Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example: Figure 1-8 As shown, this utility model provides a high-pressure water heating PTC heater assembly, including a housing 1, a fixing cover 11, a first pressure plate 12, a second pressure plate 13, and a heater body 2. The fixing cover 11 is movably disposed at the open end of the housing 1. The first pressure plate 12 is fixedly disposed on the lower surface of the fixing cover 11. The second pressure plate 13 is fixedly disposed on the bottom wall of the housing 1. The heater body 2 is movably disposed between the first pressure plate 12 and the second pressure plate 13. The heater body 2 includes a cover plate 21, a first water tank 22, a second water tank 23, a third water tank 24, a first heating element 25, a second heating element 26, an inlet pipe 27, and an outlet pipe 28. The first water tank 22, the second water tank 23, the third water tank 24, the first heating element 25, and the second heating element 26 are fixedly installed inside the cover plate 21. The first water tank 22 is connected to the inner cavity of the second water tank 23 and the third water tank 24 through pipes. The inlet pipe 27 and the outlet pipe 28 are connected to the inner cavity of the first water tank 22. The inlet pipe 27 and the outlet pipe 28 are located on one side of the outer shell 1. A lifting mechanism 3 is provided between the outer shell 1 and the fixed cover 11. By providing the lifting mechanism 3, the fixed cover 11 can be raised vertically, thereby separating the fixed cover 11 from the outer shell 1, so that the heater body 2 can be disassembled as a whole.

[0032] The lifting mechanism 3 includes an L-shaped fixing frame 31, which is fixedly mounted on one side of the outer casing 1. A lifting frame 32 is slidably mounted on the L-shaped fixing frame 31. One end of the lifting frame 32 is detachably mounted on the fixing cover 11. By driving the lifting frame 32 to rise and fall vertically, the lifting frame 32 can synchronously raise and lower the fixing cover 11, thereby allowing the fixing cover 11 to separate from or fit against the outer casing 1. A insertion groove 33 is provided on one side of the fixing cover 11. One end of the lifting frame 32 is movably inserted into the inner wall of the insertion groove 33. Several fixing bolts 34 are threadedly mounted on the upper surface of the fixing cover 11. Several threaded holes 35 are provided on one end of the lifting frame 32. One end of the fixing bolt 34 is threadedly connected to the inner wall of the threaded hole 35. By rotating the fixing bolt 34, the fixing bolt 34 can be moved to the inner wall of the outer casing 1. 4. Separating from the first threaded hole 35 allows the fixed cover 11 to separate from the lifting frame 32. A lead screw 36 is rotatably mounted on the L-shaped fixed frame 31. One end of the lead screw 36 is threadedly connected to the other end of the lifting frame 32. A hexagonal seat 37 is fixedly mounted on the other end of the lead screw 36. By manually rotating the hexagonal seat 37 (or by using a power tool), the hexagonal seat 37 can rotate the lead screw 36, which can drive the lifting frame 32 to rise and fall vertically. A guide rod 38 is fixedly mounted on the L-shaped fixed frame 31. A sliding sleeve 39 is slidably mounted on the guide rod 38. The other end of the lifting frame 32 is fixedly connected to the sliding sleeve 39. By setting the guide rod 38 and the sliding sleeve 39, the sliding sleeve 39 can slide vertically on the guide rod 38, thereby enabling the lifting frame 32 to maintain vertical rise and fall.

[0033] One end of the lower surface of the fixed cover 11 is fixedly provided with a first insert plate 4 and a second insert plate 41. One side of the outer shell 1 is provided with a first slot 51 and a second slot 52. The inner walls of the first insert plate 4 and the first slot 51 are movably connected. The outer wall of the water inlet pipe 27 is in movable contact with one end of the first slot 51. The inner walls of the second insert plate 41 and the second slot 52 are movably connected. The outer wall of the water outlet pipe 28 is in movable contact with one end of the second slot 52. When the fixed cover 11 rises vertically, the first insert plate 4 and the second insert plate 41 rise synchronously and separate from the first slot 51 and the second slot 52. When the heater body 2 is subsequently removed, the water inlet pipe 27 and the water outlet pipe 28 can be separated from the outer shell 1.

[0034] A third insert plate 42 is fixedly installed at the other end of the lower surface of the fixed cover 11, and a third slot 53 is provided on the other side of the outer shell 1. The inner walls of the third insert plate 42 and the third slot 53 are movably connected. The length of the third insert plate 42 is less than the depth of the third slot 53. By setting the third insert plate 42 and the third slot 53, when the fixed cover 11 rises vertically, the third insert plate 42 rises synchronously and disengages from the third slot 53. The setting of the third slot 53 allows for the power supply and signal line routing of the heater body 2.

[0035] A sealing gasket 43 is fixedly provided on the lower surface of the fixed cover 11. The lower surface of the sealing gasket 43 is in contact with the opening end of the outer shell 1. By providing the sealing gasket 43, the fixed cover 11 can be stably attached to the opening end of the outer shell 1.

[0036] A filter assembly 6 is provided at one end of the water inlet pipe 27. The filter assembly 6 includes a water inlet sleeve 61, one end of which is detachably installed on the water inlet pipe 27. A filter screen 62 is fixedly installed on the inner wall of the water inlet sleeve 61. By setting the water inlet sleeve 61 and the filter screen 62, heating water enters the water inlet pipe 27 through the water inlet sleeve 61 and the filter screen 62. The filter screen 62 can filter the heating water, filter out impurities in the water, and prevent impurities from entering the first water tank 22, the second water tank 23 and the third water tank 24, thereby reducing the maintenance frequency of the heater body 2 and increasing the service life of the heater body 2. A sealing ring 63 is fixedly installed at one end of the water inlet sleeve 61. The inner wall of the sealing ring 63 is in contact with the outer wall of the water inlet pipe 27. By setting the sealing ring 63, the sealing between the water inlet sleeve 61 and the water inlet pipe 27 can be improved, preventing the heating water from overflowing.

[0037] A number of fixing ears 64 are fixedly provided at one end of the water inlet sleeve 61. A locking screw 65 is rotatably installed on the fixing ears 64. A number of No. 2 threaded holes 66 are provided on the outer wall of the water inlet pipe 27. One end of the locking screw 65 is rotatably connected to the inner wall of the No. 2 threaded hole 66. By rotating the locking screw 65 into the No. 2 threaded hole 66, the water inlet sleeve 61 can be fixed on the water inlet pipe 27. At the same time, by rotating the locking screw 65 in the opposite direction, the water inlet sleeve 61 on the water inlet pipe 27 can be removed.

[0038] Working principle: Before the heater body 2 heats up, the operator first puts one end of the water inlet sleeve 61 onto the end of the water inlet pipe 27, and then rotates multiple locking screws 65 respectively, so that the threads of the ends of the multiple locking screws 65 enter the corresponding No. 2 threaded holes 66. At this time, the water inlet sleeve 61 and the filter screen 62 are fixed at the front end of the water inlet pipe 27.

[0039] When external heating water flows in through the inlet sleeve 61, the filter screen 62 filters the heating water, removing impurities and preventing them from entering the first water tank 22, the second water tank 23 and the third water tank 24 through the inlet pipe 27, thereby reducing the maintenance frequency of the heater body 2 and increasing its service life.

[0040] When maintenance is required on the heater body 2, the operator manually (or with a power tool) rotates the hexagonal base 37, which causes the lead screw 36 to rotate. The lead screw 36 drives the lifting frame 32 to rise vertically, which in turn causes the fixed cover 11 to rise vertically. The fixed cover 11 causes the first insertion plate 4 and the second insertion plate 41 to rise synchronously. Then, the heater body 2 can be removed from the outer casing 1, thus facilitating the disassembly of the heater body 2 and effectively improving the convenience of maintenance operations.

[0041] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0042] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
