As shown in fig. 1 to 8, the present embodiment provides a quick heating device, which can be used for heating drinking water or water for kitchen use, etc., and is preferably used for heating drinking water in the present embodiment. The quick heating device comprises a first water tank 1, a water pump 2, a quick heating pipe assembly 4, a water outlet head 3 and an adjusting assembly 5, wherein the first water tank 1 can be used for storing normal-temperature drinking water, the water inlet end of the water pump 2 is connected with the first water tank 1, the quick heating pipe assembly 4 is connected with the water outlet end of the water pump 2, a water inlet and a water outlet 31 are formed in the water outlet head 3, the water inlet is connected with a quick heating pipe 42, and a runner port 32 is formed between the water inlet and the water outlet 31.

It can be understood that the quick heating device comprises a housing, and the first water tank 1, the water pump 2, the quick heating pipe assembly 4, the water outlet head 3 and the adjusting assembly 5 can be integrated on the housing.

The water pump 2 can pump the water pump 2 in the first water tank 1 into the rapid heat pipe assembly 4, and can be heated by the rapid heat pipe assembly 4, and the heated water can enter the water outlet head 3 from the water inlet of the water outlet head 3 and flow out from the water outlet 31 after flowing through the flow passage opening 32.

In addition, an adjusting component 5 is disposed on the water outlet head 3, and the adjusting component 5 is used for controlling the opening or closing of the rapid heating pipe component 4 and controlling the opening degree of the flow passage port 32.

When the quick heating device is required to provide boiling water, as shown in fig. 7 and 8, the quick heating pipe assembly 4 can be opened through the adjusting assembly 5, so that the quick heating pipe assembly 4 starts a heating function, the water pump 2 in the first water tank 1 can be pumped into the quick heating pipe assembly 4 through the water pump 2, and meanwhile, the runner port 32 can be closed through the adjusting assembly 5, so that water can stay in the quick heating pipe assembly 4 for a long time, and the heating time of the water can be prolonged. When the water in the rapid heat pipe assembly 4 is heated and boiled, the air pressure in the rapid heat pipe assembly 4 is increased, so that the boiling water flows into the water outlet head 3 and further flows out of the water outlet 31.

When it is required to provide normal temperature water using the instant heating apparatus, as shown in fig. 4 and 5, the instant heating pipe assembly 4 may be closed by the regulating assembly 5 while the runner port 32 is fully opened. At this time, the water pumped into the rapid heating pipe assembly 4 can directly enter the water outlet head 3 without being heated, and then flows out of the water outlet 31 through the flow passage opening 32.

When it is required to provide warm hot water having a certain temperature using the instant pipe 42 device, as shown in fig. 4 and 7, the instant pipe assembly 4 may be opened by the regulating assembly 5 while the runner port 32 is partially opened. At this time, the rapid heat pipe assembly 4 can heat the pumped water, and because the runner port 32 is partially opened, the time length of the water staying in the rapid heat pipe assembly 4 can be reduced compared with the case that the runner port 32 is closed, so that the water can flow out from the water outlet 31 after passing through the runner port 32 before being heated to boiling, and thus warm water with a certain temperature can be obtained.

The flow rate of the water passing through the flow passage opening 32 can be realized by adjusting the opening degree of the flow passage opening 32, so that the stay time of the water in the fast heat pipe assembly 4 can be controlled, and the water with different temperatures can be obtained.

Compared with the prior art, the quick heating device provided by the embodiment of the application can realize the adjustment of the opening degree of the flow passage opening 32 in the water outlet head 3 through the adjusting component 5, so that water with different temperatures can be obtained.

Specifically, as shown in fig. 2, fig. 3, fig. 5, fig. 6 and fig. 8, the adjusting assembly 5 includes a baffle 52 and a resisting block 51, the resisting block 51 is rotatably disposed on the water outlet head 3, the baffle 52 is fixedly connected with the resisting block 51, and the resisting block 51 controls the opening degree between the baffle 52 and the runner opening 32.

When the resisting block 51 is rotated, the resisting block 51 can drive the baffle 52 to rotate synchronously, so that the flow passage opening 32 can be closed or opened through the baffle 52.

Specifically, as shown in fig. 5, when it is necessary to flow out the normal temperature water, the stopper 51 may be rotated so that the baffle 52 is located at a position away from the flow port 32, which may be adjacent to the flow port 32, and the center of rotation of the baffle 52 may be located between this position and the flow port 32. When the baffle 52 is at this position, the flow passage opening 32 is completely opened, and the instant heating pipe assembly 4 is not operated, the water pumped out from the water pump 2 can flow out from the water outlet 31 after passing through the water inlet of the water outlet head 3 and the flow passage opening 32 in sequence, so that normal temperature water can be obtained.

As shown in fig. 6, when warm water with a certain temperature needs to flow out, the stop block 51 may be rotated to rotate the baffle 52 to a certain angle in the direction of the runner port 32, so that the runner port 32 is partially opened, and at the same time, the fast heat pipe assembly 4 may be started to heat the water pumped therein by the fast heat pipe assembly 4, and the heated water may flow out from the water outlet 31 through the partially opened runner port 32 before reaching the boiling temperature, so as to obtain warm water with a certain temperature.

As shown in fig. 8, when boiling water needs to flow out, the stop block 51 can be rotated to make the baffle plate 52 close the channel opening 32, at this time, water entering the water outlet head 3 from the water inlet is blocked by the baffle plate 52 and cannot flow out of the channel opening 32 immediately, so that the water can stay in the fast heat pipe assembly 4 for a long time to ensure that the water can be heated to boiling, the boiling water can raise the air pressure in the fast heat pipe assembly 4, so that the boiling water can be pushed to pass over the baffle plate 52 and can further flow out of the water outlet 31, and thus the boiling water can be obtained.

It can be understood that, in order to rotate the abutting block 51, the abutting block 51 may be provided with a knob 53, and the knob 53 protrudes from the surface of the water outlet head 3.

Specifically, as shown in fig. 5, 6 and 8, a part of the outer wall of the resisting block 51 may be provided with a boss 511; the fast heat pipe assembly 4 includes a first switch 41, and the boss 511 abuts on or separates from a contact of the first switch 41.

When the contact of the first switch 41 is pressed, the fast heat pipe assembly 4 can be enabled to start the heating function, and when the contact of the first switch 41 loses the pressing force, the contact of the first switch 41 automatically resets, and at this time, the fast heat pipe assembly 4 stops heating.

Specifically, as shown in fig. 5, when the normal temperature water needs to flow out, the baffle plate 52 is rotated to a position away from the runner opening 32 by the abutting block 51, at this time, the boss 511 on the abutting block 51 does not contact with the contact of the first switch 41, the fast heat pipe assembly 4 is in a closed state, and the water is not heated, so that the normal temperature water can be obtained.

As shown in fig. 6, when warm water with a certain temperature needs to flow out, the abutting block 51 may be rotated to rotate the boss 511 to a position where the boss 511 can press the contact of the first switch 41, wherein when the abutting block 51 is rotated to a position where the boss 511 can press the contact of the first switch 41, the blocking plate 52 may partially block the flow passage opening 32, so as to partially open the flow passage opening 32. At this time, the water passes through the runner port 32 before being heated to boiling, and further flows out through the water outlet 31.

As shown in fig. 8, when boiling water needs to be discharged, the baffle 52 is rotated to the position closing the flow passage opening 32 by the abutting block 51, at this time, the boss 511 keeps contact with the contact, and the fast heat pipe assembly 4 keeps an open state, so as to heat the water to boiling.

Wherein, the fast heat pipe assembly 4 comprises a fast heat pipe 42, a heating assembly is arranged on the side wall of the fast heat pipe 42, and water can be heated in the fast heat pipe 42.

As a specific implementation manner, as shown in fig. 4 and 7, the quick heating device further includes a second water tank 7, the second water tank 7 is provided with a water inlet, a water outlet and a water return port, the water inlet is connected to the water outlet end of the water pump 2, the water outlet is connected to the quick heating pipe assembly 4, and the water return port is connected to the first water tank 1. Specifically, the water inlet may be connected to the water pump 2 through a water inlet pipe 71, the water outlet may be connected to the rapid heating pipe 42 through a water outlet pipe 72, and the water return port may be connected to the water inlet end of the water tank or the water pump 2 through a water return pipe 73. Of course, the water inlet end of the water pump 2 may also be connected to the first water tank 1 through a pipeline, and the water return port may also be connected to a pipeline between the water pump 2 and the first water tank 1 through a water return pipe 73.

Wherein, the second water tank 7 can buffer a certain amount of water, so as to ensure that the water in the second water tank 7 can be stably input into the fast heat pipe assembly 4 and the water outlet head 3. In addition, a liquid level blocking rib 8 is arranged at a position between the water inlet and the water return opening in the second water tank 7. This liquid level fender muscle 8 can restrict the liquid level of the water of buffering in the second water tank 7, and when the water level was higher than liquid level fender muscle 8, the water of many plays can flow back to first water tank 1 from the return water mouth to the volume that can make the water in the second water tank 7 remains stable.

It should be noted that the top end of the liquid level barrier rib 8 is lower than the runner port 32 and higher than the fast heat pipe assembly 4.

When the water pump 2 and the rapid heating pipe assembly 4 stop working, the top end of the liquid level barrier rib 8 is lower than the runner port 32, so that water can be prevented from flowing out of the water outlet 31 through the runner port 32. Meanwhile, the top end of the liquid level blocking rib 8 is higher than the fast heat pipe assembly 4, so that a certain amount of water in the fast heat pipe assembly 4 can be guaranteed, and the problem of dry burning in the fast heat pipe assembly 4 can be prevented.

In addition, for current fast hot device, generally adopt mechanical structure control to go out water, go out water and do not have the timing function, if forget after the device opens and close, the device can continue to go out water, causes the water waste.

For this reason, in the present embodiment, as shown in fig. 1 to fig. 3, the instant heating device further includes a timing switch 6, and the timing switch 6 is disposed on the water outlet head 3.

When the normal-temperature water needs to flow out, the timing switch 6 can be turned on, so that the device is connected with a power circuit, the water pump 2 works at the moment, the quick heating pipe assembly 4 does not work, and the normal-temperature water can be obtained. When the water outlet time reaches the time set by the timing switch 6, the timing switch 6 disconnects the power circuit, the water pump 2 stops working, and the water outlet is finished.

When warm water or boiling water with a certain temperature needs to flow out, the timing switch 6 can be turned on to enable the device to be connected with a power circuit, and at the moment, the water pump 2 and the quick heating pipe assembly 4 work to obtain warm water or boiling water. When the water outlet time reaches the time set by the timing switch 6, the timing switch 6 disconnects the power circuit, the water pump 2 and the quick heat pipe assembly 4 stop working, and the water outlet is finished.

In a specific embodiment, the timer switch 6 may be an electronic timer for ease of operation and reduced failure rates.

In another specific embodiment, as shown in fig. 9 to 18, the time switch 6 may include a damper chamber 55, a movable rod 54, a spring 57, and a second switch 56; the movable rod 54 is slidably connected to the damper chamber 55 so that one end of the movable rod 54 is brought into contact with or separated from a contact of the second switch 56; the spring 57 is provided in the damper chamber 55, and one end of the spring 57 abuts against the inner wall of the damper chamber 55, and the other end of the spring 57 abuts against the other end of the movable rod 54.
