[0002] A flower basket fountain is a unique type of fountain. It sprays water jets from nozzles, and a mechanical device drives the nozzles to rotate, causing the water jets to form a shape resembling a flower basket. Ordinary flower basket nozzles simply spray water jets out in a single straight line. They require an external mechanical structure to rotate them to form the flower basket shape, making them more expensive to use. Utility Model Content

[0003] The purpose of this invention is to provide a hydrodynamic self-rotating miniature flower basket fountain nozzle to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a nozzle housing and a sealing plate disposed at the bottom of the nozzle housing, characterized in that: the sealing plate is provided with an external threaded water inlet on the side away from the nozzle housing;

[0005] The sealing plate is connected to a rotating sleeve on the side near the external thread water inlet. One end of the external thread water inlet extends into the interior of the rotating sleeve and is fixedly sleeved with a waterproof bearing that is fixedly connected to the inner cavity of the rotating sleeve. Multiple nozzle holes are equidistantly opened on the top of the nozzle housing, and the nozzle holes are inclined around the circumference of the nozzle housing.

[0006] In a further embodiment, an inner sleeve is fixedly connected to the inside of the nozzle housing, and a filter cotton is snapped into the inside of the inner sleeve.

[0007] In a further embodiment, the inner sleeve is provided with a baffle frame inside, and the central pivot of the baffle frame is screwed to the nozzle housing.

[0008] In a further embodiment, a buffer plate is provided inside the nozzle housing, and the sealing plate and the buffer plate are connected by a round-head screw threaded together.

[0009] In a further embodiment, the plurality of nozzle holes are arranged in a ring at the top of the nozzle housing.

[0010] In a further embodiment, a gasket is provided between the sealing plate and the nozzle housing, and the sealing plate and the nozzle housing are connected by hexagonal screws.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention features an externally threaded water inlet installed inside the rotating sleeve via a waterproof bearing. When external water enters the nozzle housing and is sprayed out through the nozzle hole, the water flow generated by the inclined nozzle hole, due to its tilt angle, causes the nozzle housing to automatically rotate around the externally threaded water inlet as the axis. This eliminates the need for external mechanical drive and reduces costs. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This embodiment discloses a hydrodynamic self-rotating small waist flower basket fountain nozzle, including a nozzle housing 1 and a sealing plate 2 disposed at the bottom of the nozzle housing 1. The sealing plate 2 has an externally threaded water inlet 3 on the side away from the nozzle housing 1. Figure 1 , Figure 2 and Figure 3 As shown in this application, the sealing plate 2 is designed at the bottom opening of the nozzle housing 1 and is fixed with hexagonal screws for sealing the nozzle housing 1. The external threaded water inlet 3 is designed at the sealing plate 2 for connecting with the water outlet of the external pump body, so that the external pump body can deliver water through the external threaded water inlet 3 to the inside of the nozzle housing 1.

[0019] Furthermore, a gasket 11 is provided between the sealing plate 2 and the nozzle housing 1, and the sealing plate 2 and the nozzle housing 1 are connected by hexagonal screws. Figure 1 , Figure 2 and Figure 3As shown, the gasket 11 is designed between the sealing plate 2 and the nozzle housing 1, which can improve the sealing performance between the nozzle housing 1 and the sealing plate 2 and prevent water leakage. The sealing plate 2 and the nozzle housing 1 are connected together by hexagonal screws, which pass through the gasket 11 to fix the gasket 11 between the sealing plate 2 and the nozzle housing 1.

[0020] A deeper sealing plate 2 is connected to a rotating sleeve 4 near the external threaded inlet 3. One end of the external threaded inlet 3 penetrates into the interior of the rotating sleeve 4 and is fixedly fitted with a waterproof bearing 5 that is fixedly connected to the inner cavity of the rotating sleeve 4. Multiple nozzle holes 6 are equidistantly opened on the top of the nozzle housing 1. The nozzle holes 6 are inclined circumferentially around the nozzle housing 1, and the multiple nozzle holes 6 are arranged in a ring on the top of the nozzle housing 1. Figure 1 , Figure 2 and Figure 3 As shown, the rotating sleeve 4 is connected to the center of the sealing plate 2 and communicates with the sealing plate 2. The external thread water inlet 3 is located inside the rotating sleeve 4, and a waterproof bearing 5 is installed between them. The rotating sleeve 4 can rotate around the external thread water inlet 3 as its axis. The nozzle hole 6 is designed on the top of the nozzle housing 1 and communicates with the inner cavity of the nozzle housing 1. When the external thread water inlet 3 is connected to the outlet of the external pump body, when the external pump body supplies water to the inside of the nozzle housing 1 through the external thread water inlet 3, the water is sprayed out through the nozzle hole 6 to form a water column. Since the nozzle hole 6 is designed in a ring arrangement on the top of the nozzle housing 1, and the nozzle... The nozzle 6 is inclined around the nozzle housing 1, with the preferred angle being between 35° and 75°, and the optimal angle being 45°. When water is sprayed out, the angle will generate a thrust on the nozzle housing 1, causing the nozzle housing 1 to drive the sealing plate 2 to rotate. The sealing plate 2 drives the rotating sleeve 4 to rotate around the external threaded water inlet 3, achieving self-rotation without the need for external mechanical structure. After the nozzle housing 1 rotates, the water column sprayed from the nozzle hole 6 also rotates, forming a woven, small, waist-shaped flower basket shape, which improves its aesthetics.

[0021] Furthermore, an inner sleeve 7 is fixedly connected inside the nozzle housing 1, and a filter cotton 8 is snapped into the inner sleeve 7. A barrier frame 9 is also installed inside the inner sleeve 7, and the central shaft of the barrier frame 9 is screwed to the nozzle housing 1. A buffer plate 10 is installed inside the nozzle housing 1, and the sealing plate 2 and the buffer plate 10 are connected by a round-head screw threaded together. Figure 3As shown, the inner sleeve 7 is designed inside the nozzle housing 1 and is welded to the nozzle housing 1. The function of the inner sleeve 7 is to place the filter cotton 8. When water flows through, the filter cotton 8 can filter impurities in the water flow. The barrier frame 9 is designed inside the inner sleeve 7 and its function is to block the filter surface. The buffer plate 10 is fixed to the sealing plate 2 by round head screws. When the sealing plate 2 and the nozzle housing 1 are fixed, the buffer plate 10 is inside the inner sleeve 7. On the one hand, it can buffer the water flow and prevent the water flow from directly impacting the filter cotton 8. On the other hand, it can limit and fix the filter cotton 8.
