Detailed Description
The present invention will be described in detail with reference to the following embodiments. The following examples will assist those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. These all belong to the protection scope of the present invention.
Example 1
As shown in fig. 1 and 2, the present embodiment provides a drive mechanism including: a suction chamber 7, an eccentric mass 9 and a motor 10.
The suction chamber 7 has an opening, and the eccentric mass 9 includes a rotation center connected to a rotation shaft of the motor 10 and an eccentric portion drivingly connected to a non-central position of an outer wall of the suction chamber 7. The straight line of the opening direction of the air suction chamber 7 is not coincident with the straight line of the eccentric block 9 and the motor 10, and has an included angle of not 90 degrees. Wherein, the non-central position of the outer wall of the air suction cavity 7 is integrally provided with an eccentric block connecting part, and the eccentric part of the eccentric block 9 is rotatably connected on the eccentric block connecting part. The battery 11 is electrically connected to the motor 10 to supply electric power to the motor.
The utility model discloses a driving principle as follows:
the motor 10 rotates to drive the eccentric block 9 to do rotary motion, the eccentric block connecting part on the outer wall of the air suction cavity 7 converts the rotary motion into reciprocating pushing and stretching motion under the action of the eccentric block 9, the air suction cavity 7 is driven to do compression and stretching actions repeatedly, the volume in the air suction cavity 7 is made to change in a reciprocating mode, and therefore the air suction and expiration effects are generated at the opening of the air suction cavity 7. The point of action of the movement of the eccentric mass 9 is on the side of the suction chamber 7 instead of the central one, plus the motor 10 and the eccentric mass 9 are of inclined design, saving space for the whole product.
Example 2
This embodiment is a further modification of embodiment 1, and the driving structure of embodiment 1 is applied to a massage machine.
In addition to the driving mechanism in embodiment 1, the massage machine of the present embodiment further includes: a suction head 6 and a shell.
The shell is detachably connected with one end of the suction head 6, and the suction cavity 7, the eccentric block 9 and the motor 10 are arranged in the shell. The housing includes: the lower shell 2 and the upper shell 3 are detachably connected, and an inner accommodating space is formed by the lower shell 2 and the upper shell 3; the upper shell 3 is provided with a suction cavity connecting port, the edge of the suction cavity 7 is connected with one end of the suction cavity connecting port, and the other end of the suction cavity connecting port is detachably connected with a suction head 6. A mounting frame 8 is arranged in the shell, and the motor 10 and the battery 11 are fixed on the mounting frame 8, so that the internal structure is more compact.
The surface of the shell is wrapped and connected with a silica gel shell 1, so that the hand feeling of holding is better, and the water in the internal structure is prevented from entering. A switch 5 is arranged between the shell and the silica gel shell 1, and the switch 5 is electrically connected with the motor 10 and used for turning on and off the motor 10.
The suction head 6 is attached to the head of the lower shell 3, on the one hand, by face-to-face contact for sealing and, on the other hand, by snap-fitting of the head of the lower shell 3, as shown in fig. 3. The suction head 6 can have different sizes and can be conveniently disassembled and replaced.
The switch 5 preferably employs an FSR pressure sensor to sense the force exerted by the finger on the FSR pressure sensor, the change in resistance of the FSR being reflected in a change in voltage to control the speed of rotation of the motor. The greater the force applied, the faster the motor speed and thus the frequency of inhalation and exhalation of the cleaner head. The two switches are arranged outside the lower shell 3 and covered by the silica gel sheet 4, and are separated from the silica gel shell 1 to play a role in buffering. The pressure switches are used for starting and closing the motor, and simultaneously, the rotating speed of the motor is adjusted according to different voltages output by pressing force, the number of the pressure switches can be one or two so as to be convenient for operation, and the positions of the pressure switches can be opposite to each other in pairs and can also be arranged at 90 degrees.
