Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

Referring to fig. 1 and 2, a steam switch device for a hot water kettle comprises a kettle body 10, a kettle cover 20 and a steam channel 40, wherein a water storage cavity 11 is formed inside the kettle body 10, the top end of the water storage cavity 11 is open, a water outlet 13 is arranged on one side of the kettle body 10, the water outlet 13 can be communicated with the top end of the water storage cavity 11, and the steam channel 40 is arranged on the other side of the kettle body 10. The bottom end of the kettle body 10 is provided with a mounting cavity 12, and the steam temperature sensing element can be arranged in the mounting cavity 12.

Specifically, the pot lid 20 is provided with a connecting handle 27 and a locking lid 26, one end of the connecting handle 27 is connected to the top end of the pot body 10, and the other end of the connecting handle 27 is fixed to the locking lid 26. In this way, the handle 27 can rotate with respect to the body 10, and during the rotation of the handle 27, the lid 26 can be driven to rotate towards or away from the opening. The locking cover 26 can be locked at the top opening of the water storage cavity 11 after rotating near the opening. When the fastening cover 26 is fastened in the opening, the outer peripheral wall of the fastening cover 26 and the inner wall of the opening are spaced to form a steam gap 30.

In addition, the outer peripheral wall of the buckling cover 26 is provided with a steam inlet 21 and a steam outlet 23; the buckling cover 26 is internally provided with a steam guide cavity 22; one end of the steam inlet 21 is communicated with the steam gap 30; the other end of the steam inlet 21 is communicated with one end of the steam guide cavity 22; the other end of the steam guide cavity 22 is communicated with one end of the steam outlet 23; the other end of the steam outlet 23 is used for being communicated with the top end of the steam channel 40 when the buckling cover 26 is buckled in the opening; the bottom end of the steam channel 40 is communicated to the mounting cavity 12; the steam outlet 23 is located above the steam inlet 21; the steam inlet 21 is higher than the water outlet 13.

On the basis of the structure, use the utility model discloses a during steam switch device for thermos, can adorn water in water storage chamber 11, then rotate through the connecting handle 27, it rotates to drive the top end opening rotation of locking lid 26 towards water storage chamber 11, make locking lid 26 lock on the opening, begin to boil water behind the switch on, and at the in-process of boiling water, the steam that produces behind the water boiling can be by the leading-in steam inlet 21 of steam clearance 30 of pot lid 20 periphery wall and opening inner wall interval formation, steam inlet 21 gets into behind the steam guide chamber 22 and derives to steam channel 40 in steam outlet 23, guide to installation cavity 12 through steam channel 40 again, control the steam temperature-sensing element operation in the installation cavity 12, in time break off.

Namely, the steam can be conducted to the steam channel 40 in the steam guide cavity 22, when the water is boiled or exceeds the water level, the water can only enter the steam guide cavity 22, and when the water level is too high, the steam inlet 21 is higher than the water outlet 13 on the kettle body 10, so that the water can be discharged through the water outlet 13 of the kettle body 10 and can not enter the steam channel 40, and the water in the kettle body 10 can be prevented from entering the steam channel 40 when the water is boiled or exceeds the water level. Furthermore, the steam outlet 23 is located above the steam inlet 21, and even if water enters the steam guide chamber 22 through the steam inlet 21, the water is difficult to flow to the steam outlet 23 at a high position without an external force, so that the effect of blocking the water from entering the steam passage 40 is better.

It should be noted that, the steam temperature sensing element in this embodiment is a bimetal deformable at a steam temperature in the prior art, and such deformation pushes the power switch to power off through a lever principle, and how to connect the steam temperature sensing element to the circuit does not belong to the technical content to be protected in this application, and is not described in detail herein.

Furthermore, a handle 50 can be further arranged on the side of the kettle body 10 far away from the water outlet 13, the steam channel 40 is arranged in the handle 50, the top end of the steam channel 40 penetrates through the side surface of the top end of the handle 50, and the end part of the connecting handle 27 is hinged to the top end of the handle 50, so that the connecting handle 27 can be abutted against the top end surface of the handle 50 when rotating towards the opening, the steam outlet 23 on the kettle cover 20 can be communicated with the inlet of the steam channel 40 on the side surface of the top end of the handle 50, the connecting handle 27 can cover the joint gap between the two, and the leakage of steam is reduced.

Of course, the steam channel 40 may be formed by a pipe in the built-in water storage cavity 11, and the top end of the pipe is directly communicated with the steam outlet 23 of the pot lid 20.

Further, the fastening cover 26 in this embodiment includes an upper cover and a lower cover, the upper cover and the lower cover are fixedly connected in a fastening manner to form an installation space, a partition plate 24 is disposed in the installation space, the partition plate 24 is used for dividing the installation space into a cavity 25 and a steam guiding cavity 22, so that a part of the cavity 25 can be reserved inside the pot lid 20 for installation of other parts, and the steam in the steam guiding cavity 22 partitioned by the partition plate 24 does not affect the parts in the cavity 25.

Furthermore, a curve can be arranged in the steam guide cavity 22, the steam inlet 21 and the steam outlet 23 are respectively communicated to two ends of the curve, so that steam enters the steam guide cavity 22 from the steam inlet 21 and can reach the steam outlet 23 through the curve in the steam guide cavity 22, the steam can reach the steam channel 40 only by bending, even if water enters from the steam inlet 21, the curve can effectively prevent water from entering the steam channel 40 through the steam outlet 23, and the effect is better.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
