DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 The utility model provides a technical solution, a water storage type water supply pressurizing device with an anti-backflow structure, comprising a water supply pipe 1 and an anti-backflow mechanism 4, one end of the water supply pipe 1 is connected to a pressurizing pump 2, the other end of the water supply pipe 1 is connected to a water storage tank 3, the anti-backflow mechanism 4 is arranged inside the water supply pipe 1, and a filtering mechanism 5 is arranged inside the water supply pipe 1;

[0020] The anti-backflow mechanism 4 includes a check ring 401, a support plate 402, a first sealing ring 403, a push rod 404, a check block 405, a baffle 406 and a spring 407. The check ring 401 is arranged inside the water supply pipe 1, and the support plate 402 is arranged inside the water supply pipe 1. The first sealing ring 403 is embedded in the check ring 401, and the push rod 404 runs through the support plate 402. One end of the push rod 404 is fixedly connected to the check block 405, and the other end of the push rod 404 is fixedly connected to the baffle 406. A spring 407 is sleeved on one side of the surface of the push rod 404. Through the arrangement of the check ring 401, the support plate 402, the first sealing ring 403, the push rod 404, the check block 405, the baffle 406 and the spring 407, when in use, when the water supply pipe 1 is in use, the water supply pipe 1 is in use. When the water inside the water pipe 1 flows forward, the water flow pushes the check block 405 to move, the check block 405 drives the push rod 404 to move, the push rod 404 drives the baffle 406 to move, so that the baffle 406 pulls the spring 407 to stretch and deform, and the check block 405 is disengaged from the first sealing ring 403, so that the water flow can be supplied normally. When the water inside the water supply pipe 1 does not flow or flows back, the spring 407 is not reset by external force or is reset by the backflow water, so that the spring 407 drives the baffle 406 to reset, the baffle 406 drives the push rod 404 to reset, and the push rod 404 drives the check block 405 to reset, so that the check block 405 is abutted against the first sealing ring 403 to form a sealing structure, thereby preventing the water inside the water supply pipe 1 from flowing back.

[0021] Furthermore, one end of the spring 407 is fixedly connected to the support plate 402, and the other end of the spring 407 is fixedly connected to the baffle 406. Through the setting of the spring 407, when in use, the spring 407 will stretch and deform when pulled. When the stretching force disappears, the spring 407 will reset due to its own characteristics, so that the spring 407 can provide power for the reset movement of the baffle 406.

[0022] Furthermore, the check ring 401 is fixedly connected to the water supply pipe 1, the support plate 402 is fixedly connected to the water supply pipe 1, the check block 405 is abutted against the first sealing ring 403, and through the setting of the support plate 402, when in use, the support plate 402 can provide support for the push rod 404 and the spring 407, and the support plate 402 can limit the position of the push rod 404 and the spring 407.

[0023] Furthermore, the filtering mechanism 5 includes a blocking block 501, a second sealing ring 502, a retaining ring 503, a filter screen 504, an adsorption chamber 505 and a dirt box 506. The blocking block 501 is connected to a flange on one side of the surface of the water supply pipe 1, and a second sealing ring 502 is arranged inside the water supply pipe 1. The retaining ring 503 is fixedly connected to one side of the surface of the blocking block 501. The filter screen 504 is engaged with one side of the surface of the blocking block 501. The adsorption chamber 505 is engaged with one side of the surface of the blocking block 501. The surface of the filter screen 504 is connected to one side of the dirt box 506. By setting the blocking block 501, the second sealing ring 502, the retaining ring 503, the filter screen 504, the adsorption chamber 505 and the dirt box 506, when in use, when water flows through the filter screen 504 and When the adsorption chamber 505 is in the adsorption chamber, the filter screen 504 can filter the particles in the water and collect the particles in the dirt box 506. The activated carbon in the adsorption chamber 505 can absorb tiny impurities in the water and remove odors. When it is necessary to replace the activated carbon and clean the dirt box 506, first, open the flange to separate the block 501 from the water supply pipe 1. At this time, take out the block 501 to clean the filter screen 504, the adsorption chamber 505 and the dirt box 506, so as to avoid the deterioration of the filtering effect due to long-term use. After cleaning, fix the block 501 to the water supply pipe 1 through the flange. At this time, the retaining ring 503 and the second sealing ring 502 abut each other to form a sealing structure, so as to avoid water leakage at the block 501.

[0024] Furthermore, the retaining ring 503 is in contact with the second sealing ring 502, and the interior of the adsorption chamber 505 is filled with activated carbon particles. Through the setting of the second sealing ring 502, when in use, the second sealing ring 502 can form a sealed environment by pressing against the retaining ring 503, thereby preventing the water inside the water supply pipe 1 from leaking through the gap between the block 501 and the water supply pipe 1.

[0025] Furthermore, the filter 504 is connected to the adsorption chamber 505, and the filter 504 is arranged in the middle position between the adsorption chamber 505 and the dirt box 506. Through the setting of the dirt box 506, when in use, the dirt box 506 can receive the particles filtered by the filter 504 and collect the particles, thereby facilitating subsequent cleaning.

[0026] Working principle: When the water inside the water supply pipe 1 flows forward, the water flow pushes the check block 405 to move, the check block 405 drives the push rod 404 to move, the push rod 404 drives the baffle 406 to move, so that the baffle 406 pulls the spring 407 to stretch and deform, and the check block 405 is separated from the first sealing ring 403, so that the water flow can be supplied normally. When the water inside the water supply pipe 1 does not flow or flows back, the spring 407 is not reset by external force or is reset by the backflow water, so that the spring 407 drives the baffle 406 to reset, the baffle 406 drives the push rod 404 to reset, and the push rod 404 drives the check block 405 to reset, so that the check block 405 abuts against the first sealing ring 403 to form a sealing structure, thereby preventing the water inside the water supply pipe 1 from flowing. Backflow, when the water flows through the filter 504 and the adsorption chamber 505, the filter 504 can filter the particles in the water and collect the particles inside the dirt box 506. The activated carbon inside the adsorption chamber 505 can adsorb tiny impurities in the water and remove odors. When it is necessary to replace the activated carbon and clean the dirt box 506, first open the flange to separate the block 501 from the water supply pipe 1. At this time, take out the block 501 to clean the filter 504, the adsorption chamber 505 and the dirt box 506, so as to avoid the decline of filtering effect due to long-term use. After cleaning, fix the block 501 to the water supply pipe 1 through the flange. At this time, the retaining ring 503 and the second sealing ring 502 abut against each other to form a sealing structure, so as to avoid water leakage at the block 501.
