Description

TECHNICAL FIELD

[0001] The utility model relates to a water tank and a water purifier. BACKGROUND

[0002] At present, the water purifying equipment filters the impurities in tap water through the filter element, so as to obtain purified water. Due to the influence of the booster pump and the filter membrane, the general purified water flow rate is not very large. In order to provide better water experience for users, there is a kind of volumetric large flow water purifying equipment, which sets a water tank in the equipment, stores the purified water produced in the water tank, and realizes large flow water output through a large flow water pump. This volumetric large flow water purifying equipment can provide large flow water output, but if the user does not use water for a long time, there is also a problem that the water tank is easy to breed bacteria. In order to solve the problem of bacterial breeding, a static sterilization lamp is generally arranged in the water tank. The bacteria in the water tank are killed or inhibited by the sterilization lamp. However, the existing water tank is made of food-grade plastic material. The plastic will accelerate aging under the long-time irradiation of the sterilization lamp, which will cause the inner wall of the water tank to turn yellow and even fall off, thereby shortening the service life of the water tank and being not conducive to health. SUMMARY

[0003] The technical problem to be solved by the utility model is to overcome the defect that the water tank in the prior art is easy to age under the irradiation of the sterilization lamp, and to provide a water tank and a water purifier.

[0004] The utility model solves the above technical problems through the following technical scheme:

[0006] In the scheme, the water tank is provided with a light blocking piece in the water storage cavity. When the sterilization lamp is turned on to sterilize the water in the channel, the light projected by the sterilization lamp is irradiated on the light blocking piece. The light blocking piece blocks the light projected by the sterilization lamp, avoiding the light of the sterilization lamp directly irradiating on the inner wall of the tank body, so as to protect the tank body made of plastic material, prevent the tank body from aging and falling off, prolong the service life of the tank body, and improve the water safety.

[0014] In this scheme, the light blocking member divides the water storage cavity and sets the germicidal lamp in the first cavity, so that the light projected by the germicidal lamp is limited in the area surrounded by the light blocking member, reducing the damage of the light of the germicidal lamp to the inner wall of the tank body and prolonging the service life of the tank body. The water passing hole is provided on the light blocking member, and when the rotating member is working, the water in the second cavity can flow to the first cavity through the water passing hole, and the water in the first cavity can flow to the second cavity through the backflow hole, forming a circulation path, so that the water in the water storage cavity can be sterilized by the germicidal lamp, thereby improving the sterilization effect.

[0015] Preferably, the light blocking member and the side wall of the tank body surround the backflow hole.

[0016] In the scheme, the above structure is adopted, so that the water flow can cover a larger range when the rotating member is working, and the sterilization effect is improved.

[0017] Preferably, the light blocking member is provided with the backflow holes on both sides.

[0018] In the scheme, the above structure is adopted, so that the water flow can cover a larger range when the rotating member is working, and the sterilization effect is improved.

[0019] Preferably, a gap is reserved between the periphery of the light blocking member and the side wall of the box.

[0020] In the scheme, when the rotating member is working, the rotating member drives the water to move around through the water passing holes on the light blocking member, and then moves along the gap between the box and the light blocking member, and finally forms a circulation path, thereby improving the sterilization effect.
