The shapes of the piercing point 64 and the piercing base 63 are different, but they both ensure the piercing point 64 pierces the sealing cover 11 of the beverage substance cartridge 1, and keep good tightness.

The substance in the cartridge body is any one of or at least two of tea leaf, dried vegetable, dried fruit and Chinese medicinal herb. The beverage producing system of the invention could produce tea drinks, fruit and vegetable drinks, Chinese medicinal herb health care drinks, etc., and some tea could be brewed for more than one time.

To sum up, the invention has the following advantages and positive effects:

The invention provides the beverage substance cartridge, the tea filtering apparatus, the beverage producing equipment, the beverage producing system and the beverage producing method to efficiently filter tea leaf and get rid of the trouble of clearing used tea leaves manually. Wherein the beverage substance cartridge is used in conjunction with the tea filtering apparatus, the piercing point of the triangular pyramid structure could pierce the sealing cover of the beverage substance cartridge and then form matrix-shaped filtering holes in the sealing cover, brewed tea water could flow out, and used tea leaf is left in the extracting cartridge, so the filtering process is simple and convenient without clearing away tea leaves manually.

It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. It is understood, therefore, that this invention is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present invention as defined by the appended claims.

Claims
