Description
Technical Field
[0001] This utility model relates to the field of driver boards, specifically a driver board for small household appliances with good heat dissipation. Background Technology
[0002] The main function of a small appliance driver board is to control and drive various hardware devices within the appliance. The driver board receives instructions from the main control device (such as the motherboard or external devices), converts them into control signals, and thus controls and drives the operation of other hardware devices. Small appliances, as an indispensable part of modern life, contain a wide variety of internal circuit boards, each with its own function, working together to ensure the normal operation of the appliance. The circuit board, as the "brain" of the small appliance, not only controls the implementation of various functions but also undertakes important tasks such as current distribution and signal processing.
[0003] Existing driver boards are mainly used to drive motors, heating elements, and electronic components in small household appliances to achieve power output or heating functions. However, existing small household appliance driver boards still have the following problems during use:
[0004] The electronic components on existing driver boards easily generate heat during operation. Cooling fans can be installed on the driver board to cool these components. However, because the cooling fan is fixed in its position, the distance between the fan and all the electronic components varies, resulting in poor cooling for some components and affecting the overall heat dissipation of the driver board. Therefore, it is necessary to develop a small appliance driver board with good heat dissipation for use in the existing driver board field. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, the fixed mounting position of the existing cooling fan on the driver board results in varying distances between all electronic components and the cooling fan, leading to poor cooling of some electronic components and affecting the heat dissipation effect on the electronic components of the driver board. This utility model proposes a small appliance driver board with better heat dissipation effect.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a small household appliance drive board with good heat dissipation, comprising:

The heat-insulating horizontal tubes are located above the main body of the small appliance drive board, and the interior of the heat-insulating horizontal tubes is connected to the assembly tube.
[0010] Preferably, each of the heat-insulating horizontal tubes is fixedly equipped with an air outlet pipe at its bottom, and the interior of the air outlet pipe is connected to the heat-insulating horizontal tube.
[0011] Preferably, multiple metal heat dissipation plates are fixedly installed in the hollow part of the cover, and the connecting pipe is located above the hollow part of the cover.

[0016] The advantages of this utility model are:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0030] This application discloses a small household appliance driver board with good heat dissipation. (Refer to...) Figure 1 and Figure 4 as well as Figure 5 A small appliance drive board with good heat dissipation includes a small appliance drive board body 10. Multiple connecting posts 12 are fixedly mounted on the small appliance drive board body 10. A heat dissipation mechanism 22 is mounted on each connecting post 12. The heat dissipation mechanism 22 includes a cooling fan 2201. A support post 2206 is fixedly mounted on the cooling fan 2201. A cover 2207 is fixedly mounted on the top of each support post 2206. The bottom of the cover 2207 is hollow. Multiple connecting pipes 2208 are fixedly mounted on the sides of the cover 2207, communicating with the hollow portion of the cover 2207. One end of each connecting pipe 2208 is fixedly mounted with a conveying pipe 2209 communicating with it. The conveying pipe 2209 is located outside the cover 2207. Multiple connecting pipes 2209 are fixedly mounted on the bottom of the conveying pipe 2209. A vertical pipe 2210 is located on one side of the cover 2207. Multiple vertical pipes 2210 have an assembly pipe 2211 fixedly mounted at their bottom. The assembly pipe 2211 is close to the surface of the small appliance drive board body 10, and its interior is connected to the vertical pipe 2210. Multiple heat-insulating horizontal pipes 2212 are fixedly mounted on the assembly pipe 2211, located above the small appliance drive board body 10. The interior of the heat-insulating horizontal pipe 2212 is connected to the assembly pipe 2211. A vent pipe 2213 is fixedly mounted at the bottom of each heat-insulating horizontal pipe 2212, and its interior is connected to the heat-insulating horizontal pipe 2212. Multiple metal heat dissipation plates 2214 are fixedly mounted in the hollowed-out portion of the cover 2207. The connecting pipe 2208 connects to the hollowed-out portion of the cover 2207 above the metal heat dissipation plates 2214.
[0031] In this invention, when the cooling fan 2201 is activated, the airflow generated by the cooling fan 2201 comes into contact with the metal heat dissipation plate 2214, and the airflow temperature decreases. The cooled airflow enters the conveying pipe 2209 through the connecting pipe 2208, then enters the vertical pipe 2210 through the conveying pipe 2209, and then enters the assembly pipe 2211 through the vertical pipe 2210. The heat-insulating horizontal pipe 2212 can insulate the flow of airflow, so that the air outlet pipe 2213 can blow the cooled airflow onto the electronic components on the small appliance drive board body 10, which facilitates the corresponding heat dissipation of the electronic components on the small appliance drive board body 10 and improves the heat dissipation effect.
[0032] Reference Figures 1-4Each connecting post 12 has a mounting hole 20 on its top. Each vertical tube 2210 has multiple connecting blocks 2202 fixedly mounted on its side. Each connecting block 2202 has a mounting hole 2203. When the connecting block 2202 is assembled with the connecting post 12, the mounting hole 2203 communicates with the mounting hole 20. The mounting hole 2203 on the connecting block 2202 and the mounting hole 20 on the connecting post 12 are threaded with fastening bolts 21. A conductive connector 13 is fixedly mounted on the main body 10 of the small appliance drive board. A connecting wire 2204 is fixedly mounted on the cooling fan 2201. One end of the connecting wire 2204 is fixedly mounted with a connecting plug 2205. The connecting plug 2205 is plugged into the conductive connector 13. The main body 10 of the small appliance drive board has multiple connecting holes 11.
[0033] In this utility model, when the connecting block 2202 is assembled with the connecting post 12, the assembly hole 2203 communicates with the mounting hole 20. At this time, fastening bolts 21 are installed on the assembly hole 2203 on the connecting block 2202 and the mounting hole 20 on the connecting post 12, thereby improving the stability between the cooling fan 2201 and the main body 10 of the small appliance drive board. The connector 2205 on the connecting wire 2204 is inserted into the conductive connector 13. When the small appliance is running, the conductive connector 13 conducts electricity to the connecting wire 2204 on the connector 2205, and the cooling fan 2201 starts to generate airflow.
[0034] Working principle: When the connecting block 2202 is assembled with the connecting post 12, the assembly hole 2203 communicates with the mounting hole 20. At this time, fastening bolts 21 are installed on the assembly hole 2203 on the connecting block 2202 and the mounting hole 20 on the connecting post 12, which improves the stability between the cooling fan 2201 and the small appliance drive board body 10. The connector 2205 on the connecting wire 2204 is inserted into the conductive connector 13. When the small appliance is running, the conductive connector 13 conducts electricity to the connecting wire 2204 on the connector 2205, and the cooling fan 2201 starts. The airflow generated by the cooling fan 2201 comes into contact with the metal heat sink 2214, and the airflow temperature decreases. The cooled airflow enters the delivery pipe 2209 through the connecting pipe 2208, then enters the vertical pipe 2210 through the delivery pipe 2209, and then enters the assembly pipe 2211 through the vertical pipe 2210. The heat-insulating horizontal pipe 2212 can insulate the flow of airflow, so that the air outlet pipe 2213 can blow the cooled airflow onto the electronic components on the small appliance drive board body 10, which facilitates heat dissipation of the electronic components on the small appliance drive board body 10 and improves the heat dissipation effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
