Description

Technical Field

[0001] This invention relates to the field of sanitary ware cleaning tools, specifically to an electric toilet brush that automatically supplies toilet cleaning liquid. Background Technology

[0002] Toilet brushes are a common tool for daily toilet cleaning. Traditional toilet brushes require users to manually squeeze toilet cleaner onto the brush head, which is inconvenient and easily gets hands dirty. Some toilet brushes on the market have automatic toilet cleaner dispensers, but most use independent water pumps or air pressure devices to deliver the cleaner, resulting in complex structures, high costs, and the viscous nature of the cleaner, which easily clogs the pump, leading to poor reliability. Furthermore, existing products do not allow users to stop the liquid supply during use, failing to meet the needs of "wet brushing followed by dry brushing" or "dry brushing only." Summary of the Invention

[0003] The purpose of this invention is to provide an electric toilet brush that is simple in structure, low in cost, highly reliable, and allows for the selection of whether to enable or disable automatic liquid supply.

[0004] The present invention adopts the following technical solution: An electric toilet brush with automatic toilet cleaner supply includes a handle and a brush head. The handle has a reservoir for storing toilet cleaner, and a filling port is located at the top of the handle. The brush head is rotatably connected to the lower end of the handle, and bristles are located at the bottom of the brush head. A motor is installed between the handle and the brush head, and its output shaft is connected to the brush head to drive its rotation. A battery is installed in a battery compartment inside the handle and is electrically connected to the motor via wires and a rotary switch. A liquid supply channel connects the reservoir to a dispensing chamber inside the brush head. A one-way valve is located in the liquid supply channel to prevent backflow. A liquid supply switch is located on the liquid supply channel between the reservoir and the one-way valve to control the opening and closing of the liquid supply channel. Multiple outlet holes are located at the bottom of the dispensing chamber, leading to the brush bristles. During operation, the user presses the rotary switch, which powers the motor to rotate the brush head. If the liquid supply switch is on, the centrifugal force generated by the rotating brush head directs the toilet cleaner from the dispensing chamber to the bristles. Simultaneously, a negative pressure is created in the dispensing chamber, automatically drawing in toilet cleaner from the storage chamber to replenish it. A one-way valve ensures that liquid can only flow from the storage chamber to the dispensing chamber, preventing backflow. If the liquid supply switch is off, the liquid supply channel is blocked, and no toilet cleaner is supplied even if the brush head rotates. Releasing the rotary switch stops the motor and automatically stops the liquid supply.

[0005] Compared with the prior art, the present invention has the following advantages: First, it uses the centrifugal force of the rotating brush head as the liquid supply power, eliminating the need for a separate pump device, resulting in a simple structure and low cost. Secondly, it has no easily clogged or corroded parts such as electric pumps, resulting in high reliability and long service life; Third, the automatic liquid supply can be enabled or stopped via the liquid supply switch, allowing for free switching between wet brushing and dry brushing modes; Fourth, stopping the rotation stops the liquid supply, eliminating the risk of leakage.

Detailed Implementation

[0007] like Figure 1 As shown, an electric toilet brush that automatically supplies toilet cleaning liquid includes a handle 1 and a brush head 2.

[0008] The handle 1 is generally elongated and cylindrical, with a liquid storage chamber 11 and a battery compartment 13 inside. The liquid storage chamber 11 is located in the middle of the handle 1 and is used to store toilet cleaner. The liquid storage chamber 11 is preferably made of transparent material, and has liquid level markings on the outside for easy observation of the remaining toilet cleaner. A filling port 12 is located at the top of the handle 1, and the filling port 12 has an openable sealing cap. The battery compartment 13 is located above the liquid storage chamber 11 and is used to install the battery 4.

[0009] The brush head 2 is rotatably connected to the lower end of the handle 1. The brush head 2 has a liquid dispensing chamber 22 inside, and multiple liquid outlet holes 23 are provided at the bottom of the liquid dispensing chamber 22. Brush bristles 21 are fixed at the bottom of the brush head 2, and the liquid outlet holes 23 lead to the brush bristles 21.

[0010] The motor 3 is installed between the handle 1 and the brush head 2, and the motor output shaft 31 is fixedly connected to the brush head 2. The battery 4 is installed in the battery compartment 13 and is electrically connected to the motor 3 through the wire 5 and the main switch 6. The main switch 6 is located on the outside of the handle 1 and is a push-button switch.

[0011] The liquid supply channel 7 connects the bottom of the liquid storage chamber 11 to the liquid distribution chamber 22. A one-way valve 8 is installed in the liquid supply channel 7, allowing liquid to flow from the liquid storage chamber 11 to the liquid distribution chamber 22 and preventing reverse flow. The liquid supply switch 9 is installed on the liquid supply channel 7, located between the liquid storage chamber 11 and the one-way valve 8. The liquid supply switch 9 is a toggle valve or a rotary valve, which the user can toggle or rotate to control the opening and closing of the liquid supply channel. When the liquid supply switch 9 is open, the liquid supply channel 7 is unobstructed, enabling automatic liquid supply; when the liquid supply switch 9 is closed, the liquid supply channel 7 is blocked, and even if the brush head 2 rotates, the toilet cleaner cannot flow out of the liquid storage chamber 11, thus achieving dry brushing mode.

[0012] To use, first open the filling port 12 and pour toilet cleaner into the storage chamber 11, then close the filling port 12. Depending on the needs, switch the supply switch 9 to the on or off position. Press the main switch 6; the battery 4 powers the motor 3, and the motor output shaft 31 drives the brush head 2 to rotate. If the supply switch 9 is on, the centrifugal force generated by the rotating brush head 2 throws the toilet cleaner in the dispensing chamber 22 towards the bristles 21, while simultaneously creating negative pressure in the dispensing chamber 22, automatically drawing toilet cleaner from the storage chamber 11. If the supply switch 9 is off, there is no toilet cleaner supplied, and the brush head 2 only performs dry brushing. The user inserts the brush head 2 into the toilet bowl, and the rotating bristles 21 clean. After cleaning, release the main switch 6; the motor 3 stops, and the supply automatically stops.

[0013] As a further improvement, the bottom of the dispensing chamber 22 may be equipped with an adjustable rotary valve to control the supply of toilet cleaner. The brush head 2 and the handle 1 may be detachably connected for easy replacement or cleaning of the brush head.

[0014] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. All equivalent variations and modifications made in accordance with the claims of the present invention shall still fall within the scope of the present invention.
