[0033] The present application embodiment discloses a water tank with a liquid level monitoring function, referring to Figure 1 and Figure 2 , including a water tank body 1, on the inner side wall of the water tank body 1 is fixedly installed a monitoring box body 2 in the vertical direction, the side wall of the monitoring box body 2 is penetrated with a plurality of liquid permeable holes 3, a floating ball 4 is placed inside the monitoring box body 2 so as to be raised and lowered, the inner cavity cross section of the monitoring box body 2 is square, the diameter of the floating ball 4 is the same as the side length of the inner cavity cross section of the monitoring box body 2, and the floating ball 4 is in sliding contact with the inner side wall of the monitoring box body 2.
[0034] Reference Figure 2 A mounting box 5 is fixedly installed on the outer side wall of the water tank body 1 in the vertical direction, and the mounting box 5 is arranged adjacent to the monitoring box 2. A plurality of contact switches 6 are fixedly installed at intervals in the vertical direction on the inner side wall of the mounting box 5, and a plurality of signal transmission components are fixedly installed at intervals in the vertical direction on the outer side wall of the mounting box 5. In this embodiment, the signal transmission components are wireless transmitters 20, and each wireless transmitter 20 is electrically connected to a contact switch 6.

[0037] Reference Figure 3 and Figure 4 During the use of the cleaning device, the liquid level inside the water tank body 1 will change, and the float 4 will float on the liquid surface due to its own buoyancy, so that the float 4 will move up and down synchronously inside the monitoring box 2 as the liquid level changes. When the float 4 moves to a preset height as the liquid level changes, the float 4 will collide with the trigger ball 91 at that height, which helps to drive the trigger ball 91 to rotate during the horizontal movement, and then helps to drive the connecting rod 92 and the trigger plate 93 to move synchronously, which helps to make the trigger plate 93 trigger the contact switch 6 during the action. After the contact switch 6 is triggered, it sends a signal to the control system of the cleaning device through the wireless transmitter 20, which helps to realize the alarm function.
[0038] Reference Figure 3 and Figure 4 By setting the diameter of the float 4 and the inner size of the monitoring box 2, it is helpful to limit the movement path of the float 4 in the monitoring box 2, thereby helping to ensure the interference effect between the float 4 and the trigger ball 91, and further helping to ensure the triggering effect of the contact switch 6.
[0039] Reference Figure 2 and Figure 3 By setting up multiple sets of trigger balls 91 and contact switches 6, the float 4 can trigger the contact switches 6 of corresponding heights at multiple different liquid level heights, thereby helping to achieve a multi-level alarm function.
[0040] Reference Figure 5A horizontal reset assembly 10 is also provided inside the mounting seat 7, and the horizontal reset assembly 10 includes a telescopic top support rod 101 and a first reset spring 102. A translation groove 13 is provided on the two opposite groove walls in the horizontal direction of the mounting groove 12. An active block 14 is slidably connected inside the translation groove 13, and a connecting rod 15 is rotatably connected to the active block 14.

The first reset spring 102 is sleeved on the circumference of the telescopic top support rod 101, and one end of the first reset spring 102 abuts against the active block 14, and the other end abuts against the groove wall of the translation groove 13.
[0041] Reference Figure 4 A rotation reset assembly 11 is also provided inside the mounting seat 7, and the rotation reset assembly 11 includes an insertion guide rod 111 and a second reset spring 112. The insertion guide rod 111 is arranged in the clearance opening 16, and an insertion hole 17 for the insertion guide rod 111 to pass through is provided on the connecting rod 92. The second reset spring 112 is sleeved on the circumference of the insertion guide rod 111, and one end of the second reset spring 112 is connected to the connecting rod 92, and the other end is connected to the inner wall of the clearance opening 16.
[0042] Reference Figure 4 and Figure 5 When the float 4 and the trigger ball 91 are no longer in conflict, the first return spring 102 pushes the movable block 14 to move in the translation slot 13 under the action of its own elastic force, so that the movable block 14 drives the trigger ball 91 and the trigger plate 93 to move horizontally to the initial position through the connecting rod 15, thereby helping to reset the position of the trigger ball 91 and the trigger plate 93 in the horizontal direction; at the same time, the second return spring 112 drives the connecting rod 92 to rotate along the interlaced guide rod 111 under the action of its own elastic force, thereby helping to drive the trigger ball 91 and the trigger plate 93 to rotate to the initial position while the connecting rod 92 rotates, thereby helping to reset the position of the trigger ball 91 and the trigger plate 93 in the vertical direction. Under the joint action of the first return spring 102 and the second return spring 112, the trigger ball 91 and the trigger plate 93 are restored to the initial position, thereby facilitating the float 4 to achieve the next conflict with the trigger ball 91, thereby helping to ensure the normal use of the liquid level monitoring function.
[0043] Reference Figure 1A liquid level observation window 18 is fixedly installed on the side wall of the water tank body 1, and a scale line 19 is marked on the liquid level observation window 18 along the height direction of the water tank body 1. During the use of the cleaning device, the user can directly observe the liquid level inside the water tank body 1 through the liquid level observation window 18, thereby helping to improve the convenience of the user to observe the liquid level in the water tank body 1. The setting of the scale line 19 helps to improve the accuracy of the user's observation of the liquid level in the water tank body 1.
[0044] The implementation principle of the embodiment of the present application is as follows: during the use of the cleaning device, the liquid level inside the water tank body 1 will change, and the float 4 will float on the liquid surface due to its own buoyancy, so that the float 4 will move up and down synchronously inside the monitoring box 2 as the liquid level changes. When the float 4 moves to a preset height as the liquid level changes, the float 4 conflicts with the trigger ball 91 at that height, thereby helping to drive the trigger ball 91 to rotate during the horizontal movement, and then helping to drive the connecting rod 92 and the trigger plate 93 to move synchronously, helping the trigger plate 93 to trigger the contact switch 6 during the action. After the contact switch 6 is triggered, it sends a signal to the control system of the cleaning device through the wireless transmitter 20, thereby helping to realize the alarm function.
[0045] The setting of the diameter of the float 4 and the inner size of the monitoring box 2 helps to limit the moving path of the float 4 in the monitoring box 2, thereby helping to ensure the interference effect between the float 4 and the trigger ball 91, and further helping to ensure the triggering effect of the contact switch 6. The setting of multiple groups of trigger balls 91 and contact switches 6 helps to enable the float 4 to trigger the contact switch 6 at the corresponding height under multiple different liquid level heights, thereby helping to achieve a multi-level alarm function.
[0046] When the float 4 and the trigger ball 91 are no longer in conflict, the first return spring 102 pushes the movable block 14 to move in the translation slot 13 under the action of its own elastic force, so that the movable block 14 drives the trigger ball 91 and the trigger plate 93 to move horizontally to the initial position through the connecting rod 15, thereby helping to reset the position of the trigger ball 91 and the trigger plate 93 in the horizontal direction; at the same time, the second return spring 112 drives the connecting rod 92 to rotate along the interlaced guide rod 111 under the action of its own elastic force, thereby helping to drive the trigger ball 91 and the trigger plate 93 to rotate to the initial position while the connecting rod 92 rotates, thereby helping to reset the position of the trigger ball 91 and the trigger plate 93 in the vertical direction. Under the joint action of the first return spring 102 and the second return spring 112, the trigger ball 91 and the trigger plate 93 are restored to the initial position, thereby facilitating the float 4 to achieve the next conflict with the trigger ball 91, thereby helping to ensure the normal use of the liquid level monitoring function.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
