Therefore, the instant heating type heating pipe, the temperature control assembly, the water pump and the control panel assembly are integrated together by only utilizing one mounting seat, the positions of all the components are relatively fixed, the structure is very compact, the length of a connecting wire can be shortened, the wiring inside the liquid heating container is simplified, all the components can be mounted and fixed on the mounting seat in advance, and then the components are placed into the main shell, so that the mounting operation is simplified.

Furthermore, the temperature control assembly comprises a first temperature sensing switch capable of automatically resetting and a second temperature sensing switch capable of manually resetting, wherein the first temperature sensing switch and the second temperature sensing switch can respectively and independently control the on/off of the instant heating pipe, and the temperature sensing ends of the first temperature sensing switch and the second temperature sensing switch are tightly attached to the outer wall of the instant heating pipe. Therefore, the first temperature-sensing switch and the second temperature-sensing switch on the instant heating type heating pipe and the temperature control component are all integrated on the mounting base, so that the first temperature-sensing switch and the second temperature-sensing switch are integrated into an integrated module, and the assembly is simple.

Furthermore, the temperature control assembly further comprises a shell, and a first electric conductor and a second electric conductor which are arranged in the shell, wherein two ends of the first electric conductor and two ends of the second electric conductor both extend out of the shell, one end of the first electric conductor and one end of the second electric conductor are respectively connected with two poles of the instant heating pipe in a clinging manner, the other end of the first electric conductor and the other end of the second electric conductor are respectively connected with two poles of the control panel assembly, the first temperature sensing switch is arranged at a position on the side surface of the shell facing the instant heating pipe, which corresponds to the first electric conductor, and is used for controlling the on/off of the first electric conductor, the second temperature sensing switch is arranged at a position on the side surface of the shell facing the instant heating pipe, which corresponds to the second electric conductor, and is used for controlling the on/off of the second electric conductor, the temperature sensing threshold value of the first temperature sensing switch is lower than that of the second temperature sensing switch. Because one end of the first conductor and one end of the second conductor are respectively connected with two poles of the instant heating type heating pipe in a clinging manner, the other end of the first conductor and the other end of the second conductor are respectively used for connecting two poles of the control panel component and then are connected with the power supply through the control panel component, so that the electric connection between the instant heating type heating pipe and the power supply is realized, and two wires are omitted. Because the first temperature sensing switch and the second temperature sensing switch are directly arranged on one side surface of the shell of the temperature control component, the two temperature sensing switches can omit a plurality of wires. Therefore, the wiring in the instant liquid heater is greatly simplified, and the installation and operation of all parts in the instant liquid heater are convenient. During specific work, the instant heating pipe in the liquid heating module is started and stopped by the control panel component according to the temperature value detected by the temperature sensor on the instant heating pipe, namely when the control panel component is out of order, the first temperature sensing switch and the second temperature sensing switch can not act and are in a standby state. Once the control panel subassembly goes wrong, can not let the instant heating pipe stop when should stopping, instant heating pipe will continue work so, and the temperature will continue to rise, and when the temperature rose to the temperature sensing threshold value of first temperature sensing switch, first temperature sensing switch will act and cut off the route of first electric conductor for instant heating pipe outage avoids taking place danger. If the control panel assembly and the first temperature sensing switch are both in failure, the second temperature sensing switch is arranged, the principle of the second temperature sensing switch is similar to that of the first temperature sensing switch, when the temperature of the heating disc rises to the temperature sensing threshold value of the second temperature sensing switch, the second temperature sensing switch can act to cut off the path of the second electric conductor, so that the heating pipe is powered off, and danger is avoided. Therefore, three safety switches are equivalently arranged for the liquid heating module, and the danger can be basically and completely avoided.

The first temperature sensing switch is automatically resettable, that is, when the temperature rises to the temperature sensing threshold of the first temperature sensing switch, the first temperature sensing switch will operate to disconnect the path of the first conductor, and when the temperature drops below the temperature sensing threshold again, the first temperature sensing switch will automatically reset to reconnect the path of the first conductor. The second temperature sensitive switch is manually resettable, i.e., when the second temperature sensitive switch is actuated to cut off the passage of the second conductor, the second temperature sensitive switch does not automatically reset, and must be manually reset. Therefore, when the first temperature-sensing switch acts, the control panel assembly is indicated to have a problem, only the control panel assembly needs to be maintained, and the first temperature-sensing switch can be automatically reset. When the second temperature-sensing switch acts, the control board assembly and the first temperature-sensing switch are both in a problem, after the control board assembly and the first temperature-sensing switch are repaired, the second temperature-sensing switch is manually reset, but the probability of the problem is extremely low.

Furthermore, the first temperature sensing switch comprises a first connecting column and a self-resetting temperature sensing piece, one end of the first connecting column is fixedly connected with the position, close to the other end of the first conductive elastic piece, and the self-resetting temperature sensing piece is fixed on the side, facing the instant heating pipe, of the shell and is fixedly connected with the other end of the first connecting column. When the temperature is lower than the temperature sensing threshold value of the self-resetting temperature sensing piece, the self-resetting temperature sensing piece is convex towards one side, when the temperature rises to the temperature sensing threshold value of the self-resetting temperature sensing piece, the self-resetting temperature sensing piece can be convex towards the opposite side to deform, and when the temperature is reduced again, the self-resetting temperature sensing piece can automatically reset. In the utility model, when the temperature reaches the temperature sensing threshold value of the self-resetting temperature sensing sheet, the self-resetting temperature sensing sheet can be convexly deformed towards the side back to the instant heating type heating pipe and extrude the first connecting column, and the first conductive elastic sheet is extruded and deformed through the first connecting column, so that the other end of the first conductive elastic sheet is separated from the other end of the first conductive metal sheet; when the temperature is reduced to be lower than the temperature sensing threshold value again, the temperature is deformed and reset towards the side of the instant heating type heating pipe, the first conductive elastic sheet is reset under the action of the elastic force of the first conductive elastic sheet, the other end of the first conductive elastic sheet is contacted with the other end of the first conductive metal sheet again, and then the path of the first conductor is conducted again.

Like this, when the temperature of instant heating pipe rose to the temperature sensing threshold value of second temperature-sensing switch, second temperature-sensing switch will act and push away the electrically conductive shell fragment of second, make the other end of the electrically conductive shell fragment of second and the other end of second conductive metal piece separate, then the route of second electric conductor has just been broken off, because second temperature-sensing switch is the hand resettable, so even when the temperature drops to the temperature sensing threshold value that is less than second temperature-sensing switch, second temperature-sensing switch also can not automatic re-setting, must just reset through manual, and then make the other end of the electrically conductive shell fragment of second and the other end of second conductive metal piece contact once more, then the route of second electric conductor has just switched on again.

As shown in fig. 1 to 5, a liquid heating module comprises an instant heating type heating pipe 1, a temperature control component 2 for controlling on/off of the instant heating type heating pipe 1, a water pump 3 for supplying water to the instant heating type heating pipe 1, and a control board component 4 for controlling the instant heating type heating pipe 1, the temperature control component 2 and the water pump 3, wherein the temperature control component 2 and the water pump 3 are connected with the control board component 4 through wires, the temperature control component 2 is electrically connected with the instant heating pipe 1, wherein, the device also comprises an installation seat 5, one side of the installation seat 5 is provided with a first installation groove 51 and a second installation groove 52 which are adjacent, the other side of the mounting seat 5 is provided with a third mounting groove 53, the instant heating type heating pipe 1, the water pump 3 and the control panel component 4 are respectively fixed in the first mounting groove 51, the second mounting groove 52 and the third mounting groove 53, the temperature control assembly 2 is fixed on the mounting base 5 and is tightly attached to the instant heating type heating pipe 1. Therefore, the instant heating type heating pipe 1, the temperature control assembly 2, the water pump 3 and the control panel assembly 4 are integrated together by only utilizing one mounting seat 5, the positions of all the components are relatively fixed, the structure is very compact, the length of a connecting wire can be shortened, the wiring inside the container is simplified, all the components can be mounted and fixed on the mounting seat 5 in advance, and then the main shell is placed in, so that the mounting operation is simplified.

As shown in fig. 1 to fig. 6, the temperature control assembly 2 includes a first temperature-sensing switch 21 capable of automatically resetting and a second temperature-sensing switch 22 capable of manually resetting, which are capable of separately controlling the on/off of the instant heating pipe 1, and temperature sensing ends of the first temperature-sensing switch 21 and the second temperature-sensing switch 22 are closely attached to the outer wall of the instant heating pipe 1. Thus, the first temperature-sensitive switch 21 and the second temperature-sensitive switch 22 on the instant heating pipe 1 and the temperature-controlled assembly 2 are all integrated on the mounting base 5, so that they become an integrated module, and thus, the assembly is much simpler.

As shown in fig. 6 and 7, the temperature control assembly 2 further includes a housing 23, and a first conductor 24 and a second conductor 25 which are arranged in the housing 23, wherein both ends of the first conductor 24 and the second conductor 25 extend out of the housing 23, one end of the first conductor 24 and one end of the second conductor 25 are respectively connected to two poles of the instant heating pipe 1 in a close contact manner, the other end of the first conductor 24 and the other end of the second conductor 25 are respectively connected to two poles of the control board assembly 4, the first temperature-sensitive switch 21 is arranged at a position corresponding to the first conductor 24 on a side surface of the housing 23 facing the instant heating pipe 1 and is used for controlling on/off of the first conductor 24, and the second temperature-sensitive switch 22 is arranged at a position corresponding to the second conductor 25 on a side surface of the housing 23 facing the instant heating pipe 1 and is used for controlling on/off of the second conductor 25 And the circuit is switched off, and the temperature sensing threshold value of the first temperature sensing switch 21 is lower than that of the second temperature sensing switch 22. Because one end of the first conductor 24 and one end of the second conductor 25 are respectively connected with two poles of the instant heating type heating pipe 1 in a clinging manner, the other end of the first conductor 24 and the other end of the second conductor 25 are respectively used for connecting two poles of the control panel component 4, and then are connected with the power supply through the control panel component 4, the electric connection between the instant heating pipe 1 and the power supply is realized, and two wires are omitted. Since the first temperature-sensitive switch 21 and the second temperature-sensitive switch 22 are directly disposed on one side of the casing 23 of the temperature-controlled assembly 2, the two temperature-sensitive switches can omit several wires. Therefore, the wiring in the instant liquid heater is greatly simplified, and the installation and operation of all parts in the instant liquid heater are convenient. During specific work, the instant heating pipe 1 inside the liquid heating module is started and stopped by the control board assembly 4 according to the temperature value detected by the temperature sensor on the instant heating pipe 1, that is to say, when the control board assembly 4 is out of order, the first temperature sensing switch 21 and the second temperature sensing switch 22 are both not operated and are in a standby state. Once the control board assembly 4 is out of order, the instant heating pipe 1 cannot be stopped when it is stopped, and then the instant heating pipe 1 will continuously work, and the temperature will continuously rise, and when the temperature rises to the temperature sensing threshold value of the first temperature sensing switch 21, the first temperature sensing switch 21 will act to cut off the path of the first conductor 24, so that the instant heating pipe 1 is powered off, and the danger is avoided. If the control panel assembly 4 and the first temperature sensitive switch 21 are both disabled, the second temperature sensitive switch 22 is provided, the principle thereof is similar to that of the first temperature sensitive switch 21, when the temperature of the heating plate rises to the temperature sensitive threshold of the second temperature sensitive switch 22, the second temperature sensitive switch 22 will act to cut off the path of the second conductor 25, so that the heating tube is powered off, and danger is avoided. Therefore, three safety switches are equivalently arranged for the liquid heating module, and the danger can be basically and completely avoided.

In this embodiment, since the first temperature sensitive switch 21 is automatically resettable, that is, when the temperature rises to the temperature sensitive threshold of the first temperature sensitive switch 21, the first temperature sensitive switch 21 operates to disconnect the path of the first conductor 24, and when the temperature drops below the temperature sensitive threshold again, the first temperature sensitive switch 21 automatically resets to reconnect the path of the first conductor 24. The second temperature sensitive switch 22 is manually resettable, that is, when the second temperature sensitive switch 22 is operated to cut off the passage of the second conductor 25, it is not automatically restored, and manual resetting is required. Therefore, when the first temperature sensitive switch 21 is operated, it is indicated that the control panel assembly 4 is in a problem, and the first temperature sensitive switch 21 can be automatically reset only by maintaining the control panel assembly 4. When the second temperature sensitive switch 22 is operated, it means that both the control panel assembly 4 and the first temperature sensitive switch 21 have problems, and after the control panel assembly 4 and the first temperature sensitive switch 21 are repaired, the second temperature sensitive switch 22 is manually reset, but the probability of the situation is very low.

As shown in fig. 6 to 8, the first conductor 24 includes a first conductive metal sheet 241 and a first conductive elastic sheet 242 fixed in the housing 23, one end of the first conductive metal sheet 241 extends to the outside of the housing 23 and is tightly attached to one pole of the instantaneous heating pipe 1, one end of the first conductive elastic sheet 242 extends to the outside of the housing 23 and is connected to one pole of the control board assembly 4, the other end of the first conductive metal sheet 241 and the other end of the first conductive elastic sheet 242 are both disposed in the housing 23 and are tightly attached to each other, the first conductive elastic sheet 242 is in a natural state, and the first temperature-sensitive switch 21 is connected to the first conductive elastic sheet 242 at a position close to the other end thereof. Thus, when the temperature of the instant heating pipe 1 rises to the temperature sensing threshold of the first temperature sensing switch 21, the first temperature sensing switch 21 acts to push the first conductive elastic sheet 242 open, so that the other end of the first conductive elastic sheet 242 is separated from the other end of the first conductive metal sheet 241, the path of the first electric conductor 24 is disconnected, at this time, the first conductive elastic sheet 242 is deformed and is in an energy storage state, when the temperature drops to a temperature sensing threshold lower than the first temperature sensing switch 21, the first temperature sensing switch 21 automatically resets, the first conductive elastic sheet 242 rebounds under the action of its own elastic force, so that the other end of the first conductive elastic sheet 242 and the other end of the first conductive metal sheet 241 are contacted again, and then the path of the first electric conductor 24 is switched on again.

As shown in fig. 6 to 8, the first temperature-sensitive switch 21 includes a first connecting pillar 211 and a self-resettable temperature-sensitive sheet 212, one end of the first connecting pillar 211 is fixedly connected to a position of the first conductive elastic sheet 242 near the other end thereof, and the self-resettable temperature-sensitive sheet 212 is fixed to a side of the housing 23 facing the instantaneous heating pipe 1 and is fixedly connected to the other end of the first connecting pillar 211. The self-resettable thermal sensing strip 212 is convex toward one side at a temperature lower than its temperature sensing threshold, and when the temperature rises to its temperature sensing threshold, it will be convex toward the opposite side and deformed, and when the temperature drops again, it can reset automatically. In the present invention, when the temperature of the self-resettable temperature sensing piece 212 reaches its temperature sensing threshold, it will bulge and deform towards the side facing away from the instant heating pipe 1, and extrude the first connection column 211, and extrude and deform the first conductive elastic piece 242 through the first connection column 211, so that the other end of the first conductive elastic piece 242 is separated from the other end of the first conductive metal piece 241; when the temperature is reduced to be lower than the temperature sensing threshold value again, the temperature will deform and reset towards the side of the instant heating pipe 1, and the first conductive elastic sheet 242 will reset under the action of the elastic force of the first conductive elastic sheet 242, so that the other end of the first conductive elastic sheet 242 and the other end of the first conductive metal sheet 241 are contacted again, and then the path of the first conductor 24 is conducted again.

As shown in fig. 6 to 8, the second conductor 25 includes a second conductive metal sheet 251 and a second conductive elastic sheet 252 fixed in the housing 23, one end of the second conductive metal sheet 251 extends out of the housing 23 and is in close contact with the other pole of the instantaneous heating pipe 1, one end of the second conductive elastic sheet 252 extends out of the housing 23 and is connected with the other pole of the control board assembly 4, the other end of the second conductive metal sheet 251 and the other end of the second conductive elastic sheet 252 are both disposed in the housing 23 and are in close contact with each other, the second conductive elastic sheet 252 is in a natural state, and the second temperature-sensitive switch 22 is connected with the second conductive elastic sheet 252 at a position close to the other end thereof. Thus, when the temperature of the instant heating pipe 1 rises to the temperature sensing threshold of the second temperature sensing switch 22, the second temperature sensing switch 22 will act to push the second conductive elastic sheet 252 open, so that the other end of the second conductive elastic sheet 252 and the other end of the second conductive metal sheet 251 are separated, the path of the second conductor 25 is disconnected, and since the second temperature sensing switch 22 is resettable by hand, even if the temperature drops to a temperature lower than the temperature sensing threshold of the second temperature sensing switch 22, the second temperature sensing switch 22 will not reset automatically, and only needs to reset manually, so that the other end of the second conductive elastic sheet 252 and the other end of the second conductive metal sheet 251 contact again, and the path of the second conductor 25 is switched on again.

As shown in fig. 6 to 8, the second temperature-sensitive switch 22 includes a second connection pillar 221 and a non-self-resettable temperature-sensitive sheet 222, one end of the second connection pillar 221 is fixedly connected to the position of the second conductive elastic sheet 252 close to the other end thereof, and the non-self-resettable temperature-sensitive sheet 222 is fixed to the side of the casing 23 facing the instantaneous heating pipe 1 and is fixedly connected to the other end of the second connection pillar 221. When the temperature is lower than the temperature sensing threshold value, the temperature sensing sheet capable of being reset manually is convex towards one side, when the temperature rises to the temperature sensing threshold value, the temperature sensing sheet capable of being reset manually is convex towards the opposite side to deform, and when the temperature is reduced again, the temperature sensing sheet cannot be reset automatically and needs to be reset manually. In the present invention, when the temperature of the non-resettable temperature sensing piece 222 reaches the temperature sensing threshold value thereof, it will deform toward the side back to the instant heating pipe 1, and extrude the second connection column 221, and extrude the second conductive elastic piece 252 through the second connection column 221, so that the other end of the second conductive elastic piece 252 is separated from the other end of the second conductive metal piece 251; when the temperature is reduced to be lower than the temperature sensing threshold value again, the instant heating pipe 1 is not deformed and reset towards the side, and manual reset is needed, so that the other end of the second conductive elastic sheet 252 is contacted with the other end of the second conductive metal sheet 251 again, and the path of the second conductor 25 is conducted again.
