[0010] Beneficial effects: This blower noise reduction structure installs the blower in the accommodating cavity of the box and covers the inner wall of the box with sound-absorbing cotton. The sound-absorbing cotton effectively absorbs the noise generated when the blower is working, reducing the propagation and reflection of the noise. In addition, a muffler is set at the blower outlet pipe to further reduce the noise level and improve the comfort of the production environment. Since the blower generates a lot of heat during operation, a heat dissipation mechanism is set to effectively dissipate the heat of the blower to ensure its normal operation, thereby optimizing the noise reduction effect of the blower and improving its heat dissipation performance.

[0016] Beneficial effect: The air inlet, the first through hole and the second through hole are arranged on the same side of the box, which facilitates the arrangement of sound-absorbing cotton on the inner wall of the box and ensures that the sound-absorbing cotton can effectively avoid the air inlet, the first through hole and the second through hole.

[0017] In an optional embodiment, it also includes a temperature sensor and a controller electrically connected to the temperature sensor, wherein the temperature sensor is connected to the blower to detect the temperature of the blower and transmit the detected temperature to the controller, and the controller is suitable for being electrically connected to a display screen and displaying the detected temperature on the display screen.

[0018] Beneficial effect: By setting a temperature sensor connected to the blower, the temperature sensor monitors the working temperature of the blower in real time and transmits the detected temperature to the controller. The detected temperature is displayed on the display screen so that the staff can promptly find out whether the blower has overheating or abnormal temperature problems, which helps to give early warning and take corresponding measures to ensure the safe and stable operation of the equipment.

[0019] In an optional embodiment, a detection sensor is further included, which is electrically connected to the controller. The detection sensor is used to detect the operating status of the cooling fan and transmit the detected operating status information to the controller. The controller is suitable for being electrically connected to a display screen and displaying the detected operating status on the display screen.

[0020] Beneficial effect: The operating status of the cooling fan is monitored in real time by the detection sensor and the detected operating status information is transmitted to the controller. The detected operating status is displayed on the display screen to facilitate the staff to monitor whether the cooling fan is operating normally.

[0021] In an optional embodiment, the air inlet holes are arranged in multiple rows, and multiple air inlet holes are arranged at intervals in each row.

[0022] Beneficial effect: By arranging multiple rows of air inlet holes at intervals on the box body, air can enter the accommodating cavity more evenly, thereby improving the heat dissipation efficiency and avoiding the occurrence of local overheating in the accommodating cavity.

[0023] In an optional embodiment, the corners of the upper end surface of the box body are provided with lifting rings.

[0024] Beneficial effect: By setting a lifting ring at the corner of the upper end surface of the box, it is convenient to lift and install or carry the box. At the same time, the box can be firmly fixed in the required position through the lifting ring to avoid shaking or tilting of the box, thereby ensuring the safety and stability of the equipment.

[0039] In order to solve the above technical problems, the following Figures 1 to 3 , describing an embodiment of the utility model.

[0040] According to an embodiment of the present utility model, on the one hand, as Figures 1 to 3As shown, a blower noise reduction structure is provided, including a box body 1, sound-absorbing cotton 3, a muffler 4 and a heat dissipation mechanism 5.

[0044] Specifically, Figure 3 As shown, the heat dissipation mechanism 5 is arranged on the box body 1 for dissipating heat from the blower 2 .

[0045] This blower noise reduction structure installs the blower 2 in the accommodating cavity 101 of the box body 1, and covers the inner wall of the box body 1 with sound-absorbing cotton 3. The sound-absorbing cotton 3 effectively absorbs the noise generated by the blower 2 when it is working, reducing the propagation and reflection of the noise. In addition, a muffler 4 is provided at the air outlet pipe of the blower 2 to further reduce the noise level and improve the comfort of the production environment. Since the blower 2 generates a lot of heat during operation, a heat dissipation mechanism 5 is provided to effectively dissipate the heat of the blower 2 to ensure its normal operation, thereby optimizing the noise reduction effect of the blower 2 and improving its heat dissipation performance.

[0046] It should be noted that the sound-absorbing cotton 3 refers to a sound insulation material. By covering the sound-absorbing cotton 3 on the inner wall of the box body 1, the propagation and reflection of the sound of the blower 2 can be reduced. The sound-absorbing cotton 3 can be made of foam plastic, sound insulation blanket, etc. In the embodiment of the present application, the type of the sound-absorbing cotton 3 is not specifically limited.

The accommodating cavity 101 is connected with the outside of the box body 1 through the air suction hole 105 and the air inlet hole 106, and the heat dissipation fan 501 is arranged in the air suction hole 105.

[0051] By providing the air suction hole 105 and the air inlet hole 106 on the side wall of the box body 1 and installing the heat dissipation fan 501 in the air suction hole 105, the heat dissipation mechanism 5 realizes an effective heat dissipation function. The heat dissipation fan 501 discharges the hot air in the accommodating cavity 101 to the outside of the box body 1 through the air suction hole 105, and at the same time, the cold air outside the box body 1 enters the accommodating cavity 101 through the air inlet hole 106, forming a good heat exchange environment. In this way, the heat generated by the blower 2 during operation can be quickly and effectively processed by the heat dissipation mechanism 5, thereby improving the heat dissipation efficiency of the blower 2 and ensuring the normal operation of the blower 2.

[0052] Specifically, one cooling fan 501 may be provided on the air suction hole 105 of the box body 1 , or a plurality of cooling fans 501 may be provided. In the embodiment of the present application, the number of the cooling fans 501 is not specifically limited.

[0054] In one embodiment, in combination Figure 1 and Figure 3 As shown, the air suction hole 105 and the air inlet hole 106 are respectively disposed on opposite side walls of the box body 1 .

[0055] By arranging the air suction hole 105 and the air inlet hole 106 on opposite side walls, better air convection is formed in the accommodating cavity 101, so that hot air is quickly discharged from the air suction hole 105 and cold air enters through the air inlet hole 106, thereby improving air flow efficiency and effectively reducing the heat generated by the blower 2 when it is working.

[0056] In one embodiment, if Figure 1 As shown, the air inlet 106 , the first through hole 102 and the second through hole 103 are all arranged on the same side of the box body 1 .

[0059] By setting a temperature sensor connected to the blower 2, the temperature sensor monitors the working temperature of the blower 2 in real time and transmits the detected temperature to the controller. The detected temperature is displayed on the display screen so that the staff can promptly find out whether the blower 2 has problems such as overheating or temperature abnormalities, which helps to give early warning and take corresponding measures to ensure the safe and stable operation of the equipment.

[0060] Specifically, since the temperature of the fan blades of the blower 2 is higher than the temperature at other positions, the temperature will be transmitted to the motor housing of the blower 2. When the temperature of the motor housing is too high, the motor will be damaged. The temperature sensor can be set at the motor housing of the blower 2.

[0061] Specifically, the temperature sensor can be an existing temperature sensor, such as a thermistor, a thermocouple, a semiconductor temperature sensor, etc., as needed. In the embodiment of the present application, there is no specific restriction on the type of the temperature sensor.

[0062] Specifically, the controller may be an existing controller such as a PLC (programmable logic controller), a microcontroller or a computer control system. In the embodiments of the present application, the type of controller is not specifically limited.

[0064] The operating status of the cooling fan 501 is monitored in real time by the detection sensor and the detected operating status information is transmitted to the controller, and the detected operating status is displayed on the display screen to facilitate the staff to monitor whether the cooling fan 501 is operating normally.

[0065] Specifically, the detection sensor can monitor the operating status of the cooling fan 501 in real time, including the speed, start and stop status, etc. The detection sensor can select existing sensors according to actual needs, such as photoelectric sensors, current sensors or vibration sensors, etc. In the embodiment of the present application, the type of the detection sensor is not specifically limited.

[0066] In one embodiment, if Figure 1 As shown, the air inlet holes 106 are arranged in multiple rows, and multiple air inlet holes 106 are arranged at intervals in each row.

[0067] By arranging multiple rows of air inlet holes 106 at intervals on the box body 1 , air can enter the accommodating cavity 101 more evenly, thereby improving the heat dissipation efficiency and avoiding the occurrence of local overheating in the accommodating cavity 101 .

[0069] In one embodiment, if Figure 1 and Figure 3 As shown, the corners of the upper end surface of the box body 1 are provided with lifting rings 107.

[0070] By setting a lifting ring 107 at the corner of the upper end surface of the box body 1, it is convenient to lift and install or carry the box body 1. At the same time, the lifting ring 107 can firmly fix the box body 1 at a required position to prevent the box body 1 from shaking or tilting, thereby ensuring the safety and stability of the equipment.

[0071] In one embodiment, the connection between the air inlet pipe and the first through hole 102 is sealed, and the connection between the air outlet pipe and the second through hole 103 is sealed.

[0072] By sealing the connection between the first through hole and the second through hole, the connection between the box and the outside world can be effectively reduced, thereby significantly reducing the propagation of noise.

[0073] According to an embodiment of the present utility model, on the other hand, Figures 1 to 3 As shown, a blower device is also provided, including a blower 2 and a noise reduction component.

[0074] Specifically, Figure 2 As shown, the blower 2 is arranged in the accommodating chamber 101 .

[0075] This blower device installs the blower 2 in the accommodating cavity 101 of the box body 1, and absorbs the noise generated by the blower 2 when it is working through the sound-absorbing cotton 3 on the inner wall of the box body 1, thereby reducing the propagation of the noise. By arranging a muffler 4 at the air outlet pipe of the blower 2, the noise level is further reduced, thereby improving the comfort of the production environment.

[0076] Specifically, the drum machine can be detachably disposed in the accommodating cavity 101 by means of fasteners, and the drum machine can also be detachably disposed in the accommodating cavity 101 by means of a snap-fitting piece. In the embodiment of the present application, no specific limitation is imposed on the installation method of the drum machine.

[0077] Specifically, pressure relief valves (not shown in the figure) are provided on the air inlet pipe and the air outlet pipe of the blower 2.

[0078] By arranging pressure relief valves on the air inlet pipe and the air outlet pipe, excess gas can be automatically released when the internal pressure of the blower 2 exceeds the set value, thereby maintaining the internal pressure of the blower 2 within a safe range, maintaining the stability of the operation of the blower 2, and preventing the blower 2 from being damaged or an accident due to excessive pressure.
