[0022] The following will be combined with the attached embodiment of the present invention Figure 1-9 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1-9 As shown, a water softener with selectable valve positions comprises:

[0024] The lower box 7 has an opening on its upper side, which is used to accommodate a round soft water tank and soft water salt. Figure 3 As shown;

[0025] The lower plate seat 6 is fixed to the upper opening of the lower box body 7 and has a through hole 602 for accommodating a round soft water tank. Figure 6 , 7 As shown;

[0026] Upper cover 1, such as Figure 1 As shown, the lower side of the upper cover 1 is detachably connected to the upper side of the lower plate seat 6, the inner cavity of the upper cover 1 accommodates the valve seat at the upper end of the soft water tank, and the side wall of the upper cover 1 is provided with three selectable valve installation areas surrounding the upper cover 1 in the lateral direction, and the valve installation areas can be more numerous;

[0027] A pair of valves 3 are arranged side by side, respectively used for water inlet and water outlet, and connected to the valve seat of the soft water tank. The valve 3 is detachably installed in a valve installation area of ​​the upper cover 1 facing the water pipe interface. The circular soft water tank can be rotated and adjusted in the through hole 602, so as to conveniently adjust the position of the water inlet and outlet interface of the valve seat on the top of the soft water tank so that the interface of the valve seat is opposite to and connected to the valve 3.

[0028] Therefore, according to the above content, the specific installation position and orientation of the valve 3 can be selected according to the position of the water pipe to be connected on site. The pair of valves 3 in this embodiment has three optional installation directions, making the operation more flexible.

[0029] like Figure 4 , 5 As shown, each valve installation area of ​​the side wall of the upper cover 1 is provided with an installation opening 101, and a decorative plate 2 detachably installed in the installation opening 101 is also provided, and the valve 3 is detachably connected to one of the decorative plates 2, so as to facilitate the installation of the valve 3.

[0030] like Figure 5 , 6 As shown, the side wall of the upper cover 1 is also provided with a panel mounting portion 103 for mounting the control panel 4, which is staggered from the valve mounting area, so as to facilitate the installation of the control panel 4 of the water softener.

[0031] like Figure 2 , 3 As shown, the lower box body 7 is also provided with a salt adding port which is integrated with the upper opening thereof, and a salt bin flap 5 which can be opened and closed is rotatably connected to the salt adding port of the lower box body 7. When the salt bin flap 5 is closed, the salt bin flap 5 is consistent with the upper cover 1, the lower plate seat 6 and the lower box body 7; the outer surface of the salt bin flap 5 forms a continuous surface with the outer surfaces of the upper cover 1, the lower plate seat 6 and the lower box body 7, thereby facilitating the opening and closing operations of the salt bin flap 5 and maintaining the beautiful appearance of the product.

[0032] As a further structural optimization solution, the outer surface of the salt bin flap 5 has an area aligned with the control panel 4 when the salt bin flap 5 is closed.

[0033] Based on the left and right lateral viewing angles, the salt adding port of the lower box body 7 is set as a flip cover positioning groove 701. Figure 3 As shown, the rotation connection point of the salt bin flap 5 is higher than the lowest point of the flap positioning groove 701; the closing side of the salt bin flap 5 has a flap positioning surface 102, and when the salt bin flap 5 is in a closed state, the flap positioning surface 102 of the salt bin flap 5 coincides with the flap positioning groove 701, thereby facilitating accurate positioning of the closed position of the salt bin flap 5.

[0034] like Figure 1 , 2 As shown, the outer surfaces of the upper cover 1, the lower plate seat 6, and the lower box body 7 are sequentially connected to form a continuous surface, such as Figure 7-9 As shown, the inner surface of the upper cover 1 has a plurality of locking strips 104 extending from top to bottom to the lower side of the upper cover 1 , and the lower side of the upper cover 1 has an upper positioning step 105 extending along the lower edge of the upper cover 1 .

[0035] The upper side of the lower plate seat 6 is provided with a lower positioning step 604, which extends along the upper edge of the lower plate seat 6. When the upper cover 1 and the lower plate seat 6 are assembled, the locking strip 104 is abutted against the inner wall of the lower plate seat 6, and the upper positioning step 105 on the lower side of the upper cover 1 is consistent with the lower positioning step 604 on the upper side of the lower plate seat 6.

[0036] like Fig. 9 As shown, the outer area of ​​the lower side of the upper cover 1 has an upper positioning plate 105a that is convex downward and has an installation gap between it and the locking strip 104. The upper positioning plate 105a extends as a whole along the lower edge of the upper cover 1, and the upper positioning plate 105a and the lower side surface of the upper cover 1 constitute the upper positioning step 105.

[0037] The inner area of ​​the upper side of the lower plate seat 6 has an upwardly convex lower positioning plate 604a, which extends along the upper edge of the lower plate seat 6 as a whole, and the lower positioning plate 604a and the upper side surface of the lower plate seat 6 constitute the lower positioning step 604.

[0038] When locking, the lower positioning plate 604a is inserted into the installation gap between the locking strip 104 and the upper positioning plate 105a. When the upper cover 1 and the lower plate seat 6 are detachably fixed together, the locking strip 104 presses the lower positioning plate 604a against the inner plate surface of the upper positioning plate 105a, forming the first positioning means between the upper cover 1 and the lower plate seat 6.

[0039] At the same time, the inner plate surface of the upper positioning plate 105a has a plurality of locking protrusions 106, and the lower positioning plate 604a has a plurality of lower locking holes 605. In the locked state, the locking protrusions 106 are detachably fixed and inserted into the lower locking holes 605 one by one, forming a second positioning means for the upper cover 1 and the lower plate seat 6. Through double positioning, the upper cover 1 and the lower plate seat 6 can be firmly combined.

[0040] like Figure 7 As shown, the center of the lower plate seat 6 has a recessed portion 601, a through hole 602 is provided at the bottom of the recessed portion 601, the recessed portion 601 has a plurality of radial slits 603 surrounding and connecting the through hole 602, and the radial slits 603 as a whole extend radially outward along the through hole 602, thereby reducing the contact stress between the through hole 602 and the soft water tank.
