Abstract
Description
Technical Field
[0001] This application relates to the field of pressure regulating filters, and more specifically to a pressure regulating filter assembly. Background Technology
[0002] The structure of existing pressure regulating filter assemblies is as follows: Figure 3 As shown, it includes a movable rod and a spring. The spring is sleeved on the movable rod and is configured to apply a force to the movable rod to limit its position. Those skilled in the art should understand that the top of the movable rod can cooperate with the overflow valve assembly of the pressure regulating filter. The overflow valve assembly is configured to adjust downwards by a predetermined distance to compress the movable rod; conversely, if the predetermined distance is adjusted upwards, the movable rod will return to its original position via the spring. After repeated compression deformation, the spring is prone to permanent deformation, resulting in the movable rod failing to reach its intended position effectively. Therefore, there is a need for a pressure regulating filter assembly with a simple structure, effective repositioning of the moving part, light weight of the moving part, and high practicality.

[0022] refer to Figures 1 to 2 According to a preferred embodiment of the present invention, the pressure regulating filter assembly has the following structure: Figure 1 As shown, the pressure regulating filter assembly includes a movable component 10, which has a fixed rod 11 and a movable block 12. The movable block 12 is connected to the top rod. Specifically, the fixed rod 11 and the movable block 12 are integrally formed, and the movable component 10 has a columnar structure.
[0023] Specifically, the movable block 12 has a mating part 121 and an extension part 122. The extension part 122 is integrally formed with the mating part 121. One end of the mating part 121 also has a first protrusion 1221. The first protrusion 1221 is connected to the fixed rod 11. The mating part 121 also has an annular guide surface 1211. The annular guide surface 1211 is a slope, that is, the size of the annular guide surface 1211 gradually decreases from one end near the first protrusion 1221 to the other end.
[0024] Specifically, the pressure regulating filter assembly further includes a sleeve 20, which is connected to the mating portion 121 of the movable block 12. That is, one end of the sleeve 20 also has a first mating cavity 201, and the bottom wall forming the first mating cavity 201 also has a connecting hole 202. The connecting hole 202 communicates with the outside and the first mating cavity 201 respectively. It is worth mentioning that the wall surface forming the first mating cavity 201 also has an annular pressing surface 2011, which is configured to mate with the annular guide surface 1211, thereby defining the position of the sleeve 20. When the aforementioned sleeve 20 is installed with the mating part 121 of the movable block 12, the annular extrusion surface 2011 can receive external force and expand outward by a predetermined size, so that the mating part 121 of the movable block 12 can be placed in the first mating cavity 201. At this time, the annular extrusion surface 2011 contacts the annular guide surface 1211, and the first protrusion 1221 is placed in the connecting hole 202.
[0025] Specifically, the pressure regulating filter assembly further includes an elastic element 30, which is sleeved on the extension 122 of the movable block 12. At the same time, the end of the elastic element 30 also abuts against the end of the sleeve 20 where the first mating cavity 201 is provided, so as to limit one end of the elastic element 30.
[0026] Specifically, the pressure regulating filter assembly further includes a connector 40, which has an insertion part 41 and a connecting end 42. The insertion part 41 is connected to the connecting end, i.e., integrally formed. Specifically, the end of the extension 122 opposite to the mating part 121 also has a second mating cavity 12201. The connecting end 42 is placed inside the second mating cavity 12201, and the other end is placed outside. It is worth mentioning that a sealing ring 50 is also fitted on the insertion part 41, and the sealing ring 50 is placed inside the second mating cavity 12201 and is pressed to form the wall of the second mating cavity 12201. At the same time, the end of the connecting end 42 opposite to the insertion part 41 is spaced at a predetermined distance from the wall forming the second mating cavity 12201.
[0027] It should be noted that this application is used in conjunction with the valve body 60 and filter element seat 70 disposed in the pressure regulating filter. Those skilled in the art should understand that the structure of the valve body 60 and the filter element seat 70 is as follows: Figure 2 As shown, the cross-sectional structure of the valve body 60 is as follows: Figure 2 As shown, its bottom mates with the end of the water cup 80, and the connection can be implemented as a threaded connection, that is, the position of the valve body 60 is limited by rotating the valve body 60. It is worth mentioning that the bottom of the valve body 60 has a third mating cavity 602, and one side of the valve body 60 has an air inlet channel 601. The air inlet channel 601 is connected to both the outside and the third mating cavity 602. The bottom wall of the third mating cavity 602 also has a second protrusion 6021 at its center. When the mating cavity 602 mates with the end of the cup, the second protrusion 6021 is placed inside the water cup 80. It is also worth mentioning that the valve body 60 has an air outlet channel 603. One end of the air outlet channel 603 is located on the side of the valve body 60 away from the air inlet channel 601, and the other end is located at the center of the second protrusion 6021. That is, those skilled in the art should understand that external gas enters through the air inlet channel and exits through the air outlet channel 603.
[0028] Additionally, it should be noted that the center of the second protrusion 6021 also has a first mounting hole 604, which is connected to the air outlet channel 603. The top of the filter element seat 70 is threadedly connected to the first mounting hole 604, and the bottom wall forming the first mounting hole 604 also has an insertion hole 605. The top of the valve body 60 has a connecting hole 202, and the insertion hole 605 is connected to both the connecting hole 202 and the insertion hole 605. It should be noted that the end of the fixed rod 11 facing away from the movable block 12 passes through the air outlet channel 603 and the insertion hole 605 in sequence, and is placed inside the connecting hole 202. Figure 2 As shown, the fixed rod 11 is also fitted with a sealing ring, which is placed inside the insertion hole 605. A pressure plate is also installed on the sealing ring to limit its position. The fixed rod 11 also passes through the pressure plate. The sealing ring is used to limit the air outlet channel 603 and the insertion hole 605.
[0029] Among them, such as Figure 2As shown, the bottom wall forming the first mounting hole 604 also has an annular tip 6041, which abuts against the surface of the sleeve 20 to define the position of the movable member 10. The top of the filter element seat 70 has a second mounting hole 701, which faces the first mounting hole 604. The end of the elastic member 30 facing away from the sleeve 20 abuts against the bottom wall forming the second mounting hole 701 to define the position of the elastic member 30. Notably, the bottom wall forming the second mounting hole 701 also has a third protrusion 7011, with a positioning hole 702 at its center. The insertion portion 41 of the connector 40 mates with the positioning hole 702, which can be implemented as a threaded connection. Simultaneously, a sealing member fitted onto the insertion portion 41 abuts against the third protrusion 7011.
[0030] It should be noted that the top of the mating part 121 also has an air inlet 12101, which is connected to the air outlet channel 603 and the second mating cavity 12201. Those skilled in the art should understand that external gas passes through the air inlet channel 601 and the filter element seat 70 in sequence. The top of the fixed rod 11 can be pushed upward a predetermined distance by the pressure of the pressure regulating filter component placed there, thereby creating a gap between the annular tip 6041 and the sleeve 20 to provide an external gas passage. When the pressure on the top of the fixed rod 11 decreases, the fixed rod 11 can move upward a predetermined distance by the force of the elastic member 30. At this time, the gap between the annular tip 6041 and the sleeve 20 will decrease, that is, the air pressure at the air outlet channel 603 is adjusted by the gap between the annular tip 6041 and the sleeve 20. It is worth mentioning that the above-mentioned air inlet 12101 allows the gas entering the second mating cavity 12201 to exert a force on the extension 122. That is, when the elastic element 30 fails, a gap is generated between the annular tip 6041 and the sleeve 20. The air inlet 12101 allows the gas in the second mating cavity 12201 to exert a force on the extension 122, so that the annular tip 6041 and the sleeve 20 are tightly pressed together.
[0031] In summary, the voltage regulating filter assembly described in the embodiments of this application is explained, which provides advantages such as simple structure, effective repositioning of moving parts, light weight of moving parts, and high practicality.
[0032] It is worth mentioning that, in this embodiment, the pressure regulating filter assembly has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the pressure regulating filter assembly provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.
