DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] See also Figure 1-3 In this embodiment, a mechanical filter that is easy to clean includes a communicating vessel 1 connected to a liquid path of the device and a filtering structure located on the communicating vessel 1, wherein the filtering structure includes a filter element 5 and an installation chamber 3 for installing the filter element 5, wherein a threaded plunger 4 is fixedly installed on the upper end of the installation chamber 3, the communicating vessel 1 adopts a three-way design, and the threaded plunger 4 and one end of the communicating vessel 1 are connected to each other.

[0024] In a specific implementation, both ends of the communicating vessel 1 are provided with communicating tubes 2, and the two communicating tubes 2 respectively constitute the inlet and outlet of the filter, so that the liquid flows out from the other side after entering the filter element 5 for filtration, completing the filtration process.

[0025] In this embodiment, a reversing structure is also provided in the communicating vessel 1 for completing the flow guidance of the filtered liquid. The reversing structure includes a reversing tube 12 rotatably mounted on the top wall of the communicating vessel 1 and a driving member 14 for pulling the reversing tube 12 to move.

[0026] Preferably, the reversing tube 12 is a two-way pipeline, and an extension tube 13 is integrated on the outer wall of the reversing tube 12 . The extension tube 13 is connected perpendicularly to the reversing tube 12 , and the lower end of the reversing tube 12 is inserted into the upper end opening of the filter element 5 .

[0027] Such a design enables the reversing tube 12 and the inside of the filter element 5 to communicate with each other, and the inside of the filter element 5 can be communicated with through the extension tube 13 .

[0028] It should be noted that the diameter of the extension tube 13 corresponds to the connecting tube 2 , and a sealing ring is built into the connecting end of the connecting tube 2 and the communicating vessel 1 , and the extension tube 13 corresponds to the connecting tube 2 by rotation.

[0029] In a specific implementation, the extension tube 13 can be connected to the connecting tube 2 on one side under the squeezing effect of the sealing ring.

[0030] The driving member 14 in this embodiment is a conventional electric motor, the power end of the driving member 14 is fixedly connected to the reversing tube 12, and a protective cover 15 is also installed on the outside of the driving member 14. In another embodiment, the driving member 14 can also be an L-shaped bending rod extending to the outside of the communicating vessel 1, and one end of the bending rod is fixedly connected to the reversing tube 12.

[0031] By manually rotating the bending rod extending to the outside of the communicating vessel 1, the orientation position of the reversing tube 12 can be conveniently rotated and adjusted manually.

[0032] In this embodiment, a blocking structure is provided on the inner bottom wall of the mounting chamber 3 , and the blocking structure includes a blocking plug 8 threadedly connected to the mounting chamber 3 and a connecting seat 6 corresponding to the blocking plug 8 .

[0033] Preferably, the connecting seat 6 is in a truncated cone shape and is integrally fixed to the lower end of the filter element 5 , and a groove 9 corresponding to the connecting seat 6 is formed at the upper end of the sealing plug 8 , and the connecting seat 6 can be plugged into the groove 9 .

[0034] In a specific implementation, by lifting the sealing plug 8 relative to the mounting chamber 3, the filter element 5 can be stabilized by the abutment of the sealing plug 8 and the reversing tube 12. At the same time, when the sealing plug 8 is loosened, the filter element 5 can be easily loosened and removed.

[0035] It should be noted that a sealing tube 10 is fixedly installed on the top of the sealing plug 8, and a socket 7 corresponding to the sealing tube 10 is penetrated through the connecting seat 6. The sealing tube 10 is plugged into the socket 7. Through the sealing tube 10, the lower end of the filter element 5 can be closed.

[0036] Such a design can also allow the filtered impurities to be retained in the cavity in the middle of the filter element 5 for storage.

[0037] In order to facilitate the rotation of the sealing plug 8 , a connecting column 11 is fixedly installed at the lower end of the sealing plug 8 in this embodiment. By rotating the connecting column 11 , the sealing plug 8 can be conveniently rotated.

[0038] It is worth noting that a sealing ring should also be arranged on the inner bottom wall of the installation liner 3 to reduce the connection gap between the sealing plug 8 and the installation liner 3.

[0039] The working principle of the above embodiment is:

[0040] By rotating the reversing tube 12, the extension tube 13 on the reversing tube 12 rotates to the connecting tube 2 on one side, and the connecting tube 2 corresponding to the extension tube 13 is used as the liquid inlet, and the mechanical liquid path is passed from the connecting tube 2 on this side into the extension tube 13, and the liquid enters the reversing tube 12 and the inside of the filter element 5 along the extension tube 13. The liquid inside the filter element 5 is filtered by the filter element 5 and seeps to the position between the outside of the filter element 5 and the installation tank 3. When the liquid increases, the filtered liquid spreads back to the inside of the communicating vessel 1 and flows out from the connecting tube 2 on one side connected to the communicating vessel 1. When cleaning is required, the control driving member 14 drives The reversing tube 12 rotates relative to the communicating vessel 1, and the extension tube 13 on the reversing tube 12 corresponds to the connecting tube 2 on the other side. At this time, the mechanical liquid circuit is controlled to transport cleaning water, so that the water passes through the connecting tube 2 on the side that is not connected to the extension tube 13 and enters the installation tank 3, and penetrates into the filter element 5, and the impurities accumulated in the filter element 5 are discharged along the reversing tube 12, the extension tube 13 and the connecting tube 2 connected to the extension tube 13 to achieve flushing. At the same time, when systematic cleaning is required, the installation tank 3 together with the filter element 5 can be removed from the communicating vessel 1 by rotating the connecting column 11 at the lower end and the installing tank 3, so that the filter element 5 can be removed and cleaned.
