Abstract
Description
Technical Field
[0001] This utility model relates to the field of sanitary ware technology, and in particular to a flushing nozzle and toilet. Background Technology
[0002] Foam shield technology is now widely used in toilets. It can suppress splashing, and the foam also has the functions of sterilization and deodorization, as well as lubrication to facilitate the discharge of waste.
[0003] In related technologies, foam shields are often generated using structures such as liquid pumps, air pumps, and bubble nets. The foam concentrate is mixed with water and air, and after passing through the bubble net to form bubbles, it is discharged into the water seal. However, the above devices occupy a large space. In order to save space, related technologies use flushing nozzles that use pressure difference to draw in air for foaming. However, the foaming effect of the above-mentioned flushing nozzles is poor. Utility Model Content
[0004] The purpose of this invention is to provide a flushing nozzle and toilet that can improve the foaming effect.
[0005] To achieve this objective, the present invention adopts the following technical solution:

The first main body has a first flow channel, and the second main body has a second flow channel. The first flow channel has a converging section with a gradually decreasing inner diameter, and the small diameter end of the converging section is located inside the second flow channel.
[0007] The blocking block is located inside the second flow channel and is spaced apart from the small-diameter end of the contraction section. The blocking block and the first main body have a jet nozzle that connects the first flow channel and the second flow channel, so that water can be ejected from the jet nozzle after hitting the blocking block.
[0008] The first main body is also provided with an inlet connected to the first flow channel, an outlet connected to the second flow channel, and an injection port connected to the first flow channel;
[0009] The second main body is provided with an air inlet that communicates with the second flow channel;
[0010] Multiple rectifying foaming elements are arranged circumferentially on the inner wall of the second flow channel and positioned between the spray nozzle and the water outlet.
[0011] In some embodiments, the blocking block is located on the central axis of the first flow channel;
[0012] And / or, multiple injection ports are provided, and the multiple injection ports are distributed circumferentially along the constriction section;
[0013] And / or, the injection port is located between the air inlet and the rectifier foaming element.
[0014] In some embodiments, the blocking block is connected to the first main body by connecting ribs spaced apart along the circumference of the blocking block, and the gap between adjacent connecting ribs is the injection port.
[0015] In some embodiments, the distance between the blocking block and the small-diameter end of the contraction section is 1mm-5mm.
[0016] In some embodiments, the first flow channel is further provided with a flow stabilizing section, which is connected to the large-diameter end of the contraction section, and the port of the flow stabilizing section away from the contraction section is the water inlet.
[0017] In some embodiments, a plurality of the rectifying foaming elements are evenly spaced along the inner wall of the second flow channel, and the plurality of the rectifying foaming elements form a central flow channel at one end away from the second flow channel.
[0018] In some embodiments, the second flow channel includes a jetting chamber section, a converging section, and a flow passage section connected in sequence. The jetting port is located in the jetting chamber section, the air inlet is disposed in the jetting chamber section, the rectifying foaming element is disposed in the flow passage section, the inner diameter of the converging section gradually decreases from the jetting chamber section to the flow passage section, the converging section is capable of receiving the water flow ejected from the jetting port, and the port of the flow passage section away from the jetting chamber section is the water outlet.
[0019] In some embodiments, the injection port is located in the contraction section and between the water inlet and the injection port.
[0020] In some embodiments, the flushing nozzle further includes an adjusting head connected to the water outlet to adjust the water outlet angle.
[0021] A toilet is also provided, the toilet including a raw liquid supply mechanism and a flushing nozzle as described above, the water inlet being connected to a water source, and the raw liquid supply mechanism being connected to the injection port.
[0022] The beneficial effects of this utility model are:
[0023] Water is supplied to the flushing nozzle through the inlet, and foaming liquid is supplied to the nozzle through the injection port. Since the injection port connects to the first flow channel, when the water flows from the inlet to the nozzle, the flow velocity increases and the pressure decreases as it passes through the contraction section. The foaming liquid injected through the injection port is rapidly mixed and carried away by the water flow, undergoing a primary mixing process. Due to the obstruction block and its distance from the small-diameter end of the contraction section, the water flow moves forward, detaching from the inner wall of the contraction section and converging towards the obstruction block. When the central water flow impacts the obstruction block, it slows down and stops flowing, forming a central high-pressure zone, while the surrounding area, which was originally detached from the construction block... The water flow converging towards the baffle block on the inner wall of the constricted section (low-pressure zone) will rebound and absorb energy for secondary acceleration upon contact with the high-pressure zone, then be ejected from the nozzle into the second flow channel, forming an outward-expanding water flow. During this impact, the mixing of water and foam concentrate is accelerated. Furthermore, the rapid change in water flow direction due to the rebound ejection creates an unstable, turbulent state, resulting in a discontinuous and non-dense surface, increasing the liquid's surface area. Simultaneously, the low pressure created in the second flow channel due to the Venturi effect draws air in through the air inlet. The secondary acceleration of the water flow intensifies the Venturi effect, drawing in more air. This increased flow pattern also expands the liquid's surface area, allowing more air to contact a unit volume of liquid, resulting in more uniform and thorough mixing and the formation of a foam liquid with richer foam, thus enhancing the foaming effect. Subsequently, due to the Coanda effect, most of the foam liquid flows at high speed along the inner wall of the second flow channel, while the velocity at the center of the channel is lower. When the foam liquid flows through the rectifying foaming components, due to the multiple rectifying foaming components arranged circumferentially... Placed on the inner wall of the second flow channel, it only acts on the high-speed water flow around the inner wall of the second flow channel. The high-speed foam liquid flow along the inner wall of the second flow channel will impact the rectifier foaming component. Under this action, the high-speed water flow around the inner wall will be further dispersed, and the foaming will be mixed and foamed again, further improving the foaming effect. At the same time, it will also reduce the water flow velocity around the inner wall, making it equal to the water flow velocity in the center of the second flow channel and merging them into one. This prevents the water flow towards the rectifier outlet from forming a "hollow" state, achieving a stable flow effect and thus forming stable foam water. Attached Figure Description

[0044] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0045] like Figures 1 to 8 As shown, this utility model provides a flushing nozzle 10, which includes a nozzle body 1. The nozzle body 1 includes a first main body portion 11, a second main body portion 12, a blocking block 13, and a rectifying foaming component 14. The first main body portion 11 has a first flow channel 111, and the second main body portion 12 is provided with a second flow channel 121. The first flow channel 111 is provided with a converging section 111a with a gradually decreasing inner diameter. The small-diameter end of the converging section 111a is located inside the second flow channel 121. The blocking block 13 is located inside the second flow channel 121 and is spaced apart from the small-diameter end of the converging section 111a. The blocking block 13 is located within the first main body portion 111. The first main body 11 has a nozzle 15 connecting the first flow channel 111 and the second flow channel 121, so that the water flow in the contraction section 111a can hit the blocking block 13 and be sprayed out from the nozzle 15 to the second flow channel 121; the first main body 11 is also provided with a water inlet 16 connecting the first flow channel 111, a water outlet 19 connecting the second flow channel 121 and a liquid injection port 17 connecting the first flow channel 111; the second main body 12 is provided with an air inlet 18 connecting the second flow channel 121; a plurality of rectifier foaming elements 14 are arranged circumferentially on the inner wall of the second flow channel 121 and are arranged between the nozzle 15 and the water outlet 19.
[0046] Using the aforementioned flushing nozzle 10, water is supplied to the flushing nozzle 10 through the inlet 16, and foaming liquid is supplied to the flushing nozzle 10 through the injection port 17. Since the injection port 17 is connected to the first flow channel 111, when the water flows from the inlet 16 to the spray port 15, the water flow velocity increases and the pressure decreases when passing through the contraction section 111a. The foaming liquid injected through the injection port 17 will quickly mix with the water flow, undergoing a single mixing. Because the blocking block 13 is spaced from the small-diameter end of the contraction section 111a, the water flow will detach from the inner wall of the contraction section 111a and converge towards the blocking block 13. When the central water flow hits the blocking block 13, it will slow down and stop flowing, forming a central high-pressure zone 4. The water flow that originally detached from the inner wall of the contraction section 111a and converged towards the blocking block 13 (low-pressure zone 3) will, upon contact with the high-pressure zone 4 (e.g., Figure 7 As shown), the water rebounds and absorbs energy for secondary acceleration, ejecting from nozzle 15 into the second flow channel 121, forming an outward-expanding water flow. During this impact, the mixing of water and foam concentrate is accelerated. Furthermore, the rapid change in water flow direction due to the rebound ejection creates an unstable, turbulent state, resulting in a discontinuous and non-dense surface, increasing the liquid's surface area. Simultaneously, the Venturi effect creates low pressure within the second flow channel 121, drawing air in through the air inlet 18. The secondary acceleration further intensifies the Venturi effect, drawing in even more air. This increased surface area means more air per unit volume, leading to more uniform and thorough mixing, resulting in a richer foam concentrate and improved foaming effect. Subsequently, due to the coanda of the liquid… Due to the effect, most of the foam liquid will flow at high speed along the inner wall of the second flow channel 121, while the speed at the center of the second flow channel 121 will be lower. When the foam liquid flows through the rectifying foaming element 14, since multiple rectifying foaming elements 14 are arranged circumferentially on the inner wall of the second flow channel 121, it only acts on the high-speed water flow around the inner wall of the second flow channel 121. The foam liquid flowing at high speed along the inner wall of the second flow channel 121 will hit the rectifying foaming element 14 and flow out from the outlet 19. Under this action, the high-speed water flow around the perimeter is further dispersed, and the mixture is foamed again, further improving the foaming effect. At the same time, it will also reduce the water flow velocity around the inner wall, making it equal to the water flow velocity at the center of the second flow channel 121 and merging into one. Thus, the water flow towards the rectifying outlet will not form a "hollow" state, achieving a stable flow effect, thereby forming stable foam water.
[0047] It should be noted that "hollow" water flow also generates air noise. Reducing the "hollow" water flow can further suppress water output noise, thus achieving a noise reduction effect. At the same time, placing the injection port 17 in the contraction section 111a allows the injected foaming liquid to be quickly carried away by the rapid water flow, reducing residue.
[0048] like Figure 2 and Figure 3 As shown, in some embodiments, the blocking block 13 is located on the central axis of the first flow channel 111, so that all the water flow gathered in the contraction section 111a flows towards the blocking block 13. This ensures that when the water flow impacts the blocking block 13, the high-pressure zone 4 is located as close as possible to the center of the first flow channel 111, thereby enhancing the impact effect. Correspondingly, multiple nozzles 15 can be provided, distributed circumferentially along the blocking block 13, so that the water flow can quickly enter the second flow channel 121 after impact. In the current embodiment, four nozzles 15 are preferably used, evenly spaced. Too many or too few nozzles 15 will affect the water flow rate.
[0049] like Figure 3 As shown, specifically, in order to fix the blocking block 13 and facilitate the formation of the spray nozzle 15, the blocking block 13 and the first main body 11 are connected by connecting ribs that are spaced apart along the circumference of the blocking block 13. One end of the connecting rib is connected to the blocking block 13, and the other end is connected to the first main body 11. The gap between adjacent connecting ribs is the spray nozzle 15. In the current embodiment, the blocking block 13, the connecting ribs, and the first main body 11 are integrally formed, which facilitates manufacturing.
[0050] It is understood that by adjusting the angle between the axis of the contraction section 111a and the axis of the first flow channel 111 (that is, the angle of the inclined surface of the contraction section 111a), the rebound angle of the water flow hitting the blocking block 13 can be adjusted, thereby adjusting the spray angle of the water flow along the nozzle 15. In the current embodiment, the angle between the axial line of the contraction section 111a and the first flow channel 111 can be, but is not limited to, 30° to 60°, so that the water flow can rebound smoothly and be sprayed out from the nozzle 15.
[0051] In some embodiments, the distance between the blocking block 13 and the small-diameter end of the contraction section 111a is 1mm-5mm, and the current embodiment uses 2mm, thereby forming a rebound gap. The rebound gap should not be too large or too small. If it is too large, the central pressure will be insufficient and the water flow rebound effect will not be obvious. If it is too small, the central high pressure section will be short and easily blocked by the wall of the contraction section 111a, so that it cannot rebound or the amount of water rebounded is small.
[0052] In some embodiments, the first flow channel 111 is further provided with a flow stabilizing section 111b, which is connected to the large-diameter end of the contraction section 111a. The port of the flow stabilizing section 111b away from the contraction section 111a is the aforementioned inlet 16. The flow stabilizing section 111b is provided upstream of the contraction section 111a to stabilize the water flow before it enters the contraction section 111a, so that the water flow can flow steadily towards the blocking block 13 along the contraction section 111a, reducing the formation of turbulence before impact and reducing the impact on water flow acceleration and water flow impact.
[0053] like Figure 2 and Figure 3 As shown, in some embodiments, a gap is provided between the first main body 11 and the second main body 12 located in the contraction section 111a to facilitate air intake through the air inlet 18. The air inlet 18 is opposite to the contraction section 111a, and air flows into the second flow channel 121 through the air inlet 18 and the aforementioned gap. Furthermore, in the current embodiment, the spray nozzle 15 is located between the air inlet 18 and the rectifier foaming member 14, so that the water flow sprayed from the spray nozzle 15 is downstream of the air inlet 18, thereby reducing the probability of the sprayed water flow exiting through the air inlet 18 and also reducing the possibility of the water flow obstructing the air intake through the air inlet 18. Of course, in the current embodiment, the distance between the spray nozzle 15 and the air inlet 18 is less than the distance between the spray nozzle 15 and the rectifier foaming member 14, meaning the spray nozzle 15 is closer to the air inlet 18, thus facilitating air intake.
[0054] In the current embodiment, the injection port 17 is located in the contraction section 111a and between the water inlet 16 and the spray port 15. When the water flows from the water inlet 16 to the spray port 15, the water flow velocity increases and the pressure decreases when passing through the contraction section 111a, which allows the foaming agent to mix better with the water flow.
[0055] Since a gap is provided between the first main body 11 and the second main body 12 located in the contraction section 111a, and in order to facilitate the placement of the injection port 17 in the contraction section 111a, in the current embodiment, the flushing nozzle 10 also includes a connector, which passes through the second main body 12 and connects to the first main body 11, and the injection port 17 is formed on the connector.
[0056] In some embodiments, to better receive the water flow ejected from the nozzle 15, the second flow channel 121 includes a jet chamber section 121a, a converging section 121b, and a flow passage section 121c connected in sequence. The nozzle 15 is located in the jet chamber section 121a, the air inlet 18 is located in the jet chamber section 121a, and the port of the flow passage section 121c away from the jet chamber section 121a is the water outlet 19. The converging section 121b can receive the water flow ejected from the nozzle 15, so that when the water flow ejected from the nozzle 15 passes through the jet chamber section 121a and the air entering through the air inlet 18, the water flow is fully condensed in the jet chamber section 121a. The mixture forms foamy water, which then impacts the converging section 121b. The inner diameter of the converging section 121b gradually decreases from the spray chamber section 121a to the flow channel section 121c (forming a funnel mouth). The foamy water enters the flow channel section 121c under the converging effect of the converging section 121b. During this period, most of the foam liquid will flow at high speed along the inner wall of the second flow channel 121, while the speed at the center of the flow channel section 121c will be lower. The rectifier foaming element 14 is set in the flow channel section 121c to disperse the water flow adhering to the wall, reducing the "hollow" water flow, and then flows out from the outlet 19.
[0057] In the current embodiment, multiple rectifier foaming components 14 are evenly spaced along the inner wall of the second flow channel 121, and the multiple rectifier foaming components 14 form a central flow channel at the end away from the second flow channel 121. This allows the rectifier foaming components 14 to disperse the water flow attached to the wall while reducing the impact on the central water flow, and to re-mix and foam when dispersing the water flow attached to the wall, thereby further improving the foaming effect.
[0058] It should be noted that in the current embodiment, the rectifier foaming component 14 is a rectangular block, and several rectangular blocks are distributed at intervals along the inner wall of the flow channel section 121c.
[0059] like Figure 4 and Figure 5 As shown, for ease of molding, in some embodiments, the second main body 12 includes a detachable first portion 122 and a second portion 123, wherein the spraying chamber section 121a is formed on the first portion 122, and the converging section 121b and the flow channel section 121c are formed on the second portion 123, so that the first portion 122 can be integrally molded with the connector and the first main body 11; while the rectifying foaming component 14 can be separately molded with the second portion 123 for ease of manufacturing. It is understood that in other alternative embodiments, the first main body 11 and the second main body 12 can be integrally molded. Exemplarily, the first portion 122 and the second portion 123 can be connected by, but not limited to, snap-fit, screw connection, or other methods.
[0060] In some embodiments, in order to adjust the path of the foam water coming out of the second flow channel 121, the flushing nozzle 10 also includes an adjusting head 2, which is connected to the water outlet 19 to adjust the water outlet angle. The adjusting head 2 is a commonly used water outlet adjusting head in the prior art, and its specific structure will not be described in detail.
[0061] like Figure 8 As shown, this utility model also provides a toilet, which includes a ceramic body 20, a water tank 30, a raw material supply mechanism 40, and the aforementioned flushing nozzle 10. The ceramic body 20 has a pot surface 201, wherein the water tank 30 is connected to the water inlet 16 of the flushing nozzle 10 to supply water flow thereto; in other embodiments, the water inlet 16 can also be directly connected to the municipal water outlet, thus eliminating the need for a water tank 30; the raw material supply mechanism 40 is connected to the injection port 17 to supply foam raw material thereto; the adjusting head 2 faces the pot surface 201, thereby supplying liquid to the pot surface 201 to form a foam shield. It is understood that the aforementioned flushing nozzle 10 can also be used in other devices for generating foam.
[0062] It should be noted that when in use, supplying both water and foam concentrate to the rinsing nozzle 10 simultaneously can form a foam shield; while during washing, water can also be supplied to the rinsing nozzle 10 alone without foam concentrate. In this case, the rinsing nozzle 10 can provide abundant bubbly water to the pot surface 201 through secondary acceleration of the water flow and thorough mixing with air. The bubbles in the bubbly water can burst on the pot surface 201, generating a very small liquid jet and shock wave, which can loosen and disturb the loose dirt attached to the pot surface 201, further improving the washing efficiency.
[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
