The top cover is provided on the top of the bottom shell. The top cover is provided with buckles on its left and right sides and the buckles are engaged with the blocks. The bottom surface inside the bottom shell is fixedly installed with insert sleeves at its four corners. The top of the insert sleeves is fixedly installed with rubber buffer rings and fixed blocks on the top of the rubber buffer rings. The circuit board body is fixedly connected to the four fixed blocks.

Detailed Implementation

[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] Example

[0019] Please see Figure 1 A mixer circuit board that is easy to assemble includes an upper cover 1 and a bottom shell 2. The bottom shell 2 is provided with quick-release mechanisms 6 at the four corners for quick installation and disassembly. The bottom shell 2 is fixedly installed with clips 4 on the left and right sides respectively. The top cover 1 is provided on the top of the bottom shell 2. The upper cover 1 is installed with buckles 5 on the left and right sides respectively. The buckles 5 are engaged with the clips 4, realizing quick assembly between the upper cover 1 and the bottom shell 2.

[0020] In use, the top cover 1 and the bottom shell 2 are assembled together by the buckle 5 and the locking block 4 to form a protective shell, which effectively protects the circuit board body 8 and extends its service life. The snapping of the buckle 5 and the locking block 4 is simple and quick compared to the traditional screw installation method, and does not require the use of screwdrivers or other tools.

[0021] Please see Figure 1 , Figure 2 and Figure 4 Inside the bottom shell 2, at the four corners of the bottom surface, there are four plug-in sleeves 7. A rubber buffer ring 11 is fixedly installed on the top of the plug-in sleeve 7. A fixing block 10 is supported on the top of the rubber buffer ring 11. The circuit board body 8 is fixedly connected to the four fixing blocks 10. A plug-in hole 9 is opened in the center of the fixing block 10. At the four corners of the bottom of the top cover 1, there are four plug-in rods 16. A crimping ring 15 is fixedly sleeved on the lower part of the plug-in rod 16. The bottom of the plug-in rod 16 moves through the plug-in hole 9 and is inserted into the inside of the plug-in sleeve 7. The crimping ring 15 is crimped on the top of the fixing block 10.

[0022] In use, first fix the fixing block 10 to the four corners of the circuit board body 8, and make insertion holes 9 on the fixing block 10. Place the fixing block 10 on the top of the rubber buffer ring 11, and ensure that the insertion hole 9 is aligned with the center hole inside the insertion sleeve 7. Then, insert the insertion rod 16 of the upper cover 1 through the insertion hole 9 and insert it into the insertion sleeve 7. Then, use the snap-fit ​​between the buckle 5 and the snap-fit ​​block 4 to fix it, thus realizing the snap-fit ​​installation between the upper cover 1 and the bottom shell 2, and at the same time realizing the installation of the circuit board body 8. The assembly is convenient and the operation is simple. The rubber buffer ring 11 is used to buffer the circuit board body 8 and extend its service life.

[0023] Please see Figure 2 and Figure 3 Several air inlets 3 are evenly distributed in the middle of the front side of the bottom shell 2. A filter screen 13 is fixedly installed on the inner wall of the middle of the front side of the bottom shell 2. After being filtered by the filter screen 13, the outside air enters the interior of the bottom shell 2 through the air inlets 3. An exhaust port 14 is provided in the middle of the rear side of the bottom shell 2, and a suction fan 12 is fixedly installed on the inner wall of the rear side of the bottom shell 2. The suction fan 12 draws the hot air inside the bottom shell 2 out through the exhaust port 14, thereby achieving rapid heat dissipation of the circuit board body 8.

[0024] Please see Figure 2 and Figure 3 The quick disassembly mechanism 6 includes mounting plates 64 fixedly installed at the four corners of the bottom shell 2. A nut block 63 is fixedly installed at the top center of the mounting plate 64. A screw 62 is movably passed through the center of the nut block 63. The screw 62 and the nut block 63 are connected by threads. A handle 61 is fixedly installed at the top of the screw 62.

[0025] After the circuit board body 8, the top cover 1 and the bottom shell 2 are assembled, align the screw 62 with the corresponding mounting hole on the electrical control box of the mixer. Then turn the handle 61 to rotate the screw 62 synchronously, and install the screw 62 into the mounting hole. This achieves the overall installation of the equipment without the need for special tools, making installation and disassembly convenient.

[0026] It should be noted that this easy-to-assemble mixer circuit board, when in use, first place the fixing block 10 on top of the rubber buffer ring 11, and ensure that the insertion hole 9 is aligned with the center hole inside the insertion sleeve 7. At this time, insert the insertion rod 16 of the upper cover 1 through the insertion hole 9 and insert it into the insertion sleeve 7. Then, use the snap-fit ​​between the buckle 5 and the snap-fit ​​block 4 to fix it, thus realizing the snap-fit ​​installation between the upper cover 1 and the bottom shell 2. Then, use the quick disassembly mechanism 6 to install the upper cover 1 and the bottom shell 2 onto the mixer. The installation and disassembly are simple. The upper cover 1 and the bottom shell 2 together form a protective shell to protect the circuit board body 8, avoiding the impact of dust and impact on the service life of the circuit board. In addition, the suction fan 12 realizes the suction inside the upper cover 1 and the bottom shell 2, realizing rapid heat dissipation.

[0027] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
