Description

Air-suck-back prevention watering can

Technical Field

The utility model relates to a watering can.

Background

At present, the sprinkling can commonly seen on the market comprises an air return nozzle with a suction pipe and a can body, wherein the can body is single-layer, and the working principle of the sprinkling can is as follows: the nozzle is pressed to press the air in the kettle body to act on the surface of the spray liquid, so that the spray liquid is sprayed out for use after passing through the suction pipe and the air pump in the nozzle; when the nozzle is released, the outside air is sucked back into the kettle by the air pump to prepare for spraying the liquid again by pressing the nozzle next time. It can be seen from the above that the air in the kettle body is pressed to act on the surface of the liquid spray to spray the liquid spray, so that the air is always present in the bottle, and the spraying kettle with the structure is not suitable for containing liquid with longer quality guarantee period or sensitive to air.

To this end, the applicant has developed a watering can that prevents air from being sucked back.

Disclosure of Invention

An object of the utility model is to overcome prior art's not enough, provide a rational in infrastructure, be fit for the splendid attire to the air resorption watering can of the more sensitive liquid of air, it helps guaranteeing the product quality of splendid attire hydrojet.

In order to solve the technical problem, the utility model adopts the following technical scheme:

an air suck-back prevention watering can comprises a pistol pump with a suction pipe and a can body, wherein the can body is of a double-layer type and comprises a hard outer can body on the outer layer and a soft bag on the inner layer; the kettle mouth of the outer kettle body is provided with an outer thread which is in threaded connection with a kettle cover on the pistol pump; the bag opening of the soft bag is fixedly connected with the inner wall of the kettle opening of the outer kettle body; a plurality of air inlets which are communicated with the inside and the outside of the outer kettle body are arranged on the outer kettle body; the suction tube of the pistol pump is inserted into the flexible bag.

In the improved scheme of the air suck-back prevention watering can, the air inlet is arranged at the bottom of the outer can body.

Compared with the prior art, the beneficial effects of the utility model are that: owing to adopt the pistol pump of evacuation, and the double-deck formula kettle body of constituteing by the outer kettle body that takes the air inlet hole and soft bag, like this, the limit utilizes the outside air to act on the soft bag surface to spout liquid smoothly to soft bag evacuation on the one hand, in the soft bag that splendid attire hydrojet can not the resorption to the outside air of on the other hand, in being the microorganism in the air, material such as corpuscle can not enter into the kettle along with the air, thereby greatly reduced the influence of the material in the air to the hydrojet that the watering can splendid attire, the shelf life of the hydrojet of having guaranteed the splendid attire is longer, help guaranteeing the product quality of the splendid attire hydrojet promptly, consequently the utility model discloses a rational in infrastructure, be fit for the splendid attire liquid sensitive to the.

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

[ detailed description ] embodiments

The utility model relates to a prevent air resorption watering can, as shown in fig. 1 to 5, including pistol pump 2 and the kettle body 3 of taking straw 1, wherein pistol pump 2 adopts the vacuum pump commonly used at present stage, therefore its structure no longer details here, the difference is:

the kettle body 3 is of a double-layer type and comprises a hard outer kettle body 31 at the outer layer and a soft bag 32 at the inner layer; the kettle mouth of the outer kettle body 31 is provided with outer threads which are in threaded connection with the kettle cover 4 on the pistol pump 2; the mouth of the soft bag 32 is fixedly connected with the inner wall of the pot mouth of the outer pot body 31; the outer kettle body 31 is provided with a plurality of air inlet holes 311 which are communicated with the inside and the outside of the outer kettle body; the suction tube 1 of the pistol pump 2 is inserted into the soft bag 32.

In this embodiment, the soft bag 32 is adapted to the outer pot body in shape, and the bag body is not fixedly connected to the inner wall of the outer pot body 31, so that the air introduced into the outer pot body 31 acts on the periphery of the bag body.

When the utility model is used, the spray liquid is injected into the soft bag 32, and then the suction pipe on the pistol pump 2 is inserted into the kettle body and then the kettle cover 4 is screwed up to the kettle opening of the outer kettle body 31. When the spray can is used for spraying the spray liquid for the first time, the pistol pump is pressed repeatedly, and the vacuum pump is used, so that when the pistol pump is released after pressing each time, outside air cannot be sucked back into the can, and as the air in the suction pipe is gradually pumped out, part of the spray liquid can be sucked into the suction pipe under negative pressure, and the spray liquid can be sprayed out after the pistol pump is pressed for multiple times; meanwhile, air entering the outer kettle body 31 from the air inlet 311 acts on the outside of the soft bag, so that the volume of the negative pressure soft bag is reduced under the air pressure, and the spraying of the liquid is facilitated.

From the above, the utility model discloses an adopt the pistol pump 2 of evacuation, and the double-deck formula kettle body of constituteing by soft bag 32 and the outer kettle body 31 of taking gas inlet 311, thus, on the one hand, the limit utilizes the outside air to act on the soft bag 32 surface to soft bag 32 evacuation limit to spout liquid smoothly, on the other hand external air can not the resorption in the soft bag of splendid attire hydrojet, in the microorganism in the air, material such as corpuscle can not enter into the kettle along with the air, thereby greatly reduced the influence of material in the air to the hydrojet that the hydrojet splendid attire was splendid attire, ensured that the shelf life of the hydrojet of splendid attire is longer, help guaranteeing the product quality of splendid attire hydrojet promptly, consequently the utility model discloses a rational in infrastructure, be fit for the splendid attire liquid material more sensitive to the air.

The air inlet holes 311 may be provided on the sidewall or the bottom of the outer pot body. In this embodiment, the air inlet 311 is disposed at the bottom of the outer can body 31, so that the appearance of the watering can is not affected, and the printing or labeling on the side wall of the outer can body is not affected.

The soft bag can be formed (such as blow molding) firstly, then is arranged in the outer kettle body, and the bag opening of the soft bag and the kettle opening of the outer kettle body are welded together by ultrasonic waves and the like; of course, after the soft bag is formed (such as blow molding) in the outer kettle body by using a more advanced technology, the bag opening of the soft bag and the kettle opening of the outer kettle body can be fixedly connected together by using ultrasonic welding and other modes.

Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims. Therefore, the detailed description of the embodiments of the present disclosure is to be construed as merely illustrative, and not limitative of the present disclosure, but rather to limit the scope thereof by the appended claims.
