Description

Technical Field

[0001] This utility model belongs to the field of toilet technology, specifically relating to a water-cleaning system and its toilet. Background Technology

[0002] The microbubble water technology currently used in smart toilets is mainly for cleaning the human body and the dirt inside the toilet ceramic.

[0003] Chinese utility model patent CN210767099U describes a microbubble generator connected in series in a water cooling system for human washing. However, while the microbubble device described in the patent operates on the same principle as a microbubble aerator in a faucet, in practical applications, when connected to the water system of a smart toilet as described in the patent, tests show that it cannot generate microbubbles with a diameter of less than 100 micrometers. The water that comes out contains ordinary small bubbles that dissipate immediately and cannot be sustained. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a more stable microbubble cleaning water system and a toilet using the cleaning water system.

[0005] The present invention adopts the following technical solution:

[0006] A water cleaning system includes a microbubble generator and a spray bar cleaning device. The spray bar cleaning device includes a spray bar and a self-cleaning mechanism for cleaning the spray bar. The outlet of the microbubble generator is connected to the inlet of the self-cleaning mechanism.

[0007] Microbubble generator generates microbubble water flow from the incoming water;

[0008] The self-cleaning mechanism includes a bubble water rinsing component. The bubble water rinsing component includes a rinsing seat and a mixing chamber disposed within the rinsing seat. The rinsing seat has a water inlet connected to a microbubble generator. The mixing chamber has a water outlet facing the upper surface of the spray bar and an air intake hole away from the water outlet. An acceleration hole with an inner diameter smaller than the inner diameter of the mixing chamber is disposed between the water inlet and the mixing chamber. The water flowing through the acceleration hole generates negative pressure in the mixing chamber, drawing air from the air intake hole and mixing to generate secondary bubbles.

[0009] Furthermore, the water inlet is arranged perpendicular to the acceleration hole, and the inner diameter of the water inlet is larger than the inner diameter of the acceleration hole.

[0010] Furthermore, there are two air intake holes, which are arranged vertically opposite each other on the rinsing seat.

[0011] Furthermore, the ratio of the flow area of ​​the intake hole to the flow area of ​​the acceleration hole is 0.5-2:1.

[0012] Furthermore, it also includes an anti-siphon component, which is connected to or disposed between the microbubble generator and the spray bar cleaning device.

[0013] Furthermore, it also includes a distribution valve, which is connected to the water outlet of the microbubble generator.

[0014] Furthermore, the microbubble generator includes an inlet cap and an outlet cap that is sealed to the inlet cap. The inlet cap includes an inlet cavity disposed therein, and the inlet cavity includes an inlet section and an expansion section arranged sequentially along the water flow direction. The inner diameter of the expansion section is larger than the inner diameter of the inlet section. The outlet cap communicates with the inlet and includes an outlet cavity disposed therein that communicates with the inlet cavity. The outlet cavity includes a connecting section that connects to the outer periphery of the inlet cap, a tapering section that communicates with the expansion section, and an outlet section.

[0015] Furthermore, the water outlet cavity also includes a squeezing section and a diversion section arranged sequentially between the converging section and the water outlet section, and the diversion section is provided with a plurality of diversion ribs arranged in a circle.

[0016] Furthermore, the expansion section includes a first expansion section and a second expansion section arranged sequentially along the water flow direction, wherein the inner diameter of the inlet section is smaller than the inner diameter of the first expansion section, and the inner diameter of the second expansion section is larger than the inner diameter of the first expansion section.

[0017] A toilet includes a toilet body and a cleaning water passage disposed in the toilet body as described in any of the above.

[0018] As can be seen from the above description of the present invention, compared with the prior art, the beneficial effects of the present invention are as follows: By defining the composition of the cleaning water path, the present application connects the microbubble generator with the self-cleaning mechanism, so that the treated water containing ultra-microbubbles after being treated by the microbubble generator can enter the bubble water rinsing component. The bubble water rinsing component causes the treated water containing ultra-microbubbles to generate a second large bubble water. Through the generation of bubble water twice, the surface of the spray bar is effectively treated. The large bubbles play a role in peeling off larger dirt on the surface of the spray bar, and the ultra-microbubbles play a role in powerfully cleaning and sterilizing the surface of the spray bar, thus having the advantages of both cleaning and sterilization.

[0019] Specifically, the structure of the microbubble water generator is defined, and the internal structure of the inlet cap and outlet cap is further defined, so that the water flowing in from one end of the inlet cap generates treated water containing ultra-microbubbles, and is discharged from the outlet section into the spray bar cleaning device for secondary bubble generation.

[0041] The present invention will be further described below through specific embodiments.

[0042] A toilet includes a toilet body and a cleaning water circuit disposed within the toilet body. The cleaning water circuit includes a microbubble generator 1, a spray bar cleaning device 2, a water inlet solenoid valve 3, a filter 4, an instant heating component 5, a UV sterilization component 6, a liquid pump 7, an anti-siphon component 8, and a distribution valve 9. The above components can be connected in various ways, such as... Figure 1 As shown, the inlet solenoid valve 3 is connected to external water, such as municipal water; the filter 4 is connected to the inlet solenoid valve 3; the instant heating component 5 is located between the UV sterilization component 6 and the filter 4; the liquid pump 7 is connected to the UV sterilization component 6; the anti-siphon component 8 is located between the liquid pump 7 and the microbubble water generator 1; and the distribution valve 9 is located between the microbubble water generator 1 and the spray bar cleaning device 2. The distribution valve 9 can also be connected to the toilet flushing system to send the treated water containing microbubbles generated by the microbubble water generator 1 into the toilet flushing system for microbubble water sterilization during toilet bowl washing. Specifically, the connection method of the cleaning water circuit in this application can also refer to... Figure 2The connections shown can be made by swapping the positions of the inlet solenoid valve 3 and the filter 4, and by swapping the positions of the UV sterilization component 6 and the liquid pump 7; the position of the anti-siphon component 8 can also be adjusted so that it is connected between the microbubble generator 1 and the spray bar cleaning device 2; the position of the distribution valve 9 can also be adjusted so that it is connected between the microbubble generator 1 and the anti-siphon component 8.

[0043] Reference Figures 3 to 4 As shown, the microbubble generator 1 includes a water inlet cover 11 and a water outlet cover 12 that is sealed to the water inlet cover 11, wherein the water inlet cover 11 and the water outlet cover 12 are sealed to each other by a sealing ring 13.

[0044] The water inlet cover 11 includes a water inlet cavity 111 disposed therein and an installation groove 112 disposed around its outer periphery for installing a sealing ring 13. The water inlet cavity 111 includes a water inlet section 113 and an expansion section arranged sequentially along the water flow direction. The expansion section includes a first expansion section 114 and a second expansion section 115 arranged sequentially, wherein the inner diameter of the first expansion section 114 is larger than the inner diameter of the water inlet section 113, and the inner diameter of the second expansion section 115 is larger than the inner diameter of the first expansion section 114. Specifically, the inner diameter ratio of the first expansion section 114 to the inlet section 113 is 1.2-2:1, and the inner diameter ratio of the second expansion section 115 to the first expansion section 114 is also 1.2-2:1. The inner diameter ratios of the first expansion section 114 to the inlet section 113 and the second expansion section 115 to the first expansion section 114 determine the overall slowing down level of the water flow after entering the expansion section. Generally speaking, the larger the ratio, the slower the speed, resulting in a more drastic change in the water flow pattern in the outlet cover 12, a higher bubble concentration, and a better effect. Furthermore, in order to maximize the flow rate per unit time, the preferred inner diameter of the inlet section 113 should not be less than 2 mm.

[0045] The water outlet cover 12 includes a water outlet cavity 121 disposed therein and communicating with the water inlet cavity 111. The water outlet cavity 121 includes a connecting section 122 that is sealed to the outer periphery of the water inlet cover 11, a tapering section 123 that communicates with the second expansion section 115, a water outlet section 126 that is arranged perpendicular to the tapering section 123, and a squeezing section 124 and a diverting section 125 that are sequentially disposed between the tapering section 123 and the water outlet section 126. The inner diameter of the tapering section 123 decreases sequentially along the water flow direction, the inner diameter of the squeezing section 124 is equal to the minimum inner diameter of the tapering section 123, and the inner wall of the connecting section 122 is sealed to the outer wall of the water inlet cover 11 by a sealing ring 13, so that the tapering section 123 and the second expansion section 115 are sequentially connected along the water flow direction. Specifically, the tapering section 123 is required to use a smooth transition curve to reduce the loss of fluid energy from the second expansion section 115 to the squeezing section 124.

[0046] The connection between the inlet cover 11 and the outlet cover 12 is as follows: The inlet cover 11 has multiple circumferentially distributed snap-fit ​​blocks 14 on its outer periphery. The connecting section 122 includes multiple circumferentially distributed snap-fit ​​grooves 15 on its inner wall and multiple circumferentially distributed clearance grooves 16 on the inner wall of the connecting section 122, each communicating with the first end of the multiple snap-fit ​​grooves 15. The clearance grooves 16 extend inward from the front end of the connecting section 122 along the water flow direction, and the snap-fit ​​grooves 15 extend circumferentially along the outlet section 126. When connected to the outlet cap 12, the sealing ring 13 is embedded in the mounting groove 112. Multiple snap-fit ​​blocks 14 are opposite to multiple clearance grooves 16. The inlet cap 11 is moved in the direction close to the outlet cap 12, causing the snap-fit ​​blocks 14 to enter the connecting section 122 through the corresponding clearance grooves 16. Then, the inlet cap 11 is rotated along the extension direction of the snap-fit ​​grooves 15, causing the snap-fit ​​blocks 14 to rotate into the corresponding snap-fit ​​grooves 15 and abut against the second end of the corresponding snap-fit ​​groove 15, completing the sealed connection between the inlet cap 11 and the outlet cap 12. Furthermore, the sealing ring 13 is located at the rear end of the multiple snap-fit ​​blocks 14 to ensure a sealed connection between the outlet cap 12 and the inlet cap 11.

[0047] In this application, the water outlet cover 12 has four embodiments, see reference. Figures 5 to 9 As shown, in the first embodiment of the water outlet cover 12 of this application, the water outlet section 126 and the diversion section 125 are arranged perpendicularly, and the diversion section 125 is provided with a plurality of diversion ribs 127 arranged in a circle. Two adjacent diversion ribs 127 form a diversion channel 120. During production, the number of diversion ribs 127 can be set according to production needs, so that the diversion channel 120 is arranged in a strip shape, a triangular shape, or a cross shape. Specifically, the diversion ribs 127 can be divided into many types and are not limited to the above-mentioned configurations.

[0048] Reference Figures 10 to 11 As shown, the second embodiment of the water outlet cover 12 of this application has a structure that is basically the same as that of the first embodiment. The difference is that: multiple swirling ribs 128 are provided in the tapered section 123. By setting multiple swirling ribs 128, the flow velocity of the water at the diversion ribs 127 is increased, thereby increasing the cutting and squeezing effect of the diversion ribs 127.

[0049] Reference Figures 12 to 13 As shown, the third embodiment of the water outlet cover 12 of this application has a structure that is basically the same as that of the first embodiment. The difference is that: multiple guide ribs 129 are provided in the tapered section 123. By providing multiple guide ribs 129, the water flow increases the rotational motion, thereby increasing the cutting and squeezing effect of the diversion ribs 127.

[0050] Reference Figures 14 to 16As shown in the fourth embodiment of the water outlet cover 12 of this application, the diversion section 125 is located at the front end of the water outlet section 126, and the diversion section 125 is provided with a plurality of circumferentially distributed diversion ribs 127, with adjacent diversion ribs 127 forming a diversion channel 120; during production, the number of diversion ribs 127 can be set according to production needs, so that the diversion channel 120 is arranged in different shapes. This embodiment can be applied to the microbubble generator 1 where the requirements for ultra-microbubble concentration and effect are not so high.

[0051] In addition, the length L of the extrusion section 124 also affects the overall flow rate and the density of microbubble generation. Generally speaking, the longer the extrusion section 124 is, the more stable the state when the water flow collides with the diversion ribs 127, which is less conducive to the generation of microbubbles, and the larger the flow rate. However, in order to reduce the overall flow resistance of the device and ensure that the outflow rate is not too much lower than the inflow rate, the extrusion section 124 still needs to maintain a certain length, that is, the ratio of the inner diameter of the inflow section 113 to the length of the extrusion section 124 is controlled within the range of 0.5-1.2:1. Furthermore, considering the actual system assembly and flow matching issues, the ratio of the inner diameter of the inflow section 113 to the inner diameter of the outflow section 126 is within the range of 0.8-1.2:1.

[0052] The working principle of the microbubble generator is as follows: Structurally, it utilizes the material of a Venturi tube. The overall internal water channel has an expansion-contraction-expansion structure. Water enters from one end of the inlet cover 11, and then undergoes two expansions through the first expansion section 114 and the second expansion section 115. The flow velocity decreases twice, becoming dispersed and turbulent. Then, it flows through the contraction section 123, where the water re-aggregates and the flow velocity increases. Before the diversion rib 127, the flow end face contracts again, causing a dramatic change in the liquid state and a further increase in flow velocity. At the same time, the water flow is accompanied by chaotic rotational motion, violently colliding in the area before the diversion rib 127, releasing dissolved oxygen in the water. Then, the water flow is squeezed and sheared after passing through the diversion rib 127, forming a vortex after the diversion rib 127. The flow end face expands at the rear end, further reducing the volume of bubbles in the water. Finally, the water containing ultra-microbubbles is discharged through the outlet section 126.

[0053] Reference Figures 17 to 20As shown, the spray bar cleaning device 2 includes a flusher 21, a spray bar 22 slidably mounted on the flusher 21, a drive mechanism for repeatedly sliding the spray bar 22 on the flusher 21, and a self-cleaning mechanism 23 located at the front end of the flusher 21. The water outlet section 126 of the water outlet cover 12 is connected to the flusher 21. Specifically, the self-cleaning mechanism 23 includes a mounting base 24 located at the front end of the flusher 21, a bubble water flushing assembly 25 detachably mounted on the mounting base 24, and a self-cleaning pipe 26 connected to the bubble water flushing assembly 25 on the mounting base 24. The treated water containing microbubbles enters the flusher 21 through the water outlet section 126 and then enters the bubble water flushing assembly 25 through the self-cleaning pipe 26, generating a second large bubble to achieve a double-bubble cleaning effect on the spray bar 22. Through the generation of bubble water twice, the microbubbles provide powerful cleaning and sterilization of the spray bar 22 surface, while the large bubbles remove larger dirt from the spray bar 22 surface, resulting in high cleaning efficiency.

[0054] The bubble water rinsing assembly 25 includes a rinsing seat 251 mounted on a mounting base 24, a mixing chamber 252 disposed in the rinsing seat 251 opposite to the upper surface of the spray bar 22, a water outlet 253 disposed on the rinsing seat 251 and facing the upper surface of the spray bar 22, communicating with the mixing chamber 252, a water inlet 254 disposed in the rinsing seat 251 and arranged perpendicularly to the mixing chamber 252, an acceleration hole 255 connecting the mixing chamber 252 and the water inlet 254, and two air intake holes 256 disposed vertically opposite each other on the rinsing seat 251 and connected to the mixing chamber 252. The ratio of the flow area of ​​the air intake hole 256 to the flow area of ​​the acceleration hole 255 is 0.5-2:1, and the flow area of ​​the acceleration hole 255 should not exceed 20 mm². 2 Specifically, to improve the cleaning effect of the bubble water rinsing assembly 25 on the spray bar 22, the extension line L1 of the water jet direction from the outlet 253 of the bubble water rinsing assembly 25 is defined, the impact point A where the water jet contacts the surface of the spray bar 22 is defined, and the tangent line L2 of the surface of the spray bar 22 in the extension direction of the spray bar 22 is drawn through the impact point A. The angle between L1 and L2 is defined as θ, where θ ≤ 90°. The larger the value of θ, the stronger the ability of the water flow to vertically impact the surface of the spray bar 22 and retain dirt. Considering the visual effect of the bubble water exiting from the front end of the rinsing, θ should not be too large and should be as small as possible. Its working principle is as follows: Utilizing the Venturi effect, air intake holes 256 are set on both opposite sides of the rear end of the acceleration hole 255 to draw air. After the gas and liquid phases mix in the mixing chamber 252 to generate a large number of bubbles, they are sprayed from the outlet 253 onto the surface of the spray bar 22 to achieve cleaning of the surface of the spray bar 22.

[0055] This application defines the structure of the microbubble water generator and the internal structure of the inlet cap 11 and the outlet cap 12. This allows the water flowing in from one end of the inlet cap 11 to generate treated water containing microbubbles, which is then discharged from the outlet section 126 into the spray bar cleaning device 2. The spray bar cleaning device 2 is equipped with a bubble water rinsing component 25. The bubble water rinsing component 25 causes the treated water containing microbubbles to generate a second large bubble. Through the generation of bubble water twice, the microbubbles play a role in powerfully cleaning and sterilizing the surface of the spray bar 22, while the large bubbles play a role in peeling off larger dirt from the surface of the spray bar 22, thus combining the advantages of cleaning and sterilization.

[0056] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
