Description

Technical Field

[0001] This utility model relates to the field of disinfection technology, and in particular to a disinfection device. Background Technology

[0002] The sterilizer contains a liquid reservoir filled with a disinfectant liquid. This liquid reacts to generate disinfectant gas within the reservoir. The sterilizer needs to expel this gas from the reservoir and disperse it into the environment to disinfect air and other substances. To maximize the gas's dispersion distance, a stronger airflow is required. One proposed technique involves blowing air into the reservoir to forcefully expel the disinfectant gas, thus increasing its distance. However, this strong airflow causes the reservoir to vibrate violently, generating significant noise that can be uncomfortable. Utility Model Content

[0003] The main purpose of this invention is to provide a sterilizer that aims to reduce the noise of the sterilizer.

[0004] To achieve the above objectives, the present invention proposes a sterilizer comprising a liquid storage cup and a fan. The liquid storage cup contains a liquid storage cavity; the liquid storage cup has a connecting port and an air outlet, the connecting port connecting the liquid storage cavity to the outside of the sterilizer, and the air outlet connecting the liquid storage cavity; the fan is connected to the liquid storage cup; the fan generates a first airflow to create a negative pressure on the air outlet side facing away from the liquid storage cavity; the negative pressure generates a second airflow, which enters the liquid storage cavity from the outside of the sterilizer through the connecting port, exits the liquid storage cavity through the air outlet, and merges with the first airflow.

[0005] In some embodiments, the liquid storage cup includes a cup body and a cup lid. The liquid storage cavity is formed in the cup body, and the cup body has an opening communicating with the liquid storage cavity. The cup lid covers the opening, and a silencing cavity is formed on the side of the cup lid facing away from the liquid storage cavity. The air outlet includes a first air outlet and a second air outlet that are spaced apart from each other on the cup lid. The first air outlet communicates with the opening, and the second air outlet communicates with the fan, so that the second airflow enters the silencing cavity from the liquid storage cavity through the first air outlet, and then merges with the first airflow through the second air outlet.

[0006] In some embodiments, the communication port is located on the cup lid; the sterilizer also includes a communication tube inserted into the communication port and passing through the silencing cavity to connect the outside of the sterilizer with the liquid storage cavity.

[0007] In some embodiments, the sterilizer further includes an air outlet pipe inserted into the first air outlet, the air outlet pipe connecting the silencing cavity and the liquid storage cavity; one end of the air outlet pipe and the connecting pipe connecting to the liquid storage cavity both extend from the cup lid into the liquid storage cavity.

[0008] In some embodiments, the vent pipe is radially adjacent to the connecting pipe.

[0009] In some embodiments, the sterilizer further includes a top cover, the cup cover having a vent on the side facing away from the opening, the top cover being disposed on the vent to enclose the silencing cavity with the cup cover; the top cover having a through hole communicating with the outside of the sterilizer; and a connecting tube extending from the opening to the through hole to pass through the silencing cavity and connect with the through hole.

[0010] In some embodiments, the upper cover is provided with a sealing element, and the cup lid is provided with a liquid exchange port communicating with the opening and the silencing cavity; the upper cover is configured such that when the upper cover is placed on the lid opening, the sealing element blocks the liquid exchange port, and the through hole connects to the communicating pipe.

[0011] In some embodiments, the sterilizer further includes a sterilization module connected to the liquid storage cup and used to sterilize the gas in the first airflow; the sterilization module is located upstream of the air outlet in the first airflow.

[0012] In some embodiments, the sterilizer further includes a support frame connected to the liquid storage cup, and both the fan and the sterilization module are mounted on the support frame for connection to the liquid storage cup via the support frame.

[0013] In some embodiments, an air guide tube is formed on the support and is connected to the air outlet, wherein the first airflow is used to generate the negative pressure at the end of the air guide tube away from the air outlet.

[0014] In this invention, the first airflow generated by the fan has a lower pressure because its velocity is higher than that of the surrounding environment. When the first airflow flows through the outlet side, it creates a negative pressure. The ambient gas outside the connecting port is attracted by this negative pressure, enters the liquid storage chamber from the outside through the connecting port, and then exits from the liquid storage chamber through the outlet, thus forming the second airflow. This second airflow guides the disinfectant gas out of the liquid storage cup. At the same time, the large air volume of the fan can accelerate the second airflow, allowing the disinfectant gas to be dispersed further. However, during this process, it is always the second airflow that flows through the liquid storage cup. The second airflow can be relatively weak and will not cause vibration in the liquid storage cup, thus reducing noise. Attached Figure Description

[0044] This utility model proposes a sterilizer.

[0045] Please see Figure 1 In some embodiments of this utility model, the sterilizer 100 includes a liquid storage cup 10 and a fan 20.

[0046] Please see Figures 2 to 5 The liquid storage cup 10 has a liquid storage cavity 11 inside. The liquid storage cup 10 has a connecting port 12 and an air outlet 13. The connecting port 12 is used to connect the liquid storage cavity 11 to the outside of the sterilizer 100, and the air outlet 13 is used to connect the liquid storage cavity 11.

[0047] The blower 20 is connected to the liquid storage cup 10. The blower 20 is used to generate a first airflow to create a negative pressure on the air outlet 13, which faces away from the liquid storage chamber 11. The negative pressure is used to generate a second airflow, which enters the liquid storage chamber 11 from the outside of the sterilizer 100 through the connecting port 12, and then exits the liquid storage chamber 11 through the air outlet 13, merging with the first airflow.

[0048] The sterilizer 100 has a reservoir cup 10 for storing disinfectant liquid. In one example, the reservoir cup 10 forms a reservoir chamber 11 containing water. The user can add items that react with water to generate disinfectant gas (such as disinfectant tablets, disinfectant pills, and disinfectants) to the water to form disinfectant gas within the reservoir chamber 11. The reservoir chamber 11 is not usually filled with water, allowing the disinfectant gas to accumulate in the water-free upper space for easy discharge from the reservoir chamber 11.

[0049] Fan 20 can be an axial flow fan, cross flow fan, or centrifugal fan, etc. Figure 1 In the embodiment shown, a centrifugal fan 20 is used, which is beneficial for generating a large flow rate and high velocity airflow.

[0050] The blower 20 can be directly connected to the liquid storage cup 10, for example, through fastening, screws (and bolts or rivets), or adhesive bonding. Alternatively, it can be connected indirectly to the liquid storage cup 10 via a bracket 70. The bracket 70 can also be connected indirectly to the liquid storage cup 10 by connecting to the bottom shell 82. For the connection between the blower 20 and the liquid storage cup 10, it is only necessary to ensure a stable relative position between the outlets 13 of the blower 20 and the liquid storage cup 10.

[0051] Please refer to Figure 4 ,exist Figure 4 In the illustrated embodiment, the connecting port 12 on the liquid storage cup 10 is located on the cup lid 15. In other embodiments, the connecting port 12 can also be located on the upper side of the cup body 14, that is, in a position where the liquid level in the liquid storage cavity 11 is generally not submerged, which can also serve to connect to the outside. In some embodiments that do not have a connecting pipe 30, the top cover 50 may also be omitted. Figure 3 As shown in the figure, by opening the connecting port 12 on the cup lid 15, it can be directly connected to the outside world.

[0052] Please refer to Figure 5 ,exist Figure 5 In the embodiment shown, the vent 13 on the liquid storage cup 10 is located on the cup lid 15. Figure 5 The image shows the second air outlet 132. For information on the first air outlet 131, please refer to [reference needed]. Figure 4 However, in other embodiments, the air outlet 13 can also be directly opened on the cup body 14, and the air outlet 13 only needs to connect the liquid storage chamber 11 with the airflow blown out by the fan 20.

[0053] The first airflow generated by the fan 20 is the airflow flowing from the inlet side of the fan 20 to the outlet side of the fan 20. Figure 1 In the middle, the dashed arrows indicate... Figure 1 In the illustrated embodiment, the direction of the first airflow is such that the first airflow flows radially through the opening 141 of the air duct 71. Since the air inlet side of the fan 20 receives air from the outside, the airflow formed on the outlet side has a higher velocity than the outside airflow. Therefore, when the first airflow passes through the air duct 71, a negative pressure is formed at the opening 141 of the air duct 71.

[0054] Please refer to the reference. Figure 1 and Figure 5As can be seen, the air guide tube 71 is connected to the second air outlet 132. The first airflow creates a negative pressure on the side of the air guide tube 71 away from the second air outlet 132, which is equivalent to creating a negative pressure at the air outlet 13, giving the air outlet 13 the power to draw in gas, thereby forming the second airflow. In some other embodiments, the air guide tube 71 may not be provided, and the first airflow may be allowed to flow directly from the side of the air outlet 13 away from the liquid storage chamber 11 to form the aforementioned negative pressure.

[0055] Since the aforementioned negative pressure is relative to the outside, when a negative pressure is formed at the outlet 13, the outlet 13 forms a negative pressure relative to the liquid storage chamber 11 (the air pressure inside the liquid storage chamber 11 is equal to the outside air pressure due to the setting of the connecting port 12). The gas inside the liquid storage chamber 11 is drawn away, and a negative pressure is formed relative to the outside again. In this way, the outside gas enters the liquid storage chamber 11 again through the connecting port 12, thus forming a second airflow.

[0056] Please refer to Figure 3 , Figure 3 The dashed line with an arrow indicates that the second airflow enters the liquid storage chamber 11 from the outside through the connecting port 12; please refer to... Figure 4 , Figure 4 The dashed line with arrows indicates that the second airflow enters the liquid storage chamber 11 from the outside through the connecting port 12, and then enters the silencer chamber 151 through the first air outlet 131; please refer to... Figure 5 , Figure 5 The dashed arrows indicate that the second airflow enters the air duct 71 from the silencer 151 through the second air outlet 132, then exits from the air duct 71, and subsequently merges with the first airflow. Figure 5 To avoid ambiguity, the first airflow is not shown, but its direction can be determined by referring to the position of the fan 20.

[0057] The above is in Figure 1 The illustrated embodiment shows the flow direction of the second airflow. However, in other embodiments, the second airflow may not follow the aforementioned flow path. For example, in some embodiments, the connecting port 12 and the air outlet 13 are respectively located on both sides of the cup body 14 in the radial direction (in this case, the silencer cavity 151 can be omitted), and the air guide pipe 71 is also omitted. In this case, the second airflow directly enters the liquid storage cavity 11 from the connecting port 12, and then flows out of the liquid storage cavity 11 from the air outlet 13 before directly merging with the first airflow.

[0058] It is evident that the negative pressure generated by the first airflow forms the second airflow, which can be relatively weak, thus not triggering the vibration of the liquid storage cup 10, and greatly reducing noise. At the same time, the first airflow can have a high flow rate and high volume, so that the second airflow is accelerated after merging with the first airflow and can be dispersed into a more distant space to complete the disinfection of the target space.

[0059] Please refer to Figures 3 to 5In some embodiments, the liquid storage cup 10 includes a cup body 14 and a cup lid 15. A liquid storage cavity 11 is formed inside the cup body 14. The cup body 14 has an opening 141 that communicates with the liquid storage cavity 11. The cup lid 15 covers the opening 141. A silencing cavity 151 is formed on the side of the cup lid 15 facing away from the liquid storage cavity 11. The air outlet 13 includes a first air outlet 131 and a second air outlet 132 that are spaced apart from each other on the cup lid 15. The first air outlet 131 communicates with the opening 141, and the second air outlet 132 is connected to a fan 20 so that the second airflow enters the silencing cavity 151 from the liquid storage cavity 11 through the first air outlet 131, and then merges with the first airflow through the second air outlet 132.

[0060] The cup body 14 and the cup lid 15 can be integrally formed, that is, they can be integrated through injection molding or welding, which improves the sealing of the liquid storage chamber 11. The cup body 14 and the cup lid 15 can also be screwed or snapped together. Figure 3 In the embodiment shown, the cup lid 15 and the cup body 14 are connected by a snap-fit ​​connection, and a sealing ring is also provided between the cup body 14 and the cup lid 15 to improve the sealing performance between the cup lid 15 and the cup body 14.

[0061] The first air outlet 131 serves as the air inlet of the silencer 151, and the second air outlet 132 serves as the air outlet of the silencer 151. This allows the second airflow to enter the silencer 151 through the first air outlet 131 and exit through the second air outlet 132. The silencer 151 has a relatively large volume (compared to the volume of pipes and other structures along the path of the second airflow), allowing sound waves to be absorbed and weakened within the silencer 151, thereby reducing noise and further improving the quietness of the sterilizer 100.

[0062] Please refer to Figure 6 In some embodiments, the connecting port 12 is provided on the cup lid 15. The sterilizer 100 also includes a connecting tube 30, which is inserted into the connecting port 12 and passes through the silencing cavity 151 to connect the outside of the sterilizer 100 and the liquid storage cavity 11.

[0063] After the connecting pipe 30 is inserted into the connecting port 12, the connecting port 12 exists as a cross-section of the connecting pipe 30 and does not necessarily serve to connect the liquid storage chamber 11 to the outside world on its own. However, since one end of the connecting pipe 30 is connected to the outside world and the other end is connected to the liquid storage chamber 11, it is equivalent to the connecting port 12 indirectly connecting the outside world and the liquid storage chamber 11 through the connecting pipe 30.

[0064] The connecting pipe 30 allows the disinfecting gas in the liquid storage chamber 11 to be further away from the outside (in embodiments where the connecting pipe 30 extends from the cup lid 15 to the outside of the liquid storage chamber 11), so that when the fan 20 is not working, the disinfecting gas in the liquid storage chamber 11 is less likely to spontaneously escape through the connecting pipe 30. This maintains the concentration of disinfecting gas in the liquid storage chamber 11, slows down the reaction rate between the disinfected items and water in the liquid, and prevents the rapid consumption of disinfected items when disinfection is not required; on the other hand, it prevents the leakage of high-concentration disinfecting gas, which could lead to environmental pollution.

[0065] The connecting pipe 30 can also pass through the silencing cavity 151. This allows the connecting pipe 30 to be hidden inside the silencing cavity 151 in the direction away from the liquid storage cavity 11, without protruding from the outer surface of the sterilizer 100, by utilizing the dimensions of the silencing cavity 151 in the direction away from the liquid storage cavity 11. However, in embodiments where the air inlet of the connecting pipe 30 needs to be further away from the liquid storage cavity 11, the connecting pipe 30 can be inserted directly into the cup body 14 without passing through the silencing cavity 151 (in which case the connecting port 12 is also opened on the cup body 14).

[0066] Please refer to Figure 7 In some embodiments, the sterilizer 100 further includes an air outlet pipe 40 inserted into the first air outlet 131, the air outlet pipe 40 connecting the silencer 151 and the liquid storage chamber 11; the ends of the air outlet pipe 40 and the connecting pipe 30 that connect to the liquid storage chamber 11 both extend from the cup lid 15 into the liquid storage chamber 11.

[0067] When the vent pipe 40 is inserted into the first vent 131, the first vent 131 may not be a separate vent 13, but rather exist as a section of the cross-section of the vent pipe 40. Figure 7 In the embodiment shown, the first air outlet 131 is the air outlet end face of the air outlet pipe 40.

[0068] When the ends of the vent pipe 40 and the connecting pipe 30 that connect to the liquid storage chamber 11 both extend from the cup cover 15 into the liquid storage chamber 11, all the openings 141 on the liquid storage cup 10 do not need to be adjacent to the inner wall of the liquid storage cup 10 (as mentioned below, in some embodiments, the cup cover 15 is also provided with a liquid exchange port 153, but considering that the liquid exchange port 153 can be blocked by the sealing member 52, it is not considered). In this way, as long as the liquid level in the liquid storage chamber 11 does not submerge the ends of the vent pipe 40 and the connecting pipe 30 that are in the liquid storage chamber, the liquid in the liquid storage chamber 11 will not spill out of the liquid storage chamber 11 through the connecting pipe 30 or the vent pipe 40, thus achieving the effect of preventing the liquid in the liquid storage chamber 11 from spilling out.

[0069] Please refer to Figure 7 It can be seen that in Figure 7In the illustrated embodiment, even if the sterilizer 100 is upside down relative to the state of step 7, as long as the amount of liquid in the liquid storage chamber 11 is not too large, the liquid will not submerge the vent pipe 40 and the connecting pipe 30, and therefore will not spill out of the liquid storage chamber 11. When the sterilizer 100 is in other states (e.g., placed on its side at various angles), the liquid will also not spill out of the liquid storage chamber 11.

[0070] Please refer to Figure 7 In some embodiments, the vent pipe 40 is radially adjacent to the connecting pipe 30.

[0071] The vent pipe 40 is adjacent to the connecting pipe 30. This can be achieved by bonding, welding, or integrally forming the vent pipe 40 and connecting pipe 30 together. Alternatively, the vent pipe 40 and connecting pipe 30 can simply abut against each other without any other connection. This abutment allows the vent pipe 40 and connecting pipe 30 to support each other, increasing their overall strength.

[0072] exist Figure 7 In the embodiment shown, since the liquid in the storage chamber 11 can be prevented from spilling out, the adjacent arrangement of the vent pipe 40 and the connecting pipe 30 can also make the openings 141 of the vent pipe 40 and the connecting pipe 30 in the liquid chamber as close as possible, and both are located close to the geometric center of the storage chamber 11. This further prevents liquid from spilling out of the storage chamber 11 from the vent pipe 40 and the connecting pipe 30, thus improving the spill prevention effect.

[0073] Please refer to Figure 7 and Figure 8 In some embodiments, the sterilizer 100 further includes a top cover 50, a cup lid 15 having a lid opening 152 formed on the side opposite to the opening 141, the top cover 50 covering the lid opening 152 to enclose the silencing cavity 151 with the cup lid 15; a through hole 51 communicating with the outside of the sterilizer 100 is formed on the top cover 50; a connecting tube 30 extends from the opening 141 to the through hole 51 to pass through the silencing cavity 151 and connect with the through hole 51.

[0074] This design allows a portion of the connecting tube 30 outside the liquid storage chamber 11 to extend into the silencing chamber 151, preventing it from protruding outside the sterilizer 100. This protects the connecting tube 30 from damage and prevents it from protruding beyond the sterilizer 100, thus avoiding an increase in its volume. The cup lid 15 also facilitates opening the silencing chamber 151 for maintenance of the components inside.

[0075] Please refer to Figure 3 and Figure 9In some embodiments, the upper cover 50 is provided with a sealing element 52, and the cup cover 15 is provided with a liquid exchange port 153 that connects the opening 141 and the silencing cavity 151; the upper cover 50 is configured such that when the upper cover 50 is placed on the cover opening 152, the sealing element 52 blocks the liquid exchange port 153, and the through hole 51 is connected to the connecting pipe 30.

[0076] A liquid exchange port 153 is provided on the cup lid 15, which connects to the opening 141. This allows the user to open the lid 50 and pour out the liquid from the storage chamber 11 through the liquid exchange port 153, facilitating liquid replacement. The through hole 51 and the connecting tube 30 are connected to form a mutually restrictive structure between the lid 50 and the connecting tube 30. This ensures that the lid 50 is in a preset position when closed, aligning the sealing element 52 with the liquid exchange port 153 and preventing leakage. The connection between the through hole and the connecting port 12 also allows the user to directly insert sterilized items (tablets or pills, etc.) into the storage chamber 11 through the through hole and the connecting tube 30, facilitating use.

[0077] Please refer to Figure 10 and Figure 12 The cup lid 15 can be rotatably connected to the liquid storage cup 10, the bracket 70 or the outer shell 81, so that the cup lid 15 can be flipped to open the silencer chamber 151 or cover the lid opening 152.

[0078] Please refer to Figure 8 In some embodiments, the sterilizer 100 further includes a sterilization module 60, which is connected to the liquid storage cup 10 and is used to sterilize the gas in the first airflow; the sterilization module 60 is located at the air outlet 13 in the first airflow. Figure 8 The image shows the upstream of the second air outlet (132).

[0079] The disinfection module 60 can be a plasma disinfection module 60, an ultraviolet disinfection module 60, or an ozone disinfection module 60, etc., which can play a disinfection role. Among them, the plasma disinfection module 60 can also play a deodorizing role. When used in combination with the chemical disinfection in the liquid storage chamber 11, it can achieve a broad-spectrum sterilization and deodorization effect.

[0080] The disinfection module 60 may also contain aromatherapy ingredients to release fragrance substances into the air for an aromatherapy effect. Alternatively, volatile aromatherapy substances may be added to the liquid chamber, allowing them to be released into the air with the second airflow for an aromatherapy effect.

[0081] The disinfection module 60 is located upstream of the air outlet 13. This way, the first airflow is disinfected by the disinfection module 60 and then merges with the second airflow. This ensures that the disinfected gas in the second airflow will not be decomposed by the disinfection module 60, thus guaranteeing the effectiveness of the disinfected gas in the second airflow.

[0082] Please refer to Figure 9 and Figure 12 In some embodiments, the sterilizer 100 further includes a bracket 70, which is connected to the liquid storage cup 10. The fan 20 and the sterilization module 60 are both mounted on the bracket 70 and connected to the liquid storage cup 10 through the bracket 70.

[0083] The bracket 70 ensures the stability of the positional relationship between the fan 20 and the disinfection module 60, preventing misalignment during use. Furthermore, the bracket 70 facilitates the installation of the fan 20 and the disinfection module 60. Mounting positions can be designed on the bracket 70 to accommodate the structures of the fan 20 and the disinfection module 60. For example, a snap-fit ​​position can be designed for the disinfection module 60, allowing its base to be fixed to the bracket 70. Simultaneously, a matching mounting position can be provided for the fan 20, allowing it to be secured to the bracket 70 using screws, bolts, or rivets.

[0084] The bracket 70 itself can have an installation structure, so that the bracket 70 can be connected to the base and / or liquid storage cup 10 and other structures, so that the fan 20 and the disinfection module 60 are stably positioned inside the entire sterilizer 100.

[0085] Please refer to Figure 8 In some embodiments, an air duct 71 is formed on the support 70, the air duct 71 is connected to the air outlet 13, and the first airflow is used to generate negative pressure at the end of the air duct 71 away from the air outlet 13.

[0086] The air duct 71 allows the fan 20 to be properly positioned away from the liquid storage cup 10, so that the vibration of the fan 20 will not be transmitted to the liquid storage cup 10 and will not directly excite the vibration of the liquid storage cup 10, thus making the sterilizer 100 quieter.

[0087] Please refer to Figure 10 and Figure 11 In some embodiments, the sterilizer 100 also includes a hanging plate 822, with a hanging hole 8221 provided on the scraper.
