Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filter cover. Background Art

[0002] A filter is a component that filters impurities or gases through filter paper. It typically refers to automotive filters, which are engine accessories. Based on their filtering function, they are categorized into: oil filters, fuel filters (gasoline filters, diesel filters, oil-water separators, hydraulic filters), air filters, and cabin air filters. An engine has three filters: air, oil, and fuel, commonly referred to as the "three filters." Together with the cabin air filter, these filters are commonly known as the "four filters." These filters are responsible for filtering the lubrication system, the combustion system, the engine intake system, and the cabin air circulation system, respectively. The filter production process typically requires manual application of glue to the end caps before connecting the filter element end to the end caps. This complex process, coupled with tight connections, creates high operating pressure. Therefore, a convenient end cap is a critical requirement for filter production.

[0003] For example, an environmentally friendly filter cover disclosed in authorization announcement number CN221053775U includes a housing and a cover body. The housing is a single-sided closed cylinder. A clamping block and a limiting block are provided on the inner top of the housing. The clamping blocks are fixed in three numbers and distributed circumferentially. The limiting blocks are fixed in four numbers and distributed circumferentially. The limiting blocks are located outside the clamping blocks. The lower end outer surface of the housing is provided with an external thread. The lower end outer surface of the housing is provided with a positioning portion. The positioning portions are fixed in two numbers and evenly distributed. Both positioning portions are located on the external thread. The upper end inner surface of the cover body is provided with an internal thread. The housing is threadedly connected to the cover body via the external thread. The utility model facilitates disassembly and installation between the housing and the cover body through the threaded connection between the housing and the cover body, so that the filter element inside the housing can be replaced, ensuring the normal use of the filter without wasting other parts, thereby achieving an environmentally friendly effect. However, the structure of this utility model is relatively complicated, which makes it difficult for workers to install the filter element and the end cover conveniently. Therefore, we propose a filter cover to solve the installation problem of this utility model and improve the convenience and practical effect of this utility model. Utility Model Content

[0004] The purpose of the present utility model is to provide a filter cover to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A filter cover comprises a filter end cover, the filter end cover comprising an end cover outer shell and an end cover inner wall, a glue injection mechanism being arranged inside the filter end cover outer shell; the glue injection mechanism comprising a glue liquid chamber, the glue liquid chamber being arranged in a cavity between the filter end cover outer shell and the end cover inner wall, the end cover inner wall being provided with four glue liquid outlets, the glue liquid outlets being arranged in a circular array with the filter end cover center as the axis, and the inner bottom surface of the glue liquid chamber being designed to be inclined to the glue liquid outlet direction.

[0007] Preferably, the glue outlet is provided with a sliding slot, and a glue baffle is slidably installed inside the sliding slot.

[0008] Preferably, a rotating rod is fixedly provided on one side of the glue baffle, a baffle is provided on one side of the rotating rod, and a top end of the baffle is fixedly provided on the inner wall of the end cover.

[0009] Preferably, the baffle rod and the rotating rod are not connected to each other, the baffle rod is made of PP material, and the rotating rod is made of PVC material.

[0010] Preferably, the glue baffle is arranged to cover the glue outlet, and the contact surfaces thereof are in close contact with each other.

[0011] Preferably, an inner limiting ring is provided at the inner center position of the filter end cover, and the circular groove between the inner limiting ring and the inner wall of the end cover is a glue injection groove.

[0012] Preferably, a gluing hole and a vent hole are provided at the top end of the filter end cover, and the gluing hole is provided with a one-way venting glue valve.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This filter cover, through the arrangement of the glue chamber, glue outlet, sliding slot and glue baffle, allows the filter element end cover to be installed by rotating the filter element end cover clockwise to drive the glue baffle to move along the sliding slot, thereby opening the glue outlet and allowing the glue to flow out into the glue injection slot, thereby achieving mutual bonding and fixation between the filter element end and the filter element end cover. The conventional operation method generally involves first using glue injection equipment to inject glue into the end cover, and then installing the filter element. The installation process must be closely connected, otherwise the glue will easily coagulate and become ineffective, resulting in waste. This method has many operation processes and high pressure, resulting in low efficiency. The filter cover in this application achieves the effect of simultaneous installation and glue injection. In addition, the relatively closed storage method of the glue greatly delays the glue coagulation time and relieves the operating pressure of the staff.

[0015] 2. This filter cover, through the relative limiting setting between the blocking rod and the rotating rod, prevents the filter element end cover from being caused by external force to move the rotating rod after the glue is injected, thereby causing the glue outlet to open prematurely and causing the glue to flow out, thereby improving the convenience of use and practical effect of the filter cover.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 4 As shown, the utility model provides a technical solution:

[0023] A filter cover includes a filter end cover 100, wherein the filter end cover 100 includes an end cover outer shell 101 and an end cover inner wall 102, and a glue injection mechanism is provided inside the filter end cover 100 outer shell; the glue injection mechanism includes a glue liquid cavity 200, and the glue liquid cavity 200 is provided in a cavity between the filter end cover 100 outer shell and the end cover inner wall 102, and the end cover inner wall 102 is provided with four glue liquid outlets 201, and the glue liquid outlets 201 are arranged in a circular array with the center of the filter end cover 100 as the axis center, and the inner bottom surface of the glue liquid cavity 200 is designed to be inclined to the direction of the glue liquid outlet 201.

[0024] In this embodiment, preferably, the glue outlet 201 is provided with a sliding slot 202 , and a glue baffle 203 is slidably installed inside the sliding slot 202 .

[0025] In this embodiment, preferably, a rotating rod 204 is fixedly provided on one side of the glue baffle 203 , a baffle 205 is provided on one side of the rotating rod 204 , and a top end of the baffle 205 is fixedly provided on the inner wall 102 of the end cover.

[0026] In this embodiment, preferably, the blocking rod 205 and the rotating rod 204 are not connected to each other, the blocking rod 205 is made of PP material, and the rotating rod 204 is made of PVC material.

[0027] In this embodiment, preferably, the glue baffle 203 is arranged to cover the glue outlet 201, and the contact surfaces thereof are in close contact with each other.

[0028] In this embodiment, preferably, an inner limiting ring 103 is provided at the center position inside the filter end cover 100 , and the circular groove between the inner limiting ring 103 and the inner wall 102 of the end cover is a glue injection groove 104 .

[0029] In this embodiment, preferably, a gluing hole 105 and a vent hole 106 are provided at the top of the filter end cover 100, and the gluing hole 105 is provided with a one-way venting glue valve.

[0030] When using the filter cover of this embodiment, glue is first injected into the glue chamber 200 through the glue hole 105 and vent hole 106 provided at the top of the filter end cap 100. Since the glue hole 105 is provided with a one-way venting glue valve, when the glue needle is pulled out, the glue hole 105 automatically closes, achieving the glue injection effect. In actual use, in order to fix the position of the filter element, the filter end cap 100 needs to be glued to both ends of the filter element. First, the filter end cap 100 is laid flat, and then one end of the filter element is vertically installed inside the glue injection slot 104, so that the rotating rod 204 is engaged with the filter element, and then the filter end cap 100 is rotated clockwise, so that the rotating rod 204 drives the glue baffle 203 to slide counterclockwise along the sliding slot 202, thereby realizing the open state of the glue outlet 201. Since the bottom surface of the glue cavity 200 is designed to be inclined in the direction of the glue outlet 201, at this time, the glue flows into the glue injection slot 104, achieving the effect of mutual adhesion between the end of the filter element and the filter end cap 100. Among them, the baffle 205 is set on one side of the rotating rod 204, which plays a limiting role on the rotating rod 204, avoiding the risk of the glue baffle 203 shifting due to external factors after the glue of the filter end cap 100 is completed, further leading to the risk of glue leakage. In addition, the blocking rod 205 is made of PP material and has a certain degree of flexibility. Therefore, when the rotating rod 204 rotates, the blocking rod 205 can be deformed and will not hinder the movement of the rotating rod 204. The structural design is ingenious and practical.
