DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0035] Embodiment 1

[0036] Reference Figures 1-6 .

[0037] A pincurling device characterized in that it comprises a housing 1;

[0038] A mesh cover 03 is threadedly connected with the housing 1 to form a curling chamber 3,

[0039] A second cover 04 is sleeved on the periphery of the mesh cover 03 and is threadedly connected with the housing 1 to form a pincurling chamber 4, which surrounds the curling chamber 3;

[0040] A blade assembly 5 is arranged in the curling chamber 3, which comprises a blade holder 53 and a floating blade 52;

[0041] The side wall of the curling chamber 3 is provided with a communication groove 31 to enable the pincurls to pass through the curling chamber 3 and enter the pincurling chamber 4;

[0042] The blade holder 53 is provided with a fan blade 51, which forms an included angle a with the cross section of the rotating shaft of the driving assembly 2, the included angle a is less than ninety degrees and the opening is directed to the rotating direction of the blade assembly 5, and the vertex of the included angle a is located at the end of the fan blade 51;

[0043] The fan blade 51 is partially located below the blade holder 53 and partially located between the blade holder 53 and the blade edge.

[0044] The pincurling device has been updated for a long time, and in a better style, the curling chamber 3 containing the blade assembly 5 and the pincurling chamber 4 collecting the pincurls are arranged respectively, the pincurling chamber 4 surrounds the curling chamber 3 peripherally, the side wall of the curling chamber 3 is provided with a communication groove 31, when curling, the pincurls are cut down by the blade when passing through the mesh cover 03 and fall into the curling chamber 3, and then the pincurls are blown into the pincurling chamber 4 by the fan blade 51.

[0045] The problem is that the fan blades 51 in the prior art cannot effectively blow the hairballs into the hairball bin 4. By analyzing the features of the prior art, it is found that the fan blades 51 in the prior art are all perpendicular to the bottom surface of the trimming bin 3. Some better designed products will set the fan blades 51 as a curve, but the height direction is still perpendicular to the bottom surface of the trimming bin 3. The fan blades 51 are set as a curve to let the airflow spread in the radial direction, so as to blow the hairballs into the hairball bin 4. However, the prior art ignores the upward airflow (hereinafter referred to as axial airflow) generated when the blade rotates, which makes it difficult for the hairball to enter the blowing area (hereinafter referred to as radial airflow) of the fan blade 51. At the same time, even if the hairball enters the radial airflow area of the fan blade 51, due to the axial airflow formed above the radial airflow area by the blade, the hairball is attracted upward to form a vortex state, which results in that only a small amount of energy in the central area of the radial airflow blows the hairball radially, and the bottom surface of the trimming bin 3 and the bottom surface of the hairball bin 4 are usually above the blade when the hairball trimmer is in use. Further, the hairball continues to be driven and aggregated in the radial airflow, and when the hairball aggregation is too large, the large hairball is easy to block the communication groove 31 even if it spreads in the radial direction to the area where the radial airflow can act.

[0046] In this application, as shown in Figure 5 The angle a formed by the fan blade 51 and the cross section of the rotating shaft of the driving assembly 2 is less than ninety degrees, and the opening is directed to the rotating direction of the blade assembly 5. It is well known that an electric fan blows forward, and if it is reversed, it will blow backward. The fundamental reason lies in the relationship between the angle of the fan blade 51 and the rotating direction. In this application, the angle a formed by the fan blade 51 can blow air toward the bottom surface of the trimming bin 3 when the blade assembly 5 rotates. In this application, the fan blade 51 is not only located below the blade holder 53, but also a part is located above the blade holder 53. This part of the fan blade 51 needs to be located below the cutting edge of the floating blade 52 to avoid the cutting edge normally trimming the hairball. During the trimming process, the fan blade 51 is equivalent to the fan blade 51 of a dust collector (here it is equivalent to the dust collector, which means that the airflow direction is consistent with that of the dust collector, not the function of the dust collector). It overcomes the axial airflow generated by the outward blowing of the floating blade 52 during rotation, and changes the axial airflow to suction air into the trimming bin 3. That is, the mesh holes of the mesh cover 03 act as air inlets, the ventilation holes 41 of the side wall in the hairball bin 4 act as air outlets, and the communication groove 31 can be equivalent to an air duct. Accordingly, the hairball will also continuously enter the hairball cavity through the communication groove 31 along with the airflow. Since the hairball is very fluffy, it is usually not worried about the hairball blocking the ventilation hole 41 under normal circumstances.

[0047] The application optimizes the airflow path of the hairball trimmer so that the hairball can continuously enter the hairball bin 4, avoiding the accumulation of hairballs in the central area of the trimming bin 3 to form a large hairball mass, causing the communication groove 31 to be blocked, so that the user does not need to frequently open the trimming bin 3 to expose the blade, avoiding the blade from scratching the user while saving time and effort in cleaning the hair appliance.

[0048] More specifically, the driving assembly 2 is an electric motor 21, a power supply 22, and corresponding circuit boards 23 and control switches 24.

[0049] More specifically, the housing 1 includes a head 11 and a grip 12, the driving assembly 2 is arranged in the grip 12, and the end surface of the head 11, i.e. the bottom surface of the trimming bin 3, has a ring-shaped protrusion protruding therefrom to form the side wall of the trimming bin 3.

[0050] More specifically, the power supply 22 is a battery, and the driving assembly 2 has a charging port 25 connected to an external power supply 22 to charge the power supply 22.

[0051] Embodiment 2

[0052] Reference Figures 1-6 .

[0053] The side wall of the hairball bin 4 is provided with a ventilation hole 41 that communicates with external air and blocks the passage of hairballs, and the ventilation hole 41 is located above the communication groove 31;

[0054] Wherein, the top surface near the mesh cover 03 is the upper side, and the bottom surface near the trimming bin 3 is the lower side.

[0055] The air entering the hairball trimmer cannot always stay in the trimming bin 3 or the hairball bin 4. In Embodiment 1, the air can flow out through the gap at the connection site, but the air outlet area of the connection gap is small and uncontrollable. To this end, this embodiment provides a ventilation hole 41 for air outlet.

[0056] The ventilation hole 41 is arranged in the second cover body 04, and a plurality of ventilation holes 41 are arranged, and the plurality of ventilation holes 41 are concentrated in a ventilation area 411, and the ventilation area 411 occupies an area of less than 90° of the circumferential wall surface of the second cover body 04.

[0057] The hairball bin 4 is provided with a partition plate 42, the partition plate 42 is located in front of the ventilation area 411, the partition plate 42 is also provided with the ventilation hole 41, and the partition plate 42 divides the annular cavity of the hairball bin 4.

[0058] The front of the ventilation area 411 is the last position passed by the airflow after entering the ventilation area 411.

[0059] When the hairballs enter the hairball warehouse 4, the airflow can leave the hairball warehouse 4 from the air vents, but the hairballs cannot leave the hairball warehouse 4, which will cause the subsequent incoming hairballs to further push the hairballs at the air vent position to move, that is, to rotate along the hairball warehouse 4, and in the process of rotation, there is a possibility that the hairballs will leave the hairball warehouse 4 again. If this phenomenon occurs in the initial stage of trimming, it will not have much impact. The fan blade 51 continues to rotate for a period of time, and the hairballs will naturally return to the hairball warehouse 4. If this phenomenon occurs in the process of approaching the end of trimming, the blade assembly 5 is about to stop, and then these hairballs can only be cleaned separately by opening the trimming warehouse 3, and the hairballs coming out of the hairball warehouse 4 are basically large hairballs formed by the aggregation of multiple small hairballs, which are more necessary to be cleaned.

[0060] To this end, the air vents 41 in this application are not uniformly distributed around the hairball warehouse 4, but are concentrated in an area, that is, the air vent area 411, as shown in Figure 1 and Figure 6 The multiple air vents 41 of the entire air vent area 411 are regarded as an air outlet, and the airflow will concentrate the hairballs at various positions in the hairball warehouse 4 to the air vent area 411. Then, as shown in Figure 1 and Figure 3 In this embodiment, a partition plate 42 is provided, and the partition plate 42 is also provided with air vents 41, and the partition plate 42 is arranged in front of the air vent area 411, that is, the airflow wants to enter the air vent area 411 and then continue to flow forward. The partition plate 42 can block the hairballs near the air vent area 411. The partition plate 42 separates the cavity of the hairball warehouse 4, so the hairballs will accumulate in front of the partition plate 42, and the airflow will pass through the air vents 41 of the partition plate 42 without being disturbed.

[0061] More specifically, since the partition plate 42 has many air vents 41, it will be difficult to clean the partition plate 42, and after long-term use, the air vents 41 on the partition plate 42 will be blocked to a greater or lesser extent. To this end, the partition plate 42 is arranged as a detachable part, which can be removed for cleaning, and the second cover body 04 can be washed with water to clean the air vents 41.

[0062] Further, the partition plate 42 is provided with N, and the N partition plates 42 separate the hairball warehouse 4 into N chambers, and the communication groove 31 is provided with N, which respectively communicates the N chambers; the air vent area 411 is provided with N, which is respectively located in the N chambers; 4≥N≥2.

[0063] The ball pocket 4 is a ring-shaped chamber, and the hair balls will be concentrated at the position of the partition plate 42. In normal circumstances, the hair balls cleaned are not enough to block the air vents 41, but if the hair balls are not cleaned after multiple trims, or a large amount of hair balls need to be trimmed at one time, it is very likely to block the air vents 41, and the air flow area will be reduced, which will affect the air flow and make it difficult for the air flow to carry the hair balls into the ball pocket 4.

[0064] In this embodiment, N partition plates 42 are arranged to divide the ball pocket into N chambers, so that each chamber uniformly shares the hair balls and fully utilizes the volume of the ball pocket 4. That is, there are only a small amount of hair balls at the position of each partition plate 42, and even if a large amount of hair balls are trimmed, each partition plate 42 will only have 1 / N of the amount of hair balls that a single partition plate 42 originally has, and it is not easy to block. When the number of ventilation areas 411 and communication grooves 31 is increased, the ventilation area of each ventilation area 411 and communication groove 31 needs to be reduced accordingly.

[0065] Embodiment 3

[0066] Referring to Figures 1-6 .

[0067] The trimming chamber 3 is provided with a guide slope 32, which is a conical surface. The axis of the guide slope 32 is coaxial with the rotation axis of the blade assembly 5, and the bottom surface of the guide slope 32 is attached to the bottom surface of the trimming chamber 3.

[0068] In this application, the fan blades 51 can blow air towards the bottom surface of the trimming chamber 3, but the air flow also needs to enter the communication grooves 31 in the side wall of the trimming chamber 3, so the air flow needs to be further radially diffused. The air flow vertically blowing towards the bottom surface of the trimming chamber 3 will produce obvious turbulence, which will slow down the air flow, thereby affecting the effect of carrying the hair balls. Therefore, in this application, a guide slope 32 is arranged, which is directly integrated with the shell 1 (i.e. the bottom surface of the trimming chamber 3). The guide surface is a conical surface, and is coaxial with the rotation axis of the blade assembly 5. The bottom surface of the guide slope 32 is attached to the bottom surface of the trimming chamber 3. Here, the bottom surface of the guide slope 32 refers to the bottom surface of the conical structure, which has the largest diameter. The edge of the bottom surface is close to the communication grooves 31 (i.e. the edge of the trimming chamber 3). That is, the air flow will gradually diffuse along the conical surface towards the edge of the trimming chamber 3. The small diameter of the top of the conical surface can better guide the air flow towards the generatrix direction of the cone, reducing the energy loss when the air flow changes direction.

[0069] Embodiment 5

[0070] Referring to Figures 1-6 .

[0071] Two protection switches 6 are included, and one of the protection switches 6 is triggered when the mesh cover 03 is connected to the shell 1.

[0072] The second cover 04 is connected with the shell 1 to trigger one of the protection switches 6, and the hair clipper can be started only when both of the protection switches 6 are triggered.

[0073] In the prior art, the protection switch 6 is arranged in the hair clipper to prevent the mesh cover 03 from being opened, and the driving assembly 2 drives the blade assembly 5 to rotate, which is mainly to prevent the blade assembly 5 from flying out and ensure the safety of the user. In the embodiment, the protection switch 6 is arranged in the hair ball bin 4, and the protection switch 6 is triggered when the second cover 04 is connected with the shell 1.

[0074] The second cover 04 is opened only when the mesh cover 03 and the shell 1 are connected, and the blade assembly 5 cannot fly out even if the device is started, so as to not affect the safety of the user. However, after the second cover 04 is separated from the shell 1, that is, the hair ball bin 4 is opened, if the blade assembly 5 is started at this time, the fan blade 51 will blow away the hair balls in the hair ball bin 4, which greatly affects the use of the user.
