The end of the pin 134 remote from the handle member 130 is provided with a retaining member 132, and the retaining member 132 and the end of the handle member 130 are located on the inner and outer sides of the end wall 124, thereby restricting the handle member 130 from being separated from the end wall 124.
According to some embodiments of the present invention, the anti-slip member 132 is a stopper protrusion disposed at an end of the pin 134 remote from the handle member 130. The edge of the pin hole 126 is provided with a notch 128, the shape and the size of the notch 128 are matched with the shape and the size of the limiting bulge, and the notch 128 is used for enabling the limiting bulge to pass through.
It will be appreciated that when the handle member 130 is mounted to the end wall 124, the handle member 130 may be mounted to the end wall 124 with the retention tabs corresponding to the location of the notches 128. The handle member 130 includes an open position in which a force can be applied to the handle member 130 to enable handling, installation, and removal of the filter cartridge assembly 100, and a closed position. At the same time, in the open position, the stop tab avoids notch 128, i.e., the stop tab prevents hands-free hand piece 130 from disengaging from end wall 124.
In some embodiments, end wall 124 is formed with two escape slots 140, with slot bottoms 142 of two escape slots 140 arranged in parallel, with pin holes 126 at slot bottoms 142.
It will be appreciated that the two relief grooves 140 are recessed relative to the surface of the end wall 124, and the two ends of the handle member 130 are clamped at the two relief grooves 140. The escape slot 140 allows the handle member 130 to have a rotational angle that allows the handle member 130 to be switched between an open position and a closed position. Meanwhile, the avoiding groove 140 can accommodate the end of the handle part 130, so as to prevent the end of the handle part 130 from protruding out of the end wall 124, thereby reducing the volume of the filter element assembly 100 and the water purifying device, and facilitating the installation and use of users.
In some embodiments, a side of the end plate 122 away from the housing 110 is formed with a receiving groove 150, and the receiving groove 150 is used for receiving the handle member 130.
It will be appreciated that in the open position, the handle member 130 is rotated to the side of the end plate 122 remote from the housing 110, and force may be applied to the filter cartridge assembly 100 by the handle member 130. In the closed position, the handle member 130 is engaged in the receiving groove 150, and the receiving groove 150 has a shape and a size corresponding to those of the handle member 130. The handle member 130 is placed in the receiving groove 150 without increasing the volume of the filter cartridge assembly 100.
When the filter element assembly 100 is located in the body 200 of the water purifying apparatus, the filter element assembly 100 can be removed from the body 200 by switching the handle member 130 from the closed position to the open position. When the filter element assembly 100 is installed, the filter element assembly 100 is installed in the machine body 200 through the handle part 130, and then the handle part 130 is switched to the closed position, so that the handle part 130 can be prevented from occupying the space in the machine body 200, and the size of the filter element assembly 100 and the water purifying device can be reduced.
In some embodiments, in the closed position, an orthographic projection of the handle member 130 in the plane of the end panel 122 is flush with the edge of the end panel 122.
