Description

Aromatherapy thermostat with magnifying scale display function

technical field

The utility model relates to the field of small household appliances, in particular to a temperature controller for an electronic aromatherapy stove.

Background technique

With the improvement of people's living standards, people gradually like to use electronic aromatherapy stoves to improve air quality. The aroma produced by incense can purify indoor air, eliminate odors, sterilize and disinfect, and also refresh the mind, assist people to clarify their thoughts, improve work efficiency, soothe tension, relieve stress, and improve symptoms such as insomnia and dizziness. The aroma can also create a romantic atmosphere, make people feel warm, make people feel comfortable, and stimulate people's potential immunity. However, the existing electronic aromatherapy furnace generally adopts the form of setting control buttons on the furnace body for regulation, which causes the trouble of inconvenient operation.

Utility model content

In order to overcome the shortcomings mentioned in the prior art, the present invention provides an aromatherapy thermostat with an enlarged scale display function in the form of a wire control, which has an enlarged scale display function and is convenient to operate.

The technical solution adopted by the utility model to solve the technical problem is as follows: an aromatherapy thermostat with an enlarged scale display function, comprising a casing, on which are installed a control button, a temperature control knob, a thermometer, and a switch. Indicator lights and several timing indicator lights, the switch indicator lights, the timing indicator lights and the thermometer are arranged on the upper surface of the housing, all the timing indicator lights are evenly spaced, the control buttons and the temperature control The knob is arranged on the side wall of the casing, a circuit board and a single-chip microcomputer are installed in the casing, and the control button, temperature control knob, thermometer, switch indicator light and timing indicator light are electrically connected to the circuit board and the single-chip microcomputer , The thermometer is provided with a transparent convex lens, which is convenient for observing the temperature. During operation, lightly press the control button on the side, the switch indicator light will be on, and it will work for a long time. Press the control button again, and the timing indicator light will be on. Each time you press the control button, a timing indicator light will be on, and the timing will increase by one hour, until the power switch is turned off at the 7th time. Toggle the knob to select the appropriate temperature according to the fragrance, and you can know the temperature of the electronic aromatherapy stove at this time from the sensible thermometer.

Further, the switch indicator light adopts red LED light, and the timing indicator light adopts green LED light, which is convenient to identify the working state of the electronic aromatherapy stove.

The beneficial effects of the utility model are as follows: the designed aromatherapy thermostat has a compact structure and a reasonable layout, only one control button is used to perform on-off control and timing control at the same time, and the set on-off indicator light and timing indicator light can help to remind this well. It is also equipped with a thermometer equipped with a magnifying glass to facilitate the understanding of the temperature of the electronic aromatherapy furnace.

Detailed ways

The present utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, an aromatherapy thermostat with an enlarged scale display function includes a shell 1, the shell 1 is in the shape of a shell, and the two ends of the shell 1 are provided with wire guides, A control button 11, a temperature control knob 12, a thermometer 13, a switch indicator light 14 and a number of timing indicator lights 15 are installed on the housing 1. The switch indicator light 14, the timing indicator light 15 and the thermometer 13 is arranged on the upper surface of the casing 1, all the timing indicator lights 15 are evenly arranged at intervals, the switch indicator lights 14 are red LED lights, and all the timing indicator lights 15 are green LED lights, which is convenient for identifying the place of the electronic aromatherapy stove. The control button 11 and the temperature control knob 12 are arranged on the side wall of the casing 1 to facilitate pressing operations. The casing 1 is equipped with a circuit board and a single-chip microcomputer. The control button 11 and the temperature control knob 12 The control knob 12, the thermometer 13, the switch indicator light 14 and the timing indicator light 15 are electrically connected to the circuit board, and the single-chip microcomputer is packaged on the circuit board. The thermometer 13 is provided with a transparent convex lens to facilitate observation of the temperature. The convex lens may be pasted at the opening reserved in the casing 1 . Wherein, the circuit board adopts a PCB board made of FR-4 material, and the circuit board integrates a voltage regulation and temperature regulation circuit module composed of a thyristor, a potentiometer and a capacitor. The circuit principle of the present application is shown in Figure 2. The device is connected to the electronic aromatherapy stove through the wires at both ends of the housing 1. During operation, lightly press the control button on the side, the switch indicator light will be on, and it will work for a long time, and then press the control button, The timing indicator light is on, and each time you press an additional timing indicator light, the timing increases by one hour, until the power switch is turned off at the seventh time; turn the knob to select the appropriate temperature according to the fragrance, and you can know the electronic aromatherapy furnace from the thermometer at this time. It is more convenient to check the temperature. Wherein, an insulating buffer sponge gasket is arranged between the circuit board and the casing 1 to prevent the electronic components from loosening or falling off due to collision of the casing 1 during use.

The above are only preferred embodiments of the present invention, and should not limit the scope of implementation of the present invention, that is, any simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the description of the new model are all It still falls within the scope of this new patent.
