The inside of shell 1 is cavity structure to the shell 1 is close to one side of fixed plate 2 and is formed with the logical groove that is linked together with its inside, and fixed plate 2 is located the below of logical groove, and the one end that the rubber piece 3 was kept away from to drive plate 6 passes this logical groove and extends to the inside of shell 1. The inner side of the shell 1 is fixedly connected with an air cylinder 16 along the horizontal direction, the output end of the air cylinder 16 is fixedly connected with the tail end of the transmission plate 6, and the air cylinder 16 is used for carrying out telescopic movement with a certain frequency, so that the transmission plate 6 is driven to slide on the fixed plate 2, and the transmission plate 6 drives the connecting plate 8, the brush plate 12 and the brush 13 to move towards the tongue root part to clean tongue fur.
In addition, the end of the transmission plate 6 is fixedly connected with a ball screw 17 along the axial extension direction thereof, the inside of the housing 1 is fixedly connected with a fixed cylinder 18 at the periphery of the ball screw 17, and one end of the fixed cylinder 18 is rotatably connected with an incomplete gear 19. An incomplete gear 19 is rotatably connected to one end of the fixed cylinder 18, and the incomplete gear 19, the ball screw 17, and balls between the incomplete gear 19 and the ball screw 17 constitute a ball screw pair. The incomplete gear 19 is connected with a third gear 20 along both sides of the vertical direction in a meshed mode, a shaft lever 21 is fixedly connected to the center of the third gear 20, one end of the shaft lever 21 is rotatably connected with the inner wall of the shell 1, the other end of the shaft lever 21 extends out of the shell 1 towards the direction of the fixed plate 2, then, a silica gel brush 22 is fixedly connected to the other end of the shaft lever, and the two silica gel brushes 22 are respectively distributed above and below the fixed plate 2. The inner wall of the shell 1 is respectively provided with an arc-shaped groove 24 at the position corresponding to each shaft rod 21, the circle center of the arc-shaped groove 24 is concentric with the shaft rods 21, the circumference surface of each shaft rod 21 is fixedly connected with a sliding block 25, the sliding blocks 25 extend into the arc-shaped grooves 24 and are in sliding connection with the arc-shaped grooves, springs 26 are fixedly connected to the two sides of each sliding block 25, and the tail end of each spring 26 is fixedly connected with the end part of each arc-shaped groove 24. The cylinder 16 drives the ball screw 17 to move in the telescopic process, so that the incomplete gear 19 alternately rotates clockwise or anticlockwise, and the two silica gel brushes 22 rotate positively and negatively at a certain frequency, thereby realizing tooth cleaning.
As a preferred embodiment, the silica gel brush 22 in this embodiment has a shape substantially identical to the distribution track of teeth as shown in fig. 9. Meanwhile, when the silica gel brush 22 rotates positively and reversely at a certain frequency through the shaft rod 21, the swing amplitude of the silica gel brush 22 gradually becomes smaller from the two ends of the silica gel brush 22 to the middle of the silica gel brush 22, that is to say, the swing amplitude of the two ends of the silica gel brush 22 is maximum and the middle is minimum. The silicone brush 22 is designed in a shape that gradually widens from both ends toward the middle, and thus the teeth are cleaned more effectively.
The invention provides an oral cavity cleaning device, when the device is used, a hand-held shell 1 is used for feeding the device into the mouth of a patient, teeth of the patient bite into an upper tooth socket 23 and a lower tooth socket 23 respectively, at the moment, two silica gel brushes 22 are attached to the surfaces of the teeth, two brushes 13 are positioned at one third of the front part of a tongue, meanwhile, the top end of a rubber block 3 can prop against the top wall of the oral cavity of the patient, and the device can stably operate in the oral cavity of the patient.
The cylinder 16 is started to perform telescopic movement with a certain frequency, when the cylinder 16 is shortened, the transmission plate 6 is driven to move towards one side of the rubber block 3, the transmission plate 6 slides on the fixed plate 2 through the first T-shaped sliding block 7, and the transmission plate 6 drives the connecting plate 8, the brush plate 12 and the brush 13 to move towards the tongue root part to clean tongue fur. Meanwhile, in the process that the transmission plate 6 drives the connecting plate 8 to move, as the first gear 10 is meshed with the first rack 5, the first gear 10 can rotate clockwise, the first gear 10 drives the second gear 11 to rotate clockwise, and the meshing of the second gear 11 and the second rack 15 can enable the brush plate 12 and the brushes 13 to move to two sides on the second T-shaped sliding block 9 through the sliding seat 14, namely the total length of the two brushes 13 is increased. Similarly, when the cylinder 16 is extended to drive the transmission plate 6 to move to the side away from the rubber block 3, the total length of the two brushes 13 becomes smaller while moving. Because the tongue shape and the tooth distribution are both half elliptic, namely, the width of the tongue gradually becomes larger when the tongue tip reaches the tongue root. The movement mode can avoid the discomfort of a patient caused by the collision with teeth due to overlong fur cleaning of the brush 13 during telescopic movement, and avoid the poor cleaning effect caused by limited cleaning area due to the overlong brush 13.
Meanwhile, when the cylinder 16 is shortened, the ball screw 17 is driven to move to one side of the rubber block 3, the incomplete gear 19 is driven to rotate clockwise, and when the toothed part of the incomplete gear 19 is meshed with the two third gears 20 in the rotating process of the incomplete gear 19, the two third gears 20 are driven to rotate anticlockwise by a certain angle, and then the two silica gel brushes 22 are driven to rotate anticlockwise by a certain angle through the shaft rod 21. Meanwhile, in the process of anticlockwise rotation of the shaft lever 21, the shaft lever 21 drives the sliding block 25 to slide in the arc-shaped groove 24, so that the spring 26 has elastic potential energy, when the incomplete gear 19 rotates to a toothless part, the incomplete gear 19 does not drive the third gear 20 to rotate any more, and under the action of the spring 26, the shaft lever 21 can be reset, namely the silica gel brush 22 can reversely rotate. Therefore, in the clockwise rotation process of the incomplete gear 19, the two silica gel brushes 22 perform forward and reverse rotation with a certain frequency, so that the function of cleaning teeth is achieved. Similarly, when the cylinder 16 extends, the ball screw 17 is driven to move to the side away from the rubber block 3, and the incomplete gear 19 rotates anticlockwise, so that the two silica gel brushes 22 rotate clockwise and anticlockwise at a certain frequency.
While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: many changes, modifications, substitutions and variations may be made to the embodiments without departing from the spirit and principles of the invention, the scope of which is defined by the claims and their equivalents.
