Description

Brush head structure with elastic soft base and distributed bristles

Technical Field

The invention belongs to the field of cleaning tools, and particularly relates to a brush head structure of a cleaning tool brush.

Background

At present, common brush application scenes in daily life mainly comprise a toothbrush for cleaning teeth, a shoe brush for cleaning shoes and brushes for cleaning the surfaces of clothes or objects, the structures of the brushes with different purposes are basically the same, namely, a handle is held, the front part of the brush is a brush head fully implanted with bristles, a plurality of holes are uniformly distributed on the base of the brush head, a plurality of bristles are implanted into each hole to form a cluster of bristles, the brush head is formed by combining the clusters, the brush has a great defect in use, namely, if the cleaned surface is uneven, the brush is used for brushing and wiping, the structure is limited to the brush head, the bristles are implanted on a hard base, the lengths of the bristles are the same, the concave part of the surface is difficult to clean due to the structure, the smaller concave area and the deeper brush is difficult to clean, and if the concave part is desired to clean, only the force for pressing the brush head is increased, the bristles in contact with the high points of the cleaning surface are forced to bend, and the bristles in the concave part can be contacted with and cleaned in the concave part, so that the service life of the brush is shortened rapidly, on the other hand, if the surface of a brushed object is fine or soft, the surface of the object can be brushed or damaged easily, for example, the tooth can be cleaned by using a toothbrush, the tooth can be brushed vigorously, on the one hand, the gum can be brushed easily, on the other hand, enamel on the surface of the tooth can be damaged easily, if the force is not increased, some deeper tooth gaps can be cleaned difficultly, and especially, the cleaning effect is poorer under the condition that some teeth are uneven.

Disclosure of Invention

The invention provides a brush head structure with elastic soft base distributed implanted bristles, which can ensure that when the brush is used for cleaning the surface of an uneven object, the bristles can penetrate into a concave part without applying excessive pressure on the brush head to bend part of the bristles, thereby achieving ideal cleaning effect, and especially achieving the effect of cleaning the uneven surface on the premise of reducing or not damaging the surface of the fine and easily damaged object.

The brush head structure of the invention is composed of three parts, namely hard base material, elastic soft base material and bristles.

The hard base material forms a bearing support surface of the brush head, the elastic soft base is connected and fixed in the hard base material, the elastic soft base is an elastic material which contracts when being pressed and recovers after the pressure disappears, the elastic soft base has a certain thickness, the bristles are scattered and implanted on the elastic soft base by taking roots as units, and the depth of the bristles implanted in the elastic soft base is shallower under the premise that the bristles are not dropped when in use, so that the better the elastic deformation stroke distance of the elastic soft base is when the bristles are stressed.

Compared with the prior art, the brush head structure provided by the invention has the following gain effects:

in the structure of the existing brush, bristles are planted on a brush head substrate in a mode of a plurality of tufts, the substrate material is a hard non-deformable material, the heights of the bristles are consistent, when part of the bristles are in contact with high points of a cleaned surface when cleaning the surface of an uneven object, the rest bristles cannot be in contact with the surface of the cleaned object, and when other bristles are also in contact with the surface of the cleaned object, pressure is applied to the brush head to bend the bristles which are in contact with the surface of the object first, so that other bristles can be in contact with the surface of the cleaned object, the difference between the high points and the low points of the cleaned surface is more, the pressure applied by the brush head is larger, the deeper the recess of the cleaned surface is, the smaller the area is, and the cleaning effect is poorer; taking tooth brushing as an example, gaps between teeth are always relatively difficult to clean, especially the gaps between teeth close to gingiva are difficult to clean, for cleaning the gaps between teeth, the existing toothbrush can only press the toothbrush head with increased force to brush, so that the brush can easily brush gingiva, even if the teeth are harder, enamel on the surface of the teeth can be easily brushed by forcefully brushing, and the method of increasing the force of the pressing brush head is only effective for the situation that some teeth are arranged more regularly and tightly and the gingiva is plump, and the method of strongly pressing the brush head with the existing toothbrush with a hard base has poor cleaning effect, so-called smoke stain teeth and tea stain teeth of some people can be frequently seen in daily life because of poor tooth regularity, and the like, The gum atrophy is serious, the teeth gaps are deep, the parts are difficult to be effectively cleaned by brushing teeth with the toothbrush with the existing configuration, and smoke spots and tea spots are accumulated day by day.

When the brush adopting the configuration of the invention is used for cleaning the uneven surface of an object, part of bristles firstly contact high points on the surface of the object, and under the action of pressure, the bristles firstly contact the surface of the object and transfer the pressure downwards to the elastic soft substrate, because the bristles in the configuration of the invention are dispersed and implanted in the elastic soft substrate by taking the root as a unit, the bristles under pressure only transfer the pressure to the elastic soft substrate at the root of the bristles, only the elastic soft substrate at the root of the bristles is pressed, contracted and deformed to drive the bristles to move downwards, and the bristles which are not pressed at other parts keep the original shape, and along with the deformation and contraction of the elastic soft substrate at the root of the bristles under pressure, the bristles under pressure drive the part of bristles to move downwards, more bristles contact second high points on the surface of the object, and the bristles contacting the second high points on the surface of the object transfer the pressure to the elastic soft substrate at the root of the bristles under pressure in turn, the soft basement of elasticity is compressed in proper order and is contracted deformation, drive the brush hair downstream, until all brush hairs contact the object surface, make the brush hair up end form a dynamic brush hair face of laminating object surface shape, along with the motion of brushing the object surface is wiped to the brush head, the continuous conversion atress state of brush hair drives the soft basement of elasticity and constantly produces the elastic deformation of different degrees thereupon, make the brush hair up end remain throughout and laminate with the object surface, let protruding and the depressed part in object surface can both obtain the effective cleanness of brush hair tip.

The corresponding elastic soft-base brushes are selected according to the degree of unevenness of the surfaces of objects to be cleaned, so that the surfaces of the objects can be better cleaned; for people with serious gingival atrophy and irregular teeth, the toothbrush with soft base material, thick soft base and low bristle density is selected; the softer the material of the elastic soft substrate, the smaller the force required by the downward movement of the bristles, and the smaller the force required by the downward movement of the bristles, so that the bristles can be deeply inserted into the concave parts on the surface of the cleaning object; the thicker the elastic soft substrate is, the more the downward stroke of the bristles is, and the deeper depressions can be cleaned by the bristles; the smaller the density of the bristles, the less the pressure is dispersed, the less the force required to cause the bristles to elastically deform downward, and the less force is applied to the brush head to cause the bristles to penetrate into the depressions.
