Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning, specifically to an air filter for heating, ventilation and air conditioning that is easy to install and remove. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) are air conditioning systems that provide heating, ventilation, and air conditioning. Since the main functions of HVAC include these three aspects, the primary function of an HVAC system is to control parameters such as air temperature, humidity, cleanliness, and airflow speed to meet the requirements of production and daily life, and improve occupational health conditions. HVAC systems play a vital role in modern large-scale buildings, not only providing a comfortable indoor environment but also enhancing indoor comfort by controlling air temperature and humidity.

[0003] However, the installation and removal of HVAC filters usually require the removal of the air outlet grille, which takes a considerable amount of time. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an easy-to-disassemble air filter for HVAC, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: an easy-to-install and disassemble air filter for HVAC, including an HVAC outlet pipe, a filter installation compartment installed on one side of the HVAC outlet pipe, a filter installed inside the filter installation compartment, a limiting groove formed on the inner side wall of the filter installation compartment, an installation block installed on the outer side of the filter corresponding to the limiting groove, a limiting insert block installed on the upper surface of the filter, an elastic retaining bead installed on the outer side of the limiting insert block, a positioning slot formed above the limiting insert block corresponding to the inner side of the limiting groove, and a lifting ring installed on one side of the limiting insert block on the upper surface of the filter.

[0006] As a further embodiment of this utility model: a take-up roller is installed on the upper surface of the filter installation chamber, an elastic rotating shaft is connected between the take-up roller and the filter installation chamber, and a lifting rope is connected between the outer side of the take-up roller and the lifting ring.

[0007] As a further improvement of this utility model: an air outlet grille is installed on the side end of the HVAC outlet pipe near the filter installation compartment, and a handle is installed on the lower surface of the filter.

[0008] As a further improvement of this utility model: the limiting plug is engaged with the positioning slot, and the filter is slidably connected to the limiting groove through the mounting block.

[0009] As a further improvement of this utility model, the lifting ring is fixedly connected to the filter.

[0010] As a further improvement of this utility model: the air vent grille is fixedly connected to the HVAC air vent pipe by bolts, and the handle is fixedly connected to the filter.

[0011] As a further improvement of this utility model, the lifting rope is fixedly connected to the winding roller and the lifting ring.

[0012] As a further improvement of this utility model, the mounting block is fixedly connected to the filter.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The filter installation compartment is for installing the filter. After the filter as a whole is installed by the mounting block on the outer section corresponding to the inside of the limiting groove, and the limiting insert is aligned with the position of the positioning slot, the elastic retaining ball is squeezed and contracted, thus limiting the filter as a whole inside the filter installation compartment.

[0015] When replacement is needed, the entire filter is pulled out of the filter installation compartment by pulling down the handle. After removing the lifting rope and the lifting ring at the top of the filter, the lifting rope is connected to the new filter for quick installation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5 As shown, this embodiment provides an easy-to-install and disassemble air filter for HVAC systems, including an HVAC outlet pipe 1. A filter installation chamber 3 is installed on one side of the HVAC outlet pipe 1. A filter 5 is installed inside the filter installation chamber 3. A limiting groove 301 is formed on the inner side wall of the filter installation chamber 3. An installation block 502 is installed on the outer side of the filter 5 corresponding to the limiting groove 301. The filter 5 is slidably connected to the limiting groove 301 through the installation block 502. The installation block 502 is fixedly connected to the filter 5. A limiting insert 504 is installed on the upper surface of the filter 5. An elastic retaining bead 505 is installed on the outer side of the limiting insert 504. A positioning slot 302 is formed on the upper side of the limiting insert 504 corresponding to the inner side of the limiting groove 301. The limiting insert 504 is engaged with the positioning slot 302. A lifting ring 503 is installed on one side of the limiting insert 504 on the upper surface of the filter 5. The lifting ring 503 is fixedly connected to the filter 5.

[0024] like Figure 2-5 As shown, in this embodiment, a take-up roller 4 is installed on the upper surface of the filter installation chamber 3. An elastic rotating shaft 401 is connected between the take-up roller 4 and the filter installation chamber 3. A lifting rope 402 is connected between the outer side of the take-up roller 4 and the lifting ring 503. The lifting rope 402 is fixedly connected to the take-up roller 4 and the lifting ring 503. An air outlet grille 2 is installed on the side end of the HVAC outlet pipe 1 near the filter installation chamber 3. The air outlet grille 2 is fixedly connected to the HVAC outlet pipe 1 by bolts. A handle 501 is installed on the lower surface of the filter 5. The handle 501 is fixedly connected to the filter 5.

[0025] The working principle of this utility model is as follows: During use, a filter installation chamber 3 is provided at the end of the HVAC outlet pipe 1. The filter installation chamber 3 is for installing the filter 5. During installation, after the outlet grille 2 is installed at the outlet end of the HVAC outlet pipe 1, the suspension rope 402 is pulled downwards and then tied to the lifting ring 503 at the upper end of the winding roller 4. After the filter 5 passes through the outer section of the installation clip 502 and aligns with the limiting groove 301, the suspension rope 402 is wound up under the resetting action of the elastic rotating shaft 401, thus pushing the filter 5 into the filter installation chamber 3. Internally, after the limiting insert 504 is positioned in the positioning slot 302, the filter 5 is pushed upwards, causing the elastic retaining ball 505 to be compressed and contracted, thus limiting the filter 5 inside the filter installation chamber 3. When replacement is required, the filter 5 is pulled out of the filter installation chamber 3 by pulling down the handle 501. The lifting rope 402 wound on the upper end of the take-up roller 4 is then pulled out. After the lifting rope 402 and the lifting ring 503 at the upper end of the filter 5 are disassembled, the lifting rope 402 is connected to the new filter 5 for quick installation.
