While manual cleaning and maintenance are relatively convenient for small, household food purifiers, large or industrial-grade purifiers often require disassembly or rely on complex automated systems. These larger, rectangular tanks are filled with the hydroxyl-releasing core components, making manual disassembly and maintenance extremely difficult and time-consuming.

[0003] Therefore, a device that facilitates the maintenance of the core components of a food purification machine has become a goal pursued by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of difficult maintenance of existing purification equipment.

[0005] To achieve the above-mentioned objectives, the technical solution of this utility model is as follows: a maintenance device for a food purifier, characterized in that it includes: a movable trolley, a liftable support on the trolley, a maintenance box that can be quickly and easily installed on the support, and a drain valve and a drain pipe connected to the drain valve for introducing maintenance liquid into the food purifier.

[0006] As a preferred embodiment, the upper end of the bracket has a horizontally positioned tabletop; the lower end of the maintenance box has an upwardly recessed groove, and when the maintenance box is installed on the tabletop, the tabletop is embedded in the groove.

[0007] As a preferred embodiment, the groove of the maintenance box is surrounded by four downwardly extending upright plates, with pin holes at both ends of two opposite upright plates. Nuts are provided at the outer ends of the pin holes, and quick-connect pins are laterally connected to the nuts for insertion under the tabletop plate to provide a limit.

[0008] As a preferred embodiment, the quick-connect pin includes a pin mounting base. The front end of the pin mounting base has an external thread for connection with a nut, and the rear end of the pin mounting base is a rearwardly extending annular support portion with two symmetrically arranged notches. A pin is inserted into the through hole of the pin mounting base, and the outer edge of the pin has an annular insert portion that mates with the notch of the rear support portion of the pin mounting base. A spring is provided between the pin and the pin mounting base, and the spring provides a pushing force to the pin, causing it to extend towards the pin hole. When the pin is inserted into the pin hole, the front end of the pin is inserted into and held below the tabletop plate. When the pin is pulled out and rotated 90 degrees, the front end of the annular insert portion of the pin is stopped and remains in contact with the end face of the rear support portion of the pin mounting base.

[0009] As a preferred embodiment, the trolley includes a rectangular frame, a pull rod extending upward from one end of the frame, and four wheels on the underside of the frame.

[0010] As a preferred embodiment, a slide rail 1 is provided on the inner side of a pair of longitudinal sidewalls of the vehicle body frame, and a corresponding slide rail 2 is provided on the inner side of the lower part of the platform plate along the longitudinal direction; the bracket is foldable and includes two sets of four equal-length rods: rod 1, rod 2, rod 3, and rod 4. The middle positions of the two sets of rods 1 and 2 are hinged together by a hinge shaft 1, and the middle positions of the two sets of rods 3 and 4 are hinged together by a hinge shaft 2. The lower ends of rods 3 and 4 are respectively hinged to the upper ends of rods 1 and 2; the lower end of rod 1 is fixedly connected to one end of slide rail 1, the lower end of rod 2 has a sliding pin 1 that can slide in slide rail 1 of the vehicle body frame, the upper end of rod 3 is fixedly connected to the end of the platform plate, and the upper end of rod 4 has a sliding pin 2, which is slidably connected to slide rail 2 on the lower inner side of the platform plate.

Detailed Implementation

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but these preferred embodiments should not be used to limit the scope of protection of the present invention.

[0025] Referring to Figure 1, Figure 1 is a schematic diagram of the maintenance device 100 of the food purification machine described in this utility model being applied to the food purification machine 200 for purification.

[0026] Referring to Figure 2-8, the figure shows a maintenance device for a food purifier, which includes: a movable trolley 1, a height-adjustable support 2 on the trolley 1, and a maintenance box 3 that can be quickly and easily installed on the support 2. The maintenance box 3 is preferably cuboid in shape. The lower part of the maintenance box 3 is provided with a drain valve 4 and a drain pipe 5 connected to the drain 4. Above the drain valve 4 of the maintenance box 3, there is a hook 35 for storing and hanging the drain pipe 5. In use, the maintenance box 3 can be quickly installed on the support 2, and the trolley 1 can be pushed to the vicinity of the food purifier 200. The maintenance box 3 contains a pre-prepared maintenance solution, which is introduced into the core component inside the food purifier 200 through the drain valve 4 and the drain pipe 5 to maintain and clean the water tank. It has the advantages of simple structure, easy disassembly and assembly, and flexible movement. When it is necessary to clean and maintain the core component of the food purifier, it is not necessary to disassemble the equipment to remove the core component or rely on complex equipment for operation.

[0027] Specifically, in the maintenance equipment of the food purification machine described in this utility model, the upper end of the support 2 has a horizontally set tabletop 27; the lower end of the maintenance box 3 has an upwardly recessed groove 31, which is formed by four downwardly extending vertical plates. The groove 31 is adapted to the tabletop 27. When the maintenance box 3 is installed on the tabletop 27, the tabletop 27 is embedded in the groove 31. The advantage is that the maintenance box 3 can be prevented from moving on the tabletop 27 during the movement of the maintenance equipment.

[0028] Furthermore, the maintenance box 3 is equipped with a quick-connect pin 33, which forms a limit with the tabletop plate 27 to restrict the maintenance box 3 from flipping. Specifically, pin holes are provided at both ends of two opposite sides of the upright plate forming the groove 31 in the maintenance box 3, that is, a pin hole is provided at the lower part of both ends of one upright plate, for a total of 4 pin holes. Nuts 34 are provided at the outer ends of the pin holes, which can be fixed to the outer side of the upright plate by welding, and the nut 34 is coaxial with the pin hole. A quick-connect pin 33 is connected laterally to the nut 34, so that it can be inserted under the tabletop plate 27, thereby providing a limit and effectively preventing the maintenance box 3 from flipping, providing safety and reliability during use. Since quick-connect pins are used, they can be quickly inserted and removed, making the disassembly and assembly operations convenient and quick.

[0029] Specifically, the quick-connect pin 33 includes a pin mounting base 331. The pin mounting base 331 has a through hole at its center for inserting the pin 332. The front end of the pin mounting base 331 has an external thread for connecting with the nut 34. The rear end of the pin mounting base 331 is a rearwardly extending annular support portion 3311 with two symmetrically arranged notches 3312. The pin 332 is inserted into the through hole of the pin mounting base 331. The outer edge of the rear part of the pin 332 has an annular insert portion 3321, which cooperates with the notch 3312 of the support portion 3311 of the pin mounting base 331. A spring 32 is provided between the pin 332 and the pin mounting base 331. The spring 32 provides a pushing force to the pin 332, causing it to extend towards the pin hole. Referring to Figure 7, when the pin 332 is inserted into the pin hole, the insert portion 3321 of the pin 332 is inserted into the notch 3312 of the support portion 3311 of the pin mounting base 331. The front end of the pin 332 is inserted and held below the tabletop plate 27 by the elastic force of the spring 32, thereby realizing the freedom of the maintenance box 3 to move upward, effectively avoiding the possibility of it overturning due to external force, and making it safe and reliable during operation. Referring to Figure 8, when the pin 332 is pulled out and rotated 90 degrees, the front end of the annular insert 3321 of the pin 332 contacts the end face of the support 3311. Therefore, the stop of the pin 332 support 3311 will not move forward. At the same time, the spring force of the spring 32 keeps the pin 332 at the rear end of the pin mounting base 331. The front end of the pin 332 is away from below the tabletop 27, and the maintenance box 3 can be removed. Under the action of the spring force, the pin 332 is always kept in the pin mounting base 331 and will not fall off. Thus, the quick-connect pin 33 enables quick installation and quick removal of the maintenance box 3, making the operation convenient and time-saving.

[0030] Furthermore, in a preferred embodiment of the maintenance equipment for the food purification machine described in this utility model, the trolley 1 includes a rectangular frame 11, a pull rod 12 extending upward from one end of the frame 11, and four casters 13 located below the frame 11. The trolley can be easily moved by pulling the pull rod. A first slide rail 111 is provided on the inner side of a pair of longitudinal sidewalls of the frame 11, and a second slide rail (not shown in the figure, but with the same structure as the first slide rail 111) is located on the inner side of the lower part of the tabletop 27 along the longitudinal direction. The bracket 2 is foldable and includes two sets of four equal-length rods: rod 1 21, rod 22, rod 3 23, and rod 4 24. The middle positions of rod 1 21 and rod 22 of the two sets are hinged together by hinge shaft 1 25, and the middle positions of rod 3 23 and rod 4 24 are hinged together by hinge shaft 2 26. The lower ends of rod 3 23 and rod 4 24 are hinged to the upper ends of rod 1 21 and rod 2 22, respectively. The lower end of rod 1 21 is fixedly connected to one end of slide rail 111. The lower end of rod 22 has a sliding pin 221 that can slide in slide rail 111 of the vehicle frame 11. The upper end of rod 3 23 is fixedly connected to the end of the platform plate 27. The upper end of rod 4 24 has a sliding pin 241, which is slidably connected to slide rail 2 on the lower inner side of the platform plate 27. A hydraulic cylinder 14 is mounted on the vehicle frame 11. The hydraulic cylinder 14 is connected to a crossbar 28 connected to the rod 21. By pushing the crossbar 28, the lower end of the rod 21 moves along the slide rail 111, thereby raising the bracket 2. The hydraulic cylinder 14 is connected to a foot pedal 15 for pressurization and a manual handle 16 for depressurization. By stepping on the foot pedal 15, pressure is applied to the hydraulic cylinder 14, pushing it to lift the bracket. When the manual handle 16 is pressed, pressure is released, causing the bracket to fall back down. Therefore, the bracket of this food purification machine can be raised and lowered manually without the need for a power supply, offering advantages such as simple structure and convenient and quick operation.
