Description

Technical Field

[0001] This application relates to the field of cosmetic technology, and in particular to a lip gloss device. Background Technology

[0002] Lip gloss is a type of lip cosmetic. It is a liquid lipstick that is moisturizing, glossy, and easy to apply. Lip gloss has a thick texture and a similar appearance to lip tint. It is an upgraded version of lip tint and a combination of lipstick and lip gloss.

[0003] In related technologies, lip gloss typically consists of three parts: the bottle, the brush, and the cap. The bottle contains the lip gloss product. To use it, the cap needs to be unscrewed, and the product needs to be manually stirred at an angle inside the bottle to allow the brush tip to pick up the product. Then, the entire brush tip is pulled out. This process is not only laborious but also prone to causing the brush tip to deviate from the bottle opening when inserting or removing the cap, resulting in lip gloss getting onto the bottle or fingers. Furthermore, the lip gloss product located higher up in the bottle is difficult to use fully, leading to waste. Utility Model Content

[0009] In some embodiments of this application, the first sleeve has two vertical strip grooves at opposite positions, and the inner wall of the second sleeve has two spiral grooves with the same direction of rotation at opposite positions; a brush rod base is provided at the bottom of the brush rod; a pin protruding from the brush rod base is provided on each side of the brush rod base, and the pin is slidably connected to the strip groove and the spiral groove in sequence; when the lower housing drives the first sleeve to rotate relative to the second sleeve along the axis, the pin can drive the brush rod base to spirally rise or fall along the spiral groove and rise or fall along the strip groove, so that the brush rod can rise and fall relative to the second sleeve and rotate along the axis.

[0010] In some embodiments of this application, the bottom of the first sleeve is provided with a first annular boss; the first annular boss engages with the inner wall of the lower housing so that the first sleeve can rotate with the lower housing; the bottom of the upper housing is provided with a second opening; the top of the second sleeve passes through the second opening and engages with the inner wall of the upper housing so that the second sleeve can remain relatively stationary when the lower housing rotates; the bottom of the second sleeve abuts against the first annular boss.

[0011] In some embodiments of this application, the lip gloss device further includes a first rubber stopper; a second annular protrusion facing inward is provided on the inner sidewall of the top of the second sleeve; the first rubber stopper is fixedly disposed at the center of the second annular protrusion; a through hole is provided at the center of the first rubber stopper, and the brush rod passes through the through hole of the first rubber stopper, so that the brush head and stirring structure are located in the upper cavity; the diameter of the through hole of the first rubber stopper is the same as the diameter of the brush rod, so that the first rubber stopper seals the bottom of the upper cavity.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0039] As mentioned in the background section, lip gloss is a type of lip cosmetic. It is a liquid lipstick that is moisturizing, glossy, and easy to apply. Lip gloss has a viscous texture and a similar appearance to lip tint. It is an upgraded version of lip tint and a combination of lipstick and lip gloss.

[0040] In related technologies, lip gloss typically consists of three parts: the bottle, the brush, and the cap. The bottle contains the lip gloss product. To use it, the cap needs to be unscrewed, and the product needs to be manually stirred at an angle inside the bottle to allow the brush tip to pick up the product. Then, the entire brush tip is pulled out. This process is not only laborious but also prone to causing the brush tip to deviate from the bottle opening when inserting or removing the cap, resulting in lip gloss getting onto the bottle or fingers. Furthermore, the lip gloss product located higher up in the bottle is difficult to use fully, leading to waste.

[0041] To reduce hand movements when applying lip gloss and removing the brush, prevent lip gloss from getting on the bottle or fingers, and avoid wasting lip gloss, this application provides a lip gloss device, which will be described in detail below.

[0042] See Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of the lip gloss device according to an embodiment of this application; Figure 2 This is a schematic diagram of the lip gloss device in use according to an embodiment of this application; Figure 3 for Figure 1 A cross-sectional view of the lip gloss device shown. Figure 4 for Figure 2 A cross-sectional view of the lip gloss device shown.

[0043] like Figures 1 to 4 As shown, the lip gloss device includes: an upper housing 10, a lower housing 20, and a rotating assembly 30; the lower housing 20 is disposed at the bottom of the upper housing 10 and is capable of rotating relative to the upper housing 10 along an axis.

[0044] The upper housing 10 has a first opening 111 at its top, and its interior space forms an upper cavity 100. The lower housing 20 has a lower cavity 200 inside its interior space. A liftable brush rod 40 is provided inside the lower cavity 200. The brush rod 40 is connected to the lower housing 20 via a rotating assembly 30, and can be raised and lowered relative to the upper housing 10 and rotated along the axis under the rotation of the lower housing 20.

[0045] A brush head 41 is provided at the top of the brush rod 40, and the brush head 41 extends upward into the interior of the upper cavity 100. The brush rod 40 located inside the upper cavity 100 has a stirring structure 42 provided on its outer wall.

[0046] As the brush handle 40 rises, the brush head 41 picks up the lip gloss from inside the upper cavity 100, passes through the first opening 111, and extends to the outside of the upper cavity 100. As the brush handle 40 rotates, the stirring structure 42 can stir the lip gloss inside the upper cavity 100.

[0047] This application provides a lip gloss device in which the brush handle 40 can move up and down relative to the upper housing 10 and rotate along the axis under the rotation of the lower housing 20. When using the lip gloss device, simply rotating the lower housing 20 allows the brush head 41 to pick up the lip gloss inside the upper cavity 100 and extend it out of the upper cavity 100, reducing the hand action of picking up the lip gloss and pulling out the brush head 41, and preventing the brush head 41 from deviating from the bottle opening and causing the lip gloss to stick to the bottle or fingers. In addition, the brush handle 40 located inside the upper cavity 100 has a stirring structure 42 on its outer wall. When the lower housing 20 is rotated, the stirring structure 42 rotates with the brush handle 40, which can stir the lip gloss inside the upper cavity 100. This can prevent the lip gloss from solidifying and can also stir and scrape down the lip gloss located at the higher position of the upper cavity 100 for full use, avoiding waste of lip gloss. The handle 40 is always inside the lip gloss device. Compared with the existing technology that pulls the entire handle out of the bottle, it is more labor-saving, convenient and easy to operate. It also avoids the lip gloss from being contaminated when the handle 40 is retracted into the bottle after contact with the external environment, and can also achieve the effect of keeping hands dry and clean.

[0048] Specifically, such as Figure 1 and Figure 3 As shown, the lip gloss device also includes a dust cover 60, which is joined to the lower housing 20 to form the outer shell of the lip gloss device. The outer shell of the lip gloss device can be as follows: Figure 1 and Figure 3As shown, the outer shell of the lip gloss device is cylindrical. In other embodiments of this application, the outer shell of the lip gloss device may also be prismatic or other shapes, and this application is not limited to this. Furthermore, multiple recessed areas are provided on the outer walls of both the dust cover 60 and the lower shell 20 to make the outer shell of the lip gloss device have a wavy outline, which is used for anti-slip and can improve the comfort of the hand when holding the shell.

[0049] When using the lip gloss device, first remove the dust cover 60, hold the upper housing 10, and rotate the lower housing 20 so that the brush head 41 of the brush 40 dips into the lip gloss inside the upper cavity 100 and extends out from the first opening 111; after use, rotate the lower housing 20 in the opposite direction so that the brush head 41 of the brush 40 retracts into the upper cavity 100.

[0050] It should be noted that the upper housing 10 and the lower housing 20 are coaxial, and the brush rod 40 and the first opening 111 are both located on this axis, so that the brush rod 40 can be smoothly raised and lowered to extend or retract into the upper cavity 100.

[0051] like Figure 3 and Figure 4 As shown, the upper part of the side wall of the upper housing 10 is conical, and the lower part is cylindrical. This design makes the outer contour of the lip gloss device smoother. In addition, the upper part is conical, which helps to intercept excess lip gloss in the upper cavity 100 during the brush head 41's ascent, thus avoiding waste caused by excessive brush head 41 picking up too much product.

[0052] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the stirring structure 42 is a spring 42A. The spring 42A is fixedly sleeved on the brush rod 40. The method of fixing the spring 42A to the brush rod 40 is not limited in this application; it can be adhesive bonding or... Figure 3 and Figure 4 The card connection shown.

[0053] The lower diameter of spring 42A is larger than the upper diameter, allowing spring 42A to rotate with brush rod 40 and stir the lip gloss inside upper cavity 100. In this embodiment, spring 42A is used as the stirring structure 42, resulting in a simple structure and easy assembly. Furthermore, the larger contact area between spring 42A and the lip gloss ensures more thorough stirring.

[0054] In some embodiments of this application, see Figure 5 and Figure 6 , Figure 5 for Figure 3 A perspective view of the first embodiment of the brush rod shown; Figure 6 for Figure 3 A perspective view of the second embodiment of the brush handle shown. Figures 3 to 6As shown, the stirring structure 42 may also replace the spring 42A with the stirring paddle 421 instead of the spring 42A, as will be explained below.

[0055] like Figure 6 As shown, the stirring structure 42 includes multiple stirring paddles 421, which are spaced apart around the brush rod 40. The multiple stirring paddles 421 can rotate with the brush rod 40 to stir the lip gloss inside the upper cavity 100. The stirring paddles 421 can be integrally formed with the brush rod 40, or they can be manufactured separately and then fixedly connected.

[0056] By applying the embodiments of this application, by setting multiple stirring paddles 421, the brush rod 40 can stir the lip gloss in the upper cavity 100 when it rotates. This can prevent the lip gloss from solidifying and can also stir and scrape down the lip gloss located at a higher position in the upper cavity 100 for full use, thus avoiding waste of the lip gloss. In addition, the stirring structure 42 has a simple and lightweight structure and occupies little space.

[0057] Specifically, the stirring paddle 421 can be blade-shaped, frame-shaped, or spiral-shaped, etc., and its shape and quantity are not limited in this application. Figure 6 In the embodiment shown, the stirring paddle 421 is a straight blade, and there are 4 of them. The 4 stirring paddles 421 are evenly spaced around the outer wall of the brush rod 40.

[0058] When using the impeller 421, multiple sets of stirring structures 42 can be configured. For example, Figure 6 The four stirring paddles 421 shown form a stirring structure 42, and multiple stirring structures 42 can be arranged vertically and horizontally along the brush rod 40. By applying the embodiments of this application and setting multiple stirring structures 42, the stirring efficiency can be improved, resulting in more thorough stirring.

[0059] The lengths of the stirring paddles 421 in a set of stirring structures 42 can be the same or different, but the lengths must meet the requirement that the outer diameter of the brush rod 40 at the stirring structure 42, that is, the sum of the diameter of the brush rod 40 and the lengths of the two stirring paddles 421 on both sides in the cross section, is not greater than the inner diameter of the top of the upper shell 10, so that the stirring structure 42 can follow the brush rod to a higher position in the upper cavity 100 and fully stir the lip gloss at that position.

[0060] When there are multiple sets of stirring structures 42, the outer diameter of the brush rod 40 at each stirring structure 42 can be gradually increased from high to low, which can further improve the stirring effect.

[0061] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the top of the brush handle 40 is provided with a slot 45, and the bottom of the brush head 41 is inserted into the slot 45, which is detachably connected to the handle 40.

[0062] Specifically, the slot 45 extends vertically, and its cross-sectional shape can be square, circular, or other shapes, which are not limited in this application. The bottom cross-sectional shape of the brush head 41 is the same as that of the slot 45.

[0063] In the embodiments of this application, the brush head 41 and the brush handle 40 are detachably connected, so that the lip gloss device can be replaced after the brush head 41 becomes dirty or damaged, thereby improving the service life of the lip gloss device.

[0064] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the rotating assembly 30 is disposed in the lower cavity 200 and includes: a first sleeve 31 and a second sleeve 32.

[0065] The first sleeve 31 is fixedly connected to the bottom of the lower housing 20, and the brush rod 40 is partially disposed inside the first sleeve 31 and is connected to the first sleeve 31 in a transmission manner.

[0066] The second sleeve 32 is fitted outside the first sleeve 31, and its top is fixedly connected to the upper housing 10.

[0067] Driven by the rotation of the lower housing 20, the first sleeve 31 can drive the brush rod 40 to rise and fall relative to the second sleeve 32 and rotate along the axis.

[0068] In this embodiment, the first sleeve 31 is fixedly connected to the lower housing 20, and the second sleeve 32 is fixedly connected to the upper housing 10. When using the lip gloss device, holding the upper housing 10 restricts the rotation of the second sleeve 32, while rotating the lower housing 20 causes the first sleeve 31 to rotate, thus reducing the need for hand movements to pick up lip gloss and pull out the brush head 41. This prevents the brush head 41 from deviating from the bottle opening, which could result in lip gloss getting on the bottle or fingers. The coaxial nesting arrangement of the first sleeve 31, the second sleeve 32, and the lower housing 20 improves the utilization of the space in the lower cavity 200, making the structure of the lip gloss device more compact.

[0069] In some embodiments of this application, see Figures 7 to 12 , Figure 7 for Figure 3 A three-dimensional view of the first sleeve shown; Figure 8 for Figure 7 A cross-sectional view of the first sleeve shown; Figure 9 for Figure 3 A three-dimensional view of the second sleeve shown; Figure 10 for Figure 9 A cross-sectional view of the second sleeve shown; Figure 11 for Figure 3 The sectional view of the upper shell shown; Figure 12 for Figure 3 The image shows a sectional view of the lower housing. Figure 3 , Figure 4 , Figures 7 to 10 As shown, the bottom of the first sleeve 31 is provided with a first annular boss 312; the first annular boss 312 is engaged with the inner wall of the lower housing 20 so that the first sleeve 31 can rotate with the lower housing 20.

[0070] The bottom of the upper housing 10 is provided with a second opening 112; the top of the second sleeve 32 passes through the second opening 112 and engages with the inner wall of the upper housing 10 so that the second sleeve 32 can remain relatively stationary when the lower housing 20 rotates; the bottom of the second sleeve 32 abuts against the first annular boss 312.

[0071] Specifically, such as Figure 7 and Figure 8 As shown, the bottom section of the first sleeve 31 protrudes outward to form a first annular boss 312, which is engaged with the inner wall of the bottom of the lower housing 20. The interior of the first annular boss 312 is used to accommodate the brush rod base 43, and the upper surface of the first annular boss 312 is used to limit the second sleeve 32 in the vertical direction.

[0072] By applying the embodiments of this application, a first annular boss 312 is provided at the bottom of the first sleeve 31. The first sleeve 31 can be engaged with the lower housing 20 and the second sleeve 32 can be longitudinally limited without the need to add anti-rotation components and limiting components, making the structure of the lip gloss device simple and compact.

[0073] like Figure 7 and Figure 11 As shown, the first annular boss 312 is provided with a plurality of first protrusions 3121, which are spaced apart around the outer wall of the first annular boss 312 to form a plurality of first grooves 3122. Correspondingly, a plurality of first anti-rotation blocks 210 are provided at the bottom of the inner wall of the lower housing 20.

[0074] When connecting the first sleeve 31 to the lower housing 20, the first sleeve 31 is inserted into the lower cavity 200, so that each of the first anti-rotation blocks 210 is inserted into the corresponding first groove 3122 to achieve a snap-fit. Both sides of each first anti-rotation block 210 are in contact with the first protrusion 3121, thereby preventing the first sleeve 31 and the lower housing 20 from rotating relative to each other.

[0075] like Figure 9 and Figure 12 As shown, the second sleeve 32 and the upper housing 10 are engaged in the same manner. Specifically, the bottom of the inner wall of the upper housing 10 is provided with a plurality of second protrusions 121, which are spaced apart around the inner wall of the upper housing 10 to form a plurality of second grooves 122. Correspondingly, a plurality of second anti-rotation blocks 325 are provided on the outer wall of the top end of the second sleeve 32.

[0076] When connecting the second sleeve 32 to the upper housing 10, the upper housing 10 is fitted onto the top of the second sleeve 32, so that each of the second anti-rotation inserts 325 is inserted into the corresponding second groove 122 to achieve a snap-fit. Both sides of each second anti-rotation insert 325 are in contact with the second protrusion 121, thereby preventing relative rotation between the second sleeve 32 and the upper housing 10.

[0077] It should be noted that this application does not limit the number of each protrusion and anti-rotation block, as long as the number of anti-rotation blocks is not greater than the number of protrusions.

[0078] like Figure 3 , Figure 4 , Figure 9 and Figure 10 As shown, in the section where the second sleeve 32 engages with the inner wall of the upper housing 10, an annular sealing groove 323 is provided on the outer wall of the second sleeve 32. A sealing ring 324 is correspondingly provided in the annular space formed by the sealing groove 323 and the inner wall of the upper housing 10. The sealing ring 324 is made of silicone or rubber, etc., and its outer diameter can be set to be slightly larger than the diameter of the second opening 112, for sealing and fastening the connection between the second sleeve 32 and the upper housing 10.

[0079] In some embodiments of this application, such as Figure 3 , Figure 4 , Figures 7 to 10 As shown, the first sleeve 31 has two vertical strip grooves 311 in opposite positions, and the strip grooves 311 are through grooves that penetrate the cylinder wall of the first sleeve 31. The inner wall of the second sleeve 32 has two spiral grooves 321 with the same direction of rotation in opposite positions.

[0080] The bottom of the brush rod 40 is provided with a brush rod base 43; on both sides of the brush rod base 43, there is a pin 44 protruding from the brush rod base 43, and the pin 44 is slidably connected to the strip groove 311 and the spiral groove 321 in sequence.

[0081] When the lower housing 20 drives the first sleeve 31 to rotate relative to the second sleeve 32 along the axis, the pin 44 can drive the brush rod base 43 to spiral up or down along the spiral groove 321 and up or down along the strip groove 311, so that the brush rod 40 can rise and fall relative to the second sleeve 32 and rotate along the axis.

[0082] Specifically, such as Figure 3 and Figure 4 As shown, the pins 44 on both sides of the brush rod base 43 correspond to the strip grooves 311 on both sides of the first sleeve 31 and the spiral grooves 321 on both sides of the inner wall of the second sleeve 32, respectively. The outer diameter of the brush rod base 43 is not greater than the inner diameter of the first sleeve 31. When the brush rod 40 is in the lowest position, the brush rod base 43 is in contact with the top surface of the bottom plate of the lower housing 20.

[0083] In the embodiments of this application, a spiral groove 321 is provided on the inner wall of the second sleeve 32, and a strip groove 311 is provided on the first sleeve 31; a brush rod base 43 with a pin 44 is provided at the bottom of the brush rod 40. The pin 44 is slidably connected to the strip groove 311 and the spiral groove 321 in sequence. The movement of the pin 44 can be controlled by rotating the lower housing 20, thereby controlling the lifting and lowering of the brush rod 40, making the lip gloss device compact and easy to operate.

[0084] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the lip gloss device also includes a first rubber stopper 51.

[0085] On the inner side wall of the top of the second sleeve 32, there is a second annular boss 322 facing inward; the first rubber plug 51 is fixedly disposed at the center of the second annular boss 322.

[0086] The first rubber stopper 51 has a through hole in the center, and the brush rod 40 passes through the through hole of the first rubber stopper 51, so that the brush head 41 and the stirring structure 42 are located in the upper cavity 100; the diameter of the through hole of the first rubber stopper 51 is the same as the diameter of the brush rod 40, so that the first rubber stopper 51 seals the bottom of the upper cavity 100.

[0087] Specifically, such as Figure 10 As shown, a second annular boss 322 protruding inward is provided above the spiral groove 321, forming a stepped hole on the inner side of the top of the second sleeve 32. The diameter of the hole above the second annular boss 322 is larger than the inner diameter of the second annular boss 322. The outer contour shape of the first rubber stopper 51 matches the shape of the stepped hole, forming an I-shape, to be secured to the top of the second sleeve 32. The upper and lower end faces of the second annular boss 322 are used to limit the first rubber stopper 51 in the vertical direction.

[0088] The outer diameter of the first rubber plug 51 can be set to be slightly larger than the inner diameter of the second annular boss 322, so that the first rubber plug 51 is locked onto the second annular boss 322.

[0089] like Figure 3 As shown, when the brush rod 40 is in its lowest position, the spring 42A is compressed, and its bottom abuts against the top of the first rubber stopper 51. Figure 4 As shown, when the brush rod 40 is in the highest position, the brush rod base 43 abuts against the bottom surface of the first rubber plug 51.

[0090] In the embodiment of this application, a first rubber stopper 51 is provided at the top of the second sleeve 32. The brush rod 40 always seals the through hole of the first rubber stopper 51, separating the upper cavity 100 and the lower cavity 200, thus preventing the lip gloss from flowing from the upper cavity 100 to the lower cavity 200.

[0091] The through-hole shape of the first rubber stopper 51 can be cylindrical or, as shown in the figure, it can be... Figure 3 and Figure 4 The funnel shape shown has a gradually decreasing diameter of the through-hole from top to bottom, forming a beveled surface. When the brush handle 40 descends, this beveled surface acts as a guide, preventing excess lip gloss from being scraped off and accumulating in the through-hole.

[0092] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the lip gloss device also includes a second rubber stopper 52. The second rubber stopper 52 is fixedly disposed in the first opening 111, and has a through hole in the center.

[0093] The diameter of the through hole of the second rubber plug 52 is the same as the diameter of the brush rod 40, so that when the brush head 41 extends through the second rubber plug 52 to the outside of the upper cavity 100, the second rubber plug 52 can seal the top of the upper cavity 100.

[0094] Specifically, such as Figure 12 As shown, the inner wall of the upper housing 10 near the top is provided with a third annular boss 113 that protrudes inward, so that the first opening 111 is formed as a stepped hole. The diameter of the hole above the third annular boss 113 is larger than the inner diameter of the third annular boss 113. The outer contour shape of the second rubber stopper 52 matches the shape of the first opening 111 to lock into place. The upper and lower end faces of the third annular boss 113 are used to limit the second rubber stopper 52 in the vertical direction.

[0095] The dimensions of spring 42A satisfy that the upper diameter is greater than the through-hole diameter of the second rubber plug 52 and the lower diameter is greater than the through-hole diameter of the first rubber plug 51, so as to ensure that spring 42A is always located in the upper cavity 100.

[0096] When the brush head 41 extends through the second rubber stopper 52 to the outside of the upper cavity 100, the brush rod 40 fills the through hole of the second rubber stopper 52, so that the second rubber stopper 52 is sealed. External air or dust cannot enter the upper cavity 100, and the lip gloss inside the upper cavity 100 cannot flow out from the first opening 111, which can prevent leakage and avoid the lip gloss from being contaminated or solidified.

[0097] In some embodiments of this application, see Figure 13 , Figure 13 for Figure 3 The image shows a cross-sectional view of the dust cover. Figure 3 , Figure 4 and Figure 13As shown, the dust cover 60 is sleeved on the outside of the upper housing 10 and is detachably connected to the upper housing 10. A sealing plug 61 protruding towards the first opening 111 is provided on the top of the dust cover 60 to seal the through hole of the second rubber plug 52.

[0098] Specifically, such as Figure 3 As shown, the dust cover 60 and the upper housing 10 are connected by a vertical plug-in connection. In other embodiments of this application, both the bottom outer wall of the upper housing 10 and the inner wall of the dust cover 60 may be provided with threads, allowing the dust cover 60 to be tightened or loosened by rotating it, thus putting on or removing the dust cover 60. This application does not limit the detachable connection method between the upper housing 10 and the dust cover 60.

[0099] The outer diameter of the sealing plug 61 is not less than the diameter of the through hole of the second rubber plug 52, and the length of the sealing plug 61 in the vertical direction is not limited in this application.

[0100] By applying the embodiments of this application, the lip gloss in the upper cavity 100 can be prevented from solidifying or becoming contaminated due to contact with outside air or dust when the lip gloss device is not used for a long time.

[0101] If the sealing plug 61 only seals the top of the through hole of the second rubber plug 52, when the lip gloss device is in Figure 3 When the device is not in use, a large amount of lip gloss accumulates above the brush head 41. The lip gloss forms a tension surface in the upper cavity 100, blocking the first opening 111. If the lip gloss device is to be used at this time, when the dust cover 60 is removed and the brush bar 40 is rotated and raised, there is a problem of lip gloss above the brush head 41 being carried out of the upper cavity 100, resulting in waste.

[0102] To solve the above problems, such as Figure 3 and Figure 13 As shown, the sealing plug 61 can be set to be relatively long in the vertical direction, passing through the first opening 111 and extending into the middle of the upper cavity 100. The sealing plug 61 and the brush rod 40 are on the same axis, and there is a certain gap between the sealing plug 61 and the brush rod 40.

[0103] When the lip gloss device is in Figure 3 When the device is not in use, the presence of the sealing plug 61 prevents a large amount of lip gloss from accumulating above the brush head 41. If the lip gloss device is to be used, the dust cover 60 is removed. The original position of the sealing plug 61 is not immediately filled with lip gloss, leaving a channel in the position. This prevents the lip gloss from closing in the upper cavity 100 and forming a tension surface that blocks the first opening 111. When the brush bar 40 is rotated and raised, the amount of lip gloss carried out is also small due to the small amount of lip gloss above the brush head 41, thus avoiding waste.

[0104] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
