[0002] If the dust and water suction machine wants to reduce the noise, it is necessary to block the air pump. After the air pump is blocked, the temperature of the air pump will increase during operation, resulting in rapid loss of the air pump and a shortened service life. The continuous working time should not be too long. Too high may change the electrical properties of the air pump motor, thereby increasing the risk of damage to the air pump
Existing vacuum and water suction machines mainly use passive heat dissipation to dissipate heat from the air pump motor, which is not conducive to the long-term operation of the vacuum and water suction machine. The complexity of the organization and the rising cost

Embodiment Construction
[0020] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0021] Such as Figure 1~5 The air pump motor active heat dissipation structure shown includes a machine head base 1 , an air pump 3 , an air pump gland 4 , a surface cover 5 and a top cover 6 which are installed sequentially from bottom to top.
[0022] The air pump 3 includes a motor 11 and a turbine 13 connected by a shaft, and the top of the motor 11 has a motor cooling air inlet 12 .
[0023] The central part of the nose base 1 is provided with a turbine bin 16, and the turbine air outlet 15 is arranged below the turbine bin 16. The turbine 13 is placed in the turbine bin 16, and the main air passage 9 is drawn out from the edge of the turbine bin 16 on the nose base 1. Attached to the outside of the main air duct 9, a secondary air duct 10 with a closed front end is set, and the tail sections of the main and secondary air ducts are...

The invention discloses an active heat radiation structure of an air pump motor, and relates to the field of water and dust collectors. The active heat radiation structure of the air pump motor comprises a head pedestal, an air pump, an air pump gland and a surface cover which are installed from down to up sequentially; the air pump comprises a motor and a turbine which are connected through a shaft; a turbine chamber is arranged in the center position of the head pedestal; a turbine suction opening is formed under the turbine chamber; the turbine is placed in the turbine chamber; a main air duct is led out from the edge of the turbine chamber on the head pedestal; a secondary air duct with the closed front end is arranged close to the outer side of the main air duct; the tail sections of the main air duct and the secondary air duct are converged and then extended out of the head pedestal. The active heat radiation structure solves the problem that the air pump which is closed in the water and dust collector is hard to radiate, and utilizes the principle that the jet stream has reduced pressure intensity to drive the air to flow through the housing and inside of the air pump, so as to actively radiate heat, allows the motor to work at lower temperature to prolong the service life of the motor, and prevents burnout of the motor due to ultrahigh temperature.
Description
technical field [0001] The invention relates to a dust and water suction machine, in particular to an air pump cooling structure. Background technique [0002] If the dust and water suction machine wants to reduce the noise, it is necessary to block the air pump. After the air pump is blocked, the temperature of the air pump will increase during operation, resulting in rapid loss of the air pump and a shortened service life. The continuous working time should not be too long. If it is too high, it may change the electrical properties of the air pump motor, thereby increasing the risk of damage to the air pump. Existing vacuum and water suction machines mainly use passive heat dissipation to dissipate heat from the air pump motor, which is not conducive to the long-term operation of the vacuum and water suction machine. The complexity of the organization increases the cost. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the pres...
