the electrical box 1. Moreover, after alignment, the risk of the electrical fitting 7 and the electrical connector 2 being loosened during use can be reduced.

[0129] Implementation method of the second embodiment:

[0130] The implementations of the second embodiment that are the same as those of the first embodiment will not be described in detail, and only the differences are described below.

[0131] When water passes through the through-hole along the electrical connector 2, since the electrical box 1 is provided with a partition plate 13, the water that passes through the through-hole enters the water storage area 14 along the electrical connector 2. At this time, part of the water will remain in the water storage area 14, and the other part will flow along the electrical connector 2 to the waterproof port.

[0132] The water remaining in the water storage area 14, under normal installation conditions, will generally flow to the bottom of the water storage area 14 due to gravity until it reaches the height of the electrical connector 2 and then flows along the electrical connector 2 to the waterproof port. Even if the water tank cover 911 is swung at any angle during the cleaning process, since the covering portion 61 covers the first receiving port corresponding to the water storage area 14, it is difficult for the water entering the water storage area 14 to enter the receiving area 15 from between the inner side 611 of the covering portion and the top surface of the box body 11 and the top surface of the partition plate 13, thereby preventing the electrical components in the electrical box 1 from being soaked in water and causing a short circuit in the product.

[0133] The other part of the water flowing along the electrical connector 2 to the waterproof port can be prevented from flowing due to the presence of a pressing member 3 between the partition plate 13 and the contact plate fixing plate 4. The pressing member 3 is an elastic silicone pad, and the diameter of the waterproof port is less than or equal to the diameter of the electrical connector 2. The waterproof port can be tightly fitted with the electrical connector 2, so that the water is blocked at the waterproof port and is difficult to enter the fixing port through the waterproof port and reach the contact plate 5, thereby improving the sealing performance and ensuring the safety of the humidifier 100. The waterproof performance of the electrical box 1 is further improved by providing the partition plate 13.

[0134] Implementation method of the third embodiment:

[0135] The implementations of the third embodiment that are the same as those of the second embodiment are not described in detail, and only the differences are described below.

[0136] The water passing through the through hole enters the water storage area 14 along the electrical connector 2 . At this time, part of the water will remain in the water storage area 14 , and the other part will flow along the electrical connector 2 to the waterproof port.

[0137] Since the covering portion 61 covers the top of the partition plate 13, it is difficult for water in the water storage area 14 to enter the storage area 15 from between the inner side 611 of the covering portion and the partition plate 13, thereby preventing the electrical components in the storage area 15 from being soaked in water and causing a product short circuit.

[0138] Implementation method of the fourth embodiment:

[0139] The implementations of the fourth embodiment that are the same as those of the first embodiment are not described in detail, and only the differences are described below.

[0140] The seal 6 is provided with a covering portion 61 and a raised portion 62. The recessed position of the covering portion 61 is the position of the rib 123 surrounding the box cover 12, so that it is difficult for water to enter the electrical box 1 from between the inner side 611 of the covering portion and the box cover 12. The raised portion 62 is a raised edge extending from the upper side of the covering portion 61 toward the top surface of the box body 11, so that the seal 6 can fit the box body 11 more closely. Even if the top surface of the box body 11 is uneven, the outer side 612 of the covering portion can be brought into contact with the top surface of the box body 11 by compressing the raised portion 62, so that it is difficult for water to enter the electrical box 1 from between the outer side 612 of the covering portion and the box body 11, thereby preventing the electrical components in the electrical box 1 from being soaked in water and causing a short circuit in the product.

[0141] In summary, the humidifying device 100 of the present invention has at least the following beneficial effects:

[0142] The humidifier 100 of the present invention is provided with a clamping piece 3 near the position where the electrical connector 2 is connected to the electrical box 1. The clamping piece 3 is an elastic silicone pad. The diameter of the waterproof port is less than or equal to the diameter of the electrical connector 2, and an interference fit between the waterproof port and the electrical connector 2 can be achieved, so that the waterproof port is tightly in contact with the electrical connector 2, so that water is blocked at the waterproof port, and it is difficult to enter the fixed port through the waterproof port and reach the contact plate 5 in the electrical box 1, thereby improving the sealing of the electrical box 1 and ensuring the safety of the humidifier 100.

[0143] The number of electrical connectors 2, through-holes and waterproof openings of the humidifier 100 of the present invention is consistent, and the electrical connectors 2, through-holes and waterproof openings are coaxially arranged to make the assembly more rigorous, prevent gaps caused by deviation during penetration, and ensure sealing.

[0144] A sealing member 6 is provided between the box body 11 and the box cover 12 of the humidifying device 100 of the present invention. The sealing member 6 includes a covering portion 61 and a raised portion 62. The covering portion 61 is arranged near the edge of the storage port, surrounding and covering the relative positions of the box body 11 and the box cover 12, so that it is difficult for water to enter the electrical box 1 from between the box body 11 and the box cover 12. The raised portion 62 is a protrusion provided on the covering portion 61, which can make the sealing member 6 fit more closely with the box body 11 or the box cover 12. Even if the relative positions of the box body 11 and the box cover 12 are uneven, the contact area of ​​the outer side 612 of the covering portion can be increased by compressing the raised portion 62, so that it is difficult for water to enter the electrical box 1 from between the box body 11 and the box cover 12, thereby preventing the electrical components in the electrical box 1 from being wetted and causing a short circuit in the product.

[0145] The electrical box 1 of the humidifying device 100 of the present invention also includes a partition plate 13, which can prevent water that has penetrated from the electrical connector 2 from continuing to penetrate into the location of the electrical components, and a portion of the covering portion 61 extends from a position close to and corresponding to the position where the electrical connector 2 passes through the electrical box 1 to the partition plate 13, thereby forming a closed space, making it difficult for water that has entered the water storage area 14 to enter the storage area 15 from between the partition plate 13 and the box cover 12, thereby preventing the electrical components in the electrical box 1 from getting wet and causing a product short circuit, thereby further improving the waterproofness of the electrical box 1.

[0146] The guide structure 92 of the humidifying device 100 of the present invention includes a guide portion 921 and a limit portion 922. The guide portion 921 and the limit portion 922 cooperate with each other to accurately align the electrical connector 2 with the electrical matching component 7. At the same time, the box cover 12 is fixed in the cavity 102, which also prevents the box body 11 and the box cover 12 from being deformed during use, thereby preventing a larger gap from being formed between the box body 11 and the contact plate fixing plate 4, thereby making it easier for liquid to enter the electrical box 1. Moreover, after alignment, the risk of the electrical connector 2 and the electrical matching component 7 being loosened during use can be reduced.
