Description

A kind of smart windproof cap

technical field

The utility model relates to the field of fluid heaters, in particular to the field of design of windproof caps for gas water heaters.

Background technique

The existing gas water heater windproof cap structure is basically all matched by the windproof baffle and the smoke exhaust pipe, and one end of the windproof baffle is connected on the smoke exhaust pipe through a rotating shaft. When the water heater is working, the thrust generated by the flue gas pushes the windshield away to exhaust the smoke; when the water heater stops working, the windshield falls back under its own gravity to cover the exhaust pipe to prevent the outside wind from entering. However, the shaft connection structure between the windshield and the smoke exhaust pipe mainly has the following defects: 1) After a long time of use, the shaft is corroded or the surface of the guide rod is scaled, so that the windshield cannot fall after the water heater stops working And lose the effect of windproof. 2) When the external pressure is greater than the internal pressure, the exhaust pipe is blocked when the water heater can still work normally, causing the water heater to stop working.

Contents of the invention

Aiming at the defects of the existing technology, the purpose of this utility model is to develop an intelligent windproof cap, which can block or open the exhaust port according to the temperature change to block the wind and exhaust smoke, and overcome the problem that the windproof plate is stuck and cannot slide down.

In order to achieve the above object, the utility model adopts the following technical solutions.

An intelligent windproof cap, comprising: a main body, an upper smoke exhaust pipe and a lower smoke exhaust pipe located at the upper and lower ends of the main body respectively, and a windproof baffle arranged between the upper and lower smoke exhaust pipes, characterized in that the windshield The sheet is connected to the lower smoke exhaust pipe through a temperature-sensitive spring, and the temperature-sensitive spring is arranged in the lower smoke exhaust pipe.

As an improvement, a spring fixing plate is arranged inside the lower exhaust pipe, and the temperature sensing spring is connected to the spring fixing plate.

As an improvement, the upper end of the main body is provided with an upper fixing plate for installing the upper smoke exhaust pipe, and the upper smoke exhaust pipe partially passes through the upper fixing plate and is located in the main body.

As an improvement, a guide rod is provided on the windproof baffle, and the guide rod extends into the upper smoke exhaust pipe.

As an improvement, the temperature-sensing spring is a heat-extensible spring; when the temperature-sensing spring contracts, the windproof baffle covers the lower smoke exhaust pipe; A displacement is maintained between the tubes.

Compared with the prior art, the utility model provides an intelligent windproof cap, which uses a temperature-sensitive spring to connect the windproof baffle with the lower smoke exhaust pipe, so that when the water heater stops working, it will be pulled down automatically as the temperature in the lower smoke exhaust pipe decreases. The windproof baffle blocks the lower exhaust pipe to prevent cold air from entering the water heater and prevent freezing. At the same time, due to the deformation effect of the temperature-sensing spring, there is no negative influence that the windproof baffle is stuck and cannot slide down and loses its effect.

Detailed ways

In order to further illustrate the essence of the utility model, the specific implementation of the utility model is described as follows in conjunction with the accompanying drawings.

As shown in Figure 1, a kind of intelligent windproof cap comprises: main body 1, the upper smoke exhaust pipe 2 and the lower smoke exhaust pipe 3 respectively located at the upper and lower ends of the main body 1, and the windshield arranged between the upper and lower smoke exhaust pipes The sheet 4 is characterized in that the windproof baffle 4 is connected to the lower smoke exhaust pipe 3 through a temperature-sensitive spring 5 , and the temperature-sensitive spring 5 is arranged in the lower smoke exhaust pipe 3 .

Specifically, the lower exhaust pipe 3 is provided with a spring fixing plate 6 , and the temperature sensing spring 5 is connected to the spring fixing plate 6 . The upper end of the main body 1 is provided with an upper fixing plate 7 for installing the upper smoke exhaust pipe 2 , and the upper smoke exhaust pipe 2 partially passes through the upper fixing plate 7 and is located in the main body 1 . Further, in order to control the swaying range of the windproof baffle 4 , a guide rod 8 is provided on the windproof baffle 4 , and the guide rod 8 extends into the upper exhaust pipe 2 .

In this embodiment, the temperature-sensitive spring 5 is preferably a heat-extensible spring. In particular, when the temperature-sensitive spring 5 contracts, the windproof baffle 4 covers the lower smoke exhaust pipe 3, and when the temperature-sensitive spring 5 extends, the windproof baffle 4 maintains a displacement between the upper smoke exhaust pipe 2 and the lower smoke exhaust pipe 3. .

During actual installation, the guide rod is fixed in the middle of the windshield, and the two ends of the heat-extensible spring are respectively fixed on the spring fixing plate and the windshield, and then integrally welded to the lower exhaust pipe; the upper fixing plate and the upper row The pipes are welded together; the two welded parts are then welded to the main body.

The working principle is: when the temperature in the lower smoke exhaust pipe is lower than 10°C, the heat-extensible spring will automatically shrink, and the windproof baffle will be pulled to cover the lower smoke exhaust pipe to prevent external wind from entering the water heater; when the water heater is working, the temperature in the lower smoke exhaust pipe will When it rises rapidly, when it is higher than 10°C, the heat-extensible spring pushes away the windshield to keep it away from the upper and lower smoke exhaust pipes, and completely opens the smoke exhaust channel.

The smart windproof cap provided in this embodiment uses thermally stretchable springs to connect the windproof baffle to the lower exhaust pipe, so that when the water heater stops working, the windproof baffle is automatically pulled down to block the lower exhaust pipe as the temperature in the lower exhaust pipe decreases. The smoke exhaust pipe prevents cold air from entering the water heater from the outside, which plays an antifreeze role, and is not afraid of the windshield being stuck and unable to slide down and lose its effect.

The above specific embodiments have described the essence of the utility model in detail, but the protection scope of the utility model cannot be limited by this. All simple improvements and modifications made according to the essence of the utility model all fall within the protection scope of the patent claims.
