[0040] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.
[0041] like Figure 1-13As shown, the utility model is a large and small drain puller with an air flow channel, including a mounting seat 1, on which is provided a float operating mechanism 2 for linking the float 110 of the drain valve assembly 100 to move accordingly to open or close the drain port 120 of the drain valve assembly 100, and on which is further provided an exhaust control mechanism 3 for controlling whether the inner cavity of the float 110 is connected to or isolated from the outside. When the exhaust control mechanism 3 controls the inner cavity of the float 110 to be connected to the outside, water enters the inner cavity of the float 110 quickly; when the exhaust control mechanism 3 controls the inner cavity of the float 110 to be isolated from the outside, water enters the inner cavity of the float 110 slowly. The utility model controls the connection or isolation of the inner cavity of the float with the outside through the exhaust control mechanism to correspondingly control the speed of water inflow into the inner cavity of the float, thereby controlling the time required for the float to block the drain outlet of the drain valve assembly, and realizing the functions of small-displacement drainage and large-displacement drainage of the drain valve assembly. For this reason, the utility model can realize different water consumption requirements in combination with the adjustment of the float, achieve the effects of flushing cleanliness, energy saving and environmental protection, and at the same time has the characteristics of high practicality, simple and reliable design structure, easy production, easy assembly and low cost.
[0042] like Figure 1-4 As shown in 8-12, for the convenience of operation, the float operation mechanism 2 includes a mounting sleeve 21 connected to the mounting seat 1, an operating shaft 23 rotatably provided in the mounting sleeve 21, an operating lever 24 movably connected to the inner end of the operating shaft 23, and an operating handle 22 movably connected to the outer end of the operating shaft 23, the operating handle 22 drives the operating lever 24 to rotate accordingly through the operating shaft 23, so that the operating lever 24 drives the float 110 to move accordingly to open or close the drain port 120 of the drain valve assembly 100. Fig.13 As shown, the user operates the operating handle 22 to move the operating end downward, and the operating shaft 23 rotates accordingly to operate the operating lever 24 to drive the float 110 to move upward, thereby opening the drain port 120 of the drain valve assembly 100. Figure 2 As shown, the operation is simple and labor-saving; when the force on the operating handle 22 is removed, the float 110 flips downward and resets under the action of its own gravity or the reset torsion spring to reclose the drain port 120 of the drain valve assembly 100. During the reset process of the float 110, the float 110 drives the operating lever 24 to rotate downward and reset through the connecting chain / belt, and at the same time, the operating lever 24 drives the operating handle 22 to automatically rotate upward and reset through the operating shaft 23, as shown in FIG. Figure 1 shown.
[0043] like Figure 1 , 2As shown, the extension direction of the operating lever 24 is opposite to the extension direction of the operating handle 22. The operating lever 24 includes a lever connecting section whose upper end is movably connected to the inner end of the operating shaft 23 and a lever extending section connected to the lower end of the lever connecting section and extending along the axial direction of the operating shaft 23. The lever extending section is connected to the float 110 through a connecting belt.
[0044] like Figure 3-5 As shown, for ease of use, the exhaust control mechanism 3 includes an exhaust valve body 31 disposed on the mounting seat 1, the inner end opening of the exhaust valve body 31 is used to communicate with the inner cavity of the float 110 through an exhaust pipe 32, and a movable sealing block 33 is movably provided on the exhaust valve body 31, and the movable sealing block 33 is provided with an active sealing hole 331 that is aligned with or misaligned with the outer end opening of the exhaust valve body 31. Figure 3 , 8 As shown in FIG. 10, when the exhaust control mechanism 3 is not additionally activated, the movable sealing hole 331 is aligned and connected with the outer opening of the exhaust valve body 31, that is, the inner cavity of the float is connected with the outside through the exhaust control mechanism 3, so that the inner cavity of the float is quickly filled with water, and the float can quickly reclose the drain port of the drain valve assembly 100, realizing the function of small-volume drainage. Fig.11 , 12 As shown, when the movable sealing block 33 moves relative to the exhaust valve body 31 so that the movable sealing hole 331 is misaligned with the outer opening of the exhaust valve body 31, and the outer opening of the exhaust valve body 31 is blocked by the corresponding side wall of the movable sealing block 33, that is, the inner cavity of the float is isolated from the outside by the exhaust control mechanism 3 and is in a sealed state, so that the water inflow into the inner cavity of the float is slow, the float will enter the water more slowly and fall back more slowly, and it will take a long time to close the drain outlet of the drain valve assembly 100 again, thereby realizing the function of large-volume drainage.
[0045] like Figure 3-5 As shown, in order to ensure that the movable sealing block 33 and the exhaust valve body 31 are matched reliably and have a better sealing effect, the exhaust control mechanism 3 also includes a pressing elastic member 34 for driving the movable sealing block 33 to remain against the exhaust valve body 31. Figure 4 , 5 As shown, in order to ensure that the movable sealing block 33 can slide stably and smoothly along the set direction, the exhaust valve body 31 is provided with a mounting groove 311 for the movable sealing block 33 to slide and guide therein, and the front end opening of the exhaust valve body 31 is located inside the mounting groove. Figure 5 As shown, the installation groove 311 has an open upper end and two side walls are arranged in an inverted eight-shaped structure for easy assembly.
[0046] like Figure 3-5As shown, the movable sealing block 33 is provided with a connecting tube 332, and a cross bar 333 for the top pressure elastic member 34 to be sleeved is provided on the movable sealing block 33 and located inside the connecting tube 332. The front end of the driving rod 35 is provided with a driving sleeve 351 for the connecting tube 332 to pass through, and the end wall of the driving sleeve 351 is provided with a sleeve through hole for the free end of the cross bar 333 to pass through and slide and guide, so that the structural linkage between the driving rod 35 and the movable sealing block 33 can be more reliable. In this embodiment, the top pressure elastic member 34 is a top pressure spring or the like.
[0047] like Figure 1-5 As shown, in order to make the structure of the utility model more compact and the overall appearance structure neat and simple, the operating shaft 23 is hollow and has front and rear openings, and the exhaust valve body 31 is located on the inner side of the operating shaft 23, which can also provide a certain protection for the exhaust valve body 31, avoid it from being affected by interference from foreign objects, and extend its service life.
[0048] like Figure 4 , 5 As shown, for convenient operation and labor saving, the exhaust control mechanism 3 also includes an operating button 36 slidably arranged on the operating handle 22 and a driving rod 35 whose middle part is rotatably connected to the operating handle 22. The rotation axis between the middle part of the driving rod 35 and the operating handle 22 is eccentric to the rotation axis between the operating shaft 23 and the operating handle 22. The rear end of the driving rod 35 cooperates with the inner end of the operating button 36, and the front end of the driving rod 35 cooperates with the movable sealing block 33. The pressing elastic member 34 is located between the movable sealing block 33 and the front part of the driving rod 35. In order to improve the resetting effect of the operating button 36, a resetting spring is arranged between the operating button 36 and the operating handle 22, which is not shown in the figure.
[0049] like Figure 4 , 5 As shown in Figures 12, in order to reset reliably and conveniently, a reset blocking structure 4 is provided between the driving rod 35 and the mounting seat 1 for driving the driving rod 35 to automatically rotate and reset when the operating handle 22 rotates and resets. The reset blocking structure 4 includes a reset blocking arm 41 provided on the mounting sleeve 21 and a reset blocking block 42 provided at the front of the driving rod 35, and when the driving rod 35 rotates and resets with the operating handle 22, the reset blocking block 42 cooperates with the reset blocking arm 41 to make the driving rod 35 rotate and reset relative to the operating handle 22.
[0050] like Figure 7As shown, it also includes a water inlet control mechanism 5 for controlling the water inlet amount of the water inlet hole of the float 110, and the water inlet control mechanism 5 includes a water inlet control plate rotatably connected to the float 110, and the water inlet control plate is provided with a control through hole that can be aligned with the water inlet hole or misaligned. In this embodiment, the water inlet control plate is operated to rotate relative to the float 110 to control the through hole to be partially or completely aligned with the water inlet hole, thereby changing the size of the connecting channel between the water inlet hole and the control through hole, and then changing the water inlet amount of the water inlet hole of the float 110. In addition, the water inlet control plate can also be provided with control through holes of different diameters, and the water inlet amount can be changed by simply aligning and connecting the control through hole of the corresponding diameter with the water inlet hole of the float 110, which is convenient for adjustment and use.
[0051] The utility model does not need to change the structure of the original toilet, and only needs to assemble the exhaust control mechanism 3 on the original toilet for use, which is conducive to the rapid upgrading and transformation of the toilet and reduces the transformation cost.
[0052] When using the small-displacement drainage mode, the user only needs to operate the operating handle 22 to flip the operating end downward, and the operating handle 22 drives the operating lever 24 to drive the float 110 to flip upward through the operating shaft 23 to open the drainage port 120 of the drainage valve assembly 100. Figure 2 As shown, at this moment, the movable sealing hole 331 is aligned and connected with the outer opening of the exhaust valve body 31, that is, the inner cavity of the float is kept connected with the outside through the exhaust control mechanism 3, so that water can quickly enter the inner cavity of the float, and the float can quickly reclose the drain port of the drain valve assembly 100.
[0053] like Figure 8 , 9 As shown, the small-displacement drainage mode only requires operating the operating handle 22 to perform corresponding actions, without pressing the operating button 36.
[0054] When using the large-displacement drainage mode, the user presses the operating button 36 to slide downward relative to the operating handle 22, and the lower end of the operating button 36 presses the rear end of the driving rod 35 to make the rear part of the driving rod 35 flip downward relative to the operating handle 22 and the front part of the driving rod 35 flip upward relative to the operating handle 22. At this time, the front end of the driving rod 35 acts on the movable sealing block 33 to move upward relative to the exhaust valve body 31 so that the movable sealing hole 331 is misaligned with the outer end opening of the exhaust valve body 31, and then the outer end opening of the exhaust valve body 31 is blocked by the corresponding side wall of the movable sealing block 33. Fig.11 As shown;
[0055] Then, the operating button 36 acts to turn the operating end of the operating handle 22 downward, and the operating handle 22 drives the operating lever 24 to drive the float 110 to turn upward through the operating shaft 23, thereby opening the drain port 120 of the drain valve assembly 100. Figure 2 shown.
[0056] like Fig.10 , 11 As shown, the large-displacement drainage mode only requires pressing the operating button 36 to slide downward relative to the operating handle 22, and then the operating button 36 presses the operating handle 22 to flip downward.
