Embodiment 1
[0042] Example 1: Please refer to Figure 1-4 , a variable frequency constant pressure water supply assembly, including an electric control cabinet 1, a water pump group 2, a pressure tank 3, a water supply pipe 4, a water collecting mechanism 5, a telescopic mechanism 6 and a water storage tank 7, and the interior of the electric control cabinet 1 is fixedly installed with electric Control system and ABB inverter, electric control cabinet 1 is electrically connected with water pump group 2, water pump group 2, air pressure tank 3 and water supply pipe 4 are all arranged on the left side of electric control cabinet 1, and the water inlet end of water supply pipe 4 is connected to the storage The water tank 7 is fixedly connected and communicated, the interior of the water storage tank 7 is fixedly installed with a filtering mechanism 10, and the filtering mechanism 10 adopts a reverse osmosis membrane filtration mechanism, and the reverse osmosis membrane filtration mechanism i...
Embodiment 2
[0046] Example 2: Please refer to Figure 5-6 , on the basis of the first embodiment, the undulations of the outer wall of the bellows 56 are sleeved with the rubber sleeve 13, the rubber sleeve 13 is in the shape of a circular ring and the side close to the bellows 56 is in a hollow state, and the rubber sleeve 13 shrinks in the bellows 56 When the bellows 56 is stretched, it is also in a contracted state and is attached to the outer wall of the bellows 56. The inner wall of the bellows 56 is provided with a through hole 14 at the position corresponding to the rubber sleeve 13. After the bellows 56 is stretched, the rubber sleeve 13 will also stretch. The through hole 14 is used to accommodate part of the water, and then when the water collecting mechanism 5 is stopped, the rubber sleeve 13 also shrinks during the shrinkage process of the bellows 56, and the stored water is squeezed out. Water is used to flush the inner wall of the bellows 56. Through the setting of the rubbe...
Embodiment 3
[0049] Example 3: Please refer to Figure 7-8 , On the basis of the second embodiment, the bottom surface of the connecting pipe 55 is fixedly connected with the water purification tank 17, the interior of the clean water tank 17 is hollow and communicated with the connecting pipe 55, and the bottom surface of the scraper 16 is provided with five water inlet grooves A18, the scraper Inside 16, a water inlet tank B19 is opened above the water inlet tank A18, the water inlet tank B19 is connected with the five water inlet tanks A18, the top surface of the water inlet tank B19 is provided with a water outlet hole 20, and the inner wall of the water outlet hole 20 is fixedly connected with a water supply pipe 21, One end of the water supply pipe 21 away from the water outlet hole 20 is fixedly connected and communicated with the clean water tank 17, and the filter screen 22 is fixedly installed on the inner wall of the water inlet tank A18. And between the scraper 16, the process ...
