Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of air filters, and particularly relates to a liquid tank type air filter. Background Art
[0002] An air filter is a device that captures dust from a gas-solid two-phase flow through the action of a porous filtering material and purifies the gas. It purifies the air with a low dust content and sends it into a room to meet the process requirements of a clean room and the air cleanliness in a general air-conditioned room.
[0003] Since the real consumable is the filter element in the liquid tank type air filter, rather than its shell, and each time it is replaced, the shell and the inner core need to be replaced together, resulting in a problem that the replacement of a conventional liquid tank type air filter is relatively wasteful of materials.
[0004] Therefore, we propose a liquid tank type air filter to solve the above problems. Summary of the Utility Model
[0005] The purpose of the utility model is to solve the problem that the replacement of a conventional liquid tank type air filter is relatively wasteful of materials, and to propose a liquid tank type air filter.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A liquid tank type air filter includes a first shell frame, a spring buckle and a second shell frame. One end of the spring buckle is fixedly connected to the first shell frame as a whole, and the other end of the spring buckle is buckled to the second shell frame. A first protection net is fixedly connected inside the first shell frame, and a second protection net is fixedly connected inside the second shell frame. When the filter element inside the first shell frame and the second shell frame needs to be replaced, the second shell frame is placed on the lower side, and then the spring buckle is pulled outwards to disengage the spring buckle from the second shell frame, so that the second shell frame slides down and disengages from the first shell frame, and then a new filter element is replaced. Compared with the existing liquid tank type air filter, the replacement waste rate is reduced.
[0008] Preferably, the first shell frame includes a first shell body, and a first buckle groove is formed on the side of the first shell body. After the first shell frame and the spring buckle are spliced, the first buckle groove is used to conveniently stabilize the docking position of the first shell frame and the spring buckle.
[0009] Preferably, the first shell frame further includes a first reinforcing strip, and the first reinforcing strip is fixedly connected inside the first shell body. The first reinforcing strip is used to increase the structural stability of the side of the first protection net.
[0010] Preferably, the snap buckle includes a spring piece, a first buckle block and a pull knob. The first buckle blocks are symmetrically and fixedly connected to the outside of the spring piece, and one end of the pull knob is fixedly connected to the spring piece. Pinch the pull knob by hand and then pull the pull knob outwards, so that the pull knob acts on the spring piece outwards, causing the spring piece to drive the first buckle block to disengage from the second housing frame, facilitating manual opening of the snap buckle.
[0011] Preferably, the second housing frame includes a second housing and a second buckle block. A second buckle groove is formed inside the second housing, and the second buckle block is fixedly connected to the side of the second housing. After the first housing frame and the second housing frame are spliced, the second buckle block is buckled in the first buckle groove to stabilize the up-and-down position of the first housing frame and the second housing frame. The first buckle block is engaged with the second buckle groove to stabilize the left-and-right position of the snap buckle and the second housing frame, facilitating the buckling of the first housing frame and the second housing frame.
[0012] Preferably, finger grooves are formed on the outside of the second housing frame. The pull knob can be conveniently manually buckled out through the finger grooves.
[0013] Preferably, the second housing frame further includes a second reinforcing strip, and the second reinforcing strip is fixedly connected to the inside of the second housing. The second reinforcing strip is used to increase the stability of the side structure of the second protective net.
[0014] In summary, the technical effects and advantages of the present utility model are as follows:
[0015] 1. When the filter element inside the first housing frame and the second housing frame needs to be replaced, place the second housing frame on the lower side, then pull the snap buckle outwards to disengage the snap buckle from the second housing frame, so that the second housing frame slides down and disengages from the first housing frame, and then replace the new filter element. Compared with the existing liquid tank type air filter, the replacement waste rate is reduced.
[0016] 2. Pinch the pull knob by hand and then pull the pull knob outwards, so that the pull knob acts on the spring piece outwards, causing the spring piece to drive the first buckle block to disengage from the second housing frame, facilitating manual opening of the snap buckle.
[0017] 3. After the first housing frame and the second housing frame are spliced, the second buckle block is buckled in the first buckle groove to stabilize the up-and-down position of the first housing frame and the second housing frame. The first buckle block is engaged with the second buckle groove to stabilize the left-and-right position of the snap buckle and the second housing frame, facilitating the buckling of the first housing frame and the second housing frame.
