Description

[0001] The proposed technical solution relates to the field of bottled water consumption, namely to devices for preparing and dispensing water from bottles and is intended for use in offices, homes, business centers, gyms, etc., is of the electric type, charged via a USB cable.

[0002] The electric water pump provides convenient pumping of water from standard 19-liter bottles into glasses or teapots, without having to tilt the heavy bottle.

[0003] A known electric water pump transmits information about the amount of water in a bottle to one or more cell phones upon receipt of incoming voice or text requests, or in accordance with a program algorithm implemented by a microprocessor with remote water level control. The pump comprises a sensor measuring the pressure created by the water column and the rarefied air in the bottle, a normalizing amplifier, a power supply with a battery, a microprocessor with random access and read-only memory, an information display indicator, a SIM card holder with a controller, a transceiver, a power amplifier, and an antenna with a switch. The sensor and normalizing amplifier generate a signal proportional to the pressure created by the water column and the rarefied air in the bottle. This signal is fed to the information processing system, whose operation is provided by a power supply with a battery.A microprocessor with RAM and ROM converts this signal in real time, according to a pre-programmed program, into a digital signal proportional to the water level or quantity, and displays it on the indicator. When implementing the remote control function, information about the water level or quantity in the bottle is converted by the microprocessor into a SMS signal, which is received by the transceiver, then amplified by a power amplifier and transmitted via an antenna with a switch to specific addresses of one or more telephones upon receipt of corresponding requests. Identification of the information processing system in the network is performed by a SIM card inserted into the SIM card holder with the controller. Requests about the water level or quantity can be voice or SMS messages.The microprocessor can also generate and send SMS messages about the amount of water in the bottle according to a program stored in the ROM (at specified intervals, when the water level or quantity in the bottle reaches a specified value, or a combined program). If the information processing system is supplemented with a display and keyboard, the dispenser owner can exchange SMS messages with the supplier responsible for replacing empty bottles (Russian Federation Patent No. 180374, IPC B67D 3 / 00, published June 8, 2018).

[0004] The disadvantages of this technical solution are the design complexity due to the design of the funnel, the presence of a pressure sensor, a SIM card holder with a controller, as well as the need to install the bottle with the neck down, which complicates maintenance and reduces the stability of the device with a full bottle installed.

[0005] A water bottle attachment is known. Its housing contains a capacitive sensor connected to a microcontroller that receives and processes the sensor's signal and transmits information about the bottle's low water level to a Wi-Fi wireless module with a built-in antenna for ordering a new bottle online, as well as a built-in battery for powering the bottle. The attachment's housing can be attached to the bottle using an elastic band (RU Patent No. 206259, IPC B67D 1 / 08, published September 2, 2021).

[0006] The device is implemented on the Arduino MKR1000 board based on the Atmel ATSAMW25 single-chip system, which contains a 32-bit ARM microcontroller, contains a WiFi chip, and a built-in antenna.

[0007] The device is triggered when the water in the bottle drops below the set level, processes and transmits information about the end of water in the bottle using wireless communication.

[0008] The disadvantage of this device is its inconvenience of use, since it is necessary to move the attachment to a new bottle each time, as well as separately monitor the discharge of its built-in battery.

[0009] The closest to the proposed technical solution is an electric water pump containing a housing, the base of which is complementary to the neck of the bottle, in the housing there is a microcontroller, control buttons, a power source, a pump, a power source charge indicator, the pump inlet is connected to a suction tube installed in the base of the housing, the pump outlet is connected to a spout tube located on the side of the housing, in the upper part of the housing there are buttons for continuous and portioned water supply and power source charge indicators, the power source, the pump electric drive, the power source charge indicator, the buttons for continuous and portioned water supply and the charge indicators are connected to the corresponding inputs / outputs of the microcontroller (https: / / www.vseinstrumenti.ru / product / elektricheskaya-pompa-dlya-vody-sonnen-ewd162wb-1-6-l-min-2-rezhima-akkumulyator-455468-5359609 / ?utm_source=yandex&utm_medium=cpc&utm_campaign=115394803|dsa_na_na_na_rf_sku-push-ank-b2b_prochie-mesta-pokaza&utm_content=1858454140569621791&utm _term=ST:search|S:none|AP:no|PT:premium|P:1|DT:desktop|RI:213|CI:115394803|GI:5507362529|PI:53506720952|AI:1858454140569621791| RT:53506720952|KW:---autotargeting|RN:%D0%9C%D0%BE%D1%81%D0%BA%D0%B2%D0%B0&referrer=reattribution=1&yclid=5800739874364194815).

[0010] A drawback of this device is the lack of remote bottle emptying and battery charge monitoring, which is significant when using a significant number of water coolers simultaneously in a single facility, such as offices and business centers. This is especially important when used in illuminated spaces, where the bottle may be covered with an optically opaque material to protect the water from sunlight, which can cause clouding.

[0011] The technical task that this proposal aims to solve is to expand the functionality of an electric water pump and improve its ease of use.

[0012] To solve this technical problem, an electric water pump is proposed, comprising a housing, the base of which is complementary to the neck of the bottle, a microcontroller, control buttons, a power source, a pump, a power source charge indicator are located in the housing, the pump inlet is connected to a suction tube installed in the base of the housing, the pump outlet is connected to a spout tube located on the side of the housing, in the upper part of the housing there are buttons for continuous and portioned water supply and power source charge indicators, the power source, the pump electric drive, the power source charge indicator, the buttons for continuous and portioned water supply and the charge indicators are connected to the corresponding inputs / outputs of the microcontroller, a Wi-Fi wireless communication module with a built-in antenna, the input of which is connected to the corresponding outputs of the microcontroller.The intake tube is made of mechanically hard plastic, such as polyethylene terephthalate (PET), the level sensor is made as a contact in the form of metal strips on the sides of the intake tube made of stainless steel or silver sprayed onto the intake tube.

[0013] The applicant did not find any other technical solutions with a similar purpose and a similar set of essential features during a search of scientific and technical literature and patent documentation. The proposed electric water pump can be manufactured from known materials using known equipment. The proposed technical solution can be easily implemented in the production of water dispensers at companies that manufacture such equipment. Therefore, the applicant believes that the proposal in this application meets the utility model protectability criteria of "novelty" and "industrial applicability."

[0014] The essence of the proposal is explained by drawings, which show a non-exclusive example of the proposed device.

[0015] Fig. 1 shows the functional diagram of the device. Fig. 2 shows an example of a sensor with a sampling tube.

[0016] The figures indicate:

[0017] Microcontroller 1, continuous water supply control button 2, portioned water supply control button 3, power source 5 charge indicators 4, pump 6 with electric drive, intake tube 7, spout tube 8, Wi-Fi wireless communication module 9 with built-in antenna, water presence sensor 10, metal strips 11 on the sides of intake tube 7, forming an embodiment of sensor 10,

[0018] The device works as follows:

[0019] A device with a pre-charged power source 5 (battery) and a suction tube 7 with metal strips 11 on the sides of the suction tube 7 is installed with its base on the neck of a bottle (not shown), while one end of the metal strips 11 on the sides of the suction tube 7, forming a contact level sensor, are connected to the corresponding input of the microcontroller 1. While the water level is sufficient, the water closes the metal strips 11, the microcontroller 1, when button 2 or 3 is pressed, turns on the electric drive of the pump 6, and water from the bottle is poured through tube 8 into the consumer's vessel.When the water in the bottle is exhausted, the contact between metal strips 11 connected to the corresponding input of microcontroller 1 is broken. Microcontroller 1 generates a signal containing information for ordering a new bottle and transmits it via Wi-Fi wireless module 9 via radio to a Wi-Fi base station (access point) located indoors and connected to the internet to transmit the order to facility staff. Furthermore, microcontroller 1 prevents buttons 2 or 3 from activating pump 6. This eliminates the possibility of damage to the device during dry running. When the voltage at the output of power source 5 decreases, microcontroller 1 similarly generates and transmits a signal indicating the need to recharge power source 5 (or replace the pump).

[0020] The applicant has manufactured and successfully tested prototypes of the proposed device using batteries with a capacity of at least 1200 microampere hours as a power source, which ensures the dispensing of at least 120 liters of water from a single charge.
