Definitions

  • a toothbrush comprising a handle and a cleaning member, the handle comprising a handheld portion and a brush head portion, the handheld portion being connected with the brush head portion, and the cleaning member being fixedly connected with the brush head portion, wherein the cleaning member comprises a plurality of bristles and a bristle plate, the bristle plate being formed by means of integral melting of the bottom of the plurality of the bristles, and the bristle plate being fixedly connected with the brush head portion.
  • the brush head portion comprises a bottom plate and a raised portion fixed to the periphery of the bottom plate.
  • the bottom plate forms an accommodating space with the raised portion, and the bottom of the bristle plate is placed in the accommodating space and fixedly connected with the bottom plate.
  • the bottom plate and the raised portion form an accommodating space in which the cleaning member is placed, which facilitates the placement and fixation of the entire cleaning member.
  • the thickness of the bristle plate is 0.1-2.0 mm. Since the bristle plate is melted and bonded from the bottom of the bristles, the adhesion force of the bristles is the strongest when the thickness of the bristle plate is 0.1-2.0 mm, and filament breakage is not readily to occur. A bigger thickness will render filament breakage occuring frequently.
  • the brush head portion comprises a bottom plate and a raised portion fixed to the periphery of the bottom plate.
  • the bottom plate forms an accommodating space with the raised portion, and the cleaning member is placed in the accommodating space.
  • the bottom of the bristle plate is bonded to the bottom plate with an adhesive or fixed to the bottom plate by ultrasonic welding.
  • the toothbrush made according to the present invention has a large number of bristles and good bristle softness.
  • the bristle plate and the bristles are integrally implanted into the brush head by melt-bonding the bottom of the bristles to form the bristle plate.
  • the entire process does not require any metal sheet, thus reducing the occurrence of metal contamination. Meanwhile, the toothbrush has better cleanliness while providing effectively preventing gingiva bleeding and gingiva damage.
  • a toothbrush comprising a handle 2 and a cleaning member 1.
  • the handle 2 includes a handheld portion 202 and a brush head portion 201.
  • the handheld portion 202 is connected with the brush head portion 201.
  • the cleaning member 1 is fixedly connected with the brush head portion 201.
  • the cleaning member 1 includes a plurality of bristles 101 and a bristle plate 102.
  • the bristle plate 102 is integrally formed by melting the bottom of the plurality of bristles 101.
  • the bottom of the bristle plate 102 is fixedly connected with the top of the brush head portion 201.
  • the fixed connection method can be direct injection bonding by placing into a mold or adhesive bonding or ultrasonic welding.
  • the density of the bristles 101 on the brush head portion 201 is increased, thereby increasing the direct cleaning area of the bristles 101 and the teeth, which is advantageous for the cleaning of the teeth.
  • the bristles 101 have a diameter of 0.05 to 0.25 mm, which is softer than the diameter of the existing bristles 101, and can be operated in a narrow portion such as a tooth neck or an interdental portion. A good brushing performance in the flat portion of the tooth and good effect of removing the whole tooth tartar can thus be provided. Meanwhile, users will feel comfortable when cleaning their teeth, and hence the toothbrush is more conducive to the use of children, pregnant women and those with bleeding gingiva. The effect is particularly good when the diameter of the bristles 101 is 0.07 mm. That is, under the premise of effectively preventing gingiva bleeding and gingiva damage, the toothbrush made from the bristles 101 having a diameter of 0.07 mm has the greatest degree of cleaning of the teeth and the highest rate of dental plaque removal.
  • a neck 2014 may be provided in the middle of the raised portion 2012.
  • the peripheral edge of the bristle plate 102 can be engaged with the neck 2014.
  • the bottom of the bristle plate 102 is fixedly connected to the bottom plate 2011.
  • the neck 2014 is provided in the middle of the raised portion 2012. After the peripheral edge of the bristle plate 102 is fitted to the neck 2014, the entire cleaning member 1 will not bliable to be detached. Then the bottom of the bristle plate 102 is fixedly connected to the bottom plate 2011, which can further enhance the fixing strength between the cleaning member 1 and the brush head portion 201 and prevent the cleaning member 1 from detachment to shorten the life of the toothbrush.
  • the entire side surface of the bristles 101 can be formed into a V-shaped structure.
  • a plurality of bristles 101 having a diameter of 0.05-0.25 mm are placed vertically in a metal mold and heated to 230-500 °C.
  • the bottom of the bristles 101 is integrally melted into a bristle plate 102 in the metal mold.
  • the thickness of the bristle plate 102 is 0.1-2.0 mm.
  • the bristles 101 and the bristle plate 102 integrally form a cleaning member 1. Since the bristle plate 102 is melt-bonded with the bottom of the bristles 101, the bonding force of the bristles 101 is strong when the heating temperature is 400 ° C, and filament breakage is less likely to occur. A lower or higher temperature will cause a more obvious filament breakage or detachment.
  • the brush head portion 201 includes a bottom plate 2011 and a raised portion 2012.
  • a neck 2014 is provided in the middle of the raised portion 2012.
  • the peripheral edge of the bristle plate 102 is embedded in the neck 2014.
  • the bottom of the bristle plate 102 is injection molded and bonded to the bottom plate 2011.
  • the plurality of bristles 101 is closely arranged and the bottom thereof is integrally melted into the bristle plate 102 and the unmelted portions are erected on the bristle plate 102, thus the overall adhesion of the bristles 101 is enhanced. Even if the bristles 101 are small in diameter, it is not readily to suffer from bristle detachment. Meanwhile, the number of bristles 101 is increased on a brush head of the same size, thereby increasing the direct cleaning area of the bristles 101 and the teeth, which is beneficial to the cleaning of the teeth.
  • Test method 10 subjects brush their teeth with various toothbrushes for 3 minutes, and then the comfortable sensation of the toothbrushes is evaluated by their sensory.
