Description

Technical Field

[0001] The invention relates to the technical field of intelligent bathrooms, in particular to a waterway control mechanism. Background Art

[0002] With the rapid economic development, people's income has increased, and consumers have paid more and more attention to the quality of life. Smart sanitary ware has entered more and more families. As a typical representative, smart toilets are increasingly popular in places such as homes and high-end hotels due to their advantages of monitoring comfort, cleanliness and hygiene. The most common functions of smart toilets are buttocks cleaning, women's lower body cleaning, and water volume adjustment. Switching between these functions is like turning the switch handle to the corresponding gear. If the handle is too long, the handle will hit the toilet cover shell or be restricted by the toilet cover shell and cannot be operated. If the handle is too short, the switching torque is too large and the operation is laborious; it is like turning the knob to the corresponding gear. Even if there are textures on the knob, it is still easy to slip and inconvenient to operate. Summary of the invention

[0063] refer to Figures 9 to 11 and Fig.23 As shown, the water inlet and water stop principle of the buttocks washing machine is as follows: by pressing the first button 21, the control rod 122 for controlling the buttocks washing machine is driven to move forward through the buttocks washing connecting piece 23, thereby driving the switching rod 121 of the buttocks washing machine to rotate; when the first button 21 is released, the switching rod 121 of the buttocks washing machine retreats under the elastic force of the control spring 123 of the buttocks washing machine, and the retreat stroke is greater than the forward stroke, and the protruding block 1211 of the buttocks washing machine pushes the limiting rib 1411 of the buttocks washing machine to retreat, and the compression spring force of the control spring 123 of the buttocks washing machine is greater than the return spring The compression spring force of 142 drives the back pressure rod 141 to overcome the action force of the reset spring 142 and retreat, and the back pressure pad 143 leaves the back pressure hole 321; at the same time, pressing the first button 21 pushes the hip wash connecting piece 23, and the pushing block 234 on the hip wash connecting piece 23 pushes the first contact 611 on the rocker rod 61, and the push rod 62 moves forward under the drive of the rocker rod 61, and the pull rod 63 is in the distal state. At this time, the spray gun 64 is in the hip wash position, thereby realizing the hip wash water intake. Press the first button 21 again, and the control rod 122 for controlling the buttocks washing will move forward through the buttocks washing connecting piece 23, driving the switching rod 121 of the buttocks washing to rotate; when the first button 21 is released, the switching rod 121 of the buttocks washing will retreat under the elastic force of the control spring 123 of the buttocks washing. Due to the limitation of the rib 1111, the retreat stroke is smaller than the forward stroke. At this time, the protruding block 1211 of the buttocks washing does not contact the limiting rib 1411, and the back pressure rod 141 drives the back pressure pad 143 to press the back pressure hole 321 under the action of the reset spring 142, and the incoming water flows into the hole groove of the needle valve between the rubber pad 33 and the upper cover 32. Since the back pressure hole 321 is closed, the rubber pad 33 presses the water inlet on the water-passing body 31 under the action of water pressure, thereby achieving water stopping of the buttocks washing.

[0064] refer to Figure 12 to Figure 14 and Fig.24As shown, the water inlet and water stop principle of the women's wash basin is as follows: the second button 22 is pressed to push the control rod 122 for controlling the women's wash basin to move forward, driving the switching rod 121 of the women's wash basin to rotate; when the second button 22 is released, the switching rod 121 of the women's wash basin retreats under the elastic force of the control spring 123 of the women's wash basin, and the retreat stroke is greater than the forward stroke. The protruding block 1211 of the women's wash basin pushes the limiting rib 1411 of the women's wash basin to retreat, and the compression spring force of the control spring 123 of the women's wash basin is greater than the compression spring force of the reset spring 142, thereby driving the back pressure rod 141 to retreat against the force of the reset spring 142, and the back pressure pad 143 leaves the back pressure hole 321; at the same time, the second button 22 is pressed, and the meshing tooth 221 pushes the second contact 612 on the rocker rod 61, and the push rod 62 moves forward under the drive of the rocker rod 61, and the pull rod 63 is in the distal state. At this time, the spray gun 64 is in the women's wash basin position, thereby realizing water inlet of the women's wash basin. Press the second button 22 again to push the control rod 122 for controlling the women's wash forward, driving the switching rod 121 of the women's wash to rotate; when the second button 22 is released, the switching rod 121 of the women's wash retreats under the elastic force of the control spring 123 of the women's wash. Due to the limitation of the rib 1111, the retreat stroke is smaller than the forward stroke. At this time, the protruding block 1211 of the women's wash does not contact the limiting rib 1411, and the back pressure rod 141 drives the back pressure pad 143 to press the back pressure hole 321 under the action of the reset spring 142. The water flows in from the hole groove of the needle valve between the rubber pad 33 and the upper cover 32. Since the back pressure hole 321 is closed, the rubber pad 33 presses the water inlet on the water flow body 31 under the action of water pressure to stop the water flow of the women's wash.

[0065] refer to Figure 15 to Figure 22 As shown, the second button 22 is rotated clockwise, and the meshing teeth 221 mesh with the adjusting gear 42. The adjusting gear 42 drives the transmission rod 41, thereby driving the adjusting plate 44 to rotate synchronously. Water can only flow out from the opening 441. By controlling the relative position of the opening 441 and the water outlet 341, the area through which water passes is controlled, thereby achieving flow regulation.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
