Description

Technical Field

[0001] The invention relates to the technical field of ironing equipment, and in particular to an ironing equipment with a detachable power supply. Background Art

[0002] Conventional ironing equipment products, such as electric irons, are relatively large in size and weight, inconvenient to use and carry, and must be powered by a power cord to be used, which cannot meet consumers' wireless needs. In addition, the handle of existing electric irons is usually fixedly connected to its heating structure and cannot be disassembled, making it difficult to carry and store. At the same time, the handle is usually connected to a power cord and needs to be plugged in before use, which limits the distance and occasions of use.

[0003] In order to solve the above technical problems, the Chinese invention patent with application number CN201910512683.1 (publication number: CN110130082A) discloses "A new type of wireless ironing device", including a heating structure with a water drop shape on the lower surface and a strip-shaped handle, the heating structure and the handle are detachably connected through a magnetic structure, wherein a lithium battery is provided in the handle, and a ceramic heating sheet is provided in the heating structure; the magnetic structure includes: a magnet and an iron sheet, the magnet matches the iron sheet, the magnet is arranged in the heating structure and the iron sheet is arranged in the handle, or the magnet is arranged in the handle and the iron sheet is arranged in the heating structure; the magnetic structure also includes: a first contact and a second contact, the first contact matches the second contact, the first contact is electrically connected to the ceramic heating sheet, the second contact is electrically connected to the lithium battery, and the first contact and the second contact are detachably electrically connected. The wireless ironing device in this patent is light in weight, easy to carry, and requires little storage space, and can meet the wireless needs of electric irons.

[0004] However, in actual use, the wireless ironing device in the above patent still has certain shortcomings. First, the device body (heating structure) and the handle are connected by a magnetic suction structure, which mainly relies on the suction of the magnet to fix the two. Due to the limitation of the suction of the magnet itself, the fixation between the two is not very reliable, and there will be shaking and loosening, which will lead to unreliable connection between the conductive contacts between the two, affecting the stability and safety of the entire product. Secondly, although the above wireless ironing device can achieve the purpose of convenient collection by detaching the handle from the device body, there is a problem that the handle is easy to lose when the two are completely separated. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an ironing device with a detachable power supply, which can realize a reliable connection between a handle and a device body and thereby improve the power supply stability, in view of the current status of the prior art.

[0006] The technical solution adopted by the present invention to solve the above technical problem is: an ironing device with a detachable power supply, comprising:

[0007] A device body, on which a first power terminal is provided;

[0008] A handle, detachably connected to the device body, comprising a handle body and a power supply module assembled on the handle body, wherein the handle body is also provided with a second power terminal electrically connected to the power supply module;

[0009] A locking assembly, acting on the handle that has been connected to the device body, so that the handle is locked relative to the device body;

[0010] The handle is constrained on the device body in a relatively movable manner, and when the locking assembly locks the handle, the second power terminal of the handle is electrically connected to the first power terminal of the device body.

[0011] In order to connect the handle and the device body and enable relative movement between the two, the device body is provided with a boss protruding outward from the outer wall surface of the device body, and the handle is provided with a storage groove for receiving the boss. The boss of the device body is constrained in the storage groove in a relative sliding or relative rotation manner, the first power terminal is arranged at the top of the boss, and the second power terminal is arranged at the bottom of the storage groove.

[0012] As a preferred embodiment, the handle storage groove is a strip storage groove extending along the length direction of the handle, and the boss is a square boss. The two opposite side walls of the square boss are provided with laterally extending strip slide grooves, and the edges of the two opposite side walls of the strip storage groove have strip clamping ribs protruding toward the middle, and the two strip clamping ribs correspond to the sliding limits located in the two strip slide grooves of the square boss.

[0013] As another preferred embodiment, the boss is a cylindrical boss, and the receiving groove is an arc-shaped receiving groove arranged on the outer wall of the handle. The peripheral wall of the cylindrical boss has a radially concave annular groove, and the edge of the arc-shaped receiving groove has an arc-shaped retaining rib protruding radially inward. The sliding limit of the arc-shaped retaining rib is located in the annular groove of the cylindrical boss, so that the handle can rotate around the axis of the cylindrical boss.

[0014] In order to better adapt the rotational matching structure or sliding matching structure between the receiving groove of the handle and the boss of the device body, and realize automatic locking between the two during the rotation or sliding process of the handle relative to the device body, the locking assembly includes:

[0015] The locking member is in the shape of a rod and is movably arranged on the top of the boss of the device body along its own axial direction, and the outer end of the locking member passes through the top surface of the boss of the device body and is inserted into a corresponding recessed portion on the bottom surface of the receiving groove of the handle to achieve locking cooperation between the handle and the device body;

[0016] The elastic member acts on the locking member and makes the outer end of the locking member always have a tendency to be exposed from the top surface of the boss.

[0017] In order to facilitate the placement of the elastic member and improve the stability of the axial movement of the locking member, the boss of the device body has a placement groove for placing the elastic member and a limiting hole that passes from the top surface of the boss to the placement groove. The locking member is inserted into the limiting hole and is limited on the peripheral edge of the inner port of the limiting hole by a blocking portion that protrudes radially outward on the peripheral wall of the inner end of the locking member.

[0018] The elastic member can be selected from elastic elements such as springs, spring sheets, torsion springs, etc. in the prior art. In order to better cooperate with the locking member structure, the elastic member is mainly a spring and is pressed between the inner end of the locking member and the wall of the placement groove.

[0019] In order to enable the locking member to automatically retract along its axial direction when being touched by the handle during the rotation of the handle, the outer end of the locking member is configured to be in a cone shape.

[0020] In order to avoid the problem in the prior art that the handle and the device body can only be separated for storage and reduce the probability of the handle being lost, as a preferred embodiment, the storage groove is a strip storage groove, and two recesses are provided on the bottom surface of the strip storage groove along its length direction, and the locking member can be respectively inserted into the above two recesses, so that the handle is in a first locking position and a second locking position during the sliding process relative to the device body. When the handle is in the first locking position, the handle is unfolded relative to the device body and is in an open state. When the handle is in the second locking position, the handle and the device body are folded together and are in a stored state.

[0021] As another preferred embodiment, the storage groove is an arc-shaped storage groove, and there are at least two recesses on the arc-shaped storage groove, each recess is arranged in a circumferential direction with the axial line of the arc-shaped storage groove as the center, and the locking member can be respectively inserted into the above-mentioned recesses, so that the handle is at least in a first locking position and a second locking position during the rotation relative to the device body. When the handle is in the first locking position, the handle is unfolded relative to the device body and is in an open state, and when the handle is in the second locking position, the handle is folded together with the device body and is in a stored state.

[0022] In order to achieve conductive connection between the second power terminal of the handle and the first power terminal of the device body when the handle is rotated to different angles relative to the device body, the first power terminal of the device body includes an annular conductive sheet located on the top surface of the cylindrical boss and a first conductive contact located at the center of the annular conductive sheet, the annular conductive sheet is coaxially arranged with the cylindrical boss, and the second power terminal of the handle includes a second conductive contact and a third conductive contact, the second conductive contact corresponds to the first conductive contact, and the third conductive contact corresponds to the annular conductive sheet.

[0023] In order to facilitate charging and discharging, the power supply module includes a lithium battery, and the handle body is also provided with a charging interface and a discharging interface electrically connected to the lithium battery. The power supply module adopts a rechargeable lithium battery, and the user can charge the lithium battery separately through the charging interface, so that the lithium battery can power the ironing device, realizing wireless power supply; when the lithium battery is not connected to the ironing device, it can also output low-voltage direct current through the discharging interface to power other devices, and has the function of a mobile power supply.

[0024] Compared with the prior art, the advantages of the present invention are as follows: since the handle of the ironing device is constrained on the device body, the handle will not easily separate from the device body, thereby ensuring the relative stability of the connection between the handle and the device body, and when the handle moves to a set position relative to the device body, the two can be locked by the locking assembly, thereby avoiding slight looseness or shaking between the handle and the device body, achieving reliable power supply between the second power terminal of the handle and the first power terminal of the device body, and improving the stability and safety of the ironing device product.

[0041] The present invention is further described in detail below with reference to the accompanying drawings.

[0042] Example 1

[0043] See also Figure 1-Figure 7 An ironing device with a detachable power supply comprises a device body 10, a handle 20 and a locking assembly 30. The handle 20 is detachably connected to the device body 10. The handle 20 comprises a handle body 21 and a power supply module 22, the power supply module 22 is assembled on the handle body 21, and the handle body 21 is also provided with a second power terminal 23 electrically connected to the power supply module 22. The device body 10 is provided with a first power terminal 11. When the handle 20 is connected to the device body, the second power terminal 23 can be connected to the first power terminal 11 of the device body 10, and the power supply module 22 of the handle 20 can supply power to the device body 10.

[0044] In this embodiment, the handle is constrained on the device body in a sliding manner.

[0045] See also Figure 5 The bottom wall of the handle 20 has a strip-shaped receiving groove 24a extending along its length direction, and the strip-shaped receiving groove 24a is a strip-shaped groove with one end open and the other end closed. Figure 4 The top of the device body 10 has a boss 12a protruding from the outer wall of the device body 10. The boss can be inserted from the opening 26a of the strip storage groove 24a and then correspondingly stored in the strip storage groove 24a. Of course, the boss 12a of the device body 10 can also be removed from the opening 26a of the strip storage groove 24a, so that the two can be separated, so that it is convenient for users to charge the handle 20 or use it as a mobile power source. For details, see Figure 3 .

[0046] Combination Figure 6 and Figure 7, the boss 12a of the device body 10 can be slidably limited in the strip receiving groove 24a. Specifically, the boss of the device body 10 is a square boss 12a extending upward from the top of the device body 10, wherein the two opposite side walls of the boss are provided with a transversely extending strip slide 13a. Correspondingly, the edges of the two opposite side walls of the strip receiving groove 24a are provided with a strip clamp 25a protruding toward the middle, and the two strip clamps 25a can be correspondingly slidably limited in the two strip slides 13a of the boss, that is, the handle 20 and the device body 10 can achieve smooth sliding through the sliding cooperation between the strip clamp 25a and the strip slide 13a.

[0047] See also Figure 4 and Figure 5 The first power terminal 11 of the device body 10 is arranged on the top surface of the boss 12a, and correspondingly, the second power terminal 23 is arranged on the bottom surface of the strip receiving groove 24a. When the handle 20 slides relative to the device body 10, the handle 20 can be in a corresponding locking position. In the locking position, the handle 20 is locked on the device body 10 by the locking assembly 30, and the second power terminal 23 of the handle 20 is electrically connected with the first power terminal 11 of the device body 10.

[0048] See also Figure 3 and Figure 6 The locking assembly 30 is located between the bottom surface of the strip receiving groove 24a of the handle 20 and the top surface of the boss of the device body 10. The locking assembly 30 includes a locking member 31 and an elastic member 32. The locking member 31 is rod-shaped and axially movable on the top of the boss 12a of the device body 10. Specifically, the boss 12a of the device body 10 is hollow inside to form a placement groove 14 for placing the elastic member 32, and a limiting hole 15 is formed on the top wall of the boss 12a, which passes through from the top surface of the boss to the placement groove 14, and the locking member 31 is inserted into the limiting hole 15.

[0049] See also Figure 7 In this embodiment, the elastic member 32 can be a spring. The spring is arranged in the placement groove 14 of the boss of the device body 10. Specifically, the elastic member 32 acts on the inner end of the locking member 31, so that the outer end of the locking member 31 always has a tendency to be exposed from the top surface of the boss. The blocking portion 310 protruding radially outward on the peripheral wall of the inner end of the locking member 31 can be set as an annular convex edge structure. The inner end of the locking member 31 is limited to the peripheral edge of the inner end of the limiting hole 15 by the blocking portion 310, thereby preventing the locking member 31 from slipping out of the limiting hole 15.

[0050] Continue to see Figure 7The inner end face of the locking member 31 has a concave positioning hole 311 , the first end of the spring can extend into the positioning hole 311 and abut against the bottom surface of the positioning hole 311 , and the second end of the spring abuts against the wall surface of the placement groove 14 of the device body 10 .

[0051] Combination Figure 5 The bottom surface of the strip receiving groove 24a of the handle 20 has a concave structure. Under the elastic force of the spring, the outer end of the locking member 31 can be exposed to the top surface of the boss 12a of the device body 10 and correspondingly inserted into the above-mentioned concave portion, thereby realizing the locking cooperation between the handle 20 and the device body 10. In order to make the locking member 31 automatically retract along its axial direction when it is touched by the handle 20 during the lateral sliding process of the handle 20, the outer end of the locking member 31 is in a cone shape.

[0052] See also Figure 5 In this embodiment, the handle 20 can be in the first locking position and the second locking position during the sliding process relative to the device body 10. Correspondingly, the bottom surface of the bar-shaped receiving groove 24a of the handle 20 has two recesses, which are the first recess 271 and the second recess 272. The first recess 271 and the second recess 272 are respectively located at the two end positions of the bar-shaped receiving groove 24a of the handle 20, wherein the second power terminal 23 is arranged adjacent to the first recess 271.

[0053] See also Figure 1 When the outer end of the locking member 31 is inserted into the first recess 271, the handle 20 is in the first locking position. At this time, the second power terminal 23 of the handle 20 is connected to the first power terminal 11 of the device body 10, and the device body 10 can be powered by the power supply module 22 of the handle 20. On the other hand, when the handle 20 is in the first locking position, the handle 20 is unfolded relative to the device body 10 and is in an open state. Specifically, the boss of the device body 10 is arranged near the edge of the device body 10. In this way, when the first end of the handle 20 is connected to the boss of the device body 10, most of the handle 20 (including the second end) can be exposed outside the periphery of the device body 10 for the user to hold.

[0054] See also Figure 2When the outer end of the locking member 31 is inserted into the second recess 272, the handle 20 is in the second locking position. At this time, the second power terminal 23 of the handle 20 is separated from the first power terminal 11 of the device body 10, and the power supply module 22 of the handle 20 no longer supplies power to the device body 10. On the other hand, when the handle 20 is in the second locking position, the handle 20 and the device body 10 are folded together and are in a storage state. Specifically, the boss of the device body 10 is arranged close to the edge of the device body 10, so that when the second end of the handle 20 is connected to the boss of the device body 10, most (or all) of the handle 20 can be overlapped on the top of the device body, which effectively reduces the overall length of the ironing device in the lateral direction, thereby reducing the occupied space and facilitating the user to collect it. Since the handle 20 does not need to be separated from the device body 10, it also avoids the problem of easy loss of the handle 20 caused by the prior art that the handle 20 and the device body 10 can only be separated for collection.

[0055] See also Figure 7 The power supply module 22 of this embodiment includes a lithium battery. The handle body 21 is also provided with a charging interface 28 and a discharge interface 29 electrically connected to the lithium battery. The charging interface 28 of this embodiment is provided on the end wall of the handle body 21, and the discharge interface 29 can be provided on the bottom surface of the strip storage groove 24a. The user can charge the lithium battery separately through the charging interface 28, so that the lithium battery can power the ironing device, realizing wireless power supply. When the lithium battery is not connected to the ironing device, it can also output low-voltage direct current through the discharge interface 29 to power other devices, realizing the mobile power supply function.

[0056] The ironing device with a detachable power supply of this embodiment has the following advantages: since the handle 20 of the ironing device is slidably constrained on the device body 10, the handle 20 will not be easily detached from the device body 10, which can ensure the relative stability of the connection between the handle 20 and the device body 10, and when the handle 20 slides to a set position relative to the device body 10, the locking assembly 30 can lock the two, thereby avoiding slight looseness or shaking between the handle 20 and the device body 10, achieving reliable power supply between the second power terminal 23 of the handle 20 and the first power terminal 11 of the device body 10, and improving the stability and safety of the ironing device product.

[0057] Example 2

[0058] See also Figure 8-Figure 15 , which is different from Example 1, in this embodiment the handle is constrained on the device body in a rotational manner.

[0059] See also Fig.10 and Fig.11The device body 10 has a rotating connection portion, which is a cylindrical boss 12b protruding from the outer wall of the device body 10, and the first end of the handle 20 is rotatably connected to the cylindrical boss 12b of the device body 10. Correspondingly, an arc-shaped receiving groove 24b is formed on the outer wall of the first end of the handle 20 for receiving the top of the cylindrical boss, wherein the cylindrical boss is constrained in the arc-shaped receiving groove 24b and can rotate around the axis of the cylindrical boss 12b.

[0060] See also Fig.10 The cylindrical boss has a radially concave annular groove 13b on its circumferential wall. Figure 4 The arc-shaped receiving groove 24b of the handle 20 is a semi-enclosed arc-shaped groove with its opening 26b facing away from the second end of the handle 20. The edge of the arc-shaped groove has an arc-shaped retaining rib 25b that protrudes toward the middle and can correspond to the sliding limit in the annular groove 13b of the cylindrical boss 12b. When the handle 20 and the device body 10 need to be assembled together, the cylindrical boss 12b of the device body 10 can be installed from the opening 26b of the arc-shaped receiving groove 24b, so that the arc-shaped retaining rib 25b is inserted into the annular groove 13b of the cylindrical boss, wherein the central angle α corresponding to the arc-shaped retaining rib 25b is greater than 180 degrees, so that the cylindrical boss and the arc-shaped retaining rib 25b will not be easily separated, see for details. Figure 7 When the handle 20 and the device body 10 need to be disconnected, the device body 10 can be pushed in the opposite direction to make the cylindrical boss of the device body 10 disengage from the opening 26b of the arc-shaped receiving groove 24b, thereby separating the two, so that the user can charge the handle 20 or use it as a mobile power source. For details, see Fig.15 The cooperation between the arc-shaped clamping rib 25b and the annular sliding groove 13b facilitates the removal and assembly between the handle 20 and the device body 10 and ensures the stability of the relative rotation between the handle 20 and the device body 10.

[0061] See also Fig.10 and Fig.11 In this embodiment, the first power terminal 11 of the device body 10 is arranged on the top surface of the cylindrical boss 12b, and the second power terminal 23 of the handle 20 is arranged on the bottom surface of the arc-shaped receiving groove 24b. When the handle 20 rotates relative to the device body 10, the handle 20 can be in a corresponding locking position. In the locking position, the handle 20 is locked on the device body 10 by the locking assembly 30, and the second power terminal 23 of the handle 20 is electrically connected with the first power terminal 11 of the device body 10.

[0062] See also Fig.12The locking assembly 30 of this embodiment is arranged on a cylindrical boss. The locking assembly 30 and the power supply module 22 of this embodiment have the same structure as the locking assembly and the power supply module in Example 1, and are not described in detail here.

[0063] See also Fig.11 In the present embodiment, there are at least two recesses on the bottom surface of the arc-shaped receiving groove 24b of the handle 20, and the recesses are arranged at intervals in the circumferential direction centered on the axis of the cylindrical boss (that is, in the circumferential direction centered on the axis of the arc-shaped receiving groove 24b).

[0064] See also Fig.11 In this embodiment, there are four recesses, namely, the first recess 271, the second recess 272, the third recess 273 and the fourth recess 274. The first recess 271 and the second recess 272 are symmetrically arranged relative to the axis of the cylindrical boss 12b. Correspondingly, the locking member 31 can be correspondingly inserted into each of the above recesses, so that the handle 20 is in the first locking position, the second locking position, the third locking position and the fourth locking position during the rotation process relative to the device body 10.

[0065] See also Fig. 9 When the outer end of the locking member 31 is inserted into the first recess 271, the handle 20 is in the first locking position. At this time, the second power terminal 23 of the handle 20 is connected to the first power terminal 11 of the device body 10, and the power supply module 22 of the handle 20 can supply power to the device body 10. On the other hand, when the handle 20 is in the first locking position, the handle 20 is unfolded relative to the device body 10 and is in an open state. Specifically, the cylindrical boss 12b of the device body 10 is arranged close to the edge of the device body 10. In this way, when the handle 20 is in the first locking position, most of the handle 20 (including the second end) can be exposed outside the periphery of the device body 10 for the user to hold. In the first locking position, the extension direction of the handle 20 is consistent with the direction of the device body 10 when it is straightened.

[0066] See also Figure 8When the outer end of the locking member 31 is inserted into the second recess 272, the handle 20 is in the second locking position. At this time, the second power terminal 23 of the handle 20 can still be connected to the first power terminal 11 of the device body 10. On the other hand, when the handle 20 is in the second locking position, the handle 20 and the device body 10 are folded together and are in a storage state. Specifically, since the cylindrical boss 12b of the device body 10 is arranged close to the edge of the device body 10, when the handle 20 is rotated and adjusted to be in the second locking position, most (or all) of the handle 20 can be overlapped (such as overlapped in the up and down direction) above the device body 10, which effectively reduces the overall length of the ironing device in the lateral direction, thereby reducing the occupied space and facilitating the user to collect it. Since the handle 20 does not need to be separated from the device body 10, that is, the handle and the device body are always in a restrained state, the problem of the handle 20 being easy to lose caused by the handle 20 and the device body 10 having to be separated for collection in the prior art is also avoided.

[0067] See also Fig.13 When the outer end of the locking member 31 is inserted into the third recess 273 or the fourth recess 274, the handle 20 is correspondingly in the third locking position or the fourth locking position. At this time, the second power terminal 23 of the handle 20 can still be connected to the first power terminal 11 of the device body 10. Similarly, most of the handle 20 (including the second end) can be exposed outside the periphery of the device body 10, and can also be held by the user. Different from the handle 20 being in the first locking position, the extension direction of the handle 20 is inconsistent with the direction of the device body 10 when it is straightened, that is, the handle 20 has a certain tilt angle relative to the device body 10. Of course, it is conceivable that more recesses can be set on the bottom surface of the arc-shaped storage groove 24b of the handle 20, so that the user can rotate the handle 20 to any desired angle according to actual needs.

[0068] See also Fig.10 and Fig.12 In order to ensure that the second power terminal 23 of the handle 20 and the first power terminal 11 of the device body 10 are both connected to each other during the rotation of the handle 20 and the device body 10 at any angle of 360 degrees, the first power terminal 11 of the device body 10 includes an annular conductive sheet 111 located on the top surface of the cylindrical boss and coaxially arranged with the cylindrical boss, and a first conductive contact 112 located at the center of the annular conductive sheet 111. Correspondingly, the second power terminal 23 of the handle 20 includes a second conductive contact 231 and a third conductive contact 232, wherein the second conductive contact 231 corresponds to the first conductive contact 112, and the third conductive contact 232 corresponds to the annular conductive sheet 111.

[0069] The advantages of the wireless power supply ironing device of this embodiment are as follows: the handle 20 of the ironing device is rotatably connected to the rotating connection part of the device body 10, and when the handle 20 is rotated to a set position relative to the device body 10, the locking assembly 30 can lock the handle 20 on the device body 10, thereby avoiding looseness or shaking between the handle 20 and the device body 10, achieving reliable power supply between the second power terminal 23 of the handle 20 and the first power terminal 11 of the device body 10, and improving the stability and safety of the ironing device product.
