[0002] An air compressor is a device used to compress and store gas. It increases the pressure of the gas by arranging the gas molecules tightly. This type of equipment is usually used in industrial production, the construction industry, and other occasions where large amounts of gas are required. Among them, air compressors in the construction industry can power tools such as rock drills, pneumatic picks, pneumatic wrenches, and pneumatic sandblasting.

[0003] Air compressors at construction sites usually need to work for long hours. In some areas with large temperature differences between day and night, the temperature is high at noon and low in the morning and evening. At noon, the air compressor's air tank temperature is very high and needs to be cooled. In the morning and evening, it is not necessary to cool the air tank. At noon, special personnel are required to cool the air tank, and the cooling time is uncertain, which wastes time and manpower. Summary of the invention

[0004] In view of the above-mentioned shortcomings, the present invention provides an air storage tank and an air compressor with automatic heat dissipation adjustment. The air storage tank can automatically cool down the air storage tank according to the temperature, saving manpower.

[0005] The first aspect of the present invention protects a gas storage tank with automatic heat dissipation adjustment, the gas storage tank comprising a tank body, a side wall of the tank body is provided with a plurality of arc-shaped pieces, and a connecting piece is provided between the arc-shaped piece and the tank body;

[0006] The two ends of the connecting piece are only fixed on the side walls of the tank body, and the middle part of the connecting piece is only fixed on the arc-shaped piece;

[0007] The connecting sheet is formed by combining two layers of metal sheets of different materials, wherein the expansion coefficient of the outer metal sheet is greater than the expansion coefficient of the inner metal sheet. When the temperature of the gas storage tank increases, the connecting sheet extends to form a gap between the arc-shaped sheet and the tank body.

[0008] Furthermore, the connecting piece includes a first connecting piece, a second connecting piece and a third connecting piece which are arranged in sequence in a vertical direction;

[0009] The inner metal sheets of the first connecting sheet, the second connecting sheet and the third connecting sheet are made of the same material;

[0010] The expansion coefficients of the outer metal sheets of the first connecting sheet, the second connecting sheet and the third connecting sheet decrease in sequence.

[0011] Furthermore, it also includes a drip assembly and a lifting member;

[0012] The liquid dripping component can drip liquid into the gap;

[0013] The lifting member can be raised and lowered according to the temperature. When the temperature rises, the lifting member rises, and when the temperature drops, the lifting member falls.

[0014] The lifting member rises to enable the dripping assembly to start dripping or increase the dripping amount, and the lifting member falls to enable the dripping assembly to reduce the dripping amount or stop dripping.

[0015] Furthermore, the drip assembly includes a liquid storage box and a water spray pipe connected to the liquid storage box;

[0016] The liquid storage box comprises a first groove, a second groove and a third groove which are arranged in sequence;

[0017] The first groove is filled with water, the third groove is filled with alcohol, and the water and the alcohol can be mixed in the second groove;

[0018] The water spray pipe is communicated with the second groove.

[0023] Furthermore, a spring is provided between the bottom end of the lifting rod and the column sleeve, and the material of the spring is a material with an expansion coefficient of 17×10 -6 / ℃ and above metals.

[0024] Furthermore, the top of the lifting rod is connected to the flow control rod.

[0025] A second aspect of the present invention protects an air compressor comprising the above-mentioned air storage tank with automatic heat dissipation regulation.

[0026] Beneficial effects: The present invention provides a connecting piece, in which the expansion coefficient of the outer metal is greater than that of the inner metal. When the temperature rises, the expansion area of ​​the outer metal is greater than that of the inner metal, so that the connecting piece changes from a flat plate to a curved shape, thereby causing a gap to be generated between the curved piece and the tank body, and the gap becomes larger as the temperature rises. The generation of the gap can increase the heat dissipation area of ​​the outer wall of the tank body and increase the heat dissipation; secondly, the air temperature at the top of the tank body is higher than that at the bottom, and when the hot air in the gap rises, it can pull the cold air at the bottom into the gap, effectively dissipating the heat from the tank body.

[0043] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In this application, the expansion coefficient of liquid refers to the volume expansion coefficient, and the expansion coefficient of metal refers to the thermal expansion coefficient.

[0045] refer to Figure 1 to Figure 9 The first aspect of the present invention protects a gas storage tank with automatic heat dissipation adjustment, which includes a tank body 11, and a plurality of arc-shaped pieces 13 are arranged on the outer side of the side wall of the tank body 11, and the arc of the arc-shaped piece 13 is the same as the arc of the side wall of the tank body 11, and the arc-shaped piece 13 can be completely attached to the side wall of the tank body 11, and the length of the arc-shaped piece 13 is close to the length of the side wall of the tank body 11. A connecting piece 12 is arranged between the arc-shaped piece 13 and the tank body 11. The connecting piece 12 is very thin and almost flat.

[0046] The two ends of the connecting piece 12 are only fixed on the side walls of the tank body 11, and the middle part of the connecting piece 12 is only fixed on the arc-shaped piece 13. The fixing method is bonding, welding and screw connection, etc., preferably screw connection.

[0047] The connecting piece 12 is formed by combining two layers of metal sheets of different materials, wherein the expansion coefficient of the outer metal sheet is greater than the expansion coefficient of the inner metal sheet. When the temperature of the gas storage tank increases, the connecting piece 12 extends to form a gap between the arc-shaped piece 13 and the tank body 11.

[0048] The present invention sets a connecting piece 12, and the expansion coefficient of the outer metal in the connecting piece 12 is greater than the expansion coefficient of the inner metal. After the temperature rises, the expansion area of ​​the outer metal is greater than the expansion area of ​​the inner metal, so that the connecting piece 12 changes from a flat plate to a curved shape, and then a gap is generated between the arc-shaped piece 13 and the tank body 11, and the gap becomes larger as the temperature rises. The generation of the gap can increase the heat dissipation area of ​​the outer wall of the tank body 11 and increase the heat dissipation; secondly, the air temperature at the top of the tank body 11 is higher than that at the bottom, and the hot air in the gap can pull the cold air at the bottom into the gap when it rises, effectively dissipating the heat of the tank body 11. The gas storage tank 1 of the present invention can automatically adjust the heat dissipation area according to the temperature, without manual intervention, saving manpower and time costs.

[0049] refer to Figure 5 In a specific embodiment, the connecting piece 12 includes a first connecting piece 121, a second connecting piece 122 and a third connecting piece 123 which are arranged in sequence in a vertical direction;

[0050] The inner metal sheets of the first connecting sheet 121 , the second connecting sheet 122 and the third connecting sheet 123 are made of the same material;

[0051] The expansion coefficients of the outer metal sheets of the first connecting sheet 121, the second connecting sheet 122 and the third connecting sheet 123 decrease in sequence. The first connecting sheet 121, the second connecting sheet 122 and the third connecting sheet 123 are completely the same in size and shape.

[0052] In this embodiment, by providing the first connecting piece 121, the second connecting piece 122 and the third connecting piece 123 with different expansion coefficients, the bending degree of the first connecting piece 121 is the largest after the temperature rises, and the bending degree of the third connecting piece 123 is the smallest. In this way, the gap at the top is larger than the gap at the bottom. The rising hot air at the top causes the cold air at the bottom to quickly enter the gap, and the fast flow of the cold air can hit the outer wall of the tank body 11 and the arc-shaped piece 13, effectively realizing heat exchange and cooling the tank body 11.

[0053] refer to Figures 1 to 9 , in a specific embodiment, it also includes a drip assembly 2 and a lifting member 5;

[0054] The dripping component 2 can drip liquid into the gap;

[0055] The lifting member 5 can be raised and lowered according to the temperature. When the temperature rises, the lifting member 5 rises, and when the temperature drops, the lifting member 5 falls.

[0056] The lifting member 5 rises to enable the dripping assembly 2 to start dripping or increase the dripping amount, and the lifting member 5 falls to enable the dripping assembly 2 to reduce the dripping amount or stop dripping.

[0057] In this embodiment, a lifting member 5 is provided, and the lifting member 5 can be raised or lowered synchronously according to the rise or fall of temperature, thereby controlling the dripping of liquid by the dripping assembly 2. Dropping liquid into the gap can reduce the amount of liquid used and increase the contact area between the liquid and the gas in the gap, thereby improving the heat dissipation effect. In addition, whether to drip liquid is automatically controlled according to the temperature, without manual control, saving manpower.

[0058] refer to Figures 7-9 In a specific embodiment, the drip assembly 2 includes a liquid storage box 21 and a water spraying pipe 22 connected to the liquid storage box 21. A water spraying pipe 22 is provided on each side, and the water spraying pipe 22 is arranged along the axial direction of the tank body 11, and a relatively fine water spraying hole is provided on the water spraying pipe 22.

[0059] The liquid storage box 21 is provided with a detachable top cover and a box body. Removing the top cover facilitates adding liquid into the box body. Figure 1 The top cover is provided with two openable exhaust holes to balance the pressure inside and outside the liquid storage box 21. The top cover can also be manually lifted to create a gap between the top cover and the box body to balance the pressure inside and outside the liquid storage box 21. The box body includes a first groove 211, a second groove 212 and a third groove 213 arranged in sequence;

[0060] The first groove 211 is filled with water, the third groove 213 is filled with alcohol, and the water and alcohol can be mixed in the second groove 212;

[0061] The watering pipe 22 is communicated with the second groove 212 .

[0062] The liquid storage box 21 in this embodiment is divided into three areas to store alcohol and water respectively. Water and alcohol are selected as cooling liquids because water has a large specific heat capacity and can absorb more heat, while alcohol is easy to evaporate and can also take away a lot of heat when evaporating. The combination of the two can effectively cool the tank body 11 and the arc-shaped sheet 13.

[0063] refer to Figures 7-9 In a specific embodiment, a water through hole 2111 is provided on the side wall of the first groove 211, so that water can flow into the second groove 212, and at least two alcohol through holes 2131 are vertically provided on the side wall of the third groove 213, so that alcohol can flow into the second groove 212. The number of the alcohol through holes 2131 can be a natural integer such as two, three, four, or five.

[0064] In this embodiment, there is only one water through hole 2111 on the side wall of the first groove 211, and at least two alcohol through holes 2131 are provided on the side wall of the third groove 213. Since water and alcohol are mixed in the second groove 212 to form a mixed liquid, such a setting can adjust the proportion of alcohol added. Figure 7As the flow control rod 55 rises, more and more of the alcohol through holes 2131 on the right side are connected with the second groove 212, so that more alcohol flows into the second groove 212, thereby increasing the proportion of alcohol in the mixed liquid and increasing the heat exchange rate.

[0065] refer to Fig. 9 In a specific embodiment, a mixed liquid through hole 2121 and a rod hole 2122 are provided at the bottom of the second groove 212 , and a flow control member is provided in the rod hole 2122 , and the flow control member can move in a vertical direction. The flow control member is a flow control rod 55 .

[0066] The second groove 212 in this embodiment is cylindrical, and a rod hole 2122 is provided in the middle of the bottom of the second groove 212, and the flow control rod 55 is placed in the rod hole 2122. A mixed liquid through hole 2121 is provided at the edge of the bottom of the second groove 212, and the mixed liquid through hole 2121 is connected to the water spray pipe 22 through a connecting pipe.

[0067] refer to Figures 1 to 4 In a specific embodiment, the lifting member 5 includes a lifting rod 51 and a column sleeve 52, and the bottom end of the lifting rod 51 is piston-shaped, which can increase the contact area with the regulating liquid;

[0068] The bottom end of the lifting rod 51 is arranged in the column sleeve 52. A regulating liquid is arranged between the bottom end of the lifting rod 51 and the column sleeve 52. The regulating liquid is a liquid with a large expansion coefficient. The expansion coefficient may be 0.75×10 -3 / ℃ alcohol or 0.9×10 -3 / ℃ kerosene.

[0069] refer to Figure 1 In this embodiment, four lifting members 5 are arranged on the top of the tank body 11, and the tops of the lifting rods 51 are connected by cross rods. By setting a liquid with a large expansion coefficient, the liquid expands when the temperature rises, and the lifting rods 51 can be lifted up, so that the lifting rods 51 rise. The lifting rods 51 can be automatically adjusted according to the temperature, without manual control, saving manpower.

[0070] refer to Figure 3 and 4 In a specific embodiment, a spring 53 is provided between the bottom end of the lifting rod 51 and the column sleeve 52. The material of the spring 53 is a material with an expansion coefficient of 17×10 -6 / ℃ and above metals.

[0071] The metal wire diameter of the spring 53 in this embodiment is small, and the deformation is large after being heated. The function of the spring 53 is to assist the regulating fluid. When heated, the spring 53 expands to provide an upward force, and the regulating fluid and the auxiliary sheet 54 jointly give the cross rod an upward force.

[0072] refer to Figure 5 and 6In a specific embodiment, the top of the lifting rod 51 is connected to the flow control rod 55. The top of the flow control rod 55 is piston-shaped. Preferably, the bottom of the flow control rod 55 is connected to the cross rod. The top side of the tank body 11 is also provided with a plurality of overlapping auxiliary sheets 54, each of which is also composed of two layers of metal sheets, and the expansion coefficient of the bottom metal is smaller than the expansion coefficient of the top metal. The thickness of each auxiliary sheet 54 is relatively thin.

[0073] In this embodiment, a plurality of auxiliary sheets 54 are provided. When the temperature is high, the deformation of each auxiliary sheet 54 can add an upward force to the cross bar, so that the flow control rod 55 can move upward. In addition, when the plurality of auxiliary sheets 54 are deformed, a large amount of space can be generated, which increases the heat dissipation area and can also help the tank body 11 to dissipate heat.

[0074] The metal in the connecting sheet 12 and the auxiliary sheet 54 of the present invention can be selected to have an expansion coefficient of 22×10 -6 / ℃ aluminum, 29.7×10 -6 / ℃ zinc, 17.2×10 -6 / ℃ copper and other materials.

[0075] refer to Figure 1 The second aspect of the present invention protects an air compressor, which includes the above-mentioned air storage tank. The top of the air storage tank 1 is also provided with a piston engine 3 and a motor 4. The air compressor with the air storage tank 1 has the function of automatically adjusting heat dissipation.

[0076] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
