Description

Technical Field

[0001] This application relates to the field of filter elements, and particularly to a filter with stable structure. Background Art

[0002] A filter is a component installed in an automobile to filter gasoline, engine oil or air. A filter paper is installed in the middle of the filter. The fluid passes through the filter paper and continues to flow. The solid impurities in the fluid can be filtered out and accumulate on one side of the filter paper, thus achieving the effect of protecting the automobile engine.

[0003] Related filters include an outer frame and a filter paper core. The outer frame includes a flat plate and longitudinal frames. Through holes are formed in the flat plate, and the longitudinal frames are arranged outside the through holes of the flat plate. The filter paper core is formed by folding the filter paper. The filter paper is folded to form a bent structure, thereby increasing the surface area of the filter paper core, enabling the filter paper core with a larger surface area to have a smaller volume. The filter paper core is arranged in the longitudinal frames, and the longitudinal frames play a role in fixing and protecting the side walls of the filter paper core, and can reduce the probability of deformation of the filter paper core. The user fixes the flat plate in the mechanical structure, and the fluid flows through the through holes, enabling the fluid to pass through the filter paper core and continue to flow. The filter paper core plays a role in filtering solid impurities in the fluid.

[0004] The above-mentioned related technical solutions have the following defects: During the driving of the automobile, the vibration in the mechanical structure is easily transmitted to the filter. After the outer frame is stressed, it is easily deformed and presses the filter paper core. The filter papers are stacked on each other, and it is difficult for the fluid to pass through the filter paper, thereby reducing the filtering effect of the filter paper core. Utility Model Content

[0005] In order to improve the structural stability of the filter, this application provides a filter with stable structure.

[0006] A filter with stable structure provided by this application adopts the following technical solutions:

[0007] A filter with stable structure includes an outer frame, a base, a filter paper core and a cover plate. The outer frame includes a first flat plate and a first longitudinal frame. The first longitudinal frame is a frame structure. The first longitudinal frame is connected to the first flat plate. A first ventilation hole is formed in the first flat plate. The first longitudinal frame is sleeved outside the first ventilation hole. The filter paper core is arranged on the first flat plate. The first longitudinal frame is sleeved outside the first flat plate. A second ventilation hole is formed in the base. The first longitudinal frame is inserted into the second ventilation hole. The base supports the first longitudinal frame. The cover plate is covered on the surface of the filter paper core. The cover plate is arranged parallel to the first flat plate.

[0008] By adopting the above technical solution, by arranging the first longitudinal frame on the first flat plate, the first longitudinal frame can be sleeved outside the filter paper core, thereby playing a role in protecting the filter paper core. By arranging a cover plate on the top of the filter paper core, the cover plate can play the effect of uniformly conducting stress. When stress is applied to the cover plate, the cover plate can uniformly conduct the stress to the filter paper core, thereby reducing the probability of the filter paper core being deformed by force. By sleeving a base outside the first longitudinal frame, the base can strengthen the structural strength of the first longitudinal frame, reduce the probability of the outer frame being deformed by force and squeezing the filter paper core, and the filter paper core can maintain a folded state, so that the surface area of the filter paper core remains at a relatively large level, with better permeability, and the structural stability of the filter is improved.

[0009] Optionally, the base includes a second flat plate and a second longitudinal frame. The second flat plate is a frame structure, and ventilation holes two are opened on the second flat plate. The second longitudinal frame is arranged around the ventilation holes two. When the outer frame is connected to the base, the second longitudinal frame fits with the first longitudinal frame, and the first flat plate fits with the second flat plate.

[0010] By adopting the above technical solution, by arranging the second flat plate on the second longitudinal frame, the second longitudinal frame can be sleeved outside the first longitudinal frame, thereby improving the structural stability of the first longitudinal frame. By arranging the second flat plate on the second longitudinal frame, the user can open through holes and set bolts on the second flat plate, thereby achieving the effect of fixedly installing the filter. The outer frame maintains its shape and structure stability and can maintain better structural strength.

[0011] Optionally, a plurality of first reinforcing ribs are arranged on the outer frame. The first reinforcing ribs are right-angled triangular plates. One side of the first reinforcing ribs is connected to the first flat plate, and the other side is connected to the first longitudinal frame. The plurality of first reinforcing ribs are arranged at intervals along the extending direction of the first longitudinal frame.

[0012] By adopting the above technical solution, by arranging the first reinforcing ribs on the outer frame, the first reinforcing ribs are connected to the first flat plate and the first longitudinal frame. When stress is borne on the outer frame, the probability of the first flat plate moving and deforming relative to the first longitudinal frame can be reduced, thereby playing the effect of improving the structural strength of the outer frame.

[0013] Optionally, a plurality of second reinforcing ribs are arranged on the base. The second reinforcing ribs are right-angled triangular plates. One side of the second reinforcing ribs is connected to the second flat plate, and the other side is connected to the second longitudinal frame. A groove is opened in the middle of the second reinforcing ribs, and the first reinforcing ribs are used to be inserted into the groove.

[0014] By adopting the above technical solution, by arranging the second reinforcing ribs on the base, the second reinforcing ribs play the effect of improving the strength of the base. By opening a groove in the middle of the second reinforcing ribs, when the outer frame is connected to the base, the first reinforcing ribs can be inserted into the second reinforcing ribs, thereby making the second reinforcing ribs fit and support the first reinforcing ribs, and improving the structural strength of the first reinforcing ribs and the second reinforcing ribs.

[0015] Optionally, a clamping frame is provided on the outer frame. The clamping frame is of a frame structure and is arranged in the first ventilation hole. The clamping frame is used to support the bottom surface of the filter paper core.

[0016] By adopting the above technical solution, by providing a clamping frame on the outer frame, the clamping frame can support the filter paper core in the first ventilation hole, reducing the probability of the filter paper core slipping in the first longitudinal frame. The clamping frame can enhance the structural strength of the first flat plate and reduce the probability of the first flat plate deforming and squeezing the filter paper core.

[0017] Optionally, a support rod is provided on the outer frame. The length direction of the support rod is parallel to the first flat plate. The support rod is arranged in the first ventilation hole, and both ends of the support rod are fixed to the outer frame.

[0018] By adopting the above technical solution, by providing a support rod on the outer frame and arranging the support rod in the first ventilation hole, when the outer frame is subjected to a horizontal stress, the support rod can provide support for the outer frame, thereby enhancing the structural strength of the outer frame.

[0019] Optionally, a plurality of pins are provided on the first flat plate. The pins are perpendicular to the first flat plate, and hooks are provided at the ends of the pins. A plurality of mating holes are provided on the second flat plate. The positions and dimensions of the pins correspond to the mating holes one by one.

[0020] By adopting the above technical solution, by providing pins on the first flat plate, the pins can penetrate the mating holes of the base, and hooks are provided at the ends of the pins. The hooks can be stuck on the second flat plate or other components, thereby enhancing the connection strength between the outer frame and the base.

[0021] Optionally, a plurality of guiding blocks are provided on the inner wall of the first longitudinal frame. The length direction of the guiding blocks is perpendicular to the first flat plate, and inclined surfaces are provided at one ends of the guiding blocks.

[0022] By adopting the above technical solution, by providing guiding blocks inside the first longitudinal frame, when the filter paper core is installed on the outer frame, the filter paper core first contacts the inclined surfaces on the guiding blocks. By pressing the filter paper core, the filter paper core can be gradually inserted into the first longitudinal frame, reducing the probability of the filter paper core deforming during the installation process.

[0023] In summary, the beneficial technical effects of the present application are as follows:

[0024] 1. By setting a first vertical frame on the first flat plate, the first vertical frame can be sleeved outside the filter paper core, thus playing a role in protecting the filter paper core. By setting a cover plate on the top of the filter paper core, the cover plate can achieve the effect of uniformly conducting stress. When stress is applied to the cover plate, the cover plate can uniformly conduct the stress to the filter paper core, thereby reducing the probability of the filter paper core being deformed by force.

Detailed implementation manners

[0035] The present application will be further described in detail below with reference to the accompanying drawings.

[0036] An embodiment of the present application discloses a filter with stable structure. Refer to Figure 1 , Figure 2 and Figure 7 , which includes an outer frame 1, a base 2, a filter paper core 3 and a cover plate 4. The filter paper core 3 is made of filter paper with better air permeability. The filter paper core 3 is formed into a cubic block structure by folding. The outer frame 1 and the base 2 are made of elastic materials. The outer frame 1 is sleeved on one side of the filter paper core 3. The cover plate 4 is bonded and covered on the top of the filter paper core 3. A ventilation hole I 111 is opened in the middle of the outer frame 1. The air in the ventilation hole I 111 passes through the filter paper core 3 and continues to flow. The solid impurities in the air can adhere to one side surface of the filter paper, so that the filter paper core 3 achieves the effect of filtering air. The base 2 is sleeved outside the outer frame 1. The base 2 is used for connecting with the mechanical structure, and the base 2 can play the role of fixing and supporting the outer frame 1.

[0037] Refer to Figure 1 and Figure 2 , the outer frame 1 includes a flat plate I 11 and a vertical frame I 12. The vertical frame I 12 is a frame structure. One side of the vertical frame I 12 is fixed on the flat plate I 11. The flat plate I 11 and the vertical frame I 12 are vertically arranged. The ventilation hole I 111 is opened on the flat plate I 11. The vertical frame I 12 surrounds the ventilation hole I 111. When the filter paper core 3 is installed on the outer frame 1, the filter paper core 3 is stuck in the vertical frame I 12, and the vertical frame I 12 fits against the side wall of the filter paper core 3, so as to support the filter paper core 3 to maintain a three-dimensional structure.

[0038] Refer to Figure 2 and Figure 3 , a plurality of guide blocks 121 are arranged on the inner wall of the vertical frame I 12. The guide blocks 121 are arranged at intervals along the circumferential direction of the vertical frame I 12. The length direction of the guide blocks 121 is perpendicular to the flat plate I 11. One side of the guide block 121 is provided with an inclined surface. When the filter paper core 3 is inserted into the vertical frame I 12, the filter paper core 3 contacts the inclined surface, so that the filter paper core 3 can slide into and be stuck in the vertical frame I 12.

[0039] Refer to Figure 3, a clamping frame 113 is provided in the first flat plate 11. The clamping frame 113 is of a frame structure and is installed in the first ventilation hole 111. The clamping frame 113 is arranged on the side of the guiding block 121 away from the inclined surface. The clamping frame 113 is arranged along the circumferential direction of the first longitudinal frame 12 and is used to clamp the bottom surface of the filter paper core 3. A plurality of through holes 112 are formed in the clamping frame 113, and the through holes 112 are arranged along the extending direction of the clamping frame 113. By forming the through holes 112 in the clamping frame 113, the weight of the clamping frame 113 can be reduced. The clamping frame 113 plays a supporting role and can improve the stability of the first flat plate 11. When stress is applied to the outer frame 1, the probability of deformation of the first flat plate 11 and the first ventilation hole 111 can be reduced, and thus the probability of deformation of the filter paper core 3 due to force can be reduced.

[0040] Refer to Figure 2 and Figure 4 , a support rod 114 is provided in the outer frame 1. Both ends of the support rod 114 are respectively fixed on the inner wall of the clamping frame 113, and the support rod 114 is parallel to the first flat plate 11. The support rod 114 is used to improve the structural strength of the clamping frame 113, thereby improving the strength and structural stability of the outer frame 1.

[0041] Refer to Figure 5 and Figure 6 , the base 2 includes a second flat plate 21 and a second longitudinal frame 22. The second longitudinal frame 22 is of a frame structure.

A second ventilation hole 211 is formed in the second flat plate 21, and the second longitudinal frame 22 is arranged around the second ventilation hole 211. When the base 2 is connected to the outer frame 1, the first longitudinal frame 12 is inserted into the second longitudinal frame 22, and the first flat plate 11 is arranged in contact with the second flat plate 21. Through holes can be formed in the second flat plate 21, and the second flat plate 21 is fixedly connected to the mechanical structure by bolts. The second longitudinal frame 22 is sleeved outside the first longitudinal frame 12, which has the effect of strengthening the structural stability of the first longitudinal frame 12.

[0042] Refer to Figure 4 , a plurality of first reinforcing ribs 13 are arranged outside the first longitudinal frame 12. The first reinforcing ribs 13 are right-angled triangular plates. One side of the first reinforcing ribs 13 is connected to the first flat plate 11, and the other side is connected to the first longitudinal frame 12. The plurality of first reinforcing ribs 13 are arranged at intervals along the extending direction of the first longitudinal frame 12. The first reinforcing ribs 13 are used to improve the positional stability of the first longitudinal frame 12 relative to the first flat plate 11.

[0043] Refer to Figure 6, there are multiple second reinforcing ribs 23 arranged outside the second vertical frame 22. The second reinforcing ribs 23 are right-angled triangular plates. One side of the second reinforcing rib 23 is connected to the second flat plate 21, and the other side is connected to the second vertical frame 22. The multiple second reinforcing ribs 23 are arranged at intervals along the extending direction of the second vertical frame 22. The positions of the second reinforcing ribs 23 correspond to those of the first reinforcing ribs 13 one by one. Grooves 231 are formed in the second reinforcing ribs 23. When the outer frame 1 is connected to the base 2, each first reinforcing rib 13 is inserted into a groove 231 of a second reinforcing rib 23, so that the second reinforcing rib 23 plays a role in fixing and supporting the first reinforcing rib 13.

[0044] Refer to Figure 4 , a support plate 122 is arranged on the first vertical frame 12. The support plate 122 is arranged higher than the first vertical frame 12, and the height of the support plate 122 is equal to the height of the filter paper core 3. The support plate 122 is used to support the cover plate 4. When the cover plate 4 is arranged on the filter paper core 3, the edge of the cover plate 4 abuts against the support plate 122. When stress is applied to the cover plate 4, the support plate 122 plays a supporting role for the cover plate 4, and can reduce the probability of the filter paper core 3 being deformed by force.

[0045] Refer to Figure 6 , a support rod 213 is arranged in the second flat plate 21. The support rod 213 is arranged in the second ventilation hole 211. The support rod 213 is parallel to the second flat plate 21, and both ends of the support rod 213 are respectively connected to the inner wall of the second ventilation hole 211. Two inserting cylinders 212 are arranged in the second flat plate 21. The two inserting cylinders 212 are fixed on the second flat plate 21. Both ends of the support rod 213 are respectively inserted into the inserting cylinders 212, so as to play a role in supporting the base 2 and improve the structural strength of the base 2.

[0046] Refer to Figure 6 , a plurality of pins 14 are arranged on the first flat plate 11. The pins 14 are perpendicular to the first flat plate 11. Hooks 141 are formed on the pins 14. A plurality of mating holes 24 are formed in the second flat plate 21. The positions and sizes of the mating holes 24 correspond to those of the pins 14 one by one. The pins 14 are used to be inserted into the mating holes 24, and the hooks 141 can be clamped with the second flat plate 21. In other embodiments, the hooks 141 can be clamped with other parts, so that other components can cover the filter paper core 3 and abut against the outer frame 1.

[0047] The implementation principle of the embodiment of the present application is as follows: By installing the outer frame 1 and the cover plate 4 on the filter paper core 3, the first vertical frame 12 is sleeved outside the filter paper core 3, so that the outer frame 1 and the cover plate 4 play a role in protecting the filter paper core 3, reducing the probability of the filter paper core 3 being deformed by force and affecting the filtering performance. By arranging the first reinforcing ribs 13 on the first flat plate 11 and the second reinforcing ribs 23 on the second flat plate 21, the structural strength of the outer frame 1 and the base 2 is further improved, reducing the probability of the outer frame 1 and the base 2 being deformed by force, and reducing the probability of the filter paper core 3 being squeezed and deformed.
