All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1 to 24, in an embodiment of the present invention, an oral cavity sprayer for convenient starting includes a main body 10, a liquid bin 20, an atomizing assembly 30, a power supply assembly 50 and a control assembly 60 are disposed in the main body 10, the liquid bin 20 is filled with a liquid to be atomized, the atomizing assembly 30 is used for atomizing and spraying the liquid to be atomized, the power supply assembly 50 provides operation power for the atomizing assembly 30 and the control assembly 60, and the control assembly 60 is used for driving and managing operation of the atomizing assembly 30; the atomizing assembly 30 is provided with an atomizing cover 32, an atomizing seat 40 and an atomizing sheet 31, the liquid bin 20 is connected to the atomizing seat 40, the atomizing sheet 31 is fixedly connected to the atomizing seat 40, and the atomizing cover 32 is positioned at the outermost side of the atomizing assembly 30 and covers the atomizing sheet 31 and the atomizing seat 40; the control assembly 60 is provided with a circuit board 61, a control chip and an induction device (not shown in the figure), the control chip and the induction device are respectively electrically connected with the circuit board 61, the induction device is arranged on the atomization cap 32 and is used for detecting touch operation of a user and transmitting corresponding signal data to the control assembly 60, and the control assembly 60 receives the signal data transmitted by the induction device and operates preset operation according to the signal data.

Specifically, the user moves the oral sprayer to the vicinity of the mouth and brings the skin of the mouth into contact with the atomizing base 40, so that the sensing device senses the touch of the skin, then sends a start signal to the control component 60, and after receiving the start signal, the control component 60 controls the atomizing component 30 to start the atomizing operation, and then sprays water mist from the spray outlet 34 of the atomizing base 40, so that the water mist is directly sprayed into the oral cavity of the user. Therefore, the spraying opening time of the mouth sprayer can be controlled more accurately, so that the mouth sprayer can accurately spray water mist into the oral cavity, misoperation is not easy to occur, liquid is not wasted, and other objects are not wetted.

In another embodiment, the sensing means is provided with sensing circuitry (not shown) for detecting a skin touch operation on the outer wall of the aerosol cap 32; the outer part of the main body 10 is provided with a conductive shell 13, and the atomization cap 32 is made of a conductive material; the induction circuit is provided with a conductive square 64 and a conductive terminal 65 which are respectively and electrically connected with the control component 60, the conductive square 64 is electrically connected with the shell 13 so as to provide power for the shell 13 and connect the shell 13 into the induction circuit, and the conductive terminal 65 is electrically connected with the atomization cap 32 so as to provide power for the atomization cap 32 and connect the atomization cap 32 into the induction circuit; the sensing device detects a skin touch operation on the outer wall of the atomizing cover 32 according to the conductive state of the sensing circuit.

Specifically, the housing 13 and the atomizing cover 32 of the oral sprayer are made of conductive materials by utilizing the conductive property of the skin of the human body, and the housing 13 and the atomizing cover 32 are respectively connected into the induction circuit by using the conductive square block 64 and the conductive terminal 65. When a user takes the oral sprayer, the hand skin of the user can contact the conductive shell 13, and then the oral sprayer is moved to a mouth position, so that the mouth skin is contacted with the conductive atomization cover 32, an electric loop is formed among the shell 13, the hand skin, the mouth skin and the atomization cover 32, the induction circuit is in a conducting state, and the induction device can send corresponding conducting signals to the control chip according to the conducting state of the induction circuit. Upon receiving the on signal, the control chip may control the atomizing assembly 30 to start, begin atomizing the liquid, and then spray the mist from the position of the spray outlet 34 of the atomizing cap 32.

In another embodiment, as shown in fig. 12, preferably, the sensing device is provided with a capacitive sensing touch key 69, and the touch key 69 is disposed on the inner wall of the aerosol cap 32 and can detect a skin touch operation on the outer wall of the aerosol cap 32; the atomization cap 32 is made of an insulating material having a certain thickness and capable of transmitting a skin touch operation.

Specifically, the thickness of the sidewall of the aerosol cap 32 is preferably set to be between 0.1 mm and 2.9 mm, so that skin touch on the outer wall of the aerosol cap 32 can be more effectively detected by the touch keys 69. Preferably, the atomizing cover 32 may be configured as a flat cylinder, and both sides of the flat cylinder are provided with capacitive sensing touch keys 69, and are electrically connected to the control assembly 60 respectively.

Secondly, a corresponding capacitive sensing touch key 69 may be directly disposed on the inner wall of the atomizing cover 32, one may be disposed on one side, or a plurality of capacitive sensing touch keys 69 may be disposed on multiple sides, and when only one capacitive sensing touch key 69 is disposed on one side, it will be understood that some prompts may be disposed on the corresponding side, so that a user may know the disposed position of the capacitive sensing touch key 69. For example, protrusions or recesses may be provided on the outer wall of the atomizing cover 32 to provide a cue. When the user moves the oral sprayer near the mouth and brings the mouth skin into contact with the outer wall of the atomization cap 32, the touch button 69 can detect the touch operation of the skin, so as to send a corresponding mouth skin touch signal to the control chip, and after the control chip receives the mouth skin touch signal, the control chip controls the atomization assembly 30 to start to atomize liquid, and then the water mist is sprayed from the position of the spray outlet 34 of the atomization cap 32.

In yet another embodiment, the control assembly 60 is further provided with a push button switch 66, the push button switch 66 being electrically connected to the circuit board 61 and controlling the operation of the atomizing assembly 30 to atomize the liquid into a mist for discharge.

Specifically, in order to take care of the conventional usage habits of the user, a corresponding push-button switch 66 may be provided, so that the oral cavity sprayer may be turned on and off correspondingly through the push-button switch 66. Such as double clicking on the push button switch 66 while remaining depressed, the oral sprayer begins to spray water mist. The holding state of the push button switch 66 is then released, i.e., the discharge of the mist is stopped. Preferably, a corresponding function of stopping the timing may be provided, such as stopping the continuous spraying of the water mist after the holding state of the oral sprayer is continued for five seconds, even if the holding state of the push button switch 66 is maintained. Thus preventing accidents or stopping spraying when the user forgets to release the push button switch 66.

In yet another embodiment, the push-button switch 66 is preferably configured as a capacitive sensing touch key 69, and when the push-button switch 66 detects a skin touch operation, a corresponding touch signal is sent to the control assembly 60.

Specifically, to optimize the use experience, the push switch may be used instead of the push switch, and the push switch 66 may be configured as a touch button 69, so that the push switch 66 may be triggered by touching the finger skin. In order to prevent false touches, it is preferable to provide a quick tap twice and hold the finger skin on the push button switch 66 before the corresponding start operation.

In yet another embodiment, it is preferred that the control assembly 60 not begin to activate operation of the atomizing assembly 30 until a skin touch signal is received from both the sensing device and the push button switch 66.

Specifically, as described above, even if the push switch 66 is provided as the capacitive sensing touch key 69, it is required to be provided as a double tap in order to prevent erroneous touch, which is inconvenient. Therefore, instead of touching twice, the user's finger skin is directly placed and held on the touch button 69 of the button switch 66, and then the atomizing cover 32 is contacted with the skin of the mouth, so that the touch button 69 on the atomizing cover 32 also detects the skin touch operation, and the control chip receives the skin touch signals of the sensing device and the button switch 66 at the same time, so as to control the atomizing assembly 30 to start the start operation. In this embodiment, when the push button switch 66 and the atomizing cover 32 use the touch keys 69 at the same time, the false touch can be prevented, the operation habit of the user can be met, and the use experience of the user can be improved.

As shown in fig. 13 to 14, the present invention further provides a method for starting an oral sprayer, the method comprising: detecting touch operation of a user on the oral sprayer to obtain corresponding signal data; comparing the corresponding signal data with preset information to determine whether to operate the atomizing assembly 30; generating a corresponding operation instruction according to the judging result; the atomizing assembly 30 is correspondingly operated according to the operation instructions.

Specifically, the oral sprayer is started directly in a touch manner, so that the use experience of a user is optimized, the problem that fingers are required to be pressed with force when a switch is pressed is avoided, and a certain pressing sound is generated is solved. The touch type touch screen can be quite silent relatively, can be started by touching lightly, is elegant and attractive in action, and brings a certain aesthetic feeling to people.

As shown in fig. 14, the method for detecting a touch operation includes: the induction circuit detects that the atomization cap 32 and the shell 13 form an electric loop, so that the induction circuit is in a conducting state, namely a corresponding conducting signal is sent.

As shown in fig. 15, the method for detecting a touch operation further includes: touch operation of the user's mouth skin on the atomizing cover 32 is detected by the capacitive sensing touch key 69, and a corresponding mouth touch signal is transmitted.

As shown in fig. 16, the method for detecting a touch operation further includes: touch operation of the user's hand skin on the push button switch 66 is detected by the capacitive sensing touch key 69, and a corresponding hand touch signal is transmitted.

As shown in fig. 17, the method for detecting a touch operation further includes: the touch operation of the user's mouth skin to the atomizing cover 32 and the touch operation of the user's hand skin to the button switch 66 are detected by the capacitive sensing touch key 69, respectively, and the corresponding mouth touch signal and hand touch signal are simultaneously transmitted.

Specifically, in this embodiment, the user only needs to place the skin of the handle portion on the button switch 66, and the touch key 69 on the button switch 66 can receive the finger touch operation, so as to send a corresponding hand touch signal; and simultaneously, the oral sprayer is moved to the position of the mouth, so that the skin of the mouth touches the touch key 69 on the atomization cap 32, the touch key 69 on the atomization cap 32 sends a corresponding mouth touch signal, and the control chip only receives the hand touch signal and the mouth touch signal at the same time for comparison. When the comparison parameters are consistent, the atomizing assembly 30 is started to perform corresponding liquid atomization and spray water mist. The comparison parameter may be the intensity of the touch signal, or the touch time, etc.

In yet another embodiment, referring to fig. 1 to 12, a convenient-to-start oral sprayer includes a main body 10, a liquid bin 20, an atomizing assembly 30, a power supply assembly 50 and a control assembly 60 are disposed in the main body 10, the liquid bin 20 is filled with liquid to be atomized, the atomizing assembly 30 is used for atomizing and spraying the liquid to be atomized, the power supply assembly 50 provides operation power for the atomizing assembly 30 and the control assembly 60, and the control assembly 60 is used for driving and managing operation of the atomizing assembly 30; the control assembly 60 is provided with a circuit board 61, a control chip (not shown in the figure) and an induction circuit (not shown in the figure), and the power assembly 50, the atomizing assembly 30, the control chip and the induction circuit are respectively and electrically connected to the circuit board 61; the outside of the main body 10 is provided with a conductive shell 13, the atomization assembly 30 is provided with a conductive atomization cap 32, the induction circuit is provided with a conductive square 64 and a conductive terminal 65, the conductive square 64 is electrically connected with the shell 13 so as to provide power for the shell 13 and connect the shell 13 into the induction circuit, and the conductive terminal 65 is electrically connected with the atomization cap 32 so as to provide power for the atomization cap 32 and connect the atomization cap 32 into the induction circuit; the control chip drives the atomizing assembly 30 to operate correspondingly according to the conduction state of the sensing circuit.

Specifically, first, an electronic oral sprayer, which is generally provided with a control switch (not shown), is used to control the opening of the oral sprayer, so that the liquid in the oral sprayer is atomized to form a mist, and the mist is sprayed into the oral cavity to perform corresponding treatments, such as freshening breath, relieving symptoms, and the like. Unlike conventional humidification sprayers, the requirements for spraying time are higher. Humidification sprayers are generally used for supplementing water to the surrounding environment or the surface skin, relatively do not need very accurate spraying time, and even some humidifiers which use a common water source as liquid to be atomized can be opened for a long time. However, electronic oral nebulizers are relatively expensive due to the limited volume of liquid within them, and generally are liquids having specific components, and waste should be avoided as much as possible. The opening time of the mouth sprayer is important, and it is preferable that the spraying function of the mouth sprayer is started after the discharge opening 34 of the atomizing cap 32 is placed at the corresponding portion of the mouth. However, the traditional switch is easy to cause misoperation such as advanced operation or delayed operation due to manual control of a user, and the situations of wasting liquid or wasting time and the like occur.

Secondly, in the embodiment, by arranging the corresponding sensing circuit, when the control chip detects that the sensing circuit is in a conducting state, the atomizing assembly 30 is started, so that liquid is atomized into water mist to be sprayed out; when the control chip detects that the sensing circuit is in a non-conducting state, the atomizing assembly 30 is turned off, and water mist is not sprayed. It will be appreciated that the time for continuously opening the atomizing assembly 30 may be limited, for example, the control chip may stop the atomizing assembly 30 from being opened after continuously opening the atomizing assembly 30 for five seconds even if the sensing circuit is still in the on state. The accident situation is prevented, and the sensing circuit is in an incorrect conduction state, so that the water mist is continuously sprayed. The control chip can adopt the existing products in the prior art to carry out corresponding production processing, so that the control chip can process the instructions. For example, an MCF73 singlechip, which is an existing product in the prior art, is used, and the 8-bit Flash universal MCU with high performance and low power consumption is provided.

The sensing circuit is preferably configured such that the atomizing cover 32 contacting the skin of the mouth and the housing 13 contacting the skin of the hand are connected to the sensing circuit, respectively, so that the user holds the housing 13 of the mouth sprayer and moves the mouth sprayer to a position close to the mouth, and the atomizing cover 32 contacts the skin of the mouth, whereby the sensing circuit can be electrically circulated, and the control chip can turn on the atomizing assembly 30 to perform the atomizing operation according to the on state of the electrically circulated circuit, thereby atomizing the liquid in the mouth sprayer into mist, and discharging the mist into the oral cavity. Therefore, the spray opening time of the mouth sprayer can be accurately controlled, so that the mouth sprayer can spray water mist into the oral cavity at proper time, and the situation of wasting liquid is avoided.

Again, preferably, the portion of the atomizing cover 32 corresponding to the conductive terminal 65 may further be provided with a second magnetic member 16, where the second magnetic member 16 is fixedly connected to the atomizing cover 32 and forms an adsorption connection with the conductive terminal 65, so that the atomizing cover 32 better forms an abutment with the conductive terminal 65, thereby forming an electrical connection. Preferably, the second magnetic member 16 may be in contact with the conductive terminal 65 or in contact with the atomizing cover 32, and therefore the second magnetic member 16 may be a conductive metal magnetic member having a magnetic force, so that the conductive terminal 65 may be adsorbed, or the atomizing cover 32 and the conductive terminal 65 may be directly and electrically connected.

As shown in fig. 1, preferably, the main body 10 is further provided with an outer cover 11, and the outer cover 11 is connected to one end of the main body 10 in a buckling manner and forms a cover for the atomizing assembly 30; the outer cover 11 is provided with a first magnetic member 12, the circuit board 61 is provided with a first hall switch 62 at a position corresponding to the first magnetic member 12, and the first hall switch 62 is used for detecting whether the outer cover 11 covers the atomizing assembly 30.

Specifically, after the outer cover 11 is fastened to the atomization cap 32, the atomization cap 32 can be protected, so that the atomization cap 32 is kept clean when not in use. In addition, the second magnetic element 16 provided on the atomization cap 32 can also form magnetic attraction with the first magnetic element 12 on the outer cap 11, so that the outer cap 11 can be further and better fixed on the main body 10. Moreover, the first hall switch 62 can also monitor the pull-out condition of the outer cap 11 by sensing the first magnetic member 12. If the outer cover 11 is not pulled out, the first hall switch 62 detects the presence of the first magnetic member 12, and at this time, the atomizing assembly 30 of the mouth sprayer cannot be opened, so that when the mouth sprayer is placed in the bag, the situation that water mist is sprayed does not occur even if the push button switch 66 is mistakenly pressed. The atomizing assembly 30 can be operated only if the first hall switch 62 detects that the first magnetic member 12 is away, i.e., the outer cap 11 has been pulled out.

As shown in fig. 2, 6 and 9, preferably, a stand 14 is provided in the main body 10, the stand 14 is inserted into the main body 10 from an opening at one end of the main body 10, a receiving chamber 15 is provided on the stand 14, an insertion opening of the receiving chamber 15 is exposed outside the opening at one end of the main body 10, and a liquid chamber 20 containing liquid to be atomized therein can be inserted into the receiving chamber 15 through the insertion opening. The liquid bin 20 is provided with a guide post 21, one end of the guide post 21 is inserted into the liquid bin 20, and the other end of the guide post extends out of the liquid bin 20 by a certain length, so that the liquid to be atomized in the liquid bin 20 is guided out of the liquid bin 20.
