Description

A motorized scrubbing head

technical field

The utility model relates to a motorized scouring head, which belongs to the improvement of existing motorized brushes or manual brushes, such as toothbrushes, electric brushes, pneumatic brushes, surface cleaning equipment on industrial machinery, etc. For regular irregularities, the existing technology cannot effectively brush the stains in the pits, and at the same time, it can treat the stains on the plane, especially the stains in the grooves, with higher efficiency.

Background technique

Motorized brushes or manual brushes in the prior art, such as toothbrushes in daily life, or electric brushes, pneumatic brushes in industrial applications, surface treatment equipment on mechanical equipment, etc., have limited ability to deal with flat and uneven stains:

In industry, in order to clean the stains on the uneven concave surface, for example, to wipe off the uneven rust after rusting, it is often necessary to apply a lot of pressure on the motorized wiper, or even add a pressure device. Excessive scratches are caused, and even more time is needed for cleaning. If the concave surface is deep, there are many places that cannot be cleaned.

In daily life, for example, when brushing teeth, the concave surface of the irregular tooth surface of the molars and the concave position of the irregular tooth arrangement, the brushing method of various existing toothbrushes is to move or vibrate on the surface of the teeth by brushing the bristles, Therefore utilize the toothbrush of prior art to be difficult to clean teeth thoroughly and cleanly.

For example, a cleaning device that presses on the surface of an object and vibrates has very low efficiency in actually cleaning stubborn stains, and is only suitable for vibrating liquid stains. And when moving on the surface of an object, such as an electric toothbrush, the brush head moves left and right, forward and backward, forward and backward, or when an industrial high-speed rotating pressurized electric or pneumatic brush is cleaning, the bristle tips will be wiped. The brush bristles are deformed by force on the protruding surface, and a large part of the applied kinetic energy is lost due to the bending of the bristles. For the concave position, it is rubbed on the convex surface and cannot be effectively rubbed in at all. The inside of the sunken surface, so for the stains on the irregular sunken surface, of course, you can't wipe it off. If the sunken position is just in line with the wiping direction, you can barely wipe part of the sunken position, but it is useless for irregular sunken positions.

At the same time, through a large number of experiments, it was found that no matter how much force is used to press the brush to brush, the top of each bristle will bounce over the concave position at once during the lateral movement, and it cannot effectively brush the concave surface of different shapes. , in those concave positions that are just brushed, if you want to brush away stubborn stains on the concave surface, you need to brush for a long time or apply greater pressure to make the bristles go deep into the concave surface, so most of them will be on the convex surface. It will cause excessive wiping, resulting in energy loss and even product damage.

For the top of each bristle, the ability to remove the stains stuck to the concave position of the cleaning object, in addition to being inaccessible due to the sinking of the surface, will also be lost due to the stiffness of each bristle, because the general bristles are It is columnar and needle-shaped, and the bristles are made of elastic material. The bristles bend when they move laterally, so that the power is lost by the elasticity of the bristles, and the force of brushing away the stains becomes weaker, and the kinetic energy is not well absorbed. Effective transfer bristle tips for pushing away stuck-on stains. And if you use bristles with less elasticity and stronger rigidity, it may scratch the protruding surface too much, but at this time, the stain removal effect on the concave surface is still not much improved.

It has been found through the facts that household electric toothbrushes almost include a variety of brushing methods, but their cleaning power cannot effectively clean the tooth stains on the front teeth, the tooth stains in the gaps between the teeth, and the depressions on the tooth surfaces of large teeth. The stains in the interior, and the motorized brushes used for industrial surface cleaning, almost always rely on the abrasion of the protruding surface to wipe the concave surface.

Utility model content

The purpose of this utility model is to overcome the above-mentioned defects and provide a motorized scrubbing head. This utility model is aimed at all current cleaning tools and methods, which cannot perform cleaning more efficiently and quickly, nor can it completely clean the sunken position The largest part of the power of the motorized scouring head of the utility model is used as the scouring surface, and at the same time, it is faster and more effective than the prior art in removing regular or irregular uneven stubborn stains.

The technical solution of the utility model is as follows: a motorized scouring head, which is characterized in that it includes a scouring object, a scouring head, a supporting position, and a pushing position, and the scouring object is connected to a scouring head, so There is a specific support position on the above-mentioned scouring head, and the support position changes the composition ratio of the punching force and the lateral friction force through the change of its own position and mode, so as to generate different proportions of the momentum of the punching and rubbing. The number of push positions is one or more. After the push position receives the transmitted push force, it will cause the scouring head to generate swing power. The push position is matched with the push force introduced by the existing power transmission mechanism. Change to the power to push the scouring head to generate swing, and scouring the scouring object back and forth downward.

According to the utility model with the above-mentioned structure, it is also characterized in that the scourer is any one of a needle, a column, a block, a nail or any combination thereof, and is used for direct scouring To be used to clean the surface.

According to the utility model with the above structure, it is also characterized in that the arrangement of the scouring tips of the scouring objects can be one of flat row, zigzag, arc, wave, or any combination thereof.

According to the utility model with the above structure, it is also characterized in that an anti-scattering enclosure is provided around the scuffing object, and the anti-scattering enclosure is used to protect the scuffing object and exposes the scuffing object at one end .

According to the utility model with the above structure, it is also characterized in that the support position can be an axis or a non-axis, such as: a sliding mechanism (using a slider to support the method of a chute), a suspension mechanism (use non-rigid materials, support by means of hanging, etc.) and so on.

According to the utility model with the above structure, it is also characterized in that the driving force of the scouring head, for example, uses one-way power, such as: only pushing force, or only pulling force, or only twisting one side, or rotating power, etc. The method of pushing back with elastic force (such as: slingshot, shrapnel, elastic material, cam, etc.) resets the scouring head and waits for the next push.

As the utility model, one-way driving force can be used, and the slingshot elastic force is used to push back to the implementation mode. The pushing position is pushed by the one-way power to make the scouring head rush downward, and the top of the scouring object is scouring downward. When the one-way power disappears, the elastic force of the slingshot resets the scouring head, waiting for the next push.

As an embodiment of the shock-absorbing balance of the present invention, if the whole row of scouring objects is rushed downwards and upwards at once, the momentum will cause the brushes to swing up and down and make it uncomfortable to hold (considering that most motorized brushes are operated by hand) ), so the relative movement can be used to balance the impulse, that is, when a part of the brush is flushed downwards, a part of the brush is flushed upwards, so as to balance the impulse force for easy handling and use: one of the simple methods: to reduce the impact of the brush head and at the same time the whole downward Or the hand-held discomfort caused by upward swing, the support position 113 is arranged in the middle position of the rubbing head 111, and the purpose of reducing the swing force is achieved by using the leverage method, and the power is divided into left and right turns to rush down, so that the utility model is more hand-held. Stablize.

As another alternative, a motorized scouring head is characterized in that it includes a scouring object, a scouring head, a supporting position, and a pushing position, and the described scouring object is connected to a scouring head, and the described The support of the scouring head is a sliding structure, and the support of the scouring head is arranged in a housing. Through the chute in the housing, the composition ratio of the force of punching down and the force of horizontal rubbing is changed to produce different proportions of punching and rubbing. momentum, the said scouring head has a pushing position, and the pushing position will make the scouring head generate swing power after receiving the transmitted driving force. The wiping head generates swing power, and rubs the top of the rubbing object back and forth downward.

According to the utility model with the above structure, the physical impulse principle is used to make the scuffing object produce an impulse to punch down (or peck down) to the rubbing surface, so that the top of each scuffing thing can be continuously flushed and rubbed to the unevenness to be cleaned On the uneven surface, since its force is supported by the rigidity of the scuffing object, it can produce a very high-efficiency cleaning effect. Even if there is an irregular concave surface, the scuffing object can still scour from top to bottom to a deep position. A utility model can be designed in the form of replacement parts, or can be integrated with any motorized power source, such as magnetic, electric, motorized, pneumatic, etc., to form a whole piece of equipment or tool.

Detailed ways

As shown in Figure 1A, 1B, 2A, 2B and Figure 3, F is the direction of the force, and the shaded area is the stained area that will never be washed away. As can be seen from the figure, the wiping head of the prior art has very low efficiency in actually cleaning stubborn stains. When moving on the surface of the object, the tip of the bristles will be stressed at the protruding position of the rubbed surface to deform the bristles, and a large part of the applied kinetic energy will be lost by the bending of the bristles. Just wipe it off on the convex surface, and it can't effectively wipe into the inside of the concave surface at all, so for the dirt on the irregular concave surface, of course, the cleaning is not thorough.

As shown in Figures 4A, 4B, 5A, 5B and 6A, 6B, and 6C, the impulse principle of physics is used to make the bristles produce an impulse to punch (or peck) downward on the rubbing surface, so that the tops of each bristle can be continuously flushed and continuously flushed. Wipe on the uneven surface to be cleaned, because its force is supported by the stiffness of the bristles, so it can produce extremely high-efficiency cleaning effect, even if there are irregular concave surfaces, the bristles can still scrub from top to bottom to the deep position , the utility model can be designed in the form of replacing accessories, or can be integrated with any motorized power source, such as magnetic, electric, motorized, pneumatic, etc., to become a whole piece of equipment or tool.

As shown in Figures 7A, 7B, 7C, 7D, 7E, 7F, 7G, 7H and Figures 8A, 8B, 8C, 8D, 9A, 9B, 10A, 10D, 11A, 11C, and 12, the utility model's motorized scour The head is characterized in that it includes an scouring object 111, a scouring head 112, a supporting position 113, and a pushing position 114. The scouring object 111 is connected to a scouring head 112, and the scouring head 112 has A specific support position 113, the support position 113 changes the composition ratio of the punching force and the lateral friction force through the change of its own position and mode, and produces different proportions of the momentum of the punching and rubbing. The number of the pushing position 114 There may be one or more than one. After the push position 114 receives the transmitted push force 115, it will cause the impact head 112 to generate swing power. The push position 114 is matched with the push force 115 introduced by the existing power transmission , changed to the power to push the scouring head 112 to generate swing, and scouring the scouring object 111 back and forth downward.

According to the utility model with the above-mentioned structure, it is also characterized in that the scouring object 111 is any one of a needle, a column, a block, a nail or any combination thereof, and is used for direct scouring. Wipe to clean the surface.

According to the utility model with the above structure, it is also characterized in that the arrangement of the scouring tips of the scouring objects 111 can be one of flat arrangement, zigzag shape, arc shape, wave shape or any combination thereof.

According to the utility model with the above-mentioned structure, it is also characterized in that an anti-scattering shield 116 is provided around the scuffing object, and the anti-scattering shield 116 is used to protect the scuffing object 111 and is exposed at one end. Scrubs 111.

When the anti-scatter protection enclosure 116 is used for industrial purposes, it can strengthen the stamping strength and prolong the life of the scuffing objects. When the described anti-scattering enclosure 116 is used for toothbrushes, it can prevent the punching scuffs from the periphery. Pierce the skin of the mouth.

According to the utility model of above-mentioned structure, it is also characterized in that the power source 127 of different directions can be used by the power transmission mechanism 126, and can be designed into various scouring tools, equipment, equipment, instruments, toothbrushes, motorized wipes, Pneumatic rubbing, etc., as the most common power source, can be connected to the rubbing head through the power transmission mechanism 126 through the power of rotation, forward and reverse twisting, push-pull, etc.

As shown in Figures 7A, 7B, 7C, 7D, 7E, 7F, 7G, and 7H, the scouring head 112 of the present utility model is a group or multiple scouring heads assembled with scouring objects 111, through a specific support position 113, The change of the position of the axis changes the ratio of the punching force and the horizontal rubbing force, and produces different proportions of the momentum of punching and rubbing, so that the top of the rubbing object mounted on the rubbing head 112 generates more momentum, or The rubbing force is more, to be applied to different work, 122 is the motion locus of the brush tip, and what the brush tip motion locus 122 is tangent to the axis is the impulse momentum, and the centripetal is the momentum of rubbing.

Theoretically, when the upright direction of the impact object 111 is consistent with the direction of motion, the lateral friction force is zero, and the impact object 111 will push out all the power with its own stiffness, directly collide with the surface, and be compressed until it reaches its limit and buckles. The abrading point is then caused to bounce off due to the force of buckling.

As the utility model, one-way driving force can be used, and elastic force can be used to push back (such as: slingshot, shrapnel, elastic material or elastic structure, etc.), as shown in Figures 8A, 8B, 8C, 8D and 11A, 11C, The pushing position 114 is promoted by the one-way power 115, so that the rubbing head 112 is dashed downward, and the top of the rubbing object (111) is rubbed downward. When the one-way power disappears, the elastic force of the slingshot 124 resets the rubbing head, waiting to be pushed next time.

As a schematic diagram of the principle of the shock-absorbing balance of the present invention, as shown in Figures 9A and 9B, if the entire row of brush heads is rushed downwards and upwards at the same time, the momentum will make the brushes swing up and down and be uncomfortable to hold (considering most motorized brushes). The brushes are all operated by hand), so the relative movement is used to balance the impulse, that is, when a part of the brush rushes down, a part of the brush rushes up to balance the impulse force for easy handling and use. In order to reduce the hand-holding discomfort caused by the simultaneous downward or upward swing of the scouring head 112, the support position 113 is set at the near middle position of the scouring head, and the leverage method is used to reduce the swing force, and the driving force 115 Promoting the pushing position 114 by turns from left to right will make the rubbing head 112 generate swinging power, making the utility model more stable to hold.

As an embodiment of the shock-absorbing balance of the present invention, as shown in Figures 10A, 10B, 10C, 10D, 10E, and 10F, in order to reduce the hand-holding discomfort caused by the simultaneous downward or upward swing of the scouring head, the support 113 The swing center axis is set near the middle of the scouring head, and the leverage method is used to reduce the swing force. The two cams 125 alternately impact the pushing position 114 on both sides of the scouring head 112, and apply the power 115 to the scouring head respectively. The left and right sides of 112 make the utility model hold more stable.

As another alternative, as shown in Figures 11A, 11B, and 11C, 11A is a schematic diagram of the combined structure of the shell and the scouring head, 11B is a B-B sectional view, and the support 113 is hidden in the shell 123 in a sliding manner to make the scouring head 112 slide . An embodiment that does not use a shaft for support and uses a single-push power source. A motorized scouring head, comprising a scouring object 111, a scouring head 112, a supporting position 113, and a pushing position 114, wherein the scouring object 111 is connected to a scouring head 112, and the scouring The supporting position 113 of the head 112 is a sliding structure, and the supporting position 113 is hidden in the casing 123 in a sliding manner, so that the rubbing head 112 slides inside. Through the chute in the shell 123, the composition ratio of the force of punching down and the force of lateral rubbing is changed, so as to generate momentums of punching and rubbing in different proportions. The scouring head uses a one-way driving force 127, through the power transmission mechanism 126, the driving force 115 is transmitted to the pushing position 114, and after the pushing position 114 receives the transmitted driving force 115, the scouring head 112 will generate The power of falling on the left uses the elastic force to push the slingshot 124 back, so that the rubbing head 112 returns to the original position of falling on the right.

The utility model is a motorized scouring head capable of cleaning various uneven sunken stains, which mainly uses a power source 127 in any direction to generate a driving force 115 through various power transmission mechanisms 116 to push the pushing position 114 , to make the scouring head 112 swing, thus causing the top of the scouring object 111 to move from up to down to the surface to be treated. The tip of the rubbing object leaves the surface and hits the surface to be rubbed one by one. The rubbing object 111 uses most of the original maneuvering force through the action of the rubbing object similar to a straight thrust, and inserts the momentum into the rubbed surface. On the stains, since a large part of the recoil force at the top of the scouring object is borne by the material of the scouring object and transmitted back to the strong scouring head, the energy of the scouring object tip to push away the stain is very large.

In addition, through the action of a little lateral movement when it is flushed down, the top of the rubbing object produces continuous flushing and continuous rubbing actions. Since the action of rubbing dirt in the utility model is supported by the speed and rigidity of the rubbing object, It can produce incomparable cleaning performance than traditional brush sweeping. Even if there is an irregular concave surface, the action of the scoured object is from top to bottom, from leaving to impact, so it can scour to a deep position, and if the scour head is moved properly, the stains on the concave surface and even Stains in partially covered areas can also be cleaned by scrubbing.

The utility model can use different materials as scouring objects, and can be applied to various fields such as: metal rust removal, surface cleaning, oral cavity cleaning, etc., can cooperate with various powers and can be made into various sizes, and can be used for lightweight Portable tools such as toothbrushes, engineering processing such as electric steel wire wipes, pneumatic steel wire wipes, fixed machinery such as stain production lines that scour the surface of plates, etc.

The scouring head of the utility model can be in any shape: as circular, square, rectangular, etc., or installed outside the roller or in the cylinder.

The protruding arrangement at the top of the scouring head of the utility model can be any arrangement except the flat arrangement: such as arc type, wave type, zigzag type; or a multi-layer arrangement of mixed different arrangement modes and can be used Special arrangements are made for the field of work.

The scouring head of the utility model is a mechanism for processing flat or uneven surfaces by scouring in a straight line or a curve, such as a hand-held, fixed or various mechanical components.

The scouring head of the utility model uses the impulse of the brush to push away the stains, which may make the brush unstable, and can use the balance movement of the equivalent force, such as a lever to balance the impulse.

The scouring head of the utility model can be simplified into a single scouring head without using an optimization scheme, such as not using an anti-scattering shield. Or it can be integrated into multiple groups of flushing heads; or it can change the rubbing objects into other materials, such as: solid sharp objects can be used for various flat or concave-convex surface scratches; the utility model is replaced by sandy materials for It can be used for grinding, etc.; or it can be replaced with a block for scraping, etc.

The utility model adds fluid material when rubbing, and can smear the uneven surface, so as to achieve the situation that the fluid material cannot be hidden in the concave position when it is sprayed on the uneven surface in the past.
