Vehicle-mounted air compressor

The present 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 bottle to repair and inflate the tires of the vehicle, and can also be used to inflate the tires of the vehicle without a tire repair bottle. 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 bottle, and the high-pressure air from the air compressor body passes through the bottle cap assembly and enters the tire repair bottle, and then the high-pressure air flow drives the tire repair rubber in the tire repair bottle into the tire, achieving the effect of inflation and tire repair.

Due to factors such as the limited space on the air compressor body, the location and fastening direction of the fastening structure between the air compressor body and the bottle cap assembly are usually not very user-friendly, making it difficult for users to easily install the bottle cap assembly on the air compressor body.

The present invention provides a vehicle-mounted air compressor and a bottle cap assembly thereof, which enables the bottle cap assembly to be easily and simply assembled to the air compressor body.

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 at least one fastener. The bottle cap member is installed on the air compressor body and has an air inlet end and an air outlet end that are connected to each other. The bottle cap member is plugged into the air compressor body along a plugging direction through the air inlet end. The air flow from the air compressor body is suitable for passing through the air inlet end and the air outlet end in sequence. The fastener fastens the bottle cap member to the air compressor body along a fastening direction. The fastening direction is the same as the plugging direction.

The bottle cap assembly of the present invention is suitable for a vehicle-mounted air compressor, and includes a bottle cap and at least one fastener. The bottle cap is installed on an air compressor body of the vehicle-mounted air compressor and has an air inlet end and an air outlet end that are interconnected. The bottle cap is plugged into the air compressor body along a plugging direction through the air inlet end. The airflow from the air compressor body is suitable to pass through the air inlet end and the air outlet end in sequence.

In one embodiment of the present invention, the at least one assembly hole includes two assembly holes, which are arranged along an arrangement direction and are respectively located on opposite sides of the bottle cap, and the arrangement direction is perpendicular to the tightening direction.

In one embodiment of the present invention, the bottle cap member is suitable for being joined with a tire repair rubber container bottle along a joining direction, and the arrangement direction is perpendicular to the joining direction.

In one embodiment of the present invention, the bottle cap has at least one lug portion, and at least one assembly hole is located in at least one lug portion.

In one embodiment of the present invention, the bottle cap is suitable for engaging with a bottle mouth of a tire repairing rubber container bottle, and 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 air inlet direction of the air inlet end and the air outlet direction of the air outlet end are perpendicular to each other.

In one embodiment of the present invention, the air inlet direction of the air inlet end and the air outlet direction of the air outlet end are parallel to each other.

In one embodiment of the present invention, the air compressor body has a receiving recess and at least one locking hole, the bottle cap is received in the receiving recess, the at least one locking hole is located in the receiving recess, and at least one fastener is locked to the at least one locking hole.

In one embodiment of the present invention, the aforementioned receiving recess has at least one inner wall perpendicular to the fastening direction, and at least one locking hole is located on at least one inner wall.

In one embodiment of the present invention, the aforementioned receiving recess has an open end, and a locking tool is suitable for extending through the open end to at least one locking hole and locking at least one fastener to at least one locking hole.

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

Based on the above, the vehicle-mounted air compressor of the present invention uses a fastener to fasten the bottle cap to the air compressor body. The user only needs to simply install the bottle cap to the air compressor body and lock the fastener to complete the installation of the bottle cap, and the user only needs to simply remove the fastener and then remove the bottle cap to complete the removal of the bottle cap and/or the replacement of the tire repair rubber container.

FIG. 1 is a perspective view 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 perspective view 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 this embodiment includes an air compressor body 110, a bottle cap assembly 120 and an air outlet pipe 130. The bottle cap assembly 120 includes a bottle cap member 122 and a sealing 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 that are connected to each other. The air inlet 1221 and the air outlet 1222 are, for example, cylindrical bodies that protrude outward from the outer surface of the bottle cap 122. The air inlet direction of the air inlet 1221 and the air outlet direction of the air outlet 1222 are, for example, parallel to each other. The air inlet 1221 is suitable for being plugged into an air inlet pipe 112 of the air compressor body 110 along a plugging direction D1 (shown in FIG. 2). The sealing member 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 along a connecting direction D4 (shown in FIG. 2). The bottle cap 122 can be connected to the tire 60 through the air outlet pipe 130.

The high-pressure airflow from the air compressor body 110 is suitable for entering the bottle cap member 122 through the air inlet end 1221 of the bottle cap member 122, and reaching the tire repair rubber container bottle 50 through the bottle cap member 122, and then the high-pressure airflow drives the tire repair rubber in the tire repair rubber container bottle 50 to pass through the bottle cap member 122 and leave the bottle cap member 122 through the air outlet end 1222 of the bottle cap member 122 and flow to the tire 60 through the air outlet pipe 130, so as to achieve the effect of inflation and tire repair. 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.

The air compressor body 110 of this embodiment further includes at least one fastener 150 (two are shown). The fastener 150 fastens the bottle cap 122 to the air compressor body 110 along a fastening direction D2 (shown in FIG. 2 ), and the fastening direction D2 is the same as the plugging direction D1.

As described above, the vehicle-mounted air compressor 100 of the present embodiment uses the fastener 150 to fasten the bottle cap 122 to the air compressor body 110. The user only needs to simply install the bottle cap 122 to the air compressor body 110 and lock the fastener 150 to complete the installation of the bottle cap 122. The user only needs to simply remove the fastener 150 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 bottle 50. Furthermore, in this embodiment, the fastening direction D2 of the fastener 150 is set to be the same as the plugging direction D1 of the air inlet end 1221 of the bottle cap member 122, and the fastening position of the fastener 150 and the plugging 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), so that the user can plug the bottle cap member 122 and tighten the fastener 150 in sequence at the same position with a convenient and consistent 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.

FIG. 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 of the present embodiment has two lugs E and two assembly holes H1 respectively located at the two lugs E. The two fasteners 150 are, for example, screws, which pass through the two assembly holes H1 respectively and are locked to the air compressor body 110. Further, 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 at opposite sides of the bottle cap member 122, so that the fasteners 150 can securely fasten the bottle cap member 122.

Please refer to Figure 2. In this embodiment, the air compressor body 110 has a receiving recess 1101 and two locking holes H2. The receiving recess 1101 has an inner wall 1101a perpendicular to the fastening direction D2. The locking holes H2 are located on the inner wall 1101a and located in the receiving recess 1101. The bottle cap 122 is received in the receiving recess 1101, and the two fasteners 150 passing through the two assembly holes H1 are respectively locked to the two locking holes H2. Furthermore, the receiving recess 1101 has an open end 1101b, and a locking tool (such as a screwdriver) is suitable for extending through the open end 1101b to the locking hole H2 and locking the fastener 150 to the locking hole H2.

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 repair rubber container of Fig. 1. Referring to Fig. 5 and Fig. 6, the sealing member 124 of this embodiment is located in the bottle cap member 122 and surrounds the air inlet 122a. 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 member 124, so that the sealing member 124 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.

FIG7 shows a partial structure of the vehicle-mounted air compressor and the tire repairing rubber container bottle of FIG1. FIG8 shows a partial structure of the vehicle-mounted air compressor and the tire repairing rubber container bottle of FIG1. Referring to FIG7 and FIG8, specifically, the high-pressure airflow from the air compressor body 110 (shown in FIG1) can sequentially pass through the air inlet end 1221 and the air inlet 122a along the flow path P1 shown in FIG7 to reach the inside of the tire repairing rubber container bottle 50, and the tire repairing rubber inside the tire repairing rubber container bottle 50 can follow the high-pressure airflow and sequentially pass through the air outlet 122b and the air outlet end 1222 along the flow path P2 shown in FIG8 to flow to the tire 60 (shown in FIG3) through the air outlet pipe 130.

Please refer to FIG. 4 . In this embodiment, the bottle cap 122 has two cutting ribs 1224 . During the joining process between the tire repairing rubber container bottle 50 and the bottle cap 122 , the cutting ribs 1224 are suitable for cutting the sealing film on the bottle mouth 52 of the tire repairing rubber container bottle 50 , so that the bottle cap 122 is smoothly connected to the internal space of the tire repairing rubber container bottle 50 .

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

Fig. 9A to Fig. 9E are operation flow charts of the vehicle-mounted air compressor of Fig. 1. Fig. 10A to Fig. 10C are top views of the vehicle-mounted air compressor of Fig. 9A to Fig. 9C, respectively. First, as shown in Fig. 9A and Fig. 10A, the air outlet pipe 130 is sleeved on the air outlet end 1222 of the bottle cap 122, and a pipe clamp 160 is used to fasten the air outlet pipe 130 to the air outlet end 1222. Next, as shown in FIG9B and FIG10B, the bottle cap 122 is installed on the air compressor body 110 by the guidance 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 122 is plugged into the air inlet pipe 112 of the air compressor body 110, so that the air inlet pipe 112 is connected to the air inlet port 122a. The gap between the air inlet end 1221 and the air inlet pipe 112 can be sealed by a sealing ring 170 sleeved on the air inlet end 1221. In addition, there is an opening 110a on the top of the air compressor body 110. The connection between the air intake pipe 112 and the bottle cap 122 corresponds to the opening 110a as shown in FIG. 10B, so that the user can visually confirm whether the air intake pipe 112 and the bottle cap 122 are indeed connected through the opening 110a.

Then, as shown in FIG. 9C and FIG. 10C , the bottle cap 122 is fastened to the air compressor body 110 by the fastener 150 to form the state shown in FIG. 9D . Next, as shown in FIG. 9D to FIG. 9E , the bottle mouth 52 of the tire repairing rubber container bottle 50 is connected 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. 4 ) 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 inflation and tire repairing operation, 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 inflation and tire repairing operation. Finally, as shown in FIG. 3 , the air outlet pipe 130 is connected to the tire 60, and the tire 60 can be repaired and inflated by the vehicle-mounted air compressor 100.

FIG11 shows that the tire repairing rubber container bottle in FIG1 is replaced by a cover. FIG12 shows that the tire repairing rubber container bottle in FIG2 is replaced by a cover. FIG13A shows that the tire repairing rubber container bottle in FIG9D is replaced by a cover. FIG13B shows that the tire repairing rubber container bottle in FIG9E is replaced by a cover. The vehicle-mounted air compressor 100 of this embodiment may also only inflate the tire 60 without repairing the tire 60. Specifically, the tire repairing rubber container bottle 50 in FIG1, FIG2, FIG9D, and FIG9E may be replaced by the cover 70 in FIG11, FIG12, FIG13A, and FIG13B, and the rest of the operation process is the same as the above, and will not be described in detail here. Since the method shown in Figures 11, 12, 13A, and 13B 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 13B.

The following is a description of another embodiment of the vehicle-mounted air compressor 100' of the present invention. The main difference between the vehicle-mounted air compressor 100' and the aforementioned embodiment is that the air inlet direction and the air outlet direction of the bottle cap 122' of the vehicle-mounted air compressor 100' are perpendicular to each other, and the rest is similar or identical to the aforementioned embodiment. The specific description is as follows, wherein the same or similar components to the aforementioned embodiment are represented by the same or similar component symbols.

The bottle cap 122' can be connected to the tire 60 through the air outlet pipe 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 reaches the tire repair rubber container bottle 50 through the bottle cap 122', and then the high-pressure airflow drives the tire repair rubber in the tire repair rubber container bottle 50 to pass through 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 air outlet pipe 130, thereby achieving the effect of inflation and tire repair. 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.

The air compressor body 110' of this embodiment further includes at least one fastener 150 (shown as two). The fastener 150 fastens the bottle cap 122' to the air compressor body 110' along a fastening direction D2 (shown in FIG. 2), and the fastening direction D2 is the same as the plugging direction D1.

As described above, the vehicle-mounted air compressor 100' of the present embodiment uses the fastener 150 to fasten the bottle cap 122' to the air compressor body 110'. The user only needs to simply install the bottle cap 122' to the air compressor body 110' and lock the fastener 150 to complete the installation of the bottle cap 122'. The user only needs to simply remove the fastener 150 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 bottle 50. Furthermore, this embodiment sets the fastening direction D2 of the fastener 150 to be the same as the plugging direction D1 of the air inlet end 1221' of the bottle cap 122', so that the user can plug the bottle cap 122' and fasten the fastener 150 in sequence in a convenient and consistent working direction.

Fig. 24A to Fig. 24C are top views of the vehicle-mounted air compressor of Fig. 23A to Fig. 23C, respectively. First, after the air outlet pipe 130 (shown in Fig. 15) is installed on the bottle cap member 122', as shown in Fig. 23A (Fig. 24A) to Fig. 23B (Fig. 24B), the bottle cap member 122' is installed on the air compressor body 110' by the guidance 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 plugged into the air inlet pipe 112' of the air compressor body 110', so that the air inlet pipe 112' is connected to the air inlet port 122a'. The gap between the air inlet end 1221' and the air inlet 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'. The connection between the air inlet pipe 112' and the bottle cap 122' corresponds to the opening 110a' as shown in Figure 24B, so that the user can visually confirm whether the air inlet pipe 112' and the bottle cap 122' are indeed connected through the opening 110a'.

Then, as shown in FIG. 23C and FIG. 24C , the bottle cap member 122' is fastened to the air compressor body 110' by the fastener 150 to form the state shown in FIG. 23D . Next, as shown in FIG. 23D to FIG. 23E , the bottle mouth 52 of the tire repairing rubber container bottle 50 is connected 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. 18 ) 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 inflation and tire repairing operation, 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 inflation and tire repairing operation. Finally, as shown in FIG16 , the air outlet pipe 130 is connected to the tire 60, and the tire 60 can be repaired and inflated by the vehicle-mounted air compressor 100 '.

FIG25 shows that the tire-repairing rubber container bottle in FIG14 is replaced by a cover. FIG26 shows that the tire-repairing rubber container bottle in FIG15 is replaced by a cover. FIG27A shows that the tire-repairing rubber container bottle in FIG23D is replaced by a cover. FIG27B shows that the tire-repairing rubber container bottle in FIG23E is replaced by a cover. The vehicle-mounted air compressor 100' of this embodiment may also only inflate the tire 60 without repairing the tire 60. Specifically, the tire-repairing rubber container bottle 50 in FIG14, FIG15, FIG23D, and FIG23E may be replaced by the cover 70 in FIG25, FIG26, FIG27A, and FIG27B, and the rest of the operation process is the same as the above, and will not be described in detail here. Since the method shown in Figures 25, 26, 27A, and 27B 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 27B.

In summary, the vehicle-mounted air compressor of the present invention uses a fastener to fasten the bottle cap to the air compressor body. The user only needs to simply install the bottle cap to the air compressor body and lock the fastener to complete the installation of the bottle cap, and the user only needs to simply remove the fastener and then remove the bottle cap to complete the removal of the bottle cap and/or the replacement of the tire repair rubber container. Furthermore, the present invention sets the fastening direction of the fastener to be the same as the plugging direction of the air inlet end of the bottle cap, so that the user can plug the bottle cap and fasten the fastener in a convenient and consistent working direction. In addition, since the tightening direction of the fastener is the same as the plug-in direction of the air inlet end of the bottle cap, the air inlet end can be stably plugged into the air compressor body by tightening the fastener.
