[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0024] See Figures 1-8 A filter handle assembly for filtering oil fumes includes a housing 1. The housing 1 is provided with a locking element 2 and a handle 3. Both the handle 3 and the locking element 2 are movably disposed on the housing 1, and the handle 3 and the locking element 2 are rotatably connected. When the locking element 2 is in the locked position, the handle 3 rotates and drives the locking element 2 to move in the unlocked position direction. When the handle 3 is released, the locking element 2 drives the handle 3 to elastically reset.

[0025] Both the locking element 2 and the handle 3 on the outer casing 1 are movably and rotatably connected. By rotating the handle 3, the locking element 2 can be driven to the unlocked position. Compared with the existing pull-out lock cylinder structure, no force is required to pull it out; only a slight rotation of the handle 3 is needed to unlock it, achieving a labor-saving effect. After releasing the handle 3, the locking element 2 causes the handle 3 to elastically return to its original position, eliminating the need for manual return and making the next operation more convenient. At the same time, the reset function ensures that the locking element 2 always returns to the locked position accurately, ensuring the stability of the filter after installation and preventing the filter from becoming loose due to displacement of the locking element 2.

[0026] The outer casing 1 is provided with a spring 4. The first end of the spring 4 abuts against the locking member 2, and the second end of the spring 4 abuts against the inside of the outer casing 1. When the locking member 2 moves away from the locked position and releases the handle 3, the locking member 2 returns to the locked position under the action of elasticity, and drives the handle 3 to return to the locked position.

[0027] When the locking element 2 moves away from the locked position and releases the handle 3, the elasticity of the spring 4 drives the locking element 2 to smoothly return to the locked position, and simultaneously drives the handle 3 to return to the original position. No manual intervention is required to return the locking element to its original position, thus improving ease of use.

[0028] The locking element 2 is provided with a groove 201, and the handle 3 is provided with a connector 301. The connector 301 is installed on the groove 201. When the locking element 2 is in the locked position, the handle 3 is rotated, and the connector 301 is limited to rotate on the groove 201, so as to drive the locking element 2 to move in the unlocked position direction.

[0029] The rotation of handle 3 is transmitted to the locking element 2 through connector 301. Since the rotation of handle 3 is limited, it will trigger the locking element 2 to move along the unlocked position.

[0030] The outer shell 1 is provided with a guide groove 101, and the locking member 2 is provided with a protrusion 202. The protrusion 202 is installed on the guide groove 101 and is limited to the guide groove 101 during the movement of the locking member 2.

[0031] The guide groove 101 of the outer casing 1 is installed correspondingly to the protrusion 202 of the locking element 2. The protrusion 202 is always confined within the guide groove 101 during the movement of the locking element 2. The guide groove 101 provides a clear movement trajectory for the locking element 2, ensuring that the locking element 2 can only move in the set directions of unlocking and locking, avoiding lateral deviation or skew, and ensuring the accuracy of unlocking and locking actions. The cooperation between the protrusion 202 and the guide groove 101 can reduce the shaking of the locking element 2 during movement.

[0032] The handle 3 is provided with a connector 301 and a connecting arm 302. The first end of the connector 301 is rotatably connected to the locking member 2, and the second end of the connector 301 is fixedly connected to the connecting arm 302. The outer shell 1 is provided with a limiting groove 102. The connecting arm 302 is installed on the limiting groove 102. The connecting arm 302 is limited to the limiting groove 102 during the rotation of the handle 3. The locking element 2 is provided with an anti-interference clearance groove 203 corresponding to the connecting arm 302.

[0033] One end of the connector 301 of the handle 3 is rotatably connected to the locking element 2, and the other end is fixed to the connecting arm 302. The limiting groove 102 of the outer shell 1 limits the connecting arm 302. When the handle 3 is rotated, the connecting arm 302 moves stably within the limiting groove 102, further precisely limiting the rotation trajectory of the handle 3, avoiding excessive rotation or deviation, making the force transmission more stable and the operation more effortless. The clearance groove 203 of the locking element 2 is specially designed for the connecting arm 302, which can effectively prevent the connecting arm 302 from interfering with the locking element 2 when rotating. The internal space of the outer shell 1 is fully utilized without increasing the overall volume.

[0034] The outer shell 1 is provided with a mounting limiting recess 103. The handle 3 is located on the mounting limiting recess 103 in the initial waiting state. The limiting recess 103 is provided with a positioning block 109 for abutting the handle 3.

[0035] The handle 3 is tucked into the limiting recess 103, without protruding outwards, reducing space occupation and making the product look cleaner.

[0036] The outer casing 1 includes a casing 104 and a cover 105, with a locking element 2 and a handle 3 installed between the casing 104 and the cover 105; The housing 104 is provided with a positioning element 106, and the locking element 2 is provided with a slot 204. The locking element 2 is installed on the housing 104, and the slot 204 is positioned relative to the outer periphery of the positioning element 106.

[0037] The slot 204 is positioned on the outer periphery of the positioning part 106, which can quickly and accurately install the locking part 2 and has the effect of preventing installation mistakes.

[0038] Both sides of the housing 104 are provided with baffles 107. The rear of the locking member 2 is limited between the two baffles 107. Both baffles 107 are provided with abutting ribs 108. Both sides of the locking member 2 are provided with protrusions 205. A spring 4 is provided between the protrusions 205 and the abutting ribs 108. The protrusion 205 is provided with a positioning protrusion 206 for positioning the spring 4.

[0039] The retaining edges 107 on both sides of the housing 104 limit the rear of the locking element 2 to prevent the locking element 2 from moving left and right inside the housing 1.

[0040] The double-sided spring design ensures a more balanced elastic force on the locking element 2, resulting in smoother reset and preventing tilting or jamming caused by unilateral force. The positioning protrusions 206 on the protrusion 205 precisely fix the spring 4, preventing it from falling off or shifting during use and ensuring stable transmission of elastic force.

[0041] The housing 104 is provided with a limiting groove 102 for limiting the rotation handle 3, and a limiting recess 103 and a positioning block 109 for positioning the handle 3.

[0042] The cover 105 is provided with a guide groove 101 for guiding the movement of the locking fastener 2, and the cover 105 is fixed to the housing 104 by fastening.

[0043] The cover 105 has a buckle 110 at the rear and a connecting rib 111 at the front. The housing 104 has a buckle hole and a connecting hole at the rear of the positioning member 106 of the housing 104. When the cover 105 and the housing 104 are assembled, the connecting rib 111 is inserted into the connecting hole and the buckle 110 is connected to the buckle hole.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
