Description

Technical Field

[0001] This utility model relates to the field of electric blanket control, and in particular to a single-sided circuit board for an electric blanket controller. Background Technology

[0002] Traditional circuit boards have high processing costs and high defect rates during production. This is because during processing, the SMT components on the back are first attached with high-temperature tape, and then the through-hole components on the front are inserted and wave soldered. After wave soldering, many SMT components on the back fall off, so the circuit boards need to be repaired manually. Therefore, the processing cost is very high, and the stability of the assembled product is also poor. Utility Model Content

[0017] The beneficial effects of this utility model are as follows:

[0018] The improved circuit board of this invention has all components on the front, so there will be no component falling off during processing, and the processing cost is much lower than that of the original circuit board.

[0019] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention.

[0022] In the attached diagram:

[0023] Figure 1 This is a component distribution diagram of a single-sided circuit board for an electric blanket controller according to an embodiment of this utility model. Detailed Implementation

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] like Figure 1 As shown, this embodiment provides a single-sided circuit board for an electric blanket controller, including:

[0026] Circuit board body 1;

[0027] The main body of the circuit board includes a component side and a soldering side; wherein, the component side includes a first mounting area 41, a second mounting area 42 and a third mounting area 43;

[0028] The soldering surfaces are configured with soldering points corresponding to the first patch area 41, the second patch area 42 and the third patch area 43.

[0029] The technical principle of the above counting scheme is as follows:

[0030] In actual implementation, FR-4 copper-clad laminates with a size of no less than 150mm × 100mm are selected. Solder resist ink is printed on one side of the copper-clad laminate to form the soldering surface of the circuit board body 1; the other side serves as the component surface. Regarding the component layout, the component surface of the circuit board body 1 is divided into three surface mount areas as follows: First surface mount area 41: no less than 50mm × 40mm, used for mounting the surface mount component distribution matrix of the electric blanket controller, etc. Second surface mount area 42: no less than 30mm × 20mm, used to complement components such as digital tubes. Third surface mount area 43: 10mm × 10mm, used to mount large-capacity single surface mount capacitors.

[0031] The surface mount solder joints are configured on the soldering surface of the circuit board body 1, corresponding to the positions of the first surface mount area 41, the second surface mount area 42, and the third surface mount area 43. Lead-free solder is used for the solder joints, providing excellent soldering performance.

[0032] The improved circuit board of this invention has all components on the front, so there is no risk of components falling off during processing, and the processing cost is much lower than that of the original circuit board. Furthermore, regarding the layout, traditional electric blanket controller circuit boards are PCB-packaged according to the specific circuit, which inevitably results in electronic components on both sides. This is based on the inherent circuit board design. This invention, however, defines and fixes electronic components in different areas, thus placing all electronic components on the front of the circuit board and preventing them from falling off.

[0033] As one embodiment of this utility model:

[0034] The component has a first mounting hole 11 at its upper left corner, a second mounting hole 12 at its upper right corner, a third mounting hole 13 at its lower right corner, and a fourth mounting hole 14 at its lower left corner.

[0035] In practice, the circuit board can be fixed inside the controller of the electric blanket through the mounting holes.

[0036] As one embodiment of this utility model:

[0037] An adjacent first AC port 21 and a second AC port 22 are provided between the first mounting hole 11 and the second mounting hole 12; an adjacent first output port 23 and a second output port 24 are provided between the third mounting hole 13 and the fourth mounting hole 14.

[0038] In actual implementation, the first AC port 21 and the second AC port 22 are used to connect to AC power, and the first output port 23 and the second output port 24 are used to output control result information.

[0039] As one embodiment of this utility model:

[0040] A digital tube 3 is provided in the middle of the component surface.

[0041] In practice, the digital tube 3 can display the real-time temperature of the electric blanket.

[0042] As one embodiment of this utility model:

[0043] The digital tube 3 has a second fuse 52 on its right side and a first fuse 51 on its left side. The second fuse 52 is a temperature fuse.

[0044] In practice, the first fuse is an overvoltage or short-circuit fuse. The second fuse is used for temperature sensing to prevent the electric blanket from overheating.

[0045] As one embodiment of this utility model:

[0046] A first embedded chip socket 6 is fixed below the digital tube 3, and a second embedded chip socket 8 is disposed on the lower right side of the first embedded chip socket 6.

[0047] In practical implementation, the first embedded chip socket 6 and the second embedded chip socket 8 can embed different control chips, expanding the specific functions of the circuit board of this utility model. A fast recovery diode 61 is arranged on the lower left side of the second embedded chip socket 8, which is used to reduce the reverse recovery time when receiving instructions from the chip, thereby reducing noise and electromagnetic interference in the circuit.

[0048] As one embodiment of this utility model:

[0049] The first electrolytic capacitor 71, the second electrolytic capacitor 72, the third electrolytic capacitor 73 and the fourth electrolytic capacitor 74 are fixed sequentially on the left side of the component surface; the fifth electrolytic capacitor 75 and the sixth electrolytic capacitor 76 are fixed sequentially on the right side of the component surface.

[0050] In practical applications, electrolytic capacitors are primarily used for filtering and voltage regulation in circuits. The sequential arrangement of the first electrolytic capacitor 71, the second electrolytic capacitor 72, the third electrolytic capacitor 73, the fourth electrolytic capacitor 74, the fifth electrolytic capacitor 75, and the sixth electrolytic capacitor 76 effectively filters out AC ripple in the circuit, ensuring the stability of the DC power supply. This reduces interference with the heating element of the electric blanket, improving the stability and reliability of the electric blanket's operation. The electrolytic capacitors are distributed on both sides of the circuit board, contributing to a more uniform heat distribution, preventing localized overheating, and improving the overall heat dissipation performance of the circuit board.

[0051] As one embodiment of this utility model:

[0052] The fifth electrolytic capacitor 75 has a first inductor 91 fixed inside, and the second electrolytic capacitor 72 has a second inductor 92 disposed inside.

[0053] In practical implementation, inductors 91 and 92, together with electrolytic capacitors 75 and 72, can form an LC filter. LC filters offer better filtering performance than filters using capacitors or inductors alone, more effectively removing high-frequency noise and ripple from the circuit, thus providing a cleaner DC power supply. Increasing the inductance reduces electromagnetic interference (EMI) and improves the circuit's immunity to EMI, enhancing the overall system's electromagnetic compatibility. A surface-mount rectifier diode 81 is fixedly connected to the upper side of the first inductor for rectification when an external power supply is present; the rectified current is then stored in the electrolytic capacitor.

[0054] As one embodiment of this utility model:

[0055] A controllable switch 10 is also fixedly embedded in the middle of the component surface, and a thyristor 711 is arranged on the lower side of the controllable switch 10.

[0056] In practical implementation, the controllable switch 10 can achieve precise circuit control, opening or closing the circuit manually or automatically to control the flow of current. The controllable switch 10 can quickly disconnect the circuit in case of overload or short circuit, protecting other components from damage. The controllable switch 10 can cooperate with other control units in the circuit (such as microcontrollers) to achieve intelligent circuit management, such as timed switching and remote control.

[0057] As one embodiment of this utility model:

[0058] A pin header interface 111 is also fixed to the middle left side of the component surface.

[0059] In practical implementation, the pin header interface 111 can be used to connect to test equipment, facilitating circuit debugging and testing during product development and production. For circuits that require frequent functional testing or parameter adjustments, the pin header interface provides a stable and reliable connection point. If the circuit needs upgrading or maintenance, the pin header interface 111 makes it easier to replace or upgrade parts of the circuit board. Modules connected via the pin header interface can be quickly replaced, thereby reducing repair time and lowering maintenance costs.

[0060] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
