Description

Technical Field

[0001] This utility model relates to the field of sanitary equipment technology, specifically to a toilet tank switch structure. Background Technology

[0002] Toilet tanks typically use a switcher structure to switch flushing modes. Traditional switchers are generally equipped with a float that rises and falls with the water level. As the water level rises or falls, the float changes position and actuates the control mechanism, thus switching the flushing mode. Some floats have a water-filled support at the top, which can hold a certain amount of water, increasing the float's weight and improving stability.

[0003] However, such structures typically employ a vertical motion mode where the pontoon moves linearly up and down along guide rods or columns. The pontoon and load-bearing section are stacked vertically, with the load-bearing section located above the pontoon. Due to space constraints, it is difficult to simultaneously increase the height of the pontoon and the depth of the load-bearing section. If the counterweight cavity is deepened to enhance the initial downforce, the height of the pontoon body is compressed, resulting in a decrease in total buoyancy and a shortened buoyancy stroke. Conversely, if the pontoon size is increased to improve buoyancy performance, sufficient depth cannot be reserved for the counterweight cavity, limiting the performance optimization of the switcher structure. Utility Model Content

[0004] The purpose of this utility model is to provide a toilet tank switch structure, which solves the above-mentioned problems by setting a counterweight and a float on the free end of the lever and placing the counterweight and the float separately at the front and rear.

[0007] As a further optimization of this utility model, the float and the counterweight are arranged perpendicular to the length direction of the switching boom.

[0008] As a further optimization of this utility model, the float and the counterweight are fixedly mounted on the switching boom and can rotate synchronously with the switching boom.

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] This utility model discloses a toilet tank switch structure, including a valve body 1. The valve body 1 has a water distribution chamber 11 and an inlet end 12, a first outlet end 13 and a second outlet end 14 communicating with the water distribution chamber 11. The water distribution chamber 11 is provided with a movable stop block 2. The valve body 1 is also rotatably connected to a switching lifting rod 3. The switching lifting rod 3 is connected to the stop block 2 and can drive the stop block 2 to block the first outlet end 13 or the second outlet end 14. The free end of the switching lifting rod 3 is provided with a float 4 and a counterweight 5 arranged side by side in the horizontal direction.

[0023] like Figures 1 to 4 As shown, a water distribution chamber 11 is provided inside the valve body 1, which guides the water flow to switch the water outlet path. In this embodiment, a water pump for drawing water from the tank is also provided. The inlet end 12 is connected to the outlet end of the water pump, and the first outlet end 13 and the second outlet end 14 correspond to different drainage channels. A stop block 2 is movably arranged inside the water distribution chamber 11, and a switching lever 3 is connected to the stop block 2. When the switching lever 3 rotates, it can drive the stop block 2 to move within the water distribution chamber 11, thereby selectively blocking the first outlet end 13 or the second outlet end 14. The float 4 and the counterweight 5 are arranged side-by-side in the horizontal direction at the free end of the switching lever 3. They do not overlap or substantially do not overlap in the vertical direction, thus avoiding competition for vertical space. The float 4 and the counterweight 5 are arranged side-by-side in the horizontal direction. The counterweight 5 can be installed on the left and right sides of the float 4, or on the front and rear sides of the float 4. The height of the counterweight 5 and the float 4 can be the same or slightly offset. Figure 3 The illustration shows one embodiment in which the pontoon 4 and the counterweight 5 are arranged side by side in the horizontal direction. This side-by-side arrangement can also be other non-vertically stacked horizontal layout forms.

[0024] By placing the float 4 and the counterweight 5 side by side in the horizontal direction at the free end of the switching boom 3, the two avoid occupying each other's height space. This allows for increasing the weight of the counterweight 5 or designing a deeper water storage structure to improve the initial downforce and operational stability. At the same time, it also allows for increasing the size of the float 4 to obtain greater buoyancy, improve the response sensitivity and control accuracy to water level changes, and thus enhance the stability and performance of the switcher.

[0025] In one embodiment, the counterweight 5 and the float 4 are arranged front and rear along the length of the switching boom 3. Specifically, as shown... Figure 3 As shown, the float 4 is installed on the side near the pivot connection end of the switching boom 3, and the counterweight 5 is installed at the rear end away from the pivot. The two do not overlap in the vertical direction, forming a non-stacked horizontal side-by-side arrangement.

[0026] In one embodiment, the float 4 and the counterweight 5 are arranged perpendicular to the length direction of the switching boom 3. Specifically, the float 4 and the counterweight 5 are respectively installed on the left and right sides of the free end of the switching boom 3 (not shown in the figure), and the two are arranged in a transverse direction perpendicular to the axis of the switching boom 3, forming a non-overlapping side-by-side structure.

[0027] Both of these methods can effectively avoid vertical space conflicts and improve the adaptability of the structural layout.

[0028] The float 4 and the counterweight 5 are fixedly mounted on the switching lifting rod 3 and can rotate synchronously with the switching lifting rod 3.

[0029] like Figures 1 to 4 As shown, the float 4 and the counterweight 5 are components of the switching boom 3. During the rotation of the boom, they always maintain a constant relative position and together form a linkage lever system, so that the buoyancy of the float 4 and the gravity of the counterweight 5 can be stably converted into torque acting on the lever system, ensuring that the stop block 2 completes the switching action of the water outlet path at the set water level.

[0030] The counterweight 5 is located on the outer wall of the float 4 away from the switching boom 3, and the counterweight 5 has a counterweight cavity 51 that can accommodate water.

[0031] like Figures 1 to 4 As shown, by placing the counterweight 5 on the outer wall of the float 4 away from the switching lever 3, the counterweight 5 is positioned at the outermost edge of the switching lever 3, extending the lever arm of the counterweight 5 relative to the pivot point. This generates a larger downward torque for the same mass, which helps improve the initial stability of the lever system. Simultaneously, the counterweight 5 is equipped with a counterweight cavity 51 capable of accommodating water. While achieving counterweighting through water, because the counterweight 5 is located at the outermost edge of the switching lever 3, the counterweight cavity 5 can contact the water surface and begin filling earlier during water level rise, further enhancing initial stability.

[0032] The upper surface of the counterweight 5 is a plane, and the counterweight cavity 51 is recessed downward on the upper surface of the counterweight 5. The upper surface of the counterweight 5 is inclined with the front higher than the back, and the angle A between the upper surface of the counterweight 5 and the length direction of the switching lifting rod 3 is an acute angle.

[0033] like Figure 3 As shown, compared to the horizontal setting of the upper surface of the counterweight 5, by setting the upper surface of the counterweight 5 to be higher at the front and lower at the back, forming an acute angle with the length direction of the switching lifting rod 3, the rear end of the upper surface of the counterweight 5 will contact the rising water surface earlier during the water tank filling process. This allows water to enter the counterweight cavity 51 from the rear end of the counterweight 5 earlier, promoting rapid water intake and improving the stability of the initial counterweight; as Figure 4As shown, when the water level drops, the upper end of the counterweight 5 is tilted with the front higher than the back, which can effectively reduce the water flowing out from the front end of the counterweight 5 and ensure the working stability of the counterweight 5.

[0034] The lower part of the float 4 is provided with a float cavity 41 for providing buoyancy. The lower part of the float 4 is inclined forward on the switching boom 3, and the angle B between the extension direction of the main body of the float 4 and the length direction of the switching boom 3 is an acute angle.

[0035] If the float is installed vertically, water can easily flow into the inner cavity when the float rotates with the lever, causing a loss of buoyancy. Figure 3 As shown, by tilting the lower part of the float 4 forward onto the switching boom 3, the arrangement direction of the float 4 is optimized. This allows the float 4 to restrict water flow into the inner cavity 41 of the float when it rotates downward with the switching boom 3, thus improving stability. Simultaneously, the main axis of the float 4 forms an angle with the length direction of the switching boom 3, giving the tilted float 4 a longer actual length. This, in turn, allows the inner cavity 41 to obtain a larger effective volume, providing greater buoyancy and improving reliability.

[0036] The switching boom 3, float 4, and counterweight 5 are integrally molded, which enhances the overall strength while simplifying the assembly process and reducing production costs.

[0037] One end of the switching lever 3 is connected to a rotating shaft 6, and the valve body 1 has a rotating shaft hole 15 for the rotating shaft 6 to pass through. The stop block 2 is located on the side wall of the rotating shaft 6.

[0038] like Figure 2 As shown, one end of the switching lever 3 is fixedly connected to a rotating shaft 6. A rotating shaft hole 15 is provided at a corresponding position on the valve body 1. The rotating shaft 6 passes through the rotating shaft hole 15, allowing the switching lever 3 to swing around the axis of the rotating shaft 6. The stop block 2 is set on the outer peripheral side wall of the rotating shaft 6 and rotates synchronously with the rotating shaft 6. When the switching lever 3 swings due to the change in buoyancy of the float, the rotating shaft 6 rotates accordingly, causing the stop block 2 to deflect within the water distribution chamber 11, thereby selectively blocking the first water outlet 13 or the second water outlet 14, realizing the switching of the flushing mode. The structure is simple.

[0039] The switching lifting rod 3 is provided with reinforcing ribs 31 along its length. In this embodiment, the reinforcing ribs 31 are strip-shaped ribs, which improve the bending strength of the switching lifting rod 3 and prevent deformation.

[0040] The working principle of the toilet tank using this switcher structure is as follows: After the toilet is flushed, the tank begins to fill with water. As the water level gradually rises, the float 4 floats upward due to the buoyancy of the water, causing the free end of the switching lever 3 to rotate upward and move the stop block 2, switching it from blocking the second outlet 14 to blocking the first outlet 13. During the tank's drainage process, the water pump supplies water, causing the water at the inlet 12 to flow to the second outlet 14. Although the water level drops at this time, the pipe pressure exerts pressure on the stop block 2 at the first outlet 13, and the counterweight's force is less than this pipe pressure. This causes the baffle 2 to remain blocking the second outlet 14, thus achieving continuous flushing. When the flushing is complete, the water pump briefly reduces pressure or stops, the pipeline pressure disappears, the float 4 sinks, and the weight of the counterweight 5 causes the free end of the switching lever 3 to rotate downward, driving the baffle 2 to switch from blocking the first outlet 13 to blocking the second outlet 14. Then the water pump works again, and the water flows from the inlet 12 to the first outlet 13 under the action of the water pump, thereby changing the water flow path and realizing the selection of different flushing modes.
