Description

Technical Field

[0001] The utility model relates to a watertight pure water tank for a drinking water purifier. Background Art

[0002] At present, there is no sealing measure between the upper cover and the water tank body of ordinary pure water tanks. When draining or filling water, breathing is done through the gap between the upper cover and the water tank body, but water will leak out. Alternatively, an air vent is directly opened on the upper cover without any measures to prevent water leakage. Summary of the invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a watertight pure water tank for a water purifier. The upper cover is sealed with the water tank body, the water tank is communicated with the outside through a waterproof and breathable non-woven fabric, the water tank can inhale and exhale but will not leak, is easy to use, and has a compact structure.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is implemented as follows: it is a watertight pure water tank for a water purifier, which is characterized by comprising:

[0005] A water outlet pipeline, a pure water tank and a water inlet pipeline; the water inlet pipeline, the pure water tank and the water outlet pipeline are connected in sequence, and a through hole is provided on the outer wall of the pure water tank; and

[0006] A water pipe structure and a waterproof and breathable non-woven fabric; the water pipe structure is inserted into the through hole, and the waterproof and breathable non-woven fabric is installed at the water inlet or outlet or the water inlet and outlet of the water pipe assembly.

[0007] In the technical solution, the through hole is located at the upper cover of the pure water tank.

[0008] In the technical solution, a sealing ring is also included. An inwardly recessed step is provided on the water pipe structure, a sealing groove is provided at the through hole, the sealing ring is located at the sealing groove, and the step abuts against the sealing ring to form a sealing fit.

[0009] Compared with the prior art, the utility model has the following advantages: the upper cover is sealed with the water tank body, the water tank is connected with the outside through the waterproof and breathable non-woven fabric, the water tank can inhale and exhale without leaking, it is easy to use and has a compact structure.

[0015] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various implementation methods of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0016] like Figures 1 to 5 As shown, it is a watertight pure water tank for a water purifier, comprising:

[0017] A water outlet pipeline 1, a pure water tank 2 and a water inlet pipeline 3; the water inlet pipeline 3, the pure water tank 2 and the water outlet pipeline 1 are connected in sequence, and a through hole 21 is provided on the outer wall of the pure water tank 2;

[0018] Water pipe structure 5 and waterproof breathable non-woven fabric 4; the water pipe structure 5 is inserted into the through hole 21, and the waterproof breathable non-woven fabric 4 is installed at the water inlet or outlet or the water inlet and outlet of the water pipe assembly.

[0019] During operation, the inner cavity of the pure water tank 2 is connected to the external gas through the waterproof and breathable non-woven fabric 4, so that inhalation and exhalation can be performed, so that the air pressure in the inner cavity is consistent with the outside, and water flows in and out smoothly. Due to the effect of the waterproof and breathable non-woven fabric 4, water cannot flow out through the waterproof and breathable non-woven fabric.

[0020] In this embodiment, the through hole 21 is located at the upper cover of the pure water tank 2 .

[0021] In this embodiment, a sealing ring 7 is also included. An inwardly recessed step 51 is provided on the water pipe structure 5. A sealing groove 211 is provided at the through hole 21. The sealing ring 7 is located at the sealing groove 211, and the step 51 abuts against the sealing ring 7 to form a sealing fit. When in use, the sealing effect is better to prevent water from leaking out.

[0022] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For ordinary technicians in this field, various changes, modifications, substitutions and deformations of these embodiments without departing from the principle and purpose of the present invention still fall within the scope of protection of the present invention.
