In the following description, specific details such as specific configurations and components are provided merely to facilitate a thorough understanding of embodiments of the utility model. It will therefore be apparent to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the utility model. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

Aiming at the defects that the existing electric toothbrush cannot realize multi-toothpaste switching and has poor using effect due to single cleaning mode, the utility model provides the electric toothbrush with multi-toothpaste switching.

Referring to fig. 1 to 3, an embodiment of the present utility model provides a multi-toothpaste switched electric toothbrush, comprising:

a toothbrush head 1;

at least two toothpaste bins 2, each toothpaste bin 2 is respectively communicated to the toothbrush head 1 through a pipeline;

a peristaltic pump 3 in communication with each of said tubes; among the pipelines, a first pipeline 41 of the toothpaste bin communicated with the peristaltic pump and a second pipeline 42 of the peristaltic pump 3 communicated with the toothbrush head are respectively provided with a one-way valve structure 5;

a plurality of solenoid valve assemblies 6, each of said solenoid valve assemblies 6 being disposed on said first conduit 41;

a control circuit (not shown) is electrically connected to each of the solenoid valve assemblies 6 and the peristaltic pump 3, respectively.

In the embodiment of the utility model, one end of the peristaltic pump 3 is communicated with the toothpaste bin 2 through a first pipeline 41, and the other end is communicated with the toothbrush head 1 through a second pipeline 42. In one implementation, the flow direction of the pipeline is: the opening of the solenoid valve assembly 6 (solenoid valve C in figure 1) is controlled, that is, the solenoid valve assembly 6 (solenoid valve C in figure 1) is controlled to be powered on, and the toothpaste in the toothpaste bin (toothpaste bin A in figure 1) is conveyed to the toothbrush head by the operation of a peristaltic pump 3 by utilizing the air pressure in the pipeline. Further, after the electromagnetic valve assembly 6 (electromagnetic valve C in fig. 1) is controlled to be electrified, the peristaltic pump 3 starts to work in a positive rotation mode, negative pressure begins to appear in the cavity of the toothpaste bin A, and the phenomenon of the negative pressure can enable the piston of the toothpaste bin A to move upwards, so that toothpaste in the toothpaste bin A is extruded to be conveyed upwards. Due to the action of the one-way valve structure 5, the toothpaste flows in the direction of the arrow in fig. 1 until reaching the outlet, i.e. the bristle center area of the toothbrush head 1, and after the time for the specified weight of toothpaste is calculated in advance by the control circuit, the control circuit controls the solenoid valve assembly 6 to be powered off.

It should be noted that, the electromagnetic valve assembly 6 after power failure can be supplied with air, because the peristaltic pump 3 is still working, the generated negative pressure can preferentially suck the air entering from the electromagnetic valve assembly 6, but not toothpaste in the toothpaste bin a, after the time from sucking the air to the time when the air reaches the brush head position area is calculated (the step is to fully transmit the residual toothpaste in the pipeline to the toothbrush head 1, so as to avoid mixing two types of toothpaste in the toothpaste bin a and the toothpaste bin B), the peristaltic pump 3 is powered off to stop working.

Because the structure is provided with the one-way valve structure 5, the condition that toothpaste flows backwards in the pipeline can not happen.

In another implementation, the flow direction of the pipeline is: the opening of the solenoid valve assembly 6 (solenoid valve D in FIG. 1) is controlled, and the toothpaste in the toothpaste bin (toothpaste bin B in FIG. 1) is delivered to the toothbrush head by the operation of a peristaltic pump 3 by utilizing the air pressure in the pipeline.

It should be noted that, since the solenoid valve assembly 6 is disposed on the first pipeline, after any solenoid valve assembly 6 is opened, the flow direction of the pipeline is: the toothpaste compartment of the first pipeline, which is communicated with the opened electromagnetic valve assembly 6, flows in the direction of the second pipeline, which is communicated with the first pipeline, wherein the toothpaste compartment inevitably passes through the peristaltic pump.

The technical scheme of the utility model is that the electric toothbrush with multiple toothpaste bins and capable of automatically discharging liquid can store different toothpastes, is suitable for different scenes (such as a scene in the morning and evening, a scene in which diseases occur on gums, and the like), plays the effect of the toothpastes with corresponding efficacy in the applicable scene to the greatest extent, does not need to carry a toothpaste bag alone, achieves the aim of multiple purposes, is free of matching of multiple toothpastes with different efficacy, is flexibly switched, is convenient for daily oral cleaning, nursing and health of a user, and improves the experience of the user.

Optionally, the electric toothbrush further comprises;

a third pipe 43, a plurality of the second pipes 42 are connected to one end of the third pipe 43 in a communicating manner, and the other end of the third pipe 43 is connected to the brush head 1.

In this embodiment, the plurality of second pipes 42 are connected to the third pipe 43 in a converging manner, and the other end of the third pipe 43 is communicated with the brush head 1, so that the arrangement space of the inner pipes of the electric toothbrush can be saved.

It should be noted that, through the negative pressure of the pipeline, the check valve structure 5 and the peristaltic pump 3, all the residual toothpaste in the first pipeline 41, the second pipeline 42 and the third pipeline 43 can be pushed to the toothbrush head 1, so that the residual toothpaste can be prevented from remaining in the third pipeline 43, and when the toothpaste bin 2 is switched, the mixing of different types of toothpaste occurs.

Optionally, the electromagnetic valve assembly 6 is a normally open electromagnetic valve, and the control circuit sends a first pump control signal to the peristaltic pump if the normally open electromagnetic valve is pressed; the first pump control signal is used for indicating the working state of starting the peristaltic pump;

the control circuit sends a second pump control signal to the peristaltic pump with the normally open solenoid valve released; the second pump control signal is used for indicating to stop working after maintaining the working state of the peristaltic pump for a preset period of time.

Here, the solenoid valve assembly 6 is a normally open solenoid valve. Referring to fig. 1, in one implementation, after solenoid valve assembly 6 (solenoid valve C in fig. 1) is energized closed, toothpaste within toothpaste compartment a may pass through communication with solenoid valve assembly 6 (solenoid valve C in fig. 1). In the case where the solenoid valve assembly 6 (solenoid valve C in fig. 1) is pressed, the solenoid valve assembly 6 (solenoid valve C in fig. 1) is energized, and the control circuit sends a first pump control signal to the peristaltic pump 3; the first pump control signal is used for indicating the working state of starting the peristaltic pump 3; after a preset amount of toothpaste is delivered, the electromagnetic valve assembly 6 (the electromagnetic valve C in fig. 1) is powered off, and the control circuit sends a second pump control signal to the peristaltic pump 3; the second pump control signal is used for indicating that the peristaltic pump 3 stops working after maintaining the working state for a preset period of time.

For example, after the solenoid valve assembly 6 (solenoid valve C in fig. 1) is energized to deliver a predetermined amount of toothpaste to the toothbrush head 1, the solenoid valve assembly 6 (solenoid valve C in fig. 1) is de-energized, and the peristaltic pump 3 is operated for several seconds to deliver the toothpaste remaining in the tube to the toothbrush head 1, and then the peristaltic pump 3 is stopped.
