Description

Technical Field

[0001] This utility model relates to the field of fully automatic toothbrush technology, specifically a liquid diversion device. Background Technology

[0002] A fully automatic toothbrush is a highly automated oral cleaning device that goes beyond the functions of a traditional handheld electric toothbrush. It integrates robotic arms or other automated components to replace manual operation.

[0003] Chinese invention patent CN109700556A, published on May 3, 2019, discloses a fully automatic electric toothbrush. This electric toothbrush includes a U-shaped toothbrush cover, a housing, a vibrating motor, a water pump, a water outlet tank, a water suction pump, a water inlet tank, and a power supply. The housing houses the vibrating motor, water pump, water outlet tank, water suction pump, water inlet tank, and power supply. The shaft of the vibrating motor is fixed to the U-shaped toothbrush cover. The water outlet of the water pump is connected to the U-shaped toothbrush cover, the water inlet of the water pump is connected to the water outlet tank, the water inlet of the water suction pump is connected to the U-shaped toothbrush cover, and the water outlet of the water suction pump is connected to the water inlet tank. The power supply is electrically connected to the motors of the vibrating motor, the water pump, and the water suction pump. This invention uses two water pumps to inject and suction water into the U-shaped toothbrush cover, eliminating the need for the user to drink and spit water, thus improving brushing efficiency, saving water, and making brushing more comfortable and easier.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the fluid pipeline of the existing fully automatic toothbrush is a single inlet and outlet. This means that multiple pipelines are needed to transport clean liquid and contaminated liquid. At the same time, the flow rate is affected by the pipe diameter. A large pipe diameter results in large deformation resistance during use, making it difficult to conveniently transport liquid for brushing teeth. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that the fluid pipeline of existing fully automatic toothbrushes is a single inlet and outlet, which requires multiple pipelines to transport clean liquid and contaminated liquid. At the same time, the flow rate is affected by the pipe diameter, and a large pipe diameter results in large deformation resistance during use, which makes it difficult to transport liquid for brushing teeth. The invention provides a liquid diversion device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention discloses a liquid diversion device comprising a first diversion hood and a second diversion hood that are interlocked with each other; a plurality of inner inlet and outlet pipes are connected and fixedly connected to the first diversion hood; a plurality of outer inlet and outlet pipes are connected and fixedly connected to the second diversion hood; a first groove is formed inside the first diversion hood; a first limiting cover is fixedly connected to the first groove; an elastic baffle is inserted inside the first limiting cover; and a through hole is formed on the elastic baffle for connecting the inner inlet and outlet pipes.

[0008] Furthermore, the elastic baffle is provided with a clearance groove for the outer inlet / outlet pipe.

[0009] Furthermore, a second groove is provided on the second shroud corresponding to the first groove.

[0010] The liquid diversion device provided by this utility model has the following beneficial effects:

[0011] 1. This utility model features an internal area and structure that facilitates easy installation, disassembly, and cleaning through the interlocking of a first and a second diversion hood. The first diversion hood has two internal inlet / outlet pipes fixedly connected to it, while the second diversion hood has four external inlet / outlet pipes fixedly connected to it. A first groove is formed within the first diversion hood, creating a passage between the first groove and the second diversion hood, allowing liquid to pass through. A first limiting cover is fixedly connected within the first groove. An elastic baffle made of silicone is inserted into the first limiting cover. A through hole is formed on the elastic baffle connecting the internal inlet / outlet pipes. Through the elastic baffle and the through hole, one internal inlet / outlet pipe can connect to two external inlet / outlet pipes, thus achieving two pathways: one for clean water and the other for wastewater, without interference. This allows for continuous liquid circulation for brushing when used in a fully automatic toothbrush.

[0012] 2. This utility model uses a clearance groove to connect the two outer inlet and outlet pipes to the through hole on the elastic baffle, thereby realizing the connection between one inner inlet and outlet pipe and two outer inlet and outlet pipes, realizing a flow path that is divided into two or combined into one. This can effectively reduce the discharge velocity of the outer inlet and outlet pipes, so as not to generate impact pressure that will damage the oral cavity and gums. Attached Figure Description

[0019] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0022] Please see Figure 1-4 As shown, a liquid diversion device includes a first diversion hood and a second diversion hood that are interlocked, providing an internal area and structure that facilitates easy installation, disassembly, and cleaning. Two inner inlet / outlet pipes are fixedly connected to the first diversion hood; four outer inlet / outlet pipes are fixedly connected to the second diversion hood. A first groove is formed within the first diversion hood, creating a passage between the first groove and the second diversion hood, allowing liquid to pass through. A first limiting cover is fixedly connected within the first groove. An elastic baffle made of silicone is inserted into the first limiting cover. A through hole is formed on the elastic baffle connecting the inner inlet / outlet pipes. Through the elastic baffle and the through hole, one inner inlet / outlet pipe can connect to two outer inlet / outlet pipes, thus achieving two pathways: one for clean water and the other for wastewater, without interference. This allows for continuous liquid circulation for brushing when used in a fully automatic toothbrush.

[0023] The elastic baffle has a clearance groove connecting the outer inlet and outlet pipes. The clearance groove allows the two outer inlet and outlet pipes to connect to the through hole on the elastic baffle, thereby realizing the connection between the inner inlet and outlet pipe and the two outer inlet and outlet pipes. This achieves a flow path that is divided into two or combined into one, which can effectively reduce the discharge velocity of the outer inlet and outlet pipes and prevent the generation of impact pressure that could damage the oral cavity and gums.

[0024] The second flow divider has a second groove corresponding to the first groove. The second groove, in conjunction with the first groove, expands the space of the flow channel, allowing one inner inlet / outlet pipe to connect with two outer inlet / outlet pipes, thus achieving a flow path that is divided into two or combined into one. This effectively reduces the discharge velocity of the outer inlet / outlet pipes, preventing the generation of impact pressure that could damage the oral cavity and gums.

[0025] A second limiting cover is fixed to the elastic baffle in the second groove. The elastic baffle can be stably limited by the second limiting cover in conjunction with the first limiting cover, so that the liquid can pass through smoothly without leakage.

[0026] The inner side of the first diversion shroud is fixed with a foolproof protrusion, which allows the direction of insertion to be distinguished during the insertion process, thereby ensuring the correct connection of the pipe.

[0027] The outer surface of the first distributor has multiple anti-slip protrusions, which increase the friction with the toothbrush, thereby increasing the connection strength and preventing it from coming loose during use.
