[0005] Preferably, the trachea and exhaust trachea are both soft tubes or hard tubes.

[0006] Preferably, at least one end of the air pipe and the exhaust air pipe is provided with a threaded connection portion, and the threaded connection portion is connected to the threaded hole on the side wall of the end seat.

[0007] Preferably, the air pipe and the exhaust air pipe are connected to the top position of the internal passage of the end seat.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The structure is simple, and the air pipe and the exhaust air pipe are arranged by using the space of the end seat on the heater. There is no need to change the structure of the heating chamber. Different water heaters can increase or decrease the number of heating chambers as needed. Only the number of heaters and air pipes needs to be increased, and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 for Figure 1 Enlarged structural diagram at point A. DETAILED DESCRIPTION

[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0013] like Figure 1-2 As shown, the utility model provides an instant water heater, comprising: a plurality of heating chambers 1 arranged side by side, adjacent heating chambers 1 are connected by a plurality of connecting short tubes 2, water inlet pipes 3 and water outlet pipes 4 are respectively connected to the heating chambers 1 located at the edges of both sides, a heater 6 is inserted into the upper end of the heating chamber 1, the heater 6 comprises a heating tube and an end seat 8 arranged at the upper end of the heating tube, an internal channel connected to the heating chamber 1 is arranged inside the end seat 8, an air pipe 5 connected to the internal channel is connected between adjacent end seats 8, and the end seat 8 on the heating chamber 1 connected to the water outlet pipe 4 is connected to the water outlet pipe 4 through an exhaust air pipe 9.

[0014] Specifically, the heating chamber 1 can be made of metal material, and the outside can be wrapped with an insulation layer. The connecting short pipes 2 can be arranged in an upper and lower staggered manner in sequence. When in use, cold water enters multiple heating chambers 1 through the water inlet pipe 3, and the flowing water is quickly heated by the heater 6 on each heating chamber 1, and then discharged from the water outlet pipe 4. A lot of steam will be generated in the heating process. The rising steam can enter the internal channel inside the end seat 8 from the air pipe 5 and the exhaust air pipe 9, and the steam and hot water are discharged from the water outlet pipe 4.

[0015] In this embodiment, if Figure 1 As shown, the air pipe 5 and the exhaust air pipe 9 are both hoses or hard pipes, which are convenient and flexible to install. At least one end of the air pipe 5 and the exhaust air pipe 9 is provided with a threaded connection part 7, and the threaded connection part 7 is connected to the threaded hole on the side wall of the end seat 8, which is convenient for disassembly and installation.

[0016] In order to allow the steam to be discharged smoothly, the air pipe 5 and the exhaust air pipe 9 are connected to the top position of the internal channel of the end seat 8.

[0017] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0018] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0019] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
