Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, and specifically relates to a support structure for a water purifier. Background Technique

[0002] A water purifier, also known as a water purification machine or water quality purifier, is a water treatment device that deeply filters and purifies water quality according to the usage requirements of water. Generally, the water purifier mentioned usually refers to a small purifier for household use. The technical core of it is the filter membrane in the filter element device, and the main technologies come from three types: ultrafiltration membrane, RO reverse osmosis membrane, and nanofiltration membrane.

[0003] The existing water purifier is as Figure 1 shown. A support seat 2 is sleeved at the bottom of the lower shell 1 of the water purifier, and a support foot assembly 3 is arranged at the lower end of the support seat 2 for support. The support seat 2 and the lower shell 1 of the water purifier are fixed by screws passing through the center of the support foot assembly 3. Such installation also requires tools such as screwdrivers, and screwing them in one by one is time-consuming. Some are directly not fixed with screws, resulting in unstable connection between the support seat 2 and the lower shell 1 of the water purifier. When dragging the water purifier from the cabinet to the kitchen countertop, it is necessary to drag the support seat 2. Otherwise, dragging the lower shell 1 of the water purifier easily causes the support seat 2 to fall off, and then the support seat 2 needs to be reinstalled, which is rather troublesome.

Specific implementation manner

[0020] Embodiment 1, please refer to Figures 2 - 4, A support structure for a water purifier, comprising a lower shell 1 of the water purifier, a support base 2 sleeved on its lower part, and a support foot assembly 3 installed at the lower end of the support base 2. Connecting sleeves 11 are fixedly embedded at the four corners of the lower end of the lower shell 1 of the water purifier. Card slots 12 are formed on both inner side walls of the connecting sleeves 11. The support foot assembly 3 includes a rotating seat 31 and a connecting rod 32. The rotating seat 31 is fixed to the support base 2, and the connecting rod 32 is fixed to the upper end of the rotating seat 31. The connecting rod 32 is inserted into the connecting sleeve 11. A support foot 311 is inserted into the lower end of the rotating seat 31. A spring groove 315 is formed at the top end inside the rotating seat 31. A return spring 316 is fixed between the bottom of the spring groove 315 and the top end of the support foot 311. A side groove 313 is formed on one side of the inner wall of the rotating seat 31. The upper part of the side groove 313 communicates with an annular groove 314 formed on the inner wall of the rotating seat 31. A side block 312 is fixed to the side surface of the support foot 311, and the side block 312 is movably connected to the side groove 313 and the annular groove 314. A vertical piston assembly is fixed to the upper end of the support foot 311. Receiving grooves 326 are formed at both the left and right ends of the connecting rod 32. A prism-shaped clamping block 327 is slidably connected inside the receiving grooves 326. The clamping block 327 is inserted into the card slot 12. A horizontal piston assembly is fixed to the inner end of the clamping block 327. An external piston channel is provided between the horizontal piston assembly and the vertical piston assembly. The piston channel is composed of a vertical piston channel 321 and a horizontal piston channel 322. The vertical piston channel 321 is formed in the connecting rod 32. There are a pair of horizontal piston channels 322 and they are located between the receiving grooves 326. Communication ports 323 are formed between the vertical piston channel 321 and the horizontal piston channel 322, and between the horizontal piston channel 322 and the adjacent receiving groove 326. The vertical piston assembly includes a vertical piston rod 317 and a vertical piston 318. The vertical piston 318 is slidably connected inside the vertical piston channel 321. The vertical piston rod 317 is fixed to the lower end of the vertical piston 318. The lower end of the vertical piston rod 317 passes through the inside of the return spring 316 and is fixed to the upper end of the support foot 311. The horizontal piston assembly includes a horizontal piston 324 and a horizontal piston rod 325. The horizontal piston 324 is slidably connected inside the horizontal piston channel 322. The horizontal piston rod 325 is fixed to the outer end of the horizontal piston 324. The end of the horizontal piston rod 325 extends into the receiving groove 326 along the communication port 323. The end of the horizontal piston rod 325 is fixed to the clamping block 327. When the inclined surface of the clamping block 327 faces downward, the upper surface of the clamping block 327 is a plane. First, the support base 2 is sleeved on the lower part of the lower shell 1 of the water purifier, and then the connecting rod 32 is inserted into the inside of the connecting sleeve 11. In this process, a calibration line is drawn at the position directly below the card slot 12 on the lower end surface of the connecting sleeve 11, which is convenient for the clamping block 327 to correspond to the calibration line and further correspond to the card slot 12. At this time, the side block 312 is located in the side groove 313. Then, the support foot 311 is pushed, so that the side block 312 slides into the annular groove 314 along the side groove 313. At the same time, the support foot 311 drives the vertical piston rod 317 and the vertical piston 318 to slide, and the support foot 311 also compresses the return spring 316,The vertical piston 318 pushes the air inside the vertical piston passage 321 to flow into the two horizontal piston passages 322 through the communication port 323, so that the air pushes the horizontal piston 324. The horizontal piston 324 drives the horizontal piston rod 325 to slide, and the horizontal piston rod 325 drives the clamping block 327 to insert into the clamping groove 12 to limit and fix the water purifier lower shell 1 and the support seat 2. Then, the support foot 311 is rotated by 180 degrees. After the side block 312 slides in the annular groove 314 and is misaligned with the side groove 313, the support foot 311 cannot move vertically. Therefore, the support foot 311 can also normally support the entire water purifier. This not only does not require tools, but also is convenient to fix and saves time.

[0021] When it is necessary to disassemble the water purifier lower shell 1 and the support seat 2, the support foot 311 is rotated 180 degrees in reverse. After the side block 312 slides in the annular groove 314 and is located on the same vertical line as the side groove 313, the support foot 311 can be pushed back by the return spring 316. The support foot 311 drives the vertical piston 318 to pump air, so that the horizontal piston 324 drives the clamping block 327 to move out of the clamping groove 12 and be received in the storage groove 326. After that, the water purifier lower shell 1 and the support seat 2 can be separated. In addition, the water purifier lower shell 1 and the support seat 2 can also be directly pulled forcefully. Because the inclined surface of the clamping block 327 faces downward, the inner bottom surface of the clamping groove 12 contacts the inclined surface of the clamping block 327, and the clamping block 327 can be pushed into the storage groove 326, so the separation is also relatively convenient.

Connecting sleeves 11 are fixedly embedded at the four corners of the lower end of the lower shell 1 of the water purifier. Card slots 12 are formed on both inner side walls of the connecting sleeve 11. The support foot assembly 3 includes a rotating seat 31 and a connecting rod 32. The rotating seat 31 is fixed to the support base 2, the connecting rod 32 is fixed to the upper end of the rotating seat 31, the connecting rod 32 is inserted into the connecting sleeve 11, a support foot 311 is inserted into the lower end of the rotating seat 31, a spring groove 315 is formed at the top end inside the rotating seat 31, a return spring 316 is fixed between the bottom of the spring groove 315 and the top end of the support foot 311. A side groove 313 is formed on one side of the inner wall of the rotating seat 31, and the upper part of the side groove 313 communicates with an annular groove 314 formed on the inner wall of the rotating seat 31. A side block 312 is fixed to the side of the support foot 311, and the side block 312 is movably connected to the side groove 313 and the annular groove 314. A vertical piston assembly is fixed to the upper end of the support foot 311. Receiving grooves 326 are formed at both the left and right ends of the connecting rod 32. A prism-shaped clamping block 327 is slidably connected inside the receiving groove 326. The clamping block 327 is inserted into the card slot 12. A horizontal piston assembly is fixed to the inner end of the clamping block 327. An external piston channel is provided between the horizontal piston assembly and the vertical piston assembly. The piston channel is composed of a vertical piston channel 321 and a horizontal piston channel 322. The vertical piston channel 321 is formed in the connecting rod 32. There are a pair of horizontal piston channels 322 and they are located between the receiving grooves 326. Communication ports 323 are formed between the vertical piston channel 321 and the horizontal piston channel 322, and between the horizontal piston channel 322 and the adjacent receiving groove 326. The vertical piston assembly includes a vertical piston rod 317 and a vertical piston 318. The vertical piston 318 is slidably connected inside the vertical piston channel 321. The vertical piston rod 317 is fixed to the lower end of the vertical piston 318. The lower end of the vertical piston rod 317 passes through the inside of the return spring 316 and is fixed to the upper end of the support foot 311. The horizontal piston assembly includes a horizontal piston 324 and a horizontal piston rod 325. The horizontal piston 324 is slidably connected inside the horizontal piston channel 322. The horizontal piston rod 325 is fixed to the outer end of the horizontal piston 324. The end of the horizontal piston rod 325 extends into the receiving groove 326 along the communication port 323. The end of the horizontal piston rod 325 is fixed to the clamping block 327. When the inclined surface of the clamping block 327 faces upward, the lower end surface of the clamping block 327 is a flat surface. The horizontal piston rod 325 is a spring telescopic rod, which is composed of a sleeve, a sliding rod and a spring. The first end of the sliding rod is slidably connected inside the end of the sleeve. The first end of the sleeve is fixed to the horizontal piston 324. The end of the sliding rod is fixed to the clamping block 327. The spring is connected between the inner end of the clamping block 327 and the end of the sleeve. In this way, the support foot 311 can be pushed first, so that the side block 312 slides into the annular groove 314 along the side groove 313. At the same time, the support foot 311 drives the vertical piston rod 317 and the vertical piston 318 to slide, and the support foot 311 also compresses the return spring 316.The vertical piston 318 pushes the air inside the vertical piston passage 321 to flow into the two horizontal piston passages 322 along the communication port 323, so that the air pushes the horizontal piston 324. The horizontal piston 324 drives the horizontal piston rod 325 to slide. The horizontal piston rod 325 drives the latch 327 to move out of the receiving groove 326. Then, the support leg 311 is rotated by 180 degrees. After the side block 312 slides inside the annular groove 314 and is misaligned with the side groove 313, the support leg 311 can no longer move vertically. Then, the support base 2 is placed on the ground. After that, the connecting sleeve 11 under the water purifier lower shell 1 is inserted corresponding to the connecting rod 32. At this time, the connecting sleeve 11 contacts the upper inclined surface of the latch 327, and the latch 327 can be pushed into the receiving groove 326. At this time, the sliding rod slides into the sleeve, and the latch 327 compresses the spring. In this way, the horizontal piston 324 does not move, and the latch 327 is also received into the receiving groove 326 until the latch 327 corresponds to the card slot 12. The spring resets and pushes the latch 327 to be inserted into the card slot 12 to limit and fix the water purifier lower shell 1 and the support base 2. Therefore, the support leg 311 can also normally support the entire water purifier. This not only does not require tools, but also is convenient to fix and saves time;

[0023] When it is necessary to disassemble the water purifier lower shell 1 and the support base 2, the support leg 311 is rotated 180 degrees in reverse. After the side block 312 slides inside the annular groove 314 and is located on the same vertical line as the side groove 313, the support leg 311 can be pushed back by the return spring 316. The support leg 311 drives the vertical piston 318 to pump air, so that the horizontal piston 324 drives the latch 327 to move out of the card slot 12 and be received into the receiving groove 326. After that, the water purifier lower shell 1 and the support base 2 can be separated, and the separation is also relatively convenient.
