Description

Watering pot

Background

From document US2013/0249689 a1 a watering pot with a time function for reminding a user to irrigate his plants is already known. DE 202013004328 discloses a watering can with an electric pump, wherein the watering can has an irrigation function and a spraying function. DE 102014001757 a1 describes a watering can attachment which is designed in such a way that as much oxygen as possible is supplied to the irrigation water during pouring.

Disclosure of Invention

The invention relates to a watering pot for watering plants, comprising in particular a container, a handle and a spout or a watering tube. It is proposed that the watering can have means for generating fine bubbles, micro-bubbles and/or nano-bubbles. For the definition of fine (Fein) bubbles, Micro (Micro) bubbles and/or Nano (Nano) bubbles, reference is made to page 1, lines 10 to 22 of WO2014/184585 a2, which is therefore also an integral part of the present application. Thus, especially smaller bubbles such as Femto-bubbles or Zepto-bubbles also fall under fine bubbles, micro-and/or nano-bubbles and mixtures thereof. Furthermore, reference is made to the entire document WO2014/184585 a2 as regards the general understanding and Background of fine bubbles, microbubbles and/or nanobubbles and their generation and their nature, however especially the section entitled "Background" on page 1, line 9 to page 5, line 24 and the other documents cited in this section (page 4, line 21 to page 5, line 24).

By: the watering can according to the invention has or comprises means for generating fine bubbles, microbubbles and/or nanobubbles, so that bubbles can be generated near the point of use (for watering or during watering). The following steps are cancelled: the use of a separate generator, complex infusions of liquids rich in fine bubbles, microbubbles and/or nanobubbles, etc. It is possible to provide directly, user-friendly, diversified properties for use, in particular for assisting the germination, growth and yield of plants. For this purpose, the device or generator for generating fine bubbles, microbubbles and/or nanobubbles can be located in, mounted on or at least connected to a container filled with a liquid, in particular water. Advantageously, the watering can be activated or switched on to generate gas bubbles in such a way that they can be poured out with the watering and/or can be stored or stored, in particular, in a further intermediate container integrated in the watering can or connected to the watering can.

Furthermore, it is proposed that the watering pot has an energy store to supply energy to the device or generator for generating fine bubbles, microbubbles and/or nanobubbles. The energy store can be, for example, a battery or a dry cell battery. Fuel cells with air reservoirs, if necessary, can also be envisaged. The battery can be a hand-held power tool battery, which can be used, for example, in a battery interface that is standardized in particular at least in a manufacturer-specific manner. The dry cell or battery interface can be external, for example on a side wall of the watering can, in particular opposite the watering can, or arranged similarly.

Alternatively or additionally to the battery and dry cell, the watering can also be connected to or equipped with an interface, contact base and/or docking station, at least for supplying energy to the device for generating fine bubbles, microbubbles and/or nanobubbles. The device or generator and the accumulator can be supplied with energy, in particular with current or charging current, via the interface, inductively, electrically, by means of, in particular, an electrical contact base or by means of a plug-in connection. The advantages generally known from boilers with contact bases can therefore also be applied to the watering can according to the invention. Thereby improving user and operator friendliness and safety.

It is also proposed that the watering can be equipped with an interface, a contact base and/or a docking station at least for supplying data, input parameters or regulating parameters to the device for generating fine bubbles, microbubbles and/or nanobubbles or for reading data. Thus, networking functionality, in particular "internet of things" functionality, can be provided. Furthermore, the possibility of inputting or adjusting and the possibility of outputting feedback information, etc. is thereby provided.

Furthermore, a watering can is proposed, which has means for determining and/or monitoring:

a. bubble generation time and/or

b. Amount of bubble generation and/or

c. Bubble size and/or

d. The liquid temperature or the water temperature.

Such means can be, for example, an operating panel, an LCD display, an external device such as a smartphone or a computer, etc. The watering can also have a controller or a regulator, one or more sensors or measuring or sensing devices as a device. Suitable bubble generation duration, bubble generation amount, bubble size, or other edge or frame conditions may thereby be achieved. The pouring device or the pouring device can be adapted to the particular application (fertilization required differently, activation, deactivation of the water, etc.); the pouring device or pouring device can be activated in advance, so that it is precisely switched on in time; the pouring device or pouring device can also be provided repeatedly as a timing function, etc. Certain bubble sizes and/or bubble amounts can be maintained within tolerances. It is also possible to match the temperature of the liquid to the needs of the plant. For this purpose, the watering can also have a heating or cooling device. The heating or cooling device can also be isolated or have a plurality of separate and independent volumes in which different liquid properties, such as bubble concentration, water temperature, etc., are present.

Furthermore, a watering pot is proposed, which has an interface for inputting control parameters and/or an interface for outputting and/or visualizing "production parameters" and/or signals. In addition to a man-machine interface, this can also be understood as a data transmission interface or a machine-machine interface. For example, to implement "internet of things" functionality and to provide a "smart" appliance that can itself actively or passively communicate with other devices, plants, plant chips or plant tags, etc.

Furthermore, a watering pot with a device for admixing fertilizers and/or herbicides, insecticides and/or fungicides is proposed, in particular from one or more reservoirs, in particular cartridges or storage rods, for fertilizers, herbicides, insecticides or fungicides. Such a reservoir or storage bar can be flushed from all around during pouring. The reservoir or stick can contain nutrients that promote or modify plant growth. Hereby, watering and fertilizing and/or treatment of the plants can be combined in a practical manner. In particular, the amount of the fertilizer or the treating agent can be automatically metered, and the ratio of water to the fertilizer or the treating agent can be ideally matched; the characteristics of the respective plants can be taken into account.

Furthermore, a watering can with a device, in particular a generator, for generating a plasma-activated liquid, in particular plasma-activated water, is proposed. Thereby also promoting the growth, health, beauty or yield of the plant.

The invention further relates to a device for generating fine bubbles, microbubbles and/or nanobubbles, comprising a device for conveying a bubble-laden liquid through a microbubble generator, in particular a pump, and a nozzle downstream of the microbubble generator. It is proposed that the rear nozzle is arranged with a collision plate. Different micro-bubble generators are known from page 9, lines 12 to 24 of WO2014/184585 a2, such as venturi bubble generators, swirl bubble generators, mixing bubble generators, cavitation bubble generators, pressurized dissolving bubble generators, which are also described in the description of the figures 8a-8v and the related figures on pages 16 to 20. By providing the collision plate after the nozzle, the bubbles can be further pulverized and reduced in a simple and cost-effective manner. Such a device can be manufactured cost-effectively.

Furthermore, watering pots, weed extractors or cleaning appliances having such devices or such generators are proposed. The device or generator can be arranged, for example, at the bottom of the container of the watering can or in a separate volume of the watering can.

Furthermore, according to the invention, a method for generating fine bubbles, microbubbles and/or nanobubbles is proposed, which has the following steps:

a. the incorporation of gas bubbles into the liquid stream,

b. the liquid/gas mixture is guided through a static mixer or micro-bubble generator,

c. the liquid/gas mixture is directed through a nozzle,

d. the collision plate is loaded with a liquid/gas mixture.

As mentioned above, the method provides a cost-effective method for providing fine bubbles, micro-bubbles and/or nano-bubbles. In particular, a plurality of generators arranged in series can be dispensed with.

Detailed Description

Fig. 1 shows a watering can 10 for watering plants (not shown) having a container 12, a handle 14 and a spout 16. A generator 18 or device 20 for generating fine bubbles, microbubbles and/or nanobubbles is arranged in the container 12 of the watering can 10. The generator 18 or the device 20 is only schematically shown. With regard to various embodiments of such generators, reference is made to WO2014/184585 a2 page 9 lines 12 to 24, in which different fine-bubble generators are mentioned and described. It is therefore assumed that the skilled person knows at least the structure of the generators 18 or devices mentioned there, such as venturi bubble generators, swirl bubble generators, mixing bubble generators, cavitation bubble generators, pressurized dissolving bubble generators. These types of generators 18 are also described in figures 8a-8v and in the description of the related figures on pages 16 to 20 of WO2014/184585 a 2. The watering can 10 can also have a device 100 according to fig. 3 for generating fine bubbles, microbubbles and/or nanobubbles. Generator 18 or device 20 is supplied with energy via an energy store 22. The energy storage means can be embodied as a removable accumulator 24 (rechargeable) or a dry cell battery 26.

Similar to fig. 1, fig. 2 shows a watering can 10 for watering plants (not shown) having a container 12, a handle 14 and a spout 16. A generator 18 or device 20 for generating fine bubbles, microbubbles and/or nanobubbles is arranged in the container 12 of the watering can 10. Unlike fig. 1, the watering can 10 has a contact base 28 and/or a docking station 30. The watering can 10 is connected via a contact base and/or a docking station at least for supplying energy to the device 20 or the generator 18. Alternatively, the watering can 10 can also have other interfaces for energy supply. Data can also be transferred or read through the contact base 28, docking station 30, or interface. Additionally, the watering can 10 can have an energy store (not shown) as shown in fig. 1 that can be charged by contacting the base 28 or the docking station 30.

Furthermore, the watering can 10 or the docking station 30 according to fig. 1 and 2 can have a device 32 for determining and/or monitoring the time and/or the amount of bubble generation and/or the bubble size and/or the water temperature. For this purpose, the watering pot 10 or the docking station 30 has, for example, a control or regulating device 34 and/or a sensor 36. Furthermore, the watering pot 10 and the contact base 28 or the docking station 30 have an interface 38 for inputting adjustment parameters and/or an interface 40 for outputting and/or visualizing the generated parameters and/or signals. Finally, the watering can 10 or the docking station 30 can also have one or more switches 42 to turn on or control the generator 18.

Furthermore, the watering can 10 can have a device 44 for admixing fertilizers and/or herbicides, insecticides and/or fungicides, in particular from one or more reservoirs 46 for fertilizers, herbicides, insecticides or fungicides, in particular in the form of cartridges or storage rods. The reservoir can be arranged, for example, in the region of the spout 16, or the mixing of the pouring liquid can take place in the region of the spout 16 or of the pouring tube. Furthermore, the watering can 10 can also have a device 48 for generating a plasma-activated liquid.

Fig. 3 shows an apparatus 100 for generating fine bubbles, microbubbles and/or nanobubbles having a pump (not shown) for transporting a liquid 104 incorporating bubbles 102 through a fine bubble generator 106 and a nozzle 108 followed by the fine bubble generator. Downstream of the nozzles 108, an impingement plate 110 is arranged, on which the gas bubbles 102 are again thinned or comminuted to a smaller extent after they have been discharged from the nozzles 108 and upon impact on the impingement plate 110. The device 100 can be used, for example, in a watering can according to fig. 1 or 2 or in a weeder or cleaning appliance or the like.
