detailed description

In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the present disclosure will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present disclosure. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concepts of the present disclosure.

The drawings are not to scale, some details may have been omitted for the sake of clarity. The shapes of the various regions shown in the figures and the relative sizes and positional relationships between them are only exemplary, and in practice, there may be deviations due to manufacturing tolerances or technical limitations, and those skilled in the art may vary according to actual needs. Regions/layers with different shapes, sizes, relative positions can be additionally designed.

Obviously, the described embodiments are some, but not all, embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

In addition, the technical features involved in the different embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other.

As there is a problem in the background art, in response to this problem, the present disclosure provides users with another option, adding a dust bag inside the dust bucket to form a two-in-one replaceable assembly. For users who do not want to dump the dust in the dust bucket, a disposable dust bag can be used. In this way, after the cleaning is completed, the user only needs to close the inlet of the dust bag, take out the dust bag from the body, and throw it away. While in order to detachably mount the above dust bag to the cleaning device, a support structure that is individually detachably connected to the cleaning device may be provided.

In the first embodiment of the present disclosure, as shown in FIG. 1 , a dust bag for cleaning equipment is provided. The dust bag is a separate accessory as a whole. The plates 6 are connected in sequence, and first, second, and

third seals

3, 5, and 7 are arranged between the above components or some of the components to prevent leakage of dust and garbage.

The inner card board 2 provides a support for fixing the bag body 1 thereon. The bag body 1 can be bonded to the inner card plate 2 and the opening of the bag body 1 around the opening of the bag body 1 by gluing. around the corresponding openings, so that the above openings correspond to form a unique garbage inlet channel.

The inner card board 2 and the outer card board 6 can be the same hard plate, and in this case, when the dust bag is taken out, the opening of the dust bag cannot provide sealing. In order to prevent the garbage in the dust bag from leaking out of the opening when the cleaning process is finished, when the dust bag is removed from the cleaning device, the present disclosure improves the inner and outer cardboards. The inner cardboard 2 and the outer cardboard 6 are two separate and identical pieces. Or different rigid boards, rib edges are arranged on the left and right edges of the opposite surfaces of the inner and outer clamping plates, and the inner and outer clamping plates are respectively bonded and fixed with the above-mentioned rib edges, thereby forming a cavity, and a suction plate is arranged in the cavity. plate, the cavity provides a space for the draw plate 9 to slide. The purpose of providing the suction plate 9 is to provide a seal for the opening of the dust bag through the extraction of the suction plate. The openings corresponding to the opening of the plate and the opening of the dust bag are aligned with the above openings to form a garbage channel. When the extraction plate is pulled down, the sealing tape above the extraction plate will seal the above openings.

Specifically, a soft sealing tape 4 is fixed on the upper part of the drawing board 9. Preferably, the soft sealing tape 4 can be a paper tape with certain flexibility and toughness. The connection between the soft sealing tape 4 and the upper part of the drawing board 9 can be made of glue. The other end of the soft sealing tape 4 is connected to the inner card board 2 or the outer card board 6 , preferably the inner card board 2 , by means of adhesive. In this way, when the drawer 9 is at the uppermost end, the openings of the inner card 2, the drawer 9 and the outer card 6 are all aligned with the opening of the bag body 1, and the soft sealing tape 4 is located at the uppermost end of the drawer 9 in a folded state. When the dust bag is filled with dust and garbage, the suction plate 9 is pulled down, and the suction plate 9 slides between the inner and outer card plates and pulls both ends to be fixed on the suction plate 9 and the soft sealing tape on the upper part of the inner/outer card plate. 4 moves downwards, thereby covering the opening on the inner card plate 2 and achieving a general seal of the dust bag.

Of course, in order to achieve the desired effect, the width of the inner and outer clips is slightly larger than the maximum width of the garbage inlet on the bag body 1, preferably greater than 2-8mm; the width of the drawer 9 is also greater than the maximum width of the garbage inlet on the bag body 1, preferably 2-6mm; it is clear that the width of the extraction plate 9 is smaller than the width of the inner and

outer clamping plates

2 and 6, so that a cavity for the sliding of the extraction plate 9 can be formed between the inner and outer clamping plates; and the width of the soft sealing tape 4 can be Roughly equal to the width of the suction plate 9 or slightly smaller, as long as the width of the soft sealing tape 4 with the smallest dimension is greater than or equal to the maximum width of the opening on the dust bag/inner card board 2 . On the basis of the above dimensions, the sliding of the suction plate 9 drives the soft sealing band 4 downward to cover the inlet of the dust bag to achieve a general sealing effect.

It can be understood that the mounting assembly formed by the inner card board 2, the outer card board 6, and the drawer plate 9 can also be in other forms, for example, an integrally formed plastic component can form a frame, and a separate drawer plate (which can be rigid material) pulls and slides in the frame. Furthermore, the mounting assembly can be formed to be detachably connected to the bag body 1 , the user only needs to seal the bag body and throw it away after use, and the frame can be reused again, reducing the cost of consumables.

As can be seen from Fig. 1, in addition to forming the dust bag support, the installation components should also ensure the airtightness during use (including normal vacuuming and taking out the dust bag) to avoid spillage. Especially during the movement of the drawer plate 9, for this purpose, a sealing member around the opening can be provided between the inner card plate 2 and the drawer plate 9, and between the drawer plate 9 and the outer card plate 6, which can substantially ensure the suction During the pulling process of the plate 9, the garbage at the mouth of the bag will not leak; more preferably, the above-mentioned seals are preferably arranged on the side of the inner card board 2 close to the suction plate 9, and the outer card plate 6 close to the suction plate 9. Moreover, when the drawing plate 9 is pulled out, the sealing element on the inner card plate 2 can also substantially seal the soft sealing band 4 .

Above, the inner and

outer clamps

2 and 6 are fixed to form a whole, and the two sides of the whole are formed as hard parts with a certain thickness. From the above description, the width of the inner and outer clamps is larger than the maximum width of the dust bag suction port, so the inner and outer clamps The rigid monolithic sides formed by the plate provide the assembly support for the dustbag monolith.

As for the specific dust bag material, the innermost layer is spunbond, the middle layer is meltblown filter layer, the outermost layer is spunbond, and the inner and outer layers are mainly used to protect the middle filter layer. At the same time, since some users are allergic, allergic phenomena may occur during the operation of the dust bag. For this reason, an auxiliary agent is added outside the spunbond layer, generally using a spraying process, generally spraying on the outer layer material, preferably, the The adjuvant is an anti-allergen. After using this additive, the effect of sterilizing and removing mites can be achieved, especially for Staphylococcus aureus, Aspergillus niger, Aspergillus terreus, Candida albicans and other molds/fungi, and at the same time, it can achieve isolation or elimination of mite allergens and pollen allergens , dog dander allergens, cat dander allergens, live mites, etc., to achieve the effect of removing mites.

ZINC OMADINE FPS dispersion is a highly effective broad-spectrum fungicide that effectively protects products from mold, yeast, algae and bacterial infection. ZINC OMADINE FPS should be added early in the production process. The amount of effective preservative in a product depends on several factors, including the susceptibility of the product formulation to microorganisms, the extent of the infecting microorganisms, the species involved, pH, temperature, and the period of protection of the product.

Referring to FIG. 3 , the lower part of the main body 18 is formed with an installation part where the cyclone assembly or the supporting member can be installed, and the user can selectively connect and install the cyclone assembly or the supporting member to the main body 18 in a detachable manner, and then install the dust bucket, Finally, a complete vacuuming airflow channel is formed.

As shown in FIG. 3 , the top structure includes a hollow ventilated mesh 12. The arrangement of the ventilated mesh 12 ensures that the airflow generated by the airflow generating device in the main body of the cleaning device can flow through the dust bucket without any obstruction. As for the larger airflow blocking, the ventilation grille also realizes the function of a partition, preventing the dust bag body from sticking to the main body of the cleaning equipment due to the airflow generated by the airflow generating device, and blocking the airflow and causing the suction to drop. The top structure is also provided with a buckle groove 11 that cooperates with the buckle protrusion 13 on the host. When the bracket is installed, first align the buckle groove 11 with the buckle protrusion 13 on the host, and then rotate to fix it.

The side structure includes a bracket air intake channel 14, bracket legs 23, snap fastener components 16, etc. corresponding to the dirty air inlet 17 and corresponding to the opening on the outer card board 6 of the dust bag; the outer side of the bracket air intake channel 14 Abutting against the end of the dirty air inlet 17, in order to ensure the air tightness, there is a flange on the outside of the air inlet channel 14 of the bracket, the flange is close to the channel inlet, the flange is provided with a groove for the sealing ring 15 to be installed, and the sealing The inner diameter of the ring 15 is comparable to the outer diameter of the channel inlet so that the sealing ring 15 can seal against the end of the dirty air inlet 17 when the bracket is installed in the cleaning device.

The inner side of the bracket air inlet channel 14 corresponds to the opening of the outer card plate 6 described in FIG. 1 above, and a sealing member 7 can be provided along the butt inlet or opening on the outer side of the bracket inlet channel 14 or the outer card plate 6 , A sealed air flow channel is thereby also formed.

Referring to FIG. 6 , opposite chutes 22 are formed on the bracket legs 23 to be inserted into both sides of the inner and

outer clamping plates

2 and 6 of the dust bag. When the inner and

outer clamping plates

2 and 6 slide to the uppermost end in the sliding grooves 22, The inner opening of the air inlet channel 14 of the bracket is just aligned with the opening on the outer card board 6, and the entire air flow channel is connected at this time, and the cleaning device can work normally after it is turned on. The length of the chute 22 can be equal to or shorter than the longitudinal lengths of the inner and

outer clips

2 and 6. The specific shape of the chute 22 can preferably be that when the inner and

outer clips

2 and 6 are inserted upward from the opening at the bottom of the chute 22, the chute 22 is located at the bottom of the chute 22. A rail is provided in the direction parallel to the outer card board 6, which restricts the inner and

outer card plates

2 and 6 to move only in the direction of the chute but not in the direction perpendicular to the chute 22, so as to ensure the air intake passage of the bracket. Sealed butt joint between 14 and the opening of the outer card board 6 .

From the above, after the inner and

outer card plates

2 and 6 of the dust bag are slid in along the chute 22 on the bracket, a locking device is also provided to lock the position of the dust bag relative to the bracket. Referring to Figs. 2, 5-6, the snap assembly 16 cooperates with the snap stop bar 8 shown in Fig. 1 . The snap stop strip 8 is a raised folding strip arranged on the lower part of the upper opening of the outer card board 6 . The snap stop strip 8 has a certain thickness, and preferably can be made of the same material as the inner card board 2 and the outer card board 6 , The structure of the same thickness, which can save materials, and its production can be based on the leftovers after cutting the inner and outer pallets. The working position of the snap stop strip 8 is the lower edge of the raised fold along the lateral direction of the outer card plate 6. When the inner and

outer card plates

2 and 6 of the dust bag slide into the end point of the chute 22, the spring buckle assembly on the bracket 16 catches the above-mentioned lower edge, thereby restricting the exit movement of the dust bag as a whole along the chute 22.

The elastic snap assembly 16 on the bracket is an elastic structure that can move in the lateral direction (along the radial direction of the dust bucket of the cleaning equipment). 8 Push the elastic buckle assembly 16 outward to enable the inner and outer clips to slide in smoothly. When the raised elastic buckle stop bar 8 passes over the elastic buckle assembly 16, the elastic buckle assembly 16 is reset under the action of the restoring force, and the buckle is locked. The lower edge of the raised snap stop bar 8, at this time, the inner and outer clamping plates reach the end point of the chute 22, and the dust bag is fixed.

The elastic buckle assembly 16 can be an elastic piece along the direction of the bracket leg 23, the lowermost end of the elastic piece is provided with an inward convex buckle, the lower part of the raised buckle is an inclined surface, and the upper part is a small plane perpendicular to the extension direction of the raised buckle, and the inclined surface is inclined. The surface makes the snap stop strips 8 smoothly deform the raised buckles when the inner and outer clips of the dust bag enter the chute 22. When the inner and outer clips reach the end point of the chute 22, the snap stop strips 8 pass over the snap components and have been removed. The deformed snap snap assembly 16 is reset under the action of the restoring elastic force, and the small plane on it and the lower edge of the snap snap stop bar 8 form a limit.

However, since the bracket is a multiple-use structure, if the elastic buckle assembly 16 on it loses its restoring force or is easily broken after a limited number of deformations, it will affect the normal use of the overall structure.

Based on this, the spring buckle assembly 16 can be optimized. As shown in FIGS. 5 , 7 and 8 , a spring buckle assembly is provided on the bracket at a position corresponding to the dust bag spring buckle stop bar 8 , and the spring buckle assembly 16 includes an elastic member 20 . And the elastic buckle 21, the elastic buckle 21 is integrally formed, including the sliding part 211, the abutting part 212 and the hook part 213, the above elastic buckle 21 as a whole extends along the radial direction of the top of the bracket, and is molded on the bracket with accommodating and The corresponding groove for fixing the elastic buckle 21, the groove includes a spring buckle fixing wall 24 at one end and an elastic component clip 26 at the other end. The elastic component clip 26 is used to fix the elastic component 20. It can be understood that when When the elastic member 20 is a spring, the spring is longitudinally inserted into the elastic member clip 26 so that the spring can only be stretched or compressed along the longitudinal axis of the spring in the groove, and other movement modes that may jump out of the groove are restricted.

The snap assembly 16 includes a sliding part 211 , abutting part 212 and a hooking part 213 . As shown in FIGS. 5 and 6 , the sliding part 211 is generally along the radial direction of the top structure of the stent; the abutting part 212 is substantially parallel to the sliding part 211 and is located at one end close to the hook part 213 , and the abutting part 212 has a direction toward the groove. The protrusion of the elastic component clip 26; a hook portion 213 is provided at one end close to the radial center, and the hook portion 213 is formed as a roughly wedge-shaped member, including an outer inclined surface and an inner vertical surface (here the inner and outer It is relative to the body of the sliding part 211 ), the above inclined surface can respond to the contact and interference with the snap stop bars 8 on the inner and

outer card plates

2 and 6 of the dust bag, so that the abutting part 212 compresses the elastic member 20 toward the Displacement away from the snap stop bar 8 on the outer card plate 6 , when the inner and outer card plates slide to release the contact interference between the inclined surface and the snap stop bar 8 , the abutting portion 212 is under the action of the restoring force of the elastic member 211 . Displacement in the direction of the snap stop bar 8, the upper vertical surface is buckled with the lower edge of the snap stop bar 8, thereby realizing the locking of the dust bag as a whole. The above movement process is: due to the setting of the snap stop bar 8, the hook portion 213 is pushed by the snap stop bar 8 to drive the sliding portion 211 to move, and the movement of the sliding portion 211 further drives the abutting portion 212 to compress the elastic member 20 to move; On the one hand, the restoring force of the elastic member 20 pushes the contact portion 212 to move, drives the sliding portion 211 to move, and further drives the hook portion 213 to move.

Further, the bracket groove is also provided with a snap stopper 25 , which restricts the sliding portion 211 along the movement direction of the dust bag after the snapper assembly 16 is assembled into the groove, that is, the snap stopper 25 Only the sliding portion 211 is allowed to displace in a direction extending and contracting with the elastic member 20 .

The groove also includes a snap-fastening fixing wall 24 , which is used to limit the movement stroke of the snap-fastening assembly 16 . When the abutting portion 212 contacts with the snap-fastening fixing wall 24 , the hook portion 213 is connected to the snap-lock on the outer card board 6 . The snap fit of the stop bar 8 does not affect the normal work.

In the actual use process, as shown in Figure 4, the user first rotates and fixes the bracket to the host, then installs the dust bag from the chute 22 of the bracket, and finally installs the dust bucket to the host; after cleaning, first open the bottom of the dust bucket.
