Description

Technical Field

[0001] This utility model relates to the field of power tool technology, specifically to a high-efficiency heat dissipation and dustproof protective cover for electric picks. Background Technology

[0002] An electric pick is a double-insulated handheld power tool powered by a single-phase series-wound motor. It is safe, reliable, efficient, and easy to operate. It is widely used in pipeline laying, machinery installation, water supply and drainage facility construction, interior decoration, port facility construction, and other construction projects. It is suitable for use with picks or other appropriate accessories, such as chisels and shovels, to break, level, excavate, groove, and cut concrete, masonry structures, and asphalt pavements.

[0003] For example, the national authorized patent announcement number CN209936837U discloses an electric hammer, including a housing, a cylinder box, and a quick clamp. The cylinder box and the quick clamp are respectively mounted on the housing. The key feature is that a cylinder is installed inside the cylinder box, and a striking cone is installed inside the cylinder. A striking cone washer is installed on the inner side of the cylinder box opposite the striking cone. A buffer pad is installed on the inner side of the cylinder box in close contact with the striking cone washer. A first conical surface structure is provided on the end face of the striking cone closest to the striking cone washer, and a second conical surface structure is provided on the inner ring of the striking cone washer closest to the striking cone. With this electric hammer, when the striking cone hits the striking cone washer, the striking cone can easily enter the inner ring of the striking cone washer, and the striking cone washer can hold the striking cone in place, preventing the striking cone from moving to the other side of the cylinder without external force, thus effectively avoiding the phenomenon of an empty cone.

[0004] However, the aforementioned electric hammer does not have the function of dissipating heat and cooling the piston chamber during operation. The piston chamber generates a lot of heat during operation due to the reciprocating motion of the piston. If heat cannot be dissipated in time, the temperature inside the chamber will continue to rise, which will cause changes in the gas expansion coefficient and make the pressure inside the cylinder unstable. This will directly affect the impact force and movement speed of the hammer, resulting in a decrease in the power of the electric hammer. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency heat dissipation and dustproof protective cover for electric picks, so as to solve the problem mentioned in the background art that the electric pick does not have the function of heat dissipation and cooling of the piston chamber during operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-efficiency heat dissipation and dustproof protective cover for an electric pick includes: multiple sets of insertion ports formed on the outer surface of the piston cylinder of the electric pick body; a heat-conducting cylinder is fitted on the outer surface of the piston cylinder; multiple sets of heat-conducting blocks are fixedly installed on the inner ring wall of the heat-conducting cylinder; the heat-conducting blocks are fitted into the insertion ports, thereby sealing the piston chamber of the piston cylinder; and a heat dissipation mechanism is fitted on the outer surface of the heat-conducting blocks.

[0008] Preferably, the outer surfaces of the piston cylinder and the heat dissipation mechanism are fitted with dust covers.

[0009] Preferably, the heat dissipation mechanism includes annular aluminum fins, which are fixedly connected to the outer surface of the heat-conducting cylinder. A first copper tube is inserted inside the annular aluminum fins, and the inlet and outlet of the first copper tube extend out from inside the dust cover.

[0010] Preferably, the inlet and outlet of the first copper pipe extending from the dust cover are connected to the second copper pipe respectively. Both sets of the second copper pipes are N-shaped and inserted into U-shaped aluminum fins. The U-shaped aluminum fins are fixedly installed in the embedded groove, which is opened at one end of the outer shell of the electric pick body.

[0011] Preferably, the other ends of the two sets of second copper pipes are respectively connected to the inlet and outlet of the water pump, and the water pump is fixedly installed in the embedded groove, so that the water pump can circulate the coolant into the first copper pipe and the second copper pipe and then extract it.

[0012] Preferably, a cooling fan is fixedly installed in the U-shaped groove of the U-shaped aluminum fin.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the design of the piston cylinder, heat-conducting cylinder, heat-conducting block, and heat dissipation mechanism, the electric hammer body reciprocates within the piston chamber of the piston cylinder during operation. The piston chamber is composed of the piston cylinder and the heat-conducting block of the heat-conducting cylinder. This allows the heat generated by the reciprocating motion of the piston to be directly transferred to the heat-conducting block. The heat-conducting block then transfers the heat to the heat dissipation mechanism fixedly connected to the outer surface through the heat-conducting cylinder. This direct and efficient heat conduction path reduces the accumulation of heat within the piston cylinder and allows for faster heat dissipation, effectively reducing the temperature of the piston cylinder and internal components. This ensures that the electric hammer body maintains good heat dissipation during long-term operation.

[0015] 2. Through the design of a water pump, cooling fan, annular aluminum fins, a first copper tube, U-shaped aluminum fins, and a second copper tube, the piston cylinder conducts heat to the heat-conducting block. The heat-conducting block then conducts heat through the heat-conducting cylinder to the annular aluminum fins fixedly connected to its outer surface. The first copper tube, containing coolant, is installed inside the annular aluminum fins. The annular aluminum fins then conduct heat to the coolant in the first copper tube. The coolant, having absorbed heat, is pumped from the first copper tube into the second copper tube via a connection to the second copper tube. The second copper tube is fitted inside the U-shaped aluminum fins, allowing the heat-absorbing coolant to enter and conduct heat to the... The U-shaped aluminum fins perform heat dissipation, while the rotating cooling fan inside the U-shaped aluminum fins accelerates heat loss and improves heat dissipation efficiency. After initial cooling, the coolant is pumped into another set of second copper pipes for further heat absorption and dissipation by the U-shaped aluminum fins. After this second heat absorption and cooling, the coolant enters the first copper pipe to absorb heat from the piston cylinder again. By circulating the coolant between the first and second copper pipes, the heat generated by the piston cylinder is continuously absorbed and carried away, forming an efficient heat dissipation cycle. This ensures the continuity and stability of heat dissipation, allowing the electric hammer to maintain a low temperature even under high load. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-2 As shown, this embodiment provides a high-efficiency heat dissipation and dustproof protective cover for electric picks, including: multiple sets of insertion ports 105 opened on the outer surface of the piston cylinder 102 of the electric pick body 1; a heat-conducting cylinder 103 is fitted on the outer surface of the piston cylinder 102; multiple sets of heat-conducting blocks 104 are fixedly installed on the inner ring wall of the heat-conducting cylinder 103; the heat-conducting blocks 104 are fitted into the insertion ports 105, thereby sealing the piston chamber of the piston cylinder 102; a heat dissipation mechanism 2 is fitted on the outer surface of the heat-conducting blocks 104; and a dustproof cover 3 is fitted on the outer surfaces of the piston cylinder 102 and the heat dissipation mechanism 2.

[0023] Through the design of piston cylinder 102, heat-conducting cylinder 103, heat-conducting block 104, and heat dissipation mechanism 2, the electric hammer body 1 reciprocates within the piston chamber of piston cylinder 102 during operation. The piston chamber of piston cylinder 102 is composed of piston cylinder 102 and heat-conducting block 104 of heat-conducting cylinder 103. This allows the heat generated by the reciprocating motion of the piston to be directly transferred to heat-conducting block 104. Heat-conducting block 104 can then transfer the heat to the heat dissipation mechanism 2 fixedly connected to its outer surface through heat-conducting cylinder 103 for heat dissipation. This direct and efficient heat conduction path reduces the accumulation of heat within piston cylinder 102 and allows for faster heat dissipation, effectively reducing the temperature of piston cylinder 102 and its internal components, ensuring that the electric hammer body 1 maintains good heat dissipation during long-term operation.

[0024] like Figures 3-4 As shown, the heat dissipation mechanism 2 includes a circular aluminum fin 203, which is fixedly connected to the outer surface of the heat conduction cylinder 103. A first copper tube 204 is installed inside the circular aluminum fin 203, and the inlet and outlet of the first copper tube 204 extend out from inside the dust cover 3.

[0025] The inlet and outlet of the first copper pipe 204, which extends through the dust cover 3, are connected to the second copper pipe 206. Both sets of second copper pipes 206 are N-shaped and inserted into the U-shaped aluminum fins 205. The U-shaped aluminum fins 205 are fixedly installed in the embedded groove 101, which is located at one end of the outer shell of the electric pick body 1.

[0026] The other ends of the two sets of second copper pipes 206 are connected to the inlet and outlet of the water pump 201, respectively. The water pump 201 is fixedly installed in the embedded groove 101, so that the water pump 201 can circulate the coolant into the first copper pipe 204 and the second copper pipe 206 and then extract it. A cooling fan 202 is fixedly installed in the U-shaped groove of the U-shaped aluminum fin 205.

[0027] Through the design of the water pump 201, cooling fan 202, annular aluminum fins 203, first copper pipe 204, U-shaped aluminum fins 205, and second copper pipe 206, the piston cylinder 102 conducts heat to the heat-conducting block 104, which in turn conducts heat through the heat-conducting cylinder 103 to the annular aluminum fins 203 fixedly connected to its outer surface. The first copper pipe 204, containing coolant, is installed inside the annular aluminum fins 203. The annular aluminum fins 203 then conduct heat to the coolant within the first copper pipe 204. The coolant, having absorbed heat, is then pumped from the first copper pipe 204 into the second copper pipe 206 by the water pump 201 through a connection with the second copper pipe 206. The second copper pipe 206 is fitted inside the U-shaped aluminum fins 205, thus facilitating the cooling of the absorbed heat. The coolant enters the second copper pipe 206 and conducts heat to the U-shaped aluminum fins 205 for heat dissipation. At the same time, the rotating cooling fan 202 inside the U-shaped aluminum fins 205 can accelerate heat loss and improve heat dissipation efficiency. After initial cooling, the coolant is pumped by the water pump 201 into another set of second copper pipes 206 to undergo heat absorption and heat dissipation again through the U-shaped aluminum fins 205. After the second heat absorption and cooling, the coolant enters the first copper pipe 204 to absorb heat from the piston cylinder 102 again. By circulating the coolant in the first copper pipe 204 and the second copper pipe 206, the heat generated by the piston cylinder 102 can be continuously absorbed and carried away, forming an efficient heat dissipation cycle. This ensures the continuity and stability of heat dissipation, ensuring that the electric hammer can maintain a low temperature even under high load.

[0028] Based on the above technical solution, the working steps of this solution are summarized as follows: During operation, the electric hammer body 1 reciprocates within the piston chamber of the piston cylinder 102. The piston chamber of the piston cylinder 102 is composed of the piston cylinder 102 and the heat-conducting block 104 of the heat-conducting cylinder 103. This allows the heat generated by the reciprocating motion of the piston to be directly transferred to the heat-conducting block 104. The heat-conducting block 104 then transfers the heat through the heat-conducting cylinder 103 to the annular aluminum fins 203 fixedly connected to its outer surface. A first copper tube 204 is installed inside the annular aluminum fins 203, and coolant is stored in the first copper tube 204. This allows the annular aluminum fins 203 to transfer heat to the coolant in the first copper tube 204. The coolant, after absorbing heat, then passes through a second copper tube... The connection of pipe 206 is pumped from the first copper pipe 204 into the second copper pipe 206 by the water pump 201. The second copper pipe 206 is fitted inside the U-shaped aluminum fins 205, which allows the heat-absorbing coolant to enter the second copper pipe 206 and conduct heat to the U-shaped aluminum fins 205 for heat dissipation. At the same time, the rotating cooling fan 202 inside the U-shaped aluminum fins 205 can accelerate the heat loss and improve the heat dissipation efficiency. After the initial cooling, the coolant is discharged again by the water pump 201 into another set of second copper pipes 206, where it undergoes heat absorption and heat dissipation again through the U-shaped aluminum fins 205. After the second heat absorption and cooling, the coolant enters the first copper pipe 204 again to absorb heat from the piston cylinder 102, ensuring that the electric hammer can maintain a low temperature even when working under high load.

[0029] In summary: By circulating the coolant in the first copper pipe 204 and the second copper pipe 206, the heat generated by the piston cylinder 102 can be continuously absorbed and carried away, forming an efficient heat dissipation cycle. This ensures the continuity and stability of heat dissipation, effectively reduces the temperature of the piston cylinder 102 and its internal components, and ensures that the electric hammer body 1 can maintain a good heat dissipation state during long-term operation.
