[0036] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] Please refer to Figures 1 to 3 The present utility model embodiment provides a handle 10, the handle 10 comprises:

[0038] The main body 100 has a first groove 140 disposed at one end thereof;

[0039] The sealing member 300 is connected to the main body 100 and is located in the first groove 140 , and forms an installation gap 101 with the inner wall of the first groove 140 ;

[0040] The needle tube 200 is sleeved on the sealing member 300, has an interference fit with the sealing member 300, and is located in the installation gap 101;

[0041] The seal 300 and the main body 100 are respectively provided with a first channel 301 and a second channel 102 , the two ends of the first channel 301 are respectively connected to the needle tube 200 and the second channel 102 , and the end of the second channel 102 away from the first channel 301 is connected to the external environment.

[0042] In this embodiment, the channel includes a first channel 301 and a second channel 102. Figure 2 The direction indicated by the dotted arrow is the flow direction of the liquid in the channel. As can be seen from the arrow, during the flow of the liquid, due to the interference fit between the seal 300 and the needle tube 200, the gap at the connection between the seal 300 and the needle tube 200 is small, and the liquid cannot leak from the connection between the two, and the overall sealing of the handle 10 is high. At the same time, when installing the handle 10, the needle tube 200 can be connected to the main body 100 by sleeve-mounting the needle tube 200 on the seal 300 and inserting it into the installation gap 101. In summary, the handle 10 of the embodiment of the utility model has high assembly efficiency and can prevent liquid leakage.

[0043] It should be understood that the interference fit between the seal 300 and the needle tube 200 may be that the size of the seal 300 is larger than that of the needle tube 200, or that other structures are filled between the seal 300 and the needle tube 200. The seal 300 may be a needle tube plug.

[0044] Furthermore, the handle 10 also includes a filling piece (not shown in the figure), which is located in the installation gap 101 and between the needle tube 200 and the inner wall of the first groove 140 .

[0045] In this embodiment, a filling piece is provided between the inner wall of the first groove 140 and the needle tube 200, and the filling piece can further block the installation gap 101 and form a squeezing effect on the connection between the sealing piece 300 and the needle tube 200, thereby improving the sealing between the sealing piece 300 and the needle tube 200, and the needle tube 200 and the main body 100. In summary, the filling piece of this embodiment can further improve the sealing of the handle 10.

[0046] Furthermore, the filling piece is a two-liquid hardening adhesive layer.

[0047] In this embodiment, the two-liquid hardened rubber layer has high bonding strength, flexibility and plasticity. Since most of the needle tube 200 are elastic parts, it is impossible to use rigid connection methods such as threaded connection and snap connection to achieve the connection between the needle tube 200 and the main body 100. Therefore, when the filling piece is a two-liquid hardened rubber layer, it can not only further improve the sealing of the handle 10 and prevent the handle 10 from leaking, but also connect the needle tube 200 and the main body 100.

[0048] Furthermore, the handle 10 further includes a first sealing ring 510 , which is sleeved on an end of the sealing member 300 away from the main body 100 and abuts against the needle tube 200 .

[0049] In this embodiment, the first sealing ring 510 abuts the needle tube 200 from the axis outward, thereby achieving an interference fit between the sealing member 300 and the needle tube 200, and because the first sealing ring 510 abuts against the needle tube 200, the sealing performance between the needle tube 200 and the inner wall of the first groove 140 can also be improved. Compared with the solution of designing the diameter of the sealing member 300 to be larger than the inner diameter of the needle tube 200, the first sealing ring 510 in this embodiment can reduce the production cost of the sealing member 300. In summary, this embodiment can reduce the production cost of the handle 10, and improve the sealing performance between the sealing member 300 and the needle tube 200, and between the needle tube 200 and the main body 100.

[0050] Furthermore, along the direction from the groove bottom to the groove opening of the first groove 140 , the sealing member 300 is provided with a plurality of annular grooves 320 ;

[0051] There are multiple first sealing rings 510 , which are sleeved in the annular groove 320 in a one-to-one correspondence.

[0052] If the first sealing ring 510 slides during operation of the handle 10 , a small gap may appear between the first sealing ring 510 and the needle tube 200 , thereby causing liquid to leak from between the first sealing ring 510 and the needle tube 200 .

[0053] In this embodiment, the annular groove 320 can fix the position of the first sealing ring 510, thereby preventing the first sealing ring 510 from sliding axially along the seal 300. At the same time, the cooperation of multiple annular grooves 320 and multiple first sealing rings 510 can improve the sealing between the seal 300 and the needle tube 200 at multiple levels, further preventing liquid leakage.

[0054] Furthermore, the sealing member 300 is threadedly connected to the main body 100 , and the sealing member 300 is provided with at least two first gripping surfaces 310 facing the inner wall of the first groove 140 , and the two corresponding first gripping surfaces 310 are parallel to each other.

[0055] In this embodiment, since the seal 300 and the main body 100 are threadedly connected, when assembling the seal 300 and the main body 100, the seal 300 or the main body 100 needs to be rotated. Since the main body 100 is relatively large, the seal 300 is designed to rotate to complete the threaded connection between the main body 100 and the seal 300. At this time, since the seal 300 is provided with two mutually parallel first gripping surfaces 310, and the first gripping surfaces 310 face the inner wall of the first groove 140, the first gripping surfaces 310 can be clamped by a clamp, thereby driving the seal 300 to rotate to complete the threaded connection with the main body 100. In summary, the first gripping surface 310 of this embodiment can provide a gripping position when the clamp is clamped, thereby facilitating the relative rotation between the seal 300 and the main body 100 to complete the connection.

[0056] Further, the main body 100 includes a first main body 110, a second main body 120 and a third main body 130 which are threadedly connected in sequence, the first groove 140 is provided in the third main body 130, and the sealing member 300 is provided through the second main body 120 and the third main body 130;

[0057] The first body 110 is provided with a connecting portion, which passes through the sealing member 300 and is located at one end inside the second body 120. The handle 10 further includes a second sealing ring 520, which is sleeved on the connecting portion.

[0058] If the main body 100 is an integrally formed structure, its production cost is relatively high because it needs to be provided with components or structures such as buttons, control components, water pipe connectors 400 and channels 20. At the same time, if the main body 100 is an integrally formed structure, it will also cause the internal components of the main body 100 to be difficult to disassemble, thereby resulting in low maintenance efficiency of the handle 10.

[0059] In this embodiment, firstly, since the main body 100 is divided into three parts, when it is necessary to install the components inside the main body 100, the components can be installed on the first main body 110, the second main body 120, and the third main body 130 first, and then the three parts of the main body 100 can be assembled, thereby improving the assembly efficiency of the handle 10. When disassembling the components inside the main body 100, the internal components can be removed and replaced by separating the second main body 120 and the third main body 130, and then disassembling them. Secondly, the connecting part, as a part of the third main body 130, is inserted into the sealing member 300. At this time, a channel 20 is formed in the third main body 130 and the sealing member 300. In order to prevent leakage of the channel 20, the second sealing ring 520 of this embodiment can prevent the liquid from flowing out of the channel 20, thereby improving the airtightness of the handle 10.

[0060] It should be understood that the connection between the first body 110, the second body 120 and the third body 130 can be a threaded connection, a snap-on connection, etc. The surface of the seal 300 facing the inner wall of the first groove 140 and the connection between the third body 130 and the second body 120 can be provided with threads. In this case, the second body 120 and the third body 130 can be simultaneously threadedly connected to the seal 300, that is, the seal 300 serves as an intermediate connector 400 to simultaneously connect the second body 120 and the third body 130. This connection method makes the seal 300 highly stable and not easy to fall off. The water path of the handle 10 of this embodiment is as follows: Figure 2 As shown, the liquid can enter the first body from the lower end of the first body 110 from bottom to top, and enter the connecting piece 400, and move to the sealing piece 300 along the dotted arrow through the lower end of the connecting piece 400, and then enter the second channel 102 formed by the main body 100 through the first channel 301 in the sealing piece 300, and finally enter the needle tube through the second channel 102, and then flow out of the needle tube.

[0061] Furthermore, the handle 10 further includes a connecting member 400, which is disposed through the first body 110 and is threadedly connected to the first body 110, and is used to connect a water pipe, and includes a first sub-connecting member 410 and a second sub-connecting member 420 connected to each other, and the first sub-connecting member 410 is threadedly connected to the first body 110;

[0062] The second sub-connector 420 is provided with a plurality of second gripping surfaces 430 , and two corresponding second gripping surfaces 430 are parallel to each other and face the inner wall of the first body 110 .

[0063] In this embodiment, first, the handle 10 needs to be connected to the water pipe so that the liquid can enter the handle 10. The connector 400 can play the role of connecting the water pipe. At the same time, the connector 400 is inserted into the first body 110, so the liquid flowing out of the connector 400 directly enters the seal 300 through the connection portion. Compared with the method of using the connector 400 to penetrate the seal 300, the connector 400 of this embodiment can avoid affecting the seal 300 when disassembling and replacing the connector 400, thereby causing the seal 300 to shake and affect the sealing of the handle 10. At the same time, it can also avoid the need to install the seal 300 first when installing the connector 400, which affects the overall installation efficiency of the handle 10.

[0064] Secondly, the connection member 400 and the first body 110 are connected by threads, so a clamp is needed to rotate the connection member 400. The second gripping surface 430 in this embodiment can be gripped by the clamp, thereby improving the installation efficiency of the connection member 400 and the first body 110. It should be understood that the connection member 400 can be a nozzle.

[0065] Furthermore, the first body 110 is provided with a second groove 150, the notch of the second groove 150 faces the side away from the first groove 140, and the groove bottom of the second groove 150 is provided with a third groove 160;

[0066] The handle 10 further includes a third sealing ring 530, which is sleeved on the first sub-connector 410 and located at one end where the second sub-connector 420 is located;

[0067] The first sub-connector 410 passes through the bottom of the second groove 150 , and the second sub-connector 420 abuts against the bottom of the second groove 150 , and presses the third sealing ring 530 into the third groove 160 .

[0068] In this embodiment, the second groove 150 can accommodate the connector 400. At the same time, since the connector 400 needs to be threadedly connected to the first body 110, the first sub-connector 410 cannot be provided with a sealing ring, and the handle 10 has a risk of leakage. Therefore, in this embodiment, a third sealing ring 530 is provided at the connection between the first sub-connector 410 and the second sub-connector 420, and the third sealing ring 530 is accommodated by the third groove 160, and the third sealing ring 530 is sealed by the second sub-connector 420, that is, the fixing component of the third sealing ring 530 is omitted. Therefore, when installing the connector 400 and the third sealing ring 530, the third sealing ring 530 can be placed in the third groove 160, and then the connector 400 is inserted into the second groove 150, so that after the first sub-connector 410 is threadedly connected to the first body 110, the second sub-connector 420 will naturally complete the fixing of the third sealing ring 530.

[0069] In summary, the handle 10 of this embodiment omits the installation structure of the third sealing ring 530, thereby improving the assembly efficiency of the handle 10 and reducing the production cost. At the same time, the handle 10 has high sealing performance.

[0070] Correspondingly, the present application also provides a medical device, which includes the handle 10 of any one of the above embodiments.

[0071] In this embodiment, in the handle 10 of the medical device, since the seal 300 and the needle tube 200 are interference fit, the gap at the connection between the seal 300 and the needle tube 200 is small, and liquid cannot leak from the connection between the two, and the handle 10 has high overall sealing. At the same time, when installing the handle 10, it is only necessary to sleeve the needle tube 200 on the seal 300 and insert it into the installation gap 101 to achieve the connection between the needle tube 200 and the main body 100. In summary, the medical device of the embodiment of the utility model has high assembly efficiency and can prevent liquid leakage.

[0072] Furthermore, the medical device also includes a tooth cleaner, a connecting line and a water pipe, wherein the tooth cleaner is used to store liquid and drive the liquid to flow, one end of the water pipe is connected to the tooth cleaner, and the other end is connected to the handle 10;

[0073] The connecting line is passed through the water pipe, one end of which is connected to the tooth cleaner, and the other end of which is connected to the handle 10, and the length of the connecting line is shorter than the length of the water pipe.

[0074] In this embodiment, when the handle 10 is in use, the handle 10 may be pulled, causing the connection between the water pipe and the tooth cleaner or between the water pipe and the handle 10 to be disconnected, thereby causing liquid leakage. In this embodiment, a connecting wire is passed through the water pipe, with one end connected to the tooth cleaner and the other end connected to the handle 10, so that the connecting wire can play a role in strengthening the overall strength of the medical device and avoid directly pulling and breaking the water pipe; at the same time, because the length of the connecting wire is shorter than the length of the water pipe, the connecting wire will be the main force object during the use of the handle 10, and the water pipe will only be subjected to the pulling force after the connecting wire is broken or extended.

[0075] In summary, the medical device of this embodiment has a strong sealing property, and it is not easy for the connection between the water pipe and the toothbrush or between the water pipe and the handle 10 to be disconnected, resulting in leakage.
