Description
Technical Field
The utility model relates to a hot knife technical field, in particular to hand-held type hot knife.
Background
The hot cutter is a handheld cutter for realizing cutting by utilizing electric energy to generate heat, and is mainly divided into an electric heating wire type hot cutter and a resistance type hot cutter, wherein the electric heating wire type hot cutter is electrified by an electric heating wire to generate heat, and the resistance type hot cutter realizes the heating of a blade by introducing large current, the cost of the former is low, but the applicability of the former is poor, and the service efficiency of the latter is higher; when the power of the hot cutter is increased in the working process, the internal temperature is increased along with the increase of the power, if the heat is not dissipated in time, the service life of the hot cutter is seriously influenced for a long time, and particularly for cutting materials with high density and thickness, the power of the hot cutter required is higher, so that a heat dissipation fan needs to be installed; the mounted position of radiator fan and the design of wind gap position are not reasonable among the prior art, consequently the utility model develops a hand-held type hot knife to solve the problem that exists among the prior art, through the retrieval, not discover with the utility model discloses same or similar technical scheme.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is: the utility model provides a hand-held type hot knife to solve radiator fan's mounted position and the unreasonable problem of wind gap position design among the prior art.
The technical scheme of the utility model is that: a hand-held hot cutter comprises a shell, a transformation coil and a circuit board which are arranged in the shell, and a cooling fan which is arranged in the shell; the shell comprises a first shell and a second shell, the end parts of the first shell and the second shell are in nested fit, a first air inlet is formed in the side wall of the first shell, and a second air inlet is formed in the side wall of the second shell; the transformer coil is arranged in the first shell, and the circuit board is arranged in the second shell; the heat radiation fan is arranged at the joint of the first shell and the second shell, and a heat radiation port is arranged on the end face of the machine shell opposite to the heat radiation fan.
Preferably, the contained angle between the central axis of first casing and second casing is the obtuse angle, the one end that second casing and first casing are connected is the bending form to with first casing nested cooperation, radiator fan sets up inside the one end that the second casing is the bending form.
Preferably, the first air inlet is arranged on the opposite side wall of the first shell, and the second air inlet is arranged below one end, far away from the first shell, of the second shell.
Compared with the prior art, the utility model has the advantages that:
(1) because the transformer coil and the circuit board can generate heat in the working process of the hot cutter, the utility model arranges the heat radiation fan in the traditional structure at the connecting position of the first shell and the second shell, and when the heat radiation fan works, cold air can enter from the first air inlet and the second air inlet respectively and is used for radiating the transformer coil and the circuit board; meanwhile, the transformer coil generates larger heat, and the transformer coil is closer to the heat dissipation fan due to the fact that the length of the first shell is smaller than that of the second shell during structural design, so that the heat dissipation requirement can be fully met.
(2) First air intake setting not only can increase the area of air intake on the relative lateral wall of first casing, can also realize vary voltage coil's even cooling.
(3) Because the device is when using, need handheld second casing outer wall, for the entering of convenient cold wind, set up the second air intake in the one end below that first casing was kept away from to the second casing, when holding the second casing, can not influence cold wind and get into from the second air intake, cold wind gets into the back from the second air intake simultaneously, and the air current can be discharged from the thermovent through whole circuit board and final follow, and consequently the cooling effect of second air intake is also very good to the position design of circuit board.
Drawings
The invention will be further described with reference to the following drawings and examples:
fig. 1 is a schematic structural view of a hand-held hot knife according to the present invention;
fig. 2 is a front view of the internal structure of the hand-held hot knife of the present invention.
Wherein: 1. the heat dissipation device comprises a shell, 2, a transformation coil, 3, a circuit board, 4, a heat dissipation fan, 5, a first shell, 6, a second shell, 7, a first air inlet, 8, a second air inlet, 9 and a heat dissipation opening.
Detailed Description
The following detailed description is made in conjunction with specific embodiments of the present invention:
as shown in fig. 1 and 2, a handheld hot knife includes a housing 1, a transformer coil 2 and a circuit board 3 disposed in the housing 1, and a heat dissipation fan 4 installed in the housing 1.
The machine shell 1 comprises a first shell 5 and a second shell 6, the end parts of which are nested and matched, a first air inlet 7 is arranged on the side wall of the first shell 5, and a second air inlet 8 is arranged on the side wall of the second shell 6; the first air inlet 7 is formed in the opposite side wall of the first shell 5, so that the area of the air inlet can be increased, and the uniform cooling of the transformer coil 2 can be realized; the second air inlet 8 is formed in the lower portion of one end, far away from the first shell 5, of the second shell 6, so that cold air can enter conveniently, and the circuit board 3 can be cooled uniformly.
The transformer coil 2 is mounted in a first housing 5 and the circuit board 3 is mounted in a second housing 6.
The heat radiation fan 4 is arranged at the joint of the first shell 5 and the second shell 6, and a heat radiation port 9 is arranged on the end face of the machine shell 1 opposite to the heat radiation fan 4; in this embodiment, an included angle between central axes of the first casing 5 and the second casing 6 is an obtuse angle, one end of the second casing 6 connected to the first casing 5 is curved and is in nested fit with the first casing 5, the heat dissipation fan 4 is disposed inside the curved end of the second casing 6, and the heat dissipation port 9 is disposed on a side wall of an end portion of the second casing 6.
The utility model discloses in the course of the work, because transformer coil 2 and circuit board 3 all can generate heat, consequently open radiator fan 4 for cold wind gets into from first air intake 7 and second air intake 8 respectively, and cold wind cools down to it through transformer coil 2 and circuit board 3, and finally discharges from thermovent 9, and the work that the in-process passes through radiator fan 4 constantly inhales cold wind, effectively realizes the cooling of casing 1 inside.
