[0022] The housing mechanism 1 further includes an arc-shaped limit plate 107, a compression spring 108, a sealing ring 109, an anti-collision groove 110, a trigger rod 111 and a spring groove 114.

[0023] Through the cooperation of the arc-shaped limit plate 107 and the limit ring groove 504, when installing the ceramic heating tube 501, the end cover 102 can be firstly pulled out from the surface of the heater housing 101 by removing the screws, and then the ceramic heating tube 501 can be placed in the interior of the heater housing 101. At this time, the pull rod 111 can be pulled outward to make the pull rod 111 drive the arc-shaped limit plate 107 to move to the inside of the spring groove 114. When the ceramic heating tube 501 is placed in the interior of the heater housing 101, When the trigger rod 111 is released, the arc-shaped limit plate 107 will be ejected by the elastic potential energy of the compression spring 108 and stuck into the inside of the limit ring groove 504, thereby fixing the mounting plate 502. At the same time, the surface of the mounting plate 502 will contact the surface of the sealing ring 109, and press the sealing ring 109 into the gap between the mounting plate 502 and the heater housing 101, thereby sealing the mounting plate 502, thereby preventing the mounting plate 502 from falling off and facilitating the replacement and maintenance of the ceramic heating tube 501.
[0024] The filtering mechanism 2 includes a filtering tube 201, a filtering net 202, a connecting outer tube 203 and an inserting inner tube 204. The outer ends of the water inlet 103 and the water outlet 104 are movably mounted with filtering tubes 201, and a plurality of filtering nets 202 are arranged inside the filtering tube 201.

The inserting inner tube 204 is movably inserted into the water inlet 103 and the water outlet 104.
[0025] By combining the filter tube 201 and the filter net 202, the device can filter the water entering the heater housing 101 and the water flowing out of the heater housing 101 through the filter net 202 when in use, thereby reducing impurities attached to the water flow and improving the purity of drinking water.
[0026] The temperature control mechanism 3 includes a temperature control switch 301, a connecting pressure piece 302, a series connector 303, a temperature control power cord 304 and a temperature control connector 305. The outer surface of the heater housing 101 is installed with a connecting pressure piece 302 by screws, and the temperature control switch 301 is provided at the center of the surface of the connecting pressure piece 302. The series connector 303 is movably connected to one end of the temperature control switch 301, and the outer end of the series connector 303 is connected to the temperature control power cord 304, and the outer end of the temperature control power cord 304 is connected to the temperature control connector 305.
[0027] The temperature sensing mechanism 4 includes an inlet temperature sensor 401, an outlet temperature sensor 402, an anti-dry-burning temperature sensor 403, a sensor power cord 404 and a sensor connector 405. The inlet temperature sensor 401 is movably connected inside the inlet socket 105, the outlet temperature sensor 402 is movably connected inside the outlet socket 106, the anti-dry-burning temperature sensor 403 is movably connected inside the dry-burning detection socket 112, the outer ends of the inlet temperature sensor 401, the outlet temperature sensor 402 and the anti-dry-burning temperature sensor 403 are all connected to the sensor power cord 404, and the outer ends of the sensor power cord 404 are all connected to the sensor connector 405.
[0028] By setting an anti-dry-burn temperature sensor 403 on the surface of the heater housing 101 near the water inlet 103, when the device is working normally, the temperature value fed back by the anti-dry-burn temperature sensor 403 is much lower than the water outlet temperature sensor 402. Once a flow interruption or cavity occurs, the temperature value fed back by the anti-dry-burn temperature sensor 403 will rise sharply or exceed the water temperature sensor 402. At this time, the overload power-off system can cut off the heating power supply of the heating mechanism 5 in the first time to achieve the anti-dry-burn function.
[0029] The heating mechanism 5 includes a ceramic heating tube 501, a mounting plate 502, a buffer cavity 503, a limiting ring groove 504, a ceramic tube power cord 505 and a ceramic tube joint 506. The ceramic heating tube 501 is movably inserted into the interior of the heater shell 101. The outer surface of the ceramic heating tube 501 is fixedly installed with a mounting plate 502. The mounting plate 502 is movably inserted into the position between the heater shell 101 and the end cover 102. A buffer cavity 503 is provided between the ceramic heating tube 501 and the interior of the heater shell 101. A limiting ring groove 504 is provided on the outer surface of the mounting plate 502. The surface of the ceramic heating tube 501 is connected to two ceramic tube power cords 505, and the outer ends of the two ceramic tube power cords 505 are connected to ceramic tube joints 506.
[0030] Through the cooperation between the ceramic heating tube 501 and the buffer chamber 503, when the device is in use, the buffer chamber 503 can reserve a steam polymerization area generated when water boils, thereby preventing the ceramic heating tube 501 from being dry due to the polymerization of a large amount of steam when water boils, causing the ceramic heating tube 501 to have an excessively large temperature difference, thereby reducing its service life or causing it to crack and fail.
[0031] The arc-shaped limit plates 107 are movably inserted into the limit ring grooves 504, and the sealing rings 109 are respectively fitted with the surfaces of the mounting plate 502, the water inlet temperature sensor 401, the water outlet temperature sensor 402 and the anti-dry-burning temperature sensor 403. A pressure relief valve 6 is provided inside the water exchange pipe 113, and a timing system is installed inside the pressure relief valve 6. The timing system is used to control the pressure relief valve 6 to drain water regularly.
[0032] By cooperating with the water exchange pipe 113 and the pressure relief valve 6, when the device is in use, the water exchange time can be set through the timing system installed in the pressure relief valve 6, so that the pressure relief valve 6 is opened at each set water exchange time interval, and the water accumulated in the heater housing 101 is discharged through the water exchange pipe 113, and the water exchange time is reset each time after the device is used, so as to avoid the situation where the water accumulated in the heater housing 101 breeds bacteria and affects the water quality and the cleanliness of the device when no water is discharged for a long time.
[0033] One of the ceramic tube joints 506 is connected to the temperature control switch 301 , and the temperature control switch 301 and the ceramic heating tube 501 are connected in series. A wire hole is provided on the outer surface of the end cover 102 , and the ceramic tube power line 505 passes through the wire hole and extends to the outside of the end cover 102 .
[0034] By connecting the temperature control switch 301 and the ceramic heating tube 501 in series, when the device is in use, when the anti-dry-burn temperature sensor 403 fails, the power supply of the heating mechanism 5 can be promptly cut off within the design temperature range through the temperature control switch 301, thereby realizing the dual anti-dry-burn protection of the anti-dry-burn temperature sensor 403 and the temperature control switch 301, ensuring that no serious dry-burn accidents will occur.
[0035] When the ceramic tube instant heating system for the direct drinking machine is in use, the device first installs the ceramic heating tube 501, first pulls out the end cover 102 from the surface of the heater housing 101 by removing the screws, and then puts the ceramic heating tube 501 into the interior of the heater housing 101. At this time, the pull rod 111 can be pulled to move outward, so that the pull rod 111 drives the arc-shaped limit plate 107 to move to the inside of the spring groove 114. When the ceramic heating tube 501 is placed in the interior of the heater housing 101, the pull rod 111 is released at this time, and the arc-shaped limit plate 107 will be ejected by the elastic potential energy of the compression spring 108 and stuck in the inside of the limit ring groove 504, thereby fixing the mounting plate 502. At the same time, the surface of the mounting plate 502 will contact the surface of the sealing ring 109, and the sealing ring 109 will be pressed into the gap between the mounting plate 502 and the heater housing 101, so as to achieve sealing of the mounting plate 502, thereby preventing the mounting plate 502 from falling off, and facilitating the replacement and maintenance of the ceramic heating tube 501. The water replacement time is set by the timing system installed inside the pressure relief valve 6, so that the device opens the pressure relief valve 6 at each set water replacement time interval, so that the water accumulated inside the heater housing 101 is discharged through the water replacement pipe 113, and the water replacement time is reset every time after the device is used, so as to avoid the situation where the water accumulated inside the heater housing 101 breeds bacteria when no water is discharged for a long time, thereby affecting the water quality and the cleanliness of the device; The buffer chamber 503 reserves a steam polymerization area generated when water boils, so as to prevent the ceramic heating tube 501 from being dry due to the polymerization of a large amount of steam when water boils, causing the ceramic heating tube 501 to have a large temperature difference, thereby reducing its service life or causing it to crack and fail; By arranging the anti-dry-burning temperature sensor 403 at a position near the water inlet 103 on the surface of the heater housing 101, when the device is working normally, the temperature value fed back by the anti-dry-burning temperature sensor 403 is much lower than the water outlet temperature sensor 402. Once a flow interruption or cavity occurs, the temperature value fed back by the anti-dry-burning temperature sensor 403 will rise sharply or exceed the water temperature sensor 402. At this time, the overload power-off system can cut off the heating power supply of the heating mechanism 5 in the first time, thereby realizing the anti-dry-burning function; When the anti-dry-burning temperature sensor 403 fails, the power supply of the heating mechanism 5 can also be promptly cut off by the temperature control switch 301 within the design temperature range, thereby realizing the dual anti-dry-burning protection of the anti-dry-burning temperature sensor 403 and the temperature control switch 301, ensuring that no serious dry-burning accident will occur; When water is entering and exiting, the water entering the heater housing 101 and the water flowing out of the heater housing 101 can be filtered through the filter net 202 to reduce impurities attached to the water flow and improve the purity of drinking water.
[0036] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
