Description

Technical Field

[0001] The utility model relates to the field of drinking water purification, and specifically to a filter element component for direct drinking water. Background Art

[0002] In daily life, water is an indispensable resource for human life activities. Generally, residents use water directly from the water plant through water pipes. However, this water is usually not drinkable directly. It needs to be boiled or purified by a water purifier to remove impurities and chemicals in the water. An activated carbon filter element is used inside the existing water purifier. When in use, the water purifier can be directly connected to the tap water pipe. After the tap water enters the water purifier, it first enters the water inlet of the filter element, and clean water is obtained after adsorption and filtration by activated carbon, and then discharged through the water outlet. However, the existing filter element inlet and outlet are small, and are easily blocked after long-term use or when there are many impurities in the water, which greatly reduces the purification efficiency. In this case, the filter element can only be replaced, which increases the cost of water purification. To this end, we propose a filter element assembly for direct drinking water. Utility Model Content

[0003] The utility model aims to provide a filter element assembly for direct drinking water, so as to solve the problem in the above-mentioned background technology that some filter elements have small water inlet and outlet, which are easily blocked after long-term use or when there are many impurities in the water.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a filter element assembly for direct drinking water, comprising a filter element housing, one end of the filter element housing is provided with two water inlet pipes, and the water inlet pipes are respectively connected to the filter element housing by a fixing nut; the other end of the water inlet pipe is connected to a diversion mechanism capable of diverting the water inlet pipe.

[0005] Among them, the diversion mechanism includes a tee pipe connected to two water inlet pipes, and the tee pipe is connected to the water inlet pipe by a second fixing nut; the other end of the tee pipe has a water inlet, and a piston rod is provided inside the tee pipe, and a rubber plug is provided on the piston rod, and the piston rod is also provided with a limit device.

[0006] Wherein, the water inlet is parallel to the water inlet pipe, and the water inlet and the water inlet are on different sides.

[0007] Wherein, the rubber plug is spherical and is located at the center of the piston rod.

[0008] Among them, the limiting device includes limiting rods arranged on both sides of the piston rod, piston rod guide sleeves are arranged on both sides of the three-way pipe, and the piston rod is located inside the piston rod guide sleeve, and limiting grooves are arranged at both ends of the piston rod guide sleeve.

[0009] Among them, the limit groove is "L" shaped and is equipped with a rubber pad. When one end of the piston rod is pushed into the three-way pipe, the limit rod on the same end of the piston rod can enter the limit groove. When the piston rod is pushed to the maximum distance, the piston rod can be rotated to make the limit rod fit with the rubber pad.

[0010] Wherein, the rubber pad is located in the inner part of the limiting groove and perpendicular to the opening.

[0011] The utility model has at least the following beneficial effects:

[0012] First, the water inlet pipe is changed to be detachable, and two are added, and a tee is installed at the same time. When one water inlet pipe is blocked, the piston rod in the tee can be pushed to drive the rubber plug, so as to achieve the effect of switching the water inlet pipe, which can quickly cut off the water flow blocking the water inlet pipe and make the water flow to the normal water inlet pipe. At the same time, the unused water inlet pipe can be disassembled and replaced without affecting the normal operation of the filter element. The rubber plug in the tee is designed to be spherical, and its diameter is slightly larger than the tee pipe. It is flexible and convenient to use and can also ensure good sealing. At the same time, a piston rod guide sleeve is added at the junction of the piston rod and the tee to prevent the piston rod from being dislocated or broken. There is a limit groove on the piston rod guide sleeve, which is used in conjunction with the limit stick on the piston rod. When the piston rod is pushed into place, the piston rod can be rotated so that the limit stick is stuck in the limit groove. There is a rubber pad in the limit groove, which can effectively prevent the piston rod from shifting due to gravity or other factors, so that the rubber plug cannot perfectly block the tee pipe mouth.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 4 , Example

[0020] The utility model provides a technical solution: a filter element assembly for direct drinking water, comprising a filter element housing 1, one end of the filter element housing 1 is provided with two water inlet pipes 2, the water inlet pipes 2 are respectively connected to the filter element housing 1 by fixing nuts 3; the other end of the water inlet pipe 2 is connected to a diversion mechanism 4 capable of diverting the water inlet pipe 2, and the diversion mechanism 4 is connected by fixing nuts 41;

[0021] When in use, by changing the water inlet pipe 2 to be detachable and increasing the number to two, and installing a three-way pipe 40 at the same time, when one water inlet pipe 2 is blocked, the rubber plug 44 can be driven by pushing the piston rod 43 in the three-way pipe 40, so as to achieve the effect of switching the water inlet pipe 2, and the water flow blocking the water inlet pipe 2 can be quickly cut off and the water can flow to the normal water inlet pipe 2. At the same time, the water inlet pipe 2 that is not in use can be disassembled and replaced without affecting the normal operation of the filter element. The rubber plug 44 in the three-way pipe 40 is designed to be spherical, and its diameter is slightly larger than the three-way pipe 40. It is flexible and convenient to use while ensuring good sealing. At the same time, a piston rod guide sleeve 51 is added at the junction of the piston rod 43 and the three-way pipe 40 to prevent the piston rod 43 from being dislocated or broken. There is a limiting groove 52 on the piston rod guide sleeve 51, which is used in conjunction with the limiting rod 50 on the piston rod 43. When the piston rod 43 is pushed into place, the piston rod 43 can be rotated so that the limiting rod 50 is stuck in the limiting groove 52. There is a rubber pad 53 in the limiting groove 52, which can effectively prevent the piston rod 43 from shifting due to gravity or other factors, thereby making it impossible for the rubber plug 44 to perfectly block the pipe opening of the three-way pipe 40.

[0022] The diversion mechanism 4 includes a tee pipe 40 connected to the two water inlet pipes 2, and the tee pipe 40 is connected to the water inlet pipe 2 by a fixing nut 41; the other end of the tee pipe 40 has a water inlet 42, the water inlet 42 is parallel to the water inlet pipe 2, and the water inlet 42 and the water inlet pipe 2 are on different sides, the interior of the tee pipe 40 is provided with a piston rod 43, the piston rod 43 is provided with a rubber plug 44, the rubber plug 44 is spherical, its diameter is slightly larger than the inner diameter of the tee pipe 40, and the rubber plug 44 is located at the center of the piston rod 43;

[0023] When the diversion mechanism 4 is in use, water flows from the water inlet 42 into the three-way pipe 40. The direction of the water flow can be controlled by pushing the piston rod 43 to achieve the purpose of selecting the water inlet pipe 2. The rubber plug 44 on the piston rod 43 is spherical. When the piston is pushed into place, the rubber plug 44 can just block one of the pipe openings. If the water inlet pipe 2 needs to be replaced, it is only necessary to push the piston rod 43 in the opposite direction. The piston rod 43 is also provided with a limit device 5; Example

[0024] In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the limiting device 5 includes limiting rods 50 on both sides of the piston rod 43, piston rod guide sleeves 51 are provided on both sides of the tee pipe 40, and the piston rod 43 is located inside the piston rod guide sleeve 51. Limiting grooves 52 are provided at both ends of the piston rod guide sleeve 51. The limiting grooves 52 are "L"-shaped and are equipped with rubber pads 53. The rubber pads 53 are located in the inner part of the limiting grooves 52 that is perpendicular to the opening. When one end of the piston rod 43 is pushed into the tee pipe 40, the limiting rod 50 on the same end of the piston rod 43 can enter the limiting groove 52. When the piston rod 43 is pushed to the maximum distance, the piston rod 43 can be rotated to make the limiting rod 50 fit the rubber pad 53.

[0025] When the limiting device 5 is in use, the piston rod guide sleeves 51 arranged on both sides of the three-way pipe 40 can limit the movement of the piston rod 43 to prevent the piston rod 43 from being misplaced during the pushing process. When in use, the limiting rod 50 on the piston rod 43 can enter the limiting groove 52. After being pushed into the deepest part of the limiting groove 52, the piston rod 43 can be rotated. The limiting rod 50 rotates with the piston rod 43, and the limiting rod 50 is stuck in the inner side of the limiting groove 52. The rubber pad 53 installed on the inner side of the limiting groove 52 makes it difficult for the limiting rod 50 to slip off.
