The left and right side portions can be sandwiched and held between the fingertips without obstruction, thereby improving the operability during attachment and removal.
図5~図8に示すようにバッテリ30は、概ね直方体形状のバッテリケース30g内に10本のセル30h~30hを収容したバッテリパックで、その上面には、左右一対のレール受け部30a,30aが設けられている。両レール受け部30a,30a間には、正負の端子受け部30b,30cが配置されている。正負の端子受け部30b,30c間には、充電器で充電する際に当該充電器との間で制御信号を送受信するためのコネクタ部30dを備えている。また、バッテリ30の上面後部には、ロック爪部30eが設けられている。このロック爪部30eは圧縮ばね30iにより上方へ突き出す方向にばね付勢されている。このロック爪部30eは、後面に設けたアンロックボタン30fを指先で押し下げ操作することによりばね付勢力に抗して下方のアンロック位置に移動させることができる。
As shown in FIGS. 5 to 8, the battery 30 is a battery pack in which 10 cells 30h to 30h are accommodated in a substantially rectangular parallelepiped battery case 30g, and a pair of left and right rail receiving portions 30a and 30a are provided on the upper surface thereof. Is provided. Positive and negative terminal receiving portions 30b and 30c are arranged between the rail receiving portions 30a and 30a. Between the positive / negative terminal receiving parts 30b and 30c, when charging with a charger, a connector part 30d for transmitting and receiving a control signal to and from the charger is provided. Further, a lock claw portion 30 e is provided at the rear upper surface of the battery 30. The lock claw 30e is spring-biased in a direction protruding upward by a compression spring 30i. The lock claw portion 30e can be moved to a lower unlock position against a spring biasing force by pushing down an unlock button 30f provided on the rear surface with a fingertip.
図9に示すように両バッテリ取り付け部34,34は、相互に同様の構成を備えている。このバッテリ取り付け部34には、左右一対のレール部34a,34aが設けられている。両レール部34a,34a間には、正負の接続端子34b,34cが配置されている。両バッテリ取り付け部34,34の図示上部には、それぞれバッテリ30のロック爪部30eが嵌り込むロック係合部(係合凹部)34eが設けられている。また、両バッテリ取り付け部34,34の図示下部には、それぞれ取り付けたバッテリ30を取り外し方向に付勢するための付勢部材34dが設けられている。本実施形態では、付勢部材34dとしてリーフスプリング(板ばね)が用いられている。バッテリ30を取り外す際にアンロックボタン30fを押し下げ操作すると、当該バッテリ30がこの付勢部材34dの付勢力により取り出し方向に変位(ポップアップ)される。このため、使用者は狭いスペースであってもバッテリを確実に把持して楽に取り外すことができる。
As shown in FIG. 9, both battery mounting portions 34 and 34 have the same configuration. The battery mounting portion 34 is provided with a pair of left and right rail portions 34a and 34a. Positive and negative connection terminals 34b and 34c are disposed between the rail portions 34a and 34a. Lock engaging portions (engaging recesses) 34e into which the lock claws 30e of the battery 30 are fitted are provided on the upper portions of the battery mounting portions 34, 34 in the figure. Further, urging members 34d for urging the attached batteries 30 in the detaching direction are provided at the lower portions of the battery attachment portions 34, 34 in the figure. In the present embodiment, a leaf spring (plate spring) is used as the urging member 34d. When the unlock button 30f is pushed down when removing the battery 30, the battery 30 is displaced (popped up) in the take-out direction by the urging force of the urging member 34d. For this reason, even in a narrow space, the user can securely grasp the battery and easily remove it.
図9に示すようにバッテリ取り付け部34に対してバッテリ30を図示下方へスライド(平行移動)させつつそのレール受け部30a,30aをレール部34a,34aに係合させることにより当該バッテリ30をバッテリ取り付け部34に対して機械的に結合することができる。バッテリ30がバッテリ取り付け部34に機械的に結合されると、同時にバッテリ取り付け部34側の接続端子34b,34cがバッテリ30側の端子受け部30b,30cに進入して電気的に接続される。また、バッテリ30がバッテリ取り付け部34に対して機械的に結合されると、ロック爪部30eがロック係合部34e内に弾性的に嵌り込んで当該バッテリ30がスライド方向移動不能に固定された取り付け状態にロックされる。
As shown in FIG. 9, while the battery 30 is slid downward (parallel movement) with respect to the battery mounting portion 34, the rail receiving portions 30a and 30a are engaged with the rail portions 34a and 34a, thereby making the battery 30 into the battery. It can be mechanically coupled to the attachment 34. When the battery 30 is mechanically coupled to the battery mounting portion 34, the connection terminals 34 b and 34 c on the battery mounting portion 34 side simultaneously enter the terminal receiving portions 30 b and 30 c on the battery 30 side and are electrically connected. Further, when the battery 30 is mechanically coupled to the battery mounting portion 34, the lock claw portion 30e is elastically fitted into the lock engagement portion 34e, and the battery 30 is fixed so as not to move in the sliding direction. Locked to the installed state.
取り付けたバッテリ30をバッテリ取り付け部34から取り外す際には、アンロックボタン30fを押し下げ操作すれば取り出し方向にポップアップされることからそのまま把持して図9において上方へ引き抜けばよい。これによりレール受け部30a,30aがレール部34a,34aから外れ、接続端子34b,34cが端子受け部30b,30cから離脱してバッテリ30がバッテリ取り付け部34から取り外される。
When removing the attached battery 30 from the battery attachment portion 34, if the unlock button 30f is pushed down, it pops up in the take-out direction, so that it can be gripped as it is and pulled upward in FIG. As a result, the rail receiving portions 30a and 30a are detached from the rail portions 34a and 34a, the connection terminals 34b and 34c are detached from the terminal receiving portions 30b and 30c, and the battery 30 is removed from the battery mounting portion 34.
前記したように第1実施形態の場合は、バッテリ収納部31の左側部に設けた開閉扉32を開放して、2個のバッテリ30,30をバッテリ取り付け部34,34に取り付けることができ、逆に取り外すことができる。図2に示すようにバッテリ取り付け部34,34は、バッテリ収容部31の内方(平面的に見て中央)に向かって下る方向に沿って配置されている。このため、2個のバッテリ30,30は、その上面を上側にして図2中白抜き矢印で示すように斜め下方へ向けて押し込むようにしてスライドさせることによりバッテリ取り付け部34,34に取り付けられ、逆に斜め上方(白抜き矢印とは逆方向)へ引き出すようにしてスライドさせることによりバッテリ取り付け部34,34から取り外すことができる。このように取り付け、取り外し方向を上下に傾斜させた方向とすることにより、使用者はバッテリ30,30のバッテリ取り付け部34,34に対する取り付け、取り外し操作を楽に行うことができる。
As described above, in the case of the first embodiment, the open / close door 32 provided on the left side of the battery storage unit 31 can be opened to attach the two batteries 30, 30 to the battery mounting units 34, 34. Conversely, it can be removed. As shown in FIG. 2, the battery attachment portions 34, 34 are arranged along a direction descending inward (center as viewed in plan) of the battery housing portion 31. For this reason, the two batteries 30 and 30 are attached to the battery attachment portions 34 and 34 by sliding the two batteries 30 and 30 so that the upper surface thereof is on the upper side and as shown in FIG. On the contrary, it can be removed from the battery mounting portions 34, 34 by sliding it so as to be drawn obliquely upward (in the direction opposite to the white arrow). In this way, the user can easily attach and remove the batteries 30 and 30 to and from the battery attaching portions 34 and 34 by setting the attaching and detaching directions to be inclined upward and downward.
バッテリ30のバッテリ取り付け部34に対する取り付け、取り外しは、図1及び図2に示すように当該バッテリ30の取り付け方向後面(アンロックボタン30f側)に親指をあてがい、前面にその他の指先をあてがって片手Hで下から受ける状態に保持して行うことができる。これにより2個のバッテリ30,30を迅速かつ楽に取り付け、取り外すことができる。
As shown in FIGS. 1 and 2, the battery 30 is attached to or detached from the battery attachment portion 34 by placing a thumb on the rear surface (unlock button 30 f side) in the direction of attachment of the battery 30 and placing another fingertip on the front. It can be carried out by holding in a state of receiving from below with H. Thereby, the two batteries 30 and 30 can be attached and removed quickly and easily.
2個のバッテリ30,30をバッテリ収容部31内に取り付けた状態では、当該2個のバッテリ30,30は比較的重量物である吐出ポンプ20の主としてポンプモータ21の直下に配置されている。
In a state in which the two batteries 30 and 30 are mounted in the battery housing 31, the two batteries 30 and 30 are disposed mainly directly below the pump motor 21 of the discharge pump 20 that is a relatively heavy object.
また、図2に示すように2個のバッテリ30,30をバッテリ収容部31内に取り付けた状態における当該噴霧器1の重心Gが、左右幅W方向について一定の領域E内に位置するようにバッテリ取り付け部34,34の左右幅W方向の位置が設定されている。この一定の領域Eは、当該噴霧器1の左右幅W方向中心の基準線Jを中心にして左右幅W方向それぞれ20パーセント(0.2W)の領域に跨る範囲に設定されている。しかも、貯蔵タンク10は基準線Jに対して左右対称形状を有していることから貯蔵した噴霧液の量に関係なく(満杯状態と空の状態の双方において)この重心Gの左右幅W方向の位置は領域E内に位置することとなる。これにより、当該噴霧器1を背中に背負った使用者は、貯蔵タンク10内の噴霧液の量に関係なく常時左右幅W方向の重量バランスをとった状態で(左右一方に傾くことなく)背負うことができ、この点で当該噴霧器1の取り扱い性及び操作性が確保されている。
Further, as shown in FIG. 2, the battery is arranged such that the center of gravity G of the nebulizer 1 in a state where the two batteries 30, 30 are mounted in the battery housing portion 31 is located in a certain region E in the left-right width W direction. The positions of the attachment portions 34, 34 in the left-right width W direction are set. This fixed region E is set to a range that spans a region of 20 percent (0.2 W) in each of the left and right width W directions with the reference line J at the center in the left and right width W direction of the sprayer 1 as the center. In addition, since the storage tank 10 has a symmetrical shape with respect to the reference line J, the lateral width W direction of the center of gravity G regardless of the amount of sprayed liquid stored (both full and empty). Is located within the region E. As a result, the user who carries the sprayer 1 on his / her back will always carry the weight balance in the left / right width W direction (without tilting to the left or right) regardless of the amount of spray liquid in the storage tank 10. In this respect, handling and operability of the sprayer 1 are ensured.
このように当該噴霧器1の幅方向について重心Gを基準線J上に位置させることが左右の重量バランスの観点から最も望ましいのであるが、現実には基準線Jに対して重心Gが左方又は右方にずれる場合があり、この場合であっても基準線Jから左方又は右方にそれぞれ幅Wの20パーセントの範囲内に位置させることにより、実質的に左右の良好な重量バランスを確保することができる。
As described above, it is most desirable from the viewpoint of weight balance between the left and right sides to position the center of gravity G on the reference line J in the width direction of the sprayer 1. Even in this case, the left and right sides of the reference line J are positioned within 20 percent of the width W to ensure a substantially good weight balance between the left and right sides. can do.
2個のバッテリ30,30の合計重量と、吐出ポンプ20の重量と比較して、より重い方を下側に配置し、また使用者の背中側に配置することにより、使用者はより安定した姿勢で楽に背負うことができ、この点で当該噴霧器1の取り扱い性を一層高めることができる。この観点から、第1実施形態では、より重い2個のバッテリ30,30が吐出ポンプ20に対して下方に取り付けられ、かつ前側(使用者の背中側)に配置された構成となっている。
Compared to the total weight of the two batteries 30 and 30 and the weight of the discharge pump 20, the heavier one is placed on the lower side, and the user is more stable by placing it on the user's back side. It can be easily carried in the posture, and the handling of the sprayer 1 can be further enhanced in this respect. From this viewpoint, in the first embodiment, two heavier batteries 30 and 30 are attached to the lower side with respect to the discharge pump 20 and are arranged on the front side (the back side of the user).
また、前後に横並び状態に取り付けられた2個のバッテリ30,30間には指先を進入できる程度の約15ミリメートルの隙間があくよう当該両バッテリ30,30の取り付け位置が設定されていることから、使用者はバッテリ30の左右側部を指先で挟んで保持しつつ当該バッテリ30を楽に取り付け、取り外しすることができる。なお、バッテリケースの容積が200cm3以上の大形のバッテリの場合には、上記の間隔を15ミリメートよりも小さくしてより接近した状態で複数個のバッテリを取り付ける構成とすることにより、当該複数個の大形のバッテリをバッテリ収容部内によりコンパクトに収容することができる。
In addition, the attachment positions of the batteries 30 and 30 are set so that a gap of about 15 millimeters is provided between the two batteries 30 and 30 attached side by side in front and back so that a fingertip can enter. The user can easily attach and remove the battery 30 while holding the left and right sides of the battery 30 with the fingertips. In the case of a large battery having a battery case volume of 200 cm 3 or more, the plurality of batteries can be attached in a state in which the distance is smaller than 15 mm and closer to each other. One large battery can be accommodated more compactly in the battery accommodating portion.
以上のように構成した第1実施形態の噴霧器1によれば、定格電圧36Vのポンプモータ21を駆動源とする36V仕様の噴霧器1を、1個の36Vバッテリではなく2個の18Vバッテリ30,30を取り付けて利用することができる。このことから、使用者は18V仕様の電動工具用の電源として既に所有している18Vバッテリ30,30を当該噴霧器1の電源として流用することができ、これにより当該噴霧器1の利便性及び取り扱い性を一層高めることができる。
According to the sprayer 1 of 1st Embodiment comprised as mentioned above, the 36V specification sprayer 1 which uses the pump motor 21 of the rated voltage 36V as a drive source is replaced with two 18V batteries 30 instead of one 36V battery, 30 can be attached and used. From this, the user can divert the 18V batteries 30 and 30 already owned as the power source for the 18V-specific power tool as the power source of the sprayer 1, thereby making the sprayer 1 convenient and easy to handle. Can be further enhanced.
図10及び図11には、第2実施形態の噴霧器2が示されている。第2実施形態の噴霧器2は、2個のバッテリ30,30の取り付け位置及び取り付け方向が第1実施形態とは異なっている。その他第1実施形態と同様の部材及び構成については同位の符号を用いてその説明を省略する。
10 and 11 show the sprayer 2 of the second embodiment. The sprayer 2 of the second embodiment is different from the first embodiment in the mounting position and mounting direction of the two batteries 30 and 30. Other members and configurations similar to those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.
第2実施形態では、2個のバッテリ30,30は、貯蔵タンク40と吐出ポンプ20(ポンプハウジング24)と間に取り付けられている。第2実施形態の貯蔵タンク40は、その後面側下部に段付き形状の凹みが設けられている。この凹みがバッテリ収容部41となっている。また、第2実施形態の場合、ポンプハウジング24の上部にバッテリ取り付けベース33を介して2箇所のバッテリ取り付け部34,34が設けられている。
In the second embodiment, the two batteries 30 and 30 are attached between the storage tank 40 and the discharge pump 20 (pump housing 24). The storage tank 40 according to the second embodiment is provided with a stepped recess at the lower portion on the rear surface side. This recess serves as a battery housing portion 41. In the case of the second embodiment, two battery mounting portions 34, 34 are provided on the upper portion of the pump housing 24 via the battery mounting base 33.
バッテリ30を下向き(レール受け部30a,30a側を下方に向けて)に保持して、図10中白抜き矢印で示すようにバッテリ収容部41の後方から内方(前方)に向けてスライドさせることにより、各バッテリ取り付け部34に対してバッテリ30を取り付けることができる。取り外すには、第1実施形態と同様アンロックボタン30fをアンロック側(第2実施形態の場合は上側)へ押し込み操作した状態でその後部を把持して後方(図10中白抜き矢印とは逆方向)へスライドさせればよい。取り付けたバッテリ30とバッテリ収容部41の上面との間には、指先を進入させるに足る隙間43が確保されている。
The battery 30 is held downward (with the rail receiving portions 30a and 30a facing downward), and is slid from the rear of the battery accommodating portion 41 inward (forward) as indicated by the white arrow in FIG. Thus, the battery 30 can be attached to each battery attachment portion 34. To remove, as in the first embodiment, the unlock button 30f is pushed toward the unlock side (upward in the case of the second embodiment) and the rear part is gripped and rearward (the white arrow in FIG. 10 is Slide in the opposite direction). A gap 43 sufficient to allow the fingertip to enter is secured between the attached battery 30 and the upper surface of the battery housing portion 41.
第2実施形態の場合、バッテリ30のスライド方向は水平方向になっているが、第1実施形態よりも十分に高い部位に取り付ける構成であるので、バッテリ30の取り付け、取り外しの際の良好な操作性が確保されている。
In the case of the second embodiment, the sliding direction of the battery 30 is horizontal, but since it is configured to be attached to a part sufficiently higher than that of the first embodiment, a good operation at the time of attaching and removing the battery 30 Is secured.
図11に示すようにバッテリ取り付け部34,34は、基準線Jに対して左右対称に配置されている。従って、両バッテリ30,30は、基準線Jに対して左右対称に取り付けられる。このため、噴霧器2の左右幅W方向の重心Gの位置についてはバッテリ30,30を取り付けたことが影響を及ぼすことはなく、従って第1実施形態(図2参照)と同じく領域E内に位置している。
As shown in FIG. 11, the battery mounting portions 34 and 34 are arranged symmetrically with respect to the reference line J. Accordingly, both the batteries 30 and 30 are attached symmetrically with respect to the reference line J. For this reason, the position of the center of gravity G in the left-right width W direction of the sprayer 2 does not affect the attachment of the batteries 30 and 30 and is therefore located in the region E as in the first embodiment (see FIG. 2). is doing.
第2実施形態の場合、貯蔵タンク40とポンプハウジング24との間にバッテリ30,30が取り付けられており、第1実施形態におけるバッテリ収容部31(前後左右の壁部31a,31b,31c,31d及び底部31f)は省略されている。
In the case of 2nd Embodiment, the batteries 30 and 30 are attached between the storage tank 40 and the pump housing 24, and the battery accommodating part 31 (front and rear, right and left wall parts 31a, 31b, 31c, 31d in 1st Embodiment). And the bottom 31f) are omitted.
以上のように構成した第2実施形態の噴霧器2によっても、第1実施形態と同様定格電圧36Vのポンプモータ21を駆動源とする36V仕様の噴霧器2を、1個の36Vバッテリではなく2個の18Vバッテリ30,30を電源として取り付けて利用することができる。このことから、使用者は18V仕様の電動工具用の電源として既に所有している18Vバッテリ30,30を当該噴霧器1の電源として流用することができ、これにより当該噴霧器1の利便性及び取り扱い性を一層高めることができる。
Even with the sprayer 2 of the second embodiment configured as described above, two sprayers 2 of 36V specifications that use the pump motor 21 with a rated voltage of 36V as a drive source are used instead of one 36V battery as in the first embodiment. 18V batteries 30 and 30 can be used as power sources. From this, the user can divert the 18V batteries 30 and 30 already owned as the power source for the 18V-specific power tool as the power source of the sprayer 1, thereby making the sprayer 1 convenient and easy to handle. Can be further enhanced.
図12及び図13には第3実施形態の噴霧器3が示されている。この第3実施形態も、2個のバッテリ30,30の取り付け位置及び取り付け方向について第1、第2実施形態とは異なっている。第1、第2実施形態と同じ部材及び構成については同位の符号を用いてその説明を省略する。
12 and 13 show the sprayer 3 of the third embodiment. This third embodiment is also different from the first and second embodiments in the mounting position and mounting direction of the two batteries 30 and 30. About the same member and structure as 1st, 2nd embodiment, the description is abbreviate | omitted using a same code | symbol.
第3実施形態では、2個のバッテリ30,30が貯蔵タンク50の前面側に取り付けられる構成となっている。貯蔵タンク50の前面には、下方へ開放された凹み部が設けられており、この凹み部がバッテリ収容部51とされている。このバッテリ収容部51内に、バッテリ取り付けベース33を介して2つのバッテリ取り付け部34,34が左右方向に横並び状態で配置されている。バッテリ30,30は、図12,13中白抜き矢印で示すようにそれぞれバッテリ収容部51の上方から斜め下方に向けてスライドさせることにより取り付けることができる。図12に示すようにバッテリ取り付け部34,34に取り付けられた両バッテリ30,30は、バッテリ収容部51内にほぼ収容されて貯蔵タンク50により上方、左右側方及び後方を囲われた状態となり、これにより噴霧作業中等におけるバッテリ30,30の水濡れが防止されてその保護が図られるようになっている。
In the third embodiment, two batteries 30 and 30 are attached to the front side of the storage tank 50. The front surface of the storage tank 50 is provided with a recessed portion opened downward, and this recessed portion serves as a battery accommodating portion 51. In the battery accommodating part 51, two battery attachment parts 34, 34 are arranged side by side in the left-right direction via the battery attachment base 33. The batteries 30 and 30 can be attached by sliding from the upper side of the battery accommodating portion 51 obliquely downward as shown by the white arrows in FIGS. As shown in FIG. 12, both the batteries 30, 30 attached to the battery attachment portions 34, 34 are almost housed in the battery housing portion 51 and are surrounded by the storage tank 50 at the upper, left and right sides, and the rear. As a result, the batteries 30 and 30 are prevented from being wetted during the spraying operation and the like, thereby protecting them.
両バッテリ30,30は、バッテリ収容部51内に取り付けられると、その取り付け方向後部上面側の角部が貯蔵タンク50の前面から僅かにはみ出す状態となる。第3実施形態では、この両はみ出し部52,52が当該噴霧器3を背負った使用者の左右の肩甲骨付近に当たるよう両バッテリ取り付け部34,34の位置が設定されている。第3実施形態の場合、当該噴霧器3を背負った際の使用者の背中に対するクッション性を確保するために貯蔵タンク50の前面に背当てパッドを被せておくことが望ましい。バッテリ30,30のはみ出し部52,52により形成される背当てパッドの盛り上がり部を肩甲骨付近に当てることにより、使用者は当該噴霧器3を安定した姿勢で背負うことができる。
When the batteries 30 and 30 are mounted in the battery housing 51, the corners on the upper surface side in the mounting direction are slightly protruded from the front surface of the storage tank 50. In the third embodiment, the positions of the battery mounting portions 34 and 34 are set so that the protruding portions 52 and 52 are in contact with the vicinity of the left and right shoulder blades of the user carrying the sprayer 3. In the case of the third embodiment, it is desirable to put a back pad on the front surface of the storage tank 50 in order to ensure cushioning against the user's back when the sprayer 3 is carried. By placing the raised portion of the back pad formed by the protruding portions 52, 52 of the batteries 30, 30 near the scapula, the user can carry the sprayer 3 in a stable posture.
図13に示すように両バッテリ30,30は、左右幅W方向中心を通る基準線Jに対して左右対称に取り付けられる。このため、第2実施形態と同様、両バッテリ30,30を取り付けた状態で当該噴霧器3の左右幅W方向について重心Gの位置が領域E内に位置している。これにより、当該噴霧器3の左右方向の重量バランスが良好に保たれて、使用者は当該噴霧器3をより一層安定した姿勢で背負うことができる。
As shown in FIG. 13, both the batteries 30 and 30 are mounted symmetrically with respect to a reference line J passing through the center in the left-right width W direction. For this reason, as in the second embodiment, the position of the center of gravity G is located in the region E in the left-right width W direction of the sprayer 3 with both the batteries 30 and 30 attached. Thereby, the weight balance of the left-right direction of the said nebulizer 3 is maintained favorable, and the user can carry the said nebulizer 3 in the back | restored attitude | position in the more stable attitude | position.
第3実施形態によっても、使用者が既に所有している18V仕様の2個のバッテリ30,30を電源として36V仕様の噴霧器3を利用することができることから、当該噴霧器3の利便性及び取り扱い性を一層高めることができる。
Also according to the third embodiment, it is possible to use the 36V specification sprayer 3 by using two 18V specification batteries 30 and 30 already owned by the user as power sources. Can be further enhanced.
第3実施形態では、バッテリ取り付け部34,34に対してバッテリ30,30を上方から斜め下方に向けて取り付ける構成であるので、その取り付け、取り外しの際の操作を迅速かつ楽に行うことができる。但し、これに代えて第2実施形態と同じく、貯蔵タンクの前面に設けたバッテリ収容部に対してバッテリ30,30を水平にスライドさせて取り付ける構成としても、第1実施形態よりも十分に高い位置であるので、当該バッテリ30,30を取り付け、取り外しする際の操作性が良好に確保される。
In the third embodiment, since the batteries 30 and 30 are attached to the battery attachment portions 34 and 34 obliquely downward from above, operations for attachment and removal can be performed quickly and easily. However, instead of this, as in the second embodiment, the battery 30, 30 can be horizontally slid and attached to the battery housing provided on the front surface of the storage tank, which is sufficiently higher than the first embodiment. Since it is a position, the operativity at the time of attaching and removing the said batteries 30 and 30 is ensured favorably.
図14及び図15には第4実施形態の噴霧器4が示されている。第4実施形態では、第1実施形態と同様吐出ポンプ20の下方にバッテリ収容部60を備えている。但し、バッテリ30,30の取り付け、取り外し方向が第1実施形態の左側部側とは異なっている。第4実施形態では、後面側からバッテリ30,30を取り付け、取り外しする構成となっている。第1~第3実施形態と同様の部材及び構成については同位の符号を用いてその説明を省略する。
14 and 15 show a sprayer 4 according to a fourth embodiment. In 4th Embodiment, the battery accommodating part 60 is provided under the discharge pump 20 similarly to 1st Embodiment. However, the attachment and removal directions of the batteries 30 and 30 are different from the left side of the first embodiment. In the fourth embodiment, the batteries 30 and 30 are attached and removed from the rear side.

Since the operation panel 25 is disposed on the exterior of the product, the battery controller C2 is disposed along the inner surface of the product exterior.
さらに、発熱するバッテリコントローラを冷却するという観点からは、通常、ポンプを駆動するポンプモータのモータ軸に取付けられるファンによって発生する空気流に接するように配置されることが望ましい。すなわち、製品の外装を貫通する吸気孔から始まり、モータファンへ通じる空気通路、又は、モータファンから始まり、排気孔へ通じる空気通路、いずれかの通路の途中に配置されることが望ましい。この場合、より冷却されやすいモータの近傍に配置されることが望ましいことからも、上記操作パネル25の裏側であってポンプモータ21の後方に配置されることが望ましい。
Furthermore, from the viewpoint of cooling the battery controller that generates heat, it is usually desirable that the battery controller is disposed so as to be in contact with the air flow generated by the fan attached to the motor shaft of the pump motor that drives the pump. That is, it is desirable that the air passage starts from the intake hole penetrating the exterior of the product and communicates with the motor fan, or the air passage starts from the motor fan and communicates with the exhaust hole. In this case, since it is desirable to arrange in the vicinity of the motor that is more easily cooled, it is desirable to arrange it behind the operation panel 25 and behind the pump motor 21.
また、複数個のバッテリ30~30を直列的に接続する場合には、いずれか1つのバッテリ30の故障、放電によって当該噴霧器1(又は、2~7)を使用できなくなる。このため、どのバッテリ30が放電などにより停止したかを知るために、各バッテリ30の残容量の報知手段があることが望ましい。
In addition, when a plurality of batteries 30 to 30 are connected in series, the sprayer 1 (or 2 to 7) cannot be used due to a failure or discharge of any one of the batteries 30. For this reason, in order to know which battery 30 has stopped due to discharge or the like, it is desirable to have a means for notifying the remaining capacity of each battery 30.
例えば2個のバッテリ30,30の残量表示Z1,Z2の表示位置としては、使用者のバッテリ取り付け時、又は、操作パネル25の近傍に、バッテリ30の位置に対応して表示されることが望ましい。例えば、図23には、左側部の開閉扉32を開放した取り付け姿勢で2個のバッテリ30,30が前後(使用者から見て左右)に位置して見える場合には、各バッテリ30の残量表示Z1,Z2もバッテリ取り付けベース33の左側部に、あるいは操作パネル25の上側に左右に並ぶように表示されることが望ましい。残量表示Z1,Z2は、表示ボタンZbの押し操作により点灯表示する。
For example, the display positions of the remaining amount indications Z1 and Z2 of the two batteries 30 and 30 may be displayed corresponding to the position of the battery 30 when the user installs the battery or in the vicinity of the operation panel 25. desirable. For example, in FIG. 23, when the two batteries 30, 30 appear to be positioned front and rear (left and right as viewed from the user) with the left open / close door 32 opened, the remaining battery 30 is left. It is desirable that the quantity indications Z1 and Z2 are also displayed on the left side of the battery mounting base 33 or on the upper side of the operation panel 25 so as to be arranged side by side. The remaining amount displays Z1 and Z2 are turned on by pressing the display button Zb.
また、使用者への報知の方法も、上記の残量表示Z1,Z2のように複数のバーで残容量を示すものに限られず、色、点滅速度、音などで行ってもよい。
なお、バッテリが所定値を下回る残容量となった場合(駆動停止状態の場合)に、どのバッテリが原因かを示す機能(ランプの点滅、赤色表示)を備えていてもよい。 Further, the method of notifying the user is not limited to the method of indicating the remaining capacity with a plurality of bars as in the remaining amount indications Z1 and Z2, but may be performed by color, blinking speed, sound, or the like.
