Description

Technical Field

[0001] This utility model relates to the field of storm gun technology, and in particular to a storm gun that can be bidirectionally docked to change the blowing and suction mode. Background Technology

[0002] The Storm Gun is a multi-functional cleaning tool with strong airflow as its core advantage. It is widely used in various scenarios such as industrial production, home cleaning, and vehicle maintenance. Its core configuration consists of a high-power brushless motor and turbocharged fan blades, which can instantly release a strong airflow. The airflow can be several times stronger than that of a regular hair dryer, easily blowing away dust, debris, snow and other impurities.

[0003] However, existing equipment has the following shortcomings: The main body of the existing storm gun uses a short and straight nozzle design for both the suction and blowing ends, without an extendable airflow guiding structure. When used for floor cleaning or cleaning debris at a distance, the airflow from the short nozzle lacks effective restraint and spreads rapidly in all directions during propagation, failing to form a concentrated and sufficiently impactful airflow. The dispersed airflow is difficult to accurately target the debris (such as floor dust, debris in crevices, and distant accumulations), causing the debris to be unable to be blown away or gathered quickly. Some lightweight debris may even be blown into a wider area by the dispersed airflow, increasing the difficulty of cleaning. This design flaw requires users to repeatedly move the equipment and operate it at close range multiple times to complete the cleaning, which not only prolongs the operation time but also significantly reduces the overall cleaning efficiency. Especially in large-area cleaning or long-distance operation scenarios, it is difficult to meet the requirements of efficient and convenient use.

[0004] Therefore, we propose a storm gun that can be bidirectionally docked to change the blowing and suction method, in order to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the blower gun in the prior art has a fixed short nozzle design at the blowing and suction end, which makes the airflow easy to disperse and makes it difficult to accurately and quickly clean debris at a distance or in crevices, resulting in low cleaning efficiency. Therefore, this invention proposes a blower gun that can be bidirectionally connected to change the blowing and suction mode.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a storm gun capable of bidirectional docking and changing blowing and suction modes, comprising a main body, a handle, a battery box, a power motor, a fan, a connecting device, and auxiliary components. The handle is fixedly connected to the surface of the main body, the battery box is fixedly connected to the lower end of the handle, the power motor is fixedly connected inside the main body, the fan is installed at the output end of the power motor, the connecting device is installed at both ends of the main body, the connecting device includes a first connecting pipe and a second connecting pipe, the first connecting pipe is installed at the blowing end of the main body, the second connecting pipe is installed at the suction end of the main body, the auxiliary components are installed inside the second connecting pipe, the auxiliary components include a limiting groove and a limiting block, the limiting groove is opened at one end of the main body, the limiting block is fixedly connected to the end of the second connecting pipe near the main body, the limiting block is inserted into the limiting groove, an mounting ring is fixedly connected to the outer surface of the first connecting pipe, a first connecting plate is fixedly connected to the surface of the mounting ring, a second connecting plate is fixedly connected to the outer surface of the second connecting pipe, and a sliding groove is opened at the end of the second connecting plate near the first connecting plate.

[0007] Furthermore, a sliding rod is fixedly connected to one end of the first connecting plate near the second connecting plate. By setting the sliding rod, the first connecting plate and the second connecting plate can be connected, reducing the difficulty of horizontally installing the first connecting plate and the second connecting plate during use.

[0008] Furthermore, the slide rod is slidably connected inside the slide groove, and a slider is fixedly connected to the end of the slide rod away from the first connecting plate. The slider is provided to facilitate limiting the position of the slide rod.

[0009] Furthermore, the slider is slidably connected inside the groove, and a groove is provided at the end of the slider away from the first connecting plate.

[0010] Furthermore, a first spring is fixedly connected inside the groove, with the end of the first spring away from the groove fixedly connected inside the slide groove. The first spring is provided to facilitate the application of a restoring force to the slide rod.

[0011] Furthermore, a mounting groove is provided at one end of the second connecting pipe near the main body, and a rubber pad is fixedly installed inside the mounting groove to protect the connecting pipe.

[0012] Furthermore, the rubber pad is bonded to the surface of the main body.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a connecting device, the connecting pipe is effectively fixed, which extends the air blowing end of the main body. This reduces the problem that when the main body suction and blowing ends are relatively short, the air blown out by the blowing end is easy to disperse and difficult to move the debris on the ground or far away, resulting in low cleaning efficiency. This connecting device extends the air blowing end and improves the practicality of the equipment.

[0015] 2. In this utility model, by setting an auxiliary component, when the user installs the equipment, after the first connecting pipe and the second connecting pipe are sleeved and connected to both ends of the main body, the rubber pad protects the connecting pipe from the main body, reducing the hard contact between the connecting pipe and the main body and preventing damage from impact. This auxiliary component achieves buffer protection and air circuit sealing between the connecting pipe and the main body, avoiding damage from hard collisions between the connecting pipe and the main body, preventing air leakage from affecting the working effect, and extending the service life of the connecting pipe and the equipment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1-6 This utility model provides a technical solution: a storm gun that can be bidirectionally docked to change the blowing and suction mode, including a main body 1, a handle 2, a battery box 3, a power motor 4, a fan 5, a connecting device 6 and auxiliary components 7. The handle 2 is fixedly connected to the surface of the main body 1, the battery box 3 is fixedly connected to the lower end of the handle 2, the power motor 4 is fixedly connected to the inside of the main body 1, and the fan 5 is installed at the output end of the power motor 4.

[0026] The main body 1 is made of high-strength ABS engineering plastic through one-piece injection molding. It features an internal spiral air guide cavity that converges the airflow generated by the fan 5 into a high-speed airflow of up to 80m / s, reducing wind resistance loss. The outer wall has an anti-slip textured finish to improve grip stability. The main body 1 is the core airflow cavity of the storm gun. The grip 2 is an integral structure with the main body 1, conforming to ergonomic design. The grip area is covered with soft silicone, reducing fatigue during prolonged use. It integrates a control circuit board and start / stop switch, enabling stepless speed regulation of the motor 4. The battery box 3 is detachably connected to the grip 2 via a clip and is internally mounted... The 18650 lithium battery pack has a capacity of 2000mAh and supports fast charging. It can work continuously for 40 minutes on a full charge. The battery box 3 has a power indicator light on its surface for easy viewing of the remaining power. The power motor 4 is a brushless DC motor with a speed of up to 15000r / min and a power of 600W. Compared with a brushed motor, its lifespan is 3 times longer, and its operating noise is ≤65dB, making it suitable for quiet operation scenarios. The fan 5 is a centrifugal turbine fan with blades made of aviation aluminum alloy. It has undergone dynamic balancing treatment, so there is no vibration when rotating. It can efficiently convert electrical energy into wind energy, with a wind pressure of up to 10kPa.

[0027] The specific settings and functions of its connecting device 6 and auxiliary component 7 will be described in detail below.

[0028] In this implementation scheme: the connecting device 6 is installed at both ends of the main body 1. It is a key mechanism for realizing bidirectional docking and air path extension of the storm gun. It breaks through the limitation of the traditional storm gun's blow and suction ends being fixed and non-removable. Through the elastic locking structure of "slide rod 65-spring", it realizes the quick loading and unloading of the first and second connecting pipes with the main body 1. At the same time, it supports the series extension of multiple connecting pipes to expand the working range. The connecting device 6 includes a first connecting pipe 61 and a second connecting pipe 62. The first connecting pipe 61 is installed at the blow end of the main body 1, and the second connecting pipe 62 is installed at the suction end of the main body 1. The auxiliary component 7 is installed. Inside the second connecting pipe 62, the auxiliary component 7 includes a limiting groove 71 and a limiting block 72. The limiting groove 71 is opened at one end of the main body 1, and the limiting block 72 is fixedly connected to the end of the second connecting pipe 62 near the main body 1. The limiting block 72 is inserted into the limiting groove 71. The outer surface of the first connecting pipe 61 is fixedly connected to a mounting ring 610, and the surface of the mounting ring 610 is fixedly connected to a first connecting plate 63. The outer surface of the second connecting pipe 62 is fixedly connected to a second connecting plate 64, and the end of the second connecting plate 64 near the first connecting plate 63 is provided with a sliding groove 66.

[0029] Specifically, a slide rod 65 is fixedly connected to one end of the first connecting plate 63 near the second connecting plate 64. The slide rod 65 is a stainless steel optical shaft with chrome plating, straightness ≤0.02mm / m, and a clearance of ≤0.1mm between it and the slide groove 66 to ensure smooth sliding without jamming.

[0030] In this embodiment, by setting the slide bar 65, the first connecting plate 63 and the second connecting plate 64 can be connected, reducing the difficulty of horizontally installing the first connecting plate 63 and the second connecting plate 64 when the equipment is in use.

[0031] Specifically, the slide rod 65 is slidably connected inside the slide groove 66. A slider 67 is fixedly connected to the end of the slide rod 65 away from the first connecting plate 63. The slider 67 has a square structure and its size is larger than the opening width of the slide groove 66. It can effectively limit the sliding stroke of the slide rod 65 and prevent the slide rod 65 from coming out of the slide groove 66. The slider 67 is set to facilitate the limiting of the slide rod 65.

[0032] Specifically, the slider 67 is slidably connected inside the groove 66, and the end of the slide rod 65 away from the first connecting plate 63 has a groove 68.

[0033] Specifically, a first spring 69 is fixedly connected inside the groove 68. The first spring 69 is a tension spring, which keeps the first and second connecting plates in a closed state under natural conditions, ensuring that the connecting tube is tightly fitted with the main body 1. The spring force is optimized to 10-15N, which ensures both a stable connection and easy manual separation. The end of the first spring 69 away from the groove 68 is fixedly connected inside the slide groove 66. The first spring 69 is set to facilitate the application of a reset spring force to the slide rod 65.

[0034] In this embodiment: The second connecting pipe 62 has an installation groove 74 at one end near the main body 1. A rubber pad 73 is fixedly installed inside the installation groove 74. The rubber pad 73 is made of oil-resistant nitrile rubber with a Shore hardness of 50-60HA. It can both buffer and seal the air passage to prevent air leakage. The rubber pad 73 is set to protect the connecting pipe.

[0035] Specifically, the rubber pad 73 is attached to the surface of the main body 1.

[0036] Working principle: When using the device, the user installs the battery box 3 at the lower end of the handle 2, then presses the switch on the handle 2 to start the power motor 4 inside the main body 1. The power motor 4 then drives the fan 5 to rotate and blow air. Before using the device, the user holds the second connecting tube 62 and pulls the first connecting tube 61 and the first connecting plate 63 to move the slide rod 65 inside the second connecting plate 64. When the slide rod 65 moves, it stretches the first spring 69, generating elastic force. After installing the first connecting tube 61 and the second connecting tube 62 at both ends of the main body 1, the limiting block 72 inside the second connecting tube 62 is inserted. After being connected inside the limiting groove 71, the first connecting pipe 61 is released from its restraint. Then, the first spring 69 returns to its original position, causing the slide rod 65 to move inside the second connecting plate 64. This tightly connects the first connecting pipe 61 and the second connecting pipe 62 to both ends of the main body 1. By setting the connecting device 6, the connecting pipes are effectively fixed, which extends the air blowing end of the main body 1. This reduces the problem that when the existing equipment is in use, the air blowing end of the main body 1 is relatively short, and the air blown out from the air blowing end is easy to disperse and difficult to move the debris on the ground or far away, resulting in low cleaning efficiency. This connecting device 6 extends the air blowing end and improves the practicality of the equipment.

[0037] By setting auxiliary component 7, during equipment installation, after the user attaches the first connecting pipe 61 and the second connecting pipe 62 to both ends of the main body 1, the rubber pad 73 protects the connection pipe from damage caused by hard contact between the connection pipe and the main body 1. This auxiliary component 7 provides buffer protection and air circuit sealing between the connection pipe and the main body 1, preventing damage from hard collisions and air leakage that could affect the work performance, while also extending the service life of the connection pipe and the equipment.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
