As long as the floating block 9 rises and falls reciprocally under the action of buoyancy and gravity, the sealing plug is caused to reciprocate in the transit portion 5, so that the toilet cleaning liquid is enabled to enter the water tank or prevented from entering the water tank.

Based on the same concept as the above embodiment, this embodiment also proposes that the hinge point of the transmission rod 8 with the body 1 is close to the first end as shown in fig. 2.

In this embodiment, in order to amplify the power provided by the floating block 9 to the transmission rod 8, the hinge point between the transmission rod 8 and the body 1 is disposed at a position close to the first end, that is, the distance from the hinge point to the first end is greater than the distance from the hinge point to the second end. The lever principle mode is adopted, so that the ejector rod 7 can be subjected to a better force effect, the plugging and opening effects of the closed plug 2 are more stable, and liquid leakage is avoided.

Based on the same concept as the above embodiment, as shown in fig. 1, this embodiment further proposes that the ejector rod 7 is provided with a through hole 10, and the end of the transmission rod 8 penetrates into the through hole 10.

In this embodiment, since there is a relative movement at the connection between the ejector rod 7 and the driving rod 8 during the ascending and descending process of the floating block 9, in order to avoid interference between the ejector rod 7 and the driving rod 8, the through hole 10 is formed in the ejector rod 7, the end of the driving rod 8 can penetrate into the through hole 10, and the end of the driving rod 8 contacts the inner wall of the through hole 10, so that a certain interference exists between the ejector rod 7 and the driving rod 8, and the resistance between the driving rod 8 and the ejector rod 7 is reduced.

In this embodiment, for convenience in manufacturing, the through hole 10 is set to be in a square hole form, after the first end portion of the transmission rod 8 penetrates into the through hole 10, the outer wall of the first end portion of the transmission rod 8 contacts with the inner top wall of the through hole 10, and this contact manner improves the stability of contact, and avoids separation between the ejector rod 7 and the transmission rod 8 during movement. When the floating block descends, the first end of the transmission rod is contacted with the bottom wall of the through hole.

Based on the same concept as the above embodiment, this embodiment also proposes that the float 9 has a cavity, as shown in fig. 3.

In this embodiment, in order to increase the buoyancy force applied to the floating block 9, a cavity is provided inside the floating block 9, and the floating block 9 in a hollow state is subjected to better buoyancy force.

Based on the same concept as the above embodiment, this embodiment also proposes that the second end is hinged with the float 9 and that the hinge point is located at the top of the float 9, as shown in fig. 2.

In this embodiment, since a certain degree of relative movement occurs between the float 9 and the transmission rod 8 during the ascending and descending of the float 9, in order to avoid interference between the transmission rod 8 and the float 9, the second end of the transmission rod 8 and the float 9 are provided in a hinged manner. This hinge point is also provided on top of the float 9 in order not to influence the sinking and floating of the float 9 in the water.

Based on the same concept as the above embodiment, as shown in fig. 1, the present embodiment further proposes that the body 1 includes an upper cover 11 and a lower shell 12, the upper cover 11 is detachably disposed on the lower shell 12, the liquid inlet portion 4 is disposed on the upper cover 11, and the middle portion 5 and the liquid outlet portion 6 are disposed on the lower shell 12.

Because the closing plug 2 is disposed in the transfer portion 5, and the closing plug 2 is further required to plug the communication portion between the liquid inlet portion 4 and the transfer portion 5, the closing plug 2 must be larger than the liquid inlet portion 4, and in order to mount the closing plug 2 to the transfer portion 5, the detachable connection manner can be realized.

Based on the same concept as the above embodiment, as shown in fig. 1 to 5, the present embodiment further proposes that the upper cover 11 is provided with a first accommodating cavity, the lower shell 12 is provided with a protrusion, the middle part 5 is provided on the protrusion, the protrusion penetrates into the first accommodating cavity and forms a second accommodating cavity, the closing plug 2 is located in the second accommodating cavity, and the middle part 5 includes the second accommodating cavity.

In this embodiment, set up first chamber that holds on upper cover 11, set up the arch on inferior valve 12, when upper cover 11 is connected with inferior valve 12, the arch can penetrate first chamber that holds in, at this moment, as long as set up the sealing washer between bellied outer wall and the inner wall of first chamber that holds, just can realize the leakproofness of the lateral wall of liquid feeding passageway. When the protrusion penetrates into the first accommodating cavity, a second accommodating cavity is formed, the sealing plug is positioned in the second accommodating cavity, and the second accommodating cavity is only a part of the transfer part 5.

Based on the same concept as the above embodiment, as shown in fig. 1 to 5, the present embodiment also proposes that the size of the transit portion 5 and the size of the liquid outlet portion 6 are both larger than the size of the liquid inlet portion 4.

In this embodiment, since the closing plug 2 is located at the transit portion 5 and bidirectional plugging is achieved by moving itself, the size of the transit portion 5 is set larger than that of the liquid inlet portion 4 and the liquid outlet portion 6.

The dimensions of the intermediate portion 5 are for the portion through which the toilet cleaning liquid flows, and are not the dimensions of other unimportant portions. Similarly, the concept of the size of the liquid inlet portion 4 and the size of the liquid outlet portion 6 are the same as the concept of the size of the intermediate portion 5.

Based on the same concept as the above embodiment, as shown in fig. 2, this embodiment also proposes that a sinking block is connected below the floating block, where the sinking block may be a solid block or a hollow block, and when the sinking block is a hollow block, a weight needs to be added into the sinking block. The sinking block is used for ensuring that the whole device is positioned in the water tank and cannot float upwards along with the water surface.

The bidirectional closing switch for the water tank provided by the utility model can be also suitable for scenes or devices with the water tank and needing to add liquid into the water tank.
