Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a microphone mounting structure and a household appliance. Background Technology

[0002] As voice interaction gradually becomes the most popular human-computer interaction method, voice interaction modules are needed in home appliances. These modules typically include a microphone, speaker, and control module.

[0003] In related technologies, microphone mounting structures include a pickup hole with the pickup hole facing the output hole. Since microphones are electrically charged components and are connected to the outside environment, dust and moisture easily accumulate on the inner circumference of the pickup hole after prolonged use, forming a conductive path. Therefore, the axial dimension of the pickup hole needs to be set relatively large to avoid the risk of electric creepage. However, when the axial dimension of the pickup hole is set too large, it can easily affect the microphone's sound pickup performance. Utility Model Content

[0004] In view of this, the present invention provides a microphone mounting structure and a household appliance to solve the problem in the related art that when the axial dimension of the sound receiving hole is set to be too large, it can easily affect the sound receiving effect of the microphone.

[0005] In a first aspect, this utility model provides a microphone mounting structure, including:

[0006] The housing has a mounting cavity and a microphone hole, and the mounting cavity is connected to the microphone hole.

[0007] A microphone is installed inside the mounting cavity, with the microphone's pickup hole facing the receiving hole. The inner circumference of the receiving hole is provided with a first annular protrusion, which is arranged along the circumference of the receiving hole and is located at the middle position of the receiving hole along the axial direction of the receiving hole.

[0008] Beneficial effects: The microphone mounting structure of this utility model embodiment has a first annular protrusion in the sound hole. The first annular protrusion is located in the middle of the sound hole. This means that when dust and moisture accumulate on the inner circumference of the sound hole and form a conductive path, the current needs to be transmitted outward along the surface of the first annular protrusion. This extends the creepage distance without increasing the axial dimension of the sound hole, thereby avoiding the risk of creepage and not affecting the microphone's sound reception effect.

[0009] Furthermore, since the microphone mounting structure of this utility model embodiment allows the axial dimension of the sound-receiving hole to be set to a large size while still meeting safety regulations, it can be applied to products with a relatively compact structure, thereby expanding the applicability of the microphone mounting structure and helping to improve the microphone's sound reception effect.

[0010] In one alternative embodiment, the minimum distance between the first annular protrusion and the microphone's sound-receiving hole is d1. min ;

[0011] 1.5mm≤d1 min ; and / or,

The minimum distance between the first side and the microphone's pickup hole is d2. min The minimum dimension of the first annular protrusion along the axial direction of the sound hole is d3. min ,d1 min ≤d2 min -d3 min .

[0013] Beneficial effects: When d1 min Within the aforementioned range, it can be ensured that the current extends along the wall of the first annular protrusion without directly penetrating it, thus ensuring that the first annular protrusion can reliably extend the creepage distance. The microphone hole meets safety requirements and has good structural strength, which helps to improve the aesthetics of the microphone mounting structure.

[0014] In one alternative implementation, 1.5mm ≤ d1 min ≤5.3mm; and / or,

[0020] The maximum diameter of the first aperture section is d4max, and the minimum diameter of the microphone is d8. min d4max≤d8min .

[0021] Beneficial effects: With this configuration, the minimum diameter of the first aperture segment is greater than or equal to the maximum diameter of the second aperture segment, thus forming a connecting segment extending radially along the microphone hole between the first and second aperture segments. The connecting segment can be used to extend the creepage distance of the microphone hole. The maximum diameter of the first aperture segment is less than or equal to the minimum diameter of the microphone, thus preventing the microphone from moving toward the first aperture segment and detaching from the mounting cavity.

[0022] In one alternative embodiment, the minimum diameter of the second hole segment is d5. min The maximum diameter of the microphone's pickup hole is d9. max ,d9 max ≤d5 min ; and / or,

[0023] The maximum diameter of the second aperture section is d5max, and the minimum diameter of the microphone is d8. min d5max≤d8 min .

[0024] Beneficial effects: By configuring the second aperture section in this way, the minimum diameter is greater than or equal to the diameter of the microphone's pickup hole, thus preventing the second aperture section from interfering with the microphone's sound pickup and ensuring good sound reception. The maximum diameter of the second aperture section is less than or equal to the minimum diameter of the microphone, preventing the microphone from moving towards the second aperture section and detaching from the mounting cavity.

[0025] In one alternative embodiment, the minimum diameter of the third hole segment is d6. min ;

[0026] The maximum diameter of the second section is d5. max d5 max ≤d6 min ; and / or,

[0027] d6 min ≤7mm.

[0028] Beneficial effect: With this configuration, the maximum diameter of the second hole segment is less than or equal to the minimum diameter of the third hole segment, which can form a connecting segment extending radially along the sound hole at the junction of the second and third hole segments. The connecting segment can increase the creepage distance without increasing the axial dimension of the sound hole.

[0029] d6 min ≤7mm, which can prevent users' fingers from sticking in through the third hole section, improving the safety of the microphone mounting structure.

[0030] In one alternative implementation, the microphone further includes:

[0031] Microphone body;

[0032] A vibration damping sleeve is fitted over the microphone body. The vibration damping sleeve has an clearance opening. The projection of the clearance opening along the axial direction of the sound pickup hole at least partially overlaps with the projection of the microphone's sound pickup hole along the axial direction of the sound pickup hole.

[0033] Beneficial effects: The vibration damping sleeve can isolate mechanical vibration and physical impact, preventing these interferences from being transmitted to the microphone diaphragm through the shell, thereby significantly reducing low-frequency noise and friction noise and improving recording clarity.

[0034] In one optional embodiment, the microphone aperture has a first side and a second side disposed opposite to each other, the microphone is disposed on the second side of the microphone aperture, and the minimum distance between the first side and the microphone aperture is d2. min The average diameter of the first hole section is d4. mean The average diameter of the second hole section is d5. mean The average diameter of the third hole section is d6. mean The diameter of the side of the clearance opening facing the sound hole is d7;

[0035] 0.5(d6 mean -2d5 mean +d4 mean )≥8-d2 min -0.5(d4 mean -d7).

[0036] Beneficial effects: When d2 min d4 mean d5 mean d6 mean When the dimensional relationship between d7 and d7 meets the above range, the creepage distance can be guaranteed to meet the safety requirements.

[0037] In one alternative embodiment, the housing is provided with a second annular protrusion, and the sound-receiving hole is located on the inner periphery of the second annular protrusion.

[0038] Beneficial effect: By setting it up in this way, the second annular protrusion can be used to increase the radial dimension of the microphone hole, thereby ensuring that the creepage distance meets safety requirements when the housing material is thin.

[0039] In one alternative embodiment, the microphone mounting structure further includes an air vent grille disposed on the housing, and an avoidance groove is provided at the position corresponding to the second annular protrusion.

[0040] Beneficial effects: The air vent grille, located at the air outlet of the microphone mounting structure, can be used to control the airflow direction, filter impurities, protect internal components, and optimize aerodynamic performance.

[0041] Based on this, the air vent grille is provided with a clearance groove at the position corresponding to the second annular protrusion to avoid the second annular protrusion, which can ensure that the appearance of the second annular protrusion does not protrude and helps to improve the overall aesthetics.

[0042] In one alternative embodiment, the maximum dimension of the clearance groove along the axial direction of the sound-receiving hole is d10. max The air outlet grille also includes a connecting part on the side away from the clearance groove, and the minimum distance between the top surface of the grille teeth and the clearance groove is d11. min ;

[0043] 1≤d 11 min :d 10 max ≤4.

[0044] Beneficial effect: When the ratio between the connecting part and the clearance groove is within the above range, it can ensure that the air outlet grille can fully avoid the second annular protrusion without damaging the structural strength of the air outlet grille.

[0045] In one alternative embodiment, the outer periphery of the second annular protrusion is provided with a clearance slope, which is inclined toward the central axis of the second annular protrusion in the direction away from the microphone.

[0046] Beneficial effect: By setting it up in this way, the distance between the second annular protrusion and the air outlet grille can be increased, thereby reducing the adhesive depth of the air outlet grille and thus avoiding affecting the structural strength of the air outlet grille.

[0070] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0071] Current home appliances still rely on touch operation and infrared remote control for human-computer interaction, which presents many inconveniences. Traditional touch operation requires consumers to walk next to the machine to operate it, increasing the amount of physical effort required.

[0072] While infrared remote control can solve the above problems, it requires a remote control, which users need to find before use and the batteries need to be replaced after a long period of disuse, resulting in a poor user experience.

[0073] The following is combined Figures 1 to 9 The following describes embodiments of the present invention.

[0074] According to an embodiment of the present invention, a microphone mounting structure is provided, including a housing 1 and a microphone 2.

[0075] The housing 1 has a mounting cavity 101 and a microphone hole 102, which are connected. The microphone 2 is located in the mounting cavity 101, and the microphone hole 201 of the microphone 2 faces the microphone hole 102. The inner circumference of the microphone hole 102 is provided with a first annular protrusion 1021, which is arranged along the circumference of the microphone hole 102 and is located at the middle position of the microphone hole 102 along the axial direction of the microphone hole 102.

[0076] The microphone mounting structure of this utility model embodiment has a first annular protrusion 1021 inside the sound receiving hole 102. The first annular protrusion 1021 is located in the middle of the sound receiving hole 102. This allows the current to be transmitted outward along the surface of the first annular protrusion 1021 when dust and moisture accumulate on the inner circumference of the sound receiving hole 102 to form a conductive path. This extends the creepage distance without increasing the axial dimension of the sound receiving hole 102, thereby avoiding the risk of creepage and not affecting the sound receiving effect of the microphone 2.

[0077] Furthermore, since the microphone mounting structure of this utility model embodiment allows the axial dimension of the sound-receiving hole to be set to a large size while still meeting safety regulations, it can be applied to products with a relatively compact structure, thereby expanding the applicability of the microphone mounting structure and helping to improve the microphone's sound reception effect.

[0078] In the description of the embodiments of this application, it should be noted that the first annular protrusion 1021 is located in the middle position of the sound receiving hole 102, which means that the first annular protrusion 1021 is located between the two ends of the sound receiving hole 102, and is not necessarily the center point of the line connecting the two ends of the sound receiving hole 102.

[0079] In one embodiment, the first and second sides of the first annular protrusion 1021 are both planes, and the first and second sides are two sides of the first annular protrusion that are arranged opposite to each other along the central axis of the sound hole 102.

[0080] As an alternative implementation, in an embodiment not shown in the accompanying drawings, the radial cross-section of the first annular protrusion 1021 may also be arc-shaped.

[0081] In one embodiment, such as Figure 7 and Figure 8 As shown, the minimum distance between the first annular protrusion 1021 and the microphone 2's sound receiving hole 102 is d1. min ; 1.5mm≤d1 min .

[0082] With this configuration, the current can be ensured to extend along the wall of the first annular protrusion 1021 without directly penetrating it, thus ensuring that the first annular protrusion 1021 can reliably extend the creepage distance.

[0083] In one embodiment, the maximum dimension of the first annular protrusion 1021 along the axial direction of the sound receiving hole 102 is d3. max When the first annular protrusion 1021 is provided on the outer surface of the microphone mounting structure, d3 max The preferred size is greater than or equal to 0.9 mm.

[0084] In the description of the embodiments of this application, it should be noted that the appearance surface refers to the outer surface of the product that can be observed under normal use.

[0085] In one embodiment, d3 max The thickness of the housing 1 is determined to avoid shrinkage of the first annular protrusion 1021, which would compromise the aesthetics of the microphone mounting structure.

[0086] For example, when the thickness of the housing 1 is 2.2 mm, d3 max ≤1mm.

[0087] When the thickness of shell 1 is 2mm, d3 max ≤0.9mm.

[0088] As a possible implementation, in an embodiment not shown in the drawings, when the first annular protrusion 1021 is not provided on the outer surface of the microphone mounting structure, d3 max The size is not affected by the thickness of the shell 1.

[0089] In one embodiment, d3 max It is 1.2mm.

[0090] In one embodiment, the microphone 102 has a first side and a second side arranged opposite to each other, the microphone 2 is disposed on the second side of the microphone 102, and the minimum distance between the first side and the microphone 2's pickup hole 201 is d2. min The minimum dimension of the first annular protrusion 1021 along the axial direction of the sound receiving hole 102 is d3. min ,d1 min ≤d2 min -d3 min .

[0091] In one embodiment, such as Figure 8 As shown, 1.5mm≤d1 min ≤5.3mm. 1.5mm≤d2 min ≤8mm; 0.7mm≤d3 min ≤5mm.

[0092] In one embodiment, d2 min It is 6.5mm, d3 min It is 1.2mm.

[0093] When d1 min Within the aforementioned range, it can be ensured that the current extends along the wall of the first annular protrusion without directly penetrating it, thus ensuring that the first annular protrusion can reliably extend the creepage distance. The microphone hole meets safety requirements and has good structural strength, which helps to improve the aesthetics of the microphone mounting structure.

[0094] In one embodiment, d1 min It is 2mm.

[0095] In one embodiment, the microphone hole 102 includes a first hole segment 1022, a second hole segment 1023 and a third hole segment 1024 arranged sequentially in a direction away from the microphone 2, and the second hole segment 1023 is formed on the inner periphery of the first annular protrusion 1021.

[0096] In one embodiment, such as Figure 9 As shown, the minimum diameter of the first hole segment 1022 is d4. min The maximum diameter of the second hole section 1023 is d5. max ,d5 max ≤d4 min .

[0097] With this configuration, the minimum diameter of the first aperture segment 1022 is greater than or equal to the maximum diameter of the second aperture segment 1023, thus forming a connecting segment extending in the radial direction of the sound receiving hole 102 between the first aperture segment 1022 and the second aperture segment 1023. The connecting segment can be used to extend the creepage distance.

[0098] In one embodiment, the radial cross-section of the first hole segment 1022 is circular, and d4 is the diameter of the radial cross-section of the first hole segment 1022.

[0099] As an alternative implementation, in an embodiment not shown in the drawings, the radial cross-section of the first hole segment 1022 may also be set as a triangle, a square or other polygon, in which case d4 is the diameter of the inscribed circle of the radial cross-section of the first hole segment 1022.

[0100] In one embodiment, the maximum diameter of the first hole segment 1022 is d4. max The minimum diameter of microphone 2 is d8. min d4max≤d8 min .

[0101] With this configuration, the maximum diameter of the first aperture segment 1022 is less than or equal to the minimum diameter of the microphone 2, which prevents the microphone 2 from moving toward the first aperture segment 1022 and from coming out of the mounting cavity 101.

[0102] In one embodiment, the minimum diameter d4 of the first hole segment 1022 min It is 5.28mm.

[0103] In one embodiment, the minimum diameter of the second hole segment 1023 is d5. min The maximum diameter of the microphone 2's pickup hole 201 is d9. max ,d9 max ≤d5min .

[0104] With this configuration, the minimum diameter of the second aperture 1023 is greater than or equal to the maximum diameter of the microphone's pickup hole 201, thereby preventing the second aperture 1023 from affecting the microphone 2's sound pickup and ensuring good sound pickup performance.

[0105] The pickup hole 201 can be a single pickup hole 201 or multiple small holes arranged in an array.

[0106] When the pickup hole 201 is a single pickup hole 201, and the single pickup hole 201 is a round hole, d9 max The diameter of the pickup hole 201.

[0107] When the pickup hole 201 is a single pickup hole 201, and the single pickup hole 201 is square, triangular, or other shapes, d9 max The diameter of the circumcircle of the pickup hole 201.

[0108] When the pickup hole 201 consists of multiple small holes arranged in an array, d9 max It is the diameter of the smallest circle that can enclose all the holes.

[0109] In one embodiment, d9 max =2.5mm.

[0110] In one embodiment, the radial cross-section of the second hole segment 1023 is circular, and d5 is the diameter of the radial cross-section of the second hole segment 1023.

[0111] As an alternative implementation, in an embodiment not shown in the drawings, the radial cross-section of the second hole segment 1023 may also be set as a triangle, a square or other polygon, in which case d5 is the diameter of the inscribed circle of the radial cross-section of the second hole segment 1023.

[0112] In one embodiment, the maximum diameter of the second hole segment 1023 is d5. max The minimum diameter of microphone 2 is d8. min d5max≤d8 min .

[0113] With this configuration, the maximum diameter of the second aperture segment 1023 is less than or equal to the minimum diameter of the microphone 2, which prevents the microphone 2 from moving toward the second aperture segment 1023 and from coming out of the mounting cavity 101.

[0114] In one embodiment, the maximum diameter d5 of the second hole segment 1023 max It is 2.7mm.

[0115] In one embodiment, the minimum diameter of the third hole segment 1024 is d6.min ;

[0116] The maximum diameter of the second hole section 1023 is d5max, and d5max ≤ d6. min .

[0117] With this configuration, the maximum diameter of the second hole segment 1023 is less than or equal to the minimum diameter of the third hole segment 1024, which allows a connecting segment extending radially along the sound hole 102 to be formed at the junction of the second hole segment 1023 and the third hole segment 1024. The connecting segment can increase the creepage distance without increasing the axial dimension of the sound hole 102.

[0118] In one embodiment, the minimum diameter d6 of the third hole segment 1024 min ≤7mm.

[0119] This design prevents users from inserting their fingers through the third hole 1024, thus improving the safety of the microphone mounting structure.

[0120] In one embodiment, d6 min It is 5mm.

[0121] In one embodiment, the radial cross-section of the third hole segment 1024 is circular, and d6 is the diameter of the radial cross-section of the third hole segment 1024.

[0122] As an alternative implementation, in an embodiment not shown in the drawings, the radial cross-section of the third hole segment 1024 may also be set as a triangle, a square or other polygon, in which case d6 is the diameter of the inscribed circle of the radial cross-section of the third hole segment 1024.

[0123] In one embodiment, such as Figure 9 As shown, the microphone includes a microphone body and a vibration damping sleeve 3.

[0124] The vibration damping sleeve 3 is fitted onto the microphone body. The vibration damping sleeve 3 has an avoidance opening 301. The projection of the avoidance opening 301 along the axial direction of the sound receiving hole 102 at least partially overlaps with the projection of the sound pickup hole 201 of the microphone 2 along the axial direction of the sound receiving hole 102.

[0125] The vibration damping sleeve 3 can isolate mechanical vibration and physical impact, preventing these interferences from being transmitted to the microphone diaphragm through the housing, thereby significantly reducing low-frequency noise and friction noise and improving recording clarity.

[0126] In one embodiment, the projection of the clearance 301 along the axial direction of the sound receiving hole 102 overlaps with the projection of the microphone 2 pickup hole 201 along the axial direction of the sound receiving hole 102, so as to ensure that the vibration damping sleeve 3 does not obstruct the microphone 2 pickup hole 201 in any way.

[0127] In one embodiment, the microphone 102 has a first side and a second side arranged opposite to each other along its axial direction, and the microphone 2 is disposed on the second side of the microphone 102. The minimum distance between the first side and the microphone 2's pickup hole 201 is d2. min The average diameter of the first hole section 1022 is d4. mean The average diameter of the second hole section 1023 is d5. mean The average diameter of the third hole section 1024 is d6. mean The diameter of the side of the clearance opening 301 facing the sound hole 102 is d7;

[0128] 0.5(d6 mean -2d5 mean +d4 mean )≥8-d2 min -0.5(d4 mean -d7).

[0129] When d2 min d4 mean d5 mean d6 mean When the dimensional relationship between d7 and d7 meets the above range, the creepage distance can be guaranteed to meet the safety requirements.

[0130] In one embodiment, 0.5(d4) mean -d7)=0.34mm.

[0131] In one embodiment, the housing 1 is provided with a second annular protrusion 103, and the sound receiving hole 102 is provided on the inner periphery of the second annular protrusion 103.

[0132] With this configuration, the second annular protrusion 103 can be used to increase the radial dimension of the microphone hole 102, thereby ensuring that the creepage distance meets safety requirements when the material thickness of the housing 1 is relatively thin.

[0133] In one embodiment, the microphone mounting structure further includes an air vent 4 disposed on the housing 1, and the air vent 4 is provided with a relief groove 401 at the position corresponding to the second annular protrusion 103.

[0134] The air vent 4 is located at the air outlet of the microphone mounting structure. It can be used to control the airflow direction, filter impurities, protect internal components, and optimize aerodynamic performance.

[0135] Based on this, the air outlet grille 4 is provided with a relief groove 401 at the position corresponding to the second annular protrusion 103. The relief groove 401 avoids the second annular protrusion 103, which can ensure that the appearance of the second annular protrusion 103 is not prominent, which helps to improve the overall aesthetics.

[0136] In one embodiment, the maximum dimension of the clearance groove 401 along the axial direction of the sound receiving hole 102 is d10. max The air outlet grille 4 also includes a connecting portion 402 on the side away from the clearance groove 401, and the minimum distance between the top surface of the grille teeth of the air outlet grille 4 and the clearance groove 401 is d 11. min ;

[0137] 1≤d 11 min :d 10 max ≤4.

[0138] When the ratio of the connecting part 402 to the clearance groove 401 is within the above range, it can be ensured that the air outlet grille 4 can fully avoid the second annular protrusion 103 without damaging the structural strength of the air outlet grille 4.

[0139] The top surface of the grille teeth refers to the surface of the grille teeth of the air outlet grille 4 that is furthest from the mounting base surface of the grille teeth, and the top surface of the grille teeth in this application is the original design surface of the top of the grille teeth that has not been chamfered or cut.

[0140] In a preferred embodiment, 1 ≤ d 11 min :d 10 max ≤3.

[0141] In one embodiment, the outer periphery of the second annular protrusion 103 is provided with a relief slope 1031, which is inclined toward the central axis of the second annular protrusion 103 in the direction away from the microphone 2.

[0142] By setting it in this way, the distance between the second annular protrusion 103 and the air outlet grille 4 can be increased, thereby reducing the adhesive reduction depth of the air outlet grille 4 and thus avoiding affecting the structural strength of the air outlet grille 4.

[0143] In one embodiment, such as Figure 9 As shown, the angle between the avoidance slope 1031 and the horizontal direction is θ, where 0°≤θ≤47.5°.

[0144] In one embodiment, θ is 45°.

[0145] According to an embodiment of the present invention, another aspect provides a household appliance, including: a microphone mounting structure, a speaker, and a control module.

[0146] The microphone mounting structure is the same as the microphone mounting structure provided in the first aspect of this utility model.

[0147] The microphone 2 is connected to the speaker and microphone mounting structure for communication.

[0148] In the use of the household appliance according to this utility model embodiment, the microphone 2 of the microphone mounting structure can be used to collect voice commands. The control module can generate corresponding interactive commands through the voice commands collected by the microphone 2 and control the speaker to play the interactive commands.

[0149] Therefore, the household appliances in this embodiment of the utility model have voice interaction function, so users can interact with them by voice without having to go to the vicinity of the household appliances, and can get adjustment feedback information from the household appliances, making operation convenient and providing a good user experience.

[0150] Based on this, the household appliance of the second aspect of the present invention includes or uses the microphone mounting structure of the first aspect of the present invention, and thus has its beneficial effects, namely: it can extend the creepage distance without increasing the axial dimension of the sound receiving hole 102, thereby avoiding the risk of creepage without affecting the sound receiving effect of the microphone 2.

[0151] Furthermore, since the microphone mounting structure of this utility model embodiment allows the axial dimension of the sound-receiving hole to be set to a large size while still meeting safety regulations, it can be applied to products with a relatively compact structure, thereby expanding the applicability of the microphone mounting structure and helping to improve the microphone's sound reception effect.

[0152] The control module may include programmable logic control components (such as PLC or CPU), memory, and electronic components connected to the programmable logic control components, which are well known to those skilled in the art and will not be described in detail here.

[0153] A communication connection refers to a communication link or session established between multiple devices, systems, or nodes for data transmission and exchange. It can be a physical connection or a logical connection. Physical connections are preferred, but not limited to, connections via hardware media such as cables, optical fibers, and wireless signals. Logical connections are preferred, but not limited to, links at the software layer such as TCP connections, virtual circuits (VPNs), and session layer protocols.

[0154] In the description of this application, it should be noted that "multiple" means two or more.

[0155] The home appliances of this utility model can be equipped with built-in voice models, such as Doubao, Siri, Xiao Ai, etc., so that users can complete various command operations simply by talking, which is convenient and quick.

[0156] 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 all such modifications and variations fall within the scope of protection claimed by the present invention.
