[0044] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, water valves are provided at the ends of the water supply pipe 6, the connecting pipe 7 and the water delivery pipe 8. It should be noted that water valves are provided at the ends of the water supply pipe 6, the connecting pipe 7 and the water delivery pipe 8, and the delivery of water sources is controlled by the water valves. Since the water valve is a prior art in this field, it is not elaborated in detail, and the specific model and specifications of the water valve need to be selected and determined according to the actual specifications of various water pipes.

[0046] It should be noted that: in order to facilitate the installation of the filter 10, an outer frame is set outside the filter 10 and connected to the inner wall of the water supply pipe 6. During the cleaning process, the slide plate 1205 drives the cleaning brush 11 to move up and down along the surface of the filter 10 inside the outer frame. At the same time, the length of the cleaning brush 11 is greater than or equal to the diameter of the outer frame, so that it can fully sweep the impurities on the surface of the filter 10, thereby improving the cleaning quality.

[0047] The use method and advantages of the utility model: When the secondary water supply device with anti-corrosion function is working, the working process is as follows:

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the municipal water supply pipe is connected to the water storage tank, and the water source is sent to the water supply tank 2 for storage. During the secondary water supply, the water source is controlled by the water valve to be transported to the water supply pipe 6 and respectively transported to the combined water pipe 8 for users to use. During use, the water quality is filtered through the filter 10. The filter 10 is prone to clogging after long-term use. When cleaning it, start the second motor 1202 to drive the screw 1203 to rotate, and the slide bar 1204 sleeved on the outside of the screw 1203 immediately drives the slide plate 1205 to slide down, so that the cleaning brush 11 at the end of the slide plate 1205 sweeps back and forth along the surface of the filter 10, thereby cleaning the impurities filtered on the surface of the filter 10, avoiding long-term use clogging to affect the permeability of the water source, and through automated cleaning, the labor intensity of the staff can be reduced and the cleaning efficiency can be improved.

[0049] The inner wall of the water supply tank 2 will produce scale after long-term use. When cleaning the scale, the first motor 502 is started to drive the transmission rod 503 to drive the driving gear 504 to rotate. When the driving gear 504 rotates, it meshes with the driven gears 505 at both ends. The rotating shaft 506 in the middle of the driven gear 505 rotates immediately. When rotating, the sector gear 507 coaxially sleeved on the outside rotates at the same time and meshes with the tooth plate 508. The two sector gears 507 rotate at the same time. When one sector gear 507 meshes with the tooth plate 508, it drives the tooth plate 508 to slide up, and the end of the tooth plate 508 is connected The slider 3 drives the scraper 4 to slide along the inner wall of the water supply tank 2 to scrape it. As the fan gear 507 continues to rotate, the other fan gear 507 engages with the tooth plate 508 to drive the tooth plate 508 to slide down. The tooth plate 508 drives the scraper 4 at the end of the slider 3 to slide along the inner wall of the water supply tank 2. As the two fan gears 507 rotate, the tooth plate 508 is driven to achieve a reciprocating sliding effect, so that the scraper 4 can slide back and forth to clean the scale on the inner wall of the water supply tank 2, thereby preventing the scale from accumulating on the inner wall of the water supply tank 2 and causing corrosion to it, thereby increasing its service life.

[0050] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
