Description

Technical Field

[0001] The utility model belongs to the technical field of air filtration, and particularly relates to a heat pump air cleaning and filtering device. Background Art

[0002] The reason for the unstable filtration efficiency is that the characteristics and concentration changes of different types of particles floating in the air make it difficult for the filter to maintain a uniform capture effect during use, especially when the load is high or the pollutant concentration increases sharply, the filter efficiency will drop significantly. Secondly, the high energy consumption is mainly related to the operation mode of the air filter device, especially mechanical filters under high wind speed or high load, which often require greater energy input to maintain air circulation, which further increases operating costs. Due to the difficulty of maintenance, existing filter devices usually need to regularly check and replace filter materials. This process is not only time-consuming and labor-intensive, but some complex equipment requires professional maintenance, which increases labor costs and technical requirements.

[0003] Conventional solutions include regularly replacing filter media, increasing fan power to increase flow, and optimizing design to improve airflow distribution. However, these methods also have drawbacks in practical applications. For example, although regularly replacing filter media can effectively improve filtering effects, it will increase operating costs and management burdens, and in some environments, frequent replacement is not easy to implement. Therefore, we hope to design an air cleaning filter device with a new structure to solve this problem. Utility Model Content

[0025] A receiving member 150 for receiving debris is fixed at the lower end of the housing 110 . The cleaning component 200 includes a brush plate 1 210 and a brush plate 240 for cleaning the internal structure of the filter component 100 . The brush plate 1 210 and the brush plate 240 are fixedly connected via a connecting plate 220 .

[0026] See also Figures 1 to 3 The filter assembly 100 also includes a filter plate 120 and a filter plate 2 160 for filtering air, and the filter plate 120 is installed inside the front side of the housing 110.

[0027] The filter assembly 100 further includes a reducer 130 for accelerating the air flow rate. The reducer 130 is fixed to the rear end of the housing 110 , and a filter plate 2 160 is installed inside the front end of the reducer 130 .

[0028] The rear end of the housing 110 is connected to the interior of the front end of the reducer 130 , the filter plate 120 is placed in front of the filter plate 2 160 , and a connecting pipe 140 for connecting to an external air intake pipe is fixed to the rear end of the reducer 130 .

[0029] The receiving part 150 includes a waste box 151 and a mounting plate 152. A mounting plate 152 for fixing is welded to the front and rear sides of the upper end of the waste box 151 respectively. The waste box 151 is sealed and fixedly connected to the lower end of the outer shell 110 through the mounting plate 152 and a rubber sealing gasket. The upper side of the waste box 151 is connected to the lower end of the outer shell 110. The setting of the receiving box can receive and collect the waste residue cleaned by the cleaning component 200.

[0030] The waste box 151 is placed below the filter plate 1 120 and the filter plate 2 160 . The rear end of the filter plate 120 extends to 2 cm above the front end of the waste box 151 , and the front end of the filter plate 2 160 extends to 2 cm above the rear end of the waste box 151 .

[0031] As the first embodiment of the utility model, a receiving member 150 is provided at the lower end of the outer shell 110. In actual use, when the cleaning component 200 cleans the dust on the filter plate 120 and the filter plate 160, the cleaned dust gradually falls into the waste box 151 under the action of gravity, and is collected in the waste box 151. Then the user removes the waste box 151 to complete the cleaning of the waste, thereby preventing the cleaned dust from falling into the inner part of the outer shell 110 and causing the filter plate 120 and the filter plate 160 to be blocked again, and facilitating the disposal of the cleaned dust.

[0032] See also Figures 1 to 3 A guide rod is respectively provided on the left and right sides of the shell 110, and a compression spring is installed at the lower end of each guide rod. The natural height of the compression spring is four-fifths of the internal height of the shell 110. The setting of the guide rod, in conjunction with the compression spring, can guide the cleaning component 200 and enable the cleaning component 200 to be located on the upper side of the shell 110 when no external force is applied, so as to avoid affecting the air flow.

[0033] The cleaning assembly 200 also includes a guide plate and a push-pull rod 230. The middle of the upper end of the connecting plate 220 is welded and fixed to the lower end of the push-pull rod 230. A guide plate is welded on the left and right sides between the brush plate 1 210 and the brush plate 2 240 respectively. The two guide plates are slidably connected to the two guide rods inside the outer shell 110, and the two guide plates are movably abutted against the upper ends of the two compression springs.

[0034] As a second embodiment of the present invention, based on the above-mentioned first embodiment, by setting a cleaning assembly 200, in actual use, if it is necessary to clean filter plate 120 and filter plate 2 160, since the two guide plates are slidably connected to the two guide rods inside the housing 110, and the two guide plates are movably abutted against the upper ends of the two compression springs, the setting of the guide rods, in conjunction with the compression springs, can guide the cleaning assembly 200, and can make the cleaning assembly 200 be located on the upper side of the housing 110 when no external force is applied, so as to avoid affecting the air flow rate. The user presses the entire cleaning assembly 200 downward through the push-pull rod 230. In this process, the brush plate 1 210 brushes the rear side of the filter plate 120, and the brush Plate 240 brushes the front side of filter plate 2 160 (filter plate 2 160 is thinner, so that the bristles on brush plate 240 clean filter plate 2 160 and take care of its rear side to prevent dust from being continuously hidden on filter plate 2 160). When brush plate 240 and brush plate 1 210 reach the bottom of housing 110, push-pull rod 230 is released, and the entire cleaning assembly 200 is pushed up by the action of compression spring. Such reciprocating motion can remove the dust attached to filter plate 1 120 and filter plate 2 160, thereby solving the problem of reduced power efficiency of filter assembly 100 caused by continuous attachment of impurities in the air, and helping to keep filter assembly 100 in a more efficient filtering processing state.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
