It is well known that a water purifier can effectively filter out harmful impurities such as rust, sand, bacteria and heavy metals in tap water through various filter elements. The various components contained in the water purifier are fixed on the bracket by threads. When installing a booster pump, the water pipe connected to the pump needs to be shorter. If it is too long, the housing will be knocked by the vibration of the pump. Each filter element on the bracket filters different impurities, and thus has different usage cycles and needs to be replaced regularly. When replacing, the filter element fixed by threads is removed from the bracket and a new filter element is replaced.

[0043] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0044] See also Figure 1-21 , water treatment equipment, used to solve the problem that the filter elements on the water purifier are directly installed through threaded fasteners. Because each filter element filters different impurities during use and the corresponding use cycle is also different, the vibration caused by the booster pump during operation may cause the threaded fasteners to gradually loosen, causing a collision between the filter element and the bracket, affecting the normal use of the water purifier.

[0045] As a further technical solution proposed by the present invention, it includes a bracket 1 and a driving unit arranged on the bracket 1, and also includes: a mounting plate 601, which is vertically slidably arranged on the bracket 1, a turntable 7 is rotatably arranged on the mounting plate 601, a clamping column 704 is arranged on the inner wall of the turntable 7, and a spiral groove 702 is opened on the top of the turntable 7; a filter element group 5, which is located on the turntable 7, and a clamping seat 503 is arranged on the circumference of the filter element group 5; a spring limiting mechanism, which includes a limiting column 803, and the limiting column 803 is connected to the spiral groove 702;During installation, the filter element group 5 moves upward to squeeze the turntable 7. Under the cooperation of the limiting column 803 and the spiral groove 702, the turntable 7 is forced to rotate. The rotation of the turntable 7 causes the clamping column 704 to move in the circumferential direction of the filter element group 5 and be clamped in the clamping seat 503. Specifically, the filter element group 5 includes three different filter elements. The three filter elements are placed inside the shell, and the impurities filtered by them are also different. There is a filter element in the filter element group 5 that is connected to the booster pump 2. The filter element group 5 and other drive units are installed on a movable plate during installation. It is known that the greater the mass, the greater the inertia, and the greater the energy required for vibration. Therefore, when the booster pump in the drive unit vibrates during operation, the amplitude of its vibration is reduced by weight, which correspondingly reduces the noise caused by the vibration. The filter element on the device is installed by a clamping mechanism, which weakens or even avoids the loosening of the threaded fasteners in the prior art. During installation, a through groove corresponding to the number of filter elements in the filter element group is opened on the installed mounting plate 601, and the center of the turntable 7 corresponds to the center of the through groove and is rotatably arranged on the mounting plate 601. The through groove is convenient for the filter element on the filter element group 5 to pass through the mounting plate 601 and be placed in the turntable 7. The turntable 7 in this embodiment is a compound movement of linear motion plus rotational motion. First, when the top of the filter element group 5 is located in the turntable 7, the filter element group 5 is pushed upward at this time, so that the mounting plate 601 is forced to move synchronously. In the upward stroke, the turntable 7 on the mounting plate 601 slides in the spiral groove 702 when the limit column 803 The rotating disk 7 is locked in the state where the filter element group 5 is in the same state. The locking column 704 inside the rotating disk 7 will move in the circumferential direction of the filter element group 5 as the rotating disk 7 rotates and finally locks in the locking seat 503 at the end of the stroke, so that the filter element group 5 is installed on the rotating disk 7. The filter element group 5 is placed in the rotating disk 7 and squeezed upward to achieve quick installation of the filter element. It should be noted that the stroke of the spring limiting mechanism being locked in the spiral groove 702 and the locking column 704 inside the rotating disk 7 The stroke of the column 704 rotating and engaging with the holder 503 on the filter element group 5 can also be determined by a person skilled in the art through logical analysis and reasoning or limited experiments to ensure that when the limiting column on the spring limiting mechanism is engaged with the spiral groove 702, the holder 503 on the filter element is also engaged with the column 704. It is known that the use cycles of the filter elements on the filter element group 5 are different. When one of the cycles is over, it needs to be replaced. First, because the turntable 7 is locked by the spring limiting mechanism, it is in a fixed state, and the filter element is located in the turntable 7 and has space for rotation, so that when the turntable 7 is in a locked state, the operator only needs to rotate the filter element to be replaced to rotate it in the turntable 7. Figure 7 For reference, at this time, rotating the filter element clockwise can separate the holder 503 and the column 704. After separation, vertically remove the filter element from the inside of the turntable 7, then place the new filter element under the turntable 7 and adjust it to the state when the old filter element was taken out, then move the new filter element upward and place it in the turntable 7 and rotate it counterclockwise so that the holder 503 is engaged with the column 704 again, and the new filter element is installed on the turntable 7.

[0046] In another embodiment provided by the present invention, a carrying plate 6 is provided on the bracket 1, and an elastic reset member is provided between the carrying plate 6 and the bracket 1, a rotating column 701 is provided on the top of the turntable 7, a spiral groove 702 is opened on the rotating column 701, and a clamping hole 703 is opened on the spiral groove 702, which is used to clamp with the limiting column 803 to lock the carrying plate 601. Further, the carrying plate 601 is located on the carrying plate 6, and a guide groove 102 is relatively opened on the bracket 1. The carrying plate 6 is vertically slidably arranged in the guide groove 102, and at least four elastic reset members are provided between the carrying plate 6 and the bracket 1. The elastic reset member is a first spring 101, which is used to play a certain vibration reduction effect under the vibration of the booster pump 2 when working after each driving element is installed on the carrying plate 6. When the limiting column 803 slides along the spiral groove 702 to the clamping hole 703, it is clamped into the clamping hole 703 under the elastic force of the spring limiting mechanism.

[0047] In another embodiment of the present invention, a limiting disk 705 is provided at the center of the inner wall of the turntable 7, which is used to abut against the positioning groove 504 provided on the filter element group 5. Furthermore, the limiting disk 705 rotatably provided at the center of the turntable 7 is used for when the filter element group 5 is placed in the turntable 7, the filter element group 5 is in a state of being squeezed and raised, and the turntable 7 is still in a rotating state during the rising process. At this time, the top of the filter element group 5 will rub against the inner wall of the turntable 7, and under the action of the rotatably provided limiting disk 705, the positioning groove 504 provided on the top of the filter element group 5 can be adapted to the limiting disk 705, which enables the filter element group 5 to avoid friction with the inner wall when squeezing the turntable 7. At the same time, because the diameter of the turntable 7 is larger than the diameter of the top of the filter element, the limiting disk 705 cooperates with the positioning groove 504 to also play a role of pre-positioning, so that the clamping column 704 in the turntable 7 can be accurately clamped into the clamping seat 503 on the filter element group 5 as the turntable 7 rotates.

[0048] In another embodiment provided by the present invention, preferably, the filter element group 5 is provided with a connected annular groove 502 and a limiting groove 501 on one side of the holder 503. When the carrying plate 601 is in an ascending state, the clamping column 704 is located in the limiting groove 501. When the turntable 7 is in a rotating state, the clamping column 704 is located in the annular groove 502. Further, the clamping column 704 in the turntable 7 includes a positioning block and an arc-shaped rod connected to the positioning block. Figure 5For reference, the limiting groove 501 is used to move the top of the filter element group 5 toward the turntable 7. The positioning block on the turntable 7 first contacts the limiting groove 501 on the filter element group 5, so that the positioning block is located in the limiting groove 501, playing a first pre-positioning role. When the positioning block continues to rise with the filter element group 5 so that it moves from the limiting groove 501 to the annular groove 502, the positioning groove 504 on the filter element group 5 is connected to the limiting plate 705, playing a second positioning role. At this time, the filter element group 5 continues to rise and will conflict with the limiting plate 705, causing the turntable 7 to start rotating. During this process, the positioning block slides in the annular groove 502, and the annular groove 502 plays a third positioning role and cooperates with the limiting plate 705 so that the clamping column 704 can be accurately clamped into the clamping seat 503.

[0049] In another embodiment provided by the present invention, preferably, the spring limiting mechanism includes a connecting seat 8, a connecting frame 801, a second spring 802 and a limiting column 803 which are connected in sequence. The connecting seat 8 is arranged on the supporting plate 6, and one end of the limiting column 803 is located in the spiral groove 702. When the rotation stroke of the turntable 7 ends, the limiting column 803 is driven by the elastic force of the second spring 802 to be inserted into the clamping hole 703. When it is necessary to remove the limiting column 803 on the spring limiting mechanism from the clamping hole 703, the limiting column 803 is moved toward the side of the connecting frame 801 to compress the second spring 802. At this time, the turntable 7 is in an active state and can be reset during the descending stroke of the supporting plate 601.

[0050] In another embodiment provided by the present invention, it also includes a base 9, on which a reverse osmosis membrane filter element 4 is arranged, a support seat is relatively arranged on the base 9, a bending rod 901 is relatively arranged on the support seat, the bending rod 901 is movably connected to a clamp 903 through a third spring 902, and a post-activated carbon filter element 3 is arranged on the clamp 903. Further, because all components are placed on the supporting plate 6, the post-activated carbon filter element 3 installed on the top of the reverse osmosis membrane filter element 4 will be affected by the slight vibration caused by the operation of the booster pump 2. Under the influence of the vibration, the clamp 903 connected between the reverse osmosis membrane filter element 4 and the post-activated carbon filter element 3 will be affected by the weight of the post-activated carbon filter element 3 and the vibration of the supporting plate 6. Figure 1 For reference, in some embodiments, the clamp 903 may be tilted on the reverse osmosis membrane filter element 4 so that the post-activated carbon filter element 3 collides with the subsequently installed housing. After the collision contact, under the continuous vibration of the supporting plate 6, the post-activated carbon filter element 3 will repeatedly collide with the housing, causing noise and suffering certain damage. In other embodiments, the tilted clamp 903 directly makes the post-activated carbon filter element 3 contact with the booster pump 2. In order to avoid this situation from happening, the bending rod 901 cooperates with the third spring 902 to Fig.10For reference, when the clip 903 is offset to the right, the clip 903 contacts the two third springs 902 on the right, compressing them, and the two third springs 902 on the left are stretched simultaneously, and the clip 903 is prevented from tilting under the action of the third springs 902. It should be noted that the elastic force of the third spring 902 is greater than the weight of the clip 903 and the post-activated carbon filter 3; the clip 903 is slidably installed with the bending rod 901, and the center of the bending rod 901 is at the same position as the center of the clip 903.

[0051] In another embodiment provided by the present invention, preferably, a placement groove 603 is opened on the supporting plate 6, and the placement groove 603 is used to limit the booster pump 2. A rubber pad is arranged between the placement groove 603 and the booster pump 2 of the water treatment equipment. The rubber pad in the placement groove 603 is used to contact the booster pump 2, so that the booster pump 2 and the placement groove 603 fit more stably.

[0052] In another embodiment provided by the present invention, a self-locking anti-vibration mechanism is also included, which includes four connecting rods 604, two sliding plates 605, four clamping rods 606 and two wedge blocks 203. A clamping groove 201 is provided on the base of the booster pump 2, and a slope 202 is provided on the clamping groove 201. The wedge block 203 is arranged on the side of the booster pump 2 away from the clamping groove 201. The four connecting rods 604 are symmetrically hinged to the two sliding plates 605 in pairs, and the other ends thereof are hinged to the carrying plate 601. The two sliding plates 605 are symmetrically slidably arranged on the carrying plate 6 The two sliding plates 605 include a plate body and an abutment rod connected to the plate body. When the abutment rod contacts the inclined surface 202, the booster pump 2 is pressed down by the placement groove 603. When the sliding stroke of the two sliding plates 605 ends, the abutment rod is located in the clamping groove 201 so that the clamping rod 606 and the wedge block 203 are wedge-matched. Further, the booster pump 2 is installed in the placement groove 603. First, the booster pump 2 is placed in the placement groove 603. The bearing plate 6 is provided with slide grooves 602 on both sides of the placement groove 603. The two sliding plates 605 are slidably installed in the slide grooves 602 respectively. Fig.18 For reference, the sliding plates 605 slidably installed on both sides of the booster pump 2 are hinged to the carrying plate 601 through the connecting rod 604, and then when the carrying plate 601 rises, the connecting rod 604 will be linked to push the sliding plate 605 to slide in the slide groove 602, and when the carrying plate 601 is in a locked state, that is, the rotation stroke of the turntable 7 is completed, the abutment rod on the sliding plate 605 will be clamped in the clamping groove 201, and the booster pump 2 will be fixed in the placement groove 603. It should be noted that before the abutment rod is clamped in the clamping groove 201, Fig.12For reference, during the sliding stroke of the sliding plate 605, the abutment rod will first come into contact with the inclined portion 202 on the base of the booster pump 2, i.e., a wedge-shaped fit. During this fit, the booster pump 2 will be pressed downward into the placement groove 603 by force, thereby making the booster pump 2 and the rubber pad squeeze and fit better with the placement groove 603. As the sliding stroke of the sliding plate 605 continues, the abutment rod will enter the clamping groove 201 from the inclined portion 202 until the stroke ends. When the sliding plate 605 ends, the clamping rod 606 on the abutment rod will come into contact with the wedge-shaped block 203 on the outside of the base of the booster pump 2, so as to prevent the booster pump 2 from sliding. Fig.13 For reference, in this state, when the booster pump 2 vibrates during operation, when it vibrates to the left, the two clamping rods 606 on the right further interfere with the wedge block 203. Similarly, when it vibrates to the right, they interfere again. In essence, a self-locking effect is achieved when the booster pump 2 vibrates, and it will only become tighter and tighter with the vibration, making the booster pump 2 more stable after installation. Compared with the installation method using threaded fasteners, this method effectively avoids the loosening of threaded fasteners in the prior art.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
