Abstract

The present invention provides a flushing system and an intelligent toilet. The flushing system includes a water pipe, a shock-absorbing assembly, and a spray gun assembly. The shock-absorbing assembly includes a shell and a float. By arranging the structures of the shell and the float, when water flows into the accommodating chamber through the water inlet of the shell, a first air cavity is formed between the liquid surface and the inner wall of the float. The flow of water into the accommodating chamber also causes the float to float up, so that the sealing plug on the top of the float seals the air vent and a second air cavity is formed 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 level. The first air cavity and the second air cavity jointly regulate the water pressure change in the water pipe, which can effectively suppress pressure fluctuations and make the shock-absorbing assembly have a good shock-absorbing effect. In addition, the descent of the float will make the inside of the shock-absorbing assembly communicate with the outside world, achieve air pressure balance inside and outside the water pipe, and effectively prevent water from remaining in the water pipe.

Description

Technical Field

[0001] The present invention relates to the technical field of bathroom fixtures, 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 provide users with a better user experience. Existing smart toilets usually have a flushing system that can spray water jets on the user's body parts to be cleaned to achieve flushing. The flushing system usually includes multiple electrical components and pipes that allow water to flow. During actual use, the start and stop of the electrical components will cause changes in the water pressure in the pipes, resulting in pressure fluctuations. The pressure changes will cause the pipes to vibrate, which at the very least will produce noise that affects the user experience, and at worst will damage the flushing system and affect the normal operation of the smart toilet. In addition, during use, the existing flushing system will retain accumulated water that was not discharged in time from the previous use. The accumulated water is prone to breeding bacteria and is unhygienic. Summary of the Invention

[0007] A water pipe, the interior of which is used for circulating water, with two ends of the water pipe being a water inlet end and a water outlet end respectively;

[0008] A shock absorbing assembly is provided on the water inlet end of the water pipe and is in communication with the water pipe; the shock absorbing assembly comprises:

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

[0010] a float, the float being disposed in the accommodating chamber and having a gap 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 chamber; a sealing plug being provided on the top of the float and an opening being provided on the bottom of the float, water flowing into the accommodating chamber and the float through the water inlet, forming a first air cavity between the liquid surface of the accommodating chamber and the inner wall of the float, the float floating 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, the air pressure of the first air cavity and the second air cavity varying with the rise and fall of the liquid surface;

[0011] A spray gun assembly, the spray gun assembly being arranged at the water outlet end of the water pipe;

[0012] The buoy includes a main body and a transition portion connected to the main body, the sealing plug is provided 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] The outer contour of the main body is roughly 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 provided on a side wall of the housing, 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 includes a main housing and a cover, wherein 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 includes a sealing ring, which is sandwiched between the main shell and the cover.

[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 described above, wherein the flushing system is arranged on the toilet body, and the water pipe 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, which are arranged on the water pipeline, and the shock absorbing assembly is arranged between the heater and the pulse valve. The water flows through the heater, the shock absorbing assembly, the pulse valve, and the spray gun assembly in sequence and is then sprayed out.

[0022] It can be seen from the above technical solutions that the present invention has at least the following advantages and positive effects:

[0023] The present invention relates to a flushing system and a smart toilet equipped with the same. The flushing system includes a water pipeline, a shock-absorbing assembly, and a spray gun assembly. The shock-absorbing assembly includes a housing and a float. The housing and float are structurally configured so that when water flows through the water inlet of the housing and into the accommodating chamber, it also flows into the interior of the float, forming a first air cavity between the liquid surface and the inner wall of the float. The flow of water into the accommodating chamber also causes the float to rise, causing the sealing plug at the top of the float to seal the vent, thereby forming a second air cavity between the liquid surface and the inner wall of the housing. The air pressure in the first and second air cavities varies with the rise and fall of the liquid surface. When the water pressure increases, the liquid surface within the shock-absorbing assembly rises, and the first and second air cavities absorb pressure energy, increasing the air pressure. The air pressure in the first and second air cavities can absorb the increased water pressure. When the water pressure decreases, the liquid surface within the shock-absorbing assembly drops, and the first and second air cavities release the absorbed pressure energy, decreasing the air pressure. The air pressure in the first and second air cavities can compensate for the decreased 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, making the inside of the shock-absorbing component 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 embodying the features and advantages of the present invention are described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations herein are intended to be illustrative rather than limiting.

[0032] In the description of this application, it should be understood that in the embodiments shown in the accompanying drawings, indications of directions or positional relationships (such as up, down, left, right, front, and back) are provided solely for the purpose of facilitating the description of this application and simplifying the description. They are not intended to indicate or imply that the components or elements referred to must have, be constructed, or operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the descriptions of the positions of these elements change, these directional indications will also change accordingly.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0034] This embodiment provides a flushing system 100 and a smart toilet equipped with the flushing system 100. During operation, the flushing system 100 maintains stable water flow and pressure, ensuring that no water remains after use, ensuring internal hygiene within the flushing system 100 and providing a good user experience. The specific solution is described in 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 bidet washing.

[0037] Flushing system 100 includes a water conduit 10. Water flows through conduit 10. The water within flushing system 100 typically has a certain pressure. Conduit 10 communicates with the toilet's main piping, allowing water to flow from the toilet's main piping into 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 disposed on the waterway pipe 10 and communicated with the waterway pipe 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 provided at one end of the water pipe 10 near the water inlet end 11, and the spray gun assembly 40 is provided at the water outlet end 12 of the water pipe 10. The pulse valve 30 is provided between the heater 20 and the spray gun assembly 40.

[0040] The pulse valve 30 provides a gradual sense of pressure and impact. The heater 20 heats 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 then applies the heated water to the user's area to be rinsed. It can be understood that the configuration of the heater 20 and the pulse valve 30 provides a more comfortable rinsing experience for the user.

[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 is then 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 assembly, 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, pulse valve 30, or spray gun assembly 40 may cause changes in the water pressure in the water pipe 10, resulting in pressure fluctuations. The provision of the shock absorber assembly 50 can effectively suppress pressure fluctuations, ensuring stable water pressure and flow rate, and having a good shock absorption 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 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 opening of the first receiving groove 5121 faces the cover 513. The cover 513 includes a main cover 5131 and a sealing portion 5132. The sealing portion 5132 is provided along the periphery of the main cover 5131 and protrudes from the side of the main cover 5131 facing the main housing 512. When the cover 513 is placed on the main housing 512, the surface of the main cover 5131 abuts against the top end surface of the main housing 512. The sealing portion 5132 is accommodated in the first receiving groove 5121. The outer peripheral wall of the sealing portion 5132 is close to or directly in contact with the side wall of the main housing 512 to seal the opening of the main housing 512. The arrangement of the outer peripheral wall of the sealing portion 5132 close to or directly in contact with the side wall of the main housing 512 effectively prevents the cover 513 from shaking along the axis perpendicular to 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 together form a second receiving groove 5133. The notch of the second receiving groove 5133 faces toward the main housing 512. The inner peripheral wall of the sealing portion 5132 forms the sidewalls 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 chamber 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 stepped portion 5122. The cover 513 is provided with a flange 5134 that mates with the stepped portion 5122. The flange 5134 protrudes from the outer peripheral wall of the sealing portion 5132. The arrangement of the stepped 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] The outer peripheral wall of the top of the main housing 512 is provided with a plurality of protrusions 5123. The protrusions 5123 are spaced apart along the outer periphery of the main housing 512. The cover 513 is provided with a plurality of engaging portions 5135 spaced apart along its outer periphery. Each engaging portion 5135 is connected to a corresponding protrusion 5123 to mount the cover 513 on the main housing 512. Furthermore, the engaging portions 5135 are provided with slots into which the protrusions 5123 can be received.

[0054] See Figure 2 and Figure 3 In some embodiments, at least one protrusion 5123 is provided with a limit portion 5124 on both sides. The engaging portion 5135 is located between the two limit portions 5124. The provision of the limit portion 5124 can limit the rotation of the cover 513, further fix the cover 513, and ensure the stability of the cover 513.

[0055] It is understood that in this embodiment, the detachable connection between the main housing 512 and the cover 513 is a snap-fit ​​connection. In other embodiments, the main housing 512 and the cover 513 can also be connected by a threaded connection, a screw connection, etc. The specific configuration can be based on 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. 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 pipe 10 respectively, so that the water in the water pipe 10 can flow into the accommodating chamber 511 through the water inlet 515 and flow out of the water pipe 10 through the water outlet 516.

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

[0059] See also Figure 4 The shock-absorbing assembly 50 includes a float 53. The float 53 is disposed within the housing 511 of the housing 51. An opening 531 is defined at one end of the float 53, distal from the vent 514, connecting the interior of the float 53 with the interior of the housing 511. When pressurized water flows from the water inlet 515 into the housing 511, the water also flows into the float 53, forming a first air cavity 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, pulse valve 30 or spray gun assembly 40, and reducing the vibration of the flushing system 100 caused by pressure fluctuations.

[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. When the float 53 floats to its top, it can cover and seal the vent 514, thereby forming a second air cavity between the liquid level of the accommodating chamber 511 and the inner wall of the shell 51.

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

[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 is capable of sealing the vent 514. Specifically, the sealing plug 54 covers and seals the vent 514 as the buoy 53 floats upward.

[0066] Furthermore, the cover includes a protrusion 5136, which is located at the vent. The protrusion 5136 cooperates with the sealing plug 54 to better seal the vent 514. Specifically, the protrusion 5136 is located on the first surface of the main cover and is in communication with the vent 514. The radial dimension of the protrusion 5136 is smaller than that of the sealing plug 54. The end surface of the protrusion 5136 is closer to the sealing plug 54 than the surface of the first surface 5131a of the main cover 5131. As a result, when the sealing plug 54 rises with the buoy 53, it first abuts the protrusion 5136, exerting a compressive force on the protrusion 5136. If the sealing plug 54 is a flexible plug, the sealing plug 54 abuts the protrusion 5136 and can deform 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 5131.

[0068] It should be noted that the connection between the sealing plug 54 and the buoy 53 can be an interference fit, a threaded connection, an adhesive connection, 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 portion 533. The transition portion 533 is connected to the main body 532. The transition portion 533 and the main body 532 can be integrally formed. The sealing plug 54 is provided on one end of the transition portion 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 widening the adjustable range of the water pressure.

[0071] The main body 532 has a generally cylindrical outer profile. The aperture of the main body 532 is substantially the same as that of the main housing 512 in a direction perpendicular to the housing's axis. This allows the housing 51 to guide the vertical movement of the float 53, ensuring a smooth ascent of the float 53 and preventing the sealing plug 54 from swaying as it rises with the float 53, potentially preventing it from sealing the vent 514.

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

[0073] The groove 5321 is used for ventilation and air replenishment. Specifically, the provision of the groove 5321 facilitates the flow of external air within the housing 51 when the main housing 512 is connected to the outside world after the liquid pipeline stops inflowing liquid, thereby facilitating the automatic replenishment of air within the float 53, ensuring that the first air cavity can be stably formed within the float 53 during subsequent use, thereby ensuring that the shock absorbing assembly 50 of this embodiment can be used stably and for a long time.

[0074] The inner wall of the main housing 512 is provided with a plurality of ribs 5125. The ribs 5125 support the buoy 53 to prevent it from blocking the water inlet 515. Specifically, the ribs 5125 are spaced apart along the circumference of the main housing 512. When no water flows into the accommodating chamber 511, the buoy 53 descends under the action of its gravity, and the end surface of the buoy 53 with the opening 531 contacts the surface of the ribs 5125.

[0075] Furthermore, in a cross section perpendicular to the axial direction of the main body 532, 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 water stops flowing into the water pipe 10, the float 53 descends, allowing the interior of the shock-absorbing assembly 50 to communicate with the outside world, thereby achieving air pressure balance inside and outside the water pipe 10, facilitating rapid flow of water in the water pipe 10, and facilitating the complete outflow of water in the water pipe 10, effectively preventing water from remaining in the water pipe 10.

[0077] The ability to drain the water from 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 solutions that the flushing system 100 and the smart toilet provided in this embodiment have the following advantages and beneficial implementation effects.

[0079] The structural configuration of the shock-absorbing assembly 50 in the flushing system 100 regulates the water pressure within the water pipe 10, effectively mitigating pressure fluctuations caused by the activation and deactivation of the heater 20 and pulse valve 30, ensuring stable water pressure and flow rate, while providing excellent shock absorption. Furthermore, the shock-absorbing assembly 50 allows for communication with the outside atmosphere when the flushing system 100 stops receiving water, allowing for rapid drainage of accumulated water within 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] While the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are intended to be illustrative and exemplary rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. All changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
