[0022] The air inlet of the handheld device is located at the center of the end face of the plug-in end, and the air outlet of the handheld device is located at the side of the plug-in end.

[0023] In this way, the air inlet of the main air outlet channel is located on the side wall of the support groove. There is no need to open the air inlet of the main air outlet channel on the end face of the support groove. The gas blows from the side of the plug-in end to the side wall of the support groove and enters the main air outlet channel without occupying the internal space of the equipment body.

[0024] In addition, not providing an air inlet of the main body air outlet channel on the end surface of the support groove can also improve the support strength of the end surface of the support groove.

[0060] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application.

[0061] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. The embodiments of this application are described in detail below in conjunction with the drawings.

[0062] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0063] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are orientations or positional relationships based on the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0064] The terms "first", "second", "third" (if any) in the specification and claims of this application and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the implementation of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0065] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.

[0066] As mentioned in the background technology, in the cleaning equipment in the related technology, the internal space of the equipment body is small, which is not conducive to the design and installation of the internal parts structure. If you want to achieve the reasonable design and installation of all parts inside the equipment, you need to expand the volume of the equipment body, which makes the equipment bulky and inconvenient to use.

[0067] Research has found that the reason for this problem is that the handheld structure has air inlets and outlets on the same end face. When the main body and the handheld structure are used in combination, the air inlet and outlet of the main body are connected to the corresponding air inlets and outlets. The air inlet and outlet of the main body are connected to the air inlet and outlet of the handheld structure on the same end face, resulting in the internal space of the main body being occupied by the air inlet and outlet, and the space is small.

[0068] In view of the above problems, the present application provides a cleaning device, which includes a device body and a handheld structure. The handheld structure has an air duct, and the two ends of the air duct respectively form a handheld device air inlet and a handheld device air exhaust port. The handheld device air inlet is located at one end of the handheld structure, and the handheld device air exhaust port is located on the side of the handheld structure. The device body has a main body air inlet channel and a main body air outlet channel. The main body air inlet channel is correspondingly connected to the handheld device air inlet, and the main body air outlet channel is correspondingly connected to the handheld device air exhaust port.

[0069] Therefore, the air inlet and the air outlet of the handheld structure are not at the same end. After the main body air outlet channel is connected to the handheld device air outlet, the main body air outlet channel does not need to be arranged on the opposite side of the end of the handheld structure with the air inlet, thereby not occupying too much internal space of the device body.

[0070] The specific implementation of the cleaning device provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0071] It should be noted that Figures 1 to 8 The schematic diagram of each component of the cleaning device is shown. The specific structure of the remaining components of the cleaning device is not limited to Figures 1 to 8 of examples.

[0072] Reference Figures 1 to 3 As shown, the present application provides a cleaning device, including: a device body 100 and a handheld structure 200, the handheld structure 200 is detachably connected to the device body 100, the handheld structure 200 has an air duct, and the two ends of the air duct respectively form a handheld device air inlet 300 and a handheld device air outlet 400, the handheld device air inlet 300 is located at one end of the handheld structure 200, and the handheld device air outlet 400 is located on the side of the handheld structure 200.

[0073] The device body 100 has a main body air inlet channel 110 and a main body air outlet channel 120 . The main body air inlet channel 110 is correspondingly connected to the handheld device air inlet 300 , and the main body air outlet channel 120 is correspondingly connected to the handheld device air outlet 400 .

[0074] When the cleaning device provided by the present application is used in combination with the device body 100 and the handheld structure 200, the gas enters the handheld structure 200 from the main air inlet channel 110 of the device body 100 through the handheld device air inlet 300, passes through the air duct and flows out from the handheld device exhaust port 400, and then enters the main air outlet channel 120 of the device body 100, and finally blows out from the main air outlet channel 120, reference Figure 3 The arrow in the middle indicates the direction.

[0075] Among them, the handheld device exhaust port 400 is located on the side of the handheld structure 200, and the air inlet and exhaust port of the handheld structure 200 are not at the same end. After the main body air outlet channel 120 is correspondingly connected with the handheld device exhaust port 400, the main body air outlet channel 120 does not need to be arranged on the opposite side of the end of the handheld structure 200 with the air inlet, so as not to occupy too much internal space of the device body 100, which is convenient for the design and installation of other structures of the main body, and provides more designable structural space. On the premise of meeting the internal parts structural design, it can also avoid the device body 100 from being too large, and facilitate the use of the device body 100.

[0076] Reference Figure 6 and Figure 7 As shown, in a possible implementation, a first sealing member 500 is further included, and the first sealing member 500 is disposed between the main body air inlet channel 110 and the handheld device air inlet port 300 .

[0077] Specifically, the first sealing member 500 may be a rubber sealing ring, which is bonded to the plug end 220 along the circumference of the air inlet 300 of the handheld device.

[0078] In this way, the first seal 500 improves the sealing between the main body air inlet channel 110 and the handset air inlet 300. When the gas enters the mobile phone structure from the main body air inlet channel 110 through the handset air inlet 300, the first seal 500 can prevent the gas from leaking during this process.

[0079] In a possible implementation, an external structure (not shown in the figure) is also included. The external structure is constructed to be connected to the handheld structure 200 when the handheld structure 200 is detached from the device body 100, and together with the handheld structure 200, form a cleaning execution device.

[0080] When the handheld structure 200 is used alone, it is connected to an external structure to form a cleaning execution device, which has multiple uses, increases the usage scenarios of the handheld structure 200, and improves the functionality and applicability of the handheld structure 200.

[0081] In a possible implementation, a second sealing member 600 is further included, and the second sealing member 600 is disposed between the handset air outlet 400 and the device body 100 .

[0082] Specifically, the second sealing member 600 may be a rubber sealing strip, which is bonded to the side surface of the plug-in end 220 along the circumference of the air outlet of the handheld device.

[0083] In this way, the second sealing member 600 improves the sealing between the handset air outlet 400 and the device body 100 .

[0084] In a possible implementation, a connector 700 is further included, and the first seal 500 and the second seal 600 are connected by the connector 700. The first seal 500 and the connector 700 are located in the same plane, and the first seal 500, the second seal 600 and the connector 700 are integrally formed.

[0085] Specifically, the connecting member 700 may be two rubber strips, one end of the rubber strips is connected to the first sealing member 500 , and the other ends of the two rubber strips are respectively connected to two opposite ends of the second sealing member 600 .

[0086] In this way, the first sealing member 500 , the second sealing member 600 and the connecting member 700 are integrally formed, which facilitates the installation and manufacture of the first sealing member 500 , the second sealing member 600 and the connecting member 700 .

[0087] Reference Figures 4 to 6 As shown, in a possible implementation, the handheld structure 200 includes a handheld body 210 and a plug-in end 220 located at an end of the handheld body 210 .

[0088] A placement groove 130 is disposed on the side of the device body 100 , and a supporting groove 140 communicating with the placement groove 130 is disposed inside the device body 100 .

[0089] The plug-in end 220 is plugged into the supporting groove 140 , and the supporting groove 140 covers the plug-in end 220 . Part of the side surface of the handheld body 210 is located in the placement groove 130 .

[0090] Specifically, an operating handle 211 is provided on the handheld body 210, and the plug-in end 220 is provided at the end of the handheld body 210 away from the operating handle 211. A person can move or start the handheld structure 200 by holding the operating handle 211. The specific structure of the operating handle 211 is not limited here.

[0091] In this way, when the handheld structure 200 is combined with the device body 100, hold the operating handle 211 and plug the plug-in end 220 into the support groove 140. Part of the side of the handheld body 210 can be located in the placement groove 130. The support groove 140 covers the plug-in end 220. On the one hand, it guides the plugging of the plug-in end 220. On the other hand, the support groove 140 can protect the connection part between the handheld structure 200 and the device body 100 to make the connection stable.

[0092] In addition, it can be understood that after the support groove 140 covers the plug end 220, the connection position between the handheld structure 200 and the device body 100 can be hidden in the support groove 140, without too much redundant connection structure exposed, and the overall aesthetics can be improved.

[0093] Or, refer to Figures 2 to 5 As shown, the opening space of the placement groove 130 is adapted to the operating handle 211 and the handheld body 210. Specifically, it is understood that the placement groove 130 can semi-cover part of the operating handle 211 and part of the handheld body 210. Such a setting can further reduce the exposed connection structure when the device body 100 and the handheld structure 200 are used in combination, so that the overall appearance presents a streamlined shape, further improving the aesthetics of the overall device.

[0094] In one possible implementation, the air outlet of the main body air inlet channel 110 is located at the center of the support groove 140 and is correspondingly connected to the handheld device air inlet 300, and the air inlet of the main body air outlet channel 120 is located on the side wall of the support groove 140 and is correspondingly connected to the handheld device exhaust port 400.

[0095] The handset air inlet 300 is located at the center of the end surface of the plug end 220 , and the handset air outlet 400 is located at the side of the plug end 220 .

[0096] In this way, the air inlet of the main air outlet channel 120 is located on the side wall of the support groove 140. There is no need to open the air inlet of the main air outlet channel 120 on the end face of the support groove 140. The gas blows from the side of the plug-in end 220 to the side wall of the support groove 140 and enters the main air outlet channel 120 without occupying the internal space of the equipment body 100.

[0097] In addition, not providing an air inlet of the main air outlet channel 120 on the end surface of the support groove 140 is equivalent to not excessively damaging the integrity of the end surface of the support groove 140 , and can also improve the support strength of the end surface of the support groove 140 .

[0098] Reference Figures 3 to 8 As shown, in a possible implementation, the handheld body 210 includes a shell 212, a support member 213 and a driving member 214 for providing suction force.

[0099] The support member 213 is partially inserted into the shell 212 . The support member 213 has a cavity inside. The driving member 214 is disposed in the cavity. At least part of the support member 213 and the shell 212 adjacent to the support member 213 form a plug-in end 220 .

[0100] Specifically, the driving member 214 is a related technology in this field, and only needs to be able to provide suction force, and its structure is not too limited here.

[0101] On the one hand, the support member 213 provides an installation position for the driving member 214. On the other hand, part of the support member 213 and the shell 212 adjacent to the support member 213 form a plug-in end 220, which has the effect of one object for multiple uses, helps to reduce costs, and at the same time makes the overall structure highly stable.

[0102] In one possible implementation, part of the cavity forms an air duct, the end face of the support member 213 facing the device body 100 forms the end face of the plug-in end 220 , the handheld device air inlet 300 corresponds to the suction port of the driving member 214 , and the handheld device exhaust port 400 is located on the side of the support member 213 .

[0103] In this way, a cavity is formed by using a support member 213, and the cavity is equipped with a driving member 214 and serves as an air duct. The handheld device air inlet 300 and the handheld device air outlet 400 are formed on the support member 213, and the handheld device air outlet 400 is on the side. The overall structure is simple and compact, and the space utilization rate is high.

[0104] In one possible implementation, the side of the support member 213 has a groove 800, the notch of the groove 800 faces the side wall of the support groove 140, the notch forms the handheld device exhaust port 400, and the groove 800 has a first side wall 810 and a second side wall 820 opposite to each other, and the first side wall 810 faces the handheld body 210.

[0105] At least one first through hole 821 connecting the air passage and the groove 800 is defined on the second side wall 820 .

[0106] In this way, the gas is blown out of the handheld device exhaust port 400 from the air duct through the first through hole 821, and the groove 800 faces the side wall of the support groove 140. The handheld device exhaust port 400 is formed by processing the groove 800 on the side of the support member 213, which further makes the structure compact and fully utilizes the space.

[0107] In a possible implementation, in order to reduce wind resistance, a notch is provided on the first side wall 810 , and the notch is connected to the end surface of the support member 213 facing the device body 100 , so that the notch is inclined.

[0108] In this way, the notch makes the slot inclined, and the direction of the gas blown out from the handheld device exhaust port 400 is obliquely outward relative to the axial direction of the handheld body 210, which fully utilizes the structural space while reducing wind resistance, which is equivalent to blowing obliquely toward the main body outlet channel 120.

[0109] In a possible implementation, in order to improve ventilation, a clamping portion 830 is provided in the groove 800, and a second through hole 831 is provided on the side of the clamping portion 830 facing the notch, and the second through hole 831 connects the air duct and the groove 800. The second through hole 831 expands the ventilation area of ​​the groove 800 and improves ventilation.

[0110] In a possible implementation, the clamping portion 830 is connected to the first side wall 810 .

[0111] After the clamping portion 830 is connected to the first side wall 810 , it is equivalent to forming reinforcing ribs on both side walls of the second through hole 831 , which can guide the gas in the second through hole 831 on the one hand, and improve the stability of the clamping portion 830 on the other hand.

[0112] In a possible implementation, the groove 800 is an arc-shaped groove, the center of the groove 800 coincides with the center of the end surface of the plug end 220 , and the center angle of the groove 800 is less than 90°.

[0113] Specifically, the center angle of the groove 800 is greater than 30°. If the center angle of the groove 800 is too small, the ventilation volume will be reduced, and if it is too large, the overall strength of the support member 213 will be damaged. In addition, the arc groove has low wind resistance, which is conducive to the circulation of gas.

[0114] In a possible implementation, the external structure is a dust cup structure, and the clamping portion 830 is clamped with the dust cup structure. The dust cup structure is a related technology in this field, and its specific structure is not limited here. The dust cup structure is detachably connected to the handheld structure 200 through the clamping portion 830, which is convenient for use.

[0115] The cleaning device provided in the embodiment of the present application includes a device body 100 and a handheld structure 200. The handheld structure 200 has an air duct, and the two ends of the air duct form a handheld device air inlet 300 and a handheld device air outlet 400 respectively. The handheld device air inlet 300 is located at one end of the handheld structure 200, and the handheld device air outlet 400 is located on the side of the handheld structure 200. The device body 100 has a main body air inlet channel 110 and a main body air outlet channel 120. The main body air inlet channel 110 is correspondingly connected with the handheld device air inlet 300, and the main body air outlet channel 120 is correspondingly connected with the handheld device air outlet 400. The air inlet and the air outlet of the handheld structure 200 are not at the same end. After the main body air outlet channel 120 is correspondingly connected with the handheld device air outlet 400, the main body air outlet channel 120 does not need to be set on the opposite side of the end of the handheld structure 200 with the air inlet, so as not to occupy too much of the internal space of the device body 100, expand the internal available space, and facilitate the design and installation of other structures of the main body.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
