Detailed Description

A filter device 100 according to an embodiment of the first aspect of the present utility model is described below with reference to fig. 1-6.

As shown in fig. 1 to 6, a filtering apparatus 100 according to an embodiment of the first aspect of the present utility model includes a housing 1, a liquid outlet pipe 2, a filter material 3, and a communication bracket 4.

Specifically, the housing 1 is formed with a liquid inlet 11 and a liquid outlet 12. The liquid outlet pipe 2 is arranged in the housing 1, and the liquid outlet pipe 2 is provided with a first liquid outlet channel 21, and the first liquid outlet channel 21 is respectively communicated with the interior of the housing 1 and the liquid outlet 12. The filter material 3 is filled in the shell 1, and the filter material 3 and the shell 1 jointly define a first liquid inlet channel 31, and the first liquid inlet channel 31 is communicated with the liquid inlet 11. The communication support 4 is arranged in the filter material 3, the communication support 4 is provided with a second liquid inlet channel 43, one end of the second liquid inlet channel 43 is communicated with the first liquid outlet channel 21, and the other end of the second liquid inlet channel 43 and the first liquid inlet channel 31 are respectively positioned at two radial sides of the liquid outlet pipe 2.

For example, in the examples of fig. 1 to 6, the liquid inlet 11 and the liquid outlet 12 are formed at the same end in the longitudinal direction (e.g., the left-right direction in fig. 1) of the housing 1. The drain pipe 2 extends along the length direction of the housing 1 and is located in the middle of the housing 1, the first drain channel 21 extends along the length direction of the drain pipe 2, one end of the length direction of the first drain channel 21 is communicated with the interior of the housing 1, and the other end of the length direction of the first drain channel 21 extends to the end of the housing 1. The filter material 3 is filled around the liquid outlet pipe 2 to filter the liquid entering the shell 1, and the filtered liquid can flow to the first liquid outlet channel 21, then flows to the liquid outlet 12 through the first liquid outlet channel 21, and finally flows out of the shell 1. The second liquid inlet channel 43 of the communication bracket 4 can be communicated with the first liquid outlet channel 21, and liquid in the shell 1 can enter the second liquid inlet channel 43 after being sufficiently filtered by the filter material 3, flows into the first liquid outlet channel 21 through the second liquid inlet channel 43, and finally flows to the liquid outlet 12.

In the prior art, when the filter material 3 is filled in the shell 1, a part of space needs to be reserved to meet the water absorption expansion of the filter material 3, so that the filter material 3 does not need to be completely filled in the shell 1. When the filter device 100 is placed laterally, i.e. the axial direction of the housing 1 (e.g. left-right direction in fig. 1) is parallel to the horizontal plane, the filter material 3 will sink under the influence of gravity, when the upper space of the housing 1 is free of the filter material 3 and a first feed channel 31 is formed. When the liquid flows along the first liquid inlet channel 31, the liquid can directly flow to the liquid outlet pipe 2, so that the liquid in the first liquid inlet channel 31 directly flows out without filtering.

In the present application, by arranging the free end of the second liquid inlet channel 43 and the first liquid inlet channel 31 on two radial sides of the liquid outlet pipe 2, that is, when the filtering device 100 is placed transversely, the first liquid inlet channel 31 is located on the upper side of the housing 1, and the free end of the second liquid inlet channel 43 is located on the lower side of the housing 1, at this time, all the liquid in the housing 1 needs to flow to the lower side of the housing 1 through the filtering material to enter the second liquid inlet channel 43. Then, in the process that part of the liquid passing through the first liquid inlet channel 31 flows from the upper side of the casing 1 to the lower side of the casing 1, part of the liquid which is not filtered can pass through the filter material 3, so that the filtering of the part of the liquid is realized, and then the part of the liquid flows to the first liquid outlet channel 21 through the second liquid inlet channel 43. Therefore, all liquid in the shell can be fully filtered by the filter material 3 and then flows out, and the filtering effect of the filtering device 100 is improved.

Specifically, the liquid enters the housing 1 from the liquid inlet 11, a part of the liquid flows to the filter material 3, and the liquid flows along the length direction of the housing 1 under the impact force, so that the flow can be realized while filtering, and the liquid flows into the second liquid inlet channel 43. Another part of the liquid flows to the first liquid inlet channel 31 and flows along the first liquid inlet channel 31 under the action of self impact force, and the free end of the second liquid inlet channel 43 is positioned at the lower side of the casing 1, so that the other part of the liquid needs to flow to the lower side of the casing 1, and in the process, the other part of the liquid can flow through the filter material 3 in the casing 1 to realize filtration. So far, all the liquid in the shell 1 can be fully filtered, and the filtered liquid flows into the second liquid inlet channel 43 and the first liquid outlet channel 21 in sequence and flows out of the shell 1 through the liquid outlet 12, so that the filtering effect of the filtering device 100 is improved. Meanwhile, the filter material 3 does not need to be excessively added into the shell 1 when the filter device 100 is transversely used, so that the use of the filter material 3 is saved, and the cost is reduced.

The filter material 3 may be a granular filter material, such as resin, activated carbon, or the like.

According to the filtering apparatus 100 of the embodiment of the present utility model, by arranging the communication bracket 4 in the filtering material 3, and communicating one end of the second liquid inlet channel 43 with the first liquid outlet channel 21, the other end of the second liquid inlet channel 43 and the first liquid inlet channel 31 are respectively located at two sides of the radial direction of the liquid outlet pipe 2. Therefore, compared with the conventional water purifier, when the filter device 100 is laterally placed, the liquid flowing through the first liquid inlet channel 31 needs to flow to the lower side of the housing 1 to enter the second liquid inlet channel 43, so that the liquid flowing through the first liquid inlet channel 31 can be sufficiently filtered through the filter material 3, the filtering effect of the filter device 100 is improved, and the use experience of a user is improved.

According to some embodiments of the present utility model, the communication bracket 4 includes a first communication section 41 and a second communication section 42 connected to each other, the first communication section 41 extending in an axial direction (e.g., a left-right direction in fig. 1) of the liquid outlet pipe 2, the first communication section 41 having a first passage section 411. The second communication section 42 extends in the radial direction of the liquid outlet pipe 2, the second communication section 42 has a second passage 421 section, and the second passage 421 section and the first passage section 411 constitute a second liquid inlet passage 43.

Referring to fig. 1 to 3, the first communicating section 41 and the second communicating section 42 are perpendicular to each other, and the first passage section 411 and the second passage section 421 communicate. One end of the first communication section 41 in the longitudinal direction (for example, in the left-right direction in fig. 1) is connected to the liquid outlet pipe 2, and the first passage section 411 is communicated with the first liquid outlet passage 21, so that the second liquid inlet passage 43 is communicated with the first liquid outlet passage 21.

When the filter device 100 is placed laterally, the free end of the second communication section 42 is located at the lower side of the housing 1 and the filtered liquid needs to enter the second liquid inlet channel 43 from the free end of the second communication section 42. Thus, the liquid in the housing 1 needs to flow to the underside of the housing 1 and to the free end of the second communication section 42, so that it can enter the second liquid inlet channel 43. When part of the liquid flows along the first liquid inlet channel 21, it flows from the upper side of the housing 1 to the lower side of the housing 1, can pass through the filter material 3 and be filtered, then reaches the free end of the second communication section 42, and can pass through the second channel section 421, the first channel section 411 and the first liquid outlet channel 21 in this order, and then be discharged out of the housing 1 through the liquid outlet 12.

So set up, can guarantee that all liquid in the shell 1 is through the abundant filtration of filter material 3, make filter equipment 100 more abundant to the filtration of liquid, strengthened filter equipment 100's filter effect.

According to some embodiments of the utility model, the filter device 100 further comprises a filter element 5. As shown in fig. 1, the filter element 5 is connected to the end of the free end of the second communication section 42 by welding, i.e. the filter element 5 covers the free end of the second communication section 42. By the arrangement, the filter material 3 can be prevented from entering the second liquid inlet channel 43 along with liquid, so that the purity of the liquid flowing into the second liquid inlet channel 43 is ensured to be free from impurities, and the second liquid inlet channel 43 is prevented from being blocked by the filter material 3.

According to some embodiments of the present utility model, the communication bracket 4 further includes a support portion 44, the support portion 44 is sleeved on the first communication section 41, the support portion 44 is formed with through holes 441, and the plurality of through holes 441 are spaced apart along the circumferential direction of the liquid outlet tube 2, and in the description of the present utility model, "a plurality of" means two or more. The support portion 44 abuts against the inner wall of the housing 1. For example, in the example of fig. 1 to 4, the cross-section of the support portion 44 is circular in shape, and the axis of the support portion 44 coincides with the axis of the housing 1. The through holes 441 are formed at the surface of the support portion 44, wherein the number of through holes 441 may be 4, and the 4 through holes 441 have an equal area and are arranged at intervals in the circumferential direction of the support portion 44. Thereby, the support portion 44 supports the first communication section 41, so that the positions of the first communication section 41 and the second communication section 42 inside the housing 1 are fixed, and the stability is enhanced. Meanwhile, the arrangement of the through holes 441 prevents the supporting portion 44 from obstructing the flow of the liquid, so that the liquid can flow along the length direction of the housing 1, thereby being fully filtered, further reducing the weight of the supporting portion 44, further reducing the weight of the communication bracket 4, saving production materials and reducing production cost.

Further, one of the supporting portion 44 and the inner wall of the housing 1 is formed with a first limiting groove 442, the other one of the supporting portion 44 and the inner wall of the housing 1 is provided with a first limiting protrusion 16, the first limiting protrusion 16 extends along the axial direction of the liquid outlet pipe 2, and the first limiting protrusion 16 is fitted in the first limiting groove 442. Specifically, when the first stopper groove 442 is formed on the supporting portion 44, the first stopper protrusion 16 (not shown) is provided on the inside of the housing 1. When the first limiting protrusion 16 is disposed on the supporting portion 44, a first limiting groove 442 (as shown in fig. 4) is formed on the inner wall of the housing 1. Therefore, the first limiting protrusion 16 is matched with the first limiting groove 442, so that the limit of the supporting portion 44 is realized, the supporting portion 44 is prevented from rotating in the shell 1, the direction of the free end of the second liquid inlet channel 43 is prevented from being changed, and the supporting effect of the supporting portion 44 on the first communicating section 41 and the second communicating section 42 is further enhanced.

As shown in fig. 4, the supporting portion 44 is formed with a first limiting groove 442, and the inner wall of the housing 1 is provided with a first limiting protrusion 16. The first limiting groove 442 is formed by recessing a radial portion of the sidewall of the supporting portion 44, the first limiting protrusion 16 is disposed on the inner wall of the housing 1, and the first limiting protrusion 16 extends along the length direction of the housing 1. When the communication bracket 4 is installed, the first limiting groove 442 is matched with the first limiting protrusion 16, so that the communication bracket 4 slides along the first limiting protrusion 16 until the first communication section 41 is connected with the liquid outlet pipe 2. By the arrangement, the only installation position of the supporting part 44 can be determined, the supporting part 44 is prevented from rotating in the shell 1 to influence filtration, and the communication bracket 4 is also convenient to install.

According to some embodiments of the present utility model, the communication bracket 4 further comprises a third communication section 45, the third communication section 45 being connected to the junction of the first communication section 41 and the second communication section 42, the third communication section 45 extending in the axial direction of the liquid outlet tube 2, the third communication section 45 having a flow channel 451, the flow channel 451 being in communication with the interior of the housing 1. Referring to fig. 1 to 4, one end of the third communication section 45 is connected to one end of the first communication section 41 away from the liquid outlet pipe 2, and the other end of the third communication section 45 extends along the length direction of the housing 1, so that the supporting effect on the filter material 3 is realized.

The flow passage 451 is formed inside the third communication section 45, and the flow passage 451 extends in the length direction of the third communication section 45. Since the flow passage 451 communicates with the interior of the housing 1, liquid can enter the flow passage 451 from the interior of the housing 1. When the filtering device 100 is placed transversely, the liquid flowing through the first liquid inlet channel 31 can enter the flow channel 451 from the upper side of the third communication section 45, and then flows to the lower side of the third communication section 45 through the flow channel 451, so that the liquid can be filtered by the filter material 3, and the filtering effect of the filtering device 100 on the liquid is improved.

Further, the free end of the third communication section 45 protrudes beyond the end of the filter material 3 in the axial direction of the liquid outlet pipe 2. For example, in the examples of fig. 1 and 2, the end of the third communication section 45 away from the first communication section 41 protrudes out of the end of the filter material 3, so that it is possible to avoid the filter material 3 entering the third communication section 45 and to avoid the clogging of the flow passage 451.

In some alternative embodiments, a plurality of small holes (not shown) are formed on the third communication section 45, when the filtering device 100 is placed transversely, the liquid above the third communication section 45 can also directly enter the flow channel 451 through the small holes on the third communication section 45, and the liquid in the flow channel 451 can flow into the filtering material 3 below the third communication section 45 through the small holes, so as to achieve sufficient filtering of the liquid, and further improve the filtering effect of the filtering device 100.

As shown in fig. 1, 2, 5 and 6, the cover 14 is provided at an end of the housing 13 adjacent to the third communication section 45, and the base 15 is provided at an end of the housing 13 remote from the third communication section 45. The third liquid inlet channel 152 is communicated with the liquid inlet 11 and the interior of the shell 13, so that liquid can enter the interior of the shell 13 through the third liquid inlet channel 152 after passing through the liquid inlet 11. The second liquid outlet channel 153 extends along the axial direction of the base 15 and is connected to the first liquid outlet channel 21, so that the filtered liquid flows into the second liquid outlet channel 153 through the first liquid outlet channel 21 and then flows out of the housing 13 from the liquid outlet 12.

Specifically, when the liquid needs to be filtered, the liquid enters from the liquid inlet 11, flows through the third liquid inlet channel 152 and enters the housing 13, after being filtered in the housing 13, flows through the second liquid inlet channel 43 and the first liquid outlet channel 21 in sequence, and then flows to the liquid outlet 12 through the second liquid outlet channel 153 and is discharged out of the housing 13, so that the filtering device 100 finishes filtering the liquid.

It should be noted that, the filter 5 is also disposed at an end of the housing 13 adjacent to the base 15, so as to prevent the filter material 3 in the housing 13 from flowing out or blocking the second liquid outlet channel 153.

When the second limiting groove 131 is formed on the housing 13, a second limiting protrusion 151 (as shown in fig. 6) is provided on the base 15. Through the cooperation of the second spacing protrusion 151 and the second spacing groove 131, the assembly of the base 15 and the shell 13 can be realized, the assembly firmness of the base 15 and the shell 13 is enhanced, the base 15 or the shell 13 is prevented from rotating, and the tightness of the shell 1 is also improved.

Referring to fig. 6, the base 15 is provided with a second limiting protrusion 151, and the housing 13 is formed with a second limiting groove 131. The second limiting protrusion 151 is provided on an inner wall of the base 15 at a side adjacent to the housing 13, and the second limiting groove 131 is concavely formed by an outer surface of the housing 13. This makes it possible to fix the mounting position of the housing 13 and the base 15, and also fix the mounting position of the communication bracket 4 and the housing 13, thereby fixing the relative positions of the base 15 and the communication bracket 4.
