Description

Technical Field

[0001] The utility model relates to the field of sanitary ware, in particular to a flushing constant flow valve for an intelligent toilet. Background Art

[0002] The tankless toilet is a new type of water-saving toilet that does not have a water tank and uses city tap water for direct flushing. The tankless toilet eliminates the odor caused by the possible water pollution of the water tank toilet and has a good water-saving effect of more than 50%. At the same time, the tankless toilet is small in size and can effectively utilize the space of the bathroom. Therefore, the tankless toilet has been well promoted. The tankless toilet needs to be equipped with a flushing device when flushing. During use, in order to reduce the change or excess of water volume caused by the change of tap water pressure, a constant flow valve is set in the flushing device.

[0003] Existing smart toilet flush valves usually use pulse valves with fixed water holes, which have the disadvantage of large flow differences under high and low water pressure working environments. If the water hole is opened too small, the flow rate will be too small under low water pressure working environment, resulting in the toilet's sewage discharge performance failing to meet the standard; conversely, if the water hole is opened too large, the flow rate will be too large under high water pressure working environment, exceeding the flushing volume range allowed by the standard. Utility Model Content

[0004] The main purpose of the utility model is to provide a constant flow valve for flushing a smart toilet, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A flush constant flow valve for an intelligent toilet comprises a valve body and a conical valve core, wherein an installation cavity is provided in the valve body, and the conical valve core is installed in the installation cavity, wherein the conical valve core comprises a valve cap and a valve core body integrally formed with the valve cap, wherein a leakage hole is penetrated through the interior of the valve core body, an adjustment spring is sleeved on the exterior of the valve core body, the valve core body extends to the exterior of the valve body after penetrating the installation cavity of the valve body, and a water retaining plate is provided at the end of the valve core body.

[0007] Preferably, the leakage hole extends from the valve cap of the conical valve core to both sides of the upper end of the valve core body.

[0008] Preferably, the two side protrusions of the valve body are provided with card slots, and the top of the conical valve core is provided with a tenon protruding outwards to match the card slots.

[0009] Preferably, the water retaining plate is connected to the valve core body via a locking screw.

[0010] The utility model has the following beneficial effects:

[0011] Compared with the existing technology, this flushing constant flow valve can automatically adjust the size of the water hole and reduce the flow difference under high and low water pressures, so that the smart toilet can work normally under high and low water pressure environments; by reasonably designing the water retaining plate, adjusting the spring and the valve core's leakage hole and other parameters, the smart toilet can flush normally within the water pressure range of 0.1 to 0.6 MPa and meet the national standard requirements for water consumption.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-5 As shown, a flushing constant flow valve for an intelligent toilet includes a valve body 1 and a conical valve core 2, wherein an installation cavity is provided in the valve body 1, and the conical valve core 2 is installed in the installation cavity, wherein the conical valve core 2 includes a valve cap 21 and a valve core body 22 integrally formed with the valve cap 21, wherein a leakage hole 23 is penetrated inside the valve core body 22, an adjustment spring 3 is sleeved on the outside of the valve core body 22, and the valve core body 22 extends to the outside of the valve body 1 after penetrating the installation cavity of the valve body 1, and a water retaining plate 4 is provided at the end of the valve core body 22.

[0020] It should be noted that the utility model can make the smart toilet flush normally within the water pressure range of 0.1 to 0.6 MPa and meet the national standard requirements for water consumption by reasonably designing the water retaining plate 4, adjusting the spring 3 and the leakage hole 23 of the valve core.

[0021] Specifically, the leakage hole 23 extends from the valve cap 21 of the conical valve core 2 to both sides of the upper end of the valve core body 22. By adopting the above technical solution, in the high pressure state, the leakage hole 23 is connected to the water passage, which is conducive to the flow of water.

[0022] Specifically, the two sides of the valve body 1 are convexly provided with grooves 11, and the top of the conical valve core 2 is convexly provided with tenons 24 matched with the grooves 11. By adopting the above technical solution, the valve body 1 and the conical valve core 2 are easily installed.

[0023] Specifically, the water retaining plate 4 is connected to the valve core body 22 via a locking screw 5. By adopting the above technical solution, it is convenient to connect and assemble.

[0024] The utility model can be installed in the water inlet pipe of the intelligent toilet flush valve. Under the low water pressure working environment, the conical valve core 2 is in the highest position under the action of the adjusting spring 3. At this time, the water passage area between the conical valve core 2 and the valve body 1 is in the maximum state, so that the constant flow valve has a flow as large as possible under low water pressure; under the high water pressure working environment, the water retaining plate 4 pulls the conical valve core 2 to compress the adjusting spring 3, and the water passage area between the conical valve core 2 and the valve body 1 gradually becomes smaller. When the water flow is at the minimum, it can only flow through the leakage hole 23 in the middle of the conical valve core 2, so that the constant flow valve will not have an excessively large flow under high water pressure, thereby avoiding the occurrence of excessive flushing volume.

[0025] The matters not described in detail in the present invention are all known technologies to those skilled in the art.

[0026] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
