Description

Technical Field

[0001] The invention relates to the technical field of cosmetic packaging, in particular to a multifunctional liquid pump head cap. Background Art

[0002] At present, all cosmetic liquid products on the market need to be equipped with a pump head on the bottle, through which the cosmetic liquid in the bottle is pressed out for easy use; this type of pump head uses the principle of air pressure to press the cosmetic liquid out, and the cosmetic liquid is discharged from the pump head cap. Since most of these head caps have a simple structure and no self-sealing function, the liquid is easily left in the head cap after use, causing waste. In addition, the liquid is easily exposed to the air through the head cap and is prone to deterioration, which is easy to cause adverse reactions after use. Therefore, it is necessary to further study and improve this type of head cap structure.

[0003] For example, a Chinese patent document (publication number: CN206701551U) discloses "a switch valve structure for a cosmetic liquid pump", including a pump body, a straw, a piston rod and a head cap. The switch valve structure includes a valve and a spring. The valve can be movably arranged in the head cap at the position of the head cap nozzle. The spring is supported at the rear end of the valve so that the valve has a tendency to always close the nozzle. A liquid storage chamber is provided between the valve and the inner wall of the nozzle. When the head cap is pressed to make the liquid in the liquid storage chamber reach a certain pressure, the valve overcomes the elastic force of the spring and moves backward to open the nozzle.

[0004] In the above scheme, the present invention realizes the closure of the liquid pump in the idle state by setting a valve at the head cap nozzle position, but this scheme additionally increases the manufacturing cost of the liquid pump. In particular, the cost of the micro liquid valve set at the head cap nozzle is higher than the liquid pump itself, which obviously cannot be put into actual production. Therefore, a more feasible solution is needed to solve the above problem. Summary of the invention

[0005] In view of the problem that the pump head of the prior art liquid pump cannot prevent the cosmetics from being affected by the external air and causing oxidation, the present invention provides a multifunctional liquid pump head cap, which maintains the sealing of the discharge nozzle when the user does not press the liquid pump by arranging a reciprocating self-sealing mechanism in the head cap body, has a simple structure, opens and closes synchronously with the pressing action, has high agility, and has low manufacturing cost;

[0006] The second invention of this application aims to solve the problem that when more than one cosmetic liquid passes through a pump head, effective mixing cannot be ensured, thereby affecting the user experience;

[0007] The third invention of the present application aims to solve the problem that when more than one cosmetic liquid is fully mixed, the mixed liquid is easily foamed. When the foamed emulsion is applied, the emulsion is diluted and the nutritional components are uneven, thereby affecting the use effect.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] A multifunctional liquid pump head cap includes a head cap body, a liquid storage portion is arranged in the head cap body, a liquid discharge nozzle is installed in the liquid storage portion, a reciprocating self-sealing mechanism is arranged at the tail of the liquid discharge nozzle, and the reciprocating self-sealing mechanism includes a sealing rod arranged across the liquid storage portion; wherein, the front end of the sealing rod can abut against the liquid channel arranged on the liquid discharge nozzle, the tail end of the sealing rod is provided with a reset member, the side end of the sealing rod is provided with a liquid storage portion connected to the liquid pump, and the sealing rod can reciprocate under the drive of the liquid from the liquid storage portion. In the reciprocating self-sealing mechanism, a sealing rod is used to block the liquid channel set by the liquid discharge nozzle, and the pressure of the cosmetic liquid output by the pump body is cleverly used as the power to drive the sealing rod to open the blockage, without the need to set up an additional power source to drive and control the closed state, and after use, the reset member can be used to restore the closure of the liquid discharge nozzle, which has extremely high agility and ideal actual use effect.

[0010] Preferably, the reciprocating self-sealing mechanism comprises a hydraulic cylinder body inserted in the liquid discharge nozzle, the sealing rod is penetrated in the hydraulic cylinder body, the side of the hydraulic cylinder body is provided with a liquid inlet connected to the liquid pump, and the tail of the hydraulic cylinder body is provided with a limit ring, and the limit ring abuts against the tail end of the liquid discharge nozzle. The hydraulic cylinder body serves as a accommodating component for the sealing rod, and is used to connect the sealing rod with the head cap body. The hydraulic cylinder body and the liquid discharge nozzle are plugged in an interference fit, and the limit ring provided at the tail is used as a limit part for inserting the liquid discharge nozzle, ensuring that the hydraulic cylinder body will not fall into the liquid discharge nozzle and cause the liquid inlet to be blocked, thereby ensuring that the sealing rod can move smoothly under the pressure of the cosmetic liquid.

[0011] Furthermore, the sealing rod includes a sealing section, a pushing section and a resetting section, the sealing section can abut against the discharge nozzle, the pushing section is arranged throughout the hydraulic cylinder body, the liquid inlet is arranged on the side of the pushing section, a sealing ring is arranged between the pushing section and the resetting section, the resetting member is sleeved on the pushing section, and the tail of the resetting member abuts against the side wall of the head cap body. The sealing rod seals and unseals the liquid outlet at the front end of the discharge nozzle through the sealing section, and the pushing section is placed in the liquid storage part of the hydraulic cylinder body, which can convert the pressure of the pumped cosmetic liquid into the power to push the sealing rod to open the liquid outlet backward, and the resetting member assembled on the resetting section can store the pressure provided by the liquid pump, and push the sealing rod to reseal the liquid outlet after the pumping action ends. The sealing rod uses each section to perform corresponding tasks respectively, ensuring that the reciprocating self-sealing mechanism effectively utilizes the pressure provided by the liquid pump, so that the pump head is opened in time when the user uses it, and closed in time after use, thereby avoiding the cosmetics in the bottle from contacting with the air to the greatest extent.

[0012] Preferably, an elastic sealing cover is provided at the rear of the hydraulic cylinder body, and a snap ring groove is provided on the elastic sealing cover, and one end of the reset member away from the side wall of the head cap body is snap-fitted in the snap ring groove. The elastic sealing cover can be partially deformed under the extrusion of the sealing rod, and its edge portion is snap-fitted between the hydraulic cylinder body and the head cap body, while the snap ring groove in the center portion can move forward and backward along the length direction of the sealing rod, ensuring that the reset member remains coaxial with the sealing rod for compression when the sealing rod moves backward, and that the reset member remains on the straight line to release energy and reset when the sealing rod moves forward, so the elastic sealing cover can ensure that the sealing rod maintains a horizontal state and reciprocates.

[0013] Furthermore, a bearing ring is provided near the reset section of the push section, and the bearing ring gradually decreases in diameter from the reset section to the push section. The bearing ring is a truncated cone structure with a gradually decreasing diameter, which better transmits the component force of the hydraulic pressure generated by the liquid pump in the horizontal direction, so that the thrust received by the push section is evenly distributed in the entire circumferential direction, ensuring that the sealing rod moves forward and backward along the central axis.

[0014] Preferably, the pushing section is provided with a clearance ring near the sealing section, and the diameter of the clearance ring gradually decreases from the pushing section to the sealing section. The clearance ring is provided at the port at the front end of the hydraulic cylinder body, and when the sealing rod moves backward, the inclined outer wall of the clearance ring moves backward to make room for the liquid to pass through, so that the liquid in the cosmetic bottle smoothly enters the liquid channel of the discharge nozzle and is discharged outward.

[0015] Preferably, the discharge nozzle is engaged with the inner wall of the head cap body. A positioning ring is provided on the outer wall of the discharge nozzle along the circumferential direction, and a positioning groove is provided on the inner wall of the head cap body corresponding to the positioning ring. The positioning ring is engaged with the positioning groove to ensure that the discharge nozzle remains relatively fixed to the head cap body and will not be loosened by the pressure of the liquid pump, thereby affecting the discharge of liquid.

[0016] Preferably, a liquid mixing mechanism is provided in the liquid discharge nozzle, and the liquid mixing mechanism includes a plurality of mixing sheets arranged in parallel, the mixing sheets include a mixing bottom plate and a receiving groove arranged on the mixing bottom plate, the mixing bottom plate is provided with through holes, and adjacent mixing sheets are connected to each other by the through holes. Considering that there is more than one liquid source in some cosmetics, it is necessary to mix the liquids stored in different liquid cavities before outputting them when using them, so the liquid mixing mechanism can be used to mix a plurality of cosmetic liquids from the liquid pump, and when all kinds of liquids pumped by the liquid pump enter the liquid storage part, they are first preliminarily mixed in the receiving groove of the first mixing sheet, and then the preliminarily mixed liquids are screened and mixed through the through holes of the mixing bottom plate to reach the receiving groove of the second mixing sheet for mixing again, and so on, when reaching the front end of the liquid outlet nozzle through multiple mixing sheets, all kinds of cosmetic liquids have been fully mixed.

[0017] Furthermore, the through holes on adjacent mixing sheets are staggered in the length direction of the liquid discharge nozzle. After various cosmetic liquids are preliminarily mixed in the receiving groove of the first mixing sheet of the liquid mixing mechanism close to the reset member, in order to improve the mixing effect, the through holes of the subsequent mixing sheet and the previous mixing sheet are staggered in the axial direction, so that after the liquid passes through the through hole of the first mixing sheet and enters the receiving groove of the second mixing sheet, it cannot directly enter the through hole of the second mixing sheet under the action of liquid pressure and skip the mixing step, but is forced to mix in the receiving groove and rotate before entering the through hole, thereby significantly improving the mixing effect of different liquids and solving the second invention purpose of this application.

[0018] In particular, the diameter of the sealing section gradually increases from one end close to the driving section to the end away from the driving section. Correspondingly, the inner diameter of the liquid outlet hole of the sealing section corresponding to the liquid outlet nozzle gradually increases from the inside to the outside. This structure enables the cosmetic liquid to generate bubbles through the liquid mixing mechanism, and then effectively eliminate the bubbles through the liquid outlet hole with an increasing inner diameter. The main reason is that the pressure of the liquid decreases when it passes through the liquid outlet hole with an increasing inner diameter at a certain speed, which eliminates the bubbles and foams generated by flowing through the hole due to the pressure reduction, thereby solving the third invention purpose of the present application.

[0019] Therefore, the present invention has the following beneficial effects: (1) by arranging a reciprocating self-sealing mechanism in the main body of the head cap, the sealing of the discharge nozzle is maintained when the user does not press the liquid pump to use it, the structure is simple, the opening and closing are synchronized with the pressing action, the agility is high, and the manufacturing cost is low; (2) the sealing rod uses each section to perform corresponding tasks respectively, ensuring that the reciprocating self-sealing mechanism effectively utilizes the pressure provided by the liquid pump, so that the pump head is opened in time when the user uses it and closed in time after use, thereby avoiding the contact between the cosmetics in the bottle and the air to the greatest extent; (3) the inclined outer wall of the yield ring platform moves backward to leave a gap for the liquid to pass through, so that the liquid in the cosmetic bottle smoothly enters the liquid channel of the discharge nozzle and is discharged outward; (4) the liquid mixing mechanism can be used to perform multiple mixing of more than one cosmetic liquid before leaving the pump head, significantly improving the mixing effect, thereby improving the user experience; (5) the outlet hole with a changing inner diameter is used to reduce the pressure of the cosmetic liquid that generates foam, so that the foam is eliminated after the pressure is lost, thereby improving the uniformity and concentration of the emulsion.

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1

[0026] like Figure 1 As shown in FIG. 2 , a multifunctional liquid pump head cap comprises a head cap body 1, wherein a liquid storage portion 31 is arranged in the head cap body 1, a liquid discharge nozzle 2 is installed in the liquid storage portion 31, a reciprocating self-sealing mechanism 3 is arranged at the tail of the liquid discharge nozzle 2, and the reciprocating self-sealing mechanism 3 comprises a sealing rod 4 arranged across the liquid storage portion 31; wherein, the front end of the sealing rod 4 can abut against the liquid channel arranged on the liquid discharge nozzle 2, a reset member 5 is arranged at the tail end of the sealing rod 4, a liquid storage portion 31 connected to the liquid pump is arranged at the side end of the sealing rod 4, and the sealing rod 4 can reciprocate under the drive of the liquid from the liquid storage portion 31. The reciprocating self-sealing mechanism 3 comprises a hydraulic cylinder body 32 inserted and arranged in the liquid discharge nozzle 2, the sealing rod 4 is arranged through the hydraulic cylinder body 32, a liquid inlet 33 connected to the liquid pump is arranged on the side of the hydraulic cylinder body 32, and a limiting ring 34 is arranged at the tail of the hydraulic cylinder body 32, and the limiting ring 34 abuts against the tail end of the liquid discharge nozzle 2. The liquid discharge nozzle 2 is embedded in the inner wall of the connecting head cap body 1.

[0027] The reciprocating self-sealing mechanism 3 uses a sealing rod 4 to block the liquid channel set by the discharge nozzle 2, and cleverly uses the pressure of the cosmetic liquid output by the pump body as the power to drive the sealing rod 4 to open the blockage. There is no need to set up an additional power source to drive and control the closed state. After use, the reset member 5 can be used to restore the closure of the discharge nozzle 2. It is highly agile and has an ideal actual use effect. The hydraulic cylinder body 32 is used as a accommodating component of the sealing rod 4, which is used to connect the sealing rod 4 with the head cap body 1. The hydraulic cylinder body 32 and the discharge nozzle 2 are interference-connected, and the limiting ring 34 set at the tail is used as a limiting part for inserting the discharge nozzle 2 to ensure that the hydraulic cylinder body 32 will not fall into the discharge nozzle 2 and cause the liquid inlet 33 to be blocked, thereby ensuring that the sealing rod 4 can move smoothly under the pressure of the cosmetic liquid. A positioning ring 22 is circumferentially arranged on the outer wall of the discharge nozzle 2, and a positioning groove is arranged on the inner wall of the head cap body 1 corresponding to the positioning ring. The positioning ring is engaged with the positioning groove to ensure that the discharge nozzle 2 remains relatively fixed to the head cap body 1 and will not loosen due to the pressure of the liquid pump, thereby affecting the liquid discharge.

[0028] like Figure 3 As shown, the sealing rod 4 includes a sealing section 41, a pushing section 42 and a resetting section 43. The sealing section 41 can abut the discharge nozzle 2. The pushing section 42 is arranged throughout the hydraulic cylinder body 32. The liquid inlet 33 is arranged on the side of the pushing section 42. A sealing ring 6 is arranged between the pushing section 42 and the resetting section 43. The resetting member 5 is sleeved on the pushing section 42. The tail of the resetting member 5 abuts against the side wall of the head cap body 1. The sealing rod 4 blocks and unblocks the liquid outlet 21 at the front end of the liquid discharge nozzle 2 through the sealing section 41, and the pushing section 42 is placed in the liquid storage part 31 of the hydraulic cylinder body 32, which can convert the pressure of the pumped cosmetic liquid into the power to push the sealing rod 4 to open the liquid outlet 21 backward, and the reset member 5 assembled on the reset section 43 can store the pressure provided by the liquid pump, and push the sealing rod 4 to reseal the liquid outlet 21 after the pumping action is completed. The sealing rod 4 uses each section to perform corresponding tasks respectively, ensuring that the reciprocating self-sealing mechanism 3 effectively utilizes the pressure provided by the liquid pump, so that the pump head is opened in time when the user uses it, and closed in time after use, thereby avoiding the cosmetics in the bottle from contacting with the air to the greatest extent. In this embodiment, the reset member 5 adopts a compression spring, and the sealing ring 6 adopts a reciprocating dynamic sealing ring 6.

[0029] Furthermore, the pushing section 42 is provided with a load-bearing ring platform 44 near the reset section 43, and the diameter of the load-bearing ring platform 44 gradually decreases from the reset section 43 to the pushing section 42. The pushing section 42 is provided with a yielding ring platform 45 near the sealing section 41, and the diameter of the yielding ring platform gradually decreases from the pushing section 42 to the sealing section 41. The load-bearing ring platform 44 is a truncated cone structure with a gradually decreasing diameter, which better transmits the component of the hydraulic pressure generated by the liquid pump in the horizontal direction, so that the thrust exerted on the pushing section 42 is evenly distributed in the entire circumferential direction, ensuring that the sealing rod 4 moves forward and backward along the central axis. The yielding ring platform 45 is provided at the port at the front end of the hydraulic cylinder body 32. When the sealing rod 4 moves backward, the inclined outer wall of the yielding ring platform 45 makes a gap for the liquid to pass through as it moves backward, so that the liquid in the cosmetic bottle smoothly enters the liquid channel of the discharge nozzle 2 and is output outward.

[0030] In addition, an elastic sealing cover 7 is provided at the tail of the hydraulic cylinder body 32, and a snap-in ring groove 71 is provided on the elastic sealing cover 7, and one end of the reset member 5 away from the side wall of the head cap body 1 is snap-fitted in the snap-in ring groove 71. The elastic sealing cover 7 can be partially deformed under the extrusion of the sealing rod 4, and its edge portion is snap-fitted between the hydraulic cylinder body 32 and the head cap body 1, while the snap-in ring groove 71 in the center portion can move forward and backward along the length direction of the sealing rod 4, ensuring that the reset member 5 is compressed while being coaxial with the sealing rod 4 when the sealing rod 4 moves backward, and the reset member 5 is still kept on the straight line to release energy and reset when the sealing rod 4 moves forward, so the elastic sealing cover 7 can ensure that the sealing rod 4 maintains a horizontal state and reciprocates.

[0031] In this embodiment, when the user presses the self-sealing liquid pump head cap installed on the liquid pump, the liquid enters the liquid storage part 31 from the liquid inlet 33. After the pressurized liquid fills the liquid storage part 31, it naturally pushes the sealing rod 4 backwards, and the elastic sealing cover 7 is compressed by the sealing rod 4 along with the reset member 5. The sealing rod 4 moves backwards to open the liquid passage of the liquid discharge nozzle 2, so that the cosmetic liquid can be pumped out of the head cap smoothly; and when the pressing is completed, the reset member 5 releases the elastic potential energy to push the sealing rod 4 back and close the liquid passage of the liquid discharge nozzle 2 due to the disappearance of the liquid inlet pressure. The pressure provided by the liquid pump is used in conjunction with the elastic force of the reset member 5 to accurately control the opening and closing of the liquid discharge nozzle 2 by the sealing rod 4, which has a simple structure but high sensitivity.

[0032] Example 2

[0033] In this embodiment, a liquid mixing mechanism is provided in the liquid discharge nozzle, and the liquid mixing mechanism includes a plurality of mixing sheets 8 arranged in parallel, the mixing sheet includes a mixing bottom plate and a receiving groove 81 arranged on the mixing bottom plate, the mixing bottom plate is provided with a through hole 82, adjacent mixing sheets are connected to each other by the through hole, and the through holes on adjacent mixing sheets are staggered in the length direction of the liquid discharge nozzle. Considering that there is more than one liquid source in some cosmetics, it is necessary to mix the liquids stored in different liquid cavities before outputting them when using them, so the liquid mixing mechanism can be used to mix a plurality of cosmetic liquids from the liquid pump, and when all kinds of liquids pumped by the liquid pump enter the liquid storage part, they are first preliminarily mixed in the receiving groove of the first mixing sheet, and then the preliminarily mixed liquids are screened and mixed through the through hole of the mixing bottom plate to reach the receiving groove of the second mixing sheet for mixing again, and so on, when reaching the front end of the liquid outlet nozzle through multiple mixing sheets, all kinds of cosmetic liquids have been fully mixed. After various types of cosmetic liquids are preliminarily mixed in the receiving groove of the first mixing piece near the reset piece of the liquid mixing mechanism, in order to improve the mixing effect, the through holes of the subsequent mixing piece and the previous mixing piece are staggered in the axial direction. After the liquid passes through the through hole of the first mixing piece and enters the receiving groove of the second mixing piece, it cannot directly enter the through hole of the second mixing piece under the action of liquid pressure and skip the mixing step. Instead, it is forced to mix and rotate in the receiving groove before entering the through hole, thereby significantly improving the mixing effect of different liquids.

[0034] Example 3

[0035] Different from the above-mentioned embodiment, in this embodiment, the diameter of the sealing section gradually increases from the end close to the driving section to the end far from the driving section. Correspondingly, the inner diameter of the liquid outlet hole of the sealing section corresponding to the liquid outlet nozzle gradually increases from the inside to the outside. This structure enables the cosmetic liquid to generate bubbles through the liquid mixing mechanism, and then effectively eliminate the bubbles through the liquid outlet hole with the gradually increasing inner diameter. The main reason is that the pressure of the liquid decreases when it passes through the liquid outlet hole with the gradually increasing inner diameter at a certain speed, so that the bubbles and foam generated by flowing through the hole are eliminated due to the pressure reduction, which effectively improves the concentration and uniformity of the emulsion.

[0036] In addition to the above-mentioned embodiments, within the scope disclosed in the claims and the specification of the present invention, the technical features of the present invention can be reselected and combined to form new embodiments, which can be achieved by those skilled in the art without creative work. Therefore, these embodiments that are not described in detail in the present invention should also be regarded as specific embodiments of the present invention and within the protection scope of the present invention.
