[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0024] At present, ordinary kettles are basically designed for plain areas, and the boiling water temperature is 100℃. That is, when the water temperature reaches about 100℃, the temperature sensor in the kettle senses that the water temperature reaches the set threshold (for example, 100℃), and the switch of the kettle automatically turns off the heating. However, since there are still many high-altitude and low-altitude areas in the world, the boiling point of water will decrease with increasing altitude and increase with decreasing altitude.

[0025] Therefore, when the kettle is at a high altitude, the boiling temperature of the water becomes lower. No matter how long it is heated, the water temperature will never reach 100℃. The 100℃ threshold set by the heating switch of a traditional kettle will never be triggered, so the kettle will keep working, which will lead to two consequences: 1. The water continues to boil, splashing around or causing the socket to become dirty or short-circuited; 2. Continuous boiling and heating will cause the water in the kettle to evaporate, resulting in the risk of dry boiling and fire.

[0026] In order to solve the above problems, the present application provides a kettle, which is as follows:

[0027] See also Figure 1 and Figure 2The embodiment of the utility model provides a hot water kettle, comprising: a base 1 and a kettle body 2, wherein the kettle body 2 is provided with a heating switch 21, and the base 1 or the kettle body 2 is also provided with a height detector 3, the height detector 3 is used to detect the altitude, and the heating switch 21 is used to turn on or off the heating of water in the kettle body 2, wherein the temperature of the water in the kettle body 2 heated to the boiling point corresponds to the altitude.

[0028] The kettle provided in this embodiment can use the altitude detector 3 to detect the altitude of the area where the kettle is located, and the boiling point temperature of water is fixed at each altitude. Therefore, when heating the water in the kettle body 2, the water can be heated to the boiling point temperature at the altitude and then the heating of the water in the kettle body 2 can be turned off by using the heating switch 21. The water will not be boiled all the time, and the water will not dry up and cause a fire.

[0029] Among them, the hot water kettle of the present application also has a temperature sensor for sensing the temperature of the water in the kettle body 2. After the temperature sensor senses that the water temperature has reached the boiling point of water at the current altitude, the heating switch 21 is turned off to turn off the heating of the water in the kettle body 2. Since the technology of automatically turning off the boiling water switch of the hot water kettle is relatively common, it will not be repeated in this embodiment.

[0030] In one embodiment, the kettle further comprises a handle 4 , which is disposed on the kettle body 2 ; wherein a cavity 41 is provided inside the handle 4 , and when the height detector 3 is disposed on the kettle body 2 , the height detector 3 is accommodated in the cavity 41 .

[0031] In this embodiment, the height detector 3 is arranged in the cavity 41 opened in the handle 4, which can protect the height detector 3. This is because when the water boils or the surface of the kettle is exposed to the outside world, a small amount of water may be stained. If this water contacts the height detector 3 many times, it may cause the height sensor to malfunction or fail. Therefore, the height detector 3 is arranged in the cavity 41 opened in the handle 4 to protect the height detector 3.

[0032] In other embodiments, the height detector 3 may also be disposed in the base 1 . The base 1 is provided with a receiving cavity, and the height detector 3 is disposed in the receiving cavity, which can also provide protection for the height detector 3 .

[0033] In one embodiment, the height detector 3 is a barometer, and the handle 4 is provided with an air pressure hole 42 , which connects the cavity 41 with the outside.

[0034] In the present embodiment, the altimeter is a barometer. This is because the boiling point of water depends on the atmospheric pressure. Changes in altitude will change the atmospheric pressure, thereby changing the boiling point of water. Therefore, the atmospheric pressure is directly measured using a barometer. The boiling point of water can be directly determined based on the atmospheric pressure value. Since the comparison of the boiling point of water under different atmospheric pressures is a known technology, it will not be repeated in this embodiment.

[0035] Since the barometer needs to measure the atmospheric pressure outside the kettle, when the air pressure hole 42 connects the cavity 41 with the outside, the air pressure inside the cavity 41 is the same as the air pressure outside, and the barometer can also measure the air pressure value outside in the cavity 41.

[0036] In other embodiments, the altimeter can also be a GPS (Global Positioning System) module. The GPS can obtain the longitude and latitude coordinates of the area where the kettle is located. On the earth, the altitude of each area corresponding to the longitude and latitude coordinates is fixed. Once the altitude is determined, the air pressure value is also determined, so that the boiling point of water can be directly determined based on the atmospheric pressure value.

[0037] See also Figure 2 and Figure 3 In one embodiment, the air pressure hole 42 is opened at one end of the handle 4 close to the base 1 .

[0038] In this embodiment, by opening the air pressure hole 42 at the end of the handle 4 close to the base 1, the probability of water from the outside of the kettle entering the cavity 41 through the air pressure hole 42 can be reduced. Even if water from the outside enters the cavity 41 from the air pressure hole 42, the water can quickly flow out of the cavity 41 under the action of gravity, thereby reducing the contact time between the altimeter and the water.

[0039] See also Figure 2 and Figure 3 In one embodiment, a waterproof breathable membrane 43 is further provided on the handle 4; wherein the waterproof breathable membrane 43 is arranged in the air pressure hole 42 and abuts against the peripheral wall of the air pressure hole 42, or the waterproof breathable membrane 43 is arranged on the outer surface of the kettle body 2 or the inner wall of the cavity 41 and covers the air pressure hole 42.

[0040] In the present embodiment, the provision of the waterproof breathable membrane 43 can prevent external water from entering the cavity 41 through the air pressure hole 42 and contacting the altimeter, and the waterproof breathable membrane 43 is provided in the air pressure hole 42 and abuts against the peripheral wall of the air pressure hole 42. The waterproof breathable membrane 43 provided in this way can not only completely block the water entering the air pressure hole 42, but also be contained in the air pressure hole 42 instead of being directly exposed to the outside world. If it is directly exposed to the outside world, the user of the kettle may touch the waterproof breathable membrane 43 and damage the waterproof breathable membrane 43 when picking up or putting down the handle 4 multiple times, making the waterproof breathable membrane 43 ineffective.

[0041] In other embodiments, the waterproof breathable membrane 43 is disposed on the outer surface of the kettle body 2 . In this embodiment, the waterproof breathable membrane 43 thus disposed covers the air pressure hole 42 , and can also completely block water entering the air pressure hole 42 .

[0042] In other embodiments, the waterproof breathable membrane 43 is arranged on the inner wall of the cavity 41 and covers the air pressure hole 42. In this embodiment, the waterproof breathable membrane 43 arranged in this way covers the air pressure hole 42, and can also completely block the water entering the air pressure hole 42, and the waterproof breathable membrane 43 is not exposed to the outside world.

[0043] See also Figure 2 and Figure 3 In one embodiment, a protective cover 44 is further provided on the handle 4 to form a barrier between the waterproof breathable membrane 43 and the outside world; wherein the protective cover 44 is detachably assembled to the air pressure hole 42 of the handle 4, or the protective cover 44 is rotatably assembled to the air pressure hole 42 of the handle 4, or the protective cover 44 is fixedly assembled to the air pressure hole 42 of the handle 4 and the protective cover 44 is provided with a through hole.

[0044] In this embodiment, the protective cover 44 can form a barrier between the waterproof breathable membrane 43 and the outside world to prevent external objects or the user's hands from directly contacting the waterproof breathable membrane 43 and causing damage to the waterproof breathable membrane 43. The protective cover 44 with a through hole can ensure that the waterproof breathable membrane 43 is not damaged while ensuring ventilation. Exemplarily, when the protective cover 44 is detachably assembled to the air pressure hole 42 of the handle 4, the protective cover 44 and the handle 4 can be snap-fitted, magnetically assembled, etc.; when the protective cover 44 is rotatably assembled to the air pressure hole 42 of the handle 4, the protective cover 44 and the handle 4 can be assembled by a rotating axis, or by a hinge structure.

[0045] In one embodiment, the kettle also includes a timer, which is communicated with the heating switch 21. The timer is used to count after the water in the kettle body 2 is heated to the boiling point, and sends a shutdown signal after the timing is completed. The heating switch 21 is also used to receive the shutdown signal and shut down the heating of the water in the kettle body 2 after receiving the shutdown signal.

[0046] In this embodiment, by using a timer, the heating switch 21 can turn off the heating after the water reaches the boiling point for a predetermined time, thereby achieving an automatic power-off effect.

[0047] See also Figure 2 and Figure 3 In one embodiment, the kettle further includes at least two boiling point selection gears 5, which are arranged on the base 1 or the kettle body 2, each boiling point selection gear 5 corresponds to a boiling point temperature of water, and the boiling point temperature of water corresponding to each boiling point selection gear 5 is different.

[0048] In this embodiment, the user can adapt to the boiling point temperature of water at the current altitude by manually selecting different gears 5, so that the kettle provided in this embodiment can more intuitively display the boiling point temperature of water to the user at different altitudes. In other embodiments, in order to further intuitively display some information, such as altitude, boiling point temperature of water, current temperature of water and other information, a display can also be set on the kettle to display the above information.

[0049] In one embodiment, the kettle further includes gear position markings 6, the number of the gear position markings 6 is the same as the number of the boiling point selection gears 5 and corresponds one to one, and the gear position markings 6 at least include an altitude marking and a boiling point temperature marking.

[0050] In this embodiment, by providing the gear position mark 6 , it is convenient for the user to select different gear positions 5 .

[0051] In one embodiment, the base 1 and the kettle body 2 are integrally provided, or the base 1 and the kettle body 2 are detachably assembled.

[0052] In this embodiment, the base 1 and the kettle body 2 are detachably assembled. When the user uses the kettle, the user does not need to lift the base 1, which makes it easier for the user to use the kettle to collect water and pour water. In other embodiments, the base 1 and the kettle body 2 are integrated. The kettle configured in this way can improve the integrity of the kettle and is more convenient for the user to move the kettle.

[0053] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
