Technical Field
[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a combination pet vacuum cleaner with easy-to-change nozzles. Background Technology
[0002] With the increasing popularity of pet-owning households, pet vacuum cleaners specifically designed to clean pet hair and debris have become essential appliances for many families. To handle different cleaning scenarios, such as floors, fabric surfaces, or crevices, these vacuum cleaners are usually equipped with a variety of interchangeable nozzles that users can combine as needed.
[0003] In practical use, most existing vacuum cleaners connect their nozzles to the body using simple friction-fit or snap-fit structures. Friction-fit connections are prone to loosening or becoming too tight after frequent disassembly and reassembly, affecting user experience and connection reliability. While traditional snap-fit structures are relatively sturdy, they usually require both hands to operate and are inconvenient when aligning and pressing the snaps. This can frequently interrupt the cleaning process, especially during cleaning sessions that require frequent nozzle changes, thus reducing overall efficiency.
[0004] More importantly, pets' living environments are often quite complex, including corners of pet cages, multi-tiered platforms of cat trees, and crevices under sofas and furniture. Cleaning these areas requires not only changing the appropriate nozzle but also constantly adjusting the cleaning angle. Current technology typically relies on users manually twisting their wrists or the entire device to change the angle, which is extremely inconvenient in confined spaces, laborious, and often leaves cleaning blind spots due to limited angle. Existing technology fails to effectively combine the two core needs of "easy nozzle replacement" and "flexible angle adjustment," resulting in users still finding the operation cumbersome and inefficient when faced with complex pet environment cleaning tasks.
[0005] Therefore, this utility model proposes a modular pet vacuum cleaner with easy-to-change nozzles to address the shortcomings of the prior art. Utility Model Content

[0007] This utility model provides a modular pet vacuum cleaner with easy-to-change nozzles, including: a body, a dust collection chamber, a nozzle interface, and a nozzle; the dust collection chamber is rotatably connected to the front end of the body, the nozzle interface is located at the front end of the dust collection chamber, and the nozzle is detachably installed on the nozzle interface; the vacuum cleaner also includes a quick-release mechanism on the nozzle interface and a rotating mechanism between the body and the dust collection chamber.
[0008] The quick-release mechanism includes a sliding cover that is slidably sleeved on the outer wall of the suction head interface. A ball bearing is provided in the cavity of the suction head interface, and a limiting groove is provided on the outer wall of the suction head for the ball bearing to engage.
[0009] Furthermore, the rotating mechanism includes a motor fixed to the rear end of the dust collection bin. The motor drives one of the internal meshing gears, and through the meshing transmission of the internal meshing gears, ultimately drives the dust collection bin to rotate relative to the machine body.
[0010] Preferably, the quick-release mechanism further includes a spring sleeved on the outside of the suction head interface and a metal retaining ring fixed to the front end of the sliding cover.
[0011] Preferably, the spring is located between the sliding cover and the dust collection chamber, and the two ends of the spring abut against the rear end face of the sliding cover and the front end face of the dust collection chamber, respectively, to provide a restoring force.
[0012] Preferably, the inner diameter of the metal retaining ring is smaller than the outer diameter of the suction head interface, in order to prevent the sliding cover from sliding off the suction head interface.
[0013] Preferably, the rotating mechanism further includes a rotating shaft and a fixed shaft; wherein, the output shaft of the motor is fixedly connected to the rotating shaft, and the rotating shaft is fixedly connected to the second internal meshing gear; while the first internal meshing gear is fixed on the dust collection bin and meshes with the second internal meshing gear.
[0014] Preferably, the front end of the fixed shaft is fixed to the rear end of the dust collection bin, and its rear end is rotatably connected to the front end of the machine body, and the internal meshing gear II rotates around the axis of the fixed shaft.
[0015] Preferably, the rear end of the dust collection bin is fixedly connected to an insert ring, which is engaged with the front end of the machine body, and the entire rotating mechanism is located inside the insert ring.
[0016] Preferably, the ball bearings in the suction head interface cavity are arranged radially movable, and the inner wall of the sliding cover is provided with an inclined surface or groove for pushing or releasing the ball bearings.
[0017] This utility model has the following beneficial effects:
[0018] 1.

[0019] 2. This utility model solves the problem that existing pet vacuum cleaners have difficulty cleaning complex areas such as corners of pet cages and furniture gaps due to the fixed angle of the suction head, resulting in cleaning dead corners and inconvenient operation. It achieves the technical effect of enabling the suction head to automatically adjust a wide range of angles, allowing users to easily clean narrow and irregular spaces without frequently adjusting their body posture, and effectively eliminating cleaning dead corners.
[0020] 3.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0031] Example:
[0032] Please refer to Figures 1 to 4 This utility model provides a modular pet vacuum cleaner with easy-to-change nozzles, which aims to solve the problems of cumbersome nozzle replacement and dead corners caused by the fixed nozzle angle in existing pet vacuum cleaners.
[0033] like Figure 1 As shown, the modular pet vacuum cleaner with easy-to-change nozzles includes a body 1 and a dust collection chamber 2 rotatably connected to the front end of the body 1. The body 1 serves as the handheld main body of the entire device and the mounting base for the internal power components. The front end of the dust collection chamber 2 is fixedly connected to a nozzle interface 3. The nozzle 5 is detachably installed on the nozzle interface 3. This structure, through a quick-release mechanism 4 set on the nozzle interface 3 and a rotating mechanism 6 set between the body 1 and the dust collection chamber 2, collaboratively realizes the functions of quick nozzle replacement and automatic adjustment of cleaning angle.
[0034] Please refer to Figure 1 , Figure 2 and Figure 3 The quick-release mechanism 4 is specifically constructed as follows: a sliding cover 41 is slidably sleeved on the outer wall of the suction head interface 3. A spring 42 is provided between the sliding cover 41 and the dust collection chamber 2. The two ends of the spring 42 abut against the rear end face of the sliding cover 41 and the front end face of the dust collection chamber 2, respectively, to provide a restoring force. A metal retaining ring 43 is fixedly connected to the front end of the sliding cover 41. The inner diameter of the metal retaining ring 43 is smaller than the outer diameter of the suction head interface 3, which is used to axially limit the sliding cover 41 to prevent it from slipping off. A ball bearing 44 is radially movably arranged on the cavity wall of the suction head interface 3. The inner wall of the sliding cover 41 is provided with an inclined surface or groove for pushing or releasing the ball bearing 44. The suction head 5 is inserted into the outer wall of one end of the suction head interface 3, and a limiting groove 45 is provided for the ball bearing 44 to fall into and achieve locking.
[0035] Please refer to Figure 1 and Figure 4The specific structure of the rotating mechanism 6 is as follows: an embedded ring 65 is fixedly connected to the rear end of the dust collection chamber 2. The embedded ring 65 is engaged with the front end of the body 1. The components of the rotating mechanism 6 are housed inside the embedded ring 65. The rotating mechanism 6 includes a motor 64 fixedly installed at the rear end of the dust collection chamber 2, a fixed shaft 66 whose front end is fixed to the rear end of the dust collection chamber 2 and whose rear end is rotatably connected to the front end of the body 1, an internal meshing gear 61 fixed to the inner wall of the body 1, and an internal meshing gear 62 meshing with the internal teeth of the internal meshing gear 61. The output shaft of the motor 64 is fixedly connected to the internal meshing gear 62 through a rotating shaft 63. When the motor 64 is working, it drives the internal meshing gear 62 to rotate through the rotating shaft 63. Since the internal meshing gear 61 is fixed, the rotation of the internal meshing gear 62 will revolve around the axis of the fixed shaft 66, thereby driving the entire dust collection chamber 2 and the suction head 5 at the front end to rotate relative to the body 1.
[0036] To solve the above-mentioned technical problems, the core of the technical solution in this embodiment lies in the fact that the modular pet vacuum cleaner, which facilitates the replacement of the suction head, integrates functions through the structural cooperation between the quick-release mechanism 4 and the rotating mechanism 6. The core structure will be described in detail below:
[0037] Please refer to the following carefully. Figure 1 , Figure 2 and Figure 3 During the quick replacement of the suction head 5, when the sliding cover 41 of the quick-release mechanism 4 slides backward along the axial direction of the suction head interface 3, its rear end face compresses the spring 42. At the same time, the surface on the inner wall of the sliding cover 41 that restricts the radial movement of the ball 44 moves away, providing space for the ball 44 to move out radially. At this time, the suction head 5 is pulled out of the suction head interface 3 or a new suction head 5 is inserted into the suction head interface 3. When the suction head 5 is fully inserted, the limiting groove 45 on its outer wall is exactly aligned with the ball 44 on the cavity wall of the suction head interface 3. When the sliding cover 41 is released, the elastic force of the spring 42 pushes the sliding cover 41 forward to reset. After resetting, the inner wall of the sliding cover 41 presses the ball 44 back in and confines it in the limiting groove 45. This linkage locking structure of the sliding cover and the ball limiting groove ensures the firmness of the suction head 5 installation and the convenience of disassembly.
[0038] Please refer to the following carefully. Figure 1 and Figure 4During the automatic adjustment of the suction head 5 angle, after the motor 64 in the rotating mechanism 6 starts, its output shaft drives the rotating shaft 63 and the internal meshing gear 62 fixed on the rotating shaft 63 to rotate synchronously. Since the internal meshing gear 62 and the internal meshing gear 61 fixed on the inner wall of the body 1 always maintain an internal meshing state, the internal meshing gear 62 will also revolve around the internal gear ring of the internal meshing gear 61 while rotating on its own axis. This revolve motion is transmitted to the entire dust collection chamber 2 through the rotating shaft 63 and the motor 64, and finally drives the dust collection chamber 2, together with the suction head interface 3 and the suction head 5 at its front end, to rotate 360 degrees relative to the body 1. This internal meshing gear planetary transmission structure achieves a smooth and wide-range angle adjustment function with a compact layout.
[0039] Based on the above embodiments, the present invention may further include the following preferred technical solutions:
[0040] In a preferred embodiment, in order to provide reliable reset force and pre-tightening force to the sliding cover 41, the quick-release mechanism 4 also includes a spring 42 sleeved on the outside of the suction head interface 3 and a metal retaining ring 43 fixed to the front end of the sliding cover 41.
[0041] As another preferred embodiment, for a more specific definition of the reset structure, please refer to... Figure 2 Spring 42 is located between sliding cover 41 and dust collection chamber 2, and the two ends of spring 42 abut against the rear end face of sliding cover 41 and the front end face of dust collection chamber 2, respectively.
[0042] As another preferred embodiment, in order to prevent the sliding cover 41 from falling off during repeated sliding operations, the inner diameter of the metal retaining ring 43 is designed to be smaller than the outer diameter of the suction head interface 3. In this way, the metal retaining ring 43 can be blocked by the front flange of the suction head interface 3 when the sliding cover 41 is reset to the front end, thereby playing an effective limiting role.
[0043] As a preferred embodiment, to achieve compact installation and stable support of the rotating mechanism 6, please refer to... Figure 1 and Figure 4 The rotating mechanism 6 also includes a rotating shaft 63 and a fixed shaft 66. The output shaft of the motor 64 is fixedly connected to the rotating shaft 63. The rotating shaft 63 is fixedly connected to the second internal meshing gear 62. The first internal meshing gear 61 is fixed on the dust collection bin 2, and the first internal meshing gear 61 and the second internal meshing gear 62 mesh with each other.
[0044] As another preferred embodiment, in order to define the rotation center and provide stable rotation support, the front end of the fixed shaft 66 is fixed to the rear end of the dust collection bin 2, the rear end of the fixed shaft 66 is rotatably connected to the front end of the body 1, and the internal meshing gear 62 rotates around the axis of the fixed shaft 66.
[0045] As another preferred embodiment, in order to achieve a reliable rotational engagement between the body 1 and the dust collection chamber 2, an insert ring 65 is fixedly connected to the rear end of the dust collection chamber 2. The insert ring 65 is engaged with the front end of the body 1, and all components of the rotating mechanism 6 are located inside the insert ring 65.
[0046] As another preferred embodiment, in order to clarify the movement mode and implementation mechanism of the ball 44, the ball 44 in the cavity of the suction head interface 3 is designed to be radially movable. At the same time, a slope or groove is machined on the inner wall of the sliding cover 41 corresponding to the position of the ball 44. By axially moving the sliding cover 41, the slope or groove is used to guide the ball 44 to produce a radial contraction or release action.
[0047] The working principle is as follows:
[0048] When the suction head 5 needs to be replaced, slide the sliding cover 41 backward along the axial direction. As the sliding cover 41 moves backward, it will compress the spring 42 behind it. At the same time, the inner wall of the sliding cover 41 provides space for the ball 44 to move radially, so that the ball 44 can disengage from the limiting groove 45 of the suction head 5. At this time, the old suction head 5 can be pulled out, and after inserting the new suction head 5, the sliding cover 41 is released. The elastic force of the spring 42 pushes the sliding cover 41 to reset. The inner wall of the reset sliding cover 41 then presses the ball 44 into the limiting groove 45 of the new suction head 5 to complete the locking. The whole process does not require rotation or the use of tools, realizing quick replacement.
[0049] When the cleaning angle needs to be adjusted, the motor 64 located at the rear end of the dust collection chamber 2 is activated. The motor 64 drives the internal meshing gear 62 to rotate via the rotating shaft 63. Since the internal meshing gear 62 meshes with the internal meshing gear 61 fixed on the body 1, the internal meshing gear 62 will revolve around the internal gear ring of the internal meshing gear 61 while rotating. This revolve motion, through its fixed connection with the dust collection chamber 2, drives the entire dust collection chamber 2, together with the front suction head interface 3 and the suction head 5, to rotate around the fixed shaft 66 relative to the body 1, thereby automatically adjusting the suction angle and simplifying operation in complex spaces such as corners of pet cages and gaps in furniture.
