Detailed Description

The utility model is described in further detail below with reference to the accompanying examples.

As shown in fig. 1 to 5, a preferred embodiment of the present invention. In this embodiment, this a filter core mounting structure for water purifier includes casing 1, filter core 3, limit structure and elastic component 5, and wherein casing 1 is the tube-shape, and its inside cavity forms the installation passageway 10 that is used for holding filter core 3, and is equipped with water route board 2 on this casing 1, has seted up water inlet 2a, pure water export 2b and dense water export 2c on water route board 2. In installation passageway 10 is then located to filter core 3, filter core 3 in this embodiment can realize dismantling from the direction of difference, and it is convenient from the upper end dismouting, consequently has the uncovered that supplies filter core 3 to insert in installation passageway 10 in the upper end of casing 1, and the bottom of casing 1 is then located to water route board 2.

The installation and the detachment of the filter element 3 and the shell 1 are realized through the limiting structure. The limiting structure in this embodiment includes the guide groove 40 and the guide post 31 which are slidably fitted to each other, and the positions of the guide groove 40 and the guide post 31 can be flexibly designed, for example, the guide groove 40 can be opened on one of the inner wall of the housing 1 and the outer wall of the filter element 3, and the guide post 31 is opened on the other one of the inner wall of the housing 1 and the outer wall of the filter element 3. In this embodiment, the side plate 4 is installed on the outer wall of the housing 1, the guide groove 40 is opened on the side plate 4, the guide post 31 is protruded on the outer wall of the filter element 3, and the peripheral wall of the housing 1 is provided with an avoiding opening at a corresponding position for the guide post 31 to penetrate out, so that the side plate 4 is independently installed, and when a foreign object appears in the guide groove 40, the foreign object can be timely detached and disposed.

The guide slot 40 can have different forms, in this embodiment, the above-mentioned side plate 4 is recessed inwards on the side wall adjacent to the casing 1 to form a ring-shaped blocking wall 41, the middle of the blocking wall 41 is convexly provided with a boss 42, the guide slot 40 formed by spacing the outer edge of the boss 42 and the inner edge of the blocking wall 41 is left between, that is, the whole guide slot 40 is designed in a ring shape, and has a first guide section 401 and a second guide section 402 which are oppositely arranged and vertically extend, besides, in order to form a closed ring-shaped structure, the part of the second guide section 402 adjacent to the upper end is inclined towards the first guide section 401 and is connected with the upper end of the first guide section 401, a connecting section 403 is arranged between the first guide section 401 and the second guide section 402, two ends of the connecting section 403 are respectively connected with the lower ends of the first guide section 401 and the second guide section 402 so as to enclose and form a complete guide slot 40, so that under the action of the guide slot 40, the guide post 31, which enters the guide groove 40 from the first guide section 401 or the second guide section 402, slides up and down in response to the cartridge 3 moving up and down with respect to the installation passage 10, i.e., in response to both the removal and installation of the cartridge 3.

Naturally, in order to ensure that the guide groove 40 also acts as a stop for the filter insert 3 in the installed state, the guide groove 40 is further provided with a stop 4030 on the sliding path of the guide post 31, wherein the stop 4030 is arranged between the first guide section 401 and the second guide section 402 as a whole, and since the first guide section 401 and the second guide section 402 have the connecting section 403, the stop 4030 in this embodiment is formed on the connecting section 403. Of course, there are various structures for realizing the limit, and this embodiment adopts a limit form in which the concave portions 4031 and the convex portions 4032 are arranged in a staggered manner, that is, the concave portions 4031 having a local upward concavity on the lower edge of the boss 42 correspond to the convex portions 4032 having an upward convexity on the lower edge of the barrier wall 41, and the concave portions 4031 and the convex portions 4032 are arranged in a staggered manner. In the design form of the limit portion 4030, the sliding process of the guide column 31 in the whole guide groove 40 is continuous, and only a slight external force needs to be applied, so that the guide column 31 can slide from the part where the first guide section 401 is engaged with the convex portion 4032 to between the convex portion 4032 and the concave portion 4031, and is finally limited at the concave part of the concave portion 4031, and the locking of the filter element 3 is realized; when the external force is applied again, the guiding column 31 moves along the inclined surface of the lower section of the recess 4031 and is released from the recess 4031, and then slides into the second guiding section 402 again along the joint of the recess 4031 and the second guiding section 402. Because the guide groove 40 is annular, the guide column 31 can be switched between the locking state and the unlocking state easily by means of the limiting effect of the limiting part 4030 on the guide column in such a circulating reciprocating manner, and the locking mechanism is very convenient and fast. Namely, in the state that the guide column 31 is limited on the limit part 4030, the filter element 3 is installed in the installation channel 10, and the filter element 3 is in fluid communication with the water outlet end of the water channel plate 2; in a state where the guide post 31 is disengaged from the stopper 4030, the filter element 3 is removed from the installation passage 10.

Furthermore, since the ejection of the filter cartridge 3 requires a certain external force for support, the above-mentioned elastic element 5 plays a certain supporting role, and the elastic element 5 acts on the filter cartridge 3 and always has a tendency to detach the filter cartridge 3 from the installation channel 10. Specifically, the waterway plate 2 is provided with a mounting hole 20 having an upward opening, a push rod 21 vertically movable with respect to the mounting hole 20 is provided in the mounting hole 20, and the elastic member 5 acts on the filter element 3 via the push rod 21. The bottom of the push rod 21 is provided with a limiting hole 22, one end of the elastic element 5 is abutted against the limiting hole 22, and the other end is abutted against the inner wall of the mounting hole 20. In addition, the water inlet 2a, the purified water outlet 2b and the concentrated water outlet 2c are arranged in a straight line shape and divide the water circuit board 2 into two mounting areas, a mounting hole 20 is formed in each mounting area, and an elastic part 5 is arranged in each mounting hole 20.

The term "fluid communication" as used herein refers to a spatial relationship between two components or portions (hereinafter collectively referred to as a first portion and a second portion, respectively), i.e., a fluid (gas, liquid or a mixture of both) can flow along a flow path from the first portion and/or be transported to the second portion, and may be a direct communication between the first portion and the second portion, or an indirect communication between the first portion and the second portion via at least one third element, such as a fluid channel, e.g., a pipe, a channel, a duct, a flow guide, a hole, a groove, or a chamber that allows a fluid to flow through, or a combination thereof.

Also, directional terms, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," "bottom," and the like, may be used in the description and claims to describe various example structural portions and elements of the utility model, but are used herein for convenience of description only and are determined based on the example orientations shown in the figures. Because the disclosed embodiments of the present invention may be oriented in different directions, the directional terms are used for descriptive purposes and are not to be construed as limiting, e.g., "upper" and "lower" are not necessarily limited to directions opposite to or coincident with the direction of gravity.
