[0034] Referring to Figures 1 to 5 , the present invention provides an oral sprayer, which includes a housing assembly 206, an electronic control module 203, an atomization sheet 207, a liquid storage bottle 202, and a sliding cover 101.

[0035] Referring to Figure 1 and Figure 2 , the housing assembly 206 includes a top cover 102 and a bottom case 201. The interior of the bottom case 201 has an installation cavity 205, and both the electronic control module 203 and the atomization sheet 207 are installed in the installation cavity 205. The top cover 102 is connected to the bottom case 201 (specifically, they can be snap-connected to each other, and the corresponding snap-connection structure is not specifically shown), and the top cover 102 covers the opening of the installation cavity 205 to close the installation cavity 205. The top cover 102 is provided with a spray port 103 through which the liquid mist can be ejected. In some embodiments, the housing assembly 206 further includes an outer shell 104, the outer shell 104 is connected to the top cover 102 (similarly, it can be connected by snap connection, and the snap-connection structure is not specifically shown), the bottom case 201 is located inside the outer shell 104, and the outer shell 104 is used to protect the core components in the oral sprayer and at the same time make the overall appearance of the oral sprayer relatively smooth and flat, facilitating the user to hold.

[0036] Referring to Figure 2, the liquid storage bottle 202 is connected to the bottom shell 201. The liquid storage bottle 202 is used to store the liquid to be ejected, and the liquid storage bottle 202 is connected to the liquid output end of the atomization sheet 207. The liquid output end of the atomization sheet 207 faces the spray port 103. The central area of the bottom surface of the atomization sheet 207 is its liquid input end, and the central area of the top surface of the atomization sheet 207 is its liquid output end. The atomization sheet 207 can be set as the atomization sheet 207 or the micro-hole atomization sheet 207, and its specific structure and atomization principle belong to the well-known technology and will not be introduced in detail here. The electronic control module 203 includes a control switch 204. The control switch 204 is electrically connected to the atomization sheet 207, and the control switch 204 is used to control the start and stop of the atomization sheet 207.

[0037] Referring to Figure 4 and Figure 5 , the top cover 102 includes a locking body 403, and the top cover 102 is also provided with a first sliding groove 401. The locking body 403 includes a first protrusion 503, a second protrusion 505 and an extension 504. The two sides of the first sliding groove 401 are respectively a first side wall 501 and a second side wall 502; the first protrusion 503 is connected to the first side wall 501, and the first protrusion 503 protrudes towards the second side wall 502; the extension 504 is connected to the protruding end of the first protrusion 503, and both ends of the extension 504 extend in the length direction of the first sliding groove 401; the second protrusion 505 is connected to the end of the extension 504, and the second protrusion 505 protrudes towards the second side wall 502.

[0038] Referring to Figure 3 , the sliding cover 101 includes a first sliding body 301. The first sliding body 301 is slidably disposed in the first sliding groove 401. More specifically, the first sliding body 301 is slidably disposed in the gap between the extension 504 and the second side wall 502, and the gap between the extension 504 and the first side wall 501 serves as a space for the extension 504 to bend and deform. Taking Figure 1 and Figure 5 as an example, when the sliding cover 101 slides to the right end of the top cover 102 (that is, when the sliding cover 101 slides to abut against the right end of the top cover 102), the first sliding body 301 is located at the right end in the first sliding groove 401 and is located at the first position 506. At this time, the sliding cover 101 completely covers the spray port 103; when the sliding cover 101 slides to the left end of the top cover 102, the first sliding body 301 is located at the left end in the first sliding groove 401 and is located at the second position 507. At this time, the spray port 103 is completely exposed, and at the same time, the sliding cover 101 triggers the control switch 204 for controlling the start and stop of the atomization sheet 207 in the electronic control module 203, turns on the atomization sheet 207, and the oral sprayer starts to spray.

[0039] Referring to Figure 5, the following takes the process of the first sliding body 301 moving from left to right over the second protruding portion 505 on the right side to the first position 506 as an example to introduce the matching relationship between the locking body 403 and the first sliding body 301. After the first sliding body 301 moves to abut against the second protruding portion 505, due to the user's continuous application of force to the sliding cover 101, the extension portion 504 will bend toward the first side wall 501 to drive the second protruding portion 505 to move a short distance toward the first side wall 501, increase the distance between the second protruding portion 505 and the second side wall 502, so that the first sliding body 301 moves over the second protruding portion 505 to the first position 506. After the first sliding body 301 enters the first position 506, without applying external force to the sliding cover 101, the first sliding body 301 will be blocked by the second protruding portion 505 and cannot leave the first position 506. The oral sprayer provided by the present invention has a simple and reliable structure of the locking body 403, which can effectively limit the first sliding body 301, thereby limiting the sliding cover 101. Compared with some locking structures relying on elastic springs, the locking body 403 of the present invention is not easy to be damaged and has a long service life.

[0040] Reference Figure 3 The sliding cover 101 further includes a second sliding body 302, and the housing assembly 206 further includes a second sliding groove 402. The extension direction of the second sliding groove 402 is the same as the extension direction of the first sliding groove 401, and the second sliding body 302 is slidably disposed in the second sliding groove 402. The sliding fit between the second sliding body 302 and the second sliding groove 402 guides the sliding of the sliding cover 101. In addition, in some embodiments, the second sliding body 302 also prevents the sliding cover 101 from separating from the top cover 102. Figure 3 The side of the second sliding body 302 is hook-shaped, and the second sliding body 302 can hook the top cover 102 to prevent the sliding cover 101 and the top cover 102 from separating from each other in the up and down directions. The structure of the first sliding body 301 can be set relatively simple, for example, the first sliding body 301 is set to be cylindrical. Figure 1 In some embodiments, a finger groove 106 is provided on the first side surface of the sliding cover 101 facing away from the first sliding groove 401, and the bottom wall of the finger groove 106 is an arc surface, so that the user's finger (specifically, the finger pulp) can be pressed into the finger groove 106 and then push the sliding cover 101. The provision of the finger groove 106 can effectively reduce the situation where the finger slips on the sliding cover 101.

[0041] In some embodiments, the control switch 204 of the electronic control module 203 is set as a touch-type mechanical switch. When the sliding cover 101 touches the control switch 204, the control switch 204 is in the "on" state, and the atomizing sheet 207 is turned on and sprays; when the sliding cover 101 does not abut against the control switch 204, the control switch 204 is in the "off" state, and the atomizing sheet 207 is turned off. Specifically, the first sliding body 301 or the second sliding body 302 in the sliding cover 101 can be used to touch the control switch 204, so that there is no need to provide other structures on the sliding cover 101 for touching the control switch 204, which is beneficial to simplifying the structure of the sliding cover 101. If the first sliding body 301 is used to touch the control switch 204, the control switch 204 is arranged below one end of the first sliding groove 401. The lower end of the first sliding body 301 passes through the first sliding groove 401 from top to bottom and extends downward. When the first sliding body 301 moves to the corresponding end of the first sliding groove 401, the lower end of the first sliding body 301 abuts against the control switch 204. Similarly, if the second sliding body 302 is used to touch the control switch 204, the control switch 204 is arranged below one end of the second sliding groove 402 (reference can be made to Figure 4 ), which will not be described in detail here. In some other embodiments, the control switch 204 can also be set as a Hall switch. For example, a magnet is installed at the left end of the sliding cover 101, and the control switch 204 is correspondingly located at the left end of the installation cavity 205. When the sliding cover 101 slides to the left end of the top cover 102, the control switch 204 is in the magnetic field of the magnet, and the control switch 204 is turned on. Relatively speaking, setting the control switch 204 as a touch-type mechanical switch is beneficial to improving the sensitivity and response speed of the control switch 204.

[0042] In some embodiments, when the power of the electronic control module 203 is insufficient, the atomizing sheet 207 will not be turned on even after the control switch 204 is turned on. Moreover, to prevent the liquid in the liquid storage bottle 202 from being consumed too quickly at one time, the oral sprayer is configured such that the atomizing sheet 207 will turn off after being turned on for several seconds. At this time, the control switch 204 needs to be turned on again (for example, when the second slider 302 is separated from the control switch 204 and then touches the control switch 204 again) to perform the next spray. When the spray port 103 is exposed and no liquid mist is ejected, the user cannot quickly determine whether it is due to insufficient power or because the single spray time has elapsed and no liquid mist is ejected. To solve this problem, in some embodiments, the electronic control module 203 includes an indicator light (the indicator light is not specifically shown). The indicator light is located below the second sliding groove 402. When the power of the electronic control module 203 is sufficient, the indicator light is in a constantly lit state, or the indicator light is electrically connected to the control switch 204, and the indicator light emits light only when the control switch 204 is in the open state. The sliding cover 101 is provided with a first light-transmitting hole 303. When the sliding cover 101 slides to a position where it can turn on the control switch 204, the first light-transmitting hole 303 moves above the second sliding groove 402, and the light of the indicator light can pass through the second sliding groove 402 and the first light-transmitting hole 303 in sequence and be emitted. The user can determine the reason for the lack of liquid mist ejection by whether they can see the light of the indicator light, and select corresponding measures according to the specific reason (such as charging the oral sprayer or turning on the control switch 204 again).

[0043] Referring to Figure 4 、 Figure 6 and Figure 7 , in some embodiments, a second light-transmitting hole 404 can also be provided on the top cover 102. When the sliding cover 101 slides to the leftmost end, the second light-transmitting hole 404 on the top cover 102 and the first light-transmitting hole 303 on the sliding cover 101 are aligned in the up-down direction, and the light of the indicator light passes through the second light-transmitting hole 404 and the first light-transmitting hole 303 in sequence and is emitted. Relatively speaking, using the second sliding groove 402 to allow the light of the indicator light to pass through the top cover 102 does not require an additional hole to be opened on the top cover 102, reducing the processing complexity of the top cover 102; while opening an additional hole on the top cover 102 is beneficial to improving the layout flexibility of the indicator light. In addition, during the use of the oral sprayer, the spray port 103 and the upper surface of the sliding cover 101 usually face the user's oral cavity. Therefore, setting the first light-transmitting hole 303 on the sliding cover 101 makes it easier for the user to observe the light of the indicator light. It should be noted that if the light of the indicator light passes through the first light-transmitting hole 303 and the second sliding groove 402 and is emitted, the specific position of the first light-transmitting hole 303 is different from that shown in Figure 6 and Figure 7 , and adjustments need to be made to cooperate with the position of the second sliding groove 402. For example, the first light-transmitting hole is provided on the left side of the finger groove 106.

[0044] Reference Figure 8 , in some embodiments, the liquid storage bottle 202 includes a bottle body 801, an elastic member 803 and a liquid absorption rod 802. The interior of the bottle body 801 has a liquid storage cavity 806 for accommodating the liquid to be ejected, as well as for accommodating a part of the liquid absorption rod 802 and the elastic member 803. The liquid absorption rod 802 may specifically be a sponge rod. When the liquid volume is sufficient, at least a part of the liquid absorption rod 802 is immersed in the liquid, and the liquid absorption rod 802 can absorb the liquid. One end of the elastic member 803 is connected to the bottom end of the liquid absorption rod 802, and the other end of the elastic member 803 abuts against the bottom wall of the liquid storage cavity 806. The bottle body 801 further includes a connection portion 804. Both the connection portion 804 and the bottom case 201 have threads, and the connection portion 804 and the bottom case 201 are connected by threads. The connection portion 804 is provided with a bottle mouth 805, and the bottle mouth 805 can be used as the inlet of the liquid when adding liquid to the liquid storage cavity 806. The top end of the liquid absorption rod 802 can extend out of the liquid storage cavity 806 through the bottle mouth 805 and abut against the liquid input end of the atomization sheet 207. The atomization sheet 207 can atomize and eject the liquid at the top end of the liquid absorption rod 802. Since the volume of the liquid absorption rod 802 will increase after absorbing the liquid, the gap between the outer surface of the liquid absorption rod 802 and the side wall of the bottle mouth 805 decreases, and the liquid is less likely to leak from the bottle mouth 805. After the liquid storage bottle 202 is connected to the bottom case 201, the elastic member 803 is in a compressed state. Therefore, the liquid absorption rod 802 has a tendency to move upward under the elastic force of the elastic member 803, so that the top end of the liquid absorption rod 802 remains in contact with the atomization sheet 207, thus ensuring the stability of liquid supply.

[0045] Reference Figure 8 and Figure 9 , in some embodiments, the oral sprayer further includes a sealing member 901. The sealing member 901 can be made of rubber or silica gel. The sealing member 901 wraps the edge of the ultrasonic atomization sheet 207. After the connection portion 804 is connected to the bottom case 201, the top surface of the connection portion 804 presses the bottom surface of the sealing member 901 from bottom to top, thereby preventing the liquid flowing out or overflowing from the bottle mouth 805 from leaking. After the top cover 102 is connected to the bottom case 201, the top cover 102 can press the top surface of the sealing member 901 to prevent the ejected liquid mist from entering the housing through the gap between the top cover 102 and the bottom case 201, reducing the risk of short circuit of the electronic control module 203 in the oral sprayer.

[0046] Reference Figure 10, in some embodiments, the top cover 102 further includes a lanyard hook 105 located at the edge of the top cover 102. The lanyard hook 105 bends towards the outer surface of the bottom shell 201, so as to form a rope-passing space 1001 for a rope to pass through between the lanyard hook 105 and the outer surface of the bottom shell 201. The lanyard hook 105 hooks the rope to connect the rope to the oral sprayer, and the rope can be hung around the user's neck. The provision of the lanyard hook 105 increases the portability of the oral sprayer. Refer to Figure 11 , the outer shell 104 is further provided with a notch 1101. After the outer shell 104 is connected to the top cover 102, the lanyard hook 105 is accommodated in the notch 1101. The wall surface of the notch 1101 and the lanyard hook 105 will restrict the position and movement of the rope, preventing the rope from detaching from the oral sprayer, thereby increasing the connection reliability between the rope and the oral sprayer.

[0047] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
