[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Refer to Figures 1-3 , an embodiment provided by the present invention: A liquid flash point tester includes a body 1, a drying pump 3 is fixedly connected to the upper part of the body 1, a stop valve 4 is fixedly connected to one side of the drying pump 3, an operating table 2 is arranged on the front side of the body 1, a radiator fan 10 is fixedly connected to the rear side of the body 1, a water tank 5 is slidably connected inside the body 1, a connecting block 7 is fixedly connected to the outside of the water tank 5, an observation window 8 is arranged in the middle of the body 1, a circulation tank 16 is fixedly connected inside the body 1, an input pipe 17 is fixedly connected to the upper part of the circulation tank 16, an output pipe 11 is fixedly connected to one side of the circulation tank 16, a valve 12 is arranged inside the output pipe 11, a water pump 14 is fixedly connected inside the body 1, the output end of the water pump 14 is fixedly connected inside the circulation tank 16, the output end of the circulation tank 16 is fixedly connected with a circulation water pipe 15, and the other end of the circulation water pipe 15 is fixedly connected to the input end of the water pump 14. A quantitative component is arranged inside the input pipe 17. The quantitative component includes a floating plate 19, the floating plate 19 is slidably connected inside the input pipe 17, a limit block 20 is fixedly connected to the outer periphery of the floating plate 19, a limit groove 18 is opened in the middle of the input pipe 17, the limit block 20 is slidably connected in the limit groove 18, and a water trough 21 is opened inside the input pipe 17.

[0034] Specifically, the device is a flash point measuring instrument for liquid pesticides, mainly testing its safety. For the accuracy and convenience of detection, a corresponding drying pump 3 is provided after draining the liquid. A stop valve 4 is provided at the drying pump 3. While having relatively high safety, it is easy to identify the working state of the drying pump 3. The body 1 is used to detect the flash point of the pesticide. The operation console 2 is used for ignition and recording the flash point temperature. The radiator fan 10 is used to dissipate the heat generated by the device. The water tank 5 is used to place the pesticide to be detected. The connecting block 7 is used to connect the hose for convenient input of the pesticide. The observation window 8 is used to conveniently observe the internal situation of the device. The circulation tank 16 is used to hold the coolant, and the water pump 14 is used to pump the coolant so that the coolant can circulate in the circulation water pipe 15 to accelerate heat dissipation. The floating plate 19 is used to control whether the coolant in the coolant tank 9 flows into the circulation tank 16. When the coolant in the circulation tank 16 decreases, the floating plate 19 will drop, and the liquid in the coolant tank 9 will flow from the water trough 21 into the circulation tank 16. When the liquid is sufficient, it will lift the floating plate 19 to block the input pipe 17. The limit block 20 and the limit groove 18 cooperate to prevent the floating plate 19 from tilting during the lifting and lowering process, causing all the coolant to enter the circulation tank 16. The water trough 21 is used to allow the coolant in the coolant tank 9 to enter the circulation tank 16. The output pipe 11 and the valve 12 are used to conveniently extract the internal coolant when the device is not in use.

[0035] Refer to Figures 1-3 , a handle 6 is fixedly connected to the outside of the water tank 5, and a disassembly component is provided in the middle of the water tank 5. The disassembly component includes a clamping block 22, the clamping block 22 is slidably connected to the middle of the water tank 5, a compression spring 23 is fixedly connected between the clamping block 22 and the water tank 5, a chute 24 is opened in the middle of the water tank 5, a lever 13 is fixedly connected to one side of the clamping block 22, the lever 13 is slidably connected inside the chute 24, and the clamping block 22 is slidably connected inside the body 1.

[0036] Specifically, the handle 6 is used to conveniently pick up the water tank 5, the clamping block 22 is used to clamp inside the body 1 to fix the water tank 5, and the compression spring 23 is used to squeeze the clamping block 22 so that it clamps inside the body 1. The lever 13 is used to conveniently move the clamping block 22, and the chute 24 is used to limit the movement track of the lever 13.

[0037] Refer to Figures 1-3 , the circulation water pipe 15 is fixedly connected inside the body 1, and a coolant tank 9 is fixedly connected to the outer periphery of the input pipe 17. The output pipe 11 is fixedly connected inside the body 1, and the coolant tank 9 is slidably connected to the upper part of the body 1. An igniter is provided inside the body 1, the connecting block 7 is fixedly connected with a hose, and the hose abuts inside the stop valve 4. The material used for the observation window 8 is transparent glass.

[0038] Specifically, the circulating water pipe 15 is attached to the inner wall of the machine body 1 for easy heat absorption. The coolant tank 9 is used to hold the coolant. The igniter is used to detect the flash point of the pesticide. When detecting, the stop valve 4 is closed; when draining, the stop valve 4 is opened. The transparent glass facilitates observation.

[0039] Working principle: During the operation, the pesticide to be tested is placed in the water tank 5. The igniter is activated to ignite the pesticide and record its flash point temperature. The coolant is stored in the circulation tank 16 and is pumped by the water pump 14 and accelerated for heat dissipation through the circulating water pipe 15. The floating plate 19 controls the flow of the coolant. When the coolant in the circulation tank 16 decreases, the floating plate 19 drops, causing the coolant to enter the circulation tank 16 from the water trough 21. When the liquid level is sufficient, the floating plate 19 is lifted to prevent further liquid flow. The disassembly components such as the clamping block 22 and the lever 13 facilitate the maintenance of the water tank 5, while the observation window 8 of the transparent glass facilitates the observation of the internal situation. Overall, the device tests the flash point of the liquid pesticide by ignition and uses the coolant and the heat dissipation system to ensure that the device safely, accurately and conveniently completes the testing process.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
