[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 、 2, as shown in Figures 3, 4, 5, and 6, the present utility model provides a technical solution: a spring automatic clamping structure, including: a base 4, the base 4 is a circular tube with a partition fixedly connected in the middle; a filter element cover 5, the filter element cover 5 is clamped to the bottom of the base 4 through a clamping portion, a limiting post 8 is fixedly connected to the top of the base 4, the clamping portion includes a top block 3 slidably arranged on the top of the base 4 and a spring 2 for driving the top block 3 to reset, which is used to interlock with the limiting post 8; a limiting protrusion 11 is fixedly connected to the top of the filter element cover 5, and an arc-shaped groove 10 cooperating with the limiting protrusion 11 is provided on the partition in the middle of the base 4, which is used to prevent misassembly of the product during installation.

[0024] It should be noted that during the installation process of the present utility model, first, the spring 2 and the top block 3 are fixed on the base 4. By means of screws, the decorative cover 1 is fixed on the base 4, and at the same time, the components of the spring 2 and the top block 3 are fixed. The base 4 is covered on the top of the filter element cover 5, and the limiting post 8 squeezes and pushes the top block 3 to both sides. During this process, the spring 2 is compressed to both sides. When the round table at the top of the limiting post 8 is misaligned with the top block 3, under the reset action of the spring 2, the top block 3 is stuck between the limiting post 8 and the base 4. At the same time, the limiting protrusion 11 on the top of the filter element cover 5 cooperates with the arc-shaped groove 10 at the bottom of the base 4, and the limiting protrusion 11 slides in the arc-shaped groove 10, so that the base 4 can only rotate within a certain range. The top block 3 and the spring 2 are stuck in the middle of the limiting post 8 and cannot be pulled out, but can rotate circumferentially. By rotating the handle on the decorative cover 1, the rotation of the base 4 is driven, and the filter element cover remains stationary, so that the buckle ears on the base 4 are fixed on the whole machine, so as to realize the disassembly and assembly tooling of the filter element. At the same time, because the fixed position on the whole machine is close to the position of the handle and the force arm is short, the torque used is small, and the disassembly and assembly are convenient.

[0025] Please refer to Figure 1 , 2 , as shown in Figures 4, a decorative cover 1 is fixedly connected to the top of the base 4.

[0026] It should be noted that the decorative cover 1 of the present utility model includes a top cover and a handle. The handle is a rectangular groove and is vertically fixedly connected to the top of the top cover. The decorative cover 1 is fixedly connected to the base 4 by means of screw locking. Rotating the handle on the decorative cover drives the rotation of the filter element, so as to achieve the effect of disassembling and assembling the filter element, and at the same time optimize the aesthetics of the product.

[0027] Please refer to Figure 2 , 3 , as shown in Figures 4, a limiting groove 6 is fixedly connected to the partition of the base 4, the top block 3 is slidably connected to the limiting groove 6, the spring 2 is located between the top block 3 and the end of the limiting groove 6, the limiting post 8 is a T-shaped structure, and the top of the limiting post 8 is a frustum-shaped structure. The end of the top block 3 is provided with a frustum-shaped structure for cooperation with the arc-shaped groove.

[0028] It should be noted that the top block 3 of the present utility model slides inside the limit groove 6, and the limit groove 6 limits the side of the top block 3 to ensure that the top block 3 moves along the length direction of the limit groove 6. In the natural state, the spring 2 is in an elastic state. Since the bottom of one end of the top block 3 is a bevel structure, when the base 4 and the filter element cover 5 are assembled, the limit post 8 presses against the bottom bevel of the top block 3, thereby pushing the top block 3 open to both sides. When the frustum structure at the top of the limit post 8 moves above the top block 3, under the reset action of the spring 2, the top block 3 is inserted between the top of the limit post 8 and the base 4, thereby clamping the base 4 and the filter element cover 5.

[0029] Please refer to Figure 1 , 3 , Figures 4 and 5, a filter cartridge 9 is fixedly connected to the bottom of the filter element cover 5, and two limit clamping blocks 7 are symmetrically and fixedly connected to the outside of the base 4 for fastening with the whole machine housing.

[0030] It should be noted that a filter element is installed inside the filter cartridge 9 of the present utility model, so as to form a complete filtering system with the filter element cover 5 and the filter cartridge 9 at the top. By rotating the decorative cover 1 to drive the rotation of the base 4, the limit clamping blocks 7 on the base 4 are used for fastening and disassembling functions with the whole machine housing.
