as shown in fig. 1 to 4, two ends of the flow disturbing pipe 12 are open, a water inlet flow disturbing end cover 121 and a water outlet flow disturbing end cover 122 are respectively provided, a first water passing hole 1211 is provided on the water inlet flow disturbing end cover 121, a second water passing hole 1221 is provided on the water outlet flow disturbing end cover 122, and the first water passing hole 1211, the flow passing gap and the second water passing hole 1221 form a water flow channel.

In this embodiment, the water flow path is: water flows into the heating pipe body 11 from the water inlet at one end of the heating pipe body 11, flows into the through-flow gap through the first water passing hole 1211, flows along the through-flow gap and heats, and then flows out through the second water passing hole 1221 and the water outlet at the other end of the heating pipe body 11.

In some embodiments, the intake spoiler end cap 121 and the outlet spoiler end cap 122 are mounted by clamping with the spoiler tube 12. Specifically, the water inlet turbulence end cover 121 includes an annular first cover 1212 and a first end plug 1213 protruding from the middle of the first cover 1212, the first end plug 1213 extends into the turbulence tube 12 to be in plug-in fit with the turbulence tube 12, the outer diameter of the first cover 1212 is larger than the outer diameter of the turbulence tube 12, and a plurality of first water passing holes 1211 are circumferentially arranged on the end surface of the first cover 1212 outside the turbulence tube 12; the water outlet spoiler end cover 122 comprises an annular second cover body 1222 and a second end plug 1223 protruding in the middle of the second cover body 1222, the second end plug 1223 stretches into the spoiler 12 to be in plug-in fit with the spoiler 12, the outer diameter of the second cover body 1222 is larger than that of the spoiler 12, and a plurality of second water passing holes 1221 are circumferentially arranged on the end surface of the outer side of the spoiler 12 of the second cover body 1222. In the installation, the first end plug 1213 is only required to be plugged into the spoiler 12, the spoiler 12 is abutted against the first cover 1212, the second end plug 1223 is plugged into the spoiler 12, and the spoiler 12 is abutted against the second cover 1222. The provision of the plurality of first water passing holes 1211/second water passing holes 1221 in the circumferential direction may promote the water to flow from the plurality of first water passing holes 1211 into the through-flow gap and to be sufficiently contacted with each region of the inner wall of the heating pipe body 11, and may improve the heating efficiency.

In this embodiment, the water flow path is: the water flows into the overflow gap between the heating pipe body 11 and the turbulent pipe 12 from the water inlet at one end of the heating pipe body 11, flows along the overflow gap and is heated, and then flows out from the water outlet at the other end of the heating pipe body 11.

Preferably, the spoiler tube 12 is a stainless steel structure. Therefore, the plastic end covers can be prevented from being used at the two ends of the turbulence tube 12, so that peculiar smell is generated in the heating process, and the taste of hot water is ensured.

On the basis of the embodiment, the instant heating body of the application is further optimized.

Preferably, the first guide member 15 and the second guide member 16 are silica gel members, so as to enhance the installation effect with the heating tube body 11.

In order to further improve the turbulence effect, the outer wall of the spoiler tube 12 is provided with a plurality of spoiler ribs 124, and the spoiler ribs 124 are staggered along the axial direction.

By arranging the turbulence ribs 124, the turbulence effect can be enhanced, the turbulence ribs 124 are in an active state along with the floating process of the turbulence pipe 12, the contact with water flows at different positions can be increased, after the water flows impact the turbulence ribs 124, the water flows back to the heating pipe body 11, the contact times with the heating pipe body 11 are increased, and the heating efficiency is improved; the turbulence ribs 124 are arranged in an axial staggered manner, so that on one hand, the turbulence ribs can be contacted with water flows in a plurality of directions, and on the other hand, a flow channel can be formed in a region where the turbulence ribs 124 are not arranged, so that water can flow through the overflow gap normally, the water is prevented from flowing slowly or blocking, and the heating time of hot water is ensured to be reliable.

Preferably, the shape of the turbulence ribs 124 is arc-shaped, which can increase the turbulence effect, and can provide buffering to reduce the strength of the forward impact of the water flow so as not to influence the normal flow of the water flow. As shown in fig. 2, when the turbulence pipe 12 is vertically arranged and the lower end of the turbulence pipe 12 is a water inlet end, the shape of the turbulence rib 124 is a convex arc curved upwards, so as to delay the flow velocity of water, and enable the water to fully absorb heat.

It should be noted that the shape of the spoiler 124 is not limited to an arc shape, and may be other shapes, such as a straight shape, a folded shape, a wavy shape, etc.

Preferably, at least part of the spoiler ribs 124 are abutted against the inner wall of the heating pipe body 11, and the heating pipe body 11 conducts heat to the spoiler 12 through the spoiler ribs 124. Therefore, the heating pipe body 11 can conduct heat to the turbulent flow pipe 12 through the turbulent flow ribs 124, so that the heating pipe body 11 and the turbulent flow pipe 12 can both provide heat for water flowing through the overflow gap, and the heating efficiency can be improved.

In addition to the above embodiments, the instant heating element of the present application is further developed. The instant heating body also comprises a temperature control component for controlling the on and off of the heating pipe body 11, and the temperature control component comprises a first temperature control capable of automatically resetting

The switch 200 and the second temperature control switch 210 capable of being reset manually, and the temperature sensing ends of the first temperature control switch 200 and the second temperature control switch 210 are abutted with the outer wall of the heating pipe body 11.

In general, the instant heating body can be detected by the electric control component according to the temperature sensor arranged on the instant heating body

The temperature data of the electric control component (0) controls the operation start and stop of the instant heating body, and the temperature control component can not work under the condition that the electric control component can work normally. However, when the electrical control assembly is abnormal, in order to prevent the instant heating body from continuously heating up to cause danger, the temperature control assembly can provide additional safety measures. When the temperature of the instant heating body rises to the temperature sensing threshold value of the first temperature control switch 200, the first temperature control switch 200 can automatically cut off the related circuits, so that the instant heating body is powered off, and dangers are avoided. Further, if the first temperature control switch 200 fails, the temperature of the heating medium is the same as the temperature of the heating medium

When the temperature rises to the temperature sensing threshold of the second temperature control switch 210, the second temperature control switch 210 can also cut off the phase 5 off circuit, so that the instant heating body is powered off, and the danger is avoided. Preferably, the sense of first temperature controlled switch 200

The temperature threshold is smaller than the temperature threshold of the second temperature control switch 210.

Since the first temperature control switch 200 is automatically resettable, that is, when the temperature rises to the temperature sensing threshold of the first temperature control switch 200, the first temperature control switch 200 can automatically cut off the related circuits, thereby enabling the instant heating

The power is turned off, and when the temperature falls below the temperature sensing threshold of the first temperature control switch 200 again, the first temperature control switch 0 200 can be automatically reset, so that the related circuit is turned on. The second temperature control switch 210 is manually resettable, and once the second temperature control switch 210 cuts off the related circuit, the second temperature control switch cannot be automatically restored, and only needs to be manually reset. For further structure and use principles of first temperature controlled switch 200 and second temperature controlled switch 210, reference is made to the related art, and the present application is not developed in detail herein.

Regarding the arrangement manner of the instant heating body, the instant heating body can be used in a vertical arrangement, in which case the lower end of the heating tube 5 body 11 is a water inlet end and the upper end is a water outlet end.

In order to avoid the generation of peculiar smell as much as possible, each structural member forming the instant heating body can be made of stainless steel, metal and other materials as much as possible, and plastic and silica gel materials are avoided.
