The disassembly mechanism includes a knob 13 rotatably connected to one side of the heater body 1, and two groups of knobs 13 are provided.

[0031] The present utility model will be further described below in conjunction with the embodiments.

[0032] Embodiment 1:

[0033] To solve the problem that most of the existing liquid heaters are of an integrated structure, when the internal heating pipe 12 is damaged or the like, it is not convenient to maintain it, and the whole device often needs to be replaced, which is not conducive to use. Therefore, the following solution is disclosed. Specifically, please refer to Figures 1 - 3, a water inlet pipe 121 is fixedly connected to the bottom of the heating pipe 12, an installation block 122 is fixedly connected to the bottom of the water inlet pipe 121, a first bevel gear 131 is fixedly connected to one side of the knob 13, a second bevel gear 132 is meshed and connected to one side of the first bevel gear 131, a left - and - right - hand threaded lead screw 133 is fixedly connected to one side of the second bevel gear 132, and a clamping hoop 134 is threadedly connected to the outer side of the left - and - right - hand threaded lead screw 133. The clamping hoop 134 is slidably connected inside the heater body 1. A connecting pipe 14 is fixedly connected to one side of the heater body 1, and one end of the connecting pipe 14 extends into the heater body 1 and is provided with an installation groove 141. The installation groove 141 is slidably matched with the installation block 122. When the heating pipe 12 inside the heater body 1 is damaged, the top cover 2 can be removed from the top of the heater body 1 at this time, and the knob 13 is rotated. The knob 13 drives the first bevel gear 131 to rotate, thereby causing the second bevel gear 132 to rotate. The second bevel gear 132 drives the left - and - right - hand threaded lead screw 133 to rotate, thereby causing the two clamping hoops 134 to move. At this time, the installation block 122 at the bottom of the water inlet pipe 121 can be separated from the installation groove 141 on the connecting pipe 14, and then the heating pipe 12 can be taken out from the inside of the heater body 1. When installation is required, the installation block 122 at the bottom of the water inlet pipe 121 is aligned with the installation groove 141 and placed in, and then the knob 13 is rotated to make the two clamping hoops 134 align with the water inlet pipe 121 and the connecting pipe 14 for connection. Finally, the limiting rod 21 at the bottom of the top cover 2 is aligned with the limiting groove 11 and placed in, achieving the function of being able to separately take out the heating pipe 12 for maintenance or replacement, improving the use efficiency.

[0034] Embodiment 2:

[0035] To solve the problem that most existing liquid heaters do not have the function of filtering liquid. After long - term use, it is inevitable that the heating pipe 12 will be damaged by impurities in the liquid, affecting the working life. Therefore, the following solution is disclosed. For details, please refer to Figure 2 , Figure 4 and Figure 5, a connection box 15 is fixedly connected to the outside of the connecting pipe 14. A connection groove 151 is formed on one side of the connection box 15. A filter screen frame 152 is detachably arranged inside the connection groove 151. A first spring 153 is fixedly connected inside the connection groove 151. One end of the first spring 153 is fixedly connected to an ejecting block 154. A lever 16 is slidably connected to one side of the connection box 15. A second spring 161 is fixedly connected to the top of the lever 16. The other end of the second spring 161 is fixedly connected inside the connection box 15. A trapezoidal block 162 is fixedly connected to the bottom end of the lever 16. A fixing groove 163 is formed on the top of the filter screen frame 152. The fixing groove 163 is in sliding fit with the trapezoidal block 162. When an external pipeline is connected to the inside of the connecting pipe 14, at this time, the liquid moves inside the connecting pipe 14, passes through the connection box 15, and enters the inside of the heating pipe 12 for work through the filtering effect of the filter screen frame 152. When it is necessary to clean the filter screen frame 152, at this time, the lever 16 can be toggled. The lever 16 drives the trapezoidal block 162 to move, so that the trapezoidal block 162 disengages from the inside of the fixing groove 163. At this time, under the action of the first spring 153, the ejecting block 154 ejects the filter screen frame 152 from the inside of the connection groove 151. At this time, the filter screen frame 152 can be cleaned. When installing, after placing the filter screen frame 152 inside the connection groove 151 and moving it, the fixing groove 163 on the filter screen frame 152 is engaged with the trapezoidal block 162, achieving the effect of being able to filter the liquid, and at the same time facilitating the cleaning of the filter screen frame 152.
