Technical Field

[0001] The present application is applied to the technical field of smart bathrooms, and in particular relates to a foaming nozzle and a smart toilet. Background Art

[0002] With the improvement of living standards, smart toilets have been widely used. In order to make the toilet splash-proof, anti-sticky, anti-odor and antibacterial when in use, it is often necessary to use "foam shield" technology.

[0003] However, most existing foam shields are external independent modules, which require multiple pumps and separate foam spraying devices during use, and have high use and maintenance costs. Since the external foam shield contains many components, it will also occupy the limited installation space of the smart toilet. The existing side-flush foaming nozzle has a complex structure and requires a large installation space. In addition, since the air intake does not meet the requirements, the side-flush foaming stability of the pumpless or single-pump nozzle is poor. Utility Model Content

[0004] The present application provides a foaming nozzle to solve the problems of poor foaming stability and large occupied space in the prior art.

[0005] In order to solve the above-mentioned technical problems, the first aspect of the present application provides a foaming nozzle, including: a nozzle, a accommodating space is formed in the nozzle, a foaming outlet connected to the accommodating space is formed on one side of the nozzle, and a water inlet channel connected to the accommodating space is formed on the other side of the nozzle, and the opening of the accommodating space gradually increases near the foaming outlet; a clamping part, a liquid inlet channel is formed in the clamping part; wherein a liquid inlet connected to the accommodating space is provided on the side wall of the nozzle, the clamping part is clamped on the nozzle, and the liquid inlet channel is connected to the liquid inlet.

[0006] The water inlet channel is located at a side of the accommodating space away from the foaming outlet, and a spiral member is arranged in the water inlet channel.

[0007] Wherein, the connection portion of the water inlet channel close to the accommodating space is set as a tapered structure, and the opening close to the accommodating space gradually decreases.

[0008] The foaming nozzle further comprises: a foam liquid box and a liquid pump, the foam liquid box and the liquid pump are connected via a pipeline, and the liquid pump is connected to the liquid inlet channel.

[0009] Wherein, a slot matching with the clamping piece is provided on the side wall of the nozzle, and the clamping piece is clamped in the slot.

[0010] Among them, a limiting piece is arranged on the side wall of the slot away from the liquid inlet; a buckle is arranged on the clamping piece, and the buckle is clamped with the limiting piece to limit the liquid inlet channel.

[0011] The foaming nozzle further comprises a sealing ring which is arranged in the liquid inlet and is clamped by the liquid inlet channel and the nozzle.

[0012] Wherein, at least one air inlet connected with the accommodating space is provided on the side wall of the nozzle.

[0013] Among them, a foaming claw is arranged in the foaming outlet; and a liquid separation valve is arranged at one end of the water inlet channel away from the accommodating space.

[0014] To solve the above problems, the present application also provides a smart toilet, including: a nut, the nut is threadedly connected to the side wall of the foaming nozzle to clamp the foaming nozzle on the side wall of the smart toilet, and the foaming nozzle is any one of the foaming nozzles mentioned above.

[0015] The beneficial effect of the present application is as follows: different from the prior art, the present application forms a accommodating space in the nozzle, opens a liquid inlet on the side wall of the nozzle, so that the liquid inlet channel is connected with the liquid inlet, and the foaming liquid can enter the accommodating space through the liquid inlet channel and the liquid inlet. After the water flows into the accommodating space through the water inlet channel, the speed at which the water flows into the accommodating space decreases due to the gradual increase in the opening of the accommodating space close to the foaming outlet. The foam liquid, air and water flow can be completely mixed inside the accommodating space, which effectively improves the foaming efficiency of the foam liquid. The clamping piece is clamped to the side wall of the nozzle, which effectively reduces the cost of using and maintaining the foam nozzle and the volume of the foam nozzle, thereby solving the problem of large installation space requirement for the foam nozzle.

[0027] The present application provides a foaming nozzle. Figure 1As shown, the foaming nozzle of this embodiment includes a nozzle 10 and a clamping part 20. A containing space 101 is formed in the nozzle 10, a foaming outlet 102 connected to the containing space 101 is formed on one side of the nozzle 10, and a water inlet channel 103 connected to the containing space 101 is formed on the other side of the nozzle 10, and the opening of the containing space 101 gradually increases near the foaming outlet 102. Among them, the containing space 101 can be set as a conical structure, or other structures that gradually increase near the foaming outlet 102, which is not specifically limited in this application. A liquid inlet channel 201 is formed in the clamping part 20. The accommodating space 101 is used for foaming of foam liquid. The foam liquid enters the accommodating space 101 through the liquid inlet channel 201 in the clamping member 20. At the same time, the water in the water inlet channel 103 enters the accommodating space 101 and mixes with the foam liquid to foam in the accommodating space 101. After the foaming is completed, the foamed foam is sprayed out through the foaming outlet 102 of the nozzle 10. The liquid inlet channel 201 can be a pipe. The side wall of the nozzle 10 is provided with a liquid inlet 104 connected to the accommodating space 101. The clamping member 20 is clamped on the nozzle 10 and connects the liquid inlet channel 201 with the liquid inlet 104. The clamping member 20 is elastic and can be set to a semicircular ring in the shape of an arc, so as to facilitate plugging and unplugging and clamping or detaching the nozzle 10. It can also be set to other shapes that fit the side wall of the nozzle 10. The shape of the clamping member 20 can be determined according to the shape of the side wall of the nozzle 10, and the present application does not make specific restrictions here.

[0028] In an optional embodiment, if Figure 1 As shown, a containing space 101 is formed in the nozzle 10, and a liquid inlet 104 communicating with the containing space 101 is provided in the containing space 101, and the foaming liquid can enter the containing space 101 through the liquid inlet 104. By clamping the clamping member 20 on the side wall of the nozzle 10, the liquid inlet channel 201 is communicated with the liquid inlet 104, so that the foaming liquid can enter the containing space 101 through the liquid inlet channel 201 and the liquid inlet 104, and foaming can be performed in the containing space 101. A water inlet channel 103 communicating with the containing space 101 is formed on the other side of the nozzle 10, and water can enter the containing space 101 through the water inlet channel 103. After the water flow and the foam liquid enter the accommodating space 101, the opening of the accommodating space 101 close to the foaming outlet 102 gradually increases, that is, as the flow direction of the water flow gradually expands, the speed of the water flow decreases, and the foam liquid, air and water flow can be completely mixed in the accommodating space 101, effectively improving the foaming efficiency of the foam liquid and the consumption of the foaming liquid. A foaming outlet 102 connected to the accommodating space 101 is formed on one side of the nozzle 10. After the foam liquid is completely foamed in the accommodating space 101, the foamed foam is sprayed out through the foaming outlet 102 by the water flow.

[0029] Further, the clamping member 20 is clamped on the nozzle 10, that is, the clamping member 20 is detachably connected to the side wall of the nozzle 10, and the clamping member 20 can be removed or clamped on the nozzle 10 by plugging and unplugging. For example, when the user needs to pass the foam liquid into the accommodating space 101 through the liquid inlet channel 201, the clamping member 20 can be inserted into the side wall of the nozzle 10, so that the liquid inlet channel 201 is connected with the liquid inlet port 104 opened on the side wall of the nozzle 10, and the foam liquid can pass into the accommodating space 101 through the liquid inlet channel 201 and the liquid inlet port 104. Conversely, when the user needs to stop the foaming of the foam liquid, the clamping member 20 clamped on the side wall of the nozzle 10 can be pulled out, so as to remove the clamping member 20 with the liquid inlet channel 201. When the nozzle 10 or the clamping member 20 fails, the nozzle 10 and the clamping member 20 can be repaired by disassembling the clamping member 20. That is, by plugging the clamping part 20 with the liquid inlet channel 201 onto the side wall of the nozzle 10 by plugging and unplugging, the foaming and flushing are combined, and only one pump is needed to complete the flushing and foaming. On the one hand, the cost of using and maintaining the foam nozzle 10 is effectively reduced. On the other hand, the liquid inlet channel 201 for the foam liquid is directly plugged into the side wall of the nozzle 10, which effectively reduces the volume of the foam nozzle 10. When the foam nozzle 10 is installed, it will not occupy the internal space of the product, which is convenient for the installation of the foam nozzle and the layout of the components in the product.

[0030] In the above embodiment, by forming a receiving space 101 in the nozzle 10 and opening a liquid inlet 104 on the side wall of the nozzle 10, the liquid inlet channel 201 is connected with the liquid inlet 104, and the foaming liquid can enter the receiving space 101 through the liquid inlet channel 201 and the liquid inlet 104. After the water flows into the receiving space 101 through the water inlet channel 103, the speed of the water flowing into the receiving space 101 decreases due to the gradual increase of the opening of the receiving space 101 close to the foaming outlet 102, and the foam liquid, air and water flow can be completely mixed in the receiving space 101, which effectively improves the foaming efficiency of the foam liquid. In addition, the clamping member 20 is clamped on the side wall of the nozzle 10, that is, the foaming and flushing are combined to reduce the volume of the foaming nozzle, effectively reduce the cost of using and maintaining the foam nozzle 10 and the volume of the foam nozzle 10, and solve the problem of large installation space requirements for the foam nozzle 10.

[0031] In an optional embodiment, the water inlet channel 103 is located on a side of the accommodating space 101 away from the foaming outlet 102, and a spiral member 30 is arranged in the water inlet channel 103. Among them, a groove can be arranged in the water inlet channel 103, and a rib can be arranged on the spiral member 30. The rib and the groove cooperate with each other to achieve the effect of fixing the spiral member 30 inside the water inlet channel 103. The spiral angle can also be fixed inside the water inlet channel 103 by welding or bonding. The present application does not make specific limitations here. By setting the water inlet channel 103 on a side of the accommodating space 101 away from the foaming outlet 102, and setting the spiral member 30 inside the water inlet channel 103, after the water flow enters the water inlet channel 103, the water flow will form a spiral water flow. When the spiral water flow enters the accommodating space 101, it can effectively promote the mixing of the foam liquid, air and water flow. So that the foaming efficiency of the foam liquid is further improved. Furthermore, in this embodiment, if Figure 1 As shown, the connection portion of the water inlet channel 103 near the accommodating space 101 is set as a tapered structure 301, and the opening near the accommodating space 101 gradually decreases. That is, after the water flow is formed into a spiral water flow by the spiral member 30, since the connection portion of the water inlet channel 103 and the accommodating space 101 is set as a tapered structure 301 with a gradually decreasing opening near the accommodating space 101, when the water flow enters the accommodating space 101, that is, the cross-sectional area of ​​the water flow at the connection portion of the water inlet channel 103 and the accommodating space 101 gradually decreases, the flow speed of the water flow will gradually increase, and the accelerated spiral water flow is rapidly ejected into the accommodating space 101, which effectively increases the air intake of the accommodating space 101, thereby improving the foaming efficiency of the foam liquid.

[0032] In an optional embodiment, if Figure 2As shown, the foaming nozzle also includes: a foam liquid box 401 and a liquid pump 402, the foam liquid box 401 and the liquid pump 402 are connected through a pipeline, and the liquid pump 402 is connected to the liquid inlet channel 201. Among them, the input end of the liquid pump 402 is connected to the foam liquid box 401, and the output end of the liquid pump 402 is connected to the clamping member 20, that is, the output end of the liquid pump 402 is connected to the liquid inlet channel 201. Therefore, when it is necessary to foam through the foaming nozzle, the liquid pump 402 extracts the foam liquid in the foam liquid box 401 through the pipeline, and transmits it to the inside of the accommodating space 101 through the liquid inlet channel 201, and the liquid pump 402 is directly connected to the foam liquid box 401 and the nozzle 10, which effectively reduces the volume of the foaming nozzle during installation, and can reduce the problem of insufficient layout space for the product. In this embodiment, when the user uses the foam nozzle 10 to foam the foam liquid, the user connects the clamping piece 20 to the side wall of the nozzle 10, uses the liquid pump 402 to extract the foam liquid in the foam liquid box 401 and transmits it to the interior of the accommodating space 101 through the liquid inlet channel 201, and inputs the water flow into the interior of the accommodating space 101 through the water inlet channel 103 to mix with the foam liquid, thereby completing the foaming of the foam liquid. After the foaming is completed, the completed foam is sprayed out through the foaming outlet 102 of the nozzle 10.

[0033] In an optional embodiment, a slot 50 adapted to the clamping member 20 is provided on the side wall of the nozzle 10, and the clamping member 20 is clamped in the slot 50. Figure 3 As shown, the clamping member 20 takes an arc-shaped semicircular ring as an example, and a clamping groove 50 is opened on the side wall of the nozzle 10. When the clamping member 20 is clamped on the nozzle 10, the clamping member 20 is clamped inside the clamping groove 50, thereby preventing the clamping member 20 from sliding on the side wall of the nozzle 10 along the axial direction of the nozzle 10, that is, the clamping member 20 is limited by the clamping groove 50 to prevent the clamping member 20 from sliding so that the liquid inlet channel 201 and the liquid inlet port 104 are misaligned, thereby causing the foam liquid to leak or the liquid inlet channel 201 to be blocked. Furthermore, in order to further prevent the foam liquid from leaking when it is transmitted to the accommodating space 101, in this embodiment, as Figure 4 As shown, the foaming nozzle also includes a sealing ring 60, which is arranged in the liquid inlet 104, and the sealing ring 60 is clamped by the liquid inlet channel 201 and the nozzle 10. That is, when installing the foaming nozzle, the sealing ring 60 is installed inside the liquid inlet 104, and the clamping member 20 is inserted on the side wall of the nozzle 10, and the clamping member 20 clamps the sealing ring 60 inside the liquid inlet 104, that is, clamps the nozzle 10 through the liquid inlet channel 201 of the clamping member 20, so as to prevent the sealing ring 60 from being misplaced. In other embodiments, the sealing ring 60 can be bonded inside the liquid inlet 104 of the nozzle 10, so as to prevent the sealing ring 60 from falling off when the clamping member 20 is disassembled, and the sealing ring 60 can also be bonded at the outlet of the liquid inlet channel 201 of the clamping member 20, which is not specifically limited in this application.

[0034] In an optional embodiment, if Figure 5 As shown, a limiting member 501 is provided on the side wall of the card slot 50 away from the liquid inlet 104. A buckle 202 is provided on the card connector 20, and the buckle 202 is engaged with the limiting member 501 to limit the liquid inlet channel 201. By providing the limiting member 501 on the card slot 50, the card connector 20 can be limited, that is, the card connector 20 is engaged in the card slot 50, and the buckle 202 on the card connector 20 is engaged with the limiting member 501, that is, the limiting member 501 and the buckle 202 cooperate with each other. When the card connector 20 is engaged in the card slot 50, the buckle 202 is effectively prevented from shaking when it is engaged in the card slot 50, so that a gap appears between the liquid inlet channel 201 of the card connector 20 and the liquid inlet 104, so that when the foam liquid is transported to the inside of the accommodating space 101, the foam liquid overflows through the gap, thereby causing unstable foaming of the foam liquid. When the clamping member 20 and the nozzle 10 are disassembled, the clamping member 20 is pulled out so that the buckle 202 is disengaged from the limiting member 501 , and thus the clamping member 20 is disengaged from the inside of the clamping slot 50 .

[0035] In an optional embodiment, at least one air inlet 70 communicating with the accommodating space 101 is provided on the side wall of the nozzle 10. Figure 3 As shown, the air inlet 70 is arranged at the connection between the nozzle 10 and the foaming outlet 102, that is, the end of the first accommodating space 101 close to the foaming outlet 102. The air inlet 70 can be evenly arranged around the connection between the nozzle 10 and the foaming outlet 102, or relatively arranged on the side wall of the nozzle 10. The number of the air inlet 70 can be set as needed, and this application does not make a specific limitation here. That is, by providing at least one air inlet 70 connected to the accommodating space 101 on the nozzle 10, when the foaming nozzle is foaming, the foam liquid in the foam liquid box 401 is transported to the accommodating space 101 through the liquid pump 402, and the water flow in the water inlet channel 103 is transformed into a spiral water flow under the action of the spiral member 30. The spiral water flow passes through the water inlet channel 103 and the conical structure 301 near the connection part of the accommodating space 101, and the spiral water flow accelerates and impacts into the accommodating space 101. After the spiral water flow enters, the air intake of the air inlet 70 is effectively increased due to the high water flow speed, so that the water flow, air and foam liquid are completely mixed. That is, by providing at least one air inlet 70 connected to the accommodating space 101, when the water flow speed is too high, the air intake is effectively increased, so that the foaming efficiency and stability of the foam liquid are effectively improved.

[0036] In an optional embodiment, if Figure 2 and Figure 4As shown, a foaming claw 80 is provided in the foaming outlet 102, and a liquid separation valve 90 is provided at one end of the water inlet channel 103 away from the accommodating space 101. The foaming claw 80 can be clamped in the foaming outlet 102 of the nozzle 10, or fixed in the foaming outlet 102 by welding or pasting, etc., and the present application does not make specific restrictions here. Therefore, after the foam liquid in the accommodating space 101 is completely mixed to become foam, when it is ejected through the foaming outlet 102 of the nozzle 10 under the impact of the water flow, the foam will pass through the foaming claw 80, and under the action of the foaming claw 80, the foam can be completely broken, so that the ejected foam becomes uniform. A liquid separation valve 90 is provided at one end of the water inlet channel 103 away from the accommodating space 101, and the water flow can enter the inside of the water inlet channel 103 through the liquid separation valve 90. Among them, the liquid separation valve 90 can be connected to the end of the water inlet channel 103 by a nut, or it can be connected by welding, and the present application does not make specific restrictions here.

[0037] In a specific embodiment, Figure 4 As shown, when installing the clamping member 20 of the foaming nozzle, the sealing ring 60 is fixed in the water inlet of the nozzle 10, and the clamping member 20 is clamped on the side wall of the nozzle 10. That is, the clamping member 20 is inserted into the slot 50 on the side wall of the nozzle 10, and the buckle 202 on the clamping member 20 is buckled on the limiting member 501 of the slot 50 away from the liquid inlet 104, so as to limit the clamping member 20 to prevent the clamping member 20 from shaking on the nozzle 10 and the situation of unstable clamping. When using the foaming nozzle, the liquid pump 402 extracts the foam liquid in the foam liquid box 401 and transports it to the inside of the accommodating space 101 through the liquid inlet channel 201 and the liquid inlet 104. At this time, the water flow inside the liquid separation valve 90 enters the water inlet channel 103, and under the action of the spiral member 30 inside the water inlet channel 103, the water flow will become a spiral water flow. When the spiral water flow passes through the conical structure 301 at the connection position between the water inlet channel 103 and the accommodating space 101, the spiral water flow will accelerate into the accommodating space 101. Under the action of the fast spiral water flow, the air intake of the air inlet 70 increases. At this time, the foam liquid flows in the accommodating space 101 toward the foaming outlet 102 under the promotion of the spiral water flow. As the opening of the accommodating space 101 close to the foaming outlet 102 gradually increases, the speed of the water flow decreases, and the foam liquid, air and water flow can be completely mixed inside the accommodating space 101, which effectively improves the foaming efficiency of the foam liquid. In a specific embodiment, Figure 4 As described above, the nozzle 10 is threadedly connected with a first nut 105, and the foaming nozzle can be clamped on the product by setting the first nut 105, that is, the foaming nozzle is fixed by the first nut 105. Figure 2 and Figure 4 The nozzle 10 is also threadedly connected with a second nut 106, and the second nut 106 is used to fix the liquid separator 90 at the end of the nozzle 10 away from the foaming outlet 102.

[0038] In the above manner, the present application forms a gradually increasing accommodating space 101 near the foaming outlet 102 in the nozzle 10, and clamps the clamping member 20 on the side wall of the nozzle 10, so that the liquid inlet channel 201 is connected to the liquid inlet 104, which can reduce the speed of water entering the accommodating space 101, and the foam liquid, air and water flow can be completely mixed inside the accommodating space 101, effectively improving the foaming efficiency of the foam liquid, and reducing the cost of using and maintaining the foam nozzle 10 and the volume of the foam nozzle 10. By setting the water inlet channel 103 on the side of the accommodating space 101 away from the foaming outlet 102, and setting the spiral member 30 in the water inlet channel 103, the water flow can be formed into a spiral water flow when entering the water inlet channel 103, effectively promoting the mixing of the foam liquid, air and water flow. By setting the connection part between the water inlet channel 103 and the accommodating space 101 as a tapered structure 301 whose opening is gradually reduced near the accommodating space 101, the water flow cross-sectional area of ​​the connection part between the water inlet channel 103 and the accommodating space 101 can be gradually reduced to increase the flow velocity of the water flow, effectively increase the air intake of the accommodating space 101, and thus improve the foaming efficiency of the foam liquid. By setting a liquid pump 402 connected to the liquid inlet channel 201 and a foam liquid box 401 connected to the liquid pump 402, the volume of the foaming nozzle during installation is effectively reduced, and the problem of insufficient layout space for the product can be reduced. By providing a slot 50 adapted to the clamping member 20 on the side wall of the nozzle 10, and clamping the clamping member 20 in the slot 50, the clamping member 20 can be prevented from sliding on the side wall of the nozzle 10 along the axial direction of the nozzle 10, so that the liquid inlet channel 201 and the liquid inlet 104 are misaligned. By providing a sealing ring 60 in the liquid inlet 104, leakage of the foam liquid when being transferred to the accommodating space 101 is effectively prevented. By providing a limiter 501 on the side wall of the card slot 50 away from the liquid inlet 104, and providing a limiter 501 on the clamping member 20, the clamping member 20 can be limited, so that a gap between the liquid inlet channel 201 and the liquid inlet 104 is prevented, thereby causing the foam liquid to overflow. By providing at least one air inlet 70 connected to the accommodating space 101 on the side wall of the nozzle 10, the air intake volume can be increased under the action of the water flow, so that the water flow, air and foam liquid are completely mixed. By providing a foaming claw 80 at the foaming outlet 102, the foam can be completely broken up, so that the sprayed foam becomes uniform.

[0039] The present application also provides a smart toilet, such as Figure 6 and Figure 7As shown, the smart toilet 901 includes: a nut (not shown), which is threadedly connected to the side wall of the foaming nozzle 902 to clamp the foaming nozzle 902 on the side wall of the smart toilet 901. The foaming nozzle 902 is any one of the foaming nozzles 902 described above.

[0040] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application.
