Description

Technical Field

[0001] This utility model relates to the field of fountain pumps, and in particular to an anti-clogging fountain pump. Background Technology

[0002] A fountain pump is a specialized pump designed for fountain systems, with features tailored to their specific requirements. The working principle of a fountain pump is primarily based on that of a centrifugal pump. When the pump starts, the motor drives the impeller to rotate. This rotation generates centrifugal force, drawing water into the center of the impeller and accelerating it as the impeller rotates. The accelerated water flows outward under the influence of centrifugal force and is discharged through the pump's outlet. In a fountain system, the pump draws water from a lower elevation to a higher one, achieving a certain pressure and flow rate. The water is then transported through pipes to the fountain nozzles, the design and shape of which determine the water spray pattern and shape.

[0003] In current practical applications of fountain pumps, a significant problem is the high impurity content in the return liquid during fountain operation. These impurities mainly include suspended particles, tiny solids, and possibly organic matter. When these impurities enter the fountain system with the water flow, they tend to gradually accumulate at the fountain inlet, forming a blockage. This blockage not only reduces the smoothness of the water flow but also significantly decreases the fountain's water output efficiency, affecting its overall aesthetics and operational performance.

[0004] To address this issue, many fountain systems employ filtration mechanisms to pre-treat the return liquid, aiming to remove impurities. However, while this approach alleviates inlet clogging to some extent, it introduces new challenges. Over time, the filtration mechanism itself can gradually become clogged due to the continuous accumulation of impurities. This not only necessitates regular cleaning and maintenance, increasing operating costs, but in cases of severe clogging, it can also directly cause the fountain system to malfunction, significantly impacting its ease of use and reliability. Utility Model Content

[0005] The main objective of this invention is to provide an anti-clogging fountain pump that can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A clog-resistant fountain pump includes a pump body, a pump casing, and ports. The pump casing is located at the output end of the pump body and is fixedly connected to it. The two ports are located on the side wall and the lower end of the pump body, respectively. Liquid is input through the lower end port and liquid is discharged through the side wall port.

[0008] A filter connection cover is connected to the lower end of the port. The side wall of the filter connection cover has multiple filter holes. The lower end of the filter connection cover is connected to an outer support cover, and the side wall of the outer support cover has multiple through holes. Liquid flows in through the openings and through holes of the outer support cover and is then filtered through the filter connection cover.

[0009] The lower opening of the outer support cover is provided with a first connecting screw, and a frustum-shaped filter cover is connected through the first connecting screw. The upper end of the frustum-shaped filter cover is provided with multiple elastic plates. The inner end of the elastic plates is provided with a cleaning brush facing the filter hole. When the frustum-shaped filter cover rotates, it drives the elastic plates, causing the cleaning brush to clean the blockage at the filter hole, thereby achieving anti-clogging of the equipment.

[0010] A further optional solution is that an inner filter cover is installed inside the frustum-shaped filter cover, and the inner filter cover is fixed to the frustum-shaped filter cover by cable ties. The inner filter cover is designed in a frustum shape to increase the filtration performance of the frustum-shaped filter cover.

[0011] In a further optional embodiment, the side wall of the frustum-shaped filter cover is provided with a second connecting screw that is adapted to the first connecting screw. The frustum-shaped filter cover is divided into a rigid support frame and a filter screen. The side wall of the rigid support frame is provided with multiple through slots, and the filter screen is installed in the through slots. The filter screen faces the through hole of the external support cover.

[0012] In a further optional embodiment, the upper side wall of the filter connection cover is provided with a protrusion, and a screw hole is provided on the protrusion. The outer support cover is fixed to the filter connection cover by bolts, and the outer support cover and the filter connection cover are fixed to the connection flange of the port.

[0013] In a further alternative, multiple elastic sheets are arranged in a ring on a frustum-shaped filter cover. The elastic sheets are elastic metal plates. The cleaning brush is heat-fused and fixed to a rubber gasket. The rubber gasket is fixed to the elastic sheet by bolts.

[0014] As a further alternative, a handle is installed at the upper end of the pump body, and the handle is integrated with the pump body housing.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The filtration system employs a multi-layered filtration design, including filter holes on the filter connection cover, through holes in the outer support cover, and a filter screen inside the frustum-shaped filter cover, effectively improving the pump's filtration efficiency. This multi-stage filtration mechanism progressively blocks and captures impurities, ensuring the liquid entering the pump body is relatively pure, reducing wear on internal pump components caused by impurities, and extending the pump's service life.

[0017] The cleaning and anti-clogging mechanism uses the rotation of the frustum-shaped filter cover to drive the elastic plates and cleaning brushes to clean the filter holes, effectively preventing clogging. This automatic cleaning mechanism not only improves the pump's anti-clogging capability but also reduces the frequency of manual cleaning, lowering maintenance costs.

[0018] The synergistic effect of the filtration and anti-clogging mechanisms enables this fountain pump to maintain efficient filtration while also possessing self-cleaning capabilities. This design not only improves the pump's efficiency and stability but also enhances its ability to adapt to complex working environments, ensuring optimal performance under various water quality conditions.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 - Figure 4 As shown, an anti-clogging fountain pump mainly consists of a pump body 1, a pump casing 3, and ports 4. The pump casing 3 is designed to be installed at the output end of the pump body 1 and is firmly connected to the pump body 1. A port 4 is provided on both the side wall and the lower end of the pump body 1, with the lower port 4 used for liquid input and the side wall port 4 used for liquid discharge.

[0026] To further improve the pump's filtration efficiency, a filter connection cover 5 is connected to the lower port 4. Multiple filter holes 6 are formed on the side wall of the filter connection cover 5, effectively preventing impurities from entering the pump body 1. An outer support cover 7 is connected to the lower end of the filter connection cover 5. The side wall of the outer support cover 7 also has multiple through holes 8, allowing liquid to flow into the pump through the outer support cover 7. Simultaneously, the filter holes 6 on the filter connection cover 5 perform preliminary filtration of the liquid.

[0027] The lower opening of the outer support cover 7 is designed with a first connecting screw hole 9, through which a frustum-shaped filter cover 10 can be connected. The upper end of the frustum-shaped filter cover 10 is designed with multiple elastic plates 11, and the inner end of the elastic plates 11 is equipped with a cleaning brush 12 facing the filter hole 6. When the frustum-shaped filter cover 10 rotates, the elastic plates 11 move accordingly, and the cleaning brush 12 cleans any blockages that may exist in the filter hole 6, thereby effectively preventing the pump body 1 from becoming clogged.

[0028] To enhance filtration, an inner filter cover 14 is installed inside the frustum-shaped filter cover 10.
