Description

Technical Field

[0001] The utility model relates to the technical field of dental floss boxes, in particular to a dental floss box for facilitating the pushing out of dental floss. Background Art

[0002] Dental floss is widely used in people's daily life. Using dental floss after meals can conveniently clean teeth and effectively prevent the occurrence of tooth diseases.

[0003] In order to facilitate people's use of dental floss, there are currently dental floss boxes on the market for containing dental floss. For example, the utility model patent with the publication number CN220293686U applied by the applicant discloses an automatic dental floss box that can push out dental floss in two directions simultaneously, facilitating two users in opposite directions to obtain dental floss for cleaning at the same time. However, during the use of the product, it is often found that the dental floss cannot be smoothly pushed out. For example, when the dental floss is pushed outwards by the pushing component, the dental floss shakes and gets stuck inside the dental floss box, unable to be smoothly pushed out; another example is that when the dental floss is stacked on top of each other to form a pallet inside the dental floss box, since the dental floss requires a certain amount of space to ensure that there is always dental floss at the bottom of the dental floss box for the pushing component to push it out, this also leads to the easy deviation of the dental floss pallet from its position and inability to maintain the established position state, and the pushing component cannot smoothly push it out; yet another example is that due to the large contact area between the dental floss and the internal components of the dental floss box, the friction between the dental floss and the internal components of the dental floss box is increased, hindering the movement of the dental floss towards the bottom of the dental floss box. At the same time, due to the large contact area between the dental floss and the internal components of the dental floss box, the dental floss is also easily caught on the burrs of the internal components of the dental floss.

[0004] Therefore, there is an urgent need for a dental floss box that can smoothly push out dental floss to solve the above technical problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a dental floss box for facilitating the pushing out of dental floss. To solve the above technical problems, the utility model adopts the following technical solutions:

[0014] Furthermore, a baffle for closing the outlet is arranged on the housing. The first end of the baffle is rotatably connected to the housing. The second end of the baffle extends towards the box body and closes the outlet. An elastic member is arranged inside the chamber. One end of the elastic member is detachably connected inside the chamber, and the other end is detachably connected to the first end of the baffle. And the connection position of the elastic member and the first end of the baffle is located below the axis of the rotating shaft where the baffle is rotatably connected to the housing.

[0015] Furthermore, the box body includes:

[0016] A main body, on which a cavity with one end being open is opened;

[0017] A cover body, which covers the opening of the cavity. A first rod for sleeving a plurality of dental flosses therein and a second rod for limiting the middle section of the dental floss are fixedly installed on the cover body. And a gap adapted to the height dimension of the dental floss is formed among the first rod, the second rod and the bottom of the cavity.

[0018] Further, the first rod and the second rod are both formed with spacer strips, and the spacer strips are arranged along the length directions of the first rod and the second rod and protrude towards the dental floss direction.

[0019] Further, a guiding seat is also formed inside the box body. The guiding seat is fixedly arranged at the bottom of the cavity and on the side far away from the outlet. The upper end of the guiding seat is set as a guiding inclined surface for guiding the tail of the dental floss.

Detailed implementation manners

[0032] For the convenience of those skilled in the art to understand, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation manners does not limit the present utility model. The present utility model will be described in detail below with reference to the accompanying drawings.

[0033] The embodiment of the present utility model provides a dental floss box for conveniently pushing out dental floss 001, which can smoothly push out the dental floss 001 in the dental floss box, facilitating users to clean their teeth. As Figure 1-8 shown, a dental floss box for conveniently pushing out dental floss 001 provided by the embodiment of the present utility model includes a box body 100 and a pushing mechanism 200. A plurality of dental flosses 001 are stacked on top of each other to form a dental floss stack and are placed inside the box body 100. An outlet 101 adapted to the dental floss 001 is provided on the side surface at the lower end of the box body 100. The pushing mechanism 200 is installed at the lower end of the box body 100 to push the dental floss 001 at the lowermost layer along the outlet 101, that is, Figure 2 the state shown, thus facilitating users to use. As Figures 3-7As shown, the ejection mechanism 200 includes a shell 210 which is installed at the lower end of the box body 100 and has a chamber 211 therein, a driving device 230 installed in the chamber 211, and an ejection arm 220 driven by the driving device 230, wherein the ejection arm 220 is slidably connected to the shell 210 and is formed with an ejection portion 221 protruding toward the inside of the box body 100. Accordingly, a avoidance groove 102 is provided on the bottom of the box body 100 for the ejection portion 221 to pass through and extend into the inside of the box, and a groove 222 which is adapted to the height size of the dental floss 001 is provided on the end of the ejection portion 221. The ejection arm 220 is transmission-connected to the driving device 230, and slides along the shell 210 under the drive of the driving device 230, and makes the ejection portion 221 move toward the outlet 101, so that the dental floss 001 is ejected at the outlet 101 for the user to clean teeth.

[0034] During the use of the dental floss 001, the driving device 230 drives the push-out arm 220 to move along the housing 210, so that the push-out portion 221 contacts the dental floss 001 at the bottom of the box 100, and the rod at the head of the dental floss 001 is inserted into the groove 222. The groove 222 is used to limit the movement, and during the movement of the push-out arm 220, the dental floss 001 is pushed out at the outlet 101. During the entire pushing process, the dental floss 001 is limited in the groove 222, so that it can be pushed out smoothly, and will not be stuck on the side wall of the outlet 101 due to the movement of the dental floss 001.

[0035] In this embodiment, if Figures 4-7 As shown, a mounting plate 212 is fixedly provided in the chamber 211 of the shell 210, and the ejection arm 220 is slidably provided on the mounting plate 212 and the top of the chamber 211. At the same time, a sliding groove 213 is provided on the top of the chamber 211 for the ejection portion 221 to pass through and be slidably connected thereto. By slidingly setting the ejection arm 220 between the mounting plate 212 and the top of the chamber 211, the sliding process of the ejection arm 220 can be made more stable, and the ejection stability of the dental floss 001 is affected less by shaking or swaying.

[0036] In a further improved solution of this embodiment, the pushing arm 220 includes a bottom plate 223 in a strip structure. The pushing portion 221 is formed on the bottom plate 223, and the bottom plate 223 is in transmission connection with the driving device 230. At least one sliding groove 224 is formed on the bottom plate 223. At the same time, a guiding block 214 that forms a sliding pair with the sliding groove 224 is formed on the mounting plate 212 or the top of the chamber 211. In this embodiment, the sliding groove 224 is formed on the upper side surface of the bottom plate 223, and the guiding block 214 is formed on the bottom of the chamber 211, so that the pushing arm 220 can reciprocate along the direction of the guiding block 214 when driven by the driving device 230.

[0037] In this embodiment, the driving device 230 includes a motor 231 fixedly installed in the chamber 211 and a gear 232 in transmission connection with the motor 231. A rack 225 that meshes with the gear 232 is formed on the bottom plate 223. The motor 231 drives the gear 232 to rotate, so as to drive the rack 225 that meshes with the gear 232 to drive the bottom plate 223 to reciprocate along the direction of the guiding block 214, completing the driving action of the pushing arm 220, so that the pushing portion 221 pushes the dental floss 001 out within the box body 100.

[0038] In order that when the pushing portion 221 retracts after pushing out the dental floss 001, the remaining dental floss 001 within the box body 100 will not interfere with the retraction of the pushing portion 221, as Figures 4-5 shown, the top surface of the pushing portion 221 is set as an inclined surface. Specifically, the top surface of the pushing portion 221 gradually descends in height toward the end away from the groove 222, so that the pushing portion 221 forms an inclined state where the end provided with the groove 222 is high and the end away from the groove 222 is low. Through the setting of the inclined surface, when the pushing portion 221 retracts, the dental floss 001 can be gradually lifted by the inclined surface of the pushing portion 221, facilitating the pushing portion 221 to retract to the starting position.

[0039] In this embodiment, a baffle 215 for closing the outlet 101 is further provided. When the dental floss 001 is not in use, the outlet 101 can be closed to prevent the dental floss 001 from falling out within the box body 100, and at the same time avoid external dirt from entering the box body 100 and contaminating the dental floss 001. As Figures 6-7As shown, the first end 216 of the baffle 215 is rotatably connected to the housing 210. The second end 217 of the baffle 215 extends towards the outlet 101 and closes the outlet 101 outside the cartridge 100. In this embodiment, the first end 216 of the baffle 215 is the lower end, and the second end 217 is the upper end. At the same time, an elastic member 218 is disposed within the chamber 211 of the housing 210. One end of the elastic member 218 is detachably connected within the chamber 211, and the other end is detachably connected to the first end 216 of the baffle 215. Moreover, the connection position of the elastic member 218 and the first end 216 is below the axis of the rotating shaft where the first end 216 of the baffle 215 is rotatably connected to the housing 210. Thus, under the downward elastic pulling force of the elastic member 218, the second end 217 of the baffle 215 flips upwards along the rotating shaft, so that the second end 217 of the baffle 215 overlaps on the outer surface of the cartridge 100 and closes the outlet 101.

[0040] In the embodiment of the present utility model, a groove 222 for receiving the dental floss 001 is provided on the pushing portion 221. Thus, when the dental floss 001 is pushed towards the outlet 101, the shaking of the dental floss 001 can be reduced, and the dental floss 001 can be prevented from being stuck by the side wall of the cartridge 100 at the outlet 101, which affects the smooth pushing of the dental floss 001. At the same time, by setting the bottom plate 223 of the pushing arm 220, the stability of the pushing arm 220 during sliding can be improved, and the situations of jitter and jumping can be reduced. Therefore, the stability of the dental floss 001 when being pushed is not affected.

[0041] Embodiment 1

[0042] The structure in this embodiment is basically the same as the above structure. In this embodiment, a specific example of the structure of the cartridge 100 is given. As Figure 3 、 8 shown, the cartridge 100 includes a main body 110 part and a cover 120. A cavity 111 is provided on the main body 110. An avoidance groove 102 is opened on the bottom surface of the main body 110. The outlet 101 is opened on the side surface at the lower end of the main body 110. An opening is provided at the upper end of the main body 110. The cover 120 is covered on the opening of the cavity 111. And a first rod 121 for the dental floss 001 to be sleeved therein and a second rod 122 for limiting the middle section of the dental floss 001 are fixedly installed on the cover 120. As Figure 3 、 8As shown, the wire part of the dental floss 001 is sleeved on the first rod 121, and they are stacked on top of each other for stacking. The second rod 122 interferes with the middle part of the dental floss 001, so that the middle part of the dental floss 001 is placed between the second rod 122 and the inner wall of the cavity 111, thereby limiting the position state of the dental floss 001 to keep it in a certain state, so that it is convenient for the pushing arm 220 to push it out. It can be imagined that in order to enable the dental floss 001 to be smoothly pushed out, a spacing gap is provided between the ends of the first rod 121 and the second rod 122 and the bottom of the cavity 111. This gap is adapted to the height dimension of the dental floss 001, so that the dental floss 001 at the bottom layer can be pushed out along this gap. At the same time, in order to reduce the contact area between the first rod 121, the second rod 122 and the dental floss 001, thereby affecting the movement of the dental floss 001 along the axial directions of the first rod 121 and the second rod 122, spacing strips 123 are formed on both the first rod 121 and the second rod 122. The spacing strips 123 are arranged along the length directions of the first rod 121 and the second rod 122 and protrude towards the dental floss 001. Thus, when the dental floss 001 comes into contact with the first rod 121 and the second rod 122, it is spaced by the spacing strips 123, thereby reducing the contact area between the first rod 121, the second rod 122 and the dental floss 001, reducing the frictional force, enabling the dental floss 001 to smoothly fall downward. At the same time, since the contact area between the dental floss 001 and the first rod 121 and the second rod 122 is reduced, the probability of the dental floss 001 being hooked on the burrs of the first rod 121 and the second rod 122 is reduced.

[0043] In order to ensure a fixed falling trajectory during the process of the dental floss 001 falling downward along the axes of the first rod 121 and the second rod 122 and ensure that the position state of the dental floss 001 is more fixed, a guide seat 112 is also provided within the box body 100. The guide seat 112 is arranged on the side of the bottom of the cavity 111 away from the outlet 101. At the same time, a guide inclined surface 113 is provided on the top surface of the upper end of the guide seat 112 to guide the tail of the dental floss 001. As Figure 8 shown, the guide inclined surface 113 is inclined towards the side wall of the cavity 111. Thus, during the process of the dental floss 001 falling down, the tail of the dental floss 001 is guided by the guide inclined surface 113 to move towards the side wall of the cavity 111, so that the tail of the dental floss 001 is guided to between the guide seat 112 and the side wall of the cavity 111, and its position state is fixed. The dental floss 001 is limited by the first rod 121, the second rod 122 and the guide seat 112, so that the dental floss 001 is three-point positioned, and the position state of the dental floss 001 can be always maintained, facilitating the smooth pushing out of the dental floss 001 by the pushing part 221.

[0044] Embodiment Two

[0045] In this embodiment, the main structure is the same as that of the above embodiment. The difference is that in this embodiment, a circuit component 240 is further provided in the driving mechanism. As Figure 4 shown, the circuit component 240 is disposed within the chamber 211 and includes a control circuit 241 electrically connected to the driving device 230 and a power supply unit 242 electrically connected to the control circuit 241. The power supply unit 242 supplies electrical energy to the control circuit 241, so that the control circuit 241 starts or stops the driving device 230 under the control of a preset control program. In this embodiment, the power supply unit 242 is a storage battery as an example.

[0046] The above are only preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Although the present invention is disclosed above in preferred embodiments, it is not intended to limit the present invention.
