Description

Technical Field

[0001] The utility model relates to the technical field of sprayers, in particular to a sprayer that is convenient for inverted spraying. Background Art

[0002] A sprayer is a device that atomizes and sprays a liquid using pressure, and is thus widely used in many fields such as household cleaning, medical treatment, agriculture, etc. The spray gun head of a traditional sprayer is directly screwed to a container filled with liquid. This causes gaps and looseness at the threaded connection when the spray gun head rotates relative to the container, and thus liquid leakage may occur. For example, during the stacked transportation of sprayers, some spray gun heads may be squeezed, resulting in relative rotation with the container and thus liquid leakage.

[0003] To this end, there are sprayers disclosed in the prior art, such as the Chinese utility model patent "A Handheld Sprayer Capable of Inverted Use" with the patent number CN202121066548.8 (publication number CN214932180U). Such sprayers further include a screw ring. The spray gun head is connected to the container through the screw ring, where the screw ring is screwed to the container, and the spray gun head can rotate relative to the screw ring, thus avoiding the problem of the screw ring rotating relative to the container when the spray gun head rotates, and can to a certain extent prevent liquid from leaking from the connection between the screw ring and the container.

[0004] However, such sprayers still have certain defects during actual use: Although the screw ring remains fixed relative to the container while the spray gun head rotates relative to the screw ring, since the spray gun head and the screw ring usually adopt end face sealing and can rotate relative to each other, the sealing performance between the spray gun head and the screw ring is relatively weak, and gaps may appear at the connection between the two, resulting in liquid leakage. Especially during inverted spraying, it is more likely to cause liquid leakage, which may cause situations such as waste, interfering with the normal use of operators, and even harming the operators. Therefore, there is still a need to further improve the existing sprayers. Summary of the Utility Model

[0005] The technical problem to be solved by the present utility model is to provide a sprayer that can prevent liquid from leaking from the connection between the spray gun head and the screw ring in view of the above-mentioned current situation of the prior art.

[0006] The technical solution adopted by the present utility model to solve the technical problem is as follows: The sprayer includes a spray gun head for spraying liquid and a screw ring for attaching to a container, and is characterized in that: it further includes a connecting member, the spray gun head is independently and detachably connected to the screw ring by means of the connecting member, the connecting member has an upper section for connecting to the spray gun head and a lower section for connecting to the screw ring, the spray gun head can rotate relative to the upper section in a sealed manner, and the screw ring is in static sealed cooperation with the lower section.

[0007] In order to enable the spray gun head to rotate relative to the upper section in a sealed manner, preferably, the spray gun head and / or the upper section have at least two first sealing portions for sealing. The first sealing portion can be a component such as an O-ring or a sealing ring integrally provided with the spray gun head and / or the first sealing portion, or can be set as an independently installed component such as an O-ring or a sealing ring according to actual needs, or the end faces of the spray gun head and the upper section can be sealed through the first sealing portion.

[0008] Furthermore, in order to enhance the sealing effect between the spray gun head and the first sealing portion, preferably, the upper section extends from the connecting member towards the spray gun head and at least partially enters the spray gun head to form, the first sealing portion is a sealing ring formed by at least partially protruding radially outwards from the upper section, and correspondingly, a first mating portion adapted to the first sealing portion is provided on the peripheral wall of the spray gun head. According to actual needs, the first mating portion can be set as a structure such as a sealing groove, so as to cooperate with the first sealing portion to enable the spray gun head to rotate relative to the upper section in a sealed manner.

[0009] For further design, in order to enable the first mating portion to cooperate with the first sealing portion to achieve a sealing effect, preferably, the first mating portion is a sealing groove formed by at least partially recessing radially inwards at a position on the peripheral wall corresponding to the first sealing portion. Setting a sealing groove structure on the peripheral wall to cooperate with the first sealing portion is not only relatively simple in structure but also relatively reliable.

[0010] In order to enable the upper section of the connecting member to be installed into the spray gun head, preferably, an accommodating space for at least partially inserting the upper section is further provided on the inner side of the peripheral wall of the spray gun head. Such a design is considered because there are other mechanisms such as a liquid guiding mechanism for spraying liquid in the spray gun head, and when the connecting member is installed into the spray gun head, the upper section of the connecting member may interfere with other mechanisms, so it is necessary to provide such an accommodating space to facilitate the installation of the connecting member.

[0011] Further design. To enable an accommodation space to be formed inside the peripheral wall, preferably, the connecting member is in a cylindrical structure, and at least a part of the interior of the spray gun head extends towards the connecting member to form a convex wall. The convex wall and the peripheral wall together enclose to form the accommodation space. By adopting the structure where the convex wall and the peripheral wall together enclose to form the accommodation space, while forming this accommodation space, the upper section of the connecting member can also be clamped between the convex wall and the peripheral wall, further strengthening the sealing between the connecting member and the peripheral wall to a certain extent.

[0012] To enable a static sealing fit to be achieved between the spiral ring and the lower section, preferably, a second sealing portion is provided between the lower section and the spiral ring. This second sealing portion can be provided with components such as sealing rings, sealing gaskets, etc., or the spiral ring and the end face of the lower section can be sealed through the second sealing portion.

[0013] Furthermore, to enable the second sealing portion to enable a static sealing fit between the spiral ring and the lower section, preferably, the lower section extends from the connecting member towards the spiral ring and at least partially enters the spiral ring to be formed, and the second sealing portion is a flange formed by at least a part of the lower section protruding radially outwards. Correspondingly, a second mating portion adapted to the second sealing portion is provided on the spiral ring.

[0014] Further design. To enable the second mating portion to cooperate with the second sealing portion to achieve a sealing fit, preferably, the second mating portion is a flange formed by at least a part of the end of the lower section protruding radially inwards, so as to form an end face seal with the second sealing portion. Designed in this way, on the one hand, a static end face seal can be formed, and on the other hand, the second mating portion can also limit the second sealing portion, so that the connecting member can be directly sleeved on the spiral ring, making the installation of the connecting member more convenient.

[0015] Compared with the prior art, the advantages of the present utility model are as follows: The connecting member of this sprayer has an upper section for connecting with the spray gun head and a lower section for connecting with the spiral ring, enabling the spray gun head to be independently connected to the spiral ring by means of the connecting member, enabling the spray gun head to rotate sealingly relative to the upper section, while the spiral ring maintains a static sealing fit with the lower section, thereby preventing liquid from leaking from the connection between the spray gun head and the spiral ring, and also facilitating the overall installation of the sprayer.

[0024] The following further describes the present utility model in detail with specific embodiments.

[0025] As Figures 1 to 8 shown, it is a preferred embodiment of the present utility model. Refer to Figure 1 、 Figure 2 , the sprayer in this embodiment includes a spray gun head 1 for spraying liquid and a spiral ring 2 for attaching to a container, and further includes a connecting piece 3. The spray gun head 1 is independently connected to the spiral ring 2 by means of the connecting piece 3. The connecting piece 3 has an upper section 31 for connecting to the spray gun head 1 and a lower section 32 for connecting to the spiral ring 2. The spray gun head 1 can rotate relative to the upper section 31 in a sealed manner, while the spiral ring 2 maintains a static sealed fit with the lower section 32.

[0026] In order to enable the spray gun head 1 to rotate relative to the upper section 31 in a sealed manner, the spray gun head 1 and / or the upper section 31 at least have two first sealing parts 311 for sealing. The first sealing part 311 can be a component such as an O-ring or a sealing ring integrally provided with the spray gun head 1 and / or the first sealing part 311, or can be set as an independently installed component such as an O-ring or a sealing ring according to actual needs, or the end faces of the spray gun head 1 and the upper section 31 are sealed through the first sealing part 311. Further, refer to Figure 3 、 Figure 4, in order to enhance the sealing effect between the spray gun head 1 and the first sealing portion 311, the upper section 31 extends from the connecting member 3 towards the spray gun head 1 and at least partially enters the spray gun head 1. The first sealing portion 311 is a sealing ring formed by at least partially protruding radially outward from the upper section 31. Correspondingly, a first mating portion 12 adapted to the first sealing portion 311 is provided on the peripheral wall 11 of the spray gun head 1. According to actual needs, the first mating portion 12 can be configured as a structure such as a sealing groove, etc., so as to cooperate with the first sealing portion 311 to enable the spray gun head 13 to rotate relative to the upper section 31 in a sealed manner. Refer to Figure 5 , Figure 6 , for further design, in order to enable the first mating portion 12 to cooperate with the first sealing portion 311 to achieve a sealing effect, the first mating portion 12 in this embodiment is a sealing groove, which is formed by at least partially recessing radially inward at a position on the peripheral wall 11 corresponding to the first sealing portion 311. And setting a sealing groove structure on the peripheral wall 11 to cooperate with the first sealing portion 311 is not only relatively simple in structure but also relatively reliable.

[0027] Secondly, in order to enable the upper section 31 of the connecting member 3 to be installed into the spray gun head 1, as Figure 6 shown, an accommodating space 13 for at least partially inserting the upper section 31 is further provided inside the peripheral wall 11 of the spray gun head 1. Such a design is considered because there are other mechanisms in the spray gun head 1, such as a liquid guiding mechanism for spraying liquid, etc. When the connecting member 3 is installed into the spray gun head 1, the upper section 31 of the connecting member 3 may interfere with other mechanisms. Therefore, it is necessary to provide an accommodating space 13 to facilitate the installation of the connecting member 3. For further design, in order to enable the inner side of the peripheral wall 11 to have an accommodating space 13, the connecting member 3 in this embodiment is a cylindrical structure, and at least partially protrudes towards the connecting member 3 inside the spray gun head 1 to form a convex wall 14. The convex wall 14 and the peripheral wall 11 jointly enclose the accommodating space 13. Adopting the structure of jointly enclosing the accommodating space 13 by the convex wall 14 and the peripheral wall 11 can, while forming the accommodating space 13, also enable the upper section 31 of the connecting member 3 to be clamped between the convex wall 14 and the peripheral wall 11, thereby further enhancing the sealing performance between the connecting member 3 and the peripheral wall 11 to a certain extent.

[0028] Finally, in order to achieve a static sealing fit between the spiral ring 2 and the lower section 32, a second sealing portion 321 is provided between the lower section 32 and the spiral ring 2. The second sealing portion 321 can be configured with components such as a sealing ring, a sealing ring, etc., or the end faces of the spiral ring 2 and the lower section 32 are sealed through the second sealing portion 321. Further, in order to enable the second sealing portion 321 to enable the spiral ring 2 and the lower section 32 to maintain a static sealing fit, refer to Figure 7 , Figure 8, the lower section 32 extends from the connecting member 3 towards the spiral ring 2 and at least partially enters the spiral ring 2 to form. The second sealing portion 321 is a flange formed by at least partially protruding radially outward of the lower section 32. Correspondingly, a second mating portion 21 adapted to the second sealing portion 321 is provided on the spiral ring 2. Further designed, in order to enable the second mating portion 21 to cooperate with the second sealing portion 321 to achieve a sealing fit, the second mating portion 21 in this embodiment is a flange formed by at least partially protruding radially inward at the end of the lower section 32, so as to form an end face seal with the second sealing portion 321. Designed in this way, on the one hand, a static end face seal can be formed, and on the other hand, the second mating portion 21 can also limit the second sealing portion 321, so that the connecting member 3 can be directly sleeved on the spiral ring 2, making the installation of the connecting member 3 more convenient.
