[0002] A water heater is a device that uses various physical principles to raise the temperature of cold water into hot water within a certain period of time. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic water heaters, air water heaters, gas water heaters, etc. The smoke pipe of the water heater can discharge gas out of the room, maintain effective ventilation, and effectively avoid accidents such as gas poisoning.

[0003] However, in the prior art, during the installation of traditional smoke pipes, it is necessary to purchase steel hoops to fix the pipe interfaces. Without the steel hoops, the pipe interfaces cannot be fixed, resulting in the inability of workers to quickly fix the smoke pipes on the water heater. In addition, in traditional smoke pipes, a foaming agent needs to be used to seal the pipes and the smoke exhaust ports, which increases the use cost. Utility Model Content

[0030] The outer wall of the knob 24 contacts the outer wall of the limit plate 23, the top of the fixing hoop 21 is fixedly connected to the bottom of the bellows 1, the sealing mechanism 5 includes a fixing ring 51, the inner wall of the fixing ring 51 is fixedly connected to an air pipe 54, the air pipe 54 passes through the fixing ring 51, and is connected to the inside of the airbag 52, the outer wall of the fixing ring 51 is fixedly connected to the airbag 52.

[0031] The inner wall of the airbag 52 is fixedly connected to the outer wall of the air pipe 54, the bottom of the fixing ring 51 is fixedly connected to the bottom of the corrugated tube 1, the outer wall of the fixing ring 51 is fixedly connected to the limiting ring 55, the outer wall of the limiting ring 55 contacts the outer wall of the airbag 52, and the outer wall of the airbag 52 is fixedly connected to the anti-slip ring 53, the anti-slip ring 53 is used to increase the contact area between the airbag 52 and the wall, and the anti-slip ring 53 is linearly arrayed along the outer wall of the airbag 52.

[0032] Working principle:

[0033] When in use, first assemble the scattered smoke pipe components into a complete smoke pipe. It is only necessary to install the corrugated pipe 1 on the mounting base 3 to form a complete smoke pipe, and then install the mounting base 3 at the bottom of the smoke pipe on the water heater. When installing the mounting base 3 on the water heater, it is necessary to align the end of the mounting base 3 with the sealing ring 4 with the water heater, and then insert the mounting base 3 into the water heater. After the mounting base 3 is installed in the water heater, the sealing ring 4 at the interface prevents smoke from leaking from the interface. After the smoke pipe is installed on the water heater, then insert the top of the smoke pipe into the smoke exhaust port on the wall. It should be noted that the sealing mechanism 5 at the top of the smoke pipe should be in the smoke exhaust port, and then inflate the sealing mechanism 5 to expand the sealing mechanism 5, thereby blocking the smoke exhaust port.

[0034] Before installing the bellows 1 on the mounting seat 3, it is necessary to loosen the mounting mechanism 2 first, that is, turn the knobs 24 at both ends of the double-headed screw 25 so that the knobs 24 are at the extreme edge of the double-headed screw 25, and the extreme edge is the head and tail of the double-headed screw 25. When the knob 24 is at the extreme edge, the top spring 26 lacks the pressure of the limit plate 23, thereby releasing the elastic potential energy, so that the two limit plates 23 on the fixing hoop 21 are separated from each other, thereby expanding the diameter of the fixing hoop 21, and then the fixing hoop 21 is inserted into the end of the mounting seat 3 away from the sealing ring 4. After the fixing hoop 21 is inserted After the mounting seat 3 is installed, the knobs 24 on both sides of the double-headed screw 25 are rotated to make the knobs 24 approach each other and compress the limit plate 23, thereby driving the fixing hoop 21 to move synchronously, so as to reduce the diameter of the fixing hoop 21. A positioning ring 27 is connected to the fixing hoop 21. Therefore, under the restriction of the positioning ring 27, the fixing hoop 21 can only move along the positioning ring 27, and then the fixing hoop 21 is fixed on the mounting seat 3. A guard plate 22 is provided at the interface of the fixing hoop 21. Therefore, under the obstruction of the guard plate 22, the smoke leakage from the interface of the fixing hoop 21 can be reduced.

[0035] When the sealing mechanism 5 is fixed to the smoke exhaust port, it is necessary to keep the sealing mechanism 5 in the smoke exhaust port, and then blow air into the air pipe 54 to allow the gas to be transported to the airbag 52 through the air pipe 54. After the continuous entry of gas, the airbag 52 expands. Under the restriction of the limiting rings 55 on both sides, the expanded airbag 52 can only expand in the direction away from the fixing ring 51. After the airbag 52 continues to expand, the anti-slip ring 53 on the surface of the airbag 52 first contacts the wall of the smoke exhaust port. The deformation of the anti-slip ring 53 increases the contact area between the airbag 52 and the wall, thereby preventing the airbag 52 from slipping out of the smoke exhaust port. After the anti-slip ring 53 is completely against the wall, stop transporting gas into the air pipe 54, and block the air pipe 54, thereby preventing the gas in the airbag 52 from leaking from the air pipe 54 to the outside.

[0036] After the air pipe 54 is used, it is only necessary to release the blocked air pipe 54 so that the gas in the air bag 52 can flow from the air pipe 54 to the outside, thereby shrinking the air bag 52 and releasing the fixation of the air bag 52 to the wall. Then the smoke pipe can be taken out from the smoke exhaust port.

[0037] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
