Detailed Implementation

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] This utility model relates to a flushing nozzle, including a venturi channel 100, a vibration zone 200 and a first water outlet channel 300.

[0028] like Figure 1 and Figure 2As shown, the Venturi channel 100, the vibration zone 200, and the first water outlet channel 300 are sequentially connected. When water flows along the Venturi channel 100, a Venturi effect is generated, creating a negative pressure zone 101 within the Venturi channel 100. The Venturi channel 100 has an air intake channel 110 at a position corresponding to the negative pressure zone 101. The negative pressure zone 101 is directly connected to the external environment through the air intake channel 110, drawing air from the external environment into the Venturi channel 100. The vibration zone 200 has a first opening 220, through which it connects to the first water outlet channel 300. The vibration zone 200 has multiple blocking sections 210. These blocking sections 210 are distributed sequentially and at intervals around the first opening 220. The blocking sections 210 are located on the water flow path from the Venturi channel 100 to the first water outlet channel 300. Alternatively, the direction in which the fluid enters from the Venturi channel 100 into the vibration zone 200 can be defined as the first direction, and the direction in which the fluid exits from the first outlet 220 into the first outlet channel 300 through the vibration zone 200 can be defined as the second direction. The first and second directions are not parallel to each other; the first direction can be perpendicular to the second direction, or the first and second directions can form an acute or obtuse angle.

[0029] In use, the upstream end of the Venturi channel 100 is connected to an external water supply system, such as a water tank or tap water pipe. Water flows sequentially along the Venturi channel 100, the vibration zone 200, and the first outlet channel 300, finally being ejected outward from the first outlet channel 300. Initially, as water flows through the Venturi channel 100, a negative pressure is created in the negative pressure zone 101. External air is drawn into the negative pressure zone 101 through the intake channel 110, where water and air mix. Some of the water vapor in the vibration zone 200 is ejected outward through the first opening 220 into the first outlet channel 300, while some water impacts the blocking part 210 and, due to the rebound effect of the blocking part 210, flows back towards the Venturi channel 100, affecting the airflow. The airflow, disturbed by the obstruction part 210 and the water flow, causes some water vapor to flow back to the vicinity of the air intake channel 110, increasing the air pressure in the area near the air intake channel 110, reducing the original negative pressure, and decreasing the intake volume until no air is drawn in. As the internal water and airflow gradually decrease through the first water outlet channel 300, the pressure near the air intake channel 110 gradually decreases again, and air begins to be drawn in from the outside again. This cycle repeats, creating a pulse water output effect. The overall structure of the flushing nozzle is simple, requiring no air pump or other electrical components to achieve pulse water output, resulting in low structural cost. This utility model also relates to a spray gun that utilizes the aforementioned flushing nozzle. The flushing nozzle achieves the pulse water output function of the spray gun. This utility model also relates to a toilet that utilizes the aforementioned flushing nozzle or spray gun. When using the toilet, the user uses the flushing nozzle or spray gun for pulse-jet washing of the buttocks or feminine genitals, enhancing the cleaning function.

[0030] In one embodiment, such as Figure 2 As shown, the blocking portion 210 can be configured to extend in a strip shape along the second direction. The two opposite sidewalls of the vibration zone 200 in the second direction are a first wall 230 and a second wall 240, respectively. The two ends of the blocking portion 210 are connected to or abut against the first wall 230 and the second wall 240, respectively. A first opening 220 is formed on either the first wall 230 or the second wall 240. Each blocking portion 210 is sequentially distributed around the first opening 220; after water vapor enters the vibration zone 200, some of the water vapor will inevitably impact the blocking portion 210. A second opening 250 is provided on the sidewall of the vibration zone 200, and the vibration zone 200 communicates with the Venturi channel 100 through the second opening 250. The second opening 250 is positioned opposite at least one blocking portion 210. When water from the Venturi channel 100 is injected into the vibration zone 200, the water flow will directly impact at least one blocking portion 210, achieving a flow obstruction and rebound effect.

[0031] In one embodiment, such as Figure 2 and Figure 4 As shown, a baffle 221 is provided in the first opening 220. The baffle 221 divides the first opening 220 into at least two branch outlets 222. When water flows through the first opening 220, the baffle 221 increases the back pressure of the water flow, which can effectively delay the backflow time of the airflow, thereby reducing the pulse frequency of the water outlet, increasing the air intake of the water outlet, and enhancing the perceived force of the pulse.

[0032] In one embodiment, such as Figure 2 As shown, the Venturi channel 100 includes an inlet section 120, a constriction section 130, a throat section 140, and an outlet section 150 connected in sequence. The negative pressure zone 101 is located at the end of the outlet section 150 near the throat section 140. The minimum inner diameter of the inlet section 120 is greater than the maximum inner diameter of the throat section 140. Alternatively, the inlet section 120, the throat section 140, and the outlet section 150 can all be configured as cylindrical structures with uniform diameters. The constriction section 130 gradually tapers from the inlet section 120 towards the throat section 140. The inner diameter of the inlet section 120 is equal to the maximum inner diameter of the constriction section 130, and the inner diameter of the throat section 140 is equal to the minimum inner diameter of the constriction section 130. The inner diameter of the outlet section 150 is greater than the inner diameter of the throat section 140. The Venturi channel 100 connects to the vibration zone 200 via the outlet section 150. The intake channel 110 is located on the side wall of the outlet section 150, opposite to the negative pressure zone 101. Water flows sequentially along the inlet section 120, the constriction section 130, the throat section 140, and the outlet section 150. The water velocity gradually increases along the inlet section 120, the constriction section 130, and the throat section 140, creating negative pressure when the water flows from the throat section 140 into the outlet section 150.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, the flushing nozzle also includes at least one functional channel 400. The first outlet of the first water outlet channel 300 and the second outlet 410 of the functional channel 400 face the same direction. Each functional channel 400 can produce different water patterns, and each functional channel 400 and the first water outlet channel 300 are supplied with water through different water pipes to achieve different water output effects.

[0034] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the rinsing nozzle also includes a main body 500 and a cover 600. The main body 500 has a mounting cavity 510. A first water outlet channel 300 is disposed on the main body 500. A blocking portion 210 is provided inside the mounting cavity 510. The cover 600 has a plug-in portion 610. The shape of the plug-in portion 610 is adapted to the shape of the mounting cavity 510. The plug-in portion 610 is inserted into the mounting cavity 510 and abuts against the blocking portion 210. A vibration zone 200 is defined between the plug-in portion 610 and the mounting cavity 510. If problems such as poor water flow occur in the first water outlet channel 300, the cover 600 can be removed to directly clean the mounting cavity 510 and the first water outlet channel 300.

[0035] Furthermore, the flushing nozzle also includes a connecting pipe 700. A Venturi channel 100 is disposed in the connecting pipe 700. The main body 500 is provided with a insertion channel 520. The insertion channel 520 communicates with the mounting cavity 510. The connecting pipe 700 is inserted into the insertion channel 520. The connecting pipe 700 can be directly removed from the main body 500 for cleaning.
