[0036] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0037] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0038] The directions and positions mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are only for reference to the directions or positions of the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0039] A body structure of a water purifier, such as Figure 1 As shown, it includes a main housing 100 and a door panel 200 detachably disposed on the main housing. Specifically, as shown Figure 2 As shown, the main housing 100 is provided with a door opening 110 adapted to the door panel 200, and the door panel 200 is arranged in the door opening 110; the door panel 200 is provided with a movable latch 210, and the inner peripheral wall of the door opening 110 is provided with a slot 111 corresponding to the movable latch 210, and the movable latch 210 is movable relative to the door panel 200 and has a locking position where the protrusion relative to the outer periphery of the door panel 200 is inserted into the slot 111 and an unlocking position where the movable latch 210 is retracted and leaves the slot 111. The "adaptation" between the door panel 200 and the door opening 110 means that the shapes of the door panel 200 and the door opening 110 are roughly the same, so that after the door panel 200 is installed in the door opening 110, an integral housing structure is formed in appearance, and it does not need to be perfectly fitted, and a certain gap is allowed to form between the door panel 200 and the door opening 110 to facilitate the installation of the door panel 200.

[0040] The main housing 100 is formed by connecting a plurality of plates to form a whole. Figure 3 As shown, specifically, the main shell 100 includes a bottom plate 120 , two side plates 130 , and an upper cover 140 . The bottom plate 120 , the two side plates 130 , and the upper cover 140 are connected to form a door opening 110 .

[0041] Specifically, two movable latches 210 are provided, and the two movable latches 210 are respectively located on both sides of the door panel 200. Alternatively, one movable latch 210 may be provided, but the stability is relatively poor; alternatively, multiple movable latches 210 may be provided, that is, three or more, but the disassembly and assembly operation will be more troublesome.

[0042] Further, such as Figure 4-8 As shown, the inner side of the door panel 200 is provided with a hook portion 220 that is raised and extends in one direction to form a hook-shaped structure, and the inner periphery of the door opening 110 forms a first clamping portion 112 corresponding to the hook portion 220. By installing the door panel 100 into the door opening 110 in one direction, the hook portion 220 and the first clamping portion 112 can form a clamping limit fit. During installation, the movable latch 210 on the door panel 100 is first operated to make it an unlocked position, and then the door panel 100 is installed into the door opening 110 in one direction so that the hook portion 220 and the first clamping portion 112 form a clamping limit fit, and finally the movable latch 210 on the door panel 100 is operated to make it a locked position. In this way, the clamping limit fit structure formed by the hook portion 220 and the first clamping portion 112 and the two movable latches 210 can form at least three fixed connection points of the door panel 100, and the fixation is more stable.

[0043] Furthermore, the hook portion 220 extends in the first direction X to form a hook-shaped structure, and the movable latch 210 in the locked position protrudes in the second direction Y relative to the door panel 200, and the second direction Y is perpendicular to the first direction X. This arrangement is more stable.

[0044] Further, such as Figure 4 , Figure 5 As shown, the two ends of the door panel 200 in the first direction X are respectively a first end and a second end, and the hook portion 220 is disposed close to the first end of the door panel 200;

[0045] The two movable latches 210 are respectively located on two end sides of the door panel 200 in the second direction Y and are disposed away from the first end of the door panel 200 .

[0046] Further, such as Figure 6 As shown in (b), the hook portion 220 is a plate-like structure protruding inward from the inner wall of the door panel 200, and a slot 221 with an opening toward the first end is formed between the hook portion 220 and the inner wall of the door panel 200. Figure 7 , Figure 8 As shown, the first clamping portion 112 is a plate-like structure that vertically protrudes inward from the inner circumference corresponding to the side edge of the door opening 110 . The first clamping portion 112 is inserted into the clamping groove 221 so that the hook portion 220 and the first clamping portion 112 form a clamping and limiting fit.

[0047] like Figure 6 As shown in (b), the hook portion 220 is provided with an inclined guide surface 222 on the inner side edge close to the inner wall of the door panel 200. This arrangement facilitates the hook portion 220 and the first clamping portion 112 to form a clamping and limiting fit during installation.

[0048] Specifically, Figure 5-6 As shown, the door panel 200 is a three-dimensional plate structure with a certain thickness formed by integrally bending a metal sheet, and includes a first outer plate body 230, a first circumferential plate body 240, a first inner side edge plate body 250, and a first inner bottom side plate body 260. The first circumferential plate body 240 is connected to the outer periphery of the first outer plate body 230, the first inner side edge plate body 250 is connected to the side of the first circumferential plate body 240 located on both sides away from the first outer plate body 230, and the first inner bottom side plate body 260 is connected to the side of the first circumferential plate body 240 located on the bottom side away from the first outer plate body 230; the first inner side edge plate body 250 is provided with two first inner side edge plates 250 and a certain interval is spaced between the two first inner side edge plates 250, the hook portion 220 is connected to the first inner side edge plate body 250 as a whole; the first inner bottom side plate body 260 constitutes the inner wall of the door panel 200 that forms a slot 221 with the hook portion 220. Such an arrangement can reduce production costs and improve the overall strength of the door panel 200. It can also weld the connections between the first outer plate 230, the first circumferential plate 240, the first inner edge plate 250 and the hook portion 220. However, the strength of the welds is relatively poor and the production cost is high.

[0049] The movable latch 210 is installed in the cavity formed among the first outer plate 230, the first circumferential plate 240 and the first inner edge plate 250. The first outer plate 230 is formed with an operating port 231 for pushing the movable latch 210, and the first circumferential plates 240 on both sides are formed with through grooves 241 for the movable latch 210.

[0050] like Figure 7 , Figure 8 As shown, the bottom plate 120 is a three-dimensional plate structure with a certain thickness formed integrally by a metal sheet, and the first clamping portion 112 is integrally formed on the bottom plate 120. Specifically, the bottom plate 120 includes a third outer plate body 121, a third circumferential plate body 122, a third inner plate body 123, and a third connecting plate 124. The third outer plate body 121 is located at the bottom, and the third circumferential plate body 122 is formed by bending or stamping the third outer plate body 121 circumferentially upward. The third inner plate body 123 is a strip plate body with a smaller width formed by bending the upper end of the third circumferential plate body 122 inwardly, and the third connecting plate 124 is a strip plate body with a smaller width formed by bending the inner end of the third inner plate body 123 upwardly, and the first clamping portion 112 is the portion of the third connecting plate 124 corresponding to the hook portion 220.

[0051] The side plate 130 is a three-dimensional plate structure with a certain thickness formed by a metal sheet. Fig. 9 , Fig.10 As shown, the side plate 130 includes a second outer plate body 131, a second inner plate body 132, a second circumferential plate body 133, and a second connecting plate 134. The second outer plate body 131 is located on the outer wall of the body, the second circumferential plate body 133 is formed by circumferential bending or stamping of the second outer plate body 131, the second inner plate body 132 is a strip plate body with a smaller width formed by inward bending of the inner end of the second circumferential plate body 133, the second connecting plate 134 is a strip plate body with a smaller width formed by vertically bending the inner end of the third inner plate body 123, a cavity is formed between the second outer plate body 131 and the second inner plate body 132, and the slot 111 is a slot formed on the second inner plate body 132.

[0052] Through holes are formed on the second connecting plate 134 and the third connecting plate 124 for being connected and fastened to each other by bolts to form the main housing 100 .

[0053] The movable latch 210 is equipped with a return spring (not shown in the figure). Under the action of the return spring, the movable latch 210 maintains the locked position, that is, the movable latch 210 maintains the locked position without the action of external force. When unlocking is required, a certain external force can be applied to the movable latch 210.

[0054] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
