Description

cosmetic dispenser

This disclosure relates to a cosmetic dispenser.

Recently, the needs of users who want to receive customized cosmetics and hair dyes have been increasing. For example, the need to be provided with cosmetics appropriate for the user's current skin condition at any time, or the need to be provided with a hair dye that takes into account the user's current hair color and condition in order to dye the user's hair to a desired color, is increasing.

Accordingly, devices that measure the user's condition and provide cosmetics or dyes by combining various cosmetics according to the measured user's condition are being developed.

Meanwhile, since these devices mix various cosmetics according to the user's condition, a method is required to precisely discharge each cosmetic in a predetermined amount. In addition, if it takes an excessively long time to dispense cosmetics, it causes user inconvenience, so a method to shorten the time required to dispense cosmetics during precise dispensing is also required.

The present disclosure seeks to provide a cosmetic dispenser that precisely dispenses cosmetics at a target discharge amount.

The present disclosure seeks to provide a cosmetic dispenser that minimizes the time required to dispense cosmetics.

The present disclosure seeks to provide a cosmetic dispenser that accurately calculates the amount of cosmetic remaining in the cartridge.

A cosmetic dispenser according to an embodiment of the present disclosure includes a plurality of cartridges containing cosmetics inside and a head through which pressure is applied to discharge the cosmetics, a pusher that presses the head of one of the plurality of cartridges, and a pusher. It includes a controller that raises or lowers the head, and a first sensor that detects the size of the load when the head is pressed. The first sensor may be installed in the pusher.

The controller may obtain the state of the pusher, including whether the head is pressed, through the first sensor.

If no load is detected by the first sensor, the controller acquires the pusher as being in a first state in which the head is not being pressed, and if a load is detected by the first sensor, the pusher can be acquired as being in a second state in which the head is being pressed. there is.

The controller may control the rising speed of the pusher to the first speed when the pusher is in the first state, and may control the rising speed of the pusher to the second speed when the pusher changes from the first state to the second state.

The first speed may be faster than the second speed.

The controller may obtain the discharge amount of cosmetics discharged from the cartridge while the pusher is in the second state through the first sensor.

The controller can control the rising speed of the pusher to a third speed when the discharge amount reaches a preset reference amount.

The second speed may be faster than the third speed.

The controller can lower the pusher when the discharge amount reaches the target discharge amount.

The controller may obtain the discharge amount from the cartridge based on the load size detected by the first sensor.

The controller may obtain the remaining amount of cosmetics remaining in the cartridge based on the load size detected by the first sensor.

The controller can adjust the rising speed of the pusher based on the remaining amount of cosmetics.

It may further include a second sensor that detects the weight of the cosmetic discharged from the cartridge, and the second sensor may be installed below the receiving body where the container receiving the discharged cosmetic is placed.

The first sensor can obtain the discharge amount through the load size detected by the cartridge when discharging the cosmetic, and the second sensor can obtain the discharge amount through the size of the load sensed by the receiving body when discharging the cosmetic.

The pusher rises at a first speed until it touches the cartridge, rises at a second speed slower than the first speed immediately after touching the cartridge, and rises at a third speed slower than the second speed when the amount of cosmetic discharged from the cartridge is more than a preset standard amount. It rises, and can fall when the cosmetic discharge amount reaches the target amount.

According to an embodiment of the present disclosure, the discharge amount of cosmetics is obtained based on the load of the cartridge, so that it is possible to detect whether discharge is complete before all the cosmetics are contained in the container. Accordingly, when the weight contained in the container reaches the target discharge amount When a command to stop discharging is given, the target discharge amount is discharged, which has the advantage of minimizing the problem of errors occurring due to the cosmetics remaining in the discharge port falling even after receiving the command to stop discharging.

According to an embodiment of the present disclosure, it is possible to detect whether the discharge of cosmetics has started through a sensor installed in the discharge module for discharging the cosmetics, and the discharge module can be operated more quickly before discharge starts, thereby reducing the time required to discharge the cosmetics. There is an advantage in that it can be shortened.

According to an embodiment of the present disclosure, it is possible to obtain the amount of cosmetic remaining in the cartridge by considering not only the amount of cosmetic discharged from each cartridge but also the load of each cartridge, so there is an advantage in that the replacement time of the cartridge can be detected more accurately.

The cosmetic dispenser 1 includes a housing 10, and various components including a cartridge 5 (see FIG. 3) may be placed inside the housing 10. A display 6 may be installed on one side of the housing 10, and the display 6 may output various information related to the operation of the cosmetic dispenser 1. Additionally, the display 6 may be implemented as a touch screen to receive user input.

Additionally, a discharge hole 9 may be formed in the housing 10 so that a container containing cosmetics (8, see FIG. 3) can be placed in and out of the housing 10. The user can place the container 8 inside the housing 10 or remove it through the discharge hole 9.

On the other hand, since cosmetics are directly contained in the container 8, problems may arise where it is difficult to remove contamination due to continuous use. Accordingly, the container 8 can be loaded in and out of the housing 10 while being contained in a separate receiving body 7 (see FIG. 2). The container 8 can be separated from the receiving body (see Figure 2 7).

Next, with reference to FIGS. 2 and 3 , the internal configuration of the housing 10 including the receiving body 7 will be described.

FIG. 2 is a diagram illustrating a component installed inside a housing according to an embodiment of the present disclosure separately, and FIG. 3 is a view of a component installed inside the housing according to an embodiment of the present disclosure as viewed from the side.

In the housing 10, a frame 20, a rotatable main body 21 installed on the frame 20, and a discharge module 60 that discharges cosmetics from the cartridge 5 mounted on the main body 21 are disposed. You can.

A supporter 22 may be formed on the frame 20 to support the main body 21. The supporter 22 may support the main body 21 so that the main body 21 can rotate.

The discharge module 60 may be fixed to the frame 20. The discharge module 60 will be described in detail in FIGS. 4 and 5.

Meanwhile, the discharge module 60 can discharge the cosmetic material filled in the cartridge 5 to the outside, and the cosmetic material discharged from the cartridge 5 can be contained in the container 8.

Cartridge 5 may be mounted on the main body 21. A plurality of holes in which each of the plurality of cartridges 5 can be placed may be formed in the main body 21. Each of the plurality of cartridges 5 may contain cosmetics therein.

The container 8 may be placed inside the housing 10 while placed on the receiving body 7.

Meanwhile, the cosmetic dispenser 1 according to an embodiment of the present disclosure may include at least one

sensor

105 or 106 for obtaining the discharge amount of cosmetics discharged from the cartridge 5.

Specifically, the cosmetic dispenser 1 includes a first sensor 105 that obtains the cosmetic discharge amount based on the load of the cartridge 5 when discharging the cosmetic, and a second sensor 105 that obtains the cosmetic discharge amount by directly detecting the weight of the container 8. It may include at least one of the sensors 106.

The first sensor 105 may be installed in the discharge module 60, and the second sensor 106 may be installed under the receiving body 7 or the area in the housing 10 where the receiving body 7 is located. You can. That is, the second sensor 106 may be disposed in the receiving body 7 or below the receiving body 7.

Next, with reference to FIGS. 4 and 5 , the discharge module 60 and the first sensor 105 installed thereon will be described.

FIG. 4 is a perspective view showing a discharge module according to an embodiment of the present disclosure, and FIG. 5 is a view showing a discharge module, a cartridge, and a container according to an embodiment of the present disclosure.

The discharge module 60 may be a module for discharging the cosmetic contained in the cartridge 5.

The discharge module 60 includes a pusher 61 that presses the head 54 of the cartridge 5, a base 65 that supports the pusher 61, a pusher cover 67 that covers a part of the pusher 61, and a pusher 61. It may include at least part or all of the lifting motor 64 that raises or lowers (61).

The pusher 61 can apply pressure to the head 54 of the cartridge 5. For example, while the cartridge 5 is fixed, the pusher 61 may press the head 54 as it rises toward the head 54 . When the pusher 61 rises, its upper surface comes into contact with the head 54 and can pressurize the head 54 as it continues to rise while its upper surface is in contact with the head 54.

A pusher 54 and a nozzle 55 may be formed in the cartridge 5. The cartridge 5 may be a container in which the cosmetic contained therein is discharged through the nozzle 55 when pressure is applied to the pusher 54. Accordingly, a head 54 through which pressure is applied to discharge the cosmetic may be formed on each of the plurality of cartridges 5. The pusher 61 can press the head 54 of one of the plurality of cartridges 5.

The pusher 61 may be composed of a support portion 62 fixed to the base 65 and a pressing portion 63 extending from the support portion 62 to form a contact surface contacting the head 54, and the contact surface is the pressing portion 63. It may be the upper surface of . The support part 62 may have one end fixed to the base 65 and the other end extending to the pressing part 63. The support portion 62 may be fixed to the base 65 by a fastening member (not shown). Additionally, a portion of the support portion 62 may be accommodated in the pusher cover 67.

The lower end of the pusher cover 67 is fixed to the base 65, and a long opening (not shown) is formed on one side in the height direction, so that the pusher 61 can move up and down along the opening. The pusher cover 67 can guide the raising and lowering of the pusher 61. In particular, the pusher cover 67 may limit the maximum height at which the pusher 61 can move.

A first sensor 105 may be installed inside the support portion 62. Meanwhile, in FIGS. 4 and 5, the first sensor 105 is shown as being installed on the support part 62, but this is only an example and may be installed on the pressing part 63. That is, the first sensor 105 may be installed on the pusher.

The first sensor 105 may be a load cell, but this is only an example and the first sensor 105 may include any type of sensor capable of measuring load.

The lifting motor 64 can raise or lower the head 61. 4 and 5, the lifting motor 64 is shown as installed at the lower part of the base 65, but it is reasonable that the position of the lifting motor 64 is not limited.

The lifting motor 64 can raise the pusher 61 when discharging cosmetics from the cartridge 5. When the pusher 61 is raised by the lifting motor 64 and applies pressure to the head 54 while contacting the head 54, the cosmetic contained in the cartridge 5 can be discharged to the outside through the nozzle 55. . Cosmetic discharged through the nozzle 55 can be contained in the container 8.

Meanwhile, the cosmetic dispenser 1 according to an embodiment of the present disclosure can control the pusher 61 based on the discharge information of the cosmetic obtained through the first sensor 105 in order to more quickly and accurately discharge the cosmetic. There is, and this will be described later.

FIG. 6 is a control block diagram of a cosmetic dispenser according to an embodiment of the present disclosure, FIG. 7 is a flowchart showing a method of operating a cosmetic dispenser according to an embodiment of the present disclosure, and FIG. 8 is a specification of step S20 of FIG. 7. This is a flowchart.

The cosmetic dispenser 1 may include at least part or all of the first sensor 105, the second sensor 106, the main motor 50, the lifting motor 64, and the controller 170. Meanwhile, FIG. 6 shows only some configurations for explaining the operation method according to FIGS. 7 and 8, and the cosmetic dispenser 1 may further include other configurations other than those shown in FIG. 6.

The first sensor 105 is installed on the pusher 61 and can detect the load on the cartridge 5 while the pusher 61 applies pressure to the head 54. The first sensor 105 may be a load or a discharge load of the cartridge 5, and the load of the cartridge 5 and the discharge load may be the same concept.

The first sensor 105 may be a load cell and may obtain an electrical output signal proportional to the size of the load. The first sensor 105 can detect the size of the load when the head 54 is pressed. For example, the controller 170 may store in advance data mapping the discharge amount per hour according to the size of the load, and detect the size of the load detected by the first sensor 105 to detect the size of the load (load) in the cartridge 5. The discharge amount of the discharged cosmetic product can be obtained. That is, the first sensor 105 can detect the pressing force (mgf), that is, the size of the load (load), for each cartridge 5 and obtain the discharge amount (mg).

The second sensor 106 may be installed below the receiving body 7 or the receiving body 7 where the container 8 containing the cosmetic discharged from the cartridge 5 is disposed. However, the position of the second sensor 106 described above is only an example, and the second sensor 106 may be installed in a position where the weight of the container 8 containing the cosmetic discharged from the cartridge 5 can be measured. there is.

The main motor 50 can rotate a plurality of cartridges 5. The main motor 50 may rotate the main body 21 on which the plurality of cartridges 5 are arranged so that one cartridge 5 to be discharged is located in the discharge area.

The lifting motor 64 can adjust the height of the pusher 61. The lifting motor 64 can raise, lower, or stop the pusher 61.

The controller 170 may control the first sensor 105, the second sensor 106, the main motor 50, and the lifting motor 64. The controller 170 can control each component provided in the cosmetic dispenser 1. The controller 170 can control the operation of the cosmetic dispenser 1. The controller 170 may raise or lower the pusher 61 so that the cosmetic is discharged.

Additionally, the controller 170 may obtain the remaining amount of cosmetic product for each cartridge 5 and output a cartridge replacement alarm when the remaining amount is less than a preset threshold. For example, the controller 170 may transmit a cartridge replacement alarm to a user terminal (not shown) through wireless communication when the remaining amount is less than a preset threshold.

Meanwhile, according to one embodiment, the controller 170 may obtain the remaining amount by subtracting the discharge amount according to discharge information from the remaining amount obtained just before.

According to another embodiment, the controller 170 may obtain the remaining amount by subtracting the discharge weight detected by the second sensor 106 from the remaining amount obtained just before.

According to another embodiment, the controller 170 may obtain the remaining amount of the cartridge by storing the load size of the cartridge 5 when discharging cosmetics. Specifically, the cartridge 5 is a pressure container, and as the contents are discharged, the internal pressure decreases, and this internal pressure is a factor directly related to the load for discharging the cosmetic. For example, as the remaining amount of cartridge accommodated in the cartridge 5 decreases, the size of the load detected through the first sensor 105 when discharging the corresponding cartridge 5 may decrease. Accordingly, the controller 170 stores the load size for each cartridge 5 each time it is ejected, so that the remaining amount of the cartridge 5 can be obtained through changes in the load size.

Additionally, the controller 170 may adjust the rising speed of the pusher based on the load size of the corresponding cartridge 5 immediately before discharging the cosmetic. That is, the controller 170 may finely adjust the rising speed of the pusher 61 so that the cosmetic discharge amount is constant.

Next, a method by which the controller 170 controls the discharge of cosmetics will be described.

Referring to FIG. 7, the controller 170 can obtain discharge information (S10).

The discharge information may be information about the type and weight of the cosmetic to be discharged, or information about the type and discharge amount of the cartridge to be discharged. For example, the controller 170 may obtain discharge information in the form of 5g of the first cosmetic, 10g of the second cosmetic, or 5g from the first cartridge and 10g from the second cartridge.

The controller 170 can discharge the cosmetic for each cartridge according to the discharge information (S20) and determine whether the discharge of the cosmetic is complete according to the discharge information (S30).

If the discharge of the cosmetic material is not complete, the controller 170 may discharge the cosmetic material that has not yet been discharged based on the discharge information. The controller 170 may end the dispensing operation when the dispensing of the cosmetic material is completed.

Next, the method by which the controller 170 discharges cosmetics for each cartridge according to discharge information will be described in detail with reference to FIG. 8.

Referring to FIG. 8, the controller 170 can move any one cartridge to be discharged to the discharge area (S201).

Specifically, the controller 170 may control the main motor 50 so that one of at least one cartridge to discharge cosmetics moves to the discharge area according to discharge information.

The discharge area may refer to an area that overlaps the container 8 in the vertical direction.

When the cartridge 5 to be discharged is located in the discharge area, the controller 170 may raise the pusher 61 at a first speed (S203).

The first speed may be a value between 20 and 30 mm/s, but since this is only an example, it is reasonable that it is not limited thereto.

The controller 170 may obtain whether the first sensor 105 detects a load while raising the pusher 61 at the first speed (S205).

Specifically, the controller 170 may obtain whether the first sensor 105 detects a load while raising the pusher 61 at the first speed. When the pusher 61 is not in contact with any component, the magnitude of the load detected by the first sensor 105 installed on the pusher 61 may be 0. Meanwhile, the magnitude of the load detected by the first sensor 105 from the moment the pusher 61 touches the head 54 as it rises may exceed 0.

If the magnitude of the load obtained by the first sensor 105 exceeds 0, the controller 170 may determine that the load has been detected. Since the size of the load exceeds 0 from the moment the pusher 61 touches the head 54 while rising, the controller 170 moves the pusher 61 to the head 54 when the first sensor 105 detects the load. It can be judged that it has reached .

Through this, the controller 170 can move the pusher 61 at the first speed until the pusher 61 contacts the head 54. That is, the point in time when the pusher 61 contacts the head 54 can be detected through the first sensor 105 installed on the pusher 61, and the pusher 61 moves until the pusher 61 touches the head 54. ) has the advantage of being able to increase at a relatively rapid rate. Accordingly, the pusher 61 can be moved at high speed until it touches the head 54, rather than at a predetermined height before it touches the head 54, which has the advantage of shortening the time required to discharge cosmetics. That is, since the pusher 61 operates minutely from the time the pusher 61 comes into contact with the head 54, the time required to discharge cosmetics can be shortened. Accordingly, there is an advantage in improving the problem of increasing the waiting time for the user to receive cosmetics by slightly moving the pusher 61 without knowing when the cosmetics will be discharged.

When the first sensor 105 detects a load, the controller 170 can change the speed of the pusher 61 to the second speed (S207).

That is, the controller 170 can adjust the rising speed of the pusher 61 to the second speed when the first sensor 105 detects a load. That is, the controller 170 can raise the pusher 61 at the second speed.

At this time, the second speed may be slower than the above-described first speed. That is, the first speed may be faster than the second speed. The controller 170 may adjust the speed of the pusher 61 to be slower than the speed in step S203. The second speed may be a value between about 0 and 10 mm/s, but since this is only an example, it is reasonable that it is not limited thereto.

The controller 170 may raise the pusher 61 at the second speed and discharge the cosmetic contained in the cartridge 5 to the outside.

The controller 170 may obtain the discharge amount while raising the pusher 61 at the second speed (S209).

According to one embodiment, the controller 170 may obtain the discharge amount of cosmetics discharged from the cartridge 5 through the first sensor 105. The discharge amount may be the weight of the discharged cosmetic.

Even if the rising speed of the pusher 61 is the same, the larger the amount of cosmetic contained in the cartridge 5, the larger the discharge amount from the cartridge 5, and accordingly, the size of the load detected by the first sensor 105 is larger. Likewise, even if the rising speed of the pusher 61 is the same, the smaller the amount of cosmetic contained in the cartridge 5, the smaller the discharge amount from the cartridge 5, and accordingly, the load detected by the first sensor 105 is lower. It is small in size.

Accordingly, the controller 170 can calculate the discharge amount from the cartridge 5 based on the size of the load detected by the first sensor 105.

In this way, when obtaining the discharge amount through the first sensor 105, there is an advantage of being able to immediately detect the discharge amount that changes in real time through the size of the load. In addition, when the discharge amount is detected by directly detecting the weight of the container (8), even though the target discharge amount has already been discharged from the cartridge (5), the container (8) contains cosmetics and the weight of the container (8) is calculated to have reached the target discharge amount. There is a problem in that more cosmetics are discharged from the cartridge 5 in the meantime, exceeding the target discharge amount. However, when the discharge amount is obtained through the first sensor 105, the discharge amount can be obtained before being placed in the container 8. There is an advantage in that the above-mentioned problem can be improved. That is, when the discharge amount of the cartridge 5 obtained through the first sensor 105 reaches the target discharge amount, the controller 170 lowers the pusher 61 to stop discharge, thereby solving the problem of discharge exceeding the target discharge amount. There are benefits that can be improved.

The controller 170 may obtain whether the discharge amount reaches a preset reference amount (S211).

In order to shorten the cosmetic discharge time, the standard amount is discharged in relatively large amounts, and when the standard amount is exceeded, the speed of the pusher 61 can be adjusted to discharge a relatively adaptive amount to solve the problem of discharge exceeding the target discharge amount, that is, to improve accuracy.

Accordingly, the controller 170 may determine whether the discharge amount has reached a preset reference amount while raising the pusher 61 at the second speed. At this time, the reference amount may be 90% of the target discharge amount, but this is only an example. The standard amount may be a value obtained by subtracting a specific weight (about 2g) from the target discharge amount.

When the discharge amount reaches a preset reference amount, the controller 170 may change the speed of the pusher 61 to the third speed (S213).

That is, the controller 170 may adjust the rising speed of the pusher 61 to the third speed when the discharge amount reaches a preset reference amount. That is, the controller 170 can raise the pusher 61 at the third speed.

At this time, the third speed may be slower than the above-described second speed. That is, the second speed may be faster than the third speed. The controller 170 may adjust the speed of the pusher 61 to be slower than the speed in step S207. The third speed may be a value between about 0 and 5 mm/s, but since this is only an example, it is reasonable that it is not limited thereto.

When the discharge amount reaches a preset standard amount, the controller 170 reduces the upward speed of the pusher 61 to reduce the discharge amount per hour, thereby finely controlling the discharge amount.

The controller 170 obtains the discharge amount while raising the pusher 61 at the third speed, and can obtain whether the discharge amount reaches the target amount (S215).

The target amount may mean the target discharge amount desired to be discharged from the corresponding cartridge according to the discharge information.

If the discharge amount does not reach the target amount, the controller 170 may continue to raise the pusher 61 at the third speed. Meanwhile, when the discharge amount reaches the target amount, the controller 170 can obtain whether discharge is complete for all cartridges subject to discharge (S217).

If ejection has not been completed for all cartridges subject to ejection, the controller 170 may move the next cartridge to the ejection area. The controller 170 may end the ejection operation when ejection of all cartridges subject to ejection is completed.

In summary, the controller 170 obtains the state of the pusher 61, including whether the head 54 is pressed, through the first sensor 105, and when no load is detected by the first sensor 105 The pusher 61 is acquired as being in a first state in which the head 54 is not being pressed, and when a load is detected by the first sensor 105, the pusher 61 is acquired as being in a second state in which the head 54 is being pressed. It can be obtained. The controller 170 controls the rising speed of the pusher 61 at the first speed when the pusher 61 is in the first state, and when the pusher 61 changes from the first state to the second state, the The rising speed is controlled to a second speed, and at this time, the first speed may be faster than the second speed. The controller 170 acquires the discharge amount of cosmetics discharged from the cartridge 5 while the pusher 61 is in the second state through the first sensor 105, and when the discharge amount reaches a preset reference amount, the pusher 61 The rising speed is controlled to a third speed, and at this time, the second speed may be faster than the third speed. When the discharge amount reaches the target discharge amount, the controller 170 may lower the pusher 61 to stop discharge. That is, the pusher 61 rises at a first speed until it touches the cartridge 5, and immediately after touching the cartridge 5, it rises at a second speed slower than the first speed, and the amount of cosmetic discharged from the cartridge 5 If it is more than the preset standard amount, it may rise at a third speed that is slower than the second speed, and may fall when the cosmetic discharge amount reaches the target amount.

Meanwhile, the controller 170 may obtain the discharge amount from the cartridge 5 based on the load size detected by the first sensor 105. Additionally, the controller 170 may obtain the remaining amount of cosmetics remaining in the cartridge 5 based on the load size detected by the first sensor 105, and adjust the rising speed of the pusher 61 based on the remaining amount of cosmetics. You can also adjust it.

Meanwhile, the cosmetic dispenser 1 may further include a second sensor 106 that detects the weight of the cosmetic discharged from the cartridge 5, and the second sensor 106 is a container 8 that receives the discharged cosmetic. It can be installed below the receiving body (7) where it is placed. That is, the first sensor 105 obtains the discharge amount through the load size detected by the cartridge 5 when discharging the cosmetic, and the second sensor 106 obtains the discharge amount through the load size detected by the receiving body 7 when discharging the cosmetic. Discharge volume can be obtained. The second sensor may be a weight sensor. When measuring the discharge amount only by the weight measured in the receiving body 7 and calculating the remaining amount of the cartridge, the measurement result was inaccurate because it was not possible to measure the cosmetics that volatilized or fell outside the receiving container. However, according to the present invention, the discharged weight and load force were calculated. By considering them together, measurement accuracy improves. In other words, the force when pressing a gas-filled container varies depending on the gas load, so by attaching a load cell to the pusher and measuring the load force when pressing the container, the amount discharged from the container, the amount remaining in the container, and when discharge begins are determined. It can be detected accurately.

The above description is merely an illustrative explanation of the technical idea of the present invention, and various modifications and variations will be possible to those skilled in the art without departing from the essential characteristics of the present invention.

Accordingly, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention, but rather to explain it, and the scope of the technical idea of the present invention is not limited by these embodiments.
