Description

Technical Field

[0001] The utility model relates to the technical field of bathroom products, in particular to a handheld spray gun structure. Background Art

[0002] Most of the handheld spray guns currently on the market are press-to-discharge spray guns. When using them, you need to hold the entire spray gun with your hand first, and then raise your thumb to press the button on the spray gun to discharge water. This type of handheld spray gun has a large operating range and is not very convenient. In response to this, a handheld spray gun with a small operating range and convenient operation has emerged. For example, a technical solution with a patent number of 202120131300.9 and the name of "an adjustable spray gun" is disclosed in the Chinese patent literature. Please refer to the attached document of the prior art solution. Figure 4 With attached Figure 5 The scheme mainly includes an inlet end housing with an inlet channel, an outlet end housing with an outlet channel, a valve core with a rotating adjustment part, and a control member and a connecting device, wherein the control member includes an inner ring portion, an outer ring portion, a connecting portion, and a toggle portion, the inner ring portion and the outer ring portion are connected as a whole through the connecting portion, the toggle portion is integrally arranged on the outer ring portion, the outlet end housing is connected to the inlet end housing through the connecting device, the valve core is arranged between the inlet end housing and the outlet end housing, so as to connect the inlet channel with the outlet channel through the valve core, the control member is connected to the rotating adjustment part of the valve core through the inner ring portion, and the outer ring portion of the control member is sleeved on the connecting device. When in use, water can be discharged by horizontally toggling the toggle part, achieving the purpose of small and convenient operation. However, in actual application, this spray gun still has the following shortcomings: First, since the outer ring part of the control part is sleeved on the connecting device, the entire outer ring part is exposed. In this way, when grabbing the spray gun, the hand is easy to grasp or touch the outer ring part, which will affect the toggle, resulting in unsmooth toggling and inconvenience in use. Second, since the control part is an integrally formed structural component as a whole, and the control part is arranged between the water inlet end shell and the water outlet end shell, the water outlet end shell needs to pass through the control part through the connecting device to be connected with the water inlet end shell. This increases the number of structural parts of the spray gun as a whole, makes the structure complex, increases the difficulty of assembly, and is not simple enough as a whole. Therefore, in view of the above-mentioned shortcomings and deficiencies of the spray gun in the prior art, the applicant believes that it is very necessary to optimize and improve its structure in order to better meet people's application needs. Summary of the invention

[0003] The utility model aims to solve the above-mentioned problems and shortcomings and to provide a hand-held spray gun structure, in which only the toggle member of the control component of the hand-held spray gun structure is exposed, thereby ensuring the accuracy and smoothness of the toggle, and being very convenient and reliable to use. In addition, the movable sleeve and the toggle member are split components, which do not affect the connection between the water outlet shell and the water inlet shell, so that the water outlet shell and the water inlet shell can be directly docked and connected together without adding connecting parts, thereby making the overall structure of the spray gun simpler, thereby reducing the difficulty of assembly, increasing the assembly efficiency, and making the spray gun product more concise as a whole.

[0004] The technical solution of the utility model is implemented as follows: a handheld spray gun structure, including a water inlet end shell with a water inlet channel, a water outlet end shell with a water outlet channel, a valve core with a rotating adjustment part, and a control component, which is characterized in that one end of the water inlet end shell is connected to one end of the water outlet end shell, and a valve core installation cavity is also provided between the water inlet end shell and the water outlet end shell, and the valve core is arranged in the valve core installation cavity to connect the water inlet channel with the water outlet channel through the valve core; the water inlet end shell or the water outlet end shell is also provided with a waist-shaped through hole that penetrates into the valve core installation cavity and is arranged horizontally, and the control component includes a movable sleeve and a toggle member, the movable sleeve is arranged in the valve core installation cavity and is sleeved and connected to the rotating adjustment part, and one end of the toggle member passes through the waist-shaped through hole and is connected to the movable sleeve.

[0005] Preferably, one end of the water inlet end shell is provided with a first inner cavity connected to the water inlet channel, and one end of the water outlet end shell is provided with a second inner cavity connected to the water outlet channel, the first inner cavity and the second inner cavity constitute a valve core installation cavity, and the two ends of the valve core are respectively sealed and connected in the first inner cavity and the second inner cavity.

[0006] Preferably, an internal thread and an external thread that are threadedly connected to each other are provided between one end of the valve core and the second inner cavity, and a waterproof rubber ring is also provided between one end of the valve core and the second inner cavity.

[0018] like Figure 1 and Figure 2As shown, a handheld spray gun structure described in the utility model comprises a water inlet end shell 1 with a water inlet channel 11, a water outlet end shell 2 with a water outlet channel 21, a valve core 3 with a rotating adjustment part 31, and a control component 4. In order to achieve the purpose proposed by the utility model, one end of the water inlet end shell 1 is connected to one end of the water outlet end shell 2, and a valve core installation cavity is also provided between the water inlet end shell 1 and the water outlet end shell 2, and the valve core 3 is arranged in the valve core installation cavity to connect the water inlet channel 11 with the water outlet channel 21 through the valve core 3; the water inlet end shell 1 or the water outlet end shell 2 is also provided with a waist-shaped through hole 100 that penetrates through the valve core installation cavity and is arranged horizontally, and the control component 4 comprises a movable sleeve 41 and a toggle member 42, the movable sleeve 41 is arranged in the valve core installation cavity and is sleeved and connected to the rotating adjustment part 31, and one end of the toggle member 42 passes through the waist-shaped through hole 100 and is connected to the movable sleeve 41. In the control assembly 4 of the utility model, only the toggle member 42 is exposed, which ensures the accuracy and smoothness of the toggle, and is very convenient and reliable to use. In addition, the movable sleeve 41 and the toggle member 42 are split components, which do not affect the connection between the water outlet shell 2 and the water inlet shell 1, so that the water outlet shell 2 and the water inlet shell 1 can be directly connected together without adding connecting parts, making the overall structure of the spray gun simpler, the assembly difficulty is small, and the overall spray gun product is also simpler.

[0019] In order to make it easier to make a valve core installation cavity between the water outlet housing 2 and the water inlet housing 1, as shown in FIG. Figure 3 As shown, one end of the water inlet housing 1 is provided with a first inner cavity 12 connected to the water inlet channel 11, and one end of the water outlet housing 2 is provided with a second inner cavity 22 connected to the water outlet channel 21. The first inner cavity 12 and the second inner cavity 22 constitute a valve core installation cavity, and the two ends of the valve core 3 are respectively sealed and connected to the first inner cavity 12 and the second inner cavity 22. This can make the production and manufacturing of the valve core installation cavity easier.

[0020] In order to make one end of the valve core 3 firmly and tightly connected to the second inner cavity 22, as shown in FIG. Figure 3 As shown, an internal thread and an external thread that are screwed together are also provided between one end of the valve core 3 and the second inner cavity 22, and a waterproof rubber ring 5 that plays a sealing and waterproof role is also provided between one end of the valve core 3 and the second inner cavity 22. Specifically, the internal thread is arranged in the second inner cavity 22, and the external thread is arranged at one end of the valve core 3. In actual application, the external thread can also be arranged in the second inner cavity 22, and the internal thread can be arranged at one end of the valve core 3. Through the arrangement of the internal thread and the external thread, one end of the valve core 3 can be firmly connected to the second inner cavity 22. Through the arrangement of the waterproof rubber ring 5, a sealing effect can be played between one end of the valve core 3 and the second inner cavity 22 to prevent water leakage.

[0021] In order to enable the other end of the valve core 3 to be quickly and tightly connected to the first inner cavity 12, as shown in FIG. Figure 3 As shown, the other end of the valve core 3 is a sleeve connection end structure, the other end of the valve core 3 is nested in the first inner cavity 12, and a waterproof rubber ring 5 is provided between the other end of the valve core 3 and the first inner cavity 12 to seal and waterproof. Through such a nested connection structure design, the other end of the valve core 3 can be quickly connected to the first inner cavity 12 without affecting the connection between the water outlet housing 2 and the water inlet housing 1. Through the provision of the waterproof rubber ring 5, a sealing effect can be achieved between the other end of the valve core 3 and the first inner cavity 12 to prevent water leakage.

[0022] In actual application, the waist-shaped through hole 100 can be provided on the water inlet housing 1 or the water outlet housing 2. Preferably, the waist-shaped through hole 100 is provided on the water outlet housing 2, and the waist-shaped through hole 100 is provided through the second inner cavity 22. In this way, the space of the valve core installation cavity can be more compact, so that the overall volume of the spray gun can be controlled within a smaller range.

[0023] In order to make the water outlet housing 2 and the water inlet housing 1 be connected together easily and firmly, Figure 3 As shown, one end of the water inlet housing 1 is provided with an external thread connection part 13, and one end of the water outlet housing 2 is provided with an internal thread connection part 23, and the water outlet housing 2 is connected to the water inlet housing 1 by screwing the internal thread connection part 23 to the external thread connection part 13. In this way, the water outlet housing 2 and the water inlet housing 1 can be directly connected together, and the connection is very easy, firm, not easy to loosen, and reliable. Specifically, the internal thread connection part 23 is arranged in the second inner cavity 22, and the outer diameter of the external thread connection part 13 is smaller than the outer diameter of the water inlet housing 1, so as to form a step structure between the external thread connection part 13 and the water inlet housing 1. In this way, when the water outlet shell 2 and the water inlet shell 1 are docked and connected together, the external threaded connection part 13 extends into the second inner cavity 22 and is screwed together with the internal threaded connection part 23, and one end of the water outlet shell 2 is against the step structure, so that the external threaded connection part 13 and the internal threaded connection part 23 can be hidden, so that the external threaded connection part 13 and the internal threaded connection part 23 cannot be seen from the outside of the spray gun, which can make the overall spray gun more concise and easier to hold the spray gun.

[0024] In order to make the external thread connection part 13 and the internal thread connection part 23 more tightly connected, as shown in FIG. Figure 2As shown, a first waterproof damping rubber pad 6 is further provided between the external thread connection part 13 and the internal thread connection part 23. This not only plays a waterproof role, but also plays a connection damping role. Through the connection damping role, after the external thread connection part 13 and the internal thread connection part 23 are screwed together, the contact friction force and the tightness of the connection can be increased to achieve the purpose of preventing loosening. Specifically, the first waterproof damping rubber pad 6 is provided between the internal thread connection part 23 and the step structure.

[0025] In order to enhance the damping feeling of the toggle component 4, Figure 2 As shown, a second waterproof damping rubber pad 7 is also provided between the external threaded connection portion 13 and the movable sleeve wheel 41. This not only plays a waterproof role, but also plays a role in the toggle damping, so that the toggle assembly 4 will not be too loose or too tight, the toggle operation is more accurate, and the use is more reliable.

[0026] In order to make it easier to connect the toggle member 42 to the movable sleeve 41, the utility model provides two connection methods: the first one is as follows: Figure 4 As shown, the movable sleeve 41 is provided with an insertion hole 411, and one end of the toggle member 42 is inserted into the insertion hole 411. In actual application, in order to make the insertion connection more secure, one end of the toggle member 42 is firmly connected to the insertion hole 411 by an interference fit. Figure 5 As shown, the movable sleeve 41 is provided with an internal thread hole 412, and one end of the toggle member 42 is provided with an external thread portion 421, and one end of the toggle member 42 is connected to the movable sleeve 41 by screwing the external thread portion 421 with the internal thread hole 412. In this way, not only can the toggle member 42 be firmly connected to the movable sleeve 41, but also the assembly and disassembly are very convenient, which can improve the convenience of assembly.

[0027] In order to prevent the hand from slipping when in contact with the toggle member 42, Figure 5 As shown, the other end of the toggle member 42 is provided with an anti-skid pattern 422. This can increase the contact area and friction between the hand and the toggle member 42, thereby playing an anti-skid role, and making it more convenient and reliable to use.

[0028] In order to enable the toggle assembly 4 to more accurately toggle the rotation adjustment portion 31 without slipping, Figure 3 As shown, the rotation adjustment part 31 is provided with external spline teeth, and the movable sleeve 41 is provided with internal spline teeth adapted to the external spline teeth, and the internal spline teeth and the external spline teeth are engaged together. In this way, the connection between the movable sleeve 41 and the rotation adjustment part 31 can be more tightly connected, and there will be no slipping during the dialing process, ensuring that the rotation adjustment part 31 can be driven to rotate, which is very practical and reliable.

[0029] In actual application, there are two implementation modes for the channel shape structure of the water outlet channel 21 of the utility model: the first one is as follows: Figure 2 As shown, the water outlet channel 21 is a linear water outlet channel structure. Figure 6 and Figure 7 As shown, the water outlet channel 21 is a bent water outlet channel structure.

[0030] In order to improve the water discharge effect, Figure 2 and Figure 7 As shown, a water outlet nozzle 8 is also provided at the water outlet end of the water outlet channel 21 .
