Description

Technical Field

[0001] The invention relates to a water inlet control device with a time delay function. Background Art

[0002] In the prior art, a water inlet valve and a water inlet control device are provided in the toilet water tank. The water inlet valve supplies water to the water tank or to the outside of the water tank under the action of the water inlet control device. The water inlet control device usually includes a control unit and a water stop unit, and also includes a first water outlet channel for supplying water to the toilet water tank. The water stop unit is used to control the opening and closing of the first water outlet channel. The control unit includes a small water tank connected to the toilet water tank and a small float that floats up and down with the water level of the small water tank. The water stop unit is driven by the small float to control the opening and closing of the first water outlet channel. However, when the flow rate of water entering the small water tank is too fast or the water pressure is too high, the water level in the small water tank will rise too high, the small float will float up in advance, and the first water outlet channel will be closed in advance. That is, the water level in the water tank cannot reach the water stop level, and the water in the water inlet valve keeps flowing to the outside of the water tank, causing the water in the water inlet valve to fail to stop water.

[0041] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] Embodiment 1: (The movable member 24 cooperates with the water passage 22 to open and close)

[0043] like Figures 1 to 5 As shown, a water inlet control device with a delay function comprises:

[0044] The water inlet channel 11 is connected to the water outlet channel of the water inlet valve 2;

[0045] A first water outlet channel 12, which is connected to the water inlet channel 11 and can supply water to the toilet tank 1;

[0046] A small water tank 20, having a water storage chamber 21 and a water passage 22 connecting the water storage chamber 21 and the toilet water tank;

[0047] A water stopping unit, comprising a small float 30, which floats up or down with the water level in the water storage chamber 21 to control the opening and closing of the first water outlet channel 12;

[0048] A control unit, when water enters the water inlet channel 11 and the first water outlet channel 12 is opened, the control unit controls the small float 30 to remain in a falling state under the water pressure of the first water outlet channel 12, thereby keeping the first water outlet channel 12 open; after the water inlet channel 11 stops flowing, the control unit is reset, and the small float 30 floats up with the water level of the water storage chamber 21, thereby closing the first water outlet channel 12.

[0049] In this embodiment, the water inlet valve 2 is a water tank inlet valve with a float control assembly. The float control assembly floats or falls with the water level of the toilet water tank 1, thereby controlling the closing and opening of the water inlet valve 2. The structure of the water inlet valve 2 adopts the existing water tank inlet valve, which is the prior art and will not be repeated here.

[0050] In this embodiment, a second water outlet channel 13 is also included, and the water stop unit also includes a water stop component 40 for controlling the opening and closing of the first water outlet channel 12 and a valve core 50 for controlling the opening and closing of the second water outlet channel 13. The small float 30 falls or floats up to drive the water stop component to open or close the first water outlet channel 12, and when the small float 30 falls and drives the water stop component 40 to open the first water outlet channel 12, the valve core 50 closes the second water outlet channel 13; when the small float 30 floats up and drives the water stop component 40 to close the first water outlet channel 12, the valve core 50 opens the second water outlet channel 13 under the action of the water pressure of the water inlet channel 11. Specifically, the water inlet control device includes a valve body 10, and the water inlet channel 11, the first water outlet channel and the second water outlet channel are all arranged on the valve body 10, and the water stop unit is movably mounted on the valve body 10.

[0051] In this embodiment, an elastic member 60 is further included to provide elastic force to the valve core 50 , so that the valve core 50 can be reset and close the second water outlet channel 13 under the action of the elastic member 60 .

[0052] In this embodiment, an elastic member 60 is further included to provide elastic force to the valve core 50 , or the valve core 50 is an elastic body having elastic force itself.

[0053] In this embodiment, the first water outlet channel 12 and / or the second water outlet channel 13 is a flow-increasing channel. Specifically, the second water outlet channel 13 is a flow-increasing channel. The valve body 10 is provided with a nozzle 14 and a nozzle 15. The nozzle 14 and the nozzle 15 are clearance-matched. When water flows out of the second water outlet channel 13, a Venturi effect is formed in the process of the nozzle 14 spraying water at high speed toward the nozzle 15.

[0054] In this embodiment, the second water outlet channel 13 supplies water to the toilet flushing water channel.

[0055] In this embodiment, the control unit includes a control channel 23 connected to the first water outlet channel 12, and also includes a movable part 24 movably arranged on the control channel 23. When the water inlet channel 11 is filled with water and the first water outlet channel 12 is opened, the movable part 24 moves to the first position under the action of the water pressure of the control channel 23. After the water inlet channel 11 stops water, the movable part 24 moves to the second position.

[0056] In this embodiment, the movable member 24 cooperates with the water passage 22 to open and close. When the movable member 24 moves to the first position, the movable member 24 closes the water passage 22. When the movable member 24 moves to the second position, the movable member 24 opens the water passage 22.

[0057] In this embodiment, an elastic element 25 is further included to provide elastic restoring force to the movable part 24. After the water inlet channel 11 stops water, the movable part 24 moves to the second position under the action of the elastic element 25. Specifically, the elastic element 25 is a restoring spring.

[0058] In other embodiments, the first water outlet channel 12 and the second water outlet channel 13 can also be swapped, that is, the opening and closing of the second water outlet channel 13 is controlled by the water stop component 40, and the opening and closing of the first water outlet channel 12 is controlled by the valve core 50. Specifically, the second water outlet channel 13 is also included, and the water stop unit includes a water stop component 40 for controlling the opening and closing of the second water outlet channel 13 and a valve core 50 for controlling the opening and closing of the first water outlet channel 12. The small float 30 falls or floats to drive the water stop component 40 to close or open the second water outlet channel 13, and when the small float 30 falls and drives the water stop component 40 to close the second water outlet channel 13, the valve core 50 opens the first water outlet channel 12 under the water pressure of the water inlet channel 11; when the small float 30 floats and drives the water stop component 40 to open the second water outlet channel 13, the valve core 50 closes the first water outlet channel 12.

[0059] The specific working process of this embodiment is:

[0060] like Figure 2 and Figure 3 As shown, when the small float 30 is in the floating position, the water stop assembly 40 closes the first water outlet channel 12. At this time, the movable member 24 is in the second position under the action of the elastic element 25 to open the water passage 22. The valve core 50 overcomes the elastic force of the elastic member 60 under the water pressure of the water inlet channel 11 and then opens the second water outlet channel 13, so that the water inlet channel 11 is connected with the second water outlet channel 13. The water in the second water outlet channel 13 forms an increased flow water under the cooperation of the nozzle 14 and the nozzle 15 and is sprayed to the toilet brush ring water channel to flush the inner wall of the toilet bowl.

[0061] like Figure 4 and Figure 5 As shown, when the small float 30 is in the falling position, the small float 30 drives the water stop assembly 40 to open the first water outlet channel 12, and the valve core 50 is reset under the action of the elastic member 60 to close the second water outlet channel 13, so that the water inlet channel 11 is connected with the first water outlet channel 12. At the same time, the movable member 24 moves to the first position under the water pressure of the first water outlet channel 12, closing the water passage 22, so that the water in the toilet tank 1 cannot enter the small water tank 20, thereby making the small float 30 Keeping in the falling state, the water in the first water outlet channel 12 flows to the toilet water tank 1. When the water level in the toilet water tank 1 rises to the water stop level, the water inlet valve 2 stops water. At this time, the movable part 24 loses the water inlet pressure of the first water outlet channel 12 and moves to the second position under the action of the elastic element 25. The water passage 22 opens, and the water in the toilet water tank 1 enters the small water tank 20. The small float 30 rises to the floating position with the water level of the small water tank 20, thereby controlling the water stop assembly 40 to close the first water outlet channel 12.

[0062] Embodiment 2: (Moving member 24 and small floating bucket 30 limit or give way to each other)

[0063] like Figure 6 and Figure 7 As shown, the main difference between this embodiment and the above-mentioned embodiment is that, in this embodiment, the movable part 24' and the small float 30' are limited or given way to each other. When the movable part 24' moves to the first position, the movable part 24' limits the small float 30' at the falling position. When the movable part 24' moves to the second position, the movable part 24' releases the limitation on the small float 30'. Specifically, the small float 30' has a connecting arm 31' extending downward, and the movable part 24' has a convex rib 241' extending outward. When the movable part 24' moves to the first position, the convex rib 241' of the movable part 24' abuts against the connecting arm 31' to limit the position.

[0064] Other undescribed parts are consistent with the above embodiments and will not be described again here.

[0065] The above description shows and describes the preferred embodiments of the present invention. As mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field.
