Description

Flexible endless belt storage device for surface cleaning

Technical Field

The present disclosure relates to a flexible endless belt storage device for surface cleaning.

Background

Wet surface cleaning apparatuses are suitable for cleaning hard floor surfaces, such as ceramic tiles, hardwood floors, soft carpeted surfaces, and the like.

When the wet type surface cleaning equipment cleans the surface to be cleaned, the cleaning liquid is firstly conveyed to the cleaning module and is applied to the surface to be cleaned through the cleaning module, and when the cleaning module and the surface to be cleaned generate relative motion, the surface to be cleaned is cleaned.

The crawler-type cleaning device can effectively improve the contact area between the cleaning module and the surface to be cleaned, so that the wet-type surface cleaning equipment has a better cleaning effect. However, the flexible endless belt of the track type cleaning apparatus is kept in a track type state in a state of transportation or the like. At this time, since the flexible annular belt includes the glue, the glue is cooled and re-solidified under a high-temperature and high-humidity environment (for example, under the conditions of marine transportation or indoor sun irradiation, etc.), if the storage shape of the flexible annular belt has a curvature change, for example, the flexible annular belt is configured in the surface cleaning device for storage (integral storage), or the flexible annular belt is placed naturally (linear storage), the flexible annular belt is solidified according to the storage shape, and this uneven-curvature solidification causes severe shaking of the surface cleaning device during startup operation and when the flexible annular belt is driven to rotate.

Moreover, when the fluff of the flexible annular belt is unevenly distributed due to pressure, the compression amount of the fluff is different, the thickness of the crawler belt is uneven, a user starts the machine to operate, and when the flexible annular belt is driven to rotate, the surface cleaning equipment can shake seriously, and even the user returns goods.

The number of the first rolling elements is at least two, and at least one of the first rolling elements is located at one side of a plane formed by the rotation axis of the first rotation shaft 110 and the rotation axis of the second rotation shaft 120, and at least one of the first rolling elements is located at the other side of the plane, and a direction of a force applied to the support member 140 by the first rotation shaft 110 may be considered to be located in the plane, and when the two first rolling elements are located at both sides of the plane, the first rotation shaft 110 may be stably supported by the two first rolling elements formed at both sides of the plane.

Here, the first rolling element is located at one side of the plane, which means that a contact point of the first rolling element with the first rotation axis 110 is located at one side of the plane.

More preferably, the first rotation shaft 110 includes a first groove portion 111, and the first support 143 of the support assembly 140 receives the first groove portion 111 and brings the first rolling body into surface contact with a bottom wall of the first groove portion 111.

When different first rolling bodies are used, different first groove portions 111 may be formed, for example, when a first rolling body is a roller portion, a bottom wall surface of first groove portion 111 may be formed as a cylindrical surface so that the roller portion can roll on the cylindrical surface, and accordingly, when the first rolling body is a ball, a cross section of a bottom wall surface of first groove portion 111 may be arc-shaped, for example, semicircular, so that the ball can roll on the bottom wall surface of the first groove portion.

The first support 143 of the support member 140 is formed with a first opening 141, a distance of the first opening 141 is equal to or slightly greater than a diameter of a circle on which a bottom wall surface of the first groove portion 111 is located, and the first groove portion 111 is received in the first opening 141.

For example, when the bottom wall surface of the first groove section 111 is formed as a cylindrical surface, the distance of the first opening 141 is equal to or slightly larger than the diameter of the cylindrical surface; when the cross section of the bottom wall surface of the first groove portion 111 is arc-shaped, the diameter of the first opening 141 is equal to or slightly larger than the diameter of the bottom wall surface at the maximum diameter, so that the first rotation shaft 110 can be disposed in the first opening 141.

At least a part of the first rolling elements is located in a space formed by the first opening 141, whereby the first rolling elements can be in surface contact with the bottom wall of the first groove portion 111.

Preferably, the first groove portion 111 is located at a position between both end portions of the first rotation axis 110, and preferably, the first groove portion 111 is located at a middle position of the first rotation axis 110.

The second supporting portion 149 of the present disclosure is described below in conjunction with the first supporting portion 148, and the structure of the second supporting portion 149 is relatively similar to that of the first supporting portion 148, and based on this, a brief description will be given about the structure of the second supporting portion 149.

Accordingly, the second support portion 149 includes a second rolling body rotatably disposed at the second support member 144; preferably, the second rolling element includes a roller portion having a rotation axis parallel to a rotation axis of the second rotation shaft 120.

Of course, the second rolling element may be formed as a ball portion.

Accordingly, the number of the second rolling bodies is at least two, and at least one of the second rolling bodies is located at one side of a plane formed by the rotational axis of the first rotating shaft 110 and the rotational axis of the second rotating shaft 120, and at least one of the second rolling bodies is located at the other side of the plane.

Here, the second rolling element is located at one side of the plane, which means that the contact point of the second rolling element with the second rotation shaft 120 is located at one side of the plane.

The second rotating shaft 120 includes a second groove portion 121, and the second supporter 144 of the support assembly 140 receives the second groove portion 121 and brings the second rolling body into surface contact with a bottom wall of the second groove portion 121.

Moreover, the shape of the second groove 121 is also related to the shape of the second rolling element, for example, when the second rolling element is a roller part, the bottom wall surface of the second groove 121 may be formed as a cylindrical surface; accordingly, when the second rolling body is a ball, the bottom wall surface of the second groove portion 121 has an arc-shaped cross section, for example, a semicircular cross section.

The second support 144 of the support member 140 is formed with a second opening 142, the distance of the second opening 142 is equal to or slightly greater than the diameter of the circle on which the bottom wall surface of the second groove portion 121 is located, and the second groove portion 121 is received in the second opening 142.

For example, when the bottom wall surface of the second groove portion 121 is formed as a cylindrical surface, the distance of the second opening 142 is equal to or slightly larger than the diameter of the cylindrical surface; when the bottom wall surface of the second groove portion 121 has an arc-shaped section, the diameter of the second opening 142 is equal to or slightly greater than the diameter of the bottom wall surface at the maximum diameter, so that the second rotation shaft 120 can be disposed in the second opening 142.

Also, at least a portion of the second rolling body is positioned in a space formed by the second opening 142, thereby being contactable with the second groove portion 121 via the second rolling body.

In the present disclosure, the second groove portion 121 is located at a position between both end portions of the second rotation shaft 120, for example, the second groove portion 121 is located at a middle position of the second rotation shaft.

The inner wall surface of the flexible annular band 130 has a predetermined interval from the support member 140, that is, the support member 140 does not affect the rotation of the flexible annular band 130.

In the present disclosure, as shown in fig. 13, the first rotating shaft 110 or the second rotating shaft 120 is provided with a flange portion 122, and the flange portion 122 is located at one end of the first rotating shaft 110 or the second rotating shaft 120 away from the supporting bracket 150, so that the flexible endless belt 130 can be prevented from being deviated by the flange portion 122. In the preferred example shown in fig. 13, the flange portion 122 is located at one end of the second rotating shaft 120, and it should be understood by those skilled in the art that the flange portion may be formed on the first rotating shaft 110, and in this case, the flange portion is not formed on the second rotating shaft 120, that is, the flange portion 122 is provided on one of the first rotating shaft 110 and the second rotating shaft 120, so that the processing cost of the first rotating shaft 110 and the second rotating shaft 120 can be reduced.

The cleaning base may further include a driving means capable of driving the first rotating shaft 110 or the second rotating shaft 120 to rotate and rotating the flexible endless belt 130.
