[0006] When the water flow in the water outlet channel stops, the opening and closing part is used to drive the valve to rotate under the action of gravity, so that the opening and closing part leaves the air inlet.

[0016] The beneficial effects of the utility model are:

[0017] 1. The utility model arranges a valve in the water outlet channel, drives the valve to close the air inlet through the water flow in the water outlet channel, and reversely drives the valve under the action of the body's gravity to make the opening and closing part leave the air inlet, so that when there is water flow in the water outlet channel, the air inlet can be closed to prevent the water flow from entering or partially entering the deodorizing air duct and causing water ingress and damage to the deodorizing fan.

[0018] 2. The control part is divided into a driving part and a holding part with a certain angle. First, the control part is used to receive the water flow to drive the valve to rotate. As the valve rotates, the angle between the driving part and the water flow gradually decreases, and the effective force-bearing area also decreases. At this time, the holding part rotates to a position with a larger angle with the water flow, and the air inlet is kept closed by the impact of the water flow on the holding part.

[0019] 3. The setting of the drain outlet can reduce the area of ​​the valve that is impacted by the water flow, thereby reducing the impact of the valve on the cross-sectional area of ​​the water outlet channel, maintaining the flow rate of the water flow, and ensuring the flushing effect of the toilet.

[0020] 4. The setting of the abutment portion can limit the movement of the valve, thereby preventing the valve from excessively rotating and failing to close under the dual effects of inertia and gravity. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0030] See also Figures 1 to 6As shown, the utility model discloses a water-powered water-blocking device, comprising a mounting seat 1 arranged in a water tank 100 and a valve 2 arranged on the mounting seat 1, wherein the mounting seat 1 is provided with a deodorizing air duct 11 and a water outlet channel 12, wherein an air inlet 110 opening downward is provided at the end of the deodorizing air duct 11, and the deodorizing air duct 11 is connected to the water outlet channel 12 through the air inlet 110. The valve 2 is rotatably arranged in the water outlet channel 12, and comprises a rotating shaft portion 21, and a control portion 22 and an opening and closing portion 23 respectively arranged on both sides of the rotating shaft portion 21, wherein the control portion 22 is used to control the rotation of the valve 2 under the hydraulic drive of the water flow in the water outlet channel 12, so that the opening and closing portion 23 closes the air inlet 110, thereby preventing the water flow from entering the deodorizing air duct 11; when the water flow in the water outlet channel 12 stops, the opening and closing portion 23 is used to drive the valve 2 to rotate under the action of gravity, so that the opening and closing portion 23 leaves the air inlet 110 and opens the deodorizing air duct 11.

[0031] The utility model sets a valve 2 in the water outlet channel 12, drives the valve 2 to rotate by the water flow in the water outlet channel 12 to close the air inlet 110, and drives the valve 2 to rotate in the opposite direction under the gravity of the valve body 2 so that the opening and closing part 23 leaves the air inlet 110 to open the deodorizing air duct 11. The center of gravity of the valve body 2 is biased to one side of the opening and closing part 23. When the valve body is only subjected to gravity, the valve 2 rotates so that the opening and closing part 23 is located below the control part 22, and the control part 22 is located above. At this time, the opening and closing part 23 is away from the air inlet 110, so as to facilitate deodorization. The water outlet channel 12 is provided with a water inlet 121 at the upper end and a water outlet 122 at the lower end. The water inlet 121 is provided with a drain valve 200 for controlling the opening and closing of the water inlet 122. When the drain valve 200 installed on the water outlet channel 12 is opened to drain the water tank, there is a sufficiently large water flow in the water outlet channel 12, and the water flow falls on the control part 22 to form a downward impact force on the control part 22. The impact force overcomes the gravity of the opening and closing part 23 and drives the valve body to rotate, so that the opening and closing part 23 closes the air inlet 110 to prevent the water flow from entering the deodorizing air duct 11 in whole or in part, causing the deodorizing fan 300 to be damaged by water inflow. The hydraulic drive structure is simple, responsive, and accurately controlled, and the work is more reliable. In addition, when the opening and closing part 23 closes the air inlet 110, the running deodorizing fan 300 will form a certain negative pressure suction force on the opening and closing part 23. This negative pressure suction force and the water flow impact force work together to make the opening and closing part 23 close the air inlet 110 and maintain the state of closing the air inlet 110.

[0032] See also Figures 3 to 5As shown, the control part 22 includes a driving part 221 and a holding part 222 with a certain angle, the driving part 221 is arranged on a side of the holding part 222 away from the rotating shaft part 21, the driving part 221 is used to withstand the impact of the water flow and drive the valve 1 to rotate around the rotating shaft part 21 under the action of the water flow, and the holding part 222 is used to withstand the impact of the water flow and keep the valve 2 in a state of closing the air inlet 100 under the action of the water flow. The driving part 221 is arranged on a side of the holding part 222 away from the rotating shaft part 21, when the driving part 221 is subjected to the impact of the water flow, the impact force exerted by the water flow impact on the driving part 221 forms a longer force arm with the rotating shaft part 21 of the valve, thereby correspondingly increasing the rotational torque, making it easier to drive the valve 2 to rotate, and improving the response speed and reliability of the valve 2. There is a certain angle between the driving part 221 and the holding part 222, so that when the valve 2 opens the air inlet 110, the angle between the driving part 221 and the water flow is larger, and the plane of the driving part 221 for receiving the water flow is close to perpendicular to the direction of the water flow. At this time, the effective force-bearing area of ​​the driving part 221 is larger. As the valve 2 rotates, the opening and closing part 23 rotates in the direction close to the air inlet 110, and the control part 22 rotates in the same direction to reduce the angle between it and the water flow. At this time, the angle between the holding part 222 and the water flow gradually increases, and the driving part 221 is subjected to the impact of the water flow, and the holding part 222 is subjected to the impact of the water flow. The effective force-bearing area of ​​the holding part 222 gradually increases, and the impact force of the water flow acts on the holding part 222 to keep the valve 2 in the state of closing the air inlet 110. Among them, the effective force-bearing area of ​​the utility model refers to the projected area on the plane perpendicular to the direction of the water flow. When the driving part 221 or the holding part 222 is perpendicular to the direction of the water flow, its effective force-bearing area is the largest.

[0033] The edge of the driving part 221 away from the holding part 222 is provided with a flange 28. More specifically, except for the edge connected to the holding part 222, the other edges of the driving part 221 are provided with flanges 28. The driving part 221 in this example is a structure approximately quadrilateral with a notch, so the edges of the three sides of the driving part 221 are provided with flanges 28. When there is water flow in the water outlet channel and the valve 2 rotates to the position of closing the air inlet 110, the flange 28 and the driving part 221 are surrounded to form a water storage tank structure. The water storage tank structure can store a certain amount of water, which can increase the weight of the control part 22 to a certain extent, and help the valve 2 to remain in the position of closing the air inlet 110.

[0034] In this example, the angle between the driving portion 221 and the retaining portion 222 is close to 120°, that is, when the water flow first falls on the driving portion 221, the angle between the direction of the driving portion 221 and the direction of the water flow is close to 60°. This ensures that the driving portion 221 has a large effective force-bearing area, while allowing the water tank formed by the flange 28 and the driving portion 221 to store enough water.

[0035] A water outlet 27 is provided in the middle of the driving part 221, and the water flow in the water outlet channel can pass through the water outlet 27, thereby reducing the area occupied by the driving part 221 in the water outlet channel 12 and reducing its influence on the drainage flow. In addition, when the valve 2 is restored to the state of opening the air inlet 110, the water storage tank structure formed by the flange 28 and the driving part 221 also changes direction accordingly, and the water stored therein can be discharged through the water outlet 27 in time.

[0036] A first transition portion 24 is provided between the retaining portion 222 and the rotating shaft portion 21. The existence of the first transition portion 24 increases the distance between the retaining portion 222 and the rotating shaft portion 21, thereby increasing the force arm when the water flow impacts the retaining portion 222, which is beneficial to further maintain the state of the valve 2 to close the air inlet 110.

[0037] A partition wall 13 extending downward is provided in the water outlet channel 12, the deodorizing air duct 11 is located on one side of the partition wall 13, and the valve 2 is connected to the inner wall of the water outlet channel 12 through a rotating shaft portion 21, and the rotating shaft portion 21 is located on the other side of the partition wall 13. The mounting seat 1 is provided with a mounting shaft, and the rotating shaft portion 21 includes two incomplete annular structures arranged at both ends of the valve 2 in the radial direction, and a blind hole is provided therein, and the blind hole includes a rotating portion 211 for rotationally connecting with the mounting shaft and an assembly portion 212 arranged on one side of the rotating portion 211, and the assembly portion 212 is an opening arranged on one side of the rotating portion 211, and the width of the connection portion between the opening and the rotating portion 211 is smaller than the outer diameter of the mounting shaft, so as to prevent the mounting shaft from escaping from the assembly portion 212, and realize the assembly of the mounting shaft and the rotating portion 211 through the deformation of the incomplete annular structure. The rotating portions 211 of the two blind holes located at both ends of the valve 2 in the radial direction are coaxial, thereby forming the rotating shaft portion 21 of the valve 2.

[0038] A second transition portion 25 is provided between the opening and closing portion 23 and the rotating shaft portion 21, thereby increasing the distance between the rotating shaft portion 21 and the partition wall 13. If there is no second transition portion 25, the distance between the rotating shaft portion 21 and the partition wall 13 is relatively close, which may cause the rotating shaft portion 21 or other parts of the valve 2 to interfere with the partition wall 13 during the rotation of the valve 2, thereby affecting the normal operation of the valve 2. In addition, the second transition portion 25 can also increase the distance between the opening and closing portion 23 and the rotating shaft portion 21, thereby increasing the force arm of the opening and closing portion 23, so that the opening and closing portion 23 is easier to leave the air inlet under the action of gravity.

[0039] Since the valve 2 relies on the gravity of the opening and closing part 23 and the second transition part 25 to drive the valve 2 to return to the position of opening the air inlet 110 after the water flow stops, the valve 2 has a certain inertia during the rotation process. In order to prevent the valve 2 from rotating excessively under the action of inertia and being difficult to recover, or from colliding and hitting the partition wall 13 multiple times under the action of inertia, the control part 22 is provided with an abutment part 26, which is used to abut against the partition wall 13 when the opening and closing part 23 leaves the air inlet 110, thereby forming a rotation limit for the valve 2. The abutment part 26 in this example is arranged on the retaining part 222, and is located on the side of the retaining part 222 facing the partition wall 12.

[0040] The control part 22 and the rotating shaft part 21 are arranged on the same side of the partition wall 13. When the opening and closing part 23 leaves the air inlet 110, the holding part 222 is closer to the partition wall 13 than the driving part 221. Since the control part 22 and the rotating shaft part 21 are arranged on the same side of the partition wall 13, and the opening and closing part 23 rotates in the direction close to the partition wall 13 under the impact of the water flow, the control part 22 including the driving part 221 and the holding part 222 rotates in the direction away from the partition wall 13. In addition, the driving part 221 is subjected to the impact of the water flow before the holding part 222. Therefore, the driving part 221 is arranged at a position farther from the partition wall 13 than the holding part 222, so the driving effect of the water flow impact on the valve 2 can be ensured. The holding part 222 is arranged at a position closer to the partition wall 13, which can reduce the length of the abutting part 26. The abutting part 26 is a protruding rod protruding from the holding part 222. The shorter length can prevent the abutting part 26 from breaking.

[0041] When there is water flow in the water outlet channel 12, the first transition portion 24, the second transition portion 25 and the driving portion 221 are all located in the water outlet channel 12, which will block the water flow. Therefore, the driving portion 221, the first transition portion 24 and the second transition portion are respectively provided with a drain port 27, which can reduce their impact on the water flow and ensure the flow rate of the water outlet channel, thereby ensuring the flushing effect of the toilet.

[0042] In order to enable the valve 2 to smoothly rotate and open the air inlet 110 after the water flow in the water outlet channel 12 stops, the opening and closing part 23 is provided with a weight-increasing structure, which increases the weight of the opening and closing part 23 to drive the valve 2 to move faster and reduce the shaking of the valve 2. The weight-increasing structure in this example is to increase the thickness of the opening and closing part 23. In other embodiments, the weight of the opening and closing part 23 can also be increased by arranging a weighting member on the opening and closing part. The weighting member can be made of a material with a higher density such as a metal block or a rubber block.

[0043] The utility model can be used for deodorizing toilets with water tanks, including any one of sitting toilets, squat toilets and urinals.

[0044] The working process of the utility model is as follows: Figure 3 and Figure 6 As shown, when the drain valve 200 closes the water inlet 121 of the water outlet channel 12, the opening and closing part 23 of the valve 2 moves away from the air inlet 110 under the action of gravity, so that the deodorizing air duct 11 is opened and unobstructed. At this time, if the deodorizing fan is running, the odor in the toilet can be discharged through the air inlet and the deodorizing air duct, thereby achieving the purpose of deodorizing the toilet.

[0045] See also Figure 4 and Figure 6 As shown, when the drain valve 200 opens the water inlet 121 of the water outlet channel 12, the water flows through the water inlet 121, the water outlet channel 12, and the water outlet 122 to flow to the toilet in sequence. The water flow formed in the water outlet channel 12 impacts the driving part 221, driving the valve 2 to rotate in the direction of closing the air inlet 110 (clockwise direction indicated by the arrow in the figure). As the valve 2 rotates, the water flow gradually changes from impacting the driving part 221 to impacting the holding part 222, until the valve 2 rotates to the opening and closing part 23 to close the air inlet 110 and maintain the state of closing the air inlet 110 under the impact of the water flow. In addition, in the process of the valve 2 rotating to make the opening and closing part 23 gradually approach the air inlet 110, the negative pressure suction force generated by the deodorizing fan gradually acts on the opening and closing part 23, further promoting the rotation of the valve 2 and maintaining the opening and closing part 23 in the position of closing the air inlet 110.

[0046] See also Figure 3 and Figure 6 As shown, when the drain valve 200 closes the water inlet 121 of the water outlet channel 12 again or the water flow is reduced to the point where the impact force acting on the control part 22 is less than the gravity of the opening and closing part 22 and the second transition part 25, the valve 2 rotates in the direction away from the air inlet 110 (counterclockwise direction indicated by the arrow in the figure), thereby opening the air inlet 110 again, so that the deodorizing air duct 11 is opened and unobstructed, and the deodorizing fan can perform deodorizing operations.
