Abstract

The utility model discloses a safety electronic tea making pot. The central of a conductive chassis of a pot body has a concave capacity which has a switch pressing column; the central of an upper housing of the chassis has a convex center protection cover which internally has a transmission column; the lower end of the transmission column is sleeved with a transmission column spring; and the transmission column is connected with a micro switch through a micro pressing arm. The utility model respectively arranges a concave capacity and a central jacket, so as to play a guide function and precisely and conveniently splice the pot body and a pot seat; as the upper opening of the central jacket is small and not larger than 3mm, the utility model can not be electrified by mistakenly bumping or pressing. The utility model also overcomes the unsafe factor of the prior art that when a child or an adult mistakenly presses the exposed pressing switch convex column of the electric kettle or the electronic tea making pot, the electricity supply is switched on, thus the conductive pressing bar at the anode and the cathode of the pot seat that can get an electric shock when a person touches the pot.

Description

The Safty electronic kettle of making tea

Technical field

The utility model relates to a kind of household electrical appliance, especially a kind of Safty electronic kettle of making tea.

Background technology

The make tea structure mostly identical with principle (as depicted in figs. 1 and 2) of kettle of existing electric kettle or electronics, the bottom conductive dish of its kettle body is flat circle, from insulating successively every being provided with positive and negative conducting ring and pressing sheet outside to inside.Be respectively equipped with on its kettle seat and corresponding positive and negative conducting compression bars of kettle body bottom conductive dish and push switch projection, wherein positive and negative conducting compression bars and push switch projection all are exposed to outside the upper surface of kettle seat, during use, the kettle body of filled with water is placed on the kettle seat, the pressing sheet of kettle body bottom conductive dish is pushed the conductive switch projection, positive and negative conducting ring is pushed positive and negative conducting compression bars, makes switch conduction, thus the water in the heating kettle body.Though this structure is convenient, but have shortcoming, when child or adult push electric kettle or electronics because of carelessness and make tea the push switch projection that exposes on the kettle seat of kettle, will connect power supply, make the positive and negative conducting compression bars of kettle seat charged, thereby the toucher is got an electric shock, so prior art have unsafe factor.

Summary of the invention

The purpose of this utility model provides a kind of Safty electronic simple in structure kettle of making tea, and is respectively equipped with cavity and central sheath on kettle body and kettle seat chassis, and is safe and reliable, overcome the above-mentioned shortcoming that prior art exists.

The purpose of this utility model is achieved in that it includes kettle body, conductive chassis and chassis, the middle part of the conductive chassis of described kettle body is provided with cavity, be provided with switch pressing post in the cavity, described chassis is made up of chassis upper casing and chassis lower casing, be provided with the central sheath of projection at the middle part of chassis upper casing, be provided with in the central sheath and take off post, the described lower end suit that the takes off post spring that takes off post, taking off post is connected with microswitch by the fine motion laminating arms.

Described cavity is a cylindrical shape, and described central sheath is conical, and central sheath and chassis upper casing are one.

Tapered mouthful of the concave shaped suitable for reading of described central sheath, its cone angle suitable for reading is 5 °-170 °, taking off post is fastened in the central sheath by the taper reducing.

Tapered mouthful of the concave shaped suitable for reading of described central sheath, its cone angle suitable for reading is 60 °, the small end bore of bell is less than or equal to 3mm.

Described central sheath is that its external diameter of going to the bottom of taper is 10mm, and the upper base external diameter is 8mm, and its cone angle suitable for reading is 60 °, and the lower end bore of bell is 2.8mm, and the upper end bore is 5.4mm.

Because the utility model has adopted said structure, compared with prior art has the following advantages: simple in structure, safe and reliable; On kettle body and kettle seat chassis, be respectively equipped with cavity and central sheath, play guide effect, again because of the suitable for reading of central sheath is a back taper, so can make kettle body and the convenient butt joint accurately of kettle seat; Kettle seat chassis is provided with central sheath, the push switch on the protection base, and central sheath is suitable for reading very little; be less than or equal to 3mm; so can not connect power supply when mistake is bumped or pushed, because of bore on its central sheath is very little, push switch also is not easy to be touched by other object again.
