[0001] This application relates to the field of surface cleaning technology, and more particularly to a fan and surface cleaning equipment. Background Technology

[0002] As living standards continue to improve, floor cleaning equipment such as vacuum cleaners are increasingly appearing in people's daily lives.

[0003] When a vacuum cleaner is working, it mainly relies on the driving force of a fan to suck up dirt from the floor and achieve a cleaning effect. However, existing vacuum cleaners generate considerable noise from the fan during operation, affecting the user experience. Summary of the Invention

[0004] This application provides a fan and surface cleaning equipment to achieve noise reduction.

[0005] This application provides a fan, including a housing assembly and a core, wherein the core is installed in the housing assembly;

[0006] A guide plate protruding from one end plate of the housing assembly is provided facing the movement side. The guide plates are arranged around the periphery of the movement at intervals. A first gap is provided between the movement and the guide plate. The guide plate is spaced apart from the side plate group of the housing assembly and forms a second gap.

[0007] The air outlet of the mechanism is connected to the first gap, and the guide plate has a first notch on the side away from the air outlet that connects the first gap and the second gap;

[0008] The side plate assembly has an exhaust port that connects the second gap and the external environment of the housing assembly. The exhaust port is located on the side of the movement near the air outlet.

[0009] Based on the above technical solution, during the operation of the fan, the airflow discharged from the core can pass through the first gap and the second gap in sequence before being discharged through the exhaust port. The design of the first and second gaps extends the airflow output path, reduces the whistling sound of the airflow, and thus reduces the noise generated by the fan, achieving noise reduction and improving the user experience.

[0010] In some possible implementations, the housing assembly further includes a partition group spaced apart on the side of the guide plate away from the side plate group, the first gap being formed between the partition group and the guide plate, the partition group separating a receiving cavity in the housing assembly, the receiving cavity being located on the side of the partition group away from the first gap, and the movement being disposed in the receiving cavity;

[0011] The partition assembly has a second notch opposite to the air outlet, and the air outlet communicates with the first gap through the second notch.

[0012] In some possible implementations, the housing assembly includes a first housing and a second housing disposed opposite to each other;

[0013] The first housing includes an end plate and a side plate surrounding the periphery of the end plate. The guide plate protrudes from the end plate on the side near the movement and is spaced apart from the side plate. The second gap is formed between the guide plate and the side plate.

[0014] In some possible implementations, the fan further includes a first sound-absorbing cotton filling the first gap.

[0015] In some possible implementations, the fan further includes a second sound-absorbing cotton, which fills the second gap.

[0016] In some possible implementations, the end of the movement with the air inlet protrudes relative to one end of the housing assembly;

[0017] The fan also includes a first flexible component and a second flexible component. The first flexible component is sleeved on the end of the core near the air inlet and connected to the housing assembly. The second flexible component is placed between the end of the core away from the air inlet and the housing assembly.

[0018] In some possible implementations, the first flexible member has a first weight-reducing groove, and the second flexible member has a second weight-reducing groove.

[0019] In some possible implementations, the first flexible member has a positioning protrusion on its periphery, and the housing assembly has a positioning groove at one end near the first flexible member that mates with the positioning protrusion, with the positioning protrusion inserted into the positioning groove.

[0020] In some possible implementations, an end plate is provided at the end of the housing assembly away from the air inlet, and the second flexible member passes through the end plate and is exposed relative to the housing assembly;

[0021] The second flexible member has a circumferential protrusion with a limiting edge, which abuts against the side of the end plate near the mechanism.

[0045] like Figure 1 As shown, the embodiment provides a fan 1000, suitable for use in surface cleaning equipment. The fan 1000 provides suction in the surface cleaning equipment, drawing dirt and other contaminants from the surface to be cleaned into the dust collection structure of the surface cleaning equipment. The surface cleaning equipment can be one of the following: a vacuum cleaner, a sweeper, a floor scrubber, or a mop.

[0046] like Figure 1 and Figure 2 As shown, the fan 1000 may include a housing assembly 100 and a core 200.

[0047] Combined again Figure 3 The housing assembly 100 may be configured with an assembly cavity 101, and the movement 200 may be installed in the assembly cavity 101. In addition, a guide plate 113 protruding from one end of the housing assembly 100 and facing the assembly cavity 101 may be provided, that is, the guide plate 113 may be located on the side of the end plate 111 close to the assembly cavity 101.

[0048] In this embodiment, the guide plates 113 are arranged at intervals around the periphery of the movement 200, and a first gap 1012 is provided between the guide plates 113 and the movement 200. In addition, the guide plates 113 are also arranged at intervals with the sidewall of the housing assembly 100, forming a second gap 1013.

[0049] Combined again Figure 7 and Figure 8 It is understood that the mechanism 200 may include an air inlet 201 and an air outlet 202. In the embodiment, the air outlet 202 of the mechanism 200 may be connected to the first gap 1012. The guide plate 113 may have a first notch 1131 connecting the first gap 1012 and the second gap 1013 on the side away from the air outlet 202, that is, the first notch 1131 is located on the side of the mechanism 200 away from the air outlet 202. In addition, an exhaust port 102 is also provided on the side wall of the housing assembly 100. The exhaust port 102 may be located on the side wall of the housing assembly 100 away from the first notch 1131, that is, the position of the exhaust port 102 may be opposite to the position of the air outlet 202 of the mechanism 200.

[0050] During operation, airflow enters from the air inlet 201 of the movement 200 and exits from the air outlet 202. The airflow exiting from the air outlet 202 of the movement 200 enters the first gap 1012 and, under the guidance of the guide plate 113, moves to the side of the movement 200 away from the air outlet 202. It then passes through the first notch 1131 and enters the second gap 1013 from the first gap 1012. Subsequently, the airflow moves within the second gap 1013 towards the side of the movement 200 closer to the air outlet 202 and is output through the exhaust port 102 on the side wall of the housing assembly 100.

[0051] In this application, a guide vane 113 is installed inside the fan 1000, which can extend the output path of the airflow, reduce the whistling sound of the airflow, and thus reduce the noise generated by the fan 1000, thereby achieving noise reduction and improving the user experience.

[0052] like Figures 1 to 3 As shown, the housing assembly 100 may further include a first housing 110 and a second housing 120 that engage with each other. The first housing 110 and the second housing 120 may cooperate to form an assembly cavity 101. The first housing 110 may include an end plate 111 and a side plate 112 surrounding the end plate 111, and the end plate 111 may be located at one end of the side plate 112. In this embodiment, the first housing 110 may generally have a cylindrical structure.

[0053] In this embodiment, the second housing 120 may be generally cylindrical. One end of the second housing 120 may be fastened to the end of the side plate 112 of the first housing 110 away from the end plate 111. It is understood that the sidewall of the housing assembly 100 may include the side plate 112 of the first housing 110 and the second housing 120.

[0054] The side plate 112 is provided with a first fastening part 1121 at the end away from the end plate 111. The second housing 120 is provided with a second fastening part 121 that is adapted to the first fastening part 1121 at the end near the first housing 110, and the second fastening part 121 can be fastened and connected with the first fastening part 1121.

[0055] In some embodiments, the first fastening portion 1121 may be a latching block protruding from the side plate 112 away from the assembly cavity 101. The second fastening portion 121 may be a retaining ring protruding from the end of the second housing 120 near the first housing 110. When the first housing 110 is connected to the second housing 120, the second fastening portion 121 may be fastened to the first fastening portion 1121.

[0056] In other embodiments, the second fastening portion 121 may also be a latching block protruding from the side of the second housing 120 away from the assembly cavity 101. The first fastening portion 1121 may also be a retaining ring protruding from the side plate 112 near the end of the second housing 120.

[0057] Of course, in other embodiments, the second fastening part 121 may also be a hook that protrudes from the end of the second housing 120 near the first housing 110 and is adapted to the first fastening part 1121.

[0058] In the embodiments, the first fastening part 1121 and the second fastening part 121 can be configured as one pair, two pairs, three pairs, or five pairs as needed. When the first fastening part 1121 and the second fastening part 121 are configured as multiple pairs, the multiple pairs of the first fastening part 1121 and the second fastening part 121 can be evenly spaced around the periphery of the housing assembly 100 to ensure the stability of the connection between the first housing 110 and the second housing 120 at various points.

[0059] like Figure 3 and Figure 4 As shown, the side plate 112 also has an annular insertion groove 1122 at the end away from the end plate 111. The insertion groove 1122 can be U-shaped. The second housing 120 has an annular insertion plate 124 protruding from the end near the first housing 110. When the first housing 110 is connected to the second housing 120, the insertion plate 124 can be inserted into the insertion groove 1122, and the side wall of the insertion plate 124 can fit against the inner wall of the insertion groove 1122, which can improve the sealing effect at the connection position of the first housing 110 and the second housing 120.

[0060] like Figure 1 and Figure 3 As shown, the housing assembly 100 also includes a partition group 130, which can divide the assembly cavity 101 into a receiving cavity 1011 for accommodating the movement 200. Specifically, the partition group 130 may include a first partition 131 and a second partition 132.

[0061] The first partition 131 may protrude from the end plate 111 on the side near the assembly cavity 101 and extend towards the second housing 120. Furthermore, the first partition 131 may be tubular, and may be spaced apart from the side plate 112. The accommodating cavity 1011 may be located on the side of the first partition 131 away from the side plate 112. In this embodiment, the first partition 131 may be integrally formed with the first housing 110.

[0062] The second partition 132 may be disposed on the side of the second housing 120 near the assembly cavity 101. One end of the second partition 132 may be connected to the bend at the end of the second housing 120 away from the first housing 110, and the end of the second partition 132 near the first housing 110 may be spaced apart from the second housing 120. The second partition 132 may also be in the shape of a cylindrical tube and extend parallel to the direction near the first housing 110.

[0063] Combined again Figure 5 Additionally, an annular first assembly groove 1312 may be provided at the end of the first partition 131 away from the end plate 111. The first assembly groove 1312 may be located on the side of the first partition 131 away from the receiving cavity 1011, and the side of the first assembly groove 1312 away from the receiving cavity 1011 is an open structure.

[0064] The second partition 132 has an annular second assembly groove 1321 at one end near the first housing 110. The second assembly groove 1321 can be located on the side of the second partition 132 near the receiving cavity 1011, and the side of the second assembly groove 1321 near the receiving cavity 1011 is an open structure.

[0065] When the first housing 110 is connected to the second housing 120, the end of the first partition 131 away from the end plate 111 can be inserted into the second assembly groove 1321 and abut against the second partition 132. The end of the second partition 132 near the first housing 110 can be inserted into the first assembly groove 1312 and abut against the first partition 131. This achieves a seal at the connection point of the first partition 131 and the second partition 132, isolating the accommodating cavity 1011 from other spaces in the assembly cavity 101.

[0066] like Figure 1 and Figure 3As shown, the guide plate 113 may protrude from the end plate 111 on the side near the assembly cavity 101. The guide plate 113 may be located between the first partition plate 131 and the side plate 112, and the guide plate 113 is respectively spaced apart from the first partition plate 131 and the side plate 112. In the embodiment, the first gap 1012 may be formed between the first partition plate 131 and the guide plate 113, and the second gap 1013 may be formed between the guide plate 113 and the side plate 112.

[0067] Combined again Figure 7 and Figure 8 Additionally, a second notch 1311 may be provided on the first partition 131 to connect the accommodating cavity 1011 and the first gap 1012. The second notch 1311 may be opposite to the air outlet 202 of the mechanism 200, and the air outlet 202 of the mechanism 200 may be connected to the first gap 1012 through the second notch 1311. It can be understood that the second notch 1311 may be opposite to the side of the guide plate 113 away from the first notch 1131.

[0068] Combined again Figure 6 In some embodiments, the fan 1000 further includes a first sound-absorbing cotton 310 and a second sound-absorbing cotton 320. Both the first sound-absorbing cotton 310 and the second sound-absorbing cotton 320 can be in the form of a cylindrical tube. The first sound-absorbing cotton 310 can fill the first gap 1012, and its sidewalls can be respectively attached to the first partition 131 and the guide plate 113. The second sound-absorbing cotton 320 can fill the second gap 1013, and its sidewalls can be respectively attached to the guide plate 113 and the side plate 112. Additionally, the second sound-absorbing cotton 320 can extend to the second housing 120 and is located between the second housing 120 and the second partition 132.

[0069] It is understandable that the first sound-absorbing cotton 310 and the second sound-absorbing cotton 320 can provide the function of absorbing noise, further reducing the noise generated by the fan 1000 and achieving noise reduction. In the embodiment, the first sound-absorbing cotton 310 is disposed in the first gap 1012 and the second sound-absorbing cotton 320 is disposed in the second gap 1013, which can extend the path of airflow through the first sound-absorbing cotton 310 and the second sound-absorbing cotton 320 and improve the sound absorption and noise reduction effect.

[0070] like Figure 1 and Figure 2 As shown, the end of the core 200 near the air inlet 201 can protrude outward relative to the end of the second housing 120 away from the first housing 110, which facilitates the connection of the air inlet 201 of the core 200 to structures such as air ducts in surface cleaning equipment.

[0071] Furthermore, the wind turbine 1000 also includes a first flexible component 410 and a second flexible component 420.

[0072] The first flexible member 410 can be sleeved on the end of the movement 200 near the air inlet 201 and connected to the end of the second housing 120 away from the first housing 110. Additionally, the first flexible member 410 can be tightly fitted to the movement 200. It is understood that the air inlet 201 of the movement 200 can be exposed relative to the first flexible member 410.

[0073] In this embodiment, a mating protrusion 411 may be provided on the periphery of the first flexible member 410 near the end of the second housing 120, and the mating protrusion 411 may be located on the side of the first flexible member 410 near the second housing 120. A mating hole 122 that mates with the mating protrusion 411 may be provided on the periphery of the end of the second housing 120 away from the first housing 110. When the first flexible member 410 is connected to the second housing 120, the mating protrusion 411 can be inserted into the mating hole 122, thereby achieving a fixed connection between the first flexible member 410 and the second housing 120.

[0074] In the embodiments, the mating protrusions 411 and mating holes 122 are provided in pairs, two pairs, three pairs, or five pairs as needed. When there are multiple pairs of mating protrusions 411 and mating holes 122, the multiple pairs of mating protrusions 411 and mating holes 122 can be evenly spaced along the periphery of the second housing 120.

[0075] like Figure 1 As shown, further, a positioning protrusion 412 protrudes from the periphery of the first flexible member 410. A positioning groove 123, which mates with the positioning protrusion 412, is provided at the end of the second housing 120 away from the first housing 110. The positioning protrusion 412 can be inserted into the positioning groove 123. In this embodiment, the positioning and assembly of the first flexible member 410 and the second housing 120 can be achieved through the cooperation of the positioning protrusion 412 and the positioning groove 123.

[0076] In some embodiments, three pairs of positioning protrusions 412 and positioning grooves 123 may be provided, wherein the size of one pair of positioning protrusions 412 and positioning grooves 123 may be different from the size of the other two pairs of positioning protrusions 412 and positioning grooves 123.

[0077] In other embodiments, the positioning protrusions 412 and the positioning grooves 123 may also be provided as one pair, two pairs, or four pairs. When there are multiple pairs of positioning protrusions 412 and positioning grooves 123, the multiple pairs of positioning protrusions 412 and positioning grooves 123 may be arranged in a non-rotationally symmetrical manner.

[0078] Furthermore, a first weight-reducing groove 413 is provided on the side of the first flexible member 410 away from the mechanism 200. Multiple first weight-reducing grooves 413 may be provided. On the one hand, this reduces the weight of the first flexible member 410, thereby reducing the weight of the surface cleaning equipment. On the other hand, it also saves materials and reduces costs. Simultaneously, it facilitates pulling or squeezing the first flexible member 410 to cause corresponding elastic deformation, so that it can be assembled onto the mechanism 200 and the second housing 120.

[0079] In other embodiments, the first weight-reducing groove 413 may also be formed on the side of the first flexible member 410 near the movement 200. Alternatively, the first weight-reducing groove 413 may be formed simultaneously on both the side of the first flexible member 410 near the movement 200 and the side away from the movement 200.

[0080] In addition, the first flexible member 410 can seal the mounting position between the movement 200 and the second housing 120, and also achieve the effects of shock absorption and anti-resonance, reducing the vibration transmitted outward by the movement 200. In some embodiments, the first flexible member 410 can be made of silicone to achieve high temperature resistance.

[0081] In other embodiments, the first flexible member 410 may be made of materials such as rubber.

[0082] like Figure 2 , Figure 3 , Figure 7 and Figure 9 As shown, the second flexible member 420 can be disposed between the movement 200 and the end plate 111 to achieve shock absorption and anti-resonance effects. Specifically, the end plate 111 can have a through hole 1111 opposite to the movement 200. The second flexible member 420 can pass through the through hole 1111. In addition, a limiting edge 421 protrudes from the peripheral side of the second flexible member 420 near the end of the movement 200, and the limiting edge 421 can abut against the side of the end plate 111 near the receiving cavity 1011. In the embodiment, the second flexible member 420 can abut against both the movement 200 and the end plate 111. In addition, the peripheral side of the second flexible member 420 can also be tightly fitted with the inner wall of the through hole 1111 to achieve fixed installation of the second flexible member 420, and at the same time, to achieve sealing at the connection position between the second flexible member 420 and the end plate 111. In some embodiments, the second flexible member 420 can be made of silicone.

[0083] In other embodiments, the second flexible member 420 may be made of a flexible material such as rubber.

[0084] In this embodiment, the second flexible member 420 has second weight-reducing grooves 423 on both the side near the core 200 and the side away from the core 200. This reduces the weight of the second flexible member 420, thereby reducing the weight of the surface cleaning equipment. It also saves materials and reduces costs. Furthermore, it allows for easy pulling or squeezing of the second flexible member 420 to induce corresponding elastic deformation, facilitating its assembly onto the first housing 110.

[0085] In other embodiments, the second weight-reducing groove 423 may be formed only on the side of the second flexible member 420 close to the movement 200 or on the side away from the movement 200.

[0086] Combined again Figure 10 In addition, the fan 1000 also includes a seal 430, which is disposed around the periphery of the end of the second flexible member 420 that protrudes relative to the end plate 111, and is located on the side of the second flexible member 420 away from the core 200. The seal 430 can cover the connection between the second flexible member 420 and the end plate 111.

[0087] In this embodiment, two connecting posts 422 protrude from the side of the second flexible member 420 away from the movement 200. A connecting groove 431 is formed on the side of the sealing member 430 near the second flexible member 420, which mates with the connecting posts 422. The connecting posts 422 can be inserted into the connecting groove 431, and the connecting posts 422 can be tightly fitted with the connecting groove 431. In some embodiments, the sealing member 430 may also be made of silicone, which can further provide shock absorption.

[0088] In other embodiments, the seal 430 may be made of a flexible material such as rubber.
