Abstract
Description
Technical Field
[0001] This utility model relates to the field of fruit and vegetable preservation technology, and in particular to an atomization treatment device for fruit and vegetable preservation. Background Technology
[0002] As society develops, the requirements for the quality of fruits and vegetables are getting higher and higher. However, as fruits and vegetables move throughout the entire supply chain, from harvesting, sorting, storage, transportation to retail, the external environment in which they are located will change, such as temperature and humidity, which will negatively affect the quality of fruits and vegetables.
[0003] In terms of quality protection of fruits and vegetables, existing technologies mainly include chemical treatment technologies such as fumigation and chemical soaking, physical treatment technologies such as heat treatment, radiation, and low-temperature cold treatment, as well as comprehensive treatment using multiple methods. Different treatment methods have different advantages and disadvantages.
[0004] Currently, society's tolerance for pesticide residues in fruits and vegetables has decreased, making chemical treatments less ethical and less marketable. Regarding the overall preservation of fruits and vegetables, the coating preservation method mentioned in Chinese Patent 1 (Patent Name: Fruit and Vegetable Nano-Antibacterial Preservation Sprayer; Patent Application No.: 202210427366.1) is a method with good overall effects. However, different types of fruits and vegetables require different droplet sizes to achieve optimal results, and single-size applications have poor adaptability. Therefore, achieving a universal spray preservation effect for all fruits and vegetables requires higher standards for the spraying device. Furthermore, current antibacterial treatments on the surface of fruits and vegetables often employ chemical methods, resulting in significant residues and are not healthy treatment methods. Meanwhile, heat treatment and cold treatment preservation are also comprehensive preservation technologies. In existing devices and equipment, these specific preservation techniques are often implemented using only a single device; there is no integrated device that combines multiple technologies for fruit and vegetable preservation, resulting in low overall preservation efficiency and limited preservation effectiveness. Utility Model Content
[0005] In view of the problem that, in existing devices and equipment, the various specific preservation techniques mentioned above are often implemented using only a single device, this utility model provides an atomization treatment device for fruit and vegetable preservation, the solution of which is as follows:
[0006] A misting treatment device for preserving fruits and vegetables includes a main vehicle, on which a water tank, an electrical control box and a working arm are installed, and a spraying assembly is installed on the working arm;

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0028] refer to Figure 1-6 As shown, an atomization treatment device for preserving fruits and vegetables includes a main vehicle 100, on which a water tank 200, an electrical control box 300, and a working arm 400 are installed, and a spray assembly 500 is installed on the working arm 400.
[0029] like Figure 1 As shown, in some preferred embodiments, the main vehicle 100 includes a floor 110, with wheels 120 disposed on the lower surface of the floor 110 and handrails 130 disposed on the upper surface of the floor 110. When in use, personnel hold the handrails 130 to move the main vehicle 100 as a whole.
[0030] The spray assembly 500 is a device assembly that converts liquid into a spray and performs temperature control and electrification treatment on the spray. It includes various specific functional components and related structural and functional accessories. The spray assembly 500 includes a support shell 510, which is a structural component used to form the overall structural form. (Reference) Figure 3 As shown, a plurality of spray holes 511 are provided on the support housing 510. When the spray assembly 500 is in operation, the spray generated is ejected from the spray holes 511. A plurality of atomizing execution units 520 are provided inside the support housing 510, and each atomizing execution unit 520 corresponds one-to-one with a spray hole 511.
[0031] refer to Figure 2 As shown, the atomization execution unit 520 includes an atomizing plate 521, a semiconductor cooling chip 523, and an electrode plate 525. The atomizing plate 521 functions to atomize liquid. In specific implementations, the atomizing plate 521 is an ultrasonic atomizing plate, and the size of the atomized droplets is adjusted by controlling the vibration current of the atomizing plate 521, thus adapting to different fruits and vegetables and achieving better preservation results. The semiconductor cooling chip 523 is used for temperature control of the liquid mist, cooling or heating it to achieve heat preservation or cold preservation. The electrode plate 525 is used to electrify the liquid mist, making the droplets more evenly adhere to the surface of fruits and vegetables, reducing droplet rolling, and simultaneously, the high-voltage electrostatic field directly destroys the cell membranes of microorganisms, replacing chemical sterilization.
[0032] like Figure 2As shown, two thermoelectric coolers 523 are positioned in front of the atomizing plate 521, with their positions opposite each other. When the liquid mist generated by the atomizing plate 521 passes between the two thermoelectric coolers 523, it achieves heating or cooling of the liquid mist. To improve the temperature control effect of the liquid mist, a heat-conducting metal mesh 524 is connected between the two thermoelectric coolers 523. The function and role of the metal mesh 524 is to heat or cool the liquid mist through heat conduction by the metal material and thermal radiation, resulting in more uniform temperature control and better temperature control due to its proximity to the liquid mist. Electrode plates 525 for energizing the liquid mist are positioned opposite each other in front of the thermoelectric coolers 523. The electrode plates 525 are close to the spray hole 511 to ensure that the liquid mist exits the spray hole 511 as quickly as possible after electrical treatment, thus avoiding interference with electrical properties and temperature.
[0033] In some preferred embodiments, reference Figure 2 and Figure 4 As shown, the system also includes an atomizing mounting block 526, a cooling mounting block 527, and an electric field mounting block 528. The atomizing plate 521 is fixedly mounted on the atomizing mounting block 526, the semiconductor cooling chip 523 is fixedly mounted on the cooling mounting block 527, and the electrode plate 525 is fixedly mounted on the electric field mounting block 528. These three mounting blocks are sequentially and detachably embedded and secured by the support shell 510. The advantage and effect of independently configuring the atomizing mounting block 526, cooling mounting block 527, and electric field mounting block 528 is that the installation and removal of the atomizing plate 521, semiconductor cooling chip 523, and electrode plate 525 can be performed independently without interference, facilitating replacement and maintenance. In practical implementation, the spray hole 511 of the support shell 510 can be integrated by setting a threaded cap, which simultaneously abuts against the electrode plate 525 for installation.
[0034] In some preferred embodiments, reference Figure 2 and 4 As shown, the atomizing unit 520 also includes a liquid suction core 522, which is located behind and close to the atomizing plate 521. The function of the liquid suction core 522 is to prevent the liquid flow from forming a large, destructive impact force when it is supplied to the atomizing plate 521. In specific implementations, the liquid suction core 522 is made of foam or fiber, and uses capillary force to transport the liquid to the atomizing plate 521.
[0035] In some preferred embodiments, reference Figure 1As shown, it also includes a liquid pipe 600. One end of the liquid pipe 600 extends into the support housing 510 and is close to the atomizing plate 521, while the other end is connected to the water tank 200. A water pump 700 is provided between the water tank 200 and the liquid pipe 600 to pump water from the water tank 200 into the liquid pipe 600. The function of the liquid pipe 600 is to transport liquid from the water tank 200 to the atomizing execution unit 520 for subsequent liquefaction.
[0036] In some preferred embodiments, reference Figure 1 As shown, the power supply and control circuits of the atomizing plate 521, the thermoelectric cooler 523, and the electrode plate 525 are bundled together and connected to the electrical control box 300. The electrical control box 300 contains a control mainboard, and the atomizing plate 521, the thermoelectric cooler 523, and the electrode plate 525 are electrically connected to the control mainboard. The power supply and control circuits of the atomizing plate 521, the thermoelectric cooler 523, and the electrode plate 525 are externally connected by wires. To avoid interference, the wires of each atomizing actuator 520 are bundled together and extend into the electrical control box 300. The electrical control box 300 contains a control mainboard for controlling the atomizing plate 521, the thermoelectric cooler 523, and the electrode plate 525, and a human-machine interface module and a display module are connected to the control mainboard. Under different control commands, the atomizing plate 521 can produce liquid mist of different droplet sizes.
[0037] In some preferred embodiments, reference Figure 1 As shown, the operating arm 400 includes a first arm 410 and a second arm 420. One end of the second arm 420 is rotatably connected to the main body 100, and the other end is a free end. A groove is provided along the second arm 420, and one end of the first arm 410 is slidably disposed in the groove, while the other end is where the spraying assembly 500 is assembled. The function and effect of setting the first arm 410 and the second arm 420 is to adjust the position of the spraying assembly 500 by adjusting both arms to adapt to different fruit and vegetable conditions. The first arm 410 and the second arm 420 cooperate through a linear slide rail mechanism and a braking mechanism to achieve linear movement and braking at the required position.
[0038] In some preferred embodiments, one end of the second support arm 420 is connected to the main body vehicle 100 via a brake bearing, so that the second support arm 420 can be easily adjusted to a suitable operating angle.
[0039] In some preferred embodiments, reference Figure 1 As shown, the second arm 420 is a rod-shaped member formed by a telescopic rod mechanism.
[0040] In some preferred embodiments, reference Figure 1As shown, the water tank 200 and the electrical control box 300 are disposed on the upper surface of the vehicle floor 110, and one end of the second support arm 420 is rotatably connected to the upper surface of the vehicle floor 110.
[0041] In some preferred embodiments, a negative pressure system for providing thrust to the atomized water droplets is also included, the negative pressure system including a fan 810. In specific implementations, such as... Figure 5 As shown, the fan 810 is disposed within the support housing 510 and located behind the atomizing plate 521, so that when the fan 810 is driven, the flowing air can blow the liquid mist out of the support housing 510 at a relatively high speed, quickly contacting the surface of the fruits and vegetables. The control circuit wires and power circuit wires of the fan 810 are bundled together in the aforementioned wiring harness and connected to the electrical control box 300. In some other embodiments, such as Figure 6 As shown (fan 810 is not shown in the figure), the negative pressure system also includes a duct 820. The fan 810 is mounted on the main body 100 or inside the electrical control box 300. The outlet of the fan 810 is connected to the duct 820, and the end of the duct 820 extends into the support housing 510, so that the airflow generated by the fan 810 flows out through the duct 820 and blows the liquid mist out of the support housing 510.
[0042] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
