[0043] With the improvement of people's living standards, electric kettle has become one of the indispensable electrical appliances in home or office. For the user, the use of electric kettle to boil water has various purposes, for example: for tea, coffee and milk operation, there are specific requirements for water temperature. But the electric kettle keeps the water temperature at about 100 degrees when the water is boiled, which cannot flexibly meet the needs of users.

[0044] In the existing electric kettle, the temperature of the water in the electric kettle is usually detected by using an internal temperature sensing bag, and a program is designed to control the heating or stopping of the heating action.

[0045] In the above structure, the installation structure of the internal temperature sensing bag is to open a small hole in the kettle body of the electric kettle, install the internal temperature sensing bag in the small hole and seal it with silica gel. The internal temperature sensing bag can directly detect the water temperature in the kettle. However, the temperature sensing bag is easy to accumulate dirt and damage when it is arranged inside the kettle body.

[0046] Based on the above considerations, in order to solve the above problems, please refer to Figures 1 to 7 In one or more embodiments of the present application, a fixing device 200 is provided for fixing a temperature sensing bag 300 on a heating disc 500 of an electric kettle 100, so as to arrange the temperature sensing bag 300 on the outside of the electric kettle 100, thereby facilitating user maintenance and replacement.

[0047] Specifically, the fixing device 200 includes a main body 20 and a mounting assembly 21. The main body 20 is recessed to form a mounting groove 201 extending in a first direction, and the mounting groove 201 has two groove side walls 202 oppositely arranged in a second direction. The second direction intersects the first direction. The surface of the main body 20 provided with the mounting groove 201 is recessed to form a mounting hole 204. One end of the mounting assembly 21 is arranged in the mounting hole 204 and is matched with the heating disc, and the other end of the mounting assembly 21 extends out of the mounting hole 204 and abuts against the second surface of the main body 20 away from the mounting groove 201, so as to cooperate with the heating disc to clamp the main body 20.

[0048] Among them, the groove bottom wall has a corresponding projection area on the second surface in the self-recess direction; at least part of the mounting assembly 21 abutting against the second surface is located in the projection area, and can exert a force on the temperature sensing bag 300 assembled in the mounting groove 201.

[0049] It can be understood that when the main body 20 is fixed on the heating disc 500 through the mounting assembly 21, the mounting assembly 21 can exert a force on the main body 20 with the second surface pointing to the first surface. The force can make the main body 20 abut tightly against the heating disc 500, thereby realizing stable installation of the main body 20. In the present application, at least part of the mounting assembly 21 is located in the projection area, so as to exert a force on the temperature sensing bag 300 assembled in the mounting groove 201, thereby making the temperature sensing bag 300 abut tightly against the heating disc 500, and realizing stable installation of the temperature sensing bag 300.

[0050] Further, please refer to Figure 5 and Figure 6The mounting assembly 21 comprises a mounting member 211 and a cooperating member 212. The mounting member 211 is arranged in the mounting hole 204 and is connected to the heat disc 500 near one end of the mounting groove 201. The cooperating member 212 is connected to the mounting member 211 and is in abutment with the second surface of the main body 20 away from the mounting groove 201, so as to clamp the main body 20 together with the heat disc 500.

[0051] In some embodiments, referring to Figure 5 and Figure 6 The cooperating member 212 comprises a connecting portion 213 and an abutment portion 214. The connecting portion 213 is connected to the mounting member 211, and the abutment portion 214 is in abutment with the second surface.

[0052] It can be understood that the specific styles of the mounting member 211 and the cooperating member 212 are not limited. For example, the mounting member 211 is a threaded column, the cooperating member 212 is a screw, and the screw comprises a threaded column and a nut connected to one end of the threaded column. The threaded column is used to threadedly connect with the threaded column, and the nut is used to abut against the second surface and clamp the main body 20 together with the heat disc 500. When the abutment portion 214 is in abutment with the second surface, the abutment portion 214 is at least partially located in the projection area and can exert a force on the temperature sensing bag 300 assembled in the mounting groove 201.

[0053] In some embodiments, referring to Figure 5 and Figure 6 The mounting hole 204 is arranged near the edge of the mounting groove 201 and is in communication with the mounting groove 201. In this way, the mounting hole 204 can shorten the distance between the abutment portion 214 and the projection area, which is beneficial to saving the manufacturing cost of the abutment portion 214.

[0054] In some embodiments, referring to Figure 5 and Figure 6 The fixing device 200 further comprises a buckling portion 22. The buckling portion 22 is connected to any one or both of the two groove side walls 202 of the mounting groove 201 and is used to realize the assembly of the temperature sensing bag 300.

[0055] It can be understood that the specific arrangement of the buckling portion 22 is not limited. In some embodiments, referring to Figures 1 to 3 At least two buckling portions 22 are formed on any one of the two groove side walls 202 and protrude in the second direction. All the buckling portions 22 are arranged in the first direction and are spaced apart from each other. The ends of all the buckling portions 22 protruding in the second direction are spaced apart from the other groove side wall 202. The buckling portion 22 is made of an elastic material. All the buckling portions 22 are spaced apart above the groove bottom wall 203 of the mounting groove 201, and all the buckling portions 22 and the groove bottom wall 203 jointly form a limiting space for mounting the temperature sensing bag 300.

[0056] For the convenience of understanding, define two slot side walls 202 as a first slot side wall 202 and a second slot side wall 202. When the first slot side wall 202 has at least two buckling portions 22 protruding therefrom, the ends of all buckling portions 22 protruding in the second direction are spaced apart from the second slot side wall 202, and the gap formed between the ends of all buckling portions 22 and the second slot side wall 202 forms a communication port in communication with the limiting space. The buckling portion 22 can deform under external force, thereby increasing or decreasing the size of the communication port.

[0057] When assembling the temperature sensing bag 300, the temperature sensing bag 300 will contact and press the buckling portion 22, causing the buckling portion 22 to deform to increase the size of the communication port, so that the temperature sensing bag 300 can enter the limiting space through the communication port. After the temperature sensing bag 300 enters the limiting space, the buckling portion 22 will recover to its original state under the action of its own elastic force, and the communication port will recover to its original size. In this way, the temperature sensing bag 300 that has entered the limiting space cannot escape from the recovered communication port, and the buckling portion 22 prevents the temperature sensing bag 300 in the limiting space from escaping, thereby ensuring the stability of the assembly of the temperature sensing bag 300.

[0058] In addition, all buckling portions 22 are spaced apart from each other in the first direction, so that after the temperature sensing bag 300 enters the limiting space, all buckling portions 22 can cooperate with each other to uniformly limit the temperature sensing bag 300 in the first direction, and ensure the force balance of the temperature sensing bag 300, thereby improving the stability of the assembly of the temperature sensing bag 300.

[0059] Further, the space between any two adjacent buckling portions 22 in the first direction can accommodate the temperature sensing portion of the temperature sensing bag 300. In this way, after the temperature sensing bag 300 and the fixing device 200 are assembled, the surface of the fixing device 200 provided with the mounting groove 201 is attached to the heating disc 500, and the detachable connection between the fixing device 200 and the heating disc 500 is achieved. In this way, the heating disc 500 can seal the mounting groove 201, and the temperature sensing portion protruding from the mounting groove 201 can be attached to the heating disc 500 to detect the water temperature in the kettle.

[0060] It should be further noted that the size of the communication port when the buckling portion 22 is deformed is smaller than the size of the temperature sensing bag 300.

[0061] In other embodiments, please refer to Figures 1 to 3, two slot side walls 202 are formed with at least one buckling part 22 protruding in the second direction, all buckling parts 22 on the same slot side wall 202 are arranged in the first direction and spaced from each other, and the ends of all buckling parts 22 on the same slot side wall 202 protruding in the second direction are spaced from the other slot side wall 202. One buckling part 22 on one of the two slot side walls 202 is arranged in the first direction and spaced from another buckling part 22 on the other slot side wall 202. The buckling part 22 is made of elastic material. All buckling parts 22 are spaced above the groove bottom wall 203 of the mounting groove 201, and all buckling parts 22 and the groove bottom wall 203 jointly form a limiting space for mounting the temperature bag 300.

[0062] For ease of understanding, the number of buckling parts 22 is two in the embodiment, and the two slot side walls 202 are defined as the first slot side wall and the second slot side wall, and the two buckling parts 22 are defined as the first buckling part and the second buckling part. The first buckling part and the second buckling part are respectively protrudingly arranged on the first slot side wall and the second slot side wall. The end of the first buckling part protruding in the second direction is spaced from the second slot side wall to form a first gap, the end of the second buckling part protruding in the second direction is spaced from the first slot side wall to form a second gap, and the first gap and the second gap jointly form a communication port in communication with the limiting space. The buckling part 22 can be deformed under the action of external force, thereby increasing or reducing the communication port.

[0063] When the temperature bag 300 is assembled, the temperature bag 300 contacts and presses the first buckling part and the second buckling part, so that the first buckling part and the second buckling part are deformed to increase the communication port, so that the temperature bag 300 can enter the limiting space through the communication port. After the temperature bag 300 enters the limiting space, the first buckling part and the second buckling part restore to the original state under the action of their own elastic force, and the communication port restores to the original size. In this way, the temperature bag 300 in the limiting space cannot be taken out from the restored communication port, and the buckling part 22 prevents the temperature bag 300 in the limiting space from being taken out, so as to ensure the stability of the assembly of the temperature bag 300.

[0064] In addition, the first buckling part and the second buckling part are arranged in the first direction and spaced from each other, so that after the temperature bag 300 enters the limiting space, the first buckling part and the second buckling part can cooperate with each other to uniformly limit the two ends of the temperature bag 300 in the first direction, and ensure the force balance of the temperature bag 300, thereby improving the stability of the assembly of the temperature bag 300.

[0065] Further, the space between the first direction interval of the first and second buckling parts can provide the temperature sensing part of the temperature sensing bag 300 to protrude into the mounting groove 201. In this way, after the assembly of the temperature sensing bag 300 and the fixing device 200 is completed, the surface of the fixing device 200 provided with the mounting groove 201 is attached to the heating disc 500, and the detachable connection of the fixing device 200 and the heating disc 500 is realized. In this way, the heating disc 500 can seal the mounting groove 201, and the temperature sensing part protruding into the mounting groove 201 can be attached to the heating disc 500 to detect the water temperature in the kettle.

[0066] In some embodiments, referring to Figure 4 and Figure 5 , two buckling parts 22 are protruded on each of the two groove side walls 202, the two buckling parts 22 on the same groove side wall 202 are arranged along the first direction and are spaced apart from each other, and the two buckling parts 22 on the two groove side walls 202 are arranged one by one and are spaced apart from each other along the second direction.

[0067] For easy understanding, define the two groove side walls 202 as a first groove side wall 202 and a second groove side wall 202, define the two buckling parts 22 on the first groove side wall 202 as a first buckling part and a second buckling part, and define the two buckling parts 22 on the second groove side wall 202 as a third buckling part and a fourth buckling part, then the first buckling part and the third buckling part are arranged correspondingly and are spaced apart from each other along the second direction to form a first gap, the second buckling part and the fourth buckling part are arranged correspondingly and are spaced apart from each other along the second direction to form a second gap, and the first gap and the second gap jointly form a communication port in communication with the limiting space.

[0068] When assembling the temperature sensing bag 300, the temperature sensing bag 300 will contact and press the first and second buckling parts, so that the first and second buckling parts are deformed to increase the size of the communication port, so that the temperature sensing bag 300 can enter the limiting space through the communication port. After the temperature sensing bag 300 enters the limiting space, the first and second buckling parts will restore to the original state under the action of their own elastic force, and the communication port will also restore to the original size. In this way, the temperature sensing bag 300 in the limiting space cannot be taken out from the restored communication port, and the buckling part 22 prevents the temperature sensing bag 300 in the limiting space from being taken out, so as to ensure the stability of the assembly of the temperature sensing bag 300.

[0069] In addition, after the temperature sensing bag 300 enters the limiting space, the cooperation of the first and third buckling parts and the cooperation of the second and fourth buckling parts can uniformly limit the two ends of the temperature sensing bag 300 along the first direction, and ensure the force balance of the temperature sensing bag 300; and the first and third buckling parts can limit the two sides of the temperature sensing bag 300 at the same position along the second direction, thereby further improving the stability of the assembly of the temperature sensing bag 300.

[0070] Further, the space between the first and third snap-fit portions and the space between the second and fourth snap-fit portions are spaced apart in the first direction to allow the temperature sensing portion of the temperature sensing bag 300 to protrude into the mounting groove 201. In this way, after the temperature sensing bag 300 is assembled with the fixing device 200, the surface of the fixing device 200 having the mounting groove 201 is attached to the heating disc 500, and the detachable connection between the fixing device 200 and the heating disc 500 is achieved. In this way, the heating disc 500 can seal the mounting groove 201, and the temperature sensing portion protruding into the mounting groove 201 can be attached to the heating disc 500 to detect the temperature of the water in the kettle.

[0071] In some embodiments, referring to Figure 5 and Figure 6 , the end of the snap-fit portion 22 protruding in the second direction and away from the groove bottom wall 203 is formed with an inclined surface 221, and the inclined surface 221 is inclined towards the groove bottom wall 203.

[0072] It can be understood that the inclined surface 221 can guide the assembly of the temperature sensing bag 300, and the inclined surface 221 can reduce the thickness of the end of the snap-fit portion 22 protruding in the second direction, thereby reducing the force required to deform the snap-fit portion 22, to facilitate user use.

[0073] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.

[0074] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these are within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
