Description

Technical Field

[0001] This utility model relates to the field of drain valve technology, and in particular to a valve seat assembly, a drain valve, and a toilet. Background Technology

[0002] In toilet drainage systems, optimizing the drainage rate is crucial, as a higher drainage rate typically translates to stronger flushing power. However, most toilets on the market currently have a fixed and non-adjustable drainage rate. Given the wide variety of toilet types, different models have varying requirements for the drainage rate of their flushing valves. Toilets with larger pipes and volumes require a higher drainage rate to achieve effective flushing. Conversely, for smaller toilets with smaller pipe sizes, an excessively high drainage rate can lead to increased water flow speed and lift height, resulting in splashing water and increased noise. This splashing water can not only get on the user or the floor but also cause inconvenience and annoyance. Utility Model Content

Detailed Implementation

[0035] Example 1

[0036] The following is combined Figures 1-8 This utility model will be described in detail.

[0037] A valve seat assembly includes a valve seat body 10 and an adjusting member 20, specifically,

[0038] The valve seat body 10 is provided with a drain chamber 101, and the bottom of the valve seat body 10 is provided with a water outlet 102 communicating with the drain chamber 101. The side of the valve seat body 10 is provided with a plurality of water inlets 103 communicating with the drain chamber 101. A plurality of first engaging portions 501 are provided along the height direction of the valve seat body 10; and...

[0039] The adjusting member 20 is provided with a second snap-fit ​​part 502, which can be detachably snapped onto any of the first snap-fit ​​parts 501, so that the adjusting member 20 can move up and down to change the flow area of ​​the inlet 103, thereby adjusting the drainage speed to adapt to drainage pipes of different sizes and improving the user experience.

[0040] like Figure 1 As shown, when the adjusting member 20 is engaged with the first engaging part 501 at its highest position, the inlet 103 has the largest flow area, resulting in the fastest drainage speed; Figure 2 As shown, the adjusting member 20 is snapped into another first snap-fit ​​part 501, the flow area of ​​the water inlet 103 is reduced, and the corresponding drainage speed is also reduced.

[0041] like Figure 5 As shown, the outer side of the valve seat body 10 is provided with a first snap-fit ​​portion 501, and the inner side of the adjusting member 20 is provided with a second snap-fit ​​portion 502. The adjusting member 20 is sleeved on the outer side of the valve seat body 10, so that there is a symmetrical locking force between the adjusting member 20 and the valve seat body 10, ensuring a stable connection between the adjusting member 20 and the valve seat body 10.

[0042] like Figure 4 and Figure 6 As shown, the outer side of the valve seat body 10 is provided with a plurality of spaced protrusions 104, and the grooves between each protrusion 104 form the first engaging portion 501; as Figure 7 and Figure 8 As shown, the inner side of the adjusting member 20 has a locking protrusion extending circumferentially, which constitutes the second engaging part 502. The inner side of the adjusting member 20 has a limiting part 201, which abuts against the protrusion 104 to limit the rotation angle of the adjusting member 20, preventing excessive rotation and facilitating the engagement of the first engaging part 501 and the second engaging part 502. The opposing inner side of the adjusting member 20 has a relief groove 202 arranged axially, in which the locking protrusion is located. The relief groove 202 has an inlet 203 for the protrusion 104 to slide into, and the locking protrusion is inserted into the corresponding groove by rotating the adjusting member 20.

[0043] like Figure 8 As shown, the first end of the locking protrusion is connected to the first sidewall of the relief groove 202, and the first sidewall forms the limiting part 201. The gap between the second end of the first locking protrusion and the second sidewall of the relief groove 202 forms the inlet 203. The relief groove 202 is provided with an anti-disengagement protrusion 204 that protrudes radially inward along the adjusting member 20. The space enclosed by the anti-disengagement protrusion 204, the locking protrusion, and the sidewall of the relief groove 202 forms the locking space 205 for the locking protrusion 104.

[0044] like Figure 5 As shown, the outer facade of the adjusting member 20 is provided with a first mark 30 and a second mark 40. The first mark 30 is used to indicate the rotation direction of the adjusting member 20 for unlocking and locking, and the second mark 40 is used to indicate the movement direction of the adjusting member 20 when increasing and decreasing the water inlet 103, so as to facilitate the user to operate the adjusting member 20.

[0045] The valve seat assembly proposed in this embodiment is composed of... Figure 1 The status shown has changed to Figure 2 The following is an example using the state shown as an example. The specific method is as follows:

[0046] When the valve seat assembly is in Figure 1 In the indicated state, the inlet 103 has the largest flow area. Rotate the adjusting member 20 in the unlocking direction (clockwise) to disengage the protrusion 104 from the locking space 205, disengaging the locking protrusion from the groove. Then move the adjusting member 20 downwards. When the adjusting member 20 reaches the appropriate position, rotate it in the locking direction (counterclockwise) to position the protrusion in the locking space 205, inserting the locking protrusion into the groove. This reduces the flow area of ​​the inlet 103. Figure 2 As shown.

[0047] Example 2

[0048] A drain valve, such as Figure 9 As shown, the device includes a drainage body 60, which has a valve cover 601 and a control mechanism 602 for controlling the movement of the valve cover 601. It also includes a valve seat assembly as described above. The drainage body 60 is connected to the valve seat body 10, and the valve cover 601 covers the outlet 102. The valve seat body 10 has a snap-fit ​​groove 105, and the drainage body 60 has a snap-fit ​​protrusion 603 that engages with the snap-fit ​​groove 105.

[0049] Compared to the prior art, which drives the adjusting component 20 by rotating the drain body 60 to change the flow area of ​​the inlet 103, this drain valve directly drives the adjusting component 20. This eliminates the problem that the drain button may not be able to match after the drain body 60 is rotated, which is a problem that may occur in the prior art. Furthermore, the prior art requires modification of the drain body 60, while this valve seat assembly can be adapted to the existing drain body 60 without modification. This results in low implementation cost and wide applicability.

[0050] Example 3

[0051] A toilet includes a toilet body with a water tank and a drain valve installed at the drain outlet of the water tank for opening and closing the drain outlet.
