Technical Field

[0001] This invention relates to the field of pet oral hygiene products, and in particular to an electric pet toothbrush. Background Technology

[0002] As pets gain increasing importance in family life, their oral health is receiving more and more attention. Oral health in pets has long been neglected; plaque, tartar, and the resulting periodontal disease are common oral problems in cats, dogs, and other pets. Currently, common methods for cleaning pets' teeth or caring for their oral health include: manual finger toothbrushes or manual pet toothbrushes, which rely on the user's hand to rub the pet's teeth back and forth; dental chews, dental toys, and dental treats, which rely on the mechanical friction of chewing to provide some auxiliary cleaning effect; and dental sprays, mouthwashes, and dental gels, which rely on chemical ingredients to inhibit plaque or soften tartar.

[0003] However, all of the above methods have varying degrees of drawbacks: manual brushing is inefficient, time-consuming, and laborious, making it difficult to effectively remove plaque from between teeth and near the gum line. Furthermore, pets generally resist brushing and have low cooperation, making it difficult for users to precisely control the brush head's position and pressure within the pet's mouth, posing a risk of scratching the gums. Dental cleaning sticks, sprays, and gels can only play a supplementary role and cannot replace physical cleaning, and they are also ineffective at cleaning all surfaces of the teeth.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] This invention provides a pet electric toothbrush, such as... Figures 1 to 12 As shown, the pet electric toothbrush includes a body 1, a drive component 2, and a drive transmission structure 3; the body 1 is for the user's fingers 6 to attach or hold, and a brush head 4 is provided on the body 1; the drive component 2 and the drive transmission structure 3 are disposed inside the body 1, the drive component 2 is used to generate drive, and the drive transmission structure 3 is connected between the drive component 2 and the brush head 4, and is used to transmit the drive generated by the drive component 2 to the brush head 4 so that the brush head 4 performs cleaning action.

[0030] The electric toothbrush for pets of the present invention designs the body 1 in a form that allows the user's fingers 6 to attach or hold it, enabling the user to clean the pet's mouth in the most natural way. This retains the precise control feel of manual brushing to the greatest extent and effectively solves the problems of low pet cooperation, inconvenience of operation, and insufficient safety. At the same time, by setting a drive component 2 and a drive transmission structure 3 in the body 1, the driving force generated by the drive component 2 is transmitted to the brush head 4 through the transmission structure, so that the brush head 4 performs automated cleaning action. This replaces manual reciprocating friction with electric drive, which significantly improves cleaning efficiency and the ability to remove plaque between teeth and near the gum line. It achieves the technical goal of improving the oral cleaning effect of pets while taking into account both ease of operation and safety.

[0031] Specifically, in some optional embodiments, the body 1 can be further designed as a finger sleeve structure with a hollow structure, allowing the user's finger 6 to be inserted and worn, thus directly slipping the toothbrush onto the finger 6. This allows the position, angle, and pressure of the brush head 4 to be flexibly controlled entirely by the user's finger 6, making it particularly suitable for delicate oral procedures on uncooperative pets. Alternatively, the body 1 can also be a short-handled grip shell or a pen-shaped shell to accommodate different users' operating habits. The driving component 2 can be in the form of an ultrasonic transducer, a miniature high-frequency vibration motor, or a micro motor, correspondingly causing the brush head 4 to generate high-frequency micro-vibration, rotational motion, or reciprocating oscillation cleaning actions. The high-frequency micro-vibration is gentle on the gums and has strong cleaning power, while rotation or reciprocating oscillation can expand the cleaning coverage area. The drive transmission structure 3 can be configured as a transmission rod, an eccentric wheel mechanism, or a gear transmission mechanism, depending on the driving form, to ensure that the driving force is efficiently and stably transmitted to the brush head 4. In addition, the bristles on the brush head 4 can be made of soft rubber or nylon, and the shape of the brush head 4 can be designed as single-sided bristles, double-sided bristles, or U-shaped wrap-around brush head 4 to meet the different cleaning needs of pet teeth.

[0032] Specifically, in one embodiment, a finger sleeve 11 is provided on the main body 1, and the finger sleeve 11 is hollow to form an insertion cavity 111 for the user's finger 6 to be inserted. By providing a finger sleeve 11 on the main body 1 and designing the finger sleeve 11 as a hollow structure to form an insertion cavity 111 for the user's finger 6 to be inserted, the user can directly wear the toothbrush on their finger 6 for operation, thereby preserving the natural operating feel of brushing the pet's teeth with their finger 6 to the greatest extent. The user can directly confirm the position, angle, and pressure of the brush head 4 in the pet's mouth through their finger 6, achieving precise control of the brush head 4, effectively solving the problem of pets generally resisting brushing their teeth and having low cooperation, reducing the risk of scratching the pet's gums due to improper operation. At the same time, the finger sleeve wearing method is convenient for one-handed operation, especially suitable for oral cleaning of uncooperative pets. Specifically, the insertion cavity is a semi-enclosed structure or a fully enclosed structure.

[0033] The finger sleeve 11 can adopt an ergonomic arc-shaped sleeve structure, with its inner cavity contour conforming to the shape of the human index finger to ensure wearing comfort and stability. The material of the finger sleeve 11 can be silicone, rubber, or soft plastic, which have a certain elasticity and coefficient of friction to enhance the fit with the finger 6 and prevent slippage. The opening of the insertion cavity 111 can be set at the tail of the finger sleeve 11, and the edge of the opening can be designed as a flared or flanged structure to facilitate quick insertion of the finger 6. The inner surface of the finger sleeve 11 can be provided with anti-slip textures or raised dots to increase the friction between the finger and the skin of the finger 6. The length of the finger sleeve 11 can cover the range from the fingertip to the first or second finger joint of the user to balance operational flexibility and wearing stability. The outer surface of the finger sleeve 11 can be integrally formed with other parts of the body 1, or connected to the body 1 by means of buckles, adhesives, etc.

[0034] In another embodiment, the main body 1 is in the shape of a long handle for the user to hold. By designing the main body 1 as a long handle for the user to hold, the user can clean the pet's mouth in a way similar to holding a traditional toothbrush, expanding the product's target audience and meeting the needs of users accustomed to holding the brush. The long handle of the main body 1 extends the lever arm, making it easier for the user to insert the brush head 4 deep into the pet's mouth for cleaning, especially suitable for cleaning hard-to-reach areas such as the pet's back molars. At the same time, the long handle structure provides more installation space for internal components such as the drive unit 2, power supply components, and control circuit board, which is beneficial for optimizing the internal layout and improving product performance.

[0035] The long-handled body 1 can be designed as a cylindrical, elliptical, or polygonal column structure, and its cross-sectional dimensions can be consistent or gradually change along the length direction. For example, the grip area can be appropriately thickened to conform to ergonomics. The outer surface of the body 1 can be provided with anti-slip textures, grooves, or covered with an anti-slip soft rubber layer to enhance grip stability and prevent slippage during use.

[0036] The main body 1 has an overall arc shape. By designing the main body 1 into an arc shape, its outline conforms to the physiological curve of the pet's mouth and the natural curvature of the user's fingers 6 or palm. This facilitates the smooth insertion of the brush head 4 into the pet's mouth and cleaning along the direction of the teeth, reducing discomfort or damage to the pet's mouth caused by the rigid shape of the main body 1. The arc shape also improves the comfort of holding or wearing the brush, allowing the user to complete the brushing action in a more natural and effortless manner, further increasing the pet's acceptance and cooperation during the brushing process. The main body 1 can be made of soft silicone or rubber to enhance brushing comfort. The arc shape is a longitudinal arc bend along the length of the main body 1. The arc shape of the main body 1 can be achieved through injection molding or by combining flexible materials with a rigid frame, allowing the main body 1 to maintain its overall arc shape while possessing a certain degree of elastic deformation capability. The arc-shaped outer surface of the main body 1 can be further designed with streamlined transition surfaces to reduce edge sharpness and avoid scratching inside the pet's mouth. The brush head 4 is located at the bottom of one end of the main body 1.

[0037] Furthermore, a press-triggered structure 14 is provided at the brush head 4 position on the main body 1. A circuit board is provided inside the main body 1, and the circuit board is electrically connected to the press-triggered structure 14 and the drive unit 2 respectively. The press-triggered structure 14 is used to trigger the circuit board to control the drive unit to start after the brush head is pressed or the press-triggered structure 14 itself is pressed. By setting the press-triggered structure 14 on the main body 1 and setting the circuit board (not shown) electrically connected to the press-triggered structure 14 and the drive unit 2 inside the main body 1, the press-triggered structure 14 can detect whether the brush head 4 is pressed. The circuit board only controls the drive unit 2 to start after the brush head 4 is pressed, thereby realizing the press-triggered start method of working when in contact and stopping when removed. This avoids the phenomenon of the brush head 4 spinning without contacting the pet's teeth, effectively saving power, reducing noise, and reducing fright to the pet. At the same time, the user can operate with one hand without having to turn on an additional switch, which greatly improves the convenience and safety of operation when the pet is uncooperative during brushing.

[0038] In one embodiment, the press-triggered structure 14 is located at the brush head 4. When the pressure reaches a preset threshold, the press-triggered structure 14 generates an electrical signal and sends it to the circuit board. The circuit board may include a signal processing module, a drive control module, and a power management module. The signal processing module receives and identifies the electrical signal sent by the press-triggered structure 14. The drive control module outputs start or stop commands to the drive unit 2 based on the identification result. The power management module distributes power to each electrical component. The sensitivity of the press-triggered structure 14 can be adjusted by an adjustable resistor or software parameters on the circuit board to accommodate the pressing pressure habits of different users. A battery 5 is also provided inside the main body 1. The battery 5 is electrically connected to the circuit board to power the pet electric toothbrush. In another embodiment, a press switch is installed inside the main body and abuts against the vibration transmission structure. When the brush head is pressed, the pressure is transmitted to the press-triggered structure 14 through the drive transmission structure, triggering the press-triggered structure 14.

[0039] Specifically, in an optional embodiment, the press trigger structure 14 is a press switch, a micro switch, or a pressure sensor. The press trigger structure 14 is specifically defined as a press switch, a micro switch, or a pressure sensor. Press switches and micro switches have the advantages of simple structure, low cost, and rapid response, making them suitable for product models where cost control is critical. Pressure sensors, on the other hand, can quantitatively detect the pressing force, facilitating cooperation with the circuit board to implement more refined drive control strategies (such as adjusting the output power of the drive component 2 according to the pressing force), thereby improving the product's intelligence and user experience while ensuring trigger reliability.

[0040] Specifically, when the press-triggered structure 14 is a press switch, the press switch may include a button cap, a return spring, and a contact group. The button cap is exposed on the surface of the body 1 or located below the support structure of the brush head 4. The return spring is used to automatically reset the button cap after the pressure is removed. The contact group conducts the circuit when the button cap is pressed. When the press-triggered structure 14 is a micro switch, the micro switch may include a housing, a button, a spring, and contacts. It is small in size and can be directly mounted on the circuit board. The button can contact the brush head 4 and can be triggered when the brush head 4 is pressed and produces a small displacement. When the press-triggered structure 14 is a pressure sensor, the pressure sensor may be a resistance strain gauge, piezoelectric, or capacitive pressure sensor. Its sensing surface can be attached to the brush head 4. The analog electrical signal output by the pressure sensor is converted into a digital signal by an analog-to-digital converter on the circuit board and then used for threshold judgment. The press-triggered structure 14 can be electrically connected to the circuit board by direct soldering or wire connection. Of course, in another embodiment, the press trigger structure 14 is a control switch set on the main body. When in use, pressing the switch turns on the toothbrush and realizes the trigger structure 14 itself after being pressed.

[0041] In some embodiments, the drive transmission structure 3 can be an eccentric wheel pendulum, a transmission rod, a gear set, a belt, or a paddle. The drive transmission structure 3 is limited to an eccentric wheel pendulum, a transmission rod, a gear set, a belt, or a paddle. The eccentric wheel pendulum has a simple structure and low cost, making it suitable for generating high-frequency, low-amplitude vibrations; the transmission rod enables long-distance transmission of linear reciprocating motion, suitable for grip-type structures with a large body 1; the gear set enables changes in motion direction and speed adjustment, suitable for applications requiring precise control of the brush head 4's motion parameters; belt transmission offers advantages such as buffering, shock absorption, and smooth operation, suitable for products with high noise control requirements; and the paddle has a compact structure and sensitive response, suitable for space-constrained body 1 structures such as finger sleeves. The provision of these various transmission forms allows the product to be flexibly configured according to different drive methods, body 1 shapes, and performance requirements.

[0042] Specifically, when the drive transmission structure 3 is an eccentric wheel pendulum, the eccentric wheel pendulum may include an eccentric wheel and a pendulum mass block. The eccentric wheel is fixedly connected to the output shaft of the drive component 2, and the pendulum mass block is eccentrically disposed on the eccentric wheel. When the drive component 2 rotates, it generates centrifugal force, thereby causing vibration. This vibration is transmitted to the brush head 4 via the body 1 or directly via the brush head 4 support structure. When the drive transmission structure 3 is a transmission rod, the transmission rod may be a rigid straight rod or a flexible flexible shaft. One end of the rod is connected to the output end of the drive component 2, and the other end is connected to the brush head 4. A guide sleeve or bearing may be provided between the transmission rod and the body 1 to reduce friction. When the drive transmission structure 3 is a gear set, the gear set may include a driving gear, a driven gear, and an intermediate gear. The driving gear is connected to the drive unit 2, and the driven gear is connected to the brush head 4. The rotational speed can be increased or decreased by adjusting the gear ratio, thereby driving the brush head 4 to rotate. When the drive transmission structure 3 is a belt, the belt can be a synchronous toothed belt or a flat belt. The belt is wound around the driving pulley at the end of the drive unit 2 and the driven pulley at the end of the brush head 4. The tension of the belt can be adjusted by adjusting the center distance of the pulleys or by setting a tensioning wheel. When the drive transmission structure 3 is a paddle, the paddle can be an elastic metal sheet or a plastic sheet. One end of the paddle is fixed to the housing of the body 1 or the drive unit 2, and the other end is connected to the brush head 4. The drive unit 2 periodically moves the paddle through a cam or eccentric structure, causing the paddle to oscillate back and forth and drive the brush head 4 to move.

[0043] Furthermore, the body 1 includes a front shell 12 and a rear shell 13. The brush head 4 and the drive transmission structure 3 are installed in the front shell 12. The rear shell 13 is connected to the tail of the front shell 12, and the drive component 2 is installed in the rear shell 13. The drive transmission structure 3 passes through the tail of the front shell 12 and connects with the drive component 2. Designing the body 1 as a split structure including the front shell 12 and the rear shell 13, and installing the brush head 4 and the drive transmission structure 3 in the front shell 12 and the drive component 2 in the rear shell 13, while allowing the drive transmission structure 3 to pass through the tail of the front shell 12 and connect with the drive component 2, achieves a reasonable partitioned layout of functional modules. This allows the vibration generation area (drive component 2) and the vibration output area (brush head 4 and transmission structure) to be spatially independent yet connected by a transmission structure. This facilitates separate sealing and independent maintenance of each area. Simultaneously, the docking structure between the front shell 12 and the rear shell 13 simplifies the product assembly process and improves production efficiency and structural reliability. Based on this, in an optional embodiment, such as... Figures 6 to 10 As shown, the front end shell is detachably inserted into the end of the rear end shell. The front end shell has a clamping cavity 122. The drive transmission structure is an eccentric transmission rod 31, and the drive component is a motor. The eccentric transmission rod 31 is detachably inserted into the clamping cavity 122.

[0044] The front shell 12 can be a hollow cylindrical or conical structure, with a brush head 4 mounting hole at its front end and a through hole at its rear end for the drive transmission structure 3 to pass through. The rear shell 13 can be a hollow cylindrical or elliptical cylindrical structure, with an internal mounting cavity for accommodating the drive component 2. The front shell 12 and the rear shell 13 can be connected by snap-fit, threaded connection, plug-in fit, or ultrasonic welding. A sealing ring or sealant can be provided at the joint to enhance waterproof performance. A bearing, bushing, or sealing ring can be provided at the part of the drive transmission structure 3 that passes through the rear end of the front shell 12 to support the transmission structure and prevent liquid from seeping in through the gap. The outer surface of the rear shell 13 can be provided with a charging interface, indicator light, or function buttons. The overall shape formed after the front shell 12 and the rear shell 13 are joined can be straight, arc, or S-shaped to adapt to different grip or wearing needs.

[0045] Furthermore, a partition 112 is provided at the bottom of the finger sleeve 11. The partition 112 covers the front end shell 12 to seal the inside of the front end shell 12. The front end shell 12 has a receiving cavity 121 inside, and the brush head 4 and the drive transmission structure 3 are installed in the receiving cavity 121. By setting a partition 112 at the bottom of the finger sleeve 11 and covering the front end shell 12 to seal the inside of the front end shell 12, and forming a receiving cavity 121 inside the front end shell 12 to install the brush head 4 and the drive transmission structure 3, effective sealing and protection of the internal components of the front end shell 12 is achieved, preventing saliva, liquid or foreign objects from the pet's mouth from entering the front end shell 12 and damaging the drive transmission structure 3 or affecting its normal operation. The partition 112 also provides a supporting boundary and clearance space for the displacement of the brush head 4 under pressure and vibration, ensuring that the brush head 4 has sufficient vibration amplitude and pressing stroke, thereby ensuring cleaning effect and trigger sensitivity. At the same time, the separating effect of the partition 112 isolates the finger 6 insertion cavity 111 of the finger sleeve 11 from the receiving cavity 121 of the front end shell 12, improving the hygiene and safety of the product.

[0046] The partition 112 can be a flat plate or an arc-shaped plate structure, and its outer contour is adapted to the shape of the opening at the top of the front shell 12. The sealing connection between the partition 112 and the front shell 12 can be achieved by adhesive bonding.

[0047] Furthermore, a massage structure 7 (not shown) is provided around the outer circumference of the brush head 4. By providing the massage structure 7 around the outer circumference of the brush head 4, while the bristles in the central area of ​​the brush head 4 clean the pet's teeth, the massage structure 7 can contact the pet's gums and apply a massage effect, thereby cleaning the gum line, promoting blood circulation in the gums, and relieving gum inflammation, thus improving the pet's oral health and user comfort. The massage structure 7 is located around the outer circumference of the brush head 4, so that it can naturally conform to the junction of teeth and gums when the brush head 4 is inserted into the pet's mouth, achieving simultaneous cleaning and massage without additional adjustments by the user, simplifying the operation process, and enhancing the product's functional integration and ease of use.

[0048] The massage structure 7 can be integrally formed with the brush head 4, or installed on the outer periphery of the brush head 4 by means of snap-fit, bonding, interference fit, etc.; the color of the massage structure 7 can be different from the bristles so that the user can observe its position in the pet's mouth.

[0049] Specifically, the brush head 4 is made of soft rubber bristles or nylon bristles, and the massage structure 7 is made of soft rubber protrusions, soft rubber bristles, or a ring-shaped soft rubber lip. The soft rubber bristles are soft and elastic, causing minimal irritation to the pet's gums, making them suitable for pets with sensitive gums or those brushing for the first time. The nylon bristles have moderate hardness and strong abrasion resistance, providing a more significant cleaning effect, making them suitable for pets with severe plaque buildup. The soft rubber protrusions provide point-press massage, the soft rubber bristles can penetrate deep into the gingival sulcus for cleaning and massage, and the ring-shaped soft rubber lip provides continuous circular massage.

[0050] The soft rubber bristles can be made of silicone, TPE (thermoplastic elastomer), or TPU (thermoplastic polyurethane); the nylon bristles can be made of PA6, PA66, or PA612 nylon; the soft rubber protrusions can be hemispherical, conical, cylindrical, or corrugated; the annular soft rubber lip can be a continuous ring or an intermittent arc, and its cross-sectional shape can be circular, elliptical, or rectangular. The inner diameter of the lip can be tightly fitted with the outer diameter of the brush head 4; the bristles and massage structure 7 can be integrally molded with the base of the brush head 4 through a two-color injection molding process, or molded separately and then assembled onto the base.

[0051] In another optional embodiment, a hard bristle 41 is provided at the bottom of the end of the brush head away from the main body, and the massage structure 7 consists of soft massage bristles 71 arranged around the hard bristles 41 and a massage protrusion 72 arranged at the top of the end of the brush head away from the main body. In use, both the soft massage bristles 71 and the massage protrusion 72 can massage the pet's mouth.

[0052] Specifically, the driving component 2 is a vibration driving component, a rotation driving component, or a sweeping driving component, and the driving transmission structure 3 is a vibration transmission structure, a rotation transmission structure, or a sweeping transmission structure. The vibration drive combined with the vibration transmission can achieve high-frequency micro-amplitude ultrasonic or sonic cleaning, the rotation drive combined with the rotation transmission can achieve continuous rotational polishing cleaning of the brush head 4, and the sweeping drive combined with the sweeping transmission can achieve reciprocating oscillation sweeping cleaning of the brush head 4, covering the mainstream electric toothbrush cleaning modes, allowing the product to select the optimal cleaning method according to the pet's dental condition and cleaning needs.

[0053] When the driving component 2 is a vibration driving component 2, it can be an ultrasonic transducer, a micro high-frequency vibration motor, or an eccentric wheel motor. The vibration transmission structure can be a rigid transmission rod, a flexible shaft, or a direct contact transmission block. The vibration transmission structure directly transmits the high-frequency vibration generated by the vibration driving component 2 to the brush head 4, causing the bristles to generate a high-frequency vibration. When the driving component 2 is a rotary driving component, it can be a DC micro motor or a stepper motor. The rotary transmission structure can be a gear set, a worm gear mechanism, or a belt drive mechanism, transmitting the continuous rotational motion of the rotary driving component to the brush head 4, causing the brush head 4 to rotate rapidly. When the driving component 2 is a sweeping driving component, it can be a reciprocating oscillating motor or an electromagnetic driver. The sweeping transmission structure can be a crank-slider mechanism, a cam mechanism, or a shift fork mechanism, transmitting the reciprocating motion of the sweeping driving component to the brush head 4, causing the brush head 4 to oscillate back and forth within a preset angle range. The installation positions of the driving component 2 and the drive transmission structure 3 can be isolated from the body 1 by shock-absorbing pads or shock-absorbing brackets to reduce the vibration and noise transmitted to the body 1. In some alternative embodiments, such as Figure 11 and Figure 12 As shown, brush head 4 can be configured as a dual brush head structure, that is, with two sets of bristles to improve cleaning efficiency.

[0054] In some embodiments, the brush head 4 on the main body 1 is further provided with a bubble generating structure 8, a spraying structure 9, a sterilization structure (not shown), or a lighting structure (not shown). By providing a bubble generating structure 8, a spraying structure 9, a sterilization structure, or a lighting structure on the brush head 4 on the main body 1, multiple auxiliary function modules are further integrated on top of the basic electric cleaning function. The bubble generating structure 8 can work with toothpaste or dental cleaning solution to generate rich bubbles to enhance the cleaning effect and fun. The spraying structure 9 can directly spray cleaning solution into the pet's mouth to improve cleaning efficiency. The sterilization structure can sterilize the brush head 4 or the pet's mouth to inhibit bacterial growth. The lighting structure can illuminate the inside of the pet's mouth so that the user can observe the condition of the teeth and the cleaning effect. The above-mentioned multi-functional integration upgrades the product from a single cleaning tool to a comprehensive pet oral care system, significantly improving the product's added value, ease of use, and comprehensive care.

[0055] Specifically, the bubble generating structure 8 may include a microporous foaming sheet, ultrasonic atomizing sheet, or Venturi tube structure disposed inside the brush head 4 or at the front end of the body 1. The bubble generating structure 8 is connected to a liquid storage chamber disposed inside the body 1 via an air tube or a liquid tube. The liquid storage chamber may be pre-filled with dental cleaning solution or water. When the drive unit 2 or the independent air pump 81 is working, bubbles are generated and escape from the holes of the brush head 4. The liquid spraying structure 9 may include a micro liquid pump 81, a nozzle, and a liquid storage tank. The nozzle is disposed near the brush head 4 or at the root of the bristles. The micro liquid pump 81 sprays the liquid in the liquid storage tank through the nozzle in the form of a mist or liquid column. The liquid storage tank may be detachable and snapped onto the tail of the body 1. The sterilization structure may include an ultraviolet LED lamp or an ozone generator. The ultraviolet LED lamp may be disposed on the back of the brush head 4 or at the front end of the body 1 to irradiate the bristles when the brush head 4 is not in use. For sterilization, or for irradiating the pet's mouth during use to assist in sterilization, the wavelength of the ultraviolet LED lamp can be set to 200nm to 280nm; the lighting structure can include white LED lamps or blue LED lamps. White LED lamps are used to illuminate the inside of the pet's mouth for easy observation, while blue LED lamps have both lighting and auxiliary sterilization functions. The LED lamps can be set at the center of the brush head 4, the outer periphery of the brush head 4, or the front end of the body 1, and their light can be evenly distributed through light guide pillars or light guide plates; the bubble generating structure 8, the liquid spraying structure 9, the sterilization structure, and the lighting structure can be controlled independently, or linked together through a circuit board. For example, the lighting structure automatically turns on when the pressure trigger structure 14 detects pressure, and the sterilization structure turns on after a delay after the drive component 2 stops working. The specific settings and controls can all adopt conventional technical means, which will not be elaborated here.

[0056] Specifically, in an optional embodiment, the bubble generating structure 8 includes an air pump 81 and an air guide pipe 82. The air pump 81 and the air guide pipe 82 are disposed in the main body. The air pump 81 is connected to the air guide pipe 82. The air guide pipe 82 is connected to the hollow eccentric transmission rod 31 of the drive member at the tail end of the drive member. An air outlet 42 is provided at the brush head. The eccentric transmission rod 31 is connected to the air outlet 42 through the insertion cavity 122. After the air pump 81 compresses the air, it is delivered to the hollow channel of the hollow eccentric transmission rod 31 through the air guide pipe 82. The brush head is provided with an air jet nozzle. When cleaning and brushing the pet's teeth, the compressed gas is ejected from the air jet nozzle and mixes thoroughly with toothpaste and water to form bubbles.

[0057] Specifically, in an optional embodiment, the spray structure 9 includes a liquid pump 81, a liquid guide tube 82, and a liquid storage tank 83. The liquid pump 81, liquid storage tank 83, and liquid guide tube 82 are disposed in the main body. The liquid storage tank 83 is connected to the liquid pump 81, and the liquid pump 81 is connected to the liquid guide tube 82. The liquid guide tube 82 is connected to the hollow eccentric transmission rod 31 of the drive component at the tail end of the drive component. A liquid outlet is provided at the brush head, and the eccentric transmission rod 31 communicates with the liquid outlet through the insertion cavity 122. The built-in liquid storage tank 83 is used to store clean water or prepared toothpaste cleaning solution. The micro liquid pump 81 pressurizes the liquid in the tank, and the pressurized liquid is transported to the hollow eccentric transmission rod 31 through the liquid guide tube 82. The liquid is finally transported to the liquid outlet next to the air jet nozzle of the brush head. When brushing, the liquid continuously flows out from the liquid outlet and mixes instantly with the high-pressure airflow sprayed from the air jet nozzle, fully emulsifying and foaming to improve the oral cleaning effect for pets.
