Description

Technical Field

[0002] Electric blankets are mainly used to increase the temperature of the bed when people sleep to achieve the purpose of heating, and can also be used to remove moisture from bedding. However, since electric blankets are currently mainly heated by electric heating wires, the electromagnetic radiation generated is far beyond the human body's tolerance range. Based on this, water-heated mattresses came into being. Water-heated mattresses are mainly composed of two parts: a mattress and a main body. The working principle is to heat water through the main body and transport it to the mattress through a water pump to warm the human body. The mattress uses water as a medium during the heating process and does not generate any electromagnetic radiation. It is especially suitable for pregnant women, the elderly, infants and young children, and other people who are not suitable for electric blankets.

[0003] The existing water-heated mattress has a hose inside the mattress, and the main body includes a cover shell, in which a water tank, a water pump, and a heating device are arranged. The heating device is connected to the water tank, and the water outlet of the water tank is connected to one end of the hose through the water pump, and the inlet of the water tank is connected to the other end of the hose, so that a water loop is formed between the water tank, the water pump, and the hose of the mattress. When working, the heating device heats the water in the water tank, and the heated water is pumped to the hose through the water pump. The hot water flows in the hose in the mattress to heat the mattress, and the water in the hose eventually flows back to the water tank from the other end to achieve heating of the mattress.

[0004] However, with the popularity of water-heated mattresses, the types of water-heated mattresses are increasing. For manufacturers, they need to produce different types of main bodies for different types of water-heated mattresses, which not only increases production costs, but also may cause material accumulation problems. Therefore, how to improve the versatility and adaptability of the main body has become an urgent problem to be solved. Utility Model Content

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1-6 This application is described in further detail.

[0041] The present application embodiment discloses a water-heated mattress host. Figure 1 The water-heating mattress host comprises a shell 1 , a host body 2 installed in the shell 1 , and a connecting component 3 for fixing the position of the host body 2 in the shell 1 .

[0042] Reference Figure 2 and Figure 3 The housing 1 is composed of a lower shell 12 and an upper shell 11, which are connected in a detachable manner to facilitate installation and disassembly. A mounting groove 13 is provided on the opposite side of the upper shell 11 and the lower shell 12, and the host body 2 is installed in the mounting groove 13 through the connecting component 3.

[0043] The host body 2 includes a water tank 21, a water pump 22 installed on one side of the water tank 21 and connected to the water tank 21, and a heater 23 installed on the water tank 21. The water inlet of the water pump 22 is connected to the water tank 21, and the water outlet 221 of the water pump 22 is used to connect to one end of the mattress hose. The water tank 21 is also provided with a water inlet 216, and the water inlet 216 is used to connect to the end of the mattress hose away from the water pump 22. The water tank 21 is used to store water, the heater 23 is used to heat the water in the water tank 21, the water pump 22 is used to transport the heated water in the water tank 21 to the mattress hose, and the water in the mattress hose flows from the water inlet 216 of the water tank 21 to the water tank 21, so as to heat the water by heating, and circulate in sequence.

[0044] Reference Figure 3 and Figure 4The connection assembly 3 includes a first snap ring 31 with an L-shaped cross section fixed to the side of the lower shell 12 facing the upper shell 11 and a second snap ring 32 with an L-shaped cross section fixed to the side of the upper shell 11 facing the lower shell 12. A U-shaped first embedding space 311 for the second snap ring 32 to be embedded is formed between the first snap ring 31 and the lower shell 12, and a U-shaped second embedding space 321 for the first snap ring 31 to be embedded is formed between the second snap ring 32 and the upper shell 11. When the upper shell 11 and the lower shell 12 are buckled together, the first snap ring 31 is embedded in the second embedding space 321, and the second snap ring 32 is embedded in the first embedding space 311, so that the seal between the upper shell 11 and the lower shell 12 is more tight.

[0045] The connecting assembly 3 also includes a first mounting column 33 fixedly connected to the bottom of the host body 2 and a first bolt 34 threadedly connected to the first mounting column 33. The first bolt 34 is passed through the lower shell 12, so that the relative position between the lower shell 12 and the host body 2 can be fixed by passing the first bolt 34 through the lower shell 12 and screwing it on the first mounting column 33.

[0046] Reference Figure 3 and Figure 5 The connection assembly 3 further includes a second mounting post 35 fixedly connected to the top of the host body 2, a third mounting post 36 fixedly connected to the upper shell 11, and a second bolt (not shown in the figure) screwed on the second mounting post 35, the second bolt is passed through the third mounting post 36, and the second screw is threadedly connected to the second mounting post 35. By passing the second bolt through the third mounting post 36 and screwing it on the second mounting post 35, the relative position between the host body 2 and the upper shell 11 can be fixed.

[0047] In order to prevent the second bolt from interfering with the installation of other parts, a recessed groove 361 for the second bolt to be embedded is provided on the third mounting column 36 , so that when the second bolt is screwed onto the second mounting column 35 , the second bolt head is also embedded in the recessed groove 361 .

[0048] Among them, a protective plug 24 is threadedly connected to the water filling port of the water tank 21, and the protective plug 24 is located on the side of the upper shell 11 away from the main body 2, so that when the main body 2 is installed on the shell 1, the water filling port can be closed by the protective plug 24, or the protective plug 24 can be removed from the water filling port to fill the water tank 21 with water.

[0049] The upper shell 11 and the lower shell 12 can be fixed together with the main body 2 by the first bolt 34 and the second bolt. In actual use, the same main body 2 can be produced, and then the main body 2 can be fixed on different types of shells 1 by the first bolt 34 and the second bolt, so as to meet the needs of different types of mattresses, thereby greatly improving the versatility and adaptability of the main body 2 to various types of water-heated mattresses.

[0050] It is understandable that the number of the first mounting column 33 , the second mounting column 35 and the third mounting column 36 can be designed to be multiple according to actual needs to meet the fixing requirements of the host body 2 and the shell 1 .

[0051] Reference Figure 2 A water outlet pipe 222 is fixedly connected to the water outlet 221 of the water pump 22, and a water inlet pipe 217 is fixedly connected to the water inlet 216 of the water tank 21. Protective caps 25 are detachably connected to the water outlet pipe 222 and the water inlet pipe 217. When the water-heating mattress host is not used after production, the water outlet pipe 222 and the water inlet pipe 217 can be sealed by the protective cap 25 to prevent foreign matter from entering.

[0052] Specifically, refer to Figure 6 The protective cap 25 includes a cap body 251 with one end closed and a protective head 252 detachably connected to the closed end of the cap body 251. The open end of the cap body 251 is threadedly connected to the water outlet pipe 222 or the water inlet pipe 217. At the same time, a socket 253 for inserting the protective head 252 is provided at the closed end of the cap body 251. Among them, the protective head 252 is open at one end, and the diameter of the protective head 252 gradually decreases from the open end of the protective head 252 to the closed end of the protective head 252. When in use, the closed end of the protective head 252 is directly inserted into the socket 253 from the open end of the cap body 251. Since the diameter of the protective head 252 gradually increases, the protective head 252 will be stuck at the socket 253, thereby fixing the position of the protective head 252 on the cap body 251. Then the open end of the cap body 251 is screwed onto the outlet pipe 222 or the inlet pipe 217 , and the outlet pipe 222 or the inlet pipe 217 is inserted into the protective head 252 , thereby fixing the position of the cap body 251 and sealing the end of the outlet pipe 222 or the inlet pipe 217 .

[0053] Reference Figure 3 and Figure 5 The water tank 21 includes a box body 211 and a box cover 212 mounted on the box body 211. The box body 211 and the box cover 212 are connected by fixing bolts 218. At the same time, in order to seal the inside of the box body 211, a sealing groove 213 is provided at the open end of the box body 211, and the sealing groove 213 is provided around the inside of the box body 211. At the same time, an annular sealing plate 214 that can be embedded in the sealing groove 213 is fixed to the box cover 212. When the box cover 212 is buckled on the box body 211, the sealing plate 214 is also embedded in the sealing groove 213 to form a U-shaped sealing structure, so that the sealing inside the box body 211 is more rigorous.

[0054] A sealing ring 215 is installed in the sealing groove 213 . When the sealing plate 214 is embedded in the sealing groove 213 , the sealing plate 214 will abut against the sealing ring 215 to ensure the seal between the sealing plate 214 and the bottom of the sealing groove 213 .

[0055] Reference Figure 2 A liquid level detection component 41 for detecting the water level in the water tank 21 is also installed on the water tank 21. The liquid level detection component 41 includes a minimum liquid level sensor 411 and a maximum liquid level sensor 412, and the liquid level detection component 41 is connected to the controller. At the same time, an alarm is also provided on the housing 1, and the alarm is also connected to the controller. When the minimum liquid level sensor 411 detects that the water level in the water tank 21 is lower than the set value, a water shortage instruction is input. After receiving the water shortage instruction, the controller inputs a warning instruction. After receiving the warning instruction, the alarm sounds an alarm, thereby reminding people to add water to the water tank 21. During the water adding process, when the maximum liquid level sensor 412 detects that the water in the water tank 21 is higher than the set value, a completion instruction is input. After receiving the completion instruction, the controller inputs a warning instruction. After receiving the warning instruction, the alarm sounds an alarm, thereby reminding people that the water adding is complete.

[0056] It is understandable that two red and green indicator lights can also be set. When the minimum liquid level sensor 411 detects that the water level in the water tank 21 is lower than the set value, the controller will control the red indicator light; when the maximum liquid level sensor 412 detects that the water level in the water tank 21 is higher than the set value, the controller will control the green indicator light.

[0057] Reference Figure 1 and Figure 2 A temperature sensor 42 is also installed on the water tank 21. The temperature sensor 42 is connected to the heater 23 through the controller. The temperature sensor 42 detects the water temperature in the water tank 21 in real time and transmits the detected data to the controller. When the controller receives the data detected by the temperature sensor 42 and it is less than the set value, the heater 23 is controlled to start heating the water in the water tank 21. Until the water in the water tank 21 is heated to the set value, when the temperature sensor 42 detects that the water temperature in the water tank 21 reaches the set value, the controller controls the heater 23 to stop.

[0058] Of course, a control panel 43 may also be installed on the housing 1 , and the control panel 43 is connected to the controller, so that the water volume and water temperature in the water tank 21 can be detected through the control panel 43 , and the set value can also be set through the control panel 43 .

[0059] The controller may be a PLC controller or a single-chip microcomputer, etc., as long as it can receive data and input control instructions when the data reaches a set value.

[0060] Of course, in actual use, it is necessary to set a fuse in the water tank. This solution preferably uses a double fuse solution so that when leakage occurs, the power can be cut off immediately, making it safer.

[0061] In the present application, a reserved hole (not shown in the figure) can also be pre-opened on the host body 2 so that a stainless steel screw can be installed in the reserved hole for subsequent use to serve as an electrode to detect the water level. The specific setting can be based on actual needs.

[0062] The implementation principle of a water-heating mattress host in an embodiment of the present application is as follows: during production, only the host body 2 needs to be produced, and then the corresponding shell 1 is produced according to the various models of water-heating mattress hosts required, and then the host body 2 can be installed in the corresponding shell 1. Since the cost of the shell 1 is relatively low, the cost increased by piling up various models of hosts is reduced, and the versatility and adaptability of the host body 2 are greatly improved.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
