CLEANING SUBSTANCE QUANTITATIVE DISTRIBUTION DEVICE FOR NON-QUANTITATIVE VALVETECHNICAL FIELD
[0001] The present invention relates to the field of cleaning substance distributors, and particularly, to a cleaning substance quantitative distribution device for a non-quantitative valve.BACKGROUND
[0002] At present, push-type injection valve used in an aerosol can on the market is a non-quantitative valve. When the injection valve is in a pre-pressed state, contents in the aerosol can are in a continuously injected state. Traditional manual distribution device used in the aerosol can is unable to realize a quantitative distribution function, and an injection amount of the contents can only be controlled according to a duration in which the injection valve is pressed, leading to a great waste of the contents in the aerosol can. Although there are some distribution devices capable of realizing quantitative distribution on the market, the distribution devices are complicated in structure, cannot be matched with existing push-type non-quantitative injection valves, and cannot realize injection amount adjustment.
[0003] SUMMARY
[0004] It is an object of the embodiments of the present invention to provide a cleaning substance quantitative distribution device for a non-quantitative valve to solve one or more technical problems in the prior art, and at least provide a beneficial selection or creation condition.
[0005] A technical solution used to solve the above technical problems is as follows.
[0006] The present invention provides a cleaning substance quantitative distribution device for a non-quantitative valve. The device includes a shell, an elastic injection valve provided with a pressing end, and a pressing assembly. The pressing assembly includes a pressing wheel, a pressing block resettably mounted on the shell in a reciprocating sliding mode through an elastic member, and a unidirectional transmission structure in transmission connection between the pressing wheel and the pressing block. The reciprocating sliding of the pressing block includes a pressing motion and a resetting motion which are opposite to each other. The unidirectional transmission structure is used for enabling the pressing block to drive the pressing wheel to rotate unidirectionally in the pressing motion, and stop the pressing wheel in the resetting motion. A plurality of pressing portions are annularly arranged at intervals on an outer periphery of the pressing wheel to sequentially abut against and press the pressing end to enable the elastic injection valve to inject.
[0007] The present invention has the beneficial effects as follow. When in use, the elastic injection valve is mounted at a can opening of an aerosol can. When it is necessary to inject a cleaning substance in the aerosol can in a quantitative distribution mode, the pressing block is pressed. When the pressing block makes the pressing motion from a free state, the pressing wheel is driven to rotate unidirectionally through the unidirectional transmission structure. The rotated pressing wheel sequentially abuts against and presses the pressing end on the elastic injection valve through the plurality of pressing portions on the outer periphery. During this process, the elastic injection valve realizes one or more injection opening actions, which means that quantitative distribution is realized. However, after the pressing block is pressed, the pressing block moves back to make the resetting motion under an action of a reset elasticity of the elastic member. During this process, the pressing wheel is in a stop state. The pressing end does not perform a pressing operation at the moment, and the elastic injection valve does not perform an injection action. That is to say, the elastic injection valve realizes quantitative distribution once in a working cycle of each reciprocating sliding of the pressing block, thereby avoiding continuous pressing and continuous injection, reducing the waste of cleaning substance, and improving user experience.
[0008] As a further improvement of the above technical solution, the unidirectional transmission structure includes a driven shaft rotatably mounted in the shell, a unidirectional bearing and a driven wheel sleeved on the driven shaft. The pressing wheel is sleeved on the unidirectional bearing, and the driven wheel is in transmission connection with the pressing block.
[0009] In the solution, when the pressing block is pressed and pushed, the pressing wheel on the driven shaft is driven to rotate by driving the driven wheel to rotate. The pressing wheel is mounted on the driven shaft through the unidirectional bearing, so that the pressing wheel may be driven to rotate unidirectionally through the unidirectional bearing when the driven shaft rotates in one direction, while the pressing wheel stops under the abutting of the pressing end when the driven shaft rotates in the other direction. That is to say, the driven wheel rotates relative to the pressing wheel without affecting the resetting motion of the pressing block, so that in one reciprocating cycle of the pressing block, the pressing wheel can only be driven to rotate in a previous stage of the pressing motion. When operated by user, the pressing motion of the pressing block is controlled to a higher extent, which is equivalent to realizing quantitative distribution once the pressing block is pressed, regardless of a duration of pressing; and even if the pressing block is pressed all the time, the elastic injection valve will not be opened to inject.
[0010] As a further improvement of the above technical solution, the driven wheel is a gear, and the pressing block is provided with a rack meshed with the driven wheel.
[0011] In the solution, the pressing block is meshed with teeth on an outer periphery of the driven wheel through the rack to realize transmission, so that the meshed transmission between the rack and the gear may guarantee that no slippage occurs.
[0012] As a further improvement of the above technical solution, the elastic member is a spring, and at least one of the pressing block and the shell is provided with a protruding column sleeved with the spring.
[0013] In the solution, the elastic member is the spring, and two ends of the spring respectively act on the pressing block and the shell. In order to avoid the spring from inclining away during pressing, the protruding column is arranged to position the spring.
[0014] As a further improvement of the above technical solution, the pressing block includes a pressing head extending out of the shell, and two sliding arms connected to an inner end of the pressing head side by side at an interval. The spring is vertically arranged between the two sliding arms slidably extends into the shell.
[0015] In the solution, the pressing block is formed by connecting the pressing head and the two sliding arms. The pressing head extends out of the shell, while the two sliding arms slidably extend into the shell. The two sliding arms may also limit and mount the spring located therebetween.
[0016] As a further improvement of the above technical solution, a side surface of the sliding arm is provided with a sliding groove, and a guide block in slidable limit fit with the sliding groove is fixed in the shell.
[0017] In order to avoid the pressing block from slipping out of the shell, in the solution, the guide block is arranged in the shell to be in slidable limit fit with the sliding groove on the side surface of the sliding arm.
[0018] As a further improvement of the above technical solution, the pressing portion has an arc-shaped convex structure, and an outer side surface of the pressing portion is provided with an arc-shaped abutting surface. In the solution, the pressing portion has the arc-shaped convex structure, and the pressing portion abuts against the pressing end through the arc-shaped abutting surface, so that the above configuration may guarantee that under the condition that the pressing portion may push the pressing end when rotating. Therefore, the pressing end may smoothly jump on the next pressing portion, and it is convenient for operation and avoiding jamming.
[0019] As a further improvement of the above technical solution, the elastic injection valve is provided with an elastic reset valve core, and a pressing swing arm rotatably mounted on an outer side of the elastic injection valve. One end of the pressing swing arm is connected with the elastic reset valve core, and the other end of the pressing swing arm is the pressing end.
[0020] In the solution, the elastic reset valve core is driven to move by swinging the pressing swing arm, in order to realize the injection action of the elastic injection valve. Two ends of the pressing swing arm respectively act on an end portion of the elastic reset valve core and the pressing portion of the pressing wheel, and a swing center of the pressing swing arm is arranged between the two ends, so that lighter pressing and a labor-saving effect are achieved. Moreover, a position of the pressing swing arm in a free state is determined according to a size of the pressing wheel, in order to ensure that the pressing end is located between two adjacent pressing portions in the free state, thereby guaranteeing that the elastic injection valve is in a closed state after each pressing.
[0021] As a further improvement of the above technical solution, the pressing assembly further includes an injection amount adjusting structure for adjusting a reciprocating sliding stroke of the pressing block.
[0022] In the solution, the injection amount adjusting structure is also arranged to adjust an injection amount by a specific way of adjusting the reciprocating sliding stroke of the pressing block. Because the reciprocating sliding stroke of the pressing block is related to a rotation angle of the pressing wheel, the reciprocating sliding stroke of the pressing block is extended when a large injection amount is required, while the reciprocating sliding stroke of the pressing block is shortened when a small injection amount is required.
[0023] As a further improvement of the above technical solution, the injection amount adjusting structure includes an adjusting block slidably mounted in the shell. The adjusting block is provided with a first gear position at a tail end of a reciprocating sliding track of the pressing block, and a second gear position on an outer side of the reciprocating sliding track of the pressing block.
[0024] In the solution, the reciprocating sliding stroke of the pressing block is adjusted through the adjusting block. When the reciprocating sliding stroke of the pressing block needs to be shortened, the adjusting block is pushed to the tail end of the reciprocating sliding track. When the pressing block is pressed to move to the tail end, an end portion of the pressing block may be blocked by the adjusting block, thereby shortening a stroke in which the pressing block is pressed. When the reciprocating sliding stroke of the pressing block needs to be extended, the adjusting block is pushed to the outer side of the reciprocating sliding track.
[0025] In other solutions, the adjusting block may be a multi-step structure. According to different requirements, the adjusting block is pushed to a preset position to make corresponding step block the pressing block, thereby realizing multi-gear-position adjustment.BRIEF DESCRIPTION OF DRAWINGS

[0037] In the description of the present invention, unless otherwise explicitly defined, the terms “setting” , “mounting” and “connecting” should be understood a broad sense, and those having ordinary skill in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solution.
[0038] With reference to FIG. 1 to FIG. 7, the following embodiments are made for a cleaning substance quantitative distribution device for a non-quantitative valve of the present invention.
[0039] In the embodiment, the cleaning substance quantitative distribution device includes: a shell 100, an elastic injection valve 200 mounted in the shell 100 and a pressing assembly.
[0040] The shell 100 includes a base, a front shell sleeved on a front side of the base and a rear shell sleeved on a rear side of the base. Both the front shell and the rear shell are connected to the base through a screw, so that the front and rear sides inside the base 100 form a mounting cavity.
[0041] The elastic injection valve 200 is mounted on the rear side inside the base. The elastic injection valve 200 has an inlet end and an outlet end. A wall body of the shell 100 is correspondingly provided with a through hole for the inlet end and the outlet end to penetrate through. When in use, as shown in FIG. 2, the inlet end of the elastic injection valve 200 is in fluid connection with a can opening of an aerosol can.
[0042] As shown in FIG. 4, the elastic injection valve 200 is also provided with a pressing end 210. The elastic injection valve 200 may inject by pressing the pressing end 210. In the embodiment, the elastic injection valve 200 includes a valve body, an elastic reset valve core mounted in the valve body and a pressing swing arm 220. A specific structure of an interior of the valve body and the elastic reset valve core is the prior art. That is to say, the elastic injection valve 200 may inject by operating the elastic reset valve core. It is equivalent to an existing pressing pump structure. A hinged portion hinged with an outer side of the valve body is arranged between two ends of the pressing swing arm 220. One end of the pressing swing arm 220 is connected with an outer end of the elastic reset valve core, and the other end of the pressing swing arm 220 is set as the pressing end 210. The elastic reset valve core is driven to move by swinging the pressing swing arm 220, in order to realize an injection action of the elastic injection valve 200. A swing center of the pressing swing arm 220 is arranged between the two ends, so that lighter pressing and a labor-saving effect are achieved.
[0043] The pressing assembly includes a pressing wheel 300, a pressing block 400 and a unidirectional transmission structure. The pressing wheel 300 and the elastic injection valve 200 are arranged on the same side. The pressing block 400 is slidably mounted in the shell 100. An elastic member is arranged between the pressing block 400 and the shell 100, so that the pressing block 400 may resettably perform reciprocating sliding in the shell 100. The reciprocating sliding of the pressing block 400 includes a pressing motion and a resetting motion which are opposite to each other. The pressing motion means that the pressing block 400 is pressed inwardly by an external force, and the elastic member is elastically deformed to store energy at the moment; while the resetting motion means that the pressing block 400 is released after being pressed, and automatically moves back under an action of a reset elasticity of the elastic member.
[0044] The unidirectional transmission structure connects the pressing block 400 with the pressing wheel 300. The unidirectional transmission structure may enable the pressing block 400 to drive the pressing wheel 300 to rotate unidirectionally in the pressing motion, and enable the pressing block 400 to stop the pressing wheel 300 in the resetting motion. That is to say, the pressing wheel 300 can only be driven to rotate in the pressing motion within one cycle in which the pressing block 400 is pressed.
[0045] In the embodiment, a plurality of pressing portions 310 are arranged on an outer periphery of the pressing wheel 300. The plurality of pressing portions 310 are annularly arranged at intervals to sequentially abut against and press the pressing end 210 to enable the elastic injection valve 200 to inject.
[0046] In the embodiment, the pressing block 400 includes an integrally formed pressing head 430, and two sliding arms 440 connected to an inner end of the pressing head 430 side by side at an interval. The pressing head 430 extends out of the shell 100, while the two sliding arms 440 slidably extend into the shell 100. In the embodiment, the elastic member is a spring 800. Two ends of the spring 800 respectively act on the pressing block 400 and the shell 100. The spring 800 is vertically arranged between the two sliding arms 440. One end of the spring 800 acts on the inner end of the pressing head 430, while the spring 800 acts on an abutting platform inside the shell 100. In the embodiment, the inner end of the pressing head 430 is provided with a protruding column 420, which is sleeved with the spring 800 to position the spring 800, thereby avoiding the spring 800 from inclining away during pressing. The two sliding arms 440 may also limit the spring 800 located therebetween during an installation process.
[0047] In other embodiments, the protruding column 420 may be arranged on the abutting platform inside the shell 100, or the abutting platform and the pressing head are both provided with the protruding column 420.
[0048] In order to avoid the pressing block 400 from sliding out of the shell 100, a sliding groove 441 is provided on a side surface of the sliding arm 440. A guide block 110 is fixed in the shell 100, and in slidable limit fit with the sliding groove 441.
[0049] When it is necessary to inject a cleaning substance in an aerosol can in a quantitative distribution mode, the pressing block 400 is pressed. When the pressing block 400 makes the pressing motion from a free state, the pressing wheel 300 is driven to rotate unidirectionally through the unidirectional transmission structure. The rotated pressing wheel 300 sequentially abuts against and presses the elastic pressing end 210 on the elastic injection valve 200 through the plurality of pressing portions 310 on the outer periphery. During this process, the elastic injection valve 200 realizes one or more injection opening actions, which means that quantitative distribution is realized. However, after the pressing block 400 is pressed, the pressing block moves back to make the resetting motion under an action of a reset elasticity of the elastic member. During this process, the pressing wheel 300 is in a stop state. The elastic pressing end 210 does not perform a pressing operation at the moment, and the elastic injection valve 200 does not perform an injection action. That is to say, the elastic injection valve 200 realizes quantitative distribution once in a working cycle of each reciprocating sliding of the pressing block 400, thereby avoiding continuous pressing and continuous injection, reducing the waste of cleaning substance, and improving user experience.
[0050] In the embodiment, the unidirectional transmission structure includes a driven shaft 500, a unidirectional bearing 600 and a driven wheel 700. The driven shaft 500 is rotatably mounted in the shell 100. The unidirectional bearing 600 and the driven wheel 700 are respectively sleeved at two ends of the driven shaft 500. The pressing wheel 300 is sleeved on the unidirectional bearing 600. The driven wheel 700 is in transmission connection with the pressing block 400.
[0051] When the pressing block 400 is pressed and pushed, the pressing wheel 300 on the driven shaft 500 is driven to rotate by driving the driven wheel 700 to rotate. The pressing wheel 300 is mounted on the driven shaft 500 through the unidirectional bearing 600. When the driven shaft 500 rotates in one direction, the pressing wheel 300 may be driven to rotate unidirectionally through the unidirectional bearing 600. When the driven shaft 500 rotates in the other direction, the pressing wheel 300 stops under the abutting of the elastic pressing end 210. That is to say, the driven wheel 700 rotates relative to the pressing wheel 300 at the moment, without affecting the resetting motion of the pressing block 400, so that in one reciprocating cycle of the pressing block 400, the pressing wheel 300 can only be driven to rotate in a previous stage of the pressing motion. The user has a higher degree of control over the pressing motion of the pressing block 400. It is equivalent to realizing quantitative distribution once the pressing block 400 is pressed, regardless of a duration of pressing; and even if the pressing block 400 is pressed all the time, the elastic injection valve 200 will not be opened to inject.
[0052] For the transmission connection between the driven wheel 700 and the pressing block 400, in the embodiment, the driven wheel 700 is a gear, while the pressing block 400 is provided with a rack 410 meshed with the driven wheel 700.
[0053] In other embodiments, the driven wheel 700 and the pressing block 400 may be a transmission structure including a friction wheel and a friction surface, and a linear motion of the pressing block 400 may also be converted into the rotation of the driven wheel 700.
[0054] In the embodiment, the pressing block 400 is meshed with teeth on an outer periphery of the driven wheel 700 through the rack 410 to realize transmission. The meshed transmission between the rack 410 and the gear may guarantee that no slippage occurs.
[0055] In the embodiment, the pressing portion 310 has an arc-shaped convex structure. An outer side surface of the pressing portion 310 is provided with an arc-shaped abutting surface. The pressing portion 310 abuts against the elastic pressing end 210 through the arc-shaped abutting surface, which may guarantee that under the condition that the pressing portion 310 may push the elastic pressing end 210 when rotating, so that the elastic pressing end 210 may smoothly jump on the next pressing portion 310, thereby being convenient for operation and avoiding jamming.
[0056] A position of the pressing swing arm 220 in a free state is determined according to a size of the pressing wheel 300, in order to ensure that the pressing end 210 is located between two adjacent pressing portions 310 in the free state, thereby guaranteeing that the elastic injection valve 200 is in a closed state after each pressing.
[0057] Further, the pressing assembly includes an injection amount adjusting structure for adjusting a reciprocating sliding stroke of the pressing block 400. Because the reciprocating sliding stroke of the pressing block 400 is related to a rotation angle of the pressing wheel 300, the reciprocating sliding stroke of the pressing block 400 has to be extended if a large injection amount is required, while the reciprocating sliding stroke of the pressing block 400 has to be shortened if a small injection amount is required.
[0058] The injection amount adjusting structure includes an adjusting block 900, slidably mounted in the shell 100. In order to be convenient for operation, a wall body of the shell 100 is provided with an operating groove, in which a toggle member provided in the adjusting block 900 is arranged.
[0059] Two ends of a sliding track of the adjusting block 900 are respectively provided with a first gear position in which the adjusting block 900 is pushed to a tail end of the reciprocating sliding track of the pressing block 400, and a second gear position in which the adjusting block 900 is pushed to an outer side of the reciprocating sliding track of the pressing block 400.
[0060] As shown in FIG. 5, FIG. 6 and FIG. 7, in the embodiment, the reciprocating sliding stroke of the pressing block 400 is adjusted through the adjusting block 900. When the reciprocating sliding stroke of the pressing block 400 needs to be shortened, the adjusting block 900 is pushed to the tail end of the reciprocating sliding track. When the pressing block 400 is pressed to move to the tail end, an end portion of the pressing block 400 may be blocked by the adjusting block 900, thereby shortening a stroke in which the pressing block 400 is pressed. When the reciprocating sliding stroke of the pressing block 400 needs to be extended, the adjusting block 900 is pushed to the outer side of the reciprocating sliding track.
[0061] In other solutions, the adjusting block 900 may has a multi-step structure. According to different requirements, the adjusting block 900 is pushed to a preset position to make corresponding step block the pressing block 400, thereby realizing multi-gear-position adjustment.
[0062] The above describes some embodiments of the present invention in detail, but the present invention is not limited to the embodiments. Those having ordinary skill in the art may further make various equivalent modifications or substitutions without violating the essential of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present application.
