[0002] A toothbrush is a cleaning product, a handle-type brush that is used to add toothpaste to the brush and then repeatedly brush various parts of the teeth to maintain oral hygiene. As an important daily necessity, toothbrushes also play an important role in people's lives. However, during the brushing process, water often flows down the toothbrush handle to the user's hands or drips onto the ground, which not only reduces the user experience, but also limits the user to brushing their teeth in front of the sink, which cannot adapt to the fast-paced life of modern people. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect of the toothbrush in the prior art that water is easy to drip during the brushing process, thereby providing a toothbrush that is not easy to cause water to drip onto the hands and does not limit the brushing position.

[0012] Furthermore, a water-holding edge surrounding the one-way water flow component is provided on the brush handle in the circumferential direction.

[0013] Furthermore, the brush handle includes a holding portion and a cover body detachably connected to the holding portion, the cover body has a first state in which it is detachably connected to the holding portion and a second state in which it is sleeved on the brush head. When the cover body is in the first state, a water storage cavity is formed between the cover body and the holding portion, and a water storage edge is formed on the cover body.

[0014] Furthermore, when the cover body is in the second state, the edge of the cover body and the holding portion are interference fit.

[0015] Furthermore, an external thread is provided at the bottom of the holding portion, an internal thread suitable for matching with the external thread is provided on the inner peripheral wall of the cover body, the internal thread is spaced apart from the edge of the cover body, and the water-containing edge is formed between the edge of the cover body and the internal thread.

[0016] Furthermore, the toothbrush also includes a folding mechanism, and the folding mechanism includes:

[0017] A backing plate connected to an end of the holding portion away from the cover body, and a receiving cavity is formed on the backing plate;

[0018] A rotating part, which is hinged to the backing plate, and a brush head is formed on the rotating part;

[0019] An intermediate rod, one end of which is hinged to a side of the rotating part away from the backing plate;

[0020] A wrench, which is hinged to the backing plate, and the other end of the intermediate rod is hinged to the wrench;

[0021] A torsion spring, one end of which is embedded in the brush handle, and the other end of which acts on the wrench position, and the torsion spring is suitable for providing a biasing force for the wrench to rotate toward the backing plate;

[0022] The toothbrush has a folded-in state in which the wrench rotates forward toward the brush handle under the drive of external force and drives the brush head to enter the accommodating cavity, and a folded-out state in which the wrench rotates reversely relative to the brush handle under the drive of external force and drives the brush head to rotate out of the accommodating cavity.

[0023] Furthermore, the toothbrush also includes a disinfection component disposed in the accommodating cavity, and when the toothbrush is in the folded state, the bristles of the toothbrush face the disinfection component.

[0024] Furthermore, the switch of the disinfection component is arranged corresponding to the rotating part of the toothbrush.

[0025] Furthermore, the disinfection component is an ultraviolet disinfection lamp, the lamp board of the ultraviolet disinfection lamp is fixedly arranged in the accommodating cavity and arranged opposite to the bristles of the toothbrush, the holding part is hollow and connected to the accommodating cavity, the power supply element and circuit board of the disinfection component are arranged in the holding part and are communicatively connected to the lamp board.

[0026] The present invention has the following advantages:

[0027] 1. It can be seen from the above technical solution that the toothbrush of the present invention is provided with a one-way water flow component and a water storage chamber connected to the one-way water flow component on the brush handle. Since the one-way water flow component can only supply water to the water storage chamber in one direction, the water generated by the user during the brushing process can only flow into the water storage chamber through the one-way water flow component and cannot flow out through the one-way water flow component. Therefore, the toothbrush of the present application can not only collect the water generated during the brushing process, avoiding the extra burden of the user to clean the floor due to the dripping of water; but also prevent the water in the water storage chamber from flowing out by virtue of the one-way water flow characteristic of the one-way water flow component, ensuring that the water in the water storage chamber will not flow out when the user brushes his teeth at various angles. Therefore, the toothbrush of the present invention overcomes the defect of the toothbrush in the prior art that water is easy to drip during the brushing process, so that the user does not have to brush his teeth in front of the washbasin and it is not easy for water to drip onto the ground, which helps to adapt to the fast-paced life of modern people.

[0028] 2. The one-way water flow assembly includes a through hole, a stopper, an elastic member and a blocking member. The through hole is provided on the handle wall of the brush handle. The stopper is fixedly arranged in the through hole. A connecting through hole is provided on the stopper. The blocking member is installed in the through hole and can block the end of the through hole close to the brush head under the push of the elastic member. The stopper is bonded to the through hole. When the user uses a toothbrush to brush his teeth, the water flowing down the brush head can enter the through hole when flowing through the one-way water flow assembly and exert pressure on the blocking member by its own gravity. The elastic member connected to the blocking member can be compressed, so that a gap is generated between the blocking member and the hole wall of the through hole, allowing the water entering the through hole to enter the water storage chamber through the gap between the blocking member and the hole wall of the through hole. When the water enters the water storage chamber, the elastic member can lose the external force and return to its original state through its own elastic restoring force, pushing the blocking member to block the through hole close to the end of the brush head, thereby preventing the water in the water storage chamber from flowing out through the one-way water flow assembly. Therefore, when the user changes the angle of the brush handle during brushing, the elastic member can always apply force to the blocking member in the direction close to the brush head, and avoid the formation of a gap between the blocking member and the hole wall of the through hole, ensuring that the user can flexibly use the toothbrush to clean the oral cavity at multiple angles without water flowing out of the water storage cavity.

[0029] 3. A water-holding edge surrounding the one-way water flow assembly is provided on the circumferential edge of the brush handle. The water-holding edge can collect the water flowing down during brushing between the cover body and the gripping portion, and then discharge it into the water storage chamber through the one-way water flow assembly, which can further ensure that all the water flowing down during brushing can be collected. Preferably, eight one-way water flow assemblies are provided on the brush handle. The eight one-way water flow assemblies are arranged at equal central angles. After many experiments, the applicant has confirmed that when eight one-way water flow assemblies are provided on the circumferential edge of the brush handle, it can ensure that when the user swings the brush handle to various angles, there is a one-way water flow assembly at the lowest point between the water-holding edge and the gripping portion or near the lowest point. The water between the water-holding edge and the gripping portion can smoothly enter the water storage chamber through the one-way water flow assembly under the action of gravity. At the same time, the manufacturing cost of the toothbrush 1 will not be excessively increased.

[0030] 4. The brush head is connected to the brush handle through a folding mechanism. A foldable toothbrush can be convenient for users to carry, which helps to improve user experience. The folding mechanism includes a pad, a rotating part, an intermediate rod, a wrench and a torsion spring. Among them, the pad is arranged on the end of the holding part away from the cover body. A receiving cavity is formed on the pad. The rotating part is hinged to the pad. The brush head is formed on the rotating part. One end of the intermediate rod is hinged to the side of the rotating part away from the pad. The wrench is hinged to the pad and the other end of the intermediate rod is hinged to the wrench. One end of the torsion spring is embedded in the brush handle. The other end of the torsion spring acts on the wrench position. The torsion spring is suitable for providing a biasing force for the wrench to rotate toward the pad. The toothbrush has a folded-in state when the wrench is driven by an external force to rotate forward toward the brush handle and drive the brush head to enter the receiving cavity, and a folded-out state when the wrench is reversed relative to the brush handle under the drive of an external force and drives the brush head to rotate out of the receiving cavity. When the brush head is in the folded-in state, the thumb moves the wrench, and the brush head rotates due to the eccentric force to reach the folded-out intermediate state. The thumb releases the wrench, and the brush head folds out and rotates under the action of the torsion spring to reach the folded-out state. Thereby, the brush head is opened relative to the brush handle. The toothbrush has a folded-in state when the wrench is driven by an external force to rotate forward toward the brush handle and drive the brush head to enter the accommodating cavity, and a folded-out state when the wrench is driven by an external force to reverse relative to the brush handle and drive the brush head to rotate out of the accommodating cavity.

[0031] With the above-mentioned arrangement, the user only needs to place a finger, such as a thumb, on the wrench position to open and close the brush head relative to the brush handle, thereby avoiding contamination of the brush head when the hand acts on the brush head to perform a bend operation.

[0032] 5. The toothbrush also includes a disinfection component arranged in the accommodating cavity. When the toothbrush is in the first state and folded, the bristles of the toothbrush face the disinfection component. Therefore, when the toothbrush is in an idle state, the brush head is folded onto the brush handle, and the disinfection component can disinfect the brush head of the toothbrush to prevent bacteria from growing on the bristles. The switch of the disinfection component is arranged on the brush handle or folding mechanism of the toothbrush and corresponds to the rotating part of the toothbrush. This enables the rotating part to trigger the switch of the disinfection component whenever the toothbrush is folded onto the brush handle, so that the disinfection component is turned on and the toothbrush is disinfected. There is no need for the user to operate separately, which avoids the growth of bacteria on the toothbrush due to untimely disinfection. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0050] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0052] Figure 1 A toothbrush according to an embodiment of the present invention is shown, wherein the cover of the toothbrush is in a first state. Figure 2 for Figure 1 The handle and cover of the toothbrush are shown, and the cover is in the second state. Figure 3 for Figure 2 A in the figure is enlarged. Figure 1 , Figure 2 and Figure 3 As shown, this embodiment relates to a toothbrush 100, including a brush handle, a brush head 2, a one-way water flow component 3 and a water storage chamber 4. The brush head 2 is arranged on the brush handle. The one-way water flow component 3 is arranged on the brush handle. The water storage chamber 4 is formed in the brush handle and is connected to the one-way water flow component 3, and is suitable for receiving water input by the one-way water flow component 3.

[0053] It can be seen from the above technical solution that the toothbrush 100 of this embodiment is provided with a one-way water flow component 3 and a water storage chamber 4 connected to the one-way water flow component 3 on the brush handle. Since the one-way water flow component 3 can only supply water to the water storage chamber 4 in one direction, the water generated by the user during the brushing process can be collected by the water storage chamber 4, avoiding the additional burden of cleaning the floor for the user; and the one-way permeability of the one-way water flow component 3 is used to avoid the outflow of water in the water storage chamber 4, ensuring that the water in the water storage chamber 4 will not flow out when the user brushes his teeth at various angles. Therefore, the toothbrush 100 of this embodiment overcomes the defect of the toothbrush in the prior art that water is easy to drip during the brushing process, so that the user does not have to brush his teeth in front of the washbasin and it is not easy for water to drip onto the ground, allowing the brushing operation to be performed in more scenarios, which helps to adapt to the fast-paced life of modern people.

[0054] The one-way water flow component 3 is preferably, but not limited to, a spring-type one-way valve, a gravity-type one-way valve or a plastic diaphragm one-way valve. For example, in the present embodiment, the one-way water flow component 3 includes a through hole 31, a stopper 32, an elastic member 33 and a blocking member 34. The through hole 31 is provided on the handle wall of the brush handle. The stopper 32 is fixedly arranged in the through hole 31. The stopper 32 is provided with a connecting through hole 31. The blocking member 34 is installed in the through hole 31, and can block one end of the through hole 31 close to the brush head 2 under the push of the elastic member 33. The stopper 32 and the through hole 31 are preferably, but not limited to, bonded, clamped or detachably connected by fasteners.

[0055] Specifically, when a user uses the toothbrush 100 of this embodiment to brush teeth, water flowing down the brush head 2 can enter the through hole 31 when flowing through the one-way water flow assembly 3 and apply pressure to the blocking member 34 by its own gravity. The elastic member 33 connected to the blocking member 34 can be compressed, so that a gap is generated between the blocking member 34 and the hole wall of the through hole 31, allowing the water entering the through hole 31 to enter the water storage chamber 4 through the gap between the blocking member 34 and the hole wall of the through hole 31. After the water enters the water storage chamber 4, the elastic member 33 can lose the external force and restore its original state through its own elastic restoring force, pushing the blocking member 34 to block the end of the through hole 31 close to the brush head 2, thereby preventing the water in the water storage chamber 4 from flowing out through the one-way water flow assembly 3. Therefore, when the user changes the angle of the brush handle during brushing, the elastic member 33 can always apply a force to the blocking member 34 in the direction close to the brush head 2, and avoid the generation of a gap between the blocking member 34 and the hole wall of the through hole 31. It ensures that the user can flexibly use the toothbrush 100 to clean the oral cavity from multiple angles without water flowing out of the water storage chamber 4. The elastic member 33 is preferably, but not limited to, a spring or an elastic plug. For example, in the present embodiment, the diameter of the steel ball is selected to be 2 mm. The elastic member 33 is selected to be a spring, the material of which is spring steel, and the outer diameter of the spring is 2 mm. Those skilled in the art can design the wire diameter and effective number of turns of the spring according to the diameter and weight of the steel ball to ensure that the elastic member 33 can be compressed by the sealing member 34 when there is water on the sealing member 34, thereby allowing the water on the brush head to enter the water storage chamber 4; and can rely on its own elastic restoring force to push the sealing member 34 to seal the through hole 31 when there is no water on the sealing member 34.

[0056] The one-way water flow member can be arranged on the side wall of the brush handle, or can be arranged at the connection between the brush head 2 and the brush handle. Preferably, in this embodiment, the toothbrush 100 also includes a flange 11 protruding from the brush handle in the circumferential direction, and the one-way water flow assembly 33 is formed at the junction of the flange 11 and the brush handle. This allows the water flowing along the surface of the brush handle to flow directly into the through hole 31. At the same time, the flange 11 can also play a certain role in containing water, further reducing the risk of water dripping. Preferably, a water-containing extension 16 surrounding the one-way water flow assembly 3 is provided on the brush handle in the circumferential direction. The water-containing extension 16 can collect the water flowing down during brushing between the cover body 15 and the gripping portion 14, and then discharge it into the water storage chamber 4 through the one-way water flow assembly 3, which can further ensure that the water flowing down during brushing can be collected. There is no excessive restriction on the number of one-way water flow assemblies 3. For example, in this embodiment, eight one-way water flow assemblies 3 are preferably arranged on the brush handle. The eight one-way water flow assemblies 3 are arranged at equal central angles. The applicant has confirmed through many experiments that when eight one-way water-flow components 3 are arranged on the circumference of the brush handle, it can ensure that when the user swings the brush handle to various angles, there are one-way water-flow components 3 at or near the lowest point between the water-holding edge 16 and the gripping portion 14. Water between the water-holding edge 16 and the gripping portion 14 can smoothly pass through the one-way water-flow components 3 into the water storage chamber 4 under the action of gravity. At the same time, the manufacturing cost of the toothbrush 100 will not be excessively increased.

[0057] In order to facilitate the sealing between the through hole 31 and the blocking member 34, the through hole 31 is preferably a cylindrical hole. The blocking member 34 is preferably a rotating body, such as a bullet-shaped, conical or spherical one. When the blocking member 34 is set as a rotating body, it is only necessary to confirm that the maximum diameter of the blocking member 34 is greater than the maximum inner diameter of the through hole 31 on the side facing the brush head 2 to ensure the sealing between the blocking member 34 and the through hole 31. For example, in the present embodiment, the blocking member 34 is a steel ball, and the diameter of the steel ball is greater than the inner diameter of the end of the through hole 31 close to the brush head 2, and is smaller than the inner diameter of the end of the through hole 31 away from the brush head 2. This allows the steel ball to be inserted from the end of the through hole 31 away from the brush head 2, and to block the end of the through hole 31 close to the brush head 2 under the support of the elastic member 33.

[0058] In this embodiment, the brush handle preferably includes a gripping portion 14 and a cover 15 detachably connected to the gripping portion 14. The cover 15 has a first state in which it is detachably connected to the gripping portion 14 and a second state in which it is sleeved on the brush head 2. The flange 11 is formed at the bottom end of the gripping portion 14. When the cover 15 is in the first state, a water storage chamber 4 is formed between the cover 15 and the gripping portion 14. This allows a cover 15 to not only play a role in storing water, but also to be covered on the brush head 2 of the toothbrush 100 when the toothbrush 100 is not in use, saving the cost of the toothbrush 100 and making the structure of the toothbrush 100 more compact. Early introduction can not only prevent external bacteria from contaminating the brush head 2, but also prevent ultraviolet rays from leaking and causing damage to the human eye or reducing the sterilization efficiency when the disinfection component 9 is selected as an ultraviolet disinfection lamp.

[0059] The detachable connection between the cover body 15 and the handle 14 can be selected as riveting, clamping or threading. However, since the cover body 15 needs to hold water when it is in the first state, the connection strength between the cover body 15 and the handle 14 is relatively high. When the cover body 15 is in the first state, the cover body 15 and the handle 14 are preferably connected by threads. When the cover body is in the second state, the connection strength between the cover body 15 and the handle 14 is less required. Therefore, when the cover body 15 is in the second state, the cover body 15 and the handle 14 are preferably clamped. For example, in the case of Figure 1 In the illustrated embodiment, the edge of the cover body 15 is configured to be interference fit with the handle 14. An external thread 17 is provided on the bottom of the handle 14, and an internal thread 18 suitable for threaded connection with the external thread 17 is provided on the inside of the cover body 15. The internal thread 18 is preferably configured to be spaced from the edge of the cover body 15. This can not only prevent the internal thread 18 on the cover body 15 from being damaged when the cover body 15 and the handle 14 are clamped, but also form a water-holding edge 16 surrounding the handle 14 at the connection between the cover body 15 and the handle 14.

[0060] In this embodiment, if Figure 4 and Figure 5 As shown, the brush head 2 is preferably connected to the brush handle through a folding mechanism. The foldable toothbrush 100 can be convenient for users to carry, which helps to improve user experience. Preferably, the folding mechanism includes a pad 12, a rotating part 5, an intermediate rod 6, a wrench 7 and a torsion spring 8. Among them, the pad 12 is arranged at the end of the holding part 14 away from the cover body 15. A accommodating cavity 13 is formed on the pad 12. The rotating part 5 is hinged to the pad 12. The brush head 2 is formed on the rotating part 5. One end of the intermediate rod 6 is hinged to the side of the rotating part 5 away from the pad 12. The wrench 7 is hinged to the pad 12. As shown Figure 6 and Figure 7As shown, the other end of the intermediate rod 6 is hinged on the wrench 7. One end of the torsion spring 8 is embedded in the brush handle. The other end of the torsion spring 8 acts on the wrench 7. The torsion spring 8 is suitable for providing a biasing force for the wrench 7 to rotate toward the backing plate 12. The toothbrush 100 has a folded-in state when the wrench 7 is driven by an external force to rotate forward toward the brush handle and drive the brush head 2 to enter the accommodating chamber 13, and a folded-out state when the wrench 7 is driven by an external force to rotate relative to the brush handle and drive the brush head 2 to rotate out of the accommodating chamber 13.

[0061] Specifically, when the brush head 2 is in the folded-in state, the thumb moves the wrench 7, and the brush head 2 rotates due to the eccentric force to reach the folded-out intermediate state (see FIG. Fig. 9 ), release the wrench 7 with your thumb, and under the action of the torsion spring 8, the brush head 2 is folded out and rotated to reach the folded-out state of the brush head 2 (see Figure 8 ). Thus, the brush head 2 is opened relative to the brush handle. The toothbrush 100 has a folded-in state in which the wrench 7 is driven by an external force to rotate forward toward the brush handle and drive the brush head 2 to enter the accommodating cavity 13, and a folded-out state in which the wrench 7 is driven by an external force to reverse relative to the brush handle and drive the brush head 2 to rotate out of the accommodating cavity 13. In this embodiment, the forward rotation direction is clockwise, and the reverse rotation direction is counterclockwise.

[0062] When the brush head 2 is folded onto the brush handle 1, the wrench 7 can be automatically reset by setting the torsion spring 8. At the same time, due to the action of the torsion spring 8, the intermediate rod 6 can stabilize the brush head 2 in the accommodating cavity 13, thereby preventing the brush head 2 from shaking. At the same time, when the brush head 2 is opened relative to the brush handle, the torsion spring 8 drives the wrench 7 to be tightly attached to the accommodating cavity 13, so that the stable wrench 7 can achieve stable support for the intermediate rod 6 itself, and further enable the intermediate rod 6 to stably support the rotating part 5, thereby improving the stability of the brush head 23 during use.

[0063] In this embodiment, through the combination of the rotating part 5, the torsion spring 8, and the wrench 7, when the brush head 2 is in the folded-out state, the wrench 7 is bent, and the wrench 7 pulls the intermediate rod 6 to move. Since the intermediate rod 6 acts on the eccentric part of the rotating part 5, the brush head 2 can be rotated by the eccentric force to reach the folded-in intermediate state (see Fig.10 ), release the wrench 7 with your thumb, and under the action of the torsion spring 8, the torsion spring 8 can drive the wrench 7 to reset toward the accommodating cavity 13, and the brush head 2 folds in and rotates to reach the folded-in state of the brush head 2 (see Fig.11 and Fig.12 ).

[0064] With the above-mentioned arrangement, the user only needs to place a finger, such as a thumb, on the position of the wrench 7 to open and close the brush head 2 relative to the brush handle, thereby avoiding contamination of the brush head 2 when the hand acts on the brush head 2 to perform a prying operation.

[0065] In the present embodiment, the toothbrush 100 further includes a disinfection component 9 disposed in the accommodating cavity 13. When the toothbrush 100 is in the first state and folded into the state, the bristles of the toothbrush 100 face the disinfection component 9. Therefore, when the toothbrush is in an idle state, the brush head 2 is folded into the brush handle, and the disinfection component 9 can disinfect the brush head 2 of the toothbrush 100 to prevent bacteria from growing on the bristles. The switch 91 of the disinfection component 9 can be disposed on the brush handle or folding mechanism of the toothbrush 100. For example, in the present embodiment, the switch 91 of the disinfection component 9 is disposed corresponding to the rotating part 5 of the toothbrush 100.
