Description

Technical Field

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

[0002] Existing scalp medicine applicators are generally liquid medicine applicators. By loading liquid (such as hair growth liquid, hair care liquid, essential oil, etc.) into the medicine bin of the scalp medicine applicator and using the way of combing, the liquid medicine in the medicine bin is guided to the scalp. However, if the liquid medicine is a paste or a viscous essential oil product, it is easy to block the liquid outlet holes of the liquid outlet comb teeth during use, resulting in unsmooth liquid outlet or even no liquid outlet.

[0003] To solve the blockage problem, technicians have developed a medicine applicator device that extrudes medicine. For example, in the Chinese patent document CN202223213937.6, an automatic extrusion device, a skin care device and a medical device are disclosed. A motor drives a worm to rotate to drive six reduction gears to rotate, thereby driving a rack to move, so as to drive a piston to move in a storage cavity. Through the transmission connection between the worm, the six gears and the rack, the motor can drive the piston to move towards the liquid outlet of the storage tube, realizing the automatic extrusion of liquid, colloid or paste-like cosmetics or medical supplies. However, this extrusion device has a complex structure, high precision requirements for each transmission component, great assembly difficulty between the worm, each gear and the rack, and the transmission components are prone to wear and jamming after multiple uses, and its driving scheme is unreliable.

[0004] Therefore, the existing technology still needs to be improved. Summary of the Utility Model

[0005] In view of the deficiencies of the above-mentioned existing technology, the purpose of the utility model is to provide an electric medicine applicator to solve the problems of complex structure and great assembly difficulty in the existing technology.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] An electric medicine applicator includes a medicine bin, a liquid pushing mechanism and a driving mechanism for driving the liquid pushing mechanism to move in the medicine bin. The liquid pushing mechanism includes a liquid pushing rod, a liquid pushing part arranged in the medicine bin and a rotation stopping part for making the liquid pushing rod move linearly. The driving mechanism includes a motor and a lead screw. One end of the lead screw is provided with a passive gear, which meshes with the active gear on the motor. One end of the liquid pushing rod is inserted into the lead screw and is rotatably connected with the lead screw. The other end of the liquid pushing rod is connected with the liquid pushing part.

[0008] In the electric medicine applicator, a lifting groove for controlling the moving stroke of the liquid pushing rod is arranged on the liquid pushing rod, and the rotation stopping part is arranged in the lifting groove.

[0009] In the described electric medicine applicator, the liquid pushing member is a soft liquid pushing member, and at least two flanges that are tightly fitted with the inner wall of the medicine bin are provided on the side wall of the liquid pushing member.

[0010] In the described electric medicine applicator, the lifting groove is a through groove penetrating the push rod, and the rotation stopping member passes through the lifting groove.

[0011] In the described electric medicine applicator, a limiting notch is provided in the middle of the rotation stopping member, and a rib is provided in the lifting groove and is matched with the limiting notch.

[0012] The described electric medicine applicator further includes a limiting frame. A threaded hole and an installation groove for accommodating the rotation stopping member are provided on the limiting frame, and the rotation stopping member is fixed to the limiting frame by a screw.

[0013] In the described electric medicine applicator, the edge of the end face of the liquid pushing member is higher than the middle of the end face.

[0014] The described electric medicine applicator further includes a main board, a lamp board and a key board. One end of the key board has a plug connector, the lamp board is provided with a plug interface, the plug interface is plugged with the plug connector, and the other end of the key board is electrically connected to the main board.

[0015] In the described electric medicine applicator, a wire routing groove hole is provided on the key board.

[0016] In the described electric medicine applicator, multiple groups of LED lights are provided on the lamp board. The plug connector has pins with the same number as the number of groups of LED lights, and the plug interface has jacks corresponding to the pins.

[0017] In the described electric medicine applicator, one end of the medicine bin is open, a detachable tooth kit is provided outside the medicine bin, the tooth kit is a light-transmitting tooth kit, and a plurality of liquid outlet teeth are provided on the tooth kit; a protective cover is further covered on the tooth kit, and a fastening member is provided in the protective cover.

[0018] Compared with the prior art, the electric medicine applicator provided by the present utility model controls the lifting of the push rod by a motor driving a lead screw to push the medicine. When the motor is started, the lead screw rotates synchronously, causing the push rod connected thereto to move upward, so that the liquid pushing member moves in the medicine bin to push out the medicine. When the liquid pushing member reaches the top of the medicine bin, the motor is blocked and stops rotating to completely extrude the medicine. When the motor rotates reversely, the push rod is driven to retreat and reset for adding medicine. The present utility model adopts the method of directly driving the lead screw by a motor gear to control the liquid pushing, which has high reliability, and requires fewer devices for liquid pushing drive, facilitating assembly. Moreover, when in use, by controlling the liquid pushing mechanism by the motor to push out liquids, colloids or paste-like skin care products, nursing solutions, essential oils or medical supplies, etc., it can also achieve the characteristics of automatic medicine delivery, uniform medicine delivery and quantitative medicine delivery.

[0027] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] It should be noted that when a component is referred to as being "mounted on", "fixed to" or "disposed on" another component, it can 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 can be directly connected to the other component or there may be an intermediate component at the same time.

[0029] It should also be noted that the orientation terms such as left, right, up, and down in the embodiments of the present utility model are only relative concepts to each other or are referenced based on the normal use state of the product, and should not be considered restrictive.

[0030] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a kind of electric medicine applicator provided by the present utility model includes a medicine bin 1, a liquid pushing mechanism 2, and a driving mechanism 3 for driving the liquid pushing mechanism 2 to move in the medicine bin 1. The liquid pushing mechanism 2 includes a liquid pushing rod 21, a liquid pushing member 22 arranged in the medicine bin 1, and a rotation preventing member 23 for making the liquid pushing rod 21 move linearly. The driving mechanism 3 includes a motor 31 and a lead screw 32. One end of the lead screw 32 is provided with a passive gear 321, which meshes with the active gear 311 on the motor 31. One end of the liquid pushing rod 21 is inserted into the lead screw 32 and is rotatably connected to the lead screw 32. The other end of the liquid pushing rod 21 is connected to the liquid pushing member 22.

[0031] In this embodiment, the motor is a stepping motor, which has high control precision, small torque, and automatically stops when encountering resistance. The active gear 311 is located at the center of the motor, and the driving force of the motor is output from the center of the motor, rather than an eccentric driving method. And the way that the active gear on the motor directly drives the passive gear on the lead screw makes the liquid pushing operation more stable.

[0032] When the motor 31 is started, it drives the lead screw 32 to rotate synchronously, causing the liquid pushing rod 21 connected thereto to move upward, so that the liquid pushing member 22 moves in the medicine bin 1 to push out the medicine (which can be liquid, colloid or paste-like skin care products, nursing solutions, essential oils or medical supplies, hereinafter referred to as medicine). When the liquid pushing member 22 reaches the top of the medicine bin 1 (i.e., the mouth of the medicine bin 1), the motor 31 is blocked and stops rotating, so that all the medicine is squeezed out. When the motor rotates in reverse, it drives the liquid pushing rod to return to its original position, making the medicine bin empty for adding medicine. The present utility model uses the method of directly driving the lead screw by the motor gear, which has high reliability in liquid pushing control, and requires fewer devices for liquid pushing drive, facilitating assembly. Moreover, when in use, by controlling the liquid pushing mechanism with the motor to push out liquid, colloid or paste-like skin care products, nursing solutions, essential oils or medical supplies, etc., it can also achieve the characteristics of automatic medicine output, uniform medicine output, and quantitative medicine output.

[0033] In this embodiment, a lifting groove 211 for controlling the moving stroke of the liquid pushing rod 21 is arranged on the liquid pushing rod 21, and the rotation preventing member 23 is arranged in the lifting groove 211 (as shown in Figure 3 , Figure 4 and Figure 5 ), and the rotational motion of the lead screw 32 is converted into a linear motion through the cooperation of the lifting groove 211 and the rotation preventing member 23, that is, when the lead screw 32 rotates, the liquid pushing rod 21 moves up and down.

[0034] Specifically, an internal thread 322 is provided inside the lead screw 32. One end of the liquid pushing rod 21 has an external thread 212, and the external thread 212 is screwed with the internal thread 322. That is, the end of the liquid pushing rod 21 with the external thread 212 is inserted into the lead screw 32 and screwed with the internal thread 322 of the lead screw 32. When the motor 31 drives the lead screw 32 to rotate, the liquid pushing rod 21 can rotate synchronously. Since the rotation stopping member 23 is placed in the lifting groove 211, the rotation of the liquid pushing rod 21 is restricted, and it can only move linearly along the lifting groove 211, thereby achieving the liquid pushing effect.

[0035] Among them, the lifting groove 211 is a through groove penetrating the liquid pushing rod 21. The rotation stopping member 23 is a circular, trapezoidal or square pin, which passes through the lifting groove 211, so that the liquid pushing rod 21 is evenly stressed, without skew or jamming, and the service life of the liquid pushing rod 21 can be extended. The rotation stopping member 23 is made of stainless steel material, making it not easy to wear or rust, and having a small friction coefficient, which is beneficial to ensuring the service life of the liquid pushing rod 21. And this application adopts the method of central rotation drive, and the way that the linearly moving liquid pushing rod 21 is located inside the lead screw 32 makes the movement stable during liquid pushing, with a long service life and low noise.

[0036] Please continue to refer to Figures 1 to 5 , the electric medicine applicator further includes a limit frame 4. A threaded hole (not labeled in the figure) is provided on the limit frame 4, and the rotation stopping member 23 is fixed to the limit frame 4 by a screw (not labeled in the figure). The screw can be a flat head screw, which can pass through the threaded hole and be fixed to the limit frame 4. While fixing, the head of the screw presses the rotation stopping member 23, so that when the lead screw 32 moves, the rotation stopping member 23 cannot rotate to ensure the linear movement of the liquid pushing rod 21. Of course, in other embodiments, holes can also be provided on the rotation stopping member 23, and the screw passes through the holes on the rotation stopping member 23 and is fixed to the limit frame 4, which can also achieve the effect of fixing the rotation stopping member 23, and this is not limited here.

[0037] Among them, the position of the rotation stopping member 23 and the length of the lifting groove 211 can control the liquid pushing stroke of the liquid pushing rod 21. That is, when the liquid pushing member 22 abuts against the top (i.e., the liquid outlet) of the medicine bin 1, the bottom of the lifting groove 211 abuts against the rotation stopping member 23, so that the liquid pushing member 22 can completely push out the medicine in the medicine bin 1, avoiding waste of medicine and not damaging components such as the medicine bin 1.

[0038] Furthermore, an installation groove 41 for accommodating the rotation stopping member 23 is provided on the limit frame 4, so that a part of the rotation stopping member 23 is located in the installation groove 41, so that the screw can better press the rotation stopping member 23 and is more stable when the liquid pushing rod 22 moves up and down.

[0039] In an optional embodiment, the middle part of the stopper 23 has a limiting notch 231, and the lifting groove 211 is provided with a convex rib 213 that matches the limiting notch, that is, the diameters of the two ends of the stopper 23 are larger than the middle diameter of the stopper 23, and the length of the limiting notch is equal to the convex rib 213 on the liquid pushing rod 22, so that the convex rib 213 is just engaged with the limiting notch, and does not limit the lifting and lowering of the liquid pushing rod 22. In this embodiment, a limiting notch 231 is provided on the stopper 23, and a convex rib 213 is provided on the lifting groove 211, so that the liquid pushing rod 22 can only move in a straight line when lifting and lowering, and will not shake or tilt during the lifting process, further ensuring the stability of the liquid pushing operation and the service life of the liquid pushing mechanism 2.

[0040] Optionally, the electric quantitative medicine applicator also includes a body 5, the limit frame 4 is fixed to the body 5 by screws, the medicine bin 1 is also fixed to the limit frame 4 by screws, and a first sealing ring 51 is provided at the connection between the medicine bin 1 and the body 5 to ensure the waterproof performance of the electric medicine applicator and prevent water or dirt from entering the body 5 to cause bacterial growth or affect the service life of the motor 31.

[0041] See also Figures 2 to 5 The liquid pushing mechanism 2 also includes a first sleeve 33 and a second sleeve 34. The body 5 of the electric medicine applicator has a positioning column 52 for installing the first sleeve 33. The first sleeve 33 is sleeved on the positioning column 52 and fixed by screws. The limiting frame 4 is provided with a recess for installing the second sleeve 34. One end of the screw rod 32 is sleeved on the first sleeve 33, and the second sleeve 34 is sleeved on the other end of the screw rod 32. The first sleeve 33 and the second sleeve 34 make the screw rod 32 rotate more smoothly without jamming, and will not wear the body 5 and the limiting frame 4, and will not produce abnormal noise, so as to improve the user experience and extend the service life of the electric medicine applicator.

[0042] In this embodiment, the liquid pushing member 22 is a soft liquid pushing member, such as a deformable material such as a silicone member, a rubber member, etc. The side wall of the liquid pushing member 22 has at least two flanges 221 that are tightly matched with the inner wall of the medicine warehouse 1, wherein one flange 221 is arranged on the end face of the liquid pushing member 22, and the other flange 221 is arranged on the bottom surface of the liquid pushing member 22. The flanges 221 at both ends of the liquid pushing member 22 can make the force between the liquid pushing member 22 and the inner wall of the medicine warehouse 1 uniform when the liquid pushing member 22 pushes, and prevent the liquid pushing rod 21 from deflecting to one side, causing the flange 221 of the end face to be inconsistently sealed, or even to have a gap. Moreover, the two flanges 221 are in contact with the inner wall of the medicine warehouse 1, so that a closed space is formed between the two flanges 221, and when the pressure in the medicine warehouse 1 is insufficient, it also plays a certain sealing role, so that the medicine can be smoothly pushed out.

[0043] Please also read Figure 6, the electric medicine applicator further includes a main board 6, a lamp board 7 and a key board 8. One end of the key board 8 has a plug connector 81, and the lamp board 7 is provided with a socket 71. The socket 71 is plugged with the plug connector 81, enabling the key board 8 and the lamp board 7 to be quickly installed and disassembled. Compared with the existing connection methods such as welding or twisting wires together, the operation is more convenient and the connection is reliable. The other end of the key board 8 is electrically connected to the main board 6, and the key board 8 controls the opening and closing of the electric medicine applicator.

[0044] Specifically, a wire groove hole 82 is formed on the key board 8. Through the wire groove hole 82, wire entanglement can be avoided, facilitating installation. Optionally, two keys are provided on the key board 8, one for controlling power on / off and the other for realizing functions such as pushing liquid and resetting by controlling the forward and reverse rotation of the motor.

[0045] Among them, multiple groups of LED lights 72 are provided on the lamp board 7. Each group of lights can be a single color, such as red, blue, yellow, etc. The plug connector 81 has pins 811 with the same number as the number of groups of LED lights 72, and the socket 71 has corresponding holes 711 for the pins 811. By inserting the pins 811 into the holes 711, the multiple groups of LED lights 72 are electrically connected. The installation is extremely simple, and the main board can control the lighting and extinguishing of each group of lights.

[0046] Further, one end of the medicine storage 1 is open, and a detachable tooth kit 9 is provided outside the medicine storage 1. A number of liquid outlet teeth 92 are provided on the tooth kit 9, enabling the liquid outlet teeth 92 to be connected to the medicine storage 1. When the liquid pushing member 22 pushes the liquid, the medicine flows out from the liquid outlet teeth 92.

[0047] Specifically, the tooth kit 9 includes a tooth plate sleeve 91, liquid outlet teeth 92 and auxiliary teeth 93. The liquid outlet teeth 92 are evenly distributed on the tooth plate sleeve 91. The tooth plate sleeve 91 is detachably connected to the medicine storage 1. A second sealing ring 94 is provided at the bottom of the tooth plate sleeve 91. When the tooth plate sleeve 91 is connected to the medicine storage 1, the end face of the medicine storage 1 presses the tooth plate sleeve 91, which can prevent liquid leakage.

[0048] Specifically, the tooth kit 9 is screwed to the medicine storage 1. When the tooth kit 9 is removed, liquid medicine can be added to the medicine storage 1. When the liquid pushing mechanism 2 advances towards the front end (i.e., the top end) of the medicine storage 1, the liquid, colloid or paste-like skin care products, nursing solutions or medical supplies in the medicine storage 1 are extruded (or can be understood as pushed out) from the liquid outlet teeth 92 for easy application.

[0049] The liquid outlet teeth 92 have multiple specifications and can be selected according to the different properties of the medicine. For example, when the medicine is in a paste state, the liquid outlet teeth 92 with larger through holes can be selected. When the medicine is in a flowing state, the liquid outlet teeth 92 with smaller through holes can be selected, or the liquid outlet teeth 92 with ball liquid discharge can be selected. Users can combine them according to their needs during use, which also makes the applicability of the utility model higher.

[0050] Further, the edge of the end face of the liquid pushing member 22 is higher than the middle part of the end face, that is, the end face of the liquid pushing member 22 is bowl-shaped, so that during the pushing process of the liquid pushing member 22, due to the reduction of the space in the medicine bin 1 and the increase of the pressure, the end face of the liquid pushing member 22 is slightly opened, so that the flange 221 is more closely attached to the inner wall of the medicine bin 1, and the medicine is prevented from flowing back from the periphery of the liquid pushing member 22, so that the liquid pushing member 22 can scrape the medicine on the inner wall of the medicine bin 1 during the pushing process. In addition, because the edge of the surface is higher than the middle part of the end face, the liquid pushing member 22 is deformed when it reaches the bottom of the medicine bin 1, so that the middle part of the end face of the liquid pushing member 22 abuts against the top of the tooth plate sleeve 91, so that the medicine in the medicine bin 1 can be squeezed clean, avoiding waste or the phenomenon that the amount of medicine does not meet the standard and the treatment effect does not meet the standard.

[0051] When filling medicine, the electric quantitative medicine feeder is upright, the tooth plate sleeve 91 is removed, the medicine is loaded into the medicine chamber 1, and the tooth plate sleeve 91 is tightened. During the tightening process, the excess air in the medicine chamber 1 can be discharged through the liquid outlet teeth 92, so that the air pressure in the medicine chamber 1 is connected to the atmosphere.

[0052] Preferably, the medicine bin 1 is transparent, an observation window (not shown in the figure) may be provided on the tooth plate sleeve 91, and the medicine bin 1 is provided with a scale 11 (not shown in the figure), so that the user can visually observe the remaining medicine in the medicine bin 1 through the observation window.

[0053] The tooth set 9 is a light-transmitting tooth set, so that the light emitted by the LED lamp 72 can be emitted through the tooth set 9, which has a lighting effect when used, making people happy, and can also facilitate observation of the remaining medicine in a dark environment. For example, when the red LED lamp is turned on, it can promote scalp blood circulation, and when the blue LED lamp 72 is turned on, it can relieve skin inflammation, etc., so that the electric medicine applicator has multiple light therapy functions to meet the needs of users.

[0054] Furthermore, the electric medicine applicator further comprises a protective cover 10 and a vibration motor 53. The protective cover 10 is arranged outside the tooth set 9, so that the medicine chamber 1 and the tooth set 9 can be shielded from light, and the liquid outlet teeth 92 and the auxiliary teeth 93 can be protected, and the dustproof effect can be achieved. The vibration motor 53 is installed in the body 5, so that the electric medicine applicator also has a vibration massage function, and the functions are diversified.

[0055] Furthermore, a tightening member 101 is provided in the protective cover 10. A through hole is formed in the middle of the tightening member 101 for the liquid discharging tooth 92 to be inserted. An annular tight-fitting groove (not labeled in the figure) is formed on the outer side of the through hole of the tightening member 101, that is, the width of the tight-fitting groove is smaller than the outer diameter of the auxiliary tooth 93. When the protective cover 10 and the tooth kit 9 are covered, the auxiliary tooth 93 is inserted into the tight-fitting groove, and the protective cover 10 is not easily detached.

[0056] During production, the vibration motor 53, the motor 31, the battery holder, etc. are directly arranged on the main board 6. During assembly, the driving gear 311 can be first mounted on the output shaft of the motor 31, then the battery, the main board 6, and the vibration motor 53 are loaded into the fuselage 5, then the key board 8 is connected to the main board 6, and the key is inserted into the key position on the fuselage 5. After that, the lead screw 32 is loaded into the fuselage 5, so that the driven gear 321 on the lead screw 32 meshes with the driving gear 311. The limit frame 4 is installed in the fuselage 5 and locked with screws. After that, the rotation stopping member 23 can be inserted into the lifting groove 211, then the liquid pushing rod 21 passes through the limit frame 4 and is inserted into the lead screw 32 and screwed to the bottom end of the lead screw. Then, the rotation stopping member 23 is fixed to the limit frame 4 by flat head screws. Then, the lamp board 7 is installed so that the plug connector 81 is inserted into the pin 811 on the mounting board. Then, the lamp board is fixed with screws. After that, the medicine bin and the tooth kit 9 can be installed. The assembly is particularly convenient, and the requirements for assembly accuracy are low, the assembly difficulty is low, and the number of assembly steps is small, etc.

[0057] In summary, the present utility model uses the method of directly driving the lead screw by the motor gear, so the reliability of the liquid pushing control is high, and the devices required for the liquid pushing drive are few, which is convenient for assembly. Moreover, during use, by controlling the liquid pushing mechanism by the motor to push out liquids, colloids or paste-like skin care products, nursing solutions, essential oils or medical supplies, etc., the characteristics of automatic medicine discharging, uniform medicine discharging, and quantitative medicine discharging can also be achieved.

[0058] In addition, the structure of the present utility model is simple and compact, which reduces the cost of the electric medicine applicator. Moreover, the installation of each component is simple, the assembly requirements are low, the operation is simple, and the use is convenient. It is suitable for applying various liquids, colloids or paste-like skin care products or medicines, and has a wide applicability.

[0059] It can be understood that for those of ordinary skill in the art, equivalent replacements or changes can be made according to the technical solution and the inventive concept of the present utility model, and all such changes or replacements should fall within the protection scope of the appended claims of the present utility model.
