[0002] The magnetic levitation box in prior art is usually designed as a hollow sealed box body, mainly composed of upper cover and lower cover, and forms airtight space through glue sealing structure. Although this design can realize the basic function of magnetic levitation box, the following problems are exposed in long-term use:
[0003] The sealed box usually needs to be sealed by glue between the upper cover and the lower cover. Due to processing and assembly errors, the diameter of the positioning socket is prone to shift. After the positioning socket shifts, the matching accuracy with the guide column decreases, and the magnetic levitation box is prone to jamming when sliding along the guide column, affecting the normal operation of the equipment.
[0004] The glue of the sealed box may fall off or run after long-term immersion in water. This not only causes the diameter of the positioning socket to further decrease, exacerbating the jamming problem, but also affects the overall performance and life of the magnetic levitation box.
[0005] The manufacturing process of the sealed box is complex, requiring multiple processes, including precise sealing treatment and strict assembly requirements. This makes the production cost higher and difficult to maintain economic efficiency in large-scale applications.

[0073] Further, an air inlet pipe is also included, which is in communication with the air inlet.
[0074] Principle of automatic water replenishment and automatic water supply stop of the water bottle:
[0075] The integrated water tank 1 realizes the automatic water replenishment and stop water supply function through the unique water bottle plug-in interface 41. When the water bottle is plugged into the water bottle plug-in interface 41, the water in the water bottle flows into the water storage area 4 until the water level of the water storage area 4 rises to the same height as the water bottle plug-in interface 41, forming a water seal. At this time, the water in the water bottle cannot continue to drop due to pressure balance, and the water supply is automatically stopped. When the water level of the water storage area 4 drops due to equipment operation, the water in the water bottle will automatically flow into the water storage area 4 to replenish the water, ensuring continuous water supply of the equipment, without the need for additional electrically controlled water level sensors, realizing automatic and low-cost water supply control.
[0076] The principle of balancing the water level to ensure that the instant heater 2 does not dry out:
[0077] The instant heater 2 is connected to the overflow port 43 of the water storage area 4 through a connecting pipe, and a balance water level is formed by the difference in height between the overflow port 43 and the outlet of the instant heater 2.
[0078] The water in the water storage area 4 is pumped into the instant heater 2 by the water pump 3, and when the water level of the instant heater 2 reaches or exceeds the height of the overflow port 43, the excess water flows back to the water storage area 4 through the connecting pipe.
[0079] Since the outlet of the instant heater 2 is lower than the height of the overflow port 43, this design ensures that there is always enough water in the instant heater 2, and it will not dry out due to lack of water.
[0080] The balance water level mechanism does not rely on electronic sensors, but adjusts the water flow circulation through a simple physical height difference, which is stable and reliable, and avoids the safety hazard of dry burning.
[0081] The magnetic floating box 7 in the water storage area 4 and the normally closed micro switch 8 together constitute a water shortage protection system:
[0082] The magnetic floating box 7 is built-in with a first magnet 71, which floats with the water level of the water storage area 4 rising or falling. When the water level is too low, the magnetic floating box 7 moves down, and the first magnet 71 approaches the second magnet 81 arranged in the control part of the normally closed micro switch 8.
[0083] The first magnet 71 and the second magnet 81 repel each other and push the control part of the normally closed micro switch 8 to act, disconnecting the power supply of the instant heater 2.
[0084] Through this design, when the water storage area 4 is short of water, the equipment automatically stops running, avoiding the risk of dry burning due to lack of water, and at the same time, without the need for complex electronic sensors, the cost and failure rate are reduced.
[0085] In addition, the instant heater 2 stops running, but the water pump 3 still works normally to pump the residual water in the water storage area 4 into the instant heater 2 for storage. This design ensures that there is always water in the instant heater 2, which can be directly supplied when starting next time, thereby avoiding the dry burning problem when starting for the first time.
[0086] The device is fully mechanically controlled through the normally open and normally closed micro switches 8, and has high reliability:
[0087] The main switch is connected in series in the circuit and serves as a key control element for starting the device. The user can start the device by manually closing the main switch, which is simple to operate.
[0088] The normally closed micro switch 8 is linked with the magnetic floating box 7. When the water storage area 4 is out of water, the normally closed micro switch 8 disconnects the instant heater 2, stopping the instant heater 2 from running.
[0089] The fully mechanical design discards the complex electronic control system, and realizes the functions of starting, running, and water shortage protection of the instant heater 2 through the water level floating control of the normally closed micro switch 8. The control of the main switch controls the on-off of all devices, greatly improving the reliability and stability of the device, and reducing the manufacturing and maintenance costs.
[0090] The magnetic floating box 7 adopts a hollow and open-bottom box body 72 design, which has the following advantages:
[0091] The hollow and open-bottom box body 72 allows the inner cavity of the box body 72 to directly contact with the water in the water storage area 4 through the bottom, reducing the self-weight of the box body 72 and improving its buoyancy. This design enables the magnetic floating box 7 to easily float with the water level in the water storage area 4, accurately reflecting the current water level state.
[0092] The box body 72 of the magnetic floating box 7 is provided with an exhaust gap 722, which has the following advantages:
[0093] The exhaust gap 722 is provided on the side wall of the box body 72, which can connect the inner cavity of the box body 72 with the outside air.
[0094] When the bottom of the box body 72 contacts the bottom of the water storage area 4, water may enter the inner cavity of the box body 72, forming a sealed space. In this case, the pressure difference between the inside and outside of the box body 72 may cause the box body 72 to be tightly attached to the bottom of the water storage area 4 due to the adsorption effect, losing the floating function. Since the box body 72 of the present patent is provided with the exhaust gap 722, which provides an air flow channel, balances the pressure inside and outside the box body 72, and avoids the adsorption phenomenon caused by the water sealing effect or pressure difference, ensuring that the box body 72 can normally float with the water level.
[0095] The drain port 42 is located within the projection range of the magnetic floating box 7, which has the following advantages:
[0096] The drain port 42 is in the projection range of the magnetic levitation box 7, which can ensure that when the water storage area 4 is short of water, the water accumulation at the bottom of the magnetic levitation box 7 is quickly reduced, avoiding water accumulation under the magnetic levitation box 7, so that the magnetic levitation box 7 quickly moves down, triggering the action of the normally closed micro switch 8, avoiding delay or misjudgment;
[0097] Moreover, the presence of the drain port 42 reduces the water accumulation at the bottom of the magnetic levitation box 7, thereby reducing the adsorption force caused by the water seal effect;
[0098] In combination with the exhaust gap 722 of the side wall of the box body 72, the problem of the magnetic levitation box 7 being adsorbed at the bottom of the water storage area 4 can be more effectively avoided, and the free movement of the magnetic levitation box 7 is ensured.
