Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a straight-through basket filter. Background Art

[0002] After searching, application number 202023311019.8 discloses a straight-through basket filter, including an installation box, a top cover is detachably connected to the top of the installation box, a filter box is installed inside the installation box, and the filter box includes: an outer shell and a cover plate, the cover plate is detachably connected to the outer shell by screws, a water inlet extending into the filter box is installed on the left side of the installation box, a water outlet extending into the filter box is installed on the right side of the installation box, and a filtering device is installed in the filter box.

[0003] During use, a straight-through basket filter in this patent application is driven by a handle to move the pull rod upward. At this time, the spring is in a stretched state. The handle is then released to drive the pull rod downward by the elastic force of the spring. The downward movement of the pull rod drives the vibration plate to vibrate the filter box. The vibration of the filter box drives the first filter screen and the second filter screen to vibrate, so that garbage on the first filter screen and the second filter screen falls into the garbage box, making cleaning more convenient. However, during such use, the method of cleaning the first filter screen and the second filter screen by vibration is likely to cause damage to the device, reducing the service life of the device. For this reason, we propose a straight-through basket filter. Utility Model Content
