In the lower surface of cover board, supporting element applies pressure from upper direction snap ring, and supporting applies to snap ring from below accepts power, and the two will
Snap ring is clamped in centre, makes snap ring keep stablizing, then filtering net cylinder is not easy to loosen, more steady to the fixation of filtering net cylinder
It is fixed, help to ensure that filter effect.
Detailed description of the invention
Fig. 1 is the cross-sectional view for the filter device that a kind of anti-filter screen of embodiment of the utility model loosens；
Fig. 2 is a kind of structural schematic diagram of the filtering net cylinder of embodiment of the utility model from water inlet direction.
Specific embodiment
The utility model is described in further detail below by specific embodiment combination attached drawing.
The utility model embodiment provides a kind of filter device that anti-filter screen loosens, as shown in Figure 1 comprising setting exists
Water inlet 11, water outlet 12 and the sewage draining exit 13 at the top of filter device on filter device surface, filter device inside tool
There is the flowing water chamber being respectively communicated with water inlet 11, water outlet 12 and sewage draining exit 13, be provided with filtering net cylinder 2 flowing water is intracavitary,
Water enters flowing water chamber from water inlet 11, exports after the filtering of filtering net cylinder 2, then from water outlet 12.On the sewage draining exit 13
Equipped with the cover board 3 for the detachable capping sewage draining exit 13.When needing to clean filtering net cylinder 2, openable lid
Plate 3 takes out filtering net cylinder 2.
The radius of the snap ring 21 with outward extension on the outer peripheral surface of the filtering net cylinder 2, snap ring 21 is greater than filter screen
The radius of cylinder 2 simultaneously surround entire filtering net cylinder 2.It is equipped on the inner wall of the flowing water chamber of the filter device and accepts ring 14, accepted
Ring 14 is annular in shape, and internal diameter is less than the radius of snap ring 21 and is greater than the radius of filtering net cylinder 2.The undertaking ring 14 is set in filtering
The outside of net cylinder 2 and the snap ring 21 are hung on the undertaking ring 14, and filtering net cylinder 2 will be hung under self gravitation effect
It accepts on ring 14, this structure setting takes out filtering net cylinder 2 from undertaking ring 14.
The supporting element 4 upwardly extended is equipped on the snap ring 21, supporting element 4 can be made of hard plastic, work as institute
The lid of cover board 3 is stated when overlaying on sewage draining exit 13, the supporting element 4 is connected to the lower surface of cover board 3.Supporting element 4 is from upper direction snap ring 21
Apply pressure, supporting 14 applies to snap ring 21 from below accepts power, and snap ring 21 is clamped in centre by the two, keeps snap ring 21
To stablize, then filtering net cylinder 2 is not easy to loosen, and it is more stable to the fixation of filtering net cylinder 2, help to ensure that filter effect.
In one embodiment, as shown in Fig. 2, supporting element top 41 is arc-shaped, and entire arcwall face pastes lid
The lower surface of plate 3, the contact surface of this arc surfaced can increase the contact area with cover board 3, and the thrust that cover board 3 provides is more steady
It is fixed, the held stationary in loading process of supporting element 4, it is not easy to skew occur.
