Furthermore, it is inconvenient to filter water during boiler operation, and the boiling of water produces a large amount of scale that adheres to the inner wall of the boiler, requiring frequent maintenance and cleaning. Therefore, improvements are needed. Utility Model Content

Multiple support rods 2 are fixedly connected to the bottom of the boiler 1, evenly distributed at the bottom. These support rods 2 provide structural support for the boiler 1. A water outlet pipe 3 is fixedly connected to the left end of the boiler 1, and a water inlet pipe 4 is fixedly connected to the right end. A fixing seat 5 is fixedly connected to the top of the water inlet pipe 4, and a water inlet 6 is fixedly connected to the top of the fixing seat 5. An exhaust pipe 7 is fixedly connected to the top of the boiler 1, and a water tank 10 is fixedly connected to the outside of the exhaust pipe 7. The water tank 10 is fixedly connected to the boiler 1, and a magnetic cover 11 is attached to the inside of the water tank 10. An exhaust mechanism 8 is installed on the exhaust pipe 7, and a filter mechanism 9 is installed on the fixing seat 5.

[0024] Please see Figure 1 , Figure 2 , Figure 3 The exhaust mechanism 8 includes a connecting sleeve 81. The connecting sleeve 81 is fixedly sleeved on the outside of the exhaust pipe 7. A baffle 82 is slidably sleeved inside the connecting sleeve 81. A connecting rod 83 is fixedly connected to the bottom of the baffle 82. A sliding rod 84 is fixedly connected to the bottom of the connecting rod 83. The sliding rod 84 is slidably connected to the connecting sleeve 81. A guide rod 85 is slidably sleeved inside the sliding rod 84. The guide rod 85 is fixedly connected to the connecting sleeve 81. A first spring 86 is provided on the outside of the guide rod 85. One end of the first spring 86 is fixedly connected to the sliding rod 84, and the other end of the first spring 86 is fixedly connected to the connecting sleeve 81. By designing the first spring 86, the force of the first spring 86 can act on the sliding rod 84. By designing the exhaust mechanism 8, hot steam can be cooled and discharged.

[0025] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 The filtration mechanism 9 includes a connecting frame 91, which is slidably fitted inside the fixed base 5. A purification filter element 92 is installed inside the connecting frame 91. A connecting seat 93 is fixedly connected to the right end of the connecting frame 91. The connecting seat 93 is slidably connected to the fixed base 5. A guide rod 94 is slidably fitted inside the connecting seat 93. A second spring 95 is installed on the outside of the guide rod 94. One end of the second spring 95 is fixedly connected to the slider 96, and the other end of the second spring 95 is fixedly connected to the connecting seat 93. By designing the second spring 95, the force of the second spring 95 can act on the slider 96. The slider 96 is fixedly connected to the outside of the guide rod 94. The slider 96 is slidably connected to the connecting seat 93. A retaining ball 97 is movably fitted inside the slider 96. The retaining ball 97 is movably connected to both the connecting seat 93 and the fixed base 5. A groove 98 is opened inside the fixed base 5. The retaining ball 97 is movably fitted inside the groove 98. By designing the groove 98, the retaining ball 97 can roll inside the groove 98. By designing the filtration mechanism 9, water can be filtered and purified.

[0026] The specific implementation process of this utility model is as follows: When in use, water is added through the water inlet 6. After the water enters the fixed seat 5, it will fall on the surface of the purification filter element 92. Under the action of the purification filter element 92, the water can be filtered and purified, which can purify impurities in the water and greatly reduce the adhesion of scale inside the boiler 1 during combustion, eliminating the need for frequent maintenance of the boiler 1.

[0027] When the purification filter element 92 needs to be disassembled, simply pull the connecting seat 93 horizontally. The connecting seat 93 will move the connecting frame 91 horizontally, and at the same time, the connecting seat 93 will move the retaining ball 97 horizontally. The retaining ball 97 can roll along the arc surface of the groove 98. The retaining ball 97 will be squeezed and pushed to move vertically. The retaining ball 97 will roll into the connecting seat 93. The retaining ball 97 will move the slider 96 and the guide rod 94. The slider 96 can squeeze the second spring 95, which can separate the retaining ball 97 from the groove 98. Then the connecting seat 93 and the connecting frame 91 can be pulled out from the fixed seat 5 for easy replacement of the purification filter element 92.

[0028] During the combustion process of boiler 1, when the internal gas pressure of boiler 1 is high, the gas will be output through exhaust pipe 7. The gas will push the baffle 82 to move down. The baffle 82 will drive the connecting rod 83 and the sliding rod 84 to move down. The sliding rod 84 will slide along the guide rod 85 and squeeze the first spring 86, causing the baffle 82 to separate from the inner wall of the connecting sleeve 81. At this time, the gas will be discharged through the gap between the baffle 82 and the connecting sleeve 81. The hot steam will enter the water inside the water tank 10, which can cool the steam and prevent the high-temperature hot steam from being directly discharged and causing danger to the human body. It can also prevent burns to the human body and avoid affecting the working environment temperature. In addition, during the exhaust process, the baffle 82 can achieve one-way gas discharge and prevent water from flowing back into the exhaust pipe 7.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
