Description

Technical Field

[0001] The present application relates to the technical field of vacuum cleaners, and in particular to a handheld vacuum cleaner. Background Art

[0002] Vacuum cleaners are commonly used household cleaning tools. Their working principle is to drive the blades to rotate at high speed by an electric motor, generating a negative air pressure in a sealed housing to suck dust debris. Handheld vacuum cleaners are deeply favored by users because of their small size, light weight, convenient cleaning, and wide range of usage scenarios. There are usually two different usage methods for handheld vacuum cleaners in the prior art. One is that the main body component is far from the dust suction floor brush component, and they are connected by a dust suction pipe in the middle. When in use, the main body part is held by hand for dust suction. This usage state is convenient for the floor brush to reach under furniture for dust suction. The other is that the main body part is directly connected to the dust suction floor brush component, and the other end of the main body component is connected by a handle. Dust suction is carried out by holding the handle. The overall center of gravity of the vacuum cleaner in this usage state is lower, and it is more labor-saving when sucking dust.

[0003] In existing handheld vacuum cleaners, a pipe-shaped connection channel is usually formed on one side of the main body. Corresponding connection structures are provided at its upper and lower ends so that the vacuum cleaner can have two usage states. When sucking dust, it needs to enter the connection channel and then flow into the main body. And because the connection channel is usually small in diameter and the air inlet channel is long, it affects the dust suction efficiency. Moreover, the connection structure of the existing main body is complex, making the overall production cost of the vacuum cleaner with two usage states relatively high. Summary of the Utility Model

[0004] The purpose of the present utility model is to solve the above technical problems, and to provide a handheld vacuum cleaner. The air inlet channel of the vacuum cleaner in this application is directly communicated with the inner cavity, which improves the dust suction efficiency. Moreover, it has two usage states, the switching structure is simple, the production cost is reduced, and it has high practicability.

[0005] In order to achieve the above purpose, the technical solution of the present utility model is as follows:

[0006] A handheld vacuum cleaner, comprising a main body, a floor brush, a handle and a dust suction pipe. An air inlet channel is provided in the inner cavity of the main body and extends to the bottom of the main body to form a dust suction port. A separator is installed in the inner cavity of the main body. The separator is connected to the air inlet channel. A blower is provided at the upper end of the separator. After the air flow passes through the air inlet channel, it enters the separator for separation and then flows out. An extension part is provided at the upper end of the main body. A fixing groove is provided in the extension part, and a fixing lining is installed in the fixing groove. When the dust suction port is directly inserted into the floor brush, the handle is inserted into the fixing lining, and the handle serves as the handheld part. When the dust suction port is inserted into the dust suction pipe and the other end of the dust suction pipe is inserted into the floor brush, the fixing lining closes the fixing groove, and the extension part serves as the handheld part.

[0007] In this application, the air inlet duct provided in the main body is connected to the separator, and air enters through the outwardly extending dust suction port. The air inlet passage of the main body is short, enabling rapid air supply to the separator, thereby improving the dust suction efficiency. Moreover, the main body can be switched between two usage states. When the dust suction port is directly inserted into the floor brush, a handle is mounted through the fixed lining provided in the fixed slot. The center of gravity of the entire vacuum cleaner is lowered, and the handle serves as the holding part for dust suction, facilitating user operation. When it is necessary to suck dust in a space with a relatively small gap, the dust suction port is connected to the dust suction pipe, and the dust suction pipe is inserted into the floor brush, causing the main body to be located at a relatively upper position of the entire vacuum cleaner. At this time, the extended part of the main body serves as the holding part for use, and the fixed lining is in a closed state. The overall insertion structure is simple, and by providing the fixed lining, the form switching is facilitated without affecting the appearance, effectively improving the practicality of the vacuum cleaner while being user-friendly.

[0008] In one embodiment, the separator is spiral, and the separator is provided with a downwardly extending air guide pipe communicating with the air inlet duct.

[0009] In one embodiment, one side of the extended part is cylindrical, and a fixed slot is formed in the inner cavity. The fixed lining is adapted to the fixed slot and is inserted into the fixed slot.

[0010] In one embodiment, a first fixed wall extends downward from the lower side of the fixed lining, and a second fixed wall extends from the lining to the other end of the extended part. Both the first fixed wall and the second fixed wall are buckled to the inner cavity of the extended part and are fixed to the extended part by threaded connection.

[0011] In one embodiment, the middle part of the fixed lining is a plug-in slot, and mounting holes are provided on the side wall of the plug-in slot. The handle is fixed to the mounting holes by threaded connection.

[0012] In one embodiment, a limiting rib extends from the bottom of the plug-in slot, and a limiting groove is provided at the bottom of the handle. The limiting groove is clamped to the limiting rib.

[0013] In one embodiment, a sealing plug is provided at the opening of the plug-in slot to form a closed state.

[0014] In one embodiment, when the extended part serves as the holding part, the fixed lining is in a T shape, and the fixed lining is provided with a closed surface to close the fixed slot. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The embodiments of the present application provide a handheld vacuum cleaner, which is used to solve the technical problems that in the existing handheld vacuum cleaner, due to the relatively small diameter of the connecting channel and the relatively long air inlet channel, the dust collection efficiency is affected, and the connecting structure of the existing main body is complex, resulting in a relatively high overall production cost of the vacuum cleaner with two usage states.

[0022] In order to make the invention purpose, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0023] Please refer to Figures 1 to 6 The embodiments of the present application provide a handheld vacuum cleaner, including a main body 100, a floor brush 200, a handle 300 and a suction pipe 400. An air inlet channel 110 is provided in the inner cavity of the main body 100 and extends to the bottom of the main body 100 to form a dust suction port 120. A separator 130 is installed in the inner cavity of the main body 100. The separator 130 is connected to the air inlet channel 110. A blower 140 is provided at the upper end of the separator 130. After the air flows through the air inlet channel 110, it enters the separator 130 for separation and then flows out; an extension part 150 is provided at the upper end of the main body. A fixing groove 151 is provided in the extension part 150, and a fixed inner lining 500 is installed in the fixing groove 151; when the dust suction port 120 is directly inserted into the floor brush 200, the fixed inner lining 500 is inserted with the handle 300, and the handle 300 serves as a handheld part; when the dust suction port 120 is inserted into the suction pipe 400 and the other end of the suction pipe 400 is inserted into the floor brush 200, the fixed inner lining 500 closes the fixing groove 151, and the extension part 150 serves as a handheld part.

[0024] In this embodiment, a cavity is provided on the lower side of the inner cavity of the main body 100. The cavity forms a dust collection space. An air inlet duct 110 is provided in the cavity. The bottom of the air inlet duct 110 extends outward in a tubular shape, and the bottom is a dust suction port 120. The other end of the air inlet duct 110 communicates with a separator 130 inside the main body 100, and a blower 140 is installed on the upper side for dust suction. After the air flows through the dust suction port 120 and then through the air inlet duct 110, it enters the separator 130 for separation and filtration. The separator 130 is provided with a filter fence to ensure that dirt does not enter the blower 140. The air inlet channel of the main body 100 is short, and the air can quickly reach the separator 130 for separation, improving the dust suction efficiency. The upper end of the main body 100 extends upward to form an n-shaped extension 150. A fixing groove 151 is provided on one side of the extension 150. The shape of the fixing lining 500 is adapted to the fixing groove 151 and is fixed in the fixing groove 151. When the dust suction port 120 is directly inserted into the floor brush 200, the handle 300 is inserted into the fixing lining 500. In this usage state, the main body 100 is located at a lower position of the whole vacuum cleaner, and the center of gravity is lower. The handle 300 is used as the hand-held part and is operated through the handle 300 during the dust suction process, which is convenient for users. When the dust suction port 120 of the main body 100 is inserted into the suction pipe 400 and the bottom of the suction pipe 400 is inserted into the floor brush 200, at this time the main body 100 is located at a higher position of the vacuum cleaner, and the extension 150 can be directly used as the hand-held part without the need to install other additional hand-held components. At this time, the insertion port of the fixing lining 500 is in a closed state to ensure the integrity of the overall appearance. In this usage state, the floor brush 200 can extend into a space with a small gap for cleaning. When switching between the two usage states, the switching of the usage state is realized by switching the insertion state between the dust suction port 120 and the floor brush 200 and the suction pipe 400. Through the matching of the pipe diameters and direct insertion and cooperation, the operation is simple. Moreover, the extension 150 can be directly used as the hand-held part or the fixing position of the handle 300. By setting the fixing lining 500 to switch according to the usage state, the overall structure is simple and the production cost is reduced.

[0025] Further, the separator 130 is spiral, and the separator 130 is provided with a downwardly extending air guide pipe 131 communicating with the air inlet duct 110. The separator 130 forms a spiral air guide channel, and an air guide pipe 131 extends downward on one side. The air guide pipe 131 is directly connected to the air inlet duct 110. After the dust is sucked by the floor brush 200, it directly flows into the air guide pipe 131 through the air inlet duct 110 for separation, and large particle dirt is filtered out. The air duct is direct and fast, improving the dust suction efficiency.

[0026] Further, one side of the extension portion 150 is columnar, and a fixing groove 151 is formed in the inner cavity. The fixing inner lining 500 is adapted to the fixing groove 151 and is inserted into the fixing groove 151. One side of the extension portion 150 is a hollow column, and a fixing groove 151 is formed in the inner cavity. The fixing inner lining 500 is inserted into the fixing groove 151 to form a space for the fixing handle 300. Among them, a first fixing wall 510 extends downward from the fixing inner lining 500, and a second fixing wall 520 extends from the inner lining to the other end of the extension portion 150. Both the first fixing wall 510 and the second fixing wall 520 are buckled in the inner cavity of the extension portion 150 and are fixed to the extension portion 150 by threaded connection, so that both the upper and lower ends of the fixing inner lining 500 are fixed in the extension portion 150, ensuring that the handle 300 remains stable during installation, and the fixing method is simple and convenient for installation.

[0027] Further, the middle part of the fixing inner lining 500 is a plug-in groove 530, and mounting holes 540 are provided on the side wall of the plug-in groove 530. The handle 300 is fixed to the mounting holes by threaded connection. A limiting rib 531 extends from the bottom of the plug-in groove 530, and a limiting groove 310 is provided at the bottom of the handle 300. The limiting groove 310 is clamped to the limiting rib 531. The plug-in groove 530 formed in the middle of the fixing inner lining 500 is used for plugging the handle 300. The mounting holes 540 lead to the outside of the extension portion 150, and the handle 300 is fixed from the outer wall of the extension portion 150 by screws or studs, which is convenient for the disassembly and assembly of the handle 300 and can be quickly removed when switching the use state; the limiting rib 531 at the bottom of the plug-in groove 530 is horizontally arranged and corresponds to the limiting groove 310 at the bottom of the handle 300, which can be quickly positioned during installation and is not easy to loosen during use; when switching to the use state with the host 100 facing up, a sealing plug 600 is provided at the opening of the plug-in groove 530 to form a closed state. The sealing plug 600 can be made of silica gel material, which can quickly block the plug-in groove 530 to keep the overall appearance intact.

[0028] As an embodiment, when the extension portion 150 is used as a handheld portion, the fixing inner lining 500 is T-shaped, and the fixing inner lining 500 is provided with a closed surface 540 to close the fixing groove 151. In this embodiment, when the extension portion 150 is directly used as a handheld portion, the T-shaped fixing inner lining 500 is fixed to the top of the fixing groove 151, and a hole is provided on one side and is directly clamped to the inner wall of the extension portion 150. The closed surface 540 at the top of the fixing inner lining 500 is adapted to the opening of the fixing groove 151. In this use state, the fixing inner lining 500 can directly block the sealing groove to form a complete appearance, and the overall structure is simple.
