Description

Technical Field

[0001] This utility model relates to the field of turbine fan technology, and in particular to a turbine fan for fire protection breathing apparatus. Background Technology

[0002] Fire protective breathing apparatus is a device that protects the respiratory system. It is mainly used at rescue sites to protect the respiratory system of firefighters in special environments. Some fire protective breathing apparatus is equipped with a turbine fan to provide auxiliary breathing airflow to the user.

[0003] Most fire-fighting breathing apparatus turbine fans have their drive plates located inside the housing, which prevents the drive plates from dissipating heat effectively during operation. Especially when fire-fighting breathing apparatuses are in use, the drive plates are prone to spontaneous combustion if they get too hot, resulting in low safety. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fire protection breathing apparatus turbine fan.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fire-fighting protective breathing apparatus turbine fan includes a fan housing, the fan housing includes an upper housing, a lower housing is installed at the bottom of the upper housing, and a mounting seat is provided on the upper surface of the upper housing;

[0007] The mounting base has a motor mounting cavity in the middle, a through hole in the middle of the bottom wall of the motor mounting cavity, a driver mounting groove in the outer side of the motor mounting cavity, and a plurality of second mounting posts evenly arranged on the outer surface of the motor mounting cavity. The driver mounting groove has first mounting posts symmetrically arranged in the driver mounting groove.

[0008] Furthermore, in a preferred configuration, a motor assembly is installed within the motor mounting cavity, and a driver board is installed within the driver mounting slot.

[0009] Furthermore, in a preferred configuration, the motor mounting cavity is fitted with a top cover above the motor assembly.

[0010] Furthermore, in a preferred configuration, an impeller is installed inside the upper housing, and the impeller is connected to the motor assembly through a through hole.

[0011] In addition, a preferred structure is that a first air vent is provided in the middle of the lower outer shell, and a groove is provided on the side of the upper part of the lower outer shell.

[0012] In addition, a preferred structure is that a second air vent is provided on one side of the upper outer shell, and a sealing gasket is affixed to the bottom side of the upper outer shell.

[0013] The beneficial effects of this utility model are as follows: This utility model uses an installation base to install the driver board, and the driver installation slot can isolate the driver board and install it on the outside, so that it does not need to be installed inside the turbine fan housing. This ensures that the driver board can effectively dissipate heat. Such a driver board will not spontaneously combust due to the inability to dissipate heat inside the turbine fan, thereby improving the service life of the equipment and enhancing safety.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-8A fire-fighting protective breathing apparatus turbine fan, comprising a fan housing 1, characterized in that the fan housing 1 includes an upper housing 12, a lower housing 11 installed at the bottom of the upper housing 12, a mounting seat 13 provided on the upper surface of the upper housing 12, a motor mounting cavity 132 opened in the middle of the mounting seat 13, a through hole 133 opened in the middle of the bottom wall of the mounting seat 132, a driver mounting groove 131 opened on the outer side of the mounting seat 132, a plurality of second mounting posts 135 evenly arranged on the outer surface of the mounting seat 132, and first mounting posts 134 symmetrically arranged in the driver mounting groove 131, the first mounting posts 134 being used to install a driver plate 3.

[0025] The motor mounting cavity 132 houses the motor assembly 5, and the driver mounting slot 131 houses the driver board 3. The motor mounting cavity 132 is used to install the motor assembly 5 separately.

[0026] Furthermore, a top cover 2 is installed on the motor mounting cavity 132 above the motor assembly 5, and the top cover 2 can effectively cover the motor assembly 5.

[0027] Meanwhile, an impeller 4 is installed inside the upper housing 12. The impeller 4 is connected to the motor assembly 5 through the through hole 133. The impeller 4 is used to transmit compressed air.

[0028] In addition, a first air vent 111 is provided in the middle of the lower outer casing 11, and a groove 112 is provided on the side of the upper part of the lower outer casing 11. The groove 112 is used for the sealing gasket 122 to be fastened.

[0029] Meanwhile, a second air vent 121 is provided on one side of the upper outer shell 12, and a sealing gasket 122 is attached to the bottom side of the upper outer shell 12. The sealing gasket 122 is used to improve the sealing between the lower outer shell 11 and the upper outer shell 12.

[0030] In this embodiment, when assembling the turbine fan, the driver board 3 is installed separately in the driver mounting slot 131, so that it is installed on the outside and does not need to be installed inside the turbine fan housing, thus ensuring that the driver board 3 can effectively dissipate heat.

[0031] During operation, the driver board 3 drives the motor assembly 5 to rotate the impeller 4 inside the lower housing 12, thereby assisting in the pumping of compressed air.

[0032] In this utility model, the driver board 3 is installed by the mounting base 13. The driver mounting slot 131 can isolate the driver board 3 and install it on the outside, so that it does not need to be installed inside the turbine fan housing. This ensures that the driver board 3 can effectively dissipate heat. Such driver board 3 will not spontaneously combust due to lack of heat dissipation inside the turbine fan, thereby improving the service life of the equipment and enhancing safety.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
