By spraying liquid in a continuous flow from the nozzle and turning the continuous flow into droplets to collide with the cleaning object in the form of droplets, the cleaning effect of the cleaning object using the liquid is improved compared to a structure in which only a water column is sprayed from the nozzle. Therefore, when removing the supporting material from the three-dimensional object, it is possible to suppress the situation in which the three-dimensional object is damaged, and the supporting material can be effectively removed from the three-dimensional object.

[0029] According to this aspect, the heating unit can be controlled according to the type of the supporting material. Therefore, the performance of removing the supporting material from the three-dimensional object can be automatically improved according to the type of the supporting material.

[0030] A seventh aspect of the cleaning tool of the present invention is an aspect belonging to any one of the first to third aspects, and is characterized in that the cleaning tool includes a main body connected to the nozzle and having a flow path inside for the liquid to flow.

[0031] According to this mode, the cleaning tool includes a main body connected to the nozzle and having a flow path for liquid circulation inside. Therefore, for example, a user can hold the main body and easily cause the droplet to collide with a preferred location of the cleaning object.

[0032] A cleaning tool according to an eighth aspect of the present invention is an aspect belonging to any one of the first to third aspects, and is characterized in that the cleaning tool includes a holding portion that holds a tool different from the nozzle for removing the supporting material.

[0033] According to this method, the cleaning tool has a holding portion that holds a tool different from the nozzle for removing the support material. Therefore, since a tool different from the nozzle for removing the support material can be used, the performance of removing the support material from the three-dimensional object can be improved, and the necessity of separately preparing a structural component for holding the tool can be eliminated.

[0034] A cleaning tool according to a ninth aspect of the present invention is an aspect belonging to any one of the first to third aspects, and is characterized in that the cleaning tool includes a housing in which the nozzle is used.

[0039] According to this aspect, a circulation mechanism is provided for ejecting the liquid stored in the storage portion from the nozzle again. Therefore, the liquid ejected once from the nozzle and recovered can be reused.

[0040] A cleaning tool according to a twelfth aspect of the present invention is an aspect dependent on the ninth aspect, and is characterized in that the housing includes a temperature adjustment unit that adjusts the temperature inside the housing.

[0041] According to this aspect, the housing includes a temperature adjustment unit that adjusts the temperature inside the housing. Therefore, for example, the performance of removing the support material from the three-dimensional object can be improved.

[0042] The cleaning tool of the thirteenth embodiment of the present invention is characterized in that it comprises: a nozzle that sprays liquid in a continuous flow and makes the continuous flow droplet-like; and a pump that supplies the liquid to the nozzle. The cleaning tool removes attachments from the cleaning object by spraying the liquid from the nozzle toward the cleaning object and making the liquid collide with the cleaning object in the form of droplets.

[0043] According to this method, a nozzle that sprays liquid in a continuous flow and turns the continuous flow into droplets is used to make the liquid collide with the cleaning object in the form of droplets, thereby removing attached matter from the cleaning object. By spraying liquid in a continuous flow from the nozzle and turning the continuous flow into droplets to collide with the cleaning object in the form of droplets, the cleaning effect of the cleaning object using the liquid is improved compared to a structure in which only a water column is sprayed from the nozzle. Therefore, it is possible to suppress the situation in which the cleaning object is damaged when removing attached matter from the cleaning object, and to effectively remove attached matter from the cleaning object.

[0044] Example 1

[0045] The cleaning device 1 of the present invention sprays liquid 3 in a continuous flow 3a and converts the continuous flow 3a into droplets 3b, and makes the liquid 3 collide with the cleaning object 4 in the form of droplets 3b, thereby removing the attached matter 4b from the target object 4a of the cleaning object 4. Figure 1 An overview of a cleaning tool 1A according to Embodiment 1 will be described as an example of the cleaning tool 1 of the present invention.

[0046] Figure 1The cleaning tool 1A of the embodiment shown has a main body 12 and a nozzle 11, and the nozzle 11 is installed in the main body 12, and sprays the liquid 3 in a continuous flow 3a and converts the continuous flow 3a into droplets 3b. In addition, the cleaning tool 1A of the embodiment has: a liquid tank 23, which stores the liquid 3 sprayed from the nozzle 11; a liquid flow path 13, a part of which passes through the inside of the main body 12 and connects the liquid tank 23 and the nozzle 11; and a pump 21, which supplies the liquid 3 from the liquid tank 23 to the nozzle 11.

[0047] Here, the pump 21 is provided with a switch 21A for turning the pump 21 on or off. The switch 21A can be turned on or off manually by the user. In addition, the cleaning device 1A of this embodiment comprises: a spray pressure adjustment unit 22 for adjusting the spray pressure of the liquid 3 from the nozzle 11; and a control unit 24 for being connected to the spray pressure adjustment unit 22 and controlling the drive of the pump 21. As an example of the control unit 24, a CPU, an ASIC, an FPGA, etc. can be listed. A storage unit 25 is provided in the control unit 24, and the storage unit 25 stores various data, a driver program of the pump 21, etc. As an example of the storage unit 25, a volatile memory such as DRAM (Dynamic random access memory), a non-volatile memory such as ROM (Read-only memory), and a flash memory can be listed.

[0048] Thus, the cleaning device 1A of the present embodiment becomes a structure that can turn on or off the injection of the liquid 3 by the switch 21A. However, it is not limited to such a structure, for example, it can be set to be able to control the strength of the injection pressure of the liquid 3 by the switch 21A. As the switch 21A, it can be set as a foot switch that the user can operate with his foot, or it can be set as a hand switch formed on the main body 12 in a manner that the user can operate by hand while holding the main body 12. On the other hand, it can also be set to be able to change the strength of the injection pressure of the liquid 3 according to the attachment 4b. The cleaning device 1A of the present embodiment can turn on or off the pump 21 at an appropriate time by the switch 21A, so that the amount of liquid 3 used can be appropriately controlled, and the removal performance of the attachment 4b per the amount of liquid 3 used can be improved.

[0049] The cleaning device 1A of the present embodiment has such a structure that the three-dimensional modeling machine supports and models the three-dimensional modeling object using the supporting material, and the cleaning device 1A removes the supporting material as the attached matter 4b from the three-dimensional modeling object 4 formed by the three-dimensional modeling machine by ejecting the liquid 3 from the nozzle 11 and causing the liquid 3 to collide with the cleaning object 4 in the form of droplets, thereby removing the supporting material as the attached matter 4b from the three-dimensional modeling object as the target object 4a in the cleaning object 4. In this way, the liquid 3 is ejected from the nozzle 11 in the form of a continuous flow 3a and the continuous flow 3a is converted into droplets 3b, so that the liquid 3 collides with the cleaning object 4 in the form of droplets 3b, thereby improving the cleaning effect of the liquid 3 on the cleaning object 4 compared with the structure in which only water column water is ejected from the nozzle 11 and the liquid 3 is collided with the cleaning object 4 in the form of a continuous flow based on stagnation pressure. Therefore, the cleaning device 1A of the present embodiment can remove the supporting material from the three-dimensional modeling object while suppressing the damage of the three-dimensional modeling object when removing the supporting material from the three-dimensional modeling object. Furthermore, the supporting material can be removed from the three-dimensional object in a shorter time than when the user removes the supporting material from the three-dimensional object manually using a tool or the like, for example.

[0050] Here, in the cleaning device 1A of the present embodiment, the liquid 3 is stored in the liquid tank 23 connected to the pump 21. However, it is not limited to such a structure. For example, regarding the supply of the liquid 3 to the pump 11, it is also possible to directly supply the tap water as the liquid 3 from the tap of the tap water to the pump 11 by connecting a pipe to the tap of the tap water, etc. Moreover, instead of connecting the liquid flow path 13 to the pump 21, the liquid flow path 13 can be directly connected to the tap of the tap water. In addition, the type of liquid 3 is not particularly limited. In addition to water such as tap water, it can also be a liquid 3 mixed with abrasive powder, etc. However, in the case of mixing abrasive powder, these abrasive powders preferably use abrasive powders with a particle size smaller than the inner diameter of the nozzle 11. This is to prevent the abrasive powder from clogging the nozzle 11. Furthermore, it can also be a liquid 3 mixed with chemicals, etc. As miscible chemicals, for example, acetone, isopropyl alcohol, sodium hydroxide, etc. can be listed.

[0051] In addition, the cleaning device 1A of the present embodiment is configured to be able to remove supporting materials attached to three-dimensional objects formed by three-dimensional modeling machines of various structures. In other words, the cleaning device 1A of the present embodiment can use multiple types of supporting materials. Moreover, as described above, the cleaning device 1A of the present embodiment includes a storage unit 25 and a spray pressure adjustment unit 22. The storage unit 25 stores a correspondence between the type of supporting material and the spray pressure of the liquid 3, and the spray pressure adjustment unit 22 can adjust the spray pressure of the liquid 3 from the nozzle 11 according to the type of supporting material based on the correspondence, through the control of the control unit 24. Therefore, the cleaning device 1A of the present embodiment can automatically and appropriately adjust the spray pressure of the liquid 3 from the nozzle 11 according to the type of supporting material, and effectively remove the supporting material from the three-dimensional object. It should be noted that the correspondence is set to a spray pressure that can remove the supporting material without damaging the three-dimensional object.

[0052] In addition, the cleaning device 1A of the present embodiment is capable of replacing the nozzle 11 mounted on the main body 12. Moreover, by replacing the nozzle 11, the nozzle diameter of the injection port from which the liquid 3 is ejected from the nozzle 11 can be changed. Therefore, the cleaning device 1A of the present embodiment can eject the liquid 3 from the nozzle 11 of a preferred nozzle diameter, for example, depending on the type of supporting material, etc. It should be noted that, in the present embodiment, it is configured so that, by replacing the nozzle 11 mounted on the main body 12, the liquid 3 can be ejected from the nozzle 11 of a preferred nozzle diameter, for example, depending on the type of supporting material, etc. However, the present invention is not limited to such a structure, and it is also possible to install a nozzle 11 having a plurality of injection ports with different nozzle diameters on the main body 12, and to appropriately change the structure of the injection port used in the nozzle 11.

[0053] As described above, the cleaning device 1A of this embodiment can change the spray pressure, nozzle diameter, etc. as the removal conditions according to the conditions of the attached matter 4b to be removed. In addition, it is equipped with a temperature adjustment mechanism (heater) not shown in the figure, which can adjust the temperature of the liquid 3 sprayed from the nozzle 11. Therefore, it can be configured to prompt the user with the spray pressure of the liquid 3, the nozzle diameter, the type of the liquid 3, the temperature of the liquid 3 based on the temperature adjustment mechanism not shown, etc., or automatically change the setting according to the conditions such as the material, thickness, density, shape, etc. of the three-dimensional object and the supporting material.

[0054] Here, the cleaning tool 1A of this embodiment can automatically change the spraying condition of the liquid 3 from the nozzle 11 by inputting the material type of the supporting material from the user, referring to the corresponding relationship stored in the storage unit 25, that is, the spraying condition table, and can make the display unit (not shown) etc. indicate the preferred spraying condition. Figure 2 The flowchart below illustrates an example. Figure 2As shown, first, in step S110, the user inputs the material type of the supporting material via an input unit (not shown). Next, in step S120, the cleaning tool 1A of this embodiment reads the corresponding relationship stored in the storage unit 25, that is, the spray condition table. Then, finally, in step S130, the cleaning tool 1A of this embodiment is set to the spray condition automatically selected according to the material type of the supporting material used, or the spray condition selected by the user via an input unit (not shown).

[0055] In addition, the cleaning device 1A of this embodiment is as follows Figure 1 As shown, a tray, that is, a storage portion 31, is provided that can store the liquid 3 ejected from the nozzle 11. Therefore, the cleaning tool 1A of this embodiment can efficiently recover the liquid 3 ejected from the nozzle 11 and the removed supporting material. Furthermore, the cleaning time accompanied by the liquid 3 and the removed supporting material flying around can be shortened.

[0056] It should be noted that the cleaning device 1A of this embodiment is as follows Figure 1 As shown, the main body 12 is provided with a handpiece type for manual operation. Therefore, the cleaning object 4 can be fixed, and the configuration and posture of the nozzle 11 can be changed relative to the fixed cleaning object 4. However, it is not limited to such a structure, and it can also be set as a structure that changes the configuration and posture of the cleaning object 4 relative to the fixed nozzle 11. In addition, it can also be set as a component such as the nozzle 11 is replaced or additional components are added according to the type of the cleaning object 4. In addition, it can also be that with the replacement or addition of components, the injection state of the liquid 3 can be switched by a switch 21A or the like. In addition, the cleaning tool 1A of this embodiment can use a nozzle 11 with a jet port having one hole, and can also use a nozzle 11 with a jet port having multiple holes. By using a nozzle 11 with a jet port having multiple holes, the droplets 3b can be effectively collided with the wide surface of the cleaning object 4.

[0057] In other words, the cleaning tool 1A of the present embodiment includes a main body 12 connected to the nozzle 11, and a liquid flow path 13 passes through the inside of the main body 12 as a flow path for the liquid 3 to flow. That is, the cleaning tool 1A of the present embodiment includes a main body 12 connected to the nozzle 11 and having a flow path for the liquid 3 to flow inside. The cleaning tool 1A of the present embodiment has such a structure, so that the user can hold the main body 12 and easily make the liquid drop 3b collide with the preferred location of the cleaning object 4.

[0058] Example 2

[0059] Below, refer to Figure 3 The cleaning tool 1B according to the second embodiment will be described. Figure 3 The cleaning device 1A of the first embodiment Figure 1The cleaning device 1B of this embodiment is the same as the cleaning device 1A of the first embodiment except for the following structure. Therefore, the cleaning device 1B of this embodiment has the same features as the cleaning device 1A of the first embodiment except for the following parts. Figure 3 In the present invention, the same structural components as those in the above-mentioned embodiment 1 are indicated by the same figure marks, and detailed descriptions are omitted.

[0060] like Figure 3 As shown, the cleaning tool 1B of this embodiment includes a housing 32 for using the nozzle 11 inside. The housing 32 is surrounded by a wall portion 33 and a user can insert a hand from the outside into the inside through a hole portion (not shown) formed in the wall portion 33. Therefore, the cleaning tool 1B of this embodiment can suppress the liquid 3 and the removed supporting material from being sprayed to the outside of the cleaning tool 1B. Furthermore, the housing 32 suppresses the liquid 3 and the supporting material from scattering around, improves the user's field of vision when these are scattered, and thus enables the droplets 3b to hit appropriate points, thereby improving the work efficiency.

[0061] In addition, if Figure 3 As shown, the housing 32 of the cleaning tool 1B of this embodiment includes a storage portion 31 for storing the liquid 3 ejected from the nozzle 11. Therefore, the cleaning tool 1B of this embodiment can efficiently recover the liquid 3 ejected from the nozzle 11. It should be noted that, in this embodiment, the storage portion 31 and the housing 32 are integrally formed, but the present invention is not limited to such a structure, and the storage portion 31 and the housing 32 may also be separately formed.

[0062] In addition, if Figure 3 As shown, the cleaning device 1B of this embodiment has a circulation mechanism, which has a circulation pipe 34, a pump 27, and a filter 26, and the circulation pipe 34 is connected to the storage portion 31 and the liquid tank 23. The pump 27 is configured to be able to deliver the liquid 3 stored in the storage portion 31 to the liquid tank 23 via the circulation pipe 34. In other words, the cleaning device 1B of this embodiment has a circulation mechanism (circulation pipe 34) for spraying the liquid 3 stored in the storage portion 31 from the nozzle 11 again. Therefore, the cleaning device 1B of this embodiment can reuse the liquid 3 sprayed once from the nozzle 11 and recovered. By reusing the sprayed and recovered liquid 3, the amount of liquid 3 used can be reduced.

[0063] It should be noted that the storage portion 31 of the cleaning device 1B of the present embodiment is a tray-shaped receiving component capable of receiving the liquid 3. However, the receiving component is not limited to such a structure, and for example, it may be in the shape of a tank, or it may be a water-absorbent component that can be discarded after use or can be reused after drying. In addition, the cleaning device 1B of the present embodiment is provided with a filter 26 as a countermeasure against the mixing of the supporting material as the attachment 4b into the liquid flow path 13. The circulation pipe 34 of the cleaning device 1B of the present embodiment is connected to the storage portion 31 and the liquid tank 23, but is not limited to such a structure. For example, it may also have a recovery tank, and the liquid 3 is recovered after the supporting material contained in the sprayed liquid 3 is filtered by the filter 26. Moreover, it is also possible to replace the recovery tank and be configured to be able to directly discharge the liquid 3 filtered by the supporting material through the filter 26 to a drain tank or the like.

[0064] In addition, if Figure 3 As shown, in the cleaning tool 1B of this embodiment, the housing 32 is provided with a temperature adjustment unit 51, which is a heater capable of adjusting the temperature inside the housing 32. Therefore, the cleaning tool 1B of this embodiment can improve the performance of removing the support material from the three-dimensional object by, for example, increasing the temperature inside the housing 32.

[0065] It should be noted that, in the cleaning device 1B of the present embodiment, the housing 32 is provided with a temperature adjustment unit 51, but the temperature adjustment unit 51 also serves as a heating unit that adjusts the temperature in the housing 32 and ultimately heats the liquid 3 ejected from the nozzle 11. As in the cleaning device 1B of the present embodiment, by providing a heating unit that heats the liquid 3, the performance of removing the supporting material from the three-dimensional object can be improved. It should be noted that the temperature adjustment unit 51 is not limited to being provided in the housing 32, and can be provided adjacent to the liquid flow path 13, or can be provided in the liquid tank 23, etc. That is, the temperature adjustment unit 51 can also have the function of heating the liquid 3 in the liquid tank 23, the pump 21 and the pump 27, the liquid flow path 13, the circulation pipe 34 or the main body 12, or the function of cooling the liquid 3 according to the situation.

[0066] Here, the cleaning device 1B of this embodiment can also use multiple types of supporting materials like the cleaning device 1A of embodiment 1. Moreover, as a temperature control unit, the control unit 24 can control the temperature adjustment unit 51 as a heating unit according to the type of supporting material used. Therefore, the cleaning device 1B of this embodiment can easily remove the supporting material by adjusting the temperature in the housing 32 according to the type of supporting material, thereby improving the performance of removing the supporting material from the three-dimensional object.

[0067] In addition, if Figure 3As shown, the cleaning device 1B of this embodiment is provided with a blower 40 inside the housing 32, and the blower 40 can flow gas through the gas flow path 42 and blow gas from the air supply nozzle 41. The blower 40 can blow away the supporting material remaining on the cleaning object 4, the liquid 3 attached to the inside of the housing 32, the supporting material peeled off from the cleaning object 4, etc. by blowing gas. Moreover, by being able to blow away the liquid film on the collision surface of the droplet 3b that becomes the cause of hindering the impact pressure, the state in which the liquid film hinders the propagation of the impact pressure can be eliminated, and the removal performance of the droplet 3b on the supporting material can be improved. Therefore, by blowing air from the blower 40, the performance of removing the supporting material from the three-dimensional object can be improved.

[0068] In other words, the cleaning device 1B of the present embodiment has a housing 32 for holding a holding portion of a device for removing supporting materials that is different from the nozzle 11. Therefore, the cleaning device 1B of the present embodiment can use a device different from the nozzle 11 for removing supporting materials, thereby improving the performance of removing supporting materials from a three-dimensional object, and eliminating the necessity of separately preparing structural components for holding the device. It should be noted that, as a device different from the nozzle 11 for removing supporting materials, for example, an air dust collector such as a blower 40, a gas suction device, a vibration device, etc. can be listed. In addition, when compressed air is used as the power of the pump 21 or the pump 27, the exhaust gas from the pump 21 or the pump 27 can also be reused as a compressed air source.

[0069] In addition, if Figure 3 As shown, in the cleaning device 1B of this embodiment, the housing 32 is provided with a fan 52, and the fan 52 generates an airflow from the inside to the outside of the housing 32. Therefore, the cleaning device 1B of this embodiment can discharge the mist of the liquid 3 generated inside the housing 32 to the outside of the housing 32. It should be noted that the cleaning device 1B of this embodiment includes the fan 52 for attracting the mist, but it may also include, for example, a charged component for guiding the mist instead of the fan 52.
