Description

Technical Field

[0001] The invention relates to an air compressor, in particular to a vehicle-mounted air compressor. Background Art

[0002] The vehicle-mounted air compressor can be used with a tire sealant container bottle to perform tire repair and inflation operations on the vehicle's tires, and can also be used to inflate the vehicle's tires without using a tire sealant container bottle. Generally speaking, when performing tire repair and inflation operations, a bottle cap assembly needs to be installed on the air compressor body of the vehicle-mounted air compressor to combine with the tire sealant container bottle, and the high-pressure airflow from the air compressor body passes through the bottle cap assembly and enters the tire sealant container bottle, and then the high-pressure airflow drives the tire sealant in the tire sealant container bottle into the tire, thereby achieving the effect of tire repair and inflation.

[0003] If the tire sealant in the tire sealant container accidentally flows through the bottle cap assembly into 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 sealant 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. Summary of the invention

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.

[0006] According to an embodiment of the present invention, a bottle cap assembly is suitable for a vehicle-mounted air compressor, and includes a bottle cap member and a sealing guide member.

[0035] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.

[0036] Figure 1 The present invention is a three-dimensional diagram of a vehicle-mounted air compressor and a tire repairing rubber container according to an embodiment of the present invention. Figure 2 yes Figure 1 Exploded view of the vehicle-mounted air compressor and tire sealant container. Figure 3 yes Figure 1 A three-dimensional diagram of a vehicle-mounted air compressor connected to a tire. Figures 1 to 3 The vehicle-mounted air compressor 100 of this 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 member 122 is mounted on the air compressor body 110 and has an air inlet end 1221 and an air outlet end 1222. The air inlet end 1221 and the air outlet end 1222 are, for example, both cylindrical bodies protruding outward from the outer surface of the bottle cap member 122. The air inlet end 1221 is suitable for being plugged into the air outlet pipe 112 of the air compressor body 110. The sealing guide member 124 is, for example, made of rubber, silicone or other types of elastic sealing materials and is disposed on the bottle cap member 122. The tire sealant container bottle 50 is used to be connected to the bottle cap member 122. The bottle cap member 122 can be connected to the tire 60 through the connecting pipe 130.

[0037] 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 sequentially passes through the bottle cap member 122 and the sealing guide member 124 to reach the tire sealant container bottle 50, and then the tire sealant in the tire sealant container bottle 50 is driven by the high-pressure airflow to sequentially pass through the sealing guide member 124 and 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 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 well known in the art and will not be elaborated here.

[0038] Figure 4 yes Figure 1 A partial stereoscopic view of a vehicle-mounted air compressor. Figure 5 yes Figure 1 Partial cross-section of the vehicle-mounted air compressor and tire sealant container. Figure 4 and Figure 5 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 in an integral form rather than being composed of a plurality of parts. When the bottle mouth 52 of the tire repair glue containing bottle 50 is engaged with the bottle cap member 122, the bottle mouth 52 of the tire repair glue containing 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 member 122 and the bottle mouth 52 of the tire repair glue containing bottle 50, thereby preventing the tire repair glue in the tire repair glue containing bottle 50 from flowing out through the gap between the bottle mouth 52 and the bottle cap member 122.

[0039] Figure 6 yes Figure 2 A three-dimensional view of the bottle cap and the sealing guide. Figure 7 yes Figure 6 A three-dimensional view of a bottle cap piece. Figure 8 yes Figure 6 Please refer to the three-dimensional image of the sealing guide. Figures 6 to 8 In detail, the bottle cap 122 of the present 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. Thus, 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. In addition, the 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 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 repair glue accommodating bottle 50 are connected as shown Figure 5 When the air inlet 1242a and the air outlet 1242b of the air guide 1242 are connected to the internal space of the tire sealant container 50. The high-pressure airflow from the air compressor body 110 is suitable for sequentially passing through the air inlet 122a, the air inlet 1242a, the internal space of the tire sealant container 50, the air outlet 1242b and the air outlet 122b.

[0040] Under the above configuration, the sealing guide 124 not only provides the existing sealing function by its sealing part 1241, but also covers the air inlet 122a of the bottle cap 122 by its guide part 1242. Accordingly, while the high-pressure airflow from the air compressor body 110 flows smoothly to the air outlet 122b of the bottle cap 122 through the guidance of the guide part 1242, the guide part 1242 can prevent the tire repair glue in the tire repair glue container bottle 50 from flowing to the air inlet 122a of the bottle cap 122. That is to say, in this embodiment, the guide part 1242 is integrally formed on the existing sealing member to cover the air inlet 122a of the bottle cap 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 prevent the tire repair glue from flowing to the air compressor body 110 through a simple structure, and the manufacturing and assembly difficulty of the bottle cap assembly 120 can be reduced.

[0041] Fig. 9 Show Figure 1 The local structure of a vehicle-mounted air compressor and a tire repair glue container bottle. Fig.10 Show Figure 1 The local structure of a vehicle-mounted air compressor and a tire repair glue container bottle. Fig.11 Show Figure 6 The partial structure of the bottle cap and sealing guide. Please refer to Figures 9 to 11 In more detail, the gap between the sealing guide member 124 and the bottle cap member 122 of this embodiment forms a guide channel 120a, and the guide channel 120a is connected between the air inlet 1242a and the air outlet 1242b. Figure 1 ) can flow along Fig. 9 The flow path P1 shown in FIG. 1 sequentially passes through the air inlet 1221, the air inlet 122a, the flow guide channel 120a and the air inlet hole 1242a to reach the inside of the tire repair glue container 50, and the tire repair glue 501 inside the tire repair glue container 50 can flow along the high pressure airflow. Fig.10 The flow path P2 shown in FIG. 1 passes through the air outlet hole 1242b, the air outlet port 122b and the air outlet end 1222 in sequence and flows through the connecting pipe 130 to the tire 60 (shown in FIG. 1 ). Figure 3 )flow.

[0042] Furthermore, the flow guide channel 120a is as follows Fig. 9 and Fig.10 As shown, the guide channel 120a extends in a zigzag manner, and the width of the guide channel 120a (i.e., the gap between the sealing 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. Accordingly, it can be ensured that the tire repairing glue with surface tension in the tire repairing glue containing bottle 50 will not flow to the air inlet 122a of the bottle cap member 122 through the guide channel 120a. The width of the guide channel 120a is, for example, 0.1 to 0.3 mm, but the present invention is not limited thereto.

[0043] Please refer to Figure 8 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 glue container 50 is connected to the glue bottle cover 122, the boss C protrudes into the tire repair glue container 50 and makes the air inlet 1242a definitely face the internal space of the tire repair glue container 50.

[0044] 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 edge ribs 1224. The two positioning ribs 1223 pass through the positioning slots 124a and the air outlet 1242b respectively, and the two cutting edge 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 repair glue container bottle 50 and the bottle cap member 122 are engaged with each other in a relatively rotating manner and in a screw cap manner, for example. When the tire repair glue container bottle 50 and the bottle cap member 122 rotate relative to each other during the engagement process, the positioning design of the positioning slots 124a and the positioning ribs 1223 can prevent the sealing guide member 124 from being twisted and deformed due to the rotation.

[0045] In addition, during the engagement process between the tire repairing rubber 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 bottle 50 , so that the sealing guide 124 can be smoothly connected to the internal space of the tire repairing rubber bottle 50 .

[0046] Please refer to Figure 2 and Figure 4 In the present embodiment, the vehicle-mounted air compressor 100 further includes a limit member 140 and at least one fastener 150 (two are shown). The limit member 140 limits the bottle cap member 122 to the air compressor body 110, and the fastener 150 is, for example, a screw and fastens the limit member 140 to the air compressor body 110. Accordingly, the user only needs to simply install the bottle cap member 122 to the air compressor body 110 and install the limit member 140 to complete the installation of the bottle cap member 122, and the user only needs to simply remove the limit 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 container bottle 50. Furthermore, the fastening direction of the fastener 150 is, for example, the same as the plug-in direction of the air inlet end 1221 of the bottle cap member 122 (such as Figure 2The vehicle-mounted air compressor 100 is conveniently assembled in 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 firmly plugged into the air compressor body 110 by fastening the fastener 150.

[0047] The operation flow of the vehicle-mounted air compressor of this embodiment is described below.

[0048] FIG. 12A to FIG. 12E yes Figure 1 Operation flow chart of vehicle-mounted air compressor. FIG. 13A to FIG. 13C They are FIG. 12A to FIG. 12C The top view of the vehicle-mounted air compressor. Fig. 12A and Fig.13A As shown, the connecting tube 130 is sleeved on the gas outlet end 1222 of the bottle cap 122, and the connecting tube 130 is fastened to the gas outlet end 1222 by using the tube clamp 160. Fig. 12B and Fig. 13B As shown, the bottle cap 122 is installed on the air compressor body 110 through the guidance of the two guide surfaces 116 of the air compressor body 110, and the bottle cap 122 is positioned by the two hooks 114 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 outlet pipe 112 of the air 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 surface of the air compressor body 110 has an opening 110a, and the connection between the air outlet pipe 112 and the bottle cap 122 is as shown in FIG. Fig. 13B The opening 110 a shown allows the user to visually confirm through the opening 110 a whether the air outlet pipe 112 and the bottle cap 122 are indeed connected.

[0049] Then, if Fig. 12C and Fig. 13C As shown, the stopper 140 is fastened to the air compressor body 110 by the fastener 150. Fig.12D In the state shown, the stopper 140 presses the bottle cap 122 against the compressor body 110 and the stopper 140 presses the connecting pipe 130. FIG. 12D to FIG. 12E As shown in FIG. 1 , the bottle mouth 52 of the tire sealant 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 edge rib 1224 (shown in FIG. 1 ) of the bottle cap 122. Figure 7) is cut, so that the high-pressure airflow from the air compressor body 110 can enter the tire sealant container 50 along the flow path P1 during the subsequent tire repair and inflation operations, and the tire sealant 501 in the tire sealant container 50 can leave the tire sealant container 50 along the flow path P2 during the subsequent tire repair and inflation operations. Figure 3 As shown, the connecting pipe 130 is connected to the tire 60 , and the tire 60 can be repaired and inflated by the vehicle-mounted air compressor 100 .

[0050] Fig.14 Show Figure 1 The tire sealant container bottle is replaced by a cover body. Fig.15 Show Figure 2 The tire sealant container bottle is replaced by a cover body. Fig.16A Show Fig.12D The tire sealant container bottle is replaced by a cover body. Fig. 16B Show Fig.12E The tire sealant container bottle in the embodiment 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, Figure 1 , Figure 2 , Fig.12D , Fig.12E The tire sealant container is 50 Fig.14 , Fig.15 , Fig.16A , Fig. 16B The cover 70 in the embodiment is replaced, and the rest of the operation process is the same as above, which will not be described in detail here. Fig.14 , Fig.15 , Fig.16A , Fig. 16B The method shown does not use the tire sealant container bottle 50, so the high-pressure airflow from the air compressor body 110 directly reaches the tire through the bottle cap assembly 120 to inflate the tire. Fig. 16B The flow path P3 is shown.

[0051] In summary, in the vehicle-mounted air compressor of the present invention, in addition to the existing sealing function provided by the sealing portion, the sealing guide member also covers the air inlet of the bottle cap member with its guide portion. Accordingly, while the high-pressure airflow from the air compressor body is guided by the guide portion and flows smoothly to the air outlet of the bottle cap member, the guide portion can prevent the tire repair rubber in the tire repair rubber container bottle from flowing to the air inlet of the bottle cap member. In other words, the present invention integrally forms a guide portion on the existing seal to cover the air inlet of the bottle cap member, so no additional parts are needed to achieve this purpose. Therefore, the vehicle-mounted air compressor and its bottle cap assembly of the present invention prevent the tire repair rubber from flowing to the air compressor body through a simple structure, and can reduce the difficulty of manufacturing and assembling the bottle cap assembly.
