Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to a foaming flushing nozzle and toilet. Background Technology

[0002] Currently, smart toilets with foam shield functions typically use a foaming device to generate a foam layer, which is then applied to the water surface of the toilet bowl to achieve splash prevention, odor isolation, wall lubrication, and sterilization. However, in existing foam shields, the foam is usually emitted from the front of the lid and falls directly onto the ceramic water surface to form a foam layer. This direct-falling foam only covers a small area of ​​the water surface, leaving other areas of the ceramic bowl uncovered, thus limiting the effectiveness of wall lubrication, sterilization, and cleaning.

[0003] Specifically, existing technologies use rotating foam nozzles to spray foam to cover the ceramic surface. However, this method requires additional components such as air pumps and rotary motors, increasing complexity, failure rate, and cost. Existing technologies also utilize flushing nozzles to spray foam, allowing it to circulate and cover the entire ceramic surface with the flushing water flow. While this significantly reduces cost, its application has limitations.

[0004] Specifically, most methods of generating foam using a flushing nozzle employ the Venturi principle for aspiration and foaming. This requires a high flow rate, but the flow volume cannot be too large. If the flow rate is too low, the foaming effect will be affected; if the flow rate is too high, it can create a siphon effect, washing away the foam. However, regardless of the water flow, the flushing process still relies on the bottom flush, necessitating the use of a switching valve to switch between top flush and bottom flushing modes. This not only increases costs but also generates significant noise. For silent toilets without a bottom flush, which only have a top flush nozzle and require a large flow of water to create a siphon effect to remove waste, the aforementioned method of generating foam cannot be used.

[0005] Therefore, how to achieve the effect of foaming and moisturizing the brush ring when flushing the toilet with water of varying flow rates is a problem that needs to be solved by people in this field. Utility Model Content

[0006] The purpose of this invention is to provide a foaming flushing nozzle and toilet, so that when the water flow is large or small, the flushing effect is not affected, and the brush ring can be foamed and moistened.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] Foaming spray nozzle, including:

[0009] The nozzle body comprises a flow control component and a foaming structure. The flow control component is movably disposed within the nozzle body, and the foaming structure is connected to the nozzle body. The foaming rinsing nozzle includes at least a first state and a second state. In the first state, water flows sequentially through the flow control component and the foaming structure to generate foam before being sprayed out. In the second state, the flow control component moves toward the foaming structure, and the water flow does not generate foam before being sprayed out.

[0010] Optionally, it also includes a water inlet connected to the side of the nozzle body away from the foaming structure. In the first state, the flow control component abuts against the water inlet, and in the second state, there is a pressure relief gap between the flow control component and the water inlet.

[0011] Optionally, the nozzle body is provided with an annular water channel, and the annular water channel is opened on one side facing the foaming structure. In the first state, the annular water channel is closed, and in the second state, the pressure relief gap is connected to the annular water channel.

[0012] Optionally, the nozzle body is provided with a limiting boss, and the flow control component is movably disposed at the limiting boss. In the second state, the flow control component is limited to the end face of the limiting boss.

[0013] Optionally, the flow control assembly includes a flow control plug and an elastic member, one end of which is connected to the flow control plug and the other end of which is connected to the limiting boss.

[0014] Optionally, the nozzle body is provided with a foaming channel, and the flow control component and the foaming structure are both connected to the foaming channel.

[0015] Alternatively, the inner diameter of the flow control component may be smaller than the inner diameter of the foaming channel.

[0016] Optionally, the nozzle body is provided with an air intake section that is connected to the foaming channel.

[0017] Optionally, the nozzle body is provided with a liquid injection section that is connected to the foaming channel.

[0018] On the other hand, a toilet, including a foaming flush nozzle, into which water can flow.

[0019] The beneficial effects of this utility model are:

[0020] This invention utilizes a flow control component to switch between different states of the foaming flushing nozzle, thereby achieving the effects of foaming the brush ring and moistening the toilet bowl, as well as flushing. Specifically, the foaming flushing nozzle has a foaming structure to facilitate foaming, and it has at least a first state and a second state. In the first state, the water flow produces foam before spraying, while in the second state, the water flow does not produce foam. The position of the flow control component can be controlled according to the different states of the water flow, thus achieving different states of the foaming flushing nozzle. This ensures that the flushing effect is maintained while achieving the effect of foaming the brush ring and moistening the toilet bowl when the water flow is adjusted at different rates. This not only avoids the use of too many parts, reducing the equipment failure rate, but also reduces costs and eliminates limitations in its use. Furthermore, a toilet equipped with a foaming flushing nozzle also achieves the aforementioned flushing and brush ring foaming effects. Attached Figure Description

For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0042] like Figures 1-8 As shown, in this embodiment, the foaming rinsing nozzle 100 includes a nozzle body 10, a water inlet 20, a flow control component 30, and a foaming structure 40. Optionally, the water inlet 20 and the foaming structure 40 are respectively disposed on both sides of the nozzle body 10, and are connected to the nozzle body 10 by snap-fit ​​or ultrasonic welding to ensure structural stability. Other connection methods can also be selected in other embodiments, and no limitation is made here. Further, the flow control component 30 is movably disposed inside the nozzle body 10 to switch different working states of the foaming rinsing nozzle 100.

[0043] For example, in this embodiment, the foaming flushing nozzle 100 has at least a first state and a second state. In the first state, water flows in through the inlet 20, passes through the flow control component 30 and the foaming structure 40 in sequence to generate foam, and then sprays out, achieving the effect of foaming the toilet brush ring so that the foam can cover the entire ceramic surface. Further, in the second state, the flow control component 30 moves towards the foaming structure 40 within the nozzle body 10, and after the water flows in through the inlet 20, no foam is generated and sprayed out, achieving the toilet flushing effect. Optionally, in this embodiment, the first state is a low-flow state, where the water flow cannot push the flow control component 30 to move, and foaming operation is performed at this time; the second state is a high-flow state, where the water flow can push the flow control component 30 to move, thereby achieving a high-flow flushing effect for the toilet. Correspondingly, when the water flow rate is between the first state and the second state, the flow control component 30 moves a smaller distance, and whether foaming operation is performed at this time can be set as needed. Therefore, the brush ring is foamed at low flow rates and used for toilet flushing at high flow rates, which saves water while achieving the purpose of preventing splashing, odor isolation, wall lubrication, and sterilization after the toilet is foamed. In other embodiments, different flow rates can be set according to actual needs, which will not be elaborated here.

[0044] like Figure 7As shown, the length direction of the nozzle body 10 is set as the first direction, and the radial direction of the nozzle body 10 is set as the second direction. Specifically, a foaming channel 101 is provided inside the nozzle body 10 along the first direction. The flow control component 30 and the foaming structure 40 are both connected to the foaming channel 101, and the inner diameter of the flow control component 30 is smaller than the inner diameter of the foaming channel 101 to facilitate subsequent foaming operations. Correspondingly, an annular water channel 102 and a receiving cavity 103 are also provided inside the nozzle body 10. The annular water channel 102 is arranged around the outside of the foaming channel 101, and the annular water channel 102 is opened on the side facing the foaming structure 40 to facilitate water flow. Further, the receiving cavity 103 is connected to the annular water channel 102, and the receiving cavity 103 is located on the other side of the foaming channel 101 connecting to the foaming structure 40.

[0045] Specifically, a limiting boss 11 extends within the receiving cavity 103 along the first direction inside the nozzle body 10, and a hollow inner cavity 111 is provided within the limiting boss 11. The hollow inner cavity 111 extends through the first direction and connects to the foaming channel 101. Specifically, the inner diameter of the hollow inner cavity 111 is smaller than the inner diameter of the foaming channel 101 to ensure accelerated flow of subsequent water. For example, the flow control component 30 is movably disposed at the limiting boss 11, and in the second state, the flow control component 30 moves towards the foaming structure 40 under the push of the water flow and is confined at the end face of the limiting boss 11. This provides support, guidance, and limitation of the movement range for the flow control component 30 through the limiting boss 11. Figure 10 As shown, by way of example, the end face of the limiting boss 11 is provided with a limiting step 112, which can limit the movement of the flow control component 30.

[0046] Optionally, the nozzle body 10 is further provided with an air intake section 12, which is connected to the foaming channel 101. When a negative pressure is generated in the foaming channel 101, air can be drawn into the foaming channel 101 through the air intake section 12, which is beneficial for foaming. For example, the air intake section 12 is provided with an air intake port 121, and an air intake channel 104 is provided through the air intake section 12 along a second direction. Optionally, both ends of the air intake channel 104 are connected to the air intake port 121 and the foaming channel 101, respectively. Air is drawn into the air intake channel 104 through the air intake port 121 and then enters the foaming channel 101 to participate in foaming.

[0047] Optionally, the nozzle body 10 is further provided with an injection section 13, which is connected to the foaming channel 101 to input a mixed liquid containing a foaming agent into the foaming channel 101, thereby promoting the generation of water foam. Exemplarily, the injection section 13 is provided with an injection port 131, and an injection channel 105 is provided through the injection section 13 along a second direction. Optionally, both ends of the injection channel 105 are connected to the injection port 131 and the foaming channel 101, respectively, so that the mixed liquid containing the foaming agent enters the injection channel 105 through the injection port 131 and can then enter the foaming channel 101 to participate in foaming.

[0048] For example, the air intake 12 and the liquid injection 13 are located on opposite sides of the nozzle body 10, with the air intake 12 positioned above and the liquid injection 13 positioned below, thereby ensuring separate input of air and mixed liquid. Specifically, the position, angle, and shape of the air intake channel 104 and the liquid injection channel 105 can be set as needed and are not limited here.

[0049] like Figure 7 As shown, in this embodiment, one of the water inlet component 20 and the nozzle body 10 is provided with a limiting protrusion, and the other is provided with a limiting groove. The limiting protrusion and the limiting groove are engaged with each other to ensure a stable connection between the water inlet component 20 and the nozzle body 10. Specifically, the water inlet component 20 is located on the side of the nozzle body 10 away from the foaming structure 40, and a water inlet channel 201 is provided inside the water inlet component 20. In the first state, the water inlet channel 201 is connected to the flow control component 30, and in the second state, the water inlet channel 201 is connected to the receiving cavity 103, thereby achieving a stable water flow input and allowing the water flow to be sprayed in different ways at different flow rates. Further, a limiting ring 202 is provided inside the water inlet channel 201 near the flow control component 30 to restrict the movement of the flow control component 30 along the first direction.

[0050] Combination Figure 7 and Figure 8 As shown, optionally, the flow control assembly 30 includes a flow control plug 31 and an elastic member 32, with one end of the elastic member 32 connected to the flow control plug 31 and the other end connected to the limiting boss 11, thereby ensuring the stable installation of the flow control assembly 30 within the nozzle body 10 and allowing the flow control plug 31 to move within the nozzle body 10. Specifically, the flow control plug 31 is provided with a through channel 301, and both ends of the through channel 301 are respectively connected to the foaming channel 101 and the water inlet channel 201 to ensure stable water flow. Further, the inner diameter of the through channel 301 is smaller than that of the foaming channel 101 and the water inlet channel 201. As a result, when water flows through the water inlet channel 201 into the through channel 301 and then into the foaming channel 101, a Venturi effect is generated, thereby creating a negative pressure within the foaming channel 101 so that air can be smoothly drawn in for foaming operations.

[0051] Furthermore, in this embodiment, the flow control plug 31 includes an abutment portion 311 and a main body portion 312, wherein the main body portion 312 is movably disposed in the hollow inner cavity 111 within the limiting boss 11, and the abutment portion 311 is connected to the main body portion 312 and can abut against the limiting step 112 of the limiting boss 11 or the limiting ring 202 of the water inlet member 20. Specifically, the elastic member 32 is sleeved on the limiting boss 11 and connected to the abutment portion 311, thereby enabling the abutment portion 311 to be subjected to an outward force in a first direction when the water flow rate is small in the first state, and the abutment portion 311 to compress the elastic member 32 when the water flow rate is large in the second state.

[0052] Optionally, the inner diameter of the limiting ring 202 is smaller than the outer diameter of the abutment portion 311, and the outer diameter of the abutment portion 311 is larger than the outer diameter of the limiting step 112, thereby limiting the movement range of the flow control plug 31 along the first direction under the action of the limiting ring 202 and the limiting step 112. For example, in the second state, there is a gap between the abutment portion 311 and the limiting ring 202; in this embodiment, this gap is set as a pressure relief gap 302. Specifically, the pressure relief gap 302 is connected to the receiving cavity 103, thereby connecting to the annular cavity water channel 102, allowing water to enter the receiving cavity 103 through the pressure relief gap 302 and then be ejected from the opening side of the annular cavity water channel 102, improving the flushing effect.

[0053] like Figure 9 As shown, in the first state, the water flow rate is relatively small and the impact force is less than the elastic force of the elastic element 32. The abutment part 311 abuts against the limiting ring 202 to isolate the accommodating cavity 103 from the water inlet channel 201, sealing the annular water channel 102 and the accommodating cavity 103. At this time, the water flows sequentially through the water inlet channel 201, the through channel 301, and the hollow inner cavity 111 into the foaming channel 101. Specifically, the inner diameters of the through channel 301 and the hollow inner cavity 111 are both smaller than those of the foaming channel 101 and the water inlet channel 201, which generates a Venturi effect, causing negative pressure to be generated in the foaming channel 101. Air is then drawn into the foaming channel 101 through the air intake channel 104. Meanwhile, to ensure the foaming effect, a mixed liquid containing a foaming agent is sprayed into the foaming channel 101 through the injection channel 105, so that it merges with the water flow and air in the foaming channel 101, further enhancing the Venturi effect to increase the air intake. Then, the merged liquid impacts the foaming structure 40 as a whole, which generates foam and completes the brush ring foaming.

[0054] like Figure 10As shown, in the second state, the water flow rate is larger and the impact force is greater than the elastic force of the elastic element 32. The abutment part 311 squeezes the elastic element 32 until it abuts against the limiting step 112. At this time, a pressure relief gap 302 is generated. Under the connecting effect of the pressure relief gap 302, the receiving cavity 103 is connected to the water inlet channel 201, thereby realizing the connection between the annular water channel 102 and the water inlet channel 201. At this time, the water flow is sprayed out through two water paths. Specifically, one is the water path that sprays out from the opening side of the annular water channel 102 after passing through the water inlet channel 201, the pressure relief gap 302, and the receiving cavity 103. The other is the water path that enters the foaming channel 101 through the water inlet channel 201 and the through channel 301, and then sprays out from the foaming structure 40. Exemplarily, the two water paths can converge on the same side of the nozzle body 10 and spray out the brush ring together to achieve toilet cleaning and meet the flushing requirements of a large flow of water.

[0055] Optionally, in this embodiment, the foaming structure 40 includes several mesh structures with toothed openings and a foaming port 401 to enhance the foaming effect of the impacting water flow, thereby improving the foaming effect and allowing the foamed water to be sprayed out through the foaming port 401. Exemplarily, the foaming structure 40 is configured as a tower-like structure; in other embodiments, it can also be configured as a mesh or other forms to better control the foaming flow rate and meet usage requirements. Further, by adjusting the elasticity of the elastic element 32 and the inner diameter of the through-channel 301 within the flow control component 30, the water flow rate and foaming effect can be controlled accordingly, and can be specifically set as needed. Exemplarily, in other embodiments, the flow control plug 31 can also be configured as an elastic structure such as rubber, thereby cooperating with the impact force of the water flow to achieve different foaming and rinsing effects. In this case, the use of the elastic element 32 can be eliminated, further simplifying the structure. Exemplarily, whether foaming and rinsing are performed in this embodiment depends on whether a mixed liquid containing a foaming agent is input into the injection unit 13; therefore, the input time and content of the mixed liquid can be adjusted according to actual needs, and no restrictions are imposed here.

[0056] The structure of the toilet in this embodiment will be described in detail below.

[0057] Combination Figures 1-3As shown, in this embodiment, the toilet includes the aforementioned foaming flushing nozzle 100, flushing pump 200, power unit 300, and connecting pipe 400. Optionally, after the flushing pump 200 is started, water can enter the foaming flushing nozzle 100 to achieve water input. Further, the power unit 300 is connected to the injection section 13 of the foaming flushing nozzle 100 and the connecting pipe 400, and the connecting pipe 400 is used to connect a mixed liquid containing a foaming agent. Thus, by controlling the power unit 300, the mixed liquid can be delivered to the foaming flushing nozzle 100 for foaming. Exemplarily, the toilet equipped with the foaming flushing nozzle 100 can perform foaming flushing at a low flow rate and toilet flushing at a high flow rate, saving water while achieving a combined flushing and foaming effect, thus improving the cleaning effect of the toilet.

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.
