Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, and specifically to cleaning equipment. Background Technology
[0002] Cleaning devices such as mite removers are used to clean dust and mites from household products and disinfect them, providing a more suitable environment. Mite removers use a vacuum motor to create negative pressure, sucking debris from the cleaning surface into a dust cup. When the vacuum motor is running, a large amount of air enters from the motor inlet and exits from the motor tail before exiting the machine. Because the air outlet area is smaller than the air inlet area, the air velocity is very high when it exits the machine from the motor tail. This high-speed air impacting the machine generates significant noise, resulting in a poor user experience.
[0003] Related technology discloses a cleaning device, including a main body with an inner cavity, in which a suction device for generating suction airflow is disposed. The suction device includes a fan body and a fan cover. The fan body is used to generate suction airflow and is disposed inside the fan cover. The fan body and the fan cover are spaced apart to form a return air cavity between the fan cover and the fan body. The suction device also includes a first sound-absorbing layer, through which the airflow generated by the fan body passes into the return air cavity. A first air outlet is disposed in the return air cavity. The fan cover also includes a sound-absorbing cavity, which is fluidly connected to the return air cavity through the first air outlet. A second sound-absorbing layer is disposed in the sound-absorbing cavity, through which the airflow passes and exits the fan cover. The main body also has an exhaust port, at which a third sound-absorbing layer is disposed, through which the airflow passes and exits the cleaning device.
[0004] In the aforementioned technologies, air first moves downwards, then backwards, and finally exits the machine body. By extending the exhaust path, the air movement speed is reduced. However, the design of the silencing cavity increases the overall length of the machine body, thereby increasing its volume. Utility Model Content
[0005] In view of this, the present invention provides a cleaning device to solve the problem of increased machine size caused by noise reduction in related technologies.
[0006] This utility model provides a cleaning device, including:
[0007] The fuselage has exhaust vents on both sides;
[0008] A vacuum motor assembly is disposed within the body and includes a motor housing and a motor. The motor is disposed within the motor housing. The motor housing includes a circumferential sidewall and a surrounding plate structure disposed outside the circumferential sidewall. A first air outlet space is formed between the circumferential sidewall and the motor. A second air outlet space is formed between the circumferential sidewall, the surrounding plate structure, and the body. An air outlet is provided on the circumferential sidewall. The air outlet is offset from the exhaust port. The air outlet connects the first air outlet space and the second air outlet space.
[0009] Beneficial effects: When the vacuum motor assembly is working, air enters the motor and flows from front to back. It then enters the first exhaust space between the circumferential sidewall and the motor, and subsequently enters the second exhaust space through the vent. Because the exhaust and vent are offset, the air does not flow directly from the exhaust vent after exiting the exhaust vent. Instead, it flows around the circumferential sidewall for a distance before exiting through the vent, lengthening the exhaust path and increasing resistance during airflow. This slows the airflow before it exits the unit, reducing noise and improving the user experience. Furthermore, since the second exhaust space is located on the outer periphery of the first exhaust space, the exhaust path is lengthened and airflow resistance is increased without increasing the overall size, thus reducing noise without increasing the overall volume.
[0010] In one optional embodiment, the motor housing includes a front motor housing and a rear motor housing, the motor is mounted on the front motor housing, and the air outlet is located on the front motor housing.
[0011] Beneficial effects: The motor housing includes a front motor housing and a rear motor housing. The motor is installed in the front motor housing. After the motor is installed, the rear motor housing is connected to the front motor housing, which facilitates the assembly of the vacuum motor assembly.
[0012] In one optional embodiment, the front housing of the motor includes a first rib, the rear housing of the motor includes a second rib, the first rib and the second rib constitute the circumferential sidewall, and the air outlet is disposed on the first rib.
[0013] Beneficial effects: The first and second ribs form a circumferential sidewall. The air outlet is located on the first rib. When the vacuum motor assembly is working, air enters the motor from the intake port of the front housing, flows out from the end outlet of the motor in a front-to-back direction, and then enters the air outlet gap between the end outlet of the motor and the rear housing of the motor. Since the air outlet is located on the first rib, the air needs to flow backward first and then forward to the first air outlet space, and then flow out of the motor housing through the air outlet. This achieves the extension of the exhaust path and the increase of air movement resistance without increasing the volume, thereby reducing noise without increasing the volume.
[0014] In one optional embodiment, one end of the first reinforcing bar and the second reinforcing bar is provided with a first reinforcing bar, and the other end of the first reinforcing bar and the second reinforcing bar is provided with a first double stop, and the first reinforcing bar is embedded in the first double stop.
[0015] Beneficial effect: By providing a first reinforcing bar at one end of the first reinforcing bar and the second reinforcing bar, and providing a first double stop at the other end of the first reinforcing bar and the second reinforcing bar, a sealed connection between the first reinforcing bar and the second reinforcing bar can be achieved.
[0016] In one optional embodiment, the enclosure structure includes a front connecting body disposed on the front housing of the motor, the front connecting body being disposed on the side of the first rib away from the second rib, the body being provided with one of a second rib and a second double stop, the bottom of the front connecting body being provided with the other of the second rib and the second double stop, the second rib being inserted into the second double stop.
[0017] Beneficial effects: The machine body is provided with one of the second rib and the second double stop, and the bottom of the front connecting body is provided with the other of the second rib and the second double stop. The second rib and the second double stop are inserted into each other, which facilitates the quick positioning and installation of the front housing of the motor and can achieve a seal between the front connecting body and the machine body.
[0018] In one optional embodiment, the top of the front connecting body is provided with a front eave, the front eave is located above the first surrounding rib, and the surrounding plate structure further includes a rear connecting body provided on the rear housing of the motor, the rear connecting body is provided on the side of the second surrounding rib away from the first surrounding rib, the top of the rear connecting body is provided with a rear eave, the rear eave is located above the second surrounding rib, and the front eave and the rear eave are sealed together.
[0019] Beneficial effects: The front eaves are located above the first rib, and the rear eaves are located above the second rib. The front and rear eaves are sealed together, which can seal the top of the vacuum motor assembly, prevent air from flowing out of the air outlet and flowing upward into the machine body, and ensure that the air can only flow out towards the exhaust outlet.
[0020] In one alternative embodiment, the front eaves are provided with one of a third rib and a third double stop, and the rear eaves are provided with the other of a third rib and a third double stop, wherein the third rib is inserted into the third double stop.
[0021] Beneficial effects: The front eaves are provided with one of the third ribs and the third double stop, and the rear eaves are provided with the other of the third ribs and the third double stop. The third ribs and the third double stop are interlocked, which facilitates the quick and easy sealing connection between the front eaves and the rear eaves.
[0022] In one optional embodiment, a first noise-reducing cotton is provided between the motor and the circumferential sidewall;
[0023] And / or, a second noise-reducing cotton is provided on the outer side of the motor housing, the second noise-reducing cotton at least surrounding the circumferential sidewall.
[0024] Beneficial effects: Because a first noise-reducing cotton is installed between the motor and the circumferential sidewall, air flowing from the motor end passes through this cotton before reaching the air outlet. This cotton not only reduces motor noise but also increases resistance during airflow, slowing the air down before it exits the unit, thus reducing noise and improving the user experience. A second noise-reducing cotton surrounds at least the circumferential sidewall of the motor housing. Air flowing from the outlet must pass through this cotton before reaching the exhaust vent, further increasing resistance and slowing the air down before it exits the unit, thus reducing noise and improving the user experience.
[0025] In one alternative embodiment, the vacuum motor assembly is sealed to the housing by a sealing assembly that prevents air from flowing from areas other than the second exhaust space to the exhaust port.
[0026] Beneficial effects: Since the vacuum motor assembly is sealed to the body through the sealing component, the sealing component prevents air from flowing to the exhaust port from areas other than the second air outlet space. Therefore, air can only enter the motor housing through the intake port and will not enter the body from other locations, nor will it be directly discharged from the exhaust port.
[0027] In one alternative embodiment, the housing includes an upper housing and a lower housing, and the sealing assembly includes a first seal disposed between the bottom of the vacuum motor assembly and the housing, and a second seal disposed between the two side edges of the vacuum motor assembly and the housing.
[0028] Beneficial effects: The first seal can seal the space between the bottom of the vacuum motor assembly and the body, and the second seal can seal the space between the two sides of the vacuum motor assembly and the body. The arrangement of the first and second seals can prevent air from flowing from areas other than the second air outlet space to the exhaust port. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0045] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0046] The following is combined Figures 1 to 10 The following describes embodiments of the present invention.
[0047] According to an embodiment of this utility model, a cleaning device is provided, including a body and a vacuum motor assembly. Exhaust vents 101 are provided on both sides of the body. The vacuum motor assembly is disposed within the body and includes a motor housing and a motor 3. The motor 3 is disposed within the motor housing, which includes a circumferential sidewall and a surrounding plate structure located outside the circumferential sidewall. A first air outlet space 4 is formed between the circumferential sidewall and the motor 3, and a second air outlet space is formed between the circumferential sidewall, the surrounding plate structure, and the body. The motor housing has an air outlet 603, which is offset from the exhaust vents 101 and connects the first and second air outlet spaces.
[0048] In this embodiment, when the vacuum motor assembly is operating, air enters the motor 3 and flows from front to back. It then enters the first exhaust space 4 between the circumferential sidewall and the motor 3, and subsequently enters the second exhaust space through the exhaust port 101. Because the exhaust port 603 and the exhaust port 101 are offset, the air flowing from the exhaust port 603 does not directly exit from the exhaust port 101. Instead, it flows around the circumferential sidewall for a distance before exiting from the exhaust port 101, extending the exhaust path and increasing resistance during airflow. This slows the air speed before it exits the machine body, thereby reducing noise and improving the user experience. Furthermore, since the second exhaust space is located on the outer periphery of the first exhaust space, the exhaust path is extended and the airflow resistance is increased without increasing the overall volume, thus reducing noise without increasing the overall size.
[0049] In one specific embodiment, the vacuum motor assembly is located between the exhaust vents 101 on both sides.
[0050] Specifically, a motor mounting cavity is formed inside the motor housing. One end of the motor housing is provided with an intake port 601 that communicates with the motor mounting cavity. The motor housing includes a circumferential sidewall, and an air outlet 603 is located on the circumferential sidewall near the intake port 601. The motor 3 is located inside the motor mounting cavity. An annular first air outlet space 4 is formed between the circumferential wall of the motor 3 and the circumferential sidewall. An air outlet gap 5 is formed between the end outlet 301 of the motor 3 and the motor housing. The air outlet gap 5 is located on the side of the first air outlet space 4 away from the intake port 601.
[0051] When the vacuum motor assembly is working, air enters the motor 3 through the intake port 601, such as... Figure 9 and Figure 10 The arrow indicates the direction. Air flows from the end outlet 301 of motor 3 in a front-to-back direction and enters the air outlet gap 5 between the end outlet 301 of motor 3 and the motor housing. Since the air outlet gap 5 is located on the side of the first air outlet space 4 away from the intake 601, the air needs to flow forward into the first air outlet space 4, and then out of the motor housing through the air outlet 603. Because the air outlet 603 is misaligned with the exhaust vent 101 of the body, the air flowing from the air outlet 603 does not flow directly out of the exhaust vent 101, but instead flows around the circumferential sidewall for a distance before exiting through the exhaust vent 101. This extends the exhaust path and increases resistance during airflow, making the air speed very slow before exiting the body, thereby reducing noise and improving the user experience. Furthermore, exhaust vents 101 are located on both sides of the body, and the vacuum motor assembly is positioned between the exhaust vents 101 on both sides. Therefore, without increasing the volume, the exhaust path is extended and the resistance to air movement is increased, thus reducing noise without increasing the volume.
[0052] In one embodiment, the motor housing includes a front motor housing 6 and a rear motor housing 7, with the motor 3 mounted on the front motor housing 6 and the air outlet 603 located on the front motor housing 6.
[0053] In this embodiment, the motor housing includes a front motor housing 6 and a rear motor housing 7. The motor 3 is installed in the front motor housing 6. After the motor 3 is installed, the rear motor housing 7 is connected to the front motor housing 6 to facilitate the assembly of the vacuum motor assembly.
[0054] In one embodiment not shown in the figure, the motor housing may be further divided into two half-shells, left and right, which are joined together, and the joining surfaces of the two half-shells are coplanar with the central axis surface of the motor 3.
[0055] Specifically in one embodiment, such as Figure 1 and Figure 2 As shown, the vacuum motor assembly also includes a sealing ring 8 and a shock-absorbing pad 9. The motor 3 and the front housing 6 of the motor are sealed by the sealing ring 8, and the shock-absorbing pad 9 is disposed between the end of the motor 3 and the rear housing 7 of the motor.
[0056] In one embodiment, such as Figure 3 and Figure 4 The front housing 6 of the motor includes a first rib 602, and the rear housing 7 of the motor includes a second rib 701. The first rib 602 and the second rib 701 form a circumferential sidewall. The circumferential sidewall and the motor 3 form a first air outlet space 4. The air outlet 603 is located on the first rib 602.
[0057] In this embodiment, the first rib 602 and the second rib 701 form a circumferential sidewall. The air outlet 603 is located on the first rib 602. When the vacuum motor assembly is working, air enters the motor 3 from the intake port 601 of the front housing 6 of the motor, flows out from the end outlet 301 of the motor 3 in a front-to-back direction, and enters the air outlet gap 5 between the end outlet 301 of the motor 3 and the rear housing 7 of the motor. Since the air outlet 603 is located on the first rib 602, the air needs to flow backward first and then forward to the first air outlet space 4. After that, it flows out of the motor housing through the air outlet 603. This achieves the extension of the exhaust path and the increase of air movement resistance without increasing the volume, thereby reducing noise without increasing the volume.
[0058] In one embodiment not shown in the figure, the front housing 6 of the motor may also include all the circumferential sidewalls, which are connected to the rear housing 7 of the motor.
[0059] In one embodiment, one end of the first reinforcing rib 602 and the second reinforcing rib 701 is provided with a first reinforcing bar 702, and the other end of the first reinforcing rib 602 and the second reinforcing rib 701 is provided with a first double stop 604, and the first reinforcing bar 702 is embedded in the first double stop 604.
[0060] In this embodiment, by providing a first rib 702 at one end of the first rib 602 and the second rib 701, and providing a first double stop 604 at the other end of the first rib 602 and the second rib 701, the first rib 702 can be embedded into the first double stop 604, thereby achieving a sealed connection between the first rib 602 and the second rib 701.
[0061] Specifically in one embodiment, such as Figure 3 As shown, the end of the first reinforcing bar 602 is provided with a first double stop 604, as... Figure 4 As shown, the end of the second reinforcing bar 701 is provided with a first reinforcing bar 702.
[0062] In one embodiment, the enclosure structure includes a front connecting body 605 disposed on the front housing 6 of the motor. The front connecting body 605 is disposed on the side of the first rib 602 away from the second rib 701. The body is provided with one of the second rib 201 and the second double stop 606. The bottom of the front connecting body 605 is provided with the other of the second rib 201 and the second double stop 606. The second rib 201 is inserted into the second double stop 606.
[0063] In this embodiment, the machine body is provided with one of the second rib 201 and the second double stop 606, and the bottom of the front connecting body 605 is provided with the other of the second rib 201 and the second double stop 606. The second rib 201 and the second double stop 606 are inserted into each other, which facilitates the quick positioning and installation of the motor front housing 6 and can achieve the sealing between the front connecting body 605 and the machine body.
[0064] In one specific embodiment, the fuselage is provided with a second rib 201, and the front connecting body 605 is provided with a second double stop 606.
[0065] In one specific embodiment, the fuselage includes an upper housing 1 and a lower housing 2, and a second rib 201 is disposed on the lower housing 2.
[0066] Specifically in one embodiment, such as Figure 3 and Figure 7 , Figure 8 As shown, the second rib 201 is arc-shaped, and the shape of the second double stop 606 is consistent with the shape of the second rib 201. When the second rib 201 and the second double stop 606 are inserted, the bottom of the motor front housing 6 is sealed with the body, and air will not pass through the bottom of the front connecting body 605, so that air can only enter the motor front housing 6 through the intake port 601.
[0067] Specifically in one embodiment, such as Figure 3 As shown, the air outlet 603 is located on the first rib 602 and is adjacent to the front connecting body 605.
[0068] In one embodiment, the front connecting body 605 has a front eave 607 at its top, which is located above the first surrounding rib 602. The enclosure structure also includes a rear connecting body 703 located on the rear housing 7 of the motor. The rear connecting body 703 is located on the side of the second surrounding rib 701 away from the first surrounding rib 602. The rear connecting body 703 has a rear eave 704 at its top, which is located above the second surrounding rib 701. The front eave 607 and the rear eave 704 are sealed together.
[0069] In this embodiment, the front eaves 607 are located above the first rib 602, and the rear eaves 704 are located above the second rib 701. The front eaves 607 and the rear eaves 704 are sealed together, which can seal the top of the vacuum motor assembly, prevent air from flowing out of the air outlet 603 and flowing upward into the machine body, and ensure that the air can only flow out towards the exhaust port 101.
[0070] In one embodiment, the front eaves 607 is provided with one of a third rib 608 and a third double stop 705, and the rear eaves 704 is provided with the other of a third rib 608 and a third double stop 705, wherein the third rib 608 is inserted into the third double stop 705.
[0071] In this embodiment, the front eaves 607 is provided with one of the third rib 608 and the third double stop 705, and the rear eaves 704 is provided with the other of the third rib 608 and the third double stop 705. The third rib 608 and the third double stop 705 are inserted together, which facilitates the quick and easy sealing connection between the front eaves 607 and the rear eaves 704.
[0072] Specifically in one embodiment, such as Figure 3 and Figure 4 As shown, the front eaves 607 are provided with a third rib 608, and the rear eaves 704 are provided with a third double stop 705. Both the front eaves 607 and the rear eaves 704 extend in the horizontal direction.
[0073] In one embodiment, the air outlet 603 is located at the top of the first rib 602.
[0074] In this embodiment, since the air outlet 603 is located at the top of the first rib 602 and the exhaust port 101 is located on the side of the body, the air has a longer flow path to the exhaust port 101 after flowing out of the air outlet 603, which further extends the exhaust path and increases the resistance to air movement.
[0075] In one embodiment, the front housing 6 and the rear housing 7 of the motor are connected by a snap-fit 609.
[0076] In this embodiment, the front housing 6 and the rear housing 7 of the motor are connected by a snap fastener 609, which can improve assembly efficiency. Furthermore, when the motor 3 malfunctions, the front housing 6 and the rear housing 7 can be quickly separated for easy maintenance.
[0077] In one embodiment, the first rib 602 is provided with a plurality of buckles 609 spaced apart along the circumference, and the second rib 701 is provided with a plurality of protruding ribs 706 spaced apart along the circumference, with the buckles 609 and the protruding ribs 706 corresponding to each other and engaging.
[0078] In this embodiment, the buckle 609 and the rib 706 are engaged one-to-one, which can quickly connect the front housing 6 of the motor and the rear housing 7 of the motor.
[0079] In one embodiment, the rib 706 is provided with limiting ribs 707 on both sides, and the buckle 609 is adapted to be limited between the two limiting ribs 707.
[0080] In this embodiment, the limiting rib 707 can limit the position of the buckle 609.
[0081] Specifically, the distance between the two limiting ribs 707 is slightly greater than the width of the buckle 609.
[0082] In one embodiment, a first noise-reducing cotton 10 is provided between the motor 3 and the circumferential sidewall; a second noise-reducing cotton 11 is provided on the outside of the motor housing, and the second noise-reducing cotton 11 at least surrounds the circumferential sidewall.
[0083] In this embodiment, since a first noise-reducing cotton 10 is provided between the motor 3 and the circumferential sidewall, air flowing out from the end of the motor 3 will pass through the first noise-reducing cotton 10 and flow to the air outlet 603. The first noise-reducing cotton 10 not only reduces the noise of the motor 3, but also increases the resistance during airflow, making the air speed very slow before exiting the body, thereby reducing noise and improving the user experience. The second noise-reducing cotton 11 at least surrounds the circumferential sidewall of the motor housing. After the air flows out from the air outlet 603, it needs to pass through the second noise-reducing cotton 11 during the process of flowing to the exhaust port 101, which further increases the resistance during airflow, making the air speed very slow before exiting the body, thereby reducing noise and improving the user experience.
[0084] It should be noted that the first noise-reducing cotton 10 has multiple small holes to allow air to pass through.
[0085] Specifically, the first noise-reducing cotton 10 is disposed between the peripheral wall of the motor 3 and the circumferential side wall of the motor housing, and is also disposed at the end outlet 301 of the motor 3.
[0086] In one embodiment, the vacuum motor assembly is sealed to the housing by a sealing component that prevents air from flowing from an area other than the second air outlet space to the exhaust port 101.
[0087] In this embodiment, since the vacuum motor assembly is sealed to the body by a sealing component, the sealing component prevents air from flowing from areas other than the second air outlet space to the exhaust port 101. Therefore, air can only enter the motor housing through the intake port 601 and will not enter the body from other locations, nor will it be directly discharged from the exhaust port 101.
[0088] In one embodiment, the housing includes an upper housing 1 and a lower housing 2, and the sealing assembly includes a first seal 12 disposed between the bottom of the vacuum motor assembly and the housing, and a second seal 13 disposed between the two side edges of the vacuum motor assembly and the housing.
[0089] In this embodiment, the first seal 12 can seal the space between the bottom of the vacuum motor assembly and the body, and the second sealing space can seal the space between the two side edges of the vacuum motor assembly and the body. The arrangement of the first seal 12 and the second seal 13 can prevent air from flowing from the area other than the second air outlet space to the exhaust port 101.
[0090] Specifically, the first sealing element 12 is a sealing gasket, and the second sealing element 13 is a sealing strip.
[0091] In one embodiment, the body includes an upper housing 1 and a lower housing 2, an exhaust port 101 is provided on both sides of the upper housing 1, a first sealing member 12 is provided between the bottom of the vacuum motor assembly and the lower housing 2, and a second sealing member 13 is provided between the two side edges of the vacuum motor assembly and the upper housing 1.
[0092] In this embodiment, the body includes an upper housing 1 and a lower housing 2, which facilitates the assembly of the vacuum motor assembly inside the body.
[0093] Specifically, the first seal 12 is installed on the lower housing 2, and the second seal 13 is installed on the inner side of the upper housing 1.
[0094] In one specific embodiment, the cleaning device is a mite remover.
[0095] In the cleaning device provided in this embodiment, when the vacuum motor assembly is working, air enters the motor 3 from the suction port 601, flows out from the end outlet 301 of the motor 3 in a front-to-back direction, and then enters the air outlet gap 5 between the end outlet 301 of the motor 3 and the motor housing. Since the air outlet gap 5 is located on the side of the first air outlet space 4 away from the suction port 601, the air needs to flow forward to the first air outlet space 4, and then flow out of the motor housing through the air outlet 603. Since the air outlet 603 is misaligned with the exhaust port 101 of the machine body, the air does not flow directly out of the exhaust port 101 after flowing out of the air outlet 603, but flows around the circumferential sidewall for a certain path before flowing out of the exhaust port 101. This prolongs the exhaust path and increases the resistance during the air flow process, making the air speed very slow before being discharged from the machine body, thereby reducing noise and improving the user experience. Furthermore, exhaust vents 101 are provided on both sides of the body, and the vacuum motor assembly is adapted to be placed between the exhaust vents 101 on both sides. Therefore, the exhaust path is extended and the air movement resistance is increased without increasing the volume, thereby reducing noise without increasing the volume.
[0096] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
