Description

Technical Field

[0001] This utility model belongs to the technical field of toilet cleaner gel guns, specifically relating to a propulsion mechanism for a toilet cleaner gel gun and a toilet cleaner gel gun. Background Technology

[0002] Chinese utility model patent CN214987198U, published on December 3, 2021, discloses a type of extrusion tube. The tube includes a gel cylinder with a discharge port at one end and an opening at the other end for inserting one end of a push rod, with the other end of the push rod exposed outside the gel cylinder. It also includes an end cap connected to the gel cylinder, with the push rod axially passing through the end cap. Several protrusion structures are provided on the push rod, with adjacent protrusion structures circumferentially distributed and axially spaced between them. A radially recessed notch is provided on the end cap for the protrusion structures to pass through. While this type of toilet cleaner extrusion tube can quantitatively extrude gel, it requires two hands to operate, and each extrusion requires rotating the push rod to align the protrusions with the notch, making the operation inconvenient.

[0003] While existing caulking guns can be used to apply caulking glue with one hand, they are all made of metal, have complex structures, are prone to mechanical failures, and have high production costs. Utility Model Content

[0004] The purpose of this utility model is to provide a toilet cleaner gel gun with a simple structure, low production cost, easy manufacturing, and convenient operation. It can dispense a precise amount of gel and can be operated with just one hand. To solve the above-mentioned technical problems, the technical solution adopted by this utility model is:

[0005] A propulsion mechanism for a toilet cleaner gel gun includes a push rod, a handle, a push rod mounting part, and a rotating rod. The push rod mounting part is fixedly connected to the upper end of the handle and has a horizontal mounting hole that penetrates the part. The push rod can slide within the mounting hole. The rotating rod is hinged to the handle. The push rod has multiple protruding teeth. The rotating rod can push the teeth to make the push rod slide on the handle. An annular boss is provided on the front side of the mounting hole. An elastic rubber ring is fitted on the annular boss. The elastic rubber ring has inclined protrusions that engage with the protruding teeth and restrict the push rod from retracting. The elastic rubber ring can fix and guide the forward direction of the push rod and restrict its retraction. Compared with general mechanical structures, the elastic rubber ring provides smoother guidance, is easier to install, has a simpler structure, and lower production costs.

[0006] Furthermore, the elastic rubber ring has a groove that matches the boss, and the elastic rubber ring is fitted onto the annular boss on the front side of the mounting hole through the groove. With this structure, the connection relationship of the elastic rubber ring is simple, facilitating production and installation, while also offering superior stability.

[0007] Furthermore, a connecting cover is provided on the front side of the push rod mounting part. The connecting cover is open at both ends and has a partition in the middle. The partition contacts the end of the elastic rubber ring away from the groove. The partition has a hole for the push rod to pass through. The end of the connecting cover near the elastic rubber ring is fitted onto the push rod mounting part. The connecting cover can reinforce the elastic rubber ring and can also be used to connect a container containing toilet cleaner gel.

[0008] Furthermore, the rotating rod includes a pressing part and a pushing part connected together. The hinge axis connecting the rotating rod to the handle is located at the upper end of the handle, and the hinge axis is located at the connection point of the pressing part and the pushing part on the rotating rod. Holding the handle and the pressing part with one hand, pressing the pressing part completes the advancement.

[0009] Furthermore, the protruding teeth are evenly spaced on the bottom surface of the push rod, and each protruding tooth is in the shape of an inverted right-angled trapezoid. The pushing part is made of elastic material and is V-shaped, located between two protruding teeth. Each push can return the pushing part to its original position between two protruding teeth, allowing for the next push.

[0010] Furthermore, a torsion spring is fitted onto the hinge shaft, with both ends of the torsion spring extending to the lower ends of the grip and the pressing part, respectively. After the pressing part is pressed, the torsion spring can provide a driving force for the pressing part and the pushing part to return to their original shape.

[0011] Furthermore, a window is provided at the connection between the push rod mounting part and the handle. The handle has a stationary limiting part, and the rotating rod also has a rotation limiting part. The pushing part and the rotation limiting part are located within the window. The rotation limiting part, the stationary limiting part, and the window fix the rotation trajectory of the rotating rod and the pushing part. At the same time, the process of the pushing part pushing the push rod can be clearly seen through the window, which also facilitates repair in case of problems.

[0012] A toilet cleaner gel gun includes a gel cartridge and the aforementioned propulsion mechanism. The gel cartridge is connected to a connecting cap, and a dispensing port is provided at the end of the gel cartridge away from the connecting cap. A push rod is advanced with one hand, pushing the gel and dispensing the toilet cleaner gel from the gel cartridge through the dispensing port.

[0013] Furthermore, the discharge port protrudes outward, and a baffle is provided around the discharge port. A piston plate is provided inside the gel tube, and the piston plate is located at the end of the push rod. The piston plate forms a sealing fit with the inner wall of the gel tube. One end of the piston plate connected to the push rod has an insertion groove adapted to the push rod, and the end of the piston plate away from the push rod protrudes outward to fit the discharge port. The outward protrusion of the discharge port facilitates discharge.

[0014] Furthermore, the toilet cleaner gel gun also includes a cap, the center of which has a protrusion adapted to the dispensing port, and the periphery of which has a groove adapted to the baffle. The cap also has a lever for easy opening. The lever on the cap facilitates opening and installing the cap.

[0027] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] like Figure 1-6 As shown, the present invention provides a propulsion mechanism for a toilet cleaner gel gun and a toilet cleaner gel gun. The propulsion mechanism includes a push rod 1, a handle 21, a push rod mounting part 22, and a rotating rod 3. The push rod mounting part 22 is fixedly connected to the upper end of the handle 21. The push rod mounting part 22 has a horizontal mounting hole 221 that penetrates the push rod mounting part 22. The push rod 1 can slide within the mounting hole 221. The rotating rod 3 is hinged to the handle 21. The push rod 1 has a tooth 11. The convex teeth 11 are provided in multiple ways. The rotating rod 3 can push the convex teeth 11 to make the push rod 1 slide on the push rod mounting part 22. An elastic rubber ring 4 is fixedly connected to the front side of the mounting hole 221. The elastic rubber ring 4 is provided with an inclined protrusion 41. The protrusion 41 engages with the convex teeth 11. The protrusion 41 can restrict the push rod 1 from moving backward. Hold the handle 21 and the rotating rod 3 with one hand and press the lower end of the rotating rod 3 backward. The upper end of the rotating rod 3 rotates forward and pushes the convex teeth 11 to make the push rod 1 move forward.

[0030] The inner ring of the elastic rubber ring 4 has an upward protrusion 41 below it. The protrusion 41 includes an inclined surface and a vertical surface. The protrusion 41 can prevent the push rod 1 from moving backward. When the pushing part 32 completes one advance, a tooth 11 will squeeze the inclined surface of the protrusion 41 from one side to the straight surface of the protrusion. The protrusion 41 and the tooth 11 mesh. The tooth 11 on the push rod 1 will be limited by the straight surface of the protrusion 41 of the elastic rubber ring 4, and can only move forward and cannot move backward.

[0031] The grip 21 and the push rod mounting part 22 are preferably integrally formed. The rotating rod 3 includes a pressing part 31 and a pushing part 32 connected to each other. The grip 21 and the push rod mounting part 22 are preferably integrally formed. The hinge shaft 23 that connects the rotating rod 3 and the grip 21 is located at the upper end of the grip 21. The hinge shaft 23 is located at the connection between the pressing part 31 and the pushing part 32 on the rotating rod 3.

[0032] Multiple protruding teeth 11 are evenly spaced on the bottom surface of the push rod 1. The protruding teeth 11 are in the shape of an inverted right-angled trapezoid. The pushing part 32 is made of elastic material and is in the shape of a "V". The pushing part 32 is located between two protruding teeth 11 of the multiple protruding teeth 11.

[0033] In the initial state, the horizontal height of the uppermost end of the pusher 32 is level with the horizontal height of the uppermost end of the tooth 11. The pusher 32 rotates clockwise to push the tooth 11 and make the push rod 1 slide forward. The tooth 11 moves horizontally in a straight line and its horizontal height does not change. The pusher 32 moves in a circle around the hinge axis 23 and its uppermost horizontal height gradually decreases until the rotation limit part 33 contacts the window 25 to restrict the pusher 32 from continuing to rotate. The distance that the push rod 1 advances is equal to the distance between the two nearest teeth 11.

[0034] At this time, rotating the rotating rod 3 counterclockwise will cause the pushing part 32 to rotate counterclockwise. As the horizontal height of the uppermost part of the pushing part 32 slowly increases, it will no longer contact the front tooth 11, but will contact the inclined surface of the rear tooth 11.

[0035] After the pushing part 32 contacts the inclined surface of its rear protrusion 11, it continues to rotate counterclockwise. The pushing part 32 applies an upward force perpendicular to the inclined surface to the protrusion 11, while the inclined surface of the protrusion 11 reacts with a downward force on the pushing part 32. Since the pushing part 32 is made of elastic material and the push rod 1 is restricted from retraction by the protrusion 41, the pushing part 32 undergoes elastic deformation and slides downward on the inclined surface of the protrusion 11 as it rotates counterclockwise. That is, the uppermost end of the pushing part 32 is pressed down, and its horizontal height gradually decreases until the horizontal height of the uppermost end of the pushing part 32 is lower than the bottom surface of the protrusion. At this point, the pushing part 32 disengages from the inclined surface of the protrusion 11, and the pushing part 32 returns to the space between the two protrusions 11. The reaction force applied by the protrusions 11 disappears, and the pushing part 32 elastically returns to its original shape. The horizontal height of the uppermost end of the pushing part 32 is now level with the horizontal height of the uppermost end of the protrusion 11, returning to the initial state. This cycle repeats continuously, continuously advancing the push rod 1.

[0036] like Figure 1 As shown, a torsion spring 24 is fitted onto the hinge shaft 23, with both ends of the torsion spring 24 extending to the lower ends of the grip 21 and the pressing part 31, respectively. After pressing the pressing part 31, the torsion spring 24 provides a driving force for the pressing part 31 and the pushing part 32 to return to their original positions. When the rotating rod 3 is rotated clockwise, the torsion spring 24 is compressed; when the rotation is canceled, the torsion spring 24 expands, providing a driving force for the pressing part 31 and the pushing part 32 to return to their original positions.

[0037] like Figure 3-4 As shown, a window 25 is provided at the connection between the push rod mounting part 22 and the handle 21. The handle 21 is provided with a stationary limiting part 34, and the rotating rod 3 is also provided with a rotation limiting part 33. The pushing part 32 and the rotation limiting part 33 are located inside the window 25. Both the pushing part 32 and the rotation limiting part 33 rotate around the hinge shaft 23, and there is an angle between the pushing part 32 and the rotation limiting part 33. When the rotating rod 3 completes one push clockwise, the rotation limiting part 33 collides with the front side of the window 25, restricting the pushing part 32 from continuing to rotate. When the pushing part 32 rotates counterclockwise between the two gears, the upper end of the pressing part 31 collides with the stationary limiting part 34, restricting the pushing part 32 from continuing to rotate. The rotation trajectory of the rotating rod 3 and the pushing part 32 is fixed by the rotation limiting part 33, the stationary limiting part 34, and the window 25.

[0038] like Figure 1 , 4As shown, an annular boss 26 is provided on the front side of the mounting hole 221, and a groove 42 adapted to the annular boss 26 is provided on the elastic rubber ring 4. The elastic rubber ring 4 is sleeved on the annular boss 26 on the front side of the mounting hole 221 through the groove 42. A connecting cover 5 is provided on the front side of the push rod mounting part 22. The connecting cover 5 is open at both ends and has a partition 51 in the middle. The partition 51 contacts the end of the elastic rubber ring 4 away from the groove 42. The partition 51 has a hole for the push rod 1 to pass through. The end of the connecting cover 5 near the elastic rubber ring 4 is sleeved on the push rod mounting part 22. One end of the elastic rubber ring 4 is fixedly connected to the push rod mounting part 22, and the other end is limited and reinforced by the connecting cover 5. The structure is compact. At the same time, the connecting cover 5 can also be provided with threads or other connecting structures for connecting a container containing gel.

[0039] like Figure 7-9 As shown, a toilet cleaner gel gun includes a gel cylinder 6 and the aforementioned propulsion mechanism. The gel cylinder 6 is connected to a connecting cover 5, and a discharge port 61 is provided at the end of the gel cylinder 6 away from the connecting cover 5. The gel cylinder 6 contains toilet cleaner gel, and the gel cylinder 6 is fixedly connected to the connecting cover 5. A push rod 1 passes through a hole in the partition 51 of the connecting cover 5 and is located inside the gel cylinder 6. When the push rod 1 is pushed, the push rod 1 squeezes the gel in the gel cylinder 6 out of the discharge port 61.

[0040] The discharge port 61 protrudes outward, and a baffle 62 is provided around the discharge port 61. A piston plate 7 is provided inside the gel tube 6, and the piston plate 7 is located at the end of the push rod 1. The piston plate 7 and the inner wall of the gel tube 6 form an inner cavity. The toilet cleaner gel gun also includes a cover 8. The center of the cover 8 is provided with a protrusion 81 that adapts to the discharge port 61. The outer periphery of the cover 8 is provided with an installation groove 82 that adapts to the baffle 62. The cover 8 is also provided with a lever 83 for easy opening. One end of the piston plate 7 connected to the push rod 1 is provided with an insertion groove 71 that adapts to the push rod 1. The end of the piston plate 7 away from the push rod 1 protrudes outward and adapts to the discharge port 61. The outward protrusion of the discharge port 61 facilitates discharge, and the lever 83 on the cover 8 facilitates opening and installing the cover 8. The toilet cleaner gel is filled in the inner cavity. Each time the push rod 1 is pushed forward, the distance in front of the push rod 1 is the same, the distance the piston plate 7 moves forward is also the same, and the amount of gel squeezed out is also the same. The above structure can realize the quantitative squeezing of gel by one hand, which is convenient to operate and has a simple structure. All the above structures can be made of non-metallic materials, resulting in low production costs.

[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected.
