[0003] In recent years, with the increasing awareness of oral health among consumers, the market demand for oral health care products has increased sharply. And the demand content no longer simply stays at the basic cleaning function, but develops towards a more refined and personalized direction, especially in terms of diverse flavors and functions. Some consumers will choose to buy oral care liquid concentrate and mix it with water by themselves to prepare an oral care liquid that meets their personal preferences in terms of flavor and specific functions. However, this approach has many problems, such as the complex and time-consuming preparation process, inaccurate dosage control, difficulty in ensuring hygienic conditions, lack of scientific ingredient combination, etc., making the final prepared product unsatisfactory in terms of taste or cleaning effect.

[0039] Please refer to Figures 1 to 4 , an oral care liquid preparation device provided by an embodiment of the present utility model, includes a liquid storage unit 1 and a power unit 2;

[0040] The liquid storage unit 1 is a container with a piston structure, which is used to store the liquid raw materials for preparing the oral care liquid;

[0041] The first end of the power unit 2 is used to push the piston structure, so that the volume inside the liquid storage unit 1 is reduced, and the liquid raw materials in the liquid storage unit 1 are discharged from the liquid outlet of the liquid storage unit 1;

[0042] A detection element 3 is arranged on the power unit 2, and the detection element 3 is communicatively connected with the power unit 2;

[0043] The detection element 3 is used to detect whether the first end contacts an external object.

[0044] It should be noted that the liquid raw materials for preparing the oral care liquid include a concentrated liquid and a diluent; the concentrated liquid refers to the undiluted liquid raw material for preparing the oral care liquid, which contains the active ingredients of the oral care liquid at a high concentration; the diluent refers to the liquid raw material used to mix with the concentrated liquid to reach the use concentration. Usually, the diluent is water. According to different oral care liquid formulations, it can also be a solvent such as physiological saline or alcohol that is easy to purchase. The liquid storage unit 1 can be used to store the concentrated liquid or the diluent. In the oral care liquid preparation device provided by the present utility model, the number of the liquid storage units 1 can be multiple, and the number of the power units 2 is the same as that of the liquid storage units 1 and corresponds one by one to achieve the quantitative output of multiple liquid raw materials.

[0045] The liquid storage unit 1 is a container with a piston structure that can move linearly or curvilinearly inside the container according to the shape of the internal space of the container; specifically, the liquid storage unit 1 may include a liquid storage body 11 and a piston 12; one end of the liquid storage body 11 is open, and the other end of the liquid storage body 11 is provided with a liquid outlet 13; the liquid storage body 11 is a container with a uniform shape in the moving direction of the piston 12, and the cross-section of its internal space remains the same along the moving direction of the piston 12; the piston 12 is slidably and sealingly arranged inside the first liquid storage body 11; the power unit 2 is used to push the piston 12 from the open end of the liquid storage body 11 to extrude the liquid raw material out of the liquid storage unit 1 from the liquid outlet 13; in the present utility model, the liquid outlet 13 of the liquid storage unit 1 can be connected to the total liquid outlet of the oral care liquid preparation device through a pipeline or other connecting parts, and the connection between the liquid outlet 13 and the pipeline or other connecting parts is a detachable and sealed connection, which is convenient for the user to independently replace the new liquid storage unit 1; the new liquid storage unit refers to a used or unused liquid storage unit that replaces the replaced liquid storage unit.

[0046] Specifically, the power unit 2 may include a slider 21, a driving device 22 and a transmission mechanism 23. The driving device 22 is drivingly connected to the transmission mechanism 23, and the transmission mechanism 23 is drivingly connected to the slider 21; one end of the slider 21 is used to push the piston structure of the liquid storage unit, and the first end is the end where the slider 21 contacts the piston structure. The position where the transmission structure 23 is drivingly connected to the slider 21 can be set at a position close to the other end of the slider 21; the driving device 22 can be a stepping motor, a compression spring or other driving devices; in a specific embodiment, the driving device 22 is a driving device that outputs rotational motion (such as a motor), the transmission mechanism 23 includes a screw 231 and a guide rod 232, the slider 21 is meshed with the screw 231, and the slider 21 is slidably connected to the guide rod 232; the length directions of the screw 231 and the guide rod 232 are the same; the driving device 22 is used to drive the screw 231 to rotate; the slider 21 is used to move along the length direction of the guide rod 232 under the drive of the screw 231.

[0047] The detection element 3 can be a tactile switch, proximity sensor, pressure sensor, etc., and can be set at any position where the contact between the first end and an external object can be detected. Preferably, it is set at the first end of the power unit 2 to ensure the response speed of the detection element to detect the contact between the first end and the piston structure of the liquid storage unit 1. The detection element 3 can be communicatively connected to the power unit 2 through components such as a microcontroller, signal conditioning circuit, and drive circuit.

[0048] In this practical application, when replacing the liquid storage unit 1, after installing a new first liquid storage unit 1, the driving device 22 in the power unit 2 can be started to make the first end start to move towards the liquid storage unit 1. When the detection element 3 detects the contact between the first end and the piston structure of the liquid storage unit 1, the detection element 3 controls the driving device of the power unit 2 to pause, and the first end of the power unit 2 is positioned at the position of the piston structure. At this time, starting the power unit 2 again to make the first end push the piston structure of the liquid storage unit 1 can ensure that the moving distance of the first end is in a proportional relationship with the output amount of the liquid raw material, ensuring the accuracy of the output amount of the liquid raw material.

[0049] In a preferred embodiment, the detection element 3 is a tactile switch.

[0050] It can be understood that a tactile switch is an electronic component used to detect whether there is a physical contact or pressing action. When the first end of the power unit 2 contacts the piston structure of the liquid storage unit 1, the button of the tactile switch is pressed by the piston structure, and after the tactile switch is triggered, it sends a signal to make the driving device 22 of the power unit 2 pause. Specifically, the main body of the tactile switch is embedded in the first end of the power unit 2, and the button of the tactile switch extends from the inside of the first end to the outside of the end face of the first end, avoiding the piston structure from overly pressing the tactile switch and accelerating the fatigue and wear of the tactile switch.

[0051] In a preferred embodiment, the detection element 3 is a pressure sensor.

[0052] It can be understood that when the first end of the power unit 2 contacts the piston structure of the liquid storage unit 1, the pressure sensor can sense the pressure change generated by the contact between the two and send a signal to make the driving device 22 of the power unit 2 pause. Specifically, the pressure sensor can be installed on the end face of the first end of the power unit 2.

[0053] In a preferred embodiment, since both the tactile switch and the pressure sensor rely on physical contact with the piston structure for detection and are prone to fatigue and wear under long-term pressure and have relatively limited service lives, a proximity sensor is used as the detection element 3. The proximity sensor can detect without directly contacting the piston structure itself. Specifically, please refer to Figure 4, a proximity sensor is embedded in the first end of the power unit 2, and its detection signal is emitted towards the piston structure. The emission direction of the detection signal of the proximity sensor is the same as the moving direction of the power unit towards the piston structure.

[0054] The proximity sensor can be a photoelectric proximity sensor, an ultrasonic proximity sensor, etc. After light (visible light, infrared light, etc.) or ultrasonic pulses are emitted from the proximity sensor, they are emitted from the inside of the first end and hit the piston structure. By detecting the intensity of the reflected light received or the round-trip time of the ultrasonic wave, it can be confirmed whether the distance between the piston structure and the proximity sensor is the preset detection distance (the preset detection distance can be set according to the distance between the proximity sensor and the piston structure when the first end contacts the piston structure). If the preset detection distance is satisfied, a signal can be sent to suspend the operation of the driving device 22 of the power unit 2; the setting of the detection distance of the proximity sensor is common knowledge and will not be elaborated in detail in this embodiment.

[0055] In a preferred embodiment, the oral care liquid dispensing device provided by the present invention further includes a control unit; the control unit is communicatively connected to the power unit 2 and the detection element 3 respectively. The control unit is used for monitoring and collecting the working data of the power unit 2 and the detection data of the detection element 3, and for controlling the start and stop of the power unit 2.

[0056] In practical applications, those skilled in the art can perform calculations and control feedback on the data collected by the control unit based on common knowledge. The working data of the power unit 2 includes the number of turns of the driving device 22 rotating, etc. Those skilled in the art can calculate the moving distance of the first end of the power unit 2 according to the working data of the power unit 2 and the transmission parameters, and use the relationship between the moving distance of the first end of the power unit 2 and the output amount of the liquid raw material. Combining the moving distance of the first end when the detection element 3 detects that the first end moves to the position in contact with the piston structure or the real-time moving distance of the first end, the current remaining amount of the liquid raw material in the liquid storage unit 1 can be calculated.

[0057] In the present invention, the setting of the detection element 3 and the control unit can provide a hardware basis for the intelligent processing of the oral care liquid dispensing device. The content related to specific programming to further realize the intelligent function is the method content that those skilled in the art can realize based on common knowledge. The above description of the working process of the detection element 3 and the control unit is only used to illustrate the beneficial effects that can be achieved by the improvement of this hardware structure.

[0058] The above has introduced in detail an oral care liquid dispensing device provided by the present invention. For those of ordinary skill in the art, according to the idea of the embodiments of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
