The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0031] refer to Figure 1-3 The present application discloses a dual-purpose blowing and suction device, including a shell assembly 1, a fan 4 connected to the inner cavity of the shell assembly 1, a power supply 6 connected to the inner cavity of the shell assembly 1, a control assembly 5 connected to the inner cavity of the shell assembly 1 and used for electrically connecting to the fan 4 and the power supply 6, a blowing member 3 connected to the outer wall of one end of the shell assembly 1 and a suction member 2 connected to the outer wall of the other end of the shell assembly 1, the blowing member 3 forms a blowing channel 35 connected to the blowing end of the fan 4, the suction member 2 forms a suction channel 22 connected to the suction end of the fan 4, the shell assembly 1 has a dust storage chamber 127 located between the suction member 2 and the fan 4, for storing debris sucked from the suction channel 22.

[0032] The blowing and suction dual-purpose device involved in the present application has air intake and blowing formed at both ends of the fan 4 respectively. The air intake causes the wind flow to be sucked in from the suction channel 22 of the suction part 2, and then blown out from the other side of the fan 4. The wind flow formed by the blowing is blown out from the blowing channel 35, wherein the wind flow sucked in by the suction channel 22 sucks external debris (including dust, small particles, etc.) into the dust storage chamber 127 for storage, and the objects can be cleaned, and the air flow blown out from the blowing channel 35 can be used to inflate balloons, swimming rings, tires, etc., and in some cases, can also be used to clean dust, etc. In this way, the blowing and suction dual-purpose device can realize both blowing and suction, thereby increasing the function of the blowing and suction dual-purpose device and expanding the scope of application.

[0033] The fan 4 is a prior art and will not be described in detail in this application; both ends of the fan 4 are connected to the blowing channel 35 and the suction channel 22 respectively to achieve a connected circulation of the airflow and the outside air.

[0034] refer to Figure 1-3 and Figure 6-7The housing assembly 1 includes a first housing 11, a second housing 12 connected to one end of the first housing 11, and an inner housing 13 connected to the inner cavity wall of the first housing 11. The second housing 12 and the first housing 11 form a dust storage cavity 127. The blowing member 3 is connected to one end of the first housing 11 away from the second housing 12, and the blowing channel 35 is connected to the inner cavity of the inner housing 13. The blowing end of the fan 4 is connected to one end of the inner housing 13 away from the blowing member 3 and is connected to the inner cavity of the inner housing 13. The suction end of the fan 4 is connected to the second housing 12 and is connected to the dust storage cavity 127. The suction member 2 is connected to one end of the second housing 12 away from the first housing 11. The source device 6 is connected to the inner cavity wall of the inner shell 13, the control component 5 is connected between the first outer shell 11 and the inner shell 13, and the control button 51 of the control component 5 extends to the outer wall of the first outer shell 11. The control button 51 is pressed to control the opening and closing of the fan 4 through the integrated circuit of the control component 5. When the fan 4 rotates, the external airflow enters the dust storage chamber 127 from the suction channel. In this process, the debris (dust) near the suction channel is sucked into the dust storage chamber 127 to clean the objects. The airflow then enters the inner cavity of the inner shell 13 through the fan 4, and then blows out from the blowing channel 35 to inflate balloons, swimming rings, tires, etc.

[0035] In some embodiments, the inner shell 13 may be composed of two upper and lower shells connected by bolts or the like.

[0036] refer to Figure 1 The blowing member 3 includes a first connecting pipe 31 detachably connected to the first housing 11 and an inflation pipe 32 connected to one end of the first connecting pipe 31 away from the first housing 11 and used to fit the object to be filled. The first connecting pipe 31 has a blowing channel 35. When inflating different objects, inflation pipes 32 with different structures are used to fit the corresponding objects to be filled.

[0037] refer to Figure 7-9A connecting hole is provided at the end of the first shell 11, and the first shell 11 is connected to a concave part 111 extending to the first shell 11 toward the inner cavity of the first shell 11 at the connecting hole. The first shell 11 is provided with a connecting hole, and the concave part 111 forms a first ventilation hole connected to the connecting hole, and the hole wall of the first ventilation hole is formed with a first annular stop step, and the hole wall of the first ventilation hole is formed with a second annular stop step, and the second annular stop step is located on the side of the first annular stop step away from the end of the first shell 11, and the outer wall of the first connecting pipe 31 is formed with a first stop surface 34 that matches the first annular stop step, and the outer wall of the first connecting pipe 31 is formed with a second stop surface 33 that matches the second annular stop step, and the second annular stop step is formed with a guiding inclined surface for guiding the second stop surface 33 to slide, and a dust filter plate 8 is connected between the concave part 111 and the first shell 11 at the connecting hole, and the dust filter plate 8 has a plurality of filter holes. The first annular stop step and the second annular stop step cooperate with the first stop surface 34 and the second stop surface 33 respectively to connect the first connecting tube 31 to the first shell 11; the guiding slope allows the user to forcefully pull the first connecting tube 31 out of the first ventilation hole to achieve a detachable connection.

[0038] In some embodiments, the inner concave member 111 can be detachably connected to the first connecting tube 31 through interference fit.

[0039] refer to Figure 2-3 as well as Figure 6-7 The end of the fan 4 away from the blowing member 3 is connected to a shielding assembly 7 extending to the dust storage chamber 127. The shielding assembly 7 includes a plurality of support members 72 connected to the fan 4 and a shielding plate 71 connected to the end of the support member 72 away from the fan 4. The plurality of support members 72 are arranged at intervals along the circumferential direction of the shielding plate 71, and a filter screen (not shown in the figure) is connected between two adjacent support members 72. The shielding plate 71 projects toward the suction channel 22 to cover the suction channel 22. The shielding plate 71 can prevent dust and other debris from being directly sucked into the fan 4, and the wind flow can enter the fan 4 from the mesh of the filter screen.

[0040] refer to Figure 2-5 as well as Figure 7-9 The second housing 12 includes a first housing 121 connected to the first housing 11, a second housing 122 rotatably connected to the first housing 121 via a rotating shaft 126, the air suction member 2 is detachably connected to the second housing 122 away from the first housing 121, and the first housing 121 and the second housing 122 form a dust storage chamber 127. When there are a lot of debris in the dust storage chamber 127, the second housing 122 can be rotated to pour out the debris in the dust storage chamber 127.

[0041] In some embodiments, the first shell 121 is provided with a button slot for accommodating the driving button 123. One end of the driving button 123 is formed with a connecting hook 1231 hooked on the second shell 122 to cooperate with the rotating shaft 126 to seal the dust storage chamber 127. The other end of the driving button 123 is connected to the bottom of the button slot through a reset elastic member 1232. The reset elastic member 1232 is used to drive the connecting hook 1231 away from or close to the second shell 122. The user presses the driving button 123, and the driving button 123 squeezes the reset elastic member 1232, so that the connecting hook 1231 of the driving button 123 is separated from the second shell 122, and the constraint of the driving button 123 on the second shell 122 is released, so that the second shell 122 can rotate around the rotating shaft 126, and the debris in the dust storage chamber 127 is dumped. After dumping, the second shell 122 is rotated so that the end close to the driving button 123 is in contact and aligned with the first shell 121, and the elastic force of the reset elastic member 1232 (which can be a spring) resets the driving button 123, so that the connecting hook 1231 is hooked on the second shell 122 again, and the connection between the first shell 121 and the second shell 122 is realized.

[0042] A sealing plate 124 is connected to the inner side of the second housing 122, and the sealing plate 124 is rotatably connected to the second housing 122 via a torsion spring 125. The sealing plate 124 is used to prevent debris from flowing out of the air suction channel 22. When the fan 4 is working, the airflow drives the sealing plate 124 to rotate and open, and when the airflow stops, the torsion spring 125 drives the sealing plate 124 to close.

[0043] The end of the blowing member 3 away from the suction member 2 is connected to a brush 21 at the suction channel 22. The brush 21 of the blowing member 3 can enable the user to brush off the debris adhered to the object or brush out the debris in the gap when cleaning, so as to facilitate the adsorption of the fan 4.

[0044] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0045] The above is a relatively specific and detailed description of the present application through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
