Description

  The present invention provides a sealing agent for sealing a puncture hole of a punctured pneumatic tire into the pneumatic tire, and supplying compressed air into the pneumatic tire to increase the internal pressure of the pneumatic tire. The present invention relates to a pump-up device.

  By the way, a suitable repairing temperature condition (for example, −30 to 60 ° C., etc.) usually exists in a sealing agent for tire repair used in a sealing / pump-up device (including Patent Document 1). This type of sealant tends to increase in viscosity as the temperature decreases. As the viscosity increases, the difficulty of spreading the sealing agent when injected (supplied) into the tire also increases in proportion.

  On the other hand, since the sealing / pump-up device is used under various environmental temperatures, the temperature of the sealing agent in the container also depends on the environmental temperature of the device. For this reason, the amount of the sealing agent contained in the container is usually set to an amount that can be sufficiently spread in the tire even when the temperature of the sealing agent is the lower limit of the operating temperature condition (a state in which the sealing agent is difficult to spread). Yes.

  However, depending on the environmental temperature in which the sealing / pump-up device is used, the temperature of the sealing agent is higher than the lower limit value of the operating temperature conditions. Therefore, the amount of sealing agent required for the amount of sealing agent set at this lower limit value is required. More than that.

Then, the compressed air is supplied to the container by the compressed air supply means, and the sealing agent flowing out from the outlet of the container and the compressed air are supplied to the pneumatic tire via the gas-liquid supply pipe. That is, the sealing agent in which the increase in viscosity is suppressed with respect to the environmental temperature is supplied to the pneumatic tire. For this reason, the quantity of the sealing agent accommodated in a container can be decreased rather than the quantity of the sealing agent set with the lower limit of the conventional use temperature condition.

  In addition, after supplying a sealing agent and compressed air to the punctured pneumatic tire, the sealing agent is filled in the puncture hole by traveling a specified distance, and the puncture hole is closed.

As shown in FIG. 4A, a ridge 42A is formed at the upper end of the inner peripheral cylindrical portion 42 so as to narrow the diameter of the jig insertion hole 44. The protruding portion 42 </ b> A is caught by the bulging portion 63 </ b> A of the shaft portion 63 of the piercing member 62 loaded in the jig insertion hole 44 so that it does not come out upward. The piercing member 62 includes a substantially cylindrical shaft portion 63 inserted into the jig insertion hole 44 and a disk-shaped large-diameter portion 64 formed at the upper end portion of the shaft portion 63. The shaft portion 63 has a shape that swells in a direction in which the diameter of the intermediate portion between the upper end and the lower end increases, and this swelled portion is particularly defined as a bulging portion 63A. In addition, the shaft portion 63 is provided with a plurality of slits from the lower end toward the upper end and is divided in the circumferential direction so that the diameter can be changed. Here, by reducing the diameter of the lower end portion side of the shaft portion 63, the diameter of the bulging portion 63A is also reduced, so that the bulging portion 63A can get over the protruding portion 42A of the inner peripheral cylindrical portion 42. Become. The large diameter portion 64 is coaxial with the shaft portion 63 and has a larger diameter than the shaft portion 63. At the outer peripheral end of the upper surface of the large-diameter portion 64, a protruding blade portion 66 for making it easy to break through the aluminum seal 30 is formed continuously. When the shaft portion 63 of the piercing member 62 is loaded in the jig insertion hole 44, the blade portion 66 faces the front surface of the aluminum seal 30 and is slightly between the tip of the blade portion 66 and the aluminum seal 30. Is provided.

(Jig)
As shown in FIGS. 4B and 5, the jig 82 includes a rod-shaped insertion portion 84 to be inserted into the jig insertion hole 44 and a substantially rectangular base portion 86 formed at the base end portion of the insertion portion 84. I have. The insertion portion 84 is formed with a jig communication path 88 that extends from the distal end surface toward the base portion 86 and bends and extends toward the outer peripheral side at the intermediate portion. An annular communication groove 90 is formed on the outer peripheral surface of the insertion portion 84, and a jig communication path 88 is opened on the bottom surface of the communication groove 90.

  Further, on the outer peripheral surface of the insertion portion 84, insertion grooves are formed on the upper side and the lower side of the communication groove 90, and O-rings 96 are inserted into the pair of insertion grooves. Further, the insertion portion 84 has a distal end portion 85 that is tapered so that the distal end portion 85 can enter the inner peripheral side of the shaft portion 63 of the piercing member 62. Further, the length of the insertion portion 84 is slightly longer than the dimension from the lower end of the jig insertion hole 44 to the aluminum seal 30. Thus, when the entire insertion portion 84 of the jig 82 is inserted into the jig insertion hole 44, the punching member 62 is pushed out from the jig insertion hole 44 as shown in FIG. Enters the liquid container 18. In a state where the entire insertion portion 84 is inserted into the jig insertion hole 44, the communication groove 90 of the insertion portion 84 and the air supply port 58 of the throttle portion 56 are aligned along the axial direction. Thereby, the throttle portion 56 communicates with the jig communication path 88 of the jig 82 via the communication groove 90. The pair of O-rings 96 press the outer peripheral ends of the pair of O-rings 96 to the inner peripheral surface of the jig insertion hole 44 over the entire circumference in a state where the insertion portion 84 is inserted into the jig insertion hole 44. Thereby, in a state where the entire insertion portion 84 is inserted into the jig insertion hole 44, the jig insertion hole 44 is sealed by the insertion portion 84 and the pair of O-rings 96 on the upper side and the lower side of the throttle portion 56, respectively. It becomes.

  Although not shown in the drawing, the jig 82 includes a pair of first pieces extending in the same direction as the extending direction of the inserting portion 84 on both sides of the base portion 86 with the inserting portion 84 interposed therebetween, and having a height lower than that of the inserting portion 84. A claw portion is provided, and a pair of second claw portions having a height lower than that of the first claw portion is provided closer to the insertion portion 84 than the pair of first claw portions. A first hooking claw having a substantially triangular cross section that protrudes toward the insertion portion 84 is provided at the distal end of the first hooking portion. The surface of the first hooking claw on the base portion 86 side is parallel to the base portion 86. It is a flat surface. Further, a second hooking claw having a substantially triangular cross section that protrudes toward the first claw part is provided at the tip of the second claw part, and the surface of the second hooking claw on the base part 86 side is the base part. It is a flat surface parallel to 86. Further, both the first claw portion and the second claw portion can be elastically deformed. The first hooking claw of the first claw portion and the second hooking claw of the second claw portion are the respective hooking portions formed in the unit main body portion 34 when the insertion portion 84 is inserted into the jig insertion hole 44. (For example, the edge of a hole, a level | step difference part, etc.) are hooked. The first hooking claw of the first claw part is hooked to the hooking part before the second hooking claw of the second claw part, and the first hooking claw of the first claw part is hooked on the hooking part. In this case, the aluminum seal 30 is not pierced by the perforating member 62. When the second hooking claw of the second claw portion is caught by the hooking portion, the aluminum seal 30 is pierced by the perforating member 62. Thus, the positional relationship between each catching claw and the catching portion is adjusted so that the distal end portion 85 of the insertion portion 84 is inserted into the liquid agent container 18 (attachment state of the jig 82).

  Here, when the jig 82 is attached, the internal spaces of the pressure hose 50, the air supply pipe 52, the throttle portion 56, the communication groove 90, and the jig communication path 88 communicate with each other, and compressed air generated by the air compressor 160. Is supplied into the liquid container 18. Note that the air supply path 60 is constituted by these internal spaces.

  In addition, a jig storage portion (not shown) for storing a jig 82 to be described later is formed on the front side wall surface 11F of the main casing 11. In this jig storage section, the insertion section 84 of the jig 82 can be inserted and stored.

(Operation of sealing / pump-up device)
Next, an operation procedure for repairing the punctured tire 100 using the sealing device 10 according to the present embodiment will be described. Note that the manual 17 described above describes the operation procedure of the sealing device 10 and the precautions in letters and illustrations.

  First, when the tire 100 is punctured, the user takes the sealing device 10 out of the storage space of the vehicle, arranges it on the road surface in an inverted state, and puts the seal 39 attached to the bottom wall surface 11B. The jig insertion hole 44 is opened by peeling. Next, the user removes the jig 82 from the jig housing portion on the front side wall surface 11 </ b> F of the main body casing 11, and inserts the insertion portion 84 into the jig insertion hole 44. When the insertion portion 84 presses the piercing member 62, the shaft portion 63 changes in diameter (reduced diameter), and the bulging portion 63A gets over (passes) the protruding portion 42A. The piercing member 62 is pushed up by the distal end portion 85 of the insertion portion 84, and pierces the aluminum seal 30 with the blade portion 66 while facing the aluminum seal 30. Then, the piercing member 62 is pushed into the liquid container 18 and the second hooking claw is hooked on the hooking portion, so that the jig 82 is in the mounted state.

  After the attachment of the jig 82 to the injection unit 20 is completed, the sealing device 10 is arranged on the road surface so as to be in an upright state (see FIGS. 1 and 2). As a result, the sealing agent 32 flows out of the hole 31 formed in the aluminum seal 30 by its own weight into the pressurized liquid supply chamber 40.

  Next, the joint hose 78 is taken out from the groove 25 together with the valve adapter 80, and the valve adapter 80 is connected to the tire valve 102 of the tire 100 (see FIG. 3). Thereby, the pressurized liquid supply chamber 40 and the inside of the tire 100 communicate with each other through the joint hose 78.

  Next, the plug 15 is removed from the groove 21 and the power cable 14 is unwound from the cable winding portion. And plug 15 is inserted in the socket of the cigarette lighter installed in vehicles. Thereby, electric power can be supplied from the battery to the power supply circuit of the compressor unit 12.

  Next, after the vehicle engine is started, the power switch 13 is turned on to supply power to the drive motor 170 of the compressor unit 12. The drive motor 170 supplied with electric power rotates, and the rotational force is transmitted to the transmission shaft 176 via the transmission gear 175 engaged with the motor gear 174. The rotation of the transmission shaft 176 is transmitted to the piston rod 168 via the pin 180 of the disk member 178, and the piston rod 168 reciprocates the piston head 164 in the cylinder 162. The compressed air pressurized in the pressurizing chamber 161 by the reciprocating motion of the piston head 164 and discharged from the check valve 169 is supplied into the liquid container 18 through the air supply path 60 (see FIG. 5). When the compressed air is supplied into the liquid agent container 18, the compressed air floats above the sealing agent 32 in the liquid agent container 18 to form a space (air layer G) on the sealing agent 32 in the liquid agent container 18. . The sealing agent 32 pressurized by the air pressure from the air layer G is pushed out to the pressurized liquid supply chamber 40 through the hole 31 formed in the aluminum seal 30. The extruded sealing agent 32 is injected (supplied) from the pressurized liquid supply chamber 40 into the tire 100 through the joint hose 78.

  In addition, after all the sealing agent 32 in the liquid container 18 is discharged, the sealing agent 32 in the pressurized liquid supply chamber 40 is pressurized and supplied into the tire 100 through the joint hose 78. Thereafter, when all the sealing agent 32 is supplied from the pressurized liquid supply chamber 40 and the joint hose 78 to the tire 100, the compressed air is supplied to the tire 100 via the liquid agent container 18, the pressurized liquid supply chamber 40, and the joint hose 78. Injected (supplied).

  Next, when it is confirmed by the pressure gauge 16 that the internal pressure of the tire 100 has reached the specified pressure, the user turns off the power switch 13 to stop the compressor unit 12 and remove the valve adapter 80 from the tire valve 102. .

  The user travels preliminarily for a certain distance (for example, 10 km) using the tire 100 into which the sealing agent 32 has been injected within a certain time after the completion of the inflation of the tire 100. As a result, the sealing agent 32 is uniformly diffused inside the tire 100, and the sealing agent 32 is filled in the puncture hole, thereby closing the puncture hole.

  After the preliminary run is completed, the user re-measures the internal pressure of the tire 100, reconnects the valve adapter 80 of the joint hose 78 to the tire valve 102 as necessary, and restarts the compressor unit 12 to define the tire 100. Pressurize to internal pressure. Thereby, the puncture repair of the tire 100 is completed, and the tire 100 can be used to travel at a certain speed or less (for example, 80 km / h or less) within a certain distance range.

  In the sealing device 10, when generating compressed air, heat is generated by driving the drive motor 170 or pressurizing air by the air compressor 160. The generated heat (so-called waste heat) warms the surrounding air (in a broad sense, the air in the compressor casing 150). The heated air is caused to flow downward in the compressor casing 150 by the air flow generated by the rotation of the impeller 173 attached to one end of the motor rod 172 of the drive motor 170, and is provided on the lower side. It passes through the air duct 152 and the plate material 146 and is sent around the neck portion 26 of the liquid agent container 18. Accordingly, the space on the liquid agent container 18 side partitioned by the partition plate 140 in the main body casing 11 is heated, and the sealing agent 32 in the liquid agent container 18 is heated from the outside of the liquid agent container 18. That is, even if the environmental temperature to be used (outside air of the sealing device 10) is low, the sealing agent 32 in the liquid container 18 is heated by the waste heat of the drive motor 170 and the air compressor 160, so that the sealing against the environmental temperature is performed. An increase in the viscosity of the agent 32 is suppressed. For this reason, since the sealing agent 32 in which the increase in viscosity is suppressed with respect to the environmental temperature is supplied to the tire 100, the sealing agent 32 easily spreads in the tire 100. For example, the lower limit value of the operating temperature condition of the sealing agent 32 Thus, the amount of the sealing agent 32 accommodated in the liquid agent container 18 can be made smaller than the amount of the sealing agent 32 set in (1). Here, when the amount of the sealing agent 32 is reduced, the cost is reduced by an amount corresponding to the reduction of the sealing agent 32. Further, the weight of the sealing device 10 is reduced by the amount of the sealing agent 32 reduced. Furthermore, the liquid agent container 18 can be reduced in size by the amount of the sealing agent 32 reduced, that is, the entire sealing device 10 can be reduced in size. Furthermore, the time for supplying the sealing agent 32 to the tire 100 can be shortened by the amount of reducing the sealing agent 32.

Further, since the sealing agent 32 in the liquid agent container 18 is heated using the waste heat of the drive motor 170 and the air compressor 160 when generating the compressed air, it is not necessary to provide a new heat source or the like. As a result, the cost of the sealing device 10 can be suppressed.
Furthermore, in this embodiment, since the sealing agent in the container is heated with the air heated by the heat generated by the drive motor 170 and the air compressor 160, the liquid agent container 18 is heated as compared with the case where the liquid agent container 18 is directly heated. Never too much.

Further, since the impeller 173 is rotated by the drive motor 170, it is not necessary to provide new power to generate an air flow. As a result, the cost of the sealing device 10 can be suppressed.
Furthermore, since the air heated by the air flow generated by the rotation of the impeller 173 is sent to the liquid agent container 18, the temperature around the drive motor 170 and the air compressor 160 is lowered and the drive motor 170 and the air compressor 160 are cooled. Is done. As a result, the occurrence of problems with the drive motor 170 and the air compressor 160 is suppressed.

  Then, since the opening of the air duct 152 faces the neck portion 26, the heated air is sent to the neck portion 26 of the liquid agent container 18 through the air duct 152. Here, since the sealing agent 32 flowing out from the liquid container 18 always passes through the outlet 29 of the neck portion 26, the air heated to the neck portion 26 is sent to heat the periphery of the neck portion 26 and supplied to the tire 100. The sealing agent 32 can be efficiently heated. Further, since the neck portion 26 has a smaller diameter than the container main body portion 18A, it is easier for heat to pass to the center than the container main body portion 18A, and an increase in the viscosity of the sealing agent 32 supplied to the tire 100 can be suppressed uniformly. .

  In the first embodiment, waste heat of the drive motor 170 and the air compressor 160 is used. However, the present invention is not limited to this configuration, and is separately linked to the ON operation of the power switch 13. You may provide the heat_generation | fever part which energizes and heat-generates. For example, a nichrome wire heater may be provided, and the surrounding air may be heated when the power switch 13 is turned on, and the heated air may be sent to the liquid container 18 by the air flow generated by the impeller 173.

  In the first embodiment, the impeller 173 is rotated using the drive motor 170 as a drive source. However, the present invention is not limited to this configuration, and a motor other than the drive motor 170 is provided. The impeller 173 may be rotated by using as a drive source. Moreover, you may use the apparatus which produces an air flow newly instead of the impeller 173. FIG.

[Second Embodiment]
Next, a second embodiment of the sealing / pump-up device will be described. In addition, about the same member as 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. As shown in FIG. 8, in the sealing device 200 of the second embodiment, one end portion of a heat conducting plate 202 made of a metal material is wound around the outer wall surface of the cylinder 162, and the other end portion is around the neck portion 26 of the liquid agent container 18. It is wrapped around. The heat conductive plate 202 is preferably excellent in thermal conductivity, and for example, it is preferable to use copper, alumina, or the like among metal materials. In the present embodiment, a copper plate is used as the heat conductive plate 202. Although not shown in the present embodiment, the air duct 152 and the plate material 146 of the first embodiment are not provided, but the impeller 173 is attached to the other end of the motor rod 172. In the second embodiment, the slit 144 of the first embodiment is formed in the lower part of the opposite side wall (the side wall on the compressor unit 12 side) of the main body casing 11, and the air flow generated by the impeller 173 is a compressor. It flows from the slit 142 to the slit 144 through an opening formed in the lower part of the side wall on the unit 12 side. By doing in this way, the drive motor 170 can be cooled and the malfunction by high temperature can be suppressed.

  In the sealing device 200, the cylinder 162 becomes high temperature by pressurizing air when generating compressed air or by reciprocating the piston head 164 inside. The heat (waste heat) of the cylinder 162 is sent to the neck portion 26 of the liquid agent container 18 through the heat conduction plate 202. Thereby, the sealing agent 32 in the liquid agent container 18 is heated from the outside of the liquid agent container 18. That is, even if the environmental temperature to be used is low, the sealing agent 32 in the liquid container 18 is heated by the waste heat generated by the pressurization of air or the reciprocating motion of the piston head 164, and therefore the sealing agent against the environmental temperature. The viscosity increase of 32 is suppressed. For this reason, since the sealing agent 32 in which the increase in viscosity is suppressed with respect to the environmental temperature is supplied to the tire 100, the sealing agent 32 easily spreads in the tire 100. For example, the lower limit value of the operating temperature condition of the sealing agent 32 Thus, the amount of the sealing agent 32 accommodated in the liquid agent container 18 can be made smaller than the amount of the sealing agent 32 set in (1). The advantages when the amount of the sealing agent 32 is reduced are the same as in the first embodiment.

Further, since the sealing agent 32 in the liquid agent container 18 is heated using the waste heat generated by the pressurization of the air and the reciprocating motion of the piston head 164, it is not necessary to provide a new heat source or the like. As a result, the cost of the sealing device 200 can be suppressed.
Further, waste heat generated by air pressurization and reciprocating motion of the piston head 164 is directly conducted to the liquid agent container 18 via the heat conduction plate 202. Thereby, the sealing agent 32 in the liquid container 18 is efficiently heated.

  Since the other end portion of the heat conducting plate 202 is wound around the outer wall surface of the neck portion 26, the heat of the cylinder 162 is directly conducted to the neck portion 26 of the liquid container 18 through the heat conducting plate 202. Here, since the sealing agent 32 flowing out from the liquid agent container 18 always passes through the outlet 29 of the neck portion 26, the sealing agent 32 supplied to the tire 100 can be efficiently heated by directly conducting heat to the neck portion 26. Can do. Further, since the neck portion 26 has a smaller diameter than the container main body portion 18A, it is easier for heat to pass to the center than the container main body portion 18A, and an increase in the viscosity of the sealing agent 32 supplied to the tire 100 can be suppressed uniformly. .

  In the second embodiment, the other end of the heat conducting plate 202 is wound around the cylinder 162, and the sealing agent 32 in the liquid agent container 18 is heated by the heat of the cylinder 162. The other end portion of the heat conductive plate 202 may be wound around the main body portion 171 of the drive motor 170 or may be wound around both the cylinder 162 and the main body portion 171.

  In the second embodiment, the sealing agent 32 is heated using the heat of the cylinder 162. However, the present invention is not limited to this configuration, and the power switch 13 is turned on separately. It is also possible to provide a heat generating part that is energized in conjunction with the heat generating part and wraps the other end of the heat conducting plate 202 around the heat generating part and heats the sealing agent 32 using the heat of the heat generating part.

[Third embodiment]
Next, a third embodiment of the sealing / pump-up device will be described. In addition, about the same member as 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. As shown in FIG. 9, in the sealing device 210 of the third embodiment, an intermediate portion of the pressure hose 50 is fitted into a fitting groove 212 formed on the outer wall surface of the liquid agent container 18. The insertion groove 212 is formed in a spiral shape from the outer wall surface of the neck portion 26 of the liquid container 18 to the upper end of the liquid agent container 18, and the pressure hose 50 inserted into the insertion groove 212 has one end portion on the neck portion 26. The intermediate portion is wound around the container main body portion 18 </ b> A, and the other end portion extends to the air supply pipe 52. In addition, it is preferable that the pressure | voltage resistant hose 50 of this embodiment is formed with the material which can be heat-conductive. For example, iron, copper, aluminum, resin, rubber and the like can be mentioned. In the present embodiment, a rubber hose is used as the pressure hose 50. Although not shown in the present embodiment, the air duct 152 and the plate material 146 of the first embodiment are not provided, but the impeller 173 is attached to the other end of the motor rod 172. In the third embodiment, the slit 144 of the first embodiment is formed in the lower part of the side wall (the side wall on the compressor unit 12 side) opposite to the main body casing 11, and the air flow generated by the impeller 173 is a compressor. It flows from the slit 142 to the slit 144 through an opening formed in the lower part of the side wall on the unit 12 side. By doing in this way, the drive motor 170 can be cooled and the malfunction by high temperature can be suppressed.

  In the sealing device 210, the temperature of the air rises when the pressure is increased. Therefore, when the pressurized air (compressed air) passes through the pressure hose 50 wound around the outer wall surface of the container, the liquid container 18 is passed through the pressure hose 50. Heat is conducted to the inner sealing agent 32 and heated. That is, even if the environmental temperature to be used is low, the sealing agent 32 in the liquid container 18 is heated by the temperature increase of the air during pressurization. The For this reason, since the sealing agent 32 in which the increase in viscosity is suppressed with respect to the environmental temperature is supplied to the tire 100, the sealing agent 32 easily spreads in the tire 100. For example, the lower limit value of the operating temperature condition of the sealing agent 32 Thus, the amount of the sealing agent 32 accommodated in the liquid agent container 18 can be made smaller than the amount of the sealing agent 32 set in (1). The advantages when the amount of the sealing agent 32 is reduced are the same as in the first embodiment.

  Moreover, since the sealing agent 32 in the liquid agent container 18 is heated using the temperature rise of the air at the time of pressurization, it is not necessary to provide a new heat source. As a result, the cost of the sealing device 210 can be suppressed.

  Further, the pressure hose 50 is inserted into the insertion groove 212 provided on the outer wall surface of the liquid container 18, thereby increasing the contact area between the pressure hose 50 and the liquid container 18, and the heat of the compressed air passing through the pressure hose 50. Is efficiently conducted to the sealing agent 32 in the liquid container 18.

  And since the one end part side of the pressure hose 50 is wound around the outer wall surface of the neck part 26, since the compressed air whose temperature rose at the time of pressurization passes the one end side of the pressure hose 50 corresponding to the neck part 26 in the highest temperature state, the efficiency The neck portion 26 of the liquid container 18 can be warmed well. Here, since the sealing agent 32 flowing out from the liquid agent container 18 always passes through the outlet 29 of the neck portion 26, the sealing agent 32 supplied to the tire 100 can be efficiently heated by directly conducting heat to the neck portion 26. Can do. Further, since the neck portion 26 has a smaller diameter than the container main body portion 18A, it is easier for heat to pass to the center than the container main body portion 18A, and an increase in the viscosity of the sealing agent 32 supplied to the tire 100 can be suppressed uniformly. .

  In the above-described embodiment, the structure in which the sealing agent 32 in the liquid agent container 18 is heated using heated air as a medium, or one end portion of the heat conducting plate 202 is wound around the outer wall surface of the cylinder 162 and the other end portion is the liquid agent. A structure in which the sealing agent 32 in the liquid agent container 18 is heated by heat conduction by wrapping around the container 18 or an intermediate portion of the pressure hose 50 is inserted in the insertion groove 212 of the liquid agent container 18 to increase the temperature of the air when the pressure is increased. Although the configuration in which the sealing agent 32 in the liquid agent container 18 is heated with heat is used, the present invention is not limited to this configuration. For example, the liquid agent is used with a heating halogen lamp linked to the power switch 13 or the like. A configuration in which the sealing agent 32 in the container 18 is heated may be used.

  In the above-described embodiment, the reciprocating type air compressor 160 using the drive motor 170 as a drive source is used as the compressed air generation unit. However, the present invention is not limited to this configuration. A screw-type air compressor as a drive source may be used, or a scroll-type air compressor in which the drive motor 170 is driven down may be used.
