Abstract
Prevent two lang leg seats that rise up relates to the seat field. The seat comprises a seat body, a pressure sensor, an MCU controller and an alarm; the pressure sensor and the alarm are respectively connected with the MCU controller; the pressure sensors are arranged at the positions, corresponding to thighs, of the front end of the seat body, and are used for detecting the pressure of a human body after the human body is seated and transmitting the pressure value to the MCU controller; the MCU controller is used for judging whether the human body is in a seesaw-type leg state or not according to the pressure data difference of the two groups of pressure sensors and controlling the on-off of the alarm. The sitting posture reminding device can effectively remind the user of incorrect sitting posture and promote the user to form good sitting posture habit.
Description
Technical Field
The utility model relates to a seat field especially relates to prevent rising up two man leg seat.
Background
Many people sit on the chair and will habitually raise the legs of the two-man body to feel comfortable, but the legs of the two-man body tend to bend over and hump back when sitting, which causes uneven pressure distribution of the lumbar vertebra and the thoracic vertebra, and in the past, the nerves of the spine must be pressed to cause lower back pain. The leg of the Tiger-Er Lang can also obstruct the blood circulation of the leg, causing varicose veins of the leg, and the serious patients often have unsmooth venous return of the leg, sudden bruise, ulcer, phlebitis, bleeding and other diseases.

An object of the utility model is to solve the above-mentioned problem among the prior art, provide and prevent rising up the leg seat of two langs, can effectively remind the incorrect position of sitting of user, make the user form good position of sitting custom.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the anti-lifting leg-leg chair comprises a chair body, a pressure sensor, an MCU (microprogrammed control unit) controller and an alarm; the pressure sensor and the alarm are respectively connected with the MCU controller; the pressure sensors are arranged at the positions, corresponding to thighs, of the front end of the seat body, and are used for detecting the pressure of a human body after the human body is seated and transmitting the pressure value to the MCU controller; the MCU controller is used for judging whether the human body is in a seesaw-type leg state or not according to the pressure data difference of the two groups of pressure sensors and controlling the on-off of the alarm.
The utility model discloses still include the inductor, the MCU controller is connected to the inductor, and the inductor is installed in the rear side or the both sides of seat body, and the inductor is used for responding to whether the human body takes a seat and transmits sensing information to the MCU controller to make the MCU controller open pressure sensor work through the state of taking a seat.
The sensor adopts an infrared sensor or an ultrasonic sensor.
The alarm comprises a buzzer, the buzzer is connected with the MCU controller, and the buzzer is used for giving out sound and electricity alarm.
The alarm comprises a vibrator, the vibrator is connected with the MCU controller, the vibrator is installed at the bottom of the seat body, and the vibrator is used for giving out vibration alarm.
The vibrator adopts an electric motor.
Compared with the prior art, the utility model discloses technical scheme obtains beneficial effect is:
when the user sits on the seat, the infrared sensor senses the human body and sits, the sensing information is transmitted to the MCU controller, the MCU controller controls the pressure sensors to start working, when two groups of pressure sensors sense the pressure of two thighs, the correct sitting posture state is achieved, no alarm can be given, when the user lifts the legs of the Erlang, only one group of pressure sensors senses the pressure of the thighs, the MCU controller controls the buzzer to give out a photoelectric alarm according to the pressure sensing information, the vibrator is controlled to give out a vibration alarm, the user is reminded of the correct sitting posture, when the user puts down the legs, the alarm stops giving an alarm, after the user is used for a period of time, the user can develop the correct sitting posture.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Reference numerals: the seat comprises a seat body 1, a pressure sensor 2, an MCU controller 3, an infrared sensor 4, a buzzer 5 and a vibrator 6.
Detailed Description
In order to make the technical problem, technical solution and beneficial effects to be solved by the present invention clearer and more obvious, the following description is made in detail with reference to the accompanying drawings and embodiments.
As shown in fig. 1, the present embodiment includes a seat body 1, a pressure sensor 2, an MCU controller 3, an alarm, an infrared sensor 4;
the pressure sensor 2, the alarm and the infrared sensor 4 are respectively connected with the MCU controller 3; the infrared sensor 4 is arranged on the rear side of the seat body 1, and the infrared sensor 4 is used for sensing whether a human body is seated or not and transmitting sensing information to the MCU controller 3, so that the MCU controller 3 starts the pressure sensor 2 to work through a seated state;
the two groups of pressure sensors 2 are arranged at the positions, corresponding to thighs, of the front end of the seat body 1, and the pressure sensors 2 are used for detecting the pressure of a human body after the human body is seated and transmitting the pressure value to the MCU controller 3;
the MCU controller 3 is installed at the rear side of the seat body 1 and used for judging whether the human body is in a seesaw-type leg state or not according to the pressure data difference of the two groups of pressure sensors 2 and controlling the opening and closing of the alarm.
Specifically, the alarm includes bee calling organ 5 and electromagnetic shaker 6, MCU controller 3 is all connected to bee calling organ 5 and electromagnetic shaker 6, and bee calling organ 5 is installed in the rear side of seat body 1, and bee calling organ 5 is used for sounding the sound electric alarm, and electromagnetic shaker 6 is installed in the bottom of seat body 1, and electromagnetic shaker 6 is used for sounding the vibration alarm. In this embodiment, the vibrator 6 is an electric motor.
Fig. 1 shows a seat without armrests, and a seat with armrests may be used, and the form of the seat is not limited. In this embodiment, the mounting groove has been seted up to the rear side back department of seat body 1, bee calling organ 5, infrared inductor 4 and MCU controller 3 are all installed in this mounting groove, and MCU controller 3 also can be installed in the bottom of seat body 1.
The working principle of the utility model is as follows:
when the user sits on the seat, infrared inductor 4 senses the human body and sits, sensing information is transmitted to MCU controller 3, MCU controller 3 controls pressure sensor 2 to start working, when two sets of pressure sensor 2 all feel the pressure of two thighs, for correct position of sitting state, can not give out an alarm, when the user lifts up the leg of two langs, only a set of pressure sensor 2 feels the pressure of thigh, MCU controller 3 is according to pressure sensing information, control buzzer 5 sends out the photoelectricity alarm, control electromagnetic shaker 6 sends out vibrations alarm, remind the user to pay attention to correct position of sitting from this, when the user puts down the leg, the alarm stops the alarm, after using a period, the user will develop correct position of sitting habit.
