When the siphon effect stops, air enters from the front section of the siphon tube. Since the cross-sectional area of the front section of the siphon tube is larger than the cross-sectional area of the rear section of the siphon tube, the flow rate of the liquid in the front section is smaller than the flow rate of the liquid in the rear section. Part of the liquid in the front section is under the action of gravity. It exchanges positions with air, flows back to the bottom of the cavity, and liquid seals the inlet of the front section of the siphon, that is, blocking the lowest opening in the cavity, so as to isolate the cavity from the outside air and prevent the possible corrosiveness of the toilet cleaning product itself. The gas escapes the cavity and affects sensitive parts in the toilet. This device uses a siphon to drain the toilet cleaning solution in the cavity, and uses the cross-sectional area difference between the front and rear sections to make part of the liquid flow back to the bottom of the cavity to liquid-seal the entrance of the front section of the siphon tube to prevent gas in the cavity from exchanging with the outside world. Protect sensitive parts in the toilet.

In a second aspect, the present invention provides a toilet cleaning product release device installed in a toilet water replenishing pipe, including: a cavity; a water inlet interface connected to the cavity, located on the upper end surface of the cavity, and connected to the toilet water tank.

Example 1

This embodiment provides a toilet cleaning product release device installed in a toilet water replenishing pipe, which is used to add a toilet cleaning product releasing device in the toilet water tank by utilizing the water replenishing process of the toilet water tank. The conventional water replenishing process of the toilet water tank is: the water replenishing pipe in the toilet water tank is connected to the overflow pipe. The water replenishing pipe replenishes water to the overflow pipe after the toilet water tank is flushed. The liquid flowing through the overflow pipe flows to the water accumulation area of the toilet basin. Keep some liquid in the toilet bowl. The toilet cleaning product release device provided in this embodiment is specifically arranged between the water supply pipe and the overflow pipe, so that the liquid entering from the water supply pipe dissolves the toilet cleaning products through the device, and the resulting toilet cleaning solution flows into the accumulation water through the overflow pipe. water area, thereby achieving a more durable and effective toilet cleaning effect in the toilet basin.

As shown in Figure 1, the device includes a cavity 110, and the cavity 110 includes an upper end surface. Preferably, the cavity 110 is a cylindrical wide-mouth container.

A water inlet interface 120 is provided on the upper end surface of the cavity 110 and is connected to the cavity. The water inlet interface 120 is connected to the water supply pipe 10 in the toilet water tank. Preferably, the axis of the water inlet interface 120 is parallel to the axis of the cavity 110, which is beneficial to simplifying the structure of the mold.

A toilet cleaning product 130 is provided in the cavity 110. The toilet cleaning product 130 refers to a solid substance containing active ingredients for cleaning the toilet, and can be in the shape of granules, blocks, etc. Preferably, the toilet cleaning product 130 is a rectangular or cube block material.

The device also includes a siphon pipe, which is a curved pipe and includes a front section 141 of the siphon pipe and a rear section 142 of the siphon pipe. The siphon can be in an inverted "U" shape or in an inverted "凵" shape. In this embodiment, any pipe that can produce a siphon effect on the liquid can be used as the siphon. Therefore, no description of the siphon is used here. Specific restrictions on shape, degree or form of bending/bending. Preferably, as shown in Figure 1, the siphon tube has an inverted "U"-shaped structure.

The front section 141 of the siphon tube is provided in the cavity 110 , specifically close to the inner wall on one side of the cavity 110 . The front section 141 of the siphon tube is provided with an inlet and an outlet, which are respectively located at both ends. The inlet and outlet are connected to form a channel. The inlet of the front section 141 of the siphon pipe is connected with the bottom of the cavity 110 .

The rear section 142 of the siphon tube is located outside the cavity 110 . The rear section 142 of the siphon pipe is provided with an inlet and an outlet, which are respectively located at both ends. The inlet and outlet are connected to form a channel.

The inlet of the rear section 142 of the siphon tube is connected with the outlet of the front section 141 of the siphon tube, and the outlet of the rear section 142 of the siphon tube is connected with the overflow pipe 20 in the toilet tank.

In a specific implementation, as shown in Figures 1 and 2, the upper end surface of the cavity 110 is provided with a water outlet interface 150 connected with the cavity 110, and the outlet of the front section 141 of the siphon pipe is connected with the water outlet interface 150. The water outlet interface 150 is connected with the entrance of the rear section 142 of the siphon tube. As shown in Figures 1 and 2, the water outlet interface 150 and the water inlet interface 120 are located on the same side, so that a larger accommodation space is formed in the cavity 110, and larger toilet cleaning supplies can be placed. Preferably, the axis of the water outlet interface 150 is parallel to the axis of the cavity 110 to simplify mold manufacturing.

As shown in Figure 1, the part where the rear section 142 of the siphon tube is connected to the front section 141 of the siphon tube is the curved part of the pipe, that is, a part of the rear section 142 of the siphon tube needs to be in a curved state. Therefore, in a preferred embodiment, the rear section of the siphon tube 142 is preferably implemented using a soft pipe, which can be directly sleeved on the water outlet interface 150 . The pipe is generally a circular pipe.

As shown in Figure 1, the following conditions are also met between the rear section 142 of the siphon tube and the front section 141 of the siphon tube: the horizontal height of the outlet of the rear section 142 of the siphon tube is lower than the horizontal height of the inlet of the front section 141 of the siphon tube, and there is a height difference Δh between them. The cross-sectional area of 141 is larger than the cross-sectional area of the rear section 142 of the siphon tube.

When the water supply pipe 10 in the toilet tank starts to replenish water, the process of the liquid reaching the overflow pipe 20 along the cavity 110, the front section 141 of the siphon pipe and the rear section 142 of the siphon pipe is as follows:

As shown in Figure 3, liquid enters the cavity 110 from the water inlet interface 120 connected to the water supply pipe 10, and the toilet cleaning supplies 130 located in the cavity 110 begin to dissolve, thereby forming a toilet cleaning solution, and the height of the toilet cleaning solution gradually rises. high, along the front section 141 of the siphon pipe to the rear section 142 of the siphon pipe, and then along the overflow pipe 20 into the toilet basin water accumulation area.

As shown in Figure 4, after the replenishment of the water supply pipe 10 is completed, the rear section 142 of the siphon pipe has been filled with liquid.

Enter the toilet basin water accumulation area through the overflow pipe 20.

Since the overflow pipe 20 does not store liquid, when the liquid level in the cavity 110 is lower than the inlet of the front section 141 of the siphon pipe and no more liquid can flow into the inlet of the front section 141 of the siphon pipe, the siphon effect stops. As shown in Figure 5, at the moment when the siphon effect stops, air enters the front section 141 of the siphon tube. Since the cross-sectional area of the front section 141 of the siphon tube is larger than the cross-sectional area of the rear section 142 of the siphon tube, the liquid flow rate in the front section 141 of the siphon tube is greater than that of the liquid in the rear section 142 of the siphon tube. When the flow rate is slow, the liquid in the front section 141 of the siphon tube exchanges with the air entering the front section 141 of the siphon tube under the action of gravity, interrupting the siphon process, and the liquid in the front section 141 of the siphon tube falls back into the cavity 110 . As shown in Figure 6, the falling liquid can make the liquid level A1 in the cavity 110 higher than the entrance of the front section 141 of the siphon pipe. The liquid seals the entrance of the front section 141 of the siphon pipe, that is, it blocks the lowest opening in the cavity 110, which is equivalent to It isolates the flow of air in the cavity 110 from the outside world, and prevents corrosive gases that may be generated by the toilet cleaning supplies 130 from overflowing the cavity and affecting sensitive components in the toilet.

The partition 240 is arranged longitudinally in the cavity 210 to divide the cavity 210 into two parts with different space sizes. The toilet cleaning supplies 230 located in the cavity 210 are located in the larger space, and the water inlet 220 is also located in the larger space. The side of the larger space facilitates liquid to enter the cavity 210 to dissolve the toilet cleaning products 230 .

The device also includes a siphon pipe, which is a curved pipe and includes a front section 251 of the siphon pipe and a rear section 252 of the siphon pipe.

The front section 251 of the siphon tube is provided in the cavity 210 in a smaller space separated by the partition 240 in the cavity 210 and is close to the inner wall of the cavity 210 . The front section 251 of the siphon pipe is provided with an inlet and an outlet, which are respectively located at its two ends. The inlet and outlet are connected to form a channel. The inlet of the front section 251 of the siphon pipe is connected with the bottom of the cavity 210 .

The horizontal height of the inlet of the front section 251 of the siphon pipe is higher than the horizontal height of the bottom end of the partition plate 240 (the height of the entrance of the front section 252 of the siphon pipe is greater than the height of the notch C).

The rear section 252 of the siphon tube is located outside the cavity 210 . The rear section 252 of the siphon pipe is provided with an inlet and an outlet, which are respectively located at both ends. The inlet and outlet are connected to form a channel.

When the water supply pipe 10 in the toilet tank starts to replenish water, the process of the liquid reaching the overflow pipe 20 along the cavity 210 and the front section 251 and the rear section 252 of the siphon pipe is as follows: the liquid enters the cavity from the water inlet interface 220 connected to the water supply pipe 10 In the larger part of the space 210, the toilet cleaning products 230 located in the same space begin to dissolve, thereby forming a toilet cleaning solution. The height of the toilet cleaning solution gradually increases, along the front section 251 of the siphon pipe to the rear section 252 of the siphon pipe, and along the overflow pipe 20 Enter the toilet basin water area. After the water replenishment pipe 10 is replenished, the rear section 252 of the siphon pipe has been filled with liquid, and the toilet cleaning solution in the cavity 210 continues to flow along the front section 251 of the siphon pipe to the rear section 252 of the siphon pipe under the action of the siphon effect. Since the overflow pipe 20 does not store liquid, when the liquid level in the cavity 210 is lower than the inlet of the front section 251 of the siphon pipe and no more liquid can flow into the inlet of the front section 251 of the siphon pipe, the siphon effect stops. Since the cross-sectional area of the front section 251 of the siphon tube is less than or equal to the cross-sectional area of the rear section 252 of the siphon tube, it can be seen that the liquid flow rate of the front section 251 of the siphon tube is faster than the liquid flow rate of the rear section 252 of the siphon tube or the two are equal. Before the siphon effect stops, the liquid flow rate of the front section 251 of the siphon tube Almost all the liquid in the cavity can flow to the rear section 252 of the siphon tube and enter the overflow pipe 20 under the siphon effect, and the liquid level remaining in the cavity 210 will be slightly lower than the level of the inlet of the front section 251 of the siphon tube, but it is enough to seal the liquid. The partition 240 blocks the lowest opening in the cavity 210, isolates the flow of air in the cavity 210 from the outside world, and prevents the corrosive gases that may be discharged from the toilet cleaning supplies 230 from overflowing the cavity and affecting sensitive people in the toilet. components are affected.
