Abstract
Description
[Technical Field]
[0001] This utility model relates to the field of switch technology, and in particular to a switch device for a temperature sensing component of a milk frother. [Background Technology]
[0002] With technological innovation, switches are playing an increasingly important role in daily life, work, and entertainment. They have evolved from initial pull-cord switches, thumb switches, and rocker switches to touchscreen switches and smart switches. With the popularization of smart homes, people's demands for switches have expanded beyond just light control; they have higher requirements for the entire home environment, which has greatly promoted the development of smart display touch switches.
[0003] However, existing technologies use two separate components: a sensor and a microswitch. In use, these two independent components are directly mounted on the electrical appliance being used. The electrical appliances include small appliances such as kettles, milk frothers, coffee makers, and bottle warmers.
[0004] By directly mounting two separate sensor components and a micro switch component onto the electrical appliance being used, the switch component can easily occupy a large area of the small appliance, making the design more complex, the installation and operation more complicated, and the processing steps more troublesome, thus increasing design and production costs and reducing production efficiency. [Utility Model Content]
[0005] In view of this, the technical problem to be solved by the utility model application in this case is to provide a temperature sensing component switch device for a milk frother that can not only reduce production costs, improve production efficiency, and reduce the volume occupied, but also has the advantages of easy installation and processing.
[0006] To address the aforementioned technical problems, the present invention provides a temperature-sensing component switch device for a milk frother, comprising a switch base, a micro switch, and a milk frother body; the upper end of the switch base is provided with a spring button mechanism for controlling the opening or closing action of the switch, and the lower end of the switch base is provided with a micro switch mounting bracket for housing and fixing the micro switch; the spring button mechanism includes a button support cylinder, a sensor assembly installed inside the button support cylinder, and a spring installed on the outer periphery of the bottom of the button support cylinder.
[0007] The sensor assembly includes a sensor placed directly inside the button support cylinder, a power cord located at the lower end of the sensor, and a connection socket located at the other end of the power cord.
[0008] The micro switch includes a micro switch body and a micro switch lever that can move up and down on the micro switch body.
[0009] In use, when the spring button mechanism is pressed downwards under the weight of the milk frother, the button support cylinder is also pressed downwards, causing the button support cylinder, which is located on a portion of the protruding aluminum heating surface, and the sensor assembly located inside the button support cylinder to move downwards simultaneously. At the same time, the bottom end of the button support cylinder is pressed downwards, causing the micro switch lever to be pressed downwards. At this time, the button support cylinder and the sensor assembly located inside are flush with the heating plate surface of the milk frother, and the micro switch is in the on state. At this time, the milk frother is powered on and enters the working state.
[0010] When the sensor in the button bracket cylinder senses that the water temperature inside the milk frother has reached the set temperature, the sensor in the button bracket cylinder transmits the temperature signal to the control board of the milk frother through the power cord, and the milk frother automatically stops heating and enters the heat preservation state.
[0011] When the main body of the milk frother is removed from the base, the external force on the spring button mechanism disappears. Under the elastic force of the spring, the button support cylinder automatically springs back to its original position. The upper part of the button support cylinder protrudes from the heating plate plane of the milk frother, while the lower part of the button support cylinder moves upward away from the micro switch lever. The micro switch lever returns to its original position, and the micro switch is in the off state. At this time, the main body of the milk frother is in a power-off state and the main body of the milk frother is in a stopped working state.
[0012] Further defined, the switch base includes a micro switch mounting bracket, a button cylinder vertically disposed at the upper end of the micro switch mounting bracket, a cylindrical receiving cavity disposed inside the button cylinder, a sensor assembly disposed inside the cylindrical receiving cavity, and a micro switch receiving cavity disposed inside the micro switch mounting bracket for accommodating and fixing the micro switch; the cylindrical receiving cavity and the micro switch receiving cavity are interconnected; switch mounting plates for fixing are respectively disposed at both ends of the micro switch mounting bracket; and switch fixing posts and snap-fit bending bodies for fixing the micro switch are disposed inside the micro switch receiving cavity.
[0013] Further defined, the button support tube includes a support tube body that is larger at the top and smaller at the bottom, an unclosed component receiving cavity disposed inside the support tube body for accommodating sensor components, an annular baffle disposed at the upper end of the support tube body, a protruding corner body disposed on the annular baffle, a notch groove disposed on one side of the lower end of the support tube body, and an annular bottom plate disposed at the bottom of the notch groove.
[0014] The beneficial technical effects of this utility model are as follows: the upper end of the switch base is provided with a spring button mechanism for controlling the opening or closing action of the switch, and the lower end of the switch base is provided with a micro switch fixing bracket for accommodating and fixing the micro switch.
[0015] The spring button mechanism includes a button support cylinder, a sensor assembly installed inside the button support cylinder, and a spring installed on the bottom periphery of the button support cylinder; the sensor assembly includes a sensor placed directly inside the button support cylinder, a power cord located at the lower end of the sensor, and a connection socket located at the other end of the power cord.
[0016] In use, the spring-loaded button mechanism located inside the upper part of the switch base works in conjunction with the microswitch located inside the lower part of the switch base to achieve the opening and closing actions of the switch. This solves the drawbacks of the existing technology that requires the installation of two separate sensors and microswitches, which helps to reduce production and design costs, improve production efficiency, and reduce the space occupied.
[0017] Since the spring button mechanism is installed inside the cylindrical receiving cavity at the upper end of the switch base, and the micro switch is installed inside the micro switch receiving cavity at the lower end of the switch base, compared with similar products in the prior art, the switch of this application also has the functions of convenient installation and convenient design.

Detailed Implementation Methods
[0026] In order to make the technical problem to be solved, the technical solution and the beneficial technical effects of this utility model clearer and more complete, the technical solution of this utility model will be further described in detail with reference to the following drawings and embodiments, so as to enable correct understanding. The specific embodiments described herein are only used to explain and illustrate the understanding of the technical solution of this utility model.
[0027] Please refer to Figures 1 to 7 As shown in the figure, the following describes a temperature sensing component switch device for a milk frother, which includes a switch base, a micro switch, a milk frother body, and a spring button mechanism for controlling the opening or closing action of the switch.
[0028] The switch base includes a micro switch mounting bracket 101 disposed at the lower end for housing and fixing a micro switch, a switch cylinder 102 vertically disposed at the upper end of the micro switch mounting bracket 101, a cylindrical receiving cavity 103 disposed inside the switch cylinder 201, and a micro switch receiving cavity 104 disposed inside the micro switch mounting bracket 101 for housing and fixing a micro switch; the cylindrical receiving cavity 103 and the micro switch receiving cavity 104 are interconnected; switch mounting plates 105 for fixing are respectively disposed at both ends of the micro switch mounting bracket 101; a switch fixing post 106 and a snap-fit bending body 107 for fixing the micro switch 2 are disposed inside the micro switch receiving cavity 104.
[0029] The micro switch includes a micro switch body 201 and a flexible micro switch lever 202 disposed on the micro switch body 201.
[0030] The spring button mechanism includes a button support cylinder 301, a sensor assembly installed inside the button support cylinder 301, and a spring 302 installed on the bottom periphery of the button support cylinder 301. The sensor assembly includes a sensor button 303 directly placed inside the button support cylinder 301, a power cord 304 located at the lower end of the sensor 303, and a connection socket 310 located at the other end of the power cord 304. The button support cylinder 301 includes a support cylinder body that is larger at the top and smaller at the bottom, an unclosed component receiving cavity 305 located inside the support cylinder body for accommodating the sensor assembly, an annular baffle 306 located at the upper end of the support cylinder body, a protruding corner 307 located on the annular baffle 306, a notch 308 located on one side of the lower end of the support cylinder body, and an annular base plate 309 located at the bottom of the notch 308.
[0031] During installation, the micro switch is mounted inside the micro switch receiving cavity 104 of the switch base by the combined action of the switch fixing post 106 and the snap-fit bending body 107. The button bracket cylinder 301 is installed inside the cylindrical receiving cavity 103 of the switch base, the sensor assembly is installed inside the button bracket cylinder 301, the sensor 303 is located at the upper end of the button bracket cylinder 301, and the connecting socket 310 is installed at the lower end of the button bracket cylinder 301, with the excess portion placed inside the micro switch receiving cavity 104. The spring 302 is installed between the outer surface of the button bracket cylinder 301 and the inner surface of the cylindrical receiving cavity 103 inside the switch base, and is located at the lower outer part of the annular baffle 309 of the button bracket cylinder 301.
[0032] When in use, when the spring button mechanism is squeezed by the weight of the milk frother, the button support cylinder 301 is squeezed downward, which drives the sensor assembly set inside the button support cylinder 301 to move downward. The bottom end of the button support cylinder 301 squeezes the micro switch rod 202 downward. At this time, the micro switch is in the open state. At this time, the small appliance is in the power-on state and the small appliance is in the working state.
[0033] When the sensor 303 detects that the temperature has been reached, it will connect to the connector 310 via the power cord. The connector 310 will then transmit a signal to the control board to stop the heating.
[0034] When the main body of the milk frother is removed, the external force on the spring button mechanism disappears. Under the elastic force of the spring 302, the button support cylinder 301 moves upward a certain distance to return to its original position. The upper part of the button support cylinder 301 will protrude a certain distance from the heating plate plane of the milk frother, while the lower part of the button support cylinder 301 will automatically spring back to its original position, away from the micro switch lever 202. The micro switch lever 202 returns to its original state, and the micro switch is in the closed state. At this time, the main body of the milk frother is in a power-off state and the main body of the milk frother is in a stopped working state.
[0035] In the above structure, a spring-loaded button mechanism located inside the upper end of the switch base and a microswitch located inside the lower end of the switch base work together to realize the opening and closing actions of the switch. This solves the drawbacks of installing two separate sensors and a microswitch in the prior art, which helps to reduce design and production costs, improve production efficiency, and reduce the space occupied.
[0036] Since the spring button mechanism is installed inside the cylindrical receiving cavity 103 at the upper end of the switch base, and the micro switch is installed inside the micro switch receiving cavity 104 at the lower end of the switch base, it can be seen from the comparison with similar products in the prior art that the switch of this application also has the functions of convenient installation and convenient design.
[0037] The above description, with reference to the accompanying drawings, illustrates preferred embodiments of the utility model in this case, but does not limit the scope of the utility model's technical solution. Any modifications, equivalent substitutions, and improvements made by those skilled in the art without departing from the scope of protection and substantive rights of the utility model's technical solution shall be within the scope of the utility model's technical solution.
