Step self-absorption type double-layer flowerpot

Abstract

The invention provides a step self-absorption type double-layer flowerpot, comprising an outer flowerpot and an inner flowerpot. A water filling cavity is arranged in the outer flowerpot. The inner flowerpot is bridged on the outer flowerpot. The bottom surface of the inner flowerpot is downwardly concave to the water filling cavity so as to form a water absorption part. The outer flowerpot is made of a conventional ceramic raw material. The water absorption of the conventional ceramic raw material is less than 5%. The inner flowerpot is manufactured by comprising the following steps of: mixing and stirring 65-68% of a mixed material, 30-33% of clear water and 1-2% of water glass for 2-3 h; after manufacturing a clay material slip casting formed inner flowerpot adobe, removing 0.3-0.5 mm of a clay layer on the surface of the adobe by grinding; sintering the inner flowerpot adobe, wherein the highest sintering temperature is 1050-1080 DEG C, the total sintering time is 7.5-8.5 h, and the sintering time at the temperature of 400-600 DEG C is 2.5-3.5 h; and then, manufacturing the inner flowerpot. The inner flowerpot disclosed by the invention has the advantages of good water absorption and water storage performances, strong plastically, high intensity, environment protection and low cost. A double-layer flowerpot product can be applicable to different moisture demanded quantities of different plants. A selective water absorption space is provided to the plants.

Description

technical field [0001] The invention relates to a flower pot, in particular to a stepped self-suction double-layer flower pot. Background technique [0002] The inventor applied for a utility model patent with a patent number of 200920237501.6 in 2009. This patented product can make the soil use water-absorbing cores to absorb water to supply plant growth needs, so that people who are often on business trips or are usually busy can water at one time. Plants need it for a long time, but because the absorbed water is basically concentrated near the water-absorbing core, the roots of plants can only get water when they grow to the vicinity of the water-absorbing core, and the water content here is basically the same, so plants cannot Moisture is required for selection. Moreover, porcelain flower pots cannot absorb water, while flower pots made of traditional ceramic materials generally have a water absorption rate of less than 18%, and have good air permeability, but it is dif...

[0002] The inventor applied for a utility model patent with a patent number of 200920237501.6 in 2009. This patented product can make the soil use water-absorbing cores to absorb water to supply plant growth needs, so that people who are often on business trips or are usually busy can water at one time. Plants need it for a long time, but because the absorbed water is basically concentrated near the water-absorbing core, the roots of plants can only get water when they grow to the vicinity of the water-absorbing core, and the water content here is basically the same, so plants cannot Moisture is required for selection

Moreover, porcelain flower pots cannot absorb water, while flower pots made of traditional ceramic materials generally have a water absorption rate of less than 18%, and have good air permeability, but it is difficult for water to penetrate from the pot wall to the other side. Only when the water absorption rate exceeds 30%, can the effect of water absorption be achieved, and when the water absorption rate of ceramic products exceeds 18%, its strength is not enough, and the product is easily damaged during movement or use, which affects the use of the product
