Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically to a vacuum cleaner base station. Background Technology

[0002] The vacuum cleaner base station is an important component of the robotic vacuum cleaner system. It is responsible for providing charging services to the robotic vacuum cleaner, ensuring that it can continue cleaning. The base station has a built-in battery charging system, and when the robotic vacuum cleaner's battery is low, it will automatically return to the base station to recharge, ensuring that the robotic vacuum cleaner has enough power to continue working.

[0003] For example, a prior art (Chinese patent publication number: CN217408698U, publication date: 2022-09-13) describes a sweeping robot, comprising: a sweeping robot body; a battery mounting slot disposed at the bottom of the sweeping robot body with its opening facing away from the sweeping robot body, for mounting a battery assembly to power the sweeping robot; an electric fastening structure disposed inside the sweeping robot body for fixing the battery assembly to the battery mounting slot; and electrode plates disposed at the bottom of the sweeping robot body and electrically connected to the electric fastening structure. The electrode plates disposed inside the sweeping robot can be electrically connected to power supply contacts on a charging base station. The charging base station temporarily provides power to the sweeping robot, so that the electric fastening structure can, under the power supply, cooperate with the sweeping robot's battery replacement action to loosen or fix the battery assembly; and the data stored on the sweeping robot's motherboard will not be cleared, and it can also respond to external commands and information feedback.

[0004] In existing charging base stations, during the hair trimming and cleaning process, the hair is prone to getting tangled with the back of the blade, which affects the subsequent trimming operation of the blade.

[0005] Therefore, we propose a vacuum cleaner base station to address the aforementioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a vacuum cleaner base station to solve the problem mentioned in the background art that during the process of trimming and cleaning hair, the hair is easily entangled with the back of the blade, thereby affecting the subsequent trimming operation of the blade.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a vacuum cleaner base station, a charging base station housing, wherein a threaded transmission rod is provided inside the charging base station housing, and a shearing assembly is provided inside the charging base station housing, and the shearing assembly slides by the driving action of the threaded transmission rod, wherein the blade assembly in the shearing assembly includes an upper blade body and the side structure adjacent to its cutting edge is designed as a non-concave structure to prevent hair from getting stuck.

[0008] Furthermore, the shearing assembly includes a movable bracket, which is threadedly connected to the outside of the threaded transmission rod, and the end of the threaded transmission rod is connected to a motor assembly disposed inside the charging base station housing.

[0009] Furthermore, a drive wheel body is nested on the movable bracket, and a drive wheel spring is fixedly connected between the lower side of the drive wheel body and the movable bracket, and a zigzag rib is provided on the upper side of the drive wheel body.

[0010] Furthermore, the zigzag rib is fixedly connected inside the charging base station housing, and the zigzag rib has a zigzag structure design, with the upper surface of the drive wheel body fitting against the lower side of the zigzag rib.

[0011] Furthermore, the drive wheel body forms a sliding structure with the movable bracket through the tortuous ribs, and the drive wheel body forms an elastic structure with the movable bracket through the drive wheel spring.

[0012] Furthermore, the movable bracket is rotatably connected to the lower blade body, and the upper end of the lower blade body is fixedly connected to the interior of the movable bracket with a lower blade spring, and the lower blade body and the movable bracket form an elastic structure through the lower blade spring.

[0013] Furthermore, the outer side of the lower blade body is rotatably connected to the upper blade body, and the end side of the upper blade body is nested and connected to the movable bracket.

[0014] Furthermore, the length of the lower blade body is greater than the length of the upper blade body, and the lower blade body and the upper blade body form an acute angle when closed. At the same time, the non-curved surface on the upper blade body is set as an inclined surface, and the bottom end of the inclined surface of the upper blade body is inclined towards the blade direction of the lower blade body, which is used to guide the hair into the space between the two blades.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The motor assembly inside the charging base station housing drives the threaded transmission rod, which in turn drives the shearing assembly to move laterally. This causes the upper and lower blade bodies inside the shearing assembly to rotate in coordination, thereby trimming the hair and preventing the hair from getting tangled with the device.

[0017] 2. When the drive wheel body contacts the recessed area of ​​the zigzag rib, the drive wheel body does not drive the upper blade body to rotate downward. At this time, the upper blade body and the lower blade body are in an open state. The hair is hooked by the lower blade body and moves along the inclined surface of the lower blade body, which facilitates the subsequent trimming of the hair.

[0018] 3. When the drive wheel body comes into contact with the protrusion of the zigzag rib, the drive wheel body drives the upper blade body to rotate downward. The upper blade body and the lower blade body are in a closed state. The hair slides along the inclined surface of the upper blade body to the blade head of the lower blade body that is longer than the upper blade body. When the upper blade body and the lower blade body open, the hair moves along the inclined surface of the lower blade body and is cut off when the upper blade body and the lower blade body close again.

[0019] 4. The shearing assembly moves from right to left along the threaded drive rod. When the upper blade body is in a closed state between the upper blade body and the lower blade body, it forms an acute angle to prevent hair from slipping into the back of the upper blade body and to facilitate the guide of hair into the lower blade body.

[0020] 5. The drive wheel spring and the lower blade spring can be used to reset the drive wheel body and the lower blade body, thereby realizing the reciprocating operation of the shearing operation. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1: As Figure 1 and Figure 2 The technical solution shown herein provides the following technical solution: A vacuum cleaner base station, comprising a threaded drive rod 10, which drives the shearing assembly 2 to perform shearing operations:

[0030] A charging base station housing 1, with a threaded transmission rod 10 inside the charging base station housing 1, characterized in that: a shearing assembly 2 is provided inside the charging base station housing 1, and the shearing assembly 2 slides by being driven by the threaded transmission rod 10, and the upper blade body 6 included in the blade group of the shearing assembly 2 and the side structure adjacent to its cutting edge are designed as a non-concave structure to prevent hair from getting stuck.

[0031] The shearing assembly 2 includes a movable bracket 3, which is threaded to the outside of the threaded transmission rod 10. The end of the threaded transmission rod 10 is connected to the motor assembly inside the charging base station housing 1. A drive wheel body 4 is nested on the movable bracket 3. A drive wheel spring 8 is fixedly connected between the lower side of the drive wheel body 4 and the movable bracket 3. A tortuous rib 5 is provided on the upper side of the drive wheel body 4. The tortuous rib 5 is fixedly connected inside the charging base station housing 1. The tortuous rib 5 has a tortuous structure design. The upper surface of the drive wheel body 4 is in contact with the lower side of the tortuous rib 5. The drive wheel body 4 and the movable bracket 3 form a sliding structure through the tortuous rib 5. The drive wheel body 4 and the movable bracket 3 form an elastic structure through the drive wheel spring 8.

[0032] The motor assembly inside the charging base station housing 1 drives the threaded transmission rod 10, which in turn drives the shearing assembly 2 to move laterally. This causes the upper blade body 6 and the lower blade body 7 inside the shearing assembly 2 to rotate in coordination, thereby trimming the hair and preventing the hair from getting tangled with the device. The elastic force of the drive wheel spring 8 and the lower blade spring 9 can reset the drive wheel body 4 and the lower blade body 7, thus realizing the reciprocating operation of the shearing operation.

[0033] Example 2: Figure 1 , Figure 3 and Figure 6 The technical solution shown herein provides the following technical solution: a vacuum cleaner base station, wherein the upper blade body 6 and the lower blade body 7 are in an open state, which can initially limit the movement of hair:

[0034] The movable bracket 3 is rotatably connected to the lower blade body 7, and the upper end of the lower blade body 7 is fixedly connected to the interior of the movable bracket 3 with a lower blade spring 9. The lower blade body 7 and the movable bracket 3 form an elastic structure through the lower blade spring 9. The outer side of the lower blade body 7 is rotatably connected to the upper blade body 6, and the end of the upper blade body 6 is nested on the movable bracket 3. The length of the lower blade body 7 is greater than the length of the upper blade body 6, and the lower blade body 7 and the upper blade body 6 form an acute angle when closed. At the same time, the non-curved surface on the upper blade body 6 is set as an inclined surface, and the bottom end of the inclined surface of the upper blade body 6 is inclined towards the blade direction of the lower blade body 7 to guide the hair into the space between the two blades.

[0035] When the drive wheel body 4 comes into contact with the recessed area of ​​the zigzag rib 5, the drive wheel body 4 does not drive the upper blade body 6 to rotate downward. At this time, the upper blade body 6 and the lower blade body 7 are in an open state. The hair is hooked by the lower blade body 7 and moves along the inclined surface of the lower blade body 7, which facilitates the subsequent trimming of the hair.

[0036] Example 3: Figure 2 , Figure 4 and Figure 5 The technical solution shown herein provides the following technical solution: A vacuum cleaner base station, which discloses that when the upper blade body 6 and the lower blade body 7 are open, hair can be introduced:

[0037] When the drive wheel body 4 contacts the protrusion of the zigzag rib 5, the drive wheel body 4 drives the upper blade body 6 to rotate downward. The upper blade body 6 and the lower blade body 7 are in a closed state. The hair slides along the inclined surface of the upper blade body 6 to the blade head of the lower blade body 7 that is longer than the upper blade body 6. When the upper blade body 6 and the lower blade body 7 open, the hair moves along the inclined surface of the lower blade body 7 and is cut off when the upper blade body 6 and the lower blade body 7 close again.

[0038] The shearing assembly 2 moves from right to left along the threaded drive rod 10. When the upper blade body 6 is in a closed state between the upper blade body 6 and the lower blade body 7, it forms an acute angle to prevent hair from slipping into the back of the upper blade body 6 and to facilitate the guide of hair into the lower blade body 7.
