DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] refer to Figures 1 to 6 , an inner bottle structure, comprising a cylinder 1 and a connecting column 2, wherein the cylinder 1 is movably connected to an external bottle body, the cylinder 1 is provided with a liquid storage bin 11 with an open upper surface and a channel 12 for connecting the bottle body with the outside, the connecting column 2 is connected to the channel 12, and the outer side surface of the connecting column 2 is completely in contact with the inner wall of the channel 12;

[0026] The connecting column 2 is provided with a liquid outlet cavity 21 for connecting the bottle body with the outside, and the liquid outlet cavity 21 is arranged vertically;

[0027] The input end of the connecting column 2 contacts the bottom of the external bottle body, and the input end of the connecting column 2 is provided with at least one notch 241 for materials to enter the liquid outlet cavity 21;

[0028] The output end of the connecting column 2 is provided with a recess 221 matching with the external pump body, and the liquid outlet cavity 21 is communicated with the recess 221 .

[0029] Under this design, after installation, the outer side surface of the connecting column 2 is completely in contact with the inner wall of the channel 12, that is, the outer diameter of the connecting column 2 and the inner diameter of the channel 12 are matched, which makes it easier to install the connecting column 2, and a recess 221 matching the external pump body is provided at the output end of the connecting column 2, so as to facilitate the connection of the external pump body with the connecting column 2, and the cooperation between the recess 221 and the pump body realizes a sealed environment around the pump body; after the installation inside the cylinder 1 is completed, the cylinder 1 is installed in the external bottle body, at which time the input end of the connecting column 2 just contacts with the bottom of the external bottle body, and at least one notch 241 is provided at the input end of the connecting column 2 for materials to enter the liquid outlet cavity 21, so as to ensure that the connecting column 2 can absorb the materials at the bottom of the bottle body.

[0030] Under the two conditions that the outer side surface of the connecting column 2 is completely in contact with the inner wall of the channel 12 and the input end of the connecting column 2 is in contact with the bottom of the external bottle body, the connecting column 2 and the liquid outlet cavity 21 in the connecting column 2 are in a vertical state, which is the shortest stroke for material output, making it easier to pump out the material.

[0031] Preferably, a support portion 121 is provided at the bottom of the channel 12 , and when the connecting column 2 is connected to the channel 12 , the bottom of the connecting column 2 contacts the support portion 121 , and the output end of the connecting column 2 passes through the support portion 121 and contacts the bottom of the external bottle body.

[0032] In actual use, by setting a support part 121 at the bottom of the channel 12, the connecting column 2 can be supported and the sealing between the connecting column 2 and the inner wall of the channel 12 can be ensured to prevent materials from entering between the connecting column 2 and the inner wall of the channel 12.

[0033] Preferably, the connecting column 2 includes a first connecting part 22 and a second connecting part 24 matching the inner wall of the channel 12, and a connecting tube 23 connected between the first connecting part 22 and the second connecting part 24, the liquid outlet cavity 21 completely penetrates the first connecting part 22, the connecting tube 23, and the second connecting part 24, the recess 221 is located on the first connecting part 22, and the input end of the connecting column 2 is located on the second connecting part 24.

[0034] Specifically, when installing the connecting column 2, the second connecting part 24 first enters into the channel 12, so the second connecting part 24 can play a role of pre-positioning, and then as the second connecting part 24 continues to approach the supporting part 121, the first connecting part 22 will also enter into the channel 12, and the first connecting part 22 and the second connecting part 24 are completely in contact with the inner wall of the channel 12, thereby ensuring the sealing between the connecting column 2 and the inner wall of the channel 12.

[0035] As a further optimization of this embodiment, it also includes a connecting plate 231, and a plurality of the connecting plates 231 are arranged in a circular array around the outer side surface of the connecting tube 23. When the connecting column 2 is connected to the channel 12, the first connecting part 22, the second connecting part 24, and the connecting plate 231 are completely in contact with the inner wall of the channel 12.

[0036] We found that during the installation process, the second connecting part 24 cannot play a role in complete pre-positioning. When the first connecting part 22 reaches the channel 12, manual positioning is still required. Therefore, the connecting tube 23 can be thickened so that the connecting tube 23 can also fit with the inner wall of the channel 12, but this will undoubtedly increase the overall weight. Therefore, we arrange connecting plates 231 in a circular array on the outer side of the connecting tube 23. This not only enables the connecting tube 23 to fit with the inner wall of the channel 12 and ensure the stability of the connecting tube 23, but also increases weight less than the overall thickening method.

[0037] In this embodiment, the first connection part 22, the second connection part 24, the connection pipe 23, and the connection plate 231 are an integrally formed structure. Preferably, the first connection part 22, the second connection part 24, the connection pipe 23, and the connection plate 231 are integrally injection molded, which reduces the number of parts and assembly procedures, thereby simplifying the manufacturing process, and can reduce the risk of leakage at the joints, ensuring the sealing and safety of the connection pipe 23.

[0038] More preferably, the input end of the connecting column 2 is provided with two notches 241 , and the two notches 241 are symmetrically arranged.

[0039] The present embodiment uses two notches 241 only to meet the requirement of material pumping and facilitate processing. Of course, three, four or five notches may also be selected.

[0040] In this embodiment, a support plate 13 is provided on the top of the cylinder 1 along the outer edge of the top. When the cylinder 1 is movably connected in the bottle body of the external device, the support plate 13 contacts the top of the bottle body of the external device so that the bottom of the cylinder 1 is suspended in the air. An exhaust port 15 is also provided on the side of the cylinder 1.

[0041] It can be understood that after adding the support plate 13, as long as the cylinder 1 is placed in the external bottle body, the cylinder 1 can be stuck, and the bottom of the cylinder 1 is suspended in the air, which is not only convenient for installation, but also convenient for disassembly. The cylinder 1 can be taken out by simply holding the support plate 13 and lifting the cylinder 1. The exhaust port 15 is for facilitating the entry of air during installation and removal.

[0042] As a further optimization of this embodiment, a plurality of limit plates 14 are further provided on the outer side surface of the cylinder 1 , and the plurality of limit plates 14 are arranged in an array along the outer side surface of the cylinder 1 .

[0043] In actual use, if the outer side surface of the cylinder 1 just matches the bottle mouth of the external bottle body, a piston effect will be formed during the installation or removal process, causing material splashing. If the cylinder 1 is smaller than the bottle mouth of the external bottle body, the cylinder 1 will shake. Therefore, we set a plurality of limit plates 14 on the outer side surface of the cylinder 1 to reduce the contact area between the outer side surface of the cylinder 1 and the bottle mouth of the external bottle body, thereby avoiding the piston effect and preventing the cylinder 1 from shaking.

[0044] Preferably, in the horizontal section of the cylinder 1, the liquid storage bin 11 is crescent-shaped, the channel 12 is circular, the missing portion of the crescent-shaped portion matches the circle, and the area of ​​the crescent-shaped portion is 3 to 4 times greater than the area of ​​the circle.

[0045] Because the channel 12 is only used to connect the material inside the external bottle body with the outside, the smaller the channel 12 is, the better while ensuring smooth discharge; and the liquid storage bin 11 is used to store the second material, so the larger the liquid storage bin 11 is, the better without affecting the capacity of the external bottle body.

[0046] Example 2

[0047] refer to Figure 7 A pump bottle comprises a bottle body 3, an inner cover 4, a first pump body 5, a second pump body 6, a pressure cover 7, an outer cover 8 and the inner bottle structure as described above, wherein the cylinder body 1 is movably connected in the bottle body 3, the inner cover 4 is connected to the top of the bottle body 3, the first pump body 5 and the second pump body 6 are both connected to the inner cover 4, and the lower ends of the first pump body 5 and the second pump body 6 are respectively located in the channel 12 and the liquid storage bin 11, and the lower end of the second pump body 6 is provided with a pipeline 61;

[0048] The pressure cap 7 is connected to the upper ends of the first pump body 5 and the second pump body 6. The pressure cap 7 is provided with a first input chamber 71 and a second input chamber 72 respectively connected to the first pump body 5 and the second pump body 6, and at least one output chamber 73 connected to the first input chamber 71 and the second input chamber 72. The outer cover 8 is connected to the inner cover 4.

[0049] When in use, by unscrewing the outer cover 8 and pressing the pressure cover 7, the pressure cover 7 squeezes the first pump body 5 and the second pump body 6 at the same time, outputs the first material in the bottle through the first pump body 5, and outputs the second material in the liquid storage tank 11 through the second pump body 6, and the first material and the second material enter the first input cavity 71 and the second input cavity 72 respectively. By arranging at least one output cavity 73 on the pressure cover 7, the first material and the second material can be discharged separately or mixed.

[0050] Moreover, the pump bottle adopts a connecting column 2 that is completely in contact with the inner wall of the channel 12. The output end of the connecting column 2 is provided with a recess 221 that matches the external pump body, which makes installation more convenient. A notch 241 is provided at the input end of the connecting column 2 to cooperate with the input end of the connecting column 2 to contact the bottom of the external bottle body, thereby ensuring that the material at the bottom can be sucked up while making the material's travel through the connecting column 2 as short as possible, making it easier to pump out the material.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
