Description

Technical Field

[0001] This utility model relates to the field of air treatment technology, and in particular to a filter unit for an air treatment device. Background Technology

[0002] Air handling equipment is a device that uses porous filter materials to capture dust from a gas-solid two-phase flow and purify the gas. It purifies the air with low dust content and then sends it into the room to ensure the process requirements of clean rooms and the air cleanliness of general air-conditioned rooms. Its internal air filter unit is an important component of the equipment.

[0003] A search revealed that utility model patent CN221906254U discloses a high-efficiency air filtration unit, including a filter ventilation duct. An installation mechanism is fixedly connected to the left side of the filter ventilation duct, and a filter fabric is fixedly connected inside the installation mechanism. The installation mechanism includes a mounting bottom ring, which is fixedly connected to the left end of the filter ventilation duct. A spring is fixedly connected inside the mounting bottom ring, and a limit block is fixedly connected to one end of the spring. A retaining strip is fixedly connected to the top of the limit block, and a connecting strip is fixedly connected to the right end of the limit block. An adjusting ring is fixedly connected to the right end of the connecting strip, and a slip ring is fixedly connected to the left side of the adjusting ring.

[0004] Although the air filter unit described above can remove and clean the filter fabric, the actual removal of the filter fabric requires not only rotating the adjusting ring, but also manually disassembling the outer casing ring seat and emptying the filter fabric from the inside of the outer casing ring seat. The operation is quite cumbersome. In addition, the removed outer casing ring seat is not easy to store and is prone to being lost.

[0005] Therefore, it is necessary to invent a filter unit for an air handling device to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a filter unit for an air handling device that allows for more convenient disassembly and cleaning of the filter fabric. The integrated rotary mounting mechanism and filter ventilation pipe prevent parts from being lost due to lack of storage, making it more convenient in actual use. This addresses the problem mentioned in the background art, where disassembling the filter fabric requires not only rotating the adjusting ring but also manually removing the outer casing ring seat and emptying the filter fabric from the inside of the outer casing ring seat, making the operation cumbersome. Furthermore, the removed outer casing ring seat is difficult to store and prone to loss.

[0007] According to one aspect of this disclosure, a technical solution is provided as follows: a filter unit for an air handling device, comprising:

[0008] A filter ventilation duct, which is used to connect to the air inlet of an air handling unit;

[0009] A rotary mounting mechanism, comprising a sealing ring, a movable tube, an arc-shaped mounting plate, and anti-slip protrusions;

[0010] A sealing ring is nested at the inner edge of the sealing ring. The movable tube is rotatably mounted on the inner side of the sealing ring via a bearing. Multiple anti-slip ridges are provided. The multiple anti-slip ridges are evenly and fixedly mounted on the outer side of the movable tube at the end away from the sealing ring. The arc-shaped mounting plate is fixedly mounted on the end of the movable tube near the filter ventilation tube and located directly below the filter fabric.

[0011] A connection reset mechanism is used to connect the filter ventilation duct and the rotary mounting mechanism; and

[0012] A filter fabric used for filtering air.

[0013] According to at least one embodiment of the air handling apparatus of the present disclosure, the filter ventilation duct includes a duct body and a pressure ring, wherein the pressure ring is fixedly disposed inside the duct body.

[0014] According to at least one embodiment of the air handling equipment of the present disclosure, the filter unit of the air handling equipment is provided with two sets of connection reset mechanisms, and the two sets of connection reset mechanisms are respectively located on both sides of the filter ventilation pipe.

[0015] According to at least one embodiment of the air handling device filter unit of the present disclosure, the connection reset mechanism includes a first ear plate and a second ear plate, the first ear plate being fixedly disposed on the side of the tube body, and the second ear plate being fixedly disposed on the side of the sealing ring.

[0016] According to at least one embodiment of the air handling device filter unit of the present disclosure, the connection reset mechanism further includes a sliding pin and a reset spring. The sliding pin slides through the first ear plate and is fixedly connected to the second ear plate. The reset spring is sleeved on the outside of the sliding pin and fixedly connected between the first ear plate and the sliding pin.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] This invention features a rotary mounting mechanism that facilitates the disassembly and cleaning of the filter fabric. Anti-slip protrusions pull the movable tube, causing the sealing ring to move forward. As the sealing ring moves forward, the arc-shaped mounting plate moves the filter fabric forward synchronously until it exits the tube. The anti-slip protrusions then rotate the movable tube, causing the arc-shaped mounting plate to rotate synchronously until its opening faces downwards. At this point, the filter fabric inside the arc-shaped mounting plate falls downwards due to gravity, thus detaching. The anti-slip protrusions are then released, and the rotary mounting mechanism resets under the action of a resetting mechanism. Compared to existing products of the same type, this invention allows for more convenient disassembly and cleaning of the filter fabric. Furthermore, the integrated rotary mounting mechanism and filter ventilation tube prevent parts from being lost due to lack of storage, making it more convenient in actual use.

[0028] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., as in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0029] Figure 1 This is a schematic diagram of the overall structure of the filter unit of an air handling device according to one embodiment of the present disclosure.

[0030] Figure 2 This is a partial structural diagram of the rotary mounting mechanism 2 and the connection and reset mechanism 3 of the filter unit of an air handling device according to one embodiment of the present disclosure.

[0031] Figure 3 This is a partial structural schematic diagram of the rotary mounting mechanism 2 of the filter unit of an air handling device according to one embodiment of the present disclosure.

[0032] like Figures 1-3 As shown, the filtration unit of the air handling equipment disclosed herein may include components such as: a filter ventilation duct 1, a rotary mounting mechanism 2, a connection and reset mechanism 3, and a filter fabric 4.

[0033] like Figure 2 As shown, in a preferred embodiment, the filter ventilation pipe 1 includes a pipe body 11 and a pressure ring 12, wherein the pressure ring 12 is fixedly disposed on the inner side of the pipe body 11.

[0034] Therefore, after the filter fabric 4 is installed, the pressure ring 12, in conjunction with the movable tube 22 on the rear side of the filter fabric 4, presses the filter fabric 4 tightly, thereby ensuring that the filter fabric 4 can perform its filtering function normally.

[0035] like Figure 2 and Figure 3As shown in this disclosure, the rotary mounting mechanism 2 includes a sealing ring 21, a movable tube 22, an arc-shaped mounting plate 23, and anti-slip ridges 24. A sealing ring is nested at the inner edge of the sealing ring 21. The movable tube 22 is rotatably mounted inside the sealing ring 21 via a bearing. Multiple anti-slip ridges 24 are provided and are evenly fixedly mounted on the outer side of the movable tube 22 away from the sealing ring 21. The arc-shaped mounting plate 23 is fixedly mounted on the end of the movable tube 22 near the filter ventilation tube 1 and located directly below the filter fabric 4.

[0036] Therefore, when disassembling and cleaning the filter fabric 4, the movable tube 22 is pulled by the anti-slip protrusion 24. After the movable tube 22 is pulled, the sealing ring 21 moves forward. When the sealing ring 21 moves forward, the filter fabric 4 moves forward synchronously through the arc-shaped mounting plate 23 until the filter fabric 4 is removed from the inside of the tube body 11. Then, the movable tube 22 is rotated by the anti-slip protrusion 24. When the movable tube 22 rotates, the arc-shaped mounting plate 23 rotates synchronously until the arc-shaped mounting plate 23 rotates to the point where the opening faces downward. At this time, the filter fabric 4 located inside the arc-shaped mounting plate 23 falls downward due to gravity and is thus removed. Then, the anti-slip protrusion 24 is released. At this time, the rotary mounting mechanism 2 is reset by the connecting reset mechanism 3. Compared with existing similar products, the disassembly and cleaning of the filter fabric 4 can be completed more conveniently. At the same time, the rotary mounting mechanism 2 and the filter ventilation tube 1 are integrated, which can avoid the situation where parts are lost due to lack of storage, making it more convenient in actual use.

[0037] like Figure 2 As shown, in a preferred embodiment, the connection reset mechanism 3 is provided in two sets, with the two sets of connection reset mechanisms 3 located on both sides of the filter ventilation pipe 1 respectively. The connection reset mechanism 3 includes a first ear plate 31, a sliding pin 32, a reset spring 33, and a second ear plate 34. The first ear plate 31 is fixedly disposed on the side of the pipe body 11, and the second ear plate 34 is fixedly disposed on the side of the sealing ring 21. The sliding pin 32 slides through the first ear plate 31 and is fixedly connected to the second ear plate 34. The reset spring 33 is sleeved on the outside of the sliding pin 32 and fixedly connected between the first ear plate 31 and the sliding pin 32.

[0038] Therefore, when the sealing ring 21 moves forward, it drives the second ear plate 34 to move forward synchronously. When the second ear plate 34 moves forward, it drives the sliding pin 32 to move forward synchronously. When the sliding pin 32 moves forward, it compresses the return spring 33. Subsequently, when the second ear plate 34 is no longer pulled, the compressed return spring 33 drives the second ear plate 34 to return to its original position through the sliding pin 32, thereby causing the rotary mounting mechanism 2 to return to its original position synchronously.

[0039] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0040] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
