[0002] Dry eyes are caused by a variety of factors and are tear secretion disorders with dry eyes as the main symptom. Currently, the main treatment method is to instill eye drops for lubrication, which cannot promote the body's own tear secretion.

[0003] With the advancement of technology, a tear secretion promoting device disclosed in ZL202221207039.7 has appeared on the market. It drives the vibrator and the vibrating head to vibrate through the driving part inside the shell, and then the vibrating head extending out of the shell is pressed against the skin near the user's nasal bone and the outer nasal cartilage, so that the vibration can stimulate the external nasal nerves, thereby achieving the effect of promoting the body's tear secretion through the nasolacrimal reflex.

[0004] However, in such devices, the rigidity of the vibrator itself in the shell is fixed. After the vibrator is in close contact with the user, the vibration effect transmitted to the user by the motor through the vibrator and the vibrating head is also fixed. Some users with more sensitive extranasal nerves may feel uncomfortable when using such devices, while other users with insensitive extranasal nerves may find it difficult to achieve the effect of tear secretion when using such devices.

[0005] Therefore, the existing equipment has the problem that the vibration transmission effect is relatively fixed and it is difficult to meet the needs of patients with different physiques. Utility Model Content

[0006] The purpose of the utility model is to provide a tear secretion promoting instrument. The utility model has the advantages of being able to adjust the vibration transmission effect and meet the needs of patients with different physiques.

[0007] The technical solution of the utility model is as follows: a tear secretion promoting instrument comprises a shell; a vibration chamber is arranged in the shell, and a vibration rod is suspended in the vibration chamber; the bottom end of the vibration rod is connected to the shell, a vibration head extending out of the shell is arranged on one side of the top end of the vibration rod, and a vibration motor located in the shell is connected to the top of the vibration rod; a slide groove parallel to the vibration rod is arranged on the shell, a push block is slidably arranged in the slide groove, one end of the push block is located outside the shell, and the other end of the push block is connected to a slider slidably sleeved on the vibration rod.

[0008] In the aforementioned tear secretion promoting instrument, a shift plate is connected to the position on one side of the slider in the shell, and a plurality of shift slots are arranged at intervals on the shift plate; an elastic rod is arranged on the side of the slider facing the shift plate, and a shift block is arranged at the end of the elastic rod and protrudes into the shift slot.

[0009] In the aforementioned tear secretion promoting instrument, a slide rail is provided in the shell and is matched with the outer side of the slider, and the slide rail and the slide groove are arranged parallel to each other.

[0010] In the aforementioned tear secretion promoting instrument, a collar is provided at the bottom end of the vibration rod, and a connecting column fixed on the shell is sleeved inside the collar.

[0011] In the aforementioned tear secretion promoting instrument, the vibration motor is vertically arranged, and a horizontally arranged eccentric wheel is connected to the vibration motor.

[0012] In the aforementioned tear secretion promoting instrument, an installation cavity is provided in the shell, and a control board and a battery are connected in the installation cavity; a charging port and a button switch are connected to the side of the shell, and the button switch, charging port, battery and vibration motor are all electrically connected to the control board.

[0013] In the aforementioned tear secretion promoting instrument, the button switch is located on the top of the shell away from the vibration head.

[0014] In the aforementioned tear secretion promoting instrument, the installation cavity and the vibration cavity are respectively arranged on the left and right sides of the shell.

[0015] In the aforementioned tear secretion promoting instrument, a triangular supporting rib is provided on the vibration rod corresponding to the connection portion between the vibration rod and the vibration head.

[0016] In the aforementioned tear secretion promoting instrument, the shell is in the shape of a handle; a wavy gripping groove is provided on the side of the shell corresponding to the vibration head.

[0017] Compared with the prior art, the utility model connects the bottom end of the vibration rod to the shell, and provides a protrusion on one side of the top end of the vibration rod outside the shell, so that the vibration rod is suspended in the vibration cavity, and when the vibration motor vibrates, it can better drive the vibration rod to vibrate relative to the vibration cavity; the user can also push the push block to slide along the slide groove, so that the sliding block connected to the push block is sleeved outside the vibration rod and slides along the vibration rod, and the length of the suspended part on the top of the vibration rod is adjusted, thereby changing the rigidity of the vibration rod; when the vibration head contacts the user, the greater the rigidity of the vibration rod, the less the vibration rod buffers and absorbs the vibration energy generated by the vibration motor, and the better the transmission effect of the vibration energy to the user, which can meet the needs of users with low sensitivity; conversely, the smaller the rigidity of the vibration rod, the more the vibration rod buffers and absorbs the vibration energy generated by the vibration motor, and the weaker the transmission effect of the vibration energy to the user, which can meet the needs of users with low sensitivity.

[0018] In addition, the shift block at the top of the elastic rod on one side of the slider in the utility model can slide between multiple gear slots on the gear plate, and the gear adjustment can be achieved by inserting the shift block into the gear slots at different positions; when the shift block is inserted into the gear slot at the corresponding position, the slider is not easy to slide, and the vibration rod can transmit vibration under the corresponding rigidity of this part.

[0019] A slide rail for limiting the sliding of the slider is arranged in the shell. The sliding stability of the slider is high, and the matching stability between the slider and the shell is also high. The rigidity of the vibration rod can be better adjusted by the position of the slider on the vibration rod.

[0020] The bottom end of the vibration rod cooperates with the connecting column in the shell through the ring, so that there is a certain degree of rotational freedom between the bottom of the vibration rod and the shell, and the vibration motor can better drive the vibration rod to vibrate when it vibrates; the vibration generated when the vertically arranged vibration motor drives the horizontally arranged eccentric wheel at its top to rotate can better drive the vibration head to perform telescopic vibration relative to the shell.

[0021] The installation cavity and the vibration cavity are distributed on the left and right in the shell, and the vibration of the vibration rod in the vibration cavity is not easy to affect the parts in the installation cavity; a battery is arranged in the installation cavity, which can perform long-term wireless operation and is convenient to carry and use; when the user holds the card body, the thumb can directly press the button switch on the top of the shell, thereby realizing a more convenient one-handed switch operation; and the shell is in the shape of a handle, and a wavy gripping groove is also arranged on one side of the shell corresponding to the vibration head, which is more ergonomically designed and more comfortable when held in hand.

[0022] The triangular supporting ribs at the connection between the vibration rod and the vibration head can strengthen the connection strength at this part with less material and enable the vibration of the vibration rod to be better transmitted to the vibration head.

[0023] Therefore, the utility model can not only adjust the vibration transmission effect to meet the needs of patients with different physiques, but also has the advantages of convenient gear adjustment, easy carrying and use, high structural stability and comfortable operation.

An installation cavity 17 is provided, and a control board 18 and a battery 19 are connected to the installation cavity 17; a charging port 20 and a button switch 21 are connected to the side of the shell 1, and the button switch 21, the charging port 20, the battery 19 and the vibration motor 5 are all electrically connected to the control board 18; the button switch 21 is located at the top of the shell 1 away from the vibration head 4; the installation cavity 17 and the vibration cavity 2 are respectively arranged on the left and right sides of the shell 1; a triangular support rib 22 is provided on the vibration rod 3 corresponding to the connection position between it and the vibration head 4; the shell 1 is in the shape of a handle; a wavy gripping groove 23 is provided on the side of the shell 1 corresponding to the vibration head 4.

[0034] Working principle: The user grasps the handle-shaped housing 1, with four fingers located at the wave-shaped grasping groove 23, and the thumb located at the button switch 21 at the top of the housing 1; the user has a high gripping comfort and can control the button switch 21 with the thumb to give a switch signal to the control panel 18.

[0035] After the user presses the button switch 21 with his thumb, the control panel 18 receives the signal to control the battery 19 to supply power to the vibration motor 5, and the vertical vibration motor 5 drives the eccentric wheel at the top thereof to rotate and generate vibration; since the vibration motor 5 is connected to the top of the vibration rod 3, the vibration of the vibration motor 5 can drive the vibration rod 3 and the vibration head 4 connected to the vibration rod 3 to vibrate. Subsequently, the user can bring the vibration head 4 extending out of the housing 1 close to the skin near the nasal bone and the lateral nasal cartilage, and the vibration on the vibration head 4 can stimulate the external nasal nerve, thereby achieving the effect of promoting the secretion of human tears through the nasolacrimal reflex.

[0036] If the user needs to improve the vibration feeling, he can push the push block 7 to move upward along the slide groove 6, so that the slider 8 connected to the push block 7 is sleeved on the outside of the vibration rod 3 and slides upward, which can reduce the suspended length of the top of the vibration rod 3 in the vibration cavity 2, increase the rigidity of the part of the vibration rod 3 located above the slider 8, and the vibration rod 3 buffers and absorbs the vibration energy generated by the vibration motor 5 to reduce, and the vibration energy transmission effect is improved, thereby improving the vibration feeling of the user; if the user needs to reduce the vibration feeling, he can push the push block 7 to move downward along the slide groove 6, so that the slider 8 connected to the push block 7 is sleeved on the outside of the vibration rod 3 and slides downward, which can increase the suspended length of the top of the vibration rod 3 in the vibration cavity 2, thereby weakening the rigidity of the part of the vibration rod 3 located above the slider 8, and the vibration rod 3 buffers and absorbs the vibration energy generated by the vibration motor 5 to increase, and the vibration energy transmission effect is weakened, thereby reducing the vibration feeling of the user.

[0037] When the slider 8 slides along the vibration rod 3, the outer side of the slider 8 can slide along the slide rail 13 in the housing 1, and the overall sliding stability is high. The slider 8 can better limit the part of the vibration rod 3 set in the slider 8 through the housing 1, so as to better adjust the rigid gear position of the vibration rod 3. When the gear position is adjusted by the push block 7, the shift block 12 at the end of the elastic rod 11 on one side of the slider 8 can slide out from the gear slot 10 on the gear plate 9 and slide into the gear slot 10 on the upper or lower side of the gear slot 10; when the vibration motor 5 drives the vibration rod 3 to vibrate, the slider 8 will not slide randomly, and the vibration transmission effect of each gear position is relatively stable.

[0038] The bottom end of the vibration rod 3 cooperates with the connecting column 15 in the housing 1 through the collar 14, so that there is a certain degree of rotational freedom between the bottom of the vibration rod 3 and the housing 1, and the vibration motor 5 can better drive the vibration rod 3 to vibrate when vibrating; the vibration generated when the vertically arranged vibration motor 5 drives the eccentric wheel arranged horizontally at its top to rotate can better drive the vibration head 4 to perform telescopic vibration relative to the housing 1. A triangular support rib 22 is provided at the connection between the vibration rod 3 and the vibration head 4, so that this part can provide a higher connection strength with less material, and the vibration of the vibration rod 3 can be better transmitted to the vibration head 4.
