[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Depend on Figure 1-4 The utility model provides a quick-disassembly structure of the filter housing. The top wall of the filter housing 100 is movably connected with an upper cover 101, and the filter housing 100 is conveniently closed by the upper cover 101. The bottom wall of the upper cover 101 is fixedly connected with a clamping frame 102, and the clamping frame 102 is convenient for limiting and fixing the upper cover 101. The left and right side walls of the clamping frame 102 are provided with clamping grooves, and the left and right side walls of the inner cavity of the filter housing 100 are provided with grooves. The opposite side walls of the inner cavities of the two groups of grooves are fixedly connected with clamping springs 103, and the clamping springs 103 are convenient for pushing the clamping block 104 to move. The two groups of clamping The opposite side walls of the spring 103 are fixedly connected with a clamping block 104, which is convenient for clamping into the inner cavity of the clamping groove to limit the installation of the clamping frame 102. The opposite side walls of the two groups of clamping blocks 104 are inclined, which is convenient for pushing the clamping blocks 104 to move. The left and right side walls of the clamping frame 102 are provided with sliding grooves, which are convenient for limiting and guiding the movement of the quick-release frame 105. The top wall of the filter housing 100 is slidably connected with the quick-release frame 105, which is convenient for pushing the clamping block 104 to move and facilitate disassembly. The quick-release frame 105 is located in the inner cavity of the sliding groove.

[0022] In this embodiment: the upper cover 101 is taken up to drive the clamping frame 102 to move, the clamping frame 102 is inserted into the groove, and the clamping frame 102 pushes the clamping block 104 to move. When the clamping block 104 is located at the clamping groove, the clamping spring 103 pushes the clamping block 104 to move, so that the clamping block 104 is clamped to the inner cavity of the clamping groove, and the clamping frame 102 is limited by the clamping block 104, and the upper cover 101 is limited and fixed by the clamping frame 102. When disassembly is required, the quick-release frame 105 is pressed to move the clamping block 104, and the clamping block 104 is pushed to release the limit on the clamping frame 102, so that the upper cover 101 can be disassembled and removed, which is convenient for subsequent replacement and maintenance of the filter element. The device can be easily disassembled, and the filter can be replaced without the help of tools, which is conducive to improving work efficiency.

[0023] It should be noted that the groove is T-shaped, and the groove is used to limit and guide the movement of the clamping frame 102 to prevent the clamping frame 102 from deflecting, which is beneficial to limiting the upper cover 101. The outer wall of the filter housing 100 is provided with a liquid inlet, and the bottom wall of the filter housing 100 is provided with a liquid outlet. The filter element is screwed to the bottom wall of the inner cavity of the filter housing 100 by screwing, and the filtered liquid is discharged through the liquid outlet.

[0024] The bottom wall of the inner cavity of the filter housing 100 is fixedly connected with a pop-up spring 106, which facilitates pushing the pop-up ring 107 to move. The top wall of the pop-up spring 106 is fixedly connected with a pop-up ring 107, which facilitates pushing the clamping frame 102 to move upward and pop out. The pop-up ring 107 is located on the bottom wall of the clamping frame 102.

[0025] In this embodiment: during disassembly, the elastic force of the pop-up spring 106 facilitates the pop-up ring 107 to move, and the pop-up ring 107 pushes the card frame 102 to move, so that the card frame 102 can be popped outward, which is convenient for disassembly work and is conducive to taking out the card frame 102.

[0026] A sealing ring 108 is fixedly connected to the bottom wall of the upper cover 101 , and the sealing ring 108 is used to seal the joint. The sealing ring 108 is made of rubber material and is located on the top wall of the filter housing 100 .

[0027] In this embodiment, when pressed and locked, the sealing ring 108 can be slightly deformed to fit the joint between the upper cover 101 and the filter housing 100, which can improve the sealing performance of the device, avoid leakage during filtration, and facilitate filtration operations.

[0028] A lifting spring 109 is fixedly connected to the top wall of the upper cover 101 , and the lifting spring 109 facilitates the quick release frame 105 to move upward. The lifting spring 109 is fixedly connected to the top wall of the inner cavity of the quick release frame 105 .

[0029] In this embodiment, the lifting spring 109 facilitates the quick release frame 105 to move and limit the quick release frame 105, thereby preventing the quick release frame 105 from affecting the installation and fixation during installation, which is beneficial to improving the installation efficiency and the practicality of the device.

[0030] The left and right sides of the bottom wall of the quick-release frame 105 are fixedly connected with rollers 110 . The rollers 110 roll to facilitate the movement of the clamping block 104 . The rollers 110 are located on the top wall of the clamping block 104 .

[0031] In this embodiment, the roller 110 is provided to facilitate rolling on the clamping block 104, so as to facilitate pushing the clamping block 104 to move, thereby avoiding friction support damage between the quick release frame 105 and the clamping block 104, which is beneficial to improving the service life of the device.
