Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Furthermore, the drawings are merely schematic illustrations of the utility model and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.
The present exemplary embodiment first provides a tank overflow 101. Referring to fig. 1 and 2, the tank overflow 101 may include: support 1011, connecting rod 1013, buoyancy 1014, and spacer 1015. A tank overflow 101 can be mounted to the upper port of a tank overflow 102 of the tank 100. The top end and the bottom end of the support 1011 are open and communicated, the side wall of the support 1011 is of a closed structure, and the support 1011 is provided with a guide hole 1012 penetrating through the top end and the bottom end. A spacer 1015 is disposed within the support 1011 to close the opening at the bottom end of the support 1011 when moving downward and to open the opening at the bottom end of the support 1011 when moving upward. The connecting rod 1013 is movably passed through the guide hole 1012 of the support 1011, the lower end of the connecting rod 1013 is connected to the spacer 1015, and the upper end of the connecting rod 1013 is exposed from the top end of the support 1011. A buoyant 1014 is attached to the upper end of the connecting rod 1013.
When the water tank overflow device 101 works, when the water level in the water tank 100 does not reach the overflow water level, the isolating piece 1015 seals the upper port of the whole water tank overflow pipe 102 through the bottom opening of the sealing support piece 1011 under the action of gravity, so that the communication between the water tank 100 and the outside is isolated, and the water quality in the water tank 100 is prevented from being influenced by the flying of small insects such as mosquitoes and the like; when the water level in the water tank 100 exceeds the overflow water level, the buoyancy member 1014 rises under the action of buoyancy and drives the partition member 1015 to rise through the connecting rod 1013, the partition member 1015 no longer seals the bottom opening of the support member 1011, so that the sealing structure of the partition member 1015 and the upper port of the water tank overflow pipe 102 is broken, at the moment, the water in the water tank 100 can flow out through the water tank overflow pipe 102, and the normal drainage function of the water tank overflow pipe 102 cannot be influenced; when the water level in the tank 100 returns to a normal level, the buoyancy 1014, connecting rod 1013, and spacer 1015 are simultaneously lowered by gravity, and the spacer 1015 re-seals the upper port of the tank overflow 102.
Thus, on the one hand, when the water level in the water tank 100 does not reach the overflow water level, small insects such as mosquitoes are prevented from entering the water tank 100 through the water tank overflow pipe 102 to pollute the water in the water tank 100; on the other hand, when the water level in the tank 100 exceeds the overflow level, the drainage function of the tank overflow tube 102 is not affected.
In one embodiment, the shape of the spacer 1015 matches the configuration of the bottom lumen of the support 1011, for example, further, in this example, the diameter of the bottom lumen of the support 1011 decreases and the diameter of the outer peripheral wall of the spacer 1015 decreases in the direction from the top end to the bottom end of the support 1011. This allows the spacers 1015 to move freely up and down within the support 1011 by buoyancy or gravity.
In one embodiment, the isolation member 1015 has a truncated cone shape, which facilitates the movement of the isolation member 1015 in the support member 1011, and has better sealing performance. This example is a specific example of the above embodiment, wherein the support 1011 and the spacer 1015 may also adopt other matching shapes, for example, the support 1011 has a quadrangular frustum structure.
In one embodiment, the maximum clearance between the guide hole 1012 of the support 1011 and the connecting rod 1013 is 0.3mm, the length of the guide hole 1012 is 2 times the diameter of the connecting rod 1013, and the guide hole 1012 of the support 1011 is located at the center of the support 1011 in the up-down direction. By limiting the gap between the guide hole 1012 and the connecting rod 1013 and limiting the length of the guide hole 1012, the connecting rod 1013 is limited so as not to swing left and right and prevent the connecting rod 1013 from moving up and down due to buoyancy or gravity.
In one embodiment, buoyancy member 1014 is a ball float and spacer 1015 is a plug. And the buoyancy 1014 experiences a greater buoyancy in water than the gravity of the spacer 1015. The condition that the floating ball can not drive the rubber plug under the action of buoyancy force due to overlarge gravity of the rubber plug is avoided. When the water level in the water tank 100 exceeds the overflow water level, the buoyancy member 1014 rises under the action of buoyancy and drives the partition 1015 to rise through the connecting rod 1013, so that the sealing structure of the partition 1015 and the upper port of the water tank overflow pipe 102 is broken, at the moment, the water in the water tank 100 can flow out through the water tank overflow pipe 102, and the normal drainage function of the water tank overflow pipe 102 cannot be influenced;
also provided in this example embodiment is a tank 100, the tank 100 comprising the tank overflow 101 and a tank overflow 102. The bottom end of the support 1011 of the tank overflow 101 is mounted to the upper port of the tank overflow 102, and the upper port of the tank overflow 102 is located within the body of the tank 100. This makes it possible to apply the tank overflow 101 of the present exemplary embodiment to various types of tanks 100 having the above-described configuration.
In one embodiment, the outer diameter of the bottom end of the support 1011 is the same as the outer diameter of the upper port of the tank overflow 102. And the bottom end opening of the support 1011 is connected with the upper port of the water tank overflow pipe 102 in a sealing way, and the inside of the support 1011 is communicated with the upper port of the water tank overflow pipe 102 through the opening at the bottom end of the support 1011. When the water level in the water tank 100 does not reach the overflow water level, the upper port of the whole water tank overflow pipe 102 is sealed by the isolating piece 1015, so that the water tank 100 is isolated from the outside, and the water quality in the water tank 100 is prevented from being influenced by the flying of small insects such as mosquitoes and the like.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
