Description

Technical Field

[0001] This utility model relates to the field of toothbrush technology, specifically a toothbrush handle with a built-in toothpaste storage compartment. Background Technology

[0002] A toothbrush is a brush used to clean teeth. Generally, toothpaste is applied to the toothbrush when brushing. Toothbrushes are essential in daily life. The brush head is typically square or diamond-shaped. A square brush head can effectively clean every surface of the teeth, while a diamond-shaped brush head has a pointed tip, making it easier to reach deeper into the mouth. Toothbrushes can clean teeth regardless of their head shape; however, the size of the brush head must be considered in conjunction with factors such as mouth size, mouth opening degree, and personal habits. It's best to use a smaller brush head to reach deeper into the mouth, ensuring flexible rotation and cleaning of the back teeth.

[0003] Currently, for people who travel for business or leisure, separating toothpaste and toothbrush takes up a lot of space. Household toothbrushes and toothpaste are relatively large and inconvenient to carry when traveling. For people on short trips, it is unnecessary to carry a lot of toothpaste, as it lacks flexibility. Therefore, we have proposed a toothbrush handle with a built-in toothpaste storage compartment. Utility Model Content

[0004] The purpose of this utility model is to provide a toothbrush handle with a built-in toothpaste storage compartment to solve the problems in the prior art. For people who travel for business or leisure, the toothpaste and toothbrush are separate and take up a lot of space. Household toothbrushes and toothpaste are also large and inconvenient to carry when traveling. For people who travel for short distances, it is unnecessary to carry a lot of toothpaste, resulting in a lack of flexibility.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a toothbrush handle with a built-in toothpaste storage compartment, including a connecting rod, a storage mechanism at one end of the connecting rod, a sealing mechanism at the other end of the connecting rod, a brush head fixed to one side of the sealing mechanism, a discharge channel penetrating through the middle of one side of the inner cavity of the connecting rod, a sealing ring fixed to one side of one side of the inner cavity of the connecting rod, and a through cavity inside the brush head;

[0006] The storage mechanism includes a storage handle screwed to one end of the connecting rod. A sliding groove is provided through the outer side of the storage handle. A push post slides in the inner cavity of the storage handle. A sealing piston is fixed to one end of the push post. A push block is fixed to the outer side of the push post.

[0007] Preferably, the storage mechanism further includes card holes evenly distributed on both sides of the slide groove, and a contraction cavity is provided on both sides of the push block. A return spring is fixed in the middle of one side of the contraction cavity, a circular plate is fixed at one end of the return spring, and a card head is fixed in the middle of one side of the circular plate.

[0008] Preferably, the circular plate slides inside the contraction cavity, and the outer wall of the circular plate is in contact with the inner wall of the contraction cavity to limit the circular plate and make the circular plate move stably inside the contraction cavity.

[0009] Preferably, the push block slides inside the groove, and the two sides of the push block are in contact with the two sides of the groove, so that the push block moves stably inside the groove. The outer wall of the sealing piston is in contact with the inner wall of the storage handle to seal and prevent toothpaste leakage.

[0010] Preferably, the card hole is hemispherical, and the end of the card head is hemispherical, which facilitates the connection between the card head and the card hole.

[0011] Preferably, the sealing mechanism includes a housing fixed to the other end of the connecting rod. A rotating cavity is formed on one side of the housing. A through hole is symmetrically formed through the inner wall of the rotating cavity. A limit groove is formed at the bottom of the inner wall of the rotating cavity. A torsion spring is fixed at the bottom of the rotating cavity. A rotating column rotates inside the rotating cavity. A limit ring is fixed at the bottom of the outer wall of the rotating column. A connecting hole is formed through the outer wall of the rotating column. A knob is fixed at the bottom end of the rotating column. An indicator needle is fixed on the outer wall of the knob.

[0012] Preferably, the outer wall of the rotating column is fixed with sealing rubber, and the sealing rubber is in contact with the inner wall of the rotating cavity for sealing. The limiting ring is located inside the limiting groove, and one end of the torsion spring is fixed to one side of the limiting ring to facilitate the limiting ring to reset.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application utilizes a storage mechanism that allows toothpaste to be squeezed into the storage handle when out and about. The storage handle is then connected to the connecting rod, and by pushing the push block, the push column moves, causing the sealed piston to move, directly squeezing the stored toothpaste into the brush head. This avoids the toothpaste and toothbrush being separated and taking up more space, making it convenient to carry when traveling and improving flexibility. Furthermore, the cooperation between the clip and the clip hole facilitates the precise dispensing of toothpaste, making it easy to use and improving the practicality of the device.

[0015] 2. In this application, the sealing mechanism allows for the rotation of the rotating column by turning the knob during use. This rotation is indicated by the indicator needle and simultaneously causes the torsion spring to deform, aligning the through hole, connecting hole, and discharge channel. This facilitates the squeezing of toothpaste into the brush head. After squeezing, the knob is loosened, and the torsion spring resets, causing the limit ring to reset as well. This resets the rotating column, misaligning the connecting hole and the through hole. This prevents wastewater from entering the storage handle during brushing, thus preventing contamination of the remaining toothpaste and ensuring cleanliness. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figures 1-5As shown, this utility model provides a technical solution for a toothbrush handle with a built-in toothpaste storage compartment, including a connecting rod 100, a storage mechanism 200 at one end of the connecting rod 100, a sealing mechanism 300 at the other end of the connecting rod 100, a brush head 400 fixed on one side of the sealing mechanism 300, a discharge channel 110 through the middle of one side of the inner cavity of the connecting rod 100, a sealing ring 120 fixed on one side of the inner cavity of the connecting rod 100, and a through cavity 410 inside the brush head 400;

[0025] Please see Figure 2 , Figure 3 and Figure 4 The storage mechanism 200 includes a storage handle 210 screwed to one end of a connecting rod 100. A groove 220 is provided through the outer side of the storage handle 210. A push post 230 slides in the inner cavity of the storage handle 210. A sealing piston 240 is fixed to one end of the push post 230. A push block 250 is fixed to the outer side of the push post 230. The storage mechanism 200 also includes locking holes 221 evenly provided on both sides of the groove 220. A contraction cavity 260 is provided on both sides of the push block 250. A return spring 270 is fixed to the middle of one side of the contraction cavity 260. A circular plate 280 is fixed to one end of the return spring 270. A locking head 290 is fixed to the middle of one side of the circular plate 280. The circular plate 280 slides inside the contraction cavity 260, and the outer side wall of the circular plate 280 is in contact with the inner side wall of the contraction cavity 260. The pusher 250 slides inside the groove 220, and the two sides of the pusher 250 are in contact with the two sides of the groove 220. The outer side wall of the sealing piston 240 is in contact with the inner side wall of the storage handle 210. The card hole 221 is hemispherical, and the end of the card head 290 is hemispherical. With the storage mechanism 200, toothpaste can be squeezed into the storage handle 210 when going out. Then, the storage handle 210 is connected to the connecting rod 100. By pushing the pusher 250, the pusher 230 moves, which moves the sealing piston 240, and the stored toothpaste is squeezed directly into the brush head 400. This avoids the toothpaste and toothbrush from being separated and taking up more space, making it convenient to carry when traveling and improving flexibility. In addition, the cooperation of the card head 290 and the card hole 221 makes it easy to squeeze out a certain amount of toothpaste, which is convenient to use and improves the practicality of the device.

[0026] Please see Figure 5 and Figure 6The sealing mechanism 300 includes a housing 310 fixed to the other end of the connecting rod 100. A rotating cavity 320 is formed on one side of the housing 310. Through holes 321 are symmetrically formed through the inner wall of the rotating cavity 320. A limit groove 322 is formed at the bottom of the inner wall of the rotating cavity 320. A torsion spring 330 is fixed at the bottom of the rotating cavity 320. A rotating column 340 rotates inside the rotating cavity 320. A limit ring 341 is fixed at the bottom of the outer wall of the rotating column 340. A connecting hole 350 is formed through the outer wall of the rotating column 340. A knob 360 is fixed at the bottom end of the rotating column 340. An indicator needle 370 is fixed on the outer wall of the knob 360. Sealing rubber is fixed on the outer wall of the rotating column 340, and the sealing rubber is in contact with the inner wall of the rotating cavity 320. The limiting ring 341 is located inside the limiting groove 322, and one end of the torsion spring 330 is fixed to one side of the limiting ring 341. With the sealing mechanism 300, when in use, rotating the knob 360 drives the rotating column 340 to rotate 90 degrees, and the indicator needle 370 indicates the rotation. At the same time, the torsion spring 330 deforms, thereby aligning the through hole 321, the connecting hole 350 and the discharge channel 110, so that toothpaste can be squeezed into the brush head 400. After squeezing, loosening the knob 360 causes the torsion spring 330 to reset, which in turn resets the limiting ring 341, thereby resetting the rotating column 340 and causing the connecting hole 350 to be misaligned with the through hole 321. This prevents dirty water from entering the storage handle 210 during brushing, prevents contamination of the remaining toothpaste, and ensures cleanliness.

[0027] In use, toothpaste is squeezed into the storage handle 210, and then the storage handle 210 is connected to the connecting rod 100. When squeezing toothpaste, the knob 360 is turned, causing the rotating column 340 to rotate 90 degrees. The indicator needle 370 indicates the rotation, and at the same time, the torsion spring 330 is deformed, thereby aligning the through hole 321, the connecting hole 350, and the discharge channel 110. This pushes the push block 250, causing the locking hole 221 to press against the locking head 290, which moves the locking head 290 along with the circular plate 280, pressing against the return spring 270. As the push block 250 moves, it drives the push column 230 to move, bringing the toothpaste into place. The piston 240 moves to squeeze the stored toothpaste directly into the brush head 400. When the clip 290 aligns with the clip hole 221, the reset spring 270 causes the circular plate 280 to move the clip 290 back to its original position, so that the clip 290 is embedded in the clip hole 221, thus completing the quantitative extrusion. After extrusion, the knob 360 is loosened, and the torsion spring 330 resets, causing the limit ring 341 to reset, thereby resetting the rotating column 340 and misaligning the connecting hole 350 with the through hole 321. This prevents dirty water from entering the storage handle 210 during brushing and prevents the toothpaste inside the storage handle 210 from being contaminated.
