Filters and controls

Abstract

The present invention relates to a filter and a control mechanism, comprising: a cover body, and a control assembly. When the filter and the control mechanism do not need to purify the water source, the water source enters the cavity inside the mounting block through the first water inlet channel. Then the control assembly is rotated until one end of the control assembly is located between the first water inlet channel and the second water inlet channel. At this time, the flow channel, the first water inlet channel and the first water outlet channel are interconnected, the first water inlet channel and the second water inlet channel are isolated from each other by the control assembly, and the first water outlet channel and the second water outlet channel are isolated from each other by the control assembly. Thereby, the water source can enter from the first water inlet channel and flow out from the first water outlet channel. Therefore, the filter and the control mechanism avoid disassembly on the water supply pipe, and are more convenient to use.

Description

[0001] The invention relates to the technical field of water source purification, and in particular to a filter and a control mechanism. Background Art

[0002] As water pollution becomes increasingly serious, water source filters are often added to water supply pipes. This allows the water in the water supply pipe to be purified and filtered through the water source filter, thereby improving the quality of the water source.

[0026] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0027] like Figures 1 to 4As shown, in one embodiment, a control mechanism includes: a cover body 10 and a control assembly 200. The cover body 10 is provided with a mounting block 100, and a cavity 110 is provided on the mounting block 100, and a first water inlet channel 111, a first water outlet channel 112, a second water inlet channel 113 and a second water outlet channel 114 are provided along the side wall of the cavity 110. The control assembly 200 is rotatably mounted inside the cavity 110. A flow channel 210 for conveying water is provided on the control assembly 200; when one end of the control assembly 200 is located between the first water inlet channel 111 and the second water inlet channel 113, the other end of the control assembly 200 is located between the first water outlet channel 112 and the second water outlet channel 114, and the first water inlet channel 111 is connected to the first water outlet channel 112 through the flow channel 210. The first water inlet channel 111 and the second water inlet channel 113 are isolated from each other by the control assembly 200, and the first water outlet channel 112 and the second water outlet channel 114 are isolated from each other by the control assembly 200. When the water source flows out directly through the flow channel 210 of the control assembly 200, the control assembly 200 is arranged along the axial direction perpendicular to the cavity 110. Specifically, one end of the first water inlet channel 111 is connected to the cavity 110, and the other end of the first water inlet channel 111 is opened at the end of the cover body 10. One end of the first water outlet channel 112 is connected to the cavity 110, and the other end of the first water outlet channel 112 is opened at the end of the cover body 10. One end of the second water inlet channel 113 is connected to the cavity 110, and the other end of the second water inlet channel 113 is opened at the bottom of the cover body 10 and is used to communicate with the sleeve 500 of the filter. One end of the second water outlet channel 114 is connected to the cavity 110, and the other end of the second water outlet channel 114 is opened at the bottom of the cover body 10 and is used to communicate with the inside of the filter element 600 of the filter. Specifically, a resistance plate is also provided on the control component 200. That is, when the control component 200 is installed in the cavity 110, the resistance plate and the bottom of the cavity 110 are in contact with each other, thereby increasing the contact area between the control component 200 and the bottom of the cavity 110. Thereby, the rotation of the control component 200 in the cavity 110 is smoother. At the same time, when the control component 200 is subjected to the impact of the water source, the resistance plate can provide a larger friction force for the control component 200, thereby improving the stability of the control component 200 in the control mechanism.

[0028] In another embodiment, when the water source needs to be introduced into the filter for filtration through the control mechanism, when one end of the control component 200 is located between the first water inlet channel 111 and the first water outlet channel 112, the other end of the control component 200 is located between the second water inlet channel 113 and the second water outlet channel 114. The first water inlet channel 111 is connected to the second water inlet channel 113, and the first water outlet channel 112 is connected to the second water outlet channel 114 through the flow channel 210. Specifically, when one end of the control component 200 is located between the first water inlet channel 111 and the first water outlet channel 112, and the other end of the control component 200 is located between the second water inlet channel 113 and the second water outlet channel 114. That is, the water source can be introduced into the filter for filtration through the control mechanism. More specifically, according to the spacing between the first water inlet channel 111, the first water outlet channel 112, the second water inlet channel 113 and the second water outlet channel 114. A scale value corresponding to the spacing distance is set on the outer edge of the port of the cavity 110, and the user can rotate the control component 200 to a corresponding angle according to the prompt of the scale value, thereby realizing the precise regulation of the water source inside the cavity 110 by the control component 200.

[0029] like Figure 1 and Figure 2As shown, in one embodiment, the control assembly 200 includes a valve stem 220 and a sealing ring 230. The sealing ring 230 is sleeved on the valve stem 220, and the valve stem 220 extends into the cavity 110 and contacts with the side wall of the cavity 110. The valve stem 220 includes a first circulation portion 221, a second circulation portion 222 and a blocking portion 223. One side of the blocking portion 223 is connected to the first circulation portion 221, and the other side of the blocking portion 223 is connected to the second circulation portion 222. The first circulation portion 221, the second circulation portion 222 and the blocking portion 223 are integrally formed. Specifically, after the control assembly 200 is installed in the cavity 110, the side wall of the first circulation portion 221 and the side wall of the second circulation portion 222 both contact with the side wall of the cavity 111. As a result, after the water source enters the cavity 110, it can only flow under the guidance of the flow channel 210. It avoids the turbulence of water source inside the cavity 110 and increases the speed of water source flowing through the control mechanism. One end of the valve stem 220 extends into the cavity 110, and the blocking part 223 located on the valve stem 220 can cooperate with the side wall of the cavity 110. And the blocking part 223 can separate the inside of the cavity 110 into an independent first cavity and a second cavity, and the water source can be effectively blocked and limited by the blocking part 223 after flowing into the cavity 110. Specifically, the sealing ring 230 is sleeved on the valve stem 220, and the sealing ring 230 is an elastic ring or a rubber ring. Thereby, when the control component 200 rotates inside the cavity 110, the valve stem 220 can fully conflict with the side wall of the cavity 110, thereby avoiding the leakage of water source inside the cavity 110.

[0030] In one embodiment, the first flow channel 211 is formed on the first circulation portion 221, and the second flow channel 212 is formed on the second circulation portion 222. When one end of the blocking portion 223 is located between the first water inlet channel 111 and the second water inlet channel 113, the other end of the blocking portion 223 is located between the first water outlet channel 112 and the second water outlet channel 114. The first flow channel 211, the first water inlet channel 111 and the first water outlet channel 112 are interconnected, and the second flow channel 212, the second water inlet channel 113 and the second water outlet channel 114 are interconnected. When one end of the blocking portion 223 is located between the first water inlet channel 111 and the first water outlet channel 112, the other end of the blocking portion 223 is located between the second water inlet channel 113 and the second water outlet channel 114. The first flow channel 211, the first water inlet hole 111 and the second water inlet hole 113 are interconnected, and the second flow channel 212, the first water outlet hole 112 and the second water outlet hole 114 are interconnected. The first circulation part 221 is a first arc plate, and a first opening 301 is provided on the first arc plate, and the water source inside the cavity 110 can enter the first flow channel 211 through the first opening 301. The second circulation part 222 is a second arc plate, and a second opening 302 is provided on the second arc plate, and the water source inside the cavity 110 can enter the second flow channel 212 through the second opening 302. Further, the flow channel 210 is a recess or a channel. That is, the first opening 301 and the second opening 302 are both long openings. Therefore, when the control component 200 rotates, the first flow channel 211 on the first circulation part 221 and the second flow channel 212 on the second circulation part 222 can be more easily connected to the water hole. For example, the first flow channel 211 (or the second flow channel 212), the first water inlet channel 111 and the second water inlet channel 113 are aligned and connected, and the second flow channel 212 (or the first flow channel 211), the second water outlet channel 114 and the first water outlet channel 112 are aligned and connected. Furthermore, the user changes the inclination angle of the first flow channel 211 on the first circulation part 221 relative to the side wall of the cavity 110, and changes the inclination angle of the second flow channel 212 on the second circulation part 222 relative to the side wall of the cavity 110 by rotating the control component 200. In this embodiment, when the blocking part 223 is perpendicular to the axial direction of the cavity 110, the first flow channel 211 (or the second flow channel 212), the first water inlet channel 111 and the first water outlet channel 112 are aligned and connected, and the second flow channel 212 (or the first flow channel 211), the second water inlet channel 113 and the second water outlet channel 114 are aligned and connected. When the blocking portion 223 is parallel to the axial direction of the cavity 110 , the first flow channel 211 (or the second flow channel 212 ), the first water inlet channel 111 and the second water inlet channel 113 are aligned and connected, and the second flow channel 212 (or the first flow channel 211 ), the second water outlet channel 114 and the first water outlet channel 112 are aligned and connected.This embodiment can greatly reduce the rotation angle of the control assembly 200 during regulation by guiding the flow through the first flow channel 211 and the second flow channel 212, thereby making the use of the control mechanism more convenient.

[0031] Specifically, in one embodiment, the control assembly 200 further includes a handle 240. The handle 240 is sleeved on the valve stem 220, and a limiting protrusion 241 is further provided on the side wall of the handle 240, and both ends of the limiting protrusion 241 are used to abut against the cover body 10. A hexagonal bolt is further provided at the end of the valve stem 220, and an inner hexagonal hole adapted to the hexagonal bolt is provided on the handle 240. Further, the limiting protrusion 241 is sleeved on the handle 240, and one end of the limiting protrusion 241 first abuts against the cover body 10. One end of the measuring barrier 223 is rotated from between the first water inlet channel 111 and the first water outlet channel 112 to the required angle between the first water inlet channel 111 and the second water inlet channel 113, and then the other end of the limiting protrusion 241 is correspondingly arranged on the handle 240 according to this angle. That is, the limiting protrusion 241 on the handle 240 starts from one end contacting with the cover body 10, and ends with the other end contacting with the cover body 10; the handle 240 rotates at an angle that satisfies the rotation of one end of the blocking portion 223 from between the first water inlet channel 111 and the first water outlet channel 112 to between the first water inlet channel 111 and the second water inlet channel 113. Therefore, the user can accurately change the flow mode of the water source inside the cavity 110 by simply controlling the contact between the two ends of the limiting protrusion 241 and the cover body 10.

[0032] like Figure 1 and Figure 3As shown, in one embodiment, the control mechanism further includes a first valve body 300 and a second valve body 400. The first valve body 300 is connected to the second valve body 400, the first valve body 300 is installed on the cover body 10, and the first valve body 300 is connected to the mounting block 100. The first valve body 300 is provided with a first opening 301 and a second opening 302. The first opening 301 is connected to the end of the first water inlet channel 111, the second opening 302 is connected to the end of the first water outlet channel 112, and the second valve body 400 is used to be connected to the water supply pipe. The second valve body 400 is provided with a recess 430 and a separation ring 440, and the recess 430 is provided with a first guide hole 410 and a second guide hole 420, the end of the first guide hole 410 is connected to the first opening 301, and the end of the second guide hole 420 is connected to the second opening 302. The separator ring 440 is sleeved on the recess 430, and the first flow guide hole 410 is located inside the separator ring 440, and the second flow guide hole 420 is located outside the separator ring 440. The separator ring 440 is a rubber ring or an elastic ring. A convex portion corresponding to the recess 430 is provided on the first valve body 300. When the first valve body 300 is connected to the second valve body 400, the outer edge of the end of the first flow guide hole 410 can extend into the first opening 301 and connect to the inner edge of the first opening 301. At the same time, the separator ring 440 divides the recess 430 into a water inlet 431 and a water outlet 432. The first opening 301 is provided on the water inlet 431, and the second opening 302 is provided on the water outlet 432. That is, when the water source needs to be filtered by the filter, the raw water first flows from the second valve body 400 through the first valve body 300 and is introduced into the cavity 110, and then the purified water produced after the filtration flows from the cavity 110 through the first valve body 300 and the second valve body 400 in sequence and is discharged. The whole process realizes the separation and transportation of purified water and raw water.

[0033] like Figure 4 As shown, specifically, when the water source needs to be filtered and purified, the water source first enters the control mechanism through the water inlet 431, and the control mechanism guides the water source through the second water inlet channel 113 to the filter for filtering. The clean water produced after filtration is guided out of the filter through the second water outlet channel 114 and enters the control mechanism. Finally, the control mechanism guides the clean water out of the water outlet 432. This avoids the water source of different types from the water inlet 431 to the water outlet 432 from contaminating each other. Figure 5As shown, more specifically, when the water source does not need to be purified, the water source enters the control mechanism through the water inlet portion 431, and the control assembly 200 is rotated to block the first water inlet channel 111 and the second water inlet channel 113 from each other, and to block the second water outlet channel 114 and the first water outlet channel 112 from each other. At this time, only the first water inlet channel 111 and the first water outlet channel 112 are connected inside the cavity 110 of the control mechanism. As a result, the water source can be re-exported without being filtered and purified by the filter after entering the control mechanism.

[0034] In one embodiment, a filter includes the above-mentioned control mechanism, a sleeve 500 and a filter 600. The filter 600 is sleeved inside the sleeve 500, and the sleeve 500 and the filter 600 are both connected to the control mechanism. The filter 600 is a water softening resin and a water softening salt. The sleeve 500 is a transparent sleeve 500. Specifically, in this embodiment, the cover body 10 is provided with a first internal thread and a second internal thread. The sleeve 500 is provided with a first external thread corresponding to the first internal thread, and the filter 600 is provided with a second external thread corresponding to the second internal thread. The user can directly observe the consumption of the water softening resin or the water softening salt on the filter 600 through the sleeve 500, and then replace the water softening resin or the water softening salt in time to ensure the purification efficiency of the filter.

[0035] like Figure 4 and Figure 5As shown, in another embodiment, a plurality of filter holes 610 are provided on the filter element 600. The port of the filter element 600 is connected to the second water outlet channel 114, the second water inlet channel 113 is connected to the casing 500, and the second water inlet channel 113 is located between the filter element 600 and the casing 500. The filter further includes an exhaust member 120. The exhaust member 120 is mounted on the cover body 10, and one end of the exhaust member 120 extends into the casing 500, and the exhaust member 120 is used to control the water pressure inside the casing 500. The filter further includes an isolator 510. A wastewater port is also provided on the casing 500, and the isolator 510 extends into the wastewater port and is connected to the casing 500. The water source first enters the casing 500 through the second water inlet channel 113. A plurality of filter holes 610 are provided at the bottom of the filter element 600. After the water source enters the casing 500, it passes through the filter holes 610 and enters the interior of the filter element 600 for filtration and purification. Then the clean water generated is led out of the casing 500 through the second water outlet channel 114. Specifically, an exhaust member 120 is provided on the cover body 10 of the control mechanism, and the exhaust member 120 is an exhaust screw or an exhaust valve. The exhaust member 120 is used to control the water pressure inside the casing 500, avoid the water pressure inside the casing 500 being too high, and ensure the water flow balance of the water source inside the casing 500 and the filter element 600. More specifically, in this embodiment, the isolation member 510 is an end cover or a piston. When the user processes the wastewater inside the casing 500, there is no need to disassemble and remove the casing 500 from the control mechanism, and the wastewater can be directly discharged from the casing 500 through the wastewater outlet on the casing 500.

[0036] When the filter and control mechanism do not need to purify the water source, the water source enters the cavity 110 inside the mounting block 100 through the first water inlet channel 111. Then rotate the control assembly 200 until one end of the control assembly 200 is located between the first water inlet channel 111 and the second water inlet channel 113. At this time, the flow channel 210, the first water inlet channel 111 and the first water outlet channel 112 are interconnected, the first water inlet channel 111 and the second water inlet channel 113 are isolated from each other by the control assembly 200, and the first water outlet channel 112 and the second water outlet channel 114 are isolated from each other by the control assembly 200. As a result, the water source can enter from the first water inlet channel 111 and flow out from the first water outlet channel 112. Therefore, the filter and control mechanism avoid disassembly on the water supply pipe, and are more convenient to use.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
