Description

Technical Field

[0001] The utility model relates to the technical field of water purifier bottle caps, in particular to a triple-seal structure of a water purifier. Background Art

[0002] The filter bottle of a water purifier is an important component in the water purifier, mainly used for installing a filter element and filtering water quality to prevent secondary pollution of the water source. It is made of materials such as PP and ABS plastics. Its structure includes a filter bottle cap, a bottle body, and an internal filter element structure. In existing water purifiers, the filter element is generally placed in a normal position, that is, the bottle body is below and the bottle cap is above. In this way, due to the buoyancy factor of the water to be purified, the sealing performance of the sealing rings between the bottle cap and the outside and between the bottle body and the filter element is relatively reliable. However, once the bottle cap and the bottle body are placed upside down or horizontally, due to the lack of corresponding limiting structures, the sealing rings will fall off, resulting in water leakage. Summary of the Utility Model

[0003] In order to solve the technical problem that the sealing ring of the water purifier filter bottle cap in the existing design is prone to falling off when placed upside down or horizontally, resulting in leakage between the filter element and the filter bottle and affecting the sealing effect, the utility model provides a triple-seal structure of a water purifier.

[0004] The technical solution of the utility model is realized through the following scheme: A triple-seal structure of a water purifier includes a first bottle cap, a second bottle cap, and a third bottle cap that are sequentially arranged at intervals. A water delivery pipe group is integrally installed on the first bottle cap, the second bottle cap, and the third bottle cap; water inlet ports and water outlet ports are respectively arranged at both ends of the water delivery pipe group. Filter water hole groups and filter element hole columns communicating with the water delivery pipe group are respectively opened on the first bottle cap, the second bottle cap, and the third bottle cap. A filter element sealing ring is arranged between the filter water hole group and the filter element hole column.

[0005] By using the above technical solution, a sealing ring is arranged in the filter element sealing groove structure formed between the filter element sealing ring and the filter element hole column, so as to prevent leakage of water quality between the inside and outside of the filter element and the bottle body, making the water quality can only pass through the filter element structure for filtration and purification as the only channel. At the same time, the setting of the filter element sealing ring restricts the expansion displacement of the sealing ring, preventing the problem of the sealing ring falling off when the overall structure is inverted or placed horizontally.

[0006] Preferably, a filter element sealing groove is formed between the filter element sealing ring and the filter element hole column.

[0007] Preferably, a filter bottle sealing ring is arranged in the lid body outside the filter water hole group.

[0008] By using the above technical solution, in the structural design of the filter bottle sealing ring, a groove structure is formed between the filter bottle sealing ring and the filter bottle cap to place the sealing ring, and the filter bottle and the filter bottle cap are sealed to prevent leakage, thus preventing the leakage of filtered water.

[0009] Preferably, slot plates are respectively arranged on the upper parts of the first bottle cap, the second bottle cap and the third bottle cap.

[0010] Preferably, groove holes are formed in the slot plates, and the two groups of slot plates are symmetrically arranged on the upper part of the bottle cap.

[0011] By using the above technical solution, the filter bottle cap and the purification device are fixedly connected by the insertion of the slot plate and the groove hole. The insertion structure is convenient to operate and is convenient for disassembling and replacing the filter element structure.

[0012] Preferably, the water delivery pipe group includes a first pipe group and a second pipe group. The first pipe group and the second pipe group are arranged along the same axis direction, and the first pipe group and the second pipe group are not connected.

[0013] Preferably, reinforcing rib plates are respectively arranged between the first bottle cap and the second bottle cap and between the second bottle cap and the third bottle cap.

[0014] By using the above technical solution, the setting of the reinforcing rib plates ensures the integral rigid fixation between the three bottle caps, reduces the bending property between the three filter bottle caps, prevents the inclination of each filter bottle after installation, or the elastic deformation caused by the bending of the filter bottle caps, so as to avoid the leakage problem caused by the loose connection between the filter bottle and the bottle cap.

[0015] In summary, the utility model has the following beneficial effects:

[0016] 1. In the filter element sealing groove structure formed between the filter element sealing ring and the filter element hole column of the utility model, a sealing ring is arranged, so as to prevent leakage of the water quality between the inside and outside of the filter element and the bottle body, making the water quality can only be filtered and purified through the filter element structure as the only channel. At the same time, the setting of the filter element sealing ring restricts the expansion displacement of the sealing ring and prevents the problem of the sealing ring falling off when the whole structure is inverted or placed horizontally.

[0017] 2. Further, in the structural design of the filter bottle sealing ring, a groove structure is formed between the filter bottle sealing ring and the filter bottle cap to place the sealing ring, and the filter bottle and the filter bottle cap are sealed to prevent leakage, thus preventing the leakage of filtered water.

[0018] 3. The way of inserting the slot plate into the groove holes is used to fixedly connect the filter bottle cap and the purification device. Its insertion structure is convenient for operation, easy to disassemble and replace the filter element structure. At the same time, the setting of the reinforcing rib plates ensures the integral rigid fixation among the three groups of bottle caps, reduces the bending property among the three groups of filter bottle caps, prevents the inclination of each group of filter bottles after installation, or the elastic deformation caused by the bending of the filter bottle caps, so as to avoid the leakage problem caused by the loose connection between the filter bottle and the bottle cap.

[0026] This embodiment provides a triple-seal structure of a water purifier, as Figures 1-4As shown in the figure, it includes a first bottle cap 1, a second bottle cap 2, and a third bottle cap 3 that are sequentially arranged at intervals. The first bottle cap 1, the second bottle cap 2, and the third bottle cap 3 are of an integrally thermoplastic structure. Reinforcing rib plates 14 are respectively arranged between the first bottle cap 1 and the second bottle cap 2 and between the second bottle cap 2 and the third bottle cap 3. The reinforcing rib plates 14 and the outer edge of the cap body are of an integrally thermoplastic structure, thus ensuring the stability of the distance between the bottle caps. A water delivery pipe group 4 is integrally installed on the first bottle cap 1, the second bottle cap 2, and the third bottle cap 3; water inlet ports 5 and water outlet ports 6 are respectively arranged at both ends of the water delivery pipe group 4. Filter water hole groups 7 and filter element hole columns 8 communicated with the water delivery pipe group 4 are respectively arranged on the first bottle cap 1, the second bottle cap 2, and the third bottle cap 3. The water delivery pipe group 4, the filter water hole groups 7, and the filter element hole columns 8 are used as the flow-through holes for sequential water purification. The water inlet port 5 is the initial purification water inlet, and the water outlet port 6 is the water outlet for completed purification, finally completing the purification and filtration of the water quality; a filter element sealing ring 9 is arranged between the filter water hole group 7 and the filter element hole column 8. A filter element sealing groove 10 is formed between the filter element sealing ring 9 and the filter element hole column 8. Through the added filter element sealing ring 9 structure, the expansion and floating of the sealing ring are restricted, so that when the sealing ring is installed and inverted or installed horizontally, the sealing ring between the filter element and the filter bottle will not become loose or fall off.

[0027] Furthermore, a filter bottle sealing ring 11 is arranged inside the cap body outside the filter water hole group 7. The groove structure formed between the filter bottle sealing ring 11 and the inner cavity of the cap body is used to place the sealing ring, thereby preventing the seal leakage between the filter bottle and the cap body.

[0028] Furthermore, slot plates 12 are respectively arranged on the upper parts of the first bottle cap 1, the second bottle cap 2, and the third bottle cap 3. Two groups of symmetric slot plates 12 are arranged on each group of bottle caps and are integrally cast on the bottle caps. Groove holes 13 are opened on the slot plates 12. The slot plates 12 and the groove holes 13 are inserted to fixedly install the bottle caps and the filter bottle on the water purifier device, and at the same time, it is convenient for disassembly and replacement of the filter element.

[0029] At the same time, the water delivery pipe group 4 includes a first pipe group 41 and a second pipe group 42. The first pipe group 41 and the second pipe group 42 are arranged along the same axis direction and are not connected. The first pipe group 41 is connected to the filter water hole group 7 and the filter element hole column 8 of the first bottle cap 1 and the filter water hole group of the second bottle cap 2; the second pipe group 42 is connected to the filter element hole column 8 of the second bottle cap 2 and the filter water hole group 7 and the filter element hole column 8 of the third bottle cap 3. Among them, the structures of the filter water hole groups 7 opened on the first bottle cap 1 and the third bottle cap 3 are the same, and both include communication holes and blocking holes. The communication holes introduce the water in the water pipe into the filter bottle, and the blocking holes block the water flow in the water delivery pipe group 4 to change its flow direction and enter the filter bottle for filtration treatment; the filter water hole group 7 opened on the second bottle cap 2 only has communication holes and no blocking holes. Because the second pipe group 42 is not connected to the first pipe group 41, there is no need to set blocking holes.
