Description

Technical Field

[0001] This utility model belongs to the technical field of sanitary ware products, specifically relating to a device for releasing chemicals in a water tank and a toilet flushing tank. Background Technology

[0002] Toilet tanks, which integrate water storage and flushing, are often installed and used in conjunction with squat toilets or seated toilets. After use, the toilet needs to be flushed by the water flow in the tank. To improve the flushing effect, toilet cleaner is usually placed in the tank and flushed into the toilet bowl with the water flow to clean the inner walls. However, the toilet cleaner remains dissolved in the tank. When the tank is not used for a period of time, a large amount of toilet cleaner dissolves in the water, resulting in significant waste. This needs further improvement. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for releasing medicine in a water tank and a toilet flushing tank.

[0004] The present invention adopts the following technical solution:

[0005] A device for releasing a chemical agent within a water tank includes a storage tank, a sealing mechanism, and a float.

[0006] A liquid storage tank includes a liquid storage tank body, a liquid storage cavity disposed in the liquid storage tank body for storing medicine, a release cavity disposed in the liquid storage tank body below the liquid storage cavity, and a liquid passage connecting the liquid storage cavity and the release cavity.

[0007] A sealing mechanism is installed in the liquid passage, which can seal the upper end of the liquid passage to allow the agent in the liquid passage to enter the release chamber or seal the lower end of the liquid passage to allow the agent in the storage chamber to enter the liquid passage;

[0008] The float is oscillatingly positioned in the release chamber. The sealing mechanism can move upward under the action of the float to connect the liquid passage with the liquid storage chamber or move downward to connect the liquid passage with the release chamber.

[0009] Furthermore, the float includes a float body and a water storage chamber and a buoyancy chamber arranged vertically opposite each other on the float body. When the water level in the tank rises, the water in the buoyancy chamber causes the side of the float body near the sealing mechanism to swing downward, driving the sealing mechanism to move downward, connecting the liquid channel and the release chamber. When the water level in the tank drops, the water in the water storage chamber causes the side of the float body near the sealing mechanism to swing upward, driving the sealing mechanism to move upward, connecting the liquid channel and the liquid storage chamber.

[0010] Furthermore, it also includes a swing arm disposed in the release chamber to connect the liquid storage tank body and the float. The first end of the swing arm is movably connected to the float, the second end is movably connected to the lower end of the sealing mechanism, and the middle part is movably connected to the opposite liquid storage tank body.

[0011] Furthermore, the liquid storage tank also includes a connecting seat disposed in the release chamber and connected to the liquid storage tank body, and the middle part of the swing arm is movably connected to the connecting seat via a rotating shaft.

[0012] Furthermore, the float also includes a clearance area disposed on the float body opposite to the sealing mechanism, and the water storage cavity is disposed on both sides of the float body opposite to the clearance area.

[0013] Furthermore, the sealing mechanism includes an upper sealing element and a lower sealing element arranged sequentially from top to bottom. The upper sealing element includes an upper sealing ring that can abut against the upper end of the liquid passage, and the lower sealing element includes a lower sealing ring that can abut against the lower end of the liquid passage.

[0014] Furthermore, the upper sealing element includes an upper sealing seat that extends upward into the liquid storage chamber in the liquid passage and an upper mounting groove that is disposed on the outer periphery of the upper end of the upper sealing seat for installing an upper sealing ring; the lower sealing element includes a lower sealing seat that extends downward into the release chamber in the liquid passage and a lower mounting groove that is disposed on the outer periphery of the lower end of the lower sealing seat for installing a lower sealing ring.

[0015] Furthermore, the upper sealing seat and the lower sealing seat are detachably connected, the lower sealing seat is provided with an elastic buckle at the top, and the upper sealing seat is formed with a connecting groove at the bottom for the elastic buckle to be inserted.

[0016] A toilet flushing tank includes a tank body, characterized in that it further includes a device for releasing an agent as described in any of the above claims, disposed within the tank body.

[0017] As can be seen from the above description of this utility model, compared with the prior art, the beneficial effects of this utility model are as follows: This application, by limiting the cooperation between the float and the sealing mechanism, controls the swing direction of the float by the rise and fall of the water level in the tank. When the water level in the tank rises, the sealing mechanism can move downward under the action of the float to connect the liquid passage with the release chamber, allowing the agent in the liquid passage to flow into the tank. After the water level rises to the required level, water will enter the liquid passage to ensure that the agent is fully mixed. When the water level in the tank falls, the sealing mechanism can move upward under the action of the float to connect the liquid passage with the storage chamber and block the connection between the liquid passage and the release chamber, allowing the agent in the storage chamber to enter the liquid passage for temporary storage. The overall device is simple, can achieve full mixing of the agent, and can also achieve rapid sealing of the liquid passage by the sealing mechanism to ensure the effective use of the agent.

Detailed Implementation

[0031] The present invention will be further described below through specific embodiments.

[0032] Reference Figure 1As shown, a toilet flushing tank includes a tank body 1 and an inlet valve 2, a flushing valve 3, and a device for releasing chemicals disposed in the tank body 1.

[0033] Reference Figures 2 to 4 As shown, the device 4 for releasing the agent includes a liquid storage tank 5, a sealing mechanism 6, a float 7, and a swing arm 8.

[0034] Reference Figures 5 to 8 As shown, the liquid storage tank 5 includes a liquid storage tank body 51, a liquid storage cavity 52 disposed in the liquid storage tank body 51 for storing the medicine, a release cavity 53 disposed in the liquid storage tank body 51 below the liquid storage cavity 52, a liquid passage 54 connecting the liquid storage cavity 52 and the release cavity 53, and a connecting seat 55 disposed in the release cavity 53 and connected to the liquid storage tank body 51. The liquid storage cavity 52 extends downward from the top of the liquid storage tank body 51, and the release cavity 53 extends upward from the bottom of the liquid storage tank body 51.

[0035] A sealing mechanism 6 is installed in the liquid passage 54. It can seal the upper end of the liquid passage 54 to allow the agent in the liquid passage 54 to enter the release chamber 53, or seal the lower end of the liquid passage 54 to allow the agent in the storage chamber 52 to enter the liquid passage 54. Specifically, the sealing mechanism 6 includes an upper sealing member 61 and a lower sealing member 62 arranged vertically. The upper sealing member 61 can seal the upper end of the liquid passage 54 to block the agent from entering the liquid passage 54, allowing the agent in the liquid passage 54 to enter the release chamber 53 and then enter the water tank body 1 to mix evenly with the water. The lower sealing member 62 can seal the lower end of the liquid passage 54 to block the communication between the liquid passage 54 and the release chamber 53, allowing the storage chamber 52 to communicate with the liquid passage 54. At this time, the agent in the storage chamber 52 can enter the liquid passage 54.

[0036] The upper sealing element 61 includes an upper sealing seat 611 that extends upward from the liquid passage 54 to the liquid storage chamber 52, an upper mounting groove 612 that is disposed on the outer periphery of the upper end of the upper sealing seat 611, and an upper sealing ring 613 that is sleeved in the upper mounting groove 612 and can abut against the upper end of the liquid passage 54.

[0037] The lower seal 62 includes a lower sealing seat 621 that extends downward from the liquid passage 54 to the release chamber 53, a lower mounting groove 622 that is disposed on the outer periphery of the lower end of the lower sealing seat 621, and a lower sealing ring 623 that is sleeved in the lower mounting groove 622 and can abut against the lower end of the liquid passage 54. Specifically, the lower sealing seat 621 is detachably connected to the upper sealing seat 611. The lower sealing seat 621 is provided with an elastic buckle 625 at the top, and the upper sealing seat 611 is provided with a connecting groove 614 at the bottom for the elastic buckle 625 to be inserted.

[0038] The float 7 is pivotally mounted in the release chamber 53. The sealing mechanism 6 can move upward under the action of the float 7 to connect the liquid passage 54 with the liquid storage chamber 52, or move downward to connect the liquid passage 54 with the release chamber 53. The float 71 includes a float body 71 and a water storage chamber 72 and a buoyancy chamber 73 arranged vertically opposite each other on the float body 71. The water storage chamber 72 and the buoyancy chamber 73 are located on the side of the float body 71 away from the sealing mechanism 6, and the buoyancy chamber 73 extends upward from the bottom of the float body 71, connecting with the water tank body 1. The parts are connected; when the water level in the tank rises, the water entering the buoyancy chamber 73 causes the float body 71 near the sealing mechanism 6 to swing downward, driving the sealing mechanism 6 to move downward, connecting the liquid passage 54 and the release chamber 53, and blocking the liquid passage 54 and the storage chamber 52; when the water level in the tank drops, the water in the storage chamber 72 causes the float body 71 near the sealing mechanism 6 to swing upward, driving the sealing mechanism 6 to move upward, connecting the liquid passage 54 and the storage chamber 52, and blocking the liquid passage 54 and the release chamber 53.

[0039] A swing arm 8, disposed in the release chamber 53, connects the liquid storage tank body 51 and the float body 71. The first end of the swing arm 8, away from the sealing mechanism 6, is movably connected to the float body 71; the second end, closer to the sealing mechanism 6, is movably connected to the lower end of the lower sealing seat 621; and the middle part is movably connected to the opposite connecting seat 55. A rotating seat 75, movably connected to the first end of the swing arm 8, is provided in the water storage chamber 72. Specifically, the middle part of the swing arm 8 is movably connected to the connecting seat 55 via a rotating shaft 9, and both ends of the rotating shaft 9 are respectively connected to the float body 71. The connection allows the float body 71 to be movably connected to the liquid storage tank body 51 so that it can move together with the swing arm 8. Correspondingly, the float 7 is also provided with a clearance area 74 opposite to the sealing mechanism 6. The water storage cavity 72 is disposed on both sides of the float body 71 opposite to the clearance area 74. The clearance area 74 provides a movement area for the second end of the swing arm 8 to swing downward. Furthermore, the second end of the swing arm 8 forms a rotating groove 81 that is connected to the lower sealing seat 621. The lower end of the lower sealing seat 621 is rotatably disposed in the rotating groove 81 via a pin shaft 624.

[0040] The working principle of this application is as follows:

[0041] Reference Figures 11 to 12As shown, when the water level in the tank gradually rises, the side of the float body 71 away from the sealing mechanism 6 gradually floats up. The swing arm 8, using the connecting seat 55 as a fulcrum, drives the side of the float body 71 close to the sealing mechanism 6 to gradually swing downward, converting buoyancy into downward pressure on the sealing mechanism 6. This causes the sealing mechanism 6 to move downward, connecting the liquid passage 54 and the release chamber 53, and simultaneously cutting off the connection between the storage chamber 52 and the liquid passage 54. At this time, some of the agent in the liquid passage 54 will enter the water tank along the lower end of the liquid passage 54. As the water in the tank continues to rise until it submerges the liquid passage 54, the remaining agent in the liquid passage 54 will be completely diluted into the water in the tank. At the same time, water will enter the storage chamber 72.

[0042] Reference Figures 9 to 10 As shown, when the water level in the tank drops, the side of the float body 71 away from the sealing mechanism 6 gradually swings down. The swing arm 8, with the connecting seat 55 as the fulcrum, drives the side of the float body 71 close to the sealing mechanism 6 to swing upward, converting the gravity generated by the water in the water storage chamber 72 into the upper pressure of the sealing mechanism 6, causing the sealing mechanism 6 to move upward and connect the liquid passage 54 with the liquid storage chamber 52, while simultaneously isolating the liquid passage 54 from the release chamber 53. At this time, the agent in the liquid storage chamber 52 gradually flows into the liquid passage 54 through the upper end of the liquid passage 54.

[0043] This application controls the swing direction of the float 7 by cooperating with the sealing mechanism 6 and adjusting the water level in the tank according to the rise and fall of the water level. When the water level in the tank rises, the sealing mechanism 6 can move downward under the action of the float 7 to connect the liquid passage 54 with the release chamber 53, allowing the agent in the liquid passage 54 to flow into the tank. After the water level rises to the required level, water will enter the liquid passage 54 to ensure thorough mixing of the agent. When the water level in the tank falls, the sealing mechanism 6 can move upward under the action of the float 7 to connect the liquid passage 54 with the storage chamber 52 and block the connection between the liquid passage 54 and the release chamber 53, allowing the agent in the storage chamber 52 to enter the liquid passage 54 for temporary storage. The float 7 is equipped with... The device comprises an upper and lower opposing water storage chamber 72 and a buoyancy chamber 73. The buoyancy chamber 73 provides buoyancy when the water level rises, while the water storage chamber 72 provides gravity when the water level falls. No additional structures such as springs or counterweights are required. Furthermore, the rapid conversion between buoyancy and gravity during water level drops enables quick sealing of the upper or lower end of the liquid passage 54. Additionally, the float 7 is oscillatingly positioned in the release chamber 53 via a swing arm 8 and a connecting seat 55. The swing arm 8 and connecting seat 55 work in a lever-like manner, amplifying the sealing force and making the sealing mechanism 6 more effective. In summary, the overall device of this application is simple, achieves thorough mixing of the reagent, and enables the sealing mechanism 6 to quickly seal the liquid passage 54, ensuring the effective use of the reagent.
