Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, specifically a mobile pure water treatment device. Background Technology

[0002] Ultrapure water, also known as UP water, contains almost no impurities other than water molecules. It is free of bacteria, viruses, dioxins, and other organic matter, as well as essential minerals and trace elements. In other words, it is water with almost all atoms except oxygen and hydrogen removed.

[0003] A search revealed that patent document CN218046862U discloses a mobile ultrapure water treatment device, belonging to the technical field of water treatment equipment. This mobile ultrapure water treatment device includes a base assembly and a winding assembly. The base assembly includes a moving part, a push rod, a vertical plate, a filter part, and a locking part. The push rod and the vertical plate are both mounted on the moving part, the filter part is mounted on the vertical plate, and the locking part is mounted on the filter part. This ultrapure water treatment device allows for filter element replacement without completely disassembling the filter, reducing the operator's workload.

[0004] However, the above-mentioned patent also has the following defects: such as insufficient stability. The application only uses a single motor to drive the universal wheel to lift and support the device. The single-sided power output is prone to causing torque imbalance during the lifting process, which may lead to structural tilting or lateral displacement. In extreme cases, it may cause the risk of overturning. Furthermore, when the load center of gravity shifts, the single-sided drive is difficult to compensate for the attitude deviation in real time, resulting in a vibration amplification effect during the support process. Therefore, a mobile pure water treatment device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mobile pure water treatment device with advantages such as stable lifting and good support effect. It solves the problem that single-sided drive is difficult to compensate for attitude deviation in real time, which leads to vibration amplification effect during the support process and affects the support of the equipment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4This embodiment of a mobile pure water treatment device includes a base 1 and a pure water treatment device 2 fixed to the upper surface of the base 1. The pure water treatment device 2 includes a filter 201 and a bracket 202. The filter 201 is rotatably mounted inside the bracket 202. A locking rod is provided inside the bracket 202 to lock the filter 201. A support rod 203 fixed to the bottom side of the base 1 is welded to the bottom side of the bracket 202. A controller is fixed to the outer wall of the base 1. A handle is fixed to the upper surface of the base 1.

[0026] In this embodiment, the bottom side of the base 1 is provided with movable wheels 4 and a support mechanism 3 for lifting and lowering the movable wheels 4. The support mechanism 3 includes a mounting plate 301 and a drive motor 302 disposed on the bottom side of the base 1. A screw sleeve 303 is rotatably mounted on the bottom side of the base 1. A lifting screw 304 threadedly connected to the screw sleeve 303 is fixed on the upper surface of the mounting plate 301. A worm gear 305 is fixed on the output shaft of the drive motor 302. A worm wheel 306 meshing with the worm gear 305 is fixed on the outer surface of the screw sleeve 303. Specifically, the base 1 is U-shaped, and its concave surface is set downward, which provides a reasonable spatial layout for the installation of the movable wheels 4 and the support mechanism 3. It also helps to protect the movable wheels 4 and the support mechanism 3 from external collisions and other influences. There are four movable wheels 4, and the four movable wheels 4 are rotatably mounted on the lower surface of the mounting plate 301 in a rectangular shape.

[0027] It should be noted that the bottom end of the lifting screw 304 is fixed to the center of the upper surface of the mounting plate 301, and two symmetrically distributed guide rods 307 are fixed to the upper surface of the mounting plate 301. The base 1 has three extension slots 308 inside, and the top ends of the lifting screw 304 and the two guide rods 307 extend into the three extension slots 308 respectively. The drive motor 302 drives the worm gear 305 to rotate, which in turn drives the worm wheel 306 and the screw sleeve 303 to rotate, causing the lifting screw 304 to move up and down, thereby controlling the lifting of the mounting plate 301 and the moving wheel 4. This transmission method utilizes the self-locking characteristics of the worm gear 305 and the worm wheel 306, effectively preventing the moving wheel 4 from accidentally descending when the device is in a fixed state, ensuring the stability of the device.

[0028] In this embodiment, the mounting plate 301 has a mounting groove 311 inside, and a locking structure is provided inside the mounting groove 311; the base 1 has a locking hole 6 inside, which is used in conjunction with the locking structure, and a detection structure 5 for detecting the locking structure is provided inside the locking hole 6. Specifically, the locking structure includes a dual-axis motor 309 fixed in the middle of the mounting groove 311. Two bidirectional screws 312 are fixed on the two output shafts of the dual-axis motor 309. Two locking blocks 310 are slidably installed in the mounting groove 311. The two locking blocks 310 are symmetrically distributed on the left and right, and the two locking blocks 310 are threadedly connected to the two bidirectional screws 312 respectively.

[0029] The mounting plate 301 has two locking holes 6, which are positioned corresponding to two locking blocks 310, and each locking block 310 is inserted into one of the two locking holes 6. The mounting plate 301 has an internal battery compartment containing a battery module electrically connected to the dual-axis motor 309. The length of the locking blocks 310 is adapted to the locking distance. The design of the two locking blocks 310 and the two locking holes 6 increases the stability and reliability of the locking mechanism, avoiding loosening or failure that may occur at a single locking point. A maintenance housing is provided on the mounting plate 301.

[0030] To achieve locking detection, the detection structure 5 includes a mounting bracket 501 fixed to the inner wall of the locking hole 6. A detection rod 502 and an abutment block 504 are disposed on the side of the mounting bracket 501 near the locking block 310. One end of the detection rod 502 is fixed to the outer surface of the abutment block 504. A return spring 503 is fixed between the abutment block 504 and the mounting bracket 501, surrounding the detection rod 502. A through hole 505 adapted to the detection rod 502 is provided inside the mounting bracket 501. It should be noted that when the abutment block 504 is not compressed, the end of the detection rod 502 is located within the through hole 505, and the abutment block 504 is slidably connected to the inside of the locking hole 6. The signal fed back by the detection structure 5 can accurately determine whether the locking block 310 is fully inserted into the locking hole 6, thereby ensuring the reliability of the locking state. This detection function can promptly detect locking abnormalities and avoid safety hazards caused by incomplete locking.

[0031] The working principle of the above embodiments is as follows:

[0032] When the device needs to be moved, the drive motor 302 starts, and the worm 305 on its output shaft rotates. Since the worm 305 meshes with the worm wheel 306 on the outer surface of the threaded sleeve 303, it drives the threaded sleeve 303 to rotate. Also, since the lifting screw 304 on the upper surface of the mounting plate 301 is threadedly connected to the threaded sleeve 303, and two symmetrically distributed guide rods 307 are fixed on the upper surface of the mounting plate 301, the top of the lifting screw 304 and the tops of the two guide rods 307 extend into the three extension slots 308 opened inside the base 1, the rotation of the threaded sleeve 303 will cause the lifting screw 304 to move downward, thereby driving the mounting plate 301 to descend and making the moving wheel 4 touch the ground. At this time, the device can be moved by the moving wheel 4.

[0033] When the mounting plate 301 rises to the appropriate position, the locking structure needs to cooperate with the locking hole 6 to achieve locking. The dual-axis motor 309 starts, and the bidirectional screws 312 on its two output shafts rotate. Since two locking blocks 310 are symmetrically distributed on the left and right and threadedly connected to the two bidirectional screws 312 respectively, the rotation of the bidirectional screws 312 will drive the two locking blocks 310 to move towards the center and insert into the two corresponding locking holes 6 respectively, so as to lock the mounting plate 301 and the base 1.

[0034] During the process of the locking block 310 being inserted into the locking hole 6, the abutment block 504 will first contact the locking block 310. As the locking block 310 continues to move, the abutment block 504 compresses the return spring 503. The detection rod 502 moves in the through hole 505 opened inside the mounting bracket 501. The detection structure 5 can determine whether the locking block 310 is fully inserted into the locking hole 6 by the movement of the detection rod 502, thereby realizing the detection of the locking state.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
