Technical Field

[0001] This utility model relates to the field of garden hair dryers, and in particular to a low-noise dual-duct garden hair dryer. Background Technology

[0002] In garden maintenance and management, garden blowers are an important tool for cleaning up fallen leaves and debris. With the continuous increase in urban green areas and people's increasing requirements for the quality of garden environments, garden blowers are being used more and more frequently. When carrying out garden work in densely populated places such as parks, campuses, and scenic spots, the noise generated by the blowers has gradually attracted attention.

[0003] However, traditional garden hair dryers have many shortcomings in practical applications. On the one hand, the traditional hair dryer is not reasonably designed in terms of structure. The disassembly and installation of the air inlet filter is cumbersome. Most of them are bolted and require tools for disassembly and installation, which is not convenient and makes it inconvenient to clean or replace the filter. On the other hand, many traditional garden hair dryers are noisy. The high decibel sound they produce when working will cause significant noise pollution to the surrounding environment, disturb the normal life of nearby residents, and also affect the leisure experience of tourists in parks and scenic spots.

[0004] To address these issues, a low-noise dual-duct garden blower is proposed. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-2 This utility model provides an embodiment of a low-noise dual-duct garden hair dryer, including a body 1, which is the hair dryer body and has a built-in motor. When working, it will generate noise. An air outlet pipe 2 is installed at the front end of the body 1. The air outlet pipe 2 is a dual-duct type, which is existing technology and can be implemented by those skilled in the art. A handle 3 is fixedly connected to the upper surface of the body 1 for easy gripping. An air inlet pipe 4 for air intake is fixedly connected through the left surface of the body 1. A quick-release mechanism is provided on the left surface of the air inlet pipe 4 to facilitate the removal and installation of the filter 51. A noise reduction component is provided inside the body 1 to absorb the noise when the motor is working, thereby achieving a noise reduction function. The quick-release mechanism includes a positioning component and a disassembly component.

[0035] Reference Figures 4-6 The positioning component includes a filter screen 51, which filters dust and impurities. A rod 52 is fixedly connected to the right surface of the filter screen 51. A through groove 53 is opened on the inner surface of the air inlet pipe 4. The rod 52 fits into the through groove 53 and is inserted into the inner wall of the through groove 53. A block 54 is fixedly connected to the right surface of the filter screen 51. A slot 55 is opened on the inner surface of the air inlet pipe 4. The block 54 fits into the slot 55. A locking block 57 is elastically connected to the inner wall of the front side of the block 54 by a compression spring 56. The disassembly component includes a pull rod 61, which is slidably connected to the inner surface of the filter screen 51. A pull ring 62 is fixedly connected to the left surface of the pull rod 61. Fingers can be inserted into the pull ring 62 for easy pulling. A round rod 63 is fixedly connected to the right surface of the pull rod 61. A slanted groove 64 is opened on the inner surface of the locking block 57 and fits into the round rod 63 and the slanted groove 64.

[0036] Reference Figures 4-6 The through slot 53 is tapered with a larger opening on the left and a smaller opening on the right. During the insertion of the insert rod 52 into the through slot 53, the through slot 53 provides a guiding function. The insert block 54 is inserted into the inner wall of the slot 55, and the outer wall of the insert block 54 fits against the inner wall of the slot 55. The locking block 57 passes through and slides on the rear surface of the slot 55. The rear end of the right surface of the locking block 57 is set as a slope. When the insert block 54 and the slot 55 are inserted, the slope of the locking block 57 will be squeezed. The locking block 57 is locked on the right surface of the air inlet pipe 4, which can form a limit. The pull rod 61 passes through the left surface of the locking block 57. The round rod 63 slides on the inner wall of the inclined groove 64. The inclined groove 64 is inclined in the front right and rear left direction. When the round rod 63 moves to the left, it will squeeze the inner wall of the inclined groove 64, which will drive the locking block 57 to move forward and retract into the insert block 54, releasing the limit.

[0037] Reference Figures 1-3 The noise reduction component includes a circular tube 71, which is connected to the rear surface of the body 1. A one-way valve 72 is provided in the middle section of the circular tube 71. The one-way valve 72 is existing technology and can be implemented by those skilled in the art. A cavity 73 is provided on the inner surface of the body 1. External air can enter the cavity 73 through the circular tube 71, and the internal air cannot be discharged. Argon gas can be filled into the cavity 73 during use to achieve the noise reduction effect.

[0038] Working principle: When the device is in use, outside air enters through the air inlet pipe 4. The filter screen 51 at the left end of the air inlet pipe 4 can filter dust and impurities to ensure the cleanliness of the internal components. When the filter screen 51 is installed, the insertion rod 52 is inserted into the through groove 53. The through groove 53 can provide a guiding function to ensure that the insertion block 54 and the slot 55 are aligned.

[0039] When the insert 54 is inserted into the slot 55, the inclined surface of the locking block 57 will be squeezed, and the locking block 57 will retract into the insert 54 to release the obstruction. When it is inserted, under the action of the compression spring 56, the locking block 57 will be pushed out and locked onto the right surface of the air inlet pipe 4 to position the filter screen 51. When it is necessary to remove the filter screen 51, pull the pull ring 62 to drive the pull rod 61 and the round rod 63 to the left. The round rod 63 slides in the inclined groove 64, squeezing the inner wall of the inclined groove 64 to move the locking block 57 into the insert 54, releasing the limit, and the filter screen 51 can be easily removed for cleaning or replacement.

[0040] The motor inside the body 1 generates noise during operation. The noise reduction component comes into play. Before use, argon gas is filled into the cavity 73. Argon gas has good noise reduction properties and can absorb the noise generated by the motor, thereby reducing the overall noise emitted by the blower during operation. After the motor inside the body 1 starts, it generates power to draw air in through the air inlet pipe 4. After passing through the filtration and noise reduction process, the air is pressurized and accelerated, and then blown out through the front dual-air duct outlet pipe 2. The dual-air duct design makes the blown air more concentrated and powerful, which is convenient for cleaning leaves, debris, etc. during garden operations and improves work efficiency.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
