Description

Technical Field

[0001] This utility model relates to the field of electric blanket controller technology, and in particular to a digital temperature-controlled electric blanket controller. Background Technology

[0002] As a core component of electric blankets, digital temperature-controlled electric blanket controllers can precisely adjust the temperature of the electric blanket, providing users with a comfortable and warm experience. This controller typically includes a control circuit, a temperature sensor, a display module, and operation buttons: the control circuit processes signals and controls the heating power; the temperature sensor monitors the electric blanket temperature in real time; the display module shows information such as temperature and operating mode; and the operation buttons allow users to easily set the temperature, switch modes, and perform other operations.

[0003] In practical applications, digital temperature-controlled electric blanket controllers typically require the following structure:

[0004] 1. The main control chip is the core of the controller, responsible for processing the data collected by the temperature sensor and controlling the heating state of the electric blanket according to the preset program;

[0005] 2. The temperature sensor is used to monitor the temperature of the electric blanket in real time and convert the temperature signal into an electrical signal to be transmitted to the main control chip;

[0006] 3. The display module can intuitively display the current temperature setting and working status of the electric blanket, making it convenient for users to operate;

[0007] Currently, to ensure the normal operation of digital temperature-controlled electric blanket controllers and prevent internal components from being damaged by overheating, most controllers have heat dissipation slots on their casings to promote airflow and dissipate heat. Some controllers have protective mesh covers on the surface of the heat dissipation slots to prevent dust, hair, and other debris from entering the controller and affecting the normal operation of the components. Other controllers use cooling fans to assist in heat dissipation, accelerating heat dissipation through forced airflow.

[0008] However, the above-mentioned implementation methods still have the following problems. Traditional protective nets are mostly fixed installations. As the usage time increases, a large amount of dust and debris will accumulate on the protective nets and heat dissipation slots, affecting the heat dissipation effect. However, cleaning requires the use of tools to pry open or remove the protective nets, which is cumbersome and can easily damage the controller. Even if some protective nets are designed to be detachable, additional cleaning tools are still required when cleaning the heat dissipation slots. The process is complicated and it is difficult to guarantee the cleaning effect, which leads to heat accumulation inside the controller, affecting the temperature control accuracy and even posing a safety hazard. In response to this problem, this application proposes a solution: designing a digital temperature-controlled electric blanket controller with a detachable protective net and a cleaning block fixed on it that completes the cleaning of the heat dissipation slots when the protective net is detached. This simplifies the cleaning process, improves cleaning efficiency and effect, and ensures the normal operation of the controller. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a digital temperature-controlled electric blanket controller. It solves the problem that traditional protective nets are mostly fixed installations, and as the usage time increases, a large amount of dust and debris will accumulate on the protective nets and heat dissipation grooves, affecting the heat dissipation effect. However, cleaning requires the use of tools to pry open or remove the protective nets, which is cumbersome and can easily damage the controller. Even if some protective nets are designed to be detachable, additional cleaning tools are required when cleaning the heat dissipation grooves, making the process complicated and difficult to guarantee the cleaning effect.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A digital temperature-controlled electric blanket controller includes a controller body, a protective mesh cover on the lower surface of the controller body, a set of heat dissipation grooves on the lower surface of the controller body, a fixed base fixedly connected to the lower surface of the controller body, a pressing block above the fixed base, a return spring fixedly connected to the upper surface of the pressing block, a limit block fixedly connected to the annular side of the pressing block, a cleaning block fixedly connected to the upper surface of the protective mesh cover, and two rectangular slots on the lower surface of the controller body, both of which are movably connected to the protective mesh cover.

[0012] Preferably, the surface of the pressing block has two arc-shaped grooves, both of which are movably engaged with the fixing seat, and the surface of the protective mesh cover has a limit groove.

[0013] Preferably, the limiting groove is movably engaged with the limiting block, and the cleaning block is movably engaged with a set of heat dissipation grooves.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the protective net cover needs to be disassembled, press the pressing block to move the limiting block fixed to it. The limiting block moves downward and disengages from the protective net cover, opening the limit. At this time, the protective net cover can be slid off for disassembly. The protective net cover is connected through two rectangular slots on the controller body. The rectangular slots have grooves that limit the protective net cover. The detachable protective net cover makes it convenient for users to remove it regularly for cleaning, maintain the ventilation performance of the net cover, and ensure good heat dissipation of the controller body.

[0016] 2. During the disassembly of the protective mesh cover, the cleaning block fixed to it also moves. The cleaning block is engaged in a set of heat dissipation slots. As it moves, it will clean the dust accumulated on the inner wall of the heat dissipation slots and push the dust out. When disassembling the protective mesh cover, the user needs to place the opening of the heat dissipation slots downwards to prevent dust from falling into the controller body. At the same time as the protective mesh cover is removed, the cleaning block can immediately play its role, quickly removing dust and debris from the heat dissipation slots, greatly improving cleaning efficiency and saving the user's time and effort.

[0023] This application provides a digital temperature-controlled electric blanket controller that effectively solves the problems of traditional protective nets being mostly fixed installations, which accumulate a lot of dust and debris on the protective nets and heat dissipation grooves over time, affecting heat dissipation. However, cleaning requires tools to pry open or remove the protective nets, which is cumbersome and can easily damage the controller. Even if some protective nets are designed to be detachable, additional cleaning tools are needed when cleaning the heat dissipation grooves, making the process complicated and difficult to guarantee the cleaning effect. The proposed digital temperature-controlled electric blanket controller features a detachable protective net, and the cleaning block fixed to the net completes the cleaning of the heat dissipation grooves during removal. This simplifies the cleaning process, improves cleaning efficiency and effect, and ensures the normal operation of the controller. Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that traditional protective net covers are mostly fixed installations, and as the usage time increases, a large amount of dust and debris will accumulate on the protective net cover and heat dissipation groove, affecting the heat dissipation effect. However, cleaning requires the use of tools to pry open or remove the protective net cover, which is cumbersome and can easily damage the controller. Even if some protective net covers are designed to be detachable, additional cleaning tools are required when cleaning the heat dissipation groove, making the process complex and difficult to guarantee the cleaning effect. The overall idea is as follows:

A protective mesh cover 2 is provided on the lower surface of the controller body 1. A set of heat dissipation grooves 5 are formed on the lower surface of the controller body 1. A fixing base 4 is fixedly connected to the lower surface of the controller body 1. A pressing block 3 is provided above the fixing base 4. A return spring 10 is fixedly connected to the upper surface of the pressing block 3. A limit block 11 is fixedly connected to the annular side of the pressing block 3. A cleaning block 8 is fixedly connected to the upper surface of the protective mesh cover 2. Two rectangular slots 6 are formed on the lower surface of the controller body 1, and both rectangular slots 6 are movably connected to the protective mesh cover 2. The controller body 1 is equipped with a screen display interface, which can intuitively display information such as the set temperature, working time, and current heating status. For ease of operation and viewing, a set of heat dissipation slots 5 are provided on the bottom of the controller body 1 for heat dissipation. A protective mesh cover 2 is provided on the surface of the heat dissipation slots 5 to prevent foreign objects from entering the controller body 1 through the heat dissipation slots 5. When it is necessary to remove the protective mesh cover 2, press the pressing block 3 to move the limiting block 11 fixed to it. The limiting block 11 moves downward and disengages from the protective mesh cover 2, opening the limit. At this time, the protective mesh cover 2 can be slid off for removal. The protective mesh cover 2 is connected by two rectangular slots 6 on the controller body 1. The rectangular slots 6 are provided with grooves to limit the protective mesh cover 2. The detachable protective mesh cover 2 makes it convenient for users to remove it regularly for cleaning, maintain the ventilation performance of the mesh cover, and ensure good heat dissipation of the controller body 1.

[0026] Two arc-shaped grooves 9 are formed on the surface of the pressing block 3, and both arc-shaped grooves 9 are movably engaged with the fixed base 4. The protective mesh cover 2 has a limit groove 7 formed on its surface, and the limit groove 7 is movably engaged with the limit block 11. The cleaning block 8 is movably engaged with a set of heat dissipation slots 5. During the disassembly of the protective mesh cover 2, the cleaning block 8 fixed on it also moves. The cleaning block 8 is engaged in a set of heat dissipation slots 5. As it moves, it will clean the dust accumulated on the inner wall of the heat dissipation slots 5 and push the dust out. When the user disassembles the protective mesh cover 2, the opening of the heat dissipation slots 5 should face down to prevent dust from falling into the controller body 1. At the same time as the protective mesh cover 2 is removed, the cleaning block 8 can immediately play its role, quickly removing dust and debris in the heat dissipation slots 5, greatly improving cleaning efficiency and saving the user's time and effort.

[0027] Among them, the controller body 1 is the main body of the digital temperature control electric blanket controller, equipped with a screen display operation interface to display information such as the set temperature, and heat dissipation groove 5 is opened on the lower surface to dissipate heat and provide an installation base for other components to realize the control of the electric blanket.

[0028] Protective mesh cover 2: Installed on the lower surface of the controller body 1, it is used to protect the heat dissipation groove 5, prevent foreign objects from entering the controller body 1 through the heat dissipation groove 5, and is removable for regular cleaning to maintain ventilation performance;

[0029] Pressing block 3: Located above the fixed base 4, pressing it can move the limiting block 11, thereby releasing the limit on the protective net cover 2 and facilitating the disassembly of the protective net cover 2. The arc groove 9 on the surface is movably engaged with the fixed base 4.

[0030] Fixed base 4: Fixed on the lower surface of the controller body 1, providing an installation position for the pressing block 3. It plays a guiding and supporting role in the movement of the pressing block 3 by movably engaging with the arc groove 9 on the surface of the pressing block 3.

[0031] Heat dissipation slot 5: It is located on the lower surface of the controller body 1 and is used to dissipate the heat generated when the controller is working to ensure the normal operation of the controller. Its surface is protected by a protective mesh cover 2.

[0032] Rectangular groove 6: It is opened on the lower surface of the controller body 1 and is movably connected to the protective net cover 2. The groove inside the groove limits the protective net cover 2, ensuring that the protective net cover 2 is installed firmly and is easy to disassemble.

[0033] Limiting groove 7: It is formed on the surface of the protective net cover 2 and is movablely engaged with the limiting block 11. It works with the limiting block 11 to limit the protective net cover 2 and prevent the protective net cover 2 from moving at will.

[0034] Cleaning block 8: Fixed to the upper surface of the protective mesh cover 2, during the disassembly of the protective mesh cover 2, as the protective mesh cover 2 moves, it cleans the dust accumulated on the inner wall of the heat dissipation groove 5, improving cleaning efficiency;

[0035] Arc-shaped groove 9: It is formed on the surface of the pressing block 3 and is movably engaged with the fixed seat 4. When the pressing block 3 moves, it plays a guiding role, ensuring that the pressing block 3 moves along a predetermined trajectory, thereby accurately controlling the limit block 11.

[0036] Reset spring 10: Connected to the upper surface of the pressing block 3, when the pressing block 3 is pressed, it provides elastic force to reset it so that the protective net cover 2 can be limited again, ensuring the stable installation of the protective net cover 2;

[0037] Limiting block 11: Fixed on the annular side of the pressing block 3, and movably engaged with the limiting groove 7 on the protective net cover 2. When the pressing block 3 is pressed, the limiting block 11 moves to realize the limiting and releasing functions of the protective net cover 2.

[0038] Working principle:

[0039] The controller body 1 is equipped with a screen display interface, which can intuitively display information such as set temperature, working timer, and current heating status, making it convenient for users to operate and view. A set of heat dissipation slots 5 are provided at the bottom of the controller body 1 for heat dissipation. A protective mesh cover 2 is provided on the surface of the heat dissipation slots 5 to prevent foreign objects from entering the controller body 1 through the heat dissipation slots 5. When it is necessary to remove the protective mesh cover 2, pressing the pressing block 3 moves the limiting block 11 fixed to it. The limiting block 11 moves downward, disengaging from the protective mesh cover 2, thus opening the limit. At this time, the protective mesh cover 2 can be slid out for removal. The protective mesh cover 2 is connected by two rectangular slots 6 on the controller body 1. The rectangular slots 6 are provided with recesses... The groove limits the movement of the protective mesh cover 2. The detachable protective mesh cover 2 allows users to remove it regularly for cleaning, maintaining the ventilation performance of the mesh cover and ensuring good heat dissipation of the controller body 1. During the removal of the protective mesh cover 2, the cleaning block 8 fixed on it also moves. The cleaning block 8 is engaged in a set of heat dissipation grooves 5. As it moves, it will clean the dust accumulated on the inner wall of the heat dissipation grooves 5 and push the dust out. When removing the protective mesh cover 2, the user needs to keep the opening of the heat dissipation grooves 5 facing down to prevent dust from falling into the controller body 1. At the same time as removing the protective mesh cover 2, the cleaning block 8 can immediately play its role, quickly removing dust and debris from the heat dissipation grooves 5, greatly improving cleaning efficiency and saving the user's time and effort.

[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
