Description
Technical Field
[0001] The utility model relates to a toothpaste squeezing device, belonging to the field of daily necessities. Background Art
[0002] Toothpaste is a necessity in daily life. When the toothpaste is almost used up, it is usually necessary to operate with both hands to squeeze out the toothpaste, and it is impossible to squeeze the toothpaste with one hand and dip the toothbrush into the toothpaste with the other hand. Moreover, once the hand is released, the toothpaste may retract into the tube, causing great inconvenience.
[0003] At present, there is a rotary toothpaste squeezing device on the market. Users can squeeze out the toothpaste by turning the knob, which can avoid the above-mentioned operation inconvenience. However, the turning action requires a large space. If this rotary toothpaste squeezing device is directly installed on the wall, when the user uses it, the turning action is restricted, and it is easy to scratch the skin at the finger joints. If the installation distance between the rotary toothpaste squeezing device and the wall is increased, the space occupied by the device will be increased, and the function of small and compact storage cannot be achieved. Summary of the Utility Model
[0004] In order to solve the above problems, the utility model provides a toothpaste squeezing device.
[0005] The utility model is realized by the following technical solutions:
[0006] A toothpaste squeezing device includes a clamping part, a driving part and a holding part. The driving part is movably installed on the holding part. The holding part is provided with an extrusion piece. The driving part includes a body and a handle fixed in the radial direction of the body, and the handle extends along the radial direction of the body to the outside of the body. The body is in transmission connection with the clamping part. When the body rotates axially to drive the clamping part to rotate axially, the extrusion piece generates extrusion on the toothpaste tube clamped by the clamping part.
[0007] In this technical solution, the handle is fixed in the radial direction of the body and extends along the radial direction of the body to the outside of the body. Compared with the rotary knob method in the background art, only by operating the handle can the body be driven to rotate axially. At this time, if the holding part is fixed on the wall, the axial direction of the body is horizontally installed and parallel to the wall, and the handle is pulled downwards, the body rotates axially, driving the clamping part to rotate axially, and then the extrusion piece squeezes out the toothpaste. This converts the turning action in the prior art into an up-and-down pressing action on the handle, avoiding the friction between the fingers and the wall during use, and the handle has a certain length, increasing the acting moment, and the operation is more labor-saving.
[0008] Preferably, the driving part includes a body and a bearing. The body is drivingly connected to the clamping part through the bearing. This preferred technical solution provides an installation method for the driving part and the clamping part, separating the driving part and the clamping part, which is convenient for their respective processing and forming. Moreover, the bearing is a common hardware part, which is convenient to purchase.
[0009] Preferably, the bearing is a one-way bearing. The advantage of this setting is that it can prevent the toothpaste tube from dropping when the user drives the body in the reverse direction, reducing the use efficiency.
[0010] Preferably, this technical solution further includes a return spring. The two ends of the return spring are respectively provided with a first foot and a second foot. The return spring is sleeved on the body. The body is provided with a first stop block, and the holding part is provided with a second stop block. When the return spring is in a relaxed state, the first foot contacts the first stop block, and the second foot contacts the second stop block; when the driving part drives the clamping part to rotate axially, the return spring is compressed. In this preferred technical solution, by setting the return spring, the body can return to its original position after completing the driving action, and then drive the handle to return to its original position after completing the driving action, so that the handle can always be in a convenient operating position.
[0011] Preferably, the holding part is provided with a limit pin, and the body is provided with a limit chute adapted to the limit pin. When the body drives the clamping part to rotate axially, the limit chute slides limitedly under the block of the limit pin to limit the axial rotation amplitude of the clamping part; alternatively, the holding part is provided with a limit chute, and the body is provided with a limit pin matching the limit chute. When the body drives the clamping part to rotate axially, the limit pin slides in the limit chute to limit the axial rotation amplitude of the clamping part. The advantage of this setting is that the limit pin and the limit chute cooperate with each other to control the rotation amplitude of the clamping part, avoiding excessive extrusion of toothpaste. In addition, the limited rotation can also prevent the return spring from being overcompressed and improve the service life of the return spring.
[0012] Preferably, the holding part includes an end cap. The end cap is provided with a groove, and the limit pin is in interference fit with the groove. In this preferred technical solution, the end cap can make the product more beautiful, and the limit pin also plays the role of fixing the end cap in this preferred technical solution, killing two birds with one stone.
[0013] Preferably, the return spring is arranged between the body and the end cap, and the second stop block is arranged on the end cap. The advantage of this setting is that if the return spring fails, the end cap can be directly removed for replacement.
[0014] Preferably, the holding part further includes a housing, and the clamping part is received in the housing. On the one hand, this makes the product more beautiful. More importantly, the driving part and the extrusion part are covered, improving the safety performance.
[0015] Preferably, the housing is provided with a gap through which the toothpaste tube filled with toothpaste can pass. The advantage of this setting is that the tail of the toothpaste tube is fixed in the clamping part, and the body of the toothpaste tube is also clamped by the gap, making the toothpaste squeezing operation more stable.
[0016] Preferably, the clamping part is provided with a long and narrow wavy notch. Compared with an ordinary long strip notch, the wavy notch increases the contact surface with the tail of the toothpaste tube, improving the clamping stability. The notch also facilitates the user to insert and remove the tail of the toothpaste tube.
[0017] Preferably, the holding part is provided with a card slot or a back glue sticking surface for external fixation.
[0018] Preferably, the extrusion part includes an elastic contact part. When the elastic contact part is in a relaxed state, the distance between the extrusion surface of the elastic contact part and the clamping part is less than twice the wall thickness of the toothpaste tube. The advantage of this setting is not only that the toothpaste can be squeezed out more cleanly, but also that it makes it possible to hang the toothpaste tube upside down. Once the toothpaste tube enters between the elastic contact part and the clamping part, it is tightly clamped and will not fall. At this time, it is more convenient to use the toothpaste tube upside down.
[0019] The effective effect of the present utility model is:
[0020] By providing a handle in the radial direction on the driving part body of the present utility model, the rotary extrusion is converted into a pressing extrusion, which is convenient for the user to use and avoids the problems of insufficient space of the knob and easy abrasion in the prior art.

Detailed implementation mode
[0030] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0031] Please refer to Figure 1 , Figure 2 and Figure 3 , this embodiment provides a toothpaste squeezing device, including a clamping part 2, a driving part 3 and a holding part 1. The driving part 3 is movably installed on the holding part 1. The driving part 3 includes a body 32 and a handle 321 fixed in the radial direction of the body 32. The handle 321 extends along the radial direction of the body 32 to the outside of the body. The body 32 is in transmission connection with the clamping part 2. When the body 32 rotates axially to drive the clamping part 2 to rotate axially, the toothpaste tube 5 clamped by the clamping part 2 generates extrusion with the extrusion part 12.
[0032] As Figure 3 shown, the holding part 1 is installed on the wall surface 6, the tail of the toothpaste tube 5 is fixed on the clamping part 2. The user pulls the handle 321 downward with one hand, the body 32 rotates axially. Since the body 32 is in transmission connection with the clamping part 2, it drives the clamping part 2 to rotate axially, and the toothpaste tube 5 rotates with the clamping part 2 to the extrusion part 12, and the toothpaste is extruded.
[0033] The connection mode between the body 32 and the clamping part 2 can be bearing connection, gear connection. The body 32 and the clamping part 2 can even be two parts of a single part, such as the handle and the pin body of a plug with a handle.
[0034] The length and shape of the handle 321 can be set according to needs, such as Figure 2 the spherical round rod shown, or in a flat sheet shape convenient for the user to press.
[0035] Based on the above toothpaste squeezing device, the present embodiment provides the following examples of specific implementable ways. On the premise of non-conflict, any combination can be made among the examples to form a new type of toothpaste squeezing device. It should be understood that any new type of toothpaste squeezing device formed by the combination of any examples shall fall within the protection scope of the present invention.
[0036] For example, as Figure 1 , Figure 4 , Figure 5 shown, the driving part 3 includes a main body 32 and a bearing 31. The holding part 1 has a fixing ring 11. The shaft body 325 of the main body 32 passes through the fixing ring 11 and is coaxially installed with the clamping part 2 through the bearing 31. The bearing can be a bidirectional bearing or a unidirectional bearing.
[0037] Furthermore, the bearing 31 is a unidirectional bearing. In this way, when the main body 32 rotates in a certain direction, the clamping part 2 is driven to rotate. When the main body 32 rotates in the opposite direction, the clamping part 2 will not have any reaction, which can prevent the toothpaste tube 5 from being lowered when the user drives the main body 32 in the reverse direction and reduce the use efficiency.
[0038] Furthermore, as Figure 1 , Figure 4 , Figure 7 shown, a return spring 4 is installed between the main body 32 and the holding part 1. The two ends of the return spring 4 are respectively provided with a first foot 41 and a second foot 42. The return spring 4 is sleeved on the column body 324 of the main body 32. The main body 32 is provided with a first stop block 323, and the holding part 1 is provided with a second stop block 132. When the return spring 4 is in a relaxed state, the first foot 41 contacts the first stop block 323, and the second foot 42 contacts the second stop block 132; when the driving part 3 drives the clamping part 2 to rotate axially, the return spring 4 is compressed. The return spring 4 can be installed between the fixing ring 11 and the main body 32, or can be installed between the main body 32 and the end cover 13 as shown in Figure 1 shown. In this way, as soon as the user releases the hand, the handle 321 can be reset, which is convenient for the next use.
[0039] In order to prevent the return spring 4 from being overcompressed, as Figure 6 shown, the fixing ring 11 is provided with a limit pin 111, and the main body 32 is provided with a limit chute 322 adapted to the limit pin 111. When the driving part 3 drives the clamping part 2 to rotate axially, the limit chute 322 slides limitedly under the block of the limit pin 111. Such a setting also has the advantage of the amount of toothpaste extruded at one time. Of course, in other embodiments, the limit pin can also be provided on the main body 32, and the limit chute can be provided on the fixing ring 11.
[0040] Again, for example, as Figure 2 and Figure 7As shown, the holding part 1 further includes an end cap 13. The end cap 13 is provided with a groove 131, and the limit pin 111 is in interference fit with the groove 131. The end cap 13 can make the product more beautiful. In this preferred technical solution, the limit pin 111 also plays the role of fixing the end cap 13 at the same time, killing two birds with one stone.
[0041] For another example, as Figure 1 and Figure 7 shown, the return spring 4 is located between the body 32 and the end cap 13. The second stop block 132 is provided on the end cap 13 to facilitate replacing the end cap 13 when the return spring 4 fails. Of course, in other embodiments, the spring can also be sleeved in the sandwich between the fixing ring 11 and the body 32. In this way, the limit pin 111 can also play the role of the second stop block 132.
[0042] For another example, as Figure 2 shown, the holding part 1 further includes a housing 14, and the clamping part 2 is received in the housing 14. Compared with the embodiment without the housing 14, in this way, the clamping part 2 and the pressing part 12 are enclosed, and the safety performance is higher.
[0043] For another example, as Figure 2 shown, the housing 14 is provided with a gap 141 for the toothpaste tube 5 filled with toothpaste to pass through. The head of the toothpaste tube 5 protrudes from the gap 141, and the tube body is clamped by the gap 141, improving the operation stability. In other embodiments, the gap 141 can also be not provided, so that the entire toothpaste tube 5 is received in the housing 14, achieving a hygienic effect.
[0044] For another example, as Figure 8 shown, the clamping part 2 is provided with a long and narrow wavy notch 21. Compared with an ordinary long strip-shaped notch, the wavy notch 21 increases the contact surface with the tail of the toothpaste tube, improving the clamping stability. The notch also facilitates the user to insert and remove the tail of the toothpaste tube 5. In other embodiments, the clamping part 2 can adopt various clamping forms such as a long straight notch, a wavy closed notch or a metal elastic sheet.
[0045] For another example, as Figure 2 shown, the holding part 1 is provided with a card slot 15 for external fixation. By pasting an upward plug on the wall, the holding part 1 can be fixed on the wall. Of course, other methods can also be used to fix the holding part 1 to the wall, such as direct pasting.
[0046] For another example, the pressing part 12 further includes an elastic contact part, and the elastic contact part can be a plastic elastic sheet as Figure 1 shown, or a metal elastic sheet, or an elastic rubber block, as Figure 4 and Figure 5When the plastic elastic piece is in a relaxed state, the distance between the extrusion surface of the plastic elastic piece and the clamping portion 2 is less than twice the wall thickness of the toothpaste tube 5. The advantage of such a setting is not only that the toothpaste can be squeezed out more cleanly, but also that it makes it possible to hang the toothpaste upside down. Once the toothpaste tube enters between the plastic elastic piece and the clamping portion 2, it will be tightly clamped and will not fall. At this time, it is more convenient to use the toothpaste upside down.
[0047] The present utility model is not limited to the above optional embodiments. Any person can obtain other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present utility model, they all fall within the protection scope of the present utility model.
