Structure for continuously variable adjustment of resistance in an improved water resistance tank

Abstract

This application discloses an improved stepless resistance adjustment structure for a water resistance tank, comprising: a water tank body, wherein a water storage tank is provided inside to divide the inner space of the water tank body into a water storage chamber and a resistance chamber, the water storage tank is provided with a water inlet channel at a high position, the bottom of the water storage tank protrudes upward to form an overflow wall that penetrates into the water outlet chamber, the inner side of the overflow wall forms an overflow channel that connects to the resistance chamber, and the portion of the overflow wall sidewall located in the water outlet chamber is provided with an overflow port; an adjustment component, rotatably disposed in the water storage chamber and located on one side of the overflow wall, including a shielding structure for shielding the overflow port, the top of the shielding structure and the overflow port forming an overflow port for the liquid in the water storage chamber to flow out.

Claims

1. An improved water resistance box resistance stepless adjustment structure, comprising: A water tank body includes a water storage tank that divides the inner space of the water tank body into a water storage cavity located inside the water storage tank and a resistance cavity located between the water storage tank and the water tank body. The side wall of the water storage tank has a water inlet channel at a high position. The bottom of the water storage tank protrudes upward to form an overflow wall that penetrates into an outlet cavity. The inner side of the overflow wall forms an overflow channel that connects to the resistance cavity. An overflow port is provided through the side wall of the overflow wall located in the outlet cavity. An adjusting member is rotatably disposed in the water storage cavity and located on one side of the overflow wall. It includes a shielding structure for shielding the overflow port. An overflow port for liquid to flow out of the water storage cavity is formed between the top of the shielding structure and the overflow port. The shielding structure is configured such that the height of the lowest position of the overflow port changes linearly with the rotation of its body.

2. As in request item 1, the improved water resistance tank resistance stepless adjustment structure, wherein, The overflow wall includes a pair of relatively parallel sidewalls and a U-shaped wall connecting the two sidewalls on the same side, with the overflow outlet formed on the side of the two sidewalls away from the U-shaped wall.

3. As in request item 2, the improved water resistance tank resistance stepless adjustment structure, wherein, The center of the U-shaped wall is positioned opposite the center of the water storage tank to form a through-axis channel running vertically through the tank.

4. As in request item 2, the improved water resistance tank resistance stepless adjustment structure, wherein, The top of the U-shaped wall and the side wall extends to a position flush with the upper edge of the water storage tank.

5. The improved water resistance tank resistance stepless adjustment structure as described in request item 2, wherein, The adjusting component also includes a connecting shaft and a knob located at the top of the connecting shaft to control the rotation of the connecting shaft, and the shielding structure is arranged around the outer periphery of the connecting shaft.

6. As in request item 5, the improved water resistance tank resistance stepless adjustment structure, wherein, The shielding structure includes a fan-shaped base plate and a shielding plate extending upward around the circular perimeter of the base plate. The top of the shielding plate is a spiral shape with increasing height, so that the shielding plate at different positions and the overflow port form an overflow edge with different height positions.

7. The improved water resistance tank resistance stepless adjustment structure as described in request item 6, wherein, The highest point of the shield is provided with a horizontal section of consistent height so that the shield opposite the horizontal section forms an initial end with the largest overlapping shielding area with the overflow outlet.

8. As in request item 6, the improved water resistance tank resistance stepless adjustment structure, wherein, A connecting piece is provided between the baffle and the connecting shaft, and the highest position of any of the connecting pieces is consistent with the top of the baffle.

9. The improved water resistance tank resistance stepless adjustment structure as described in request item 6, wherein, A rotating protrusion is provided at the bottom of the water storage tank and on one side of the overflow port. The lower end of the connecting shaft is provided with a rotating hole that mates with the rotating protrusion.

10. The improved water resistance tank resistance stepless adjustment structure as described in request item 6, wherein, The base plate is D-shaped with a central angle of 180°.
