Description
Technical Field
[0001] This utility model belongs to the technical field of floor brush improvement, specifically relating to a floor brush that can automatically enter an upright state and lock when the connector rotates toward the floor brush body, and automatically unlock when the connector rotates away from the floor brush body. Background Technology
[0002] A common floor brush includes an interconnected connector and a brush body. The connector can rotate relative to the brush body. The brush body has a rotation space at its rear, which is U-shaped. The connector can rotate within this rotation space. A stop is provided on the upper surface of the bottom of the U-shape of the rotation space. When the connector is upright, the stop prevents it from tilting severely towards the brush body. Floor brushes typically have a working state and a non-working state. When in the working state, the angle between the connector and the brush body is greater than 90°. When in the non-working state, the connector usually keeps the brush upright, but there is no locking between the connector and the brush body, making the connector prone to tipping over. Therefore, the connector needs to be placed against a wall. This type of floor brush is inconvenient because the connector is prone to tipping over.
[0003] To this end, we have developed a floor brush that can automatically enter an upright state and lock when the connector rotates toward the main body of the floor brush, and automatically unlock when the connector rotates away from the main body of the floor brush. Summary of the Invention
[0004] The purpose of this utility model is to provide a floor brush that can automatically enter an upright state and lock when the connector rotates toward the main body of the floor brush; and automatically unlock when the connector rotates away from the main body of the floor brush.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a floor brush capable of standing upright, comprising a connector and a floor brush body interconnected; the connector is rotatable relative to the floor brush body; a rotation space is provided at the rear of the floor brush body; the rotation space is U-shaped; the connector is rotatable within the rotation space; a stop is provided on the upper surface of the bottom of the U-shape of the rotation space; when the connector is upright, the stop prevents it from tilting severely towards the floor brush body; a rotating hook is provided on one side of the lower part of the connector, and a barb is provided on the lower part of the upper end face of the rotating hook; a locking block is provided on one side of the rear part inside the floor brush body, and a spring is provided between the locking block and the front part of the floor brush body; a locking protrusion is provided on the inner side of the upper end face of the locking block; when the connector rotates towards the floor brush body, the barb on the rotating hook can hook the locking protrusion, thereby preventing the connector from tilting away from the floor brush body.
[0006] Preferably, a rotating block is provided on the other side of the lower part of the connector; a normally closed switch is provided on the other side of the rear part inside the floor brush body; the normally closed switch is used to control the power supply to and off of the drive motor of the floor brush inside the floor brush body; a contact is provided on the inner side of the normally closed switch, and when the contact is closed, the normally closed switch is open; when the connector rotates toward the floor brush body, the rotating block will squeeze the contact to close it, at which time the normally closed switch is open.
[0007] Preferably, the rotating hook and the rotating block are mounted on the same fixed axis.
[0008] Preferably, both the rotating hook and the rotating block rotate together with the connector.
[0009] Preferably, there is no relative angular change between the rotating hook and the rotating block and the connector.
[0010] Compared with the prior art, this utility model provides a floor brush that can stand upright, which has the following beneficial effects:
[0011] The upright floor brush of this invention automatically enters and locks into an upright state when the connector rotates toward the brush body; it automatically unlocks and transitions from an upright state to a non-upright state, i.e., a free-working state, when the connector is upright. Furthermore, the drive motor of the floor brush inside the brush body automatically cuts off power when the connector is upright, resulting in a high degree of automation, reduced energy consumption, and lower operating costs!
