Abstract

The utility model relates to the field of fluid heaters, and discloses an intelligent windproof cap. The intelligent windproof cap comprises a main body, an upper smoke discharge pipe, a lower smoke discharge pipe and a windproof baffle, wherein the upper smoke discharge pipe is located at the upper end of the main body, the lower smoke discharge pipe is located at the lower end of the main body, and the windproof baffle is placed between the upper smoke discharge pipe and the lower smoke discharge pipe. The windproof baffle is connected with the lower smoke discharge pipe through a temperature sensing spring which is placed inside the lower smoke discharge pipe. A spring fixing plate is arranged inside the lower smoke discharge pipe, and the temperature sensing spring is connected with the spring fixing plate. An upper fixing plate for installing the upper smoke discharge pipe is placed at the upper end of the main body, and part of the upper smoke discharge pipe penetrates through the upper fixing plate and is located inside the main body. A guide rod is placed on the windproof baffle and stretches into the upper smoke discharge pipe. Compared with the prior art, the intelligent windproof cap has the advantages that the problem that an effect is lost because the windproof baffle is clamped and cannot slide does not exist.

Description

A kind of intelligence is prevented blast cap

Technical field

The utility model relates to the fluid heater field, relates in particular to the anti-blast cap design field of gas heater.

Background technology

The anti-cap structure of existing gas heater substantially all is to be matched with smoke exhaust pipe by windproof catch, and an end of windproof catch is connected on the smoke exhaust pipe by rotating shaft.During water heater working, the thrust that flue gas produces is pushed windproof catch open, discharges fume; When water heater quit work, windproof catch fell after rise under the gravity effect of self, covered smoke discharging pipe and prevented that extraneous wind from entering.Yet, mainly there is several drawbacks in the rotating shaft connecting structure of this windproof catch and smoke exhaust pipe: 1) service time is than after long, rotating shaft is corroded or the guide rod surface scale, makes after water heater quits work, and windproof can't be fallen and lose windproof effect.2) after ambient pressure is greater than internal pressure, can also just blocks smoke discharging pipe during operate as normal at water heater, and cause water heater to quit work.

Summary of the invention

At the defective that prior art exists, the purpose of this utility model is to develop the anti-blast cap of a intelligence, blocks or open the exhaust opening smoke evacuation of keeping out the wind according to variations in temperature, overcomes the stuck problem that can not glide of windproof catch.

For reaching above purpose, the utility model adopts following technical scheme.

A kind of intelligence is prevented blast cap, comprise: main body, lay respectively at last smoke exhaust pipe and the down smoke-discharging pipe of main body upper and lower end, be arranged on the windproof catch between the upper and lower smoke exhaust pipe, it is characterized in that, described windproof catch is connected with the down smoke-discharging pipe by temperature sensing spring, and described temperature sensing spring is arranged in the down smoke-discharging pipe.

As with improvement, be provided with spring dead plate in the described down smoke-discharging pipe, described temperature sensing spring is connected with spring dead plate.

As with improvement, be provided with to install the upper mounted plate of smoke exhaust pipe on the described main body, described upward smoke exhaust pipe partly runs through upper mounted plate and is positioned at main body.

As with improvement, described windproof catch is provided with guide rod, and this guide rod extend in the smoke exhaust pipe.

As with improvement, described temperature sensing spring is the thermal stretching spring; When temperature sensing spring shrank, windproof catch covered on the down smoke-discharging pipe, during the temperature sensing spring elongation, kept a displacement between windproof catch and last smoke exhaust pipe and down smoke-discharging pipe.

Compared with prior art, a kind of intelligence that the utility model provides is prevented blast cap, utilize temperature sensing spring that windproof catch is connected with the down smoke-discharging pipe, make when water heater quits work, automatically the windproof catch of leaving behind blocks the down smoke-discharging pipe with temperature reduction in the down smoke-discharging pipe, stop cool ambient air and enter in the water heater, play antifreeze effect.Simultaneously, because the deformation effect of temperature sensing spring, there be not stuck can not the downslide of windproof catch and lose the negative effect of effect.

The specific embodiment

For further setting forth essence of the present utility model, by reference to the accompanying drawings the specific embodiment of the present utility model is described as follows.

As shown in Figure 1, a kind of intelligence is prevented blast cap, comprise: main body 1, lay respectively at last smoke exhaust pipe 2 and the down smoke-discharging pipe 3 of main body 1 upper and lower end, be arranged on the windproof catch 4 between the upper and lower smoke exhaust pipe, it is characterized in that described windproof catch 4 is connected with down smoke-discharging pipe 3 by temperature sensing spring 5, described temperature sensing spring 5 is arranged in the down smoke-discharging pipe 3.

Particularly, be provided with spring dead plate 6 in the described down smoke-discharging pipe 3, described temperature sensing spring 5 is connected with spring dead plate 6.Described main body 1 upper end is provided with to install the upper mounted plate 7 of smoke exhaust pipe 2, and described upward smoke exhaust pipe 2 parts run through upper mounted plate 7 and are positioned at main body 1.Further, for controlling the shaking amplitude of windproof catch 4, also be provided with guide rod 8 on the described windproof catch 4, this guide rod 8 extend in the smoke exhaust pipe 2.

In the present embodiment, described temperature sensing spring 5 is preferably the thermal stretching spring.Especially, when temperature sensing spring 5 shrank, windproof catch 4 covered on down smoke-discharging pipe 3, and during temperature sensing spring 5 elongations, 3 of windproof catch 4 and last smoke exhaust pipe 2 and down smoke-discharging pipes keep a displacement.

During actual installation, described guide rod is fixed in the middle of the windproof catch, and described thermal stretching both ends of the spring is separately fixed on spring dead plate and the windproof catch, and integral solder is on the down smoke-discharging pipe again; Upper mounted plate and last smoke exhaust pipe weld together; Two good parts of welding are being welded on the main body.

Operation principle is: when temperature was lower than 10 ℃ in the smoke exhaust pipe instantly, the thermal stretching spring shrank automatically, spurs windproof catch and covers the down smoke-discharging pipe, prevents that extraneous wind from entering water heater inside; When water heater working, temperature raises rapidly in the down smoke-discharging pipe, and when being higher than 10 ℃, the thermal stretching spring is pushed windproof catch open makes it away from upper and lower smoke exhaust pipe, opens discharge flue fully.

A kind of intelligence that present embodiment provides is prevented blast cap, utilize the thermal stretching spring that windproof catch is connected with the down smoke-discharging pipe, make when water heater quits work, automatically the windproof catch of leaving behind blocks the down smoke-discharging pipe with temperature reduction in the down smoke-discharging pipe, stopping cool ambient air enters in the water heater, play antifreeze effect, and be not afraid of stuck can not the downslide of windproof catch and lose effect.

The above specific embodiment has been described in detail essence of the present utility model, but can not come protection domain of the present utility model is limited with this.In every case according to the essence of the utility model, the simple modifications of doing and modification all drop within this patent claim protection domain.
