Abstract
Description
Technical Field
[0001] This application relates to the field of air filters, and more specifically to a novel filter. Background Technology
[0002] In the field of pneumatic components, an air filter is an air source treatment element that filters and discharges moisture from compressed air. The humidity of the processed compressed air is reduced, which can prevent corrosion of the inner wall of the pipeline and the valve core of the pneumatic control components. The air filter mainly includes a valve body, a cyclone vane assembly, a filter element, a water cup, and a drainer. The valve body is equipped with an air inlet and an air outlet. Compressed air enters the valve body through the air inlet, and after passing through the cyclone vane assembly, a cyclone airflow is generated to separate the moisture in the compressed air. The separated moisture is collected in the water cup, and the water in the water cup is discharged from the drainer. The dried compressed air is then filtered for impurities by the filter element and finally discharged from the air outlet. Among them, the Chinese patent with application number "CN201420644972.X" and patent name "Air Filter" includes a valve body, a cyclone blade assembly, a water cup, a water dispenser, a filter element, and a water level monitoring mechanism. The cyclone blade assembly includes a cylinder that is flared in shape with a gradually increasing diameter from top to bottom. A small-diameter connecting part is provided at the upper end of the cylinder. Several cyclone blades are provided on the outer wall of the middle part of the cylinder. A connecting column is provided axially inside the cylinder. A baffle plate is provided at the bottom of the connecting column. The filter element is placed between the small-diameter connecting part and the baffle plate. The water level monitoring mechanism includes an upper connecting part provided on the outer wall of the water cup and a lower connecting part that cooperates with the upper connecting part. An inspection tube is provided between the upper connecting part and the lower connecting part. A plug is provided at the bottom of the lower connecting part. The aforementioned technical solutions are prone to breakage during use because the water plate surface lacks any protective devices. Furthermore, improper installation by the user can easily cause misalignment of the air inlet and outlet, rendering them unusable. Therefore, there is a need for a new type of filter that is easy to use, has a durable, unbreakable body, and a simple structure. Summary of the Invention

[0024] refer to Figures 1 to 3 According to a preferred embodiment of the present invention, the novel filter has the following structure: Figure 1As shown, the novel filter includes a protective cover 10 and a cup body 20. The protective cover 10 is fitted onto the cup body 20 to define the position of the cup body 20. It should be noted that the protective cover 10 has a first opening 101, a first cavity 102, and a second opening 103. The first opening 101 and the second opening 103 are both connected to the first cavity 102, and the first opening 101 and the second opening 103 are respectively located at both ends of the protective cover 10. One end of the cup body 20 abuts against the bottom of the first cavity 102, and the other end passes through the first opening 101 and is placed on the outside. It should be understood by those skilled in the art that the cup body 20 also has a third opening 201, a second cavity 202, and a fourth opening 203. The third opening 201 and the fourth opening 203 are both connected to the second cavity 202, and the fourth opening 203 is also connected to the second opening 103. The end with the third opening 201 is also placed on the outside. Those skilled in the art should understand that one end of the bottom component of the filter is located in the second cavity 202 and close to the fourth opening 203, and the other end passes through the second opening 103 and is placed outside. It should also be noted that the bottom component is a drainage device and can be drained manually.
[0025] It is worth mentioning that the novel filter includes a valve body 30, the cross-sectional structure of which is as follows: Figure 1 As shown, its bottom mates with the end of the cup body 20 where the third opening 201 is located. The connection can be implemented as a threaded connection, meaning the position of the valve body 30 is limited by rotating it. Notably, the bottom of the valve body 30 has a mating cavity, and one side of the valve body 30 has an air inlet channel 301. The air inlet channel 301 communicates with both the outside and the mating cavity. The center of the bottom wall forming the mating cavity also has a protrusion 31. When the mating cavity mates with the end of the cup body 20 where the third opening 201 is located, the protrusion 31 passes through the third opening 201 and is placed in the second cavity 202. It is also worth mentioning that the valve body 30 has an air outlet channel 302. One end of the air outlet channel 302 is located on the side of the valve body 30 away from the air inlet channel 301, and the other end is located at the center of the protrusion 31. Those skilled in the art should understand that external gas enters through the aforementioned inlet channel and exits through the aforementioned air outlet channel 302.
[0026] It should also be noted that the center of the protrusion 31 has a mounting hole 3101, which is connected to the air outlet channel 302. The new filter also includes a filter assembly 40, one end of which cooperates with the mounting hole 3101 of the protrusion 31, and the other end is located in the second cavity 202.
[0027] Specifically, the filter assembly 40 includes a filter element holder 41, a filter element 42, and a baffle plate 43. The filter element can be made of polypropylene fiber, and the pore size can be 45 or 25 μm. The bottom of the filter element holder 41 has a third cavity 4101, which is an annular cavity. The bottom wall of the third cavity 4101 has a connecting post 411. One end of the connecting post 411 is connected to the bottom wall of the third cavity 4101, and the other end extends out of the third cavity 4101 and is placed inside the second cavity 202. The baffle plate 43 has the following structure... Figure 1 As shown, it has a mating hole that mates with the connecting post 411. The connection can be made by threaded fitting or interference fit to define the position of the baffle plate 43. The filter element 42 is sleeved on the connecting post 411, with one end abutting against the bottom wall forming the third cavity 4101 and the other end abutting against the baffle plate 43. Those skilled in the art should understand that the bottom structure of the baffle plate 43 is umbrella-shaped, used to balance the air pressure in the upper and lower parts of the cup body 20 and prevent water from being drawn back by the airflow. It is worth mentioning that the surface of the connecting post 411 also has multiple guide holes. The top of the filter element seat 41 mates with the mounting hole 3101, and the connection can be made by threaded fitting. Furthermore, the end of the filter element seat 41 that mates with the mounting hole 3101 also has a flow hole, which faces the mounting hole 3101.
[0028] It is worth mentioning that the outer wall of the filter element seat 41 located in the second cavity 202 has an annular mounting groove 4102, and the new filter also includes a cyclone impeller 50, which is disposed on the annular mounting groove 4102.
[0029] It should be noted that the size of the first opening 101 of the protective cover 10 is smaller than the cross-sectional size of the cup body 20, and the first opening 101 of the protective cover 10 is expanded by prying it open, so that the bottom of the cup body 20 can pass through the first opening 101 and abut against the bottom of the first cavity 102. In addition, the outer wall of the cup body 20 also has an annular limiting groove. When the end of the first opening 101 is no longer squeezed by the outer wall of the cup body 20, the first opening 101 will shrink, so that the wall surface forming the first opening can cooperate with the annular limiting groove, thereby limiting the position of the protective cover 10.
[0030] Specifically, the top of the valve body 30 also has an inner cavity, and a decorative cover 60 is installed on the top of the valve body 30 to close the inner cavity.
[0031] like Figure 3 As shown, the outer wall of the filter element seat 41 located in the second cavity 202 has an annular tip 411. The annular tip 411 is close to the annular mounting groove 4102. That is, the cyclone impeller 50 is expanded when it passes through the annular tip 411, and then installed into the annular mounting groove 4102, and then disengages from the annular mounting groove 4102 through the annular tip 411.
[0032] It should be noted that the novel filter also includes two opposing connecting blocks 70, located on opposite sides of the valve body. Each connecting block 70 has a connecting hole, one facing the air inlet channel and the other facing the air outlet channel. An external connector can mate with the corresponding connecting hole. Notably, this design of the connecting blocks 70 prevents thread damage at the ends of the air inlet or outlet channels due to improper installation. The replaceable connecting blocks 70 design improves the product's lifespan, and the connecting blocks 70 can be fixed to the valve body using external screws.
[0033] In summary, the novel filter described in the embodiments of this application is explained, which provides advantages such as convenient use, resistance to cup breakage, and simple structure.
[0034] It is worth mentioning that, in the embodiments of this application, the novel filter has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the novel filter 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.
