[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 and Figure 2The utility model provides an embodiment: an electric boiler liquid heater, comprising a fixed shell 1, the outer wall of the fixed shell 1 is provided with vertical grooves 3 all around, the inner top wall of the fixed shell 1 is fixedly connected with a hydraulic rod 4, the output end of the hydraulic rod 4 is fixedly connected with a cross rod 5, the vertical grooves 3 are passed through the cross rod 5 all around and are fixedly connected with a displacement shell 6, a protective shell 7 is arranged at the bottom of the displacement shell 6, PTC heating elements 8 are fixedly installed on the left and right sides of the bottom wall of the fixed shell 1, the bottom ends of the two PTC heating elements 8 are fixedly connected with a temperature conduction device 9, and a sealing ring 10 is fixedly installed on the bottom wall of the protective shell 7; the front and rear sides of the top wall of the protective shell 7 are fixedly connected with sealing plates 206, the front and rear sides of the bottom wall of the displacement shell 6 are provided with sealing grooves 207, and the top walls of the two sealing plates 206 are respectively engaged with the corresponding sealing grooves 207;

[0030] Specifically, by starting the hydraulic rod 4, the cross rod 5 is driven to move. The displacement shell 6 and the protective shell 7 are displaced synchronously. As the displacement shell 6 and the protective shell 7 move, the two PTC heating elements 8 fixedly installed at the bottom of the fixed shell 1 are exposed. This design allows maintenance personnel to directly check the status of the PTC heating element 8 without disassembling the heater. This greatly shortens the maintenance time and improves work efficiency. After the inspection is completed, the displacement shell 6 and the protective shell 7 are lowered to the appropriate position through further displacement of the hydraulic rod 4. At this time, the sealing ring 10 is engaged with the temperature conduction device 9 to ensure that the outside of the heater is tightly sealed. The completion of this step marks the end of the heater maintenance process, and also ensures the safety and stability of the heater during subsequent operation. By adopting this innovative maintenance method, not only can the maintenance cost of the heater be reduced, but also the efficient operation of the equipment can be ensured. Without the need to disassemble the heater, maintenance personnel can quickly and accurately inspect and maintain the PTC heating element 8, thereby avoiding production delays caused by disassembly. The sealing ring 10 can increase the sealing performance between the protective shell 7 and the temperature conduction device 9. The top walls of the two sealing plates 206 are respectively engaged with the corresponding sealing grooves 207, thereby effectively increasing the sealing performance between the displacement shell 6 and the protective shell 7.

[0031] Reference Figure 1 and Figure 3 The top wall of the protective shell 7 is provided with a connecting mechanism 2, which includes two return springs 201, and the adjacent sides of the two return springs 201 are respectively fixedly connected to the left and right inner walls of the protective shell 7, and the two return springs 201 are fixedly connected to the sides away from each other with a movable plate 202, and the two movable plates 202 are provided with two engaging grooves 203 on the sides away from each other, and the two movable plates 202 are fixedly connected to the sides away from each other with a movable column 204, and the left and right sides of the bottom wall of the displacement shell 6 are fixedly connected with two engaging plates 205, and the multiple engaging plates 205 are respectively engaged with the corresponding engaging grooves 203;

[0032] Specifically, it is necessary to press the two movable columns 204 so that the movable plate 202 is acted upon by a force. As the movable plate 202 moves, the multiple snap-fit ​​plates 205 are disengaged from the corresponding snap-fit ​​grooves 203. This design greatly facilitates the disassembly of the protective shell 7. The disassembly work can be easily completed by simply pulling the protective shell 7. Such a design allows maintenance personnel to easily replace the protective shell 7 to ensure the normal operation of the heater. At the same time, this design also extends the service life of the heater and reduces the risk of equipment failure. By designing the movable column 204 and the movable plate 202, the operability of the equipment is significantly improved. The operator can easily disassemble and replace the protective shell 7 when necessary, which not only improves the reliability and service life of the equipment, but also greatly improves the convenience of operation.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A control switch 11 is fixedly connected to the top wall of the fixed shell 1, and the control switch 11 is electrically connected to the hydraulic rod 4 and the PTC heating element 8 respectively; a protective shell 12 is arranged on the top of the control switch 11, and the rear side of the protective shell 12 is rotatably connected to the top wall of the fixed shell 1 through a hinge;

[0034] Specifically, through the control switch 11 electrically connected to the hydraulic rod 4 and the PTC heating element 8 respectively, the control switch 11 can complete the opening and closing of the heater, and the protective shell 12 can protect the control switch 11 and prevent accidental touch.

[0035] Reference Figure 1 The left and right sides of the front top wall of the fixed shell 1 are fixedly connected with connecting plates 13; the four corners of the inner wall of the displacement shell 6 are fixedly installed with cleaning sponge blocks 14;

[0036] Specifically, the two connecting plates 13 facilitate installation of the heater, and the plurality of cleaning sponge blocks 14 enable the outer wall of the fixed shell 1 to be cleaned by displacement of the displacement shell 6 .

[0037] Working principle: When starting daily inspection, the hydraulic rod 4 is started to make the cross rod 5 start to move, and then the displacement shell 6 and the protective shell 7 fixedly connected by multiple vertical grooves 3 are displaced together, so that the two PTC heating elements 8 fixedly installed on the bottom of the fixed shell 1 are exposed, and then the inspection of the PTC heating element 8 can be completed without disassembling the heater. After the inspection is completed, the displacement shell 6 and the protective shell 7 are lowered by the displacement of the hydraulic rod 4, and the sealing ring 10 is engaged with the temperature conduction device 9, so as to achieve the purpose of closing the outside of the heater, thereby avoiding the time required for disassembly for maintenance and improving the working efficiency of the heater. By pressing the two movable columns 204, the two movable plates 202 are subjected to the force of the two movable columns 204 and then displaced together, so that the multiple engaging plates 205 are disengaged from the corresponding engaging grooves 203, and then the protective shell 7 is pulled, so as to achieve the purpose of disassembling the protective shell 7, so that the protective shell 7 can be replaced, thereby extending the service life of the heater and improving the flexibility of the device.
