Description

Technical Field

[0001] The present invention relates to the field of liquid storage technology, and particularly to a liquid storage device with an atomizing injection function.

Background Art

[0002] With the improvement of people's living standards and the diversification of application scenarios, the needs for the functions of liquid storage devices have increased. Especially in the fields of outdoor cooling, irrigation in gardening, cleaning and disinfection, etc., it has become difficult for conventional liquid storage devices to meet modern usage requirements.

[0003] In the prior art, atomizing injection devices are mainly classified into two types. One is a device dedicated to atomization, and the other is simply a liquid storage container. The device dedicated to atomization has an atomizing function, but generally has a complex structure, a large volume, poor portability, and a high cost. For example, Chinese Patent CN213698523U discloses an atomizing nozzle and a spray-type handwashing and disinfecting device, which includes a liquid storage tank and an atomizing chamber, and an atomizing sheet is provided in the atomizing chamber. International Patent WO2017206022A1 discloses a liquid storage bottle and a liquid storage bottle assembly that use an ultrasonic atomizer to atomize a liquid, and a liquid suction member is inserted into the liquid storage chamber and extends to the bottom of the liquid storage chamber. Chinese Patent CN207641687U also discloses a liquid storage bottle based on an ultrasonic atomizer, in which the entire sealed body is constituted by an atomizing assembly, a liquid storage assembly, an electrode assembly, etc.

[0004] However, the above-mentioned conventional technologies have the following drawbacks. First, the problem of functional unity is significant; conventional water tanks can only store and supply water, lacking atomization and spraying capabilities, and therefore cannot meet diverse application needs such as outdoor cooling or use in combination with fans. Second, conventional spraying equipment generally has a complex structure, with each functional module designed separately, making integrated integration difficult. As a result, the equipment is bulky and not portable. Furthermore, conventional atomizing devices often employ ultrasonic atomization, which has high requirements for liquid purity, and the atomization effect is easily affected by changes in the liquid level, leaving room for improvement in stability. Finally, the human-machine interaction design of conventional equipment is incomplete, lacking convenient control methods and intuitive status indications, leaving room for improvement in the user experience.

[0005] Therefore, in order to meet the requirements of diverse modern application scenarios, there is an urgent need to develop a device that integrates liquid storage and atomization functions, which not only maintains the basic functions of conventional liquid storage containers but also achieves a stable and reliable atomization spray effect, while also having advantages such as a compact structure, excellent portability, and ease of operation.

Embodiments for Carrying out the Invention

[0019] Hereinafter, for the convenience of those skilled in the art, the present invention will be further described with reference to examples and drawings, and the content referred to in the embodiments does not limit the present invention.

[0020] Referring to FIGS. 1 to 11, a liquid storage device having an atomizing injection function includes three main parts: an atomizing unit 1, a cover assembly 2, and a liquid storage chamber 3.

[0021] The liquid storage chamber 3, as the main body structure of the entire device, is provided with an opening at the top for connecting to the cover assembly 2. A transparent window 32 is provided on the side wall of the liquid storage chamber 3. The transparent window 32 extends along the vertical direction, and the user can visually observe the height of the liquid level in the liquid storage chamber 3 through the transparent window 32, which facilitates timely replenishment of the liquid. An engaging portion 31 is symmetrically provided on the outer periphery of the top of the liquid storage chamber 3. The engaging portion 31 is designed with a snap-fit structure and can form a strong connection with the cover assembly 2.

[0022] The cover assembly 2 adopts an integrated design, and a water pump 41 is integrated inside as the core power source. A liquid supply pipe 6 is connected to the inlet end of the water pump 41. The liquid supply pipe 6 is made of a flexible material, and the distal end penetrates through the cover assembly 2 and extends to below the liquid level in the liquid storage chamber 3, ensuring that the liquid in the liquid storage chamber 3 can be effectively absorbed. A filtering unit 7 is provided at the distal end of the liquid supply pipe 6. The filtering unit 7 adopts a multi-layer filter mesh structure, which can effectively filter out solid impurities in the liquid in the liquid storage chamber 3, preventing impurities from entering the water pump 41 system and causing blockage or damage. The outlet end of the water pump 41 is in fluid communication with the inlet end of the atomizing unit 1 through a flexible guide pipe 5. A pressure-resistant hose is adopted for the flexible guide pipe 5, which can accommodate different mounting positions and angles.

[0023] The cover assembly 2 is fitted over the opening of the liquid storage chamber 3 in a removable, sealed manner. The cover assembly 2 is provided with a corresponding engaging portion 25, which, together with the engaging portion 31 of the liquid storage chamber 3, forms a quick-lock mechanism. The quick-lock mechanism employs a rotary locking method, allowing the user to easily and quickly achieve a removable connection between the cover assembly 2 and the liquid storage chamber 3 by simply rotating it. The cover assembly 2 is further provided with a liquid replenishment passage 23 that communicates fluidly with the liquid storage chamber 3. A sealing member 24 is removablely provided at the outer end of the liquid replenishment passage 23. The sealing member 24 employs a rubber stopper structure, which effectively seals the liquid replenishment passage 23 under normal circumstances and can be easily removed when replenishment is necessary.

[0024] The top wall of the cover assembly 2 is recessed inward to form a gripping recess 21, and the shape of the gripping recess 21 conforms to ergonomic design, making it easy for the user to grip. A C-shaped gripping portion 22 is hinged to the side wall of the gripping recess 21, and the C-shaped gripping portion 22 is made of metal or hard plastic and has high strength and durability. The gripping portion 22 is rotatable between a retracted position and an extended position, in the retracted position the gripping portion 22 fits flat within the gripping recess 21 and does not affect the overall appearance, and in the extended position the gripping portion 22 stands upright, making it easy for the user to lift the entire device.

[0025] The cover assembly 2 further contains a power module 42 and a control module. The power module 42 employs a rechargeable lithium battery, providing a stable power supply to the entire system. The control module includes a printed circuit board 43, a human-machine interaction panel 44, and an electrical energy input interface 45. The printed circuit board 43 is fixed within the cover assembly 2 and integrates core electronic components such as a microprocessor, power management circuitry, and a drive circuit for the water pump 41. The human-machine interaction panel 44 is fitted onto the exposed surface of the cover assembly 2 and includes a power switch, operating mode selection buttons, and LED indicators, allowing the user to control the operating status of the device via the human-machine interaction panel 44. The electrical energy input interface 45 is located on the side wall of the cover assembly 2 and employs a standard USB interface for easy charging and maintenance. The human-machine interaction panel 44, the electrical energy input interface 45, and the water pump 41 are all electrically coupled to the printed circuit board 43 to form a complete control circuit.

[0026] The control module, power supply module 42, and water pump 41 are all electrically connected, and the microprocessor in the control module can control the operating state of the water pump 41 based on parameters set by the user, including functions such as start and stop control, rotation speed adjustment, and operating time setting. The control module also has safety functions such as overload protection and undervoltage protection to ensure the stable and reliable operation of the system.

[0027] The atomization generation unit 1 is an important component for realizing the atomized spraying of liquid, and includes an atomizing nozzle 11, an intermediate member 12, a nozzle case 13, and a locking member 14, where multiple sets of atomizing nozzles 11 can be provided according to the actual needs. The nozzle case 13 is manufactured from a precision-machined metal material and is provided with a first housing opening 131 for housing the atomizing nozzle 11 and a second housing opening 132 for housing the intermediate member 12. The first housing opening 131 and the second housing opening 132 communicate via an internal passage to form a complete liquid flow path.

[0028] The intermediate member 12 is housed in the second housing port 132 and is made of engineering plastic, providing good corrosion resistance and sealing properties. The inlet end of the intermediate member 12 and the outlet end of the flexible guide pipe 5 are in airtight contact, and a strong connection is ensured by a screw connection method. The outlet end of the intermediate member 12 is designed as a conical connection port and engages precisely with the liquid supply end of the atomizing nozzle 11. A pressure relief passage 121 is provided inside the intermediate member 12, which is in fluid communication with the inner chamber of the nozzle case 13. If the pressure inside the system is too high, the pressure relief passage 121 can automatically relieve the excess pressure to balance the pressure inside the atomizing unit 1, preventing system failure or safety risks due to excessive pressure.

[0029] The atomizing nozzle 11 is manufactured from a precision ceramic or alloy material and has excellent wear resistance and chemical stability. The liquid supply end of the atomizing nozzle 11 passes through the first housing port 131 and is sealed against the liquid outlet end of the intermediate member 12, and the sealing of the connection point is ensured by an O-ring. Inside the atomizing nozzle 11, a multi-stage atomizing structure is provided, and as the liquid passes through the atomizing nozzle 11 under high pressure, it is sufficiently atomized to form fine and uniform mist droplets.

[0030] The locking member 14 removably seals the open end of the nozzle case 13 and engages with the nozzle case 13 in an engaging connection manner to restrict the axial position of the intermediate member 12, ensuring that the intermediate member 12 remains in a stable position during operation. The design of the locking member 14 makes it easy to remove, allowing the user to easily clean and maintain it.

[0031] The overall operating principle of the device is as follows: After the user starts the system via the man-machine interaction panel 44, the control module drives the water pump 41 to start operating. The water pump 41 draws liquid from the liquid storage chamber 3 via the liquid supply pipe 6, and the liquid is filtered by the filtration unit 7 before entering the water pump 41 and then sent to the atomization generating unit 1 via the flexible guide pipe 5. The liquid enters the relay member 12 under the pressure generated by the water pump 41, and subsequently flows into the atomization nozzle 11. Under the action of the multi-stage atomization structure of the atomization nozzle 11, the liquid is sufficiently atomized and sprayed, forming a uniform and fine mist spray effect. The pressure relief passage 121 performs a pressure balancing function throughout the entire process, ensuring the stability of the system pressure and the consistency of the spray effect.

[0032] This liquid storage device achieves multiple functions such as liquid storage, transport, and atomization through its integrated design. The coordinated operation of each component ensures stable and reliable liquid atomization and spraying, making it applicable to various horticultural applications such as irrigation, cleaning and disinfection, and humidification / temperature reduction.

Any obvious substitutions are protected within the scope of the present invention, as long as they do not depart from the concept of the present invention. [Explanation of symbols]
