Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure.

In the related art, some filtering devices equipped in the floor sweeping robot generally include a layer of filtering teeth provided in a mop cleaning tray and a layer of filtering net provided in a sewage tank. However, such a filter arrangement still tends to cause clogging or even damage to the pump or sewer pipe delivering the sewage into the sewer tank due to the poor filtering effect of the single layer of filter teeth in the mop cleaning tray. Still other filtering devices equipped in sweeping robots include a filter mesh injection molded directly into the mop cleaning pan. This filter structure is costly and has a low filtration efficiency, which in turn results in a low sewage discharge efficiency. Therefore, it is necessary to provide a filter device having a good filtering effect and a high filtering efficiency.

In this regard, an embodiment of the present utility model provides a filter device, as shown in fig. 1, which includes a first filter layer 1 and a second filter layer 2. Wherein the first filter layer 1 and the second filter layer 2 are arranged in sequence in the flow direction F of the fluid to be filtered.

The first filter layer 1 includes a plurality of first filter teeth 11, the second filter layer 2 includes a plurality of second filter teeth 21, and a width d1 of a first tooth slot 12 between adjacent two of the first filter teeth 11 is larger than a width d2 of a second tooth slot 22 between adjacent two of the second filter teeth 21.

According to the filtering device provided by the utility model, the double filter layers which are sequentially arranged along the flowing direction F of the fluid to be filtered are adopted, and the widths of tooth grooves in the double filter layers are different, so that the first filter layer 1 of the outer layer contacts the fluid to be filtered before the second filter layer 2, impurities with larger sizes in the fluid to be filtered can be filtered, and the second filter layer 2 of the inner layer can filter impurities with smaller sizes in the fluid to be filtered, so that the filtering effect is effectively improved.

In addition, compared with the injection molding filter screen used in the related art, the filtering device provided by the utility model has the advantages that the filtering is performed by the filter tooth structure, the cost is low, the cleaning is easy, and the filtering efficiency is high. That is, the filtering device provided by the utility model can effectively filter impurities in the fluid to be filtered under the condition that the pollution discharge efficiency is not affected.

In this embodiment, the fluid to be filtered may be a liquid, such as sewage generated by cleaning a mop by a cleaning robot. Alternatively, the fluid to be filtered may be a gas.

The fluid to be filtered can flow from a plurality of directions to the first filter layer 1 and the second filter layer 2. As shown in fig. 1, the first filter layer 1 and the second filter layer 2 may be curved as a whole, so that the fluid to be filtered flowing in a plurality of directions can be sufficiently filtered. In other embodiments, the first filter layer 1 and the second filter layer 2 may be linear as a whole.

In the present embodiment, the width at each position in the first tooth slot 12 (the second tooth slot 22) may be substantially uniform. In other embodiments, the width of the first gullet 12 (second gullet 22) at each location may be different, in which case a width of the first gullet 12 greater than a width of the second gullet 22 may be understood as: the maximum width of the first gullet 12 is greater than the maximum width of the second gullet 22.

Alternatively, as shown in FIG. 1, the depth h1 of the first gullet 12 may be greater than the depth h2 of the second gullet 22. The filtering layer with the filtering tooth structure is adopted, and the filtering precision depends on the size of a gap between the filtering teeth, namely the area of a tooth slot. In addition to controlling the width d1 of the first tooth groove 12 to be greater than the width d2 of the second tooth groove 22, the depth h1 of the first tooth groove 12 is controlled to be greater than the depth h2 of the second tooth groove 22, and the filtering precision of the first filtering layer 1 and the second filtering layer 2 can be further differentiated, so that the filtering effect of the filtering device is improved.

In this embodiment, to facilitate processing of the first filter layer 1 and the second filter layer 2, the tooth thickness of the first filter teeth 11 may be substantially the same as the width of the first tooth grooves 12. Similarly, the tooth thickness of the second filter tooth 21 may be approximately the same as the width of the second tooth slot 22. Also, the size of the plurality of first filter teeth 11 and the interval between adjacent two first filter teeth 11 (i.e., the width of the first tooth groove 12) may each be substantially uniform. Similarly, the size of the plurality of second filter teeth 21 and the spacing between adjacent two second filter teeth 21 (i.e., the width of the second gullet 22) may each be substantially uniform.

Alternatively, as shown in fig. 2, the orthographic projection of the first tooth slot 12 on the setting plane is at least partially overlapped with the orthographic projection of the second filter tooth 21 on the setting plane, and the setting plane is perpendicular to the tooth width direction W of the second filter tooth 21. In other words, the first filter teeth 11 and the second filter teeth 21 may be staggered.

After the fluid to be filtered is coarsely filtered through the first filter teeth 11, a portion of the impurities having a smaller size may not be filtered so as to be carried by the fluid to be filtered through the first tooth grooves 12. The fluid passing through the first tooth groove 12 may be intercepted by the second filter tooth 21 provided corresponding to the first tooth groove 12 to be split, so that the foreign substances carried in the fluid are filtered by the second filter tooth 21.

The tooth width direction W is shown in fig. 1 and 6, and is perpendicular to the depth direction of the first tooth groove 12 (second tooth groove 22) and perpendicular to the tooth thickness direction of the first filter tooth 11 (second filter tooth 21). In some embodiments, the tooth width direction W is parallel to the flow direction F of the fluid to be filtered.

Alternatively, as shown in fig. 3, the orthographic projection of the first tooth slot 12 on the setting plane may cover the orthographic projection of the second filter tooth 21 on the setting plane. Alternatively, the orthographic projection of the second filter tooth 21 on the setting plane may cover the orthographic projection of the first tooth slot 12 on the setting plane. By disposing the first tooth grooves 12 and the second filter teeth 21 in a facing relationship, the filtering effect of the filter device can be further improved.

Alternatively, as shown in fig. 3, the first tooth tip 111 of the first filter tooth 11 may be in the same positioning plane as the second tooth tip 211 of the second filter tooth 21, which is parallel to the tooth width direction W of the second filter tooth 21.

In some embodiments, the filter device may be used in combination with other structures (e.g., a water deflector). The water guard may overlap the tooth top sides of the first and second filter teeth 11 and 21 to restrict the flow of fluid to be filtered through the first and second tooth slots 12 and 22. In this case, the first filter tooth 11 and the second filter tooth 21 are set to be flush with the tooth tops, so that the gap between the filter device and the water baffle can be minimized, the filtering effect can be improved, and the water baffle can be conveniently assembled.

Alternatively, as shown in fig. 5, the first bottom surface 121 of the first tooth slot 12 may include a first arcuate surface 1211, the first arcuate surface 1211 being contiguous with the first side surface 122 of the first tooth slot 12, and the first arcuate surface 1211 may be recessed away from the first opening 123 of the first tooth slot 12, the first opening 123 being opposite the first bottom surface 121.

In this embodiment, the first bottom 121 in the first tooth slot 12 is connected with the first side 122 through the arc surface, so that a dead angle formed at the connection position of the first bottom 121 and the first side 122 can be avoided, and the cleaning efficiency of the filtering device is affected.

The second gullet 22 may be arranged similarly to the first gullet 12. That is, the second bottom surface 221 of the second tooth slot 22 may include a second arcuate surface 2211, the second arcuate surface 2211 is connected with the second side surface 222 of the second tooth slot 22, and the second arcuate surface 2211 is recessed away from the second opening 223 of the second tooth slot 22, and the second opening 223 is opposite to the second bottom surface 221.

As can be seen from fig. 5, the tooth height of the first filter tooth 11 can be slightly less than the depth h1 of the first tooth slot 12 due to the arrangement of the first arcuate surface 1211 described above. Correspondingly, the tooth height of the second filter tooth 21 may be slightly smaller than the depth h2 of the second tooth slot 22.

Optionally, as shown in fig. 7, the filtering device may further comprise a baffle 3. The baffle 3 may be connected to the end of the first filter layer 1 and the end of the second filter layer 2, and the first filter layer 1, the second filter layer 2 and the baffle 3 surround to form a receiving chamber 4. The fluid to be filtered flows from the first filter layer 1 via the receiving chamber 4 to the second filter layer 2.

The receiving chamber 4 may be used to store impurities filtered out by the second filter layer 2. As described above, the fluid passing through the first tooth groove 12 is intercepted by the second filter tooth 21 provided corresponding to the first tooth groove 12 to be split, so that the foreign substances carried in the fluid are filtered by the second filter tooth 21. Impurities of smaller size, such as hair and flock, filtered by the second filter teeth 21, may be stored in the receiving chamber 4 formed around the first filter layer 1, the second filter layer 2 and the baffle 3. The user can regularly clean the receiving chamber 4.

In some embodiments, both side ends of the first filter layer 1 (or the second filter layer 2) may be blocked by an integrally formed single baffle 3. In other embodiments, as shown in fig. 7, the baffle 3 may include a first baffle 31 and a second baffle 32. Wherein the first baffle 31 may be connected to the first end of the first filter layer 1 and the first end of the second filter layer 2; the second baffle 32 may be connected to the second end of the first filter layer 1 and the second end of the second filter layer 2. The first filter layer 1, the second filter layer 2, the first baffle 31, and the second baffle 32 surround to form the accommodation chamber 4.

Alternatively, as shown in fig. 7, the outer side of the junction of the second filter layer 2 and the baffle 3 may be formed with a fitting surface 6. The fitting surface 6 may intersect with each of the second filter layer 2 and the baffle 3 at an obtuse angle.

As shown in fig. 7, the fitting surface 6 may be formed by cutting the outer side of the junction of the second filter layer 2 and the baffle 3 in a piece in the depth direction of the first tooth groove 12 (second tooth groove 22). That is, the fitting surface 6 may extend in the depth direction of the first tooth groove 12 (the second tooth groove 22). Other mating structures may be fitted into place with the filter device via the fitting surface 6.

The filter device may further comprise a reinforcement 5, which reinforcement 5 is located inside the junction of the second filter layer 2 and the baffle 3. That is, the reinforcing portion 5 may be located in the accommodating chamber 4. The exposed surface 51 of the reinforcing portion 5 may intersect with the second filter layer 2 and the baffle 3, respectively, and the included angles formed by the intersection are all obtuse angles, and the exposed surface 51 is a surface facing the first filter layer 1.

As shown in fig. 7, the reinforcement portion 5 may have a substantially triangular prism shape. And two side surfaces of the triangular prism shape are connected to the second filter layer 2 and the baffle plate 3, respectively, and the other side surface faces the first filter layer 1 as an exposed surface 51.

In some embodiments, the mounting surface 6 and the exposed face 51 of the reinforcement 5 may be substantially parallel. By providing the reinforcing portion 5, the strength of the junction of the second filter layer 2 and the baffle 3 can be enhanced, making up for the strength defect caused by the formation of the fitting surface 6. In addition, the reinforcing part 5 can avoid dead angles formed at the joint of the second filter layer 2 and the baffle plate 3, so that the filter device is convenient to clean.

Similarly, a reinforcing portion (which may be referred to as a second reinforcing portion) may be formed at the junction of the first filter layer 1 and the baffle 3. The exposed surface of the second reinforcement may be disposed opposite the exposed surface 51 of the reinforcement 5 (which may be referred to as a first reinforcement).

In some embodiments, where space conditions allow and have higher filtration requirements, the number of filtration layers may be further increased and the filtration accuracy of each filtration layer controlled.

Optionally, as shown in fig. 8, the filter device further comprises a third filter layer 7, the third filter layer 7 comprising a plurality of third filter teeth 71. Wherein the third filter layer 7 is located between the first filter layer 1 and the second filter layer 2 and the width d3 of the third tooth slot 72 between two adjacent third filter teeth 71 is smaller than the width d1 of the first tooth slot 12 and larger than the width d2 of the second tooth slot 22.

In fig. 8, the number of third filter layers 7 is exemplified as one. In other embodiments, the filter device may comprise two or more third filter layers 7. And the filtration accuracy of the plurality of third filter layers 7 arranged in order becomes gradually larger in the direction from the first filter layer 1 toward the second filter layer 2. In other words, the width of the third tooth slot 72 gradually decreases.

The embodiment of the application also provides a sweeping robot, which is provided with the filtering device.

In some embodiments, the sweeping robot may comprise a base station and a mobile part, wherein the base station may comprise a mop cleaning tray as described in fig. 9, and the above-described filtering device may be used as a part of the mop cleaning tray.

In embodiments of the present utility model, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The term "plurality" refers to two or more, unless explicitly defined otherwise.
