[0036] The gas-liquid switch assembly of the present embodiment includes a gas-liquid switching operating component and a switch body component that cooperates with the switch body to form a gas passage and a liquid passage, respectively. When the gas-liquid switching operating component and the switch body cooperate to form the gas passage, the gas state is inflated. When the gas-liquid switching operating component and the switch body cooperate to form the liquid passage, the tire repair state is inflated. The gas-liquid switching operating component can be linearly displaced to switch between the inflation state and the tire repair state. This gas-liquid switch assembly has the advantages of preventing misoperation, a simple structure, and easy processing and assembly.

[0037] In order to better understand the above technical solution, Figure 1-16 The present invention will be further described in the following and specific embodiments, wherein like reference numerals represent like parts unless otherwise specified. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application. The background section of the present invention may contain background information about the problem or environment of the present invention, but does not necessarily describe the prior art. Therefore, the content included in the background section is not an admission by the applicant of the prior art.

[0038] Example 1

[0039] The gas-liquid transfer switch assembly of this embodiment is as follows: Figure 1-8 As shown, it includes a gas-liquid conversion operating component 10 and a conversion switch body component 20 that cooperates with the gas-liquid conversion operating component 10 to form a gas passage and a liquid passage respectively, and a sealing component 30 that seals the gas passage and the liquid passage.

[0040] The gas-liquid conversion operating component 10 is as follows Figure 1As shown, the tire includes an operating portion 13 and a first conduit 11 and a second conduit 12 located below the operating portion 13. The first conduit 11 and the second conduit 12 are arranged side by side. A first snap-fit ​​structure 14 is preferably provided below the operating portion for determining the inflation state. Two first snap-fit ​​structures 14 are provided, one on each side below the operating portion 13. These two first snap-fit ​​structures 14 can be used to determine the preset inflation state. A second snap-fit ​​structure 15 is further preferably provided below the operating portion 13 for determining the tire repair state.

[0041] The transfer switch body component 20 is as follows Figure 2 、 Figure 7 As shown, it includes a connecting portion 23 for connecting to a tire sealant bottle, a first pipe joint 21 and a second pipe joint 22 arranged opposite each other at a predetermined distance, an air outlet 24, and a liquid suction tube 25. The air outlet 24 and the liquid suction tube 25 are respectively provided on the bottom wall 231 of the connecting portion 23 and both form passages with the first pipe joint 21 and the second pipe joint 22. The first pipe joint 21 and the second pipe joint 22 are distributed on both sides of the connecting portion 23. The connecting portion 23 has internal or external threads and can be detachably connected to the tire sealant bottle through a threaded connection.

[0042] The connecting portion 23 can be configured as a trough-like structure, comprising a first sidewall 201, a second sidewall 202, a third sidewall 203, a fourth sidewall 204, and a bottom wall 205. The first sidewall 201, the second sidewall 202, the third sidewall 203, and the fourth sidewall 204 are all perpendicularly disposed on the four sides of the bottom wall 205 and connected end to end. The first pipe joint 21 is disposed on the first sidewall 201 and forms a passageway through a through-hole provided in the first sidewall 201. The second pipe joint 22 is disposed on the second sidewall 202 and forms a passageway through a through-hole provided in the second sidewall 202. The connecting portion 23 is fixedly mounted on the third sidewall 203. The air outlet 24 and the liquid suction pipe 25 are disposed on the third sidewall 203 and located within the connecting portion 23. The liquid suction pipe 25 has a predetermined length and outer diameter to facilitate installation of a liquid discharge hose. A preferred structural arrangement is that there are two second snap-fit ​​structures 15, which are arranged side by side at the bottom of the first pipe 11, and correspondingly, the bottom wall 205 is provided with a snap-fit ​​hole 2051 that matches and corresponds to the position of the second snap-fit ​​structure 15. The two second snap-fit ​​structures 15 are preferably arranged in opposite directions, that is, the hooks 151 of the two second snap-fit ​​structures 15 are in opposite directions. This arrangement makes the force directions when snapping into the snap-fit ​​holes 2051 opposite, so that the force of each part is more uniform and the positioning after snapping is more secure. However, it is not limited to this. For example, if the two second snap-fit ​​structures 15 are arranged in the same direction or at a certain angle (between the same and opposite), the corresponding opening position and angle of the snap-fit ​​holes 2051 can be matched, and the purpose of the invention of this application can also be achieved. The fourth side wall 204 is set to a structural shape with a structural reinforcement effect, for example, the fourth side wall 204 is set to a curved cross-section or reinforcing ribs are added at appropriate locations. The fourth sidewall 204 is also preferably provided with two guide grooves 2041, whose positions correspond to the two first snap structures 14, respectively. These grooves are used to guide the two first snap structures 14 when the gas-liquid conversion operating component 10 makes linear displacement, thereby making operation more convenient and smooth. Furthermore, in other specific embodiments, an anti-detachment member 2011 may be provided on the first sidewall 201 to prevent the air pipe connected to the first pipe joint 21 from falling off.

[0043] The sealing member 30 is as follows Figure 3As shown, it is preferred to use an integrated sealing component, including a first through hole 31 and a second through hole 32 provided at both ends, and a fixing hole 33 provided in the middle. The fixing hole 33 can be set to have a set of opposite sides of the cross section parallel, and the other set of opposite sides are arc-shaped and convex toward each other. This shape of the structure can maximize the size of the fixing hole 33, enhance the fixing effect, and balance the structural strength of each part of the integrated sealing component 30, so that the sealing effect is more reliable and more durable. Obviously, the interface shape of the fixing hole 33 is not limited to this, and can be appropriately deformed. Figure 1 and Figure 7 As shown, a first extension wall 16 and a second extension wall 17 are provided on either side below the operating portion 13 for securing the first pipeline 11 and the second pipeline 12, respectively. A first groove 161 for mounting the sealing component 30 is provided on the outer side of the first extension wall 16, and a second groove 171 for mounting the sealing component 30 is provided on the outer side of the second extension wall 17. Both the first groove 161 and the second groove 171 are provided with fixing posts 18 that match the fixing holes. When the sealing component 30 is positioned within the first groove 161 and the second groove 171, the fixing posts 18 snap into the fixing holes, thereby assisting in positioning the sealing component 30. The combined positioning effect of the fixing posts 18 and the inner circumferential wall of the fixing hole 33 enhances the positioning effect and prevents damage to the sealing component 30 caused by excessive deformation during movement.

[0044] In other embodiments, Figure 2 As shown, the fourth side wall 204 is further provided with a crossbeam 2042, the two ends of which are respectively connected to the first side wall 201 and the second side wall 202, and the portion corresponding to the guide groove 2041 can be respectively inserted into the narrow groove 19 between the first snap structure 14 and the first extension wall 16, and the first snap structure 14 and the second extension wall 17, and the fixing effect is achieved by friction, as shown in FIG. Figure 1 Preferably, the crossbeam 2042 is entirely plate-shaped, and has a thickened snap-fit ​​portion 2043 on its outer side. The snap-fit ​​portion 2043 smoothly transitions with the rest of the crossbeam 2042. A recess 141 that matches the outer contour of the snap-fit ​​portion 2043 is provided near the end of the first snap structure 14. The engagement between the snap-fit ​​portion 2043 and the recess 141 allows for more reliable fixation of the relative positions of the gas-liquid conversion operating component 10 and the transfer switch body 20.

[0045] In addition, those skilled in the art understand that the fixing hole 33 may also be replaced by a fixing slot (or blind hole) structure, and the corresponding fixing effect may be achieved.

[0046] like Figure 4-8 As shown, when both ends of the first pipe 11 are connected to the first pipe joint 21 and the second pipe joint 22 through the sealing component 30, they are in the inflated state. Figure 4 As shown, the two snap-fitting portions 2043 are respectively snapped into the two recesses 141 of the first snap-fit ​​structures 14, thereby achieving relative fixation of the gas-liquid conversion operating component 10 and the conversion switch body component 20. Figure 5 As shown, air from an air source (such as an inflator or a high-pressure gas tank, etc.) can enter the first pipe 11 through the first pipe joint 21, and then be directly or indirectly output to the tire or other inflated object through the second pipe joint 22. When the gas-liquid conversion operating component 10 is pressed down and moved to the position where the two ends of the second pipe 12 are connected to the first pipe joint 21 and the second pipe joint 22 through the sealing component 30, the tire is in the repair state. At this time, as shown in FIG. Figure 6-9 As shown, the two second buckle structures 15 are respectively inserted into the two clamping holes 2051, thereby achieving relative fixation of the gas-liquid conversion operating component 10 and the conversion switch body component 20. Figure 8-9 As shown, the second pipe 12 includes a left section 121 and a right section 122. The left section 121 is connected to the first pipe joint 21 and the air outlet 24 at both ends, while the right section 122 is connected to the liquid suction pipe 25 and the second pipe joint 22 at both ends. Air from the air source can enter the tire sealant bottle connected to the connecting portion 23 through the first pipe joint 21, the left section 121 of the second pipe 12, and the air outlet 24. The sealant is then pumped into the liquid suction pipe 25, passed through the right section 122 of the second pipe 12, and into the second pipe joint 22, before being directly or indirectly delivered to the tire to be repaired. The air-to-liquid conversion operating component 10 can be linearly moved to switch between the inflation state and the tire repair state.

[0047] In this embodiment, the gas-liquid conversion operating component 10 and the transfer switch body 20 are preferably integrally molded, and can be integrally molded by methods such as injection molding. This integral molding streamlines the overall product structure, with the entire assembly consisting of only three integrated components: the gas-liquid conversion operating component 10, the transfer switch body 20, and the sealing component 30. This makes assembly extremely convenient and quick, significantly reducing the number of assembly steps and improving assembly efficiency. It also effectively avoids assembly defects and significantly reduces product assembly costs.

[0048] Example 2

[0049] A tire sealant bottle, such as Figure 10As shown, the embodiment includes a bottle body 60 and the gas-liquid switch assembly described in Example 1 above. The bottle body 60 and the gas-liquid switch assembly are connected to each other via the connecting portion 23. Specifically, the mouth of the bottle body 60 is provided with external threads that mate with the internal threads provided on the connecting portion 23. Obviously, the positions of the external and internal threads can also be interchanged to achieve the same connection. Furthermore, the threaded connection can be replaced with a snap-fit ​​connection or other connection method, as long as a reliable connection is achieved.

[0050] Example 3

[0051] A pneumatic tire repair device includes an inflator and a tire sealant bottle. The tire sealant bottle is the tire sealant bottle described in Example 2 above. The inflator includes a housing and an inflator core. The inflator core and the tire sealant bottle are disposed within the housing. A first pipe joint 21 is connected to the outlet of the inflator. This inflatable tire repair device can be easily switched between inflation and repair modes and also features a misoperation prevention feature, significantly enhancing the user experience.

[0052] like Figure 11 As shown, the tire inflation and repairing machine of this embodiment further includes a safety buckle 71 for preventing consumers from misoperating. The safety buckle 71 is slidably mounted on the housing 70 and includes an operating portion 711 and a locking portion 712. The operating portion is preferably provided with an anti-slip structure, such as a plurality of arc-shaped raised strips or a plurality of raised points. Figure 12-13 As shown, in the inflated state, the engaging portion 712 is by default engaged with the side edge of the top plane of the gas-liquid conversion operating component 10. At this time, the gas-liquid conversion operating component 10 is limited and cannot be pressed down, that is, it cannot be converted to the tire repair state. When it is necessary to perform a tire repair operation, the safety buckle 71 can be pushed outwards through the operating portion 711, so that the safety buckle 71 slides away from the side edge of the top plane of the gas-liquid conversion operating component 10. At this time, Figure 14-16 As shown, the gas-liquid conversion operating component 10 will not be limited, so it can be pressed down to convert to the tire repair state. Through the cooperation of the above simple structure, the effect of preventing misoperation can be achieved.

[0053] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0054] Those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples without mutual contradiction.

[0055] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
