[0015] In general, compared with the prior art, the above technical solution conceived by the present invention has the following beneficial effects: 1. The self-cleaning chemical plunger pump of the present invention has a filter component arranged. When the filter component is vibrated by the linkage cleaning component, on the one hand, impurities on the filter screen can be vibrated off and flushed by the fluid. On the other hand, when the filter screen moves backward, the first spring can be compressed. When the linkage cleaning component is withdrawn, the first spring can push the filter screen to reciprocate and vibrate, so as to further enhance the vibration effect of the filter screen and enhance the cleaning effect of the filter screen. 2. The self-cleaning chemical plunger pump of the present invention can suck the fluid from the cleaning section into the water inlet pipe and the water outlet pipe after the pump body is opened through the arranged internal drive swinging member. After the fluid enters the internal drive swinging member, it can drive the internal drive impeller to rotate. After the internal drive impeller rotates, it can drive the rotating disk to rotate. After the rotating disk rotates, it can drive the driving rod to rotate. After the driving rod rotates, it can drive the swing rod and the swing hammer to swing back and forth. After the swing rod and the swing hammer swing back and forth, they can effectively vibrate the inner wall of the cleaning pipe, so that the impurities adhered to the inner wall of the cleaning pipe are vibrated and fall off to be flushed and cleaned along with the fluid. The arrangement of multiple groups of external protrusions can further improve the vibration effect of the swing hammer on the inner wall of the cleaning pipe on the one hand, and reduce the resistance caused by the swing hammer directly contacting the inner wall of the cleaning pipe on the other hand, so as to further promote the use of the swing hammer; 3. The self-cleaning chemical plunger pump of the present invention forms a certain fluid pressure when the fluid passes through the first liquid inlet by making the diameter of the first liquid inlet larger than the diameter of the second liquid inlet. The formed fluid pressure can, on the one hand, promote the faster flushing and cleaning of impurities falling from the inner drive swing component, and on the other hand, can impact the filter component to flush and clean the impurities formed in the filter component. The first liquid inlet groove and the second liquid inlet groove arranged up, down, left and right can make the overall liquid inlet of the traction ring more uniform. 4. The self-cleaning chemical plunger pump of the present invention can quickly allow the injected fluid to enter the internal drive swing member through the formed annular liquid inlet channel. By limiting the internal drive impeller to a conical structure, the pressure of the fluid entering from the internal drive swing member can be further increased. On the one hand, the fluid pressurization of the built-in filter plate can be further enhanced, and on the other hand, the internal drive impeller can be quickly rotated. Moreover, by arranging friction channels on multiple groups of sub-sheets of the internal drive impeller, the action time of the fluid on the sub-sheets can be further promoted, so as to once again promote the rotation of the internal drive impeller; 5. The self-cleaning chemical plunger pump of the present invention can drive the second gear to rotate through the arranged linkage cleaning component when the inner drive shaft rotates, so as to drive the first gear and the gear rod to rotate through the connecting belt, and when the gear rod rotates, it can drive the cylindrical cam to rotate, so as to drive the built-in roller to perform continuous rolling operation along the V-groove and the transition arc groove, and at the same time, it can drive the second displacement rod to quickly drive the second displacement rod to perform continuous forward and backward movement. After the second displacement rod performs the forward and backward movement, it can continuously vibrate the entire filter component, and when the filter component is continuously vibrated, the particles adhered to the filter component can be removed. The impurities are shaken off and flushed out along with the fluid, so as to enhance the shaking cleaning effect of the filter component. The cleaning wheel and the conical protrusion can enhance the shaking cleaning effect of the filter component as a whole, and can penetrate the conical protrusion into the filter component as a whole to further insert and clean the mesh inside the filter component. In addition, the linkage cleaning component can continuously shake and clean the filter component, and can prevent the inner drive swing component from blocking the filter component after shaking and cleaning the impurities on the inner wall of the cleaning pipe, so as to further promote the vibration of the cleaning pipe by the inner drive swing component. 6. The self-cleaning chemical plunger pump of the present invention can improve the smoothness of the second displacement rod when it is stretched forward and backward by means of the built-in spring and the built-in pull plate, and can effectively prevent the second displacement rod from being completely pulled out of the first displacement rod so that the linkage cleaning component cannot operate. On the other hand, by limiting the stretching of the second displacement rod, it can prevent the built-in roller from falling off from the V-groove and the transition arc groove due to rapid movement; 7. The self-cleaning chemical plunger pump of the present invention can drive the trigger rod to be stretched one after another through the arranged follower cleaning component when the second displacement rod is stretched one after another, and when the trigger rod moves forward, the upper rotating wheel can slide along the highest point toward the lowest point of the first inclined surface, so that the lower rotating wheel can contact the inner bottom wall of the cleaning pipe, and after the first inclined surface passes through the upper rotating wheel, the lower rotating wheel can be moved up by the second spring, and in addition, when the second displacement rod is pulled back, the second inclined surface can be driven to contact the upper rotating wheel, and when the upper rotating wheel slides along the second inclined surface from the highest point to the lowest point, The lower rotating wheel can be made to contact the inner bottom wall of the cleaning tube again to complete the vibration operation of the inner bottom wall of the cleaning tube. On the one hand, the impurities on the inner bottom wall of the cleaning tube can be vibrated off to be flushed by the fluid to complete the cleaning operation of the inner bottom wall of the cleaning tube. On the other hand, since a part of the impurities are flushed by the fluid when the internal drive swing component oscillates the inner wall of the cleaning tube, the other part of the impurities will fall on the inner bottom wall of the cleaning tube due to gravity. By linking the cleaning component to vibrate the inner bottom wall of the cleaning section, the other part of the impurities that fall due to gravity can be re-vibrated to be flushed by the fluid, thereby further promoting the use effect of the internal drive swing component.

[0022] The present invention is based on an overall idea that, through the arrangement of the filter component 3, when the filter component 3 is vibrated by the linkage cleaning component 5, on the one hand, the impurities on the filter screen 37 can be vibrated off and flushed by the fluid, and on the other hand, when the filter screen 37 moves backward, the first spring 35 can be compressed, and when the linkage cleaning component 5 is retreated, the first spring 35 can push the filter screen 37 to reciprocate and vibrate, so as to further enhance the vibration effect of the filter screen 37 and enhance the cleaning effect of the filter screen 37; through the arrangement of the internal drive swing component 4, after the pump body 1 is turned on, the fluid can be sucked from the cleaning section 2 into the water inlet pipe 11 And the outlet pipe 12, after the fluid enters the inner drive swing component 4, it can drive the inner drive impeller 43 to rotate, and after the inner drive impeller 43 rotates, it can drive the rotating disk 47 to rotate, and after the rotating disk 47 rotates, it can drive the driving rod 48 to rotate, and after the driving rod 48 rotates, it can drive the swing rod 492 and the swing hammer 493 to swing back and forth, and after the swing rod 492 and the swing hammer 493 swing back and forth, they can effectively vibrate the inner wall of the cleaning tube 22, so that the impurities adhering to the inner wall of the cleaning tube 22 are vibrated and fall off to be flushed and cleaned along the fluid, and the multiple sets of external protrusions 494 arranged on the one hand can further improve The vibration effect of the swing hammer 493 on the inner wall of the cleaning tube 22 can, on the other hand, reduce the resistance caused by the swing hammer 493 directly contacting the inner wall of the cleaning tube 22, so as to further promote the use of the swing hammer 493; by making the diameter of the first liquid inlet 461 larger than the diameter of the second liquid inlet 462, a certain fluid pressure can be formed when the fluid passes through the first liquid inlet 461. The formed fluid pressure can, on the one hand, promote the impurities vibrated and dropped from the inner drive swing component 4 to be flushed and cleaned faster, and on the other hand, it can impact the filter component 3 to flush and clean the impurities formed in the filter component 3. The first liquid inlet groove 463 and the second liquid inlet groove 464 are provided, so that the entire traction ring 45 can be more evenly inletted with liquid; through the formed annular liquid inlet channel, the injected fluid can be quickly introduced into the internal drive swing component 4, and the pressure of the fluid entering from the internal drive swing component 4 can be further increased by limiting the internal drive impeller 43 to a conical structure, which can further enhance the fluid pressurization of the built-in filter plate 46 on the one hand, and can make the internal drive impeller 43 rotate quickly on the other hand, and by arranging friction channels on multiple groups of sub-sheets of the internal drive impeller 43, the action time of the fluid on the sub-sheets can be further promoted, so as to once again promote the rotation of the internal drive impeller 43;By means of the arranged linkage cleaning member 5, when the inner drive shaft 42 rotates, the second gear 55 can be driven to rotate, so as to drive the first gear 53 and the gear rod 52 to rotate through the connecting belt 54, and when the gear rod 52 rotates, the cylindrical cam 56 can be driven to rotate, so as to drive the built-in roller 596 to perform continuous rolling operation along the V-groove 57 and the transition arc groove 58, and at the same time, the second displacement rod 592 can be driven to quickly drive the second displacement rod 592 to perform continuous forward and backward movement, and after the second displacement rod 592 performs the forward and backward movement, the filter member 3 as a whole can be continuously vibrated, and after the filter member 3 is continuously vibrated, the impurities adhering to the filter member 3 can be vibrated and removed and flushed out along with the fluid, so as to enhance the vibrating cleaning effect of the filter member 3, and the arranged cleaning wheel 593 and the conical protrusion 594 can enhance the vibrating cleaning effect of the filter member 3 as a whole on the one hand, On the other hand, the conical protrusion 594 can be inserted into the filter element 3 as a whole to further insert and clean the mesh inside the filter element 3. In addition, the arranged linkage cleaning element 5 can continuously vibrate and clean the filter element 3 on the one hand, and on the other hand, it can prevent the internal drive swinging element 4 from being blocked on the filter element 3 after the impurities on the inner wall of the cleaning tube 22 are vibrated and cleaned, so as to further promote the vibration of the cleaning tube 22 by the internal drive swinging element 4; by arranging the built-in spring and the built-in pull plate, on the one hand, the smoothness of the second displacement rod 592 when being stretched back and forth can be improved, and on the other hand, it can effectively prevent the second displacement rod 592 from being completely pulled out of the first displacement rod 591, so that the linkage cleaning element 5 cannot operate. On the other hand, by limiting the stretching of the second displacement rod 592, it can prevent the built-in roller 596 from moving quickly and falling off from the V-groove 57 and the transition arc groove 58;By deploying the follow-up cleaning member 6, when the second displacement rod 592 is stretched forward and backward, the trigger rod 597 can be stretched forward and backward. When the trigger rod 597 moves forward, the upper rotating wheel 63 can slide along the highest point toward the lowest point of the first inclined surface 598, so that the lower rotating wheel 64 can contact the inner bottom wall of the cleaning tube 22. After the first inclined surface 598 passes through the upper rotating wheel 63, the lower rotating wheel 64 can move up due to the second spring 66. In addition, when the second displacement rod 592 is pulled backward, the second inclined surface 599 can be driven to contact the upper rotating wheel 63.

On the one hand, the impurities on the inner bottom wall of the cleaning tube 22 can be vibrated off to be flushed by the fluid to complete the cleaning operation of the inner bottom wall of the cleaning tube 22. On the other hand, since the inner drive swing member 4 oscillates the inner side wall of the cleaning tube 22, part of the impurities are flushed by the fluid, and the other part of the impurities will fall on the inner bottom wall of the cleaning tube 22 due to gravity. Through the vibration of the inner bottom wall of the cleaning section 2 by the linkage cleaning member 5, the other part of the impurities falling due to gravity can be re-vibrated to be flushed by the fluid, which further promotes the use effect of the inner drive swing member 4. ;

The filter component 3 includes a filter ring 31, which is detachably installed in the cleaning tube 22, and the filter ring 31 is located on one side of the clamping tube 23; a first sealing ring 32, which is detachably installed on the filter ring 31, and the first sealing ring 32 and the filter ring 31 are connected to each other; a second sealing ring 33, which is detachably arranged on the filter ring 31, and the second sealing ring 33 and the filter ring 31 are connected to each other; two sets of stabilizing rods 34, both of which are detachable The filter plate 37 is slidably installed in the filter ring 31, and the filter plate 37 is located between the first sealing ring 32 and the second sealing ring 33, and the filter plate 37 can be passed through by the stabilizing rod 34; the first spring 35 is removably arranged on the stabilizing rod 34, and the first spring 35 is located between the second sealing ring 33 and the limit block 36, wherein the stabilizing rod 34 can pass through the filter plate 37 and the first sealing ring 32 in sequence; Next, the overall operating principle of the filter component 3 is further explained. When the filter component 3 is vibrated by the linkage cleaning component 5, on the one hand, the impurities on the filter screen 37 can be vibrated off and flushed by the fluid. On the other hand, when the filter screen 37 moves backward, the first spring 35 can be compressed. When the linkage cleaning component 5 is retreated, the first spring 35 can push the filter screen 37 to reciprocate and vibrate, so as to further enhance the vibration effect of the filter screen 37 and enhance the cleaning effect of the filter screen 37.

[0024] Next, a more specific structure and construction is given to the internal drive swing component 4 as a whole for further explanation.

Four groups of second liquid inlet grooves 464 are formed between the filter plate 46 and the traction ring 45, and the built-in filter plate 46 can be passed through by the inner drive shaft 42; a rotating disk 47, which is detachably mounted on the inner drive shaft 42, and the rotating disk 47 is located on one side of the built-in filter plate 46; a driving rod 48, which is detachably mounted on the rotating disk 47, and the driving rod 48 is located at the edge of the rotating disk 47; a driving arc ring 49, which has a built-in arc groove, and the built-in arc groove can surround the driving rod 48 therein; two groups of fixed seats 491, which can be detachably mounted on the built-in filter plate 46, a swing rod 492 can be slidably arranged in each group of fixed seats 491, and the two groups of swing rods 492 are detachably connected to the driving arc ring 49, and a swing hammer 493 can be detachably mounted on each group of swing rods 492, and a plurality of groups of external protrusions 494 can be detachably mounted on each group of swing hammers 493; Next, the overall use principle of the internal drive swing component 4 is further explained. After the pump body 1 is turned on, the fluid can be sucked from the cleaning section 2 into the water inlet pipe 11 and the water outlet pipe 12. After the fluid enters the internal drive swing component 4, it can drive the internal drive impeller 43 to rotate. After the internal drive impeller 43 rotates, it can drive the rotating disk 47 to rotate. After the rotating disk 47 rotates, it can drive the driving rod 48 to rotate. After the driving rod 48 rotates, it can drive the swing rod 492 and the swing hammer 493 to rotate. The reciprocating swing can effectively vibrate the inner wall of the cleaning tube 22 after the swing rod 492 and the swing hammer 493 swing back and forth, so that the impurities adhering to the inner wall of the cleaning tube 22 are vibrated and fall off to be flushed and cleaned along with the fluid. The multiple groups of external protrusions 494 can, on the one hand, further improve the vibration effect of the swing hammer 493 on the inner wall of the cleaning tube 22, and on the other hand, reduce the resistance caused by the direct contact between the swing hammer 493 and the inner wall of the cleaning tube 22, so as to further promote the use of the swing hammer 493.

[0025] In some embodiments, more specifically, the first liquid inlet 461 corresponds to the second liquid inlet 462, and each group of the first liquid inlet 461 is connected to each group of the second liquid inlet 462, the diameter of the first liquid inlet 461 is larger than the diameter of the second liquid inlet 462, the four groups of the first liquid inlet grooves 463 are respectively located at the upper, lower, left and right four positions of the built-in filter plate 46, and the four groups of the second liquid inlet grooves 464 are respectively located at the upper, lower, left and right four positions of the built-in filter plate 46; By making the caliber of the first liquid inlet 461 larger than the caliber of the second liquid inlet 462, a certain fluid pressure can be formed when the fluid passes through the first liquid inlet 461. The formed fluid pressure can, on the one hand, promote faster flushing and cleaning of impurities that fall from the internal drive swing component 4 through the formed fluid pressure, and on the other hand, it can form an impact on the filter component 3 to flush and clean the impurities formed in the filter component 3. By arranging the first liquid inlet groove 463 and the second liquid inlet groove 464 up, down, left and right, the overall liquid inlet of the traction ring 45 can be made more uniform.

[0026] In some embodiments, more specifically, an annular liquid inlet channel is formed between the inner drive impeller 43 and the inner drive sleeve 41, and the inner drive impeller 43 is located at the initial liquid inlet end of the inner drive sleeve 41, the inner drive impeller 43 is composed of a plurality of groups of sub-sheets arranged along its axial direction, each group of sub-sheets also has a friction channel, and the shape of the inner drive impeller 43 forms a conical structure; Through the formed annular liquid inlet channel, the injected fluid can be quickly introduced into the internally driven swinging component 4, and by limiting the internally driven impeller 43 to a conical structure, the pressure of the fluid entering from the internally driven swinging component 4 can be further increased. On the one hand, the fluid pressurization of the built-in filter plate 46 can be further enhanced, and on the other hand, the internally driven impeller 43 can be quickly rotated. Moreover, by arranging friction channels on multiple groups of sub-sheets of the internally driven impeller 43, the action time of the fluid on the sub-sheets can be further prolonged, thereby once again promoting the rotation of the internally driven impeller 43.

[0027] In some embodiments, more specifically, in order to enable the swing hammer 493 to touch the inner wall of the cleaning tube 22 when moving left or right, the length of the driving arc ring 49 is adapted to the cross-sectional circular diameter of the rotating disk 47, and the two groups of swing hammers 493 can slide along the two groups of fixed seats 491, and can touch the inner wall of the cleaning tube 22 when one group of swing hammers 493 moves to the left.

[0028] Next, the linkage cleaning component 5 is given a more specific structure and construction as a whole for further explanation.

When the inner drive shaft 42 rotates, the second gear 55 can be driven to rotate, so as to drive the first gear 53 and the gear rod 52 to rotate through the connecting belt 54. When the gear rod 52 rotates, the cylindrical cam 56 can be driven to rotate, so as to drive the built-in roller 596 to perform continuous rolling operations along the V-groove 57 and the transition arc groove 58. At the same time, the second displacement rod 592 can be driven to quickly drive the second displacement rod 592 to perform continuous forward and backward movements. After the second displacement rod 592 performs the forward and backward movements, the filter component 3 can be continuously vibrated as a whole. After the filter component 3 is continuously vibrated, the particles adhered to the filter component 3 can be removed. The impurities on the filter element 3 are vibrated and fall off and are flushed out along with the fluid, so as to enhance the vibrating cleaning effect of the filter element 3; the cleaning wheel 593 and the conical protrusion 594 are arranged, on the one hand, the vibrating cleaning effect of the filter element 3 as a whole can be enhanced; on the other hand, the conical protrusion 594 can be inserted into the filter element 3 as a whole to further insert and clean the mesh inside the filter element 3; in addition, the arranged linkage cleaning element 5 can, on the one hand, continuously vibrate and clean the filter element 3; on the other hand, it can prevent the internally driven swinging element 4 from being blocked on the filter element 3 after vibrating and cleaning the impurities on the inner wall of the cleaning tube 22, so as to further promote the vibration of the cleaning tube 22 by the internally driven swinging element 4.

[0029] In some embodiments, more specifically, a built-in spring is detachably arranged in the first displacement rod 591, and the size of the built-in spring is adapted to the size of the first displacement rod 591, and a built-in pull plate is detachably installed on one end of the second displacement rod 592 that penetrates into the first displacement rod 591, and the built-in pull plate is detachably connected to the built-in spring, and when the built-in roller 596 is located at the highest point of the V-groove 57, the built-in spring is in a natural telescopic state; By arranging the built-in spring and the built-in pull plate, on the one hand, the smoothness of the second displacement rod 592 when being stretched forward and backward can be improved, and on the other hand, it can effectively prevent the second displacement rod 592 from being completely pulled out from the first displacement rod 591, thereby making the linkage cleaning component 5 unable to operate. On the other hand, by limiting the stretching of the second displacement rod 592, it can also prevent the built-in roller 596 from moving quickly and falling off from the V-groove 57 and the transition arc groove 58.

[0030] Next, a more specific structure and construction is given to the whole follow-up cleaning member 6 for further explanation. The follow-up cleaning member 6 includes two groups of sub-follow-up cleaning members and a connecting plate 67. The connecting plate 67 is connected to the two groups of sub-follow-up cleaning members. The sub-follow-up cleaning member includes a cleaning base 61, which is detachably installed in the cleaning tube 22. A cleaning rod 62 is slidably arranged in the cleaning base 61, an upper rotating wheel 63 is rotatably arranged at the top of the cleaning rod 62, and a lower rotating wheel 64 is rotatably arranged at the lower end of the cleaning rod 62; an ear plate 65, which is detachably installed on one end of the cleaning rod 62 that penetrates into the cleaning base 61; a second spring 66, which is detachably installed on the inner top wall of the cleaning base 61, and one end of the second spring 66 is detachably connected to the ear plate 65; Next, the overall working principle of the follow-up cleaning component 6 is further explained. When the second displacement rod 592 is stretched forward and backward, the trigger rod 597 can be stretched forward and backward. When the trigger rod 597 moves forward, the upper rotating wheel 63 can slide along the highest point of the first inclined surface 598 toward the lowest point, so that the lower rotating wheel 64 can contact the inner bottom wall of the cleaning tube 22. After the first inclined surface 598 passes through the upper rotating wheel 63, the lower rotating wheel 64 can move up due to the second spring 66. In addition, when the second displacement rod 592 is pulled backward, the second inclined surface 599 can be driven to contact the upper rotating wheel 63. When the upper rotating wheel 63 moves along the second inclined surface 599 from the highest point to the lowest point, the lower rotating wheel 64 can contact the inner bottom wall of the cleaning tube 22. When the upper and lower parts of the cleaning tube 22 slide toward the lowest point, the lower rotating wheel 64 can contact the inner bottom wall of the cleaning tube 22 again to complete the vibration operation of the inner bottom wall of the cleaning tube 22. On the one hand, the impurities on the inner bottom wall of the cleaning tube 22 can be vibrated off to be flushed by the fluid to complete the cleaning operation of the inner bottom wall of the cleaning tube 22. On the other hand, since the internal drive swing component 4 oscillates the inner wall of the cleaning tube 22, part of the impurities are flushed by the fluid, and the other part of the impurities will fall on the inner bottom wall of the cleaning tube 22 due to gravity. By linking the cleaning component 5 to oscillate the inner bottom wall of the cleaning section 2, the other part of the impurities that fall due to gravity can be re-oscillated to be flushed by the fluid, further promoting the use effect of the internal drive swing component 4.

[0031] In some embodiments, more specifically, the ear plate 65 is located above the lower rotating wheel 64. In the initial position, the lower rotating wheel 64 is located above the inner wall of the cleaning tube 22, the upper rotating wheel 63 and the highest point of the first inclined surface 598 are in conflict with each other, and the size of the upper rotating wheel 63 is adapted to the size of the first inclined surface 598.
