Description

Technical Field

[0001] This utility model relates to a water cup, and more particularly to a water cup filter structure. Background Technology

[0002] As society develops, people are raising their standards for health. Water is the source of life for humankind, therefore ensuring the quality of drinking water is an important part of maintaining human health.

[0003] In order to effectively remove various harmful substances from water, many water cups with filter cartridges have appeared on the market (such as CN201520170607-A filter cartridge for water cups-Utility Model), which protect people's drinking water health.

[0004] The filter cartridge with the above structure has multiple first water inlet holes around the filter cartridge body. However, when the water level in the cup drops below some of the first water inlet holes, if the user drinks water at this time, the first water inlet hole above the water level will be sucked in with air. The air will mix with the water flow and enter the user's mouth from the column and the straw connected to the column, causing a decrease in the amount of water absorbed. Moreover, as the water level drops lower and lower, the user will drink less and less water and more and more air, and may even be unable to absorb water.

[0005] Therefore, the applicant designed a water cup filter element structure to solve the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a water cup filter element structure.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A water cup filter structure includes a straw, a filter body, and a plurality of first water inlets disposed around the filter body. The characteristic is that it further includes the outer shell, the bottom end of the outer shell is provided with a second water inlet, the filter body is disposed in the outer shell, and the straw is connected to the water outlet pipe of the filter body.

[0009] The outer casing is provided with mounting holes and a rubber sleeve disposed in the mounting holes. The suction tube and the water outlet tube are both inserted into the rubber sleeve and connected through the rubber sleeve.

[0010] The end plate of the outer casing is provided with an end tube, and the mounting hole is the inner hole of the end tube and communicates with the outer casing.

[0011] The rubber sleeve includes an upper positioning edge and a lower positioning edge disposed on the outside of the rubber sleeve. The upper positioning edge is located outside the outer shell and abuts against the end face of the end tube; the lower positioning edge is located inside the outer shell and abuts against the end plate.

[0012] The outer shell includes an upper shell and a lower shell, which are connected by a rotating snap-fit ​​structure. The mounting hole is located on the upper shell, while the second water inlet is located on the lower shell.

[0013] The second water inlet is a plurality of mesh holes provided on the bottom surface of the lower shell, and the bottom end of the filter element body abuts against the lower shell.

[0014] The bottom end of the upper shell is provided with an annular connecting plate, and the rotating buckle structure is disposed between the connecting plate and the lower shell.

[0015] The beneficial effects of this utility model are as follows: This utility model has a shell on the filter body, and a second water inlet is provided at the bottom of the shell. Therefore, when drinking water, water can only enter through the second water inlet first. Since the second water inlet is located at the bottom of the shell, as long as the second water inlet is below the water surface, no air will be sucked into the second water inlet and the first water inlet, causing the user to drink less and less water. This solves the problem of drinking a lot of bubbly water and having residual water at the bottom of the cup when the water level is low in other types of filter cups. Attached Figure Description

The embodiments of this disclosure may be implemented independently of each other, or may be implemented together in an interdependent relationship.

[0028] Reference Figures 1 to 4 This utility model discloses a water cup filter element structure, including a straw 1, a filter element body 2, and a plurality of first water inlet holes 3 disposed around the filter element body 2. In the above structure, the filter element body 2 is purchased externally and includes a cylindrical plastic shell. One end of the filter element body 2 has a water outlet pipe 4, and the other end has a water inlet pipe. A plurality of first water inlet holes 3 are disposed on the circumferential side of the plastic shell. The plastic shell contains filter material, which can be activated carbon, PP cotton, etc. The structure of the filter element body 2 is a conventional structure, so it will not be described in detail.

[0029] As shown in the figure, the outer shell 5 is also included. The outer shell 5 of this application is made of food-grade PP material and is shaped like a cylinder. The filter body 2 is completely disposed in the outer shell 5. The bottom end of the outer shell 5 is provided with a second water inlet 6, and the straw 1 is connected to the water outlet pipe 4 of the filter body 2. Therefore, with the above structure, when the user drinks water, as long as the second water inlet 6 is below the water surface, no air will be sucked into the second water inlet 6 and the first water inlet 3, causing the user to drink less and less water.

[0030] As shown in the figure, the outer shell 5 is provided with a mounting hole and a rubber sleeve 7 disposed in the mounting hole. The straw 1 and the water outlet pipe 4 are both inserted into the rubber sleeve 7 and connected through the rubber sleeve 7. The rubber sleeve 7 is made of food-grade silicone material, which is relatively soft. Therefore, the rubber sleeve 7 can be tightly connected with the mounting hole. Moreover, the straw 1 and the water outlet pipe 4 will also form a tight fit with the rubber sleeve 7 through the rubber sleeve 7. The above structure is not only convenient to connect and easy to disassemble and replace the filter body 2, but also has a sealing effect, ensuring that water or air will not enter from the gap between the outer shell 5 and the rubber sleeve 7, or between the straw 1, the water outlet pipe 4 and the rubber sleeve 7 when the user drinks water. As a further structure, the rubber sleeve 7 is provided with a filter tube hole. The mounting hole and the filter tube hole are connected, and the diameter of the mounting hole is smaller than the diameter of the filter tube hole. In this way, a step is formed at the junction of the mounting hole and the filter tube hole, which facilitates the positioning of the water outlet pipe 4 during installation.

[0031] As shown in the figure, the end plate 8 of the outer shell 5 is provided with an end tube 9. The mounting hole is the inner hole of the end tube 9 and is connected to the outer shell 5. This increases the length of the mounting hole, thereby increasing the contact area between the rubber sleeve 7 and the mounting hole, resulting in a tighter connection and facilitating sealing.

[0032] As a further structural feature, the rubber sleeve 7 includes an upper positioning edge 10 and a lower positioning edge 11 disposed on the outside of the rubber sleeve 7. The upper positioning edge 10 is located outside the outer shell 5 and abuts against the end face of the end tube 9; the lower positioning edge 11 is located inside the outer shell 5 and abuts against the end plate 8. This not only ensures that the rubber sleeve 7 is installed more securely and will not move up and down in the mounting hole, but also increases the contact area, which is beneficial for sealing.

[0033] As shown in the figure, the outer shell 5 includes an upper shell 12 and a lower shell 13, which are connected by threads. The mounting hole is located on the upper shell 12, and the second water inlet 6 is located on the lower shell 13. This structure facilitates manufacturing and installation. When removing the filter element body 2, simply rotate the lower shell 13 to detach it from the upper shell 12, then insert the filter element body 2 into the upper shell 12 and insert the water outlet pipe 4 into the silicone sleeve, thereby connecting the filter element body 2. Then, assemble the lower shell 13 and the upper shell 12 together to complete the filter element installation. As a further structure, the upper shell 12... The bottom end of 2 is provided with an annular connecting plate 14, which has an external thread and the lower shell 13 has an internal thread. The outer diameter of the annular connecting plate 14 and the inner diameter of the lower shell 13 are the same, so that the outer surface of the upper shell 12 and the lower shell 13 is relatively flat and beautiful after connection. Of course, the upper shell and the lower shell of this application can also be connected by a rotating buckle structure, and the mounting hole is set in the upper shell, while the second water inlet hole is set in the lower shell. Preferably, the rotating buckle structure is set between the connecting plate and the lower shell. The rotating buckle structure is a conventional buckle structure, so it will not be described in detail.

[0034] As a further structural feature, the second water inlet 6 is a series of mesh holes on the bottom surface of the lower shell 13, so that the bottom surface of the lower shell 13 is not completely open, and thus the bottom end of the filter element body 2 can abut against the lower shell 13, thereby fixing the filter element body 2.

[0035] The above provides a detailed description of a water cup filter structure provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
