AI Technical Summary
The dual float structure in existing water heaters increases costs and poses safety hazards. Furthermore, if one float fails, it may cause the heater to continue operating even when there is no water, leading to a dry-burning accident.
The system employs a float device with two linkages, where a single float controls both the solenoid valve and the power-off switch. This ensures that the power is quickly cut off or the solenoid valve is shut off in case of abnormal water levels, preventing dry burning.
It effectively prevents dry burning caused by abnormal water levels, ensures the safe operation of the water heater, reduces production costs, and improves user safety.

DETAILED DESCRIPTION
[0016] The technical solutions in the embodiments of the device will be clearly and completely described below with reference to the drawings in the embodiments of the device. Obviously, the described embodiments are only part of the embodiments of the device, rather than all the embodiments. Based on the embodiments in the device, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the device.
[0017] The device provided by the device has the advantages that Figs. 1-3A ball two linkage floating ball device of a water boiler, comprising:
[0018] The water heating tank 1 is provided with a water inlet pipe 2, and the water inlet pipe 2 is provided with an electromagnetic valve 3 at one end in the water heating tank 1. A floating ball 4 is arranged in the water heating tank 1, and an L-shaped support 5 is fixed on the top of the floating ball 4 by bolts. One end of the L-shaped support 5 is connected with a first connecting rod 6. A second connecting rod 11 is rotatably connected to the water heating tank 1 through a rotating seat 7. The floating ball 4 is floated up and down in the water heating tank 1, so that when the floating ball 4 is floated up, the electromagnetic valve 3 is controlled to be opened through the first connecting rod 6, and when the floating ball 4 is floated down, the power-off switch 8 on the surface of the water heating tank 1 is controlled to be powered off through the second connecting rod 11.
[0019] The L-shaped support 5 is provided with a movable groove 9, and one end of the second connecting rod 11 movably penetrates the movable groove 9.
[0020] One end of the second connecting rod 11 connected with the rotating seat 7 is connected with a top rod 10. One end of the top rod 10 movably penetrates a slot provided in the water heating tank 1, and a movable rubber strip 12 is arranged in the slot. On the one hand, the movable rubber strip 12 can play a sealing role to prevent the liquid in the water heating tank 1 from leaking out of the slot, and ensure the relative stability of the internal environment of the water heating tank 1. On the other hand, the movable rubber strip 12 has a certain elasticity and flexibility, which will not hinder the normal movement of the top rod 10 in the slot, and allows the top rod 10 to move smoothly in the slot, so that the whole structure can not only meet the sealing requirements but also meet the movement function requirements.
[0021] The power-off switch 8 is connected with a push spring 13 on the surface, and the other end of the push spring 13 extends to the top of the top rod 10. The power-off switch 8 is electrically connected with a contact 14 on the surface. When the second connecting rod 11 moves, the push spring 13 contacts the contact 14, which triggers the power-off switch 8 to act, cuts off the circuit, and stops the water boiler from heating
[0022] The bottom of the water heating tank 1 and the bottom of the water inlet pipe 2 are both provided with a proximity switch 15.
[0023] The first connecting rod 6 and the water heating tank 1 are also rotatably connected with a support rod 16 through the rotating seat 7. The support rod 16 plays a supporting role to support the first connecting rod 6 when it rotates, and enhances the stability of the whole structure.
[0024] The ball two linkage of the water boiler device, the initial state, the water level in the water boiler 1 is low, the float ball 4 is in a low position, when the water is needed, the external water source is connected with the water inlet pipe 2, because the float ball 4 is low (at this time the electromagnetic valve 3 is opened by default), with the external water source pressure, the water begins to flow into the water inlet pipe 2 and into the water boiler 1, with the water continuously flowing into the water boiler 1, the water level gradually rises, the float ball 4 floats upwards, the rising of the float ball 4 drives the L-shaped support 5 fixed by bolts at the top to move upwards, the first connecting rod 6 connected with one end of the L-shaped support 5, in the process of the float ball 4 rising, the connecting point of the float ball 4 and the L-shaped support 5 rises, and the support rod 16 rotatingly connected between the first connecting rod 6 and the water boiler 1 through the rotating seat 7, so that the connecting part of the first connecting rod 6 and the support rod 16 rotates through the rotating seat 7, and one end of the first connecting rod 6 is lifted upwards, when the first connecting rod 6 is lifted upwards, when the first connecting rod 6 is lifted to the distance close to the sensing surface of the proximity switch 15 that can be sensed, the proximity switch 15 will send a signal, and transmit to the control chip (not shown in the figure) on the surface of the water boiler 1, the control chip sends a control signal after processing, and controls the electromagnetic valve 3 to be closed, at this time the water inlet pipe 2 stops water, and the water boiler 1 is realized to be filled with water.
[0025] When the water level is lowered due to water use, the float ball 4 moves downwards, at this time, the second connecting rod 11 movably penetrating in the movable slot 9 in the L-shaped support 5, one end of the second connecting rod 11 is pulled downwards by the L-shaped support 5 when the float ball 4 moves downwards, the other end of the second connecting rod 11 rotates through the rotating seat 7, and when one end of the second connecting rod 11 rotates, the top rod 10 in the slot is lifted and the top rod 10 lifts the actuating spring 13 to make the actuating spring 13 contact with the contact 14, which triggers the action of the power-off switch 8, cuts off the circuit, and stops the water boiler from heating;
[0026] At this time, the float ball 4 drives the first connecting rod 6 to move to the bottom of the water boiler 1, when the sensing surface of the proximity switch 15 at the bottom of the water boiler 1 senses the first connecting rod 6, the electromagnetic valve 3 is controlled to be opened, at this time water can be added to the water boiler 1 through the water inlet pipe 2;
[0027] With the rising of the water level, the float ball 4 moves upwards and pushes the second connecting rod 11 upwards through the L-shaped support 5, at this time, the other end of the second connecting rod 11 continues to rotate through the rotating seat 7, and drives the top rod 10 at one end of the second connecting rod 11 to move downwards, so that the top rod 10 is separated from the force of upward movement on the actuating spring 13, and then the actuating spring 13 is reset and separated from the contact 14, so that the power-off switch 8 acts again, the circuit is opened, and the water boiler starts to heat, so that the water boiler can keep the working state of water and electricity when there is water and electricity, and no water and electricity when there is no water.
[0028] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
