Description

Technical Field

[0001] The utility model relates to the technical field of water pumping, in particular to a filtering sink and a water pump. Background Art

[0002] Most tea tables in homes and offices now use bottled water. The silicone hose of a tea table water pump is placed into the bottled water to draw water. Due to its light weight, the hose tends to float in the water and not sink to the bottom of the barrel, preventing the water from being pumped up. Furthermore, foreign matter may be present in the water, which could clog the sinking head during use. To address this issue, a sinking head with a filter has become commercially available. This head, attached to the end of the hose, adds weight, allowing it to sink to the bottom of the barrel. The filter also isolates foreign matter, preventing clogging.

[0003] Although this type of sinker solves the problem of poor water pumping, it can only filter out larger granular impurities and cannot further filter out finer impurities in the water. In addition, the sinker is an integrated molding setting, and it is not easy to clean the internal structure. Utility Model Content

[0025] Please refer to Figure 1-Figure 2 , Figure 1 This is a schematic diagram of the filter sink. Figure 2It is a cross-sectional view of a filter sink. This embodiment provides a filter sink, which includes a connecting portion 1, a filter portion 2 and a filter element 3. The opposite ends of the connecting portion 1 respectively form a water outlet 11 and a first water inlet 12, and the water outlet 11 and the first water inlet 12 are interconnected, so that a water inlet channel 10 is formed in the connecting portion 1. The water inlet channel 10 is used for allowing liquid to pass through the connecting portion 1. The filter element 3 is placed in the water inlet channel 10, and the filter element 3 is used to filter impurities in the liquid. The filter portion 2 includes a ball head 21 and a filter screen 22, wherein one end of the ball head 21 is detachably connected to the connecting portion 1, and the interior of the ball head 21 is interconnected with the water inlet channel 10. The ball head 21 is away from the end connected to the connecting portion 1 to form a second water inlet 210, and the second water inlet 210 is connected to the first water inlet 12 and the water outlet 11. The filter screen 22 covers the second water inlet 210, and the filter screen 22 is used to filter solid particles in the liquid.

[0026] In the usage scenario, the liquid enters from the second water inlet 210, and then the liquid enters the connecting part 1 from the first water inlet 12 after being filtered by the filter mesh 22, and then the liquid is filtered for the second time by the filter element 3. The liquid after the second filtration flows into the water inlet channel 10, and flows out from the water outlet 11 after passing through the water inlet channel 10. In this example, the mesh number of the filter mesh 22 is sixty, which can be used to filter particles with larger diameters such as wine dregs and tea leaves to prevent particles from entering the filter sink and causing the filter sink to be blocked. After being filtered once by the filter mesh 22, the liquid enters the ball head 21, and then enters the connecting part 1. The filter element 3 arranged in the connecting part 1 performs a second filtration on the liquid, so that tiny particles in the liquid are filtered, and then even smaller impurities in the liquid are filtered, further improving the purity of the liquid.

[0027] Since the filter element 3 needs to be replaced after long-term use, when it is necessary to replace the filter element 3, the filter part 2 is disassembled from the connecting part 1, the filter element 3 in the connecting part 1 is taken out, and then a new filter element 3 is put back into the connecting part 1. Finally, the filter part 2 is reconnected to the connecting part 1 to complete the replacement of the filter element 3. In this way, the connecting part 1 and the filter part 2 are detachably connected, which is convenient for replacing the filter element 3 and also convenient for cleaning the inside of the filter sink.

[0028] Please refer to Figure 3 and Figure 4 , Figure 3 A schematic diagram of a ball head. Figure 4 : is a cross-sectional view of the connection part. In this example, the connection part 1 and the ball head 21 are connected by a threaded structure. The connection part 1 and the ball head 21 are respectively provided with a threaded structure, and the connection part 1 and the ball head 21 are detachably connected by the threaded structure.

[0029] In one embodiment, the connecting portion 1 and the filtering portion 2 are both made of titanium-plated material, which makes the connecting portion 1 and the filtering portion 2 highly corrosion-resistant, effectively increasing the service life of the filter sink.

[0030] Please refer to Figure 4 Furthermore, the connecting portion 1 includes a first clamping structure 13, a second clamping structure 14, a third clamping structure 15, and a receiving structure 16, which are connected in sequence. The first clamping structure 13, the second clamping structure 14, the third clamping structure 15, and the receiving structure 16 are internally connected to each other to form a water inlet channel 10. The end of the receiving structure 16 facing away from the third clamping structure 15 is detachably connected to the ball head 21. The filter element 3 is clamped in the receiving structure 16, so that the filter element 3 is located at the end of the connecting portion 1 close to the filter portion 2, which facilitates the removal and replacement of the filter element 3 from the connecting portion 1.

[0031] In this example, the first clamping structure 13 , the second clamping structure 14 , the third clamping structure 15 and the accommodating structure 16 are integrally formed, which facilitates the processing and manufacturing of the connecting portion 1 .

[0032] Please refer to Figure 4 Furthermore, the outer diameter of the first engaging structure 13 is greater than the outer diameter of the second engaging structure 14, forming a first engaging platform 131 at the first engaging structure 13 and the second engaging structure 14. In actual use of the filter sink, a water pipe is sleeved outside the first engaging structure 13 and the second engaging structure 14, and the first engaging platform 131 engages with the inner wall of the water pipe to prevent the water pipe from loosening and falling off. In this example, the outer diameter of the first engaging structure 13 is 7.5 mm, and the outer diameter of the second engaging structure 14 is 6.8 mm.

[0033] Please refer to Figure 4 and Figure 5 , Figure 5It is an enlarged view of part A. In addition, the third clamping structure 15 includes a guide unit 151 and a clamping unit 152. One end of the guide unit 151 is connected to the second clamping structure 14, and the other end of the guide unit 151 is connected to the clamping unit 152. The end of the clamping unit 152 away from the guide unit 151 is connected to the accommodating structure 16. As the guide unit 151 gradually moves away from the second clamping structure 14, the outer diameter of the guide unit 151 gradually increases. The guide unit 151 is used to be compatible with water pipes with larger diameters. When the water pipe is connected to the filter sink, the water pipe is sleeved outside the guide unit 151, and the water pipe of the guide unit 151 is interference fit with the third clamping structure 15 to achieve mutual clamping of the water pipe and the third clamping structure 15. The outer diameter of the clamping unit 152 is smaller than the maximum outer diameter of the guide unit 151, and the outer diameter of the clamping unit 152 is larger than the minimum outer diameter of the guide unit 151. The connection between the clamping unit 152 and the guide unit 151 forms a second clamping platform 153, which is used to clamp the water pipe to prevent it from falling off. In this example, the minimum outer diameter of the guide unit 151 is 6.8mm, the maximum outer diameter of the guide unit 151 is 9.5mm, and the outer diameter of the clamping unit 152 is 9mm. In this way, by setting the connecting part 1 in sections, the connecting part 1 can be compatible with water pipes of different diameters, thereby effectively expanding the use of the filter sink.

[0034] The platform 161 is used to limit the filter element 3 so that the filter element 3 is clamped between the first water inlet 12 and the clamping boss 161, making it easy to remove and replace the filter element 3.

[0035] In another embodiment, the present invention further provides a water pump, which includes the above-mentioned filter sink and has the same beneficial effects, which will not be described in detail here.

[0036] In summary, the detachable connection between the connector 1 and the filter 2 facilitates cleaning of the filter tap. The filter 2 comprises a ball head 21 and a filter screen 22. The filter screen 22 covers the second water inlet 210 of the ball head 21. During use, the filter screen 22 filters larger impurities from the liquid. Simultaneously, a filter element 3 is positioned within the connector 1, providing secondary filtration of the liquid, resulting in a more purified liquid.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
