Description

Technical Field

[0001] The utility model relates to a waste water valve. Background Art

[0002] The waste water valve is a common valve used for discharging the waste water generated by a water purifier. The waste water valve of the prior art usually includes a housing, and the housing includes a water inlet pipe, a water inlet chamber, a water outlet pipe, a water outlet chamber and a valve flap. The water inlet pipe and the water outlet pipe are respectively communicated with the water inlet chamber and the water outlet chamber, and the valve flap can be lifted to form the switching of the opening and closing states of the waste water valve to switch the opening and closing states of the waste water valve. Since the waste water processed and discharged by the waste water valve is easy to crystallize, resulting in the blockage of the water inlet pipe and the water inlet chamber, and also considering the balance of internal pressure, a waste water hole is often provided between the water inlet chamber and the water outlet chamber. By always keeping the waste water hole communicating the water inlet chamber and the water outlet chamber, crystallization and internal pressure balance can be avoided. However, in the process of using the waste water hole of the prior art, since the aperture needs to be set relatively small, it is particularly easy to be blocked. Therefore, the prior art often sets a filter screen in the water inlet pipe to filter the waste water through the filter screen. This leads to that on the one hand, when the waste water valve is normally used, the waste water also needs to pass through the filter screen before entering the water inlet chamber, greatly increasing the workload of the filter screen and shortening the service life of the filter screen. On the other hand, during normal use, the filter screen will also affect the flow rate of the water inlet pipe, restricting the drainage capacity of the waste water valve. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides an anti-blocking waste water valve that can prevent blockage, has a longer service life and does not affect the drainage capacity.

[0004] To achieve the above object, the utility model provides an anti-blocking waste water valve, which includes a housing. A water inlet pipe, a water inlet chamber, a water outlet pipe, a water outlet chamber and a valve flap are arranged on the housing. The valve flap can be lifted to form the switching of the opening and closing states of the waste water valve. A filtering part is arranged in the water inlet chamber. A plurality of filter holes are arranged on the filtering part. A first inner cavity, a second inner cavity and a waste water hole are arranged on the water inlet pipe. The aperture of the filter holes is smaller than that of the waste water hole, and the filter holes are respectively communicated with the water inlet chamber and the first inner cavity. The waste water holes are respectively communicated with the first inner cavity and the second inner cavity. The second inner cavity is communicated to the outside.

[0005] The advantages of adopting the above technical solution are as follows: A filtering part with several filter holes is arranged in the water inlet cavity, and a first inner cavity, a second inner cavity and a waste water hole are arranged on the water inlet pipe. Then, the aperture of the filter holes is made smaller than that of the waste water hole. When the waste water valve is in the closed state, after the waste water enters the water inlet cavity through the water inlet pipe, it will enter the first inner cavity through several filter holes on the filtering part, then enter the second inner cavity through the waste water hole, and finally be discharged from the second inner cavity. In this process, the waste water is first filtered by the filter holes, which can avoid the blockage of the waste water hole, reduce the maintenance frequency, and the setting of several filter holes can still work normally even after partial blockage. Since the filter holes are no longer arranged in the water inlet pipe, when the waste water valve is opened, most of the waste water can directly enter the water outlet cavity without passing through the filter holes first, reducing the filtering pressure of the filter holes, further making the structure more durable and avoiding the influence of the filter holes on the flow rate.

[0006] The utility model can be further arranged as follows: A movable part is arranged in the water outlet pipe. The first inner cavity is arranged between one end of the movable part and the filtering part. The waste water hole is arranged at one end of the movable part. The second inner cavity is formed by the hollow of the movable part. A connection port communicating the water outlet cavity and the second inner cavity is arranged on the side wall of the movable part.

[0007] Through further arrangement, a movable part is arranged in the water outlet pipe, the first inner cavity is formed between one end of the movable part and the filtering part, the waste water hole is arranged at one end of the movable part, and finally the second inner cavity is formed by the hollow of the movable part. This enables the whole movable part to be taken out when the waste water valve needs to be maintained, and water is introduced through the water outlet pipe to clean and maintain the waste water valve, and then the movable part is cleaned separately, with good maintenance effect.

[0008] The utility model can be further arranged as follows: The movable part is cylindrical and has a convex part on its side wall. The movable part fits with the inner peripheral wall of the water outlet pipe, and a guiding groove for the convex part to extend into is arranged on the water outlet pipe.

[0009] Through further arrangement, a convex part and a guiding groove are respectively arranged on the peripheral walls of the movable part and the water outlet pipe. The cooperation of the convex part and the guiding groove can limit the movement of the movable part, avoiding the rotation of the movable part during normal use, which may cause its connection port not to align with the water outlet cavity. When maintenance is needed, it can be guided and pulled out through the cooperation of the convex part and the guiding groove.

[0010] The utility model can be further arranged as follows: The water outlet cavity is arranged in a circular groove shape with an opening at the upper part. The valve flap is arranged above the water outlet cavity and can be lifted and lowered by the drive of the motor to form or release the covering of the water outlet cavity. The water inlet cavity is arranged in a semi-circular groove shape and extends along the edge of the water outlet cavity in an arc shape, and one end of the water inlet cavity extends to the filtering part.

[0011] Through further setting, the water outlet cavity is arranged in a circular groove shape with an opening at the upper part. The valve flap is arranged above the water outlet cavity and can be driven by the motor to lift up and down to form or release the covering of the water outlet cavity. Thus, the valve flap can open or close the waste water valve under the drive of the motor. The water inlet cavity is arranged in a ring groove shape and extends along the edge of the water outlet cavity in an arc shape and extends to the filtering part. When the waste water valve is closed, after the waste water enters the water inlet cavity through the water inlet pipe, it can flow through the water inlet cavity to the filtering part and enter the first inner cavity through the filtering holes.

[0012] The utility model can be further set as: a baffle is arranged at the bottom of the water inlet cavity near the filtering part.

[0013] Through further setting, a baffle is arranged at the bottom of the water inlet cavity near the filtering part. When the waste water valve is opened, part of the waste water flowing towards the filtering holes will be blocked and restricted, which is equivalent to reducing the ratio of the waste water flowing towards the filtering holes, and further reducing the frequency of maintenance required.
