Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 in conjunction with fig. 2-4, an embodiment of the present invention includes:

a suction cup device with a check valve and a filtering function comprises a suction cup 1, a valve tongue 2, a welding sheet 3 and a filter screen 4.

The sucker 1 comprises a water suction cavity 101, a check cavity 102 and a water outlet cavity 103 which are communicated from bottom to top, and is used for completing the adsorption and guiding of water in an environment with relatively severe water quality.

The bottom of the water suction cavity 101 of the sucker 1 is correspondingly provided with a filter screen 4 and is fastened through a bolt 5 to form an integrated structure, so that the filter screen 4 is stably fixed on the sucker 1. The filter screen 4 is provided with 1 at least evenly distributed's through-hole 6, the aperture d size of through-hole 6 is phi 1~ phi 10mm, reduces and passes through the particulate matter diameter, prevents that large granule thing from getting into the jam water pump.

The water suction cavity 101 top of the sucker 1 is provided with a welding sheet 3 and forms an integrated structure through ultrasonic welding, so that the use stability of the welding sheet 3 is ensured. The welding piece 3 is provided with a diversion opening 7 turned towards the non-return cavity 102 to facilitate the circulation of water flow. The flow guide port 7 is provided with a valve tongue 2, and the valve tongue 2 is matched with the flow guide port 7 to form a check valve function. Welding piece 3 is provided with three reference column 11 in sucking disc 1 border one side, border one side of valve tongue 2 is provided with three locating hole (the drawing is not drawn), the three locating hole of valve tongue 2 overlaps respectively on three reference column 11 of welding piece 3, it is spacing that three location boss 12 corresponds with three reference column 11 top in the non return chamber 102, through reference column 11 and location boss 12 with valve tongue 2 spacing on reference column 11, avoid valve tongue 2 to drop and influence the check valve function.

Sucking disc 1 absorb water chamber 101 top one side and be provided with three location boss 11, it corresponds the joint at the border of three location boss 11 and is provided with welding piece 3 to absorb water chamber 101, welding piece 3 is provided with the water conservancy diversion mouth 7 that turns over towards the non return chamber, welding piece 3 is provided with three reference column 12 in 1 border one side of sucking disc, border one side of valve tongue 2 is provided with three locating hole (the drawing does not draw), the three locating hole of valve tongue 2 overlaps respectively on three reference column 12 of welding piece 3

The valve tongue 2 covers the flow guide opening 7 of the welding sheet 3 downwards under the action of gravity, and when water is filled from the water filling opening of the water pump, water can be stored in the pipeline and the cavity of the water pump to discharge air in the cavity of the water pump and the pipeline. When the water pump is started, water in the cavity of the water pump is thrown out continuously due to the centrifugal action, and meanwhile, the valve tongue 2 is opened due to the suction action, so that water flow continuously enters the pipeline to form circulation, and therefore water drainage work is carried out. When the water pump stops working, water in the cavity of the water pump and the pipeline can impact the valve tongue 2 downwards, so that the valve tongue 2 is attached to the flow guide opening 7 of the welding piece 3, the bottom of the water is accumulated in the non-return cavity 102, and the water in the cavity of the water pump and the pipeline is prevented from flowing out. Therefore, the water can be repeatedly used only by one-time irrigation.

An upward inclination angle alpha is arranged on the top of the flow guide opening 7 in the horizontal direction, the lower end of the inclination angle alpha is located on one side of the fixed end of the valve tongue 2, the angle of the inclination angle is 0-5 degrees, and in a natural state, the valve tongue 2 can be better attached to the flow guide opening 7 of the welding sheet 3 due to the action of gravity to block the position of the flow guide opening 7, so that the irrigation work is completed. However, the valve tongue 2 may not be attached to the valve body and may leak water during the continuous opening and closing process. By designing an upward inclined angle on the diversion port 7, the valve tongue 2 and the diversion port 7 can be better attached together, and the occurrence of leakage caused by the fact that the valve tongue 2 cannot be attached to the diversion port can be reduced.

The water outlet cavity 103 is correspondingly provided with a transverse water outlet 8 at the opposite side of the fixed end of the valve tongue 2, the water outlet 8 is provided with an upward elevation angle beta in the horizontal direction, the angle of the elevation angle beta is 0-20 degrees, so that the assembly manufacturability is met, and meanwhile, when a pipeline is connected, the whole sucker 1 is not easy to turn on one side.

The sum of the sectional areas of the through holes 6 is larger than or equal to the size of the water outlet 8 of the water outlet cavity 103, so that the working efficiency of the water pump is ensured.

The cavity 101 that absorbs water is provided with counter weight 9 in the correspondence of the side below of a water cavity 103 that goes out, counter weight 9 corresponds spacingly through fixing the stopper 10 at the cavity 101 top that absorbs water, when putting into aquatic with sucking disc 1, can make whole sucking disc 1 sink to the bottom and be difficult for appearing turning on one's side. If the suction cup 1 floats on the water surface due to light weight, the irrigation work may not be completed and air may enter the pipeline, resulting in interruption of water flow during the drainage process.

When the water pump is used, the sucker is horizontally placed into water, the water outlet of the sucker and the water inlet of the water pump are connected together through a special pipeline, the phenomenon of air leakage at two ends of the pipeline cannot occur in the process, then the water filling plug at the pump end is screwed to fill water, and due to the fact that the density of the water is high, air can be gradually discharged from the pipeline in the water filling process until the pipeline and the cavity of the water pump are completely filled with the water, the water filling plug is screwed at the moment, and the water pump is started to drain water.

In conclusion, the suction disc device with the check valve and the filtering function, which is disclosed by the utility model, has the advantages of simple and reasonable structure, convenience in installation and safety in use, and can improve the efficiency of the water pump and prolong the service life of the water pump.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
