Description

Technical Field

[0001] This utility model relates to the technical field of diaphragm support, and in particular to a pet brush head with vibration function. Background Technology

[0002] As people's economic level continues to improve, more and more people are starting to keep pets such as cats or dogs. Many breeds of these pets have thick fur, requiring frequent grooming. There are pet brushes available on the market that owners can use to comb and clean their pets' fur.

[0003] In traditional pet brush head designs, the vibration function often relies on gear transmission mechanisms (such as eccentric gears or gear sets). This type of design faces significant technical bottlenecks, as follows:

[0004] 1. High mechanical loss: Gear meshing is prone to frictional loss, resulting in unstable vibration frequency and significantly increased noise after long-term use.

[0005] 2. Complex structure: The multi-stage gear assembly increases the internal space occupied by the brush head, resulting in a bulky device, and the gear lubrication requirements pose a safety hazard to pets.

[0006] 3. High maintenance costs: After the gears wear out, they need to be disassembled and replaced with professional tools, which makes it difficult for users to maintain them themselves, indirectly increasing the cost of use. Utility Model Content

[0007] The present invention aims to overcome the shortcomings of high mechanical wear in existing vibrating brush heads by providing a vibrating pet brush head that reduces mechanical wear.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A vibrating pet brush head, comprising:

[0010] The brush head body has an inlet, a massage comb, and a nozzle on its front side. The inlet is located above the massage comb, and the nozzle is located below the massage comb. Both the massage comb and the nozzle are detachably connected to the brush head body.

[0011] The suction channel is located inside the back of the brush head body and is connected to the suction port;

[0012] The vibrating chamber is located inside the brush head body, the suction channel is located at the back of the vibrating chamber, the massage comb is located at the front of the vibrating chamber, and the back of the vibrating chamber is provided with a vent that communicates with the suction channel;

[0013] The fan wheel is rotatably connected to the ventilation opening at its top center, and several evenly distributed guide vanes are fixed to its bottom edge and located inside the vibration chamber.

[0014] Several air inlets are located on the side wall of the vibration chamber and are evenly distributed around the bottom of the fan wheel. The air inlets are connected to the ventilation openings and correspond to the guide vanes.

[0015] An eccentric wheel, with a central shaft, is fixedly connected to the center of the fan wheel via the central shaft and is suspended in the vibrating chamber. The eccentric wheel is located at the bottom of the fan wheel. The brush head body is connected to the wastewater pipe on the main unit. The negative pressure generated by the main unit causes several air inlets to draw in external airflow. The external airflow acts on several guide vanes to drive the fan wheel to rotate. The fan wheel drives the eccentric wheel to rotate in the vibrating chamber via the central shaft, thereby causing the brush head body to vibrate. This provides a vibrating massage to the pet using the massage comb. This toothless structure replaces gears, achieving the purpose of reducing mechanical wear and simplifying maintenance. Finally, the external airflow enters the suction channel through the vent. The structure is simple. At the same time, the dirt sucked in through the suction port is collected in the main unit through the suction channel.

[0016] Preferably, the fan wheel includes a disc, the center of which is arched upwards to form a boss, and the connection between the boss and the disc forms a uniformly rounded corner to reduce noise when airflow passes through. A guide vane is fixedly connected to the edge of the disc, and several guide vanes are evenly distributed along the circumference of the disc. Both the guide vane and the boss protrude from the top of the disc. One end of the central shaft passes through the center of the boss and is rotatably connected to the vent. The part of the central shaft that passes through the center of the boss is detachably and fixedly connected to the boss. The other end of the central shaft is detachably and fixedly connected to an eccentric wheel, which is suspended at the bottom of the disc.

[0017] Preferably, the back of the vibrating chamber is provided with a circular groove that matches the wheel. The guide vane is located between the bottom of the circular groove and the top of the wheel. The vent is located at the center of the bottom of the circular groove. The boss is located inside the vent and forms a gap with the side wall of the vent to facilitate the passage of airflow. The bottom of the wheel is located inside the opening end of the circular groove. One end of the vent is located inside the suction channel and away from the vibrating chamber. The other end of the vent is close to the vibrating chamber. A support block is provided inside the vent. One end of the support block is fixedly connected to the side wall of the vent and away from the nozzle. The other end of the support block is suspended and located inside the end of the vent away from the vibrating chamber and does not connect with the edge of the vent, so that external airflow can enter the suction channel through the vent. The suspended end of the support block is close to the nozzle. One end of the central shaft passes through the center of the boss and is rotatably connected to the support block. The central shaft is located at the center of the vent. The circular grooves have two advantages. First, after several air inlets draw in external airflow, most of the airflow can act on several guide vanes, which helps to increase the strength of the force driving the fan wheel to rotate and improve the vibration effect. Second, they help to reduce noise.

[0018] Preferably, the inner side of the first guide vane is arc-shaped and its outer side is V-shaped, together forming a crescent-shaped structure. The outer bend of the first guide vane forms a rounded corner. The inner side of any one of the first guide vanes and the outer side of its adjacent first guide vane together form an air inlet channel. The air inlet is connected to the vent through the air inlet channel. The air inlet is arranged at an angle, with one end close to the air inlet channel and located on the side wall of the circular groove, and the other end away from the air inlet channel and passing through the side wall of the groove, located on the outer wall of the brush head body. The structural design of the first guide vane facilitates the intake of external airflow from several air inlets under negative pressure, allowing it to act on the inner side of the first guide vane, thereby further increasing the intensity of the driving force for the rotation of the wheel and reducing noise.

[0019] Preferably, several guide vanes (secondary) are fixed to the bottom of the circular groove. These guide vanes (secondary) are evenly distributed around the vent, centered on it. The guide vanes (secondary) are located between the boss and the first guide vane (primary) and correspond to it. The guide vanes (secondary) are arc-shaped, with their concave direction opposite to that of the first guide vane (primary). The arc of the guide vanes (secondary) is greater than that of the first guide vane (primary). This design of the guide vanes (secondary) concentrates the airflow after the rotating wheel towards the center of the vent, allowing it to be drawn out through the suction channel, thus reducing the risk of backflow of contaminants sucked in through the suction inlet into the vibration chamber.

[0020] Preferably, one side of the massage comb is embedded in the brush head body and detachably fixed to it. The corresponding other side of the massage comb is the massage surface, located on the outer side of the brush head body. Several evenly distributed comb teeth are integrally formed on the massage surface. The comb teeth are hemispherical or cylindrical in shape, and both the comb teeth and the massage surface are made of silicone. The flexible conduction of the silicone massage surface and the comb tooth design effectively loosen stubborn stains with a constant amplitude, while providing a stable and comfortable massage experience for pets, reducing stress reactions.

[0021] Preferably, the suction inlet and the comb teeth are vertically aligned, with both the suction inlet and the massage comb located away from the suction channel. The nozzle is close to the suction channel. A connecting channel is located at the upper end of the brush head body, and this connecting channel is vertically distributed with and isolated from the vibration chamber. The suction inlet is connected to the suction channel via the connecting channel. A connecting pipe is fixed at the lower end of the brush head body, located on the back of the brush head body. One side of the connecting pipe is connected to the suction channel, while the other side is isolated from it and forms a gap with the brush head body. One end of the nozzle is inserted and fixed into the other side of the connecting pipe, while the other end is located within the gap and its spray direction is towards the massage comb. The end of the nozzle located within the gap is detachably fixed to the outer wall of the brush head body. During suction, under the negative pressure of the main unit, dirt is sucked in through the suction inlet, enters the suction channel through the connecting channel, and is finally collected in the main unit from one side of the connecting pipe. Simultaneously, the nozzle sprays clean water onto the pet's surface to improve cleaning effectiveness. The nozzle installation structure is conventional and will not be described in detail here.

[0022] The beneficial effects of this utility model are:

[0023] 1. External airflow acts on several guide vanes to drive the fan wheel to rotate. The fan wheel drives the eccentric wheel to rotate in the vibration chamber through the central shaft, thereby causing the brush head body to vibrate. The pet is then massaged by the massage comb. This toothless structure replaces gears, which helps to reduce mechanical wear and makes maintenance simple. Finally, the external airflow enters the suction channel through the vent. The structure is simple.

[0024] 2. It helps to increase the intensity of the force driving the fan wheel to rotate, thus improving the vibration effect;

[0025] 3. It helps with noise reduction;

[0026] 4. The design of the second guide vane will cause the airflow after the wheel rotates to converge again towards the center of the vent, so that it is drawn out from the suction channel, which helps to reduce the risk of dirt sucked in from the suction port flowing back into the vibration chamber; the flexible conduction of the silicone massage surface and the comb design can effectively loosen stubborn stains under constant amplitude, while providing pets with a stable and comfortable massage experience and reducing the resulting stress response in pets.
