Description

Technical Field

[0001] The invention relates to the technical field of bathrooms, and in particular to a flushing system and an intelligent toilet. Background Art

[0002] With the continuous improvement of people's living standards, various forms of functional toilets, commonly known as toilets, have emerged, and smart toilets have been extended from this to bring users a better user experience. Existing smart toilets usually have a flushing system that can spray water columns on the user's parts to be cleaned to achieve flushing. The flushing system usually includes multiple electrical components and pipes that allow water to flow. In actual use, the start and stop of electrical components will cause changes in the water pressure in the pipeline, thereby generating pressure fluctuations. The pressure changes will cause the pipeline to vibrate, which will cause noise to affect the user experience at the least, and damage the flushing system at the worst, affecting the normal operation of the smart toilet. In addition, during the user's use, the existing flushing system will retain the accumulated water that was not discharged in time during the previous use. The accumulated water is easy to breed bacteria and is unhygienic. Summary of the invention

[0009] A shell, wherein a water inlet and a water outlet are provided at the bottom of the shell, wherein the water inlet and the water outlet are respectively communicated with the water pipe, and a vent is provided at the top of the shell, wherein a receiving cavity is provided inside the shell, and wherein the vent enables the receiving cavity to communicate with the outside;

[0010] A float, wherein the float is arranged in the accommodating cavity and a gap exists between the outer wall of the float and the inner wall of the shell so that the float can float up and down in the accommodating cavity; a sealing plug is provided at the top of the float, and an opening is provided at the bottom of the float, and water flows into the accommodating cavity and the float through the water inlet, and a first air cavity is formed between the liquid surface of the accommodating cavity and the inner wall of the float, and the float floats up to the sealing plug to seal the vent, thereby forming a second air cavity between the liquid surface and the inner wall of the shell, and the air pressure of the first air cavity and the second air cavity changes with the rise and fall of the liquid surface.

[0011] A spray gun assembly is arranged at the water outlet end of the water pipeline.

[0012] In an exemplary embodiment, the float includes a main body and a transition portion connected to the main body, and the sealing plug is arranged on a side of the transition portion away from the main body, and the cross-sectional area of ​​the transition portion gradually decreases from the side wall of the main body toward the outer periphery of the sealing plug.

[0013] In an exemplary embodiment, the outer contour of the main body is substantially cylindrical, and the side wall of the main body is provided with a plurality of grooves, and the grooves are used for ventilation and air replenishment.

[0014] In an exemplary embodiment, the water inlet is arranged on the side wall of the shell, and the water outlet is arranged opposite to the vent.

[0015] In an exemplary embodiment, the water inlet is arranged opposite to the vent, and the water outlet is arranged on the side wall of the shell.

[0016] In an exemplary embodiment, the housing comprises a main housing and a cover, the main housing is detachably connected to the cover, and the main housing and the cover together form the accommodating cavity;

[0017] The shock absorbing assembly further comprises a sealing ring, and the sealing ring is sandwiched between the main shell and the cover body.

[0018] In an exemplary embodiment, a plurality of ribs are protruded from the inner wall of the main shell at intervals along the circumference thereof, and the ribs are used to support the buoy.

[0019] In an exemplary embodiment, a protrusion is provided at the vent, and a radial dimension of the protrusion is smaller than a radial dimension of the sealing plug. When the sealing plug floats up with the buoy, the sealing plug first abuts against the protrusion.

[0020] A smart toilet comprises a toilet body and the flushing system as described above, wherein the flushing system is arranged on the toilet body, and the water pipeline is communicated with the pipeline of the toilet body.

[0021] In an exemplary embodiment, the flushing system also includes a heater and a pulse valve, and the heater and the pulse valve are arranged on the water pipeline, and the shock absorbing assembly is arranged between the heater and the pulse valve, and the water flows through the heater, the shock absorbing assembly, the pulse valve, and the spray gun assembly in sequence and then is sprayed out.

The flushing system includes a water pipeline, a shock absorbing assembly and a spray gun assembly. The shock absorbing assembly includes a shell and a float. By setting the structure of the shell and the float, when the water flows into the accommodating chamber through the water inlet of the shell, it also flows into the inside of the float, and the liquid surface and the inner wall of the float form a first air cavity. The water flows into the accommodating chamber and also makes the float float, so that the sealing plug at the top of the float seals the vent and forms a second air cavity between the liquid surface and the inner wall of the shell. The air pressure of the first air cavity and the second air cavity changes with the rise and fall of the liquid surface. When the water pressure of the water flow increases, the liquid surface inside the shock absorbing assembly rises, the first air cavity and the second air cavity absorb the pressure energy and the air pressure increases, and the air pressure in the first air cavity and the second air cavity can absorb the increased water pressure; when the water pressure of the water flow decreases, the liquid surface inside the shock absorbing assembly decreases, the first air cavity and the second air cavity release the absorbed pressure energy and the air pressure decreases, and the air pressure in the first air cavity and the second air cavity can compensate for the reduced water pressure. The setting of the shock-absorbing component effectively suppresses the pressure fluctuation in the water pipeline and reduces the vibration of the water pipeline.

[0024] When the water pipe stops taking in water, the buoy will drop, allowing the inside of the shock-absorbing component to communicate with the outside world, achieving air pressure balance inside and outside the water pipe, allowing all the water in the water pipe to flow out, and effectively preventing water from remaining in the water pipe.

DETAILED DESCRIPTION

[0031] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] This embodiment provides a flushing system 100 and a smart toilet with the flushing system 100, wherein when the flushing system 100 is in operation, the water flow and water pressure are stable, and it can ensure that there is no water residue in the flushing system 100 after the user uses it, and ensure the internal hygiene of the flushing system 100, so as to bring a good user experience. The specific scheme is described through the following embodiments.

[0035] It should be noted that smart toilets are usually connected to tap water pipes or grey water pipes to provide water for the smart toilets.

[0036] The smart toilet of this embodiment includes a toilet body and a flushing system 100. The flushing system 100 is arranged on the toilet body. The flushing system 100 can provide the user with cleaning functions such as toilet washing and toilet washing.

[0037] The flushing system 100 includes a water conduit 10. The interior of the water conduit 10 is used to circulate water. The water flow inside the flushing system 100 usually has a certain pressure. The water conduit 10 is connected to the pipeline of the toilet body so that water flows from the pipeline of the toilet body into the water conduit 10.

[0038] See also Figure 1 The flushing system 100 includes a heater 20, a pulse valve 30 and a spray gun assembly 40. The heater 20, the pulse valve 30 and the spray gun assembly 40 are all arranged on the waterway pipeline 10 and communicated with the waterway pipeline 10.

[0039] Furthermore, the two ends of the water pipe 10 are respectively a water inlet end 11 and a water outlet end 12. The heater 20 is arranged at one end of the water pipe 10 close to the water inlet end 11, and the spray gun assembly 40 is arranged at the water outlet end 12 of the water pipe 10. The pulse valve 30 is arranged between the heater 20 and the spray gun assembly 40.

[0040] Among them, the pulse valve 30 can provide a gradual sense of pressure and impact. The heater 20 can heat the water to a comfortable temperature for the human body. After being heated by the heater 20, the water flows to the pulse valve 30 and the spray gun assembly 40. The spray gun assembly 40 can use the heated water to wash the user's part to be washed. It can be understood that the setting of the heater 20 and the pulse valve 30 can provide the user with a more comfortable washing experience.

[0041] Continue to see Figure 1 The flushing system 100 further includes a shock absorbing assembly 50. The shock absorbing assembly 50 is disposed on the waterway pipe 10 and is in communication with the waterway pipe 10.

[0042] In some embodiments, the shock absorbing assembly 50 is disposed between the heater 20 and the pulse valve 30 , and the water flows through the heater 20 , the shock absorbing assembly 50 , and the pulse valve 30 in sequence, and then is sprayed out through the spray gun assembly 40 .

[0043] In the direction from the water inlet end 11 of the water pipe 10 toward the water outlet end 12, the heights of the shock absorbing device, the pulse valve 30 and the spray gun assembly 40 are successively lowered to form a liquid level difference between the water inlet end 11 and the water outlet end 12 of the water pipe 10, so that the water flow can flow out of the water pipe 10 under the action of its gravity, so as to facilitate the emptying of the water flow in the water pipe 10.

[0044] The opening and closing of the heater 20, the pulse valve 30 or the spray gun assembly 40 may cause the water pressure in the water pipe 10 to change and generate pressure fluctuations. The setting of the shock absorbing assembly 50 can effectively suppress the pressure fluctuations, ensure the stability of the water pressure and the flow rate, and have a good shock absorbing effect.

[0045] Specifically, see Figures 2 to 4 The shock absorbing assembly 50 includes a housing 51. An accommodating chamber 511 is provided inside the housing 51.

[0046] In some embodiments, the housing 51 includes a main housing 512 and a cover 513. The main housing 512 and the cover 513 are detachably connected, and the main housing 512 and the cover 513 enclose a receiving chamber 511.

[0047] Specifically in this embodiment, please refer to Figure 3 and Figure 4 , a first receiving groove 5121 is provided at the top of the main housing 512. The notch direction of the first receiving groove 5121 faces the cover body 513. The cover body 513 includes a main cover body 5131 and a sealing portion 5132, the sealing portion 5132 is arranged along the periphery of the main cover body 5131, and is convexly arranged on one side of the main cover body 5131 facing the main housing 512. When the cover body 513 is covered on the main housing 512, the surface of the main cover body 5131 abuts against the top end surface of the main housing 512, the sealing portion 5132 is accommodated in the first receiving groove 5121, and the outer peripheral wall of the sealing portion 5132 is close to or directly attached to the side wall of the main housing 512 to seal the notch of the main housing 512. The arrangement of the outer peripheral wall of the sealing portion 5132 close to or directly attached to the side wall of the main housing 512 can effectively prevent the cover body 513 from shaking in the direction perpendicular to the axis of the main housing 512.

[0048] For ease of description, the two opposite sides of the main cover 5131 are defined as a first side 5131a and a second side 5131b, wherein the first side 5131a is the side of the main cover 5131 facing the main housing 512, and the second side 5131b is the side of the main cover 5131 facing away from the main housing 512.

[0049] The sealing portion 5132 and the main cover 5131 are enclosed to form a second receiving groove 5133. The notch direction of the second receiving groove 5133 faces the direction of the main housing 512. The inner peripheral wall of the sealing portion 5132 forms the side wall of the second receiving groove 5133, and the first surface 5131a of the main cover 5131 forms the bottom wall of the second receiving groove 5133. It can be understood that the receiving cavity 511 is composed of the first receiving groove 5121 and the second receiving groove 5133.

[0050] In some embodiments of the present application, the top of the main housing 512 is recessed along its periphery to form a step portion 5122. The cover 513 is provided with a flange 5134 adapted to the step portion 5122, and the flange 5134 is convexly arranged on the outer peripheral wall of the sealing portion 5132. The arrangement of the step portion 5122 and the flange 5134 forms a good sealing structure, which can improve the sealing performance of the housing 51.

[0051] In some embodiments, the shock absorbing assembly 50 further includes a sealing ring 52 , which is sandwiched between the main shell 512 and the cover 513 to further improve the sealing performance of the shell 51 .

[0052] Specifically in this embodiment, the sealing ring 52 is disposed on the outer peripheral wall of the sealing portion 5132. When the cover 513 is connected to the main housing 512, the sealing ring 52 is clamped between the step portion 5122 and the flange 5134.

[0053] A plurality of protrusions 5123 are provided on the peripheral wall of the top of the main housing 512. The plurality of protrusions 5123 are arranged at intervals along the periphery of the main housing 512. A plurality of engaging portions 5135 are arranged at intervals along the periphery of the cover 513. Each engaging portion 5135 is correspondingly connected to each protrusion 5123 so as to mount the cover 513 on the main housing 512. Further, a slot is provided on the engaging portion 5135, and the protrusion 5123 can be accommodated in the slot.

[0054] See Figure 2 and Figure 3 In some embodiments, at least one of the protrusions 5123 is provided with limiting portions 5124 on both sides. The engaging portion 512 is located between the two limiting portions 5124. The setting of the limiting portions 5124 can limit the rotation of the cover 513, further fix the cover 513, and ensure the stability of the cover 513.

[0055] It can be understood that in this embodiment, the detachable connection between the main housing 512 and the cover 513 is a snap connection. In other embodiments, the main housing 512 and the cover 513 can also be connected by threaded connection, screw connection, etc., which can be set according to actual needs, as long as the accommodating cavity 511 can be formed inside the housing 51 and the sealing of the housing 51 is guaranteed, and there is no limitation here.

[0056] The top of the housing 51 is provided with a vent 514. Specifically, the vent 514 can be provided at the center of the cover 513. The provision of the vent 514 enables the accommodating cavity 511 to communicate with the outside.

[0057] The bottom of the housing 51 is provided with a water inlet 515 and a water outlet 516. The water inlet 515 and the water outlet 516 are connected to the accommodating chamber 511 and the water channel 10 respectively, so that the water in the water channel 10 can flow into the accommodating chamber 511 through the water inlet 515 and flow out of the water channel 10 from the water outlet 516.

[0058] In this embodiment, the water inlet 515 is disposed on the side wall of the main housing 512. The water outlet 516 is disposed at the bottom end of the main housing 512, and is disposed opposite to the vent 514. In other embodiments, the water inlet 515 and the vent 514 may be disposed opposite to each other. The specific arrangement may be based on actual needs, and is not limited here. As long as water can flow from the water inlet 515 into the accommodating chamber 511 and flow out from the water outlet 516, it will be sufficient.

[0059] See also Figure 4 The shock absorbing assembly 50 includes a float 53. The float 53 is disposed in the accommodating chamber 511 of the housing 51. An opening 531 is disposed at one end of the float 53 away from the vent 514, so that the interior of the float 53 is connected to the interior of the accommodating chamber 511. When pressurized water flows from the water inlet 515 into the accommodating chamber 511, the water also flows into the interior of the float 53, and a first air cavity is formed between the liquid surface and the inner wall of the float 53.

[0060] The air pressure of the first air chamber can change with the rise and fall of the liquid level, effectively alleviating the pressure fluctuation caused by the change of water pressure caused by the start and stop of the heater 20, the pulse valve 30 or the spray gun assembly 40, and reducing the vibration of the flushing system 100 caused by the pressure fluctuation.

[0061] Specifically, when the water pressure of the water flow increases, the liquid level of the accommodating chamber 511 rises, and the first air cavity absorbs and stores the increased water pressure energy to avoid an increase in the water pressure in the water pipe 10; when the water pressure of the water flow decreases, the liquid level of the accommodating chamber 511 drops, and the first air cavity releases the absorbed pressure energy to avoid a decrease in the water pressure in the water pipe 10, thereby maintaining a stable water pressure in the water pipe 10.

[0062] There is a gap between the outer wall of the float 53 and the inner wall of the shell 51, so that the float 53 can float up and down in the accommodating chamber 511. The float 53 floats to its top to cover and seal the vent 514, so that a second air cavity is formed between the liquid surface of the accommodating chamber 511 and the inner wall of the shell 51.

[0063] The air pressure of the second air cavity can also change with the rise and fall of the liquid level. Specifically, when the water pressure of the water flow increases, the liquid level of the accommodating chamber 511 rises, and the second air cavity absorbs and stores the increased water pressure energy to prevent the water pressure in the waterway pipe 10 from increasing; when the water pressure of the water flow decreases, the liquid level of the accommodating chamber 511 decreases, and the second air cavity releases the absorbed pressure energy to prevent the water pressure in the waterway pipe 10 from decreasing, thereby maintaining the water pressure in the waterway pipe 10 stable.

[0064] It should be noted that the shock absorbing assembly 50 is equivalent to being connected in series to the water pipe, and the pressure fluctuations in the water pipe 10 before and after the shock absorbing assembly 50 will cause the liquid level in the accommodating chamber 511 in the shock absorbing assembly 50 to rise and fall. And because there is a gap between the outer wall of the float 53 and the inner wall of the shell 51, and the interior of the float 53 is connected to the accommodating chamber 511, it can be understood that the liquid level in the float 53 is consistent with the liquid level between the outer wall of the float 53 and the inner wall of the shell 51, and rises and falls synchronously. The first air cavity and the second air cavity are independent of each other and can change synchronously with the rise and fall of the liquid level. The first air cavity and the second air cavity have the effect of cutting peaks and filling valleys. The two work together to adjust the water pressure in the water pipe 10 at the same time to suppress pressure fluctuations and achieve the purpose of reducing the vibration of the entire flushing system 100 when it is working.

[0065] In some embodiments of the present application, the shock absorbing assembly 50 includes a sealing plug 54. The sealing plug 54 is disposed on the top of the buoy 53, and the sealing plug 54 can seal the vent 514. Specifically, the sealing plug 54 covers and seals the vent 514 as the buoy 53 floats upward.

[0066] Further, the cover body includes a protrusion 5136, which is arranged at the vent. The protrusion 5136 cooperates with the sealing plug 54 to better seal the vent 514. Specifically, the protrusion 5136 is arranged on the first surface of the main cover body, and the protrusion 5136 is connected to the vent 514. The radial dimension of the protrusion 5136 is smaller than the radial dimension of the sealing plug 54. Compared with the surface of the first surface 5131a of the main cover body 5131, the end face of the protrusion 5136 is closer to the sealing plug 54. Therefore, when the sealing plug 54 floats up with the float 53, it first abuts against the protrusion 5136 and generates a pressing force on the protrusion 5136. When the sealing plug 54 is a flexible plug, the sealing plug 54 abuts against the protrusion 5136 and can be deformed to tightly cover the protrusion 5136, thereby ensuring the sealing of the vent 514.

[0067] In some embodiments, the outer peripheral surface of the protrusion 5136 is an inclined surface, and the inclined surface is inclined from the center of the vent 514 toward the circumference of the main cover body 5131.

[0068] It should be noted that the connection between the sealing plug 54 and the buoy 53 can be interference fit, threaded connection, bonding, etc., which can be set according to actual needs and is not limited here. The sealing plug 54 can be a rubber plug, a silicone plug, etc.

[0069] The buoy 53 includes a main body 532 and a transition part 533. The transition part 533 is connected to the main body 532. The transition part 533 and the main body 532 can be integrally formed. The sealing plug 54 is arranged on one end of the transition part 533 away from the main body 532.

[0070] The cross-sectional area of ​​the transition portion 533 gradually decreases from the side wall of the main body 532 toward the outer periphery of the sealing plug 54 to increase the volume of the second air cavity, thereby increasing the adjustable range of the water pressure.

[0071] The outer contour of the main body 532 is roughly cylindrical. In the direction perpendicular to the axis of the shell, the aperture of the main body 532 is substantially the same as the aperture of the main shell 512, so that the shell 51 has a guiding effect on the up and down movement of the float 53, so that the float 53 can rise smoothly, and avoid the sealing plug 54 shaking when floating with the float 53, so as to prevent the vent 514 from being unable to be sealed.

[0072] See Figure 5 Combined with Figure 4 In some embodiments, the side wall of the main body 532 is provided with a plurality of grooves 5321, and the grooves 5321 are recessed toward the inside of the main body 532. Specifically in this embodiment, there are six grooves 5321, and the inner wall of the groove 5321 is arc-shaped, so that the cross section of the main body 532 in this embodiment is an arc-shaped hexagon. In other embodiments, the number of grooves 321 can also be three, four, etc., which can be set according to actual needs and is not limited here.

[0073] The groove 321 is used for ventilation and air replenishment. Specifically, the provision of the groove 321 is conducive to the flow of external gas inside the housing 510 when the main housing 512 is connected to the outside after the liquid pipeline stops inflowing liquid, and is convenient for automatically replenishing the air inside the float 53, ensuring that the first air cavity can be stably formed in the float 530 in subsequent use, so that the shock absorbing device 50 of this embodiment can be used stably for a long time.

[0074] A plurality of convex ribs 5125 are provided on the inner wall of the main housing 512. The convex ribs 5125 are used to support the buoy 53 to prevent the buoy 53 from blocking the water inlet 515. Specifically, the plurality of convex ribs 5125 are arranged at intervals along the circumference of the main housing 512. When no water flows into the accommodating chamber 511, the buoy 53 falls under the action of its gravity, and the end surface of the buoy 53 having the opening 531 contacts the surface of the convex rib 5125.

[0075] Furthermore, in a cross section perpendicular to the axial direction of the main body 32, the maximum distance between the groove 5321 and the inner wall of the main shell 512 is less than the radial length of the rib 5125, so as to ensure that even if the float 53 rotates under the action of water, the rib 5125 can support it when the float 53 falls.

[0076] When the water pipe 10 stops taking in water, the buoy 53 descends to connect the inside of the shock absorbing assembly 50 with the outside, thereby achieving air pressure balance inside and outside the water pipe 10, facilitating the rapid flow of water in the water pipe 10 and facilitating the outflow of all water in the water pipe 10, effectively preventing water from remaining in the water pipe 10.

[0077] The ability to drain the water in the water pipe 10 means that the flushing system 100 can stably provide a constant temperature water flow, effectively preventing the remaining cooled water in the flushing system 100 from flowing out the next time the user uses the flushing system 100 of the smart toilet, resulting in a poor user experience.

[0078] It can be seen from the above technical solution that the flushing system 100 and the smart toilet provided in this embodiment have the following advantages and beneficial implementation effects.

[0079] By setting the structure of the shock-absorbing component 50 in the flushing system 100, the water pressure in the water pipe 10 can be adjusted, and the pressure fluctuation caused by the start and stop of the heater 20, the pulse valve 30, etc. can be effectively reduced, and the water pressure and flow rate of the water flow can be kept stable, and a good shock-absorbing effect can be achieved. In addition, when the flushing system 100 stops taking in water, the shock-absorbing component 50 can be connected to the outside atmosphere to quickly drain the accumulated water in the water pipe 10.

[0080] The above embodiments are merely exemplary descriptions of the structures. The structures in the embodiments are not fixed combination structures. In the absence of structural conflicts, the structures in multiple embodiments can be used in any combination.

[0081] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
