Description

Technical Field

[0001] The utility model relates to the technical field of skin care medical tools, in particular to an electric quantitative medicine applicator. Background Art

[0002] Existing hair care liquid, hair mask, hair growth liquid, essential oil, etc. are generally squeezed into the palm of the hand and rubbed before applying. The hair is repeatedly rubbed with both hands to evenly apply the hair care liquid to the scalp, and then combed with a comb. This operation process is relatively cumbersome, and most hair care liquids adhere to the hair, which cannot achieve the ideal scalp care effect. Therefore, a scalp medicine applicator has appeared on the market. The scalp medicine applicator is provided with liquid discharge comb teeth. Liquid is loaded into the medicine chamber of the scalp medicine applicator, and the liquid in the medicine chamber is guided to the scalp by combing the hair. However, if the liquid is a paste or a viscous essential oil product, it is easy to block the liquid outlet of the liquid discharge comb teeth during use, resulting in poor liquid discharge or even no liquid discharge.

[0003] In order to solve the problem of blockage, technicians have developed a drug-dispensing device for squeezing out drugs. For example, Chinese patent document CN202223213937.6 discloses an automatic extrusion device, skin care equipment and medical equipment, in which a motor drives a worm to rotate and drives six reduction gears to rotate, thereby driving the rack to move, so as to drive the piston to move in the storage chamber. Through the transmission connection between the worm, six gears and the rack, the motor can drive the piston to move in the direction of the storage tube outlet, so as to realize automatic extrusion of liquid, colloid or paste-like cosmetics or medical supplies. However, the extrusion device does not have an extrusion limit setting, and the piston may be squeezed over the top of the comb teeth or the rack may not be moved in place due to extrusion, resulting in residual liquid in the storage tube. Moreover, the extrusion device has a complex structure and high precision requirements for each transmission component. The assembly between the worm, each gear and the rack is difficult. After repeated use, the transmission components are also prone to wear and jamming, and its driving scheme is unreliable.

[0004] Therefore the prior art still needs to be improved and enhanced. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide an electric quantitative medicine feeder to solve the problem that the prior art has no limit control.

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] It should be noted that when a component is referred to as being "mounted on", "fixed on" or "disposed on" another component, it may be directly on the other component or there may be an intermediate component at the same time. When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be an intermediate component at the same time.

[0027] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of the present invention are merely relative concepts or are based on the normal use status of the product and should not be considered as restrictive.

[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides an electric quantitative medicine applicator, which includes a motor 1, a control component 2, a medicine storage box 3, and a liquid discharge drive component 4 that can move and push medicine in the medicine storage box 3. The control component 2 is electrically connected to the motor 1 and is used to control the rotation state of the motor 1. One end of the liquid discharge drive component 4 is located in the medicine storage box 3, and the other end of the liquid discharge drive component 4 is connected to the motor 1, that is, linked with the motor. The control component 2 triggers the motor 1 to rotate, so that the liquid discharge drive component 4 moves in the medicine storage box 3 to push medicine.

[0029] When the liquid discharge drive assembly 4 reaches the medicine storage box 3 medicine discharge limit or the control assembly 2 receives a reset command, the control assembly 2 triggers the motor 1 to reset the liquid discharge drive assembly 4, which can prevent the liquid discharge drive assembly 4 from being pushed forward all the time, causing self-damage or damaging the medicine storage box 3. Among them, the medicine discharge limit is the maximum position at which the liquid discharge drive assembly 4 can be pushed outward from the medicine storage box 3. This maximum position can prevent the liquid discharge drive assembly 4 from damaging the medicine storage box 3 and other components, and can also completely push out the liquid in the medicine storage box 3 to avoid liquid waste. When in use, the motor 1 controls the liquid discharge drive assembly 4 to push out liquid, colloid or paste skin care products, care solutions, essential oils or medical supplies, etc., which can achieve the characteristics of automatic medicine discharge (or liquid discharge), uniform medicine discharge (or liquid discharge), and quantitative medicine discharge (or liquid discharge).

[0030] The medicine storage box 3 includes a medicine storage bin 31, a tooth plate sleeve 32 and a medicine discharging tooth plate 33, wherein the medicine discharging tooth plate 33 is placed in the tooth plate sleeve 32, and the medicine discharging teeth 331 on the medicine discharging tooth plate 33 extend out of the tooth plate sleeve 32, the tooth plate sleeve 32 is connected to the medicine storage bin 31, and the top end of the medicine storage bin 31 presses the medicine discharging tooth plate 33, so that the medicine in the medicine storage bin 31 will not seep out from the gap between the medicine discharging tooth plate 33 and the tooth plate sleeve 32.

[0031] In this embodiment, the medicine discharging tooth plate 33 has multiple specifications, which can be selected according to the different properties of the medicine. For example, when the medicine is in a paste state, a medicine discharging tooth plate 33 with a larger through hole of the medicine discharging tooth can be selected. When the medicine is in a flowing state, a medicine discharging tooth plate 33 with a smaller through hole of the medicine discharging tooth can be selected, or a tooth plate with a ball liquid discharging can be used. Users can combine them as needed when using, which also makes the applicability of the utility model higher. Specifically, when the liquid discharging drive component 4 is pushed toward the front end of the medicine storage box 3, the skin care products, care solutions or medical supplies in the liquid, colloid or paste form in the medicine storage box 3 are squeezed out (also understood as pushed out) from the medicine discharging tooth 5 for easy application.

[0032] When filling medicines, the electric quantitative medicine feeder is placed upright, the tooth plate sleeve 32 is removed, the medicines are loaded into the medicine storage bin 31, and then the tooth plate sleeve 32 is tightened. During the tightening process, the excess air in the medicine storage bin 31 can be discharged through the medicine outlet hole of the medicine outlet tooth plate 33, so that the air pressure in the medicine storage bin 31 is connected to the atmosphere. Compared with the existing method, it is necessary to invert the electric quantitative medicine feeder, remove the medicine storage box, load the medicine, and then tighten it with the tooth plate sleeve 32. However, during the tightening process, since the liquid outlet drive component 4 needs to be placed in the medicine storage bin, its volume becomes smaller, the air pressure in the medicine storage bin will increase, which will cause the medicine outlet tooth plate to drip, resulting in waste. The utility model can solve this defect.

[0033] Preferably, the medicine storage bin 31 is transparent, an observation window (not shown in the figure) may be provided on the tooth plate sleeve 32, and a scale (not shown in the figure) may be provided at the observation window, so that the user can visually observe the remaining medicine in the medicine storage bin 31.

[0034] Furthermore, a light assembly 34 is also provided at the medicine storage bin 31, and the light assembly 34 is electrically connected to the control assembly 2, and has a lighting effect when in use, which makes people happy, and can also facilitate observation of the remaining medicine in a dark environment.

[0035] Please also read Figure 5 , the liquid discharge drive assembly 4 includes a screw rod 41 and a pusher 42, one end of the screw rod 41 is connected to the output shaft of the motor 1, and the pusher 42 is sleeved on the screw rod 41 and rotates with the rotation of the screw rod 41. The liquid discharge drive assembly 4 also includes two limiting ribs 43 for making the pusher 42 move linearly, and the pusher 42 has a limiting portion 421 placed between the two limiting ribs 43. When the motor 1 rotates, the screw rod 41 connected thereto rotates synchronously, and under the action of the two limiting ribs 43 and the limiting portion 421, the pusher 42 sleeved on the screw rod 41 can only rise or fall along the screw rod 41. Here, the cooperation of the two limiting ribs 43 and the limiting portion 421 is used to convert the rotational motion of the pusher 42 into linear motion, so that the pusher 42 can only rise and fall along the screw rod 41, thereby ensuring the reliability of pushing the medicine.

[0036] Among them, a piston rod 422 is provided on one side of the pusher 42, and a piston component 44 is provided at the end of the piston rod 422. The piston component 44 is located in the medicine storage box 3. When the pusher 42 is raised or lowered, the piston component 44 is synchronously advanced or retracted along the medicine storage box 3 to push out liquids, pastes or colloids such as skin care products, care solutions or medical supplies, or skin care products, care solutions or medical supplies that are inhaled into liquids, colloids or pastes (when it is necessary to inhale skin care products, essential oils, care solutions or medical supplies that are in liquids, colloids or pastes, insert the medicine tooth 5 into the skin care products, essential oils, care solutions or medical supplies that are in liquids, colloids or pastes, and control the motor 1 to reset to inhale the skin care products, care solutions or medical supplies that are in liquids, colloids, essential oils or pastes). Since the output speed of the motor 1 is controllable, the speed of the piston component 44 in the medicine storage box 3 is also controllable, that is, the quantitative and uniform extrusion of liquids, pastes or colloids such as skin care products, care solutions or medical supplies can also be achieved through the utility model. Of course, the medicine storage box 3 may be provided with an openable cover, and after the pusher 42 is reset, the cover may be opened to add liquid, paste or colloid, and the present invention does not impose any limitation on this.

[0037] In this embodiment, the pusher 42 and the piston rod 422 are integrally formed, which can reduce the assembly process and make the connection strength between the pusher 42 and the piston rod 422 stronger, the service life longer, and better adapt to the release of the paste.

[0038] Please continue reading Figure 2 , Figure 3 and Figure 4The piston component 44 includes a fixing part 441, a snap-fit ​​part 442 and a soft rubber part 443. The fixing part 441 is connected to the end of the piston rod 422, and the soft rubber part 443 is covered on the outside of the snap-fit ​​part 442. The snap-fit ​​part 442 is buckled with the fixing part 441. During assembly, the fixing part 441 can be fixed to the end of the piston rod 422 by screws, and then the snap-fit ​​part 442 is installed in the soft rubber part 443. Finally, the snap-fit ​​part 442 is buckled on the fixing part 441 so that the two are tightly buckled to complete the assembly. The assembly method is simple and can make full use of the spatial structure of the electric quantitative medicine applicator, making the structure of the electric quantitative medicine applicator more compact, thereby reducing the volume of the electric quantitative medicine applicator.

[0039] Specifically, the buckle 442 has a hook 4421 that is engaged with the fixing member 441, so that the two are connected and fastened, and the assembly is simple. Further, the outer edge of the soft rubber member 443 has at least one flange 4431, and the outer diameter of the flange 4431 is greater than or equal to the inner diameter of the medicine storage box 3, so that the soft rubber member 443 and the inner diameter of the medicine storage box 3 are interference fit, so that the soft rubber member 443 and the inner diameter of the medicine storage box 3 are in a sealed state, so that the piston member 44 can push out or suck in the skin care products, care solutions or medical supplies during the advancement or retraction process, and also when the piston member 44 pushes out the liquid, colloid or paste skin care products, care solutions or medical supplies, there will be no residue in the inner diameter of the medicine storage box 3, which will lead to waste of skin care products, care solutions or medical supplies.

[0040] Since the soft rubber part 443 is made of soft rubber or silicone, the soft rubber part 443 can slide along the inner wall of the medicine storage box 3 while ensuring the sealing effect. In this embodiment, the flanges 4431 are two, which can play a good sealing role without increasing the resistance of the piston rod 422 due to excessive effort, so that the flanges 4431 and the inner diameter of the medicine storage box 3 are in the best state.

[0041] The control component 2 includes a main board 21, a control key 22, a first travel switch 23 and a second travel switch 24. The control key 22 and the motor 1 are electrically connected to the main board 21. The first travel switch 23 and the second travel switch 24 are fixed on the main board 1 to reduce the assembly process and make the connection between the first travel switch 23 and the second travel switch 24 and the main board 21 more stable.

[0042] Specifically, the pusher 42 is located between the first travel switch 23 and the second travel switch 24. The first travel switch 23 and the second travel switch 24 can be set at the initial position and the liquid outlet limit of the pusher 42, respectively used for the moving travel of the pusher 42. The control key 22 includes but is not limited to a mechanical key, a touch key, a key displayed on a touch screen, etc. Specifically, the light assembly 24 is fixed on the main board 1 to reduce the assembly process, so that the light assembly 24 emits light in the direction of the medicine outlet tooth plate 33.

[0043] The push member 42 is provided with a first contact portion 45 for contacting the first travel switch 23 and a second contact portion 46 for contacting the second travel switch 24. The first contact portion 45 and the second contact portion 46 can be convex or flat, and only need to be able to conduct the first travel switch 23 and the second travel switch 24 during the movement. There is no restriction on the shapes of the two contact portions.

[0044] When the motor 1 is not started, the pusher 42 is located at the bottom of the medicine storage box 3. At this time, the first contact 45 touches the first stroke switch 23, and the first stroke switch 23 is in the closed state. At this time, the pusher 42 cannot move toward the motor side. When the motor 1 is started, it drives the screw rod 41 to rotate, so that the pusher 42 rises, and the first contact 45 leaves the first stroke switch 23. At this time, the first stroke switch 23 is in the open state. When the piston component 44 rises to the medicine discharging limit position (i.e., the front end of the medicine storage box 3), the second contact 46 touches the second stroke switch 24, so that the second stroke switch 24 is closed and feedbacks the signal to the main board. At this time, the main board controls the motor 1 to reverse and drive the piston component 44 to move downward (i.e., move toward the motor side). When the first contact 45 touches the first stroke switch 23 (i.e., returns to the initial position), the first stroke switch 23 is closed and feedbacks the retreat limit signal to the main board, so that the motor stops rotating, thereby preventing the pusher 42 from retreating too far.

[0045] Of course, during use, the motor 1 can also be reset by controlling the control key 22, such as: when the control key 22 is triggered for the first time (such as a short press), the motor 1 starts to make the pusher 42 rise, and when the control key 22 is triggered for the second time, the motor 1 pauses, and when the control key 22 is triggered twice in succession, the motor 1 resets (i.e. returns to the original position). The two reset methods can control the motor 1 to reset, and the specific method can be selected according to usage requirements or user habits.

[0046] The utility model adopts the driving structure and limit control method of the screw rod 41, the pushing member 42, the first stroke switch 23, and the second stroke switch 24, which simplifies the structure of the electric quantitative medicine applicator, reduces the accuracy requirements of the driving components, reduces the cost of the electric quantitative medicine applicator, and the push-out and reset positions can be accurately controlled, thereby improving the reliability of the electric quantitative medicine applicator.

[0047] like Figures 2 to 4As shown, the electric quantitative medicine applicator also includes a mounting bracket 6 and a rotating shaft 7. The rotating shaft 7 is fixed on the mounting bracket 6. The other end of the screw rod 41 is sleeved on the rotating shaft 7. Through the cooperation between the screw rod 41 and the rotating shaft 7, the screw rod 41 will not get stuck when rotating. In this embodiment, the rotating shaft 7 and the mounting bracket 6 are separated, which can increase the wear resistance of the rotating shaft 7. The rotating shaft 7 is made of POM material. Since the mounting bracket 6 is partially exposed and belongs to the appearance part, it can be made of ABS material and can be electroplated, but it is not wear-resistant. The separate arrangements in this embodiment can greatly increase the service life of the product.

[0048] The electric quantitative medicine applicator also includes a body 8, and the mounting bracket 6 is connected to the body 8, and a first sealing ring 81 is provided at the connection to seal the connection between the body 8 and the mounting bracket 6, so as to prevent water or dirt from entering the body 8 and causing bacterial growth or affecting the service life of the motor 1; the mounting bracket 6 has a through hole for the piston rod 422 to pass through, and a second sealing ring 82 is sleeved on the piston rod 422, and the second sealing ring 82 is located at the through hole (not numbered in the figure). The second sealing ring 82 can prevent liquid, colloid or paste skin care products, care solutions, essential oils or medical supplies in the medicine storage box 3 from entering the body 8, and it is also convenient for cleaning the piston component 44.

[0049] Furthermore, a third sealing ring 35 is provided at the connection between the medicine storage bin 31 and the mounting bracket 6, so that the medicine storage bin 31 and the mounting bracket 6 are sealed, thereby preventing water or dirt from entering the fuselage 8 during use or cleaning.

[0050] Specifically, the body 8 also has a bottom cover 83, and a fourth sealing ring 84 is provided at the connection between the bottom cover 83 and the body 8 to prevent water or dirt from entering the body 8 during use or cleaning.

[0051] Among them, the electric quantitative medicine applicator also includes a decorative piece 85 and a protective cover 86. The decorative piece 85 is connected to the mounting bracket 6, and when assembled with the mounting bracket 6, it presses the second sealing ring 82 so that the second sealing ring 82 will not be displaced when the piston rod 422 is extended or retracted. Specifically, the medicine storage box 3 is detachably connected to the decorative piece 85, which is convenient for removing and cleaning the medicine storage box 3, and is also convenient for containing liquid, colloid or paste skin care products, care solutions, essential oils or medical supplies, etc. The two filling methods are more conducive to user use. The protective cover 86 is arranged on the medicine dispensing tooth 5 to prevent dust and protect the medicine dispensing tooth 5, so as to prevent bacteria or dirt from entering the medicine storage box 3 from the medicine dispensing tooth 5 when not in use, causing the liquid, colloid or paste in the medicine storage box 3 to deteriorate.

[0052] Preferably, the electric quantitative medicine applicator also includes a power supply component 9 and an indicator light component 10. The indicator light component 10 is electrically connected to the power supply component 9 and the control component 2. The power supply component 9 includes a battery 91, a battery holder 92 and a charging component 93. The battery holder 92 is installed in the fuselage 8. The battery 91 is placed in the battery holder 92. The motor 1 and the control component 2 are not electrically connected to the battery 91. The charging component 93 is electrically connected to the battery 91. This power supply and charging structure is a prior art and will not be described here. The electric quantitative medicine applicator is powered by the power supply component 9, and can be charged and reused multiple times. The operation is simple. The current working status of the electric quantitative medicine applicator can be visually observed through the indicator light component 10, which is more convenient to use.

[0053] In summary, the electric quantitative medicine dispenser provided by the utility model, when the control component triggers the motor to rotate, causes the liquid discharge drive component to move in the medicine storage box to push the medicine, when the liquid discharge drive component reaches the medicine storage box medicine discharge limit or the control component receives a reset command, the control component triggers the motor to reset the liquid discharge drive component, which can prevent the liquid discharge drive component from being pushed forward all the time, causing self-damage or damage to the medicine storage box. When in use, the liquid discharge drive component is controlled by the motor to push out liquid, colloid or paste skin care products, care solutions or medical supplies, etc., which can achieve the characteristics of automatic medicine discharge, uniform medicine discharge, and quantitative medicine discharge.

[0054] In addition, the utility model has a relatively simple structure, and has low requirements for the accuracy of the components themselves and the assembly accuracy, which reduces the cost of the electric quantitative applicator. It is also easy to operate and use, and is suitable for applying various liquid, colloid or paste-like skin care products or medicines, and has a wide range of applicability.

[0055] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the claims attached to the utility model.
