Description

Technical Field

[0001] The utility model relates to the technical field of watering cans, in particular to a contact-free watering can. Background Art

[0002] As the name suggests, a watering can is a pot-shaped tool that can spray liquids (such as water, detergent, conditioner, etc.). Its design allows the liquid to be evenly and precisely applied to the target area in the form of a mist, a thin stream, or a water column. In gardening, watering cans are commonly used for watering plants, fertilizing, and pest control; in household cleaning, they can be used to spray detergent on various surfaces; and in hair care, watering cans are convenient for evenly spraying water or conditioner onto hair.

[0003] Existing spray bottles usually require users to inject liquid medicine into the spray bottle. During this process, the user must first inject the liquid medicine into the spray bottle, then add water to the spray bottle, and then shake the spray bottle to mix the two evenly. Since many liquid medicines are usually corrosive and have a strong irritating odor, this usage method can easily cause the liquid medicine to splash out of the spray bottle, contact the user's skin and clothes and corrode them, thereby causing injury to the user, which is not user-friendly.

[0004] Therefore, the present application provides a contact-free spray bottle to overcome the defects of the prior art. Utility Model Content

[0005] The utility model aims to solve the problem that when the existing spray bottle is used, the liquid medicine is easily splashed out of the spray bottle, contacts the user's skin and clothes and corrodes them, thereby causing injuries to the user.

[0006] The technical solution of the present utility model provides the following technical solution: a contact-free spray pot, comprising a spray pot, wherein a connecting hole 1 and a connecting hole 2 are provided on the top of the spray pot, a connecting pipe 1 is fixed to the top of the spray pot, the connecting pipe 1 is connected to the connecting hole 1, an external thread 1 is fixed on the outer wall of the connecting pipe 1, the connecting pipe 1 is threadedly connected to the medicine storage pipe through the external thread 1, a connecting pipe 2 is also fixed to the top of the spray pot, the connecting pipe 2 is connected to the connecting hole 2, an external thread 2 is fixed on the outer wall of the connecting pipe 2, the connecting pipe 2 is threadedly connected to the spray head (not shown in the figure) through the external thread 2.

[0007] The medicine storage tube includes a connecting plate 1, a connecting plate 2 is fixed to the top of the inner wall of the connecting plate 1, a pressing portion is fixed to the bottom of the inner wall of the connecting plate 2, the top of the connecting plate 1 is flush with the top of the connecting plate 2, the bottom of the connecting plate 2 is flush with the bottom of the pressing portion, the top height of the pressing portion is lower than the top heights of the connecting plate 1 and the connecting plate 2, an internal thread is fixed on the inner wall of the connecting plate 1, and the connecting plate 1 is threadedly connected to the connecting tube 1 through an internal thread and an external thread.

[0008] The axial cross-section of the connecting plate 1 is two oppositely arranged arcs, and the radial cross-section is a hollow circle. The wall thickness of the pressing part is 1 mm. The pressing part is made of PE material, consisting of high-density polyethylene (HDPE) and low-density polyethylene (LDPE), of which high-density polyethylene (HDPE) accounts for 80% and low-density polyethylene (LDPE) accounts for 20%.

[0009] A connecting tube three is fixed on the bottom wall of the connecting plate two and the pressing part, a liquid medicine composite film is glued to the bottom wall of the connecting tube three, a connecting tube four is fixedly connected to the bottom wall of the pressing part, a plurality of connecting blocks are fixed on the bottom wall of the connecting tube four, the connecting tube three is set on the outside of the connecting tube four, the connecting tube three, the liquid medicine composite film, the connecting plate two and the pressing part form a closed space, the connecting tube four and the connecting block are in the closed space, the bottom wall of the connecting block is higher than the top wall of the liquid medicine composite membrane, and the distance between the bottom wall of the connecting block and the top wall of the liquid medicine composite membrane is 0.5 mm.

[0010] The liquid medicine composite membrane includes a closing film 1, the top wall of the closing film 1 is glued to the bottom wall of the connecting tube 3, the bottom wall of the closing film 1 is glued to the closing film 2, and the bottom wall of the closing film 2 is glued to the closing film 3. The closing film 1 is made of PE material, the closing film 2 is made of aluminum foil, and the closing film 3 is made of PET material.

[0011] The beneficial effects of the contact-free spray bottle provided by the utility model are:

[0012] The utility model provides a closed space composed of the connecting pipe three, the liquid medicine composite membrane, the connecting plate two and the pressing part, so that the liquid medicine is sealed in the closed space and will not easily flow out. By arranging the connecting pipe four and the connecting block in the closed space, due to the special material of the pressing part, when the user presses the pressing part hard, the pressing part can be moved downward, thereby driving the connecting pipe four and the connecting block to move downward, penetrating the liquid medicine composite membrane, and allowing the liquid medicine in the closed space to flow into the spray bottle. During the whole process, the user does not need to directly contact the liquid medicine, and the liquid medicine will not splash on the user. The utility model is safe, reliable, convenient and fast to use, and very user-friendly.

[0013] By setting the top height of the pressing part to be lower than the top height of connecting plate 1 and connecting plate 2, since connecting plate 1 and connecting plate 2 are higher than the height of the pressing part, heavy objects can be prevented from directly pressing on the pressing part during transportation, and connecting tube 4 and connecting block can be prevented from penetrating the liquid medicine composite membrane when not in use, thereby avoiding damage to the goods during transportation.
