Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic engineering, in particular to an eyeliner pen capable of evenly discharging liquid. Background Art

[0002] Eyeliner is a makeup tool used to outline the eye contour, emphasize the eye contour, change the eye shape, and make the eyes look more vivid and deep. Existing eyeliner pens still have some problems. For example, the patent with application number CN220384519U discloses an eyeliner pen that cannot control the uniform discharge of the eyeliner liquid, which easily leads to inconsistent lines and colors when used, affecting the makeup effect; in addition, the liquid-absorbing cotton column used in the eyeliner pen cannot ensure the stability of the liquid discharge when used, and the liquid is easy to splash when the eyeliner pen is swung. At the same time, large particles or tiny impurities in the eyeliner liquid will be directly adsorbed on the liquid-absorbing cotton column, and the liquid-absorbing cotton column will wear and age over time, making the liquid absorption effect worse, thereby causing performance degradation and affecting the uniformity of liquid discharge. Utility Model Content

[0003] 1. Technical issues to be resolved

[0004] In view of the limitations of existing liquid eyeliner pens, the utility model aims to provide a liquid eyeliner pen that can discharge liquid evenly, which can achieve uniform discharge of the liquid eyeliner pen, solve the problem of uneven discharge of the liquid eyeliner pen, and avoid liquid splashing when the liquid eyeliner pen is swung; at the same time, it can help to evenly mix the liquid and filter impurities to avoid clogging problems.

[0005] (II) Technical solution

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an eyeliner pen capable of evenly discharging liquid, comprising a pen body and a pen cap sleeved on the bottom end of the pen body; wherein a liquid storage tank is arranged inside the pen body, vibrators are symmetrically fixed on both sides of the outer surface of the liquid storage tank, a micro pump is fixed at the bottom of the liquid storage tank, a nozzle is fixedly connected to the other end of the micro pump, a pen tip is sleeved on the outer surface of the nozzle, the bottom end of the pen tip penetrates the inner wall of the bottom end of the pen body and extends to the outside of the pen body, the flow of the eyeliner liquid is controlled by controlling the state of the micro pump, and the eyeliner liquid is sprayed onto the pen tip through the nozzle, which helps to ensure that the eyeliner liquid on the pen tip is even and appropriate, and ensures that an even and appropriate amount of eyeliner liquid can be released when applying, thereby improving the uniformity and consistency of makeup; at the same time, it avoids the situation where liquid splashes due to shaking the eyeliner pen during use, thereby ensuring the safety and cleanliness of use.

[0007] Furthermore, the vibration of the vibrator is controlled by a motor, and the vibration of the vibrator drives the eyeliner liquid in the liquid storage tank to be fully mixed, preventing the components in the liquid from settling or stratifying, ensuring that the liquid maintains a consistent texture and color, thereby ensuring the uniformity and consistency of the applied color and lines; at the same time, the vibration of the vibrator can slow down the drying speed of the liquid, preventing the eyeliner liquid from drying up and affecting the uniformity of the liquid output.

[0008] Preferably, the micro pump includes a pump body, an infusion tube having one end connected to the pump body and the other end fixedly connected to the bottom of the liquid storage tank, and a discharge tube having one end connected to the pump body and the other end fixedly connected to the top of the nozzle. When the micro pump is working, the eyeliner liquid in the liquid storage tank enters the infusion tube, flows through the infusion tube and the pump body, and is discharged from the discharge tube, thereby providing a smooth channel for the flow of the eyeliner liquid, ensuring that the eyeliner liquid flows smoothly during the transportation process, effectively reducing the risk of liquid blockage in the infusion tube and the discharge tube, further ensuring the uniformity of the liquid output, and improving the reliability and stability of the product; in addition, the design of the micro pump stops the flow of liquid when the eyeliner pen is not in use, effectively preventing the eyeliner liquid from dripping or leaking, avoiding unnecessary loss of eyeliner liquid, keeping the environment clean, ensuring the safety of use, and extending the service life of the eyeliner pen.

[0009] It is further explained that when using a liquid eyeliner pen, sometimes the pen tip dries up or liquid is difficult to come out, and the eyeliner pen needs to be shaken vigorously to make the liquid come out, and shaking will cause the eyeliner liquid to splash. The use of a micro pump control can first ensure the smooth flow of the eyeliner liquid and avoid the phenomenon of drying up. At the same time, the micro pump can prevent the eyeliner liquid from flowing when not in use, and vigorously shaking will not cause liquid splashing, thereby ensuring the safety of use and the cleanliness of the environment.

[0010] Preferably, a first filter layer is provided at the connection between the infusion tube and the bottom of the liquid storage tank, and a second filter layer is provided at the connection between the discharge tube and the nozzle. The eyeliner liquid in the liquid storage tank will be filtered once when entering the infusion tube, and large particles and tiny impurities in the eyeliner liquid will be filtered out before entering the infusion tube, and the eyeliner liquid entering the nozzle through the discharge tube will be filtered again before entering the nozzle, and large particles and tiny impurities in the eyeliner liquid will be further filtered out. The eyeliner liquid filtered by the first and second filter layers has a purer and more uniform composition, so that the eyeliner liquid sprayed through the nozzle is more uniform, further ensuring the uniformity of the eyeliner liquid output; and the use of the filter layer helps to maintain the stability of the liquid, avoid changes in the quality of the liquid due to impurities or residual substances, and improve the product stability of the eyeliner pen; and the first filter layer helps to maintain the patency of the infusion tube, reduce the possibility of pipeline blockage, and ensure the uniform flow of the eyeliner liquid.

[0011] Preferably, the nozzle is an elongated nozzle with a number of spray holes evenly distributed at its outlet. After the eyeliner liquid enters the nozzle, it first passes through the elongated nozzle tube and then is sprayed out from the nozzle and evenly sprayed onto the pen tip. The pen tip can have a uniform and appropriate amount of eyeliner liquid, thereby ensuring the consistency of the applied lines and colors; the elongated nozzle can provide more delicate application and achieve a more delicate and accurate eyeliner effect. The elongated nozzle can provide more delicate application, making it easier for users to achieve a delicate and accurate eyeliner effect. The evenly distributed spray holes can ensure that the eyeliner liquid is evenly distributed when sprayed, avoiding the problem of uneven application caused by a single or uneven outlet, and improving the consistency of application.

[0012] Preferably, the bottom of the liquid storage tank is arranged as a "V"-shaped structure, the top surface of the liquid storage tank is provided with a button, and the top end is threadedly connected to the top end of the inner wall of the pen body, and the "V"-shaped structure of the bottom of the liquid storage tank can guide the eyeliner to flow evenly and fully to the first filter layer, making the liquid flow smoother, while ensuring sufficient filtration of the first filter layer, ensuring the uniformity of the eyeliner output, and improving the uniformity and consistency of application; the liquid storage tank and the pen body are detachably connected by threads, that is, the liquid storage tank can be removed, so as to facilitate its replacement.

[0013] Preferably, a motor is fixedly connected to the inner wall of the bottom of the pen body, and the motor is electrically connected to the micro pump, the vibrator and the button respectively. The motor can control the working status of the vibrator and the micro pump. The vibrator is controlled to help the liquid to be fully mixed and prevent the liquid from drying up, ensuring that the liquid maintains a consistent texture and color, thereby ensuring the uniformity and consistency of the applied color and lines; the micro pump is controlled to ensure the smooth flow and uniform discharge of the eyeliner liquid, ensuring the consistency and uniformity of the application, and preventing the liquid from splashing when swinging and avoiding dripping and leakage.

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Example 1: Please refer to Figures 1 to 4 The first specific embodiment of the utility model provides an eyeliner pen that can discharge liquid evenly, including a pen body 1 and a pen cap 2 sleeved on the bottom end of the pen body 1; wherein, a liquid storage tank 4 is arranged inside the pen body 1, and vibrators 7 are symmetrically fixed on both sides of the outer surface of the liquid storage tank 4, and a micro pump 6 is fixed at the bottom of the liquid storage tank 4, and the other end of the micro pump 6 is fixedly connected to a nozzle 9, and a pen tip 5 is sleeved on the outer surface of the nozzle 9, and the bottom end of the pen tip 5 penetrates the inner wall of the bottom end of the pen body 1 and extends to the outside of the pen body 1. Controlling the vibration of the vibrator 7 can fully mix the eyeliner in the liquid storage tank 4, which can effectively avoid the precipitation or stratification of the components in the liquid, and help the liquid to maintain a consistent texture and color, thereby ensuring the consistency of the applied lines and colors; controlling the state of the micro pump 6 to control the flow of the eyeliner liquid, thereby ensuring that the eyeliner liquid flows smoothly when needed, and stops flowing when not in use, effectively avoiding dripping or leakage of the eyeliner liquid, and avoiding liquid splashing when shaking or swinging the eyeliner pen.

[0025] The micro pump 6 includes a pump body 62, an infusion tube 61 connected to the pump body 62 at one end and fixedly connected to the bottom of the liquid storage tank 4 at the other end, and a discharge tube 63 connected to the pump body 62 at one end and fixedly connected to the top of the nozzle 9 at the other end. The coordinated cooperation of the infusion tube 61, the pump body 62 and the discharge tube 63 ensures that the eyeliner liquid is delivered unimpeded when the micro pump 6 is in working state, reduces the risk of blockage of the liquid in the infusion tube 61 and the discharge tube 63, helps to ensure the uniformity of the liquid discharge, and improves the stability and reliability of the product.

[0026] A first filter layer 41 is provided at the connection between the infusion tube 61 and the bottom of the liquid storage tank 4, and a second filter layer 91 is provided at the connection between the discharge tube 63 and the nozzle 9. During the flow of the eyeliner liquid, it is first filtered through the first filter layer 41, and the first filter layer 41 will initially filter out large particles and impurities in the eyeliner liquid. The eyeliner liquid after the initial filtration continues to flow, and then is filtered again through the second filter layer 91 to further filter out large particles and impurities in the eyeliner liquid. The eyeliner liquid obtained in this way can be purer and more uniform, ensuring the uniformity and stability of the eyeliner liquid composition, further ensuring the uniformity of the liquid output, and avoiding the impurities and particles in the liquid from affecting the quality and liquid output changes.

[0027] It should be further explained that the diameters of the filter plates of the first filter layer 41 and the second filter layer 91 mentioned above are different. Since the first filter layer 41 is for preliminary filtration and the second filter layer 91 is for further filtration, the filtration diameter of the second filter layer 91 should be smaller than the filtration diameter of the first filter layer 41 to further ensure that the eyeliner liquid obtains a more uniform and pure liquid after two filtrations.

[0028] The nozzle 9 is a slender nozzle with a plurality of spray holes 93 evenly distributed at its outlet. The eyeliner liquid enters the nozzle 9 through the micro pump 6 and is then sprayed out from the spray holes 93 on the surface of the nozzle 9. The nozzle 9 is provided with a pen tip 5. The eyeliner liquid is evenly sprayed onto the pen tip 5 through the spray holes 93, so that the eyeliner liquid on the pen tip 5 is even and appropriate, which can further ensure the uniformity of the eyeliner liquid discharge and ensure the uniformity and consistency of the lines and colors during application.

[0029] The bottom of the liquid reservoir 4 is set as a "V"-shaped structure, and a button 3 is set on the top surface of the liquid reservoir 4, and the top is threadedly connected to the top of the inner wall of the pen body 1. The "V"-shaped structure helps to ensure that the eyeliner can flow evenly downward along both sides to the first filter layer 41 and be fully filtered by the first filter layer 41, ensuring the uniformity of the eyeliner outflow and the consistency of the application; and the threaded connection allows the liquid reservoir 4 to be separated from the pen body 1, that is, the liquid reservoir 4 can be taken and replaced, which is more convenient for the use of the eyeliner pen.

[0030] A motor 8 is fixedly connected to the inner wall of the bottom of the pen body 1, and the motor 8 is electrically connected to the micro pump 6, the vibrator 7 and the button 3 respectively. The motor 8 is controlled by the button 3, and the motor 8 controls the micro pump 6 and the vibrator 7 to make the entire liquid eyeliner pen form an integrated device to control the flow of the eyeliner liquid, ensure the uniform discharge of the eyeliner pen, and ensure the consistency and uniformity of the applied lines and colors.

[0031] Working principle: When in use, click the button 3 on the top of the liquid storage tank 4, the button 3 connects to the motor 8 and controls it to work, the motor 8 controls the micro pump 6 to enter the working state, the eyeliner liquid in the liquid storage tank 4 flows downward under the action of the micro pump 6, first passes through the first filter layer 41 for preliminary filtration, the filtered eyeliner liquid enters the infusion tube 61 of the micro pump 6, flows through the pump body 62 and enters the discharge pipe 62, and then passes through the second filter layer 91 for secondary filtration, the filtered eyeliner liquid enters the nozzle 9, and is evenly sprayed onto the pen tip 5 through the spray hole 93. The pen tip 5 has a uniform and appropriate amount of eyeliner liquid, and the eyeliner can be drawn at this time.
