Description

Technical Field

[0001] The utility model relates to the technical field of flushing devices, in particular to a voltage stabilizing device, a flushing device and a toilet bowl. Background Art

[0002] Common toilet bowls are configured with a function of flushing the brush ring. When directly using the tap water source for flushing the brush ring, there is an easy contradiction between low-pressure flushing and high-pressure splash prevention. Specifically, the tap water pressure has a large variation range. At low water pressure, due to the small flow rate and slow velocity, the brush ring water flow ejected is difficult to cover the entire brush ring, resulting in incomplete cleaning of the pot surface; to ensure complete cleaning of the pot surface, generally, the water pressure is increased to solve the problem. However, when using a high-pressure brush ring water flow, it is more likely to have the problem of water splashing outside the brush ring, and the greater the water pressure, the more serious the splashing, which is likely to cause a poor user experience. Summary of the Utility Model

[0003] Aiming at the deficiencies in the background art, the purpose of the utility model is to provide a voltage stabilizing device, a flushing device and a toilet bowl.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A voltage stabilizing device includes a body. The body is provided with an outlet channel. An adjustable voltage stabilizing member is arranged in the outlet channel. The voltage stabilizing member divides the outlet channel into an inlet chamber and an outlet chamber. The voltage stabilizing member is provided with a constant flow channel. The gap between the voltage stabilizing member and the body forms a current limiting channel. The constant flow channel and the current limiting channel communicate the inlet chamber and the outlet chamber;

[0006] It further includes a reset member, which is arranged between the voltage stabilizing member and the body;

[0007] The voltage stabilizing member is driven by a water flow with a water pressure greater than the reset force generated by the reset member, so as to adjust the cross-sectional area of the current limiting channel. When the water pressure of the water flow is less than the reset force, the reset member enables the voltage stabilizing member to move and reset in the opposite direction of the outlet direction.

[0008] Further, the gap between the voltage stabilizing member and the outlet channel in the radial direction forms a communication channel, and the gap between the voltage stabilizing member and the outlet channel in the axial direction forms a current limiting channel. The inlet chamber, the communication channel, the current limiting channel and the outlet chamber are sequentially communicated along the outlet direction.

[0009] Further, the voltage stabilizing member includes a bracket. The bracket is provided with a current limiter. The gap between the bracket and the body in the radial direction forms a communication channel, and the gap between the bracket and the body in the axial direction forms a current limiting channel. The current limiter is provided with a constant flow channel.

[0010] Further, a guide post is provided in the water outlet cavity. The bracket includes a mounting frame and a guide plate connected to one side of the mounting frame. The flow restrictor is installed on the mounting frame. The gap between the mounting frame and the guide plate forms a first flow passage. The first flow passage communicates with the communication passage and the water outlet cavity. The guide plate is movably sleeved outside the guide post. The gap between the end face of the guide post and the mounting frame forms a flow limiting passage.

[0011] Further, it further includes an adapter. One end of the adapter is connected to the side of the body where the water inlet cavity is provided, and the other end of the adapter is connected to the water outlet device.

[0012] Further, a locking cover is provided in the water inlet cavity. The adapter presses the locking cover against the body. The locking cover is provided with a plurality of second flow passages communicating with the water inlet cavity. And when the water flow pressure is less than the reset force magnitude, the voltage stabilizing member abuts against the locking cover.

[0013] A flushing device includes a valve body. The valve body is provided with a water inlet and a first water outlet communicating with the water inlet. A voltage stabilizing device as described above is provided at the first water outlet. [[ID=??]] [[ID=??]]

[0014] Further, the valve body is further provided with a second water outlet communicating with the water inlet.

[0015] Further, the valve body includes a main valve body and a first sub-valve body and a second sub-valve body arranged on both sides of the main valve body. The main valve body is provided with a water inlet. The first sub-valve body is provided with a first water outlet. The second sub-valve body is provided with a second water outlet.

[0016] A toilet includes a ceramic body. The ceramic body is provided with a brush ring water outlet and a jet water outlet. It includes a flushing device as described above.

If these tags have specific meanings or need to be processed in a certain way, please provide more detailed information.1. A voltage stabilizing device proposed by the present utility model includes a body. The body is provided with a water outlet channel. Inside the water outlet channel, there is a movable voltage stabilizing member and a reset member arranged between the voltage stabilizing member and the body. A current limiting channel is arranged between the voltage stabilizing member and the body, and the voltage stabilizing member is provided with a constant current channel. Both the current limiting channel and the constant current channel are connected to the water inlet cavity and the water outlet cavity. When in use, when the water pressure is lower than the reset force generated by the reset member, the voltage stabilizing member does not move, and the water passing area of the current limiting channel does not change. The voltage stabilizing device continuously discharges water in the maximum flow state. When the water pressure is higher than the reset force generated by the reset member, the water flow drives the voltage stabilizing member to move along the water outlet direction, thereby reducing the water passing area of the current limiting channel and reducing the water outlet flow of the voltage stabilizing device. Moreover, the water passing area of the constant current channel is not affected by the water pressure, and it always connects the water inlet cavity and the water outlet cavity, ensuring that when the water pressure is too high and the current limiting channel is completely closed, the voltage stabilizing device still discharges water normally, ensuring that the voltage stabilizing device stabilizes the current and limits the flow under high water pressure without affecting the water outlet flow under low water pressure, and avoiding the situation of water flow splashing under high water pressure, thereby improving the user experience.

[0019] 2. A voltage stabilizing device proposed by the present utility model. The water outlet cavity is provided with a guide post, and one end of the bracket is movably sleeved outside the guide post to ensure the movement of the bracket in the axial direction.

[0020] 3. A voltage stabilizing device proposed by the present utility model. A locking cover is arranged in the water inlet cavity. When the water flow pressure is less than the reset force, the bracket abuts against the locking cover, avoiding the voltage stabilizing member compressing the space of the water inlet cavity under the action of the reset member, ensuring that there is an appropriate water inlet space in the water inlet cavity, and at the same time avoiding the bracket disengaging from the guide post.

[0021] 4. A flushing device proposed by the present utility model includes a valve body. The valve body is provided with a water inlet and a first water outlet connected to the water inlet. A voltage stabilizing device is arranged at the first water outlet to avoid the situation of water flow splashing under high water pressure.

[0022] 5. A flushing device proposed by the present utility model. The valve body is further provided with a second water outlet connected to the water inlet. The second water outlet is not provided with a voltage stabilizing device to meet the user's usage requirements of low water pressure and low flow, and high water pressure and high flow.

[0023] 6. A toilet proposed by the present utility model includes the flushing device described above. Among them, the water outlet of the voltage stabilizing device is connected to the brush ring water outlet, reducing the situation of water flow splashing at the brush ring water outlet under high water pressure while ensuring the cleaning effect of the pot surface. At the same time, the second water outlet is connected to the jet water outlet, and the voltage stabilization and current limiting of the first water outlet do not affect the second water outlet, thereby ensuring the high-pressure jet of the jet water outlet and facilitating the formation of a siphon effect to improve the sewage discharge performance.

Detailed implementation mode

[0035] Embodiment 1

[0036] The following combines Figures 1-4 to describe this embodiment in detail.

[0037] A voltage stabilizing device 50 includes a body 60. The body 60 is provided with a water outlet channel. A movable voltage stabilizing member is arranged in the water outlet channel. The voltage stabilizing member divides the water outlet channel into a water inlet chamber 301 and a water outlet chamber 302. The voltage stabilizing member is provided with a constant flow channel. The gap between the voltage stabilizing member and the body 60 forms a flow limiting channel 402. Both the constant flow channel and the flow limiting channel 402 communicate the water inlet chamber 301 and the water outlet chamber 302;

[0038] It further includes a reset member 90. The reset member 90 is arranged between the voltage stabilizing member and the body 60. The reset member 90 generally adopts a compression spring;

[0039] The voltage stabilizing member is driven by a water flow whose water pressure is greater than the reset force generated by the reset member 90, so as to reduce the cross-sectional area of the flow limiting channel 402. When the water pressure of the water flow is less than the reset force, the reset member 90 enables the voltage stabilizing member to move and reset in the opposite direction of the water outlet direction.

[0040] In this embodiment, as Figure 2 shown, the voltage stabilizing member divides the water outlet channel into a water inlet chamber 301 and a water outlet chamber 302. The gap between the voltage stabilizing member and the body 60 in the radial direction forms a communication channel 401. The gap between the voltage stabilizing member and the body 60 in the axial direction forms a flow limiting channel 402. And the water inlet chamber 301, the communication channel 401, the flow limiting channel 402 and the water outlet chamber 302 are sequentially communicated along the water flow direction.

[0041] In this embodiment, the voltage stabilizing component is provided with a constant current channel (not shown), and the constant current channel communicates with the water inlet cavity 301 and the water outlet cavity 302. The voltage stabilizing component includes a bracket 70, the bracket 70 is provided with a current limiter 80, the gap between the bracket 70 and the body 60 in the radial direction forms a communication channel 401, the gap between the bracket 70 and the body 60 in the axial direction forms a current limiting channel 402, and the current limiter 80 is provided with a constant current channel. Further, the water outlet cavity 302 is provided with a guide post 601, and one end of the bracket 70 is movably sleeved outside the guide post 601 to ensure that the bracket 70 moves in the axial direction. The bracket 70 is also provided with a first flow passage 1401 that communicates the communication channel 401 and the water outlet cavity 302.

[0042] In this embodiment, the water outlet cavity 302 is provided with a guide post 601, the bracket 70 includes a mounting frame 701 and a guide plate 702 connected to one side of the mounting frame 701, the current limiter 80 is installed on the mounting frame 701, the gap between the mounting frame 701 and the guide plate 702 forms a first flow passage 1401, the first flow passage 1401 communicates with the communication passage and the water outlet cavity 302, the guide plate 702 is provided with a guide hole 7021 to be movably sleeved outside the guide post 601, and the gap between the end face of the guide post 601 and the mounting frame 701 forms a current limiting channel 402. A first connecting convex portion 1001 is provided on one side of the mounting frame 701 facing the guide plate 702, a second connecting convex portion 1002 is provided on one side of the body 60 facing the mounting frame 701, and both ends of the reset member 90 are respectively connected to the first connecting convex portion 1001 and the second connecting convex portion 1002. Further, a sealing gasket 110 is sleeved outside the first connecting convex portion 1001, and when the current limiting channel 402 is completely closed, the upper end face of the guide post 601 is sealingly abutted against the sealing gasket 110.

[0043] During use, when the water pressure is low, that is, the impact force of the water flow acting on the bracket 70 is less than the restoring force generated by the reset member 90, the bracket 70 does not move, that is, the water passing area of the current limiting channel 402 does not change, as Figure 5 shown; when the water pressure is high, that is, the impact force of the water flow acting on the bracket 70 is greater than the restoring force generated by the reset member 90, the bracket 70 moves along the water flow. At this time, the guide post 601 extends into the first flow passage 1401, the distance between the upper end face of the guide post 601 and the top surface of the first flow passage 1401 becomes smaller, the water passing area of the first flow passage 1401 decreases, that is, the water passing area of the current limiting channel 402 decreases, thereby restricting the flow rate of the first water outlet 202 and controlling the flow direction of the first water outlet 202 within 13 L / min. Further, when the water pressure is much greater than the restoring force generated by the reset member 90, the upper end face of the guide post 601 abuts against the sealing gasket 110, so that the current limiting channel 402 is completely closed, as Figure 6 shown. At this time, the water flow flows from the water inlet cavity 301 through the constant current channel into the water outlet cavity 302, thereby ensuring the normal water outlet of the first water outlet 202.

[0044] In this embodiment, an adapter 120 is also included, one end of which is connected to the main body 60, and the other end of which is connected to the water outlet device. The adapter 120 is connected to the main body 60 and the first water outlet 202 by a threaded connection, or other connection methods such as a snap connection. Furthermore, a locking cover 130 is provided in the water inlet chamber 301, and the adapter 120 presses the locking cover 130 against the main body 60. The locking cover 130 is provided with a plurality of second flow channels 1402 connected to the water inlet chamber 301, and when the water pressure is less than the reset force, the bracket 70 abuts against the locking cover 130 to prevent the pressure stabilizer from compressing the space of the water inlet chamber 301 under the action of the reset member 90, thereby ensuring that there is an appropriate water inlet space in the water inlet chamber 301 and preventing the bracket 70 from detaching from the guide column 601.

[0045] This embodiment proposes a voltage stabilizing device 50, and the voltage stabilizing principle is as follows:

[0046] When the water pressure is lower than the reset force generated by the reset member 90, the pressure stabilizing member does not move, and the water flow area of the flow-limiting channel 402 does not change, so that the pressure stabilizing device 50 continues to discharge water at the maximum flow rate; when the water pressure is higher than the reset force generated by the reset member 90, the water flow drives the pressure stabilizing member to move in the water outlet direction, thereby reducing the water flow area of the flow-limiting channel 402 and reducing the water flow rate of the pressure stabilizing device 50. At the same time, the water flow area of the constant flow channel is not affected by the water pressure, and it is always connected to the water inlet chamber 301 and the water outlet chamber 302, ensuring that when the water pressure is too high and the flow-limiting channel 402 is completely closed, the pressure stabilizing device 50 still discharges water normally, ensuring that the pressure stabilizing device 50 stabilizes and limits the high water pressure without affecting the low water pressure water flow rate, avoiding the splashing of the high water pressure water flow, thereby improving the user experience.

Furthermore, the valve body 10 is provided with a second water outlet 203 connected to the water inlet 201. The second water outlet 203 is not provided with the pressure stabilizing device 50, thereby meeting the user's needs for low water pressure and low flow, as well as high water pressure and high flow.

[0050] In this embodiment, the valve body 10 includes a main valve body 101, a first sub-valve body 102 and a second sub-valve body 103 arranged on both sides of the main valve body 101.

On the premise of ensuring the cleaning effect of the pot surface, the situation of water splashing at the brush ring water outlet under the state of high-pressure water pressure is reduced. At the same time, the second water outlet 203 is communicated with a jet nozzle through a jet pipeline 1703.
