Description

Technical Field

[0001] This utility model belongs to the field of intelligent toilet technology, and specifically relates to a feminine wash nozzle assembly and an intelligent toilet. Background Technology

[0002] Existing water spraying devices generally include a nozzle, a handle, and a spray body. The nozzle has a water inlet passage and a vortex chamber, and the spray body is rotatably mounted on the handle and installed in the vortex chamber in this held state. When cleaning water flows into the vortex chamber from the water inlet passage, the cleaning water swirls around the force-bearing part of the spray body along the inner wall of the vortex chamber, and acts as lift on the spray body in the aforementioned manner, causing the spray body to rotate in a wobbling motion, thereby widening the spray range.

[0003] However, in this technical solution, the effect of the water jet body in widening the spray range depends on the rotation of the water jet body on the handle. During long-term use, wear is likely to occur between the water jet body and the handle, which will cause the gap between the two to widen, thereby affecting the uniformity of the rotation of the water jet body on the handle, resulting in uneven spray range of the water jet body.

[0004] Therefore, this application provides a bidet spray nozzle assembly and a smart toilet, which changes the way the water spray body in the nozzle expands the spray range and ensures the uniformity of the spray range. Utility Model Content

[0005] This utility model provides a feminine wash nozzle assembly and a smart toilet, aiming to solve the problems pointed out in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A feminine wash nozzle assembly includes: a nozzle body and a water spray body;

[0008] The upper part of the nozzle body is provided with an installation cavity for installing the water spray body, and the inside of the nozzle body is provided with a water pipe, a connecting pipe and a water storage chamber connected in sequence.

[0009] The lower part of the water spray body is an extension pipe, and the upper end of the extension pipe is provided with a clamping connector. The circumferential sidewall of the extension pipe is provided with several water inlets, and the inner cavity is provided with a guide cavity communicating with the water inlets. The inner cavity of the clamping connector is provided with a conical spiral water channel communicating with the guide cavity, and the upper end of the clamping connector is provided with a water outlet communicating with the conical spiral water channel.

[0010] The extension tube is disposed in the water storage chamber, and the snap-fit ​​connector mates with the mounting cavity.

[0011] Furthermore, a sealing groove is provided on the outer circumferential side wall of the snap-fit ​​connector, and a sealing ring is nested in the sealing groove. The sealing ring cooperates with the side wall of the mounting cavity to form a sealed connection between the snap-fit ​​connector and the mounting cavity.

[0012] Furthermore, a pressure cap is snapped onto the upper part of the nozzle body. The pressure cap cooperates with the nozzle body to fix the water spray body. An avoidance hole is provided on the pressure cap, and the avoidance hole cooperates with the water outlet.

[0013] Furthermore, the lower part of the mounting cavity is provided with a first mating surface, and the lower surface of the pressure cap is provided with a second mating surface. The first mating surface is an arc surface that abuts against the lower edge of the snap-fit ​​connector, and the second mating surface is in clearance fit with the upper edge of the snap-fit ​​connector, so that the water spray body can swing when impacted by water flow, thereby expanding the rinsing area.

[0014] Furthermore, the diameter of the flow guiding cavity is larger than the diameter of the water outlet.

[0015] Furthermore, the cross-sectional area of ​​the conical spiral waterway gradually decreases from bottom to top.

[0016] Furthermore, a mating head is provided on one side of the nozzle body, which is used to mate with an external water supply component.

[0017] Furthermore, the sealing ring is made of either a hard or soft material to control the overall oscillation range of the water spray body.

[0018] Furthermore, this application also provides a smart toilet, including: a main unit and a seat ring. The main unit is provided with a water supply pipe. One end of the water supply pipe is connected to a water supply component, and the other end is connected to the inlet end of a water inlet valve. The outlet end of the water inlet valve is connected to one end of a spray rod. The other end of the spray rod is provided with a feminine wash nozzle assembly as described above. The middle part of the seat ring is a seat ring inner hole, and the position of the seat ring inner hole corresponds to that of the feminine wash nozzle assembly.

[0019] Compared with the prior art, the present invention has the following technical effects:

[0020] 1. The feminine wash nozzle assembly of this utility model features a conical spiral water channel connected to a guide cavity within the inner cavity of the connector in the spray body. When water enters the conical spiral water channel from the guide cavity, the water flows along the spiral path. This spiral flow causes the water to rotate, increasing its kinetic energy and pressure, ultimately forming a water flow with a certain rotational and dispersive effect when sprayed from the outlet. This rotating and dispersed water flow not only expands the washing area and improves washing efficiency but also makes washing gentler and more uniform, reducing irritation to the body and enhancing the user experience. Furthermore, the spray body is fixed as a whole, reducing wear on mating components, thereby increasing its service life and reducing the probability of failure. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments of this application and the accompanying drawings.

[0032] like Figure 1-3 As shown, a feminine wash nozzle assembly includes: a nozzle body 1 and a water spray body 2;

[0033] The upper part of the nozzle body 1 is provided with an installation cavity 101 for installing the water spray body 2, and the interior of the nozzle body 1 is provided with a water pipe 104, a connecting pipe 105 and a water storage chamber 103 connected in sequence.

[0034] The lower part of the water spray body 2 is an extension pipe 201, and the upper end of the extension pipe 201 is provided with a clamping connector 202. The circumferential sidewall of the extension pipe 201 is provided with several water inlets 203, and the inner cavity is provided with a guide cavity 204 communicating with the water inlets 203. The inner cavity of the clamping connector 202 is provided with a conical spiral water channel 205 communicating with the guide cavity 204, and the upper end of the clamping connector 202 is provided with a water outlet 206 communicating with the conical spiral water channel 205.

[0035] The extension tube 201 is disposed in the water storage chamber 103, and the snap connector 202 is engaged with the mounting cavity 101.

[0036] A conical spiral water channel 205, connected to the guide cavity 204, is set within the inner cavity of the connector 202 of the water spray body 2. When water enters the conical spiral water channel 205 from the guide cavity 205, the water flow follows a spiral path. This spiral flow causes the water to rotate, increasing its kinetic energy and pressure. Ultimately, when sprayed out from the outlet 203, it forms a water flow with a certain rotational and dispersive effect. This rotating and dispersed water flow not only expands the cleaning area and improves cleaning efficiency but also makes cleaning gentler and more uniform, reducing irritation to the human body and enhancing the user experience. Furthermore, the water spray body 2 is fixed in place, reducing wear on mating components, thereby increasing its service life and reducing the probability of failure.

[0037] In one specific embodiment, by changing the spiral angle, pitch, and other parameters of the conical spiral waterway 205, the degree of rotation and dispersion of the water flow can be adjusted, thereby achieving different water spraying modes to meet the personalized needs of different users.

[0038] like Figure 1-2 As shown, a sealing groove 207 is provided on the outer circumferential side wall of the snap-fit ​​connector 202, and a sealing ring 208 is nested in the sealing groove 207. The sealing ring 208 cooperates with the side wall of the mounting cavity 101 to form a sealed connection between the snap-fit ​​connector 202 and the mounting cavity 101.

[0039] When a good seal is achieved between the connector 202 and the mounting cavity 101, the water flow can flow along a predetermined path inside the nozzle, avoiding pressure loss due to leakage. This ensures stable water pressure of the spray body 2, giving the sprayed water sufficient strength and range, thereby improving the cleaning effect.

[0040] like Figure 4 As shown, a pressure cap 3 is snapped onto the upper part of the nozzle body 1. The pressure cap 3 cooperates with the nozzle body 1 to fix the water spray body 2. The pressure cap 3 has an clearance hole 301, which cooperates with the water outlet 206. The pressure cap 3 is installed by snapping, which is relatively simple to operate. During installation, users or maintenance personnel only need to accurately snap the pressure cap 3 onto the nozzle body 1 to fix the water spray body 2. When it is necessary to clean, replace or repair the water spray body 2, the pressure cap 3 can also be easily removed from the nozzle body 1 without the need for complicated tools and operating procedures.

[0041] like Figure 3-4 As shown, the lower part of the mounting cavity 101 is provided with a first mating surface 102, and the lower surface of the pressure cap 3 is provided with a second mating surface 302. The first mating surface 102 is an arc surface that abuts against the lower edge of the snap-fit ​​connector 202. The second mating surface 302 is in clearance fit with the upper edge of the snap-fit ​​connector 202, which facilitates the swaying of the water spray body 2 when impacted by water flow, thereby expanding the rinsing area and producing an intermittent rinsing sensation, improving the user experience. The two mating surfaces provide a precise positioning reference for the installation of the water spray body 2. When installing the water spray body 2, the user only needs to align the upper and lower edges of the snap-fit ​​connector 202 with the first mating surface 102 and the second mating surface 302, respectively, to accurately install the water spray body 2 in the appropriate position, ensuring that the water outlet 206 of the water spray body 2 is precisely aligned with the clearance hole 301 on the pressure cap, avoiding problems such as abnormal water spraying caused by inaccurate installation position.

[0042] like Figure 2 As shown, the diameter of the guide cavity 204 is larger than the diameter of the outlet 206. When water flows from the larger diameter guide cavity 204 into the smaller diameter outlet 206, the cross-sectional area decreases. With the flow rate remaining relatively stable, the water velocity increases, which increases the water pressure at the outlet, thus giving the ejected water a stronger impact force and a longer range.

[0043] like Figure 2As shown, the cross-sectional area of ​​the conical spiral water channel 205 gradually decreases from bottom to top. The spiral shape of the water channel itself guides the water flow, enabling the water to form a spiral flow trajectory within the channel. The gradually decreasing cross-sectional area further enhances this spiral flow effect. During the upward flow of the water, the spiral motion makes the water flow more evenly distributed in the circumferential direction, avoiding water flow concentration on one side or localized excessively strong or weak water flow. When the water finally sprays out from the outlet, it forms a relatively uniform water curtain with appropriate coverage, more comprehensively covering the areas that need cleaning.

[0044] like Figure 3 As shown, a mating head 106 is provided on one side of the nozzle body 1, and the mating head 106 is used to mate with an external water supply component.

[0045] In one specific embodiment, the sealing ring 208 is either a hard or soft sealing ring to control the overall swing range of the water spray body 2. Since the water spray body 2 is in clearance fit with the nozzle body 1 and the pressure cap 3 in the vertical direction, the extension tube 201 at the bottom will also cause the water spray body 2 to swing to a certain extent under the impact of water flow, further expanding the cleaning area. The swing range of the water spray body 2 can be appropriately controlled by the hardness of the sealing ring 208. For example, a soft sealing ring 208 can be used when a larger swing range is required, while a hard sealing ring 208 can be used when a smaller swing range needs to be controlled, for example, rubber sealing rings of different hardness.

[0046] like Figure 5 As shown, this application also provides a smart toilet, including: a main unit 7 and a seat ring 8. The main unit 7 is provided with a water supply pipe 6. One end of the water supply pipe 6 is connected to a water supply component, and the other end is connected to the water inlet end of a water inlet valve 5. The water outlet end of the water inlet valve 5 is connected to one end of a spray rod 4. The other end of the spray rod 4 is provided with a feminine wash nozzle assembly as described above. The middle part of the seat ring 8 is a seat ring inner hole 9, and the seat ring inner hole 9 corresponds to the position of the feminine wash nozzle assembly.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
