Description

Technical Field

[0001] The utility model relates to the technical field of electric kettles, in particular to an electric kettle with an ultraviolet generator. Background Art

[0002] The electric kettle uses electric heating elements to increase the water temperature. The electric heating elements are generally electric heating tubes or electric heating plates, which are made of metal materials, so they have high thermal efficiency. When current passes through, the resistor will generate heat, and the heat energy is transmitted to the water molecules through the kettle, thereby achieving the effect of boiling water. Since the water temperature in the electric kettle is basically 100°C after boiling, users usually do not drink it immediately, but let it stand for a period of time and wait for the water temperature in the electric kettle to drop before drinking it. In actual practice, it is found that some users forget to drink water and cause the water in the electric kettle to stay overnight. Overnight water is prone to bacterial growth. Therefore, some existing electric kettles are equipped with ultraviolet LED lamps for sterilization. For example, the utility model patent with authorization announcement number CN206560322U discloses a liquid heating container, which can use ultraviolet rays to kill harmful microorganisms with high temperature resistance in the liquid of the liquid heating container, such as harmful bacteria and viruses, that is, the ability of the liquid heating container to kill harmful microorganisms is improved, thereby improving the safety and health of the liquid, so as to ensure that people drink safer and healthier liquids. However, although ultraviolet rays have a good sterilization effect, ultraviolet LED lamps are installed to stimulate ultraviolet rays for sterilization. But at the same time, ultraviolet rays escape from electrical appliances and irradiate the human body, which will cause certain harm to the human body, and there is room for improvement.

[0026] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figure 1-Figure 4 The embodiment of the utility model discloses an electric kettle, which specifically comprises a kettle body 1, a kettle cover 2 and an ultraviolet generator 3; the kettle body 1 has an opening 11 and a kettle cavity 12 connected to the opening 11, and a spout 13 is arranged at the opening 11 of the kettle body 1; the kettle cover 2 is arranged at the opening 11 of the kettle body 1, and a mouth cover 21 for covering the spout 13 is arranged on the kettle cover 2; the ultraviolet generator 3 is arranged on the kettle cover 2, and the emitting surface of the ultraviolet generator 3 faces the kettle cavity 12.

[0030] In view of the fact that the existing ultraviolet rays escape from electrical appliances and irradiate the human body, it will cause certain harm to the human body, and through research it is found that there are two main areas where ultraviolet rays escape, one is the opening 11 of the kettle body 1, and the other is the spout 13 of the kettle body 1. The two areas have the problem of ultraviolet rays escaping. The reason for the ultraviolet rays escaping is that the ultraviolet rays can escape from the opening 11 and the spout 13 after multiple reflections in the kettle cavity 12 of the kettle body 1. Therefore, the electric kettle is targeted at these two areas and is provided with a kettle cover 2 and a spout cover 21. The kettle cover 2 can cover the opening 11 of the kettle body 1, and the spout cover 21 can cover the spout 13. After covering, the ultraviolet rays can be well prevented from escaping, and the ultraviolet rays can be avoided from escaping from the electric kettle and irradiating the human body, thereby improving the safety of the electric kettle.

[0031] Optionally, the ultraviolet generator 3 can be an ultraviolet LED lamp, which has a simple structure and is easy to manufacture.

[0032] Optionally, the pot cover 2 and the spout cover 21 can be integrally formed, for example, by injection molding, which can reduce the manufacturing cost of the entire machine and improve manufacturing efficiency.

[0033] Optionally, the electric kettle further includes an opening and closing detector, which is used to detect the opening and closing state between the kettle lid 2 and the kettle body, and triggers the ultraviolet generator 3 to turn off when it is detected that the kettle lid 2 is opened. It is further found in the research and development that during the process of the ultraviolet generator 3 being turned on for sterilization, the user may want to open the kettle lid 2 to observe the water capacity in the kettle cavity 12, and judge whether the water in the kettle cavity 12 is enough to drink and whether water needs to be added. At this time, the ultraviolet generator 3 is still in the working state. If the user directly opens the kettle lid 2, there will also be the problem that ultraviolet rays escape from the electrical appliance and irradiate the human body, causing certain harm to the human body. Therefore, by setting the opening and closing detector, the opening and closing detector is used to detect the opening and closing state between the kettle lid 2 and the kettle body, and triggers the ultraviolet generator 3 to turn off when it is detected that the kettle lid 2 is opened. When the user wants to open the kettle lid 2 for observation, the ultraviolet generator 3 will be in an extinguished state. Therefore, when the kettle lid 2 is opened, the problem of ultraviolet radiation can be well avoided, and the safety performance of the electric kettle is further improved.

[0034] Optionally, the opening and closing detector may include a positive contact terminal 41, a negative contact terminal 42, and a conductive terminal 43, wherein the positive contact terminal 41 and the negative contact terminal 42 are electrically connected to the positive and negative electrodes of the ultraviolet generator 3 in a one-to-one correspondence, and the positive contact terminal 41 and the negative contact terminal 42 are both arranged on one of the kettle body and the kettle lid 2, and the conductive terminal 43 is arranged on the other of the kettle body and the kettle lid 2. In specific use, when the user opens the kettle lid 2, the positive contact terminal 41 and the negative contact terminal 42 will be separated from the conductive terminal 43, the circuit where the ultraviolet generator 3 is located cannot form a connected circuit, and the ultraviolet generator 3 is turned off; when the user closes the kettle lid 2, the positive contact terminal 41 and the negative contact terminal 42 will be in contact and connected with the conductive terminal 43, the circuit where the ultraviolet generator 3 is located will form a connected circuit, and the ultraviolet generator 3 will be turned on for sterilization.

[0035] Optionally, both the positive contact terminal 41 and the negative contact terminal 42 can be arranged on the pot cover 2, and the conductive terminal 43 can be arranged on the pot body. Since the ultraviolet generator 3 is also arranged on the pot cover 2, the positive contact terminal 41 and the negative contact terminal 42 are also arranged on the pot cover 2, so that the positive contact terminal 41, the negative contact terminal 42 and the ultraviolet generator 3 can form a circuit well, making the structure more compact.

[0036] In other embodiments, the opening and closing detector includes a micro switch and an abutment portion, the micro switch is arranged on one of the kettle body and the kettle lid 2, and the abutment portion is arranged on the other of the kettle body and the kettle lid 2. In actual use, the micro switch has a simple structure, is easy to manufacture and produce, can reduce the difficulty of manufacturing, and has a mature manufacturing process, which can improve the efficiency of manufacturing. The micro switch and the ultraviolet generator 3 are in the same series circuit, when the micro switch is in the disconnected state, the ultraviolet generator 3 is turned off; when the micro switch is in the connected state, the ultraviolet generator 3 is turned on. In specific use, when the user opens the kettle lid 2, the micro switch is not abutted and triggered at this time, the micro switch will be in the disconnected state, and the ultraviolet generator 3 will be turned off; when the user closes the kettle lid 2, the micro switch is abutted and triggered, the micro switch will be in the connected state, and the ultraviolet generator 3 will be turned on for sterilization.

[0037] Optionally, the micro switch can be arranged on the pot cover 2, and the abutment portion can be arranged on the pot body. Since the ultraviolet generator 3 is also arranged on the pot cover 2, the micro switch is also arranged on the pot cover 2, and a series circuit of the micro switch and the ultraviolet generator 3 can be arranged in the pot cover 2, making the structure more compact. In other embodiments, the micro switch can be arranged on the pot body, and the abutment portion can be arranged on the pot cover 2, and the opening and closing state between the pot cover 2 and the pot body can also be detected.

[0038] In other embodiments, the opening and closing detector may also be a detection device such as a pressure switch, a Hall switch, etc.

[0039] Optionally, the side where the ultraviolet generator 3 is arranged on the pot cover 2 is set as the bottom side, and the bottom side of the pot cover 2 is provided with a groove 22, and the ultraviolet generator 3 is arranged in the groove 22. It is further found in the research and development that if the ultraviolet generator 3 is directly arranged on the bottom side of the pot cover 2, it is easy to bump against the ultraviolet generator 3 during the user's use, thereby causing damage to the ultraviolet generator 3; therefore, the groove 22 is provided on the bottom side of the pot cover 2, and the ultraviolet generator 3 is hidden in the groove 22, and the ultraviolet generator 3 does not protrude from the groove 22, which can effectively solve the problem of bumping against the ultraviolet generator 3, ensure that the ultraviolet generator 3 can be used normally, and also improve the safety of the electric kettle.

[0040] Optionally, the side wall of the groove 22 is an arc-shaped side wall, and the arc-shaped side wall is convexly formed in a direction away from the ultraviolet generator 3. It is further found in the research and development that when the ultraviolet generator 3 is in use, the ultraviolet rays emitted by the ultraviolet generator 3 will be reflected randomly in the pot cavity 12. Although the water in the pot cavity 12 can be sterilized, the sterilization effect is not maximized; therefore, by making the side wall of the groove 22 an arc-shaped side wall, the arc shape is similar to the shape of a spotlight cover. After the ultraviolet rays are reflected, most of the ultraviolet rays will be directly shot to the water in the pot cavity 12, which can better sterilize the water and maximize the sterilization effect.

[0041] Optionally, the electric kettle further includes a reminder device, which is used to send a reminder signal when the ultraviolet generator 3 emits ultraviolet rays. During the research and development, it was further found that since the kettle body and the kettle cover 2 of the electric kettle are usually opaque, the user cannot know whether the ultraviolet generator 3 is in a working state. Therefore, a reminder device is provided on the electric kettle, and the reminder device can send a reminder signal when the ultraviolet generator 3 emits ultraviolet rays, so that the user can judge whether the ultraviolet generator 3 is in a working state through the reminder device, which can greatly enhance the user's experience.

[0042] Optionally, the reminder device can be an indicator light 5, which is arranged on the outside of the kettle body 1 or the kettle lid 2, and the indicator light 5 and the ultraviolet generator are connected in series with the same control switch or control circuit. In this way, when the user opens the kettle lid 2, the circuit where the ultraviolet generator 3 and the indicator light 5 are located cannot form a connected circuit, and the ultraviolet generator 3 and the indicator light 5 are both turned off; when the user closes the kettle lid 2, the circuit where the ultraviolet generator 3 and the indicator light 5 are located will form a connected circuit, the ultraviolet generator 3 is turned on for sterilization, and the indicator light 5 will light up, which can remind that the ultraviolet generator 3 is in working condition.

[0043] Optionally, the indicator light 5 can be an LED lamp. The LED lamp has low cost, simple structure, and occupies a relatively small space, which is easy to manufacture and reduces the manufacturing difficulty.

[0044] Optionally, a transparent observation window 6 is provided on the kettle body 1 or the kettle cover 2, and the indicator light 5 is arranged in the observation window 6. In order to prevent the indicator light 5 from being bumped by the outside of the kettle body 1 or the kettle cover 2, and also to prevent the visible light emitted by the indicator light 5 from being blocked by other objects, the indicator light 5 is arranged in the transparent observation window 6, so that the user can better see the visible light invented by the indicator light 5, and the indicator light 5 can also be better protected.

[0045] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
