Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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 creative work shall fall within the protection scope of the present utility model.

[0022] Embodiment 1

[0023] Please refer to Figures 1-5 , the present utility model provides the following technical solutions: An air filter convenient for installing a core material, including a sleeve 1, a mounting ring 2 is arranged on one side of the sleeve 1, a connecting rod 3 is arranged inside the mounting ring 2, one end of the connecting rod 3 is provided with a mounting block 4, a filter screen 8 is arranged on the surface of the mounting block 4, an air inlet pipe 6 is arranged on the other side of the sleeve 1, a shock absorption component 5 is arranged on the surface of the sleeve 1, and a waterproof component 7 is arranged on one side of the air inlet pipe 6.

[0024] Specifically, the shock absorption component 5 includes a bottom plate 51, a spring 52, a fixing ring 53, a support sleeve 54, a damping ring 55, a cylinder body 56 and a rubber buffer block 57. Among them, a bottom plate 51 is arranged on one side of the surface of the sleeve 1, a spring 52 is arranged at the upper end of the bottom plate 51, a fixing ring 53 is arranged on the surface of the spring 52, a support sleeve 54 is arranged at the upper end of the spring 52, a damping ring 55 is arranged on the inner surface of the support sleeve 54, a cylinder body 56 is arranged at the upper end of the support sleeve 54, and a rubber buffer block 57 is arranged on the inner surface of the cylinder body 56.

[0025] By adopting the above technical solution, when the air filter is affected by vibration, the pressure is transmitted to the bottom plate 51 through the sleeve 1. The bottom plate 51 pushes the spring 52 to move towards the support sleeve 54. The sleeve 1 pushes the rubber buffer block 57. The rubber buffer block 57 deforms under pressure and shares part of the pressure for the spring 52. At the same time, the bottom plate 51 pushes the fixing ring 53 to move towards the support sleeve 54. Friction occurs between the fixing ring 53 and the damping ring 55 inside the support sleeve 54, converting the elastic potential energy of the spring 52 into the frictional force between the fixing ring 53 and the damping ring 55, and the pressure caused by vibration is offset. When the spring 52 rebounds, the spring 52 pushes the bottom plate 51 to move towards the sleeve 1. At the same time, friction is generated between the fixing ring 53 and the damping ring 55, and the elastic potential energy of the spring 52 is weakened as it is converted into the frictional force between the fixing ring 53 and the damping ring 55, causing the spring 52 to push the bottom plate 51 to slowly return to the original position. Thus, the vibration impact on the core material inside the sleeve 1 can be reduced, ensuring the filtering effect of the core material and improving the working efficiency of the air filter.

[0026] Specifically, a limit ring is provided on the surface of the rubber buffer block 57.

[0027] By adopting the above technical solution, when the rubber buffer block 57 is under pressure, the limit ring can fix the position of the rubber buffer block 57, ensuring that the rubber buffer block 57 will not be displaced due to pressure, which is beneficial to improving the stability of the structure.

[0028] In the use of this embodiment: The pressure is transmitted to the bottom plate 51 through the sleeve 1. The bottom plate 51 pushes the spring 52 to move towards the support sleeve 54. The sleeve 1 pushes the rubber buffer block 57. The rubber buffer block 57 deforms under pressure and shares part of the pressure for the spring 52. At the same time, the bottom plate 51 pushes the fixing ring 53 to move towards the support sleeve 54. Friction occurs between the fixing ring 53 and the damping ring 55 inside the support sleeve 54, converting the elastic potential energy of the spring 52 into the frictional force between the fixing ring 53 and the damping ring 55, and the pressure caused by vibration is offset. When the spring 52 rebounds, the spring 52 pushes the bottom plate 51 to move towards the sleeve 1. At the same time, friction is generated between the fixing ring 53 and the damping ring 55, and the elastic potential energy of the spring 52 is weakened as it is converted into the frictional force between the fixing ring 53 and the damping ring 55, causing the spring 52 to push the bottom plate 51 to slowly return to the original position. Thus, the vibration impact on the core material inside the sleeve 1 can be reduced, ensuring the filtering effect of the core material and improving the working efficiency of the air filter. When the rubber buffer block 57 is under pressure, the limit ring can fix the position of the rubber buffer block 57, ensuring that the rubber buffer block 57 will not be displaced due to pressure, which is beneficial to improving the stability of the structure.

[0029] Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is as follows: Specifically, the waterproof component 7 includes a connecting sleeve 71, a pipe 72, a fixing sleeve 73, a sponge mesh 74, a limiting block 75, a water blocking sleeve 76, and a water-absorbing sponge 77. Among them, a connecting sleeve 71 is arranged on the surface of the air inlet pipe 6, a pipe 72 is arranged inside the connecting sleeve 71, a fixing sleeve 73 is arranged inside the pipe 72, a sponge mesh 74 is arranged inside the fixing sleeve 73, a limiting block 75 is arranged on the surface of the pipe 72, a water blocking sleeve 76 is arranged on one side of the limiting block 75, and a water-absorbing sponge 77 is arranged inside the water blocking sleeve 76.

[0031] By adopting the above technical solution, when installing the waterproof component 7, the connecting sleeve 71 is sleeved on the surface of the air inlet pipe 6, the sponge mesh 74 is fixed inside the fixing sleeve 73. After the fixing sleeve 73 is inserted into one end inside the pipe 72, one end of the pipe 72 is aligned with one end of the air inlet pipe 6, so that the connecting sleeve 71 sleeves one end of the pipe 72. The water blocking sleeve 76 with the water-absorbing sponge 77 is sleeved on the other end of the pipe 72 until one side of the water blocking sleeve 76 contacts the limiting block 75, and then the installation of the waterproof component 7 can be completed. At this time, the air with liquid enters the water blocking sleeve 76, and the water-absorbing sponge 77 inside the water blocking sleeve 76 can adsorb the liquid, reducing the liquid entering the pipe 72. The sponge mesh 74 inside the pipe 72 allows air to pass through and adsorbs the remaining liquid. Thus, it can prevent the liquid from entering the sleeve 1 through the air inlet pipe 6 and polluting the core material inside the sleeve 1, which is beneficial to extending the service life of the core material.

[0032] Specifically, a clamping groove is arranged inside one end of the pipe 72, and a clamping block is arranged on the surface of the fixing sleeve 73. The clamping block corresponds to the clamping groove.

[0033] By adopting the above technical solution, when air passes through the pipe 72, the clamping block can fix the position of the fixing sleeve 73, preventing the fixing sleeve 73 from moving and affecting the filtering effect.

[0034] Specifically, an external thread is arranged on the surface of one end of the pipe 72, and an internal thread is arranged on the inner surface of the water blocking sleeve 76.

[0035] By adopting the above technical solution, when it is necessary to clean the inside of the water blocking sleeve 76, the staff can rotate the water blocking sleeve 76. The internal thread inside the water blocking sleeve 76 cooperates with the external thread on the surface of the pipe 72, enabling the water blocking sleeve 76 to be detached from the pipe 72, which is convenient for the staff to clean and replace the inside of the water blocking sleeve 76.

[0036] In the use of this embodiment: The connecting sleeve 71 is sleeved on the surface of the intake pipe 6, the sponge mesh 74 is fixed inside the fixing sleeve 73. After inserting the fixing sleeve 73 into one end of the pipe 72, one end of the pipe 72 is aligned with one end of the intake pipe 6, so that the connecting sleeve 71 sleeves one end of the pipe 72. The water-blocking sleeve 76 with the water-absorbing sponge 77 is sleeved on the other end of the pipe 72 until one side of the water-blocking sleeve 76 touches the limit block 75, then the installation of the waterproof component 7 can be completed. At this time, the air with liquid enters into the water-blocking sleeve 76. The water-absorbing sponge 77 inside the water-blocking sleeve 76 can adsorb the liquid, reducing the liquid entering into the pipe 72. The sponge mesh 74 inside the pipe 72 allows air to pass through and adsorbs the remaining liquid. Thus, it can prevent the liquid from entering into the sleeve 1 through the intake pipe 6 and polluting the core material inside the sleeve 1, which is beneficial to extending the service life of the core material. When the air passes through the pipe 72, the block can fix the position of the fixing sleeve 73 to prevent the fixing sleeve 73 from moving and affecting the filtering effect. When it is necessary to clean the inside of the water-blocking sleeve 76, the staff can rotate the water-blocking sleeve 76. The internal thread inside the water-blocking sleeve 76 cooperates with the external thread on the surface of the pipe 72, enabling the water-blocking sleeve 76 to be separated from the pipe 72, which is convenient for the staff to clean and replace the inside of the water-blocking sleeve 76.

[0037] The damping ring 55 in the present utility model is a publicly known prior art, and the selected model is SH7432.

[0038] The water-absorbing sponge 77 in the present utility model is a publicly known prior art, and the selected model is ZH9154.

[0039] The structures and working principles of the mounting ring 2, connecting rod 3, mounting block 4 and filter net 8 in the present utility model have been disclosed in an air filter convenient for core material installation with the Chinese patent application number 202323412692.4.

[0040] Working principle and usage process of the present utility model: When the air filter facilitating the installation of the core material is in use, pressure is transmitted through the sleeve 1 to the bottom plate 51. The bottom plate 51 pushes the spring 52 to move towards the support sleeve 54. The sleeve 1 pushes the rubber buffer block 57. The rubber buffer block 57 deforms under pressure, sharing part of the pressure for the spring 52. At the same time, the bottom plate 51 pushes the fixing ring 53 to move towards the support sleeve 54. Friction occurs between the fixing ring 53 and the damping ring 55 inside the support sleeve 54, converting the elastic potential energy of the spring 52 into the frictional force between the fixing ring 53 and the damping ring 55, and the pressure caused by vibration is cancelled out. When the spring 52 rebounds, the spring 52 pushes the bottom plate 51 to move towards the sleeve 1. At the same time, friction occurs between the fixing ring 53 and the damping ring 55, and the elastic potential energy of the spring 52 is converted into the frictional force between the fixing ring 53 and the damping ring 55 and weakened, enabling the spring 52 to push the bottom plate 51 to slowly return to the original position. Thus, the vibration impact on the core material inside the sleeve 1 can be reduced, ensuring the filtering effect of the core material and improving the working efficiency of the air filter. When the rubber buffer block 57 is under pressure, the limit ring can fix the position of the rubber buffer block 57, ensuring that the rubber buffer block 57 will not displace due to pressure, which is beneficial to improving the structural stability. When installing the waterproof component 7, the connecting sleeve 71 is sleeved on the surface of the intake pipe 6. The sponge mesh 74 is fixed inside the fixing sleeve 73. After inserting the fixing sleeve 73 into one end of the pipe 72, one end of the pipe 72 is aligned with one end of the intake pipe 6, so that the connecting sleeve 71 sleeves one end of the pipe 72. The water blocking sleeve 76 with the water-absorbing sponge 77 is sleeved on the other end of the pipe 72 until one side of the water blocking sleeve 76 touches the limit block 75, and the installation of the waterproof component 7 can be completed. At this time, the air with liquid enters the water blocking sleeve 76. The water-absorbing sponge 77 inside the water blocking sleeve 76 can adsorb the liquid, reducing the liquid entering the pipe 72. The sponge mesh 74 inside the pipe 72 allows air to pass through and adsorbs the remaining liquid. Thus, it can prevent the liquid from entering the sleeve 1 through the intake pipe 6 and polluting the core material inside the sleeve 1, which is beneficial to extending the service life of the core material. When air passes through the pipe 72, the block can fix the position of the fixing sleeve 73 to prevent the fixing sleeve 73 from moving and affecting the filtering effect.

[0041] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
