Description

Technical Field

[0001] This utility model relates to the technical field of disinfection equipment, specifically a high-pressure gun-type disinfection device. Background Technology

[0002] Disinfectant solutions are liquid disinfectants with characteristics such as broad bactericidal spectrum, strong bactericidal ability, rapid action, good stability, low toxicity, low corrosiveness, low irritation (they should be non-toxic, residue-free, non-corrosive, and non-irritating), easy solubility in water, safety for humans and animals, low cost and availability, and low environmental pollution. Because bacteria can easily grow in enclosed spaces, posing a risk to human health, appropriate gun-type disinfection devices are needed to spray disinfectant solutions into these spaces for sterilization and disinfection.

[0003] The announcement number "CN217067146U" discloses a high-pressure gun-type disinfection device. Through the use of a spray mechanism, the device can employ two different disinfection methods, allowing selection based on different specifications, areas, and sizes. This controls the liquid output, making disinfection more comprehensive, flexible, and efficient. Furthermore, the device's dosing mechanism allows for the addition of disinfectant without disassembling the bottle, eliminating the need for disassembly and improving ease of use.

[0004] However, the above technical solutions and existing technologies have the following drawbacks:

[0005] Firstly, the spray mechanism in this disinfection device uses a pressure pump to pressurize the disinfectant bottle, causing the bottle to easily expand and deform during use. Frequent expansion and deformation significantly shortens the bottle's lifespan. Secondly, the cap in this disinfection device is simply snap-fitted onto the wide opening. In actual use, this type of connection makes the cap prone to loosening and slipping under the impact of the disinfectant, resulting in poor practicality. Utility Model Content

[0006] The purpose of this invention is to provide a high-pressure gun-type disinfection device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-pressure gun-type disinfection device includes a handle, a cover, an outer shell, a spray pipe, and an atomizing nozzle. The handle is fixedly connected to the lower side of the annular side of the outer shell. The cover is installed on the right end of the outer shell. The spray pipe is installed on the left side of the outer shell. The atomizing nozzle is installed on the left end of the spray pipe. A spraying assembly is provided inside the outer shell for spraying disinfectant into the spray pipe. A connecting assembly is provided between the outer shell and the spray pipe for securely connecting the outer shell and the spray pipe.

[0009] Preferably, the spraying assembly includes a connecting sleeve, a storage bottle, a suction tube, a self-priming water pump, a power supply battery, and a discharge pipe. The power supply battery is installed on the right side inside the housing. The self-priming water pump is installed inside the housing. The suction tube is installed at the inlet of the self-priming water pump. The discharge pipe is installed at the outlet of the self-priming water pump. The connecting sleeve is fixedly connected to the lower side of the annular side of the housing. The storage bottle is installed inside the connecting sleeve.

[0010] Preferably, the connecting assembly includes a connecting groove, a connecting seat, a connecting head, a sealing ring, and a sealing ring. The connecting seat is installed at the left end of the housing. The connecting head is symmetrically arranged on the front and rear sides of the inner annular side of the connecting seat. The connecting groove is symmetrically opened on the front and rear sides of the annular side of the housing. The sealing ring is embedded in the middle position inside the connecting seat. The sealing ring is installed inside the sealing ring.

[0011] Preferably, the connecting seat has an internally threaded through hole on the upper side of its annular side, and a locking screw is installed inside the internally threaded through hole. The inner diameter of the connecting seat is the same as the outer diameter of the outer shell.

[0012] Preferably, the connecting groove is L-shaped, the connecting groove matches the connecting head, and the connecting seat and the ejector pipe are an integral structure.

[0013] Preferably, an annular sealing sheet is inserted inside the connecting sleeve, a replenishing tube is fixedly connected to the left side inside the outer shell, a sealing cap is installed at the upper end of the replenishing tube, and the sealing cap is connected to the replenishing tube by a threaded connection. The liquid storage bottle is made of transparent PVC, and the liquid storage bottle is connected to the connecting sleeve by a threaded connection.

[0014] Preferably, a control switch is installed on the upper side of the annular side of the outer shell, a charging base is installed on the right end of the shell cover, an anti-slip silicone sleeve is wrapped around the annular side of the handle, and a mesh dispersion sheet is fixedly connected to the left side inside the spray tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By starting the self-priming water pump, the pump draws the disinfectant from the storage bottle through the suction pipe and pressurizes it to the outlet pipe. The outlet pipe then guides the pressurized disinfectant into the spray pipe, where it is pre-dispersed by the mesh dispersion sheet. Finally, the disinfectant is atomized and sprayed outward through the atomizing nozzle to disinfect and sterilize the surrounding air. During this process, because the self-priming water pump pressurizes and sprays the disinfectant from the storage bottle using a suction method, and some external air is drawn into the storage bottle through the replenishment pipe, the pressure difference between the inside and outside of the storage bottle is kept balanced. Therefore, the storage bottle will not deform during use, thus ensuring its service life.

[0017] 2. During the installation of the connector, first insert the connector head into the corresponding connecting slot. After it is in place, rotate the connector to make the connector head rotate together and lock into the connecting slot. This prevents the connector from loosening or slipping during use. Then, tighten the locking screw into the internal threaded through hole to lock the connector and prevent it from rotating again. This ensures a stable connection between the connector and the outer shell and improves its practicality. Attached Figure Description

The handle 1 is fixedly connected to the lower side of the annular side of the outer shell 3, and the handle 1 and the outer shell 3 are an integral structure, allowing the user to easily handle the outer shell 3 by hand. The cover 2 is installed on the right end of the outer shell 3 and is detachable, facilitating future maintenance and repair of the internal power supply battery 47 and self-priming water pump 46. The spray pipe 6 is installed on the left side of the outer shell 3, and the spray pipe 6 guides the disinfectant into the atomizing nozzle. In the nozzle 7, an atomizing nozzle 7 is installed at the left end of the spray tube 6. The atomizing nozzle 7 can atomize the incoming disinfectant and spray it outward. The atomizing nozzle 7 is connected to the spray tube 6 by a threaded connection. The atomizing nozzle 7, which is connected to the spray tube 6 by a threaded connection, is easy to disassemble and use independently. The annular side of the handle 1 is wrapped with an anti-slip silicone sleeve 11, which makes the handle 1 more slip-resistant. A mesh dispersion sheet 61 is fixedly connected to the left side inside the spray tube 6. The mesh dispersion sheet 61 and the spray tube 6 are an integral structure. The mesh dispersion sheet 61 can pre-disperde the disinfectant that passes through.

[0028] The outer casing 3 is equipped with a spraying component 4, which is used to spray disinfectant into the spray pipe 6 so that the disinfectant can be sprayed outward through the spray pipe 6 and the atomizing nozzle 7. A connecting component 5 is provided between the outer casing 3 and the spray pipe 6, and the connecting component 5 is used to securely connect the outer casing 3 and the spray pipe 6 to prevent the spray pipe 6 from becoming loose or slipping during use.

[0029] The spray assembly 4 includes a connecting sleeve 43, a storage bottle 44, a suction pipe 45, a self-priming water pump 46, a power supply battery 47, and a discharge pipe 48. The power supply battery 47 is installed inside the outer casing 3 on the right side. The input terminal of the power supply battery 47 is electrically connected to the charging base 21 via a wire, and the output terminal of the power supply battery 47 is connected to the input terminal of the control switch 31 via a wire. The power supply battery 47 provides power to the self-priming water pump 46, which is a DC self-priming high-pressure water pump installed inside the outer casing 3. When powered on, the self-priming water pump 46, which is a DC self-priming high-pressure water pump, can draw disinfectant from the storage bottle 44 through the suction pipe 45 and pressurize and pump the disinfectant to the outlet pipe 48. The self-priming water pump 46 has a suction pipe 45 installed at the inlet, which is an integral structure with the outer shell 3. The suction pipe 45 facilitates the self-priming water pump 46 to draw disinfectant from the storage bottle 44. The self-priming water pump 46 has an outlet pipe 48 installed at the outlet, which can guide the disinfectant into the spray pipe 6.

[0030] A connecting sleeve 43 is fixedly connected to the lower side of the annular side of the outer shell 3. The connecting sleeve 43 and the outer shell 3 are an integral structure. The connecting sleeve 43 facilitates the installation and fixing of the liquid storage bottle 44 at the lower end of the outer shell 3. The liquid storage bottle 44 is installed inside the connecting sleeve 43. The liquid storage bottle 44 is made of transparent PVC. The transparent PVC liquid storage bottle 44 can not only temporarily store a certain amount of disinfectant, but also make it convenient for users to observe the remaining amount of disinfectant inside in real time. An annular sealing piece 431 is inserted inside the connecting sleeve 43. The annular sealing piece 431 makes the sealing between the liquid storage bottle 44 and the connecting sleeve 43 better. A replenishment tube 42 is fixedly connected to the left side of the inside of the outer shell 3. The replenishment tube 42 and the outer shell 3 are an integral structure.

[0031] A sealing cap 41 is installed at the upper end of the replenishment tube 42, and the sealing cap 41 is connected to the replenishment tube 42 by a threaded connection. The sealing cap 41, which is connected to the replenishment tube 42 by a threaded connection, can not only seal the upper end of the replenishment tube 42, but also facilitates its individual disassembly and assembly. The storage bottle 44 is connected to the connecting sleeve 43 by a threaded connection. The storage bottle 44, which is connected to the connecting sleeve 43 by a threaded connection, is easy for the user to disassemble and assemble. A control switch 31 is installed on the upper side of the annular side of the outer shell 3. The output end of the control switch 31 is electrically connected to the self-priming water pump 46 through a wire. The control switch 31 allows the user to control the self-priming water pump 46. A charging base 21 is installed on the right end of the shell cover 2. The charging base 21 allows the user to charge the power supply battery 47.

[0032] Example 2:

[0033] Based on Embodiment 1, in this embodiment, during the installation of the connector 52, the connector 55 is first inserted into the corresponding connecting groove 51. After insertion, the connector 52 is rotated so that the connector 52 drives the connector 55 to rotate together and be locked in the connecting groove 51, thus preventing the connector 52 from loosening or slipping during use. Then, the locking screw 53 is tightened and fixed in the internal threaded through hole 54 to lock the connector 52, thereby preventing the connector 52 from rotating again and ensuring the stability of the connection between the connector 52 and the outer shell 3.

[0034] The connecting assembly 5 includes a connecting groove 51, a connecting seat 52, a connecting head 55, a sealing ring 56, and a sealing ring 57. A connecting seat 52 is installed on the left end of the outer casing 3. The connecting seat 52 and the spray pipe 6 are integrally formed. The inner diameter of the connecting seat 52 is the same as the outer diameter of the outer casing 3. The connecting seat 52 facilitates the installation of the spray pipe 6 on the left side of the outer casing 3. Connecting heads 55 are symmetrically arranged on the front and rear sides of the inner annular side of the connecting seat 52. The connecting heads 55 are integrally formed with the connecting seat 52. Connecting grooves 51 are symmetrically formed on the front and rear sides of the annular side of the outer casing 3. The connecting grooves 51 are L-shaped and match the connecting heads 55. The matching connecting grooves 51 and connecting heads 55 facilitate the insertion of the connecting seat 52 onto the left side of the outer casing 3. A sealing ring 56 is embedded in the middle of the connector 52. The inner diameter of the sealing ring 56 is the same as the outer diameter of the outlet pipe 48. A sealing ring 57 is installed on the inner side of the sealing ring 56. The sealing ring 56 and the sealing ring 57 make the seal between the outlet pipe 48 and the connector 52 better, preventing the disinfectant from overflowing to the outside through the gap between the outlet pipe 48 and the connector 52. An internal threaded through hole 54 is opened on the upper side of the annular side of the connector 52. A locking screw 53 is installed inside the internal threaded through hole 54. The locking screw 53 is a wing screw. The internal threaded through hole 54 and the locking screw 53 can lock the connector 52, thereby preventing the connector 52 from loosening and slipping during use when it is snapped onto the left end of the outer casing 3.

[0035] Working principle: Before using this device, the user first loosens and removes the sealing cap 41, then adds an appropriate amount of disinfectant to the storage bottle 44 through the replenishment tube 42. After replenishment, the user can hold the handle 1 to pick up and use the device. During this process, simply start the self-priming pump 46 through the control switch 31. The self-priming pump 46 will then draw the disinfectant from the storage bottle 44 through the suction tube 45 and pressurize it to pump it into the outlet tube 48. At this time, the outlet tube 48 will guide the pressurized disinfectant into the spray tube 6 and be filtered by the mesh. The dispersing plate 61 performs pre-dispersion, and finally the disinfectant is atomized and sprayed outward through the atomizing nozzle 7 to disinfect and sterilize the surrounding air. When the user disassembles the atomizing nozzle 7, the disinfectant in the spray pipe 6 can be directly dispersed and sprayed outward through the mesh dispersing plate 61, thereby increasing the spray volume of disinfectant. Furthermore, because the self-priming pump 46 pressurizes and sprays the disinfectant inside the storage bottle 44 using a suction method, a portion of external air is simultaneously drawn into the storage bottle 44 through the replenishment pipe 42, maintaining a balance in the pressure difference between the inside and outside of the storage bottle 44. This prevents deformation of the storage bottle 44 during use, thus ensuring its service life. When disinfection is no longer needed, simply turn off the self-priming pump 46 via the control switch 31, and then install and fix the sealing cap 41 on the upper end of the replenishment tube 42 to prevent the disinfectant in the storage bottle 44 from flowing out through the replenishment tube 42. When installing the connecting seat 52 onto the left end of the outer casing 3, insert the connector 55 into the connecting groove 51. Once inserted, rotate the connecting seat 52 to allow it to... The movable connector 55 is fitted into the connecting groove 51 to prevent the connector 52 from loosening or slipping during use. Then, the locking screw 53 is tightened and fixed in the internal threaded through hole 54 to lock the connector 52 and prevent it from rotating again. This ensures the stability of the connection between the connector 52 and the outer shell 3. Later, simply loosen the locking screw 53 and rotate the connector 52 in the opposite direction. After it is rotated to the correct position, the connector 52 can be pulled to separate it from the outer shell 3, thus disassembling the connector 52.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
