Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, in particular to the field of self-cleaning of washing machines and clothes dryers, and in particular to a non-obstruction noise-reducing cleaning brush head, a cleaning brush and a cleaning device. Background Art

[0002] The present technology is based on the defects of the built-in cleaning brush structure of a washing machine (drum washing machine and pulsator washing machine) with a cleaning brush device during application: since the cleaning brush bodies arranged in the inner and outer drums are always in opposite directions during the washing and dehydration processes, there is mutual force during the washing and dehydration work. The high-frequency mutual force factors make the cleaning brush body easy to deform, which not only reduces the cleaning intensity, but also, the key is that in the dehydration state, due to the high-speed rotation of the inner drum, the friction between the cleaning brush bodies increases several times, which will inevitably produce higher decibel noise, and the service life of the brush body is greatly reduced.

[0003] 1. The existing design of the cleaning brush structure improves the cleaning ability of the washing machine, but also has disadvantages. Details are as follows:

[0004] 1. Easy to wear out. The conventional cleaning brush bodies designed and arranged with inner and outer cylinders will be squeezed and bent when they pass each other, which reduces the service life of the cleaning brushes.

[0005] 2. Reduced strength. Long-term washing and high-speed dehydration lead to frequent bending, which results in a real-time weakening of the cleaning ability of the cleaning brush. As a result, the cleaning strength is easily weakened, and the cleanliness of the drum is reduced.

[0006] 3. The noise is high. Since the layout surface of the cleaning brush body includes the circumference of the inner and outer cylinders, the bottom end surface, and the front end surface, at least one group (6) of cleaning brushes must be arranged, and in order to improve the cleanliness and reduce the workload caused by the user's replacement of cleaning brushes, multiple groups (12 or 36) of cleaning brushes may need to be arranged. Therefore, the cleaning brush body will produce higher noise in the washing and dehydration states, especially in the dehydration state when the washing machine is running at the highest level. The high decibel noise not only affects the user experience, but also poses a major disadvantage when used at night and in maintenance environments. Utility Model Content

[0007] In order to solve the above problems, the utility model provides a non-obstruction noise reduction cleaning brush head, a cleaning brush and a cleaning device which have a simple structure, can significantly reduce noise, ensure cleaning ability and extend service life.

[0008] The utility model discloses a non-obstruction noise-reducing cleaning brush head, comprising a brush body formed by clustered bristles, wherein one end of the brush body used for cleaning is a cleaning end, and the other end corresponding to the cleaning end is a connecting end.

[0014] A non-obstruction noise reduction cleaning brush comprises a base connected to an external device, and a plurality of non-obstruction noise reduction cleaning brush heads are arranged in a row on the base.

[0015] Preferably, in the same row of non-obstruction noise-reducing cleaning brush heads, the cleaning ends of two adjacent non-obstruction noise-reducing cleaning brush heads are in contact with each other.

[0016] Preferably, the base is embedded in the external device.

[0017] Preferably, a side of the base close to an unobstructed noise reduction cleaning brush head is flush with a side of the external device where the base is located.

[0018] A non-obstruction noise reduction cleaning device, comprising non-obstruction noise reduction cleaning brushes respectively arranged on two corresponding surfaces, the non-obstruction noise reduction cleaning brush on one surface is a first cleaning brush, the non-obstruction noise reduction cleaning brush on the corresponding surface is a second cleaning brush, and the non-obstruction noise reduction cleaning brush head on the first cleaning brush and the non-obstruction noise reduction cleaning brush head on the second cleaning brush are both staggered;

[0019] When the first cleaning brush passes the second cleaning brush, an unobstructed noise reduction cleaning brush head on the second cleaning brush passes through the area between two adjacent unobstructed noise reduction cleaning brush heads on the first cleaning brush and cleans the connecting end of an unobstructed noise reduction cleaning brush head on the first cleaning brush.

[0020] Preferably, a non-obstructive noise-reducing cleaning brush is detachably connected to the surface.

[0021] The utility model has a simple structure, can greatly reduce noise, ensure cleaning ability and prolong service life.

[0022] The utility model utilizes the flared design of the cleaning end to ensure the cleaning ability and solves the problem of reducing the contact area with the cleaning brush moving in the opposite direction, avoiding obstruction, resistance and bending deformation.

[0023] The connection end of the utility model has a streamlined structure in the cleaning direction that can reduce fluid resistance, thereby reducing the water resistance coefficient during washing and the wind resistance coefficient during high-speed dehydration, thereby greatly reducing the bending deformation of the brush body and significantly reducing noise decibels.

[0024] The utility model discloses a non-obstruction noise reduction cleaning device. When the first cleaning brush passes through the second cleaning brush, the non-obstruction noise reduction cleaning brush head on the second cleaning brush passes through the area between two adjacent non-obstruction noise reduction cleaning brush heads on the first cleaning brush. Since the two adjacent cleaning ends are in contact, the connection end can be cleaned, thereby achieving cleaning without dead angles. The streamlined structure achieves higher passability of the two cleaning brushes and reduces the degree of shrinkage deformation of the brush body when it touches and the impact force when the connection ends are alleviated, thereby reducing the friction intensity, reducing the force conflict, improving the passability of the brush body when it is misaligned, and ensuring that the end of the cleaning brush is more durable, and the noise generated by the decibel is lower and quieter.

[0025] The base of the utility model is embedded on the external equipment, so that the cleaning brush can operate without hindrance during the operation, and good cleaning passability is guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The utility model discloses a non-obstructed noise-reducing cleaning brush head, comprising a brush body formed by clustered bristles, wherein one end of the brush body used for cleaning is a cleaning end 1, and the other corresponding end is a connecting end 2, and in the cleaning direction: the cleaning end 1 is in a flared shape, that is, in the direction from the cleaning end 1 to the connecting end 2, the cleaning end 1 changes from wide to narrow, such as a fan shape, an inverted triangle, or an inverted trapezoid.

[0037] The connection end 2 is a streamlined structure in the cleaning direction that can reduce fluid resistance.

[0038] The streamlined structure includes a left side portion and a right side portion arranged along the cleaning direction and a middle portion arranged between the left side portion and the right side portion;

[0039] The width of the left side away from the middle part is smaller than the width of the left side near the middle part, and the width of the right side away from the middle part is smaller than the width of the right side near the middle part.

[0040] The left side portion and the right side portion are connected to the middle portion with a smooth transition.

[0041] A non-obstruction noise reduction cleaning brush comprises a base 3 connected to an external device, and a plurality of non-obstruction noise reduction cleaning brush heads are arranged in a row on the base 3.

[0042] On the same row of non-obstruction noise reduction cleaning brush heads, the cleaning ends 1 of two adjacent non-obstruction noise reduction cleaning brush heads are in contact with each other.

[0043] The base 3 is embedded in the external device.

[0044] A side of the base 3 close to the unobstructed noise reduction cleaning brush head is flush with a side of the external device where the base 3 is located.

[0045] A non-obstruction noise reduction cleaning device, comprising non-obstruction noise reduction cleaning brushes respectively arranged on two corresponding surfaces, the non-obstruction noise reduction cleaning brush on one surface is a first cleaning brush, the non-obstruction noise reduction cleaning brush on the corresponding surface is a second cleaning brush, and the non-obstruction noise reduction cleaning brush head on the first cleaning brush and the non-obstruction noise reduction cleaning brush head on the second cleaning brush are both staggered;

[0046] When the first cleaning brush passes the second cleaning brush, the unobstructed noise reduction cleaning brush head on the second cleaning brush passes through the area between two adjacent unobstructed noise reduction cleaning brush heads on the first cleaning brush and cleans the connecting end 2 of the unobstructed noise reduction cleaning brush head on the first cleaning brush.

[0047] A non-obstruction noise-reducing cleaning brush is detachably connected to the surface on which it is located.

[0048] When in use, the cleaning end 1 is formed into a fan shape by gluing or thermoplasticizing, or is tied into a fan shape with a metal belt in the prior art, and the connecting end 2 is a streamlined structure that can reduce fluid resistance in the cleaning direction. The connecting end 2 is also streamlined by gluing or thermoplasticizing, or is tied into a streamlined shape with a metal belt in the prior art.

[0049] The non-obstruction noise reduction cleaning device formed by a non-obstruction noise reduction cleaning brush arranged on the circumference of the inner drum of the washing machine and a non-obstruction noise reduction cleaning brush arranged on the circumference of the outer drum of the washing machine is explained as an example: during the washing or dehydration process, the inner drum rotates, the non-obstruction noise reduction cleaning brush on the inner drum cleans the inner circumference of the outer drum, and the non-obstruction noise reduction cleaning brush arranged on the inner circumference of the outer drum cleans the outer circumference of the inner drum. When the non-obstruction noise reduction cleaning brush on the inner drum passes through the non-obstruction noise reduction cleaning brush on the outer drum, the non-obstruction noise reduction cleaning brush head on the non-obstruction noise reduction cleaning brush on the inner drum passes through the area between two adjacent non-obstruction noise reduction cleaning brush heads on the non-obstruction noise reduction cleaning brush on the outer drum, and the two non-obstruction noise reduction cleaning brush heads on the outer drum are squeezed during the passing process. Under the mutual force, the two non-obstruction noise reduction cleaning brush heads and The fan-shaped cleaning ends 1 on the non-obstruction noise-reducing cleaning brush heads on the inner cylinder will retract to facilitate the passage of the non-obstruction noise-reducing cleaning brush heads on the inner cylinder, and at the same time, the connecting ends 2 of the non-obstruction noise-reducing cleaning brush heads on the inner cylinder and the outer cylinder can be cleaned, thereby achieving cleaning without dead angles. At the same time, since the connecting end 2 of the non-obstruction noise-reducing cleaning brush heads is streamlined in design, the smooth passage is achieved and the noise decibel is greatly reduced. Since the non-obstruction noise-reducing cleaning brush heads on the first cleaning brush and the non-obstruction noise-reducing cleaning brush heads on the second cleaning brush are staggered, no frontal contact will occur, the deformation amount is reduced, and the service life is greatly extended. At the same time, in the dehydration working state, the inner cylinder rotates at a high speed. The utility model greatly reduces the contact area and contact resistance of the non-obstruction noise-reducing cleaning brushes on the inner cylinder and the outer cylinder, reduces the bending deformation amount and the number of deformations, and reduces the loss.

[0050] The utility model has a simple structure, can greatly reduce noise, ensure cleaning ability and prolong service life.

[0051] The utility model utilizes the flared design of the cleaning end 1 to ensure the cleaning ability and solves the problem of reducing the contact area with the cleaning brush moving in the opposite direction, avoiding obstruction, resistance and bending deformation.

[0052] The connection end 2 of the utility model is a streamlined structure capable of reducing fluid resistance in the cleaning direction, thereby reducing the water resistance coefficient during washing and the wind resistance coefficient during high-speed dehydration, thereby greatly reducing the bending deformation of the brush body and significantly reducing the noise decibel.

[0053] The utility model discloses a non-obstruction noise reduction cleaning device. When the first cleaning brush passes through the second cleaning brush, the non-obstruction noise reduction cleaning brush head on the second cleaning brush passes through the area between two adjacent non-obstruction noise reduction cleaning brush heads on the first cleaning brush. Since the two adjacent cleaning ends 1 are in contact, the connection end 2 can be cleaned, thereby achieving cleaning without dead angles. The streamlined structure achieves higher passability of the two cleaning brushes and reduces the degree of shrinkage deformation of the brush body when it touches and the impact force when the connection end 2 is relaxed, thereby reducing the friction intensity, reducing the force conflict, improving the passability of the brush body when it is misaligned, and ensuring that the end of the cleaning brush is more durable, and the noise generated by the decibel is lower and quieter.

[0054] The base 3 of the utility model is embedded in the external equipment, so that the cleaning brush can work without hindrance in the operation process, and good cleaning passability is guaranteed.
