[0028] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0029] Reference Figures 1 to 9 , an embodiment of the circuit board cooling protection system of the wall breaking machine of the utility model is proposed:
[0030] A circuit board cooling protection system for a wall-breaking machine is used to dissipate heat and cool the circuit board in the housing of the wall-breaking machine. The system includes a radiator 2 arranged on the circuit board 1 and a ventilation channel arranged in the housing and connected to the radiator 2. The outer end of the ventilation channel is conducted to the outside of the housing through a ventilation hole 5 arranged on the housing, which is used to discharge the heat of the radiator 2. When in use, the heat of the circuit board 1 is transferred to the radiator 2, and the radiator 2 dissipates the heat to the air around it. The hot air is exchanged with the cold air outside the housing through the ventilation channel, so as to improve the heat dissipation performance, realize the cooling protection of the circuit board 1, avoid the overheating of the circuit board 1 affecting its working performance, and extend the service life of the circuit board 1.
[0031] The heat sink 2 is arranged on the back of the circuit board 1, and the heat sink 2 separates the inner cavity of the ventilation channel from the circuit board 1, so that even if liquid enters from the ventilation channel, it will be blocked by the heat sink 2 and will not affect the circuit board 1. In addition, applying waterproof glue on the surface of the circuit board 1 can further prevent water and cockroaches and avoid short circuit when encountering water.
[0032] Since wall breaking machines are often used to make soy milk, juice, etc., there is often liquid involved, and there is a possibility that liquid will spill, so there is a possibility that liquid will enter the housing through the ventilation channel. In order to better prevent liquid from entering the housing through the ventilation channel, such as Figure 1-3 As shown in the figure, the ventilation channel 10 in this embodiment is vertically arranged, the ventilation hole 5 is located at the lower end of the ventilation channel 10, and the heat sink 2 is embedded from the side of the ventilation channel 10 to communicate with the ventilation channel 10. The heat sink 2 includes a heat dissipation back plate 21 located on the back of the circuit board 1 and a plurality of heat sinks 22 vertically arranged on the heat dissipation back plate 21. The heat sinks 22 are relatively spaced to form heat dissipation grooves 23 to accelerate heat dissipation. The heat sink 22 extends into the inner cavity of the ventilation channel 10, and the heat dissipation grooves 23 are communicated with the ventilation channel 10. The heat dissipation back plate 21 blocks the embedded position between the heat sink 2 and the ventilation channel 10 to separate the inner cavity of the ventilation channel from the circuit board 1.
[0033] In another preferred embodiment, Figure 4-9 As shown, the ventilation channel is L-shaped, including a low-level channel 3 arranged horizontally and a high-level channel 4 arranged vertically. One end of the low-level channel 3 leads to the outside of the shell, and the other end is sealed and connected with the low-level end of the high-level channel 4. The high-level end of the high-level channel 4 is connected with the inner cavity of the shell, and the high-level channel 4 and the low-level channel 3 are arranged at a right dihedral angle. The liquid entering the ventilation channel can only be discharged into the inner cavity of the shell from the upper port of the high-level channel 4, and the position of the ventilation hole 5 is lower than the upper port of the high-level channel 4. As long as the water level is lower than the upper port of the high-level channel 4, it will not be discharged into the inner cavity of the shell. This design can block the liquid entering the ventilation channel from the ventilation hole 5 in the ventilation channel to avoid contact with the circuit board 1.
[0034] The circuit board 1 is located above the low-level channel 3, and the heat sink 2 is embedded from the side of the high-level channel 4 to communicate with the ventilation channel. The circuit board 1 is located outside the ventilation channel, and the circuit board 1 is separated from the ventilation channel by the heat sink 2. This design realizes the connection between the heat sink 2 and the ventilation channel and the separation between the circuit board 1 and the ventilation channel.
[0035] The heat sink 2 includes a heat dissipation back plate 21 located on the back of the circuit board 1 and a plurality of heat dissipation fins 22 vertically arranged on the heat dissipation back plate 21. The heat dissipation fins 22 are relatively spaced to form heat dissipation grooves 23 to accelerate heat dissipation. The heat dissipation fins 22 extend into the inner cavity of the high-position channel 4. The heat dissipation back plate 21 blocks the embedded position between the heat sink 2 and the high-position channel 4 to separate the inner cavity of the ventilation channel from the circuit board 1.
[0036] The high-level channel 4 includes side enclosures 42 arranged on opposite sides, an end enclosure 41 connected between the two side enclosures 42, and an embedding interface opposite to the end enclosure 41. A side surface of the motor housing in the shell is used as the end enclosure, so there is no need to set up the end enclosure separately, saving materials. The embedding interface is adapted to the radiator 2. The radiator 2 is provided with a plug-in groove 24 with a U-shaped cross section on opposite sides. The side enclosures on both sides are provided with a plug-in column 43. The plug-in column 43 is inserted into the plug-in groove 24, so that the radiator 2 is fixed in the embedding interface, and the assembly operation is simple. The plug-in column 43 is plugged into the plug-in groove 24, and the connection is tight, which can reduce the connection gap between the radiator 2 and the side enclosure 42, and the water sealing effect is good.
[0037] The low-level channel 3 includes a bottom cover 31, side sealing edges 32 arranged on both sides of the bottom cover 31, and a cover plate 33 opposite to the bottom cover 31. The cover plate 33 is covered on the side sealing edges 32, and the circuit board 1 is located above the cover plate 33, which is convenient for assembly. The bottom surface of the housing is used as the bottom cover, and there is no need to set a separate bottom cover, which saves materials.
[0038] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
