[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0034] Example 1

[0035] Referring to Figures 1 to 5, the first embodiment of the present invention provides a bag-type dust removal device that is easy to replace the dust bag. The bag-type dust removal device that is easy to replace the dust bag includes a shell 100, a lifting mechanism 200 and a locking mechanism 300. The shell 100 is used to install other mechanisms for replacing the dust bag, the lifting mechanism 200 is used to install and remove the dust bag, and the locking mechanism 300 is used to lock the dust bag after it is placed in to prevent the dust bag from being displaced.

[0036] Specifically, the housing 100 includes an air inlet 101 and an air outlet 102 , and a first slide slot 103 is provided on the housing 100 ; the air inlet 101 and the air outlet 102 are used for passing smoke.

[0037] The lifting mechanism 200 is provided on the housing 100 and includes a mounting frame 201 slidably connected to the first slide slot 103, a drive module 202 provided on the housing 100, a transmission module 203 provided on the mounting frame 201 and cooperating with the drive module 202, and a trigger module 204 provided on the mounting frame 201 and cooperating with the transmission module 203. The mounting frame 201 is provided with a slot 201a, into which the dust bag A is engaged.

[0038] The mounting frame 201 is slidably connected to the mounting frame 201, and a rubber pad can be added between them to prevent dust from entering the lifting mechanism 200 when the bag dust removal device is working. The driving module 202 is used to drive the transmission module 203 to drive the mounting frame 201 to move upward, and the trigger module 204 is used to move the transmission module 203 so that the driving module 202 drives the transmission module 203 to work.

[0039] Furthermore, a through hole for passing compressed air is provided at a corresponding position of the housing 100 . When the mounting frame 201 is reset, the bottom of the mounting frame 201 contacts the bottom of the housing 100 .

[0040] The locking mechanism 300 is set on the installation frame 201 and is cooperated with the card slot 201a. When the installation frame 201 falls into the shell 100, the locking mechanism 300 holds the dust bag A tightly. When the installation frame 201 is lifted out of the shell 100, the locking mechanism 300 opens, making it convenient for the staff to take out the dust bag A.

[0041] During use, the staff moves the transmission module 203 by triggering the module 204, and then turns on the driving module 202 to drive the transmission module 203. The transmission module 203 drives the installation frame 201 to move up along the first slide groove 103 and opens the locking mechanism 300. The staff takes out the dirty dust bag A, and inserts the new dust bag A into the slot 201a. Then, the staff turns on the driving module 202 to drive the transmission module 203. The transmission module 203 drives the installation frame 201 to move down along the first slide groove 103 and locks the locking mechanism 300, clamping the dust bag A to complete the replacement.

[0042] Example 2

[0043] 1 to 8 , a second embodiment of the present invention is shown, which is based on the previous embodiment.

[0044] A plurality of first sliding grooves 103 , lifting mechanisms 200 , locking grooves 201 a and locking mechanisms 300 are correspondingly provided to install a plurality of dust removal bags A.

[0045] The driving module 202 includes a motor 202 a and a plurality of gears 202 b disposed on an output shaft of the motor 202 a , wherein the gears 202 b correspond to the mounting frame 201 on a one-to-one basis.

[0046] The trigger module 204 includes a push rod 204a arranged on the mounting frame 201, a small ball 204b arranged at the end of the push rod 204a, and a wedge rod 204c slidably connected to the mounting frame 201. The wedge rod 204c passes through the mounting frame 201, and the small ball 204b contacts the end of the push rod 204a and the wedge surface of the wedge rod 204c.

[0047] The transmission module 203 includes a rack 203a fixedly connected to the outer end of the wedge rod 204c, and the rack 203a can be meshed with the gear 202b.

[0048] Furthermore, the driving modules 202 are arranged on both sides of the installation frame 201 , and the motors 202 a rotate synchronously to increase the stability of the lifting installation frame 201 .

[0049] Different trigger modules 204 can be used to engage the rack 203a of the installation frame 201 that needs to be raised with its corresponding gear 202b, so that only the required installation frame 201 is raised, which also makes it convenient for workers to replace the dust bag A.

[0050] By pressing the push rod 204a downward, the ball 204b moves downward, and the ball 204b moves downward to squeeze the wedge rod 204c to move outward, thereby driving the rack 203a to move outward and engage with its corresponding gear 202b.

[0051] Furthermore, a handle is provided on the push rod 204a for the convenience of use by the staff.

[0052] The movement process is shown in Figures 5 and 8.

[0053] A fixing rod 202a-1 is fixedly connected to the push rod 204a, and a "J"-shaped arc groove 201b is opened on the mounting frame 201. The fixing rod 202a-1 is slidably connected in the arc groove 201b. When the staff presses down the push rod 204a, it is rotated 90 degrees so that the fixing rod 202a-1 is stuck in the tail end of the "J" shape of the arc groove 201b to fix the position of the wedge rod 204c.

[0054] Two wedge rods 204c are provided on both sides of the ball 204b, and a first spring 202d is provided between the two wedge rods 204c.

[0055] The first spring 202d is used when the installation frame 201 is reset. The staff rotates the push rod 204a 90 degrees in the opposite direction. Under the contraction force of the first spring 202d, the two wedge rods 204c move closer, squeezing the small ball 204b to move upward, and the small ball 204b drives the push rod 204a to move upward, so that the fixed rod 202a-1 of the push rod 204a is stuck in the "J"-shaped head of the arc groove 201b, so that the rack 203a is disengaged from the gear 202b. When the drive module 202 is turned on, it no longer drives the installation frame 201 to move upward.

[0056] Example 3

[0057] 1 to 11 , there is shown a third embodiment of the present invention, which is based on the first two embodiments.

[0058] 9 and 10 , the locking mechanism 300 includes a slide bar 301 slidably connected to the mounting frame 201, a rotating block 302 rotatably connected to the mounting frame 201, and a baffle 303 fixedly connected to the rotating block 302. A second spring 304 is connected between the slide bar 301 and the mounting frame 201. A slider 301a is fixedly connected to the slide bar 301. A second sliding groove 302a is provided on the rotating block 302. The slider 301a is slidably connected to the second sliding groove 302a, and the baffle 303 is in contact with the dust bag A.

[0059] The second chute 302a includes a first section S and a second section P, and the angle between the first section S and the second section P is 135 degrees. The rotation center of the rotating block 302 and the second chute 302a are shown in FIG10 .

[0060] When the locking module is moved out of the housing 100, the slide rod 301 pops out of the installation frame 201 under the contraction force of the second spring 304. Since the slider 301a on the slide rod 301 is slidably connected to the second slide groove 302a, it drives the rotating block 302 to rotate, thereby driving the baffle 303 to open, making it convenient for the staff to take out the dust bag A.

[0061] The housing 100 is provided with a wedge 104, and the end of the slide bar 301 slides in contact with the wedge 104. Because the wedge 104 cooperates with the slide bar 301, when the locking mechanism 300 is retracted into the housing 100, the slide bar 301, restrained by the wedge 104, retracts into the mounting frame 201, simultaneously driving the baffle 303 to close and lock the dust bag A.

[0062] Referring to Figures 1 to 13 , during use, a worker selects the installation frame 201 to be removed and presses down the push rod 204a on the installation frame 201. This push rod 204a drives the ball 204b downward, which in turn pushes the wedge rod 204c outward, thereby driving the rack 203a outward and engaging with its corresponding gear 202b. The push rod 204a is then rotated 90 degrees, causing it to engage the tail end of the "J"-shaped arcuate slot 201b, thereby securing the wedge rod 204c in place.

[0063] Start the motor 202a, and the motor 202a drives the gears 202b to rotate. Since the rack 203a is engaged with the gear 202b, the installation frame 201 moves up. When the installation frame 201 moves up, after the locking module moves out of the shell 100, the slide bar 301 pops out of the installation frame 201 under the contraction force of the second spring 304. Since the slider 301a on the slide bar 301 is slidably connected to the second slide groove 302a, it drives the rotating block 302 to rotate, thereby driving the baffle 303 to open, making it convenient for the staff to take out the dust bag A.

[0064] The staff takes out the dirty dust bag A, inserts the new dust bag A into the slot 201a, and then turns on the motor 202a. The motor 202a drives the gears 202b to rotate, and the gears 202b drive the meshing rack 203a to move, driving the installation frame 201 to move down along the first slide groove 103. When the locking mechanism 300 is retracted into the shell 100, under the restriction of the wedge block 104, the slide rod 301 retracts the installation frame 201, and at the same time drives the baffle 303 to close and lock the dust bag A.

[0065] After the reset is completed, the staff rotates the push rod 204a 90 degrees in the opposite direction. Under the contraction force of the first spring 202d, the two wedge rods 204c move closer, squeezing the ball 204b to move upward, and the ball 204b drives the push rod 204a to move upward, so that the fixed rod 202a-1 of the push rod 204a is stuck in the "J"-shaped head of the arc groove 201b, so that the rack 203a is disengaged from the gear 202b, and the installation is completed.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
