DETAILED DESCRIPTION

[0017] Preferred embodiments of the present application will be described in greater detail below, with reference to the accompanying drawings. While preferred embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0018] The term "comprising" and variations thereof as used herein are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements is not necessarily limited to those elements, but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Unless otherwise specified, the term "or" as used herein is intended to mean "and / or". The term "based on" means "based, at least in part, on". The terms "one example embodiment" and "an embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "a first", "a second", etc. can refer to different or the same objects.

[0019] As shown in Figures 1-4 The embodiment of the present application provides a combined water purifier composite filter element, which comprises a butt block 1, referring to Figure 2 Two I-shaped clamping blocks 11 are arranged at the right end of the butt block 1, and two clamping grooves 12 matched with the clamping blocks 11 are arranged at the left end of the butt block 1. When the two adjacent clamping grooves 12 are butted, the clamping block 11 needs to be clamped into the clamping groove 12 from top to bottom, so that the connection between the butt blocks 1 can be realized. The number of the butt blocks 1 can be selected according to the user's own needs. A U-shaped limiting frame 4 is slidably arranged on the left part of the upper surface of the butt block 1, and a spring is arranged between the limiting frame 4 and the butt block 1. The two ends of the limiting frame 4 correspond to the two clamping grooves 12 on the butt block 1, respectively. An inclined block 41 is fixedly arranged at each end of the limiting frame 4, and the inclined block 41 is located directly above the clamping groove 12. When the clamping block 11 is clamped into the clamping groove 12 from top to bottom, it can slide into the clamping groove 12 along the inclined surface, so that the efficiency of butt joint is improved. During the process of sliding down of the clamping block 11, the limiting frame 4 will slide right as a whole. After the butt joint of the clamping block 11 and the clamping groove 12 is completed, the limiting frame 4 will be bounced back. Then, under the block of the flat bottom of the inclined block 41, the clamping block 11 cannot be separated from the clamping groove 12, so as to ensure the stability of the connection.

[0020] As shown in Figure 3 In the embodiment of the present application, a clamping column 13 arranged at the bottom of the butt block 1 and a filter tank 2 matched with the clamping column 13 are further included. When the filter tank 2 is installed, the filter tank 2 needs to be sleeved on the clamping column 13. Different filter tanks 2 use different filter elements inside. The user can freely select and combine different filter tanks 2 according to the actual filtering needs, so as to realize the personalized filtering scheme. Referring to Figure 3A pair of clamping hooks 32 are symmetrically arranged in the docking block 1 and slide in the docking block 1, pressure springs 33 are arranged between the two clamping hooks 32 and the docking block 1, after the filter tank 2 is sleeved on the clamping column 13, the clamping hooks 32 are tightly attached to the filter tank 2 under the action of the pressure springs 33, the clamping of the filter tank 2 is completed, and the hook-shaped part of the clamping hook 32 also hooks the filter tank 2 to prevent the filter tank 2 from falling. A rotating disc 31 is further arranged in the docking block 1, two inclined holes 311 are arranged on the upper surface of the rotating disc 31, the top ends of the two clamping hooks 32 are respectively clamped into different inclined holes 311, and a knob 3 is further arranged on the upper surface of the docking block 1 and is fixedly connected with the rotating disc 31, and the knob 3 penetrates the docking block 1. By rotating the knob 3 clockwise, the two clamping hooks 32 can be away from each other, the filter tank 2 is no longer clamped, and the filter tank 2 can be easily removed.

[0021] As shown in Figure 2 and Figure 4 , the arc plates 5 are fixedly arranged on the front and rear sidewalls of the docking block 1, clamping frames 51 are slidably arranged on the arc plates 5, and springs are arranged between the clamping frames 51 and the arc plates 5. After the entire composite filter element is assembled, the composite filter element can be clamped and fixed on the water purifier or other positions by cooperation of the springs and the clamping frames 51. Referring to Figure 4 , the mounting plates 6 are fixedly arranged at the ends of the clamping frames 51, a pair of clamping shafts 61 are arranged on the mounting plates 6, and referring to Figure 4 , the hook plates 62 are rotatably arranged on the clamping shaft 61 on the right side, and the right end of the hook plate 62 is buckled to the clamping shaft 61 on the left side of the adjacent mounting plate 6, so that the series connection of all the mounting plates 6 and the clamping frames 51 is realized. When the composite filter element is subsequently removed from the water purifier, any one of the hook plates 62 can be pulled to simultaneously pull away all the mounting plates 6 and the clamping frames 51, so that the composite filter element can be quickly removed.
