Description

Control valve and filling seat for aerosol can
Technical Field
The invention belongs to the technical field of spray cans, and particularly relates to a spray can, a control valve for the spray can and a filling seat cushion for the spray can.
Background
The widely used polyester paints cannot be sprayed by means of the known spray cans, because they are mixed with a modifier (e.g. toluene diisocyanate, etc.), but they solidify after a few hours, so that they cannot be sprayed by the spray cans.
Chinese patent CN104843346A discloses a spray painting aerosol can, which mainly comprises a can body, an accommodating body and a rotating member. When the material to be sprayed is needed to be used, the rotating piece at the bottom of the spray paint aerosol can is rotated, the rotating piece pushes the fragile part of the containing body to break the fragile part, the modifier flows out of the containing body into the can body and is mixed with the material (such as polyester paint) and the like, and therefore the spray paint aerosol can achieve mixing of the material and the modifier when the polyester paint is needed to be used, and the problem that the polyester paint cannot be sprayed and placed with the aid of the spray can is effectively solved. However, the prior art has a series of problems of complex structure, high cost, inconvenient operation, poor sealing performance and the like.
In known spray cans, the spray can includes a control valve, which is also called a spray valve or aerosol valve, and is capable of effectively releasing the material to be sprayed in the spray can after being pushed or compressed. Known control valves are typically sealingly mounted on the lid of the aerosol can and the seal between the control valve and the lid is achieved by means of a sealing gasket disposed therebetween. In addition, the sealing gasket can also realize the sealing between the valve shell and the valve core. However, since the valve housing and the valve core can move relatively, the sealing between the valve housing and the valve core is far from sufficient by only one sealing washer, but the structure used by the known control valve is not accurate to add the sealing washer, so that the known control valve cannot have better sealing performance and safety all the time.
In known spray cans, the can end of the can body is generally domed towards the can end such that its inner surface appears convex and its outer surface appears concave. Although the tank bottom can effectively improve the mechanical strength of the tank body, the curved surface generates an area at the edge (below the convex surface) of the curved surface between the tank bottom and the tank body, and the area is easy to remain almost used up materials to be sprayed, so that the waste of the materials to be sprayed is caused.

Detailed Description
The general principle of the present invention relates to an automatic spray can that can be cultivated. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
Fig. 1 is an axial cross-sectional view of a spray can according to an embodiment of the present invention. As shown in fig. 1, the aerosol can (100) includes a can body (11) and a can lid (12) hermetically connected to the can body (11). The combination of the can body (11) and the can lid (12) is called a pressure-resistant container (10), which is generally made of aluminum alloy, iron, steel or the like and can withstand 15 to 20kg/cm in accordance with the standard2(about 1.5 to 2.0 MPa). In the present embodiment, the can lid (12) and can body (11) are seamed at the juncture of the two. The can lid (12) includes an annular recessed portion (121) and a land portion (122) located therein.
The aerosol can (100) further includes a control valve (20). The control valve (20) is mounted, for example, in a table portion of the can body (11) and is sealingly connected to the can lid (12). The control valve (20) comprises a valve casing (21) arranged in the tank body (11) and connected with the tank cover (12) in a sealing way, and a valve core (22) arranged in the valve casing (21), and is shown in detail in figures 1 and 3. The top end of the valve core (22) axially penetrates the top of the valve casing (21) and the tank cover (12) in a sealing manner, and the bottom end of the valve core axially penetrates the bottom of the valve casing (21). In order to achieve both corrosion resistance and cost of the control valve (20), both the valve housing (21) and the valve body (22) of the control valve (20) can be made of resin. The valve element (22) is movable in its axial direction relative to the valve housing (21) and has a closed position and an open position, wherein the valve element (22) is higher in the open position than in the closed position. When the spool (22) moves from the closed position to the open position, the control valve (20) is in the open state; conversely, when the spool (22) moves from the open position to the closed position, the control valve (20) is in a closed state, as shown in fig. 1 or 3.
The aerosol can (100) also includes a spray cap (not shown) that snaps onto the top end of the valve cartridge (22) and is positioned over the can lid (12). The spray cap is also called a pressing spray cap or a cap type spray cap, and is mainly used for pushing a control valve (20) and spraying and discharging materials to be sprayed.
The spray can (100) further comprises a liner (30) forming an inner liner (31), the liner (30) being generally cylindrical in shape, as shown in detail in figure 1. The inner container 30 is arranged in the tank body (11) and can accommodate the control valve (20). In the present embodiment, the inner liner (31) is made of a breakable material such as aluminum, plastic or glass, but is preferably made of aluminum material and can withstand 15 to 20kg/cm2The pressure of (c). The inner liner (31) may also be constructed of other hard materials that are lightweight and easily punctured. In the embodiment, the inner liner (31), the can cover (12) and the can body (11) are sealed at the top opening of the can body (11) in a rolling way, so that the three are connected in a sealing way, the manufacturing process of the spray can (100) is simplified, and the aim of reducing the cost is fulfilled. Wherein the inner container (30) is used for storing contents, and is usually a modifier, such as toluene diisocyanate for promoting the curing of polyester paint, or other agents for adjusting the physical or chemical characteristics of the material to be sprayed; and the space between the tank body (11) and the inner container (30) is used for storing contents consisting of propellant and propellant, for example, the contents comprise polyester paint and curing agent.
The aerosol can (100) further includes a piercing member (50). The puncture component (50) is arranged in the inner container (31) and is positioned below the valve core (22) so as to be pushed by the valve core (22) to puncture the inner liner (31). The stab member (50) may be constructed of a metal such as steel, aluminum or alloys thereof, but is preferably constructed of a lightweight resin or aluminum alloy. The lancing device (50) shown in fig. 1 is only one embodiment of the lancing device (50), and the lancing device (50) can be selected to have other structures, such as a ram coaxially abutting the valve core (22) and having a pointed bottom end.
For use operation of the spray can (100) according to an embodiment of the present invention. The valve core (22) is pushed by pressing the spray cap, a special press cap (replacing the spray cap) or a slightly soft object, so that the valve core (22) moves towards the bottom (111) of the tank body (11) relative to the valve shell (22), and during the movement, the valve core (22) can push the puncture component (50) to puncture the bottom wall of the lining (31), so that the modifier can flow out of the lining (31) and be mixed with the content in the tank body (11), and thus the material to be sprayed is formed. Then, the valve core (22) is pushed by pressing the spray cap to move relative to the valve shell (22) towards the bottom (111) of the tank body (11), and the material to be sprayed enters the spray cap through the control valve (20) and is sprayed by the spray cap. If the mechanical strength of the spray cap is insufficient, the valve core (22) is pushed for the first time through a special pressing cap or a soft object, so that the spray cap is damaged in the process.
The spray can (100) not only can be used for preparing materials to be sprayed immediately so as to avoid the problem that the polyester paint and the toluene diisocyanate are required to be mixed before the materials are delivered from a factory and the spraying can (100) cannot be used for spraying, but also can trigger the mixing of the polyester paint and the toluene diisocyanate by directly or indirectly pushing the valve core (22). Compared with the prior art, the spraying tank (100) does not need to be additionally provided with a rotating part with a complex structure, and does not need to trigger the mixing of the polyester paint and the toluene diisocyanate through fussy rotating action, so that the spraying tank (100) has the advantages of simple structure, low cost, convenience in operation and the like.
As shown in fig. 1, the lancing member (50) of the present embodiment includes a hollow rod (51), the hollow rod (51) is connected to the valve housing (21) through an adapter sleeve (25) sleeved outside the hollow rod (51), and thus the hollow rod (51) is also connected to the valve core (22). The pushing and sliding of the valve housing (21), the hollow rod (51) and therefore the piercing member (50) with respect to the adapter sleeve (25) will pierce the bottom of the lining (31). Instead of the conventional flow tube in most prior art spray cans, this embodiment of the invention uses a hollow stem (51) and adaptor sleeve (25) to direct the material to be sprayed into the control valve (20). The connection between the adapter sleeve 25 and the valve housing (21) can be selected from a firm screw connection, a snap connection or a welding connection. The connection between the adapter sleeve (25) and the hollow rod body (51) can be an interference fit (also called press fit or friction fit), a clearance fit or a transition fit. Preferably, the longitudinal axes of the hollow rod body (51), the adapter sleeve (25) and the valve housing (21) (vertical axis passing through the bottom in the top of the embodiment shown in fig. 1) coincide in line or approximately coincide.
As shown in fig. 1 and 2, the aerosol can (100) further includes a gravity check valve (251) (also referred to as a check valve, a backflow valve, a holding valve, or a check valve) provided on the adapter sleeve (25). The gravity check valve (251) includes a ball receiving chamber (251d), an inlet (251a), and an outlet (251b) formed on an adapter sleeve (25), and a gravity ball (251c) disposed within the ball receiving chamber (251 d). Wherein, the outlet (251b) is positioned at the bottom of the ball containing cavity (251d), and the inlet (251a) is positioned at the side of the ball containing cavity (251 d). When the bottom of the can body (11) faces the ground (i.e. when the spray can (100) is placed upright during spraying), the gravity ball (251c) moves towards the outlet (251b) under the action of gravity, and then the outlet (251b) is blocked, so that the gravity check valve (251) is forced to close, and further the modifier in the liner (30) (before the liner is not broken) or the material to be sprayed (after the liner is broken) is prevented from entering the control valve (20) through the inlet (251a), the ball containing cavity (251d) and the outlet (251 b). However, when the lid (12) of the spray can (100) is facing the ground (i.e., when the spray can (100) is inverted during spraying), the gravity ball (251c) moves away from the outlet (251b) under the action of gravity, and then opens the inlet (251a) while opening the outlet (251b) to force the gravity check valve (251) to open and allow the modifier or material to be sprayed in the bladder (30) to pass through the inlet (251a), the ball receiving chamber (251d), and the outlet (251b) and then enter the control valve (20), thereby ensuring that the spray can (100) can be sprayed when used in an inverted position. The gravity check valve (251) may be selected from known valves having the same function, in addition to the gravity check valve shown in fig. 2. The bottom of the hollow rod body (51) is provided with a ridge spike (53) extending along the axial direction, so that the bottom wall of the inner container (30) can be conveniently punctured by the puncturing part (50). The spines 53 are pointed sheets, strips, blocks, etc., and the tips thereof are selected to be conical or trapezoidal, etc.
The lancing means (50) further comprises at least one, two or more support members (52) arranged at circumferentially spaced intervals on the side of the hollow rod (51). One end of the supporting component (52) is connected with the hollow rod body (51), and the other end of the supporting component is abutted against the side wall of the inner container (30). The support member (52) and the adaptor sleeve (25) maintain the position of the hollow rod body (51) such that their longitudinal axes overlap along the axis of the inner bladder (30). When the hollow rod body (51) is pushed by the valve core (22), the hollow rod body (51) slides relative to the adapter sleeve 25, so that the edge thorn 53 carried by the hollow rod body pierces a designated part (such as a groove (33) of the inner container (30)) of the inner container (30).
To further facilitate the puncturing of the inner container (30) by the puncturing member (50), one or more pairs of grooves (33) may be provided on the bottom wall of the inner container (30). The groove (33) thins the liner (31) at the bottom wall of the inner container (30) so that the pricking member (50) can easily prick the inner container (30). Preferably, the cross-section of the groove (33) is polygonal, circular, elliptical or annular. If it is desired to puncture the inner container (30) with a hollow rod (51) without the barbs (53), it is advisable to select the grooves (33) as annular or circular grooves that can receive the bottom of the hollow rod (51) completely instead of a pair of grooves, in order to avoid jamming of the hollow rod (51) by the grooves (33). On the other hand, if it is desired to puncture the inner container (30) with a hollow rod (51) having ribs (53), it is advisable to select the recesses (33) as polygonal, circular or oval recesses which are able to receive the ribs (53) completely.
The stabbing member (50) further comprises at least one reinforcing rib (54) axially disposed along an outer wall of the hollow rod body (51). The top of the reinforcing rib (54) is connected to the adapter sleeve (25), and the bottom thereof is connected to the support member (52). When the number of the reinforcing ribs (54) is more than one, the reinforcing ribs (54) are spaced apart along the circumferential direction of the hollow rod body (51).
The thickness of the groove (33) on the bottom wall of the inner container (30) cannot be too thin, otherwise, the inner container (30) is easily crushed by the content in the can body (11); when the thickness of the recess (33) is too large, the inner container (30) is less likely to be punctured by the puncturing member (50). After repeated calculation and mass experiments, the bottom wall of the inner container (31) is preferably made of aluminum material, and the thickness of the groove (33) is 0.1-0.5 mm. More preferably, the thickness of the groove (33) is 0.2 mm.
The aerosol can (100) further includes a reinforcing liner (32) attached within the sidewall of the inner container (30). The reinforcing liner (32) provides support to the liner (30) by increasing the compressive strength of the liner (30). The reinforcing sleeve (32) contributes to the realization: the inner liner (31), the can cover (12) and the edge of the can body (11) are sealed at the top opening of the can body (11). The reinforcing liner 32 is typically constructed of a pressure resistant material. Among them, the pressure-resistant material includes resin, metal, quartz, or the like, but is preferably made of resin having strong corrosion resistance and light weight to impart corrosion resistance to the spray can (100) while reducing the manufacturing cost thereof.
As shown in fig. 3, the valve body (22) includes an upper rod portion (221), a lower rod portion (223), and an enlarged diameter portion (222). The enlarged neck portion (222) is provided between the upper rod portion (221) and the lower rod portion (223). The diameter of the diameter-enlarged portion (222) is larger than the diameter of the upper rod portion (221) and larger than the diameter of the lower rod portion (223). The upper rod part 221 has a discharge passage 221a and seals through the top of the valve housing 21 and the can lid 12 in the axial direction, and the lower rod part 223 has a guide groove 223a and seals through the bottom of the valve housing 21 so that the enlarged diameter part 222 is located inside the valve housing 21. Preferably, the discharge channel 221a includes an outlet provided on the top end surface of the upper stem part 221, and an inlet provided on the side surface of the upper stem part 221. The control valve (20) further comprises an elastic return member (23) provided in the valve housing (21) and located between the diameter-enlarged portion (222) of the valve element (22) and the bottom of the valve housing (21). The elastic return member (23) can be selected from a rubber component, a silicon component, a spring and the like, but is preferably a compression spring sleeved on the lower rod part (223).
When the valve core (22) is pushed to move from the closed position to the open position along the axial direction, the inlet of the discharge passage 221a enters the valve casing (21), the diversion groove (223a) partially moves out of the valve casing (21), so that the material to be sprayed in the inner container (30) can enter the control valve (20) through the diversion groove (223a) and then is discharged out of the control valve (20) by the discharge passage (221 a). When the valve core (22) is pushed for the first time, the valve core (22) can also push the puncture component (50) through the lower rod part (223) of the valve core to puncture the inner container (30). On the contrary, when the valve core (22) is released, the compressed elastic reset component (23) can push the valve core (22) to return to the closing position from the opening position along the axial direction through the diameter expanding part (222), simultaneously withdraw the inlet of the discharge channel (221a) from the valve shell (21), and simultaneously completely move the diversion groove (223a) back to the valve shell (21), thereby preventing the material to be sprayed in the tank body (11) from entering the control valve (20) through the diversion groove (223a) and preventing the material to be sprayed in the control valve (20) from being discharged out of the control valve (20) through the discharge channel (221 a).
The cross section of the diversion trench (233a) can be selected from a circle, an ellipse, a rectangle, a strip or an irregular figure. In this embodiment, however, the guide groove (233a) is preferably a strip-shaped groove extending in the axial direction of the valve element (22), which groove assists the annular gap to better restrict the flow rate of the material to be sprayed and makes it easier to perform the action of moving part of the material out of the valve housing (21) while part of the material remains in the valve housing (21). At least one flow guide groove (223 a). The at least one guide groove (223a) is equally spaced along the circumferential direction of the spool (22). The length of the diversion trench is 8-10 mm, the width is 0.5-1.5 mm, and the depth is 0.3-0.7 mm.
The control valve (20) comprises three seals, wherein one seal is between the valve shell (21) and the tank cover (12) of the aerosol can, the other seal is between the upper rod part (221) of the valve core (22) and the bottom of the valve shell (21), the third seal is between the lower rod part 223 of the valve core (22) and the bottom of the valve shell (21), the three seals are used for improving the sealing performance and the safety of the control valve (20) and the aerosol can, and the risk of leakage of the aerosol can (100) in transportation, use or accidents is greatly reduced. Meanwhile, in order to avoid the influence of the sealing between the lower rod part 223 of the valve core (22) and the bottom of the valve shell (21) on the work of the control valve (20), a diversion groove (223a) is specially arranged on the valve core (22) and can guide the material to be sprayed in the tank body (11) to enter the control valve (20) when the valve core (22) reaches an opening position, so that the control valve (20) can effectively release the material to be sprayed in the aerosol can (100) in time, and the material to be sprayed in the tank body (11) can be prevented from entering the control valve (20) through the diversion groove (223a) when the valve core (22) reaches a closing position. Therefore, the control valve (20) can effectively release the material to be sprayed in the spray can (100) after being pushed, and has better sealing performance and safety.
When the control valve (20) is applied to the spray can (100) of the present embodiment, not only the piercing member (50) can be pushed to pierce the inner container (30), but also the sealing property and safety of the spray can (100) can be improved by the three seals applied thereto.
When the control valve (20) is applied to a known spray can, the sealing and safety of the spray can (100) can be improved by the three seals applied.
In this embodiment, the control valve (20) further comprises a first sealing washer (24) disposed between the resilient return member (23) and the bottom of the valve housing (21) for sealing the resilient return member (23) and the bottom of the valve housing (21). The first sealing gasket (24) plays the role of a gasket, prevents the bottom of the valve shell (21) from being worn, and ensures that the valve shell (21) has enough mechanical strength.
In this embodiment, the control valve (20) further includes a second sealing gasket (26) disposed between the cover (12) and the valve housing (21), the second sealing gasket (26) being for effecting a seal between the cover (12) and the valve housing (21). Preferably, the inner peripheral surface of the second sealing washer (26) is in close contact with the upper stem portion (221) of the valve core (22) so that it simultaneously performs sealing between the tank cover (12) and the valve core (22) and sealing between the tank cover (12) and the valve housing (21).
In this embodiment, an annular gap is provided between the enlarged diameter portion (222) and the valve housing (21). The difference between the inner diameter and the outer diameter of the annular gap is selected to be 0.05-0.3 mm, preferably 0.1mm, so that the flow velocity of the material to be sprayed can be limited and the spraying velocity and the strength of a spraying cap of the spraying tank (100) can be restrained.
As shown in fig. 1, 4 and 5, the spray can (100) further includes a refill seat (60) disposed within the can (11), typically at the bottom of the can (11). FIG. 4 is an axial cross-sectional view of the spray can (100) of FIG. 1 filling the seat (60) and the bottom of the can (11), showing only the bottom of the can (11); fig. 5 shows only a perspective view of the padded seat (60). The can bottom (111) of the can body (11) at the bottom of the can body (11) is generally domed towards the inside of the can body (11) such that the inner surface of the can bottom (111) is convex (111a) and the outer surface is concave (111 b).
The cushion pad (60) is usually made of a hard material such as steel, aluminum, or resin, but may be made of a slightly soft material such as rubber or silicone. For its better quality and lower cost, it is proposed to construct the padded seat cushion (60) with resin.
The filling seat cushion (60) comprises a material-carrying cushion body (62). The material loading cushion body (62) is arranged in the tank body (11) and is positioned on a convex surface (111a) of the tank bottom (111). The material-carrying cushion body (62) can be selected to be the same or similar to a plano-concave lens, a biconcave lens or a concave-convex lens. In order to reduce the manufacturing cost, the material loading cushion body (62) is preferably flat.
As shown in fig. 4, the padded seat cushion (60) includes a first peripheral wall (61). The first peripheral wall (61) is arranged on one side of the material loading cushion body (62) and is connected with the edge of the material loading cushion body (62). The first peripheral wall (61) has the same cross-sectional shape as the can body (11), and the cross-sectional shapes of the can body (11) and the first peripheral wall (61) are generally annular. The first peripheral wall (61) is tightly contacted with (i.e. in interference fit with) the tank body (11) of the pressure-resistant container (10) so as to prevent the material to be sprayed in the tank body (11) from entering the area between the convex surface (111a) of the tank bottom (111) and the tank body (11) and below the material-carrying cushion body (62). The first peripheral wall (61) and the material loading cushion body (62) can keep the material to be sprayed in the tank body (11) above the material loading cushion body (62) under the combined action of the first peripheral wall (61) and the material loading cushion body (62), and the arrangement of the first peripheral wall (61) and the material loading cushion body (62) is convenient for the guide pipe of the existing spraying tank to easily extract the material to be sprayed which is about to be used up from the material loading cushion body (62) even under the condition that the material to be sprayed is about to be used up. Therefore, the filling seat cushion (60) can effectively improve the effective usage amount of the materials to be sprayed in the spraying tank and reduce the residual amount of the materials to be sprayed in the tank body (11).
More importantly, the filling seat cushion (60) keeps the material to be sprayed in the tank body (11) above the material loading cushion body (62), so that the spraying tank (100) of the embodiment can directly use a straight and rigid guide pipe (namely a hollow rod body (51)) to easily extract the material to be sprayed (100) which is about to be used up from the material loading cushion body (62).
In order to further reduce the residual amount of the material to be sprayed in the tank body (11), the first peripheral wall (61) is configured such that the outer diameter thereof gradually increases in the upward direction to form a slope so that the material to be sprayed flows from the first peripheral wall (61) toward the pad body (62). The guide pipe of the spray tank is used for more easily extracting the materials to be sprayed which are about to be used up from the material loading cushion body (62), so that the effective use amount of the materials to be sprayed in the spray tank is further increased, and the residual quantity of the materials to be sprayed in the tank body 11 is more effectively reduced. The thickness of the first peripheral wall (61) is uniform, so that the manufacturing difficulty of the filling seat cushion (60) is reduced, and the cost is saved. That is, the thickness of the first peripheral wall (61) may be uneven regardless of the difficulty and cost of construction. Tests prove that when the firm filling seat cushion (60) is filled, the filling seat cushion (60) can be in good sealing contact with the tank body (11), and the residual quantity of the materials to be sprayed in the tank body (11) can be further reduced.
As shown in FIG. 4, the refill seat cushion (60) further comprises a second peripheral wall 63 provided on the other side of the loading cushion body (62) and connected to the edge of the loading cushion body (62). The second peripheral wall 63 is located on a convex surface (111a) of the tank bottom (11) of the tank body (11) and can support the material loading cushion body (62) to prevent the filling cushion (60) from swinging or turning. Preferably, the second peripheral wall (63) is similar to a round tube, i.e. it has a uniform wall thickness and a constant outer diameter, in order to reduce the load to which the second peripheral wall (63) is subjected in the radial direction.
In this embodiment, the spray can (100) further includes a stirring ball 40 provided in the can body (11).
