As shown in fig. 1, a floor brush according to an embodiment of the present invention includes:

a base 1;

the rolling brush 2 is connected to the base 1, and the rolling brush 2 is used for cleaning the ground;

adjusting part 3, adjusting part 3 rotate to be connected on base 1, and adjusting part 3's axis of rotation is parallel with ground, and adjusting part 3 uses the axis of rotation to rotate as the center with the distance between adjusting base 1 and the ground, and then reduces the effort that the user exerted when withdrawing round brush 2.

The floor brush according to the embodiment of the present invention is added with the adjustment assembly 3 to reduce the force applied when the user withdraws the floor brush, compared to the conventional floor brush. In the use, round brush 2 rotates forward and with ground contact, make the scrubbing brush have the trend of forward motion, the user pushes away the scrubbing brush before and cleans ground, the withdrawal is so that clean other regions on ground with the position of adjustment scrubbing brush, the in-process of withdrawal, round brush 2 lasts forward rotation, the motion trend direction and the withdrawal direction of scrubbing brush are opposite, through the effort of applying when adjusting part 3 in order to reduce the user withdrawal scrubbing brush, improve user's experience and feel, increase the flexibility when scrubbing brush withdraws. The rotation axis of the adjusting component 3 is parallel to the ground, and the adjusting component 3 rotates by taking the rotation axis as a center, so that the size of the adjusting component 3 in the direction perpendicular to the ground is changed, and further, the distance between the base 1 and the ground is changed.

It should be noted that, in order to reduce the force applied when the user withdraws the floor brush, there are the following ways: firstly, under the condition that the rotation direction of the rolling brush 2 is not changed, a driving source is additionally added to provide a retreating driving force for the floor brush, and when the first mode is adopted, the driving source can be started only when the floor brush is retreated or can be started when the floor brush is pushed forwards and retreated, but the movement directions of the driving source are opposite when the floor brush is pushed forwards and retreated and the driving source needs to be matched with a sensor for use; secondly, a sensor is added, and the rotation direction of the rolling brush 2 is changed by detecting the movement direction of the floor brush through the sensor, so that the floor brush has the tendency of withdrawing; and thirdly, changing the friction force between the floor brush and the ground. The above manner is only used as an example and is not used to limit the protection scope of the present invention.

In some embodiments of the present invention, the first, second and third ways can reduce the force applied by the user when the floor brush is retracted, but the first and second ways involve changes in the circuitry and operating procedures, which increases the cost of the floor brush, and therefore, in one embodiment, the third way is selected. The third way is to reduce the force applied by the user when withdrawing the floor brush by changing the friction between the floor brush and the floor. When two objects, which are in contact with each other and pressed against each other, move or have a tendency to move relative to each other, a force is generated on the contact surfaces that counteracts the relative movement or the tendency to move relative to each other, which force is called a friction force. The in-process round brush 2 that pushes forward at the scrubbing brush relative ground cleans ground, and frictional force between scrubbing brush and the ground is useful frictional force this moment, and at the in-process that the scrubbing brush withdraws relatively ground, the position that the scrubbing brush is located need be adjusted, and frictional force between scrubbing brush and the ground this moment is harmful frictional force, and useful frictional force needs to increase, and harmful frictional force needs to reduce. The means for increasing the beneficial friction force is generally realized by the following methods: the first is to increase the roughness of the contact surface, and the magnitude of the friction force is positively correlated with the magnitude of the roughness; secondly, increasing pressure, wherein the magnitude of the friction force is in positive correlation with the magnitude of the pressure; and thirdly, changing rolling friction into sliding friction. The means for reducing the harmful frictional force is generally implemented by the following methods: first, changing sliding friction to rolling friction, a manner used in the prior art; second, the contact surfaces are separated; thirdly, the pressure is reduced, and the magnitude of the friction force is in positive correlation with the magnitude of the pressure; fourthly, the roughness of the contact surface is reduced, and the magnitude of the friction force is in positive correlation with the magnitude of the roughness. In one embodiment, the second way is used to reduce the detrimental friction between the floor brush and the floor. The adjusting component 3 is movably connected to the base 1, and may be connected to the front side, the left side, the right side or the lower side of the base 1, and in one embodiment, in order to reduce the volume of the floor brush, the adjusting component 3 is disposed on the lower side of the base 1, that is, connected to the side of the base 1 facing the ground. One end of the adjusting component 3 is connected to one side of the base 1 facing the ground, the other side of the adjusting component is in contact with the ground, the distance between the base 1 and the ground is adjusted through the adjusting component 3, namely the distance between the base 1 and the ground is adjusted to reduce the acting force between the rolling brush 2 and the ground when the rolling brush is withdrawn, and at least part of the contact surface between the rolling brush and the ground is separated.

Wherein, the quantity of adjusting part 3 can be a set, two sets or multiunit, and in one embodiment, adjusting part 3 is provided with two sets ofly, and two sets of adjusting part 3's structure is the same completely, the symmetry sets up respectively in the both sides of base 1. Two sets of adjusting part 3 carry out synchronous the adjusting to the different positions of scrubbing brush to keep the distance between scrubbing brush both sides and the ground to change in step.

In some embodiments of the present invention, the driving source may be additionally added to provide the backward driving force to the floor brush according to the foregoing, but in order to reduce the weight of the floor brush, the production cost and the electrical failure rate, the adjustment of the distance between the base 1 and the ground is achieved using a mechanical structure. The adjusting assembly 3 includes a connecting member 31 and a movable member 32, a first end 311 of the connecting member 31 is rotatably connected to the base 1 by using a rotation axis as a center, a second end 312 of the connecting member 31 is connected to the movable member 32, the movable member 32 rotates relative to the base 1 by using the rotation axis as a rotation center through a friction force between the adjusting assembly 3 and the ground, and further, a distance between the base 1 and the ground is adjusted. Rely on the frictional force between adjusting part 3 and the ground to adjust the distance between base 1 and the ground, need not additionally to increase driving source drive adjusting part 3 and rotate, along with the removal synchronization of scrubbing brush goes on during adjusting part 3's rotation, simple structure does not relate to complicated circuit and control procedure, and simple structure is reliable, and the cost is lower. The movable member 32 rotates relative to the base 1 about the rotation axis as a rotation center to adjust the distance between the base 1 and the ground. During the forward pushing process of the floor brush, the friction force between the floor and the base 1 needs to be increased to enhance the cleaning capability of the floor brush, and the distance between the base 1 and the floor needs to be gradually reduced along with the forward pushing process of the floor brush. During the process of withdrawing the floor brush, the friction force between the floor brush and the ground is required to be reduced, so that the acting force applied by the user is reduced, and as the floor brush is withdrawn, the distance between the base 1 and the ground is required to be gradually increased so as to gradually separate the contact surface between the floor brush and the ground. Therefore, when the connection member 31 is perpendicular to the ground, the distance between the ground and the base 1 is maximized; when the connecting piece 31 rotates to the maximum angle relative to the base 1, the distance between the ground and the base 1 is minimum; the distance between the ground and the base 1 is in an intermediate position between maximum and minimum when the connecting member 31 is not perpendicular to the ground and is not rotated to the maximum angle. It can be determined that, as the floor brush is pushed forward, the rotation direction of the connecting member 31 is opposite to the movement direction of the floor brush to reduce the distance between the base 1 and the floor, and when the distance between the floor and the base 1 is minimum, it is at the first limit position; with the floor brush retracted, the direction of rotation of the link member 31 is reversed to the direction of travel of the floor brush to increase the distance between the base 1 and the floor, when the distance between the floor and the base 1 is at its maximum, to a second extreme position.

In some embodiments of the present invention, the rotation angle of the connecting member 31 is related to the cleaning ability of the floor brush by pushing forward and the flexibility of the floor brush by withdrawing, and the rotation angle needs to be kept within a certain range, and the rotation angle can be set according to the actual requirement.

In some embodiments of the invention, a stop structure may be provided on the connecting member 31 to indicate that the limit position has been reached when the adjustment assembly 3 interferes with its contact. The self-structure of the base 1 can be used as a limiting structure, and when the limiting structure is in contact with the self-structure of the base 1 and interferes, the limiting position is shown to be reached. As shown in fig. 3, 4, 6 and 7, in one embodiment, the limit structure is provided on the base 1. The scrubbing brush still includes first locating part 11, and first locating part 11 is connected on base 1, and when the distance between base 1 and the ground was the biggest, connecting piece 31 and first locating part 11 contacted, and connecting piece 31 is in the second extreme position, and the continuation of restriction connecting piece 31 rotates, avoids the continuation of connecting piece 31 to rotate and causes the damage of adjusting part 3.

In some embodiments of the present invention, when the distance between the base 1 and the ground is the minimum, the rotation limitation of the connecting member 31 in both directions can be limited by the self structure of the base 1 or by adding a limiting structure. As shown in fig. 3, 4, 6 and 7, in an embodiment, the floor brush further includes a second limiting member 12, the second limiting member 12 is connected to the base 1, when the distance between the base 1 and the ground is the minimum, the connecting member 31 is in contact with the second limiting member 12, the connecting member 31 is at the first limit position, the connecting member 31 rotates between the first limiting member 11 and the second limiting member 12 to adjust the distance between the base 1 and the ground, and a range formed by a side of the first limiting member 11 and a side of the second limiting member 12 facing the connecting member 31 is a rotation range of the connecting member 31. The first limiting member 11 and the second limiting member 12 may be block-shaped structures, rod-shaped structures, or plate-shaped structures.

The first limiting member 11 and the base 1 may be detachably connected, for example, screwed or clamped, or may be non-detachably connected, and the first limiting member 11 and the base 1 are integrated. Similarly, the second limiting member 12 and the base 1 may be detachably connected, for example, screwed or clamped, or may be non-detachably connected, and the second limiting member 12 and the base 1 are integrated.

In some embodiments of the present invention, when the connecting member 31 is located at the first limit position or the second limit position, the contact between the connecting member 31 and the second limiting member 12 or the first limiting member 11 is a rigid contact, which is likely to cause damage or fracture of the connecting member 31. Therefore, the first stopper 11 and the second stopper 12 are provided with the buffer members on the sides facing the connecting member 31, and the buffer characteristics of the buffer members are used to absorb the acting force of the rigid contact, so that the contact between the connecting member 31 and the second stopper 12 or the first stopper 11 is softer than the rigid contact. The buffer piece can be made of rubber, silica gel and the like.

In some embodiments of the present invention, during the process of pushing or withdrawing the floor brush forward, the movable element 32 and the connecting element 31 rotate synchronously relative to the base 1, and the movable element 32 and the connecting element 31 may rotate relatively to each other, either rotationally or non-rotationally, and may be fixed in relative positions by means of adhesion, welding or screwing. In one embodiment, the movable member 32 is pivotally connected to the connecting member 31, which further reduces the friction between the movable member 32 and the ground, and increases the flexibility of the floor brush when it is retracted.

In some embodiments of the present invention, as shown in fig. 3, 4, and 6 to 9, the connecting element 31 includes a support 313, a first rotating shaft 314, and a second rotating shaft 315, the support 313 is Y-shaped, a first end 311 of the support 313 is rotatably connected to the base 1 through the first rotating shaft 314, an axis of rotation is an axis of the first rotating shaft 314, and the movable element 32 is rotatably connected to a second end 312 of the support 313 through the second rotating shaft 315.

In some embodiments of the present invention, the movable element 32 may be a rolling element such as a one-way wheel, a universal wheel or a ball, when the movable element 32 is a one-way wheel, a universal wheel or a ball, the one-way wheel, the universal wheel or the ball is rotatably connected to the second end 312 of the connecting element 31 through the second rotating shaft 315, the second rotating shaft 315 is parallel to the ground, the adjusting element 3 rotates relative to the base 1, and along with the forward pushing or the backward withdrawing of the floor brush, the movable element 32 rotates relative to the ground around the second rotating shaft 315 as a rotation center, so that rolling friction is generated between the movable element 32 and the ground, and further friction between the movable element 32 and the ground is reduced, an acting force applied when a user withdraws the floor brush is reduced, and flexibility of the floor brush is improved. The movable member 32 may also be a combination of a one-way wheel, a universal wheel or a ball, for example, the movable member 32 is a combination of a one-way wheel and a ball, the ball is rigidly connected to the connecting member 31, the one-way wheel is rotationally connected to the second rotating shaft 315, the second rotating shaft 315 is rigidly connected to the ball through a connecting rod, and the one-way wheel can rotate around the second rotating shaft 315, where the positions of the ball and the one-way wheel are interchangeable. The combination of the universal wheel and the ball and the combination of the one-way wheel and the universal wheel can refer to the combination of the one-way wheel and the ball. As shown in fig. 3, 4, 6-9, the movable member 32 is a one-way wheel.

In some embodiments of the present invention, the movable element 32 may be outside the base 1, or may be partially or completely located inside the base 1, as shown in fig. 1 to 7, in order to reduce the volume of the floor brush, the base 1 is recessed away from the ground to form a receiving cavity 15, and at least part of the adjusting component 3 is located inside the receiving cavity 15. Set up adjusting part 3 to half hidden, the volume of furthest reduction scrubbing brush to be convenient for the user accomodate and deposit.

In some embodiments of the present invention, the adjustment assembly 3 is rotatably connected to the base 1, but is detachably connected to the base 1, so that the user can replace, inspect and maintain the adjustment assembly 3. In addition, in the cleaning process, impurities such as dust and hair easily enter the accommodating cavity 15 to cause that the adjusting component 3 cannot adjust the distance between the ground and the base 1, and the accommodating cavity 15 and the adjusting component 3 can be thoroughly cleaned by detaching the movable piece 32 and the connecting piece 31, so that the adjusting component 3 can be always kept in a normal working state.

In some embodiments of the present invention, as shown in fig. 1, 2 and 5, the base 1 is provided with at least one roller rotatably connected to a rear end of the floor brush to increase flexibility of the floor brush during forward and backward movements and reduce harmful frictional force between the floor brush and the floor. In one embodiment, two rollers are provided, namely a first roller 13 and a second roller 14, and the first roller 13 and the second roller 14 are symmetrically arranged on two sides of the base 1.

In some embodiments of the present invention, the adjusting assembly 3 may be disposed in front of the base 1 and may also be disposed behind the roll brush 2. It can be understood that the length and the rotation angle of the connecting member 31 and the setting position of the adjusting assembly 3 all have an influence on the adjustment of the distance between the base 1 and the ground, and the above-mentioned matters can be reasonably set according to the needs of actual situations, and will not be described herein again.
