Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a drying and filtering device that is easy to replace. Background Technology

[0002] With the continuous development of society, people's demands for hygiene, environment, and health are becoming increasingly urgent. Food purifiers have been widely used to remove pesticide residues from fruits and vegetables and hormones from meat. Existing food purifiers generally include a main unit and a generating module. The main unit generates ozone and supplies it to the generating module, which is immersed in water to mix the ozone with the water to form ozone water for purifying food.

[0003] Currently, the ozone generated by the main unit of existing food purifiers is generally converted from oxygen in the air. The dryness of the air not only significantly affects the concentration and yield of ozone gas, but also affects the service life of the ozone generator. Therefore, existing food purifiers have a drying and filtering device between the air pump and the ozone generator for drying and filtering the air. However, the drying filter in the device is a consumable and needs to be replaced frequently to ensure the drying and filtering effect. Therefore, it is necessary to design a drying and filtering device that makes it easy to replace the drying filter. Utility Model Content

[0004] The present invention aims to overcome the defects in the prior art and provide a dry filter device that is easy to replace. The dry filter is inserted into the sealing plug in the second chamber through the air outlet connector, and with the pressing action of the pressure rib on the detachable cover, the dry filter is securely installed in the first chamber, thereby achieving the purpose of easy replacement of the dry filter by removing the cover.

[0005] To achieve the above objectives, this utility model provides an easy-to-replace drying and filtering device, which is installed on the main unit of the food purifier for drying and filtering the intake air;

[0006] The device includes a box body, a box cover, a drying filter, and a sealing plug. The box body is configured with a first chamber and a second chamber adjacent to the first chamber. A communication hole is provided on a first side wall shared by the first chamber and the second chamber. A connector is provided on a second side wall in the second chamber opposite to the first side wall.

[0007] The sealing plug is embedded in the second cavity and is at least sealed between the first side wall and the second side wall. The sealing plug is provided with a communication channel connecting the communication hole and the connector.

[0008] The drying filter has an air inlet connector and an air outlet connector. The drying filter is embedded in the first chamber and its air outlet connector extends into the through hole of the sealing plug through a connecting hole and is sealed to it.

[0009] The lid is detachably fitted at the opening of the first chamber, and the inner surface of the lid is provided with a pressing rib for pressing against the dryer filter to fix it in the first chamber.

[0010] The first chamber is further configured such that a socket is provided on one end face corresponding to its opening and a latch is provided on the other side.

[0023] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0024] This utility model provides an easy-to-replace drying and filtering device, such as... Figure 1 and Figure 2 As shown, the device includes a box body 1, a box cover 2, a dryer filter 3, and a sealing plug 4. The box body 1 is a thin shell structure with an open upper end and its inner cavity is a first chamber 11. The box body 1 has a second chamber 12 with an open lower end, which is provided on the outer structure of the first side wall. The box cover 2 is detachably closed at the opening of the first chamber 11. The dryer filter 3 is embedded in the first chamber 11 and is constrained between the box body 1 and the box cover 2. The sealing plug 4 is embedded in the second chamber 12.

[0025] In this embodiment, as Figure 2 and Figure 3 As shown, a through-hole 111 is provided on the first side wall shared by the first chamber 11 and the second chamber 12. A connector 121 communicating with the inner cavity of the second chamber 12 is provided on the second side wall opposite to the first side wall. The connector 121 is used to connect to the inlet of the ozone generator through a pipeline. A sealing plug 4 is fitted into the second chamber 12 and is at least sealed between the first and second side walls. The sealing plug 4 is provided with a connecting channel 41 connecting the through-hole 111 and the connector 121. Preferably, the sealing plug 4 and the second chamber 12 are rectangular structures with matching shapes and sizes. The dryer filter 3 has an air inlet connector 31 and an outlet connector 32. The air connector 32 is filled with desiccant 33. The dryer filter 3 is placed on the bottom of the first chamber 11. The air inlet connector 31 of the dryer filter 3 is connected to the air pump, and its air outlet connector 32 is inserted into the connecting channel 41 of the sealing plug 4 and sealed to it. This makes the dryer filter 3 and the connector 121 sealed and connected. At the same time, the sealing plug 4 can restrain the dryer filter 3 to limit its movement. The lid 2 is detachably closed at the opening of the first chamber 11. The inner surface of the lid 2 is provided with a raised pressing rib 21. The pressing rib 21 is used to press against the filter dryer to clamp and fix it between the box body 1 and the lid 2.

[0026] In this embodiment, as Figure 3 and Figure 4 As shown, the box body 1 has an insertion port 13 on one side of the opening of the first chamber 11 and a latch 14 on the other side. The box cover 2 has a pin 22 on one side and a U-shaped spring 23 on the other side. The U-shaped spring 23 has a latch 231 on the side wall facing the latch 14. The box cover 2 inserts the pin 22 into the insertion port 13 of the box body 1 and latches the latch 14 into the latch 231. This allows the box cover 2 to be stably closed on the box body 1. At the same time, by moving the U-shaped spring 23, the latch 14 can be disengaged from the latch 231 to facilitate the disassembly of the box cover 2.

[0027] In this embodiment, a limiting rib 112 is provided on the first side wall of the first chamber 11, and a limiting protrusion 113 for constraining the dryer filter 3 is provided on the other set of opposite side walls of the first chamber 11, which are different from the first side wall. This design can better limit and constrain the dryer filter 3 within the box 1.

[0028] In this embodiment, as Figure 5 As shown, the drying and filtering device 10 is installed on the bottom of the main unit 100 of the food purifier; specifically, the bottom of the main unit 100 has a recessed mounting port with a countersunk structure, and the box body 1 is embedded in the mounting port with the first chamber 11 facing downward, so that the box cover 2 can be exposed outside the main unit 100 and closed on the box body 1, thus making it easy to directly remove the box cover 2 to replace the drying filter 3.

[0029] Compared with the prior art, this utility model has a simple and reasonable structure. The sealing plug is embedded in the second chamber of the box body, and the dryer filter is embedded in the first chamber of the box body with its air outlet inserted into the sealing plug. In this way, the sealing plug limits and constrains the dryer filter, and also forms a sealed connection between the dryer filter and the box body. At the same time, the pressure of the pressure rib on the detachable box cover can make the dryer filter firmly installed in the box body, thereby achieving the purpose of easy replacement of the dryer filter by removing the box cover.

[0030] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
