Abstract

The invention relates to an electric fan, especially a melody-driven electric fan. It takes the melody drive module as the core, and is composed of the melody input sub-module, the melody and electrical signal conversion sub-module, and the electrical signal drive sub-module. It is closer to a controllable natural wind state with melodic characteristics, which can improve human comfort.

Description

Melody driven electric fan

technical field

The invention relates to an electric fan, especially a melody-driven electric fan. the

Background technique

As a mature industrial product, electric fans occupy a place in people's lives. Even though air-conditioning products are becoming more and more popular, electric fans are still valued by people for their advantages such as affordable price, convenient use, reliable performance, and no impact on air quality. Studies have shown that in hot environments, wind speed has a great influence on human comfort. Just as melodic sound can create a good sense of hearing, the wind speed with melodic characteristics can also produce a good sense of touch and create a better sense of comfort. Currently, electric fans on the market have two modes for processing wind speed. One mode is to control in different stages according to the wind speed, and each stage has the same wind speed. Another mode is to keep the wind speed in constant random changes. The advantage of the former is that each wind speed is a fixed value, which is convenient to control. The disadvantage is that the thermal feeling of the human body is inert, and the fixed wind speed reduces the comfort of the human body. The advantage of the latter is that the constantly changing wind speed breaks the inertia of the human body's thermal sensation and improves comfort. The disadvantage is that the change of wind speed is disorderly, and it cannot provide the change of wind speed that matches the comfort of human body. the

Contents of the invention

The objectives of the present invention are: 1. Solve the problem that the same constant wind speed electric fan is not conducive to the comfort of the human body; 2. Solve the problem that the wind speed change of the variable wind speed electric fan is out of order. Provided is a melody-driven electric fan with variable wind speed, orderly changing rules of wind speed, sense of melody, and artificially set changing rules. the

The purpose of the present invention can be achieved through the following measures:

1. Build a melody drive module to convert various suitable melodies into corresponding wind speed changes. This module includes three sub-modules, which are melody input sub-module, melody/electric signal conversion sub-module, and electric signal drive sub-module. the

2. The melody drive module can be built into the fan control board, or it can be independent from the fan body and adopt an external type. the

3. The melody input adopts the international common USB interface or infrared interface, which can directly copy the favorite melody from the computer or the network. the

4. The melody driver module has a sound function. The electric fan provides the music playing of the melody while providing the wind field changing according to the melody. the

The arrangement of the above melody driving module not only solves the problem that the fixed wind speed electric fan is not conducive to the comfort of the human body, but also solves the problem of the disorderly change of the wind speed of the ordinary variable wind speed electric fan. At the same time, using the melody as a carrier, it connects the sense of hearing and touch, which is conducive to the harmonious matching of the sense of hearing and touch, forming the best human comfort. the

Beneficial effects of the present invention:

The invention adopts a brand-new wind speed driving mode of the electric fan, overcomes the defect of the traditional electric fan in terms of comfort, can greatly improve the comfort of the human body, and can be applied in various occasions. the

Detailed ways

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

The core of the present invention is the melody driving module. Referring to example Figure 1, different melodies can be converted into corresponding wind speeds. Referring to Figure 2, a melody drive module can be built outside the electric fan body, and the body plus a drive together constitute a melody-driven electric fan. Referring to Figure 3, the melody drive module is built into the control board of the electric fan body to form an integrated melody-driven electric fan. In Fig. 2 and Fig. 3, (1) is the melody input sub-module, (2) is the melody/electrical signal conversion sub-module, (3) is the electric signal driving sub-module, and the three sub-modules together constitute the melody driving module. the

Claims (1)

1. electric fan that melody is driving; It is a core with the melody driver module; Form by melody input submodule (1), melody and electrical signal conversion submodule (2), electrical signal driven element module (3); Each basic submodule is formed the melody driver module jointly, makes electric fan change law of wind speed and melody match, more near a kind of controlled natural wind state with melody characteristics.
