[0024] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only."

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] like Figures 1 to 5As shown, a hand-push quick-release filter is characterized in that it includes a filter barrel 1, the filter barrel 1 is provided with a accommodating cavity, the filter barrel 1 is provided with a mounting hole 11, a filter cover 2 is provided at the position of the mounting hole 11, the lower side of the filter cover 2 is provided with a filter element extending into the accommodating cavity, the filter cover 2 is provided with a fixing shaft 21, the end of the fixing shaft 21 protrudes from the side position of the filter cover 2, the mounting hole 11 of the filter barrel 1 is provided with a slot 111 adapted to the fixing shaft 21, the outer side of the filter barrel 1 is provided with a rotating fixing structure 3, the rotating fixing structure 3 includes a fixing ear 31, the outer side of the fixing ear 31 is provided with a handle 32, the fixing ear 31 is provided with a fixing groove 311, the fixing groove 311 is provided with an opening connected to the slot 111, and the fixing shaft 21 is clamped in the fixing groove 311 through the slot 111.

[0028] After the fixing shaft 21 of the filter cover 2 is engaged in the fixing groove 311, the fixing ear 31 is rotated to make the fixing groove 311 rotate synchronously, so that the filter cover 2 can be fixed in the upper position of the filter barrel 1. When replacement is needed, the filter cover 2 and the filter element can be taken out by simply rotating the handle 32 and then rotating the fixing ear 31 to a specific position. The operation process is simple and quick.

[0029] During the rotation of the fixing ear 31, in order to press the fixing shaft 21 downward, thereby better fixing the filter cover 2 and the filter element to the filter barrel 1, in this embodiment, the fixing groove 311 is arc-shaped, and the arc of the fixing groove 311 gradually approaches the center of the fixing ear 31 from the open side. The opening position where the fixing groove 311 is connected to the outside is the outside, and the other end of the fixing groove 311 is the inside. The arc of the fixing groove 311 from the outside to the inside gradually approaches the center of the fixing ear 31. In this way, during the rotation of the fixing ear 31, the fixing shaft 21 located in the fixing groove 311 will approach the center of the fixing ear 31, that is, the fixing shaft 21 will move downward, thereby forming a situation in which the fixing ear 31 presses down the fixing shaft 21 and the filter cover 2 during rotation, so that the sealing between the filter cover 2 and the filter barrel 1 is better.

[0030] During the rotation of the fixing ear 31, in order to ensure the stability of the rotation of the packaging fixing ear 31, in this embodiment, a circular groove 112 that is adapted to the shape of the fixing ear 31 is provided on the outer side of the filter barrel 1, and the fixing ear 31 is clamped in the circular groove 112. When the handle 32 rotates, the fixing ear 31 rotates in the circular groove 112.

[0031] Furthermore, a protruding fixed end 113 is provided in the middle of the circular groove 112, and the fixing ear 31 is provided with a rotating ring 312 adapted to the fixed end 113. The rotating ring 312 is sleeved on the outside of the fixed end 113. In this way, under the action of the circular groove 112 and the fixed end 113, the fixing ear 31 can be engaged in the circular groove 112 through the rotating ring 312 and the overall shape. During the rotation process of the fixing ear 31, it can be ensured that the fixing ear 31 rotates around the center of the circle.

[0032] To facilitate the rotation of the fixing ears 31, in this embodiment, the handle 32 includes a handle lever 321 fixed to the outside of the fixing ears 31, and a handle push rod 322 fixed between the two handle levers 321. In this way, by pushing the handle push rod 322, the two handle levers 321 can be rotated, thereby rotating the fixing ears 31. At the same time, under the action of the handle push rod 322, the two fixing ears 31 can maintain a relatively fixed position, and then rotate while being engaged in the circular groove 112 of the filter barrel 1. During the rotation process, the fixing ears 31 will not be separated from the circular groove 112 of the filter barrel 1.

[0033] In order to ensure that the fixing ear 31 rotates synchronously with the handle lever 321 during the rotation process, in this embodiment, a positioning protrusion 313 is provided on the outside of the fixing ear 31, and a positioning groove 314 adapted to the positioning protrusion 313 is provided on the side of the handle lever 321. The handle lever 321 is fixed to the outside of the fixing ear 31 by a fastener.

[0034] Furthermore, for ease of operation, in this embodiment, when the fixing groove 311 of the fixing ear 31 is facing upward, the handle lever 321 is tilted upward. When the fixing ear 31 is rotated until the bottom of the fixing groove 311 contacts the fixing shaft 21, the handle lever 321 is tilted downward. That is, when the filter cover 2 is inserted into the fixing groove 311, the handle lever 321 is tilted upward. This does not affect the placement of the filter cover 2 and the filter element into the filter barrel 1. At the same time, after the filter cover 2 and the filter element are placed into the filter barrel 1, it is only necessary to press the handle 32 downward to rotate the fixing ear 31, thereby completing the engagement between the fixing ear 31 and the fixing shaft 21, making the operation process more convenient.

[0035] At this time, in order to be able to visually observe the status of the filter element in the filter barrel 1, in this embodiment, the filter barrel 1 includes a barrel body 12, a barrel head 13 is provided on the upper side of the barrel body 12, a base 14 is provided on the bottom of the barrel body 12, and the filter cover 2 is fixed on the upper side of the barrel head 13. The barrel body 12 and the barrel head 13 are connected by a flange, and the barrel body 12 is made of a transparent material. Specifically, the barrel body 12 can be made of acrylic or PC, so that during use, the status of the filter element in the filter barrel 1 can be visually observed, thereby facilitating other subsequent replacement work. After the barrel body 12 is made of transparent material, the barrel body 12 and the barrel head 13, that is, the base 14, are produced separately and then assembled together. Therefore, at this time, the barrel body 12 and the barrel head 13 are fixed by flange connection, and the barrel body 12 and the base 14 can be fixed by interference fit or adhesive.

[0036] Finally, in order to achieve filtration of the filter element, the barrel head 13 is provided with an inlet 15, which is connected to the interior of the filter element, and the bottom of the base 14 is provided with an outlet 16, which is connected to the barrel body 12. In this way, the liquid to be filtered can pass through the filter element, thereby achieving the filtering effect of the filter element.

[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
