Description

Sealant bottle and tire repair method Technical Field

[0001] The present application relates to the field of automobile maintenance, and in particular to a sealant bottle and a tire repair method using the sealant bottle. Background Art

[0002] During the driving process of a car, the tire may sometimes have abnormal conditions, such as flat tire, broken tire, etc. In this case, a spare tire is usually used to replace the flat tire or broken tire or to provide a quick tire repair and inflation for the tire.

[0003] There is a quick tire repair method, in which when a tire is punctured, a sealant is injected into the tire to repair the punctured portion of the tire.

[0004] Sealant is a polymeric synthetic substance that is normally liquid and stored in a sealant bottle. To perform the above tire repair method, air is first pumped into the sealant bottle, which then pumps the sealant out of the bottle and onto the tire. As the sealant enters the tire, it collides with and mixes with the surrounding air, increasing in volume and forming a foamy film. Once inside the tire, the foamed sealant reaches the puncture site and coats the tire's inner wall, forming a sealing film.

[0005] WO2022006805A1 discloses a sealant bottle that can ensure that the sealant has already formed a foam state and a considerable amount of sealant when it reaches the main inlet of the tire. It is necessary to repair the tire while it is rolling.

[0006] US20190275756A1 discloses a method and apparatus for sealing and inflating inflatable articles, wherein the sealant is pumped passively. During tire inflation, the pressure in the air duct is higher than the sealant, causing the sealant in the sealant bottle to flow out very slowly or even not flow out at all. This solution requires the use of their specially designed air compressor or special accessories. At the same time, the bottle is in direct contact with the hot air (~80°C or above) at or near the air compressor outlet nozzle, which can easily cause the glue to mutate or even solidify.

[0031] It is easy to understand that, based on the technical solution of this application, without changing the essential spirit of this application, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of this application and should not be regarded as the entire application or as a limitation or restriction of the technical solution of this application.

[0032] According to one embodiment of the present application, a sealant bottle includes: a bottle body for containing sealant, which can be made of glass or metal, for example; a gas inlet pipe, through which gas can enter the bottle body; and a gas-liquid mixer. As shown in FIG5 , the gas-liquid mixer 3 has an air inlet 31 for gas entry and a liquid inlet 32 ​​for sealant entry, with the size ratio of the air inlet to the liquid inlet being 2-27. For example, the size ratio of the air inlet to the liquid inlet is 2, 8, 8.1, 10, 25, 25.6, 26, 26.8, 27, etc. The gas-liquid mixer can mix gas and sealant into a mist mixture, and the gas-liquid mixer also has an outlet 33 for the mist mixture to exit. The sealant bottle also includes a mixture exit pipe, through which the mist mixture mixed by the gas-liquid mixer can exit the bottle body.

[0033] In this embodiment of the sealant bottle, the gas-liquid mixer and the ratio of the gas inlet to the liquid inlet of the gas-liquid mixer are set to 2-27. This allows the gas entering the bottle to mix with the sealant in the bottle to form an atomized mixture, which is then delivered to the tire to be repaired. This reduces the amount of sealant used while improving the sealing effect. For example, the amount of sealant used in a single repair process can be reduced to 5-10g.

[0034] Tire repair kits on the market in the past required that sealant be pumped into the tire first, then the vehicle was started and the tire rolled; the liquid sealant then flowed to the damage and sealed it.

[0035] Adopt sealant bottle according to this embodiment, can under the situation that does not need rolling, tire is repaired.For example, when tire is mounted on vehicle, need not start vehicle and make tire roll, especially rolling along road surface just can complete tire repair.

[0036] The sealant is pumped as an aerosol (a mist-like mixture). It flows with the compressed air and reaches the puncture site as air leaks from the puncture site. The sealant that reaches there quickly condenses and forms a sealing gel, which greatly reduces the risk of driving with a punctured tyre.

[0037] In a gas-liquid mixer, the liquid inlet may be composed of one or more sub-inlets, and the air inlet may also be composed of one or more sub-inlets. Dimensions, for example, refer to cross-sectional areas. If the liquid inlet is composed of multiple sub-inlets, the size of the liquid inlet refers to the sum of the dimensions of all sub-inlets; if the air inlet is composed of multiple sub-inlets, the size of the air inlet refers to the sum of the dimensions of all sub-inlets. The cross-sectional shapes of the liquid inlet / sub-inlet / air inlet / sub-inlet may be circular, rectangular, triangular, etc.

[0038] The gas-liquid mixer can be configured in a spherical, cubic, conical, or cylindrical shape. For example, the gas-liquid mixer is configured in a cylindrical shape, with the gas inlet consisting of multiple sub-inlets, which are symmetrically configured in the radial direction of the cylinder; and the liquid inlet consisting of a single sub-inlet, which is located at the symmetrical center of the cylindrical gas-liquid mixer.

[0039] The gas inlet, liquid inlet and outlet of the gas-liquid mixer are not limited to the arrangement shown in FIG5 , and they can be exchanged or arranged at other positions when necessary.

[0040] The sealant bottle further includes a cap for sealing the bottle. A first conduit may be provided in the cap, the first conduit being configured as part of or communicating with the gas inlet conduit to allow gas to enter the bottle. A second conduit may also be provided in the cap, the second conduit being configured as part of or communicating with the mixture outlet conduit to allow the atomized mixture to exit the bottle and subsequently be delivered to the tire to be repaired.

[0041] In the embodiment shown in FIG1 , the gas-liquid mixer 3 is disposed in a receiving space defined by a bottle body 1 and a bottle cap 5. One end of the gas-liquid mixer 3 is fixed to the bottle cap 5, for example, to the bottom of the bottle cap 5, by ultrasonic welding, thereby establishing a high-quality connection and obtaining a reliable seal between the gas-liquid mixer 3 and the bottle cap 5 in a simple, efficient, and low-cost manner; the outlet 33 of the gas-liquid mixer 3 is connected to the second pipeline 52 in the bottle cap 5; the other end of the gas-liquid mixer 3 is connected to a sealant tube 6, through which the sealant 11 contained in the bottle body 1 (as shown in the dark area in the figure) can be connected to the liquid inlet 32 ​​of the gas-liquid mixer 3. The end of the sealant tube 6 away from the gas-liquid mixer 3 (i.e., the free end) extends to the bottom of the bottle body 1.

[0042] The ratio of the inner diameter of the sealant tube 6 to the inner diameter of the liquid inlet 32 ​​is 1-5.7, for example 1, 4.4 and 5.7. The sealant tube 6 can be a capillary tube with an inner diameter greater than 0.5 mm.

[0043] In the embodiment shown in Figure 1, the exemplary working process of the sealant bottle is: the gas (for example, high-pressure gas) from the gas inlet pipe 2 flows through the first pipe 51 in the bottle cap 5 and then enters the containing space defined by the bottle body 1 and the bottle cap 5; on the one hand, the gas enters the gas-liquid mixer 3 from the air inlet 31 of the gas-liquid mixer 3, and on the other hand, the sealant (for example, in liquid state) enters the liquid inlet 32 ​​of the gas-liquid mixer 3 through the sealant pipe 6 under the action of the gas pressure; the gas and the sealant are mixed into a mist mixture in the mixing area 34 of the gas-liquid mixer 3 (as shown by the dotted line in Figure 5) and discharged through the outlet 33 of the gas-liquid mixer 3; the mist mixture discharged from the gas-liquid mixer 3 passes through the second pipe 52 in the bottle cap 5 and enters the mixture exit pipe 4, and is then transported to the tire to be repaired; after entering the damaged tire, the mist mixture with the sealant will automatically flow to the damaged part of the tire as the tire leaks and gather and solidify there, and the sealant accumulates more and more until the damaged part of the tire is completely sealed.

[0044] Table 1 shows data from several comparative tests. Tests 1-11 used the sealant bottle according to the embodiment shown in Figure 1 to repair tires; in contrast, Test 0 employed a traditional tire repair method. "Undetectable" indicates a leak rate less than 0.001 bar / min, low temperature refers to -30°C, and high temperature refers to 70°C. The comparison in Table 1 demonstrates that using the sealant bottle according to the embodiment shown in Figure 1 achieves better tire sealing with a smaller sealant dosage.

[0045] Table 1

[0046]

[0047] In the embodiment shown in FIG. 2 , a sealant tube 6 is provided in the bottle body 1. The sealant contained in the bottle body 1 can communicate with the liquid inlet 32 ​​of the gas-liquid mixer 3 through the sealant tube 6. The gas-liquid mixer 3 is disposed in the sealant tube 6. One end of the sealant tube 6 is connected to the second pipeline 52 in the bottle cap 5, and the other end of the sealant tube 6 extends to the bottom of the bottle body 1.

[0048] The gas-liquid mixer 3 can be integrally constructed with the sealant tube 6; the gas-liquid mixer 3 can also be constructed separately from the sealant tube 6. In this case, the sealant tube 6 has a hole at the gas-liquid mixer 3 so that the gas inlet 31 of the gas-liquid mixer 3 can be connected to the outside world. The sealant tube 6 can be constructed as a multi-tube, that is, the sealant tube is composed of multiple sub-tubes.

[0049] In the embodiment shown in FIG3 , a mixing tube 7 is provided in the bottle body 1. The mixing tube 7 is connected to the outlet 33 of the gas-liquid mixer 3. The gas-liquid mixer 3 is disposed at the end of the mixing tube 7 (i.e., the free end) away from the bottle cap 5. The end of the mixing tube 7 (i.e., the fixed end) away from the gas-liquid mixer 3 is connected to the second pipeline 52 in the bottle cap 5. The mixing tube 7 can be rigid or flexible.

[0050] In the embodiments shown in Figures 2 and 3, the sealant can be provided to the tire to be repaired in the form of a liquid and a mist mixture, so that the tire can be repaired with sealants in various forms to meet various application scenarios; in addition, the ratio of the sealant in the liquid state to the sealant in the mist mixture can be controlled, for example, by tilting or flipping the bottle and / or the sealant tube, and the sealant can even be provided to the tire to be repaired entirely in the form of a mist mixture, so as to achieve the best sealing effect in the best manner.

[0051] In the embodiment shown in FIG4 , similar to the embodiment in FIG3 , a mixing tube 7 is provided in the bottle body 1 , the mixing tube 7 is connected to the outlet 33 of the gas-liquid mixer 3, and the gas-liquid mixer 3 is provided at the end of the mixing tube 7 away from the bottle cap 5. The end of the mixing tube 7 away from the gas-liquid mixer 3 is connected to the second pipeline 52 in the bottle cap 5. In addition, the gas-liquid mixer 3 floats on the sealant. The density of the gas-liquid mixer 3 is less than the density of the sealant (for example, less than 1 g / cm 3 ), and the mixing pipe 7 is at least partially flexible so as not to hinder the gas-liquid mixer 3 from floating on the sealant. In this way, regardless of the angle of the bottle body 1 (assuming that the bottle body 1 is upright on the ground at 0 degrees, the bottle body 1 can be flipped to any angle, such as 90 degrees, 135 degrees, or 180 degrees), the gas-liquid mixer 3 always floats on the sealant, and gas can enter the gas-liquid mixer 3 from the gas inlet 31 without hindrance, thereby stably producing a mist mixture.

[0052] Furthermore, the structure of the gas-liquid mixer 3 is designed so that when it floats on the sealant, the liquid inlet 32 ​​is located below the sealant liquid level, and the gas inlet 31 is located above the sealant liquid level. This can be achieved, for example, by adjusting the weight distribution of the gas-liquid mixer 3. In this way, the ratio of gas to sealant in the mist mixture mixed by the gas-liquid mixer 3 is always stable.

[0053] For example, the density of the mixture tube 7 is less than the density of the sealant (for example, less than 1 g / cm 3The mixture pipe 7 is made of, for example, a lightweight material, so as not to hinder the gas-liquid mixer 3 from floating on the sealant, and may even provide additional buoyancy to help the gas-liquid mixer 3 float.

[0054] The gas-liquid mixer 3 can be made of metal, plastic, or a combination thereof. For example, in the embodiment shown in FIG3 , the gas-liquid mixer 3 can be made of metal, which is conducive to sinking to the bottom; in the embodiment shown in FIG4 , the gas-liquid mixer 3 can be made of plastic, which is conducive to floating.

[0055] According to one embodiment of the present invention, a specialized compressor or accessories are not required, and the location of the gas-liquid mixer can be changed as needed (near the bottle cap, together with the bottle cap, at the bottom, etc.). Furthermore, the bottle body is not directly exposed to the hot air at or near the outlet nozzle of the air compressor, which will not cause the glue to distort or even solidify.

[0056] The present invention also includes a tire repair method, which uses the aforementioned sealant bottle to repair the tire. The technical features and technical effects of the method correspond to the above description and will not be repeated here.

[0057] In the tire repair method, the tire is repaired without rolling. For example, when the tire is mounted on a vehicle, the tire can be repaired without starting the vehicle and rolling the tire, especially rolling it along a road surface.

[0058] An exemplary working process of the tire repair method is as follows: compressed gas generated by an air compressor enters the sealant bottle through a gas inlet pipe, the compressed gas is mixed with the sealant in the sealant bottle to form a mist mixture (possibly with a small amount of foam and liquid) and leaves the sealant bottle through the mixture exit pipe, and is then delivered to the tire to be repaired and forms a sealing gel at the damaged tire.

[0059] The technical scope of the present application is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical ideas of the present application, and these deformations and modifications should all fall within the scope of protection of the present application.
