Description

Technical Field

[0001] This utility model relates to the field of drainage valve technology, and in particular to a single-line double-control drainage valve. Background Technology

[0002] To conserve water resources, existing bathroom drain valves adopt two drainage modes: half-drain and full-drain. In full-drain mode, the drainage time is long and the drainage volume is large, which can drain most of the water in the tank. In half-drain mode, the drainage time is short and the drainage volume is small, which can only drain part of the water in the tank. Therefore, it can save water. Our patent application CN202510021433.3 discloses a single-line dual-control pneumatic drain valve, including a main body shell, valve seat, float, valve plate, and half-row float frame. A pneumatic frame is provided on one side of the main body shell, and a pneumatic structure for lifting the half-row float frame is provided inside the pneumatic frame. A control float is rotatably connected to the half-row float frame. A pedal is provided on the outside of the float. A control groove is provided on the pneumatic frame, and a control rod is provided on the control float. When the control float is not subjected to buoyancy or the control rod is located in the middle of the control groove, the control float abuts against the pedal, and the half-row float frame and the float fall synchronously. When the control float is subjected to buoyancy and the control rod is located at the upper or lower end of the control groove, the control float does not abut against the pedal, and the half-row float frame and the float fall independently. This solution realizes the half-row and full-row discharge of the single-line control drain valve by rotating the control float and whether the control float is in contact with the pedal.

[0003] Existing single-line dual-control pneumatic drain valves achieve half-discharge and full-discharge by adjusting the control rod at different positions in the control slot. The rotation of the control float is controlled by the rising height of the half-discharge float frame driven by the pneumatic structure. While this structure can achieve both half-discharge and full-discharge, in actual use, the control rod only achieves half-discharge within the middle range of the control slot. This leads to unstable drainage volume during half-discharge, affecting the drainage effect. Furthermore, designing the inflation volume for the pneumatic structure to achieve the half-discharge effect is also difficult. Therefore, this application proposes a single-line dual-control drain valve to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a single-line double-control drain valve.

[0005] To solve the above-mentioned technical problems, this utility model includes a main shell, a valve seat, a float, a valve plate, and a half-row float frame. A pneumatic frame is provided on one side of the main shell, and a pneumatic structure for lifting the half-row float frame is provided inside the pneumatic frame. A control float is rotatably connected to the half-row float frame. A pedal is provided on the outside of the float. A control groove is provided on the pneumatic frame. A control rod extending into the control groove is provided on the control float. An elastic stop is provided on the pneumatic frame. A deformation block extending into the control groove is provided on the elastic stop. When the control rod is in low contact with the deformation block, the control float abuts against the pedal, and the half-row float frame and the float fall synchronously. When the control rod overcomes the elastic force of the deformation block and rises to the top of the deformation block, the control float separates from the pedal, and the half-row float frame and the float fall independently.

[0006] Preferably, the deformable block is fixed with a shaft, the shaft is movably connected to the pneumatic frame, the deformable block is connected to an elastic arm, the pneumatic frame is provided with a barrier, and the elastic arm is in low contact with the barrier.

[0007] Preferably, the end of the deformable block extending into the control groove has a conical structure and the tip of the conical structure is arc-shaped.

[0008] Preferably, the control lever is a circular lever.

[0009] Preferably, the elastic arm includes two arms and a U-shaped structure. The two arms are fixed on both sides of the opening of the U-shaped structure. One arm is integrally connected to the shaped edge block, and the other arm is in low contact with the enclosure. When the deformable block rotates, the opening of the U-shaped structure decreases.

[0010] Preferably, the other end of the shaft extends out to the other side of the pneumatic frame, and the extended part of the shaft is fixedly connected to a limit frame. The pneumatic frame is provided with a stop bar, and the limit frame is in low contact with the stop bar.

[0011] Preferably, the pneumatic structure includes an airbag seat, a cylindrical airbag, a top cylinder, and a top plate. The cylindrical airbag is mounted on the airbag seat, and the airbag seat is provided with an inflation hole. The top cylinder is slidably connected to the pneumatic frame, and the cylindrical airbag is located inside the top cylinder. The cylindrical airbag is inflated and lifts the top cylinder. The top plate is located above the top cylinder and is engaged with the side of the half-row float frame.

[0012] The beneficial effects of this utility model are as follows: By providing an elastic stop on the pneumatic frame, the deformation block on the elastic stop can elastically block the control rod on the control float, so that the control rod is in low contact with the deformation block or the control rod overcomes the resistance of the deformation block and rises to the top of the control groove, realizing half-discharge and full-discharge. It can ensure the stability of the half-discharge drainage volume. When inflating, it is only necessary to design two thresholds for the inflation volume of the pneumatic structure, which makes it easy to control the inflation volume of the pneumatic structure. It can quickly raise the control rod on the control float to the top of the control groove, improving the drainage efficiency of the full-discharge. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All directional indicators (such as up, down, left, right, front, back, etc.) in the present utility model are only used to explain the relative positional relationship and movement of each component in a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indicator will also change accordingly.

[0021] like Figures 1-6As shown, this embodiment provides a single-line dual-control drain valve, including a main body shell 1, a valve seat 2, a float 3, a valve plate 4, and a half-row float frame 5. The main body shell 1, valve seat 2, float 3, and valve plate 4 are coaxially arranged. The main body shell 1 is fixedly connected to the valve seat 2. The float 3 is slidably arranged inside the main body shell 1. The lower end of the float 3 is fixedly connected to the valve plate 4. The float 3 is used to lift the valve plate 4, thereby opening the valve port on the valve seat 2. A pneumatic frame 6 is provided on one side of the main body shell 1. The pneumatic frame 6 is provided with a pneumatic structure 7 for lifting the half-row float frame 5. A control float is rotatably connected to the half-row float frame 5. 8. A footboard 9 is provided on the outside of the float 3. A control slot 10 is provided on the pneumatic frame 6. A control rod 11 extending into the control slot 10 is provided on the control float 8. An elastic stop 12 is provided on the pneumatic frame 6. A deformation block 121 extending into the control slot 10 is provided on the elastic stop 12. When the control rod 11 is in low contact with the deformation block 121, the control float 8 abuts against the footboard 9, and the half-row float frame 5 and the float 3 fall synchronously. When the control rod 11 overcomes the elastic force of the deformation block 121 and rises to the top of the deformation block 121, the control float 8 separates from the footboard 9, and the half-row float frame 5 and the float 3 fall independently.

[0022] like Figure 6 As shown, a shaft 122 is fixed to one side of the deformable block 121. The shaft 122 is movably connected to the pneumatic frame 6. An elastic arm 123 is connected to the deformable block 121. A barrier 13 is provided on the pneumatic frame 6. The elastic arm 123 is in low contact with the barrier 13. When the control rod 11 rises, the control rod 11 is in low contact with the deformable block 121. The end of the deformable block 121 near the control groove 10 has an upward rotation tendency under the action of the elastic arm 123, thereby positioning the position of the control rod 11. When the air volume of the pneumatic structure 7 is large, the control rod 11 can make the deformable block 121 rotate at a large angle. The control rod 11 overcomes the elastic force and slides towards the top of the control groove 10, thereby quickly achieving full discharge.

[0023] like Figure 6 As shown, the end of the deformable block 121 that extends into the control groove 10 is a conical structure with an arc-shaped tip, which facilitates the control rod 11 to slide from the tip of the deformable block 121 to the top of the control groove 10. Furthermore, the control rod 11 is a circular rod or the cross-section of the control rod 11 is D-shaped.

[0024] like Figure 6As shown, the elastic arm 123 includes two arms 124 and a U-shaped structure 125. The two arms 124 are fixed on both sides of the opening of the U-shaped structure 125. One arm 124 is integrally connected to the shaped edge block, and the other arm 124 is low-lying with the enclosure 13. When the deformable block 121 rotates, the opening of the U-shaped structure 125 decreases. The design of the U-shaped structure 125 improves the elastic strength of the elastic arm 123. Of course, the elastic arm 123 can also be designed as an arc or linear structure. In order to further enhance the elastic strength, a recurve spring or butterfly spring can be set on the shaft 122 to adjust the elastic resistance of the deformable block 121 by using the elasticity of the spring.

[0025] like Figure 2 , 4 As shown in Figure 6, the other end of the shaft 122 extends out to the other side of the pneumatic frame 6, and the extended part of the shaft 122 is fixedly connected to the limit frame 126. The pneumatic frame 6 is provided with a stop bar 14, and the limit frame 126 is in low contact with the stop bar 14 to limit the reverse rotation of the shaft 122 and prevent the deformation block 121 from rotating clockwise.

[0026] like Figure 5 As shown, the pneumatic structure 7 includes an airbag seat 71, a cylindrical airbag 72, a top cylinder 73, and a top plate 74. The cylindrical airbag 72 is mounted on the airbag seat 71, and the airbag seat 71 is provided with an inflation hole 75. The top cylinder 73 is slidably connected to the pneumatic frame 6, and the cylindrical airbag 72 is located inside the top cylinder 73. The cylindrical airbag 72 inflates and lifts the top cylinder 73. The top plate 74 is located above the top cylinder 73 and is engaged with the side of the half-row float frame 5. The inflation hole 75 is used to connect to an air pump. The air pump has two settings, one of which is used to inflate the cylindrical airbag 72. The cylindrical airbag 72 lifts the top cylinder 73 and the top plate 74, thereby moving the control rod 11 on the control float 8 to the control rod 11. The lifting height of the top plate 74 is determined according to the inflation amount. When the lifting strength is large, the control rod 11 overcomes the resistance of the deformation block 121 and rises to the top of the control rod 11, realizing full displacement.

[0027] It is worth noting that the other structures of the single-line dual-control drain valve not described in this embodiment are consistent with the single-line dual-control pneumatic drain valve disclosed in our patent application number CN202510021433.3, and its specific structure and function will not be described in detail here.

[0028] Its working principle is as follows: By providing an elastic stop 12 on the pneumatic frame 6, the deformation block 121 on the elastic stop 12 can elastically block the control rod 11 on the control float 8, so that the control rod 11 is in low contact with the deformation block 121 or the control rod 11 overcomes the resistance of the deformation block 121 and rises to the top of the control groove 10, realizing half discharge and full discharge. It can ensure the stability of the half discharge drainage volume. When inflating, it is only necessary to design two thresholds for the inflation volume of the pneumatic structure 7, which makes it easy to control the inflation volume of the pneumatic structure 7. It can quickly raise the control rod 11 on the control float 8 to the top of the control groove 10, improving the drainage efficiency of the full discharge.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
