Description

[Technical field]

[0001] The present invention relates to an air compressor, and more particularly to an air compressor for use in a vehicle. [Background technology]

[0002] The vehicle-mounted air compressor can be used together with a tire sealant bottle to repair or fill a vehicle tire with air, and can also be used without a tire sealant bottle to fill a vehicle tire with air. Generally, when repairing or filling a tire with air, a bottle cap assembly needs to be provided on the air compressor body of the vehicle-mounted air compressor to be connected to the tire sealant bottle, and the high-pressure air flow from the air compressor body needs to enter the tire sealant bottle through the bottle cap assembly, so that the tire sealant in the tire sealant bottle can enter the tire by the high-pressure air flow to achieve the effect of repairing or filling the tire with air.

[0003] If the tire sealant in the tire sealant bottle unintentionally passes through the bottle cap assembly and flows into the air compressor body, the air compressor body may not be able to operate normally. If an additional part is added to the bottle cap assembly to prevent the tire sealant from flowing into the air compressor body in order to avoid the above-mentioned situation from occurring, the number of parts and the difficulty of manufacturing and assembling the bottle cap assembly will increase. Summary of the Invention [Problem to be solved by the invention]

The flow guide portion communicates with the air inlet through the air inlet hole and communicates with the air outlet through the air outlet hole. Airflow from the air compressor body passes through the air inlet, the air inlet hole, the air outlet hole, and the air outlet in this order.

[0006] The bottle cap assembly of the present invention is applied to an on-vehicle air compressor and includes a bottle cap member and a seal and flow guide member. The bottle cap member is provided on an air compressor body of the on-vehicle air compressor and has an air inlet and an air outlet, and the bottle cap member communicates with the air compressor body through the air inlet.

[0011] In one embodiment of the present invention, the above-mentioned flow guide includes a boss, the at least one air inlet hole is located at the top end of the boss, and the bottom end of the boss is adjacent to the air exhaust hole and the seal portion.

[0012] In one embodiment of the present invention, the sealing and flow guiding member has at least one locating slot and the bottle cap member has at least one locating rib, the at least one locating rib extending through the at least one locating slot, thereby preventing the sealing and flow guiding member from rotating relative to the bottle cap member.

[0013] In one embodiment of the present invention, the above-mentioned bottle cap member is coupled to the bottle mouth of the tire sealant bottle, thereby compressing the sealing portion between the bottle cap member and the bottle mouth of the tire sealant bottle, and connecting the air inlet hole and the air outlet hole with the internal space of the tire sealant bottle.

[0014] In one embodiment of the present invention, the above-mentioned bottle cap member has at least one cutting edge rib, and the at least one cutting edge rib is configured to cut a sealing film of a bottle mouth of a tire sealant bottle.

[0017] Based on the above, in the vehicle-mounted air compressor of the present invention, the seal and flow guide member not only provides the existing sealing function with its seal portion, but also covers the air inlet of the bottle cap member with its flow guide portion. Based on this, the high-pressure airflow from the air compressor body is guided by the flow guide portion to smoothly flow to the air outlet of the bottle cap member, and at the same time, the flow guide portion can prevent the tire sealant in the tire sealant bottle from flowing to the air inlet of the bottle cap member. In other words, the present invention covers the air inlet of the bottle cap member by integrally molding the flow guide portion with the existing seal member, so there is no need to add additional parts to achieve this purpose. As a result, the vehicle-mounted air compressor and its bottle cap assembly of the present invention can prevent the tire sealant from flowing to the air compressor body with a simple structure, and the difficulty of manufacturing and assembling the bottle cap assembly can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] FIG. 1 is a perspective 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 perspective view of the on-vehicle air compressor of FIG. 1 connected to a tire. With reference 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 seal and flow guide member 124. The bottle cap member 122 is provided on the air compressor body 110 and has an air introduction end 1221 and an air discharge end 1222, and the air introduction end 1221 and the air discharge end 1222 are, for example, columnar bodies protruding outward from the outer surface of the bottle cap member 122. The air introduction end 1221 is inserted into the air discharge pipe 112 of the air compressor body 110. The seal and flow guide 124 is made of, for example, rubber, silicone, or other types of elastic sealing materials, and is disposed in the bottle cap member 122. The tire sealant bottle 50 is adapted to be coupled to the bottle cap member 122. The bottle cap member 122 can be connected to the tire 60 via a connecting tube 130.

[0020] The high-pressure airflow from the air compressor body 110 is configured to enter the bottle cap member 122 through the air inlet end 1221 of the bottle cap member 122, passes through the bottle cap member 122 and the sealing and flow guiding member 124 in this order, and reaches the tire sealant bottle 50, and the high-pressure airflow causes the tire sealant in the tire sealant bottle 50 to pass through the sealing and flow guiding member 124 and the bottle cap member 122 in this order, and leaves the bottle cap member 122 through the air outlet end 1222 of the bottle cap member 122 and flows through the connecting pipe 130 to the tire 60, thereby achieving the effect of repairing and filling the tire with air. The method and principle of the air compressor body 110 generating the high-pressure airflow are known in the art and will not be described here.

[0021] FIG. 4 is a partial perspective view of the vehicle-mounted air compressor of FIG. 1. FIG. 5 is a partial cross-sectional view of the vehicle-mounted air compressor and the tire sealant bottle of FIG. 1. Referring to FIG. 4 and FIG. 5, specifically, the seal and flow guide member 124 is located in the bottle cap member 122 and includes a seal portion 1241 and a flow guide portion 1242, the seal portion 1241 surrounds the flow guide portion 1242, and the flow guide portion 1242 communicates between the air inlet end 1221 and the air outlet end 1222. The seal portion 1241 and the flow guide portion 1242 are of an integrally molded structure. That is, the seal and flow guide member 124 is not formed by combining a plurality of parts, but is a single member formed by integral molding. When the bottle mouth 52 of the tire sealant bottle 50 is connected to the bottle cap member 122, the bottle mouth 52 of the tire sealant bottle 50 presses downward on the sealing portion 1241 of the sealing and flow guiding member 124, compressing the sealing portion 1241 between the bottle cap member 122 and the bottle mouth 52 of the tire sealant bottle 50, thereby preventing the tire sealant in the tire sealant bottle 50 from leaking out through the gap between the bottle mouth 52 and the bottle cap member 122.

[0022] FIG. 6 is a perspective view of the bottle cap member and the seal and flow guide member of FIG. 2. FIG. 7 is a perspective view of the bottle cap member of FIG. 6. FIG. 8 is a perspective view of the seal and flow guide member of FIG. 6. Referring to FIG. 6 to FIG. 8, in detail, the bottle cap member 122 of this embodiment has an air inlet 122a and an air outlet 122b, the air inlet 122a communicates with the air inlet end 1221, and the air outlet 122b communicates with the air outlet end 1222. As a result, the inside of the bottle cap member 122 communicates with the air compressor body 110 through the air inlet 122a, and communicates with the connection pipe 130 through the air outlet 122b. In addition, the flow guide portion 1242 covers the air inlet 122a, and has at least one air inlet hole 1242a (shown as two) and one air outlet hole 1242b. The flow guide portion 1242 communicates with the air inlet 122a through the air inlet hole 1242a, and communicates with the air outlet 122b through the air outlet hole 1242b. When the bottle cap member 122 and the bottle mouth 52 of the tire sealant bottle 50 are interconnected as shown in Fig. 5, the air inlet hole 1242a and the air outlet hole 1242b of the flow guide portion 1242 communicate with the internal space of the tire sealant bottle 50. The high-pressure airflow from the air compressor main body 110 passes through the air inlet 122a, the air inlet hole 1242a, the internal space of the tire sealant bottle 50, the air outlet hole 1242b, and the air outlet 122b in this order.

[0023] In the above-mentioned arrangement, the seal and flow guide member 124 not only provides the existing sealing function by its seal portion 1241, but also covers the air inlet 122a of the bottle cap member 122 by its flow guide portion 1242. Based on this, the high-pressure airflow from the air compressor body 110 smoothly flows to the air outlet 122b of the bottle cap member 122 by the guide of the flow guide portion 1242, and at the same time, the flow guide portion 1242 can prevent the tire sealant in the tire sealant bottle 50 from flowing to the air inlet 122a of the bottle cap member 122. That is, in this embodiment, the air inlet 122a of the bottle cap member 122 is covered by integrally molding the flow guide portion 1242 with the existing seal member, so that there is no need to add a separate part to achieve this purpose. Therefore, the vehicle-mounted air compressor 100 and its bottle cap assembly 120 of this embodiment can prevent the flow of tire sealant into the air compressor body 110 with a simple structure, and can reduce the difficulty of manufacturing and assembling the bottle cap member 122.

[0024] Fig. 9 illustrates a partial structure of the vehicle-mounted air compressor and tire sealant bottle of Fig. 1. Fig. 10 illustrates a partial structure of the vehicle-mounted air compressor and tire sealant bottle of Fig. 1. Fig. 11 illustrates a partial structure of the bottle cap member and the seal and flow guide member of Fig. 6. With reference to Figs. 9 to 11, in detail, the gap between the seal and flow guide member 124 and the bottle cap member 122 of this embodiment forms a flow guide channel 120a, and the flow guide channel 120a communicates between the air inlet hole 1242a and the air outlet hole 1242b. The high-pressure airflow from the air compressor body 110 (shown in FIG. 1) passes through the air inlet end 1221, the air inlet 122a, the flow guide channel 120a, and the air inlet hole 1242a in this order along the flow path P1 shown in FIG. 9 before reaching the inside of the tire sealant bottle 50, and the tire sealant 501 inside the tire sealant bottle 50 flows along the flow path P2 shown in FIG. 10 along with the high-pressure airflow, passing through the air discharge hole 1242b, the air discharge port 122b, and the air discharge end 1222 in this order, and then through the connecting pipe 130 to the tire 60 (shown in FIG. 3).

[0025] 9 and 10, the flow guide channel 120a extends in a zigzag pattern, and the width of the flow guide channel 120a (i.e., the gap between the seal and flow guide member 124 and the bottle cap member 122) is smaller than the inner diameter of the air inlet 122a and the inner diameter of the air inlet hole 1242a. Based on this, the tire sealant having surface tension in the tire sealant bottle 50 does not flow through the flow guide channel 120a to the air inlet 122a of the bottle cap member 122. The width of the flow guide channel 120a is, for example, 0.1 to 0.3 mm, but the present invention is not limited thereto.

[0026] 8, in this embodiment, the flow guide portion 1242 of the seal and flow guide member 124 includes a boss C, the air inlet hole 1242a is located at the top end of the boss C, and the bottom end of the boss C is adjacent to the air discharge hole 1242b and the seal portion 1241. That is, the flow guide portion 1242 of the seal and flow guide member 124 includes a boss C, an air inlet hole 1242a formed at the top end of the boss C, and an air discharge hole 1242b adjacent to the bottom end of the boss C. The air inlet 122a and the flow guide channel 120a are located inside the boss C. When the tire sealant bottle 50 is connected to the bottle cap member 122, the boss C protrudes into the tire sealant bottle 50 to ensure that the air inlet hole 1242a is directed toward the internal space of the tire sealant bottle 50.

[0027] 6 to 8, in this embodiment, the seal and flow guide member 124 has a plurality of positioning slots 124a, and the bottle cap member 122 has two positioning ribs 1223 and two cutting edge ribs 1224. The two positioning ribs 1223 penetrate the positioning slots 124a and the air exhaust hole 1242b, respectively, and the two cutting edge ribs 1224 penetrate the other two positioning slots 124a, respectively, to prevent the seal and flow guide member 124 from rotating relative to the bottle cap member 122. From the above, in this embodiment, the tire sealant bottle 50 and the bottle cap member 122 are connected to each other by, for example, rotating relative to each other in a screw cap manner. When the tire sealant bottle 50 and the bottle cap member 122 rotate relative to each other during the connection process, the positioning design such as the positioning slots 124a and the positioning ribs 1223 described above can prevent the seal and flow guide member 124 from being twisted and deformed due to the rotation.

[0028] In addition, during the process of connecting the tire sealant bottle 50 and the bottle cap member 122, the cutting edge rib 1224 is configured to cut the sealing film on the bottle mouth 52 of the tire sealant bottle 50, thereby smoothly connecting the sealing and flow guiding member 124 to the internal space of the tire sealant bottle 50.

[0029] 2 and 4, in this embodiment, the vehicle-mounted air compressor 100 further includes a position limiting member 140 and at least one fastening member 150 (two shown). The position limiting member 140 limits the position of the bottle cap member 122 on the air compressor body 110, and the fastening member 150 is, for example, a screw, and fastens the position limiting member 140 to the air compressor body 110. Based on this, a user only needs to simply install the bottle cap member 122 on the air compressor body 110 and install the position limiting member 140 to complete the installation of the bottle cap member 122, and a user only needs to remove the position limiting member 140 and then remove the bottle cap member 122 to complete the removal of the bottle cap member 122 and / or the replacement of the tire sealant bottle 50. More specifically, the fastening direction of the fastening member 150 is, for example, the same as the insertion direction of the air introduction end 1221 of the bottle cap member 122 (direction D shown in FIG. 2), and the fastening position of the fastening member 150 and the insertion position of the air introduction end 1221 of the bottle cap member 122 are both located on the same side of the air compressor body 110 (i.e., the upper side of the air compressor body 110), thereby allowing the user to conveniently assemble the vehicle-mounted air compressor 100 at the same position and in the same working direction. In addition, since the fastening direction of the fastening member 150 is the same as the insertion direction of the air introduction end 1221 of the bottle cap member 122, the air introduction end 1221 can be stably inserted into the air compressor 100 by fastening the fastening member 150.

[0030] The operation flow of the vehicle-mounted air compressor of this embodiment will be described below.

[0031] Figures 12A to 12E are operation flow diagrams of the vehicle-mounted air compressor of Figure 1. Figures 13A to 13C are top views of the vehicle-mounted air compressor of Figures 12A to 12C, respectively. First, as shown in Figures 12A and 13A, connecting tube 130 is placed over air discharge end 1222 of bottle cap member 122 and attached, and connecting tube 130 is fastened to air discharge end 1222 using tube clamp 160. 12B and 13B, 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 100, the bottle cap member 122 is positioned by the two locking hooks 114 of the air compressor body 100, and at the same time, the air inlet end 1221 of the bottle cap member 122 is inserted into the air discharge pipe 112 of the air compressor body 110, and the air discharge pipe 112 is communicated with the air inlet port 122a. The gap between the air inlet end 1221 and the air discharge pipe 112 is sealed by a seal ring 170 provided to cover the air inlet end 1221. In addition, the top surface of the air compressor body 110 has an opening 110a, and the interconnection point between the air discharge pipe 112 and the bottle cap member 122 corresponds to the opening 110a as shown in FIG. 13B, allowing the user to visually check through the opening 110a whether the air discharge pipe 112 and the bottle cap member 122 are securely connected.

[0032] 12C and 13C, the fastening member 150 fastens the position limiting member 140 to the air compressor body 110 to the state shown in FIG. 12D, causing the position limiting member 140 to clamp the bottle cap member 122 to the air compressor body 110 and press the position limiting member 140 against the connecting pipe 130. Next, as shown in FIG. 12D to FIG. 12E, the bottle mouth 52 of the tire sealant bottle 50 is coupled to the bottle cap member 122, and in this process, the sealing film 52a at the bottle mouth 52 is cut by the cutting edge rib 1224 (shown in FIG. 7) of the bottle cap member 122, allowing the high-pressure airflow from the air compressor body 110 to enter the tire sealant bottle 50 along the flow path P1 in the subsequent tire repair and air filling operation, and allowing the tire sealant 501 in the tire sealant bottle 50 to leave the tire sealant bottle 50 along the flow path P2 accompanied by the high-pressure airflow in the subsequent tire repair and air filling operation. Finally, as shown in FIG. 3, by connecting the connecting pipe 130 to the tire 60, the vehicle-mounted air compressor 100 can start repairing and filling the tire 60 with air.

[0033] FIG. 14 illustrates the tire sealant bottle of FIG. 1 being replaced with a cover body. FIG. 15 illustrates the tire sealant bottle of FIG. 2 being replaced with a cover body. FIG. 16A illustrates the tire sealant bottle of FIG. 12D being replaced with a cover body. FIG. 16B illustrates the tire sealant bottle of FIG. 12E being replaced with a cover body. The vehicle-mounted air compressor 100 of this embodiment only fills the tire 60 with air, and does not perform tire repair on the tire 60. Specifically, the tire sealant bottle 50 in FIG. 1, FIG. 2, FIG. 12D, and FIG. 12E is replaced with the cover body 70 in FIG. 14, FIG. 15, FIG. 16A, and FIG. 16B, and the remaining operation flow is the same as that described above, and will not be repeated here. The methods shown in Figures 14, 15, 16A, and 16B do not use tire sealant bottle 50, and therefore, as shown by flow path P3 in Figure 16B, the high-pressure air flow from air compressor body 110 passes through bottle cap assembly 120 and then reaches the tire directly to fill it with air.

[0034] To sum up, in the vehicle-mounted air compressor of the present invention, the seal and flow guide member not only provides the existing sealing function with its seal portion, but also covers the air inlet of the bottle cap member with its flow guide portion. Based on this, the high-pressure airflow from the air compressor body is guided by the flow guide portion to smoothly flow to the air outlet of the bottle cap member, and at the same time, the flow guide portion can prevent the tire sealant in the tire sealant bottle from flowing to the air inlet of the bottle cap member. In other words, the present invention covers the air inlet of the bottle cap member by integrally molding the flow guide portion with the existing seal member, so there is no need to add additional parts to achieve this purpose. As a result, the vehicle-mounted air compressor and bottle cap assembly of the present invention can prevent the tire sealant from flowing to the air compressor body with a simple structure, and the difficulty of manufacturing and assembling the bottle cap assembly can be reduced.
