With the development of society and advancements in technology, nebulizers are gradually becoming commonplace in the homes of ordinary people.

[0004] At present, a nebulizer usually includes a main unit and a medicine cup module arranged on the main unit. The medicine cup module includes a medicine cup for holding liquid medicine and an atomization component arranged on the medicine cup. The atomization component is used to make the liquid medicine form a mist. In order to ensure the atomization effect of the liquid medicine, the atomization piece needs to be replaced regularly. The existing method of replacing the atomization piece generally involves replacing the entire medicine cup module or the atomization component, which increases the replacement cost of the atomization piece, and the replacement method is complicated and the stability of the atomization piece is poor. In addition, the existing atomization component is usually exposed to the side of the medicine cup, which affects the cleanliness of the nebulizer. As a result, the user needs to clean the atomization component before using the nebulizer, which affects the user experience. Summary of the Invention

[0010] By adopting the above technical solution, since the cover part covers the recessed part and is flush with the contour surface, the left and right sides of the cover part are flush with the two sides of the atomizer cup. On the one hand, it avoids the situation where the step difference between the atomizer cup and the cover part affects the user's grip, thereby improving the user's grip and further improving the user's usage experience.

On the one hand, the connection points between the cover shell and the atomizer cup are increased to increase the connection stability between the cover shell and the atomizer cup. On the other hand, the difficulty of disassembling and assembling the cover shell is reduced, so as to increase the difficulty of replacing the atomizer disc assembly for the user, thereby further improving the user's usage experience.

[0013] Optionally, the second mating structure includes a connecting arm provided at the front end of the left and right gripping areas, wherein the connecting arm can extend into the recessed portion and be assembled and disassembled with the recessed portion, and the recessed portion has an escape space for the connecting arm to move in a direction away from the contour surface, so that the snap-fitting between the connecting arm and the recessed portion can be released by pressing the connecting arm.

[0014] By adopting the above technical solution, when disassembling the spray hood, the left and right gripping areas of the cover shell are pressed, and then the two connecting arms are respectively moved in the direction away from the contour surface, so that the connecting arms are deformed toward the inside of the recessed portion, thereby releasing the connecting arms from the snap-fit ​​with the recessed portion, and then a pulling force is applied to the spray hood away from the atomizing cup to complete the disassembly of the spray hood. In this process, only the spray hood needs to be pressed and pulled, thereby reducing the difficulty of disassembling the spray hood, improving the efficiency of disassembling the spray hood, and achieving ease of disassembly. The atomizer plate assembly can be replaced; when installing the spray hood, first align the spray hood with the side of the atomizer cup to align the connecting arm with the recessed portion, and then apply a thrust toward the atomizer cup to the spray hood, so that the connecting arm extends into the recessed portion and engages with the recessed portion to complete the installation of the spray hood. In this process, it is only necessary to apply a thrust toward the atomizer cup to the spray hood, thereby greatly reducing the difficulty of installing the spray hood, so as to achieve the effect of facilitating the replacement of the atomizer plate assembly, thereby further improving the user experience.

[0015] Optionally, positioning ribs are provided at the front ends of the left and right gripping areas, and positioning grooves are provided on the left and right sides of the atomizer cup, and the positioning ribs can extend into the positioning grooves to position the cover portion.

[0016] By adopting the above technical solution, after the spray cover is assembled on the atomizer cup, the positioning rib extends into the positioning groove, so that the positioning rib and the positioning groove are plugged into and cooperated to position the spray cover, so as to avoid the situation where the front end of the left and right gripping areas and the outer edge of the atomizer cup have a step difference, thereby improving the appearance quality of the handheld atomizer and further enhancing the user experience.

[0017] Optionally, the medicine liquid containing cavity includes a liquid storage cavity and a liquid conducting cavity located below the liquid storage cavity, the volume of the liquid storage cavity is larger than the volume of the liquid conducting cavity, the medicine liquid outlet is connected to the liquid conducting cavity, and the positioning rib is located above the connecting arm so that the connecting arm and the liquid storage cavity form an avoidance.

[0018] By adopting the above technical solution, since the liquid guide cavity is located below the liquid storage cavity, the positioning rib is located above the connecting arm, and the connecting arm and the recessed portion are arranged relative to each other, the recessed portion is located at the liquid guide cavity, so that the volume of the liquid storage cavity can be made relatively large to ensure the volume of the liquid medicine that can be accommodated in the nebulizer cup, thereby extending the sustainable working time of the handheld nebulizer while keeping the volume of the handheld nebulizer unchanged, thereby further improving the user experience.

[0019] Optionally, the atomizer cup is provided with limiting ribs located outside the liquid medicine outlet, the limiting ribs are distributed along the circumference of the liquid medicine outlet, and the atomizer plate assembly is configured within the limiting ribs.

[0020] By adopting the above technical solution, since the atomizer plate assembly is arranged in the limiting rib, the limiting rib can limit the atomizer plate assembly in the circumferential direction of the medicine liquid outlet, thereby increasing the stability of the atomizer plate assembly to ensure the atomization effect of the handheld atomizer. At the same time, it can also increase the sealing between the atomizer plate assembly and the medicine liquid outlet to avoid leakage of the handheld atomizer, thereby further improving the user experience and reducing the user's usage cost.

[0021] Optionally, the limiting rib is provided with a first fixing portion, and the atomizing plate assembly is provided with a second fixing portion, and the first fixing portion and the second fixing portion can be snap-fitted to fix the atomizing plate assembly.

[0022] By adopting the above technical solution, since the first fixing part and the second fixing part can be snap-fitted, and the first fixing part is arranged on the limiting rib, and the second fixing part is arranged on the atomizer plate assembly, the snap-fitting of the first fixing part and the second fixing part can be used to fix the atomizer plate assembly, so as to further increase the stability of the atomizer plate assembly, and at the same time, it can also achieve the effect of facilitating the assembly of the atomizer plate assembly and the spray hood, so as to further reduce the difficulty of replacing the atomizer plate assembly, thereby further improving the user experience.

[0023] Optionally, the inner side of the housing portion has a contact portion, and the contact portion can contact the atomizer plate assembly and apply pressure to the atomizer plate assembly in a direction toward the atomizer cup.

[0024] By adopting the above technical solution, since the inner side of the spray hood has a contact part, the inner side of the spray hood contacts the atomizer sheet assembly through the contact part, so that the contact part can be used to apply pressure to the atomizer sheet assembly toward the atomizer cup, so that the atomizer sheet assembly can be fixed by squeezing the atomizer sheet assembly by the spray hood, so as to further increase the stability of the atomizer sheet assembly; at the same time, the structure of the spray hood is simplified, so as to facilitate the production of the spray hood and reduce the production cost of the spray hood, and reduce the weight of the spray hood to reduce the weight of the handheld atomizer, so as to further achieve the effect of being convenient for users to carry it, thereby further improving the user experience.

[0025] Optionally, the first matching structure includes a limiting member provided on the atomizer cup, and the limiting member can be matched with the main unit guide and extend into the interior of the main unit.

[0026] By adopting the above technical solution, since the limiting member can cooperate with the main unit guide and extend into the inside of the main unit, when the atomizer cup is assembled on the main unit, the limiting member can guide the atomizer cup to reduce the difficulty of assembling the atomizer cup, thereby achieving the effect of facilitating the assembly of the atomizer cup, thereby improving the assembly efficiency of the atomizer cup and enhancing the user's assembly experience.

[0027] Optionally, the first mating structure also includes a latching arm that can extend into the interior of the host, and the host is provided with a latching block that can move relative to the host, an unlocking button that can move relative to the host and acts on the latching block, and an elastic member acting on the latching block, the latching block having a locking position that is latched with the latching arm and an unlocking position that is separated from the latching arm, when the unlocking button moves along the first direction, the latching block moves toward the unlocking position, the elastic member is deformed and applies an elastic force to the latching block toward the locking position.

[0028] By adopting the above technical solution, when the atomizer cup is disassembled, the unlocking button is pushed in the first direction, and then the unlocking button moves in the first direction, so that the unlocking button drives the clamping block to move toward the unlocking position. At this time, the clamping block applies pressure to the elastic member, and the elastic member undergoes elastic deformation, and finally the clamping block moves to the unlocking position, and the clamping block releases the clamping engagement with the clamping arm. Then, the atomizer cup can be removed from the main unit, and then the unlocking button is released. The elastic member gradually recovers its deformation, so that the clamping block gradually moves to the locked position under the action of the elastic member; When assembling the atomizer cup, first align the atomizer cup with the position where the atomizer cup is installed on the main unit, and then apply pressure to the atomizer cup toward the main unit to make the atomizer cup move toward the direction close to the main unit. The clamping arm extends into the main unit and contacts the clamping block, and continues to apply pressure to the atomizer cup. The clamping arm applies pressure to the clamping block, and the clamping block applies pressure to the elastic member to move the clamping block to the unlocking position. After the atomizer cup is installed in place, the clamping block moves to the locking position under the action of the elastic member and clamps with the clamping arm to complete the installation of the atomizer cup.

[0029] To sum up, when disassembling the atomizer cup, it is only necessary to push the unlocking button along the first direction and apply a force to the atomizer cup in the direction away from the main unit, thereby simplifying the steps of disassembling the atomizer cup, thereby achieving the effect of facilitating the disassembly of the atomizer cup, and thus greatly improving the user experience; when installing the atomizer cup, it is only necessary to apply a force to the atomizer cup in the direction of the main unit, thereby simplifying the installation steps of the atomizer cup, thereby achieving the effect of facilitating the installation of the atomizer cup, and thus also greatly improving the user experience; at the same time, since the clamping block needs to overcome the elastic force of the elastic part when it contacts the clamping arm, the clamping stability of the clamping block with the clamping arm when it is in the locked position is increased, thereby increasing the connection stability of the atomizer cup and the main unit, thereby improving the product quality of the handheld atomizer.

[0030] Optionally, a synchronization block connected to the unlocking button is provided inside the host, the synchronization block is provided with a driving surface, and the snap-connecting block is provided with a mating surface that guides and cooperates with the driving surface, so that when the synchronization block moves in the first direction, the snap-connecting block moves toward the unlocking position under the action of the driving surface and the mating surface.

[0031] By adopting the above technical solution, when the unlocking button moves along the first direction, the unlocking button drives the synchronization block to move, and then the clamping block moves toward the unlocking position under the cooperation of the mating surface and the driving surface, so that when the unlocking button moves along the first direction, the clamping block moves toward the unlocking position; and by providing the synchronization block, on the one hand, the structure of the unlocking button can be simplified, so as to achieve the effect of facilitating the production of the unlocking button and reducing the production cost of the unlocking button; on the other hand, it can achieve the effect of facilitating the assembly of the unlocking button, so as to improve the production efficiency of the handheld atomizer.

On the one hand, the atomization effect of the handheld atomizer is ensured, and on the other hand, the waste of liquid medicine is avoided. At the same time, the cleanliness of the handheld atomizer is ensured, thereby further improving the user experience.

[0036] Optionally, the sealing portion extends into the liquid medicine outlet and has an interference fit with the wall of the liquid medicine outlet.

[0037] By adopting the above technical solution, since the sealing part extends into the liquid medicine outlet and has an interference fit with the wall of the liquid medicine outlet, on the one hand, the sealing between the atomizer assembly and the atomizer cup is further increased, so as to further improve the atomization effect of the liquid medicine, and on the other hand, the connection stability between the atomizer assembly and the atomizer cup is further increased, so as to further increase the stability of the atomizer assembly.

[0039] By adopting the above technical solution, since the elastic conductive column can extend into the accommodating cavity through the through hole to elastically contact the conductive part, elastic contact between the elastic conductive column and the conductive part is achieved, so as to avoid deformation of the conductive part and poor contact between the elastic conductive column and the conductive part, thereby increasing the electrical connection stability between the elastic conductive column and the conductive part, and then ensuring the normal operation of the handheld atomizer, so as to further improve the product quality of the handheld atomizer.

[0040] Optionally, the rear sealing ring has a supporting portion that contacts the conductive portion;

[0041] Alternatively, the rear sealing ring is arranged to avoid the conductive part, and the rear shell is provided with a supporting protrusion that contacts the conductive part.

[0042] By adopting the above technical solution, since the rear sealing ring has a support part that contacts the conductive part, the support part can elastically support the conductive part, thereby increasing the ability of the conductive part to recover deformation, thereby ensuring the contact stability between the elastic conductive column and the conductive part, and thereby increasing the electrical connection stability between the elastic conductive column and the conductive part.

[0043] Since the rear shell is provided with a supporting protrusion that contacts the conductive part, the supporting protrusion can support the conductive part to avoid the situation where the elastic conductive column cannot contact the conductive part due to deformation of the conductive part, thereby ensuring the contact stability between the elastic conductive column and the conductive part, and further increasing the electrical connection stability between the elastic conductive column and the conductive part.

[0044] Optionally, the front shell is provided with a snap-fitting portion, and the rear shell is provided with a matching portion capable of snap-fitting with the snap-fitting portion.

[0045] By adopting the above technical solution, when replacing the atomizer sheet, it is only necessary to release the snap fit between the snap fit portion on the front shell and the mating portion on the rear shell, thereby simplifying the operation steps for replacing the atomizer sheet, thereby achieving the effect of facilitating the replacement of the atomizer sheet, while also improving the replacement efficiency of the atomizer sheet, thereby further enhancing the user experience.

[0046] Optionally, the nebulizer cup includes a cup body and a cover body covering the top of the cup body for sealing the liquid medicine storage chamber, the cover body and the main unit form a storage space for accommodating the cover part on the side of the cup body, and the height of the storage space close to the cup body is smaller than the height of the storage space away from the cup body.

[0047] By adopting the above technical solution, since the height of the accommodating space close to the cup body is smaller than the height of the accommodating space away from the cup body, the opening of the accommodating space is increased, so that the spray hood can be assembled in the accommodating space through the opening of the accommodating space, thereby further improving the user's assembly efficiency of the spray hood and further improving the user's usage experience.

[0048] Optionally, the top wall of the main unit has an inclined section and straight sections located on both sides of the inclined section, and the inclined section is arranged to be inclined upward in a direction close to the cup body.

[0049] By adopting the above technical solution, since the inclined section is tilted upward in the direction close to the cup body, the height of the accommodating space close to the cup body is smaller than the height of the accommodating space away from the cup body, and the straight section can also support the cup body and the spray hood to increase the stability of the cup body and the spray hood.

[0050] Optionally, the host includes a casing, a circuit board arranged inside the casing, and a switch button located on the side of the casing, the circuit board has a trigger part corresponding to the switch button, the switch button is clamped to the casing and can move relative to the casing to trigger the trigger part, and an elastic seal is arranged between the switch button and the casing.

[0051] By adopting the above technical solution, when the handheld atomizer is started, the switch button is pressed, and the switch button applies pressure to the elastic seal, which then causes the elastic seal to deform, so that the switch button contacts the trigger part and applies pressure to the trigger part, thereby starting the handheld atomizer. After the switch button is released, the elastic seal gradually recovers its deformation and applies an elastic force toward the outside of the casing to the switch button, so that the switch button moves toward the outside of the casing and separates from the trigger part. Through the provision of the elastic seal, on the one hand, a seal is achieved between the switch button and the casing to improve the waterproof performance of the handheld atomizer. On the other hand, the switch button can be kept separated from the trigger part without being affected by other external factors, so as to ensure the stability of the handheld atomizer. At the same time, the force required to trigger the handheld atomizer is increased, so as to greatly reduce the probability of false triggering of the handheld atomizer, thereby further improving the user experience.

[0052] Optionally, the circuit board is provided with an indicator light, and the housing is provided with a thin-walled area corresponding to the indicator light, so that light emitted by the indicator light can penetrate the housing;

[0053] Alternatively, the housing is provided with a light display hole corresponding to the indicator light, and the housing is provided with a light-transmitting waterproof sticker covering the light display hole.

[0054] By adopting the above technical solution, since the casing is provided with a thin-walled area corresponding to the indicator light, the light emitted by the indicator light can penetrate the casing for the user's reference. At the same time, the indicator light can be hidden inside the casing to avoid the need to provide a hole structure in the casing for the indicator light to pass through, thereby greatly improving the waterproof performance of the handheld atomizer, thereby further enhancing the user experience.

[0055] Since the casing is provided with a translucent waterproof sticker covering the light display hole, the light emitted by the indicator light passes through the light display hole and the translucent waterproof sticker and out of the casing for user reference. The translucent waterproof sticker can also improve the waterproof performance of the handheld atomizer, thereby further enhancing the user experience.

[0056] Optionally, the inner wall of the housing is provided with a light-shielding rib opposite to the indicator light, and the light-shielding rib surrounds the outer circumference of the indicator light.

[0057] By adopting the above technical solution, since the shading rib surrounds the outer periphery of the indicator light, the shading rib can block the light emitted by the indicator light to prevent the light emitted by the indicator light from diverging outward, thereby making the light emitted by the indicator light more concentrated, thereby improving the lighting effect of the indicator light and further improving the prompt effect for the user.

The left and right gripping areas are detachably matched with the left and right sides of the atomizer cup through the second matching structure. Since the cover shell portion is U-shaped, the cover shell portion can be completely covered on the outside of the atomizer sheet assembly to further improve the dustproof and protective effect of the atomizer sheet assembly, so as to further reduce the replacement frequency of the atomizer sheet assembly, thereby further reducing the user's usage cost; and the second matching structure is arranged on the left and right gripping areas. The left and right gripping areas are detachably matched with the left and right sides of the atomizer cup through the second matching structure.

[0079] Reference Figures 1 to 9 , discloses a handheld nebulizer, which includes a main unit 1, an atomizer cup, an atomizer sheet assembly 3 and a spray cover, wherein the bottom of the atomizer cup has a first matching structure, and the atomizer cup can be disassembled and matched with the top of the main unit 1 through the first matching structure, the atomizer cup has a liquid medicine accommodating chamber and a liquid medicine inlet and a liquid medicine outlet 21 connected to the liquid medicine accommodating chamber, the liquid medicine outlet 21 is configured to be able to be closed by the atomizer sheet assembly 3, the spray cover has a mist outlet nozzle 41 and a cover shell 4, and the cover shell 4 is provided with a second matching structure, and the spray cover can be disassembled and matched with the atomizer cup via the second matching structure.

[0080] Since the atomizer cup can be assembled and disassembled with the top of the main unit 1 through the first matching structure, the atomizer cup can be separated from the main unit 1 to facilitate cleaning and disinfection of the atomizer cup, thereby improving the cleanliness of the atomizer cup and improving the user experience; in addition, compared with the solution in which the atomizer cup and the main unit 1 are integrated, it avoids the situation where cleaning water or disinfectant water seeps into the main unit 1 when the atomizer cup is cleaned or disinfected, thereby achieving the effect of extending the service life of the handheld atomizer and ensuring safety in use.

[0081] Since the medicine liquid outlet 21 is configured to be closed by the atomizer disc assembly 3, the atomizer disc assembly 3 can be replaced separately, so as to reduce the user's usage cost and improve the user's usage experience; and the spray cover can be disassembled and assembled with the atomizer cup via the second matching structure. On the one hand, when the atomizer disc assembly 3 is replaced, the spray cover can be removed to reduce the user's operation steps for replacing the atomizer disc 33, so as to improve the user's efficiency in replacing the atomizer disc assembly 3. On the other hand, the spray cover can also prevent dust and protect the atomizer disc assembly 3, so as to increase the cleanliness of the atomizer disc assembly 3 and reduce the replacement frequency of the atomizer disc assembly 3, so as to further reduce the user's usage cost and improve the user's usage experience. At the same time, the spray cover can also assist in fixing the atomizer disc assembly 3 to increase the stability of the atomizer disc assembly 3, thereby improving the atomization effect of the handheld nebulizer.

[0082] In a preferred embodiment, referring to Figure 7 The left and right sides of the atomizer cup respectively have a recessed portion 261 and a contour surface, and the cover portion 4 covers the recessed portion 261 and is flush with the contour surface, so that the left and right sides of the cover portion 4 are flush with the sides of the atomizer cup. On the one hand, it avoids the situation where the step difference between the atomizer cup and the cover portion 4 affects the user's grip, thereby improving the user's grip and further improving the user's usage experience. On the other hand, it reduces the volume of the handheld atomizer, making it easier for the user to carry the handheld atomizer, thereby further improving the user's usage experience.

[0083] Furthermore, the cover portion 4 is U-shaped and has left and right gripping areas, and the second matching structures are provided in the left and right gripping areas. The left and right gripping areas are matched with the left and right sides of the atomizer cup through the second matching structures.

[0084] Since the cover shell portion 4 is U-shaped, the cover shell portion 4 can be completely covered on the outside of the atomizer disc assembly 3, so as to further improve the dustproof and protective effect of the atomizer disc assembly 3, so as to further reduce the replacement frequency of the atomizer disc assembly 3, thereby further reducing the user's usage cost; and the second matching structure is provided in the left and right gripping areas, and the left and right gripping areas are disassembled and matched with the left and right sides of the atomizer cup through the second matching structure. On the one hand, the connection points between the cover shell portion 4 and the atomizer cup are increased to increase the connection stability between the cover shell portion 4 and the atomizer cup. On the other hand, the difficulty of disassembling and assembling the cover shell portion 4 is reduced, so as to increase the difficulty of replacing the atomizer disc assembly 3 for the user, thereby further improving the user's usage experience.

[0085] The present application does not make any specific limitation on the structure of the second matching structure. Preferably, refer to Figure 3 、 Figure 7 and Figure 8 The second matching structure includes a connecting arm 43 provided at the front end of the left and right gripping areas. The connecting arm 43 can extend into the recessed portion 261 and be assembled and disassembled with the recessed portion 261, and the recessed portion 261 has an escape space for the connecting arm 43 to move in a direction away from the contour surface, so that the engagement between the connecting arm 43 and the recessed portion 261 can be released by pressing the connecting arm 43.

[0086] It can be understood that the recessed portion 261 is located on the inner side of the contour surface. The recessed portion 261 is a hole structure with an opening, and the opening of the hole structure faces the side where the spray hood is located. The connecting arm 43 is snap-fitted with the inner wall of the recessed portion 261 close to the contour surface.

[0087] When disassembling the spray hood, press the left and right gripping areas of the cover shell 4, and then make the two connecting arms 43 move in the direction away from the contour surface, so that the connecting arms 43 are deformed toward the inner side of the recessed portion 261, thereby releasing the connecting arms 43 from the snap fit with the recessed portion 261, and then apply a pulling force away from the atomizer cup to complete the disassembly of the spray hood. In this process, you only need to press and pull the spray hood, thereby reducing the difficulty of disassembling the spray hood, improving the disassembly efficiency of the spray hood, and achieving the effect of facilitating the replacement of the atomizer plate assembly 3.

[0088] When installing the spray hood, first align the spray hood with the side of the atomizer cup so that the connecting arm 43 is aligned with the recessed portion 261, and then apply a thrust toward the atomizer cup to the spray hood, so that the connecting arm 43 extends into the recessed portion 261 and engages with the recessed portion 261 to complete the installation of the spray hood. In this process, it is only necessary to apply a thrust toward the atomizer cup to the spray hood, thereby greatly reducing the difficulty of installing the spray hood, so as to facilitate the replacement of the atomizer sheet assembly 3, thereby further improving the user experience.

[0089] In other implementation examples, the second mating structure may also include a magnetic block and an iron sheet that can magnetically engage with the magnetic block. The magnetic block and the iron sheet are respectively arranged at the front ends of the recessed portion 261 and the left and right gripping areas to achieve the connection between the spray hood and the atomizer cup by magnetic engagement.

[0090] Further, refer to Figure 3 、 Figure 7 and Figure 8 Positioning ribs 44 are provided at the front ends of the left and right gripping areas, and positioning grooves 27 are provided on the left and right sides of the atomizer cup. The positioning ribs 44 can extend into the positioning grooves 27 to position the cover part 4.

[0091] After the spray cover is assembled on the atomizer cup, the positioning rib 44 extends into the positioning groove 27 so that the positioning rib 44 and the positioning groove 27 are plugged into each other to position the spray cover, thereby avoiding the situation where the front ends of the left and right gripping areas and the outer edge of the atomizer cup have a step difference, thereby improving the appearance quality of the handheld atomizer and further enhancing the user experience.

[0092] Further, refer to Figure 4 The liquid medicine storage chamber includes a liquid storage chamber 28 and a liquid guide chamber 29 located below the liquid storage chamber 28. The volume of the liquid storage chamber 28 is larger than the volume of the liquid guide chamber 29. The liquid medicine outlet 21 is connected to the liquid guide chamber 29. The positioning rib 44 is located above the connecting arm 43 so that the connecting arm 43 and the liquid storage chamber 28 form a avoidance.

[0093] Since the liquid guide cavity 29 is located below the liquid storage cavity 28, the positioning rib 44 is located above the connecting arm 43, and the connecting arm 43 is arranged opposite to the recessed portion 261, the recessed portion 261 is located at the liquid guide cavity 29, so that the volume of the liquid storage cavity 28 can be made relatively large to ensure the volume of the liquid medicine that can be accommodated in the nebulizer cup, thereby extending the sustainable working time of the handheld nebulizer without changing the volume of the handheld nebulizer, thereby further improving the user experience.

[0094] The present application does not specifically limit the fixing method of the atomizer assembly 3, and it can adopt any one or more combinations of the following embodiments:

[0095] Implementation method 1: In this implementation method, refer to Figure 3 The atomizer cup is provided with a limiting rib 22 located on the outside of the liquid medicine outlet 21. The limiting rib 22 is distributed along the circumference of the liquid medicine outlet 21. The atomizer plate assembly 3 is arranged in the limiting rib 22, so that the limiting rib 22 can limit the atomizer plate assembly 3 in the circumference of the liquid medicine outlet 21, thereby increasing the stability of the atomizer plate assembly 3 to ensure the atomization effect of the handheld atomizer. At the same time, it can also increase the sealing between the atomizer plate assembly 3 and the liquid medicine outlet 21 to avoid leakage of the handheld atomizer, thereby further improving the user experience and reducing the user's usage cost.

[0096] The present application does not make any specific limitation on the structure of the limiting rib 22. Preferably, refer to Figure 3 The limiting rib 22 is a rib structure whose shape is adapted to the outer periphery of the atomizer disc assembly 3. There are two limiting ribs 22, one located on the upper and lower sides of the liquid medicine outlet 21, to limit the atomizer disc assembly 3 in the vertical direction. While increasing the stability of the atomizer disc assembly 3, it can also form a clearance with the left and right sides of the atomizer disc assembly 3, so as to form space on the left and right sides of the atomizer disc assembly 3 to accommodate the user's hands, thereby achieving the effect of facilitating the user's disassembly and assembly of the atomizer disc assembly 3, thereby further improving the user's experience. In other embodiments, the limiting rib 22 can also be an annular structure extending circumferentially along the liquid medicine outlet 21 to increase the limiting effect on the atomizer disc assembly 3.

[0097] Further, refer to Figure 3 The limiting rib 22 is provided with a first fixing portion 221 , and the atomizing plate assembly 3 is provided with a second fixing portion 351 . The first fixing portion 221 and the second fixing portion 351 can be snap-fitted to fix the atomizing plate assembly 3 .

[0098] Since the first fixing portion 221 and the second fixing portion 351 can be snap-fitted, and the first fixing portion 221 is provided on the limiting rib 22, and the second fixing portion 351 is provided on the atomizer plate assembly 3, the snap-fitting of the first fixing portion 221 and the second fixing portion 351 can be utilized to fix the atomizer plate assembly 3, so as to further increase the stability of the atomizer plate assembly 3, and at the same time, it can also achieve the effect of facilitating the assembly of the atomizer plate assembly 3 and the spray hood, so as to further reduce the difficulty of replacing the atomizer plate assembly 3, thereby further improving the user experience.

[0099] The present application does not specifically limit the structures of the first fixing portion 221 and the second fixing portion 351. Preferably, refer to Figure 3 The first fixing portion 221 is a hole structure provided in the limiting rib 22, and the second fixing portion 351 is a block structure provided in the atomizing disc assembly 3 and arranged corresponding to the hole structure. The block structure and the hole structure cooperate to achieve a snap-fit ​​connection between the atomizing disc assembly 3 and the limiting rib 22. In other embodiments, the first fixing portion 221 and the second fixing portion 351 can also be other structures that can be snap-fitted together, such as a ball spring structure and a groove.

[0100] Implementation method 2: In this implementation method, refer to Figure 8 The inner side of the housing portion 4 has a contact portion 42 , which can contact the atomizing sheet assembly 3 and apply pressure to the atomizing sheet assembly 3 toward the atomizing cup.

[0101] Since the inner side of the spray hood has a contact portion 42, the inner side of the spray hood contacts the atomizer sheet assembly 3 through the contact portion 42, so that the contact portion 42 can be used to apply pressure to the atomizer sheet assembly 3 toward the atomizer cup, so that the spray hood can be used to squeeze the atomizer sheet assembly 3 to achieve the fixation of the atomizer sheet assembly 3, thereby further increasing the stability of the atomizer sheet assembly 3.

[0102] The present application does not specifically limit the structure of the contact portion 42. Preferably, refer to Figure 8 The contact portion 42 is a convex rib provided on the inner side of the cover portion 4 to simplify the structure of the spray hood, thereby facilitating the production of the spray hood and reducing the production cost of the spray hood, and reducing the weight of the spray hood to reduce the weight of the handheld atomizer, so as to further facilitate the user to carry it, thereby further improving the user experience.

[0103] Preferably, at least two convex ribs are provided, and the two convex ribs respectively abut against the upper and lower positions of the atomizer plate assembly 3, or the two convex ribs respectively abut against the left and right positions of the atomizer plate assembly 3, or one convex rib is provided and extends along the circumference of the atomizer plate assembly 3.

[0104] In other implementation examples, the contact portion 42 may also be a block structure or other structure that can interfere with the atomizer assembly 3 .

[0105] In a preferred embodiment, referring to Figure 4 The first matching structure includes a limiting member 23 provided on the atomizer cup. The limiting member 23 can be guided and matched with the main unit 1 and extend into the interior of the main unit 1.

[0106] Since the limiting member 23 can cooperate with the main unit 1 and extend into the interior of the main unit 1, when the atomizer cup is assembled on the main unit 1, the limiting member 23 can guide the atomizer cup to reduce the difficulty of assembling the atomizer cup, thereby achieving the effect of facilitating the assembly of the atomizer cup, thereby improving the assembly efficiency of the atomizer cup and enhancing the user's assembly experience.

[0107] The present application does not specifically limit the structure of the stopper 23. Preferably, the stopper 23 is a rib structure provided at the bottom of the atomizer cup, and a hole structure adapted to the rib structure is provided at the top of the main unit 1. When the atomizer cup is assembled, the rib structure and the hole structure provided at the top of the main unit 1 are plugged and matched, thereby guiding the atomizer cup and positioning the atomizer cup, thereby increasing the stability of the connection between the atomizer cup and the main unit 1. In other embodiments, the stopper 23 may also be a rod-shaped structure.

[0108] In a preferred embodiment, referring to Figure 4 、 Figure 5 and Figure 6 The first matching structure also includes a clamping arm 24 that can extend into the interior of the host 1. The host 1 is provided with a clamping block 111 that can move relative to the host 1, an unlocking button 112 that can move relative to the host 1 and acts on the clamping block 111, and an elastic member 113 that acts on the clamping block 111. The clamping block 111 has a locking position in which it is clamped with the clamping arm 24 and an unlocking position separated from the clamping arm 24. When the unlocking button 112 moves along the first direction, the clamping block 111 moves toward the unlocking position, the elastic member 113 is deformed and applies an elastic force to the clamping block 111 to move toward the locking position.

[0109] When the atomizer cup is disassembled, the unlocking button 112 is pushed in the first direction, and then the unlocking button 112 moves in the first direction, so that the unlocking button 112 drives the clamping block 111 to move toward the unlocking position. At this time, the clamping block 111 applies pressure to the elastic member 113, and the elastic member 113 is elastically deformed, and finally the clamping block 111 moves to the unlocking position. The clamping block 111 releases the clamping engagement with the clamping arm 24, and then the atomizer cup can be removed from the main unit 1. Then, the unlocking button 112 is released, and the elastic member 113 gradually recovers its deformation, so that the clamping block 111 gradually moves to the locked position under the action of the elastic member 113; When assembling the atomizer cup, first align the atomizer cup with the position where the atomizer cup is installed on the host 1, and then apply pressure to the atomizer cup toward the host 1 to make the atomizer cup move toward the direction close to the host 1. The clamping arm 24 extends into the host 1 and contacts the clamping block 111. Continue to apply pressure to the atomizer cup. The clamping arm 24 applies pressure to the clamping block 111, and the clamping block 111 applies pressure to the elastic member 113 to move the clamping block 111 to the unlocked position. After the atomizer cup is installed in place, the clamping block 111 moves to the locked position under the action of the elastic member 113 and is clamped and matched with the clamping arm 24 to complete the installation of the atomizer cup.

[0110] In summary, when disassembling the atomizer cup, it is only necessary to push the unlocking button 112 along the first direction and apply a force to the atomizer cup in a direction away from the main unit 1, thereby simplifying the steps of disassembling the atomizer cup, thereby achieving the effect of facilitating the disassembly of the atomizer cup, and thus greatly improving the user experience; when installing the atomizer cup, it is only necessary to apply a force to the atomizer cup in a direction toward the main unit 1, thereby simplifying the installation steps of the atomizer cup, thereby achieving the effect of facilitating the installation of the atomizer cup, and thus also greatly improving the user experience; at the same time, since the clamping block 111 needs to overcome the elastic force of the elastic member 113 when it contacts the clamping arm 24, the clamping stability of the clamping block 111 and the clamping arm 24 when in the locked position is increased, thereby increasing the connection stability between the atomizer cup and the main unit 1, and improving the product quality of the handheld atomizer.

[0111] The present application does not specifically limit the first direction. Preferably, the first direction is an upward direction along the outer contour of the main unit 1 to facilitate the release of the clamping arm 24, thereby improving the efficiency of removing the atomizer cup. In other embodiments, the first direction can also be other directions, as long as the clamping block 111 moves in the unlocking direction when the unlock button 112 moves in the first direction.

[0112] The present application does not make any specific limitation on the structure of the elastic member 113. Preferably, refer to Figure 5The elastic member 113 is a spring to ensure that the elastic member 113 can exert an elastic force on the clamping block 111, thereby ensuring the clamping stability of the clamping block 111 and the clamping arm 24, and further ensuring the stability of the connection between the atomizer cup and the main unit 1. In other embodiments, the elastic member 113 can also be an elastic column, an elastic sheet, or other structures that can exert an elastic force on the clamping block 111.

[0113] Further, refer to Figure 5 A synchronization block 114 connected to the unlocking button 112 is provided inside the host 1. The synchronization block 114 is provided with a driving surface, and the clamping block 111 is provided with a mating surface that guides the driving surface, so that when the synchronization block 114 moves in the first direction, the clamping block 111 moves toward the unlocking position under the action of the driving surface and the mating surface.

[0114] When the unlock button 112 moves along the first direction, the unlock button 112 drives the synchronization block 114 to move, and then the locking block 111 moves toward the unlock position under the cooperation of the mating surface and the driving surface, so that when the unlock button 112 moves along the first direction, the locking block 111 moves toward the unlock position.

[0115] By setting the synchronization block 114, on the one hand, the structure of the unlock button 112 can be simplified, so as to facilitate the production of the unlock button 112 and reduce the production cost of the unlock button 112. On the other hand, it can facilitate the assembly of the unlock button 112 to improve the production efficiency of the handheld atomizer.

[0116] Better, refer to Figure 5 and Figure 6 The host 1 is provided with a mounting frame 11, a clamping block 111, a synchronization block 114 and an elastic member 113 are arranged inside the mounting frame 11, and sliders slidably connected to the mounting frame 11 are provided on opposite sides of the clamping block 111 and the synchronization block 114 to increase the stability of the clamping block 111 and the synchronization block 114 when they slide. The mounting frame 11 is provided with a limiting column for limiting the elastic member 113. One end of the elastic member 113 is sleeved on the limiting column, and the other end of the elastic member 113 is sleeved on the end of the clamping block 111 to increase the stability of the elastic member 113. In addition, the provision of the mounting frame 11 simplifies the internal structure of the housing 12 of the host 1, thereby reducing the difficulty of producing the housing 12, improving the production efficiency of the housing 12 and reducing the production cost of the housing 12.

[0117] In a preferred embodiment, referring to Figure 3 、 Figure 4 and Figure 9The atomizer assembly 3 includes a shell and an atomizer 33. The shell includes a front shell 31 and a rear shell 32. The front shell 31 and the rear shell 32 are detachably connected and together form a receiving cavity. The atomizer 33 is configured in the receiving cavity.

[0118] It can be understood that both the front shell 31 and the rear shell 32 are provided with a hole structure corresponding to the liquid medicine outlet 21, so that the liquid medicine can flow to the position of the atomizing plate 33 through the hole structure on the front shell 31, and after the liquid medicine becomes mist under the atomization action of the atomizing plate 33, it can enter the spray hood through the hole structure on the rear shell 32.

[0119] Since the atomizing sheet 33 is arranged in the accommodating cavity, the stability of the atomizing sheet 33 can be increased, thereby increasing the stability of the handheld atomizer during operation; and since the front shell 31 and the rear shell 32 are detachably connected, the atomizing sheet 33 can be replaced separately, thereby further reducing the user's usage cost.

[0120] Further, refer to Figure 9 The accommodating cavity is provided with a front sealing ring 34 and a rear sealing ring 35 located on opposite sides of the atomizing sheet 33. The front sealing ring 34 has a sealing portion 341 extending out of the front shell 31 and used to contact the atomizing cup, thereby increasing the sealing between the atomizing sheet 33 and the shell to ensure the atomization effect of the handheld atomizer; and the front sealing ring 34 has a sealing portion 341 extending out of the front shell 31 and used to contact the atomizing cup, thereby increasing the sealing between the atomizing sheet assembly 3 and the atomizing cup to prevent the liquid flowing out through the liquid medicine outlet 21 from overflowing through the gap between the shell and the atomizing cup. On the one hand, the atomization effect of the handheld atomizer is ensured, and on the other hand, the waste of liquid medicine is avoided. At the same time, the cleanliness of the handheld atomizer is ensured, thereby further improving the user experience.

[0121] It can be understood that the front sealing ring 34 and the rear sealing ring 35 are also provided with a hole structure corresponding to the liquid medicine outlet 21 to ensure that the liquid medicine can contact the atomizing plate 33 and the atomized liquid medicine can enter the spray hood; in addition, it can also ensure that the sealing part 341 can extend out of the front shell 31.

[0122] Furthermore, the sealing portion 341 extends into the liquid medicine outlet 21 and has an interference fit with the mouth wall of the liquid medicine outlet 21. On the one hand, it further increases the sealing between the atomizer plate assembly 3 and the atomizer cup to further improve the atomization effect of the liquid medicine. On the other hand, it further increases the connection stability between the atomizer plate assembly 3 and the atomizer cup to further increase the stability of the atomizer plate assembly 3.

[0123] Preferably, the sealing portion 341 is an annular structure that is continuously extended along the liquid medicine outlet 21 to ensure the connection stability between the sealing portion 341 and the wall of the liquid medicine outlet 21, thereby improving the sealing between the atomizer assembly 3 and the atomizer cup.

[0124] In a preferred embodiment, the atomizer plate 33 has a conductive portion 331 , the shell is provided with a through hole 311 corresponding to the conductive portion 331 , and the atomizer cup is provided with an elastic conductive column 25 , which can extend into the accommodating cavity through the through hole 311 to elastically resist the conductive portion 331 .

[0125] Since the elastic conductive column 25 can extend into the accommodating cavity through the through hole 311 to elastically contact the conductive part 331, elastic contact between the elastic conductive column 25 and the conductive part 331 is achieved, so as to avoid deformation of the conductive part 331 and poor contact between the elastic conductive column 25 and the conductive part 331, thereby increasing the electrical connection stability between the elastic conductive column 25 and the conductive part 331, and thus ensuring the normal operation of the handheld atomizer, thereby further improving the product quality of the handheld atomizer.

[0126] It is understandable that the front housing 31 is disposed opposite to the atomizer cup, and the through hole 311 is provided in the front housing 31 to ensure that the elastic conductive column 25 can extend into the accommodating cavity and elastically contact the conductive portion 331 .

[0127] Preferably, the front sealing ring 34 has an extension portion opposite to the conductive portion 331, and the extension portion contacts the conductive portion 331, so that the extension portion can support the conductive portion 331 to reduce the deformation of the conductive portion 331, further ensuring the electrical connection stability between the elastic conductive column 25 and the conductive portion 331, and the through hole 311 extends to the extension portion, so that the elastic conductive column 25 elastically contacts the conductive portion 331 after passing through the extension portion, to ensure that the elastic conductive column 25 can contact the conductive portion 331.

[0128] The present application does not specifically limit the structure of the rear sealing ring 35, which may adopt any one of the following implementation examples:

[0129] Implementation Example 1. In this implementation example, the rear sealing ring 35 has a supporting portion that contacts the conductive portion 331, so that the supporting portion can elastically support the conductive portion 331, thereby increasing the ability of the conductive portion 331 to restore deformation, thereby ensuring the contact stability between the elastic conductive column 25 and the conductive portion 331, and thereby increasing the electrical connection stability between the elastic conductive column 25 and the conductive portion 331.

[0130] Implementation Example 2: In this implementation example, refer to Figure 9The rear sealing ring 35 and the conductive part 331 are arranged to avoid each other, and the rear shell 32 is provided with a support protrusion 321 that contacts the conductive part 331, so that the support protrusion 321 can support the conductive part 331 to avoid the elastic conductive column 25 from being unable to contact it due to deformation of the conductive part 331, thereby ensuring the contact stability of the elastic conductive column 25 and the conductive part 331, and further increasing the electrical connection stability of the elastic conductive column 25 and the conductive part 331.

[0131] The present application does not make any specific limitation on the detachable connection method between the front housing 31 and the rear housing 32. Preferably, refer to Figure 9 The front shell 31 is provided with a clamping portion 312, and the rear shell 32 is provided with a matching portion 322 that can be clamped and matched with the clamping portion 312. When replacing the atomizer sheet 33, it is only necessary to release the clamping cooperation between the clamping portion 312 on the front shell 31 and the matching portion 322 on the rear shell 32, thereby simplifying the operation steps when replacing the atomizer sheet 33, thereby achieving the effect of facilitating the replacement of the atomizer sheet 33, and at the same time improving the replacement efficiency of the atomizer sheet 33, thereby further enhancing the user experience.

[0132] The present application does not specifically limit the structures of the snap-fitting portion 312 and the mating portion 322. Preferably, the snap-fitting portion 312 is a block-shaped structure provided on the side of the front housing 31, and the rear housing 32 is provided with an edge located along the outer periphery of the front housing 31. The mating portion 322 is a hole structure provided along the edge and corresponding to the block-shaped structure. The snap-fitting of the block structure provided on the side of the front housing 31 with the hole structure provided along the edge achieves a detachable connection between the front housing 31 and the rear housing 32. In other embodiments, the snap-fitting portion 312 and the mating portion 322 may also be other structures capable of achieving snap-fitting, such as block-shaped structures that are mutually offset and engage at the sides.

[0133] In other embodiments, the front housing 31 may also be detachably connected to the rear housing 32 by screws.

[0134] In a preferred embodiment, the atomizer cup includes a cup body 2 and a cover body 5 covering the top of the cup body 2 for sealing the liquid storage chamber. The cover body 5 and the main body 1 form a storage space for the cover shell part 4 on the side of the cup body 2. The height of the storage space close to the cup body 2 is less than the height of the storage space away from the cup body 2, thereby increasing the opening of the storage space, so that the spray cover can be assembled in the storage space through the opening of the storage space, thereby further improving the user's assembly efficiency of the spray cover, and further improving the user's usage experience.

[0135] The present application does not make any specific limitation on the formation method of the height of the accommodating space away from the cup body 2 being smaller than the height of the accommodating space away from the cup body 2. Preferably, the top wall of the main unit 1 has an inclined section and straight sections on both sides of the inclined section, and the inclined section is inclined upward in the direction close to the cup body 2, thereby achieving the height of the accommodating space close to the cup body 2 being smaller than the height of the accommodating space away from the cup body 2, and the straight section can also support the cup body 2 and the spray hood to increase the stability of the cup body 2 and the spray hood.

[0136] Preferably, the top projection of the cup body 2 is located within one of the straight sections, so that the bottom of the cup body 2 is relatively flat, thereby reducing the production difficulty of the cup body 2, thereby reducing the production cost of the cup body 2, and further reducing the production cost of the handheld atomizer.

[0137] In other embodiments, the entire top wall of the main unit 1 may be inclined to achieve a height of the accommodating space close to the cup body 2 that is smaller than a height of the accommodating space away from the cup body 2 .

[0138] In a preferred embodiment, referring to Figure 4 The host 1 includes a housing 12, a circuit board 13 arranged inside the housing 12, and a switch button 121 located on the side of the housing 12. The circuit board 13 has a trigger portion 131 arranged corresponding to the switch button 121. The switch button 121 is snapped onto the housing 12 and can move relative to the housing 12 to trigger the trigger portion 131. An elastic seal 122 is provided between the switch button 121 and the housing 12.

[0139] Specifically, when starting the handheld atomizer, the switch button 121 is pressed, and the switch button 121 applies pressure to the elastic seal 122, which then causes the elastic seal 122 to deform, so that the switch button 121 contacts the trigger portion 131 and applies pressure to the trigger portion 131, thereby starting the handheld atomizer. After releasing the switch button 121, the elastic seal 122 gradually recovers its deformation and applies an elastic force toward the outside of the housing 12 to the switch button 121, so that the switch button 121 moves toward the outside of the housing 12 and separates from the trigger portion 131.

[0140] By setting the elastic sealing member 122, on the one hand, a seal is achieved between the switch button 121 and the housing 12 to improve the waterproof performance of the handheld atomizer. On the other hand, the switch button 121 can be kept separated from the trigger portion 131 without being affected by other external factors to ensure the stability of the handheld atomizer. At the same time, the force required to trigger the handheld atomizer is increased, thereby greatly reducing the probability of false triggering of the handheld atomizer and further improving the user experience.

[0141] Preferably, the switch button 121 has a trigger rod extending into the interior of the housing 12 and used to trigger the trigger part 131, and an elastic arm that engages with the inner wall of the housing 12, so that the trigger part 131 is triggered when the switch button 121 is pressed and the switch button 121 is connected to the housing 12.

[0142] The structure of the elastic seal 122 is not specifically limited in this application. Preferably, the elastic seal 122 is an elastic sleeve made of rubber or silicone material to achieve sealing between the switch button 121 and the housing 12 while also resetting the switch button 121. In other embodiments, the elastic seal 122 may further include a sealing membrane and an elastic portion, one end of the sealing membrane being connected to the switch button 121, and one end of the sealing membrane being connected to the housing 12, and the elastic portion being used to apply a force to the switch button 121 toward the outside of the housing 12.

[0143] In order to help users understand the working status of the handheld atomizer, refer to Figure 4 The circuit board 13 is provided with an indicator light 132, which can be turned on or off according to the start or shut down of the handheld atomizer.

[0144] In order to increase the waterproof performance of the handheld atomizer and increase the prompt effect of the indicator light 132 on the user, any one of the following implementation examples may be adopted:

[0145] Implementation Example 1: In this implementation example, refer to Figure 4 The casing 12 is provided with a thin-walled area 123 corresponding to the indicator light 132, so that the light emitted by the indicator light 132 can penetrate the casing 12, and then when the indicator light 132 is lit, it penetrates the thin-walled area 123 to clearly indicate the working status of the handheld atomizer to the user. At the same time, the indicator light 132 can be hidden inside the casing 12 to avoid the need to set a hole structure for the indicator light 132 to pass through in the casing 12, thereby greatly improving the waterproof performance of the handheld atomizer, thereby further improving the user's experience.

[0146] Implementation example 2. In this implementation example, the housing 12 is provided with a light display hole corresponding to the indicator light 132, and the housing 12 is provided with a translucent waterproof sticker covering the light display hole, so that the light emitted by the indicator light 132 passes through the light display hole and the translucent waterproof sticker and out of the housing 12 to clearly indicate to the user the working status of the handheld atomizer, and the translucent waterproof sticker can improve the waterproof performance of the handheld atomizer, thereby further improving the user's experience.

[0147] Further, refer to Figure 4The inner wall of the housing 12 is provided with a shading rib 124 opposite to the indicator light 132. The shading rib 124 surrounds the outer periphery of the indicator light 132, so that the shading rib 124 can block the light emitted by the indicator light 132 to prevent the light emitted by the indicator light 132 from diverging outward, thereby making the light emitted by the indicator light 132 more concentrated, thereby improving the lighting effect of the indicator light 132 and thereby improving the prompt effect for the user.

[0148] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0149] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0150] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
