DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] FIG. 1 is a three-dimensional view of an on-vehicle air compressor and a tire sealant bottle according to an embodiment of the present invention. FIG. 2 is an exploded view of the on-vehicle air compressor and the tire sealant bottle of FIG. 1. FIG. 3 is a three-dimensional view of the on-vehicle air compressor of FIG. 1 connected to a tire. Referring to FIGS. 1 to 3, an on-vehicle air compressor 100 according to this embodiment includes an air compressor body 110, a bottle cap assembly 120, and a connection pipe 130. The bottle cap assembly 120 includes a bottle cap member 122 and a sealing member 124. The bottle cap member 122 is attached to the air compressor body 110 and has an air inlet end 1221 and an air outlet end 1222 connected to each other, and the air inlet end 1221 and the air outlet end 1222 are, for example, columnar bodies protruding outward from the outer surface of the bottle cap member 122, and the air inlet end 1221 and the air outlet end 1222 are, for example, parallel to each other in the air inlet end and the air outlet end. The air inlet end 1221 is suitable for being inserted into the air outlet pipe 112 of the air compressor body 110 along an insertion direction D1 (shown in FIG. 2). A sealing member 124, for example made of rubber, silicone or other kinds of elastic sealing materials, is disposed on the bottle cap member 122. The tire sealant containing bottle 50 is used for joining to the bottle cap member 122 along a joining direction D4 (shown in FIG. 2). The bottle cap member 122 may be connected to the tire 60 via a connecting pipe 130.

[0021] The high-pressure airflow from the air compressor body 110 is suitable to enter the bottle cap member 122 through the air inlet end 1221 of the bottle cap member 122, pass through the bottle cap member 122 and reach the tire sealant-containing bottle 50, and the tire sealant in the tire sealant-containing bottle 50 can pass through the bottle cap member 122, leave the bottle cap member 122 through the air outlet end 1222 of the bottle cap member 122, and flow into the tire 60 through the connecting pipe 130, thereby achieving the effect of repair and inflation. The method and principle of the air compressor body 110 generating the high-pressure airflow are well known in the art, and will not be described in detail here.

[0022] The air compressor body 110 in this embodiment further includes at least one fastening member 150 (two are shown). The fastening member 150 fastens the bottle cap member 122 to the air compressor body 110 along a fastening direction D2 (shown in FIG. 2), which is the same as the insertion direction D1.

[0023] As described above, in the present embodiment, the vehicle-mounted air compressor 100 fastens the bottle cap member 122 to the air compressor body 110 using the fastening member 150. A user can easily attach the bottle cap member 122 to the air compressor body 110 and complete the installation of the bottle cap member 122 by simply fastening the fastening member 150. Furthermore, a user can easily remove the fastening member 150 and complete the removal of the bottle cap member 122 and / or the replacement of the tire sealant storage bottle 50 by simply removing the bottle cap member 122. Furthermore, in this embodiment, the fastening direction D2 of the fastening member 150 is the same as the insertion direction D1 of the air inlet end 1221 of the bottle cap member 122, and the fastening position of the fastening member 150 and the insertion position of the air inlet end 1221 of the bottle cap member 122 are both on the same side of the air compressor body 110 (i.e., the upper side of the air compressor body 110), so that the user can sequentially insert the bottle cap member 122 and fasten the fastening member 150 at the same position and in a convenient and consistent working direction. In addition, since the fastening direction of the fastening member 150 is the same as the insertion direction of the air inlet end 1221 of the bottle cap member 122, the air inlet end 1221 can be firmly inserted into the air compressor body 110 by fastening the fastening member 150.

[0024] 4 is a three-dimensional view of the bottle cap assembly of FIG. 1. Referring to FIG. 2 and FIG. 4, in detail, the bottle cap member 122 in this embodiment has two convex ears E and two assembly holes H1 located at the two convex ears E, respectively. The two fastening members 150 are, for example, screws, which penetrate the two assembly holes H1, respectively, and are engaged with the air compressor body 110. In addition, the two assembly holes H1 are arranged along an arrangement direction D3 (shown in FIG. 2) perpendicular to the fastening direction D2 and the joining direction D4, and are respectively located on two opposite sides of the bottle cap member 122, so that the fastening members 150 can firmly fasten the bottle cap member 122.

[0025] 2, in this embodiment, the air compressor body 110 has an accommodating recess 1101 and two locking holes H2. The accommodating recess 1101 has an inner wall 1101a perpendicular to the fastening direction D2, and the locking hole H2 is located on the inner wall 1101a and is located in the accommodating recess 1101. The bottle cap member 122 is accommodated in the accommodating recess 1101, and the two fastening members 150 passing through the two assembly holes H1 are respectively locked to the two locking holes H2. Furthermore, the accommodating recess 1101 has an opening end 1101b, and a locking tool (such as a screwdriver) is suitable for extending through the opening end 1101b to the locking hole H2 and locking the fastening member 150 to the locking hole H2.

[0026] Fig. 5 is a partial three-dimensional view of the vehicle-mounted air compressor of Fig. 1. Fig. 6 is a partial cross-sectional view of the vehicle-mounted air compressor and the tire sealant bottle of Fig. 1. Referring to Figs. 5 and 6, the sealing member 124 in this embodiment is disposed in the bottle cap member 122 and surrounds the air inlet 122a. When the bottle mouth 52 of the tire sealant-containing bottle 50 is joined to the bottle cap member 122, the bottle mouth 52 of the tire sealant-containing bottle 50 presses down the sealing member 124, compressing the sealing member 124 between the bottle cap member 122 and the bottle mouth 52 of the tire sealant-containing bottle 50, thereby preventing the tire sealant in the tire sealant-containing bottle 50 from leaking out from the gap between the bottle mouth 52 and the bottle cap member 122.

[0027] Fig. 7 is a partial structure of the vehicle-mounted air compressor and tire sealant storage bottle of Fig. 1. Fig. 8 is a partial structure of the vehicle-mounted air compressor and tire sealant storage bottle of Fig. 1. Referring to Fig. 7 and Fig. 8, specifically, the high-pressure airflow from the air compressor body 110 (shown in Fig. 1) can pass through the air inlet end 1221 and the air inlet 122a in order along the flow path P1 shown in Fig. 7 to reach the inside of the tire sealant storage bottle 50, and the tire sealant inside the tire sealant storage bottle 50 can follow the high-pressure airflow and pass through the air outlet 122b and the air outlet end 1222 in order along the flow path P2 shown in Fig. 8 to flow to the tire 60 (shown in Fig. 3) via the connecting pipe 130.

[0028] 4, in this embodiment, the bottle cap member 122 has two blade-tip convex ribs 1224. In the process of joining the tire sealant-containing bottle 50 and the bottle cap member 122, the blade-tip convex ribs 1224 are suitable for cutting the sealing film on the bottle mouth 52 of the tire sealant-containing bottle 50 so that the bottle cap member 122 can smoothly pass through the internal space of the tire sealant-containing bottle 50.

[0029] The operation process of the vehicle air compressor according to this embodiment will be described below.

[0030] 9A to 9E are operation flowcharts of the vehicle-mounted air compressor of FIG. 1. FIGS. 10A to 10C are top views of the vehicle-mounted air compressor of FIGS. 9A to 9C, respectively. First, as shown in FIGS. 9A and 10A, the connecting pipe 130 is attached to the air outlet end 1222 of the bottle cap member 122, and the connecting pipe 130 is fastened to the air outlet end 1222 using a tube clamp 160. Next, as shown in FIGS. 9B and 10B, the bottle cap member 122 is attached to the air compressor body 110 by the guide of the two guide surfaces 116 of the air compressor body 110, and at the same time, the air inlet end 1221 of the bottle cap member 122 is inserted into the air outlet pipe 112 of the air compressor body 110 to connect the air outlet pipe 112 to the air inlet 122a. The gap between the air inlet end 1221 and the air outlet tube 112 can be sealed by a sealing ring 170 attached to the air inlet end 1221. In addition, the upper surface of the air compressor body 110 has an opening 110a, and the location where the air outlet tube 112 and the bottle cap member 122 are connected to each other corresponds to the opening 110a as shown in Fig. 10B, which makes it convenient for the user to visually check whether the air outlet tube 112 and the bottle cap member 122 are securely connected through the opening 110a.

[0031] 9C and 10C, the bottle cap member 122 is fastened to the air compressor body 110 by the fastening member 150 to produce the state shown in FIG. 9D. Next, as shown in FIG. 9D to FIG. 9E, the bottle mouth 52 of the tire sealant storage bottle 50 is joined to the bottle cap member 122. In this process, the sealing film 52a at the bottle mouth 52 is cut by the blade-tip convex rib 1224 (shown in FIG. 4) of the bottle cap member 122, so that the high-pressure airflow from the air compressor body 110 can enter the tire sealant storage bottle 50 along the flow path P1 in the subsequent repair and expansion work, and the tire sealant 501 in the tire sealant storage bottle 50 can leave the tire sealant storage bottle 50 along the flow path P2 accompanied by the high-pressure airflow in the subsequent repair and expansion work. Finally, as shown in FIG. 3, once the connecting tube 130 is connected to the tire 60, the vehicle air compressor 100 can begin repairing and inflating the tire 60.

[0032] FIG. 11 shows the tire sealant bottle of FIG. 1 replaced with a cover. FIG. 12 shows the tire sealant bottle of FIG. 2 replaced with a cover. FIG. 13A shows the tire sealant bottle of FIG. 9D replaced with a cover. FIG. 13B shows the tire sealant bottle of FIG. 9E replaced with a cover. The vehicle-mounted air compressor 100 in this embodiment may only inflate the tire 60 without repairing the tire 60. Specifically, the tire sealant bottle 50 of FIG. 1, FIG. 2, FIG. 9D, and FIG. 9E can be replaced with the cover 70 of FIG. 11, FIG. 12, FIG. 13A, and FIG. 13B, and the remaining operation procedures are the same as those described above and will not be described in detail here. In the method shown in Figures 11, 12, 13A, and 13B, tire sealant containing bottle 50 is not used, so the high-pressure airflow from air compressor main body 110 passes through bottle cap assembly 120 as shown by flow path P3 in Figure 13B, and then reaches and inflates the tire directly.

[0033] Hereinafter, a vehicle-mounted air compressor 100' according to another embodiment of the present invention will be described. The main difference from the above embodiment is that the air inlet direction and the air outlet direction of the bottle cap member 120' of the vehicle-mounted air compressor 100' are perpendicular to each other, and the other parts are the same as the above embodiment. A detailed description will be given below. Note that the same or similar components as those of the above embodiment are denoted by the same or similar symbols.

Referring to Figs. 21 and 22, specifically, the high-pressure air flow from the air compressor main body 110' (shown in Fig. 1) can pass through the air inlet end 1221' and the air inlet 122a' in order along the flow path P1' shown in Fig. 21 to reach the inside of the tire sealant storage bottle 50, and the tire sealant inside the tire sealant storage bottle 50 can follow the high-pressure air flow and pass through the air outlet port 122b' and the air outlet end 1222' in order along the flow path P2' shown in Fig. 22, and flow to the tire 60 (shown in Fig. 3) via the connecting pipe 130.

[0042] 18, in this embodiment, the bottle cap member 122' has two blade-tip convex ribs 1224'. In the process of joining the tire sealant bottle 50 and the bottle cap member 122', the blade-tip convex ribs 1224' are suitable for cutting the sealing film on the bottle mouth 52 of the tire sealant bottle 50 so that the bottle cap member 122' can smoothly pass through the internal space of the tire sealant bottle 50.

[0043] The operation process of the vehicle air compressor according to this embodiment will be described below.

[0044] Fig. 23A to Fig. 23E are operation flowcharts of the vehicle-mounted air compressor of Fig. 14. Fig. 24A to Fig. 24C are top views of the vehicle-mounted air compressor of Fig. 23A to Fig. 23C, respectively. First, the connecting pipe 130 (shown in Fig. 15) is attached to the bottle cap member 122', and then, as shown in Fig. 23A (Fig. 24A) to Fig. 23B (Fig. 24B), the bottle cap member 122' is attached to the air compressor body 110' by the guide of the two guide surfaces 116' of the air compressor body 110', and at the same time, the air inlet end 1221' of the bottle cap member 122' is inserted into the air outlet pipe 112' of the air compressor body 110' to connect the air outlet pipe 112' to the air inlet 122a'. The gap between the air inlet end 1221' and the air outlet tube 112' can be sealed by a sealing ring 170 provided at the air inlet end 1221'. In addition, the upper surface of the air compressor body 110' has an opening 110a', and the part where the air outlet tube 112' and the bottle cap member 122' are connected to each other corresponds to the opening 110a' as shown in Fig. 24B, so that it is convenient for the user to visually check whether the air outlet tube 112' and the bottle cap member 122' are securely connected through the opening 110a'.

[0045] Next, as shown in Fig. 23C and Fig. 24C, the bottle cap member 122' is fastened to the air compressor body 110' by the fastening member 150 to produce the state shown in Fig. 23D. Next, as shown in Fig. 23D to Fig. 23E, the bottle mouth 52 of the tire sealant storage bottle 50 is joined to the bottle cap member 122'. In this process, the sealing film 52a at the bottle mouth 52 is cut by the blade-tip convex rib 1224' (shown in Fig. 18) of the bottle cap member 122', and the high-pressure airflow from the air compressor body 110' can enter the tire sealant storage bottle 50 along the flow path P1' in the subsequent repair and expansion work, and the tire sealant 501 in the tire sealant storage bottle 50 can leave the tire sealant storage bottle 50 along the flow path P2' along with the high-pressure airflow in the subsequent repair and expansion work. Finally, as shown in FIG. 16, once the connecting tube 130 is connected to the tire 60, the vehicle mounted air compressor 100' can begin repairing and inflating the tire 60.

[0046] FIG. 25 shows the tire sealant bottle of FIG. 14 replaced with a cover. FIG. 26 shows the tire sealant bottle of FIG. 15 replaced with a cover. FIG. 27A shows the tire sealant bottle of FIG. 23D replaced with a cover. FIG. 27B shows the tire sealant bottle of FIG. 23E replaced with a cover. In addition, the vehicle-mounted air compressor 100' in this embodiment may only inflate the tire 60 without repairing the tire 60. Specifically, the tire sealant bottle 50 of FIG. 14, FIG. 15, FIG. 23D, and FIG. 23E may be replaced with the cover 70 of FIG. 25, FIG. 26, FIG. 27A, and FIG. 27B, and the remaining operation procedures are the same as those described above, so they will not be described in detail here. In the method shown in Figures 25, 26, 27A, and 27B, the tire sealant containing bottle 50 is not used, so the high-pressure air flow from the air compressor main body 110' passes through the bottle cap assembly 120' as shown by the flow path P3' in Figure 27B, and then reaches the tire directly to inflate it.

[0047] In summary, the vehicle-mounted air compressor of the present invention uses a fastening member to fix the bottle cap member to the air compressor body, and the user can simply attach the bottle cap member to the air compressor body and complete the installation of the bottle cap member by simply fastening the fastening member, and the user can complete the removal of the bottle cap member and / or replacement of the tire sealant bottle by simply removing the fastening member and then removing the bottle cap member. Furthermore, the present invention makes the fastening direction of the fastening member the same as the insertion direction of the air inlet end of the bottle cap member, so that the user can insert the bottle cap member and fasten the fastening member in order in a convenient and consistent working direction. In addition, since the fastening direction of the fastening member is the same as the insertion direction of the air inlet end of the bottle cap member, the air inlet end can be firmly inserted into the air compressor body by fastening the fastening member. [Industrial Applicability]

[0048] The present invention provides an on-board air compressor and its bottle cap assembly, which can be applied to vehicle inflation and / or repair equipment. [Explanation of symbols]
