Description of the Invention: [Technical Field] The present invention relates to a brush having a brush body and a bundle of bristles held on a bristle carrier, and a method of manufacturing such a brush. [Prior Art] When the bristles of a brush are not bundled on the brush body, the bristles of the bristles are covered and formed by the plastic material, and are held on the brush body, and the like is manufactured. The problem with the brush is that when the brush body is injection molded, the fluid plastic material passes through the individual filaments of the bristle bundle or is pressed by the high pressure on the edge of the tuft due to the high injection pressure, and the excess plastic material is applied to the brush surface. Can be seen' and causes the brush to be unusable. Different devices and methods have been available to solve this problem. A method is disclosed in the European patent application Ep i 11 478 478 A1, in which a plastic component is first injection molded into the end of a bundle of bristles extending into a nest to form a bristle carrier, and then the bristle carrier is placed on In another type of nest, in another type of nest, the brush body is injection molded, and the bristle carrier is covered and formed into a part of the brush body. The bristle carrier can be ejected with a small ejection pressure to avoid overflow of the ejected material in the bristle bundle region. The problem of this scheme is the same as the problem of the conventional brush in which the bristles are directly gathered in the brush body: due to the rigid connection between the bristle bundle and the brush body, the bristle bundle cannot be adapted to the surface to be cleaned when used, and the system is treated as Dental riding is very unfavorable. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a brush and a method of manufacturing the same that can be adapted to the surface of the brush in an elastic manner, and/or its bristle bundle can be manufactured in a simple manufacturing method. Different brushes. The method of the present invention achieves the object that the tuft of bristles fixes the hard-to-nose bristle carrier, and (iv) and the bristle carrier are provided with an intermediate layer composed of -201216894 parts of additional material. Differently, and if necessary, the pre-formed bristle carrier can be connected to the brush body on the one hand, and the other 20,000 faces are connected to the bristle bundle to change the additional material composition, as long as the additional material component is visually discernible from the outside on the finished brush. , you can make different brushes. Advantageously, the fixed end of the bristle bundle is surrounded by the material of the bristle carrier, and the bristle carrier constitutes a separating layer to separate the intermediate layer and the bristle bundle and the additional material component is in contact with the bristle bundle, which can be properly avoided. The bristle area is excessively shot. The fixed ends of the tufts of bristles are also melted, and the individual filaments of the tufts of bristles are connected to each other. Advantageously, the intermediate layer is made of an elastic material. Therefore, the bristle carrier and the bristle bundle are elastically fixed on the brush body, and in fact are fixed to the brush body like "drifting", and if it is a toothbrush, the brush carrier and the bristle bundle generate a retreat when brushing teeth. Adapt yourself to the condition of your teeth for a more thorough and gentler cleansing. For the bristle bundle, this practice forms an elastic cushion. The moon bridges are connected to each other to support such adaptability. The method is that the bristles are placed between adjacent bundles of bristles, and the bristles are weakened, or the bristles are used to accommodate individual tufts. The thinner the web ((10)(6) or similar material, the thinner the bristle carrier, the higher the elasticity. It can also be set on the brush body with multiple buffing carriers^multiple bristles can be gathered-larger overall bristle field, It is also possible to manufacture the different brushes in a simple manner. The advantageous method is that the intermediate layer is at least the outer periphery of the bristles and/or the periphery of the bristle carrier in the transverse direction.塾 料 料 料 料 料 料 料 料 料 料 料 料 料 料 料 料 料 料 料 料 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 亦可 2012 2012 The sheet-like convex joint can be massaged when brushing teeth. The hair bundle price can be paralleled with the ===:::== section, the layer joint can be imagined, the middle layer and the brush body and the brush carrier For splicing or bonding parts, on the bristle carrier and/or brush body When set, the fulcrum projection k brush element, this element as a fulcrum from the brush body holder or body) supported on the other - on the pivot member element. This design ensures that = clearly positioned at the correct interval to each other. The fulcrum 7C piece can be designed as a tip (spitzzulaufend). When the bristle carrier and the brush body are combined, the free end is trimmed or pressed into the other two elements according to the hardness of the fulcrum member. On the one hand, it is possible to preferably hold the upper and lower components, which is advantageous in the case where the prefabricated components are stored for a few days to cause slight deformation and then connected to each other. On the other hand, a stress is generated, and when the additional material components are injection molded, the brush body and the bristle bundle are pressed toward the mold surface of the injection mold to ensure precise positioning of the components. Alternatively, the free end of the bristle carrier fulcrum element engages in one of the receiving pockets of the brush body and/or the free end of the brush fulcrum element engages in one of the receiving pockets of the bristle carrier. This practice allows, for example, a high angular acceleration to be transmitted between the brush body and the bristle carrier on the brush head of the electric toothbrush. The accommodating holes of the bristles and/or the accommodating holes of the bristles can each have an undercut and the free ends of the fulcrum elements each have a correspondingly light contour. The advantage of this design is that the brush body and the bristle carrier are combined with the extra material composition to be injected into the 201216894 mold and can be jointly introduced into the φ a _ 罝 incident cookware, which is for larger brushes, such as hand brushes , washing brush or broom, very beneficial. The bristle bundles 1 can be made to be joined to the bristle carrier by covering the fixed ends of the melted ends thereof. The bristle carrier is formed by covering and ejecting. However, it is also possible to misload the bundle of bristles into a tuft carrier having a hair accommodating hole. It is conceivable that the tufts can also be mounted on a prefabricated tuft carrier via a lion or welding. In the method of the invention, the invention is characterized in that - an additional material component is placed between the qing and the bristle carrier as a connection system. This design has the advantages of prefabricated brushes. Preferably, the <no hairless carrier" is mutually secreted, and the material composition of the material is placed in the intermediate chamber between the brush body and the bristle carrier. In the case of placing additional material components, usually in the injection molding process, in the heating state, the additional material component fills the intermediate empty chamber, and the brush body and the bristles constitute a __ material fitting connection . This manufacturing method has a great advantage in that not only the brush body but also the bristle carrier can be manufactured in advance on different injection molding machines, and additional material components can be placed on a third injection molding machine. The three injection molding machines can be small and simple in construction, making the associated manufacturing apparatus inexpensive to purchase, and the production cost can be reduced. In addition, different prefabricated brush bodies and bristle carriers can be connected to each other on the third injection molding machine, so that a variety of brush types can be manufactured at a lower cost, such as brush bodies having different colors and contact shapes, and A bristle carrier having a differently designed bristle field can be manufactured. Alternatively, the bristle carrier may be coated with additional material components to be ' then coated with a bristle carrier having additional material composition by other materials to form the brush body. 6 201216894 Another variation of the method of the present invention is that additional material components are applied to the brush body and the bristle carrier is applied to the additional material component. The brush body and the bristle carrier are each joined to additional material components. The connection of the brush body, the bristle carrier and the additional material components can be produced in particular by melting. [Embodiment] In Fig. 1 to Fig. 6, 1 represents a brush as a whole, each of which has a brush body 2 and a bristle bundle 3'. The bristle bundle 3 has a melted retention area 6 at the end of the connection side, and is It is held on a bristle carrier 4. Both the brush body 2 and the bristle bundle 3 are injection molded parts made of a hard material. An intermediate layer 5 is provided between the brush body 2 and the bristle carrier 4, and is made of an additional elastomeric material. Therefore, the bristle carrier 4 is not rigidly connected to the brush body 2, but is nearly "drifting" type, so that the bristle bundle 3 has better flexibility on the brush i used here as a toothbrush, and can adapt to the contour of the tooth. Achieve more thorough and gentler cleaning work. The end of the bristle bundle 3 on the fixed side is surrounded by the material of the bristle carrier 4, so that the bristle carrier 4 constitutes a separating layer, so that the intermediate layer 5 and the bristle bundle 3 are kept apart. The additional material composition of the intermediate layer 5 is thus not in contact with the bristle material or the retention zone 6 of the bundle 3: during the manufacture of the brush, the intermediate layer 5, / 7 material components are not formed excessively during the injection molding. Shoot out. In addition, the brush shown in Fig.-, the intermediate layer 5 and the bristle carrier 4 are placed in the basin-like recess. This causes the elastic material component of the k intermediate layer 5 to surround the edge of the bristle field side, and the side of the brush body 2 is only attached to the brush 1 towel shown in FIG. 2, and the elastic material of the intermediate layer 5 is ° With the edge of the brush _ 4, you can see it on the edge _ 5 201216894 The hair carrier 4 can be more retracted to the side than the brush of Figure 1, and slips relative to the brush body 2, so that the bristle bundle 3 adapts to the teeth and adapts to the surface to be cleaned. The ability is stronger. In the brush 1 shown in Fig. 3, the elastic material of the intermediate layer 5 protrudes from the outside of the bristle carrier 4 at the side, and the free end of the brush body 2 is also protruded therefrom. The intermediate layer $ thus constitutes an additional pad that protects the brush 1 from damage. In the brush 1 shown in Fig. 4, a fulcrum member 7 projecting toward the brush body 2 is provided on the bristle carrier 4, and the bristle carrier 4 is in contact with the brush body 2 with the fulcrum member 7. The design can accurately position the bristle carrier 4 and the brush body 2 when the intermediate layer 5 is injection-molded, and the bristle carrier 4 and the brush body 2 are accurately held to each other. The fulcrum member 7 is designed such that its correction is easily pressed into the material of the brush body 2 to further improve the holding ability. In the brush 1 shown in FIG. 5, the brush body 2 has a plurality of fulcrum elements 7 which are each inserted into the receiving pocket 8 of the bristle carrier 4 at their free ends, so that the brush body 2 and the bristle carrier 4 are likewise mounted on - At a position with a certain interval from each other. In addition, better power transfer is achieved between the m' lake body 2 and the bristle carrier 4 via the fulcrum element 7, which is very important on the oscillating rotary toothbrush head of the electric toothbrush. In the brush 1 shown in FIG. 5, not only the intermediate layer 5 is formed with additional material components, but also the additional functional components are also injection molded with additional material components. In this example, the functional components are designed to be massaged in the bristles (4%). And the recording surface 2 is back - the tongue scraper 9b. The additional functional components are connected to the intermediate layer 5 so that the functional components are eaten in a common injection procedure and are manufactured in a suitably designed squid. The brush 1 of Figure 6 also has additional functional components in the form of a tongue plate % and a mucous membrane protection 9C. The latter is mainly used to prevent oral injury when brushing teeth. In the brush of Fig. 6 , a t-piece 7 is applied to the surface 2, and the brush 4 is contacted with the fulcrum element 7, which is similar to the brush i in FIG. Fig. 8 8 201216894 = The component 7 is disposed on the bristle body 4, and the brush body 2 and the bristles are formed with a certain _ 'for the injection molding pour layer 5. Each of the manufacturing cores of the brush 1 is a lancet bundle 3 - an injection molding machine, and is placed on the injection molding machine by ^ = and then ejecting other materials to form the brush body 2. The sapphire is out of the middle layer.
