Description

Technical Field

[0001] This application relates to the field of household appliances, and more particularly to a base and a liquid heating container. Background Technology

[0002] Liquid heating containers typically consist of a base and a vessel placed on the base. The base is used to heat the liquid inside the vessel. In existing technology, liquid heating containers lack a liquid level detection function. If the base continues to heat the vessel when the liquid level is too low, the vessel is prone to cracking due to dry burning, posing a certain safety hazard. Utility Model Content

[0003] This application provides a base and a liquid heating container that can solve the problem of easy dry burning of the kettle body in the prior art.

[0004] This application provides a base, comprising: a seat body for placing a kettle body of a liquid heating container, the seat body being provided with a mounting portion; a detection device including a liquid level detection component and an elastic element, the liquid level detection component being used to detect the liquid level in the kettle body, and the two ends of the elastic element being fixedly connected to the liquid level detection component and the mounting portion respectively along the radial direction of the base, so that the liquid level detection component is movably mounted on the mounting portion; when the kettle body is placed on the seat body, the elastic element is in a compressed state, and the liquid level detection component can be tightly attached to the side wall of the kettle body under the action of the elastic element.

[0005] In the above solution, the liquid level detection component is used to detect the liquid level inside the kettle, realizing the liquid level detection function of the liquid heating container. This allows users to easily monitor the liquid level inside the kettle, reducing the risk of dry burning and improving the safety of the liquid heating container. When the kettle is placed on the base, the liquid level detection component can compress the elastic element under the action of the kettle, putting the elastic element in a compressed state. At this time, the elastic element can apply pressure to the liquid level detection component, ensuring that the liquid level detection component can fit tightly against the side wall of the kettle under the action of the elastic element. This helps to improve the detection accuracy and the accuracy of the detection results.

[0006] In one possible design, the base further includes a heating plate and a control board, both of which are mounted on the base body. The heating plate is electrically or signal-connected to the control board. The liquid level detection assembly includes a liquid level detection element for detecting the liquid level inside the kettle body. The liquid level detection element is electrically or signal-connected to the control board.

[0007] In the above solution, the control board can stop the heating plate when the liquid level in the kettle is too low, thereby realizing automatic control of the liquid heating container, playing a role in preventing dry burning, thus preventing the glass kettle body from cracking, and improving the safety of the liquid heating container.

[0008] In one possible design, the liquid level detection assembly further includes a housing having a receiving cavity, in which the liquid level detection element is installed.

[0009] In the above solution, the housing can provide a seal and protection for the liquid level detection, reducing the risk of damage to the liquid level detection component and helping to extend its service life.

[0010] In one possible design, the mounting part is provided with a mounting bracket, and along the radial direction of the base, both ends of the elastic member are fixedly connected to the housing and the mounting bracket respectively; the housing and / or the mounting bracket are provided with a limiting groove, and at least a portion of the elastic member is accommodated in the limiting groove.

[0011] In the above scheme, the mounting bracket is used to install the testing device. The limiting groove can limit the elastic element in the radial and circumferential directions, which helps to improve the installation stability of the elastic element. When both the housing and the mounting bracket are provided with limiting grooves, the two ends of the elastic element can be limited respectively, thereby further improving the installation stability of the elastic element.

[0012] In one possible design, the mounting bracket is provided with a groove extending radially along the base; the housing is provided with a slider that slides in engagement with the groove.

[0013] In the above scheme, when the liquid level detection component is squeezed by the elastic element under the action of the vessel body, and when the elastic element pushes the liquid level detection component to reset, the slider can slide along the slide groove, which helps to improve the stability of the liquid level detection component during the movement process.

[0014] In one possible design, the receiving cavity is provided with a mounting groove, and the liquid level detection component is fixed in the mounting groove; the receiving cavity is also provided with abutment portions distributed circumferentially along the mounting groove; the liquid level detection assembly further includes a waterproof component, which is installed in the receiving cavity and is sealed with the abutment portions.

[0015] In the above solution, the mounting groove can limit the liquid level detection component in the circumferential direction, thereby improving the installation stability of the liquid level detection component. The waterproof component can cover the opening of the mounting groove and seal the liquid level detection component located in the mounting groove, preventing liquid or vapor from entering the mounting groove, thereby reducing the risk of liquid or vapor corrosion of the liquid level detection component and helping to extend the service life of the liquid level detection component.

[0016] In one possible design, the housing includes a first housing and a second housing, the second housing being snapped onto the first housing, the first housing and the second housing forming the receiving cavity; the waterproof component is held between the abutment portion and the second housing along the radial direction of the base.

[0017] In the above solution, the abutment part and the second shell together restrict the radial movement of the waterproof component along the base, which helps to improve the installation stability of the waterproof component and thus improve the sealing effect of the waterproof component.

[0018] In one possible design, the detection device further includes a temperature sensing element along the radial direction of the base, the temperature sensing element being mounted on the surface of the housing away from the mounting portion; the temperature sensing element is used to detect the temperature of the liquid inside the vessel, and the temperature sensing element is electrically or signal-connected to the control board.

[0019] In the above scheme, when the kettle body is placed on the base, the temperature detection device is used to detect the temperature of the liquid inside the kettle body. The control board can receive the signal from the temperature detection device and compare it with the preset temperature. When the temperature of the liquid inside the kettle body reaches the preset temperature, the control board can output a signal to the heating plate to control the heating plate to stop heating, avoid the heating plate from continuously heating, and help reduce the energy consumption of the liquid heating container.

[0020] In one possible design, the housing is provided with a slot extending radially along the base; the temperature sensing element is provided with a plug extending radially along the base, at least a portion of the plug extending into the slot and being fixedly connected to the slot.

[0021] In the above solution, the pre-positioning of the housing and the temperature sensing element can be achieved through the cooperation of the plug and the slot, so as to improve the assembly efficiency between the temperature sensing element and the housing, and also improve the connection strength between the temperature sensing element and the housing, thereby improving the installation stability of the temperature sensing element.

[0022] A second aspect of this application provides a liquid heating container, including a body and a base as described above, wherein the body is placed on the base.

[0023] In the above solution, by setting a liquid level detection component on the base, the liquid level inside the pot can be detected, reducing the risk of dry burning of the liquid heating container and thus improving the safety of the liquid heating container.

[0024] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0056] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0057] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0058] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0059] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0060] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0061] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0062] This application provides a liquid heating container, such as... Figure 1 As shown, the liquid heating container includes a body 20 and a base 10 for placing the body 20, as... Figure 2 and Figure 3 As shown, the base 10 includes a seat 1 and a heating plate 3 disposed on the seat 1. The kettle body 20 is used to hold liquid. When boiling water, the kettle body 20 can be placed on the surface of the heating plate 3, which heats the liquid inside the kettle body 20. The base 10 also includes a detection device 2, which, in conjunction with... Figure 4 As shown, the detection device 2 includes a liquid level detection component 21 and an elastic element 22. The liquid level detection component 21 is used to detect the liquid level inside the kettle body 20, realizing the liquid level detection function of the liquid heating container. The liquid level detection component 21 can provide real-time feedback on the liquid level height inside the kettle body 20. Users can use the detection results of the liquid level detection component 21 to understand the liquid level inside the kettle body 20. If the liquid level inside the kettle body 20 is too low, users can remove the kettle body 20 in time or add water to the kettle body 20 to reduce the risk of dry burning of the liquid heating container and improve the safety of the liquid heating container. The base 1 is provided with a mounting part 11, and the mounting part 11 is provided with a mounting cavity 111. Along the radial direction X of the base 10, both ends of the elastic element 22 are fixedly connected to the liquid level detection component 21 and the mounting part 11, respectively, so that the liquid level detection component 21 is movably mounted in the mounting cavity 111. When the vessel body 20 is placed on the base 1, the liquid level detection component 21 can squeeze the elastic element 22 towards the inside of the mounting cavity 111 under the action of the vessel body 20, so that the elastic element 22 is in a compressed state. At this time, the elastic element 22 can apply pressure to the liquid level detection component 21, thereby ensuring that the liquid level detection component 21 can be tightly attached to the side wall of the vessel body 20 under the action of the elastic element 22, which is beneficial to improving the detection accuracy and the accuracy of the detection results of the liquid level detection component 21.

[0063] In this embodiment, the elastic element 22 can be a compression spring or a sheet, or other elastic structure; this embodiment does not limit this. The following description uses a compression spring as an example to illustrate the structure of the detection device 2.

[0064] The base 10 also includes a control board, which is installed inside the base 1. The heating plate 3 is electrically or signal-connected to the control board, and the control board can control the heating plate 3 to turn on or off. Figure 4As shown, the liquid level detection component 21 includes a liquid level detection element 211, which is used to detect the liquid level inside the vessel body 20. Specifically, the liquid level detection element 211 can be a non-contact liquid level sensor. This embodiment uses a capacitive liquid level sensor as an example to explain the working principle of the liquid level detection element 211. Specifically, when the liquid level inside the vessel body 20 is different, the liquid level detection element 211 will generate different capacitance signals. The vessel body 20 can have a preset minimum liquid level. The liquid level detection element 211 is electrically or signal-connected to the control board. The control board can receive the capacitance signal from the liquid level detection element 211 and compare it with the capacitance signal of the preset liquid level. Based on the comparison result, it determines whether the liquid level inside the vessel body 20 is too low. When the liquid level inside the vessel body 20 is lower than the preset liquid level, the control board can output a signal to the heating plate 3 to control the heating plate 3 to stop heating, thereby realizing automatic control of the liquid heating container, preventing dry burning, and thus preventing the glass vessel body 20 from cracking, which helps improve the safety of the liquid heating container. Similarly, when the kettle body 20 is not placed on the base 1, the control board can also control the heating plate 3 to stop heating by changing the capacitance signal of the liquid level detection element 211, thereby preventing the base 10 from being in an empty-burning state.

[0065] Combination Figure 5 As shown, the liquid level detection assembly 21 also includes a housing 212, which has a receiving cavity 212a. The liquid level detection element 211 is installed in the receiving cavity 212a. The housing 212 provides a seal and protection for the liquid level detection element 211, reducing the risk of damage to the liquid level detection element 211 and thus improving its service life. Specifically, the housing 212 includes a first housing 2121 and a second housing 2122. The second housing 2122 is fastened to the first housing 2121, and the first housing 2121 and the second housing 2122 form the receiving cavity 212a. A mounting groove 212c is provided in the receiving cavity 212a. The liquid level detection element 211 is fixed in the mounting groove 212c. The mounting groove 212c can limit the liquid level detection element 211 in the circumferential direction, thereby improving the installation stability of the liquid level detection element 211.

[0066] The receiving cavity 212a is also provided with abutment portions 212d distributed circumferentially along the mounting groove 212c. The liquid level detection assembly 21 also includes a waterproof component 213, which is installed in the receiving cavity 212a and seals with the abutment portions 212d. That is, the waterproof component 213 can cover the opening of the mounting groove 212c and seal the liquid level detection component 211 located in the mounting groove 212c, preventing liquid or vapor from entering the mounting groove 212c, thereby reducing the risk of liquid or vapor corrosion of the liquid level detection component 211 and improving its service life. Along the radial direction X of the base 10, the waterproof component 213 is clamped between the abutment portions 212d and the second housing 2122. The abutment portions 212d and the second housing 2122 together restrict the movement of the waterproof component 213 along the radial direction X of the base 10, which helps to improve the installation stability of the waterproof component 213 and thus improves the sealing effect of the waterproof component 213.

[0067] In one specific implementation, such as Figure 2 As shown, the mounting part 11 is provided with a mounting bracket 4, which is fixedly installed in the mounting cavity 111. Along the radial direction X of the base 10, both ends of the elastic member 22 are fixedly connected to the second housing 2122 and the mounting bracket 4, respectively. Figure 4 and Figure 5 As shown, the second housing 2122 and / or the mounting bracket 4 are provided with limiting grooves 41. At least a portion of the elastic element 22 is accommodated within the limiting grooves 41. The limiting grooves 41 can limit the elastic element 22 in the radial and circumferential directions, which helps to improve the installation stability of the elastic element 22. When both the second housing 2122 and the mounting bracket 4 are provided with limiting grooves 41, both ends of the elastic element 22 can be limited respectively, thereby further improving the installation stability of the elastic element 22.

[0068] Combination Figure 6 As shown, the mounting bracket 4 is provided with a groove 42 extending radially X along the base 10, and the first housing 2121 is provided with a slider 212b, at least a portion of which extends into the groove 42. When the liquid level detection component 21 is pressed against the elastic member 22 by the body 20, and when the elastic member 22 pushes the liquid level detection component 21 to reset, the slider 212b can slide along the groove 42, which helps to improve the stability of the liquid level detection component 21 during movement. Specifically, along the height direction Z of the base 10, the mounting bracket 4 can be provided with two grooves 42 of different heights, and the first housing 2121 can also be provided with two sliders 212b of different heights. Furthermore, grooves 42 can be provided on both sides of the length direction Y of the mounting bracket 4, and sliders 212b can also be provided on both sides of the first housing 2121, thereby further improving the movement stability of the liquid level detection component 21.

[0069] In one specific embodiment, the detection device 2 further includes a temperature detection element 214. Along the radial direction X of the base 10, the temperature detection element 214 is mounted on the side surface of the first housing 2121 away from the mounting portion 11 and is electrically or signal-connected to the control board. When the kettle body 20 is placed on the base 1, the temperature detection element 214 is used to detect the temperature of the liquid inside the kettle body 20. Specifically, the temperature detection element 214 can be a temperature sensor. The control board can receive the signal from the temperature detection element 214 and compare it with a preset temperature. When the liquid temperature inside the kettle body 20 reaches the preset temperature, the control board can output a signal to the heating plate 3 to control the heating plate 3 to stop heating, avoiding continuous heating of the heating plate 3, which helps to reduce the energy consumption of the liquid heating container.

[0070] like Figure 6 As shown, the first housing 2121 is provided with a slot 212e extending radially X along the base 10, and the temperature sensing element 214 is provided with a plug portion 214a extending radially X along the base 10. At least a portion of the plug portion 214a extends into the slot 212e and is fixedly connected to the slot 212e. The cooperation between the plug portion 214a and the slot 212e can realize the pre-positioning of the first housing 2121 and the temperature sensing element 214, thereby improving the assembly efficiency between the temperature sensing element 214 and the first housing 2121, and also improving the connection strength between the temperature sensing element 214 and the first housing 2121, thereby improving the installation stability of the temperature sensing element 214.
