DETAILED DESCRIPTION

[0016] The utility model is described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 1 and 2 As shown, this embodiment discloses a secondary water supply device, including a box body, wherein a baffle 1 is provided inside the box body, wherein the baffle 1 divides the box body into a static chamber 2 and a water storage chamber 3, and wherein the water outlet 4 of the water storage chamber 3 is detachably connected with a filter tube 5, wherein the outer peripheral wall of the water inlet of the filter tube 5 is provided with a snap assembly, wherein the outer peripheral wall of the water outlet 4 of the water storage chamber 3 is provided with a snap assembly 6 that is movably matched with the snap assembly, and wherein a filter layer is provided inside the filter tube 5. The snap assembly can be symmetrically arranged on both sides of the outer peripheral wall of the filter tube 5, and the number of the snap assemblies 6 is also two, and the snap assembly and the snap assemblies 6 are arranged in a one-to-one corresponding manner. When the filter layer needs to be cleaned or replaced, the snap assembly is separated from the snap assemblies 6, the filter tube 5 is removed, and the filter layer in the filter tube 5 is cleaned or reinstalled and then installed together with the water storage chamber 3, and the water in the water storage chamber 3 is filtered again. The filter tube 5 can also be connected to the lower water connecting pipe (the filter tube 5 is arranged between the water storage chamber 3 and the lower water connecting pipe) through a clamping assembly, and a corresponding clamping protrusion 6 is also provided on the lower water connecting pipe.

[0018] In this embodiment, if Figure 1As shown, the clamping assembly includes a trigger 7 and a hook 8, one end of the trigger 7 is rotatably connected to the filter tube 5, and the other end of the trigger 7 is connected to the hook 8, and the hook 8 is provided with a bending portion 9 that movably cooperates with the clamping protrusion 6. The trigger 7 includes a connecting portion 10 and a pressing portion 11 integrally connected to the connecting portion 10, the connecting portion 10 is connected to the filter tube 5 through a rotating shaft, and the hook 8 is rotatably provided at one end of the connecting portion 10 close to the pressing portion 11. By pulling the pressing part 11 upward, the pressing part 11 drives the hook 8 to move, shortening the distance between the hook 8 and the water outlet 4 of the water storage chamber 3, separating the bent part 9 of the hook 8 from the convex 6, rotating the bent part 9 upward, and then removing the filter tube 5. After replacing the filter layer in the filter tube 5, the pressing part 11 is pressed downward. As the distance between the hook 8 and the water outlet 4 of the water storage chamber 3 increases, the bent part 9 and the convex 6 abut against each other, fixing the passing pipe on the water outlet 4 of the water storage chamber 3.

[0019] In this embodiment, if Figure 2 As shown, the side of the clamping protrusion 6 away from the trigger 7 is provided with a groove 12 that cooperates with the bending portion 9. The groove 12 limits the bending portion 9 to prevent the clamping hook 8 from being displaced.

[0020] In this embodiment, if Figure 2 As shown, the filter tube 5 is provided with a protrusion 16, and one end of the connecting portion 10 away from the pressing portion 11 is rotatably connected to the protrusion 16. A rotating shaft is provided in the protrusion 16, and the connecting portion 10 is rotatably connected to the rotating shaft, which is the prior art.

[0021] In this embodiment, if Figure 1 As shown, the height of the baffle 1 is less than the height of the box body, and the height of the baffle 1 is not less than half of the height of the box body. The baffle 1 and the top surface of the box body have a channel for clean water to flow through, and large particles of debris are deposited at the bottom of the static chamber 2. The clean water after static enters the water storage chamber 3 through the channel. The height of the baffle 1 is set to ensure that the silt deposited below does not enter the water storage chamber 3.

[0022] In this embodiment, if Figure 1 As shown, the filter layer includes a first filter layer 13, a second filter layer 14 and a third filter layer 15 arranged in sequence. The first filter layer 13 is a sand filter layer, the second filter layer 14 is an activated carbon filter layer, and the third filter layer 15 is a silver ion activated carbon filter layer. The first filter layer 13 is closest to the water outlet 4 of the water storage chamber 3.

[0023] The above description is only a preferred embodiment of the utility model, and does not limit the patent protection scope of the utility model. Any equivalent structural transformation made using the contents of the utility model specification and drawings, directly or indirectly used in other related technical fields, is also included in the protection scope of the utility model.
