Description
Technical Field
[0001] This utility model relates to a pet toothbrush with multi-speed rotation and paste supply functions, belonging to the field of pet toothbrush technology. Background Technology
[0002] Currently, common pet toothbrushes on the market mainly include traditional straight-handle toothbrushes, replaceable-head toothbrushes, and electric rotating-head toothbrushes. Traditional straight-handle toothbrushes typically consist of a handle and a fixed brush head. The brush head angle is not adjustable, allowing cleaning only in a fixed direction. When cleaning the inside of a pet's teeth or back teeth, due to the narrow oral cavity and limited angle, users often need to change their holding posture or forcibly adjust the pet's head, resulting in low cleaning efficiency and potential discomfort for the pet. Replaceable-head toothbrushes often use threaded or snap-fit connections for easy brush head replacement, but the brush head is fixed in position after connection and cannot be adjusted or rotated. Forcibly changing the angle can lead to loosening or damage to the connection. Electric rotating-head toothbrushes rely on a motor to rotate the brush head for cleaning. However, these products have a complex structure, high cost, and stringent sealing requirements, making them unsuitable for everyday household use.
[0003] Therefore, there is an urgent need for a pet toothbrush that is simple in structure, adjustable in angle, and flexible in operation. Utility Model Content
[0004] To address the aforementioned issues, this invention provides a pet toothbrush with multi-level rotation and balm dispensing functions. This pet toothbrush with multi-level rotation and balm dispensing functions can adjust the angle of the brush head, flexibly change the cleaning direction according to the pet's oral cavity shape, and can position the adjusted angle, thereby improving cleaning efficiency and user experience.
[0005] This utility model is achieved through the following technical solution: This utility model provides a pet toothbrush with multi-speed rotation and paste dispensing functions, including: The brush handle body has a paste storage cavity inside. A brush head holder is connected to the brush handle body. The brush head holder is provided with slots that are distributed in a ring on the surface of the brush head holder. The brush head has a first protrusion on one side, which engages with the slot. A connecting shaft is embedded in the brush head, and one end of the connecting shaft is connected to the brush head seat.
[0006] In one embodiment of this invention, the card slots are multiple, and the included angle between any two adjacent card slots is 60°, thereby enabling six adjustable positions.
[0007] In one embodiment of this utility model, the connecting shaft includes a stepped shaft, a central channel, and a second groove. The central channel passes through the connecting shaft, and the second groove is disposed on both sides of the stepped shaft. The stepped shaft abuts against the brush head.
[0008] In one embodiment of this utility model, the connecting shaft includes a first snap-fit and a cream outlet, the cream outlet being located on one side of the central channel, and the first snap-fit abutting against the brush head. This securely connects the connecting shaft to the brush head.
[0009] In one embodiment of this utility model, the brush head includes a stepped hole and a central hole, the connecting shaft is embedded in the stepped hole and the central hole, and the stepped shaft abuts against the stepped hole.
[0010] In one embodiment of this utility model, the stepped hole includes a third boss, which engages with the second groove.
[0011] In one embodiment of this utility model, the brush head seat includes a first boss and a first hole, the first hole penetrates the brush head seat and communicates with the central channel, and the first boss is connected to the connecting shaft.
[0012] In one embodiment of this utility model, the brush head holder includes a second buckle, which abuts against the stepped hole.
[0013] In one embodiment of this utility model, the brush handle body is provided with a delivery pipe, and the two ends of the delivery pipe are respectively connected to the paste storage cavity and the first hole.
[0014] In one embodiment of this utility model, a toothpaste dispensing cap is included, which is detachably connected to the brush handle body. By removing the dispensing cap, toothpaste can be added to the toothpaste reservoir and the reservoir can be sealed.
[0015] Beneficial effects This utility model provides a pet toothbrush with multi-level rotation and toothpaste dispensing functions, comprising a brush head and a brush head base. A first protrusion is provided on one side of the brush head, and a slot is provided on one side of the brush head base. The first protrusion engages with the slot to position and lock the brush head. The slot has six positions, allowing users to adjust the engagement position of the first protrusion and the slot according to their needs, enabling flexible switching of the brush head angle. Users can adjust the angle at any time according to the cleaning area (such as incisors, canines, molars, and the inner surfaces of teeth). For example, a vertical position can be used to clean the surface of incisors, while an angled position can be used to clean deeper into the oral cavity or the inner surfaces of teeth, achieving a thorough cleaning effect with no blind spots and significantly improving cleaning coverage. Furthermore, the engagement of the slot and the first protrusion ensures immediate locking after angle adjustment, resulting in a stable and reliable structure that prevents accidental rotation or loosening during brushing, ensuring the safety of both the pet and the user. The flexible angle adjustment reduces the difficulty of operation within the pet's mouth, minimizes traction and irritation to the pet's oral tissues, and improves the pet's cooperation and comfort during brushing.
[0016] This pet toothbrush achieves continuous toothpaste supply through its structure, which includes a toothpaste reservoir, delivery pipes, a central channel, and a first hole. This eliminates the need to frequently remove the toothbrush from the pet's mouth, significantly simplifying the brushing process and making it more continuous and efficient. The toothpaste is delivered entirely within a sealed pipe, preventing exposure to the external environment, reducing the possibility of contamination, and meeting the hygiene requirements for pet care.

[0029] The working principle of this utility model is as follows: In use, first remove the toothpaste cap 6 and inject pet toothpaste into the toothpaste reservoir 2. Then, insert the cap 6 into the brush handle body 1. The user can squeeze the toothpaste out of the reservoir 2 by pressing the squeezing mechanism 12. The toothpaste enters the first hole 44 of the brush head seat 4 through the delivery pipe 13, then enters the central channel 33 in the connecting shaft 3 through the first hole 44, and is squeezed onto the brush head 5 through the toothpaste outlet 34. When the first protrusion 52 is inserted into the slot 42 on the same axis as the third protrusion 535, the brush head seat 4 and the brush head 5 are in a vertical position, suitable for cleaning the pet's front teeth. When the user rotates the brush head 5 forcefully, the first protrusion 52 rotates into other slots 42 in sequence (60°, 120°, 180°, etc.), achieving switching between different tilt states, suitable for cleaning the molar area or inner teeth deep in the pet's mouth, thus achieving a zero-dead-angle cleaning effect and significantly improving cleaning coverage.
