DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

[0018] like Figures 1 to 8 As shown, a lip balm tube with a high emptying rate described in this embodiment includes a container bottle 1, a container layer 2 arranged in the container bottle 1, and a heating layer 3 arranged between the container bottle 1 and the container layer 2; An induction heating component is provided at the inner bottom of the container bottle 1, and the induction heating component is electrically connected to the heating layer 3; a piston 5 is sealingly and slidably provided inside the container layer 2; a transmission component is provided at the inner bottom of the container layer 2; the transmission component is unidirectionally connected to the induction heating component; the transmission component is connected to the piston 5 to drive the piston 5 to move toward the bottle mouth of the container bottle 1.

[0019] Specifically, in actual application, the lip balm tube of this embodiment drives the heating layer 3 to heat the liquid lipstick inside the container layer 2 by using the induction heating component, so that the viscosity of the internal liquid lipstick is reduced. At the same time, the piston 5 is moved toward the bottle mouth of the container bottle 1 through the transmission component, so that the user can more easily dip the liquid lipstick at the bottom for use, thereby maximizing the emptying rate of the liquid lipstick, reducing waste, and improving the utilization rate of the product.

[0020] like Figure 1 , Figure 4 and Figure 5As shown, the lip balm tube body of this embodiment, in some embodiments, the induction heating component includes an induction coil 41 and two permanent magnets 42 with different polarities and arranged oppositely; the induction coil 41 is rotatably arranged between the two permanent magnets 42; the induction coil 41 is electrically connected to the heating layer 3; the top of the induction coil 41 is connected to the transmission component for one-way transmission; the bottom of the induction coil 41 is connected to a rotating wheel 43; a torsion spring 44 is connected between the rotating wheel 43 and the container bottle 1; a pull rope 45 is wound around the rotating wheel 43; one end of the pull rope 45 is connected to the rotating wheel 43, and the other end of the pull rope 45 moves outward to pass through the container bottle 1.

[0021] In actual use, the user can drive the rotating wheel 43 to rotate by pulling the pull rope 45, so that the torsion spring 44 stores energy, and the rotating wheel 43 drives the induction coil 41 to rotate, so that the induction coil 41 rotates and cuts the magnetic flux lines. In the process of cutting the magnetic flux lines, the induction coil 41 generates an induced current which is transmitted to the heating layer 3, and supplies energy to the heating layer 3 to heat up the heating layer 3. After the heating layer 3 heats up, the liquid lipstick adhered to the inner wall of the container layer 2 is heated, so that the liquid lipstick on the inner wall falls onto the piston 5, and at the same time, the viscosity of the internal liquid lipstick is reduced. When the induction coil 41 rotates, the piston 5 is driven to move through the transmission component to push the liquid lipstick in the container layer 2 to move upward, so that it is convenient for the user to dip the bottom liquid lipstick for use; After the pull rope 45 is loosened, the torsion spring 44 releases the stored energy and drives the rotating wheel 43 to rotate in the opposite direction to reel in the pull rope 45. The rotating wheel 43 drives the induction coil 41 to rotate in the opposite direction, thereby supplying energy to the heating layer 3 again. Since the induction coil 41 rotates in the opposite direction and the induction coil 41 and the transmission assembly are connected in a one-way transmission manner, there is no power transmission between the induction coil 41 and the piston 5 at this time, that is, the piston 5 remains stationary.

[0022] like Figure 1 , Figures 3 to 5 As shown, in the lip balm tube of this embodiment, in some embodiments, the other end of the pull cord 45 is connected with a buckle 46. By providing the buckle 46, the user can operate more conveniently in this embodiment.

[0023] like Figure 1 and Figure 3 As shown, in the lip balm tube of this embodiment, in some embodiments, the side wall of the container bottle 1 is provided with a receiving groove; the pull button 46 is received in the receiving groove. In this embodiment, the receiving groove is provided to provide a receiving space for the pull button 46, making the structure more compact and beautiful.

[0024] like Figure 1 , Figure 6 and Figure 7As shown, the lip balm tube body of this embodiment, in some embodiments, the transmission assembly includes a one-way pawl 63 elastically slidably arranged on the inner bottom of the container layer 2 and a first gear 61 and a second gear 62 rotatably arranged on the inner bottom of the container layer 2; the first gear 61 is meshed with the second gear 62; the one-way pawl 63 is unidirectionally meshed with the second gear 62; the first gear 61 is connected to the induction coil 41 for unidirectional transmission; the shaft neck of the second gear 62 is extended with a screw 64 sealed and passing through the piston 5; the screw 64 is threadedly connected to the piston 5.

[0025] Specifically, when the user pulls the pull cord 45, the induction coil 41 drives the first gear 61 to rotate, the first gear 61 drives the second gear 62 to rotate, the second gear 62 drives the screw 64 to rotate, and the screw 64 drives the piston 5 to push the liquid lipstick in the container layer 2 upward, so that the user can dip the bottom liquid lipstick for use; When the user releases the pull cord 45, the induction coil 41 rotates in the opposite direction. At this time, the one-way pawl 63 locks the second gear 62, making the second gear 62 non-reversible, and the first gear 61 non-reversible, thereby cutting off the power transmission between the induction coil 41 and the piston 5, so that the liquid lipstick in the container layer 2 remains in the current position.

[0026] In this embodiment, a first slide groove is opened at the inner bottom of the container layer 2, a first spring 65 is arranged in the first slide groove, and a one-way pawl 63 is slidably arranged in the first slide groove and connected to the first spring 65; in this way, through the first spring 65, the one-way pawl 63 maintains a tendency of unidirectional meshing with the second gear 62.

[0027] like Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, in the lip balm tube of this embodiment, in some embodiments, the journal of the first gear 61 passes downward through the container layer 2 and is elastically slidably provided with a one-way transmission block 66; the one-way transmission block 66 has a vertical surface 661 and an inclined surface 662; A plurality of transmission bosses 411 are circumferentially arranged on the top of the induction coil 41; when the transmission boss 411 contacts the vertical surface 661, the induction coil 41 drives the first gear 61 to rotate; when the transmission boss 411 contacts the inclined surface 662, the transmission boss 411 squeezes the one-way transmission block 66 and does not drive the first gear 61 to rotate.

[0028] Specifically, when the user pulls the pull rope 45, the induction coil 41 drives the transmission boss 411 to rotate, and when the transmission boss 411 contacts the vertical surface 661 of the one-way transmission block 66, the induction coil 41 cooperates with the transmission boss 411 and the one-way transmission block 66 to push the first gear 61 to rotate, thereby driving the piston 5 to move upward; when the user releases the pull rope 45, the induction coil 41 drives the transmission boss 411 to rotate in the opposite direction, so that the transmission boss 411 contacts the inclined surface 662 of the one-way transmission block 66. At this time, the transmission boss 411 applies an extrusion force to the one-way transmission block 66, causing the one-way transmission block 66 to retract, so that there is no power transmission between the induction coil 41 and the first gear 61.

[0029] In this embodiment, Figure 1 and Figure 7 As shown, the first gear 61 is provided with a second slide groove, a second spring 67 is provided in the second slide groove, and the one-way transmission block 66 slides into the second slide groove and is connected with the second spring 67 .

[0030] like Figure 1 As shown, in the lip balm tube of this embodiment, in some embodiments, a guide column 21 is vertically provided in the container layer 2, and the piston 5 is sealingly and slidably sleeved on the outer wall of the guide column 21. In this embodiment, the guide column 21 is provided to provide guidance for the piston 5, and at the same time, the rotational freedom of the piston 5 is restricted, so that the piston 5 can reliably move upward.

[0031] like Figure 1 , Figure 3 and Figure 6 As shown, the lip balm tube body of this embodiment, in some embodiments, the bottom of the container bottle 1 is detachably connected to the bottom cover 11; the induction heating component is arranged in the bottom cover 11; the bottom end of the screw 64 passes downward out of the container layer 2; the top end of the screw 64 is elastically lifted and connected to a movable rod 68; the movable rod 68 is in contact with the inner top wall of the container layer 2.

[0032] In this embodiment, a detachable bottom cover 11 is provided, so that after the liquid lipstick is used up, the bottom cover 11 can be removed to expose the bottom end of the screw 64, and then the screw 64 is pressed to retract the movable rod 68, and the screw 64 drives the second gear 62 to move upward, so that the second gear 62 is disengaged from the one-way pawl 63. At this time, the piston 5 can be reset to the bottom of the container layer 2, so that the piston 5 can be reset, so that the lip balm tube can be recycled, which is more economical and environmentally friendly.

[0033] Exemplarily, the bottom cover 11 can be connected to the bottom of the container bottle 1 by snap-fitting or threading.

[0034] In this embodiment, Figure 1As shown, a sliding hole is recessed at the top end of the screw rod 64 , a third spring 69 is arranged in the sliding hole, and the movable rod 68 slides into the sliding hole and abuts against the third spring 69 .

[0035] like Figure 1 As shown, in the lip balm tube of this embodiment, in some embodiments, the top surface of the piston 5 is a concave structure 51; with such a configuration, after the liquid lipstick falls into the piston 5, it will condense in the concave part in the center of the piston 5, so that the brush head 73 can always be immersed in the liquid lipstick, thereby improving the dipping effect of the brush head 73.

[0036] like Figure 1 and Figure 8 As shown, the lip balm tube body of this embodiment, in some embodiments, also includes a cover assembly; the cover assembly includes an upper cover 71 and an elastic telescopic rod 72 connected to the center of the inner top wall of the upper cover 71; the bottom end of the elastic telescopic rod 72 is connected to a brush head 73.

[0037] During actual use, the upper cover 71 is closed on the bottle mouth of the container bottle 1, and the elastic telescopic rod 72 drives the brush head 73 to extend into the container layer 2 and abut against the piston 5; after the pull rope 45 is pulled and the heating layer 3 heats the liquid lipstick in the container layer 2, the piston 5 moves upward to push the liquid lipstick upward. At this time, the brush head 73 always abuts against the piston 5, that is, the brush head 73 is always immersed in the liquid lipstick. As the piston 5 moves upward, the elastic telescopic rod 72 contracts and provides elastic force for the brush head 73, so that the brush head 73 remains in contact with the piston 5. At the same time, the upper cover 71 still remains sealed and tightly covered, thereby preventing the moisture in the liquid lipstick from evaporating and drying.

[0038] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the protection scope of the patent application of the present invention.
