Of course, the water purifying assembly can be used for other water purifying equipment besides the electric water heater, and is not specifically recited herein. The following description will take an example of the water purifying assembly used in the electric water heater.

Specifically, the water outlet purification assembly comprises a water outlet pipe 500 and a water purification sleeve 800, wherein the water outlet pipe 500 is positioned in the inner cavity 120 of the liner 100, the water outlet end of the water outlet pipe 500 is maintained in a state of facing the highest point of the inner cavity 120, a water outlet of the water outlet pipe 500 is provided with hot water flowing into the water outlet of the water outlet pipe 500, the water purification sleeve 800 is sleeved on the water outlet pipe 500, a storage space is formed between the inner wall surface of the water purification sleeve 800 and the outer wall surface of the water outlet pipe 500, the storage space is used for placing water purification substances, and the water purification sleeve 800 is provided with a water passing hole 801 in a penetrating manner.

Because outlet pipe 500 sets up the upper strata of inner chamber 110 of inner bag 100, the hot water layer of inner bag 100, this goes out water purification module through the water purification sleeve 800 cover that will be provided with the water purification material and establishes on outlet pipe 500, consequently make the cover establish the water inlet sleeve 800 on outlet pipe 500 and lie in the hot water layer equally to the hot water of hot water layer has purified, has improved the quality of water of the hot water that flows in from inner bag 100, has satisfied user's user demand, has promoted user's use experience. And, the water purification sleeve 800 is sleeved on the water outlet pipe 500 in a simple installation mode, no additional connecting piece is needed, no additional punching is needed on the liner wall of the liner 100, so that the phenomenon of structural strength reduction of the liner 100 caused by the need of punching when the water purification sleeve 800 is installed does not occur, the service life of the liner 100 is prolonged, and the risk of water leakage of the liner 100 is reduced.

Because of the variety of water purification materials for improving water quality, different water purification materials can improve water quality from different aspects, for example, the water purification materials can be scale inhibitors, ores or chlorine scavengers, etc., and can realize the functions of scale inhibition, mineralization, chlorine removal, etc. And since different water purification materials are adapted to function at different temperatures, the water inlet sleeve 800 is at a higher temperature and is adapted to store water purification materials adapted to function at lower temperatures.

As shown in fig. 7, 9 and 10, the water outlet pipe 500 is a curved pipe, the water outlet pipe 500 includes two ends of a water outlet end and a connection end, an opening at the water outlet end is a water outlet, hot water in the liner 100 can enter the water outlet pipe 500 through the water outlet, and the connection end of the water outlet pipe 500 is fixed on the liner 100, so as to fix the water outlet pipe 500.

In some specific embodiments, the first stiffener 613 is an annular stiffener and is disposed circumferentially around the first pipe portion. In some specific embodiments, the number of the first reinforcing ribs 613 is plural, and the plural first reinforcing ribs 613 are disposed at intervals along the axial direction of the first pipe portion. This arrangement further increases the structural strength of the first connection pipe 610.
