Description

Technical Field

[0001] The utility model belongs to the field of hairdressing devices, in particular to a locking prompting device. Background Art

[0002] As is well known, hairdressing appliances allow hair to be straightened and / or made fluffy and wavy. These appliances are usually equipped with a rotating attachment forming a mandrel on which the hair can be shaped or even rolled. The mandrel is usually heated (for example, by hot air) to allow the hair to be fixed in shape. These appliances can blow hot air so that the attachment is heated on the one hand and the hair is heated on the other hand. Existing hairdressing appliances, such as the hairdressing appliance with patent number CN110742382A, are composed of an attachment and a hair dryer, and the locking structure of the attachment and the air outlet of the hair dryer are connected by a protrusion. Since the installation position cannot be directly seen, it is not easy for operators who are not professional in using hairdressing appliances to assemble the two. When the attachment and the hair dryer are installed, the user cannot clearly know from the surface whether they are installed in place. It is easy to cause the attachment to be separated from the hair dryer during use due to the attachment and the hair dryer not being installed properly and not being locked tightly. In addition, if the attachment suddenly separates from the handle during use, the user cannot react in time and turn off the power, and the overall safety factor is low; resulting in a decrease in the user experience.

[0031] like Figure 1-10The utility model is shown as providing a locking prompt device, comprising a handle 1 and an accessory 2, wherein the accessory 2 is provided with a locking piece 3, and the locking piece 3 is provided with a limiting groove 31, the handle 1 comprises an inner shell 11 and an outer shell 12, and a locking device 4 adapted to the locking piece 3 is provided between the inner shell 11 and the outer shell 12, and a locking installation position 13 is provided on the inner shell 11, and the locking device 4 comprises a push button 41, a push block 42 and a reset spring 43, and a limit plate 421 adapted to the limiting groove 31 is provided on the push block 42, one end of the reset spring 43 is pressed against the locking installation position 13, and the other end is pressed against the lower end surface of the push block 42, and the push block 42 is slidably installed in the locking installation position 13, and the push button 41 and the push block 42 are arranged to extend, pass through the outer shell 12, and partially protrude from the surface of the outer shell 12; as shown in FIG. Figure 4 and Figure 5 As shown, the handle 1 is also provided with a prompt device 5, and the prompt device 5 includes a pressure sensor 51, a first circuit board 52, a second circuit board 53 and a prompt light 54. The pressure sensor 51 is arranged below the push block 42 and on one side of the return spring 43. The first circuit board 52 is arranged at the lower end of the pressure sensor 51 and is electrically connected thereto. The first circuit board 52 is electrically connected to the second circuit board 53 through a line, and the second circuit board 53 is electrically connected to the prompt light 54. When the limiting plate 421 does not slide into the limiting groove 31, the push block 42 presses against the return spring 43 and the pressure sensor 51, and then transmits an electrical signal to the prompt light 54 through the pressure sensor 51, and the prompt light 54 lights up. The user who is convenient for operation can intuitively understand that the installation is not successful; when the limiting plate 421 slides into the limiting groove 31, the pushing block 42 releases the reset spring 43 and the pressure sensor 51, and the pressure sensor 51 transmits the electrical signal to the prompt light 54, the prompt light 54 goes out, and the user intuitively understands that the installation is successful; even users who are not professional users of the hairdressing accessory 2 can simply and quickly know from the surface whether it is installed in place, avoiding the problem of the accessory 2 being separated from the hair dryer during use due to the accessory 2 and the hair dryer not being installed and locked well or not being locked tightly, and during use, if the accessory 2 suddenly separates from the handle 1, the prompt light 54 lights up in time to indicate the fault, and the hair dryer cannot be started, thereby improving the safety factor of use after assembly and the user experience.

[0032] Specifically, Figure 3 and Figure 4As shown, sliding protrusions 422 are provided on both sides of the push block 42, and a sliding groove 131 is provided on the locking installation position 13. The sliding protrusion 422 is adapted to the sliding groove 131, and the sliding protrusion 422 is inserted into the sliding groove 131 to limit the position of the push block 42, thereby playing a guiding and limiting role; an extended pressing plate 423 is provided on the push block 42, and a touch pressure switch 511 is provided on the pressure sensor 51, and the touch pressure switch 511 is configured to extend or retract into the pressure sensor 51. When the sliding protrusion 422 slides downward along the sliding groove 131, the extended pressing plate 423 contacts and presses the touch pressure switch 511 downward to retract into the pressure sensor 51, and at the same time, the pressure value is transmitted from the first circuit board 52 and the electrical circuit to the second circuit board 53 through the pressure sensor 51, and the second circuit board 53 receives the pressure value signal and makes a Corresponding control makes the prompt light 54 light up. When the user observes that the prompt light 54 is on, he knows that the accessory 2 is not installed in place on the handle 1, so he keeps adjusting the position until the limit plate 421 slides into the limit groove 31. At this time, the push block 42 is lifted by the return spring 43, and the sliding protrusion 422 slides upward in the sliding groove 131, so that the extended pressing plate 423 moves upward, so that the touch pressure switch 511 is not blocked and extends out from the pressure sensor 51, and transmits the 0 pressure value at this time to the pressure sensor 51, the first circuit board 52 and the second circuit board 53, thereby controlling the prompt light 54 to be powered off and extinguished. When the user observes that the prompt light 54 is off, he knows that the installation is in place. At this time, the hair dryer can be started and work normally. In this way, the hairdressing device combined with the handle 1 and the accessory 2 can be used with peace of mind, thereby improving the user's trust in use.

[0033] More specifically, in addition to being configured to be able to extend or retract into the pressure sensor 51 to measure pressure, the touch-pressure switch 511 can also be configured to extend outside the pressure sensor 51 and have a fixed height, and then the configuration of the extended pressure plate 423 is canceled, that is, the lower end surface of the push block 42 is smooth and has no other structure; when the lower end surface of the push block 42 contacts the touch-pressure switch 511, the contact signal can be transmitted to the prompt light 54, that is, the implementation method of the prompt device 5 is not limited, as long as the required signal value can be correctly transmitted to the prompt light 54 so that the user can obtain accurate information.

[0034] like Figure 3-10As shown, the locking member 3 is provided with a limiting protrusion 32, and the number of the limiting protrusions 32 is multiple and uniformly distributed on the inner circumference of the locking member 3. The limiting protrusions 32 and the limiting grooves 31 are arranged on the locking member 3 so as to correspond to each other inside and outside. The handle 1 is provided with a plurality of first guide grooves 14, second guide grooves 15 and positioning grooves 16 uniformly distributed on the outer wall of the air outlet. Each of the first guide grooves 14, the second guide grooves 15 and the positioning grooves 16 is combined into a group of limiting grooves, and the position of the limiting grooves corresponds to the limiting protrusions 32. During assembly, inside the locking member 3, the limiting protrusions 32 first enter along the first guide grooves 14 and enter the positioning grooves 16 along the second guide grooves 15 by rotating clockwise, so as to limit the limiting protrusions 32 in the upper and lower positions. ; At the same time, on the outer wall of the locking piece 3, the limit plate 421 is aligned with the limit groove 31 and slides into it to lock it, thereby limiting the locking piece 3 in the left and right directions; the entire assembly and alignment process saves time and effort, and the internal and external structures of the locking piece 3 limit the movement in the up, down, left and right directions, so that the accessory 2 and the handle 1 can be more stable and not easy to shake. At this time, the prompt light 54 is off and the installation is in place. At this time, the hair dryer can be started and work normally; when disassembling and replacing the accessory 2, push the push button 41 downward so that the limit plate 421 slides out of the limit groove 31, unlocking the restriction of the locking piece 3 in the left and right directions, and then the accessory 2 is rotated counterclockwise relative to the handle 1 so that the limit protrusion 32 is rotated out of the positioning groove 16, which saves time and effort.

[0035] More specifically, Figure 3 , Figure 6 As shown, a limiting angle 33 is provided on one side of the limiting protrusion 32, a first limiting surface 34 is provided on the limiting angle 33, and a second limiting surface 151 is provided on the second guide groove 15. The first limiting surface 34 and the second limiting surface 151 are adapted to each other. When the limiting protrusion 32 is pushed into the positioning groove 16, the first limiting surface 34 and the second limiting surface 151 are abutted against each other, thereby preventing the limiting protrusion 32 from detaching from the positioning groove 16 during use, thereby improving stability.

[0036] In general, when the handle 1 and multiple different types of accessories 2 are combined one by one, the accessories 2 can be quickly replaced to facilitate users to achieve multiple uses of one machine. When replacing and using the accessories 2, the user can simply and quickly know from the surface whether the handle 1 and the accessories 2 are installed in place through the lighting or extinguishing of the prompt light 54. At the same time, the product can be set not to be started or can be started normally according to whether the accessories are effectively installed, thereby improving the safety factor of use after assembly and the user experience.
