[0024] The utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0025] Before the present invention is described in detail, it should be noted that similar elements are represented by the same reference numerals in the following description.

[0026] See also Figures 1 to 3 The first embodiment of the vacuum cleaner of the utility model which is convenient for replacing the filter element comprises a dust collecting unit 10, a joint member 4, a filter element 5, a shoulder strap unit 6, an electric control unit 7, and a suction unit 8.

[0027] The dust collecting unit 10 includes a housing 1 , a vacuum motor 2 disposed in the housing 1 , and a housing cover 3 disposed on the housing 1 .

[0028] See also Figures 2 to 4 The shell 1 has an upper shell 11 with a dust collecting space 111, a lower shell 12 that defines a flow guiding space 13 together with the upper shell 11, an inner shell 14 disposed in the flow guiding space 13, and a hook 15 disposed on the upper shell 11.

[0029] An air inlet 112 connected to the dust collecting space 111 is formed on the upper side of the upper shell 11. The flow guiding space 13 is located below the upper shell 11. An air outlet 121 connected to the flow guiding space 13 is formed on the lower side of the lower shell 12. In other words, the air inlet 112 is located above the shell 1, and the air outlet 121 is located below the shell 1.

[0030] The inner housing 14 has a housing portion 141 and an inner wall portion 142 disposed in the housing portion 141. Two openings 1411 are formed in the housing portion 141. The inner wall portion 142 defines a motor space 1421 communicating with the openings 1411.

[0031] The vacuum motor 2 is disposed in the motor space 1421 and has a motor module 21. The motor module 21 is used to draw the gas in the dust collecting space 111 to the motor space 1421.

[0032] The housing cover 3 is fixed to the bottom of the lower housing 12 by three screws 33 and has a slot 31 located downstream of the air outlet 121. A plurality of air holes 32 connected to the slot 31 are formed on the housing cover 3. Specifically, the slot 31 is located below the air outlet 121.

[0033] The connector 4 is located above the shell 1 and inserted into the air inlet 112 .

[0034] See also Figure 2 , Figure 3 ,and Figure 5 , the filter element 5 is located below the lower housing 12 and is detachably disposed in the slot 31. Specifically, the filter element 5 includes a tray 51 detachably disposed in the slot 31 and in a hollow shape, a filter screen 52 disposed on the tray 51 and facing the air outlet 121, and a handle 53 connected to the tray 51. Therefore, the user only needs to hold the handle 53 to pull out the tray 51 to replace the filter screen 52 or clean the filter screen 52. After completing the replacement or cleaning action, the tray 51 and the filter screen 52 can also be easily inserted back into the slot 31.

[0035] See also Figure 1 The shoulder strap unit 6 is disposed on the shell 1 and is used for being worn by a user (not shown).

[0036] The electric control unit 7 has a wire 71 disposed on the housing 1 and electrically connected to the vacuum motor 2, a handheld switch 72 connected to the wire 71 and used to start the vacuum motor 2, and two rechargeable batteries 73 disposed on the lower housing 12 and electrically connected to the vacuum motor 2. It should be noted that the function of the rechargeable battery 73 is to supply power to the vacuum motor 2, so in other variations of this embodiment, the number of the rechargeable batteries 73 may be only one or more than three, and is not limited thereto.

[0037] The suction unit 8 includes a pipe 81 disposed on the connector 4 and a suction head 82 disposed on the pipe 81. The air inlet 112, the connector 4, the pipe 81 and the suction head 82 are in communication.

[0038] See also Figure 4 , Figure 6 ,and Figure 7When the vacuum motor 2 is started, the outside air (see the dotted arrow) flows into the dust collecting space 111 through the connector 4. The air in the dust collecting space 111 flows through the vacuum motor 2 and then flows to the motor space 1421. Then, the air passes through the inner wall 142 and the shell cover 141 and the opening 1411 in sequence and then flows to the guide space 13. The air in the guide space 13 then passes through the air outlet 121 and the filter 52 and then is discharged downward. Therefore, the air inlet 112 is located upstream of the vacuum motor 2, and the air outlet 121 is located downstream of the vacuum motor 2.

[0039] In the present embodiment, the vacuum cleaner that is easy to replace the filter element is a backpack vacuum cleaner. It should be noted that in other variations of the present embodiment, the structural design of the shell cover 3 and the filter element 5 can also be applicable to different types of vacuum cleaners and should not be limited thereto.

[0040] See also Figure 8 ,and Fig. 9 , which is the second embodiment of the vacuum cleaner of the utility model which is convenient for replacing the filter element, and is referred to in conjunction with Figure 1 and Figure 2 The difference between the second embodiment and the first embodiment is that the electronic control unit 7 does not include the rechargeable battery 73, but the electronic control unit 7 also includes a power socket 74 arranged on the lower shell 12 of the shell 1 and electrically connected to the vacuum motor 2.

[0041] The power socket 74 is used for plugging a power cord (not shown) to supply power to the vacuum motor 2. When using the vacuum cleaner with easy filter replacement, the power cord can be hung around the hook 15 to prevent the power cord from being entangled with the user's body and causing trouble.

[0042] In addition, one side of the shell cover 3 is pivotally connected to the lower shell 12 of the housing 1. When the user loosens the screw 33, the shell cover 3 can be opened downward to facilitate cleaning of dust blocking the air holes 32 on the shell cover 3.

[0043] In summary, the utility model is a vacuum cleaner that is easy to replace the filter element. Since the filter element 5 can be detachably arranged in the slot 31, the user only needs to remove the filter element 5 from the slot 31 to clean or replace the filter element 5, so the purpose of the utility model can be achieved.

[0044] The above is only an embodiment of the present invention and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention.
