Description

Technical Field

[0001] This utility model relates to the field of humidifiers, specifically a support structure for preventing deformation of the humidifier's straight outer shell components. Background Technology

[0002] The existing humidifier shell structure mainly consists of a lower shell and an upper shell connected to the upper side of the lower shell. However, due to the load-bearing requirements of the shell structure, most lower and upper shells are made of sheet metal to ensure that the shell structure will not deform or shrink. This significantly increases the production cost of the humidifier, thus affecting the product's competitiveness in the market. Therefore, some manufacturers consider using plastic materials such as PP to make the shell structure. However, the joint between the lower and upper shells (i.e., the open ends of the two facing each other) often exhibits problems such as... Figure 8 The deformation and shrinkage shown cause the joint between the lower and upper shells to not be fully aligned, increasing the difficulty of assembly and indirectly reducing production costs. Moreover, even after assembly, the location of deformation and shrinkage still affects the appearance of the humidifier. Therefore, the applicant has improved and perfected the existing structure to solve the above problems and make it available to consumers. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] First embodiment: See Figures 1 to 6As shown, a support structure for preventing deformation of the straight shell of a humidifier includes a rectangular shell assembly 1, a pot assembly 2, and a top cover 3. The pot assembly 2 is disposed inside the shell assembly 1. The top cover 3 is rotatably hinged to the top of the shell assembly 1 and encloses a steam generating chamber 5 between the top cover 3 and the pot assembly 2. The top cover 3 is provided with a steam exhaust channel 6 communicating with the steam generating chamber 5. The shell assembly 1 includes an upper shell 7 and a lower shell 8. The upper shell 7 and the lower shell 8 are fastened to each other by a shell support plate 9, and their opposing open ends are aligned and connected. The shell support plate 9 is located at the height where the upper shell 7 and the lower shell 8 are joined, and the four sides of the shell support plate 9 are in close contact with the inner wall surfaces of the upper shell 7 and the lower shell 8.

[0024] This humidifier is supported by an added outer shell support plate 9, which can correct the deformation of the upper shell 7 and the lower shell 8, and prevent deformation and shrinkage of the upper shell 7 and the lower shell 8 near the joint. The outer shell support plate also acts as a support and a connector, which can better solidify the outer shell assembly 1, improve the drop resistance of the humidifier, and make the entire outer shell of the humidifier possible to be made of plastic material, which can significantly reduce production costs. Moreover, it can also align the joint between the upper shell 7 and the lower shell 8, making the assembly more precise and faster, and improving production efficiency.

[0025] The outer shell support plate 9 has a hollow cavity 901 that matches the outer shape of the pot body assembly 2. The middle position of the pot body assembly 2 is limited within the hollow cavity 901 and forms a clearance fit with the outer shell support plate 9. In this embodiment, the height-to-width ratio of the pot body assembly 2 is large. Therefore, the pot body assembly 2 of the outer shell support plate 9 plays a supporting role and stabilizes the installation position of the pot body assembly 2.

[0026] The outer shell support plate 9 has an upper connecting column 91 extending upward from its rear side. The bottom surface of the top wall of the upper shell 7 is provided with an upper connecting component 10 suspended above the outer shell support plate 9. Through the installation and cooperation of the upper connecting component 10 and the upper connecting column 91, the rear side of the outer shell support plate 9 is fastened to the upper shell 7. In this embodiment, the upper connecting component 10 may include a fixed suspension column 101 and an offset connector 102. In this embodiment, the cross-section of the fixed suspension column 101 is approximately trapezoidal, and a first connecting column 103 extends from the bottom. It should be noted that the fixed suspension column 101 is coaxially arranged with the lower connecting component 11 described below. Therefore, by using the offset connector 102, the fastening positions of the outer shell support plate 9 and the upper connecting component 10 and the outer shell support plate 9 and the lower connecting component 11 are staggered, and their fastening positions do not interfere with each other. The offset connector 102 is provided with a first connection position 1021 and a second connection position 1022. The first connection position 1021 is provided with an insertion cavity 1023 suitable for the directional insertion of the fixed suspension column 101. The connection direction of the offset connector 102 is defined by the cooperation between the insertion cavity 1023 and the trapezoidal fixed suspension column 101. The first connection position 1021 is also provided with a first through hole 1024 corresponding to the first connection column 103. By passing a screw from bottom to top through the first through hole 1024 and the first connection position 1021, the offset connector 102 is securely connected to the bottom of the fixed suspension column 101.

[0027] The second connecting position 1022 is offset from the first connecting position 1021. The second connecting position 1022 extends downward to form a second connecting post 1025. The top of the upper connecting post 91 is provided with a second through hole 1026 corresponding to the second connecting post 1025. The upper connecting post 91 is fastened to the offset connector 102 by passing a screw from bottom to top through the second through hole 1026 and the second connecting post 1025.

[0028] It should also be noted that in other embodiments, the upper connecting component 10 may be a single fixed suspension column 101, which is offset from the lower connecting column 92 described below, and the upper connecting column 91 is directly fastened to the fixed suspension column 101 by screws.

[0029] The outer shell support plate 9 has a lower connecting post 92 extending downward from its rear side, and the bottom wall of the upper shell 7 has a lower connecting component 11 placed below the outer shell support plate 9. Through the installation and cooperation of the lower connecting component 11 and the lower connecting post 92, the rear side of the outer shell support plate 9 is fastened to the lower shell 8.

[0030] Specifically, the lower connecting assembly 11 includes a fixed sleeve 111 integrally connected to the bottom of the lower housing 8 and a telescopic sleeve 112 slidably connected inside the fixed sleeve 111. The top of the telescopic sleeve 112 has a third through hole 113 corresponding to the lower connecting post 92. After the screw passes through the fixed sleeve 111 and the telescopic sleeve 112, it passes through the third through hole 113 and the lower connecting post 92 from bottom to top, so that the outer shell support plate 9 is fastened to the telescopic sleeve 112.

[0031] The aforementioned upper connecting component 10 and lower connecting component 11 are mainly used to support the rear side of the housing support plate 9, while the front side of the housing support plate 9 is supported in the following way: The front end of the outer shell assembly 1 is also connected to a front cover assembly 4. The front cover assembly 4 includes a cover plate 41 and a panel 42 fastened to the surface of the cover plate 41. An upper mounting ear 43 extends from the middle of the panel 42, and a lower mounting ear 44 extends from the bottom of the cover plate 41. The upper mounting ear 43 is placed on the upper side of the outer shell support plate 9. Through the installation and cooperation of the upper mounting ear 43 and the outer shell support plate 9, the front side of the outer shell support plate 9 is fastened to the front cover assembly 4. The lower mounting ear 44 is placed on the upper side of the bottom wall of the lower shell 8. Through the installation and cooperation of the lower mounting ear 44 and the lower shell 8, the bottom of the front cover assembly 4 is fastened to the lower shell 8.

[0032] Specifically, the upper mounting ear 43 and the lower mounting ear 44 are both provided with a fourth through hole 45. The bottom wall of the outer shell support plate 9 and the lower shell 8 are provided with a connecting through hole 93 and a connecting through hole 81 corresponding to the fourth through hole 45. The front cover assembly 4 is fastened to the outer shell support plate 9 and the lower shell 8 by screws passing through the fourth through hole 45 and the connecting through hole 93 or the connecting through hole 81 from top to bottom.

[0033] This structure can fix the front cover assembly 4 between the lower housing 8 and the outer shell support plate 9, and also transfer the force borne by the front side of the outer shell support plate 9 to the bottom wall of the lower housing 8 through the front cover assembly 4, thereby reducing the force on the side wall of the lower housing 8 and helping to prevent the side wall of the lower housing 8 from deforming and shrinking.

[0034] The pot assembly 2 includes an outer pot 21 and an inner pot 22. The opening of the outer pot 21 is mounted on the upper shell 7 and fits into the hollow cavity 901. A heating plate 23 is provided at the bottom of the outer pot 21. The inner pot 22 is detachably embedded in the outer pot 21 and rests against the upper side of the heating plate 23. The inner pot 22 and the top cover 3 together define a steam generating chamber 5.

[0035] Several zigzag brackets 12 are provided on the outer periphery of the outer pot 21. The upper connecting part 121 of the bracket 12 is fastened to the bottom of the outer shell support plate 9, and the lower connecting part 122 of the bracket 12 is fastened to the bottom of the outer pot 21. Both the upper connecting part 121 and the lower connecting part 122 are provided with a fifth through hole 123. The outer shell support plate 9 and the outer pot 21 are provided with a connecting blind hole 95 corresponding to the fifth through hole 123. By passing screws from bottom to top through the fifth through hole 123 and the connecting blind hole 95, the two ends of the bracket 12 are respectively fastened to the outer shell support plate 9 and the outer pot 21.

[0036] In this embodiment, since the inner pot 22 is deep, it can hold a large amount of water during use, which results in a large weight of the entire pot assembly 2. Therefore, the pressure at the connection between the outer pot 21 and the upper shell 7 is large, which can easily cause structural damage. However, by using the bracket 12 connected to the outer shell support plate 9 to support the outer pot 21, some of the weight can be distributed to the lower shell 8, thereby reducing the pressure on the upper shell 7.

[0037] In addition, the lower connecting part 122 has an integrally bent anti-rotation folding lug 124 at a position further forward of the fifth through hole 123, and the bottom of the outer pot 21 has a corresponding folding inlet 211. Through the cooperation of the anti-rotation folding lug 124 and the folding inlet 211, the bracket 12 can be prevented from twisting due to stress, and the stability is better.

[0038] The outer shell support plate 9 is provided with a first anti-foolproof part on the left and right sides, and the lower shell 8 is provided with a first anti-foolproof mating part on the inner wall surface corresponding to the first anti-foolproof part; The rear side of the outer shell support plate 9 is provided with a second anti-foolproof part, and the inner wall surface of the lower shell 8 corresponding to the second anti-foolproof part is provided with a second anti-foolproof mating part.

[0039] This structure, through the cooperation of two types of foolproof parts and foolproof mating parts, enables the outer shell support plate 9 to be oriented and installed at the joint between the upper shell 7 and the lower shell 8, preventing the outer shell support plate 9 from being rotated back and forth during assembly, thereby improving production efficiency.

[0040] The specific implementation method is as follows: the first and second anti-mistake mating parts are also anti-mistake ribs 82. The anti-mistake ribs 82 extend along the height direction. However, the first anti-mistake mating part includes three anti-mistake ribs 82 that are spaced apart from each other, while the second anti-mistake mating part includes one anti-mistake rib 82. The one anti-mistake rib 82 is located in the middle of the inner wall surface. The first and second anti-mistake parts include anti-mistake grooves 94 with different numbers corresponding to the anti-mistake ribs 82. The anti-mistake grooves 94 are provided in the lower half of the outer shell support plate and have a limiting groove surface 941 that limits the abutment against the top surface of the anti-mistake ribs 82. When the number of anti-mistake grooves 94 does not correspond to the number of anti-mistake ribs 82, the outer shell support plate 9 cannot be placed into the lower shell 8, which means that the assembly position of the outer shell support plate 9 is incorrect, and the assembly personnel can quickly adjust it. The cooperation between the anti-foolproof rib 82 and the limiting groove surface 941 allows the outer shell support plate 9 to be placed on the lower shell 8 without any fastening connection structure, thus serving as a support and positioning function.

[0041] Second embodiment: In the second embodiment, as Figure 7 As shown: In the original structure, the outer shell support plate 9 has several longitudinal ribs 96 integrally connected to its four sides. The longitudinal ribs 96 are closely attached to the inner wall surfaces of the upper shell 7 and the lower shell 8. This embodiment mainly uses multiple longitudinal ribs 96 to support different positions of the inner wall surfaces of the upper shell 7 and the lower shell 8 to prevent deformation and shrinkage of the upper shell 7 and the lower shell 8.

[0042] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
