The top of the guide hole is provided with a section of first internal thread, and the upper part of the excircle of the adjusting plunger is provided with a section of external thread corresponding to the first internal thread.
And a section of second internal thread is arranged at the bottom of the guide hole.
Wherein, the top of the adjusting plunger is provided with a cross groove or a straight groove.
Wherein, the bottom of the adjusting plunger is provided with a silica gel gasket.
And the tail ends of the water inlet hole and the water outlet hole are respectively provided with a section of third internal thread.
The utility model has the advantages that: the utility model provides a position height of annular basin can be adjusted to filter water route regulation lid, through the rotation of adjusting the plunger, realizes the switch of water route between washing and filtering, and is easy and simple to handle, and the structure is succinct moreover, and the cost of production and maintenance is low.
Drawings
Fig. 1 is a schematic structural view of the opening of the cleaning waterway of the present invention;
fig. 2 is a schematic structural view of the filtering waterway opening device of the present invention.
Detailed Description
The technical solution of the present invention is further explained by the specific embodiment with reference to fig. 1 to fig. 2.
The filter waterway regulation cover as shown in fig. 1 and 2 includes: lid 1 and adjusting plunger 2, 1 bottom indent of lid is provided with recess 11, 1 top indent of lid is provided with the guiding hole 3 with recess 11 intercommunication, 3 bottoms in guiding hole are provided with one section second internal thread 10, make things convenient for the installation and the dismantlement of cylindric filter screen.
Adjusting plunger 2 sets up in guiding hole 3, 3 tops of guiding hole are provided with one section first internal thread 5, 2 excircle upper portions of adjusting plunger are provided with one section external screw thread that corresponds with first internal thread, adopt threaded connection. The adjusting plunger 2 is characterized in that a circle of annular water groove 13 is concavely arranged on the outer circle of the adjusting plunger 2, the position height of the annular water groove 13 can be adjusted through rotation of the adjusting plunger 2, switching of a water path between flushing and filtering is achieved, operation is simple and convenient, a cross groove or a straight groove 4 is formed in the top of the adjusting plunger 2, and rotation operation is conveniently performed by adopting a screwdriver.
And a water inlet hole 6 communicated with the guide hole 3 is formed in one side of the cover body 1 and used for leading water flow in. Be provided with the blind hole 9 that upwards extends in the recess 11, 1 one side of lid is provided with apopore 7 with blind hole 9 intercommunication, and apopore 7 is used for filtering leading out of back rivers. The tail ends of the water inlet hole 6 and the water outlet hole 7 are respectively provided with a section of third internal thread, so that the connection of a water inlet pipe and a water outlet pipe is facilitated.
The bottom of the adjusting plunger 2 is provided with a silica gel gasket 12, and after the adjusting plunger 2 rotates and moves downwards, the silica gel gasket 12 can be used for plugging the lower part of the guide hole 3, as shown in figure 1, and the sealing performance is good.
Be provided with the water route regulation hole 8 with blind hole 9 intercommunication in the guiding hole 3, as shown in fig. 1, water route regulation hole 8 diameter is less than inlet opening 6, and inlet opening 6 and water route regulation hole 8's position altitude phase difference is almost, through the rotation of adjusting plunger 2, can adjust annular water tank 13 and adjust plunger 2's position altitude, realizes the switching of water route between washing and filtering:
firstly, as shown in fig. 1, when the bottom of the adjusting plunger 2 is positioned below the water inlet 6, the annular water tank 13 is communicated with the water inlet 6 and the water path adjusting hole 8, a clean water path is opened, reverse impact of the cylindrical filter screen is performed from the outer side, and a switch at the bottom of the cylindrical filter screen is opened, so that waste water can be discharged;
secondly, as shown in fig. 2, when the adjusting plunger 2 moves up in a rotating manner so that the annular water tank 13 moves up and is dislocated with the water path adjusting hole 8, the water path adjusting hole 8 is closed, and at the moment, the bottom of the adjusting plunger 2 is located at the bottom of the water inlet hole 6, so that water flows into the filter screen, the filtering water path is opened, and the operation is simple and convenient.
