Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular, to a box body and a cleaning equipment having the same. Background Art

[0002] Cleaning equipment, such as a vacuum cleaner, a floor washer, etc., usually has a cleaning head for moving on a surface to be cleaned and an upright body connected to the cleaning head. A handle is provided on the body for a human hand to hold, so as to push the cleaning head to move on the surface to be cleaned through the handle.

[0003] A negative pressure generating device for generating negative pressure is usually provided inside the body. The negative pressure generating device may include, for example, a motor and a fan driven by the motor. The fan is rotated by the motor to generate negative pressure. The cleaning head is provided with a suction port facing the surface to be cleaned, and the suction port is communicated with the negative pressure generating device. Dirt such as sewage, debris, and hair on the surface to be cleaned is sucked into the box body inside the body by the suction force generated by the negative pressure generating device.

[0004] Since the body and the box body inside it often need to be tilted and swung during the use of the cleaning equipment to adjust the angle, the fluid inside the box body will slosh and splash inside the box. This makes it easy for the fluid to be sucked into the negative pressure generating device from the main suction port communicated with the negative pressure generating device on the box body, thus damaging the motor.

[0005] Currently, to solve the above problems, usually the effective volume of the box body is actively reduced. That is, a liquid level sensor, such as an electrode plate, is provided on the box body. When the liquid level exceeds the two electrode plates, the two electrode plates are conducted. In this way, the liquid level can be detected by whether the electrode plates are conducted to realize liquid full alarm. This can reduce the liquid level height when the liquid is full and reduce the phenomenon that the liquid is sucked into the motor caused by the machine tilting and shaking. The defect of the above solution is that the utilization degree of the box body is not sufficient enough, resulting in more frequent cleaning of the box body, inconvenient use, and there is still a risk that the fluid is sucked into the main suction port when the shaking is relatively severe.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0047] Embodiment 1

[0048] Please refer to Figures 1 to 4 As shown, the present invention provides a box body, including: a box body 100, a partition member 200, and a fluid pipeline M. Among them, the box body 100 is hollow inside and has an open top. The partition member 200 is disposed in the hollow cavity of the box body 100, and the partition member 200 divides the hollow cavity of the box body 100 into a first chamber 110 and a second chamber 120 that are distributed up and down.

[0049] A box cover assembly 400 is detachably disposed at the open top of the box body 100. Please refer to Figure 13 As shown, a suction port 411 is provided on the box cover assembly 400, and the suction port 411 is communicated with a first negative pressure generating device to form a negative pressure in the first chamber 110.

[0050] The fluid pipeline M is disposed on the box body 100 and is communicated with the first chamber 110. The fluid pipeline M has a fluid discharge port M 口 , and the fluid discharge port M 口 is located in the first chamber 110. Under the action of the negative pressure in the first chamber 110, the fluid pipeline M can suck external fluid into the first chamber 110.

[0051] The above-mentioned fluid refers to a solid-liquid mixture. In a schematic scenario, the above-mentioned fluid is a mixture of dirt and sewage collected by a cleaning device when performing a cleaning task. It can be understood that the above-mentioned fluid includes, but is not limited to, a mixture of dirt and sewage collected by a cleaning device, and can also be a solid-liquid mixture generated or collected by other devices.

[0052] The fluid pipeline M can be disposed inside the box body 100 or outside the box body 100, as long as it is ensured that the fluid discharge port M口 Located in the first chamber 110. In one embodiment, please continue to refer to Figure 3 As shown, the fluid pipeline M is accommodated inside the box body 100, wherein the upper part of the fluid pipeline M is accommodated in the first chamber 110, and the lower part of the fluid pipeline M is accommodated in the second chamber 120, which has the advantages of compact structure and elegant appearance.

[0053] In this invention, please refer to Figure 5 and Figure 6 As shown, the separator 200 is provided with at least one filter hole 210, and the first chamber 110 and the second chamber 120 are connected through the filter hole 210. The fluid enters the first chamber 110 through the fluid pipe M. The solid medium in the fluid is separated and contained in the first chamber 110 by the separator 200, and the liquid medium in the fluid enters the second chamber 120 through the filter hole 210, thereby achieving automatic separation of the solid medium and the liquid medium in the fluid.

[0054] See also Figure 4 As shown, a guide tube 290 is further provided at the filter hole 210, and the guide tube 290 is located in the second chamber 120. The guide tube 290 is used to guide the liquid medium in the first chamber 110 to flow into the second chamber 120. The guide tube 290 is coaxially arranged with the filter hole 210, or approximately coaxially arranged.

[0055] When the fluid enters the first chamber 110 through the fluid pipe M, due to the upper and lower distribution of the first chamber 110 and the second chamber 120, the filter holes 210 can accommodate the solid medium in the fluid in the first chamber 110, and allow the liquid medium in the fluid to enter the second chamber 120 through the filter holes 210 under the action of its own gravity, thereby achieving separation of the solid medium and the liquid medium.

[0056] To sum up, the advantages of the partition 200 dividing the hollow cavity of the box body 100 into the first chamber 110 and the second chamber 120 distributed upper and lower are: on the one hand, it realizes the separation of solid medium and liquid medium, avoiding manual separation by the user; on the other hand, the second chamber 120 is a separate cavity and has no direct connection with the suction port 411. When the box body 100 shakes under the influence of the external environment, the liquid medium in the second chamber 120 cannot enter the first negative pressure generating device through the suction port 411, which greatly reduces the risk of the liquid medium being accidentally inhaled by the suction port 411 due to splashing; on the other hand, there is no need to set a liquid level detection unit inside the second chamber 120, which effectively increases the liquid medium storage capacity of the second chamber 120, thereby solving the pain point of frequently cleaning the box.

[0057] Considering that after the solid medium in the first chamber 110 is fully loaded or the liquid medium in the second chamber 120 is fully loaded, it is necessary to clean the solid medium and liquid medium in the box body 100. In the present invention, the partition 200 is connected below the box cover assembly 400. After the partition 200 and the box cover assembly 400 form an integral body, they can be detachably connected to the box body 100 together. Thus, when the solid medium in the first chamber 110 is fully loaded or the liquid medium in the second chamber 120 is fully loaded, an upward pulling force is applied to the box cover assembly 400, and the box cover assembly 400 together with the partition 200 is pulled out of the box body 100. During the upward movement of the partition 200, the solid medium in the first chamber 110 can be taken out of the first chamber 110, and the liquid medium in the second chamber 120 can be cleaned by pouring the box body 100, which has the advantages of simple structure and convenient use.

[0058] In the present invention, the partition 200 is inclined relative to the horizontal plane, which helps the liquid in the first chamber 110 to converge at the filter holes 210. The partition 200 is in the shape of a plate, and the shape of the partition 200 is the same as the cross-sectional shape of the box body 100. The above cross-section refers to the section obtained by a plane perpendicular to the axis direction of the box body 100.

[0059] In order to improve the sealing performance between the partition 200 and the box side wall of the box body 100, a first sealing member 500 is also provided at the edge of the partition 200, and the first sealing member 500 is made of a flexible material. Please refer to Figure 3 and Figure 12 As shown, the first sealing member 500 is in the shape of an integral ring and covers the edge of the partition 200. An annular groove 510 matching the edge of the partition 200 is provided on the inner ring of the first sealing member 500, and the first sealing member 500 is tensioned at the edge of the partition 200 through the above annular groove 510. [[ID=!1]]

[0060] In order to enable the liquid medium in the fluid entering the first chamber 110 to better flow into the lower second chamber 120 to achieve a more ideal solid-liquid separation effect. In the present invention, the box body further includes a second negative pressure generating device 121, and the second negative pressure generating device 121 is arranged inside the box body 100. The function of the second negative pressure generating device 121 is to generate negative pressure in the second chamber 120, and the negative pressure has a suction effect on the fluid in the first chamber 110. Thus, the liquid medium in the fluid in the first chamber 110 flows into the second chamber 120 under the dual action of its own gravity and the above suction force, effectively improving the solid-liquid separation effect.

[0061] In this embodiment, please refer to Figure 3 、 Figure 5 and Figure 6As shown, the second negative pressure generating device 121 is an air duct disposed in the first chamber 110. The second chamber 120 is communicated with the fluid pipeline M through the second negative pressure generating device 121, so as to form a negative pressure in the second chamber 120. Wherein, the partition member 200 is provided with a suction hole 240 for communicating the second chamber 120 with one end of the second negative pressure generating device, and the other end of the second negative pressure generating device 121 is connected to the side wall of the fluid pipeline M.

[0062] In order to make it easier to form a negative pressure in the second chamber 120, the cross-section of the second negative pressure generating device 121 is smaller than the cross-section of the fluid pipeline M. The above cross-section is the section obtained by a plane perpendicular to the pipeline axis direction. Thus, a Venturi effect can be formed between the second negative pressure generating device 121 and the fluid pipeline M. The fluid in the fluid pipeline M will promote the formation of a negative pressure in the second negative pressure generating device 121 during the high-speed flow process, so as to promote the formation of a negative pressure in the second chamber 120.

[0063] In the present invention, please refer to Figure 3 and Figure 6 As shown, the fluid pipeline M includes a first pipeline M1 disposed in the first chamber 110 and communicated with the first chamber 110 and a second pipeline M2 disposed in the second chamber 120. Wherein, the partition member 200 is provided with a connection port 220 for communicating the first pipeline M1 and the second pipeline M2, and the other end of the second negative pressure generating device 121 is communicated with the above first pipeline M1. The purpose of the up-and-down split setting of the fluid pipeline M is for convenient disassembly and assembly.

[0064] The bottom end of the first pipeline M1 close to the partition member 200 is disposed at the connection port 220, and the top end of the first pipeline M1 far from the partition member 200 is provided with the above fluid discharge port M 口 . The first pipeline M1 and the second negative pressure generating device 121 can be separately provided or integrally provided. For the purpose of reducing the number of parts, reducing the sealing structure and facilitating installation, preferably, the first pipeline M1 and the second negative pressure generating device 121 are integrally provided.

[0065] In the present invention, please continue to refer to Figure 6 As shown, the partition member 200 is provided with an installation portion 250 for cooperating with the first pipeline M1 and the second negative pressure generating device 121, and the bottom of the first pipeline M1 and the second negative pressure generating device 121 is provided with a cooperating portion 260 for cooperating with the installation portion 250. One of the installation portion 250 and the cooperating portion 260 is a groove, and the other is a boss. The above installation portion 250 and the cooperating portion 260 have the functions of installation positioning and increasing the sealing effect.

[0066] During installation, the installation and positioning of the first pipeline M1 and the second negative pressure generating device 121 are achieved through the installation part 250 and the mating part 260. Then, the first pipeline M1 and the second negative pressure generating device 121 are fixed on the partition 200 by bolts or screws. Specifically, the first pipeline M1 and the second negative pressure generating device 121 are provided with a first connection part 270 for mating with bolts or screws, and the first connection part 270 is provided with holes for the bolts or screws to screw into. The partition 200 is provided with through holes 280 corresponding to the first connection part 270 one by one, and the bolts or screws pass through the through holes 280 and then screw into the first connection part 270.

[0067] It can be understood that the partition 200, the first pipeline M1 and the second negative pressure generating device 121 can also be integrally formed. When specifically selecting the connection method between the partition 200, the first pipeline M1 and the second negative pressure generating device 121, it can be determined according to the specific implementation environment.

[0068] In the present invention, the top end of the second pipeline M2 close to the partition 200 is connected to the connection port 220, and the bottom end of the second pipeline M2 far from the partition 200 is arranged at the bottom of the box body 100. Among them, the bottom of the box body 100 is provided with a through hole for the bottom end of the second pipeline M2 to pass through.

[0069] Furthermore, the top end of the second pipeline M2 close to the partition 200 is detachably connected to the partition 200. At the connection port 220 of the partition 200, there is a plug-in structure 230 located in the second chamber 120, and the plug-in structure 230 is arranged on the bottom end surface of the partition 200. The top end of the second pipeline M2 close to the partition 200 is in plug-in fit with the plug-in structure 230.

[0070] Please continue to refer to Figure 4 As shown, the above-mentioned plug-in structure 230 is an annular rib plate arranged around the outer circumference of the connection port 220, and the top end of the second pipeline M2 close to the partition 200 is in the shape of a hollow cylinder. During installation, the bottom end of the second pipeline M2 far from the partition 200 is fixed at the bottom of the box body 100, and the top end of the second pipeline M2 close to the partition 2(0) is inserted into the plug-in structure 230 to achieve the installation of the second pipeline M2, which has the advantages of simple structure and convenient installation. ]>

[0071] Please continue to refer to Figure 3As shown, a second seal 600 is provided between the first pipe M1 and the second pipe M2, and the second seal 600 is provided on one of the plugging structure 230 and the second pipe M2. The second seal 600 is configured to form an end face seal between the first pipe M1 and the second pipe M2. The second seal 600 is a sealing ring, and the second seal 600 can achieve the seal between the second pipe M2 and the separator 200, preventing the fluid in the second pipe M2 from entering the second chamber 120.

[0072] In the present invention, the second pipe M2 and the second chamber 120 are independent of each other. The above-mentioned independence means that the second pipe M2 and the second chamber 120 are not directly connected. The fluid in the second pipe M2 enters the first chamber 110 after passing through the first pipe M1. Among them, the solid medium in the fluid in the first chamber 110 is retained in the first chamber 110, while the liquid medium in the fluid passes through the filtering holes 210 and enters the second chamber 120.

[0073] Considering that when there are solid media in the fluid with a particle size smaller than the aperture of the filtering holes 210, the above-mentioned particles can directly pass through the filtering holes 210 and enter the second chamber 120. To avoid the occurrence of the above situation, a second filter element 300 is provided in the first chamber 110, and a number of holes 310 are provided on the second filter element 300.

[0074] Different forms of the second filter element 300 have different requirements for the installation position. In the present invention, the setting methods of the second filter element 300 are as follows: First, the second filter element 300 is provided at the filtering holes 210; Second, the second filter element 300 is provided at the fluid discharge port M 口 .

[0075] When the second filter element 300 is provided at the filtering holes 210, the second filter element 300 is a filter net or a filter cartridge. Please refer to Figures 5 to 8 shown. The difference between the filter net and the filter cartridge lies in the difference in the size in the height direction (up and down direction). The material of the filter net or the filter cartridge can be stainless steel, plastic or other materials.

[0076] When the second filter element 300 is provided at the fluid discharge port M 口 . In this case, the second filter element 300 is a filter bag. The above-mentioned filter bag can be a bag body made of nylon texture, a bag body made of cotton thread texture, or a bag body made of other materials.

[0077] Specifically, when the second filter element 300 is a filter net, the size of the area covered by the second filter element 300 is determined according to the number of the filtering holes 210. Please refer to Figure 7As shown, when the number of the filtering holes 210 is large, the second filter element 300 is a whole-piece rigid filter net covering above all the filtering holes 210. When the number of the filtering holes 210 is small (the number of the filtering holes 210 is less than 3), the second filter element 300 is arranged in one-to-one correspondence with the filtering holes 210, Figure 8 is a schematic diagram of the setting position of the second filter element 300 when the number of the filtering holes 210 is one.

[0078] Please refer to Figure 5 and Figure 6 As shown, when the second filter element 300 is a filter cylinder, the second filter element 300 is arranged with a hollow interior, and the bottom of the second filter element 300 is open or both the bottom and the side wall are open. The filter cylinder-shaped second filter element 300 has a certain height in the up-and-down direction, and can effectively prevent the solid medium in the first chamber 110 from blocking the second filter element 300, and has the advantages of convenient use and good filtering effect.

[0079] Attached Figure 10 in, the second filter element 300 is in a cylindrical shape with a hollow interior and an open bottom, and the second filter element 300 covers above the filtering holes 210. Attached Figure 11 in, the second filter element 300 is in a tubular shape with a hollow interior and openings at the bottom and the side wall, the second filter element 300 covers above the filtering holes 210, and the side wall opening of the second filter element 300 abuts against the chamber wall of the first chamber 110.

[0080] Please refer to Figure 9 As shown, when the second filter element 300 is a filter bag, the bag body of the second filter element 300 is received in the first chamber 110, and the bag mouth of the second filter element 300 is communicated with the fluid discharge port M 口 and is detachably arranged at the fluid discharge port M 口 When the fluid enters the second filter element 300 through the fluid discharge port M 口 the solid medium in the fluid is retained in the bag body of the second filter element 300, and the liquid medium in the fluid can flow out of the second filter element 300 through the holes 310 on the second filter element 300. Finally, the liquid medium is converged in the second chamber 120.

[0081] The bag mouth of the second filter element 300 and the fluid discharge port M 口 adopt a detachable connection method for the purpose of facilitating the cleaning of the solid medium in the filter bag and avoiding the excessive solid medium in the second filter element 300 from affecting the discharge of the fluid from the fluid discharge port M 口 discharging.

[0082] In the present invention, please refer to Figure 13As shown, the lid assembly 400 includes a lid body 410 disposed at the top opening of the box body 100 and a lid bracket 420 fixedly disposed at the bottom of the lid body 410 and located within the first chamber 110. Among them, the separator 200 is detachably disposed at the bottom of the lid bracket 420.

[0083] The lid body 410 is provided with the above-mentioned suction port 411, and a HEPA 430 is provided at the suction port 411. The HEPA 430 functions to filter solid media and prevent solid media from entering the first negative pressure generating device through the suction port 411.

[0084] In the present invention, the fluid discharge port M 口 is disposed facing the top of the first chamber 110. When the fluid discharges from the fluid discharge port M 口 it is very easy to splash within the first chamber 110. In order to avoid increasing the risk of the fluid being accidentally sucked into the suction port 411 due to the splash of the fluid within the first chamber 110, a diversion structure is provided at the top of the first chamber 110, and the diversion structure covers the outer peripheral side of the fluid discharge port M 口

[0085] Please refer to Figure 14 and Figure 15 As shown, the diversion structure is disposed on the lid bracket 420. The lid bracket 420 includes a top plate 424 fixedly disposed at the bottom of the lid body 410 and a baffle 422 fixedly disposed on the top plate 424 and located below the top plate 424. Among them, the top plate 424 and the baffle 422 enclose to form the above-mentioned diversion structure.

[0086] The diversion structure is a diversion cavity with an open bottom. The fluid discharge port M 口 is disposed higher than the bottom end surface of the diversion cavity so that the fluid discharge port M 口 is located within the diversion cavity. Thus, the diversion cavity can have a good constraining effect on the fluid discharged through the fluid discharge port M 口 In the present invention, when the fluid discharges from the fluid discharge port M 口 after discharging, the liquid medium and solid medium in the fluid fall downward under the action of the diversion cavity, and the gas goes upward after discharging from the fluid discharge port M 口

[0087] Furthermore, the area of the top of the diversion cavity facing the fluid discharge port M 口 is an arc surface so that the fluid ejected through the fluid discharge port M 口 flows along the arc surface to the side cavity wall of the diversion cavity. Among them, there is a curved surface transition between the arc surface and the side cavity wall of the diversion cavity, and the side cavity wall of the diversion cavity extends in the direction from the first chamber 110 to the second chamber 120.

[0088] ​​The arc faces downward and is convexly provided to form a convex platform 4241 for guiding the flow. The above convex platform 4241 can form the Coanda effect in the flow guiding cavity, and both liquid media and gas media will flow along the cavity wall of the flow guiding cavity. If the above convex platform 4241 is not provided and the cavity top of the flow guiding cavity is a straight plane, the fluid discharge port M 口 The potential energy of the discharged fluid after the normal impact is relatively large, which easily causes the liquid medium in the fluid to be scattered and very fine, forming suspended liquid particles (water droplets). The suspended liquid particles may not flow down along the baffle 422. In this way, the suspended liquid particles are easily directly sucked away by the first negative pressure generating device. By providing the convex platform 4241, the fluid discharge port M 口 The discharged fluid is easy to form large-quality liquid particles, and the large-quality liquid particles flow down along the baffle 422, thereby promoting gas-liquid separation.

[0089] In the present invention, the fluid discharge port M 口 and the suction port 411 form an air flow channel. A first filter element 423 located on the air flow path is provided in the first chamber 110. A plurality of hollow holes 4231 are provided on the first filter element 423. The first filter element 423 is used to prevent solid media and liquid media in the fluid discharged from the fluid discharge port M 口 from entering the suction port 411 along with the air flow.

[0090] Furthermore, the first filter element 423 is provided on the top plate 424 and is located on the outer periphery of the baffle 422. The bottom edge of the first filter element 423 is set lower than the bottom edge of the baffle 422, and the bottom edge of the first filter element 423 abuts against the partition member 200. A second connecting portion 4232 is provided at the bottom of the first filter element 423, and the partition member 200 is detachably provided below the first filter element 423 through the above second connecting portion 4232.

[0091] In the present invention, the cross-sections of the first filter element 423 and the baffle 422 are both in a "U" shape. The above cross-section refers to the section obtained by a plane perpendicular to the axial direction of the box body 100. The opening directions of the first filter element 423 and the baffle 422 are the same. The openings of the first filter element 423 and the baffle 422 refer to the openings of the "U" shape.

[0092] Furthermore, please refer to Figure 16As shown, an extension channel 421 communicating with the suction port 411 is further provided at the top of the first filter element 423. An inlet 4211 is formed in the upper part of the lateral wall surface of the first filter element 423 for the extension channel 421. The air flow in the first chamber 110 flows to the suction port 411 via the extension channel 421 after passing through the first filter element 423. Among them, the bottom surface of the extension channel 421 is a smooth curved surface, and the smooth curved surface helps to improve the suction power (efficiency) of the first negative pressure generating device.

[0093] In the present invention, the inlet 4211 and the open end of the first filter element 423 are arranged back to back. The intention of such an arrangement is to reduce the risk that the liquid medium splashing in the first chamber 110 is accidentally sucked into the suction port 411.

[0094] Embodiment 2

[0095] The difference between this embodiment and Embodiment 1 lies in that the way of generating negative pressure in the second chamber 120 is different. In this embodiment, please refer to Figure 17 and Figure 18 As shown, the second chamber 120 is communicated with the first chamber 110 through a second negative pressure generating device 121, so that a negative pressure is formed in the second chamber 120.

[0096] Specifically, the second negative pressure generating device 121 extends along the direction from the second chamber 120 to the first chamber 110, and the other end of the second negative pressure generating device 121 is a free end.

[0097] Embodiment 3

[0098] The present invention further provides a cleaning device, including a body (not shown in the figure) and a box body provided on the body.

[0099] Please refer to Figure 2 、 Figure 3 and Figure 19As shown in the figure, the above locking structure includes a lock block 440 that is floatingly arranged on the lid body 410 of the lid assembly 400 in the up and down direction. A locking tongue 441 is provided at the top of the lock block 440. Among them, a spring 450 is built into the lid body 410, and the lock block 440 is floatingly arranged on the lid body 410 through the spring 450. The locking tongue 441 has a first position inside the lid body 410 and a second position where at least a part is outside the lid body 410. A lock port (not shown in the figure) that cooperates with the upper locking tongue 441 is provided on the fuselage. When the locking tongue 441 is in the second position, the locking tongue 441 is inserted into the lock port, thereby realizing the connection between the box body and the fuselage.

[0100] When a downward pressure is applied to the lock block 440, the lock block 440 moves downward and drives the locking tongue 441 to move downward together. At this time, the locking tongue 441 disengages from the lock port, and the box body can be removed from the fuselage, which has the advantage of being convenient for disassembly and assembly.

[0101] Furthermore, a holding part 130 is provided on the outer side wall of the box body. The holding part 130 is used for the user to hold.
