Description

A spray bar assembly that generates particulate water, a cleaning device, and a smart toilet. Technical Field

[0001] This utility model relates to the field of sanitary ware, and in particular to a spray bar assembly that can generate particulate water, a cleaning device, and a smart toilet. Background Technology

[0002] With the continuous development of technology and the increasing demands of consumers, the application functions of smart toilets are also constantly innovating. Common cleaning functions of smart toilets include posterior washing and feminine wash, which are achieved through the structure of the smart toilet spray nozzle assembly. Currently, most smart toilet spray nozzle assemblies on the market offer only a single water jet for feminine wash, typically using one or multiple jets simultaneously. This can result in a small washing area and a less than ideal feel, especially for women with sensitive areas or sensitive skin, as the concentrated water jet force of traditional single or multiple jets can create a negative experience.

[0003] Utility Model Content

[0004] This invention aims to solve the problems of small rinsing area and poor user experience caused by the water spray from the spray bar assembly. Therefore, it provides a spray bar assembly that can generate particulate water, as well as a cleaning device and smart toilet including the spray head assembly, which is equipped with a thin sheet to scatter water spray, and cleans with a gentle water pattern, providing a more comfortable user experience.

[0005] To solve the above-mentioned technical problems, the present invention provides a spray bar assembly that can generate particulate water. The spray bar assembly includes a nozzle assembly, which includes a housing, a lower water outlet housing, an upper water outlet housing, and a diverter.

[0006] The diverter is provided with two inlet channels, two large-section cavities, and one guide cavity; each of the two inlet channels is connected to the inlet side of the two large-section cavities; the outlet side of the two large-section cavities is connected to different positions on the side of the guide cavity; the cross-sectional area of ​​the guide cavity is smaller than that of the large-section cavities.

[0007] The upper shell of the water outlet is provided with an opening that connects to the guide cavity. After the water flows through the two large-section cavities, it enters the guide cavity in different directions and collides with it to form granular water droplets that are ejected from the opening.

[0008] In a preferred embodiment: the guide cavity and the opening are connected by a strip-shaped hole, and the opening and the strip-shaped hole are combined to form a racetrack-shaped water outlet.

[0009] In a preferred embodiment: the opening is circular, and the diameter of the opening is greater than the width of the strip hole and less than the length of the strip hole.

[0010] In a preferred embodiment: the two large-section cavities are symmetrically arranged relative to the guide cavity.

[0011] In a preferred embodiment: the opening is coaxially arranged with the guide cavity.

[0012] In a preferred embodiment: the water spray from the outlet is a thin, fan-shaped, scattering particle water spray.

[0013] In a preferred embodiment, the water flow rates of the two water inlet channels are the same.

[0014] In a preferred embodiment: an installation cavity is provided inside the water outlet upper shell, and the diverter is placed inside the installation cavity; the upper part of the installation cavity, the large cross-section cavity, and the guide cavity form a communicating cavity.

[0015] This utility model also provides a cleaning device, including the aforementioned spray bar assembly.

[0016] This utility model also provides a smart toilet, which is equipped with the cleaning device as described in claim 9.

[0017] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0018] 1. By setting up a guide cavity, in conjunction with the large cross-section cavities on both sides, the water flow is diverted into the guide cavity in two directions, and the two water flows collide with each other in the guide cavity, causing the water flow to be broken into small particles, thus forming granular water splashes.

[0019] 2. Through the cooperation of the guide cavity and the opening, the water flow undergoes a shape-adaptive process in the racetrack-shaped outlet, and under the guidance of the outlet, the ejected water flow is similar to a thin sheet fan-shaped scattering pattern.

[0020] 3. A nozzle assembly capable of producing thin, fan-shaped, scattering water droplets is provided, unlike ordinary single or multi-column direct-jet feminine washes. It offers a wider coverage area and more abundant water droplets per unit volume, making feminine washing more comfortable. This solves the problem of traditional single or multi-column water jets, which, with their concentrated impact, can cause unpleasant experiences for women with sensitive areas or skin.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0035] Referring to Figures 1-10, this embodiment provides a spray bar assembly 2 that can generate particulate water. The spray bar assembly 2 includes a nozzle assembly 1. The spray bar assembly 2 is a spray bar assembly 2 for a smart toilet and is mainly used for the water outlet device of the cleaning device 3 (as shown in Figure 10).

[0036] As shown in Figure 1, the nozzle assembly 1 includes a housing 11, an upper water outlet housing 13, a diverter 14, and a lower water outlet housing 12. The upper water outlet housing 13 has an installation cavity 132 (as shown in Figure 3). The diverter 14 is placed in the installation cavity 132, and a waterproof sealing ring 16 is installed between the installation cavity 132 and the diverter 14.

[0037] As shown in Figure 4, the diverter 14 is provided with two water inlet channels 141, two large-section cavities 142, and one guide cavity 143. The guide cavity 143 is a small-section cavity, and the cross-sectional area of ​​the small-section cavity is smaller than that of the large-section cavity 142. One water inlet channel 141 is connected to one large-section cavity 142. In the upper part of the mounting cavity 132, the large-section cavity 142 and the guide cavity 143 form a connected cavity. In this connected cavity, the guide cavity 143 is symmetrically arranged in the middle, and the two large-section cavities 142 are symmetrically arranged on both sides of the guide cavity 143 (as shown in Figure 7).

[0038] As shown in Figure 5, a water distribution chamber 121 is provided on the lower housing 12 of the water outlet. The water flow enters the distributor 14 through the water distribution chamber 121 and is divided into two water flows by the two water inlet channels 141 of the distributor 14. The water flow rates of the two water inlet channels 141 are the same.

[0039] An opening 131 is provided on the upper shell 13, and the opening 131 is located at the center of the guide cavity 143. The cross-sectional area of ​​the opening 131 is larger than the cross-sectional area of ​​the guide cavity 143. The guide cavity 143 and the opening 131 are combined, and the projection shape of their contact surface is set as a racetrack shape. This racetrack-shaped structure is set to resemble a long racetrack, but is not limited to a long racetrack shape, and can be a racetrack shape similar to a rectangle. In this embodiment, a long racetrack shape is used as an example.

[0040] In this embodiment, the guide cavity 143 is shaped as a long strip, rectangle, U-shape, semi-circle, or semi-circular arc. The opening 131 is circular or rectangular, and the length of the opening 131 along the guiding direction of the guide cavity 143 is less than the length of the guiding segment of the guide cavity 143. In this embodiment, the opening 131 is circular, and the connection between the guide cavity 143 and the opening 131 is a long strip hole. Furthermore, the diameter of the opening 131 is greater than the width of the strip hole but less than the length of the strip hole. This allows the water outlet 15 to be formed at the junction of the opening 131 and the strip hole. A decorative hole 111 is provided on the outer casing 11 corresponding to the opening 131, through which water spray from the opening 131 is ejected, as shown in Figure 2.

[0041] In this embodiment, the generation principle of the thin-film fan-shaped scattering particle water spray 4 is as follows: After the water flows into the water distribution chamber 121, it can enter through the two water inlet channels 141 of the diverter 14. The two water inlet channels 141 divide the water flow into two water streams with equal flow rates. The two water streams flow into the corresponding large-section cavities 142 through the two water inlet channels 141 respectively. The two water streams then flow from the side of the large-section cavity 142 to the small-section guide cavity 143 respectively, and then are released through the opening 131. During this process, the water pressure increases and then decreases. As the two water streams collide in the small-section guide cavity 143, the water streams are broken into small particles, forming particle water spray. Since the guide cavity 143 and the opening 131 combine to form a structure similar to a long strip-shaped racetrack-shaped opening 15, the water flow undergoes a shape-adaptive process. Under the guidance of the opening 131 of the water outlet upper shell 13, the ejected water flow is in the form of a thin-film fan-shaped scattering pattern, as shown in Figure 8.

[0042] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model. Industrial applicability

[0043] This invention provides a spray bar assembly that generates particulate water, unlike ordinary single or multi-column direct-jet feminine washes. It offers a wider coverage area and produces more water droplets per unit volume, resulting in a more comfortable feminine wash experience. It solves the problem of traditional single or multi-column water sprays, which, with their concentrated impact, can cause discomfort to sensitive areas or skin types, and thus has good industrial applicability.
