Description

Technical Field

[0001] This application relates to the field of air source components, and more specifically to a head assembly of a pressure regulating filter. Background Technology

[0002] In pneumatic technology, air filters, pressure reducing valves, and lubricators are known as the three major pneumatic components. To achieve multiple functions, these three air source processing components are often assembled together in sequence. The function of an air filter is to remove liquid water, oil, and impurities from compressed air. An air filter typically includes components such as a housing, filter element, cyclone blades, baffle plate, water cup, and drain valve. Its principle is that compressed air forms a rotating airflow after being guided by the cyclone blades. Under the action of centrifugal force, the liquid water, oil, and impurities contained in the air are thrown onto the inner wall of the water cup, flow along the cup wall to the bottom, and are discharged through the drain valve. The compressed air, after the liquid oil, water, and impurities have been removed, passes through the filter element to further remove fine solid particles. Existing pneumatic air filters typically use a pressing method for drainage, where a spring force causes the bottom of the drainer to move up and down, thus achieving drainage. However, the spring will fail after a certain period of use, causing it to lose its grip on the drainer and preventing it from sealing the bottom of the water cup. Therefore, there is a need for a rotating, maintenance-free, and easy-to-use pressure regulating filter head assembly. Summary of the Invention

[0023] Indicative head assembly of a pressure regulating filter

[0024] refer to Figures 1 to 2 According to a preferred embodiment of the present invention, the head assembly of the pressure regulating filter is as follows: Figure 1 As shown, it should be noted that the head assembly of the pressure regulating filter is disposed on the housing of the external pressure regulating filter, wherein the surface structure of the external pressure regulating filter is as follows. Figure 1 As shown, it includes a shell 10 and a water cup 20. The water cup 20 is fitted inside the shell 10 and also mates with the bottom of the shell 10 and the bottom of the water cup 20. Specifically, the bottom of the shell has a first opening 102 and a first cavity 101, with the first opening 102 communicating with the first cavity 101. The bottom of the water cup 20 has a second opening 202 and a second cavity 201, with the second opening 202 also communicating with the first opening 102 and the second opening 202 communicating with the second cavity 201.

[0025] Specifically, the head assembly of the pressure regulating filter includes a connector 30, one end of which is located in the second cavity 201, and the other end is located in the first opening 102. The connector 30 has a stop portion 31 and at least two snap-fit ​​portions 32. The stop portion 31 is connected to the two snap-fit ​​portions 32, and the stop portion 31 abuts against the bottom of the second cavity 201. Both snap-fit ​​portions 32 pass through the second opening 202 and are positioned within the first opening 102. Notably, each snap-fit ​​portion 32 has an extension end and a limiting end. The extension end is connected to the limiting end, and both limiting ends are positioned within the second opening 202 and the first opening 102, spaced a predetermined distance from the end of the water cup 20 with the second opening 202. It is worth noting that the distance between the two limiting ends is greater than the size of the second opening 202, thereby defining the position of the connector 30. Those skilled in the art should understand that the positioning of the two snap-fit ​​portions 32 can be influenced by the formation of the... The walls of the second opening 202 are pressed together, causing the two limiting ends to swing towards each other at a predetermined angle, thereby reducing the distance between the two limiting ends. This allows the two limiting ends to pass through the second opening 202 and be placed in the first opening 102. It should be noted that the locking part 32 is arc-shaped, and each of the two limiting ends has a guide surface at the opposite ends. The guide surface is inclined, meaning that the guide surface can contact a corner of the second opening 202, and the walls of the second opening 202 press against the guide surface, causing the two limiting ends to swing towards each other.

[0026] Additionally, it should be noted that the connector 30 also has a connecting portion 33, which is located between the two latching portions 32. The connecting portion 33 is spaced apart from the latching portions 32 by a predetermined distance to allow for swing space for subsequent pressure deformation of the latching portions 32. The length of the connecting portion 33 is greater than the length of the latching portions 32. The end of the connecting portion 33 facing away from the connector 30 also has a connecting hole 3301, and the bottom wall forming the connecting hole 3301 has a mating hole 3302. The end of the connector 30 facing away from the connecting portion 33 has an arc-shaped cavity 3303, which communicates with the mating hole 3302.

[0027] The head 42 assembly of the pressure regulating filter further includes a rotating member 40. The rotating member 40 has a head 42, a mating part 41, and a rotating part 43. The two ends of the mating part 41 are respectively connected to the head 42 and the rotating part 43, and the head 42, the mating part 41, and the rotating part 43 are integrally formed. The structure of the rotating member 40 is as follows: Figure 2As shown, the cross-sections of the head 42, the mating part 41, and the rotating part 43 are circular. Specifically, the rotating part 43 has a first flow hole 401 at the end opposite to the head 42, the bottom of the first flow hole 401 is close to the head 42, and the wall forming the first flow hole 401 also has a second flow hole 402. The end of the head 42 opposite to the mating part 41 also has a third flow hole 403, and the side wall of the head 42 has a fourth flow hole 404. The second flow hole 402 and the fourth flow hole 404 both mate with the third flow hole 403, that is, the second flow hole 402 and the fourth flow hole 404 are both perpendicular to the third flow hole 403. It should be noted that the top of the third flow hole 403 is blocked by a plug, and the head 42 is also fitted with a sealing ring 100, which is located above the fourth flow hole 404. It should be noted that the aforementioned mating part 41 is threadedly connected to the connecting hole 3301, and the rotating part 43 is placed on the outside. That is, the user can twist the aforementioned rotating part 43 to make the rotating part 40 rotate around itself as the center, thereby causing the rotating part 40 to move towards or away from the connecting head 30. That is, when the rotating part 40 moves away from the connecting head 30 a predetermined distance, the aforementioned fourth flow hole 404 will be placed in the connecting hole 3301, and the sealing ring 100 will be placed at the mating hole 3302. Conversely, when the rotating part 40 moves towards the connecting head 30 a predetermined distance, the aforementioned fourth flow hole 404 will be placed in the arc-shaped cavity 3303. At this time, the solution located in the second cavity 201 will flow through the fourth flow hole 404 to the first flow hole 401, thereby causing the solution to flow to the outside.
