[0105] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0106] The terms "first", "second", etc. in the specification and claims of the present disclosure are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present disclosure can be implemented in an order other than those illustrated or described herein. In addition, the term "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0107] The following is combined with Figures 1 to 8 As shown, the consumable extrusion control system provided by the embodiment of the present disclosure is described in detail through specific embodiments and their application scenarios.

[0108] Example 1

[0109] Reference Figure 1 As shown, the consumable extrusion control system of the embodiment of the present disclosure includes:

[0110] The body end 1 may be an electric toothbrush body or a beauty instrument body;

[0111] A plurality of consumables bins 2 are connected to the fuselage end 1 through corresponding pipelines 4, respectively, for providing consumables to the fuselage end 1;

[0112] A plurality of first drive components 3 are respectively arranged on the pipelines 4 of the corresponding consumable bins 2, and are used to provide conveying power for the consumables in the consumable bins 2;

[0113] The control unit is arranged at the body end 1 and is used for controlling the switching of the corresponding first driving assembly 3 to operate, thereby switching the consumables in different consumable bins to be transported to the body end 1 .

[0114] In this specific embodiment of the present disclosure, the pipeline 4 includes a main pipeline 41 and at least one branch pipeline 42; the outlet of the main pipeline 41 is connected to the fuselage end 1, the inlet of the main pipeline 41 is connected to the outlet of each branch pipeline 42, and the inlet of each branch pipeline 42 is connected to the corresponding consumable bin 2; and a first drive component 3 is correspondingly arranged on each branch pipeline 42.

[0115] In particular, the first driving component 3 includes a first driving state and a second driving state. In the first driving state, the first driving component 3 transmits the consumables in the target consumable bin to the body end 1 through the corresponding pipeline; in the second driving state, the first driving component 3 moves the consumables remaining in the pipeline back to the corresponding consumable bin.

[0116] It should be noted that the first driving state is a state in which consumables are discharged from the consumable bin. Since the present invention has multiple consumable bins 2, when the consumables are switched, consumables remaining in the main path 41 from the previous consumable extrusion may cause the main path 41 to be blocked, and / or two or more consumables may be mixed during the next consumable extrusion. In order to avoid the aforementioned problems, the first driving component 3 of the present invention also includes a second driving state, which can move the residual consumables remaining in the main path back to the consumable bin 2 corresponding to the residual consumables.

[0117] In the disclosed embodiment, one branch pipeline 42 is connected to one consumable bin 2, and different branch pipelines 42 are connected to different consumable bins 2. The main pipeline 41 is connected to a plurality of branch pipelines 42 respectively, and the main pipeline 41 is arranged at one end close to the body end 1, and the outlet of each branch pipeline 42 is connected to the inlet of the main pipeline 41. By switching the first driving component 3 between the first driving state and the second driving state, it can be realized that two or more consumables can be automatically switched to be extruded in one product, so as to realize the multi-faceted cleaning of different consumables and meet more user needs.

[0118] The consumables bin 2 in the embodiment of the present disclosure is used to accommodate consumables of different types or different concentrations, and the consumables include but are not limited to toothpaste, mouthwash, facial cleanser, skin care products, etc.

[0119] The first drive assembly 3 in the embodiment of the present disclosure has the function of switching between the first drive state and the second drive state, including but not limited to a rotary pump, an air pump, etc. For example, the rotary pump includes a peristaltic pump, a gear pump, a screw pump, a rotor pump, etc., and the switching between the first drive state and the second drive state can be achieved by using the forward and reverse pumping of the rotary pump.

[0120] When the first drive component 3 of the present invention is a rotary pump, the working method of switching between the first drive state and the second drive state can be: first work forward for a first preset time, then work reversely for a second preset time, and then when the next consumable is extruded, first work forward for a first preset time, then work reversely for a second preset time. In this way, it can be avoided that the previous consumable remains in the pipeline and blocks the pipeline and contaminates the next consumable.

[0121] Optionally, if the consumable is toothpaste, the first preset time is 3 to 5 seconds to ensure that 0.4 to 1.2 g of toothpaste is pushed out, and the second preset time is 1 to 3 seconds to ensure that the toothpaste remaining in the pipeline can be drawn back into the corresponding consumable bin. It should be understood that the first preset time and the second preset time can be set according to the amount of consumables discharged from the consumable bin, the diameter and length of the main pipeline and the branch pipeline, and the speed of the rotary pump, that is, in other embodiments, the first preset time and the second preset time can also be other values, and the present disclosure does not limit this.

[0122] In another optional embodiment, the consumable extrusion control system of the present disclosure further includes:

[0123] A flow sensor is arranged on the pipeline, and the control unit controls switching between a first driving state and a second driving state of the first driving component based on a detection result of the flow sensor.

[0124] In the disclosed embodiment, the amount of consumables delivered by the rotary pump is detected by a flow sensor. After the rotary pump rotates forward until the amount of consumables detected by the flow sensor reaches a target value, the rotary pump rotates reversely until the flow rate of the consumables detected by the flow sensor is zero, and then stops reversing, thereby avoiding consumables from remaining in the pipeline. Preferably, the flow sensor is arranged on a common pipeline for multiple consumables. Optionally, the target value can be 0.4g to 1.2g.

[0125] Example 2

[0126] Reference FIG. 2A to FIG. 2C As shown, in Example 2, the consumable extrusion control system of the present disclosure further includes:

[0127] The consumable switching component 5 is used to switch the on / off state of the corresponding pipeline 4.

[0128] The control unit is used to control the operation of the consumable switching assembly 5 and the first driving assembly 3 , so as to switch the consumables in different consumable bins 2 and transport them to the body end 1 .

[0129] Specifically, the consumable switching assembly 5 includes a second driving assembly 51 and a diversion rotating disk 52 connected to the second driving assembly 51 and adapted to the plurality of consumable bins 2;

[0130] The diverter rotating disk 52 is arranged on the main line 41, and the diverter rotating disk 52 is provided with an opening 521 for connecting the main line 41 with the corresponding consumable bin 2; wherein, the diverter rotating disk 52 includes a first rotation position and a second rotation position; wherein, in the first rotation position, one of the multiple consumable bins 2 is connected to the main line 41 through the opening 521; and in the second rotation position, another one of the multiple consumable bins 2 is connected to the main line 41 through the opening 521.

[0131] The second driving component 51 is connected to the diverter rotating disk 52, and the second driving component 51 is used to drive the diverter rotating disk 52 to rotate in a linked manner, so as to connect different consumable bins 2 with the pipeline through the opening 521 of the diverter rotating disk 52, that is, the second driving component 51 drives the diverter rotating disk 52 to rotate in a linked manner, and switches between the first rotation position and the second rotation position.

[0132] Here, the first rotation position and the second rotation position are corresponding communication positions after switching different consumable bins 2 .

[0133] In the embodiment of the present disclosure, the second drive component 51 in the consumable switching component 5 is preferably a drive motor. The second drive component 51 first drives the diversion rotary disk 52 to rotate, and aligns the opening 521 of the diversion rotary disk 52 with one of the multiple consumable bins 2, such as consumable bin A, so that the consumable bin A forms a passage with the main line 41, so that the first drive component 3 can extract the corresponding consumables in the consumable bin A when it is working. The second drive component 51 drives the diversion rotary disk 52 to rotate to another consumable bin among the multiple consumable bins 2, such as consumable bin B, so that the consumable bin B forms a passage with the main line 41, so that the first drive component 3 can extract the corresponding consumables in the consumable bin B when it is working. The present disclosure can achieve the purpose of automatically switching different consumable bins through the consumable switching component 5 and the second drive component 51.

[0134] Of course, before switching from consumable bin A to consumable bin B, it is necessary to first move the consumables remaining in the main line 41 back to the consumable bin A, and then switch to the consumable bin B. For example, the first driving component 3 is a peristaltic pump, which, when rotating forward, will suck the consumables in the corresponding consumable bin and squeeze them out to the liquid outlet of the body end 1 (if the body end 1 is an electric toothbrush, the liquid outlet is the liquid outlet on the brush head), and when the peristaltic pump is reversed, the consumables remaining in the pipeline can be sucked back into the corresponding consumable bin.

[0135] Optionally, the consumable switching component 5 further includes:

[0136] A locking component (not shown) is connected to the diverter rotating disk 52; the locking component is used to control the diverter rotating disk 52 to switch between a locked state and an unlocked state; wherein, when the diverter rotating disk 52 is in the locked state, the diverter rotating disk 52 remains relatively fixed relative to the consumable bin 2; and in the unlocked state, the diverter rotating disk 52 can be driven to rotate by the second drive assembly 51.

[0137] In the disclosed embodiment, the locking component can be used to control the diverter rotating disk 52 to be in a locked state when the diverter rotating disk 52 rotates to the consumable bin 2 required by the user, so that the diverter rotating disk 52 remains relatively fixed relative to the consumable bin 2, thereby improving the stability of the consumable bin output / input consumables performance.

[0138] Optionally, the second driving component 51 can drive the diversion rotating disk 52 to rotate electrically or manually, so as to switch different consumable bins. For example, the second driving component 51 can be a toggle hand wheel or a driving motor.

[0139] It should be understood that in the present disclosure, a consumable bin 2 can be a separate consumable bottle, or multiple consumable bins 2 can be arranged in a consumable bottle. The cross-sectional shape of the consumable bottle can be circular, triangular, quadrilateral or other polygonal, and the cross-sectional shape of the consumable bin can also be one of circular, rectangular, custom patterns, etc., and the present disclosure does not limit this.

[0140] For example, when the cross section of the consumable bottle is circular, the cross sections of the multiple consumable bins 2 may be formed in the shape of multiple concentric circles or multiple fan-shaped shapes. Figure 2B and Figure 2C As shown, in a specific embodiment of the present disclosure, six consumable bins 2 are arranged in one consumable bottle, and the cross-sectional shape of the six consumable bins 2 is fan-shaped.

[0141] It should be noted that, since the internal pipeline of the consumables bin 2 is a straight pipeline, different cross-sectional shapes of the consumables bin 2 will result in different corresponding storage spaces for storing consumables.

[0142] Here, the cross-sectional shape of the consumable bin 2 is set to different shapes or patterns to meet the storage needs of consumables with different needs. For example, according to the needs of using consumables, consumables are divided into different usage levels, such as consumables of the first usage level to consumables of the third usage level. The priority of usage needs decreases successively. Different cross-sectional shapes of the consumable bin 2 can be set according to different usage levels, so as to realize the storage of consumables of different capacities and types.

[0143] It is worth mentioning that the multiple consumable bins 2 of the present disclosure can be set to be marked with different marks, which can be colors, texts, graphics, etc., so that the user knows which consumable bin to switch to.

[0144] It should be noted that the consumable switching component 5 is actually used to control the on / off status of multiple branch pipelines 42, and realizes the extrusion of the target consumable by controlling the pipeline of the target consumable and disconnecting (or closing) the pipeline of the non-target consumable.

[0145] Example 3

[0146] See also FIG. 3A to FIG. 3CAs shown, the consumable switching assembly is a new type of dual-pump head peristaltic pump structure, specifically, the first driving assembly 3 includes two pump heads respectively arranged on the corresponding branch pipelines 42, a rotating shaft 611 for connecting and driving the two pump heads, and a first rotating motor 61 connected to the rotating shaft 611, and the consumable switching assembly includes a second rotating motor 62 connected to the rotating shaft 611; the second rotating motor 62 is used to control the switching of the connection and separation states between the rotating shaft 611 and the two pump heads; the first rotating motor 61 is used to drive the corresponding pump head to work through the linkage of the rotating shaft 611, so as to transport the consumables in the corresponding branch pipeline.

[0147] In Example 3, the two pump heads are respectively the first pump head 31 and the second pump head 32. The first pump head 31 and the second pump head 32 are respectively provided on the two branch pipes 42. For example, Figure 3A When the second rotary motor 62 rotates to drive the rotary shaft 611 to connect with the first pump head 31, the consumables in the consumable bin A can be transported to the body end 1 by controlling the first rotary motor 61 to work; Figure 3B When the second rotary motor 62 rotates to drive the rotary shaft 611 to connect with the second pump head 32 , the consumables in the consumable bin B can be transported to the body end 1 by controlling the first rotary motor 61 to work.

[0148] Furthermore, in terms of the residual solution: when the first rotary motor 61 rotates forward, the first pump head 31 will work to absorb the consumables in the consumable bin A, and when the first rotary motor 61 rotates reversely, the first pump head 31 will draw the consumables remaining in the branch line 42 back into the consumable bin A. Similarly, when the rotating shaft 611 of the first rotary motor 61 is connected to the second pump head 32, the residual problem is solved in the same way as above.

[0149] It is also worth mentioning that a one-way valve can be further provided at the liquid outlet position of the body end 1, so that when the first rotating motor 61 reverses to extract the remaining consumables in the corresponding pipeline, the end of the pipeline will preferentially absorb air, so that when the first rotating motor 61 reverses, the excess consumables in the pipeline will be sucked back into the consumable bin A, thereby minimizing the suction of the squeezed consumables into the consumable bin.

[0150] It is worth mentioning that the branch pipeline connected to the consumable bin A is the first branch pipeline 421, and the branch pipeline connected to the consumable bin B is the second branch pipeline 422. The consumables in the consumable bin A are the first consumables, and the consumables in the consumable bin B are the second consumables. The remaining solutions also include: when multiple consumables are switched, due to the operation of the first pump head 31 and the consumables in the consumable bin A are squeezed out, a small part of the consumables in the first branch pipeline 421 will inevitably enter the second branch pipeline 422. Therefore, by setting the second branch pipeline 422, the consumables in the consumable bin A are squeezed out. After a pump head 31 extrude the first consumable, it first controls the second rotary motor 62 to switch to the second pump head 32, and the second rotary motor 62 rotates forward (for example, the forward rotation time of the second rotary motor 62 can be 0.5s) so that the second pump head 32 pushes out the first consumable remaining in the second branch pipeline 422, and then controls the second rotary motor 62 to switch to the first pump head 31, and the first rotary motor 61 reverses (1 to 3s) so that the first pump head 31 draws the first consumable remaining in the first branch pipeline 421 back into the consumable bin A.

[0151] It is also worth mentioning that in order to avoid the second consumable remaining in the first branch pipeline 421, or to avoid the first consumable remaining in the second branch pipeline 422, the first branch pipeline 421 and the second branch pipeline 422 should be designed to be as short as possible, so as to ensure that when the first pump head 31 is working, the consumable can enter the main pipeline from the first branch pipeline 421, and only a small amount will enter the second branch pipeline 422. When the first pump head 31 is back-pumped, it can also be ensured that the small amount of first consumable entering the second branch pipeline 422 will be back-pumped into the consumable bin A.

[0152] Reference Figure 3C As shown, it can be concluded that the function of the second rotary motor 62 is to change the position of the rotary shaft 611. In another implementation, the present disclosure can also remove the second rotary motor 62 and replace it with a manual switching method: the user can manually turn the rotary shaft of the first rotary motor 61 to switch the driving of the first pump head 31 or the second pump head 32. For example, when the consumable extrusion control system is applied to an electric toothbrush, the stator of the first rotary motor 61 and the first pump head 31 and the second pump head 32 are fixed on the electric toothbrush, and the rotary shaft of the first rotary motor 61 can be set to: turn it to the left to drive the first pump head 31, and turn it to the right to drive the second pump head 32; it can also be set to: turn it to the left to drive the second pump head 32, and turn it to the right to drive the first pump head 31.

[0153] Example 4

[0154] In Example 4, referring to FIG. 4A to FIG. 4B In an embodiment of the present invention, the consumable switching assembly includes:

[0155] A plurality of air bags are respectively arranged on the corresponding branch pipes 42;

[0156] A pneumatic element 71 for inflating a plurality of air bags; and

[0157] A control switch 72 for controlling the switching of the on and off states between the pneumatic element 71 and the corresponding airbag;

[0158] Among them, the consumable switching component uses the control switch 72 to connect or disconnect the pneumatic element 71 and the corresponding airbag, and realizes the switching between the disconnection and connection states between the corresponding consumable bin and the corresponding branch pipeline by utilizing the expansion and non-expansion states of the corresponding airbag.

[0159] It should be understood that the number of airbags can be multiple. In Example 4, two airbags are taken as an example. The airbags include a first airbag 73 and a second airbag 74. The first airbag 73 and the second airbag 74 are respectively arranged on corresponding branch pipes.

[0160] By inflating the pneumatic element 71, the first airbag 73 and the second airbag 74 can be switched to an expanded state; in the expanded state, the first airbag 73 and the second airbag 74 can abut against and squeeze the corresponding branch pipelines, thereby closing the corresponding branch pipelines; when the first airbag 73 and the second airbag 74 are in a contracted state, the corresponding branch pipelines are in a conducting state.

[0161] It is understandable that if Figure 4A As shown, when the first airbag 73 is in an expanded state and the second airbag 74 is in a contracted state, the branch pipeline corresponding to the second airbag 74 is connected, and the first driving component 3 can transport the consumables in the corresponding consumable bin B to the fuselage end 1. Figure 4B As shown, when the first airbag 73 is in a contracted state and the second airbag 74 is in an expanded state, the branch pipeline corresponding to the first airbag 73 is connected, and the first driving component 3 can transport the consumables in the corresponding consumable bin A to the fuselage end 1.

[0162] In the disclosed embodiment, the pneumatic element 71 may be a device such as an air pump that has a function of outputting or absorbing gas, and the control switch 72 may be a switch that has an on-off function.

[0163] Reference Figure 4A As shown, when the first airbag 73 is in the first expansion state and the second airbag 74 is in the contraction state, the control switch 72 is set to the normally closed state. At this time, the first airbag 73 will squeeze the first branch pipeline to block it, so when the first drive component 3 is working, the consumables in the consumable bin B can be sucked in or sent back.

[0164] Reference Figure 4BAs shown, the control switch 72 is set to a normally open state. For example, the control switch can be selected as a normally closed solenoid valve, and it is normally open when powered on. When the control switch 72 is in the normally open state, the pneumatic element 71 (such as the pneumatic element 71 is an air pump, the air pump motor can rotate clockwise) will pump all the gas in the first airbag 73 into the second airbag 74, and then the control switch 72 state is normally closed (such as the solenoid valve is powered off). At this time, the second airbag 74 will squeeze the second branch pipeline of the consumable bin B to block it, so the first drive component 3 will extract or push back the consumables in the consumable bin B when working. (When the motor of the air pump rotates counterclockwise, the gas in the second airbag 74 can be pumped into the first airbag 73, provided that the solenoid valve is opened to allow it to conduct). The present disclosure can achieve the purpose of switching different consumable bins by regulating the changes in the expansion state of the first airbag 73 and the second airbag 74.

[0165] Optionally, Figure 4A The solution to the residual problems in the structure shown is as follows: the first drive component 3 (such as a peristaltic pump) rotates forward for a first preset period of time to draw the consumables in the consumable bin B to the liquid outlet at the end of the body, and reverses for a second preset period of time to push the consumables remaining in the pipeline back into the consumable bin B. Figure 4B The solution to the residual in the structure shown is: work forward for a first preset time to extract the consumables in the consumable bin A to the liquid outlet at the end of the machine body, and work reversely for a second preset time to push the consumables remaining in the pipeline back to the consumable bin A.

[0166] Example 5

[0167] In another embodiment, referring to Figure 5A and Figure 5B As shown, in embodiment 5, the consumable switching assembly of the present disclosure includes:

[0168] The cam structure 8 comprises a driving motor 81 and a cam 82 rotatably connected to the driving motor 81;

[0169] The consumable switching assembly drives the cam 82 to switch between the first driving position and the second driving position through the driving motor 81, thereby realizing the switching between the on and off states between the corresponding consumable bin and the corresponding branch pipeline.

[0170] Specifically, by driving the motor 81, the cam 82 switches between the first driving position and the second driving position to control the connection or disconnection between the corresponding consumable bin 2 and the main line 41; for example, Figure 5AIn the first driving position, the cam 82 abuts against and squeezes the first branch pipeline 421, and the squeezed first branch pipeline 421 is closed, so that the pipeline between the corresponding consumable bin and the main pipeline 41 is blocked; and the second branch pipeline 422 is connected, and the pipeline between the consumable bin corresponding to the second branch pipeline 422 and the main pipeline 41 is connected; Figure 5B In the second driving position, the cam 82 abuts against and squeezes the second branch pipeline 422, and the squeezed second branch pipeline 422 is closed, so that the pipeline between the corresponding consumable bin and the main pipeline 41 is blocked; and the first branch pipeline 421 is opened, and the pipeline between the consumable bin corresponding to the first branch pipeline 421 and the main pipeline 41 is opened.

[0171] The present invention can adjust the cam 82 to squeeze the first branch pipeline 421 or squeeze the second branch pipeline 422 to achieve switching between the second conveying state or the first conveying state, thereby achieving the effect of switching different consumable bins; in the first conveying state, the consumable switching component is used to control the first branch pipeline 421 among the multiple branch pipelines to convey the first consumable; in the second conveying state, the consumable switching component is used to control the second branch pipeline 422 among the multiple branch pipelines to convey the second consumable.

[0172] Optionally, the embodiment of the present disclosure can also remove the automatic cam structure 8 and use a manually rotating cam switch. The principle is the same as that of a motor-driven cam. When the cam is manually rotated to the left, the consumables on the right will be drawn; when the cam is manually rotated to the right, the consumables on the left will be drawn.

[0173] Example 6

[0174] join Fig. 6A and Figure 6B , in Example 6, the consumable switching component is a controllable multi-way valve 9;

[0175] The controllable multi-way valve 9 includes: a first connection port 91 and at least two second connection ports 92, the first connection port 91 is connected to the main pipeline, and the second connection port 92 is connected to the branch pipelines one by one; the controllable multi-way valve 9 has a first connected state connecting the main pipeline 41 and any one of the branch pipelines 42, and a first disconnected state disconnecting the main pipeline 41 and any one of the branch pipelines 42, and the control unit is also used to control the switching of the first connected state and the first disconnected state of the controllable multi-way valve 9.

[0176] In the present embodiment of the present disclosure, by changing the connection relationship between the second connection port 92 and the first connection port 91 in the controllable multi-way valve, the connection state between the main pipeline 41 and any branch pipeline 42 can be changed according to demand, so that the consumables in the consumable bin 2 corresponding to the branch pipeline 42 can be output to the body end 1 for use, and different consumable bins 2 can accommodate different types of consumables. If the consumables are toothpaste, for example, one body end 1 can switch between multiple toothpastes according to demand to meet the user's demand for different toothpaste effects.

[0177] In the example, the first drive component 3 is a peristaltic pump; the control unit can transmit a valve control signal to the controllable multi-way valve 9 according to user needs, and transmit a pump control signal to the peristaltic pump, wherein the valve control signal is used to control the controllable multi-way valve 9 to switch the connection state between the main line 41 and any branch line 42, so that the body end 1 is connected to the target consumable bin corresponding to the consumable required by the user; the pump control signal is used to control the working state of the peristaltic pump, wherein when the peristaltic pump is in the forward state, a negative pressure is generated in the consumable bin, forcing the consumables in the consumable bin to be output to the body end 1; when the peristaltic pump is in the reverse state, the consumables on the main line and the branch line and in the controllable multi-way valve are moved back to the consumable bin to avoid mixing between different types of consumables when replacing consumables.

[0178] In the disclosed embodiment, the controllable multi-way valve 9 is a controllable three-way valve, a two-position three-way solenoid valve or a micro spiral piston switch, etc.

[0179] In this embodiment, in order to facilitate the understanding of the technology of the present disclosure, the controllable multi-way valve is illustrated when the number of consumable bins 2 is two, wherein the controllable multi-way valve 9 can be a controllable three-way valve or a two-position three-way solenoid valve. It should be noted that when the controllable multi-way valve 9 is a solenoid valve, if the consumable is toothpaste, since the toothpaste is in a gel state, the channel size in the solenoid valve is larger to facilitate the output and recovery of the toothpaste. The micro-spiral piston switch is similar to the two-position three-way solenoid valve. When powered on, the micro-spiral piston switch forms a passage to form a first connected state. When powered off, the micro-spiral piston switch forms another passage to form a second connected state. The present disclosure can switch between the first connected state and the first disconnected state by powering off or on to meet the switching of different consumable bins.

[0180] Combined with FIG. 6A to FIG. 6B As shown, in embodiment 6, the controllable multi-way valve 9 is a micro spiral piston switch. Fig. 6AWhen the micro spiral piston switch shown is not powered, the first connection port 91 of the micro spiral piston switch and the second connection port 92 connected to the first branch pipeline 421 are open, and the second connection port 92 connected to the second branch pipeline 422 is closed, so that the main pipeline 41 and the first branch pipeline 421 form a passage, and the main pipeline 41 and the second branch pipeline 422 are disconnected. When the first drive component 3 is working, the negative pressure will draw the consumables bin connected to the first branch pipeline 421. Figure 6B When the spiral plunger switch shown is energized, the first connection port 91 of the micro spiral piston switch and the second connection port 92 connected to the first branch pipeline 421 are closed, and the second connection port 92 connected to the second branch pipeline 422 is opened. The micro spiral piston switch forms a passage between the main pipeline 41 and the second branch pipeline 422, and the main pipeline 41 and the first branch pipeline 421 are disconnected. When the first drive component 3 is working, the negative pressure will draw the consumable bin connected to the second branch pipeline 422.

[0181] FIG. 6A to FIG. 6B The residual solution shown is: Fig. 6A In the embodiment, the first driving component (such as a peristaltic pump) rotates forward for a first preset time to squeeze out the consumables in the consumable bin connected to the first branch pipeline 421, and the peristaltic pump rotates reversely for a second preset time to push the consumables in the first branch pipeline 421 and the main pipeline 41 back to the consumable bin connected to the first branch pipeline 421. Figure 6B In the process, the peristaltic pump rotates forward for a first preset time to squeeze out the consumables in the consumable bin connected to the second branch pipeline 422, and the peristaltic pump rotates reversely for a second preset time to push the consumables in the pipeline back to the consumable bin connected to the second branch pipeline 422.

[0182] Optionally, in the present disclosure, the controllable multi-way valve 9 can also be set as a manually switched consumable: the driving motor inside the controllable multi-way valve 9 is removed and replaced with a manually toggled switch. The specific working principle is the same as the automatic switching, and will not be repeated here.

[0183] In another possible implementation, when the controllable multi-way valve is a two-position three-way solenoid valve, its residual solution is the same as that of the above-mentioned micro spiral piston switch, and will not be repeated here.

[0184] Example 7

[0185] The first drive assembly 3 in the embodiment of the present disclosure can be flexibly arranged. In one implementation, the first drive assembly 3 is arranged at one end close to the fuselage end 1, the first connection port 91 of the controllable multi-way valve 9 is connected to the main pipeline 41 close to the fuselage end 1, and the second connection port 92 is connected to the branch pipeline 42 connected to the consumables bin, such as Fig. 6A and Figure 6BAs shown; however, in Example 7, the first drive assembly 3 is arranged at an end away from the body end 1, and the first drive assembly 3 is connected to multiple consumable bins.

[0186] Here, the first driving component 3 is exemplified as a rotary pump, and the switching between the first driving state and the second driving state is achieved by the forward and reverse rotation of the rotary pump.

[0187] It is also worth mentioning that the position of the controllable multi-way valve 9 can also be flexibly set, and can refer to Fig. 7A Alternatively, you can refer to the position shown in the two-position three-way solenoid valve Figure 8 The position shown in the two-position three-way solenoid valve is not limited in this disclosure.

[0188] Specifically, refer to 7A to 7C As shown, in Example 7, the consumable switching component is a controllable multi-way valve 9, which is arranged on the main line 41 close to the fuselage end 1, and the first driving component 3 is an air pump component 13, which is arranged at an end away from the fuselage end 1 and is connected to multiple consumable bins 2.

[0189] Furthermore, if Figure 7B and Figure 7C As shown, the first driving component 3 is connected to a plurality of consumable bins 2 through a first common pipeline 10, and the first driving component 3 is an air pump component, and the air pump component includes:

[0190] A second common pipeline 11 connected to the first common pipeline 10;

[0191] A third common pipe 12 connected to the second common pipe 11;

[0192] The fourth pipeline 14 and the fifth pipeline 15 are respectively connected to two ends of the third common pipeline 12;

[0193] An air pump assembly 13, the air pump assembly 13 comprising an air inlet 131 and an air outlet 132 respectively connected to the fourth pipeline 14 and the fifth pipeline 15;

[0194] The solenoid valve assembly 16 includes a first solenoid valve 161 and a fourth solenoid valve 164 arranged on the third common pipeline 12, a third solenoid valve 163 arranged on the fourth pipeline 14, and a second solenoid valve 162 arranged on the fifth pipeline 15; the first solenoid valve 161, the second solenoid valve 162, the third solenoid valve 163 and the fourth solenoid valve 164 are normally open solenoid valves or normally closed solenoid valves;

[0195] Among them, the control unit is also used to selectively control the opening and closing states of the first solenoid valve 161, the second solenoid valve 162, the third solenoid valve 163 and the fourth solenoid valve 164 of the solenoid valve assembly 16 based on the first driving state and the second driving state of the air pump assembly 13.

[0196] For example, it is assumed that the first solenoid valve 161, the second solenoid valve 162, the third solenoid valve 163 and the fourth solenoid valve 164 of the solenoid valve assembly 16 are all in a normally closed state when not powered, that is, they are all normally closed solenoid valves. Figure 7B As shown in the state of positive pressure pushing consumables, the control unit controls the first solenoid valve 161 and the third solenoid valve 163 to be energized, and the second solenoid valve 162 and the fourth solenoid valve 164 to maintain a closed state, so that the fourth pipeline 14 is closed and the fifth pipeline 15 is connected, and the air pump assembly 13 can push out the consumables with positive pressure.

[0197] Reference Figure 7C In the negative pressure residual extraction state shown, the control unit controls the second solenoid valve 162 and the fourth solenoid valve 164 to be energized, and the first solenoid valve 161 and the third solenoid valve 163 remain in a closed state, so that the fourth pipeline 14 is connected and the fifth pipeline is closed, and the air pump assembly 13 can use negative pressure to extract the residual consumables in the pipeline.

[0198] In implementation 7, the consumable pipelines corresponding to different consumable bins can be switched through the controllable multi-way valve 9, and the cooperation of the air pump assembly 13 and the solenoid valve assembly 16 can achieve positive pressure to push out the consumables and negative pressure to draw back the consumables, thereby avoiding the problem of consumable residue.

[0199] Example 8

[0200] like Figure 8 As shown, in embodiment 8, the present disclosure can also arrange the controllable multi-way valve 9 and the first drive assembly at an end away from the fuselage end 1. For example, Figure 8 The first driving assembly 3 shown is a pneumatic device, such as an air pump, etc. The controllable multi-way valve 9 can be a controllable three-way valve or a two-position three-way solenoid valve, a micro spiral piston switch, etc.

[0201] In general, in all the above schemes, the consumable switching assembly actually constitutes a valve group switch for switching the consumable pipeline, which is used to control the switching selection of the corresponding consumable pipeline. Except for the different structures of the consumable switching assembly in Examples 2 to 8, the other structures are the same, and the difference from Examples 2 to 6 is that the first drive assembly 3 of Examples 7 and 8 is set at an end away from the fuselage end. Figure 1 The solution of the embodiment 1 shown is to independently control the consumable extrusion of the corresponding consumable bin by setting up separate pipelines and power equipment.

[0202] It should be understood that in the above scheme, the peristaltic pump and the air pump can be replaced by a rotary pump such as a gear pump, a screw pump, or a rotor pump. When a rotary pump is used, the positive and negative pressures of the rotary pump can be used to solve the problem of consumables remaining in the pipeline. When an air pump is used, the positive and negative pressures of the air pump can be used to solve the problem of consumables remaining in the pipeline.

[0203] It should be understood that the at least two consumable bins in the above scheme may be two separate consumable bins or two bins of a tank body, and the tank body may be a consumable tank, that is, it may contain consumables such as toothpaste, mouthwash, cleaning liquid, facial cleanser, skin care products, etc., and the present disclosure does not impose any restrictions on this.

[0204] Through the consumable extrusion control system disclosed in the present invention, consumables with different flavors and / or different functions can be provided to users to meet the various usage needs of users. Taking toothpaste as an example, according to the taste classification, toothpastes with different flavors include strawberry, yellow peach, peach, crisp peach, green grape, lemon, watermelon, apple, grapefruit, sea salt, milk ice cream, chocolate ice cream, grape, pineapple, orange, blueberry, bayberry, star fruit, osmanthus, rose, jasmine, magnolia and other flavors; according to the function classification, toothpastes with different functions include toothpastes for removing tooth stains, clearing breath, protecting gums, preventing tooth decay, whitening, anti-irritation, removing smoke stains, reducing internal heat, children's special, pregnant women special and other flavors.

[0205] Through the consumable extrusion control system disclosed in the present invention, suitable care plans can also be provided to users. For example, taking the tooth care process as an example: a tank body can include four consumable bins, and the four consumable bins are respectively filled with stain removing toothpaste, polishing agent, repairing agent, and whitening toothpaste. By switching and controlling the corresponding consumable bins in turn, the process of stain removing → polishing → repairing → whitening can be achieved, allowing users to complete a complete set of tooth care processes at home through personal operations.

[0206] For instance, taking skin care as an example: a tank body may include six consumables bins, which are respectively filled with makeup removal or cleansing materials, toner, essence, eye cream, lotion, face cream, and sunscreen. By switching and controlling the corresponding consumables bins in sequence, the following process can be achieved: makeup removal or cleansing → applying toner → applying essence → applying eye cream → applying lotion → applying face cream → applying sunscreen. This allows users to complete a complete skin care process at home through personal operations.

[0207] The consumable extrusion control system provided by the present disclosure can provide users with different types of consumables with different flavors, different colors, different functions, etc., to meet the various usage needs of users. Moreover, through the consumable extrusion control system provided by the present disclosure, combined with the corresponding switching control program, the consumable extrusion sequence process can be customized according to user needs to meet the user's personal care needs.

[0208] The consumable extrusion control system provided by the present disclosure adopts a rotary pump to provide power for consumable transportation, and can use the forward and reverse suction of the rotary pump to solve the problem of consumable residue in the pipeline, so as to avoid mixing of different types of consumables and affecting user experience.

[0209] The following is combined with Figures 1 to 9 As shown, the consumable extrusion control method applied to the consumable extrusion control system provided by the embodiment of the present disclosure is described in detail through specific embodiments and their application scenarios.

[0210] Reference Fig. 9 As shown, the consumable extrusion control method of the embodiment of the present disclosure is applied to Figures 1 to 8 The consumable extrusion control system described in the invention comprises:

[0211] Step 171, inputting a first signal to the first driving component to put the first driving component in the first driving state;

[0212] Step 172: input a second signal to the first driving component to put the first driving component in the second driving state.

[0213] In the embodiment of the present disclosure, by inputting a first signal to the first drive component, the first drive component is placed in a first drive state. In the first drive state, the first drive component is used to convey the consumables in the corresponding consumable bin 2 to the body end 1. Since there are at least two consumable bins, it is possible to automatically switch and extrude two or more consumables in one product to achieve the versatility of different consumables for oral cleaning and meet more user usage requirements. On the other hand, by inputting a second signal to the first drive component, the first drive component is placed in a second drive state. In the second drive state, the first drive component is used to move the consumables in the main pipeline and the branch pipeline back to the corresponding consumable bins. This can solve the problem of residual consumables in the common pipeline during the previous consumable extrusion, causing pipeline blockage, and mixing of two or more consumables during the next consumable extrusion when multiple consumables are switched.

[0214] For example, in one application scenario, step 171 may be implemented first, and then step 172 may be implemented, so as to push the consumables to the body end first, and then extract the consumables in the pipeline back to the consumable bin.

[0215] Optionally, the first driving component is a rotary pump, and the consumable extrusion control method disclosed in the present invention further includes:

[0216] According to the first signal, controlling the first driving component to rotate forward for a first preset time period in the first driving state;

[0217] According to the second signal, controlling the first driving component to reverse for a second preset time length in the second driving state;

[0218] The first preset duration and the second preset duration are determined according to preset factors; the preset factors include at least one of the following:

[0219] a target amount of consumables discharged from one of the plurality of consumable bins;

[0220] The diameter and length of the main pipeline and the branch pipeline;

[0221] The rotational speed of the rotary pump.

[0222] In the embodiment of the present disclosure, when the first drive component includes a rotary pump, the first drive component is controlled to rotate forward for a first preset time or reverse for a second preset time according to the first signal or the second signal, so that the first drive component can be switched between the first drive state and the second drive state. Taking the rotary pump as a peristaltic pump as an example, the peristaltic pump is first controlled to rotate forward for a first preset time by the first signal, and then the peristaltic pump is controlled to reverse for a second preset time by the second signal. When the next consumable is extruded, it is also first rotated forward for a first preset time, and then reversed for a second preset time. In this way, it can be avoided that the previous consumable remains in the pipeline and blocks the pipeline and contaminates the next consumable.

[0223] The first preset duration and the second preset duration of the present disclosure are determined according to at least one of the preset factors; the preset factors include at least one of the following: the target amount of consumables discharged from one of the at least two consumable bins; the diameter and length of the main pipeline and the branch pipeline; the rotation speed of the rotary pump. The preset factors of the present disclosure can also be other factors that affect the input or output power of the first drive component. Of course, the first preset duration and the second preset duration of the present disclosure can also be configured or pre-configured values. For example, when the consumable is toothpaste, the first preset duration is 3 to 5 seconds to ensure that 0.4 to 1.2g of toothpaste is pushed out, and the second preset duration is 1 to 3S; that is, in other embodiments, the first preset duration can also be other values, and the present disclosure does not limit this.

[0224] It is also worth mentioning that a one-way valve can be provided at the liquid outlet position of the body end, so that when the rotary pump reverses to extract the remaining consumables in the corresponding pipeline, the end of the pipeline will preferentially absorb air, so that when the rotary pump reverses, the excess consumables in the pipeline will be sucked back into the corresponding consumable bin, thereby avoiding sucking the squeezed consumables into the consumable bin as much as possible.

[0225] Optionally, the first driving component is a rotary pump, and the consumable extrusion control method disclosed in the present invention further includes:

[0226] When the rotary pump rotates forward, obtaining a target consumable material delivery amount detected by a flow sensor disposed on the main pipe;

[0227] When the target consumable delivery amount meets the preset delivery amount, outputting a third signal to the rotary pump;

[0228] According to the third signal, the rotary pump stops forward rotation and controls the rotary pump to switch to reverse rotation;

[0229] When the rotary pump reverses, the flow sensor detects that the consumables extracted from the pipeline are zero, and then stops reversing.

[0230] In the disclosed embodiment, a flow sensor is provided in the consumable extrusion control system, and the flow sensor is used to detect the amount of consumables delivered by the peristaltic pump. After the peristaltic pump rotates forward until the amount of consumables detected by the flow sensor reaches a preset delivery amount (configured or preconfigured target value), the peristaltic pump reverses until the flow rate of the consumables detected by the flow sensor is zero, and then stops reversing, so as to avoid consumables remaining in the pipeline. It can be understood that the amount of consumables delivered by the rotary pump is detected by the flow sensor, and after the rotary pump rotates forward until the amount of consumables detected by the flow sensor reaches the target value, the rotary pump reverses until the flow rate of the consumables detected by the flow sensor is zero, and then stops reversing.

[0231] Preferably, the flow sensor is arranged on the main pipe in the consumable extrusion control system.

[0232] Optionally, the target value of the preset delivery amount setting may be 0.4 g to 1.2 g.

[0235] Inputting a fifth signal to the first driving assembly so that the first solenoid valve and the third solenoid valve of the air pump assembly are in a closed state, and the second solenoid valve and the fourth solenoid valve of the air pump assembly are in an open state;

Figure 7B In the state of positive pressure pushing consumables shown, the control unit controls the first solenoid valve 161 and the third solenoid valve 163 to be energized, and the second solenoid valve 162 and the fourth solenoid valve 164 remain in a closed state, so that the fourth pipeline 14 is closed and the fifth pipeline 15 is connected, and the air pump assembly 13 can push out the consumables with positive pressure.

[0238] Input a fifth signal to the air pump assembly to control the first drive assembly to be in the second drive state, for example, refer to Figure 7C In the state of negative pressure pushing the consumables shown, the control unit controls the second solenoid valve 162 and the fourth solenoid valve 164 to be energized, and the first solenoid valve 161 and the third solenoid valve 163 remain in a closed state, so that the fourth pipeline 14 is connected and the fifth pipeline is closed. That is, the air pump will extract the gas in the consumable bin to form a negative pressure in the consumable bin, and the consumables inside the pipeline can be pumped out at this time.
