Description

Intelligent watering can

Technical Field

The utility model relates to an articles for daily use technical field, concretely relates to intelligence watering can.

Background

In daily household life, people often need to clean some high-value and precious small-particle articles, such as diamonds of jewel ornaments, rings, earrings, earnails, earpendants, chest pendants, contact lenses of corneal contact lenses, cosmetic pupils, hard corneal contact lenses and the like.

For granular articles of the gemstone category, one common cleaning method is to use a manual method: pouring a proper cleaning solution into a vessel, immersing the ornament in the cleaning solution, brushing the ornament with a soft-bristle toothbrush, then washing the ornament with clean water, wiping the ornament with soft lint-free cloth, and wearing or storing for use. The other cleaning method is to use an ultrasonic automatic cleaner for cleaning, soak the ornaments in cleaning solution, separate the dirt accumulated at various positions of the ornaments by using vibration and impact generated by cavitation effect of ultrasonic high-frequency oscillation, then wash the ornaments with clean water, wear the ornaments after drying treatment or store the ornaments for storage. Finally, the cleaning bin of the automatic cleaner is washed by clean water, and the automatic cleaner is dried in the air or wiped to be convenient for the next use.

For corneal contact lens articles, a common cleaning method is a manual rubbing cleaning method, which includes placing a lens in the center of the left hand after cleaning both hands, then dripping a few drops of a care solution, rubbing and cleaning the lens with the fingers of the right hand, then washing the lens with clean water, and finally wearing the lens or storing the lens, wherein the lens is usually required to be stored in the care solution in actual operation. The other cleaning method is to use an automatic corneal contact lens cleaner for cleaning, inject a care solution into a cleaning chamber, immerse the lens in the care solution, automatically complete the cleaning work by a machine, then wash the lens with clean water, wear the lens or store and store the lens. Finally, clean water is needed to wash the cleaning bin of the automatic cleaner, and the automatic cleaner is dried in the air or wiped to be convenient for next use.

The two types of article cleaning processes involve an important link, namely, the washing of the articles, namely, the process of rinsing the articles with clean water and washing the cleaning solution on the surfaces of the articles.

The flushing operation is preferably carried out on the table top together with the above-mentioned washing operation, using the container placed on the table top as a sink, instead of directly using the sink in the kitchen or toilet. Because if a sink rinse of a kitchen or toilet is used, there are several obvious problems: firstly, articles are easy to slide off and lose, enter a sewer and are washed away with water flow, and great loss is brought to families; secondly, in order to prevent accidents, a net bag or a filter screen needs to be prepared in advance to contain articles and a water outlet needs to be blocked, and the actual operation is troublesome; thirdly, articles may slip off from the hands during the process of changing from the table top to the sink, so that the articles are broken or scratched; fourthly, the water quality provided by tap water or the water purifier can not meet the requirements of washing the articles; fifthly, the flow and the impulsive force of a tap of a kitchen or a water purifier are difficult to adjust to proper values; the use is placed in the container of desktop as the washing mode of basin, washs and is washed the operation and need not change the place, and article take off when having avoided moreover washing directly get into the sewer, have two other advantages in addition: firstly, the table top can provide better operating environment, such as better lighting condition, can be used for being laid on the table top by towels to prevent objects from falling off and scratching, and can be easily found in case of falling off the table top. Secondly, the container can be filled with clean water with different water qualities as a rinsing medium according to the requirement, such as common cold boiled water, commercially available bottled water, or filtered direct drinking water, or the cold boiled water after the direct drinking water is boiled, so that the requirement of rinsing or flushing the articles on the water quality can be met.

The following three ways of rinsing a jewel or contact lens type particle object using a container placed on a table as a water tank are available:

the first mode is as follows: the jewel ornament particle articles are clamped by clips or fingers and rinsed (placed in water and swung) in a container filled with clean water for a period of time so as to wash away residual cleaning agent on the surfaces of the articles. The disadvantage of this method is obvious, and it needs many water changing and rinsing operations to remove the residual detergent on the surface of the article.

The second mode is as follows: after clean water is filled in a common mineral water bottle or sauce squeezing bottle, one hand holds the jewel ornament particles (or clamps are used for clamping) and the other hand holds the bottle body to enable the bottle mouth to face downwards, the bottle body is inclined or squeezed to form water flow to be poured on an object to be washed, and meanwhile, an open container is used as a water tank to be placed below the object to be washed to collect waste liquid. In this way, the flowing clean water is used for washing the article, the residual cleaning agent on the surface of the article can be quickly removed, and the flow can be adjusted according to the requirement (the size and the weight of the article to be washed), but the operation of the method is inconvenient: only one hand is actually washing the items during rinsing, as the other hand is holding the bottle to provide water flow. In this manner, both hands cannot be used simultaneously to wash the articles, and manual squeezing or pouring is difficult to provide a continuous, steady stream of water.

The third mode is as follows: the flushing mode of soft particle articles such as contact lenses of corneal contact lenses, cosmetic pupils and hard corneal contact lenses is similar to that of the second mode, but the difference is that a cleaning person needs to use both hands to contact the articles simultaneously to perform flushing operation, and the requirements on water quality and water flow are higher. The common ways are: a common sauce squeezing bottle or mineral water bottle (a small hole is arranged on a bottle cover) is filled with clean water, an open container is used as a water tank, a cleaning worker places the left hand above the water tank with the palm upward, places the lens at the palm of the left hand, and performs scrubbing operation by using the finger abdomen of one finger of the right hand. At this time, an assistant is required to hold the water bottle with the bottle mouth facing downward, to tilt or to squeeze the bottle body to provide water flow. This method requires precise cooperation and cooperative operation of two persons to complete the cleaning task. Because such articles are characterized by transparency, light weight, flexibility, and small flake-like particles, the impact and flow of the water flow during rinsing must be appropriate, the water flow is stable and directed at the lens; moreover, because the quality of water required for flushing such articles is high, the on-off of water flow is proper so as to avoid unnecessary waste of water resources, which requires accurate and cooperative operation of cleaning personnel and assisting personnel. This approach wastes the attendant time that would otherwise be spent working or resting, and also has the problem that the coordination is not easily mastered. Both parties can complete the cleaning work cooperatively after running-in and training for a period of time.

The infrared induction faucet with the automatic induction control water flow switch is very common in public toilets, water can be supplied and received by hands and can be stopped in an induction area, the hands do not need to contact the faucet, the water flow can be automatically turned on and off through the inductor, the use is convenient, and water resources can be effectively saved. However, conventional infrared sensing faucets are too large and non-adjustable in flow and also suffer from the aforementioned problems of flushing particulate items using kitchen and toilet sinks. In addition, although the household water purifier faucet can provide water with higher cleanliness, the common infrared induction faucet in the market is generally suitable for being connected with a tap water pipeline, is difficult to adapt to the common water purifier pipeline in the market, and can be connected to the water purifier pipeline only by being modified; in addition, the quality of the outlet water filtered by the water purifier can not necessarily meet the requirements of the sanitation and cleanliness of the cornea contact lens articles.

The common auto-induction soap dispenser on the market has the function of auto-induction spraying of the hand sanitizer: when a hand stretches to the induction zone, a ball of water is pumped out for bathing, but continuous water flow cannot be output, the functions of continuous water outlet when the hand stretches to the induction zone and immediate water cut-off when the hand is retracted cannot be realized, and in addition, the automatic induction soap dispenser usually uses a special water pump for the soap dispenser and is provided with a foam maker, and water flow cannot be output.
