The invention discloses a healthcare kneecap which comprises a kneecap body and a heat circulating device. The heat circulating device is arranged on a middle interlayer part of the kneecap body or the side, close to the skin, of the kneecap body, the heat circulating device comprises a heat radiation part and a heat absorption part, and the heat radiation part and the heat absorption part are connected end to end to form a heat circulating hoop; circulating media are arranged in the heat radiation part and the heat absorption part. According to the healthcare kneecap, the muscle heat of the thighs and the crura can be efficiently transmitted to the knees, heat preservation of the knees is guaranteed, external energy input is not needed, and the cost is low. The media flowing back in all heat absorption circulating loops can be mixed together through a flat integrated channel, and temperature balance is guaranteed. The heat transferring effect is good; the medium circulating efficiencyis improved. The flowing direction of the media is guaranteed, one-way flowing of the circulating media is smoother, and the heat absorption effect is good.
