Description

Technical Field

[0001] The present invention relates to the technical field of container cleaning equipment, and in particular to a container cleaner. Background Art

[0002] In daily life, containers are items that are used more frequently. After use, a lot of dirt or residue will accumulate on the inner wall of the container, which needs to be cleaned in time. It is more laborious to clean some small-diameter cylinders or long containers. It is difficult for people's hands to reach the bottom of the cylinder to remove dirt. Therefore, some cleaners that can be used to clean cylinders and other containers have appeared on the market.

[0003] For example, a container cleaner disclosed in Chinese patent publication No. CN201280035400.5 uses liquid pressure to make the base of the rod abut against the opening of the sealing stopper. However, when the liquid pressure is low, the base cannot completely seal the opening, resulting in poor sealing effect and prone to water leakage. When the liquid pressure is too high, when the user presses down on the top rod, the liquid will push the base upward, so the user needs to keep pressing hard, which is laborious and inconvenient to use. In addition, the stopper and the rod are assembled separately, lacking integrated assembly and cannot be pre-assembled, resulting in low production efficiency. Summary of the Invention

[0004] The purpose of this technical solution is to provide a container cleaner, which uses a check valve to open or close the channel, uses an elastic member to ensure the sealing stability of the seal, and improves the problem of poor sealing effect caused by sealing the base of the rod through liquid pressure.

[0005] The purpose of this technical solution is achieved in this way:

[0007] a main body, wherein a passage is provided;

[0008] a nozzle, which is mounted on the main body and has a through hole and a spray hole;

[0009] a check valve, disposed on the main body and configured to open or close the passage;

[0010] Wherein, the check valve comprises:

[0011] a shell, which is inserted into the channel, and a receiving cavity is provided in the shell, wherein the receiving cavity is provided with a water inlet hole communicating with the channel and a water outlet hole communicating with the nozzle;

[0012] a push rod, the lower end of which is movably placed in the accommodating cavity, and the upper end of which passes through the water outlet and extends from the through hole, and the push rod is movable between a first position and a second position;

[0013] a sealing member slidably disposed in the accommodating cavity, with the upper end of the sealing member movably abutting against the lower end of the push rod, the sealing member being used to seal the water inlet or the water outlet;

[0014] an elastic member installed in the accommodating cavity and movably abutting against the sealing member so as to cause the sealing member to have a tendency to move toward the ejector rod;

[0015] When the push rod moves from the first position to the second position under the action of an external force, the push rod overcomes the action of the elastic member to make the sealing member leave the water inlet hole or the water outlet hole;

[0016] When the external force is removed, the elastic member enables the sealing member to move against the water inlet or the water outlet, and enables the sealing member to drive the push rod to move from the second position to the first position.

[0017] Preferably, the housing comprises:

[0018] a housing movably disposed in the main body, the housing being provided with the water inlet hole, and the sealing member being installed in the housing;

[0019] A pressure cap is movably connected to the shell, and the pressure cap is provided with the water outlet hole. The sealing member movably abuts against the lower end of the pressure cap to seal the water outlet hole.

[0021] Preferably, the sealing member is provided with an annular groove, and the annular groove is provided with a sealing ring;

[0022] When the upper end portion of the sealing member is inserted into the water outlet hole, the sealing ring movably abuts against the edge of the water outlet hole.

[0025] Preferably, the pressing cap has an inner hexagonal hole, and the lower end edge of the inner hexagonal hole is the limiting portion.

[0026] Preferably, a plurality of water inlet holes are provided on the side wall of the shell, and a gap exists between the outer wall of the shell and the inner wall of the channel, the gap connecting the water inlet holes and the channel;

[0027] When the push rod is in the second position, liquid enters the accommodating cavity through the water inlet hole and drives the base to move and abut against the upper end of the sealing member.

[0028] Preferably, an abutment boss is provided in the nozzle, the upper end of the pressure cap is turned outward to form a convex edge, a gasket is sleeved on the outer side of the pressure cap, and the gasket is located at the lower end of the convex edge;

[0029] When the housing is installed between the main body and the nozzle, the abutting boss movably abuts against the upper end of the convex edge, and the convex edge enables the gasket to movably abut against the upper end edge of the channel.

[0030] Preferably, the ejector rod comprises:

[0031] A connecting rod is inserted into the pressure cap and the nozzle, and the lower end of the connecting rod has a base, and the lower end of the base is used to movably abut against the sealing member;

[0032] An abutment member is mounted on the upper end of the connecting rod, and the upper end of the abutment member protrudes from the upper end of the nozzle through the through hole, so as to abut against the inner wall of the container.

[0033] Compared with the existing technology, this technical solution has the following outstanding and beneficial technical effects:

[0034] 1. This technical solution uses an integrated check valve to control the opening and closing of the channel. The check valve integrates the push rod, seal and elastic part in a shell, so that the check valve can be produced and assembled as an independent unit, and then assembled with the main structure, which promotes the flexibility and assembly efficiency of the production process, and also provides convenience for subsequent maintenance or replacement; in addition, the built-in elastic part can drive the seal to stably close the water inlet or outlet, thereby ensuring the sealing performance of the check valve and ensuring that the channel is in a sealed state; this integrated design not only optimizes the production and assembly process, but also improves the sealing effect and overall performance of the product.

[0035] 2. This technical solution is designed to provide a water inlet hole on the side wall of the shell. When the push rod is pressed downward, the liquid will enter from the water inlet hole and squeeze the upper end of the base, so that the push rod can remain stable at the lower part of the shell, thereby reducing the force of the user pressing the push rod and ensuring that the liquid can stably flow from the water inlet hole into the water outlet and nozzle.

[0036] 3. The pressure cap designed in this technical solution has an inner hexagonal hole. The lower end of the inner hexagonal hole is not sealed with the upper end of the base, which reduces the design difficulty and precision. The lower end of the inner hexagonal hole serves to limit the ejector pin from popping out of the pressure cap, preventing the base of the ejector pin from separating from the pressure cap, and ensuring the stability of the ejector pin installation.

DETAILED DESCRIPTION

[0042] The specific implementation of this technical solution is further described in detail below with reference to the accompanying drawings. Figures 1-4 .

[0043] A container cleaner comprising:

[0044] The main body 1 is provided with a channel 11 therein for allowing the flow of liquid;

[0045] The nozzle 2 is mounted on the main body 1 and has a through hole 21 and a spray hole 22. After the liquid flows out from the upper end of the channel 11, the liquid is sprayed out from the nozzle 2 through the through hole 21 and the spray hole 22, thereby cleaning the interior of the container.

[0046] a check valve 3 , which is provided on the main body 1 and is used to open or close the passage 11 ;

[0047] Wherein, the check valve 3 includes:

[0048] The housing 31 is inserted into the channel 11 and has a housing 311 therein. The housing 311 has a water inlet 41 communicating with the channel 11 and a water outlet 51 communicating with the nozzle 2. Liquid flows from the channel 11 through the water inlet 41 into the housing 311 and then into the nozzle 2 through the water outlet 51 of the housing 311.

[0049] A push rod 6, the lower end of which is movably disposed in the accommodating cavity 311, and the upper end of the push rod 6 passes through the water outlet 51 and extends out of the upper end of the nozzle 2 from the through hole 21, with a gap between the push rod 6 and the through hole 21 for liquid to flow out. The push rod 6 is movable between a first position and a second position;

[0050] The sealing member 7 is slidably disposed within the accommodating cavity 311 and is used to abut and seal the water inlet hole 41 or the water outlet hole 51, thereby closing the check valve 3 and preventing liquid from flowing from the channel 11 into the nozzle 2. The upper end of the sealing member 7 movably abuts the lower end of the ejector rod 6. The ejector rod 6 and the sealing member 7 are designed as separate parts, which facilitates production, assembly, and replacement.

[0051] An elastic member 32 is mounted in the accommodating cavity 311 and movably abuts against the sealing member 7, causing the sealing member 7 to move toward the push rod 6, thereby maintaining the push rod 6 in the first position. The elastic member 32 also enables the sealing member 7 to maintain abutment and sealing with the water inlet 41 or the water outlet 51. The elastic member 32 is a spring or a disc spring, and in this design, a conical spring is preferably used.

[0052] When the push rod 6 moves from the first position to the second position under the action of an external force, the push rod 6 overcomes the force of the elastic member 32 and moves downward, and the push rod 6 drives the sealing member 7 to move downward in the accommodating cavity 311, so that the sealing member 7 leaves the water inlet hole 41 or the water outlet hole 51, thereby opening the check valve 3 and achieving communication between the channel 11 and the nozzle 2;

[0053] When the external force is removed, under the action of the elastic member 32, the sealing member 7 moves upward and moves against the water inlet hole 41 or the water outlet hole 51, so that the check valve 3 is closed to prevent the liquid from flowing out of the channel 11. At the same time, the sealing member 7 moves upward to drive the push rod 6 to move from the second position to the first position.

[0054] When in use, the container to be cleaned is inverted with the opening facing downward, so that the nozzle 2 is placed in the container, the upper end of the push rod 6 abuts against the bottom of the container, and the container is pressed down to move the push rod 6 downward and drive the sealing member 7 to move downward.

[0055] The housing 31 includes:

[0056] The housing 4 is movably disposed in the main body 1 and is provided with the water inlet 41. The sealing member 7 is installed in the housing 4, with a gap between the side wall of the sealing member 7 and the inner wall of the housing 4.

[0057] The pressure cap 5 is threadedly connected or clamped on the inner wall of the upper end of the shell 4, and the pressure cap 5 is provided with the water outlet 51. The sealing member 7 movably abuts against the lower end of the pressure cap 5 to seal the water outlet 51.

[0058] The lower end of the sealing member 7 is provided with a sliding rod 71, the elastic member 32 is sleeved on the sliding rod 71, and the upper end of the elastic member 32 is movably abutted against the lower end of the sealing member 7, and the lower end of the elastic member 32 is abutted against the bottom of the shell 4. A avoidance hole 42 is provided at the center of the bottom of the shell 4, and the sliding rod 71 is passed through the avoidance hole 42. The sliding rod 71 ensures the stability of the sealing member 7 moving up and down in the shell 4, and prevents the sealing member 7 from shaking left and right and failing to abut against the lower end of the pressure cap 5; when the top rod 6 is in the second position, the elastic member 32 is compressed, and the sealing member 7 is in the lower half of the shell 4. The lower end of the sliding rod 71 passes through the avoidance hole 42 and extends out of the bottom of the shell 4. There is a gap between the sliding rod 71 and the avoidance hole 42 for the flow of liquid, and the liquid can flow into the accommodating cavity 311 from between the sliding rod 71 and the avoidance hole 42.

[0059] The side end of the sealing member 7 is provided with an annular groove 72 , and the annular groove 72 is sleeved with a sealing ring 73 ;

[0060] When the upper end of the sealing member 7 is inserted into the water outlet hole 51, the sealing ring 73 movably abuts the edge of the water outlet hole 51, that is, the sealing ring 73 abuts the lower end of the pressure cap 5, thereby ensuring the sealing of the water outlet hole 51, ensuring the sealing effect, and avoiding the problem of water leakage. At the same time, the sealing ring 73 can be replaced for easy maintenance.

[0061] The lower end of the pressure cap 5 is provided with an inclined surface 511 for guiding the upper end of the sealing member 7 to be inserted into the water outlet 51 . At the same time, the inclined surface 511 abuts against the sealing ring 73 to ensure the sealing effect.

[0062] The upper edge of the sealing member 7 is tilted to facilitate the upper end of the sealing member 7 to be inserted into the water outlet hole 51 .

[0063] A limiting portion 52 is provided on the inner wall of the pressure cap 5, and the lower end of the push rod 6 has a base 611, and the base 611 is placed in the accommodating cavity 311. The upper end of the push rod 6 passes through the pressure cap 5, and the upper end of the base 611 movably abuts against the lower end of the limiting portion 52. The limiting portion 52 prevents the lower end of the push rod 6 from detaching from the accommodating cavity 311, thereby ensuring the stability of the push rod 6 installed on the shell 31, so that the check valve 3 can be produced, transported and assembled separately as a whole.

[0064] The limiting portion 52 is located in the middle of the inner wall of the pressure cap 5, that is, the middle of the inner wall of the water outlet 51. The limiting portion 52 divides the interior of the pressure cap 5 into two parts, an upper part and an lower part. The upper part of the limiting portion 52 is an inner hexagonal hole 53, and the lower end edge of the inner hexagonal hole 53 is the limiting portion 52. When the base 611 abuts against the lower part of the inner hexagonal hole 53, the inner hexagonal hole 53 is not sealed with the base 611. The lower part of the inner hexagonal hole 53 is only used to prevent the push rod 6 from moving upward and detaching from the upper end of the shell 31.

[0065] The interior of the upper end of the pressing cap 5 is an inverted tapered hole, and the lower end of the inverted tapered hole (i.e. the end with the smaller hole diameter) is connected to the upper end of the hexagonal hole 53.

[0066] A plurality of water inlet holes 41 are provided on the side wall of the upper half of the housing 4. A gap exists between the outer wall of the housing 4 and the inner wall of the channel 11, and the gap connects the water inlet holes 41 and the channel 11.

[0067] When the push rod 6 is in the second position, the liquid enters the accommodating cavity 311 through the water inlet hole 41 and flows out from the water outlet hole 51. At this time, the upper end surface of the base 611 is lower than the water inlet hole 41, so that the liquid can contact the upper end surface of the base 611 after entering from the water inlet hole 41, thereby causing the liquid to drive the base 611 to move downward and movably abut against the upper end of the seal 7, ensuring that the seal 7 can be stably located in the lower half of the shell 4. Under the action of the liquid, the force exerted by the user on the container can be relatively reduced, saving effort; the upper end surface of the base 611 is inclined to facilitate the liquid to impact the upper end surface of the base 611, so that the liquid can exert a downward force on the base 611.

[0068] The edge of the lower end face of the seal 7 is tilted upward. When the upper end of the seal 7 abuts the sealed water outlet 51, when liquid enters from the water inlet 41 of the shell 4, the liquid will impact the inclined lower end face of the seal 7, ensuring the force of the seal 7 abutting against the edge of the water outlet 51, further improving the sealing performance of the seal 7.

[0069] The nozzle 2 is provided with an abutting boss 23, the upper end of the pressure cap 5 is turned outward to form a convex edge 54, and a gasket 55 is sleeved on the outer side of the pressure cap 5, and the gasket 55 is located at the lower end of the convex edge 54;

[0070] When the shell 31 is installed between the main body 1 and the nozzle 2, and the nozzle 2 is threadedly connected to the main body 1, the abutment boss 23 movably abuts against the upper end of the convex edge 54, and the convex edge 54 causes the lower end of the gasket 55 to abut against the upper edge of the channel 11, thereby achieving sealing of the connection between the check valve 3, the main body 1 and the nozzle 2.

[0071] The ejector rod 6 comprises:

[0072] A connecting rod 61 is provided in the pressure cap 5 and the nozzle 2, and a base 611 is provided at the lower end of the connecting rod 61. The lower end of the base 611 is used to movably abut against the sealing member 7;

[0073] The abutment member 62 is made of silicone or rubber to avoid scratching the inner wall of the container. The abutment member 62 is engaged with the upper end of the connecting rod 61 through a card slot and a card block, and the upper end of the abutment member 62 protrudes from the upper end of the nozzle 2 through the through hole 21 to abut the inner wall of the container.

[0074] The main body 1 has a base and a tube. A channel 11 is vertically provided in the tube. The lower end of the channel 11 is connected to the base. A receiving hole is opened on the side wall of the base. The receiving hole is used for the water pipe to pass through. The water pipe extends into the base through the receiving hole and is connected to the lower end of the channel 11.

[0075] The lower end of the channel 11 is provided with a clamping device, which includes a clamping jaw seat. The upper end of the clamping jaw seat is provided with a plurality of circumferentially distributed clamping jaws, with a telescopic gap between the clamping jaws. A fastener is sleeved on the outer side of the clamping jaws, and the fastener is used to reduce the telescopic gap, so that the clamping jaws are closer to each other, so that the inner wall of the clamping jaws abuts and fixes against the outer wall of the water pipe head;

[0076] The fastener has an abutment portion inside, which abuts against the outer wall of the clamping jaws, so that the clamping jaws are close to each other. The outer wall of the fastener has an annular groove, and a sealing ring is provided in the annular groove. The fastener is inserted into the lower end of the channel 11, and the outer wall of the sealing ring abuts against the inner wall of the channel 11.
