Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Refer to the attached Figure 1 , Attachment Figure 2 and attached Figure 3The utility model provides an embodiment: a water quality COD analyzer digestion device, including a body 1, a groove 2 is provided on the top of the body 1, a sample container 3 is fixedly connected to the inner side of the groove 2, a plurality of placement slots 4 are provided on the top of the sample container 3, a top cover 6 is slidably connected to the top of the top cover 6, a slide groove 19 is provided on the top of the slide groove 19, a slide rod 7 is slidably connected to the inner side of the slide rod 7, a fixed plate 8 is fixedly connected to the outer wall of the slide rod 7, a plurality of fixed columns 9 are fixedly connected to the bottom of the fixed plate 8, and the outer walls of the plurality of fixed columns 9 are slidably connected to the groove 2, the outer walls of multiple fixed columns 9 are fixedly connected with adhesive blocks 10, and the outer walls of the adhesive blocks 10 are slidably connected with cleaning cotton 11. The top of the slide rod 7 is fixedly connected with a limit block 20, and the limit block 20 is arranged on the top of the top cover 6. The bottom of the placement groove 4 is provided with a heat conducting mechanism 12, and the heat conducting mechanism 12 is used to heat the sample; the top of the limit block 20 is fixedly connected with an anti-slip cover 21, and the outer wall of the anti-slip cover 21 is made of silicone material; connecting grooves 5 are opened around the top of the body 1, and the inner side of the connecting groove 5 is slidably connected to the bottom of the top cover 6.

[0032] Specifically, by setting up multiple placement slots 4, multiple water samples can be placed at one time to conduct batch COD analysis. In order to ensure the sealing and safety of the samples during the digestion process, a top cover 6 is set on the top of the body 1, and multiple cleaning cottons 11 are connected at the bottom through a slide rod 7, a fixing plate 8, a fixing column 9 and an adhesive block 10. When the instrument is not in use, the cleaning cotton 11 can be exposed to the corresponding placement slot 4 after the top cover 6 is covered, effectively ensuring the cleanliness of the placement slot 4, reducing the accumulation of stains and water stains, preventing bacterial growth, and ensuring the hygiene of the detection environment. At the same time, a connecting slot 5 is set so that the slide rod 7 can slide freely up and down, thereby driving the cleaning cotton 11 to more effectively clean the stains inside the placement slot 4, and the cleaning cotton 11 can be replaced by the adhesive block 10, which increases the service life of the device and reduces the maintenance cost and complexity of the instrument.

[0033] Refer to the attached Figure 1 , Attachment Figure 2 and attached Figure 3 The utility model provides an embodiment: the heat conduction mechanism 12 includes a plurality of heat conduction pads 1201, the outer walls of the plurality of heat conduction pads 1201 are fixedly connected to the inner side of the placement groove 4, the bottoms of the plurality of heat conduction pads 1201 are fixedly connected to heat conduction wires 1202, the bottoms of the plurality of heat conduction wires 1202 are fixedly connected to heating tubes 1203, and the bottoms of the heating tubes 1203 are fixedly connected to the inner side of the body 1; the inner side of the heat conduction pad 1201 is slidably connected to a sample bottle 13, and the top of the sample bottle 13 is threadedly connected to a bottle cap 14; a plurality of heat dissipation holes 15 are opened on the left and right sides of the body 1, and the adjacent sides of the plurality of heat dissipation holes 15 are arranged on the left and right sides of the heating tube 1203.

[0034] Specifically, the thermal pad 1201 is arranged in the placement groove 4, and its outer wall is tightly fitted with the inner wall of the placement groove 4 to maximize the contact area, thereby improving the heat conduction efficiency. The bottom of each thermal pad 1201 is connected to a thermal wire 1202, and the thermal wire 1202 is connected to the heating tube 1203, so that the heat generated by the heating tube 1203 can be evenly transferred to the sample bottle 13 in each placement groove 4, avoiding local accumulation of heat and effectively preventing the occurrence of overheating. The heat dissipation holes 15 opened on both sides of the body 1 and on both sides of the heating tube 1203 allow hot air to be quickly discharged while allowing cold air to enter, forming good air convection, thereby achieving efficient natural heat dissipation and improving the service life of the device.

[0035] Refer to the attached Figure 1 and attached Figure 2 The present invention provides an embodiment: a console 16 is fixedly connected to the front side of the body 1, a display screen 17 is fixedly connected to the top of the console 16, and a button 18 is provided at the bottom of the display screen 17; a warning sign 22 is fixedly connected to the top of the top cover 6, and pads 23 are fixedly connected to the four corners of the bottom of the body 1.

[0036] Specifically, the operation of the equipment is controlled by the console 16, a display screen 17 is provided to improve the user's interactive experience, and the operation is made simpler and faster by the button 18. A warning sign 22 is installed on the top of the top cover 6 to remind the operator to pay attention to safety. The four corners of the bottom of the body 1 are fixed with feet 23, which greatly increases the stability of the equipment and prevents the equipment from tilting due to uneven ground.

[0037] Working principle: After the sample is tested, there will be water stains in its placement slot 4, and long-term accumulation will form stains. At this time, when the instrument is used, the top cover 6 is covered, and the fixed column 9 set at the bottom of the top cover 6 enters the corresponding placement slot 4, and a circle of cleaning cotton 11 is set on the outer wall of the fixed column 9, so that the cleaning cotton 11 contacts the inside of the placement slot 4 to absorb the water stains therein to ensure the cleanliness of the placement slot 4. When strong stains that are difficult to absorb are generated, hold the limit block 20 tightly to move it up and down, thereby driving the slide rod 7 to slide in the slide groove 19 in the top cover 6, and finally through the connection between the fixed plate 8 and the fixed column 9, the cleaning cotton 11 can slide in the placement slot 4, thereby achieving the cleaning effect. When the cleaning cotton 11 is dirty, pull the cleaning cotton 11 off from the adhesive block 10 with force, and then replace it with a new cleaning cotton 11.

[0038] The sample to be tested is sucked into the sample bottle 13, covered with the bottle cap 14 and placed in the placement slot 4. The bottle body of the sample bottle 13 contacts the thermal pad 1201, and the heating tube 1203 is controlled to generate heat through the control console 16. The heat emitted by the heating tube 1203 is transferred to the corresponding thermal pad 1201 through the thermal wire 1202, and then transferred to the sample bottle 13, achieving uniform heating of the sample. The heat emitted by the device is dissipated through the heat dissipation hole 15.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
