CENTRIFUGAL FILTER

Abstract

A centrifugal filter comprises a top flow guiding assembly, a water inlet flow guiding assembly, a recessed flow guiding assembly, and an impurity flow guiding assembly, in which a liquid entering from a water inlet opening of the water inlet flow guiding assembly can generate a convolution in an inner portion of the recessed flow guiding assembly. After convoluting to a bottom portion of the recessed flow guiding assembly, heavier impurity components comprised by the liquid flows downwardly into the impurity flow guiding assembly, and the liquid without the impurity components convolutes upwardly. Finally, the top cover portion outwardly discharges the liquid without the impurity components.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Other technical content, characteristics, and effects of the present invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the drawings.

[0015] Please refer to FIGS. 1A to 1C, which are a schematic exploded structure figure, a schematic assembled structure figure, and a schematic cross-sectional structure figure after the assembling of a centrifugal filter of the present invention. It can be known from the figures that the centrifugal filter at least comprises a top flow guiding assembly 1, a water inlet flow guiding assembly 2, a recessed flow guiding assembly 3, and an impurity flow guiding assembly 4.

[0016] In the centrifugal filter, the top flow guiding assembly 1 has a top cover portion 11 at a top portion, wherein the top cover portion 11 downwardly forms a first screw connection column 12, and the first screw connection column 12 downwardly forms a spiral flow guiding column 13, and the surface of the spiral flow guiding column 13 has a plurality of tilted ribs 131, wherein the tilted ribs 131 may form a plurality of spiral flow guiding grooves 132, and the top flow guiding assembly 1 has a first through channel 14 therein capable of passing through the top flow guiding assembly 1.

[0017] In the centrifugal filter, the water inlet flow guiding assembly 2 has a first screw connection portion 21 at a top portion and capable of being screwingly connected to the first screw connection column 12, wherein the screw connection portion 21 has a screw connection wall surface 211 therein, and the screw connection portion 21 downwardly has a water inlet portion 22, and the sidewall surface of the water inlet portion 22 has a water inlet opening 23 thereon capable of passing through the inner portion of the water inlet portion 22, wherein the water inlet portion 22 downwardly forms a second screw connection column 24, and the water inlet flow guiding assembly 2 has a second through channel 25 therein capable of passing through the water inlet flow guiding assembly 2.

[0018] In the centrifugal filter, the recessed flow guiding assembly 3 has a second screw connection portion 31 at a top end and capable of being screwingly connected to the second screw connection column 24, and the bottom end of the recessed flow guiding assembly 3 has a third screw connection column 32, and the inner portion of the recessed flow guiding assembly 3 has a third through channel 33 capable of passing through the recessed flow guiding assembly 3, wherein the third through channel 33 is a channel structure with a wider upper end and a narrower lower end.

[0019] In the centrifugal filter, the impurity flow guiding assembly 4 has a third screw connection portion 41 at a top end and capable of being screwingly connected to the third screw connection column 32, and the inner portion of the impurity flow guiding assembly 4 has a fourth through channel 42 capable of passing through the impurity flow guiding assembly 4.

[0020] In the actual operating status, as shown in FIG. 2, after the top flow guiding assembly 1 is locked with the water inlet flow guiding assembly 2, the position of the water inlet opening 23 corresponds to the positions of the spiral flow guiding grooves 132 of the spiral flow guiding column 13. Thus, after the liquid 5 is injected into the water inlet opening 23 in a high pressure manner, the liquid 5 can be divided into a plurality of flows along the spiral flow guiding grooves 132 to convolute and move downwardly into the third through channel 33.

[0021] Because the specific weights of heavier impurity components comprised by the liquid 5 are greater, the impurity components will continuously collide with the inner walls of the second through channel 25 and the third through channel 33 during the process of convoluting along the spiral flow guiding grooves 132. Hence, the liquid 51 with the impurity components will gradually separate from the liquid 52 without the impurity components. In addition, because the third through channel 33 is a channel structure with a wider upper end and a narrower lower end, the injected liquid will be influenced by the reduced bottom of the third through passage 33 so as to cause the liquid 51 with the impurity components to move downwardly and cause the liquid 52 without the impurity components to stay at the top. Thus, when more liquid 5 is injected, the liquid 52 without the impurity components will naturally convolute upwardly and successively pass the third through channel 33, the second through channel 25, and the first through channel 14. Finally, the top cover portion 11 outwardly discharges the liquid 52 without the impurity components.

[0022] In addition, in the above operation, the existence of the spiral flow guiding grooves 132 are mainly used to cause the liquid 5 to be divided and convolute. The more bends the spiral flow guiding grooves 132 have, the easier the liquid 5 is divided into a plurality of flows, so that the separated impurity components are smaller. Hence, the purpose of effectively separating impurity components can be achieved by designing the shapes of the tilted ribs 131 so as to change the number of the bends and the sizes of the channels of the spiral flow guiding grooves 132.

[0023] Furthermore, because the specific weight of the liquid 51 with the impurity components is greater, the liquid 51 will flow downwardly into the fourth through channel 42. Then, the bottom portion of the impurity flow guiding assembly 4 may further be connected to at least one conduit and is configured to outwardly discharge the liquid with the impurity components through the conduit.

[0024] Compared with other conventional techniques, the advantages of the centrifugal filter provided by the present invention are as follows:

[0025] (1) The present invention can filter shreds or other impurities in the coolant via a device before the coolant enters the motor so as to prevent the motor from being damaged by shreds and other impurities.

[0026] (2) The spiral flow guiding grooves and the channel structure with a wider upper end and a narrower lower end of the centrifugal filter of the present invention can cause the impurity components having greater specific weights to naturally sink and cause the clean water to be discharged upwardly so as to prevent the motor connected to the centrifugal filter from being damaged by shreds and other impurities in the liquid.

[0027] Note that the specifications relating to the above embodiments should be construed as exemplary rather than as limitative of the present disclosure. The equivalent variations and modifications on the structures or the process by reference to the specification and the drawings of the disclosure, or application to the other relevant technology fields directly or indirectly should be construed similarly as falling within the protection scope of the disclosure.
