Technical Field

[0001] The present invention relates to a leak repair kit for repairing leaks in an object, a mixing device for mixing leak repair fluid with compressed air, a leak repair method for repairing leaks in an object, and a mixing method for mixing leak repair fluid with compressed air. Background Technology

[0002] Previously, leak repair kits for repairing leaking objects such as tires were known. For example, Patent Document 1 below discloses a leak repair kit for repairing leaks by sequentially injecting leak repair fluid and compressed air into the leaking object using compressed air from a compressor.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2017-056662

[0004] However, in the leak repair kit of Patent Document 1, the leak repair fluid pressurized by compressed air is discharged in a straight line into the interior of the leaking object, resulting in a situation where the leak repair fluid remains in a portion of the object's interior. When the inner surface of the object has an uneven structure, such leak repair fluid sometimes has difficulty reaching the leaking area, thus further improvement is desired. Summary of the Invention

[0005] The present invention was made in view of the above-mentioned actual situation, and its main object is to provide a leak repair kit, a mixing device, a leak repair method and a mixing method that can efficiently repair leaks even when the inner surface of an object has an uneven structure.

[0006] The present invention provides a leak repair kit for repairing leaks in an object, comprising: a container containing a leak repair fluid; a compressed air source for supplying compressed air; a mixing device installed in the container for generating a mixture of the leak repair fluid and the compressed air; a first connector connecting the compressed air source to the mixing device; and a second connector connecting the mixing device to the valve of the leaking object, wherein the non-aerosolized and non-foamed mixture is discharged from the valve into the interior of the object at a radial angle of 20° or more.

[0007] The leak repair kit of the present invention, by having the above-described configuration, enables efficient leak repair even when the inner surface of the object has an uneven structure. Attached Figure Description

[0013] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0014] Figure 1 This is a perspective view conceptually representing the leak repair kit 1 of this embodiment. (See diagram below.) Figure 1 As shown, the leak repair kit 1 is suitable for filling leak repair fluid R and compressed air A into an object T such as a leaking tire.

[0015] The leak repair kit 1 of this embodiment includes: a bottle unit 2 for supplying a mixture of leak repair fluid R and compressed air A, and a compressed air source 3 for supplying compressed air A. The compressed air source 3 is, for example, a compressor. The compressed air source 3 generates compressed air A by being powered, for example, via a flexible cord 3a connected to an external power source. Such a compressed air source 3 can supply a large amount of compressed air A in a small size and has excellent storage capacity when not in use.

[0016] Figure 2 This is a cross-sectional view showing an example of bottle unit 2. For example... Figure 2 As shown, the bottle unit 2 of this embodiment includes a mixing device 4 for mixing leak repair fluid R with compressed air A, and a container 5 containing the leak repair fluid R. The mixing device 4 includes, for example, an adapter component 6 mounted on the container 5, and a cap component 7 mounted on the adapter component 6.

[0017] Such a bottle unit 2 facilitates the installation of the mixing device 4 and container 5, helping to shorten the time required for leak repair. Furthermore, the mixing device 4 can pre-mix the leak repair fluid R and compressed air A before filling the object T, further reducing the time required for leak repair. Moreover, the mixing device 4 is not limited to this type; for example, it can also be a one-piece molded product integrating the adapter component 6 and the cap component 7.

[0018] Container 5, for example, has an opening 5a for containing leak repair fluid R inside container 5. Container 5, for example, receives leak repair fluid R from the opening 5a. The opening 5a, for example, has a membrane (not shown) for maintaining the contained leak repair fluid R as airtight. A mixing device 4 is preferably installed at the opening 5a of container 5. Such a container 5 does not require a separate outlet for leak repair fluid R, which helps reduce manufacturing costs.

[0019] The mixing device 4 of this embodiment includes a mixing chamber 8 having a space for mixing leak repair fluid R with compressed air A. The mixing chamber 8 includes, for example, a top surface 8a located above, a bottom surface 8b located below, and a side surface 8c connecting the top surface 8a and the bottom surface 8b when the mixing device 4 is installed in the container 5 for leak repair. The mixing chamber 8 has, for example, a cylindrical space with a circular top surface 8a and a circular bottom surface 8b.

[0020] The mixing device 4 of this embodiment includes a first inlet 9 for supplying compressed air A to the mixing chamber 8, and a second inlet 10 for supplying leak repair fluid R to the mixing chamber 8. The first inlet 9 is connected, for example, to a compressor that serves as the compressed air source 3. The second inlet 10 is preferably directly connected to the container 5. By pulsating the compressed air A supplied from the compressor that serves as the compressed air source 3, the mixing chamber 8 is repeatedly subjected to positive and negative pressure states, thereby enabling the leak repair fluid R in the container 5 to drip from the second inlet 10 into the mixing chamber 8 to generate a mixture.

[0021] The preferred mixture of leak repair fluid R and compressed air A is generated in a state where it is neither aerosolized nor foamed. Such a mixture, as an unaerosolized mixture with a particle size of leak repair fluid R exceeding 100 μm, can be supplied to the object T, suppressing the suspension of leak repair fluid R within the object T. Furthermore, because the leak repair fluid R does not foam, this mixture exhibits excellent flowability within the object T, facilitating rapid movement of the leak repair fluid R to the leaking portion via the pre-spinning process S4 described later. Here, the particle size of the leak repair fluid R contained in the mixture is its diameter if the particle shape is spherical, and its maximum length if the particle shape is not spherical.

[0022] The non-aerosolized mixture preferably has a particle size of the leak repair fluid R exceeding 500 μm. By ensuring the leak repair fluid R in the mixture has a particle size exceeding 500 μm, suspension of the leak repair fluid R within the object T can be more reliably suppressed, allowing for efficient supply of the mixture to the object T. Therefore, the leak repair kit 1 of this embodiment can efficiently supply a mixture of leak repair fluid R and compressed air A.

[0023] A portion of the mixture may, for example, be an aerosol of leak repair fluid R and compressed air A. The mixing chamber 8 may also aerosolize a portion of the mixture. The aerosolized mixture is preferably less than 10% of the total mixture. In this case, the mixture can supply a portion of the leak repair fluid R as aerosol particles with a particle size of approximately 1 to 100 μm, suspended within the object. Therefore, the leak repair kit 1 of this embodiment can be used even when sound-absorbing material Ta (…) is disposed inside the object T. Figure 3 As shown in the figure, sensors and other devices with uneven structures on their inner surfaces can also partially repair leaks through a suspended mixture.

[0024] The mixing device 4 preferably has an outlet 11 for discharging the mixture of leak repair fluid R and compressed air A from the mixing chamber 8. Such a mixing device 4 can smoothly allow the leak repair fluid R and compressed air A to flow in and out, which helps to shorten the time required for leak repair.

[0025] The first inlet 9 and outlet 11 are provided, for example, on the cover member 7. In this embodiment, the first inlet 9 and outlet 11 are provided on the bottom surface 8b. The second inlet 10 is provided, for example, on the partition wall 6a of the adapter member 6. In this embodiment, the second inlet 10 is provided on the top surface 8a.

[0026] Such a mixing device 4 discharges a mixture of leak repair fluid R and compressed air A dripping from the second inlet 10 located above from the lower outlet 11, thus suppressing the retention of the dripping leak repair fluid R and generating the mixture efficiently.

[0027] The volume V1 of the compressed air A in the mixture discharged from outlet 11 is preferably 14 to 700 times the volume V2 of the leak repair fluid R. The volume ratio V1 / V2 of compressed air A to leak repair fluid R can be adjusted, for example, by changing the opening area ratio of the first inlet 9 to the second inlet 10, the pressure of the compressed air A, the viscosity of the leak repair fluid R, etc.

[0028] Here, the volume V1 of compressed air A is calculated based on the amount of air discharged from compressed air source 3 under no-load conditions per unit time. Additionally, the volume V2 of leak repair fluid R is calculated based on the weight of leak repair fluid R supplied per unit time and the specific gravity of leak repair fluid R.

[0029] By using a volume ratio of compressed air A to leak repair fluid R of more than 14 times V1 / V2, it is possible to discharge the fluid over a wide angle inside the object T. Even if the object T has an uneven internal structure, the unaerosolized mixture can be discharged over a large area around the uneven structure.

[0030] By maintaining a volume ratio (V1 / V2) of compressed air A to leak repair fluid R of 700 times or less, insufficient supply of leak repair fluid R is suppressed, enabling efficient leak repair. Furthermore, compared to supplying leak repair fluid R after it has been aerosolized, this mixing device 4 can supply a large quantity of leak repair fluid R in a short time. Therefore, the mixing device 4 of this embodiment can generate a mixture suitable for efficient leak repair even when the inner surface of the object T has an uneven structure.

[0031] Figure 3 yes Figure 1 A cross-sectional view along line AA. (e.g.) Figure 3 As shown, as a more preferred embodiment, the object T, such as a leaking tire, has, for example, a sound-absorbing material Ta disposed inside, and has an uneven structure on its inner surface. The leak repair kit 1 of this embodiment is suitable for repairing leaks in objects T, such as tires, that have an uneven structure on their inner surface.

[0032] like Figure 1 As shown, the leak repair kit 1 of this embodiment includes a first connector 12 connecting the compressed air source 3 to the first inlet 9 of the mixing device 4, and a second connector 13 connecting the outlet 11 of the mixing device 4 to the valve Tb of the leaking object T. Such a leak repair kit 1 is easy to connect and can shorten the preparation time required for leak repair.

[0033] Furthermore, although not illustrated, the leak repair kit 1 can, for example, integrate the compressed air source 3 with the mixing device 4. In this case, the first connector 12 is, for example, a connecting pipe that connects the compressed air source 3 and the mixing device 4. Such a leak repair kit 1 can eliminate the time required to connect the first connector 12, thus further reducing the preparation time required for leak repair.

[0034] The leak repair fluid R preferably contains at least a rubber solid and water. Examples of the rubber solid include natural rubber. Such a leak repair fluid R allows the rubber solid to be efficiently moved to the leaking part inside the object T, such as a leaking tire, through the pre-rotation process S4 described later, thereby shortening the time required for leak repair.

[0035] Leak repair fluid R may also contain ethylene glycol, for example. Examples of ethylene glycol include ethylene glycol, 1,3-propanediol, and propylene glycol. Such leak repair fluid R is suitable for efficiently repairing leaks when injected into objects such as leaking tires or other objects.

[0036] like Figure 3As shown, the radial angle θ for discharging the mixture of leak repair fluid R and compressed air A from the valve Tb of the leaking object T into the object T is preferably 20° or more. Here, the radial angle θ for discharging the mixture of leak repair fluid R and compressed air A is the maximum radial angle of the unaerosolized mixture discharged from the valve Tb into the object T, and is determined based on the diffusion of the leak repair fluid R within the mixture.

[0037] By ensuring that the radiation angle θ of the mixture is 20° or more, even when the inner surface of the object T has an uneven structure, the leak repair fluid R can be discharged around the uneven structure. Through the pre-rotation process S4 described later, the leak repair fluid R can be efficiently moved to the leaking part. Therefore, the leak repair kit 1 of this embodiment can efficiently repair leaks even when the inner surface of the object T has an uneven structure.

[0038] The radial angle θ of the mixture of leak repair fluid R and compressed air A discharged from the valve Tb of the object T, such as a leaking tire, into the interior of the object T is preferably 75° or less. When the leaking object T is a general tire, a radial angle θ of 75° or less for the mixture can suppress the diffusion of the leak repair fluid R to the inner sidewall, thus efficiently discharging the leak repair fluid R.

[0039] like Figure 2 As shown, the mixing chamber 8 may also have a protrusion 14 protruding from the top surface 8a toward the interior of the mixing chamber 8. For example, a conical shape with the most prominent apex is preferably used as the protrusion 14. Such a protrusion 14 enables the flow inside the mixing chamber 8 to be directional, and can efficiently discharge the mixture of leak repair fluid R and compressed air A.

[0040] The mixing chamber 8 may also have a plurality of hemispherical recesses 15 formed on at least one of the top surface 8a, bottom surface 8b, and side surface 8c. Such a plurality of recesses 15 helps to facilitate smooth flow and shorten the residence time of the mixture in the mixing chamber 8.

[0041] The adapter component 6 has a breaking portion 16 that breaks the membrane (not shown) of the opening 5a when the adapter component 6 is installed in the opening 5a of the container 5. When the mixing device 4 is installed in the container 5, such a breaking portion 16 can break the membrane of the opening 5a, allowing the leak repair fluid R to be supplied to the mixing chamber 8.

[0042] For example, if the cap component 7 is installed in an extremely low temperature environment where it is difficult to generate a mixture in the mixing device 4, it can be directly installed on the opening 5a of the container 5. In this case, the cap component 7 preferably has a secondary breaking part 17 that breaks the membrane of the opening 5a when the cap component 7 is installed on the opening 5a of the container 5. The secondary breaking part 17 is provided, for example, near the opening of the outlet 11.

[0043] Such a secondary breaking section 17 can break the membrane at the opening 5a when the cover component 7 is directly installed on the container 5. In addition, when the cover component 7 is installed on the adapter component 6 as a mixing device 4, the secondary breaking section 17 helps to reduce the flow resistance in the mixing chamber 8.

[0044] The adapter component 6 is threaded onto both the opening 5a of the container 5 and the cap component 7. The adapter component 6 is preferably sealed to the opening 5a by a sealing component 18. The adapter component 6 is also sealed to the cap component 7 by a secondary sealing component 19. This adapter component 6 is easy to install onto the container 5 and easy to install onto the cap component 7, and provides excellent airtightness after installation.

[0045] Next, refer to Figures 1 to 3 The method for repairing a leak using the leak repair kit 1 of this embodiment will be described.

[0046] Figure 4 This is a flowchart of the leak repair method according to this embodiment. Figure 4 As shown, the air leak repair method of this embodiment includes a preparation step S1 of preparing a leaking object T, such as a tire, and an air leak repair kit 1. Preparation step S1 connects, for example, a compressed air source 3 to a first inlet 9 via a first connector 12. Alternatively, preparation step S1 preferably connects an outlet 11 to the valve Tb of the leaking object T via a second connector 13.

[0047] Preparation step S1 includes, for example, installing the mixing device 4 and the opening 5a of the container 5, with the opening 5a of the container 5 facing downwards. Preferably, preparation step S1 involves connecting the flexible cord 3a of the compressed air source 3 to an external power source. In this preparation step S1, the connections are easy to understand, allowing even unfamiliar users to complete the preparation quickly.

[0048] The leak repair method of this embodiment includes a mixing step S2 in which compressed air A supplied from the first inlet 9 and leak repair fluid R supplied from the second inlet 10 are mixed in a mixing chamber 8. The mixing step S2 supplies compressed air A to the mixing chamber 8, for example, by turning on the power supply to the compressed air source 3. Preferably, the mixing step S2 uses the pulsation of the compressed air A supplied from the compressed air source 3 to repeatedly bring the mixing chamber 8 to a positive pressure state and a negative pressure state, thereby generating a mixture of leak repair fluid R and compressed air A by dripping the leak repair fluid R from the second inlet 10 into the mixing chamber 8.

[0049] The mixing process S2 is preferably carried out in such a way that the volume V1 of the compressed air A is 14 to 700 times the volume V2 of the leak repair fluid R. This mixing process S2 can generate a mixture suitable for efficiently draining the leak repair fluid R from the inside of an object T such as a leaking tire, which helps to shorten the time required for leak repair.

[0050] The mixing method for mixing leak repair fluid R and compressed air A according to this embodiment includes the mixing step S2. Therefore, the mixing method for mixing leak repair fluid R and compressed air A according to this embodiment can generate a mixture suitable for efficiently discharging leak repair fluid R into the interior of an object T such as a leaking tire, which helps to shorten the time required for leak repair.

[0051] The leak repair method of this embodiment includes a discharge step S3 in which the mixture generated in the mixing step S2 is discharged into the interior of the leaking object T, such as a tire. In the discharge step S3, it is preferable to discharge the unaerosolized mixture from the valve stem Tb of the object T into the interior of the object T at a radial angle θ of 20° or more. It is also preferable to discharge in the discharge step S3 at a radial angle θ of 75° or less. This discharge step S3 allows for efficient leak repair even when the inner surface of the object T has an uneven structure.

[0052] The leak repair method preferably includes a pre-rotation step S4 to move the leak repair fluid R discharged into the interior of the object T to the leaking part. Such a pre-rotation step S4 enables the leak repair fluid R to move quickly to the leaking part, which helps to carry out leak repairs efficiently.

[0053] Figure 5 This is a schematic diagram conceptually representing a method for determining the radiation angle θ of a mixture. For example... Figure 5 As shown, the radiation angle θ of the mixture is determined, for example, by photographing particles of leak repair fluid R discharged from the valve Tb of a cylindrical transparent acrylic pressure vessel P with an inner diameter φ of 230 mm.

[0054] The following is an example of a method for determining the radiation angle θ of a specific mixture.

[0055] exist Figure 5 In the example, the pressure vessel P has a reference plane B, corresponding to the inner cavity surface of the tire, located at a position through its central axis Pc. The valve Tb is mounted, for example, at a mounting position Pm on the cylindrical wall of the pressure vessel P, above the reference plane B, at an angle α of 45° relative to the reference plane B in a direction orthogonal to the central axis Pc. Such a pressure vessel P is suitable for reproducing the internal state of the object T during leak repair.

[0056] The internal volume of the pressure vessel P is preferably equal to the internal volume of the object T. The method for determining the radiation angle θ of such a mixture can accurately reproduce the pressure rise during leak repairs of the object T.

[0057] The preferred method for measuring the radiation angle θ of the mixture is to take images from the direction of the central axis Pc of the pressure vessel P. For example, when the vessel 5 contains 400 ml of leak repair fluid R, images are taken every 0.5 seconds for a 15-second discharge period from the start of discharge, spanning 5 to 20 seconds. The radiation angle θ of the mixture is measured by overlaying these multiple images, for example, 31 images. This method excludes leak repair fluid R dripping downwards from the valve Tb after the start of discharge and during the latter half of the discharge, ensuring an accurate measurement of the radiation angle θ.

[0058] Furthermore, the measurement time is not limited to 5–20 seconds from the start of discharge. As long as the leak repair fluid R dripping downwards from the valve Tb after the start of discharge and during the latter half of discharge can be measured to ensure a stable discharge state, any time can be used. For example, if the capacity of container 5 is small, a measurement time shorter than the aforementioned 15 seconds can be used as the discharge time shortens.

[0059] The preferred method for determining the radiation angle θ of the mixture is based on particle measurement of the leak repair fluid R located in a measurement area Z, which is part of the captured image. The measurement area Z is, for example, defined as a rectangle with a height H of 40 mm. In this embodiment, the distance L between the measurement area Z and the installation position Pm is also 40 mm. This method for determining the radiation angle θ of the mixture excludes aerosolized mixtures and leak repair fluid R rebounding on the reference plane B, and can accurately measure the radiation angle θ of the mixture.

[0060] The above describes in detail the particularly preferred embodiments of the present invention, but the present invention is not limited to the above embodiments and can be implemented in various ways.
