Description

Technical Field

[0001] This utility model belongs to the field of home appliances, and more specifically, it relates to an electric kettle cooking status detection module and an electric kettle. Background Technology

[0002] Electric kettles are common household appliances. As people's requirements for their use increase, in addition to the conventional heating function, electric kettles also need to have a heat preservation function or an anti-dry-boil function.

[0003] To achieve heat preservation or anti-dry-boil functions, it is inevitable to monitor the state inside the kettle, such as water level and temperature. To avoid affecting the integrity of the kettle's inner wall, existing technologies use different detection modules that contact the side of the kettle body to collect signals, depending on the monitoring requirements. For better fit with the side of the kettle body, the detection modules typically use a flexible contact method. However, this method makes it difficult to observe the contact position, and whether it is fully in contact often requires the user to judge by feel and experience, or a separate indicator module to provide feedback, making operation inconvenient. Furthermore, detection modules with a longer protrusion are easily damaged by bumps and knocks when the kettle is placed from top to bottom. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides an electric kettle cooking status detection module, which solves the technical problems in the prior art where the user's ability to trigger the detection module is insufficient and the detection module is easily damaged when the kettle is placed.

[0005] To achieve the above objectives, this utility model is accomplished by the following specific technical means:

[0006] An electric kettle cooking status detection module includes a housing, a signal acquisition component, an elastic connection component, and a detection abutment. The detection abutment is connected to the housing via the elastic connection component, allowing it to move along a telescopic direction. The signal acquisition component is disposed within the housing and has a acquisition end connected to the outer end face of the detection abutment. A guide slope is provided at the corner edge of one side of the outer end face of the detection abutment, and the extension direction of the guide slope forms an angle β with the telescopic direction, where β is less than 90°.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] When placing the kettle, the user can press it against the end face where the detection module is located and slide it into place in the direction perpendicular to the extension and retraction direction of the detection contact. This ensures that the kettle is in contact with the detection contact throughout the sliding process. The guide slope design allows the kettle to apply a component force along the extension and retraction direction to the detection contact when it contacts it, ensuring a smooth transition and reducing the impact force when the kettle contacts the detection contact, thus preventing damage to the detection module.

[0009] Furthermore, the middle part of the housing is a receiving cavity, and the detection abutment is sleeved in the receiving cavity. The sleeved arrangement can effectively prevent the detection abutment from flipping over during the extension and retraction process, which would cause its detection end face to fail to fit with the pot body.

[0010] Furthermore, the housing is provided with a guide groove extending along the telescopic direction, and the detection abutment is provided with a guide post adapted to the guide groove, providing stable and smooth support for the telescopic movement of the elastic abutment.

[0011] Furthermore, there are two or more guide grooves, which are arranged on both sides of the housing; and there are two or more guide posts of the probed abutment, which are symmetrically arranged to effectively improve the guiding effect.

[0012] Furthermore, the outer end of the guide groove is provided with a first engagement guide slope in the shape of a flared opening, and the end of the guide post is provided with a second engagement guide slope with an inclination direction opposite to that of the first engagement guide slope. Furthermore, there are two or more signal acquisition components, and the detection abutment is provided with isolation ribs, which divide the inner side of its outer end face into independent acquisition areas adapted to the acquisition ends of each acquisition component, thus avoiding signal interference between different acquisition components.

[0013] This utility model also provides an electric kettle using the aforementioned electric kettle cooking status detection module, comprising a kettle body and a base. The upper end face of the base is provided with a limiting barrier, and the limiting barrier and the upper end face of the base form a kettle body placement cavity with at least an upper opening. The kettle body can be detachably placed in the kettle body placement cavity. The electric kettle cooking status detection module is disposed on the inner wall of the limiting barrier, and its extension direction is perpendicular to the extension direction of the limiting barrier. The guide slope is located at the corner edge of the upper part of the outer end face of the detection contact member.

[0014] Furthermore, the outer end face of the detection contact is an arc-shaped structure adapted to the body of the pot, ensuring a good fit and improving the detection accuracy of the detection module.

[0015] Furthermore, the bottom of the kettle body is provided with an elastic washer, and the elastic washer is provided with a detection notch corresponding to the position of the detection abutment, so that the detection abutment can be as close as possible to the bottom of the kettle body, making the detection more accurate.

[0016] Furthermore, the height of the top of the limiting barrier gradually decreases from one end to the other. The electric kettle cooking status detection module is set on the inner wall of the higher side of the limiting barrier. Since there is a large space available there, it is more reasonable to set it here to facilitate the installation of the detection module. Attached Figure Description

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example

[0025] See Figures 1 to 3An electric kettle cooking status detection module includes a housing 1, a signal acquisition component 2, an elastic connection component 3, and a detection abutment 4. The detection abutment 4 is connected to the housing 1 via the elastic connection component 3, allowing the detection abutment 4 to move along a telescopic direction X. The signal acquisition component 2 is disposed inside the housing 1 and has a acquisition end 201 connected to the outer end face of the detection abutment 4. A guide slope 401 is provided at the corner edge of one side of the outer end face of the detection abutment 4, and the extension direction Y of the guide slope 401 forms an angle β with the telescopic direction X, where β is less than 90°.

[0026] To adapt to different application scenarios, the electric kettle cooking status detection module can be placed horizontally on the kettle base to detect the cooking status of the kettle from the bottom; alternatively, it can be installed on a stop component extending upwards from the side of the base to detect the cooking status of the kettle from the side. In both methods, the kettle body first contacts the guide slope 401 of the detection abutment 4 during the sliding process. This ensures that the kettle body applies a component force along the extension direction of the detection abutment 4 when it contacts the detection abutment 4, guaranteeing a smooth transition and maintaining a close fit. It also reduces the impact force when the kettle body contacts the detection abutment 4, preventing damage to the detection module.

[0027] To make the detection module more compact, the middle part 1 of the housing is a receiving cavity 101, and the detection abutment 4 is sleeved inside the receiving cavity 101. At the same time, the nesting method can effectively prevent the detection abutment 4 from flipping over during the extension and retraction process, which would prevent its detection end face from fitting against the pot body.

[0028] Existing electric kettles generally need to simultaneously possess both anti-dry-boil and temperature control functions. These two functions require different detection devices to achieve. Therefore, the signal acquisition component 2 includes a temperature acquisition component 201 and a liquid level acquisition component 202. The detection contact 4 is provided with an isolation rib 402, which divides the inner side of its outer end face into independent temperature acquisition area 4A and liquid level acquisition area 4B to avoid signal interference between different acquisition components. The liquid level acquisition component 202 is a capacitive sensing component, and its acquisition end can be located on the rear side of the front end face of the detection contact 4. The temperature acquisition component can be a modular NTC thermistor, with its front end 201A penetrating through the side wall of the front end face of the detection contact 4, or it can be a separate temperature acquisition component, with its acquisition end being a metal heat-conducting surface 201A, which needs to penetrate through the side wall of the front end face of the detection contact 4.

[0029] The housing 1 is provided with a guide groove 102 extending along the telescopic direction, and the detection abutment 4 is provided with a guide post 401 adapted to the guide groove 102. There are two or more guide grooves 102, which are symmetrically arranged on both sides of the housing 1. The guide post 401 of the detection abutment 4 is adapted to provide stable and smooth support for the telescopic movement of the elastic abutment 4.

[0030] As a preferred embodiment, the outer end of the guide groove 102 is provided with a first engagement guide slope 102A in the shape of a flared opening, and the end of the guide post 401 is provided with a second engagement guide slope 401A with an inclination direction opposite to that of the first engagement guide slope 102A. When both the housing 1 and the detection abutment member 4 are plastic parts, the cooperation between the first engagement guide slope 102A and the second engagement guide slope 401A can better utilize their elasticity to complete the combination. Example

[0031] An electric kettle using the aforementioned electric kettle cooking status detection module includes a kettle body 11 and a base 12. A limiting barrier 13 is provided around the upper end face of the base 11, and the limiting barrier 13 and the upper end face 12A of the base form a kettle body placement cavity 12B with at least an upper opening. The kettle body 11 can be detachably placed within the kettle body placement cavity 12B. The electric kettle cooking status detection module 14 is disposed on the inner wall of the limiting barrier 13, and its extension direction X is perpendicular to the extension direction of the limiting barrier 13. The guide inclined surface 401 is located at the corner edge of the upper part of the outer end face of the detection contact member 4. The outer end face of the detection contact member 4 has an arc-shaped structure adapted to the kettle body 11, ensuring a good fit and improving the detection accuracy of the cooking status detection module 14. The bottom of the pot body 11 is provided with an elastic washer 11A, and the elastic washer 11A is provided with a detection notch (not shown in the figure) corresponding to the position of the detection abutment, so that the detection abutment 4 can be as close as possible to the bottom of the pot body 11, making the detection more accurate.

[0032] The top of the limiting barrier 13 gradually decreases in height from one end to the other. The electric kettle cooking status detection module 14 is set on the inner wall of the higher side of the limiting barrier 13. Since there is a large space available at this location, it is more reasonable to set it here to facilitate the installation of the detection module.

[0033] Based on the inclined setting of the limiting barrier 13, when the user places the kettle body 11, the bottom of the kettle body 11 can first abut against the top of the higher side of the limiting barrier 13, and then slide down smoothly. The bottom of the kettle body 11 first touches the guide slope 401, so that the electric kettle cooking status detection module 14 can retract smoothly until the kettle body 11 is placed in place, effectively ensuring that the electric kettle cooking status detection module 14 fits tightly against the side wall of the kettle body.

[0034] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
