Description

Self-flow heating thermos bottle

The utility model relates to a kind of gravity flow electric heat insulating pot, and particularly its can A.T.C, the gravity flow water outlet.

The gravity flow electric heat insulating pot of Xiao Shouing is the mode of adopt being inverted glass liner in the market, utilizes the deadweight of water and the water outlet of flowing automatically.The water filling of this electric heat insulating pot use inconvenience, and heat-insulating property is not good than imitating difficulty, and water does not burn just outage of boiling.In addition, a kind of electric-heating thermos of stainless steel courage is arranged, this electric-heating thermos heat-insulating property is poor, and power consumption is big, and water can seethe with excitement repeatedly.

The purpose of this utility model will provide a kind of good heat insulating exactly, gravity flow electric heat insulating pot simple in structure.This electric heat insulating pot boils water and rises back outage automatically, heats up automatically, and avoids seething with excitement repeatedly, the gravity flow water outlet.

Solution of the present utility model is: traditional glass liner of thermos that has only a mouth is changed into the upper and lower glass liner of thermos that a mouth is respectively arranged.Be contained in the height (10-12 centimetre) of an about teacup at the bottom of bottle with this glass liner of thermos.Opening part in the glass liner of thermos bottom connects a heating tube, an outlet pipe and a temperature controller, and sealing, heat insulation.The opening part on glass liner top seals with a bottle stopper, and an air inlet pipe and a blast pipe are housed in the bottle stopper.Respectively adorn the bead that a pottery or silicon rubber are made in two pipes, play check valve, during inlet and outlet, air pressure jack-up bead, valve opens, and gas is passed through.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the longitudinal sectional view of a kind of concrete structure of the utility model.

Fig. 2 is the bottle stopper transverse sectional view.

Fig. 3 is circuit theory diagrams.

Referring to accompanying drawing 1: the glass liner of thermos of upper and lower opening (8) is placed on the base (2), is lined with rubber washer (6) between them.Pressing plate (24) is stainless steel or aluminium alloy plate, in order to compress silicone rubber O-ring (23).Pressing plate (24) upper punch has two holes, and each eyelet welding connects or rivet two metal tubes in order to connection outlet pipe (21) and heating tube (22), and seals with silicone rubber sleeve.Temperature controller (21) is close to pressing plate (24) and is connected.Thermal insulation board (25) is made for expansion type plastics or other heat-barrier material.Outlet pipe (20) exceeds 0.4-0.5 centimetre of heating tube (22), keeps a certain amount of water in the glass liner so that make, and prevents the empty burning of heating tube (22).Be lined with rubber washer (11) between bucket (12) and the glass liner of thermos (8).Thread connection between bucket (12) and the ladle body (9).Four taut wires (10) are used to strain ladle body (10) and base (2), and compress glass liner (8).Have passage on the bottle cap (15) and be parallel with balancing weight (16) and spring (17).When covering bottle cap (15), the weight of bottle cap (15) and balancing weight (16) compresses bottle stopper by spring (17), to prevent steam bottle stopper (14) is backed down.Water pipe (7) is a glass tube, is connected with outlet pipe (20) by silicon rubber three-way connection (3), in order to water level in the display bottle.

Referring to Fig. 1 and Fig. 2: an air inlet pipe and a blast pipe are housed in bottle stopper (14).In air inlet pipe, put a bead (29).When discharging water, the pressure in the glass liner (8) is lower than external pressure, and extraneous gas enters bead (29) in the glass liner (8) by air inlet pipe.When heating and water boil when rising, the pressure in the glass liner is higher than external pressure, gas jack-up bead (28) in the glass liner, and discharge by blast pipe.

Referring to Fig. 3 and Fig. 1: when injecting unboiled water in the bottle, plug in, neon lamp (30) is lighted, and shows " power supply ".Switch (31), relay (27) adhesive, temperature controller (18) is connected, and neon lamp (34) is lighted demonstration and " is boiled ".When water boils when rising, the outage of being heated of the steam heating temperature control device (18) in the glass liner (8), temperature controller (18), relay (27) dead electricity resets, temperature controller (21) is connected, but because temperature controller (21) is 90 ℃ for the highest limit temperature, therefore just disconnects before the water boiling.Therefore heating tube (22) is in off-position.Neon (38) obtains electricity and lights demonstration " insulation ".When water temperature drops to 75 ℃ of left and right sides, temperature controller (21) the connection power supply that resets, heating tube (22) heating, neon (35) obtains electricity and lights demonstration " intensification ".When water temperature is raised to 90 ℃, before the boiling, temperature controller (21) does not cut off the power supply again.Like this, both can guarantee that unboiled water can boil, and simultaneously, can avoid water to seethe with excitement repeatedly again.Overtemperature protector (33) is the disposable fuse of 109 ℃ of fusing.Resistance (32.36.37) is the dropping resistor of 100K Ω.

All the other: base cover plate (1), outlet valve (4) water outlet connect turns round (5), bottle stopper packing ring (13), handle (19), supply socket (26).

Claims (3)

1, a kind of glass liner of thermos (8) by upper and lower opening, outlet pipe (20), heating tube (22), bottle stopper (14), ladle body (9), the gravity flow electric heat insulating pot that base (2) is formed is characterized in that glass liner of thermos (8) lower openings place connects heating tube (22) and outlet pipe (20), and upper opening is plugged with bottle stopper (14).

2, according to the gravity flow electric heat insulating pot of claim 1, it is characterized in that air inlet and exhaust piper is housed in the bottle stopper, respectively put a bead in the pipe.

3, according to the gravity flow electric heat insulating pot of claim 1, it is characterized in that temperature controller (18), temperature controller (21) is controlled boiling and the highest intensification respectively.
