Description

Kettle lid with boiling whistle

The utility model belongs to a kind of daily necessities, especially the water siren pot lid that boils.

Along with the utility development of China, the fuel that people's lives are used served as main progressively to liquefied gas, coal gas, electric transition by the past with coal, carbon, faggot.Heat up water when people utilize coal gas, liquefied gas,, stamp out the flames, cause liquefied gas, coal gas to leak, cause waste of fuel, lead to a disaster and have no lack of precedents because overlong time is opened boiling because of water and overflowed.For fuel savings, guarantee personal safety and family's wellbeing, people carry out unremitting research, design for head it off.

A kind of " boiling water pot lid handle hollow screw whistling device " disclosed in No. 89211748.6, Chinese patent.It is made up of the newspaper ring handle and the newspaper ring hollow screw that are installed on the pot lid, when water is opened in the kettle, can report ring automatically.A kind of " water is opened the warning pot lid " disclosed again in Chinese patent 90203183.X number.It is made up of battery, bimetallic strip, insulation ball, upper and lower contact, hummer, cover cap, case, cover at kettle by screw retention, when the water water-in-kettle waters out, steam heat after the boiling makes the bimetallic strip action that is close on the pot lid, promote the insulation ball and make upper and lower contacting cell circuit, hummer sends aural signal, reaches the purpose of warning.Above-mentioned newspaper ring device weak point: the one, processing technology complexity, cost height; The 2nd, accessory is many.

The purpose of this utility model provides a kind of water siren pot lid that boils, and utilizes himself architectural feature to reach water and boils and send the signal that pipes.

The purpose of this utility model can reach by following measure: link water that pot lid, handle post, handle cover the form siren pot lid that boils with screw, it is that 8 millimeters, weak point are 5 millimeters oval air admission hole that pot lid and handle post touching position have length.Handle post sub-air chamber and siren chamber.Also to have length be that 8 millimeters, weak point are 5 millimeters oval-shaped ventholes 5～10 millimeters places in the air chamber outside, and except that this, it is 8 millimeters that siren chamber end face edge has length, and weak point is 1 millimeter arc flute hole.Steam heat flows through air admission hole, passes flute hole, circles round in air chamber, thereafter, sends tweeting sound from the venthole outflow.

The purpose of this utility model can also reach by following measure: boil handle cover, the handle post of siren pot lid of water is to make, and once be stamped to form with insulation, heat proof material.

The utility model compared with prior art has following advantage:

(1) the water siren pot lid that boils is simple in structure, safe in utilization, convenient, reliable, and a handle is dual-purpose.

(2) handle cover, handle post can once be stamped to form, and processing cost is low.

(3) need according to design, can send not piping of echo sound.

(4) this device can be installed on other container that need report to the police.

Be described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a cross-sectional view of the present utility model

Fig. 2 is the utility model handle post K to, H to view

Embodiment 1: Fig. 1 illustrates the position relation between the utility model handle cover (1) handle post (2) pot lid (3).With pot lid (3), handle post (2), the handle cover (1) that screw (5) links, handle cover (1) φ=30 millimeters, thickness is 8 millimeters; Handle post (2) φ=18 millimeters, length is 27 millimeters.It is that 8 millimeters, weak point are 5 millimeters oval air admission hole (6), (6 ') that pot lid (3) and handle post (2) touching position have length.Handle post (2) sub-air chamber (8) and siren chamber (4), length are respectively 15 millimeters and 12 millimeters, and at 10～15 millimeters places, air chamber (8) the one ends outside length being arranged is 8 millimeters, and weak point is 5 millimeters oval-shaped ventholes (6 ").This external siren chamber (4) end face edge, (it is 8 millimeters that 6 ") adjacent has length, and weak point is 1 millimeter arc flute hole (7) with venthole.(6 ") are ventilation mutually for air admission hole (6), flute hole (7) and venthole.

The utility model utilizes that bakelite is heat-resisting, insulation, a punching press of the little characteristics of expansion coefficient are made.When water is boiled in the kettle, steam heat after boiling stream by air admission hole (6), pass flute hole (7), circle round in air chamber (8) lining, then, (6 ") outflow and sending pipes from venthole.

In this example, also can have same size at the opposite side of screw (5), and corresponding mutually air admission hole, flute hole and venthole, there is dividing plate in the central authorities of air chamber.Thermal current passes flute hole by air admission hole, flows out from venthole, also can send song.

Embodiment 2: electric heating bowl cover (3 '), handle post (2), handle cover (1) connect with screw (5).Handle cover (1) φ=20 millimeters, thickness are 5 millimeters.Handle post φ=12 millimeters, length is 15 centimetres.It is that 5 millimeters, weak point are 3 millimeters oval-shaped air admission holes (6), (6 ") that bowl cover (3) and handle post (2) touching position have length.Handle post (2) sub-air chamber (8) and siren chamber (4), length are respectively 7 millimeters and 8 millimeters.At air chamber (8) the one ends outsides 3-7 millimeter length being arranged is that 5 millimeters, weak point are that ((it is that 5 millimeters, weak point are 1 millimeter arc flute hole (7) that 6 ") adjacent has length to 3 millimeters oval-shaped ventholes with venthole for 6 "), this external siren chamber (4) end face edge.Air admission hole (6 '), flute hole (7), venthole (6 ") are interconnected, thermal current by air admission hole (6), pass flute hole (7) and in air chamber (8), circle round, (6 ") are flowed out, and pipe and send from venthole then.
