Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a quick-release structure for the filter screen of a medical air purification and disinfection device. Background Technology

[0002] As medical air purification and disinfection devices are used for longer periods, a lot of dust and impurities accumulate on the surface of the internal filter screen. The filter screen needs to be removed for cleaning and replacement. However, existing medical air purification and disinfection devices are generally fixed to the filter screen with bolts, which is very inconvenient to disassemble and reduces the efficiency of cleaning and maintaining the filter screen.

[0003] To address the above issues, patent document CN211822881U discloses a quick-release filter structure for a medical air purification and disinfection device. This structure includes a housing, a filter body, a HEPA filter element, and a motor. A spring is installed inside the housing, and the filter body, containing the HEPA filter element, is also installed inside. A groove is formed on the lower surface of the locking block, and a spiral pattern is formed on the upper surface of the filter body. A limiting block is fixed to the inner wall of the housing, and an mounting block is connected to the upper surface of the filter body. The mounting block houses the motor, and an air outlet is located on the upper surface of the mounting block. In this quick-release filter structure, a support plate is installed inside the housing, and a spring is fixed below the support plate. When the locking block disengages from the limiting block, the spring's resetting action ejects the entire filter body, enabling rapid disassembly and improving the efficiency of cleaning and maintenance.

[0004] However, the spring structure in the quick-release filter of existing medical air purification and disinfection devices is installed at the bottom of the housing, which makes it inconvenient to replace or disassemble the spring inside the housing. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-release structure for the filter screen of a medical air purification and disinfection device, which solves the problem that the spring structure in the existing quick-release structure for the filter screen of a medical air purification and disinfection device is installed at the bottom of the housing, making it inconvenient to replace or disassemble the spring inside the housing.

[0006] To achieve the above objectives, this utility model provides a quick-release structure for the filter screen of a medical air purification and disinfection device, including a housing, a filter screen body, a fixed base plate, and a quick-release mechanism.

[0007] The quick-release mechanism includes a mounting box, a spring assembly, multiple lifting columns, and plug-in locking pins. The mounting box is installed on the outer bottom of the housing, and a cover plate is snapped onto the end face of the mounting box. The spring assembly is located on the inner bottom of the mounting box, and multiple lifting columns are arranged on the upper surface of the spring assembly. The ends of the multiple lifting columns away from the spring assembly pass through the mounting box and the housing in sequence. Each lifting column has a supporting plate at its inner bottom end in the housing, which abuts against the bottom of the fixed base plate. The side of the fixed base plate has a limit hole, and the plug-in locking pins are arranged on the outer wall of the housing, with the plug-in locking pins adapted to the limit holes.

[0008] The spring assembly includes a mounting base plate, a mounting top plate, and multiple return springs. The mounting base plate is installed at the inner bottom of the mounting box, and multiple return springs are installed on the upper surface of the mounting base plate. The mounting top plate is installed at the end of the multiple return springs away from the mounting base plate.

[0009] The mounting base plate has a first disassembly handle on the side facing the cover plate, and the cover plate has a second disassembly handle on the side outside the mounting box.

[0010] Each of the reset springs includes a spring body, a first mounting ring, and a second mounting ring. The spring body has the first mounting ring and the second mounting ring respectively at both ends. The first mounting ring is detachably connected to the mounting base plate, and the second mounting ring is detachably connected to the mounting top plate.

[0011] The fixed base plate has two limiting holes and two plug-in locking pins, with each plug-in locking pin corresponding to one limiting hole.

[0012] This utility model discloses a quick-release structure for the filter screen of a medical air purification and disinfection device. When cleaning and maintenance of the filter screen body inside the housing is required, simply remove the plug-in locking post, disengaging it from the limiting locking hole. Under the reset action of the spring assembly, the lifting column and the supporting plate cooperate to apply force to the fixed base plate, popping the filter screen body out as a whole, thus achieving quick disassembly of the filter screen body. Furthermore, when the spring assembly needs to be replaced, simply remove the cover plate to complete the disassembly and assembly of the spring assembly at the mounting box. Since the mounting box is located outside the housing, the operation of replacing the spring assembly is more convenient. Attached Figure Description

[0021] This utility model provides a quick-release structure for the filter of a medical air purification and disinfection device: it includes a housing 101, a filter body 102, a fixed base plate 103, and a quick-release mechanism. The quick-release mechanism includes a mounting box 104, a spring assembly, multiple lifting columns 105, and a plug-in locking column 106. The spring assembly includes a mounting base plate 107, a mounting top plate 108, and multiple return springs. Each return spring includes a spring body 109, a first mounting ring 110, and a second mounting ring 111. This solution solves the problem that in existing quick-release structures for medical air purification and disinfection devices, the spring structure is installed at the inner bottom of the housing 101, making replacement and disassembly of the springs in the housing 101 inconvenient. Therefore, this solution can be used in the quick-release structure of the filter of a medical air purification and disinfection device.

[0022] In this specific embodiment, the filter body 102 is provided at the inner bottom of the housing 101, and the fixed base plate 103 is provided at the bottom of the filter body 102. The mounting box 104 is installed at the outer bottom of the housing 101, and a cover plate 112 is snapped onto the end face of the mounting box 104. The spring assembly is provided at the inner bottom of the mounting box 104, and a plurality of lifting columns 105 are provided on the upper surface of the spring assembly. The ends of the plurality of lifting columns 105 away from the spring assembly pass through the mounting box 104 and the housing 101 in sequence. Each lifting column 105 has a supporting plate 113 at one end located at the inner bottom of the housing 101. The supporting plate 113 abuts against the bottom of the fixed base plate 103. The side of the fixed base plate 103 is provided with a limit hole 114. The outer wall of the housing 101 is provided with... The filter screen body 102 is equipped with a plug-in locking post 106 that is compatible with the limiting locking hole 114. When the filter screen body 102 inside the housing 101 needs to be cleaned and maintained, the plug-in locking post 106 can be removed to disengage from the limiting locking hole 114. Under the reset action of the spring assembly, the lifting post 105 and the supporting plate 113 cooperate to apply force to the fixed base plate 103, thereby popping the filter screen body 102 out as a whole, which realizes the quick disassembly of the filter screen body 102. When the spring assembly needs to be replaced, the cover plate 112 can be removed to complete the disassembly and assembly of the spring assembly at the mounting box 104. Since the mounting box 104 is located outside the housing 101, the operation of replacing the spring assembly is more convenient.

[0023] The mounting base plate 107 is installed at the inner bottom of the mounting box 104. A plurality of reset springs are installed on the upper surface of the mounting base plate 107. The mounting top plate 108 is installed at the end of the plurality of reset springs away from the mounting base plate 107. The plurality of reset springs are installed between the mounting base plate 107 and the mounting top plate 108. The mounting base plate 107 facilitates the installation of the spring assembly inside the mounting box 104. The mounting top plate 108 facilitates the application of force to the fixed base plate 103 by the cooperation of the lifting column 105 and the supporting plate 113.

[0024] Secondly, the mounting base plate 107 is provided with a first disassembly handle 115 on the side facing the cover plate 112, and the cover plate 112 is provided with a second disassembly handle 116 on the side outside the mounting box 104. The second disassembly handle 116 facilitates the disassembly and assembly of the cover plate 112, and the first disassembly handle 115 facilitates the disassembly and assembly of the spring assembly.

[0025] Meanwhile, the spring body 109 is provided with a first mounting ring 110 and a second mounting ring 111 at both ends. The first mounting ring 110 is detachably connected to the mounting base plate 107, and the second mounting ring 111 is detachably connected to the mounting top plate 108. The installation of the reset spring is completed by setting the first mounting ring 110 and the second mounting ring 111.

[0026] Furthermore, the fixed base plate 103 is provided with two limiting holes 114 and two plug-in locking pins 106, with each plug-in locking pin 106 corresponding to one limiting hole 114. Since there are two limiting holes 114 and two plug-in locking pins 106, the structure is more stable when the fixed base plate 103 is fixed by the plug-in locking pins 106.

[0027] When using the quick-release structure of the filter screen in the medical air purification and disinfection device provided by this utility model, when it is necessary to clean and maintain the filter screen body 102 inside the housing 101, simply remove the plug-in locking post 106 so that the plug-in locking post 106 disengages from the limiting locking hole 114. Under the reset action of the spring assembly, the lifting post 105 and the supporting plate 113 cooperate to apply force to the fixed base plate 103, thereby popping out the filter screen body 102 as a whole, realizing the above-mentioned cleaning and maintenance. The filter body 102 can be quickly disassembled, and when the spring assembly needs to be replaced, the cover plate 112 can be removed to complete the disassembly and assembly of the spring assembly at the mounting box 104. Since the mounting box 104 is located outside the housing 101, the operation of replacing the spring assembly is more convenient. Furthermore, since there are two of each of the limiting clip holes 114 and the plug-in clips 106, the structure is more stable when the fixed base plate 103 is fixed by the plug-in clips 106.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
