DETAILED DESCRIPTION OF THE INVENTION

[0021] The following clearly and completely describes the technical solutions of the embodiments of the present application, combined with the drawings of the embodiments of the present application, and the described embodiments are not all embodiments but only a part of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without any inventive effort fall within the scope of protection of the present application.

[0022] As shown in Figures 1 to 4, an embodiment of one aspect of the present application discloses an oral care liquid placement device, which includes a first liquid storage unit 100, a first power unit 200, a second liquid storage unit 300, a second power unit 400, a liquid mixing unit 500, and a control device.

[0023] Specifically, the first liquid storage unit 100 stores the concentrated liquid, the first power unit 200 provides power to output the concentrated liquid from the first liquid storage unit 100, the second liquid storage unit 300 stores the diluted liquid, the second power unit 400 provides power to output the diluted liquid from the second liquid storage unit 300, the liquid mixing unit 500 is connected to the first liquid storage unit 100 and the second liquid storage unit 300 respectively and contains the liquid output from the first liquid storage unit 100 and the second liquid storage unit 300, and the control device controls the operation of the first power unit 200 and the second power unit 400 respectively, thereby allowing the concentrated liquid and the diluted liquid to be mixed in the liquid mixing unit 500 according to a predetermined ratio.

[0024] In the embodiment of the present application, different parameters are set, and the output amount of the concentrated liquid and the diluted liquid is controlled by the control device, and mixed according to the ratio in the liquid mixing unit 500, thereby producing oral care liquids with different concentration ratios, which can meet the needs of users in different situations and functions and improve the usage experience.

[0025] Here, in some embodiments, the first liquid storage unit 100, the second liquid storage unit 300, the second power unit 400, and the liquid mixing unit 500 are connected by pipelines, the concentrate is an undiluted liquid ingredient for disposing of the oral care liquid, which contains a high concentration of the active ingredient of the oral care liquid, and the diluent is a liquid ingredient that is mixed with the concentrate to reach the usage concentration. Generally, the diluent is water, but depending on the formulation of different oral care liquids, it may also be an easily available solvent such as saline, alcohol, etc.

[0026] In some embodiments, the first power unit 200 specifically provides power for outputting the concentrated liquid from the first liquid storage unit 100. After the first power unit 200 is started, the concentrated liquid is extruded, pressed, or pushed from the first liquid storage unit 100. A first valve is provided in the pipeline connected between the first liquid storage unit 100 and the liquid mixing unit 500. When the first power unit 200 is operating, the first valve is opened, and after the first power unit 200 stops operating, the first valve is closed, so that when the second power unit 400 is operating, the concentrated liquid is extruded, pressed, or pushed from the first liquid storage unit 100. In order to avoid extracting concentrated liquid from the liquid storage unit 500, when the number of first liquid storage units 100 and first power units 200 is N, a first valve is provided in each of the pipelines connected between each first liquid storage unit 100 and the liquid mixing unit 500, and the number of first valves is also N, and the first valves may be solenoid valves, one-way valves, duckbill valves, etc. When the number of first liquid storage units 100 and first power units 200 is two, the two sets of first liquid storage units 100 and first power units 200 are arranged symmetrically to make the internal layout of the equipment more compact.

[0027] In some embodiments, the first liquid storage unit 100 is a flexible or rigid container with a uniform shape, where the container wall thickness is maintained uniformly throughout or varies according to a predetermined rule, and the cross section is maintained uniformly along the height direction or varies gradually according to design needs, thereby maintaining the consistency of fluid pressure, avoiding local overpressure or uneven flow rate, and ensuring efficient and stable liquid transmission. A different first power unit 200 can be selected to suit first liquid storage units 100 of different shapes, structures, and materials. For example, when a soft first liquid storage unit 100 is used, an extrusion mechanism having an extrusion structure such as a pressure plate or drum can be used for the first power unit 200 to apply a constant pressure to the container wall of the first liquid storage unit 100 to deform it, and then extrude the concentrated liquid in the first liquid storage unit 100 at a constant speed. When a first liquid storage unit 100 having a piston structure and a uniform shape is used, a stepping motor, compression spring, or other driving device and corresponding transmission mechanism can be used for the first power unit 200 to push the piston of the first liquid storage unit 100 to change the volume of the first liquid storage unit 100, and discharge the concentrated liquid from the first liquid storage unit 100. By controlling the movement distance of the piston structure, a quantitative output of the concentrated liquid can be achieved.

[0028] In some embodiments, the first liquid storage unit 100 is provided with an output port communicating with the liquid mixing unit 500, and the pipe connected between the first liquid storage unit 100 and the liquid mixing unit 500 is removably sealed and connected to the output port, thereby allowing the user to replace a new first liquid storage unit 100 by themselves.

[0029] In some embodiments, the second power unit 400 specifically provides power to output the diluent from the second liquid storage unit 300 at a constant speed, and after the second power unit 400 is started, the amount of diluent output per unit time is constant. The second power unit 400 may be a water pump that can provide a constant flow rate, such as a centrifugal pump or a plunger pump. A second valve is provided in the pipeline connected between the second liquid storage unit 300 and the liquid mixing unit 500. When the second power unit 400 is operating, the second valve is opened, and after the operation of the second power unit 400 is stopped, the second valve is closed.

[0030] Furthermore, the second power unit 400 may be a water pump with a self-locking function, thereby eliminating the need for a second valve. A self-locking water pump is a water pump equipped with a mechanical self-locking valve inside, which automatically cuts off the passage between the water inlet and outlet of the water pump when the water supply pressure is lower than the self-locking force of the valve when the water pump is not operating. Specifically, the water pump may have a two-way sealing structure, and when the water pump is not operating and hydraulic pressure reverses or enters the water pump, the self-locking door panel of the valve automatically closes and seals according to the direction of the liquid flow. A self-locking water pump may also have a pressure sensing element to achieve the self-locking function of the water pump, which detects changes in the liquid pressure on both the inlet and outlet sides of the water pump and controls the opening and closing of the internal valve of the water pump.

[0031] In some embodiments, the second liquid storage unit 300 may be a water tank, and may include a second liquid storage body with a partially or fully open top, and a top lid that covers the open portion of the top of the second liquid storage body, allowing the diluent to be easily refilled or replaced. In order to prevent the liquid in the liquid mixing unit 500 from flowing back into the second liquid storage unit 300, the second liquid storage unit 300 is installed above the first liquid storage unit 100 and the liquid mixing unit 500. When the diluent in the second liquid storage unit 300 becomes insufficient, air will enter the pipeline through the liquid outlet of the second liquid storage unit 300, causing the second power unit 400 to idle. Therefore, a liquid level detection element, such as a water level gauge or liquid level sensor, is installed in the second liquid storage unit 300 to detect the liquid level in the second liquid storage unit 300.

[0032] In some embodiments, the liquid mixing unit 500 may be a hollow cavity or just some piping connected to each liquid storage unit.

[0033] Hereinafter, the oral care liquid placement device disclosed in the embodiment of the present application will be specifically explained in conjunction with FIGS. 1 to 4. FIG.

[0034] In the related art, there is another problem that stored mouthwash is a product that is pre-purchased by the consumer, and each time it is filled, the flavor is uniform, and the user's experience is also uniform.

[0035] In order to solve the technical problem of a single taste, in some embodiments of the present application, as shown in Figures 2 to 3, the number of first liquid storage units 100 is at least one, the number of first power units 200, the number of liquid mixing units 500 and the number of first liquid storage units 100 are the same, the first power units 200, the first liquid storage units 100 and the liquid mixing units 500 are arranged correspondingly, and the control device controls to operate at least one first power unit 200 and one second power unit 400, respectively.

[0036] According to taste needs, a machine with a corresponding number of first liquid storage units 100 can be selected, or a corresponding number of first liquid storage units 100 can be arranged in the machine, with each first liquid storage unit 100 containing a different concentrate, and the concentrate can be output through one built-in first liquid storage unit 100 and mixed with water according to a ratio to discharge the liquid, or multiple first liquid storage units 100 can simultaneously mix with water according to a ratio to discharge the liquid, thereby realizing the function of discharging liquid with a single taste, different tastes, or a mixture of multiple tastes.

[0037] Here, the second liquid storage unit 300 is connected to each mixing unit by a pipeline, and each first liquid storage unit 100 is connected to a corresponding mixing unit, and the control device mixes concentrated oral care liquid and water according to different mixing ratios to prepare oral care liquids of specific flavors and different concentrations, and in combination with specific portable containers, users can meet their needs for oral cleansing and breath freshening in multiple situations. The oral care liquid dispensing device can simultaneously accommodate one or more first liquid storage units 100 containing concentrates, and by adding concentrated oral care liquid bullets of different flavors, the machine can achieve a multi-flavor mixture, enriching the user's experience.

[0038] Here, in order to automatically mix water and concentrate according to different ratios and discharge the liquid with higher accuracy, the design of the waterway structure through which the concentrate flows from the liquid outlet of the first liquid storage unit 100 into the liquid mixing unit 500 is also a key point in realizing the above functions.

[0039] In contrast, in some embodiments of the present application, the liquid mixing unit 500 includes a check valve 510 and a liquid mixing chamber 520, and the liquid mixing chamber 520 mixes the concentrated liquid and the diluted liquid before discharging them, and the check valve 510 is arranged to conduct the concentrated liquid in one direction along the flow direction from the first liquid storage unit 100 to the liquid mixing chamber 520.

[0040] Due to the design of the check valve 510 and the liquid mixing chamber 520, the concentrate flowing out from the liquid outlet of the first liquid storage unit 100 flows through the one-way check valve 510 into the liquid mixing chamber 520, where it is mixed with water and discharged, thereby ensuring that the machine adheres to the mixing ratio every time. The check valve 510 only allows the concentrate in the flavor bottle to flow in one direction into the liquid mixing chamber 520, pushing a predetermined amount of concentrate into the liquid mixing chamber 520. The pump extracts a predetermined amount of water from the second liquid storage unit 300 and mixes it with the concentrate. During the water extraction process, the remaining concentrate in the first liquid storage unit 100 is not extracted, and the liquid mixing chamber 520 mixes the concentrate and water and discharges it, ensuring the accuracy of the mixing ratio.

[0041] The oral care liquid dispensing device disclosed in the embodiments of the present application can ensure the accuracy of the mixing ratio of water and concentrate and provide good antibacterial and cleansing effects for oral care liquids of various concentrations. To achieve this function, it uses a one-way check valve 510 and a liquid mixing chamber 520. The concentrate flows from the liquid outlet to the one-way check valve 510 and then from the one-way check valve 510 to the liquid mixing chamber 520. The two concentrates of different flavors are mixed in the liquid mixing chamber 520, and the water pump extracts water from the second liquid storage unit 300 and mixes it with the concentrate in the liquid mixing chamber 520, thus producing oral care liquids of different flavors and concentrations. During the mixing process, the check valve 510 ensures that the predetermined amount of concentrate flows smoothly into the liquid mixing chamber 520 and prevents the pump from extracting excess concentrate from the first liquid storage unit 100.

[0042] Here, in order to automatically mix water and raw liquid according to different ratios and to achieve higher accuracy in discharging the liquid, the control method and structural design of the first power unit 200 are of key importance.

[0043] In contrast, in some embodiments of the present application, the first power unit 200 includes a drive member 220 that provides power for outputting the concentrate from within the first liquid storage unit 100 .

[0044] Furthermore, the first power unit 200 includes a detection member 210 for detecting operating parameter information of the driving member 220, and the control device is configured to combine a predetermined ratio and control the driving member 220 based on the detection information of the detection member 210.

[0045] The detection member 210 accurately controls the operating parameter information of the driving member 220, and by setting different parameters, it controls the flow of a predetermined amount of concentrate, and further cooperates with the water pump to extract a predetermined amount of water, thereby producing oral care liquids with different concentration ratios.

[0046] In some embodiments, when using a first liquid storage unit 100 having a piston structure and a uniform shape, a stepping motor, a compression spring or other driving device and a corresponding transmission mechanism may be used for the first power unit 200, which pushes the piston of the first liquid storage unit 100 to change the volume of the first liquid storage unit 100, thereby discharging the concentrated liquid from the first liquid storage unit 100, and achieving a quantitative output of the concentrated liquid by controlling the movement distance of the piston structure.

[0047] Here, the driving member 220 may include a stepping motor, a compression spring or other driving device and a corresponding transmission mechanism, and correspondingly, regardless of the motion mode (rotational motion, linear motion, swinging motion, etc.) output by the driving device, the transmission mechanism has the ability to convert it into linear motion of the slider, and further move the piston.

[0048] In some embodiments of the present application, the drive member 220 includes a motor module 221, a screw rod module 222, and a push rod module 223, the push rod module 223 is mounted on the screw rod module 222, and the motor module 221 drives the screw rod module 222 to move the push rod module 223.

[0049] The first liquid storage unit 100 is a container having a piston structure, and when the push rod module 223 moves, the piston structure can be driven to discharge the concentrated liquid from within the first liquid storage unit 100.

[0050] In some embodiments of the present application, the detection member 210 includes a Hall sensor that detects the rotation speed information of the motor module 221, and the control device receives a signal from the Hall sensor.

[0051] Here, after the piston structure moves under the action of the first power unit 200, it changes the volume of the cavity of the first liquid storage body, and the first power unit 200 includes a deceleration motor, a stepping motor, a compression spring or other driving device for pushing the piston to perform linear motion, and a corresponding transmission mechanism, and the first liquid storage unit 100 can be a rigid and uniform container, for example a cylindrical container, and the concentrated liquid is filled into the first liquid storage body, and when the first liquid storage body is full of concentrated liquid, the piston is in a position close to the open end of the first liquid storage body, and when the concentrated liquid in the first liquid storage body is gone, the piston moves to a position contacting the inner wall of the other end of the first liquid storage body.

[0052] The piston includes a hard piston portion, and a sliding sealed connection is formed between the hard piston portion and the first liquid storage body, and the sliding sealed connection is achieved by tight engagement between the hard piston portion and the inside of the first liquid storage body or by the arrangement of a sealing structure such as a filler seal, a mechanical seal, or a labyrinth seal.

[0053] In some embodiments, the piston includes a soft piston portion and a hard piston portion, the soft piston portion partially or completely enveloping the exterior of the hard piston portion, and the soft piston portion enveloping at least the contact position between the piston and the inside of the first liquid storage body, so that the sliding contact surface between the soft piston portion and the inside of the first liquid storage body can form an effective sealing interface, the hard piston portion is made of a material with a certain hardness, such as hard plastic, hard alloy, ceramics, etc., here, not specifically limited, the soft piston portion is preferably made of an elastic material, and further, a multi-layer annular trench is provided at the contact position between the soft piston portion and the inside of the first liquid storage body along the sliding direction of the piston, which does not affect the sealing effect and makes the piston slide more smoothly.

[0054] In a specific embodiment, the driving member 220 includes a driving device (e.g., a motor) that outputs rotational motion and a transmission mechanism, the transmission mechanism including a screw and a guide rod, a slider that is meshed with and connected to the screw and slidably connected to the guide rod, the screw and the guide rod are longitudinally aligned, the driving device drives the screw to rotate, and the slider moves along the longitudinal direction of the guide rod when driven by the screw. The rotation of the screw rod drives the slider to slide, which further drives the push rod module 223 to push the piston structure and discharge the liquid, and a Hall sensor is provided on the reduction motor, which ensures control accuracy based on the Hall sensor to discharge different amounts of concentrate to mix with water, and further discharge mouthwash of different concentrations and / or different flavors.

[0055] In some embodiments, the motor module 221 includes a deceleration motor for driving the push rod module 223 via a transmission mechanism to move up and down to push out the concentrate. The push rod module 223 is also provided with a device switch for transmitting a signal to ensure the accuracy of the liquid discharge. The Hall sensor includes a Hall switch for generating a signal for the rotation speed of the deceleration motor.

[0056] In some embodiments, the push rod module 223 includes a push rod, a push rod base, a holder, a bearing, and a push rod shaft, etc. The holder acts to fix the reduction motor, the push rod base, the bearing, and the push rod, the push rod base cooperates with the push rod shaft to limit the position of the push rod and to provide an up and down sliding and guiding function for the push rod, and the bearing positions the tail end of the screw rod of the reduction motor.

[0057] In some embodiments of the present application, the second power unit 400 includes a water pump that extracts a predetermined amount of diluted liquid from the second liquid storage unit 300 to the liquid mixing unit 500, and by setting different parameters, it controls to discharge a predetermined amount of original liquid, and further cooperates with the water pump to extract a predetermined amount of water to produce oral care liquids with different concentration ratios.

[0058] In some embodiments of the present application, the oral-care liquid dispensing device further includes a housing unit 600, and in some embodiments, the first liquid storage unit 100, the first power unit 200, the second liquid storage unit 300, the second power unit 400, the liquid mixing unit 500, and the control device are all provided in the housing unit 600. To further improve the user experience, common structures such as a mirror, a mounting holder, and an interactive screen may be arranged on the surface of the housing unit 600 to meet the needs of specific situations.

[0059] In some embodiments, the first liquid storage unit 100 and the housing unit 600 are removably connected to allow a user to more easily install or remove it from the machine.

[0060] In some embodiments of the present application, the housing unit 600 is provided with an opening for removing the first liquid storage unit 100, and the opening of the housing unit 600 is provided with an openable and closable door 610.

[0061] Here, the design of the door 610 hides the concentrate chamber of the housing unit 600, that is, maintains the beauty of the product's external appearance. In some embodiments, the opening and door 610 are provided in the housing, and a space capable of accommodating the first liquid storage unit 100 is formed in the housing at a position opposite the opening. In this specific embodiment, before opening the door 610 to replace the first liquid storage unit 100, it is not necessary to remove the second liquid storage unit 300, but the first liquid storage unit 100 can only be removed when the slider of the first power unit 200 has moved back to the position farthest from the first liquid storage unit 100.

[0062] In some embodiments, upon opening the door, the motor module 221 can be activated to lift the push rod module 223, allowing the user to easily install or remove the first liquid storage unit 100.

[0063] In some embodiments of the present application, the second liquid storage unit 300 and the housing unit 600 are detachably connected. Here, after using the oral-care liquid dispensing device for a while, the user may need to replace or clean the diluent in the second liquid storage unit 300. In this case, the user can remove the second liquid storage unit 300 separately to replace the diluent.

[0064] In some embodiments, a filter member 320 is provided in the second liquid storage unit 300, so that consumers can easily add tap water. When the water in the second liquid storage unit 300 runs out, they can directly fill the second liquid storage unit 300 with diluted liquid, which will be filtered by the filter member 320, making it more convenient and easy to use.

[0065] In some embodiments, a carbon fiber element is used inside the filter member 320 to filter out harmful substances in tap water, making it safer and more reliable to use and reducing water bills for consumers (no need to purchase purified water or tap water; simply add tap water to the second liquid storage unit 300 and it can be used).

[0066] In some embodiments of the present application, the second liquid storage unit 300 has a liquid outlet, and the liquid outlet is provided with a valve member 310; The valve member 310 is positioned to connect the liquid outlet to the second power unit 400 when the second liquid storage unit 300 is connected to the housing unit 600, and to block the liquid outlet from the second power unit 400 when the second liquid storage unit 300 is removed from the housing unit 600.

[0067] Here, the liquid outlet of the second liquid storage unit 300 is arranged to be openable and closable and to have a leak-proof structure, and when the consumer removes the second liquid storage unit 300 to replace the water, the liquid outlet is closed, and when the second liquid storage unit 300 is attached to the housing unit 600, the liquid outlet is opened, and thus water enters the pipeline inside the housing unit 600.

[0068] In some embodiments, the valve member 310 includes a valve seat, a valve sleeve, a spring, and a sealing ring, etc., where the valve seat fixes the spring and sealing ring to perform a fixing and sealing function, the valve sleeve is assembled to the second liquid storage unit 300 to perform a sealing and water-permeable function, the sealing ring seals to prevent water leakage when changing water in the second liquid storage unit 300, and the spring resets the valve seat to open or close the valve at the appropriate time.

[0069] The oral care liquid placement device of the present application will be described in detail below using specific examples, where the following examples do not limit the present application but are merely illustrative.

[0070] 1 to 4, the oral care liquid dispensing device of this embodiment can accurately mix concentrate and water according to different ratios to produce oral care liquids of different concentrations. It can also accommodate more than one concentrate pellet, so when different flavor concentrate pellets are inserted, it can achieve the functions of dispensing a single flavor liquid or a mixed flavor liquid. To achieve this function, the internal push rod module 223 structure is used, and the slider is moved by the rotation of the screw rod, and the mixing ratio of different flavors and concentrations is controlled by the precise measurement of the Hall switch.

[0071] Furthermore, the oral care liquid dispensing device of the present application can ensure the accuracy of the mixing ratio between water and concentrate, and provide oral care liquids of various concentrations with good antibacterial and sanitizing effects. To achieve this function, it uses a one-way check valve 510 and a liquid mixing chamber 520 structure, where the concentrate flows from the liquid outlet to the one-way check valve 510 and then from the one-way check valve 510 to the liquid mixing chamber 520. The two concentrates of different flavors are mixed in the liquid mixing chamber 520, and the water pump extracts water from the water tank and mixes it with the concentrate in the liquid mixing chamber 520, thus producing oral care liquids of different flavors and concentrations. During this mixing process, the presence of the check valve 510 ensures that the desired amount of concentrate flows smoothly into the liquid mixing chamber 520 and prevents the pump from extracting excess concentrate from the concentrate bullet.

[0072] Finally, the first liquid storage unit 100 is easy to install and replace. By opening the door 610, the first liquid storage unit 100 can be easily installed and removed, and the water in the water tank can also be easily replaced.
