Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a mobile negative ion water washing device. Background Technology

[0002] In the production process of prickly pear juice, the juice, rich in vitamin C, organic acids, and various natural nutrients, possesses physicochemical properties that make it an ideal environment for microbial growth. If impurities, bacteria, or residues from previous processing remain on the inner walls of the bottling bottles, these contaminants will react with the nutrients in the juice, causing it to spoil rapidly during storage, deteriorate in flavor, and reduce product quality. Furthermore, it may foster the growth of harmful bacteria, posing a direct threat to the health of consumers. Therefore, thoroughly cleaning the inner walls of the bottling bottles before bottling is crucial for ensuring product quality and drinking safety. The core requirements are that the bottles are free of visible stains and that microbial indicators strictly meet standards.

[0003] In existing technologies, to meet the above cleaning standards, a cleaning solution containing detergent is commonly used to treat the inner wall of the filling bottle. The specific process consists of two stages: first, the operator uses a brush dipped in detergent to scrub the inner wall of the bottle, or uses a high-pressure water gun to spray detergent to rinse the inner wall; after initial cleaning, the inner wall is then rinsed with plenty of clean water to remove any residual detergent. During this process, the following technical problems may arise:

[0004] 1. Blind spots exist, resulting in incomplete cleaning of some areas: Whether brushing or rinsing with a high-pressure water gun, the coverage area is highly dependent on the operator's skill level. Specifically, when the operator does not brush thoroughly or the water gun spray angle is inaccurate, blind spots will exist, leading to incomplete cleaning of some areas.

[0005] 2. High water consumption: Because the detergent itself has chemical residues, it must be rinsed repeatedly with clean water to completely remove the residues in order to avoid affecting the quality of the juice. This process leads to a large waste of water resources, which contradicts the current industrial development concept of green environmental protection, energy conservation and emission reduction, and also increases the cost and pressure of wastewater treatment. Utility Model Content

[0006] The present invention aims to provide a mobile negative ion water washing device to solve the technical problems of existing technology when cleaning the inner wall of filling bottles. Due to insufficient brushing by operators or deviation of the water gun spray angle, there are blind spots in cleaning, resulting in some areas not being thoroughly cleaned. At the same time, the repeated rinsing with clean water by operators leads to a large amount of water consumption.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] 1) A mobile negative ion water washing device, comprising a support frame, a water tank for loading negative ion water is placed on the support frame, a placement plate is provided above the water tank, the placement plate is fixedly connected to the support frame, the placement plate is provided with a plurality of placement holes for placing filling bottles with the bottle mouth facing downwards, and a spray structure is provided between the placement plate and the water tank for spraying negative ion water toward the placement holes.

[0009] Before rinsing the inner wall of the bottle, the bottle to be cleaned is inverted and inserted into the placement hole of the placement plate with its mouth facing down. Then, the spray structure is activated to spray negative ion water into the bottle. The negative ion water decomposes residual organic matter and microorganisms on the bottle wall through physical adsorption and oxidation. The water flow completely covers and rinses the inner wall of the bottle from top to bottom, and finally, the dirt attached to the inner wall of the bottle is discharged with the water flow. Its working principle is to use the strong oxidizing and high permeability of negative ion water to replace chemical detergents, directly destroy the microbial cell structure and remove stains, eliminating the need for chemical rinsing.

[0010] This invention reduces blind spots in cleaning caused by manual operation, ensuring that the inner wall of the filling bottle is basically sprayed with negative ion water, resulting in a more thorough cleaning of the inner wall of the filling bottle; at the same time, since it does not require chemical detergents and repeated rinsing with water, compared with the existing technology that uses detergent-containing cleaning solution to treat the inner wall of the filling bottle, it can significantly reduce water consumption and is in line with the concept of green and environmentally friendly development.

[0011] 2) According to 1), a mobile negative ion water washing device is provided, wherein: the spray structure includes a main pipe and multiple branch pipes, one end of the main pipe is connected to a water storage tank, and the other end of the main pipe is connected to multiple branch pipes, the position of the branch pipe corresponds one-to-one with the position of the placement hole, and the branch pipe extends toward its corresponding placement hole.

[0012] The negative ion water in the main pipe can be distributed to individual sub-pipes and precisely injected into the inverted bottles placed in the placement holes. The ends of the sub-pipes extend deep into the bottle body, ensuring that the water flow back from the bottom of the bottle and covers the inner wall of the bottle. The positions of the sub-pipes correspond one-to-one with the placement holes, allowing for simultaneous rinsing of the inner wall of each inverted bottle in the placement hole. Compared to existing technologies that require manual cleaning of each bottle individually, this is more automated and efficient.

[0013] 3) A mobile negative ion water washing device according to 2), wherein: an installation box is provided in the water storage tank, a suction pump is provided in the installation box, the suction port of the suction pump is connected to an input pipe, the input pipe extends out of the installation box and is located in the water storage tank; the discharge port of the suction pump is connected to an output pipe, the output pipe extends out of the installation box and is connected to the main pipe.

[0014] The inlet pipe directly draws negative ion water from the storage tank via a suction pump, while the outlet pipe delivers the pressurized negative ion water to the main pipe. The suction pump ensures a stable water pressure supply to both the main and branch pipes, increasing the impact force and resulting in better cleaning. In this invention, mechanical seals are used between the inlet pipe, outlet pipe, and mounting box to physically isolate the suction pump from the negative ion water, preventing short circuits caused by contact between the pump and the negative ion water. The mounting box, located inside the storage tank, facilitates heat dissipation for the suction pump. Integrating the suction pump into the storage tank reduces space requirements.

[0015] 4) A mobile negative ion water washing device according to 2), wherein: the branch pipe includes a transport section for transporting negative ion water and a spray section for dispersing and spraying negative ion water, the transport section is connected to the main pipe, the spray section is located inside the filling bottle, the top of the spray section is a closed arc shape, and the side wall of the spray section is evenly provided with a plurality of spray holes for spraying negative ion water.

[0016] After the spray section extends into the filling bottle, negative ion water is sprayed out radially through evenly distributed spray holes on the side wall of the spray section. The arc-shaped design of the top of the spray section allows the water flow to be sprayed at multiple angles, enabling a wider range of rinsing of the inner wall of the filling bottle, while avoiding splashing caused by water flowing directly to the bottom of the bottle. This invention can increase the rinsing coverage of the water flow on the inner wall of the filling bottle, reduce cleaning blind spots, and make the cleaning effect better.

[0017] 5) A mobile negative ion water washing device according to 3), wherein: a sewage tank is provided on the water storage tank, the top of the sewage tank has an opening for receiving negative ion water after spraying, a through hole is provided on the lower surface of the sewage tank for the main pipe to pass through, all branch pipes connected to the main pipe are located inside the sewage tank, a sewage outlet is provided on the periphery of the sewage tank, and a sewage pipe extending into the sewage tank is installed in the sewage outlet.

[0018] After spraying, the negative ion water naturally falls into the wastewater tank and is then centrally collected through a drain pipe. The entire spraying structure is surrounded by the wastewater tank, and the main pipe passes through the wastewater tank via a through-hole and connects to a water storage tank. This invention can centrally treat the negative ion water after spraying, reducing environmental treatment costs.

[0019] 6) A mobile negative ion water washing device according to 1), wherein: a gas storage box for loading negative ion gas is provided on the top of the water storage tank, the gas storage box is connected to the water storage tank through an exhaust pipe, a water inlet is provided on the periphery of the water storage tank, and a water inlet pipe extending toward the inside of the water inlet is installed in the water inlet.

[0020] A gas storage tank containing negative ions continuously injects negative ion gas into a water storage tank through an exhaust pipe. An external water source is connected to replenish the gas. The water mixes with the negative ion gas within the tank, ultimately forming negative ion water. The negative ions in the negative ion water can disrupt the cell membrane potential of microorganisms, causing the cells to inactivate and settle. This invention uses negative ion water to clean filling bottles, eliminating the need for repeated rinsing with clean water to remove residual detergent, thus conserving water resources compared to existing technologies that use detergents.

[0021] 7) A mobile negative ion water washing device according to 6), wherein: the air storage box is connected to an air inlet pipe, an air pump is installed on the air inlet pipe, and a negative ion generator is installed inside the air storage box.

[0022] Outside air is pumped into the air storage tank by an air pump. The negative ion generator applies a high-voltage electric field, causing the outer electrons of air molecules to gain energy and break free from the atomic nucleus, forming free electrons. These free electrons quickly combine with surrounding neutral molecules, thereby generating negatively charged negative ions and forming negative ion gas.

[0023] 8) A mobile negative ion water washing device according to 1), wherein: a plurality of placement holes are evenly spaced, the cross section of the hole wall of the placement hole is an inverted isosceles trapezoid, and a first silicone layer is fixedly provided on the hole wall of the placement hole, the shape of the first silicone layer being adapted to the hole wall of the placement hole.

[0024] When the filling bottle is inserted into the placement hole inverted, the wall of the placement hole, which has an inverted isosceles trapezoidal cross-section, can hold filling bottles of different diameters through the first silicone layer. The silicone can deform to adapt to the bottle neck, achieving flexible fixation while avoiding scratches on the bottle neck.

[0025] 9) A mobile negative ion water washing device according to 1), wherein: a telescopic pump is fixedly connected to the top of the bracket, a pressure plate is fixedly connected to the free end of the output shaft of the telescopic pump, the lower surface of the pressure plate is set corresponding to the upper surface of the placement plate, and a holding space is formed between the lower surface of the pressure plate and the upper surface of the placement plate.

[0026] After the workshop workers place the bottle upside down into the placement hole, they turn on the telescopic pump to extend the output shaft, which in turn causes the pressure plate to move downward toward the placement plate. When the lower surface of the placement plate abuts against the bottom of the bottle, the output shaft stops extending, thus restricting the position of the bottle. When the spray section washes the inner wall of the bottle, it prevents the bottle from being lifted up due to excessive water pressure.

[0027] 10) A mobile negative ion water washing device according to 9), wherein: a second silicone layer is fixedly provided on the lower surface of the pressure plate.

[0028] When the pressure plate is pressed down, because a second silicone layer is fixed on its lower surface, the contact between the pressure plate and the bottom of the bottle is elastic. Compared with the pressure plate directly contacting the bottom of the bottle, this avoids the bottle breaking caused by rigid contact between the pressure plate and the bottom of the bottle.

[0029] The beneficial effects of this utility model are as follows:

[0030] This invention utilizes a one-to-one correspondence between the spray pipes and placement holes in the spray structure to precisely and completely cover the inner wall of inverted filling bottles with negative ion water. The arc shape at the top of the spray section and the evenly distributed spray holes on the side walls, combined with the strong oxidizing and high permeability of negative ion water, can flush and decompose residual organic matter and microorganisms from multiple angles, reducing cleaning blind spots caused by manual operation. The telescopic pump and pressure plate, along with the second silicone layer to fix the bottle body, further ensure the stability and reliability of the rinsing process. In addition, this invention uses negative ion water instead of traditional chemical detergents, eliminating the need for chemical rinsing and subsequent repeated rinsing, directly reducing water consumption from the source, which aligns with the concept of green and environmentally friendly development. The wastewater tank centrally collects the negative ion water after spraying, facilitating centralized treatment. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0041] See Figure 1 This utility model discloses a mobile negative ion water washing device, including a support 1. A water storage tank 2 for loading negative ion water is fixed on the support 1 by bolts and nuts. A placement plate 3 is provided above the water storage tank 2. The placement plate 3 is welded to the support 1. The placement plate 3 has multiple placement holes for placing bottles with their mouths facing down. A spray structure is provided between the placement plate 3 and the water storage tank 2 to spray negative ion water toward the placement holes.

[0042] Before rinsing the inner wall of the bottle, the bottle to be cleaned is inverted and inserted into the placement hole of the placement plate 3 with its mouth facing down. Then, the spray structure is activated to spray negative ion water into the bottle. The negative ion water decomposes residual organic matter and microorganisms on the bottle wall through physical adsorption and oxidation. The water flow completely covers and rinses the inner wall of the bottle from top to bottom, and finally, the dirt attached to the inner wall of the bottle is discharged with the water flow. Its working principle is to use the strong oxidizing and high permeability of negative ion water to replace chemical detergents, directly destroy the microbial cell structure and remove stains, eliminating the chemical rinsing step. This utility model can reduce cleaning blind spots caused by manual operation, ensure that the inner wall of the bottle is basically sprayed with negative ion water, and make the cleaning of the inner wall of the bottle more thorough. At the same time, since there is no need for chemical detergents and repeated rinsing with water, compared with the existing technology that uses washing liquid containing detergent to treat the inner wall of the bottle, it can significantly reduce water consumption and conform to the concept of green and environmentally friendly development.

[0043] In this embodiment, the spray structure includes a main pipe 4 and multiple branch pipes 5. One end of the main pipe 4 is connected to the water storage tank 2, and the other end of the main pipe 4 is connected to the multiple branch pipes 5. The positions of the branch pipes 5 correspond one-to-one with the positions of the placement holes, and the branch pipes 5 extend towards their corresponding placement holes. The negative ion water in the main pipe 4 can be diverted to each branch pipe 5 and accurately sprayed into the filling bottles placed upside down in the placement holes. The ends of the branch pipes 5 extend into the depth of the filling bottle, ensuring that the water flow back up from the bottom of the filling bottle and covers the inner wall of the filling bottle. The one-to-one correspondence between the positions of the branch pipes 5 and the placement holes allows for simultaneous rinsing of the inner wall of each filling bottle placed upside down in the placement hole. Compared with the prior art, which requires manual cleaning of each filling bottle, this method is more automated and more efficient.

[0044] In this embodiment: a mounting box 6 is fixed inside the water storage tank 2 by bolts and nuts. A suction pump 7 is installed inside the mounting box 6 by bolts and nuts. The suction port of the suction pump 7 is connected to an input pipe 8. The input pipe 8 extends out of the mounting box 6 and is located inside the water storage tank 2. The discharge port of the suction pump 7 is connected to an output pipe 9. The output pipe 9 extends out of the mounting box 6 and is connected to the main pipe 4.

[0045] The input pipe 8 directly draws negative ion water from the storage tank 2 via the suction pump 7, and the output pipe 9 delivers the pressurized negative ion water to the main pipe 4. The suction pump 7 ensures a stable water pressure supply to the main pipe 4 and branch pipes 5, increasing the impact force and improving the cleaning effect. In this invention, mechanical seals are used between the input pipe 8, the output pipe 9, and the mounting box 6 to physically isolate the suction pump 7 from the negative ion water, preventing short circuits caused by contact between the suction pump 7 and the negative ion water. Simultaneously, the mounting box 6, located inside the storage tank 2, facilitates heat dissipation for the suction pump 7. Integrating the suction pump 7 into the storage tank 2 reduces space requirements.

[0046] See Figure 1 , Figure 2In this embodiment, the branch pipe 5 includes a transport section for transporting negative ion water and a spray section for dispersing and spraying negative ion water. The transport section is connected to the main pipe 4, and the spray section is located inside the filling bottle. The top of the spray section is a closed arc shape, and the side wall of the spray section is evenly provided with several spray holes 10 for spraying negative ion water. After the spray section extends into the filling bottle, the negative ion water is sprayed out radially through the evenly distributed spray holes 10 on the side wall of the spray section. The arc shape design of the top of the spray section allows the water flow to be dispersed and sprayed at multiple angles, which can rinse the inner wall of the filling bottle more widely, while avoiding water flow directly hitting the bottom of the bottle and causing splashing. This utility model can increase the rinsing coverage of the water flow on the inner wall of the filling bottle, reduce cleaning blind spots, and make the cleaning effect better.

[0047] See Figure 1 In this embodiment: a wastewater tank 11 is fixed to the water storage tank 2 by bolts and nuts. The top of the wastewater tank 11 has an opening for receiving the negative ion water after spraying. A through hole is provided on the lower surface of the wastewater tank 11 for the main pipe 4 to pass through. All branch pipes 5 connected to the main pipe 4 are located inside the wastewater tank 11. A drain outlet is provided on the periphery of the wastewater tank 11, and a drain pipe 12 extending into the wastewater tank 11 is threaded into the drain outlet. The negative ion water after spraying falls naturally into the wastewater tank 11 and is centrally collected through the drain pipe 12. The entire spraying structure is surrounded by the wastewater tank 11, and the main pipe 4 passes through the through hole and connects to the water storage tank 2. This utility model can centrally treat the negative ion water after spraying, which can reduce the cost of environmental protection treatment.

[0048] In this embodiment: a gas storage tank 20 for loading negative ion gas is fixedly connected to the top of the water storage tank 2 by bolts and nuts. The gas storage tank 20 is connected to the water storage tank 2 through an exhaust pipe 14. A water inlet is opened on the periphery of the water storage tank 2, and a water inlet pipe 15 extending into the water storage tank 2 is threadedly connected to the water inlet. The gas storage tank 20 is connected to an air inlet pipe 21, and an air pump is installed on the air inlet pipe 21. A negative ion generator 13 is installed inside the gas storage tank 20.

[0049] Outside air is pumped into the air storage tank 20 by an air pump. The negative ion generator 13 applies a high-voltage electric field, causing the outer electrons of air molecules to gain energy and break free from the atomic nucleus, forming free electrons. These free electrons quickly combine with surrounding neutral molecules, generating negatively charged negative ions and forming negative ion gas. The air storage tank 20, filled with negative ion gas, continuously injects negative ion gas into the water storage tank 2 through the exhaust pipe 14. The water inlet is connected to an external water source to replenish the consumption. The water mixes with the negative ion gas in the storage tank, eventually forming negative ion water. The negative ions in the negative ion water can disrupt the cell membrane potential of microorganisms, causing the bacteria to become inactive and settle. This invention uses negative ion water to clean the filling bottles, which, compared to the existing technology that uses detergent, eliminates the step of repeatedly rinsing with clean water to remove residual detergent, thus saving water resources.

[0050] See Figure 3 In this embodiment: multiple placement holes are evenly spaced, and the cross-section of the hole wall is an inverted isosceles trapezoid. A first silicone layer 16 is adhered to the hole wall, and the shape of the first silicone layer 16 is adapted to the hole wall. When the filling bottle is inserted into the placement hole inverted, the inverted isosceles trapezoidal cross-section of the hole wall, through the first silicone layer 16, can clamp filling bottles of different diameters. The silicone can deform to adapt to the bottle neck, achieving flexible fixation while avoiding scratches on the bottle neck.

[0051] See Figure 1 In this embodiment: a telescopic pump 17 is fixedly connected to the top of the bracket 1 by bolts and nuts. The telescopic pump 17 has an output shaft extending toward the placement plate 3. A pressure plate 18 is fixedly connected to the free end of the output shaft by bolts and nuts. The lower surface of the pressure plate 18 corresponds to the upper surface of the placement plate 3, and a holding space is formed between the lower surface of the pressure plate 18 and the upper surface of the placement plate 3. After the workshop worker places the bottle mouth down into the placement hole, the telescopic pump 17 is turned on, causing the output shaft to extend, which in turn causes the pressure plate 18 to move downward toward the placement plate 3. When the lower surface of the placement plate 3 abuts against the bottom of the bottle, the output shaft stops extending further, and the position of the bottle is restricted. When the spray section of the branch pipe 5 rinses the inner wall of the bottle, it can prevent the bottle from being washed away due to excessive water pressure.

[0052] See Figure 4 In this embodiment, a second silicone layer 19 is bonded to the lower surface of the pressure plate 18. When the pressure plate 18 is pressed down, because the second silicone layer 19 is bonded to its lower surface, its contact with the bottom of the filling bottle is elastic. Compared with the pressure plate 18 directly contacting the bottom of the filling bottle, this avoids the filling bottle breaking caused by the pressure plate 18 directly contacting the bottom of the filling bottle.

[0053] The above are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
