Technical Field

[0001] The utility model relates to a water purifier. Background Art

[0002] A water purifier, also called a water purifier or water purifier, is a water treatment device that deeply filters and purifies water according to the requirements for water use. A household water purifier generally includes a housing and a filter waterway set inside the housing. There are also many existing water purifiers that have added functions such as electric water pumps, ultraviolet sterilization, and filter element replacement reminders. Such water purifiers require a control circuit. At present, the control circuit and filter waterway of such water purifiers are set in the same chamber. Once the filter waterway has problems such as water leakage, it will affect the electrical safety of the control circuit and increase safety hazards. Utility Model Content

[0005] The outer periphery of the middle cover plate forms an upwardly protruding middle connecting strip, and the outer periphery of the upper cover plate forms a downwardly protruding upper connecting strip. Both the upper connecting strip and the middle connecting strip are annular. The upper connecting strip is sleeved outside the middle connecting strip, and the middle connecting strip is connected to the upper connecting strip.

[0006] The middle connecting bar is detachably connected to the upper connecting bar via a first threaded fastener.

[0007] The outer wall of the middle connecting strip is raised to form a tight-fitting rib, and the tight-fitting rib is tightly fitted with the inner wall of the upper connecting strip.

DETAILED DESCRIPTION

[0023] 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.

[0024] 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.

[0025] 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.

[0026] A water purifier, such as Figure 1-3 As shown, it includes a main housing 100, a middle cover plate 200, and an upper cover plate 300 connected in sequence from bottom to top, a waterway cavity A for accommodating a filtered waterway is formed between the main housing 100 and the middle cover plate 200, and a circuit cavity B for accommodating a control module is formed between the middle cover plate 200 and the upper cover plate 300. In this way, the circuit cavity B is arranged above the waterway cavity A and is separated by the middle cover plate 200. When the filtered waterway in the waterway cavity A leaks, it will not affect the control module located in the circuit cavity B, which is safer and has a longer service life.

[0027] like Figure 4 As shown, the outer periphery of the middle cover plate 200 is formed with a middle connecting strip 210 protruding upwards. Figure 5 As shown, the outer periphery of the upper cover plate 300 forms an upper connecting strip 310 protruding downward, and the upper connecting strip 310 and the middle connecting strip 210 are both annular. Figure 6 As shown, the upper connecting bar 310 is sleeved outside the middle connecting bar 210 , and the middle connecting bar 210 is connected to the upper connecting bar 310 .

[0028] Furthermore, the middle connecting bar 210 and the upper connecting bar 310 are detachably connected via a first threaded fastener.

[0029] Specifically, the outer wall of the middle connecting strip 210 is raised to form a tight-fitting rib 211, and the tight-fitting rib 211 is tightly fitted with the inner wall of the upper connecting strip 310. The provision of the tight-fitting rib 211 can partially replace the first threaded fasteners, that is, the number of first threaded fasteners can be reduced, thereby reducing the number of first threaded fasteners that need to be rotated during disassembly and assembly, thereby improving disassembly and assembly efficiency.

[0030] Furthermore, the upper connecting bar 310 and the middle connecting bar 210 are both in the shape of a square ring, and the angles formed by the edges of the upper connecting bar 310 and the middle connecting bar 210 are rounded transitions. The tight-fitting ribs 211 are distributed on the four sides of the middle connecting bar 210, and the first connecting hole 212 is only provided on one side of the middle connecting bar 210. The second connecting hole 311 is provided on the corresponding side of the upper connecting bar 310, and the first threaded fastener passes through the first connecting hole 212 and the second connecting hole 311 to connect the middle connecting bar 210 and the upper connecting bar 310. The four sides of the upper connecting bar 310 and the middle connecting bar 210 are all tightly fitted by the tight-fitting ribs 211, and the first threaded fastener is only provided on one side. In this way, when the first threaded fastener is disassembled and assembled, it is sufficient to operate on the side without moving it. The number of tight-fitting ribs 211 provided is related to the length of the corresponding side, and the spacing between adjacent tight-fitting ribs 211 needs to be appropriate so that the two are stably connected. After the first threaded fastener is removed, the upper connecting bar 310 and the middle connecting bar 210 can be tightly matched or separated by a certain external force, which is easy to operate. The corners formed by the edges of the upper connecting bar 310 and the middle connecting bar 210 are rounded transitions.

[0031] like Figure 2 As shown, a lower connecting strip 110 with a certain width is formed at the upper end of the main housing 100, and the middle cover plate 200 is connected to the lower connecting strip 110 through its bottom and then connected to the main housing 100; the outer peripheral shape of the upper connecting strip 310 is adapted to the outer peripheral shape of the main housing 100. The structure is compact and the appearance is consistent, and the setting of the middle cover plate 200 cannot be seen from the outside, which is more concise and beautiful.

[0032] The middle cover plate 200 is directly connected to the lower connecting bar 110 via a second threaded fastener.

[0033] like Figure 2 As shown, the circuit cavity B is provided with a controller housing 400, the control module is installed in the controller housing 400, and the controller housing 400 is provided with a through hole for threading. In this way, the control module can be well protected and the wires are neatly routed. The wires connecting the control module and the related electrical devices on the filtration waterway in the waterway cavity A need to pass through the middle cover plate 200.

[0034] The controller housing 400 is mounted on the middle cover plate 200 by means of a third threaded fastener.

[0035] 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.
