[0027] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.
[0028] This application provides a liquid heating and injection device. This structure can heat the liquid within the cavity, so the extruded liquid is hot. The product can be used with a battery or power supply unit. When the liquid is pressed into the palm, it is warm. Furthermore, the liquid heating and injection device of this application can also be integrated into or used with other products. For example, when used with adult products, it can heat lubricant to lubricate the channel at a suitable temperature.
[0029] Please refer to the following: Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of an embodiment of the liquid heating jet device of this application. Figure 2 yes Figure 1 A cross-sectional view of the liquid heating injection device in the embodiment. Figure 3 yes Figure 1 A schematic diagram of the disassembled structure of the liquid heating jet device in this embodiment; the liquid heating jet device in this embodiment includes, but is not limited to, the following structures: housing 100, first valve assembly 200, heating element 300, and pressing assembly 400.
[0030] Specifically, the shell 100 surrounds and forms a first liquid storage chamber 101 and a second liquid storage chamber 102, which are connected by a liquid flow channel 103.
[0031] Optionally, the housing 100 in this embodiment may include a first housing 110, a second housing 120, and a third housing 130. The overall outer contour of the first housing 110, the second housing 120, and the third housing 130 may be a cylindrical structure. The second housing 120 is inserted into the first housing 110. The first end of the second housing 120 is used to cooperate with the first housing 110 to form a first liquid storage cavity 101. The second end of the second housing 120 is sealed with the third housing 130 to form a second liquid storage cavity 102.
[0032] The second housing 120 has a guide tube 140 at its first end. The guide tube 140 can be an integral structure with the second housing 120. The guide tube 140 forms a liquid flow channel 103. One end of the guide tube 140 is connected to the first liquid storage chamber 101, and the other end is inserted into the bottom of the second liquid storage chamber 102.
[0033] Optionally, in this embodiment, the volume of the second liquid storage chamber 102 is smaller than the volume of the first liquid storage chamber 101. The first liquid storage chamber 101 stores a large amount of liquid, while the second liquid storage chamber 102, serving as a heating chamber, only needs to store a small amount of liquid. This different liquid storage capacity design between the second liquid storage chamber 102 and the first liquid storage chamber 101 allows for control of the liquid heating time (reducing heating time) and improving the user experience.
[0034] Please refer to the following: Figure 4 , Figure 4 This is a partial structural schematic diagram of an embodiment of the liquid heating and spraying device of this application. In this embodiment, the first valve assembly 200 is provided corresponding to the liquid flow channel 103 and is used to block and open the liquid flow channel 103. When the first valve assembly 200 opens the liquid flow channel 103, the liquid in the first liquid storage chamber 101 can flow into the second liquid storage chamber 102 through the liquid flow channel 103.
[0035] Optionally, the first valve assembly 200 in this embodiment includes a first connector 210, a first spring 220, and a first sealing member 230. The first connector 210 is fixedly connected to the boss 122 inside the second housing 120, specifically by snap-fit. The first connector 210 has a liquid passage hole 211 in the middle for liquid to flow through.
[0036] One end of the first spring 220 abuts against the first connector 210, and the other end abuts against the first sealing member 230. In the absence of external force (no pressure difference between the first liquid storage chamber 101 and the second liquid storage chamber 102), the first spring 220 abuts against the first sealing member 230, causing the first sealing member 230 to block the liquid flow channel 103 (the funnel-shaped structure at the end), preventing liquid from flowing back from the second liquid storage chamber 102 into the first liquid storage chamber 101. The first sealing member 230 can be a small ball or a plug structure; no specific limitation is made here.
[0037] Please continue reading. Figure 2 and Figure 4 A heating element 300 is disposed within the second liquid storage chamber 102 for heating the liquid within the chamber. The heating element 300 can be any one or a combination of heating coils, ultrasonic heaters, resistance heating films, and resistance heating plates. In this embodiment, it can be a metal sheet structure, integrally injection molded with the housing (second housing 120). This design offers advantages such as structural stability and prevention of leakage.
[0038] The metal sheet has two parts: the first part is the connecting part 310, which is embedded in the second housing 120 and integrally injection molded with the second housing 120; the second part is the heating part 320, which extends into the second liquid storage chamber 102 to heat the liquid in the second liquid storage chamber 102.
[0039] Alternatively, please continue reading Figure 2 and Figure 3 One end of the pressing component 400 is located inside the second liquid storage chamber 102, and the other end protrudes from the housing 100. When the pressing component 400 is pressed, the liquid in the second liquid storage chamber 102 can be ejected through the through hole 411 on the pressing component 400.
[0040] In this embodiment, the pressing component 400 includes a button cap 410 and a sealing plug 420. The sealing plug 420 is disposed in the second liquid storage chamber 102. Under external pressing pressure, the button cap 410 can push the sealing plug 420 to move, thereby compressing the volume of the second liquid storage chamber 102, so that the liquid in the second liquid storage chamber 102 is ejected through the through hole 411 on the button cap 410. To improve the sealing performance, a first sealing rubber ring 421 can also be provided between the sealing plug 420 and the side wall of the second housing 120.
[0041] Optionally, the third housing 130 is provided with a liquid outlet channel 131 in the middle. The liquid heating and spraying device also includes a second valve assembly 500. The second valve assembly 500 is provided corresponding to the liquid outlet channel 131 and is used to block and open the liquid outlet channel 131. When the second valve assembly 500 opens the liquid outlet channel 131, the liquid in the second liquid storage chamber 102 can flow through the liquid outlet channel 131 and be sprayed out through the through hole 411 on the button cap 410.
[0042] Optionally, the second valve assembly 500 in this embodiment includes a second connector 510, a second spring 520, and a second sealing member 530. One end of the second connector 510 is fixedly connected to the button cap 410, and the other end is inserted into the liquid outlet channel 131 and can slide along the liquid outlet channel 131. A second sealing rubber ring 512 may be provided on the outer periphery of the second connector 510. The second connector 510 is provided with a connecting flow channel 511. The two ends of the connecting flow channel 511 are respectively connected to the through hole 411 of the button cap 410 and the liquid outlet channel 131 of the third housing 130. One end of the second spring 520 supports the second connector 510, and the other end supports the second sealing member 530.
[0043] In the absence of external force (there is no pressure difference between the second liquid storage chamber 102 and the liquid outlet channel 131), the second spring 520 holds the second sealing member 530, so that the second sealing member 530 blocks the liquid outlet channel 131 (the funnel-shaped structure at the end position). The second sealing member 530 can also be a small ball or a plug structure, which is not specifically limited here.
[0044] Alternatively, please continue reading Figure 2 and Figure 3 In this embodiment, the pressing component 400 also includes a reset spring 430, the two ends of which respectively hold the button cap 410 and the third housing, for resetting the button cap 410.
[0045] The working principle and process of the liquid heating injection device in this embodiment are as follows: First, liquid is injected into the first liquid storage chamber 101. Pressing the button cap 410 pushes the sealing plug 420 to slide along the second liquid storage chamber 102. During the reset process of the button cap 410 and the sealing plug 420, a negative pressure is formed in the second liquid storage chamber 102. Then, the first sealing member 230 of the first valve assembly 200 opens the liquid flow channel 103, and the liquid flows into the second liquid storage chamber 102 through the liquid flow channel 103. The heating member 300 heats the liquid flowing into the second liquid storage chamber 102. When the user presses the button cap 410 again... At 10 o'clock, under the action of negative pressure, the second sealing member 530 of the second valve assembly 500 is driven to open the liquid outlet channel 131. The heated liquid is sprayed out sequentially through the liquid outlet channel 131, the connecting flow channel 511, and the through hole 411 of the button cap 410. During the reset process of the button cap 410 and the sealing plug 420, negative pressure is formed again in the second liquid storage chamber 102. The first sealing member 230 of the first valve assembly 200 opens the liquid flow channel 103. The liquid flows into the second liquid storage chamber 102 through the liquid flow channel 103 and circulates sequentially, so that the liquid continuously enters the second liquid storage chamber 102 and is heated and sprayed out.
[0046] Alternatively, please continue reading Figures 1 to 3 The liquid heating and spraying device in this embodiment also includes a power supply unit 600, which is connected to the first housing 110 and electrically connected to the heating element 300. The power supply unit 600 can be a battery or other structural form.
[0047] Optionally, in this embodiment, the power supply unit 600 is detachably connected to the first housing 110. Please refer to the following: Figure 3 , Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of an embodiment of the liquid heating jet device of this application, showing the removal of the power supply unit. Figure 6 This is a schematic diagram of the installation structure of the power supply unit and the housing in an embodiment of the liquid heating and spraying device of this application. In this embodiment, the outer wall of the housing (specifically, the first housing 110) is provided with a mounting groove 112, and the power supply unit 600 is installed in the mounting groove 112.
[0048] The mounting groove 112 extends in the opposite direction to the axial direction of the first housing 110 and penetrates the end face of the first housing 110. The power supply unit 600 extends along... Figure 6 The power supply unit 600 is installed and secured in the mounting slot 112 in the direction of the middle arrow, with the power supply unit 600 fully secured in the mounting slot 112. Figure 1In the middle state), the outer side of the power supply unit 600 and the outer side of the housing together form a complete cylindrical surface or arc surface, or there is a small step difference between the outer side of the power supply unit 600 and the outer side of the housing, that is, the power supply unit 600 is just embedded in the mounting groove 112 of the housing, so that the overall appearance of the liquid heating spray device is coordinated.
[0049] Alternatively, please continue reading Figure 2 , Figure 3 as well as Figure 4 In this embodiment, the power supply unit 600 may include a housing 610, a battery cell 620, and a control circuit board 630. The battery cell 620 and the control circuit board 630 are disposed inside the housing 610. The housing 610 has exposed connection terminals 640. One end of the connection terminal 640 is connected to the control circuit board 630, and the other end is connected to the heating element 300. Specifically, it can be directly connected to the exposed part of the connection portion 310 of the heating element 300, or it can be connected via a probe. The connection terminal 640 can be a pogo pin structure. The detailed structure of the connection terminal 640 is within the understanding of those skilled in the art and will not be described in detail here.
[0050] Optionally, please refer to the following as well. Figure 2 and Figure 7 , Figure 7 This is a partial structural diagram of another embodiment of the liquid heating injection device of this application. In this embodiment, the bottom of the mounting groove 112 on the first housing 110 is provided with a liquid injection through hole 1120, which communicates with the first liquid storage chamber. The liquid injection through hole can be sealed by a rubber stopper 115, allowing the user to inject liquid into the first liquid storage chamber through the liquid injection through hole 1120. The liquid injection through hole 1120 does not affect the appearance, and an injection-type rubber stopper can also be used for sealing (the rubber stopper 115 can be detachable or non-detachable), providing excellent waterproof performance.
[0051] The liquid heating and spraying device provided in this application embodiment has two liquid storage chambers. A heating element is installed in one of the liquid storage chambers. The heating element can be used to heat the liquid before spraying, so that the sprayed liquid temperature is suitable and the user comfort is improved.
