[0023] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0024] Next, refer to Figures 1-3 to describe the handle assembly according to an embodiment of the present utility model.

[0025] As Figures 1-3 shown, the handle assembly includes: a handle housing 1 and a fan 2. The fan 2 is disposed in the handle housing 1. The axis of the fan 2 is parallel to the axis of the handle housing 1, and the axis of the fan 2 is offset relative to the axis of the handle housing 1.

[0026] Among them, the handle housing 1 is for the user to hold. The surface of the handle housing 1 is a complete surface, having a good aesthetic effect. In some embodiments, the handle housing 1 can be a plastic shell, which can prevent electric shock and enable light and convenient carrying.

[0027] And, the fan 2 can include a motor and a fan blade. The fan blade is power-coupled to the motor shaft of the motor.

[0028] Exemplarily, the fan 2 can be a centrifugal fan, or the fan 2 can be an axial flow fan.

[0029] By eccentrically disposing the fan 2 in the handle housing 1, a relatively large space can be provided on the side of the fan 2 away from the inner wall of the handle housing 1. This space provides an installation space for arranging functional components such as a power button, making the overall structure compact and having a small volume. It can also make the fan 2 and the inner wall of the handle housing 1 jointly form an air inlet duct with almost no bending, and the air suction is relatively smooth, which is beneficial to improving the air inlet efficiency. In addition, the limited space inside the handle housing 1 can be utilized, and the contact area between the fan 2 and the handle housing 1 or the connecting component for fixing the fan 2 is relatively small, so that the heat dissipation performance of the fan 2 is good to protect stable and reliable operation.

[0030] Further, the inner wall diameter of the handle housing 1 is d1, the outer wall diameter of the blower 2 is d2, and the distance by which the axis of the blower 2 is offset relative to the axis of the handle housing 1 is L. L, d1, and d2 satisfy the relationship: (d1 - d2) / 2 ≥ L > 0.

[0031] It can be understood that the maximum offset distance of the axis of the blower 2 relative to the axis of the handle housing 1 can be such that the outer wall of the blower 2 is closely arranged against the inner wall of the handle housing 1. In this way, the space on the side of the blower 2 away from the inner wall of the handle housing 1 is maximized, which can provide a relatively large installation space for arranging functional components and improve space utilization.

[0032] Further, the distance by which the axis of the blower 2 is offset relative to the axis of the handle housing 1 is L, and L satisfies the relationship: 10 mm ≥ L > 3 mm.

[0033] That is to say, the offset distance range of the axis of the blower 2 relative to the axis of the handle housing 1 cannot be higher than 10 mm and cannot be lower than 3 mm, so that the space on the side of the blower 2 away from the inner wall of the handle housing 1 is sufficient to accommodate the arranged functional components, and the smoothness of the air flow sucked by the blower 2 can be ensured. If the axis of the blower 2 is offset too much relative to the axis of the handle housing 1, it is not conducive to the blower 2 sucking air flow. If the offset is too little, the space on the side of the blower 2 away from the inner wall of the handle housing 1 may be insufficient.

[0034] Further, an air inlet 101 is formed on the handle housing 1, and an axial section extending along the axis direction in the handle housing 1 forms an air inlet duct, and the air inlet duct is respectively communicated with the air inlet 101 and the blower 2. The blower 2 is used to suck air flow into the air inlet duct from the air inlet 101.

[0035] With such a setting, when the blower 2 starts to operate, the external air flow is sucked into the handle housing 1 through the air inlet 101, and the air flow is diverted to the blower 2 through the air inlet duct.

[0036] Further, see Figure 2 and Figure 3 , the handle assembly further includes: a mounting plate 3 and a control assembly 4. The mounting plate 3 is arranged in the handle housing 1 and is located between the blower 2 and the air inlet 101. The control assembly 4 is fixed on the mounting plate 3. A first air duct 5 is defined between the mounting plate 3 and the inner wall of the handle housing 1, and a second air duct 6 is defined between the side of the control assembly 4 facing away from the mounting plate 3 and the inner wall of the handle housing 1. The first air duct 5 and / or the second air duct 6 constitute the air inlet duct.

[0037] Since the handle housing 1 is relatively small in shape, the mounting plate 3 can be arranged parallel to the axis of the handle housing 1 and suspended in the handle housing 1, so as to fix the relatively large control component 4 on the mounting plate 3. Moreover, the control component 4 and the mounting plate 3 are arranged between the blower 2 and the air inlet 101. First, it is convenient for the control component 4 to be electrically connected to the blower 2; second, after the air flow enters the handle housing 1 through the air inlet 101, it first flows through the control component 4 and then flows to the blower 2, which can effectively dissipate heat from the control component 4. Among them, the control component 4 may include a power supply board and a control board.

[0038] Moreover, a first air duct 5 is formed between the mounting plate 3 and the inner wall of the handle housing 1, and a second air duct 6 is formed between the side of the control component 4 facing away from the mounting plate 3 and the inner wall of the handle housing 1. According to the design of the position of the air inlet 101, the first air duct 5 or the second air duct 6 constitutes the air inlet duct, or, the first air duct 5 and the second air duct 6 together constitute the air inlet duct. Since the blower 2 is eccentrically arranged, the blower 2 can be closer to the first air duct 5 or the second air duct 6, the diversion port is increased, so that the air flow passes through the air inlet duct larger and more smoothly, and at the same time the generated noise is relatively reduced, effectively improving the air inlet efficiency and the mute effect of the blower 2.

[0039] According to some specific embodiments of the present invention, the air inlets 101 are circumferentially distributed on the handle housing 1 and axially distributed along the handle housing 1, and at least part of the mounting plate 3 overlaps with the air inlets 101 in the axial direction of the handle housing 1.

[0040] With such a setting, see Figure 2 , one end of the handle housing 1 has air inlets 101 distributed circumferentially and axially, so that the air inlet area is relatively large. Moreover, at least part of the mounting plate 3 overlaps with the air inlets 101 in the axial direction of the handle housing 1, so that the side of the mounting plate 3 facing away from the control component 4 can guide the air flow to flow smoothly, reducing the air inlet resistance and avoiding the loss of the air inlet efficiency of the motor.

[0041] Furthermore, the side of the mounting plate 3 facing away from the control component 4 is a smooth surface, so that when the outer wall of the mounting plate 3 guides the air flow, the air inlet resistance can be reduced and the loss of the air inlet efficiency of the blower 2 can be avoided. Moreover, the outer wall of the end of the mounting plate 3 close to the blower 2 is an arc structure, which is conducive to guiding the air flow and can further reduce the air inlet resistance.

[0042] According to some specific embodiments of the present invention, the handle assembly further includes: a filter plate 8, and the filter plate 8 is arranged between the mounting plate 3 and the blower 2 for combing the incoming air flow so that the air flow flows into the blower 2 more evenly.

[0043] According to some specific embodiments of the present utility model, the handle assembly further includes: a filter screen (not shown in the drawings), which is disposed around one side of the mounting plate 3 adjacent to the air inlet 101 for filtering dust and other impurities.

[0044] According to some specific embodiments of the present utility model, the axis of the blower 2 is offset towards the side of the first air duct 5 relative to the axis of the handle housing 1.

[0045] With such a setting, the blower 2 is eccentrically arranged to be close to the first air duct 5, so that the first air duct 5 serves as the main air diversion duct, enabling more air to flow smoothly through the first air duct 5, thereby improving the air intake efficiency and noise reduction effect of the blower 2. The second air duct 6 can serve as a secondary air diversion duct, which can not only divert external air to the blower 2 but also dissipate heat from the control assembly 4.

[0046] Furthermore, the mounting plate 3 is offset towards the side of the second air duct 6 relative to the axis of the handle housing 1.

[0047] With such a setting, the mounting plate 3 is offset towards the side of the second air duct 6, making the ventilation cross-sectional area of the first air duct 5 larger and the air diversion opening larger, so that the air flow is larger and smoother through the first air duct 5, and the generated noise is greatly reduced, effectively improving the air intake efficiency and noise reduction effect of the blower 2.

[0048] According to some embodiments of the present utility model, the handle assembly further includes: a key member 7, which is disposed on the handle housing 1, and the key member 7 is installed on the side of the blower 2 away from the inner wall of the handle housing 1.

[0049] With such a setting, see Figures 1-3 , at least two key members 7 are installed on the handle housing 1, which may include a power key and a gear adjustment key. The space on the side of the blower 2 away from the inner wall of the handle housing 1 is used to install the key member 7, making the overall structure of the handle assembly compact and small in size, meeting the current miniaturized design and being convenient to carry.

[0050] A hair care appliance according to the second aspect embodiment of the present utility model includes: a handle assembly. The handle assembly is disposed on the hair care appliance for the user to operate and hold, facilitating the user to perform hair care.

[0051] Exemplarily, the handle assembly is the handle assembly of a hair dryer. It can be understood that in other embodiments, the handle assembly can also be the handle assembly of other hair care appliances such as a hair curler, without specific limitation.

[0052] According to the handle assembly of the present utility model, by eccentrically arranging the blower 2 inside the handle housing 1, the following advantages are achieved: First, a relatively large space is provided on the side of the blower 2 away from the inner wall of the handle housing 1, and this space provides an installation space for arranging functional components such as the button member 7, making the overall structure compact and having a small volume; Second, the blower 2 and the inner wall of the handle housing 1 jointly form an air inlet duct with almost no bending, and the air suction is relatively smooth, which is beneficial to improving the air inlet efficiency; Third, the limited space inside the handle housing 1 can be utilized, and the contact area between the blower 2 and the handle housing 1 or the connecting component for fixing the blower 2 is relatively small, so that the heat dissipation performance of the blower 2 is good to ensure stable and reliable operation.
