Description

Technical Field

[0001] This utility model relates to the field of cleaning tools technology, specifically to a toothbrush with an easy-to-replace brush head. Background Technology

[0002] A toothbrush is a cleaning product with a handle. It is used to apply toothpaste to the brush head and then repeatedly brush all parts of the teeth. Usually, the toothbrush and toothpaste are separate; when brushing your teeth, you need to squeeze toothpaste onto the brush head and then begin brushing.

[0003] With societal development, existing toothbrushes now offer the function of dispensing toothpaste, making it convenient for users. However, it's well known that toothbrush heads can become damaged over time, leading to reduced cleaning power. Therefore, the recommended replacement time for toothbrush heads is every three months. However, existing toothbrushes with dispensing functions have the brush head and handle integrated, making complete replacement inconvenient from both a production and energy conservation perspective, thus hindering the replacement of the brush head individually. Utility Model Content

[0004] In view of this, the present invention provides a toothbrush with an easy-to-replace brush head. The brush head and handle can be detached and reassembled quickly, which is more energy-efficient and environmentally friendly, and makes replacement simpler and more convenient.

[0005] To solve the above-mentioned technical problems, this utility model provides a toothbrush with an easy-to-replace brush head, including a grip, a cleaning part disposed at the end of the grip, and a quick-change component between the cleaning part and the grip. The quick-change component includes a flexible sleeve fitted over the outside of the cleaning part, and the tail of the cleaning part is inserted into the other end of the flexible sleeve and abuts against the end of the grip. This utility model can achieve convenient, quick and efficient disassembly and installation of the grip and the cleaning part through the quick-change component. When the cleaning part is worn and needs to be replaced, there is no need to replace the whole thing. Just separate the cleaning part from the grip and then insert the new cleaning part into the flexible sleeve to continue using the toothbrush, which is more energy-saving and environmentally friendly.

[0006] The cleaning part has a pin hole, and the flexible sleeve has a through hole. After the cleaning part is inserted into the flexible sleeve and its bottom abuts against the end of the grip, the axis of the through hole and the pin hole coincides. A pin is inserted into the axis after the through hole and the pin hole coincide. This utility model can achieve the integrated fixation of the cleaning part, the flexible sleeve, and the grip by inserting one end of the flexible sleeve into the front end of the grip and then inserting the cleaning part into the other end of the flexible sleeve, so that the axis of the through hole on the flexible sleeve coincides with the axis of the pin hole on the cleaning part. Then, the pin is inserted through the through hole into the pin hole. This greatly increases the stability of the user when brushing teeth and effectively avoids the risk of the cleaning part easily slipping or separating due to the detachable connection between the cleaning part and the grip.

[0007] The flexible sleeve has a protective sleeve at its end. The protective sleeve can both orient the installation position of the flexible sleeve and limit the depth of the cleaning part into the oral cavity. This can prevent children from gagging or scratching the oral mucosa due to insufficient control of the brushing force.

[0008] The diameter of the protective sleeve is larger at the end near the cleaning part than at the end near the grip. This is to ensure that the protective sleeve can smoothly and efficiently connect the grip and cleaning parts, making the process more effortless and convenient.

[0009] The protective cover is made of silicone to ensure good flexibility and skin-friendly comfort.

[0010] The grip is made of plastic to reduce its weight and increase user comfort.

[0011] The flexible sleeve is made of plastic to ensure it has a certain degree of flexibility, making it easy to connect the cleaning part and the grip part.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. This utility model achieves the goal of making the cleaning part and the grip part detachable. When the cleaning part is worn and needs to be replaced, there is no need to replace the entire toothbrush. Simply separate the cleaning part from the grip part and reattach the new cleaning part to the original grip part to continue normal use of the toothbrush. This is more energy-efficient and environmentally friendly, greatly reduces production and usage costs, and makes operation more convenient and efficient.

[0014] 2. This utility model allows the cleaning part and the holding part to be engaged by inserting one end of the flexible sleeve into the holding part and inserting the tail of the cleaning part from the other end of the flexible sleeve until the tail of the cleaning part abuts against the end of the holding part. Then the toothbrush can be used normally.

[0015] 3. After the cleaning part and the gripping part are inserted into the corresponding positions in the flexible sleeve, the axis of the through hole on the flexible sleeve coincides with the pin hole at the end of the gripping part. Then, the operator inserts the pin through the through hole into the pin hole in sequence, which can realize the fastening operation of the cleaning part and the gripping part after the snap-fit ​​is completed, greatly increasing the stability and firmness of the combination of the gripping part and the cleaning part.

[0016] 4. This utility model can achieve convenient and quick orientation of the installation position of the flexible sleeve by setting a protective sleeve at the end of the flexible sleeve, and can also control the depth of the cleaning part of the toothbrush entering the oral cavity, making the operation safer and more convenient.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] like Figure 1 and Figure 2As shown: This embodiment provides a toothbrush with an easy-to-replace brush head, including a grip 100. The grip 100 is made of plastic to reduce its weight and increase user comfort. A cleaning part 200 is located at the end of the grip 100. A quick-change assembly 300 is provided between the cleaning part 200 and the grip 100. The quick-change assembly 300 includes a flexible sleeve 301 that is fitted over the outside of the cleaning part 200. The tail of the cleaning part 200 is inserted into the other end of the flexible sleeve 301 and abuts against the end of the grip 100. The cleaning part 200 includes a fixing rod, a fixing seat at the end of the fixing rod, and multiple sets of bristles on the fixing seat. The bristles are made of nylon, PTB, or polypropylene, and each set of bristles is wrapped with... The cleaning part 200 has pin holes, and the flexible sleeve 301 has through holes. It is made of one or a combination of cleaning, carbon, or silicone. Carbon bristles are limited to economic or temporary use, such as disposable toothbrushes in hotels, because the bristles of this material will deform after 1-2 uses. After the cleaning part 200 is inserted into the flexible sleeve 301 and its bottom abuts against the end of the grip part 100, the axis of the through hole and the pin hole coincides. A pin 302 is inserted on the axis after the through hole and the pin hole coincide. The pin 302 passes through the upper part of the through hole and enters the pin hole opened on the grip part 100 coaxial with it, so that the grip part 100, the flexible sleeve 301 and the cleaning part 200 assembled together can be firmly and stably detachably connected.

[0024] This invention allows for the integrated fixation of the cleaning part 200, the flexible sleeve 301, and the gripping part 100 by inserting one end of the flexible sleeve 301 into the front end of the gripping part 100 and then inserting the cleaning part 200 into the other end of the flexible sleeve 301, aligning the axis of the through hole on the flexible sleeve 301 with the axis of the pin hole on the cleaning part 200. Then, the pin 302 is inserted through the through hole into the pin hole, thus achieving a unified fixation of the cleaning part 200, the flexible sleeve 301, and the gripping part 100. This significantly increases the stability of the user's brushing experience and effectively avoids the risk of the cleaning part 200 easily slipping or separating due to the detachable connection between the cleaning part 200 and the gripping part 100.

[0025] Another implementation of the detachable connection is to open a threaded hole in the grip 100, and open a through hole in the flexible sleeve 301 with an inner diameter larger than the maximum diameter of the threaded hole. Then, a plastic screw is inserted into the through hole on the flexible sleeve 301 after docking, and then screwed into the threaded hole on the grip 100. This achieves a quick and convenient detachable connection between the grip 100, the flexible sleeve 301, and the cleaning part 200, making the operation more convenient and efficient.

[0026] This invention enables convenient, quick, and efficient disassembly and installation of the grip 100 and the cleaning part 200 via the quick-change component 300. When the cleaning part 200 is worn and needs to be replaced, there is no need to replace the whole unit. Simply separate the cleaning part 200 from the grip 100 and insert the new cleaning part 200 into the flexible sleeve 301 to continue using the toothbrush, which is more energy-efficient and environmentally friendly.

[0027] According to another embodiment of the present invention, such as Figure 1 and Figure 4 As shown, the end of the flexible sleeve 301 is provided with a protective sleeve 400. The protective sleeve 400 is a silicone sleeve or a latex sleeve. The purpose of this is to ensure that it has good flexibility and skin-friendly comfort. The diameter of the end of the protective sleeve 400 near the cleaning part 200 is larger than the diameter of the end near the grip part 100. The end of the protective sleeve 400 is bonded to the flexible sleeve 301. The protective sleeve 400 can, on the one hand, orient the installation position of the flexible sleeve 301, and on the other hand, limit the depth of the cleaning part 200 into the oral cavity, so as to avoid gagging or scratching the oral mucosa caused by children not controlling the force properly during brushing.

[0028] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the flexible sleeve 301 is a plastic sleeve, or it can be a rubber sleeve. The purpose of this is to ensure that it has a certain degree of toughness, so as to facilitate easy insertion of the cleaning part 200 and the gripping part 100.

[0029] How to use this utility model:

[0030] First, it needs to be clarified that the toothbrush involved in this utility model is mainly intended for use in non-hotel disposable scenarios, primarily for home and long-term use. This utility model uses the replacement of the cleaning part 200 (i.e., the brush head after wear) as an example to illustrate its usage method in detail. When the cleaning part 200 needs to be replaced, the user first pulls the pin 302 out of the pin hole until its lower part disengages from the pin hole. Then, the operator holds the protective sleeve 400 at the end of the flexible sleeve 301 and pulls the cleaning part 200 out of the flexible sleeve 301. Next, the through hole at the tail of the new cleaning part is aligned with the pin hole, and the tail of the cleaning part 200 is inserted into the flexible sleeve 301 until its tail abuts against the top of the grip part 100. When the through hole on the flexible sleeve 301 coincides with the axis of the pin hole on the grip 100, the operator inserts the pin 302 from the top of the through hole downwards into the pin hole, thus realizing the detachable connection between the cleaning part 200 and the grip 100. This utility model, by making the cleaning part 200 and the grip 100 detachable, allows the toothbrush to be used normally again when the cleaning part 200 is worn and needs to be replaced, without replacing the entire toothbrush. Simply separate the cleaning part 200 from the grip 100 and detachably fix the new cleaning part 200 to the original grip 100. This is more energy-efficient and environmentally friendly, greatly reducing production and usage costs, and making operation more convenient and efficient.

[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
