Description

Technical Field

[0001] The present invention relates to the field of sanitary wares, in particular to a waterway switching device and a toilet bowl. Background Art

[0002] Currently, when a toilet bowl is flushed, it usually involves two flushing waterways: main flushing and rim flushing. The main flushing sprays water from the main flushing waterway to mainly flush the fecal dropping point, and the rim flushing discharges water from the rim waterway and flushes around the inner side of the toilet bowl to ensure a comprehensive cleaning effect.

[0003] Existing toilet bowls flush by directly connecting to tap water and cooperating with a reversing valve. However, using tap water has the problem of unstable water pressure, which affects the flushing effect. There are also those that flush the toilet by connecting a water pump and cooperating with a reversing valve and other controls. For the used reversing valve, one type needs to rely on a motor to control the action of the reversing valve to achieve switching between different water outlet modes, and the other is a mechanical switching valve that uses water pressure to drive the movement of the valve core to achieve switching between different water outlets. It is necessary to control the power of the pump body so that the water flow pressure entering the valve body is different to control the valve core to be in different positions. In this way, it is easy to cause inaccurate retention positions of the valve core due to reasons such as aging of elastic parts or setting power errors, affecting the smooth switching of the water outlet mode, and the stability and reliability are not high enough. Summary of the Invention

[0004] The main purpose of the present invention is to overcome the defects of insufficient stability and reliability of the reversing valve in the prior art that needs to be controlled by a motor or uses a mechanical switching valve, and to provide a waterway switching device and a toilet bowl that do not require motor control, have a simple structure, and high stability and reliability.

[0046] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Specific embodiments

[0047] The present invention will be further described below through specific embodiments.

[0048] See Figures 1 to 10 , a water path switching device, including a valve body 10, a sliding member 20, an elastic member 30, etc. The valve body 10 is a hollow structure, which is provided with a cavity 11 and a water inlet 12, a first water outlet 13, and a second water outlet 14 communicating with the cavity 11. The water inlet 12, the first water outlet 13, and the second water outlet 14 are spaced apart along the axial direction of the cavity 11. The specific distribution sequence and position can be adjusted according to the situation. For example, Figure 2 the water inlet 12 and the second water outlet 14 in

[0049] are respectively located at both ends of the axial direction of the cavity 11, and the first water outlet 13 is located between the water inlet 12 and the second water outlet 14.

[0050] The sliding member 20 includes a communicating portion 21 and a sliding portion 22. The communicating portion 21 communicates with the cavity 11. One end of the communicating portion 21 is open relative to the water inlet 12, and a sealing end face 25 is provided at the other end. A through hole 26 communicating with the cavity 11 is further provided on the side close to the sealing end face 25. The sliding portion 22 is formed on the outer periphery of the communicating portion 21. An installation groove 23 for accommodating a part of the elastic member 30 is formed between the inner wall of the sliding portion 22 and the outer periphery of the communicating portion 21. For example, the elastic member 30 is a spring, and the spring is sleeved outside the communicating portion 21. One end of the spring abuts against the bottom wall of the installation groove 23, and the other end of the spring abuts against one end of the cavity 11 in the axial direction away from the water inlet 12. The elastic member 30 can also be replaced by a spring piece or other elastic structures. The outer periphery of the sliding portion 22 is slidably matched with the inner wall of the cavity 11. When the sliding portion 22 slides to the position of the water inlet 12, the sliding member 20 blocks the water inlet 12, and the first water outlet 13 and the second water outlet 14 communicate with the cavity 11. When the sliding portion 22 slides to the position of the first water outlet 13, the sliding portion 22 blocks the first water outlet 13, and the water inlet 12 and the second water outlet 14 respectively communicate with the cavity 11. When the sliding portion 22 slides to the position of the second water outlet 14, the sealing end face of the communicating portion 21 blocks the second water outlet 14, and the water inlet 12 and the first water outlet 13 respectively communicate with the cavity 11.

[0051] In this embodiment, a water inlet joint 50 is further provided at the end of the valve body 10 where the water inlet 12 is located. A blocking portion 51 is further provided on the surface of the water inlet joint 50 opposite to the sliding member 20. A channel 52 communicating with the cavity 11 is formed on the outer periphery of the blocking portion 51. When the opposite end of the communicating portion 21 of the sliding member 20 abuts against the blocking portion 51, it is blocked by the blocking portion 51, and the corresponding end of the sliding portion 22 blocks the channel 52 on the outer periphery of the blocking portion 51, thereby blocking the water inlet 12. When the opposite end of the communicating portion 21 away from the blocking portion 51, the channel 52 on the outer periphery of the blocking portion 51 is opened, and the water inlet joint 50 communicates with the water inlet 12.

[0052] A guiding structure 40 is further provided on the inner wall of the cavity 11. When the flushing water flow is input from the water inlet 12 of the valve body 10, the sliding member 20 moves circumferentially and axially along the cavity 11 under the action of the guiding structure 40 and the elastic member 30 to block the first water outlet 13 and the second water outlet 14 in sequence to realize the switching of the water outlet. The switching of the water outlet can be realized by inputting the flushing water flow. The flushing water flow refers to the water flow entering the valve body 10 when the flushing function is turned on.

[0053] Among them, see Figure 9 and Figure 10, the guiding structure 40 includes at least two guiding groove groups 41. The guiding groove groups 41 are provided with a first positioning groove 42 and a second positioning groove 43 that are axially and circumferentially spaced apart along the cavity 11. At least one guiding block 24 is provided on the outer periphery of the sliding member 20, and the guiding block 24 protrudes outward from the outer periphery of the sliding portion 22. The guiding block 24 is slidably engaged with the guiding groove group 41. When the guiding block 24 slides along the guiding groove group 41 to the first positioning groove 42 or the second positioning groove 43 when the sliding member 20 moves circumferentially and axially along the cavity 11, the sliding member 20 blocks the first water outlet 13 or the second water outlet 14 respectively. In the axial direction of the cavity 11, the arrangement order of the first positioning groove 42 and the second positioning groove 43 corresponds to the arrangement order of the first water outlet 13 and the second water outlet 14.

[0054] Further, in order to enable the guiding block 24 to smoothly move to the first positioning groove 42 and the second positioning groove 43, the guiding groove group 41 is provided with a first guiding groove 44, a second guiding groove 45 and a third guiding groove 46. The first guiding groove 44 extends obliquely along the axial direction of the cavity 11 from the water inlet 12 to the first positioning groove 42. When the flushing water flow is turned on and the water flows in and lasts for a period of time, the guiding block 24 moves along the first guiding groove 44 to the first positioning groove 42 and then stops. At this time, the first water outlet 13 is blocked and the second water outlet 14 discharges water.

[0055] The second guiding groove 45 extends obliquely along the axial direction of the cavity 11 from the first positioning groove 42 to the second positioning groove 43. One end of the third guiding groove 46 is opposite to and communicates with the first positioning groove 42, and the other end extends obliquely along the axial direction towards the end where the water inlet 12 is located and away from the first guiding groove 44. The extending directions of the second guiding groove 45 and the third guiding groove 46 are opposite. The second guiding groove 45 and the third guiding groove 46 are provided to guide the guiding block 24 from the first positioning groove 42 to smoothly move to the second guiding groove 45. When the guiding block 24 is located in the first positioning groove 42 and the flushing water flow is closed, the guiding block 24 moves to the third guiding groove 46 under the action of the elastic member 30 to open the first water outlet 13. Then, when the flushing water flow is turned on, the guiding block 24 moves to the second guiding groove 45 under the action of the water pressure. The guiding block 24 moves along the second guiding groove 45 to the second positioning groove 43 and then stops. At this time, the second water outlet 14 is blocked and the first water outlet 13 discharges water.

[0056] The guiding groove group 41 further includes a fourth guiding groove 47. The fourth guiding groove 47 is provided to guide the guiding block 24 from the second positioning groove 43 to smoothly move to the end where the water inlet 12 of the first guiding groove 44 of another adjacent guiding groove group 41 is located. Specifically, one end of the fourth guiding groove 47 communicates with the second positioning groove 43, and the other end extends axially along the cavity 11 to communicate with the end where the water inlet 12 of the first guiding groove 44 of another adjacent guiding groove group 41 is located. When the guiding block 24 is located in the second positioning groove 43 and the flushing water flow is closed, the guiding block 24 moves to the end where the water inlet 12 of the first guiding groove 44 of another adjacent guiding groove group 41 is located under the action of the elastic member 30, so as to open the second water outlet 14 and close the water inlet 12.

[0057] In the present invention, the first guiding groove 44, the first positioning groove 42, the second guiding groove 45, the second positioning groove 43, the third guiding groove 46 and the fourth guiding groove 47 are grooves having two side walls and a bottom wall or grooves having one side wall and a bottom wall. The bottom wall is the inner wall of the cavity 11, and the side walls are arc-shaped side walls or inclined planes, etc., which can be combined according to actual situations. For example, the first guiding groove 44, the first positioning groove 42 and the second positioning groove 43 are grooves having two side walls and a bottom wall, and the second guiding groove 45, the third guiding groove 46 and the fourth guiding groove 47 are grooves having one side wall and a bottom wall; the side walls of the first guiding groove 44, the second guiding groove 45 and the third guiding groove 46 are arc surfaces, and the side wall of the fourth guiding groove 47 is a plane extending axially along the cavity 11.

[0058] Furthermore, in order to better guide the moving track of the sliding member 20 in the cavity 11, the guiding structure 40 of the present invention is provided with more than two guiding groove groups 41, and the ends where the water inlets 12 of two adjacent guiding groove groups 41 are located communicate with each other; two or three guiding blocks 24 distributed at circumferential intervals are correspondingly arranged on the outer periphery of the sliding part 22 of the corresponding sliding member 20. The guiding blocks 24 slide along the corresponding guiding groove groups 41. After the guiding blocks 24 complete the sequential blocking of the first water outlet 13 and the second water outlet 14 and the flushing water flow is closed, the guiding blocks 24 enter another adjacent guiding groove group 41, and so on.

[0059] The valve body 10 of the present invention can be integrally formed. Since there is a guiding structure 40 in the cavity 11, in order to better mold, it can also be provided as a split structure assembled.

[0060] Based on this, see Figures 13 - 22, the present invention also provides a toilet, which includes a toilet body provided with a brush ring pipeline, a main flushing pipeline, a pump body, and a flushing valve. The flushing valve adopts the above-mentioned water path switching device. The toilet body can be an ordinary toilet or a smart toilet, etc. The water inlet end of the pump body is connected to the water inlet pipeline, and the water outlet end of the pump body is connected to the water inlet joint 50 of the water inlet 12 of the valve body 10. One of the first water outlet 13 and the second water outlet 14 is set as the main flushing water outlet, and the other of the first water outlet 13 and the second water outlet 14 is used as the brush ring water outlet. The main flushing water outlet is connected to the main flushing pipeline, and the brush ring water outlet is communicated with the brush ring pipeline. By controlling the opening or closing of the pump body, an intermittent flushing water flow is output, so that the sliding member 20 moves in the valve body 10 to realize the switching between brush ring water outlet and main flushing water.

[0061] In this embodiment, a nozzle 60 is also provided. The connection between the nozzle 60 and the brush ring water outlet is detachable, and the nozzle 60 of the brush ring water outlet is installed at the water outlet end of the brush ring pipeline. The detachable connection between the nozzle 60 and the brush ring water outlet is a snap connection or a threaded connection, etc. Taking the snap connection as an example, a snap member 61 is provided to realize the quick disassembly and assembly of the two. See Figure 6 and Figure 7 , the snap member 61 includes two buckle feet 62, the two buckle feet 62 form a U-shaped structure, and a buckle portion 63 is provided on the outer side of the two buckle feet 62. The buckle portion 63 has elasticity, and a convex portion 65 is further provided on the outer side of the buckle portion 63 to facilitate the quick disassembly operation. One end of the nozzle 60 is used as an insertion end and is provided with a plurality of radially penetrating mounting holes 64. The plurality of mounting holes 64 are circumferentially distributed, and a partition rib 66 is provided between adjacent mounting holes 64. Two slots 15 are provided on the outer periphery of the brush ring water outlet of the valve body 10. The two slots 15 are located on both sides of the radial direction of the brush ring water outlet diameter, and a buckle strip 16 is provided on the outer side wall of the slot 15. After the insertion end of the nozzle 60 is inserted into the brush ring water outlet, a part of the mounting hole 64 is located in the slot 15. The two buckle feet 62 of the snap member 61 are inserted through the slot 15 and the mounting hole 64, and the buckle portion 63 is buckled on the buckle strip 16 to realize quick installation; by operating the convex portion 65, the buckle portion 63 is separated from the buckle strip 16, and the snap member 61 can be pulled out to remove the nozzle 60 to realize quick disassembly.

[0062] The working principle of the device and toilet of the present invention is as follows:

[0063] In the initial state, see Figure 15 , under the action of the elastic member 30, the sliding member 20 is located at the water inlet 12. The main flushing water outlet and the brush ring water outlet are in the open state. The guide block 24 is located at the end of the first guide groove 44 close to the water inlet 12. The sliding member 20 blocks the water inlet 12 to prevent the water from flowing through the main flushing water outlet and the brush ring water outlet.

[0064] First, turn on the flushing water flow for a continuous input for a period of time. The sliding member 20 moves under the water pressure, overcoming the elastic force of the elastic member 30, until the guide block 24 slides along the first guide groove 44 to the first positioning groove 42. The sliding member 20 blocks the first water outlet 13, and the flushing water flow sprays out from the nozzle 60 of the second water outlet 14, realizing water discharge from the brush ring. See Figure 16 and Figure 17 .

[0065] Control the pump body to close and then open. When the pump body is closed, the sliding member 20 moves along the end where the water inlet 12 is located under the action of the elastic member 30, and the guide block 24 moves out of the first positioning groove 42 and moves to the third guide groove 46. When the pump body is opened, the sliding member 20 moves under the drive of the flushing water flow, and the guide block 24 moves to the second guide groove 45 until it enters the second positioning groove 43 and then stops. The sliding member 20 blocks the second water outlet 14, and the water flows out from the first water outlet 13, realizing main flushing water discharge. See Figures 18 to 20 .

[0066] After the main flushing water discharge is completed, control the pump body to close. The sliding member 20 moves along the end where the water inlet 12 is located under the action of the elastic member 30. The guide block 24 moves out of the second positioning groove 43 and moves along the fourth guide groove 47 to the end where the water inlet 12 of the first guide groove 44 connected thereto is located. The sliding member 20 returns to its initial state. See Figure 21 and Figure 22 .
