Description

Technical Field

[0001] This utility model relates to the field of water purification technology, and in particular to a filter. Background Technology

[0002] Modern households commonly use various water purification devices to deeply treat tap water to ensure the safety and cleanliness of drinking water. These devices, through physical filtration and adsorption purification technologies, effectively remove fine impurities from tap water, significantly improving water quality and meeting people's needs for healthy drinking water. Given the increasingly serious environmental pollution, this point-of-use water purification method has become an important measure to ensure household water safety. For example, using filters (with filter media such as activated carbon, PP cotton, or ultrafiltration media) to filter or ultrafilter tap water, using water softeners to reduce tap water hardness, and using RO membrane water purifiers to obtain highly purified water. However, regardless of whether ultrafiltration, RO membrane water purifiers, or water softeners are used, pre-filtration is essential to remove particulate impurities from tap water.

[0003] For example, Chinese Patent Publication No. CN219517974U discloses a filter, which includes a filtering device and a water flow control valve. The filtering device has a first opening and a second opening. The water flow control valve is connected to the filtering device. The water flow control valve includes a cap and an internal rotor of a valve body. The cap forms a valve cavity, an inlet channel and an outlet channel. The internal rotor of the valve body has a control surface, a first fluid opening, a second fluid opening, a first connecting opening, a second connecting opening, a third connecting opening and a fourth connecting opening. The first connecting opening, the second connecting opening, the third connecting opening and the fourth connecting opening are spaced apart and formed on the control surface of the internal rotor of the valve body.

[0004] The third and fourth connecting openings in the above application are both located on the same side. The water flow needs to turn multiple times to complete the function switch, which can easily lead to a significant increase in fluid resistance, resulting in water pressure loss and a decrease in flow rate. At the same time, the concentration of multiple openings on the same plane requires a more complex sealing structure. Long-term use can easily lead to leakage due to wear of the seals, increasing subsequent maintenance costs.

[0005] Therefore, it is necessary to provide a filter to solve the above-mentioned technical problems. Utility Model Content

[0016] The present invention will be further described below with reference to the embodiments.

[0017] Please see Figure 1-4 This utility model provides a filter, including a bottle body 6, a bottle cap 7 fixed to the top of the bottle body 6, a valve body external support 12 installed inside the bottle cap 7, and an internal valve body rotor 3 that cooperates with the bottle cap 7. The bottle cap 7 has an inlet channel 9, an outlet channel 10 and a drain port 13. The bottle cap 7 has a valve cavity inside and the internal valve body rotor 3 is installed inside. The internal valve body rotor 3 has a first connecting opening, a second connecting opening, a third connecting opening 1 and a fourth connecting opening 2. The third connecting opening 1 is located on the bottom surface of the internal valve body rotor 3, and the fourth connecting opening 2 is located inside the internal valve body rotor. The third connecting opening 1 is located on the bottom surface of the rotor 3 inside the valve body. It can directly connect to the vertical water inlet or sewage outlet channel, reducing fluid turning, reducing bends, reducing fluid resistance, and improving flow efficiency. The fourth connecting opening 2 is located on the side and is used to control the filtration or water supply path. After the water enters from the water inlet channel, the flow direction can be selected according to the rotation angle of the rotor 3 inside the valve body to achieve different working modes. By setting the third connecting opening 1 on the bottom surface of the rotor 3 inside the valve body and the fourth connecting opening 2 on the side surface of the rotor 3 inside the valve body, the number of sealing points on the same plane is reduced, and the risk of leakage is reduced.

[0018] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that a drain channel is provided inside the bottle cap 7. The third connecting opening 1 is connected to the drain channel for pressure relief or backwashing. The fourth connecting opening 2 is connected to the water outlet channel. When the rotor 3 inside the valve body rotates to the pressure relief or backwashing position, the third connecting opening 1 is aligned with the drain channel, and the pressurized water or sewage in the filter device is directly discharged through the bottom opening to avoid residue. When the rotor 3 inside the valve body rotates to the filtration or water supply position, the fourth connecting opening 2 is aligned with the water outlet channel, and the purified water or raw water flows to the water outlet through the side opening.

[0019] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the top of the rotor 3 inside the valve body is connected to a hydraulic valve button 4, and the outside of the bottle cap 7 is provided with a wrench 8 that cooperates with the hydraulic valve button 4. In actual operation, the rotor 3 inside the valve body is rotated by holding the wrench 8, which facilitates the switching and adjustment of the rotor 3 inside the valve body.

[0020] Further as Figure 3 As shown, it is worth noting that an L-shaped channel is provided between the bottom surface of the rotor 3 inside the valve body and the side opening, which is used to connect the third connecting opening 1 and the fourth connecting opening 2. The L-shaped channel connects the third connecting opening 1 on the bottom surface and the fourth connecting opening 2 on the side surface, forming a bypass in a specific working position such as when raw water is supplied, so that the water flow bypasses the filter device and multiple modes can be switched through a single valve core. The L-shaped channel saves space, avoids external piping, and improves durability.

[0021] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that a filter element is installed inside the bottle body 6, and a protruding tube 5 that extends into the filter element is fixed on the rotor 3 inside the valve body.

[0022] Further as Figure 1 As shown, it is worth noting that the surface of the wrench 8 is fitted with a rubber sleeve, and the top of the bottle body 6 is fixed with a cover 11 that covers the outside of the bottle cap 7; in actual operation, the rubber sleeve increases the friction when holding the wrench 8 to prevent slippage.

[0023] In summary: The third connecting opening 1, located on the bottom surface, directly connects to the vertical water inlet or drain channel, reducing fluid detours, bends, and fluid resistance, thus improving flow efficiency. The fourth connecting opening 2, located on the side, controls the filtration or water supply path. After water enters through the inlet channel, the flow direction can be selected according to the rotation angle of the rotor 3 inside the valve body, achieving different operating modes. The third connecting opening 1 is located on the bottom surface of the rotor 3 inside the valve body, while the fourth connecting opening 2 is located on the side surface of the rotor 3 inside the valve body, reducing the number of sealing points on the same plane and lowering the risk of leakage. When the rotor 3 inside the valve body rotates to the pressure relief or backwash position, the third connecting opening 1 and... With the drainage channels aligned, pressurized water or wastewater in the filter device is directly discharged through the bottom opening, avoiding residue. When the rotor 3 inside the valve body rotates to the filtration or water supply position, the fourth connecting opening 2 aligns with the outlet channel, and purified water or raw water flows to the outlet through the side opening. The rotor 3 inside the valve body can be rotated by the provided grip wrench 8, which facilitates switching and adjustment of the rotor 3 inside the valve body. The L-shaped channel connects the third connecting opening 1 on the bottom and the fourth connecting opening 2 on the side, forming a bypass in specific working positions such as raw water supply, allowing the water flow to bypass the filter device. Multiple modes can be switched through a single valve core. The L-shaped channel saves space, avoids external piping, and improves durability.
