Description

Bathroom exhaust fan automatically turns on control device

Technical field

This utility model provides bathroom exhaust fan to automatically turn on control device, belongs to and automatically controls detection field.

Background technology

Further raising along with living standard, increasing people pays close attention to toilet cleaning, exhaust fan in toilet is primarily to get rid of dampness in toilet, gas with foreign flavor etc., but presently mainly Non-follow control exhaust fan is operated, can not be too high for temperature in toilet, dampness is excessive, self-exhausting process is carried out in the case of abnormal flavour is big, propose a kind of bathroom exhaust fan for this and automatically turn on control device, can be to temperature in toilet, humidity, gas with foreign flavor concentration carries out examinations, and be exhausted fan according to testing result and automatically turn on control, environmental drying in effective holding toilet, proper temperature, ventilate smooth.

Summary of the invention

In view of above-mentioned, this utility model main purpose is to provide bathroom exhaust fan to automatically turn on control device, the most automatically keeps environmental drying, proper temperature, ventilation smoothness in toilet.

nullIn order to achieve the above object，The present utility model adopts the technical scheme that: this device is by single-chip microcomputer、Power module、Gas sensor、Humidity sensor、Temperature sensor、Relay driving module、Relay module、Exhaust fan motor module forms，Wherein power module、Gas sensor module、Humidity sensor、Temperature sensor、Relay driving module is connected with single-chip microcomputer respectively，Relay module respectively with relay driving module、Exhaust fan motor module is connected，Humidity sensor、Gas sensor、Temperature sensor detects the change of indoor environment in real time by single-chip microcomputer，Gas sensor predominantly detects hydrogen sulfide、Methanthiol、The concentration of the gases such as ammonia，Humidity sensor mainly realizes detecting toilet humidity，Temperature sensor mainly realizes temperature detection in toilet，Single-chip microcomputer is in normal operating conditions，Obtain detection data in real time to be analyzed，If temperature sensor、Humidity sensor、Any one detected value of gas sensor exceedes predetermined value，Then Single-chip Controlling relay driving module，Realize relay Guan Bi，Control subsequent exhaust fan motor work，Realize degassing function.

This utility model can avoid the manually opened exhaust fan of user to control, and the whole device of direct basis realizes exhaust fan to the detection case of environment of toilet and automatically turns on, and this device possesses preferable practical value.

Accompanying drawing explanation

Fig. 1 is systematic schematic diagram of the present utility model.This device is made up of single-chip microcomputer (1), power module (2), gas sensor (3), humidity sensor (4), temperature sensor (5), relay driving module (6), relay module (7), exhaust fan motor module (8) this device.

Detailed description of the invention

Below in conjunction with the accompanying drawings the present utility model is further detailed.

Fig. 1 is systematic schematic diagram in this utility model, as it is shown in figure 1, it specifically comprises the following steps that

Step 1 power module (2) is that single-chip microcomputer (1) provides its normal working voltage, gas sensor (3), humidity sensor (4), temperature sensor (5) to work simultaneously, obtains the gas with foreign flavor concentration of environment, warm and humid angle value etc. in toilet in real time.

The information such as the gas with foreign flavor concentration detected, warm and humid angle value are analyzed by step 2 single-chip microcomputer (1) with predetermined value, once find that one of which exceedes predetermined value, then single-chip microcomputer (1) controls follow-up relay driving module (6) and starts working.

Step 3 relay driving module (6) controls relay module (7) Guan Bi, provides the voltage of normal work, electric current for subsequent exhaust fan motor module (8).

Step 4 once foreign flavor indoors gas concentration, warm and humid angle value etc. are below predetermined value, then single-chip microcomputer (1) controls relay driving module (6) work, realize cut-out function, it is achieved the disconnection of relay module (7), cause subsequent exhaust fan motor module (8) to quit work.

Claims

1. bathroom exhaust fan automatically turns on control device, it is structurally characterized in that: this device is by single-chip microcomputer (1), power module (2), gas sensor (3), humidity sensor (4), temperature sensor (5), relay driving module (6), relay module (7), exhaust fan motor module (8) forms, wherein power module (2), gas sensor module (3), humidity sensor (4), temperature sensor (5), relay driving module (6) is connected with single-chip microcomputer (1) respectively, relay module (7) respectively with relay driving module (6), exhaust fan motor module (8) is connected.
