[0024] In the description of the present invention, it should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0025] like Figures 1 to 6 As shown, an embodiment of the utility model provides a detachable blower, the blower 100 includes a casing 10, a waterproof cover 20 and a motor 30, the casing 10 has an air inlet 11 and an air outlet 12, the air inlet 11 is arranged along a first direction X of the casing 10, and the air outlet 12 is arranged along a second direction Y of the casing 10; the waterproof cover 20 surrounds the outer periphery of the air inlet 11, and the waterproof cover 20 is detachably connected to the casing 10; the motor 30 is arranged inside the casing 10.

[0026] Based on the above technical solution, the blower 100 of this embodiment is an axial flow blower, the first direction X is the axial direction of the blower 100, and the second direction Y is the lateral direction of the blower 100. During installation, the housing 10 is first inserted into the installation hole of the inflatable toy, leaving only the air inlet 11 exposed, and then a waterproof cover 20 is used to surround the outer periphery of the air inlet 11 on the outside of the toy, and the waterproof cover 20 is fixed to the surface of the housing 10, thereby completing the assembly of the blower 100. During use, the motor 30 is directly started to draw air from the external environment into the housing 10 from the air inlet 11 of the housing 10, and then the air is discharged into the inflatable toy from the air outlet 12 of the housing 10, thereby completing the inflation process.

[0027] In this embodiment, the shapes of the waterproof cover 20 and the air inlet 11 are not specifically limited, and can be round, square, or other shapes, as long as the waterproof cover 20 surrounds the outer periphery of the air inlet 11 and can ensure that the air inlet 11 is effectively covered. The waterproof cover 20 prevents moisture, dust and other debris from entering the interior of the casing 10, protects the motor 30 or the circuit from damage, and ensures the operating stability and safety of the blower 100. It can be understood that the air inlet 11 is the position where moisture is most likely to enter the interior of the casing 10. Therefore, installing the waterproof cover 20 here can maximize its waterproof effect. Usually, the waterproof cover 20 is made of waterproof, corrosion-resistant and wear-resistant materials, such as waterproof cloth, rubber or plastic, which can effectively prevent moisture penetration while maintaining sufficient durability. Among them, the detachable connection between the waterproof cover 20 and the casing 10 allows the waterproof cover 20 to be easily cleaned, replaced or repaired.

[0028] In this embodiment, the motor 30 is arranged inside the housing 10, making the structure of the entire blower 100 more compact. At the same time, the protective function of the housing 10 can effectively prevent the external environment from interfering with or damaging the motor 30, thereby increasing the service life of the motor 30. Preferably, the PCB of the motor 30 is waterproofed by glue filling.

[0029] The main application scenario of the blower 100 of this embodiment is sustainable long-term operation in harsh environments such as low temperature and rain indoors and outdoors. The application industry is inflatable toy models, such as inflatable castles, inflatable slides, inflatable trampolines, etc. These toys need to be quickly inflated with the help of the blower 100 to save time and labor costs.

[0030] As an implementation method, Figure 2 and Figure 3 As shown, the air inlet 11 is circular, a first threaded portion 13 is provided on the outer periphery of the air inlet 11, and the waterproof cover 20 is provided with a second threaded portion 23, and the first threaded portion 13 is threadedly connected with the second threaded portion 23.

[0031] Specifically, the circular air inlet 11 cooperates with the first threaded portion 13 on its outer circumference to provide a clear and tight connection position for the waterproof cover 20. When the second threaded portion 23 of the waterproof cover 20 is threadedly connected with the first threaded portion 13 of the housing 10, the waterproof cover 20 and the housing 10 form a relatively sealed fan structure, thereby greatly improving the waterproof performance of the blower 100.

[0032] In the related art, the blower 100 is fixed to the inflatable toy by a cable tie, while in the present embodiment, the waterproof cover 20 is threadedly connected to the housing 10, which makes the installation and removal of the waterproof cover 20 very simple and quick. The waterproof cover 20 can be connected or separated from the air inlet 11 by simply rotating it, without the need for additional tools or complicated operations. Compared with the traditional cable tie fixing method, the knob fixing fabric is simpler, more convenient and easier to operate. During the operation of the blower 100, the connection between the waterproof cover 20 and the air inlet 11 needs to withstand certain vibrations and impacts. By threading the waterproof cover 20 to the housing 10, it can be ensured that the connection between the waterproof cover 20 and the air inlet 11 is stable and reliable, which can prevent vibrations and prevent the waterproof cover 20 from loosening or falling off.

[0033] It should be noted that the blower 100 can provide power to the motor 30 by installing a battery, or can provide power in the form of an external power cord 40.

[0034] As an implementation method, Figure 4 As shown, the blower 100 includes a power cord 40 and a nut 50. The housing 10 is provided with an output port 16. The output port 16 is integrally formed with the housing 10. The power cord 40 is plugged into the output port 16. The nut 50 is sleeved on the outer periphery of the power cord 40. The power cord 40 is fixed to the output port 16 through the nut 50.

[0035] In the related art, the housing 10 and the power cord 40 are connected by a traditional threading method. This connection method has poor waterproof performance. When the blower 100 is used outdoors, rainwater enters from the output port 16 of the housing 10 or from the power cord 40.

[0036] In this embodiment, the back of the housing 10 and the output port 16 are integrally formed, and the nut 50 is fixed with the output port 16 to ensure a stable connection between the power cord 40 and the housing 10. This integrated design of the housing 10 and the output port 16 enhances the sealing of the overall structure, reduces the risk of the power cord 40 falling off due to loosening or vibration during use, and improves the safety of the blower 100. The compression effect of the nut 50, on the one hand, makes the electrical contact between the power cord 40 and the output port 16 tighter, reducing electrical faults caused by poor contact, and on the other hand, it can prevent moisture from entering the interior of the housing 10 from the output port 16, further improving the waterproof performance of the blower 100.

[0037] As an implementation method, Figure 4 or Figure 5 As shown, the power cord 40 includes a connecting cable 43, a first charging cable 41 and a second charging cable 42. One end of the connecting cable 43 is connected to the adapter 60, and the other end of the connecting cable 43 is connected to the first charging cable 41 and the second charging cable 42. The first charging cable 41 is fixed to the output port 16 by a nut 50, and the second charging cable 42 is connected to the light string (not shown in the figure).

[0038] Specifically, the power cord 40 has a Y-shaped structure, and a connecting line 43 is divided into a first charging line 41 and a second charging line 42. The first charging line 41 is fixed to the output port 16 by a nut 50, and is fixed by rotating and tightening the nut 50 to improve the waterproof performance of the connection between the nut 50 and the output port 16. The second charging line 42 is connected to the light string, and the connection method with the light string is direct plug-in waterproof.

[0039] As an implementation method, Figure 5 As shown, the connection line 43 and the port of the adapter 60 are fixed together by a nut 50 .

[0040] Similarly, the connection line 43 is fixed to the port of the adapter 60 by rotating and tightening the nut 50. In this way, the blower 100 is connected to the power line 40 from the adapter 60, and then connected to the blower 100 and the light string to work, thereby increasing the waterproof function of the entire link from the overall structure, reducing the water leakage problem caused by the interface, realizing the standardization of scattered accessories, improving the service life of accessories and allowing them to be recycled repeatedly, improving the utilization rate of accessories, reducing user costs, and protecting the environment.

[0041] As an implementation method, Figure 6 As shown, the waterproof cover 20 includes a ring-shaped fixing portion 21 and a blade portion 22 disposed outside the fixing portion 21 , a second threaded portion 23 is disposed on the fixing portion 21 , and the blade portion 22 extends in a first direction X in a direction away from the housing 10 .

[0042] Specifically, the ring-shaped fixing portion 21 can better fit the circular air inlet 11, and cooperate with the tight connection between the first threaded portion 13 and the second threaded portion 23 to form a strong sealing structure, effectively preventing moisture from penetrating into the housing 10 through the air inlet 11. The blade portion 22 extends in a direction away from the housing 10, forming a barrier similar to a canopy, increasing the surface area of ​​the waterproof cover 20, and can more effectively guide water flow, helping to guide water droplets or water flow away from the housing 10, reducing the risk of moisture contacting the housing 10 or penetrating the air inlet 11.

[0043] As an implementation method, Figure 6 As shown, the blade portion 22 is in a semicircular arc shape.

[0044] Specifically, the semicircular shape of the blade portion 22 can effectively guide water droplets or water flow to slide down the blade surface, reducing the possibility of water droplets accumulating on the waterproof cover 20, thereby reducing the risk of moisture penetrating into the interior of the housing 10 through the waterproof cover 20. From the overall appearance, the semicircular blade portion 22 has smooth lines and an elegant shape, making the waterproof cover 20 more visually beautiful. Of course, the design of the blade portion 22 is relatively flexible and is not limited to a semicircular structure, and can be fine-tuned according to specific needs. For example, by adjusting the curvature or length of the blade, it can adapt to blowers 100 of different models and different usage environments.

[0045] As an implementation method, Figure 6 As shown, the blade portion 22 is integrally formed with the fixing portion 21. Since the blade portion 22 and the fixing portion 21 are integrally formed, the waterproof cover 20 is more stable in structure, and the risk of performance degradation or damage caused by loose or broken connections between components is reduced. The design of the blade portion 22 and the fixing portion 21 being integrally formed eliminates connectors or seams, thereby reducing potential leakage points and enhancing the waterproof performance of the waterproof cover 20.

[0046] As an implementation method, Figure 3 and Figure 6 As shown, the housing 10 includes a first shell 14 and a second shell 15 , the first shell 14 and the second shell 15 are detachably connected, the air inlet 11 is provided at the first shell 14 , and the air outlet 12 is provided at the connection between the first shell 14 and the second shell 15 .

[0047] Specifically, the motor 30 is installed in the cavity enclosed by the first shell 14 and the second shell 15 (i.e., inside the housing 10). Since the first shell 14 and the second shell 15 are detachably connected, when the motor 30 fails or needs to be repaired, the housing 10 can be easily disassembled, the motor can be taken out and repaired or replaced, thereby simplifying the repair process and improving the repair efficiency. Among them, the air inlet 11 is arranged on the first shell 14, i.e., in the axial direction of the blower 100, and the air outlet 12 is arranged at the connection between the first shell 14 and the second shell 15, i.e., in the lateral direction of the blower 100.

[0048] As an implementation method, Figure 2 and Figure 4 As shown, the first housing 14 and the second housing 15 are connected by screws and / or snaps.

[0049] Specifically, the first shell 14 and the second shell 15 can be connected by screws. By rotating the screws, they are tightly combined with the threaded holes to form a strong fixing force, ensuring a tight and stable connection between the first shell 14 and the second shell 15. This connection method enables the blower 100 to effectively resist external shocks and vibrations and improve the overall stability of the device. Of course, the first shell 14 and the second shell 15 can be connected by snap-fitting. The connection between the first shell 14 and the second shell 15 can be achieved through a simple snap-fitting action without the use of additional tools or equipment, which simplifies the installation and disassembly process and improves the installation and disassembly efficiency.
