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] An on-board air compressor can be used with a tire sealant bottle to repair or inflate a vehicle tire, or can be used without a tire sealant bottle to inflate a vehicle tire. Generally, when repairing or inflating a tire, a bottle cap assembly must be provided on the air compressor body of the on-board air compressor to connect with the tire sealant bottle, and high-pressure air from the air compressor body must be directed through the bottle cap assembly into the tire sealant bottle, thereby forcing the tire sealant in the tire sealant bottle into the tire, thereby achieving the effect of repairing or inflating the tire.

[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 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-described situation, 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]

[0004] The present invention provides an on-vehicle air compressor and a bottle cap assembly therefor that can prevent tire sealant from flowing into the air compressor body with a simple structure. [Means for solving the problem]

[0005] The vehicle-mounted air compressor of the present invention includes an air compressor body and a bottle cap assembly. The bottle cap assembly includes a bottle cap member and a seal and flow guide member. The bottle cap member is attached to the air compressor body and has an air inlet and an air outlet, and the bottle cap member communicates with the air compressor body through the air inlet. The seal and flow guide member is disposed on the bottle cap member and includes a sealing portion and a flow guide portion. The sealing portion surrounds the flow guide portion, and the flow guide portion covers the air inlet and has at least one air inlet hole and one air outlet hole. The flow guide portion communicates with the air inlet through the air inlet hole and with the air outlet through the air outlet hole. Airflow from the air compressor body passes through the air inlet, air inlet hole, air outlet hole, and air outlet hole, in that order.

[0006] The bottle cap assembly of the present invention is applicable to an on-vehicle air compressor and includes a bottle cap member and a seal and flow guide member. The bottle cap member is attached to the 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. The seal and flow guide member is disposed on the bottle cap member and includes a sealing portion and a flow guide portion. The sealing portion surrounds the flow guide portion, and the flow guide portion covers the air inlet and has at least one air inlet hole and one air outlet hole. The flow guide portion communicates with the air inlet through the air inlet hole and with the air outlet through the air outlet hole. Airflow from the air compressor body passes through the air inlet, air inlet hole, air outlet hole, and air outlet hole in that order.

[0007] In one embodiment of the present invention, the sealing portion and the flow guide portion are of an integrally molded structure.

[0008] In one embodiment of the present invention, a flow guide channel is formed between the sealing and flow guide member and the bottle cap member, and the flow guide channel communicates with at least one air inlet hole and an air outlet hole.

[0009] In one embodiment of the present invention, the width of the above-mentioned flow guiding channel is smaller than the inner diameter of the air inlet and the inner diameter of the at least one air inlet hole.

[0010] In one embodiment of the present invention, the flow guiding channels described above extend in a zigzag pattern.

[0011] In one embodiment of the present invention, the above-mentioned flow guide includes a boss, and 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 outlet 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, which passes through the at least one locating slot to prevent 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 bottle cap member described above has at least one cutting edge rib, and the at least one cutting edge rib is configured to cut the sealing film of the bottle mouth of the tire sealant bottle.

[0015] In one embodiment of the present invention, the above-mentioned vehicle-mounted air compressor further includes a position limiting member and at least one fastening member, wherein the position limiting member limits the position of the bottle cap member on the air compressor body, and the at least one fastening member fastens the position limiting member to the air compressor body.

[0016] In one embodiment of the present invention, the above-mentioned air compressor body includes an air discharge pipe, and the air discharge pipe is connected to the bottle cap member to communicate with the air inlet, and the top surface of the air compressor body has an opening, and the interconnection point between the air discharge pipe and the bottle cap member corresponds to the opening. [Effects of the Invention]

[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 flow guide portion guides the high-pressure airflow from the air compressor body, allowing it to flow smoothly to the air outlet of the bottle cap member, while the flow guide portion prevents tire sealant from the tire sealant bottle from flowing into 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 into the existing seal member, thereby eliminating the need for additional parts to achieve this purpose. As a result, the vehicle-mounted air compressor and its bottle cap assembly of the present invention prevent tire sealant from flowing into the air compressor body with a simple structure, reducing the difficulty of manufacturing and assembling the bottle cap assembly.

[0019] FIG. 1 is a perspective view of an on-vehicle air compressor and a tire sealant bottle according to one embodiment of the present invention. FIG. 2 is an exploded view of the on-vehicle air compressor and 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. Referring to FIGS. 1 to 3, an on-vehicle air compressor 100 according to this embodiment includes an air compressor main body 110, a bottle cap assembly 120, and a connecting 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 main body 110 and has an air inlet end 1221 and an air outlet end 1222, both of which are, for example, columnar bodies protruding outward from the outer surface of the bottle cap member 122. The air inlet end 1221 is inserted into an air outlet pipe 112 of the air compressor main body 110. The seal and flow guide 124 is made of, for example, rubber, silicone, or other types of elastic sealing material, and is disposed on 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, pass through the bottle cap member 122 and the sealing and flow guiding member 124 in that order, and reach the tire sealant bottle 50. 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 that order, and then leave the bottle cap member 122 through the air outlet end 1222 of the bottle cap member 122 and flow through the connecting tube 130 into the tire 60, thereby achieving the effects of repairing and inflating the tire. The method and principle by which the air compressor body 110 generates 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 tire sealant bottle of FIG. 1. Referring to FIGS. 4 and 5, specifically, the seal and flow guide member 124 is located within 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 have an integrally molded structure. That is, the seal and flow guide member 124 is not formed by combining multiple parts, but is a single, integrally molded member. 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 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 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 / 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 / flow guide member of FIG. 6. Referring to FIGS. 6 to 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 communicating with the air introduction end 1221, and the air outlet 122b communicating with the air outlet end 1222. As a result, the interior of the bottle cap member 122 communicates with the air compressor body 110 through the air inlet 122a and with the connecting 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 (two shown) and one air outlet hole 1242b. The flow guide portion 1242 communicates with the air inlet 122a through the air inlet hole 1242a and 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 interior space of the tire sealant bottle 50. The high-pressure airflow from the air compressor body 110 passes through the air inlet 122a, the air inlet hole 1242a, the interior space of the tire sealant bottle 50, the air outlet hole 1242b, and the air outlet 122b, in that order.

[0023] In the above-described arrangement, the seal and flow guide member 124 not only provides the existing sealing function with its seal portion 1241, but also covers the air inlet port 122a of the bottle cap member 122 with its flow guide portion 1242. Based on this, the high-pressure airflow from the air compressor body 110 is guided by the flow guide portion 1242 to smoothly flow to the air outlet port 122b of the bottle cap member 122, and at the same time, the flow guide portion 1242 can prevent the tire sealant in the tire sealant bottle 50 from flowing into the air inlet port 122a of the bottle cap member 122. That is, in this embodiment, the flow guide portion 1242 is integrally molded with the existing seal member to cover the air inlet port 122a of the bottle cap member 122, so there is no need to add an additional part to achieve this purpose. Therefore, the vehicle-mounted air compressor 100 and its bottle cap assembly 120 of this embodiment can prevent the tire sealant from flowing 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] Figure 9 illustrates a partial structure of the vehicle-mounted air compressor and tire sealant bottle of Figure 1. Figure 10 illustrates a partial structure of the vehicle-mounted air compressor and tire sealant bottle of Figure 1. Figure 11 illustrates a partial structure of the bottle cap member and seal and flow guide member of Figure 6. Referring to Figures 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 with the air inlet hole 1242a and the air outlet hole 1242b. The high-pressure airflow from the air compressor main body 110 (shown in FIG. 1) passes along the flow path P1 shown in FIG. 9, passing through the air introduction end 1221, the air introduction port 122a, the flow guide channel 120a, and the air introduction hole 1242a in that order, before reaching the inside of the tire sealant bottle 50. 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 that order, and then flows 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 port 122a and the inner diameter of the air inlet hole 1242a. Based on this, the tire sealant having surface tension inside the tire sealant bottle 50 does not flow through the flow guide channel 120a to the air inlet port 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 to this.

[0026] 8 , in this embodiment, the flow guide portion 1242 of the seal and flow guide member 124 includes a boss C, with the air inlet hole 1242a located at the top end of the boss C and the bottom end of the boss C 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 the boss C, the air inlet hole 1242a formed at the top end of the boss C, and the air discharge hole 1242b adjacent to the bottom end of the boss C. The air inlet port 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 interior 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 respectively pass through the positioning slots 124a and the air discharge holes 1242b, and the two cutting edge ribs 1224 respectively pass through the other two positioning slots 124a, thereby preventing the seal and flow guide member 124 from rotating relative to the bottle cap member 122. As described above, in this embodiment, the tire sealant bottle 50 and the bottle cap member 122 are interconnected, for example, by rotating relative to each other, using a screw cap method. 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, 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 allowing the sealing and flow guiding member 124 to smoothly communicate with 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 members are 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 can complete the installation of the bottle cap member 122 by simply placing the bottle cap member 122 on the air compressor body 110 and installing the position limiting member 140. After that, a user can complete the removal of the bottle cap member 122 and / or the replacement of the tire sealant bottle 50 by simply removing the position limiting member 140 and then removing the bottle cap member 122. More specifically, the fastening direction of the fastening member 150 is, for example, the same as the insertion direction of the air inlet 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 inlet 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 in the same position and in the same working direction. Furthermore, because 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 stably inserted into the air compressor 100 by fastening the fastening member 150.

[0030] The operation flow of the vehicle 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 pipe 130 is placed over air discharge end 1222 of bottle cap member 122 and attached, and connecting pipe 130 is fastened to air discharge end 1222 using pipe clamp 160. 12B and 13B, the bottle cap member 122 is attached to the air compressor body 110 using the two guide surfaces 116 of the air compressor 100 as a guide, and the bottle cap member 122 is positioned using the two locking hooks 114 of the air compressor body 100. 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, so that the air discharge pipe 112 communicates 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 Figure 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 reach 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 Figs. 12D to 12E, the bottle mouth 52 of the tire sealant bottle 50 is coupled to the bottle cap member 122, and in the process, the sealing film 52a on 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 flow path P1 during the subsequent tire repair and air inflation operation, and allowing the tire sealant 501 in the tire sealant bottle 50 to leave the tire sealant bottle 50 along flow path P2 along with the high-pressure airflow during the subsequent tire repair and air inflation 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 inflates the tire 60 with air, and does not perform tire repair on the tire 60. Specifically, the tire sealant bottle 50 in FIGS. 1, 2, 12D, and 12E is replaced with the cover body 70 in FIGS. 14, 15, 16A, and 16B, and the remaining operational 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 main body 110 passes through bottle cap assembly 120 and then reaches the tire directly to fill it with air.

[0034] To summarize 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 flow guide portion guides the high-pressure airflow from the air compressor body, allowing it to flow smoothly to the air outlet of the bottle cap member, while the flow guide portion prevents tire sealant from the tire sealant bottle from flowing into 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 into the existing seal member, thereby eliminating the need for additional parts to achieve this purpose. As a result, the vehicle-mounted air compressor and bottle cap assembly of the present invention prevents tire sealant from flowing into the air compressor body with a simple structure and reduces the difficulty of manufacturing and assembling the bottle cap assembly.
