The filter cylinder and the filter cover are connected, and a filter element is installed between the filter cylinder and the filter cover. The bottom wall of the inner shell of the filter cover is provided with a raised cross groove reinforcing rib.

[0004] Existing water purifier filter cartridges are difficult to replace quickly due to their threaded installation and limited internal space. Therefore, a device is needed to address this issue. Utility Model Content

[0005] The purpose of this invention is to provide a water purifier filter box that is easy to disassemble, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water purifier filter box that is easy to disassemble, comprising a guiding device, the guiding device comprising a vertical rod, a filter cartridge shell, an auxiliary sleeve, a support base, and a bottom shell, the auxiliary sleeve and the support base being fixedly installed inside the top and bottom of the bottom shell, the filter cartridge shell being equidistantly slidably inserted into the auxiliary sleeve and the support base, the vertical rod being symmetrically fixedly installed at the top of both ends of the bottom shell, the filter cartridge shell being slidably sleeved on the outer ring of the guiding device, and a positioning device being fixedly installed at the front end of the filter cartridge shell.

[0007] Preferably, the positioning device includes a synchronizing rod, a limiting rod, a displacement slider, a supporting cavity, a synchronizing frame, and a return spring. The displacement slider is slidably inserted into the inside of the supporting cavity. The return spring is fixedly installed between the supporting cavity and the displacement slider. The limiting rod is fixedly installed at the end of the displacement slider away from the return spring. The synchronizing rod is fixedly installed between the two displacement sliders. The synchronizing frame is fixedly installed between the two synchronizing rods.

[0008] Preferably, limiting sleeves are fixedly installed at the top of both ends of the filter housing, and connectors are fixedly installed at equal intervals inside the filter housing.

[0009] Preferably, the support cavity is symmetrically fixedly installed at both ends of the filter housing, and the support cavity is located above the limiting sleeve, with the vertical rod slidably inserted into the inside of the limiting sleeve.

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-4 The present invention provides an embodiment of a water purifier filter box that is easy to disassemble, comprising a guide device 1. The guide device 1 includes a vertical rod 4, a filter cartridge shell 5, an auxiliary sleeve 6, a support base 7, and a bottom shell 8. The auxiliary sleeve 6 and the support base 7 are fixedly installed inside the top and bottom of the bottom shell 8. The filter cartridge shell 5 is equidistantly slidably inserted into the auxiliary sleeve 6 and the support base 7. The vertical rod 4 is symmetrically fixedly installed at the top of both ends of the bottom shell 8. A filter cartridge shell 3 is slidably sleeved on the outer ring of the guide device 1. A positioning device 2 is fixedly installed at the front end of the filter cartridge shell 3.

[0021] The positioning device 2 includes a synchronizing rod 9, a limiting rod 10, a displacement slider 11, a supporting cavity 12, a synchronizing frame 13, and a return spring 14. The displacement slider 11 is slidably inserted into the inside of the supporting cavity 12. The return spring 14 is fixedly installed between the supporting cavity 12 and the displacement slider 11. The limiting rod 10 is fixedly installed at the end of the displacement slider 11 away from the return spring 14. The synchronizing rod 9 is fixedly installed between the two displacement sliders 11. The synchronizing frame 13 is fixedly installed between the two synchronizing rods 9. The synchronizing rods 9 are connected to the displacement slider 11 and the synchronizing frame 13 respectively, so that when the synchronizing frame 13 is displaced, it can drive the displacement slider 11 to move.

[0022] Limiting brackets 15 are fixedly installed at the top of both ends of the filter housing 3. Connectors 16 are fixedly installed at equal intervals inside the filter housing 3. Water outlet pipes and water inlet pipes are installed through the top and side ends of the filter housing 3, so that the water inlet pipes and water outlet pipes can be easily matched with the connectors 16 and the filter housing 5.

[0023] The support cavity 12 is symmetrically fixed at both ends of the filter housing 3, and the support cavity 12 is located above the limiting sleeve 15. The vertical rod 4 is slidably inserted into the inside of the limiting sleeve 15 to ensure that the bottom housing 8 moves up and down in a straight line.

[0024] The limiting sleeve 15 has a vertical circular hole inside, and the vertical rod 4 has a horizontal circular hole inside, so that the limiting rod 10 can be connected with the vertical rod 4.

[0025] The support cavity 12 has a movable groove inside the side end near the synchronizing rod 9, and the displacement slider 11 is located inside the sliding groove to ensure that the limiting rod 10 moves in a straight line.

[0026] Working principle: During use, the water outlet pipe at the top of the filter housing 3 is connected to the household water pipe, and the water inlet pipe at the top side of the filter housing 3 is connected to the external tap water pipe, allowing water to pass through the interior of the three filter cartridge housings 5. This intercepts and filters impurities and bacteria from the tap water, making the filtered water usable. When the filter cartridge housing 5 needs to be replaced, the user can pull the synchronization bracket 13 forward with one hand, causing the displacement slider 11 to move the limiting rod 10 out of the interior of the vertical rod 4, thereby releasing the vertical rod 4. At the same time, the user... The other hand can be placed on the bottom of the bottom housing 8, so that the vertical rod 4 can slide downwards and fall off completely when it is no longer restrained by the limiting rod 10. Then, when the bottom housing 8 is separated from the filter housing 3, the filter element housing 5 can be pulled vertically upwards from the inside of the bottom housing 8 to remove the filter element housing 5. Then, the new filter element housing 5 is moved to the top of the auxiliary sleeve 6 and inserted into the support base 7, so that the filter element housing 5 can be installed inside the bottom housing 8. Then, the bottom housing 8 is moved to the bottom of the filter housing 3 until... The vertical rod 4 is vertically aligned with the limiting sleeve 15. Then, the bottom outer shell 8 is moved upward so that the vertical rod 4 can be inserted into the round hole inside the limiting sleeve 15. This allows the bottom outer shell 8 to move upward in a straight line. Subsequently, when the top of the bottom outer shell 8 is in contact with the bottom of the filter housing 3, the horizontal round hole inside the vertical rod 4 can be horizontally aligned with the limiting rod 10. Furthermore, because a sealing gasket is fixedly installed on the top of the filter housing 5, when the bottom outer shell 8 moves upward to be in contact with the filter housing 3, the sealing gasket can be squeezed and tightly fitted to the joint 16 to prevent the filter element from being exposed to the outside. If leakage occurs between the shell 5 and the connector 16, the synchronous frame 13 can be released. The elasticity of the return spring 14 will drive the displacement slider 11 to move and reset quickly, so that the limiting rod 10 can be inserted into the horizontal circular hole inside the vertical rod 4. This can prevent the bottom shell 8 from falling off, thus completing the quick installation of the filter element shell 5. At the same time, the displacement slider 11 moves in the movable groove inside the side of the support cavity 12, which can support the displacement slider 11 and the limiting rod 10 to move in a straight line, improving the docking accuracy of the limiting rod 10 and the vertical rod 4.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
