Description

Technical Field

[0001] This utility model belongs to the field of fan technology, specifically relating to an electric fan with touch sliding control function. Background Technology

[0002] An electric fan is a household appliance that uses an electric motor to drive the fan blades to rotate in order to accelerate air circulation. Its core functions include cooling and air circulation. Household electric fans are essentially axial fans, meaning that the direction of the airflow is parallel to the axis of rotation of the fan blades. Most fans use "knob speed control" or "button speed control". The former requires manual rotation to position, while the latter only supports 3-5 fixed wind speeds.

[0003] The two speed control methods used by the fan have several drawbacks in daily use. The fan control panel is uneven, which makes it easy for dirt to accumulate and difficult to clean. In addition, the fan has problems such as discontinuous speed switching, large speed fluctuations, and poor user experience. Furthermore, the mechanical parts of the fan are prone to wear and tear after prolonged use, resulting in a shorter lifespan and a poor user experience. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] This utility model provides, for example Figure 1 , Figure 2 and Figure 4 As shown, an electric fan with touch sliding control function includes a control box 1, a fan head 2 disposed at the top of the control box 1, and a pole 3 installed at the bottom of the control box 1. The control box 1 is provided with a control component and a sliding component installed on the front panel of the control box 1.

[0026] The control assembly includes a control board 12 and receiving elements 121 and an MCU microcontroller unit 122 respectively mounted on the top and bottom of the control board 12. Several receiving elements 121 are arranged on the top of the control board 12, and the output terminals of the receiving elements 121 are respectively connected to multiple pins on one side of the MCU microcontroller unit 122. The MCU microcontroller unit 122 processes the electrical signals collected by the receiving elements 121 and transmits them to the drive motor in the fan head 2 through a wiring harness.

[0027] Specifically, when a finger touches the touchpad 11, a capacitance is generated, which is transmitted to the MCU microcontroller unit 122 through the output terminal of the receiving element 121. The MCU microcontroller unit 122 senses and receives the electrical signal, processes it, and transmits the processed electrical signal to the drive motor through the wiring harness, so that the drive motor can rotate at a constant speed.

[0028] Furthermore: When a finger touches the touchpad 11 and slides, the position of the capacitor generated by the finger after connecting with the receiving element 121 changes, and the voltage also changes. The electrical signal of the changed voltage is transmitted to the MCU microcontroller unit 122 for processing and then transmitted to the drive motor. The drive motor receives the processed changed electrical signal and adjusts the motor speed accordingly. The speed adjustment method of the drive motor is CLOCK frequency modulation, and the MCU microcontroller unit 122 is a Flash microcontroller SC92R348, thereby realizing stepless speed regulation.

[0029] In this example: as Figure 2As shown, a number of receiving elements 121 are linearly distributed at equal intervals at the top of the control board 12, and each of the receiving elements 121 is in the shape of a spiral column. The receiving element 121 itself has a compression and reset function. When there is a large gap between the control board 12 and the touch panel 11 during installation, the touch panel 11 and the control board 12 can be connected.

[0030] In this example: as Figure 1 and Figure 3 As shown, the sliding touch assembly includes a touch panel 11, a locking block 111 mounted on the edge of the touch panel 11, and a touch groove 112 opened on the touch panel 11; the touch panel 11 is engaged with the mounting groove on the front panel of the control box 1 through the locking block 111, and the shape of the groove 112 corresponds to the shape of the receiving element 121.

[0031] Specifically, the shape of the touch groove 112 is consistent with the shape of the receiving element 121 arranged on the control board 12, thereby limiting the sliding position. After the touch groove 112 is opened on the touch board 11, the flatness of the front panel of the control box 1 is greatly improved compared with the traditional button and knob control, making it more convenient for users to clean the fan in daily life.

[0032] Furthermore, the back of the touchpad 11 is provided with multiple receiving cavities, and the number of receiving cavities corresponds to the receiving element 121. The receiving cavities cover the output end on the top of the receiving element 121, thereby limiting the extended top end of the receiving element 121 and preventing the receiving element 121 from twisting during the installation of the touchpad 11 and the control board 12.

[0033] Example 2

[0034] In this example: as Figure 5 As shown, several receiving elements 121 are provided on the top of the control board 12, and the output terminals of the several receiving elements 121 are respectively connected to multiple pins on one side of the MCU microcontroller unit 122. The receiving elements 121 can be arranged in a sawtooth pattern on the control board 12. In this way, the receiving elements 121 can be arranged in a sawtooth pattern instead of a spiral columnar elastic arrangement, which can effectively save costs. The touch panel 11 and the control board 12 need to be installed in contact.

[0035] Working principle: First, hold and move the pole three times to place the fan in a suitable position, and connect the external power supply at the same time;

[0036] Secondly, by touching and sliding the touchpad 11 with a finger, the fan can be turned on and off and its speed can be adjusted, and then the drive motor inside the fan head 2 can drive the fan blades to deliver air.

[0037] Finally, when the fan needs cleaning, the cleaning cloth can move back and forth on the control box 1 without obstruction, thereby improving the convenience of the fan.
