The same or similar reference numerals in the drawings represent the same or similar parts.

[0029] As Figs. 1 to 4 shown, the auxiliary tool 10 for inter-bucket transfer of liquid chemicals provided by some embodiments of the present application includes an adapter 100 and a hose 200. The adapter 100 has a cavity 101 extending through its own axial direction. The adapter 100 further includes a first segment 110 and a second segment 120 connected axially, the inner wall of the first segment 110 is provided with threads 102, and the second segment 120 is connected with the hose 200, and the cavity 101 is in communication with the lumen of the hose 200.

[0030] The auxiliary tool 10 is applied to the process of transferring liquid chemicals in a stacking barrel to a daily-use barrel. Those skilled in the art know that the stacking barrel comprises a first barrel body and a cover, the first barrel body is provided with a first barrel opening, the outer wall of the first barrel opening is provided with a thread, and the cover is threadedly connected at the first barrel opening; the daily-use barrel comprises a second barrel body, and the second barrel body is provided with a second barrel opening. "Transferring liquid chemicals in a stacking barrel to a daily-use barrel" refers to transferring liquid chemicals loaded in the first barrel body to the second barrel body.

[0031] The process of applying the auxiliary device 10 provided by the embodiments of the present application to transfer the liquid chemicals in the stacking barrel to the daily-use barrel is as follows:

[0032] First, the cover is removed from the first barrel body.

[0033] Next, the adapter 100 of the auxiliary tool 10 is connected to the first barrel opening through the thread 102 of the first segment 110. It should be understood that the thread 102 matches the thread on the outer wall of the first barrel opening, so that they can be connected together.

[0034] Next, the end of the hose 200 away from the adapter 100 is inserted into the second barrel body from the second barrel opening.

[0035] Next, the operator lifts the first barrel body and tilts it so that the liquid chemicals in the first barrel body enter the second barrel body along the cavity 101 of the adapter 100 and the lumen of the hose 200. In this way, the liquid chemicals will not splash during the transfer process.

[0036] Optionally, the outer surface of the first segment 110 is provided with anti-slip patterns 111. In this way, it is convenient to operate when connecting the adapter 100 to the barrel opening.

[0037] In some embodiments, the adapter 100 and the hose 200 are detachably connected. In this way, when the auxiliary tool 10 is not in use, the hose 200 and the adapter 100 can be detached and stored separately to simplify storage difficulty and improve the cleanliness of the workplace.

[0038] Further, preferably, the auxiliary tool 10 further comprises a fastener 300, which can be connected to the hose 200 and apply a force to the hose 200 and the adapter 100 in the connected state to prevent the hose 200 from separating from the adapter 100.

[0039] In an optional example, when the second section 120 is at least partially threaded in the lumen of the hose 200 to achieve the connection of the hose 200 and the adapter 100, the fastener 300 can be arranged on the portion of the hose 200 that is sleeved on the outer side of the second section 120, and exerts a pressing force along the radial direction of the second section 120 on the hose 200 and the second section 120, so that the hose 200 and the adapter 100 are not separated.

[0040] Preferably, the fastener 300 is detachably connected to the hose 200. In this way, the fastener 300 and the hose 200 can be separately stored. In an exemplary example, the fastener 300 includes a handle grommet, so that the fastener 300 can be reused. Alternatively, the fastener 300 can also be a cable tie, so that the fastener 300 is a non-reusable consumable.

[0041] In practice, the first bucket opening has a larger diameter, and the inner diameter of the hose 200 can be smaller. In view of this, the outer diameter of the second section 120 can be smaller than the outer diameter of the first section 110, so that the first section 110 can be threadedly connected to the bucket opening, and the second section 120 can be at least partially threaded in the lumen of the hose 200.

[0042] Optionally, the second section 120 includes a first sub-section 121 and a second sub-section 122, the outer diameter of the second sub-section 122 is smaller than that of the first sub-section 121, and the second sub-section 122 is used to be at least partially threaded in the lumen of the hose 200.

[0043] Optionally, the hose 200 can include a first polymer layer 210, a metal support layer 220 and a second polymer layer 230 arranged in sequence from inside to outside. The metal support layer 220 includes a three-dimensional spiral structure formed of metal and wound on the first polymer layer 210. The first polymer layer 210 and the second polymer layer 230 are both transparent layers. In this way, during the transfer of liquid chemicals to the household bucket, the operator can observe the state of the liquid chemicals in the lumen of the hose 200, such as color, presence of foreign matter, etc., so as to timely find quality problems of the liquid chemicals.

[0044] Although the foregoing describes the detachable connection of the hose 200 and the adapter 100 as an example, in practice, the hose 200 can also be non-detachably connected to the adapter 100.

[0045] Although the utility model discloses as above, but is not limited to this. The person skilled in the art can make various changes and variations to the utility model without departing from the spirit and scope of the utility model. In this way, if these modifications and variations of the utility model are within the scope of the claims of the utility model and its equivalent technologies, then the utility model also intends to include these changes and variations.
