[0035] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0036] Next, with reference to Figures 1 - 9 , the pre-filter 100 according to the embodiments of the present invention will be described. The pre-filter 100 includes a filter bottle 10 and filter media 20 disposed inside the filter bottle 10. Among them, the filter media 20 can be PP cotton, carbon rod, etc.

[0037] Specifically, the filter bottle 10 defines a filter cavity 11, and the filter media 20 is disposed inside the filter cavity 11. The filter media 20 divides the filter cavity 11 into a water inlet channel 31 and a water outlet channel 32. That is to say, tap water enters the water inlet channel 31 of the filter cavity 11, and after being filtered by the filter media 20, it flows out from the water outlet channel 32. It can be understood that the water filtered by the pre-filter 100 can be further filtered by a reverse osmosis filter and a post-filter in sequence to obtain clean water.

[0038] The filter bottle 10 is integrally formed with a first water pipe 12 and a second water pipe 13. Among them, the water inlet channel 31 is communicated with the first water pipe 12, and the water outlet channel 32 is communicated with the second water pipe 13. That is, the water to be filtered is introduced into the water inlet channel 31 of the pre-filter element 100 through the first water pipe 12, and the filtered water in the water outlet channel 32 is led out through the second water pipe 13.

[0039] In other words, the first water pipe 12 on the filter bottle 10 is connected to the water source, and the water to be filtered is introduced into the filter cavity 11 of the pre-filter element 100. The second water pipe 13 leads out the water in the filter cavity 11. That is, through the first water pipe 12 and the second water pipe 13, the inlet and outlet water paths of the pre-filter element 100 can be clearly distinguished, so that the water path direction of the pre-filter element 100 is clear at a glance for users or installers, and it is convenient for installation and maintenance. In addition, since the inlet and outlet water paths are converted through the first water pipe 12 and the second water pipe 13, the number of water path conversion joints used is reduced.

[0040] Therefore, for the pre-filter element 100 according to the embodiment of the present invention, by integrally forming the first water pipe 12 and the second water pipe 13 on the filter bottle 10, it is convenient to convert the inlet and outlet water paths of the pre-filter element 100 through the first water pipe 12 and the second water pipe 13, making the water path connection clearer, not easy to make mistakes, reducing the use of water path conversion joints, and reducing the manufacturing cost.

[0041] In an alternative embodiment, as Figure 1 、 Figure 2 and Figure 8 shown, the filter bottle 10 is further integrally formed with a third water pipe 14, and the third water pipe 14 is communicated with the second water pipe 13. That is, the filtered water in the second water pipe 13 is received through the third water pipe 14. Among them, through the third water pipe 14, water can be supplied to the next-stage filter element or directly supplied as domestic water externally.

[0042] In a further alternative embodiment, as Figure 3 combined with Figure 4 and Figure 8 shown, the second water pipe 13 includes a first outlet 131 and a second outlet 132. One of the first outlet 131 and the second outlet 132 is communicated with the third water pipe 14, and the other directly supplies domestic water externally. That is, the water in the second water pipe 13 can flow out in two directions. Part of the water is continuously supplied to the third water pipe 14, and the other part of the water is directly sent out externally. That is to say, by forming the second water pipe 13 and the third water pipe 14 on the filter bottle 10, the filtered water of the pre-filter element 100 is transported in different directions, and water for various uses is obtained.

[0043] In an alternative example, a water inlet solenoid valve 40 is provided between the inlet of the second water passing pipe 13 and the inlet of the third water passing pipe 14. That is, the on-off of the second water passing pipe 13 and the third water passing pipe 14 is controlled by the water inlet solenoid valve 40. Among them, the inlet of the water inlet solenoid valve 40 is communicated with one of the outlets of the second water passing pipe 13, and the outlet of the water inlet solenoid valve 40 is communicated with the inlet of the third water passing pipe 14. To facilitate the connection of the water inlet solenoid valve 40 with the second water passing pipe 13 and the third water passing pipe 14, the water inlet solenoid valve 40 can be fixed to the filter bottle 10. For example, as Figure 2 and Figure 8 shown, the filter bottle 10 is provided with positioning posts having screw holes. In this way, the water inlet solenoid valve 40 can be locked to the filter bottle 10 by screws.

[0044] In an alternative embodiment, as Figure 1 and Figure 2 shown, the first water passing pipe 12, the second water passing pipe 13 and the third water passing pipe 14 are formed at the bottom of the filter bottle 10, and the second water passing pipe 13 is located between the first water passing pipe 12 and the third water passing pipe 14. In this way, water flow can be introduced into the outside of the filter cavity 11 (water inlet channel 31) through the first water passing pipe 12, and after being filtered by the filter medium 20, it flows into the inside of the filter cavity 11 (water outlet channel 32). In other words, the water flow penetrates from the outside to the inside, and the water outlet channel 32 is formed in the middle of the filter cavity 11. By reasonably arranging the positions of the first water passing pipe 12, the second water passing pipe 13 and the third water passing pipe 14, it is convenient for the first water passing pipe 12 and the second water passing pipe 13 to be respectively communicated with the water inlet channel 31 and the water outlet channel 32.

[0045] In an alternative example, as Figure 4 、 Figure 5 and Figure 8 shown, one side of the filter bottle 10 is recessed inward to form a first notch 15, and the other side is recessed inward to form a second notch 16. The first water passing pipe 12, the second water passing pipe 13 and the third water passing pipe 14 extend from one side of the filter bottle 10 to the other side. Specifically, one ends of the first water passing pipe 12, the second water passing pipe 13 and the third water passing pipe 14 are located in the first notch 15, and the other ends of the second water passing pipe 13 and the third water passing pipe 14 are located in the second notch 16. In this way, it is convenient for the first water passing pipe 12, the second water passing pipe 13 and the third water passing pipe 14 to be connected to the PE pipe, further improving the convenience of the pipeline connection of the pre-filter element 100.

[0046] In a specific embodiment of the present invention, sheaths 17 are respectively formed at the ends of the first water pipe 12, the second water pipe 13 and the third water pipe 14, and the sheaths 17 are spaced apart from the outer walls of the first water pipe 12, the second water pipe 13 and the third water pipe 14. The sheath 17 can separate the ends of the first water pipe 12, the second water pipe 13 and the third water pipe 14 from other components, avoiding the first water pipe 12, the second water pipe 13 and the third water pipe 14 from being knocked and broken by other hard objects during use, which affects the normal connection of the pipeline.

[0047] Furthermore, each of the sheaths 17 forms an opening 171 that opens downward. This opening 171 is conducive to the disassembly and assembly of the pipeline and the first water pipe 12, the second water pipe 13 and the third water pipe 14.

[0048] In an alternative embodiment, the filter bottle 10 includes a bottle body 18 and a bottle cap 19, and the bottle body 18 and the bottle cap 19 are detachably connected. That is, the bottle body 18 and the bottle cap 19 are separably connected. Thus, when the filter material 20 reaches the specified service life, the bottle cap 19 can be unscrewed to replace the filter element. It should be noted that during the process of replacing the filter material 20, only the bottle cap 19 needs to be unscrewed, and there is no need to separate the bottle body 18 from the middle shell of the water purification device. To ensure the connection strength between the bottle body 18 and the middle shell, one end of the bottle body 18 is snap-connected to the middle shell, and the other end is locked to the middle shell by screws.

[0049] The water purification device according to an embodiment of the invention includes the pre-filter element 100 of the above embodiment. Since the inlet and outlet water circuits of the pre-filter element 100 according to the embodiment of the present invention are simply and clearly connected and easy to disassemble and assemble, the water circuit connection of the water purification device according to the embodiment of the present invention is convenient and easy to disassemble and assemble.
