Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] Embodiment one

[0027] Reference Figures 1-4 An environment-friendly resistance furnace, comprising a main assembly 1; the main assembly 1 comprises a resistance furnace body 11, the front surface of which is hingedly connected with a furnace door 12; an air inlet pipe 13 is arranged on the outer side wall of the resistance furnace body 11; a purification assembly 2 is arranged on the resistance furnace body 11; the purification assembly 2 comprises a mounting plate 21 fixedly connected to the rear surface of the resistance furnace body 11; a purification box one 22 fixedly connected to the top of the mounting plate 21; a purification box two 23 fixedly connected to the top of the mounting plate 21; a U-shaped pipe 24 inserted into the interior of the purification box one 22 and inserted into the interior of the purification box two 23; a water inlet pipe 25 inserted into the top of the purification box two 23 and the top of the purification box one 22; an air outlet pipe 26 inserted into the interior of the purification box one 22; an air inlet mechanism 27 arranged on the resistance furnace body 11; the air inlet mechanism 27 comprises a fan 271 fixedly connected to the top of the mounting plate 21, and the air outlet pipe 26 is fixedly connected to the air outlet of the fan 271; an air inlet pipe 272 fixedly connected to the air inlet of the fan 271 and inserted into the interior of the resistance furnace body 11; one end of the air outlet pipe 26 and one end of the U-shaped pipe 24 are fixedly connected with a pipe body 4, and a plurality of through holes are formed in the surface of the pipe body 4.

[0028] In use, the operator places the resistance furnace body 11 in the designated position, then opens the furnace door 12, places the workpiece for processing, and after processing is completed, the operator sends gas into the gas outlet pipe 26 through the air inlet mechanism 27, and ensures the internal pressure of the resistance furnace body 11 through the air inlet pipe 13 with a one-way valve. The gas entering the gas outlet pipe 26 is sent into the purification tank one 22 on the mounting plate 21, and the harmful gas is purified through the absorption liquid inside the purification tank one 22. Then the purified gas enters the purification tank two 23 through the U-shaped pipe 24 for the second purification, ensuring the purification effect of the device. Then the purified gas is discharged through the gas outlet pipe at the top of the purification tank two 23. After use, the operator discharges the purification liquid through the water outlet at the bottom of the purification tank one 22 and the purification tank two 23, and injects new purification liquid through the water inlet pipe 25, thereby avoiding the harm of harmful gas to the environment and the health of workers, and improving the safety of the device. The operator opens the fan 271, and the fan 271 draws the gas inside the resistance furnace body 11 through the air inlet pipe 272 and sends it into the gas outlet pipe 26, which is simple to operate and improves the convenience of the device. When the gas enters the purification tank one 22 and the purification tank two 23 through the gas outlet pipe 26 and the U-shaped pipe 24, the diffusion degree of the gas in the purification liquid can be increased through the multiple through holes on the pipe body 4, thereby avoiding the gas being too concentrated in a certain position and affecting the purification effect when the flow rate is too high, thereby improving the practicality of the device.

[0029] Example two

[0030] Referring to Figures 1-4 On the basis of example one, the water changing function is added;

[0031] The resistance furnace body 11 is provided with a water changing assembly 3, which comprises: a water tank 31 fixedly connected to the top of the resistance furnace body 11; a water pump 32 fixedly connected to the top of the resistance furnace body 11, and the water inlet is inserted into the inside of the water tank 31; a water supply pipe 33 fixedly connected to the rear surface of the water tank 31, and the water outlet of the water pump 32 is inserted into the inside of the water supply pipe 33; an L-shaped pipe 34, one end of each water inlet pipe 25 is fixedly connected with an L-shaped pipe 34, and the other end of each L-shaped pipe 34 is inserted into the inside of the water supply pipe 33; the purification tank two 23 and the purification tank one 22 are provided with a water level sensor 5, and the water level sensor 5 is electrically connected with the water pump 32; the inside bottom surface of the purification tank two 23 and the purification tank one 22 is provided as an inclined surface.

[0032] When the new purification liquid needs to be replaced, the operator opens the water pump 32, so that the water pump 32 draws the purification liquid in the water tank 31 into the water delivery pipe 33, and through the two L-shaped pipes 34, the purification liquid enters the purification tank one 22 and the purification tank two 23 respectively, without the operator needing to fill the purification tank one 22 and the purification tank two 23 respectively, thereby improving the practicality of the device; when the purification liquid in the purification tank one 22 and the purification tank two 23 is filled to an appropriate degree, the water level sensor 5 transmits an electric signal to the distribution box, the distribution box transmits the electric signal to the controller, the controller transmits the electric signal to the water pump 32, and then the water pump 32 is automatically closed, and the purification tank one 22 and the purification tank two 23 are no longer filled, avoiding the inconvenience of the operator checking the filling degree of the purification tank one 22 and the purification tank two 23, which causes the purification liquid to be spilled and wasted, thereby improving the convenience of the device; the purification liquid in the purification tank two 23 and the purification tank one 22 can flow to the water outlet through the inclined surface thereof, thereby reducing the residual purification liquid in the purification tank one 22 and the purification tank two 23, and further ensuring the purification effect of the newly filled purification liquid in the purification tank one 22 and the purification tank two 23.

[0033] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
