[0049] An embodiment of the utility model discloses an oral care liquid preparation device, which solves the technical problem of relatively high safety risk of directly using tap water to prepare oral care liquid.

[0050] The technical solution of the utility model will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative work shall fall within the protection scope of the utility model.

[0052] Unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood according to specific situations.

[0053] Please refer to Figures 1 to 6 , an embodiment one of the utility model provides an oral care liquid preparation device, including: a first liquid storage unit 11, a first power unit 12, a second liquid storage unit 13, a second power unit 14, and a liquid mixing unit 15;

[0054] The number of the first liquid storage units 11 is at least one, and the first liquid storage units 11 are used for storing concentrated liquid;

[0055] The number of the first power units 12 is the same as that of the first liquid storage units 11. The first power units 12 are arranged in one-to-one correspondence with the first liquid storage units 11, and the first power units 12 are used to provide power for the output of the concentrated liquid from the first liquid storage units 11;

[0056] The second liquid storage unit 13 is used for storing dilution liquid;

[0057] The second power unit 14 is used to provide power for the output of the diluent from the second liquid storage unit 13 and for the output of the liquid in the liquid mixing unit 15;

[0058] The liquid mixing unit 15 is used to hold the liquids output from the first liquid storage unit 11 and the second liquid storage unit 13;

[0059] The first liquid storage unit 11, the second liquid storage unit 13 and the second power unit 14 are respectively connected to the liquid mixing unit 15;

[0060] The second power unit 14 is provided with a first liquid outlet 141 for communicating with the outside.

[0061] It can be understood that in this embodiment, the first liquid storage unit 11, the second liquid storage unit 13 and the second power unit 14 are connected to the liquid mixing unit 15 through pipelines; 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, and according to different oral care liquid formulas, it can also be physiological saline, alcohol and other solvents that are easy to purchase.

[0062] The first power unit 12 is specifically used to provide power for the output of the concentrated liquid from the first liquid storage unit 11. After the first power unit 12 is started, the concentrated liquid is extruded, pressed or pushed out from the first liquid storage unit 11; a first valve 151 can be provided on the pipeline connecting the first liquid storage unit 11 and the liquid mixing unit 15. The first valve 151 can be opened when the first power unit 12 is working and closed after the first power unit 12 stops working to prevent the concentrated liquid in the first liquid storage unit 11 from being drawn out when the second power unit 14 is working; when the number of the first liquid storage units 11 and the first power units 12 is both N, first valves 151 are provided on the pipelines connecting each first liquid storage unit 11 and the liquid mixing unit 15, and the number of the first valves 151 is also N; the first valve 151 can be a valve of types such as solenoid valve, check valve, duckbill valve, etc.; when the number of the first liquid storage units 11 and the first power units 12 is both two, the two groups of first liquid storage units 11 and first power units 12 can be symmetrically arranged to make the internal layout of the equipment more compact.

[0063] The first liquid storage unit 11 can be a soft or hard container with a uniform shape. A uniform container shape means that the wall thickness of the container remains consistent in each part or changes according to a preset rule, and its cross-section remains the same or changes gently along the height direction according to design requirements, which helps to maintain the consistency of fluid pressure, avoid local overpressure or uneven flow rate, and ensure efficient and stable liquid transmission. Depending on the different shapes, structures, and materials of the first liquid storage unit 11, different first power units 12 can be selected. For example, when using a soft first liquid storage unit 11, the first power unit 12 can adopt an extrusion mechanism with an extrusion structure such as a pressing plate or a roller, which can apply a constant pressure to the container wall of the first liquid storage unit 11 to deform it, so as to extrude the concentrated liquid in the first liquid storage unit 11 at a uniform speed. When using a first liquid storage unit 11 with a piston structure and a uniform shape, the first power unit 12 can adopt a stepper motor, a compression spring, or other driving devices and corresponding transmission mechanisms, which can push the piston of the first liquid storage unit 11 to change the volume of the first liquid storage unit 11, so that the concentrated liquid is discharged from the first liquid storage unit 11, and the quantitative output of the concentrated liquid can be realized by controlling the moving distance of the piston structure.

[0064] A third liquid outlet for communicating with the mixing unit 15 is provided on the first liquid storage unit 11, and the pipeline connecting the first liquid storage unit 11 and the mixing unit 15 is detachably and hermetically connected to the third liquid outlet, which is convenient for users to independently replace the new first liquid storage unit 11.

[0065] The second power unit 14 is specifically used to provide power for the uniform output of the diluent from the second liquid storage unit 13. After the second power unit 14 is started, the amount of diluent output per unit time is the same. The second power unit 14 can be a water pump that can provide a constant flow rate, such as a centrifugal pump or a piston pump. A second valve can be provided on the pipeline connecting the second liquid storage unit 13 and the mixing unit 15. The second valve can be opened when the second power unit 14 is working and closed after the second power unit 14 stops working. Further, the second power unit 14 can be a water pump with a self-locking function. In this case, there is no need to set a second valve. A water pump with a self-locking function refers to a water pump with a mechanical self-locking valve inside. When the water pump does not work, if the inlet pressure is less than the self-locking force of the valve, the valve will automatically cut off the channel between the water pump inlet and outlet. Specifically, the water pump can have a double-sealed structure. When the water pump does not work, when the hydraulic pressure reverses or invades the water pump, the self-locking door plate of the valve will automatically close for sealing following the flow direction of the liquid. A water pump with a self-locking function can also achieve the self-locking function of the water pump through a pressure sensing element. The pressure sensing element controls the opening and closing of the valve inside the water pump by sensing the liquid pressure changes on both sides of the water pump inlet and outlet. The first liquid outlet 141 can be located on the front or below of the device, with the opening facing down.

[0066] The second liquid storage unit 13 may include a second liquid storage body 131 with an open top or a completely open top, and an upper cover 132 covering the open top of the second liquid storage body 131, which facilitates the replenishment or replacement of the diluent; in order to prevent the liquid in the mixing unit 15 from flowing back into the second liquid storage unit 13, the second liquid storage unit 13 may be arranged above the first liquid storage unit 11 and the mixing unit 15; when the diluent in the second liquid storage unit 13 is insufficient, air will enter the pipeline from the liquid outlet of the second liquid storage unit 13, resulting in the idling of the second power unit 14. Therefore, a liquid level detection element for detecting the liquid level in the second liquid storage unit 13, such as a water level gauge, a liquid level sensor, etc., may be arranged in the second liquid storage unit 13.

[0067] The mixing unit 15 may be a hollow cavity, or only a section of pipeline connecting each liquid storage unit and the second power unit 14.

[0068] In this embodiment, by separately controlling the start and stop of the first power unit 12 and the second power unit 14, the concentrated liquid and the diluent are respectively quantitatively transported to the mixing unit for mixing and then output from the first liquid outlet 141 for the user to use, so as to realize the automatic configuration of the oral care liquid according to the precise ratio of the concentrated liquid and the diluent, and improve the quality of the personalized configured oral care liquid.

[0069] In a preferred embodiment, please refer to Figures 7 to 8 , the first liquid storage unit 11 includes a first liquid storage body 111 and a piston 112;

[0070] One end of the first liquid storage body 111 is open, and a third liquid outlet is arranged at the other end of the first liquid storage body 111;

[0071] The piston 112 is slidably arranged in the first liquid storage body 111;

[0072] The first power unit 12 is used to push the piston 112 from the open end of the first liquid storage body 111 to extrude the concentrated liquid from the third liquid outlet out of the first liquid storage unit 11.

[0073] It should be noted that after the piston 112 moves under the action of the first power unit 12, the volume of the inner cavity of the first liquid storage body 111 will change. The first power unit 12 may include a stepping motor, a compression spring or other driving devices and corresponding transmission mechanisms, which can push the piston 112 to perform a linear motion; the first liquid storage unit 11 may be a rigid and uniformly shaped container, such as a container with a cylindrical barrel structure; the concentrated liquid is filled in the first liquid storage body 111. When the first liquid storage body 111 is filled with the concentrated liquid, the piston 112 is at a position close to the open end of the first liquid storage body 111. When the concentrated liquid in the first liquid storage body 111 is used up, the piston 112 moves to a position in contact with the inner wall of the other end of the first liquid storage body 111.

[0074] The piston 112 may include a rigid piston portion, and there is a sliding seal connection between the rigid piston portion and the first liquid storage body 111. The sliding seal connection can be achieved by the close fit between the rigid piston portion and the inner side of the first liquid storage body, or by setting sealing structures such as packing seals, mechanical seals, and labyrinth seals. In a specific embodiment, as Figure 8 shown, the piston 112 includes a soft piston portion 1121 and a rigid piston portion 1122. The soft piston portion 1121 partially or completely wraps around the outside of the rigid piston portion 1122. The soft piston portion 1121 should at least wrap around the position where the piston 112 contacts the inner side of the first liquid storage body 111, so that the sliding contact surface between the soft piston portion 1121 and the inner side of the first liquid storage body 111 can form an effective sealing interface. The rigid piston portion 1122 can be made of materials with a certain hardness, such as hard plastics, cemented carbides, ceramics, etc., which are not specifically limited here. The soft piston portion 1121 is preferably made of an elastic material. Further, multiple annular grooves can be provided along the sliding direction of the piston 112 at the position where the soft piston portion 1121 contacts the inner side of the first liquid storage body 111, which can make the sliding of the piston 112 smoother without affecting the sealing effect.

[0075] When producing the first liquid storage unit 11 provided in this preferred embodiment, in order to minimize the air therein, it is preferred to fill the concentrated liquid from the third liquid outlet. After the concentrated liquid is filled, a sealing cover for sealing the third liquid outlet can be provided. The sealing cover can be removed before using the first liquid storage unit 11, or the third liquid outlet can be sealed by a sealing film made of aluminum paper or composite materials. The sealing film can be torn or punctured before use. Correspondingly, a pointed head capable of puncturing the sealing film at the third liquid outlet can be provided inside the pipe orifice connected to the third liquid outlet in the pipeline connecting the first liquid storage unit 11 and the liquid mixing unit 15.

[0076] In a more preferred embodiment, please refer to Figures 9 to 11 , the first power unit 12 includes a first driving device 121, a transmission mechanism, and a slider 124;

[0077] The first driving device 121 is drivingly connected to the transmission mechanism, and the transmission mechanism is drivingly connected to the slider 124;

[0078] The first driving device 121 is used to drive the transmission mechanism to make the slider 124 perform a linear motion;

[0079] The slider 124 is used to push the piston 112.

[0080] In this preferred embodiment, when the slider 124 moves toward the piston 112, one end can push the piston 112 after contacting with the piston 112, so that the concentrated liquid in the first liquid storage body 111 is discharged, and the position where the slider 124 is connected to the transmission mechanism is close to the other end; the first driving device 121 can be a stepping motor, a compression spring or other driving device. Accordingly, no matter what the motion form of the driving device output is (rotational motion, linear motion, swinging motion, etc.), the transmission mechanism must have the ability to convert it into the linear motion of the slider; when replacing the first liquid storage unit 11, remove After the old first liquid storage unit 11 is replaced, the slider 124 needs to return to the position farthest from the first liquid storage unit and then load the new first liquid storage unit 11; the old first liquid storage unit refers to the first liquid storage unit that needs to be replaced, which is not used up or has been used up, and the new first liquid storage unit refers to the first liquid storage unit that is used or has not been used as a substitute. New and old are not limitations on the usage of the first liquid storage unit. For example, if a first liquid storage unit with a flavor you don't like is replaced with a first liquid storage unit with other flavors, the former is not necessarily completely used up, and the latter is not necessarily brand new.

[0081] In a specific embodiment, the first driving device 121 is a driving device (such as a motor) that outputs rotational motion, and the transmission mechanism may include a screw 122 and a guide rod 123, a slider 124 is meshedly connected to the screw 122, and the slider 124 is slidably connected to the guide rod 123; the length direction of the screw 122 is consistent with that of the guide rod 123; the first driving device 121 is used to drive the screw 122 to rotate; the slider 124 is used to move along the length direction of the guide rod 123 under the drive of the screw 122.

[0082] Furthermore, the first power unit 12 further includes a first detection element 125 for detecting whether the slider 124 moves to a position in contact with the piston 112, and the first detection element 125 can be controllably connected to the first driving device 121. When the first liquid storage unit 11 is replaced, after the new first liquid storage unit 11 is loaded, the slider 124 can start to move toward the first liquid storage unit 11; when the first detection element 125 detects that the slider 124 moves to a position in contact with the piston 112, the slider 124 can stop moving and the first driving device 121 is paused.

[0083] The first detection unit 125 can be set at any position where the contact between the slider and the piston can be detected, preferably at one end of the slider 124 close to the piston 112; the first detection element 125 can be a touch switch, a proximity sensor, a pressure sensor, etc.

[0084] Specifically, if a tactile switch is used as the first detection element 125, when the slider 124 moves to a position in contact with the piston 112, the button of the tactile switch is pressed by the piston. After the tactile switch is triggered, it sends a signal to pause the operation of the first driving device; the main body of the tactile switch can be embedded in one end of the slider 124 close to the piston 112, and the button of the tactile switch extends out of the slider to the end face, avoiding excessive compression of the tactile switch by the piston structure and accelerating the fatigue and wear of the tactile switch.

[0085] If a pressure sensor is used as the first detection element 125, when the slider 124 moves to a position in contact with the piston 112, the pressure sensor can sense the pressure change generated by the contact between the two and send a signal to pause the operation of the first driving device; the pressure sensor can be installed on the end face of one end of the slider 124 close to the piston 112.

[0086] Since both the tactile switch and the pressure sensor rely on physical contact with the piston for detection, they are prone to fatigue and wear under long-term pressure and have a relatively limited lifespan. However, a proximity sensor can perform detection without directly contacting the piston structure. Therefore, a proximity sensor can be used as the first detection element 125. The proximity sensor can be embedded in one end of the slider 124 close to the piston 112, and its detection signal is emitted towards the piston. The emission direction of the detection signal of the proximity sensor is the same as the direction in which the slider moves towards the piston; the proximity sensor can be a photoelectric proximity sensor, an ultrasonic proximity sensor, etc. After light (visible light, infrared light, etc.) or an ultrasonic pulse is emitted from the proximity sensor, it is emitted from within one end of the slider 124 close to the piston 112 and hits the piston. 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 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 when one end of the slider 124 close to the piston 112 contacts the piston). If the preset detection distance is satisfied, a signal can be sent to pause the operation of the first driving device; the setting of the detection distance of the proximity sensor is common knowledge and will not be elaborated in detail in this embodiment.

[0087] If the first detection element 125 still does not detect contact between the slider 124 and an external object when the slider 124 moves to the maximum stroke position towards the first liquid storage unit 11, or if the first detection element 125 only detects contact between the slider 124 and an external object when the slider 124 moves to a preset position (the position when the slider 124 moves to contact the hatch 171 or the housing 17) towards the first liquid storage unit 11, then the first liquid storage unit 11 corresponding to the first power unit 12 is not installed at this time.

[0088] Further, the first power unit 12 further includes a second detection element 126 for detecting whether the slider 124 has moved to the position farthest from the first liquid storage unit 11. The second detection element can be controllably connected to the first driving device 121. When replacing the first liquid storage unit 11, when the second detection element 126 detects that the slider 124 has returned to the position farthest from the first liquid storage unit 11, the slider 124 is reset, and the first driving device 121 can be paused. The second detection element 126 can be a touch switch, a photoelectric sensor, a proximity sensor, a pressure sensor, etc., and can be installed at the position of the end of the slider 124 away from the piston 112 when the slider 124 moves to the position farthest from the first liquid storage unit 11. Figures 9 to 10 in which the slider 124 is located at the position farthest from the first liquid storage unit 11.

[0089] In a preferred embodiment, the oral care liquid configuration device provided by the present utility model further includes a housing 17;

[0090] The housing 17 is used to fix each unit of the oral care liquid configuration device;

[0091] An opening for detaching the first liquid storage unit 11 is formed in the housing 17.

[0092] It can be understood that the housing 17 is used to stably arrange each unit inside it, providing an installation base surface and a support structure for each unit and the components inside the unit, preventing them from being displaced or damaged due to vibration and movement during the operation of the device, and ensuring that each unit and the components inside the unit are kept in the correct positions and maintain appropriate intervals and protection between each other and with the external environment; fixing points, card slots, screw holes, etc. are provided inside the housing 17 to facilitate the orderly arrangement and fixation of each unit and the components inside the unit, which is beneficial to the management and maintenance of the power supply or communication cables inside the device, and also optimizes the space utilization rate; in addition, the body of the second liquid storage unit 13 can be arranged outside the housing 17 in addition to being arranged inside the housing 17, and is detachably connected to the housing 17 to facilitate the cleaning of the inside of the body of the second liquid storage unit 13; the number of openings is the same as and corresponds one by one to the number of the first liquid storage units 11, and the first liquid storage unit 11 can be directly removed from the inside of the oral care liquid configuration device through the opening on the housing 17.

[0093] Further, a hatch 171 is detachably or openably / closably provided at the opening of the housing 17.
