Description

Technical Field

[0001] The utility model relates to the technical field of musical instruments, in particular to a new-style tuned diatonic harmonica with an in-built overblow control assistor. Background Art

[0002] The harmonica is one of the most popular musical instruments in China and even the world. The existing harmonicas are mainly divided into three types, namely the tremolo harmonica (accent harmonica), the chromatic harmonica, and the 10-hole diatonic harmonica (also called the 10-hole blues harmonica).

[0003] The current 10-hole diatonic harmonica (10-hole blues harmonica) still follows the classic European design of the 19th century. The tuning arrangement of the reeds is the Richter tuning. This harmonica has two harmonica covers, a 10-hole fretboard, and two metal reed plates. Each reed plate has 10 reed tongues. Each sound hole has two reed tongues for blowing and sucking. One end of each reed tongue is welded or riveted to the reed tongue plate. The outer dimension of the reed tongue is just smaller than the reed tongue groove, and it can vibrate freely in the reed tongue groove. The reed tongues are the blowing reed tongue and the sucking reed tongue respectively, and two sounds with different pitches are emitted through the vibration of the blowing and sucking reed tongues. The covers, fretboard, and reed plates are fastened together by screws or riveting.

[0004] The following is a comparison table of the normal blowing and sucking notes, bending, overblowing, and over-sucking notes of the 10-hole Richter tuning blues diatonic harmonica.

[0005] Overblow #2 #5 #2 #4 #6 Blowing pressure bending 3b 5b 7、7b Blowing sound 1 3 5 1 3 5 1 3 5 1 Hole position 1 2 3 4 5 6 7 8 9 10 Sound absorption 2 5 7 2 4 6 7 2 4 6 Suction pressure bending 2b 5b、4 7b, 6, 6b 2b 6b Over suction #1 #5 #1

[0006] To facilitate the performance of minor music, pop music, and Irish music, and also take into account the performance of blues music, the blowing note of the 3rd hole of the 10-hole blues harmonica is changed to 6, which becomes a 10-hole Paddy tuning blues diatonic harmonica.

[0007] The advantages of the 10-hole Richter tuning blues diatonic harmonica are:

[0008] 1. It has strong timbre expressiveness, a relatively large volume, diverse playing techniques. The glissando using the bending technique is its characteristic, and there are various tremolo, vibrato, and glissando performance techniques.

[0009] 2. It is very suitable for playing blues music in the second position, and is also very suitable for playing folk and rock music.

[0010] 3. It is small in size, simple in structure, durable, and easy to carry.

[0011] 4. In the mid-low pitch range, the multi-hole blowing note is the major chord, and the multi-hole sucking note is the minor chord.

[0012] The disadvantages of the 10-hole Richter tuning diatonic harmonica are:

[0013] 1. The notes 4 and 6 in the low pitch range need to be achieved through bending techniques. For harmonica learners, it is quite difficult to learn the full tone bending of the third hole. When bending a full tone to get the note 6, the pitch is unstable and the timbre is rather abrupt, making it unsuitable for playing minor music with 6 as the tonic note.

[0014] 2. In actual musical performances, special playing techniques are often required to obtain additional notes to achieve the expected effects. Besides the bent notes obtained through bending techniques, many half - tones need to be achieved through overblowing and overdrawing techniques.

[0015] (1) Inhale bending: On the first to the sixth holes, when inhaling, by changing the shape of the oral cavity and the tongue to change the angle of the airflow, through the interaction of the inhaling reed and the blowing reed in this sound hole, the pitch of the inhaling sound is lowered (the note with the lowered pitch is between the inhaling sound and the blowing sound within this sound hole).

[0016] (2) Exhale bending: On the seventh to the tenth holes, when exhaling, by changing the shape of the oral cavity and the tongue to change the angle of the airflow, through the interaction of the inhaling reed and the blowing reed in this sound hole, the pitch of the exhaling sound is lowered (the note with the lowered pitch is between the exhaling sound and the inhaling sound within this sound hole).

[0017] (3) Overblowing: On the first to the sixth holes, when exhaling, by changing the shape of the mouth, the tongue, and the throat, the airflow blown out of the oral cavity closes the blowing reed (the reed vibrates slightly with a very small amplitude in the reed slot), forcing the airflow to point to the inhaling reed, and thus making the inhaling reed sound, obtaining a note with a pitch half - tone higher than the inhaling note.

[0018] (4) Overdrawing: On the seventh to the tenth holes, when inhaling, by changing the shape of the mouth, the tongue, and the throat and appropriately controlling the intensity and direction of the airflow, the inhaling reed is closed, forcing the airflow to point to the blowing reed, making the blowing reed vibrate and obtaining a note with a pitch half - tone higher than the normal blowing note of this reed.

[0019] 3. The techniques of overblowing and overdrawing are very difficult to master, often accompanied by whistling phenomena, and it is also not easy to control the timbre and intonation.

[0020] 4. Because overblowing and overdrawing require long - term training and certain talent to be mastered, the vast majority of learners and performers cannot master these techniques.

[0021] 5. The scale arrangements in the low pitch range, middle pitch range, and high pitch range are all different, which is not convenient for learning.

[0022] In the prior art, for example, a diatonic harmonica and its auxiliary controllable housing disclosed in the patent application No. CN201811178918.X. It is very difficult to find the corresponding air holes that need to be blocked during playing with this patented technology. Blocking the holes with fingers is very uncomfortable and inconvenient, and it is very difficult to ensure airtightness.

[0023] For another example, a blues 10-hole diatonic harmonica with a super blow control auxiliary device designed and manufactured by the Japanese Suzuki Harmonica Company. It is very difficult to ensure airtightness during operation, with serious air leakage, and it is very difficult to control overtones, resulting in product failure.

[0024] For another example, the US patent Harmonica and method of playing same with the patent number 5739446. It is very difficult to meet the requirements in terms of airtightness, resulting in poor playing effects.

[0025] For another example, a harmonica overblow enhancement component and an overblow harmonica disclosed in the patent application No. CN201820598804.X. The overblow air guide holes of this design are two upper and lower rows of holes at the rear of the harmonica. When blocking the air guide holes with the straight right hand fingers, it is necessary to determine which note it is, and decide whether to block the upper or lower air guide holes. Moreover, the action of blocking the air guide holes needs to be frequently changed between the upper and lower rows of air guide holes, and it is not easy to master and control the position of the fingers, which easily leads to mistakes in playing overblow notes. To overcome this shortcoming, a gas blocking baffle link is designed in this creation. When using the gas blocking link for operation, since the opening and closing rotation of the link and the connecting end of the harmonica are connected by two screw shafts, it is not easy to ensure that the angle of the baffle blocking the outer edge of the air guide hole is straight, resulting in easy air leakage and poor airtightness, which easily leads to failure in playing overblow notes. In addition, there is no fixed position limit for the additional baffle link. The long, dangling baffle link is very easy to damage and needs to be carefully stored, making the harmonica lose the advantage of portability.

[0026] Therefore, a new type of diatonic harmonica with an internal overblow control auxiliary device and a new tuning arrangement is proposed to solve the existing deficiencies. Summary of the Utility Model

[0027] The technical problem to be solved by the present utility model is to overcome the defects of the above-mentioned technologies and provide a new type of diatonic harmonica with an internal overblow control auxiliary device and a new tuning arrangement.

[0028] To solve the above technical problem, the technical solution provided by the present utility model is a new type of diatonic harmonica with an internal overblow control auxiliary device and a new tuning arrangement, comprising a harmonica body;

[0029] The harmonica body includes a blowing sound cover plate, an overblow isolation airway module, a blowing sound reed plate, a fret, a sound-absorbing reed plate, and a sound-absorbing cover plate. A number of linearly increasing sound holes are evenly arranged along the length direction on the fret. A blowing sound reed plate and a sound-absorbing reed plate are respectively arranged on the upper and lower sides of the fret. Sound reed grooves corresponding to the sound holes are provided on the blowing sound reed plate and the sound-absorbing reed plate. An overblow isolation airway module is provided on the blowing sound reed plate. A partition cavity arranged linearly and corresponding to the sound reed groove is provided in the overblow isolation airway module. The partition cavity in the overblow isolation airway module and the blowing sound reed plate form an overblow isolation airway; a blowing sound cover plate is arranged outside the blowing sound reed plate and the overblow isolation airway module; a sound-absorbing cover plate is arranged outside the sound-absorbing reed plate;

[0030] It further includes a blowing sound reed piece and a sound-absorbing reed piece. The blowing sound reed piece is arranged on the blowing sound reed plate and is adapted to the sound reed groove. The sound-absorbing reed piece is arranged on the sound-absorbing reed plate and is adapted to the sound reed groove.

[0031] As an improvement, the pitch of the corresponding sound hole is controlled by the thickness and length of the blowing sound reed piece and the sound-absorbing reed piece.

[0032] As an improvement, the overblow isolation airway module includes an isolation airway upper plate, an isolation airway outer plate, an isolation airway bottom plate, and an isolation airway baffle. The overblow isolation airway module is fixedly arranged on the upper side of the blowing sound reed plate.

[0033] As an improvement, the overblow isolation airway module is closely attached to the blowing sound reed plate.

[0034] As an improvement, the outlet of the partition cavity in the overblow isolation airway module is flush with the rear end of the fret.

[0035] The advantages of the present utility model compared with the prior art are as follows:

[0036] 1. All whole tones and semitones within 2.5 octaves can be played simply and conveniently. At the same time, without the need for bending, the natural blowing and sucking of the reeds can obtain the bass 4 and bass 6.

[0037] 2. No special playing techniques such as bending and overblowing are required. The natural blowing and sucking of the reeds on the harmonica obtain the natural scales of two keys, C major and F major (1, 2, 3, 4, 5, 6, 7, taking a C harmonica as an example), which is simple and easy to use;

[0038] The bending technique in the high pitch range eliminates the blowing bending technique and combines the use of the sucking bending technique. At the same time, the three-octave scales in the bass, middle, and high pitch ranges are arranged in the same way, which is convenient for learning, memorizing, and mastering;

[0039] 3. By using the overblow isolation airway module, techniques such as tongue trill, jaw trill, throat trill, hand trill, and upward glide can be applied to overblown notes, with strong control and rich expressiveness. Moreover, overblown notes are easy to quickly learn and master, and the pitch and timbre of overtones can be precisely controlled;

[0040] 4. For overblowing, place the side of the middle finger or index finger of the right hand flat against the air outlet of the overblow control auxiliary isolation airway to block the air outlet of the overblow isolation airway module, and blow the inhalation reed in the sound hole to produce overblown notes. Overblown notes are easier to obtain, with a pure timbre and simple and practical operation.

[0041] 5. With the overblown notes using the overblow isolation airway module, through the control and coordination of fingers and the oral cavity, the pitch and timbre of overtones can be precisely and quickly controlled. Ornamental techniques such as lip trill, throat trill, hand trill, upward glide, and downward glide can be played on overblown notes, expanding the musical expressiveness of the harmonica;

[0042] 6. The upward glide of overblowing can raise the pitch by another semitone through the shape of the mouth cavity and airflow control. In this way, the upward glide of each blowing note can be obtained through the overtone of the adjacent sound hole on the left. Since each drawing note can achieve a draw bend upward glide through the draw bend technique, and after the implementation of this solution, the overtone upward glide of each blowing note can be achieved, thus greatly expanding the musical expressiveness of the harmonica.

[0043] 7. By using the side of the middle finger or index finger placed flat to block the air outlet of the overblow isolation airway, it is convenient to play pure overblown notes, and each reed is redesigned for tuning, eliminating blowing draw bend and overdraw. Thus, all the missing semitone notes on the diatonic harmonica are complemented through draw bend and overblowing, making the diatonic harmonica an instrument that is easy to learn, powerful in function, rich in timbre, small in size, durable, and convenient to operate, capable of playing pop music, classical music, jazz, blues music, and music of various ethnic groups around the world.

[0044] 8. It has a relatively large volume, strong timbre control, powerful timbre expressiveness, simple structure, no moving parts, is not easily damaged, is convenient to learn, has powerful playing functions, can play major and minor key music in all keys, and can also play various styles of music including pop music, classical music, jazz, folk music, blues, rock, and music of various ethnic groups around the world.

[0058] Embodiment 1

[0059] A chromatic harmonica with a new tuning arrangement with an in-built overblow control assistor, comprising a harmonica body;

[0060] The harmonica body includes a blowing sound cover plate 1, an overblow isolation airway module 2, a blowing sound reed plate 3, a harmonica grille 4, a sound-absorbing reed plate 5, and a sound-absorbing cover plate 6. Along the length direction of the harmonica grille 4, a number of linearly increasing sound holes 7 are evenly provided. Specifically, the number of the sound holes 7 can be set according to actual needs. In this embodiment, the number of the sound holes 7 is 10.

[0061] A blowing sound reed plate 3 and a sound-absorbing reed plate 5 are respectively arranged on the upper and lower sides of the harmonica grille 4. Sound reed slots 8 corresponding to the sound holes 7 are provided on the blowing sound reed plate 3 and the sound-absorbing reed plate 5. An overblow isolation airway module 2 is provided on the blowing sound reed plate 3. Linear-arranged partition cavities 9 corresponding to the sound reed slots 8 are provided in the overblow isolation airway module 2. The partition cavities 9 in the overblow isolation airway module 2 and the blowing sound reed plate 3 form an overblow isolation airway;

[0062] Specifically, the overblow isolation airway module 2 includes an isolation airway upper plate 12, an isolation airway outer side plate 13, an isolation airway bottom plate 14, and an isolation airway baffle 15. The overblow isolation airway module 2 is fixedly arranged on the upper side of the blowing sound reed plate 3.

[0063] In specific implementation, a super blowing isolation airway module 2 is arranged between the blowing reed plate 3 and the blowing cover plate 1. The linearly arranged super blowing isolation airways formed between the super blowing isolation airway module 2 and the blowing reed plate 3 enable each sound hole 7 to have an independent super blowing isolation airway, which is isolated from adjacent super blowing isolation airways. At the same time, since the air outlet holes of the super blowing isolation airways are at the rear of the harmonica, that is, when performing super blowing, straighten the middle finger or index finger of the right hand and lean it on the air outlet holes of the super blowing isolation airways at the rear of the harmonica, block the air outlet holes, and blow air towards the sound holes of the harmonica to blow the blowing reed piece 11 of the sound hole to sound, and the super blowing sound of the air hole can be emitted. The operation is simple, convenient for playing, and consistent with the traditional harmonica holding action.

[0064] To ensure airtightness, the super blowing isolation airway module 2 is closely attached to the blowing reed plate 3. At the same time, the outlet of the partition cavity 9 in the super blowing isolation airway module 2 is flush with the rear end of the harmonica grid 4.

[0066] It further includes a blowing reed piece 11 and a suction reed piece 10. The blowing reed piece 11 is arranged on the blowing reed plate 3 and is adapted to the sound reed groove 8, and the suction reed piece 10 is arranged on the suction reed plate 5 and is adapted to the sound reed groove 8.

[0067] Furthermore, the pitch of the corresponding sound hole 7 is controlled by the thickness and length of the blowing reed piece 11 and the suction reed piece 10.

[0068] In specific implementation, the sound sequence arrangement of the blowing reed piece 11 of the blowing reed plate 3, the suction reed piece 10 of the suction reed plate 5, and the corresponding super blowing sound and bending sound:

[0070] Note: A new type of tuning arrangement full-scale harmonica with a built-in super blowing control assistor in 10 holes. For each sound hole sound (in a 10-hole full-scale harmonica, from left to right, the sound holes are successively called the 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, and 10th holes).

[0071] Embodiment 2

[0072] A new type of tuning arrangement full-scale harmonica with a built-in super blowing control assistor, including a harmonica body;

[0073] The harmonica body includes a blowing sound cover plate 1, an overblow isolation airway module 2, a blowing sound reed plate 3, a fret 4, a sounding reed plate 5, and a sounding cover plate 6. A number of linearly increasing sound holes 7 are evenly arranged along the length direction on the fret 4. Specifically, the number of the sound holes 7 can be set according to actual requirements. In the present embodiment, the number of the sound holes 7 is 10 holes.

[0074] The blowing sound reed plate 3 and the sounding reed plate 5 are respectively arranged on the upper and lower sides of the fret 4. Sound reed grooves 8 corresponding to the sound holes 7 are provided on the blowing sound reed plate 3 and the sounding reed plate 5. The overblow isolation airway module 2 is provided on the blowing sound reed plate 3. A linear arrangement of partition cavities 9 corresponding to the sound reed grooves 8 is provided in the overblow isolation airway module 2. The partition cavities 9 in the overblow isolation airway module 2 and the blowing sound reed plate 3 form an overblow isolation airway.

[0075] Specifically, the overblow isolation airway module 2 includes an isolation airway upper plate 12, an isolation airway outer side plate 13, an isolation airway bottom plate 14, and an isolation airway baffle 15. The overblow isolation airway module 2 is fixedly arranged on the upper side of the blowing sound reed plate 3.

[0076] In specific implementation, by arranging the overblow isolation airway module 2 between the blowing sound reed plate 3 and the blowing sound cover plate 1, the linearly arranged overblow isolation airway formed between the overblow isolation airway module 2 and the blowing sound reed plate 3 enables each sound hole 7 to have an independent overblow isolation airway, which is isolated from adjacent overblow isolation airways. At the same time, since the overblow isolation airway air outlet is at the rear of the harmonica, that is, when performing overblow, straighten the middle finger or index finger of the right hand and lean it on the overblow isolation airway air outlet at the rear of the harmonica, block the air outlet, and blow air into the sound hole of the harmonica to blow the blowing sound reed piece 11 of the sound hole to sound, then the overblow sound of the air hole can be emitted. The operation is simple, convenient for playing, and consistent with the traditional harmonica holding action.

[0077] To ensure airtightness, the overblow isolation airway module 2 and the blowing sound reed plate 3 are closely attached to each other. At the same time, the outlet of the partition cavity 9 in the overblow isolation airway module 2 is flush with the rear end of the fret 4.

[0078] The blowing sound cover plate 1 is arranged outside the blowing sound reed plate 3 and the overblow isolation airway module 2, and the sounding cover plate 6 is arranged outside the sounding reed plate 5.

[0079] It further includes a blowing sound reed piece 11 and a sounding reed piece 10. The blowing sound reed piece 11 is arranged on the blowing sound reed plate 3 and is adapted to the sound reed groove 8, and the sounding reed piece 10 is arranged on the sounding reed plate 5 and is adapted to the sound reed groove 8.

[0080] Furthermore, the pitch of the corresponding sound hole 7 is controlled by the thickness and length of the blowing sound reed piece 11 and the sounding reed piece 10.

[0081] In specific implementation, the sequence arrangement of the blowing reed pieces 11 of the blowing reed plate 3 and the sucking reed pieces 10 of the sucking reed plate 5, as well as the corresponding overblowing sounds and bending sounds:

[0082] Overblowing sound #2 #5 #2 #4 #2 #4 7b Blowing sound 1 3 6 1 3 5 7b 1 3 5 Hole position 1 2 3 4 5 6 7 8 9 10 Sound absorption 2 5 7 2 4 6 7 2 4 6 Suction pressure bending 2b 5b、4 7b 2b 6b 2b 6b

[0083] Note: Based on the 10-hole Paddy-tuned diatonic harmonica, the tuning arrangement of the reed tones of each sound hole is as follows: (For a 10-hole diatonic harmonica, from left to right, the sound holes are successively called the 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, and 10th holes).

[0084] During use, if you want to play the effect of the main chord for multi-hole blowing sounds in the low pitch range, when blowing the multi-hole blowing sounds and chord sounds in the middle and low pitch ranges, you can bend the middle finger of the right hand holding the harmonica so that the second joint of the bent middle finger just blocks the third hole of the overblowing isolation air outlet at the rear of the harmonica, blocking the third hole that emits the 6 sound, and emitting the main chord sounds of 1, 3, and 5.

[0085] The feature of this second embodiment is that it can play blues-style music using the second position of the harmonica.

[0086] Using the side of the bent middle finger of the left hand holding the harmonica, the air outlet of the second hole can be blocked. When playing the harmony in the low pitch range, the chords of 1, 3, 1, 3, 5 can be blown. When the air outlet of the second hole is released, the chords of 1, 3, 6, 1, 3 can be blown.

[0087] It not only retains the traditional chord playing methods of the main chord and the subdominant chord in the low pitch range during the performance of the second position of the blues harmonica, but also can play the major main chord and the minor main chord of the first position. At the same time, double-tone techniques can be performed, 13, 25, 57, 61, 72, 13, 24, 35, 46, 5b7, 1351 (blocking the air outlet of the 7th hole with the side of the left middle finger), greatly expanding the expressiveness of the harmonica.

[0090] The harmonica body includes a blowing cover plate 1, an overblowing isolation airway module 2, a blowing reed plate 3, a harmonica grille 4, a sucking reed plate 5, and a sucking cover plate 6. A number of linearly increasing sound holes 7 are evenly arranged along the length direction on the harmonica grille 4. Specifically, the number of the sound holes 7 can be set according to actual needs. In this embodiment, the number of the sound holes 7 is 10 holes.

[0091] On the upper and lower sides of the fret 4, there are respectively a blowing reed plate 3 and a sound-absorbing reed plate 5. On the blowing reed plate 3 and the sound-absorbing reed plate 5, there are reed grooves 8 corresponding to the sound holes 7. On the blowing reed plate 3, there is a super blowing isolation airway module 2. Inside the super blowing isolation airway module 2, there are partition chambers 9 arranged linearly and corresponding to the reed grooves 8. The partition chambers 9 in the super blowing isolation airway module 2 and the blowing reed plate 3 form a super blowing isolation airway;

[0092] Specifically, the super blowing isolation airway module 2 includes an isolation airway upper plate 12, an isolation airway outer plate 13, an isolation airway bottom plate 14, and an isolation airway baffle 15. The super blowing isolation airway module 2 is fixedly arranged on the upper side of the blowing reed plate 3.

[0093] In specific implementation, by arranging the super blowing isolation airway module 2 between the blowing reed plate 3 and the blowing cover plate 1, the linearly arranged super blowing isolation airway formed between the super blowing isolation airway module 2 and the blowing reed plate 3 enables each sound hole 7 to have an independent super blowing isolation airway, which is isolated from the adjacent super blowing isolation airways. At the same time, since the air outlet holes of the super blowing isolation airway are at the rear of the harmonica, that is, when doing super blowing, straighten the middle finger or index finger of the right hand, lean on the air outlet holes of the super blowing isolation airway at the rear of the harmonica, block the air outlet holes, and blow air towards the sound holes of the harmonica to blow the blowing reed piece 11 of the sound hole to sound, then the super blowing sound of this air hole can be emitted. The operation is simple, convenient for playing, and consistent with the traditional harmonica-holding action.

[0094] To ensure airtightness, the super blowing isolation airway module 2 is closely attached to the blowing reed plate 3. At the same time, the outlet of the partition chamber 9 in the super blowing isolation airway module 2 is flush with the rear end of the fret 4.

[0095] A blowing cover plate 1 is arranged outside the blowing reed plate 3 and the super blowing isolation airway module 2, and a sound-absorbing cover plate 6 is arranged outside the sound-absorbing reed plate 5;

[0096] It further includes a blowing reed piece 11 and a sound-absorbing reed piece 10. The blowing reed piece 11 is arranged on the blowing reed plate 3 and is adapted to the reed groove 8, and the sound-absorbing reed piece 10 is arranged on the sound-absorbing reed plate 5 and is adapted to the reed groove 8.

[0097] Furthermore, by controlling the thickness and length of the blowing reed piece 11 and the sound-absorbing reed piece 10, the pitch of the corresponding sound hole 7 is controlled.

[0098] In specific implementation, the sound sequence arrangement of the blowing reed piece 11 of the blowing reed plate 3, the sound-absorbing reed piece 10 of the sound-absorbing reed plate 5, and the corresponding super blowing sound and bending sound:

[0099] Overblowing sound #2 #5 #2 #4 #2 #4 7b Blowing sound 1 3 5 1 3 5 7b 1 3 5 Hole position 1 2 3 4 5 6 7 8 9 10 Sound absorption 2 5 7 2 4 6 7 2 4 6 Suction pressure bending 2b 5b、4 6b, 6, 7b 2b 6b 2b 6b

[0100] This embodiment upgrades the functions of a 10-hole classical blues Richter-tuned diatonic harmonica. On the basis of retaining the basic functions and playing methods of a 10-hole classical blues Richter-tuned diatonic harmonica, it is convenient to play overblown semitones and can precisely control the timbre decoration of overblown notes, improving the playing performance ability of the blues harmonica.

[0101] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
