Therefore, the plastic end cover can be prevented from being used, peculiar smell is prevented from being generated in the heating process, and the taste of hot water is ensured.

The fifth embodiment:

the difference from the fourth embodiment is that a cavity is formed in the spoiler tube 12, and a water inlet hole 125 communicating with the cavity is further formed in the water inlet spoiler end cover 121.

In order to cut off the source of odor generation, the turbulence pipe 12, the water inlet turbulence end cover 121 and the water outlet turbulence end cover 122 can use stainless steel structural members, however, rigid connection is difficult to achieve complete sealing, a condition that a small amount of water enters a cavity of the turbulence pipe 12 from a fit gap between the water inlet turbulence end cover 121 and the turbulence pipe 12 exists, a small amount of water entering the cavity is vaporized after being heated, the internal pressure of the cavity is increased, and in addition, air in the cavity expands with heat and contracts with cold, adverse effects are generated on the turbulence pipe 12 for a long time, and collapse of the turbulence pipe 12 can be caused. This application is through setting up inlet opening 125, and at the in-process of intaking, inside water passes through inlet opening 125 entering cavity, until being full of the cavity, water is full of and is in the state of stewing basically after the cavity, does not influence the second of the turbulent flow pipe 12 other end and crosses the water hole and go out hot water. Therefore, a small amount of water can be prevented from being easily vaporized in the cavity, which is not beneficial to prolonging the service life of the turbulent flow tube 12.

As shown in fig. 3 or 5, in the embodiment where the influent disturbing end cap 121 is provided with the first cap 1212 and the first end plug 1213, the influent hole 125 may be provided on the first end plug 1213. The second end plug 1223 of the outlet spoiler end cap 122 is not provided with openings to close the other end of the spoiler 12.

In addition to the above embodiments, the instant heating body of the present application is further developed. The arrangement of the turbulent structure on the turbulent flow tube 12 is not particularly limited in this application, and any of the following methods may be used, for example.

Embodiment six:

the turbulent flow tube 12 is a threaded tube, that is, threads (which can be integrally formed) are arranged on the outer wall of the turbulent flow tube 12. Through will disturbing flow tube 12 laminating heating pipe body 11's inner wall, water can flow around the screw spiral when flowing along overflowing the clearance, can prolong the flow path of water, increases the area of contact of water and heating pipe body 11 inner wall, improves heating efficiency.

Embodiment seven:

the outer wall of vortex pipe 12 is equipped with vortex muscle 126, vortex muscle 126 with the inner wall butt of heating pipe body 11, heating pipe body 11 passes through vortex muscle 126 to the heat conduction of vortex pipe 12.

In this embodiment, on the one hand, the heating pipe body 11 can conduct heat to the spoiler 12 through the spoiler rib 126, so that both the heating pipe body 11 and the spoiler 12 can supply heat to the water flowing through the flow passing gap, and the heating efficiency can be improved. On the other hand, through setting up vortex muscle 126, when water flows along overflowing the clearance, hydroenergy can increase heating area with the muscle wall contact of vortex muscle 126, and when vortex muscle 126 had certain shape, can promote water to flow along certain route, the extension flow path realizes abundant heating, the increasing thermal efficiency.

Preferably, the turbulator 126 is helical. The contact area between the water and the inner wall of the heating pipe body 11 and the outer wall of the turbulent flow pipe 12 can be increased, the full heating is realized, and the heat efficiency is improved.

Further, in some embodiments, as shown in fig. 6, the spoiler rib 126 is provided in a single line and forms a continuous spiral line.

In other embodiments, as shown in fig. 7, a plurality of turbulence ribs 126 are provided, and each turbulence rib 126 is formed in a spiral shape by a plurality of sections of discontinuous sub turbulence ribs 1261. Fig. 7 shows, for example, four spoiler ribs 126, each spoiler rib 126 extends from one end of the spoiler tube 12 to the other end of the spoiler tube 12 along a spiral shape, each spoiler rib 126 includes a plurality of sub spoiler ribs 1261, and a gap 1262 is formed between two adjacent sub spoiler ribs 1261. In this embodiment, when water flows along the flow passage gap, the water may flow along the spiral flow passage, and may also climb along each notch 1262 to form a serpentine/S-shaped flow, so as to ensure that water in each region in the circumferential direction can fully contact with the inner wall of the heating pipe body 11 and the outer wall of the turbulent flow pipe 12, thereby improving the heating effect.

It can be understood that the shape of the spoiler rib 126 is not limited to a spiral shape, and may be any other shape, so as to meet the requirement that water can smoothly pass through the flow passage gap, for example, the spoiler rib 126 is a vertical rib longitudinally arranged along the spoiler tube 12, and the structure is simple and convenient to process.

In addition to the above embodiments, the instant heating body of the present application is further developed. The instant heating body further comprises a temperature control assembly for controlling the power-on and power-off of the heating pipe body 11, the temperature control assembly comprises a first temperature control switch 200 capable of automatically resetting and a second temperature control switch 210 capable of manually resetting, and the temperature sensing ends of the first temperature control switch 200 and the second temperature control switch 210 are abutted to the outer wall of the heating pipe body 11.

Under the normal condition, the instant heating body can control the working start and stop of the instant heating body through the electric control assembly according to the temperature data detected by the temperature sensor arranged on the instant heating body, and the temperature control assembly can not play a role under the condition that the electric control assembly can normally work. However, when the electronic 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 an additional safety measure. When the temperature of the instant heating body rises to the temperature sensing threshold of the first temperature control switch 200, the first temperature control switch 200 can automatically cut off the relevant circuit, so that the instant heating body is powered off, and the danger is avoided. Further, if the first temperature control switch 200 fails, when the temperature of the instant heating element rises to the temperature sensing threshold of the second temperature control switch 210, the second temperature control switch 210 can also be used to cut off the related circuits, so that the instant heating element is powered off, and the danger is avoided. Preferably, the temperature sensing threshold of the first temperature control switch 200 is smaller than the temperature sensing 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 circuit, thereby powering off the instant heater, and when the temperature drops to below the temperature sensing threshold of the first temperature control switch 200 again, the first temperature control switch 200 can be automatically reset, thereby turning on the related circuit. The second temperature controlled switch 210 is manually resettable, and once the second temperature controlled switch 210 disconnects the associated circuit, it cannot be automatically restored, requiring a manual reset. As to further structure and usage principle of the first and second temperature controlled switches 200 and 210, reference may be made to the related art, and the present application is not expanded in detail herein.

Regarding the arrangement of the instant heating body, in either the first embodiment or the second embodiment, the instant heating body can be vertically arranged for use, in which case, the lower end of the heating pipe 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, all structural components forming the heating body can use stainless steel, metal and other materials as much as possible, and plastic and silica gel materials are avoided.
