Description

Technical Field

[0001] The utility model relates to a temperature controller, in particular to a temperature controller for an electric kettle with high safety, belonging to the technical field of electric kettles. Background Art

[0002] In the prior art, a utility model with publication number 202320868405.1 discloses a highly safe electric kettle thermostat. The utility model provides a boss surrounding the insertion portion under the conductive ring, thereby increasing the creepage distance between the two conductive rings and improving the safety performance of the product. A boss surrounding the connecting plug for fixing the conductive ring is also provided around the connecting plug, further ensuring the creepage distance of the connecting plug position. The other parts of the conductive ring are lifted up by the boss, so that the lower end of the conductive ring has a certain distance from the bottom of the upper coupler base, thereby increasing the creepage distance of the entire conductive ring and avoiding the occurrence of creepage between the conductive rings.

[0003] Similar to the above application, there are still some shortcomings:

[0004] 1. The top of the foreign body in the patient's throat is prone to sticking to physical residues. The existing foreign body forceps cannot clean up the food residues, which affects the judgment and clamping during use, and the functionality is low;

[0005] 2. Since the position and depth of the foreign body are not fixed, the length of the existing pliers is fixed, which is inconvenient to use;

[0006] For this reason, a safe electric kettle thermostat is designed to optimize the above-mentioned problems. Utility Model Content

[0022] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0023] like Figure 1-Figure 4 As shown, the present embodiment provides an electric kettle thermostat with high safety, comprising a kettle 1, an upper coupler base 2 located inside the kettle 1, a kettle seat 3 arranged below the kettle 1, and a lower coupler base 4 plugged with the upper coupler base 2 inside the kettle seat 3, an annular plate 5 is provided on the top of the lower coupler base 4, a first spring 6 is provided between the top of the outer side of the lower coupler base 4 and the inner bottom of the annular plate 5, through grooves 8 are symmetrically provided on both sides of the annular plate 5, and the bottoms of both sides of the lower coupler base 4 are hingedly installed with tilting rods 7, which respectively pass through the inside of the through grooves 8 and extend to the top of the annular plate 5, a second spring 9 is provided between the inner side of the tilting rod 7 and the inner end of the through groove 8, and a covering mechanism for blocking the lower coupler base 4 is provided on the inner top of the annular plate 5.

[0024] The overall working principle is as follows: during use, the upper coupler base 2 is directly fixed to the middle position of the bottom of the kettle 1, and the annular plate 5 is fixed to the top of the kettle seat 3. The lower coupler base 4 is located at the bottom of the annular plate 5 and can extend from the inside of the annular plate 5. When the kettle 1 is placed on the kettle seat 3, when the kettle 1 is loaded with water, the tilting rod 7 will be squeezed outward. The tilting rod 7 is located between the ends of the through groove 8, and the contact point serves as a fulcrum to tilt the bottom end of the tilting rod 7 upward, thereby lifting the lower coupler base 4 upward, extending it upward from the inner circle of the annular plate 5, and inserting it into the interior of the upper coupler base 2 to complete the circuit connection. When there is no water in the kettle 1, the gravity is insufficient and the lower coupler base 4 cannot be tilted. The circuit is in an open circuit state, which can prevent dry burning and is safer to use. In addition, after the kettle 1 is removed, the lower coupler base 4 will be automatically hidden inside the kettle seat 3 by the reset effect of the first spring 6 and the second spring 9.

[0025] In this embodiment, the bottom end of the upper coupler base 2 is higher than the horizontal plane where the bottom end of the kettle 1 is located, and a rubber ring is provided on the outer side of the kettle 1.

[0026] Partial working principle: The inner concave design enables water stains to directly contact the bottom of the upper coupler base 2 during water collection, avoiding short circuit during plugging.

[0027] In this embodiment, the covering mechanism includes a pull rope 10, a partition 11 and a slide groove 13. The inner side of the annular plate 5 is provided with a slide groove 13, and the partition 11 is symmetrically slidably arranged inside the slide groove 13. The ends of the two groups of partitions 11 are fitted together, and a pull rope 10 is installed between the side of the partition 11 and the tilting rod 7.

[0028] Partial working principle: when the control lever 7 is slid outward, the partition 11 is pulled outward by the pull rope 10, and the middle position of the annular plate 5 is connected to the inside of the pot seat 3 to facilitate the extension of the lower coupler base 4.

[0029] In this embodiment, the top of the tilting rod 7 is arc-shaped, and the top of the through slot 8 away from the lower coupler base 4 is arc-shaped.

[0030] Partial working principle: the arc-shaped setting of the end of the tilting rod 7 can reduce the friction when the tilting rod 7 slides, and the arc-shaped setting of the end of the through groove 8 can reduce the wear of the bottom end of the tilting rod 7.

[0031] In this embodiment, hidden grooves 12 are provided on both sides of the bottom of the kettle 1 . The hidden grooves 12 are located directly above the through grooves 8 and are used to hide the top of the tilting rod 7 .

[0032] Partial working principle: ensure that the bottom of the kettle 1 fits with the top of the kettle seat 3, ensuring stability and sealing in use.

[0033] In this embodiment, the end cross-sectional view of the hidden groove 12 is an inverted V shape, and the width of the top of the hidden groove 12 is the same as the diameter of the top of the tilting rod 7 .

[0034] Partial working principle: when the kettle 1 is placed on the kettle seat 3, the position of the cocking rod 7 can be quickly found.

[0035] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
