Modes for Carrying Out the Invention

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0023] As shown in Figures 1 to 5, the filtering device used in the water pump includes a shell 1 and a filtering device 2. The shell 1 is provided with a accommodating chamber 3 for accommodating the filtering device 2, an impeller 20 and a water outlet chamber 4 for connecting to the impeller 20. The shell 1 is provided with a water inlet 5 and a water outlet 6. The accommodating chamber 3 is connected to the water inlet 5. The accommodating chamber 3 is provided with an opening 7 for connecting to the impeller 20. The filtering device 2 is arranged at the opening 7. The filtering device 2 is used to filter impurities in the liquid. The water outlet chamber 4 is connected to the water outlet 6. The accommodating chamber 3 and the water outlet chamber 4 are integrally formed.

[0024] To elaborate further, the accommodating chamber 3 is cylindrical, and an observation port 8 communicating with the accommodating chamber 3 is provided on the top of the shell 1. The observation port 8 is provided with a sealing cover 9, and the sealing cover 9 is threadedly connected to the observation port 8. The accommodating chamber 3 is set to be cylindrical, and the observation port 8 and the sealing cover 9 are set to be circular, which is convenient for the staff to replace the filter device 2. Only the sealing cover 9 needs to be opened to directly replace or clean the filter device 2. At the same time, since the accommodating chamber 3 is cylindrical, the accommodating chamber 3 can be adapted to a variety of filter devices 2, such as the filter element 17 in Figure 4 of the specification, and the filter device 2 in Figure 2 of the specification can also be used, which increases the compatibility of the accommodating chamber 3. When the water pump is in use, the sealing cover 9 will open the observation port 8. 8 is sealed to prevent external dust from entering the receiving tank and prevent water in the receiving tank from leaking out. When it is necessary to check the status of the filter device 2, rotate the sealing cover 9 and observe the status of the filter device 2 through the observation port 8. The corresponding maintenance can also be carried out through the observation port 8. At the same time, before using the water pump, liquid can be added through the observation port 8 so that there is liquid in the water outlet cavity 4, which can ensure the normal use of the water pump. The sealing cover 9 is made of transparent material. This setting allows the operator to observe the status of the filter device 2 directly through the sealing cover 9 without opening the sealing cover 9, so that the staff does not need to disassemble the water pump for inspection and can directly observe through the observation port 8, which is convenient.

[0025] 3 and 5; the filter device 2 includes a filter portion 10, a smooth portion 27 and a connecting portion 11, the connecting portion 11 is used to connect the opening 7, the smooth portion 27 is arranged between the connecting portion 11 and the filter portion 10, and the connecting portion 11 is hollow. After the liquid passes through the filter portion 10, it moves from the middle of the connecting portion 11 to the opening 7. Impurities that cannot pass through the filter portion 10 will accumulate between the filter device 2 and the accommodating chamber 3 and cannot enter the opening 7. At the same time, a smooth portion is provided so that impurities cannot be adsorbed on the smooth portion. Since the filter portion 10 in this application adopts an extended setting, after long-term use, the accumulation of impurities will only block the filter holes in the lower half, and the upper half of the filter portion 10 can still filter the liquid, that is, the water pump can still be used normally. This design allows us to use it for a long time without disassembly and cleaning, which solves the disadvantage that the existing filter device needs to be installed in the water pump and needs to be cleaned or maintained regularly.

[0026] In further detail, the filter part 10 includes a plurality of support frames 12 and a plurality of filter screens 13 arranged on the support frames 12. The filter screens 13 in this embodiment are lengthened and longer than the existing filter screens 13, so that the filter screens 13 can work for a longer time and the filtering effect will not be reduced due to impurities blocking some of the sieve holes.

[0027] To elaborate further, a support top seat 21 is connected to the top of the support frame 12, and the support top seat 21 is provided with a through hole 22 for the filter 13 to pass through. A limit block 23 and a protrusion 24 for limiting the vertical movement of the limit block 23 are provided in the through hole 22. The limit block 23 is provided with a clearance notch 25, which is used to facilitate the disassembly of the filter 13. When the filter 13 needs to be disassembled, the limit block 23 is first rotated so that the clearance notch 25 is aligned with the protrusion 24, and the limit of the protrusion 24 on the limit block 23 is released. The limit block 23 is taken out, and then the filter 13 is taken out, cleaned or directly replaced, and reinstalled into the support frame 12.

[0028] To be more specific, a section of the filter portion 10 away from the connecting portion 11 is provided with a connecting groove 14, the limiting block 23 is provided with a connecting rod 15, and a slot 16 for inserting the connecting rod 15 is provided at the bottom of the sealing cover 9. This setting is used to ensure the stability of the filter device 2 during operation and reduce the shaking of the filter device 2. At the same time, this setting allows the staff to take out the filter device 2 for inspection and cleaning through the connecting rod 15 by simply opening the closing cover 9.

[0029] To elaborate further, a drain port 26 is provided near the connection portion 11 of the accommodating chamber 3. When a large amount of particulate matter adheres to the surface of the filter screen 13, the drain port 26 and the water inlet 5 can be opened, and the water outlet 6 can be closed to rinse the surface of the filter screen 13. The washed-down particulate matter leaves the accommodating chamber 3 from the drain port 26, reducing the need to replace the filter screen 13 or disassemble the filter device 2, and increasing convenience. At the same time, due to the provision of the smooth portion 27, the particulate matter cannot be adsorbed on the surface of the smooth portion 271 and leave from the drain port 26. At the same time, the particulate matter on the side of the connection portion 11 away from the drain port is pushed to the drain port 26 for cleaning, and all impurities are discharged from the drain port 26, thereby cleaning the impurities inside the accommodating chamber 3 and reducing the need to disassemble the water pump for maintenance and cleaning of the filter device 2.

[0030] In further detail, the sealing cover 9 is provided with a handle 19 for rotation, which makes it convenient for the operator to open or close the observation port 8.

[0031] Embodiment 2 of the filter device 2: as shown in FIG4 ; the filter device 2 adopts a filter element 17, and the filter element 17 is arranged at the opening 7. A fixing groove 18 for inserting and fixing the filter element 17 is provided at the bottom of the sealing cover 9. The use of the filter element 17 facilitates subsequent replacement, and can also ensure the effect of filtering impurities in the liquid.

[0032] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.

[0033] Although a large number of terms are used in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
