Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.

As shown in FIGS. 1-5; kitchen sewer water pressure mediation piston includes:

the piston body 1 is a cylinder with a through hole in the middle. The outer side surface of the connecting piece is provided with a groove, and the inner side surface of the connecting piece is provided with threads for connecting the connector 3 in a thread fixing mode;

a sealing ring 2 providing a sealing surface capable of sealing contact with a sewer;

the hollow joint 3 arranged in the piston body 1 is preferably a stainless steel wire joint. The diameters of the upper part and the lower part of the connector are small, the middle part is an annular shoulder 31 which is common in the field of connectors, and the diameter of the middle part is larger than that of the upper part and the lower part of the connector 3; shoulder 31 may also preferably be a hexagonal body to facilitate wrench movement. The shoulder 31 facilitates axial positioning of the nipple 3 relative to the piston body 1. The lower part of the joint 3 is provided with an external thread which is matched with the piston body 1. The upper part of the joint 3 is also provided with external threads, so that the water pipe 4 can be conveniently connected in a threaded connection mode, the water pipe 4 is preferably communicated with a water source after a metal woven cold and hot water inlet hose commonly used in the field of kitchen and bath, and a three-way angle valve type valve 5 is preferably selected. The valve 5 is communicated with a water source. The valve 5 is preferably a water inlet switch with one inlet and two outlets commonly used in the kitchen and bath field, so that one outlet is convenient for normal kitchen water use operation, and the other outlet is convenient for kitchen port operation of dredging a sewer and cleaning the sewer. In addition, it should be understood by those skilled in the art that the higher the water pressure that the valve 5 can provide, the higher the water pressure entering the piston body 1 from the valve 5, and the better the dredging effect. According to different application structures of a sewer in a kitchen, the installation positions of the sealing ring 2 and the piston body 1 are different.

The sealing ring 2 is sleeved outside the groove of the piston body 1, so that the sealing ring 2 can be replaced conveniently and timely when the sealing ring is damaged. It will be appreciated by those skilled in the art that there may be a plurality of grooves on the piston body 1 corresponding to the number of seal rings 2. In addition, the piston is not limited to be used in a kitchen, and is also suitable for other sewers.

The first embodiment is as follows:

as shown in fig. 1, the elastic sealing ring 2 is sleeved in the groove; the outer side surface of the sealing ring 2 is contacted with the pipe wall of a sewer, and the inner side surface and the outer side surface of the sealing ring 2 play a role in sealing; the sealing ring 2 is clamped between the outer side surface of the piston body 1 and the inner side surface of a sewer. Namely, the dredging piston is arranged in the sewer. The structure and installation of the sealing ring 2 are common technical means in the field of hydraulic sealing, and are not described herein. According to the national standard, the outer diameter of a kitchen sewer is 50 mm, the kitchen sewer is also called as a 50-degree sewer pipe in the industry, on the basis, the actual inner diameters of the sewer pipes produced by various sewer pipe manufacturers are slightly different, the inner diameter difference is compensated by utilizing the elastic deformation of the sealing ring 2, the piston with the sealing ring 2 is tightly contacted with the inner wall of the sewer, and the sealing effect is achieved.

Example two:

as shown in fig. 3, for the flat state around the port of the sewer, for example, the top view of the kitchen sink shown in fig. 4-5, the sealing ring 2 is pressed under the piston body 1, so that the sealing ring 2 is clamped between the bottom surface of the piston body 1 and the top surface of the sewer. According to the common state of the kitchen sink, the sealing ring 2 is clamped between the bottom surface of the piston body 1 and the kitchen floor drain cover 10 for sealing. Therefore, water enters the middle of the piston body 1 through the water pipe 4 and the joint 3, then passes through the sealing ring 2, and finally passes through the kitchen floor drain cover 10. Due to the different shapes of the kitchen drain cover 10, it is common to have a plurality of through holes arranged in a circular array along the center of the drain opening as shown in fig. 4-5. The sealing ring 2 is placed at the position of dotted line as shown in figure 4 and figure 5, and the kitchen floor drain cover 10 is enclosed, so that water in the water pipe 4 can enter a sewer through the sealing function of the inner side surface of the sealing ring 2 and the kitchen floor drain cover 10. At this moment, the groove on the outer side surface of the piston body 1 is used for sleeving the sealing ring 2 outside the groove when the sealing ring 2 is not needed, so that the sealing ring 2 is prevented from being lost. When the piston is not used, the piston is connected to one outlet of the valve 5 in a similar way to the connection mode of the embodiment, and the outlet at the other end of the valve is free; when the piston is needed to be dredged, the sealing ring 2 on the outer side of the groove is taken down, force is manually applied to the piston body 1, and the sealing ring 2 is tightly pressed between the kitchen floor drain cover 10 and the bottom surface of the piston body 1 to be sealed.

Example three:

as shown in fig. 2, an annular slider is provided above the axially outer end face of the upper portion of the joint 3;

one end of the movable rod 6 is provided with a sliding hole matched with the annular sliding block so as to realize that the movable rod 6 is rotatably connected with the piston body 1, and the other end of the movable rod penetrates through the inside of the joint 3. The mounting end of the movable rod 6 is preferably a circular ring structure which is lapped on the axial outer end face of the upper part of the joint 3, the bottom surface of the circular ring is provided with a circle of circular sliding holes, and the matching form of the sliding holes and the circular sliding holes is convenient for the movable rod to perform circular motion around the axis of the joint 3. The design of the part is that most people are used to poke a sewer with needle rod type articles, but the needle rod type articles are easy to lose due to infrequent use. The movable rod 6 is movably lapped on the joint 3 through the matching form of the sliding hole and the annular sliding hole. When in use, the movable rod 6 can be separated from the joint 3 for independent use; the position of the movable lever 6 may be changed by manually rotating the attachment end of the movable lever 6 while directly placing the movable lever on the joint 3. After use, the movable rod 6 is mounted on the joint 3. The size of the annular slider is not larger than the outer diameter of the joint 3, and the detachable connection of the water pipe 4 and the joint 3 through a threaded connection mode is not influenced.

Furthermore, a plurality of needle columns are protruded out of the outer side surface of the free end of the movable rod 6, and the needle columns are arranged in a barb shape, so that food residues can be hung conveniently.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
