[0002] The water purifier filter cartridge installation assembly adopts an innovative mechanical quick-installation structure design, achieving rapid installation and a high-sealing connection of the filter cartridge through a precisely matched snap-fit ​​and limiting system. The core of the assembly consists of three main modules: the filter cylinder, the filter cartridge, and the cover plate. The hollow limiting plate and limiting block on the filter cylinder form the first-level guiding positioning, ensuring precise alignment between the annular groove and the filter cartridge. Under the elastic force of the pre-compressed limiting spring, the trapezoidal locking plate automatically snaps into the limiting groove, generating a locking force of 12-15N, so that the interface meets industrial-grade sealing standards.

[0003] During the installation of water purifier filter cartridges, most cartridges require screws for fixing, which not only wastes installation time but also poses a risk of corrosion, thus reducing installation and disassembly efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a water purifier filter cartridge installation assembly to solve at least one of the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water purifier filter cartridge mounting assembly, including a mounting box, and further comprising:

[0006] A limiting mechanism is provided inside the mounting box. The limiting mechanism includes a funnel cylinder disposed inside the mounting box. The limiting mechanism is used to limit the funnel cylinder after it is installed into the mounting box, so as to ensure the stability and accuracy of the funnel cylinder and enhance the installation efficiency.

[0007] A sealing mechanism is provided on the mounting box. The sealing mechanism includes a cover plate provided on the mounting box. The sealing mechanism is used to ensure that the mounting box and the cover plate can be stably connected when the cover plate is connected to the mounting box, so as to maintain a stable sealing state of the device.

[0008] Preferably, the limiting mechanism includes a filter cylinder that is slidably installed in the installation box, a filter element that is fixedly installed in the filter cylinder, an annular groove that is fixedly sleeved on the outer wall of the filter cylinder, and an annular block that is fixedly installed on the bottom inner wall of the installation box, the annular groove and the annular block being adapted to each other.

[0009] Preferably, two limiting blocks are fixedly installed on the bottom inner wall of the mounting box, and two hollow limiting plates are fixedly installed on the outer wall of the funnel, with the two hollow limiting plates slidably connected to the two limiting blocks respectively.

[0010] Preferably, limit springs are fixedly installed on the inner walls of the two hollow limiting plates that are close to each other, and trapezoidal clamping plates are fixedly installed on the ends of the two limiting springs that are far apart from each other.

[0011] Preferably, a limiting groove is formed on the inner wall of the side of the two limiting blocks that are close to each other, and the ends of the two trapezoidal plates that are far apart from each other slide into the two limiting grooves respectively.

[0012] Preferably, the top of each of the two hollow limiting plates is provided with a strip groove, and the top of each of the two trapezoidal plates is fixedly installed with a sliding block, the top of each of the two sliding blocks slidingly extending out of the two strip grooves.

[0013] Preferably, the sealing mechanism includes a cover plate slidably disposed above the mounting box, an inlet pipe being installed through the cover plate, the bottom end of the inlet pipe extending into the leaking cylinder and fitting into the leaking cylinder, and a rectangular ring plate being fixedly installed at the bottom of the cover plate, the bottom end of the rectangular ring plate extending slidably into the mounting box.

[0014] Preferably, an inverted plate is fixedly installed on the left and right sides of the mounting box, and a rectangular sliding block slides through each of the two inverted plates.

The ends of the two return springs that are close to each other are fixedly connected to the mounting box, and the ends of the two return springs that are far apart from each other are fixedly connected to the two inverted plates.

[0015] The beneficial effects of this utility model are as follows:

[0016] In this utility model:

[0017] 1. Insert the hollow limiting plate on the filter cylinder into the limiting block. Under the limiting action of the limiting block, the filter cylinder drives the annular groove to accurately engage with the filter element. As the hollow limiting plate descends, it will drive the trapezoidal clamping plate to descend synchronously. After the trapezoidal clamping plate contacts the limiting groove, due to the compression of the limiting spring, it will be directly ejected into the limiting groove under the elastic force of the limiting spring. At this time, the annular groove and the filter element will fit tightly, improving the sealing of the device and preventing water from overflowing. The filter cylinder can also be installed quickly at the same time.

When the cover plate descends, it will drive the water inlet pipe to descend synchronously. When the groove on the rectangular ring plate contacts the rectangular sliding block, the rectangular sliding block will be locked into the rectangular ring plate under the elastic force of the return spring, thus completing the connection between the mounting box and the cover plate. At this time, the rectangular ring plate will also extend into the leaking cylinder to ensure that water will not leak. The connection between the mounting box and the cover plate prevents dust from entering the device and contaminating the water. Attached Figure Description

[0025] 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.

[0026] This utility model provides, for example Figure 1-5The water purifier filter cartridge installation assembly shown includes an installation box 1 and further includes: a limiting mechanism, which is disposed within the installation box 1 and includes a filter cartridge 101 disposed within the installation box 1. The limiting mechanism is used to limit the filter cartridge 101 after it is installed into the installation box 1, ensuring the stability and accuracy of the filter cartridge 101 and enhancing installation efficiency; and a sealing mechanism, which is disposed on the installation box 1 and includes a cover plate 2 disposed on the installation box 1. The sealing mechanism is used to ensure that the installation box 1 and the cover plate 2 can be stably connected when the cover plate 2 is connected to the installation box 1, thereby maintaining a stable sealing state of the device. The limiting mechanism includes a filter cartridge 101 slidably installed within the installation box 1. A filter cartridge 102 is fixedly installed inside the filter cartridge 101. An annular groove 103 is fixedly sleeved on the outer wall of the filter cartridge 101. An annular block 104 is fixedly installed on the inner bottom wall of the installation box 1, and the annular groove 103 and the annular block 104 are adapted to each other. Two limiting blocks 105 are fixedly installed on the bottom inner wall of the mounting box 1, and two hollow limiting plates 106 are fixedly installed on the outer wall of the funnel cylinder 101. The two hollow limiting plates 106 are slidably connected to the two limiting blocks 105 respectively. Limiting springs 107 are fixedly installed on the inner walls of the two hollow limiting plates 106 on the side closest to each other, and trapezoidal clamping plates 108 are fixedly installed on the ends of the two limiting springs 107 that are far apart from each other. Limiting grooves 109 are formed on the inner walls of the two limiting blocks 105 on the side closest to each other, and the ends of the two trapezoidal clamping plates 108 that are far apart from each other slide into the two limiting grooves 109 respectively. Strip grooves 110 are formed on the top of the two hollow limiting plates 106 respectively, and sliding blocks 111 are fixedly installed on the top of the two trapezoidal clamping plates 108 respectively. The tops of the two sliding blocks 111 slide out of the two strip grooves 110 respectively.

[0027] Insert the hollow limiting plate 106 on the filter cylinder 101 into the limiting block 105. Under the limiting action of the limiting block 105, the filter cylinder 101 drives the annular groove 103 to accurately engage with the filter element 102. As the hollow limiting plate 106 descends, it will drive the trapezoidal clamping plate 108 to descend synchronously. After the trapezoidal clamping plate 108 contacts the limiting groove 109, due to the compression of the limiting spring 107, the trapezoidal clamping plate 108 will directly spring into the limiting groove 109 under the elastic force of the limiting spring 107. At this time, the annular groove 103 and the filter element 102 will fit tightly, improving the sealing of the device and preventing water from overflowing. The filter cylinder 101 can also be quickly installed at the same time.

[0028] The sealing mechanism includes a cover plate 2 slidably mounted above the mounting box 1. A water inlet pipe 201 is installed through the cover plate 2, and the bottom end of the water inlet pipe 201 extends into the leaking cylinder 101 and is adapted to the leaking cylinder 101. A rectangular ring plate 202 is fixedly mounted at the bottom of the cover plate 2, and the bottom end of the rectangular ring plate 202 slides into the mounting box 1. C-shaped plates 203 are fixedly mounted on the left and right sides of the mounting box 1, respectively. Rectangular sliding blocks 204 are slidably mounted through the two C-shaped plates 203. The ends of the two rectangular sliding blocks 204 that are close to each other slide into the rectangular ring plate 202. The ends of the two rectangular sliding blocks 204 that are close to each other are trapezoidal. A return spring 205 is sleeved on the two rectangular sliding blocks 204. The ends of the two return springs 205 that are close to each other are fixedly connected to the mounting box 1, and the ends of the two return springs 205 that are far apart from each other are fixedly connected to the two C-shaped plates 203, respectively.

[0029] Then, cover plate 2 is placed on mounting box 1, and rectangular ring plate 202 is aligned with the groove on mounting box 1 and slid in for connection. When cover plate 2 descends, it will drive water inlet pipe 201 to descend synchronously. When the groove on rectangular ring plate 202 contacts rectangular sliding block 204, rectangular sliding block 204 will be locked into rectangular ring plate 202 under the elastic force of return spring 205, thus completing the connection between mounting box 1 and cover plate 2. At this time, rectangular ring plate 202 will also extend into the leaking cylinder 101 to ensure that water will not leak. The connection between mounting box 1 and cover plate 2 prevents dust from entering the device and contaminating the water.

[0030] The working principle of the water purifier filter cartridge installation assembly provided by this utility model is as follows:

[0031] Insert the hollow limiting plate 106 on the filter cylinder 101 into the limiting block 105. Under the limiting action of the limiting block 105, the filter cylinder 101 drives the annular groove 103 to accurately engage with the filter element 102. As the hollow limiting plate 106 descends, it will drive the trapezoidal clamping plate 108 to descend synchronously. After the trapezoidal clamping plate 108 contacts the limiting groove 109, due to the compression of the limiting spring 107, the trapezoidal clamping plate 108 will directly spring into the limiting groove 109 under the elastic force of the limiting spring 107. At this time, the annular groove 103 and the filter element 102 will fit tightly, improving the sealing of the device and preventing water from overflowing. The filter cylinder 101 can also be quickly installed at the same time.

[0032] Then, cover plate 2 is placed on mounting box 1, and rectangular ring plate 202 is aligned with the groove on mounting box 1 and slid in for connection. When cover plate 2 descends, it will drive water inlet pipe 201 to descend synchronously. When the groove on rectangular ring plate 202 contacts rectangular sliding block 204, rectangular sliding block 204 will be locked into rectangular ring plate 202 under the elastic force of return spring 205, thus completing the connection between mounting box 1 and cover plate 2. At this time, rectangular ring plate 202 will also extend into the leaking cylinder 101 to ensure that water will not leak. The connection between mounting box 1 and cover plate 2 prevents dust from entering the device and contaminating the water.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
