DETAILED DESCRIPTION

[0026] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figure 1 As shown, a conveniently replaceable rotating liquid container, the main body 100 includes an inner bottle 220 and an outer bottle 130, the inner bottle 220 is used to store materials, and the outer bottle 130 is connected to the inner bottle 220 as a liquid discharge device.

[0029] like Figure 4 As shown, the inner bottle 220 is provided with a material cavity 221 for containing liquid, and the material cavity 221 passes through downward, and the upper end of the inner bottle 220 is a liquid outlet. The bottom of the material cavity 221 is connected to a piston 230 and a bottom film 240. The opening of the material cavity 221 of the piston 230 is placed inside, and is interference fit with the inner wall of the material cavity 221 to form a sealing structure. A hollow space that can hold liquid is formed inside the material cavity 221. The piston 230 can push the liquid content upward as the liquid in the material cavity 221 is consumed and discharged. The bottom film 240 is fixedly matched with the opening of the lower end wall of the material cavity 221. Two through holes are also provided on the bottom film 240 to keep the space between the piston 230 and the bottom film 240 connected to the outside atmosphere.

[0030] like Figure 2-3 As shown, the upper end of the inner bottle 220 has an inner bottle connector 210. When stored as a separate packaging kit, a plurality of guide cylinders 211 are provided on the outer wall of the inner bottle connector 210. In the present application, three guide cylinders 211 are provided. The inner bottle 220 also includes an inner bottle cap 250. The inner bottle cap 250 is fixedly connected to the three guide cylinders 211 through three buckles provided on its inner wall to seal the contents of the inner bottle 220.

[0031] When the inner bottle 220 and the outer bottle 130 are connected, the inner bottle cap 250 needs to be removed.

[0032] The outer bottle 130 is provided with a connecting cavity 130-8 for connecting to the inner bottle 220. When the outer bottle 130 and the inner bottle 220 are connected, the inner bottle 220 extends into the connecting cavity 130-8 from the bottom. The upper end of the connecting cavity 130-8 is provided with a connecting wall 1310. The connecting wall 1310 extends out of the connecting cavity 130-8. The side wall of the connecting wall 1310 is provided with a penetrating guide port 130-2. When the inner bottle 220 and the outer bottle 130 are connected, the guide cylinder 211 will pass through the guide port 130-2 to form a preliminary connection.

[0033] The inner wall of the connecting wall 1310 is provided with an annular platform 130-1 at the upper end of the guide port 130-2, and the annular platform 130-1 is connected to the pump core 140. The pump core 140 is used to control the pumping out of the solution in the inner bottle 220. The lower end of the pump core 140 passes through the annular platform 130-1 and is connected to the inner bottle connector 210. The upper end of the pump core 140 extends out of the connecting wall 1310 and is connected to the head cap 110. The pump core 140 is controlled by pressing the head cap 110 to control the discharge of the solution. When the head cap 110 is pressurized, the pump core assembly 140 is compressed or decompressed by the internal spring structure to form an internal vacuum, thereby sucking up the liquid in the inner bottle 220 and transporting it to the head cap 110 for discharge.

[0034] like Figure 5-7 As shown, the outer bottle 130 is further connected to a rotating member 120 , and the rotating member 120 is provided with a guide groove 121 for clamping the guide cylinder 211 , and the inner bottle 220 is further locked by the rotating member 120 .

[0035] A vertical wall 1330 is provided on the outermost side of the outer bottle 130, and a mark 130-6 is provided on the outer side of the vertical wall 1330. The mark includes locked and unlocked. The through hole 126 indicating the position on the rotating member 120 is matched with the through hole 126 and the two marks 130-6 by rotating the rotating member 120 forward and reverse, so that the user can observe the locking status of the container conveniently.

[0036] The outer bottle 130 is further provided with an inner annular wall 1320 . The inner annular wall 1320 is located between the connecting wall 1310 and the outer wall 1330 . The inner annular wall 1320 is connected to the rotating member 120 when in use.

[0037] The rotating member 120 and the guide cylinder 211 of the inner bottle 220 are not fixedly connected. An inner vertical wall 123 is connected to the rotating member 120. The connection between the inner vertical wall 123 and the rotating member 120 is not limited. The rotating member 120 can drive the inner comb wall 123 to rotate. In the present application, the inner vertical wall 123 and the rotating member 120 are plug-in. The inner vertical wall 123 is provided with a guide groove 121. The number of guide grooves 121 and the guide cylinder 211 corresponds one to one, which facilitates the connection of the guide cylinder 211. The guide groove 121 is an upward inclined groove. When the rotating member 120 drives the inner vertical wall 123 to rotate, the guide port 130-2 limits the rotation of the guide cylinder 211. The guide groove 121 contacts the guide cylinder 211 and drives the guide cylinder 211 to move the inner bottle vertically upward.

[0038] At the same time, the rotating member 120 is set as a stepped cone, and an annular protrusion 128 is provided on the lower side of the inner wall of the rotating member 120. The annular protrusion 128 and the inner wall of the rotating member 120 form an annular groove 129, and an annular buckle 1350 is provided on the outer wall of the outer bottle 130. When the rotating member 120 and the outer bottle 130 are connected, the annular buckle 1350 is stuck in the annular groove 129 to achieve locking of the up and down movement, limit separation, and do not affect the rotation of the outer bottle 130.

[0039] At the same time, a baffle 124 is fixedly installed on the outer wall of the inner vertical wall 124, and a limiting rib 125 is connected to the lower part of the baffle 124. The limiting rib 125 and the baffle 124 correspond to each other one by one, and there are three groups of them, which are respectively arranged on one side of the guide groove 121. At the same time, the inner ring wall 1320 is provided with a notch 130-7, and the notch 130-7 is used to accommodate the baffle 124. At the same time, the inner ring wall 1320 is also provided with a convex rib 130-5 for abutting the limiting rib 125, and the convex ribs also include a left convex rib 130-3 and a right convex rib 130-4. There is a certain gap between the side wall of the opening 130-7 and the rib 130-5. When the rotating member 120 and the outer bottle 130 are connected, the baffle 124 moves freely at the notch 130-7, and the rib 130-5 and the limiting rib 125 do not contact each other. When the rotating member 120 and the outer bottle 130 are separated or completely locked, the limiting rib 125 will abut and pass over the rib 130-5, and the baffle 124 and the limiting rib 125 are relatively located between the notch 130-7 and the rib 130-5, thereby limiting the further movement of the rotating member 120.

[0040] The inner wall of the inner vertical wall 123 is provided with a hanging rib 122 below the guide groove 121, and the guide cylinder 211 and the hanging rib 122 can abut against each other. After the rotating member 120 and the outer bottle are unlocked, the guide cylinder 211 will be stuck above the hanging rib 122 to prevent it from falling directly.

[0041] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
