The filter chamber 5 is connected to the total water inlet 2 and the connecting device 7, the connecting device 7 is connected to the multi-stage impeller device 8, the multi-stage impeller device 8 is connected to the outer cavity 10, and the outer cavity 10 is connected to the water outlet 3. The filter chamber 5 and the outer cavity 10 are integrally formed.

[0041] To elaborate further, an observation port A8 connected to the filter chamber 5 is provided on the top of the shell 1, and the observation port A8 is provided with a first sealing cover A9, which is threadedly connected to the observation port A8. The first sealing cover A9 is made of transparent material, and the filter device 4 includes a filter part A10 and a connecting part A11. The connecting part A11 is used to connect the filter part A10 to the first sealing cover A9 and the connecting device 7. The sealing cover seals the observation port A8 to prevent external dust from entering the filter chamber 5 and prevent water in the filter chamber 5 from leaking out. When it is necessary to check the status of the filter device 4, rotate the first sealing cover A9 and observe the status of the filter device 4 through the observation port A8. Corresponding maintenance can also be performed through the observation port A8.

The first filter screen A13 in this embodiment is lengthened. The existing filter screen is longer, so that the first filter screen A13 can work for a longer time, and the filtering effect will not be reduced due to impurities blocking part of the sieve holes. The structure of the connection part A11 is used to ensure the stability of the filter device 4 when working and reduce the shaking of the filter device 4. When the filter device 4 needs to be cleaned, the water outlet 3 needs to be sealed first, the main water inlet 2 and the first drain port A18 need to be opened, and the liquid enters the shell 1 and can only leave from the first drain port A18, thereby flushing the first filter screen A13 and brushing off the impurities on the first filter screen A13. The connecting seat A17 is made of smooth material, so that impurities are not easily adsorbed on the connecting seat A17.

Due to the setting of the first one-way valve B9, the liquid in the outer cavity 10 will not enter the inner cavity B3 through the first opening B8, and the liquid can move from the inner cavity B3 through the first opening B8 to the outer cavity 10. After use, the first sealing cover A9 can be opened, and the first drainage channel B10 and the second drainage channel B11 can be opened. The inner cavity B3 is drained through the first drainage channel B10, and the outer cavity 10 is drained through the second drainage channel B11. By discharging the liquid in the shell 1, it can effectively prevent the liquid from corroding the internal parts and increase the service life of the water pump. The second filter screen B20 can filter the liquid entering the inner cavity B3, leaving impurities, and discharge them through the first drainage channel B10, reducing the impact of impurities on the multi-stage impeller device 8 and facilitating subsequent cleaning.

When the removable section B14 is removed, the fixed section B13 will be connected to the first drainage channel B10. This setting is used to ensure that during normal use, the liquid in the inner cavity B3 will not enter the outer cavity 10 through the first drainage channel B10 and the fixed section B13. Similarly, the liquid in the outer cavity 10 will not enter the inner cavity B3 through the first drainage channel B10 and the fixed section B13. A first give way groove B15 is provided to facilitate the installation of the removable section B14. At the same time, a first installation groove B16 for installing the sealing ring is provided to increase the sealing performance and prevent the liquid in the fixed section B13 from leaking into the first drainage channel B10 from the gap.
