Description

Plumbing filter

The utility model relates to a kind of dewatering installation, specifically a kind ofly is used for the device that sink or bathtub prevent that drain gully from stopping up.

Along with the raising of people's living standard, the used sink of family, hotel, bathtub etc. tend to superior more,, also have higher requirement for the downspout device that matches with it for this reason, have both required attractive in appearancely, require functional diversities again.In order to solve the problem that the tank washer drain mouth blocks, having invented the patent No. is that " 86211016 " " the kitchen sink sewer antiplugging device " and the patent No. are " 88207106.8 " " wash basin sewer antiplugging device ", though they all have good retaining, anti-blocking function, but it manipulates inconvenience, and product-forming and inherent quality lag behind broad masses of the people's requirement.The patent No. is " 93243211.5 ", " a kind of family expenses trap drainage device ", it is handsome in appearance, simple in structure, can prevent effectively that sewer from stopping up, but when also existing retaining, drain hole is not tightly stifled, easily produce the seepage phenomenon, in addition, connect with nut between its inside and outside bowl, so make the processing more complicated.

The utility model provides a kind of multi-functional plumbing filter handsome in appearance, graceful, simple in structure at the deficiencies in the prior art to society.

Task of the present utility model is achieved in that this plumbing filter is made up of a housing and base, the centre bore of fixed screw by housing and base is both sockets, be evenly equipped with exhalant canal around the centre bore of housing and base, place one and filter chock plug on housing, it is that entity has the filter lid of filter opening and the sealing ring and the positioner that are fixed under the filter lid are formed by a center; This positioner can be the cylindrical guide pillar that a center has through hole, and the packing ring that it passes the band shoulder spins with the handle of filtering the side of covering, and sealing ring is fixed on filter lid below; This positioner also can be the spiral pawl of a band shoulder, sealing ring is positioned on the shoulder of spiral pawl, it is chimeric to cover the handle that entity projects upwards by upper end and filter, sealing ring is fixed on filter lid below, it is uniform that spiral pawl lower end is three-jaw, breach between three-jaw shape in the shape of a spiral extends upward, and stretches in the uniform on every side exhalant canal of housing centre bore.

As long as the utility model will filter chock plug and up carry gently or be rotated counterclockwise, sealing ring and housing drain gully break away from, draining, and foreign material are held on filter and cover.Downwards by or turn clockwise, sealing ring and the driving fit of housing drain gully, retaining can discharge water.The utility model is simple in structure.Good looking appearance, and collection draining, retaining, filtration three functions are one.

Below in conjunction with embodiment the utility model is further described.

Fig. 1 is an embodiment of the present utility model.

Fig. 2 is another embodiment of the present utility model.

Fig. 3 is the partial schematic diagram of spiral pawl among Fig. 2.

Embodiment 1, as shown in Figure 1, figure middle shell 3 is enclosed within the base 1, and fixed screw connects both by the centre bore of housing 3, base 1, be evenly equipped with three or four exhalant canals around the centre bore of housing 3, base 1, lay sealing ring 2 between housing 3 and base 1 bead.The top of housing 3 is equipped with one and filters chock plug, and it is by the filter lid 4 of filter opening be fixed in sealing ring 9 and the positioner that filter covers under 4 and form around the entity by a center.The positioner of this embodiment is a cylindrical guide pillar 7, and the center has through hole, and the outer wall of through hole is outwards heaved, and the packing ring 8 that the band shoulder is passed in these guide pillar 7 upper ends spins with filtering the handle 5 that covers 4 tops, sealing ring 9 is fixed on filter covers 4 below.Insert in the centre bore of fixed screw 7 lower end of guide pillar 6, and guide pillar 7 and centre bore are for movingly, and its outer wall plays the drum place and is interference fit.Housing 3 of the present utility model, filter are covered 4 and are stainless steel or copper one-tenth, and base 1, guide pillar 6, packing ring 8 and handle 5 can form with plastic injection-moulded.Whole drowning leakage device is installed on the drain gully place of sink or bathtub, and its lower end is connected with outlet pipe with connector 10.In the time of need discharging water, as long as handle 5 is upwards carried gently, sealing ring 9 cover 4 with filter to be separated with the drain gully of housing 3, and the filter opening of the logical filtering cover 4 of water is from the exhalant canal discharge of housing 3 and base 1, and dirt impurity just stockpiles in filter and covers.When needing retaining, as long as handle 5 is pressed downwards, the drain gully driving fit of sealing ring 9 and housing 3, tank can be filled with water since guide pillar to play the drum place be interference fit with fixed screw 7 endoporus, so handle one is carried and can be let go when discharging water, use very convenient.Mention whole filtration chock plug, can remove foul.

Embodiment 2, as Fig. 2, shown in Figure 3, the positioner of the filtration chock plug of housing 3 tops is spiral pawls 11 that have shoulder, sealing ring 9 is placed on the shoulder of spiral pawl 11, the upper end of spiral pawl 11 is embedded in filter and cover in the real rectangle handle 5 that goes out of entity, and sealing ring 9 is fixed on to filter covers 4 below, and spiral pawl 11 lower ends are that three-jaw 12 is uniform, breach between pawl and the pawl extends upward twist, and this three-jaw 12 inserts in housing 3 centre bores three drowning passages on every side.All the other structures are identical with embodiment 1, no longer repeat at this.During use, as long as handle 5 is rotated toward clockwise direction, the spiral pawl moves downwards, it is 4 descending that sealing ring 9 is covered with filter, and with the drain gully driving fit of housing 3, can water blockoff, retaining, handle is rotated toward counter clockwise direction, upwards operation of spiral pawl 11 makes sealing ring 9 separate with the drain gully of housing 3, gets final product draining.Filter covers if foreign material are arranged, and can easily whole filtration chock plug be mentioned and remove totally.
