Abstract

The utility model relates to an air inlet device in a gardening tool for cooling a motor, which comprises an air inlet A and an air inlet B, wherein, the air inlet A is arranged at the air inlet end of the motor; and the air inlet B is far away from the air inlet A, and the air inlet A is communicated with the air inlet B through an air feed device. The air inlets are not directly arranged on the air inlet end of the motor, and are far away from the air inlet end of the motor, so the air inlets are also far away from the region of a rotating blade, the blockage and entrance of grass scraps and dust are avoided, the safety and reliability of the motor are ensured, and the normal operation of the machine is further guaranteed.

Description

The air-intake device that is used for cooling motor in a kind of garden instrument

Technical field

The utility model relates to the garden instrument technical field, more particularly relates to be used in a kind of garden instrument the air-intake device of cooling motor.

Background technology

Grass rake mechine, hay mover and loosenning tiller are a kind of outdoor garden instruments, are mainly used in to cut the grass on a lawn or the whole soil of pine.It by the driven by motor on the machine harrow careless cutter, mow blade and the blade rotation of loosening the soil prune the lawn or loosen the soil.

Existing grass rake mechine, hay mover and loosenning tiller are used for that the air intake of cooling motor normally realizes by the air inlet that is distributed in the motor air intake, this air inlet is nearer apart from the blade that rotates, therefore it has a defective usually: blade rotation produces certain distinguished and admirable during machine works, cut grass bits and dust are partly flown upward, be easy to stop up air inlet and enter motor internal by air inlet, reduced the cooling air quantity of motor, and then influence the operate as normal of motor, easily cause burning of motor.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of air-intake device that can effectively prevent foreign object obstruction air inlet or enter motor internal by air inlet is provided at the prior art present situation, make motor have enough air quantity to obtain cooling, and guarantee the operate as normal of machine and the security reliability of motor.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this air-intake device mainly includes:

Air inlet A, described air inlet A is arranged on the air intake of motor;

Air inlet B, described air inlet B are away from above-mentioned air inlet A, and air inlet A communicates by a defeated wind apparatus with air inlet B.

The air-intake device of aforementioned structure, its air inlet B can be opened on the hollow handle of instrument, is made of a plurality of wind hole that is distributed on the handle; And described defeated wind apparatus can be made of handle, guide duct and electric machine support, wherein electric machine support contains the cavity that communicates with air inlet A, guide duct is connected handle and electric machine support, constitute the air intake passage that is communicated with air inlet A and air inlet B by handle, guide duct and electric machine support, the tail end of described handle is equipped with pipe close.

The air-intake device of aforementioned structure, its described defeated wind apparatus also can adopt the pattern of the defeated wind of flexible pipe, air inlet A is located on the motor case, defeated wind flexible pipe one end is connected on the air inlet A, the other end then can be fixed on the suitable position of instrument, on the handle as instrument, and dust cover is housed in the end of flexible pipe.

Compared with prior art, advantage of the present utility model is: because air inlet is not directly to be opened on the air intake of motor, and away from the air intake of motor, thereby also away from the zone of rotating blade, avoided the obstruction of careless bits and dust and entered, guarantee the security reliability of motor, and then guaranteed the operate as normal of machine.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment one: as shown in Figure 1 and Figure 2, air-intake device of the present utility model mainly is made of air inlet A, air inlet B and a defeated wind apparatus that is communicated with air inlet A and air inlet B, wherein air inlet A is opened on the air intake of motor 12, air inlet B is away from this air inlet A, be positioned on the handle 3 of machine, handle 3 is to be made by hollow steel tube, the upper end offers a plurality of wind hole 11 therein, air is promptly entered by this wind hole, the lower end of handle 3 is provided with the air port, tail end is used to stop air intake to flow out with pipe close 4 sealings, makes air intake enter motor internal along dedicated tunnel.

Defeated wind apparatus is to be made of electric machine support 1, guide duct 2 and handle 3 etc., and wherein electric machine support 1 is fixed on the air intake of motor 12, and it is a hollow structure, and its internal cavity and air inlet A connect.Guide duct 2 contains hollow cavity, by on the guide duct 5 and guide duct under 6 form, it is connected between handle 3 and the electric machine support 1, wherein the one end is connected with the air inlet of electric machine support 1, the other end is connected with the air port of handle 3 lower ends, and is fixed on the handle 3 by bolt 7, pressing plate 9, handle holder 8 and locking knob 10.The air inlet A that is communicated with on the motor and the air intake passage of the air inlet B on the handle have been constituted by described handle 3, guide duct 2 and electric machine support 1.

The operation principle of this device is as follows: when machine works, motor 12 runnings produce air draught, and this air draught will enter in the wind hole 11 of upper end from handle, enters motor internal by guide duct 2 and electric machine support 1 again, comes cooling motor.

This device is by reasonably design, both reached the purpose of cooling motor etc., do not influence the profile of complete machine simultaneously again.

Embodiment two: as shown in Figure 3-Figure 5, the defeated wind apparatus that present embodiment is communicated with air inlet A and air inlet B mainly is to adopt a defeated wind flexible pipe 14, air inlet A is located on the case 13 of motor, air inlet B is located on the flexible pipe 14, defeated wind flexible pipe 14 1 ends connect on the air inlet A, the other end is equipped with dust cover 15, and it can be fixed on the suitable position of machine, is fixed on the machine handle 3 as selecting.When machine run, wind directly enters from flexible pipe 14 like this, and A enters motor internal by motor case air inlet.Relative embodiment one structure of the air-intake device of present embodiment is more simple, and cooling motor be can reach too, grass bits and the obstruction of dust and the purpose that enters motor internal avoided, but from the appearance of the machine flexible pipe of how having seen the outside.
