Abstract
Description
Technical Field
[0001] This utility model belongs to the field of kettle technology, specifically relating to a color-changing kettle. Background Technology
[0002] An electric kettle is a common household appliance or kitchen appliance, mainly used to quickly heat water. It works by using a heating element to convert electrical energy into heat energy, which then heats the water to boiling through conduction and convection. Electric kettles typically have an automatic shut-off function, which cuts off the power once the water boils to prevent dry boiling.
[0003] In daily life, kettles are often used with a base when boiling water, and the bottom of the base has a coupler. After boiling, the user removes the kettle from the base and places it on a table or other surface. At this time, the coupler at the bottom of the kettle is exposed, and debris may enter, affecting its use. For example, food scraps not cleaned from the table, small toy parts, etc., may enter the coupler at the bottom of the kettle, and may even damage the coupler. Therefore, this application provides a kettle that can effectively prevent debris from entering the coupler.
[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0005] The purpose of this invention is to provide a color-changing kettle to effectively prevent foreign matter from entering the coupler at the bottom of the kettle.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A color-changing kettle includes a kettle body; the outer surface of the kettle body is coated with a thermosensitive color-changing coating.
[0008] Preferably, the thermochromic coating is in the shape of a cube and is located on the lower half of the outer surface of the kettle body.
[0009] Preferably, the kettle body has a receiving groove at the bottom, and a coupler is provided at the center of the top wall of the receiving groove; a baffle is also provided in the receiving groove, and a clearance hole 1 is provided at the center of the baffle and is fixed to the top wall of the receiving groove by a semi-threaded bolt; a clearance hole 2 is provided at one end of the baffle, and the clearance hole 2 corresponds to the position of the coupler; two symmetrical clearance holes 3 are also provided on the baffle, and the two clearance holes 3 are respectively located on both sides of the clearance hole 1; a ball-head plunger that mates with the clearance hole 3 is also provided on the top wall of the receiving groove.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] (1) The color-changing kettle of this utility model is coated with a thermosensitive color-changing coating on the outer surface of the kettle body, which makes it convenient for users to observe the water temperature inside the kettle and can play a warning and reminder role to avoid scalding.
[0012] (2) The color-changing kettle of this utility model has a rotatable baffle at the bottom of the kettle body. The baffle can cover the coupler at the bottom of the kettle body when not boiling water, effectively preventing foreign objects from entering the coupler at the bottom of the kettle and avoiding damage to the coupler due to foreign objects entering.

[0018] The technical solution of this utility model patent will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] See attached document Figure 1-2 A color-changing kettle includes a kettle body 1; the outer surface of the kettle body 1 is coated with a thermosensitive color-changing coating 2, the thermosensitive color-changing coating 2 is square-shaped and located on the lower half of the outer surface of the kettle body 1.
[0022] The thermochromic coating 2 can be prepared by using chlorophenol red as the thermochromic host and octadecyltrichlorosilane as the coating material, through a reaction at the water and oil / water emulsion interface. It exhibits a distinct and completely reversible color change. This material has undergone cytotoxicity testing, proving it to be non-toxic and suitable for applications such as food packaging and smart sensors.
[0023] On the other hand, the kettle body 1 has a receiving groove 3 at the bottom, and a coupler 4 is provided at the center of the top wall of the receiving groove 3; a baffle 5 is also provided in the receiving groove 3, and a clearance hole 6 is provided at the center of the baffle 5 and it is fixed to the top wall of the receiving groove 3 by a semi-threaded bolt 7; a clearance hole 8 is provided at one end of the baffle 5, and the clearance hole 8 corresponds to the position of the coupler 4; two clearance holes 9 are also provided on the baffle 5, which are symmetrically positioned, and the two clearance holes 9 are located on both sides of the clearance hole 6; a ball-head plunger 10 that mates with the clearance hole 9 is also provided on the top wall of the receiving groove. When water needs to be boiled, the user manually moves the baffle 5 so that the baffle 5 rotates along the semi-threaded bolt 7 until the clearance hole 2 8 corresponds to the position of the coupler 4 at the bottom of the kettle body 1, so that the lower coupler on the matching base can pass through the clearance hole 2 8 and connect with the coupler 4 at the bottom of the kettle body 1. After power is turned on, water is boiled; at this time, the ball plunger 10 on the top wall of the receiving groove 3 enters into one of the clearance holes 3 9 on the baffle 5.
[0024] After boiling water, the user removes the kettle body 1 from the matching base and places it on a flat surface such as a table. Before this, the user can rotate the baffle 5 along the semi-threaded bolt 7 by moving the baffle 5 again until the other end of the baffle 5 completely covers the second clearance hole 8 to prevent external debris from entering the coupler 4 at the bottom of the kettle body 1; at this time, the ball-head plunger 10 on the top wall of the receiving groove 3 enters another third clearance hole 9 on the baffle 5.
[0025] This utility model of a color-changing kettle uses a thermosensitive color-changing coating 2 applied to the outer surface of the kettle body 1, and a rotatable baffle 5 installed in the receiving groove 3 at the bottom of the kettle body 1 to shield the coupler 4. This not only warns users to be careful to avoid scalding, but also effectively prevents debris from entering the coupler 4 at the bottom of the kettle, avoiding blockage and damage to the coupler 4. It is very practical and has good market application prospects.
[0026] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
