Technical Field

[0001] The utility model relates to the technical field of daily cleaning products, in particular to a cleaning toothbrush handle and a toothbrush. Background Art

[0002] Existing toothbrushes are basically made of plastic, and the entire handle and toothbrush head are formed in one piece. When they need to be replaced, you can only replace them with a brand new toothbrush. According to dentists' recommendations, a new toothbrush should be replaced every 3 months. However, after the toothbrush is discarded, a lot of non-degradable domestic waste is generated, causing environmental pollution.

[0003] Furthermore, electric toothbrushes or brittle toothbrushes need further protection to prevent the toothbrushes from falling to the ground and causing functional loss or structural damage. The existing technology generally wraps a layer of plastic on the outer surface of the toothbrush handle as a whole, or uses a tough metal material to wrap the functional parts. However, plastic materials are easy to harbor dirt and dirt, difficult to keep clean in a humid environment, and easy to rot. The overall wrapping method affects the replacement of toothbrushes and is not environmentally friendly. Metal materials are easy to rust in a humid environment, have a short service life, and have a poor feel. Utility Model Content

[0031] First embodiment

[0032] Please refer to Figure 1-Figure 4 One embodiment of the utility model provides a toothbrush handle, including a brush head connecting part 10, a first elastic part 20, a gripping part 30 and a second elastic part 40 connected in sequence, the brush head connecting part 10 is used to connect the toothbrush head 100, the gripping part 30 is used for being gripped by a human hand, and the outer diameter L1 of the first elastic part 20 and the outer diameter L2 of the second elastic part 40 are both larger than the outer diameter L3 of the gripping part 30.

[0033] Specifically, the first elastic part 20 and the second elastic part 40 are installed at both ends of the grip part 30 of the toothbrush handle, and the outer diameter L1 of the first elastic part 20 and the outer diameter L2 of the second elastic part 40 are greater than the outer diameter L3 of the grip part 30, so that when the toothbrush falls on the ground, the first elastic part 20 and the second elastic part 40 can provide a buffering force for the grip part 30 to prevent the grip part 30 from being damaged or broken, thereby protecting the internal structure of the grip part 30 and reducing the impact on the aesthetics of the toothbrush. For example, when the toothbrush falls vertically, the second elastic part 40 located at the tail of the grip part 30 first contacts the ground, and the elastic deformation of the second elastic part 40 reduces the impact force on the grip part 30; when the toothbrush falls parallel to the bottom surface, the first elastic part 20 and the second elastic part 40 hold the grip part 30 in the middle, and the grip part 30 does not contact the ground, thereby preventing the grip part 30 from breaking. The arrangement of the first elastic portion 20 and the second elastic portion 40 can protect the grip portion 30 when the toothbrush falls to the ground from different directions, thereby extending the service life of the toothbrush handle.

[0034] Currently, there are aluminum alloy / zinc alloy / metal toothbrush handles on the market, but the production process of such products is a high-energy consumption industry, and the excessive carbon emissions generated are not in line with environmental protection goals.

[0035] Compared with metal and plastic parts, the ceramic production process has a relatively small impact on the environment: According to the China Ceramic Industry Development Report (2022), the energy consumption per ton of product for ceramic production is about 1,000 kWh, while the energy consumption per ton of product for plastic and metal parts production is about 2,000 kWh and 3,000 kWh respectively.

[0036] In this embodiment, the grip portion 30 is made of ceramic or glass.

[0037] Specifically, inorganic non-metallic materials such as ceramics and glass are resistant to moisture and high temperature, and have a better feel than plastic or metal materials. The grip 30 is made of ceramic or glass materials, which can further increase the service life of the toothbrush handle and improve the user's practical experience.

[0038] In addition, ceramic handles have many advantages, such as but not limited to: long service life of ceramics: ceramic products have a long service life and will not generate new pollution during use; ceramic handles can provide a cool feeling to enhance the consumer experience; ceramic handles are also more resistant to chemical corrosion; compared to metal handles, some components of which can produce allergens, ceramics are more friendly to users with allergic skin.

[0039] In this embodiment, a first connecting column 50 is further included. One end of the holding portion 30 has a first plug hole 31. The first connecting column 50 is used to connect the first elastic portion 20 and is interference fit with the first plug hole 31 so that the first elastic portion 20 and the holding portion 30 are detachably connected.

[0040] Furthermore, it also includes a second connecting column 70. One end of the gripping portion 30 has a second plug hole. The second connecting column 70 is used to connect the second elastic portion 40 and is interference fit with the second plug hole so that the second elastic portion 40 and the gripping portion 30 are detachably connected.

[0041] It should be noted that the second plug-in hole can be a through hole connected to the first plug-in hole 31, so that the holding portion 30 forms a cylindrical structure. The first plug-in hole 31 and the second plug-in hole can also be a groove-type structure located at both ends of the holding portion 30. The name "hole" here is only for the convenience of description and should not be a limitation of this structure.

[0042] In this embodiment, a first convex rib 51 is disposed on the surface of the first connecting column 50 . The first convex rib 51 extends along the length direction of the first connecting column 50 to prevent the first connecting column 50 from rotating relative to the gripping portion 30 .

[0043] Furthermore, a second convex rib 71 is disposed on the surface of the second connecting column 70 . The second convex rib 71 extends along the length direction of the second connecting column 70 , and is used to prevent the second connecting column 70 from rotating relative to the gripping portion 30 .

[0044] Specifically, the rib 51 can ensure that the first connecting part is in the first plug-in hole 31 and the second connecting column 70 is in the second plug-in hole with an interference fit, and the rib 51 can also prevent the first connecting column 50 and the second connecting column 70 from rotating relative to the gripping part 30 during use of the toothbrush, thereby avoiding practical problems with the toothbrush.

[0045] In this embodiment, a first anti-slip structure 60 is further included. The first anti-slip structure 60 connects the first elastic portion 20 and the gripping portion 30 . The thickness of the first anti-slip structure 60 increases from the gripping portion 30 toward the first elastic portion 20 .

[0046] Specifically, since the toothbrush is attached with liquid during use, the user may easily hold it unsteadily, causing it to slip. By adding the first anti-slip structure 60, the probability of the toothbrush slipping can be reduced. The thickness of the first anti-slip structure 60 increases from the gripping part 30 to the first elastic part 20, which can provide a transition for the user's hand and avoid an abrupt feeling.

[0047] Furthermore, the surface of the first anti-slip structure 60 is provided with threads.

[0048] In this embodiment, a second anti-slip structure 80 is further included. The second anti-slip structure 80 connects the second elastic portion 40 and the gripping portion 30 . The thickness of the second anti-slip structure 80 increases from the gripping portion 30 toward the second elastic portion 40 .

[0049] Specifically, the second anti-slip structure 80 can be similar in design to the first anti-slip structure 60, and together with the first anti-slip structure 60, increase the friction of the user's hand and improve the stability of the toothbrush during use.

[0050] like Figure 3 As shown, in this embodiment, the first anti-slip structure 60 is tubular and is used to be sleeved on one end of the grip portion 30 . The wall thickness of the first anti-slip structure 60 gradually decreases from the first elastic portion 20 toward the grip portion 30 .

[0051] Specifically, the first anti-slip structure 60 is tubular, and the first connecting column 50 is connected to the first elastic part 20 and passes through the first anti-slip structure 60 to be plugged into the holding part 30. After the first connecting column 50 and the first plugging hole 31 of the holding part 30 are plugged in, the first anti-slip structure 60 wraps one end of the holding part 30. The gradually decreasing wall thickness of the first anti-slip structure 60 helps to enhance the fit with the holding part 30.

[0052] In other embodiments, the first elastic portion 20, the first connecting column 50 and the first anti-slip structure 60 are preferably integrally formed, and the first elastic portion 20, the first anti-slip structure 60 and the first connecting column 50 are connected in sequence.

[0053] In this embodiment, the outer diameter of the first elastic portion 20 is greater than the outer diameter of the grip portion 30 by 2 mm or more.

[0054] Specifically, the difference between the outer diameter of the first elastic part 20 and the outer diameter of the grip part 30 is more than 2 mm, so that the first elastic part 20 can protect the grip part 30, so that the first elastic part 20 can still contact the ground before the grip part 30 when the toothbrush falls at a larger angle. In addition, it is necessary to consider that the elastic deformation of the first elastic part 20 will reduce the difference in outer diameter with the grip part 30. Therefore, the difference in outer diameter between the first elastic part 20 and the grip part 30 is greater than 2 mm, which is a necessary design to ensure that the first elastic part 20 has a protective effect on the grip part 30.

[0055] Furthermore, the outer diameter of the second elastic portion 40 is at least 2 mm greater than the outer diameter of the grip portion 30 .

[0056] In this embodiment, the length of the gripping portion 30 is 0.25-4 times the length of the first elastic portion 20 .

[0057] Specifically, the longer the grip portion 30 made of ceramic or glass is, the easier it is to break. If the length is too long, even if the grip portion 30 does not directly contact the ground, it may be affected by stress and break. Therefore, the length of the grip portion 30 and the first elastic portion 20 must be within an appropriate ratio to ensure effective protection of the first elastic portion 20. In practical applications, the length of the grip portion 30 is specifically 0.5 times, 0.9 times, 1 times, 2.2 times, 2.7 times, 3 times, 3.6 times or 3.8 times the length of the first elastic portion 20, etc., which is not limited here.

[0058] Furthermore, the length of the gripping portion 30 is 0.25-4 times the length of the first elastic portion 20 .

[0059] The toothbrush handle provided by the utility model is provided with a first elastic part 20 and a second elastic part 40 with an outer diameter larger than the grip part 30 at both ends of the grip part 30, thereby preventing the grip part 30 from being directly broken when the toothbrush handle falls to the ground. This also expands the material selection range of the grip part 30 to a certain extent, and thus ceramic or glass materials that are easier to clean and have a better hand feel but are highly brittle can be selected, thereby improving the fashion sense and economic value of the toothbrush, extending the service life of the toothbrush handle, and reducing the pollution problem caused by the overall replacement of the toothbrush.

[0060] Second embodiment

[0061] Please refer to Figure 5 and Figure 6 Another embodiment of the present invention provides a toothbrush, comprising a toothbrush head 100 and a toothbrush handle as described in the first embodiment, wherein the toothbrush head 100 is detachably connected to the brush head connecting portion 10 .

[0062] Specifically, the detachable connection between the toothbrush head 100 and the toothbrush handle can facilitate the replacement of the toothbrush head 100, and the toothbrush handle can be reused, thereby improving environmental protection.

[0063] In this embodiment, the brush head connecting portion 10 is provided with a connecting shaft 11, and the connecting shaft 11 and the toothbrush head 100 are threadedly connected.

[0064] Specifically, the threaded connection has the characteristics of being stable and firm in use.

[0065] In other embodiments, the brush head connection part 10 and the toothbrush head 100 may also be magnetically connected, which can achieve quick installation and removal, saving the user's time. At the same time, the magnetic connection can also prevent the toothbrush head from falling off, improving the safety of use. The connection method listed in this embodiment is only for example, and does not limit the connection method of the brush head connection part 10 and the toothbrush head 100. The conventional connection method of the brush head and the brush handle on the market can be applied.

[0066] Furthermore, the total length of the toothbrush is 180-210 mm, preferably 194-200 mm; the length of the grip portion 30 is 50-80 mm, preferably 60-65 mm;

[0067] The length of the first elastic portion 20 or the second elastic portion 40 is 20-50 mm, preferably, the length of the first elastic portion 20 is 20-25 mm, and the length of the second elastic portion 40 is preferably 38-42 mm;

[0068] The length of the toothbrush head 100 is 50-80 mm, preferably 68-72 mm.
