[0026] The following detailed description provides various embodiments or examples for implementing the present invention. These are, of course, merely examples and are not intended to be limiting. Furthermore, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. This repetition is for simplicity and clarity in describing the present invention and does not imply a specific relationship between the various embodiments and / or configurations discussed.

[0027] like Figure 1-Figure 5 The shown embodiment shows a pre-placed stainless steel filter bottle with a scale inhibitor filter element, comprising a filter bottle 1, a water purification filter element 2 arranged in the filter bottle 1, and an end cover 3 covering the opening of the filter bottle 1, wherein a water inlet 4 and a water outlet 5 are respectively provided on both sides of the end cover 3, a filter element connecting platform 6 is provided inside the end cover 3, a water inlet 7 communicating with the water outlet 5 is provided on the filter element connecting platform 6, a support assembly is provided on the filter element connecting platform 6, and a scale inhibitor filter element 40 and a water purification filter element 2 are sequentially provided on the support assembly, the scale inhibitor filter element 40 is fitted between the filter element connecting platform 6 and the water purification filter element 2, and an adjustable pressing assembly for pressing the water purification filter element 2 is detachably installed at the end of the water purification filter element 2 away from the filter element connecting platform 6.

[0028] Firstly, by providing the antiscalant filter element 40, the function of antiscaling can be achieved while filtering. In addition, there is no need to install additional antiscaling equipment on the pipeline, thus reducing costs.

[0029] When installing the scale inhibitor filter element 40 and the water purification filter element 2, the scale inhibitor filter element 40 and the water purification filter element 2 can be supported by the supporting assembly first, and then the water purification filter element 2 can be pressed against the scale inhibitor filter element 40 by the adjustable pressing assembly, so that the scale inhibitor filter element 40 is installed more firmly to avoid water leakage. The overall structure is simple and easy to install, and the adjustable pressing assembly can press the water purification filter element 2 of different lengths and specifications, and has strong applicability.

[0030] It should be noted that the water purification filter element 2 is a filter element structure commonly used in existing filters and will not be described in detail here.

[0031] See also Figure 2 、 Figure 3 、 Figure 5 As shown, the support assembly includes a pipe sleeve 21 arranged at the outer end of the water outlet 7, and a bowl-shaped piece 22 is arranged outside the pipe sleeve 21. The pipe sleeve 21 can be inserted into the water purification filter element 2, and the outer end edge of the bowl-shaped piece 22 can be against the end wall of the water purification filter element 2; thereby allowing the water purification filter element 2 to better fit on the water purification filter element connecting platform 6 and be connected to the water outlet 7, and it is less likely to cause water cross-contamination problems.

[0032] See also Figure 2 As shown, the adjustable clamping assembly includes a center tooth bar 31 and a water purification filter element pressure cap 32. One end of the center tooth bar 31 passes through the water purification filter element pressure cap 32 and is fixed in the water outlet 7, and the other end is threadedly connected to the water purification filter element pressure cap 32; when installing the water purification filter element 2, the water purification filter element 2 is sleeved on the center tooth bar 31, and the inner end of the water purification filter element 2 is supported by the supporting assembly, and then, the water purification filter element pressure cap 32 is threadedly connected to the outer end of the center tooth bar 31, and the water purification filter element 2 is compressed by the water purification filter element pressure cap 32. The structure is simple, and installation and disassembly are convenient. At the same time, it can adapt to the installation of water purification filter elements 2 of different lengths and specifications.

[0033] See also Figure 2 、 Figure 3 、 Figure 5 As shown, the scale inhibitor filter element 40 includes an annular filter shell 400 which is sleeved on the outside of the bowl-shaped piece 22, and scale inhibitor particles 401 are arranged in the annular filter shell 400; the annular filter shell 400 prevents the scale inhibitor particles 401 from flowing everywhere, and the effect is relatively more sufficient than that of bulk scale inhibitors contacting the water flow; thereby, the variable scale components in the water can be well removed while the filter is filtering, and the scale inhibitor particles can fully react with the water flow, so as to conveniently and quickly solve the scale problem generated during the subsequent heating process of the water flow.

[0034] In consideration of long-term use, in order to prevent scale particles from passing through the annular filter housing 400 of the scale-inhibiting filter element, the diameter of the scale inhibitor particles 401 can be reduced as much as possible, thereby achieving a better scale-inhibiting effect of the scale-inhibiting filter element.

[0035] See also Figure 1 、 Figure 2 、 Figure 4 As shown, a bolt 41 is threadedly connected to the end of the filter bottle 1 away from the end cover 3, a sealing pressure plate 42 is provided at the inner end of the bolt 41, an exhaust hole 43 is provided at the outer end of the bolt 41, a side hole 44 connected to the exhaust hole 43 is provided on the side of the bolt 41 located on the sealing pressure plate 42, and a sealing rubber ring 51 is provided on the inner side of the sealing pressure plate 42.

[0036] When exhaust operation is required, the side hole 44 is unscrewed from the threaded hole by tightening the bolt 41, and at the same time the sealing rubber ring 51 on the sealing pressure plate 42 is separated from the inner wall of the filter bottle 1, so that gas can enter from the side hole 44 and be discharged from the exhaust hole 43, thereby realizing the exhaust function. Compared with the traditional spring-pressed exhaust valve, this structure is more durable and reliable.

[0037] In order to improve the stability of the bolt 41 , a fastening nut 61 is connected to the bolt 41 and is located on the external thread of the filter bottle 1 .

[0038] See also Figure 1 、 Figure 2 As shown, a drain valve 71 is provided on the water outlet 5, so that the water in the filter bottle 1 can be completely drained when the water purification filter element 2 is to be replaced, avoiding the problem of wetting the floor when replacing the water purification filter element.

[0039] In the present invention, a bracket 91 for supporting the end cover 3 is further provided on the end cover 3, and a plurality of mounting holes 92 are provided on the bracket 91. Through the provision of the bracket 91, the stainless steel filter bottle can be placed on the ground or in a cabinet as a whole for easy transportation. In addition, the stainless steel filter bottle can be mounted and fixed on the wall in various directions through the bracket 91, or directly mounted and fixed on the ground.
