Flossing machine

Technical field

The utility model relates to the field of dental cleaning equipment, more specifically to a dental flossing machine. technical background

It is well known that most floss holders or floss brushes with floss are now manually operated. If the operation and the angle and angle are not accurately controlled, the floss will be broken, and the gums may be bleeding to cause damage to the gums.

SUMMARY OF THE INVENTION The present invention is to overcome the above drawbacks and to create a flossing machine which is low in cost, simple in structure, easy to replace the floss holder, convenient to carry, and convenient to operate, and can enable people to scientifically clean and use correctly. Floss, to avoid more effective cleaning of the residue in the teeth without hurting the gums.

The utility model achieves the utility model aim by the following technical solutions.

The utility model relates to a flossing machine, which comprises a handle, a floss holder fixing device, a reciprocating mechanism and a driving device. The floss holder fixing device is installed at the front end of the handle, and the driving device is installed in the handle through the reciprocating mechanism and the floss The fixture is driven to connect. Drive unit The reciprocating mechanism can drive the floss holder mounted on the floss holder to reciprocate evenly. The electric automatic driving method eliminates the need for manual operation, is simple and convenient to use, and has uniform force and speed control, thereby avoiding damage to the gums.

The drive unit includes a motor and a power source, the motor and the power source are axially mounted inside the handle, and the motor is mounted at the front end of the power source. The compact structure reduces the size of the flossing machine and is easy to carry. The motor is mounted in a motor casing and is powered by a battery and placed in a battery compartment.

Confirmation The battery compartment is mounted at the rear of the motor casing, and the power source is energized to the motor through the positive metal plate and the negative metal plate and the battery spring connection.

The driving device comprises a driving wheel connected to the central shaft of the motor, a driving rod connected at one end to the floss holder fixing device, and the other end of the driving rod is sleeved on the driving wheel, and the positioning pin and the inclined concave side of the driving wheel are provided. Slot fit. It overcomes the defects of large noise and complicated process in gear transmission. This transmission mode has the advantages of less components, simple structure and low failure problems.

In order to facilitate the replacement of the floss holder, the fixing device comprises at least two sheets attached to one end of the driving rod and a locking knob, and the locking knob is engaged with the external thread of the sheet by the internal thread.

The handle is composed of a front and rear housing, and the front housing is provided with a silicone sheath for easy replacement of power and anti-slip effect. The control switch of the drive unit can also be placed on the front housing for easy operation and ergonomics.

Compared with the prior art, the main advantage of the utility model is that the electric method is used instead of the manual method, the force required for cleaning the teeth is scientifically calculated, the fixed power is given by the motor, and the working force is more uniform, Injury of the gums, while the front and rear movements of the flossing frame are used to clean the teeth, the hand can also be moved up and down slightly to make the cleaning more thorough.

Another feature of the utility model is that the flossing head can be replaced at any time. Even if it is not the same person, the handle of the flossing machine can be used together, and only the flossing head can be replaced, and the sanitary head can be cleaned. And it can be loaded with a variety of standard specifications of the flossing head, the compatibility is very wide, as long as the ordinary non-special flossing head can be clamped. Dental floss heads are available everywhere. It solves the defect that the user needs to purchase a special floss head when purchasing other flossing machines.

The floss holder can be removed from the handle, and the floss holder and the floss holder can be carried separately. Very convenient. DRAWINGS

detailed description

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

As shown in FIG. 1, FIG. 2 and FIG. 3, the motor 4 is powered by a battery No. 7, the battery 10 is placed in the battery compartment 2, the battery compartment 2 is mounted at the tail of the motor casing 1, and the power source passes through the positive metal plate 3. The motor 4 is energized in connection with the negative electrode metal piece 8 and the battery spring 9.

A silicone sheath 13 is coated on the outer surface of the front casing 11. The silicone sheath 13 has a circular protrusion 21, and the inner side of the circular protrusion 21 has a small small cylinder and a small front casing 11. The round holes 26 cooperate. When the finger often presses the circular protrusion 21, the inner circular small column presses down the front end of the positive metal piece 3 to contact the metal casing of the motor 4, and the metal casing of the motor is connected to the positive contact of the motor. The circuit is turned on and the motor 4 starts to work. When the finger is released without pressing the circular projection 21, the metal piece 3 bounces off the motor metal casing, the circuit is broken, and the motor 4 is stopped.

A reciprocating mechanism is located within the front housing 11 and includes a drive wheel 5, a drive rod 6 and a positioning pin 7. The drive wheel 5 is tightly fitted to the central shaft of the motor 4, and the drive rod 6 is overlaid from the outer cover on the drive wheel 5, overlapping it, leaving some clearance. The positioning pin 7 is inserted by the small hole 23 on the side of the drive rod 6 and penetrates into the oblique groove 22 in the middle of the drive wheel 5 to cooperate with it. When the motor 4 rotates, the power drives the driving wheel 5 to make a circular motion, and the force of the circular motion drives the positioning needle 7 to perform a tilted linear cyclic motion. The positioning needle 7 is linearly reciprocated along the linear chute 25 in the same manner as the linear motion of the inclined linear motion. The floss frame 15 reciprocates back and forth, as indicated by the arrows and dashed lines in FIG. This type of transmission replaces the ordinary gear transmission, which overcomes the defects of large noise and complicated process in the gear transmission. This mode of transmission has the advantages of fewer components, simple structure and low failure problems.

As shown in Fig. 5, an "F"-shaped floss holder 15 is inserted into the two sheets 24 in front of the drive rod 6, and a locking knob 14 locks the two front bodies 24 of the drive rod 6 to clamp them. The floss holder 15, the locking knob 14 and the two front bodies 24 of the driving rod respectively have matching slopes and internal and external threads 27, and the installation process is as shown in FIG. Therefore, the floss holder 15 is fixed to the driving rod 6, so that when the driving rod 6 performs a longitudinal linear reciprocating motion, the floss head is moved back and forth. As shown in Fig. 4, the broken line portion is the lower state of the entire moving portion.
