[0002] Mucosal disinfectants are medical agents used on the mucous membranes of the mouth, nose, and genitals. They kill or remove pathogenic microorganisms on the mucous membranes to prevent and control infections. Mucosal disinfectants have diverse applications and can sometimes be used for disinfecting skin areas such as hands. In daily use, different locations of the mucous membrane usually require the atomized disinfectant to be sprayed in different directions. Specifically, when applying disinfectant to the nasal mucosa, the disinfectant spray bottle is usually required to spray the atomized disinfectant upwards to reach the nasal cavity. When applying disinfectant to other areas, such as the oral mucosa, genital mucosa, or skin areas like hands, the disinfectant spray bottle is usually required to spray the atomized disinfectant horizontally. Existing mucosal disinfectant spray bottles can only spray the atomized disinfectant in a fixed direction, making it difficult to meet the application requirements of different locations.

[0036] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0037] An embodiment of this utility model provides a mucosal disinfectant spray bottle, such as... Figure 1-6 As shown, it includes: bottle body 1, pump unit 2, and spray switching unit 3;

[0038] The pumping unit 2 is located at the bottle mouth of the bottle body 1 and is adapted to pump the liquid in the bottle body 1 to the switching spray unit 3;

[0039] The switching spray unit 3 includes: a housing 31, a valve core 32, and a control rod 35; the housing 31 is fixed to the pump pressure unit 2 and has a cavity 311, a through hole 312 communicating with the pump pressure unit 2 on the bottom surface, a first spray head 33 on the side wall, and a second spray head 34 on the top surface; the valve core 32 is installed in the cavity 311 and is adapted to reciprocate horizontally within the cavity 311; the valve core 32 has a first channel 321 communicating with the bottom surface and the side wall of the housing 31, and a second channel 322 communicating with the bottom surface and the top surface of the housing 31; the control rod 35 is fixed to the valve core 32 and is adapted to control the valve core 32 to switch between the position where the first channel 321 communicates with the through hole 312 and the first spray head 33, or the position where the second channel 322 communicates with the through hole 312 and the second spray head 34.

[0040] The mucosal disinfectant spray bottle described in this embodiment allows the valve core 32 to be switched between the first spray head 33 and the second spray head 34 by changing the position of the valve core 32 via the control lever 35. When the valve core 32 is in a position that connects the first channel 321 with the through hole 312 and the first spray head 33, the liquid supplied by the pump unit 2 can be sprayed out through the first spray head 33, achieving horizontal spraying of atomized medicine, suitable for disinfection of oral mucosa, genital mucosa, or skin areas such as hands. When the valve core 32 is in a position that connects the second channel 322 with the through hole 312 and the second spray head 34, the liquid supplied by the pump unit 2 can be sprayed out through the second spray head 34, achieving vertical spraying of atomized medicine, suitable for disinfection of nasal mucosa.

[0041] To achieve the purpose of this utility model, the design of the pumping unit 2 is not unique; any design that can pump the liquid in the bottle 1 to the switching spray unit 3 is acceptable. In this embodiment, a preferred implementation is provided, such as... Figure 2 As shown, the pump pressure unit 2 includes: a suction tube 21, a pump tube 22, a cover 23, and a pressing part 24.

[0042] The straw 21 is located inside the bottle body 1; the pump tube 22 is located at the top end of the straw 21 and communicates with the straw 21; a sealing ball 221 is provided inside the pump tube 22, and the sealing ball 221 is located at the connection between the straw 21 and the pump tube 22; the cap 23 is fixed to the outer periphery of the pump tube 22 and is adapted to be connected to the bottle mouth of the bottle body 1.

[0043] The pressing part 24 includes a pressing cover 241, a pressing tube 242, and a valve stem 243; the pressing cover 241 has a space to accommodate the switching spray part 3 and is located above the cover body 23; one end of the pressing tube 242 is connected to the through hole 312, and the other end is located inside the pump tube 22 and communicates with the pump tube 22; the valve stem 243 is located below the pressing tube 242 and is adapted to move up and down relative to the end of the pressing tube 242 to allow the pressing tube 242 to pass through or be sealed.

[0044] The operation of the pump pressure unit 2 is as follows: When the operator presses the pressing cover 241, the pressing part 24 moves downward, the cover 23 and the pump pipe 22 remain stationary, the pressing tube 242 moves downward along the inner wall of the pump pipe 22, the sealing ball 221 is engaged at the bottom end of the pump pipe 22, and the gas in the pump pipe 22 is discharged through the pressing tube 242; when the operator releases the pressing cover 241, the pressing tube 242 moves downward along the inner wall of the pump pipe 22. As the liquid moves upward, under the pressure difference between the pump tube 22 and the bottle body 1, the liquid in the bottle body 1 pushes open the sealing ball 221 and flows into the pump tube 22. After the pressure difference between the pump tube 22 and the bottle body 1 is balanced, the liquid is locked at the bottom of the pump tube 22, preventing the liquid entering the pump tube 22 from flowing back into the bottle body 1. After the operator presses and releases the pressing cap 241 repeatedly, the liquid in the bottle body 1 is continuously pumped to the switching spray unit 3.

[0045] As a preferred implementation of this embodiment, such as Figure 3 As shown, the pump tube 22 includes a chamber section 222, a liquid inlet section 223, and a plunger section 224 arranged sequentially; the diameter of the chamber section 222 is smaller than that of the liquid inlet section 223; the diameter of the liquid inlet section 223 is smaller than that of the plunger section 224; the sealing ball 221 is located inside the chamber section 222; a piston head 246 is sleeved on the outer periphery of the end of the pressing tube 242; the piston head 246 is adapted to move up and down inside the plunger section 224.

[0046] This configuration ensures that the piston head 246 moves only within the plunger section 224 and does not enter the liquid inlet section 223 or the plunger section 224, thus creating a pressure difference within the chamber section 222 and the liquid inlet section 223 during its vertical movement. Furthermore, the liquid inside the bottle 1 will not enter the gap between the pressing tube 242 and the pump tube 22 located above the piston head 246.

[0047] To enable the valve stem 243 to move up and down relative to the end of the pressing tube 242, and to allow the pressing tube 242 to pass through or seal through, this embodiment provides a preferred implementation method, such as... Figure 4As shown, one end of the valve stem 243 is located outside the pressing tube 242 and is provided with a retaining plate 244, while the other end is located inside the pressing tube 242 and is provided with a frustum-shaped sealing plug 245; the outer diameter of the retaining plate 244 is larger than the inner diameter of the chamber section 222;

[0048] The pressing tube 242 includes an upper pressing section 2421 and a lower pressing section 2422; the inner diameter of the upper pressing section 2421 is larger than that of the lower pressing section 2422, and a transition section 2423 is provided between the upper pressing section 2421 and the lower pressing section 2422, which is suitable for fitting the sealing plug 245.

[0049] With this configuration, when the pressing tube 242 moves downward, the valve stem 243, under the action of the locking platform 244, remains stationary above the chamber section 222. A vertical displacement occurs between the pressing tube 242 and the valve stem 243, causing the sealing plug 245 of the valve stem 243 to move away from the transition section 2423. A gap is formed between the sealing plug 245 and the inner wall of the pressing tube 242. Simultaneously, the inner diameter of the lower pressing section 2422 of the pressing tube 242 is smaller than the rod diameter of the valve stem 243, creating another gap between the pressing tube 242 and the valve stem 243. The liquid inside the bottle 1 flows upward through this gap. When the pressing tube 242 moves upward, the sealing plug 245 of the valve stem 243 returns to the position of the transition section 2423, achieving a seal.

[0050] To ensure the sealing performance of the valve stem 243 at the transition section 2423, a spring 225 is provided inside the pump pipe 22. One end of the spring 225 is located inside the chamber section 222, and the other end is fixed to the locking plate 244. The spring 225 allows the valve stem 243 to be tightly engaged at the transition section 2423 when the pressing tube 242 is in the apex position, i.e., when the operator is not pressing the pressing cover 241.

[0051] For achieving the purpose of this utility model, the structural design of the press cover 241 is not unique. In this embodiment, to facilitate the operator's pressing, the press cover 241 can be designed with the following structure: the press cover 241 includes a columnar segment 2411 and a curved segment 2412; the columnar segment 2411 is located below the switching spray section 3 and is suitable for embedding into the cover body 23; one end of the curved segment 2412 is connected to the columnar segment 2411, and the other end is located above the switching spray section 3, and has a curved surface, which is suitable for the operator to press.

[0052] It should be noted that the design of the control lever 35 is not unique, as long as it can adjust the position of the valve core 32. In this embodiment, the control lever 35 is located on one side of the housing 31, and the first spray head 33 is located on the other side of the housing 31.

[0053] To facilitate switching between the two spray states of the valve core 32, the spray switching unit 3 further includes a valve spring 36. The valve spring 36 is disposed within the housing 31, with one end contacting the side wall of the housing 31 and the other end contacting the valve core 32. This arrangement allows the spray switching unit 3 to be in the state of being connected to the first spray head 33 when the control lever 35 is not pressed, and in the state of being connected to the second spray head 34 when the control lever 35 is pressed. That is, the valve spring 36 allows the valve core 32 to fully reset when the control lever 35 is not pressed, and prevents it from stopping in other positions.

[0054] To facilitate limiting the valve spring 36, the first spray head 33 extends horizontally, and the valve spring 36 is sleeved on the outside of the first spray head 33.

[0055] As a preferred implementation of this embodiment, the mucosal disinfectant spray bottle may further include a limiting structure to limit the control lever 35, ensuring that the control lever 35 remains connected to the second spray head 34 after being pressed. For example, a positioning plate (not shown in the figure) may be used, which is rotatably mounted on the pressing cover 241. When the control lever 35 is pressed, the positioning plate is rotated to a position above the end of the control lever 35, preventing it from returning to its original position, thus facilitating the operator to perform other operations such as pressing the pressing cover 241 with one hand.

[0056] To facilitate pressing the press cap 241, the second spray head 34 is arc-shaped, with one end located on the top surface of the housing 31 and the other end extending towards the side closer to the first spray head 33. This design allows for more space to be reserved for the press cap 241.

[0057] The working process of the mucosal disinfectant spray bottle described in this embodiment is as follows:

[0058] When the operator presses the pressing cover 241, the pressing tube 242 moves downward, the piston head 246 moves downward, the cover 23 and its connected pump tube 22 remain stationary, the valve stem 243 is engaged in the chamber 222 under the action of the locking platform 244, the sealing plug 245 moves away from the transition section 2423, so that a gap is formed between the valve stem 243 and the pressing tube 242, thereby allowing the gas in the chamber section 222 and the liquid inlet section 223 of the pump tube 22 to enter the pressing tube 242 and be discharged through the switching spray section 3;

[0059] When the operator releases the pressing cap 241, the pressing tube 242 moves upward, the piston head 246 moves upward, the cap 23 and its connected pump tube 22 remain stationary, and the valve stem 243 remains on the chamber 222 under the action of the spring 225. The sealing plug 245 engages with the transition section 2423, sealing the valve stem 243 and the pressing tube 242, thereby creating a pressure difference between the chamber section 222 of the pump tube 22 and the bottle 1. The liquid in the bottle 1 flows upward through the suction tube 21 and pushes open the sealing ball 221 to enter the chamber section 222. After the pressure difference is balanced, the sealing ball 221 falls back, preventing the liquid that has entered the chamber section 222 from flowing back into the bottle 1.

[0060] Repeating the above process, the liquid in the bottle 1 passes through the straw 21, the chamber section 222, and the drainage section 223, enters the pressing tube 242 through the gap formed between the valve stem 243 and the pressing tube 242, and is delivered to the switching spray unit 3 through the through hole 312.

[0061] When the mucosal disinfectant spray bottle needs to spray a horizontally atomized agent, such as Figure 5 As shown, the through hole 312, the first channel 321, and the first spray head 33 of the switching spray unit 3 are in a connected state, and the atomized medicine is sprayed out through the first spray head 33. The atomized medicine is horizontal and is suitable for disinfection of oral mucosa, genital mucosa, or skin parts such as hands.

[0062] When it is necessary for the mucosal disinfectant spray bottle to spray vertically atomized medication, press the control lever 35, as shown. Figure 6 As shown, the through hole 312, the second channel 322, and the second spray head 34 of the switching spray unit 3 are in a connected state, and then the atomized medicine is sprayed out through the second spray head 34. The atomized medicine is in a vertical direction and is suitable for disinfection of parts such as the nasal mucosa.

[0063] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
