Valve structure enabling opening and closing identification

Abstract

Disclosed is a valve structure enabling opening and closing identification. The valve structure comprises: a valve body (10), a knob (30) and a first identification member (50), wherein when the knob (30) rotates and approaches the valve body (10), and when a magnetic attraction force is greater than an elastic force of an elastic member (51), an identification part (501) of the first identification member (50) sinks into a first assembly hole (31) and compresses the elastic member (51) to accumulate force; conversely, when the knob (30) rotates away from the valve body (10), and when the magnetic attraction force is less than an accumulated force of the elastic member (51), the elastic member (51) elastically abuts against the first identification member (50), such that the identification part (501) is exposed from the opening of the first assembly hole (31). By means of determining whether the identification part (501) is exposed from the opening of the first assembly hole (31), whether the valve body (10) is opened or closed is quickly identified, and a user can thus quickly visually identify whether the valve body (10) is opened or closed currently, thereby ensuring usage safety and eliminating dangers.

Description

Valve body structure with switch identification TECHNICAL FIELD

[0001] The present invention relates to a valve body structure, in particular to a valve body structure with switch identification, and more particularly to a valve body structure applied to the field of gas. BACKGROUND

[0002] Gas and natural gas are one of the necessary energy sources for people to live in today's world, which provides the use of stoves and water heaters. However, such energy sources have extremely high risks, so it is often seen in the news that gas explosions, gas leaks, and other disasters occur. The most common cause of these disasters is the condition of the switch, such as not closing the switch properly, forgetting to close the switch, and causing continuous output and leakage of gas, which eventually leads to the aforementioned disasters, which are very costly.

[0003] Therefore, the current manufacturers of switches are committed to so-called safety switches, but they ignore the fact that as long as the switch can be turned in the correct direction to achieve closure, most problems can be prevented. Therefore, the present invention is committed to a new valve body structure that can provide clear identification.

[0004] SUMMARY

[0005] The main purpose of the present invention is to provide users with clear and correct control when operating the switch, to prevent incorrect operation, and to provide users with a visual way to immediately determine the switch status, thereby preventing dangerous situations from occurring. The present invention improves the known technology that the switch is not clear enough for users to identify whether it is open or closed.

[0006] In order to achieve the above object and effect, the present application provides a valve body structure with switch identification, which comprises a valve body, a knob and a first identification member. A set of assembly grooves are formed in the inner top end surface of the valve body. A valve control assembly is arranged and a part of the valve control assembly is assembled in the assembly groove. Another part of the valve control assembly is exposed outside the slot of the assembly groove and a magnetic attraction part is formed in the top end surface of the valve control assembly. The valve control assembly controls the opening and closing of the valve body. The knob is sleeved on the exposed end of the valve control assembly and controls the opening and closing of the valve body by the valve control assembly. The knob is further provided with a first assembly hole which is penetrated from the top end to the bottom end of the knob. The first identification member is movably arranged in the first assembly hole. The first identification member comprises an identification part and a column part. One end of the column part is connected to the bottom end of the identification part and the other end of the column part forms a magnetic attraction part. A spring member is sleeved on the column part. One end of the spring member is elastically abutted against the identification part and the other end of the spring member is elastically abutted against a rib part protruded in the first assembly hole. When the knob is rotated and approaches the valve body, the magnetic attraction part of the column part gradually approaches the magnetic attraction part. When the magnetic attraction force is greater than the elastic force of the spring member, the identification part of the first identification member sinks into the first assembly hole and compresses the spring member to store energy. Conversely, when the knob is rotated and moves away from the valve body, the magnetic attraction part of the column part gradually moves away from the magnetic attraction part. When the magnetic attraction force is smaller than the stored energy of the spring member, the spring member elastically abuts against the first identification member so that the identification part is exposed to the orifice of the first assembly hole. Whether the identification part of the first identification member is exposed to the orifice of the first assembly hole can be used to quickly identify whether the valve body is open or closed.

DETAILED DESCRIPTION

[0019] Please see FIG. 1 to FIG. 6, the present application provides a valve structure with switch identification, which comprises: a valve body 10, a set of assembly grooves 101 is formed by inwardly recessing the top end face of the valve body 10, and a valve control assembly 20 is arranged and a part of the valve control assembly 20 is arranged in the assembly groove 101, another part of the valve control assembly 20 is exposed to the slot of the assembly groove 101 and a magnetic attraction part 201 is formed at the top end face of the valve control assembly 20, the valve control assembly 20 controls the opening and closing of the valve body 10, in addition, the valve body 10 also has a gas inlet part 102, a gas outlet part 103 and a safety valve part 104, the gas inlet part 102 and the gas outlet part 103 are arranged in an open manner inside the valve body 10, and the valve control assembly 20 controls the opening and closing between the gas inlet part 102 and the gas outlet part 103, and the safety valve part 104 is used to protect the gas in the valve body 10 when the gas flows in the valve body 10; a knob 30 is arranged on the exposed end of the valve control assembly 20 and controls the opening and closing of the valve control assembly 20 to the valve body 10, the knob 30 is further provided with a first assembly hole 31 which is penetrated from the top end to the bottom end of the knob 30, and a plurality of finger grooves 32 are recessed around the outer periphery of the knob 30, and each finger groove 32 is designed to provide users with comprehensive grip control.

[0020] A first identification part 50 is movably arranged in the first assembly hole 31, the first identification part 50 comprises an identification part 501 and a column part 502, one end of the column part 502 is connected to the bottom end of the identification part 501, the other end of the column part 502 forms a magnetic attraction part 503, the magnetic attraction part 503 and the magnetic attraction part 201 have magnetic attraction and repulsion action, and a resilient part 51 is arranged on the column part 502, one end of the resilient part 51 is elastically abutted on the identification part 501, and the other end of the resilient part 51 is elastically abutted on a rib part 33 protruded in the first assembly hole 31; wherein when the knob 30 rotates and approaches the valve body 10, the magnetic attraction part 503 of the column part 502 gradually approaches the magnetic attraction part 201, when the magnetic attraction force is greater than the elastic force of the resilient part 51, the identification part 501 of the first identification part 50 sinks into the first assembly hole 31 and stores the elastic force of the resilient part 51; on the contrary, when the knob 30 rotates and moves away from the valve body 10, the magnetic attraction part 503 of the column part 502 gradually moves away from the magnetic attraction part 201, when the magnetic attraction force is less than the stored force of the resilient part 51, the resilient part 51 elastically abuts the first identification part 50, so that the identification part 501 is exposed to the aperture of the first assembly hole 31, and whether the identification part 501 of the first identification part 50 is exposed to the aperture of the first assembly hole 31 is used to quickly identify the opening and closing of the valve body 10.

[0021] According to the above description of the present application, the user can visually check whether the valve body 10 is open or closed before rotating the knob 30, which can prevent unnecessary rotation and protect the service life of the knob 30 and the valve control assembly 20. For specific users (the elderly or the disabled) or in places with poor visibility, the user can also rotate the knob 30 to make the identification part 501 of the first identification member 50 protrude from or sink into the first assembly hole 31, so that the user can feel the position of the first identification member 50 by touch, and then determine whether the current operation is opening or closing. Through the above description, the user can surely open or close the valve body 10, ensure safety and prevent accidents, and also avoid unnecessary rotation of the knob 30, thereby maintaining the service life of the parts of the present application. In addition, when the knob 30 is fully open (in a state where it cannot be rotated), the user is likely to mistakenly judge that it is closed when it cannot be rotated. Therefore, the protruding and sinking states of the first identification member 50 can easily identify the current state without misjudgment.

[0022] In addition to the above-described main technical features of the present application, further technical features and structures of the present application are described below. First, please refer to FIG. 1 and FIG. 4. In order to provide the user with a clearer judgment of whether the valve body 10 is open or closed, the design of the identification part 501 is very important. Therefore, the identification part 501 further includes a direction indication area 501A and a word switch indication area 501B. The direction indication area 501A is arc-shaped and has an arrow end 501C at one end. The word switch indication area 501B is connected to the side of the direction indication area 501A. The end faces of the direction indication area 501A and the word switch indication area 501B are engraved with word patterns 501D. Each word pattern 501D can be concave or convex, so that the user can feel and judge by touch. In addition, the design of the arrow end 501C can provide more explicit control indication and avoid control in the wrong direction.

[0023] In addition, according to the structural features of the first identification member 50 in the above paragraph, the first assembly hole 31 on the knob handle 30 also corresponds to the first identification member 50, so the shape of the first assembly hole 31 corresponding to the direction indication area 501A and the character switch indication area 501B is further distinguished into an arc bending hole area 34 and a round hole area 35, the arc bending hole area 34 and the round hole area 35 are connected and communicated with each other, and the inner wall surface at the connection of the arc bending hole area 34 and the round hole area 35 is provided with corresponding two blocking ribs 36, each blocking rib 36 is clamped in the gap formed between the direction indication area 501A and the character switch indication area 501B, and each blocking rib 36 can be displaced up and down in cooperation with the shape of the connected direction indication area 501A and character switch indication area 501B, in addition, the main purpose is to prevent foreign matter and dirt from entering the first assembly hole 31 to affect the operation of the identification part 501, please see Fig. 4.

[0024] In addition to the above description, in order to assist the elastic member 51 to expose the identification part 501 of the first identification member 50 to the first assembly hole 31 when the knob handle 30 rotates away from the valve body 10, a blocking part 37 is further formed in the first assembly hole 31, when the knob handle 30 gradually rotates away from the valve body 10, normally the rotation of the knob handle 30 will drive the magnetic attraction part 503 of the first identification member 50 to gradually move away from the magnetic attraction part 201, when the distance reaches a certain value, the magnetic attraction force will gradually decrease than the force of the elastic member 51, then the elastic member 51 will push the first identification member 50 upward to expose the identification part 501 to the first assembly hole 31, but when the elastic force of the elastic member 51 is weakened or lost, at this time the blocking part 37 gradually approaches and abuts against the bottom surface of the identification part 501 of the first identification member 50, and the continuous rotation of the knob handle 30 drives the blocking part 37 to push the identification part 501 (not shown in the figure, the pushing of the blocking part 37 is only used when the elastic member 51 loses elasticity), and cooperates with the elastic force of the elastic member 51 to push the first identification member 50 upward, and part of the identification part 501 is exposed to the first assembly hole 31, in this way, the elastic member 51 can still keep the first identification member 50 in the upward exposure action when the elasticity is reduced, please refer to Fig. 6.

[0025] As shown in FIGS. 2, 3, 5, and 6, in order to enable the knob 30 to accurately control the valve control assembly 20 to operate to achieve the conduction and blockage of the gas inlet portion 102 and the gas outlet portion 103, the knob 30 is further provided with a mounting hole 38 at the position sleeved with the valve control assembly 20, and a partition rib 381 is annularly protruded in the mounting hole 38. The partition rib 381 divides the mounting hole 38 into a large-diameter section 382 and a small-diameter section 383. The diameter of the large-diameter section 382 is larger than that of the small-diameter section 383, and the large-diameter section 382 and the small-diameter section 383 are in communication with each other. The portion of the valve control assembly 20 exposed at the slot of the assembly groove 101 is inserted and assembled in the small-diameter section of the mounting hole 38. In addition, a screw 40 is threaded through the knob 30 and locked to the valve control assembly 20. The screw 40 is inserted from the large-diameter section 382 and locked to the valve control assembly 20 at one end. In addition, a gasket 60 is further sleeved between the screw 40 and the partition rib 381, which mainly separates the direct contact between the screw 40 and the partition rib 381 to avoid damage caused by mutual friction.

[0026] In addition, in order to enable the magnetic attraction portion 503 of the first identification member 50 and the magnetic attraction portion 201 of the valve control assembly 20 to accurately perform magnetic action with each other, the magnetic attraction portion 503 of the first identification member 50 can be embedded with a magnet in the column portion 502 or the column portion 502 can be made of metal. In addition, the magnetic attraction portion 201 of the valve control assembly 20 can be embedded with a magnet in the valve control assembly 20 to have magnetism. Therefore, the entire first identification member 50 or only the column portion 502 is made of metal, or the column portion 502 is embedded with a magnet, and the valve control assembly 20 is embedded with a magnet, as long as the magnetic attraction can be generated, which all belong to the protection scope of the present application. Please refer to FIGS. 5 and 6.

[0027] It is also worth mentioning that the present application also has a second embodiment, please see FIG. 7 to FIG. 11, which is different from the first embodiment in that a second assembly hole 39 is further provided on the knob 30, which is penetrated from the top end to the bottom end of the knob 30, and a second identification member 70 is movably arranged in the second assembly hole 39, the second identification member 70 includes a top identification part 701 and a bottom support part 702, one end of the bottom support part 702 is connected to the top identification part 701, and the other end of the bottom support part 702 is normally attached to the top end face of the valve control assembly 20. When the knob 30 is rotated to approach the valve body 10, the bottom support part 702 of the second identification member 70 is attached to the valve control assembly 20, so that the top identification part 701 gradually protrudes from the opening of the second assembly hole 39. Conversely, when the knob 30 is rotated away from the valve body 10, the top identification part 701 of the second identification member 70 gradually sinks into the second assembly hole 39. The top identification part 701 further distinguishes a direction indicating area 703 and a switch indicating area 704, the switch indicating area 704 is connected to one side of the direction indicating area 703, and one end of the direction indicating area 703 forms an arrow end 705, the indicating direction of the arrow end 705 is opposite to the arrow end 501C. The second assembly hole 39 is further divided into an upper hole area 391 and a lower hole area 392 in cooperation with the direction indicating area 703 and the switch indicating area 704, the upper hole area 391 and the lower hole area 392 are in communication with each other. In addition, two corresponding protruding ribs 393 are protruded on the inner wall surface at the connection between the upper hole area 391 and the lower hole area 392, each protruding rib 393 is clamped in the gap between the direction indicating area 703 and the switch indicating area 704, and a ring rib 394 is protruded on the inner wall of the lower hole area 392 of the second assembly hole 39. The bottom end of the bottom support part 702 of the second identification member 70 is provided with a cross section 706, the bottom support part 702 is penetrated from the lower hole area 392 and is attached to the ring rib 394. The position of the bottom support part 702 with the cross section 706 is compressed and deformed, so that after one end of the bottom support part 702 with the cross section 706 penetrates through the ring rib 394, it is elastically reset and limited in the lower hole area 392.

[0028] The second embodiment of the present application can provide more judgment criteria for users in identification. Even if the elastic member 51 does not have elasticity and the first identification member 50 cannot operate, at least the second identification member 70 can still operate normally to provide identification. Finally, a control groove 401 is further formed on the top end face of the screw 40, which can be a character type, a cross type or a rice type. It mainly provides various hand tools to control the tightness between the knob 30 and the valve control assembly 20, so as to make the rotation of the knob 30 more smooth.
