Description

Vehicle-mounted air compressor and bottle cap assembly

This novel invention relates to an air compressor, and in particular to a vehicle-mounted air compressor.

The vehicle-mounted air compressor can be used with a tire repair rubber container to repair and inflate the vehicle's tires, and can also be used to inflate the vehicle's tires without the tire repair rubber container. Generally speaking, when performing tire repair and inflation operations, a bottle cap assembly must be installed on the air compressor body of the vehicle-mounted air compressor to combine with the tire repair rubber container, and the high-pressure air from the air compressor body passes through the bottle cap assembly and enters the tire repair rubber container, and then the high-pressure airflow drives the tire repair rubber in the tire repair rubber container into the tire, achieving the effect of tire repair and inflation.

If the tire repairing rubber in the tire repairing rubber container accidentally flows through the bottle cap assembly to the air compressor body, the air compressor body may not be able to operate normally. If additional parts are added to the bottle cap assembly to prevent the tire repairing rubber from flowing into the air compressor body in order to avoid the above situation, the number of parts and the difficulty of manufacturing and assembling the bottle cap assembly will increase.

This novel invention provides a vehicle-mounted air compressor and its bottle cap assembly, which prevents tire repair rubber from flowing into the air compressor body through a simple structure.

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 sealing guide member. The bottle cap member is installed on the air compressor body and has an air inlet and an air outlet, and the bottle cap member is connected to the air compressor body through the air inlet. The sealing guide member is arranged on the bottle cap member and includes a sealing portion and a guide member. The sealing portion surrounds the guide member, and the guide member covers the air inlet and has at least one air inlet hole and one air outlet hole. The guide member is connected to the air inlet through the air inlet hole and is connected to the air outlet through the air outlet hole. The airflow from the air compressor body is suitable for passing through the air inlet, the air inlet hole, the air outlet hole and the air outlet in sequence.

The bottle cap assembly of the novel invention is suitable for a vehicle-mounted air compressor, including a bottle cap and a sealing guide. The bottle cap is installed on an air compressor body of the vehicle-mounted air compressor and has an air inlet and an air outlet. The bottle cap is connected to the air compressor body through the air inlet. The sealing guide is arranged on the bottle cap and includes a sealing part and a guide. The sealing part surrounds the guide, the guide covers the air inlet and has at least one air inlet hole and one air outlet. The guide is connected to the air inlet through the air inlet and connected to the air outlet through the air outlet. The airflow from the air compressor body is suitable for passing through the air inlet, the air inlet, the air outlet and the air outlet in sequence.

In one embodiment of the present invention, the sealing portion and the flow guide portion are an integrally formed structure.

In one embodiment of the present invention, a flow guide channel is formed between the sealing flow guide member and the bottle cap member, and the flow guide channel is connected between at least one air inlet and an air outlet.

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

In one embodiment of the present invention, the above-mentioned flow guide channel extends in a tortuous manner.

In one embodiment of the present invention, the above-mentioned air guide portion includes a boss, at least one air inlet is located at the top of the boss, and the bottom of the boss is adjacent to the air outlet and the sealing portion.

In one embodiment of the present invention, the sealing guide member has at least one positioning groove, and the bottle cap has at least one positioning rib, and the at least one positioning rib passes through at least one positioning groove to prevent the sealing guide member from rotating relative to the bottle cap.

In one embodiment of the present invention, the bottle cap is adapted to engage with a bottle mouth of a tire repairing rubber container bottle, so that the sealing portion is compressed between the bottle cap and the bottle mouth of the tire repairing rubber container bottle, and the air inlet and the air outlet are connected to the internal space of the tire repairing rubber container bottle.

In one embodiment of the present invention, the bottle cap has at least one cutting edge rib, and at least one cutting edge rib is suitable for cutting the sealing film on the bottle mouth of the tire repairing rubber container bottle.

In one embodiment of the present invention, the vehicle-mounted air compressor further includes a limiter and at least one fastener, wherein the limiter limits the bottle cap to the air compressor body, and at least one fastener fastens the limiter to the air compressor body.

In one embodiment of the present invention, the air compressor body has an air outlet pipe, which is connected to the bottle cap to communicate with the air inlet. The top of the air compressor body has an opening, and the connection between the air outlet pipe and the bottle cap corresponds to the opening.

Based on the above, in the vehicle-mounted air compressor of the present invention, the sealing guide member not only provides the existing sealing function through its sealing part, but also covers the air inlet of the bottle cap part through its guide part. Accordingly, while the high-pressure airflow from the air compressor body flows smoothly to the air outlet of the bottle cap part through the guidance of the guide part, the guide part can prevent the tire repairing rubber in the tire repairing rubber storage bottle from flowing to the air inlet of the bottle cap part. In other words, the present invention forms the guide part integrally on the existing sealing member to cover the air inlet of the bottle cap part, so no additional parts are needed to achieve this purpose. Therefore, the vehicle-mounted air compressor and its bottle cap assembly of the new invention can prevent the tire repair rubber from flowing into the air compressor body through a simple structure, thereby reducing the difficulty of manufacturing and assembling the bottle cap assembly.

FIG. 1 is a three-dimensional diagram of a vehicle-mounted air compressor and a tire repairing rubber container bottle of an embodiment of the present invention. FIG. 2 is an exploded view of the vehicle-mounted air compressor and the tire repairing rubber container bottle of FIG. 1. FIG. 3 is a three-dimensional diagram of the vehicle-mounted air compressor of FIG. 1 connected to a tire. Referring to FIG. 1 to FIG. 3, the vehicle-mounted air compressor 100 of the present embodiment includes an air compressor 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 sealing guide member 124. The bottle cap 122 is mounted on the air compressor body 110 and has an air inlet 1221 and an air outlet 1222. The air inlet 1221 and the air outlet 1222 are, for example, cylindrical bodies protruding outward from the outer surface of the bottle cap 122. The air inlet 1221 is suitable for plugging into an air outlet pipe 112 of the air compressor body 110. The sealing guide 124 is made of, for example, rubber, silicone or other types of elastic sealing materials and is disposed on the bottle cap 122. The tire repairing rubber container 50 is used to be connected to the bottle cap 122. The bottle cap 122 can be connected to the tire 60 through the connecting tube 130.

The high-pressure airflow from the air compressor body 110 is suitable for entering the bottle cap 122 through the air inlet end 1221 of the bottle cap 122, and sequentially passes through the bottle cap 122 and the sealing guide 124 to reach the tire repair rubber container bottle 50, and then the high-pressure airflow drives the tire repair rubber in the tire repair rubber container bottle 50 to sequentially pass through the sealing guide 124 and the bottle cap 122 and leave the bottle cap 122 through the air outlet end 1222 of the bottle cap 122 and flow to the tire 60 through the connecting pipe 130, thereby achieving the effect of tire repair and inflation. The method and principle of the air compressor body 110 to generate high-pressure airflow are known in the art and will not be elaborated here.

FIG4 is a partial three-dimensional view of the vehicle-mounted air compressor of FIG1. FIG5 is a partial cross-sectional view of the vehicle-mounted air compressor and the tire repair rubber container of FIG1. Referring to FIG4 and FIG5, specifically, the sealing guide member 124 is located in the bottle cap member 122 and includes a sealing portion 1241 and a guide portion 1242. The sealing portion 1241 surrounds the guide portion 1242, and the guide portion 1242 is connected between the air inlet end 1221 and the air outlet end 1222. The sealing portion 1241 and the guide portion 1242 are an integrally formed structure, that is, the sealing guide member 124 is a single component formed in an integral form rather than being composed of a plurality of parts. When the bottle mouth 52 of the tire repairing rubber container bottle 50 is connected to the bottle cap 122, the bottle mouth 52 of the tire repairing rubber container bottle 50 presses down the sealing portion 1241 of the sealing guide member 124, so that the sealing portion 1241 is compressed between the bottle cap 122 and the bottle mouth 52 of the tire repairing rubber container bottle 50, thereby preventing the tire repairing rubber in the tire repairing rubber container bottle 50 from flowing out through the gap between the bottle mouth 52 and the bottle cap 122.

FIG. 6 is a three-dimensional view of the bottle cap and the sealing guide of FIG. 2 . FIG. 7 is a three-dimensional view of the bottle cap of FIG. 6 . FIG. 8 is a three-dimensional view of the sealing guide of FIG. 6 . Please refer to FIG. 6 to FIG. 8 , in detail, the bottle cap 122 of this embodiment has an air inlet 122a and an air outlet 122b, the air inlet 122a is connected to the air inlet end 1221, and the air outlet 122b is connected to the air outlet end 1222. Therefore, the interior of the bottle cap 122 can be connected to the air compressor body 110 through the air inlet 122a and can be connected to the connecting pipe 130 through the air outlet 122b. Furthermore, the air guide portion 1242 covers the air inlet 122a and has at least one air inlet hole 1242a (two are shown) and an air outlet hole 1242b. The air guide portion 1242 is connected to the air inlet 122a through the air inlet hole 1242a and is connected to the air outlet 122b through the air outlet hole 1242b. When the bottle cap 122 and the bottle mouth 52 of the tire repairing rubber accommodating bottle 50 are engaged with each other as shown in FIG. 5 , the air inlet hole 1242a and the air outlet hole 1242b of the air guide portion 1242 are connected to the inner space of the tire repairing rubber accommodating bottle 50. The high-pressure air flow from the air compressor body 110 is suitable for sequentially passing through the air inlet 122a, the air inlet hole 1242a, the internal space of the tire repair rubber container 50, the air outlet hole 1242b and the air outlet 122b.

Under the above configuration, the sealing guide member 124 not only provides the existing sealing function through its sealing portion 1241, but also covers the air inlet 122a of the bottle cap member 122 through its guide portion 1242. Accordingly, while the high-pressure airflow from the air compressor body 110 flows smoothly to the air outlet 122b of the bottle cap member 122 under the guidance of the guide portion 1242, the guide portion 1242 can prevent the tire repairing rubber in the tire repairing rubber storage bottle 50 from flowing to the air inlet 122a of the bottle cap member 122. In other words, the present embodiment forms the guide portion 1242 integrally on the existing sealing member to cover the air inlet 122a of the bottle cap member 122, so no additional parts are needed to achieve this purpose. Therefore, the vehicle-mounted air compressor 100 and its bottle cap assembly 120 of this embodiment can reduce the difficulty of manufacturing and assembling the bottle cap assembly 120 by preventing the tire repair rubber from flowing into the air compressor body 110 through a simple structure.

FIG9 shows a partial structure of the vehicle-mounted air compressor and tire repair rubber container bottle of FIG1. FIG10 shows a partial structure of the vehicle-mounted air compressor and tire repair rubber container bottle of FIG1. FIG11 shows a partial structure of the bottle cap and the sealing guide member of FIG6. Please refer to FIG9 to FIG11, in more detail, a guide channel 120a is formed between the sealing guide member 124 and the bottle cap member 122 of this embodiment, and the guide channel 120a is connected between the air inlet 1242a and the air outlet 1242b. The high-pressure airflow from the air compressor body 110 (shown in FIG. 1 ) can sequentially pass through the air inlet 1221, the air inlet 122a, the guide channel 120a and the air inlet 1242a along the flow path P1 shown in FIG. 9 to reach the inside of the tire repairing rubber container 50, and the tire repairing rubber 501 inside the tire repairing rubber container 50 can flow along the flow path P2 shown in FIG. 10 sequentially through the air outlet 1242b, the air outlet 122b and the air outlet 1222 through the connecting tube 130 to the tire 60 (shown in FIG. 3 ).

Furthermore, the guide channel 120a extends in a zigzag manner as shown in FIG9 and FIG10, and the inner diameter of the guide channel 120a is smaller than the inner diameter of the air inlet 122a and the inner diameter of the air inlet hole 1242a. Accordingly, it can be ensured that the tire repairing rubber with surface tension in the tire repairing rubber storage bottle 50 will not flow to the air inlet 122a of the bottle cap 122 through the guide channel 120a. The inner diameter of the guide channel 120a is, for example, 0.1~0.3mm, but the present invention is not limited thereto.

Please refer to FIG8 . In this embodiment, the guide portion 1242 of the sealing guide member 124 includes a boss C, the air inlet 1242a is located at the top of the boss C, and the bottom of the boss C is adjacent to the air outlet 1242b and the sealing portion 1241. That is, the guide portion 1242 of the sealing guide member 124 includes the boss C, the air inlet 1242a formed at the top of the boss C, and the air outlet 1242b adjacent to the bottom of the boss C. The air inlet 122a and the guide channel 120a are located inside the boss C. When the tire repair rubber container bottle 50 is connected to the bottle cap 122, the boss C protrudes into the tire repair rubber container bottle 50 and makes the air inlet 1242a face the inner space of the tire repair rubber container bottle 50.

Please refer to Figures 6 to 8. In this embodiment, the sealing guide member 124 has a plurality of positioning slots 124a, and the bottle cap member 122 has two positioning ribs 1223 and two cutting ribs 1224. The two positioning ribs 1223 pass through one positioning slot 124a and the air outlet 1242b respectively, and the two cutting ribs 1224 pass through the other two positioning slots 124a respectively, so as to prevent the sealing guide member 124 from rotating relative to the bottle cap member 122. As mentioned above, in this embodiment, the tire repairing rubber accommodating bottle 50 and the bottle cap member 122 are engaged with each other in a screw-on manner, for example, by rotating relative to each other. When the tire repairing rubber container bottle 50 and the bottle cap 122 rotate relative to each other during the joining process, the positioning design of the positioning groove 124a and the positioning rib 1223 can prevent the sealing guide member 124 from being twisted and deformed due to the rotation.

In addition, during the joining process between the tire repairing rubber container bottle 50 and the bottle cap 122, the cutting blade rib 1224 is suitable for cutting the sealing film on the bottle mouth 52 of the tire repairing rubber container bottle 50, so that the sealing guide member 124 is smoothly connected to the internal space of the tire repairing rubber container bottle 50.

Please refer to FIG. 2 and FIG. 4 . In this embodiment, the vehicle-mounted air compressor 100 further includes a stopper 140 and at least one fastener 150 (two are shown). The stopper 140 stops the bottle cap 122 at the air compressor body 110, and the fastener 150 is, for example, a screw and fastens the stopper 140 to the air compressor body 110. Accordingly, the user only needs to simply install the bottle cap 122 to the air compressor body 110 and then install the stopper 140 to complete the installation of the bottle cap 122, and the user only needs to simply remove the stopper 140 and then remove the bottle cap 122 to complete the removal of the bottle cap 122 and/or the replacement of the tire repair rubber container 50. Furthermore, the fastening direction of the fastener 150 is, for example, the same as the plugging direction of the air inlet end 1221 of the bottle cap 122 (direction D shown in FIG. 2 ), and the fastening position of the fastener 150 and the plugging position of the air inlet end 1221 of the bottle cap 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), so that the user can 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 fastener 150 is the same as the plugging direction of the air inlet end 1221 of the bottle cap 122, the air inlet end 1221 can be stably plugged into the air compressor body 110 by fastening the fastener 150.

The following describes the operation process of the vehicle-mounted air compressor of this embodiment.

Fig. 12A to Fig. 12E are operation flow charts of the vehicle-mounted air compressor of Fig. 1. Fig. 13A to Fig. 13C are top views of the vehicle-mounted air compressor of Fig. 12A to Fig. 12C, respectively. First, as shown in Fig. 12A and Fig. 13A, the connecting tube 130 is sleeved on the air outlet end 1222 of the bottle cap 122, and a tube clamp 160 is used to fasten the connecting tube 130 to the air outlet end 1222. Next, as shown in FIG. 12B and FIG. 13B , the bottle cap 122 is installed on the compressor body 110 by the guidance of the two guide surfaces 116 of the compressor body 110, and the bottle cap 122 is positioned by the two hooks 114 of the compressor body 110, and at the same time, the air inlet end 1221 of the bottle cap 122 is plugged into the air outlet pipe 112 of the compressor body 110, so that the air outlet pipe 112 is connected to the air inlet 122a. The gap between the air inlet end 1221 and the air outlet pipe 112 can be sealed by a sealing ring 170 sleeved on the air inlet end 1221. In addition, the top of the air compressor body 110 has an opening 110a, and the air outlet pipe 112 and the bottle cap 122 are connected to each other. As shown in FIG. 13B, the opening 110a corresponds to the user's visual confirmation through the opening 110a whether the air outlet pipe 112 and the bottle cap 122 are indeed connected.

Then, as shown in FIG. 12C and FIG. 13C , the stopper 140 is fastened to the compressor body 110 by the fastener 150 to form the state shown in FIG. 12D , so that the stopper 140 presses the bottle cap member 122 against the compressor body 110 and the stopper 140 presses the connecting pipe 130 . Next, as shown in FIGS. 12D to 12E , the bottle mouth 52 of the tire repairing rubber container bottle 50 is joined to the bottle cap 122. During this process, the sealing film 52a at the bottle mouth 52 is cut by the cutting blade rib 1224 (shown in FIG. 7 ) of the bottle cap 122, so that the high-pressure air flow from the air compressor body 110 can enter the tire repairing rubber container bottle 50 along the flow path P1 during the subsequent tire repairing and inflation operations, and the tire repairing rubber 501 in the tire repairing rubber container bottle 50 can leave the tire repairing rubber container bottle 50 along the flow path P2 during the subsequent tire repairing and inflation operations along with the high-pressure air flow. Finally, as shown in FIG3 , the connecting tube 130 is connected to the tire 60, and the tire 60 can be repaired and inflated by the vehicle-mounted air compressor 100.

FIG14 shows that the tire repairing rubber container bottle in FIG1 is replaced by a cover. FIG15 shows that the tire repairing rubber container bottle in FIG2 is replaced by a cover. FIG16A shows that the tire repairing rubber container bottle in FIG12D is replaced by a cover. FIG16B shows that the tire repairing rubber container bottle in FIG12E is replaced by a cover. The vehicle-mounted air compressor 100 of this embodiment can also only inflate the tire 60 without repairing the tire 60. Specifically, the tire repairing rubber container bottle 50 in FIG1, FIG2, FIG12D, and FIG12E can be replaced by the cover 70 in FIG14, FIG15, FIG16A, and FIG16B, and the rest of the operation process is the same as the above, which will not be elaborated here. Since the method shown in Figures 14, 15, 16A, and 16B does not use the tire repair rubber container bottle 50, the high-pressure air from the air compressor body 110 flows through the bottle cap assembly 120 and directly reaches the tire for inflation, as shown in the flow path P3 of Figure 16B.

In summary, in the vehicle-mounted air compressor of the present invention, the sealing guide member not only provides the existing sealing function by means of its sealing part, but also covers the air inlet of the bottle cap part by means of its guide part. Accordingly, while the high-pressure airflow from the air compressor body flows smoothly to the air outlet of the bottle cap part by means of the guide part, the guide part can prevent the tire repairing rubber in the tire repairing rubber storage bottle from flowing to the air inlet of the bottle cap part. In other words, the present invention forms the guide part integrally on the existing sealing part to cover the air inlet of the bottle cap part, so no additional parts are needed to achieve this purpose. Therefore, the vehicle-mounted air compressor and its bottle cap assembly of the new invention can prevent the tire repair rubber from flowing into the air compressor body through a simple structure, thereby reducing the difficulty of manufacturing and assembling the bottle cap assembly.
