Description

Technical Field

[0001] This invention relates to a suction-type electric hair clipper and a suction-type electric hair clipper device. Background Technology

[0002] In recent years, with the progress of an aging society, the number of people spending most of their day in a supine position in hospitals, nursing homes, and at home is increasing. For these so-called "bedridden" individuals, it is often difficult to keep their bodies upright in bed. For some, even a slight lift can be challenging.

[0003] Typically, when cutting hair for someone lying on their back in bed, the beautician or barber (hereinafter referred to as "the barber") usually ensures sufficient space between the bed and the customer's head by supporting the customer's head while cutting their hair. With the customer lying on their back, the height of the back of their head relative to the top surface of the bed is usually no more than 15-20 cm. Considering the significant strain this would place on the customer, it is not preferable to raise their head above this height.

[0004] Furthermore, in hospitals or nursing homes, some customers may suffer from dementia or mental illness. In such cases, for the safety of the customer, the hairdresser will use a suction-type electric hair clipper instead of the scissors used in beauty salons and barbershops.

[0005] The suction-type electric hair clipper can be connected to a household vacuum cleaner by attaching an included suction cap to the main body of the electric hair clipper. The hairdresser uses the electric hair clipper to trim the customer's hair while simultaneously vacuuming, and the trimmed hair is collected inside the vacuum cleaner. The applicant has invented the suction-type electric hair clipper shown in Patent Documents 1 and 2.

[0006] Since both Patent Document 1 and Patent Document 2 describe suction-type electric hair clippers with a built-in power supply, the main body of the hair clipper is relatively large due to this built-in power supply. When the structure is large, the operability of the suction-type electric hair clipper is poor; therefore, an improvement is sought.

[0022] Embodiments of a suction-type electric hair clipper and a suction-type electric hair clipper device will now be described with reference to the accompanying drawings. Furthermore, the same reference numerals are used for the same components in the drawings. Additionally, for ease of explanation, the dimensions in the drawings have been exaggerated and may differ from actual proportions.

[0023] Example 1

[0024] Figure 1 This is a side view showing the overall structure of the suction-type electric hair clipper according to the embodiment. The suction-type electric hair clipper 100 is a handheld device that is gently held in one hand to trim (cut) a customer's hair. Figure 1 As shown, the main body of the suction-type electric hair clipper 100 is composed of an upper housing (first housing) 110, a middle housing 120, and a lower housing (second housing) 130. The upper housing 110, the middle housing 120, and the lower housing 130 are made of plastic. The main body of the hair clipper is integrally formed by attaching the middle housing 120 to the lower housing 130 and attaching the upper housing 110 to the middle housing 120.

[0025] The hair clipper blade 140 is detachably mounted at one end of the lower housing 130. A space 150 is formed between the blade portion 140a of the hair clipper blade 140 and one end 110a of the upper housing 110. The space 150 serves as a hair suction port.

[0026] exist Figure 1As shown in the side view, the suction width h between the blade portion 140a and the end portion 110a forming the space 150 is approximately equal to the length R of the blade portion 140a in the depth direction. The depth of the space 150 is longer than the blade portion 140a of the hair clipper blade portion 140, and also includes the length of the end portion 110a of the upper housing 110 in the lateral direction. Furthermore, as... Figure 3 and Figure 4 As shown, the lateral width of the space portion 150 has the length in the longitudinal direction of the end portion 110a of the upper housing 110 (the blade width of the blade portion 140a).

[0027] like Figure 3 and Figure 4 As shown, the end 110a of the upper housing 110 is a suction port for drawing hair through the space 150. During trimming, the customer's hair is drawn from the space 150, and the drawn hair is cut by the blade 140a of the clipper blade 140. The cut hair passes through the suction channel 160 formed between the upper housing 110 and the intermediate housing 120 (see...). Figure 2 The hair is drawn into the suction hose 200, which will be described later. Therefore, according to the suction-type electric hair clipper 100, the cut hair does not scatter around, but is drawn into a vacuum cleaner (not shown) via the suction hose 200.

[0028] The blade portion 140a of the hair clipper blade section 140 includes a movable blade and a fixed blade (neither shown) formed in a comb-like shape in the vertical direction. Hair drawn into the end portion 110a of the upper housing 110 via the space portion 150 is supported by the fixed blade. The movable blade reciprocates in the horizontal direction while in contact with the fixed blade. Accordingly, the hair is clamped and cut by the edges of the blades of the movable blade and the fixed blade.

[0029] Figure 2 This is a diagram showing the suction-type electric hair clipper 100 as viewed from the rear, and a diagram showing the suction-type electric hair clipper assembly connected to the suction hose of the suction-type electric hair clipper 100. Between the upper housing 110 and the middle housing 120, a [structure / structure] is formed... Figure 1 The space 150 is connected to the suction channel 160. The end of the suction channel 160 is formed into a connection opening 170. A pair of power terminals (power connection portions) 180 are provided inside the connection opening 170 of the suction channel 160. In addition, a tilting member 190 is provided in front of the power terminals 180 inside the connection opening 170 (in the opposite direction to the suction direction). The tilting member 190 is used to suck the hair upward to the wall side so that the cut hair will not get tangled with the power terminals 180.

[0030] Figure 2The right side shows a suction hose 200 connected to the connection opening 170. One end of the suction hose 200 is connected to a vacuum cleaner (not shown), and the other end is provided with a hose cap 210. In addition, a power connector 230 is provided on the suction hose 200, which is arranged side by side with the hose cap 210 and is connected to an external power cord 220.

[0031] The hose cap 210, which is installed at the other end of the suction hose 200, is held in place by a first hose connection cap 550 and an opposing second hose connection cap 560 so as not to detach from the suction hose 200. Plunger mounting portions (not shown) are provided on both sides of the hose cap 210, in which plungers 580 are pressed.

[0032] The hose cap 210 of the suction hose 200 and the power connector 230 are inserted into the connection opening 170 and engaged internally by the plunger 580. When the power connector 230 is inserted into the connection opening 170, it is connected to a pair of power terminals 180. The suction-type electric hair clipper 100 of this embodiment does not have a built-in power supply. Therefore, the external power cord 220 is connected to the substrate 440 described later (see [link to documentation]) via the power connector 230 and the pair of power terminals 180. Figure 7 Thus, the suction-type electric hair clipper 100 does not have a built-in power supply, and therefore has a compact shape.

[0033] Additionally, the power supply structure can be modified as appropriate. For example, the power cord 220 can be routed inside the suction hose 200 (e.g., along the wire inside the hose) instead of being attached to the outside. Alternatively, it can be configured such that the power connector (recessed side) is mounted inside the connection opening 170, and a pair of power terminals (convex side) are mounted to the suction hose 200 side.

[0034] A power switch 195 is provided on the rear side of the suction-type electric hair clipper 100. The power switch 195 is operated by the user (e.g., a hairdresser). The power switch 195 controls the ON / OFF operation of the motor 400 (described later) and the LED lighting unit 460. The user can operate the ON / OFF operation using a finger (e.g., index finger) that holds the main body of the hair clipper. The power switch 195 is, for example, a slide switch.

[0035] Figure 3 and Figure 4 An enlarged perspective view is shown around the clipper blade 140 and the end 110a of the upper housing 110 of the suction-type electric hair clipper 100. Figure 3 and Figure 4As shown, a concave inlet opening 250 is formed at the end 110a of the upper housing 110. Furthermore, a lens cover 260 is installed in the inlet opening 250 in a direction away from the blade portion 140a. The LED cover 270, described later, is installed in the intermediate housing 120 at a position opposite to the lens cover 260. An LED 470 (see [link to LED cover 270]) is located below the LED cover 270. Figure 7 The light passes through the LED cover 270 and the lens cover 260 and shines around the blade 140a. Therefore, since the area around the blade 140a can be brightly illuminated during haircutting, the trimming work can be carried out while observing the condition of longer hair.

[0036] Figure 5 A front view of the suction-type electric hair clipper 100, as seen from the lower housing 130 with the clipper blade 140 removed, is shown. An eccentric rotating shaft 280 is located on the portion where the clipper blade 140 has been removed. The eccentric rotating shaft 280 is connected to the rotating shaft of the motor 400, described later. This means that the eccentric rotating shaft 280 is not located on the rotating shaft of the motor 400, but rather at a position offset from the (eccentric) shaft. Accordingly, the rotational movement of the eccentric rotating shaft 280 has a range of motion. This range of motion is transmitted to the clipper blade 140 and converted into a reciprocating motion of the movable blade in the horizontal direction. As a result, the movable blade of the blade section 140a moves left and right at high speed to cut hair. Two leaf springs 290 are provided on both sides of the eccentric rotating shaft 280. The leaf springs 290 are capable of suppressing vibration of the clipper blade 140. Figure 5 As shown, the main body of the hair clipper has a constricted neck shape in the center, making it easy to hold with one hand.

[0037] Figure 6 This shows the upper housing 110 being removed from... Figure 1 The upper surface of the intermediate housing 120 when the suction-type electric hair clipper 100 is removed (perspective view). Figure 6 As shown, Figure 3 The LED cover 270 shown is disposed on the inclined portion 300 of the intermediate housing 120 located on the side of the hair clipper blade 140. Additionally, Figure 2 The tilted member 190 and the pair of power terminals 180 shown are formed to protrude from the upper surface of the intermediate housing 120. Furthermore, as... Figure 6 As shown, the width of the suction channel 160 on the inner surface of the upper housing 110 is formed to narrow in the suction direction starting from the inlet opening 250. Accordingly, the trimmed hair can be drawn into the suction hose 200 through the suction channel 160 without scattering.

[0038] Figure 7 Showing from Figure 6The upper surface of the lower housing 130 of the suction-type electric hair clipper 100 when the intermediate housing 120 is further removed (perspective view). The motor 400 is located in the central portion of the lower housing 130. A first buffer member (made of rubber) 410 and a second buffer member (made of rubber) 420 are located on either side of the motor 400. Figure 7 The flat ends (left and right sides) of the motor 400 are housed within the mounting ribs of the lower housing 130. The first buffer component 410 and the second buffer component 420 absorb vibrations accompanying the rotation of the motor 400 and suppress noise generation. The eccentric rotating shaft 280 of the motor 400 is supported by ball bearings 430. The ball bearings 430 are housed within the mounting ribs of the lower housing 130. The ball bearings 430 smoothly guide the rotation of the eccentric rotating shaft 280.

[0039] The substrate 440 is disposed at the rear end of the lower housing 130, between the motor 400 and the power switch 195. Three connectors are provided on the substrate 440: a first connector for connection to the power terminal 180, a second connector for connection to the motor 400, and a third connector for connection to the LED substrate 480. Foam tape 450 is disposed at the ends of both sides of the substrate 440. When the lower housing 130 and the middle housing 120 are joined, the foam tape 450 functions as a buffer between the upper and lower housings.

[0040] An LED lighting unit 460 is disposed on one side of the hair clipper blade section 140 of the lower housing 130. The LED lighting unit 460 comprises an LED substrate 480 on which LEDs 470 are mounted and an LED cover 270 covering the upper surface of the LEDs 470. The LED substrate 480 is fixed to the lower housing 130 by screws. Furthermore, Figure 2 The two leaf springs 290 shown are fixed to the lower housing 130 by fastening screws 490 on both sides.

[0041] Figure 8 This diagram shows the wiring of the substrate 440 located behind the motor 400 in the lower housing 130 (viewed from the inside of the lower housing 130). The substrate 440 is equipped with a power connector (first connector) 500 connected to the power terminal 180, a motor connector (second connector) 520 connected to the motor 400 via wiring 510, and an LED connector (third connector) 540 connected to the LED substrate 480 via wiring 530.

[0042] When trimming hair using a suction-type electric hair clipper with the above-described structure, the hair is trimmed short by pointing the blade 140a toward the hair and moving the suction-type electric hair clipper 100 from bottom to top or from top to bottom.

[0043] As described above, according to the embodiment, it is possible to construct a compact structure without a built-in power supply unit, cutting and sucking hair into the space formed in the main body. Furthermore, it is possible to provide a suction-type electric hair clipper and a suction-type electric hair clipper device with new functions such as suction function, noise reduction function, and lighting function.

[0044] The suction-type electric hair clipper described in this embodiment has a hair clipper body consisting of a first housing (upper housing) 110, a second housing (lower housing) 130, an intermediate housing 120 located between the first housing 110 and the second housing 130, a hair clipper blade 140 mounted at one end of the second housing 130, a motor 400 provided in the second housing 130 and driving the hair clipper blade 140, a suction channel 160 formed by the connection of the first housing 110 and the intermediate housing 120, a power connection portion 180 provided in the suction channel 160, and a connection opening 170 formed at the other end of the first housing 110 and into which a power cord 220 connected to the power connection portion 180 is inserted. Therefore, it is possible to provide a compact and easy-to-operate hair clipper body without a built-in power supply.

[0045] Furthermore, in this embodiment, the suction-type electric hair clipper forms a space 150 between the blade 140a of the clipper blade section 140 and one end 110a of the first housing 110. Since the suction gap width h of the space 150 is equal to the length R in the depth direction of the blade 140a, the hair sucked into the space 150 can be cut by the blade 140a. Because the cut hair is sucked into the suction hose 200 connected to a vacuum cleaner (not shown) via the suction channel 160, the cut hair does not scatter. Therefore, there is no need to clean up the cut hair.

[0046] Furthermore, in this embodiment, the depth of the space portion 150 of the suction-type electric hair clipper is longer than the length R of the blade 140a in the depth direction, and is also the length in the lateral direction of one end portion 110a of the first housing 110. Since the width of the space portion 150 is the longitudinal length of one end portion 110a of the first housing 110, a space portion 150 most suitable for haircutting is formed. Therefore, hair sucked into the space portion 150 can be cut by the blade 140a.

[0047] Furthermore, the rotating shaft 280 of the motor 400 of the suction-type electric hair clipper is supported by a ball bearing 430, and buffer components 410 and 420 are respectively installed on the flat ends of both sides of the motor 400, thus allowing the rotating shaft 280 to rotate smoothly via the ball bearing 430. Additionally, the buffer components 410 and 420 reduce vibrations associated with the rotation of the motor 400. As a result, the leakage of motor 400 noise to the outside is reduced.

[0048] Furthermore, in this embodiment, one end 110a of the first housing 110 of the suction-type electric hair clipper has a concave shape, and a translucent lens cover 270 is provided in the concave portion. An LED lighting section 460 is provided in the second housing 130 opposite to the lens cover 270, thus brightly illuminating the area around the blade 140a of the hair clipper blade section 140. As a result, operability during haircuts is improved.

[0049] Furthermore, the suction-type electric hair clipper of this embodiment also includes a base plate 440 disposed at the other end of the second housing 130, a first connector (power connector) 510 mounted on the base plate 440 and connected to the power connection portion 180, a second connector (motor connector) 520 connected to the motor 400, and a third connector (LED connector) 530 connected to the LED lighting portion 460. Therefore, power can be supplied from the outside to the motor 400 and the LED lighting portion 460 via the power connection portion 180 and the base plate 440. As a result, the main body of the suction-type electric hair clipper can be compactly formed.

[0050] In addition, because the tilting member 190 is formed in front of the power connection part (power terminal) 180 of the suction channel 160, the cut hair is drawn from the upper wall side of the first housing 110 into the suction hose 200, so there is no need to worry about the hair getting tangled with the power connection part 180, and the safety is excellent.

[0051] The suction-type electric hair clipper device involved in the embodiment has a hair clipper body consisting of a first housing 110, a second housing 130, an intermediate housing 120 located between the first housing 110 and the second housing 130, a hair clipper blade 140 mounted at one end of the second housing 130, a motor 400 provided in the second housing 130 and driving the hair clipper blade 140, a suction channel 160 formed by the connection of the first housing 110 and the intermediate housing 120, a power connection portion 180 provided in the suction channel 160, a connection opening 170 formed at the other end of the first housing 110, and a suction hose 200 with one end connected to a vacuum cleaner (not shown), the other end inserted into the connection opening 170, and a power cord 220 connected to the power connection portion 180. Therefore, it can provide a hair clipper body that is compact in shape and easy to operate without a built-in power supply.

[0052] Furthermore, the power connection portion 180 of the suction-type electric hair clipper device in this embodiment consists of a pair of power terminals. The other end of the suction hose 200 has a hose cap 210 and a power connector 230 for connecting the power cord 220. When the hose cap 210 and the power connector 230 are inserted into the connection opening 170, the power connector 230 connects to the pair of power terminals 180. Therefore, power supplied from the external power cord 220 can be connected to the internal substrate 440 via the power connection portion 180. As a result, power can be supplied to the motor 400 and the LED lighting unit 460 via the power connection portion 180 and the substrate 440. Accordingly, the main body of the suction-type electric hair clipper can be compactly formed.

[0053] The embodiments of the present invention are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. Furthermore, these embodiments and their variations are included within the scope and spirit of the invention, and are included within the scope of the invention as described in the claims and their equivalents.
