Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical filter technology, specifically a novel pharmaceutical filter. Background Technology
[0002] A pharmaceutical filter is a medical device used to filter impurities and particles from pharmaceutical solutions. It is commonly used in the pharmaceutical industry to ensure the quality and purity of medicines. The selection of a pharmaceutical filter depends on several factors, including the type of pharmaceutical solution to be filtered, the required filtration precision, and the operating environment.
[0003] In existing chemical filter systems, the pipeline and the chemical filter are usually detachable for easy cleaning. However, to improve the sealing effect between the pipeline and the chemical filter, a clamp is usually used for connection. When using a clamp, tools are needed to tighten the clamp, which makes it inconvenient to quickly connect and fix the pipeline. Utility Model Content
[0004] The purpose of this invention is to provide a novel liquid medicine filter to solve the problem mentioned in the background art that the currently used liquid medicine filters are inconvenient to quickly connect and fix to pipelines.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel liquid medicine filter, comprising: an upper mounting cover and a filter screen, wherein an inlet is connected to one side of the upper mounting cover, a lower mounting cover is provided at the bottom of the upper mounting cover, an outlet is installed on one side of the lower mounting cover, and the filter screen is installed inside the lower mounting cover;
[0006] One end of the liquid inlet and one end of the liquid outlet are connected to a pipe, and one end of the pipe is connected to a plug. The inner wall of the plug is connected to a movable spring through a groove, and one end of the movable spring is connected to a telescopic block that passes through the groove of the plug.
[0007] Preferably, a rotating block is provided on the top of the telescopic block, and the rotating block is connected to the groove of the insert block through a rotating shaft.
[0008] Preferably, a retaining ring is fitted onto the outer side of the insert block, and a top rod is connected through one end of the retaining ring.
[0009] Preferably, an upper fixing block is installed on the outer side of the upper mounting cover, and a movable block is connected to the bottom of the upper fixing block through a groove.
[0010] Preferably, a lower fixing block is installed on the outer side of the lower mounting cover.
[0011] Preferably, a pull rod is connected through one side of the lower fixing block, and a connecting block is connected to one side of the pull rod.
[0012] Preferably, a locking block and a reset block are respectively installed in the groove of the lower fixing block, and a reset spring is connected between the reset block and the groove of the lower fixing block.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this novel liquid filter, the inlet can be connected and fixed to the pipeline, and the plug on one side of the pipeline can be inserted into the retaining ring. At the same time, the rotating block will retract into the groove of the plug under the pressure of the retaining ring. When the plug is inserted into the groove of the retaining ring, the movable spring will return to its original position and push the rotating block into the groove of the retaining ring through the telescopic block. With the cooperation of the retaining ring and the rotating block, the inlet can be quickly connected and fixed to the pipeline, thus facilitating pipeline docking. This is the characteristic of the use of this novel liquid filter.
[0014] 1. In use, this new type of liquid filter only requires inserting the pipeline into one side of the inlet. The rotating block is then pressed by the retaining ring on the outside of the inlet. Under pressure, the rotating block rotates into the groove of the insert block. At the same time, the movable spring is pressed by the telescopic block. After the pipeline is connected to the inlet, the movable spring will return to its original position due to the large internal groove of the retaining ring. The telescopic block then pushes the rotating block to rotate in the opposite direction, moving it out of the groove of the insert block and into the inside of the retaining ring. The limiting effect of the rotating block allows for quick and easy connection and fixation of the pipeline to the inlet.
[0015] 2. In use, this new type of liquid filter allows users to pull a lever as needed. The lever pulls the protrusion at the bottom of the movable block via a connecting block. The movable block then rotates via a pivot and misaligns with the locking block in the groove of the lower fixed block. This allows the upper and lower fixed blocks to be separated, facilitating quick and easy disassembly of the upper and lower mounting covers and easy replacement of the internal filter screen.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-3 This utility model provides a technical solution: a novel liquid medicine filter, comprising: an upper mounting cover 1 and a filter screen 5, an inlet 2 connected to one side of the upper mounting cover 1, a lower mounting cover 3 provided at the bottom of the upper mounting cover 1, an outlet 4 installed on one side of the lower mounting cover 3, and the filter screen 5 installed inside the lower mounting cover 3.
[0025] One end of the inlet 2 and the outlet 4 are connected to a pipe 6. One end of the pipe 6 is connected to a plug 7. The inner wall of the plug 7 is connected to a movable spring 8 through a groove. One end of the movable spring 8 is connected to a telescopic block 9 that passes through the groove of the plug 7. A rotating block 10 is provided on the top of the telescopic block 9. The rotating block 10 is connected to the groove of the plug 7 through a rotating shaft. A retaining ring 11 is fitted on the outside of the plug 7. One end of the retaining ring 11 is connected to a top rod 12. The plug 7 is inserted into the inside of the retaining ring 11 through the groove.
[0026] In practical implementation, when the new type of liquid filter needs to connect the pipeline 6 to the corresponding liquid inlet 2, only one end of the pipeline 6 needs to be inserted into one end of the liquid inlet 2. At this time, the insert 7 on one side of the pipeline 6 will be inserted into the inside of the retaining ring 11. Under the pressure of the inner wall of the retaining ring 11, the rotating block 10 at one end of the insert 7 will rotate into the groove of the insert 7 through the rotating shaft, and at the same time, it will squeeze the telescopic block 9 in the groove. The telescopic block 9 will retract into the groove of the insert 7 under the pressure, and squeeze the movable spring 8 in the groove.
[0027] When the rotating block 10 moves into the groove inside the retaining ring 11 along with the insert block 7, the groove on the inner wall of the retaining ring 11 is relatively large. Therefore, under the reset action of the movable spring 8, the telescopic block 9 pushes the rotating block 10 to rotate in the opposite direction and locks the rotating block 10 into the groove on the inner wall of the retaining ring 11. Due to the limiting effect of the retaining ring 11 on the rotating block 10, the pipe 6 can be quickly connected to the liquid inlet 2. At the same time, the sealing ring in the groove of the pipe 6 can increase the sealing effect between the pipe 6 and the liquid inlet 2. Similarly, repeating the above steps can quickly connect the pipe 6 to the liquid outlet 4, which facilitates the quick connection of the pipe 6 and increases the connection strength between the pipe 6 and the filter.
[0028] Conversely, simply press the push rod 12 into the inside of the retaining ring 11 so that the push rod 12 presses the rotating block 10 into the groove of the insert block 7. Without the rotating block 10 limiting the insert block 7, the pipeline 6 can be removed from the liquid inlet 2.
[0029] See Figure 1 , Figure 3 and Figure 4 It can be seen that when it is necessary to quickly connect the pipe 6, simply insert the pipe 6 into one side of the inlet 2, and squeeze the rotating block 10 through the retaining ring 11 on the outside of the inlet 2, so that the rotating block 10 rotates and retracts into the groove of the insert 7. At the same time, the movable spring 8 is squeezed by the telescopic block 9. When the pipe 6 and the inlet 2 are connected, the movable spring 8 will push the rotating block 10 out of the groove of the insert 7 through the telescopic block 9. Under the limiting effect of the rotating block 10, the pipe 6 and the inlet 2 can be quickly connected and fixed.
[0030] An upper fixing block 13 is installed on the outer side of the upper mounting cover 1. A movable block 14 is connected to the bottom of the upper fixing block 13 through a groove. A lower fixing block 15 is installed on the outer side of the lower mounting cover 3. A pull rod 16 is connected through one side of the lower fixing block 15. A connecting block 17 is connected to one side of the pull rod 16. A locking block 18 and a reset block 19 are installed in the groove of the lower fixing block 15. A reset spring 20 is connected between the reset block 19 and the groove of the lower fixing block 15. The top of the movable block 14 is connected to the groove of the upper fixing block 13 through a pivot.
[0031] In practical implementation, when the filter screen 5 in the upper mounting cover 1 and the lower mounting cover 3 needs to be replaced, the pull rod 16 is simply pulled to the outside of the lower fixing block 15. The movement of the pull rod 16 will drive the connecting block 17 to move. Since the connecting block 17 is located on the protruding side of the bottom of the movable block 14, the movement of the connecting block 17 will pull the movable block 14 to move, so that the movable block 14 rotates through the rotating shaft in the groove of the upper fixing block 13. When the movable block 14 and the locking block 18 in the groove of the lower fixing block 15 are misaligned, the locking block 18 will no longer limit the movable block 14. Then the movable block 14 can be moved out of the groove of the lower fixing block 15, so that the upper fixing block 13 and the lower fixing block 15 are separated, thereby facilitating the quick disassembly and separation of the upper mounting cover 1 and the lower mounting cover 3, and facilitating the replacement of the filter screen 5 inside the upper mounting cover 1 and the lower mounting cover 3.
[0032] Conversely, simply align the upper mounting cover 1 with the lower mounting cover 3 so that the movable block 14 at the bottom of the upper fixing block 13 is inserted into the interior of the lower fixing block 15. Since the bottom of the movable block 14 is a sloping structure, during the insertion of the movable block 14, the movable block 14 will be squeezed by the locking block 18 and then rotated through the rotating shaft, squeezing the reset block 19 in the groove of the lower fixing block 15, causing the reset block 19 to retract into the groove of the lower fixing block 15, and simultaneously squeezing the reset spring 20 in the groove of the lower fixing block 15.
[0033] When the movable block 14 and the locking block 18 are misaligned, the reset spring 20 will push the movable block 14 to rotate in the opposite direction through the reset block 19, so that the movable block 14 and the locking block 18 can be docked. The movable block 14 can be fixed inside the lower fixing block 15 by the limiting effect of the locking block 18. At this time, the upper mounting cover 1 and the lower mounting cover 3 can be installed and fixed.
[0034] See Figure 1 , Figure 2 , Figure 5 and Figure 6 As can be seen, during use, the lever 16 can be pulled according to the usage requirements, so that the lever 16 drives the connecting block 17 to move. The movement of the connecting block 17 will pull the movable block 14 to rotate through the protruding part at the bottom of the movable block 14. When the movable block 14 is misaligned with the locking block 18 in the groove of the lower fixed block 15, the upper fixed block 13 and the lower fixed block 15 can be separated, so as to facilitate the quick disassembly and separation of the upper mounting cover 1 and the lower mounting cover 3, and at the same time facilitate the replacement of the internal filter screen 5.
[0035] In summary, when using this novel liquid filter, the upper mounting cover 1 and the lower mounting cover 3 can be connected and fixed. Then, pipes 6 are connected to both the inlet 2 and the outlet 4. When the liquid flows through the pipes 6 and the inlet 2 into the cavity between the upper mounting cover 1 and the lower mounting cover 3, it will be filtered through the filter screen 5 inside the upper mounting cover 1 and the lower mounting cover 3. After filtration, the liquid is discharged through the outlet 4 and the pipes 6, thus completing the entire liquid filtration process. This is the characteristic of the use of this novel liquid filter. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
