Description

Technical Field

[0001] The invention relates to a filter, in particular to a top water inlet external pressure filter used in conjunction with scale-inhibiting filter material. Background Art

[0002] The filter in the prior art includes: an upper cover assembly and a tank body connected to the upper cover assembly, wherein a filter element structure is arranged in the tank body. The filter element structure alone can only filter particulate impurities in raw water, but cannot fundamentally prevent the formation of scale.

[0003] However, some water-using occasions require further anti-scaling treatment, so we need to add anti-scaling filter materials. After adding anti-scaling filter materials, on the one hand, it is necessary to control the water flow to penetrate the anti-scaling filter materials for efficient anti-scaling treatment. Secondly, the raw water channel and the purified water channel must be effectively separated to improve the water purification reliability of the filter. In addition, the filter element structure needs to be easy to maintain and replace. The present invention aims to solve this technical problem. Summary of the invention

[0004] One of the purposes of the present invention is to solve the deficiencies of the prior art and provide a top water inlet external pressure filter. The tank body and the upper cover assembly adopt a detachable quick-disassembly and quick-installation design, which is convenient for maintenance and replacement. Secondly, the water flow can penetrate the scale-inhibiting filter material to fully prevent scale. In addition, the raw water channel and the purified water channel are fully independent and do not interfere with each other, and the water purification reliability is high.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] The top water inlet external pressure filter includes an upper cover assembly and a tank body. The upper cover assembly includes an upper cover body and an inner cover. The upper cover assembly is provided with a water inlet on the top and a water outlet on the side. The upper cover assembly and the tank body are detachably connected. A filter cavity is formed between the inner cover and the tank body. A filter element structure is provided in the filter cavity:

[0007] The filter element structure includes a filter bottle with a filter material filling function, a water channel conversion mechanism and a primary pollutant treatment mechanism; the primary pollutant treatment mechanism includes both a conventional filtering mechanism for filtering visible impurities in water and a pollutant treatment mechanism capable of absorbing, filtering and catalytically decomposing invisible residual chlorine, compounds, heavy metals and spore cysts in water;

[0008] The filter bottle is fully enclosed in the circumference, with a water inlet channel at the bottom and a water outlet at the top, and the water channel conversion mechanism is detachably arranged at the water outlet at the top of the filter bottle;

[0009] The primary pollutant treatment mechanism is detachably arranged outside the filter bottle, and the water channel conversion mechanism is provided with a raw water channel and a clean water channel. The raw water channel is connected with the water inlet, the raw water cavity formed between the outer wall of the primary pollutant treatment mechanism and the tank body, and the water inlet channel, and the clean water channel is connected with the water flow channel inside the filter bottle and the water outlet.

[0010] In the present invention, firstly, the raw water channel and the purified water channel are fully independent and do not interfere with each other.

When passing through the primary pollutant treatment mechanism, it undergoes a primary purification treatment, and then enters the scale-inhibiting filter material through the water inlet channel. With this structural design, the water flow can penetrate the scale-inhibiting filter material and fully prevent scale. The water purification reliability is high.
