[0021] First, place the device to a suitable position, place the PTC water heater to a position in contact with the left end face of the second clamping plate 22, and turn the adjusting rod 7 upwards. The adjusting rod 7 drives the flip plate 8 to rotate, and the flip plate 8 drives the first clamping plate 16 connected to the clamping component to move to a position close to the PTC water heater, so that the first clamping plate 16 and the second clamping plate 22 can quickly fix the position of the PTC water heater on the partition plate 2; a fixed shaft is rotatably connected in the ear plate, and the fixed shaft is fixedly connected to the flip plate 8. A snap ring 23 with an opening on one side is mounted on the front end of the fixed shaft, and the lower side of the snap ring 23 is fixedly connected to the ear plate. A locking rod 24 is threadedly connected to the upper and lower parts of the right side of the snap ring 23. When it is necessary to fix the fixed shaft in the position of the ear plate, the snap ring 23 is fixed to the position of the fixed shaft in the ear plate by rotating the locking rod 24, thereby fixing the position of the flip plate 8 after adjustment.

[0022] The clamping component includes a first connecting rod 9 hinged on the upper side of the flip plate 8, a movable plate 10 hinged on the lower side of the first connecting rod 9, push rods 12 fixedly connected on both sides of the movable plate 10, the two push rods 12 are slidably connected with a clamping top plate 14, the clamping top plate 14 is fixedly connected to the first clamping plate 16, a first tension spring 11 is fixedly arranged on the front side of the movable plate 10, the other end of the first tension spring 11 is fixedly connected to the clamping top plate 14, and the first tension spring 11 is sleeved on the outside of the push rod 12.

[0023] Place one side of the PTC water heater in contact with the left end surface of the second clamping plate 22, and rotate the adjusting rod 7 upwards to drive the flip plate 8 to rotate. Since the first connecting rod 9 is hinged on the upper side of the flip plate 8 and the movable plate 10 is hinged on the lower side of the first connecting rod 9, the movable plate 10 is driven to move horizontally to the right along the partition, and then the first clamping plate 16 is moved toward the direction of the PTC water heater. The position of the PTC water heater on the partition plate 2 is fixed by the first clamping plate 16 and the second clamping plate 22; the first tension spring 11 serves to limit the displacement of the clamping top plate 14 toward the direction of the PTC water heater, thereby preventing the PTC water heater from being fixed and clamped by the first clamping plate 16 and the second clamping plate 22.

[0024] A T-shaped limiting rod 15 is fixedly connected to the right end of the backing plate 13 . The clamping top plate 14 is provided with a limiting groove 17 . The T-shaped limiting rod 15 is inserted into the limiting groove 17 and moves freely along the length direction of the limiting groove 17 .

[0025] By using the T-shaped limiting rod 15 in cooperation with the limiting groove 17 , the clamping top plate 14 is moved horizontally to the left and right sides, so that the clamping top plate 14 can fix the position of the PTC water heater on the upper side of the partition plate 2 .

[0026] The lock plate 18 has hanging ears fixedly connected on both sides, and connecting posts 19 are inserted into the hanging ears. The connecting posts 19 are fixedly connected to the box body 1, and second tension springs are sleeved on the outer sides of the connecting posts 19. A pressing plate 20 is fixedly arranged on the lower side of the lock plate 18.

[0027] When it is necessary to open the lower cavity, the pressing plate 20 is pressed downward, and the pressing plate 20 drives the locking plate 18 to move downward. At this time, the second tension spring is in a compressed state due to the external force, and when the upper end position of the locking plate 18 moves to the lower position of the bottom plate of the cover plate 4, it is convenient to flip the cover plate 4, thereby opening the lower cavity; when it is necessary to close the lower cavity, the position of the pressing plate 20 is released, and under the action of the second tension spring, the locking plate 18 moves upward, thereby making the locking plate 18 contact the outer side of the cover plate 4, limiting the opening of the cover plate 4 to the outside.

[0028] The lower side of the connecting column 19 is fixedly connected to a limiting cap 21, and the limiting cap 21 is located at the lower part of the hanging ear.

[0029] The limiting cap 21 limits the downward movement of the hanging ear along the connecting column 19 .

[0030] The partition plate 2 is provided with a long strip groove 3 for connecting the upper cavity with the lower cavity.

[0031] A water supply device is placed in the lower cavity, and the water supply device is connected to the heating device of the partition plate 2 through a connecting pipe passing through the long strip groove 3.

[0032] A plurality of evenly distributed universal wheels 5 are fixedly arranged at the lower end of the box body 1 .

[0033] The universal wheel 5 has a self-braking feature, which facilitates the movement and fixation of the device.

[0034] When the utility model is in use, firstly, one side of the PTC water heater is placed in contact with the position of the left end face of the second clamping plate 22, and the adjusting rod 7 is rotated upward, and the adjusting rod 7 drives the flip plate 8 to rotate. Since the first connecting rod 9 is hinged on the upper side of the flip plate 8, and the movable plate 10 is hinged on the lower side of the first connecting rod 9, the movable plate 10 is driven to move horizontally to the right along the partition, and then the first clamping plate 16 is moved toward the direction of the PTC water heater, and the position of the PTC water heater on the partition plate 2 is fixed by the first clamping plate 16 and the second clamping plate 22.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
