Description

A device for preparing oral care solution Technical Field

[0001] This invention relates to the field of oral hygiene and care technology, and in particular to an oral care solution preparation device. Background Technology

[0002] Oral care solutions (also known as mouthwash, mixed solutions, preparation solutions, etc.) are oral health products mainly used to assist in cleaning the mouth, help remove food debris, reduce oral bacteria and freshen breath. Some types also have the function of preventing oral diseases (such as tooth decay and periodontal disease).

[0003] In recent years, with the increasing awareness of oral health among consumers, the market demand for oral care products has grown rapidly. This demand is no longer limited to basic cleaning but is evolving towards more refined and personalized products, especially in terms of flavor and functional diversity.

[0055] This invention provides an oral care solution preparation device to solve the technical problem of poor quality of manually prepared oral care solutions.

[0056] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; "a plurality of" indicates a quantity of one or more.

[0058] Unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0059] Please refer to Figures 1 to 6. Embodiment 1 of the present invention provides an oral care solution 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 mixing unit 15;

[0060] The number of first liquid storage units 11 is at least one, and the first liquid storage unit 11 is used to store concentrated liquid;

[0061] The number of first power units 12 is the same as the number of first liquid storage units 11. The first power units 12 and the first liquid storage units 11 are arranged in a one-to-one correspondence. The first power units 12 are used to provide power for the concentrated liquid to be output from the first liquid storage unit 11.

[0062] The second liquid storage unit 13 is used to store the diluent;

[0063] The second power unit 14 is used to provide power for the output of diluent from the second liquid storage unit 13, and to provide power for the output of liquid from the mixing unit 15;

[0064] The mixing unit 15 is used to contain the liquids output from the first liquid storage unit 11 and the second liquid storage unit 13;

[0065] The first liquid storage unit 11, the second liquid storage unit 13, and the second power unit 14 are respectively connected to the mixing unit 15;

[0066] The second power unit 14 is provided with a first liquid outlet 141 for communicating with the outside world.

[0067] It is understood that in this embodiment, the first liquid storage unit 11, the second liquid storage unit 13, the second power unit 14, and the mixing unit 15 are connected by pipes; the concentrate refers to the undiluted liquid raw material used to prepare the oral care solution, which contains a high concentration of the effective ingredients of the oral care solution; the diluent refers to the liquid raw material used to mix with the concentrate to achieve the concentration used. The diluent is usually water, but depending on the oral care solution formula, it can also be a readily available solvent such as saline or alcohol.

[0068] The first power unit 12 is specifically used to provide power for the output of the concentrate from the first storage unit 11. After the first power unit 12 is started, it squeezes, presses out, or pushes the concentrate out of the first storage unit 11. A first valve 151 can be installed on the pipeline connecting the first storage unit 11 and the mixing unit 15. The first valve 151 can be opened when the first power unit 12 is working and closed when the first power unit 12 stops working to prevent the second power unit 14 from drawing out the concentrate in the first storage unit 11. When there are N first storage units 11 and N first power units 12, a first valve 151 is installed on the pipeline connecting each first storage unit 11 and the mixing unit 15. The number of first valves 151 is also N. The first valve 151 can be a solenoid valve, a check valve, a duckbill valve, or other types of valve. When there are two first storage units 11 and two first power units 12, the two sets of first storage units 11 and first power units 12 can be symmetrically arranged to make the internal layout of the equipment more compact.

[0069] 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 remains consistent throughout the container or varies according to a preset pattern, and its cross-section remains the same along the height direction or varies gently according to design requirements. This helps maintain consistent fluid pressure, avoids local overpressure or uneven flow, and ensures efficient and stable liquid transfer. Different first power units 12 can be selected to match the different shapes, structures, and materials of the first liquid storage unit 11. For example, when using a soft first liquid storage unit 11, the first power unit 12 can be a container with… The extrusion mechanism, such as a pressure plate or roller, can apply constant pressure to the container wall of the first liquid storage unit 11 to deform it, thereby extruding the concentrate in the first liquid storage unit 11 at a uniform speed. When a first liquid storage unit 11 with a piston structure and uniform shape is used, the first power unit 12 can be a stepper motor, compression spring or other drive device and corresponding transmission mechanism, 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 concentrate is discharged from the first liquid storage unit 11. The quantitative output of the concentrate can be achieved by controlling the movement distance of the piston structure.

[0070] The first liquid storage unit 11 is provided with a third liquid outlet for communicating with the mixing unit 15. The pipe connecting the first liquid storage unit 11 and the mixing unit 15 is detachably sealed to the third liquid outlet, which makes it convenient for users to replace the first liquid storage unit 11 with a new one.

[0071] The second power unit 14 is specifically used to provide power for the uniform output of the diluent from the second 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 centrifugal pump, plunger pump, or other pump that can provide a constant flow rate. A second valve can be installed on the pipeline connecting the second storage unit 13 and the mixing unit 15. The second valve can be opened when the second power unit 14 is working and closed when the second power unit 14 stops working. Furthermore, the second power unit 14 can be a pump with a self-locking function. In this case, a second valve is not required. A pump with a self-locking function refers to... The pump has an internal mechanical self-locking valve. When the pump is not working, if the inlet pressure is less than the valve's self-locking force, the valve will automatically cut off the channel between the pump's inlet and outlet. Specifically, the pump can have a bidirectional sealing structure. When the pump is not working, if hydraulic pressure flows back or enters the pump, the valve's self-locking gate will automatically close and seal in the direction of liquid flow. The self-locking function of the pump can also be achieved through a pressure sensing element. The pressure sensing element controls the opening and closing of the internal valve of the pump by sensing the changes in liquid pressure on both the inlet and outlet sides of the pump. The first outlet 141 can be located on the front or bottom of the equipment, with the opening facing downwards.

[0072] The second liquid storage unit 13 may include a second liquid storage body 131 with a partially or fully open top and a top cover 132 that closes to the open top of the second liquid storage body 131, which facilitates the replenishment or replacement of diluent. To prevent liquid in the mixing unit 15 from flowing back into the second liquid storage unit 13, the second liquid storage unit 13 may be located 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 outlet of the second liquid storage unit 13, causing the second power unit 14 to run idle. Therefore, a liquid level detection element, such as a water level gauge or a liquid level sensor, may be installed in the second liquid storage unit 13 to detect the liquid level in the second liquid storage unit 13.

[0073] The mixing unit 15 can be a hollow cavity, or simply a pipe connecting each liquid storage unit and the second power unit 14.

[0074] In this embodiment, by controlling the start and stop of the first power unit 12 and the second power unit 14 respectively, the concentrate and diluent are quantitatively delivered to the mixing unit for mixing and then output from the first outlet 141 for user use. This enables the automatic preparation of oral care solution according to a precise ratio of concentrate and diluent, thereby improving the quality of personalized oral care solution.

[0075] In a preferred embodiment, referring to Figures 1 to 8, the first liquid storage unit 11 includes a first liquid storage body 111 and a piston 112;

[0076] One end of the first liquid storage body 111 is open, and the other end of the first liquid storage body 111 is provided with a third liquid outlet.

[0077] Piston 112 is slidably disposed within the first liquid storage body 111;

[0078] The first power unit 12 is used to push the piston 112 from the open end of the first liquid storage body 111 to squeeze the concentrated liquid out of the first liquid storage unit 11 from the third liquid outlet.

[0079] It should be noted that after the piston 112 is moved by the first power unit 12, it will change the volume of the inner cavity of the first liquid storage body 111. The first power unit 12 may include a stepper motor, a compression spring or other driving device and a corresponding transmission mechanism, which can drive the piston 112 to perform linear motion. The first liquid storage body 11 can be a rigid and uniformly shaped container, such as a cylindrical container. The concentrate is filled into the first liquid storage body 111. When the first liquid storage body 111 is full of concentrate, the piston 112 is in a position close to the open end of the first liquid storage body 111. When the concentrate in the first liquid storage body 111 is used up, the piston 112 moves to a position that contacts the inner wall of the other end of the first liquid storage body 111.

[0080] Piston 112 may include a rigid piston portion, which is slidably sealed to the first liquid storage body 111. This slidable sealing connection can be achieved by the rigid piston portion tightly fitting against the inner side of the first liquid storage body, or by using a sealing structure such as a packing seal, mechanical seal, or labyrinth seal. In a specific embodiment, as shown in FIG8, piston 112 includes a soft piston portion 1121 and a rigid piston portion 1122, with the soft piston portion 1121 partially or completely enclosing the rigid piston portion 1122. The soft piston portion 1121 should at least enclose the piston 112 and the first liquid storage body 111. The contact position on the inner side of the piston 1121 allows the sliding contact surface between the soft piston part 1121 and the inner side of the first liquid storage body 111 to form an effective sealing interface. The hard piston part 1122 can be made of a material with a certain hardness, such as hard plastic, hard alloy, ceramic, etc., without specific limitation. The soft piston part 1121 is preferably made of an elastic material. Furthermore, the contact position between the soft piston part 1121 and the inner side of the first liquid storage body 111 can be provided with multiple layers of annular grooves along the sliding direction of the piston 112, which can make the sliding of the piston 112 smoother without affecting the sealing effect.

[0081] When producing the first liquid storage unit 11 provided in this preferred embodiment, in order to minimize the air content, it is preferable to fill the concentrate from the third liquid outlet. After the concentrate filling is completed, a sealing cap for sealing the third liquid outlet can be provided. The sealing cap can be removed before using the first liquid storage unit 11, or the third liquid outlet can be sealed with a sealing film made of aluminum foil or composite material. The sealing film can be torn off or punctured before use. Correspondingly, a pointed tip that can puncture the sealing film at the third liquid outlet can be provided in the pipe connecting the first liquid storage unit 11 and the mixing unit 15 to the pipe opening connected to the third liquid outlet.

[0082] In a more preferred embodiment, please refer to Figures 9 to 11, the first power unit 12 includes a first drive device 121, a transmission mechanism, and a slider 124;

[0083] The first driving device 121 is driven by the transmission mechanism, and the transmission mechanism is driven by the slider 124.

[0084] The first driving device 121 is used to drive the slider 124 to perform linear motion through the driving transmission mechanism;

[0085] Slider 124 is used to push piston 112.

[0086] In this preferred embodiment, when the slider 124 moves toward the piston 112, one end can push the piston 112 after contacting it, causing the concentrated liquid in the first liquid storage body 111 to be discharged, while 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 stepper motor, a compression spring, or other driving device. Accordingly, regardless of the motion form output by the driving device (rotational motion, linear motion, oscillating motion, etc.), the transmission mechanism must have the ability to convert it into linear motion of the slider; when replacing the first liquid storage unit 11, the slider is removed. After the old first liquid storage unit 11 is replaced, the slider 124 needs to return to the position furthest from the first liquid storage unit before a new first liquid storage unit 11 is installed. The old first liquid storage unit refers to the first liquid storage unit that needs to be replaced, whether it is unused or used up. The new first liquid storage unit refers to the first liquid storage unit that is used or has never been used as a substitute. The old and new are not limited to the usage of the first liquid storage unit. For example, when replacing the first liquid storage unit containing an undesirable flavor with a first liquid storage unit containing a different flavor, the former is not necessarily completely used up, and the latter is not necessarily brand new.

[0087] In one specific embodiment, the first driving device 121 is a driving device (such as a motor) that outputs rotary motion. The transmission mechanism may include a screw 122 and a guide rod 123. The slider 124 is engaged with the screw 122 and slidably connected to the guide rod 123. The length directions of the screw 122 and the guide rod 123 are the same. 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.

[0088] Furthermore, the first power unit 12 also includes a first detection element 125 for detecting whether the slider 124 has moved to the position of contact with the piston 112. The first detection element 125 can be controlled and connected to the first drive device 121. When replacing the first liquid storage unit 11, after the new first liquid storage unit 11 is installed, the slider 124 can start moving towards the first liquid storage unit 11; when the first detection element 125 detects that the slider 124 has moved to the position of contact with the piston 112, the slider 124 can stop moving, pausing the first drive device 121.

[0089] 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 the end of the slider 124 near the piston 112; the first detection element 125 can be a tactile switch, a proximity sensor, a pressure sensor, etc.

[0090] Specifically, if a tactile switch is used as the first detection element 125, when the slider 124 moves to the position of 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 stop the first drive device from working. The main body of the tactile switch can be embedded in the end of the slider 124 near the piston 112, and the button of the tactile switch extends from inside the slider to the outside of the end face, so as to avoid the piston structure from excessively pressing the tactile switch and accelerating the fatigue and wear of the tactile switch.

[0091] If a pressure sensor is used as the first detection element 125, when the slider 124 moves to the position of 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 stop the first drive device from working; the pressure sensor can be installed on the end face of the slider 124 near the piston 112.

[0092] 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, resulting in a relatively limited lifespan. The proximity sensor, however, can perform detection without direct contact with the piston structure. Therefore, a proximity sensor can be used as the first detection element 125. The proximity sensor can be embedded in the end of the slider 124 near the piston 112, and its detection signal is emitted towards the piston. The direction of the proximity sensor's detection signal emission 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. Light (visible light, infrared light, etc.) or ultrasonic pulses are emitted from the proximity sensor and emitted from the end of the slider 124 near the piston 112, hitting the piston. By detecting the intensity of the received reflected light 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 the end of the slider 124 near the piston 112 is in contact with the piston). If the preset detection distance is met, a signal can be sent to stop the first driving device from operating. The setting of the proximity sensor's detection distance is common knowledge and will not be described in detail in this embodiment.

[0093] If the first detection element 125 fails to detect contact between the slider 124 and a foreign 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 a foreign object when the slider 124 moves to a preset position (the position where the slider 124 contacts the hatch 171 or the shell 17), then the first liquid storage unit 11 corresponding to the first power unit 12 is not installed at this time.

[0094] Furthermore, the first power unit 12 also includes a second detection element 126 for detecting whether the slider 124 has moved to the position furthest from the first liquid storage unit 11. The second detection element can be controlled and connected to the first drive device 121. When the first liquid storage unit 11 is replaced, when the second detection element 126 detects that the slider 124 has returned to the position furthest from the first liquid storage unit 11, the slider 124 completes the reset, and the first drive device 121 can be paused. The second detection element 126 can be a tactile switch, photoelectric sensor, proximity sensor, pressure sensor, etc., and can be installed at the position of the end of the slider 124 furthest from the piston 112 when the slider 124 moves to the position furthest from the first liquid storage unit 11. In Figures 9 and 10, the slider 124 is located at the position furthest from the first liquid storage unit 11.

[0095] In a preferred embodiment, the oral care solution preparation device provided by the present invention further includes a housing 17;

[0096] The housing 17 is used to fix the various units of the oral care solution preparation device; the housing 17 has an opening for disassembling the first liquid storage unit 11.

[0097] Understandably, the housing 17 is used to securely house the various units within it, providing a mounting base and support structure for each unit and its components. This prevents displacement or damage during equipment operation due to vibration or movement, ensuring that each unit and its components remain in the correct position and maintain appropriate spacing and protection between them and the external environment. The housing 17 is equipped with fixing points, slots, screw holes, etc., to facilitate the orderly arrangement and fixing of each unit and its components. This also facilitates the management and maintenance of internal power or communication cables and optimizes space utilization. Furthermore, the body of the second liquid storage unit 13 can be housed not only inside the housing 17 but also outside the housing 17 and can be detachably connected to the housing 17 to facilitate cleaning of the interior of the second liquid storage unit 13. The number of openings corresponds to the number of the first liquid storage units 11, allowing the first liquid storage units 11 to be directly removed from the oral care liquid dispensing device through the openings on the housing 17.

[0098] Furthermore, a detachable or closable hatch 171 is provided at the opening of the housing 17. For example, the hatch 171 is hinged to the housing 17 via a pivot at one side, and a snap-fit ​​structure or magnetic snap is provided at the closing point of the hatch 171 and the housing 17. The hatch 171 can protect the unit components installed inside the housing 17. If there is more than one opening, multiple openings can share one hatch 171 or use different hatches. A third detection element 172 for detecting whether the hatch 171 is open is provided at the connection between the hatch 171 and the housing 17. The third detection element can be controlled and connected to the first drive device 121. When the third detection element 172 detects that the hatch 171 is open, the first power unit 12 can begin to move away from the first liquid storage unit 11, making it easier to remove the first liquid storage unit 11. The third detection element 172 can be a magnetic switch (with a magnet and a magnetic switch installed on the hatch 171 and the housing 17 respectively), a micro switch, a proximity sensor, a limit switch, etc.

[0099] In one specific embodiment, the first liquid storage unit 11 includes a first liquid storage body 111 and a piston 112; one end of the first liquid storage body 111 is open, and the other end of the first liquid storage body 111 is provided with a third liquid outlet; the piston 112 is slidably disposed inside the first liquid storage body 111; the first power unit 12 includes a first driving device 121, a transmission mechanism, a slider 124, a first detection element 125 for detecting whether the slider 124 has moved to a position in contact with the piston 112, and a second detection element 126 for detecting whether the slider has moved to the position furthest from the first liquid storage unit 11; the first driving device 121 is drivenly connected to the transmission mechanism, and the transmission mechanism is drivenly connected to the slider 124; the first driving device 121 is used to drive the slider 124 to perform linear motion by driving the transmission mechanism; the slider 124 is used to push the piston 112; a hatch 171 is detachably or openably disposed at the opening of the housing 17, and a third detection element 172 is disposed at the connection between the hatch 171 and the housing 17 for detecting whether the hatch 171 is open. In this specific embodiment, when the third detection element 172 detects that the hatch 17 is open, the first drive device 121 is activated to make the slider 124 start to move away from the piston 112; when the second detection element 126 detects that the slider 124 has moved to the position furthest from the first liquid storage unit 11, the first drive device 121 is paused; when the third detection element 172 detects that the hatch 171 is closed, the first drive device 121 is activated to make the slider 124 start to move towards the piston 112; when the first detection element 125 detects that the slider 124 has moved to the position of contacting the piston 112, the first drive device 121 is paused.

[0100] The opening on the shell 17 can be specifically located on the side or top of the shell 17. In a specific embodiment, referring to Figures 2 to 8, the opening and hatch 171 are located on the top of the shell 17. A space for accommodating the first liquid storage unit 11 is formed inside the shell 17 below the opening. The first liquid storage unit 11 includes a first liquid storage body 111 and a piston 112. One end of the first liquid storage body 111 is open, and the other end of the first liquid storage body 111 is provided with a third liquid outlet. The piston 112 is slidably disposed inside the first liquid storage body 111. The first power unit 12 is disposed below the first liquid storage body 111. The first power unit 12 includes a first drive... The device includes a drive unit 121, a transmission mechanism, and a slider 124. The first drive unit 121 is driven by the transmission mechanism, which is in turn driven by the slider 124. The first drive unit 121 drives the transmission mechanism to make the slider 124 move linearly, and the slider 124 pushes the piston 112. To allow the first liquid storage unit 11 to be directly pushed in from the open port for installation and to be directly connected to the mixing unit 15 during installation, the open end of the first liquid storage body 111 must be pushed into the open port first. A liquid outlet elbow 113 is sealed at the third liquid outlet, and the liquid outlet elbow 113 is pushed towards the first liquid storage unit 11. The installation direction of the open port is bent, and the pipe connecting the first liquid storage unit 11 and the mixing unit 15 to the third liquid outlet faces the open port. The pipe connecting the first liquid storage unit 11 and the mixing unit 15 and the liquid outlet elbow 113 are detachably and sealed after installation. Specifically, this can be achieved by installing a rubber valve 153 or other sealing device in the pipe connecting the first liquid storage unit 11 and the mixing unit 15 to the liquid outlet elbow. In order to place the second liquid storage unit 13 above the first liquid storage unit 11 and the mixing unit 15, the second liquid storage unit 13 is detachably installed on the top of the housing 17. Therefore, the hatch 171 The upper part has holes for the pipe connecting the second liquid storage unit 13 and the mixing unit 15 to pass through; the first liquid storage body 111 may be provided with a component to assist in removing the first liquid storage unit 11 at one end near the third liquid outlet, such as a handle 114 or a handle that is integrally formed or assembled separately; in this specific embodiment, although the second liquid storage unit 13 needs to be removed before opening the hatch 171 to replace the first liquid storage unit 11, since the sliding direction of the slider 124 is the same as the direction of installation and removal of the first liquid storage unit 11, the old first liquid storage unit 11 can be taken out directly by opening the hatch 171 without waiting for the slider of the first power unit 12 to go down to the lowest position.The third liquid outlet and the liquid outlet elbow 113 can be sealed together by an elastic gasket or other sealing element. A rotating element can be installed at the connection between the third liquid outlet and the liquid outlet elbow 113. The rotating element is designed with a through hole and a partition structure. The through hole or partition structure in the rotating element can rotate a certain angle along the axis of the third liquid outlet with the liquid outlet elbow 113. When the third liquid outlet and the liquid outlet elbow 113 are at a certain preset rotation position, the through hole is aligned and the third liquid outlet and the liquid outlet elbow 113 are connected. When rotated to another preset rotation position, the partition structure will intervene to make the third liquid outlet and the liquid outlet elbow 113 disconnected, so that the unused first liquid storage unit 11 can be restored to a sealed state by rotating the liquid outlet elbow 113 after removal.

[0101] In another specific embodiment, referring to Figures 13 to 17, an opening and a hatch 171 are provided on the side of the housing 17. A space 176 is formed inside the housing 17, directly opposite the opening, to accommodate a first liquid storage unit 11. The first liquid storage unit 11 includes a first liquid storage body 111 and a piston 112. One end of the first liquid storage body 111 is open, and a third liquid outlet 116 is provided on the side of the other end of the first liquid storage body 111. The piston 112 is slidably disposed within the first liquid storage body 111. A first power unit 12 is disposed above the first liquid storage body 111. The first power unit 12 includes a first drive device 121, a transmission mechanism, and a slider 124. The first driving device 121 is driven and connected to the transmission mechanism, which is then connected to the slider 124. The first driving device 121 drives the slider 124 to move linearly through the transmission mechanism, and the slider 124 pushes the piston 112. To allow the first liquid storage unit 11 to be directly pushed in from the open port for installation and to be directly connected to the mixing unit 15 during installation, as shown in Figure 18, the orientation of the third outlet is the same as the installation direction of the first liquid storage unit pushed into the open port. The pipe connecting the first liquid storage unit 11 and the mixing unit 15, with the pipe end connected to the third outlet 116, faces the open port. When installing the first liquid storage unit 11, the third outlet 116 must be aligned with the open port. Insert the pipe directly into the inlet. The pipe connecting the first liquid storage unit 11 and the mixing unit 15 to the third liquid outlet 116 is detachably and sealed after installation. This can be achieved by installing a rubber valve 115 or other sealing device in the pipe connecting the first liquid storage unit 11 and the mixing unit 15 to the inlet of the pipe connecting to the third liquid outlet 116. The side of the first liquid storage body 111 may have an auxiliary component to help remove it, such as a piece of paper partially pasted to the side of the first liquid storage body 111. Pulling the unpainted part of the paper helps remove the first liquid storage body 111. Product information may also be printed on the paper. The edge of the open port may have... Remove the auxiliary space, such as the groove at the edge of the open opening, to facilitate the user to remove the first liquid storage body 111. In this specific embodiment, the second liquid storage unit 13 does not need to be disassembled before opening the hatch 171 to replace the first liquid storage unit 11, but the first liquid storage unit 11 can only be removed when the slider of the first power unit 12 moves back to the position furthest from the first liquid storage unit 11. Since the hatch is not located on the top of the housing 17, the top of the housing 17 can be open and directly connected to the bottom of the second liquid storage unit 13. A sealing ring or other sealing element can be provided at the connection between the top of the housing 17 and the second liquid storage unit 13 to prevent liquid from entering the housing from the connection.

[0102] In a preferred embodiment, tap water is usually used as the diluent to facilitate the acquisition of the diluent. However, tap water may contain minute impurities and / or microorganisms, which pose certain safety risks. Therefore, the oral care solution preparation device provided by the present invention also includes a filter unit 18.

[0103] The bottom of the second liquid storage unit 13 is provided with a second liquid outlet for communicating with the mixing unit 15; the filter unit 18 is provided at the second liquid outlet of the second liquid storage unit 13, or in the pipe connecting the second liquid storage unit 13 and the mixing unit 15.

[0104] It is understandable that a spring stop valve 183 can be installed at the second liquid outlet, and a valve opening mechanism 184 for opening the spring stop valve 183 can be installed at the pipe opening of the pipe connecting the second liquid storage unit 13 and the mixing unit 15. The diluent in the second liquid storage unit 13 will be filtered by the filter unit 18 before entering the mixing unit 15. The filter unit 18 includes filter media and a support structure for fixing the filter media.

[0105] The filter unit 18 can be disposed within the second liquid storage unit 13. Specifically, the filter unit 18 may include a filter element 181 and a filter element housing 182. The filter element 181 is disposed at the second liquid outlet of the second liquid storage unit 13, and the filter element housing 182 is disposed outside the filter element 181 and detachably connected to the bottom of the second liquid storage unit 13. A handle 1823 may be installed on or integrally formed on the top of the filter element housing 182 to facilitate user removal of the filter element housing 182. More specifically, the filter element housing 182 can be fixedly connected to the inner wall of the bottom of the second liquid storage unit 13 by a rotating lock. A locking block 1821 is provided at the lower end of the filter element housing 182, and a locking groove 133 adapted to the locking block 1821 is provided on the inner wall of the bottom of the second liquid storage unit 13. This fixed connection method facilitates disassembly and replacement of the filter element. Filter element 181; Filter element 181 can be a filter element with antibacterial and / or bactericidal functions, such as a silver ion implanted filter element, an ultrafiltration membrane filter element, etc.; further, filter element 181 can be an annular columnar shape, leaving an installation position for the spring stop valve. After the filter element housing 182 is connected to the inner wall of the bottom of the second liquid storage unit 13, the inner top surface of the filter element housing 182 can seal the hole at the upper end of the filter element 181; a filter element bottom cover 185 is installed at the bottom of the filter element 181. The filter element bottom cover 185 is an annular shape that fits the bottom of the filter element 181. After long-term use, the filter element 181 may become loose or partially fall off due to the accumulation of internal impurities. The filter element bottom cover 185 can provide certain support for the filter element by cooperating with the bottom structure of the filter element, so that the filter element can maintain a certain integrity when it is removed by the user.

[0106] The filter housing 182 should allow liquid from the second liquid storage unit to enter it. In one specific embodiment, as shown in FIG12, a water leakage hole is provided on the side of the filter housing 182, through which liquid from the second liquid storage unit can enter the filter housing 182. In another specific embodiment, as shown in FIG17 and FIG19, no water leakage hole is provided on the side of the filter housing 182, and a gap is left at the detachable connection between the filter housing 182 and the bottom of the second liquid storage unit 13, or a water leakage space 1822 is provided at the lower end of the filter housing 182. The arrow in FIG17 is a schematic diagram of the path of liquid from the second liquid storage unit 13 entering the filter unit and flowing to the second outlet in this specific embodiment. Liquid from the second liquid storage unit 13 can enter the filter housing 182 from the gap or the water leakage space, fill the space between the filter housing 182 and the filter element 181, and then enter from the side of the filter element 181 and flow to the second outlet, thus preventing air from entering the filter element in advance.

[0107] In a preferred embodiment, the bottom or side of the housing 17 may be provided with a magnetic element that can attract a mouthwash container made of a ferromagnetic or ferrimagnetic material.

[0108] In a preferred embodiment, as shown in FIG13, a wall-mounting plate 173 is provided on the side of the housing 17, and the wall-mounting plate 173 has mounting holes, through which the oral care liquid dispensing device can be fixed to the wall; further, as shown in FIG14 and FIG15, the area of ​​the wall-mounting plate 173 can be wider than the side of the housing 17 to which it is fixedly connected, and magnetic elements can be provided on the wider part, so that the mouthwash container 175 made of ferromagnetic or ferrimagnetic material can be attracted to it.

[0109] In a preferred embodiment, a vertical support is provided on the outside of the housing 17, which can be used to stand the oral care liquid preparation device provided by the present invention on a table.

[0110] In a preferred embodiment, the oral care solution preparation device provided by the present invention further includes a control unit 16 for controlling the working state of each electrically powered component of the oral care solution preparation device.

[0111] The control unit 16 can communicate with each energized component. The energized components of the oral care solution preparation device include, but are not limited to, the first power unit 13, the second power unit 14, the first valve 151, the second valve, the display unit, the detection unit, the interaction unit, the control unit 16, each detection element, and the power supply unit. The control unit 16 is specifically used to acquire detection data from the detection unit and each detection element, to acquire data such as the working status of the first power unit 12 and the second power unit 14 and the real-time position of the drive component, to process the acquired data, to send the processed data to the display unit, to acquire the remaining power of the power supply unit, and to control the start and stop of each power unit and the opening and closing of each valve. Specifically, the control unit 16 can calculate the current remaining amount of the first storage unit 11 based on the pre-set relationship between the moving distance of the slider of the first power unit 12 and the output volume of the concentrate, combined with the moving distance of the slider of the first power unit 12 when the slider 124 moves to the position of contacting the piston 112 detected by the first detection element 125, or the real-time moving distance of the slider, and send it to the display unit for display; the control unit can send a warning message when the current remaining amount of the first storage unit 11 is less than the preset amount, and when the water level of the second storage unit 13 is lower than the preset water level. The control unit sends an alarm command to the display unit and an alarm command to the sound alert unit. If the first detection element 125 does not detect contact between the slider 124 and a foreign object when the slider 124 moves to the maximum stroke position of the first liquid storage unit 11, or if the first detection element 125 only detects contact between the slider 124 and a foreign object when the slider 124 moves to the preset position (the position where the slider 124 contacts the hatch or shell), then the control unit can determine that the first liquid storage unit 11 corresponding to the first power unit 12 is not installed and sends the command to the display unit for display. When the control unit 16 receives interactive data from the interactive unit, it can control the start and stop of each power unit and the opening and closing of each valve to enable the device to enter different working modes. The working modes may include liquid preparation mode, pipeline flushing mode, etc. When the oral care liquid preparation device provided by the present invention is not in any working mode, each valve is closed and each power unit is paused. When the user selects the pipeline flushing mode through the interactive unit, the control unit controls the second valve to open and the second power unit to start. The diluent in the second storage unit can flush the mixing unit and the pipeline currently connected to the mixing unit, cleaning up any concentrate that may have been left over from the previous liquid preparation. When the user selects the liquid preparation mode through the interactive unit and sets or selects the liquid preparation parameters (such as selecting a certain flavor, which corresponds to the specific concentration and concentrate formula built into the control unit), the control unit can start the second power unit according to the liquid preparation parameters and sequentially start the first power unit corresponding to the required concentrate, respectively, to quantitatively deliver the diluent and the required concentrate to the mixing unit. The starting order is not specifically limited. The control unit can control the power unit to pause after each power unit has delivered the amount corresponding to the liquid preparation parameters.

[0112] Furthermore, contact or non-contact information transmission tags containing different information can be set on the outside of the first liquid storage unit 11 with different flavors. Correspondingly, an identification device for reading the content of the information transmission tag can be set next to the first liquid storage unit 11. The identification device sends the read data to the control unit. The control unit can identify the flavor information of the first liquid storage unit 11 and send it to the display unit for display.

[0113] In a preferred embodiment, the oral care solution preparation device provided by the present invention further includes a display unit for displaying the working information of the oral care solution preparation device. Specifically, the display unit can be a display screen 174 disposed outside the housing 17. The display screen 174 can communicate with each powered component to directly obtain their data, or communicate with the control unit 16 to receive data processed by the control unit, displaying information such as the device's working mode, remaining power of the power supply unit, remaining capacity of each first liquid storage unit 11, and interactive content. When the display screen 174 is a touchscreen, the user can directly interact with the display screen. At point 174, the operating mode and liquid preparation parameters can be selected. When the opening and door 171 are located on the side of the housing 17, as shown in Figure 15, the display screen 174 can be placed on the housing 17 covered by the door 171. At this time, the door 171 can be made of a light-transmitting mirror. When the display screen 174 displays information, light can penetrate the door 171, and the user can see the information on the display screen clearly. The door not only protects the display screen 174 from external physical damage, but also, when the display screen 174 is not working, the light-transmitting mirror door looks like an ordinary mirror, which can improve the overall aesthetics of the equipment.

[0114] In a preferred embodiment, the oral care liquid dispensing device provided by the present invention further includes a detection unit for detecting whether an object is approaching. The detection unit may specifically include an infrared distance sensor disposed on the front of the device. When the device is not in use, the display unit may remain in a screen-off state or only display a small amount of information, including the remaining battery level, in a screen saver state. When an object is detected by the infrared distance sensor within a preset range, the infrared distance sensor sends a wake-up command to the display unit, or sends it to the control unit and then to the display unit, so that the display unit enters a normal display state. When no object is detected by the infrared distance sensor within a preset range within a preset time, it can be confirmed that the device is not in use. The infrared distance sensor may send a sleep command to the display unit, or send it to the control unit and then to the display unit, so that the display unit enters a screen-off state or a screen saver state.

[0115] In a preferred embodiment, the oral care solution preparation device provided by the present invention further includes an interaction unit for enabling interaction between the user and the oral care solution preparation device. The interaction unit can be multiple buttons located on the front of the device; in a specific embodiment, the interaction unit includes three buttons located on the front of the device housing 17, each button having a backlight, and the button functions can be: dispensing, mode selection, and flavor selection, respectively.

[0116] In a preferred embodiment, the oral care solution preparation device provided by the present invention further includes a power supply unit; the power supply unit includes a battery 19 and a charging port, preferably a 5V Type-C interface charging port; the power supply unit is used to provide power to each energized component of the oral care solution preparation device, and the battery 19 can be connected to each energized component to provide power.

[0117] In a preferred embodiment, the oral care solution preparation device provided by the present invention further includes a sound reminder unit for providing audio reminders of interactive information or the operation information of the oral care solution preparation device. Specifically, the sound reminder unit can be communicatively connected to each powered component to directly obtain their data, or communicatively connected to the control unit 16 to receive data processed by the control unit. The sound reminder unit can be a buzzer or a voice module, and can play the key tones of the interactive unit and reminders such as insufficient battery, insufficient concentrate, and insufficient diluent.

[0118] Please refer to Figure 20. Embodiment 2 of the present invention provides an oral care solution preparation device, including: a first liquid storage unit 21, a first power unit 22, a second liquid storage unit 23, a second power unit 24, and a mixing unit 25; the number of first liquid storage units 21 is at least one, and the first liquid storage unit 21 is used to store concentrated liquid; the number of first power units 22 is the same as the number of first liquid storage units 21, and the first power units 22 are arranged in a one-to-one correspondence with the first liquid storage units 21, and the first power units 22 are used to provide power for the concentrated liquid to be output from the first liquid storage unit 21; the second liquid storage unit 23 is used to store diluent; the second power unit 24 is connected to the second liquid storage unit 23, and the second power unit 24 is used to provide power for the diluent to be output from the second liquid storage unit 23; the mixing unit 25 is used to contain the liquid output from the first liquid storage unit 21 and the second liquid storage unit 23; the first liquid storage unit 21 and the second power unit 24 are respectively connected to the mixing unit 25; the mixing unit 25 is provided with a fourth liquid outlet for communication with the outside.

[0119] It is understood that in this embodiment, the second power unit 24 and the second liquid storage unit 23, and the first liquid storage unit 21 and the second power unit 24 and the mixing unit 25 are connected by pipes; the concentrate refers to the undiluted liquid raw material used to prepare the oral care solution, which contains a high concentration of the effective ingredients of the oral care solution; the diluent refers to the liquid raw material used to mix with the concentrate to achieve the concentration used. The diluent is usually water, but depending on the oral care solution formula, it can also be a readily available solvent such as saline or alcohol.

[0120] The first power unit 22 is specifically used to provide power for the output of the concentrate from the first storage unit 21. After the first power unit 22 is started, the concentrate is squeezed out, pressed out, or pushed out from the first storage unit 21. A first valve 251 can be installed on the pipeline connecting the first storage unit 21 and the mixing unit 25. The first valve 251 can be opened when the first power unit 22 is working and closed when the first power unit 22 stops working to prevent the concentrate in the first storage unit 21 from being extracted when the second power unit 24 is working. When there are N first storage units 21 and N first power units 22, a first valve 251 is installed on the pipeline connecting each first storage unit 21 and the mixing unit 25. The number of first valves 251 is also N. The first valve 251 can be a solenoid valve, a check valve, a duckbill valve, or other types of valve.

[0121] The first liquid storage unit 21 can be a soft or hard container with a uniform shape. A uniform container shape means that the wall thickness remains consistent throughout the container or varies according to a preset pattern, and its cross-section remains the same along the height direction or varies gently according to design requirements. This helps maintain consistent fluid pressure, avoids local overpressure or uneven flow, and ensures efficient and stable liquid transfer. Different first power units 22 can be selected to match the first liquid storage unit 21 with different shapes, structures, and materials. For example, when using a soft first liquid storage unit 21, the first power unit 22 can be a container with… The extrusion mechanism, such as a pressure plate or roller, can apply constant pressure to the container wall of the first liquid storage unit 21 to deform it, thereby extruding the concentrate in the first liquid storage unit 21 at a uniform speed. When a first liquid storage unit 21 with a piston structure and uniform shape is used, the first power unit 22 can be a stepper motor, compression spring or other drive device and corresponding transmission mechanism, which can push the piston of the first liquid storage unit 21 to change the volume of the first liquid storage unit 21, so that the concentrate is discharged from the first liquid storage unit 21. The quantitative output of the concentrate can be achieved by controlling the movement distance of the piston structure.

[0122] The first liquid storage unit 21 is provided with a third liquid outlet for communicating with the mixing unit 25. The pipe connecting the first liquid storage unit 21 and the mixing unit 25 is detachably sealed to the third liquid outlet, which makes it convenient for users to replace the first liquid storage unit 21 themselves.

[0123] The second power unit 24 is specifically used to provide power for the uniform output of the diluent from the second storage unit 23. After the second power unit 24 is started, the amount of diluent output per unit time is the same. The second power unit 24 can be a centrifugal pump, plunger pump, or other pump that can provide a constant flow rate. A second valve can be installed on the pipeline connecting the second storage unit 23 and the second power unit 24, or between the second power unit 24 and the mixing unit 25. The second valve can be opened before the second power unit 24 starts working and closed after the second power unit 24 stops working. Furthermore, the second power unit 24 can be a pump with a self-locking function. At this point, a second valve is not required. A water pump with a self-locking function refers to a water pump with an internal mechanical self-locking valve. When the water pump is not working, if the inlet water pressure is less than the valve's self-locking force, the valve will automatically cut off the channel between the water pump inlet and outlet. Specifically, the water pump can have a bidirectional sealing structure. When the water pump is not working, if hydraulic pressure flows back or enters the water pump, the valve's self-locking gate will automatically close and seal in the direction of liquid flow. A water pump with a self-locking function can also achieve the self-locking function through a pressure sensing element. The pressure sensing element controls the opening and closing of the internal valve of the water pump by sensing the changes in liquid pressure on both the inlet and outlet sides of the water pump.

[0124] The second liquid storage unit 23 may include a second liquid storage body with a partially or fully open top and a top cover that closes to the open top of the second liquid storage body, which facilitates the replenishment or replacement of diluent. To prevent liquid in the mixing unit 25 from flowing back into the second liquid storage unit 23, the second liquid storage unit 23 may be located above the first liquid storage unit 21 and the mixing unit 25. When the diluent in the second liquid storage unit 23 is insufficient, air will enter the pipeline from the outlet of the second liquid storage unit 23, causing the second power unit 24 to run idle. Therefore, a liquid level detection element, such as a water level gauge or a liquid level sensor, may be installed in the second liquid storage unit 23 to detect the liquid level in the second liquid storage unit 23.

[0125] The mixing unit 25 can be a hollow cavity, or simply a pipe connecting each of the first liquid storage units and the second power unit 24; the fourth liquid outlet can be located on the front or bottom of the equipment, with the opening facing downwards.

[0126] In this embodiment, by controlling the start and stop of the first power unit 22 and the second power unit 24 respectively, the concentrate and diluent are quantitatively delivered to the mixing unit 25 for mixing and then output from the fourth outlet for user use. This enables the automatic preparation of oral care solution according to a precise ratio of concentrate and diluent, thereby improving the quality of personalized oral care solution.

[0127] In a preferred embodiment, the first liquid storage unit 21 includes a first liquid storage body and a piston; one end of the first liquid storage body is open, and the other end of the first liquid storage body is provided with a third liquid outlet; the piston is slidably disposed in the first liquid storage body; the first power unit is used to push the piston from the open end of the first liquid storage body to squeeze the concentrate out of the first liquid storage unit from the third liquid outlet.

[0128] It should be noted that after the piston is moved by the first power unit 22, it will change the volume of the inner cavity of the first liquid storage body. The first power unit 22 may include a stepper motor, a compression spring or other driving device and a corresponding transmission mechanism, which can drive the piston to perform linear motion. The first liquid storage unit 21 can be a rigid and uniformly shaped container, such as a cylindrical container. The concentrate is filled into the first liquid storage body. When the first liquid storage body is full of concentrate, the piston is in a position close to the open end of the first liquid storage body. When the concentrate in the first liquid storage body is used up, the piston moves to a position that contacts the inner wall of the other end of the first liquid storage body.

[0129] The piston may include a hard piston portion, which is slidably sealed to the first liquid reservoir body. This slidable sealing connection can be achieved by the hard piston portion tightly fitting against the inner side of the first liquid reservoir body, or by using sealing structures such as packing seals, mechanical seals, or labyrinth seals. In one specific embodiment, the piston includes a soft piston portion and a hard piston portion, with the soft piston portion partially or completely enclosing the hard piston portion. The soft piston portion should at least cover the area where the piston contacts the inner side of the first liquid reservoir body, ensuring that the sliding contact surface between the soft piston portion and the inner side of the first liquid reservoir body forms an effective sealing interface. The hard piston portion can be made of a material with a certain hardness, such as hard plastic, hard alloy, or ceramic, without specific limitations. The soft piston portion is preferably made of an elastic material. Furthermore, the area where the soft piston portion contacts the inner side of the first liquid reservoir body can be provided with multiple layers of annular grooves along the piston sliding direction, allowing for smoother piston sliding without affecting the sealing effect.

[0130] When producing the first liquid storage unit 21 provided in this preferred embodiment, in order to minimize the air content, it is preferable to fill the concentrate from the third liquid outlet. After the concentrate filling is completed, a sealing cap can be provided. The sealing cap can be removed before using the first liquid storage unit 21, or the third liquid outlet can be sealed with a sealing film made of aluminum foil or composite material. The sealing film can be torn off or punctured before use. Correspondingly, a pointed tip that can puncture the sealing film at the third liquid outlet can be provided in the pipe connecting the first liquid storage unit 21 and the mixing unit 25 to the pipe opening connected to the third liquid outlet.

[0131] In a more preferred embodiment, the first power unit 22 includes a first driving device, a transmission mechanism, and a slider; the first driving device is drivenly connected to the transmission mechanism, and the transmission mechanism is drivenly connected to the slider; the first driving device is used to drive the transmission mechanism to make the slider move linearly; the slider is used to push the piston.

[0132] In this preferred embodiment, when the slider moves toward the piston, one end can push the piston after contacting it, causing the concentrated liquid in the first liquid storage body to be discharged, while the position where the slider is connected to the transmission mechanism is close to the other end; the first driving device can be a stepper motor, a compression spring, or other driving device. Accordingly, regardless of the motion form output by the driving device (rotational motion, linear motion, oscillating motion, etc.), the transmission mechanism must have the ability to convert it into linear motion of the slider; when replacing the first liquid storage unit 21, after removing the old first liquid storage unit 21, the slider needs to return to the position furthest from the first liquid storage unit 21 before inserting the new first liquid storage unit 21; the old first liquid storage unit 21 refers to the first liquid storage unit 21 that needs to be replaced, which is either unused or used up, and the new first liquid storage unit 21 refers to the first liquid storage unit 21 that is used as a substitute, which may or may not have been used. The old and new are not limited to the usage of the first liquid storage unit 21. For example, when replacing the first liquid storage unit 21 containing an undesirable flavor with a first liquid storage unit 21 containing another flavor, the former is not necessarily completely used up, and the latter is not necessarily brand new.

[0133] In one specific embodiment, the first driving device is a driving device that outputs rotary motion (such as a motor), and the transmission mechanism may include a screw and a guide rod. The slider is engaged with the screw and slidably connected to the guide rod. The length directions of the screw and the guide rod are consistent. The first driving device is used to drive the screw to rotate. The slider is used to move along the length direction of the guide rod under the drive of the screw.

[0134] Furthermore, the first power unit 22 also includes a first detection element for detecting whether the slider has moved to the position of contact with the piston. The first detection element can be controlled and connected to the first drive device. When replacing the first liquid storage unit 21, after the new first liquid storage unit 21 is installed, the slider can start moving towards the first liquid storage unit 21; when the first detection element detects that the slider has moved to the position of contact with the piston, the slider can stop moving and pause the first drive device.

[0135] The first detection unit can be set at any position where the contact between the slider and the piston can be detected, preferably at the end of the slider closer to the piston; the first detection element can be a tactile switch, a proximity sensor, a pressure sensor, etc.

[0136] Specifically, if a tactile switch is used as the first detection element, when the slider moves to the position of contact with the piston, the button of the tactile switch is pressed by the piston. After the tactile switch is triggered, it sends a signal to stop the first drive device from working. The main body of the tactile switch can be embedded in the end of the slider near the piston, and the button of the tactile switch extends from inside the slider to the outside of the end face, so as to avoid excessive pressure on the tactile switch by the piston structure and accelerate the fatigue and wear of the tactile switch.

[0137] If a pressure sensor is used as the first detection element, when the slider moves to the position of contact with the piston, the pressure sensor can sense the pressure change generated by the contact between the two and send a signal to stop the first drive device from working; the pressure sensor can be installed on the end face of the slider near the piston.

[0138] Since both tactile switches and pressure sensors rely on physical contact with the piston for detection, they are prone to fatigue and wear under prolonged pressure, resulting in a relatively limited lifespan. Proximity sensors, however, can detect without direct contact with the piston structure. Therefore, a proximity sensor can be used as the first detection element. The proximity sensor can be embedded in the end of the slider near the piston, and its detection signal is emitted towards the piston. The direction of the proximity sensor's signal emission is the same as the direction the slider moves towards the piston. The proximity sensor can be a photoelectric proximity sensor, an ultrasonic proximity sensor, etc. Light (visible light, infrared light, etc.) or ultrasonic pulses are emitted from the proximity sensor and emitted from the end of the slider near the piston, striking the piston. By detecting the intensity of the received reflected light 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 based on the distance between the proximity sensor and the piston when the end of the slider near the piston is in contact with the piston). If the preset detection distance is met, a signal can be sent to stop the first driving device from operating. The setting of the proximity sensor's detection distance is common knowledge and will not be described in detail in this embodiment.

[0139] If the first detection element does not detect contact between the slider and the foreign object when the slider moves to the maximum stroke position of the first liquid storage unit 21, or if the first detection element only detects contact between the slider and the foreign object when the slider moves to the preset position (the position where the slider contacts the hatch or shell), then the first liquid storage unit 21 corresponding to the first power unit 22 is not installed at this time.

[0140] Furthermore, the first power unit 22 also includes a second detection element for detecting whether the slider has moved to the position furthest from the first liquid storage unit 21. The second detection element can be controlled and connected to the first drive device. When the first liquid storage unit 21 is replaced, when the second detection element detects that the slider has returned to the position furthest from the first liquid storage unit 21, the slider completes the reset, and the first drive device can be paused. The second detection element can be a tactile switch, photoelectric sensor, proximity sensor, pressure sensor, etc., and can be installed at the position where the slider is furthest from the piston when it moves to the position furthest from the first liquid storage unit 21.

[0141] In a preferred embodiment, the oral care liquid preparation device provided by the present invention further includes a housing; the housing is used to fix each unit of the oral care liquid preparation device; and the housing has an opening for disassembling the first liquid storage unit 21.

[0142] Understandably, the housing is used to securely house the various units within it, providing a mounting base and support structure for each unit and its components. This prevents displacement or damage during equipment operation due to vibration or movement, ensuring that each unit and its components remain in the correct position and maintain appropriate spacing and protection between them and the external environment. The housing is equipped with fixing points, slots, screw holes, etc., to facilitate the orderly arrangement and fixing of each unit and its components. This also facilitates the management and maintenance of internal power or communication cables and optimizes space utilization. Furthermore, the body of the second liquid storage unit 23 can be housed not only inside the housing but also outside the housing and can be detachably connected to it to facilitate cleaning of the interior of the second liquid storage unit 23. The first liquid storage unit 21 can be directly removed from the oral care liquid preparation device through the opening on the housing.

[0143] Furthermore, the shell has a detachable or closable hatch at its opening. For example, the hatch is hinged to the shell via a pivot, and a snap-fit ​​structure or magnetic latch is provided at the hatch and shell cover. The hatch protects the unit components inside the shell. If there is more than one opening, multiple openings can share one hatch or use different hatches. A third detection element is provided at the connection between the hatch and the shell to detect whether the hatch is open. The third detection element can be controlled and connected to the first drive device. When the third detection element detects that the hatch is open, the first power unit 22 can begin to move away from the first liquid storage unit 21, making the first liquid storage unit 21 easier to remove. The third detection element can be a magnetic switch (with a magnet and a magnetic switch installed on the hatch and shell respectively), a micro switch, a proximity sensor, a limit switch, etc.

[0144] In one specific embodiment, the first liquid storage unit 21 includes a first liquid storage body and a piston; one end of the first liquid storage body is open, and the other end of the first liquid storage body is provided with a third liquid outlet; the piston is slidably disposed within the first liquid storage body; the first power unit 22 includes a first driving device, a transmission mechanism, a slider, a first detection element for detecting whether the slider has moved to a position in contact with the piston, and a second detection element for detecting whether the slider has moved to the position furthest from the first liquid storage unit 21; the first driving device is drivenly connected to the transmission mechanism, and the transmission mechanism is drivenly connected to the slider; the first driving device is used to drive the transmission mechanism to make the slider move linearly; the slider is used to push the piston; a hatch is detachably or openably disposed at the opening of the housing, and a third detection element for detecting whether the hatch is open is disposed at the connection between the hatch and the housing. In this specific embodiment, when the third detection element detects that the hatch is open, the first driving device is activated to make the slider start to move away from the piston; when the second detection element detects that the slider has moved to the position furthest from the first liquid storage unit 21, the first driving device is paused; when the third detection element detects that the hatch is closed, the first driving device is activated to make the slider start to move towards the piston; when the first detection element detects that the slider has moved to the position of contact with the piston, the first driving device is paused.

[0145] The opening on the shell can be specifically located on the side or top of the shell; in a specific embodiment, the opening and hatch are located on the top of the shell, and a space for accommodating the first liquid storage unit 21 is formed inside the shell below the opening. The first liquid storage unit 21 includes a first liquid storage body and a piston. One end of the first liquid storage body is open, and the other end of the first liquid storage body is provided with a third liquid outlet. The piston is slidably disposed within the first liquid storage body. The first power unit 22 is disposed below the first liquid storage body. The first power unit 22 includes a first driving device, a transmission mechanism, and a slider. The transmission mechanism is connected to the drive mechanism, which in turn is connected to the slider. The first drive device drives the transmission mechanism to make the slider move linearly, and the slider pushes the piston. To allow the first liquid storage unit 21 to be directly pushed in from the open port for installation and to be directly connected to the mixing unit 25 during installation, the open end of the first liquid storage body must be pushed into the open port before installing the first liquid storage unit 21. A liquid outlet bend is sealed at the third liquid outlet, and the liquid outlet bends in the installation direction of pushing the first liquid storage unit 21 into the open port. The first liquid storage unit 21 and the mixing unit 25 are connected by a... The pipe connecting the first liquid storage unit 21 and the mixing unit 25 is detachably and sealed to the outlet elbow after installation. This can be achieved by installing a rubber valve or other sealing device inside the pipe connecting the outlet elbow in the pipe connecting the first liquid storage unit 21 and the mixing unit 25. To position the second liquid storage unit 23 above the first liquid storage unit 21 and the mixing unit 25, the second liquid storage unit 23 is detachably mounted on the top of the housing. Therefore, a hole is provided in the hatch for the second liquid storage unit 23. 3. The pipe connecting to the mixing unit 25 passes through; a component to assist in removing the first liquid storage unit 21 may be provided at one end of the first liquid storage body near the third liquid outlet, such as a handle 114 or a handle that is integrally formed or assembled separately; in this specific embodiment, although the second liquid storage unit 23 needs to be removed before opening the hatch to replace the first liquid storage unit 21, since the sliding direction of the slider is the same as the direction of installation and removal of the first liquid storage unit 21, the old first liquid storage unit 21 can be taken out directly by opening the hatch without waiting for the slider of the first power unit 22 to descend to the lowest position. The third liquid outlet and the liquid outlet elbow can be sealed together by an elastic gasket or other sealing material. A rotating element can be installed at the connection between the third liquid outlet and the liquid outlet elbow. This rotating element is designed with a through hole and a partition structure. The through hole or partition structure in the rotating element can rotate a certain angle along the axis of the third liquid outlet with the liquid outlet elbow. When the third liquid outlet and the liquid outlet elbow are at a certain preset rotation position, the through hole is aligned, and the third liquid outlet and the liquid outlet elbow are connected. When rotated to another preset rotation position, the partition structure will intervene, so that the third liquid outlet and the liquid outlet elbow are disconnected, so that the unused first liquid storage unit 21 can be restored to a sealed state by rotating the liquid outlet elbow after removal.

[0146] In another specific embodiment, the opening and hatch are located on the side of the shell. A space is formed inside the shell, directly opposite the opening, to accommodate the first liquid storage unit 21. The first liquid storage unit 21 includes a first liquid storage body and a piston. One end of the first liquid storage body is open, and a third liquid outlet is located on the side of the other end of the first liquid storage body. The piston is slidably disposed within the first liquid storage body. A first power unit 22 is located above the first liquid storage body. The first power unit 22 includes a first driving device, a transmission mechanism, and a slider. The first driving device is drivenly connected to the transmission mechanism, and the transmission mechanism is driven by the slider. The first driving device is used to drive the transmission mechanism to make the slider move linearly, and the slider is used to push the piston. In order to allow the first liquid storage unit 21 to be directly pushed in from the open port for installation and to be directly connected to the mixing unit 25 during installation, the orientation of the third outlet is the same as the installation direction of the first liquid storage unit 21 being pushed into the open port. The pipe connecting the first liquid storage unit 21 and the mixing unit 25, with the pipe opening connected to the third outlet facing the open port, is positioned so that the third outlet is directly opposite the pipe opening when installing the first liquid storage unit 21. The first liquid storage unit 21 and the mixing unit... The pipe connecting the first liquid storage unit 21 and the mixing unit 25 to the third liquid outlet is detachably and sealed after installation. This can be achieved by installing a rubber valve or other sealing device in the pipe connecting the first liquid storage unit 21 and the mixing unit 25 to the third liquid outlet. An auxiliary component for removing the first liquid storage unit can be provided on its side. For example, it could be a piece of paper partially pasted to the side of the first liquid storage unit. Pulling the unpainted part of the paper helps to remove the first liquid storage unit. Product information can also be printed on the paper. An auxiliary space for removal can be provided at the edge of the open opening. The groove on the edge facilitates the user to remove the first liquid storage unit. In this specific embodiment, the second liquid storage unit 23 does not need to be disassembled before opening the hatch to replace the first liquid storage unit 21. However, the first liquid storage unit 21 can only be removed after the slider of the first power unit 22 moves back to the position furthest from the first liquid storage unit 21. Since the hatch is not located on the top of the housing, the top of the housing can be open and directly connected to the bottom of the second liquid storage unit. A sealing ring or other sealing element can be provided at the connection between the top of the housing and the second liquid storage unit to prevent liquid from entering the housing from the connection.

[0147] In a preferred embodiment, tap water is typically used as the diluent to facilitate the acquisition of the diluent. However, tap water may contain minute impurities and / or microorganisms, posing certain safety risks. Therefore, the oral care solution preparation device provided by the present invention further includes a filtration unit. The bottom of the second liquid storage unit 23 is provided with a second liquid outlet for communicating with the mixing unit 25. The filtration unit is located at the second liquid outlet of the second liquid storage unit 23, or in the pipe connecting the second liquid storage unit 23 and the mixing unit 25.

[0148] It is understandable that a spring stop valve can be installed at the second liquid outlet, and a valve opening mechanism for opening the spring stop valve can be installed at the pipe opening of the pipe connecting the second liquid storage unit and the mixing unit. The diluent in the second liquid storage unit 23 must be filtered by the filtration unit before entering the mixing unit 25. The filtration unit includes filter media and a support structure for fixing the filter media.

[0149] The filtration unit can be installed within the second liquid storage unit. Specifically, the filtration unit may include a filter element and a filter element housing. The filter element is located at the second liquid outlet of the second liquid storage unit, and the filter element housing is located outside the filter element and detachably connected to the bottom of the second liquid storage unit. A handle may be installed on the top of the filter element housing or integrally formed therein, facilitating user removal of the filter element housing. More specifically, the filter element housing can be fixedly connected to the inner wall of the bottom of the second liquid storage unit via a rotating lock. A locking block is provided at the lower end of the filter element housing, and a locking groove matching the locking block is provided on the inner wall of the bottom of the second liquid storage unit. This fixed connection method facilitates disassembly and replacement of the filter element. The filter element may be a filter with anti-slip properties. Filter cartridges with antibacterial and / or antimicrobial functions, such as silver ion implanted filter cartridges and ultrafiltration membrane filter cartridges; furthermore, the filter cartridge can be annular columnar, leaving an installation position for the spring stop valve. After the filter cartridge housing is connected to the inner wall of the bottom of the second liquid storage unit, the inner top surface of the filter cartridge housing can seal the hole at the top of the filter cartridge; a filter cartridge bottom cover is installed at the bottom of the filter cartridge. The filter cartridge bottom cover is annular and fits the bottom of the filter cartridge. After long-term use, the filter cartridge may become loose or partially fall off due to the accumulation of internal impurities. The filter cartridge bottom cover can provide certain support for the filter cartridge by cooperating with the bottom structure of the filter cartridge, so that the filter cartridge can maintain a certain integrity when it is removed by the user.

[0150] The filter housing should allow liquid from the second liquid storage unit to enter it; in one specific embodiment, a drainage hole is provided on the side of the filter housing; in another specific embodiment, a gap is left at the detachable connection between the filter housing and the bottom of the second liquid storage unit, or a drainage space is provided at the lower end of the filter housing, so that liquid from the second liquid storage unit can enter the filter housing from the gap or the drainage space.

[0151] In a preferred embodiment, the bottom or side of the housing may be provided with a magnetic element that can attract a mouthwash container made of a ferromagnetic or ferrimagnetic material.

[0152] In a preferred embodiment, a wall-mounting plate is provided on the side of the housing, and the wall-mounting plate has mounting holes, through which the oral care liquid dispensing device can be fixed to the wall; further, the area of ​​the wall-mounting plate can be wider than the side of the housing to which it is fixedly connected, and magnetic elements can be provided on the wider part, so that a mouthwash container made of ferromagnetic or ferrimagnetic material can be attracted to it.

[0153] In a preferred embodiment, a vertical support is provided on the outside of the housing, which allows the oral care liquid preparation device provided by the present invention to be placed upright on a table.

[0154] In a preferred embodiment, the oral care solution preparation device provided by the present invention further includes a control unit for controlling the working state of each electrically powered component of the oral care solution preparation device.

[0155] The control unit can communicate with each energized component. The energized components of the oral care solution preparation device include, but are not limited to, the first power unit 22, the second power unit 24, the first valve, the second valve, the display unit, the detection unit, the interaction unit, the control unit, each detection element, and the power supply unit. Specifically, the control unit is used to acquire the detection data of the detection unit and each detection element, to acquire the working status of the first power unit 22 and the second power unit 24 and the real-time position of the drive component, to process the acquired data, to send the processed data to the display unit, to acquire the remaining power of the power supply unit, and to control the start and stop of each power unit and the opening and closing of each valve. Specifically, the control unit can calculate the current remaining amount of the corresponding first storage unit 21 based on the pre-set relationship between the moving distance of the slider of the first power unit 22 and the output volume of the concentrate, combined with the moving distance of the slider of the first power unit 22 when the slider moves to the position of contact with the piston detected by the first detection element, or the real-time moving distance of the slider, and send it to the display unit for display; the control unit can send a warning message to the display unit and an alarm command to the sound reminder unit when the current remaining amount of the first storage unit 21 is less than the preset amount and the water level of the second storage unit 23 is lower than the preset water level; if the first detection element still does not detect the slider contacting the foreign object when the slider moves to the maximum stroke position of the first storage unit 21, or the first detection element only detects the slider contacting the foreign object when the slider moves to the preset position (the position when the slider moves to the door or shell), then the control unit can determine that the first storage unit 21 corresponding to the first power unit 22 is not installed, and send it to the display unit for display; when the control unit receives interactive data from the interactive unit, it can... By controlling the start and stop of each power unit and the opening and closing of each valve, the device can enter different working modes, including liquid preparation mode, pipeline flushing mode, etc. When the oral care liquid preparation device provided by this invention is not in any working mode, each valve is closed and each power unit is paused. When the user selects the pipeline flushing mode through the interactive unit, the control unit controls the second valve to open and the second power unit 24 to start. The diluent in the second storage unit can flush the mixing unit 25 and the pipeline currently connected to the mixing unit 25, cleaning up any concentrate that may have remained from the previous liquid preparation. When the user selects the liquid preparation mode through the interactive unit and sets or selects the liquid preparation parameters (such as selecting a certain flavor, corresponding to the specific concentration and concentrate formula built into the control unit), the control unit can start the second power unit 24 according to the liquid preparation parameters, and then start the first power unit 22 corresponding to the required concentrate in sequence, quantitatively delivering the diluent and the required concentrate to the mixing unit 25 respectively. The starting order is not specifically limited. The control unit can control the power unit to pause after each power unit has delivered the amount corresponding to the liquid preparation parameters.

[0156] Furthermore, contact or non-contact information transmission tags containing different information can be set on the outside of the first liquid storage unit 21 with different flavors. Correspondingly, an identification device for reading the content of the information transmission tag can be set next to the first liquid storage unit 21. The identification device sends the read data to the control unit. The control unit can identify the flavor information of the first liquid storage unit 21 and send it to the display unit for display.

[0157] In a preferred embodiment, the oral care solution preparation device provided by the present invention further includes a display unit for displaying the working information of the oral care solution preparation device. The display unit can be a display screen disposed outside the housing. The display screen can communicate with each powered component to directly obtain their data, or communicate with the control unit to receive data processed by the control unit, displaying information such as the device's working mode, the remaining power of the power supply unit, the remaining capacity of each first liquid storage unit 21, and interactive content. When the display screen is a touch screen, the user can directly select the working mode and set the liquid preparation parameters on the display screen. When the opening and the door are disposed on the side of the housing, the display screen can be disposed on the housing covered by the door. In this case, the door can be made of a light-transmitting mirror. When the display screen displays information, light can penetrate the door, and the user can see the information on the display screen clearly. The door not only protects the display screen from external physical damage, but also, when the display screen is not working, the light-transmitting mirror door looks like an ordinary mirror, which can improve the overall aesthetics of the device.

[0158] In a preferred embodiment, the oral care liquid dispensing device provided by the present invention further includes a detection unit for detecting whether an object is approaching. The detection unit may specifically include an infrared distance sensor disposed on the front of the device. When the device is not in use, the display unit may remain in a screen-off state or only display a small amount of information, including the remaining battery level, in a screen saver state. When an object is detected by the infrared distance sensor within a preset range, the infrared distance sensor sends a wake-up command to the display unit, or sends it to the control unit and then to the display unit, so that the display unit enters a normal display state. When no object is detected by the infrared distance sensor within a preset range within a preset time, it can be confirmed that the device is not in use. The infrared distance sensor may send a sleep command to the display unit, or send it to the control unit and then to the display unit, so that the display unit enters a screen-off state or a screen saver state.

[0159] In a preferred embodiment, the oral care solution preparation device provided by the present invention further includes an interaction unit for enabling interaction between the user and the oral care solution preparation device. The interaction unit can be multiple buttons located on the front of the device; in a specific embodiment, the interaction unit includes three buttons located on the front of the device housing, each button having a backlight, and the button functions can be: dispensing, mode selection, and flavor selection, respectively.

[0161] In a preferred embodiment, the oral care solution preparation device provided by the present invention further includes a sound reminder unit for providing audio reminders of interactive information or the operation information of the oral care solution preparation device. Specifically, the sound reminder unit can communicate with each powered component to directly obtain their data, or communicate with the control unit to receive data processed by the control unit. The sound reminder unit can be a buzzer or a voice module, and can play the key tones of the interactive unit and reminders such as insufficient battery power, insufficient concentrate, and insufficient diluent.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
