Description

Technical Field

[0001] The utility model relates to the technical field of water blowers, in particular to a silent and noise-reducing water blower for pets. Background Art

[0002] The structure of the noise reduction hair dryer for drying pet hair mainly includes the shell, motor, fan, heater, control panel and filter. The motor drives the fan to rotate, generating a strong airflow, which is sprayed out through the air outlet after heating to dry the pet's body and hair. The control panel is used to adjust the power, temperature and wind speed of the hair dryer, while the filter can effectively filter impurities in the air and keep the air flowing smoothly. In terms of noise reduction, a variety of noise reduction technologies are used, including shock-absorbing materials and noise reduction design, optimized airflow dynamic design and the application of sound insulation materials, so as to provide a relatively quiet environment for pets to feel comfortable during the drying process.

[0003] For example, a silent and noise-reducing water blower for pets disclosed in the authorization announcement number CN216874466U includes a shell, the shell includes an oscillating wind component, the oscillating wind component is arranged inside the shell, the oscillating wind component includes a hot air cylinder, a half gear and a rack, the half gear is arranged at one end of the hot air cylinder, the half gear and the rack are meshed with each other, and a rotating shaft is passed through the center of the half gear. When the device is started, the hot air cylinder generates hot air, and the hot air is blown out from the shell to dry the pet's hair. In addition, the oscillating wind component is started together, and it moves back and forth through the rack. The reciprocating motion causes the half gear to rotate back and forth, and the half gear drives the hot air cylinder to swing back and forth. However, in this technical solution, the swing assembly is located in the shell, and the half gear, rack and other components of the swing assembly are close to one side of the hot air source, while the hot air cylinder and the blowing port are farther away from the hot air source than the swing assembly, and the structural composition of the swing assembly itself hinders the normal blowing of hot air, that is, the hot air needs to pass between the structures of the swing assembly to reach the blowing port. Such a design causes part of the heat to be blocked or lost, affecting the effective use of hot air, thereby reducing the overall drying efficiency. Utility Model Content

An isolation disk 8 is installed at the other end of the water blower housing 1, and a PCB board 9 electrically connected to the input end of the worm gear drive unit 14 is installed on the outer wall of one side of the isolation disk 8. A control panel 5 is installed on one side of the top of the water blower housing 1, and the output end of the control panel 5 is electrically connected to the input end of the PCB board 9.

[0022] The worm gear drive unit 14 drives the rotating shaft 12 to rotate back and forth, so that the guide plate 13 swings, thereby adjusting the angle and direction of the air outlet;

[0023] A handle 4 is fixed to the top of the water blower housing 1, and a rectangular hollow groove is provided at the top of the handle 4, so that the user can hold the water blower housing 1 conveniently through the handle 4;

[0024] An electric heating module 6 is installed on the outer wall of the isolation plate 8 away from the PCB board 9, and an axial flow fan 7 is installed on the top of the electric heating module 6. The hot air generated by the electric heating module 6 and the axial flow fan 7 is blown into the venturi tube 10 and the guide ring 11. The venturi tube 10 is used to control the flow direction of the gas and blow it out of the outside of the water blower housing 1 through the guide plate 13 and the front duckbill air outlet 3;

[0025] The electric heating module 6 includes a plurality of equally spaced cage plates 601 fixed on the outer wall of one side of the isolation disk 8, and an electric heating wire 602 surrounded by the outer peripheral surfaces of the plurality of cage plates 601.

In this process, the hot air generated by the electric heating module 6 and the axial flow fan 7 is blown into the venturi tube 10 and the guide ring 11. The venturi tube 10 is used to control the direction of gas flow and blow it out of the water blower housing 1 through the guide plate 13 and the front duckbill air outlet 3. When the user needs to realize the reciprocating swing of the blowing direction, the user controls the control panel 5 again The motor in the worm gear drive unit 14 is turned on to work, and the PCB board 9 controls the rotation direction of the motor according to the input control signal, thereby realizing the forward and reverse rotation of the PCB board 9, that is, the worm gear drive unit 14 drives the rotating shaft 12 to rotate reciprocatingly, so that the guide plate 13 swings, and then adjusts the angle and direction of the air outlet.
