Description

Technical Field

[0001] This utility model relates to a top-fill air purifier with a water purification structure. Background Technology

[0002] Humidifiers typically consist of a blower, a water tank, and a filter assembly. They deliver humidified, clean airflow into the room by wetting the filter assembly and blowing air into it. A common wetting method involves immersing the lower end of the filter assembly in the water tank to allow it to absorb water. However, due to gravity and the filter's absorption capacity, wetting is uneven, often resulting in the lower end of the filter assembly being wet while the upper end remains dry, leading to poor wetting efficiency. Furthermore, to ensure proper wetting of the filter assembly, the water level in the tank needs to be maintained constantly, or the filter assembly needs to be made longer so that its lower end extends to the bottom of the tank. Clearly, such solutions are expensive in terms of both water replenishment and filter assembly costs, and are not environmentally friendly or energy-efficient.

[0003] In reality, we only need to keep the filter element moist. The amount of water needed to moisten it is small, so a water pump can be used to draw water from the tank to the top of the filter element, wetting it from top to bottom. Furthermore, if the water quality is poor, scale may accumulate, or foreign objects such as hair or sand may fall into the water. If these are sucked into the water pump, they will cause blockages and may even lead to pump failure. Utility Model Content

[0004] This utility model proposes a top-fill water air purifier with a water purification structure, aiming to prevent water pump blockage and extend water pump lifespan. The specific technical means adopted are as follows:

[0005] A top-fill air purifier with a water purification structure includes a housing. Inside the housing, a blower mechanism, a filter module, and a water tank are arranged from top to bottom. A water collection tray is provided at the top of the housing, and the water collection tray communicates with the water tank via a water inlet channel. The filter module includes a filter support and a cylindrical filter. The upper part of the filter support has an annular water channel, and the bottom of the annular water channel has multiple drainage holes facing the top of the cylindrical filter. The top of the water tank has a water collection trough, and the water collection trough has a return port communicating with the water tank. Inside the water tank, there is a water pump, a water pump protection box, and a water inlet pipe for connecting the water pump and the annular water channel. The water pump protection box has an adjacent and interconnected first chamber and a second chamber. The first chamber has a water inlet and a purification component is installed inside the first chamber, and the water pump is installed in the second chamber.

[0006] In one or more embodiments of the present invention, the purification component includes a purification box filled with purification contents, the purification contents including a descaling agent.

[0007] In one or more embodiments of this utility model, the bottom of the first chamber is provided with an insertion port, and the purification box is inserted into and placed into the first chamber through the insertion port; the first chamber and the second chamber are separated by a perforated partition, and the water inlet is located on the other side of the chamber wall opposite to the partition.

[0008] In one or more embodiments of this utility model, the side of the purification box is provided with a snap fastener, the inner wall of the first chamber is provided with a snap hole that cooperates with the snap fastener for positioning, and notches are provided on the cavity walls on both sides of the insertion port. After the purification box is installed into the first chamber, the insertion port is closed by the bottom plate of the purification box.

[0009] In one or more embodiments of this utility model, the bottom of the purification box has an opening, and an annular groove is provided on the edge of the opening. The opening is closed by a bottom plate. The bottom plate is provided with an annular rib adapted to the annular groove. The annular rib is aligned with the annular groove and embedded to fix the bottom plate to the bottom of the purification box.

[0020] The following is in conjunction with the appendix Figures 1 to 8 The following is a further description of the proposed solution:

[0021] This utility model discloses a top-fill air purifier with a water purification structure, comprising a housing 1. Inside the housing 1, arranged from top to bottom, are a blower mechanism 2, a filter module 3, and a water tank 4. A water collection tray 11 is located at the top of the housing 1, and the water collection tray 11 communicates with the water tank 4 via a water inlet channel 5. The filter module 3 includes a filter support 31 and a cylindrical filter element 32. The filter support 31 has an annular water channel 6 at its upper part, and the bottom of the annular water channel 6 has multiple drains directly opposite the top of the cylindrical filter element 32. The top of the water storage tank 4 is provided with a water collection trough 7, and the water collection trough 7 is provided with a return port 71 connected to the water storage tank 4. The water storage tank 4 is provided with a water pump 8, a water pump protection box 9, and a water inlet pipe 10 for connecting the water pump 8 and the annular water channel 6. The water pump protection box 9 is provided with an adjacent and connected first chamber 901 and a second chamber 902. The first chamber 901 is provided with a water inlet 91 and a purification component is installed in the first chamber 901. The water pump 8 is installed in the second chamber 902.

[0022] The purification assembly includes a purification box 92 filled with purification contents, including a descaling agent, and optionally, a fragrance. The bottom of the purification box 92 has an opening with an annular groove 921 along its rim. This opening is closed by a base plate 93. The base plate 93 has an annular rib 931 that mates with the annular groove 921. Aligning the annular rib 931 with the groove 921 and embedding it secures the base plate 93 to the bottom of the purification box 92. When the purification contents need to be replaced, simply lifting the base plate 93 reveals the internal filling space of the purification box 92. This not only facilitates users in adding or replacing purification contents but also allows manufacturers to create filter cartridges with different functions by filling them with different purification contents during production.

[0023] In terms of the installation structure of the purification box 92, this product adopts an overall quick-release and quick-installation design. An insertion port 94 is provided at the bottom of the first chamber 901, through which the purification box 92 is inserted and placed into the first chamber 901. The first chamber 901 and the second chamber 902 are separated by a perforated partition 903, and the water inlet 91 is located on the opposite side wall of the partition 903. A spring-loaded buckle 922 is provided on the side of the purification box 92, and a buckle hole 904 is provided on the inner wall of the first chamber 901 to engage and limit the spring-loaded buckle 922.

[0024] When the purification box 92 is inserted into the first chamber 901, the snap fastener 922 moves along with the box towards the snap hole 904 until it snaps into the snap hole 904, thus securing it. After the purification box 92 is inserted into the first chamber 901, the insertion opening 94 is closed by the bottom plate 93 of the purification box 92. Notches 95 are provided on the cavity walls on both sides of the insertion opening 94, exposing the side of the purification box 92 inserted into the first chamber 901. The user only needs to apply force at the notches 95 to clamp the purification box 92 and pull it out.

[0025] Furthermore, the first chamber 901 is also equipped with a coarse filter plate 96 with filter holes. The coarse filter plate 96 is set close to the partition 903 and is used to filter larger particles, hair, etc. in the water. Specifically, the top edge of the coarse filter plate 96 is provided with a locking block 961, and the bottom edge of the coarse filter plate 96 is provided with a buckle 962. The coarse filter plate 96 enters through the insertion port 94 and slides upward along the partition 903 until the locking block 961 is embedded in the locking hole 97 located at the top of the first chamber 901, and at the same time, the buckle 962 is embedded in the locking groove 98 located at the bottom of the partition 903 for engagement. The locking block 961 and the buckle 962 restrict the horizontal displacement of the coarse filter plate 96, and the bottom plate 93 of the purification box 92 prevents the coarse filter plate 96 from being pulled out.

[0026] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
