The operation element 10 is a button-type operation element that is operated when the user makes a finger or the like contact with the contact member 11 and pushes it downward. In FIG. 5, a charging terminal 72 is shown. The charging terminal 72 is a terminal for charging a battery that supplies power to a circuit to be described later. In FIG. 3, arrow VI-VI passing through the center of the spray port 4 is shown.

  FIG. 6 shows a cross section of the spray device 1 as seen in the direction of arrows VI-VI. The spray device 1 includes an operation element 10, a storage unit 20, an air supply unit 30, a flow path 40, a valve 50, a control unit 60, and a power supply unit 70. The operation element 10 includes a contact member 11, a push-down member 12, a wiring member 13, and a contact sensor 14. The storage unit 20 includes a storage tank 21 and a cap 22. The air supply unit 30 includes a male connection cylinder part 31, a female connection cylinder part 32, a compressor 33, and a gas passage 34.

The power supply unit 70 includes a battery 71 and a charging terminal 72.

  The storage tank 21 has a replenishing port covered with a cap 22 on the upper side, and stores liquid such as cosmetic liquid replenished from the replenishing port. The lower side of the storage tank 21 is connected to the liquid reservoir 41. The liquid reservoir 41 is a space where the liquid stored in the storage tank 21 flows down and accumulates. The liquid reservoir 41 is connected to the liquid passage 42. The liquid passage 42 is a passage that guides the liquid accumulated in the liquid reservoir 41 to the spray port 4. The flow path 40 includes a liquid reservoir 41 and a liquid passage 42, thereby guiding the liquid from the storage unit 20 to the spray port 4.

  The compressor 33 is a device that compresses gas (usually air) and sends out the compressed gas. The compressor 33 is connected to the male connecting cylinder 31, and the gas compressed by the compressor 33 is supplied to the gas passage 34 through the male connecting cylinder 31 and the female connecting cylinder 32. The gas passage 34 is a passage that guides gas, and has one end connected to the female connection cylinder portion 32 and the other end connected to the spray port 4. The air supply unit 30 includes a male connection tube portion 31, a female connection tube portion 32, a compressor 33, and a gas passage 34, thereby compressing the gas and supplying the compressed gas to the spray port 4.

  The battery 71 is electrically connected to the charging terminal 72 and stores electric power supplied from the external power source via the charging terminal 72. The battery 71 is also electrically connected to the circuit board 61 and supplies the stored power to the circuit board 61. The circuit board 61 is a circuit that controls the operation of the compressor 33. The circuit board 61 has a switch for switching the presence or absence of power supply to the compressor 33. By switching the switch on (with power supply) and off (without power supply), the compressor 33 starts gas compression and Control termination.

  The wiring member 62 has a conductive wire, for example, and functions as a wiring that electrically connects the circuit board 61 and the wiring member 13 of the operation element 10 that enters the air supply body 2 through the through hole 5. If the air supply body 2 and the ejection head 3 are connected, the wiring member 62 can be connected to the circuit board 61 and the wiring member 13 even when the operation element 10 is not operated, that is, the operation element 10 is not pushed downward. Are arranged to be electrically connected. The wiring member 13 is connected to the contact member 11, and the circuit board 61 always supplies power to the contact sensor 14 via the wiring member 62 and the wiring member 13. Note that these wiring members are not limited to those having conductive wires, and for example, the whole member may be electrically conductive and electrically connect each part.

  The contact sensor 14 is a sensor that detects a user's contact with the operation element 10, and is provided on the contact member 11. As the contact sensor 14, for example, a touch sensor (a capacitance sensor, a resistance film sensor, an infrared sensor, etc.) is used, but is not limited thereto, and is a pressure sensor (a contact is detected by a change in pressure) or a temperature sensor. (A contact is detected by a change in temperature) or the like may be used. The contact sensor 14 supplies a signal indicating whether or not the user has touched the operation element 10 to the circuit board 61 via the wiring member 62 and the wiring member 13.

  The circuit board 61 determines the presence or absence of a user's contact with the operation element 10 from the supplied signal. When it is determined that there is a contact, the circuit board 61 turns on the switch and supplies power to the compressor 33 to compress the gas. To start. In this way, the control unit 60 determines that the user has touched the operating element 10 when the contact sensor 14 detects the user's contact, and activates the air supply unit 30.

The valve 50 opens and closes the flow path 40 in response to an operation on the operation element 10. The valve 50 will be described with reference to FIG.
FIG. 7 is an enlarged view of a portion X1 in FIG. The valve 50 includes a needle 51, a needle support portion 52, a spring 53, a lever portion 54, and a power conversion portion 55. The needle 51 is a needle-shaped member with a thin tip, and when the operation element 10 is not operated, the tip is inserted into the spray port 4 and the spray port 4 is closed as shown in FIG. To.

  More specifically, the spray port 4 is provided with a gas outlet 341 that is the end of the gas passage 34 and a liquid outlet 421 that is also the end of the liquid passage 42 inside. The needle 51 closes both the gas outlet 341 and the liquid outlet 421 when the operation element 10 is not operated.

  The needle support portion 52 supports the rear end (the end opposite to the tip) of the needle 51. The spring 53 biases (applies a force) to the needle support portion 52 in the closing direction A1 in which the needle 51 closes the spray port 4. The closing direction A1 is a direction from the rear end of the needle 51 toward the tip.

  The lever portion 54 is provided so as to be rotatable about a shaft 541, and an end portion 542 away from the shaft 541 is in contact with the lower side of the push-down member 12 of the operation element 10. The lever portion 54 is biased in a direction in which the end portion 542 pushes the push-down member 12 upward by biasing means such as a spring (not shown).

  The push-down member 12 is fixed to the wiring member 13, and the wiring member 13 is fixed to the contact member 11. When the user touches the contact member 11 and performs an operation of pushing down the operation element 10, the push-down member 12 moves downward and pushes down the end 542 of the lever portion 54 downward. When the end portion 542 is pushed downward, the lever portion 54 rotates about the shaft 541.

  The power conversion unit 55 is provided so as to contact the lever unit 54 and the needle support unit 52. When the lever portion 54 rotates, the power conversion portion 55 uses the rotational force to rotate the needle support portion 52 in a direction opposite to the closing direction A1, that is, the needle 51 is retracted from the spray port 4 and the gas outlet 341 and liquid. It converts into the force urged | biased in the opening direction A2 which opens the exit 421. Therefore, when the operation element 10 is depressed, a force for depressing the operation element 10 is transmitted to the needle 51 via the lever part 54 and the power conversion part 55, and the spray port 4 is opened.

The operation from when the user operates the operation element 10 until the liquid is sprayed will be described with reference to FIGS.
FIG. 8 shows a state in which the user U1 is in contact with the operation element 10. In the state of FIG. 8, the operating element 10 has not been pushed downward yet, and the vertical position has not changed. In this state, the contact sensor 14 of the operation element 10 supplies a signal indicating the presence / absence of contact to the circuit board 61, determines that the circuit board 61 has contacted the operation element 10, and controls the compressor 33 to control the gas flow. Start compression.

  FIG. 9 shows a state in which the user U1 presses down the operation element 10. In the state of FIG. 9, the push-down member 12 of the operating element 10 rotates the lever portion 54, and the needle 51 moves in the opening direction A2 by the rotational force, and the gas outlet 341 and the liquid outlet 421 are opened, that is, the spray port 4 is opened. It is open. The opening of the liquid outlet 421 means that the liquid flows out from the liquid outlet 421. In the present embodiment, the liquid flows out from the liquid outlet 421 when the push-down member 12 is pushed down to the position shown in FIG.

  As described above, the operation element 10 is provided such that its position (vertical position) is changed by a user operation. The valve 50 opens the liquid flow path 40 when the amount of change in the position of the operator 10 reaches a predetermined value (in this embodiment, the amount of movement from the state of FIG. 8 to the state of FIG. 9). Moreover, the control part 60 operates the air supply part 30 as described in FIG. 8 before the flow path 40 is opened as shown in FIG. 9 based on the user's operation on the operator 10.

  When the gas is first compressed as in the air supply unit 30 and the compressed gas is supplied to the spray port 4, the gas is compressed between the start of gas compression and the time when the compressed gas is ejected from the spray port 4. The time required for compression will elapse. Therefore, if the flow path 40 is opened simultaneously with the start of gas compression, the liquid flowing out during the period until the compressed gas starts to be ejected from the spray port 4 accumulates outside the liquid outlet 421, which is large. It is possible that a liquid having a particle diameter is sprayed or the liquid leaks from the spray port 4.

  In the present embodiment, since the air supply unit 30 is operated before the flow path 40 is opened as described above, it is possible to wait for the time required for gas compression before the liquid flows out from the liquid outlet 421. As a result, in the device that sprays liquid with the gas compressed and ejected like the spray device 1, compared with the case where the operation of the air supply unit 30 and the opening of the flow path 40 are simultaneous, the spraying is started. The particle size of the liquid can be reduced.

  Further, in this embodiment, when the user touches the operating element 10, the air supply unit 30 is operated, so that it is not necessary to move the operating element 10 to operate the air supplying unit 30. Compared to the case where the operation member 10 needs to be moved for the operation of 30, it is possible to ensure a longer time to wait for the gas compression. Further, in this embodiment, the user can shift the operation start timing of the air supply unit 30 and the opening timing of the flow path 40 as described above only by performing one operation of pushing down the operation element 10. ing.

[2] Second Embodiment Hereinafter, a second embodiment of the present invention will be described focusing on differences from the first embodiment. In the first embodiment, the air supply unit 30 is activated when the contact sensor 14 detects the user's contact with the contact member 11. However, in the second embodiment, the air supply is performed when the Hall element detects a magnetic field. Part 30 is activated.

  FIG. 10 shows a cross section of the spraying device 1a of the second embodiment. The spray device 1a includes an operation element 10a provided inside the ejection head 3a and a control unit 60a provided inside the air supply body 2a. The operation element 10 a includes a contact member 11, a push-down member 12, a connecting member 15, and a magnet 16. The control unit 60 a includes a circuit board 61 and a magnetic sensor 63. The connecting member 15 is a member that connects the contact member 11, the push-down member 12, and the magnet 16.

  The connecting member 15 is an elongate member whose longitudinal direction is the vertical direction, and the contact member 11 is fixed to the upper end and the magnet 16 is fixed to the lower end. Further, the push-down member 12 is fixed closer to the lower end than to the upper end. The magnet 16 is a magnetic field generating member that generates a magnetic field, for example, a permanent magnet.

  The magnetic sensor 63 is a sensor that measures the strength of the magnetic field, and is, for example, a Hall element (a magnetic sensor other than the Hall element may be used). The magnetic sensor 63 supplies a signal indicating the measured magnetic field strength to the circuit board 61. The circuit board 61 calculates the distance between the magnet 16 and the magnetic sensor 63 based on the strength of the magnetic field indicated by the supplied signal.

  FIG. 11 is an enlarged view of the portion X2 in FIG. FIG. 11 shows a state where the operation element 10a is not pushed downward. In this state, the magnet 16 and the magnetic sensor 63 are arranged such that the distance between them is L1. When this distance approaches L2, which is smaller than L1, the circuit board 61 determines that the operation element 10a has been operated, and controls the compressor 33 to start gas compression.

  FIG. 12 shows a state in which the operation element 10a is operated. FIG. 12 shows a state in which the user U1 presses down the operation element 10a by L2 (L1 <L2). In this state, the circuit board 61 determines that the distance between the magnet 16 and the magnetic sensor 63 has approached L2 based on the signal supplied from the magnetic sensor 63, and controls the compressor 33 to start gas compression.

  Thus, the control unit 60a operates the air supply unit 30 when the strength of the magnetic field measured by the magnetic sensor 63 reaches a predetermined value (the strength at which the distance between the magnet 16 and the magnetic sensor 63 is calculated as L2). . At this time, since the magnet 16 and the magnetic sensor 63 may be separated from each other, it is not necessary to move the magnet 16 provided at the lower end of the operation element 10a to the inside of the air supply body 2a. Therefore, the air supply body 2a is not provided with a hole such as the through hole 5 shown in FIG. 1, and the air supply body is provided with a hole according to the position and size of the operation element as in the through hole 5. Compared to the case, the processing of the air supply body is easier.

  On the other hand, the push-down member 12 is also pushed down by L2, and the lever portion 54 is rotated. In this state, the needle 51 is not moved in the opening direction A2 to the extent that the liquid flows out from the liquid outlet 421. . Therefore, in the state of FIG. 12, the flow path 40 is not yet opened, and the spraying from the spraying port 4 is not started.

  FIG. 13 shows a state in which the operation to the operation element 10a has further progressed. FIG. 13 shows a state in which the user U1 presses down the operation element 10a by L3 (L2 <L3). In this embodiment, in this state, the needle 51 moves in the opening direction A2 so that the outflow of the liquid from the liquid outlet 421 is started, and the flow path 40 is opened.

  As described above, in the present embodiment, when the valve 50 reaches the first amount (L1-L3, which is the amount of movement from the state of FIG. 11 to the state of FIG. 13), the flow of the operation element 10a flows. The path 40 is opened. When the control unit 60a reaches the second amount (L1-L2 which is the movement amount from the state of FIG. 11 to the state of FIG. 12), the amount of change in the position of the operation element 10a is smaller than the first amount. The air supply unit 30 is operated.

  In the present embodiment, the magnetic sensor 63 provided in the air supply body 2a may be electrically connected to the circuit board 61 provided in the same air supply body 2a, so that the contact member 11 is provided as in the first embodiment. Compared to the case where the contact sensor 14 provided in the ejection head 3a is electrically connected to the circuit board 61 in order to detect the contact, the wiring can be reduced. Also in the present embodiment, the operation start timing of the air supply unit 30 and the opening timing of the flow path 40 can be shifted as described above only by the user performing one operation of pushing down the operation element 10a. ing.

[3] Modifications Each of the above-described embodiments is merely an example of the present invention and may be modified as follows. Moreover, you may implement each Example and each modification in combination as needed.

[3-1] Beauty device In each of the above-described embodiments, the spray device has been described. However, the present invention may be applied as a beauty device that uses cosmetics as the liquid stored in the spray device and the storage unit 20. . The cosmetics herein include those used for skin care, make-up, hair care, and other uses (skin lotion, cosmetic liquid, etc.), as well as those for enjoying perfume and eau de cologne.

[3-2] Operation start timing of air supply unit and opening timing of flow path In the first embodiment, the contact sensor 14 detects contact with the contact member 11, and the magnetic sensor 63 measures in the second embodiment. By judging the strength of the magnetic field in two stages, the operation start timing of the air supply unit 30 and the opening timing of the flow path 40 are shifted, but the method of shifting both timings is not limited thereto.

  For example, in the second embodiment, the distance from the operator may be measured using an infrared sensor or an ultrasonic sensor instead of the magnetic sensor. Further, when the operation element is kept in contact with the switch of the circuit board 61 and the operation element is operated and pressed down slightly, the switch is turned on before the flow path 40 is opened, and the circuit board 61 is supplied with air. You may make it operate a part.

  Further, when the user operates the operation element, a mechanism is employed in which a driving device such as a motor controlled by the circuit board 61 is activated to open the flow path 40, and the circuit board 61 is fed so as to shift the above two timings. The air unit 30 and the driving device may be controlled. In short, it is only necessary that the control unit including the circuit board 61 operates the air supply unit 30 before the flow path 40 is opened based on an operation on the operation element.

[3-3] Operator In the above embodiment, a button-type operator that is pushed down by the user is used. However, the present invention is not limited to this. For example, it may be a button-type operator that pushes in the horizontal direction, a lever-type switch, a knob-type switch that rotates the knob, a rocker switch that switches on and off by alternately pressing both ends of the operation button, etc. Good.

  In short, the operation element only needs to change its position or orientation when operated by the user. In any case, for example, a valve provided in the spray device as in the first embodiment opens the flow path 40 in accordance with the amount of change in the position or orientation of the operation element, and as in the second embodiment, When the amount of change reaches the first amount, the valve opens the flow path 40, and when the amount of change reaches the second amount, the air supply unit 30 is operated.

Further, the operation element may be divided into an opening / closing operation element that opens and closes the flow path 40 by moving the valve 50 and an air supply operation element that operates the air supply unit 30 to start gas compression.
FIG. 14 shows the spraying apparatus 1b of this modification as seen from the side and the back. The spraying device 1b includes an air supply body 2b and an operation element 10b. The operation element 10b includes an opening / closing operation element 17 and an air supply operation element 18.

  The opening / closing operator 17 includes a contact member 11 and a push-down member 12 shown in FIG. When the opening / closing operator 17 is pushed down by a user operation, the valve 50 opens the flow path 40 when the amount of change in the position of the opening / closing operator 17 reaches a predetermined value. The opening / closing operator 17 is a portion whose position is changed by an operation of the operator 10b, and is an example of the “first portion” in the present invention. Note that the opening / closing operator may be a portion whose direction is changed by an operation, or may be a portion where both the position and the direction are changed. The opening / closing operator 17 does not include the wiring member 13 and the contact sensor 14 illustrated in FIG. 6.

  The air supply operator 18 is a portion of the operator 10b whose position and orientation are not changed by an operation, and is an example of the “second portion” in the present invention. The air supply operator 18 is provided with a contact sensor 19. The contact sensor 19 detects the user's contact with the operation element 10b (of which the air supply operation element 18 is included). The contact sensor 19 is electrically connected to the circuit board 61 shown in FIG. 6, and supplies a signal indicating whether or not the user has touched the sensor to the circuit board 61. Thereby, similarly to the embodiment, when the contact of the user is detected by the contact sensor 19, the control unit 60 determines that the user has touched the operation element 10 b and activates the air supply unit 30.

  The air supply operator 18 is provided on the back side of the air supply main body 2b (on the back side when the side where the spray port 4 is provided is the front of the spray device 1b) and above the charging terminal 72. For example, when the user has the spray device 1b to operate the opening / closing operator 17 with the index finger, the palm of the user covers the back side of the air supply body 2b. The user's hand comes into contact with the contact sensor 19. In this way, the air supply operator 18 is provided at a position where the hand of the user holding the own device touches the spraying operation.

  The position of the air supply operator is not limited to this. The air supply operator may be provided, for example, on the side surface side of the air supply main body, or may be provided on the back side of the spray head. These positions are also touched by the user's hand holding his / her own device to perform the spraying operation. In either case, the user's hand who is going to operate the opening / closing operator touches the contact sensor provided on the air supply operator. In this modification, the user's hand touches the contact sensor before the user starts an operation on the opening / closing operator, so that the air supply unit is compared with the case where the opening / closing operator is provided with a contact sensor.
