The invention discloses a direct drinking water purification and supply
system with a self-cleaning function, which comprises a reaction kettle, the top end of the reaction kettle is connected with a top cover, the top end of the top cover is communicated with a feeding
pipe, the bottom end of the reaction kettle is fixedly connected with a
liquid storage tank, the
liquid storage tank is communicated with a conducting
pipe, and the bottom end of the reaction kettle is provided with a through hole communicated with the
liquid storage tank, the bottom end of the through hole is provided with a sealing
assembly. According to the direct drinking water purification and supply
system with the self-cleaning function, the
liquid storage tank is arranged, and a spraying
assembly is arranged in the
liquid storage tank, so that a solution in the
liquid storage tank is conveyed to a spray head through a pump body in the spraying
assembly, the side wall of the reaction kettle is sprayed through the spray head, and an arranged driving part drives the spray head to rotate, so that the spray head can uniformly spray on the side wall of the reaction kettle, the problem that a large amount of solution needs to be treated for treating scale is solved by spraying the solution on the side wall of the reaction kettle, and the problem that the preparation cost of direct drinking water is high is further solved.
