Abstract

The utility model discloses an automatic window closing device activated in rainy days. The automatic window closing device comprises a single chip microcomputer and a rain sensor; the rain sensor is mounted on the outer side of a window and is connected with an input end of the single chip microcomputer, an output end of the single chip microcomputer is connected with a direct-current gear motor fixed to the middle of a window frame, a gear which is mounted on an output shaft of the direct-current gear motor is in mesh transmission with a rack mounted at the lower edge of a movable window sash, and a normally open key switch which is mounted on the inner side of the window frame is connected with the single chip microcomputer; and the single chip microcomputer is an MC9S12XS128MAL single chip microcomputer, and the rain sensor is an SSM-002 type rain sensor. The automatic window closing device has the advantages that the automatic window closing device is simple in installation, and the original structure of a window does not need to be changed; and the sensitivity of the automatic window closing device can be adjusted, the automatic window closing device is suitable for different climatic environments, high in reliability and low in energy consumption, and damage to an indoor environment due to rainwater is effectively stopped.

Description

A kind of raining closed the window device automatically

Technical field

The utility model belongs to the intelligentized Furniture field, is specifically related to a kind of raining and closes the window device automatically.

Background technology

In daily life, because people's carelessness, forget through regular meeting before going out and close the window that in rainy season, rainy day, rainwater was easy to drench indoor article in the inlet chamber, destroyed indoor health, made troubles for people's life.The application can be on rainy day, owner not the time, automatically with on the window closed, prevent to have very strong Practical significance in the rainwater inlet chamber.

Summary of the invention

At the deficiency that prior art exists, the purpose of this utility model is, provides a kind of raining to close the window device automatically, can rainy day indoor nobody the time, can the automatic close window family.

In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:

A kind of raining closed the window device automatically, comprise single-chip microcomputer and the Raindrop sensor that is installed in the window outside, Raindrop sensor links to each other with the input of single-chip microcomputer, the output of the single-chip microcomputer DC speed-reducing middle with being fixed on window frame links to each other, be installed in gear and the tooth bar engaged transmission that is installed in the movable sashes lower edge on the DC speed-reducing output shaft, the key switch open in usual that is installed in the window frame inboard links to each other with single-chip microcomputer.

The utility model also has following technical characterstic:

Described single-chip microcomputer adopts the MC9S12XS128MAL single-chip microcomputer.

Described Raindrop sensor adopts SSM-002 type Raindrop sensor.

The utility model is installed simple, does not need to change the structure of original window.Sensitivity is adjustable, is applicable to different climatic environments, and reliability height, and low energy consumption are effectively stopped the destruction of rainwater to indoor environment.

Description of drawings

Fig. 1 is an annexation schematic diagram of the present utility model.

Below in conjunction with drawings and Examples particular content of the present utility model is done explanation in further detail.

The specific embodiment

Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.

Defer to technique scheme, as shown in Figure 1, a kind of raining closed the window device automatically, comprise single-chip microcomputer and the Raindrop sensor that is installed in the window outside, Raindrop sensor links to each other with the input of single-chip microcomputer, the output of the single-chip microcomputer DC speed-reducing middle with being fixed on window frame links to each other, and is installed in gear and the tooth bar engaged transmission that is installed in the movable sashes lower edge on the DC speed-reducing output shaft, and the key switch open in usual that is installed in the window frame inboard links to each other with single-chip microcomputer.

Single-chip microcomputer adopts the MC9S12XS128MAL single-chip microcomputer.The MC9S12XS128MAL single-chip microcomputer is 16 single-chip microcomputers of Freescale company exploitation, abundant instruction system is provided, have stronger numerical operation and logical operation capability, the inside Flash program storage of 128KB, the RAM memory of 12KB, the EEPROM of 4KB, integrated serial communication interface, serial device interfaces on the sheet, functional modules such as USB interface, A/D converter, PWM and CAN, it is the processes sensor signal in real time.

Raindrop sensor adopts SSM-002 type Raindrop sensor, is installed in suitable position, the window outside, guarantees just can receive raindrop when it rained just now, after sensor receives raindrop, issues a signal to single-chip microcomputer.And the sensitivity of Raindrop sensor is adjustable, can select sensitivity according to different climatic environments.

When raindrop were fallen on the Raindrop sensor, Raindrop sensor sent a level signal to single-chip microcomputer, and single-chip microcomputer passes through the work of output PWM ripple control DC speed-reducing, and gear rotates, and drives the tooth bar that is fixed on the window lower edge and moves to the direction of closing the window.When window was run into press button, normally open push button switch was closed, and the level signal that single-chip microcomputer is received changes, and single-chip microcomputer sends signal, and DC speed-reducing is stopped operating.The window release of whole pass.

Claims

1. one kind rains and to close the window device automatically, comprise single-chip microcomputer and the Raindrop sensor that is installed in the window outside, it is characterized in that, Raindrop sensor links to each other with the input of single-chip microcomputer, the output of the single-chip microcomputer DC speed-reducing middle with being fixed on window frame links to each other, be installed in gear and the tooth bar engaged transmission that is installed in the movable sashes lower edge on the DC speed-reducing output shaft, the key switch open in usual that is installed in the window frame inboard links to each other with single-chip microcomputer.

2. as claimed in claim 1 raining closed the window device automatically, it is characterized in that described single-chip microcomputer adopts the MC9S12XS128MAL single-chip microcomputer.
