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 protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-5 The present invention provides the following technical solution: a dilution cabinet for high concentration liquid detection, comprising a dilution cabinet body 1, a dilution cylinder 2 fixedly connected in the middle inside the dilution cabinet body 1, a sealing cylinder cover 3 installed above the dilution cylinder 2, a stirrer 4 installed in the middle of the sealing cylinder cover 3, an electrical device 6 fixedly connected in the upper part inside the dilution cabinet body 1, a cleaning component 5 installed inside the dilution cylinder 2, and a ventilation and heat dissipation component 7 installed in the upper part of the dilution cabinet body 1.

[0024] Specifically, the cleaning component 5 includes a connecting rod 51, an abutting rod 52, an abutting spring 53, a cleaning brush 54, a limiting slider 55, a limiting slide bar 56, and an auxiliary component 57. The connecting rod 51 is fixedly connected to one side of the rotating rod of the stirrer 4. The abutting rod 52 is slidably connected to one end of the connecting rod 51. The abutting spring 53 is fixedly connected to one end of the abutting rod 52. The cleaning brush 54 is fixedly connected to the other end of the abutting rod 52. The limiting slider 55 is fixedly connected above the abutting rod 52. The limiting slide bar 56 slides in the middle of the limiting slider 55. The auxiliary component 57 is fixedly connected to both ends above the sealing cylinder cover 3.

[0025] By adopting the above technical solution, the agitator 4 can drive the cleaning brush 54 to rotate, clean the inside of the dilution cylinder 2, and wash it with water. In use, the abutment spring 53 and the abutment rod 52 cooperate to make the cleaning brush 54 abut against the inside of the dilution cylinder 2, so that the cleaning effect is good.

[0026] Specifically, the auxiliary component 57 includes a slide block 571, a lifting slide rod 572, a fixed rod 573, a fixed slider 574, and a fixed spring 575. The two ends of the sealing cylinder cover 3 are fixedly connected to the slide block 571. The lifting slide rod 572 is slidably connected to one end of the slide block 571. The fixed rod 573 is tightly inserted into one end of the lifting slide rod 572 inside the slide block 571. The fixed slider 574 is fixedly connected above the fixed rod 573. The fixed spring 575 is fixedly connected to one side of the fixed slider 574.

[0027] By adopting the above technical solution, when it is necessary to open the sealing cylinder cover 3 to maintain or replace the agitator 4 or cleaning components, hold the handle 576 with both hands and pull the fixing rod 573. The fixing rod 573 drives the fixing slider 574 to move and compress the fixing spring 575, so that the fixing rod 573 disengages from the fixing hole on one side of the lifting slide rod 572. Then push the slide 571 to move on the lifting slide rod 572, thereby driving the sealing cylinder cover 3 to move upward and open. When the slide 571 moves to the point where the fixing rod 573 and the fixing hole on the other side are aligned, release the fixing rod 573 so that the fixing rod 573 is inserted into the other fixing hole for fixing, thereby removing the cleaning component 5 and the agitator 4 for maintenance or replacement.

[0028] Specifically, a handle 576 is fixedly connected to one end of the fixed rod 573, and a fixing hole is opened on one side of the lifting slide rod 572 to be tightly inserted into the fixed rod 573.

[0029] By adopting the above technical solution, the handle 576 is designed to facilitate the pulling of the fixing rod 573, and the fixing hole facilitates the insertion of the fixing rod 573 to fix the lifting slide rod 572 and the slide block 571.

[0030] In this embodiment, during use: the cleaning brush 54 drives the agitator 4 to rotate, cleaning the inside of the dilution cylinder 2. Water is used for rinsing. During use, the abutment spring 53 and the abutment rod 52 work together to ensure the cleaning brush 54 contacts the inside of the dilution cylinder 2, resulting in good cleaning. When it is necessary to open the sealing cylinder cover 3 to maintain or replace the agitator 4 or cleaning components, hold the handle 576 with both hands and pull the fixing rod 573. The fixing rod 573 moves the fixing slider 574, compressing the fixing spring 575, causing the fixing rod 573 to disengage from the lifting slide rod. The fixing hole on one side of 572 is then pushed to move the slide block 571 on the lifting slide rod 572, thereby causing the sealing cylinder cover 3 to move upward and open. When the slide block 571 moves to the point where the fixing rod 573 and the fixing hole on the other side are aligned, the fixing rod 573 is released, allowing the fixing rod 573 to be inserted into another fixing hole for fixation. This allows the cleaning component 5 and the agitator 4 to be removed for maintenance and replacement. This device facilitates the cleaning of the inside of the dilution cylinder 2 during use. Furthermore, during use, the abutment spring 53 allows the cleaning brush 54 to abut against the inside of the dilution cylinder 2, resulting in a good cleaning effect.

The heat sink 71 is fixedly connected to the top of the dilution cabinet body 1, the heat dissipation fan 72 is fixedly connected to the lower part inside the heat sink 71, the positioning rod 74 is tightly inserted into both ends of the top of the heat sink 71, the cover plate 73 is fixedly connected to the top of the positioning rod 74, the external threaded seat 75 is fixedly connected to the middle of the bottom of the cover plate 73, the internal threaded seat 76 is threadedly connected to the surface of the external threaded seat 75, and the filter cartridge 77 is fixedly connected to the bottom of the internal threaded seat 76.

[0033] By adopting the above technical solution, the cooling fan 72 is started, and the air enters the heat sink 71 through the holes of the cover plate 73, is filtered by the filter cartridge 77, and then enters the dilution cabinet body 1 to blow air to cool the electrical equipment 6. Then the air is discharged through the air outlets on both sides of the dilution cabinet body 1.

[0034] Specifically, a limiting block 78 is tightly inserted into one side of the positioning rod 74, and a limiting screw 79 is rotatably connected to one end of the limiting block 78. The limiting screw 79 is threadedly connected to the heat sink 71.

[0035] By adopting the above technical solution, when the filter cartridge 77 needs to be disassembled and cleaned, the limiting screw 79 is rotated, and the limiting screw 79 drives the limiting block 78 to move, so that it is disengaged from the positioning rod 74. Then, the cover plate 73 can be removed to separate the cover plate 73 from the heat sink 71. Then, the filter cartridge 77 can be rotated by the cooperation of the external thread seat 75 and the internal thread seat 76 to remove the filter cartridge 77 for cleaning.

[0036] In this embodiment, when in use: the cooling fan 72 is turned on, and the air enters the heat sink 71 through the holes in the cover plate 73, is filtered by the filter cartridge 77, and then enters the dilution cabinet body 1 to cool the electrical equipment 6. The air is then discharged through the air outlets on both sides of the dilution cabinet body 1. When the filter cartridge 77 needs to be disassembled and cleaned, the limiting screw 79 is rotated, which drives the limiting block 78 to move, causing it to disengage from the positioning rod 74. Then, the cover plate 73 can be removed to separate it from the heat sink 71. Then, the filter cartridge 77 is rotated through the engagement of the external thread seat 75 and the internal thread seat 76 to remove it for cleaning. This device facilitates ventilation and heat dissipation for the components inside the dilution cabinet body 1 during operation.

[0037] In this utility model, the cooling fan 72 is a previously disclosed technology, and the selected model is GX12038.

[0038] The structure and working principle of the dilution cabinet body 1, dilution cylinder 2 and stirrer 4 in this utility model have been disclosed in a dilution cabinet for high concentration liquid detection disclosed in Chinese patent application number 202322634274.3. Its working principle is that high concentration liquid and water are respectively introduced into the dilution cylinder 2 through the liquid inlet pipe, and the dilution is carried out by stirring with the stirrer 4.

[0039] The working principle and usage process of this utility model are as follows: This utility model is used for the detection of high-concentration liquids to dilute them. During use, the pipeline is connected, and the high-concentration liquid and water are respectively introduced into the dilution cylinder 2 through the inlet pipe. The controller of the dilution cabinet body 1 controls the stirrer 4 to stir and dilute the liquid. During use, the ventilation and heat dissipation component 7 facilitates ventilation and heat dissipation for the electrical equipment 6 in the dilution cabinet body 1. After use, water is injected into the dilution cylinder 2, and then the cleaning component 5 is used for cleaning. When using the cleaning component 5, the cleaning brush 54 allows the stirrer 4 to be cleaned. The cleaning brush 54 rotates to clean the inside of the dilution cylinder 2, and is used in conjunction with water for scrubbing. During use, the abutment spring 53 and abutment rod 52 work together to ensure the cleaning brush 54 contacts the inside of the dilution cylinder 2, resulting in a good cleaning effect. When it is necessary to open the sealing cylinder cover 3 to maintain or replace the agitator 4 or other cleaning components, hold the handle 576 with both hands and pull the fixing rod 573. The fixing rod 573 moves the fixing slider 574, compressing the fixing spring 575, causing the fixing rod 573 to disengage from the fixing hole on one side of the lifting slide rod 572. Then, it pushes the slide block 571 to move on the lifting slide rod 572, thereby... The dynamic sealing cylinder cover 3 moves upward and opens. When the slide 571 moves to the point where the fixing rod 573 aligns with the fixing hole on the other side, the fixing rod 573 is released, allowing it to be inserted into the other fixing hole for fixation. This allows the cleaning component 5 and the agitator 4 to be removed for maintenance and replacement. This device facilitates the cleaning of the inside of the dilution cylinder 2 during use. Furthermore, the structure, through the abutment spring 53, ensures that the cleaning brush 54 can contact the inside of the dilution cylinder 2, resulting in good cleaning performance. When using the ventilation and heat dissipation component 7, the cooling fan 72 is activated, and air enters the heat dissipation base 71 through the holes in the cover plate 73, passing through a filter... The filter cartridge 77 filters the air and then enters the dilution cabinet body 1 to blow air and dissipate heat from the electrical equipment 6. The air is then discharged through the air outlets on both sides of the dilution cabinet body 1. When it is necessary to disassemble and clean the filter cartridge 77, rotate the limit screw 79. The limit screw 79 drives the limit block 78 to move, causing it to disengage from the positioning rod 74. Then, the cover plate 73 can be removed to separate it from the heat sink 71. Then, the filter cartridge 77 can be rotated through the engagement of the external thread seat 75 and the internal thread seat 76 to remove it for cleaning. This device facilitates ventilation and heat dissipation for the components inside the dilution cabinet body 1 during operation.
