[0029] The present invention will now be described in detail with reference to specific embodiments.

[0030] Example 1: As Figures 1 to 9 As shown, a tea cabinet with air exchange and filtration function includes a cabinet body 1 and an inner liner 2, with the inner liner located inside the cabinet. The inner liner has an air inlet 201 and an air outlet 202, both of which communicate with the outside. A filter element assembly 3 is installed at the air inlet, located inside the inner liner. An air inlet base 4 is connected to the inner liner at the corresponding location of the air inlet. The filter element assembly and the air inlet base 4 are detachably connected, either by a threaded connection or a snap-fit ​​connection. An air filter element 31 is installed inside the filter element assembly. A blower 5 is installed at the air outlet, and the blower is fixed to the inner liner by a blower bracket 51. Outside air enters the inner liner through the air inlet and the air filter element 31. Then, under the action of the blower, it exits to the outside through the air outlet.

[0031] A further improvement is that the filter element assembly includes a cylindrical sleeve 32 and a cover 33, with the air filter element 31 placed inside the sleeve 32, and the cover connected to one end of the sleeve.

[0032] Working principle: Equipped with an air inlet and outlet, the blower ventilates the inner liner. A filter assembly filters out impurities from the incoming fresh air, preventing dust or other contaminants from entering the inner liner. The filter assembly is replaceable, ensuring long-term airflow protection from impurities. After ventilation is complete, an indicator light on the door, controlled by the circuit board, displays a message indicating that ventilation has been completed.

[0033] Example 2: The characteristic of this example is that, as Figure 2 , Figure 3 , Figure 4 As shown, the inner liner is equipped with an inner liner decorative panel 6, and the inner liner decorative panel has mounting holes 61 at the corresponding positions of the filter element assembly. The filter element assembly extends to the mounting holes, and the air intake base 4 is located between the inner liner decorative panel and the inner liner wall. This improves the appearance of the inner liner and makes it convenient to replace the filter element assembly through the mounting holes.

[0034] The rest can be the same as in Example 1.

[0035] Example 3: The characteristic of this example is that, as Figure 6 , Figure 7 , Figure 8 As shown,

[0036] The cover 33 is provided with a buckle 331, and the sleeve 32 is provided with a slot 321. The buckle is placed in the slot, and the cover and the sleeve are connected at one end through the buckle and the slot.

[0037] An activated carbon box 34 is provided inside the sleeve 32. The activated carbon box can increase the ability to filter air and absorb odors.

[0038] The rest can be the same as in Example 2.

[0039] Example 4: The characteristic of this example is that, as Figure 7 , Figure 8 , Figure 10 As shown, the sleeve is equipped with a magnet 7, which is placed in a magnet slot 71 on the sleeve 32. A magnetic control switch 72 is provided on the air intake base 4. The magnetic control switch is electrically connected to the control circuit board, and the control circuit board is electrically connected to the alarm indicator. Of course, the magnet can be placed on other parts of the filter element assembly, as long as its magnetic force can interact with the magnetic control switch.

[0040] The alarm indicator is a light installed on the door, with a corresponding indicator symbol 73 on the door. The control circuit board has a control module that calculates the usage time of the air filter assembly. After the air filter assembly is installed in the air intake base, the magnet acts on the magnetic switch (causing it to be in a closed or open state, depending on the design requirements). The module on the control circuit board then starts calculating the time. When the designed usage time of the air filter is reached, the alarm indicator (light) is activated to remind people to replace the air filter assembly, such as by displaying a yellow light.

[0041] The control circuit board is electrically connected to the position status indicator light of the filter assembly. In this example, the position status indicator light is white. After the filter assembly is installed on the air intake base, the magnet acts on the magnetic switch, illuminating the position status indicator light and indicating that the filter assembly is in operation. When the filter assembly is removed, the alarm indicator (indicator light) illuminates.

[0042] The rest can be the same as in Example 2 or Example 3.

[0043] Example 5: The feature of this example is that the air intake base is an air intake pump base. An air intake pump is installed inside the air intake pump base. The air intake pump can be used to enhance the air intake capacity. The rest is the same as the examples above.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
