TECHNICAL FIELD
[0001] The utility model relates to the field of bathroom technology, concretely relates to a waterway switching valve suitable for intelligent toilet. BACKGROUND
[0002] The water tank of the existing intelligent toilet usually adopts a water pump to sequentially pump and discharge the water in the water tank to the circle flushing water channel and the main flushing water channel, and the position change of the outer float in the water tank is used to switch and control the water flow to be pumped to the circle flushing water channel or the main flushing water channel, that is, when the float is at a preset water level, the main flushing water channel is automatically closed by a lever switching mechanism to perform circle flushing first, and the water in the water tank is continuously pumped out, the water level is lowered, and the position of the float is also lowered to reach the preset position, and then the lever switching mechanism closes the circle flushing water channel to automatically open the main flushing water channel to discharge water, and finally, the water tank is automatically sealed and water is replenished after the water in the water tank is completely pumped out to prevent the overflow of the odor in the toilet bowl, which has a complex structure and is usually too large to occupy the internal space of the water tank, and the water storage capacity is reduced to frequently affect the flushing power of the toilet.
[0003] Therefore, the developer improves the waterway mechanism with a small volume and uses the internal float and the limiting structure to realize switching, the upper circle flushing water channel is opened (one-way opening), the float is limited and blocked in the lower main flushing water channel (one-way closing) by the water pressure linkage limiting structure of the water pump to prevent the float from moving upward due to the buoyancy, and vice versa, the lower main flushing water channel is opened, the water pump is closed to reset and unlock the linkage limiting structure, and the float moves upward due to the buoyancy to close the upper circle flushing water channel. Although this structure can solve the above problems, it still has some deficiencies: first, the structure is very complex, and the float needs to be limited by the limiting structure to realize complete switching of the two functions, and the water pump needs to be closed for subsequent switching, the water in the shell is emptied, the float loses the buoyancy and moves downward to open the upper circle flushing water channel for water replenishment or the next cycle, and the switching speed of the flushing function is slow; second, the main flushing power is inevitably insufficient, that is, due to insufficient main flushing time or small water flow, the dirt is difficult to pass over the top end of the toilet siphon, causing the dirt to flow back to the toilet bowl, and the sanitary condition is poor; third, the mute effect is poor, and the end water flow usually produces noise after the main flushing is completed, affecting the product experience.

[0039] Please refer to Figures 1 to 7 .
[0040] The embodiment provides a waterway switching valve suitable for an intelligent toilet, which is simple in structure, small in overall volume, simple in manufacturing, easy to realize and low in cost, and mainly solves the problem of slow response switching speed of main flushing and circle flushing functions of the existing toilet; the waterway switching valve body is very ingenious, which can realize the switching of circle flushing and main flushing functions by cooperating with the change of water pressure, without cooperating with the existing limiting structure (such as lever type limiting structure, flip type limiting structure) to limit and fix the float or reset unlocking action, and the response switching speed is fast, the mute effect is excellent, and the flushing potential energy is extremely strong; referring to Figure 1 and Figure 2 The waterway switching valve body mainly comprises a shell 1, a floating element 2 and a water supply assembly 4, wherein
[0041] The shell 1, referring to Figure 3It comprises a water inlet part 11, a first water outlet part 12 (for flushing or water replenishing), a second water outlet part 13 (for main flushing), and a water inlet cavity 14, wherein the second water outlet part 13 is arranged on the lower sealing shell 1a of the bottom of the shell 1; the first water outlet part 12 and the second water outlet part 13 are respectively arranged at the upper end and the lower end of the water inlet cavity 14 and are communicated with the water inlet cavity 14; the water inlet part 11 is communicated with the side of the water inlet cavity 14 and is arranged between the two water outlet parts; the design of the three parts is extremely ingenious, the water inlet part 11 is located between the two water outlet parts, when the water pump works, the water flow (water outlet direction of the water inlet part 11) can continuously impact from the right side wall surface to the left side wall surface of the inner wall of the water inlet cavity 14 to form an impact water flow, and the floating member 2 is arranged in the water inlet cavity 14 and is located below the impact water flow in the normal state, so that as long as the impact water flow is discharged from the water inlet part 11 into the water inlet cavity 14, the impact water flow will be divided into two parts, one part is directed to the first water outlet part 12 for discharge, and the other part is directed to the second water outlet part 13 to directly act on the floating member 2; and,
[0042] The floating member 2 is movably arranged in the water inlet cavity 14 and switches to open the first water outlet part 12 or the second water outlet part 13 under the action of the water flow (water buoyancy or the impact water flow); the floating member 2 comprises a blocking pressure bearing surface 21 at the upper end, a floating pressure bearing surface 22 at the lower end, and an extension part 23; when the blocking pressure bearing surface 21 or the floating pressure bearing surface 22 is acted on by the water flow (impact water flow and water buoyancy respectively), the floating member 2 moves downward in the water inlet cavity 14 to open the first water outlet part 12 or moves upward to open the second water outlet part 13; the extension part 23 is formed by extending the floating pressure bearing surface 22 towards the second water outlet part 13; the extension part 23 is inserted into or separated from the second water outlet part 13 when the floating member 2 moves in the water inlet cavity 14, and the water passing area A between the extension part 23 and the second water outlet part 13 is smaller than the water passing area B between the floating member 2 and the wall of the water inlet cavity 14 in the inserted state, and the extension part 23 will move away from the second water outlet part 13 and open it in the separated state.
[0043] In the embodiment, referring to Figure 3 and Figure 4 Because there is a certain gap water passing area A between the extension part 23 and the second water outlet part 13, the floating member 2 will not accumulate water in the normal state, and the water in the water inlet cavity 14 will be discharged from the gap, so that the floating member 2 can be positioned to the bottom of the shell 1 without any floating; and the water passing area A between the extension part 23 and the second water outlet part 13 is smaller than the water passing area B between the wall of the water inlet cavity 14, so that the water flow discharged from the water inlet cavity 14 is smaller than the water flow discharged therefrom, and when the floating member 2 needs to generate buoyancy, the water around the floating member 2 can store a certain water flow to generate buoyancy, thereby realizing the appropriate small gap drainage to ensure the positioning of the floating member 2 and storing a certain amount of water when the buoyancy is needed.
[0044] In the embodiment, referring to Figure 3 and Figure 4, when the extension part 23 is inserted into the second water outlet part 13, the water flow entering the water inlet part 11 acts on the sealing pressure surface 21 and drives the floating part 2 to displace towards the direction of the second water outlet part 13, so that the floating pressure surface 22 is limited to abut against the lower bottom wall of the shell 1. The floating pressure surface 22 extends towards the second water outlet part 13 to form a limiting baffle cover 221, and the floating pressure surface 22 is limited to abut against the lower bottom wall of the shell 1 and covers the second water outlet part 13 through the limiting baffle cover 221; at least one drainage port 221A is formed in the cover wall of the limiting baffle cover 221, and the drainage port 221A is used to guide the water flow between the inside of the limiting baffle cover 221 and the water inlet cavity 14.
[0045] In the embodiment, the limiting baffle cover 221 is used to control the water flow entering the second water outlet part 13, so as to prevent the water from the gap between the extension part 23 and the second water outlet part 13 from flowing out too fast to generate the buoyancy, and the water flow control through one drainage port 221A can be very stable.
[0046] In the embodiment, referring to Figure 4 , the second water outlet part 13 extends towards the floating part 2 to form a water blocking ring body 131, and the water blocking ring body 131 corresponds to the inner wall of the limiting baffle cover 221 to form a pressure relief space C; the pressure relief space C is used to store the water flow in the limiting baffle cover 221 after the limiting baffle cover 221 covers the second water outlet part 13, and then the water flow is stored to a height exceeding the pressure relief space C and then flows into the gap between the extension part 23 and the second water outlet part 13; in this way, even if the water flow impact force is very large, the water flow entering the pressure relief space C through the drainage port 221A can be relieved, so as to prevent the floating part 2 from shaking or yawing in the case of large water flow.
[0047] In the embodiment, referring to Figure 4 and Figure 5 , the extension part 23 includes a first water blocking section 231 and a second water blocking section 232, the first water blocking section 231 is used to be inserted into or separated from the second water outlet part 13, the second water blocking section 232 is located above the first water blocking section 231 and the water blocking ring body 131, and a drainage section 233 is formed between the second water blocking section 232 and the first water blocking section 231, and the drainage section 233 forms a water passing gap relative to the drainage wall 131a of the top outer periphery of the water blocking ring body 131; in the embodiment, the drainage section 233 and the drainage wall 131a are respectively arranged in an inclined or circular arc manner, and the two structures are mainly used to further relieve the water flow, that is, after the pressure relief space C is filled with water, the water flow can be discharged from the water passing gap, so that the water outlet is more smooth and the water pressure is also relieved.
[0048] In the embodiment, referring to Figure 6, the floating piece 2 is further provided with a quick sealing groove 24, the quick sealing groove 24 is located between the sealing pressure surface 21 and the floating pressure surface 22, the axis of the quick sealing groove 24 is parallel to the axis of the water inlet part 11, the quick sealing groove 24 is used for being impacted by the water flow entering the water inlet part 11 to drive the floating piece 2 to quickly move towards the first water outlet part 12 when the floating piece 2 is separated from the second water outlet part 13, the quick sealing groove 24 is arranged through the floating piece 2 and the water area of the quick sealing groove 24 is greater than the water area of the water inlet part 11; when the floating piece 2 is displaced towards the first water outlet part 12 under the action of the buoyancy of the internal stored water, if the buoyancy is not enough or the floating displacement speed is slower, the floating piece 2 floats to a certain height, the water flow entering from the water inlet part 11 quickly penetrates through the entire quick sealing groove 24, the quick sealing groove 24 is quickly filled, the floating piece 2 is subjected to upward force and quickly rises to close the first water outlet part 12 and completely open the second water outlet part 13, and the stored water flow in the water inlet cavity 14 for generating buoyancy is discharged from the second water outlet part 13.
[0049] In the embodiment, the guiding mechanism includes a sliding strip 31 arranged on the outer side wall of the floating piece 2 and a sliding groove 32 arranged on the inner side wall of the shell 1, the sliding strip 31 and the sliding groove 32 are respectively arranged to extend towards the first water outlet part 12 and the second water outlet part 13, when the floating piece 2 moves in the shell 1, the sliding strip 31 slides in the sliding groove 32, so that the floating piece 2 can move towards the first water outlet part 12 or the second water outlet part 13, that is, in the embodiment, the floating piece 2 floats or falls to the position under the action of the guiding of the guiding mechanism, so that the floating piece 2 is not easy to deviate and can accurately seal the first water outlet part 12 and the second water outlet part 13, secondly, the design of the guiding mechanism can ensure that the opening of the quick sealing groove 24 is accurately corresponding to the water outlet direction of the water inlet part 11, that is, the sliding groove 32 is arranged on the two side wings of the axis of the water inlet part 11, when the floating piece 2 is arranged in the sliding groove 32 through the sliding strip 31, the quick sealing groove 24 on the floating piece 2 is aligned with the water inlet part 11, and the design of the guiding mechanism can also make the entire floating piece 2 be located at the central position of the water inlet cavity 14, that is, the water area B of the entire floating piece 2 and the inner circumferential wall of the water inlet cavity 14 is kept equal.
[0050] In the embodiment, the sealing pressure surface 21 is spaced apart and recessed to form at least two air slots 211, the air slots 211 are arranged towards the first water outlet part 12, the air slots 211 are mainly used for placing a sealing ring or not arranging a sealing ring to appropriately buffer the water flow.
[0051] The working principle and use process of the utility model are as follows:
[0052] When the utility model is installed, referring to Figure 2 and Figure 3, first, the floating element 2 is installed in the water inlet cavity 14, and the sliding bar 31 on the floating element 2 is slidably installed in the sliding groove 32 on the inner wall of the water inlet cavity 14, so that the quick sealing groove 24 of the floating element 2 can be aligned with the water inlet portion 11 of the shell 1; then, the second water outlet portion 13 of the lower shell 1a is inserted and connected with the first water blocking section 231 of the floating element 2, and the entire lower shell 1a is fixedly installed at the bottom of the shell 1, thereby completing the sealing of the water inlet cavity 14 of the shell 1; finally, the water inlet portion 11 of the shell 1 is installed with the water supply assembly 4 (including a water pump not shown in the figure), the first water outlet portion 12 is connected with the flushing water pipe of the toilet bowl, and the second water outlet portion 13 is connected with the main flushing water pipe of the toilet bowl; the above waterway switching valve has a small number of structural components, and can be installed without a large number of accessories, has a high installation efficiency, and is low in cost;
[0053] After installation is completed, referring to Figures 3 to 5 , the floating element 2 in the water inlet cavity 14 is in a normal state; the floating element 2 is located at the bottom wall of the water inlet cavity 14, wherein the limiting cover 221 is in contact with the bottom wall of the water inlet cavity 14 and covers the water blocking ring body 131 and the second water outlet portion 13, the limiting cover 221 can effectively limit the insertion depth of the first water blocking section 231 into the second water outlet portion 13, that is, limit the suspension height of the first water blocking section 231 and the guide section 233, so that the first water blocking section 231 and the guide section 233 can form a gap water area relative to the second water outlet portion 13, the water area is always kept open, and as long as there is water accumulation in the water inlet cavity 14, water flow will be discharged through the water area to the second water outlet portion 13 for micro water pressure flushing, so as long as the floating element 2 is in a normal state, the floating element 2 will not be affected by any buoyancy and will not shake or move upward.
[0054] In use,
[0055] (1) referring to Figure 5 , the water supply assembly 4 is controlled to take in water from the water inlet portion 11, that is, the water pump is pressed once, and after the water flow enters, it is divided into two parts, one part flows to the first water outlet portion 12 at the upper end for continuous flushing, and the other part flows to the second water outlet portion 13 at the lower end, and the inflowing water flow is also divided into two parts, one part continuously impacts and pushes against the sealing pressure surface 21 at the top end, and in this process, the floating element 2 will not move upward and keep the first water outlet portion 12 at the upper end open for continuous flushing (without the need for a limiting structure to limit the displacement of the floating element), referring to Figure 4, another water area B between the floating element 2 and the wall of the water inlet cavity 14, and then stored to the buffer space C through the drainage port 221A. When the water level of the storage is higher than the height of the water-blocking ring body 131, the water flow enters the water area A between the extension part 23 and the second water outlet part 13 to be discharged from the second water outlet part 13. It should be noted that the water area A between the extension part 23 and the second water outlet part 13 is very small, so the main flushing pipe will only generate a little water flow to be discharged, and the discharged water flow can also increase the water flow of the flushing water flow, thereby improving the flushing strength of the flushing water flow;
[0056] (2) When the flushing of the flushing water flow is completed, the water pump is turned off. As shown in Figure 6 , the upper end of the floating element 2 loses the water pressure of the water flow of the water inlet part 11, and the lower end of the floating element 2 starts to be affected by the water floating force of the water stored in the water inlet cavity 14 to float to a certain height (for example, as shown in Figure 6 , float to a certain height, or as shown in Figure 7 , completely float to completely close the first water outlet part 12); at this time, the water pump is turned on again. As shown in Figure 7 , the water flow of the water inlet part 11 directly impacts and penetrates the fast sealing groove 24 of the floating element 2, quickly fills the fast sealing groove 24, and the fast sealing groove 24 quickly moves upward under the water pressure to completely close the first water outlet part 12 at the upper end. The first water-blocking section 231 of the floating element 2 also directly separates from the second water outlet part 13 to completely open the second water outlet part 13, and the water flow is directly discharged to the second water outlet part 13 for main flushing. The whole process is very fast, and the main flushing can quickly combine with the rotating water of the flushing water channel of the toilet bowl which has not been completely discharged, to form a more powerful water flow for flushing;
[0057] It should be noted that the floating element 2 normally floats to a certain height under the action of the water floating force to completely close the first water outlet part 12, but if the water pump is turned off and then turned on, the floating element 2 will only float to a certain height without completely closing the first water outlet part 12, as shown in Figure 6 . After the fast sealing groove 24 of the floating element 2 is impacted and filled with water flow, the floating element 2 will always close the first water outlet part 12 under the impact pressure of the water flow, and will not automatically fall and move downward under its own action. Therefore, as long as the water pump is not turned off, the second water outlet part 13 will be continuously opened;
[0058] (3) When the main flushing is completed, the water pump is turned off. As shown in Figure 5 , the fast sealing groove 24 of the floating element 2 loses the water flow pressure, and the floating element 2 moves downward under the action of its own gravity. At this time, since a certain water flow is still stored in the water inlet cavity 14, the floating element 2 can only move downward to a certain height, and cannot reach the lowest position to contact the bottom wall of the water inlet cavity 14;
[0059] Therefore, the water pump is started again, the side water flow of the water inlet part 11 enters again to generate water pressure on the sealing pressure surface 21, the linkage floating part 2 quickly drops to restore the normal state and completely open the first water outlet part 12, at this time, the last water supplement function can be performed through the brush circle water flow. Since the switching speed is fast enough, the first water outlet part 12 is quickly opened, the water supplement water flow of the first water outlet part 12 is quickly combined with the main flushing water that has not been discharged from the toilet pot surface, so that the noise at the end of the main flushing water is buffered by the water supplement water flow, preventing noise.
[0060] (4) Finally, the water pump is turned off; the accumulated water in the water inlet cavity 14 is discharged from the second water outlet part 13 through the water passing area A between the extension part 23 and the second water outlet part 13, and the floating part 2 returns to the normal state after the discharge is completed.
[0061] During the entire use process, the water flow changes by controlling the start and stop of the water pump, so that the rapid switching of each function can be completed. Therefore, the utility model breaks the disadvantages of the existing waterway switching valve structure, which is complex and requires a limiting structure component to cooperate with the float to use the main flushing and brush circle flushing function switching. The design directly discards the limiting structure component, only needs the combination of the simple shell 1 structure and the floating part 2, and the linkage floating part 2 can realize the function switching through the control of the water pressure change.
