Description

A prefilter bottle for a water purification system

technical field

The utility model relates to the technical field of filter bottle technology, in particular to a pre-filter bottle of a water purification system.

Background technique

With the advancement of science and technology and the improvement of people's living standards, people have begun to have higher requirements for the health of water in daily life. Therefore, people often install water purification systems at the tap water pipes, and the pre-filter bottle is used as the main part of the water purification system. The preliminary filter device is used to filter large impurities such as sediment, rust, and floating matter, so as to reduce the loss of the post-purification system and reduce the number of times of replacing the post-filter element for water purification. The pre-filter bottle serves as a larger filter particle. The internal filter element needs to be replaced frequently. In the existing pre-filter bottle, the position of the cover body is generally fixed by angle iron, and the bottle body is fixed under the cover body. When disassembling, it is usually pulled with a wrench. The bottle body and the bottle cap are separated after the bottle body is rotated, so when the bottle body is pulled, the position of the bolt fixing the cap body is far away from the force position of the bottle body, so a lever effect will be generated during disassembly. It is easy to deform and damage the bolts that fix the cover body, and it is very troublesome to disassemble. In addition, when the filter element is replaced, it is impossible to continue the water supply operation, which leads to inconvenience of water use. Therefore, we propose a pre-filter bottle for the water purification system.

The internal filter element 3 is replaced to ensure that the water can be used normally during the process of disassembling the bottle body 1, so that the subsequent filtration system can not be shut down. Because the time interval for replacing the filter element 3 is very short, there is no pre-filter for a short time. will have a greater impact.

When the bottle body 1 is disassembled, in order to quickly release the pressure inside the bottle body 1 and facilitate the easy disassembly of the bottle body 1, specifically, a pressure relief valve 14 is fixedly installed on the cover body 2, so The pressure relief valve 14 includes a pressure relief chamber 1401, and the position of the pressure relief chamber 1401 can be communicated with a water filter hole 13 behind the valve block 11 (as shown in Figures 5 and 6). A closing plate 1403 is slidably connected inside through a spring 1402. A first sealing ring 1405 is provided between the upper side of the closing plate 1403 and the side wall of the pressure relief chamber 1401. The first sealing ring 1405 is made of rubber, and the first sealing ring is made of rubber. 1405 can ensure that the upper side of the closing plate 1403 and the side wall of the pressure relief chamber 1401 are in a sealed state to avoid leakage of the pressure relief valve 14. A pressing block 1404 is arranged in the middle of the upper side of the plate 1403. The pressing block 1404 penetrates the side wall of the pressure relief chamber 1401 and extends to the outside. When the bottle body 1 needs to be disassembled, the valve block 11 is rotated to make a water filter hole 13 Connect with the pressure relief chamber 1401, and then press 1404 to make the closing plate 1403 slide down against the elastic force of the spring 1402, so that the upper side of the closing plate 1403 and the side wall of the pressure relief chamber 1401 are separated, and then the gas inside the bottle 1 will be released from the notch 1406 , thereby reducing the pressure inside the bottle body 1 , which is beneficial to the disassembly of the bottle body 1 .

Specifically, the connection between the lower side of the valve block 11 and the mouth of the bottle body 1 is sealed by a second sealing ring 15 , the second sealing ring 15 is made of rubber material, and the second sealing ring 15 can ensure the sealing of the valve block 11 . The lower side and the mouth of the bottle body 1 are well sealed to prevent water leakage.

As shown in FIGS. 1-5 and 8 , in order to facilitate the rotation of the valve block 11 inside the cover body 2 , specifically, the driving assembly 10 includes a rotating handle 16 , and the rotating handle 16 is fixedly connected to the valve block 11 . The upper end of the handle 16 penetrates the side wall of the cover body 2 and extends to the outside of the cover body 2, and the outer side wall of the cover body 2 is located around the handle 16 and is fixedly connected to a limit block 17. , the side wall of the rotating handle 16 is fixedly connected with a convex block 18, and the convex block 18 is blocked by the limit block 17 in the process of rotating with the rotating plate 16, so the rotation range of the rotating knob 16 is limited, so that the rotating button The two extremes of rotation of 16 are the two different working states of the valve block 11. When the bottle body 1 needs to be disassembled, the rotary handle 16 is rotated, so that the rotary handle 16 will rotate with the valve block 11 to the position shown in Figure 2. At this time, the device can also ensure normal water supply when the bottle body 1 is disassembled. When the water is normally filtered and used, turn the handle 16, so that the handle 16 rotates with the valve block 11 to the state shown in Figure 3 , so the used water is drained to the inside of the bottle body 1 to be filtered by the filter element 3 .

As shown in Figures 9-12, Embodiment 2 is different from Embodiment 1 in that the structure of the drive assembly 10 is changed, that is, the way of rotating the valve block 11 is changed. Back, that is to ensure that the valve block 11 must be rotated when the bottle body 1 is disassembled to change the flow direction of the used water (the used water flows through the through hole 12), and at the same time, in order to ensure that the valve block 11 must also be rotated after the installation is completed. Water can flow through the bottle body 1 during normal operation. Specifically, the drive assembly 10 includes a ring groove 19 , which is opened on the side wall of the bottle body 1 and slides inside the ring groove 19 . A swivel 20 is connected, the outer side wall of the swivel 20 is fixedly connected with a plurality of second blocks 21, the upper and lower sides of the ring groove 19 and the outer side wall of the bottle body 1 are respectively fixedly connected with a first block. The guide block 22 and the second guide block 23, and the first guide block 22 and the second guide block 23 are staggered. A plurality of connecting rods 24 are fixedly connected to the side wall of the pressure relief valve 14. There is a vertical groove on the inner side wall, so that the connecting rod 24 can be separated from the swivel ring 20 and taken out from the inside of the bottle body 1 along with the valve block 11. One end of the connecting rod 24 penetrates the side wall of the bottle body 1 and is connected with the swivel ring. The inner side wall of 20 is movably clamped. It should be noted that although the bottle body 1 has a penetrating position in this embodiment, the sealing position between the valve block 11 and the second sealing ring 15 is lower than this, so the sealing will not be affected. sex.

In the initial state (Fig. 9), when the bottle body 1 is disassembled, the wrench (the one with the slot of the current market manufacturer) is put on the bottle body 1 from the bottom of the bottle body 1, and slides up along the second guide block 23, After sliding onto the second block 21, the wrench is blocked by the first guide block 22. At this time, the wrench must be rotated before the wrench can be slid upward again. Therefore, the wrench slides with the swivel ring 20 during the rotation, and then the swivel ring 20 The valve block 11 is rotated through the clamped connecting rod 24 to the state shown in FIG. 2 . At the same time, after the second clamp block 21 and the first guide block 22 are overlapped (ie, the state shown in FIG. 10 ), the wrench can move along the bottle body 1 . Slide up and finally slide to the first block 5 and make the wrench engage with the first block 5 to drive the connecting piece 4 to rotate to realize the disassembly of the bottle body 1. On the contrary, when the bottle body 1 is installed (from Figure 10 to Figure 9 ), when the wrench slides along the first guide block 22 to the second block 21, the second guide block 23 blocks the wrench from sliding down, so only the wrench with the swivel 20 slides again to the second block 21 and the first block 21. When the two guide blocks 23 overlap, the wrench can be removed, and the valve block 11 will also be driven to the state shown in Figure 3. To sum up, when the bottle body 1 is disassembled and installed, the valve block 11 must be rotated to The bottle body 1 can be disassembled and installed only at the corresponding working position, so as to prevent the operator from forgetting to drive the valve block 11 to rotate to the corresponding working position.

The water channel 7 is communicated. When the device is in use, the valve block 11 is driven to rotate through the drive assembly 10, and then the two Y-shaped water channels 7 are communicated with the two water filter holes 13 respectively. As shown in Figure 3, when using water from the inlet When the inside of the water pipe 8 enters the device, it will flow into the inside of the bottle body 1 from the inside of a water filter hole 13, and then the water is filtered through the filter element 3 inside the bottle body 1, and the filtered water will flow into another filter. The inside of the water hole 13, and eventually flow out of the device from the inside of the water outlet pipe 9;

When the device needs to disassemble and replace the filter element 3, the valve block 11 is first driven to rotate by the drive assembly 10, so the two Y-shaped water channels 7 are disconnected from the two water filtering holes 13, and the two Y-shaped water channels 7 pass through the straight holes. 12 is connected (as shown in Figure 2), at this time, the water entering the device from the water inlet pipe 8 will flow through the straight hole 12 and directly flow out of the device from the inside of the water outlet pipe 9, and then press the pressing block 1404 downward. , so that the pressure inside the bottle body 1 is released from the pressure relief valve 14. At this time, put the wrench on the bottle body 1 and clamp it with the first block 5, and pull the wrench forcefully to make the first block 5 with When the connecting piece 4 is rotated, the connecting piece 4 will be disengaged from the cover body 2 with the continuous rotation of the connecting piece 4 . After removing the filter element 3, the filter element 3 inside the bottle body 1 can be replaced. After replacing the filter element 3, the bottle body 1 can be re-installed under the cover body 2, and the valve block 11 can be reset through the drive assembly 10. .

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the present invention , alternatives and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
