As shown in fig. 4, the supporting component 4 is provided with a second fastener 12 adapted to fasten the residual chlorine generator 13. Specifically, the residual chlorine generator 13 includes: the body, and locate the projection of body both sides, every projection card is located in a second buckle 12. The supporting component 4 can also be fixedly connected with a salt shortage alarm device. Through the residual chlorine generator 13 clamped on the supporting component 4, the salt shortage alarm device is fixedly connected to the supporting component 4, and the fixed connection with each structure in order can be conveniently realized on the supporting component 4, so that the assembly is convenient.

In order to assemble the supporting component 4 above the salt box 1 conveniently, a plurality of first positioning structures can be uniformly arranged on the salt box 1, and a plurality of second positioning structures which are matched and connected with the first positioning structures are uniformly arranged on the supporting component 4, so that the salt box is convenient to assemble and has a more attractive appearance; in order to assemble the cover body structure 5 above the supporting component 4, a plurality of third positioning structures are uniformly arranged on the supporting component 4, and a plurality of fourth positioning structures which are connected with the third positioning structures in a matched mode are uniformly arranged on the cover body structure 5, so that the appearance is attractive when the assembly is convenient. As an alternative embodiment, the first positioning structure, the second positioning structure, the third positioning structure and the fourth positioning structure may be arranged non-uniformly.

Specifically, as shown in fig. 6, 8 and 9, the first positioning structure is a positioning groove 15, and the second positioning structure is a positioning rib 14; the third positioning structure is a positioning hole 16, and the fourth positioning structure is a positioning buckle 17. Because the positioning rib 14 and the positioning hole 16 are both disposed on the supporting component 4, the positioning rib 14 and the positioning hole 16 can be disposed back to back on the supporting component 4 and respectively located on different surfaces of the supporting component 4. Through with location muscle 14 and locating hole 16 back to back setting on supporting component 4, be located the different surfaces of supporting component 4 respectively for bump the perforation when 14 demolding of accessible location muscle directly form the locating hole 16 at its back, can effectively utilize the space of supporting component 4, and can make things convenient for the demolding of mould, can reduce unnecessary structure on the supporting component 4 simultaneously. As an alternative embodiment, the positioning ribs 14 and the positioning holes 16 may be provided on the support member 4 independently.

As shown in fig. 10, the support assembly 4 further comprises a multi-way valve 18, the multi-way valve 18 comprises a valve head 19 and a bypass 20, the valve head 19 is screwed on the tank opening of the resin tank 3, one end of the bypass 20 is connected with the valve head 19, and the other end is suitable for being connected with a water outlet pipe; the support assembly 4 further comprises a bypass seat 21 on which the bypass 20 is placed. In particular, the bypass seat 21 can be fixed to the support assembly 4 by means of screws or snap-on. The bypass seat 21 is arranged on the support component 4, the bypass 20 is placed, the installation position of the bypass 20 can be positioned, a gap between the multi-way valve 18 and the support component 4 can be filled, and the appearance of the whole machine is beautified.

Specifically, as shown in fig. 5, a U-shaped groove 22 is formed on the bypass seat 21, and the bypass 20 is disposed in the groove 22. The groove 22 is formed in the bypass seat 21, and the bypass 20 is arranged in the groove 22, so that the mounting positions of the valve head 19 and the bypass 20 can be found more conveniently during assembly of the multi-way valve 18, and the assembly is more convenient.

The first buckle 11 on the supporting component 4 is arranged outside the threaded rotating range of the valve head 19; the second fastener 12 is arranged in the threaded rotation range of the valve head 19, and the highest end surface of the second fastener 12 is lower than the lower end surface of the valve head 19 in the lowest mounting position. Because the valve head 19 is in threaded connection with the tank opening of the resin tank 3, the valve head 19 needs to be rotated to be fixedly connected onto the tank opening of the resin tank 3 during installation, the first buckle 11 of the supporting component 4 is arranged outside the threaded rotation range of the valve head 19, the second buckle 12 is arranged in the threaded rotation range of the valve head 19, the highest end face of the second buckle 12 is lower than the lower end face of the valve head 19 at the lowest installation position, namely the lower end face of the valve head 19 screwed at the tank opening of the resin tank 3, the valve head 19 can be prevented from being rotated and interfered by other structures on the supporting component 4, and the maximization of space utilization is realized. In an alternative embodiment, the second catch 12 may be provided outside the range of the valve head 19 in which the thread turns, or the first catch 11 may be provided within the range of the valve head 19 in which the thread turns, but the highest end surface of the first catch 11 may be lower than the lower end surface of the valve head 19 in the lowest mounting position.

During the assembly, can put into salt case 1 with resin jar 3 earlier salt valve 2, the top of salt case 1 is detained through the buckle to supporting component 4, valve head 19 of multiple unit valve 18 is screwed on the jar mouth of resin jar 3 through the screw thread, install bypass seat 21 on supporting component 4, then install bypass 20 of multiple unit valve 18 on bypass seat 21, it fixes into second buckle 12 to remain chlorine generator 13 in, fix power connection 9 on supporting component 4 through mount pad 23, and compress tightly electric wiring 10 in first buckle 11, at last with lid structure 5 joint in the top of supporting component 4.

The resin tank 3 is firstly installed in the salt tank 1, the resin is canned after being fixed with the support component 4, and then the valve head 19 of the multi-way valve 18 is screwed, so that the assembly mode that the resin tank 3, the support component 4 and the multi-way valve 18 are fixed outside the salt tank 1 and then are placed in the salt tank 1 is more convenient, the difficulty of an operator can be greatly reduced, because the valve head 19 of the multi-way valve 18 needs to be screwed on the tank opening of the resin tank 3 through screw thread rotation, the design needs to consider that the structural member on the support component 4 needs to be out of the rotation range of the valve head 19, so that the rotation range of the valve head 19 is not hindered by a structure, such as the first buckle 11 and the buckle for connecting the support component 4 and the cover body structure 5, the positioning rib 14 for connecting the support component 4 and the salt tank 1 is arranged out of the rotation range of the valve head 19, and the highest end surface position of the second buckle 12 is arranged to be lower than the lowest end surface of the valve head 19 after the valve, the accommodating structure 8 of the supporting component 4 can be set to be a hemispherical structure, and then the second buckle 12 is placed on the accommodating structure, because the hemispherical structure of the accommodating structure 8 is high in the middle and low in the edge, the height difference can be well utilized, and the space utilization maximization of the limited space is realized.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
