Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bathroom production, concretely relates to a flushing water supply control valve and a toilet flushing assembly for no electricity state. BACKGROUND

[0002] At present, the existing intelligent toilet, because the water tank is generally lower than the intelligent cover plate, has no potential for flushing, so it is necessary to install a water pump to sequentially pump the water in the low water level water tank to the circle flushing channel and the main flushing channel for flushing, and the flushing time and water volume of the circle flushing channel and the main flushing channel are realized by the cooperation of the water inlet float bucket and the switching structure, after pumping water by the water pump, the water level of the water tank drops, and after dropping to the position set by human, the main flushing channel is switched on, when the water level drops to the bottom, the water tank is replenished until the water level of the water tank returns to the original position, that is, the circle flushing channel is switched to the original state.

[0003] The above-mentioned mode is the most common structure, which realizes water inlet and switching by using water level change, but the structure is large in size, and needs to rely on the water inlet float bucket as a driving part, if the water inlet float bucket is affected by scale and other factors and is jammed, the lifting is not smooth, and the switching cannot be realized, and the stability is poor; in addition, due to the large size, the water tank space is large, the water storage capacity of the water tank is insufficient, the dirt is difficult to flush clean during flushing, and the float bucket is limited by the switching structure and must be lowered to the lowest water level to be replenished, otherwise the main flushing channel cannot complete flushing; finally, the water volume is insufficient and cannot be flushed clean, and the water cannot be replenished;

[0004] Therefore, the researchers develop a switching structure that does not rely on external water inlet float bucket to realize switching, the advantage of this mode over the common structure is that the size is reduced, the switching is realized without relying on the water inlet float bucket, so that the water inlet float bucket can be replenished without the lowest position, and the water in the water tank can be quickly replenished while being discharged; but this switching structure needs to rely on the on-off of the water pump to realize the switching of the circle flushing channel and the main flushing channel, and relies on the change of water inlet pressure to realize the switching, otherwise the whole switching structure cannot be used;

[0005] This also means that in the power-off / no electricity state, the flushing system of the toilet is completely paralyzed and cannot be used normally, which seriously affects the experience of the user (it is easy to be misjudged by the consumer as a product damage, which belongs to a low-quality and fake product); further, how to realize smooth and potential water inlet in the no electricity state, sequentially realize the water outlet of the circle flushing channel and the main flushing channel, control the water outlet time (water volume) of the two channels, and have small size and do not occupy space, a series of difficulties need to be further researched and improved to be solved at the same time.

[0024] From the above description of the utility model, relative to the prior art, the utility model has the following beneficial effects:

[0025] The flushing water supply control valve breaks the disadvantage that the traditional mechanical valve and the electric control valve cannot be used together, and can still realize the flushing function in the non-electric state; the flushing function here is not a simple on-off flushing function, but a flushing function and effect with the following multiple effects, which are as follows:

[0026] Firstly, one-key opening (one-time pressing) can open the sequential flushing, that is, only one pressing can realize the sequential flushing of the brushing water channel and the main flushing channel, and multiple pressings are not needed, so the experience is good;

[0027] Secondly, on the basis of one key pressing, the flushing time (i.e. control the water amount) can be controlled well, after the switch assembly is opened, the water flow impacts the movable valve sleeve in the pressure chamber to the chamber bottom, and then quickly closes the communication between the water inlet part and the pressure chamber, at this time, the water flow in the pressure chamber flows out from the drain channel, and slowly extrudes the water flow in the chamber under the action of the first elastic member, in this process, the movable valve sleeve slowly rises, the upper acting surface cooperates with the elastic switching structure to open the channel, and then the sealing assembly is opened, the water flow flows out from the water outlet part, and then the flushing of the circle flushing channel is realized; with the rising of the movable valve sleeve, the elastic switching structure is closed under the position change of the acting surface, at this time, the waterway switching valve changes position, and switches to the main flushing channel water outlet; and with the continuous rising of the movable valve sleeve, the elastic switching structure changes the channel opening again, and then the water outlet part is opened again, and then the main flushing channel is supplied with water; a very important improvement point here is that the flushing time and water amount of the whole circle flushing channel and the main flushing channel are set according to the position change of the movable valve sleeve, and the elasticity of the first elastic member dominates the speed of the position change of the movable valve sleeve, the elasticity of the first elastic member is relatively constant and stable, the control of the whole flushing time is very uniform, and the flushing time and water amount of the circle flushing channel and the main flushing channel are not different each time, which cannot be realized in the existing structure, because the existing structure is based on water pressure, and the water pressure is in a state of continuous fluctuation, the flushing time is long when the water pressure is large, the flushing time is short when the water pressure is small, and it is impossible to quantify and guarantee constant time, and the experience of the user is very poor, the intermittent opening and closing of the mode described in the utility model is not related to the water inlet pressure, and is constant control, and the flushing time (water amount) is set to be nearly uniform each time.

[0028] Furthermore, the whole structure has small volume and does not need to use the water inlet float bucket part for operation.

[0029] In summary, the flushing control valve can realize one-key control, sequence flushing of the circle flushing channel and the main flushing channel, constant control of the flushing time and water amount each time, smooth use in the power-off state, and good experience, and the whole product design idea and structure are very ingenious.

[0057] In addition, the elastic switching structure 24 in the embodiment includes the movable frame 242, the abutting member 241 and the second elastic member 243;

[0058] The movable frame 242 is swingably arranged in the base 12 through the hinge part 242A arranged thereon, and is used to open and close the channel 21A on one side and is used to act between the adjusting seat 21 and the movable valve sleeve 22 through the abutting member 241 and the second elastic member 243 on the other side, so that the abutting member 241 abuts against the action surface 221; that is, the movable frame 242 is arranged on the adjusting seat 21 through the lever principle; wherein the movable valve sleeve 22 moves along the pressure chamber 16, the inner wall of the movable valve sleeve 22 is in contact with the abutting member 241 through the wave-shaped action surface 221, and swings (the lever swings) along the position change of the action surface 221 to open or close the channel 21A by the movable frame 242.

[0059] The sealing assembly 3 is opened and closed by the pressure change of the pressure chamber 16 to open and close the water inlet of the water outlet part 15;

[0060] The sealing assembly 3 comprises a sealing lip 32 covering the water inlet of the water outlet part 15; the adjusting seat 21 and the water outlet part 15 are separated by the sealing lip 32 to form a first pressure stabilizing cavity 31, which is communicated with the channel 21A of the adjusting seat 21; wherein the sealing lip 32 is provided with a drainage hole 32A, which is communicated with the first pressure stabilizing cavity 31 and the water inlet part 14; the water outlet part 15 is sealed by the first pressure stabilizing cavity 31; the pressures on both sides of the sealing lip 32 are the same in the static pressure state, so that the water outlet part 15 can be stably sealed.

[0061] The switch assembly 4 is arranged in the shell 11 and is used for opening and closing the communication between the water inlet part 14 and the pressure cavity 16.

[0062] The switch assembly 4 comprises a sealing diaphragm 41, a second pressure stabilizing cavity 42 and a driving group 43.

[0063] The sealing diaphragm 41 is arranged in the auxiliary cavity 17 and covers the inlet of the pressure cavity 16, and is provided with a water passing hole B communicated with the water inlet part 14 and the second pressure stabilizing cavity 42.

[0064] The driving group 43 is driven by external force to open and close the water passing hole B, so as to change the pressures on both sides of the sealing diaphragm 41, so that the water inlet part 14 and the pressure cavity 16 are communicated or closed; the driving group 43 in the embodiment comprises a connecting rod 431, a third elastic member 432 and a deformation member 433; one end of the connecting rod 431 is used for opening and closing the water passing hole B, and the other end is connected with the deformation member 433; the deformation member 433 moves to the water passing hole B direction by the action of air pressure, and drives the connecting rod 431 to open the water passing hole B, so as to change the pressures on both sides of the sealing diaphragm 41; wherein the elastic member is used for driving the connecting rod 431 to reset to seal the water passing hole B; the flow discharge channel 18 is communicated with the water passing hole B.

[0065] Further comprising an air pressure switch (not shown in the figure), which is arranged outside the water tank, is sealedly connected with the shell 11 through the air pipe, and is acted on the deformation member 433 through air pressure.

[0066] More specifically, the acting surface 221 of the inner wall of the movable valve sleeve 22 is arranged in a wave shape and forms at least two parking positions (i.e. inner recesses 221A and 221B); wherein the movable valve sleeve 22 moves axially, and the radial abutting member 241 falls into the parking position of the acting surface 221, so as to open or seal the channel 21A, so as to drive the sealing assembly 3 to open or seal the water outlet part 15.

[0067] More specifically, in order to improve the sealing and friction resistance, a V-shaped sealing member 6 is arranged on the outer circumferential ring groove of the movable valve sleeve 22 and acts on the inside of the pressure chamber 16 to enable the movable valve sleeve 22 to move axially in the pressure chamber 16 in a sealed manner, thus ensuring that the movable valve sleeve 22 moves smoothly in the pressure chamber 16 and does not fail due to water leakage.

[0068] Furthermore, the several drain channels 18 include a first drain channel 18A, a second drain channel 18B and a third drain channel 18C.

[0069] The first drain channel 18A is used to drain the water flow in the auxiliary chamber 17; when the switch group is opened, the water in the auxiliary chamber 17 and the second pressure stabilizing chamber 42 is drained to open the water inlet part 14 and the pressure chamber 16.

[0070] The second drain channel 18B is connected to the channel 21A and is used to drain the water flow in the first pressure stabilizing chamber 31; after the channel 21A is opened, the water flow in the first pressure stabilizing chamber 31 is drained from the shell 11, thereby changing the pressure of the sealing lip 32 to smoothly open the water outlet part 15.

[0072] In actual assembly and use,

[0073] As shown in Figure 1 Fig. 8, the present embodiment illustrates a toilet flushing assembly provided with a flushing water supply valve, which includes the following parts: at least two triangular valves (not shown in the figure), a water pump 9, a waterway switching valve 8, a connecting pipe 91, a shell 11, a base 12, a top cover 13, a water inlet part 14, a water outlet part 15, a pressure chamber 16, an auxiliary chamber 17, several drain channels 18, an adjusting seat 21, a movable valve sleeve 22, a first elastic member 23, an elastic switching structure 24, a pressing member 241, a movable frame 242, a second elastic member 243, a sealing lip 32, a sealing assembly 3, a switch assembly 4, a sealing diaphragm 41, a second pressure stabilizing chamber 42, a driving group 43, a V-shaped sealing member 6, a one-way valve 7 and an air pressure switch (not shown in the figure).

[0074] In assembly:

[0075] (1) the injection molding adjusting seat 21 is buckled on the movable frame 242, so that the movable frame 242 can swing relative to the adjusting seat 21; then the pressing piece 241 is arranged on one side of the movable frame 242, and it is to be explained that the pressing piece 241 is movable, so that the movable frame 242 can still be kept in the top-holding state during the lever swing process, of course, the pressing piece 241 can also be integrally formed with the movable frame 242, and the same effect can also be achieved, but the reliability and accuracy are higher when the pressing piece 241 is arranged to be movable;

[0076] Then a blocking plug is arranged at the other end of the movable frame 242 on the same side, and is arranged opposite to the channel 21A; finally, the second elastic member 243 (i.e. spring) is arranged to abut against the adjusting seat 21 and the pressing piece 241 at both ends;

[0077] (2) after the V-shaped sealing member 6 is arranged on the outer periphery of the movable valve sleeve 22, the first elastic member 23 (spring) is arranged on the movable valve sleeve 22, and it is to be explained that the elastic force of the first elastic member 23 is set at the factory, so as to ensure the speed of the subsequent first elastic member 23 pushing the movable valve sleeve to move;

[0078] (3) the movable valve sleeve 22 is sealed and arranged in the opening of the pressure cavity 16 together with the adjusting seat 21;

[0079] (4) the sealing lip 32 is arranged on the water inlet position of the water outlet 15 on the base 12, and the lip edge of the sealing lip 32 abuts against between the adjusting seat 21 and the base 12; at this time, the sealing lip 32 separates the water inlet 14, the water outlet 15 and the first pressure maintaining cavity 31 to form, and the water flows into the first pressure maintaining cavity 31 from the drainage hole 32A of the sealing lip 32; after assembly, the shell 11 and the base 12 are fixed;

[0080] (5) the sealing diaphragm 41 and the connecting rod 431 connected with the deformation member 433 are also arranged on the upper position (i.e. top position) of the shell 11, one end of the connecting rod 431 is located in the second pressure maintaining cavity 42 close to one end of the sealing diaphragm 41, the other end is sleeved with the third elastic member 432 (spring) and connected with the deformation member 433, and it is to be explained that after the top cover 13 is arranged, a certain gap is formed between the top cover 13 and the deformation member 433, like an air cavity, only by injecting gas with pressure, the deformation member 433 can be deformed, thereby driving the connecting rod 431 to open the water passing hole B downward, and the third elastic member 432 drives the reset, and the deformation member 433 and the third elastic member 432 realize fast reset;

[0081] (6) after the top cover 13 and the shell 11 are fixed, the air pressure valve (prior art) is fixed on the closestool, and is connected with the top cover 13 through a gas pipe, and the air pressure generated after pressing can drive the deformation member 433 to act;

[0082] (7) The entire flushing water supply control valve is now assembled. Then, the municipal water inlet pipe (not shown in the figure), the flushing water supply control valve and the water tank replenishment valve are connected by a three-way valve. The water from the municipal water inlet pipe enters the water tank replenishment valve for replenishment and storage, and at the same time enters the water inlet 14. However, the flushing water supply control valve is not open at this time, and the water flow can only replenish water.

[0083] (8) Similarly, a three-way valve and a connecting pipe 91 are used to connect the water pump 9, the flushing water supply control valve and the water circuit switching valve 8. A one-way valve 7 is installed in the connecting pipe 91 to limit the water flow from affecting each other when the water pump 9 and the flushing water supply control valve work alone.

[0084] (9) The water circuit switching valve 8 is connected to the brush ring water channel 51 and the main flush water channel 52 of the toilet (toilet) to complete the assembly of the entire flushing assembly.

[0085] When using:

[0086] (1) As Figure 8 As shown, when the power is on, the water pump 9 draws water from the water tank and enters the water circuit switching valve 8. It first supplies water to the brush ring water channel 51. After rinsing for a certain period of time, the water pump 9 is turned off. The water circuit switching valve 8 loses the water pressure impact, falls back and switches to the main flushing water channel 52. The water pump 9 is turned on again. At this time, the water flow enters the main flushing water channel 52 for rinsing. After rinsing for a certain period of time, it is turned off and reset to the original state.

[0087] (2) In the event of a power outage (loss of power), the water pump 9 will not function properly, such as... Figure 5 As shown, the consumer only needs to press the air pressure valve once (existing technology). At this time, a pressurized gas is introduced into the air pressure chamber through the air pipe, pushing the deformable part 433 to move downward and overcoming the spring force of the third elastic part 432. After the linkage rod 431 moves down, the water passage hole B is opened. At this time, the water in the second pressure stabilizing chamber 42 is discharged from the water passage hole B and the second drain channel 18B. The pressure on the sealing diaphragm 41 side is small, while the water pressure in the water inlet 14 is large. The quick-top sealing diaphragm 41 is pushed so that the water flows into the pressure chamber 16 quickly and pushes the movable valve sleeve 22 to the bottom quickly. This process takes a very short time, and the movable valve sleeve 22 is pushed to the bottom of the pressure chamber instantly.

[0088] When the consumer presses the button once and releases it, the device quickly resets under the support of the deformable element 433 and the third elastic element 432, thereby sealing the water passage B. At this time, the second pressure stabilizing chamber 42 is full of water, and the sealing diaphragm 41 seals the pressure chamber 16. The pressure chamber 16 is now filled with water. Figure 6 As shown;

[0089] (3) Figure 7As shown, the third drain passage 18C is provided on the top side of the pressure chamber 16, and has a small water passing area. Under the action of the first elastic member 23, the water flow is slowly discharged, and the movable valve sleeve 22 is upwardly moved. During the upward movement, the wavy action surface 221 inside the movable valve sleeve 22 cooperates with the abutting member 241, and when falling into the inner recess 221A (i.e. the parking position), the passage 21A is opened (of course, the reverse arrangement can also be provided, i.e. when falling into the inner recess 221A, the passage 21A is closed, and both arrangements fall within the protection scope). The water flow in the first pressure stabilizing chamber 31 flows into the passage 21A, and then flows out from the first drain passage 18A. After the pressure in the first pressure stabilizing chamber 31 is released, the water flow in the water inlet portion 14 pushes open the sealing lip 32, and then flows into the water path switching valve 8 from the water outlet portion 15, and then flows into the brush circle water channel 51 for flushing;

[0090] (4) With the continuous and slow upward movement of the movable valve sleeve 22, the movable frame 242 is swung back to block the passage 21A. After the water inlet portion 14 fills the first pressure stabilizing chamber 31 with water, the water pressure on both sides of the sealing lip 32 is the same, and the water outlet portion 15 is again covered. At this time, the water path switching valve 8 falls back after losing the water flow impact, and during the falling back, it is switched to the main flushing water channel 52 to be opened, and the brush circle water channel 51 is closed;

[0091] (5) The movable valve sleeve 22 continues to slowly move upwardly, and falls into another inner recess 221B (another parking position). The movable frame 242 is swung again to open the passage 21A, and the sealing lip 32 is also opened to supply water to the water path switching valve 8, and then flushes water from the main flushing water channel 52. Until the movable valve sleeve 22 moves upwardly, and the abutting member 241 moves out of the inner recess 221B, the water outlet is closed.

[0092] During the process, the water flow directly enters from the municipal pipeline, but only for water supply, and the water pressure change will not affect the movement of the entire movable valve sleeve 22. The entire process is stable and constant. By setting the elastic force value of the first elastic member 23, the water passing area of the third drain passage 18C, and the distance between the inner recesses 221A and 221B (i.e. the parking position), sequential and constant intermittent water supply is realized.

[0093] The utility model provides a kind of for flushing water supply control valve under no electricity state and toilet flushing assembly, it is simple in structure, easy to make, easy to realize and low in cost;The flushing water supply control valve of the utility model breaks the malady that traditional mechanical type and electric control type valve body cannot be shared, still can realize flushing function under no electricity state;Here flushing function is not simple switch flushing function, but flushing function and effect with the following multiple effects fusion, as follows:First, one-key opening (one-time pressing) can open sequential flushing, that is, only need to press once to realize sequential flushing of circle flushing channel and main flushing channel, without multiple pressing, experience is good;Second, on the basis of one-key pressing, flushing time (i. e. control flushing volume) can be well controlled, after switch assembly opens, water flow impacts movable valve sleeve in pressure chamber to chamber bottom, and then quickly closes the communication of inlet portion and pressure chamber, at this time, water flow in pressure chamber flows out from drain channel, and slowly extrudes chamber water flow under the action of first elastic member, movable valve sleeve slowly rises in this process, its upper acting surface cooperates with elastic switching structure, opens channel, and then linkage sealing assembly opens, water flow flows out from water outlet portion, and then realizes circle flushing channel flushing;With the rising of movable valve sleeve, elastic switching structure is closed under the position change of acting surface, at this time, waterway switching valve position switches, and switches to main flushing channel water outlet;And with the continuous rising of movable valve sleeve, elastic switching structure opens the channel again, and then opens water outlet portion water outlet, and then realizes main flushing channel water supply;A very important improvement point here is that flushing time and flushing volume of entire circle flushing channel and main flushing channel are set according to the position change of movable valve sleeve, and the speed of movable valve sleeve position change is dominated by the elasticity of first elastic member, the elasticity of first elastic member is relatively constant and stable, and the control of entire flushing time is very uniform, without the difference of flushing time and flushing volume of circle flushing channel and main flushing channel each time, which cannot be realized in existing structure, because existing structure is based on water pressure, and such water pressure is in constant fluctuation state, flushing time is long when water pressure is large, and flushing time is short when water pressure is small, which cannot be quantified, cannot guarantee constant time, and user experience is very poor, intermittent opening and closing of the mode of the utility model is not related to inlet water pressure, and is constant control, flushing time (water volume) is set nearly uniform each time;Furthermore, the volume of entire structure is small, and it does not need to use inlet bucket component to operate;In summary, flushing control valve of the utility model realizes small volume, one-key control and one-time pressing, can realize sequential circle flushing channel and main flushing channel flushing, and constant control flushing time and water volume each time, can still be used smoothly under power failure state, and experience is good, the whole product design idea and structure are very ingenious.

[0094] The above description of specification and examples is used to explain the protection scope of the utility model, and does not constitute the limitation to the protection scope of the utility model.
