Description

Technical Field

[0001] The present invention relates to the technical field of vehicle air-conditioning filter elements, and in particular to a detachable air-conditioning filter element. Background Art

[0002] A car cabin filter is a filter used to purify the air in a car's cabin. The general filtered substances refer to impurities contained in the air, such as tiny particles, pollen, bacteria, industrial waste gas and dust. The effect of the cabin filter is to prevent such substances from entering the air-conditioning system and damaging it, providing a good air environment for the passengers in the car and protecting their health.

[0003] At present, the non-woven filter element for automotive air conditioning is basically composed of non-woven paper, head frame, side frame and glue. When the filter element reaches the end of its life, the filter element will be discarded as a whole, resulting in waste of frame materials and environmental pollution. Summary of the Invention

[0004] The purpose of the present invention is to provide a detachable air conditioning filter element in order to solve the above problems. When replacing the filter element, only the filter material needs to be replaced, and the remaining materials can be recycled, effectively avoiding material waste.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A frame structure for a removable air conditioning filter element includes a side frame, which is a square frame with an open end. Mounting grooves for fixing and installing filter materials are provided on both sides of the side frame. The side frame is a foldable structure. The side frame is composed of multiple side frame rotating parts. Adjacent side frame rotating parts are connected by side frame rotating pins. Each side frame rotating part can rotate to achieve folding of the side frame.

[0007] Furthermore, the installation groove is a sawtooth-shaped installation groove, and the sawtooth-shaped installation groove has the following characteristics: the sawtooth-shaped installation groove does not hinder the installation of the filter material; and the filter material needs to be destroyed when it is taken out in the reverse direction.

[0008] Furthermore, the length of the side frame rotating member matches the folded thickness of the filter material.

[0009] Furthermore, the angle at which the side frame rotating member rotates along the side frame rotating pin matches the folding angle of the filter material.

[0010] Furthermore, it also includes a head frame, which is installed at the opening at one end of the side frame.

[0011] A removable air conditioning filter element includes a side frame and a head frame. The side frame is a square frame with an open end. Installation grooves for fixing and installing filter materials are provided on both sides of the side frame. The filter material is loaded into the installation groove from the open side of the side frame. The head frame is provided at the outer end of the filter material. Along the filter material installation direction, the side frame is a foldable structure. The side frame is composed of multiple side frame rotating parts. The adjacent two side frame rotating parts are connected by side frame rotating pins. Each side frame rotating part can rotate to achieve folding of the side frame.

[0012] The filter element structure fixes the filter material in the mounting grooves by arranging mounting grooves on both sides of the side frame, and since the side frame is formed into a folded shape by the combined structure of the side frame rotating member and the side frame rotating pin, the filter material can be folded when installing the filter material.

[0013] Furthermore, the installation groove is a serrated installation groove, which enhances the reliability of the installation of the filter material and can effectively prevent the filter material from falling out after installation.

[0014] Furthermore, the serrated installation groove has the following characteristics: along the filter material installation direction, the serrated installation groove does not hinder the installation of the filter material; in the reverse direction, the filter material is stuck by the serrated shape, and the filter material needs to be removed violently and is destroyed after removal. The serrated installation groove allows one-way installation of the filter material.

[0015] Furthermore, the length of the side frame rotating member matches the folded thickness of the filter material, and the height of each small fold of the foldable side frame is higher than the height of the filter element housing, and there is a certain proportional relationship, which cannot be too small or too large.

[0016] Furthermore, the angle at which the side frame rotating member rotates along the side frame rotating pin matches the angle at which the filter material is folded. Each two sections of the side frame rotating member are connected by a side frame rotating pin. Each section can rotate in a specified direction and has a maximum angle.

[0017] Furthermore, the length and width of the filter material match the length and width of the side frame. After the filter material is fixed, the four sides of the filter element are sealed and leak-proof.

[0018] Furthermore, the filter material is origami, and the head frame is adhered to the filter material.

[0019] Furthermore, after the filter material, side frame and head frame are installed as a whole, the whole is installed in the filter element housing, the opening of the filter element housing is sealed with the housing end cover, and the filter element as a whole is firmly installed inside the filter element housing without loosening. After the side frame, filter material and head frame are installed as a whole, the whole can be automatically bent when pushed into the housing, and the overall length after bending meets the length of the filter element housing.

[0020] Furthermore, the opening of the filter element housing can be in the length direction or in the width direction. When the installation opening is in the width direction, the filter material, side frame and head frame are first bent and then installed as a whole into the filter element housing.

[0021] Compared with the existing technology, the filter element structure of this invention is removable and replaceable. When the filter material reaches the end of its service life, the filter material can be removed and replaced with a new one or freely selected according to performance requirements, while other components (frame materials, etc.) can continue to be used. Compared with the existing filter element, when replacing the filter element, only the filter material needs to be replaced, which causes less pollution to the environment, can be recycled, and is more environmentally friendly. The filter element with a single filter material is more competitive in the market than the filter element with a non-woven fabric frame, and the installation is flexible. The serrated installation groove effectively ensures the firmness of the filter material installation to avoid loosening. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example

[0030] like Figure 1 、 23. A detachable air conditioning filter element includes a side frame 2 and a head frame 3. The filter material 1 is installed in the side frame 2. The filter material 1 can be made of origami. The head frame 3 is glued to the filter material 1. The side frame 2 is a square frame with an open end. Both sides of the side frame 2 are provided with mounting grooves 7 for fixing and installing the filter material 1. The mounting grooves 7 are serrated mounting grooves. The serrated mounting grooves have the following characteristics: along the installation direction of the filter material 1, the serrated mounting grooves 7 do not hinder the installation of the filter material 1; when reversed, the filter material 1 is serrated and stuck to the filter material 1. The filter material 1 needs to be removed violently. The filter material 1 is installed in the mounting groove 7 from the open side of the side frame 2. Along the installation direction of the filter material 1, the serrated mounting grooves effectively ensure the firmness of the filter material installation and prevent it from loosening.

[0031] The side frame 2 is a foldable structure. The side frame 2 is composed of multiple side frame rotating parts 21. The adjacent two side frame rotating parts 21 are connected by a side frame rotating pin 4. Each side frame rotating part 21 can rotate to achieve the folding of the side frame 2 and the filter material 1.

[0032] The length of the side frame rotating member 21 matches the folded thickness of the filter material 1. The height of each small fold of the foldable side frame is higher than the height of the filter cartridge housing, and there is a certain proportional relationship, which cannot be too small or too large. The angle at which the side frame rotating member 21 rotates along the side frame rotating pin 4 matches the angle at which the filter material 1 folds. Each section of the side frame rotating member is connected by the side frame rotating pin. Each section can rotate in a specified direction and has a maximum angle. The length and width of the filter material 1 match the length and width of the side frame 2. After the filter material 1 is fixed, the four sides of the filter cartridge are sealed and leak-proof.

[0033] like Figure 4 After the filter material 1, side frame 2 and head frame 3 are installed as a whole, the whole is installed in the filter housing 5, and the opening of the filter housing 5 is sealed with the housing end cover 6. The opening of the filter housing 5 can be in the length direction or in the width direction. When the installation opening is in the width direction, the filter material 1, side frame 2 and head frame 3 are bent first, and then the whole is installed in the filter housing 5. Figure 5 This is the final effect diagram of the present invention installed in the whole vehicle.

[0034] When the filter material reaches the end of its service life, it can be removed and replaced with a new one, or you can freely choose a filter material that meets the use requirements according to performance requirements, while other components such as the frame material can continue to be used, which causes less pollution to the environment, can be recycled, and is more environmentally friendly. The filter element with a single filter material is more competitive in the market than the filter element with a non-woven fabric frame, and the installation is flexible.

[0035] The above description of the embodiments is intended to facilitate understanding and use of the invention by those skilled in the art. It will be apparent that those skilled in the art can readily make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the present invention is not limited to the above-described embodiments.
