[0023] The structural principle and working principle of the present invention are further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-8As shown, the present invention is a concealer bottle with a rotary pump for discharging materials, comprising a bottle body 1, a rotating middle sleeve 2, a rotating shaft 3, a piston 4 and a flexible coating head 5. The rotating middle sleeve 2 can be rotatably installed on the upper end of the bottle body 1, and the rotating shaft 3 extends into the bottle body 1. The upper end of the rotating shaft 3 is fixedly connected to the rotating middle sleeve 2; the rotating shaft 3 is provided with an external thread 31, and the piston 4 is provided with an internal thread 41 matching the external thread 31. The piston 4 is installed outside the rotating shaft 3 and is threadedly matched with the rotating shaft 3. The outer side of the piston 4 slides against the inner wall of the bottle body 1, and the rotating middle sleeve 2 drives When the rotating shaft 3 rotates forward, it can drive the piston 4 to move downward; the rotating shaft 3 is axially provided with a through hole 37 that passes through from top to bottom, and a receiving chamber 6 is formed between the lower side of the piston 4 and the inner wall of the bottle body 1. The receiving chamber 6 is used to receive concealer. The piston 4 and the inner wall of the bottle body 1 have good airtightness to prevent the concealer in the receiving chamber 6 from leaking upward from the outer side of the piston 4. When the piston 4 moves downward, the concealer in the receiving chamber 6 can be pumped and discharged upward along the through hole 37; the flexible coating head 5 is installed on the rotating middle sleeve 2 and is connected to the through hole 37 of the rotating shaft 3. The forward rotation in the embodiment of the present invention refers to clockwise rotation.

[0025] When the present invention is in use, the consumer rotates the rotating middle sleeve 2 in the forward direction. Since the upper end of the rotating shaft 3 is fixedly connected to the rotating middle sleeve 2, the rotating middle sleeve 2 can drive the rotating shaft 3 to rotate in the forward direction. Since the rotating shaft 3 extends into the bottle body 1, the rotating shaft 3 is provided with an external thread 31, and the piston 4 is installed outside the rotating shaft 3 and is threadedly matched with the rotating shaft 3. Therefore, when the rotating shaft 3 rotates in the forward direction, the rotating shaft 3 can drive the piston 4 to move downward. Since the outer side of the piston 4 slides against the inner wall of the bottle body 1, a receiving chamber 6 is formed between the lower side of the piston 4 and the inner wall of the bottle body 1. The receiving chamber 6 is used to receive concealer. The rotating shaft 3 is axially provided with a through hole 37 that passes through from top to bottom. Therefore, when the piston 4 moves downward, the piston 4 can pump the concealer in the receiving chamber 6 to discharge it upward along the through hole 37. Since the flexible coating head 5 is installed on the rotating middle sleeve 2 and is connected to the through hole 37 of the rotating shaft 3, the concealer pumped out from the through hole 37 can be discharged to the flexible coating head 5 for use. It can be seen that the concealer bottle of the present invention is easy to apply, does not need to use a powder puff, can avoid the problem of concealer waste, is convenient and quick to use, and is easy to carry.

[0026] like Figure 3-5 As shown, the rotating shaft 3 extends into the bottle body 1 along the center line of the bottle body 1, so that the rotating shaft 3 can pass through the middle of the piston 4, so that the pressure of the concealer pumped by the piston 4 is balanced. The bottle body 1 is cylindrical in shape, and the piston 4 is circular in shape, so that the inner diameter of the bottle body 1 is consistent from top to bottom, and when the piston 4 moves downward, it can always be close to the inner wall of the bottle body 1.

[0027] like Figure 1-8As shown, the upper end of the bottle body 1 is provided with a bottle mouth 11, and the rotating middle sleeve 2 can be rotatably sleeved outside the bottle mouth 11. The upper end of the rotating shaft 3 is integrally connected with a sleeve 32, and the sleeve 32 is fixedly connected to the inner wall of the rotating middle sleeve 2. The sleeve 32 is provided so that the rotating shaft 3 and the rotating middle sleeve 2 can be fixedly connected. A plurality of clamping blocks 33 are arranged at intervals on the outer wall of the upper end of the sleeve 32 of the rotating shaft 3, and a plurality of clamping grooves 21 that are clamped with the clamping blocks 33 are arranged at intervals on the inner wall of the rotating middle sleeve 2. When installing, the sleeve 32 of the rotating shaft 3 is pushed upward into the inner wall of the rotating middle sleeve 2, and the clamping blocks 33 and the clamping grooves 21 can be stably clamped and fixed.

[0028] like Figure 3-Figure 5 , Figure 7 and Figure 8 As shown, a circle of first latching teeth 34 are evenly spaced on the outer wall of the lower end of the sleeve 32 of the rotating shaft 3, one side of the first latching teeth 34 is a first guide surface 341, and the other side is a first non-return surface 342; the upper end of the bottle mouth 11 of the bottle body 1 is integrally connected with an elastic arm 12, and a second latching tooth 13 is provided on the elastic arm 12, one side of the second latching tooth 13 is a second guide surface 131, and the other side is a second non-return surface 132, the first guide surface 341 corresponds to the second guide surface 131, and the first non-return surface 342 corresponds to the second non-return surface 132 Should cooperate; when the rotating shaft 3 rotates forward, the first guide surface 341 of the first latch tooth 34 can slide through the second guide surface 131 of the second latch tooth 13 and force the elastic arm 12 to elastically deform downward until the first guide surface 341 passes over the second guide surface 131, and the elastic arm 12 elastically resets upward; when the rotating shaft 3 rotates reversely, the second check surface 132 of the second latch tooth 13 can block the first check surface 342 of the first latch tooth 34, so that the rotating shaft 3 cannot rotate reversely, and prevent the outside air from entering the accommodating cavity along the through hole of the rotating shaft. The reverse rotation in the embodiment of the present invention refers to counterclockwise rotation. Preferably, the first guide surface 341 and the second guide surface 131 are inclined surfaces respectively, and the first check surface 342 and the second check surface 132 are vertical surfaces respectively; the number of the first latch teeth 34 is 12, the number of the elastic arms 12 and the second latch teeth 13 are two respectively, and the positions of the two second latch teeth 13 are opposite.

[0029] like Figure 3-Figure 6 , Figure 8 As shown, the lower end of the bottle mouth 11 of the bottle body 1 is integrally connected with a snap ring 14, and the inner wall of the lower end of the rotating middle sleeve 2 is provided with an annular snap groove 22, and the snap ring 14 can be rotatably snapped into the annular snap groove 22. The upper side of the snap ring 14 is chamfered, and the lower edge of the inner wall of the rotating middle sleeve 2 is also chamfered, so that the snap ring 14 can be snapped into the annular snap groove 22 with force, and the structure in which the snap ring 14 and the annular snap groove 22 are matched can make the rotating middle sleeve 2 rotate stably.

[0030] like Figure 2-Figure 5 , Figure 7 As shown, a positioning cavity 35 is provided at the upper end of the sleeve 32 of the rotating shaft 3, and a discharge pipe 36 connected to the through hole 37 is provided in the middle of the positioning cavity 35. A connecting hole 23 is provided at the top of the rotating middle sleeve 2, and an annular connecting groove 51 is provided on the outer side of the flexible coating head 5, which is engaged with the connecting hole 23. The lower end of the flexible coating head 5 is accommodated in the positioning cavity 35, and the discharge pipe 36 is inserted upward into the flexible coating head 5. The flexible coating head 5 is a sponge head, and the upper end of the flexible coating head 5 is hemispherical. The concealer bottle also includes an upper cover 7, which covers the outside of the flexible coating head 5, and the lower inner wall of the upper cover 7 is detachably connected to the upper outer wall of the rotating middle sleeve 2.
