Description

Technical Field

[0001] This utility model relates to the field of sanitary ware, and in particular to an automatic toilet cleaner dispenser. Background Technology

[0002] Currently, toilet cleaners on the market generally fall into three main categories: 1. Regular bottled toilet cleaners, which require the user to hold the bottle and pour it into the toilet bowl or spray it around the toilet bowl before manually cleaning with a brush. This requires effort from the user, making it inconvenient and providing a poor user experience; 2. Solid toilet cleaner blocks, which require the user to unpack the block, open the toilet tank lid, and place it in the water. Prolonged soaking in water can cause the blocks to decompose, gradually reducing the effective ingredients and leading to waste. They also have a short shelf life and require manual placement. 1. The toilet tank lid may be dirty, but the lid latch is difficult to open or the fit between the lid and the tank may break due to frequent opening and closing. It is also inconvenient for women to operate, resulting in a poor user experience. 2. It has a metered dispensing dispenser, but before or after use, the lid must be opened and the dispenser must be reached into the water in the tank to replace the liquid. This is also inconvenient and results in a poor user experience. Furthermore, it is difficult to check the remaining liquid level during use, requiring frequent opening of the toilet tank lid to check the remaining liquid level, making it inconvenient to use. Summary of the Invention

[0003] To make toilet cleaning products easier for users to use, and to improve the user experience by eliminating the need to touch the toilet tank lid, and to effectively increase the utilization rate of toilet cleaning products, this utility model provides an automatic toilet cleaning liquid dispenser.

[0004] This utility model is achieved by the following solution:

[0005] An automatic toilet cleaner dispenser includes a main body, which comprises a liquid storage chamber, a container connection end, a water inlet end, and a liquid outlet end. The container connection end is connected to the liquid storage chamber via a liquid inlet hole. The liquid storage chamber is connected to the liquid outlet end via a liquid outlet. The water inlet end and the liquid outlet end are connected via a water inlet channel. The water inlet end has a water inlet that connects to the water inlet channel. The water inlet channel is sealed and separated from the liquid inlet hole. A push rod is provided inside the main body. The push rod can move axially along the liquid storage chamber to an initial position or a discharge position. The push rod is close to the liquid outlet. The end is provided with a separating piston sealing ring, and the liquid storage chamber and the water inlet channel are sealed and separated by the separating piston sealing ring. The end of the push rod near the water inlet end is provided with a water inlet piston sealing ring that can block or open the water inlet as the push rod moves. When water enters the water inlet end, the push rod is pushed from the initial position to the discharge position so that the push rod pushes the liquid in the liquid storage chamber toward the liquid outlet for discharge, so that the discharged liquid mixes with the water output from the water inlet channel. The main body is provided with a reset mechanism that moves the push rod toward the direction of the water inlet end to reset it to the initial position.

[0006] As described above, the automatic toilet cleaner dispenser has a push rod guide groove inside its main body. One end of the push rod guide groove is connected to the water inlet end through the water inlet. The water inlet piston sealing ring can move along the push rod guide groove. The water inlet channel is connected to the other end of the push rod guide groove. When the water inlet piston sealing ring is located in the push rod guide groove, the water inlet piston sealing ring seals and isolates the water inlet and the water inlet channel. The axial length of the push rod guide groove is L. When the push rod is in the initial position, the straight distance between the liquid outlet and the separating piston sealing ring is S, where S is greater than or equal to L. When the push rod moves from the initial position to the liquid discharge position, the movement stroke of the water inlet piston sealing ring is greater than or equal to L, causing the push rod to disengage from the push rod guide groove and connecting the water inlet end to the water inlet channel through the push rod guide groove.

[0007] As described above, the toilet cleaner automatic dispenser has multiple positioning ribs on the side wall of the main body. The multiple positioning ribs are distributed at intervals along the circumference of the main body to radially limit the alignment of the push rod with the push rod guide groove. The water inlet channel includes a water inlet space formed between two adjacent positioning ribs that can communicate with the push rod guide groove.

[0008] As described above, in the automatic toilet cleaner dispenser, the separating piston sealing ring includes a first piston sealing ring and a second piston sealing ring distributed axially along the liquid storage chamber. The first piston sealing ring is fixedly mounted on the push rod, and the second piston sealing ring is disposed between the first piston sealing ring and the liquid outlet end and can move axially relative to the push rod. The push rod is provided with a pressure relief channel penetrating both sides of the second piston sealing ring. When the push rod moves towards the liquid outlet end, the first piston sealing ring approaches and adheres to the second piston sealing ring to drive the second piston sealing ring to move and block one end of the pressure relief channel. When the push rod moves away from the liquid outlet end, the first piston sealing ring first moves away from the second piston sealing ring to form a pressure relief gap communicating with the pressure relief channel, and then the first piston sealing ring moves away from the liquid outlet end along with the push rod.

[0009] As described above, in the automatic toilet cleaner dispenser, the push rod has a connector at one end near the liquid outlet for connecting the first piston sealing ring and the second piston sealing ring. The first piston sealing ring is fixed to the connector, and the second piston sealing ring can move axially relative to the connector. The connector has a stop top located on the side of the second piston sealing ring near the liquid outlet. When the push rod moves away from the liquid outlet, the push rod pulls the second piston sealing ring away from the liquid outlet through the stop top.

[0010] As described above, the automatic toilet cleaner dispenser has multiple pressure relief channels distributed circumferentially on the connector.

[0011] As described above, the automatic toilet cleaner dispenser has multiple water inlet channels distributed circumferentially outside the liquid storage chamber within its main body.

[0012] As described above, the automatic toilet cleaner dispenser has a check valve at the outlet and a reset mechanism including a reset spring.

[0013] As described above, the automatic toilet cleaner dispenser has a drain funnel on the container connection end, the inlet hole is located at the lower end of the drain funnel, and the drain funnel has a paper-cutting protrusion.

[0014] The toilet cleaner dispenser described above also includes a container that is detachably connected to the container connection end.

[0015] Compared with the prior art, this application has the following advantages:

[0016] 1. The biggest advantage of this utility model is its external installation relative to the toilet tank. It can be connected externally to the water pipe supplying water to the toilet tank. For example, it can be externally connected between the inlet pipe at the front of the toilet tank and the angle valve. This utility model connects the inlet pipe to the inlet end and the outlet end to the toilet tank. This utility model works by pressing the toilet tank to drain, which drives the inlet pipe to receive water. The water pressure in the inlet pipe is used as power to move the piston rod in the automatic toilet cleaner dispenser back and forth, achieving automatic dispensing and closing. This automatically pushes the toilet cleaner in the storage chamber to the outlet end. At the same time, the water flowing from the inlet end flows through the inlet channel to the outlet end, thus carrying the toilet cleaner to the toilet tank, thereby achieving... This invention automatically dispenses toilet cleaner into the toilet tank. Users simply need to install the device on the water inlet pipe; no electronic components or solenoid valves are required, effectively saving on manufacturing costs. Changing the toilet cleaner is convenient, as it eliminates the need to disassemble the tank cover, preventing damage to the tank's locking mechanism. Operation is simple, hygienic, and provides a good user experience. Users can easily monitor the remaining toilet cleaner level for timely replacement. Furthermore, the toilet cleaner in the container is not submerged in water for extended periods; dispensing is initiated and stopped by flushing the toilet tank, achieving automatic, metered dispensing, effectively preventing waste and improving the utilization rate of the toilet cleaner product.

[0017] 2. This utility model, by setting a check valve, a push rod with a separating piston sealing ring and a water inlet piston sealing ring, and a water inlet channel that is sealed and separated from the liquid inlet hole and the liquid storage chamber, can effectively prevent toilet cleaner liquid from flowing back into the water inlet pipe and connecting with the domestic water source, thus eliminating the corrosive damage of toilet cleaner liquid to the water inlet pipe and the pollution of domestic water.

[0034] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0035] When ordinal numbers such as "first" and "second" are mentioned in the embodiments of this application, unless they actually express the meaning of order according to the context, they should be understood as being used only for distinction.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" 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 based on the specific circumstances.

[0037] Example: Figures 1 to 15 As shown, the automatic toilet cleaner dispenser of this embodiment includes a main body 1, which includes a liquid storage chamber 11, a container connection end 12, a water inlet end 13, and a liquid outlet end 14. It also includes a container 8 detachably connected to the container connection end 12, which may be made of a translucent material. The container connection end 12 is connected to the liquid storage chamber 11 via a liquid inlet hole 2. The liquid storage chamber 11 is connected to the liquid outlet end 14 via a liquid outlet 3. The water inlet end 13 is connected to the liquid outlet end 14 via a water inlet channel 4. The water inlet end 13 has a water inlet 7 that communicates with the water inlet channel 4. The water inlet channel 4 is sealed and separated from the liquid inlet hole 2. A push rod 5 is provided inside the main body 1. The push rod 5 can move axially along the liquid storage chamber 11 to an initial position or a discharge position. A separating piston sealing ring 52 is provided on the push rod 5 near the liquid outlet end 14. The cavity 11 and the water inlet channel 4 are sealed and separated by a separating piston sealing ring 52. The end of the push rod 5 near the water inlet end 13 is provided with a water inlet piston sealing ring 51 that can block or open the water inlet 7 as the push rod 5 moves. When water enters the water inlet end 13, the push rod 5 is pushed from its initial position to the discharge position, causing the push rod 5 to push the liquid in the storage cavity 11 towards the discharge port 3 for discharge, so that the discharged liquid mixes with the water output from the water inlet channel 4. The main body 1 is provided with a reset mechanism 54 that moves the push rod 5 towards the water inlet end 13 to return it to its initial position. Preferably, the reset mechanism 54 includes a reset spring that can be sleeved on the outer periphery of the push rod 5. The biggest advantage of this embodiment is that it is externally installed relative to the toilet tank 100, and can be externally connected to the water pipe supplying water to the toilet tank 100, such as being externally connected between the front water inlet pipe of the toilet tank 100 and the angle valve 200. Figure 14 and Figure 15As shown, in this embodiment, the inlet end 13 is connected to the inlet pipe, and the outlet end 14 is connected to the toilet tank 100. In this embodiment, pressing the toilet tank 100 to drain water drives the inlet pipe to receive water. The water pressure in the inlet pipe is used as power to reciprocate the piston rod inside the automatic toilet cleaner dispenser, achieving automatic dispensing and shut-off. This automatically pushes the toilet cleaner in the storage chamber 11 to the outlet end 14. Simultaneously, water flowing from the inlet end 13 flows through the inlet channel 4 to the outlet end 14, thus carrying the toilet cleaner to the toilet tank 100, achieving automatic dispensing of toilet cleaner to the toilet tank 100. Therefore, when using this embodiment, the user only needs to install the toilet cleaner dispenser. It can be installed on the water inlet pipe without the need for electronic components or solenoid valves to drive the push rod 5, effectively saving on product manufacturing costs. Replacing the toilet cleaner is convenient, as it eliminates the need to disassemble the toilet tank 100 cover, preventing damage to the tank's locking mechanism. Operation is simple, hygienic, and provides a good user experience. It also allows users to easily observe the remaining toilet cleaner level in container 8 for timely replacement. Furthermore, in this embodiment, the toilet cleaner in container 8 is not submerged in water for extended periods; simply pressing the toilet tank 100 to flush activates and deactivates the dispenser, achieving automatic metered dispensing, effectively preventing waste and improving the utilization rate of the toilet cleaner product.

[0038] Furthermore, the main body 1 is provided with a push rod guide groove 15. One end of the push rod guide groove 15 is connected to the water inlet end 13 through the water inlet 7. The water inlet piston sealing ring 51 can move along the push rod guide groove 15. The water inlet channel 4 is connected to the other end of the push rod guide groove 15. When the water inlet piston sealing ring 51 is located in the push rod guide groove 15, the water inlet piston sealing ring 51 seals and isolates the water inlet 7 from the water inlet channel 4. The axial length of the push rod guide groove 15 is L. When the push rod 5 is in the initial position, the straight distance between the liquid outlet 3 and the separating piston sealing ring 52 is S. S is greater than or equal to L. When the push rod 5 moves from the initial position to the discharge position, the moving stroke of the water inlet piston sealing ring 51 is greater than or equal to L, so that the push rod 5 is disengaged from the push rod guide groove 15, and the water inlet end 13 is connected to the water inlet channel 4 through the push rod guide groove 15. This structure ensures that the push rod 5 moves within the liquid storage chamber 11 with sufficient stroke when water enters the inlet 13, allowing the push rod 5 to disengage from the push rod guide groove 15. This ensures that the inlet end 13 can communicate with the inlet channel 4, so that toilet cleaner can be dispensed into the toilet tank normally in this embodiment.

[0039] Furthermore, the side wall of the main body 1 is provided with a plurality of positioning ribs 9, which are distributed at intervals along the circumference of the main body 1 to radially limit the alignment of the push rod 5 with the push rod guide groove 15. The water inlet channel 4 includes a water inlet space 91 formed between two adjacent positioning ribs 9 that can communicate with the push rod guide groove 15. By setting the positioning ribs 9 to radially limit the push rod 5, when water enters the water inlet end 13, it can effectively prevent the push rod 5 from shaking radially, prevent noise caused by the shaking of the push rod 5, and effectively ensure the relative position stability of the push rod 5 and the push rod guide groove 15, ensuring that when the water inlet end 13 stops entering the water, the push rod 5 can effectively reset and enter the push rod guide groove 15. The main body 1 includes a main body tee 100 and a connecting pipe 102. The liquid storage chamber 11 is located in the main body tee 100, and the push rod guide groove 15 and the positioning ribs 9 are located in the connecting pipe 102.

[0040] Furthermore, the water inlet 13 is provided with a water inlet 7 that can communicate with the water inlet channel 4, and one end of the push rod 5 is provided with a water inlet piston sealing ring 51 that can block or open the water inlet 7 as the push rod 5 moves. When water begins to enter through the water inlet 7 of the water inlet 13, the water flow pushes the water inlet piston sealing ring 51, thereby driving the push rod 5 to move axially along the liquid storage chamber 11. This process does not require an external power supply, complex sensors, or solenoid valves, has a simple structure, low cost, and effectively realizes automated liquid drainage. The other end of the push rod 5 is provided with a separating piston sealing ring 52 for sealing and separating the liquid storage chamber 11 and the water inlet channel 4 to seal the liquid storage chamber 11 during liquid storage. The separating piston sealing ring 52 includes a first piston sealing ring 521 and a second piston sealing ring 522 distributed along the axial direction of the liquid storage chamber 11. The first piston sealing ring 521 is fixedly disposed on the push rod 5, and the second piston sealing ring 522 is disposed between the first piston sealing ring 521 and the liquid outlet end 14 and can move axially relative to the push rod 5. The push rod 5 is provided with a through-hole of the second piston sealing ring 522. When the push rod 5 moves towards the liquid outlet 14, the first piston sealing ring 521 approaches and adheres to the second piston sealing ring 522, causing the second piston sealing ring 522 to move and blocking one end of the pressure relief channel 523. When the push rod 5 moves away from the liquid outlet 14, the first piston sealing ring 521 first moves away from the second piston sealing ring 522 to form a pressure relief gap communicating with the pressure relief channel 523. Then, the first piston sealing ring 521 moves away from the liquid outlet 14 along with the push rod 5. When the push rod 5 moves away from the liquid outlet 14 (i.e., the reset process), the first piston sealing ring 521 first forms a pressure relief gap with the second piston sealing ring 522, allowing the pressure in the liquid storage chamber 11 to be released through the pressure relief channel 523, achieving gas balance on both sides of the second piston sealing ring 522. This design effectively prevents the second piston sealing ring 521 from becoming immobile due to pressure buildup in the liquid reservoir 11, ensuring that the push rod 5 can be reset normally.

[0041] Furthermore, to facilitate the mounting of the first piston sealing ring 521 and the second piston sealing ring 522 on the push rod 5, a connecting member 53 for passing through the first piston sealing ring 521 and the second piston sealing ring 522 is provided at one end of the push rod 5 near the liquid outlet end 14. The first piston sealing ring 521 is fixed to the connecting member 53, and the second piston sealing ring 522 can move axially relative to the connecting member 53. The connecting member 53 is provided with a stop top 531, which is located on the side of the second piston sealing ring 522 near the liquid outlet end 14. When the push rod 5 moves away from the liquid outlet end 14, the push rod 5 pulls the second piston sealing ring 522 away from the liquid outlet end 14 through the stop top 531.

[0042] Furthermore, the connector 53 has multiple pressure relief channels 523 distributed circumferentially. The design of multiple pressure relief channels 523 distributed circumferentially on the connector 53 can ensure efficient pressure relief of the liquid storage chamber 11 after the liquid is drained, and ensure the stable reset of the push rod 5.

[0043] Furthermore, a check valve 6 is provided at the liquid outlet 3. In this embodiment, by setting the check valve 6, as well as the push rod 5 with the separation piston sealing ring 52 and the water inlet piston sealing ring 51, and the water inlet channel 4 structure that is sealed and separated from the liquid inlet hole 2 and the liquid storage chamber 11, the toilet cleaner liquid can be effectively prevented from flowing back into the water inlet pipe, so as to prevent the toilet cleaner liquid from corroding and damaging the water inlet pipe.

[0044] Furthermore, in order to facilitate the precise diversion of the toilet cleaner in container 8 to the liquid storage chamber 11, a drain funnel 121 is provided on the container connection end 12, and the liquid inlet 2 is located at the lower end of the drain funnel 121.

[0045] Furthermore, the drain 121 is provided with a paper-cutting protrusion 122. The paper-cutting protrusion 122 is provided to open the sealing paper on the container 8.

[0046] Furthermore, the main body 1 is provided with a push rod guide groove 15, which is connected to the water inlet 13 through the water inlet 7. The water inlet piston sealing ring 51 is sealed in the push rod guide groove 15 and can move along the push rod guide groove 15. The water inlet channel 4 is connected to one end of the push rod guide groove 15. When the water inlet piston sealing ring 51 is located in the push rod guide groove 15, the water inlet piston sealing ring 51 isolates the water inlet 7 from the water inlet channel 4. By setting the push rod guide groove 15, it is ensured that when water enters the water inlet 13, the water flow in the area of ​​the push rod guide groove 15 can uniquely act on the water inlet piston sealing ring 51, so as to ensure that the water flow effectively pushes the push rod 5 to move and ensures the drainage effect of the push rod 5 in the liquid storage chamber 11.

[0047] The working principle of this embodiment is as follows:

[0048] Toilet cleaner begins to drain: When the user flushes the toilet tank 100, the inlet pipe supplies water to the inlet end 13. The water flow passes through the inlet 7 and automatically pushes the push rod 5 from its initial position toward the outlet 3. As the push rod 5 moves toward the outlet 3, the first piston sealing ring 521 first approaches and adheres to the second piston sealing ring 522, and blocks one end of the pressure relief channel 523. Then, as the push rod 5 continues to move, it drives the second piston sealing ring 522 toward the outlet 3 to the drain position, so that the push rod pushes the liquid in the storage chamber 11 toward the outlet 3 and flows through the check valve 6 to the outlet end 14. When the water flow through the inlet 7 pushes the push rod 5 away from the push rod guide groove 15, the push rod guide groove 15 communicates with the inlet channel 4 and the inlet 7. At this time, the water flows through the inlet channel 4 toward the outlet end 14, thereby bringing the toilet cleaner to the toilet tank 100.

[0049] After the toilet cleaner draining process is complete: When the toilet tank 100 is flushed, the inlet pipe stops supplying water to the inlet end 13. Under the action of the return spring, the push rod 5 moves from the drain position away from the outlet end 14 and closer to the inlet 7 to the initial position, causing the inlet piston sealing ring 51 to move into the push rod guide groove 15 and block the inlet 7. At the same time, during this process, the first piston sealing ring 521 will move away from the second piston sealing ring 522 with the push rod 5 to form a pressure relief gap communicating with the pressure relief channel 523, thus relieving the pressure in the liquid storage chamber 11 and balancing the air on both sides of the second piston sealing ring 522. Then, the push rod 5 pulls the second piston sealing ring 522 together to move and reset through the connector 53. After the push rod 5 resets to the initial position, the toilet cleaner liquid in the container 8 flows into the liquid storage chamber 11 through the liquid inlet hole 2 to replenish it for the next toilet cleaner dispensing operation.

[0050] The above description is one implementation method provided in conjunction with specific content, and does not imply that the specific implementation of this application is limited to these descriptions.
